Stereotype Threat in U.S. Students Abroad: Negotiating American Identity in the Age of Trump
Authors: Goldstein Susan B. 
Published: May 2020

An underinvestigated and significant source of stress for U.S. student sojourners across racial/ethnic groups is exposure to stereotypes that target their American identity. This study built on the extensive research literature on stereotype threat to investigate U.S. students’ vulnerability and reactions to being the target of stereotypes. Stereotype threat occurs when one expects to be judged negatively based on stereotypes of one’s social group and feels at risk of confirming these stereotypes. An online questionnaire administered to 95 students studying abroad just prior to and following the 2016 U.S. presidential election assessed predictors of, and common responses to, stereotype threat. Multiple regression analysis identified participant gender, CQ-Motivation, and exposure to Trump-related stereotypes as significant predictors of stereotype threat. Exploratory analyses indicated possible responses to stereotype threat, including distancing from a U.S. American identity and altering one’s appearance and behavior to look less American. Implications for sojourner support and for future research are discussed.

ABSTRACT
Illicit substance use has been becoming the major global issue. In Indonesia, inmates imprisoned for illicit substance offences accounted for 40 percent of the total inmates. This study aimed to identify the effects of family psychoeducational therapies on inmates’ self esteem in the narcotics correctional facility. Quasi-experimental pre-post test with control group was employed in this study. Intervention group 1 received general nursing intervention whereas intervention group 2 received family psychoeducational therapies. This study involved 31 inmates for each group. Data were collected using Rosenberg Self Esteem Scale (RSES), and were analysed using repeated ANOVA dan independent t-tests. The study demonstrated that self esteem was significantly upper amongst those who received the combination of those two therapies compared to those who received general nursing intervention standalone (p < .005). This study suggested the implementation of both general nursing intervention and specialistic therapies, particularly family psychoeducational therapies to address the anxiety problems experienced by adolescent inmates suffering from illicit substance dependences.

NEUTRAL POINT CONNECTIONS IN MV POWER NETWORKS WITH GROUNDING ZIGZAG TRANSFORMERS – ANALYSIS AND SIMULATIONS
Authors: Bernadić Alen , Anane Zahira 
Published: May 2020

Treatment of transformer neutral point in middle-voltage (MV) networks become an important issue with increasing proportion of MV cables in power networks. As consequence, overall capacitance of MV network is increased and moreover earth fault currents magnitudes. In MV networks with feeding transformer winding in delta connection (isolated networks), that earth fault current increase requires forming of artificial ground point – a neutral connection point on a three-phase ungrounded power system. Grounding transformer use, in zigzag or delty-wye connection, is common, well-known solution for constructing neutral connection in power systems. Physical characteristics of grounding transformers, protection principles, short-circuit calculations with symmetrical components and simulation techniques are presented in this paper. Characteristical operational modalities of MV power networks are also revieved on practical examples.

Authors: Ugurlu Erginbay 
Published: May 2020

Energy is a fundamental factor for economic development. Although in recent years there is a development in studies on an energy economics they are focused on specific energy sources. In this study natural gas, electricity and oil consumption which are the energy sources that the greatest market share of world and Turkey are investigating. In this investigation multivariate linear regression model is used. MVR model is a system of linear regression equations having the same set of independent variables. In this model within-equation, linear restrictions are testable on an equation-by-equation basis using a standard F test. The aim of the study is estimating demand of these three energy sources which are mentioned above. For this purpose, the regression model estimated which has a natural gas, electricity and oil consumption as dependent variables and price of these sources, income and population as independent variables by using 2001:01-2010:06 monthly data. Except for oil prices, coefficients of the model are statistically significant in all models. Coefficients are interpreted economically and determined that supply and demand move peculiar to Turkish energy markets despite the general expectations.
STRATEGIC ROLE OF OIL PIPELINES IN EU ENERGY SUPPLY
Authors: Sekulić Gordana , Kovačević Dragan , Vrbić Damir , Veselica Vladislav , Kovačević Dominik 
Published: May 2020

