Political intervention in economic activity
Creators: name: Gilles, Enrique
Publisher: name: Universidad del Rosario
Year: 2022

description: This paper proposes a political economy explanation of bailouts to declining industries. A model of probabilistic voting is developed, in which two candidates compete for the vote of two groups of the society through tactical redistribution. We allow politicians to have core support groups they understand better, this implies politicians are more or less effective to deliver favors to some groups. This setting is suited to reproduce pork barrels or machine politics and patronage. We use this model to illustrate the case of an economy with both an efficient industry and a declining one, in which workers elect their government. We present the conditions under which the political process ends up with the lagged-behind industry being allowed to survive.

Mixed oligopoly in education
Creators: name: Maldonado, Dario
name: Cremer, Helmuth
Publisher: name: Universidad del Rosario
Year: 2013

description: This paper studies oligopolistic competition in education markets when schools can be private and public and when the quality of education depends on ìpeer groupî e§ects. In the Örst stage of our game schools set their quality and in the second stage they Öx their tuition fees. We examine how the (subgame perfect Nash) equilibrium allocation (qualities, tuition fees and welfare) is a§ected by the presence of public schools and by their relative position in the quality range. When there are no peer group e§ects, e¢ ciency is achieved when (at least) all but one school are public. In particular in the two school case, the impact of a public school is spectacular as we go from a setting of extreme di§erentiation to an e¢ cient allocation. However, in the three school case, a single public school will lower welfare compared to the private equilibrium. We then introduce a peer group e§ect which, for any given school is determined by its student with the highest ability. These PGE do have a signiÖcant impact on the results. The mixed equilibrium is now never e¢ cient. However, welfare continues to be improved if all but one school are public. Overall, the presence of PGE reduces the e§ectiveness of public schools as regulatory tool in an otherwise private education sector.
Publicness of goods and violent conflict : evidence from Colombia
Creators: name: Montolio, Daniel
name: Cortes, Darwin
Publisher: name: Universidad del Rosario
Year: 2022

description: How the degree of publicness of goods affect violent conflict? Based on the theoretical model in Esteban and Ray (2001) we find that the effect of the degree of publicness depends on the group size. When the group is small (large), the degree of publicness increases (decreases) the likelihood of conflict. This opens an empirical question that we tackle using microdata from the Colombian conflict at the municipality level. We use three goods with different publicness degree to identify the sign of the effect of publicness on conflict. These goods are coca crops (private good), road density (public good subject to congestion) and average education quality (a purer public good). After dealing with endogeneity issues using an IV approach, we find that the degree of publicness reduces the likelihood of both paramilitary and guerrilla attacks. Moreover, coca production exacerbates conflict and the provision of both public goods mitigates conflict. These results are robust to size, geographical, and welfare controls. Policies that improve public goods provision will help to fight the onset of conflict.
Labour market, international trade, and unemployment in a less developed country
Creators: name: Mesa, Fernando
Publisher: name: Universidad del Rosario
Year: 2011

description: This paper constructs a trade general equilibrium model for a less developed country with three sectors. One is the informal and un-tradable sector characterized by áexible wages, while the other two sectors are tradable, export and import sectors. The model imposes a binding minimum wage over the unskilled labour and e¢ cient wage distortions on the skilled labour. Comparative statics is driven to analyze the e§ects on the labour market as consequence of opening the economy, raising the minimum wage and the introduction of an augmenting productivity in the export sector.
METHODS OF TEACHING FOREIGN LANGUAGES FOR EFL LEARNERS

Publisher: name: Zenodo
Year: 2024

description: This article talks about the methodology of teaching foreign languages in Uzbekistan. The author, relying on philological data and written sources, studied the existing peculiarities on the subject, which made clarifications on the basis of existing scientific literature. The article presented four methods of learning foreign languages: the grammar and translation method, the direct method, the audiolingual method, and the communicative method. Each method has been described in terms of its characteristics and approaches to language teaching. Opinions from linguists have been included to offer a critical view on each method. The grammar and translation method emphasizes reading and writing, the direct method focuses on oral communication and natural language acquisition, the audiolingual method values repetition and memorization, while the communicative method values meaningful communication and social interaction. From the presentation of the methods and the opinions of linguists, it was possible to understand the implications of each method in the teaching of foreign languages.
Modelling the monetary policy reaction function of the Colombian Central Bank
Creators: name: Ramírez Gómez, Manuel
name: Otero, Jesus
Publisher: name: Universidad del Rosario
Year: 2008

