The risk of telling : a dyadic perspective on romantic partners' responses to child sexual abuse disclosure and their associations with sexual and relationship satisfaction
Essai prĂ©sentĂ© Ă la FacultĂ© des arts et des sciences en vue de l'obtention du grade de Doctorat en psychologie clinique (D. Psy.)Les survivants dâagression sexuelle Ă lâenfance (ASE) doivent souvent composer avec les consĂ©quences Ă long terme de ce trauma. Toutefois, il existe une grande variabilitĂ© quant aux impacts individuels de lâASE. Certains auteurs croient que la rĂ©ponse obtenue lors du dĂ©voilement de lâASE aux proches du survivant, pourrait ĂȘtre lâun des dĂ©terminants de cette variabilitĂ©. Cependant, le dĂ©voilement Ă lâĂąge adulte, notamment au partenaire amoureux, a Ă©tĂ© peu Ă©tudiĂ©. La prĂ©sente Ă©tude examine les associations entre les rĂ©ponses des partenaires amoureux au dĂ©voilement, tels que perçues par les survivants, ainsi que la satisfaction sexuelle et conjugale des deux membres du couple, auprĂšs dâun Ă©chantillon de 70 couples de la communautĂ© ayant rapportĂ© une ASE et lâayant dĂ©voilĂ©e Ă leur partenaire. Les participants ont complĂ©tĂ© des questionnaires auto-rapportĂ©s en ligne. Les rĂ©sultats dâanalyses de trajectoire au sein dâun modĂšle « Actor-Partner Interdependence Model » (APIM) indiquent que les rĂ©ponses de « soutien Ă©motionnel » de la part des partenaires durant le dĂ©voilement, telles que perçues par les survivants, Ă©taient positivement associĂ©es Ă leur propre satisfaction sexuelle ainsi quâĂ celle de leur partenaire. Les rĂ©ponses de « stigmatisation/se sentir traitĂ© diffĂ©remment » de la part des partenaires, telles que perçues par les survivants, Ă©taient associĂ©es Ă une moins bonne satisfaction conjugale, Ă la fois pour les survivants et leurs partenaires. Les rĂ©sultats suggĂšrent que les rĂ©ponses des partenaires au dĂ©voilement dâune ASE, tels que perçues par les survivants, peuvent avoir un impact positif autant que nĂ©gatif sur la satisfaction conjugale et sexuelle des deux partenaires.Survivors of childhood sexual abuse (CSA) often experience adverse trauma-related long term consequences, which vary widely among survivors. Some authors argued that this variability might be explained in part by the response of others to survivorsâ disclosure of the CSA. However, disclosure during adulthood has received little empirical attention, in particular, disclosure to a romantic partner. Among 70 community couples who reported CSA and disclosure to their partner, this study examined associations between survivorsâ perception of partner responses to their disclosure, and both partnersâ sexual and relationship satisfaction. Participants completed self-report questionnaires online. Results of path analyses within an actor-partner interdependence model indicated that survivorsâ perceived partner responses of emotional support to disclosure were associated with their own and their partners' higher sexual satisfaction. Survivorsâ perceived responses of being stigmatized/treated differently by the partner were associated with their own and their partnersâ poorer relationship satisfaction. Findings suggest that survivor-perceived partner responses to the disclosure of CSA can have both a positive and a negative impact on the sexual and relationship satisfaction of both partners
Thermodynamic analysis of the Quantum Critical behavior of Ce-lattice compounds
A systematic analysis of low temperature magnetic phase diagrams of Ce
compounds is performed in order to recognize the thermodynamic conditions to be
fulfilled by those systems to reach a quantum critical regime and,
alternatively, to identify other kinds of low temperature behaviors. Based on
specific heat () and entropy () results, three different types of
phase diagrams are recognized: i) with the entropy involved into the ordered
phase () decreasing proportionally to the ordering temperature
(), ii) those showing a transference of degrees of freedom from the
ordered phase to a non-magnetic component, with their jump
() vanishing at finite temperature, and iii) those ending in a
critical point at finite temperature because their do not decrease
with producing an entropy accumulation at low temperature.
Only those systems belonging to the first case, i.e. with as
, can be regarded as candidates for quantum critical behavior.
Their magnetic phase boundaries deviate from the classical negative curvature
below \,K, denouncing frequent misleading extrapolations down to
T=0. Different characteristic concentrations are recognized and analyzed for
Ce-ligand alloyed systems. Particularly, a pre-critical region is identified,
where the nature of the magnetic transition undergoes significant
modifications, with its discontinuity strongly
affected by magnetic field and showing an increasing remnant entropy at . Physical constraints arising from the third law at are discussed
and recognized from experimental results
Obesity and the Rate of Time Preference: Is there a Connection?
