Statistics for Quality and Productivity: A New Graduate-Level Statistics Course

The growing popular realization that American product quality and productivity are no longer without challenge for world leadership presents an opportunity for the American statistical community to make stronger contributions to sound industrial practice than it has in the past. Management consultants, such as Deming and Juran, are promoting philosophies that contain strong statistical components and are being heard by top U.S. executives. There are thus growing opportunities for industrial statisticians. Upon reviewing the content of typical graduate-level statistical quality control courses and books in the light of the present situation, we find them to be inadequate and in some cases to suffer from inappropriate emphases. In this article we discuss our perceptions of what is needed in the way of a new graduate-level course in statistics for quality and productivity (SQP). We further offer for discussion a syllabus for such a course (which is a modification of one used at Iowa State in the 1983 spring semester), some comments on how specific topics might be approached, and also a partially annotated list of references for material that we believe belongs in a modern SQP course.     

The Profit Squeeze and Its Effect on the Faxon Company from 1975–1994

Abstract

Open Access is increasingly considered the most logical and hopeful solution to ease the burden on library budgets, as well as the best way to unshackle research findings—its primary role. But is Open Access the panacea for all the ills that currently beset those of us dedicated to the dissemination and preservation of good quality academic research? In this article, Richard Gedye (Sales Director, Oxford Journals) explores the background to one of Oxford Journals' current Open Access initiatives and explains some elements of the model adopted. He also offers his personal opinions on the significant role librarians could play in the Open Access story.     

Non-parametric estimation of data dimensionality prior to data compression: the case of the human development index

In many applications in applied statistics, researchers reduce the complexity of a data set by combining a group of variables into a single measure using a factor analysis or an index number. We argue that such compression loses information if the data actually have high dimensionality. We advocate the use of a non-parametric estimator, commonly used in physics (the Takens estimator), to estimate the correlation dimension of the data prior to compression. The advantage of this approach over traditional linear data compression approaches is that the data do not have to be linearised. Applying our ideas to the United Nations Human Development Index, we find that the four variables that are used in its construction have dimension 3 and the index loses information.     

Not just another box to tick: Conflict‐sensitivity methods and the role of research in development programming

Reflecting on the experience of conducting a conflict‐sensitivity review during the 2010 political and social disturbances in Kyrgyzstan, the authors argue for the integration of conflict‐sensitive methods across programme areas, close monitoring of conflict potential and an institutional commitment to detailed conflict research drawing on broader socio‐economic research. Comparing their observations with the review findings of conflict sensitivity methods in Nepal, the authors offer recommendations for the application of ‘do no harm’ principles to development work in fragile environments. Ensuring the creation and systematic use of an adequate knowledge base is the critical first step to preventing the lessons that should be learnt from the Kyrgyz experience from being lost.     

Developing an Index to Measure Sub-municipal Level Urban Sprawl

The present study aims to develop an index composed of different spatial variables to measure the urban sprawl levels of a municipality located in Southern Spain. According to the findings, urban sprawl can be measured not only on the metropolitan level but also on a more detailed and precise level, such as sub-municipal. A group of experts chosen for their suitability in measuring urban sprawl select six spatial variables (population density, net residential density, coverage ratio, land use types, percentage of residential land use, and average year of construction). These variables are aggregated using Choquet integral, a technique that combines interactions between those variables providing greater coherence to the complexity that is inherent in the creation of composite sprawl indexes. This methodology has been demonstrated to be valid and appropriate in evaluating urban expansion at sub-municipal level, but can also be applied to other scales once it is clearly a phenomenon in which interaction between criteria exists. The resulting composite index allows the assignment of different levels of sprawl to the urban areas consistent with their morphology and landscape.     

Police militarization in the United States

In 2014, police responses to protests and riots in Ferguson, Missouri, prompted an unprecedented level of news coverage on the phenomenon of police militarization. Though the increased attention to police militarization and governmental programs thought to facilitate it (e.g., the 1033 Program) may give the impression that police militarization is a recent phenomena, social scientists have been documenting trends in police militarization for decades. This article provides an overview of the social science research literature on police militarization, starting with a discussion of a theory informed conceptualization of police militarization. We next discuss the major normative debates that have guided research on police militarization. We then review the empirical literature that focuses on the methodological approaches and findings of extant work on police militarization. Finally, we close with an overview of the state of the literature and suggestions for future research. Our major suggestion for future work is to consider the dimensions of police work that police militarization can occur in while continuing to engage with the normative debates of previous scholars so as to improve the overall quality of police work and public safety in the United States.
