Beating the urge: Implications of research into substance-related desires

Despite the advent of improved pharmacological treatments to alleviate substance-related desires, psychological approaches will continue to be required. However, the current psychological treatment that most specifically focuses on desires and their management-cue exposure (CE)-has not lived up to its original promise. This paper argues that current psychological approaches to desire do not adequately incorporate our knowledge about the factors that trigger, maintain, and terminate episodes of desire. It asserts that the instigation and maintenance of desires involve both associative and elaborative processes. Understanding the processes triggering the initiation of intrusive thoughts may assist in preventing some episodes, but occasional intrusions will be inevitable. A demonstration of the ineffectiveness of thought suppression may discourage its use as a coping strategy for desire-related intrusions, and mindfulness meditation plus cognitive therapy may help in accepting their occurrence and letting them go. Competing tasks may be used to reduce elaboration of desires, and competing sensory images may have particular utility. The application of these procedures during episodes that are elicited in the clinic may allow the acquisition of more effective strategies to address desires in the natural environment.

CULTURA ORGANIZACIONAL, REPRESENTAÇÕES DE GÊNERO E RELIGIÃO: TENSÕES, CONTRADIÇÕES E TENDÊNCIAS

Nas sociedades ocidentais contemporâneas, racionais e secularizadas, a religião é freqüentemente representada como externa à razão‟ e de foro ìntimo, idéias estas implìcitas na máxima religião não se discute‟. Ela estaria no campo oposto, portanto, daquele do mundo organizacional, sujeito à racionalidade, à objetividade do cálculo e à impessoalidade e do qual se abstrairiam o mundo privado da religião, das atividades domésticas e tudo o mais que se supõe ser de caráter pessoal e avesso ao cálculo. A idéia de que a igualdade entre os sexos já está consumada também faz parte do imaginário contemporâneo: a maior autonomia e presença das mulheres no espaço público, particularmente o aumento da sua participação no mercado de trabalho, seriam evidências de que a igualdade constitui uma batalha ganha. No entanto as representações de gênero continuam a configurar tal presença (ou ausência) feminina no mercado de trabalho. Da mesma maneira, as idéias religiosas e acerca das religiões não são passíveis de confinamento a tempos e espaços precisos, do culto, da meditação ou da prática religiosa. Tanto as representações de gênero quanto aquelas acerca da religião e da diversidade religiosa interpenetram o espaço público, o dia-a dia da vida e das relações sociais, as relações de gênero e de trabalho. Elas se inscrevem nas normas e práticas organizacionais, nas técnicas de gestão e os/a próprios sujeitos trabalhadores/as também bricolam e transitam entre esses mundos na construção das suas competências e na gestão da sua atividade profissional. A pergunta por aspectos e maneiras pelas quais representações de gênero, da religião e da diversidade religiosa, suas especificidades em determinado contexto social, se desdobram e entrecruzam em percepções e práticas no ambiente organizacional, e vice-versa, em que medida estas apontam para tensões e tendências presentes na sociedade circundante, constitui-se no fio condutor da presente tese. Além de pesquisa bibliográfica a metodologia contempla pesquisa de campo em duas organizações empresariais francesas no Brasil e na França.

RESILIÊNCIA EM IDOSOS QUE MEDITAM

Resiliência é definida como a capacidade das pessoas em enfrentar, vencer e serem fortalecidos ou transformados por experiências adversas. Estudos têm mostrado que pessoas resilientes adoecem menos e possuem melhor desempenho no trabalho, nas relações familiares e na vida, além da resiliência poder ser desenvolvida desde a infância até a velhice. Por sua vez, a meditação tem mostrado ser um recurso útil para a melhoria da saúde em geral, incluindo a qualidade de vida daqueles que a praticam por proporcionar maiores níveis de bem estar, melhoria nos relacionamentos interpessoais e redução de estresse. Parece que a meditação, assim como a resiliência, pode contribuir para melhores níveis de saúde da população. O objetivo deste estudo foi verificar os níveis de resiliência em idosos que meditam. Participaram 60 pessoas, sendo 78% mulheres, com idade média de 69 anos, 82% aposentados, 65% praticantes de meditação, 42% com baixa escolaridade e 60% católicos. O instrumento utilizado foi um questionário auto-aplicável, composto pela Escala de Avaliação de Resiliência (EAR) em sua forma reduzida e um questionário para coletar dados sociodemográficos dos participantes. Análise de variância revelou não haver diferença nos níveis de resiliência entre o grupo que medita uma vez ao dia e aquele que o faz mais do que uma vez ao dia. Médias fatoriais e desvios-padrão revelaram que os participantes possuem capacidade levemente acima da média de adaptarem-se positivamente diante das dificuldades da vida, persistindo para superar crises e adversidades, poucas vezes se resignando, embora algumas vezes não se julguem competentes para enfrentá-las. Para defrontarem as dificuldades da vida, contam com as crenças de que podem confiar no apoio de um ente ou algo superior e acreditam que podem aprender e melhorar com as adversidades.

