Texto completoEsta dissertação tem o objetivo de compreender o que "impacto" significa quando se fala em investimentos de impacto, focando na sua medição e prática através da indústria. Uma breve revisão de literatura permite entender as principais características da indústria, identificar os atores envolvidos e as últimas iniciativas para a medição de impacto. O estudo de caso com a GoParity, uma start-up portuguesa que atua como intermediadora no mercado de investimentos de impacto, oferece uma perspectiva mais próxima do funcionamento da indústria, particularmente nos desafios que existem para avaliar, monitorar e gerir impacto. As conclusões sugerem que, apesar sde desafios acerca da medição do impacto, uma combinação de ferramentas, vontade organizacional e recursos podem fortalecer a qualidade e escala dos investimentos de impacto para solidificar mudanças sustentáveis na sociedade.
This dissertation aims to comprehend what "impact" means within impact investments, focusing on its measurement and its practice throughout the industry. A brief literature review allows us to understand the main features of the industry, the involved actors and to identify the latest initiatives for impact measurement. The case study of GoParity, a Portuguese start-up acting as an intermediary in the impact investment market, is expected to offer a closer insight into the working of the industry, particularly on the challenges it faces to assess, monitor, and manage impact. The conclusions suggest that despite challenges surrounding measurement, a better built combination of tools, organizational will and resources can strengthen the quality and scale of impact investments to solidify lasting changes in society.

Texto completoAll organizations have impacts that affect economy, society and the natural environment. Academics from different streams of research (i.e. business and society studies, accounting, strategic management) propose several definitions of “social impact” (Latané, 1981; Burdge & Vanclay, 1996; Emerson et al., 2000; Clark et al., 2004). All these definitions describe, more or less explicitly, the concept of “change”, being each one based on the Theory of Change (Weiss, 1972; Anderson, 2004) – i.e., the change that an organization can produce in people’s way of life, culture, personal and property rights, fears and aspirations, but also with respect to community, political systems, environment, health and wellbeing. The measurement of social impact leads the organization to consider the changes on stakeholders as a result of the set of cause-effect relations proposed by the theory of change. The objective of social impact measurement thus is to understand, in social, environmental and economic terms, changes that have occurred in stakeholders’ lives because of organizations activities, in order to communicate it (Nicholls et al, 2009). Despite a growing interest on social impact measurement, academic production in the topic is still scarce. The present Ph.D. thesis contributes to the ongoing discussion by focusing on the theory, concepts and tools to measure social impact. In particular, two context of analysis are at issue: ethical finance and entrepreneurship education. The work consists of three papers. The first research wants to provide a review of the literature on the issue of measuring the social impact in the context of ethical finance, the second paper is an action research on a methodology for measuring the social impact of ethical banks developed through the extreme case study of Banca Popolare Etica, and the third research concerns the context of entrepreneurial education and aims at studying the impact of an MBA program on the antecedents of entrepreneurship intention of students in Ghana. More in details, the first paper is entitled “Review of impact assessment methodologies for ethical finance”. This paper provides a comprehensive review of the literature on measuring the social impact in ethical banks. Specifically, we discuss the approach of ethical banks to social impact and social impact measurement considering several studies and frameworks of analysis, then proposing a list of indicators and outcomes to be used to highlight the social impact of ethical banks’ activities. We also point out some gaps in the literature that we left as questions open for future research. The research was carried on with two partners: the Fédération Européenne des Banques Ethiques et Alternatives (FEBEA) and the Institute of Social banks (ISB). The title of the second paper is: “Measurement of social impact in financial institutions: the case of Banca Popolare Etica”. This is an action research on a methodology for measuring the social impact of ethical banks, grounded on the case study of Banca Popolare Etica. We use a dataset of 1,385 organizations and 1,324 individuals, recipients of funding, to study the measurement of the social impact of the projects funded. Integrating in a single assessment process (both quantitative and qualitative) various methodologies generally singularly used for the measurement of social impact (Social Return on Investment (SROI), Impact Reporting Investment Standards (IRIS) and storytelling), the case shows how the traditional limitations of methodologies to measure social impact can be overcome. The third and last study is entitled “Does entrepreneurial education impact on antecedents of entrepreneurial intention? An analysis of an Entrepreneurship MBA in Ghana”. This study has the aim to analyze the effects of an entrepreneurship education program, on the antecedents of entrepreneurial intention of students in a developing country. The study analyzes the results of an impact research conducted with participants to a specific entrepreneurship education program: the “E4impact MBA”, held by the Catholic Institute of Business and Technology – CIBT in Accra, Ghana. The mixed method design employed, was an explanatory approach (Creswell, Plano Clark et al., 2003) with a quasi-experimental design (Cohen and Manion, 1989) featuring both pre-post tests and self-perceived change measures. We assessed changes in entrepreneurial psychological characteristics (Need for achievement, Self-efficacy, Locus of control; Risk taking propensity; Tolerance for ambiguity) and personal skills and knowlwdge (Creativity, Knowledge, Flexibility, Networking and Analysis) following the extended model of the Theory of Planned Behaviour. The analysis shows that the entrepreneurship education program has a strong impact on psychological and cognitive antecedents of entrepreneurial intentions. That is, participation in entrepreneurship education program can positively influence students’ entrepreneurial intentions and perceived behavioral control supporting the idea that universities have a key role in shaping and fostering entrepreneurial intentions and abilities through entrepreneurship education program.

