Coming Out Late:The Impact on Individuals\u27 Social Networks

Social support is a key factor influencing older adults’ health and well-being. Disclosing one’s lesbian, gay, or bisexual identity at any age has great potential for altering, if not destroying, existing relationships with family, friends, and others. With long-established social roles and personal relationships, the potential risks may be accentuated for those who come out in mid- or later-life. Yet, researchers have paid scant attention to this phenomenon. This exploratory qualitative study examines the impact of coming out “late” on older adults’ social networks. In-depth interviews were conducted with a sample of fourteen older adults who disclosed their non-heterosexual identity at or after age 39. Interviews inquired about participants’ past and present social networks and the coming out process, particularly the influence of coming out “off time.” Findings show coming out is a dynamic, continuous, and non-linear process that simultaneously characterizes and is characterized by social network gains and losses

Impact of childhood experience and adult well-being on eating preferences and behaviours

OBJECTIVES: To examine the relative contribution of childhood experience, measured by childhood violence and childhood happiness, and adult well-being on adult eating preferences and behaviours, independent of proximal factors such as current deprivation. DESIGN: A cross-sectional, stratified, randomised sample survey using retrospective measures of childhood violence and happiness and self-reported measures of current well-being. SETTING: The North West Region of England between September 2012 and March 2013. PARTICIPANTS: Individuals aged 18–95-year-olds from randomly selected households (participation was successful for 90% of eligible households and 78% of the total visited addresses; n=11 243). OUTCOMES: Dichotomised measures for preference of healthy foods or ‘feel good’ foods and low or high daily fruit and vegetable consumption. RESULTS: After correcting for demographics, combined categories for childhood experience and dichotomised measures of adult well-being were found to be significantly related to adult food preferences and eating behaviours. Participants with unhappy and violent childhoods compared to those with happy and non-violent childhoods had adjusted ORs (95% CI, significance) of 2.67 (2.15 to 3.06, p<0.001) of having low daily fruit and vegetable intake (two or less portions) and 1.53 (1.29 to 1.81, p<0.001) of choosing ‘feel good’ foods over foods which were good for their long term health. CONCLUSIONS: Daily intake of fruit and vegetables, linked to non-communicable diseases, and preference for ‘feel good’ foods, linked to obesity, are affected by childhood experience and adult well-being independent of demographic factors. Preventative interventions which support parent–child relationships and improve childhood experience are likely to reduce the development of poor dietary and other health-risk behaviours

Scholarly Database

The Scholarly Database (SDB) aims to serve the needs of researchers and practitioners interested in the analysis, modeling, and visualization of large-scale scholarly datasets. The database currently provides access to 11 major datasets such as Medline, U.S. patents, National Science Foundation and National Institutes of Health funding awards - a total of about 20 million records. The books, journals, proceedings, patents, grants, technical reports, doctoral and master theses can be cross searched. Results can be downloaded as data dumps for further processing. The online interface at https://sdb.School of Library and Information Science.indiana.edu provides full-text search for four databases (MEDLINE, NSF, NIH, USPTO) using Solar. Specifically, it is able to search and filter the contents of these databases using many criteria and search fields, particularly those relevant for scientometric research and science policy practice

Flux transfer events: Scale size and interior structure

We report the first direct investigation of the spatial properties of flux transfer events (FTEs) at the Earth's dayside magnetopause. Simultaneous magnetometer and plasma data from the ISEE 1 and 2 satellites are combined to show that magnetosheath FTEs can have a scale size of order an Earth radius in the magnetopause normal direction. We confirm that the magnetic field within the events appears to be twisted, this twisting corresponding to a core field‐aligned current of magnitude a few × 105 A. We also show evidence for plasma vorticity in FTEs. The transverse flow and field perturbations accompanying the three events studied obey approximately the Walén relation for a propagating Alfvén wave

The three-dimensional geometry and merger history of the massive galaxy cluster MACS J0358.8-2955

