Cyberbullying Among Tweens in the United States: Prevalence, Impact, and Helping Behaviors

The goal of this study was to provide key prevalence rates for experiences with cyberbullying among tweens (children between the ages of 9 and 12 years old). We were also interested in the extent to which tweens engaged in helping behaviors when they observed cyberbullying. American tweens (n = 1034; mean age = 10.52, SD = 1.12) completed an online survey in which they reported on their experience with cyberbullying victimization, offending, and witnessing. Respondents were also asked how being cyberbullied made them feel, and to describe if they helped when they observed online mistreatment. Results revealed that about one in five tweens has been exposed to cyberbullying as a witness, a target, or an aggressor. This population has been historically understudied when it comes to their online experiences, and these findings highlight the need for deeper inquiry as well as additional guidance and support.
Digital Issue Movements: Political Repertoires and Drivers of Participation among Belgian Youth in the Context of ‘School Strike for Climate’

It often remains unclear how young citizens are combining various forms of political participation, as well as why they choose some over others, especially within a single-issue movement. Moreover, little is known about how social networking sites (SNS) fit into the political repertoires of citizens. Therefore, this study explores youths’ political participation patterns in the context of the 2019 youth-led climate strikes. We rely on data from a paper and pencil survey among 498 high school students in Belgium. To identify different types of activists, the study used latent class analysis (LCA). In addition, a multinomial logistic regression was conducted to assess how identified participation types differ from each other. Four different participation repertoires regarding the climate issue were identified, each distinctive in the way they rely on different forms of political participation. In addition, membership to each of the different classes is associated with a unique set of characteristics (in terms of political efficacies, climate issue involvement, and online expression motives). The article shows how SNS make up a crucial part of youths’ issue-specific participation patterns and sheds light on the mechanisms underlying their participation choices within the climate movement.
Evaluating Drivers of Fintech Adoption in the Netherlands

The development of smartphones and mobile internet technologies has promoted the development of mobile payments worldwide. The core purpose of this study is to ascertain what the main factors are which affect Dutch customers’ adoption and experience of mobile payments. This study first addresses the concepts of mobile payments and customer experience and then explores the current Dutch financial and banking systems, before attempting to understand the recent researches worldwide on mobile payments. Based on quantitative research methods, the study examines the factors that influence the adoption and experience of mobile payments and the impacts of the COVID-19 outbreak on payment methods due to social distancing rules in the Netherlands. It finds that perceived ease of use, perceived usefulness, safety and trust are the main factors that affect the adoption of mobile payments, and mobile-payment providers need to improve technical protection and offer some benefits to boost the mobile-payment business. The COVID-19 outbreak has caused the decline of cash payments and the increase of contactless payments in the Netherlands; mobile payments ensure people’s health and help slow down the spread of the virus.
Spatio-Temporal Analysis of the Hepatitis B Prevalence in Iranian Blood Donors from 2000 to 2016 at National and Provincial Level

Background: High risk blood transfusions can cause a lot of financial and psychological burden to the community. The prevalence of Hepatitis B is useful for evaluating the blood products’ safety and donor selection methods. We aimed to predict the prevalence of hepatitis B in Iranian blood donors from 2000–2016. Methods: Positive cases of hepatitis B from 2006 to 2014 were collected from Iranian Blood Transfusion Organization. This database was classified according to the age, provinces, and type of donation. Data was not existed in all subnational levels and all years, therefore, for predicting the hepatitis B prevalence, two separate, Spatio-temporal and mixed model (GLMM) were developed. Results: At the national level, the hepatitis B prevalence declined from 0.69 (0.51 to 0.90) in 2000 to 0.27 (0.21 to 0.33) in 2016. In first-time, regular, and repeated donors, this prevalence declined from 2.31 (1.74 to 2.31), 0.26 (0.19 to 0.34), and 0.51 (0.38 to 0.68) in 2000 to 0.87 (0.69 to 1.09), 0.09 (0.07 to 0.12), and 0.19 (0.14 to 0.24) in 2016. At the provincial level, the highest and lowest prevalence in 2016 was observed in North Khorasan and Gilan. With increasing age, the average prevalence of hepatitis B, increased. Conclusion: Prevalence of hepatitis B in Iranian blood donors has been reduced significantly over 17 years, but still new cases of hepatitis B are reported. By precise monitoring the donor selection process and implementing more sensitive laboratory screening, we can reduce the risk of new infectious agents.
COVID-19 and Changes in Social Habits. Restaurant Terraces, a Booming Space in Cities. The Case of Madrid

