Magnetic graphene sponge for the removal of methylene blue

Magnetic carbon nanomaterials have been widely adopted as adsorbents in water treatment, but the low adsorption capacities largely limit their practical applications. In this study, magnetic graphene sponge (Fe3O4-GS) was prepared by lyophilization for the adsorption of dye pollutant. The incorporation of Fe3O4 enabled the magnetic separation of Fe3O4-GS after the adsorption of methylene blue (MB). The adsorption capacity of Fe3O4-GS for MB was 526mg/g, much higher than those of the magnetic carbon nanoadsorbents in the literature. The adsorption kinetics of MB on Fe3O4-GS was moderately fast, which could be analyzed by the pseudo-second-order model and intraparticle diffusion model. The thermodynamics study revealed that the adsorption was driven by the increased randomness on the interface. The pH and ionic strength had meaningful influences on the adsorption capacity of Fe3O4-GS. The facile regeneration of Fe3O4-GS would definitely reduce its operating cost. The implications to the environmental applications of magnetic carbon nanoadsorbents are discussed.

Social Vision: Functional Forecasting and the Integration of Compound Social Cues.

For decades the study of social perception was largely compartmentalized by type of social cue: race, gender, emotion, eye gaze, body language, facial expression etc. This was partly due to good scientific practice (e.g., controlling for extraneous variability), and partly due to assumptions that each type of social cue was functionally distinct from others. Herein, we present a functional forecast approach to understanding compound social cue processing that emphasizes the importance of shared social affordances across various cues (see too Adams, Franklin, Nelson, & Stevenson, 2010; Adams & Nelson, 2011; Weisbuch & Adams, 2012). We review the traditional theories of emotion and face processing that argued for dissociable and noninteracting pathways (e.g., for specific emotional expressions, gaze, identity cues), as well as more recent evidence for combinatorial processing of social cues. We argue here that early, and presumably reflexive, visual integration of such cues is necessary for adaptive behavioral responding to others. In support of this claim, we review contemporary work that reveals a flexible visual system, one that readily incorporates meaningful contextual influences in even nonsocial visual processing, thereby establishing the functional and neuroanatomical bases necessary for compound social cue integration. Finally, we explicate three likely mechanisms driving such integration. Together, this work implicates a role for cognitive penetrability in visual perceptual abilities that have often been (and in some cases still are) ascribed to direct encapsulated perceptual processes.

사립유치원교사의 교사효능감과 의사소통능력이 직무스트레스에 미치는 영향

The purpose of this study was to identify the influence of private kindergarten teachers' teacher efficacy and communication competence on their job stress. The subjects in this study were 161 private kindergarten teachers working in kindergartens in Gyeong-gi province. For the research analysis, frequency, Cronbach's coefficient, and Pearson's correlation were calculated and regression analysis were conducted. The results are as follows. Firstly, it was revealed that personal teacher efficacy does have statistically meaningful negative influences on job stress as a whole as well as the sub-factors of job stress, but general teacher efficacy has meaningful negative influences only on the personal-related stress of the sub-factors. Secondly, communication competence has statistically meaningful negative influences on job stress as a whole as well as the sub-factors of job stress. Through this study, it is possible to provide a basic guideline to configure the subject content that enhance teacher efficacy and make them give full play to communication competence and develop a positive attitude for coping with job stress in a curriculum for private kindergarten teachers.

