Estudio prospectivo de las condiciones del mercado laboral colombiano para los egresados de la Facultad de Administración de la Universidad del Rosario del 2017

El presente trabajo logra exponer los diferentes futuros escenarios laborales que viven los egresados de la Facultad de Administración de la Universidad del Rosario. Para esto se ha recurrido al uso de metodología la prospectiva, unidos a un sólido marco teórico, a la utilización de la herramienta Mic Mac y a la opinión de expertos en el tema. En la actualidad, la problemática que viven la mayoría de los egresados radica en la falta de experiencia a la hora de ser admitidos en un puesto laboral, lo cual se representa en el aumento del desempleo y un malestar para su vida laboral. Esta es la razón por la cual se percibió la necesidad de hacer este estudio, para esclarecer cómo es la realidad de los profesionales, y al final poder proporcionar una alternativa para la mejora de los escenarios. Sin embargo, es importante recordar que el futuro es incierto y que todos los escenarios experimentados son resultado de estudios científicos y no de realidades comprobadas.

Plataforma Tecnológica Colaborativa Comunidad de Negocios San Antonio, Chile, red de aprovisionamiento local: OpenSupply

El proyecto que se quiere plantear es la creación de una Plataforma electrónica a través de la cual se pretende agrupar a los diferentes proveedores que intervienen en la cadena de abastecimiento de la comunidad logística de San Antonio, abriendo la posibilidad de participación de empresas grandes y pequeñas y más aun promoviendo la creación de las mismas por parte de los ciudadanos de la región, de esta manera, se eliminan las brechas asimétricas existentes entre la oferta y la demanda permitiendo que las empresas medianas y grandes accedan a ofertas y transacciones con empresas proveedoras medianas y pequeñas. Dicho proyecto, tiene como objetivo general el consolidar los procesos de abastecimiento implementados por las empresas a través de la organización y estandarización de los mismos mediante el uso del portal, planteado en el presente proyecto, como apoyo tecnológico. Existen dos conceptos básicos a analizar de manera teórica dentro del proyecto, el primero de ellos es el de clúster logístico-portuario, lo cuales son reconocidos como instrumentos importantes para el progreso del desarrollo industrial, innovación, competitividad y crecimiento, tomando como ejemplos a los puertos de Valencia y Long Beach en la ciudad de Los Ángeles. El segundo concepto es el de E-Procurement, el cual se desarrolla siguiendo los pasos básicos de una cadena de abastecimiento tradicional, sin embargo, lo que genera un cambio real dentro de los procesos es el hecho que los procesos de cotización y seguimiento de proveedores se van a llevar a cabo a través de una plataforma electrónica con base a las evaluaciones que se llevan a cabo por parte de las empresas demandantes de los productos o servicios ofrecidos por las compañías proveedoras. (Renko, 2011) De la misma manera, se tomaran varios proyectos de e-procurement desarrollados a nivel mundial como base comparativa y de apoyo para el presente proyecto tales como: HYDRA: Es un sistema que tiene su soporte en la web, el cual es orientado “en el medio” lo cual lo hace un sistema con una arquitectura híbrida, que posee tanto un diseño en capas como una estructura comprensiva para desarrollar integración de negocios, colaboración y monitoreo en la gestión de la cadena de suministro (Renko, 2011) IPT: BidNet ha proporcionado servicios de oferta de información a miles de proveedores y compradores de bienes en el ámbito gubernamental por más de 25 años. (Bidnet, 2013) E-BUYPLACE: E-buyplace.com es el 1° especialista en SupplierRelationship Management que ha desarrollado un original y singular SRM 100% a través de Internet. (e-buyplace, 2013) RosettaNet: La iniciativa RosettaNet anima a optimizar los procesos de la cadena de suministro mediante el establecimiento, implementación y promoción de estándares abiertos en el mercado e-Business (AQS, Advance Quality Solutions, 2002)

Desenlace intrahospitalario temprano del trauma ocupacional agudo, atendido “Entre Semana/Fin de Semana”, en una institución hospitalaria de III nivel, Bogotá, 2007 -2010

