PRC1-dependent compaction of Hox gene clusters prevents transcriptional derepression during early Drosophila embryogenesis
Authors: Cheutin Thierry , Cavalli Giacomo 
Published: January 2018

Summary paragraphPolycomb-group (PcG) proteins are conserved chromatin factors that maintain the silencing of key developmental genes, notably the Hox gene clusters, outside of their expression domains [1-3]. Polycomb repressive complex 2 (PRC2) trimethylates lysine K27 of histone H3 [4], and PRC1 collaborates with PRC2 in gene silencing. Genome-wide studies have revealed large H3K27me3 chromatin domains bound by PcG proteins, and Polycomb domains fold into distinct nuclear structures [5-9]. Although PRC1 is involved in chromatin compaction [10-16], it is unknown whether PRC1-dependent transcriptional silencing is a consequence of its role on higher-order chromatin folding. This is because depletion of PRC1 proteins typically induces both chromatin unfolding and ectopic transcription, and ectopic transcription can open chromatin by itself. To disentangle these two components, we analysed the temporal effects of two PRC1 proteins, Polyhomeotic (Ph) and Polycomb (Pc), on Hox gene clusters during Drosophila embryogenesis. We show that the absence of Ph or Pc affects the higher-order chromatin folding of Hox clusters prior to ectopic Hox gene transcription, demonstrating that PRC1 primary function during early embryogenesis is to compact its target chromatin. During later embryogenesis, we observed further chromatin opening at Hox complexes in both Ph and Pc mutants, which was coupled to strong deregulation of Hox genes at this stage of development. Moreover, the differential effects of Ph and Pc on Hox cluster folding matches the differences in ectopic Hox gene expression observed in these two mutants, suggesting that the degree of Hox derepression in PcG mutants depends on the degree of structural constraints imposed by each PcG component. In summary, our data demonstrate that binding of PRC1 to large genomic domains during early embryogenesis induces the formation of compact chromatin to prevent ectopic gene expression at later time-points. Thus, epigenetic mechanisms such as Polycomb mediated silencing act by folding chromatin domains and impose an architectural layer to gene regulation.

Published: January 2018

Purpose
This paper aims to present a new numerical model for geometric nonlinear analysis of thin-shell structures based on a combined finite-discrete element method (FDEM).

Design/methodology/approach
The model uses rotation-free, three-node triangular finite elements with exact formulation for large rotations, large displacements in conjunction with small strains.

Findings
The presented numerical results related to behaviour of arbitrary shaped thin shell structures under large rotations and large displacement are in a good agreement with reference solutions.

Originality/value
This paper presents new computationally efficient numerical model for geometric nonlinear analysis and prediction of the behaviour of thin-shell structures based on combined FDEM. The model is implemented into the open source FDEM package “Yfdem”, and is tested on simple benchmark problems.
A self-adaptive bat algorithm for the truck and trailer routing problem
Authors: Wang Chao , Zhou Shengchuan , Gao Yang , Liu Chao 
Published: January 2018

Purpose
The purpose of this paper is to provide an effective solution method for the truck and trailer routing problem (TTRP) which is one of the important NP-hard combinatorial optimization problems owing to its multiple real-world applications. It is a generalization of the famous vehicle routing problem (VRP), involving a group of geographically scattered customers served by the vehicle fleet including trucks and trailers.

Design/methodology/approach
The meta-heuristic solution approach based on bat algorithm (BA) in which a local search procedure performed by five different neighborhood structures is developed. Moreover, a self-adaptive (SA) tuning strategy to preserve the swarm diversity is implemented. The effectiveness of the proposed SA-BA is investigated by an experiment conducted on 21 benchmark problems that are well known in the literature.

Findings
Computational results indicate that the proposed SA-BA algorithm is computationally efficient through comparison with other existing algorithms found from the literature according to solution quality. As for the actual computational time, the SA-BA algorithm outperforms others. However, the scaled computational time of the SA-BA algorithm underperforms the other algorithms.

Originality/value
In this work the authors show that the proposed SA-BA is effective as a method for the TTRP problem. To the authors’ knowledge, the BA has not been applied previously, as in this work, to solve the TTRP problem.
Entrepreneurship education, gender and family background as antecedents on the entrepreneurial orientation of university students
Authors: Marques Carla S.E. , Santos Gina , Galvão Anderson , Mascarenhas Carla , Justino Elsa 
Published: January 2018

Purpose
This study aims to evaluate the impact of entrepreneurship education (EE) on the entrepreneurial orientation (EO) of higher education students, as mediated by gender and family history. A survey tool for measuring EO was developed and used in one university. The responses were processed using statistical methods.