초임유아교사의 스트레스 대처방식이 역할수행에 미치는 영향에 대한 셀프리더십의 매개효과

본 연구는 초임유아교사의 스트레스 대처방식, 역할수행, 셀프리더십의 관계를 규명하기 위해 실시되었다. 전국의 유치원 및 어린이집에 재직 중인 491명의 초임교사를 대상으로 설문지를 통한 조사를 실시하였고, 스트레스 대처전략 질문지(박창순, 2005), 역할수행 질문지(박복매, 2011)와 셀프리더십 질문지(박동현, 2014)를 사용하였다. 결과 처리를 위해 빈도분석, 신뢰도 검증, Pearson의 적률상관분석, 회귀분석을 실시하였다. 연구결과 초임유아교사의 스트레스 대처방식 중 소극적인 대처방식은 역할수행에 영향을 미치지 않는 것으로 나타난 반면, 적극적 대처방식은 역할수행에 정적인 영향을 미쳤다. 또한 초임유아교사의 적극적 대처방식은 셀프리더십을 통해서도 역할수행에 정적인 영향을 미쳤다. 즉, 초임유아교사의 셀프리더십이 높을수록 교사가 경험하는 역할수행이 높아지는 결과가 나타났다. 이러한 경로는 셀프리더십이 초임유아교사의 역할수행에 대한 적극적 대처방식과 역할수행 간에 부분 매개역할을 하고 있음을 보여주는 결과이다. 본 연구결과를 통해 예비유아교사를 대상으로 한 교육과정 내에 셀프리더십 증진내용과 스트레스에 대처하는 능동적인 태도를 형성할 수 있는 교과내용을 구성하는데 기초정보를 제공할 수 있다. The purpose of this study was to identify the relationship among beginning early childhood teachers' stress coping strategies, role performance, and self leadership. The subjects in this study were 491 beginning early childhood teachers working in kindergarten and child care centers across the country. Stress coping strategies questionnaire(Chang-Soon Park, 2005) and role performance questionnaire(Bog-Mae Park, 2011), and self-leadership questionnaire(Dong-Hyen Park,2014) were used for this study. For the research analysis, frequency, Cronbach's <TEX>${\alpha}$</TEX> coefficient, and Pearson's correlation were calculated and regression analysis were conducted. The results are as follows. Firstly, it was revealed that passive stress coping strategies does not have statistically meaningful influences on role performance, but active stress coping strategies have statistically meaningful positive influences on role performance. Also, 491 beginning early childhood teachers' active stress coping strategies have statistically meaningful positive influences on role performance through the mediation of self leadership. That is, the results explain that the higher the self-leadership of beginning early childhood teachers is, the higher the role performance that they have experienced is. It shows that beginning early childhood teachers'self leadership mediates partially between active stress coping strategies and role performance. Through this study, it is possible to provide basic information to configure the subject content that enhance their self-leadership and develop active stress coping attitudes in a curriculum for beginning early childhood teachers.

The purpose of this study was to examine the relationship among child care teachers' role performance and burnout, and supervisors' support. The subjects in this study were 171 child care teachers working in Gyeonggi province. Role performance questionnaire, the perceived supervisor's support scale, and the perceived burnout scale were used for this study. For the research analysis, frequency, Cronbach's <TEX>${\alpha}$</TEX> coefficient, and Pearson's correlation were calculated and regression analysis were conducted. The results are as follows. Firstly, it was revealed that both child care teachers' role performance and the perceived supervisors' support had statistically negative significant correlations with child care teachers' burnout. Secondly, role performance had statistically meaningful negative influences on child care teachers' overall burnout. Training and teaching activities as a sub-variable of child care teachers' role performance had statistically meaningful negative influences on emotional exhaustion, a lack of feeling of personal accomplishment, and overall job burnout. Thirdly, supervisors' support also had statistically meaningful negative influences on burnout. Material support as the sub-variable had statistically meaningful negative influences on emotional exhaustion, dehumanization, a lack of feeling of personal accomplishment, and overall job burnout. Evaluative support had statistically meaningful and negative influences on dehumanization and a lack of feeling of personal accomplishment. Through the results of this study, it must be indicated that it needs to promote the support of the supervisor in the various aspects and to provide a way which child care teachers efficiently perform the role in order to reduce their burnout.

