Authors: Liu Lin , Wang Guangyu , Wang Liguo , Yu Chunlei , Li Mengwei , Song Shuhui , Hao Lili , Ma Lina , Zhang Zhang
Published: October 2019

Glioma is one of the most common malignant brain tumors and exhibits low resection rate and high recurrence risk. Although a large number of glioma studies powered by high-throughput sequencing technologies have led to massive multi-omics datasets, there lacks of comprehensive integration of glioma datasets for uncovering candidate biomarker genes. In this study, we collected a large-scale assemble of multi-omics multi-cohort datasets from worldwide public resources, involving a total of 16,939 samples across 19 independent studies. Through comprehensive multi-omics molecular profiling across different datasets, we revealed thatPRKCG(Protein Kinase C Gamma), a brain-specific gene detectable in cerebrospinal fluid, is closely associated with glioma. Specifically, it presents lower expression and higher methylation in glioma samples compared with normal samples.PRKCGexpression/methylation change from high to low is indicative of glioma progression from low-grade to high-grade and high RNA expression is suggestive of good survival. Importantly,PRKCGin combination withMGMTis effective to predict survival outcomes after TMZ chemotherapy in a more precise manner. Collectively,PRKCGbears the great potential for glioma diagnosis, prognosis and therapy, andPRKCG-like genes may represent a set of important genes associated with different molecular mechanisms in glioma tumorigenesis. Accordingly, our study indicates the importance of computational integrative multi-omics data analysis and represents a data-driven scheme toward precision tumor subtyping and accurate personalized healthcare.

Author Summary

Glioma is a type of brain tumors that represents one of the most lethal human malignancies with little chance for recovery. Nowadays, more and more studies have adopted high-throughput sequencing technologies to decode the molecular profiles of glioma from different omics levels, accordingly resulting in massive glioma datasets generated from different projects and laboratories throughout the world. Therefore, it has become crucially important on how to make full use of these valuable datasets for computational identification of glioma candidate biomarker genes in aid of precision tumor subtyping and accurate personalized treatment. In this study, we comprehensively integrated glioma datasets from all over the world and performed multi-omics molecular data mining. We revealed thatPRKCG, a brain-specific gene abundantly expressed in cerebrospinal fluid, bears the great potential for glioma diagnosis, prognosis and treatment prediction, which has been consistently observed on multiple independent datasets. In the era of big data, our study highlights the significance of computational integrative data mining toward precision medicine in cancer research.
Cell surface mechanics gate stem cell differentiation
Authors: Bergert Martin , Lembo Sergio , Milovanović Danica , Börmel Mandy , Neveu Pierre , Diz-Muñoz Alba
Published: October 2019

Cell differentiation typically occurs with concomitant shape transitions to enable specialized functions. To adopt a different shape, cells need to change the mechanical properties of their surface. However, whether conversely cell surface mechanics control the process of differentiation has been relatively unexplored. Here, we show that membrane mechanics gate the exit from naïve pluripotency of mouse embryonic stem cells. By measuring membrane tension during differentiation, we find that naïve stem cells release their plasma membrane from the underlying actin cortex when transitioning to a primed state. By mechanically tethering the plasma membrane to the cortex with a synthetic signalling-inert linker, we demonstrate that preventing this detachment forces stem cells to retain their naïve pluripotent state. We thus identify a decrease in membrane-to-cortex attachment as a new cell-intrinsic mechanism that is essential for stem cells to exit pluripotency.
Membrane tension mediated mechanotransduction drives fate choice in embryonic stem cells
Authors: De Belly Henry , Jones Philip H. , Paluch Ewa K. , Chalut Kevin J.
Published: October 2019

Changes in cell shape and mechanics frequently accompany cell fate transitions. Yet how mechanics affects the regulatory path-ways controlling cell fate is poorly understood. To probe the interplay between shape, mechanics and fate, we used embryonic stem (ES) cells, which spread as they undergo early differentiation. We found that this spreading is regulated by a beta-catenin mediated decrease in plasma membrane tension. Strikingly, preventing the membrane tension decrease obstructs early differentiation of ES cells. We further find that blocking the decrease in membrane tension inhibits endocytosis of FGF signalling components, which direct the exit from the ES cell state. The early differentiation defects we observed can be rescued by increasing Rab5a-facilitated endocytosis. Thus, we show that a mechanically-triggered increase in endocytosis regulates fate transitions. Our findings are of fundamental importance for understanding how cell mechanics regulates biochemical signaling, and therefore cell fate.

