The competition effect of new entry on mutual fund incumbents in China
Authors: Feng Xunan , Xu Jin , Wang Ying , Tang Chunyan 
Published: February 2017

Purpose
Using the sample between 2005 and 2011, the purpose of this paper is to investigate the effect of a new fund entry on incumbents using the overlap measure in portfolio holdings.

Design/methodology/approach
Empirical methodology is used in this study.

Findings
The authors find that incumbents that have a higher overlap with the entrants underperform subsequently. Based on the characteristic-based approach of Daniel et al. (1997), the authors find that the characteristic selectivity component is negatively correlated with the overlap measure, and thereby the decline in performance is driven by the stock-picking ability. The authors also discuss the unobserved actions of incumbents using the approach proposed by Kacperczyk et al. (2008) and find that incumbent unobserved actions do not benefit mutual fund investors in China. Finally the authors find that investors respond to the supply-side competition between entrants and incumbents quickly. These findings help us understand the mutual fund completion in China.

Originality/value
The findings in this study can help scholars, industry experts and regulatory authorities to understand the effect of competition in Chinese mutual fund industry.
Analyst’s ability, media selection and investor interests: evidence from China
Authors: Yin Yugang , Tan Bin 
Published: February 2017

Purpose
The purpose of this paper is to find out whether the election of star analysts leads to the conflict of interests between analysts\institutional investors and individual investors. And then, further investigate how the election results to influence the individual investors’ decision making.

Design/methodology/approach
Given the fact that earnings forecasts and stock ratings are the most important foundations for the investor’s investment decision, the authors investigate the relationship among the earnings forecasts, abnormal returns and the election of star analyst. This paper further analyzes the impact factors on investors’ decision. The data used in this paper for star analysts’ information, analysts’ forecast and recommendations, as well as stock performances-related data are from 2005 to 2012.

Findings
This paper finds that mass media cannot select analysts with high forecast accuracy, and then misleads investors. It demonstrates that the analysts with poorer forecast ability and more optimistic stock recommendations are more prone to be entitled as star analysts by mass media, and these titled star analysts tend to show a poorer performance. Therefore, the star analyst worsens investors’ cognition on analysts forecast ability and then misleads investors’ decision making.

Social implications
Media plays a critical role in corporate governance, information collection and diffusion and reducing the information asymmetry, however, it is good to know the role of media in financial markets from a broader perspective. Because media may also bring negative factors to the financial markets such as misguiding the investors and intensify the conflict of interests between analyst and individual investors.

Originality/value
This paper supports a new perspective of the role of mass media in financial market, which is different from existing studies.
Combinations of eigenspace and GMM with Kinect sensor-extracted action gesture features for person identity recognition
Authors: Ding Ing-Jr , Wu Zong-Gui 
Published: February 2017

PurposeThe Kinect sensor released by Microsoft is well-known for its effectiveness on human gesture recognition. Gesture recognition by Kinect has been proved to be an efficient command operation and provides an additional human-computer interface in addition to the traditional speech recognition. For Kinect gesture recognition in the application of gesture command operations, recognition of the active user making the gesture command to Kinect will be an extremely crucial problem. The purpose of this paper is to propose a recognition method for recognizing the person identity of an active user using combined eigenspace and Gaussian mixture model (GMM) with Kinect-extracted action gesture features.Design/methodology/approachSeveral Kinect-derived gesture features will be explored for determining the effective pattern features in the active user recognition task. In this work, a separate Kinect-derived feature design for eigenspace recognition and GMM classification is presented for achieving the optimal performance of each individual classifier. In addition to Kinect-extracted feature designs for active user recognition, this study will further develop a combined recognition method, called combined eigenspace-GMM, which properly hybridizes the decision information of both the eigenspace and the GMM for making a more reliable user recognition result.FindingsActive user recognition using an effective combination of eigenspace and GMM with well-developed active gesture features in Kinect-based active user recognition will have an outstanding performance on the recognition accuracy. The presented Kinect-based user recognition system using the presented approach will further have the competitive benefits of recognition on both gesture commands and providing users of gesture commands.Originality/valueA hybridized scheme of eigenspace and GMM performs better than eigenspace-alone or GMM-alone on recognition accuracy of active user recognition; a separate Kinect-derived feature design for eigenspace recognition and GMM classification is presented for achieving the optimal performance of the individual classifier; combined eigenspace-GMM active user recognition belonging to model-based active user recognition design has a fine extension on increasing the recognition rate by adjusting recognition models.
An approach for the numerical prediction of the compressible supercavitating flows over ultrahigh-speed underwater object
Authors: Chen Ying , Lu Chuanjing , Chen Xin , Li Jie , Gong Zhaoxin 
Published: February 2017

