Managing FOSS during development: preventive and curative approaches

Today, most software development teams use free and open source software (FOSS) components, because it increases the speed and the quality of the development. Many open source components are the de facto standard of their category. However, FOSS has licensing restrictions, and corporate organizations usually maintain a list of allowed and forbidden licenses. But how do you enforce this policy? How can you make sure that ALL files in your source depot, either belong to you, or fit your licensing policy? A first, preventive approach is to train and increase the awareness of the development team to these licensing issues. Depending on the size of the team, it may be costly but necessary. However, this does not ensure that a single individual will not commit a forbidden icon or library, and jeopardize the legal status of the whole release... if not the company, since software is becoming more and more a critical asset. Another approach is to verify what is included in the source repository, and check whether it belongs to the open-source world. This can be done on-the-fly, whenever a new file is added into the source depot. It can also be part of the release process, as a verification step before publishing the release. In both cases, there are some tools and databases to automate the detection process. We will present the various options regarding FOSS detection, how this process can be integrated in the "software factory", and how the results can be displayed in a usable and efficient way.

Forma Tarraconis: GIS aplicado a la arqueología urbana

Desde aquel incipiente interés renacentista del siglo XVI hasta la profesionalización de la arqueología en la actualidad, la ingente actividad realizada en Tarragona ha necesitado de formas de registrarla y organizarla, a fin de ser estudiada en el contexto diacrónico general de la ciudad. Esta tarea se ha visto favorecida en el último decenio del siglo pasado por la aparición y adopción de una herramienta informática que no fue diseñada específicamente para la Arqueología. El GIS o SIG, se ha convertido en un instrumento básico e indispensable para cualquier ciudad que tenga un mínimo bagaje patrimonial. Prueba de ello son las publicaciones de Cartas Arqueológicas obtenidas a partir de este software, o sin ir mucho más lejos, los trabajos presentados en este simposio. Presentamos a continuación la experiencia de Tarragona en la creación de un programa, bajo soporte GIS, para la gestión de la actividad arqueológica. Previamente contextualizaremos esta experiencia ya que es justa heredera de iniciativas individuales y de equipos y proyectos previos que trataron, con mucha menor suerte que no éxito, de organizar y poner orden en la maltrecha documentación arqueológica de nuestra ciudad. Describiremos posteriormente las funcionalidades básicas de este programa, su arquitectura y las aplicaciones realizadas en el desarrollo de sendos proyectos de estudio de la ciudad. En este último caso nos centraremos, principalmente, en el proyecto Planimetria Arqueològica de Tàrraco, impulsado por el Museu d’Història del Ayuntamiento de Tarragona y el Institut Català d’Arqueologia Clàssica, y que ha contado con la colaboración de la Generalitat de Catalunya para su edición. Seguidamente veremos como el uso de la información en capas registrada en el GIS combinada con la inclusión de la cartografía histórica de una ciudad permiten el análisis de problemas arqueológicos irresolubles sólo con los datos estrictamente arqueológicos. En este caso se aplicará sobre la validación de la morfología urbana de Tarraco propuesta por Macias (2000a). Por último se hará una reflexión sobre cuales podrían ser las mejoras aplicables sobre el programa, en previsión de futuras revisiones del mismo.

INDISIM-YEAST, an individual-based model to study yeast

INDISIM-YEAST, an individual-based simulator, models the evolution of a yeast population by settingup rules of behaviour for each individual cell according to their own biological rules and characteristics. Ittakes into account the uptake, metabolism, budding reproduction and viability of the yeast cells, over aperiod of time in the bulk of a liquid medium, occupying a three dimensional closed spatial grid with twokinds of particles (glucose and ethanol). Each microorganism is characterized by its biomass, genealogicalage, states in the budding cellular reproduction cycle and position in the space among others. Simulationsare carried out for population properties (global properties), as well as for those properties that pertain toindividual yeast cells (microscopic properties). The results of the simulations are in good qualitativeagreement with established experimental trends.

Séquelles radio-induites et tests prédictifs [Radiation-induced sequelae: toward an individual profile]

The impact of curative radiotherapy depends mainly on the total dose delivered homogenously in the targeted volume. Nevertheless, the dose delivery is limited by the tolerated dose of the surrounding healthy tissues. Two different side effects (acute and late) can occur during and after radiotherapy. Of particular interest are the radiation-induced sequelae due to their irreversibility and the potential impact on daily quality of life. In a population treated in one center with the same technique, it appears that individual radiosensitivity clearly exists. In the hypothesis that genetic is involved in this area of research, lymphocytes seem to be the tissue of choice due to easy accessibility. Recently, low percentage of CD4 and CD8 lymphocyte apoptosis were shown to be correlated with high grade of sequelae. In addition, recent data suggest that patients with severe radiation-induced late side effects possess four or more SNP in candidate genes (ATM, SOD2, TGFB1, XRCC1 et XRCC3) and low radiation-induced CD8 lymphocyte apoptosis in vitro.

