A semi-parametric approach to robust parameter design

Parameter design or robust parameter design (RPD) is an engineering methodology intended as a cost-effective approach for improving the quality of products and processes. The goal of parameter design is to choose the levels of the control variables that optimize a defined quality characteristic. An essential component of RPD involves the assumption of well estimated models for the process mean and variance. Traditionally, the modeling of the mean and variance has been done parametrically. It is often the case, particularly when modeling the variance, that nonparametric techniques are more appropriate due to the nature of the curvature in the underlying function. Most response surface experiments involve sparse data. In sparse data situations with unusual curvature in the underlying function, nonparametric techniques often result in estimates with problematic variation whereas their parametric counterparts may result in estimates with problematic bias. We propose the use of semi-parametric modeling within the robust design setting, combining parametric and nonparametric functions to improve the quality of both mean and variance model estimation. The proposed method will be illustrated with an example and simulations.     

Armed robbery and the meanings of money

In this study, we investigate the meanings active armed robbers give to money before, during, and after their crimes and how these meanings shape their offending. We do so by examining interviews undertaken from 1994 to 1995 with robbers in St. Louis, Missouri, USA. Prior to their robberies, the interviewees' desperation leads them to define money as essential to survival. Immediately following robberies and in looking back on them, they come to view this essential money in other ways as well—as too time-consuming to get, as “easy,” or as guilt-free. These meanings facilitate the contradictory way robbers see money as “fast” after offences. We discuss how these shifting meanings of money shape and are shaped by robbers' structural positions, cultural outlooks, and social relations. In doing so, we also help to explain how the shifting meanings of money play into criminogenic cycles of predatory offending.     

Attributions and Avowals of Motive in the Study of Deviance: Resource or Topic?

In explaining human actions, scholars and laypeople alike employ explanatory devices such as 'motives'. This paper critically reevaluates the relationship between 'professional' and 'lay' invocations of motive, proposing a general reorientation of theory and research. This reorientation emphasizes the mundane 'practical grammar' of motives, and argues that motive deployment is inextricably tied to deviance, and therefore irremediably moral. It is argued, therefore, that motives should serve as a topic for scholarship, not a resource for scholarly use. Several landmark theories of motives, deviance, and explanations are critically reviewed from the proposed vantage. Finally, a brief survey of similarly-minded work is offered, focussing on ethnomethodological arguments and findings, as illustrations of the heuristic power and promise of the outlined approach.     

Differential customer racial attitudes toward scandal and patriotism: The Mitchell Report,the Olympics,race, and baseball memorabilia

This paper investigates differential customer racial reaction to negative and positive publicity related to professional athletes. In terms of negative publicity, it analyzes the effect of mention in the Mitchell Report on the price of baseball cards. In regards to positive publicity, it considers the impact of having been identified as a member of the United States Olympic or national team. After controlling for player productivity with performance statistics, the effects of being mentioned in the Mitchell Report are isolated within regression analysis to draw conclusions concerning customer racial attitudes toward the steroids scandal. Similar analysis is conducted to see the impact of being seen as a baseball representative of the United States. Regression results are consistent with the conclusion that negative publicity devalues the cards of nonWhite players but not of White players. Positive publicity, however, increases the value of a player's card regardless of ethnicity.     

Finding Bhaskar in all the wrong places? Causation,process, and structure in Bhaskar and Deleuze

This article examines the reception of Roy Bhaskar amongst some contemporary Deleuzians. It proceeds by rejecting the all too often predilection of opposing realism to ‘postmodernism’ or ‘post‐structuralism’ arguing instead for the need to bring one into dialogue with the other. To this end, the paper explores the resonances and points of departure between the work of Gilles Deleuze and Roy Bhaskar. In particular, it examines the language of causation, object‐oriented versus process‐oriented ontologies, as well as the charge by Deleuzians that Bhaskar is an essentialist. Through this engagement it attempts to develop and rethink explanation and causation in terms of a more chaotic ontology of machines, centered around the concept of structure, process, and production in an open, heterogeneous, and dynamic world. The end result is a more chaotic concept of realism.     

Are We Playing the Same Game?: Publishing Task Environments and Research Productivity Among Management Specialists

Archival data on over 15,000 contributors to 33management journals are used to examine productivitydifferences among scholars in different areas ofmanagement. The results suggest that a fragmentedpublication network offers specialists from different areasdissimilar publication opportunities and experiences,and may contribute to varying levels of publicationproductivity among authors. The implications of our results for future research and facultyevaluation processes are explored.     

Practical Treatments Considering the Role of Sociocultural Factors on Problem Gambling

Reviews of problem gambling (PG) literature increasingly recognize the ways in which different ethnic groups are affected by gambling behaviors, yet discourse, which considers sociocultural factors within PG, remains limited. Literature on this topic is influenced by large inconsistencies amongst research studies, overlapping terminology, and variability in the validity of research studies, making conclusions difficult to draw. Despite these discrepancies, this paper explores how sociocultural factors influence PG among diverse cultural groups and provides specific practical implications for treating PG disorders in culturally diverse populations. Notable factors that exacerbate PG behavior cross-culturally include substance abuse, low socioeconomic status, lack of social activities, and geographic location. Culturally sensitive treatment options such as Motivational Interviewing and Cognitive Behavioral Therapy have been identified as effective treatments for PG with culturally diverse populations. This paper extends current thought by providing practical treatment recommendations that consider the subtle nuances of diverse populations. It explains how treatment providers and behavioral addiction professionals can increase their understanding and skills when conceptualizing PG clients from a diverse background.     

What is a person‐centred approach? Familiarity and understanding of individualised funding amongst carers in New South Wales

Person‐centred approaches place individuals with a disability at the centre of decision making, with their carers and family invited to be partners in the process. Rather than being required to fit within existing service programs, person‐centred approaches enable individuals to choose the support options that best meet their needs. In order to facilitate this, person‐centred approaches will be accompanied by the introduction of individualised funding. This means the individual will be provided with funding to purchase services of their choosing. Given these significant changes occurring in the disability sector, Carers NSW surveyed informal carers of people with a disability to identify what they knew about person‐centred approaches and how they felt about their introduction. Survey results indicate that there is a need to increase the capacity and willingness of carers significantly in order to engage with person‐centred approaches and individualised funding. Carers require targeted and comprehensive information about these concepts in order to understand fully the changes occurring within the disability sector. These findings also indicate specific areas that need to be addressed in order to increase carers' awareness of these concepts and also to address existing negativity and confusion.     

Disabled or differently-enabled? Dyslexic identities in online forum postings

This study presents a novel exploration into how people with dyslexia construct personal identities within anonymous, unsolicited, postings to an online discussion forum. An interpretational phenomenological analysis suggested three key identities: learning-disabled, differently-enabled and societally-disabled. These are discussed in terms of the extent to which they draw differentially on a discourse of disability as opposed to one of individual difference. The identities are to an extent malleable and overlapping according to context. Postings suggested overall that while some contributors constructed themselves as differently-enabled and celebrated dyslexia-related abilities, others sensed themselves having a disabled identity imposed upon them. Dyslexia is perceived as negatively construed within a society which promotes literacy and cognitive acuity as essential aspects of educational and social competence and where learning differences are poorly tolerated. In addition, this study highlights the potential of online forum contributions in the study of social influences in under-researched groups.
