AbstractMotor neurons (MNs) control muscle movement and are essential for breathing, walking and fine motor skills. Motor Neuron and Pancreas Homeobox 1 (MNX1) has long been recognized as a key marker of the MN lineage. Deficiency of the Mnx1 gene in mice results in early postnatal lethality – likely by causing abnormal MN development and respiratory malfunction. However, the genome-wide targets and exact regulatory function of Mnx1 in MNs remains unresolved. Using an in vitro model for efficient MN induction from mouse embryonic stem cells, we identified about six thousand MNX1-bound loci, of which half are conserved enhancers co-bound by the core MN-inducing factors ISL1 and LHX3, while the other half are promoters for housekeeping-like genes. Despite its widespread binding, disruption of Mnx1 affects the activity of only a few dozen MNX1-bound loci, and causes mis-regulation of about one hundred genes, the majority of which are up-regulated pan-neuronal genes with relatively higher expression in the brain compared to MNs. Integration of genome-wide binding, transcriptomic and epigenomic data in the wild-type and Mnx1-disrupted MNs predicts that Pbx3 and Pou6f2 are two putative direct targets of MNX1, and both are homeobox transcription factors highly expressed in the central nervous system. Our results suggest that MNX1 is crucial for restraining the expression of many pan-neuronal genes in MNs, likely in an indirect fashion. Further, the rarity of direct targets in contrast to the widespread binding of MNX1 reflects a distinctive mode of transcriptional regulation by homeobox transcriptional factors.
The factors influencing Saudi Arabian women's persistence in nontraditional work careers
Authors: Dukhaykh Suad , Bilimoria Diana 
Published: August 2021

PurposeThe purpose of this study is to explore the factors that influence Saudi Arabian women to persist in nontraditional work careers, which are primarily in gender-integrated work environments and male-dominated industries.Design/methodology/approachQualitative research was conducted based on semistructured interviews with 30 Saudi women – 18 of whom were working in nontraditional careers and 12 of whom had worked in nontraditional careers but subsequently left to pursue more traditional, female-associated career opportunities. Interview data were recorded, transcribed and analyzed using grounded theory methods.FindingsDistinct similarities and differences between the two subsamples emerged from the data. Similarities between the two groups included men's underestimation of women's performance, lack of access to workplace sites and resources, male colleagues' cultural fears of violating gender norms and social rejection of women in the workplace. Women who persisted in nontraditional work careers articulated a high level of self-efficacy, an optimistic future vision, positive relationships with male colleagues and family support, which enabled them to persevere despite numerous difficulties associated with working in a male-dominated environment. A conceptual model is developed that integrates the findings explaining Saudi women's persistence in nontraditional work careers.Research limitations/implicationsSelf-reported data and a small sample size are the main limitations of this study.Practical implicationsMale managers of women in nontraditional work settings are encouraged to engage positively with women professionals in their teams and to provide opportunities for growth and development for all members of the workforce. Saudi public policy decision-makers, families, educators and organizations interested in retaining and increasing female workforce participation should take into account the factors influencing Saudi women's persistence in nontraditional work careers.Originality/valueAlthough some studies in Western contexts have addressed the factors that influence the persistence of women in nontraditional careers, less work has been done in the Middle East and North Africa (MENA) sociocultural context. Specifically, in the present study, the authors investigate the factors that influence women's persistence in nontraditional careers in Saudi Arabia's high gender-role-oriented culture.
Knowledge sharing in the construction supply chain: collaborative innovation activities and BIM application on innovation performance
Authors: Shi Qiao , Wang Qiankun , Guo Zeng 
Published: August 2021

