WRN Cys1367Arg SNP is not associated with risk and prognosis of gliomas in Southeast Brazil

Werner syndrome (WS) is a premature aging disorder characterized by early onset of symptoms related to normal aging and by a high predisposition to various types of cancer, including gliomas. WS is caused by inherited recessive mutations in the WRN gene, which encodes a helicase considered a caretaker of the genome. Aiming to study the role of WRN Cys1367Arg in glioma susceptibility and oncologic prognosis of patients, we investigated the genotype distribution of this single nucleotide polymorphism in 94 glioma patients and 100 healthy subjects. Comparisons of genotype distributions and allele frequencies did not reveal any significant difference between the groups. Overall and disease-free survival rates were calculated, but no statistically significant difference was observed. Our data suggest that WRN Cys1367Arg SNP is not involved either in susceptibility to developing gliomas or in patient survival, at least in the Brazilian population.

The History of Rome in Painting

There are many paths to reach Rome, immense field open to the eye through the centuries and days, where the presence of the story is haunting. All the artists came to Rome: Italians of various Italian and also French, Dutch, Flemish, Spanish, English and Americans. These painters whose works tell its long history for having lived in the glare of light forever are the Roman pantheon of arts: what are all the anonymous authors of the frescoes of ancient Rome and medieval, but Fabriano, Cimabue , Giotto, Botticelli, Raphael, Giulio Romano, Michelangelo, Caravaggio, Guido Reni, Guercino, Titian, Vasari, Velasquez, Le Nain, Poussin, Zuccari, Van Wittel, Eckersberg, Giraudet, David, Panini, Hubert Robert, Reynolds, Fuseli, Ingres, Sargent, Caffi, Vernet, Turner, Corot, Caffi, De Chirico, etc..

Discordances between phylogenetic and morphological patterns in alpine leaf beetles attest to an intricate biogeographic history of lineages in postglacial Europe.

Pleistocene glacial and interglacial periods have moulded the evolutionary history of European cold-adapted organisms. The role of the different mountain massifs has, however, not been accurately investigated in the case of high-altitude insect species. Here, we focus on three closely related species of non-flying leaf beetles of the genus Oreina (Coleoptera, Chrysomelidae), which are often found in sympatry within the mountain ranges of Europe. After showing that the species concept as currently applied does not match barcoding results, we show, based on more than 700 sequences from one nuclear and three mitochondrial genes, the role of biogeography in shaping the phylogenetic hypothesis. Dating the phylogeny using an insect molecular clock, we show that the earliest lineages diverged more than 1 Mya and that the main shift in diversification rate occurred between 0.36 and 0.18 Mya. By using a probabilistic approach on the parsimony-based dispersal/vicariance framework (MP-DIVA) as well as a direct likelihood method of state change optimization, we show that the Alps acted as a cross-roads with multiple events of dispersal to and reinvasion from neighbouring mountains. However, the relative importance of vicariance vs. dispersal events on the process of rapid diversification remains difficult to evaluate because of a bias towards overestimation of vicariance in the DIVA algorithm. Parallels are drawn with recent studies of cold-adapted species, although our study reveals novel patterns in diversity and genetic links between European mountains, and highlights the importance of neglected regions, such as the Jura and the Balkanic range.

