What makes leadership,leadership? Using self-expansion theory to integrate traditional and contemporary approaches

Numerous traditional theories and paradigms of leadership purport to describe what leadership is. It is difficult to reconcile these traditional approaches, however, if each one alone, independent of the others, is viewed as capturing the actual identity of leadership. In this article, we take an integrative view of traditional approaches to leadership. To do so, we first identify some underlying ideas common to them. Next, we explain how these underlying ideas lead us to a fundamental theory about close relationships—that is, self-expansion theory, which refers to a psychological process in which an individual incorporates another into the self (Aron & Aron, 1986). We then review the traditional leadership theories to explore whether these theories may be linked through self-expansion theory and whether self-expansion may help to explain why boundary conditions have been discovered for all of them. In this process, we explore whether traditional approaches to leadership might also be linked with more contemporary approaches through self-expansion theory. Finally, we discuss the implications for future research and professional practice of the integration of traditional approaches to leadership.     

Technological Diversification and Organizational Divisionalization: The Moderating Role of Complementary Assets

This study uses data on 582 electronics and information technology firms in Taiwan for the period 1997–2005 to investigate the hypothesis that technological diversification increases the extent of organizational divisionalization under firm growth. This study applies competence‐based theory to argue that firms spread the technological competence base to achieve firm growth. However, in the face of firm growth, managers of multi‐technology firms often utilize a multi‐division structure to manage their various technologies based on their operating characteristics or needs. Furthermore, the findings of this study indicate that complementary assets moderate the negative relationship between technological diversification and organizational divisionalization. For firms with specialized complementary assets, multi‐technology firms may be observed to consolidate related‐technology activities into fewer divisions, facilitating the utilization of these complementary assets in conjunction with other divisions.     

A Comparison of Regulatory Implications of Traditional and Exact Two-Stage Dose–Response Models

We compare the regulatory implications of applying the traditional (linearized) and exact two-stage dose–response models to animal carcinogenic data. We analyze dose–response data from six studies, representing five different substances, and we determine the goodness-of-fit of each model as well as the 95% confidence lower limit of the dose corresponding to a target excess risk of 10^–5 (the target risk dose TRD). For the two concave datasets, we find that the exact model gives a substantially better fit to the data than the traditional model, and that the exact model gives a TRD that is an order of magnitude lower than that given by the traditional model. In the other cases, the exact model gives a fit equivalent to or better than the traditional model. We also show that although the exact two-stage model may exhibit dose–response concavity at moderate dose levels, it is always linear or sublinear, and never supralinear, in the low-dose limit. Because regulatory concern is almost always confined to the low-dose region extrapolation, supralinear behavior seems not to be of regulatory concern in the exact two-stage model. Finally, we find that when performing this low-dose extrapolation in cases of dose–response concavity, extrapolating the model fit leads to a more conservative TRD than taking a linear extrapolation from 10% excess risk. We conclude with a set of recommendations.     

How Do Disaster Characteristics Influence Risk Perception?

The main purpose of this study is to examine how risk perception is influenced by the type of disaster (flood or landslide) and victim characteristics. The data reported here are based on the National Risk Perception Survey (NRPS) that was administered for the victims and the general public in Taiwan in 2004. In that year, many towns in Taiwan were seriously affected by floods and landslides, resulting in huge economic losses and fatalities. The primary findings are: (1) the victims and the general public are concerned about the different potential hazards that might affect their residential area, (2) the negative associations between the sense of controllability and the perceived impact is high for landslide victims, but not for flood victims, and (3) disaster type, gender, and previously experienced disasters are good predictors of victims' attitudes toward natural disasters.     

Social policy in Hong Kong: From British colony to Special Administrative Region of China

This paper discusses the preservation and change of social policy in Hong Kong in the process of its development from a British colony to a Special Administrative Region of China (SAR). It is argued by the authors that the role and strategy of the colonial government in social policy and social welfare seem to have been largely preserved by the new SAR government which advocates for a new vision for social development. It is also argued that without a democratic mandate, the SAR government continues to rely on stimulating economic output as a primary means to gain legitimation, while social policy and social welfare remain to be subordinated to economic growth. Traditional Chinese values continue to be upheld by the SAR government not only as a means to contain social welfare cost, but also as an instrument to strengthen social control. What is different between the colonial and the SAR regimes is perhaps the increasingly strategic position of Hong Kong as a window of China to the global economy.     

