    We have witnessed a fast growth in academic interest on entrepreneurship over the past two to three decades, although at disparate paces in different countries. A wealth of papers presented and published, books, dedicated journals, websites, professional and research groups have emerged accompanying this increased interest. It is thus important to understand what are these scholars studying. In this paper we examine the state of the art in entrepreneurship research in Brazil, by scrutinizing the entire track record of the papers presented at the EnANPAD over a twelve years period: 1997 -to 2008. The results of the bibliometric analysis revealed that entrepreneurship research maintains a broad spectrum of interests, focusing both on contextual, individual and process issues. Less visible is a unified theoretical background or the use of established theories foundational to other management disciplines. It is notable the increase in Brazilian entrepreneurship research, both empiric, theoretical and case-study based. We conclude with an umbrella discussion and suggestions for future research.entrepreneurship research, entrepreneur, bibliometric study, EnANPAD

    Mergers and acquisitions (M&As) are important modes through which firms undertake their domestic and international strategies. This bibliometric review examines the extant research on M&As in the top five strategic management journals during a ten years period ? from 2000 to 2009. The 90 articles identified in these top journals denote an eclectic theoretical focus with the prevalence of four theories ? resource-based view, transaction costs, agency theory and institutional theory. We present a brief analysis of the key issues in M&A research, as well as the samples and theories more commonly used. We conclude by presenting a broad discussion comprising the methods used, the research questions investigated, the type of articles, as well as limitations and avenues for future enquiry.mergers & acquisitions; strategic management journals, bibliometric study

    Coarse aggregate is widely used in the unbound granular layers (UGM) of roads, in particular as granular sub-base and base. However, although various studies have been conducted on these materials, their mechanical behaviour still has not been properly characterized, in Portuguese conditions, especially due to reasons connected to the heterogeneity of the rock masses from which they come from. This has special importance for Portuguese pavement technology. In the attempt of contributing for a better knowledge of that behaviour, a work was developed having the aim of obtain the mechanical characterization and the establishment of behaviour models for crushed materials coming from different lithologies, namely limestone and granite, susceptible of being used as UGM. This paper describes the principal results obtained from the work and pointing out the main directives that can be extracted from it, in terms of the global behaviour of a road pavement

    Trabalho apresentado sob a forma de poster no evento: IV Mediterranean Academy of Forensic Sciences Meeting, em Belek, Antalya, TurkyeIntroduction Sexual assault crimes are ubiquitous; usually unwitnessed, so victim’s statements may be the only direct evidence that it has occurred. Medical examination and biological samples collection are of inequivocal importance. Presence of spermatozoa in smears, elevated acid phosphatase and the presence of Y-STR profiler in the victim’s evidence’s, could be crucial to corroborate victim’s testimony. The Y chromosome is far the most important scientific evidence, not only due to it’s gender specificity and easy amplification in a male/female mixtures, but also because it can easily contribute for the number of unrelated male contributor’s estimation in an biological evidence. The aim of this study is to ascertain a few characteristics concerning sexual harassment and a Y-haplotype profile obtention, which may help to prove or disprove a link between individuals and objects or places. Methodology Biological samples from 782 sexual assault cases were studied. Glass slide vaginal and anal smears were stained with Papanicolau’s and Harris Hematoxilin Solution. For the phosphatase test, a commercially available test paper strip was used (Phosphatesmo KM). DNA was extracted by phenol chloroform method and PCR amplification was performed with Powerplex® Y (Promega) or AmpF1STR Y-Filer (Applied Biosystems). Fragment analysis was done by capillary electrophoresis in an ABI 3130xl. Laboratory results were compared with other data such as, victim age, alleged assailant number, time between the act and collection of biological samples. Significant variables were entered in a logistic regression model using SPSS 17.0 for data analysis. Results and conclusion Descriptive analysis reveals that victim’s age varies between 1 to 90 years old, but almost 20% were under 12 years old. Almost 87% of cases had one perpetrator. Only 10% of the victim’s declared that they had consent sexual intercourse, in the previous 48 hours and 32% take a bath before the exam. Another variable studied was the mean time of 15 hours between the act and biological sample collection. Logistic regression demonstrates that the last two variables are of considerable importance in Y-profile obtention. Concerning acid phosphatase results a male genetic identification was obtained in 12,5 % of the negative cases. In conclusion, Y-STRs study, due to their sensitivity and specificity, should be used in every sexual assault cases, contributing to the final identification of perpetrator’s, and corroborating the victim’s story.info:eu-repo/semantics/draf

