Cuesta Arriba. Antecedentes epistemológicos y metodológicos para una Evaluación Ambiental Estratégica -EAE- en la ejecución de Políticas Planes y Programas ambientales en el Area del Gran Catamarca -AGC-

En esta comunicación se informa sobre estudios socio ambientales realizados desde las perspectivas epistemológica y metodológica, en el Area del Gran Catamarca. El propósito es contribuir a una Evaluación Estratégica Ambiental. Se examinan antecedentes y se identifica la percepción de la problemática ambiental en diferentes sectores de población.. Para la construcción del Marco teórico se analizaron información escrita (libros, revistas periódicos) y webgrafia e infografia, de origen local, nacional e internacional. El abordaje transversal de la investigación revela la complejidad epistemológica del objeto de estudio cuando se busca alcanzar una visión contemporánea, global y contextualizadora del problema. Complejidad que se evidencia en los resultados de los análisis, de contenidos, multicriterial y hermeneutico. Las indagaciones sobre percepción de la problemática ambiental recogieron testimonios orales, cuestionarios y encuestas cuyas características se describen en el trabajo. Integrantes y alumnos de la cátedra Introducción a la Investigación (Filosofía y Ciencias de la Educación), realizaron actividades de educación ambiental y prácticas solidarias desde 1999 a 2002, como forma de extensión, transferencia e inserción social de la Universidad. La metodología de investigación-acción participativa optimizó resultados. Otra fuente de datos fueron entrevistas radiales (2001-2003), durante la emisión del Programa del LIPA- Hombre y Ambiente, emitido por Radio Universidad. En la Conclusión estimamos que los antecedentes de EAE revelan que conviene aplicarla en nuestro medio y que la percepción de los problemas de mayor impacto o riesgo ambiental en pobladores del AGC evidencia conocimiento, pero falta mayor compromiso para asumir la propia responsabilidad. Enunciamos fortalezas, debilidades y recomendaciones es por tales antecedentes que las tareas de transferencia y aplicaciones hace "Cuesta Arriba" por lo dificultosa, ya que deben remontarse una serie de inconvenientes algunos de los cuales se han enunciado en la presente comunicación

Fatores críticos de sucesso como antecedentes da aceitação de um sistema de informação em uma universidade federal

In recent decades the public sector comes under pressure in order to improve its performance. The use of Information Technology (IT) has been a tool increasingly used in reaching that goal. Thus, it has become an important issue in public organizations, particularly in institutions of higher education, determine which factors influence the acceptance and use of technology, impacting on the success of its implementation and the desired organizational results. The Technology Acceptance Model - TAM was used as the basis for this study and is based on the constructs perceived usefulness and perceived ease of use. However, when it comes to integrated management systems due to the complexity of its implementation,organizational factors were added to thus seek further explanation of the acceptance of such systems. Thus, added to the model five TAM constructs related to critical success factors in implementing ERP systems, they are: support of top management, communication, training, cooperation, and technological complexity (BUENO and SALMERON, 2008). Based on the foregoing, launches the following research problem: What factors influence the acceptance and use of SIE / module academic at the Federal University of Para, from the users' perception of teachers and technicians? The purpose of this study was to identify the influence of organizational factors, and behavioral antecedents of behavioral intention to use the SIE / module academic UFPA in the perspective of teachers and technical users. This is applied research, exploratory and descriptive, quantitative with the implementation of a survey, and data collection occurred through a structured questionnaire applied to a sample of 229 teachers and 30 technical and administrative staff. Data analysis was carried out through descriptive statistics and structural equation modeling with the technique of partial least squares (PLS). Effected primarily to assess the measurement model, which were verified reliability, convergent and discriminant validity for all indicators and constructs. Then the structural model was analyzed using the bootstrap resampling technique like. In assessing statistical significance, all hypotheses were supported. The coefficient of determination (R ²) was high or average in five of the six endogenous variables, so the model explains 47.3% of the variation in behavioral intention. It is noteworthy that among the antecedents of behavioral intention (BI) analyzed in this study, perceived usefulness is the variable that has a greater effect on behavioral intention, followed by ease of use (PEU) and attitude (AT). Among the organizational aspects (critical success factors) studied technological complexity (TC) and training (ERT) were those with greatest effect on behavioral intention to use, although these effects were lower than those produced by behavioral factors (originating from TAM). It is pointed out further that the support of senior management (TMS) showed, among all variables, the least effect on the intention to use (BI) and was followed by communications (COM) and cooperation (CO), which exert a low effect on behavioral intention (BI). Therefore, as other studies on the TAM constructs were adequate for the present research. Thus, the study contributed towards proving evidence that the Technology Acceptance Model can be applied to predict the acceptance of integrated management systems, even in public.