PurposeThis paper aimed to examine the role of knowledge sharing among member enterprises between collaborative innovation activities and innovation performance and between building information modeling (BIM) application and innovation performance in the construction supply chain.Design/methodology/approachThe structural equation model was used in this study. First, the hypothesis of the relationship between collaborative innovation activities, BIM application, knowledge sharing and innovation performance in the construction supply chain was proposed based on experience; then, the research data were collected by investigation; finally, this hypothesis was tested through data analysis.Findings(1) Collaborative innovation activities in the construction supply chain had a positive impact on explicit knowledge sharing, tacit knowledge sharing and innovation performance. (2) BIM application had a positive impact on explicit knowledge sharing and innovation performance, while it had no significant impact on tacit knowledge sharing. (3) Explicit knowledge sharing had no positive effect on innovation performance, while tacit knowledge sharing had positive effect on organizational performance. (4) Tacit knowledge sharing produced partial mediating effect between collaborative innovation activities, BIM application and innovation performance, while explicit knowledge sharing produced complete mediating effect between BIM application and tacit knowledge sharing.Originality/valueA relationship model among collaborative innovation activities, BIM application, explicit and tacit knowledge sharing and innovation performance in the construction supply chain was proposed, and the rationality of the model was verified by empirical analysis. Discovering the relationships between these factors can be not only conducive to mastering the effect of explicit and tacit knowledge sharing in the collaborative innovation process of construction supply chain, but also play a guiding role for the function development of BIM.

Research on clothing patterns generation based on multi-scales self-attention improved generative adversarial network
Authors: Yu Zi-yan , Luo Tian-jian 
Published: August 2021

PurposeClothing patterns play a dominant role in costume design and have become an important link in the perception of costume art. Conventional clothing patterns design relies on experienced designers. Although the quality of clothing patterns is very high on conventional design, the input time and output amount ratio is relative low for conventional design. In order to break through the bottleneck of conventional clothing patterns design, this paper proposes a novel way based on generative adversarial network (GAN) model for automatic clothing patterns generation, which not only reduces the dependence of experienced designer, but also improve the input-output ratio.Design/methodology/approachIn view of the fact that clothing patterns have high requirements for global artistic perception and local texture details, this paper improves the conventional GAN model from two aspects: a multi-scales discriminators strategy is introduced to deal with the local texture details; and the self-attention mechanism is introduced to improve the global artistic perception. Therefore, the improved GAN called multi-scales self-attention improved generative adversarial network (MS-SA-GAN) model, which is used for high resolution clothing patterns generation.FindingsTo verify the feasibility and effectiveness of the proposed MS-SA-GAN model, a crawler is designed to acquire standard clothing patterns dataset from Baidu pictures, and a comparative experiment is conducted on our designed clothing patterns dataset. In experiments, we have adjusted different parameters of the proposed MS-SA-GAN model, and compared the global artistic perception and local texture details of the generated clothing patterns.Originality/valueExperimental results have shown that the clothing patterns generated by the proposed MS-SA-GAN model are superior to the conventional algorithms in some local texture detail indexes. In addition, a group of clothing design professionals is invited to evaluate the global artistic perception through a valence-arousal scale. The scale results have shown that the proposed MS-SA-GAN model achieves a better global art perception.
The effect of presenteeism among Bangladeshi employees
Authors: Haque Amlan 
Published: August 2021

PurposePresenteeism refers to attending work while ill and not being able to work to full capacity. Applying the social cognitive theory (SCT), this paper examines the relationships among presenteeism, job satisfaction (JS), and employee turnover intentions (ETIs), and the mediational influence of JS on the relationship between presenteeism and ETIs.Design/methodology/approachA web-based survey, including a pilot test, was administered to collect data targeting a sample of 200 full-time Bangladeshi employees. With a two-step method of the structural equation modelling technique, this paper examines four hypotheses among the variables of presenteeism, JS and ETIs.FindingsSignificant negative relationships were identified between presenteeism and JS, as well as between JS and ETIs. Further investigations showed a significant positive relationship between presenteeism and ETIs. Notably, presenteeism on ETIs was found to be fully mediated by JS.Practical implicationsThe study results suggest that presenteeism can be detrimental to both JS and ETIs among Bangladeshi employees; however, a reduction in rates of presenteeism can be achieved if employees' JS is valued and increased. Both the theoretical and managerial implications, including future research opportunities, are discussed.Originality/valueFollowing the SCT, this paper extends the knowledge of presenteeism in a non-Western context. It is also a first reported empirical study among Bangladeshi employees demonstrating the influence of presenteeism and its detrimental effects on employees' motivational behaviour. This study makes a unique contribution to the presenteeism literature by examining JS and ETIs from the perspective of SCT.