    Um estudo bibliométrico dos modelos culturais na pesquisa em negócios internacionais

    Culture and the influence of national cultures and cultural differences have been widely studied in International Business (IB) research especially over the past three decades. To better understand what culture actually means and its implications on firms’ international operations, several cultural models and taxonomies have been put forward. In this paper we review the main cultural models in the extant IB research – Hofstede’s (1980), Hall’s (1976) and Troompenaars’ (1993) – and Kogut and Singh’s (1988) concept of cultural distance. In a bibliometric study of over 3,600 articles published in seven top ranked journals for IB research, we examine citations and co-citations to assess the relative use of the cultural models and the ties binding authors and theories studied. This study offers a wealth of information on the current state of IB-related research using culture that may be used to better understand the intellectual structure of the sub-field of cultural issues in IB studies but also to identify gaps for future inquiry. The results help setting a profile of the network of knowledge and permit us to conclude that Hofstede’s (1980) taxonomy on cultural characteristics is the most cited cultural taxonomy and holds ties to many of the core streams of IB-related research. In fact, despite the well-known criticisms, there is an increasing use of Hofstede’s dimensions.Key words: Cultural models, Hofstede, Trompenaars, Hall, review, bibliometric study.A cultura e a influência das culturas nacionais e das diferenças culturais têm sido amplamente estudadas em Negócios Internacionais (NI), particularmente ao longo das últimas três décadas. Para compreender melhor o que cultura realmente significa e quais as implicações nas operações internacionais das empresas, vários modelos e taxonomias têm sido apresentados. Neste artigo revemos três principais modelos culturais na pesquisa em NI – Hofstede (1980), Hall (1976) e Troompenaars (1993) – e o conceito de distância cultural de Kogut e Singh (1988). Num estudo bibliométrico de mais de 3.600 artigos publicados em sete periódicos altamente conceituados para pesquisa em NI, examinamos citações e co-citações para aferir o uso relativo dos modelos culturais e os laços interligando autores e teorias. Este estudo oferece uma colectânea de informações sobre o estado atual da pesquisa em NI que se debruça sobre cultura, que podem ser usadas para melhor compreender a estrutura intelectual do tópico de assuntos culturais em estudos de NI, mas também para identificar lacunas para futura investigação. Os resultados ajudam a traçar o perfil da rede de conhecimento e permite-nos concluir que a taxonomia das características culturais de Hofstede (1980) é a taxonomia cultural mais citada e está interligada com muitos dos ramos fundamentais da pesquisa em NI. Adicionalmente, apesar das bem conhecidas críticas, existe um uso crescente das dimensões de Hofstede.Palavras-chave: Modelos culturais, Hofstede, Trompenaars, Hall, revisão, estudo bibliométrico

    O IMPACTO SOCIAL DA UNIVERSIDADE A PARTIR DE UMA PROPOSTA DE INTERVENÇÃO

    Partimos do pressuposto que as Instituições de Ensino Superior (IES) possuem uma responsabilidade social de fomentar ações que aproximem o que é produzido na universidade. Neste sentido durante o período de 2012/2013 buscando qualificar a formação e propor novas metodologias para as aulas de Educação Física, foi desenvolvido um trabalho junto aos professores da rede municipal de Bagé/RS, que teve como característica a pesquisa de intervenção. Foram três meses de discussões, diagnósticos, reflexões e principalmente um estudo dentro do método da pesquisa-ação. Toda a pesquisa foi orientada e conduzida seguindo os ciclos da pesquisa-ação defendidos por Tripp (2005). Os resultados foram obtidos através da realização de oficinas com filmagens, fotos, registros das anotações do trabalho de campo, onde constatamos o envolvimento e adesão dos professores durante a pesquisa, favorecendo a nossa análise de percepção quanto ao desenvolvimento dos mesmos durante todo o processo. É possível afirmar que o processo da pesquisa-ação, sob a forma de intervenção, cumpriu seu papel contemplando a efetivação de dois aspectos: o primeiro no que se refere à possibilidade de intervir positivamente na realidade do professor de Educação Física da escola e o segundo de favorecer o retorno social da pesquisa
