Verificación del impacto de la educación sexual en adolescentes en la consulta externa de dos IPS de Bogotá

En este estudio se realizó una encuesta con el fin de evidenciar el conocimiento y la práctica de la Educación Sexual en adolescentes que acudieron al servicio de consulta externa de Medicina General en dos Instituciones Prestadoras de Servicios de Salud (IPS) de la ciudad de Bogotá, una de régimen contributivo y otra de régimen subsidiado. Se realizó un estudio observacional, descriptivo, de corte transversal, a 100 adolescentes, mujeres y hombres, a través de la aplicación de un instrumento prediseñado con un contenido de 17 preguntas donde se indagó acerca de: planificación familiar, conducta sexual, educación sexual, embarazo adolescente y conductas de riesgo en adolescentes. En relación al régimen de aseguramiento en salud que tenían los adolescentes, las diferencias encontradas en sus respuestas fueron a nivel de: educación sexual recibida, acceso a los servicios de planificación familiar de las Empresas Promotoras de Salud (EPS), presencia de embarazo adolescente y consumo de alcohol asociado a la práctica de relaciones sexuales. Tras el análisis de la información obtenida con la aplicación de la encuesta, se concluye que es indispensable crear en las instituciones educativas públicas y privadas de la ciudad de Bogotá, una nueva herramienta metodológica a través de la cual se realice promoción de la salud y refuerzo de prácticas protectoras en educación sexual para adolescentes, pues persiste desconocimiento de la misma.

Genética, riesgo y derecho penal: una aproximación interdisciplinaria

Este texto presenta un estudio científico y jurídico sobre la genética y el derecho penal, con el objeto de realizar un pequeño aporte para la superación de la polarización política y moral de los debates sobre la genética y el derecho, que sólo ha conducido a una desafortunada paralización de la regulación sobre el tema que aumenta los riesgos para la salud humana y el equilibrio de los ecosistemas. Ante una problemática tan compleja, el derecho moderno no plantea una solución unitaria, sino una metodología a través de la cual cada sociedad democráticamente pueda adoptar sus propias decisiones frente a la salvaguarda de su patrimonio genético.

A platform for supporting micro-collaborations in a diverse device environment

Collaborative software is usually thought of as providing audio-video conferencing services, application/desktop sharing, and access to large content repositories. However mobile device usage is characterized by users carrying out short and intermittent tasks sometimes referred to as 'micro-tasking'. Micro-collaborations are not well supported by traditional groupware systems and the work in this paper seeks out to address this. Mico is a system that provides a set of application level peer-to-peer services for the ad-hoc formation and facilitation of collaborative groups across a diverse mobile device domain. The system builds on the Java ME bindings of the JXTA P2P protocols, and is designed with an approach to use the lowest common denominators that are required for collaboration between varying degrees of mobile device capability. To demonstrate how our platform facilitates application development, we built an exemplary set of demonstration applications and include code examples here to illustrate the ease and speed afforded when developing collaborative software with Mico.

