Modulation of tissue growth heterogeneity by responses to mechanical stress
Authors: Fruleux Antoine , Boudaoud Arezki 
Published: September 2018

AbstractMorphogenesis often yields organs with robust size and shapes, whereas cell growth and deformation feature significant spatio-temporal variability. Here, we investigate whether tissue responses to mechanical signals contribute to resolve this apparent paradox. We built a model of growing tissues made of fiber-like material, which may account for the cytoskeleton, polar cell-cell adhesion, or the extracellular matrix in animals, and for the cell wall in plants. We considered the synthesis and remodeling of this material, as well as the modulation of synthesis by isotropic and anisotropic response to mechanical stress. Formally, our model describes an expanding, mechanoresponsive, nematic, and active fluid. We show that mechanical responses buffer localized perturbations, with two possible regimes - hypo-responsive and hyper-responsive, and the transition between the two corresponds to a minimum value of the relaxation time. Whereas robustness of shapes suggests that growth fluctuations are confined to small scales, our model yields growth fluctuations that have long-range correlations. This indicates that growth fluctuations are a significant source of heterogeneity in development. Nevertheless, we find that mechanical responses may dampen such fluctuations, with a specific magnitude of anisotropic response that minimizes heterogeneity of tissue contours. We finally discuss how our predictions might apply to the development of plants and animals. Altogether, our results call for the systematic quantification of fluctuations in growing tissues.
Effect of power source mismatch on new venture performance
Authors: Wang Li , Jiang Marshall Shibing 
Published: September 2018

PurposeThe venture capital syndication brings in various resources for the portfolio firms, which positively affects those firms’ performance, while conflicts within syndicates also have negative impact on the portfolio firms’ performance. This study aims to explore the two opposite effects of the venture capital syndication on the portfolio firms’ operations. Drawing on Ma et al.’s (2013) power source match perspective, the authors examine the effect of (mis)match of power source between ownership and status on the portfolio firms’ performance.Design/methodology/approachThe study uses panel data from two professional databases containing information about the venture capital-backed firms in China. The fixed effect model is applied to analyze the data.FindingsThis study found that power source match in the venture capital syndicates works positively on the portfolio firms’ performance. This positive relationship is weakened when there is ownership-dominated power source mismatch present.Practical implicationsThis study suggests that when new ventures search for venture capital, it is better to allocate greater ownership to the venture capital providers with high-status power, so that ownership power and status power can have a proper match to increase the coordination among venture capital providers, thereby helping portfolio firms perform better.Originality/valueThis study looks into the performance of a portfolio firm when there is power a (mis)match in a venture capital syndication, extending the current literature in this area where only the performance of the venture syndications is examined.
Families and food: exploring food well-being in poverty
Authors: Voola Archana P. , Voola Ranjit , Wyllie Jessica , Carlson Jamie , Sridharan Srinivas 
Published: September 2018

Purpose This paper aims to investigate dynamics of food consumption practices among poor families in a developing country to advance the Food Well-being (FWB) in Poverty framework. Design/methodology/approach The research design used semi-structured interviews with 25 women and constructivist grounded theory to explore food consumption practices of poor families in rural South India. Findings Poor families’ everyday interactions with food reveal the relational production of masculinities and femininities and the power hegemony that fixes men and women into an unequal status quo. Findings provides critical insights into familial arrangements in absolute poverty that are detrimental to the task of achieving FWB. Research limitations/implications The explanatory potential of FWB in Poverty framework is limited to a gender (women) and a specific country context (India). Future research can contextualise the framework in other developing countries and different consumer segments. Practical implications The FWB in Poverty framework helps identify, challenge and transform cultural norms, social structures and gendered stereotypes that perpetuate power hegemonies in poverty. Policymakers can encourage men and boys to participate in family food work, as well as recognise and remunerate women and girls for their contribution to maintaining familial units. Originality/value This paper makes an original contribution to the relevant literature by identifying and addressing the absence of theoretical understanding of families, food consumption and poverty. By contextualising the FWB framework in absolute poverty, the paper generates novel understandings of fluidity and change in poor families and FWB.
A paradoxical dynamic in a service labyrinth: insights from HIV care
Authors: Cruz Angela Gracia B. , Snuggs Elizabeth , Tsarenko Yelena 
Published: September 2018

Purpose
While theories of complex service systems have advanced important insights about integrated care, less attention has been paid to social dynamics in systems with finite resources. This paper aims to uncover a paradoxical social dynamic undermining the objective of integrated care within an HIV care service system.