O EFEITO DO CONTROLE RESPIRATÓRIO EM VARIÁVEIS ELETROFISIOLÓGICAS DA ATENÇÃO

A prática do ioga tem se tornado cada vez mais popular, não apenas pelos benefícios físicos, mas principalmente pelo bem-estar psicológico trazido pela sua prática. Um dos componentes do ioga é o Prãnãyama, ou controle da respiração. A atenção e a respiração são dois mecanismos fisiológicos e involuntários requeridos para a execução do Prãnãyama. O principal objetivo desse estudo foi verificar se variáveis contínuas do EEG (potência de diferentes faixas que o compõem) seriam moduladas pelo controle respiratório, comparando-se separadamente as duas fases do ciclo respiratório (inspiração e expiração), na situação de respiração espontânea e controlada. Fizeram parte do estudo 19 sujeitos (7 homens/12 mulheres, idade média de 36,89 e DP = ± 14,46) que foram convidados a participar da pesquisa nas dependências da Faculdade de Saúde da Universidade Metodista de São Paulo. Para o registro do eletroencefalograma foi utilizado um sistema de posicionamento de cinco eletrodos Ag AgCl (FPz, Fz, Cz, Pz e Oz) fixados a uma touca de posicionamento rápido (Quick-Cap, Neuromedical Supplies®), em sistema 10-20. Foram obtidos valores de máxima amplitude de potência (espectro de potência no domínio da frequência) nas frequências teta, alfa e beta e delta e calculada a razão teta/beta nas diferentes fases do ciclo respiratório (inspiração e expiração), separadamente, nas condições de respiração espontânea e de controle respiratório. Para o registro do ciclo respiratório, foi utilizada uma cinta de esforço respiratório M01 (Pletismógrafo). Os resultados mostram diferenças significativas entre as condições de respiração espontânea e de controle com valores das médias da razão teta/beta menores na respiração controlada do que na respiração espontânea e valores de média da potência alfa sempre maiores no controle respiratório. Diferenças significativas foram encontradas na comparação entre inspiração e expiração da respiração controlada com diminuição dos valores das médias da razão teta/beta na inspiração e aumento nos valores das médias da potência alfa, sobretudo na expiração. Os achados deste estudo trazem evidências de que o controle respiratório modula variáveis eletrofisiológicas relativas à atenção refletindo um estado de alerta, porém mais relaxado do que na situação de respiração espontânea.

Dapsone hydroxylamine induces premature removal of human erythrocytes by membrane reorganization and antibody binding

N-hydroxylation of dapsone leads to the formation of the toxic hydroxylamines responsible for the clinical methaemoglobinaemia associated with dapsone therapy. Dapsone has been associated with decreased lifespan of erythrocytes, with consequences such as anaemia and morbidity in patients treated with dapsone for malaria. Here, we investigated how dapsone and/or its hydroxylamine derivative (DDS-NHOH) induced erythrocyte membrane alterations that could lead to premature cell removal.