Appropriateness of use of infliximab in the Swiss IBD Cohort Study

Introduction: Anti-TNFs have significantly improved the management of Crohn's disease (CD), but not all patients will benefit from this therapy. We used data from the Swiss IBD Cohort Study (SIBDCS) and preset appropriateness criteria to examine the appropriateness of use of infliximab (IFX) in CD patients. aims & methods: EPACT II (European Panel on the Appropriateness of Crohn's disease Therapy) appropriateness criteria (www.epact.ch) have been developed by a formal panel process combining evidence from the published literature and expert opinion (end 2007), yielding 3 categories of indications: appropriate, uncertain, and inappropriate. Enrolment and follow-up of all SIBDCS patients were achieved with questionnaires relating to EPACT II criteria. Patients could correspond to several clinical categories; pregnant patients or those with stenosing disease could not be assessed using EPACT II criteria. A step-by-step analysis based on frequency allowed identification of the most appropriate indication for IFX in a given patient. results: 822 CD patients were included between November 2006 and March 2009. 146 patients (18%) were on IFX at inclusion (130 maintenance of remission, 16 new treatments). At inclusion, and in comparison with non-IFX treated patients, patients on infliximab were more frequently female (56% vs 51%), younger at diagnosis (27.4 years old vs 30.4) and had a slightly shorter disease duration (10.3 years vs 11.7). Disease extension was greater in these patients, who were mainly treated in university centres (83% vs 72%). IFX therapy was considered appropriate in 47%, uncertain in 36% and inappropriate in 18 % of patients (6% of situations could not be assessed). conclusion: In this cohort, most indications (47%) for IFX therapy were appropriate. Uncertain or inappropriate indications were mostly due to complex patient characteristics (e.g. complex fistulas, history of multiple drug-failures), which reflect the broad use of IFX in clinical practice. Cohort studies are well suited to evaluating the implementation of new scientific evidence in clinical practice.

Psychiatric co-morbidities and cardiovascular risk factors in people with lifetime history of epilepsy of an urban community.

OBJECTIVES: Depression has been consistently reported in people with epilepsy. Several studies also suggest a higher burden of cardiovascular diseases. We therefore analysed psychosocial co-morbidity and cardiovascular risk factors in patients with a lifetime history of epilepsy in the PsyCoLaus study, a Swiss urban population-based assessment of mental health and cardiovascular risk factors in adults aged between 35 and 66 years. PATIENTS AND METHODS: Among 3719 participants in the PsyCoLaus study, we retrospectively identified those reporting at least 2 unprovoked seizures, defined as epilepsy. These subjects were compared to all others regarding psychiatric, social, and cardiovascular risk factors data using uni- and multivariable assessments. RESULTS: A significant higher need for social help (p<0.001) represented the only independent difference between 43 subjects with a history of epilepsy and 3676 controls, while a higher prevalence of psychiatric co-morbidities (p=0.015) and a lower prevalent marital status (p=0.01) were only significant on univariate analyses. Depression and cardio-vascular risk factors, as well as educational level and employment, were similar among the groups. CONCLUSIONS: This analysis confirms an increased prevalence of psychosocial burden in subjects with a lifetime history of epilepsy; conversely, we did not find a higher cardiovascular risk. The specific urban and geographical location of our cohort and the age span of the studied population may account for the differences from previous studies.

