Temporalis muscle thickness predicts early relapse and short survival in primary CNS lymphoma
Authors: Bonm Alipi V , Menghini Anthony , Drolet Caroline E , Graber Jerome J
Published: October 2022

Background

Most patients with primary CNS lymphoma (PCNSL) achieve durable remission whereas a minority die in the first year. Sarcopenia is a powerful predictor of mortality in the brain and systemic cancers. Temporalis muscle thickness (TMT) is a validated radiographic measure of sarcopenia. We hypothesized that patients with thin TMT at diagnosis would have early progression and short survival.

Methods

Two blinded operators retrospectively measured TMT in 99 consecutive brain MRIs from untreated patients with PCNSL.

Results

We generated a receiver operator characteristic curve and chose a single threshold defining thin TMT in all patients as <5.65 mm, at which specificity and sensitivity for 1-year progression were 98.4% and 29.7% and for 1-year mortality were 97.4% and 43.5% respectively. Those with thin TMT were both more likely to progress (P < .001) and had higher rates of mortality (P < .001). These effects were independent of the effect of age, sex, and Eastern Cooperative Oncology Group performance status in a cox regression. Memorial Sloan Kettering Cancer Center score did not predict progression-free survival or overall survival as well as TMT. Patients with thin TMT received fewer cycles of high-dose methotrexate and were less likely to receive consolidation but neither variable could be included in the Cox regression due to violation of the proportional hazards assumption.

Conclusions

We conclude that PCNSL patients with thin TMT are at high risk for early relapse and short survival. Future trials should stratify patients by TMT to avoid confounding.
High-efficiency nonlocal reflection-type vortex beam generation based on bound states in the continuum
Authors: Li Tongyu , Wang Jiajun , Zhang Wenjie , Wang Xinhao , Liu Wenzhe , Shi Lei , Zi Jian
Published: October 2022

Momentum-space polarization vortices centered at symmetry-protected bound states in the continuum of a periodic structure, e.g. photonic crystal slab, provide a novel nonlocal approach to generate vortex beams. This approach enjoys a great convenience of no precise alignment requirements, although the generation efficiency of the nonlocal generators requires further optimization before the practical application. In this work, we propose a temporal-coupled-mode-theory-based guideline for high-efficiency nonlocal reflection-type vortex generator design. The conversion efficiency of the vortex beam is found to be limited by the ratio of the radiative loss to the intrinsic absorption in practical systems. To increase this ratio through mode selection and structure design, the photonic crystal slabs are theoretically designed and experimentally characterized, showing a maximum on-resonance conversion efficiency of up to 86%. Combining high efficiency with simple fabrication and no requirement for precise alignment, reflection-type photonic crystal slabs could offer a new and competitive way to generate vortex beams flexibly.

Authors: Lehmann Dena M , Cohen Nina , Lin I-Hsin , Alexander Shane , Kathuria Ritu , Kerpelev Marina , Taur Ying , Seo Susan K
Published: October 2022

Background

Candidemia is associated with morbidity and mortality in cancer patients. We analyzed adherence to the 2016 Infectious Diseases Society of America (IDSA) candidiasis guidelines and the reasons for guideline nonadherence. We also investigated whether matrix-assisted laser desorption/ionization–time of flight (MALDI-TOF) improved time to effective antifungal therapy compared with historical data (median, 43.2 hours).

Methods

Cancer patients with candidemia between 1/1/17 and 12/31/19 were included. Adherence to 7 individual IDSA guideline components was assessed. Composite IDSA guideline adherence (defined as meeting ≥6 guideline components) was also assessed. Charts were reviewed to examine reasons for noncompliance.

Results

Of 157 patients with candidemia, 150 (95.5%) had infectious disease (ID) consultation. The median total time from blood culture collection to antifungal initiation was 42.1 hours. Excluding 39 patients with short treatment due to death, there was 100% adherence with surveillance blood cultures, followed by antifungal susceptibility testing (117/118, 99.2%), initial appropriate therapy (117/118, 99.2%), antifungal duration (110/118, 93.2%), line removal (82/91, 90.1%), eye exams (93/118, 78.8%), and step-down therapy (69/94, 73.4%). A quarter (30/118) did not meet composite IDSA guideline adherence. Univariate logistic regression suggested a relationship between poor cancer prognosis and incomplete adherence to the 2016 IDSA candidiasis guidelines (odds ratio, 8.6; 95% CI, 1.6–47).