Environmental sustainability of facilities management
Authors: Jayasena Nimesha Sahani , Mallawaarachchi Harshini , De Silva Lalith
Published: October 2019

Purpose

Rapid changes in the environment escalate the requirement of environmental sustainability assessment within built environment. The purpose of this paper is to model the environmental sustainability of facilities management (FM) functions in apparel industry in Sri Lanka.

Design/methodology/approach

A comprehensive literature review was carried out in order to identify the importance of sustainability assessment for FM, sustainable FM functions and their environmental sustainability indicators. Subsequently, a questionnaire survey was carried out to determine a relative weight of the sustainable FM functions and environmental sustainability indicators through the analytical hierarchy process analysis.

Findings

Energy management was identified as the most significant FM function in terms of environmental sustainability in apparel industry with a relative performance of 49.12 per cent. Subsequently, the functions of water management (29.39 per cent), maintenance management (11.98 per cent) and waste management (9.64 per cent) obtained the second, third and fourth ranks while asset management (7.85 per cent) was the function which had the least performance score. Relative weights for the environmental sustainability indicators were also determined.

Research limitations/implications

In respect of the apparel industry, the developed model can be utilised for assessing the environmental sustainability of FM in broader term.

Originality/value

No proper mechanism was found to assess the sustainability of FM in apparel sector since very fewer research studies were focussed on achieving environmental sustainability in different industries. Hence, the assessment of environmental sustainability of FM in apparel industry is an emerging necessity in the present day, which was addressed in this research.

Authors: Malviya Rakesh Kumar , Kant Ravi
Published: October 2019

Purpose

The purpose of this paper is to explore green supply chain management (GSCM) performance measures and to develop a framework for evaluating the impact of GSCM implementation on organizational performance.

Design/methodology/approach

This research develops a performance measurement framework by integrating GSCM enabler with GSCM performance measures criteria. These criteria are selected from literature review and expert opinion. This study proposes a fuzzy balanced scorecard – fuzzy technique for order preference by similarity to ideal solution-based methodology to evaluate the overall organizational performance. The empirical case study of an Indian automobile organization is conducted. Further, the proposed framework is tested with three Indian Automobile organizations and their results are compared with the case organization.

Findings

The integrated methodology offers an effective way to measure and benchmark the impact of the proposed GSCM performance measurement framework. The empirical results show that the output of the proposed model is consistent. Thus, the study contributes to the advancement of knowledge toward GSCM and its management for sustainability.

Research limitations/implications

This study is limited to the automotive sector; hence the outcomes may not be comprehensively applicable across different sectors. The results cannot be applied to other sectors with other product and process specificities.

Practical implications

It helps the practitioners to measure and improve the effectiveness of GSCM implementation.

Originality/value

This study is the generalized performance measurement framework and can be used to measure the performance for any type of organizations to benchmark one organization with the other or the group of organizations.
C2O and Frontyard: hacking the archives to design community spaces in Surabaya and Sydney
Authors: Bacon Luke , Azali Kathleen , Crosby Alexandra Lara , Forster Benjamin
Published: October 2019

Purpose

The purpose of this study is to identify shared themes and concerns of two local and critical archives by comparing their design and day-to-day practice.

Design/methodology/approach

The action research has drawn on the experience of collaboration between a Sydney-based community space (Frontyard) and the Surabaya-based co-working community (C2O) over one year. Each space houses a small physical library of books, which is the focus of this analysis.

Findings

Hacking has emerged as a key value of both archives. A hacking approach has shaped the design of each space and the organisation each archive. Hacking frames the analysis of each collection in this study.

Practical implications

Pragmatic and political understanding of such archives have implications for better quality and more authentic exchange between the communities that make use of these libraries in Indonesia and Australia.

Originality/value

While some work on local critical archives has been done in Indonesia and Australia, no research to date has made specific comparisons with the aim of sharing knowledge. Because these archives are often temporary and ephemeral, documenting the work that goes into them, and their practitioners’ perspectives, is urgent, making possible shared knowledge that can inform the ways communities make decisions about their own heritage.
Recovery-based error estimator for the natural-convection problem based on penalized finite element method
Authors: Li Lulu , Su Haiyan , Zhao Jianping , Feng Xinlong
Published: October 2019

Purpose

This paper aims to proposes and analyzes a novel recovery-based posteriori error estimator for the stationary natural-convection problem based on penalized finite element method.