Design/methodology/approach
The data were collected with an online questionnaire distributed to students of engineering and business and social sciences in the past year of their degree program at the undergraduate and graduate levels. Some respondents had a class in entrepreneurship, while others did not have it.

Findings
The results highlight that EE generally has a greater impact on business and social sciences students. Family background and gender are moderating variables with a positive influence on individual entrepreneurial orientation (IEO).

Practical implications
This study’s main practical implication is that evidence was found that universities need to develop more effective didactic approaches to EE. These must take into account new market demands and students’ profile and always taking into account their different academic areas and levels of previous EE.

Originality/value
This paper contributes to filling a gap in the literature by identifying the importance of EE, gender and family background to the development of IEO in students of different academic programs (i.e. engineering, business and social sciences).
A revisit of lean production on performance based on heterogeneity
Authors: Zhu Xuechang , Lin Yu 
Published: January 2018

Purpose
The purpose of this paper is to revisit causal effects and investigate hysteresis effects of lean production on performance. With a focus on firm heterogeneity, this paper explores the role of organization ownership structure in shaping the relationship between lean production and performance.

Design/methodology/approach
The propensity score matching (PSM) model combined with difference-in-difference (DID) estimation is applied to minimize selection bias caused by firm heterogeneity and endogeneity problems derived from unobserved fixed variables that could potentially affect the desired causal relationship.

Findings
Results show that lean production has no significant effect on business performance; however, the relationship between lean production and operations performance is positive and significant, especially for non-state-owned firms. Furthermore, the non-significant effect of lean production on performance of state-owned firms is largely due to the failure of lean production implementation. Meanwhile, lean production can only improve operations performance of non-state-owned firms in the short term due to their inability to continuously implement lean production.

Research limitations/implications
This paper only covers manufacturing listed firms in China. Further studies are needed to test the wide implications of this paper in other countries.

Practical implications
This paper may help managers to identify problems in the implementation of lean production for different organization ownership structure firms, thus providing new insight into the implementation of lean production.

Originality/value
This paper appears to be the first one to examine causal effects of lean production on performance in China by applying the PSM model combined with DID estimation.
Public sector undertakings: Bharat’s other Ratnas
Authors: Chhibber Ajay , Gupta Swati 
Published: January 2018

Purpose
While national public policies such as performance contracts and disinvestment affect the dynamics of large- and medium-scale state-owned enterprises in emerging market economies, the purpose of this paper is to analyze the performance of India’s public sector undertakings (PSUs) and suggest options to improve their outcomes.

Design/methodology/approach
Using firm-level data on India’s 235 PSUs with total assets of around $500 billion over the past two and half decades (1990-2015), the study empirically tests the effect of performance contracts, measured by memorandum of understanding (MOU) and disinvestment, measured by private equity share, on PSUs performance indicator such as return on capital (ROC). Data were collected from the Public Enterprises Survey Reports released by the Department of Public Enterprises under India’s Ministry of Heavy Industries and Public Enterprises, Department of Disinvestment, Bombay Stock Exchange and Capitaline database. By controlling firm-, industry- and macro-level factors in regression models, the results were presented in several aspects like service sector, non-service sector and individual and joint effects.

Findings
Empirical estimations indicate that performance contracts such as MOUs have had a positive impact on PSU performance by increasing their ROC by 8-9 percent. This result holds more strongly for the non-service sector (manufacturing, mining) but less so for service sector firms. In the case of service sector firms, partial privatization (share sales) has a significant impact on performance, making them ideal candidates for more aggressive disinvestment. Larger PSUs (Maharatnas) appear to perform better than smaller PSUs and even better than private firms of similar size. Smaller PSUs (Navratnas and Miniratnas) perform worse than private companies and should be good candidates for strategic disinvestment (privatization). PSUs that do not have Ratna status – and are loss makers – should be disposed of their asset value.

Practical implications
The study recommends that India should change the public sector balance sheet by raising capital through strategic disinvestment (privatization), disinvestment and liquidation of PSUs and re-investing it, in public infrastructure through the National Infrastructure Investment Fund and not into the budget as a revenue-raising measure. It should also transform Maharatnas into world class companies with greater commercialization.

