El papel de las organizaciones Internacionales en la imagen de los Estados en el escenario internacional: La crisis Financiera de Argentina y la actuación del Fondo Monetario Internacional 2000- 2010

El presente trabajo de investigación tiene como objetivo identificar el papel que tuvo el Fondo Monetario Internacional [FMI] en el cambio de la imagen del Estado argentino después de la crisis financiera que estalló en el 2001. Como consecuencia de la declaración de default por parte del gobierno argentino se da un cambio en la imagen financiera del país, influenciada por el FMI, que convierte a Argentina en un paria internacional en temas financieros y comerciales alejándolo de los mercados internacionales. Este estudio de caso tendrá un acercamiento cualitativo dado que se analizarán las características, actuaciones y las bases crean el lazo entre las variables de la crisis financiera y el rol del FMI en Argentina y así poder entender su relación.

Impacto del Internet en el ingreso laboral: análisis del lugar y manejo del Internet

Este estudio analiza el efecto del uso de Internet sobre el ingreso laboral, eliminado el problema de endogeneidad que existe por motivos de selección. También se analizan los efectos seg un el lugar de acceso y las actividades realizadas en Internet. Para esto se utiliza Propensity Score Matching, tomando información para Colombia entre el año 2009 a 2011. Los resultados muestran que existe un efecto positivo, significativo y heterogéneo entre trabajadores asalariados y cuenta propia, siendo los últimos los más beneficiados. Con respecto al lugar de uso se encuentra un impacto positivo del uso del Internet en el trabajo y/o en el hogar, con una mayor magnitud en el primer sitio de acceso. Para el tema del manejo del Internet, no se encuentra efecto cuando se utiliza en actividades de entretenimiento, pero si cuando se usa en tareas educativas diariamente. Esto siguiere que usar este servicio aumenta la productividad y el capital humano, lo que se transforma en un incremento en los ingresos. Por tanto, se encuentra que el lugar de uso es una señal informativa para el mercado laboral, mientras que el impacto del manejo de esta herramienta depende de la frecuencia con que se realicen las actividades.

Learning how (not) to fire a gun: combatant training and civilian victimization

What is the relationship between the type of training combatants receive upon recruitment into an armed group and their propensity to abuse civilians in civil war? Does military training or political training prevent or exacerbate the victimization of civilians by armed non-state actors? While the literature on civilian victimization has expanded rapidly, few studies have examined the correlation between abuse of civilians and the modes of training that illegal armed actors receive. Using a simple formal model, we develop hypotheses regarding this connection and argue that while military training should not decrease the probability that a combatant engages in civilian abuse, political training should. We test these hypotheses using a new survey consisting of a representative sample of approximately 1,500 demobilized combatants from the Colombian conflict, which we match with department-level data on civilian casualties. The empirical analysis confirms our hypotheses about the connection between training and civilian abuse and the results are robust to adding a full set of controls both at the department and at the individual level

Estimaciones de los determinantes de los ingresos laborales en Colombia con consideraciones diferenciales para asalariados y cuenta propia

La literatura sobre determinantes de los ingresos laborales ha evolucionado en sus fundamentos teóricos, metodológicos y estimaciones empíricas. Colombia no ha sido ajena a este proceso, pero su evolución, notoria en fertilidad, ha venido relajándose en rigor conceptual: se tiende a considerar a los cuenta propia y asalariados como categorías relativamente semejantes. Para mostrar el efecto de dicha relajación realizamos estimaciones conjuntas de determinantes del ingreso laboral para ocupados asalariados y cuenta propia, y luego las contrastamos con estimaciones más detalladas y desagregadas ilustrando los sesgos efectivos que se generan si no se tienen en cuenta las características laborales de los ocupados cuenta propia y asalariado.

The crime kuznets curve

We document the existence of a Crime Kuznets Curve in US states since the 1970s. As income levels have risen, crime has followed an inverted U-shaped pattern, first increasing and then dropping. The Crime Kuznets Curve is not explained by income inequality. In fact, we show that during the sample period inequality has risen monotonically with income, ruling out the traditional Kuznets Curve. Our finding is robust to adding a large set of controls that are used in the literature to explain the incidence of crime, as well as to controlling for state and year fixed effects. The Curve is also revealed in nonparametric specifications. The Crime Kuznets Curve exists for property crime and for some categories of violent crime.

