Blau, Winfried. "Ontologically Founded Causal Sets: Constraints for a Future Physical Theory of Everything." Winfried Blau, 2016. https://slub.qucosa.de/id/qucosa%3A7600.
Full textAbstract:
The paper is located on the border between physics, mathematics and philosophy (ontology). The latter is required to embed the dualistic by nature mathematics into a monistic metatheory. It is shown, that a consequent philosophical monism and an approach which starts from the origin of the universe imposes significant constraints on a physical Theory-of-Everything. This may be helpful for finding such a theory. A philosophical system that is monistic and at the same time structured clear enough to be compatible with mathematical thinking is the Hegelian dialectic logic. With the aid of this logic the necessary existence of a causal chain embedded in the general, unconditional and timeless being is proved constructively. In the causal chain our entire reality is coded. It is termed by Hegel as determinate being in contrast to being. The chain has a beginning, representing the birth of the universe (big bang) and the beginning of time. It is isomorphic to the natural numbers. The half-ring structure of the natural numbers induces a secondary causal network. Thus the ontological approach results in a special version of the theory or causal sets. The causal network is topologically homeo-morphic to an infinite dimensional Minkowski cone. Each prime number corresponds to a dimension. Hypothetical small 'bumps” of 4D spacetime (Brane) in the direction of the extra dimensions of the Minkowski manifold mean topological defects, which can be interpreted as curvature of spacetime. This means a bridge to the general theory of relativity. On the other hand, the bumps may be interpreted as objects with which one can handle similar to the strings in string theory.<br>Die Arbeit bewegt sich im Grenzgebiet zwischen Physik, Mathematik und Philosophie (Ontologie). Letztere wird benötigt, um die vom Wesen her dualistische Mathematik in eine monistische Metatheorie einzubetten. Es wird gezeigt, dass ein konsequenter philosophischer Monismus und ein Denken vom Ursprung des Universums her einer physikalischen Theorie-von-Allem erhebliche Randbedingungen auferlegen. Für das Auffinden einer solchen Theorie kann das hilfreich sein. Ein philosophisches System, dass monistisch ist und zugleich klar genug strukturiert um mit der mathematischen Denkweise kompatibel zu sein ist die Hegelsche dialektische Logik. Unter Zuhilfenahme dieser Logik wird die notwendige Existenz einer in das allgemeine, unbedingte und zeitlose Sein eingebetteten, aber vom Chaos dieses Seins unbeeinflussten kausalen Kette konstruktiv bewiesen. In dieser kausalen Kette ist unsere gesamte Realität codiert, von Hegel als Dasein im Gegensatz zum Sein bezeichnet. Die Kette hat einen Anfang, der den Anfang des Universums und den Anfang der Zeit darstellt. Sie ist isomorph zu den natürlichen Zahlen. Deren Halbring-Struktur induziert ein sekundäres kausales Netzwerk. Somit ist das Ergebnis der ontologischen Herangehensweise eine spezielle Version der Theorie der kausalen Mengen. Das Netzwerk ist topologisch homöomorph ist zu einem unendlich dimensionalen Minkowski-Kegel. Jeder Primzahl entspricht eine Dimension. Hypothetische kleine „Ausbeulungen“ oder „Bumps“ der 4D-Raumzeit (Brane) in Richtung der Extradimensionen der Minkowski-Mannigfaltigkeit bedeuten topologische Baufehler, die sich als Krümmung der Raumzeit interpretieren lassen und eine Brücke zur allgemeinen Relativi-tätstheorie darstellen. Auf der anderen Seite lassen sich die Ausbeulungen der Brane als Objekte deuten, mit denen man ähnlich umgehen kann wie mit den Strings der Stringtheorie.

Coombs, Coutanya Moultry. "The Experience of Founder's Syndrome in Nonprofit Organizations Founded by Women." ScholarWorks, 2019. https://scholarworks.waldenu.edu/dissertations/7373.
Full textAbstract:
Gaps exist in the literature on knowledge of how founder behavior affects volunteers and employees in nonprofit organizations. Through exploration of founder relationships with volunteers and employees, this study fills some of those gaps and adds to the body of knowledge of how those relationships are perceived by founders, volunteers, and employees. The purpose of this narrative study was to address the question of the impact of founder behavior on founders, employees and volunteers in nonprofit women's organizations founded by African American and Caucasian women. The theory of psychological ownership was used as the framework to understand founder behavior. The qualitative narrative inquiry design consisted of interviews with 12 participants who work for nonprofit organizations that provide empowerment services to women. Themes such as control, lack of strategy and support, and silenced voices emerged as responses to the question of the impact of founder behavior on the organization. The results indicate that founders, employees, and volunteers report a need for clear policies, role assignments, procedures, and organizational goals. Founders are oblivious to the impact of their behavior on the organization and are not aware of the available resources that may exist in their communities. Implications include state level nonprofit policy that funds training for nonprofit organizations around the themes examined in this study. Recommendations for future research include examination of internal issues and structures related to an organization's growth. The result of this study may lead to increased understanding of perceptions of the operations of nonprofit organizations which may impact nonprofit organizations' abilities to meet the goals of their mission.

Moyer, Matthew T. "Use of an Interactive Web-based Platform, Founded on Constructs from the Social Cognitive Theory, to Benefit Eating Competence." OpenSIUC, 2014. https://opensiuc.lib.siu.edu/dissertations/840.
Full textAbstract:
Since Web-based interventions have a significantly high rate of attrition ranging from 99.5% to 77.5%, the researcher employed an instrumental case study approach to understand compliance in a Web-portal. The specific issue for this study was attrition rates and how SCT constructs affected eating competence. Qualitative data provided ground zero insight to a complex issue that was further understood. To better understand the phenomenon, participants that registered for the 30-day study and the software developer were interviewed. All interviews (n=6) were transcribed and data from the transcriptions were transformed from dialogues, into categories, then themes, and finally into concepts. Five guidelines to keep attrition rates low was the outcome of the data analysis. Having a nation interested in the Internet and at the same time faced with an obesity epidemic seemed to be a good fit for researching a method to promote eating competence with interactive technology. Eating competence intertwines four components: (1) attitudes about eating and the enjoyment of food (2) accepting new food to add variety to your diet (3) being able to eat the right amount of food and (4) being able to manage food through proper planning, storing, preparing, and offering. With the above information extracted from the literature, it was determined, a serious enough problem existed to justify spending time, money and other resources to develop and implement an intervention. The theoretical framework supporting the development of the web portal is the social cognitive theory (SCT). In health promotion, the purpose of the SCT is to help people stay healthy through good self-management of health habits. This dissertation focused on four constructs: self-efficacy, behavioral capabilities, observational learning, and reinforcement to better understand how eating competence skills were enhanced and attrition rates lowered.

