Multicultural teaching competence among undergraduate faculty: a convergent mixed methods study
Authors: Puhy Chandler , Prakash Nalini , Lacson Clarissa , Bradt Joke 
Published: November 2021

Purpose
Increased student diversity in universities across the USA has increased the need for post-secondary educators to develop multicultural teaching competence (MTC). Most studies of MTC focus on educators teaching grades K-12. The purpose of this study is to determine how faculty members rate themselves in terms of MTC, what multicultural knowledge and skills faculty report and how they integrate these skills into their teaching practice and what barriers exist to developing and implementing MTC. The purpose of this study was to examine the factors that impact undergraduate faculty integration of multicultural awareness and attitudes into their teaching practices to enhance student learning.

Design/methodology/approach
A convergent mixed methods study used survey and interview data from undergraduate faculty. Select items from the MTC Inventory (MTCI) and social justice scales (SJS) were administered. Interviews (N = 7) were transcribed and analyzed using thematic analysis. Quantitative and qualitative data were compared to examine convergence and divergence.

Findings
Quantitative results revealed undergraduate faculty’s awareness, knowledge and skills as indicated by percent agreement with items from the MTCI and SJS instruments. Qualitative findings included the following four themes: knowledge building, addressing diversity in the classroom, barriers and challenges, and needs and recommendations. Qualitative data corroborated or explained many of the quantitative results and provided insight into these trends and barriers that impact MTC.

Originality/value
This is the first study of its kind, to our knowledge, that has used a mixed methods research design to examine factors that impact MTCs and associated barriers among a sample of undergraduate faculty across disciplines in one urban university.
From east to west and back again: the effects of reverse culture shock on female Saudi Arabian university students studying abroad
Authors: Winkel Carmen , Strachan Laura , Aamir Siddiqua 
Published: November 2021

Purpose
The purpose of this study is to explore the experiences of Saudi Arabian university students returning home after having spent time away studying internationally. The investigation focused exclusively on female students who for diverse reasons were unable to complete their studies abroad.

Design/methodology/approach
A thematic analysis was applied to analyze the seven in-depth interviews conducted by the authors. By using an open coding method analytic patterns across the entire data set were identified and then analyzed.

Findings
The findings suggest that the students experienced reverse culture shock reintegrating and assimilating into their former lives in the Kingdom of Saudi Arabia and its conservative culture. This was especially surprising considering not one of the participants experienced culture shock when they first traveled to their host country – the USA, Canada or England.

Research limitations/implications
The study is limited to a small group of seven female undergraduates who are comparatively well educated and come from a middle and upper socioeconomic demographic. As a result, without additional research, the findings cannot be extended to groups outside of this demographic.

Practical implications
Students who have studied abroad need improved academic and social support networks when they return home, according to the findings. The authors want to raise awareness about the difficulties that students face upon their return. Teachers, counselors, and advisors need to be on the lookout for the symptomatology associated with these types of problems.

Social implications
Female Saudi students returning home after an extended period of study abroad face a variety of problems. They must fit into a restrictive, partriarchal culture in which they are not legally equal to men.

Originality/value
To date, there are no studies that shed light on reverse culture shock for students who returned to Saudi Arabia without a degree. Due to the large number of Saudi scholarship holders who study in English-speaking countries with government support, the study is the first attempt in this direction.
The management discourse: collective or strategic performance drive?
Authors: Verhoef Grietjie 
Published: November 2021

Purpose
The purpose of this paper is to engage with the discourse on the assumed existence of an distinct “African management” model. It critically deconstructs the concepts and submits an alternative strategy to address the need to understand what is happening in management of business in Africa.

Design/methodology/approach
Qualitative critical text analysis is used to understand the discourse on the nature of “African management” from the extant literature. The identity theory informs the understanding of the references to “African” as fundamental to identify a distinct management model. This analysis is supplemented by empirical case study research into successful African business.

Findings
Scholars failed to conceptualise what is “African”, and subsequently also what constitutes “African management”. This conceptual void undermines the critical reconstruction of a single African management model. Empirical research into actual management practices emerge as fundamental to systematic progress in this discourse. This research points to diverse management traditions converging into pragmatic practices.

Research limitations/implications
Only a limited number of case studies were conducted into management history in Africa. This paper argues for an extended research programme, but this is future work.

Practical implications
It suggests a research strategy for scholars in African business studies, business history and management history to collaborate towards making a solid contribution to the economic development of our continent.

Social implications
This research has the potential of forging collaboration in business among all of the people in Africa.