description: This paper proposes a simple Ordered Probit model to analyse the monetary policy reaction function of the Colombian Central Bank. There is evidence that the reaction function is asymmetric, in the sense that the Bank increases the Bank rate when the gap between observed inflation and the inflation target (lagged once) is positive, but it does not reduce the Bank rate when the gap is negative. This behaviour suggests that the Bank is more interested in fulfilling the announced inflation target rather than in reducing inflation excessively. The forecasting performance of the model, both within and beyond the estimation period, appears to be particularly good.

Profundización, apertura y cierre de mercados de exportación a nivel sectorial en Colombia : una estimación de los márgenes del comercio y su relación con el ciclo económico
Creators: name: Valderrama González, Daniel

Publisher: name: Universidad del Rosario
Year: 2022

description: En este trabajo se explora, desde el punto de vista empírico, el comportamiento de la profundización, apertura y cierre de mercados de exportación a nivel sectorial para Colombia durante el periodo 1997- 2010, con énfasis en los dos periodos de recesión que presenta la economía durante el mismo. Para ello se emplea una metodología de descomposición de los cambios registrados por el comercio, en sus márgenes intensivo y extensivo, que permite la identificación de estos fenómenos y su observación tanto a lo largo del tiempo como a nivel transversal. Los resultados indican que, en el corto plazo, el margen intensivo del comercio explica la mayor parte de las variaciones en las exportaciones, en tanto que en el mediano plazo se encuentra una importante contribución del margen extensivo a éstas. Adicionalmente, desde el punto de vista sectorial, la crisis de 1997-1999 no presenta un patrón homogéneo en términos del comportamiento de los márgenes del comercio, en tanto que la de 2008- 2009 se caracteriza por presentar un patrón más homogéneo a través de los distintos sectores de la actividad económica.
An analysis of the relationship between wages in the public and private sector in colombia : a panel data approach
Creators: name: Garcia-Suaza, Andres

Publisher: name: Universidad del Rosario
Year: 2022

description: This document examines the time-series properties of the wage differentials that arise between the public and private sector in Colombia during the sample period 1984 to 2005. We Find conflicting results in unit-root and stationary tests when looking at wage differentials at an aggregate level (such as for men, women or both). However, when we analyse wage differentials at higher levels of disaggregation, treat them jointly as a panel of data, and allow for the presence of potential cross section dependence, there is more supportive evidence for the view that wage differentials are stationary. This implies that although wage differentials do exist, they have not been consistently increasing (or decreasing) over time.

Poverty impacts of increased openness and fiscal policies in a dollarized economy: a CGE-micro approach for Ecuador
Creators: name: Rivera, Ketty
name: Wong, Sara
name: Arguello, Ricardo
Publisher: name: Universidad del Rosario
Year: 2007

description: We quantify the effects on poverty and income distribution in Ecuador of bilateral trade liberalization with the US and a budget-neutral value added tax increase which seeks to compensate tariff revenue losses. We stress the study of fiscal policies that the government could tap in order to compensate for tariff revenue loss. This is a very important issue for Ecuador because this country adopted the US dollar as its currency in 2000, forgiving the use of important policy instruments. To study these issues we combine a reduced-form micro household income and occupational choice model (using 2005/6 data from the Ecuadorian LSMS) with a standard single-country computable general equilibrium model (employing a 2004 SAM). We follow a sequential approach that simulates the full distributional impact of trade and tax policies. We find that the impact of these policy changes on extreme poverty and income distribution is small but positive.
Natural disasters and clientelism: the case of floods and landslides in Colombia
Creators: name: Gallego, Jorge A.
Publisher: name: Universidad del Rosario
Year: 2015

description: What are the effects of natural disasters on electoral results? Some authors claim that catastrophes have a negative effect on the survival of leaders in a democracy because voters have a propensity to punish politicians for not preventing or poorly handling a crisis. In contrast, this paper finds that these events might be beneficial for leaders. Disasters are linked to leader survival through clientelism: they generate an in-flow of resources in the form of aid, which increase money for buying votes. Analyzing the rainy season of 2010-2011 in Colombia, considered its worst disaster in history, I use a difference-in-differences strategy to show that in the local election incumbent parties benefited from the disaster. The result is robust to different specifications and alternative explanations. Moreover, places receiving more aid and those with judicial evidence of vote-buying irregularities, are more likely to reelect the incumbent, supporting the mechanism proposed by this paper.