General Mental Ability and Entrepreneurial Behavior and Performance: A Meta-Analytic Review

In this study, the authors used meta-analytical techniques to examine the relationship of general mental ability (GMA) with entrepreneurial status, intentions, skills, and firm-level performance outcomes. Results indicated that GMA has little to no relationship with entrepreneurial status or intent, but moderate to large relationships with entrepreneurial skills and firm-level outcomes. The authors found considerable heterogeneity in effects sizes and tested several moderators, including country of study, gender of entrepreneurs, fluid versus crystallized intelligence, and study design, but found little support for these moderators having meaningful influences on effect sizes.

Task complexity matters: The influence of trait mindfulness on task and safety performance of nuclear power plant operators

People with high level of trait mindfulness are more likely to maintain an open and present-focused awareness and attention. Whereas a positive link between trait mindfulness and well-being has been established, its influence on real-world performance has not been fully addressed. In Study 1, we validated the Freiburg Mindfulness Inventory (FMI) in a Chinese sample (N=294) and found that a two-dimensional solution (a presence factor and an acceptance factor) best fit the data. In Study 2, using this validated scale, we directly investigated the influence of trait mindfulness on task and safety performance. In a sample of 136 Chinese nuclear power plant operators, it was found that trait mindfulness interacted with task complexity to influence performance. For high-complexity-task holders (the control room operators), the presence factor was positively related to their task and safety performance; for the low-complexity-task holders (the field operators), the presence factor had no influence on safety performance but a negative influence on task performance. The acceptance factor did not have any meaningful influences. These results suggest that the benefit of being mindful outweighs its cost for complex but not simple tasks. Implications are discussed.

The Future of Emotion Regulation Research

Emotion regulation has been conceptualized as a process by which individuals modify their emotional experiences, expressions, and physiology and the situations eliciting such emotions in order to produce appropriate responses to the ever-changing demands posed by the environment. Thus, context plays a central role in emotion regulation. This is particularly relevant to the work on emotion regulation in psychopathology, because psychological disorders are characterized by rigid responses to the environment. However, this recognition of the importance of context has appeared primarily in the theoretical realm, with the empirical work lagging behind. In this review, the author proposes an approach to systematically evaluate the contextual factors shaping emotion regulation. Such an approach consists of specifying the components that characterize emotion regulation and then systematically evaluating deviations within each of these components and their underlying dimensions. Initial guidelines for how to combine such dimensions and components in order to capture substantial and meaningful contextual influences are presented. This approach is offered to inspire theoretical and empirical work that it is hoped will result in the development of a more nuanced and sophisticated understanding of the relationship between context and emotion regulation.

KTX기장의 개인-환경적합성이 직무만족, 조직몰입 및 이직의도에 미치는 영향에 관한 연구

본 연구는 KTX기장의 개인-환경(직무,조직,동료)적합성이 직무만족, 조직몰입 및 이직의도에 미치는 영향과 개인-환경적합성과 이직의도간의 관계에서 직무만족과 조직몰입의 매개효과를 실증분석 하였다. 분석결과, 개인-환경적합성은 직무만족, 조직몰입 및 이직의도에 대부분 유의미한 영향을 미치는 것으로 나타났으나, 개인-직무적합성은 직무만족에, 개인-동료적합성은 직무만족과 이직의도에 각각 유의미한 영향을 미치지 못하는 것으로 나타났다. 직무만족 및 조직몰입의 매개효과 또한 대부분 매개효과가 있는 것으로 나타났으나, 개인-조직적합성과 이직의도간의 관계에서 직무만족의 매개효과가 없는 것으로 나타났다. 결론적으로 본 연구는 KTX기장의 이직의도를 파악하고 이를 예방하기 위해서는 전반적인 개인-환경적합성을 높임은 물론, 직무만족과 조직몰입 향상방안 마련이 중요하다는 사실을 시사하고 있다. This study analyzes the effects of the KTX driver's person-environment(job, organization, Coworker) fit on job satisfaction, organizational commitment and turnover intention. It, additionally, examines the mediating effect of job satisfaction and organizational commitment between person-environment fit and turnover intention. Consequence of the analysis indicates that person-environment fit has mostly meaningful influences on job satisfaction, organizational commitment and turnover intention. But person-job fit makes a meaningless impact on job satisfaction, and person-coworker fit also makes a meaningless impact on job satisfaction and turnover intention. The mediating effect of job satisfaction and organizational commitment is mostly effective, but the mediating effect of job satisfaction does not affect the relation between person-organization fit and turnover intention. In conclusion, this study implies that, in order to grasp KTX driver's turnover intention and to protect actual turnover, it is important to enhance job satisfaction and organizational commitment as well as to improve overall person-environment fit.

