Over the past two decades, there has been an increased focus on designing STEM learning experiences for primary and second-level students. We posit that for teachers to design rich learning experiences for their students, they must first have the opportunity to develop their own STEM knowledge and competences, either during their pre-service teacher education or as part of their professional learning as in-service teachers. This systematic review of literature examines programmes which offer either pre-service or in-service teachers immersive learning experiences through placements in STEM roles in business or industry. A total of nine papers were identified in this review, featuring three unique programmes--one in the UK for pre-service teachers, and two in the USA involving in-service teachers. The findings indicate a variation in motivation and structures across the three programmes. The influence on teachers' personal and professional development, and their intentions to change their classroom practices or behaviours to incorporate more 'real-world' contexts into their STEM learning activities, inspired by their experiences in industry, is discussed. This study presents recommendations for the design and implementation of immersive learning placements in industry to support STEM teacher professional learning, as well as suggestions for further studies to examine the influence on their classroom practice.

Purpose: The purpose of this paper is to provide a systematic review of the current state of physician leadership. Theory of expert leadership (TEL) was applied to explore the effects of physician inherent knowledge, industry experience and leadership capabilities on leader behaviors and outcomes. Design/methodology/approach: This review (August 2011–February 2022) applied the preferred reporting items for systematic review and meta-analysis strategy. Our search began with 3,537 studies and a final sample of 12 articles. Findings: The findings offer a number of studies that note the relationship between physician leadership and the three dimensions of TEL. How influential these are on leadership behaviors and health-related outcomes varies. We also found a number of studies that described general physician leadership behaviors that were not directly linked to factors of TEL, as well as two additional themes: leader identity and trust. Originality/value: To the best of the authors' knowledge, this is the first systematic review that has applied a highly cited theory (i.e. TEL) to the data and the first that has focused solely on a U.S. population. These findings offer healthcare organizations insight into the potential strengths and challenges of physician leadership. [ABSTRACT FROM AUTHOR]

Purpose: This paper aims to investigate the association of COVID-19 confirmed cases and deaths with mental health, unemployment and financial markets-related search terms for the USA, the UK, India and worldwide using Google Trends. Design/methodology/approach: The authors use Spearman's rank correlation coefficients to assess the relationship between relative search volumes (RSVs) and mental health, unemployment and financial markets-related search terms, with the total confirmed COVID-19 cases as well as deaths in the USA, UK, India and worldwide. The sample period starts from the day 100 cases were reported for the first time, which is 7 March 2020, 13 March 2020, 23 March 2020 and 28 January 2020 for the US, the UK, India and worldwide, respectively, and ends on 25 June 2020. Findings: The results indicate a significant increase in anxiety, depression and stress leading to sleeping disorders or insomnia, further deteriorating mental health. The RSVs of employment are negatively significant, implying that people are hesitant to search for new jobs due to being susceptible to exposure, imposed lockdown and social distancing measures and changing employment patterns. The RSVs for financial terms exhibit the varying associations of COVID-19 cases and deaths with the stock market, loans, rent, etc. Research limitations/implications: This study has implications for the policymakers, health experts and the government. The state governments must provide proper medical facilities and holistic care to the affected population. It may be noted that the findings of this study only lead us to conclude about the relationship between COVID-19 cases and deaths and Google Trends searches, and do not as such indicate the effect on actual behaviour. Originality/value: To the best of the authors' knowledge, this is the first attempt to investigate the relationship between the number of COVID-19 cases and deaths in the USA, UK and India and at the global level and RSVs for mental health-related, job-related and financial keywords.