Wang, Sophie. "Optimizing rare variant association studies in theory and practice." Thesis, Harvard University, 2014. http://dissertations.umi.com/gsas.harvard:11430.
Full textAbstract:
Genome-wide association studies (GWAS) have greatly improved our understanding of the genetic basis of complex traits. However, there are two major limitations with GWAS. First, most common variants identified by GWAS individually or in combination explain only a small proportion of heritability. This raises the possibility that additional forms of genetic variation, such as rare variants, could contribute to the missing heritability. The second limitation is that GWAS typically cannot identify which genes are being affected by the associated variants. Examination of rare variants, especially those in coding regions of the genome, can help address these issues. Moreover, several studies have recently identified low-frequency variants at both known and novel loci associated with complex traits, suggesting that functionally significant rare variants exist in the human population.

Full textAbstract:
The growing literature dedicated to entrepreneurship has recently highlighted the importance of considering the founded firms’ exit not as an ending, negative stage in an entrepreneur’s work-life experience. Instead, the decision to leave one’s venture is a strategic choice undertaken for the firm’s sake or as a founding entrepreneur’s lifestyle choice and leading to various after-exit paths.
The thesis contributes to the stream of literature dedicated to the entrepreneurial exit and habitual entrepreneurship fields by (i) exploring the antecedents of the cross-road choice that founding entrepreneurs take right-after an acquisition occurs using a prospect theory approach and by (ii) investigating the characteristics that differentiate habitual founders from lifestyle entrepreneurs, borrowing from human capital theory and building on recent work in the field. From a methodological viewpoint, the thesis’ main contributions include (i) the use of a large dataset of 14,881 founders, created on the bases of the Crunchbase database (data.crunchbase.com), (ii) the focus on the very-after acquisition step taken by the founding entrepreneur and investigated in North America, Europe, and Asia, and (iii) the introduction of a relatively new unit of analysis -- habitual founders -- when discussing the characteristics of habitual entrepreneurship.
After introducing the thesis’ main concepts in Chapter 1, the various contributions are developed in the three following chapters. Chapter 2 offers a descriptive study of the current literature in the entrepreneurial exit field, with particular attention given to the individual voluntary choice of exiting the founded firm. Chapter 3 extends the previous study by focusing on the antecedents of the founder’s intention to leave or remain within the firm right after encountering its acquisition from external actors and investigating whether results hold across world regions. Chapter 4 centers the study on the differences leading entrepreneurs toward a lifestyle versus a multiple-ventures creation entrepreneurial approach. The Appendix offers a step-by-step explanation of the procedures undertaken to create the database; it is thought to be used by other researchers as a guideline toward the creation of a similar database.

Full textAbstract:
<p> While theoretical models of transgender identity development exist, theoretical models of post-transition social identity development are limited, and theoretical models of transgender individuals transitioning in later life are absent. As such, the purpose of this study is to explore the experience of transgender individuals coming out later in life, often after decades of hiding. Their experiences give voice to the trans community to define self-fulfillment as a transgender person post-transition. Additionally, this study explores the obstacles transgender elders navigate in middle and later life. </p><p> Using a semi-structured interview guide with 42 transgender elders 55 years and older, respondents constructed chronological narratives of their lived experiences. The data was analyzed using Charmaz’ (2004) Constructionist Grounded Theory method. The findings from this study support Breakwell’s (1986) Identity Process Theory (IPT) and explain how the study participants coped with threatened identities (Breakwell, 1983). </p><p> Additionally, the findings explain how Breakwell’s theory of identity integration and Amiot et al.’s (2007) theory of discrete stages of change lead to integrated social identities. The model that emerged in the findings expands the scope of social identity integration. The model I propose, Reflexive Authenticity, expands by adding an additional stage. Therefore, increasing to five stages of social identity development and implement action/interaction strategies with conditions and consequences at each stage. </p><p> Qualitative analysis of interview narratives revealed two distinct participant categories: Compartmentalized Social Identity and Integrated Social Identity. The essential difference between the two groups was participation in transgender advocacy or activism to support and mobilize the transgender community. This study sheds new light on the post-transition phase and the role that reflexive authenticity plays in transgender individuals’ integrated social identity. The theoretical implications suggest that political activity and commitment to building social and political acceptance of the transgender community are important facilitators of developing an integrated social identity. </p><p> The transgender elders in this study described early coping mechanisms they used to protect threatened core identities, the obstacles and barriers they faced along the way, and their journeys toward living authentically. These findings have important implications for the development of future research, policies, and interventions that support transgender individuals.</p>

Dulovits, Stephan, and Yonas Hadgu Tewelu. "New venture financing order and founder preference: A multi-case study of Austrian Tech startups." Thesis, Internationella Handelshögskolan, Jönköping University, IHH, Företagsekonomi, 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:hj:diva-48946.
Full textAbstract:
This study investigates the source of financing in Austrian tech startups and aims to identify the main factors that affect the decision making of these firms. In doing so, we aim to contribute to the relatively limited field of research conducted in Europe. In order to achieve the purpose of this study, we implemented a multiple case study method as the research design. For the purpose of this study, a literature review was used that generated a theoretical framework. This framework focuses on capital structure with the main emphasis being on the pecking order theory. Additionally, government financial support is included as a secondary priority. Together with the theoretical framework, our empirical findings i.e. data from the interviews with six companies, one email response, and two additional secondary data from an Austrian startup publication comprised the basis for our analysis. Our findings from the sample companies used in this study show that Austrian tech startups use internal funding as an initial source of financing their new venture. When it comes to the order of funding, our findings show that most of the startups used in this study utilized equity as a second source of financing after internal funding and before debt. However, when it comes to the preference of the founders, half preferred a financing order that is inline with the pecking order theory while the remaining half preferred otherwise choosing equity to debt. From this, three conclusions can be drawn. First, the limited funding options available affect the decision making and preference of the tech startups. Second, founders value the nonfinancial added value they can get from investors both when implementing and preferring a financing option. Third, the future growth potential and the long term strategy of the startups and their founders play a crucial role in the funding option they prefer to finance their venture. Additionally, when it comes to capital structure, we see that most Austrian tech startups used in this study do not have a set policy. When it comes to Government financial support (GFS), we see that financial support from the government plays a significant role in Austrian tech startup financing.