Design/methodology/approach
Grounded in a hermeneutic analysis of depth interviews with 26 people living with HIV/AIDS (PLWHA) and drawing on Bourdieu’s (1984) theory of capital consumption to unpack dynamics of power, struggle and contestation, the authors introduce the concept of the service labyrinth.

Findings
To competently navigate the service labyrinth of HIV care, consumers adopt capital consumption practices. Paradoxically, these practices enhance empowerment at the individual level but contribute to the fragmentation of the HIV care labyrinth at the system level, ultimately undermining integrated care.

Research limitations/implications
This study enhances understanding of integrated care in three ways. First, the metaphor of the service labyrinth can be used to better understand complex care-related service systems. Second, as consumers of care enact capital consumption practices, the authors demonstrate how they do not merely experience but actively shape the care system. Third, fragmentation is expectedly part of the human dynamics in complex service systems. Thus, the authors discuss its implications. Further research should investigate whether a similar paradox undermines integrated care in better resourced systems, acute care systems and systems embedded in other cultural contexts.

Originality/value
Contrasted to provider-centric views of service systems, this study explicates a customer-centric view from the perspective of heterosexual PLWHA.
Lean and Six Sigma in policing: austerity, driver or distraction?
Authors: Rodgers Bryan , Antony Jiju , Marshall Ivor 
Published: September 2018

Purpose
The purpose of this paper is to widen some of the recent discussion which focusses on austerity being the driver for introducing continuous improvement (CI) methodologies, such as Lean and Six Sigma, into policing.

Design/methodology/approach
The authors apply over 80 years combined experience in policing and CI to analyse academic and practitioner literature to summarise the drivers for change and the progress of Lean and Six Sigma in policing and the UK Public Sector.

Findings
The paper concludes that there are significant gaps in the literature and while there are undoubted challenges, there are overlaps between the strategic direction of policing and the approaches of Lean and Six Sigma.

Research limitations/implications
There are a small but growing number of papers which evidence the applicability of Lean and Six Sigma in policing.

Practical implications
The paper emphasises the risks to service delivery if factors such as budget constraints are considered in isolation. The paper provides examples of opportunities which may exist in policing as well as introducing ongoing work in policing.

Originality/value
This paper is among the first to explore the issues of how CI methodologies fit into the strategic direction and challenges of policing services.
The capital structure puzzle – evidence from Indian energy sector
Authors: Chakrabarti Anindita , Chakrabarti Ahindra 
Published: September 2018

Purpose
The purpose of this paper is to determine the factors affecting the capital structure of companies engaged in the Indian energy sector.

Design/methodology/approach
Capital structure theories and empirical literature have been reviewed to formulate propositions concerning the factors/variables determining the capital structure of Indian energy companies. The examination is done using panel data techniques for the sample 141 companies operating in the Indian energy sector.

Findings
The results show firms’ age, asset turnover ratio, liquidity and firms’ size to be significant determinants of capital structure for the Indian energy companies, while profitability, debt service capacity, sales growth, non-debt tax shield and tangibility ratio to be insignificant determinants. Historically, profitability has shared a significantly negative relationship with debt ratio; however, the relation here is not significant.

Research limitations/implications
The focus of the current study is on Indian energy sector, the results obtained will not be applicable for other sectors.

Originality/value
The current research gives an insight into the determinants of capital structure of the companies engaged in the Indian energy sector, which are mostly overlooked due to the laws, policies and regulations governing the sector as a whole.

Authors: Khan Muhammad Naveed , Akhtar Pervaiz , Merali Yasmin 
Published: September 2018

PurposeThe purpose of this paper is to investigate the knowledge gaps in the published research on terrorism-related risk in supply chains, and to develop a framework of strategies and effective decision-making to enable practitioners to address terrorism-related risks in supply chain risk management (SCRM) and security.Design/methodology/approachThe study adopts a novel combination of triangulated methods comprising a systematic literature review (SLR), text mining and network analysis. These methods have not been jointly utilized in past studies, and the approach constitutes a rigorous methodology that cross-validates results and ensures the reliability and validity of qualitative data.FindingsThe study reveals a number of key themes in the field of SCRM and security linked with terrorism. The authors identify relevant mitigation strategies and practices for effective strategic decision making. This subsequently leads us to develop a strategic framework of strategies and effective decision-making practices to address terrorism-related risk, affecting SCRM and security. The authors also identify key knowledge gaps in the literature and explore the main contributions by disciplines (e.g. business schools, engineering and maritime institutions) and countries.Practical implicationsThe authors provide a strategic framework of strategies and effective decision-making practices that managers can use to minimize terrorism-related risk in the context of SCRM and security.Originality/valueThis paper introduces a novel methodological combination for improving the quality of SLRs. It uses the approach to systematically review the strategies and effective decision-making practices interlinked with terrorism risk, affecting SCRM and security. It identifies significant knowledge gaps and defines directions for future research.
Integration in loosely coupled garment supply chains
Authors: Arroyo Pilar Ester , Holmen Elsebeth , De Boer Luitzen 
Published: September 2018