In today's highly competitive world market, businesses can hardly maintain their competitiveness without strong innovation abilities. In the past, many Chinese enterprises have enjoyed success through imitation. But to continue to succeed in a global marketplace, they must develop ambidextrous innovation abilities. The resource‐based theory eloquently posits that competitive advantage is associated with different and heterogeneous resources. To obtain such resources, firms must establish an external network to acquire necessary knowledge and skills. In this paper, we develop a theoretical model linking network orientation, organisational improvisation, ambidexterity and competitive tension. We postulate that organisational improvisation has a mediating effect and competitive tension is a moderator. Empirical results (N = 340) show that (1) network orientation leads to both exploratory and exploitative innovations, (2) the above effect is mediated by organisational improvisation and (3) competitive tension positively moderates the effect between network orientation and organisational improvisation.

The health and ecological harms created and spread by firms active in many unhealthy commodity industries (UCIs) have received considerable attention from the public health community. However, less focus has been paid to analysing the distribution of wealth and income – important social and economic determinants of health – by these industries. This study aimed to examine long-term trends in wealth and income distribution by publicly listed corporations active in four UCIs: fossil fuels; tobacco; ultra-processed foods; and alcohol. Quantitative analysis of a range of data was conducted for firms listed on stock exchanges in the United States (US). Wealth and income distribution metrics were analysed at the industry level, including effective corporate tax rates and shareholder value ratios. The equity ownership structures and investor location of 20 of the largest firms were also explored. Since the 1980s, US-listed firms in the examined UCIs have distributed much less of their wealth and income to governments and much more to shareholders and investors mostly based in high-income countries. The study provides evidence that firms active in UCIs create a 'double burden of maldistribution': their externalised social and ecological harms disproportionately affect disadvantaged population groups and governments in low- and middle-income countries; whilst, simultaneously, they are increasingly transferring wealth and income to a group over-represented by a small and privileged elite. The identified distributive injustice warrants increased policy attention. [ABSTRACT FROM AUTHOR]

Objectives: Those underage should not use tobacco products, including electronic nicotine delivery systems. A technologically-based solution developed by Juul Labs Inc to restrict underage access seeks to automate transactions, structurally mandate age-verification, and limit the quantity of JUUL products purchased per transaction. A pilot of this standards-based approach, referred to as RACS™ (Retail Access Control Standards), was conducted to assess efficacy. Methods: RACS was implemented at 171 stores within 3 retail chains selling tobacco products in 3 states. "Secret shopper" compliance audits, in which a mystery shopper attempted to purchase JUUL products, were conducted at participating stores before and after implementation of RACS, to test compliance with age-verification and product-quantity limits. Audit failure rates were compared pre- and post-RACS implementation to assess effectiveness. Comparisons were made overall, by chain, state, and failure type. Results: A total of 3990 audits were conducted. We found large, statistically significant reductions (p < .001) in failure rates for age-verification and compliance with product-quantity limits after implementing RACS, as compared to pre- RACS rates, declining to near zero. Conclusions: Utilizing enhanced access controls can be part of a comprehensive, evidence-based tobacco-control strategy to address underage use of all tobacco products, including JUUL. ACKNOWLEDGMENT & CONFLICT OF INTEREST STATEMENT: Funding for this study was provided by Juul Labs Inc.

Background: A growing body of research has found a link between firearm availability and police shootings of citizens across place. The problem, however, is that the previous studies on the topic tend to suffer from several limitations: a near exclusive focus on citizen fatalities, units of analysis at the state or county levels, and a variety of proxy measures tapping into community-level firearm access. The current study set out to address these issues by examining the relationship between different forms of firearm availability and both fatal and nonfatal injurious police shootings of citizens at the city level. Methods: More specifically, it merged The Trace's "Missing Pieces" measures of guns reported lost and stolen to police as well as licensed firearms dealers across jurisdictions from the Bureau of Alcohol, Tobacco, Firearms, and Explosives as proxies for firearm availability with data on police shootings of citizens in California and Florida from California's URSUS system and the Tampa Bay Times' "Why Cops Shoot" database, respectively. Negative binomial regression analyses were performed on a sample of 253 cities across the two states and a sub-sample of cities with licensed firearms dealers. Results: Findings uncovered a small positive association between rates of federally licensed guns stores and the number citizens shot by police as well as police shooting incidents while controlling for several community-level measures (e.g., concentrated disadvantage, gun homicide rates). Rates of guns lost or reported stolen were generally not significantly associated with the outcome measures in the multivariate models. Conclusions: Firearm availability is a significant correlate of police shootings. Pooled counts of both citizens shot by police and police shooting incidents are heightened in jurisdictions with higher rates of licensed gun dealers, which may be due to the fact that all firearms sold in the USA first make their way to the public through these mechanisms. Such licensed gun dealers must be appropriately monitored and audited to reduce illicit behavior and prevent firearms from making their way into secondary markets. Addressing access to firearms can be meaningful for a host of gun-related morbidity and mortality outcomes, including police shootings of citizens. [ABSTRACT FROM AUTHOR]

