[pt] Este trabalho teve como objetivo propor um sistema construtivo misto eficiente e econômico para edificações. Foram concebidos dois detalhes de ligação semi-rígida mista, o primeiro para colunas de extremidade, e o segundo para colunas intermediárias, executados no eixo de maior inércia da coluna. A ligação de extremidade motivou o desenvolvimento de um novo elemento de ligação: o conector T-rib. Sua principal função é transmitir a resultante das barras de armadura de flexão nas regiões de momento negativo para a mesa das colunas de extremidade. O presente trabalho também envolveu uma investigação de dois modelos para ligações semi-rígidas: o modelo analítico simplificado de Kishi-Chen, [CHEN93], e o modelo mecânico do Anexo J do EUROCODE3, [EURO98], gerando duas alternativas para modelos semi-rígidos mistos. O primeiro modelo de cálculo, desenvolvido a partir do modelo de Kishi e Chen, [CHEN93], permite o cálculo dos dois detalhes de ligação citados anteriormente. O segundo modelo proposto foi concebido a partir da incorporação das contribuições do conector T-rib, das cantoneiras de alma e das barras de armadura existentes nos dois detalhes de ligação citados anteriormente, já que o modelo original do EUROCODE3, não considera estas componentes. Uma calibração dos modelos propostos foi executada a partir de uma comparação com valores obtidos experimentalmente no presente trabalho. Uma solução alternativa para conectores de cisalhamento de vigas mistas de concreto e aço também foi desenvolvida. Esta solução consistiu na adaptação do conector de cisalhamento perfobond rib utilizado em pontes mistas para uso em edificações correntes. Esta investigação resultou na criação de um novo layout para este tipo de ensaio. Este novo ensaio permitiu a determinar a contribuição dos cilindros de concreto e barras de armadura nos furos do conector perfobond rib e aferiu, pela primeira vez na literatura, a fórmula de resistência ao cisalhamento para este conector proposta por Oguejiofor e Hosain, [OGUE94]. Para caracterizar os possíveis estados de ruína do conector T-rib uma série de seis ensaios foi executada. Esta etapa de trabalho compreendeu o desenvolvimento de um novo tipo de ensaio de arrancamento projetado especialmente para esta investigação. Para avaliar o desempenho global do sistema construtivo proposto foi construído e ensaiado um pórtico plano semi-rígido misto em escala real, executado de modo a permitir a aferição do comportamento real das ligações, do comportamento do conjunto das viga-mistas e das vigas- colunas da estrutura. Este ensaio permitiu a determinação de curva carga versus. Rotação, uma estimativa dos esforços máximos de flexão nas ligações, etc. / [en] This work focused on the development of an efficient and economic composite building system. This was accomplished by the conception of two new composite major axis connection details for external and intermediate columns. The external column connection detail motivated the creation of a new connection element: the T-rib connector. The main purpose of this element is to transmit the reinforcement bars forces directly to the external columns in negative moment regions The present study also comprehended an nvestigation of two semi-rigid connections design models:the simplified analytical model of Kishi-Chen, [CHEN93], and the Eurocode 3 mechanical model,[EURO98], leading to further developments in both structural models. The first proposal extends the Kishi-Chen model, [CHEN93], for the external and intermediate columns connections investigated in this work. The second proposal incorporated the contributions of the T-rib connector, the web angles and the reinforcement bars on the EUROCODE3 model, since they were not originally taken into account. Both model were calibrated against the experimental results produced in the present investigation. An alternative solution for composite beams shear connectors was also developed. This solution consisted of an adaptation of the perfobond rib shear connector, generally used in composite bridges, to residential or commercial building construction. This investigation resulted in the development of a new test layout for the required experiments. These experiments enabled the determination of the individual contribution of the concrete dowels and reinforcement bars used in the perfobond rib connector holes. As far as it is known, these tests enable the calibration and evaluation V of each individual term of the perfobond rib resistance formula proposed by Oguejiofor and Hosain, [OGUE94]. A set of six tests was also made to characterise the T-Rib connector ultimate limit states. This procedure also required the development of a new pullout test procedure and layout especially designed for this purpose. To evaluate the global performance of the proposed building system a full-scale composite semi-rigid portal frame was built and tested up to collapse. The experimental programme provided information on real structural behaviour where the influence of connections, beam as beam column behaviour ads second order efectswere full investigated. This experimental research enabled the determination of: load versus rotation curves, an estimation of the maximum connection s bending forces, etc. / [es] Este trabajo tiene como objetivo proponer un sistema constructivo mixto eficiente y económico para edificaciones.

