Os projetos cujos dados foram avaliados pertencem ao Programa Educar para Vencer, resultante de uma política pública para a educação realizada pela Secretaria da Educação da Bahia. A partir da pergunta inicial “como as competências dos dirigentes escolares se relacionam com o desempenho das escolas estaduais da Bahia?” foram revistas as literaturas sobre os conceitos de competência e de desempenho escolar, adotadas duas dimensões como fonte de indicadores da competência do diretor escolar, a funcional e a construtivista, e, para o desempenho escolar, adotada a dimensão proficiência do aluno. Com o objetivo de responder a pergunta em destaque neste resumo foram elaboradas, à luz da literatura revisada, quatro hipóteses. A análise das relações e os testes das hipóteses foram feitos com base em dados montados a partir do cadastro das escolas estaduais da Bahia no Censo Escolar de 2004. Do universo de 1867 escolas, 1193 atenderam ao critério da pesquisa: possuir diretor que participou do processo de certificação ocupacional realizado pela Fundação Luís Eduardo Magalhães para a Secretaria da Educação da Bahia e gerenciou a mesma unidade escolar ao longo de todo ano letivo de 2004. Como ferramenta de análise, utilizou-se os softwares Excel e SPSS e, como métodos estatísticos, a correlação linear simples e a regressão linear múltipla. Para ampliar o conhecimento sobre os resultados das relações encontradas, foram introduzidos fatores de teste relacionados teórica e empiricamente com o desempenho escolar ou a competência do diretor: idade do diretor, porte da escola, complexidade da gestão, existência de projeto pedagógico, disponibilidade de livros, a satisfação com as condições de trabalho e desenvolvimento municipal. As conclusões chegadas a partir deste estudo seguiram as expectativas iniciais: (1) há uma tendência de existir mais alto desempenho dos alunos onde há diretores mais competentes, na dimensão funcional; (2) a competência do diretor escolar, na dimensão construtivista, relaciona-se com mais intensidade e de maneira mais significativa com o desempenho escolar do que a competência na dimensão funcional; (3) a competência do diretor escolar, na dimensão construtivista, apresentou ser, no conjunto das relações estabelecidas com o desempenho escolar, o fator interno à escola de maior relevância; (4) há uma tendência de maior desempenho escolar quando há uma maior taxa de competência da equipe, na dimensão funcional. / Salvador

Given that these class involve the Brazilian funds which most resemble the foreign hedge funds, traditional measures such Sharpe’s Ratio and Jensen’s Alpha may not be appropriate to analyze the ability of its managers to add extraordinary value. The measure used is related to the paper of Amin and Kat (2003), which compares the expected return of the fund with the returns generated by a strategy that, in the absence of arbitrage, has no cost to be implanted and yields a risk-free rate. With monthly data of 107 multimarket funds in the period from January 2005 to August 2011, the main results showed that the average net performance of the funds was lower than zero. On the other hand, the average gross performance (measured with returns before management fees and performance) was statistically greater than zero, indicating that managers can add extraordinary value, but these gains are eroded by management and performance fees. The work also showed that periods of crisis not only have a significantly (and negative) impact on the performance of the funds, but also on the relationship of this performance with its determinants. Thus, the results of this work may have important contributions to the development of the theory on investment fund performance in Brazil, both because it involves the use of a more adequate analysis tool and considers the crisis as a variable that moderates the relationship between performance and its determinants. / A proposta deste trabalho foi analisar a performance dos fundos multimercados brasileiros com uma medida mais adequada às características da distribuição de frequência de seus retornos. Tendo em vista que estes são os fundos brasileiros que mais se assemelham aos hedge funds estrangeiros, medidas tradicionais, como o Índice de Sharpe e o Alfa de Jensen, podem não ser adequadas para analisar a habilidade dos gestores em agregar valor extraordinário para os seus cotistas. A medida utilizada está relacionada com o trabalho de Amin e Kat (2003), que compara o retorno esperado do fundo com o retorno gerado por uma estratégia que, na ausência de arbitragem, possui custo zero para ser implantada e rende a taxa livre de risco. Com dados mensais de 107 fundos multimercados no período de Janeiro/2005 a Agosto/2011, os principais resultados mostraram que a performance líquida média dos fundos foi estatisticamente menor que zero. Já a performance média medida com base nos retornos brutos (antes das taxas de administração e de performance) foi estatisticamente superior a zero, indicando que os gestores podem até agregar valor extraordinário, mas esses ganhos são corroídos por taxas de administração e de performance. Destacam-se também resultados mostrando que períodos de crise impactaram significativamente não só a performance dos fundos, mas também a sua relação com seus determinantes. Desta forma, entende-se que os resultados podem introduzir importantes contribuições para a construção da teoria sobre a performance de fundos de investimentos brasileiros, tanto por envolver a utilização de uma ferramenta de análise mais adequada quanto por considerar a crise como uma variável moderadora da relação entre a performance e seus determinantes.