Despite the orthopedics markets in the US and the EU reaching a plateau, the market size in countries such as Brazil, Russia, India, and China is steadily growing. As a result, major orthopedic companies are shifting their focus towards these markets and developing products tailored to their needs. However, a significant challenge associated with this new opportunity is the requirement for the development of more affordable prostheses compared to those sold in the US and Europe. With the introduction of these lower-cost models into the market, this article aims to assess their performance in comparison to traditional models. A literature review was conducted, analyzing four parameters—the Hospital for Special Surgery Score, Knee Society Score, Range of Motion, and Western Ontario and McMaster Universities Arthritis Index—to evaluate different models. The findings indicated that low-cost models perform either equally well or, in some cases, slightly worse than traditional ones. It is worth to mention that the existing literature on this topic is limited, resulting in a relatively small number of models and studies included in this specific study. Nevertheless, this latter serves as a valuable foundation for future in-depth analyses and investigations. [ABSTRACT FROM AUTHOR]

COVID-19 is the most devastating pandemic that affected humanity and the world economy. This paper aimed to study the time-varying connectedness between the COVID-19 vaccination, infection rate (INFR), and the case fatality ratio (CFR) in the United States and the stock market returns. We used COVID-19 daily confirmed number of infections, deaths, and vaccinations and the daily US stock market index return. A wavelet coherence approach was used to assess the co-movement of the US stock market with the COVID-19 vaccination, INFR, and the CFR. The COVID-19 vaccination, INFR, and CFR have a positive and significant influence on S&P 500 returns at the majority of business cycle frequencies with an in-phase relation. The wavelet coherence analysis uncovers strong and significant connectedness between COVID-19 vaccination rate and S&P 500 return. From an economic perspective, the US government should continue its intervention with their vaccination strategy, as it is beneficial for fighting the pandemic. This may lead to the recovery of the stock market as well as to the whole economy. [ABSTRACT FROM AUTHOR]

Research on family firms' employment practices remains equivocal with findings from studies framed on the basis of stewardship and socioemotional wealth (SEW) preservation perspectives suggesting that family firms are better employers than nonfamily peers, and findings from studies grounded on agency theory suggesting the opposite. Arguing that these two perspectives are not mutually exclusive, we theorize that, consistent with notions of compensating differentials, pay practices in family firms offer a compensatory balancing of lower base pay with pay forms and benefits signaling the kind of caring, support and long‐term commitment typical of such firms. Accordingly, while, consistent with an agentic perspective, pay rates in nonfamily firms may be higher than in family firms, consistent with the stewardship/SEW perspective, we argue that pay and benefits may be structured to offer greater long‐term reward security in family firms. Focusing on reward practices among employees in a single job in a single industry (i.e., truck drivers), we find that where there are differences, they generally favor family firms, with a significantly higher proportion of family firms paying on the basis of fixed salary (as opposed to more variable hourly/mile‐based rates), and with those firms paying hourly offering typical and "floor" rates higher than those offered by nonfamily firms. Implications for theory and practice are discussed. [ABSTRACT FROM AUTHOR]

