Kenya after the 2007 "post-election violence" : constitutional reform and the National Accord and Reconciliation Act

Immediately after the announcement of the re-election of President Kibaki on the evening of 30 December 2007, Kenya was thrust into the worst civil unrest experienced by the country since independence – a development that became known as the "Post-Election Violence" (PEV). However, after a subsequent process of reconciliation, the PEV came to an end within a relatively short period. The present-day politics of Kenya are being conducted within the framework of a provisional Constitution that took shape through peaceful mediation. How did Kenya manage to put a lid on a period of turmoil that placed the country in unprecedented danger? This paper traces the sequence of events that led to mediation, explains the emergency measures that were needed to maintain law and order, and indicates the remaining problems that still need to be solved.

A New End-User Composition Model to Empower Knowledge Workers to Develop Rich Internet Applications

Enabling real end-user programming development is the next logical stage in the evolution of Internetwide service-based applications. Even so, the vision of end users programming their own web-based solutions has not yet materialized. This will continue to be so unless both industry and the research community rise to the ambitious challenge of devising an end-to-end compositional model for developing a new age of end-user web application development tools. This paper describes a new composition model designed to empower programming-illiterate end users to create and share their own off-the-shelf rich Internet applications in a fully visual fashion. This paper presents the main insights and outcomes of our research and development efforts as part of a number of successful European Union research projects. A framework implementing this model was developed as part of the European Seventh Framework Programme FAST Project and the Spanish EzWeb Project and allowed us to validate the rationale behind our approach.

Aplicación de documentos de identificación electrónica a un esquema de voto telemático a escala paneuropea, seguro, auditable y verificable.