It will indicate to a small investor what kind of information to look for in the funds prospect. In order to do so, the observed performances of several different intervals were regressed against determinants found in the existing literature. As a result from this work, the characteristics that statistically mostly contribute to an increased performance are: Investment funds with active management that focuses on office buildings located in the major central districts. / Esta dissertação busca identificar as características indicativas de desempenho superior de Fundos de Investimento Imobiliário (FII) com quotas negociadas em bolsa. Desta maneira visa subsidiar um investidor leigo de quais informações o mesmo deve procurar em um prospecto de um fundo de investimento a fim de selecionar o seu fundo. Para tanto foi aplicada uma metodologia de regressão simples da rentabilidade observada em diversos intervalos de tempo contra variáveis geralmente indicativas de desempenho levantadas na revisão bibliográfica. Como resultado deste trabalho, destacaram-se como características estatisticamente relevantes para uma maior rentabilidade fundos de gestão ativa, sem imóvel definido, cuja política de investimento visa lajes corporativas localizadas nos grandes centros urbanos.

Agro-based climate adaptation has gained traction in scholarly and policy circles, albeit with limited comprehensive empirical evidence on the pathways of crop sector-specific adaptation approaches in sub-Saharan Africa (SSA). To stem this knowledge gap, this study examines the evolution of farm-based climate adaptation practices in the vegetable subsector of Cameroon’s western highlands. Specifically, we (i) explore the different adaptation practices, (ii) estimate the determinants of farm-based adaptation, and (iii) determine the effects of farm-based adaptation on vegetable performance. Data were collected from a representative sample of farming households (N = 150) in two communities using a semi-structured questionnaire, complemented by key informant interviews (N = 10) and focus group discussions (N = 5). The Product Moment Correlation established an evolution from traditional practices to more modern scientific practices with changing climate, as vegetable farmers shifted from using local seeds to improved ones, intensified pest control strategies and adopted water pump-based irrigation practices. The binary logistic regression model revealed that belonging to farming groups, increase in income and access to credit significantly explained farm-based adaptation (p = 0.041). Furthermore, farm-based practices were significantly reflected in crop performance, mirrored through an increase in vegetable quantity (p = 0.003) and perceived quality (p = 0.046). The results suggest the need for further research to blend traditional and conventional adaptation approaches, and to create enabling environments to foster social capital (belonging to groups) and access to credit as key levers for climate-resilient vegetable production in the western highlands of Cameroon.

