Methods of constructing group divisible designs with k = 3 and 4

The paper provides methods of construction of group divisible designs with block sizes three and four through balanced incomplete block and partially balanced incomplete block designs of block sizes 3 and 4. Furthermore, four non-isomorphic solutions are given.     

Effects of physical and mental demands on shoulder muscle fatigue

Mental demands have been associated with increased risk of injuries; however, its influence on muscle fatigability remains unclear. The aim of this study was to investigate the interaction of mental workload and physical workload on muscle fatigability during repetitive shoulder work. Twelve young participants, balanced by gender, performed shoulder abduction exercises until exhaustions at three levels of physical workload (low (5% maximum voluntary contraction (MVC)), moderate (35% MVC), and high (55% MVC)) in the absence and presence of a mental arithmetic test. Endurance time and rate of strength decline were employed as indicators of muscle fatigue. Concurrent physical and mental processing was found to adversely decrease muscle endurance by ~25% at the moderate intensity level. Furthermore, concurrent demands were associated with faster rate of strength decline compared to the control, irrespective of the physical intensity level. Findings from the current study provide evidence of the adverse effects of mental workload on muscle capacity (i.e., endurance and fatigue). It is therefore important to consider potential changes in worker capacity with concurrent physical and cognitive demands before designing work tasks/products.     

A Comparison of the Predictive Validity of Procedures for Analyzing Binary Data

Some approaches for analyzing binary data are briefly described and compared. The results of two empirical investigations in the context of assessing consumer preferences and a simulation study yield some interesting findings. The article concludes with some directions for future research in this area.     

Gender and changing generational relations: Spouse choice in Indonesia

Many Asian societies are undergoing a nuptiality transition that is not only tied integrally to other aspects of family organization, but is also often more complex than standard studies of female age at marriage can reveal. To comprehend some of this complexity, we focus on the patterns of spouse choice for both men and women in central Java. The extent of parental control over mate selection is examined for change over time, gender differences, and likely determinants, including family class, education, premarital work, and residence. It is argued that the current marriage transition in Indonesia reflects both gender and generational hierarchies in the Javanese family system. The analysis is conducted using a multinomial logit model; in general, it yields results strongly supportive of the argument that the determinants of spouse selection differ by gender. The results also show that although there is a dramatic shift towards self-choice marriages, it is occurring within the context of historical and institutional factors specific to Javanese society.     

The Role of Information and Communication Technologies in Addressing Safe Motherhood in South Asia

ABSTRACT

As it is recently recognized in academic and policy circles, limited access to information and limited knowledge are among key factors contributing to worldwide poverty, especially in low developed countries. Consequently, access to “knowledge” has become an integral part of discussions about global development, improvement of societal well-being, and empowerment of women. This article addresses the problem of the limited spread of information about maternal health and available maternal care services across impoverished South Asian countries. Lack of knowledge greatly contributes to underutilization of medical services and available maternal care that leads to high rates of maternal and infant mortality and pregnancy-related complications which, with proper medical care, could be avoided.     

The social accomplishment of music in a symphony orchestra: A phenomenological analysis

The accomplishment of musical performance in a symphony orchestra is analyzed phenomenologically based on participant observation. Musicians rely on the we-relationship, gestural communication, common stock-of-knowledge, melody, and the conductor's hermeneutics to coordinate diverse perceptions and time structures. The self of the musician appears in codings of mistakes and in the orchestral hierarchy. Thelebensvelt of the rehearsal is directed towards its abandonment to the world-of-music.The author appreciates the suggestions of D.L. Wieder, Richard Owsley, Leo D. Papa and two anonymous reviewers forQualitative Sociology.     

Strategic Manufacturing Planning Systems and Their Linkage to Planning System Success

Academics and practitioners alike are focusing more attention on manufacturing strategy after having recognized the important role it plays in shaping the success of industrial firms. Even though research in this area has increased in the last decade, the focus of much of that work has been on the content rather than the process of the manufacturing strategy. Consequently, this study attempts to understand the important elements of the strategic manufacturing planning process and its effectiveness. Borrowing from the extant literature in the fields of strategic management and information systems, we propose a research model that relates strategic manufacturing planning system design to planning system success. Using structured questionnaires, empirical data is collected from over 200 manufacturing executives to test the model hypotheses. Planning process in manufacturing was found to be a bottom‐up approach from a corporate or business perspective, which differs from the top‐down planning process prevalent in strategic information systems planning process. Findings also indicate that greater planning system success in manufacturing is associated with a planning system that combines some “rational” elements (formality, comprehensiveness, control focus, longer horizon) with others that lend adaptability (wider participation and more intense interaction). But the strategic manufacturing planning system is more than just a collection of independent planning characteristics. Instead, it can be viewed as a gestalt planning system whereby planning characteristics move together in affecting overall planning system success.     

Curvilinear relationship between cultural distance and equity participation: An empirical analysis of cross-border acquisitions

We examine the relationship between national cultural distance and equity participation using an analysis of a sample of more than 100,000 cross-border acquisitions from 1976 to 2008. We find that cultural distance has a curvilinear (U shaped) relationship with equity participation: Acquiring firms make large equity acquisitions at both low and high cultural distances and small equity acquisitions at moderate cultural distances. In addition, we find that industry relatedness of acquisitions positively moderates the relationship between cultural distance and equity participation: Acquiring firms take a higher equity stake for a given cultural distance if the acquisitions are in a related industry. Our findings offer important insights into firms' market entry behavior and provide guidelines for managers about entry strategies.
