Temperamental Factors in the Execution of Interrupted Editing Tasks

The question investigated in this study is how the temperament traits of strength of excitation (SE), strength of inhibition (SI), and mobility (MO) affect behaviour during the execution of computer tasks and tasks interrupting them. Several hypotheses, partly derived from the regulative theory of temperament, were tested in an experiment in which the natural environment and the types of task commonly performed by secretaries were simulated. The sample consisted of 39 female secretaries (21–64 years old). It was found that individuals high on SE and MO needed less time to resume tasks after an interruption than individuals low on these temperament traits. Interruptions similar to the main task resulted in longer resumption times for low-SE individuals. MO was negatively related to the time needed to perform the main task. A model describing the relationship between the frequency of switches between tasks and the speed of task performance in low-MO and high-MO individuals is presented.     

Contextual effects on word production: A lifespan study

The effect of sentence priming on picture naming was investigated across the lifespan, from age 3 to 87 years. Names that are normally acquired before 3 years of age were presented in auditory contexts that were semantically congruent, incongruent, or neutral in relation to each picture and its name. Sentential priming was present at all age levels. Facilitation (neutral vs. congruent) was significantly by 4 years of age and did not vary significantly with age. Interference (incongruent vs. neutral) was significant at all age levels, but changed nonmonotonically with age (largest in the youngest children, stable from young adulthood through age 70, with a small increase in the oldest participants). We conclude that picture naming is a useful tool for the investigation of sentential priming effects across the lifespan and that it can reveal potentially interesting developmental changes in the effects of sentential context on word retrieval.     

Change in self-stigma among persons with schizophrenia enrolled in rehabilitation: associations with self-esteem and positive and emotional discomfort symptoms

Self-stigma is a barrier to the recovery of persons with schizophrenia. Little is known about whether participation in rehabilitation is naturalistically linked to declines in self-stigma, and if so, what is correlated with changes in self-stigma. The current study examined in a quasi-experimental design the rate of change of self-stigma and whether changes were correlated with self-esteem, positive symptoms, and emotional distress for persons enrolled in rehabilitation. Symptoms were measured using the Positive and Negative Syndrome Scale (Kay, Fizsbein, & Opler, 1987), self-esteem was measured with the Multidimensional Self-Esteem Inventory (Lysaker, Ringer, & Davis, 2008), and self-stigma was assessed using the Internalized Stigma of Mental Illness Scale (Ritsher, Otilingam, & Grajales, 2003). Seventy persons with schizophrenia who worked at least one month in a vocational rehabilitation program were assessed on all measures at baseline and five months later. Results indicated a 25% decrease in self-stigma for 38% of the sample; these individuals tended to have less emotional distress both at baseline and follow-up, and had higher levels of self-esteem at follow-up. No differences in positive symptoms were found for groups whose stigma did or did not decrease. Results suggest that decreases in self-stigma may be correlated with increased self-esteem, while higher levels of emotional distress may be a barrier to stigma reduction.     

Group-based treatment for internalized stigma among persons with severe mental illness: findings from a randomized controlled trial

Elevated internalized stigma is common and is linked to subjective and objective outcomes for severe mental illness. The authors developed a manualized group-based intervention (Narrative Enhancement/Cognitive Therapy; NECT) to address internalized stigma in severe mental illness. The purpose of the present study was to evaluate the feasibility and effectiveness of NECT. In total, 144 individuals were screened at two sites to evaluate if they met criteria for "elevated" internalized stigma; 39 and were eligible were randomized to NECT or to treatment as usual (TAU) and were assessed at baseline, posttreatment, and 3-month follow-up. Fifteen of the 21 individuals assigned to NECT were classified as "exposed" to treatment. Intent-to-treat analyses found no significant difference between the NECT and TAU groups. A comparison of exposed versus unexposed participants noted trends for exposed participants to have improved more in two aspects of self-stigma as well as insight. We conclude that NECT is feasible and tolerable, but findings did not support the hypothesis that NECT was more effective than TAU, although small sample size and significant dropout may have restricted the ability to detect an effect.     

Work Motivation in “Post-Socialist” Industrial Organizations

Abstract

This article describes a study into the needs and behavioural reaction patterns in a sample of 715 workers in Bulgarian industrial firms during the “post-Socialist” period. The findings from this study cast doubt on some popular views of the typical motivation and reactions to work in the former “Socialist society”. Our data suggest that higher order needs are dominant in the motivational hierarchy and are significant in determining work outcomes, such as satisfaction, tendency to leave, and stress. We found no evidence for a motivational stereotype characterized by a low level of work involvement, lack of initiative, obedience, etc. hypothesized by other authors. In order to gain a better understanding of work motivation, it is useful to differentiate needs from the opportunities to satisfy those same needs, as well as work motivation from behavioural reaction patterns that actualize the opportunities and relate them to personal outcomes. A specific behavioural reaction pattern seems to exist among Bulgarian workers as an adaptation reaction to the specific environment of the “(post-) Socialist” industrial organization. This pattern, identified as “egocentrism in work”, combines a high involvement in work with partial alienation, i.e. detachment from the organization and income.     