Thesis advisor: Micah Lott / How do we rectify structural injustice? Iris Marion Young presents a Social Connection Model that states those who participate in social processes that produce injustice have a forward-looking responsibility to redress the resulting injustice. Within some philosophical discourse, however, there is a general consensus that SCM is not action-guiding and is overly demanding. To supplement Young’s ideas, I explore Robin Zheng’s Role-Ideal Model; Zheng fills some necessary gaps left by Young. My aim in this paper is to use Young's SCM and Zheng's RIM in tandem to create a more action-guiding and ameliorative project for structural injustice. I offer a structurally sensitive account of responsibility for disempowerment that avoids passively repeating domination. I establish a prefatory set of tasks that can be applied to all roles. These tasks are an expansion of the terms mentioned in Zheng Role-Ideal:“raised consciousness” and “boundary pushing.” / Thesis (BA) — Boston College, 2022. / Submitted to: Boston College.

This master theses depicts FEM analysis of bolt joints where the focus is on investigating the stressrelationship between plate and bolt. Two bolts, M8 and M16, have been analyzed where they havebeen prestressed to 70 % of the ultimate tensile strength for steel type 8.8. A surface load has beenapplied in tension along the lateral surface of a cylindrical plate. The load distribution between plateand bolt of the external load varies between 2-28 % and 1-99 % for M8 and M16 in comparison to 20% stated in equation 2.7 in SS-EN 1993-1-8.The conclusion of studies shows that the behavior between the bolt and plate is not as previouslythought in SS-EN 1993-1-8. The bolt deforms negatively first when the system is subjected to externalload. This causes the resulting force to decrease. This behavior means that the bolt is designed towithstand larger loads than necessary. The factor 0.2 should be redefined. The authors recommendthat methods proposed by Pedersen and Pedersen [2008] or Haidar et al. [2011] should be used.

Misinterpretations of William James' pragmatic account of truth are due to three main factors. First, the failure to see the connection between James' account of truth and his account of reality (that is, the connection between pragmatism and radical empiricism). Second, the failure to see James' philosophical project as essentially involving the reinterpretation of traditional philosophical concepts. Third, the mistaken belief that pragmatism provides a formula or rule for determining the truth or falsity of beliefs. In this thesis, these three factors provided a framework for my own interpretation of James' account of truth. In the introduction, I briefly discuss the connection between pragmatism and radical empiricism. In the first chapter, I show that philosophical notions like 'consciousness', 'perception', 'subjectivity' and 'objectivity' are reinterpreted in James' account of reality. In the second chapter, I show how his reinterpretations of 'correspondence', 'coherence', and 'utility' lead to what is better called an 'account' of truth instead of a 'theory' of truth. The third chapter provides further elaboration on his account of truth by examining conceptual systems and 'necessary' truths. In the conclusion, I examine the emphasis which separates James' pragmatic account of truth from other versions, namely, the emphasis on individual experience in determining and constituting truth. / Thesis / Master of Arts (MA)

In the first chapter of this thesis it is shown that Hume has not denied a "real connection" between physical causes and effects. It is argued that Hume is not mainly concerned with the ontological status of causal necessity. His main contention is epistemological; he aims to explain the grounds we have for asserting causal connections. When we look for the grounds of casual interference we find nothing but constant conjunction, which accounts for the mental determination to pass from an impression to the idea of its usual attendant. But it does not follow from this psychological theory that Hume denies "real connections" between physical objects and events. On the contrary, he is committed, as the texts reveal, to admitting that there is a "real connection", although he denies that we have any insight into the nature of that connection. Chapter two is intended to settle the dispute over the status of Burne's two definitions of "cause". It is shown that thev are not incompatible, and it is only when both the definitions are taken together that Hume's analysis of causation is complete. In chapter three a detailed defence is undertaken of Hume's claim that we do not know causal connections a priori and that the inference from past experience to future prediction is not rationally justifiable. Although predictions of future events can not be rationally defended, Hume does not reject them, but gives them a naturalistic, psychological explanation. By considering all relevant factors it is shown that Hume's analyses of causation are quite consistent and not subjectivist in the sense often attributed to them. / Thesis / Master of Arts (MA)

