Text 4 Health: Addressing Consumer Health Information Needs via Text Reference Service

This study seeks to provide empirical evidence about how health-related questions are answered in text reference service in order to further the understanding of how to best use texting as a reference service venue to fulfill people’s health information needs. Two hundred health reference transactions from My Info Quest, the first nation-wide collaborative text reference service, were analyzed identify the types of questions, length of transactions, question-answering behavior, and information sources used in the transactions. Findings indicate that texting-based health reference transactions are usually brief, and cover a wide variety of topics. The most popular questions are those seeking general factual information about human body, medical/health conditions, diseases, or medical concepts/jargons. Great variance is discovered among the question-answering behavior, with only a little more than half of the answers containing citation to information sources. The study will inform the practice of health reference service via texting, and help libraries make evidence-based decisions on establishing service policies and procedures, providing training for librarians, and ultimately implementing the service successfully

Preparing public librarians for consumer health information service: A nation-wide study

A nationwide survey study was conducted to gain understanding as to how to prepare public librarians for consumer health information service. Findings indicate that the popular health information needs encountered by public librarians cover a wide variety of topics, including the human body, a medical/health condition, a disease, a medical concept, and fitness/diet/nutrition. The top two challenges faced by public librarians when providing consumer health information service are difficulty in interpreting patrons\u27 questions and lack of knowledge about available and trusted/appropriate medical/health information sources. Public librarians wish to receive training on a number of topics that could help address the challenges they face, and the most favorable training format for them, among all the options provided in the survey, is the self-paced online tutorial. This study constitutes the basis for establishing training requirements and developing training programs to meet the needs of public librarians. Their mastery of the necessary skills, knowledge and competencies via training will lead to effective and efficient delivery of consumer health information service in public libraries, and ultimately generate optimal patron experiences

Oxo and Oxofree Rhenium(V) Complexes with N,O-donor Schiff Bases

The reaction between cis-[ReVO2I(PPh3)2] and H3duo (N-(2-hydroxybenzylidene)-5-amino-1,3-dimethyl uracil) led to the formation of the oxofree, imido compound, trans-[ReV(ddd)(Hduo)(PPh3)2]I (1) (H2ddd=5,6-diamino-1,3-dimethyluracil). An oxo complex, cis-[ReV(bcp)OCl2(PPh3)](2) [Hbcp = N-(2-hydroxybenzylidene)-benzothiazole] was isolated from the reaction of trans-[ReOVCl3(PPh3)2] with Hbcp. The crystal structures of the compounds were determined by single crystal X-ray diffraction.Keywords: Rhenium(V), imido, oxo, crystal structure, spectral characterizatio

Patients’ reports about medical doctors’ inquiries on their mental health: Do generational status, ethnicity and mental health/substance use disorders matter?

Immigrants are less likely than others to use mental health (MH) services. Physicians\u27 limited time often precludes inquiry about MH. This study investigated the influence of generational status, ethnicity, and mental/substance use disorders on physicians\u27 inquiries about Asian American (AA) MH. Data from the National Latino and Asian American Study were analyzed (n=1,853). The outcome was past year physician\u27s inquiry regarding MH. Results revealed that AA with U.S.-born parents had significantly greater odds compared to AA born outside the U.S. to report that their doctors inquired about their MH (OR=218, 95% CI: 1.28, 3.73). Past year mental/substance use disorder increased the odds of AA reporting that their doctors inquired about their MH (OR=8.41; 95% CI: 3.28, 21.66). This increase differed by ethnicity, with Chinese less affected than Vietnamese (OR=0.17; 95% CI: 0.05, 0.59). The reasons for these associations warrant further exploration

Prevalence, patterns, and correlates of co-occurring substance use and mental disorders in the U.S.: Variations by race/ethnicity

This study examines racial/ethnic differences in the prevalence, patterns, and correlates of co-occurring substance use and mental disorders (COD) among Whites, Blacks, Latinos, and Asians using data from the Collaborative Psychiatric Epidemiology Studies

