Desindustrialização no Brasil Sintomas e causas / Desindustrializarion in Brazil: symptoms and causes

Ana Carolina Sartori Natal 25 September 2012 (has links)
Este trabalho pretende contribuir para o entendimento sobre a desindustrialização brasileira, bem como propor uma reflexão sobre o futuro das políticas de governo atualmente vigentes. Para isso, procurou-se inicialmente avaliar a literatura nacional e estrangeira sobre o tema da desindustrialização. O objetivo é, portanto, observar através dos dados e indicadores mais recomendados pela literatura existente, se o Brasil apresenta, realmente, sinais de que está passando por um processo de desindustrialização. Os agregados econômicos analisados foram: emprego, produto e o setor externo. As respectivas séries revelaram, em seu conjunto, que o Brasil está enfrentando, desde meados dos anos 1980, o fenômeno da desindustrialização. As principais causas que contribuem para explicar o porquê desse processo são: o avanço das commodities na pauta exportadora brasileira, a recente valorização da moeda nacional, a baixa densidade tecnológica dos produtos industriais brasileiros, as mudanças de políticas econômicas dos anos 1980 e 1990 e, finalmente, o processo geral recente do capitalismo, no contexto de um mundo globalizado. / This work aims to contribute for the understanding of the Brazilian deindustrialization and to do an assessment on the future of government policies currently in force. For this purpose, we sought to evaluate the domestic and international literature on deindustrialization. The goal is to observe through the data and indicators most recommended by leading authors, if Brazil has indeed signs that is undergoing a process of deindustrialization. The economic aggregates that are analyzed, including the following variables: employment, output and the external sector. The respective series show, on the whole, that Brazil is indeed experiencing, since the mid 1980s, the phenomenon of deindustrialization. The main causes contributing to explain why this process is in process: the advancement of "commodities" in Brazilian exports, the recent appreciation of the domestic currency, the low technological density of Brazilian industrial products, changes in economic policies of the 1980s and 1990s, and finally the general and recent evolution of capitalism.

A Neurociências no Brasil de 2006 a 2013, indexada na Web of Science : produção científica, colaboração e impacto