Published: August 2021

PurposeWorkplace mindfulness training has many benefits, but designing programs to reach a wide audience effectively and efficiently remains a challenge. The purpose of this study is to assess the effects of a widely adopted workplace mindfulness program on the mindfulness, active listening skill, emotional intelligence, and burnout of employees in a large, multinational internet company.Design/methodology/approachThe study sample included 123 employees across three company offices who completed the two‐day Search Inside Yourself (SIY) program. Data were collected using self‐report measures pre‐, post‐, and four‐weeks post‐intervention and were analyzed using paired samples t-tests.FindingsSignificant increases were detected in mindfulness and the “awareness of emotion” components of emotional intelligence four weeks post-course. No significant changes were found in participants' self-reported levels of burnout, active listening skill or the “management of emotion” components of emotional intelligence.Practical implicationsTeaching workplace mindfulness and emotional intelligence skills through a highly applied, condensed course format may be effective for increasing mindfulness and the “awareness” components of emotional intelligence. Longer courses with more applied practice may be necessary to help participants build emotional management and listening skills and to reduce burnout.Originality/valueThe present study is, to the authors’ knowledge, the first academic, peer-reviewed assessment of SIY, a workplace mindfulness training program that has been taught to over 50,000 people worldwide.
Long run apartment price dynamics in Swedish and German cities
Authors: Engerstam Sviatlana 
Published: August 2021

PurposeThis study examines the long term effects of macroeconomic fundamentals on apartment price dynamics in major metropolitan areas in Sweden and Germany.Design/methodology/approachThe main approach is panel cointegration analysis that allows to overcome certain data restrictions such as spatial heterogeneity, cross-sectional dependence, and non-stationary, but cointegrated data. The Swedish dataset includes three cities over a period of 23 years, while the German dataset includes seven cities for 29 years. Analysis of apartment price dynamics include population, disposable income, mortgage interest rate, and apartment stock as underlying macroeconomic variables in the model.FindingsThe empirical results indicate that apartment prices react more strongly on changes in fundamental factors in major Swedish cities than in German ones despite quite similar development of these macroeconomic variables in the long run in both countries. On one hand, overreactions in apartment price dynamics might be considered as the evidence of the price bubble building in Sweden. On the other hand, these two countries differ in institutional arrangements of the housing markets, and these differences might contribute to the size of apartment price elasticities from changes in fundamentals. These arrangements include various banking sector policies, such as mortgage financing and valuation approaches, as well as different government regulations of the housing market as, for example, rent control.Originality/valueIn distinction to the previous studies carried out on Swedish and German data for single-family houses, this study focuses on the apartment segment of the market and examines apartment price elasticities from a long term perspective. In addition, the results from this study highlight the differences between the two countries at the city level in an integrated long run equilibrium framework.

Published: August 2021

PurposeThe purpose of this study is to diagnose the trajectory of influential conceptual articles in developing a research stream. The authors uncover the knowledge diffusion through influential conceptual articles and identify characteristics that make conceptual articles influential in their field.Design/methodology/approachThis study draws on scientometrics, specifically an integrated approach combining quantitative citation counts with qualitative citation practices analysis that offers a comprehensive understanding of the nature and context of citations. The authors use the case of customer engagement – a prominent contemporary marketing and service research stream – to explore the trajectory of influential articles in shaping a new research stream.FindingsThis research shows that influential articles contribute to the reciprocal knowledge diffusion within and outside their home discipline. They provide anchor points for conceptual framing, conceptual refining and conceptual reconciliation – three application patterns of citations that are pivotal to navigate theory discovery and theory justification in a research field.Research limitations/implicationsThe study analyzes the early impact period of two influential customer engagement articles to understand the developments leading to the establishment of a new research stream. Future research drawing on automated citation and bibliometric methods may consider extended time periods.Originality/valueThis study traces the trajectory of influential articles in marketing and service research. The authors identify characteristics of influential conceptual articles, and recommend practices to develop a conceptual paper with the potential for an influential trajectory. It shows that while marketing and service research has a tradition of “borrowing” theories from other fields, seminal articles “lend” theories to other fields.
The challenges facing the next Chief Executive of Hong Kong in 2022: managing growth, conflict, change and continuity
Authors: Ip Lau Regina Suk-yee 
Published: August 2021

