Published: January 2018

ABSTRACTSelective Mutism (SM) is an anxiety disorder often diagnosed in early childhood and characterized by persistent failure to speak in certain social situations but not others. Diagnosing SM and monitoring treatment response can be quite complex, due in part to changing definitions of and scarcity of research about the disorder. Subjective self-reports and parent/teacher interviews can complicate SM diagnosis and therapy, given that similar speech problems of etiologically heterogeneous origin can be attributed to SM. The present perspective discusses the potential for passive audio capture to help overcome psychiatry’s current lack of objective and quantifiable assessments in the context of SM. We present evidence from two pilot studies indicating the feasibility of using a digital wearable device to quantify child vocalization features affected by SM. We also highlight limitations in the design and implementation of this preliminary work that can help guide future efforts.
Solitary wave collisions by double-dam-broken simulations with the MPS method
Authors: Sanchez-Mondragon Joel , Vazquez-Hernandez Alberto Omar 
Published: January 2018

PurposeThe paper aims to apply a modified version of the MPS method to a double-dam-breaking test in which high dispersion zones and high natural clusterization zones are present, such as when the water column collapses into two sides and the two solitary waves collide, respectively.Design/methodology/approachThe work takes advantage of the mixed source term from the cheaper computational version of the moving particle semi-implicit (MPS) method to reduce one step from the MPS classical algorithm. The proposed test can be successfully simulated by applying modifications to the variance parameter in the Laplacian operator and gradient model.FindingsThe results show stable behavior in dispersion and clusterization zones. Also, the collision and merging produced by solitary waves was successfully simulated.Research limitations/implicationsThe main limitation in this work was the development of a comparison between the obtained results and the simulations with the original cheaper computational version of the MPS, this limitation is due to the overestimation of inter particle repulsive forces from its gradient model.Practical implicationsThe application of solitary waves is of paramount importance in a number of applications, and this stems from the fact that the interaction of solitary waves with ships and other floating structures could generate highly deformed and complex free surface flows.Social implicationsFor future work, the modified version of the MPS method can be applied in flow over sill base simulations, in close and open channels, and in simulating breaking waves to determine impact pressures by using solitary wave propagation.Originality/valueThe simulation of interaction of large groups of particles as in the case when two solitary waves collide could cause severe instability problems in pressure, causing the computer analysis to stop. MPS classical algorithm takes into account an explicit step that, in this case, may provoke the problem. For this reason, the cheaper version of MPS method is used to correctly simulate solitary wave interactions.
Numerical investigation of flow features in the vaneless region of a centrifugal pump by large eddy simulation
Authors: Huang Xianbei , Li Yaojun , Liu Zhuqing , Yang Wei 
Published: January 2018

Purpose
The purpose of this paper is to obtain a better understanding of the rotor–stator interaction in the vaneless region of a centrifugal pump.

Design/methodology/approach
A third-order sub-grid scale (SGS) model containing the rotation rate tensor named the dynamic cubic non-linear model (DCNM) is used for simulating the flow field in a centrifugal pump with a vaned diffuser. The pressure coefficient and velocity distributions are compared with the experimental data. Focusing on the vaneless region, the pressure pulsation, Reynolds stress pulsation and Reynolds stress transport equation are analyzed.

Findings
The comparison of the calculation results with the experimental data indicates that the DCNM can accurately capture the distributions of pressure and velocity in the vaneless region. Based on the instantaneous pressure signals, the pressure pulsation is analyzed to show that in the vaneless region, the dominant frequency near the impeller is twice the blade passing frequency, whereas it is equal to the blade passing frequency near the diffuser. Further exploration of the Reynolds stress pulsation shows the correlation between the two variables. Additionally, the extreme low frequency of Reynolds stress near the diffuser is found to be related to the rotation instability. To explore the turbulence characteristics in the vaneless region, the Reynolds stress transportation equation is studied. In the vaneless region, the rotation term of the Reynolds stress transport equation is negligible compared to the production term, although the rotation instability is obvious near the diffuser. The production of the Reynolds stress plays the role of redistributing the energy from the uu component to the vv component, except for the region near the impeller outlet.

