Determinants of Perceived Stress in Adolescence: The Role of Personality Traits, Emotional Abilities, Trait Emotional Intelligence, Self-Efficacy, and Self-Esteem

The aim of the current study was to examine the explanatory power of personality traits, emotional abilities, trait emotional intelligence, self-efficacy, and self-esteem in predicting perceived stress in adolescents. The data were collected from 406 high school students, aged 18-22 years (Mage = 18.47, SD = 0.64). Perceived stress was assessed with the 10-item Perceived Stress Scale (PSS-10). Personality traits were measured with the Eysenck Personality Short Scale (EPQ-R-S), emotional abilities were assessed with two performance tests, the Emotional Intelligence Scale – Faces (SIE-T), and the Emotion Understanding Test (TRE), and trait emotional intelligence was measured with a selfreport questionnaire (the Schutte Emotional Intelligence Scale, SEIS). The Generalized Self-Efficacy Scale (GSES) and the Rosenberg Self-Esteem Scale (RSES) were also used. Results indicate that the strongest determinant of perceived stress in adolescents was high neuroticism. Perceived stress was also determined by low self-efficacy and self-esteem, as well as high extraversion and psychoticism. Women reported higher perceived stress than men. There also were differences in the determinants of perceived stress between graduate and nongraduate students. The obtained results suggest that the development of high self-esteem and high self-efficacy may contribute to perceptions of lower stress in adolescents and may be especially valuable for neurotic individuals and for women, who are more exposed to stress.
R2 Dark Matter

There is a non-trivial four-derivative extension of the gravitational spectrum that is free of ghosts and phenomenologically viable. It is the so called R2-gravity since it is defined by the only addition of a term proportional to the square of the scalar curvature. Just the presence of this term does not improve the ultraviolet behaviour of Einstein gravity but introduces one additional scalar degree of freedom that can account for the dark matter of our Universe.
Agricultural Academy EFFECT OF SALINITY ON RECOVERY OF RHIZOCTONIA SOLANI FROM INFECTED TOMATO ( SOLANUM LYCOPERSICON MILL )

Al-Hammouri, A. A. , J. Ibbini, E. Bsoul and S. Sanogo, 2017. Effect of salinity on recovery of Rhizoctonia solani from infected tomato (Solanum lycopersicon Mill). Bulg. J. Agric. Sci., 23 (5): 757–761 The effect of salinity levels in irrigation water on recovery of Rhizoctonia solani from tap roots of tomato plants was investigated in two experiments conducted under greenhouse conditions. Potted soil was infested with R. solani and subjected to four salinity levels of 0 (control), 3, 8, and 10-mS cm-1. Recovery of R. solani from segments of tomato tap roots was evaluated. Dry weight of above ground plant parts, fruit number, plant height, and several plant physiological parameters were measured. Response of R. solani to salinity was variable. However, little or no signifi cant differences were found among treatments with respect to all the variables measured.
Geographic distribution of family physicians in Japan and the United States: a cross-sectional international comparative study

Background: Family physicians are known to distribute more equally among the population than other physicians. The maturity of family medicine, i.e. the length of its history as a part of healthcare system and the population of qualified family medicine experts, may affect the distribution, but this has not been shown in the literature. This study compares the geographic distribution of family physicians in Japan and the United States (U.S.), both of which are developed countries without a physician allocation system by the public sector, but the two countries differ greatly in the maturity of family medicine as a clinical specialty.Methods: This is a cross-sectional international comparative study using publicly available online database on the number of physicians in Japan (Board-certification Database of Japan Primary Care Association, and Survey of Physicians, Dentists and Pharmacists by Ministry of Health, Labour and Welfare) and the U.S. (Area Resource File by Health Resources and Services Administration). The municipalities in Japan and counties in the U.S. were divided into quintile groups according to population density. The number of family physicians per unit population in each group of areas was calculated. The geographic distribution of all physicians in Japan was simulated assuming that the proportion of family physicians among all physicians in Japan (0.16%) was increased to that in the U.S (11.8%). Results: The distribution of family physicians in Japan noticeably shifted to the areas with the lowest population density. In contrast, family physicians in the U.S. distributed equally across areas. The distribution of physicians with other specialties (general internists, pediatricians, surgeons and obstetricians/gynecologists) shifted heavily to the areas with highest population density in both countries. The simulation analysis showed the geographic maldistribution of all physicians improved substantially if the proportion of family physicians in Japan increases to that in the U.S. Conclusion: The distribution of family physicians is more equal than other medical specialists, and the immaturity of family medicine can even lead to a rural-biased distribution. In a country with emerging family medicine such as Japan, increasing the number of family physicians may effectively mitigate the urban-rural imbalance of physician supply.
Intimacy with God and Coronavirus in Pakistan