Design/methodology/approach

The optimal error estimates of the penalty FEM are established by using the lower-order finite element pair P1-P0-P1 which does not satisfy the discrete inf-sup condition. Besides, a new recovery type posteriori estimator in view of the gradient recovery and superconvergent theory to deal with the discontinuity of the gradient of numerical solution.

Findings

The stability, accuracy and efficiency of the proposed method are confirmed by several numerical investigations.

Originality/value

The provided reliability and efficiency analysis is shown that the true error can be effectively bounded by the recovery-based error estimator.
Explorations of employee-based brand equity in the banking industry from a perceived-leadership perspective
Authors: Lee Yi-Hsuan , Hsiao Chan , Chan Hsin-Yi , Lee I-Chen
Published: October 2019

Purpose

The purpose of this paper is to answer the question of how brand-specific transformational leadership (TFL) and transactional leadership (TRL) enhance employee-based brand equity (EBBE) by influencing employees’ perceived brand value congruence (EPBVC).

Design/methodology/approach

This study employed hierarchical linear modeling and chose moderating variables that are primarily related to the working environment: person–job fit (PJF) and person–group fit (PGF). The sample included managers and employees of the largest domestic bank in Taiwan.

Findings

Questionnaires were distributed to banking staff in the service industry. The results imply that both brand-specific TFL and brand-specific TRL require the mediation of PJF and PGF to influence EBBE, which then influences brand equity. Without these mediators, brand-specific TFL and brand-specific TRL have no effects on EBBE.

Originality/value

Compared to the results from other studies, these results imply a unique discovery that both brand-specific TFL and brand-specific TRL require the mediation of PJF and PGF to influence EPBVC, which in turn influences EBBE. Without these mediators, brand-specific TFL and brand-specific TRL do not have any effects.
The evolution of female entrepreneurship in the Gulf Cooperation Council, the case of Bahrain
Authors: Alexandre Laurice , Kharabsheh Radwan
Published: October 2019

Purpose

Bahrain is a member of the Gulf Cooperation Council (GCC). It is the third smallest country in Asia. Like its neighbours’, Bahrain’s economy is developing fast and the place of women in the work landscape is evolving. But few papers discuss the situation of women entrepreneurs in this country. The purpose of this paper is to study the evolution of women entrepreneurship in Bahrain, a country in the midst of high transition. The research question is: How do Bahraini women cope with the evolution of their environment? And how far are they keen to develop their own businesses?

Design/methodology/approach

After a literature review, a qualitative research was conducted among 12 women entrepreneurs of 19 to 51 years of age.

Findings

The results show a new kind of female entrepreneurship in the Arab region based on the support of the sociocultural environment, which is in contradiction with the literature. Also, it seems that Bahrain women are more in pull, not push situation to entrepreneurship. However, they need a role model to achieve their goals, which is new to the literature about women entrepreneurship in general and that in the developing countries in particular. As regards the obstacles, some Bahraini women seem to suffer from a lack of experience and knowledge in setting a business online. However, the results show that the companies of these women are mostly small and evolving in the service sector, with a trend in online businesses.

Research limitations/implications

This study is limited by the number of persons interviewed, which does not allow the generalization of the results. Also, generalization to the whole region is not possible because each country of the GCC has its own rules and practices towards women. Also, this study has not investigated the attitude towards the risk and the balance between family and profession.

Originality/value

This paper is one of the few research studies on female entrepreneurship in Bahrain. The findings are in contradiction with the literature on women entrepreneurship in developing countries and more specifically in the GCC. This study offers many research perspectives and could help governmental and non-governmental institutions to empower and support women in their actions.
Crypto-currencies narrated on tweets: a sentiment analysis approach
Authors: Rouhani Saeed , Abedin Ehsan
Published: October 2019

Purpose

Crypto-currencies, decentralized electronic currencies systems, denote a radical change in financial exchange and economy environment. Consequently, it would be attractive for designers and policy-makers in this area to make out what social media users think about them on Twitter. The purpose of this study is to investigate the social opinions about different kinds of crypto-currencies and tune the best-customized classification technique to categorize the tweets based on sentiments.