Conclusions

The addition of MALDI-TOF did not shorten time to effective antifungal therapy. Nearly all patients were seen by ID for candidemia. Poor cancer prognosis was a common factor for incomplete composite adherence to the 2016 IDSA candidiasis guidelines.
Long-Term Virological Treatment Outcomes in Adolescents and Young Adults With Perinatally and Non-Perinatally Acquired Human Immunodeficiency Virus
Authors: Weijsenfeld Annouschka M , Smit Colette , Wit Ferdinand W N M , Mudrikova Tania , Nellen Jeannine F J B , van der Valk Marc , Pajkrt Dasja
Published: October 2022

Background

Long-term viral suppression on antiretroviral therapy (ART) is not established among all people with human immunodeficiency virus (PWH). Young adults (18–24 years) are recognized as a group vulnerable for suboptimal virological treatment outcomes. The aim of this study is to evaluate longitudinal virological treatment outcomes and to identify risk factors for virological failure (VF) among young adults with non-perinatally and perinatally acquired human immunodeficiency virus (HIV) in the Netherlands.

Methods

We included individuals registered in the national ATHENA observational cohort from 2000 until 2020 who had entered care before the age of 25 years, who had received ART for at least 6 months with at least 2 available HIV ribonucleic acid measurements between the age of 18 and 24 years. We compared VF between age groups 12–17, 18–24, and 25–30 years. A multivariable generalized linear mixed model was used to evaluate risk factors for VF. Analyses were stratified by HIV acquisition mode.

Results

In total, 1174 non-perinatally PWH and 157 perinatally PWH were included. In 2020, VF rate was 7% in non-perinatally PWH young adults and 19% in perinatally PWH young adults. The adjusted risk for VF was significantly higher in those aged 18–24 compared to 25–30 years in both non-perinatally PWH (odds ratio [OR], 1.27; 95% confidence interval [CI], 1.07–1.50) and perinatally PWH (OR, 2.34; 95% CI, 1.48–3.71).

Conclusions

Young adulthood is a vulnerable period, with increased risk for VF, especially for perinatally PWH. The probability of VF decreased over time, but less for perinatally PWH compared to non-perinatally PWH.

Published: October 2022

Background

SARS-CoV-2 nucleocapsid antigen can be detected in plasma, but little is known about its performance as a diagnostic test for acute SARS-CoV-2 infection or infectious viral shedding among nonhospitalized individuals.

Methods

We used data generated from anterior nasal and blood samples collected in a longitudinal household cohort of SARS-CoV-2 cases and contacts. Participants were classified as true positives if polymerase chain reaction (PCR) positive for SARS-CoV-2 and as true negatives if PCR negative and seronegative. Infectious viral shedding was determined by the cytopathic effect from viral culture. Stratified by 7 days after symptom onset, we constructed receiver operating characteristic (ROC) curves to describe optimized accuracy (Youden index), optimized sensitivity, and specificity.

Results

Of 80 participants, 58 (73%) were true positives while 22 (27%) were true negatives. Using the manufacturer's cutoff of 1.25 pg/mL for evaluating infection, sensitivity was higher from 0 to 7 days (77.6% [95% confidence interval {CI}, 64%–88.2%]) than from 8 to 14 days (43.2% [95% CI, 31.1%–54.5%]) after symptom onset; specificity was unchanged at 100% (95% CI, 88.1%–100%). This test had higher sensitivity (100% [95% CI, 88.4%–100%]) and lower specificity (65% [95% CI, 40.8%–84.6%]) for infectious viral shedding as compared with infection, particularly within the first week of symptom onset. Although the presence of N-antigen correlated with infectious viral shedding (r = 0.63; P < .01), sensitivity still declined over time. Additional cutoffs from ROC curves were identified to optimize sensitivity and specificity.

Conclusions

We found that this SARS-CoV-2 N-antigen test was highly sensitive for detecting early but not late infectious viral shedding, making it a viable screening test for community-dwelling individuals to inform isolation practices.
Rice GLUCAN SYNTHASE-LIKE5 promotes anther callose deposition to maintain meiosis initiation and progression
Authors: Somashekar Harsha , Mimura Manaki , Tsuda Katsutoshi , Nonomura Ken-Ichi
Published: October 2022