Hoppen, Natascha Helena Franz January 2014 (has links)
Esta pesquisa trata de um estudo exploratório sobre a produção científica brasileira em Neurociências, com base nos artigos indexados na Web of Science no período de 2006 a 2013. Utiliza indicadores bibliométricos de produção, colaboração, impacto e de associação temática e os softwares BibExcel, Excel, Philcarto, SPSS e VOSviewer para visualizar características da área. No referencial teórico são apresentadas breves contextualizações sobre comunicação científica e indicadores bibliométricos, histórico da ciência e da Neurociências no Brasil, além de análises bibliométricas da área realizadas em outros países. A ausência de estudos com enfoque bibliométrico sobre a Neurociências brasileira se coloca como uma das justificativas da pesquisa. O corpus principal do estudo é composto por 9655 artigos e 57932 trabalhos constituem o corpus de documentos citantes. Constata crescimento linear da produção brasileira no período da pesquisa, com índice de crescimento maior do que a produção científica mundial da área; porcentagem de artigos publicados em inglês, em geral, maior do que para outras áreas de pesquisa, e preferência dos neurocientistas brasileiros por publicar seus trabalhos em periódicos estrangeiros em contrapartida à existência de publicações em português e em periódicos nacionais ligados a um único foco de pesquisa – a Psiquiatria. Psiquiatria, junto com Neurociências e Neurologia Clínica são as disciplinas de pesquisa com maior frequência na pesquisa brasileira de Neurociências, seguidas pela Farmacologia & Farmácia, Cirurgia, Bioquímica & Biologia Molecular e Ciências do Comportamento. A Ciências do Comportamento, presente na definição de autores brasileiros sobre a área, demonstra possuir significativa relevância no escopo nacional (maior do que a indicada em outros países) e se diferencia das demais ciências em seus modos de produção de artigos. Já as áreas comumente voltadas ao estudo de doenças degenerativas (Genética & Hereditariedade, Oncologia, Enfermagem, Abuso de Substâncias, Bioquímica & Biologia Molecular, Psicologia e Farmacologia & Farmácia) possuem similaridade quanto à frequência de produção e impacto, quando voltadas às pesquisas em Neurociências. A pesquisa em Neurociências se mostra transdisciplinar, visto que abrange estudos publicados em 71 áreas distintas, segundo classificação dos periódicos na Web of Science. Os modos de produção da área também se mostram transdisciplinares quando analisados no escopo dos temas de pesquisa, que se bifurcam em temas ligados à pesquisa básica e experimental e à pesquisa clínica. Além disso, a produção científica brasileira em Neurociências se mostra bastante concentrada em um número reduzido de autores, regiões do país e, principalmente, instituições, sendo a maior parte advinda de universidades públicas do país, de estados do sudeste e sul, porém com maior participação do setor privado do que a observada em outras áreas do conhecimento (principalmente universidades e hospitais privados). A colaboração ocorre em 98,57% da produção científica brasileira de Neurociências, sendo 60,79% colaboração interinstitucional e 29,4%, internacional. Os principais parceiros do Brasil na colaboração internacional são EUA, Colômbia, Argentina e Reino Unido, e as citações são recebidas de autores vinculados a instituições de todos os continentes do globo. / The research is an exploratory study on the Brazilian scientific production in Neurosciences, based on the indexed articles in Web of Science from 2006 to 2013. It uses bibliometric indicators of production, collaboration, impact and thematic association and makes use of software such as BibExcel, Excel, Philcarto, SPSS and VOSviewer to display characteristics of the area. The theoretical framework presents brief contextualization of scientific communication and bibliometric indicators, history of science and Neuroscience in Brazil, also including bibliometric analyzes of the area conducted in other countries. The absence of bibliometric focused studies on the Brazilian Neuroscience stands as one of the justifications of this research. The main corpus of the study is constituted by 9655 articles and 57 932 papers constitute the corpus of citing documents. The research observed a linear growth of Brazilian production during the period of the survey, with an index of growth greater than the global scientific production in the area; it was also shown that the percentage of articles published in English, in general, is higher than for other areas of research; and that there is a preference of Brazilian neuroscientists to publish their work in international journals in contrast with the existence of publications in Portuguese and in national periodicals related to a single focus of research - Psychiatry. Psychiatry and Neuroscience, along with Clinical Neurology, are the research disciplines with higher frequency on Brazilian Neuroscience research, followed by Pharmacology & Pharmacy, Surgery, Biochemistry & Molecular Biology and Behavioral Sciences. The Behavioral Sciences, present in the definition of Brazilian authors on the area, seem to have significant relevance in the national scope (greater relevance than the indicated in other countries) and differs from the other sciences in their modes of production of articles. The areas commonly geared to the study of degenerative diseases (Genetics & Heredity, Oncology, Nursing, Substance Abuse, Biochemistry & Molecular Biology, Psychology and Pharmacology & Pharmacy) are similar in their frequency of production and impact when directed to researches in Neuroscience. Research in neuroscience shows to be a transdisciplinary endeavor, as it covers studies published in 71 different areas according to the classification of journals on Web of Science. The modes of production in the area also show transdisciplinarity when analyzed in the scope of research topics, which bisect into topics related to basic and experimental research and clinical research. In addition, the Brazilian scientific production in Neuroscience proves to be quite concentrated in a small number of authors, regions of the country and, specially, in institutions, most of which arising from public universities in the south and southeastern states of the country, but with greater participation of the private sector than observed in other areas of knowledge (mainly universities and private hospitals). Collaboration occurs in 98.57% of the Brazilian scientific production in Neurosciences, inter-institutional collaboration occurs in 60.79% of the papers and international collaboration occurs in 29.4%. The main partners of Brazil in international collaboration are USA, Colombia, Argentina and the United Kingdom, and the quotations are received from authors linked to institutions worldwide.

