    The Relationship between Perceptions of Insecurity, Social Capital and Subjective well-being: Empirical Evidences from Conflicted Rural Colombia
    (Universidad de los Andes, 2010) Wills Herrera, Eduardo; Orozco Collazos, Luz Elena; Forero Pineda, Clemente; Pardo Aragón, Oscar Armando; Andonova Zuleta, Veneta Stefanova
    Subjective Wellbeing -SWB-, the evaluation people do of their lives, has been proposed as a measure to track the development of communities instead of economic growth. As part of a more general research question in which we tested the impact of subjective insecurity on the choice of hybrid organizational modes, we hypothesized that subjective insecurity does negatively correlate with SWB and that subjective and objective insecurities are not significantly correlated. Subjective insecurity consisted of three items: perceptions of personal, political and economic insecurity. We proposed that insecurity and SWB are mediated by the level of social capital found in the region. Social capital was defined as interpersonal trust as well as the frequency of participation of producers in voluntary associations. We used a multiple and multilevel regression models to test the hypotheses. Based on a survey of 742 rural producers in five conflicted areas we tested and found that the perceptions of insecurity do correlate significantly (negatively) with levels of subjective wellbeing. We also found a significant contribution of social capital with levels of SWB. Significant correlations between demographic variables and SWB were replicated at rural areas. These results have important implications for public policy and future research.

    Trends in Supply Chain Management in the Colombian Pharmaceutical Sector
    (Universidad de los Andes, 2007) Hernández Chaustre, Sergio Alberto de Jesús; Orozco Collazos, Luz Elena
    The main hypothesis of this study is that Colombian companies in the pharmaceutical sector use at least the50% of processes in the third level of SCOR model. This hypothesis is supported in national regulation requirements for the sector, which emulate international standards. Economic and cultural environments allow a second hypothesis: companies apply less than 75%of best practices suggested by the SCOR model. Four sub-sectors were studied: veterinary, medicinal plants, medicines and vitamins. These sectors represent approximately 90% of the pharmaceutical sector, and their study represents a first approach in learning about trends in the complete sector.

    Violence, Insecurity and Hybrid Organizational Forms: A Study in Conflict-ridden zones in Colombia
    (Universidad de los Andes, 2010) Forero Pineda, Clemente; Wills Herrera, Eduardo; Andonova Zuleta, Veneta Stefanova; Orozco Collazos, Luz Elena; Pardo Aragón, Oscar Armando
    We study organizational forms in conflict-ridden zones of rural Colombia and analyze the impact of violence and subjective perceptions of insecurity on the choice of hybrid organizational modes. Based on a survey of 743 rural producers in five geographical regions, we find that the perceptions of personal and political insecurity correlate positively with hybridization in the organization of production and that the perception of personal insecurity correlates positively with the hybridization in the organization of distribution. Objective measures of violence also correlate positively with the degree of hybridization: the homicide rate is related to hybridization in distribution, and displaced population is related to hybridization in production. The distinction between the organizational forms of production and distribution appears to be important, since the determinants of hybridization substantially differ between these two activities.