Callose is a plant cell wall polysaccharide whose deposition is spatiotemporally regulated in various developmental processes and environmental stress responses. The appearance of callose in premeiotic anthers is a prominent histological hallmark for the onset of meiosis in flowering plants; however, the biological role of callose in meiosis remains unknown. Here, we show that rice (Oryza sativa) GLUCAN SYNTHASE LIKE5 (OsGSL5), a callose synthase, localizes on the plasma membrane of pollen mother cells (PMCs) and is responsible for biogenesis of callose in anther locules through premeiotic and meiotic stages. In Osgsl5 mutant anthers mostly lacking callose deposition, aberrant PMCs accompanied by aggregated, unpaired, or multivalent chromosomes were frequently observed and, furthermore, a considerable number of mutant PMCs had untimely progress into meiosis compared to that of wild-type PMCs. Immunostaining of meiosis-specific protein HOMOLOGOUS PAIRING ABERRATION IN RICE MEIOSIS2 in premeiotic PMCs revealed precocious meiosis entry in Osgsl5 anthers. These findings provide insights into the function of callose in controlling the timing of male meiosis initiation and progression, in addition to roles in microsporogenesis, in flowering plants.
Using theory to understand how policy change happens: Insights from agricultural research for development
Authors: Douthwaite Boru , Proietti Claudio , Polar Vivian , Thiele Graham
Published: October 2022

Influencing policy is an important scaling mechanism. However, if a program is to plausibly claim that it has or can influence policy, it needs to explain how. This is not straightforward because of the complex nature of policy change. Scholars suggest the use of theory to help answer the ‘how’ question. In this article, we show how, in practice, a middle-range policy change theory—Kingdon’s Policy Window theory—helped us model the workings of four outcome trajectories that produced agricultural policy outcomes in four cases. By providing a common framework, the middle-range theory helped accumulate learning from one evaluation to the next, generating specific and generalizable insights in the process. Accumulation learning in this way can help organizations become more convincing in the proposals they write to donors, more accountable and better able to identify and deliver on their goals.
Claims to (S)expertise in the British Sex Survey, c. 1960s–1990s
Authors: Jones Katherine
Published: October 2022

This article focuses on one main producer of knowledge about sexual subjects in the twentieth century: the social sciences. Sociological interest in issues relating to sex and sexuality intensified in the 1950s, along with the rise of post-war social science deployed to gather information on a changing post-war British nation. Family planning surveys were central to this new academic sociology, and increasingly framed women respondents as experts on family planning practices. This article argues that social surveys related to contraceptive and sexual health practices became increasingly interested in questions of subjectivity from the 1970s, reflecting a broader shift in the social sciences. This led researchers to turn their attention towards men as valid contributors. In doing so, this article charts the development of sexual knowledge and makes broader interventions into the history of knowledge production, by providing insights into the changing ideas regarding legitimate sources of knowledge and expertise.
miRNA-141-5p Affects the Levels of Neutrophil Elastase in Preeclampsia by Regulating MAPK1
Authors: Cheng Keyan , Cui Jialei , Zhou Wenli , Liu Huiqiang , Yang Taotao , Wang Yonghong
Published: October 2022

Objective

The objective of this study was to investigate the expression levels of microRNA-141-5p(miRNA-141-5p), MAPK1 and neutrophil elastase in patients with and without preeclampsia (PE), and the relationship between miRNA-141-5p and MAPK1 with respect to the secretion of elastase by neutrophils in patients with PE.

Methods

Thirty patients with PE and 30 healthy pregnant (HP) women were recruited from The Second Hospital of Shanxi Medical University, Taiyuan, China, between February 2017 and July 2018. Neutrophils were isolated from 8 mL peripheral blood samples and cultured. We recorded neutrophil count and morphology during culture. Apoptosis was detected by flow cytometry in different groups at 0, 24, and 48 h. The expression levels of elastase were detected in neutrophils by enzyme-linked immunosorbent assay, whereas the expression levels of miRNA-141-5p in peripheral blood neutrophils were detected by real-time polymerase chain reaction. We used TargetScanHuman Release 7.2 to analyze the target genes of miRNA-141-5p. The expression of MAPK1 in peripheral blood neutrophils was detected by western blotting. Data were analyzed by SPSS version 21.0 software, and comparisons between groups were carried out with the Student t test.

Results

There was no significant difference between the PE and HP groups (P > 0.050) with regard to age or body mass index. The weight of newborns in the PE group (2846.00 ± 600.00 g) was significantly lower than that in the HP group (3055.00 ± 230.68 g). The number of neutrophilic granulocytes(NGs) in blood samples from the PE group was significantly higher than that in the HP group (P = 0.003). There was no significant difference between the groups with regard to morphology. Apoptosis in the PE group was delayed when compared with the HP group at different time points. The P value of apoptosis in the PE and HP groups were respectively 0.790, < 0.001 and 0.030 at 0 h, 24 h and 48 h. The expression levels of miRNA-141-5p in the PE group were significantly lower than those in the HP group (P < 0.050). The expression levels of MAPK1 in neutrophils from the PE group were significantly higher than those in the HP group (P < 0.050) by western blot. The expression levels of elastase in neutrophils from the PE group were significantly higher than those in the HP group (P < 0.050). Furthermore, the number of NGs in peripheral blood from the PE group was higher than that of the HP group; however, the levels of apoptosis were lower. The expression levels of miRNA-141-5p in NGs decreased, the expression of MAPK1 increased, and the secretion of neutrophil elastase in the NG medium increased in the PE group than those in the HP group.