Resumen Objetivo. El desenlace temprano del trauma ocupacional agudo (TOA) puede estar condicionado al desarrollo industrial local en relación con el momento de la semana donde se presente el evento, por lo que evaluamos las diferencias en los desenlaces clínicos tempranos de trabajadores que presentaron TOA en diferentes momentos de la semana. Metodología. Se realizó un estudio descriptivo retrospectivo utilizando una base de datos administrativa de trabajadores atendidos por TOA, entre enero/2007-diciembre/2010, en una institución hospitalaria de III nivel de Bogotá. Se comparó la distribución del TOA entre semana (ES) y en fin de semana (FdS) según variables sociodemográficas/clínicas y la mediana de estancia hospitalaria (EH), el riesgo de muerte o de un trauma específico. Resultados. Se incluyeron 65169 trabajadores, la mayoría hombres (78,4%), adultos jóvenes (83,7%), edad mediana 31 años, con razón de ingreso ES:FdS 3:1, predominantemente durante el día (81,3%). La EH mediana (horas) en FdS (0,48) fue mayor que ES (0,43) (p: 0,000) en general y al evaluar por las sub-categorías de sexo, grupo de edad, momento de ingreso, área de manejo y estado al alta. Se presentaron 35 muertes, con mayor riesgo (OR;IC95%) en el grupo 45-64 años (3,47;1,71-6,76), en los ingresados en la noche (3,27;1,64-6,40) o durante el FdS (4,57;1,25-18,4). Durante el FdS se identificó mayor riesgo de TOA con compromiso de Cabeza/Cuello, traumas múltiples y de causadas por vehículos en movimiento. Durante el FdS disminuyó la frecuencia de trabajadores atendidos por Ortopedia/Oftalmología/Cirugía General (p: < 0,05). Conclusión. Evidenciamos que los trabajadores ingresados por TOA durante el FdS presentaron mayor EH y riesgo de muerte; además se identificó una redistribución en el Servicio de atención en el FdS, con una baja frecuencia de atenciones prestadas por médicos especialistas.

Simón Rodríguez: un pensamiento americano (Dossier: Bicentenario, rastros y revelaciones de la Independencia)

El autor sostiene que Simón Rodríguez se propuso crear un pensamiento americano, que conociera y llegara a resolver los problemas de la región. Estos últimos tenían que ver con la vida social, las instituciones, las conductas e ideas, las perspectivas del pasado y del futuro. Era importante crear una conciencia del “ser social” en América por medio de la Razón, y no basarse en proyectos civilizatorios inspirados en ideas importadas y en la política del exterminio, como los de Andrés Bello y Faustino Sarmiento. Guzmán enfatiza que Rodríguez fue defensor de la república, inspirado en la Revolución francesa y en las utopías sociales europeas, que sus ideas pedagógicas planteaban una instrucción social general, basada en la Razón que proviene del estudio de las cosas, y en una valoración por el trabajo útil. El autor resalta dos nociones de Rodríguez: que sin luces, no habría proyectos propios y los políticos estarían condenados a imitar, y que la realidad podía cambiarse con la unión, el desarrollo de las industrias y el derecho de propiedad, junto a la enseñanza de oficios útiles.

Distribution of selected heavy metals in sediments of the Agueda river (Central Portugal)

The state of river water deterioration in the Agueda hydrographic basin, mostly in the western part, partly reflects the high rate of housing and industrial development in this area in recent years. The streams have acted as a sink for organic and inorganic loads from several origins: domestic and industrial sewage and agricultural waste. The contents of the heavy metals Cr, Cd, Ni, Cu, Pb, and Zn were studied by sequential chemical extraction of the principal geochemical phases of streambed sediments, in the <63 mum fraction, in order to assess their potential availability to the environment, investigating, the metal concentrations, assemblages, and trends. The granulometric and mineralogical characteristics of this sediment fraction were also studied. This study revealed clear pollution by Cr, Cd, Ni, Cu, Zn, and Pb, as a result from both natural and anthropogenic origins. The chemical transport of metals appears to be essentially by the following geochemical phases, in decreasing order of significance: (exchangeable + carbonates) much greater than (organics) much greater than (Mn and Fe oxides and hydroxides). The (exchangeable + carbonate) phase plays an important part in the fixation of Cu, Ni, Zn, and Cd. The organic phase is important in the fixation of Cr, Pb, and also Cu and Ni. Analyzing the metal contents in the residual fraction, we conclude that Zn and Cd are the most mobile, and Cr and Pb are less mobile than Cu and Ni. The proximity of the pollutant sources and the timing of the influx of contaminated material control the distribution of the contaminant-related sediments locally and on the network scale.

A project managed by a multi disciplinary practice: a systems based case study.