Persons with disabilities (PWDs) are disproportionately unemployed, underpaid, and underemployed despite their desire and capacity to work. The U.S. federal/state vocational rehabilitation (VR) program, under the supervision of the Rehabilitation Services Administration (RSA), is charged with providing services to assist eligible PWDs (VR consumers) in achieving employment. Despite research showing that VR consumers closed to self-employment (vs. non-self-employment closures) have better outcomes, self-employment is often considered as a last resort. Moreover, some evidence suggests self-employment (like non-self-employment) outcomes are associated with VR consumers' gender and racial/ethnic identity. The objective of this study was to determine trends of case closures in self-employment among PWDs within the VR program from 2011–2013 to 2017–2019 and to examine the effects of gender and race/ethnicity on self-employment outcomes. Variables of interest were obtained from RSA's Case Service Report (RSA-911) data set for 2011, 2012, 2013, 2017, 2018, and 2019. Data were recoded and analyzed. The number of closures in self-employment declined significantly. Weekly earnings in self-employment increased. Time from application to closure in self-employment decreased. Differences in VR self-employment outcomes by race/ethnicity and gender were noted. Efforts should be made to increase competency in self-employment of VR counselors and promote self-employment within the VR program. [ABSTRACT FROM AUTHOR]

The number of music therapy private practices in the United States is growing. While it is thought that improving business skills can improve business success, it is not clear what business education was received by music therapy business owners (MTBOs). The purpose of this qualitative inquiry was to explore MTBOs business education in the United States and their views on business education for music therapists and music therapy students. Following an interpretivist theoretical framework, we conducted semi-structured interviews with 21 MTBOs representing all seven regions of the American Music Therapy Association. Using thematic analysis, we created five themes with supporting subthemes. Our findings indicate that the amount of business education participants received as students did not match the amount of business education they perceived necessary to be business owners, and that they sought out additional training from a variety of sources. Participants' views on music therapy business education and skills important for business ownership in the field of music therapy are explored. [ABSTRACT FROM AUTHOR]

The specific aim was to characterize retail purchases of red and processed meat and other major protein-rich foods in the U.S. and by state. Supermarket scanner data from grocery stores, supermarkets, and big box stores collected from 2017-2019 (NielsenIQ, New York, NY) was used to characterize retail purchases of red meat, processed meat, and other protein-rich foods in thirty-one states representative of US retail food sales. Red meat, processed meat, poultry, seafood, eggs, other meats, and non-meat foods (beans, nuts, seeds, meat alternatives) by weight accounted for 25.9%, 20.4%, 25.8%, 5.9%, 12.6%, 1.3%, and 10.1%, respectively of total sales in 2017-2019. Mean per capita purchases of red meat by weight was 30.1 g/d, ranging from 45.4 g/d in Mississippi to 21.9 g/d in New York. Mean per capita purchases of processed meat by weight was 23.8 g/d, ranging from 36.6 g/d in Mississippi to 15.2 g/d in California. We observed statistically significant correlations between red and processed meat purchases with cardiovascular mortality and colorectal cancer by state. Per capita retail purchases of red and processed meat appear to reflect a dietary pattern that is not consistent with current national and international dietary recommendations.

This article discusses four examples of risk regulations in the United States, namely vehicle emissions, appliance efficiency, chemical safety, and the labeling of genetically modified food. In each example, consumer or environmental regulations were initiated at the state level despite business opposition. But when faced with a multiplicity of state product regulations, the affected firms decided to support the expansion of federal regulations. They were willing to accept stronger federal standards in order to preempt individual states from enacting more stringent standards than the federal government. This, in turn, led to a conflict between firms who wanted federal preemption of state restrictions and states who wanted to be able to enact regulations more stringent than those of the federal government. The outcomes of each of these conflicts over the scope of federal preemption had important impacts on each multilevel governance regulatory regime. The ability of both levels of the American government to enact more innovative risk regulations – often referred to as dynamic federalism – has made it more likely that they will be strengthened.
