Help-Seeking Attitudes of United Arab Emirates Students

© Division of Counseling Psychology of the American Psychological Association. The psychological help-seeking patterns of college students in the United Arab Emirates (UAE) have only recently begun to be examined. Initial suggestions indicate that the majority of Emirati students treat help seeking from counselors as a last resort, which may be linked to aspects of Emirati culture including feared loss of societal face, stigma associated with seeking help, and discouragement of self-disclosure to individuals outside of the family. The relationship among fear of losing face, stigma, self-disclosure expectations (i.e., risks and benefits), and help-seeking attitudes was examined using structural equation modeling with 407 Emirati college students. Loss of face and stigma were related to self-disclosure expectations, which in turn were related to help-seeking attitudes. Gender differences were also examined with results indicating significant mean differences across all variables, as well as across two paths of the structural model. These findings are discussed within the cultural context of the UAE

Magnetic properties of triethylene glycol coated CoFe2O4 and Mn0.2Co0.8Fe2O4 NP's synthesized by polyol method

AbstractIn this study, we reported on the structural and magnetic properties of TEG-CoFe2O4 and TEG-Mn0.2Co0.8Fe2O4 nanocomposites produced by the glycothermal reaction (polyol). X-ray diffraction (XRD), transmission electron microscopy (TEM) and vibration sample magnetometer (VSM) analysis have been carried out in order to understand the effect of Mn2+ into CoFe2O4 and it was observed that the addition of Mn2+ tends to reduce the crystallite size, increase the ao (cell parameter) and increase the TB. The presence of adsorbed polyol entities on the surface of the CoFe2O4 and Mn0.2Co0.8Fe2O4 NP's was also proven by TG measurements. FT-IR analysis suggested the presence of adsorbed TEG molecules on the surface of CoFe2O4 and Mn0.2Co0.8Fe2O4 NP's

Cross-Cultural Validation of the Perceptions of Stigmatization by Others for Seeking Help (PSOSH) Scale

Social network stigma refers to the perceived negative views about seeking help for mental health problems that are held by those closest to an individual, such as family and friends. This form of stigma predicts help-seeking attitudes and intentions beyond other forms of stigma, and is predominantly measured using the Perceptions of Stigmatization by Others for Seeking Help scale (PSOSH; Vogel, Wade, & Ascheman, 2009). However, the PSOSH was normed using samples from the United States and, until the cross-cultural validity of this measure is established, it cannot reliably be used within other countries (Miller & Sheu, 2008). As such, the current study (N = 3,440) examined the cross-cultural measurement invariance of the PSOSH using the sequential constraint imposition approach across 11 countries/regions: Australia, Brazil, Canada, Hong Kong, Portugal, Romania, Taiwan, Turkey, the United Arab Emirates (UAE), the United Kingdom (U.K.), and the United States (U.S.). Overall, findings indicate that the PSOSH measures a meaningful construct (i.e., configural and metric invariance) across the 11 countries/regions and that future cross-cultural research could use the PSOSH to examine relationships between social network stigma and other variables. Scalar invariance results also supported the examination of mean differences in Australia, Brazil, Canada, Portugal, Turkey, the U.K., and the U.S., but not in Hong Kong, Romania, Taiwan, and UAE. Implications for future cross-cultural research are discussed

Stigma of Seeking Psychological Services: Examining College Students Across Ten Countries/Regions

© Division of Counseling Psychology of the American Psychological Association. Stigma is an important barrier to seeking psychological services worldwide. Two types of stigma exist: public stigma and self-stigma. Scholars have argued that public stigma leads to self-stigma, and then self-stigma is the primary predictor of attitudes toward seeking psychological services. However, this assertion is largely limited to U.S. samples. The goal of this research was to provide a first step in understanding the relationship between public stigma, self-stigma, and attitudes toward seeking psychological services in international contexts (N = 3,276; Australia, Brazil, Canada, Hong Kong, Portugal, Romania, Taiwan, Turkey, United Arab Emirates, and United States). Using structural equation modeling, we found that self-stigma mediated the relationship between public stigma and attitudes toward seeking services among college students in each country and region. However, differences in path strengths emphasize the need to pay attention to the role of public and self-stigma on attitudes toward seeking psychological services throughout the world