Intimacy with God is at the heart of Islamic practice through prayer. Intimacy with fellow congregants became central to the worship practices promoted by religious leaders during the holy month of Ramadan even when social distancing was required because of the pandemic. This was, by and large, an economic matter. Clerics and mosques rely significantly on the income generated through collective worship, especially during Ramadan. This article provides an account of people’s sense of intimacy with God and fellow congregants during Ramadan and how it contributed to the spread of the coronavirus in Pakistan.
Green Skills

The catchword ‘green skills’ has been common parlance in policy circles for a while, yet there is little systematic empirical research to guide public intervention for meeting the demand for skills that will be needed to operate and develop green technology. The present paper proposes a data-driven methodology to identify green skills and to gauge the ways in which the demand for these competences responds to environmental regulation. Accordingly, we find that green skills are high-level analytical and technical know-how related to the design, production, management and monitoring of technology. The empirical analysis reveals that environmental regulation triggers technological and organizational changes that increase the demand for hard technical, engineering and scientific skills. Our analysis suggests also that this is not just a compositional change in skill demand due to job losses in sectors highly exposed to trade and regulation.
Experiments on Expectations in Macroeconomics and Finance

Expectations play a crucial role in nance, macroeconomics, monetary economics and fiscal policy. In the last decade a rapidly increasing number of laboratory experiments have been performed to study individual expectation formation, the interactions of individual forecasting rules and the aggregate macro behavior they co-create. The aim of this chapter is to provide a comprehensive literature survey on laboratory experiments on expectations in macroeconomics and finance. In particular, we discuss the extent to which expectations are rational or may be described by simple forecasting heuristics, at the individual as well as the aggregate level.
Page 1 of 25 Do Operations Management Principles Apply to Computing Centers ?

By analyzing large data sets on jobs processed in major computing centers, we study how operations management principles apply to these modern day processing plants. We show that Little’s Law on long term performance averages holds to computing centers, i.e. work-in-progress equals throughput rate multiplied by lead time. Contrary to traditional manufacturing principles, the law of variation does not hold to computing centers, as the more variation in job lead times the better the throughput and utilization of the system. We also show that as the utilization of the system increases lead times and work-in-progress increase, which complies with traditional manufacturing. In comparison with current computing center operations these results imply that better allocation of jobs could increase throughput and utilization, while less computing resources are needed, thus increasing the overall efficiency of the center. From a theoretical point of view, a system with close to zero set-up times, as in the case of computing centers, the law of variation does not hold. We observe that the more variation in job lead times and resource usage, the higher the throughput of the system.
Carbohydrate Intake Modulates the Effect of the ABCA 1R 230 C Variant on HDL Cholesterol Concentrations in Premenopausal Women 1 , 2

The R230C variant of the ATP-binding cassette transporter A1 (ABCA1) gene has been consistently associated with decreased HDL-cholesterol (HDL-C) concentrations in several studies in the Mexican mestizo population. However, information on how diet composition modifies the effect of the ABCA1-R230C variant on HDL-C concentrations is very scarce. The aim of the present study was to analyze whether the effect of ABCA1-R230C on HDL-C concentrations is modulated by dietary factors in a nationwide population sample of 3591 adults from the National Health and Nutrition Survey conducted by the State’s Employees’ Social Security and Social Services Institute. All participants answered a validated questionnaire to assess health status and weekly food consumption. Fasting blood samples were drawn for biochemical analysis and DNA extraction, and the ABCA1-R230C variant was genotyped using TaqMan assays. Statistical analyses consisted of simple linear and multiple regression modeling adjusting for age, BMI, smoking, and alcohol consumption. The overall C risk allele frequency was 9.3% and the variant was significantly associated with low HDL-C concentrations in both sexes. A significant negative correlation between carbohydrate consumption and HDL-C concentrations was observed in women bearing the R230C variant (P = 0.021) and a significant gene-diet interaction was found only in premenopausal women (P = 0.037). In conclusion, the effect of the ABCA1-R230C gene variant on HDL-C concentrations is modulated by carbohydrate intake in premenopausal women. This finding may help design optimized dietary interventions according to sex and ABCA1-R230C genotype. J. Nutr. 142: 278–283, 2012.
Educational Leader’s Adversity Quotient, Management Style, and Job Performance: Implications to School Leadership