Originality/value
A critical text analysis is used to expose the conceptual lacunae that undermines progress in the discourse. This paper contributes to the literature on “African management” by systematically deconstructing the concept of “African identity” as a prerequisite to the management discourse. By signalling ethnic nostalgia, the critical reconceptualisation of Africanness offers an intellectually creative strategy out of the stalled discourse.
Servant leadership and its association with an environment of empathic care: an empirical analysis of the perspectives of mid-level practitioners
Authors: Silver Reginald , Martin Mark 
Published: November 2021

PurposeAt the nexus of servant leadership and empathic care, this paper aims to explore the perceptions that mid-level practitioners express regarding the role that servant leadership plays in fostering an environment of empathic care.Design/methodology/approachThe authors surveyed mid-level practitioners across a large integrated health system (n= 167). Through exploratory factor analysis, we identify factors that serve as antecedents to an environment of empathic care. The factor analysis was complimented with partial least squares structural equation modeling to test a theoretical model of empathic care.FindingsThe model explains approximately 37% of the variance observed in an empathic care environment (R2= 0.372). The authors identify key constructs within servant leadership that health-care leaders can focus their efforts on to promote an environment of empathic care.Originality/valueThis study answers multiple calls for more empirical research into servant leadership and is one of the few studies that explores servant leadership within an exogeneous context. This research focuses on the perceptions of mid-level providers, whereas most extant servant leadership and empathy research focuses on the perceptions of patients. The authors extend servant leadership theory in a health-care context and support prior findings that servant leadership is a multidimensional construct. The authors outline a sound methodological approach for investigating the linkage between specific principles of servant leadership that can serve as predictors for the creation of an environment of empathic care.

AbstractA 37‐year‐old Japanese man with a 3‐year history of diffuse cutaneous systemic sclerosis was admitted to our hospital with high fever, arthralgia, myalgia, and muscle weakness. A physical examination revealed facial erythema, Gottron’s sign, and mechanic’s hands in addition to skin sclerosis. Laboratory data revealed significantly elevated levels of creatine kinase and decreased complement. Anti‐RNP, anti‐Smith, anti‐DNA, anti‐β2‐glycoprotein 1, anti‐polymyositis (PM)/Scl75, and anti‐PM/Scl100 antibodies were detected. He also had urinary protein, interstitial lung disease, pericarditis, multifocal cerebral infarctions, and leukoencephalopathy. Thus, a diagnosis of overlap syndrome of diffuse cutaneous systemic sclerosis, dermatomyositis, and systemic lupus erythematosus with antiphospholipid syndrome was made. Because of the intractable course, he was treated with multiple immunosuppressive and immunomodulatory drugs, including three rounds of 1000 mg methylprednisolone pulse therapy. This is the first case report of anti‐PM/Scl antibody‐positive overlap syndrome of three major connective tissue diseases.

Published: November 2021

AbstractMycotoxin contamination in foods has posed serious threat to public health and raised worldwide concern. The development of simple, rapid, facile, and cost‐effective methods for mycotoxin detection is of urgent need. Aptamer‐based sensors, abbreviated as aptasensors, with excellent recognition capacity to a wide variety of mycotoxins have attracted ever‐increasing interest of researchers because of their simple fabrication, rapid response, high sensitivity, low cost, and easy adaptability for in situ measurement. The past few decades have witnessed the rapid advances of aptasensors for mycotoxin detection in foods. Therefore, this review first summarizes the reported aptamer sequences specific for mycotoxins. Then, the recent 5‐year advancements in various newly developed aptasensors, which, according to the signal output mode, are divided into electrochemical, optical and photoelectrochemical categories, for mycotoxin detection are comprehensively discussed. A special attention is taken on their strengths and limitations in real‐world application. Finally, the current challenges and future perspectives for developing novel highly reliable aptasensors for mycotoxin detection are highlighted, which is expected to provide powerful references for their thorough research and extended applications. Owing to their unique advantages, aptasensors display a fascinating prospect in food field for safety inspection and risk assessment.

