Election Studies in India

The election system is the pillar of Indian democracy. The system consists of various levels of elections to the Lok Sabha (the House of Representatives of the Union), State Legislative Assemblies, and Panchayati Raj Institutions (local self-governing bodies under State Governments). This article includes a review of studies related to the elections of Lok Sabha and State Legislative Assemblies conducted up to the present time. Studies are divided into those based on aggregate data and those based on survey data of the individual electorate. This division has the advantage of providing data that may be used in different analytical areas. Voter turnout and votes polled by party are the two main variables to be explained. This review article thus shows what has been explained in voting behaviour in India up to the present time.

Ethnicity and Elections under Authoritarianism: The Case of Kazakhstan

Despite the ethnicisation of power since independence in 1991, Kazakhstan has managed to maintain political stability without experiencing large-scale mobilisation to oppose Kazakh domination. This paper examines government strategy to avoid ethnic voting in an attempt to explain why ethnic divisions were rarely reflected in the struggle for power in the republic. While the arbitrary use of legal provisions considerably limited participation in elections by ethnic leaders, powerful pro-president parties that exhibited a cross-ethnic character were created to curtail ethnically based movements. The control strategy in elections aimed not simply at ethnicising the parliament in favour of Kazakhs, but at having loyal Russians and other minorities represented in the legislature through nomination by the president and catch-all pro-regime parties, or through the presidential consultative body—Assembly of the People of Kazakhstan. This well-controlled representation of minorities served not only to placate non-Kazakhs but also to provide legitimacy for the Kazakh-dominated leadership by projecting the image of cross-ethnic support for the president and some degree of power-sharing.

Political limits on the world oil trade : firm-level evidence from US firms

International politics affect trade patterns, especially for firms in extractive industries. We construct the firm-level dataset for the U.S. oil-importing companies over 1986-2010 to test whether the state of international relations with the trading partners of the U.S. affect importing behavior of the U.S. firms. To measure "political distance" between the U.S. and her trading partners we use voting records for the UN General Assembly. We find that the U.S. firms, in fact, import significantly less oil from the political opponents of the U.S. Our conjecture is that the decrease in oil imports is mainly driven by large, vertically-integrated U.S. firms that engage in foreign direct investment (FDI) overseas.

Why do oil importers diversify their import sources politically? : evidence from U.S. firm-level data

International politics affects oil trade. But why? We construct a firm-level dataset for all U.S. oil-importing companies over 1986-2008 to examine what kinds of firms are more responsive to change in "political distance" between the U.S. and her trading partners, measured by divergence in their UN General Assembly voting patterns. Consistent with previous macro evidence, we first show that individual firms diversify their oil imports politically, even after controlling for unobserved firm heterogeneity. We conjecture that the political pattern of oil imports from these individual firms is driven by hold-up risks, because oil trade is often associated with backward vertical FDI. To test this hold-up risk hypothesis, we investigate heterogeneity in responses by matching transaction-level import data with firm-level worldwide reserves. Our results show that long-run oil import decisions are indeed more elastic for firms with oil reserves overseas than those without, although the reverse is true in the short run. We interpret this empirical regularity as that while firms trade in the spot market can adjust their imports immediately, vertically-integrated firms with investment overseas tend to commit to term contracts in the short run even though they are more responsive to changes in international politics in the long run.

The effects of international politics on oil-exporting developing countries

International politics affects oil trade. But does it affect the oil-exporting developing countries more? We construct a firm-level dataset for all U.S. oil-importing companies over 1986-2008 to examine how these firms respond to changes in "political distance" between the U.S. and her trading partners, measured by divergence in their UN General Assembly voting patterns. Consistent with previous macro evidence, we first show that individual firms diversify their oil imports politically, even after controlling for unobserved firm heterogeneity. We conjecture that the political pattern of oil imports from these individual firms is driven by hold-up risks, because oil trade is often associated with backward vertical FDI. To the extent that developing countries have higher hold-up risks because of their weaker institutions, the political effect on oil trade should be more significant in the developing world. We find that oil import decisions are indeed more elastic when firms import from developing countries, although the reverse is true in the short run. Our results suggest that international politics can affect oil revenue and hence long-term development in the developing world.