This research aims to study private equity impact investments based on a comparative analysis of different private equity funds practices. In particular, it examines how the requirements of impact investing are encompassed in private equity investment processes. First, a literature review was conducted to better define impact investing and assess the complementarity of private equity with impact investing. Secondly, a qualitative study was pursued based on a panel of interviews. Interviewees are investment professionals working for private equity firms with interests in impact investing. The analysis of the interviews indicates a certain commonality of the investment methods between the funds paneled whether they are pure player private equity impact investors or traditional private equity firms investing for impact. Beyond the proximity between investment strategies, the research also shows a strong focus on in-house impact targeting and measurement, with little resort to external tools. Such flexibility negatively affects the readability of impact performance from a market perspective. The research concludes impact investing still has to go through a standardization process to gain global recognition as a private equity segment.
Esta pesquisa tem como objetivo de estudar os investimentos de impacto de private equity com a base de uma análise comparativa de diferentes práticas de fundos de private equity. Em particular, examina como os requisitos de investimento de impacto estão abrangidos nos processos de investimento em private equity. Em primeiro lugar, uma revisão da literatura foi feita para melhor definir o investimento de impacto e avaliar a complementaridade do private equity com os investimentos de impacto. Em segundo lugar, um estudo qualitativo foi realizado com base de um painel de entrevistas. Os entrevistados são profissionais de investimento que trabalham para empresas de private equity com interesses em investimentos de impacto. A análise das entrevistas indica uma certa semelhança dos métodos de investimento entre os fundos estudados que eles sejam unicamente investidos em impacto o que sejam fundos de private equity que fazem investimentos de impacto além de investimentos tradicionais. Além da proximidade entre as estratégias de investimento, a pesquisa também mostra um forte foco em processos de segmentação e de medida do impacto internos, com pouco recurso para ferramentas externas. Essa flexibilidade afeta negativamente a legibilidade da realização do impacto por parte do mercado. A pesquisa conclui que os investimentos em impacto ainda precisam passar por um processo de padronização para obter reconhecimento global como um segmento de private equity.

Texto completoThis thesis is about the measurement of inequality of opportunity and its impact on economic growth. Chapter 1 studies the axiomatic properties of two prominent measurement approaches. In both cases, the population is partitioned into groups of people sharing the same circumstances, those income determinants that are beyond individual control (e.g. sex or parental background) and that shape one's opportunities. Inequality of opportunity is then measured by applying a1 inequality index over a counterfactual distribution where each individual is attributed the representative income of his group. The first approach takes the representative income of a group to be its arithmetic mean. When a large number of small-sized groups are considered, these means can be poorly estimated. To mitigate this issue, the second approach, called parametric, assumes that circumstances have no interaction effect and takes this representative income to be the OLS predicted value of income regressed on circumstances. Chapter I shows that the parametric approach has poor axiomatic properties, especially with respect to a between-group version of the transfer principle. Chapter 2 provides a methodology to circumvent the current lack of microdata on parental background circumstances, a major driver of inequality of oppo1tunity. The idea is to retrieve the parental background of adults living with their parents thanks to the structure of household survey data, and then to apply a missing data procedure -multiple imputation -to obtain estimate of inequality of opportunity that are representative of the overall adult population. These estimates are shown to be close to their "true" counterpa1ts, based on direct questions about parental background contained in the Brazilian PNAD 1996 survey. Chapter 3 empirically investigates a recent and promising explanation for the inconclusiveness of traditional growth-inequality literature: income inequality does not matter for growth while its components -inequality of opportunity and the residual one, inequality of effort -do. This explanation is validated in Brazil at the municipality level over the period 1980-20 l 0, where inequalities of opportunity and effort are respectively detrimental and beneficial to subsequent growth, as expected. Their effects are robust and significant, in contrast to that of total income inequality

