Bullying and Being Bullied; How Much Can It Increase the Risk of Depression and Anxiety in Students? A Multilevel Fixed-effect Model Analysis

Background: School violence as a health issue is a global concern. One of the problems that affect the health and well-being of children at school is bullying. Objectives: In this study, we aimed to examine the association of depression and anxiety with bullying among 6 - 19-year-old students in Iran. Methods: This study was conducted in Tehran, Iran, in 2020. A multistage cluster sampling method was used, and 54,550 students aged six to 19 years of both sexes, from urban and rural areas, were selected. Standard questionnaires, according to the WHO recommendations, were used for data collection. Involvement in bullying in the past 12 months and anxiety and depression status in both bully and bullied students were investigated by standard questionnaires. To compare the psychiatric problems and violent behavior, the Wald chi-square test was applied. The multilevel fixed-effect model and logistic multivariate regression were used to adjust the multilevel effects and estimate the odds of anxiety and depression in both bully and bullied students. All statistical analyses were performed at a 95% significance level. Results: Of the total students, 50.9% were males, 29.45% were in the 6 - 10 age group, and 70.55% in the 11 - 19 age group. There was a significant difference in depression and anxiety between boys and girls in both age groups (P < 0.001). Amongst males, 11.7% of the students aged 6 - 10 and 11% of the students aged 11 - 19 and in females, 7.7% aged 6 - 10 and 10.4% aged 11 - 19 had at least four experiences of bullying to others in the last year. The odds ratios for depression in male bullies were 1.3 and 1.5 in 6 - 10 and 11 - 19 age groups, respectively. The odds ratios for depression in bullied males and females were 4.2 and 3.9 in 6 - 10 and 2.9 and 4.3 in 11 - 19 age groups, respectively. Bulling others increased the odds of anxiety to 1.7 and 1.9 in males and 2.1 and 1.9 in females in 6 - 10 and 11 - 19 age groups, respectively. In bullied students, the odds of anxiety were estimated at 2.9 and 2.2 in males and 3.4 and 2.2 in female students respectively, in 6 - 10 and 11 - 19 age groups. Conclusions: There was a significant positive association between psychological disorders (anxiety and depression) and bullying among 6 - 19-year-old students. Victims of bullying were more at risk of depression and anxiety. This health-threatening phenomenon should not be ignored.
Making Unequal Democracy Work? The Effects of Income on Voter Turnout in Northern Italy

: In many democracies, voter turnout is higher among the rich than the poor. But do changes in income lead to changes in electoral participation? We address this question with unique administrative data matching a decade of individual tax records with voter rolls in a large municipality in northern Italy. We document several important findings. First, levels of income and turnout both dropped disproportionately among relatively poor citizens following the Great Recession. Second, we show that within-individual changes in income have an effect on participation, which is modest on average due to diminishing returns, but can be consequential among the poor. Third, we find that declining turnout of voters facing economic insecurity has exacerbated the income skew in participation, suggesting that income inequality and turnout inequality may reinforce each other. We discuss the theoretical implications of these results, set in a context with strong civic traditions and low barriers to voting. Verification Materials: The materials required to verify the computational reproducibility of the results, procedures, and analyses in this article are available on the American Journal of Political Science Dataverse within the Harvard Dataverse Network, at: https://doi.org/10.7910/DVN/IN2E8O.
Aggregate stability and organic carbon stock under different land uses integrally regulated by binding agents and chemical properties in saline‐sodic soils

Aggregate stability and soil organic carbon (SOC) are critical for maintaining soil structure and preserving soil productivity. Land use substantially affects the process of soil aggregate stabilization and SOC sequestration, yet the detailed mechanisms have not been well studied in degraded soil ecosystems (e.g., saline‐sodic soils). Therefore, to interpret the effects of land‐use changes on soil aggregate stability and SOC stocks in saline‐sodic soils, soils were sampled from four major land‐use areas (degraded meadow, artificial forest, sorghum field, and paddy field) in Northeast China. The results showed that artificial forest soils exhibited the greatest proportion of water‐stable aggregate (>250 μm) in 0–10 and 10–20 cm layers than sorghum and paddy field, which was mainly due to the absence of tillage disturbance. The highest SOC stock (59.79 Mg ha−1) was observed in paddy soils, indicating its greater SOC sequestration potential than those of other land uses. The variance partition analysis (VPA) revealed that soil parameters resulted in 85.1% variation regarding soil aggregate stability, in which the chemical characteristics (i.e., pH, EC, exchangeable Na+, and exchangeable sodium percentage) contributed 23.1%, binding agents (SOC, exchangeable Ca2+, and poorly crystalline Fe/Al oxides) contributed 20.6%, and their interactions contributed 39.5%. Binding agents directly participated in soil aggregation processes by forming clay‐polyvalent metal complexes, while the chemical characteristics indirectly promoted soil aggregation via increasing various binding agents. Understanding the interactions between binding agents and clay are important for promoting soil aggregate stabilization in saline‐sodic soil.
The utility of social practice theory in risk research

