Junction Configuration Effects on the Photovoltaic Parameters of a-Si/CZTS Solar Cells

Due to increased energy intensive human activities resulting accelerated demand for electric power coupled with occurrence of natural disasters with increased frequency, intensity, and duration, it becomes essential to explore and advance renewable energy technology for sustainability of the society. Addressing the stated problem and providing a radical solution has been attempted in this study. To harvest the renewable energy, among variety of solar cells reported, a composite a-Si/CZTS photovoltaic devices has not yet been investigated. The calculated parameters for solar cell based on the new array of layers consisting of a-Si/CZTS are reported in this study. The variation of i) solar cell efficiency as a function of CZTS layer thickness, temperature, acceptor, and donor defect concentration; ii) variation of the open circuit current density as a function of temperature, open circuit voltage; iii) variation of open circuit voltage as a function of the thickness of the CZTS layer has been determined. There has been no reported study on a-Si/CZTS configuration-based solar cell, analysis of the parameters, and study to address the challenges imped efficiency of the photovoltaic device and the same has been discussed in this work. The value of the SnO2/a-Si/CZTS solar cells obtained from the simulation is 23.9 %.

Workplace Incivility and Job Satisfaction

Workplace incivility is common in organizations across the world and can have negative effects on individuals and organizations. The purpose of the reported study is to examine the effects of supervisor and coworker incivility on job satisfaction and examines emotion management as a mediator of these relationships. Data from 268 working adults were collected by survey battery and analyzed via a number of multivariate techniques. The model was supported in that both supervisor and coworker incivility had strong direct negative effects on emotion management and job satisfaction, and emotion management partially mediated the incivility-job satisfaction relationship. With supervisor and coworker incivility, the participants reported lower levels of job satisfaction. However, the participants' emotion management mitigated the negative effect of incivility on job satisfaction partially. The findings suggest that organizations need to be aware of the unfavorable consequences of incivility. Organizations need to discover ways to reduce incivility and implement efforts to help employees develop positive emotional management strategies. These actions may help reduce the negative influences of incivility on important organizational outcomes like job satisfaction.

The Effect of Wellness Programs on Long-Term Contract Employees' Workplace Stress, Absenteeism, and Presenteeism

The quasi-experimental study reported in the present article is aimed at increasing the understanding of the effects of long-term contract employees participating in wellness programs. The reported study examines the effect (if any) that a wellness program has on workplace stress, absenteeism, and presenteeism for long-term contract employees participating in a wellness program. A one group pretest-posttest design was used. Convenience sampling was conducted in a hospital in the New York City Metro area. Data was collected from 19 participants. Paired sample t-test and a Wilcoxon signed-rank test were used to determine if there was a significant statistical difference before and after a dance aerobic exercise intervention. The instruments used to gather data were the Perceived Stress Scale (PSS) and the World Health Organization Health Performance Questionnaire (HPQ). The results indicated a statistical difference for workplace stress, but no statistical difference for absenteeism and presenteeism.

Analysis Minimal Exchange Structures and General Exchange Structure in English Classroom Interaction Found in Youtube

This research reported study about analysis minimal exchange structures and general exchange structure in English classroom interaction found in you tube, (from mujikuy channel : asking and giving information about berbasis ganre in x class). This study direct to analysis the element of minimal exchange structures and general exchanges structures in English classroom interaction find in you tube. The data is the clauses obtained from conversation among teacher and students of X grade during English classroom learning process that find in you tube from (Mujikuy channel : asking and giving information about berbasis ganre in x class). This study uses theory of Halliday (1994) by qualitative descriptive method. The result shows that there are three (3) types of act as the element of exchange structures: Initiating, Responding,and Following-Up (I-R-F). Minimal exchange structure consists of: Initiating-Responding (I-R) or Initiating-Responding-Following Up (I-R-F). General structure of exchange in classroom situation consists of: greeting, giving order, giving information, asking question, and closing. In the learning process, things do not always go well. When the learning process students sometimes do not respond to conversations or instructions given by the teacher. Therefore teachers must take initiatives such as providing information, asking questions, and giving instructions. So that the learning process becomes more efficient. This study shows that the teacher has the authority to regulate learning activities

“Few people can have seen it” – an investigation into an allegedly non-normative construction with can and the perfect infinitive form