We hypothesize that recent trends in U.S. and worldwide obesity are, in part, related to an increase in the marginal rate of time preference, where time preference refers to the rate at which people are willing to trade current benefit for future benefit. The higher the rate of time preference, the larger is the factor by which individuals discount the future health risks associated with current consumption. Data from the United States, as well as international evidence, suggests that a relationship between these two variables is plausible. We encourage researchers to explore the possible link between obesity and time preference, as important insights are likely to result
The prototype colliding-wind pinwheel WR 104
Results from the most extensive study of the time-evolving dust structure
around the prototype "Pinwheel" nebula WR 104 are presented. Encompassing 11
epochs in three near-infrared filter bandpasses, a homogeneous imaging data set
spanning more than 6 years (or 10 orbits) is presented. Data were obtained from
the highly successful Keck Aperture Masking Experiment, which can recover high
fidelity images at extremely high angular resolutions, revealing the geometry
of the plume with unprecedented precision. Inferred properties for the
(unresolved) underlying binary and wind system are orbital period 241.5 +/- 0.5
days and angular outflow velocity of 0.28 +/- 0.02 mas/day. An optically thin
cavity of angular size 13.3 +/- 1.4 mas was found to lie between the central
binary and the onset of the spiral dust plume. Rotational motion of the wind
system induced by the binary orbit is found to have important ramifications:
entanglement of the winds results in strong shock activity far downstream from
the nose of the bowshock. The far greater fraction of the winds participating
in the collision may play a key role in gas compression and the nucleation of
dust at large radii from the central binary and shock stagnation point.
Investigation of the effects of radiative braking pointed towards significant
modifications of the simple hydrostatic colliding wind geometry, extending the
relevance of this phenomena to wider binary systems than previously considered.
Limits placed on the maximum allowed orbital eccentricity of e < 0.06 argue
strongly for a prehistory of tidal circularization in this system. Finally we
discuss the implications of Earth's polar (i < 16 deg) vantage point onto a
system likely to host supernova explosions at future epochs.Comment: 35 pages, 8 figures, Accepted for publication in Astrophysical

The effectiveness of public health interventions to reduce the health impact of climate change:a systematic review of systematic reviews
Climate change is likely to be one of the most important threats to public health in the coming years. Yet despite the large number of papers considering the health impact of climate change, few have considered what public health interventions may be of most value in reducing the disease burden. We aimed to evaluate the effectiveness of public health interventions to reduce the disease burden of high priority climate sensitive diseases
Habitat determinants of goldenâheaded lion tamarin (Leontopithecus chrysomelas) occupancy of cacao agroforests: Gloomy conservation prospects for management intensification
Organismal distributions in humanâmodified landscapes largely depend on the capacity of any given species to adapt to changes in habitat structure and quality. The goldenâheaded lion tamarin (GHLT; Leontopithecus chrysomelas) is an Endangered primate from the Brazilian Atlantic Forest whose remaining populations occupy heterogeneous landscapes consisting primarily of shade cacao (Theobroma cacao) agroforestry, locally known as cabrucas. This cash crop can coexist with high densities of native tree species and holds a significant proportion of the native fauna, but its widely extolled wildlifeâfriendly status is increasingly threatened by management intensification. Although this potentially threatens to reduce the distribution of GHLTs, the main determinants of tamarin's occupancy of cabrucas remain unknown, thereby limiting our ability to design and implement appropriate conservation practices. We surveyed 16 cabruca patches in southern Bahia, Brazil, and used occupancy modeling to identify the best predictors of GHLT patch occupancy. Key explanatory variables included vegetation structure, critical resources, landscape context, human disturbance, and predation pressure. We found a negative relationship between GHLT occupancy and the prevalence of jackfruit trees (Artocarpus heterophylus), which is likely associated with the low representation of other key food species for GHLTs. Conversely, cabrucas retaining largeâdiameter canopy trees have a higher probability of GHLT occupancy, likely because these trees provide preferred sleeping sites. Thus, key large tree resources (food and shelter) are currently the main drivers of GHLT occupancy within cabruca agroecosystems. Since both factors can be directly affected by crop management practices, intensification of cabrucas may induce significant habitat impacts on GHLT populations over much of their remaining rangeâwide distribution
Metallothionein genes: no association with Crohn's disease in a New Zealand population
Metallothioneins (MTs) are excellent candidate genes for Inflammatory Bowel Disease (IBD) and have previously been shown to have altered expression in both animal and human studies of IBD. This is the first study to examine genetic variants within the MT genes and aims to determine whether such genetic variants have an important role in this disease. 28 tag SNPs in genes MT1 (subtypes A, B, E, F, G, H, M, X), MT2, MT3 and MT4 were selected for genotyping in a well-characterized New Zealand dataset consisting of 406 patients with Crohn's Disease and 638 controls. We did not find any evidence of association for MT genetic variation with CD. The lack of association indicates that genetic variants in the MT genes do not play a significant role in predisposing to CD in the New Zealand population