Political influence in commercial and financial oil trading : the evidence from US firms

International politics affects oil trade. But do financial and commercial traders who participate in spot oil trading also respond to changes in international politics? We construct a firm-level dataset for all U.S. oil-importing companies over 1986-2008 to examine how these firms respond to increases in "political distance" between the U.S. and her trading partners, measured by divergence in their UN General Assembly voting patterns. Consistent with previous macro evidence, we first show that individual firms diversify their oil imports politically, even after controlling for unobserved firm heterogeneity. However, the political pattern of oil imports is not entirely driven by the concerns of hold-up risks, which exist when oil transactions via term contracts are associated with backward vertical FDI that is subject to expropriation. In particular, our results indicate that even financial and commercial traders significantly reduce their oil imports from U.S. political enemies. Interestingly, while these traders diversify their oil imports politically immediately after changes in international politics, other oil companies reduce their oil imports with a significant time lag. Our findings suggest that in designing regulations to avoid harmful repercussions on commodity and financial assets, policymakers need to understand the nature of political risk.

Accession clause of TPP : Is it really open?

One of the most important policy questions relating to the future impact of the Trans-Pacific Partnership on the global and regional economy is whether other countries in the region, particularly China, will join the partnership. While several commentators have made some observations regarding the future prospects of TPP expansion, little scholarly analysis has been conducted. To go beyond the speculation of a certain country's accession to TPP, we first attempt to generalize the issue before moving on to a specific question. We conduct a comparative analysis of a large number of regional trade agreements for a better understanding of the parameters of RTAs that are critical for membership expansion. This general framework enables us to conduct a systematic examination of specific membership expansion cases, such as China's membership in TPP. The paper also proposes a necessary "accession practice" that truly facilitates new members' participation.

Fuzzy min-max neural networks for categorical data: application to missing data imputation

The fuzzy min–max neural network classifier is a supervised learning method. This classifier takes the hybrid neural networks and fuzzy systems approach. All input variables in the network are required to correspond to continuously valued variables, and this can be a significant constraint in many real-world situations where there are not only quantitative but also categorical data. The usual way of dealing with this type of variables is to replace the categorical by numerical values and treat them as if they were continuously valued. But this method, implicitly defines a possibly unsuitable metric for the categories. A number of different procedures have been proposed to tackle the problem. In this article, we present a new method. The procedure extends the fuzzy min–max neural network input to categorical variables by introducing new fuzzy sets, a new operation, and a new architecture. This provides for greater flexibility and wider application. The proposed method is then applied to missing data imputation in voting intention polls. The micro data—the set of the respondents’ individual answers to the questions—of this type of poll are especially suited for evaluating the method since they include a large number of numerical and categorical attributes.

The application of biomechanics to penalty corner drag-flick training: a case of Study

The penalty corner is one of the most important game situations in field hockey with one third of all goals resulting from this tactical situation. The aim of this study was to develop and apply a training method, based on previous studies, to improve the drag- flick skill on a young top-class field hockey player. A young top-class player exercised three times per week using specific drills over a four week period. A VICON optoelectronic system (Oxford Metrics, Oxford, UK) was employed to capture twenty drag-flicks, with six cameras sampling at 250 Hz, prior and after the training period. In order to analyze pre- and post-test differences a dependent t-test was carried out. Angular velocities and the kinematic sequence were similar to previous studies. The player improved (albeit not significantly) the angular velocity of the stick. The player increased front foot to the ball at T1 (p < 0.01) and the drag-flick distances. The range of motion from the front leg decreased from T1 to T6 after the training period (p < 0.01). The specific training sessions conducted with the player improved some features of this particular skill. This article shows how technical knowledge can help with the design of training programs and whether some drills are more effective than others.

