Measurement of Spin Correlations in tt Systems in the muon+jets Channel using a Matrix Element Method with the CMS Detector at the LHC
Get PDFIn this work, the consistency of the spin correlation strength in top quark pair events with the Standard Model (SM) prediction is tested in the muon+jets final state. The events are obtained from pp collisions at a centre-of-mass energy of sqrt(s) = 8 TeV, corresponding to an integrated luminosity of 19.7 fb^(-1). Using a Matrix Element Method, event likelihoods are calculated under two different top quark pair hypotheses: the SM hypothesis and a hypothesis which predicts zero spin correlation. Using the event likelihoods, a variable sensitive to the spin correlation strength is constructed. In a hypothesis testing procedure, the data are found to favour the SM hypothesis. Using a template fit method, the fraction of events that show SM spin correlations is measured to be f = 0.72 +/- 0.08 (stat) +0.15 -0.13 (syst), representing the most precise measurement of this quantity in the lepton+jets channel to date
Measurements of top-quark properties at the LHC
No full textMeasurements of several top-quark properties are presented, obtained from the ATLAS and CMS data collected in 2011 and 2012 at centre-of-mass energies of 7 and 8 TeV. The results include measurements of the top pair charge asymmetry, the top quark polarization in pair production and single top production, the W helicity in top decays. Results of spin correlation in topquark pairs are presented and interpreted in terms of the SM predicted values. The results are compared with predictions from the standard model as well as new physics models. The cross section of ttbar events produced in association with a W, Z boson or a photon is also presented

No full textAs transformações dos modelos de família, no decorrer da história, fizeram com que homens e mulheres se reposicionassem socialmente, sendo a paternidade um tema que sofre impactos dessas transformações e tem sido constantemente revisitado. Esta pesquisa teve como objetivo geral analisar a vivência da paternidade, antes e depois do nascimento, em homens primíparos e, como objetivos específicos, compreender o processo de identificação dos pais com as esposas grávidas, nos períodos pré-natal e puerperal, e analisar os impactos da pandemia no processo de paternidade, nos mesmos períodos. O método utilizado foi o clínico qualitativo e longitudinal, com duas entrevistas realizadas individualmente (uma no pré-natal e outra no puerpério) com cinco homens casados, na faixa etária entre 30 e 36 anos. Do total de participantes 04 eram profissionais de empresas privadas e 01 autônomo, o que repercutiu diversamente no tempo de licença paternidade e na renda salarial, considerando os impactos do isolamento social na pandemia; 02, da raça/cor negra, apresentaram preocupações específicas frente à experiência do racismo que o filho poderá vir a sofrer; as diferentes crenças religiosas também tiveram influência no significado atribuído pelos pais aos filhos. A partir da análise de conteúdo, que considerou a perspectiva psicanalítica, especialmente winnicottiana, foram elaboradas cinco categorias temáticas: 1. Expectativas versus paternidade real; 2. Da invisibilidade ao protagonismo do pai; 3. Da identificação com a mãe à inveja; 4. A pandemia: do isolamento à necessidade de privacidade; 5. A valorização desse novo pai. Considerações finais: compreendeu-se que os participantes da pesquisa possuíam um desejo de também serem protagonistas de ações na interação com os filhos/bebês de modo quase similar às mães. Aos profissionais da saúde mental, psicólogos e psicanalistas, a pesquisa pode contribuir para mostrar a importância de oferecer escuta, revisitar conceitos e colaborar para uma visão mais atualizada que agregue antigos e fortalecidos temas às constatações contemporâneas. Sendo assim, considera-se que é possível que homens sejam pais suficientemente bons, parafraseando o termo winnicottiano de mãe suficientemente boa, uma vez que a característica principal para que esta seja assim considerada é a disponibilidade temporária a uma tarefa única, o que implica em primeiro lugar no desejo, algo que os pais participantes desta pesquisa claramente possuíamTransformations of family models throughout history led men and women to change their social roles and affected paternity, which has been constantly revisited. This research aimed to analyze the experience of fatherhood, before and after child birth in primiparous men. As secondary objectives, it aims to understand the identification process of fathers with pregnant wives in the prenatal and puerperal periods and to analyze the impacts of the pandemic on the paternity process in the same periods. The research has qualitative and longitudinal design and used two interviews carried out individually (one in the prenatal period and the other in the puerperium) with five married men, aged between 30 and 36 years. The sample is described as the following: 04 were professionals from private companies and 01 were self-employed, which brought differences on the time of paternity leave and salary income, given the impacts of social isolation in the pandemic; 02 were black race/color, presented specific concerns regarding the experience of racism that the child may suffer in the future; different religious beliefs also had an influence on the meaning attributed by parents to their children. A content analysis was carried out based on the following thematic categories: 1. Expectations versus real paternity; 2. From invisibility to the role of the father; 3. From identification with the mother to envy; 4. The pandemic: from isolation to the need for privacy; 5. The appreciation of this new father. In general, it was concluded that the sample has a desire to also play a leading role with the children almost likely the mothers. However, there was a lack of information and interventions, mainly by mental health professionals, which included husbands in the preparation for puerperal pregnancy cycle. Finally, the pandemic condition was observed as a possibility to protect the family\'s privacy due to isolation, even adding economic concerns depending on the employment relationship of the participant
