The purpose of this review is to summarize the available literature on the effect of vitamin and mineral supplements, especially in doses exceeding recommended daily allowances.

A comprehensive search and analysis of original, peer‐reviewed literature on supplementation studies was conducted.

High doses of vitamins and minerals can be harmful instead of beneficial. Supplementation of vitamins and minerals, in general, may be most beneficial, and perhaps only beneficial, to individuals with a nutrient‐deficient diet. Consumers thus need to be weary of the safety and efficacy of their supplements. While vitamins and minerals are vital to life, the optimal doses of each required nutrient are currently not known.

Lack of standardization between studies makes it difficult to compare the results from different studies.Practical implications – Based on this review, a recommendation can be made to avoid high dose supplements and obtain vitamins from foods to the greatest extent possible.Originality/value – This review is unique in its comprehensive nature that allows the identification of common underlying problems with the supplementation of different groups of vitamins.

Rapid technological advancements present many opportunities in the way people work, communicate and conduct business. That growth is especially prevalent in the World Wide Web. In the last five years, the Internet has expanded the market place to a global arena. More and more companies are conducting business online. Multinational corporations are becoming extremely dependent on the exchange of information across the Internet. As information flows across national borders, the concern for data security increases. Accordingly, personal data and business transactions collected by international companies are no longer safe once they enter the realm of the Internet. This paper addresses privacy concerns of e‐commerce customers, the security regulations imposed on multinational companies transferring data across international boundaries, and the risks of not complying with data protection regulations.

Workplace well-being is key to improving health and therefore productivity. Although the Chinese population and their influence on business in the UK are growing rapidly, little is known about the attitudes of Chinese employers and employees towards workplace well-being. The paper aims to discuss this issue.

The authors conducted a qualitative study to explore the views of Chinese employees and employers in London and interviewed occupational health and workplace well-being experts.

Employers’ understanding of workplace well-being was limited, their approach was reactive rather than proactive. Contextual factors hampered most efforts towards workplace well-being. Employees reported that working conditions were generally poor with likely implications for employees’ physical and mental health. Generational and migratory changes further complicate the scenario but potentially usher in positive change.

This study was conducted in a London area with a high density of Chinese businesses. The study nevertheless covered only a limited selection of business sectors. Caution may therefore be necessary in assuming the transferability of these findings to other parts of the UK.

Chinese businesses are agreeable to being informed about and considering the business case for workplace well-being. Chinese workers need better working conditions, easier access to health services preferably delivered through Chinese-based networks of community and business associations which are trusted by both employers and employees.

This study offers novel evidence on the attitude of Chinese employers and employees towards workplace well-being by comparing views from both groups. Chinese people face considerable health and mental health problems through their work environment, in contrast with conclusions from the Health Survey for England and Labour Force Survey.

The purpose of this study was to investigate pre-service teachers' concerns about including diverse learners in their classrooms. The study identified which concerns they ranked highest and lowest and which types of diversity they were most concerned about. The study also compared results in relation to demographic variables of gender, year and major.

Data collection relied on the Concerns about Inclusive Education Scale administered online with 343 pre-service teachers enrolled in higher education in Thailand. Analysis aimed to identify what were the highest categories of concerns as well as any significant relationships between concerns and demographic variables of gender, year and major. Analysis also identified the types of diversity about which pre-service teachers were most concerned along with any significant relationships between types of diversity and gender, year and major.

Results revealed that pre-service teachers ranked lack of resources as their highest concern about teaching diverse learners. Analysis revealed a significant difference for gender with females (p = 0.014) having a significantly higher level of concern about lack of resources than males. Mental health disabilities along with physical and learning disabilities were ranked highest in terms of types of diversity about which they were most concerned. There were no statistically significant differences for demographics regarding type of diversity about which teachers were most concerned.

There is a lack of research related to higher education's role in preparing teachers to teach in contexts of diversity. This study goes beyond traditional definitions to include 12 types of diversity.

Many undergraduates major in business in hopes of being well-prepared for a career. However, Arum and Roksa (2010) find business students perform poorly relative to peers on measures of academic gains and employers report that few college graduates are well-prepared for business careers (Lumina Foundation, 2013). Experiential courses have the potential to engage students deeply and encourage critical thinking while developing important business skills. The paper aims to discuss these issues.

This paper proposes several attributes of successful experiential courses and uses a student-managed portfolio as an example of a successful model.

Student-managed portfolios can improve educational and career outcomes for students.

