Constructing useful theory: The case of Six Sigma

Organizational practices related to Six Sigma are believed to have resulted in improved organizational outcomes. The academic community, however, continues to lack understanding of the constructs and causal relationships underlying Six Sigma. Hence, discussion of Six Sigma is buffeted by anecdotal experience reported from practice. We evaluate Six Sigma through the lens of literature on theory development to explain why the Six Sigma constructs, assumptions, and causal relationships are inconsistent with theory development principles.

Toward a unified theory of consumer acceptance technology

In the last few decades, scholars and practitioners have increasingly tried to understand the factors that influence technology acceptance. Theories and models developed by scholars have tended to focus on the role of cognition and have rarely included affect. The few studies that have incorporated affect have tended to measure a single emotion rather than modeling it comprehensively. This research addresses that inadequacy in our understanding of technology adoption by merging two previously unrelated models: TAM (the Technology Acceptance Model) and PAD (the Pleasure, Arousal, and Dominance paradigm of affect). This study also examines an enhanced view of cognition. The product of this unified theoretical framework is referred to as the Consumer Acceptance of Technology (CAT) model. The results of a test using structural equation modeling provide empirical support for the model. Overall, the CAT model explains over 50% of the variance in consumer adoption intentions, a considerable increase compared to TAM. These findings suggest that substantial improvement in the prediction of technology adoption decisions is possible by use of this model with its integration of affect and cognition. © 2007 Wiley Periodicals, Inc.     

Bicycle-related injuries: Injury,hazard, and risk patterns

Abstract

This paper provides the results of a U.S. Consumer Product Safety Commission (CPSC) study to determine the circumstances involved in bicycle-related injuries treated in U.S. hospital emergency rooms. It also includes information from a CPSC exposure survey of the U.S. population of bicycle users and their patterns of bicycle and helmet use. Together, these data were used to identify and evaluate risk factors currently associated with bicycle use in the United States

Risk models identified factors specifically associated with injuries to children and to adults. Children were at particular risk of injury, and appeared to be especially vulnerable to head injury. In addition, the risk of injury for children was significantly increased when riding in non-daylight conditions. For both adults and children, there was a higher risk of injury on streets than in such areas as bike paths or unpaved surfaces. While some problems associated with bicycle assembly, operation, and maintenance were observed, the data did not suggest that any mechanical remedy is likely to reduce injuries substantially.     

Presumptions of linearity and faith in the power of centralised decision‐making: two challenges to the efficient management of environmental water in Australia

Water policy in the Murray‐Darling Basin continues to be dominated by the trade‐offs between agricultural and environmental interests. This has recently been played out with the acrimonious debate that circumscribed the release of the Guide to the Murray‐Darling Basin Plan. In this paper, we argue that too much emphasis has been placed on the volume of held water as an indicator of environmental benefit. We also contend that there is an attendant presumption of linearity in the relationship between volumes of held water and environmental benefit which could lead to perverse outcomes. A second problem is that there is too much enthusiasm for contemplating the solutions to water management problems as residing primarily at the federal level of government. These factors stand to ultimately limit the efficient delivery of environmental objectives.     

Rebounding from Corruption: Perceptions of Ethics Program Effectiveness in a Public Sector Organization

We examine the perceived importance of three organizational preconditions (awareness of formal ethics codes, decision-making techniques, and availability of resources) theorized to be critical for ethics program effectiveness. In addition, we examine the importance of ethical leadership and congruence between formal ethics codes and informal ethical norms in influencing employee perceptions. Participants (n=418) from a large southern California government agency completed a survey on the perceived effectiveness of the organization’s ethics program. Results suggest that employee perceptions of organizational preconditions, ethical leadership and informal ethical norms were related to perceptions of ethics program effectiveness. Based on these findings, organizations should evaluate the presence (or absence) of essential preconditions and take steps to ensure that leaders model espoused organizational values to foster perceptions of effective ethics programs.Kathie L.

Impact of Funding Targeted Pre-school Interventions on School Readiness: Evidence from the Netherlands

We analyze the effectiveness of the early childhood programme (ECP) in the Netherlands. The programme is designed for 2.5–4 year olds from disadvantaged backgrounds. 37 municipalities received an additional subsidy to expand ECP programmes, which allows us to analyze the effects of the programme within a difference-in-difference-in-differences framework. Most children first enroll in primary schools at age 4 in the Netherlands, but pupils begin to learn reading and mathematics in grade 3 at age 6. We use grade repetition constructed from school registry data from 2008 to 2015 in the first two grades as an indicator of school readiness. Our results show significantly lower grade repetition rates for targeted boys who are in regions that receive the subsidy. Grade repetition drops by 0.8–1.8 percentage points from a mean of 10.5% for the disadvantaged group targeted by the programme.     

Partners in protest: parents,unions and anti‐academy campaigns

An analytical framework has been developed in order to enhance our ability to interrogate and understand the critical factors for successful union–community coalitions. The framework is then tested on a single case study, a campaign run by trade unions, parents and community groups engaged in opposing academisation of their community school. The framework helps structure analysis and aids evaluation of the impact of activists' choices on campaign outcomes.