CGIAR research program on grain legumes

EXECUTIVE SUMMARY Background and context The Grain Legumes CRP was established to bring all research and development work on grain legumes within the CGIAR system under one umbrella. It was set up to provide public goods outcomes to serve the needs of the sustainable production and consumption of grain legumes in the developing world, capitalising upon their properties that enhance the natural resource base upon which production so unequivocally depends. The choice of species and research foci were finalised following extensive consultation with all stakeholders (though perhaps fewer end users), and cover all disciplines that contribute to long-lasting solutions to the issues of developing country production and consumption. ICRISAT leads Grain Legumes and is partnered by the CGIAR centers ICARDA, IITA and CIAT and a number of other important partners, both public and private, and of course farmers in the developed and developing world. Originally in mid-2012 Grain Legumes was structured around eight Product Lines (PL) (i.e. technological innovations) intersecting five Strategic Components (SC) (i.e. arranged as components along the value chain). However, in 2015, it was restructured along a more R4D output model leading to Intermediate Development Outcomes (IDOs). Thus five Flagship Projects (FP) more closely reflecting a systematic pipeline of progression from fundamental science, implementation of interventions and the development of capacity and partnerships to promote and adopt impactful outcomes: FP1) Managing Productivity through crop interactions with biotic and abiotic constraints; FP2) Determination of traits that address production constraints and opportunities; FP3) Trait Deployment of those traits through breeding; FP4) Seed Systems, post-harvest processing and nutrition; FP5) Capacity-Building and Partnerships. Another three cross-cutting FPs analyse the broader environment surrounding the adoption of outputs, the capitalising of investments in genomics research, and a focus on the Management and Governance of Grain Legumes: FP6) Knowledge, impacts, priorities and gender organisation; FP7) Tools and platforms for high throughput genotyping and bioinformatics; and FP8) Management and Governance. Five FPs focus on R4D; FPs 5 and 6 are considered cross-cutting; FP 7 has a technical focus and FP 8 has an overarching objective. Over the three year period since its inception in July 1012, Grain Legumes has had a total budget of $140 million, with $62M originally to come from W1/W2 and the remaining $78M to come from W3/bilateral. In actuality only $45M came from W1/W2 but $106M from W3/bilateral corresponding to 106% of expectation. Purpose, scope and objectives of the external evaluation Principally, the evaluation of Grain Legumes is to ensure that the program is progressing in an effective manner towards addressing the system-level outcomes of the CGIAR as they relate to grain legumes. In essence, the evaluation aims to provide essential evaluative information for decision-making by Program Management and its funders on issues such as extension, expansion and structuring of the program and adjustments in relevant parts of the program. Subsequent to the formal signing of the agreed terms of reference, the evaluation team was also invited to comment upon the mooted options for merging and/or disaggregating of Grain Legumes. The audiences are therefore manifold, from the CGIAR Fund Council and Consortium, the Boards of Trustees of the four component CGIAR centres, the Grain Legumes Steering, Management and Independent Advisory Committees, to the researchers and others involved in the delivery of R4D outcomes and their partner organisations. The evaluation was not only summative in measuring results from Grain Legumes at arm’s length; it was also formative in promoting learning and improvements, and developmental in nurturing adaption to transformational change with time. The evaluation report was written in a manner that allows for engagement of key partners and funders in a dialogue as to how to increase ownership and a common understanding of how the goals are to be achieved. We reviewed research undertaken before the CRPs but leading to impacts during Grain Legumes, and research commenced over the past 2.5 years. For related activities pre- and post-commencement of Grain Legumes, we reviewed the relevance of activities and their relation to CGIAR and the Grain Legumes goals, whether they were likely to lead to the outcomes and impacts as documented in the Grain Legumes proposal, and the quality of the science underpinning the likelihood to deliver outcomes. Throughout, we were cognisant of the extent of the reach of CGIAR centres’ activities, and those of stakeholders upon which the impact of CGIAR R4D depends. Within our remit we evaluated the original and modified management and governance structures, and all the processes/responsibilities managed within those structures. Besides the evaluation of the technical and managerial issues of Grain Legumes, we addressed cross-cutting issues of gender sensitivity, capacity building and the creation and nurturing of partnerships. The evaluation also has the objective to provide information relating to the development of full proposals for the new CRP funding cycle. The evaluation addressed six overarching questions developed from the TOR questions (listed in the Inception Report, 2015 [http://1drv.ms/1POQSZh] and others including cross-cutting issues, phrasing them within the context of traditional evaluation criteria: 1. Relevance: Global development, urbanisation and technological innovation are progressing rapidly, are the aims and focus of Grain Legumes coherent, robust, fit for purpose and relevant to the global community? 2. Efficiency: Is the structure and effectiveness of leadership across Grain Legumes developing efficient partnership management and project management across PLs? 3. Quality of science: Is Grain Legumes utilising a wide range of technologies in a way that will increase our fundamental understanding of the biology that underpins several PLs; and are collected data used in the most effective way? 4. Effectiveness: Are Product Lines strategic contributors to the overarching aims and vision for Grain Legumes? 5. Impact: Are the impact pathways that underlie each PL well defined, measureable and achievable; and are they sufficiently defined in terms of beneficiaries? Does progress towards achieving outputs and outcomes from the major research areas indicate a lasting benefit for CGIAR and the communities it serves? 6. Sustainability: Is Grain Legumes managing the increasing level of restricted funding in terms of program quality and effectiveness, including attracting and retaining quality staff? Questions for the evaluation of governance and management focused on accountability, transparency, the effectiveness and success of program execution, change management processes and communication methods, taking account of the effects of CGIAR reform. The three crosscutting issues were considered as follows: i) gender balance in program delivery, e.g. whether each PL is able to contribute to the increased income, food security, nutrition, environmental and resource conservation for resource-poor women and men existing in rural livelihoods; ii) are internal and external capacity gaps identified/met, is capacity effectively developed within each product line, and are staff at all levels engaged in contributing ideas towards capacity building; and iii) is there effective involvement of partners in research and activity programming, what are the criteria for developing partnerships, how they are formalised and how is communication between partners and within Grain Legumes managed? It was not in remit to search for output, outcomes or impact, however as highlighted later, much of our time was spent on searching for information to support claims of impact, since Grain Legumes had no effective dedicated M&E in place at the time of undertaking the review. Approach and methodology The evaluation was conducted when Grain Legumes had been operational for approximately 3 years. The approach and methodology followed that outlined in the Inception Report [http://1drv.ms/1POQSZh]. The CCEE Team based its findings, conclusions and recommendations on data collection from several sources:  review of program documents, communications with the CO, minutes and presentations from all management and governance committee meetings  review of previous assessments and evaluations  sampling of Grain Legume projects in 7 countries1  more than 66 face to face interviews, a further 133 persons in groups and 4 phone/Skype conversations: ICRISAT, ICARDA, CIAT and IITA staff, partners and stakeholders. Meetings with one Independent Science and Partnership Council (ISPC) member.  meetings with over 100 people in 16 external groups, such as farmers’ groups  online survey completed by 126 (33.4%) scientists who contribute to Grain Legumes and a number of non-CGIAR partners and Management representatives  bibliometric review of 10 publications within each PL to qualitatively assess the design, conduct, analysis and presentation of results  quantitative and qualitative self-assessment of the contributions of each of the PLs to the six criteria and 3 cross-cutting issues of evaluation mentioned above completed by PLCs (see below). We reviewed the Logical Framework that underpins the desired Goals, or Impacts of Grain Legumes, and the links between the outputs and inputs as they related to the organisational units of Grain Legumes. The logical framework approach to planning and management of Grain Legumes activities implies a linear process, leading from activities, outputs, outcomes, to impacts, but within such an approach there may be room for a more systems dynamics approach allowing for feedback at every step and within every step, in order to refine and improve upon the respective activities as new results, ideas, and directions come to light. We then developed a matrix that summarised quantitatively and qualitatively the contributions of each of the PLs to the six criteria and 3 cross-cutting issues of evaluation mentioned above. Main findings and conclusions Grain legume production and consumption remain of great importance to the food security of not inconsiderable populations in the developing world, and merit sustained research investment. We conclude that Grain Legumes continues to contribute significant returns to research investments by the CGIAR, and such investment should continue. The global research community looks to the CGIAR for leadership in Grain legumes, but needs to be assured of value adding when bringing CGIAR centres under the expected umbrella of synergy. However, there is considerable scope for improving the efficiency with which outcomes are achieved. We note that an absence of an effective M&E has hampered the assessment of the effectiveness of proposed impact pathways. Likewise progress has been hampered by the limited numbers of research partnerships with Advanced Institutes and by budgetary constraints (lamented for their stifling effects on continuation of ongoing exciting research). The unworkable management structure constrains the CRP Director’s leadership role; responsibility without authority will never lead to effective outcomes. Good fortune is responsible for many of the successes of Grain Legumes, underpinned by a devoted work force across the participating CGIAR centres and partners. The quality of the science is not uniformly high, and we believe that mentoring of scientists should be given priority where quality is poor. Simplified yet informative reporting is an imperative to this. World class science underpins the identification of, and molecular basis for, traits important for yield improvement and this expertise should be extended to all grain legume species, capitalising upon the germplasm collections. The linking of Grain Legumes with regional research and development consortia has been very successful, with outcomes aligning with those of Grain Legumes. We see that with declining funding consolidation of research effort based on likely successes will be necessary, and welcome the move afoot to incorporate grain legumes into an agri-food system focused on successful value chains that deliver