Faith, feeling and gender in the writing of Hartley, Wollstonecraft and Blake
Get PDFThis thesis examines David Hartley’s Observations on Man (1749) and elucidates how Hartley’s mechanical approach to mind, his conception of emotion, and the religious status he awards the body were newly relevant after 1791. In this way it identifies a ‘Hartlean culture’ within the Romantic period and seeks to explore how such an intellectual climate influenced the radical writers William Blake (1757–1827) and Mary Wollstonecraft (1759–1797). Blake and Wollstonecraft were acquainted with the famous bookseller Joseph Johnson, who republished Observations on Man in various forms and versions between 1775 and 1801. They also had an association with Johnson’s circle; the Hartlean concepts found throughout their work evidence Hartley’s latent popularity within intellectual culture, as well as the writers’ engagement with contemporary philosophical ideas. I propose that the renewed curiosity in Hartley during the 1790s reveals a specific religious and revolutionary culture wherein non-conformist views about Christianity and new ideas about the body, emotion and women flourished. Such a cultural moment renders Hartley a particularly important figure for debate since he integrated progressive values about equality and faith alongside advancing understanding of anatomy and mind. Hartley identified how God and happiness could be found physically within each person. He did this by combining a complex theory of vibrations and theory of association, where the body and mind functioned mechanically through a person’s feelings of pleasure and pain. These feelings manifested as physical vibrations and eventually led every person to desire goodness until finally, they can become ‘Godlike’ themselves. Hartley’s amalgamation of Christian and new theoretical concepts appealed to Blake and Wollstonecraft, and was much unlike the approach of Joseph Priestley who abridged Observations in 1775 to promote a wholly ‘scientific’ text. In this way, we can see resonances between Hartley, Blake and Wollstonecraft, even if they existed in different cultural contexts. In rethinking Blake and Wollstonecraft through Hartley, I offer new insights into their feminism. In particular I attend to how Hartlean culture enabled these writers to re-imagine gender and emotion: Wollstonecraft reinstates the female experience back into Hartlean concepts in order to promote women’s emotional potential and what she understands as the special power of the female-female bond. Blake responds to both Wollstonecraft and Hartley with his elevation of the feminine, one that envisions new potential for both sexes, emotionally and spiritually. In both cases, the writers share a fascination for the image of the female saviour, and they use terminology and concepts found in Hartley’s work to communicate their views. In being attentive to the shared vocabulary and ideas of these three writers’ works, this thesis highlights the importance of David Hartley and Hartlean culture for the field of Romantic Studies. It also illuminates Observations on Man as a vital contribution to the intellectual context of the 1790s
The Other Side of Silence: Using fiction to explore the resources and limitations in writing about women's lives
Get PDFThis dissertation consists of two distinct components: a creative manuscript, titled “The Other Side of Silence,” and an accompanying exegesis. Both pieces endeavour to answer key questions: What are the different ways fiction might be used to write about the life of a woman from the past? How might we write about such women, taking into account the constraints by which their stories have been forgotten, omitted or displaced? And what are the implications of foregrounding such silences in the writing and reading of narratives?
“The Other Side of Silence” tells the story of Alba, an Italian woman who, with her young family, is leaving her hometown of Salerno for Australia in 1952. The narrative focuses on Alba’s relationship with her mother, Serafina, who fears that Alba’s journey to Australia is motivated by a desire to distance herself from her past. Within this narrative I explore how each of these characters views and consequently deals with the past.
The exegesis discusses several texts that have influenced and inspired “The Other Side of Silence.” In reading contemporary texts about the lives of women in the past, I noted two distinct approaches in the ways women’s stories were written. Some writers use recuperative strategies that allow them to tell stories previously omitted from or distorted by historical discourse and dominant cultural ideologies. By contrast, other writers use poststructuralist narrative strategies to foreground the ways in which traditional realist narratives gloss over the gaps, contradictions and omissions in women’s stories. These alternative narratives indicate how revelation and closure in traditional realism can preclude the probing of some subtle and significant questions about narrating and making sense of women’s experiences. The exegesis examines the different ways writers have challenged and subsequently enlarged conventional notions of realist fiction to imagine and speculate on the possibilities for and limitations on narrative
Thinking the unthinkable: managerialization of work related suicides as a framing process.