The role of vectors in the epidemiology of avian malaria

Studies on host-parasite relationships have commonly reported that parasitized hosts undergo changes in their behavioural and life history traits. How do these changes affect the fitness of the hosts? What are the ecological and evolutionary drivers of these changes? These open questions are crucial to predict the parasite spread amongst hosts. Surprisingly, mosquito vectors of diseases to humans and animals have long been seen as passive parasite transporters, being unaffected by the infection though they also function as hosts. Natural parasite-vector interactions are therefore poorly documented in the literature. In this thesis, we seek to address the role of wild vectors in the epidemiology of avian Plasmodium, the etiological agents of malaria in birds. We first conducted avian malaria surveys in field-caught mosquitoes to identify the natural vectors in our temperate study area. We report that ornithophilic Culex pipiens primarily act as a vector for Plasmodium vaughani in spring, this parasite species being progressively replaced by P. relictum along with the season. Season-related factors may thus shape the mosquitoes' vectorial capacity. We then used experimental approaches to determine the effect of avian malaria on wild, naturally infected C. pipiens. We show that infected mosquitoes incur unavoidable physiological costs associated with parasite exploitation, these costs being expressed as a reduced survival under nutritionally stressed conditions only. These results are of significant importance for the epidemiology of avian malaria since seasonal changes in climate may likely influence food quality and quantity available to the mosquitoes. The host-selection preferences of the vectors with respect to the malaria-infection status of their bird hosts largely determine the disease spreading. In a second laboratory experiment, we thus offered wild C. pipiens the opportunity to choose between uninfected and naturally infected great tits, Parus major. We show that host-seeking mosquitoes have innate orientation preferences for uninfected birds. This suggests that avian malaria parasites exert strong selective pressures on their vectors, pushing them to evolve anti-parasite behaviours. We lastly investigated the links between malaria-associated symptoms in birds and resulting attractiveness to the mosquitoes. We show that experimentally malaria-infected canaries, Serinus canaria, suffer severe haematocrit reduction at peak parasitaemia and reduced basal metabolic rate later in the course of the infection. However, no links between infection and bird attractiveness to the mosquitoes were shown in an experiment using canaries as live bait for mosquito trap in the field. These links may have been masked by confounding environmental factors. Using a system where the vectors, parasites and hosts co-occur in sympatry, this thesis illustrates that vectors are not always Plasmodium permissive, which opposes to the traditional view that malaria parasites should have little effect on their vectors. The way that the vectors respond to the parasite threat is largely determined by the environmental conditions. This may have major implications for the epidemiology of avian malaria. - Les études portant sur les relations hôtes-parasites mentionnent souvent que les hôtes parasités subissent des modifications de leurs traits d'histoire de vie ou bien comportementaux. Comment ces changements affectent-ils la valeur sélective des hôtes et celle de leurs parasites ? Quels sont les déterminants de ces modifications ? Ces questions sont d'un grand intérêt en épidémiologie. Pour autant, les moustiques vecteurs de maladies infectieuses ont longtemps été perçus comme de simples transporteurs de parasites, n'étant pas affectés par ces derniers. Cette thèse porte sur le rôle des vecteurs dans l'épidémiologie des Plasmodium aviaires, agents étiologiques de la malaria chez les oiseaux. Dans le but d'identifier les vecteurs naturels de malaria aviaire dans notre zone d'étude, nous avons tout d'abord collecté des moustiques sur le terrain, puis déterminé leur statut infectieux. Nous rapportons que les moustiques Culex pipiens sont principalement impliqués dans la transmission de Plasmodium vaughani au printemps, cette espèce de parasite étant progressivement remplacée par P. relictum au fil de la saison de transmission. Nous avons ensuite conduit une expérience visant à déterminer l'effet de la malaria aviaire sur des C. pipiens sauvages, naturellement infectés. Nous montrons que des coûts sont associés à l'infection pour les moustiques. Ces coûts occasionnent une diminution de la survie des vecteurs seulement lorsque ceux-ci sont privés de ressources nutritionnelles. Des changements saisonniers de climats pourraient affecter la quantité et la qualité des ressources disponibles pour les vecteurs et donc, leur aptitude à transmettre l'infection. Les traits comportementaux des moustiques vecteurs, tels que la recherche et le choix d'un hôte pour se nourrir, sont d'une importance majeure pour la dispersion de la malaria. Pour cela, nous avons offert à des C. pipiens sauvages l'opportunité de choisir simultanément entre une mésange charbonnière (Parus major) saine et une autre naturellement infectée. Nous montrons que les moustiques s'orientent préférentiellement vers des mésanges saines. Les Plasmodium aviaires exerceraient donc de fortes pressions de sélection sur leurs vecteurs, favorisant ainsi l'évolution de comportements d'évitement des parasites. Enfin nous avons cherché à identifier de potentiels liens entre symptômes de l'infection malarique chez les oiseaux et attractivité de ces derniers pour les moustiques. Nous montrons que des canaris (Serinus canaria) expérimentalement infectés sont fortement anémiés au moment du pic infectieux et que leur métabolisme basai diminue plus tard au cours de l'infection. Toutefois, aucun lien entre le statut infectieux et l'attractivité des canaris pour les moustiques n'a pu être montré lors d'une expérience réalisée en nature. Il se peut que ces liens aient été masqués par des facteurs environnementaux confondants. Dans son ensemble, cette thèse illustre que, contrairement aux idées reçues, les vecteurs de malaria aviaire ne sont pas toujours permissifs avec leurs parasites. L'environnement apparaît aussi comme un facteur déterminant dans la réponse des vecteurs face à la menace d'infection malarique. Cela pourrait fortement affecter l'épidémiologie de la malaria aviaire.

Insights into the biogeographical history of the Lower Guinea Forest Domain: evidence for the role of refugia in the intraspecific differentiation of Aucoumea klaineana.