sustainable outcomes. Relevance and Strategy Grain Legumes has geographic and disciplinary relevance, addressing the major supply chain issues of variety development seed system and agronomy, with some attention to quality and postharvest marketing systems. The CRP has provided the opportunity to cut ongoing and to initiate new research. Research funded by the Gates Foundation (Anon, 2014) suggests that the need for improvement is greatest in Africa and advocates reducing the number of crop by country combinations when resources are sparse. The lesser research investment in Latin America, however, is not in line with the regions’ dependency on legumes. In spite of the fact that there is no evidence of strong inter-partner CGIAR centre or internal synergy, the program is still moving ahead on most fronts in line with the overall project logframe. This is in spite of continual pushing and pulling by in particular donors and the CO. However, to quantify real impact, we believe Grain Legumes must have access to reliable baseline data on production and consumption, and this is missing. Similarly, there is little evidence of the proposed ‘Inclusive Market Oriented Development’ (IMOD) framework being used to assist with priority setting. The product lines, eight of which cover most of the historical programmes in place in the partner CGIAR centres at the commencement of the Grain Legumes, do not cover all the constraints for formal constraints analysis was not undertaken at the inception of the Grain Legumes, and some of this additionally identified research is undertaken under the umbrella of the FPs; this needs to be rationalised. We found the PLs to be isolated in activity, even with minimally-integrated activities within each PL, with little evidence of synergy between PLs. Even though the SCs should ensure a systems approach, as with the new FPs, we did not get a feel that this is so. The underplaying of agronomy, and production practices may be one reason for this. We believe that treating legume crops as if they were horticultural crops will increase farmer returns from investment. The choice of Flagship Projects makes sense, with the flow of activity firstly around crop management and agronomy followed by the logical sequence of trait discovery, incorporation into improved varieties, dissemination of those varieties through appropriate seed chains leading to market impacts, and the capacity building required at all steps. One obvious omission, however, is the lack of a central and strategic policy on the role of transgenics in Grain Legumes. We found four notable comparative advantages for Grain Legumes: the access to germplasm of component species, the use of the phenotyping facility at ICRISAT, the approach for village level industry for IPM, and the emphasis on hybrid pigeonpea. Efficiency Each centre has strong control of, and emphasis on, their ‘species’ domains, and ownership of the same detracts from possible synergy. Without synergy or value add, the Grain Legumes brings with it no comparative advantage over each centre continuing their own pre-CRP research agendas. We found little evidence of integration of programmes between centres and almost no cross-centre authorship of publications, such as could have occurred with the integrated cross-centre approaches to stress tolerance including crop modelling: the one publication (Gaur et al., 2015) on heat tolerance by ICRISAT, CIAT and ICARDA does not provide any keys to inter-centre collaboration. The integration of each centre with NARS and university research programmes is good, but the cross-centre links with NARS are poor. A better coordinated integration with Grain Legumes, , rather than through the individual centres, may reduce transactions costs for NARS, Monitoring and evaluation is, as noted throughout our report, one area of Grain Legumes research management that has not been given the attention it should have received. If it had have received proper attention, some of the issues of poor efficiency might have been nipped in the bud. A strong monitoring and evaluation system would have provided the baseline data and set the milestones that would have allowed both efficiency and effectiveness to be better appraised. We found no attempt to define comparative advantages of the CGIAR centres and their R4D activities, although practice showed the better grasp of CIAT in developing innovative seed distribution systems. During field visits and interviews, the CCEE Team observed shortcomings in the communication processes within Grain Legumes and with the broader scientific community and the public. For example, the public face of the program on the internet is out of date. Survey findings, however, suggest that information is shared freely and routinely within the PL within which scientists work. Some external issues, such as those with funding, low W1/W2 and poor sustainability of funding (especially if funding is top heavy with a few agencies), undermine research investment and confidence of partners in the system (e.g. as voiced by researchers working on crops and countries not included in TL III and the cessation of ongoing competitively-funded projects especially in India), but other issues attributable to the governance and management of the Grain Legumes, such as opaque integration of W3/bilaterals with W1/W2 funding require attention. Offsetting this, the existence of the Grain Legumes did mobilise additional funding [that it would not have if Grain Legumes did not exist]. We were concerned that Grain Legumes is simply not recognised outside of the CRP, with a limited www presence and centres promote themselves, rather than Grain Legumes (with exception in IITA). This is not a good move if one wishes to increase investment in the Grain Legumes. Although funding agencies require cost:benefit ratios, for example for each PL we faced difficulty in determining comparative value for money between investment in different types of research, and in being able to clearly attribute research and development outcomes to financial investment. There was also a time CCEE frame issue too. There is poor interaction with the private sector, notably in areas where they have a comparative financial advantage. We questioned in particular the apparent lack of interaction with the major agro-chemical companies, with respect to the development of herbicide tolerant (HT) grain legumes and the lack of evidence that the regulatory and trade aspects related to herbicide tolerant crops had been considered. Quality of science The quality of the science is highly variable across Grain Legumes, with pockets of real excellence that are linked to good levels of productivity, whereas other PLs are struggling to deliver quality publications, and outputs and outcomes that are based on these. There is much evidence of gradualism in terms of research output and outcomes, i.e. essentially the same activities that were ongoing at the time of the launch of Grain Legumes are still in place. However, there are examples of game changers including those from valuable investments in genomics, phenotyping, and bio-control. We were pleased to see large proportions of collaboration on publications with non-CGIAR centres, reflecting cooperation with partners in developed and developing countries. The value of collaboration when ensuring quality of science cannot be stressed highly enough both within the CRP, and with other global and national partners. PLs should be given incentives to collaborate with other CRPs and external institutions. There is little cohesion between PLs and with other CRPs as evidenced by publications, although there are some exceptions. We suspect the reasons for this are driven by funding. Productivity from the different PLs is also highly variable and it is not clear what other activities staff are engaged in since, in some PLs, they do not appear to lead to quality publications. Effectiveness Grain Legumes has been very effective in addressing component issues of research, but not the continuum from variety development to legumes on someone’s dinner plate. Our overall assessment of the effectiveness of Grain Legumes in stimulating synergy, innovation and impact indicate that gradualism is more prevalent than innovation. It also shows, as do publications, that there is little integration of disciplines or a focus on ‘systems’. The absence of socio-economists from research teams is evident in the general lack of an end user focus. However, research on genomics, plant breeding and seed systems have made great strides forward, on the brink of delivering impact. Agronomy has been a poor sister, but some of the competitive grants within Grain Legumes have unearthed some potential game changers, such as objective use of transplanting as an agronomic practice. As mentioned earlier, the lack of effective M&E (however, this was part of some major projects such as TL II/TL III), and therefore the ability to monitor impact pathways and achievement of impact, implies no systematic management of data. This creates difficulty when attempting to evaluate the achievement of the Grain Legumes objectives. One might have expected at least one attempt to try to develop publications between centres arguing for similar biologies/research approaches, bringing species together under one umbrella, but we did not find any evidence for this. It is most unfortunate that, due to budgetary cuts, the new ‘schemes’, e.g. competitive grants and scholarships, were cut off before gaining a foothold. With 8 species addressed by Grain Legumes, it is not unexpected that there will be little evidence of shared protocols across centres/species. One rare example was that hosted by the United States Department of Agriculture (USDA) on shared methods for phenotyping of legume germplasm. Researchers from CIAT, IITA, ICRISAT and three USDA stations attended, focusing in simple canopy temperature and root morphology measurements. It is our belief that as a set of research centres, the CGIAR centres should be focusing on the research for which they have a comparative advantage. While imposing the restructure to FPs, which is fine for development objectives and outcomes (funded through W3/bilateral), it is less so for a research institute, and the structure should not detract from the more basic work expected of an international CGIAR centre (or set of centres as in a CRP). Impact It is well known that research does not always lead to scientific breakthroughs. Also, activities such as plant breeding are long term; making impacts difficult to assess. We believe that sufficient progress with genomics and associated research has been made to warrant impact, but we are unable to quantify the levels of impact, or the timeframe for the same. Work in Grain Legumes has enormous potential for real impact in scientific research, commercial, farming, smallholder and household communities, much of which is being realised. However, the PLs need to become more adept at providing convincing cases that are strongly evidenced for these impacts, as this is likely to be a key factor in leveraging future funding. Claimed gains must be referenced against baseline data, and these are not always readily available. The CCEE Team realises that such impact evaluation represents a significant drain on resources, and Grain Legumes should determine whether the balance of costs to benefits favours such investment. Interviews conducted by the CCEE during site visits showed that PLs are quantifying the area of adoption of varieties, but in most cases they are not measuring the impact on environment, health/nutrition. Since the health and nutritional benefits and the environmental gains from growing legumes are major arguments for supporting grain legume research, the community is currently missing substantial opportunities to strengthen its own case for continued support. Whilst there are some impressive examples of considering the whole value chain, e.g. white beans from production through to export; in the main, the pipeline to end user is somewhat piece-meal, with no clear definition of the end user nor differential responsibility of Grain Legumes and of partners. The lack of robust time-defined impact pathways is highlighted in Section 7.4, and even though developed for PL5, timeframes are essential for measuring progress against