The ECHELON Trail: An Illegal Vision
Creators: name: Wright, Steve
Publisher: name: figshare
Year: 2015
Subjects: subject: Information Systems
subject: FOS: Computer and information sciences

description: This article tells the story behind the uncovering of the US operated global telecommunications interceptions system now known as ECHELON. It begins with the use of fieldwork techniques in the early 1970's exploring the configuration of Britain's Post Office Towers – these were ostensibly the microwave links through which Britain's long distance telephone calls were made. This modelling process revealed a system within the system of microwave towers linked to the American Base of Menwith Hill in the North York Moors. All the key researchers were then promptly arrested, a raid by Special Branch on the author's university at Lancaster ensued and later a show trail for the other main researchers, most notably Duncan Campbell. Eventually in 1988, Duncan wrote up the ECHELON story, which for its time was an incredible piece of detective work using materials lifted from waste bins by the women activists campaigning around the Menwith Hill Base. Little notice was taken until 1997 when an obscure book by Nicky Hager, Secret Power explained the role and function of ECHELON in more depth. The author represented these findings in a policy report to the European Parliament on the technology of political control that led to a process of political debate and disagreement of the ethics of such a system which continues even today.
Media bias and central bank response. Evidence from the nominal exchange rate behavior in Colombia
Creators: name: Taborda, Rodrigo
Publisher: name: Universidad del Rosario
Year: 2011

description: Since 1991 Colombia has had a market-determined Peso - US Dollar Nominal Exchange Rate (NER), after more than 20 years of controlled and multiple exchange rates. The behavior (revaluation / devaluation) of the NER is constantly reported in news, editorials and op-eds of major newspapers of the nation with particular attention to revaluation. The uneven reporting of revaluation episodes can be explained by the existence of an interest group particulary affected by revaluation, looking to increase awareness and sympathy for help from public institutions. Using the number of news and op-eds from a major Colombian newspaper, it is shown that there is an over-reporting of revaluation episodes in contrast to devaluation ones. Secondly, using text analysis upon the content of the news, it is also shown that the words devaluation and revaluation are far apart in the distribution of words within the news; and revaluation is highly correlated with words related to: public institutions, exporters and the need of assistance. Finally it is also shown that the probability of the central bank buying US dollars to lessen revaluation effects increases with the number of news; even though the central bank allegedly intervenes in the exchange rate market only to tame volatility or accumulate international reserves.

description: Who did it? Attribution is fundamental. Human lives and the security of the state may depend on ascribing agency to an agent. In the context of computer network intrusions, attribution is commonly seen as one of the most intractable technical problems, as either solvable or not solvable, and as dependent mainly on the available forensic evidence. But is it? Is this a productive understanding of attribution? — This article argues that attribution is what states make of it. To show how, we introduce the Q Model: designed to explain, guide, and improve the making of attribution. Matching an offender to an offence is an exercise in minimising uncertainty on three levels: tactically, attribution is an art as well as a science; operationally, attribution is a nuanced process not a black-and-white problem; and strategically, attribution is a function of what is at stake politically. Successful attribution requires a range of skills on all levels, careful management, time, leadership, stress-testing, prudent communication, and recognising limitations and challenges.

We stress the importance of statistical testing in interpreting the measure of systemic importance. An empirical application illustrates the testing procedures, using equity data for three European banks.

description: La decisión de los individuos acerca del ahorro para el retiro ha sido abordada teóricamente bajo la hipótesis de que el sistema de seguridad social se comporta como un sustituto de otros mecanismos de ahorro. Este documento presenta evidencia de los patrones y determinantes del ahorro para el retiro en Colombia a partir de la Gran Encuesta Integrada de Hogares de 2007. Los resultados muestran que el 63% de los ocupados declaran no ahorrar para su vejez. A partir de modelos de selección discreta se encuentra que individuos jóvenes, de sexo masculino, con menor nivel educativo, residentes en zonas rurales, y trabajadores cuenta propia, presentan menores probabilidades de ahorrar para el retiro; además las características socioeconómicas resultan significativas en la determinación del mecanismo de ahorro utilizado.