Purpose
This paper aims to deliberate about the problem of tight and seamless integration in a supply chain by conceptualising and understanding how looseness and its creation represent an effective supply chain design.

Design/methodology/approach
This research is grounded in system theory and industrial network research, while the case study of a textile and garment supply network coordinated by a third party in Mexico empirically illustrates how looseness in the supply chain may be created. The information gathered through in-depth interviews with critical informants at Aztex and three of their suppliers, visits in situ and secondary information, was organised with the template analysis technique and interpreted from three different but complementary perspectives, system theory, supply chain coordination modes and industrial networks, to establish the particularities of the triad model.

Findings
The study shows that supply chain integration may take place in a variety of forms, and that new theoretical perspectives are required to understand how the looseness in the connections among actors contributes to the flexibility and efficiency of the chain. Additionally, the analysis of the case puts forward the trader’s crucial role as linking pin between suppliers and customers in the specific context of the garment sector.

Research limitations/implications
Additional cases and triangulation of information from traders, suppliers and customers would contribute to explore in more detail how integration takes place not only in the textile and garment industry sector but also in other industries.

Practical implications
A rational explanation of why establish full integration across several tiers of suppliers and customers is too difficult to attain is given to managers. They may recognise that tight couplings will be necessary and possible only with strategic counterparts; meanwhile, others are more suitable to be delegated to a third party.

Social implications
The economic and industrial stability and progress of low-cost sourcing countries depends on the selection of international purchasers. The advancement of triangle manufacturing facilitated by a trader may become another criterion to drive the selection towards a region. In the case of Mexico, this adds to the near sourcing advantages of the country.

Originality/value
The research confirms that there is no unique global mode of supplier integration and suggests that different approaches are viable as long as the objectives of operational efficiency, good customer service and flexibility are satisfied.
Combating toxic workplace environment
Authors: Anjum Amna , Ming Xu 
Published: September 2018

Purpose
Across the globe, every organization is striving to enhance the productivity and growth rate, but the prosperity and success of an organization is determined by the type of work environment in which it operates. To address this apprehension, this paper aims to determine the effect of toxic workplace environment on job stress that can badly affect the job productivity of an employee.

Design/methodology/approach
As an independent variable, toxic workplace environment was used as a complete spectrum consisting multiple dimensions named as workplace ostracism, workplace incivility, workplace harassment and workplace bullying. Job stress was used as a mediating variable between the spectrum of toxic workplace environment and job productivity. In this regard, self-administered close-ended questionnaire was used to collect the data from 267 employees of the health sector (HS) of Lahore region in Pakistan. For analysis purpose, we used confirmatory factor analysis to ensure the convergent and discriminant validity of the factors. AMOS 22 was used to check the direct and indirect effect of selected variables. Hayes mediation approach was used to check the mediating role of job stress between four dimensions of toxic workplace environment and job productivity.

Findings
The output demonstrated that the dimensions of toxic workplace environment have a negative significant relationship with job productivity, while job stress was proved as a statistical significant mediator between dimensions of toxic workplace environment and job productivity. Finally, we conclude that organizations need to combat/cleanse the roots of toxic workplace environment to ensure their prosperity and success.

Originality/value
This study aims to determine the effect of toxic workplace environment on job stress that can badly affect the job productivity of an employee. An empirical study in the context of the HS of Pakistan. This study, which is based on HS, has never been reported before in literature.
Giving voice to the victims of sexual assault: the role of police leadership in organisational change
Authors: Rowe Michael , Macauley Michael 
Published: September 2018

Purpose
The purpose of this paper is to evaluate a long-term programme within a police service that sought to transform the policing of adult sexual assault cases through reforming case management and investigation practices, as well as cultural perspectives among staff.