Hacia una poetica del Neobarroco: La vision de la historia en Jose Lezama Lima, Reinaldo Arenas y Severo Sarduy

Most of the critical studies of Baroque novels written in Spanish America during the 1960s and 1970s are characterized by a limited examination of their formal and stylistic representations. This dissertation explored the way in which certain writers developed a new Baroque tendency, the so-called Neobarroco, that presented a particular vision of history. José Lezama Lima, Reinaldo Arenas and Severo Sarduy developed innovative fictional and historiographic perceptions as alternative discourses to understand and perceive the cultural intricacies of Cuba and the New World. Their novels posited an elaborated poetic theory of history that can be summarized by the principle of supratemporal analogies, interweaved by a "metaphoric subject" that makes possible the conception of "imaginary eras". Since this poetry arises from a network of metaphoric correspondences, the image is conceived as a cultural creation that acts upon reality. ^ Although this study traced the trajectory of their writings from the point of view of their own essays, our focus was on the act of recovering the past as reshaped forms that are present in the memory. Paradiso, El mundo alucinante and De donde son los cantantes exemplified the attempt to place Americanness within the realm of poetics and history as one single discourse constructed by a combination of self-consciousness and historiographic meditation. ^ Basing my thesis on postmodernist theory (Ihab Hassan, Brian McHale, Linda Hutcheon) and philosophies of history (Michel Foucault, Hayden White, Keith Jenkins, Dominick LaCapra), I argued that the antagonistic paradoxes faced by postmodernism were reconcilable tendencies of the Neobarroco prior to the actual debate on the postmodern condition. The aesthetic trend initiated by these writers and their reading of history confronted the official historiographic discourse, thus empowering a contemporary voice in the current debate on historical skepticism. ^

Grey Slate

GREY SLATE is a collection of poems that focuses on the natural world in order to explore the mysteries of life with the intent to create a meditation on what it means to be a human being interacting with this world. Inspired by John Keats’ theory of Negative Capability, GREY SLATE does not seek to explain, but to dwell in the mysteries it explores. The poems are tied together through similar images or ideas in order to mimic the way the mind works as it jumps from thought to thought. GREY SLATE also mixes different types of poems: from haiku to sonnet to paradelle, and from lyric to narrative to prose poem. GREY SLATE hopes to inspire readers to take a break from searching for truths and indulge in the beautiful mystery that is life with no need for answers.

American Manna: Religious Responses to the American Industrial Food System

“American Manna: Religious Responses to the American Industrial Food System” is an investigation of the religious complexity present in religious food reform movements. I conducted ethnographic fieldwork at four field sites. These field sites are a Jewish organic vegetable farm where the farmers begin their days with meditation, a Christian raw vegan diet center run by Messianic Jews, a Christian family that raises their cattle on pastures and sends them to a halal processing plant for slaughter, and a Jewish farm where Christian and Buddhist farm staff helped to implement shmita, the biblical agricultural sabbatical year.

The religious people of America do not exist in neatly bound silos, so in my research I move with the religious people to the spaces that are less clearly defined as “Christian” or “Jewish.” I study religious food reformers within the framework of what I have termed “free-range religion” because they organize in groups outside the traditional religious organizational structures. My argument regarding free-range religion has three parts. I show that (1) perceived injustices within the American industrial food system have motivated some religious people to take action; (2) that when they do, they direct their efforts against the American food industry, and tend to do so outside traditional religious institutions; and finally, (3) in creating alternatives to the American food industry, religious people engage in inter-religious and extra-religious activism.

Chapter 1 serves as the introduction, literature review, and methodology overview. Chapter 2 focuses on the food-centered Judaism at the Adamah Environmental Fellowship at the Isabella Freedman Jewish Retreat Center in Falls Village, CT. In Chapter 3, I discuss the Hallelujah Diet as prescriptive literature and as it is put into practice at the Hallelujah Diet Retreat Center in Lake Lure, NC. Chapter 4 follows cows as they move from the grassy hills of Baldwin Family Farms in Yanceyville, NC to the meat counter at Whole Foods Markets. In Chapter 5, I consider the shmita year, the biblical agricultural sabbatical practice that was reimagined and implemented at Pearlstone Center in Baltimore, MD during 2014-2015. Chapter 6 will conclude this dissertation with a discussion of where religious food reform has been, where it is now, and a glimpse of what the future holds.

