Differentiating transformational and non-transformational leaders on the basis of neurological imaging

The purpose of this study was to evaluate the viability of using neurological imaging to classify transformational leaders, versus non-transformational leaders, as identified through existing psychometric methods. Specifically, power spectral analysis measures based on electroencephalograms (EEG) were used to develop and validate a discriminant function that can classify individuals according to their transformational leadership behavior. Resting, eyes closed EEG was recorded from 19 scalp locations for 200 civilian and military leaders. We also assessed follower or peer perceptions of transformational leadership through the use of the Multifactor Leadership Questionnaire (MLQ). Our discriminant analysis, which involved a two-step, neural variable reduction and selection process, was 92.5% accurate in its classification of leaders. Patterns in the spectral measures of the brain of leaders, including activity and network dynamic metrics, are discussed as potential correlates of transformational leadership behavior. The current work provides a better understanding of the latent and dynamic neurological mechanisms that may underpin the transformational leadership qualities of individuals.     

Prevalence of sarcopenia and its association with functional and nutritional status among male residents in a nursing home in Turkey

Introduction The Aging Male Symptoms' (AMS) scale was designed as a health-related quality of life (QoL) scale and standardized as a self-administered scale, first, to assess symptoms of aging (independent from those which are disease-related) between groups of males under different conditions, second, to evaluate the severity of symptoms/QoL over time, and, third, to measure changes pre- and post-androgen replacement therapy. The scale is in widespread use (17 languages currently available) and a recent review of methodological data documented good psychometric characteristics and ability as a clinical utility. This paper describes test characteristics of the AMS (positive and negative predictive values), taking two internationally established and published screening scales for androgen deficiency as the available standard.

Method A sample of 150 German males aged 40–69 years completed the AMS scale and two screening scales for androgen deficiency: the ADAM scale of Morley and colleagues and the screener of Smith and colleagues. The technique of a computer-assisted telephone interview was applied.

Result The comparison of the AMS with the two screening instruments for androgen deficiency showed sufficiently good compatibility despite conceptual differences. The AMS scale sufficiently predicted the results of the two screening instruments. A positive predictive value of 92% and a negative predictive value of 50% were found regarding the ADAM scale. The respective figures regarding Smith's screener were 65% and 49% for positive and negative predictive values, respectively.

Conclusion The AMS scale obviously measures a similar phenomenon as the two established and widely used screeners for androgen deficiency, although it was not developed as a screening instrument.     

STRATEGIC COMPLEMENTARITY SLOWS MACROECONOMIC ADJUSTMENT TO TEMPORARY SHOCKS

A number of studies have employed strategic complementarity to show that many features of the Keynesian framework can be captured in models consistent with the microfoundations approach. We argue that strategic complementarity is an important factor in understanding why an economy may exhibit a slow return to steady-state behavior after a temporary shock. That is, given any of a variety of factors which would cause temporary shocks to have long-term effects, the speed with which the economy returns to steady-state behavior after a temporary shock is negatively related to the degree of strategic complementarity in the environment.     

Cumulative influence: the case of political settlements research in British policy

The concept of the political settlement has risen to occupy a central place in British policy toward conflict-affected and fragile states. Yet, at around the turn of the millennium, the term was barely mentioned in official circles and the so-called ‘good governance’ approach held sway as the dominant operational mode. So, how had this transformation in policy approach come about and what was the role of research? In this article, we demonstrate that research played a central role in influencing the rhetoric of policymakers through a process we term ‘cumulative influence’. Indeed, the subject of political settlements represents an excellent case study for understanding the dynamics of research utilisation. It allows us to build on existing models and suggest useful ways forward in this important area of public policy analysis.     

What's an Oscar worth?

This article examines the impact of an Academy Award nomination and award for best picture, best actor/actress, and best supporting actor/actress on a film's (i) market share of theaters, (ii) average revenue per screen, and (iii) its probability of survival. The model is estimated using weekly box-office data for a matched sample of nominated and non-nominated films. The results indicate substantial financial benefits for a nomination and award for best picture and best actor/actress. The structure of rewards is consistent with that found in two-stage, single-elimination tournaments.     

Practice Change in Child Welfare: The Interface of Training and Social Work Education

This article examines perceptions of the relationship between professional education and workplace training among a select group of public child welfare employees who pursued graduate social work education during a period of major practice change at their agency. Focus groups were conducted with representative members of graduating cohorts as students completed their studies to explore the connections and distinctions between their professional education and the workplace training that introduced case practice reform. Experienced caseworkers, supervisors, and management-level staff, study participants were well situated to contemplate the changes in process at their agency. They offered insights into the progress of reform and the challenges of sustaining change as well as their roles as professional social workers in carrying reforms forward.     

The mean of the conditional,truncated multinormal distribution

An expression is derived for the mean of the conditional, truncated multinormal distribution in the general case, and for the situation where the conditioning variates have iden¬tical correlation. This equicorrelated case occurs in some models of duration and in panel data. An example is taken from economics, where a cross section of firms consider the adoption of several technological innovations. The results of the paper are used to estimate the firm-specific.     

Alternative forms of charismatic leadership in the integration of mergers and acquisitions

It is becoming increasingly clear that post-merger and acquisition (M&A) performance, especially in terms of achieving the integration of merging firms, is strongly affected by organizational factors, such as leadership. This paper presents a theoretical model showing how alternative forms of charismatic leadership can be relevant to the implementation of M&As. A unique aspect of our conceptualization is that we recognize the distinction between charismatic leaders with more of a personalized versus socialized power motive, the behaviors emanating from each respective type, and likelihood of resulting effects on the post-combination organization of an M&A. We also propose that personalized charisma will result in an absorption strategy and accompanying stress, resistance to change, and turnover that vary in degree between acquiring and acquired firms. Conversely, socialized charisma will result in collaborative vision-formation and decision-making processes that will ultimately achieve transformation in both of the combining firms. We further argue that absorption strategies can result in effective integration of the target firm into the acquiring firm when the pre-merger condition of the former is unfavorable.     

Leadership and organizational learning: A multiple levels perspective

We review theoretical and empirical work relevant to the nexus of leadership with organizational learning. We build on the classic distinction between exploration and exploitation and the 4I framework of organizational learning [Crossan, M. M., Lane, H. W., & White, R. E. (1999). An organizational learning framework: From intuition to institution. Academy of Management Review, 24, 522–537.] to present previous research and offer research directions linking leadership constructs and processes of organizational learning at different levels of analysis. For each of these links, we discuss the mediating effect of organizational context and suggest future research directions. This review is integrated using a model and propositions that depict the role of leaders with regard to new and existing learning.