Interacciones de género estudiante-profesor, deserción y rendimiento académico en Colombia

En este trabajo se estima el efecto del género del profesor sobre la deserción y el rendimiento educativo de los estudiantes en Colombia durante el periodo 2009-2012. La estrategia empírica se fundamenta en un modelo de regresión lineal que establece la relación entre la proporción de profesoras interactuada con el género del estudiante. Los resultados sugieren que existe un sesgo de selección debido a que las profesoras aumentan la probabilidad de que las niñas finalicen la educación media, lo que implica que la composición de habilidades entre hombres y mujeres no es la misma. Luego de corregir este sesgo de selección, se encuentra un resultado significativo en el género del profesor. Un aumento de una desviación estándar en la proporción de profesoras incrementa en 0.01 desviaciones estándar el puntaje de los niños en la prueba de matemáticas y el puntaje de las niñas en la prueba de lenguaje. Este trabajo utiliza información proveniente de la prueba Saber 11, la Resolución 166 y el concurso docente.

Hisendes locals i turisme: tres assaigs

Aquesta tesi utilitza l'anàlisi econòmica per a estudiar les hisendes locals, especialment els aspectes relacionats amb la provisió i finançament dels béns i serveis públics locals. Les hisendes locals, tant a Catalunya com a la resta d'Espanya, pateixen diversos problemes. Dos són especialment rellevants per a aquesta tesi. El primer és la reduïda dimensió dels municipis, l'altre la seva insuficient dotació financera. A la tesi es tracten aquestes dues qüestions en cinc capítols. Primer s'introdueix la problemàtica, exposant-ne els antecedents, la situació actual i la metodologia per al seu anàlisi. A continuació s'aborda la relació entre la grandària dels municipis i la seva capacitat per a proveir béns i serveis públics. De manera recurrent es produeixen debats sobre els problemes que pateixen els municipis petits. El problema més evident d'aquests municipis és el dèficit de serveis públics. Es sol argumentar que els municipis petits pateixen aquests dèficits en la provisió de serveis públics a causa de la manca d'un nombre crític d'habitants. Normalment es presenta la consolidació municipal com a solució a aquest problema. En aquest treball analitzem les diferents vessants de la qüestió dels dèficits de serveis municipals. Es continua analitzant com influeix sobre el sector privat la incapacitat per part dels municipis de prestar la quantitat i/o qualitat correcta de béns i serveis públics. Sembla clar que l'atractiu d'un hotel per als seus clients depèn tant dels serveis que ofereix com de l'entorn en què es troba. Com s'ha dit sovint "un hotel de quatre estrelles necessita un entorn de quatre estrelles". Aquests atributs que configuren l'entorn són complementaris a l'oferta privada dels serveis hotelers i són essencials a l'hora de definir les opcions de comercialització, ja que sembla raonable que diferències en les dotacions de serveis públics, capital natural i imatge de la localitat generaran diferències en els preus d'hotels que altrament són idèntics. A la següent etapa s'estudia la situació financera a la qual s'enfronten els municipis a l'hora de proveir els béns i serveis públics, especialment en el cas de les localitats amb forta implantació de l'activitat turística. L'objectiu d'aquest estudi és doble. Primer, realitzar una anàlisi i un diagnòstic del finançament als municipis turístics i, segon, discutir diferents vies de millora. En una primera part s'exposa el marc que cal tenir en compte a l'hora de considerar les qüestions de provisió de serveis públics i els consegüents aspectes pressupostaris. Després es presenta un model estilitzat de provisió de béns públics i d'estructura pressupostària que explicita, amb la intenció de portar a terme l'anàlisi economètrica, les interrelacions rellevants entre provisió de serveis públics, ingressos fiscals i despeses. Tot seguit es presenten les dades que han de servir per a una anàlisi empírica que té dues vessants. Primer, estudiar si realment els municipis amb un fort pes de l'activitat turística presenten diferències en l'àmbit pressupostari i, segon, concretar quantificar en què consisteixen i de què depenen les diferències. El sisè apartat tracta la complementarietat entre béns i serveis públics des d'un marc normatiu, posant de manifest els aspectes que ha de tenir en compte un municipi turístic en les qüestions de provisió i finançament dels béns públics i que fan que tingui un comportament diferent d'un municipi no turístic. El penúltim apartat del treball inclou la discussió i l'avaluació d'algunes propostes correctores dels problemes detectats a l'anàlisi estadística i economètrica. El treball conclou amb un resum de les principals conclusions. La tesi conclou amb una discussió dels resultats obtinguts.

