Deconstructing the LGBT-Victimization Association: The Case of Sexual Assault and Alcohol-Related Problems

Research on lesbian, gay, bisexual and/or transgender (LGBT) students has been gaining traction in the fields of criminology, victimology, and education, but available data lag behind the demand for studies on this underserved population. While LGBT students are often perceived to face greater risk of victimization and subsequent health problems than their counterparts, little research has investigated the mechanisms behind problematic outcomes for LGBT students. This research uses data from a Southeastern University to examine sexual assault among LGBT students and their experiences with alcohol-related problems. The results show that LGBT youth are at an increased risk for sexual victimization but that LGBT status does not have a direct effect on alcohol-related problems

Does Parental Control Moderate the Effect of Low Self-Control on Adolescent Offline and Online Delinquency?

The article elaborates on central interpretations of the general theory of crime regarding parental control, self-control, and delinquency by analyzing the effect of parental control on the association between low self-control and adolescents' offline and online delinquency. Analyses employ mediation and moderation models via structural equation modeling with a nationally representative sample of Finnish adolescents (N = 6,061). Results indicate parental control had direct and indirect associations (via self-control) with offline delinquency. Whereas, parental control had only an indirect association with delinquency online. The direct association between self-control (internal control) and offline and online delinquency was moderated by parental social control (external control). General theory of crime provides a useful perspective for exploring the effect of parental control on adolescents' delinquency. Findings bring new evidence on the dynamics between low self-control and parental control. Future studies should continue investigating the interplay between internal and external controls.Peer reviewe

Examining Sanction Type and Drug Offender Recidivism : A Register-Based Study in Finland

Nordic countries incarcerate offenders at much lower rates in comparison with incarceration rates in the United States, and reincarcerate fewer people per capita. Non-custodial alternatives to sanctions, including fines and community service, are used extensively in Finland to reduce negative effects of institutionalization and subsequent disadvantage caused by incarceration. The nature of drug-involved offenders within the Finnish system is reviewed in light of current research about the effectiveness of incarceration and deterrence-based approaches for drug offenders. Employing a 2014 sample from register data (consisting of official government records) of drug offenders in Finland with a 3-year recidivism period, this study utilizes a genetic matching procedure to compare offenders who received fines, conditional sentences (probation), or incarceration. While recognizing that numerous confounding variables affect incarceration, we compare a matched sample of drug offenders and the sanctions they have received from the Finland judicial system to determine whether offenders who initially receive a fine or a conditional sentence reenter the correctional system at different rates than those who are incarcerated. After matching, results found no significant differences between offenders receiving incarceration sentences or those who received noncustodial sentences (fine, or conditional sentence) for general and drug-related recidivism. These results are presented within the context of the Finnish corrections system in order to inform the criminal justice community about culture, incarceration, and process differences that could positively affect working with drug offenders in other localities.Nordic countries incarcerate offenders at much lower rates in comparison with incarceration rates in the United States, and reincarcerate fewer people per capita.

The Association Between Social Media Use and Hazardous Alcohol Use Among Youths : A Four-Country Study

Aims: To examine the continuing role of daily popular social media use in youth hazardous alcohol consumption in four countries across continents. Methods: A web-based survey was given to youths aged 15-25 in the USA (n = 1212), South Korea (n = 1192), Finland (n = 1200) and Spain (n = 1212). Hazardous alcohol use (alcohol use disorders identification test-C) was the dependent variable. Main independent variables measured daily use of different social media services. Controls included compulsive Internet use, offline belonging, psychological distress, impulsivity, risk-taking, age and gender. Linear regression models and mediation analyses with bootstrapping were done for each country. Results: Daily use of Facebook and Instagram was associated with higher hazardous alcohol use among youths in Finland, South Korea and Spain. Daily instant messaging was related to higher hazardous alcohol use among South Korean and Finnish youths. Daily YouTube use was associated with higher hazardous alcohol use among youths in South Korea, but lower hazardous alcohol use among youths in the USA and Finland. Daily Twitter use was related to lower hazardous drinking among youths in Finland but higher hazardous drinking among youths in Spain. The mediation analyses revealed that uploading pictures to social media is a possible facilitator of social media-related hazardous alcohol use among youths in the USA and Spain. Conclusion: Certain social media platforms might inspire and/or attract hazardously drinking youths, contributing to the growing opportunities for social media interventions.Peer reviewe

The Star Formation History of LGS 3

We have determined the distance and star formation history of the Local Group dwarf galaxy LGS 3 from deep Hubble Space Telescope WFPC2 observations. LGS 3 is intriguing because ground-based observations showed that, while its stellar population is dominated by old, metal-poor stars, there is a handful of young, blue stars. Also, the presence of HI gas makes this a possible ``transition object'' between dwarf spheroidal and dwarf irregular galaxies. The HST data are deep enough to detect the horizontal branch and young main sequence for the first time. A new distance of D=620+/-20 kpc has been measured from the positions of the TRGB, the red clump, and the horizontal branch. The mean metallicity of the stars older than 8 Gyr is Fe/H = -1.5 +/- 0.3. The most recent generation of stars has Fe/H ~ -1. For the first few Gyr the global star formation rate was several times higher than the historical average and has been fairly constant since then. However, we do see significant changes in stellar populations and star formation history with radial position in the galaxy. Most of the young stars are found in the central 63 pc (21''), where the star formation rate has been relatively constant, while the outer parts have had a declining star formation rate.Comment: To appear in The Astrophysical Journal, 26 pages, 14 figures, uses AASTe

A framework for improving early detection of breast cancer in sub-Saharan Africa: A qualitative study of help-seeking behaviors among Malawian women