Gibson, Kimberly Dawn. "Lines by Someone Else: the Pragmatics of Apprompted Poems." Thesis, University of North Texas, 2015. https://digital.library.unt.edu/ark:/67531/metadc804948/.
Full textAbstract:
Over the last sixty years, overtly intertextual poems with titles such as “Poem Beginning with a Line by John Ashbery” and “Poem Ending with a Line by George W. Bush” have been appearing at an increasing rate in magazines and collections. These poems wed themselves to other texts and authors in distinct ways, inviting readers to engage with poems which are, themselves, in conversation with lines from elsewhere. These poems, which I refer to as “apprompted” poems, explicitly challenge readers to investigate the intertextual conversation, and in doing so, they adopt inherent risks. My thesis will chart the various effects these poems can have for readers and the consequences they may hold for the texts from which they borrow. Literary critics such as Harold Bloom and J. H. Miller have described the act of borrowing as competitive and parasitic—“agon” is Bloom’s term for what he sees as the oedipal anxiety of poets and poets’ texts to their antecedents, but an investigation of this emerging genre in terms of linguistic pragmatics shows that apprompted poems are performing a wider range of acts in relation to their predecessors. Unlike Bloom’s theory, which interprets the impulse of poetic creation through psychoanalysis, I employ linguistic terms from Brown and Levinson’s linguistic Politeness theory to analyze apprompted poems as conversational speech events. Politeness theory provides a useful analysis of these poems by documenting the weight of threats to the positive and negative “faces” of the participants in each poetic conversation. I have documented these “face-threatening-acts” and used them to divide apprompted poems into five major speech events: satire, revision, promotion, pastiche, and ecclesiastic. Ultimately, this paper serves at the intersection of literary criticism and linguistics, as I suggest a theoretical approach to the interpretation and criticism of apprompted poems by way of linguistic pragmatics.

Charles, S. R. "The emergent metaphysics in Plato's theory of disorder as found in The Timaeus and Laws X." Thesis, University of Edinburgh, 2003. http://hdl.handle.net/1842/4050.
Full textAbstract:
This thesis is an exploration of Plato’s understanding of the power of disorder as it is presented in his cosmology, The Timaeus and in his predominantly religious work, Laws X. In the former work this causal force is presented as the disordering power responsible for the physical chaos prior to the generation of the universe, as well as for any residual disorder found within the cosmos after it has been ordered and is the antithesis of ‘nous’ or reason. In the latter work, however, Laws X, the causal force for disorder is now understood as a disordering power capable of endangering the soul, active long after the cosmos has been generated and itself, a ‘Soul’. What ultimately emerges is a dynamic theory of disorder and a metaphysics supporting that theory, weaving through, connecting across and separating apart these two works. In Part I, consisting of five chapters, I provide the Greek, an original translation and commentary on seven key passages from The Timaeus where Plato presents his ideas on disorder, both as an effect within the cosmos and as a causal power or force for disorder prior to its generation. In this regard, I look closely at Plato’s use of the Greek word &V&YK~ in its role as a disordering power, but which has also been commonly understood and translated as ‘necessity’. I contrast this with Plato’s understanding of the role which the ‘Demiurge’ or the ordering power of the cosmos has played, with its faculty of ~06s or ‘reason’ and its access to ideal ‘Forms’ or ‘ideas’ when ordering or generating the universe. In Part 11, consisting of four chapters, Laws X is similarly presented, providing the Greek, a translation (for the most part, that of A. E. Taylor) and commentary on eight key passages. Here I investigate Plato’s understanding of disorder as it pertains specifically to the ‘soul’ and of the soul’s relation to the disordering power(s) and to ‘evil’. In the final chapter a theory of disorder is proposed, in which an epistemology is outlined, an ontology is given and from which, it is argued, a metaphysics of disorder emerges.

Murray, Jacqueline Ruth. "A visual analysis of HIV/AIDS antiretroviral therapy print campaign materials found in four Western Cape community clinic environments." Master's thesis, University of Cape Town, 2016. http://hdl.handle.net/11427/23426.
Full textAbstract:
Print media campaign material strongly influences people's perceptions of illness and health and the role and purpose of medication (NSMC, 2010: np). Because adherence is critical to the successful management of the Human Immunodeficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS), the introduction of antiretroviral treatment (ART) into the South African health sector presented a major communications challenge, namely how best to communicate awareness and administration of the drugs and how they should be taken. Over the past ten years, the government Department of Health (DoH), the Treatment Action Campaign (TAC), and other prominent nongovernmental HIV/AIDS organizations (NGOs) such as Love Life, Soul City and the Bishop Tutu Foundation have defined a number of different objectives aimed at the promotion of prescription generic antiretroviral drugs (Venter, 2014:3). This has led to an increase in the number of campaigns, each having singular visual representations of HIV/AIDS and users' relationships to antiretroviral drugs. Despite this, stigma and distrust around HIV/AIDS is prominent among the South African public (Rubincam, 2013:13). As a result, there remains a large amount of ambivalence toward the impact of ART on the body and its place within many communities. This has a direct bearing on issues of adherence. For this reason, it is important to study the nature and efficacy of the materials currently being used for social marketing in this context. This qualitative study therefore questions the nature of the current visual language of ART related leaflets and posters found in four Western Cape community clinics and asks whether the content effectively communicates an understanding of antiretroviral therapy, specifically around issues of adherence. In this study, I aim to identify ART adherence social marketing communication strategies used by leading NGOs and the DoH in South Africa. The nature of the visual and textual representations of antiretroviral print media campaign materials found in four Western Cape community clinic environments is established. The purpose of this research is to provide contemporary and useful information on the style, content, and design of social marketing materials in the hope that it will add significant value for further research on ART adherence. This study is a microanalysis focused on quality, not quantity. The investigation is modest. It does not consider a large sample and is intended as a starting point for further research. I hope to identify possible gaps between the combination of messages offered in leaflet and poster print media, and the needs of those infected with the virus, especially at a time when it necessitates they begin ART. The intended impact of this research is to encourage an increased understanding and awareness by government and NGO marketing departments of their campaign material so that it facilitates the transition onto treatment in a way that is empowering, informative, empathetic, and responsible.

