Background: The prevalence of obesity in English adults and children has reached critical levels. Obesity is determined by a wide range of factors including the environment and actions to reduce obesity prevalence requires a whole systems approach. The spatial planning system empowers local authorities to manage land use and development decisions to tackle obesogenic environments.

Methods: This research aimed to better understand what and how planning powers are being utilised by local authorities to help tackle population obesity. It reviewed literature on the six planning healthy weight environments themes. It identified what powers exist within the planning system to address these themes. It collated professionals’ perspectives on the barriers and opportunities through focus groups within local authorities and semi-structured interviews with national stakeholders.

Results: The research complements current research on the association between the environment and obesity outcomes, though methods employed by researchers in the literature were inconsistent. It identified three categories of planning powers available to both require and encourage those with responsibilities for and involvement in planning healthy weight environments. Through direct engagement with practitioners, it highlighted challenges in promoting healthy weight environments, including wider systems barriers such as conflicting policy priorities, lack of policy prescription and alignment at local levels, and impact from reduced professional and institutional capacity in local government.

Conclusions: The conclusions support a small but increasing body of research which suggests that policy makers need to ensure barriers are removed before planning powers can be effectively used to promote healthy weight environments as part of a whole systems approach. The research is timely with continuing policy and guidance focus on tackling obesity prevalence from national government departments and their agencies. This research was conducted as part of a Master of Research at Leeds Beckett University associated with a national whole-systems to obesity programme.

The purpose of this paper is to understand demographic group (race, first-generation college graduate, gender, age) differences among perceived family and faculty social and family financial support within the US graduate school admissions pipeline in the social sciences.

Using data from a cross-sectional convenience sample survey (N = 99), this paper looks at ordinal social support variables (faculty member support, family social support and family financial support) by demographic groups. This paper uses a Mann–Whitney U test to compare first-generation status, race and gender and a Kruskal–Wallis H test to compare age groups.

This paper finds that applicants over 27 years old had significantly less faculty support in the graduate admissions pipeline compared to other age groups; differences in faculty support across race were marginally significant (p = 0.057). Regarding family social support, this paper finds first-generation applicants, male applicants and applicants over 27 years old report lower levels of support. Finally, this paper finds first-generation applicants and applicants over 27 years old report lower levels of familial financial support.

Previous literature on graduate admissions – published in this journal (Pieper and Krsmanovic, 2022) and others – does not consider experiences up to and before applicants hit the “submit” button on graduate applicants, which the authors term the graduate admissions pipeline. Instead, most previous literatures focus on faculty committees and validity of required application materials. Thus, this study begins to answer Posselt and Grodsky’s (2017) call to develop an understanding of applicant experiences and support within the graduate admissions pipeline.

Much prior work involving director incentives and corporate behaviour has been focussing on their absolute dollar value or the intrinsic value and generated mixed findings. Comparison theories, however, suggest that the relative value of an incentive may be the main drive for individual performance. This study attempts to investigate the role of director relative pay in promoting the board’s intervention with unrelated diversification decisions.

The analysis uses data from firms operating in more than one segment during the period from 1999 to 2019. Data were obtained from WRDS databases. Ordinary least squares (OLS) regression analysis and the two-stage system generalized method of moments (GMM) were run to test the hypotheses. To test the robustness of the findings, alternative proxies for the key independent variables were used in separate analyses.

The results support the hypothesis that unrelated diversification negatively impact firm performance, while higher director relative pay will help reduce unrelated business diversification. The absolute director pay, however, has no significant impact on corporate strategic choices. The results also highlight the moderating effect of director overcompensation. Director overcompensation will cancel out the impact of relative director pay on unrelated diversification.

This study takes a fresh theoretical perspective by framing the investigation using the dimensional comparison theory to address the single untended comparison framework in the director pay structure – the intra-individual framework. It is the first to investigate the role of director relative pay in corporate strategic choices. The findings support the contention that the relative value of the incentive is an important indicator of the effectiveness of the pay.

Turnover in high-tech companies has long been a concern for managers and executives. Recent meta-analyses from the general turnover literature consistently show that job satisfaction is a major attitudinal antecedent to turnover intention and turnover behavior. Additionally, the available research on information technology (IT) employees focuses primarily on turnover intentions and not on a risky decision-making perspective and actual turnover (turnover behavior). The paper aim is to focus on that.

This study uses hierarchical ordinary least squares, process (Preacher and Hayes, 2004) and logistic regression.

