As a kind of rapid filling hydraulic structure, geomembrane tube can effectively act as flood barriers and cofferdams for flood risk management. L-shaped block is used to support geomembrane tube to prevent it from rolling. The contact force between the L-shaped block and the geomembrane tube is analyzed by using particle flow code (PFC2D) software, and the overturning stability of the L-shaped block is calculated. The relationship between the key factors and the overturning stability was established. It is found that the central angle of the L-shaped block has little influence on the overturning stability. The overturning stability decreases with the increase of the initial pumping pressure. Keeping Lw/Lb unchanged, increasing Lb will improve the overturning stability where Lw and Lb are the width and the height of the Lshaped block. Under the ultimate water level, when 1.23 Lbcr < Lw≤1.55 Lbcr, the L-shaped block is in the state of overturning stability where Lbcr is the critical height of the L-shaped block. The initial pumping pressure is less than 0.152γL, the L-shaped block is in the state of overturning stability with Lw/Lbcr =1.0 where L is the cross-sectional perimeter of the geomembrane tube and γ is the unit weight of the filling liquid, on the contrary, Lw/Lbcr must be greater than 1 to ensure its overturning stability.

Purpose Using Vroom’s expectancy theory of motivation as a theoretical basis, this study aims to test the relationship between female entrepreneurial efficacy, entrepreneurial ambition and nascent entrepreneurial drive, accounting for the potential barriers of race and minority disadvantage. Design/methodology/approach The sample included 950 respondents comprising 213 Black women and 737 White women living in the state of Alabama, USA, who expressed an intention to starting their own business. Findings The results indicate that race and perceptions of minority disadvantage are perceived barriers in the mediated relationship between female entrepreneurial efficacy, entrepreneurial ambition and entrepreneurial drive. However, the findings suggest that, unlike race, minority disadvantage is not perceived as a significant factor in the mediated relationship between entrepreneurial confidence, entrepreneurial ambition and entrepreneurial drive. Research limitations/implications Limitations of this study include the lack of an experimental design and the use of cross-sectional data. Practical implications Results are discussed in terms of the context of the history of racial and gender discrimination within the state of Alabama, USA. Social implications The results show that the direct effects of minority disadvantage on entrepreneurial ambition are significantly higher for the Black women compared with the White women in our sample. Originality/value The results of this study show that the direct effects of minority disadvantage on entrepreneurial ambition are significantly higher for the Black women compared with the White women. For the subgroup of Black women, the greater the perception of minority disadvantage, the greater the entrepreneurial ambition reported.

Introduction: While mitigation procedures are needed to prevent the continuous spread of COVID-19, they may, in turn, negatively impact individuals’ mental health. Therefore, the current study aimed to investigate the relationships between loneliness, rumination, and depression, as well as the mediating role of rumination in the relationship between loneliness and depression in university students during the COVID-19 pandemic. Methods: A cross-sectional online survey was circulated, collecting a final sample of 288 university students (Mage = 22.01, SD = 3.45, range = 18–55, 75.7% female). Study variables were measured utilizing self-report questionnaires. Results: In line with the hypotheses, rumination partially mediated the relationship between loneliness and depression. Discussion: Therefore, ruminative thoughts may be one of the key factors contributing to lonely university students’ susceptibility to depressive symptoms during the COVID-19 pandemic.

Abstract Background The relationship between physician and patient is important topic in medical practice. How a physician dresses and addresses the patients are key factors that contribute to developing a rapport. This study aimed to investigate the psychiatrist's perspectives in order to facilitate an effective communication with patients.Methods This descriptive-analytic study was done on psychiatrists and psychiatric residents through a non-selective and non-randomized sampling method. Data were collected based on a questionnaire. Variables were such as age, sex, duration of practice as a psychiatrist, priority for male psychiatrist dress preference, priority for female psychiatrist dress preferences, priority for choosing a doctor from a gender perspective, priority for being addressed by patients, using the word of the gentleman or lady to address the patients, and the type of verbs and pronouns used by the psychiatrist and the patient during the interview in terms of the total number of verbs and pronouns. Subsequently, eight photographs of male and female physician’s coverage according to the in Iranian culture were shown to the participants and they were asked to choose one.Results A total of 77 psychiatrists participated in this study, of which 45 (58.4%) were male and 32 (41.6%) were female. In case of male psychiatrist’s coverage, 56 (72.7%) participants preferred suits; whereas in case of female psychiatrist’s coverages, 25 (32.5%) participants chose colored mantos and scarves, 22 (28.6%) selected black manteos and head dresses. Sixty three (81.8%) patients believed that the gender of the physician was not important in determining the treating physician. According to the type of addressing the psychiatrist by patients, 71 (92.2%) participants preferred to call the doctor's name followed by surname and 60 (77.9%) psychiatrists wanted patients to use the word "Mr. or Ms.” prior their names. Sixty three (81.8%) psychiatrists stated that it was better to use plural pronouns and verbs in interviewing patients, and 67 (87%) preferred their patients to use plural verbs to address them.Conclusions Psychiatrists’ appearance and the accuracy of the patient-referring type, based on what the physicians believe, along with the characteristics of the patients’ perspectives, help improving physician-patient relationship.