Determining the biogeographical histories of rainforests is central to our understanding of the present distribution of tropical biodiversity. Ice age fragmentation of central African rainforests strongly influenced species distributions. Elevated areas characterized by higher species richness and endemism have been postulated to be Pleistocene forest refugia. However, it is often difficult to separate the effects of history and of present-day ecological conditions on diversity patterns at the interspecific level. Intraspecific genetic variation could yield new insights into history, because refugia hypotheses predict patterns not expected on the basis of contemporary environmental dynamics. Here, we test geographically explicit hypotheses of vicariance associated with the presence of putative refugia and provide clues about their location. We intensively sampled populations of Aucoumea klaineana, a forest tree sensitive to forest fragmentation, throughout its geographical range. Characterizing variation at 10 nuclear microsatellite loci, we were able to obtain phylogeographic data of unprecedented detail for this region. Using Bayesian clustering approaches, we demonstrated the presence of four differentiated genetic units. Their distribution matched that of forest refugia postulated from patterns of species richness and endemism. Our data also show differences in diversity dynamics at leading and trailing edges of the species' shifting distribution. Our results confirm predictions based on refugia hypotheses and cannot be explained on the basis of present-day ecological conditions.

An investigation of the nature and role of historicality in the thought of Dilthey and Heidegger

Introduction The question of the meaning, methods and philosophical manifestations of history is currently rife with contention. The problem that I will address in an exposition of the thought of Wilhelm Dilthey and Martin Heidegger, centers around the intersubjectivity of an historical world. Specifically, there are two interconnected issues. First, since all knowledge occurs to a person from within his or her historical age how can any person in any age make truth claims? In order to answer this concern we must understand the essence and role of history. Yet how can we come to an individual understanding ofwhat history is when the meanings that we use are themselves historically enveloped? But can we, we who are well aware of the knowledge that archaeology has dredged up from old texts or even from 'living' monuments of past ages, really neglect to notice these artifacts that exist within and enrich our world? Charges of wilful blindness would arise if any attempt were made to suggest that certain things of our world did not come down to us from the past. Thus it appears more important 2 to determine what this 'past' is and therefore how history operates than to simply derail the possibility for historical understanding. Wilhelm Dilthey, the great German historicist from the 19th century, did not question the existence of historical artifacts as from the past, but in treating knowledge as one such artifact placed the onus on knowledge to show itself as true, or meaningful, in light ofthe fact that other historical periods relied on different facts and generated different truths or meanings. The problem for him was not just determining what the role of history is, but moreover to discover how knowledge could make any claim as true knowledge. As he stated, there is a problem of "historical anarchy"!' Martin Heidegger picked up these two strands of Dilthey's thought and wanted to answer the problem of truth and meaning in order to solve the problem of historicism. This problem underscored, perhaps for the first time, that societal presuppositions about the past and present oftheir era are not immutable. Penetrating to the core of the raison d'etre of the age was an historical reflection about the past which was now conceived as separated both temporally and attitudinally from the present. But further than this, Heidegger's focus on asking the question of the meaning of Being meant that history must be ontologically explicated not merely ontically treated. Heidegger hopes to remove barriers to a genuine ontology by II 1 3 including history into an assessment ofprevious philosophical systems. He does this in order that the question of Being be more fully explicated, which necessarily for him includes the question of the Being of history. One approach to the question ofwhat history is, given the information that we get from historical knowledge, is whether such knowledge can be formalized into a science. Additionally, we can approach the question of what the essence and role of history is by revealing its underlying characteristics, that is, by focussing on historicality. Thus we will begin with an expository look at Dilthey's conception of history and historicality. We will then explore these issues first in Heidegger's Being and Time, then in the third chapter his middle and later works. Finally, we shall examine how Heidegger's conception may reflect a development in the conception of historicality over Dilthey's historicism, and what such a conception means for a contemporary historical understanding. The problem of existing in a common world which is perceived only individually has been philosophically addressed in many forms. Escaping a pure subjectivist interpretation of 'reality' has occupied Western thinkers not only in order to discover metaphysical truths, but also to provide a foundation for politics and ethics. Many thinkers accept a solipsistic view as inevitable and reject attempts at justifying truth in an intersubjective world. The problem ofhistoricality raises similar problems. We 4 -. - - - - exist in a common historical age, presumably, yet are only aware ofthe historicity of the age through our own individual thoughts. Thus the question arises, do we actually exist within a common history or do we merely individually interpret this as communal? What is the reality of history, individual or communal? Dilthey answers this question by asserting a 'reality' to the historical age thus overcoming solipsism by encasing individual human experience within the historical horizon of the age. This however does nothing to address the epistemological concern over the discoverablity of truth. Heidegger, on the other hand, rejects a metaphysical construel of history and seeks to ground history first within the ontology ofDasein, and second, within the so called "sending" of Being. Thus there can be no solipsism for Heidegger because Dasein's Being is necessarily "cohistorical", Being-with-Others, and furthermore, this historical-Being-in-the-worldwith- Others is the horizon of Being over which truth can appear. Heidegger's solution to the problem of solipsism appears to satisfy that the world is not just a subjective idealist creation and also that one need not appeal to any universal measures of truth or presumed eternal verities. Thus in elucidating Heidegger's notion of history I will also confront the issues ofDasein's Being-alongside-things as well as the Being of Dasein as Being-in-the-world so that Dasein's historicality is explicated vis-a-vis the "sending of Being" (die Schicken des S eins).