The COVID-19 pandemic and the fear experienced by some of the population, along with the lack of mobility due to the restrictions imposed, has modified the social behaviour of Spaniards. This has had a significant effect on the hospitality sector, viewed as being an economic and social driver in Spain. From the analysis of data collected in two of our own non-probabilistic surveys (N ~ 8400 and N ~ 2000), we show how, during the first six months of the pandemic, Spaniards notably reduced their consumption in bars and restaurants, also preferring outdoor spaces to spaces inside. The restaurant sector has needed to adapt to this situation and, with the support of the authorities (regional and local governments), new terraces have been allowed on pavements and public parking spaces, modifying the appearance of the streets of main towns and cities. This study, focused on the city of Madrid, analyses the singular causes that have prompted this significant impact on this particular city, albeit with an uneven spatial distribution. It seems likely that the new measures will leave their mark and some of the changes will remain. The positive response to these changes from the residents of Madrid has ensured the issue is being widely debated in the public arena.
Facilitating and Assessing Academic Writing to Graduate Students in a Pilot English for Academic Purposes Course: An Activity Theoretical Perspective

This paper reports on a pilot course responding to facilitating academic writing for an academic writing program implemented at a provincial key university in China. Taken from an activity theoretical perspective, it discusses the practical experience collected during a pilot process of designing, implementing, and assessing a genre-based approach to facilitating graduate students’ academic writing and assessing their academic writing competence. It argues that it is essential to take varied student interests into account in the structuring, delivery, and assessment to ensure academic success and that EAP programs are fruitful places for nurturing academic writing.
Focus of societal responsibility in the vision and mission statements of the United States pharmacy schools/ colleges

Objective: To assess the prevalence of societal responsibility languages and themes on education, research, and professional service in pharmacy programmes’ vision and mission statements. Methods: The authors collected the vision and mission statements of 142 pharmacy programmes by visiting each programme’s website. The statements were compiled and uploaded in NVivo 12. Deductive qualitative analysis and a topic extraction method with embedded principal component analysis (WordStat 8) were used to identify thematic dimensions of the statements. The number of programmes citing the respective themes were recorded. A Chi-square test was used to statistically analyse the prevalence of themes between the programme categories. Results: Education, research, professional practice, and societal service emerged as prominent themes. The prevalence of research, professional practice, and leadership themes was significantly higher in the vision statements of public programmes than private programmes. In the mission statements, the citation of a research theme was significantly higher in public programmes than private programmes. The citations of serving the diverse population and underserved population were very limited in the vision (6% and 5%) and mission statements (11% and 6%). Topic analysis conformed to the identified prominent themes and lack of societal responsibility theme in the mission statements. Conclusions: The prominent themes included education, research, and professional service to society at large. There is a distinctive lack of citations of societal responsibility towards underserved populations in the vision and mission statements.
Theoretical Analysis of the Effect of the Interfacial MoSe2 Layer in CIGS-Based Solar Cells

The aim of this work is to analyze the influence of the interfacial MoSe2 layer on the performance of a /n-ZnO/i-ZnO/n-Zn(O,S)/p-CIGS/p+-MoSe2/Mo/SLG solar cell. In this investigation, the numerical simulation software AFORS-HET is used to calculate the electrical characteristics of the cell with and without this MoSe2 layer. Different reported experimental works have highlighted the presence of a thin-film MoSe2 layer at the CIGS/Mo contact interface. Under a tunneling effect, this MoSe2 layer transforms the Schottky CIGS/Mo contact nature into a quasi-ohmic one. Owing to a heavily p-doping, the MoSe2 thin layer allows better transport of majority carrier, tunneling them from CIGS to Mo. Moreover, the bandgap of MoSe2 is wider than that of the CIGS absorbing layer, such that an electric field is generated close to the back surface. The presence of this electric field reduces carrier recombination at the interface. Under these conditions, we examined the performance of the cell with and without MoSe2 layer. When the thickness of the CIGS absorber is in the range from 3.5 μm down to 1.5 μm, the efficiency of the cell with a MoSe2 interfacial layer remains almost constant, about 24.6%, while that of the MoSe2-free solar cell decreases from 24.6% to 23.4%. Besides, a Schottky barrier height larger than 0.45 eV severely affects the fill factor and open circuit voltage of the solar cell with MoSe2 interface layer compared to the MoSe2-free solar cell.
Beyond the glass ceiling: an exploration of the experiences of female corporate organizational leaders in Ghana