Published: November 2021

AbstractPopulation differences in dental development between Black and White ethnic groups have been debated but not previously studied in the UK. Using inappropriate data for dental age estimation (DAE) could lead to erroneous results and injustice. Data were collected from dental panoramic radiographs of 5590 subjects aged 6–24 years in a teaching hospital archive. Demirjian stages were determined for left‐sided teeth and third molars and data collected regarding hypodontia and third molar agenesis. Third molar development in self‐assigned Black British, including other self‐assigned Black ethnicity, was compared with that of self‐assigned White British subjects. Data were compared for males and females in the two ethnic groups using T‐tests for Demirjian Stages A–G of third molar development and Mann‐Whitney tests for Stage H once a cut‐off age at the maximum age for Stage G had been imposed. Third molar development occurred earlier in subjects of Black ancestry compared to those of White ancestry. While both ethnic groups showed large age ranges for every third molar stage, in female subjects these generally occurred at least 1.5 years earlier, and in males at least one year earlier. Hypodontia and third molar agenesis were more prevalent in White British, but the ethnic difference in third molar development persisted in subjects with complete dentitions. This is a large study that confirms ethnic differences in a London population, emphasises the difficulties of establishing the 18‐year‐old threshold using DAE, and confirms the risk of overestimating the age of individuals of Black ethnicity using White ethnic reference data.
Influence of fat content and water activity on the heating pattern of model systems submitted to microwave heating
Authors: Pérez‐Reyes M.E. , Gómez‐Salazar J.A. , López‐Malo A. , Sosa‐Morales Maria Elena 
Published: November 2021

AbstractThis research analyzed the influence of fat content (1%, 3%, 5%, and 10%, w.b.) and of water activity (0.85, 0.90, 0.95, and 0.99) on the effectiveness of microwave heating within model systems (agar gel). Findings indicate that an increased fat content promotes more uniform heating in the model systems and results in longer heating times to reach the target temperature of 50°C. In the model systems with different aw values, the warming of the central model zone was slower while in the corners, heating was accelerated. Additionally, in these models, heating times increased as the aw was decreased.Practical ApplicationThe study of model systems allows for a detailed assessment of food when subjected to microwaves; and how heating is influenced by food properties such as aw and fat content. Findings indicate that changes in product formulation could improve the heating of ready‐to‐eat foods, either by increasing the fat content (better uniformity) or having high aw (shorter heating time).

Published: November 2021

AbstractClubroot caused by Plasmodiophora brassicae is one of the major diseases on cruciferous crops. This disease has been a problem all over the world and led to serious economic losses in cruciferous crop production. The improvement of clubroot management is dependent on the effectiveness of bioassays on pathogenicity or plant resistance. P. brassicae resting spore inoculum prepared from clubroot tissues was widely used in bioassays. Traditionally, resting spore concentration was measured by visual counting with a haemocytometer; however, this method is time‐consuming, labour intensive and with poor repeatability due to the tiny size of resting spores. In this study, we established a turbidimetric method to measure P. brassicae resting spore concentration of the inoculum. A regression curve was generated by plotting optical density of gradiently diluted resting spore suspension against the corresponding resting spore concentrations, which resulted in a logarithmic regression equation. This method was validated and proved to be robust and effective in determining resting spore concentration of different samples, and was further confirmed by bioassay of infection and clubroot development. In conclusion, we established a standard protocol to prepare P. brassicae inoculum and provided an effective method for resting spore concentration determination. The results of this study can be widely used in research activities on clubroot sustainable management when an effective assessment of P. brassicae biomass is needed.
Associations of common mental disorder with alcohol use in the adult general population: a systematic review and meta‐analysis
Authors: Puddephatt Jo‐Anne , Irizar Patricia , Jones Andrew , Gage Suzanne H. , Goodwin Laura 
Published: November 2021

AbstractBackground and AimsResearch has shown that alcohol use and common mental disorders (CMDs) co‐occur; however, little is known about how the global prevalence of alcohol use compares across different CMDs. We aimed to (i) report global associations of alcohol use (alcohol use disorder (AUD), binge drinking and consumption) comparing those with and without a CMD, (ii) examine how this differed among those with and without specific types of CMDs and (iii) examine how results may differ by study characteristics.MethodsWe used a systematic review and meta‐analysis. Cross‐sectional, cohort, prospective, longitudinal and case–control studies reporting the prevalence of alcohol use among those with and without a CMD in the general population were identified using PsycINFO, MEDLINE, PsyARTICLES, PubMed, Scopus and Web of Science until March 2020. Depression, anxiety and phobia were included as a CMD. Studies were included if they used a standardized measure of alcohol use. A random‐effects meta‐analysis was conducted to generate pooled prevalence and associations of AUD with CMD with 95% confidence intervals (CI). A narrative review is provided for binge drinking and alcohol consumptionResultsA total of 512 full‐texts were reviewed, 51 included in our final review and 17 in our meta‐analyses (n = 382 201). Individuals with a CMD had a twofold increase in the odds of reporting an AUD [odds ratio (OR) = 2.02, 95% CI = 1.72–2.36]. The odds of having an AUD were similar when stratified by the type of CMD (mood disorder: OR = 2.00, 95% CI = 1.62–2.47; anxiety/phobic disorder: OR = 1.94, 95% CI = 1.35–2.78). An analysis of study characteristics did not reveal any clear explanations for between‐study heterogeneity (I2 > 80%). There were no clear patterns for associations between having a CMD and binge drinking or alcohol consumption, respectively.ConclusionsPeople with common mental disorders (depression, anxiety, phobia) are twice as likely to report an alcohol use disorder than people without common mental disorders.
Curvature and competitiveness: Carbon taxes in cattle markets
Authors: Schaufele Brandon 
Published: November 2021