Organization and delivery of long-term care in Taiwan

Taiwan reached the World Health Organization (WHO) benchmark of 7% aged 65 and over for defining an aging population only as recently as 1993. With this proportion projected to double to 14% by 2020, Taiwan faces a rapid increase in need for long-term care. This article presents an account of the current service delivery system, which is divided between health and social affairs administrations, with a substantial role also taken by the Veteran Administration, and growing provision of facilities that operate outside the government-registered system. While a basic level of both institutional and community care services has developed, they are not organized into an integrated service system. Problems arising from the divisions and overlaps in responsibility are identified in relation to competition for resources, differences in regulation and eligibility, funding arrangements and misallocation of resources, and divergent views about the philosophical basis of long-term care. Other aspects of services fall under each jurisdiction, but there is also some overlap. A case study of Taiwan's second largest city, Kaohsiung City, reports the outcomes of these divisions as a thin spread of a range of services rather than a coordinated service network. Several planning exercises have been undertaken in recent years to address these problems, and although at an early stage of implementation, the outcomes of these plans are seen as shaping the future directions of long-term care in Taiwan.     

A Meta-Analysis of the Relationship Between Spirituality and Quality of Life

The relationship between spirituality and various dimensions of health and quality of life has been extensively examined during the past decade. Though several literature reviews have been conducted in an attempt to synthesize research findings pertaining to the relationship between spirituality and health, a meta-analysis of studies examining spirituality in relation to quality of life has not been identified. The present study was designed to: (a) determine whether there is empirical support for a relationship between spirituality and quality of life, (b) provide an estimate of the strength of this relationship, and (c) examine potential moderating variables affecting this relationship. The research design followed accepted methods for quantitative meta-synthesis. Potential moderating effects of several methodological differences and sample characteristics were examined using meta-analytic approaches with multivariate linear regression and analysis of variance. An extensive multidisciplinary literature search resulted in 3,040 published reports that were manually screened according to pre-established selection criteria. Subsequent to the selection process, 62 primary effect sizes from 51 studies were included in the final analysis. A random effects model of the bivariate correlation between spirituality and quality of life resulted in a moderate effect size (r = 0.34, 95% CI: 0.28–0.40), thereby providing support for the theoretical framework underlying the study wherein spirituality was depicted as a unique concept that stands in relationship to quality of life. Subsequent regression analyses indicated that differences among operational definitions of spirituality and quality of life were associated with the variability in estimates of the magnitude of the relationship (R² = 0.27). Other potential moderators, such as age, gender, ethnicity, religious affiliation and sampling method were examined but the findings pertaining to these variables were inconclusive because of limitations associated with the sample of primary studies. The implications of this study are mostly theoretical in nature and raise questions about the commonly assumed multidimensional conceptualization of quality of life.     

Price,Rebate, and Returns Supply Contracts for Coordinating Supply Chains with Price‐Dependent Demands

Channel rebates and returns policies are common mechanisms for manufacturers to entice retailers to increase their order quantities and sales ultimately. However, when the underlying demand depends on the retail price, it has been known that channel coordination cannot be achieved if only one of these mechanisms is deployed. In this article, we show that a policy that combines the use of wholesale price, channel rebate, and returns can coordinate a channel with both additive and multiplicative price‐dependent demands. In addition to determining the sufficient conditions for the contract parameters associated with the equilibrium policy, we show that multiple equilibrium policies for channel coordination exist. We further explore how the equilibrium policy can be adjusted to achieve Pareto improvement. Other issues such as the maximum amount of expected profit that the manufacturer can share under the coordinated channel, the structural properties of the contracts under both the additive and multiplicative price‐dependent demand functions are also discussed.