Purpose
Ultrahigh-speed projectile running in water with the velocity close to the speed of sound usually causes large supercavity. The computation of such transonic cavitating flows is usually difficult, thus high-speed model reflecting the compressibility of both the liquid and the vapor phases should be introduced to model such flow. The purpose of this paper is to achieve a model within an in-house developed solver to simulate the ultrahigh-speed subsonic supercavitating flows.

Design/methodology/approach
An improved TAIT equation adjusted by local temperature is adopted as the equation of state (EOS) for the liquid phase, and the Peng-Robinson EOS is used for the vapor phase. An all-speed variable coupling algorithm is used to unify the computations and regulate the convergence at arbitrary Mach number. The ultrahigh-speed (Ma=0.7) supercavitating flows around circular disk are investigated in contrast with the case of low subsonic (Ma=0.007) flow.

Findings
The characteristic physical variables are reasonably predicted, and the cavity profiles are compared to be close to the experimental empirical formula. An important conclusion in the compressible cavitating flow theory is verified by the numerical result that, at any specific cavitation number the cavity’s size and the drag coefficient both increase along with the rise of Mach number. On the contrary, it is found as well that the cavity’s slenderness ratio decreases when Mach number goes up. It indicates that the compressibility has different influences on the length and the radius of the supercavity.

Originality/value
A high-speed model reflecting the compressibility of both the liquid and the vapor phases was suggested to model the ultrahigh-speed supercavitating flows around underwater projectiles.
Initiatives that diminish the biases of recruiters against people who disclose or demonstrate a diagnosed mental disorder
Authors: Moss Simon , Vemuri S. Ram , Hedley Darren , Uljarevic Mirko 
Published: February 2017

PurposeThe purpose of this paper is to explore the possibility that several workplace initiatives could stem the biases of recruiters against people who disclose or demonstrate diagnosed mental disorders. Specifically, in many nations, the level of unemployment in people who experience mental disorders is rife. Arguably, employers exhibit various biases that disadvantage people who disclose or demonstrate mental disorders; for example, recruiters tend to orient attention to the limitations, instead of the strengths, of job candidates. Because of these various biases, employers may reject applicants who acknowledge or manifest a mental disorder, even if these candidates would have been suitable.Design/methodology/approachTo substantiate these premises, the authors analyzed established taxonomies of cognitive biases to identify which of these biases are likely to deter the employment of people with mental disorders. In addition, the authors applied several theories, such as the future self-continuity hypothesis, to uncover a variety of initiatives that could redress these biases in the future.FindingsThe authors uncovered five constellations of biases in recruiters that could disadvantage individuals who disclose or demonstrate mental disorders. Fortunately, consistent with the meaning maintenance model and cognate theories, when the vision and strategy of organizations is stable and enduring, these biases diminish, and people who report mental disorders are more likely to be employed.Originality/valueThis paper shows that initiatives that promote equality and stability in organizations could diminish stigma against individuals who experience mental disorders.
Engaging diversity in academia: manifold voices of faculty
Authors: Desivilya Helena , Borochowitz Dalit Yassour , Bouknik Shalom , Kalovski Geke , Lavy Ilana , Ore Liora 
Published: February 2017

Purpose
The purpose of this paper is to examine the perspectives of academic staff on issues of diversity and social schisms: capturing their perceptions of the complex relations at an academic campus positioned in an intricate sociopolitical context. It also explored how the faculty’s construal of diversity and social divisions inform their educational practices.