Design/methodology/approach

This paper utilized a lexicon-based approach for analyzing the reviews on a wide range of crypto-currencies over Twitter data to measure positive, negative or neutral sentiments; in addition, the end result of sentiments played a training role to train a supervised technique, which can predict the sentiment loading of tweets about the main crypto-currencies.

Findings

The findings further prove that more than 50 per cent of people have positive beliefs about crypto-currencies. Furthermore, this paper confirms that marketers can predict the sentiment of tweets about these crypto-currencies with high accuracy if they use appropriate classification techniques like support vector machine (SVM).

Practical implications

Considering the growing interest in crypto-currencies (Bitcoin, Cardano, Ethereum, Litcoin and Ripple), the findings of this paper have a remarkable value for enterprises in the financial area to obtain the promised benefits of social media analysis at work. In addition, this paper helps crypto-currencies vendors analyze public opinion in social media platforms. In this sense, the current paper strengthens our understanding of what happens in social media for crypto-currencies.

Originality/value

For managers and decision-makers, this paper suggests that the news and campaign for their crypto in Twitter would affect people’s perspectives in a good manner. Because of this fact, the firms, investing in these crypto-currencies, could apply the social media as a magnifier for their promotional activities. The findings steer the market managers to see social media as a predictor tool, which can analyze the market through understanding the opinions of users of Twitter.
Blockchain-driven customer order management
Authors: Martinez Veronica , Zhao Michael , Blujdea Ciprian , Han Xia , Neely Andy , Albores Pavel
Published: October 2019

Purpose

The purpose of this paper is to investigate the effects of Blockchain on the customer order management process and operations. There is limited understanding of the use and benefits of Blockchain on supply chains, and less so at processes level. To date, there is no research on the effects of Blockchain in the customer order management process.

Design/methodology/approach

A twofold method is followed. First, a Blockchain is programmed and implemented in a large international firm. Second, a series of simulations are built based on three scenarios: current with no-Blockchain, 1-year and 5-year Blockchain use.

Findings

Blockchain improves the efficiency of the process: it reduces the number of operations, reduces the average time of orders in the system, reduces workload, shows traceability of orders and improves visibility to various supply chain participants.

Research limitations/implications

The research is based on a single in-depth case that has the scope to be tested in other contexts in future.

Practical implications

This is the first study that demonstrates with real data from an industrial firm the effects of Blockchain on the efficiency gains, reduction on the number of operations and human-processing savings. A detailed description of the Blockchain implementation is provided. Furthermore, this research shows a list of the resources and capabilities needed for building and maintaining a Blockchain in the context of supply chains.

Originality/value

This is the first study that demonstrates with real data from an industrial firm the effects of Blockchain on the efficiency gains, the reduction in the number of operations and human-processing savings. A detailed description of the Blockchain implementation is provided. This paper contributes to the resource-based view of the firm, by demonstrating two new competitive valuable capabilities and a new dynamic capability that organisations develop when implementing and using Blockchain in a supply–demand process. It also contributes to the information processing theory by highlighting the analytics capabilities required to sustain Blockchain-related operations.
Control charts for detection of dead batches during hydrogenation of edible oil
Authors: Chakraborty Soham , Mandal Pathik
Published: October 2019

Purpose

Modeling and inferring about the process using growth models are the problems of enormous practical importance. Growth behavior of melting point (MP) during hydrogenation is found to be nonlinear. The purpose of this paper is to propose a control chart based method for on-line detection of a growth process becoming dead.

Design/methodology/approach

The nonlinear growth kinetics of MP during hydrogenation is modeled as a random walk with drift. In earlier work, the random walk model is developed based on a linear approximation and the control chart is constructed based on this approximate model. Here, an alternative model that does not make use of any such approximation is proposed. The variable drift component of the random walk is estimated following an innovative method of instrumental variable estimation. The model thus obtained is then used to construct a new control chart.

Findings

It is shown that both the control charts are able to detect dead batches satisfactorily, but the new chart is superior to the earlier one.

