The Grassroots Home: How Local Communities Are Fighting Homelessness

In the 1980s federal policy combined with market forces to produce the American tragedy of homelessness. Since that time influential policymakers have debated every aspect of the issue, but avoided the large-scale commitment needed for solutions. Locally, however, grassroots efforts have made these commitments and forged the coalitions needed to address the issue. The solution to homelessness lies in harnessing these same successful public and private resources on the regional and national levels

The Influence of Media Type on Sexually Impositional Behavior

Sexual aggression and rape are pervasive and serious problems in the United States. One factor which has been associated with sexual aggression and rape is the perpetrator\u27s use of sexually explicit material, especially sexually violent pornography. The current study examined the effect of exposure to different types of media depictions, including sexually violent, violent, sexual, and general arousing conditions on men\u27s expression of sexually impositional behavior toward women using a laboratory analogue. Participants viewed one of four, 45 minute clips from the above categories. Then, they chose one of four short clips (negatively arousing, sexual clip; a negatively arousing, nonsexual clip; a positively arousing, sexual clip; or a positively arousing, nonsexual clip) to show to a female confederate. Following this clip, they showed each of the four clips to the female confederate for a length which they determined. Logistic regression analyses do not support the hypothesis that exposure to 45 minutes of a single instance of a particular media type affects clip choice. Multiple regression analyses find no significant effect of media type exposure on clip length. Thus, the current study does not provide support for the hypothesis that exposure to sexually violent media affects sexually impositional behavior in men. However, the current study does provide support for the validity of this analogue while also suggesting directions for continued refinement of the procedure

Neuroscience Informed Prolonged Exposure Practice: Increasing Efficiency and Efficacy Through Mechanisms

Prolonged exposure (PE) is an empirically supported efficacious treatment for posttraumatic stress disorder (PTSD). In this focused review, we briefly review the neurobiological networks in PTSD relevant to PE, discuss the theoretical basis of PE, review the neurobiological mechanisms underlying the effectiveness of PE and identify the enhancements that can be applied to increase treatment response and retention. Based on the reviewed studies, it is clear that PTSD results in disrupted network of interconnected regions, and PE has been shown to increase the connectivity within and between these regions. Successful extinction recall in PE is related to increased functional coherence between the ventromedial prefrontal cortex (vmPFC), amygdala and the hippocampus. Increased connectivity within the dorsolateral PFC (dlPFC) following PE is associated with more effective downregulation of emotional responses in stressful situations. Pre-existing neural connectivity also in some cases predicts response to exposure treatment. We consider various enhancements that have been used with PE, including serotonin reuptake inhibitors (SSRIs), D-cycloserine (DCS), allopregnanolone (ALLO) and propranolol, repetitive transcranial magnetic stimulation (rTMS), oxytocin and MDMA. Given that neural connectivity appears to be crucial in mechanisms of action of PE, rTMS is a logical target for further research as an enhancement of PE. Additionally, exploring the effectiveness and mechanisms of action of oxytocin and MDMA in conjunction with PE may lead to improvement in treatment engagement and retention

PTSD and Pain: Exploring the Impact of Posttraumatic Cognitions in Veterans Seeking Treatment for PTSD

Objective Previous research has demonstrated a significant relationship between posttraumatic stress disorder ( PTSD ) and pain. While several models attempt to explain this relationship, significant questions remain regarding factors that may play a role in this interaction. The purpose of this study was to determine whether posttraumatic cognitions mediate the relationship between PTSD and pain. Design The sample comprised 136 veterans who presented to the VA A nn A rbor H ealth C are System seeking evaluation and treatment in the PTSD clinic. Participants completed the Clinician‐Administered PTSD Scale, the Posttraumatic Cognitions Inventory, and Brief Pain Inventory‐Short Form, along with other assessments as part of their evaluation. Results This study showed that the majority of patients (86.8%) reported some problems with pain. Further, the findings indicate that there is a significant relationship between PTSD severity and pain severity. Posttraumatic cognitions were not related to the level of pain experienced, but they were related to pain interference in this population. Conclusions In particular, negative cognitions regarding the self were associated with the level of pain‐related interference, and partially mediated the relationship between PTSD and pain. The clinical implications of these findings are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/101855/1/pme12260.pd

Medium range structural order in amorphous tantala spatially resolved with changes to atomic structure by thermal annealing

Amorphous tantala (a-Ta2O5) is an important technological material that has wide ranging applications in electronics, optics and the biomedical industry. It is used as the high refractive index layers in the multi-layer dielectric mirror coatings in the latest generation of gravitational wave interferometers, as well as other precision interferometers. One of the current limitations in sensitivity of gravitational wave detectors is Brownian thermal noise that arises from the tantala mirror coatings. Measurements have shown differences in mechanical loss of the mirror coatings, which is directly related to Brownian thermal noise, in response to thermal annealing. We utilise scanning electron diffraction to perform Fluctuation Electron Microscopy (FEM) on Ion Beam Sputtered (IBS) amorphous tantala coatings, definitively showing an increase in the medium range order (MRO), as determined from the variance between the diffraction patterns in the scan, due to thermal annealing at increasing temperatures. Moreover, we employ Virtual Dark-Field Imaging (VDFi) to spatially resolve the FEM signal, enabling investigation of the persistence of the fragments responsible for the medium range order, as well as the extent of the ordering over nm length scales, and show ordered patches larger than 5 nm in the highest temperature annealed sample. These structural changes directly correlate with the observed changes in mechanical loss.Comment: 22 pages, 5 figure

Preparing Women In Academic Psychology for Their First Compensation Negotiation: A Panel Perspective of Challenges & Future Recommendations

Successfully landing and then negotiating for your first position is an exciting and challenging task. In this paper, we use a narrative review to present the literature on gender and negotiation with a focus on academic psychology work contexts. We highlight important differences between factors that are within the individual’s control vs. factors at the institutional or societal level. Drawing directly from the research literature, we make several recommendations for women trying to manage negotiation in contexts that are likely biased against them at the institutional and cultural level. For example, we recommend that women take steps to reduce situational ambiguity, use niceness and assertion strategically, and cognitive re-framing to improve performance. We also make parallel recommendations for institutions, to create a more equal playing field in employment negotiations in academia. We conclude with expert advice on how to manage the important task of negotiation throughout the career from successful psychologists to contextualize the research findings at the personal level