The technique of linear responsibility analysis is used for a retrospective case study of a private industrial development consisting of an engineering factory and offices. A multi-disciplinary professional practice was used to manage and design the project. The organizational structure adopted on the project is analysed using concepts from systems theory which are included in Walker's theoretical model of the structure of building project organizations (Walker, 1981). This model proposes that the process of buildings provision can be viewed as systems and sub-systems which are differentiated form each other at decision points. Further to this, the sub-systematic analysis of the relationship between the contributors gives a quantitative assessment of the efficiency of the organizational structure used. There was a high level of satisfaction with the completed project and this is reflected by the way in which the organization structure corresponded to the model's proposition. However, the project was subject to string environmental forces which the project organization was not capable of entirely overcoming.

Research priorities in observing and modeling urban weather and climate

In 2007, the world reached the unprecedented milestone of half of its people living in cities, and that proportion is projected to be 60% in 2030. The combined effect of global climate change and rapid urban growth, accompanied by economic and industrial development, will likely make city residents more vulnerable to a number of urban environmental problems, including extreme weather and climate conditions, sea-level rise, poor public health and air quality, atmospheric transport of accidental or intentional releases of toxic material, and limited water resources. One fundamental aspect of predicting the future risks and defining mitigation strategies is to understand the weather and regional climate affected by cities. For this reason, dozens of researchers from many disciplines and nations attended the Urban Weather and Climate Workshop.1 Twenty-five students from Chinese universities and institutes also took part. The presentations by the workshop's participants span a wide range of topics, from the interaction between the urban climate and energy consumption in climate-change environments to the impact of urban areas on storms and local circulations, and from the impact of urbanization on the hydrological cycle to air quality and weather prediction.

The impact of land-use practices on soil microbes

The extensive use of land resources for food production, fibre for construction, wood pulp for paper, removal for extractive industries, sealing for urban and industrial development and as a receiver (either deliberate or accidental) of polluting substances has wrought huge changes in the chemistry, structure and biology of soils, away from their natural state.

Envisioning Indochina : the spatial and social ordering and imagining of a French colony

The emergence of Indochina in the French imagination was articulated in both representational and institutional modes. Representation involves the transmission of colonial ideals through more obtuse means; that is, through literary texts, travelogues, exhibitions, film and advertising. However, these textual sites feed from and invest in a material situation, which was the institutional arm of colonialism. Indochina was institutionally articulated in cartographic maps and surveys, in the new social spaces of cities and towns, in architectural and technological forms, through social technologies of discipline and welfare and in cultural and religious organisations. The aim of this thesis is to analyse, across a number of textual sites, the representation and institutionalisation of Otherness through the politics of space in the French colony of Indochina, Indochine in this sense becomes a spatial discourse. The French constructed a mental and physical space for Indochina by blanketing and suffocating the original cultural landscape, which in fact had to be ignored for this process to occur. What actually became manifest as a result of this projection stemmed from the French imagination. Just as the French manipulated space, language also underwent the same process of reduction. The Vietnamese script was latinised to make it more 'useable' and ‘accessible’. Through christening the union of Indochina; initiating a comprehensive writing reform; and renaming the streets in the colonial cities, the French used language us another tool for 'making transparent'. Furthermore, the colonial powers established a communication and transport network throughout the colony in an attempt to materialise their fictive (artificial) vision of a unified French Indochinese space. The accessibility and design of these different modes of transport reflected the gendered, racial and class divisions inherent in the colonial establishment. At the heart of representing and institutionalising Indochina was the desire to control and contain. This characterised French imperial ordering of space in the city and the rural areas. In rural areas land was divided into small parcels and alienated to individuals or worked into precise grids for the rubber plantation. In urban centres the native quarter was clearly demarcated from the European quarter which functioned as its modern, progressive Other. The rationale behind this segregation was premised on European, nineteenth century discourses of race, class, gender and hygiene. Influenced by Darwinian and neo-Lamarkian theories of race, this biological discourse identified the 'working class', 'women' and 'the native' as not only biologically but also culturally inferior. They were perceived as a potential, degenerative threat to the biological, cultural and industrial development of the nation. In the colonial context, space was thus ordered and domesticated to control the native population. Coextensively, the literature which springs from such a structure will be tainted by the same ideas, and thus the spaces it formulates within the readers mind feed on and reinforce this foundation. Examples of gender and indigenous narratives which contest this imaginative, transparent topography are analysed throughout this thesis. They provide instances of struggle and resistance which undermine the ideal/stereotypical level of architectural and planned space and delineate an alternative insight into colonial spatial and social relations. The fictional accounts of European women and indigenous writers both challenge and reaffirm the fixity of some of these idealised colonial boundaries. In various literary, historical, political, architectural and cinematic discourses Indochina has been und continues to be depicted as a modern city and exotic Utopia. Informed by the mood of nostalgia, exotic images of Indochina have resurfaced in contemporary French culture. France's continued desire to create, control and maintain an Indochinese space in the French public imagination reinforces the multi-layered, interconnected and persistent nature of colonial discourse.