History and Theorizing: The Case of Winemaking in the Ontario Wine Industry

Despite the fact that theorization has been established as an important social mechanism in a variety of contexts, little research has explicated how this process works. I argue that theorization entails strategic constructions of history, or rhetorical history, in order to persuade audiences of legitimacy. I examine the role that history plays in actors’ theorizations of the Ontario wine industry as world class. By conducting a rhetorical analysis of the newsletters and websites of Ontario wineries, I find that various themes of history are routinely employed to re-theorize the industry as one that produces world class wines. In general, the findings suggest that the narratives of Ontario wineries tap into global repertoires of fine wine to portray the continuity of current practices with those of Old World winemaking. In addition, wineries sometimes tap into local histories to convey a sense of uniqueness, but they also obscure the history of poor winemaking in the region.

Scriptural Archeology: Excavating the Presence of Women in the Torah

Women's roles in religious history have been traditionally described in terms of their relation and value to men. The normative religious texts provide an androcentric perspective on the gender relationships within the early community, the growth of Judaism in "Jacob's House" and the monotheistic worship of God. Yet these literary representations omit an entire half of the experience of the Jewish community: the perspective and participation of women. As Judith Plaskow argues extensively in Standing Again at Sinai, women are defined not in her own terms or in her own voice, but by her relationship and value to men through the androcentric vocabulary of the Torah. This statement is textually illustrated by the authorial and editorial presentation of women and their place in ancient Israelite society in the Torah. As Judaism grew increasingly androcentric in its leadership, women were increasingly reduced to marginal figures in the community by authorial and editorial revisions. Yet the participation of women of ancient Israel is not lost. Instead, the presence of women is buried beneath the androcentric presentation of the early Judaic community, waiting to be excavated by historical and scriptural examination. The retelling of the past is influenced by the present; memory is not static but takes on different shapes depending on the focus of concentration. However, tradition greatly influences the interpretation of religious history as well. In the book of Genesis, the literature emphasizes the divine appointment of male figures such as Abraham the father of the covenant and Jacob who is renamed and claimed by God as "Israel," placing them at the center of Jewish history. As a result, the other figures in these biblical narratives are described in relation to the patriarchs, those male bearers of the covenant, by their service or their value to him. Women are at the bottom of this hierarchy. Although female figures of exceptional quality are noted in later chronicles, such as Ruth, Deborah and Miriam, it is the very nature of their exception that highlights the androcentric editorial focus of the Torah. I agree with Peggy Day, whose own scriptural examination in Gender and Difference in Ancient Israel, makes the important distinction between the literary representation and the reality of ancient Israelite culture: they are not coextensive nor equivalent. Although the text represents the culture of ancient Israel as male dominated from the time of Abraham, this presentation omits the perspective of half of the population-the women. By beginning at the point of realization that women did exist and were active in their culture, and placing aside the androcentric perspective of the text and its editors, the reality of women's place in ancient Israel may be determined. Through this new perspective, the women of the Torah will emerge as the archetypes of strength, leadership and spiritual insight to provide Jewish women of the present with female, ancestral role models and a foundation for their gender's heritage, a more complete understanding of the partial record of Jewish history recorded in the Torah. Those stories that appear as the exception of women's presence will unveil an exceptional presence. As Tamar Frankiel eloquently states in The Voice of Sarah, "the women we call our 'Mothers'-Sarah, Rivkah (Rebekah), Rachel, and Leah-are not merely mothers, any more than the 'Fathers'-Abraham, Isaac and Jacob-are merely fathers "(Frankiel 5).