Originality/value

The authors are not aware of any relevant literature which provides an implementable and practitioner friendly approach to model the usually cumbersome variance function using signal-to-noise ratio and then use the same for estimating the parameters of a nonlinear dynamic growth model.
How does corporate learning orientation enhance industrial brand equity? The roles of firm capabilities and size
Authors: Xie Yi , Zheng Xiaoying
Published: October 2019

Purpose

This paper aims to examine the role of learning orientation in building brand equity for B2B firms. The present research proposes that learning orientation contributes to the development of innovation and marketing capabilities and, in turn, leads to enhanced industrial brand equity. Furthermore, the moderating effect of firm size in these processes is investigated.

Design/methodology/approach

The hypotheses are tested by administering a survey with a set of managers of manufacturing firms in China.

Findings

Innovation capability and marketing capability serve as the mediators between learning orientation and industrial brand equity. The mediating path through innovation capability is stronger for small firms than for large firms.

Research limitations/implications

Learning orientation provides a cultural base for B2B firms to cultivate brand equity. Measurement of industrial brand equity and contingency of its effect requires further investigation.

Practical implications

To transform learning-oriented culture into brand equity, firms need to develop and manage innovation and marketing capabilities. The learning orientation–innovation capability route is more beneficial for small firms.

Originality/value

While a majority of prior literature ignores the impact of organizational culture in driving industrial brand equity, the present research explores learning orientation as a key cultural antecedent of industrial brand equity. A more refined industrial-brand-equity-building mechanism from learning orientation to corporate capabilities and then to brand equity is proposed and tested. The mechanism varies with firm size.
Centrality and community detection: a co-marketing multilayer network
Authors: Fernandes Andreia , Gonçalves Patrícia C.T. , Campos Pedro , Delgado Catarina
Published: October 2019

Purpose

Based on the data obtained from a questionnaire of 595 people, the authors explore the relative importance of consumers, checking whether socioeconomic variables influence their centrality, detecting the communities within the network to which they belong, identifying consumption patterns and checking whether there is any relationship between co-marketing and consumer choices.

Design/methodology/approach

A multilayer network is created from data collected through a consumer survey to identify customers’ choices in seven different markets. The authors focus the analysis on a smaller kinship and cohabitation network and apply the LART network community detection algorithm. To verify the association between consumers’ centrality and variables related to their respective socioeconomic profile, the authors develop an econometric model to measure their impact on consumer’s degree centrality.

Findings

Based on 595 responses analysing individual consumers, the authors find out which consumers invest and which variables influence consumers’ centrality. Using a smaller sample of 70 consumers for whom they know kinship and cohabitation relationships, the authors detect communities with the same consumption patterns and verify that this may be an adequate way to establish co-marketing strategies.

Originality/value

Network analysis has become a widely used technique in the extraction of knowledge on consumers. This paper’s main (and novel) contribution lies in providing a greater understanding on how multilayer networks represent hidden databases with potential knowledge to be considered in business decisions. Centrality and community detection are crucial measures in network science which enable customers with the highest potential value to be identified in a network. Customers are increasingly seen as multidimensional, considering their preferences in various markets.

Authors: Lian Zhiying , Oliver Gillian
Published: October 2019

Purpose

The purpose of this paper is to explore the concept of information culture in Mainland China and apply the information culture framework to an organizational setting.

Design/methodology/approach

The foundation for the research is provided by a review of Chinese and English language literature and a case study of a university library was conducted, involving semi-structured interviews.

Findings

The information culture framework facilitated identification of factors not recognized in previous information culture research, including uniquely Chinese factors of egocentrism, guanxi (relationships), mianzi (face), hexie (harmony) and renqing (mutual benefit). A further finding highlighted the profound differences between archives and library institutions in China.

Originality/value

The paper provides the first step toward further exploring features of Chinese organizational culture which will not only influence information management practices but also highlight the issues relating to collaboration between libraries and archives in China.
Common usage as warrant in bibliographic description
Authors: Dobreski Brian
Published: October 2019

Purpose

Within standards for bibliographic description, common usage has served as a prominent design principle, guiding the choice and form of certain names and titles. In practice, however, the determination of common usage is difficult and lends itself to varying interpretations. The purpose of this paper is to explore the presence and role of common usage in bibliographic description through an examination of previously unexplored connections between common usage and the concept of warrant.