Martins, Luiz Claudio, 1964- 07 July 2006 (has links)
Orientador: Heitor Moreno Junior / Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Ciencias Medicas / Made available in DSpace on 2018-08-08T07:56:02Z (GMT). No. of bitstreams: 1 Martins_LuizClaudio_M.pdf: 906458 bytes, checksum: 5eca8eb707e90d3712220013fdc6e1f3 (MD5) Previous issue date: 2006 / Resumo: A vasopressina é um nonapeptídeo que possui moléculas de cisteína na posição um e seis ligadas por uma ponte dissulfeto, sendo sintetizada nos neurônios localizados nos núcleos supraópticos e paraventriculares do hipotálamo e transportada para a hipófise posterior onde é armazenada em forma de grânulos. A vasopressina tem seu efeito vasopressor conhecido deste o final do século XIX. Sua secreção é complexa, sendo liberada em situações de choque, hemorragias, síncope vagal, entre outras. Possui três tipos de receptores (V1, V2 e V3), sendo que o receptor V1 fica localizado nos vasos sanguíneos e é responsável pelo efeito vasoconstritor. Mais recentemente, o uso da vasopressina como medicação coadjuvante às catecolaminas no tratamento do choque vasodilatatório vem sendo descrito. A vasopressina normaliza a pressão arterial possibilitando que as doses de catecolaminas sejam diminuídas. É descrito que o uso da vasopressina em situações de choque é também associado a efeitos colaterais, como isquemia de mucosas, pele e miocárdica. O uso clínico rotineiro da vasopressina é muito limitado, sendo pouco conhecidas as doses que devem ser usadas para melhorar a hemodinâmica sem prejudicar a oferta tecidual de oxigênio. Neste estudo foi investigado os efeitos hemodinâmicos da vasopressina, em doses progressivas em cães anestesiados. Dezesseis cães sem raça definida, foram anestesiados e distribuídos aleatoriamente em dois grupos: Controle e Vasopressina. O grupo Vasopressina recebeu vasopressina nas doses 0,01 ; 0,1 e 1,0 U/kg/min por 10 minutos. Após a infusão foi realizado estudo hemodinâmico. Nas doses de 0,1 e 1,0 U/kg/min observou-se diminuição do índice cardíaco e da freqüência cardíaca, aumento da pressão arterial média e do índice de resistência vascular sistêmica. Na dose de 1,0 U/kg/min observou-se aumento do índice da resistência vascular pulmonar. Os resultados nos permitem concluir que a vasopressina pode ser útil nomanuseio do choque vasoplégico. Porém, a possibilidade de ocorrência de efeitos cronotrópicos e inotrópicos negativos podem deteriorar o estado metabólico no choque / Abstract: Introduction: Vasopressin is a neuropeptide with potent vasoconstrictor effect, but clinical experience with vasopressin in continuous infusion has been limited. In this study, we investigated the effects of vasopressin in continuous infusion on hemodynamic parameters in anesthetized dogs. Material and Methods: Mongrel dogs (n = 16) anesthetized and randomized in two groups: control and vasopressin. The vasopressin group received the following doses: 0.01 U/kg/min, 0.1 U/kg/min and 1.0 U/kg/min during 10 min. After infusion invasive hemodynamic study was performed. Results: Vasopressin continuous infusion in doses of 0.1 and 1.0 U/Kg/min for 10 minutes induced a significant decrease of heart rate and cardiac index, and significant increase of mean arterial pressure and systemic vascular resistance index. The 1.0 U/kg/min dose also induced a significant increase of pulmonary vascular resistance index. Conclusion: Increase of MAP and SVRI suggest vassopressin might be useful in managing a state of vasoplegic shock, however negative inotropic and chronotropic effects will also occur, what may deteriorate the metabolic state in a vasoplegic shock. Clinical experience utilizing vasopressin in vasoplegic shock is limited, as well as which dose should be used to minimize its deleterious effects / Mestrado / Mestre em Farmacologia

Análise estrutural do emprego formal e informal na economia brasileira / Structural analysis of the formal and informal jobs in the Brazilian economy