Many women in Africa are diagnosed with advanced breast cancer. We explored Malawian breast cancer patients’ perspectives about their diagnosis and ability to access care to identify help-seeking behaviors and to describe factors influencing delay

Chemical Abundances of Seven Irregular and Three Tidal Dwarf Galaxies in the M81 Group

We have derived nebular abundances for 10 dwarf galaxies belonging to the M81 Group, including several galaxies which do not have abundances previously reported in the literature. For each galaxy, multiple H \ii regions were observed with GMOS-N at the Gemini Observatory in order to determine abundances of several elements (oxygen, nitrogen, sulfur, neon, and argon). For seven galaxies, at least one H \ii region had a detection of the temperature sensitive [OIII] $\lambda$4363 line, allowing a "direct" determination of the oxygen abundance. No abundance gradients were detected in the targeted galaxies and the observed oxygen abundances are typically in agreement with the well known metallicity-luminosity relation. However, three candidate "tidal dwarf" galaxies lie well off this relation, UGC 5336, Garland, and KDG 61. The nature of these systems suggests that UGC 5336 and Garland are indeed recently formed systems, whereas KDG 61 is most likely a dwarf spheroidal galaxy which lies along the same line of sight as the M81 tidal debris field. We propose that these H \ii regions formed from previously enriched gas which was stripped from nearby massive galaxies (e.g., NGC 3077 and M81) during a recent tidal interaction.Comment: 37 pages, 10 figures, accepted for publication in ApJ.

Chandra Observation of the Globular Cluster NGC 6440 and the Nature of Cluster X-ray Luminosity Functions

As part of our campaign to determine the nature of the various source populations of the low-luminosity globular cluster X-ray sources, we have obtained a Chandra X-ray Observatory ACIS-S3 image of the globular cluster NGC 6440. We detect 24 sources to a limiting luminosity of ~2 times 10^31 erg/s (0.5-2.5keV) inside the cluster's half-mass radius, all of which lie within ~2 core radii of the cluster center. We also find excess emission in and around the core which could be due to unresolved point sources. Based upon X-ray luminosities and colors, we conclude that there are 4-5 likely quiescent low-mass X-ray binaries and that most of the other sources are cataclysmic variables. We compare these results to Chandra results from other globular clusters and find the X-ray luminosity functions differ among the clusters.Comment: 9 pages, 4 figures, accepted by ApJ, minor changes, added table of clusters' physical parameter

Star Formation in Dwarf Galaxies of the Nearby Centaurus A Group

We present Halpha narrow-band imaging of 17 dwarf irregular galaxies (dIs) in the nearby Centaurus A Group. Although all large galaxies of the group have a current or recent enhanced star formation episode, the dIs have normal star formation rates and do not contain a larger fraction of dwarf starbursts than other nearby groups. Relative distances between dIs and larger galaxies of the group can be computed in 3D since most of them have now fairly accurately known distances. We find that the dI star formation rates do not depend on local environment, and in particular they do not show any correlation with the distance of the dI to the nearest large galaxy of the group. There is a clear morphology-density relation in the Centaurus A Group, similarly to the Sculptor and Local Groups, in the sense that dEs/dSphs tend to be at small distances from the more massive galaxies of the group, while dIs are on average at larger distances. We find four transition dwarfs in the Group, dwarfs that show characteristics of both dE/dSphs and dIs, and which contain cold gas but no current star formation. Interestingly the transition dwarfs have an average distance to the more massive galaxies which is intermediate between those of the dEs/dSphs and dIs, and which is quite large: 0.54 +- 0.31 Mpc. This large distance poses some difficulty for the most popular scenarios proposed for transforming a dI into a dE/dSph (ram-pressure with tidal stripping or galaxy harassment). If the observed transition dwarfs are indeed missing links between dIs and dE/dSphs, their relative isolation makes it less likely to have been produced by these mechanisms. We propose that an inhomogeneous IGM containing higher density clumps would be able to ram-pressure stripped the dIs at such large distances.Comment: 57 pages, 10 fi5gure

Salmonella Enteritidis bacteriophage candidates for phage therapy of poultry

Aims: Salmonella is a worldwide foodborne pathogen causing acute enteric infections in humans. In the recent years, the use of bacteriophages has been suggested as a possible tool to combat this zoonotic pathogen in poultry farms. This work aims to isolate and perform comparative studies of a group of phages active against a collection of specific Salmonella Enteritidis strains from Portugal and England. Also, suitable phage candidates for therapy of poultry will be selected. Methods and Results: The Salm. Enteritidis strains studied were shown to have a significantly high occurrence of defective (cryptic) prophages; however, no live phages were found in the strains. Bacteriophages isolated from different environments lysed all except one of the tested Salm. Enteritidis strains. The bacteriophages studied were divided into different groups according to their genetic homology, RFLP profiles and phenotypic features, and most of them showed no DNA homology with the bacterial hosts. The bacteriophage lytic efficacy proved to be highly dependent on the propagation host strain. Conclusions: Despite the evidences shown in this work that the Salm. Enteritidis strains used did not produce viable phages, we have confirmed that some phages, when grown on particular hosts, behaved as complexes of phages. This is most likely because of the presence of inactive phage-related genomes (or their parts) in the bacterial strains which are capable of being reactivated or which can recombine with lytic phages. Furthermore, changes of the bacterial hosts used for maintenance of phages must be avoided as these can drastically modify the parameters of the phage preparations, including host range and lytic activity. Significance and Impact of the Study: This work shows that the optimal host and growth conditions must be carefully studied and selected for the production of each bacteriophage candidate for animal therapy.The authors kindly acknowledge the Instituto Nacional Ricardo Jorge (INRJ) (Portugal) and also Tom Humphrey from the Division of Farm Animal Science, School of Clinical Veterinary Science of the University of Bristol (UK) for providing the Salm.