ABSTRACT Although an increase in the inclusion of women in the global labor market has been reported in recent times, existing literature show that women are still heavily underrepresented in organizational leadership positions. Many studies in this area mainly focused on perceived barriers to women’s ascend to leadership positions, while little attention is paid to insights into the lived experiences of women who have already managed to assume leadership positions. This study was conducted to plug this gap in the literature. We interviewed 10 women corporate organizational leaders in Ghana to share their lived experiences as female leaders within the Ghanaian context. Our findings reveal that women still face several challenges even after breaking the glass ceiling to attain leadership positions in corporate organizations in Ghana. The main challenges were raised around the issue of gender, discrimination, age, their roles as mothers and wives. On the other hand, their positions also came with benefits and opportunities such as improved financial status, a command for respect as well as increasing their social and business networking capacity. More importantly, age although a disadvantage for the young women leaders, it was seen as a resource for older women as it enhances their respect and seen as performance of motherhood roles in this Ghanaian context. The study concludes that although women leaders’ experiences are largely negative, older women leaders seemed to utilize their positions actively and creatively and perform pseudo-motherhood roles which in turn helps them in the performance of their leadership roles.

Test your understanding with the exercises provided and discover connections to a wide variety of research areas in mathematics, theoretical physics, and computer science, such as conformal invariance, determinantal point processes, Gibbs measures, high-dimensional random sampling, symmetric functions, and variational problems.
Crisis, Rhetoric and Right-Wing Populist Incumbency: An Analysis of Donald Trump's Tweets and Press Briefings

Abstract How do right-wing-populist incumbents navigate rhetorical strategic choices when they seek to manage external crises? Relevant literature has paid increasing attention to the role of ‘crisis’ in boosting the electoral success of right-wing populist candidates. We know a lot less about the rhetorical strategies used by right-wing populist incumbents seeking re-election. We draw on literatures on populism, crisis management and political rhetoric to conceptualize the rhetorical strategic choices of right-wing populist incumbents in times of crisis. We propose a framework for the choice of rhetorical strategy available to right-wing populist incumbents and illustrate it with a qualitative content analysis of Trump's tweets and White House press briefings during the first months of the COVID-19 pandemic. We find limited rhetorical adaptation to crisis and high degrees of continuity with previous rhetoric grounded in right-wing populism. This challenges prevalent assumptions regarding the likelihood of incumbent rhetorical flexibility in the face of crisis.
Bioactive Secondary Metabolites from Marine Streptomyces griseorubens f8: Isolation, Identification and Biological Activity Assay

Marine actinomycetes are a potential source of a wide variety of bioactive natural products. Herein, four cyclic dipeptides, namely, cyclo(L-Val-L-Pro) (compound 1), cyclo(L-Pro-L-Leu) (compound 2), cyclo(L-Pro-L-Tyr) (compound 3) and cyclo(L-Pro-L-Phe) (compound 5), and an N-acetyltyramine (compound 4) were first isolated and identified as products of the marine Streptomyces griseorubens f8. Compounds 3 and 5 exhibit antibacterial activity against Staphylococcus aureus, Klebsiella aerogenes and Proteus vulgaris. The minimum inhibitory concentrations (MICs) against Staphylococcus aureus, Klebsiella aerogenes and Proteus vulgaris are 160 µg/mL, 100 µg/mL, 120 µg/mL for the compound 3 and 180 µg/mL, 130 µg/mL 150 µg/mL for the compound 5, respectively. In addition, compounds 1, 2, 3 and 5 was first found to have the ability to inhibit the invasion and migration of A549 cells (lung cancer cells), which exhibited the potentiality for these compounds to be used as novel anticancer drugs. This study provides a novel production strain for compounds 1, 2, 3 and 5, and four potential promising anticancer agents.
“Let’s Not Have the Perfect Be the Enemy of the Good”: Social Impact Bonds, Randomized Controlled Trials, and the Valuation of Social Programs

This article uses the case of “social impact bonds” (SIBs) to explore the role of social science methods in new markets in “social investment. ” Pioneered in the UK in 2010, SIBs use private capital to fund social programs with governments paying returns for successful outcomes. Central to the SIB model is the question of evaluation and the method to be used in determining program outcomes and investor returns. In the United States, the randomized controlled trial (RCT) has been the dominant method. However, this has not been without controversy. Some SIB practitioners and investors have argued that, while this may be the perfect tool, the need to grow the SIB market demands a more pragmatic approach. Drawing from a three-year study of SIBs, and informed by Science and Technology Studies (STS)-inspired work on valuation and the social life of methods, the article explores RCTs as both a valuation technology central to SIB design and the object of a micropolitics of valuation which has impeded market growth. It is the relationship between, and the politics of, evaluation and valuation that is a key lesson of the SIB experiment and an important insight for future research on “social investment” and other settings where methods are constitutive of financial value.
Colorectal cancer during pregnancy or postpartum: Case series and literature review

