Public space as 'context' in assistive information and communication technologies for people with cognitive impairment

This paper examines emergent issues of 'context' raised by the application of information and communication technologies for people with cognitive impairment. The issue of the development and application of cognitive prostheses for this group provides an opportunity to examine assumptions and issues emerging from this area pertaining to understandings of the term 'context' in these applications. In this sense the paper takes these assumptions and issues as a point of departure for the development of a 'problematic' that can contribute to the study of the experience of cognitive impairment. The paper specifically addresses recent concerns about the lack of knowledge of these experiences in public spaces such as shopping centres, given that this is a critical site for the civic participation of this group. We argue that this participation should be understood in terms of the 'meeting of two histories': the history of contemporary requirements governing participation in public space and the habitus of people with cognitive impairment with regard to this participation. The paper proposes that the salience of cognitive impairment in these spaces turns on what it means for individuals to inhabit them as complex 'Container Technologies' (Sofia) and underlines the importance of understanding their efforts to attain a sense of normality (Goffman) in these contexts. We propose that this approach can inform research contributing to the development of a 'pattern language', informing applications that make cognition a system property in networks that operate between humans, machines and their contexts.

Contingent factors: Modeling generic public relations practice in South Korea

This study identified which contingent variables public relations practitioners perceive as influential to their practice in South Korea. They responded that a number of contingent variables influence public relations activities and emphasized the influence of individual and organizational level variables on their practice. Practitioners at the management level perceived organizational level variables as influential while the staff level indicated PR department variables as dominant to their practice. Public relations practitioners whose main function is government relations tended to acknowledge a greater influence of organizational level variables. Most notably, public relations practitioners cited the constraints of negative information release and conflict situations.     

Antisocial and Prosocial Teasing Among Children: Perceptions and Individual Differences

Two studies examined fifth‐ and sixth‐grade students’ perceptions of antisocial and prosocial teasing among peers and potential correlates of individual differences in their tendencies to engage in both forms of teasing. The children were rated as showing a greater tendency to be prosocial teasers than antisocial teasers by both teachers and peers. In addition, the children indicated that they generally experienced and observed prosocial teasing more frequently than antisocial teasing at home and in school. Although boys were perceived to tease in a hostile, antisocial manner to a greater extent than were girls, the evidence for a gender difference in affiliative, prosocial teasing among these children was relatively weak. Additionally, systematic relations were found among ratings of the children's tendencies to engage in antisocial and prosocial teasing with peers, teachers’ ratings of their general level of antisocial and prosocial behavior with peers, ratings of the frequency with which they experienced antisocial and prosocial teasing at home and at school, and their attitudes toward antisocial and prosocial teasing.     

Ambivalence in the Relationship of Adult Children to Aging Parents and In‐Laws

The concept of ambivalence emphasizes the complexity of family relations and the potential for individuals to evaluate relationships as both positive and negative. Using multilevel models, we investigate ambivalence in adult children's relationships with their aging parents and in‐laws (N= 1,599). We focus on factors predicting adult children's ambivalence toward parents and in‐laws within a gendered kinship structure that shapes these relations. We conclude that ambivalence is a useful concept for representing the complexity of parent‐child relationships and is produced within the context of social relations structured by gender and kinship. Results show greater ambivalence among dyads of women, toward in‐laws, among those in poor health, for daughters providing assistance, and for adult children with poor parental relations in early life.     

Improved Estimation of the Pareto Location Parameter Under Squared Error Loss

Suppose two independent observations are drawn from Pareto distributions with known shape parameters and an order restriction on the unknown location parameters. An isotonic regression estimator of the smaller location parameter dominates a preferred marginal estimator under squared error loss, but fails to dominate under stochastic domination. The results expressed herein advance the theory of order restricted inference.     

Admissible estimation in an one parameter nonregular family of absolutely continuous distributions

Consider the problem of estimating under squared error loss an arbitrarily positive, strictly increasing or decreasing parametric function based on a sample of size n in an one parameter nonregular family of absolutly continuous distributions with both endpoints of the support depending on a single parameter. We first provide sufficient conditions for the admissibility of generalized Bayes estimators with respect to some specific priors and then treat several examples which illustrate the admissibility of best invariant estimators in some location or scale parameter problems.     

Discussion: The Recent Reappearance of the Homotheticity Restriction on Preferences

A model linking final demand (sales) with intermediate manufactures is estimated and simulated over the course of a business cycle. The results show that prices fluctuate more for early-stage manufactures than for later-stage products at the manufacturing and retail level. This is found to be largely due to inventory and unfilled orders fluctuations, particularly those of inventories of primary manufactured products held by finished goods manufacturers. Since these inventory fluctuations lead the cycle in final demand, prices of primary manufactures lead business activity. Another result is that inventories of materials and supplies, including those of retailers for resale, exhibit more instability than producers' inventories of finished goods.     

Estimating DEA confidence intervals with statistical panel data analysis

This paper describes a statistical method for estimating data envelopment analysis (DEA) score confidence intervals for individual organizations or other entities. This method applies statistical panel data analysis, which provides proven and powerful methodologies for diagnostic testing and for estimation of confidence intervals. DEA scores are tested for violations of the standard statistical assumptions including contemporaneous correlation, serial correlation, heteroskedasticity and the absence of a normal distribution. Generalized least squares statistical models are used to adjust for violations that are present and to estimate valid confidence intervals within which the true efficiency of each individual decision-making unit occurs. This method is illustrated with two sets of panel data, one from large US urban transit systems and the other from a group of US hospital pharmacies.