Get PDFManagerialism has been studied in many ways, including diffusion of management techniques notably in public sectors, management ideology or the colonization of everyday life by management thought. However, the process leading to managerialism, namely managerialization, has been largely unexplored in this literature. This article draws upon framing theory to better understand managerialization processes. The article offers two case studies that investigate following theoretical assumptions: (1) managerialization acts as a framing process on every kind of issue; (2) managerialization has framing process characteristics. Two frame analysis based on newspaper articles about work related suicide show that one of the identified frames has strong managerial characteristics and suggest that managerialization took place as a set of framing processes. Taken together, these studies provide insight to characterize the process of managerialization. Research implications and limitations are discussed in order to highlight directions for futher researchs.Work related suicide; Framing process; Frame analysis; Managerialism; Managerialization;
Connecting theory and fiction: Margaret Atwood's novels and second wave feminism
Get PDFThis thesis undertakes an examination of the manner in which a novelist interacts with a contemporary theoretical discourse. I argue that the novelist and the theoretical discourse enter into a symbiotic relationship in which each influences and is influenced by the other. This process, I suggest, is simultaneous and complex. The thesis demonstrates how the prevailing theoretical discourse is absorbed by the contemporary author, is developed and redefined in conjunction with alternative concerns, and comes to permeate the narrative in an altered state. The novelist's new perspectives, frequently problematising theoretical claims, are then disseminated by the novel, promoting further discussion and development of the theoretical discourse. The thesis focuses on the novels of Margaret Atwood, considering them in relation to the history and development of second wave feminism. "Second wave feminism" is understood as an umbrella term that incorporates a wide variety of related but diverse and occasionally contradictory discourses, centring on the subjects of gender, femininity, and sexuality. The focus of the discussion is dual and presented simultaneously. Atwood's novels are analysed chronologically, and within the parameter of this analysis I demonstrate how her work has been influenced by earlier feminist theories, how it comments upon a variety of contemporary feminist ideas, and how it can be seen to anticipate further discussions within feminist discourse. Finally, I identify moments in Atwood's writing when alternative discourses compete with feminism to create new directions for feminist criticism. Examples of these discourses include Canadian nationalism, liberalism, communitarianism and environmentalism. The specificity of the novelist's interests and politics create a unique site of interaction for feminism which, I argue, benefits feminist theory by challenging, broadening and diversifying its focus. The thesis concludes that the symbiotic relationship of the theorist and the novelist is self-perpetuating and is also necessary and beneficial to both parties
Identity and consumption practices of Northamptonshire Caribbeans c.1955-1989
No full textThe objective of this thesis is to delineate and analyse Northamptonshire Caribbeans' consumption c.1955-1989. Author-collected and other oral histories alongside complementary primary and secondary references dovetail to unearth and analyse aspects of Post-War Caribbean consumption in a British provincial location that have been significantly unexplored previously. Central to the argument is the contention that identity is fundamentally significant in comprehending and analysing Northamptonshire Caribbeans' consumption. Various conceptualisations of identity facilitated development of consumer materialisations and aspirations. This thesis explores how multiple forms of identity as Caribbean, Black and British people were significant in shaping local Caribbeans' consumption. The succeeding pages address and analyse how these multiple identities influenced consumption and how provincial consumer behaviour was shaped by Caribbeans' relative co-ethnic isolation in Northamptonshire. Chapter 3 delineates and analyses consumer practices and practicalities of Northamptonshire Caribbeans. Integral within these consumer practices and practicalities are changes in consumption over time, intergenerational differences in consumption, as well as aspects of consumption that could be considered 'typical' and/or 'atypical' Northamptonshire Caribbean consumption; all of which are incorporated within this chapter. Chapter 4 connects identity and consumption through enhancing understanding of Northamptonshire Caribbeans' consumer networks. These networks interacted with the combination of identities local Caribbeans psychologically felt part of within various Caribbean, Black and British permutations. Furthermore, such identities varied more widely amongst the younger generation than their co-ethnic elders, a concept which is also addressed. Education and cultural currency are two novel strands through which to analyse connections between consumption and identity. The final two chapters deploy these concepts in an innovative manner creating and developing greater understanding of Northamptonshire Caribbeans' consumption. Chapter 5 expounds on the concept that education can be used as consumption whilst shaping future consumer behaviour, both ideas significantly under-explored previously. Chapter 6 introduces the theory of cultural currency, the idea that aspects of culture have finite, but changing, values and must be shared to have value similar to monetary currencies having exchange values for other monetary currencies. This chapter demonstrates how Northamptonshire Caribbeans shared aspects of Caribbean culture as cultural currency, fostering co-ethnic strength whilst gaining inter-ethnic respect for Caribbeans. Through comprehending Caribbean identity, correlations between empirical and social history, local consumption, as well as educational and cultural circumstances that stimulated and inspired Northamptonshire Caribbeans, this thesis distinctively illuminates how local Caribbeans' consumption interacted with various permutations of Afro-Caribbean, Black and/or British identities whilst representing idiosyncratic local nodes within these larger amalgamations
