The effect of leadership style on talent retention during Merger and Acquisition integration: evidence from China

Abstract: Leadership and talent retention are critical HR-related components in post-merger and acquisition (M&A) integration, but the extent to which these factors interact with each other and eventually contribute to the success of post-M&A integration is under-explored. The present study investigates the effect of leadership styles on talent retention strategies and on the effectiveness of post-M&A integration in a Chinese context. Based on in-depth examination of an M&A case study, we propose that an authoritative, coaching, task-focused and relationship-focused approach has a positive influence on talent retention and effective post-M&A integration in a Chinese context. As far as talent retention strategies are concerned, authoritative leaders use communication, whereas leaders adopting a coaching style use an incentive structure to positively influence talent retention. Furthermore, task-focused leaders use position and performance in order to identify and retain talented employees. By contrast, relationship-focused leaders emphasize the guanxi network, communication and an incentive structure in their strategies of talent retention.

The Turbine Performance of Centrifugal Pumps: A Comparison of Prediction Methods

Abstract: Standard centrifugal Dumps may be operated in reverse as water turbines, and for hydroelectric plums of less than 100 kW (micro- hydro) they are often cheaper than specifically designed turbines. However, in order to use a pump in a micro-hydro scheme, the turbine performance-must be found either by testing or by calculation. Several methods have been suggested for predicting the turbine performance based on the data for pump performance at best efficiency, but they produce a wide range of results.In this paper, eight such methods are compared using an analysis of the effects of poor turbine prediction on the operation of a pump as turbine at a typical micro hydro site. The comparison uses the results of turbine tests on 35 pumps of various types and sizes, some of which have come from the author's own tests. None of the eight methods gives an accurate prediction for all of the pumps but one of the methods can be recommended as a first estimate of the turbine performance.

Clinical Interventions for Technology-Based Problems: Excessive Internet and Video Game Use

Abstract: Psychological problems arising from excessive use of digital technologies, particularly in relation to the Internet and video games, are of growing clinical concern. Although there is no consensus whether technology-based problems constitute primary psychopathologies that should be recognized as clinical disorders, a significant number of problem users have used clinical treatment services. There is therefore a growing need for the mental health community to be aware of available clinical treatments for technology-based problem behaviors and the efficacy of these treatments. This article presents an overview of the prevalence of technology-based problems in Eastern and Western countries and the known cognitive-behavioral dimensions of problematic technology use. We also consider issues related to the assessment of technologybased problems, and critically review clinical treatments for technology-based problems. Keywords: video game; Internet; technology; addiction There is growing academic interest in psychological problems arising from excessive use of digital technologies, particularly in relation to the Internet and video games. Some researchers have proposed that, in some severe cases, technology-based problematic behaviors may be conceptualized as a form of addiction, or as similar in its clinical presentation to Diagnostic and Statistical Manual of Mental Disorders, Text Revision (DSM-IV-TR) listed disorders including impulse control disorders such as pathological gambling (Gentile, 2009; Griffiths, 1995), and substance-related disorders (Rehbein, Kleimann, & Mossle, 2010). However, to date, the proposed disorders of "Internet addiction" (Shapira et al., 2003) and "video game addiction" (Ko, Yen, Chen, Chen, & Yen, 2005) have not been formally recognized as valid psychiatric disorders within clinical nomenclature (Blaszczynski, 2006). Critics of these proposed disorders argue that available research evidence is currently inadequate to determine whether technology-related problems in fact constitute "primary" psychopathologies (Shaffer, Hall, & Vander Bilt, 2000), or simply represent new manifestations of symptoms or dimensions of other known disorders such as depression, anxiety, or obsessive-compulsive disorder (Wood, 2008). At the same time, progress in the field has been hindered by the use of inconsistent criteria to identify problem users of the Internet and video games, and/or recruitment methods that may have caused serious sampling bias (Byun et al., 2008). More specifically, Widyanto and Griffiths (2006a) have also noted that most of the screening instruments used (a) have no measure of severity, (b) have no temporal dimension, (c) have a tendency to overestimate the incidence of the problems, and (d) do not consider the context of use. Further, many studies of problematic users have not included additional screening measures of psychopathology, thereby failing to account for the possible influence of comorbid disorders. This has lead to considerable confusion among psychologists regarding the conceptualization and status of technology-based problematic behaviors. Given the lack of consensus whether technology-based "addictions" exist, some researchers have instead used terminology such as "excessive" or "problematic" to denote the harmful use of technology (Yellowlees & Marks, 2007). Problematic Internet and/or video game use refers to persistent and very high levels of involvement in these activities (e.g., browsing websites, online information gathering, downloading or trading files online, online social networking, online video gaming, online shopping, online gambling) that results in detrimental emotional and social consequences for the user (Shapira et al., 2003). Empirical research studies employing this broad definition of problem behavior report that a significant minority of individuals report significant psychological and social problems associated with excessive technology use (Kaltiala-Heino, Lintonen, & Rimpela, 2004; Peters & Malesky, 2008). …

The toxicity of iron to brown trout and effects on the gills: a comparison of two grades of iron sulphate

Abstract: The 96-h LC50 on brown trout Salmo trutta of a commercial iron (III) sulphate liquor, used for treating reservoirs to reduce algal growth, was 28 mg total Fe l−1 (0·05 mg soluble Fe l−1). The 96-h LC50 for analar grade iron (III) sulphate was 47 mg total Fe l−1 (0·24 mg soluble Fe l−1). Lethal and sublethal exposure to both grades of iron resulted in accumulation on the gill, which appears to be the main target for iron toxicity. Greater iron accumulation occurred during exposure to commercial iron sulphate liquor. Physical clogging of gills and gill damage was seen during lethal and sublethal exposure to iron. Gill tissue analysis showed no evidence of iron uptake into gill tissues during lethal or sublethal exposure to iron. Iron did not accumulate in plasma of fish exposed to iron compared to controls. Respiratory disruption due to physical clogging of the gills is suggested as a possible mechanism for iron toxicity.

Space, sanctity and service: the English Cathedral as heterotopia

Abstract: The 43 Anglican Diocesan cathedrals in England attract in excess of 30 million tourist visitors per year, but also function as museums, centres for pilgrimage and foci for the performing arts. This paper examines the complex nature of the experience offered by cathedrals to their visitors, which often generates difficulties associated with sites that may be viewed as interfaces between the sacred and the profane. It also identifies the problems presented by the requirement to earn revenue from visitors (especially by charging admission) when still offering facilities for worship, prayer or meditation. The model adopted is Foucault's concept of sacred space as heterotopia (a ritual space that exists out of time). It is argued that difficulties over admissions charges are not simply straightforward reluctance to pay up, but intrinsically related to the nature of the spiritual experience expected and received by visitors to cathedrals, whether consciously or not.