Thyroid antibody status, subclinical hypothyroidism, and the risk of coronary heart disease: an individual participant data analysis.

CONTEXT: Subclinical hypothyroidism has been associated with increased risk of coronary heart disease (CHD), particularly with thyrotropin levels of 10.0 mIU/L or greater. The measurement of thyroid antibodies helps predict the progression to overt hypothyroidism, but it is unclear whether thyroid autoimmunity independently affects CHD risk. OBJECTIVE: The objective of the study was to compare the CHD risk of subclinical hypothyroidism with and without thyroid peroxidase antibodies (TPOAbs). DATA SOURCES AND STUDY SELECTION: A MEDLINE and EMBASE search from 1950 to 2011 was conducted for prospective cohorts, reporting baseline thyroid function, antibodies, and CHD outcomes. DATA EXTRACTION: Individual data of 38 274 participants from six cohorts for CHD mortality followed up for 460 333 person-years and 33 394 participants from four cohorts for CHD events. DATA SYNTHESIS: Among 38 274 adults (median age 55 y, 63% women), 1691 (4.4%) had subclinical hypothyroidism, of whom 775 (45.8%) had positive TPOAbs. During follow-up, 1436 participants died of CHD and 3285 had CHD events. Compared with euthyroid individuals, age- and gender-adjusted risks of CHD mortality in subclinical hypothyroidism were similar among individuals with and without TPOAbs [hazard ratio (HR) 1.15, 95% confidence interval (CI) 0.87-1.53 vs HR 1.26, CI 1.01-1.58, P for interaction = .62], as were risks of CHD events (HR 1.16, CI 0.87-1.56 vs HR 1.26, CI 1.02-1.56, P for interaction = .65). Risks of CHD mortality and events increased with higher thyrotropin, but within each stratum, risks did not differ by TPOAb status. CONCLUSIONS: CHD risk associated with subclinical hypothyroidism did not differ by TPOAb status, suggesting that biomarkers of thyroid autoimmunity do not add independent prognostic information for CHD outcomes.

El llicenciat en ciències de l'activitat física i l'esport en el sistema sanitari

Els sistemes sanitaris dels països benestants s’enfronten cada dia a nous reptes generats per tot allò que prové de la salut individual i social. L’envelliment de la població i la manca d’exercici físic són dos factors que tenen una infl uència directa sobre la salut de les persones i que provoca que es plantegin noves logístiques i estructures dins els sistemes sanitaris per poder donar resposta a aquests factors. Són ben coneguts els benefi cis de l’exercici físic en la salut de les persones com a element preventiu i terapèutic. D’altra banda, l’exercici físic també està justifi cant i reivindicant la seva presència en el sistema sanitari, d’aquí la necessitat de crear la necessitat estructures i xarxes dins dels sistemes sanitaris que afavoreixin el treball de grups interdisciplinaris que integrin al llicenciat en ciències de l’activitat física i l’esport com a professional competent en la formació que ha rebut. L’aportació dels llicenciats en ciències de l’activitat física i l’esport en la prescripció d’exercici físic, conjuntament amb la resta de professionals com poden ser els facultatius, infermeria, fi sioterapeutes, entre d’altres, pot aportar benefi cis econòmics importants, sobretot pel que fa a l’estalvi en la despesa sanitària.

La humanización de las imágenens emitidas por la publicidad de los destinos monumentales: el caso de Girona

This article is based on the presentation of the results of a study on the humanisation of the image of cultural destinations, applied to the case of the city of Girona. According to the theories raised by different authors, we were interested in analyzing if the tourist images shown by the tourists publicity are influenced by romantic references typical of the dynamics of individual consumption. That is to say, if these images project a vision of an empty city, a museum.city, an individual panoramic or an individual consumption experience. The results of the analysis allow us to affirm that a mythical image of the city exists and it has a clearly romantic origin. Nevertheless, on the other hand, a specific glance exists where the tension between the indivudual freedom and the social conventionalism is demonstrated

Systems medicine and integrated care to combat chronic noncommunicable diseases

We propose an innovative, integrated, cost-effective health system to combat major non-communicable diseases (NCDs), including cardiovascular, chronic respiratory, metabolic, rheumatologic and neurologic disorders and cancers, which together are the predominant health problem of the 21st century. This proposed holistic strategy involves comprehensive patient-centered integrated care and multi-scale, multi-modal and multi-level systems approaches to tackle NCDs as a common group of diseases. Rather than studying each disease individually, it will take into account their intertwined gene-environment, socio-economic interactions and co-morbidities that lead to individual-specific complex phenotypes. It will implement a road map for predictive, preventive, personalized and participatory (P4) medicine based on a robust and extensive knowledge management infrastructure that contains individual patient information. It will be supported by strategic partnerships involving all stakeholders, including general practitioners associated with patient-centered care. This systems medicine strategy, which will take a holistic approach to disease, is designed to allow the results to be used globally, taking into account the needs and specificities of local economies and health systems.