prediction. Sustainability In summary, there is general acknowledgement that future funding is likely to become more limited, specifically in W1&2 and there is understandable concern over the support for the staff and basic infrastructure that underpin the Grain Legumes programme. For example, it is reported that staffing in parts of CIAT has been dependent on W1&2 and that this is too unstable to re-establish a critical mass. The present system whereby W3 and bilateral projects do not pay a realistic level of overheads means that such projects are being effectively subsidised by W1&2. This position is not sustainable in the long term as there will be a progressive but definite loss of basic skills and resources in the core centres. The only obvious options to prevent this outcome include a severe reduction in the fixed costs of the centres and/or a refusal to accept W3 and bilateral funding with an inadequate overhead component. In the latter case, there is an obvious danger that funders will move their resources away from the CGIAR system towards other, perhaps less expensive, suppliers of research, and possibly more relevant development expertise. This issue must be addressed. As the Grain Legumes moves into the future, and if sustainable funding cannot be assured, decisions must be made concerning a reduction in activities, keeping some caretaker breeding maintenance, and focus (as has TL III) on fewer species and a reduced geographic focus. Cross cutting issues: Gender, capacity building and partnerships Gender is not mainstreamed, but there is some evidence that this is improving, especially with dedicated gender specialists and the slow integration of gender across CRPs. There is a need to approach gender through the vision of agriculture as a social practice, with recognition of what changes will be acceptable culturally and what not, and capitalising upon the perceived and actual features of production and processing that grain legumes are primarily women-based crops. Gender awareness may be high among Scientists, but it appears to be a predominantly passive attribute with few proactively seeking opportunities for gender equity. It is, however, a sound sensitivity base on which to build. Nevertheless, examples of notable gender initiatives were identified during field visits. For example, in Benin, the development of biocontrol technologies has enthusiastically integrated diversity, engaging with women farmers’ and youths while maintaining cultural norms. Women are gathering and processing, youths are taking the product to market. The implication is that several groups benefit, rather than domination by the majority group. In Malawi, innovative approaches have been developed to improving nutrition for children, such as incorporating nutrient enriched bean flour products into snacks. In India, scientists collaborating with gender scientists and socio-economists are identifying the impact of mechanical harvesting on agricultural labour and the potential displacement of female labourers. In Kenya, a novel initiative is improving the accessibility of certified seed for new varieties. Seed suppliers have introduced small packs of grain legume seed at low unit cost, which are being purchased by young people and women. Capacity building efforts for external partners are not clearly aligned with the research mandate and delivery of Grain Legumes. However, there are a number of training activities that are being undertaken by Grain Legumes, largely through the W3/bilateral project. Gender balance never reaches parity, but it appears that efforts are made to include female participants. Within the evaluation timeframe it was not possible to conduct external surveys to further validate or review external capacity building efforts in Grain Legumes. Training of scientists is significant, with >40 benefiting. Postgraduate training is varied across PLs, and there is some opportunity to increase the numbers being supervised. We consider that support for postgraduates at ICRISAT could be better coordinated, satisfying more of the students’ needs. It is important, however, to follow up investments in capacity building by monitoring effectiveness, career progressions and so on. Training activities appear to be rather centre-specific, not following a coordinated programme managed by, nor at the level of, the Grain Legumes. Numbers of persons trained and their gender are important, but a measure of the effectiveness of the training is more important. Although optimism is expressed by the great majority of Research Managers that partnerships were working well to leverage knowledge and research capacities, scientists have a less favourable view, particularly in terms of their incentives to participate. It seems likely that the activities taking place within Grain Legumes were, in the most part, continuations of previous collaborations. This is not surprising in light of the reduction in the emphasis on partnerships as Grain Legumes evolved to a funded project, and the consequent lack of opportunity and ambition for establishing novel partnerships. Where they exist, partnerships are good on the whole, especially with US. They could be expanded where comparative advantages exist (for example with Canada and Australia for machine harvestable legumes), but some earlier identified partnerships, e.g. with Turkey, have not been capitalised upon. Others experience problems of variety access (the embargo on exports of some sources of materials from India), yet others do have relevance e.g. imported Brazilian varieties in pre-release in Ethiopia (even though two of the three are from CIAT materials). Governance and Management The standard format of committee structure and responsibilities is common to other CRPs, as are the attendant problems. One of the major problems is that the Grain Legumes Director has responsibility but no authority; hence, even with the support of the RMC, the Director is unable to ‘direct’ in the literal sense of the work the activities of Grain Legumes. We also see the same sense of helplessness with the role of the PLCs. They have responsibility but no authority in managing the affairs of their PL, and they have no access to funds with which to promote intellectual collaboration and cooperation. Minutes from governance and management meetings do not reflect the compromised weak position of the Director and the associated difficulties in the management of Grain Legumes. Nor do the minutes reflect concerns about the amount of time spent by scientists in meetings for planning, integration, evaluation and reporting. Many scientists reported significant opportunity costs in participating in the ongoing imposed [by the CO] evolution of Grain Legumes and CRPs in general. The changes brought in by the CO have not helped promote any greater authority and capacity of the Grain Legumes Director to direct. Likewise, they do not address any of the issues with the conflict of interest in having the Lead Centre chair the Steering Committee. Indeed, we believe that the combining of the Steering Committee with the Independent Advisory Committee, besides becoming unwieldy in number, annuls any sense of independence in advice offered to the Grain Legumes management. We have concerns with the declining proportion of W1/W2 funds (as expressed in the section on Sustainability), and believe that when basic financial planning takes place, integration of W1/W2 and W3/bilateral sources must occur, and be linked to anticipated outcomes and impacts. This will ensure a close alignment of collaborators’ and partners’ objectives and contributions to that of the Grain Legumes. We also queried the process for, and the formality, or lack of, surrounding, the approval of annual budgets, and the level of priority setting when budgets are cut. Recommendations for Grain Legumes The CCEE Team makes the following recommendations, critical issues are highlighted in bold, and those that require action by an entity other than the Grain Legumes Research Management Committee or Project Management united are identified in a footnote. Relevance and Strategy Recommendation 1: A period of consistency is necessary to raise confidence, morale and trust across scientists, managers and partners to foster the assembly of enduring Grain Legumes outcomes2.  There needs to be a concerted effort to undertake baseline studies and to implement a robust M&E activity during this period. Without these data the foundation for integrated research in grain legumes is jeopardised.  There is a strong need to link more closely with the private sector, especially where there are financial and other comparative advantages to do so. Recommendation 2: The agronomic and physiological trait targets of Grain Legumes (tolerance to changing climate patterns, to the pests and diseases of today and of the future, incorporation of quality traits and adaptations to intensive production systems [machine-harvestability and herbicide tolerance], and short season high yielding characters) are all worthy of continued investment when selecting for improved varieties.  There needs to be a common strategy, implemented across centres and species, as to how to address these trait targets through conventional and modern breeding approaches, but only if adequate funding is assured and secured and if a consistency and unity of purpose can be achieved across a large-scale. This should take the form of cross-species coordinated research programmes to address these breeding targets that cooperate across centres and make efficient use of facilities and other resources.  The CRP should undertake a detailed strategic review of the role of transgenics across the range of targets in the mandate crops. Efficiency Recommendation 3: The lack of an effective M&E process is a significant omission, not least in terms of more efficient use of resources and the lack of baseline data with which to measure impact, and must be rectified.  Reinforcing Recommendation 1, an effective M&E system initially directed towards baseline studies must be implemented.  Transaction costs may be reduced through bilateral projects, which are seen as more cost effective than W1/W2 where transaction costs are disproportionately higher. Recommendation 4: To improve communication and coordination within the CRP, and with a broader audience:  There is a priority need for a central database containing, names of staff associated with Grain Legumes and their time commitments, their responsibilities, and involvement in CRP activities, their progress and achievements, their publications, plans of training, travel, and other opportunities for interaction.  Regular global meetings of staff involved in managing PLs, the entire CRP management staff and the IAC are essential for effective coordination of all activity within Grain Legumes.  The website must be given a complete overhaul and improvement and then regular maintenance must be provided to keep it current. Quality of Science Recommendation 5: It is essential to continue investment in good science and to institute a change from gradualism in research output and outcomes to an expectation of innovative and concrete achievements that can be attributed clearly to people, centres and core facilities.  A cost:benefit analysis and subsequent strategic planning must be undertaken to justify further investment in the genomics and phenotyping facilities at ICRISAT especially as such technologies advance rapidly. Strategic planning and coordination must also be implemented for capitalising on the investment in crop simulation modelling. (The phenotyping facility of ICRISAT needs to focus on delivering some outcomes, not only outputs.)  PLs should be given incentives to collaborate with other CRPs and external institutions. The CCEE recommends special recognition of high quality collaborative papers, thereby encouraging increased quality of the research programmes and widening the penetration of research impacts.  More importance should be placed on the quality of publication, rather than quantity of outputs and there should be recognition of other types of outputs from Grain Legumes. The CRP Director must be party to this.  