Originality/value
The paper makes significant contributions to the academic literature on the changing dynamics of state-owned enterprises in emerging economies by examining the effect of performance contracts and disinvestment on India’s PSUs performance. It is one of unique longitudinal-empirical studies on India’s PSU performance in several dimensions.
From welfare to wealth creation
Authors: Gakhar Divya Verma , Phukon Abhijit 
Published: January 2018

PurposeThe purpose of this paper is to review several influential empirical studies that examine the performance of state-owned enterprises (SOEs). The paper undertakes a citation analysis of journals, authors and titles in the area of privatization and firm performance in general, and assesses the impact of privatization on the performance of SOEs in particular.Design/methodology/approachThe methodology is based on a systematic and structured review of over 100 papers published in economics, public management, business strategy and related social sciences. The systematic review is based on citation analysis of journals, authors and titles. The journal and author citation counts were tabulated by leveraging the databases of SCImago Journal Rankings and Google Scholar and filtered it to find out the most highly cited journals and authors. The structured review is based on the framing opinion with respect to major findings, variables selected, measurement techniques and statistical tools applied by different researchers. The impact is measured through coding a value “P” in case of positive effects, “N” in case of negative effects and “NT” in case the study found both positive and negative effects.FindingsThe citation analysis reveals thatAmerican Economic Review,Journal of Financial Economics,Review of Financial StudiesandJournal of Financeas the top-cited journals, and Megginson and Netter (3,468), Megginsonet al.(1,737), Djankov and Murrell (1,356), Boardman and Vining (1,320), Balsamet al.(1,094) and DeWenter and Malatesta (1,018) as the top-cited authors in this particular research field. While majority research studies have revealed a significant improvement in the performance of SOEs in the post-privatization period, few studies have reserved their impact as neutral or even negative in some respects.Originality/valueGiven that economic transitions, corporate governance, and performance of SOEs have attracted a great attention from public management and business strategy scholars in recent years, this paper aims to summarize a large number of empirical studies that examine the performance of SOEs. The paper would be useful to future researchers especially the beginners and early career researchers in terms of its current trends, selection of variables, measurement techniques and statistical tools applied.
Data governance activities: a comparison between scientific and practice-oriented literature
Authors: Alhassan Ibrahim , Sammon David , Daly Mary 
Published: January 2018

Purpose
The purpose of this paper is to explore the current literature on data governance in scientific and practice-oriented publications, and to provide a comparative analysis of the activities reported for data governance. Data have become a key organisational asset and data governance both a necessary and critical activity.

Design/methodology/approach
A comprehensive literature review is conducted in order to identify the published material that reflects the current state of knowledge. A systematic procedure was followed that identified 61 publications that explicitly mention data governance activities. Open coding techniques were applied to conduct content analysis, resulting in the identification of 591 concepts. A critical analysis also identified gaps in the literature.

Findings
The analysis identified 120 data governance activities which are understood as: “action” plus “area of governance” plus “decision domain” (e.g. define data policies for data quality). The authors define and present a data governance activities model based on the analysis. The analysis also shows a higher volume of data governance activities reported by practice-oriented publications that are associated with the “implement” and “monitor” actions of the areas of governance across the decision domains compared with scientific publications, whereas The authors found that the scientific publications focus more on defining activities. The results contribute to identifying research gaps and concerns on which ongoing and future research efforts can be focused.

Research limitations/implications
This paper is of interest to both academics and practitioners, as it helps them understand the activities associated with a data governance programme. Current literature fails to provide a comprehensive understanding of the data governance activities that are required when considering a data governance programme. Therefore, the proposed model for data governance activities can be used to give insights into these activities.

Originality/value
To the knowledge of the authors, this study is the first to explicitly consider data governance activities from both an academic and practice-oriented perspective.