We present results of a combined X-ray/optical analysis of the dynamics of the massive cluster MACS J0358.8-2955 (z=0.428) based on observations with the Chandra X-ray Observatory, the Hubble Space Telescope, and the Keck-I telescope on Mauna Kea. MACS J0358.8-2955 is found to be one of the most X-ray luminous clusters known at z>0.3, featuring L_X(<r_500) = 4.24*10^45 erg/s, kT = (9.55 +0.58/-0.37) keV, M^{3D}_{gas}(<r_500) = (9.18+/-1.45)*10^13 M_sun, and M^{3D}_{tot}(<r_500) = (1.12+/-0.18)*10^15 M_sun. The system's high velocity dispersion of (1440 +130/-110) km/s (890 km/s when the correct relativistic equation is used), however, is inflated by infall along the line of sight, as the result of a complex merger of at least three sub-clusters. One collision proceeds close to head-on, while the second features a significant impact parameter. The temperature variations in the intra-cluster gas, two tentative cold fronts, the radial velocities measured for cluster galaxies, and the small offsets between collisional and non-collisional cluster components all suggest that both merger events are observed close to core passage and along axes that are greatly inclined with respect to the plane of the sky. A strong-lensing analysis of the system anchored upon three triple-image systems (two of which have spectroscopic redshifts) yields independent constraints on the mass distribution. For a gas fraction of 8.2%, the resulting strong-lensing mass profile is in good agreement with our X-ray estimates, and the details of the mass distribution are fully consistent with our interpretation of the three-dimensional merger history of this complex system.Comment: 17 pages, 17 figures, and 4 tables.

Structural variability of 4f and 5f thiocyanate complexes and dissociation of uranium(III)–thiocyanate bonds with increased ionicity

A series of complexes [Et4N][Ln(NCS)4(H2O)4] (Ln = Pr, Tb, Dy, Ho, Yb) have been structurally characterized, all showing the same structure, namely a distorted square antiprismatic coordination geometry, and the Ln–O and Ln–N bond lengths following the expected lanthanide contraction. When the counterion is Cs+, a different structural motif is observed and the eight-coordinate complex Cs5[Nd(NCS)8] isolated. The thorium compounds [Me4N]4[Th(NCS)7(NO3)] and [Me4N]4[Th(NCS)6(NO3)2] have been characterized, and high coordination numbers are also observed. Finally, attempts to synthesize a U(III) thiocyanate compound has been unsuccessful; from the reaction mixture, a heterocycle formed by condensation of five MeCN solvent molecules, possibly promoted by U(III), was isolated and structurally characterized. To rationalize the inability to isolate U(III) thiocyanate compounds, thin-layer cyclic voltammetry and IR spectroelectrochemistry have been utilized to explore the cathodic behavior of [Et4N]4[U(NCS)8] and [Et4N][U(NCS)5(bipy)2] along with a related uranyl compound [Et4N]3[UO2(NCS)5]. In all examples, the reduction triggers a rapid dissociation of [NCS]− ions and decomposition. Interestingly, the oxidation chemistry of [Et4N]3[UO2(NCS)5] in the presence of bipy gives the U(IV) compound [Et4N]4[U(NCS)8], an unusual example of a ligand-based oxidation triggering a metal-based reduction. The experimental results have been augmented by a computational investigation, concluding that the U(III)–NCS bond is more ionic than the U(IV)–NCS bond

El análisis de redes en el estudio de la colaboración científica

El análisis de redes sociales es una herramienta que se usa cada vez más para determinar las relaciones entre los diferentes elementos bibliográficos que componen un trabajo científico. Desde tiempo atrás, las asociaciones entre coautores y entre sus instituciones y países de adscripción, se toman como una formar de medir las colaboraciones en ciencia. En nuestra presentación examinamos cómo el análisis de redes sociales se emplea para lograr una interpretación más acertada de estas relaciones tomando como ejemplo las colaboraciones bilaterales entre los países latinoamericanos.Social network analysis is a tool used increasingly by bibliometricians to determine the relationships between the different bibliographical elements present in a scientific paper. The associations between coauthors or between the institutions or countries they represent, have long been used as an manifestation of collaboration in science. In this presentation we look at how social network analysis is employed to assist in the interpretation of these relationships using examples taken from our work on bilateral collaborations between countries in Latin America
