Are People Emotionally Predisposed to Experience Lower Quality of Life? The Impact of Negative Affectivity on Quality of Life in Patients Recovering from Cardiac Surgery

Negative affectivity has been defined as a predisposition to experience intense states of negative emotions. As a trait concept it is a dimension that reflects stable and pervasive differences in negative mood and self-concept. There has been systematic evidence linking negative affectivity to anxiety, depression, psychosomatic complaints, pain symptoms, and adherence to life style changes. Several studies have demonstrated a link between negative affectivity and quality of life. However, as the majority of these studies have been cross-sectional, it has been difficult to establish causal relations between quality of life and negative affect. The present study is a longitudinal investigation of negative affectivity and quality of life in patients undergoing coronary artery bypass grafting (N = 157). Negative affectivity and quality of life were assessed with the Positive and Negative Affect Schedule (PANAS) and with the MacNew Quality of Life after Myocardial Infarction Questionnaire (MacNew QLMI) on admission day, one, and six months after the operation. Causal and reciprocal relationships were tested using a cross-lagged designs analysis via structural equation modeling. Results indicated that the causal model represented the best fit to the data. Results of the study are discussed in terms of the clinical importance of identifying patients at risk of experiencing severe restrictions in their quality of life.

Challenging the abuse decision: a comparison of American and British perspectives on complaints and appeals

The conclusion by child protection services that a child has been abused and the decision to make a formal record of that conclusion involves a process called'registration' in both the United Kingdom and the United States. This is an administrative process rather than a judicial one and is instituted by public officials not lawyers, but it can have as significant an effect on the families involved as the findings of a court Yet, despite this significance, families have found it very difficult to challenge the decision to register a case of abuse, particularly in the UK. This papers offers a critique of registration processes in the UK and in the USA and suggests ways in which these processes might be improved to protect individual rights.     

A Psychoanalytic Look at Recovered Memories, Therapists, Cult Leaders, and Undue Influence

There has been a dramatic increase in recovered memories of sexual abuse. A continuum of influence is presented, focusing on the high degrees of influence in cults, to understand how therapists can easily influence their patients to recover memories of sexual abuse. Historical evidence is given for a better appreciation of how this present atmosphere has developed. Finally, the role played by the psychoanalyst when dealing with recovered memories is examined. Case material is presented to highlight the differences between the traumatist's and the psychoanalyst's approach.     

Modifying a central composite design to model the process mean and variance when there are hard-to-change factors

Summary.  An important question within industrial statistics is how to find operating conditions that achieve some goal for the mean of a characteristic of interest while simultaneously minimizing the characteristic's process variance. Often, people refer to this kind of situation as the robust parameter design problem. The robust parameter design literature is rich with ways to create separate models for the mean and variance from this type of experiment. Many times time and/or cost constraints force certain factors of interest to be much more difficult to change than others. An appropriate approach to such an experiment restricts the randomization, which leads to a split-plot structure. The paper modifies the central composite design to allow the estimation of separate models for the characteristic's mean and variances under a split-plot structure. The paper goes on to discuss an appropriate analysis of the experimental results. It illustrates the methodology with an industrial experiment involving a chemical vapour deposition process for the manufacture of silicon wafers. The methodology was used to achieve a silicon layer thickness value of 485 Å while minimizing the process variation.     

Opportunities and challenges for industrial statisticians

The last 20 years have seen significant advances in the use of statistical methodology in industry, with applications in new product design and development, optimization and control of manufacturing processes, and in the service industries. The field of industrial statistics has emerged as an important branch of statistical science that focuses on this application environment. Yet as applications of statistics in industry have expanded, creating many new opportunities for the modern industrial statistician, many new challenges have arisen. Some of these challenges are technical, while others have managerial and organizational aspects. There are also important concerns pertaining to training and education. This presentation focuses on some of these issues, and identifies some potential solutions.     

The influence of nonverbal cues associated with looking behavior on young children's mentalistic attributions

The ability of children to use looking behavior as a cue to guide their mentalistic attributions was assessed. In Experiment 1 video displays were presented in which a protagonist faced one of two potential goals, half of the time standing equidistant from both targets and in the remaining trials standing closer to the target not being faced. Preschoolers consistently based their inferences of another's attention and goal on the direction in which the protagonist was facing. However, in Experiments 2 and 3 preschoolers experienced difficulty in correctly inferring an actor's desired goal when the protagonist's body was oriented in a direction opposite of where she was looking. Under these conditions, only young elementary school children consistently inferred that the protagonist's goal was the target being looked at (Experiment 2). The results from these three studies suggest that an important development occurring in childhood is the ability to consistently distinguish gaze from body orientation when inferring the goals of another. The implications of this development for children's understanding of the mind are discussed.