A proposal for the diagnosis of uncertain dynamic systems based on interval models

The performance of a model-based diagnosis system could be affected by several uncertainty sources, such as,model errors,uncertainty in measurements, and disturbances. This uncertainty can be handled by mean of interval models.The aim of this thesis is to propose a methodology for fault detection, isolation and identification based on interval models. The methodology includes some algorithms to obtain in an automatic way the symbolic expression of the residual generators enhancing the structural isolability of the faults, in order to design the fault detection tests. These algorithms are based on the structural model of the system. The stages of fault detection, isolation, and identification are stated as constraint satisfaction problems in continuous domains and solved by means of interval based consistency techniques. The qualitative fault isolation is enhanced by a reasoning in which the signs of the symptoms are derived from analytical redundancy relations or bond graph models of the system. An initial and empirical analysis regarding the differences between interval-based and statistical-based techniques is presented in this thesis. The performance and efficiency of the contributions are illustrated through several application examples, covering different levels of complexity.

Integració de sistemes estandarditzats de gestió: anàlisi empírica

Els sistemes de gestió permeten millorar l'eficiència de les organitzacions i en aquest context, una organització pot tenir implantats múltiples sistemes. La forma preferible de gestionar-los és integrant-los, perquè s'aprofiten les sinèrgies existents entre sistemes. Existeixen molt pocs estudis empírics que analitzin la integració de sistemes. Així, l'objectiu d'aquesta tesi és conèixer i analitzar empíricament com integren les empreses els sistemes i com realitzen les auditories d'aquests. Les conclusions de l'anàlisi empírica realitzada són que les empreses:(1)integren majoritàriament els sistemes a un determinat nivell, i sembla que els models de gestió utilitzats i l'ordre d'implantació dels sistemes, condicionen aquest nivell,(2)duen a terme, majoritàriament, auditories del sistema integrades, essent el nivell d'integració de les internes superior al de les externes, i(3)en alguns aspectes, sembla que la integració de les auditories externes, està relacionada amb el nivell d'integració dels sistemes.

Escola Mãe Hilda: um estudo sobre a pedagogia da (re)construção da identidade negra

RESUMO: Objetivo - apresentar o contributo da Escola Mãe Hilda para a afirmação da identidade afro-brasileira na população estudantil da Cidade do Salvador. Especificamente: a) conhecer os fundamentos pedagógicos-curricular da Escola Mãe Hilda; b) analisar os materiais didáticos utilizados pela Escola Mãe Hilda; c) apresentar as metodologias de trabalho da Escola Mãe Hilda. Metodologia - quanto ao percurso metodológico, em razão da questão básica desta dissertação, optou-se por realizar pesquisa qualitativa de natureza etnográfica, envolvendo uma abordagem empírica voltada para a abordagem de distúrbios identitários, em suas diversas dimensões na auto-estima de afro-descendentes. Foram estudados aspectos que envolvem o currículo, a sala de aula e atividades a que estão expostas as crianças da Escola Mãe Hilda. Resultados - examinando- se os conteúdos dos Cadernos de Educação do Ilê Aiyê como proposta pedagógica da Escola Mãe Hilda, observou- se que seus fudamentos dão ressignificação aos alunos, em termos de superação de distúrbios identitários, isto é , proporcionar o desenvolvimento e construção da identidade negra naqueles afro-descendentes, devido à valorização estética do universo cultural africano e afro-brasileiro, reconhecendo a África como uma das matrizes legítimas da cultura humana, em geral, e da brasileira, em particular. Conclusão- a pedagogia da (re) construção da identidade negra na Escola Mãe Hilda pode contribuir para a desconstrução dos distúrbios identitários; sendo assim, recomendada para escolas em Salvador-Bahia e em outras regiões do Brasil. ABSTRACT: Objective- study Escola Mãe Hilda (EMH - Mother Hilda School) contribution to the affirmation of an African-Brazilian identity in Bahia’s black student population. In particular: a) understand EMH’s pedagogical and curricula core; b) analyze teaching materials used at EMH; c) show EMH’s work methodology. Methodology- due to the very nature of this dissertation’s basic inquiry, ethnography in nature qualitative research targeted at identity disturbances in its various dimensions regarding African descendents self-esteem was performed. Aspects regarding EMH curriculum and classroom activities were studied. The choice of ethnography as an observation tool followed empirical analysis of whether Ilê Aiyê’s Educational Booklets as adopted by EMH aids students with identity disturbances and how it promotes the development of a black identity in those black descendants. Results- it has been observed that EMH utilizes methodological and pedagogical resources such as: story-telling, written reports, images, objects, dances, music, letters, myths, gestures, legends, craftsmanship, and clothing as vehicles to re-assign students self esteem, as well as, build their critical and self-aware knowledge of black descendants identity. Conclusion.- EMH pedagogical work, by encompassing various types of cultural and artistic expressions, as detailed in the aforementioned booklets, values African and Brazilian-African references. This aesthetic valuation therefore promotes an identity ressignification and the reintegration of the black descendent since it works within the symbolic and cultural universe of the African and African-Brazilian culture recognizing Africa as a legitimate matrix of human culture, in general, and of Brazilian in particular. Conclusively, EMH black identity (re)construction pedagogy can contribute to deconstruct identity disturbances; and as such, can be recommended to be adopted at other schools in Salvador, Bahia and other regions in Brazil.