Block Shear Capacity of Bolted Connections in Cold-Reduced Steel Sheets

This paper examines the mechanisms for block shear failures of bolted connections in steel plates postulated in the design equations specified in the North American, European and Australian steel structures codes. It explains that there is only one feasible mechanism for the limit state of conventional block shear failure, that which involves tensile rupture and shear yielding, irrespective of the steel material ductility. It describes the fundamental shortcomings of various code equations for determining the block shear capacity of a bolted connection. Based on the tensile rupture and shear yielding mechanism, an in-plane shear lag factor, and the active shear resistance planes identified in the present work, this paper proposes a rational equation that is demonstrated to provide more accurate results compared to all the code equations in predicting the block shear capacities of bolted connections in G450 steel sheets subjected to concentric loading. The resistance factor of 0.8 for the proposed equation is computed with respect to the LRFD approach given in the North American specification for the design of cold-formed steel structures

Distribution and molecular detection of apple mosaic virus in apple and hazelnut in Turkey

Apple mosaic virus (ApMV) is one of the most important diseases limiting the production of hazelnut and apple in Turkey and the objectives of this research were to determine the convenient and reliable method for RNA isolation and also to determine primer pair for real time polymerase chain reaction (RT-PCR) detection of coat protein gene for Turkish ApMV isolates. Apple mosaic virus isolates were collected in 2007 to 2010 and the presence of the pathogen was detected by double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) and RT-PCR tests. Six different RNA extraction protocols and three primer pairs were applied in RT-PCR amplifications and 44 hazelnut and 15 apple ApMV isolates were obtained. All of the amplicons were subjected to enzymatic digestion with restriction endonuclease enzymes and phylogenetic analysis were performed according to the digestion profiles.Keywords: Apple mosaic virus, coat protein gene, hazelnutAfrican Journal of Biotechnology, Vol 13(31) 3144-314

Recovery of germanium and other valuable metals from zinc plant residues

The main purpose of this study was to characterize and to extract germanium from the copper cake of Cinkur Zinc Plant. The physical, chemical and mineralogical characterization of the ground copper cake sample obtained from Cinkur showed that it was 84% below 147 pin containing 700 ppm germanium. The copper cake also contained 15.33% Cu, 15.63% Zn, 1.66% Cd, 1.33% Ni, 0.64% Co, 0.35% Fe, 2.62% Pb, 12.6% As, 0.18% Sb and 3.42% SiO2. The mineralogical analysis indicated the complex nature of the copper cake which was mainly composed of metallic and oxidized phases containing copper, arsenic, zinc, cadmium, etc. The sulfuric acid leaching experiments were performed under the laboratory conditions. The optimum collective extraction of germanium and other valuable metals was obtained at a temperature range 60 to 85 degrees C for a leaching duration of 1 h with sulfuric acid concentration of 150 gpl and using a solid-liquid ratio 1/8 g/cc. Under these conditions, the recovery of germanium was 92.7% while the other metals were leached almost completely. The optimum selective leaching conditions of germanium was determined as half an hour leach duration, 1/8 g/cc solid-liquid ratio, 100 gpl sulfuric acid concentration and a temperature range 40 to 60 degrees C. Under these conditions the leach recovery of germanium was 78%. The dissolution's of other metals like cobalt, nickel, iron, copper, cadmium and arsenic were almost low. So, germanium would be separated more selectively at the following precipitation by tannin stage

Effect of temperature on magnetic properties of BaYxFe12-xO19 hexaferrites

Yttrium doped barium hexaferrites with chemical composition BaYxFe12-xO19 (0.0?x?1.0) were synthesized by facile ceramic route. The effect of the yttrium ion concentration on the temperature-dependent magnetic properties of the BaYxFe12-xO19 hexaferrites (0.0?x?1.0) has been investigated in the temperature range of 10–300 K and magnetic field of 50 kOe. The structural, morphological, compositional and magnetic properties of the products were investigated by using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and vibrating sample magnetometer (VSM) techniques, respectively. XRD patterns demonstrated pure, single phase hexagonal crystal. The average crystallite size of the samples varies in the range of 47–63 nm. SEM images indicated hexagonal platelet-like particles. EDX measurements confirmed the expected formula of BaYFe11O19 hexaferrite. It has been observed that the preferential site occupancy of the nonmagnetic yttrium ions strongly changes the magnetic properties. The saturation magnetization value close to the bulk one was measured as 62.62 and 88.21 emu/g for 300 and 10 K, respectively. It has been found from the magnetization measurements that the saturation magnetization reaches its maximum value at x=0.4 and then decreases with further increasing of the concentration (x). As the temperature goes up, the saturation magnetization decreases due to the weakening of superexchange interaction. The coercive field increases by about three times with increasing of the concentration from x=0.0 to 1.0 due to an increasing of anisotropy field and reaches the maximum value of 3556 Oe at x=1.0. © 2016 Elsevier Ltd and Techna Group S.r.l.Fatih Ã?niversitesi: P50031504_BThis work is supported by Fatih University under BAP grant number P50031504_B