Are R&D collaborative agreements persistent at the firm level? Empirical evidence for the Spanish case

We provide evidence on the dynamics in firms’ R&D cooperation behaviour. Our main objective is to analyse if R&D collaborative agreements are persistent at the firm level, and in such a case, to study what are the main drivers of this phenomenon. R&D cooperation activities at the firm level can be persistent due to true state dependence, this implying that cooperating in a given period enhances the probability of doing it in the subsequent period and it can also be a consequence of firms’ individual heterogeneity, so that certain firms have certain characteristics that make them more likely to carry out technological alliances.

Designing online interaction to address disciplinary competencies: A cross-country comparison of faculty perspectives

This study was conducted at colleges in three countries (United States, Venezuela, and Spain) and across three academic disciplines (engineering, education, and business), to examine how experienced faculty define competencies for their discipline, and design instructional interaction for online courses. A qualitative research design employing in-depth interviews was selected. Results show that disciplinary knowledge takes precedence when faculty members select competencies to be developed in online courses for their respective professions. In all three disciplines, the design of interaction to correspond with disciplinary competencies was often influenced by contextual factors that modify faculty intention. Therefore, instructional design will vary across countries in the same discipline to address the local context, such as the needs and expectations of the learners, faculty perspectives, beliefs and values, and the needs of the institution, the community, and country. The three disciplines from the three countries agreed on the importance of the following competencies: knowledge of the field, higher order cognitive processes such as critical thinking, analysis, problem solving, transfer of knowledge, oral and written communication skills, team work, decision making, leadership and management skills, indicating far more similarities in competencies than differences between the three different applied disciplines. We found a lack of correspondence between faculty¿s intent to develop collaborative learning skills and the actual development of them. Contextual factors such as faculty prior experience in design, student reluctance to engage in collaborative learning, and institutional assessment systems that focus on individual performance were some of these reasons.

EMBALAGEM INDIVIDUAL DE MANGAS CV. TOMMY ATKINS EM FILME PLÁSTICO: EFEITO SOBRE A VIDA DE PRATELEIRA

Estudou-se o efeito da embalagem de policloreto de vinila (PVC) sobre a vida de prateleira de mangas cv. Tommy Atkins armazenadas sob refrigeração. Mangas no estádio de maturidade fisiológica, com casca verde ou levemente avermelhada, foram embaladas individualmente, com filme de 10mm de espessura, e armazenadas por 28 dias a 12ºC (80-90% UR). Frutos sem embalagem serviram de controle. Durante o período de armazenagem, foram feitas avaliações sensoriais utilizando o método de escala hedônica não estruturada para aceitação da aparência e do sabor, utilizando-se de 30 provadores não treinados por sessão. Determinou-se também a perda de massa, a acidez titulável e os teores de sólidos solúveis e vitamina C ao longo da armazenagem. As mangas embaladas apresentaram uma vida de prateleira de 21 dias contra 6 dias das não embaladas, e uma taxa de perda de massa 3,5 vezes menor que as não embaladas. Em relação à taxa de degradação de vitamina C, não houve diferença entre os tratamentos. A combinação da embalagem com a armazenagem a 12ºC aumentou a vida de prateleira do produto pela redução da atividade metabólica e do desenvolvimento de podridão.

Trials using a crossover design and ambulatory blood pressure recordings to determine the efficacy of antihypertensive agents in individual patients.

The antihypertensive effects of the beta-blocking agent betaxolol and the calcium entry blocker verapamil were compared in a crossover single-blind trial. Seventeen patients with uncomplicated essential hypertension took either betaxolol or a slow-release formulation of verapamil for two consecutive 6-week periods. The sequence of treatment phases was randomly allocated and a 2-week washout period preceded each treatment. The antihypertensive effect of the test drugs was assessed both at the physician's office and during everyday activities using a portable blood pressure recorder. The crossover design of the trial made it possible to evaluate the antihypertensive efficacy of betaxolol and verapamil both in the group as a whole and in the individual patient. The individual patient response to one of these agents was not a reliable indicator of the same patient's response to the alternative agent. Betaxolol brought both office and ambulatory recorded blood pressures under control in a larger fraction of patients than verapamil, although the magnitude of the blood pressure fall in the responders was equal for each drug. These observations stress the need for an individualized approach to the evaluation of antihypertensive therapy. The present results also demonstrate that optimal antihypertensive therapy is still a matter of trial and error. The precise methodology that ought to characterize crossover trials may make it possible to improve the therapeutic approach to hypertensive patients.