Fernanda Sartori de Camargo 07 August 2006 (has links)
A reorganização econômica, caracterizada pelo processo de globalização, provocou alterações nas estruturas produtivas da economia brasileira e, conseqüentemente, mudanças no mercado de trabalho. Essas mudanças refletiram-se nas características setoriais de emprego, trazendo uma grande preocupação quanto às relações de trabalho e à crescente taxa de desemprego. A reorientação do modelo de desenvolvimento, que transitava de proteção ao setor industrial para uma economia aberta e a consolidação da moeda, a partir de 1990, originou profundas mudanças no mercado de trabalho brasileiro. Os postos de trabalho dos setores primário e secundário foram reduzidos, enquanto que, no setor terciário, houve aumento dos empregos, mas não suficiente para absorver todos os trabalhadores liberados dos demais setores. A participação dos trabalhadores no mercado informal no ano de 2003 representava cerca de 52%. Dessa forma, a questão de empregos no Brasil nos últimos anos tem se tornado cada vez mais discutida e questionada quanto à capacidade de gerar novos empregos e qual a qualidade desses empregos. O trabalho pretende discutir as características e evolução do pessoal ocupado procurando analisar a relação setorial entre os empregos formais e informais, a partir de 1990, sob a ótica do modelo Insumo-Produto. Os principais resultados apontam que houve uma redução da capacidade de gerar empregos para cada um milhão de reais da produção. Os dados mostram que apesar da proporção de trabalhadores informais na economia ser superior aos trabalhadores na formalidade, o setor formal foi o responsável por cerca de 60% dos empregos gerados no período estudado. / The reorganization of the Brazilian economy, in the globalization process, has brought out changes in its productive structure, and, consequently, changes in the job market. These changes had impact on the employment at the sectoral level, with great concerns related to the labor relations and to the growing unemployment rates. In the 1990s, the change in the focus of the development strategy, from a closed protected economy to an open economy with monetary control, has originated deep changes in the labor market. The number of employed persons in the primary and secondary sector was reduced, while in the tertiary sector there was an increase in the number of jobs, but not enough to absorb all the employees released from the previous two sectors. The share of informal jobs in the Brazilian economy was around 52% in 2003. In this way, the question of employment generated by the economic sectors, in number and quality, has become a crucial issue. The goal of this work is to study the characteristics and the evolution of the occupied persons, and to relate it with the formal and informal job market, as well as the economy productive structure, using for that input-output matrices constructed for the Brazilian economy. The main results show that there was a reduction in the capacity of the economy to generate employment for every million of Reais produced in a given sector. The data also shows that despite the ratio of informal workers in the economy being superior to the workers in the formality, the formal sector was responsible for about 60% of the jobs generated in the period of analysis.

Além disso, analisar possíveis correlações entre os valores de capacidades aeróbias e anaeróbias obtidos no teste convencional de Potência Crítica e all-out de três minutos realizados em esteira rolante não motorizada, e teste de Lactato mínimo realizado na esteira rolante motorizada. Para isto, dez indivíduos do sexo masculino, com a faixa etária média de 23 ± 4 anos compareceram ao laboratório nove vezes, para a coleta dos dados. Nas duas primeiras, foram concretizadas a avaliação antropométrica e a adaptação ao ergômetro. Após essa adaptação, foram utilizadas quatro visitas para aplicação do protocolo convencional de determinação da potência crítica. Para realização do teste e reteste de all-out de três minutos (AO3) foram utilizadas mais duas visitas, seguidas de mais uma para aplicação do teste de Lactato mínimo. É importante ressaltar que foi respeitado um intervalo de no mínimo 24 horas entre todos os testes para recuperação muscular dos avaliados. Além disso, com a escessão da adaptação aos ergômetros e antropometria. Os dados coletados foram posteriormente inseridos em pacote estatístico Statistica 6.0 (Statsoft, EUA), SPSS 16.0 para Windows (SPSS Inc., EUA) , verificada a normalidade da distribuição pelo teste de Shapiro-Wilk e a homogeneidade pelo de Levene, para decisão de uso de estatística paramétrica (Anova One-way e Two-way e quando necessário post-hoc Newmann Keuls, para comparação das variáveis. Teste t de Student e teste de correlação de Pearson e intra classe (ICC) de concordância absoluta também foram aplicados. Para todas as análises foi adotado nível de significância de p ? 0,05. Os principais achados da presente pesquisa sugerem que AO3 em corrida atada na ENM é uma metodologia reprodutível. Além disso, fundamentado nos valores de r2, ausência de diferenças estatísticas entre todas as aplicações, e alta correlção entre os modelos da potência crítica convencional e AO3, podemos concluir que os testes de potência crítica convencional e AO3 em corrida atada na ENM, e LM em corrida atada na EM são metodologias viáveis para obtenção de parâmetros fisiológicos de capacidade aeróbia em unidade de potência mecânica, em ergômetro específico para corredores. Em relação aos parâmetros anaeróbios de capacidade, a aplicação de AO3 parece ser mais confiável pela maior coerência aos valores encontrados na literatura / Abstract: The aim of this study was to enable the use of nonmotorized treadmill tethered running (NMT) with load sensor for obtaining output power of runnung in physically active men. Furthermore, to analyze the correlation between the values of aerobic and anaerobic capacities obtained in the conventional test Critical Power and all-out three minutes in NMT, and lactate minimum test (LM) performed on the motorized treadmill (MT). For this ten males, mean age 23 ± 4 years attended the laboratory nine times for data collection. In the first two, anthropometric assessment and adaptation to the ergometer were implemented. After this adaptation, four visits to applying the conventional protocol for determining the critical power were used. For the test and retest of all-out three minutes (AO3) plus two visits, followed by a further application to the lactate minimum test were used. Importantly, an interval of at least 24 hours between all tests for muscle recovery was evaluated respected. Moreover, with the adaptation to escessão ergometers and anthropometry. The data collected were subsequently included in the statistical package Statistica 6.0 (Statsoft, USA), SPSS 16.0 for Windows (SPSS Inc., USA), checked for normal distribution using the Shapiro-Wilk test and homogeneity by Levene for decision use of parametric statistics (ANOVA One-way and Two-way when necessary and post hoc Newman-Keuls test for comparison of variables. Student's t test and Pearson correlation test and intra-class (ICC) for absolute agreement were also applied. for all analyzes the level of significance was set at p ? 0.05. principal findings of this study suggest that in AO3 in a nonmotorized treadmill tethered running NMT is a reproducible methodology. Moreover, based on r2 values, no statistical differences among all applications, and high correlção between models of conventional critical power and AO3, we can conclude that tests conventional critical power and AO3 in the NMT , and LM tethered running in MT are viable methodologies for obtaining physiological parameters of capacity aerobic mechanical power in unity, in particular ergometer for runners. Regarding anaerobic capacity parameters, the application of AO3 seems to be more reliable for greater consistency with the values found in the literature / Mestrado / Biodinâmica do Movimento Humano e Esporte / Mestra em Ciências da Nutrição e do Esporte e Metabolismo

