National Differences in the Diffusion and Design of Technological Innovation: The Role of Inter-Organizational Networks

This paper reports results from a study of the design and diffusion of computer-aided production management (CAPM) technologies across four European countries (UK, France, The Netherlands and Sweden). The study combined surveys of members of professional operations management associations in each of these four countries and interviews with operations managers and technology suppliers (software suppliers and consultants). The findings revealed significant differences across countries in the design and diffusion of CAPM. For example, in the UK and France highly objectified 'best practice' technologies, supported by standardized software, had diffused more widely than in Sweden and The Netherlands, where solutions tended to be developed in-house and customized to the local context. This paper explains these findings in terms of differences in the structure and operation of these four professional association networks. These differences in inter-organizational networking encouraged different types of knowledge-sharing related to the design of CAPM in the four countries.     

Infants' Transitions out of a Fussing/Crying State Are Modifiable and Are Related to Weight Status

Currently, about 10% of infants have a weight for length greater than the 95th percentile for their age and sex, which puts them at risk for obesity as they grow. In a pilot obesity prevention study, primiparous mothers and their newborn infants were randomly assigned to a control group or a Soothe/Sleep intervention. Previously, it has been demonstrated that this intervention contributed to lower weight‐for‐length percentiles at 1 year; the aim of the present study was to examine infant behavior diary data collected during the intervention. Markov modeling was used to characterize infants' patterns of behavioral transitions at ages 3 and 16 weeks. Results showed that heavier mothers were more likely to follow their infants' fussing/crying episodes with a feeding. The intervention increased infants' likelihood of transitioning from a fussing/crying state to an awake/calm state. A shorter latency to feed in response to fussing/crying was associated with a higher subsequent weight status. This study provides preliminary evidence that infants' transitions out of fussing/crying are characterized by inter‐individual differences, are modifiable, and are linked to weight outcomes, suggesting that they may be promising targets for early behavioral obesity interventions, and highlighting the methodology used in this study as an appropriate and innovative tool to assess the impact of such interventions.     

Perception of Parental Reciprocity Scale (POPRS): Development and Validation with Adolescents and Young Adults

The present paper describes the development of a new scale, the Perception of Parental Reciprocity Scale (POPRS), and research findings obtained with this instrument. Based on Youniss' (1980) theory, this scale assesses the extent of perceived mutual reciprocity in adolescents'/young adults' relations with their parents. An initial pool of 51 items was administered to 141 unmarried undergraduates along with measures of self-esteem, locus of control, and consultant choice to indicate construct validity. Item analyses and reliability procedures produced a 43-item scale. A second study of 1602 students between the ages of 13 and 25 examined further issues: cross-replication, cross-validation, reliability with young adolescents, reliability over time, criterion and construct validity, and age-related differences in scores. In addition to POPRS and the scales used in Study 1, measures included three global statements, attachment to parents, attitude to private personal authority, and scores on an open-ended interview. Results from both studies demonstrated high reliability, and construct and criterion validity. Furthermore, a significant age effect supports Youniss' theory of a developmental transformation in parent-child relations beginning in late adolescence and continuing in early adulthood.     

Revenge: Interplay of Creative and Destructive Forces

This paper presents a theory about degrees of revenge and proposes creative, libidinal, and contained ways in which to express this otherwise destructive desire. A review of the literature on revenge first underlines its inherent ubiquity, self-preservative, and adaptive propensities. The exploration of the topic draws from cultural, social/judicial, and clinical texts to elucidate the interplay of creative and destructive elements in revenge. I have used the Structural Model developed by Freud to illuminate and sharpen the argument about revenge because I feel that it is a particularly efficient lens through which to view the issue and because I regularly draw from Freudian and post-Freudian theories, amongst others, in my assessment and interventions with clients.     

Integrating professional socialization and training for sociology graduate students

It is a curious contradiction that sociology, a discipline that includes in its subject matter socialization, norms, occupations, formal organization, the institution of education and the concept of the career does not necessarily prepare its products in a systematic and coherent manner to become trained professionals. Newly minted Ph.D.s must often learn by trial and error because we have left them adrift concerning how to conduct themselves as professional sociologists. Moreover, while these new Ph.D.s are usually trained well as scholarly researchers, many are not prepared for the non-research careers they will take as sociologists. When this happens, we sociologists, supposedly enlightened about such matters, have failed our students. This article is divided into two parts. The first is a critique of traditional graduate education in sociology. The second part plays off these criticisms by offering a coherent plan, consonant with the current and future possibilities for sociologists.     

Ten Suggestions for Effectively Teaching Short Courses to Heterogeneous Groups

Consider teaching a three-day short course in modern regression methodology to a small group consisting of engineers, social scientists, managers (who often have a business background), and medical researchers. Teaching such a course offers a different set of problems and challenges than encountered when teaching a course in the university setting. The instructor must be highly organized, well prepared, and flexible for the successful presentation of an intense short course. Ten suggestions are given that will increase the likelihood that the course will meet the educational objectives of such a diverse audience.     

Fractional principal components regression: a general approach to biased estimators

Several biased estimators have been proposed as alternatives to the least squares estimator when multicollinearity is present in the multiple linear regression model. The ridge estimator and the principal components estimator are two techniques that have been proposed for such problems. In this paper the class of fractional principal component estimators is developed for the multiple linear regression model. This class contains many of the biased estimators commonly used to combat multicollinearity. In the fractional principal components framework, two new estimation techniques are introduced. The theoretical performances of the new estimators are evaluated and their small sample properties are compared via simulation with the ridge, generalized ridge and principal components estimators