Aquaculture effluent : impacts and remedies for protecting the environment and human health

Knowledge in the field of environmental health is growing rapidly. Within the context of external factors that define its boundaries, environmental health has evolved over time into a complex, multidisciplinary and ill-defined field with uncertain solutions. Many of the key determinants and solutions to environmental health lie outside the direct realm of health and are strongly dependent on environmental changes, water and sanitation, industrial development, education, employment, trade, tourism, agriculture, urbanization, energy, housing and national security. Environmental risks, vulnerability and variability manifest themselves in different ways and at different time scales. While there are shared global and transnational problems, each community, country or region faces its own unique environmental health problems, the solution of which depends on circumstances surrounding the resources, customs, institutions, values and environmental vulnerability. This work will contain critical reviews and assessments of environmental health practices and research that have worked in places and thus can guide programs and economic development in other countries or regions.

Evolução setorial e trajetórias tecnológicas em nível de empresas na indústria de celulose e papel no Brasil (1970 - 2004): contexto da política de substituição de importações à competição globalizada

Accordingly, a variety of firms's technological capabilities studies, the literature recently is still lacking about the dynamic of sector evolution and technological development in inter-firm and their implication for technical and economical financial performance. More lacking is the research catching up the evolution of industrial sectors after the institutional reforms in the 90. For that, the focus of the dissertation is to analyze the main of the evolution of the pulp and paper industry from 1970 to 2004, using as reference points the import-substitution policy and the economic deregulation of the 1990s. Futhermore, the work tries to evaluate how such changes at industry level have been perceived from a firm point of view in terms of accumulation of technological capabilities and improvement of economic financial performance. This linkage is tested and examined in the following firms: Aracruz (Barra do Riacho establishment ), Klabin (Monte Alegre establishment) e Votorantim Celulose e Papel ¿ VCP (Jacareí establishment), defining the same time period of sectoral level. As far as the industry level study is concerned, it is based on the average rate of annual growth of some selected variables, given that the technological capabilities test is performed according to the methodology already existing in the literature, but properly adapted to the pulp and paper case. Similarly, the analysis regarding the improvement of the economic financial performance is based on a set of industry specific indicators. Hence, the work is built upon multiple case studies, taking into account both the qualitative and quantitative evidence, i.e. interviews, direct observations, as well as firm reports. Finally, it is worth emphasizing as the analysis of the changes in the sector, in conjunction with the above mentioned methodology used to measure the technological capabilities in the context of an evolving industrial regime, is still lacking in emerging economies as well as in Brazil. According to the empirical evidence, the reforms of the 1990s had a positive impact on the industrial development, from both the national and international viewpoint. Such a transformation was evident at firm level in terms of accumulation of technological capabilities and improvement of economic financial indicators. Indeed, the results show that the speed of accumulation of technological capabilities within the firms influences positively the performance indicators. On the other hand, these are also related to external factors, such as the macroeconomic conditions, which as such have not been considered in details.

Mensuração de Capacidade Tecnológica no Contexto de Industrialização Recente: Uma Breve Reflexão Crítica Sobre Taxonomias e Evidências de Pesquisas Recentes