Antecedentes de empresas portuguesas para uma internacionalização gradual de sucesso

O presente trabalho relata e analisa o processo de internacionalização tendo em atenção os antecedentes que conduziram ao sucesso das empresas analisadas. O método utilizado foi a pesquisa qualitativa, e envolveu sete entrevistas individuais realizadas numa pequena e média empresa (PME), a Valart (cinco entrevistas), e duas multinacionais, a Bosch e a Quimialmel (um quadro superior entrevistado em cada uma). Os resultados obtidos foram discutidos à luz da literatura, após a transcrição das entrevistas e codificação dos dados primários recolhidos. Pretendeu-se entender como é que as grandes multinacionais Bosch e Quimialmel alcançaram o seu sucesso a nível internacional, assim como analisar, também, como a Valart cresceu e expandiu-se ao longo do tempo. Foi então realizada uma revisão da literatura em que foram abordados temas como a internacionalização, a globalização, o marketing e a inovação, conceitos relevantes ao desenvolvimento deste estudo, revisão essa completada após o trabalho de campo, seguindo-se o grounded theory. No conteúdo do trabalho também são relatadas as atividades desenvolvidas durante o estágio na Valart, e é feita uma análise da empresa e do produto principal em questão (porta-contentores marítimos ou sideloaders). Assim, com a revisão da literatura e análise dos resultados obtidos foi possível retirar conclusões e tecer recomendações de ação / gestão na Valart, tais como investir em colaboradores especializados, abrir um departamento de marketing interligado com o comercial, e sempre apoiado em ferramentas informáticas que poderão fomentar a inovação. Os antecedentes que guiam as empresas analisadas a uma internacionalização de sucesso, internacionalização essa que tem sido gradual e por fases, nas empresas abordadas, incluem: rede de contactos internacional, competência da força de vendas, investigação e desenvolvimento (I&D) que leva a produtos diferenciados, parcerias com universidades, orientação para o cliente, existência de uma marca forte, estrutura de custos eficiente, e aproveitamento do capital humano interno. Por fim, é relevante referir que a crise interna em Portugal tem sido um fator incentivador da procura de diversificação de mercados a nível internacional. Como resultado deste estudo foi apresentado um artigo na conferência internacional ICERI 2014 (Au-Yong-Oliveira e Coelho, 2014).

Escherichia coli productor de toxina Shiga en alimentos : antecedentes y situación actual de la legislación alimentaria en Argentina

Escherichia coli productor de toxina Shiga (STEC) es un grupo bacteriano asociado a enfermedades transmitidas por alimentos. Algunos serotipos de STEC representan un grave problema para la Salud Pública, causando diarrea, colitis hemorrágica y síndrome urémico hemolítico (SUH). En Argentina el SUH es endémico y constituye la primera causa de insuficiencia renal aguda en niños menores de 5 años. Los recientes brotes en el mundo de enfermedades causadas por E. coli no-O157, han resultado fuertemente impactantes no solo a nivel de la salud pública sino también a nivel comercial. Estos eventos han puesto en evidencia la necesidad de contar con un nuevo marco legislativo en materia alimentaria. En Argentina la reciente aprobación por parte dela Comisión Nacional de Alimentos (CONAL) respecto de la incorporación al Código Alimentario Argentino (CAA) de criterios microbiológicos que incluyen la ausencia de STEC no-O157 favorece la prevención de aquellos serogrupos prevalentes en el país. Estos criterios microbiológicos fueron establecidos para carne picada fresca, alimentos listos para consumir, chacinados, frutas, verduras y hortalizas mínimamente procesadas. Es fundamental destacar que los serogrupos (O145, O121, O26, O111 y O103) propuestos para la modificación del CAA son aquellos que exige la normativa actual de Estados Unidos, y los que indica la Norma ISO 13136, hoy por hoy, la utilizada en la Unión Europea (UE) como referencia en el tema. Esto conlleva beneficios futuros, ya que, al homologar las mismas exigencias técnicas microbiológicas se facilitara el intercambio de alimentos entre países. Teniendo en cuenta que la falta de criterios uniformes regulatorios a nivel internacional, generan discrepancias que traen aparejados, obstáculos técnicos al comercio (OTC), pudiendo llegar a ser barreras paraarancelarias encubiertas, con consiguientes perjuicios económicos que pueden ser transferidos a las naciones exportadoras de alimento.