Bringing actors together around large-scale water systems: Participatory modeling and other innovations

Conclusion The five areas of innovation found in the three case studies have brought actors together in new ways around water management strategies. We paid special attention to the role of participatory modeling, because it has been able to generate new policy options. For such complex and often deadlocked water management issues, new options are at a premium. The cases demonstrate that participatory modeling efforts are a key part of successfully addressing these major water management issues faced in the U.S. as well as elsewhere. Recent publications include Ecology, Engineering and Management: Reconciling Ecosystem Rehabilitation and Service Reliability (with Emery Roe; Oxford: Oxford University Press). Current research interest include the reliability of critical infrastructures (such as electricity, water, telecommunications and the internet) and the development of methods to recast the intractable policy issues. Since 1999, he has been a Visiting Scholar at the University of California, Berkeley and Mills College, Oakland. where he teaches and directs research in the application of economic theory and systems analysis methods to the solution of environmental and regional water resources problems. He has authored numerous articles and book chapters, served on various committees of the National Research Council of the National Academy of Sciences, and was a U.S. member of an advisory committee for the International Institute for Applied Systems Analysis (IIASA) in Laxenburg, Austria. Emery Roe has published widely on science, technology and environmental controversies, including the debates over large technical systems, sustainable development, and ecosystem management. His books include Narrative Policy Analysis (Duke University Press, 1994), Taking Complexity Seriously: Policy Analysis, Triangulation and Sustainable Development (Kluwer, 1998), Except-Africa: Remaking Development, Rethinking Power (Transaction, 1999), and Ecology, Engineering and Management: Reconciling Ecosystem Rehabilitation and Service Reliability (with Michel van Eeten; Oxford: Oxford University Press).     

Extended Mechanistic Explanations: Expanding the Current Mechanistic Conception to Include More Complex Biological Systems

Mechanistic accounts of explanation have recently found popularity within philosophy of science. Presently, we introduce the idea of an extended mechanistic explanation, which makes explicit room for the role of environment in explanation. After delineating Craver and Bechtel’s (2007) account, we argue this suggestion is not sufficiently robust when we take seriously the mechanistic environment and modeling practices involved in studying contemporary complex biological systems. Our goal is to extend the already profitable mechanistic picture by pointing out the importance of the mechanistic environment. It is our belief that extended mechanistic explanations, or mechanisms that take into consideration the temporal sequencing of the interplay between the mechanism and the environment, allow for mechanistic explanations regarding a broader group of scientific phenomena.     

The concept of the highest good in Kierkegaard and Kant

This article tries to make sense of the concept of the highest good (eternal bliss) in Søren Kierkegaard by comparing it to the analysis of the highest good found in Immanuel Kant. The comparison with Kant’s more systematic analysis helps us clarify the meaning and importance of the concept in Kierkegaard as well as to shed new light on the conceptual relation between Kant and Kierkegaard. The article argues that the concept of the highest good is of systematic importance in Kierkegaard, although previous research has tended to overlook this, no doubt due to Kierkegaard’s cryptic use of the concept. It is argued that Kierkegaard’s concept of the highest good is much closer to Kant’s than what previous research has indicated. In particular, Kant and Kierkegaard see the highest good not only as comprising of virtue and happiness (bliss), but also as being the Kingdom of God.     

Genetic studies of stuttering in a founder population

Genome-wide linkage and association analyses were conducted to identify genetic determinants of stuttering in a founder population in which 48 individuals affected with stuttering are connected in a single 232-person genealogy. A novel approach was devised to account for all necessary relationships to enable multipoint linkage analysis. Regions with nominal evidence for linkage were found on chromosomes 3 (P=0.013, 208.8 centiMorgans (cM)), 13 (P=0.012, 52.6 cM), and 15 (P=0.02, 100 cM). Regions with nominal evidence for association with stuttering that overlapped with a linkage signal are located on chromosomes 3 (P=0.0047, 195 cM), 9 (P=0.0067, 46.5 cM), and 13 (P=0.0055, 52.6 cM). We also conducted the first meta-analysis for stuttering using results from linkage studies in the Hutterites and The Illinois International Genetics of Stuttering Project and identified regions with nominal evidence for linkage on chromosomes 2 (P=0.013, 180-195 cM) and 5 (P=0.0051, 105-120 cM; P=0.015, 120-135 cM). None of the linkage signals detected in the Hutterite sample alone, or in the meta-analysis, meet genome-wide criteria for significance, although some of the stronger signals overlap linkage mapping signals previously reported for other speech and language disorders. EDUCATIONAL OBJECTIVES: After reading this article, the reader will be able to: (1) summarize information about the background of common disorders and methodology of genetic studies; (2) evaluate the role of genetics in stuttering; (3) discuss the value of using founder populations in genetic studies; (4) articulate the importance of combining several studies in a meta-analysis; (5) discuss the overlap of genetic signals identified in stuttering with other speech and language disorders.