Originality/value
The third-order SGS model DCNM has proved to be promising in simulating the rotor–stator interaction. The analysis of the rotation instability and the Reynolds stress transport equation shed light on the further understanding of the rotor–stator interaction.
Factors and maturity level of entrepreneurial universities in Spain

Published: January 2018

PurposeThe entrepreneurial university is being widely studied, given its importance as an agent in economic and social development. This paper presents the findings of a study that had a twofold objective. First, it sought to establish a model of maturity for the measurement of the level of academic entrepreneurship in universities. Second, it aimed to apply this maturity model to a sufficiently wide and varied sample of faculties to discover their current level of academic entrepreneurship, as well as their differences by area of knowledge, type of university and autonomous region in Spain.Design/methodology/approachA questionnaire was designed with items grouped into 14 blocks that defined the entrepreneurial university according to the model previously developed. The questionnaire was answered by 84 deans/directors belonging to different faculties/universities from six Spanish regions.FindingsThe findings showed that the Spanish universities stand out in four areas: internationalisation, use of active methodologies, mission and strategy and management team support. However, the legal and administrative context, the funds for entrepreneurship and the training of staff in entrepreneurship are not sufficiently developed. Significant differences were observed between regions but not by type of university or area of knowledge.Originality/valueThe results provide an innovative model that explains the factors that define the entrepreneurial university, as well as guidelines for universities to move forward in developing stages.
From bricks-and-mortar to bricks-and-clicks
Authors: Wollenburg Johannes , Hübner Alexander , Kuhn Heinrich , Trautrims Alexander 
Published: January 2018

PurposeThe advent of grocery sales through online channels necessitates that bricks-and-mortar retailers redefine their logistics networks if they want to compete online. Because the general understanding of such bricks-and-clicks logistics systems for grocery is still limited, the purpose of this paper is to analyze the internal logistics networks used to serve customers across channels by means of an exploratory study with retailers from different contexts.Design/methodology/approachA total of 12 case companies from six European countries participated in this exploratory study. Face-to-face interviews with managers were the primary source for data collection. The heterogeneity of the sample enabled the authors to build a typology of logistics networks in grocery retailing on multiple channels and to understand the advantages of different warehousing, picking, internal transportation and last-mile delivery systems.FindingsBricks-and-mortar grocery retailers are leveraging their existing logistics structures to fulfill online orders. Logistics networks are mostly determined by the question of where to split case packs into customer units. In non-food logistics, channel integration is mostly seen as beneficial, but in grocery retailing, this depends heavily on product, market and retailer specifics. The data from the heterogeneous sample reveal six distinct types for cross-channel order fulfillment.Practical implicationsThe qualitative analysis of different design options can serve as a decision support for retailers developing logistics networks to serve customers across channels.Originality/valueThe paper shows the internal and external factors that drive the decision-making for omni-channel (OC) logistics networks for previously store-based grocery retailers. Thereby, it makes a step toward building a contingency and configuration theory of retail networks design. It discusses in particular the differences between grocery and non-food OC retailing, last-mile delivery systems and market characteristics in the decision-making of retail networks design.
Motives of mergers and acquisitions by state-owned enterprises
Authors: Florio Massimo , Ferraris Matteo , Vandone Daniela 
Published: January 2018

Purpose
This paper looks at state-owned enterprises (SOEs) from the angle of the market for corporate control and analyzes in detail the reported rationales of a sample of 355 mergers and acquisition (M&A) deals performed by SOEs as acquirers over the period 2002-2012. The purpose of this paper, after having created a taxonomy of deal motivations, is to empirically test two alternative hypotheses: deviation vs convergence of M&A deal rationales between state-owned and private enterprises.

Design/methodology/approach
The data set is obtained by combining firm-level information from two sources, Zephyr and Orbis (Bureau Van Dijk). A recursive algorithm is developed to infer the ownership nature of the enterprises at the time the deal took place and then the authors double-checked the identity of the global ultimate owner by visual inspection of all the available information. Motivations are analyzed through a case-by-case analysis and classified into several categories, thereby providing a taxonomy of rationales behind SOE M&As and discussing their differences and similarities relative to private firms.

Findings
More than 60 percent of the deals performed by SOEs as acquirers are driven by “shareholder value maximization” motives, similarly to private enterprise acquirers. The other 40 percent of deals are almost equally spread among three rationales that specifically relate to the role of modern state capitalism in the economy. “Financial distress” motivation, which is the only one clearly deviating from the objectives of profit maximization typical of private ownership, is far less important than the others.

Research limitations/implications
The paper does not analyze the case studies in detail. Neither does it correlate the evidence with the quality of corporate governance or the quality of institutions in the country. This would be interesting in order to discover whether the alignment of objectives between public and private enterprises is enhanced by certain features of public sector management, as suggested by the OECD (2015) Guidelines.