The purposes of this study were to describe the relationship of sociodemographic and biomedical characteristics to health perceptions among individuals with rheumatoid arthritis (RA) and to identify which functional measures are associated with one's health perceptions. Data were extracted on 395 individuals with classical or definite RA for a secondary data analysis. These data had been collected between 1978 and 1982 using the Arthritis Impact Measurement Scales (AIMS), a reliable and valid self-administered questionnaire on health status. Sociodemographic information included age, sex, current marital status, occupation, income, and engagement in a productive role. Biomedical data included a respondent's disease duration, disease severity, and comorbid conditions. A dependent variable which classified health perceptions (HP) was constructed from two AIMS questions concerning self-assessed current health and belief in the ability to resist illness. Using subjects' sociodemographic characteristics and biomedical indicators as determinants of health perception classifications (HPC), repondents were grouped into nodes through a recursive partitioning technique (CART). Income, disease activity, current marital status, age, and comorbidity were identified by CART as important and interactive determinants of HPC. In the second phase of analysis, differences in function between HP groups on the nine AIMS scales were explored using subjects' self-assigned HP groups, while controlling for sociodemographic and biomedical characteristics and their potential interactive effects as they had been identified by the CART algorithm. Analysis of these differences demonstrated that the explanatory sociodemographic and biomedical variables used in this study both explained and masked significant differences between HP groups on certain functional measures. Finally, the analysis determined which functional measures were most associated with self-assigned HP using a stepwise logistic regression model. Anxiety, physical activity and household activity formed an overall explanatory model of HP. Physical activity and depression were associated with current health perceptions. Perceived resistance to illness was related to subjects' levels of anxiety and household activity.

Texto completoThe purpose of this study was to determine if a difference existed between student learning, using the Missouri Assessment Program (MAP), and Professional Learning Community (PLC) implementation within fifth-grade populations in the state of Missouri. The following research questions were utilized to drive the research: What is the difference in MAP communication arts scores for fifth-grade students in Missouri districts that have adopted the Missouri PLC model as compared to those that have not adopted the Missouri PLC model? What is the difference in MAP math scores for fifth-grade students in Missouri districts that have adopted the Missouri PLC model as compared to those that have not adopted the Missouri PLC model? What are the perceptions of administrators of Missouri PLC districts regarding the Missouri PLC program and student achievement? Three years of math and communication arts data were analyzed in this study. Yearly mean scores were compared by applying a t-test to determine if a statistical significance existed between PLC implementation and student learning. Missouri PLC exemplary schools' data were analyzed and compared to data of like-demographic, non-PLC implementing schools. The data revealed, in the area of communication arts, no statistical significant difference in student achievement between PLC exemplary schools and non-PLC schools. These findings led to the decision to not reject the null hypothesis and not support the alternative hypothesis. A statistical significant difference was found in the area of math, and an overall conclusion was drawn that supported the alternate hypothesis and rejected the null hypothesis. In addition, interviews were conducted with Missouri PLC exemplary school administrators to gain perspectives into the daily successful workings and effect of the Missouri PLC model on student achievement. Administrators from the PLC exemplary schools attributed gains in student achievement to PLC implementation.

