AbstractIntroductionAlthough the publication of systematic reviews (SR) and meta-analyses (MA) has substantially grown in Ethiopia, no robust study systematically characterized these SR and MA was conducted. Thus, we aimed to map publication outputs, collaboration networks, research hotspots, and most cited SR and MA of medicine and health sciences in Ethiopia.MethodsWe conducted a bibliometric study of SR and MA published up to December 31, 2021, and systematically searched via PubMed, PsycInfo, EMBASE, and Web of Science databases. We included all SR and MA in medicine and health sciences fields in Ethiopia irrespective of the authors’ affiliation and place of publication. Full records and cited references’ meta-data were extracted from the Web of Science Core Collection database. VOSviewer software was used to perform bibliometric analyses. The relevance of an item (e.g. author, country, or keywords) was measured by its weight based on frequencies using the full or binary counting method) and strength of the link between items was measured using total link strength.ResultsIn total, 422 SR and MA were published between 2001 and 2021 by 14 research groups (i.e. overall, 1,066 authors participated) who affiliated with institutions from 33 countries. The largest number of SR and MA were published by authors affiliated with Debre Markos University, University of Gondar and Bahir Dar University. In addition, strong collaboration was observed among authors affiliated with institutions in Ethiopia, the Netherlands, Australia, and Canada. The identified research hotspots were maternal and child health, depression and substance use, cardiometabolic diseases, infectious diseases, HIV/AIDS, hepatitis and nutrition. The most cited SR was about domestic violence against women published in 2015. The SR and MA were published in 160 journals, with a majority published in PLOS (11%) and BMC (25%) journals.ConclusionsIn this study, we provide a comprehensive summary of collaboration networks, research hotspots, and most cited SR and MA to gain a deeper understanding of the landscape of SR and MA research in Ethiopia. We believe that our study informs researchers, higher institutions, and policymakers about research hotspots and gaps in medicine and health sciences research in Ethiopia. The national and international collaboration is promising, and a concerted effort among researchers, policymakers and funding agencies could increase research outputs and broaden research areas.
The Eucalyptus grandis chloroplast proteome: leaf development and seasonal variations
Authors: Baldassi Amanda Cristina , Balbuena Tiago Santana 
Published: February 2022

AbstractChloroplast metabolism is very sensitive to environmental fluctuations and is intimately related to plant leaf development. Characterization of the chloroplast proteome dynamics may contribute to enlarge the understanding on plant adaptation to different climate scenarios and leaf development processes. Herein, we carried out a discovery-driven proteome analysis of the Eucalyptus grandis chloroplast proteome during leaf maturation and throughout different seasons of the year. The chloroplast proteome from young leaves differed the most from all assessed samples. Most up-regulated proteins identified in mature and young leaves were those related to catabolic-redox signaling and biogenesis processes, respectively. Seasonal dynamics revealed unique proteome features in the autumn and spring periods. The most abundant chloroplast protein in humid (wet) seasons (spring and summer) was a small subunit of RuBisCO, while in the dry periods (fall and winter) the proteins that showed the most pronounced accumulation were associated with photo-oxidative damage, Calvin cycle, shikimate pathway, and detoxification. Our investigation of the chloroplast proteome dynamics during leaf development revealed significant alterations in relation to the maturation event. Our findings also suggest that transient seasons induced the most pronounced chloroplast proteome changes over the year. This study contributes to a more comprehensive understanding on the subcellular mechanisms that lead to plant leaf adaptation and ultimately to Eucalyptus grandis productivity. Mass spectrometric data are available via ProteomeXchange under identifier PXD029004.
Mapping of promoter usage QTL using RNA-seq data reveals their contributions to complex traits
Authors: Kubota Naoto , Suyama Mikita 
Published: February 2022

AbstractGenomic variations are associated with gene expression levels, which are called expression quantitative trait loci (eQTL). Most eQTL may affect the total gene expression levels by regulating transcriptional activities of a specific promoter. However, the direct exploration of genomic loci associated with promoter activities using RNA-seq data has been challenging because eQTL analyses treat the total expression levels estimated by summing those of all isoforms transcribed from distinct promoters. Here we propose a computational framework for identifying genomic loci associated with promoter activities, called promoter usage quantitative trait loci (puQTL), using conventional RNA-seq data. By leveraging public RNA-seq datasets from the lymphoblastoid cell lines of 438 individuals from the GEUVADIS project, we obtained promoter activity estimates and mapped 2,592 puQTL at the 10% FDR level. The results of puQTL mapping enabled us to interpret the manner in which genomic variations regulate gene expression. We found that 310 puQTL genes (16.1%) were not detected by eQTL analysis, suggesting that our pipeline can identify novel variant–gene associations. Furthermore, we identified genomic loci associated with the activity of “hidden” promoters, which the standard eQTL studies have ignored. We found that most puQTL signals were concordant with at least one genome-wide association study (GWAS) signal, enabling novel interpretations of the molecular mechanisms of complex traits. Our results emphasize the importance of the re-analysis of public RNA-seq datasets to obtain novel insights into gene regulation by genomic variations and their contributions to complex traits.
The relevance of bilateral political relations between countries for the completion stage premium of cross-border mergers and acquisitions
Authors: Ding Zhenkuo , Hu Man , Huang Sheng 
Published: February 2022