Simulación de maniobras de buques con sistemas de propulsión no convencional en aguas poco profundas

Los requisitos cada vez más exigentes en cuanto a misiones, limitaciones operacionales y ambientales así como nuevas tecnologías, imponen permanentemente retos a los arquitectos navales para generar alternativas de buques y valorar su bondad en las primeras etapas del proyecto. Este es el caso de los Buques Patrulleros de Apoyo Fluvial Pesados PAF-P, que por requerimiento de la Armada Nacional de Colombia ha diseñado y construido COTECMAR. Los PAF-P, son buques fluviales cuya relación Manga-Calado excede la mayoría de los buques existentes (B/T=9,5), debido principalmente a las restricciones en el calado a consecuencia de la escasa profundidad de los ríos. Estos buques están equipados con sistemas de propulsión acimutales tipo “Pum-Jet”. Las particularidades del buque y del ambiente operacional, caracterizado por ríos tropicales con una variabilidad de profundidad dependiente del régimen de lluvias y sequía, así como la falta de canalización y la corriente, hacen que la maniobrabilidad y controlabilidad sean fundamentales para el cumplimiento de su misión; adicionalmente, no existen modelos matemáticos validados que permitan predecir en las primeras etapas del diseño la maniobrabilidad de este tipo de buques con los efectos asociados por profundidad. La presente tesis doctoral aborda el desarrollo de un modelo matemático para simulación de maniobrabilidad en aguas poco profundas de buques con relación manga-calado alta y con propulsores acimutales tipo “Pump-Jet”, cuyo chorro además de entregar el empuje necesario para el avance del buque, genera la fuerza de gobierno en función del ángulo de orientación del mismo, eliminando la necesidad de timones. El modelo matemático ha sido validado mediante los resultados obtenidos en las pruebas de maniobrabilidad a escala real del PAF-P, a través de la comparación de trayectorias, series temporales de las variables de estado más significativas y parámetros del círculo evolutivo como son diámetro de giro, diámetro táctico, avance y transferencia. El plan de pruebas se basó en técnicas de Diseño de Experimentos “DOE” para racionalizar el número de corridas en diferentes condiciones de profundidad, velocidad y orientación del chorro (ángulo de timón). En el marco de la presente investigación y para minimizar los errores por efectos ambientales y por inexactitud en los instrumentos de medición, se desarrolló un sistema de adquisición y procesamiento de datos de acuerdo con los lineamientos de ITTC. La literatura existente describe los efectos negativos de la profundidad en los parámetros de maniobrabilidad de buques convencionales (Efecto tipo S), principalmente las trayectorias descritas en los círculos evolutivos aumentan en la medida que disminuye la profundidad; no obstante, en buques de alta relación manga-calado, B/T=7,51 (Yoshimura, y otros, 1.988) y B/T=6,38 (Yasukawa, y otros, 1.995) ha sido reportado el efecto contrario (Efecto tipo NS Non Standart). Este último efecto sin embargo, ha sido observado mediante experimentación con modelos a escala pero no ha sido validado en pruebas de buques a escala real. El efecto tipo NS en buques dotados con hélice y timones, se atribuye al mayor incremento de la fuerza del timón comparativamente con las fuerzas del casco en la medida que disminuye la profundidad; en el caso de estudio, el fenómeno está asociado a la mejor eficiencia de la bomba de agua “Pump-Jet”, debido a la resistencia añadida en el casco por efecto de la disminución de la profundidad. Los resultados de las pruebas con buque a escala real validan el excelente desempeño de esta clase de buques, cumpliendo en exceso los criterios de maniobrabilidad existentes y muestran que el diámetro de giro y otras características de maniobrabilidad mejoran con la disminución de la profundidad en buques con alta relación manga-calado. ABSTRACT The increasingly demanding requirements in terms of missions, operational and environmental constraints as well as new technologies, constantly impose challenges to naval architects to generate alternatives and asses their performance in the early stages of design. That is the case of Riverine Support Patrol Vessel (RSPV), designed and built by COTECMAR for the Colombian Navy. RSPV are riverine ships with a Beam-Draft ratio exceeding most of existing ships (B/T=9,5), mainly due to the restrictions in draft as a result of shallow water environment. The ships are equipped with azimuthal propulsion system of the “Pump-Jet” type. The peculiarities of the ship and the operational environment, characterized by tropical rivers of variable depth depending on the rain and dry seasons, as well as the lack channels and the effect of water current, make manoeuvrability and controllability fundamental to fulfill its mission; on the other hand, there are not validated mathematical models available to predict the manoeuvrability of such ships with the associated water depth effects in the early stages of design. This dissertation addresses the development of a mathematical model for shallow waters’ manoeuvrability simulation of ships with high Beam-Draft ratio and azimuthal propulsion systems type “Pump-Jet”, whose stream generates the thrust required by the ship to advance and also the steering force depending on the orientation angle, eliminating the need of rudders. The mathematical model has been validated with the results of RSPV’s full scale manoeuvring tests, through a comparison of paths, time series of state variables and other parameters taken from turning tests, such as turning diameter, tactical diameter, advance and transfer. The test plan was developed applying techniques of Design of Experiments “DOE”, in order to rationalize the number of runs in different conditions of water depth, ship speed and jet stream orientation (rudder angle). A data acquisition and processing system was developed, following the guidelines of ITTC, as part of this research effort, in order to minimize errors by environmental effects and inaccuracy in measurement instruments, The negative effects of depth on manoeuvrability parameters for conventional ships (Effect Type S: the path described by the ship during turning test increase with decrease of water depth), has been documented in the open literature; however for wide-beam ships, B/T=7,51 (Yoshimura, y otros, 1.988) and B/T=6,38 (Yasukawa, y otros, 1.995) has been reported the opposite effect (Type NS). The latter effect has been observed thru model testing but until now had not been validated with full-scale results. In ships with propellers and rudders, type NS effect is due to the fact that increment of rudder force becomes larger than hull force with decrease of water depth; in the study case, the phenomenon is associated with better efficiency of the Pump-Jet once the vessel speed becomes lower, due to hull added resistance by the effect of the decrease of water depth. The results of full scale tests validates the excellent performance of this class of ships, fulfilling the manoeuvrability criteria in excess and showing that turning diameter and other parameters in high beam-draft ratio vessels do improve with the decrease of depth.

