Authors: Ma Danfeng , Chen Yongqiang , Fu Yongcheng , Meng Chao 
Published: February 2022

PurposeThis study aims to first identify influencing factors of outsourcing decisions in construction projects systematically and further to unravel the interactions of these influencing factors from a holistic perspective.Design/methodology/approachThis study concerns the design and analysis of two-stage studies, where, at the first stage, a systematic literature review and 48 semi-structured interviews with senior practitioners in construction firms were conducted to identify influencing factors in outsourcing decisions in construction projects. At the second stage, the decision-making and trial evaluation laboratory (DEMATEL) method was employed to explore the interactions between influencing factors and pathways of outsourcing decisions.FindingsThree focuses for outsourcing decisions are outlined, revealing that outsourcing restrictions, strategic needs and cost objectives need to be considered in outsourcing decisions. In addition, the finding contributes to the integration of transaction costs perspective and capability perspective by unravelling the mechanism of how different factors work together.Practical implicationsThis study outlines 18 influencing factors and three sequential focuses for outsourcing decision-making, providing a clearer understanding of each factor’s contribution for decision-makers.Originality/valueMost of the existing studies stressed the net effect of individual outsourcing factors from a single logic and paid little attention to their complex causal relationship. This study develops a holistic perspective of the influencing factors of outsourcing in construction projects by contending the overall knowledge of outsourcing and analyzing the causal relationship between them.
The dark side of projectification: a systematic literature review and research agenda on the negative aspects of project work and their consequences for individual project workers
Authors: Aguilar Velasco Maria Magdalena , Wald Andreas 
Published: February 2022

PurposeProject work usually has a positive connotation and is considered innovative and modern. However, many project workers suffer from chronic stress, work overload and burnout. This study aims to integrate the determinants of the negative aspects of project work and their implications for individuals involved in projects.Design/methodology/approachA systematic review was used to analyze 290 papers from various disciplines to identify the most used theories, determinants of the negative aspects of project work and the consequences of these aspects for project participants' work-related and overall well-being.FindingsBased on the findings of the review, this paper develops a multi-level framework that includes determinants at the levels of society, organizations, projects and individuals and discusses opportunities for further research. The findings show that socio-psychological theories and occupational health theories are the dominant theories used in research. The most frequently studied individual outcomes are affective symptoms and work-related outcomes. Detrimental individual outcomes are mostly associated with psychosocial work factors.Originality/valueThe study contributes to the literature by providing a comprehensive review of research on the negative aspects of project work and their implications for project workers. The multi-level framework can serve as a guide for future research and provides important insights for practitioners.
Resisting pulling the plug: the role of CEO regulatory focus and board independence in store closure activity
Authors: Iglesias Jose Luis Castro 
Published: February 2022

Purpose
Although being fired up about changes such as firm expansion, chief executive officers (CEOs) have a hard time with changes that involve divesting businesses or downsizing operations. This study aims to examine how a particular psychological process – regulatory focus – serves as a managerial exit barrier in the context of store closings in the US retail industry. This study also examines how a particular corporate governance mechanism, the board of directors, moderates the relationship between CEO regulatory focus and divestment activity.

Design/methodology/approach
This study content-analyzed letters to shareholders to measure the regulatory focus of retail CEOs and used negative binomial regression to test the effect of the CEO’s regulatory focus and board independence on store closure activity.

Findings
The two motivation orientations – promotion and prevention – focuses have distinct effects on store closure decisions. As predicted, promotion-focused CEOs, who value attainment and growth, resist “pulling the plug.” Conversely, prevention-focused CEOs, who are more sensitive to losses, are more inclined to close stores. Independent boards decrease the CEOs’ resistance to “pull the plug” only when necessary, which is the case when CEOs have less vigilant tendencies.

Research limitations/implications
This study contributes to the strategy and marketing literature. It examines an individual-level antecedent of store closure decisions and responds to the call for research on the effect of regulatory focus on divestment decisions.

Practical implications
Leaders themselves can be a source of resistance to change. The findings suggest the importance of boards hiring CEOs psychologically aligned with the firms’ strategic priorities. Promotion-focused CEOs may be a better fit for companies engaged in growth and acquisition. By contrast, prevention-focused CEOs may be a better fit for firms involved in retrenchment and restructuring. Independent boards still have the power to influence CEO decisions in the case of a misfit, as the findings suggest.

Originality/value
This study examines divestment decisions during the “retail apocalypse” and provides empirical evidence for the existence of managerial exit barriers, first introduced by Michael Porter.
Wear behaviors at different temperatures of ZrO2 reinforced A356 matrix composites produced by mechanical alloying method
Authors: Şimşek Doğan , Özyürek Dursun , Salman Serdar 
Published: February 2022

Purpose
The purpose of this study, the tribological behaviors at different temperatures of aluminium matrix composites (AMCs) with different amounts of ZrO2 added were investigated.