Abstract Social science risk studies often begin with one of two starting points: a particular risk, such as that of natural or technical disasters, or, alternately, with the individual experiencing risk. But risk may not be the guiding concept for how people act in the social world. This article explores how social practice theory broadens the possible starting points for social science risk research and in turn improve our understanding of risk. It does so by drawing on existing empirical studies within risk research that make use of practice-oriented theories and outline three essential arguments for practice-based risk research. First, that risk is understood as embedded in socially shared practices, second, that risk is routinised, and third, that risk is present in both social and material relations. Together, these arguments make out an analytical starting point of ‘practices of interest and intersecting practices’, representing a methodological situationalism, where actions rather than actors are at the core of research. In conclusion, a sensibility for practice in risk research is suggested.

Engaging with Labour Migrants: Emigration Policy in Tajikistan

ABSTRACT Tajikistan is one of the main migrant origin countries in the post-Soviet world, with about one million labour migrants living and working in Russia. It is also one of the world’s most remittance-dependent economies. By exploring how and why the Tajik government has engaged with labour migrants since 1991, this article analyses the development of emigration policy in Tajikistan. In doing so, the article de-reifies the state and illustrates the complexity of policy processes: many actors are directly and indirectly involved in policymaking and implementation. Four aspects are analysed: shifts in emigration policymaking over time and the influence of different domestic actors; the assistance offered to labour migrants; the impact of Russia as the main host country; and the influence of international organisations in the context of the nascent global governance of migration. This article argues that Tajikistan’s emigration policy has gradually moved from a laissez-faire phase, through a proactive, then a “messy”, to a reactive one. It shows that Tajik authorities have followed often contradictory pathways of (non)involvement with labour migrants and thereby illustrates how declared policies can be distinguished from informal practices performed by the state.
Decentralization for Increased Sustainability in Natural Resource Management? Two Cautionary Cases from Ghana

In Sub-Saharan African countries, governments are increasingly devolving natural resource management from central administration to the local government level as a trend toward subsidiarity. In parallel, efforts to implement formalization processes have resulted in a puzzling institutional arena, wherein mixed actors are struggling to influence the paths of institutional change and the associated distribution of land and land-related resources. Relying on political ecology and new institutionalism in social anthropology, we investigate how the decentralization of formalization of rights in artisanal and small-scale gold mining can lead to paradoxical outcomes, often negatively impacting social, economic, and environmental sustainability. Two comparative case studies are performed in Ghana. Our results show that the negative effects of formalization efforts for resource end users are to be understood in the broad context of actors’ repositioning strategies following the selective implementation of decentralization. The authors conclude that increasing the power of the central government and line ministries to control local resources can influence the disenfranchisement of local people’s participation and control of natural resources, resulting in a relentless environmental crisis.
1H and 13C NMR for the Profiling of Natural Product Extracts: Theory and Applications

Nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS) are the principal methods of metabolomics, the branch of ‘-omics’ that deals with small molecules. Although MS is gaining popularity in metabolomics, NMR enjoys a number of key advantages because it is nondestructive, unbiased, quantitative, does not require separation or derivatization, and is amenable to compounds that are difficult to analyze by gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS). There are two general approaches to the use of NMR for profiling studies: an untargeted approach, which uses chemometric analysis; and a targeted approach, which aims to quantify known compounds in the extract. These approaches, however, are not mutually exclusive and will likely converge in the future. This paper will describe the basic theoretical principles that should be considered to develop NMR into a standard quantitative method. Although 1H NMR is more sensitive, 13C NMR spectra are simpler with less overlapping signals and are less affected by different magnetic field strengths. Various applications of 1H and 13C NMR for the profiling of natural products are described. The use of two-dimensional 1H NMR has been used to overcome problems of spectral overlap. The standardization of the NMR protocol will make it a more useful tool for the profiling of natural products extracts.
Catch me if you can: personality drives technique-specific biases during live-capture trapping