description: The emergence of antibiotic resistant Staphylococcus aureus presents a worldwide problem that requires non-antibiotic strategies. This study investigated the anti-biofilm and anti-hemolytic activities of four red wines and two white wines against three S. aureus strains. All red wines at 0.5–2% significantly inhibited S. aureus biofilm formation and hemolysis by S. aureus, whereas the two white wines had no effect. Furthermore, at these concentrations, red wines did not affect bacterial growth. Analyses of hemolysis and active component identification in red wines revealed that the anti-biofilm compounds and anti-hemolytic compounds largely responsible were tannic acid, trans-resveratrol, and several flavonoids. In addition, red wines attenuated S. aureus virulence in vivo in the nematode Caenorhabditis elegans, which is killed by S. aureus. These findings show that red wines and their compounds warrant further attention in antivirulence strategies against persistent S. aureus infection.
Productivity growth in electric energy retail in Colombia. A bootstrapped malmquist indices approach
Creators: name: Taborda, Rodrígo
name: Santamaría, Julieth
Publisher: name: Universidad del Rosario
Year: 2011

description: This paper offers a productivity growth estimate for electric energy commercialization firms in Colombia, using a non-parametric Malmquist bootstrap methodology. The estimation and methodology serve two main purposes. First, in Colombia Commercialization firms are subject to a price-cap regulation scheme, a non-commonarrangement in the international experience for this part of the industry. Therefore the paper’s result suggest an estimate of the productivity factor to be used by the regulator, not only in Colombia but in other countries where commercialization is a growing part of the industry (renewable energy, for instance). Second, because of poor data collection from regulators and firms themselves, regulation based on a single estimation of productivity seems inappropriate and error-prone. The nonparametric Malmquist bootstrap estimation allows an assessment of the result in contrast to a single one estimation. This would open an opportunity for the regulator to adopt a narrower and more accurate productivity estimation or override an implausible result and impose a productivity factor in the price-cap to foster the development of the industry.
Poor people and risky business
Creators: name: Zuleta, Hernando
Publisher: name: Universidad del Rosario
Year: 2022

description: We try to explain why economic conflicts and illegal business often take place in poor countries. We use the concept of subsistence level of consumption (d) and assume a regular concave utility function for consumption levels higher than d. For consumption levels lower than d utility is constant and equal to zero. Under this framework poor agents are risk-lovers. This result helps to explain why economic conflicts are more likely to appear in poor economies and why poor agents are more willing to undertake illegal business.
Verb stem alternation in Pangwa Tangsa

Publisher: name: La Trobe
Year: 2023

description: Tangsa is a very linguistically diverse group spoken on the India-Myanmar border, with around 80 distinct and named varieties, many of which are mutually intelligible but many of which are not. In Myanmar, the Tangsa sub-tribes are grouped under Tangshang Naga.
This paper examines and exemplifies the phenomneon of verb stem alternation, whereby a single verb has two stems, a verbal stem, which is demonstrated to be the ‘base’ or underived form, and a nominal stem which has different form, most frequently a different tone category.
As with other Tibeto-Burman languages, both the forms and the functions of the stem alternations in the Tangsa varieties show considerable diversity. In the Tangsa varieties treated here, one of the stems, which we term the verbal form, is clearly the underived root and the alternate stem is derived from it. The most frequent way of forming an alternate stem is a change of tone category, keeping the vowel and any final consonants the same. In multiple cases in one Tangsa variety there is an alternate stem carrying a different form, and in a related variety there is no alternation between the stems.
The verbal and nominal stems for 151 roots in the Mueshaung and Ngaimong varieties will be compared, and the findings of this comparison will be enhanced by observations of stem alternation from other Tangsa varieties.