The study examined the adversity quotient, school management style and job performance of public elementary school heads in Cabanatuan City, Philippines. Total population sampling was utilized among 38 public elementary school heads in the district. Anchored on Adversity Quotient Theory (Stoltz, 2000) and Situational Leadership Theory (Hersey & Blanchard, 2001), both processes measured how educational leader reacts and resolves within tough school related problems encountered. These lenses offered structure in looking at the four dimensions of adversity quotient in relation to leadership style. Survey questionnaire on Adversity Response Profile (ARP), Leadership Style, and Office/Individual Performance Commitment Response (OPCR) were utilized. With two-semester period of data consolidation, Pearson r product moment correlation assisted in the analysis of data. Results disclosed that, in adversity quotient and job performance, school heads having high degree of adversity quotient- control most likely to perform better in instructional leadership and quality standard for basic education program. Recommendations on the opportunity of assimilating adversity quotient and school management style in their current school head qualifications be considered to further improve organizational performance in the educational management system.
Bacteriological profile and antibiotic resistance pattern of urinary tract pathogens isolated at National Referral Laboratory, Ethiopian Public Health Institute

Background: Urinary Tract Infection (UTI) most commonly affects humans next to respiratory and gastro-intestinal infections. It is caused by various ranges of bacterial pathogens with varying patterns of antibiotic resistances. Objective: To determine the profile of bacterial pathogens causing Urinary Tract Infection and their antibiotic resistance patterns. Methods: This is a retrospective study that used data from Clinical Bacteriology and Mycology National Reference laboratory of the Ethiopian Public Health Institute (EPHI), January 2014 to December 2015. Information on patients’ demography and identified pathogens as well as their sensitivity pattern to various antibiotics are routinely documented in the laboratory registration book. The raw data was compiled and entered to spread sheet to compute proportion using Microsoft Excel and Multi-drug resistant strains were analyzed using SPSS Version 20. Results: The overall prevalence of urinary tract infection was 30.5 % (269 of 882). Of these, above two-thirds of the infection was in females (68 %, 183 of 269). Escherichia coli accounted about half of bacterial pathogens (48.3%, n= 130) and below one fifths were due to Klebseilla species (13%, n=35.). Among Gram positive isolates, coagulase negative Staphylococcus and Staphylococcus aureus account 12.8% (n=33) and 10.4 % (n= 28), respectively. Gram negative bacteria pathogens showed extreme resistance to ampicillin (96.7 %) and less resistant to amikacin (8.8 %) while the resistance rate of Gram positive bacteria isolated in this study range from16.2% (nitrofurantion) to 85.7 % (cotrimoxazole). Multidrug resistance was noted for Klebsiella spp (71 %), E. coli (55 %), Enterobacter spp (50%) and Staphylococcus aureus (25%) Conclusion: This study documented high prevalence of Urinary Tract Infection caused by Gram negative bacterial pathogens. These pathogens are also highly resistant to a range of commonly used antimicrobials with significant proportion of them being Multi-drug resistant (MDR). Therefore, we recommend regular surveillance and monitoring to be put in place that would eventually provide necessary information for decision makers.

A Generalized Dynamic Factor Model for the U.S. Port Sector

Although rarely available ports produce a polymorphic set of timely available monthly import, export, transport and labor utilization series, providing frequent snapshots of freight volumes either as being transferred between modes, or trans-shipped to secondary destinations. Utilizing monthly inflows and outflows of several cargo types as well as cruise passenger volumes from U.S ports, we: a) demonstrate the potential and the added value of information carried by common factors shaped by ports with respect to outlining the underlying forces of a national economy and b) provide competitive forecasts of disaggregate trade series from single ports (such as, e.g. outgoing or incoming TEUs) by exploiting factor dynamics, We test this concept in the context of Forni et al. (2005) one-sided generalized dynamic factor model, exploring the links between ports and the driving factors of the U.S. economy, as these are captured through its common and idiosyncratic components. Our model, employing 192 series from 31 major port complexes -covering 84.4% of TEUs and 60.1% of the dry bulk volume between 2005 and 2012-, displays a promising forecasting performance for individual ports and aggregate economic indicators versus benchmark models at 4-7 months ahead and explains a high fraction of the US GDP and Industrial Production indices variance.
Produced Water Desalination via Pervaporative Distillation