Conclusion

Collectively, our analysis suggested that miRNA-141-5p may be involved in the pathogenesis of PE by regulating the MAPK1 signaling pathway to activate neutrophils and increase the secretion of elastase.
Impact of board attributes and managerial ownership on cash holdings: empirical evidence using GMM and quantile regressions
Authors: Talbi Dorra , Menchaoui Ines
Published: October 2022

Purpose

The purpose of this study is to examine the impact of board attributes and managerial ownership on cash holdings.

Design/methodology/approach

The present study examines a sample of 70 listed firms in Saudi Arabia observed during the period stretching from 2006 to 2016. To test the hypotheses, the authors used generalized method of moments and quantile regressions.

Findings

The empirical results reveal that corporate governance (CG) mechanisms are inefficient in the Saudi context. In fact, the authors found that board size, board independence, duality and managerial ownership impact positively and significantly cash holdings. Additionally, quantile regressions confirm the results that at certain thresholds, CG mechanisms are not efficient in protecting shareholders’ interests. Shariah compliance is found to moderate negatively and significantly the studied relationship.

Originality/value

This study helps to not only clarify and help decision-makers to see the importance of corporate cash management but also to identify the limits of the CG mechanisms put in place.

The integrative approach in the study of resilience in female entrepreneurship
Authors: Nassif Vânia Maria Jorge , Garçon Márcia Maria
Published: October 2022

Purpose

This paper aims to understand resilience in entrepreneurial behavior and the major adversities faced by women entrepreneurs and identify theoretical and empirical bases that support the use of the integrative approach as appropriate to studies of resilience in women entrepreneurs.

Design/methodology/approach

In this exploratory-theoretical study, the authors adopted a narrative review of the literature on Female Entrepreneurship, Business and Resilience. The databases researched were: Web of Science, Social Citation Index and Scopus, of which 52 were submitted to analysis through techniques of comparison and contrast between theory, classical studies and applied research.

Findings

The study illuminates the concept of resilience aligned with entrepreneurship and the major adversities of female entrepreneurship. It also indicates the competence of the integrative approach in investigating and analyzing resilience as a complex, functional and emotional phenomenon between women entrepreneurs and their business environment.

Research limitations/implications

This study indicates that the integrative approach can offer an explanatory device about the relationships between affectivity and cognition in the resilient behavior of women when encountering difficulties in the entrepreneurial process. It also indicates paths for future research that can empirically prove the degree of these constructs in the resilient behavior of women entrepreneurs, having the difficulties related to the gender stereotype as a point of interest.

Practical implications

The contribution to the managerial field is to alert women entrepreneurs about the need to understand the role of affectivity and cognition in facing adversity to strengthen their resilient behavior.

Social implications

The contribution to the managerial field is to alert women entrepreneurs about the need to understand the role of affectivity and cognition in facing adversity to strengthen their resilient behavior.

Originality/value

This study provides original evidence that cognitive and affective aspects influence women’s entrepreneurial behavior with the same degree of importance. Therefore, they must be investigated jointly. This discovery brings relevance to theoretical and empirical studies on this topic.
Generational differences in work values in the Korean Government sector
Authors: Park Sohee , Park Sunyoung
Published: October 2022

Purpose

The purpose of this study is to compare the perceptions of work values among different generational groups (Boomers, Generation 386, Generation X and Millennials) in the Korean Government sector.

Design/methodology/approach

Using a sample of 1,084 employees working in the Korean Government sector, this study compared generational differences in work values with seven dimensions: detail, aggressiveness, team orientation, outcome orientation, people orientation, innovation and organization orientation.

Findings

This study found that Millennials had the most significant differences in aggression, team-orientation, innovation and organization-focus, compared to Generation 386. Millennials were less aggressive and more team-oriented and innovative than Generation 386. Millennials also put less value on the organization compared to Generation X and Generation 386, indicating that Millennials are less willing than other generations to sacrifice their individual needs for the needs of the organization. Generation X had higher values in supportiveness, fairness and respect for individuals than Generation 386.