‘Bring back Hitler’s gas chambers’: asylum seeking, Nazis and facebook – a discursive analysis

In this article, we explore how talk about Nazis is used in Internet discussions regarding asylum seeking, and the issue of whether or not opposition to asylum seeking is racist. Discursive analysis was conducted on discussions about asylum seeking from the social networking website Facebook, where references to Nazis were made. Three strategies were identified: (1) people supporting asylum seeking accuse asylum opponents of being racist by referring to Nazis; (2) opponents of asylum seeking deal with such accusations by arguing that the debate is being suppressed because of references to Nazis; (3) in the final, and most striking, strategy, opponents of asylum draw upon ideas associated with the Nazis and Hitler to bring about their anti-asylum position. These findings are discussed in relation to how the link between Nazis and racism is emerging in the asylum debat

How large should whales be?

The evolution and distribution of species body sizes for terrestrial mammals is well-explained by a macroevolutionary tradeoff between short-term selective advantages and long-term extinction risks from increased species body size, unfolding above the 2g minimum size induced by thermoregulation in air. Here, we consider whether this same tradeoff, formalized as a constrained convection-reaction-diffusion system, can also explain the sizes of fully aquatic mammals, which have not previously been considered. By replacing the terrestrial minimum with a pelagic one, at roughly 7000g, the terrestrial mammal tradeoff model accurately predicts, with no tunable parameters, the observed body masses of all extant cetacean species, including the 175,000,000g Blue Whale. This strong agreement between theory and data suggests that a universal macroevolutionary tradeoff governs body size evolution for all mammals, regardless of their habitat. The dramatic sizes of cetaceans can thus be attributed mainly to the increased convective heat loss is water, which shifts the species size distribution upward and pushes its right tail into ranges inaccessible to terrestrial mammals. Under this macroevolutionary tradeoff, the largest expected species occurs where the rate at which smaller-bodied species move up into large-bodied niches approximately equals the rate at which extinction removes them.Comment: 7 pages, 3 figures, 2 data table

Intracellular uptake of macromolecules by brain lymphatic endothelial cells during zebrafish embryonic development

The lymphatic system controls fluid homeostasis and the clearance of macromolecules from interstitial compartments. In mammals brain lymphatics were only recently discovered, with significant implications for physiology and disease. We examined zebrafish for the presence of brain lymphatics and found loosely connected endothelial cells with lymphatic molecular signature covering parts of the brain without forming endothelial tubular structures. These brain lymphatic endothelial cells (BLECs) derive from venous endothelium, are distinct from macrophages, and are sensitive to loss of Vegfc. BLECs endocytose macromolecules in a selective manner, which can be blocked by injection of mannose receptor ligands. This first report on brain lymphatic endothelial cells in a vertebrate embryo identifies cells with unique features, including the uptake of macromolecules at a single cell level. Future studies will address whether this represents an uptake mechanism that is conserved in mammals and how these cells affect functions of the embryonic and adult brain

Beyond the Refugee Crisis how the UK news media represent asylum seekers across national boundaries

Migration is one of the most pressing, divisive issues in global politics today, and media play a crucial role in how communities understand and respond. This study examines how UK newspapers (n = 974) and popular news websites (n = 1044) reported on asylum seekers throughout 2017. It contributes to previous literature in two important ways. First, by examining the ‘new normal’ of daily news coverage in the wake of the 2015 ‘refugee crisis’ in Europe. Second, by looking at how asylum seekers from different regions are represented. The content analysis finds significant variations in how asylum seekers are reported, including terminology use and topics they are associated with. The paper also identifies important commonalities in how all asylum seekers are represented - most notably, the dominance of political elites as sources across all media content. It argues that Entman’s ‘cascade network model’ can help to explain this, with elites in one country able to influence transnational reports