History and Epistemology of Science in the Classroom: The Synthesis of Quinine as a Proposal

The history of the quinine synthesis can be used as a case study to emphasize that science is influenced by social and historical processes. The first efforts toward the synthesis of this substance, which until recently was the only treatment for malaria, were by Perkin in 1856 when, trying to obtain quinine,,. he synthesized mauveine. Since then, the quest for the total synthesis of quinine involved several characters in a web of controversies. A major step in this process was made in 1918 by Rabe and Kindler, who proposed the synthesis of quinine from quinotoxine. Twenty-six years later, after obtaining the total synthesis of quinotoxine, Woodward and Doering announced the total synthesis of quinine. However, the lack of experimental details about Rabe and Kindler's process, associated with Woodward and Doering's failure to reproduce it, raised a series of doubts about the synthesis. Stork and colleagues questioned the veracity of the experimental data and even the scientific reputation of the involved researchers. Doubts remained alive until 2008, when Williams and Smith reported, not without reservations, the reproducibility of Rabe and Kindler's protocol. The scientific knowledge as a social and historical development, its legitimating process, and the absence of neutrality in science constitute aspects that can be discussed from this case study, providing significant contributions to science education, in particular, to the initial or continued training of chemistry teachers.

Ogawa Mimei's Children's Stories: A Case Study of the Rise of Childhood in the Context of Westernization and Japanese Modernization

In this thesis, I examine the influences of westernization, the tension between Japanese modernity and tradition, and the stories of Hans Christian Andersen on Ogawa Mimei’s children’s stories. I begin the body of my thesis with a brief historical background of Japan, beginning with the start of the Meiji period in 1868. Within the historical section, I focus on societal and cultural elements and changes that pertain to my thesis. I also include the introduction of Hans Christian Andersen in Japan. I wrap up the historical section by a description of Ogawa’s involvement in the Japanese proletarian literature movement and the rise of the Japanese proletarian children’s literature movement. Then, I launch into an analysis of Ogawa’s works categorized by thematic elements. These elements include westernization, class conflict, nature and civilization, religion and morals, and children and childhood. When relevant, I also compare and contrast Ogawa’s stories with Andersen’s. In the westernization section, I show how some of Ogawa’s stories demonstrate contact between Japan and the West. In the Class Conflict section, I discuss how Ogawa views class through a socialist lens, whereas Andersen does not dispute class distinctions, but encourages his readers to attempt an upward social climb. In the nature and civilization section, I show how Ogawa and Andersen share common opinions on the impact of civilization on nature. In the religion and morals section, I show how Ogawa incorporates religion, including Christianity, into vii his works. Andersen utilizes religion in a more overt manner in order to convey morals to his audience. Both authors address religious topics like the concept of the afterlife. Finally, in children and childhood, I demonstrate how both Ogawa and Andersen treat their child protagonists and use them and their situations to instruct their readers. Through this case study, I show how westernization and the tensions between Japanese modernization and tradition led to the rise of the proletarian children’s literature movement, which is exemplified by Ogawa’s stories. The emergence of the proletarian children’s literature movement is an indication of the establishment of a new concept of childhood in Japan. Writers like Ogawa Mimei attempted to write children’s stories that represented the new Japanese culture that was a result of adapting Western ideals to fit Japanese society. Some of Ogawa’s stories are a direct commentary on his opinion of Japanese interaction with the West. By comparing Ogawa’s and Andersen’s stories, I demonstrate how Ogawa borrows certain Western elements and possibly responds directly to Andersen. Ogawa also addresses some of the same topics as Andersen, yet their reactions are not always the same. What I find in my analysis supports my thesis that Ogawa is able to maintain Japanese tradition while infusing his children’s stories with Western and modern elements. In doing so, he reflects a largely popular social and cultural practice of his time.