Full textAbstract:
In industrial environments, operators are exposed to polluted air which after constant exposure can cause irreversible lethal diseases such as lung cancer. The current air monitoring techniques are carried out sparely in either a single day annually or at few measurement positions for a few days.In this thesis a theory-guided data science (TGDS) model is presented. This hybrid model combines a steady state Computational Fluid Dynamics (CFD) model with a machine learning model. Both the CFD model and the machine learning algorithm was developed in Matlab. The CFD model serves as a basis for the airflow whereas the machine learning model addresses dynamical features in the foundry. Measurements have previously been made at a foundry where five stationary sensors and one mobile robot were used for data acquisition. An Echo State Network was used as a supervised learning technique for airflow predictions at each robot measurement position and Gaussian Processes (GP) were used as a regression technique to form an Echo State Map (ESM). The stationary sensor data were used as input for the echo state network and the difference between the CFD and robot measurements were used as teacher signal which formed a dynamic correction map that was added to the steady state CFD. The proposed model utilizes the high spatio-temporal resolution of the echo state map whilst making use of the physical consistency of the CFD. The initial applications of the novel hybrid model proves that the best qualities of these two models could come together in symbiosis to give enhanced characterizations.The proposed model could have an important role for future characterization of airflow and more research on this and similar topics are encouraged to make sure we properly understand the potential of this novel model.<br>Industriarbetare utsätts för skadliga luftburna ämnen vilket över tid leder till högre prevalens för lungsjukdomar så som kronisk obstruktiv lungsjukdom, stendammslunga och lungcancer. De nuvarande luftmätningsmetoderna genomförs årligen under korta sessioner och ofta vid få selekterade platser i industrilokalen. I denna masteruppsats presenteras en teorivägledd datavetenskapsmodell (TGDS) som kombinerar en stationär beräkningsströmningsdynamik (CFD) modell med en dynamisk maskininlärningsmodell. Både CFD-modellen och maskininlärningsalgoritmen utvecklades i Matlab. Echo State Network (ESN) användes för att träna maskininlärningsmodellen och Gaussiska Processer (GP) används som regressionsteknik för att kartlägga luftflödet över hela industrilokalen. Att kombinera ESN med GP för att uppskatta luftflöden i stålverk genomfördes första gången 2016 och denna modell benämns Echo State Map (ESM). Nätverket använder data från fem stationära sensorer och tränades på differensen mellan CFD-modellen och mätningar genomfördes med en mobil robot på olika platser i industriområdet. Maskininlärningsmodellen modellerar således de dynamiska effekterna i industrilokalen som den stationära CFD-modellen inte tar hänsyn till. Den presenterade modellen uppvisar lika hög temporal och rumslig upplösning som echo state map medan den också återger fysikalisk konsistens som CFD-modellen. De initiala applikationerna för denna model påvisar att de främsta egenskaperna hos echo state map och CFD används i symbios för att ge förbättrad karakteriseringsförmåga. Den presenterade modellen kan spela en viktig roll för framtida karakterisering av luftflöden i industrilokaler och fler studier är nödvändiga innan full förståelse av denna model uppnås.

Gordon, Nicole R. "Cooking with Couples: A Grounded Theory Study on the Relational Aspects Found in the Cooking Interactions of Couples." Diss., NSUWorks, 2019. https://nsuworks.nova.edu/shss_dft_etd/46.
Full textAbstract:
Cooking is a universal activity which all humans can relate to on some level. Historically, cooking has continued to connect people across cultures and time, simultaneously providing nutritive sustenance as well as socio- and psychological benefits. Medical and mental health practitioners only in recent years have utilized cooking in a therapeutic process, and most of those cooking activities available tend to focus on cooking from an occupational and nutrition-education stance. A gap in the literature pertaining to cooking and its therapeutic applications exists around the relational nature underlying the cooking process, especially as it pertains to couples. While marriage and family therapists have used a number of creative experiential modalities in therapy for years, such as art and music therapy, cooking has been especially underutilized in comparison, despite its therapeutic and relational applicability. Therefore, this study was conducted to offer a foundation for understanding how the interactions in a kitchen can highlight relational elements between people.
Eight couples (16 participants) who have lived together for at least two years and who cook together often were interviewed in their homes. A constructivist grounded theory methodology was used for this study, and subsequent to data analysis, a three-part theory describing the relational components of couple’s cooking interactions emerged, called The Couple’s Cooking Triad. The theory is made up of Relationship Skills, Emotional Connections, and Languaging. Results from this study, organizing the complex interactions of couples in a kitchen, indicate further use by marriage and family therapists in an experiential therapeutic capacity.

Full textAbstract:
Increasing numbers of women are defying societal expectations and choosing not to have children. At the same time, their choices remain shrouded in disapproval and silence. Despite significant cultural changes and the influences of the feminist movement, the idea that womanhood equates with motherhood endures. The aims of this study were to critically understand why women choose not to have children and to consider the consequences of their choices on their lives. Twenty-two women aged between 40 and 75, from across England, Scotland, and Wales participated in this constructivist grounded theory study. All women were educated to degree level or higher and came from a range of social class backgrounds. Drawing from interviews with participants, this study presents three key findings to inform a sociological understanding of this topic. First, the findings reveal that participants’ choices not to have children are best understood as part of a complex interplay between restraining and liberating experiences in their lives. Social class also had a significant influence on their life experiences and subsequently on their choices. Their choices not to have children were formed within a specific social context and from the complex interplay of their personal and social experiences within an unequal world. Second, participants feel they are perceived as women of ‘lesser value’. This positioning is expressed through negative language, stereotyping, and reinforced in families, communities, and workplaces. This finding reveals the dominant societal gendered expectations that womanhood and motherhood are synonymous. It exposes a culture of silence, motherarchal ideas, and the societal practices that sustain it. Third, participants do not regret their choices. This finding challenges the myth that women who make this choice will experience regret and that motherhood and family is the only haven for fulfilment. This finding submits that a choice for non-motherhood is a choice for a different life that offers multiple possibilities. Taken together, the findings support previous and current research. They also raise important issues and questions for further study. More research and work is needed to ensure that women’s choices for non-motherhood are understood, respected, and supported. Moreover, it will be necessary to understand and challenge the dominant pronatalist ideas that denigrate alternative choices.

Full textAbstract:
Many are beginning to see the promise that the quantum world has offered those who manage and lead organizations (Wheatley, 1992; Zohar, 1997). The Newtonian world is one in which all "things" are reduced to their smallest parts, separated, divided, and analyzed with predictability, with complete control being the ultimate goal. The quantum world is one of infinite possibilities, infinite fields of influence, and infinite relationships. The hallmark characteristics found in a manager who has been schooled in the quantum sciences are flexibility, responsiveness, synchronicity, serendipity, creativity, innovation, participation, and motivation. In a quantum organization there is the constant awareness of the whole system, but there is also diversity (wave or particle), which allows for self-organization that is based on the environment and its requirements. In the quantum world many paths lead from A to Z, and depending on the path chosen, numerous realities wait to unfold. It was the goal of this research to explore the changing of leader behaviors through exposure to the models and theories found in quantum physics. From a quantum perspective this behavior change is possible; the only question is the readiness, willingness, and ability of the leaders to allow their behaviors to be surfaced and challenged. These are indeed the greatest challenges for all people as they proceed through life and work - readiness for change, willingness to change, and ability to surface key areas where change is needed.