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.

Container Terminal Simulation. A case study: port of Valencia.

This paper is concerned with the study of non-Markovian queuing systems in container terminals. The methodology presented has been applied to analyze the ship traffic in the port of Valencia located in the Western Mediterranean. Two container terminals have been studied: the public container terminal of NOATUM and the dedicated container terminal of MSC. This paper contains the results of a simulation model based on queuing theory. The methodology presented is found to be effective in replicating realistic ship traffic operations in port as well as in conducting capacity evaluations. Thus the methodology can be used for capacity planning (long term), tactical planning (medium term) and even for the container terminal design (port enlargement purposes).

A collaborative filtering similarity measure based on singularities.

Recommender systems play an important role in reducing the negative impact of informa- tion overload on those websites where users have the possibility of voting for their prefer- ences on items. The most normal technique for dealing with the recommendation mechanism is to use collaborative filtering, in which it is essential to discover the most similar users to whom you desire to make recommendations. The hypothesis of this paper is that the results obtained by applying traditional similarities measures can be improved by taking contextual information, drawn from the entire body of users, and using it to cal- culate the singularity which exists, for each item, in the votes cast by each pair of users that you wish to compare. As such, the greater the measure of singularity result between the votes cast by two given users, the greater the impact this will have on the similarity. The results, tested on the Movielens, Netflix and FilmAffinity databases, corroborate the excellent behaviour of the singularity measure proposed.

Relevance of motion-related assessment metrics in laparoscopic surgery

INTRODUCTION: Motion metrics have become an important source of information when addressing the assessment of surgical expertise. However, their direct relationship with the different surgical skills has not been fully explored. The purpose of this study is to investigate the relevance of motion-related metrics in the evaluation processes of basic psychomotor laparoscopic skills, as well as their correlation with the different abilities sought to measure. METHODS: A framework for task definition and metric analysis is proposed. An explorative survey was first conducted with a board of experts to identify metrics to assess basic psychomotor skills. Based on the output of that survey, three novel tasks for surgical assessment were designed. Face and construct validation study was performed, with focus on motion-related metrics. Tasks were performed by 42 participants (16 novices, 22 residents and 4 experts). Movements of the laparoscopic instruments were registered with the TrEndo tracking system and analyzed. RESULTS: Time, path length and depth showed construct validity for all three tasks. Motion smoothness and idle time also showed validity for tasks involving bi-manual coordination and tasks requiring a more tactical approach respectively. Additionally, motion smoothness and average speed showed a high internal consistency, proving them to be the most task-independent of all the metrics analyzed. CONCLUSION: Motion metrics are complementary and valid for assessing basic psychomotor skills, and their relevance depends on the skill being evaluated. A larger clinical implementation, combined with quality performance information, will give more insight on the relevance of the results shown in this study.