Originality/value

This study adds to the current literature by empirically examining how employees’ work values are influenced by the generational differences of the workers.

Published: October 2022

Purpose

This paper aims to describe the unique health challenges facing female commercial sex workers (FSWs), including issues related to their marginalisation and difficulty accessing health care. It proposes solutions to some of these problems.

Design/methodology/approach

This paper addresses this sensitive subject through the methodology of a literature review, drawing on a variety of relevant published literature to inform a modern understanding of the current health challenges faced by this population.

Findings

This paper discusses issues around criminalisation of commercial sex workers, complexities of family planning, sexually transmitted infection prevention, mental health and substance abuse and how increasing health-care worker awareness of the health needs of this vulnerable population can be a positive step in building trust within this relationship. Although adoption of the proposed recommendations put forth in this paper may help to eliminate some of the barriers encountered by female sex workers, further research is recommended.

Originality/value

The subject of commercial sex worker health care is neglected in the academic literature. This review explores the topic in an open and balanced manner and presents a broad and updated overview of the current health-care challenges faced by FSWs as well as opportunities for optimising access and quality of sex worker health care.
A tale of two schools: curriculum deliberation and school-level orientation in transforming knowledge through lesson study
Authors: Goh Rachel , Fang Yanping
Published: October 2022

Purpose

The purpose of this paper is to examine how teachers engaged in curriculum deliberation through lesson study (LS) and how different types of teacher knowledge were elicited, co-constructed and transformed in integrated ways across LS stages. It also clarifies how different school-level orientations influence the nature, depth and scope of the deliberation.

Design/methodology/approach

The study adopted an interpretive qualitative case study approach involving two schools, employing participant observations of LS cycles and post-LS teacher interviews. Thematic analysis and analytical coding were conducted.

Findings

The two cases revealed core features of curriculum deliberation trajectories enabled by LS: problem identification, planning to unlock the educative potential of content and reflection on enactment for improvement. The types of teacher knowledge that informed deliberation on English language learning were uncovered to reveal LS teams' initial comprehension, collective reasoning and actions, and new knowledge derived. Pedagogical content knowledge was prominently drawn on in unlocking curriculum potential and transformed with the knowledge of student learning gained from the live lesson observations. The school-level orientations were found to influence the extent to which teachers can interrogate existing practices and co-construct knowledge.

Originality/value

The study offers a nuanced understanding of curriculum thinking in LS teams, which is enabled by processes that construct the dialogic space for coordinating curriculum commonplaces to transform content into pedagogical representations to cultivate students' future capacities. It highlights the importance of viewing sustainable LS from an interconnected perspective that calls attention to the social contexts of deliberation.
Challenges of undocumented immigrants in Canada and the USA during the COVID-19 pandemic: a review
Authors: Marfo Emmanuel Akwasi , Fernandez-Sanchez Higinio , Annor Bridget Osei Henewaa
Published: October 2022

Purpose

Pandemics pose challenges to all groups of people and all aspects of human lives. Undocumented migrants are likely to face more challenges during global pandemics. The purpose of this paper is to explore the possible challenges of undocumented immigrants in Canada and the USA in the ongoing COVID-19 pandemic.

Design/methodology/approach

From existing literature, the authors examined the challenges of undocumented migrants in Canada and the USA and suggested recommendations to address those challenges at both policy and national levels.

Findings

The undocumented status of some international immigrants makes them vulnerable in their host nations. They face myriad challenges in their host countries, spanning from economic, health, social isolation and employment challenges, and these are further exacerbated during pandemics such as the ongoing COVID-19. The provision of culturally sensitive and safe policies may support this particular population, especially in times of crisis like the COVID-19 pandemic.

Originality/value

This paper provides critical insights into the possible intersections that worsen the vulnerability of undocumented migrants in pandemic crises like COVID-19. Further, this review serves to initiate the discourse on policy and interventions for undocumented immigrants during pandemics or disease outbreaks.
Demystifying the authenticity experience of locally guided wine tours in the meal-sharing economy
Authors: Cifci Hatice , Kandemir Altunel Gizem , Taspinar Oguz , Cifci Ibrahim
Published: October 2022

Purpose

The purpose of this study is to demystify the authenticity dimensions of wine experience with the locally guided tour in the meal-sharing economy, drawing on travellers' online reviews at Withlocals for French locally guided wine tours.

Design/methodology/approach

The qualitative research approach was performed through the thematic analysis of 940 online reviews from Withlocals. The coding phase was completed based on a three-step coding process (i.e. open, axial and selective coding), as all reviews that were gathered were related to locally guided wine tours rather than only wine-sharing activities.