The main predictor of actual turnover is risky decision-making, whereas job satisfaction is the main predictor of turnover intention.

The joint effects of risk and job satisfaction on turnover intention and behavior have not been studied in the IT domain. Hence, this study extends our understanding of turnover in general and particularly among IT employees by studying the combined effect of risk and job satisfaction on turnover intentions and turnover behavior. The study’s theoretical and practical implications are likewise discussed.

The effects of board composition on performance have long been discussed in management research using fractionalization measures. In this study, we propose an alternative measurement approach based on board polarization.

Using an exploratory analysis and applying the polarization measure to German Deutscher Aktienindex (DAX)-, Midcap-DAX (MDAX)- and Small Cap-Index (SDAX)-listed companies, this paper applies the polarization index to examine the relationship between board diversity and performance.

The results show that the polarization concept is well suited to measure principal-agent problems between the members of the management and supervisory boards. We reveal that board polarization is negatively associated with firm performance, as measured by return on investment (ROI).

This exploratory study shows that the measurement of board polarization can be linked to performance differences between companies, which offers promising starting points for further research.

Illicit drug use is a well-known global problem that has been noticed to be increased significantly among medical students. This study aims to assess the prevalence and consequences of illicit drug use among medical students in the country of Jordan using the validated Drug Abuse Screening Test-10 (DAST-10).

The authors used a cross-sectional, descriptive design to conduct this study. A total of 2,104 participants from six medical schools were included. A structured online-based English self-administered questionnaire was used for data collection.

Out of 2,104 included participants, 242 (11.5%) reported using illicit drugs in the past year. More than three-quarters (77%) of the drug users suffer from various degrees of problems related to drug use, ranging from risky (41%) to severe risk (6%). Drug use was found to be associated with gender, planned specialty and exposure to psychiatry training.

The cross-sectional design prevents from drawing cause-and-effect relationships and confirming how the tendency toward substance use is affected by the psychological state, sleep quality and exposure to psychiatry. Also, although it is important to measure the subjective observation of distress and sleep, objective estimates of psychological distress and sleep including actigraphy and sleep diary could be helpful to strengthen the findings. Also using an online survey with convenience sampling are some inevitable limitations with the present COVID-19 restrictions. Also, the nature of DAST-10 closed-ended questions precluded from accurately exploring the consequences of substance abuse.

Appropriate screening to identify medical students at risk for substance abuse and provide them with treatment referrals are strongly recommended in this study. In addition, medical schools should provide a comfortable environment that encourages a healthy lifestyle with a responsible attitude toward using drugs.

There is a dearth of information about illicit drug use among medical students, especially in the country of Jordan. The nature of their studies, the different stresses they experience and the impact imposed by other factors such as sociocultural all are likely to make medical students more susceptible to drug abuse. To the best of the authors’ knowledge, this is the first cross-national study of its kind in Jordan with a representative sample of 2,104 participants. We assessed the prevalence and consequences of self-reported illicit drug use and the sleep quality of medical students from all schools of medicine in Jordan.

This study aims to follow a rigorous approach to identify, critically analyze and synthesize 75 papers published from 2000 to 2022.

The study presents a systematic literature review on identity expressiveness (IE), clarifying and expanding what is currently known about the concept.

To synthesize current knowledge on IE, the study uses the overarching framework of antecedents-phenomenon-consequences, using this same framework to identify gaps and future research directions. The findings show individual and brand-related factors such as the need for uniqueness and anthropomorphism as antecedents of IE, and eWOM/WOM, impulse purchases and upgrading to more exclusive lines as consequences of IE.

The study contributes to theory by synthesizing and mapping current understanding of the state of knowledge on the concept of IE while highlighting gaps in the extant literature and paving future research directions for scholars in the field.

The study offers useful insights for practitioners, broadening marketers’ actionable options in identity-based marketing. Marketers can use insights from this study to inform marketing strategy and communication campaigns for different types of brands.

To the best of the authors’ knowledge, this study is the first of its kind and offers an integrative review of the current literature on IE, thus enhancing understanding of the concept, its antecedents and consequences. The study also contributes to knowledge by highlighting future research priorities for researchers in this field of enquiry.

This study aims to investigate the effects of mineral rents, conflict and population growth on countries' growth, with a specific interest in 13 selected economies in Sub-Saharan Africa.