WCDMA User Equipment Output Power Calibration / Uteffektskalibrering för WCDMA-telefon

Folkeson, Tea January 2003 (has links)
To save time in Flextronics high volume production, the time for test and calibration of mobile telephones need to be as short and accurate as possible. In the wideband code division multiple access (WCDMA) case, the output power calibration is the most critical calibration concerning accuracy. The aim with this thesis was to find a faster calibration method than the one that exists today and still retain accuracy. The Third Generation Partnership Project (3GPP) outlines the requirements of the output power and they must be thoroughly considered when choosing calibration method. Measurement accuracy and the behavior of the transmitter chain parameters also must be considered. The output power in the WCDMA phone studied is controlled by seven parameters. The parameters are characterized in this thesis, and are found to be too hardware dependent to be predicted or to be seen as predictions from each other. Since no parameter predictions are possible it was stated that all parameters have to be measured, and a new way of measuring them in a faster way is proposed. The principle of the new measurement method is presented, and the implemented software is tested and evaluated. The new method mainly makes use of the spectrum analyzer zero span function. The evaluation shows that the new method is faster than the original and retains accuracy. The measurement uncertainties even seem to diminish, which implicates decreased temperature dependence due to faster measurement time.

Conception et vérification formelles des interfaces homme-machine multimodales : applications à la multimodalité en sortie / Formal modelling and verification of multimodal human computer interfaces : output multimodality

Mohand Oussaïd, Linda 16 December 2014 (has links)
Les interfaces homme-machine (IHM) multimodales offrent à l’utilisateur la possibilité de combiner les modalités d’interaction afin d’augmenter la robustesse et l’utilisabilité de l’interface utilisateur d’un système. Plus particulièrement, en sortie, les IHM multimodales permettent au système de restituer à l’utilisateur, l’information produite par le noyau fonctionnel en combinant sémantiquement plusieurs modalités. Dans l’optique de concevoir de telles interfaces pour des systèmes critiques, nous avons proposé un modèle formel de conception des interfaces multimodales en sortie. Le modèle proposé se décompose en deux modèles : le modèle de fission sémantique qui décrit la décomposition de l’information à restituer en informations élémentaires, et le modèle d’allocation qui spécifie l’allocation des modalités et médias aux informations élémentaires. Nous avons également développé une formalisation B Événementiel détaillée des deux modèles : fission sémantique et allocation. Cette formalisation a été instanciée sur des études de cas puis généralisée dans un processus de développement B Événementiel cadre dans lequel s’inscrivent les modèles de fission sémantique et d’allocation. Cette formalisation a permis de procéder à la vérification de propriétés de sûreté, de vivacité et d’utilisabilité. / Multimodal Human-Computer Interfaces (HCI) offer to users the possibility to combine interaction modalities in order to increase user interface robustness and usability. Specifically, output multimodal HCI allow system to return to the user, the information generated by the functional core by combining semantically different modalities. In order to design such interfaces for critical systems, we proposed a formal model for the design of output multimodal interfaces. The proposed model consists of two models: the semantic fission model describes the decomposition of the information to return into elementary information and the allocation model specifies the allocation of the elementary information with modalities and media. We have also developed a detailed Event B formalization for the two models: semantic fission and allocation. This formalization has been instantiated on case studies and generalized in an Event B development process framework including semantic fission and allocation models. This formalization allows to carry out safety, liveness and usability properties verification.