Findings

The findings of this study demonstrated four interrelated authenticity dimensions: the taste of terroir, local atmosphere, oenological knowledge and local insight. The results of this study also notably showed that all reviews were primarily positive; travellers expressed their satisfaction with wine tours at Withlocals and often mentioned their re-purchase intentions as well as advising wine tours in the meal-sharing economy.

Practical implications

Several worthy theoretical and practical implications were discussed for local tour guides to improve their tour quality more authentically. The results also demonstrate that locally guided wine tours in the meal-sharing economy were regarded as a multidimensional activity that provides a better discovery of a wine destination.

Originality/value

Despite the large volume of generic meal-sharing economy experience studies, the authenticity experience of the locally guided wine tours has been surprisingly omitted by scholars. Therefore, this study contributes to the sharing economy literature through wine experience by addressing the authenticity dimensions of the locally guided wine tours in the meal-sharing economy.
Towards corpora creation from social web in Brazilian Portuguese to support public security analyses and decisions
Authors: de Carvalho Victor Diogho Heuer , Costa Ana Paula Cabral Seixas
Published: October 2022

Purpose

This article presents two Brazilian Portuguese corpora collected from different media concerning public security issues in a specific location. The primary motivation is supporting analyses, so security authorities can make appropriate decisions about their actions.

Design/methodology/approach

The corpora were obtained through web scraping from a newspaper's website and tweets from a Brazilian metropolitan region. Natural language processing was applied considering: text cleaning, lemmatization, summarization, part-of-speech and dependencies parsing, named entities recognition, and topic modeling.

Findings

Several results were obtained based on the methodology used, highlighting some: an example of a summarization using an automated process; dependency parsing; the most common topics in each corpus; the forty named entities and the most common slogans were extracted, highlighting those linked to public security.

Research limitations/implications

Some critical tasks were identified for the research perspective, related to the applied methodology: the treatment of noise from obtaining news on their source websites, passing through textual elements quite present in social network posts such as abbreviations, emojis/emoticons, and even writing errors; the treatment of subjectivity, to eliminate noise from irony and sarcasm; the search for authentic news of issues within the target domain. All these tasks aim to improve the process to enable interested authorities to perform accurate analyses.

Practical implications

The corpora dedicated to the public security domain enable several analyses, such as mining public opinion on security actions in a given location; understanding criminals' behaviors reported in the news or even on social networks and drawing their attitudes timeline; detecting movements that may cause damage to public property and people welfare through texts from social networks; extracting the history and repercussions of police actions, crossing news with records on social networks; among many other possibilities.

Originality/value

The work on behalf of the corpora reported in this text represents one of the first initiatives to create textual bases in Portuguese, dedicated to Brazil's specific public security domain.
Integrating external actors into the microfoundations of practice transfer in MNEs: a research agenda
Authors: Hassan Ahmed A.F.M. , Fortwengel Johann
Published: October 2022

Purpose

The transfer of organizational practices in multinational enterprises (MNEs), typically from the headquarters to foreign subsidiaries, has been a key theme in international business (IB) literature. Research on this topic increasingly acknowledges the important role of organizational actors external to the focal MNE. Furthermore, there is a growing interest in the microfoundational underpinnings of practice transfer as an important phenomenon in IB. This paper aims to bring together these two emerging research trends to outline an exciting and important avenue for further research.

Design/methodology/approach

This is a conceptual paper. This paper builds on prior empirical research to theorize different types of involvement of external organizational actors in the transfer process. This study further identifies specific mechanisms that lead to transfer outcomes in terms of practice adaptation.

Findings

The authors develop conceptual arguments regarding the role of external actors in the microfoundations of transfer. The involvement of external organizational actors can be either direct or indirect, and it can occur in the initiation stage at headquarters level and/or in the implementation stage at subsidiary level. The authors theorize how the involvement of external organizational actors in the transfer process shapes practice adaptation as a key outcome. This study summarizes the theorization with the help of propositions, and this study also identifies a set of research questions that can guide future research on this increasingly important topic.