Texto completoNegli ultimi anni un nuovo rischio ha iniziato ad emergere per i veicoli spaziali orbitanti attorno alla Terra: i detriti spaziali. Questo termine descrive oggetti di origine umana in orbita attorno alla Terra che non hanno più uno scopo utile. Il presente lavoro descrive tecniche di misura per stimare e ridurre il rischio creato da micrometeoriti e detriti spaziali (MMOD) ai veicoli spaziali. Le principali aree di ricerca sono: • Fenomenologia dell’impatto, metodologia per la stima del rischio, metodi di progettazione; • Metodi sperimentali (ossia tecniche di accelerazione e strumentazione per la diagnostica); • Modelli ingegneristici (ossia misure degli effetti dei MMOD e derivazione delle equazioni di danno). Gli obiettivi e i contributi personali legati a queste aree di ricerca sono presentati relativamente a: • Sviluppo della strumentazione del laboratorio per la simulazione di impatti iperveloci presso il CISAS (Centro Interdipartimentale Studi ed Attività Spaziali) “G. Colombo”, ossia evoluzione del cannone bistadio a gas leggero e progettazione relativa a componenti di due cannoni monostadio a gas leggero, uno per il CISAS e uno per la Cranfield University, UK; • Attività sperimentale relativa allo studio degli impatti, dove sono stati sviluppati strumenti per la caratterizzazione di ejecta e per il rilevamento di impatti primari; • Derivazione delle equazioni di danno, questo ha portato allo sviluppo di nuove Equazioni di Limite Balistico, aventi base statistica e che forniscono un nuovo scenario riguardo il futuro della progettazione di scudi per i MMOD. Queste equazioni sono sviluppate per definire le condizioni di impatto (ossia diametro e densità del detrito, velocità e angolo di impatto) che risultano per il valore di soglia relativo al fallimento di uno specifico componente o sottosistema di un veicolo spaziale. I principali obiettivi di questa ricerca sono stati raggiunti e hanno portato a: • Studio gasdinamico e progettazione del sistema ferma sabot per un nuovo cannone monostadio a gas leggero per il laboratorio per impatti iperveloci presso il CISAS; • Progettazione della camera per gli impatti e del sistema ferma sabot per il cannone monostadio a gas leggero presso la Cranfield University, UK; • Progettazione della sezione ad alta pressione e della struttura di supporto per il nuovo cannone bistadio a gas leggero presso il CISAS; • Progettazione ed evoluzione di uno strumento per la caratterizzazione di ejecta; • Progettazione di uno strumento per misure relative a impatti primari; • Sviluppo di una metodologia per derivare equazioni di danno su base statistica per i satelliti Cosmo-Skymed; • Sviluppo di una metodologia per derivare equazioni di limite balistico su base statistica per strutture inflatable.
Devivier, Cédric. "Damage identification in layered composite plates using kinematic full-field measurements". Troyes, 2012. http://www.theses.fr/2012TROY0017.
Texto completoThis work focuses on the development of an experimental technique which can help to define the key parameters for post-impact behaviour of laminated composite panels. To address this issue, finite element models were built to represent delaminations based on the observations of CT-scans of impacted samples. The results of these models have been correlated to experimental data obtained using a slope fullfield measurement technique: deflectometry. This work also develops a new damage indicator based on the application of the virtual fields method to compute a local equilibrium gap. The procedure is first presened and then applied to beam and plate samples. The experimental results illustrate the remarkable sensitivity of this measurement method as it captures the effect of very small amount of damage and shows that the simple numerical models need to be refined to present a better correlation to experimental results. The damage indicator successfully detects contours of damaged areas when sufficient spatial information is available. It is believed that pursuing the present work could lead to an invaluable tool to help design engineers

Texto completoThis work focuses on the development of a novel experimental procedure for high strain rate testing of materials. The underpinning novelty of this work is the use of the full-field acceleration maps as a volume distributed load cell, avoiding the need for impact force measurement. To identify the constitutive parameters of materials from the full-field data, the Virtual Fields Method (VFM) based on the principle of virtual work is used here. In dynamics, using the VFM, it is possible to define particular virtual fields which can zero out the virtual work of the external forces. Instead, the acceleration obtained through second order temporal differentiation from displacement can be used as a load cell. Finally, the elastic parameters can be identified directly from a linear system which is built up through rewriting the principle of virtual work with as many independent virtual fields as unknowns. Thus, external force measurement is avoided, which is highly beneficial as it is difficult to measure in dynamics. This procedure is first numerically validated through finite element simulations and then experimentally implemented using different impact setups. Both results confirm that inertial effects can be used to identify the material parameters without the need for impact force measurements, also relieving the usual requirements for uniform/uniaxial stress in SHPB like test configurations. This exciting development has the potential to lead to new standard testing techniques at high strain rates
