When Mom or Dad Has a Mental Illness: General Information and Memories of a Girl Whose Father Has Bi-polar Disorder

This original material answers common questions that children in middle childhood (8-12 years) may have about parental mental illness. When Mom or Dad has a mental illness: General information and memories of a girl whose father has Bi-polar Disorder defines mental illness, addresses symptoms, causes and treatments, provides definitions of related terms, and shares personal stories about having a parent with mental illness. A review of current literature shows the lack of similar work, and the developmental theories of Piaget, Kohlberg, Gilligan, Erikson, and Vygotsky confirm the importance and validity of the project. The motivation behind this work is to provide children with the information about parental mental illness that the author wishes she had as a child

The Host Galaxy of GRB 060505: Host ISM Properties

We investigate the ISM environment of GRB 060505. Using optical emission-line diagnostic ratios, we compare the ISM properties of the GRB 060505 host region with the hosts of unambiguous long- and short-duration GRBs. We show that the metallicity, ionization state, and star formation rate of the GRB 060505 environment are more consistent with short-duration GRBs than with long-duration GRBs. We compare the metallicity and star formation rates of the GRB 060505 region with four other star-forming regions within the GRB 060505 host galaxy. We find no significant change in metallicity or star formation rate between the GRB 060505 region and the other four host regions. Our results are consistent with a compact-object-merger progenitor for GRB 060505.Comment: 7 pages, two figures; accepted for publication in ApJ

Third chromosome candidate genes for conspecific sperm precedence between D. simulans and D. mauritiana

<p>Abstract</p> <p>Background</p> <p>Male - female incompatibilities can be critical in keeping species as separate and discrete units. Premating incompatibilities and postzygotic hybrid sterility/inviability have been widely studied as isolating barriers between species. In recent years, a number of studies have brought attention to postmating prezygotic barriers arising from male - male competition and male - female interactions. Yet little is known about the genetic basis of postmating prezygotic isolation barriers between species.</p> <p>Results</p> <p>Using <it>D. simulans </it>lines with mapped introgressions of <it>D. mauritiana </it>into their third chromosome, we find at least two <it>D. mauritiana </it>introgressions causing male breakdown in competitive paternity success. Eighty one genes within the mapped introgressed regions were identified as broad-sense candidates on the basis of male reproductive tract expression and male-related function. The list of candidates was narrowed down to five genes based on differences in male reproductive tract expression between <it>D. simulans </it>and <it>D. mauritiana</it>. Another ten genes were confirmed as candidates using evidence of adaptive gene coding sequence diversification in the <it>D. simulans </it>and/or <it>D. mauritiana </it>lineage. Our results show a complex genetic basis for conspecific sperm precedence, with evidence of gene interactions between at least two third chromosome loci. Pleiotropy is also evident from correlation between conspecific sperm precedence and female induced fecundity and the identification of candidate genes that might exert an effect through genetic conflict and immunity.</p> <p>Conclusions</p> <p>We identified at least two loci responsible for conspecific sperm precedence. A third of candidate genes within these two loci are located in the 89B cytogenetic position, highlighting a possible major role for this chromosome position during the evolution of species specific adaptations to postmating prezygotic reproductive challenges.</p

Out-of-pocket healthcare expenditure and chronic disease – do Australians forgo care because of the cost?

Although we do know that out-of-pocket healthcare expenditure is relatively high in Australia, little is known about what health conditions are associated with the highest out-of-pocket expenditure, and whether the cost of healthcare acts as a barrier to care for people with different chronic conditions. Cross-sectional analysis using linear and logistic regression models applied to the Commonwealth Fund international health policy survey of adults aged 18 years and over was conducted in 2013. Adults with asthma, emphysema and chronic obstructive pulmonary disease (COPD) had 109% higher household out-of-pocket healthcare expenditure than did those with no health condition (95% CI: 50-193%); and adults with depression, anxiety and other mental health conditions had 95% higher household out-of-pocket expenditure (95% CI: 33-187%). People with a chronic condition were also more likely to forego care because of cost. People with depression, anxiety and other mental health conditions had 7.65 times higher odds of skipping healthcare (95% CI: 4.13-14.20), and people with asthma, emphysema and chronic obstructive pulmonary disease had 6.16 times higher odds of skipping healthcare (95% CI: 3.30-11.50) than did people with no health condition. People with chronic health conditions in Canada, the United Kingdom, Germany, France, Norway, Sweden and Switzerland were all significantly less likely to skip healthcare because of cost than were people with a condition in Australia. The out-of-pocket cost of healthcare in Australia acts as a barrier to accessing treatment for people with chronic health conditions, with people with mental health conditions being likely to skip care. Attention should be given to the accessibility and affordability of mental health services in Australia