The Relationship

This article examines the relationship between indicators of poverty and inequality and the electoral behavior of the population. For the purpose of the study we use the results of elections of governors of Russian regions and the results of elections to the State Duma of the Russian Federation. The analysis was carried out on the basis of regional data for 2015–2019. Methods of cross-sectional regression analysis were used to reveal causal relationships. Based on the results of the analysis, it was revealed that the results of the election campaigns of the regional governors do not depend both on the level of poverty in the region and on the scale of socioeconomic inequality. At the same time, the scale of regional inequality had a significant impact on the regionallevel results of elections to the State Duma of the Russian Federation in 2016. Subsequently, the results of the election campaign in some regions turned out to be unpredictable.

Scholarly Attention

The nature of the relationship between the twin problem of poverty and unemployment has been unclear recently. Although the nature of the relationship has received more extensive scholarly attention worldwide and even in Nigeria, no study raised on the nature of its relationship in the region (state) which might produce an inverse relationship different from the proportionate obtained in previous studies. Hence the study on the relationship between poverty and unemployment in Niger state, Nigeria, using descriptive and a logistics regression model to analyze the 102 cross-sectional data randomly collected from the three geopolitical regions in the state. The result thus shows the existence of a proportionate relationship between poverty and unemployment, following the pattern of previous studies. The study thus recommends the actions of the policymakers in creating vocational skill programs to the aid-curb unemployment problem in the state. Accordingly, the increase in expenditure on education and the minimum wage as well recommended.

The Relationship

Employability emerged as a “new psychological contract” that may have beneficial effects on both individual and organisational outcomes. The study set out to investigate the relationship between perceived employability and employee well-being on the one hand and perceived employability and employees’ intention to leave on the other. The role of the state of the psychological contract, in terms of retaining employable employees while improving their well-being, was also investigated. Cross-sectional data were obtained from employees representing various organisations (N = 246). Contrary to expectations, structural equation modelling (SEM) indicated no significant relationship between perceived employability and well-being. Perceived employability was a significant predictor of employees’ intention to leave the organisation. Results also indicated that the state of the psychological contract does not moderate the relationship between perceived employability and employee well-being and their intention to leave, respectively. The study stresses the importance of fulfilling promises made to employees ensuring that promises are fair and continuing to fulfil promises. The importance of interventions on individual-level, to enhance well-being in the workplace, is also emphasised.

Analyze, in the necroscopic reports of the Death Verification Service of the State of Tocantins (SVO-TO), the records of biological samples collected for histopathological examination and records of autolysis in histopathological results and correlate them with records of causes of mortality and morbidity. Cross-sectional observational analytical study conducted in 494 autopsy reports completed and filed in SVO-TO, Brazil, between 2012 and 2016. Records of the number of biological samples collected for histopathology, number of autolysis, number of causes of mortality and number of causes of morbidity were extracted and identified. For the analysis of the relationship between the variables, descriptive and analytical statistics were used in SAS SYSTEM software. The mean number of mortality records was 5.72 ± 2.42 (CV 42.32%), causes of morbidity: 0.2 ± 0.5 (CV 251.46%), number of biological samples collected: 2.66 ± 1.13 (CV 42.59%), number of autolysis: 1.74 ± 1.05 (CV 60.06%). The number of mortality and morbidity diagnoses recorded in SVO reports increases the higher the number of samples collected by necropsies physicians. The number of biological samples collected by necropsy positively impacts the number of causes of mortality and morbidity. Collecting more than seven tissue samples by necropsy does not impact the number of causes of mortality and morbidity. The low numbers of autolysis records suggest efficacy in the collection of biological samples in SVO-TO.

Background: Deliberate self-harm (DSH) occurs with high frequency among clinical and nonclinical youth populations. Although depression has been consistently linked with the behavior, not all depressed individuals engage in DSH. Aims: The current study examined maladaptive coping strategies (i.e., self-blame, distancing, and self-isolation) as mediators between depression and DSH among undergraduate students. Methods: 202 students from undergraduate psychology courses at a private university in Southern California (77.7% women) completed anonymous self-report measures. Results: A hierarchical regression model found no differences in DSH history across demographic variables. Among coping variables, self-isolation alone was significantly related to DSH. A full meditational model was supported: Depressive symptoms were significantly related to DSH, but adding self-isolation to the model rendered the relationship nonsignificant. Limitations: The cross-sectional study design prevents determination of whether a casual relation exists between self-isolation and DSH, and obscures the direction of that relationship. Conclusions: Results suggest targeting self-isolation as a means of DSH prevention and intervention among nonclinical, youth populations.