Design/methodology/approach
Aluminium graphite (A356/2 wt% graphite (solid lubricant)) composite powders prepared by adding four different amounts (3 wt%, 6 wt%, 9 wt% and 12 wt%) of Zirconia (ZrO2) to the matrix were mechanically alloyed for 4 h. Wear tests were conducted at five different temperatures (20 °C, 100 °C, 180 °C, 260 °C and 340 °C) and for three different sliding distances (53 m, 72 m and 94 m) on the pin-on-disc type wear tester.

Findings
Results of the study showed that the highest hardness and density value were measured for 12% ZrO2 added AMC material. Wear test results showed that weight loss increases with increasing temperature; weight loss decreases at all temperatures with the increasing amount of reinforcement in the matrix.

Originality/value
In this paper, the tribological properties of aluminium matrix composites produced by the mechanical alloying method by adding different amounts of ZrO2 were determined by simulating the tribological properties at different loads and temperatures.
Comparing outsourcing-outlook of manufacturing firms and logistics service providers in India and DACH countries
Authors: Maditati Dhanavanth Reddy , Kummer Sebastian , Munim Ziaul Haque , Schramm Hans-Joachim 
Published: February 2022

Purpose
According to the logistics performance index, emerging countries such as India are lagging behind developed countries such as Germany, Austria and Switzerland (DACH region). The purpose of this study is to compare and understand the differences in logistics outsourcing outlook in the two regions by considering both manufacturing firms (M-firms) and logistics service providers’ (LSPs) perspectives.

Design/methodology/approach
A survey targeting both LSPs and M-firms in DACH and India is conducted. A total of 96 responses were analyzed by using the chi-square test to investigate the differences and alignments in outsourcing motivation, relationship and governance between firms within and across regions.

Findings
M-firms in India bear strategic motivations behind outsourcing and those in DACH incline towards costs. LSPs in both regions align with the motivations of M-firms. M-firms in India rely more on LSPs by transferring the ownership of outsourced tasks, as compared to DACH. Both M-firms and LSPs in DACH claim a high level of ownership. However, firms in DACH and India do not differ significantly in terms of outsourcing engagements they seek.

Research limitations/implications
The findings may only be generalized to large firms in India and DACH.

Practical implications
The findings of this study help managers enhance their understanding of the differences between M-firms and LSPs, and also across countries. LSPs in DACH, if they wish to operate successfully in India, will have to adapt to the M-firms strategic motivations and offer higher dependency.

Originality/value
This study is novel, as it investigates differences between India and DACH countries while also including both manufacturers’ and logistics service providers’ perspectives.
Pro-environmental behaviours of management students in times of the COVID-19 pandemic
Authors: Bugdol Marek , Szklarczyk Dariusz 
Published: February 2022

PurposeThe main objective of the conducted research was to find out various manifestations of pro-environmental behaviours (PEBs) amongst students of extramural programmes forced to stay at home during the lockdown period.Design/methodology/approachIn order to identify manifestations of PEBs during the lockdown, the authors conducted research with the participation of students of various management extramural programmes in a Polish university. The primary research method was diary, supplemented by literature review and analysis of curriculum content.FindingsPro-sanitary behaviours that dominated during the pandemic period were aimed at protecting individuals from contracting the virus and resulted from legal regulations. No clear and regular differences in PEBs were observed amongst the respondents with respect to their age, gender or familiarity with management systems used in their respective workplaces. Student-employees acquire little knowledge of PEBs during their studies. A serious barrier to the development of PEBs is the lack of access to knowledge that would clearly indicate the causes of environmental degradation.Practical implicationsBased on the obtained results, a list of recommendations for educational practices was developed. The list emphasises the importance of drawing students' attention to PEBs in the household environment.Originality/valueThe conducted research was another project focussed in general on environmental behaviours and aimed in particular at exploring how mandatory social distancing influenced people's PEBs. The paper also highlights some limitations of the diary method used to identify people's behaviours in the pandemic context.
Herbivory may mediate the effects of nutrients on the dominance of alien plants
Authors: Li Yanjun , Gao Yingzhi , van Kleunen Mark , Liu Yanjie 
Published: February 2022

Abstract

Numerous studies have highlighted the roles of nutrient availability and fluctuations therein for invasion success of alien plants. Many others also highlighted the role of herbivores in invasion success. However, how herbivory and the level and fluctuations in nutrient availability interact in driving alien plant invasion into native communities remains largely unexplored.