Full textAbstract:
The first part of this thesis articulates and defends the Subjectivist View of the Mental. According to this view, my mental states are essentially different from the mental states of everyone else, but the fact that they are is a subjective fact, rather than an objective one. Chapter 1 explains what it takes for a fact to be subjective, what kind of difference holds between my mental states and everyone else's mental states and what kind of intuitions lead me to believe that there is such a difference. Chapter 2 defends the Subjectivist View of the Mental from objections and discusses some of its most significant implications. In the second part of the thesis, I explore the advantages that the Subjectivist View of the Mental offers when it comes to accounting for three basic features of our knowledge of the mental. Chapter 3 deals with the asymmetry between self-knowledge and knowledge of other minds. It is argued that, if the Subjectivist View of the Mental is true, we can explain why this asymmetry holds without assuming that self-knowledge and knowledge of other minds are involved with substantially different ways of knowing. Chapter 4 focuses on the immunity to error through misidentification of mental self-ascriptions. I show that, while there has been a temptation to explain this phenomenon by following Lichtenberg and Wittgenstein in taking the content of mental self-ascriptions to be general rather than particular, this proposal cannot be made to work unless something like the Subjectivist View of the Mental is true. Chapter 5 is concerned with experiential knowledge. I argue that, if experiential truths are taken to be objective truths, it is not easy to see why experiential knowledge should have the peculiar 'first-hand' character it has. The problem disappears if experiential truths are regarded as subjective rather than objective.<br>La primera parte de esta tesis articula y defiende la Teoría Subjetivista de lo Mental. Según esta teoría, mis estados mentales son esencialmente diferentes de los estados mentales de los demás, pero el hecho de que lo son no es un hecho objetivo, sino que un hecho subjetivo. El Capítulo 1 explica qué significa que un hecho sea subjetivo, qué tipo de diferencia hay entre mis estados mentales y los estados mentales de los demás y qué tipo de intuiciones me llevan a creer que haya esta diferencia. El Capítulo 2 defiende la Teoría Subjetivista de lo Mental frente a objeciones y discute algunas de sus implicaciones más importantes. En la segunda parte de la tesis, voy a examinar las ventajas que la Teoría Subjetivista de lo Mental ofrece cuando se trata de dar cuenta de tres fenómenos característicos de nuestro conocimiento de los hechos mentales. El Capítulo 3 trata de la asimetría entre el conocimiento de nuestra propia mente y el conocimiento de otras mentes. Se argumenta que, si la Teoría Subjetivista de lo Mental es correcta, es posible explicar esta asimetría sin asumir que el conocimiento de nuestra propia mente y el conocimiento de otras mentes están basados en diferentes formas de conocimiento. El Capítulo 4 se centra en la “inmunidad al error mediante identificación equivocada” de las auto-atribuciones mentales. Lo que voy a mostrar es que, aunque haya habido una tendencia a explicar este fenómeno diciendo (como Lichtenberg y Wittgenstein) que el contenido de la auto-atribuciones mentales es general y no particular, esta estrategia no puede funcionar a menos que la Teoría Subjetivista de lo Mental sea correcta. El Capítulo 5 se ocupa del conocimiento experiencial. Se argumenta que, si las verdades experienciales son consideradas como verdades objetivas, es difícil explicar porqué el conocimiento experiencial tiene que ser conocimiento de 'primera mano'. El problema desaparece si las verdades experienciales son consideradas como verdades subjetivas.

Full textAbstract:
There is a high failure rate among local community-based nonprofit human service organizations in New York State, which may lead to service gaps in communities. Increasing sustainability may reduce these gaps and allow nonprofits to continue following the first leadership transition. Using McGregor's human resource theory as the guide, the purpose of this phenomenological study was to explore the relationship between leadership succession planning and how departure of founding leaders impacts the sustainability of nonprofits. Data were collected through interviews with 16 leaders that included departing founding leaders, successors, and 2 board members in 4 local community-based nonprofit human service organizations in New York State, regarding the impact of the founder's departure on (a) leadership, (b) motivation, (c) teamwork, (d) power balance, (e) work environment, and (f) organizational change. Interview data were inductively coded and analyzed using a thematic analysis procedure. The results yielded 4 thematic elements that contributed to successful outcomes: (a) strengthening accountability to balance power, (b) individual versus collaborative leadership to increase shared governance, (c) assessing and developing competencies to efficiently use human resources, and (d) ability to conceptualize change and plan for the future. The results of this research study may help to contribute to positive social change by offering the leaders of local community-based nonprofit human service organizations strategies to sustain their organizational culture during and following their first leadership transition, involving the departure of the founder, allowing the organizations to continue to contribute positively to the community.

Full textAbstract:
Regulatory Focus Theory predicts that the motivation to self-regulate goal-directed thought and behavior depends on two distinct regulation strategies: a promotion focus based on attaining gains and a prevention focus based on avoiding losses.
This study took a social-cognitive approach predicting that regulatory focus has an impact on how family startups (several family related founders) explore “new ideas”, exploit “old certainties” and achieve the balance of both (ambidexterity), compared to lone founder startups (only one founder present).
It was proposed that the social context of family ties among founders leads them to a prevention focus concerned with avoiding the loss of the socio-emotional benefits of those ties. In order to avoid such a loss, family founders were expected to increase their risk perceptions and thus, explore less than lone founders, who lack such socio-emotional ties. It was also proposed that two commonly used psychological traits in entrepreneurship research --achievement motivation and internal locus of control, predispose entrepreneurs to a promotion focus. Founders with a promotion focus, in turn, were hypothesized to lead startups to more risk-seeking behaviors and to more explorative orientation.
The previous argument was used as a springboard to derive hypotheses about ambidexterity (the ability to exploit and explore simultaneously) and survival hazards. Using Regulatory Focus Theory, exploitative orientation, conceptualized as the motivational strength to continue on previous paths of action, was hypothesized to be not significantly different from that of lone founder startups. Taking previous arguments together, lone founder startups were hypothesized to be more ambidextrous than family startups. Finally, ambidexterity and internal locus of control were hypothesized to reduce survival hazards in family startups.
The findings suggested that family startups explore less than lone founder startups even after controlling for group effects. Interesting but contradictory findings revealed that internal locus of control have both a positive direct effect and a positive interaction that increases the explorative and ambidextrous orientation gap of family startups over lone founder startups. As expected, ambidexterity and internal locus of control reduced survival hazards on family startups. Implications for practitioners were derived based on a sample of 470 nascent entrepreneurs.