The oil pipelines have a strategic importance in the energy supply of the European Union (EU), especially given the fact that in the next two decades the crude oil will continue to be a dominant energy source, accounting for approx. 30% of the primary energy consumption, along with a reduction in the petroleum product consumption and growth in renewables.
Europe has a widespread network of oil pipelines of approx. 22,5 thousand kilometres (without Russia), connecting refineries to import oil ports or to land-based crude oil sources. The refineries of the Central Eastern Europe are supplied mainly from the Druzhba oil pipeline. Recently, these refineries have diversified their crude oil supply routes and sources, by sea imports from the North Sea, the Middle East, Canada and others (Poland) or by the TAL – IKL oil pipelines (Czech Republic) and the JANAF oil pipeline (Hungary, Slovakia and the Czech Republic). Given the insufficient diversification of crude oil supply precisely of the Central Eastern European region, particularly the landlocked countries (and refineries respectively), the EU has envisaged, among the projects of common interests, also six connection oil pipelines with terminals. At the same time, they are the only pipelines planned to be constructed in Europe and financed by the oil companies’ funds.
The oil pipeline and storage companies, as well as other oil companies, have a social responsibility as regards the energy supply, yet also a responsibility as regards their successful performance and development, thus investing considerable funds into modernisations, upgrades, protection, safety and security, etc. The oil pipeline companies hastily modify their strategies by expanding business and becoming more and more transport-storage-energy oriented, and by investing in the flow reversal of oil pipelines and connection pipelines, storage capacities, as well as in enhancement of efficiency and flexibility of oil pipeline and storage infrastructures.

Stochastic Processes as the Origin of the Double Power-law Shape of the Quasar Luminosity Function
Authors: Ren Keven , Trenti Michele , Di Matteo Tiziana 
Published: May 2020

Abstract
The quasar luminosity function (QLF) offers insight into the early coevolution of black holes and galaxies. It has been characterized observationally up to redshift z ∼ 6 with clear evidence of a double power-law shape, in contrast to the Schechter-like form of the underlying dark-matter halo mass function. We investigate a physical origin for the difference in these distributions by considering the impact of stochasticity induced by the processes that determine the quasar luminosity for a given host halo and redshift. We employ a conditional luminosity function and construct the relation between median quasar magnitude versus halo mass

with log-normal in luminosity scatter Σ, and duty-cycle ϵ
DC, and focus on high redshift z ≳ 4. We show that, in order to reproduce the observed QLF, the Σ = 0 abundance matching requires all of the brightest quasars to be hosted in the rarest most massive dark-matter halos (with an increasing

in halo mass). Conversely, for Σ > 0 the brightest quasars can be overluminous outliers hosted in relatively common dark-matter halos. In this case, the median quasar magnitude versus halo mass relation, M
UV,c, flattens at the high-end, as expected in self-regulated growth due to feedback. We sample the parameter space of Σ and ϵ
DC and show that M
UV,c flattens above

for

. Models with ϵ
DC ∼ 1 instead require a high mass threshold close to

. We investigate the impact of ϵ
DC and Σ on measurements of clustering and find there is no luminosity dependence on clustering for Σ > 0.3, consistent with recent observations from Subaru HSC.
Simulating the Fermi Bubbles as Forward Shocks Driven by AGN Jets
Authors: Zhang Ruiyu , Guo Fulai 
Published: May 2020

Abstract
The Fermi bubbles are two giant bubbles in gamma-rays lying above and below the Galactic Center (GC). Despite numerous studies on the bubbles, their origin and emission mechanism remain elusive. Here we use a suite of hydrodynamic simulations to study the scenario where the cosmic rays (CRs) in the bubbles are mainly accelerated at the forward shocks driven by a pair of opposing jets from Sgr A*. We find that an active galactic nucleus (AGN) jet event that happened 5–6 Myr ago can naturally reproduce the bilobular morphology of the bubbles, and the postshock gas temperature in the bubbles is heated to ∼0.4 keV, consistent with recent X-ray observations. The forward shocks compress the hot halo gas, and at low latitudes, the compressed gas shows an X-shaped structure, naturally explaining the biconical X-ray structure in the ROSAT 1.5 keV map in both morphology and X-ray surface brightness. CR acceleration is most efficient in the head regions of the bubbles during the first 2 Myr. The opposing jets release a total energy of ∼1055 erg with an Eddington ratio of ∼10−3, which falls well in the range of the hot accretion flow mode for black holes. Our simulations further show that the forward shocks driven by spherical winds at the GC typically produce bubbles with much wider bases than observed and could not reproduce the biconical X-ray structure at low latitudes. This suggests that starburst or AGN winds are unlikely the origin of the bubbles in the shock scenario.
Pre-Service Teachers' Attitude on ELT Research
Authors: Kustati Martin , Al-Azmi Hidayat 
Published: May 2020

This paper reports on a research determining the attitudes of pre-service EFL teachersâ€™ attitude to research in English language teaching (ELT) in Indonesia. A mixed method was used in this study. A survey questionnaire was completed by 217 (F= 187, M=30) participants who enrolled in the fourth year of undergraduate teacher education. Then, interview was used to identify their problems in conducting the research. The participants acknowledged that they had positive attitudes towards research in ELT. Meanwhile, they had negative views about English department involvement in their research. While there were no significant sex differences in the attitudes to ELT research. The interview findings revealed that there were some factors that made them get difficulties in doing their research. The pedagogical implications of the study for the pre-service teachers include the need to be aware of the significant relationship between attitude and background in research practice and they should be trained formally on conducting and writing ELT research.