Design/methodology/approach

A brief historical review of the concept of common usage was conducted, followed by a case study of the current bibliographic standard Resource Description and Access (RDA) employing qualitative content analysis to examine the appearances, delineations and functions of common usage. Findings were then compared to the existing literature on warrant in knowledge organization.

Findings

Multiple interpretations of common usage coexist within RDA and its predecessors, and the current prioritization of these interpretations tends to render user perspectives secondary to those of creators, scholars and publishers. These varying common usages and their overall reliance on concrete sources of evidence reveal a mixture of underlying warrants, with literary warrant playing a more prominent role in comparison to the also present scientific/philosophical, use and autonomous warrants.

Originality/value

This paper offers new understanding of the concept of common usage, and adds to the body of work examining warrant in knowledge organization practices beyond classification. It sheds light on the design of the influential standard RDA while revealing the implications of naming and labeling in widely shared bibliographic data.
A drifting phenomenon: organizational change failure in a becoming view
Authors: Bruskin Signe
Published: October 2019

Purpose

The purpose of this paper is to study the phenomenon of organizational change failure through an emic approach. Grounded in empirical examples, the paper unfolds why the phenomenon seems to be missing from the literature of the becoming view (e.g. Tsoukas and Chia, 2002).

Design/methodology/approach

Inspired by the methodological strategy of “studying through,” organizational changes are followed through space and time within the setting of a Nordic bank, from where the empirical data have been collected via longitudinal study. The empirical data are generated through a combination of methods: shadowing, interviews, in situ observations and desk research in order to capture the ever-changing phenomenon of organizational change.

Findings

The paper finds that organizational changes drift away, either by slipping into the everyday practices of the organization, or by drifting away in time when history is reinterpreted. The paper concludes that organizational change failures suffer the same fate as organizational changes more generally and drift away in space and time.

Originality/value

The paper contributes to the becoming view by illustrating how methodologically an ever-changing phenomenon such as organizational change can be studied. Further, it contributes to the field of organizational change failure by unpacking the fate of organizational change failure when change is natural and slippery in nature. The paper includes reflections on what the consequences might be for praxis.
From words to pixels: text and image mining methods for service research
Authors: Villarroel Ordenes Francisco , Zhang Shunyuan
Published: October 2019

Purpose

The purpose of this paper is to describe and position the state-of-the-art of text and image mining methods in business research. By providing a detailed conceptual and technical review of both methods, it aims to increase their utilization in service research.

Design/methodology/approach

On a first stage, the authors review business literature in marketing, operations and management concerning the use of text and image mining methods. On a second stage, the authors identify and analyze empirical papers that used text and image mining methods in services journals and premier business. Finally, avenues for further research in services are provided.

Findings

The manuscript identifies seven text mining methods and describes their approaches, processes, techniques and algorithms, involved in their implementation. Four of these methods are positioned similarly for image mining. There are 39 papers using text mining in service research, with a focus on measuring consumer sentiment, experiences, and service quality. Due to the nonexistent use of image mining service journals, the authors review their application in marketing and management, and suggest ideas for further research in services.

Research limitations/implications

This manuscript focuses on the different methods and their implementation in service research, but it does not offer a complete review of business literature using text and image mining methods.

Practical implications

The results have a number of implications for the discipline that are presented and discussed. The authors provide research directions using text and image mining methods in service priority areas such as artificial intelligence, frontline employees, transformative consumer research and customer experience.

Originality/value

The manuscript provides an introduction to text and image mining methods to service researchers and practitioners interested in the analysis of unstructured data. This paper provides several suggestions concerning the use of new sources of data (e.g. customer reviews, social media images, employee reviews and emails), measurement of new constructs (beyond sentiment and valence) and the use of more recent methods (e.g. deep learning).
The impact of the Emergency Department target upon the discharge decision for people who self-harm
Authors: Haslam Michael Brian , Jones Emma S.
Published: October 2019

Purpose

The purpose of this paper is to consider the influence of the Emergency Department (ED) target wait time upon the discharge decision in ED, specifically for patients who have self-harmed. Pressures to discharge patients to avoid breaching the 4-h target wait time, potentially increase the risk of adverse responses from clinicians. For the patient who has self-harmed, such interactions may be experienced as invalidating and may result in adverse outcomes.

