The purpose of this study is to investigate the effect of supervisor bottom-line mentality on subordinates’ frustration and subsequent attitudes (turnover intention, affective commitment and job satisfaction) and the moderating role of coworker support.

The proposed model was tested using a sample of 194 full-time working executive MBA students in the United States of America through a two-time point-paired survey.

The moderated-mediation using PLS-SEM indicated that supervisor bottom-line mentality is positively associated with subordinate frustration, which in turn increases turnover intention and reduces affective commitment and job satisfaction. Taking a competing hypotheses approach for the moderating role of coworker support, findings indicated that coworker support exacerbated (i.e. worsened) the positive relationship between supervisor bottom-line mentality and subordinate frustration.

Managers should pay close attention to the potential negative consequences of supervisor bottom-line mentality, especially in a culture where coworker support is nurtured and valued. That is, coworker support can worsen employee frustration caused by supervisor bottom-line mentality.

This study is among the first to examine how employee frustration mediates the dysfunctional relationship between supervisor bottom-line mentality and the employee attitudes of turnover, affective commitment and job satisfaction. In addition, this study illuminates a potential darkside of coworker support as it can intensify the relationship between supervisor bottom-line mentality and employee frustration, thus enriching the literature in both bottom-line mentality and social support.

Due to white rice’s association with diabetes and other chronic diseases in many Asian countries, many industries are working to develop high-fiber rice substitutes with similar organoleptic characteristics. Konjac rice (KR) is a promising option, but maintaining its optimal fiber content for health benefits while preserving its ideal sensory profile remains a challenge. This study aims to investigate whether a KR formula, combining tapioca flour and glucomannan gel, possesses similar organoleptic attributes to white rice while preventing glycemic response elevation.

In a six-week randomized single-blind clinical trial, 13 normoweight nondiabetic subjects received varying konjac-based rice and white rice ratios. Blood glucose levels were measured at intervals, and glycemic response was assessed using incremental area under the curve (iAUC). Visual analog scale gauged satiety, and organoleptic properties were evaluated.

Substituting white rice with pure and partial konjac-based rice significantly lowered postprandial blood sugar levels and glycemic response (p = 0.002). iAUC for pure KR and KR 1:1 was notably lower than white rice (p = 0.002). Subjects reported a sense of fullness comparable to white rice, with no significant organoleptic score differences (p = 0.260).

The study’s generalizability is compromised due to the limited number of participants, impacting external validity. The examined parameters offer a rough understanding of konjac grain’s impact on postprandial glycemic responses but do not elucidate underlying mechanisms or the duration of its inhibitory effect on glucose absorption. Long-term effects on metabolic, hormonal parameters and the colon’s microbial flora composition and function remain unexplored, constraining comprehensive insights into konjac grain’s extended implications.

This study introduces a novel KR formula to address the escalating diabetes risks associated with white rice consumption. Substituting white rice with KR significantly reduces postprandial blood sugar levels, highlighting its potential in preventing type 2 diabetes (T2D). Tapioca flour enhances palatability, making KR a viable option. While promising, long-term effectiveness and safety require further research, emphasizing comprehensive lifestyle interventions. The study contributes valuable insights to innovative dietary strategies for prevalent health conditions, emphasizing the need for ongoing efforts in public health.

White rice, a staple in Asian societies, is linked to a heightened risk of T2D due to increased production and inadequate dietary fiber. This connection contributes to the economic burden on governments through health insurance and lost productivity. Encouraging alternatives rich in fiber can mitigate this burden, offering a socioeconomically beneficial solution to preventable chronic diseases.

This trial demonstrates konjac-based rice’s potential in curbing glycemic responses, hinting at its role in preventing T2D. Glucomannan’s viscosity, satiety induction and potential gut health impact are highlighted. Further research is warranted for long-term effectiveness and safety. These findings contribute to the growing evidence supporting glucomannan as a valuable tool in addressing prevalent health conditions.

This study uses a comprehensive literature review and analysis of recent research, policy documents and program evaluations related to Supplemental Nutrition Assistance Program Education (SNAP-Ed) and policy, systems and environmental (PSE) strategies. Key sources include peer-reviewed articles, the 2025 SNAP-Ed Plan Guidance and case studies of successful PSE interventions. The Social-Ecological Model serves as a framework to organize and analyze the multilevel impacts of PSE interventions. The method involves identifying relevant information, synthesizing key themes and patterns and critically examining the potential impact of PSE strategies on nutrition security and health equity.

