Clustering of gamma-ray bursts through kernel principal component analysis

We consider the problem related to clustering of gamma-ray bursts (from “BATSE” catalogue) through kernel principal component analysis in which our proposed kernel outperforms results of other competent kernels in terms of clustering accuracy and we obtain three physically interpretable groups of gamma-ray bursts. The effectivity of the suggested kernel in combination with kernel principal component analysis in revealing natural clusters in noisy and nonlinear data while reducing the dimension of the data is also explored in two simulated data sets.     

“Feeling for Beauty”

ABSTRACT

May Morris (1862–1938), renowned craftswoman and daughter of William Morris, had an unconventional Victorian childhood in a home where all the members of the family were engaged in various forms of aesthetic labor, either as amateurs or professionals, and shared an aesthetic philosophy that blended the artisanal and the experimental from which would develop the Arts and Crafts movement. This article will examine the fragmentary recollections of her childhood recorded by May Morris in the introductions she wrote for the twenty-four-volume edition of The Collected Works of William Morris as a rich resource for Victorian sensory history because of the emphasis she places on the development of the child's sensorium, especially in relation to touch as the vital sense that linked family intimacy with creative activity. Employing the term “tactile aesthetics,” I show how, in the Morris household, the pleasurable sensual apprehension of the objects or materials worked by the hands of the craftsperson was inseparable from the complex feelings of connection with others. In such an environment, a feeling for beauty comprised a vital component of habitus, the embodied knowledges and aptitudes that, according to Pierre Bourdieu, are acquired from earliest childhood through the practices of everyday life within a specific social setting.     

Body-Related Emotions in Posttraumatic Stress Disorder Following Childhood Sexual Abuse

Traumatic experiences are associated with emotions such as anxiety, shame, guilt, disgust, and anger. For patients who have experienced child sexual abuse, these emotions might be triggered by perceptions of their own body. The aim of this study was to investigate the extent of the association of the body to traumatic experiences and to discern the emotions linked to trauma-associated body areas. Ninety-seven female participants were assigned to four groups: post-traumatic stress disorder following child sexual abuse with co-occurring borderline personality disorder, post-traumatic stress disorder following child sexual abuse without co-occurring borderline personality disorder, borderline personality disorder without post-traumatic stress disorder, and healthy controls. Participants rated 26 body areas regarding their association with trauma and 7 emotions. Emotions were assessed by questionnaires. Results suggest that specific areas of the body are associated with trauma and linked to highly aversive emotions. In post-traumatic stress disorder patients, the areas associated with highly negative emotions were the pubic region and inner thighs. Thus, the patient’s body may act as a trigger for traumatic memories.     

‘When you have no law you are nothing’: Cane toads,social consequences and management issues

In this article we demonstrate that Yanyuwa people have detailed biological knowledge of their northern Australian environment, which is culturally defined and embedded within their relationships to country, resources and each other. Through a case study of the impact of Bufo marinus (cane toads) on Yanyuwa culture and everyday life, we argue that Aboriginal management strategies and Aboriginal peoples’ intimate knowledge of species and environment need to be understood as both legitimate and fundamental when engaging in management initiatives in Australia. We demonstrate that for Yanyuwa people emotional engagement with their environment is underpinned by a morality of social and environmental relations and that ‘memory’ is pivotal to this engagement. We conclude by briefly delineating how the adoption of a ‘moral ecology’ perspective goes some way to addressing issues pertinent to discursive encounters at cultural management frontiers.     

Migrant encounters with neo-colonial masculinity: producing European sovereignty through emotions

The EU/European political community’s reaction to irregular migrants is ambivalent. On the one hand, migrants are produced as people to be pitied, rescued, and saved. On the other hand, they are feared, despised, and left to die. The article explores this ambivalence from a gender perspective and asks how sovereign masculinities are produced through emotional performances in the politics of migration control and management. It will be argued that emotions such as fear, disgust, and compassion are performed in the biopolitical security governance of irregular migration by producing a “socially abject” life as its object. This is a life that is to be killed, despised, and saved. Encounters between the irregular migrant and a European border security actor constitute a neo-colonial masculinity. During the moment of the encounter with the other’s life, sovereignty is produced through emotional performances of border security actors. The discussion concludes with illustrations of how racialized bodies and lives are produced as objects of fear, disgust, and compassion through European neo-colonial masculinity. The article speaks to the debates in the literature on masculinities in global politics, emotions and politics, and critical border studies.     