Design/methodology/approach

Secondary data analysis was applied to the retrospective referral data of a Mental Health Liaison Team (MHLT), collected over a period of 11 months from a single hospital in the North of England. In total, 734 episodes of care were referred to the team from ED, where the primary presentation was recorded as self-harm.

Findings

Over half of patients referred to the MHLT from ED having self-harmed were seen after already breaching the target and the potential for a more restrictive outcome reduced. Of those patients seen within 4 h, the potential for a more restrictive treatment option was increased.

Practical implications

Recommendations to improve the patient journey for those who have self-harmed include mental health triage and treatment in clinical areas outside of the target.

Social implications

This study challenges the concept of the target as being realistic and attainable for patients who have self-harmed.

Originality/value

This exploratory study provides a starting point from which to explore the impact of the target time upon discharge decisions and clinical outcomes specifically for those who have self-harmed.
Embracing complex social problems
Authors: Carvalho Hamilton Coimbra , Mazzon Jose Afonso
Published: October 2019

Purpose

This paper aims to expose the inadequacy of social marketing to tackle complex social problems, while proposing an expansion in the discipline’ conceptual repertoire. The goal is to incorporate complexity tools, in particular from the system dynamics field, and the promotion of mindware within a true transdisciplinary paradigm.

Design/methodology/approach

This paper uses literature review to support the proposed theoretical development. It also presents a short case study.

Findings

Most problems that plague our modern societies have a distinctive complex nature that is not amenable to traditional social marketing interventions. Social marketing has simplified the problem of bringing about societal change by thinking that upstream social actors can be influenced in the same way as downstream individuals. This paper shows that this is not the case while proposing a framework to close this gap.

Research limitations/implications

The proposed framework is a theoretical one. It depends on further refinements and actual application to wicked problems.

Practical implications

Complex social problems – or wicked problems – remain widespread in modern societies. Moreover, they are getting worse over time. The paper presents a proposal to redefine the limits of the social marketing discipline so it can be more useful to tackle such problems. Practical approaches such as measuring the success of mindware in the marketplace of ideas are implied in the proposed framework.

Social implications

The increase in complexity of social problems has not been accompanied by an evolution in the discipline of social marketing. The lack of proper conceptual tools has prevented the discipline from contributing to tackling these problems effectively. Some interventions may actually worsen the underlying problems, as illustrated in the paper.

Originality/value

This paper identifies two major gaps associated with the social marketing discipline, in particular the lack of complexity and systems thinking and the forsaking of ideas (mindware) as a legitimate goal of the discipline. This realization corroborates the claim that boundaries among disciplines are often artificial, hindering the proper understanding of complex social problems. In turn, only the use of adequate conceptual lenses makes it possible to devise interventions and programs that tackle actual causes (instead of symptoms) of complex social problems.
The state-of-play in physician health systems leadership research
Authors: Onyura Betty , Crann Sara , Freeman Risa , Whittaker Mary-Kay , Tannenbaum David
Published: October 2019

Purpose

This paper aims to review a decade of evidence on physician participation in health system leadership with the view to better understand the current state of scholarship on physician leadership activity in health systems. This includes examining the available evidence on both physicians’ experiences of health systems leadership (HSL) and the impact of physician leadership on health system reform.

Design/methodology/approach

A state-of-the-art review of studies (between 2007 and 2017); 51 papers were identified, analyzed thematically and synthesized narratively.

Findings

Six main themes were identified in the literature as follows: (De)motivation for leadership, leadership readiness and career development, work demands and rewards, identity matters: acceptance of self (and other) as leader, leadership processes and relationships across health systems and leadership in relation to health system outcomes. There were seemingly contradictory findings across some studies, pointing to the influence of regional and cultural contextual variation on leadership practices as well entrenched paradoxical tensions in health system organizations.

Research limitations/implications

Future research should examine the influence of varying structural and psychological empowerment on physician leadership practices. Empirical attention to paradoxical tensions (e.g. between empowerment and control) in HSL is needed, with specific attention to questions on how such tensions influence leaders’ decision-making about system reform.