If staff are engaged in activities that relate more to impact than publication then this needs to be monitored and recorded and a clearer understanding developed of what constitutes a pathway to impact and how success of such activities can be evaluated. A system must be devised and incorporated into the M&E to enable recognition of other types of outputs (non- publication based) from Grain Legumes, e.g. varieties for breeders. Effectiveness Recommendation 6: To develop greater synergy, Grain Legumes should review management processes and the direction of research activities. In particular, far more extensive integration of research and knowledge exchange should take place across both African and Asian continents so that the best aspects of both can be shared. A multidisciplinary approach is recommended that considers processing solutions, as well as breeding solutions, to capitalise upon the nutritional benefits of the grain legume crops. We recommend:  A better collaboration with social scientists at the design stage of experiments in order to improve the utility of the work carried out and to understand its reach.  Supporting3 the adoption of best practice electronic data collection, central storage and open access, particularly of genomic data, for public use.  Given the focus on the link between phenotyping and genotyping, we note that there is a lack of congruence between the populations that are being phenotyped and those being genotyped, and therefore these could be better aligned within each species.  Concentrating investment external to Grain Legumes on scaling up production of varieties with the most promising trait profiles to meet the basic seed requirement.  Developing a more holistic approach that coordinates an understanding of the disease pathology and epidemiology, and of new chemicals before they become commercially available, together with agronomic practice such that recommendations can be made for growers. Continuing work to establish whether agronomic factors hold true in different environments and to assess GxE effects within breeding programmes. Such rigorous trial practices should be used to inform the evaluation of breeding lines and to provide phenotype data to associate with markers for traits such as heat, drought and herbicide tolerance.  Considering grain legumes as if they were vegetable crops in terms of the strategy for intensification of production, both from the management perspective and for seed systems, will be a useful development objective into the future. This will bring about more rapid intensification and is likely to increase farmer returns from investment. Recommendation 7: The CGIAR centres should focus in on the research for which they have a comparative advantage. While imposing the restructure to FPs, which is fine for development objectives and outcomes (funded through W3/bilateral) it is less so for a research institute, and should not detract from the more basic work expected of an international CGIAR centre (or set of centres in a CRP).  Collaborative approaches should be explored within Grain Legumes, e.g. similar biologies/research approaches, bringing species together under one umbrella. Similarly better alignment is needed to address the lack of congruence between the populations that are being phenotyped and those being genotyped.  Despite positive impacts from research in genomics, plant breeding and seed systems, the lack of an effective M&E, already mentioned elsewhere, has reduced the ability to monitor impact pathways. This must be addressed.  The absence of socio-economists from research teams is evident in the general lack of an end user focus. Responsibilities of the different actors in the whole value chain must be considered and identified when developing impact targets, and the pathway leading to them, for individual projects. People with socio-economist skills must be part of the team from project inception so that appropriate frameworks are incorporated for measuring and influencing sociological and economic changes brought about by Grain Legumes research. Impact Recommendation 8: PLs need to become more adept at providing convincing cases in which impact is strongly evidenced, as this is likely to be a key factor in leveraging future funding.  Claimed gains must be referenced against baseline data, and these are not always readily available. The CCEE Team realises that such impact evaluation represents a significant drain on resources, and Grain Legumes should determine whether the balance of costs to benefits favours such investment.  It is essential that Grain Legumes provides training to staff on what constitutes impact and how it can be recorded.  Specific, rather than generalised, potential impacts arising from activity within Grain Legumes should be defined at the time of justifying the programme of work and a pathway to impact should form part of the documentation prepared ahead of a piece of research commencing. . In other words, centres should submit work plans to Grain Legumes before they are undertaken using W1/W2 funds Recommendation 9: The reporting activity must be streamlined to a single (brief) format that can be used to report to Grain Legumes, Centres and to donors for special project activities4. Sustainability Recommendation 10: As Grain Legumes moves into the future, and if sustainable funding cannot be assured, decisions must be made concerning a reduction in activities, keeping some caretaker breeding maintenance, and focus (as has TL III) on fewer species and a reduced geographic focus. Zeigler (Director General of IRRI) states “…time and effort would be better spent … making tough decisions about which programs deserve the precious support.”  The present system whereby W3 and bilateral projects do not pay a realistic level of overheads means that such projects are being effectively subsidised by W1&2 and there will be a progressive but definite loss of basic skills and resources in the core centres. To prevent this outcome it is necessary to significantly reduce the fixed costs of the centres and/or refuse to accept W3 and bilateral funding without an adequate overhead component.  In the absence of long term certainty, the scale of the budget allocated to each of the new CRPs should be very conservative, a feature that can only be achieved by restricting/reducing the scope, probably quite significantly. Cross cutting issues: Gender, capacity building and partnerships Recommendation 11: The challenge for Grain Legumes is to achieve pro-active gender mainstreaming, which facilitates opportunities for gender diversity within all activities, from employment processes through research to end users.  Strategic measurable gender indicators need to be embedded in research design, for instance, through specific IDOs for each of the flagships projects. Accurate baseline data are also required to facilitate M&E reviews of progress.  Implementation of the Gender Strategy is the responsibility of everyone, not solely the Gender Team. Thus, ownership could be encouraged by setting personal development for key personnel objectives with specific outcomes, e.g. employment practices or research outcomes.  Recognising the positive gender initiatives in progress or planned, feedback must be communicated and integrated into broader research planning to share opportunities, methods and outcomes.  In addition to promoting gender equity in research, Grain Legumes also needs to ensure that working environments are gender sensitive and that recruitment processes, including promotion opportunities are equitable. Gender imbalance in management should be actively examined to identify further opportunities for developing female leadership. Recommendation 12: It is recommended that a training plan be devised to ensure that capacity building efforts are more clearly aligned with the research mandate, delivery and timeframe of Grain Legumes. Moreover, we recommend that ICRISAT develop a strategy to treat their new cohort of researchers more equitably in the future. Recommendation 13: To develop a more coherent strategic programme designed to eliminate overlap and promote synergy between programmes with common aims, Grain Legumes should hold a meeting with a range of partners. Governance Recommendation 14: Governance processes should be re-assessed and the structure altered to ensure that the Grain Legumes Director has the authority and budget control to drive the execution of strategy.  The ISC should be truly independent and given the power to influence strategic decisions before they become final. We also recommend that PLCs are provided with the authority to manage the direction and finances of their PL; and that ring-fenced funds are provided for the promotion of collaboration, coordination and staff training5. The way ahead In our view, having seen the ineffectiveness of much of the attempts [or lack of attempts] to harness synergies between multiple centres, and of the strength in few or sole centre partnerships, we believe that there is little to justify a full retention of the 8 legume species and 4 CGIAR centres in a CRP. TL I and II and PABRA have shown to be reasonably good cross-centre and single centre integrated programmes, but even they suffer from incomplete value chain approaches to increasing rural incomes while increasing food and nutritional security; they both need multi-faceted solutions which are not immediately forthcoming from Grain Legumes. It is important to embed Grain Legumes research within the agri-food systems these crops serve. Figure ES1 broadly shows the perceived current and potential degrees of synergy between centres, PLs and species, and is discussed more in the text. It is clear that the value chains for individual species from trait determination to nutritional impact have more cohesion than do the individual activities (e.g. trait deployment) across species. For this reason we believe that the future for research in Grain Legumes is best addressed by focusing on each of the species separately, and within an ecosystem framework; any synergy for research across species can be effected through communication and not necessarily through obligatory cooperative research. The ecosystem framework will allow for strengthening of agronomy type systems research, the arguments for benefits of inclusion of grain legumes in cropping systems, which is notable by its absence in much of what Grain Legumes currently undertakes. Figure ES1. Current and potential degrees of synergy between centres, PLs and crop species We therefore agree with the innovation in agri-food systems approach of the CG, and believe that Grain Legumes rightly belongs in the Dryland Cereals and Legumes Agri-food Systems. We believe that the option of combining the crops of dryland cereals and legumes in the cereal-legume-livestock systems of subsistence farming communities for whole-farm productivity is closest to the best way forward. Indeed the inclusion of grain legumes may not warrant even a CRP alone, rather the legume components should fit in with the major crops that determine the production systems. Legumes will always be subservient to the major cereals, as necessary adjuncts to the whole production system, providing both nutritional diversity and environmental services, neither achievable from cereals alone. Figure ES2. Most suitable option for integration of Grain Legumes and Dryland Cereals into an Agri-Food Systems CRP Most suitable option for integration of Grain Legumes and Dryland Cereals into an Agri-Food Systems CRP, which  Incorporates ex-Dryland Systems, Dryland Cereals, Grain Legumes, some HumidTropics, some ex-Livestock &Fisheries into a new CRP  Will cover full agri-food system VC for all 8 legumes in all ecologies, but must interact (dock) with the relevant AFS-CRPs for the dominant cereal in the relevant ecology  Hence, will need to negotiate with other Agrifood Systems-CRPs on who does what for legumes  In addition, responsible for sorghum and millet in the mixed dryland crop-livestock agro-ecologies For major game changers to be effected, we believe that the game has to change, and there is little evidence of this. The direction of CRPs is the correct route, but the journey has not yet come to its destination. A major change of game [such as the adoption of a Flagship Project approach as exemplified by the Australian CSIRO – where flagships contract services from centres of research excellence] would be painful to implant. The CGIAR system is going down the right pathway but it has not gone far enough.