Student athletes (SAs) are faced with multiple hurdles upon stepping onto campus, including balancing their lives as a student with that of being an athlete for 20 or more hours per week. SAs typically maintain weekly physical activity (PA) recommendations as a by-product of participation in one’s sport. Because most SAs have high athletic identity, which remains fairly consistent throughout their lives, many incorrectly assume this will translate into a high exercise identity and greater PA throughout their life spans. Certainly, the challenge is how to assist SAs in transitioning from athlete to exerciser. Based on findings from previous research on barriers to maintaining healthy PA levels faced by student-athletes as they transition out of sport, the purpose of this study is to examine the components of resources that can help individuals navigate this transition. Phase I of the study was quantitative in nature and examined the relationship between athletic identity and exercise identity; the relationship was not significant; however, as expected, an individual’s level of exercise identity was related to one’s levels of moderate and vigorous exercise per week. Additionally, individuals with high athletic identity were more likely to participate in vigorous PA. For the purpose of the study, Phase II involved conducted hack groups (typically labeled as focus groups) to gain a deeper understanding of how practitioners can best serve athletes as they transition out of collegiate sport. According to the participants, attention should be given to the delivery method of resources. The most frequently cited form of delivery was that of a phone app with a social network. An app allows for individuals to access an online community of former SAs to not only process their experience but develop connections with like-minded individuals in the area. These connections were highlighted as a motivator for attending exercise groups and act as a form of accountability that may be missing from one’s life after the loss of one’s coach and/or team environment. Former SAs also reported the need for an increased awareness of one’s change in identity and help reframing exercise. Moreover, strategies to build community through authentic connection and shared values, along with assistance developing new routines and habits were deemed important. PA levels or one’s overall well-being may be positively influenced by these connections, but this remains to be studied in depth. The results of the present research indicate a need for attention on activities individuals enjoy rather than exercising for the sake of exercising. Experiencing positive feelings towards PA may in turn allow for increased present-moment awareness in the activity, leading to more enjoyment and potentially increased motivation to maintain PA following the transition out of collegiate sport. / Kinesiology

Some psychologists (e.g., Bergin, 1997) have contended that if individuals neglect the world of the spirit, they ignore a foundational aspect of themselves. This must especially be true for language educators, who come from all corners of the globe and thus bring into their classrooms many spiritual views. I define spirituality, following Palmer (2003) as “the eternal human yearning to be connected with something larger than our own egos” (p. 377). Spirituality need not, then, entail belief in a supernatural being or force. The main thrust of Palmer’s definition was that educators should seek to forge meaningful and lasting connections with their learners. Although such thinking is common in general education, it has been little addressed in Second Language Education (SLE). Hence, I felt that this inquiry was timely. I undertook this qualitative case study by analyzing narratives about the turning points in the spiritual journeys of nine language teachers of varying creeds (or who professed no overt spirituality), as well as their stories of how they felt that they applied their spiritual beliefs to classroom teaching. To this end, I interviewed each participant at least twice. After analyzing their interview transcript data, I triangulated the common themes emerging from these data with, where appropriate, the informants’ classroom syllabuses, lesson plans, and academic publications. I also attempted to validate the results of this study through member checking. Three participants felt that their journeys into religious pluralism had strongly influenced their efforts to teach social responsibility and challenging moral dilemmas in their classrooms. Another three held that their tribulations, as well as the resulting comfort they found in spiritual practices, helped them to be nurturing teachers who could understand clearly the pain faced by some of their young charges. Still another three, despite their divergent spiritual paths, all insisted that they sought to teach in an ethical, caring manner. Finally, most of the informants, regardless of their spiritual backgrounds or views, spoke of the importance of transformation, ethics, and connection (nurturing) to their pedagogy. I conclude the study by positing implications of the aforementioned findings for research and practice. / CITE/Language Arts

This dissertation research examines students’ lived experiences of dance improvisation in a 2014 Hampshire College course titled “Community Crossovers: Dance in the Community” taught by the author. Research methodology is informed by the hermeneutic phenomenology of educational philosopher Max van Manen, dance education research grounded in phenomenological methods by Karen Bond and Susan W. Stinson, among others, and researchers and writers of classroom action research. Sources of qualitative data include students’ reflective writings about their experiences of three selected dance improvisations—Human Puzzle, Mirror, and Approach/Avoid—in both college and community settings. Additional sources contextualizing students’ experiential meanings include course entry questionnaires, videotaped college and community dance sessions, written pedagogical and phenomenological reflections of both the researcher and a teaching assistant, and class discussions. Our Massachusetts community partners were the Treehouse Foundation, Easthampton and the Robert Fitzgerald Kennedy Children’s Action Corps, South Hadley. Student lived experience writings were coded over several cycles to identify categories of meaning in each of the three improvisations at both college and community sites, and these were analyzed for themes across four modes of student participation: self, partner, group and movement (an aesthetic mode). Findings revealed bodily-affective-social-aesthetic meaning making that foregrounds relationality, or connection, through embodied experiences. Students’ descriptions of connection can be understood as qualitatively distinct kinds of felt intersubjectivity: two-person, merged, and other-first. Findings are placed in conversation with literature from dance, community-based education, philosophy, and critical pedagogy. / Dance

This paper describes the 3-dimensional finite element modelling of composite connection with steel beams and precast hollow core slab. A finite element model to simulate the structural behaviour of the composite beam was described and was used to study the behaviour of a wide range of composite connections to gain a better understanding of the structural behaviour especially the moment¿rotation characteristic of the connections. Parametric studies were carried out to investigate the structural behaviour with variations in: size of the beam, thickness of the endplate, thickness of column web, depth of precast hollow cored slab and stud spacing. Through the parametric study, the structural behaviour of the composite connection has been discussed in detail, and recommendations for the design purpose has been made.