A social work study on measuring the impact of gender and marital status on stress: A case study of hydro-power employees

Article history: Received April 15, 2012 Received in Revised form May, 15, 2012 Accepted 6 June 2012 Available online June 11 2012 The study performs an empirical survey to measure the impact of stress among people with various gender and marital status in a hydropower unit located in city of Esfahan, Iran. The study performs the survey among all 81 people who were working for customer service section of this company and consists of two parts, in the first part; we gather all private information such as age, gender, education, job experience, etc. through seven important questions. In the second part of the survey, there were 66 questions, which included all the relevant factors impacting employees' stress. We implement two Levin and t-student tests to see whether gender or marital status has any meaningful influences on creating stress among people. The results indicate that gender has no meaningful impact on creating stress among employees who worked for this hydro plant except difficulty of job conditions. The other findings of this paper is that stress posed from management team had different impacts on employees with various marital status but there were no meaningful differences between married and single couples in terms of other factors posing stress such as unsuitable working conditions, fear of job stability or difficulty of job conditions. © 2012 Growing Science Ltd.

Is Culture Destiny? — An Empirical Analysis of Foreigners’ Litigation Performance Before the International Trade Commission

This study is the first to explore how culture influences a party’s choices and performance in international litigation. It analyzes three aspects of culture in international litigation: cultural barriers to the participation in litigation, cultural risk preferences, and the unique influences that major cultural zones have upon litigation. This study also expands upon the Priest-Klein model of case selection to facilitate analysis. This study uses logistic regression to analyze Section 337 investigations in the U.S. International Trade Commission (“ITC”). Cultural difference, measured by both social values and linguistics, is found to significantly impair every aspect of a foreign party’s performance. Respondents from the Confucian cultural zone are found to be much more likely to settle litigation. This study also finds an unexpected interplay between uncertainty avoidance and cultural heritage: uncertainty avoidance enhances litigation performance only for respondents from the Confucian cultural zone. Other variables such as the economic development level of the home society of a respondent, the time of the investigation, the number of home societies of respondents, and whether the respondent is foreign also lead to statistically significant conclusions. Variables that are not found to have meaningful influences are also presented. The finding of a cultural barrier to a certain extent exonerates U.S. adjudicators whom some prior studies have blamed for xenophobia bias. This article also reviews previous claims of bias on the part of the ITC and finds them unpersuasive. Foreign respondents actually outperform domestic respondents after cultural and other factors are considered. Statistical analysis suggests that the superior outcomes of foreign respondents can be explained by their attraction to weak cases.

Effects of the weld groove shape and geometry on residual stresses in dissimilar butt-welded pipes

The thermo mechanical behavior of the welding process was analyzed using the finite element technique to determine the residual stress magnitude and distribution in butt-welded pipes. An efficient user subroutine was developed in a finite element model to consider the effects of phase transformation in the analysis. The calculated results verified using the determined data presented by Deng for similar weld joints and measured data by the hole drilling technique for dissimilar weld joint. Good correspondence between the finite element results and experimental data infers that the computational procedure developed in this study is an effective method for residual stress prediction in dissimilar welded joints. The effects of pipe wall-thickness, weld groove angle and root opening distance on welding residual stresses in dissimilar butt-welded pipes were studied using the prepared finite element model. It is observed that the pipe wall-thickness has important influences on the residual stress magnitude and distribution. Meaningful influences from weld groove angles and root opening distances are observed on the axial residual stresses in the ferritic side.