This paper uses a combination of research methods: the pooled ordinary least squares (OLS), the fixed effect and the system generalized method of moment (GMM). The consistent estimator (system GMM), which provides the paper's empirical findings, remedies the inherent endogeneity bias in the model formulation. The utilized panel dataset for the study spans from 1980 to 2022.

The study suggests that mineral rents positively affect countries' growth by about 0.407 percentage points in the short run. The study further demonstrates the long-run negative impacts of population growth rates and prevalence of civil war on economic growth. The empirical work of the study reveals that an increase in the number of international borders within the group promotes mineral conflicts, which impedes economic growth. Evidence from the specification tests performed in the study confirmed the validity of the empirical results.

Mineral rents, if well managed and conditioned on good institutions, are a blessing to an economy, contrary to the assumptions that mineral resources are a curse. The utilization of mineral rents in Sub-Saharan Africa for economic growth depends on several factors, notably the level of mineral conflicts, population growth rates, institutional factors and the ability to contain civil war, among others.

This study is the first attempt in the post-coronavirus disease 2019 (COVID-19) era to revisit the investigation of the impacts of mineral rents, conflict and population growth rates on the countries' growth while controlling for the potential implications of the qualities of institutions. One of the significant contributions of the study is the identification of high population growth rates as one of the primary drivers of mineral conflicts that impede economic growth in the states with enormous mineral deposits in Sub-Saharan Africa. The crucial inference drawn from the study is that mineral rents positively impact countries' growth, even with inherent institutional challenges, although the results could be better with good institutions.

Social media have become the main channel of direct communication between members of parliament and constituents. The study analyzes the content in all Israeli MPs' Facebook channels throughout an entire term of parliament and asks if the results are consistent with the equalization or the normalization hypotheses.

The study uses automatic analysis to produce a birds-eye-view of the content uploaded to the Facebook pages of all Israeli MPs during a full term of parliament. All 106 MP pages were automatically scraped. Some complementary information was added to each post in the dataset, such as post length (number of words) and whether the page belongs to a member of the opposition or coalition. The total of 441,974 posts was analyzed to compare engagement and publication rates between pages, coalition vs opposition MPs, MPs vs users etc.

The findings demonstrate that the MP-Facebook sphere is non-egalitarian, in that it follows skewed distributions by MPs in terms of post publication and engagement rates; non-inclusive, in that pages of coalition members receive significantly much more engagement vis-a-vis pages of members of the oppositions; and “top-down”, in that MP-authored posts receive dramatically more engagement then user-authored posts, suggesting MPs have a near-monopoly on setting the agendas manifest in their pages, while users have extremely limited agenda-setting capabilities in these pages.

Previous studies have looked at the character of the interactions between MPs and constituents on the Internet and particularly on online social media. Yet, to the best of the authors’ knowledge, no study provides a birds-eye-view of the content in all MPs' Facebook channels throughout a full term of parliament. Such an analysis provides a more comprehensive understanding of the character and dynamics of conversations that take place in such arenas.

Agricultural and food systems in the Mekong Region are undergoing transformations because of increasing engagement in international trade, alongside economic growth, dietary change and urbanisation. Food systems approaches are often used to understand these kinds of transformation processes, with particular strengths in linking social, economic and environmental dimensions of food at multiple scales. We argue that while the food systems approach strives to provide a comprehensive understanding of food production, consumption and environmental drivers, it is less well equipped to shed light on the role of actors, knowledge and power in transformation processes and on the divergent impacts and outcomes of these processes for different actors. We suggest that an approach that uses food systems as heuristics but complements it with attention to actors, knowledge and power improves our understanding of transformations such as those underway in the Mekong Region. The key transformations in the region include the emergence of regional food markets and vertically integrated supply chains that control increasing share of the market, increase in contract farming particularly in the peripheries of the region, replacement of crops cultivated for human consumption with corn grown for animal feed. These transformations are increasingly marginalising small-scale farmers, while at the same time, many other farmers increasingly pursue non-agricultural livelihoods. Food consumption is also changing, with integrated supply chains controlling substantial part of the mass market. Our analysis highlights that theoretical innovations grounded in political economy, agrarian change, development studies and rural livelihoods can help to increase theoretical depth of inquiries to accommodate the increasingly global dimensions of food. As a result, we map out a future research agenda to unpack the dynamic food system interactions and to unveil the social, economic and environmental impacts of these rapid transformations. We identify policy and managerial implications coupled with sustainable pathways for change.