Practical implications
The paper suggests some policy implications in terms of reforms of the corporate governance of the SOEs and accountability of their management against clearly stated public missions. It also calls for the need for citizens to be informed in a transparent way about the rationales of major M&A deals when a SOE is on the acquirer side, and the consistency of such rationales with the mission assigned by governments to the enterprises they own. Finally, it underlines that regulatory concerns raised in many countries by the rise of cross-border SOE M&As are in most of the cases unfounded.

Originality/value
Existing literature has mainly focused on private corporate M&A deals or has just disregarded the ownership status of the acquiring firm. This paper focuses on the motivations for SOE deals in order to elaborate a taxonomy of SOE deal rationales and to identify the differences and similarities between private corporate firms.
Challenging popular representations of child trafficking in football
Authors: Esson James , Drywood Eleanor 
Published: January 2018

Purpose
Reports of human trafficking within the football industry have become a topic of academic, political and media concern. The movement of and trade in aspirant young (male) footballers from West Africa to Europe, and more recently to Asia, dominates these accounts. The paper aims to discuss these issues.

Design/methodology/approach
This paper provides an overview of scholarship on this topic, with a specific focus on exploring how this form of human trafficking intersects with the broader debates over children’s rights in the context of exploitation tied to the irregular forms of migration.

Findings
The paper illustrates how popular narratives associated with the trafficking of young West African footballers mimic stereotypical portrayals of child trafficking, which have implications for the solutions put forward. It is argued that popular representations of football-related child trafficking are problematic for several reasons, but two are emphasised here. First, they perpetuate a perception that the mobility of young African footballers entails a deviant form of agency in need of fixing, while simultaneously disassociating the desire to migrate from the broader social structures that need to be addressed. Second, and relatedly, they result in regulations and policy solutions that are inadvertently reductive and often at odds with the best interests of the children they seek to protect.

Originality/value
This an original study of the narratives associated with the trafficking of young West African footballers and those of child trafficking.
Prediction model of business success or failure for Palestinian small enterprises in the West Bank
Authors: Baidoun Samir D. , Lussier Robert N. , Burbar Maisa , Awashra Sawsan 
Published: January 2018

Purpose
The aim of this study is to examine the factors that lead to success or failure of a small business in the West Bank of Palestine.

Design/methodology/approach
This study methodology is a survey research, testing the Lussier model of business success and failure with a sample of 246 small businesses (90 failed and 156 successful) to better understand the reasons of their success or failure using logistic regression statistical analysis.

Findings
The model is significant (p = 0.000); it will predict a group of businesses as successful or failed more accurately than random guessing 99 per cent of the time. The model will also predict a specific small firm as successful or failed 94 per cent of the time vs. 50 per cent for random guessing. The r-square is very high (r = 0.70), indicating that the model variables are, in fact, significant predictors of success or failure. Results indicate that having adequate capital, keeping good records with financial controls, making plans and getting professional advice on how to manage the firm are the most important factors for the viability and success of small businesses.

Practical implications
With the high rate of small business failure globally, results of this study provide a list of variables that contribute to the success of small firms. Firms that focus on these important factors will increase their odds of success. Thus, avoiding failure, firms better utilize resources that contribute to economic growth.

Originality/value
This is the first study that looks at success and failure of small businesses in Palestine. There is no one single accepted theory that may be applied to small businesses. This paper aims to further contribute to the global validity of Lussier success and failure model moving toward a theory to better understand why some businesses succeed and others fail.
How community event narratives contribute to place branding
Authors: Walters Trudie , Insch Andrea 
Published: January 2018

Purpose
To date, the importance of smaller, local community events in the place branding process has been overlooked in the place branding and event studies literature – yet they are recognised as a means of increasing the attractiveness of a place for residents, through building a sense of community and contributing to quality of life. The purpose of this paper is to make clear the contribution of community event narratives to place branding.

Design/methodology/approach
A qualitative approach was adopted. The public narratives of a portfolio of 14 community events (from event websites, press releases and media discourse, local government strategic policy documents) were examined. An inductive thematic analysis was conducted, and a visual framework for analysing and discussing the findings was created.

Findings
Community event narratives provide a useful resource that could be drawn upon by place branding practitioners to reach potential new residents who share similar ideals as local residents. The findings from this study demonstrate that local community event narratives do indeed tell “stories about who we are”.

Practical implications
This paper has implications for place branding initiatives seeking to attract new residents, particularly where there is a sense of fear and resistance from residents about “outsiders” moving in.