Design/methodology/approach
The study employed a qualitative approach using grounded theory methodology. Data collection was based on semi-structured in-depth interviews with 20 diverse faculty members from different departments in a Northern Israeli college. The interviews were transcribed and processed into main themes and categories.

Findings
The findings revealed two main themes: “Diversity awareness” depicting recognition and sensitivity to the complex social context in the college, strategies of directly engaging with it, downplaying or overlooking the intricacies, and “Practices” describing the practical translations of the educational credos into teaching practice. Both themes reflected a myriad of faculty voices.

Social implications
The study illuminated the challenges posed by social schisms, inequalities, and diversity for the faculty who need to grapple with the intricacies on a daily basis. More open dialogue and debates by the protagonists are needed to increase awareness of diversity and experimenting with different ways of addressing the intricacies.

Originality/value
Empirical evidence of the organizational actors’ predicaments, their diverse patterns of coping with intricacies, and the factors underlying their choices contribute to the body of knowledge on managing diversity in vivo by real women and men with different backgrounds and experiences.
Emergency care usage and longevity have opposite effects on health insurance rates
Authors: Piulachs Xavier , Alemany Ramon , Guillen Montserrat 
Published: February 2017

PurposeThis paper aimed to study the price of health insurance for individuals aged 65 years and over.Design/methodology/approachA sample of private health policyholders in Spain is analysed. Joint models are estimated for men and women, separately. A log-linear model of the transformed cumulated number of claims associated with emergency room occupation, ambulance use and hospitalization is estimated, together with a proportional hazard survival model.FindingsThe association between the longitudinal process of severe medical care and the survival time process is positive and highly significant for both men and women. An increase in the price of health insurance because of the effect of a larger number of emergency care demand events is slightly offset by the decrease in expected longevity.Research limitations/implicationsThe effect of an increase in the number of claims is small compared to the reduction in survival, so age still plays a central role in ratemaking.Practical implicationsHigh rates of health insurance for elderly insureds should be compensated with younger insureds in the portfolio.Social implicationsAffordable health insurance premiums for elderly people are difficult to obtain only with strict actuarial principles.Originality/valueThe proposed methodology allows dynamic rates to be designed, so that the price of health insurance can change as new usage information becomes available.

Servant leadership and positive organizational behaviour: the road ahead to reduce employees’ turnover intentions
Authors: Dutta Sumedha , Khatri Puja 
Published: February 2017

PurposeOver time, interest in servant leadership has increased manifold both in academic research and the popular press. These rampant developments have set the stage for addressing the worthiness of servant leadership’s theory. Empirical studies undertaken by numerous scholars (Farlinget al., 1999; Bass, 2000; Page and Wong, 2000; Russell and Stone, 2002; Sendjaya and Serros, 2002; Dennis and Winston, 2003; Smithet al., 2004; Stoneet al., 2004; Dennis and Bocarnea, 2005; Humphreys, 2005) have surfaced significant findings supporting relevance of servant leadership in organizational context; however, an absence of universal definition and its measures impinges on this concept. Noticeably missing from research attention has been the effect of servant leadership in promoting positive organizational behaviour among organizational employees. Thus, this paper aims to explore the available literature on servant leadership with a view to establish a servant leader’s role in instilling and facilitating positive organizational behaviour in the workplace. Moreover, the purpose is also to determine whether the positive organizational behaviour inculcated among the employees through a servant leader helps in reducing their turnover intentions.Design/methodology/approachUsing different keywords, relevant research papers on Google Scholar were selected. Also, several online databases like Emerald Management, Elseiver, EBSCO Host, etc., were accessed for conducting this exploratory study.FindingsTo examine the various convergent and divergent dimensions of the major constructs, numerous definitions and scholarly work of renowned practitioners have been collated through an extensive literature review. To put forth a comprehensive picture encompassing the noteworthy findings of the studies pertaining to the major construct, a tabular representation has been made.Originality/valueThis is the first study wherein the linkage about servant leadership and positive organizational behaviour in organizational context has been talked about. The paper carries value as the literature pertaining to servant leadership in published domain is still in its nascent stage. The repertoire of literature, presented here, will provide a clear direction to the future researchers who wish to pursue their study in this area.
Capital or people – what is the true purpose of education?
Authors: Ali Tanweer 
Published: February 2017

Purpose
The purpose of this study is to present the book Education, Economy and Society, edited by Salim Vally and Enver Motala (UNISA Press, Pretoria, 2014), which highlights the main concepts introduced and discussed.