PurposeThe purpose of this paper is to examine the influence of bilateral political relations on the completion stage premium of cross-border mergers and acquisitions(CSPCMA) and the moderating roles of cultural distance, trade openness and the nature of firm ownership for this relationship.Design/methodology/approachBased on a sample of 401 cross-border mergers and acquisitions (M&A) conducted by Chinese companies from 1995 to 2019 in the Statistical Data Center (SDC), this article used weighted least squares (WLS) to empirically test the impact of bilateral political relations between countries on the CSPCMA.FindingsThe better the target country of entry’s bilateral political relations with China, the lower the premium of the transaction price paid by Chinese companies at the completion stage of cross-border M&A. Among the moderators, the study found cultural distance positively moderates the relationship between bilateral political relations between countries and CSPCMA. The degree of trade openness of the target country negatively moderates the relationship between bilateral political relations between countries and CSPCMA. The negative relationship between bilateral political relations between countries and CSPCMA is stronger when the acquirer is a state-owned enterprise (SOE).Originality/valueThe findings of this study not only add to the knowledge about the relationship between bilateral political relations and corporate cross-border M&A premiums, but also have managerial implications for Chinese corporate managers to sustainably reduce corporate cross-border M&A premiums.
Family ownership and risk: the role of family managers
Authors: D'Este Carlotta , Carabelli Marina 
Published: February 2022

Purpose
This study aims to investigate the relationship between family managers and firms’ risk levels in a context characterized by low investor protection and firm opacity. Specifically, this paper examines whether the level of risk faced by firms is affected by family shareholders’ ownership stake and activism.

Design/methodology/approach
Corporate governance data were hand-collected for a sample of 90 Italian listed companies and 540 observations from the year 2018. Regression analysis was then used to test the research hypotheses.

Findings
This study provides evidence of a positive association between active family ownership and risk faced by sampled firms. This study also finds that the number of inside directors is negatively correlated with firms’ risk-taking. Overall, the results confirm family managers’ influence on firms’ risk choices and show consistency with theoretical arguments in favor of hiring professional managers to guide family-owned firms.

Practical implications
Practical implications emerge from the study findings. First, family owners should consider to hire a larger number of professional managers to support firms’ wealth maximization and retention and to reduce default risks. Second, investors should take into account the firms’ board of directors and management composition to better assess the investments risk level. Finally, the positive correlation between active family owners and systematic risk suggests the opportunity for regulators to improve the legal requirements related to minority directors to increase their effectiveness and, therefore, minority shareholders’ protection.

Originality/value
This study extends the literature on the association between ownership structure and firms’ risk levels, showing the effect of family managers on firms’ risk levels. Besides, to the best of the authors’ knowledge, no previous study investigates professional executives’ influence on risk when family ownership prevails.

Published: February 2022

PurposeThis study examines the effects of teacher-perpetrated sexual harassment on graduate students' academic and extracurricular performance using conservation of resources theory as a framework. Further, it looks into the moderating role of trait neuroticism on the indirect relationship between sexual harassment and student performance via emotional exhaustion.Design/methodology/approachLongitudinal data were collected in three waves from 218 Pakistani students over a period of three months during the fall 2019 semester. PROCESS Macro (v. 4) model 7 was used on SPSS (v. 21) to analyze the data for testing the moderated-mediation hypotheses.FindingsThe results show that as a source of toxic stress, teacher-perpetrated sexual harassment is negatively related to both academic performance and extracurricular performance, and that emotional exhaustion is a mediator in this inverse relationship. In addition, trait neuroticism strengthens the negative effect of teacher-to-student sexual harassment on student performance through emotional exhaustion.Originality/valueThis study addresses an unexplored moderated-mediation mechanism, and thus makes valuable contributions to education management research and practice. More specifically, it contributes by examining emotional exhaustion as a mediating variable in the relationship of teacher-perpetrated sexual harassment and student performance and, perhaps for the first time, establishes the moderating role of neuroticism in increasing the strength of the aforementioned relationship.
Does broader mean more general? Decomposing the effect of knowledge breadth on R&D and spillover of generic technology
Authors: Cen Jie , Wang Mian , Yang Yan , Li Jing , Yu Rongjian 
Published: February 2022