Shaping Religious and Cultural Aspiration: Engraved Sutras in Southwestern Shandong Province from the Northern Qi Dynasty (550-577 CE), China

This dissertation explores how the Buddhist texts carved on the cliffs of mountains served their patrons’ religious and cultural goals. During the Northern Qi period (550-577 CE), these carved Buddhist sutra texts and Buddha names were prevalent, and were carved directly onto the surfaces of numerous mountains in southwestern Shandong Province. The special focus of this study is on the Buddhist engravings at Mt. Hongding in Dongping, and at Mt. Tie in Zoucheng. Created in approximately 553-564 CE, the carvings at Mt. Hongding stand as the terminus a quo of the history of Buddhist sutras carved into the rocks of the Shandong mountains. The Buddhist carvings at Mt. Hongding served monastic goals. The monk patrons, Seng’an Daoyi, Fahong, and others created the carvings as an integral part of their Buddhist meditation practices. The carvings at Mt. Tie paint a very different picture. At Mt. Tie, a colossal Buddhist sculpture-style carving was created in 579 CE. Sponsored by several Han Chinese patrons, the carving was designed in the form of a gigantic Chinese traditional stele. This study suggests that several Han Chinese local elites proudly displayed their Han Chinese linage by using the gigantic stele form of Buddhist text carving as a means to proclaim Han Chinese cultural and artistic magnificence. To achieve these non-religious goals, they appropriated rhetorical devices often used by the Han elite, such as the stele form, written statements about the excellence of the calligraphy used, and discourse on calligraphy connoisseurship.

The Role of Home Practice Engagement in a Mindfulness-Based Intervention

Over the last three decades, there has been a precipitous rise in curiosity regarding the clinical use of mindfulness meditation for the self-management of a broad range of chronic health conditions. Despite the ever-growing body of evidence supporting the use of mindfulness-based therapies for both medical and psychological concerns, data on the active ingredients of these mind-body interventions are relatively scarce. Regular engagement in formal mindfulness practice is considered by many to be requisite for generating therapeutic change; however, previous investigations of at-home practice in MBIs have produced mixed results. The equivocal nature of these findings has been attributed to significant methodological limitations, including the lack of standardized, systematic practice monitoring tools, and a singular focus on practice time, with little attention paid to the nature and quality of one’s practice. The present study used a prospective, observational design to assess the effects of home-based practice on dispositional mindfulness, self-compassion, and psychological functioning in twenty-eight people enrolled in an MBSR or MBCT program. To address some of the aforementioned limitations, the present study collected detailed weekly accounts of participants’ home-based practice engagement, including information about practice time (i.e., frequency and duration), exercise type, perceived effort and barriers to participation, and practice quality. Hierarchical multiple regression was used to examine the relative contribution of practice time and practice quality on treatment outcomes, and to explore possible predictors of adherence to at-home practice recommendations. As anticipated, practice quality and perceived effort improved with time; however, rather unexpectedly, practice quality was not a significant predictor of treatment-related improvements in psychological health. Home practice engagement, however, was predictive of change in dispositional mindfulness, in the expected direction. Results of our secondary analyses demonstrated that employment status was predictive of home practice engagement, with those who were unemployed completing more at-home practice on average. Mindfulness self-efficacy at baseline and previous experience with meditation or other contemplative practices were independently predictive of mean practice quality. The results of this study suggest that home practice helps generate meaningful change in dispositional mindfulness, which is purportedly a key mechanism of action in mindfulness-based interventions.

Walking with God through Nature: An Examination of John Flavel’s Behavioural Instructions on Matters Related to Christian Piety

John Flavel was a Reformed Puritan of the seventeenth-century who wrote a series of devotional guides that offered instructions drawn from Christian mystical traditions on how to improve religious activities as a means of ecstatically encountering God. Evaluating the efficacy of these instructions from a scientifically-based behavioural perspective, this study has found that Flavel’s techniques were likely helpful to his readers in facilitating socially normative ecstatic experiences through ordinary Christian practice. Furthermore, discovering that Flavel promoted the use of these techniques for engaging with ecological materials in the wilderness and country-side, this essay proposes that Flavel introduced his readers to effectual manners that could help them ecstatically encounter God during the practice of meditational nature-based walks.