Full textAbstract:
Abstract The rapid development of digital technology and software in recent years has created great variety of totally new business opportunities. Software startups are commonly considered to be the fastest in exploiting the new opportunities and the most innovative in creating new products and services. At the same time, software startups are often small, immature enterprises with limited resources and inexperienced teams. The initial team plays a key role in the early stages of a software startup. This research focuses on the initial team from the perspective of human capital – the knowledge, experiences, skills, and other cognitive abilities. It studies the initial team empirically, utilizing the multi-case study and triangulation methods applying the human capital, resource-based view, capability, and the opportunity discovery and creation theories. The empirical data were gathered from thirteen software startups in Italy, Norway and Finland, and from a student experiment. From the analysis of this data, a generic structure of a software startup’s initial team was identified, consisting of three different roles, with each having a specific human capital profile. This team structure sought a balance between the team’s human capital and problems and challenges to be solved. The level of the initial human capital of the team and the means to strengthen it varied, and affected the progress of the work in the studied startups. Though the components of the team’s human capital were not rare and inimitable in terms of the resource-based view, building a balanced startup team created a unique and task-specific setup, which is a key capability of a software startup. The balanced startup team structure is proposed to be the generic human capital model of a software startup’s initial team<br>Tiivistelmä Digitaalitekniikan ja ohjelmistojen nopea kehitys viime vuosina on synnyttänyt suuren joukon kokonaan uusia liiketoimintamahdollisuuksia.

Samples were examined in both short andextended periods of contact (5 and 20 min) with liquid casting. Castingsolidification was extended in order to intensify the corrosion effects. Contraryto common findings, it was found that the ejection force of the investigatedmaterials does not depend on their chemical composition. For the coatedsamples, a pronounced dependence of the ejection force on the surfaceroughness was found. The ejection force increases with decrease in surfaceroughness. All investigated coatings are prone to mechanical soldering by Al–Si–Cu alloy. Still, their corrosion resistance substantially exceeds the corrosionresistance of steel and plasma nitrided layer. Longer exposure of coatedsamples to cast alloy induced lower ejection forces, which is a consequenceof coatings oxidation. It was found that the investigated coatings are inert toliquid aluminium. However, the underlying material undergoes oxidation andcorrosion through coating growth defects. The findings concerning the wearmechanisms of protective layers support further development of duplex layersintended for die casting tools protection.

Introducción. El objetivo del presente estudio es determinar si existe correlación entre los conocimientos sobre las consecuencias de la obesidad y el grado de actividad física de las personas.
Métodos. Se realizó un estudio transversal analítico durante los años 2013 y 2014. Participaron 215 alumnos de pregrado seleccionados por conveniencia no relacionados a carreras del campo de la salud en una universidad de Lima, Perú. Se evaluó el grado de actividad física utilizando el International Physical Activity Questionnaire (IPAQ) y el nivel de conocimientos sobre consecuencias de la obesidad utilizando la escala Obesity Risk Knowledge-10 (ORK-10). También, se consignó las fuentes de información de donde obtuvieron el conocimiento para responder dicho cuestionario.
Resultados. La mediana de edad fue 20 (rango intercuartílico=4) y 63% eran mujeres. De acuerdo al IPAQ, 53,9% realizaban actividad física alta, 35,4%, moderada y 10,7%, leve. Se encontró una correlación muy baja (rs=0,06) entre el puntaje del ORK-10 y la cantidad de equivalentes metabólicos/minuto consumidos por semana, pero no era significativa (p=0,38). Las personas informadas por medios de comunicación y por personal de salud obtuvieron mayores puntajes en el ORK- 10 que quienes se informaron por otras vías (p<0,05).
Conclusiones. La correlación entre los conocimientos sobre consecuencias de la obesidad y el grado de actividad física es muy baja. Es necesario utilizar enfoques
multidisciplinarios que incluyan todos los determinantes de la realización de actividad física para poder lograr cambios en la conducta de la población.

La present tesi doctoral s’ha centrat en el repte d’aconseguir, mitjançant Fabricació Additiva (FA), models per a assaig quirúrgic, sota la premissa que els equips per fer-los haurien de ser accessibles a l’àmbit hospitalari. L’objectiu és facilitar l’extensió de l’ús dels prototips com a eina de preparació d’operacions quirúrgiques, transformant la pràctica mèdica actual de la mateixa manera que en el seu moment ho van fer tecnologies com les que van facilitar l’ús de radiografies. El motiu d’utilitzar FA, en lloc de tecnologies més tradicionals, és la seva capacitat de materialitzar de forma directa les dades digitals obtingudes de l’anatomia del pacient mitjançant sistemes d’escanejat tridimensional, fent possible l’obtenció de models personalitzats. Els resultats es centren en la generació de nou coneixement sobre com aconseguir equipaments d’impressió 3D multimaterials accessibles que permetin l’obtenció de models mimètics respecte als teixits vius. Per facilitar aquesta buscada extensió de la tecnologia, s’ha focalitzat en les tecnologies de codi obert com la Fabricació per Filament Fos (FFF) i similars basades en líquids catalitzables. La recerca s’alinea dins l’activitat de desenvolupament de la FA al CIM UPC, i en aquest àmbit concret amb la col·laboració amb l’Hospital Sant Joan de Déu de Barcelona (HSJD). El primer bloc de la tesi inclou la descripció de l’estat de l’art, detallant les tecnologies existents i la seva aplicació a l’entorn mèdic. S’han establert per primer cop unes bases de caracterització dels teixits vius -sobretot tous- per donar suport a la selecció de materials que els puguin mimetitzar en un procés de FA, a efectes de millorar l’experiència d’assaig dels cirurgians. El caràcter rígid dels materials majoritàriament usats en impressió 3D els fa poc útils per simular tumors i altres referències anatòmiques. De forma successiva, es tracten paràmetres com la densitat, la viscoelasticitat, la caracterització dels materials tous a la indústria, l’estudi del mòdul elàstic de teixits tous i vasos, la duresa d’aquests, i requeriments com l’esterilització dels models. El segon bloc comença explorant la impressió 3D mitjançant FFF. Es classifiquen les variants del procés des del punt de vista de la multimaterialitat, essencial per fer models d’assaig quirúrgic, diferenciant entre solucions multibroquet i de barreja al capçal. S’ha inclòs l’estudi de materials (filaments i líquids) que serien més útils per mimetitzar teixits tous. Es constata com en els líquids, en comparació amb els filaments, la complexitat del treball en processos de FA és més elevada, i es determinen formes d’imprimir materials molt tous. Per acabar, s’exposen sis casos reals de col·laboració amb l’HJSD, una selecció d’aquells en els que el doctorand ha intervingut en els darrers anys. L’origen es troba en la dificultat de l’abordatge d’operacions de resecció de tumors infantils com el neuroblastoma, i a la iniciativa del Dr. Lucas Krauel. Finalment, el Bloc 3 té per objecte explorar nombrosos conceptes (fins a 8), activitat completada al llarg dels darrers cinc anys amb el suport dels mitjans del CIM UPC i de l’activitat associada a treballs finals d’estudis d’estudiants de la UPC, arribant-se a materialitzar equipaments experimentals per validar-los. La recerca ampla i sistemàtica al respecte fa que s’estigui més a prop de disposar d’una solució d’impressió 3D multimaterial de sobretaula. Es determina que la millor via de progrés és la de disposar d’una pluralitat de capçals independents a fi de capacitar la impressora 3D per integrar diversos conceptes estudiats, materialitzant-se una possible solució.

