Therapists’ perceptions of the therapeutic alliance in “Mandatory” therapy with sex offenders
Research suggests that the therapeutic alliance (TA) plays an important part in successful therapy. The pantheoretical concept of the alliance (Bordin, 1979) assumes a client seeks to make a change and joins the therapist in a willing journey. However, treatment with sex offenders can entail various levels of coercion. Little is known about the process of the TA in therapy with sex offenders whose therapy could be seen as coerced or mandated. Thus, the aim of this research was to explore therapists’ perceptions of the TA with sex offenders whose therapy could be seen as “mandated” because it was part of their plan for release/rehabilitation. Eleven therapists were interviewed about their experiences and a qualitative thematic analysis elicited five themes: dynamics of forced work, explicit terms of working, persuasive encouragement to engage, connecting with the human element and preservation and protection. Implications for practice are discussed alongside recommendations for future research
NKG7 enhances CD8+ T cell synapse efficiency to limit inflammation
Cytotoxic lymphocytes are essential for anti-tumor immunity, and for effective responses to cancer immunotherapy. Natural killer cell granule protein 7 (NKG7) is expressed at high levels in cytotoxic lymphocytes infiltrating tumors from patients treated with immunotherapy, but until recently, the role of this protein in cytotoxic lymphocyte function was largely unknown. Unexpectedly, we found that highly CD8+ T cell-immunogenic murine colon carcinoma (MC38-OVA) tumors grew at an equal rate in Nkg7+/+ and Nkg7-/- littermate mice, suggesting NKG7 may not be necessary for effective CD8+ T cell anti-tumor activity. Mechanistically, we found that deletion of NKG7 reduces the ability of CD8+ T cells to degranulate and kill target cells in vitro. However, as a result of inefficient cytotoxic activity, NKG7 deficient T cells form a prolonged immune synapse with tumor cells, resulting in increased secretion of inflammatory cytokines, including tumor necrosis factor alpha (TNF). By deleting the TNF receptor, TNFR1, from MC38-OVA tumors, we demonstrate that this hyper-secretion of TNF compensates for reduced synapse-mediated cytotoxic activity against MC38-OVA tumors in vivo, via increased TNF-mediated tumor cell death. Taken together, our results demonstrate that NKG7 enhances CD8+ T cell immune synapse efficiency, which may serve as a mechanism to accelerate direct cytotoxicity and limit potentially harmful inflammatory responses
Rapid Discovery and Structure-Activity Relationships of Pyrazolopyrimidines that Potently Suppress Breast Cancer Cell Growth via SRC Kinase Inhibition with Exceptional Selectivity over ABL Kinase
Novel
pyrazolopyrimidines displaying high potency and selectivity
toward SRC family kinases have been developed by combining ligand-based
design and phenotypic screening in an iterative manner. Compounds
were derived from the promiscuous kinase inhibitor PP1 to search for
analogs that could potentially target a broad spectrum of kinases
involved in cancer. Phenotypic screening against MCF7 mammary adenocarcinoma
cells generated target-agnostic structure–activity relationships
that biased subsequent designs toward breast cancer treatment rather
than to a particular target. This strategy led to the discovery of
two potent antiproliferative leads with phenotypically distinct anticancer
mode of actions. Kinase profiling and further optimization resulted
in eCF506, the first small molecule with subnanomolar IC<sub>50</sub> for SRC that requires 3 orders of magnitude greater concentration
to inhibit ABL. eCF506 exhibits excellent water solubility, an optimal
DMPK profile and oral bioavailability, halts SRC-associated neuromast
migration in zebrafish embryos without inducing life-threatening heart
defects, and inhibits SRC phosphorylation in tumor xenografts in mice
Child Health Partnerships: a review of program characteristics, outcomes and their relationship
<p>Abstract</p> <p>Background</p> <p>Novel approaches are increasingly employed to address the social determinants of health of children world-wide. Such approaches have included complex social programs involving multiple stakeholders from different sectors jointly working together (hereafter Child Health Partnerships). Previous reviews have questioned whether these programs have led to significant improvements in child health and related outcomes. We aim to provide definitive answers to this question as well as identifying the characteristics of successful partnerships.</p> <p>Methods</p> <p>A comprehensive literature search identified 11 major Child Health Partnerships in four comparable developed countries. A critical review is focused on various aspects of these including their target groups, program mechanics and outcomes.</p> <p>Results and Conclusions</p> <p>There was evidence of success in several major areas from the formation of effective joint operations of partners in different partnership models to improvement in both child wellbeing and parenting. There is emerging evidence that Child Health Partnerships are cost-effective. Population characteristics and local contexts need to be taken into account in the introduction and implementation of these programs.</p
Access to housing subsidies, housing status, drug use and HIV risk among low-income U.S. urban residents