Engaging millennials with online content delivery through a discourse community understanding of learning
Creators: name: Bridge, Christopher
Publisher: name: La Trobe
Year: 2023

description: Short videos are now a standard feature of online content delivery and a wealth of literature has emerged regarding best practice in designing for student engagement. In this concise paper we argue that lessons from research on engaging with ‘millennial’ students in general can also be applied constructively to video design. In particular this generation of students has been shown to desire a personal connection with their teachers, they expect educators to be ‘passionate’ or ‘enthusiastic’ about the topic, and they demand a line-of-sight connection between the immediate learning activity and the end-goal. Furthermore, we argue that an understanding of transition to university studies which conceives of disciplines as discourse communities provides an integrative understanding of student engagement that further informs the design of effective video vignettes. We describe a set of videos, in which teaching academics describe their research to students in a core first-year Bachelor of Science subject, which have been produced according to the principles derived from the above research and approach, with the aim of attaining a high level of student engagement. These videos have recently been trialled and are soon to be evaluated.
Land Reform, Latifundia and Social Development at Local Level in Colombia, 1961-2010

description: The paper analyzes the effects of land reform on social development – poverty and land distribution-at the local level. Land reform in Colombia, understood as the allocation of public land to peasant, has granted 23 million hectares which comprises around 20% of Colombian territory and about 50% of usable productive land. Theoretically, the net impact of land reform on development is the combination of a poverty effect and a land distribution effect. Our findings suggest that land reform from 1961 onwards has slightly reduced poverty and mildly improved land distribution. Nonetheless,municipalities with strong presence of latifundia prior to1961 have experienced both a slower drop in poverty and a weaker improvement of land distribution .This paper finds that prevalence of latifundia partially offset the positive effect of land reform in promoting social development.
Job satisfaction in a developing country: exploring the work-family rivalry

Year: 2011

description: This paper empirically analyzes the relationship between familiar duties and job satisfaction in a developing country by using four different indexes. This analysis includes objective measures and subjective measures from data gathered in Colombia. In contrast to previous literature, objective measures are included through the interactive effects between the family responsibilities variables and the gender. Subjective measures are evaluated using the job-family compatibility perception. Our findings show that women tend to be less satisfied at work as the number of children increases, while men are more prone to satisfaction at work when they are single thus showing the importance given to the use of their own time. It also reveals that job-family compatibility is an important determinant of job satisfaction.

Year: 2007

description: El presente trabajo busca encontrar posibles conexiones entre la vivienda y el análisis de seguridad. Los avances en la teoría de la seguridad han permitido la inclusión de nuevos aspectos señalados como posibles amenazas que ameritan ser considerados dentro de la óptica de seguridad. En esta perspectiva, el tema de seguridad humana cobra fuerza y permite un análisis multidimensional incluyendo aspectos como la seguridad económica y la seguridad ambiental. En este nuevo marco, la vivienda puede encontrar un espacio para complementar el análisis de inseguridad económica, asociado a la pobreza y calidad de vida y al análisis de inseguridad ambiental vinculada a los desastres naturales y el entorno en que se ubican las viviendas. Al final se concluye que, si bien el análisis puede hacerse, el paso real hacia la securitización de estos temas exige un compromiso enorme del Estado para enfrentar el tema al nivel de una amenaza.

description: El diseño del sistema de seguridad social en salud y su efectiva implementaciónes uno de los más grandes retos de la sociedad, y a su vez es la principal garantía del goce efectivo del derecho a la salud. Un gran desafío de estos sistemas es la administración del riesgo financiero implícito en la provisión de los servicios de salud. Este documento ilustra en qué medida este desafío se puede enmarcar dentro de un problema de administración cuantitativa de los riesgos financieros. Si bien el uso de estas herramientas no son nuevas en el diseño del sistema de seguridad social en salud colombiano, es importante dar claridad sobre el alcance que han tenido estas herramientas, las posibles mejoras que se puedan hacer y los desafíos, en la gestión de estos riesgos, implícitos en la reforma actual de la institucionalidad del sistema.

Diverse students and lecture recording technology: can lecture recording replace lectures?
Creators: name: Musarrat, Maimuna