Top-Down Management and Patrol Officers’ Attitudes About the Importance of Public Order Maintenance

Police organizations are inherently top down in their managerial style, and order maintenance policing—being a strategy adopted by top management and implemented by lower ranking personnel—may hit a roadblock that is typical in top-down organizations: Lower ranking personnel may not embrace the mission of order maintenance to the same extent that their superiors do. The present study compares attitudes about order maintenance policing across rank in an urban police department. The results indicate that patrol officers express significantly less support for public order maintenance relative to personnel of higher ranks; however, educational attainment and attachment to supervisors emerged as meaningful influences on attitude as well, which suggests that police managers and supervisors can improve lower ranking officers’ endorsement of top-down strategies like order maintenance through their supervisory and hiring practices.

Pure-tone auditory thresholds are not chronically elevated in multiple sclerosis.

Despite the fact that acute cases of multiple sclerosis (MS)-related pure-tone hearing loss have been reported in the literature, consensus is lacking as to the chronic influences of MS on pure-tone thresholds. Most studies examining such influences have been limited by small sample sizes, lack of statistical comparisons between patients and controls, and confounding of the hearing measure with influences from sex and age. To date, associations between pure-tone thresholds and central MS-related brain lesions have not been assessed. In this study, pure-tone thresholds ranging from 0.5 to 8 kHz were measured in 73 MS patients and 73 individually age- and gender-matched normal controls. In 63 MS patients, correlations were computed between the threshold values and MRI-determined lesion activity in 26 central brain regions. Although thresholds were strongly influenced by sex, age, and tonal frequency, no meaningful influences of MS were discerned. Moreover, no significant association between the threshold values and central MS-related lesion activity was evident in any brain region evaluated. This study, the largest on this topic to use carefully matched control subjects and the sole study to assess relationships between auditory thresholds and central MS-related lesions, strongly suggests that (a) MS is not chronically associated with pure-tone hearing loss and (b) pure-tone thresholds are unrelated to MS lesion activity in higher brain regions. These findings, along with general reports from the literature, support the concept that when MS-related hearing threshold deficits are found, they are episodic and primarily dependent on lesions within the eighth nerve or brainstem.

A Meta-Analysis of Antecedents and Consequences of Leader-Member Exchange

Although leader-member exchange (LMX) was identified in the literature nearly 40 years ago, a comprehensive empirical examination of its antecedents and consequences has not been conducted. The authors’ examination included 247 studies, containing 290 samples, and 21 antecedents and 16 consequences of LMX quality. Results indicated that while leader behaviors and perceptions, follower characteristics, interpersonal relationship characteristics, and contextual variables represent significant groups of LMX antecedents, leader variables explained the most variance in LMX quality. Moderator analyses revealed that the particular LMX scale, country of participants, and work setting studied did not produce meaningful influences on the relationships in the meta-analysis. However, power distance and individualism did moderate some of these relationships. To provide continuity with the LMX meta-analyses and conceptual reviews that have focused on LMX consequences, the authors tested a number of mediation models. The results demonstrated that LMX frequently plays a mediating role in the relationships where mediation could be tested.

Six-month repeated dose toxicity of orally administered metacavir in rhesus monkeys

Objective To explore the toxicities of metacavir, a novel deoxyguanosine analog with an anti-hepatitis B virus (HBV) potential, in a 6-month repeated dosing in rhesus monkeys. Methods Rhesus monkeys were divided into four groups with eight animals in each group. Metacavir or blank vehicles were given for up to 6-month, and then the animals were euthanized 3 and 6 months later. Biochemical and hematological parameters, general symptoms, ECG, serum antibodies, and tissue pathology were observed and recorded. Results No biologically meaningful influences on body weight, body temperature, ocular examination, ECG, and organ weight were observed. The main toxic effects included: obvious gastrointestinal toxicities were observed in metacavir 200 mg/kg group, in which animals experienced vomiting and decrease in food consumption. Along with the increase of dosing times, animals gradually tolerated the drug and all these effects gradually abated. Hematological damages included increased damage of red blood cells, decrease of red blood cell count and hemoglobin levels. Hepatic functions were also damaged at certain levels, including the decreases in total protein, albumin, and glucose and the fatty degeneration in hepatocytes. Mild stenosis and exfoliation of gastric and duodenal mucosa was observed. The mild necrosis and exfoliation of renal tubules epithelia was found 6 months after the start of dosing. All these toxic effects were dose dependent. Conclusion The main target organs of the toxic effects of metacavir are gastrointestinal tract, liver, blood, and kidneys. The no-observed-adverse-effect-level (NOAEL) of metacavir for rhesus monkey were considered to be 50 mg/kg/day.