This article discusses an investigation into the English modal predicate with can and the perfect infinitive form of the main verb. The study uses language samples excerpted from The Corpus of Contemporary American English, as well as selected data from The Corpus of Historical American English and The British National Corpus. English grammars tend not to discuss can with the perfect infinitive form, which can give an impression that it does not exist. Nevertheless, the reported study confirms that can with the perfect infinitive form is present in both American and British Englishes, mainly in formal, written communication. In the US, it was used already at the beginning of the 19th century. Furthermore, can with the perfect infinitive form expresses either the speaker’s reasoning about a hypothetical past situation or speaker’s certainty that a situation did not take place in the past. Thus, can interacts with the perfect and yields epistemic readings. Additionally, subject negation extends its scope over the proposition. The propositional negation interacts with can, thus producing the meaning of speaker’s certainty. Finally, the findings of the study are used to determine the norms which may underlie the modal predicate with can and the perfect infinitive form. “Few people can have seen it” – badanie rzekomo nienormatywnej konstrukcji z czasownikiem can i formą bezokolicznika perfect Streszczenie: Artykuł omawia badanie angielskiego orzeczenia modalnego z czasownikiem can i formą bezokolicznika perfect czasownika głównego. W badaniu wykorzystano próbki języka z korpusu The Corpus of Contemporary American English oraz wybrane dane z korpusów: The Corpus of Historical American English i The British National Corpus. Gramatyki języka angielskiego zwykle nie omawiają can z perfectem, co może sprawiać wrażenie, że ta konstrukcja nie istnieje. Niemniej, opisane badanie potwierdziło obecność can z perfectem w angielszczyźnie zarówno amerykańskiej jak i brytyjskiej, zwłaszcza w oficjalnej komunikacji pisanej. Użycie tej konstrukcji w Stanach Zjednoczonych zarejestrowano już na początku XIX w. Can z perfectem wyraża wnioskowanie mówiącego odnośnie hipotetycznej sytuacji z przeszłości lub pewność nadawcy, że sytuacja nie wystąpiła w przeszłości. Zatem can wchodzi w interakcję z perfectem i w efekcie wyraża znaczenia epistemiczne. Nadto, negacja podmiotu obejmuje swym zasięgiem cały sąd logiczny i wchodzi w interakcję z can, w wyniku czego powstaje znaczenie pewności mówiącego. Na koniec określono normy, które mogły były przyczynić się do powstania orzeczenia modalnego z can i perfectem.

Do Internet Penetration and Online Censorship Levels Affect Long-Term Repression Success in Street Protest Prevention?

This research paper aims at learning whether Internet penetration and online censorship affect repression against civil society organization (CSO) capacity to prevent street protest events and/or reduce protest participant numbers in the long term. Although there is a large corpus of studies on the consequences of the Internet and social media development for street protest mobilization, there is little empirical research on whether offline CSO repression works in the age of the Internet and whether this new repression impact is modified by attempts to organize online censorship. I tried to solve this problem with large-N cross-national datasets on protest participation, CSO repression and online censorship as well as on the share of Internet users from 1990 to 2018. I propose a set of hypotheses claiming that repression has a negative unconditional effect on street protest probability and protester numbers, that the Internet penetration makes repression effect less negative or more positive, and that online censorship transforms repression impact into more negative and less positive. I test these hypotheses with pooled linear and logistic regressions weighted by inverse probability of loss to follow-up. The results demonstrate that when the repression effect exists, an uncensored Internet makes the weak repression effect positive and transforms highly severe repression effects from negative to null. Online censorship at a high level of Internet use only removes the positive effect of weak repression. Acknowledgments: The reported study was funded by RFBR and EISR, project number 21-011-32120.

Passive Suicidal Ideation in Childhood

Background: A growing body of empirical research shows that suicidal behaviors are prevalent in childhood. Yet, few studies have examined risk factors related to suicidal ideation (SI) among children aged 12 and younger. Aims: The current study addresses this gap. Method: A questionnaire was filled out by 1,350 Flemish primary caregivers (94.7% mothers) of 9-year-old children (50.4% boys, Mage = 9.45). Their responses were analyzed using logistic regression and independent samples t tests. Results: The presence of passive SI was reported in 10.5% of the children. A psychiatric, developmental, or behavioral condition (or multiple conditions), a learning disorder, impulsivity, aggression, and experiencing multiple stressful family life events were discovered as potential risk factors of passive SI in childhood. Limitations: The cross-sectional nature of this study meant that causality could not be inferred. In addition, it was based on reports of primary caregivers, rather than on reports from the children themselves. Conclusion: These new empirical findings can be used for the development of prevention programs and be taken into account in risk assessments of SI in clinical practice. Confirmation of our findings in a longitudinal child-reported study is needed.