Molecular modeling databases: A new way in the search of protein targets for drug development

DBMODELING is a relational database of annotated comparative protein structure models and their metabolic, pathway characterization. It is focused on enzymes identified in the genomes of Mycobacterium tuberculosis and Xylella fastidiosa. The main goal of the present database is to provide structural models to be used in docking simulations and drug design. However, since the accuracy of structural models is highly dependent on sequence identity between template and target, it is necessary to make clear to the user that only models which show high structural quality should be used in such efforts. Molecular modeling of these genomes generated a database, in which all structural models were built using alignments presenting more than 30% of sequence identity, generating models with medium and high accuracy. All models in the database are publicly accessible at http://www.biocristalografia.df.ibilce.unesp.br/tools. DBMODELING user interface provides users friendly menus, so that all information can be printed in one stop from any web browser. Furthermore, DBMODELING also provides a docking interface, which allows the user to carry out geometric docking simulation, against the molecular models available in the database. There are three other important homology model databases: MODBASE, SWISSMODEL, and GTOP. The main applications of these databases are described in the present article. © 2007 Bentham Science Publishers Ltd.

Le cure oncologiche e la prospettiva del paziente. Revisione di letteratura e un caso di studio

Numerose ricerche indicano i modelli di cure integrate come la migliore soluzione per costruire un sistema più efficace ed efficiente nella risposta ai bisogni del paziente con tumore, spesso, però, l’integrazione è considerata da una prospettiva principalmente clinica, come l’adozione di linee guida nei percorsi della diagnosi e del trattamento assistenziale o la promozione di gruppi di lavoro per specifiche patologie, trascurando la prospettiva del paziente e la valutazione della sua esperienza nei servizi. Il presente lavoro si propone di esaminare la relazione tra l’integrazione delle cure oncologiche e l’esperienza del paziente; com'è rappresentato il suo coinvolgimento e quali siano i campi di partecipazione nel percorso oncologico, infine se sia possibile misurare l’esperienza vissuta. L’indagine è stata svolta sia attraverso la revisione e l’analisi della letteratura sia attraverso un caso di studio, condotto all'interno della Rete Oncologica di Area Vasta Romagna, tramite la somministrazione di un questionario a 310 pazienti con neoplasia al colon retto o alla mammella. Dai risultati, emerge un quadro generale positivo della relazione tra l’organizzazione a rete dei servizi oncologici e l’esperienza del paziente. In particolare, è stato possibile evidenziare quattro principali nodi organizzativi che introducono la prospettiva del paziente: “individual care provider”,“team care provider”,“mixed approach”,“continuity and quality of care”. Inoltre, è stato possibile delineare un campo semantico coerente del concetto di coinvolgimento del paziente in oncologia e individuare quattro campi di applicazione, lungo tutte le fasi del percorso: “prevenzione”, “trattamento”,“cura”,“ricerca”. Infine, è stato possibile identificare nel concetto di continuità di cura il modo in cui i singoli pazienti sperimentano l’integrazione o il coordinamento delle cure e analizzare differenti aspetti del vissuto della persona e dell’organizzazione.

Integration of a simulation platform for electrical mobility within the arrowhead interoperability framework

This dissertation document deals with the development of a project, over a span of more than two years, carried out within the scope of the Arrowhead Framework and which bears my personal contribution in several sections. The final part of the project took place during a visiting period at the university of Luleå. The Arrowhead Project is an European project, belonging to the ARTEMIS association, which aims to foster new technologies and unify the access to them into an unique framework. Such technologies include the Internet of Things phe- nomenon, Smart Houses, Electrical Mobility and renewable energy production. An application is considered compliant with such framework when it respects the Service Oriented Architecture paradigm and it is able to interact with a set of defined components called Arrowhead Core Services. My personal contribution to this project is given by the development of several user-friendly API, published in the project's main repository, and the integration of a legacy system within the Arrowhead Framework. The implementation of this legacy system was initiated by me in 2012 and, after many improvements carried out by several developers in UniBO, it has been again significantly modified this year in order to achieve compatibility. The system consists of a simulation of an urban scenario where a certain amount of electrical vehicles are traveling along their specified routes. The vehicles are con-suming their battery and, thus, need to recharge at the charging stations. The electrical vehicles need to use a reservation mechanism to be able to recharge and avoid waiting lines, due to the long recharge process. The integration with the above mentioned framework consists in the publication of the services that the system provides to the end users through the instantiation of several Arrowhead Service Producers, together with a demo Arrowhead- compliant client application able to consume such services.