This paper examines the evolution of the SNAP-Ed from direct nutrition education to a comprehensive approach integrating PSE change strategies. It aims to analyze the rationale, implementation and potential impact of PSE approaches in SNAP-Ed on nutrition security and health equity in the USA. The study explores how these strategies address social determinants of health, promote sustainable population-level changes in nutrition environments, and their capacity to reduce health disparities in low-income communities. It seeks to identify challenges, opportunities and future research directions in implementing PSE strategies within SNAP-Ed.

The review reveals that PSE strategies in SNAP-Ed show promise in creating sustainable, population-level changes in nutrition environments and health outcomes. Successful examples, such as healthy corner store initiatives and workplace wellness programs, demonstrate the potential of PSE approaches to improve access to healthy food options and physical activity opportunities. The integration of PSE strategies has enhanced SNAP-Ed’s capacity to address social determinants of health and promote health equity. However, challenges including resource constraints, political opposition and the need for cross-sector collaboration persist. The effectiveness of PSE interventions relies heavily on community engagement, partnerships and supportive policies.

The findings underscore the importance of adopting comprehensive, multilevel approaches in nutrition education and obesity prevention programs. For SNAP-Ed implementers, this implies a need to develop expertise in PSE strategies, foster cross-sector partnerships and engage communities in intervention design and implementation. Policymakers should consider increasing support and resources for PSE approaches within SNAP-Ed and similar programs. Public health practitioners can use these insights to design more effective, equitable interventions that address root causes of nutrition insecurity. The study also highlights the need for improved evaluation methods to assess the long-term impact of PSE strategies on population health outcomes.

This study highlights the importance of addressing social determinants of health, such as poverty and access to healthy food options, to promote equitable health outcomes. It underscores the potential of community-driven, multilevel interventions in building a more just and equitable food system accessible to all.

This paper provides a comprehensive analysis of the shift toward PSE strategies in SNAP-Ed, offering valuable insights into the program’s evolution and its potential to address complex public health challenges. By examining both successes and challenges, it contributes to the growing body of evidence on the effectiveness of multilevel interventions in promoting nutrition security and health equity. The study’s emphasis on the role of community engagement and partnerships in PSE implementation offers practical guidance for program planners and policymakers.

Female entrepreneurs in tourism are increasingly asserting themselves, yet there is a need to examine the psychological empowerment dimensions of their entrepreneurial journeys. This study aims to address this gap by defining psychological empowerment typologies of female entrepreneurs operating in challenging socio-economic contexts in urban Zimbabwe.

This research used data from face-to-face and online interviews with 20 female entrepreneurs in urban Zimbabwe.

The study identified four distinct typologies of psychologically empowered entrepreneurs: resilient, collaborative, social change and authentic entrepreneurs. These typologies show unique patterns of intrapersonal, interactional, behavioural and relational empowerment dimensions, highlighting the multidimensional nature of psychological empowerment among female entrepreneurs.

This research makes an original contribution by exploring psychological empowerment typologies among female entrepreneurs in Zimbabwe. It examines the intersection of socio-economic challenges and empowerment dynamics and identifies distinct typologies. These insights provide valuable guidance for policymakers, support organisations and female entrepreneurs to design targeted interventions that enhance entrepreneurial empowerment and promote gender equality.

The purpose of this study is to extend the Fraud Diamond Theory to celebrity Special Purpose Acquisition Companies (SPACs) and investigate their post-Initial Public Offering (IPO) stock market performance.

After obtaining a sample of celebrity SPACs from the Spacresearch.com database, fraud risk characteristics were obtained from Lexis Nexus searches. Buy and hold abnormal returns were calculated for celebrity SPACs versus a small-cap equity benchmark for time intervals after IPO, and multiple regression analysis was performed to examine the relationship between fraud risk features and post-IPO returns.

Celebrity SPACs exhibit Fraud Diamond characteristics and significantly underperform a small-cap stock portfolio on a risk-adjusted basis after IPO.

This study only examines celebrity SPACs that conducted IPOs on the NYSE and NASDAQ/AMEX and does not include those that are traded on the Over the Counter Bulletin Board (OTCBB).

Celebrity endorsement of SPAC vehicles attracts investors who may not be properly informed regarding the risk characteristics of SPACs. Accordingly, investors should be warned that celebrity SPACs underperform a small-cap equity portfolio and exhibit significant elements of fraud risk.

The use of celebrity endorsement as a marketing device to attract investment in SPACs has regulatory implications.

To the best of the authors’ knowledge, this paper is the first to examine the fraud risk characteristics and post-IPO performance of celebrity SPACs.