Dialogues of Psychology with Michel Foucault
No full textAbstract The purpose of this article is to discuss how psychology in Brazil has dialogued with philosopher Michel Foucault’s theorizations. We present the results of an investigation that analyzed scientific articles of psychology that use the theoretical and methodological tools of the author. These articles were published in indexed electronic journals and are available on the website of the Virtual Health Library (Biblioteca Virtual em Saúde, BVS-Psi). The results point to an increasing use of the author since the early 2000s, especially in social psychology. The main points of articulation with the Foucauldian thought were: the problematization of the scientific production itself, questioning its neutrality and affirming, therefore, its political dimension; the analysis of the interrelationship between the production of discourses and modes of subjectivity connected to governmentality practices, biopolitics strategies, and normalization of life; and, finally, the questioning of psychological practices as ethical devices of subjectification.</p
“THIS WILL NOT KILL US:” A REFLECTIVE EXPLORATION OF HOW BLACK WOMEN DOCTORAL STUDENTS AND ALUMNAE STRIVED FOR HOLISTIC MENTAL HEALTH AND WELLNESS
No full textThe purpose of this qualitative research study was to develop a better understanding of the factors that influenced the holistic mental health and wellness of Black women doctoral students and recent alumnae during their doctoral journey. Although research is emerging on the wellness of graduate students, there is limited literature on Black women doctoral students’ wellness. From 2020 to 2023 there were national events involving Black women that underscored the necessity to understand and prioritize the holistic wellness of Black women doctoral students (e.g. Black women in higher education leaving their high-ranking positions and Naomi Osaka and Simone Biles taking a break from their respective sports and citing mental health as a factor). Using narrative inquiry as a methodological approach, and a conceptual framework comprised of Black feminist thought (Collins, 1986, 1989) and Hettler’s (1980, 1984) six dimensions of wellness, the experiences of nine Black women doctoral students and recent alumnae (who were no more than six-months post-graduation) were explored. This research sought to understand the strategies Black women doctoral students and recent alumnae used to manage and maintain their holistic mental health and wellness. The specific research questions that guided this study are: (1) How do Black women doctoral students and recent alumnae at Research 1 (R1) or Research 2 (R2) institutions in the mid-Atlantic region describe their mental health and wellness while pursuing their doctoral degree? (2) What contributed to and interfered with the holistic mental health and wellness of Black women doctoral students and recent alumnae during their doctoral programs?Co-narrators (participants of the study) participated in two semi-structured interviews, each ranging from 60 to 90 minutes in length. Data collection also included co-narrators submitting memes or gifs that represented their mental health and wellness during their doctoral journey. There were several themes that emerged from the data. First, the visual data revealed that co-narrators experienced exhaustion, anguish, fluctuation between joy and stress, and the need to keep moving forward despite what was happening around them. The images submitted served as a visual representation for the overall experiences of the women in the study and enhanced the understanding of the factors that contributed to or interfered with the holistic mental health and wellness of Black women doctoral students (i.e., Research Question 2). The additional findings that emerged from study are as follows: (a) “Wellness for Your Whole Body:” Co-Narrators Definitions of Holistic Mental Health and Wellness; (b) Factors that Contributed to Holistic Wellness, including the subthemes “They Needed the Sisterhood:” The Importance of Community with Other Black Women, and “Finding Those Pockets:” Intentionally Choosing Wellness in the PhD Journey; (c) Positive and Negative Contributing Factors to Holistic Mental Health and Wellness, which included the subthemes “All Skin Folk Ain’t Kinfolk:” Interactions with Challenging Black Faculty and Administrators, and “My Advisor . . . Was Super Supportive:” How Relationships with Black Faculty and Non-Black Faculty and Administrators of Color Can Influence Wellness; (e) Detractors From Holistic Mental Health and Wellness, which included the subthemes “The PhD Program Is Good About . . .Letting You Know You Don’t Belong:” Impostorism and Lack of Belonging in the Academy and “What Is the Benefit of . . . Being Productive, If You’re Literally Killing Yourself?”: Negotiating Wellness to Finish the PhD. The study concluded with implications for practice and research, followed by a letter from the author directly addressing Black women doctoral students