No Correlation Between Host Galaxy Metallicity and Gamma-Ray Energy Release for Long-Duration Gamma-Ray Bursts

We compare the redshifts, host galaxy metallicities, and isotropic (E_gamma,iso) and beaming-corrected (E_gamma) gamma-ray energy release of 16 long-duration gamma-ray bursts (LGRBs) at z < 1. From this comparison, we find no statistically significant correlation between host metallicity and redshift, E_gamma,iso, or E_gamma. These results are at odds with previous theoretical and observational predictions of an inverse correlation between gamma-ray energy release and host metallicity, as well as the standard predictions of metallicity-driven wind effects in stellar evolutionary models. We consider the implications that these results have for LGRB progenitor scenarios, and discuss our current understanding of the role that metallicity plays in the production of LGRBs.Comment: 13 pages, 1 figure; accepted to Astrophysical Journa

The Host Galaxies of Gamma-Ray Bursts I: ISM Properties of Ten Nearby Long-Duration GRB Hosts

We present the first observations from a large-scale survey of nearby (z < 1) long-duration gamma-ray burst (LGRB) host galaxies, which consist of eight rest-frame optical spectra obtained at Keck and Magellan. Along with two host galaxy observations from the literature, we use optical emission line diagnostics to determine metallicities, ionization parameters, young stellar population ages, and star formation rates. We compare the LGRB host environments to a variety of local and intermediate-redshift galaxy populations, as well as the newest grid of stellar population synthesis and photoionization models generated with the Starburst99/Mappings codes. With these comparisons we investigate whether the GRB host galaxies are consistent with the properties of the general galaxy population, and therefore whether they may be used as reliable tracers of star formation. We find that LGRB host galaxies generally have low-metallicity ISM environments out to z ~ 1. The ISM properties of our GRB hosts, including metallicity, ionization parameter, and young stellar population age, are significantly different from the general galaxy population, host galaxies of nearby broad-lined Type Ic supernovae, and nearby metal-poor galaxies.Comment: 29 pages, 19 figures, 5 tables, accepted for publication in A

Local news and audiences’ wellbeing:the roles of motivation, satisfaction, and trust

Local news plays an important role in generating a sense of community attachment. However, the relationship between local news and wellbeing is less explored. Based on a national survey of 6,367 Australians, this study found that trust in and satisfaction with local news were linked with higher personal and community wellbeing. News-related factors (motivation, satisfaction, trust) were more strongly related to community wellbeing than to personal wellbeing. Accessing local news for community-related reasons was the strongest predictor of wellbeing. Guided by uses and gratifications theory, this study provides new insights into the role of local news in peoples’ lives, and emphasises the need to protect local news from further decline.</p

The Host Galaxies of Gamma-Ray Bursts Ii: A Mass-Metallicity Relation for Long-Duration Gamma-Ray Burst Host Galaxies

We present a statistically robust mass-metallicity relation for long-duration gamma-ray burst (LGRB) host galaxies at z < 1. By comparing the LGRB host mass-metallicity relation to samples representative of the general star-forming galaxy population, we conclude that LGRBs occur in host galaxies with lower metallicities than the general population, and that this trend extends to z ∼ 1, with an average offset of −0.42 ± 0.18 from the M-Z relation for star-forming galaxies. Our sample in this work includes new spectroscopic data for 6 LGRB host galaxies obtained at the Keck and Magellan telecopes, as well as 2 new host galaxies from the literature. Combined with data from our previous work, this yields a total sample 6 LGRB host galaxies at z < 0.3 and 10 host galaxies at 0.3 < z < 1. We have determined a number of interstellar medium properties for our host galaxies using optical emission-line diagnostics, including metallicity, ionization parameter, young stellar population age, and star formation rate. Across our full sample of 16 LGRB hosts we find an average metallicity of log(O/H) + 12 = 8.4 ± 0.3. Notably, we also measure a comparatively high metallicity of log(O/H) + 12 = 8.83 ± 0.1 for the z = 0.296 host galaxy of GRB 050826. We also determine stellar masses (M⋆) for our LGRB host galaxy sample, finding a mean stellar mass of log(M⋆/M⊙) = 9.25+0.19−0.23.Astronom