En este trabajo de tesis se propone un esquema de votación telemática, de carácter paneuropeo y transnacional, que es capaz de satisfacer las más altas exigencias en materia de seguridad. Este enfoque transnacional supone una importante novedad que obliga a identificar a los ciudadanos más allá de las fronteras de su país, exigencia que se traduce en la necesidad de que todos los ciudadanos europeos dispongan de una identidad digital y en que ésta sea reconocida más allá de las fronteras de su país de origen. Bajo estas premisas, la propuesta recogida en esta tesis se aborda desde dos vertientes complementarias: por una parte, el diseño de un esquema de votación capaz de conquistar la confianza de gobiernos y ciudadanos europeos y, por otra, la búsqueda de una respuesta al problema de interoperabilidad de Sistemas de Gestión de Identidad (IDMs), en consonancia con los trabajos que actualmente realiza la UE para la integración de los servicios proporcionados por las Administraciones Públicas de los distintos países europeos. El punto de partida de este trabajo ha sido la identificación de los requisitos que determinan el adecuado funcionamiento de un sistema de votación telemática para, a partir de ellos,proponer un conjunto de elementos y criterios que permitan, por una parte, establecer comparaciones entre distintos sistemas telemáticos de votación y, por otra, evaluar la idoneidad del sistema propuesto. A continuación se han tomado las más recientes y significativas experiencias de votación telemática llevadas a cabo por diferentes países en la automatización de sus procesos electorales, analizándolas en profundidad para demostrar que, incluso en los sistemas más recientes, todavía subsisten importantes deficiencias relativas a la seguridad. Asimismo, se ha constatado que un sector importante de la población se muestra receloso y, a menudo, cuestiona la validez de los resultados publicados. Por tanto, un sistema que aspire a ganarse la confianza de ciudadanos y gobernantes no sólo debe operar correctamente, trasladando los procesos tradicionales de votación al contexto telemático, sino que debe proporcionar mecanismos adicionales que permitan superar los temores que inspira el nuevo sistema de votación. Conforme a este principio, el enfoque de esta tesis, se orienta, en primer lugar, hacia la creación de pruebas irrefutables, entendibles y auditables a lo largo de todo el proceso de votación, que permitan demostrar con certeza y ante todos los actores implicados en el proceso (gobierno, partidos políticos, votantes, Mesa Electoral, interventores, Junta Electoral,jueces, etc.) que los resultados publicados son fidedignos y que no se han violado los principios de anonimato y de “una persona, un voto”. Bajo este planteamiento, la solución recogida en esta tesis no sólo prevé mecanismos para minimizar el riesgo de compra de votos, sino que además incorpora mecanismos de seguridad robustos que permitirán no sólo detectar posibles intentos de manipulación del sistema, sino también identificar cuál ha sido el agente responsable. De forma adicional, esta tesis va más allá y traslada el escenario de votación a un ámbito paneuropeo donde aparecen nuevos problemas. En efecto, en la actualidad uno de los principales retos a los que se enfrentan las votaciones de carácter transnacional es sin duda la falta de procedimientos rigurosos y dinámicos para la actualización sincronizada de los censos de votantes de los distintos países que evite la presencia de errores que redunden en la incapacidad de controlar que una persona emita más de un voto, o que se vea impedido del todo a ejercer su derecho. Este reconocimiento de la identidad transnacional requiere la interoperabilidad entre los IDMs de los distintos países europeos. Para dar solución a este problema, esta tesis se apoya en las propuestas emergentes en el seno de la UE, que previsiblemente se consolidarán en los próximos años, tanto en materia de identidad digital (con la puesta en marcha de la Tarjeta de Ciudadano Europeo) como con el despliegue de una infraestructura de gestión de identidad que haga posible la interoperabilidad de los IDMs de los distintos estados miembros. A partir de ellas, en esta tesis se propone una infraestructura telemática que facilita la interoperabilidad de los sistemas de gestión de los censos de los distintos estados europeos en los que se lleve a cabo conjuntamente la votación. El resultado es un sistema versátil, seguro, totalmente robusto, fiable y auditable que puede ser aplicado en elecciones paneuropeas y que contempla la actualización dinámica del censo como una parte crítica del proceso de votación. ABSTRACT: This Ph. D. dissertation proposes a pan‐European and transnational system of telematic voting that is capable of meeting the strictest security standards. This transnational approach is a significant innovation that entails identifying citizens beyond the borders of their own country,thus requiring that all European citizens must have a digital identity that is recognized beyond the borders of their country of origin. Based on these premises, the proposal in this thesis is analyzed in two mutually‐reinforcing ways: first, a voting system is designed that is capable of winning the confidence of European governments and citizens and, second, a solution is conceived for the problem of interoperability of Identity Management Systems (IDMs) that is consistent with work being carried out by the EU to integrate the services provided by the public administrations of different European countries. The starting point of this paper is to identify the requirements for the adequate functioning of a telematic voting system and then to propose a set of elements and criteria that will allow for making comparisons between different such telematic voting systems for the purpose of evaluating the suitability of the proposed system. Then, this thesis provides an in‐depth analysis of most recent significant experiences in telematic voting carried out by different countries with the aim of automating electoral processes, and shows that even the most recent systems have significant shortcomings in the realm of security. Further, a significant portion of the population has shown itself to be wary,and they often question the validity of the published results. Therefore, a system that aspires to win the trust of citizens and leaders must not only operate correctly by transferring traditional voting processes into a telematic environment, but must also provide additional mechanisms that can overcome the fears aroused by the new voting system. Hence, this thesis focuses, first, on creating irrefutable, comprehensible and auditable proof throughout the voting process that can demonstrate to all actors in the process – the government, political parties, voters, polling station workers, electoral officials, judges, etc. ‐that the published results are accurate and that the principles of anonymity and one person,one vote, have not been violated. Accordingly, the solution in this thesis includes mechanisms to minimize the risk of vote buying, in addition to robust security mechanisms that can not only detect possible attempts to manipulate the system, but also identify the responsible party. Additionally, this thesis goes one step further and moves the voting scenario to a pan‐European scale, in which new problems appear. Indeed, one of the major challenges at present for transnational voting processes is the lack of rigorous and dynamic procedures for synchronized updating of different countries’ voter rolls, free from errors that may make the system unable to keep an individual from either casting more than one vote, or from losing the effective exercise of the right to vote. This recognition of transnational identity requires interoperability between the IDMs of different European countries. To solve the problem, this thesis relies on proposals emerging within the EU that are expected to take shape in the coming years, both in digital identity – with the launch of the European Citizen Card – and in the deployment of an identity management infrastructure that will enable interoperability of the IDMs of different member states. Based on these, the thesis proposes a telematic infrastructure that will achieve interoperability of the census management systems of European states in which voting processes are jointly carried out. The result is a versatile, secure, totally robust, reliable and auditable system that can be applied in pan‐European election, and that includes dynamic updating of the voter rolls as a critical part of the voting process.

Leader Rural Development Program in Spain: Profile and Functions of Workers in Local Action Groups.

Occupations in the labor market are linked with to a minimum basic training and other capacities. Hired workers should be able to accomplish required functions related to their specific job. Regarding the rural development labor market, local action groups? workers have defined performance areas?projects, strategy, organization and training & market?but specific functions within each of these areas are not as clearly defined. Neither both, basic training and capacities needed to perform each job profile within the local action group are defined. This communication analyses training and other capacities linked to each of the job profiles within the local action group. Functions within each of the performance areas previously defined are also analyzed regarding the job profiles.