Pinocchio: Bringing Reflection to Life with First-Class Interpreters

To support development tools like debuggers, runtime systems need to provide a meta-programming interface to alter their semantics and access internal data. Reflective capabilities are typically fixed by the Virtual Machine (VM). Unanticipated reflective features must either be simulated by complex program transformations, or they require the development of a specially tailored VM. We propose a novel approach to behavioral reflection that eliminates the barrier between applications and the VM by manipulating an explicit tower of first-class interpreters. Pinocchio is a proof-of-concept implementation of our approach which enables radical changes to the interpretation of programs by explicitly instantiating subclasses of the base interpreter. We illustrate the design of Pinocchio through non-trivial examples that extend runtime semantics to support debugging, parallel debugging, and back-in-time object-flow debugging. Although performance is not yet addressed, we also discuss numerous opportunities for optimization, which we believe will lead to a practical approach to behavioral reflection.

Copyright, Interfaces, and a Possible Atlantic Divide

Recent copyright cases on both sides of the Atlantic focused on important interoperability issues. While the decision by the Court of Justice of the European Union in SAS Institute, Inc.v. World Programming Ltd. assessed data formats under the EU Software Directive, the ruling by the Northern District of California Court in Oracle America, Inc. v. Google Inc. dealt with application programming interfaces. The European decision is rightly celebrated as a further important step in the promotion of interoperability in the EU. This article argues that, despite appreciable signs of convergence across the Atlantic, the assessment of application programming interfaces under EU law could still turn out to be quite different, and arguably much less pro-interoperability, than under U.S. law.

Side-Channel Attack Protection Techniques in FPGA Systems using Enhanced Dual-Rail Solutions

Esta tesis doctoral se centra principalmente en técnicas de ataque y contramedidas relacionadas con ataques de canal lateral (SCA por sus siglas en inglés), que han sido propuestas dentro del campo de investigación académica desde hace 17 años. Las investigaciones relacionadas han experimentado un notable crecimiento en las últimas décadas, mientras que los diseños enfocados en la protección sólida y eficaz contra dichos ataques aún se mantienen como un tema de investigación abierto, en el que se necesitan iniciativas más confiables para la protección de la información persona de empresa y de datos nacionales. El primer uso documentado de codificación secreta se remonta a alrededor de 1700 B.C., cuando los jeroglíficos del antiguo Egipto eran descritos en las inscripciones. La seguridad de la información siempre ha supuesto un factor clave en la transmisión de datos relacionados con inteligencia diplomática o militar. Debido a la evolución rápida de las técnicas modernas de comunicación, soluciones de cifrado se incorporaron por primera vez para garantizar la seguridad, integridad y confidencialidad de los contextos de transmisión a través de cables sin seguridad o medios inalámbricos. Debido a las restricciones de potencia de cálculo antes de la era del ordenador, la técnica de cifrado simple era un método más que suficiente para ocultar la información. Sin embargo, algunas vulnerabilidades algorítmicas pueden ser explotadas para restaurar la regla de codificación sin mucho esfuerzo. Esto ha motivado nuevas investigaciones en el área de la criptografía, con el fin de proteger el sistema de información ante sofisticados algoritmos. Con la invención de los ordenadores se ha acelerado en gran medida la implementación de criptografía segura, que ofrece resistencia eficiente encaminada a obtener mayores capacidades de computación altamente reforzadas. Igualmente, sofisticados cripto-análisis han impulsado las tecnologías de computación. Hoy en día, el mundo de la información ha estado involucrado con el campo de la criptografía, enfocada a proteger cualquier campo a través de diversas soluciones de cifrado. Estos enfoques se han fortalecido debido a la unificación optimizada de teorías matemáticas modernas y prácticas eficaces de hardware, siendo posible su implementación en varias plataformas (microprocesador, ASIC, FPGA, etc.). Las necesidades y requisitos de seguridad en la industria son las principales métricas de conducción en el diseño electrónico, con el objetivo de promover la fabricación de productos de gran alcance sin sacrificar la seguridad de los clientes. Sin embargo, una vulnerabilidad en la implementación práctica encontrada por el Prof. Paul Kocher, et al en 1996 implica que un circuito digital es inherentemente vulnerable a un ataque no convencional, lo cual fue nombrado posteriormente como ataque de canal lateral, debido a su fuente de análisis. Sin embargo, algunas críticas sobre los algoritmos criptográficos teóricamente seguros surgieron casi inmediatamente después de este descubrimiento. En este sentido, los circuitos digitales consisten típicamente en un gran número de celdas lógicas fundamentales (como MOS - Metal Oxide Semiconductor), construido sobre un sustrato de silicio durante la fabricación. La lógica de los circuitos se realiza en función de las innumerables conmutaciones de estas células. Este mecanismo provoca inevitablemente cierta emanación física especial que puede ser medida y correlacionada con el comportamiento interno del circuito. SCA se puede utilizar para revelar datos confidenciales (por ejemplo, la criptografía de claves), analizar la arquitectura lógica, el tiempo e incluso inyectar fallos malintencionados a los circuitos que se implementan en sistemas embebidos, como FPGAs, ASICs, o tarjetas inteligentes. Mediante el uso de la comparación de correlación entre la cantidad de fuga estimada y las fugas medidas de forma real, información confidencial puede ser reconstruida en mucho menos tiempo y computación. Para ser precisos, SCA básicamente cubre una amplia gama de tipos de ataques, como los análisis de consumo de energía y radiación ElectroMagnética (EM). Ambos se basan en análisis estadístico y, por lo tanto, requieren numerosas muestras. Los algoritmos de cifrado no están intrínsecamente preparados para ser resistentes ante SCA. Es por ello que se hace necesario durante la implementación de circuitos integrar medidas que permitan camuflar las fugas a través de "canales laterales". Las medidas contra SCA están evolucionando junto con el desarrollo de nuevas técnicas de ataque, así como la continua mejora de los dispositivos electrónicos. Las características físicas requieren contramedidas sobre la capa física, que generalmente se pueden clasificar en soluciones intrínsecas y extrínsecas. Contramedidas extrínsecas se ejecutan para confundir la fuente de ataque mediante la integración de ruido o mala alineación de la actividad interna. Comparativamente, las contramedidas intrínsecas están integradas en el propio algoritmo, para modificar la aplicación con el fin de minimizar las fugas medibles, o incluso hacer que dichas fugas no puedan ser medibles. Ocultación y Enmascaramiento son dos técnicas típicas incluidas en esta categoría. Concretamente, el enmascaramiento se aplica a nivel algorítmico, para alterar los datos intermedios sensibles con una máscara de manera reversible. A diferencia del enmascaramiento lineal, las operaciones no lineales que ampliamente existen en criptografías modernas son difíciles de enmascarar. Dicho método de ocultación, que ha sido verificado como una solución efectiva, comprende principalmente la codificación en doble carril, que está ideado especialmente para aplanar o eliminar la fuga dependiente de dato en potencia o en EM. En esta tesis doctoral, además de la descripción de las metodologías de ataque, se han dedicado grandes esfuerzos sobre la estructura del prototipo de la lógica propuesta, con el fin de realizar investigaciones enfocadas a la seguridad sobre contramedidas de arquitectura a nivel lógico. Una característica de SCA reside en el formato de las fuentes de fugas. Un típico ataque de canal lateral se refiere al análisis basado en la potencia, donde la capacidad fundamental del transistor MOS y otras capacidades parásitas son las fuentes esenciales de fugas. Por lo tanto, una lógica robusta resistente a SCA debe eliminar o mitigar las fugas de estas micro-unidades, como las puertas lógicas básicas, los puertos I/O y las rutas. Las herramientas EDA proporcionadas por los vendedores manipulan la lógica desde un nivel más alto, en lugar de realizarlo desde el nivel de puerta, donde las fugas de canal lateral se manifiestan. Por lo tanto, las implementaciones clásicas apenas satisfacen estas necesidades e inevitablemente atrofian el prototipo. Por todo ello, la implementación de un esquema de diseño personalizado y flexible ha de ser tomado en cuenta. En esta tesis se presenta el diseño y la implementación de una lógica innovadora para contrarrestar SCA, en la que se abordan 3 aspectos fundamentales: I. Se basa en ocultar la estrategia sobre el circuito en doble carril a nivel de puerta para obtener dinámicamente el equilibrio de las fugas en las capas inferiores; II. Esta lógica explota las características de la arquitectura de las FPGAs, para reducir al mínimo el gasto de recursos en la implementación; III. Se apoya en un conjunto de herramientas asistentes personalizadas, incorporadas al flujo genérico de diseño sobre FPGAs, con el fin de manipular los circuitos de forma automática. El kit de herramientas de diseño automático es compatible con la lógica de doble carril propuesta, para facilitar la aplicación práctica sobre la familia de FPGA del fabricante Xilinx. En este sentido, la metodología y las herramientas son flexibles para ser extendido a una amplia gama de aplicaciones en las que se desean obtener restricciones mucho más rígidas y sofisticadas a nivel de puerta o rutado. En esta tesis se realiza un gran esfuerzo para facilitar el proceso de implementación y reparación de lógica de doble carril genérica. La viabilidad de las soluciones propuestas es validada mediante la selección de algoritmos criptográficos ampliamente utilizados, y su evaluación exhaustiva en comparación con soluciones anteriores. Todas las propuestas están respaldadas eficazmente a través de ataques experimentales con el fin de validar las ventajas de seguridad del sistema. El presente trabajo de investigación tiene la intención de cerrar la brecha entre las barreras de implementación y la aplicación efectiva de lógica de doble carril. En esencia, a lo largo de esta tesis se describirá un conjunto de herramientas de implementación para FPGAs que se han desarrollado para trabajar junto con el flujo de diseño genérico de las mismas, con el fin de lograr crear de forma innovadora la lógica de doble carril. Un nuevo enfoque en el ámbito de la seguridad en el cifrado se propone para obtener personalización, automatización y flexibilidad en el prototipo de circuito de bajo nivel con granularidad fina. Las principales contribuciones del presente trabajo de investigación se resumen brevemente a continuación: Lógica de Precharge Absorbed-DPL logic: El uso de la conversión de netlist para reservar LUTs libres para ejecutar la señal de precharge y Ex en una lógica DPL. Posicionamiento entrelazado Row-crossed con pares idénticos de rutado en redes de doble carril, lo que ayuda a aumentar la resistencia frente a la medición EM selectiva y mitigar los impactos de las variaciones de proceso. Ejecución personalizada y herramientas de conversión automática para la generación de redes idénticas para la lógica de doble carril propuesta. (a) Para detectar y reparar conflictos en las conexiones; (b) Detectar y reparar las rutas asimétricas. (c) Para ser utilizado en otras lógicas donde se requiere un control estricto de las interconexiones en aplicaciones basadas en Xilinx. Plataforma CPA de pruebas personalizadas para el análisis de EM y potencia, incluyendo la construcción de dicha plataforma, el método de medición y análisis de los ataques. Análisis de tiempos para cuantificar los niveles de seguridad. División de Seguridad en la conversión parcial de un sistema de cifrado complejo para reducir los costes de la protección. Prueba de concepto de un sistema de calefacción auto-adaptativo para mitigar los impactos eléctricos debido a la variación del proceso de silicio de manera dinámica. La presente tesis doctoral se encuentra organizada tal y como se detalla a continuación: En el capítulo 1 se abordan los fundamentos de los ataques de canal lateral, que abarca desde conceptos básicos de teoría de modelos de análisis, además de la implementación de la plataforma y la ejecución de los ataques. En el capítulo 2 se incluyen las estrategias de resistencia SCA contra los ataques de potencia diferencial y de EM. Además de ello, en este capítulo se propone una lógica en doble carril compacta y segura como contribución de gran relevancia, así como también se presentará la transformación lógica basada en un diseño a nivel de puerta. Por otra parte, en el Capítulo 3 se abordan los desafíos relacionados con la implementación de lógica en doble carril genérica. Así mismo, se describirá un flujo de diseño personalizado para resolver los problemas de aplicación junto con una herramienta de desarrollo automático de aplicaciones propuesta, para mitigar las barreras de diseño y facilitar los procesos. En el capítulo 4 se describe de forma detallada la elaboración e implementación de las herramientas propuestas. Por otra parte, la verificación y validaciones de seguridad de la lógica propuesta, así como un sofisticado experimento de verificación de la seguridad del rutado, se describen en el capítulo 5. Por último, un resumen de las conclusiones de la tesis y las perspectivas como líneas futuras se incluyen en el capítulo 6. Con el fin de profundizar en el contenido de la tesis doctoral, cada capítulo se describe de forma más detallada a continuación: En el capítulo 1 se introduce plataforma de implementación hardware además las teorías básicas de ataque de canal lateral, y contiene principalmente: (a) La arquitectura genérica y las características de la FPGA a utilizar, en particular la Xilinx Virtex-5; (b) El algoritmo de cifrado seleccionado (un módulo comercial Advanced Encryption Standard (AES)); (c) Los elementos esenciales de los métodos de canal lateral, que permiten revelar las fugas de disipación correlacionadas con los comportamientos internos; y el método para recuperar esta relación entre las fluctuaciones físicas en los rastros de canal lateral y los datos internos procesados; (d) Las configuraciones de las plataformas de pruebas de potencia / EM abarcadas dentro de la presente tesis. El contenido de esta tesis se amplia y profundiza a partir del capítulo 2, en el cual se abordan varios aspectos claves. En primer lugar, el principio de protección de la compensación dinámica de la lógica genérica de precarga de doble carril (Dual-rail Precharge Logic-DPL) se explica mediante la descripción de los elementos compensados a nivel de puerta. En segundo lugar, la lógica PA-DPL es propuesta como aportación original, detallando el protocolo de la lógica y un caso de aplicación. En tercer lugar, dos flujos de diseño personalizados se muestran para realizar la conversión de doble carril. Junto con ello, se aclaran las definiciones técnicas relacionadas con la manipulación por encima de la netlist a nivel de LUT. Finalmente, una breve discusión sobre el proceso global se aborda en la parte final del capítulo. El Capítulo 3 estudia los principales retos durante la implementación de DPLs en FPGAs. El nivel de seguridad de las soluciones de resistencia a SCA encontradas en el estado del arte se ha degenerado debido a las barreras de implantación a través de herramientas EDA convencionales. En el escenario de la arquitectura FPGA estudiada, se discuten los problemas de los formatos de doble carril, impactos parásitos, sesgo tecnológico y la viabilidad de implementación. De acuerdo con estas elaboraciones, se plantean dos problemas: Cómo implementar la lógica propuesta sin penalizar los niveles de seguridad, y cómo manipular un gran número de celdas y automatizar el proceso. El PA-DPL propuesto en el capítulo 2 se valida con una serie de iniciativas, desde características estructurales como doble carril entrelazado o redes de rutado clonadas, hasta los métodos de aplicación tales como las herramientas de personalización y automatización de EDA. Por otra parte, un sistema de calefacción auto-adaptativo es representado y aplicado a una lógica de doble núcleo, con el fin de ajustar alternativamente la temperatura local para equilibrar los impactos negativos de la variación del proceso durante la operación en tiempo real. El capítulo 4 se centra en los detalles de la implementación del kit de herramientas. Desarrollado sobre una API third-party, el kit de herramientas personalizado es capaz de manipular los elementos de la lógica de circuito post P&R ncd (una versión binaria ilegible del xdl) convertido al formato XDL Xilinx. El mecanismo y razón de ser del conjunto de instrumentos propuestos son cuidadosamente descritos, que cubre la detección de enrutamiento y los enfoques para la reparación. El conjunto de herramientas desarrollado tiene como objetivo lograr redes de enrutamiento estrictamente idénticos para la lógica de doble carril, tanto para posicionamiento separado como para el entrelazado. Este capítulo particularmente especifica las bases técnicas para apoyar las implementaciones en los dispositivos de Xilinx y su flexibilidad para ser utilizado sobre otras aplicaciones. El capítulo 5 se enfoca en la aplicación de los casos de estudio para la validación de los grados de seguridad de la lógica propuesta. Se discuten los problemas técnicos detallados durante la ejecución y algunas nuevas técnicas de implementación. (a) Se discute el impacto en el proceso de posicionamiento de la lógica utilizando el kit de herramientas propuesto.