<p>Abstract</p> <p>Background</p> <p>Much research has shown an association between homelessness and unstable housing and HIV risk but most has relied on relatively narrow definitions of housing status that preclude a deeper understanding of this relationship. Fewer studies have examined access to housing subsidies and supportive housing programs among low-income populations with different personal characteristics. This paper explores personal characteristics associated with access to housing subsidies and supportive housing, the relationship between personal characteristics and housing status, and the relationship between housing status and sexual risk behaviors among low-income urban residents.</p> <p>Methods</p> <p>Surveys were conducted with 392 low-income residents from Hartford and East Harford, Connecticut through a targeted sampling plan. We measured personal characteristics (income, education, use of crack, heroin, or cocaine in the last 6 months, receipt of welfare benefits, mental illness diagnosis, arrest, criminal conviction, longest prison term served, and self-reported HIV diagnosis); access to housing subsidies or supportive housing programs; current housing status; and sexual risk behaviors. To answer the aims above, we performed univariate analyses using Chi-square or 2-sided ANOVA's. Those with significance levels above (0.10) were included in multivariate analyses. We performed 2 separate multiple regressions to determine the effects of personal characteristics on access to housing subsidies and access to supportive housing respectively. We used multinomial main effects logistic regression to determine the effects of housing status on sexual risk behavior.</p> <p>Results</p> <p>Being HIV positive or having a mental illness predicted access to housing subsidies and supportive housing, while having a criminal conviction was not related to access to either housing subsidies or supportive housing. Drug use was associated with poorer housing statuses such as living on the street or in a shelter, or temporarily doubling up with friends, acquaintances or sex partners. Living with friends, acquaintances or sex partners was associated with greater sexual risk than those living on the street or in other stable housing situations.</p> <p>Conclusions</p> <p>Results suggest that providing low-income and supportive housing may be an effective structural HIV prevention intervention, but that the availability and accessibility of these programs must be increased.</p
Anatomical Specializations for Nocturnality in a Critically Endangered Parrot, the Kakapo (Strigops habroptilus)
The shift from a diurnal to nocturnal lifestyle in vertebrates is generally associated with either enhanced visual sensitivity or a decreased reliance on vision. Within birds, most studies have focused on differences in the visual system across all birds with respect to nocturnality-diurnality. The critically endangered Kakapo (Strigops habroptilus), a parrot endemic to New Zealand, is an example of a species that has evolved a nocturnal lifestyle in an otherwise diurnal lineage, but nothing is known about its' visual system. Here, we provide a detailed morphological analysis of the orbits, brain, eye, and retina of the Kakapo and comparisons with other birds. Morphometric analyses revealed that the Kakapo's orbits are significantly more convergent than other parrots, suggesting an increased binocular overlap in the visual field. The Kakapo exhibits an eye shape that is consistent with other nocturnal birds, including owls and nightjars, but is also within the range of the diurnal parrots. With respect to the brain, the Kakapo has a significantly smaller optic nerve and tectofugal visual pathway. Specifically, the optic tectum, nucleus rotundus and entopallium were significantly reduced in relative size compared to other parrots. There was no apparent reduction to the thalamofugal visual pathway. Finally, the retinal morphology of the Kakapo is similar to that of both diurnal and nocturnal birds, suggesting a retina that is specialised for a crepuscular niche. Overall, this suggests that the Kakapo has enhanced light sensitivity, poor visual acuity and a larger binocular field than other parrots. We conclude that the Kakapo possesses a visual system unlike that of either strictly nocturnal or diurnal birds and therefore does not adhere to the traditional view of the evolution of nocturnality in birds
‘A Girl's Love’: Lord Alfred Douglas as Homoerotic Muse in the Poetry of Olive Custance
This is an Accepted Manuscript of an article published by Taylor & Francis in Women: a Cultural Review on 15/09/2011, available online: http://dx.doi.org/10.1080/09574042.2011.585045.This article explores the relationship between the poet Olive Custance and her husband Lord Alfred Douglas, arguing that Custance constructed Douglas as a male muse figure in her poetry, particularly the sequence ‘Songs of a Fairy Princess’ (Rainbows 1902). The introduction sets out Custance's problematic historical positioning as a ‘decadent’ poet who published nothing following the Great War, but whose work came too late to fit into strictly ‘fin de siècle’ categories. I suggest, however, that Custance's oscillating constructions of gender and sexuality make her more relevant to the concerns of modernity than has previously been acknowledged and her work anticipates what is now termed ‘queer’. The first main section of the article traces the cultural background of the fin de siècle male muse, arguing that Custance's key influences—male homoerotic writers such as Wilde and Pater—meant it was logical that she should imagine the muse as male, despite the problems associated with gender-reversals of the muse-poet relationship which have been identified by several feminist critics. I then move on to focus specifically on how Shakespearean discourses of gender performance and cross-dressing played a key role in Custance and Douglas's courtship, as they exchanged the fluid roles of ‘Prince’, ‘Princess’ and ‘Page’. The penultimate section of the article focuses on discourses of fairy tale and fantasia in Custance's ‘Songs of a Fairy Princess’ sequence, in which these fantasy roles contribute to a construction of Douglas as a feminised object, and the relationship between the ‘Prince’ and ‘Princess’ is described in terms of narcissistic sameness. My paper concludes by tracing the demise of Custance and Douglas's relationship; as Douglas attempted to be more ‘manly’, he sought to escape the role of object, resulting in Custance losing her male muse. But her sexually-dissident constructions of the male muse remain important experiments worthy of critical attention
An organizational impression management perspective on the formation of corporate reputations
Researchers have only recently turned their attention to the study of corporate reputation. As is characteristic of many early areas of management inquiry, the field is decidedly multidisciplinary and disconnected. This article selectively reviews reputation research conducted mainly during the past decade. A framework is proposed that views reputation from the perspective of organizational impression management. Corporations are viewed as social actors, intent on enhancing their respectability and impressiveness in the eyes of constituents