This dissertation aims at examining empirical evidences obtained in the light of taxonomies and strategies for measuring firms technological capabilities and innovation in the context of developing countries, motivated by the fact that debates and studies directed to innovation has been intensified, for the last thirty years, by the recognition of its vital and growing importance to the technological, economic, competitive and industrial development of firms and countries. Two main tendencies can be identified on this debate. At one side, it¿s the literature related to the developed countries logic, whose companies are, in majority, positioned at the technological frontier, characterized by the domain of innovative advanced capabilities, directed to its sustaining, deepening and renewal. At the other side, there are the perspectives directed to the developing countries reality, where there is a prevalence of companies with deficiency of resources, still in process of accumulating basic and intermediate technological capabilities, with characteristics and technological development trajectories distinct or even reverse from those of developing countries. From this last tradition of studies, the measuring approaches based in C&T indicators and in types and levels of technological capabilities stand out. The first offers a macro level, aggregated perspective, through the analysis of a representative sample of firms, seeking to the generation of internationally comparable data, without addressing the intraorganizational specificities and nuances of the paths of technological accumulation developed by the firms, using, mostly, R&D statistics, patents, individual qualifications, indicators that carry their own limitations. On the other hand, studies that examine types and levels of technological capabilities are scarce, usually directed to a small sample of firms and/or industrial sectors. Therefore, in the light of the focus and potentialities of each of the perspectives, this scenario exposes a lack of studies that examine, in a parallel and complementary way, both types of strategies, seeking to offer more realistic, consistent and concrete information about the technological reality of developing countries. In order to close this gap, this dissertation examines (i) strategies of innovation measurement in the contexts of developing countries based on traditional approaches and C&T indicators, represented by four innovation surveys - ECIB, PINTEC, PAEP and EAI, and, (ii) from the perspective of technological capabilities as an intrinsic resource of the firm, the development of which occurs in a cumulative way and based on learning, presents and extracts generalizations of empirical applications of a metric that identifies types and levels of technological capabilities, through a dynamic and intra-firm perspective. The exam of the empirical evidences of the two approaches showed what each one of the metrics are capable to offer and the way they can contribute to the generation of information that reflect the technological development of specific industrial sectors in developing countries. In spite of the fact that the focus, objective, perspective, inclusion, scope and lens used are substantially distinct, generating, on a side, an aggregated view, and of other, an intra-sector, intra-organizational and specific view, the results suggest that the use of one doesn't implicate discarding or abdicating the other. On the contrary, using both in a complementary way means the generation of more complete, rich and relevant evidences and analysis that offer a realistic notion of the industrial development and contribute in a more direct way to the design of corporate strategies and government policies, including those directed to the macro level aspects just as those more specific and focused, designed to increment and foment firms in-house innovative efforts.

Análise do desempenho de longo prazo dos IPOs de empresas com participação prévia de fundos de private equity e venture capital de 2004 a 2011 na BM&F Bovespa

O mercado brasileiro de ofertas públicas iniciais a partir de 2004 passou por um reaquecimento. O período até 2008, segundo a Agência Brasileira de Desenvolvimento Industrial – ABDI (2009) foi marcado pela aceleração das saídas de investidores em Private Equity e Venture Capital (PE/VC) via mercado de ações. Esses fundos são bem ativos nas empresas investidas e buscam ter acesso e influenciar as decisões dos administradores, exigem um volume grande de informações gerenciais, se preocupam com a profissionalização da gestão da empresa além de impor práticas de governança e transparência. Por serem investidores ativos espera-se que as empresas que tiveram participação desses veículos de investimento no momento anterior a abertura do capital apresentem retornos melhores do que outras sem essa participação. Assim objetivo desse estudo é verificar se há evidencias de que a presença de fundos de private equitiy ou venture capital no capital social da empresa antes de seu lançamento afeta o desempenho de longo prazo de suas ações, no presente estudo estabelecido como até 3 anos. Foi utilizada a metodologia de estudo de eventos para a investigação dos retornos de uma amostra de 126 IPOs ocorridos entre 2004 e 2011 no Brasil. A metodologia empregada tem como base o trabalho de Ritter (1991) com as recomendações de Khotari e Warner (2006), Ahern (2009) e Mackinlay (1997). Para o cálculo dos retronos anormais acumulados, ou cummulative abnormal returns – CAR utilizou-se o retorno ajustado pelo mercado, ou Market Adjusted Returns Equaly Wheighted, MAREW, utilizando como benchmark o Ibovespa e tendo como base um portifólio com pesos iguais. Verificou-se que há um retorno anormal médio de 3,47% no dia do lançamento que com o passar do tempo o retorno se torna negativo, sendo -15,27% no final do primeiro ano, -37,32% no final do segundo ano e chegando a -36,20% no final do terceiro ano. Para verificar o que influencia o CAR no longo prazo, foram relizadas regressões para os períodos de 1, 6, 12, 24 e 36 com as variáveis de controle Tamanho da Empresa, Tamanho da Oferta, Proporção da Oferta Primária, Idade, Quantidade de Investidores e Underprice para medir qual a influência de um fundo de Private Equity no retorno excedente acumulado das ações. A presença de um fundo de Private Equity ou Venture Capital se mostrou significativa apenas depois de seis meses do lançamento.