ABSTRACT This PhD thesis mainly concentrates on countermeasure techniques related to the Side Channel Attack (SCA), which has been put forward to academic exploitations since 17 years ago. The related research has seen a remarkable growth in the past decades, while the design of solid and efficient protection still curiously remain as an open research topic where more reliable initiatives are required for personal information privacy, enterprise and national data protections. The earliest documented usage of secret code can be traced back to around 1700 B.C., when the hieroglyphs in ancient Egypt are scribed in inscriptions. Information security always gained serious attention from diplomatic or military intelligence transmission. Due to the rapid evolvement of modern communication technique, crypto solution was first incorporated by electronic signal to ensure the confidentiality, integrity, availability, authenticity and non-repudiation of the transmitted contexts over unsecure cable or wireless channels. Restricted to the computation power before computer era, simple encryption tricks were practically sufficient to conceal information. However, algorithmic vulnerabilities can be excavated to restore the encoding rules with affordable efforts. This fact motivated the development of modern cryptography, aiming at guarding information system by complex and advanced algorithms. The appearance of computers has greatly pushed forward the invention of robust cryptographies, which efficiently offers resistance relying on highly strengthened computing capabilities. Likewise, advanced cryptanalysis has greatly driven the computing technologies in turn. Nowadays, the information world has been involved into a crypto world, protecting any fields by pervasive crypto solutions. These approaches are strong because of the optimized mergence between modern mathematical theories and effective hardware practices, being capable of implement crypto theories into various platforms (microprocessor, ASIC, FPGA, etc). Security needs from industries are actually the major driving metrics in electronic design, aiming at promoting the construction of systems with high performance without sacrificing security. Yet a vulnerability in practical implementation found by Prof. Paul Kocher, et al in 1996 implies that modern digital circuits are inherently vulnerable to an unconventional attack approach, which was named as side-channel attack since then from its analysis source. Critical suspicions to theoretically sound modern crypto algorithms surfaced almost immediately after this discovery. To be specifically, digital circuits typically consist of a great number of essential logic elements (as MOS - Metal Oxide Semiconductor), built upon a silicon substrate during the fabrication. Circuit logic is realized relying on the countless switch actions of these cells. This mechanism inevitably results in featured physical emanation that can be properly measured and correlated with internal circuit behaviors. SCAs can be used to reveal the confidential data (e.g. crypto-key), analyze the logic architecture, timing and even inject malicious faults to the circuits that are implemented in hardware system, like FPGA, ASIC, smart Card. Using various comparison solutions between the predicted leakage quantity and the measured leakage, secrets can be reconstructed at much less expense of time and computation. To be precisely, SCA basically encloses a wide range of attack types, typically as the analyses of power consumption or electromagnetic (EM) radiation. Both of them rely on statistical analyses, and hence require a number of samples. The crypto algorithms are not intrinsically fortified with SCA-resistance. Because of the severity, much attention has to be taken into the implementation so as to assemble countermeasures to camouflage the leakages via "side channels". Countermeasures against SCA are evolving along with the development of attack techniques. The physical characteristics requires countermeasures over physical layer, which can be generally classified into intrinsic and extrinsic vectors. Extrinsic countermeasures are executed to confuse the attacker by integrating noise, misalignment to the intra activities. Comparatively, intrinsic countermeasures are built into the algorithm itself, to modify the implementation for minimizing the measurable leakage, or making them not sensitive any more. Hiding and Masking are two typical techniques in this category. Concretely, masking applies to the algorithmic level, to alter the sensitive intermediate values with a mask in reversible ways. Unlike the linear masking, non-linear operations that widely exist in modern cryptographies are difficult to be masked. Approved to be an effective counter solution, hiding method mainly mentions dual-rail logic, which is specially devised for flattening or removing the data-dependent leakage in power or EM signatures. In this thesis, apart from the context describing the attack methodologies, efforts have also been dedicated to logic prototype, to mount extensive security investigations to countermeasures on logic-level. A characteristic of SCA resides on the format of leak sources. Typical side-channel attack concerns the power based analysis, where the fundamental capacitance from MOS transistors and other parasitic capacitances are the essential leak sources. Hence, a robust SCA-resistant logic must eliminate or mitigate the leakages from these micro units, such as basic logic gates, I/O ports and routings. The vendor provided EDA tools manipulate the logic from a higher behavioral-level, rather than the lower gate-level where side-channel leakage is generated. So, the classical implementations barely satisfy these needs and inevitably stunt the prototype. In this case, a customized and flexible design scheme is appealing to be devised. This thesis profiles an innovative logic style to counter SCA, which mainly addresses three major aspects: I. The proposed logic is based on the hiding strategy over gate-level dual-rail style to dynamically overbalance side-channel leakage from lower circuit layer; II. This logic exploits architectural features of modern FPGAs, to minimize the implementation expenses; III. It is supported by a set of assistant custom tools, incorporated by the generic FPGA design flow, to have circuit manipulations in an automatic manner. The automatic design toolkit supports the proposed dual-rail logic, facilitating the practical implementation on Xilinx FPGA families. While the methodologies and the tools are flexible to be expanded to a wide range of applications where rigid and sophisticated gate- or routing- constraints are desired. In this thesis a great effort is done to streamline the implementation workflow of generic dual-rail logic. The feasibility of the proposed solutions is validated by selected and widely used crypto algorithm, for thorough and fair evaluation w.r.t. prior solutions. All the proposals are effectively verified by security experiments. The presented research work attempts to solve the implementation troubles. The essence that will be formalized along this thesis is that a customized execution toolkit for modern FPGA systems is developed to work together with the generic FPGA design flow for creating innovative dual-rail logic. A method in crypto security area is constructed to obtain customization, automation and flexibility in low-level circuit prototype with fine-granularity in intractable routings. Main contributions of the presented work are summarized next: Precharge Absorbed-DPL logic: Using the netlist conversion to reserve free LUT inputs to execute the Precharge and Ex signal in a dual-rail logic style. A row-crossed interleaved placement method with identical routing pairs in dual-rail networks, which helps to increase the resistance against selective EM measurement and mitigate the impacts from process variations. Customized execution and automatic transformation tools for producing identical networks for the proposed dual-rail logic. (a) To detect and repair the conflict nets; (b) To detect and repair the asymmetric nets. (c) To be used in other logics where strict network control is required in Xilinx scenario. Customized correlation analysis testbed for EM and power attacks, including the platform construction, measurement method and attack analysis. A timing analysis based method for quantifying the security grades. A methodology of security partitions of complex crypto systems for reducing the protection cost. A proof-of-concept self-adaptive heating system to mitigate electrical impacts over process variations in dynamic dual-rail compensation manner. The thesis chapters are organized as follows: Chapter 1 discusses the side-channel attack fundamentals, which covers from theoretic basics to analysis models, and further to platform setup and attack execution. Chapter 2 centers to SCA-resistant strategies against generic power and EM attacks. In this chapter, a major contribution, a compact and secure dual-rail logic style, will be originally proposed. The logic transformation based on bottom-layer design will be presented. Chapter 3 is scheduled to elaborate the implementation challenges of generic dual-rail styles. A customized design flow to solve the implementation problems will be described along with a self-developed automatic implementation toolkit, for mitigating the design barriers and facilitating the processes. Chapter 4 will originally elaborate the tool specifics and construction details. The implementation case studies and security validations for the proposed logic style, as well as a sophisticated routing verification experiment, will be described in Chapter 5. Finally, a summary of thesis conclusions and perspectives for future work are included in Chapter 5. To better exhibit the thesis contents, each chapter is further described next: Chapter 1 provides the introduction of hardware implementation testbed and side-channel attack fundamentals, and mainly contains: (a) The FPGA generic architecture and device features, particularly of Virtex-5 FPGA; (b) The selected crypto algorithm - a commercially and extensively used Advanced Encryption Standard (AES) module - is detailed; (c) The essentials of Side-Channel methods are profiled. It reveals the correlated dissipation leakage to the internal behaviors, and the method to recover this relationship between the physical fluctuations in side-channel traces and the intra processed data; (d) The setups of the power/EM testing platforms enclosed inside the thesis work are given. The content of this thesis is expanded and deepened from chapter 2, which is divided into several aspects. First, the protection principle of dynamic compensation of the generic dual-rail precharge logic is explained by describing the compensated gate-level elements. Second, the novel DPL is originally proposed by detailing the logic protocol and an implementation case study. Third, a couple of custom workflows are shown next for realizing the rail conversion. Meanwhile, the technical definitions that are about to be manipulated above LUT-level netlist are clarified. A brief discussion about the batched process is given in the final part. Chapter 3 studies the implementation challenges of DPLs in FPGAs. The security level of state-of-the-art SCA-resistant solutions are decreased due to the implementation barriers using conventional EDA tools. In the studied FPGA scenario, problems are discussed from dual-rail format, parasitic impact, technological bias and implementation feasibility. According to these elaborations, two problems arise: How to implement the proposed logic without crippling the security level; and How to manipulate a large number of cells and automate the transformation. The proposed PA-DPL in chapter 2 is legalized with a series of initiatives, from structures to implementation methods. Furthermore, a self-adaptive heating system is depicted and implemented to a dual-core logic, assumed to alternatively adjust local temperature for balancing the negative impacts from silicon technological biases on real-time. Chapter 4 centers to the toolkit system. Built upon a third-party Application Program Interface (API) library, the customized toolkit is able to manipulate the logic elements from post P&R circuit (an unreadable binary version of the xdl one) converted to Xilinx xdl format. The mechanism and rationale of the proposed toolkit are carefully convoyed, covering the routing detection and repairing approaches. The developed toolkit aims to achieve very strictly identical routing networks for dual-rail logic both for separate and interleaved placement. This chapter particularly specifies the technical essentials to support the implementations in Xilinx devices and the flexibility to be expanded to other applications. Chapter 5 focuses on the implementation of the case studies for validating the security grades of the proposed logic style from the proposed toolkit. Comprehensive implementation techniques are discussed. (a) The placement impacts using the proposed toolkit are discussed. Different execution schemes, considering the global optimization in security and cost, are verified with experiments so as to find the optimized placement and repair schemes; (b) Security validations are realized with correlation, timing methods; (c) A systematic method is applied to a BCDL structured module to validate the routing impact over security metric; (d) The preliminary results using the self-adaptive heating system over process variation is given; (e) A practical implementation of the proposed toolkit to a large design is introduced. Chapter 6 includes the general summary of the complete work presented inside this thesis. Finally, a brief perspective for the future work is drawn which might expand the potential utilization of the thesis contributions to a wider range of implementation domains beyond cryptography on FPGAs.