La investigación amplia y sistemática al respecto hace que se esté más cerca de disponer de una solución de impresión 3D multimaterial de sobremesa. Se determina que la mejor vía de progreso es la de disponer de una pluralidad de cabezales independientes, a fin de capacitar la impresora 3D para integrar diversos conceptos estudiados, materializándose una posible solución.

Full textAbstract:
Multi functional health monitoring wearable devices are quite prominent these days. Usually these devices are battery-operated and consequently are limited by their battery life (from few hours to a few weeks depending on the application). Of late, it was realized that these devices, which are currently being operated at fixed voltage and frequency, are capable of operating at multiple voltages and frequencies. By switching these voltages and frequencies to lower values based upon power requirements, these devices can achieve tremendous benefits in the form of energy savings. Dynamic Voltage and Frequency Scaling (DVFS) techniques have proven to be handy in this situation for an efficient trade-off between energy and timely behavior. Within imec, wearable devices make use of the indigenously developed MUSEIC v2 (Multi Sensor Integrated circuit version 2.0). This system is optimized for efficient and accurate collection, processing, and transfer of data from multiple (health) sensors. MUSEIC v2 has limited means in controlling the voltage and frequency dynamically. In this thesis we explore how traditional DVFS techniques can be applied to the MUSEIC v2. Experiments were conducted to find out the optimum power modes to efficiently operate and also to scale up-down the supply voltage and frequency. Considering the overhead caused when switching voltage and frequency, transition analysis was also done. Real-time and non real-time benchmarks were implemented based on these techniques and their performance results were obtained and analyzed. In this process, several state of the art scheduling algorithms and scaling techniques were reviewed in identifying a suitable technique. Using our proposed scaling technique implementation, we have achieved 86.95% power reduction in average, in contrast to the conventional way of the MUSEIC v2 chip’s processor operating at a fixed voltage and frequency. Techniques that include light sleep and deep sleep mode were also studied and implemented, which tested the system’s capability in accommodating Dynamic Power Management (DPM) techniques that can achieve greater benefits. A novel approach for implementing the deep sleep mechanism was also proposed and found that it can obtain up to 71.54% power savings, when compared to a traditional way of executing deep sleep mode.<br>Nuförtiden så har multifunktionella bärbara hälsoenheter fått en betydande roll. Dessa enheter drivs vanligtvis av batterier och är därför begränsade av batteritiden (från ett par timmar till ett par veckor beroende på tillämpningen). På senaste tiden har det framkommit att dessa enheter som används vid en fast spänning och frekvens kan användas vid flera spänningar och frekvenser. Genom att byta till lägre spänning och frekvens på grund av effektbehov så kan enheterna få enorma fördelar när det kommer till energibesparing. Dynamisk skalning av spänning och frekvens-tekniker (såkallad Dynamic Voltage and Frequency Scaling, DVFS) har visat sig vara användbara i detta sammanhang för en effektiv avvägning mellan energi och beteende. Hos Imec så använder sig bärbara enheter av den internt utvecklade MUSEIC v2 (Multi Sensor Integrated circuit version 2.0). Systemet är optimerat för effektiv och korrekt insamling, bearbetning och överföring av data från flera (hälso) sensorer. MUSEIC v2 har begränsad möjlighet att styra spänningen och frekvensen dynamiskt. I detta examensarbete undersöker vi hur traditionella DVFS-tekniker kan appliceras på MUSEIC v2. Experiment utfördes för att ta reda på de optimala effektlägena och för att effektivt kunna styra och även skala upp matningsspänningen och frekvensen. Eftersom att ”overhead” skapades vid växling av spänning och frekvens gjordes också en övergångsanalys. Realtidsoch icke-realtidskalkyler genomfördes baserat på dessa tekniker och resultaten sammanställdes och analyserades. I denna process granskades flera toppmoderna schemaläggningsalgoritmer och skalningstekniker för att hitta en lämplig teknik. Genom att använda vår föreslagna skalningsteknikimplementering har vi uppnått 86,95% effektreduktion i jämförelse med det konventionella sättet att MUSEIC v2-chipets processor arbetar med en fast spänning och frekvens. Tekniker som inkluderar lätt sömn och djupt sömnläge studerades och implementerades, vilket testade systemets förmåga att tillgodose DPM-tekniker (Dynamic Power Management) som kan uppnå ännu större fördelar. En ny metod för att genomföra den djupa sömnmekanismen föreslogs också och enligt erhållna resultat så kan den ge upp till 71,54% lägre energiförbrukning jämfört med det traditionella sättet att implementera djupt sömnläge.

In this thesis I outline my theory of translation as an interpretive tool. I undertake an analysis of the concepts of heteroglossia, hybridity, and positionality, as conceived of by Mikhail Bakhtin, Homi K. Bhabha, and Linda Alcoff, respectively. These ideas function similarly: heteroglossic forces are constantly being brought to bear upon languages, the hybrid nature of culture is continually being rearticulated, and the positionality of the interpreter is always subject to change. I establish a theory that allows for translation to remain open, a theory that sees all incarnations of a text (the source and all of its translations) as being perpetually discursive, rather than fixing upon one version as the definitive or “correct” rendering. Translations occupy a fluctuating, unstable, and therefore creative location; they provide an ever-shifting temporal and spatial perspective. I translate excerpts from texts written by the Afro-German poet May Ayim and the Turkish German author Emine Sevgi Özdamar from German into English. This brings my theory into application and demonstrates both the fluidity of translation and the depth of interpretation to be found within this process.<br>Graduate<br>0311<br>0679

Full textAbstract:
This thesis paper explores some of the cultural phenomena that influence my conceptual framework and describes the logic behind the formal decision-making that defines my work. Beginning with a description of the nature of the materials and environments I appropriate, this thesis aims to deconstruct the layered system of binaries that build the logic behind my work. The concerns in my work circulate around domestic consumption and the objects detritus, a term coined in the paper, that are produced as a result. However, rather than allow the objects detritus to remain cast-aways of a culture of excess, my work reincorporates these objects as materials in conglomerate sculptures. This thesis depicts the complex of ideas that help delegate how these conglomerate works come into being.