‘The voice speaking, desired, awaited’: Jack Lindsay’s 1649, Textual Form and Communist Historiography

This article examines the 1938 historical novel 1649: A Novel of a Year by the Anglo-Australian communist polymath Jack Lindsay in the context of the politics of the Popular Front, and identifies the aesthetic and historiographic debates questions that inform Lindsay’s inventive rendition of the historical novel. The novel may be considered in light of what Lindsay later called his desire ‘to use the novel to revive revolutionary traditions’, as well as his ‘struggle to achieve an understanding of the Novel while writing novels’. Lindsay’s novel figures a reality becoming prosaic: it reproduces contemporary textual sources – tracts, pamphlets, newspapers – as part of its meditation on a nascent print culture whose products circulate in processes that mirror the increasingly conspicuous flow of commodities. In this sense, the novel offers a marxist reflection on its own conditions of possibility in emergent bourgeois culture, as well as intervening in the vexed question of the Civil War as a ‘bourgeois revolution’. The novel however seeks to capture a dialectical method of representing the revolution that acknowledges defeat while rearticulating the utopian content of the defeated radicals, a practice integral to Lindsay’s vision of popular history as a transhistorical dialogue. That utopian content is transmitted through two forms: popular song, which acts to supplement political writing; and the heroic portrayal of the Leveller John Lilburne on trial, whose conduct exemplifies praxis conceived as a unity of word, thought and action.

Rethinking Care Through Social Reproduction: Articulating Circuits of Migration

Care has come to dominate much feminist research on globalized migrations and the transfer of labor from the South to the North, while the older concept of reproduction had been pushed into the background but is now becoming the subject of debates on the commodification of care in the household and changes in welfare state policies. This article argues that we could achieve a better understanding of the different modalities and trajectories of care in the reproduction of individuals, families, and communities, both of migrant and nonmigrant populations by articulating the diverse circuits of migration, in particular that of labor and the family. In doing this, I go back to the earlier North American writing on racialized minorities and migrants and stratified social reproduction. I also explore insights from current Asian studies of gendered circuits of migration connecting labor and marriage migrations as well as the notion of global householding that highlights the gender politics of social reproduction operating within and beyond households in institutional and welfare architectures. In contrast to Asia, there has relatively been little exploration in European studies of the articulation of labor and family migrations through the lens of social reproduction. However, connecting the different types of migration enables us to achieve a more complex understanding of care trajectories and their contribution to social reproduction.

Determination of multi-mycotoxin occurrence in maize based porridges from selected regions of Tanzania by liquid chromatography tandem mass spectrometry (LC-MS/MS), a longitudinal study

Residents of certain areas of Tanzania are exposed to mycotoxins through the consumption of contaminated maize based foods. In this study, 101 maize based porridge samples were collected from villages of Nyabula, Kikelelwa and Kigwa located in different agro-ecological zones of Tanzania. The samples were collected at three time points (time point 1, during maize harvest; time point 2, 6 months after harvest; time point 3, 12 months after harvest) over a 1-year period. Ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) was used to detect and quantify 9 mycotoxins: aflatoxin B1 (AFB1), aflatoxin B2 (AFB2), aflatoxin G1 (AFG1), aflatoxin G2 (AFG2), fumonisin B1 (FB1), fumonisin B2 (FB2), deoxynivalenol (DON), ochratoxin A (OTA) and zearaleneone (ZEN) in the samples following a QuEChERS extraction method. Eighty two percent of samples were co-contaminated with more than one group of mycotoxins. Fumonisins (FB1 + FB2) had the highest percentage occurrence in all 101 samples (100%) whereas OTA had the lowest (5%). For all three villages the mean concentration of FB1 was lowest in samples taken from time point 2. Conversely, In Kigwa village there was a distinct trend that AFB1 mean concentration was highest in samples taken from time point 2. DON concentration did not differ greatly between time points but the percentage occurrence varied between villages, most notably in Kigwa where 0% of samples tested positive. ZEN occurrence and mean concentration was highest in Kikelelwa. The results suggest that mycotoxin contamination in maize can vary based on season and agro-ecological zones. The high occurrence of multiple mycotoxins found in maize porridge, a common weaning food in Tanzania, presents a potential increase in the risk of exposure and significant health implications in children.