Publisher: name: La Trobe
Year: 2023

description: CONTEXT
Higher education students are increasingly coming from diverse backgrounds – e.g. mature aged professionals studying to further develop their career and/or students who live farther away from the campus. As a result, universities are moving away from the traditional teaching methods and introducing different technology and teaching approaches to accommodate the needs of diverse students. Lecture recording (LR) technology is one such technology that has been widely accepted by universities in Australia in the recent years. While LR serves various purpose, one of the main reasons universities have been using this technology is to accommodate students who can’t attend the lectures. However, whether lecture recording technology is actually beneficial for students is a widely debated topic.
PURPOSE
This paper is part of a wider research which investigates the enablers and barriers to the acceptance of educational technology by academics in Australian Higher Education Context. This paper summarises the findings from this research on lecture recording and its impact on various aspects of students.
APPROACH
A qualitative approach was taken to undertake this research. The research was conducted using focus groups with academics at Swinburne University of Technology in April to June 2014 – during the first semester of automated LR at the university. Academics were invited to participate in the focus groups and four focus groups were conducted with eleven participants in total. The focus groups were then transcribed, and the transcriptions were analysed using a thematic analysis approach with the help of NVivo.
RESULTS
Although literature suggest that lecture recording impacts student attendance negatively, findings from this research show that there is little evidence behind it. The majority opinion is that student attendance can be low for a number of reasons and it can not be linked directly to one factor like the LR.
CONCLUSIONS
Students with diverse needs often are faced with limited options regarding lecture attendance and LR is an important tool that allows them to review lecture materials without attending the lectures. Although LR is here to stay, and students from diverse backgrounds continue to benefit from LR technology, not all lecturers are convinced that it provides sufficient benefit to the student and/or lecturers.
On the exhaustiveness of truncation and dropping strategies in many-to-many matching markets

Publisher: name: Universidad del Rosario
Year: 2012

description: We consider two–sided many–to–many matching markets in which each worker may work for multiple firms and each firm may hire multiple workers. We study individual and group manipulations in centralized markets that employ (pairwise) stable mechanisms and that require participants to submit rank order lists of agents on the other side of the market. We are interested in simple preference manipulations that have been reported and studied in empirical and theoretical work: truncation strategies, which are the lists obtained by removing a tail of least preferred partners from a preference list, and the more general dropping strategies, which are the lists obtained by only removing partners from a preference list (i.e., no reshuffling). We study when truncation / dropping strategies are exhaustive for a group of agents on the same side of the market, i.e., when each match resulting from preference manipulations can be replicated or improved upon by some truncation / dropping strategies. We prove that for each stable mechanism, truncation strategies are exhaustive for each agent with quota 1 (Theorem 1). We show that this result cannot be extended neither to group manipulations (even when all quotas equal 1 – Example 1), nor to individual manipulations when the agent’s quota is larger than 1 (even when all other agents’ quotas equal 1 – Example 2). Finally, we prove that for each stable mechanism, dropping strategies are exhaustive for each group of agents on the same side of the market (Theorem 2), i.e., independently of the quotas.

description: When allocating a resource, geographical and infrastructural constraints have to be taken into account. We study the problem of distributing a resource through a network from sources endowed with the resource to citizens with claims. A link between a source and an agent depicts the possibility of a transfer from the source to the agent. Given the supplies at each source, the claims of citizens, and the network, the question is how to allocate the available resources among the citizens. We consider a simple allocation problem that is free of network constraints, where the total amount can be freely distributed. The simple allocation problem is a claims problem where the total amount of claims is greater than what is available. We focus on consistent and resource monotonic rules in claims problems that satisfy equal treatment of equals. We call these rules fairness principles and we extend fairness principles to allocation rules on networks. We require that for each pair of citizens in the network, the extension is robust with respect to the fairness principle. We call this condition pairwise robustness with respect to the fairness principle. We provide an algorithm and show that each fairness principle has a unique extension which is pairwise robust with respect to the fairness principle. We give applications of the algorithm for three fairness principles: egalitarianism, proportionality and equal sacrifice.

description: El objetivo de este trabajo es contribuir a identificar el efecto de las remesas que envían los emigrantes a sus comunidades de origen en México. Del mismo modo, se estudia el efecto que la participación de la mujer tiene en este proceso. La fuente de información es el Consejo Nacional de Población de México CONAPO y contiene variables a nivel estatal y municipal para el año 2000. La base de datos contiene índices de desarrollo humano, intensidad migratoria y remesas para los 2443 municipios mexicanos. La evidencia empírica sugiere que las remesas tienen un impacto positivo sobre los niveles de desarrollo de las comunidades receptoras. No obstante, la relación entre remesas y desarrollo es no lineal. Adicionalmente, se encontró que el efecto positivo que tienen las remesas sobre el desarrollo es más alto cuando la cabeza de familia de los hogares receptores es mujer.

description: The successful design of case-based reasoning(CBR) systems depends chiefly on high-efficiency retrieval strategy of case library. In this paper, the author focuses on an original case retrieval approach using Tabu Search(TS) method. TS is a meta-heuristic approach designed skillfully for finding a suboptimal solution of combinational optimization problems. It is shown how this method can be used to speed up the case retrieval. The preliminary results obtained by our approach let us conclude that TS is a robust and promising technique to be applied into CBR.