Estudo empírico de antecedentes do sucesso de sistemas de informação: análise de um sistema de apoio à decisão em uma universidade pública

Universities are institutions that generate and manipulate large amounts of data as a result of the multiple functions they perform, of the amount of involved professionals and students they attend. Information gathered from these data is used, for example, for operational activities and to support decision-making by managers. To assist managers in accomplishing their tasks, the Information Systems (IS) are presented as tools that offer features aiming to improve the performance of its users, assist with routine tasks and provide support to decision-making. The purpose of this research is to evaluate the influence of the users features and of the task in the success of IS. The study is of a descriptive-exploratory nature, therefore, the constructs used to define the conceptual model of the research are known and previously validated. However, individual features of users and of the task are IS success antecedents. In order to test the influence of these antecedents, it was developed a decision support IS that uses the Multicriteria Decision Aid Constructivist (MCDA-C) methodology with the participation and involvement of users. The sample consisted of managers and former managers of UTFPR Campus Pato Branco who work or have worked in teaching activities, research, extension and management. For data collection an experiment was conducted in the computer lab of the Campus Pato Branco in order to verify the hypotheses of the research. The experiment consisted of performing a distribution task of teaching positions between the academic departments using the IS developed. The task involved decision-making related to management activities. The data that fed the system used were real, from the Campus itself. A questionnaire was answered by the participants of the experiment in order to obtain data to verify the research hypotheses. The results obtained from the data analysis partially confirmed the influence of the individual features in IS success and fully confirmed the influence of task features. The data collected failed to support significant ratio between the individual features and the individual impact. For many of the participants the first contact with the IS was during the experiment, which indicates the lack of experience with the system. Regarding the success of IS, the data revealed that there is no significance in the relationship between Information Quality (IQ) and Individual Impact (II). It is noteworthy that the IS used in the experiment is to support decision-making and the information provided by this system are strictly quantitative, which may have caused some conflict in the analysis of the criteria involved in the decision-making process. This is because the criteria of teaching, research, extension and management are interconnected such that one reflects on another. Thus, the opinion of the managers does not depend exclusively on quantitative data, but also of knowledge and value judgment that each manager has about the problem to be solved.

Análise dos antecedentes das intenções empreendedoras nos estudantes de Reabilitação Psicomotora : estudo com alunos dos primeiro e segundo ciclos do ensino superior

Este estudo pretende (1) analisar os antecedentes das Intenções Empreendedoras (IE) dos estudantes de Reabilitação Psicomotora da Faculdade de Motricidade Humana de ambos os ciclos de ensino e (2) as Intenções Empreendedoras dos estudantes em função das suas características sociodemográficas. A amostra compreendeu um total de 130 alunos, aos quais foi aplicado uma versão adaptada do Questionário das Intenções Empreendedoras (EIQ: Liñán & Chen, 2009) que se baseia na Teoria do Comportamento Planeado (TCP: Ajzen, 1991) e inclui os seguintes fatores: Intenções Empreendedoras (IE), Atitude Percebida (AP), Controlo Comportamental Percebido (CCP) e Normas Subjetivas (NS). Foram realizados testes de regressão linear para identificar quais os fatores da TCP que influenciam as IE. Posteriormente, foram conduzidos testes t-student para comparar os valores médios dos quatro fatores da TCP em função do género, conhecimento de Empreendedores, pática desportiva, experiência profissional, participação na Associação de Estudantes e ciclo de ensino. Os resultados permitiram constatar que os antecedentes mais significativos das IE são a AP e o CCP e que existem maiores IE nos alunos que têm experiência profissional, que praticam/praticaram desporto e nos que conhecem um empreendedor. Estes resultados sugerem que, influenciando alguns destes aspetos, é possível aumentar as Intenções Empreendedoras dos estudantes.