Originality/value
This paper presents an alternative model to the traditional city branding campaigns that seek to attract new residents, in the form of a values-based event-led branding strategy that may be more appropriate and compatible with local stakeholder goals.
Corporate social responsibility influences employee engagement
Authors: Tsourvakas Georgios , Yfantidou Ioanna 
Published: January 2018

PurposeThe purpose of this study is to explore the influence of corporate social responsibility (CSR) on employee engagement, motivation and job satisfaction on the staff members of two multinational companies in Greece (Procter & Gamble [P&G] and Unilever).Design/methodology/approachA quantitative methodology in the form of statistical analysis of the results was derived from the responses on an employee engagement questionnaire.FindingsFindings show that employees are proud to identify themselves with companies that have a caring image. CSR is also positively linked to employee engagement for both companies.Research limitations/implicationsThe small size of the sample is a limitation because it leaves no room for generalising the findings. Secondly, although some of the hypotheses were backed by the data, he findings are not strong enough, as the reported correlations are too small.Practical implicationsPractitioners and marketing professionals can benefit from this research by absorbing the fact that employees feel engaged, satisfied and motivated when they play a positive role in the society through their work. As a result, it would be constructive for professionals to plan CSR strategies and involve employees both in planning and execution of those strategies.Originality/valueUnlike other studies, the authors tried to examine the link between CSR and employee behaviour amid Greece’s financial difficulties.
Corporate social reporting and legitimacy in banking: a longitudinal study in the developing country
Authors: Islam Mohammad Tazul , Kokubu Katsuhiko 
Published: January 2018

PurposeThe purpose of this paper is to examine the development of corporate social (CS) reporting in the developing country’s banking industry from the legitimacy theory perspective – Bangladesh as a case.Design/methodology/approachThis study uses the longitudinal aspects and analyzes the content of annual reports using the ISO26000 standard with some country- and industry-specific adjustments as the method of data coding. All Dhaka Stock Exchange-listed banks (30 of 47, 2013) and 282 annual reports with 46 reporting items have been used for data analysis during a 10-year period (2004-2013). A CS reporting index has been constructed for this purpose of analysis.FindingsThe key findings are that the main impetus driving the development of CS reporting was the stakeholder initiatives; the CS reporting index was less than 20 in 2004, and it increased linearly and reached around 60 in 2013 because of the legitimization of the new banking process through social perceptions. This study explains that the contemplation of the legitimacy theory argument can similarly be applied to the developing countries as well as to the banking industry’s context.Research limitations/implicationsThe main implication of this study is the extension of the broader thrust of the legitimacy theory argument in the developing country’s banking industry, such as that of Bangladesh.Originality/valueThis study contributes to the documentation of the CS reporting practices of the developing country’s banking industry where there is a lack of published longitudinal studies from the legitimacy theory perspective.
Hyperuricemia in Asian psoriatic arthritis patients
Authors: Lai Tin Lok , Yim Cheuk Wan , Wong Pui Yan , Leung Man Chi , Ng Woon Leung 
Published: January 2018

AbstractAimIt is generally accepted that hyperuricemia is commonly associated with psoriatic arthritis (PsA). However, variations in ethnicity, diet and habitat may contribute to differences in prevalence and risk factors for hyperuricemia in PsA patients. Moreover, Asian specific data is deficient. The primary objective of the present study was to determine the prevalence of hyperuricemia among PsA patients. The secondary objective was to explore its associated risk factors.MethodsThis was a multi‐center, cross‐sectional observational study of 160 PsA patients from local Rheumatology clinics. Serum uric acid (SUA) level and other clinical parameters were measured and hyperuricemia was defined as SUA level greater or equal to 360 umol/L in females and 420 umol/L in males.ResultsForty‐nine of 160 patients (30.6%) had hyperuricemia, of which 32 were men, 17 were women. Among those with hyperuricemia, mean SUA level was 500.7 ± 95.9 umol/L and 427.8 ± 83.1 umol/L in males and females, respectively. Univariate analysis found: (i) overweight status; (ii) obesity; (iii) Psoriasis Area and Severity Index; (iv) body surface area; (v) severe skin involvement, as being potentially associated with hyperuricemia. Regression model identified overweight status increased the likelihood of hyperuricemia in PsA, with an odds ratio of 4.4 (95% CI: 2.0–9.5). Furthermore, there was moderately positive correlation (r = 0.37) between body mass index (BMI) and SUA level. No associations were found between arthritis conditions and duration, lipid profile, creatinine clearance; and hyperuricemia.ConclusionA significant proportion of PsA patients had asymptomatic hyperuricemia. It was closely related with BMI, which represented metabolic dysregulation; but not with severity of skin disease, joint involvement or renal function.