Originality/value

This paper contributes to the literature by developing a research agenda to open up the black box regarding the role of external actors in the microfoundations of practice transfer in MNEs.
Sustainability and profitability of Malaysia crude palm oil supply chain management: system dynamics modelling approach
Authors: Mareeh Hadi Yahya Saleh , Prabakusuma Adhita Sri , Hussain Mohammad Delwar , Patwary Ataul Karim , Dedahujaev Akmalhon , Aleryani Rami Abdullah
Published: October 2022

Purpose

The agriculture industry has a considerable impact on Malaysia’s economy, as seen by its contribution of roughly 8.2% of gross domestic product in 2018 and its potential to absorb 11.09% of Malaysian labor in the same year. This study aims to simulate rising output in a system model of sustainable and profitable crude palm oil (CPO) supply chain management (SCM) and to formulate policy solutions to build sustainable and profitable SCM of Malaysian CPO.

Design/methodology/approach

This research included both primary and secondary data. This study used the dynamic system model to simulate palm oil land expansion, replanting policies and environmentally friendly growing techniques.

Findings

This study’s findings suggest that the dynamic system model of Malaysia’s CPO’s sustainable and profitable SCM is valid when its structure and performance are tested. The fifth scenario provides the best results, with the most significant net benefit value compared to the other scenarios.

Originality/value

The ideal policy alternative is replanting sustainable agricultural practices without burning technologies during new land clearing to achieve the best net advantages.
Linking leader-member exchange and work–nonwork balance: the mediating role of thriving at work and the moderating role of gender
Authors: Di Milia Lee , Jiang Zhou
Published: October 2022

Purpose

The authors tested (1) the mediating role of thriving in the association between leader-member exchange (LMX) and work–nonwork balance (WNWB) and (2) the moderating effect of gender in the relationship between LMX and thriving.

Design/methodology/approach

Cross-sectional data were collected from six separate participant groups across an eight-month period (n = 522). Data analysis included confirmatory factor analysis to assess the construct validity of the proposed three-factor model. Hierarchical regression and the PROCESS macro were used to test three hypotheses.

Findings

The authors found thriving mediated an indirect effect of LMX on WNWB. In addition, we found that the relationship between LMX and thriving was moderated by gender, such that the relationship was found for females. Overall, the authors identified a moderated-mediation effect indicating an indirect effect of LMX on WNWB via thriving for females.

Research limitations/implications

Cross-sectional design suggests their results are theory driven. The authors suggest future studies replicate the study employing experimental designs.

Practical implications

The authors suggest organisations develop programs to enhance leadership and thriving capabilities as tools to manage WNWB.

Originality/value

The authors add to the thriving literature by revealing gender differences in the effectiveness of relational resources (i.e. LMX) in fostering employee thriving. Furthermore, the authors extend the efficacy of thriving beyond the workplace to include WNWB. The authors demonstrate the skills and knowledge acquired at work can be used to lessen the impact of WNWB.

Authors: Baah Benjamin , Acheampong Alex , Osei-Asibey Dickson , Afful Aba Essanowa
Published: October 2022

Purpose

Employee unsafe behaviours and failure to adhere to safety standards resulting from poor safety perception among employees contribute to the high rate of accidents in the construction industry. This study seeks to examine the role of respectable engagement in improving construction workers' safety perceptions in the Ghanaian Construction Industry.

Design/methodology/approach

The study adopted a quantitative research method where survey questionnaires were administered to respondents. Sixty-six construction workers who were actively involved in ongoing construction projects in Kumasi and Greater Accra regions of Ghana were selected through stratified purposive sampling. The analytical tools utilised in the data analysis include a one-sample t-test, descriptive statistics and mean score ranking.

Findings

The study identified five key drivers and strategies of respectable engagement from pertinent literature. The findings confirmed that all these drivers and strategies play a key role in improving workers' safety perception. The study further revealed that improving employees' safety perception will enhance and sustain their awareness of the organisation's commitment to health and safety. Employees will therefore portray positive safety behaviour by adhering to the safety standards of their organisation.

Practical implications

The findings of this study will contribute to construction site safety improvement by informing contractors, site supervisors and other stakeholders of their role and the need to improve their worker's safety perception.

Originality/value

This research is unique in that; it identifies the role of respectable engagement in improving construction workers' safety perception. This research creates awareness among management and site supervisors on the need to be present for their workers, affirm them, attend to their needs, understand and appreciate them, and communicate and listen to them.
Agency and career indecision among biological science graduate students
Authors: Griffin Kimberly A. , Miller Candace , Roksa Josipa
Published: October 2022

Purpose

The purpose of this study is to examine how student agency influences career decision-making for doctoral students in biological sciences. The authors address the following questions: How do biological science graduate students navigate career indecision? And how does agency relate to their experiences with career indecision?

Design/methodology/approach

The authors analyzed interview data collected from 84 PhD biology graduate students. Researchers used a grounded theory approach. After open codes were developed and data were coded, code reports were generated, which were used to determine themes.