AbstractEnvironmental regulation can interact with agricultural markets to produce underappreciated competitiveness and leakage effects. This paper measures effective carbon tax stringency by structurally recovering the domestic supply schedule for a trade‐exposed beef cattle industry such that elasticities and carbon tax rates change with product prices (i.e., due to the curvature of the supply function). Two basic propositions from the economics of taxation—that excess burdens increase in elasticities and tax rates—are shown to cause the stringency of uniform carbon policy to vary nonlinearly with output prices. Based on the domestic supply function, the relationship between marginal excess burden, a measure of policy stringency from the industry's perspective, and product prices is estimated. Several policy‐relevant counterfactual scenarios are explored. Results show that with moderately high output prices, supply elasticities are small and the efficiency cost of a $40/tCO2e carbon tax (gross of environmental benefits) is less than $0.01 per dollar tax revenue. As prices decline, supply curves become increasingly elastic and marginal excess burdens grow rapidly.
Reference Points and Democratic Backsliding
Authors: Grillo Edoardo , Prato Carlo 
Published: November 2021

AbstractWe propose a theory of democratic backsliding where citizens' retrospective assessment of an incumbent politician depends on expectations that are endogenous to the incumbent's behaviour. We show that democratic backsliding can occur even when most citizens and most politicians intrinsically value democracy. By challenging norms of democracy, an incumbent can lower citizens' expectations; by not doubling down on this challenge, he can then beat this lowered standard. As a result, gradual backsliding can actually enhance an incumbent's popular support not despite but because of citizens' opposition to backsliding. This mechanism can only arise when citizens are uncertain enough about incumbents' preferences (e.g. owing to programmatically weak parties). Mass polarization, instead, can reduce the occurrence of backsliding while simultaneously increasing its severity.
Are adaptable employees more likely to stay? Boundaryless careers and career ecosystem perspectives on career adaptability and turnover

Published: November 2021

AbstractEmployees with higher career adaptability (CA) have been shown in previous research to be more likely to build high‐quality social exchange relations with current employers, thereby displaying a lower intention to leave. Based on boundaryless careers and career ecosystem perspectives, this study aimed to challenge and enrich the extant understanding of this important question by examining the mixed effects of CA on turnover behavior. Results from a three‐wave survey study with 179 Chinese employees show that after controlling the baseline turnover intention (Time 1), CA (Time 1) predicted both affective commitment and relative deprivation at Time 2 (6 months after Time 1), which in turn produced opposite effects on voluntary turnover behavior at Time 3 (12 months after Time 1). Moreover, the boundaryless career mindset positively moderated the relationship between CA and relative deprivation and strengthened the indirect positive effect of CA on turnover behavior via relative deprivation. These results offer a more comprehensive and balanced view of the mixed role of CA in employees' turnover behavior and carry important implications for human resource management.
Leading in times of crisis: How perceived COVID‐19‐related work intensification links to daily e‐mail demands and leader outcomes
Authors: Venz Laura , Boettcher Katrin 
Published: November 2021

AbstractThe COVID‐19 crisis brought numerous challenges to work life. One of the most notable may be the acceleration of digital transformation, accompanied by an intensification of e‐mail usage and related demands such as high e‐mail workload. While research quickly started to examine the implications of these changes for employees, another important group of stakeholders has been overlooked: leaders. We focus on leaders during the COVID‐19 crisis and examine how COVID‐19‐related work intensification links to leaders' e‐mail overload appraisal and finally exhaustion and transformational leadership, a leader behaviour especially needed in times of crisis. In a 5‐day diary study in September 2020, 84 leaders responded to daily surveys on 343 days. Results of multilevel analysis showed that perceived COVID‐19‐related work intensification was positively linked to worktime spent dealing with e‐mail and appraised e‐mail overload. E‐mail overload appraisal was positively related to leaders' exhaustion, but unrelated to their transformational behaviour. Day‐specific time spent dealing with e‐mail, however, was negatively related to transformational leadership. E‐mail overload appraisal mediated the relationship between COVID‐19‐related work intensification and exhaustion. Turning the focus on leaders during the COVID‐19 crisis, our study has important implications for the design of work of leaders in times of crisis and beyond.