Authors: Tayyem Reema , Allehdan Sabika , Bawadi Hiba , Tuuri Georgianna , Al-Mannai Mariam , Musaiger Abdulrahman Obaid 
Published: January 2018

PurposeThe purpose of this study is to evaluate the associations between adolescents’ perceptions of their parents’ and peers’ opinions about body weight and their actual weight status.Design/methodology/approachA total of 795 Jordanian adolescents, 15-18 years of age, were recruited in this study. Adolescents completed a questionnaire to evaluate their perceptions: about how their parents’ and peers’ viewed their weight, regarding any criticism of their parents and peers about their weight and if their parents compared their weight against their siblings.FindingsThe study found that the majority of non-overweight adolescents thought their parents and peers considered them to have a normal weight (94.9 and 94.6 per cent for boys, 76.6 and 85.5 per cent for girls, respectively). For obese girls, 83.4 per cent thought their parents and 91.7 per cent thought their peers perceived them as overweight. The risk of being obese was significantly related to the amount of parental criticism perceived by adolescent girls with OR = 3.9 (95 per cent CI: 1.6-9.4;P= 0.01), while perception of peer criticism showed an increased trend of risk for obesity in boys. Adolescents’ perceptions regarding parental comparisons between their body weights against their siblings’ body weight was found to increase the risk for obesity significantly among girls.Originality/valueThe current study highlights that most of the obese adolescents perceived that their parents and peers underestimated their actual weight status. While obese boys were more likely to report being criticized about their body shape by their peers, obese girls indicated that they received more criticism about their weight from their parents.
The associations between environmental disclosures with financial performance, environmental performance, and firm value
Authors: Deswanto Refandi Budi , Siregar Sylvia Veronica 
Published: January 2018

Purpose
This study aims to investigate both the direct and indirect associations of environmental disclosures with financial performance, environmental performance and firm value.

Design/methodology/approach
The samples are companies listed on the Indonesia Stock Exchange in the agriculture industry, mining industry, basic industry and chemicals, miscellaneous industry and consumer goods industry and that are participating in the Performance Rating Assessment Program on Environment Management (PROPER/Program Penilaian Peringkat Kinerja Perusahaan) of the Ministry of the Environment Republic of Indonesia or have been awarded the Green Industry Award by the Ministry of Industry Republic of Indonesia in 2012-2014. Data are collected from sustainability reports, annual reports and annual financial statements. The authors used simultaneous equation modeling and panel data regression analysis to analyze the data.

Findings
The authors find that the financial performance does not affect the environmental disclosures. The lagged environmental performance has a positive effect on the current environmental disclosures, and environmental disclosures do not affect the firm market value and do not mediate the effect of financial performance and environmental performance on firm value.

Originality/value
This study comprehensively examines both direct and indirect associations of environmental disclosures with financial performance, environmental performance and firm value, which is rarely examined in extant studies.
Trust and distrust in society and public perception of CSR: a cross-cultural study
Authors: Rim Hyejoon , Dong Chuqing 
Published: January 2018

Purpose
The purpose of this study is to investigate cross-cultural perspectives of corporate social responsibility (CSR) based on Carroll’s (1979, 1991) hierarchical CSR model. The present study examines the role of government and business trust in shaping publics’ expectations of business responsibility.

Design/methodology/approach
The primary data were derived from a cross-sectional survey in the USA, UAE and South Korea (N = 1,121). This paper compares publics’ prioritizations of business responsibilities across countries and examines how public trust in the government and business is related to CSR perceptions.

Findings
The paper presents evidence that publics’ perception of CSR differs significantly across the countries. Moreover, in a trusting society like the UAE, publics tend to put more emphasis on economic and philanthropic duties for business, whereas in a distrusting society like South Korea, publics consider legal and ethical responsibility to be important.

Originality/value
This study adds to the current understanding of diverse publics’ perception of CSR across culture and societies by highlighting the role of public trust in government in defining CSR.
The influence of corporate governance practices on corporate social responsibility reporting
Authors: Rashid Afzalur 
Published: January 2018

PurposeThis study aims to investigate if “corporate governance practices” have any influence on firm corporate social responsibility (CSR) reporting by listed firms in Bangladesh.Design/methodology/approachThis study uses a content analysis to examine specific corporate social responsibility (CSR)-related attributes from 101 publicly listed non-financial firms in Bangladesh. Using various attributes of social and environmental reporting, a disclosure index is also constructed.FindingsThe finding of this study is that corporate governance practices do not have any influence on firm CSR reporting. The findings, in particular, show that CSR disclosure by firms is not responsive to new corporate governance regulations.Research limitations/implicationsThis study is subject to some limitations, such as the subjectivity or judgement associated in the coding process.Practical implicationsThe implication of this study is that firm CSR practices are legitimization exercises and firms will not make increased disclosure due to regulator’s quest for institutionalisation of corporate governance practices.Originality/valueThis study contributes to the literature on the practices of CSR reporting in the context of developing countries following regulator’s quest for institutionalisation of corporate governance practices.