Originality/value

This review provides a broad synthesis of diverse papers about physician participation in health system leadership. Thus, it offers a comprehensive empirical synthesis of contemporary concerns and identifies important avenues for future research.
The Internet of Things (IoT): a survey of techniques, operating systems, and trends
Authors: Shammar Elham Ali , Zahary Ammar Thabit
Published: October 2019

Purpose

Internet has changed radically in the way people interact in the virtual world, in their careers or social relationships. IoT technology has added a new vision to this process by enabling connections between smart objects and humans, and also between smart objects themselves, which leads to anything, anytime, anywhere, and any media communications. IoT allows objects to physically see, hear, think, and perform tasks by making them talk to each other, share information and coordinate decisions. To enable the vision of IoT, it utilizes technologies such as ubiquitous computing, context awareness, RFID, WSN, embedded devices, CPS, communication technologies, and internet protocols. IoT is considered to be the future internet, which is significantly different from the Internet we use today. The purpose of this paper is to provide up-to-date literature on trends of IoT research which is driven by the need for convergence of several interdisciplinary technologies and new applications.

Design/methodology/approach

A comprehensive IoT literature review has been performed in this paper as a survey. The survey starts by providing an overview of IoT concepts, visions and evolutions. IoT architectures are also explored. Then, the most important components of IoT are discussed including a thorough discussion of IoT operating systems such as Tiny OS, Contiki OS, FreeRTOS, and RIOT. A review of IoT applications is also presented in this paper and finally, IoT challenges that can be recently encountered by researchers are introduced.

Findings

Studies of IoT literature and projects show the disproportionate importance of technology in IoT projects, which are often driven by technological interventions rather than innovation in the business model. There are a number of serious concerns about the dangers of IoT growth, particularly in the areas of privacy and security; hence, industry and government began addressing these concerns. At the end, what makes IoT exciting is that we do not yet know the exact use cases which would have the ability to significantly influence our lives.

Originality/value

This survey provides a comprehensive literature review on IoT techniques, operating systems and trends.
Intellectual disability and dementia: perspectives on environmental influences
Authors: Sheth Alisa Jordan
Published: October 2019

Purpose

The purpose of this paper is to improve understandings of environmental influences on participation in routine and familiar activities for people with intellectual disabilities and dementia from first-person and caregiver perspectives.

Design/methodology/approach

Four adults with intellectual disabilities and dementia participated in 2 nominal group technique sessions and 12 family and staff caregivers participated in 5 standard focus groups. Transcripts were analyzed utilizing thematic analysis centering the findings from nominal group technique sessions and an ecological systems lens.

Findings

Participants with intellectual disabilities and dementia identified six important themes: activity access, caregiver assistance, social interactions, responsibilities, privacy, and health and wellness. Their perspectives focused primarily at an immediate environment level, while caregiver input added additional understandings from broader ecological systems levels.

Originality/value

This study provides a beginning point to establishing a framework for creating supports and addressing barriers to participation for adults with intellectual disability and dementia based on direct input from potential service consumers and their caregivers. People with intellectual disabilities and dementia provide valuable insights into their experiences through engagement in accessible research.
Shareholder litigation risk and real earnings management: a causal inference
Authors: Liao Qunfeng , Ouyang Bo
Published: October 2019

Purpose

The authors study how shareholder litigation risk impacts a firm’s decision of real earnings management (REM). This paper aims to shed light on how shareholder litigation risk impacts REM. The authors further explore how the intensifying effect varies systematically conditioning on the degree of information asymmetry and the strength of internal corporate governance.

Design/methodology/approach

In this study, the authors use the 1999 Ninth Circuit Court ruling as a quasi-experiment that reduces shareholder litigation risk to address endogeneity and establish a causal inference.

Findings

The difference-in-difference tests suggest lower shareholder litigation risk intensifies REM. In other words, higher litigation risk mitigates REM. Cross-sectional test results suggest the negative effect of decreased shareholder litigation is more pronounced when monitoring difficulty is higher, when information environment is more impoverished and when internal corporate governance is weaker. The negative effect is also stronger in firms with higher sensitivity to legal threats.

Originality/value

Protection of investors’ interest is the focus of corporate governance. Designed as an important corporate governance mechanism, shareholder litigation enables investors to pursue legal actions to recover their losses in the event of corporate misbehaviors. However, whether shareholder litigation is an effective corporate governance tool and beneficial to shareholders and firms is not without controversy. The authors contribute to the debate by providing evidence that supports the argument that shareholder litigation threat significantly disciplines REM, a form of costlier earnings management technique and myopic investment behavior.