Ecology-oriented social entrepreneurship: analysis of waste management legal regulation in Russia

The article deals with the main issues of municipal and industrial waste management legal regulation. The authors substantiate the idea that waste management entrepreneurs are environmental entrepreneurs, which in turn belong to social entrepreneurship. The relevance of legal research on the regulation of environmental-oriented social entrepreneurship lies in the fact that the system of legal regulation of environmental entrepreneurship has not been formed. Moreover, environmental entrepreneurship is not classified as social entrepreneurship. The purpose of the article is to substantiate the concept according to which entrepreneurial activity in the field of waste recycling and environmental protection should be considered through the prism of social entrepreneurship. The leading approach is dialectics, analysis, synthesis, deduction, formal legal method and comparative legal method. Conclusions: The performed analysis can contribute to the creation of developed environmental-entrepreneurial relations in Russia, which is achieved by building a verified conceptual and categorical apparatus, defining a model of legal regulation. Legislative regulation related to waste management is new, unsystematic, declarative and sometimes contradictory. To implement an effective waste management system, it is necessary to create an open and understandable waste management system, where citizens, legal entities and government bodies will be involved and motivated for its implementation. It is required to exclude the creation of intermediate links, such as regional operators, since their existence only causes a negative reaction from society.

Gender differences in videoed accounts of victim blaming for revenge porn for self-taken and stealth-taken sexually explicit images and videos

Using video recounts from revenge porn victims, this study explores whether levels of victim blaming differs for the sharing of self- and stealth-taken sexually explicit images and videos. Building on previous work which has demonstrated victim blame for both self- and stealth generated images in occurrences of revenge porn (Zvi & Schechory-Bitton, 2020), the reported study presents an original and ecologically valid methodological approach whereby 342 (76 male, 266 female) participants (Mage = 39.27, SD = 11.70) from the UK watched videoed accounts of real experiences of falling victim to revenge porn, rather than using text based, often fictional, vignettes to attribute blame which dominate studies in this area. All data was collected in 2019. The results demonstrated that significantly more blame was assigned to victims when participants were indirectly rather than directly asked who was to blame for the occurrence of revenge porn, supporting the notion of an unconscious processing bias in attributing blame. More blame was also assigned to those victims who themselves generated the material compared to when it had been acquired without their awareness by a perpetrator, suggesting the cognitive bias to be in line with a just world hypothesis. Male participants were more likely to blame a victim than were female participants, although sex of victim and mode of shared sexually-explicit material (video or image) did not appear to affect levels of victim-blame. Findings are considered in terms of extant research and the need for future work in the area of victim blame and revenge pornography.

Non-cancer to anti-cancer: investigation of human ether-a-go-go-related gene potassium channel inhibitors as potential therapeutics

Background The expression of hERG K+ channels is observed in various cancer cells including epithelial, neuronal, leukemic, and connective tissue. The role of hERG potassium channels in regulating the growth and death of cancer cells include cell proliferation, survival, secretion of proangiogenic factors, invasiveness, and metastasis. Methods In the reported study, an attempt has been made to investigate some non-cancer hERG blockers as potential cancer therapeutics using a computational drug repurposing strategy. Preliminary investigation for hERG blockers/non-blockers has identified 26 potential clinically approved compounds for further studies using molecular modeling. Results The interactions at the binding pockets have been investigated along with the prioritization based on the binding score. Some of the identified potential hERG inhibitors, i.e., Bromocriptine, Darglitazone, and Troglitazone, have been investigated to derive the mechanism of cancer inhibition. Conclusions The proposed mechanism for anti-cancer properties via hERG blocking for some of the potential compounds is required to be explored using other experimental methodologies. The drug repurposing approach applied to investigate anti-cancer therapeutics may direct to provide a therapeutic solution to late-stage cancer and benefit a significant population of patients.