Design/methodology/approach
The study is based on a case-study approach of change and reform within a single police service. Fieldwork consisted of more than 240 semi-structured interviews and focus groups with police officers, civilian staff, victim advocates, crown prosecutors, defence lawyers, doctors and staff from victim specialist support agencies. Extensive documentary analysis supplemented the primary findings.

Findings
Changes to investigations of sexual assault were perceived to be wide-ranging and deeply embedded, and were regarded positively by police officers, staff and external agencies. These are identified in terms of improvements to initial reporting of offences, the development of more rigorous case management and investigations, and enhanced relations with external support agencies.

Research limitations/implications
The study is necessarily limited to one case study and the analysis would be usefully developed through further application to other police services.

Social implications
The findings have considerable implications for police leaders and managers and wider society. Victim support and recovery agencies benefit from the reforms outlined, and there are considerable consequences for wider criminal justice that continues to disadvantage victims.

Originality/value
The paper has considerable originality since it offers a “deep” and “thick” understanding of reform within a particular context. The programme of reform was highly unusual since it was designed and delivered over a ten-year period and addressed many aspects of police organisation.
Equitable public library services for Canadians with print disabilities
Authors: Ciccone Michael 
Published: September 2018

Purpose
CELA, the Centre for Equitable Library Access, is a national not-for-profit organization whose mission is to support public libraries in providing accessible collections for Canadians with print disabilities and to champion the fundamental right of Canadians with print disabilities to access media and reading materials in the format of their choice. This paper aims to examine the history of the organization, the events that led to its creation, the issues with which it has and continues to struggle with – political, technological, structural – and the successes it has enjoyed.

Design/methodology/approach
This is a case study intended shine light on the development of a service sorely lacking in Canadian public libraries – consistent and sustainable publicly funded access to reading materials for Canadians with print disabilities – by providing related history and context and outlining current and future offerings.

Findings
The decision to centralize a service that most public libraries struggled to deliver within their own capacities was wise and has greatly benefited Canadians with print disabilities.

Originality/value
This paper provides a profile in determination, collaboration and the value of inclusivity in public libraries.
An accessibility-first approach to online course readers
Authors: Kwak Aneta , Newman Jeffrey 
Published: September 2018

Purpose
The purpose of this study was to develop a cost- and labor-efficient method for a small library to produce and deliver accessible course reading packages.

Design/methodology/approach
Working with approximately 25 courses and instructors in the Fall 2017 semester – including courses in Equity Studies and Disability Studies – the authors produced an inventory of assigned readings and an assessment of the accessibility of scanned texts that were currently being used. Based on this initial inventory, they developed new workflows for providing accessible readings to students that overcame the most common shortcomings and deficiencies.

Findings
This project established that it is possible for a small library to produce high-quality accessible course readings and that a PDF file is the most appropriate format for providing accessible scanned readings in an online course reader environment.

Practical implications
This project developed a workflow for producing texts that are designed from the perspective of universal access – that is, all students can engage with these texts without requiring the intervention of accessibility-services-style departments.

Originality/value
Canadian academic institutions are required to provide accessible texts upon request, a process which relies on students to identify required readings, sign up for specialized services and be comfortable disclosing and discussing their specialized needs. The process developed in this project builds upon a conception of equitable access as being a core principle and strives to create accessible readings as a default rather than as the result of an external request. This case study can be used as an example for institutions – especially small libraries – that are interested in developing a proactive approach to creating accessible readings and course packs.
Japan investment and Indonesia sustainability reporting: an isomorphism perspective
Authors: Fitriasari Dewi , Kawahara Naoko 
Published: September 2018

Purpose
The purpose of this study is to detect focal issues in sustainability reports in two different Asian countries based on the operating sustainability reporting law and regulations and to explore possible changes in laws and regulations because of investment interactions between the two countries.

Design/methodology/approach
This paper provides a descriptive literature review on laws and regulations related to sustainability reporting in Japan and Indonesia followed by an interpretive approach in the analysis.

Findings
Laws and regulations in Japan can lead to focus on the environmental aspect of sustainability. Laws and regulations in Indonesia can lead to variations in all aspects of sustainability reporting. All types of institutional isomorphism are possible investment system pressures.

Practical implications
This paper redefines issues in sustainability reporting based on the reporting environment created by laws and regulations in Japan and Indonesia.

Originality/value
This study assists researchers and investment analysts in understanding inherent reporting issues because of laws and regulations in both countries, and it expands existing theory for voluntary and mandatory reporting interaction studies.