PurposeThis article outlines the challenges faced by the next Chief Executive of the Hong Kong Special Administrative Region (HKSAR) in 2022 – the need to address economic problems resulting from Hong Kong’s slow growth; its inability to restructure its economy to broaden job opportunities and improve upward mobility for young people; and the government’s belated attempt to deploy innovation and technology.Design/methodology/approachThis article is based on the author’s in-depth analysis of the current situation and insights on the challenges faced by the next Chief Executive.FindingsTensions are inherent in the concept of “One Country, Two Systems”. Back in November 2012, Deputy Director of the Hong Kong and Macao Office Zhang Xiaoming already reminded Hong Kong of the need to manage well three sets of relationships: (1) maintaining the “One Country” principle while preserving the SARs’ “separate systems”; (2) upholding Central Authority while preserving the SARs’ “high degree of autonomy”; and (3) unleashing the economic potential of mainland China while raising the competitiveness of the SARs. These three sets of relationships represent three fundamental difficulties in implementing “One Country, Two Systems”. However, Hong Kong kept ignoring Beijing’s advice and failed to resolve the tension between the mainland and Hong Kong SAR, culminating in the riotous events of 2019, which morphed into a dangerous, anti-China insurgency.Originality/valueThe next Chief Executive needs to mediate between the constitutional requirements of the Central Authority while preserving Hong Kong SAR’s “high degree of autonomy”, its unique character and lifestyle. He or she also needs to deal with continuity and change. Hong Kong cannot stand still, and should not allow itself to be lulled by the “50 years no change” mantra into overlooking the need to move with the times. Much reform needs to be implemented by the next Chief Executive to give people hope, faith in “One Country, Two Systems” and true love of the country.
The role of shade in maintaining alternative stable states between open‐ and closed‐canopy vegetation

Published: August 2021

Abstract

Fire is commonly identified as strong driver of alternative stable states such as adjacent open‐ versus closed‐canopy vegetation types. The absence of open‐canopy species from closed‐canopy understoreys, where light availability is low and dynamic, however, suggests shade tolerance is an integral determinant of such vegetation boundaries. While the importance of light dynamics between alternative stable states has been acknowledged, the physiological mechanisms behind sun versus shade tolerance are unclear. Here we investigated the differences in light interception and carbon assimilation of open‐ and closed‐canopy species, and whether this contributes to the maintenance of alternative stable states.

Evergreen forest and fynbos species were grown under three light availability treatments (24%, 54% and 100%) in a glasshouse with their photosynthetic response to continuous and fluctuating light, dark respiration, root respiration, biomass and leaf traits quantified.

Fynbos species displayed smaller, thicker and tightly aggregated leaves compared to forest species. Under low light, fynbos species experienced some mortality, and showed lower light‐use efficiency with fluctuating light and lower in situ photosynthetic rates under the 54% light treatment compared to forest species (0.8 vs. 3.4 μmol CO2 m−2 s−1).

Synthesis. Contrasting light availability in forest and fynbos selects for dissimilar traits, where fynbos species are unable to efficiently intercept light and maintain a positive carbon balance under low, dynamic light compared to forest species. This shade intolerance is exacerbated by divergent nutrient and fire regimes in forest and fynbos environments, requiring incompatible trait specialisations that promote the emergence and maintenance of alternative stable states.
On the diachronic origins of the accentual contrast in Terena (Arawakan)
Authors: Orphão de Carvalho Fernando 
Published: August 2021

AbstractThis paper presents internal and comparative evidence showing that the origin of the accentual contrast of modern Terena, an Arawakan language of southwestern Brazil, is related to a diachronic process of word‐initial vowel loss. Alternations internal to the language involve a relation between vowel‐initial trisyllabic allomorphs and consonant‐initial disyllabic allomorphs, the latter bearing a tonal accent. Comparative evidence from Mojeño, one of Terena’s closest relatives, provides crucial support for the correspondence between word‐initial vowels and an initial tonal accent. A coherent account is proposed, tracing both the loss of initial syllables and the emergence of an accentual contrast to sub‐phonemic patterns enforcing durational unevenness in iambic feet: syllables in foot‐internal, non‐head position were lost, while the previously allophonic lengthening of the head syllable was phonologized, yielding the tonally marked accent.