Towards ‘New Emotional Movements’? A Comparative Exploration into a Specific Movement Type

In this article we broaden the scope of earlier research that established a theoretical specificity for the Belgian ‘White March’ and ‘White Movement’, by comparing them to three similar movements and mobilizations that were also triggered by random violence. The comparisons suggest that we are dealing with a new type of social movement and mobilization, preliminarily referred to as ‘new emotional movements’. The three other cases under study are the ‘Snowdrop Campaign’ in the UK, the ‘Million Mom March’ in the US and the ‘Movement against Senseless Violence’ in the Netherlands. Four important features seem to characterize all cases: the central role of emotions and victimization in the mobilization and development of the movement; broad elite support; organizational weakness; and extensive media support. We distinguish two sub-types of new emotional movements: (1) an instrumental variant with clear-cut aims and demands; and (2) an identity variant with displays of solidarity and compassion as the main constitutive elements. In both cases the initiators lack prior organizational experience and the absence of mobilizing organizations is compensated for by mass media support. In the instrumental sub-type neither the victims nor their relatives take the initiative but lend support and give approval to amateur entrepreneurs. The main mobilizing emotion appears to be fear about the possibility of personal suffering, and this emotion is reflected in the formulation of clear-cut demands for the future prevention of similar events. This instrumentality results in elite support being considerably broad, yet partisan. In contrast, the victims themselves take the initiative in the identity variant, causing the movement to remain more or less without specific demands but ensuring a broad support that is not bounded by party lines.     

The golden star: an emotional repertoire of scientific discovery and legacy

This paper examines vocabularies of emotion in the discovery narratives of a group of genetic scientists. The discovery of the gene for myotonic dystrophy in 1992 was part of a unique and highly competitive phase of molecular genetic research into single gene hereditary conditions. Members of a small group of scientists who made a significant contribution to the discovery of the gene were interviewed sixteen years later about the impact of that discovery. They structured their memories into narrative accounts characterized by vivid recall, colourful language and use of an emotional repertoire to reconstruct the dynamics, relationships and personal meaning of the discovery. The focus of this emotional language was on what it meant to be a molecular scientist, the dynamics of the incremental work that led to eventual success, the networks surrounding the team and the legacy of discovery in relation to science and to the individual scientists. The emotional repertoire revealed subtle differences between accounts, where there was universal recognition of the importance of the discovery for a scientific career but ambivalence regarding its personal meaning for some key actors.

Quality of life,intelligence and mood

We investigated the relationship between quality of life (QOL), general ability and current mood in a sample of young men (N=269, mean age 24.9 years). Intelligence (verbal, spatial and mathematical) and technical ability were uncorrelated with QOL. Current mood such as pleasure, anger, sadness, boredom correlated firmly with QOL. The paper concludes that intelligence seems to be a variable of minor interest for QOL-studies.     

Writing from practice

This study investigates the effects of integration change on the integration success of German acquisitions in Poland. It is argued that the degree of integration change has a positive impact on two success measures, namely, economic growth and efficient co-operation, in the acquisition target. It is further argued that process transparency, participation and positive reinforcement are moderators in this relationship between degree of integration change and integration success. Hypotheses are tested on 521 Polish employees from twenty-nine German acquisitions made in Poland between 1991 and 1999. The results show that there was a positive relationship between degree of integration change and integration success as expected and that only process transparency emerged as a significant moderator of this relationship. Consequences for post-acquisition management after German acquisitions in Poland and limitations of the study are discussed.