Poverty impacts of agricultural policy adjustments in an opening economy: the case of Colombia

description: We aim to contribute to the assessment of poverty impacts on the rural sector arising from agricultural policy adjustments in Colombia. For this we use an agriculture specialized static CGE model, jointly (sequentially) with a microsimulation model that allows for effective job relocation. Results indicate that the sectoral impact of the program implemented tends to be small and has considerable variability across crops. They also show that the highest impacts come from the irrigation and land improvements component of the program. Lastly, although it reduces poverty, poverty impacts are small and tend to concentrate in rural households toward the middle of the income distribution ladder.

description: Dialkyl 2,2′-bipyridyl-4,4′-dicarboxylate (Lβn, where βn refers to the number of carbons in β-substituted alkyl chain) complexes including PtLβ16Cl2, CdLβ16Cl2, [AgLβnNO3] and the dodecylsulfate salt [AgLβn2](DOS) were produced at reduced cost and in shorter times, compared to traditional solvent-based methods, by mechanochemical reaction in the absence of solvent. PtLβ16Cl2 and the [AgLβn2](DOS) complexes are the first mesogenic transition metal complexes to be produced via ball milling. The effectiveness of a simple ligand modification, β- versus α-attachment of the alkyl functionalities to the ligand, is presented as a highly effective method for increasing the stable temperature range of a variety of metallomesogens and for producing sub-room-temperature liquid crystals.
Partial decentralization as a safeguard against favoritism

Publisher: name: Universidad del Rosario
Year: 2010

description: In this paper I investigate the optimal level of decentralization of tasks for the provision of a local public good. I enrich the well-known trade-off between internalization of spillovers (that favors centralization) and accountability (that favors decentralization) by considering that public goods are produced through multiple tasks. This adds an additional institutional setting, partial decentralization, to the classical choice between full decentralization and full centralization. The main results are that partial decentralization is optimal when both the variance of exogenous shocks to electorate’s utility is large and the electorate expects high performance from politicians. I also show that the optimal institutional setting depends on the degree of substitutability / complementarity between tasks. In particular, I show that a large degree of substitutability between tasks makes favoritism more likely, which increases the desirability of partial decentralization as a safeguard against favoritism.

description: Animal fibers are fibers obtained from the hair or fur of animals, and are used in textile production to create a wide range of products such as clothing, carpets, and upholstery. Animal fibers are protein based, the complex material which most of animal body is made of. The most common animal fibers used in textile production are wool, alpaca, mohair, cashmere, camel hair, llama, angora, yak, qiviut, and vicuna. The term ‘specialty fiber’ denotes animal fibers used in textiles other than the wool grown by sheep. These fibers include cashmere, mohair, qiviut (musk ox), alpaca, llama, vicuna, guanaco, Bactrian camel, yak, bison, and angora (rabbit), which are generally acknowledged to have special properties of softness, smoothness, and lustre, when compared with sheep wool.
Parametric pension reform and the intensive margin of labor supply, evidence from Colombia

description: We analyze the effect of a parametric reform of the fully-funded pension regime in Colombia on the intensive margin of the labor supply. We take advantage of a threshold defined by law in order to identify the causal effect using a regression discontinuity design. We find that a pension system that increases retirement age and the minimum weeks during which workers must contribute to claim pension benefits causes an increase of around 2 hours on the number of weekly worked hours; this corresponds to 4% of the average number of weekly worked hours or around 14% of a standard deviation of weekly worked hours. The effect is robust to different specifications, polynomial orders and sample sizes.
Ownership structure and risk at Colombian banks
Creators: name: Ramírez Gómez, Manuel

description: The separation between ownership and the control of capital in banks generates differences in the preferences for risk among shareholders and the manager. These differences could imply a corporate governance problem in banks with a dispersed ownership, since owners fail to exert control in the allocation of capital. In this paper we examine the relationship between the ownership structure and risk for Colombian banks. Our results suggest that a high ownership concentration leads to higher levels of risk.
