Critique and Review of Leader-Member Exchange Theory: Issues of Agreement, Consensus, and Excellence

The relationship quality that develops between leaders and those designated as followers is of longstanding interest to researchers and practitioners. The purpose of the present article is to review the more recent developments in the field of leader-member exchange (LMX) theory to identify specific issues related to leader-member agreement and follower consensus that have potentially important theoretical and practical implications. We introduce the concept of LMX excellence, which involves high-quality LMX, high leader-member agreement as well as high group consensus in LMX quality. We outline how leaders and followers' behaviour as well as context can enhance or hinder the development of LMX excellence and conclude with an overview of the practical and theoretical implications as well as future research needs

Making things happen : a model of proactive motivation

Being proactive is about making things happen, anticipating and preventing problems, and seizing opportunities. It involves self-initiated efforts to bring about change in the work environment and/or oneself to achieve a different future. The authors develop existing perspectives on this topic by identifying proactivity as a goal-driven process involving both the setting of a proactive goal (proactive goal generation) and striving to achieve that proactive goal (proactive goal striving). The authors identify a range of proactive goals that individuals can pursue in organizations. These vary on two dimensions: the future they aim to bring about (achieving a better personal fit within one’s work environment, improving the organization’s internal functioning, or enhancing the organization’s strategic fit with its environment) and whether the self or situation is being changed. The authors then identify “can do,” “reason to,” and “energized to” motivational states that prompt proactive goal generation and sustain goal striving. Can do motivation arises from perceptions of self-efficacy, control, and (low) cost. Reason to motivation relates to why someone is proactive, including reasons flowing from intrinsic, integrated, and identified motivation. Energized to motivation refers to activated positive affective states that prompt proactive goal processes. The authors suggest more distal antecedents, including individual differences (e.g., personality, values, knowledge and ability) as well as contextual variations in leadership, work design, and interpersonal climate, that influence the proactive motivational states and thereby boost or inhibit proactive goal processes. Finally, the authors summarize priorities for future researc

Psychological resilience in sport performers: a review of stressors and protective factors

Psychological resilience is important in sport because athletes must utilize and optimize a range of mental qualities to withstand the pressures that they experience. In this paper, we discuss psychological resilience in sport performers via a review of the stressors athletes encounter and the protective factors that help them withstand these demands. It is hoped that synthesizing what is known in these areas will help researchers gain a deeper profundity of resilience in sport, and also provide a rigorous and robust foundation for the development of a sport-specific measure of resilience. With these points in mind, we divided the narrative into two main sections. In the first section, we review the different types of stressors encountered by sport performers under three main categories: competitive, organizational, and personal. Based on our recent research examining psychological resilience in Olympics champions (Fletcher & Sarkar, 2012), in the second section we discuss the five main families of psychological factors (viz. positive personality, motivation, confidence, focus, perceived social support) that protect the best athletes from the potential negative effect of stressors. It is anticipated that this review will help sport psychology researchers examine the interplay between stressors and protective factors which will, in turn, focus the analytical lens on the processes underlying psychological resilience in athletes

Representational predicaments for employees: Their impact on perceptions of supervisors\u27 individualized consideration and on employee job satisfaction

A representational predicament for a subordinate vis-à-vis his or her immediate superior involves perceptual incongruence with the superior about the subordinate\u27s work or work context, with unfavourable implications for the employee. An instrument to measure the incidence of two types of representational predicament, being neglected and negative slanting, was developed and then validated through an initial survey of 327 employees. A subsequent substantive survey with a fresh sample of 330 employees largely supported a conceptual model linking being neglected and negative slanting to perceptions of low individualized consideration by superiors and to low overall job satisfaction. The respondents in both surveys were all Hong Kong Chinese. Two case examples drawn from qualitative interviews illustrate and support the conceptual model. Based on the research findings, we recommend some practical exercises to use in training interventions with leaders and subordinates. © 2013 Copyright Taylor and Francis Group, LLC

Quality of life predictors in informal caregivers of seniors with a functional performance deficit – an example of home care in Poland

Barbara Ślusarska, Agnieszka Bartoszek, Katarzyna Kocka, Alina Deluga, Agnieszka Chrzan-Rodak, Grzegorz NowickiDepartment of Family Medicine and Community Nursing, Faculty of Health Sciences, Medical University of Lublin, Lublin, PolandBackground: There is insufficient research into informal caregivers’ quality of life (QoL) in Poland. The purpose of this work is to study predictors that considerably affect QoL of informal caregivers (IC) providing home care for seniors with chronic diseases and a functional performance deficit.Materials and methods: In the cross-sectional research design, ICs were randomly chosen among the geriatric population receiving care in 5 primary health care settings. The WHOQoL-AGE questionnaire was used to assess QoL of ICs (n=138). The Barthel scale and Polish version of the Abbreviated Mental Test Score (AMTS) were applied to assess individuals with chronic diseases and functional and mental performance deficits (n=138). The Geriatric Depression Scale Short Form (GDS-SF) was used to measure the extent of risk of depressive symptoms in care-receivers. A hierarchical regression analysis was carried out to determine predictors of caregivers’ QoL.Results: Mean values in the group of seniors provided with home care were as follows: the Barthel scale M=43.20, SD=27.06, the AMTS M=7.78 (SD=1.65), and the GDS-SF M=7.34 (SD=3.10). QoL of ICs (the WHOQoL-AGE) was M=70.14 (SD=15.31). Significant predictors of caregivers’ QoL turned out to be support in care given by others β =0.605, p<0.001, experience in care β =–0.220; p<0.001, caregivers’ health self-assessment β =0.174, p<0.001, and depressive disorders in care-receivers GDS β = −0.178, p<0.001.Conclusions: The QoL of ICs who provide care for individuals with chronic diseases and a functional performance deficit improves with an increase in the support they receive from others, their higher health self-assessment, and greater experience in care. An increase in depressive symptoms in care-receivers determines a lower level of caregivers’ QoL.Keywords: predictors, informal caregivers, quality of life, home care, functional performance deficit, patients with chronic disease

Metal site determination in doped V 2O 5 arg-like cathodes for lithium battery

Vanadium pentoxide materials prepared through sol-gel processes (xerogel, aerogel and aerogel-like) act as excellent intercalation hosts for lithium or polyvalent cations. Important characteristics are retained when the material is modified by reaction with a selected amount of dopant metal (copper, nickel, zinc, aluminum). The electrochemical performance of the materials has been found to be excellent. X-ray Absorption Spectroscopy (XAS) has been used to probe the local structure of the selected atom sites. The strategy in determining the local structure will be discussed both for pristine and doped materials. The doped samples have been analyzed at the vanadium K-edge as well as at the dopant metal K-edge. The presence of two metals gives two independent absorption signals, even if we are investigating the same compound, for this reason the reliability of the analysis is enhanced