Automation ist heute in allen Lebensbereichen zu finden. Die „zuverlässige“ Automation soll den „unzuverlässigen“ Menschen (Benutzer/Operateur) entlasten, kompensieren, teilweise sogar ersetzen. Eine Automation kann jedoch Fehler machen, wurde sie doch von „unzuverlässigen“ Menschen (Entwicklern) entwickelt. Deshalb verfolgte das Projekt ATEO einen in der Forschung bisher nur theoretisch betrachteten Ansatz zur Optimierung der Funktionallokation zwischen Mensch und Maschine. Hierbei handelt es sich um die Optimierung der Arbeitsteilung zwischen Operateuren und Entwicklern von komplexen, dynamischen, technischen Systemen inklusive Automationen. Diese Dissertation beschäftigt sich mit den Leistungsdeterminanten dieser Entwickler. Die bisher in der Literatur beschriebenen Befunde zu diesen Leistungsdeterminanten wurden zu einem deskriptiven „Modell der Leistungsdeterminanten von Entwicklern“ zusammengetragen. Anschließend wurde die potentielle Leistungsdeterminante „Informationsverfügbarkeit“ unter Einsatz von 90 professionellen Entwicklern experimentell beleuchtet. Zur Erfassung der abhängigen Variable „Güte der Automatikkonzepte“ wurde ein Bewertungsinstrument entwickelt. Zudem wurde die Komplexität der verwendeten Versuchsumgebung „Socially Augmented Microworld“ experimentell erhöht, damit für professionelle Entwickler die Konzeption von Automatiken nicht zu leicht ist. Zusätzlich wurde eine Automatiksoftware zur Implementierung und Konfiguration der von den Entwicklern konzipierten Automatiken entwickelt. Durch die Untersuchung konnte gezeigt werden, dass die Kontrollvariablen „Erfahrungsindex“, „Witzanzahl“ und „Leistungsmotiv HE“ einen höheren Einfluss auf die Güte des Konzeptions¬ergebnisses haben als die systematisch variierte „Informationsverfügbarkeit“. Erst durch Eliminierung der Wirkung dieser Kontrollvariablen konnte ein signifikanter Einfluss der zur Verfügung gestellten Informationen auf die Güte der Automatikkonzepte nachgewiesen werden. / Automation is currently to be found in all aspects of life. “Reliable” automation is believed to take the pressure off, to compensate, or even displace the “unreliable” human (user/operator). However, as a consequence of being developed by “unreliable” humans (developers) automations can also be susceptible to error. The Project ATEO (division of work between developers and operators) pursues an, so far in researches only theoretical considered, approach to optimize the function allocation between human and machine. It is about an optimization of the division of responsibilities between operators and developers of complex, dynamic, technical systems including automations. This thesis concerns the performance determinants of these developers. Literature regarding the previous findings of performance determinants research were gathered into a descriptive "model of developers'' performance determinants". Subsequently, the potential performance determinant "information availability" was examined experimentally by using 90 professional developers. To capture the dependent variable "quality of automation concepts" an assessment tool was developed. Moreover, the complexity of the used test environment "Socially Augmented Microworld" was experimentally heightened to ensure that for these developers the conception of automatic functions was not too easy. Also, an automations software was designed to enable the implementation and configuration of the developer-created automations. The results of the experiment with the professional developers showed that the control variables “experience index”, “number of jokes” and “achievement motive hope of success” had a higher influence on the quality of the design result as the systematically varied "information availability". Only by eliminating the effect of these control variables a significant influence of the performance determinant “information availability” on the quality of automation conceptions was attested.

Over the last decades, Mergers and Acquisitions (M&A) have become key strategic alternatives to organic growth, enabling firms to expand in new geographies, broaden their product or service portfolios, increase their market power or diversify their business activities, for instance. Historically, although M&A deals have occurred in cyclical patterns, the number of transactions as well the total amount invested have followed an increasing trend. For instance, in 2021, the number of M&A deals conducted worldwide even peaked at an absolute record of 63,215 deals, for a total amount of $5,800 billion, comparable to the annual GDP of a country like Japan. Although the literature on M&A is vast and multi-disciplinarian, the performance of such transactions as well as their influencing factors have remained debated issues. This paper-based dissertation investigates the implications of corporate social responsibility (CSR) on financial markets’ anticipations in the context of M&A announcements. The first manuscript (Manuscript A) corresponds to a literature review on the determinants to financial markets’ reactions around M&A announcements. The second manuscript (Manuscript B) investigates the impact of both acquirers- and targets’ CSR engagements as well as their CSR profiles distance on synergetic gains anticipated by financial markets around M&A announcements. The third manuscript (Manuscript C) focuses on the impact of acquiring firms’ CSR engagement on the accuracy of financial markets’ anticipations with regards to the long-term operating performance of M&A deals. The fourth manuscript (Manuscript D) analyses whether acquirers’ CSR performance impacts M&A premia, since the premia offered to target shareholders contain acquiring managements’ anticipations regarding potential synergetic gains and are by the way critical to the deals’ value creation processes.