Abstract Context. Wildlife surveys often rely on a single live-capture technique to sample animal populations. Yet, animal personality (e.g. bold vs shy) can drive heterogeneity in capture probability, leading to biased sampling during live-capture trapping surveys. Aims. We tested whether a personality-related capture bias is similar between two live-capture techniques, or whether techniques with different capture mechanisms are biased towards certain spectrums of personality. Methods. We compared two live-capture techniques commonly used for surveying lizards, namely, noosing and pitfall traps. Techniques were deployed several days apart to survey populations of a desert-dwelling agamid, the military dragon, and we used outdoor open-field arenas to test for personality traits relating to boldness, activity and exploration. Key results. We found that noosing and pitfall traps sampled distinctly different spectrums of personality, with no individuals being captured by both techniques. Unexpectedly, noosing, which involved people approaching dragons to capture them, was biased towards shyer individuals that stayed close to shelter. In contrast, pitfall traps, which were generally set in open areas, were biased towards capturing individuals that moved further from shelter. Conclusions. We demonstrated that different live-capture techniques can be biased towards different spectrums of personality. We attribute the relationship between personality and technique to an interaction between the capture mechanisms of each technique and individual perceptions of risk and microhabitat use. Implications. To overcome biased and selective sampling and target individuals along a broad spectrum of personality, surveys should use complementary techniques that vary in their capture mechanisms.
Topic choices: Revealing concealed processes of curriculum sequencing in English secondary school Music classrooms

Music curriculum programmes are designed by English Music teachers in schools as the primary means of musical engagement for young people aged 11– 14. Such Music curricula are often structured in learning topics. However, Music teacher rationales for the sequencing of the topics they have chosen to include in their curriculum is an under- developed area of music education research literature. This study seeks to examine teacher practices in this domain through a comparative case study of nine English secondary school teachers using Think Aloud Protocols to uncover sequencing practices. The findings are analysed using the Friedman ANOVA statistical test and eyeball analysis of teacher curriculum formulations. Theorising from these results facilitated the development of a teacher model of curriculum processing, and illuminated hidden practices in curriculum design.
Bio-Catalytic Activity of Novel Mentha arvensis Intervened Biocompatible Magnesium Oxide Nanomaterials

In the present study Mentha arvensis medaited Magnesium oxide nanoparticles were synthesized by novel green route followed by advanced characterization via XRD, FTIR, UV, SEM, TEM, DLS and TGA. The mean grain size of 32.4 nm and crystallite fcc morphology were confirmed by X-ray diffractive analysis. Scanning and Transmission electron microscopy analysis revealed the spherical and elliptical morphologies of the biosynthesized nanoparticles. Particle surface charge of −16.1 mV were determined by zeta potential and zeta size of 30–120 nm via dynamic light scattering method. Fourier transform spectroscopic analysis revealed the possible involvement of functional groups in the plant extract in reduction of Mg2+ ions to Mg0. Furthermore, the antioxidant, anti-Alzheimer, anti-cancer, and anti-H. pylori activities were performed. The results revealed that MgO-NPs has significant anti-H. pyloric potential by giving ZOI of 17.19 ± 0.83 mm against Helicobacter felis followed by Helicobacter suis. MgO-NPs inhibited protein kinase enzyme up to 12.44 ± 0.72% at 5 mg/mL and thus showed eminent anticancer activity. Significant free radicals scavenging and hemocompatability was also shown by MgO-NPs. MgO-NPs also displayed good inhibition potential against Hela cell lines with maximum inhibition of 49.49 ± 1.18 at 400 µg/mL. Owing to ecofriendly synthesis, non-toxic and biocompatible nature, Mentha arvensis synthesized MgO-NPs can be used as potent antimicrobial agent in therapeutic applications.
Advances in understanding of mycorrhizal-like associations in bryophytes

Mutually beneficial associations between plants and soil fungi, mycorrhizas, are one of the most important terrestrial symbioses. These partnerships are thought to have propelled plant terrestrialisation some 500 million years ago and today they play major roles in ecosystem functioning. It has long been known that bryophytes harbour, in their living tissues, fungal symbionts, recently identified as belonging to the three mycorrhizal fungal lineages Glomeromycotina, Ascomycota and Basidiomycota. Latest advances in understanding of fungal associations in bryophytes have been largely driven by the discovery, nearly a decade ago, that early divergent liverwort clades, including the most basal Haplomitriopsida, and some hornworts, engage with a wider repertoire of fungal symbionts than previously thought, including endogonaceous members of the ancient sub-phylum Mucoromycotina. Subsequent global molecular and cytological studies have revealed that Mucoromycotina symbionts, alongside Glomeromycotina, are widespread in both complex and simple thalloid liverworts and throughout hornworts, with physiological studies confirming that, in liverworts at least, these associations are mycorrhizal-like, and highlighting important functional differences between Mucoromycotina and Glomeromycotina symbioses. Whether a more prominent role of Mucoromycotina symbionts in plant nitrogen nutrition, as identified in liverworts, extends to other plant lineages, including the flowering plants, is a major topic for future research. The latest finding that ascomycete symbionts of leafy liverworts are not restricted to one fungus, Rhizoscyphus ericae, but include species in the genus Meliniomyces, as shown here in Mylia anomala, together with the recent demonstration that R. ericae forms nutritional mutualisms with the rhizoids of Cephalozia bicuspidata, fill other major gaps in our growing knowledge of fungal associations across land plants.
Role Reversal! Financial Performance as an Antecedent of ESG: The Moderating Effect of Total Quality Management

