Can a leader be seen as too ethical? The curvilinear effects of ethical leadership

Ethical leadership predicts important organizational outcomes such as decreased deviant and increased organizational citizenship behavior (OCB). We argued that due to the distinct nature of these two types of employee behaviors, ethical leadership decreases deviance in a linear manner (i.e., more ethical leadership leading to less deviance), but we expected ethical leadership to reveal a curvilinear relationship with respect to OCB. Specifically, we expected that, at lower levels, ethical leadership promotes OCB. However, at high levels, ethical leadership should lead to a decrease in these behaviors. We also examined a mechanism that explains this curvilinear pattern, that is, followers' perceptions of moral reproach. Our predictions were supported in three organizational field studies and an experiment. These findings offer a better understanding of the processes that underlie the workings of ethical leadership. They also imply a dilemma for organizations in which they face the choice between limiting deviant employee behavior and promoting OCB.     

Umbrella for research into Human Resource Development (HRD)

This paper explores Thailand's ‘sufficiency economy’ (SE) philosophy and its impact on human resource development (HRD). The paper highlights the current attempts to achieve sustainable development, especially after the economic crisis of 1997. The philosophy introduces a great shift of conceptual thinking on the general development and administration in the country. This paper examines the importance of the SE philosophy and discusses its impact on HRD in Thailand at different levels of the society.     

Clustering with or without the approximation

We study algorithms for clustering data that were recently proposed by Balcan et al. (SODA’09: 19th Annual ACM-SIAM Symposium on Discrete Algorithms, pp. 1068–1077, 2009a) and that have already given rise to several follow-up papers. The input for the clustering problem consists of points in a metric space and a number k, specifying the desired number of clusters. The algorithms find a clustering that is provably close to a target clustering, provided that the instance has the “(1+α,ε)-property”, which means that the instance is such that all solutions to the k-median problem for which the objective value is at most (1+α) times the optimal objective value correspond to clusterings that misclassify at most an ε fraction of the points with respect to the target clustering. We investigate the theoretical and practical implications of their results. Our main contributions are as follows. First, we show that instances that have the (1+α,ε)-property and for which, additionally, the clusters in the target clustering are large, are easier than general instances: the algorithm proposed in Balcan et al. (SODA’09: 19th Annual ACM-SIAM Symposium on Discrete Algorithms, pp. 1068–1077, 2009a) is a constant factor approximation algorithm with an approximation guarantee that is better than the known hardness of approximation for general instances. Further, we show that it is NP-hard to check if an instance satisfies the (1+α,ε)-property for a given (α,ε); the algorithms in Balcan et al. (SODA’09: 19th Annual ACM-SIAM Symposium on Discrete Algorithms, pp. 1068–1077, 2009a) need such α and ε as input parameters, however. We propose ways to use their algorithms even if we do not know values of α and ε for which the assumption holds. Finally, we implement these methods and other popular methods, and test them on real world data sets. We find that on these data sets there are no α and ε so that the dataset has both (1+α,ε)-property and sufficiently large clusters in the target solution. For the general case where there are no assumptions about the cluster sizes, we show that on our data sets the performance guarantee proved by Balcan et a. (SODA’09: 19th Annual ACM-SIAM Symposium on Discrete Algorithms, pp. 1068–1077, 2009a) is meaningless for the values of α,ε for which the data set has the (1+α,ε)-property. The algorithm nonetheless gives reasonable results, although it is outperformed by other methods.     

Cohort Quantum as a Function of Time-dependent Period Quantum for Non-repeatable Events

The paper discusses translation formulae for time-dependent cohort and period quantum for non-repeatable events. Cohort quantum expressions are investigated for two cases: one in which period quantum, and another in which the sum of the period rates decreases linearly with time. In both cases the assumption is that period tempo does not change. Sufficient conditions are given for the situation in which the cohort quantum simply equals the period quantum measured at the time when the cohort reaches the mean age of the period schedule of age-specific rates, given that the period rate sum is a polynomial function of time. The paper takes up an issue which was unresolved in the article ‘Translation formulae for non-repeatable events’, which appeared in the July 1994 issue of Population Studies.     

Household and Context Determinants of Child Labor in 221 Districts of 18 Developing Countries

We develop a new theoretical framework that explains the engagement in child labor of children in developing countries. This framework distinguishes three levels (household, district and nation) and three groups of explanatory variables: Resources, Structure and Culture. Each of the three groups refers to another strand of the literature; economics, sociology and anthropology. The framework is tested by applying multilevel analysis on data for 239,120 children living in 221 districts of 18 developing countries. This approach allows us to simultaneously investigate effects of household and context factors. At the household level, we find that resources and structural characteristics influence child labor, whereas cultural characteristics have no effect. With regard to context factors, we find that children work more in rural areas, especially if there are more unskilled manual jobs, and in more traditional urban areas. In more developed regions, girls tend to work significantly less.     

Political Regime and Human Capital: A Cross-Country Analysis

We examine the relationship between different dimensions of the political regime in place and human capital using a two-step structural equation model. In the first step, we employ factor analysis on 16 human capital indicators to construct two new human capital measures (basic and advanced human capital). In the second step, we estimate the impact of our political variables on human capital, using a cross-sectional structural model for some 100 countries. We conclude that democracy is positively related to basic human capital, while regime instability has a negative link with basic human capital. Governance has a positive relationship with advanced human capital, while government instability has a negative link with advanced human capital. Finally, we also find an indirect positive effect of governance and democracy on both types of human capital through their effect on income.     

A multi-city epidemic model

Some analytical results are given for a model that describes the propagation of a disease in a population of individuals who travel between n cities. The model is formulated as a system of 2n 2 ordinary differential equations, with terms accounting for disease transmission, recovery, birth, death, and travel between cities. The mobility component is represented as a directed graph with cities as vertices and arcs determined by outgoing (or return) travel. An explicit formula that can be used to compute the basic reproduction number, {\cal R}_0 , is obtained, and explicit bounds on {\cal R}_0 are determined in the case of homogeneous contacts between individuals within each city. Numerical simulations indicate that {\cal R}_0 is a sharp threshold, with the disease dying out if {\cal R}_0 1 .     

Interpreting Child Sexual Abuse: Empathy and Offense-Supportive Cognitions among Child Sex Offenders

Researchers have suggested that child sex offenders hold distorted views on social interactions with children. Misinterpreting children’s behavior and intentions could lead to sexually abusive behavior toward children. It is further suggested that the interpretation process is influenced by offenders’ offense-supportive cognitions and levels of empathy. To examine the relationships between these three concepts, 47 contact offenders completed self-reports on offense-supportive cognitions and empathy. Vignettes were developed to assess the extent to which offenders attributed responsibility, benefit, and complicity to children in hypothetical child molestation incidents. This study showed that cognitions that justify sexual offending against children seem to diminish the threshold for sexual assault by assigning more cooperation and willingness of the victim in a child molestation incident.     

Cosmopolitan Justice and the Globalization of Capitalism: The UNDP and ILO Proposals

Abstract

Recently several proposals for more effective, democratic and just forms of global governance have been put forward. In this paper I compare the proposals by the United Nations Development Programme, the International Labour Organization and cosmopolitan democrats like David Held. I assess to what extent they are in accordance with cosmopolitan views of global justice and I critically evaluate to what extent they may be feasible interim steps. The conclusion is that even though some proposals are more radical than others, they all leave in place the current institutions of an international order based on sovereign nation-states, global capitalism and its resulting inequality, and models of development as based on maximizing economic growth. If cosmopolis is to replace empire in the international system, then these certainties need to be open for discussion, too.