PurposeIn the context of collaborative research and development (R&D), multi-actor participation and multi-resource integration of technological knowledge has become the mainstream paradigm for the R&D and spillover of industry generic technology (GT). As GT's core characteristics, “fundamentality” and “externality,” make differential requests on knowledge bases regarding the R&D and spillover of GT (SGT). Knowledge breadth can enhance the generality of technology. The purpose of this paper is to integrate “generic technology R&D” and “generic technology spillover” into a single study, and try to solve the theoretical problem of “whether broader mean more general?”Design/methodology/approachThis paper collects and collates the patent data from the two patent databases of Derwent and SooPAT, and then makes an empirical analysis of the patent data collected by the authors with the data analysis software Stata.FindingsTaking 352 strategic emerging firms in China as the sample, this paper examined the effects of general knowledge breadth (GKB) and specific knowledge breadth (SKB) on the R&D and SGT. The authors concluded that both general and SKB have a positive effect on the R&D of GT (RGT), and the latter has a greater effect. There is a significant inverted U-shaped relationship between SKB and SGT.Originality/valueThe theoretical contributions of this paper are as follows. GT can effectively link different technologies and knowledge fields (Gambardella and Giarratana, 2013; Appioet al., 2017a, b). Therefore, existing studies regard the role of knowledge breadth on the R&D and SGT as an existing hypothesis. This paper challenges such hypothesis in two ways. First, this paper divides knowledge breadth into “general knowledge breadth” and “specific knowledge breadth” in response to the insufficient division of knowledge breadth in previous research, although some existing studies have examined the antecedents of the R&D and SGT from the perspective of R&D and SGT. Thus, the authors define GKB as the scope of context-free knowledge and SKB as the scope of context-specific knowledge, both of which shows differential nature, source and application. Second, this paper decomposes the effect of knowledge breadth on RGT, as well as on SGT, basing on distinguishing the SKB from GKB. Existing research reaches a consensus of the positive role of knowledge breadth, no matter on RGT or SGT (e.g. Schmidtet al., 2016; Appioet al., 2017a, b). Yet, such hypothesis ignores the refinement and decomposition of “knowledge breadth” in the research field of R&D and SGT, which is essential in promoting the development of GT theory. In this paper, the authors find that these two types of knowledge breadths play different roles in the RGT, and especially SKB plays a double-edged sword effect on the SGT.

Published: February 2022

PurposeShipping is a major source of air pollution, causing severe impacts on the environment and human health, greatly contributing to the creation of greenhouse gases and influencing climate change. The research was investigated to provide a better insight into the emission inventories in the Red River in Hanoi (Vietnam) that is often heavily occupied as the primary route for inner-city waterway traffic.Design/methodology/approachThe total emissions of seven different pollutants (PM10, PM2.5, SOx, CO, CO2, NOx and HC) were estimated using the SPD-GIZ emission calculation model.FindingsThe results show that CO2 has the most significant contribution to the gas volume emitted: 103.21 tons/day. Remarkably, bulk carriers are the largest emission vehicle, accounting for more than 97% of total emissions, due to their superior number and large capacity.Social implicationsThe result to have a roadmap for making efforts to fulfil its commitment so that it could achieve its net-zero climate target by 2050 in Vietnam as committed at COP26.Originality/valueIn this research, the number of vehicles and types of vessels travelling on the Red River flowing within Hanoi territory and other activity data are reported. The tally data will be used to estimate emissions of seven different pollutants (PM10, PM2.5, SOx, CO, CO2, NOx and HC) using a method combining both top-down and bottom-up approaches.
“We are praying from home”: reflections on the pandemic from resettled Rohingya refugees
Authors: Mitschke Diane B. , Laney Erin , Costello Emily , Faizal Mohamad 
Published: February 2022

Purpose
The effects of the COVID-19 pandemic were felt acutely by resettled refugee communities around the world. Adjusting to life in a new country typically presents a host of challenges that must be met by newly resettled refugees, and these challenges were no doubt compounded by the pandemic. The purpose of this study is to explore the lived experiences of resettled Rohingyan refugees living in the USA during the COVID-19 pandemic.