We grew eight invasive alien species as target species in pot‐mesocosms with five different synthetic native communities in a three‐factorial design with two levels of nutrient availability (low vs. high), two levels of nutrient fluctuation (constant vs. pulsed) and two levels of above‐ground insect herbivory (with vs. without herbivores). As natural communities have both specialist and generalist herbivores, we simulated this using both a generalist and a specialist herbivorous grasshopper.

The relative biomass production of the alien target plants to the total biomass production (i.e. alien biomass/total biomass) decreased in response to an increase in nutrient availability, but increased in response to the presence of herbivores. Furthermore, we found indications that the dominance of the alien target species may depend on interactions of herbivory with changes in nutrient availability and nutrient fluctuations, although these interactions were only marginally significant.

Our multi‐trophic multi‐species experiment suggests that herbivory could mediate the interactive effect of nutrient enrichment and variability in nutrient supply on invasion of alien plants into native communities. Therefore, we recommend that studies testing the effects of resources on plant invasion should also consider interactive effects of other trophic levels.

HR analytics: An emerging field finding its place in the world alongside simmering ethical challenges
Authors: Edwards Martin R. , Charlwood Andy , Guenole Nigel , Marler Janet 
Published: February 2022

AbstractHR analytics is an emerging field attracting substantial practitioner and academic attention. This article introduces the special issue on HR Aanalytics for the HRMJ. Several recent reviews in the area have struggled to find HR analytics research in the published literature and a key aim of this special issue is to show case high quality analytic projects and cutting‐edge analytic techniques to contribute to this emerging subfield of HRM. Before considering the papers in the special issue, we reflect on two key challenges in the area: First, HR analytics is not a recognized keyword, this makes it difficult to categorise and identify HR analytics research in the field. Second, there are a growing number of reviews of a field that has a limited range of recognised examples of empirical papers to draw on. We discuss the difficulties and potential political sensitivities for practitioners seeking to publish ‘within firm’ HR analytics projects. We also consider the growing recognition that organisations engaging in HR analytics projects have a range of ethical challenges to deal with going forward.

Published: February 2022

AbstractBelowground herbivores are overseen and underestimated, even though they can cause significant economic losses in agriculture. The cabbage root fly Delia radicum (Anthomyiidae) is a common pest in Brassica species, including agriculturally important crops, such as oilseed rape. The damage is caused by the larvae, which feed specifically on the taproots of Brassica plants until they pupate. The adults are aboveground‐living generalists feeding on pollen and nectar. Female flies are attracted by chemical cues in Brassica plants for oviposition. An assembled and annotated genome can elucidate which genetic mechanisms underlie the adaptation of D. radicum to its host plants and their specific chemical defences, in particular isothiocyanates. Therefore, we assembled, annotated and analysed the D. radicum genome using a combination of different next‐generation sequencing and bioinformatic approaches. We assembled a chromosome‐level D. radicum genome using PacBio and Hi‐C Illumina sequence data. Combining Canu and 3D‐DNA genome assembler, we constructed a 1.3 Gbp genome with an N50 of 242 Mbp and 6 pseudo‐chromosomes. To annotate the assembled D. radicum genome, we combined homology‐, transcriptome‐ and ab initio‐prediction approaches. In total, we annotated 13,618 genes that were predicted by at least two approaches. We analysed egg, larval, pupal and adult transcriptomes in relation to life‐stage specific molecular functions. This high‐quality annotated genome of D. radicum is a first step to understanding the genetic mechanisms underlying host plant adaptation. As such, it will be an important resource to find novel and sustainable approaches to reduce crop losses to these pests.
The risk of intrauterine exposure to SARS‐CoV‐2 in female COVID‐19 patients: A comprehensive review

Published: February 2022

AbstractSevere acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) is a new type of coronavirus that has caused fatal infectious diseases and global spread. This novel coronavirus attacks target cells through the interaction of spike protein and angiotensin‐converting enzyme II (ACE2), leading to different clinical symptoms. However, for a successful pregnancy, a well‐established in‐uterine environment includes a specific immune environment, and multi‐interactions between specific cell types are prerequisites. The immune‐related changes in patients infected with novel coronavirus could interfere with the immune microenvironment in the uterus, leading to fetal loss. We first reviewed the intrauterine environment in the normal development process and the possible pregnancy outcome in the infection state. Then, we summarized the immune response induced by SARS‐CoV‐2 in patients and analyzed the changes in ACE2 expression in the female reproductive system. Finally, the present observational evidence of infection in pregnant women was also reviewed.