The motivation for this study is the increase of treatment needs of heroin dependents at SANCA, (South African National Council of Alcohol and Drug Abuse) Witbank. SANCA Witbank wants to ensure that the most effective treatment can be supplied.
Research goals are to:
 Do a literature study of out-patient treatment programmes.
 Assess the needs of heroin out-patient dependents with regard to out-patient treatment programmes.
 Make recommendations with regard to out-patient treatment programmes for heroin dependents.
It was an exploratory research subject and the data collection methods were qualitative and quantitative. Interview schedules were used as research tools. Schedule B was completed by the researcher with heroin dependents that visited SANCA Witbank for the period 31 January 2005 to 4 February 2005. Schedule A was completed by the researcher with personnel of SANCA out-patient clinics and the questions were discussed and completed telephonically.
The conclusion is that the treatment programme of SANCA Witbank is in line with the rest of the drug dependent field and only minimal recommendations were made.<br>Social Work<br>MA(SS)(MENTAL HEALTH)

Tese de doutoramento em Sociologia, apresentada à Faculdade de Economia da Universidade de Coimbra<br>A presente tese consiste em um estudo sociológico a partir do caso da Usina
Hidroelétrica Belo Monte, em construção no Estado do Pará, na Amazônia brasileira. O
objetivo deste estudo foi dedicar um olhar para a questão da saúde a partir da perspectiva
das populações atingidas pelo megaprojeto hidroelétrico. O trabalho inicia com uma
apresentação do histórico dos projetos de barramento do rio Xingu, em meados dos anos
1970. Dos primeiros estudos da bacia hidrográfica do Xingu até o início da obra de Belo
Monte passaram-se aproximadamente trinta anos e, durante esse período, muitas
polémicas e disputas envolveram as populações atingidas, políticos, intelectuais, artistas,
cientistas, ativistas e movimentos sociais. Também é discutido nesta tese o modelo de
desenvolvimento económico brasileiro, para se compreender como se dá a opção pela
construção de grandes projetos de infraestrutura, como é o caso de Belo Monte. A partir
dessa primeira abordagem ao megaprojeto, passo a dar ênfase à perspectiva das
populações atingidas por Belo Monte. Para tanto, foi necessário, primeiramente, conhecer
melhor o universo de populações atingidas, compostas por populações urbanas, rurais,
comunidades ribeirinhas e indígenas. Através do trabalho empírico realizado em
Brasília/DF e Altamira/PA, foi possível conhecer e reconhecer a diversidade dessas
populações e, assim identificar algumas questões importantes que não foram objeto de
debate com o poder público e o empreendedor. É o que Boaventura de Sousa Santos
(2006) chama de produções de não existência, ou invisibilidades. A utilização da matriz
teórica das epistemologias do Sul (Santos, 2002) permitiu o reconhecimento dessas
invisibilidades, isto é, permitiu ver como as alterações no ambiente e nos modos de vidas
das populações atingidas por Belo Monte afetam a saúde e a qualidade de vida destas. É
a partir dessa lente que se dedica o olhar para a saúde das populações atingidas, e a
problematização dessa questão é realizada nesta tese tendo como protagonistas as
próprias populações atingidas. Assim foi identificado como um dos problemas relevantes
decorrentes da construção da Usina Hidroelétrica Belo Monte a relação entre o sofrimento
sentido pelas populações atingidas e o surgimento de agravos à saúde. O sofrimento
difuso é um conceito desenvolvido por Valla (2001) que será discutido nesta tese na
medida em que é constatado como uma consequência de Belo Monte invisibilizada. Isto
porque não foi previsto ou discutido como uma possibilidade, nem no Estudo de Impacto Ambiental (EIA), nem no seu respectivo Relatório de Impacto Ambiental (Rima).
Também não foi percebido como uma situação merecedora de atenção por parte do órgão
fiscalizador responsável pela conceção das licenças que permitiram Belo Monte ser
construída, o Ibama. Ainda, a relação entre o sofrimento e os agravos à saúde das
populações atingidas não foi alvo de políticas públicas na área da saúde pública. Dessa
forma, pretende este trabalho contribuir para a discussão sobre a saúde das populações
atingidas pelo megaprojeto Belo Monte, a partir do reconhecimento das populações
atingidas como detentoras e produtoras de conhecimento relevante.
~This thesis consists of a sociological study from the case of Belo Monte
Hydroelectric Power Plant, under construction in the State of Pará, in the Brazilian
Amazon. The aim of this study was to dedicate a look at the issue of health from the
perspective of the people affected by hydroelectric megaproject. The work begins with a
presentation of the history of the Xingu River dam projects in the mid-1970s From the
first studies of the watershed of the Xingu to the early work of Belo Monte it took about
thirty years and during this period, many controversies and disputes involving the
populations concerned, politicians, intellectuals, artists, scientists, activists and social
movements. It is also discussed in this thesis the Brazilian model of economic
development, to understand how is the option for the construction of large infrastructure
projects, such as the case of Belo Monte. From this first approach to megaproject, then I
give emphasis to the perspective of populations affected by Belo Monte. Therefore, it was
necessary, firstly, to know the universe of affected populations, composed of urban, rural
populations, coastal communities and indigenous people. Through the empirical work
done in Brasilia / DF and Altamira / PA, it was possible to know and recognize the
diversity of these populations and thus identify some important issues that were not
subject to discussion with the government and the entrepreneur. It's what Boaventura de
Sousa Santos (2006) calls invisibilities. Using the theoretical framework of South
epistemologies (Santos, 2002) allowed the recognition of these invisibilities, allowed to
see how changes in the environment and ways of life of the populations affected by Belo
Monte affect the health and quality of life of that people. It is from this lens that is
dedicated to looking at the health of the populations, and the questioning of this issue is
carried out in this thesis having as protagonists the affected populations themselves. Thus
it was identified as one of the relevant issues arising from the construction of the Belo
Monte Hydroelectric Plant the relationship between the suffering experienced by the
affected populations and the emergence of health problems. The diffuse suffering is a
concept developed by Valla (2001) which will be discussed in this thesis since it is found
as a result of Belo Monte. This is because it was not planned or discussed as a possibility,
or the Environmental Impact Study (EIA), or in their respective Environmental Impact
Report (RIMA). It was also not perceived as a worthy position of attention by the supervisory body responsible for the design of the licenses that allowed Belo Monte is
built, the Ibama. Also, the relationship between suffering and health problems of the
affected population was not the target of public policies in the field of public health. Thus,
this work aims to contribute to the discussion on the health of populations affected by
Belo Monte mega-project, from the recognition of the people affected as having relevant
knowledge.<br>Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) - Nº BEX 1749-13-7
