EARLY CORTICAL INFLUENCES IN OBJECT SEGREGATION AND THE PERCEPTION OF SURFACE LIGHTNESS

Abstract— The apparent brightness of a surface is profoundly influenced by the brightness of an adjacent surface., but these contrast effects are reduced when the surface are perceived as separate three-dimensional entities. Previous work has suggested that high-level perceptual and cognitive processes involved in scence segmentation may be responsible for modifying a surface's appearance. We demonstrate large reductions in contrast effects when the sues available for segmentations are restricted to those that isolate separate groups of early cortical neurons in the visual system. Our data contradict standard contract-signaling models of brightness perception and imply that mechanisms of figure-ground segmentation are already available at low levels of visual processing.     

Binding,narcissistic pathology and the psychoanalytic process

This article discusses the question of truth claims in psychoanalysis, revolving around the concepts “construction”, “reconstruction”, “historical truth” and “narrative truth”. In Part I of the article, these concepts are discussed in an historical context, in particular, Freud's view, the narrative tradition and some of Bion's ideas. In Part II, an attempt is made to synthesize these concepts. It is argued that the constructed character of the unconscious has to be integrated into the patient's reconstruction of his/her life story. The psychoanalytic project enables the patient to create a new narrative that claims to possess historical validity. It is important in this context not to understand the notion of “history” objectivisticallv as if it were a question of revealing certain objective historical facts. Instead, it is suggested that the connection between the present understanding of the past and the past as it was experienced in the past should be understood as a fusion of horizons. Finally, the necessary function of consciousnesslself-consciousness for the psychoanalytic project of acquiring knowledge about one's unconscious is pointed out.     

Technologies,Multitasking, and Driving: Attending to and Preparing for a Mobile Phone Conversation in a Car

This article investigates mobile phone calls initiated or received by drivers and passengers in cars and focuses on the participants' actions before the telephone conversation proper. Drawing on video‐recorded data of real driving situations, and building on conversation analysis and multimodal interaction analysis, this article discusses how participants temporally and sequentially coordinate situations that require multitasking, that is, use a phone while on the move. This article shows how participants draw on the current social‐interactional, material context to handle the call as relevant at that point and how they, through their vocal and bodily conduct, manage the prebeginning as a collaborative effort. The findings have relevance for research both on driving and on human–human and human–technology interaction.     

Association of pupil vandalism, bullying and truancy with teachers' absence due to illness: a multilevel analysis

The aim of this study was to examine whether vandalism, bullying, and truancy among pupils at school are associated with absence due to illness among teachers. Data on such problem behaviour of 17,033 pupils in 90 schools were linked to absence records of 2364 teachers. Pupil reported vandalism and bullying at the school-level were associated with teachers' short-term (1- to 3-day) absences. Cumulative exposure to various forms of pupils' problem behaviour was associated with even higher rates of short-term absences among teachers. No association was found between pupils' problem behaviour and teachers' long-term (>3-day) absences. In conclusion, there seems to be a link between pupils' problem behaviour and teachers' short-term absence due to illness. Further work should determine whether problem behaviour is a cause or a consequence of absences or whether the association is noncausal.     

Primal Scene Fantasies and Cathexis of Self as Reflected in the Psychoanalytic Situation

Close parallels are pointed out between the Jewish and the psychoanalytic way of structuring central patterns in their respective thinking. The central power in existence is The Undescribable One or That which is undescribable. The primary task of enlighted man is to remember and hope. An arch is raised from the past into the future and the creation appears as a so-far unfinished process—the final answers will be given first with the return of the profet Elias and Messiah. Thus, the preliminary nature of all our attempts at solutions is underscored.     

The theme of love in Henrik Pontoppidan's Nattevagt (Night watch) and other short novels

The subject of love may not seem an appropriate topic of scientific discourse, for we prefer turning to poetry to learn something meaningful about love. Nonetheless, we find three texts on the subject in Freud's work, all of which underline an internal division in love. He discussed the contrast between the affectionate and sensual aspects of love, while Lacanian writers have supplemented by pointing to the division between pleasure and desire. This article illustrates these concepts with cases taken from the Danish author Henrik Pontoppidan, one of the most prominent Danish writers from the turn of the 19^th century. He is well-known for his novels and for his short novels. One of these, Nattevagt, from 1894, has been read by critics as a marital conflict between the painter Jørgen Hallager and his fragile wife Ursula Branth, who succumbs to the brutality of her husband. The author supplements this simple version of the story with aspects made visible through the idea of an internal division in sexuality, which Freud elaborated into his theory of the death drive around 1920. By way of introduction, a few words are said about Pontoppidan, focusing on the theme of love in his short novels. Following is a brief summary of the plot of Nattevagt. Finally a more detailed reading of the dialogue between the two protagonists, Jorgen and Ursula, opens the way for a psychoanalytic interpretation of the tragic outcome of their love.     

Downsizing,changes in work,and self-rated health of employees: A 7-year 3-wave panel study

Abstract

The question of whether changes in work and interpersonal relationships mediate the adverse effects of downsizing on health of employees was explored. Longitudinal data from a 7-year study of 550 municipal workers in a variety of jobs was collected before, immediately after, and 4 years after downsizing. The degree of downsizing for each job category was assessed using organizational records of contracted days worked. Downsizing predicted adverse changes in work characteristics and a long-lasting decline in self-rated health. Decreased job control, high job insecurity and increased physical demands, in combination, appeared to be the linking mechanism between downsizing and general health. Interestingly, social conflict did not play a role in the mediation process.     

Human Costs of Organizational Downsizing: Comparing Health Trends Between Leavers and Stayers

We studied health-related selection and consequences of an organizational downsizing among 886 municipal employees. Measurements of health indicators were conducted before any rumor of the downsizing and immediately after the downsizing 3 years later. Results of predownsizing health showed that those who did not find employment after the staff reductions were older employees with high preexisting morbidity. Those getting a new job elsewhere were younger and had better health already before the downsizing than the stayers. After the downsizing, deterioration of health was most likely in the stayers working in groups of major staff reductions and among the nonemployed leavers. In the reemployed leavers, the risk of increased health problems was lower than in others including employees working in no or minor downsizing groups.
