Citizen safety at local level: fieldwork notes on performance and perception of the ‘Quadrant Plan’ in Cali (Colombia)

This article summarizes field notes related to the study of the actions performed by the Metropolitan Police of Santiago de Cali in the context of its ‘Plan Cuadrante’ (a micro-local security action plan) and the citizen’s perception towards it. Taking an ethnographic approach, it places special emphasis on the actions that imply identifying the main criminal and violent actors and activities. The study focuses on four local districts of the city: El Cortijo, Mariano Ramos, Terrón Colorado y Villa del Lago.

Frequency of Low-level Mosaicism in X-Cromosome in Couples with Antecedent of Recurrent Miscarriages

Recurrent miscarriage occurs in around 1 to 7 percent of couples. The etiology involves genetic, immunologic, anatomic, hormonal, metabolic, thrombophilic and infectious factors. With the aim of establishing the frequency of low-level mosaicism in the X-chromosome, in a population of couples with prior recurrent miscarriages, a prospective case-control cytogenetic study took place on 20 couples, at the biogenetic laboratory in CECOLFES (Colombian Center of Fertility and Sterility). Clinical pathologic evaluation, anatomic, hormonal, infectious, andrologic and genetic studies were performed. As a conventional method in cytogenetic techniques, banding GTG was used for the study of structural and numeric chromosomal abnormalities whereas the molecular method of Fluorescence In Situ Hybridization (FISH) was used to confirm the mosaicism in sexual chromosomes. According to paraclinic results from the participating couples, diagnosis showed immunologic (75%), anatomic (30%), hormonal (25%), male (25%), infectious (25%), genetic (15%) and idiophatic factors (10%). Results from the cytogenetic analysis, were 10% of low-level mosaicism in the X-chromosome in two women whose final diagnosis included genetic and infectious factors for one and genetic and immunologic factors for the other. Only 10 % of the total miscarriages from the couples were evaluated. Conclusions include aspects such as multifactorial evidence of pathogenesis in recurrent miscarriage, the sub-diagnosis of genetic factors and the need to focus future investigations on cytogenetic interpretation and the clinicalpathological association between low-level mosaicism in the X-cromosome and recurrent miscarriage.

ControlFluid: un mercado variable

Las estrategias de una empresa en un mercado pequeño donde hay pocos compradores y muchos vendedores se vuelven el centro y punto clave de éxito, de lo contrario la empresa solo sigue una tendencia de mercado que al mediano plazo no resultara efectiva y terminan desapareciendo. Es por ello que las estrategias de mercado en las empresas se vuelven la característica diferenciadora permitiendo tomar ventaja del hacinamiento de un sector. Para que una empresa sea exitosa debe tener en cuenta sus ventajas competitivas y potencializarlas al máximo según las condiciones del mercado en el que se desempeña, ya sean estas de estructura, recursos o talento humano. El estudio de caso pretende abordar las dinámicas de un mercado específico con tendencias particulares que definen la forma de competir y las costumbres de sus principales actores. Estas mismas tendencias fijan los modelos de negocio en el sector, que desde diversos análisis como el PESTEL o puntos de vista de autores como Kotler (1992) y sus estrategias competitivas según la participación de mercado o Miller (1986) y sus definiciones de mercados o Porter (1980) con sus fuerzas de mercado, lo que permite dar una guía o explicación del porqué de las situaciones particulares del mercado en un sector tan especifico como el de automatización y control de calidad.

Job satisfaction in a developing country: exploring the work-family rivalry

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.

Land Reform, Latifundia and Social Development at Local Level in Colombia, 1961-2010

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.

A firm-level analysis of ICT adoption in an emerging economy: evidence from the colombian manufacturing industries

This study examines ICT adoption among 3,759 Colombian manufacturing firms, and attempts to identify the factors that are conducive to the adoption and usage of ICT at the firm level. Our major findings are (i) that the adoption of a given information and communication technology is better facilitated when a firm is relatively large, has large human capital, engages in more innovative activities, and when a firm’s organizational structure is better aligned with the given technology; (ii) that positive associations between the key determinants and ICT adoptions are more pronounced for small and medium-sized firms than for large ones, and (iii) that information spillovers within industries is also a determinant of ICT adoptions by the firms.

Factor shares at the sector level, Colombia 1990-2005

In general, empirical studies on economics rely on the assumption of constant capital share of income both at the aggregate level and at the sector level. However, there is no empirical evidence supporting the constancy of capital share at the sector level. In this paper, using Colombian data, we measure capital share for 48 sectors during the period 1990-2005. We also explore the relation between capital's share and factor prices and the behavior of capital share during the business cycle. The main results are the following: (i) capital share is not constant but, rather, has an increasing trend; (ii) capital shares growth rates positively correlate with sector value-added growth; (iii) the capital shares behave pro-cyclically; and (iv) there is a positive correlation between capital shares and real wages and a negative correlation between capital shares and interest rates. These results suggest that the usual assumption of constant factor shares is not accurate.

Information externalities and export trade duration at the firm level

Recent empirical work emphasizes the importance of the extensive margin of trade (new exporters, new export activities) for long run export growth. In this context, understanding the determinants of duration of new exporters is key for underpinning the dynamics of exports growth. As new exporters tend to show low survival rates, identifying the determinants of export duration is highly relevant for academic and policy purposes. In this paper, we explore whether information externalities arising from different levels of spatial interaction allow new exporters to increase the duration of their trade activities. For this, we use transaction level data on Colombian exports between 2004 and 2011. Results show that export networks, understood as the agglomeration of exporting firms at different spatial levels, reduce the risk of dropping out from exporting and that this effect is stronger the more similar are export activities carried out by firms

An Empirical Examination of the Determinants of Foreign Direct Investment: A Firm-Level Analysis for the Colombian Economy

We use a large firm level data set to investigate the determinants of foreign direct investment(FDI) in Colombia. We estimate econometric models for the determinants of the probabilitythat a firm receives FDI, as well as for the factors that help to explain the foreign share in afirm’s capital. The results show that firms listed on the stock market, involved in foreign tradeactivities, and operating in sectors with greater capital intensity are more likely to be recipientsof FDI. Also, the probability of a firm receiving FDI is directly related to its size.