Shifting from short-term profit maximizing strategies to more sustainable long-term ones, the corporate world has been exerting extra effort to adopt environmental, social, and governance (ESG) performances. However, the loop question remains unsolved: is ESG financially-driven or is financial performance (FIN) ESG-driven? Building on the slack resources theory and bridging three management literatures, this analysis relies on a six-year panel dataset of multinational organizations from different industries. A distributed lag regression model is proposed to empirically investigate the impact of FIN performance on ESG and to test the moderator effect of total quality management (TQM). The findings reveal a stimulus effect between free cash flow (FCF) and ESG scores. While the interaction between TQM and FCF has a negative effect on ESG, the interaction between TQM and Tobin’s Q reveals a positive relationship with ESG. This study sheds further insights for both research and practice towards the operationalization of sustainability management.
The History and Driving Force for Prehistoric Human Expansion Upward to the Hinterland of the Tibetan Plateau Post–Last Glacial Maximum

The timing and motivation of prehistoric human expansion into the hinterland of the Tibetan Plateau (TP) is a widely debated scientific issue. Recent archaeological studies have brought forward predictions of the earliest human occupation of the TP to the late–Middle Pleistocene. However, massive human occupation of the TP did not appear until the termination of the Last Glacial Maximum (LGM). The spatio-temporal distribution of prehistoric hunter-gatherers on the TP varies significantly before the permanent occupation after 3600 BP (before present). Here, we report on environmental-archaeological evidence from the Canxionggashuo (CXGS) site in Yushu Prefecture, which provides information that is key to understanding the dynamics of post-LGM human occupation on the TP. Radiocarbon dating has revealed two occupation periods of the CXGS site at 8600–7100 cal (calibrated years) BP and 2400–2100 cal BP. The charcoal concentration in cultural layers correlates well with paleo–human activities. Hunter-gatherers expanded westwards from the northeastern margin of the TP to the hinterland of the TP during the warming period of the early–middle Holocene (~11,500–6000 BP). However, these groups retreated during the middle–late Holocene (~6000–3600 BP) under a cooling-drying climate. Prehistoric humans finally occupied the hinterland of the TP permanently after 3600 BP, with an enhanced cold-adaptive lifestyle, although the climate was still deteriorating.
Goodness-of-fit testing based on Gini Index of spacings for progressively Type-II censored data

Abstract In this article, we propose two new scale invariant test statistics when the available data are subject to progressively Type-II censoring. The proposed tests are based on Gini index of spacings. It is observed thorough extensive Monte Carlo simulations that the proposed tests are quite powerful in compare to similar existing goodness-of-fit tests studied by Balakrishnan et al. and Wang. We also illustrate the method proposed here using a real data from reliability literature.
Perceived Importance of Core Competencies among Extension Professionals in Nepal

Agricultural systems are evolving globally. Farmers and agri-entrepreneurs are demanding trustworthy and efficient extension and advisory services that they can rely on to improve their farming systems and associated enterprises. In this context, extension professionals are expected to be versatile and be competent in their services. Competency refers to having required knowledge, skills and abilities in both process skills and technical subject matters to effectively deliver assigned services. Competency needs are context specific and dynamic. Thus, it is imperative to periodically examine what competencies extension professionals possess and how they value them. This cross-sectional study sought to examine the perceived importance of key competencies among agricultural extension professionals in Nepal. Extension professionals in Nepal’s public agricultural and livestock development offices and agriculture-based non-governmental organizations comprised the study population. Survey data were collected from August to September 2015 through self-, group-administered, and web-based questionnaire. The respondents rated eight core competencies as important or very important. Their perceptions of the importance of these core competencies significantly differed across their current positions, level of education, age, and experience in extension services but not across their educational institutions, employers, and gender. There is a need to develop extension education curricula integrating these core competencies and providing education and training on these core competencies to extension professionals.