The role of feedback, causal attributions, and self-efficacy in goal revision.

An important issue in work motivation is how, when, and why individuals revise their goals up or down over time. In the current study, the authors examine feedback, causal attributions, and self-efficacy in this process. Although self-efficacy has frequently been suggested as a key explanatory variable for goal revision, its role has yet to be directly evaluated. Additionally, although attributions have been shown to influence goal revision following failure, the extent to which attributions influence goal revision following success remains unclear. In the current study, the authors address these issues by experimentally manipulating goal progress via performance feedback and tracking the resulting changes in self-efficacy and goal revision over time. In so doing, the authors also address several interpretive ambiguities present in the existing research. Results support the hypothesized model, finding that performance feedback and attributions interactively influenced self-efficacy, which in turn influenced goal revision. These results suggest that interventions targeting attributions, and self-efficacy more directly, may have meaningful influences on goal setting and pursuit, particularly following feedback.

Psychosocial Aspects of Chronic Disease

Psychosocial issues are an understudied yet important concern in the overall health of hemodialysis (HD) patients. Stress is a concomitant of chronic illness and its treatment, and may have meaningful influences on psychological and medical outcomes. This article reviews the influences of psychopathology, social support, family issues, dialysis unit culture, and socioeconomic status on patients treated with center HD. Depressive affect and decreased perception of social support have been linked with mortality in several studies of ESRD patients. Decreased marital satisfaction, disturbances in family dynamics, and lower socioeconomic status (SES) have been associated with poorer health outcomes and can affect patients' perception of social support and depressive affect. Chronically ill ESRD patients who undergo treatment with constant interaction and observation by medical staff are potentially an ideal group for evaluation of the effects of stress and psychosocial factors on outcomes in those with chronic disease, as well as an excellent patient population for intervention to reduce morbidity and mortality. These interactions between potentially modifiable psychosocial risk factors for disease and medical aspects of illness form a paradigm for the study of interventions related to adjustment to chronic illness in the ESRD population.

Geostatistical analysis of regional differences in stem taper form of Pinus densiflora in central Korea

AbstractThis study verified regional differences in the stem form of Pinus densiflora Sieb. et Zucc. (red pine) and identified the relationship between stem form and climatic factors in the central region of the Korean peninsula. Regional differences in stem form index at tree base (butt) and top stem section were found. Compared to the stem form in the eastern uplands, the stem form in the western lowlands could be characterized by a more conical butt section and more cylindrical middle and upper section. Through geostatistical analysis of kriging and spatial regression, several climatic factors proved to exert a meaningful influence on stem taper form. On the stem form at the butt section, the precipitation during the late growing season exerts statistically significant effects. High precipitation during the growing season in the western lowland and coastal region causes the stem form at the butt section to be more tapered. On the stem form at the middle and upper section, temperature and precipitation during the growing season, and wind during the late growing season have statistically meaningful influences. High temperature, precipitation, and wind during the growing season in the western lowland and coastal region jointly influence the stem form at the middle and upper sections which result in more cylindrical profiles. This study can be considered an initial investigation into the factors controlling stem form variability in the central region of the Korean peninsula. The results can be used to develop more accurate regional stem taper models needed for reasonable management of red pine stands in different regions.
