Transmuting performance on manufacturing dimensions into business performance: An exploratory analysis of efficiency using DEA

This research examines efficiency in the transformation of performance on manufacturing competitive dimensions into business performance in the automotive supplier industry. Specifically, the study explores efficiency produced from data envelopment analysis (DEA) using cost, quality, time, flexibility and innovativeness performance as inputs and return on investment (ROI) and return on assets (ROA) as outputs. First tier suppliers to the 'Big 3' in North America were sampled. The 51 suppliers were categorized into three groups (high, medium and low) based on their efficiency. No significant group differences in quality, time, flexibility and innovativeness performance were found, but a significant difference does exist for cost. The results were further investigated by testing between-group differences for various cost reduction programmes, thereby identifying the levers and benchmarks for improving low efficiency firms.     

The effects of product modularity on launch speed

Extant literature suggests that product modularity positively and directly impacts the timeliness and frequency of new products as well as manufacturing performance, particularly flexibility. Little is known about the nature of these relationships, however, since few empirical studies have been done. Important questions remain unanswered including whether the effect of modularity on launch speed is direct or indirect, and what role other constructs might play. This study explores these issues by examining the effects of product modularity on launch speed within a holistic framework that considers the roles of product platforms and manufacturing flexibility. Drawing upon dynamic capabilities theory in the resource-based view, the model depicts product modularity as antecedent to product platforms, product platforms as antecedent to manufacturing flexibility and manufacturing flexibility as antecedent to launch speed. The model is strongly supported by an analysis of 93 manufacturers. Results reveal a positive effect of product modularity on launch speed, but it is delivered through the mediating effects of product platforms and manufacturing flexibility. In contrast to earlier work, the findings show modularity alone is an insufficient condition for the timely and frequent introduction of new products. Rather, launch speed is engendered by a ‘gestalt’ of dynamic capabilities.     

Spandrels in the consulting room.

The author states that D. M. Buss et al (see record 1998-01669-001) instead of embracing the complexity of evolutionary theory, coopted S. J. Gould's (see S. J. Gould and E. S. Vrba, 1982) notion of exaptation for their own purposes. The author takes issue with criticism by Buss et al that Gould did not reduce language, religion, and so on to clear adaptive stories, while revealing their own reductionist agenda regarding their explanation for parental care. He also discusses the mention by Buss et al of constraints on design, but asserts that discussion of this concept, as applied to the evolution of human behavior, did not take into account intervening human neurophysiology.

A preliminary examination of the relationship between exposure to community violence and academic functioning.

Provides a preliminary examination of the relationship between exposure to community violence and academic functioning in a group of 45 African American children (aged 11–14 yrs) living in an impoverished urban environment. In addition, the role of family achievement expectations and religion, 2 previously identified family compensatory factors related to academic resilience, were evaluated as moderators of the relationship between community violence and academic functioning. Ss completed questionnaires about the variables mentioned above. Results suggest that exposure to community violence had a weak relationship with academic functioning in general, but that relationship was intensified under certain circumstances. Significant interactions between exposure to community violence, and both family achievement orientation and religious emphasis suggest that exposure to community violence may alter the role of previously identified compensatory factors. Children who perceived very high achievement expectations and a very strong moral-religious emphasis were most at risk for poor academic functioning as exposure to community violence increased, although children from these types of families displayed the highest academic functioning at lower levels of community violence exposure.