The Role of Cortisol in the Cycle of Violence

Child abuse and neglect are universal risk factors for delinquency, violence and aggression; this phenomenon is known as the cycle of violence. Despite a wide body of research demonstrating this phenomenon, the processes which mediate this relationship remain largely unknown. One potentially relevant result of abuse and neglect may be disruptions in the development of the body’s stress response, specifically the function of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA-axis, and its end-product, cortisol, may play a role in regulating aggressive behavior, but this function may be disrupted following abuse and neglect. Another risk factor for aggression, psychopathy, may mediate the cycle of violence or independently contribute to aggressive behavior. This study examined the relationship between child abuse and neglect, HPA-axis function, psychopathy and aggression. History of abuse was measured using a self-report questionnaire, the Childhood Trauma Questionnaire. Using a within-subject, placebo-controlled, counter-balanced dosing design, 67 adults were given an acute dose of 20mg cortisol as a challenge to the HPA-axis. Following dosing, measures of cortisol response were obtained through saliva samples, and state-aggressive behavior was measured by a laboratory task, the Point-Subtraction Aggression Paradigm (PSAP). Basal measures of cortisol were obtained prior to dosing. Psychopathy and a trait-measure of aggression were assessed through self-report questionnaires. PSAP data and trait-aggression scores were normalized and summed for an overall aggression score. Linear regression analyses indicated that a history of abuse and neglect robustly predicted aggression, supporting the cycle of violence hypothesis. Further, abuse and neglect predicted a diminished HPA-axis response to the cortisol challenge. Although a diminished HPA-axis response significantly predicted increased aggression, mediation analysis revealed that HPA-axis reactivity did not mediate a significant portion of the effect of abuse and neglect on aggression. However, HPA-axis reactivity did mediate part of the effect, indicating that HPA-axis function may be a factor in the cycle of violence. Psychopathy robustly predicted increased aggression. Although the results indicate that cortisol, psychopathy and HPA-axis function are involved in the cycle of violence, further research is required to better understand the complex interaction of these factors.

The Lord of Heaven in the Inner Chambers: Jesuits, Women, and Domestic Christianity (ca. 1580-1690)

The study focuses on gender norms and practices in Chinese Christian communities established by Jesuit missionary activity during the long seventeenth century. It analyzes how European and Chinese gender norms and practices affected each other in the context of the Sino-Western cultural contact initiated by the missionaries. The thesis consists of two parts. First, it analyzes the ways in which European Jesuits engaged with Chinese gender relations in the course of their mission in China. The study demonstrates that the Jesuits’ adoption of the Chinese scholar-gentry’s habitus entailed a partial adaptation to Confucian gender norms. The latter placed great emphasis on gender segregation and therefore discouraged direct communication between missionaries and Chinese women. This resulted in the emergence of organizational and devotional arrangements of Christian communities specific to China. Second, the study discusses Chinese Christian women's religious culture that emerged in the absence of a strong missionary presence among female devotees. It points out that Chinese Christian women created their own ritual culture and religious sociability in the domestic context, and that they actively took part in shaping Chinese Christianity as masters of domestic rituals.

Early Life History and a Modeling Framework for Lobster (Homarus Americanus) Populations in the Gulf of Maine

Beginning in the late 1980s, lobster (Homarus americanus) landings for the state of Maine and the Bay of Fundy increased to levels more than three times their previous 20-year means. Reduced predation may have permitted the expansion of lobsters into previously inhospitable territory, but we argue that in this region the spatial patterns of recruitment and the abundance of lobsters are substantially driven by events governing the earliest life history stages, including the abundance and distribution of planktonic stages and their initial settlement as Young-of-Year (YOY) lobsters. Settlement densities appear to be strongly driven by abundance of the pelagic postlarvae. Postlarvae and YOY show large-scale spatial patterns commensurate with coastal circulation, but also multi-year trends in abundance and abrupt shifts in abundance and spatial patterns that signal strong environmental forcing. The extent of the coastal shelf that defines the initial settlement grounds for lobsters is important to future population modeling. We address one part of this definition by examining patterns of settlement with depth, and discuss a modeling framework for the full life history of lobsters in the Gulf of Maine.