Background Colorectal cancer in young adults is on the rise. This rise combined with delayed childbearing increases the likelihood of colorectal cancer diagnosed during pregnancy or in the postpartum period. Methods Electronic health records were used to identify individuals with colorectal cancer in pregnancy or the postpartum period from 1 August 2007 to 1 August 2019. Results Forty-two cases were identified. Median age at diagnosis was 33 years. Most (93%) were diagnosed in an advanced stage (III or IV) and had left-sided colorectal cancer tumors (81%). Molecular analysis was completed in 18 (43%) women with microsatellite status available in 40 (95%). The findings were similar to historical controls. Sixty percent were diagnosed in the postpartum period. Common presenting symptoms were rectal bleeding and abdominal pain. Conclusion Currently there is no consensus recommendation regarding how to manage colorectal cancer during pregnancy. Given the overlapping symptoms with pregnancy, patients often present with advanced disease. We encourage all health care professionals caring for pregnant women to fully evaluate women with persistent gastrointestinal symptoms to rule out colorectal cancer.
Beneficial Use of Water Treatment Sludge in Geotechnical Applications as a Sustainable Alternative to Preserve Natural Soils

This paper explores the feasibility of employing drinking water treatment sludge (WTS) mixed with soils, lime, or rock powder in geotechnical applications, as well as discusses the sustainability of the approach based on experimental results, aiming at the beneficial reuse of waste and the preservation of natural geomaterials. The selected materials were two soils largely used in earthworks, two WTSs, a high purity calcium hydrated lime, and rock powder from a granitic–gneissic quarry, all occurring in São Paulo State, Brazil. The mixtures were chemically, mineralogically, and geotechnically characterized, and the geotechnical properties permeability, shear strength, and deformability were investigated. Soil-WTS mixtures showed hydraulic conductivity (10−10–10−6 m/s, depending on soil and WTS), effective cohesion (10–30 kPa), friction angle (34°–40°), undrained strength (>50 kPa), and compression index (0.1–0.4) compatible with those of soils usually employed in earthworks. Lime:WTS and rock powder:WTS mixtures achieved 50 kPa undrained strength for WTS contents lower than 24% and 8%, respectively, and could be used as daily and intermediate covers of waste landfills, as well as in other applications with low soliciting stresses. The possibility of WTS being pumped instead of transported by trucks was analyzed in the light of results from rheological tests.
Blue Light Upregulates Auxin Signaling and Stimulates Root Formation in Irregular Rooting of Rosemary Cuttings

Irregular rooting of rosemary stem cuttings, causing differences in either stem maturation or responses to growth conditions, restricts uniform production. Here, rooting efficiency of apical, middle, and basal cuttings from rosemary stems was evaluated by controlling light conditions to prevent irregular rooting. The types of light applied to the cuttings were natural sunlight (NSL), fluorescent, red, and blue (BL) light. Among these light sources, BL significantly induced root growth of not only basal cuttings, but also apical and middle cuttings, whereas NSL induced poor root formation in apical and middle cuttings. In particular, the roots of apical cuttings exposed to BL grew twice as fast as those exposed to other types of light. The overexpression of BL-induced IAA synthetic genes confirmed the rooting patterns. IAA synthetic genes were significantly upregulated by BL in the apical and middle cuttings. Irradiating with 50 μmol photons m−2 s−1 BL resulted in similar root production levels among the cutting positions with high biomass, guaranteeing the successful production of uniform cuttings. Thus, the application of proper high-intensity BL promoted healthy, similar-quality rosemary cuttings among stem cutting positions.
Digital Society Incubator: Combining Exponential Technology and Human Potential to Build Resilient Entrepreneurial Ecosystems

Although exponential technologies promise to bring unprecedented value at the socio-economic and policy levels, the social acceptability and preparedness for the technological “singularity” should be carefully considered. In particular, whereas digital innovation is able to drive an extraordinary development of entrepreneurial ventures, a number of challenging issues and the ongoing pandemic crisis have increased the need to investigate how technological breakthrough and human capital can be effectively combined in order to build resilient socio-technical and entrepreneurial ecosystems. This paper offers a synopsis of the major investigation areas and a reflection on the themes associated with the emergence of a digital society and the affirmation of digital entrepreneurship ecosystems. The research process follows a systematic literature review and a conceptual development approach aimed to introduce both the concept and a model of the digital society “incubator”. The proposed model identifies the actors, values, flows, and processes that are required to support the construction of a resilient entrepreneurial ecosystem. In this perspective, the study proposes a new focus by hybridizing and integrating both entrepreneurial and technology-related dimensions into a single unifying model. The study also lays the groundwork for further studies aimed at identifying the environmental and institutional factors required to support a smooth and effective transition towards a resilient entrepreneurial and technology-driven society.