The post-Lisbon role of the European Parliament in the EU's Common Commercial Policy: Implications for bilateral trade negotiations. EU Diplomacy Paper 05/2012, July 2012

This paper sets out to conduct an empirical analysis of the post-Lisbon role of the European Parliament (EP) in the EU’s Common Commercial Policy through an examination of the ‘deep and comprehensive’ bilateral Free Trade Agreements (FTAs) currently negotiated as part of the EU’s Global Europe strategy. The EU-Korea and EU-India FTAs are used as case studies in order to determine the implications of the EP’s enhanced trade powers on the processes, actors and outcomes of EU bilateral trade policy. The EP is now endowed with the ‘hard power’ of consent in the ratification phase of FTAs, acting as a threat to strengthen its ‘soft power’ to influence negotiations. The EP is developing strategies to influence the mandate and now plays an important role in the implementation of FTAs. The entry of this new player on the Brussels trade policy field has brought about a shift in the institutional balance of power and opened up the EP as a new point of access for trade policy lobbyists. Finally, increased EP involvement in EU trade policy has brought about a politicisation of EU trade policy and greater normative outcomes of FTAs.

'Does this compromise your design?' Interactionally producing a design concept in talk

How a design concept was interactionally produced in the talk-in-interaction between an architect and client representatives was studied. The empirical analysis was informed by ethnomethodology and conversation analysis to observe structures and patterns of talk that accomplished actions and practices of design. Some differences were observed between the properties of the design concept in comparison with the design ideas that were considered during these conversations. The design concept was observed to be significant for assessing why some moves in a design space were considered better than others. The importance of the design concept to these interactions raised more general questions about what a design concept is and how it can be described as an object type. With reference to studies of science, technology and society these concerns were provisionally engaged with and further study of the object properties of design concepts is suggested.

Inflation dynamics in the new EU member states: how relevant are external factors?

In this paper we evaluate the relative influence of external versus domestic inflation drivers in the 12 new European Union (EU) member countries. Our empirical analysis is based on the New Keynesian Phillips Curve (NKPC) derived in Galí and Monacelli (2005) for small open economies (SOE). Employing the generalized method of moments (GMM), we find that the SOE NKPC is well supported in the new EU member states. We also find that the inflation process is dominated by domestic variables in the larger countries of our sample, whereas external variables are mostly relevant in the smaller countries.

Predicting microbial pollution concentrations in UK rivers in response to land use change

The Water Framework Directive has caused a paradigm shift towards the integrated management of recreational water quality through the development of drainage basin-wide programmes of measures. This has increased the need for a cost-effective diagnostic tool capable of accurately predicting riverine faecal indicator organism (FIO) concentrations. This paper outlines the application of models developed to fulfil this need, which represent the first transferrable generic FIO models to be developed for the UK to incorporate direct measures of key FIO sources (namely human and livestock population data) as predictor variables. We apply a recently developed transfer methodology, which enables the quantification of geometric mean presumptive faecal coliforms and presumptive intestinal enterococci concentrations for base- and high-flow during the summer bathing season in unmonitored UK watercourses, to predict FIO concentrations in the Humber river basin district. Because the FIO models incorporate explanatory variables which allow the effects of policy measures which influence livestock stocking rates to be assessed, we carry out empirical analysis of the differential effects of seven land use management and policy instruments (fiscal constraint, production constraint, cost intervention, area intervention, demand-side constraint, input constraint, and micro-level land use management) all of which can be used to reduce riverine FIO concentrations. This research provides insights into FIO source apportionment, explores a selection of pollution remediation strategies and the spatial differentiation of land use policies which could be implemented to deliver river quality improvements. All of the policy tools we model reduce FIO concentrations in rivers but our research suggests that the installation of streamside fencing in intensive milk producing areas may be the single most effective land management strategy to reduce riverine microbial pollution.

A variable radius niching technique for speciation in genetic algorithms

In this paper, a continuation of a variable radius niche technique called Dynamic Niche Clustering developed by (Gan & Warwick, 1999) is presented. The technique employs a separate dynamic population of overlapping niches that coexists alongside the normal population. An empirical analysis of the updated methodology on a large group of standard optimisation test-bed functions is also given. The technique is shown to perform almost as well as standard fitness sharing with regards to stability and the accuracy of peak identification, but it outperforms standard fitness sharing with regards to time complexity. It is also shown that the technique is capable of forming niches of varying size depending on the characteristics of the underlying peak that the niche is populating.
