Spitzer Imaging of Herschel-ATLAS Gravitationally Lensed Submillimeter Sources

We present physical properties of two submillimeter selected gravitationally lensed sources, identified in the Herschel Astrophysical Terahertz Large Area Survey. These submillimeter galaxies (SMGs) have flux densities >100 mJy at 500 μm, but are not visible in existing optical imaging. We fit light profiles to each component of the lensing systems in Spitzer IRAC 3.6 and 4.5 μm data and successfully disentangle the foreground lens from the background source in each case, providing important constraints on the spectral energy distributions (SEDs) of the background SMG at rest-frame optical–near-infrared wavelengths. The SED fits show that these two SMGs have high dust obscuration with A_V ~ 4–5 and star formation rates of ~100M_⊙ yr^(−1). They have low gas fractions and low dynamical masses compared with 850 μm selected galaxies

Charting self-esteem during marital dissolution.

ObjectiveThe purpose of this study was to chart changes in self-esteem before and after marital dissolution to identify the factors that shape individuals' self-esteem during this life transition.MethodWe analyzed 10 annual waves of self-esteem data from 291 divorcees from a nationally representative panel study of the Netherlands (N ~ 13,000). We charted the course of self-esteem before and after marital dissolution and tested a broad set of moderator variables that may shape individuals' self-esteem trajectories.ResultsThe average divorcee experienced significant decrease in self-esteem preceding marital dissolution and remained stable afterward. There were substantial individual differences in self-esteem trajectories, both before and after marital separation. Divorcees who experienced financial hardship, were affiliated with a church or religion, or scored low in Conscientiousness showed the most pronounced decrease in self-esteem during the years approaching marital dissolution.ConclusionThis study highlights the importance of assessing people multiple times before and after marital dissolution to dissect how people approach and respond to this life event. Results are consistent with perspectives that view divorce as an opportunity to abate the strains of an unhappy marriage

Working in partnership with vulnerable families: The experience of child and family health practitioners

Family circumstances in infancy are persistent and powerful determinants of children's physical and mental health, influencing inequalities that trace from childhood through to adulthood. While the social factors that perpetuate patterns of inequality are more complex than can be addressed through single interventions, child and family health (CFH) services represent crucial sites where trajectories of inequality can be disrupted. In particular, approaches that foster opportunities for practitionerparent engagement that challenge traditional hierarchical health care practice, such as the Family Partnership Model (FPM), are recommended as ways of addressing disadvantage. Little is known about how practitioners implement models of working in partnership with families and, consequently, there is a gap in understanding how best to develop and sustain these new CFH practices. This paper reports a research project that investigated the experiences of 25 health professionals working within a FPM framework with vulnerable families. Through discussion of four key themes redefining expertise, changing practices, establishing new relationships with parents and the complexities of partnership practice the paper offers first-hand accounts of reframing practices that recognise the needs, skills and expertise of parents and thus contribute to empowerment of families. © 2011 La Trobe University

The impact of genetic counselling on risk perception in women with a family history of breast cancer.

Women with a family history of breast cancer generally self-refer because they have a feeling that their risk is high. However, they have, in general, only a hazy notion of the population risk of breast cancer and their own risk in relation to this. It is probable that they are helped by genetic counselling and, if at substantial risk, by annual mammography. However, the psychological impact of assigning true risk and the value of mammography need to be evaluated. We have assessed risk perception by questionnaire in 517 new referrals to a family history clinic and 200 women returning to the clinic at least 1 year after counselling. Correct assignment of population lifetime risk of breast cancer was 16% in the uninformed precounsel group and 33% in the post-counsel group, likewise personal risk was correct in 11% and 41% respectively. Post-counsel women were significantly more likely to retain information if they were sent a post-clinic letter or if they assessed their personal risk as too high initially
