Depression And Perceived Stress as Mediators Between Racial Microaggressions and Somatic Symptoms in College Students of Color
The current study examined the ability of mental health indicators, namely depression and perceived stress, to mediate the relationship between racial microaggressions and health among a racially/ethnically diverse sample of 467 college students of color. Consistent with what was hypothesized, the main findings revealed that depression and perceived stress mediated the relationships between types of racial microaggressions, specifically low-achieving, invisibility, and criminality, and somatic symptoms. The study results suggest that there may be multiple pathways by which specific racial microaggressions might be associated with psychological and somatic health indicators
Disability in Chronic Fatigue Syndrome and Idiopathic Chronic Fatigue
The current investigation classified 31 people with chronic fatigue syndrome (CFS) and 44 people with idiopathic chronic fatigue (ICF) into mild, moderate, and severe/very severe categories of self reported functional impairment. Differences in sociodemographic characteristics, symptom frequency, symptom severity, and functional impairment were examined between individuals with CFS and ICF, and were examined among the three categories of functional impairment. Results indicated that there were no differences between the CFS and ICF groups in their functional impairment classification. People who were classified into the more disabled categories reported more severe symptoms, and were more likely to have scores indicating higher disability on other measures of functional status. Implications of these findings are discussed
Possible changes of state and relevant timescales for a neutron star in LS I +61{\deg}303
The properties of the short, energetic bursts recently observed from the
gamma-ray binary LS I +61{\deg}303, are typical of those showed by high
magnetic field neutron stars, and thus provide a strong indication in favor of
a neutron star being the compact object in the system. Here, we discuss the
transitions among the states accessible to a neutron star in a system like LS I
+61{\deg}303, such as the ejector, propeller and accretor phases, depending on
the NS spin period, magnetic field and rate of mass captured. We show how the
observed bolometric luminosity (>= few x 1E35 erg/s), and its broad-band
spectral distribution, indicate that the compact object is most probably close
to the transition between working as an ejector all along its orbit, and being
powered by the propeller effect when it is close to the orbit periastron, in a
so-called flip-flop state. By assessing the torques acting onto the compact
object in the various states, we follow the spin evolution of the system,
evaluating the time spent by the system in each of them. Even taking into
account the constraint set by the observed gamma-ray luminosity, we found that
the total age of the system is compatible with being ~5-10 kyr, comparable to
the typical spin-down ages of high-field neutron stars. The results obtained
are discussed in the context of the various evolutionary stages expected for a
neutron star with a high mass companion.Comment: 12 pages, 6 figures. Accepted for publication in Ap
Doctoral‐Level Counseling Students’ Experiences of Social Class Microaggressions
The authors recruited 11 doctoral‐level counseling students to participate in a study exploring the lived experiences of people who have encountered social class microaggressions (SCMs). Findings (consisting of 6 themes) suggest that SCMs are a distinct phenomenon arising from interpersonal and environmental exchanges that damage recipients. The authors present implications for counselor education and future research trajectories
The Fragility of Gender Equality Policies in Spain
Within the last decade, Spain has become a model in legislative policies for gender equality at the international level. However, the economic crisis has led to a growth in inequality, which has revealed the weaknesses of the adopted instruments. Despite the large amount of legislation in this area, the social reality has not changed at all, even experiencing a setback over the past few years. This situation was exposed in our country by a report issued in 2015 by the UN Committee on the Elimination of Discrimination against Women (CEDAW). This report showed the negative effects of the economic crisis and austerity policies on women, even in a context necessitating increased efforts towards women’s rights. Therefore, it is imperative that the concept of gender mainstreaming and the adoption of instruments of “hard law” be revisited. The goal should be to achieve gender justice based on three elements—distribution, identity, and representation—and a real parity democracy
Observation of EGRET Gamma-Ray Sources by an Extensive Air Shower Experiment
Ultra-high-energy (E100 Tev) Extensive Air Showers (EASs) have been
monitored for a period of five years (1997 - 2003), using a small array of
scintillator detectors in Tehran, Iran. The data have been analyzed to take in
to account of the dependence of source counts with respect to the zenith angle.
During a calendar year different sources come in the field of view of the
detector at varying zenith angles. Because of varying thickness of the
overlaying atmosphere, the shower count rate is extremely dependent on zenith
angle which have been carefully analyzed over time. High energy gamma-ray
sources from EGRET third catalogue where observed and the data were analyzed
using an excess method. A number of upper limits for a number of EGRET sources
were obtained, including 6 AGNs or probably AGNs and 4 unidentified sources.Comment: 14 pages, 8 figures, Astronomy and Astrophysics, accepte

SDSS-III Baryon Oscillation Spectroscopic Survey data release 12 : galaxy target selection and large-scale structure catalogues
The Baryon Oscillation Spectroscopic Survey (BOSS), part of the Sloan Digital Sky Survey (SDSS) III project, has provided the largest survey of galaxy redshifts available to date, in terms of both the number of galaxy redshifts measured by a single survey, and the effective cosmological volume covered. Key to analysing the clustering of these data to provide cosmological measurements is understanding the detailed properties of this sample. Potential issues include variations in the target catalogue caused by changes either in the targeting algorithm or properties of the data used, the pattern of spectroscopic observations, the spatial distribution of targets for which redshifts were not obtained, and variations in the target sky density due to observational systematics. We document here the target selection algorithms used to create the galaxy samples that comprise BOSS. We also present the algorithms used to create large-scale structure catalogues for the final Data Release (DR12) samples and the associated random catalogues that quantify the survey mask. The algorithms are an evolution of those used by the BOSS team to construct catalogues from earlier data, and have been designed to accurately quantify the galaxy sample. The code used, designated mksample, is released with this paper.Publisher PDFPeer reviewe
GLAST: Understanding the High Energy Gamma-Ray Sky
We discuss the ability of the GLAST Large Area Telescope (LAT) to identify,
resolve, and study the high energy gamma-ray sky. Compared to previous
instruments the telescope will have greatly improved sensitivity and ability to
localize gamma-ray point sources. The ability to resolve the location and
identity of EGRET unidentified sources is described. We summarize the current
knowledge of the high energy gamma-ray sky and discuss the astrophysics of
known and some prospective classes of gamma-ray emitters. In addition, we also
describe the potential of GLAST to resolve old puzzles and to discover new
classes of sources.Comment: To appear in Cosmic Gamma Ray Sources, Kluwer ASSL Series, Edited by