Herein, we report on the performance of a hybrid organic-ceramic hydrophilic pervaporation membrane applied in a vacuum membrane distillation operating mode to desalinate laboratory prepared saline waters and a hypersaline water modeled after a real oil and gas produced water. The rational for performing “pervaporative distillation” is that highly contaminated waters like produced water, reverse osmosis concentrates and industrial have high potential to foul and scale membranes, and for traditional porous membrane distillation membranes they can suffer pore-wetting and complete salt passage. In most of these processes, the hard to treat feed water is commonly softened and filtered prior to a desalination process. This study evaluates pervaporative distillation performance treating: (1) NaCl solutions from 10 to 240 g/L at crossflow Reynolds numbers from 300 to 4800 and feed-temperatures from 60 to 85 °C and (2) a real produced water composition chemically softened to reduce its high-scale forming mineral content. The pervaporative distillation process proved highly-effective at desalting all feed streams, consistently delivering <10 mg/L of dissolved solids in product water under all operating condition tested with reasonably high permeate fluxes (up to 23 LMH) at optimized operating conditions.
Missouri reservoirs in the Glacial Plains: evaluating small impoundments

Missouri reservoirs are located in a mid-contment ecotonal zone at the intersection of historic prairies and broad-leafed forests. Reservoir nutrients span the trophic state range and increase along a south-to-north axis across several distinct physiographic regions (JoNES et al. 2008a). Empirical analyses show this pattem is largely accounted for by cropland cover in the catchments (a surrogate for nutrient los s from agriculture) as modified by morphology and hydrology (JoNES et al. 2004, 2008b, 2009). These findings are consistent with limnological theory about the role ofhydrology and morphology moditying extemal nutrient loads to lakes. Most Missouri reservoirs were constructed within the past 50 years, but many are half that age. With few exceptions, land cover at the time of impoundment closely matched current conditions (JoNES et al. 2004, 2009). As such, nutrient loads were in place prior to creating these artificiallakes on the landscape. Reservoir age does not influence cross-system pattems for nutrients, suggesting that trophic state is largely
EFFECT OF LITTER SIZE AT BIRTH AND OF NUMBER OF SUCKLED KITS , ON THE MILK PRODUCTION IN TWO GENOTYPES OF RABBIT DOES RAISED IN ALGERIA

In a commercial rabbit production unit located in Tigzirt (Tizi-Ouzou, Algeria), 85 litters of two genotypes (42 white population WP and 43 synthetic strain SS) were divided in 3 classes according to the number of kits born alive: <6, 6-8, >8. Thanks to fostering and withdrawal of kits just after kindling within each class of kits born alive, litters were divided again into 3 suckling groups with the same limits of classes, which led to an experimental factorial design 2 x 3 x 3. During the 21 days after kindling, milk production of does increased with the number of the suckled kits (121, 160 and 194 g/d for the 3 classes, respectively). As against, milk production does not vary significantly depending on the number of kits born alive (being a mean of 158 g of milk / day). With identical number of kits born alive or suckled (7.1 on average), SS rabbit does had a higher milk production by 13% to that of WB genotype (P = 0.05). None of the 3 interactions between the three factors, taken in pairs was significant.
DURABILITY OF CONCRETE AND THE IOWA PORE INDEX TEST

An overview of the problem of D-cracking in portland cement concrete (PCC) is provided, and the Iowa pore index test for determining the quality of coarse aggregate for concrete is evaluated. The Iowa pore index test was developed to evaluate the durability of coarse aggregate. The test measures the amount of water that can be injected into oven-dried aggregate during a period from 1 to 15 min after application of 35 psi (241 kPa) of pressure. The test is very effective in identifying aggregates with substantial pore system of the 0.04- to 0.2-micron-diameter size and correlates very well with aggregate service records. Test results of nonhomogeneous samples can be misleading. Laboratory tests have shown that a small amount (15 percent) of unsound material in the coarse aggregate can produce nondurable concrete. Studies with the scanning electron microscope show that coarse aggregates associated with D-cracking are normally fine grained whereas durable aggregate is either coarse grained or extremely fine grained. The pore-size distribution of coarse aggregates was determined by using a mercury porosimeter. Aggregates associated with D-cracking exhibit a predominance of 0.04- to 0.2-micron-diameter pore sizes.

Auction econometrics by least squares

This paper proposes a method to structurally estimate an auction model using a variation of OLS, under commonly held assumptions in both auction theory and econometrics. In spite of its computational simplicity, the method applies to a wide variety of environments, including interdependent values in general, and certain forms of endogenous participation and bidder asymmetry. Furthermore, it can be used for hypotheses testing about the shape of the valuation distribution, valuation interdependence, or existence of bidder asymmetry.
Achieving Cooperation Under Privacy Concerns Wioletta Dziuda

Two players choose whether to cooperate on a project. Each of them is endowed with some evidence, and if both possess a sufficient amount then cooperation is profitable. In order to facilitate cooperation the players reveal evidence to one another. However, some players are concerned about privacy, and so revelation of evidence that does not result in cooperation