Design/methodology/approach
This study uses a grounded theory approach to derive meaning from qualitative interviews conducted with 21 Rohingyan refugees. This study embodied an emic design by involving the community in the development, conduction and interpretation of the data, rooting itself in the recognition of Rohingyan expertise and understanding.

Findings
The data yielded three major themes: financial instability, disruptions in access to health care and mental health distress. In addition, two minor themes were established: disruptions to everyday life and impacts on religious practices.

Originality/value
Little is known about the resettlement experiences of the Rohingyan people, who are arguably some of the most marginalized among refugees. With no written language shared among Rohingyans, communication barriers exacerbate an already challenging resettlement trajectory. The insights provided through this study are key to understanding the unique needs and strengths of Rohingyan refugees and will be valuable in shaping interventions to support their successful resettlement.

Authors: Davison H. Kristl , Braddy Phillip W. , Meriac John P. , Gigliotti Robert , Detwiler Daniel J. , Bing Mark N. 
Published: February 2022

PurposeWorkplace deviance remains a concern for many organizations, and narcissism has been identified as a primary contributor. The purpose of this paper is to investigate whether political skill and ambition interact with narcissism to attenuate or exacerbate workplace deviance.Design/methodology/approachThe authors surveyed a sample of 335 participants in leadership positions and empirically tested interactions among political skill, narcissism and ambition in predicting workplace deviance.FindingsThe authors performed moderated hierarchical regression analyses on the data to test the hypothesis and research question. Contrary to expectations, political skill attenuated the relationship between narcissism and workplace deviance. However, ambition was found to attenuate deviance, with the highest levels of deviance evident when narcissism was high, political skill was low, and ambition was also low.Originality/valueAlthough research has examined the relationship between narcissism and workplace deviance, to the authors’ knowledge, the study is the first to examine the roles of political skill and ambition in attenuating the manifestation of narcissism into workplace deviance.
When and how to use a “fighter brand” to combat a low-price entry
Authors: Deneffe Daniel , Vantrappen Herman 
Published: February 2022

Purpose
Managers have become wary of launching fighter brands. But they should not give up on a fighter brand strategy altogether: under certain conditions a fighter brand can be effective, if it is correctly positioned.

Design/methodology/approach
The authors’ decision-making framework to help managers think through the specific design of a fighter brand is supported by field experience in designing and successfully launching fighter brands. 10; The framework takes managers through four steps. 10;

Findings
A fighter brand can be designed to combat, and ideally eliminate, low-price competitors while protecting an organization’s premium-price offerings.

Practical implications
Identifying must-have features “must-haves” is at the core of the fighter brand framework.

Originality/value
If a company’s strategists can identify at least one unique must-have feature for the value segment with high certainty, and remove it from the fighter brand targeted at the price segment, the risk of cannibalization is minimal.
An analysis of post-pandemic scenarios and prospects for the shipping industry: perspective from Guadeloupe
Authors: Ferriera Mylène Rémi 
Published: February 2022

PurposeThe maritime port in Guadeloupe, a French island in the Lesser Antilles, is set to be transformed into a major logistics hub catering to the Greater Caribbean and the Lesser Antilles. The increase in shipping generated by expansion of the Panama Canal and the development of the cruise industry are the two main factors which contributed to the shift in the Island's policy that aims to capitalise on the increase in the expected shipping traffic in the region. This article examines various areas and policies which have been implemented so far by the Port of Guadeloupe and considers the innovative ways used to achieve its objectives and raises the question as to whether the Guadeloupian development in the logistics area is likely to be a force to be reckoned with in the Caribbean region.Design/methodology/approachThe approach employed involves the analysis of material extracted from published articles and information from periodic progress reports obtained from the Port of Guadeloupe.FindingsThe study showed that the Port of Guadeloupe had implemented various changes to achieve its objectives of becoming a major logistics hub in the region and “the smart port” of the Caribbean, which is likely to represent a challenge to Jamaica's aspiration to be the major port in the Caribbean.Research limitations/implicationsMuch of the published information accessed on the Guadeloupian Port and elsewhere is written in French, which could limit access to English speakers in conducting related research.Practical implicationsRapid logistic port development is taking place in the shipping arena in the French-speaking Caribbean and the Guadeloupian logistic hub's aim to be the number one “smart port” in the region could be realised sooner than expected.Social implicationsIf the Port of Guadeloupe achieves its objectives, it could impact on jobs in the shipping industry in the English-speaking Caribbean and affect people's standard of living.Originality/valueThe question as to whether the Port of Guadeloupe is a threat to other Caribbean ports has not yet been explored and the findings of this investigation would be useful to other port authorities.