Design/methodology/approach
The study primarily summarizes the critique of human capital theory (HCT) which is developed in the book. This is done using different approaches and is comprehensive in scope. The study also introduces some of the alternative visions of education as presented by the contributing authors. The author of the review also draws on other literature which addresses the same fields.

Findings
HCT dominates the discourse on the role of education in society, but the concept is hard to measure and evidence of its importance is scant. Despite the criticism of this theory, it continues to dominate the mainstream economic theory.

Research limitations/implications
The main premise merits more systematic study, ideally drawing on more extensive literature, and extending beyond the confines of any one country. As a review, this study aimed to maintain a focus on this one important collection.

Social implications
HCT tends to promote a view of education as a tool of material economic progress. This excludes a discussion of social justice and de-emphasizes the role of education in advancing individual fulfilment and in strengthening democratic values. A view of useful human activity outside of production within a corporate environment is also ignored. This book covers all of these ideas.

Originality/value
This study draws attention to an important book which discusses the proper role of education in economic development and critiques policy making in South Africa. The book is broad enough in scope to be of relevance to educators, academics and policy makers in the developing and developed worlds.

SummaryBacteria of the genus Thiomonas are found ubiquitously in arsenic contaminated waters such as acid mine drainage (AMD), where they contribute to the precipitation and the natural bioremediation of arsenic. In these environments, these bacteria have developed a large range of resistance strategies among which the capacity to form particular biofilm structures. The biofilm formation is one of the most ubiquitous adaptive response observed in prokaryotes to various stresses, such as those induced in the presence of toxic compounds. This study focused on the process of biofilm formation in three Thiomonas strains (CB1, CB2 and CB3) isolated from the same AMD. The results obtained here show that these bacteria are all capable of forming biofilms, but the architecture and the kinetics of formation of these biofilms differ depending on whether arsenite is present in the environment and from one strain to another. Indeed, two strains favoured biofilm formation, whereas one favoured motility in the presence of arsenite. To identify the underlying mechanisms, the patterns of expression of some genes possibly involved in the process of biofilm formation were investigated in Thiomonas sp. CB2 in the presence and absence of arsenite, using a transcriptomic approach (RNA‐seq). The findings obtained here shed interesting light on how the formation of biofilms, and the motility processes contribute to the adaptation of Thiomonas strains to extreme environments.
Differences in internalization and growth of Escherichia coli O157:H7 within the apoplast of edible plants, spinach and lettuce, compared with the model species Nicotiana benthamiana
Authors: Wright Kathryn M. , Crozier Louise , Marshall Jacqueline , Merget Bernhard , Holmes Ashleigh , Holden Nicola J. 
Published: February 2017

SummaryInternalization of food‐borne bacteria into edible parts of fresh produce plants represents a serious health risk. Therefore, internalization of verocytotoxigenic E. coli O157:H7 isolate Sakai was assessed in two species associated with outbreaks, spinach (Spinacia oleracea) and lettuce (Lactuca sativa) and compared to the model species Nicotiana benthamiana. Internalization occurred in the leaves and roots of spinach and lettuce throughout a 10 day time‐course. The plant species, tissue type and inoculum dose all impacted the outcome. A combination of low inoculum dose (~102 CFU) together with light microscopy imaging highlighted marked differences in the fate of endophytic E. coli O157:H7 Sakai. In the fresh produce species, bacterial growth was restricted but viable cells persisted over 20 days, whereas there was > 400‐fold (~2.5 Log10) increase in growth in N. benthamiana. Colony formation occurred adjacent to epidermal cells and mesophyll cells or close to vascular bundles of N. benthamiana and contained components of a biofilm matrix, including curli expression and elicitation, extracellular DNA and a limited presence of cellulose. Together the data show that internalization is a relevant issue in crop production and that crop species and tissue need to be considered as food safety risk parameters.