Global Sustainability Accounting - Developing EXIOBASE for Multi-Regional Footprint Analysis

Wood, Richard, Stadler, Konstantin, Bulavskaya, Tatyana, Lutter, Franz Stephan, Giljum, Stefan, de Koning, Arjan, Kuenen, Jeroen, Schütz, Helmut, Acosta-Fernández, José, Usubiaga, Arkaitz, Simas, Moana, Ivanova, Olga, Weinzettel, Jan, Schmidt, Jannick, Merciai, Stefano, Tukker, Arnold 26 December 2014 (has links) (PDF)
Measuring progress towards sustainable development requires appropriate frameworks and databases. The System of Environmental-Economic Accounts (SEEA) is undergoing continuous refinement with these objectives in mind. In SEEA, there is a need for databases to encompass the global dimension of societal metabolism. In this paper, we focus on the latest effort to construct a global multi-regional input-output database (EXIOBASE) with a focus on environmentally relevant activities. The database and its broader analytical framework allows for the as yet most detailed insight into the production-related impacts and "footprints" of our consumption. We explore the methods used to arrive at the database, and some key relationships extracted from the database.

A systematic review of literature reporting on the strategies/interventions addressing research capacity building in new academics

Simons, Abigail January 2014 (has links)
Magister Artium (Psychology) - MA(Psych) / It is often assumed that postgraduate students and neophyte academics have the capacity to conduct research independently. Thus, upon qualification, it is expected of postgraduate students and academics to conduct research independently, publish their findings, meet publication targets and to supervise student research towards completion. However, the transition from postgraduate student or clinician to academia is considered very challenging as they are often not prepared for the multiple changes they will embark on upon entry into the Higher Education sector. As a result, various programmes and frameworks have been introduced to assist new academics in enhancing their research capacity. Such strategies included but were not limited to, writing retreats, peer monitoring, and dedicated time. However, these interventions reported on in literature are from primary sources and fail to comment on either the methodological rigour or the quality of the studies investigating these interventions. Thus there exists a gap in the literature for filtered information that has been systematically evaluated for methodological rigour and coherence. The present study aimed to establish an empirical base (filtered evidence) of literature reporting on strategies or interventions aimed at addressing research productivity in new academics. The study incorporated a systematic review methodology to identify appropriate literature for inclusion, evaluate literature for methodological quality and provide a meta-synthesis of the findings of included studies. The review considered studies, reporting on strategies or interventions with new academics during the period of 2000-2013. The review was conducted along three levels. Firstly, identification of potential titles, whereby keywords were combined and a comprehensive search of databases available at the University of the Western Cape library was initiated. Published research was also retrieved through mining the reference list of all included reports and articles. Secondly, a pair of reviewers worked together by screening the abstracts which were retrieved based on the titles identified, and thirdly, the abstracts that were successfully screened moved forward to full text reading. These studies were evaluated for methodological quality using the critical appraisal tool. Eligibility for inclusion was determined by a threshold score of 61%. As a result, the title search yielded a search result of 755, from these only 63 titles were selected for possible inclusion. The abstract screening resulted in the exclusion of 35 articles and 28 were included. After the critical appraisal, 15 articles were excluded. The findings of the present study revealed that there is good quality research on research capacity building for neophyte academics, as assessed on methodological rigour and coherence. Seven articles attained the threshold score (61% and above) for inclusion in the final summation and meta-synthesis. Evidence suggested that there are various interventions which have been implemented successfully to enhance research capacity building. The meta-synthesis revealed four core approaches to developing research capacity, namely mentoring approaches, theoretical formulations, research/evidence-based investigation as well as a multidimensional and integrated approaches. These approaches were aimed at bridging that gap between research and teaching and developing competent researchers. The core feature that emerged from these approaches was that successful or effective strategies have to include numerous components such as individual characteristics (motivation), effective leaders and institutional characteristics (rewards, incentives and resources). It was found that these components were integrated and often reciprocally influencing. Ethics clearance was obtained from the relevant committees at UWC. Furthermore, plagiarism and collaboration was taken into account as this study forms part of a larger project.