Published: February 2022

AbstractBackgroundPatients with hypertrophic cardiomyopathy (HCM) in sinus rhythm commonly show the fourth heart sound (S4). The lack of S4 may be a marker of impaired atrial function in HCM patients with sinus rhythm.Methods and ResultsThis retrospective study consisted of 47 patients with HCM who had undergone phonocardiography and a cardiopulmonary exercise test. The primary outcome was a composite of cardiac death, stroke, hospitalization for worsening heart failure, and newly developed atrial fibrillation (AF). S4 was detected in 38 of 43 patients with sinus rhythm (88%). Peak oxygen consumption was the highest in 38 sinus rhythm patients with S4 (23.6 ± 5.6 mL/kg/min), middle in five sinus rhythm patients without S4 (19.3 ± 6.7 mL/kg/min), and lowest in four patients with AF (15.7 ± 3.3 mL/kg/min, p = 0.01). After a median of 40.5 months, the incidence of the primary outcome was higher in patients without S4 than in those with S4 (33% vs. 8%; hazard ratio, 6.17; 95% confidence interval, 1.02 – 37.4; p = .04) and higher in sinus rhythm patients without S4 than in those with S4 (60% vs. 8%; hazard ratio, 12.05; 95% confidence interval, 2.31 – 71.41; p = .007).ConclusionsThe absence of S4 on phonocardiography was associated with impaired exercise tolerance and adverse cardiac events in HCM patients with sinus rhythm.
Prolonged ST segment and T‐wave alternans with torsade de pointes secondary to hypocalcemia due to hypoparathyroidism: A case report
Authors: Liu Jiang , Hou Hong , Xu Hui , Chen Yazhuo , Su Xiaoling 
Published: February 2022

AbstractHypoparathyroidism predisposes patients to hypocalcemia. Patients with hypoparathyroidism are thus at risk of electrocardiographic abnormalities, including T‐wave alternans. T‐wave alternans is poorly understood and lacks uniform diagnostic criteria. Its presence suggests myocardial electrical instability, and it has become an important sign for identifying patients at high risk of malignant arrhythmias and sudden cardiac death. We report a rare case of T‐wave alternans with torsade de pointes due to hypocalcemia. The etiology of T‐wave alternans may easily be overlooked. It should thus be thoroughly investigated to avoid misdiagnosis and poor outcomes.
Spying on the prior of the number of data clusters and the partition distribution in Bayesian cluster analysis
Authors: Greve Jan , Grün Bettina , Malsiner‐Walli Gertraud , Frühwirth‐Schnatter Sylvia 
Published: February 2022

SummaryCluster analysis aims at partitioning data into groups or clusters. In applications, it is common to deal with problems where the number of clusters is unknown. Bayesian mixture models employed in such applications usually specify a flexible prior that takes into account the uncertainty with respect to the number of clusters. However, a major empirical challenge involving the use of these models is in the characterisation of the induced prior on the partitions. This work introduces an approach to compute descriptive statistics of the prior on the partitions for three selected Bayesian mixture models developed in the areas of Bayesian finite mixtures and Bayesian nonparametrics. The proposed methodology involves computationally efficient enumeration of the prior on the number of clusters in‐sample (termed as ‘data clusters’) and determining the first two prior moments of symmetric additive statistics characterising the partitions. The accompanying reference implementation is made available in the R package fipp. Finally, we illustrate the proposed methodology through comparisons and also discuss the implications for prior elicitation in applications.
Better support for national than local system during the COVID‐19 pandemic in China

Published: February 2022

AbstractIndividuals increase their support for social systems in response to the threat, panic, and uncertainty that characterized the COVID‐19 pandemic. This could be because a powerful social system can compensate for a lack of control at the individual level. However, the levels of public support for national versus local systems could be different in China. Two studies investigate whether people support the national more strongly than the local system during the COVID‐19 pandemic. Study 1 analyzed data of 3593 participants from China; the results showed that participants reported higher levels of support for the national system than the local. In Study 2, we further tested a possible moderator for it. With a sample of 275 participants, we found that the difference between public support for national and local systems in China was based on the perceived higher response efficacy with the national government. Implications for research on system justification and governmental pandemic responses were discussed.
Estimated Quadratic Inference Function for Correlated Failure Time Data
Authors: Yan Feifei , Liu Yanyan , Cai Jianwen , Zhou Haibo 
Published: February 2022

AbstractAn estimated quadratic inference function method is proposed for correlated failure time data with auxiliary covariates. The proposed method makes efficient use of the auxiliary information for the incomplete exposure covariates and preserves the property of the quadratic inference function method that requires the covariates to be completely observed. It can improve the estimation efficiency and easily deal with the situation when the cluster size is large. The proposed estimator which minimizes the estimated quadratic inference function is shown to be consistent and asymptotically normal. A chi-squared test based on the estimated quadratic inference function is proposed to test hypotheses about the regression parameters. The small-sample performance of the proposed method is investigated through extensive simulation studies. The proposed method is then applied to analyze the Study of Left Ventricular Dysfunction (SOLVD) data as an illustration.
