National policy making in a global economy: The case for U.S. economic planning

In 1980 the Joint Economic Committee completed the Special Study on Economic Change. This 20 volume, 3-year project, was premised on the fact that: ‘fundamental economic, social, political, international and technical conditions have changed, and are still changing markedly’. This suggests that conventional wisdom and established economic tools may not be equal to meeting the challenge of making sound policies in the economic sphere. The so-called laws of economics have not been repealed, but all guiding principles presuppose a certain environment of conditions, customs and practices—and when these change, the implementation of new policies and the modes of adjustment have to change also. This paper examines the problem of devising policy instruments for economic management, identifying the facts of the changing economic environment and the main difficulties facing world economic development.     

On the definition and varieties of attitude and wellbeing

In a paper published in Social Indicators Research in 1975, Levy and Guttman proved the proposition that wellbeing is a special case of attitude. They exploited this result for establishing a certain lawfulness for wellbeing behavior, and built on this for revealing more specialized features of the lawfulness. Five years later in this same journal, Andrews and McKennell published two papers on exactly the same proposition, but without proving it, without building on known relevant lawfulness of attitudinal behavior, and without mentioning (neither positively nor negatively) the Levy-Guttman work. The Andrews-McKennell papers are shown to be a retrogression rather than a scientific advance, being conceptually confused, using inappropriate data analysis, and dealing with arbitrary assumptions which are either untested, untestable or false.     

Properties of a generalized source-to-all-terminal network reliability model with diameter constraints

Given the pervasive nature of computer and communication networks, many paradigms have been used to study their properties and performances. In particular, reliability models based on topological properties can adequately represent the network capacity to survive failures of its components. Classical reliability models are based on the existence of end-to-end paths between network nodes, not taking into account the length of these paths; for many applications, this is inadequate, because the connection will only be established or attain the required quality if the distance between the connecting nodes does not exceed a given value.An alternative topological reliability model is the diameter-constrained reliability of a network; this measure considers not only the underlying topology, but also imposes a bound on the diameter, which is the maximum distance between the nodes of the network. In this work, we study in particular the case where we want to model the connection between a source-vertex s and a set of terminal vertices K (for example, a video multicast application), using a directed graph (digraph) for representing the topology of the network with node set V. If the s,K-diameter is the maximum distance between s and any of vertices of K, the diameter-constrained s,K-terminal reliability of a network G, R_s,K(G,D), is defined as the probability that surviving arcs span a subgraph whose s,K-diameter does not exceed D.One of the tools successfully employed in the study of classical reliability models is the domination of a graph, which was introduced by Satyanarayana and Prabhakar. In this paper we introduce a definition and a full characterization of the domination in the case of the diameter-constrained s,K-terminal reliability when K=V, including the classical source-to-all-terminal reliability domination result as a specific case. Moreover we use these results to present an algorithm for the evaluation of the diameter-constrained s,V-terminal reliability R_s,V(G,D).     

Mein(nach-wie-vor-schöner)Prof.de

Tobias Wolbring argues in his replica to our article Mein(schöner)Prof.de (issue 4/2009 of this journal) that the presented empirical analyses would be problematic in several respects. He claims our sample was selective, criticizes the lacking control of relevant confounding variables and our statistical model building. In this response we consider Wolbring’s criticism in detail. We believe we can prove that his points of criticism do not hold after a close investigation. In particular, we think our central substantial conclusions can be maintained.     

An examination of associations among manager-boss gender,self-awareness,and managerial derailment

Using the data of managers in the United States (N = 42,792), United Kingdom (N = 3,797), and China (N = 1,893), we examined the associations among manager-boss gender combinations, self-awareness and the managerial derailment potential. First, the study demonstrated an association between manager-boss gender combinations and managerial self-awareness, even though the specific gender joint effects were not consistent among the three countries. Second, both self-awareness and manager-boss gender combinations contributed to explaining additional variance of managerial derailment potential. Consistently across three countries, overestimators were more likely to derail than the managers who were in touch with their bosses. In terms of gender effects, compared to male managers, female managers with male bosses were more likely to derail. These results imply that, to achieve high levels of self-awareness and provide accurate prediction of managerial derailment potential, organizational scholars and practitioners must consider both the gender of both managers and their bosses.