Findings

More than half of the sample had not committed to a career path, and undecided students were bifurcated into two categories: Uncommitted and Uncertain. Uncommitted graduate students demonstrated agency in their approach and were focused on exploration and development. Uncertain students demonstrated less agency, were more fearful and perceived less control and clarity about their options and strategies to pursue career goals.

Practical implications

Findings suggest some forms of indecision can be productive and offer institutional leaders guidance for increasing the efficacy of career development and exploration programming.

Originality/value

Research on doctoral student career decision-making is often quantitative and rarely explores the role of agency. This qualitative study focuses on the relationship between student agency and career indecision, which is an understudied aspect of career development.
MEMS‐based 3‐C borehole gravimeter development
Authors: Yu Gang , Hu Fangjing , Tu Liangcheng , Zhao Guo , Chen Juan
Published: October 2022

A micro‐electro‐mechanical‐based 3‐C borehole gravimeter has been developed in China for mineral and hydrocarbon exploration. The 3‐C borehole gravimeter is composed of a three‐axis gravity sensor chip based on a deep silicon etching technique, high‐precision capacitive displacement sensing and weak signal detection circuitry. The gravity‐sensing chip is a silicon‐based integrated spring‐mass block system. Silicon wafer is etched by the micro‐nanofabrication technique to form a high collimation groove. The size of the gravity‐detecting mass block in the sensitive element plays a decisive role in the thermal noise level of the instrument. Deep silicon processing technique can produce a thicker silicon mass block (500 μm), which can obtain a larger mass block in the same area compared with the traditional silicon surface processing technique (10–100 μm). The out diameter of the final tool is 50 mm with 10,000 mGal measurement range, 155°C temperature and 100 MPa pressure rating. Apart from the 3‐C micro‐electro‐mechanical gravity sensor, a 3‐C fluxgate magnetic sensor is also integrated into the downhole tool. This allows us to measure both 3‐C gravity field and 3‐C magnetic field downhole simultaneously and conduct joint inversion of both the downhole 3‐C gravity and 3‐C magnetic data during the data processing stage. The prototype tool was tested in a borehole up to 850 m depth, and the 3‐C gravity sensor inside the tool can measure the vibration of the environment during the stationary measurement downhole. The first test data set shows repeatability near 800 m depth, which verifies the adaptability of the micro‐electro‐mechanical‐based gravimeter to the down instrument environment.
Impact of energy infrastructure investments on renewable electricity generation in major Asian developing economies
Authors: Song Yuegang , Shahzad Umer , Paramati Sudharshan Reddy
Published: October 2022

The prime objective of this research is to empirically investigate the impact of energy infrastructure investments (public‐private‐partnership) on renewable electricity generation in major Asian developing economies (China, India, Indonesia, Malaysia, Pakistan, the Philippines, and Thailand). In doing so, we use the annual data of variables from 1993 to 2017. To achieve the study objective, the authors employ numerous panel econometric approaches such as the Grouped‐Mean and Augmented Mean Group estimators. The overall conclusion of the findings is that investments in energy infrastructure play a significant role in promoting renewable electricity generation in Asian developing economies. The results also reveal that financial development, economic development, and openness further rise renewable electricity generation. Based on the findings, the authors attempted to provide novel implications for the promotion of energy infrastructure investments and sustainable development policies for the Asian developing economies. For instance, the authors suggest that governments and policy makers should realise the significance of greener energy and promote investments via public‐private partnerships for renewable energy projects.
Knowing (with) the body: Sensory knowing in contraceptive self‐tracking
Authors: Algera Ellen
Published: October 2022

Scholars have criticised reproductive self‐tracking software applications (apps) for reducing embodied experiences to objective quantifications and leading to user self‐alienation. Building on scholarly work that underscores the sensory and affective dimension of self‐tracking, this ethnographic study explores how users of contraceptive self‐tracking apps come to know their bodies during their everyday tracking practices. By relating tracking data to embodied experiences and relating their experiences back to the data, users produce knowledge of their own lived hormonal physiology. Users learn to articulate how their body feels and acts, foregrounding their body as an instrument of knowing alongside technical devices used. Users also articulate how their body is affected by everyday factors such as personal behaviours, diet, sleep and stress, thereby enacting what I call situated health. By foregrounding people’s sensory and affective engagements with their data and their bodies through self‐tracking, this study contributes to understanding how reproductive self‐tracking may be meaningful to users as well as encourages a move beyond the hierarchical opposition between ‘objective’ numerical data and embodied, lived experiences.