Eventual election of multiple leaders for solving consensus in anonymous systems

In classical distributed systems, each process has a unique identity. Today, new distributed systems have emerged where a unique identity is not always possible to be assigned to each process. For example, in many sensor networks a unique identity is not possible to be included in each device due to its small storage capacity, reduced computational power, or the huge number of devices to be identified. In these cases, we have to work with anonymous distributed systems where processes cannot be identified. Consensus cannot be solved in classical and anonymous asynchronous distributed systems where processes can crash. To bypass this impossibility result, failure detectors are added to these systems. It is known that ? is the weakest failure detector class for solving consensus in classical asynchronous systems when amajority of processes never crashes. Although A? was introduced as an anonymous version of ?, to find the weakest failure detector in anonymous systems to solve consensus when amajority of processes never crashes is nowadays an open question. Furthermore, A? has the important drawback that it is not implementable. Very recently, A? has been introduced as a counterpart of ? for anonymous systems. In this paper, we show that the A? failure detector class is strictly weaker than A? (i.e., A? provides less information about process crashes than A?). We also present in this paper the first implementation of A? (hence, we also show that A? is implementable), and, finally, we include the first implementation of consensus in anonymous asynchronous systems augmented with A? and where a majority of processes does not crash.

Dispersal of first “workers” in social wasps: Causes and implications of an alternative reproductive strategy

Many “workers” in north temperate colonies of the eusocial paper wasp Polistes fuscatus disappear within a few days of eclosion. We provide evidence that these females are pursuing an alternative reproductive strategy, i.e., dispersing to overwinter and become nest foundresses the following spring, instead of helping to rear brood on their natal nests. A female is most likely to stay and help at the natal nest (i.e., least likely to disperse) when it is among the first workers to emerge and when it emerges on a nest with more pupae (even though worker-brood relatedness tends to be lower in such colonies). The latter cause may result from the fact that pupae-laden nests are especially likely to survive, and thus any direct or indirect reproductive payoffs for staying and working are less likely to be lost. Disappearing females are significantly smaller than predicted if dispersal tendency was independent of body size (emergence order-controlled), suggesting that the females likely to be most effective at challenging for reproductive rights within the natal colony (i.e., the largest females) are also most likely to stay. Thus, early dispersal is conditional on a female’s emergence order, the maturity of its natal nest, and its body size. Finally, we present evidence that foundresses may actively limit the sizes of first-emerging females, perhaps to decrease the probability that the latter can effectively challenge foundresses for reproductive rights. The degree to which foundresses limit the size of first-emerging females accords well with the predictions of the theory of staying incentives.

The impact of interindividual variation in NAT2 activity on benzidine urinary metabolites and urothelial DNA adducts in exposed workers.

Several epidemiologic studies indicate that NAT2-related slow N-acetylation increases bladder cancer risk among workers exposed to aromatic amines, presumably because N-acetylation is important for the detoxification of these compounds. Previously, we showed that NAT2 polymorphisms did not influence bladder cancer risk among Chinese workers exposed exclusively to benzidine (BZ), suggesting that NAT2 N-acetylation is not a critical detoxifying pathway for this aromatic amine. To evaluate the biologic plausibility of this finding, we carried out a cross-sectional study of 33 workers exposed to BZ and 15 unexposed controls in Ahmedabad, India, to evaluate the presence of BZ-related DNA adducts in exfoliated urothelial cells, the excretion pattern of BZ metabolites, and the impact of NAT2 activity on these outcomes. Four DNA adducts were significantly elevated in exposed workers compared to controls; of these, the predominant adduct cochromatographed with a synthetic N-(3'- phosphodeoxyguanosin-8-yl)-N'-acetylbenzidine standard and was the only adduct that was significantly associated with total BZ urinary metabolites (r = 0.68, P < 0.0001). To our knowledge this is the first report to show that BZ forms DNA adducts in exfoliated urothelial cells of exposed humans and that the predominant adduct formed is N-acetylated, supporting the concept that monofunctional acetylation is an activation, rather than a detoxification, step for BZ. However, because almost all BZ-related metabolites measured in the urine of exposed workers were acetylated among slow, as well as rapid, acetylators (mean +/- SD 95 +/- 1.9% vs. 97 +/- 1.6%, respectively) and NAT2 activity did not affect the levels of any DNA adduct measured, it is unlikely that interindividual variation in NAT2 function is relevant for BZ-associated bladder carcinogenesis.

Reproductive cooperation between queens and their mated workers: the complex life history of an ant with a valuable nest.

The life history of Harpegnathos saltator is exceptional among ants because both queens and workers reproduce sexually. Recently mated queens start new colonies alone, but later some of the offspring workers also become inseminated and take over the egg-laying role. This alternation seems associated with the existence of very complex underground nests, which are designed to survive floods. Longevity of ponerine queens is low (a consequence of limited caste dimorphism in this "primitive" subfamily), and upon the death of an H. saltator foundress, the nest represents a substantial investment. The queen's progeny should thus be strongly selected to retain the valuable nests. Unlike the flying queens, the workers copulate with males from their own colonies, and, thus, their offspring are expected to be highly related to the foundress. Colony fission appears not to occur because a daughter fragment would lack an adequate nest for protection. Thus, the annual production of queens in colonies with reproductive workers remains essential for the establishment of new colonies. This contrasts with various other ponerine species in which the queens no longer exist.