Student-managed investment funds can provide a vehicle for teaching students research, critical thinking and writing skills while encouraging them to integrate knowledge from a broad range of business disciplines to understand a firm’s business model.

While experiential programs are touted as addressing these shortcomings, many academics remain skeptical of experiential programs which too often focus on showy trips, passively listening to important people or performing shallow analyses at the expense of developing a deep understanding of how to identify and solve complex problems. This paper offers some insight into important features of a successful experiential program.

The purpose of this paper is to argue for the development of a vibrant domestic tourism sector in emerging economies as a means of moving towards a more sustainable tourism sector and achieving many of the goals outlined in the UNWTO’s 2030 Agenda for Sustainable Development.

It uses a perspective approach through a critical state-of-the-art review of selected domestic and international tourism studies.

This paper illustrates how developing such a sector will provide a range of economic and social benefits to emerging economies and their residents, as well as lowering the per-capita tourism carbon footprint of destination areas.

This study identifies policy initiatives that can be developed to help emerging economies transition from an international tourism focus to a more balanced focus.

This study indicates the social benefits of developing a domestic tourism sector in emerging economies.

It equips national tourism organisations and small and medium tourism enterprises with specific actions for the use of tourism as a prosperity tool in the pursuance of these benefits. It, further, calls for a research agenda on investigating how emerging economies are uniquely progressing towards this global goal through thriving domestic tourism recognising that each economy is culturally different.

The health movement that has been sweeping this country has given rise to increased consumer awareness of both prescription and nonprescription medications. One of several responses to this heightened interest has been a plethora of drug information publications aimed at the general public audience. Some of these publications became so popular they attained positions on the best‐seller list. At the same time books, such as the PDR, that had generally been available only to health professionals began to find their way into popular bookstores.

The purpose of this study is to discuss the significance of “contextual factors” on the talent development of underserved populations. Understanding the “context” and background of an individual provides greater insight into their life experiences (Paik, 2013). Race, class and gender, in particular, play a role in one’s life, providing both barriers and opportunities.

To examine contextual and other factors, in-depth biographical case studies were systematically studied across 10 diverse notable artists and scientists. Over 85 autobiographies, biographies and other sources were carefully content-analyzed for commonalities and differences in artists’ and scientists’ lives.

Because of their ascribed statuses (e.g. race, class, gender), these individuals had to navigate their unique school and life circumstances. Within their sociocultural contexts, however, key relationships (e.g. parents, teachers, mentors and peers) helped mitigate the challenges. All artists and scientists had a “village” – key stakeholders who invested in them at every stage of their talent development.

Parents, teachers, mentors and peers are not only critical, but they are lifelines for talent development. Key implications discuss the role of contextual factors and support networks for aspiring diverse artists and scientists.

The theoretical framework for this study is based on the productive giftedness model (PGM) (Paik, 2013, 2015). PGM includes 10 key psychosocial and environmental factors and how they influence “productive giftedness” (e.g. achievements, accomplishments, leadership). Within the model, both “alterable” and “contextual factors” provide access to different opportunities, support and resources. The model is considered generalizable and applicable for diverse populations.

Over-tourism signifies the dilemma of managing tourism growth in cities. With growing media sensationalism and an oversimplification of the phenomenon of over-tourism, its academic theorization has become extremely important. Using Macau, a Special Administrative Region of China as a case in point, the purpose of this paper is to theoretically explore the nexus between over-tourism and sustainable consumption in cities, highlighting governments’ inevitable role in this successful convergence.

The study is based on a selective systematic literature review (SLR) of existing studies in the form of both news material and academic journals. It investigates the growing concern of over-tourism and the contribution of sustainable consumption grounded in strong political support. It also adopts a case study approach with specific reference to Macau.

The general overview of the literature provides evidence of an age-old concept that has re-emerged to make local residents’ voice more pronounced. Generally, the studies concentrate on understanding residents’ attitudes, the perceived impact of over-tourism, community resilience and sustainable strategies to tackle the problem. Most popular studies are recent (i.e. 2018 and beyond) and empirically set in developed cities of Europe.

The SLR used in the current study requires further empirical testing to validate some of the proposed concepts in the literature.

The study highlights the role of government in ensuring that sustainable consumption is sustainably implemented in the context of over-tourism.

Given the re-emergence of over-tourism, yet with few theoretical discussions on the concept, this study serves as a knowledge-base for future studies both empirically and theoretically.
