XMM-Newton temperature maps for five intermediate redshift clusters of galaxies

We have analyzed XMM-Newton archive data for five clusters of galaxies (redshifts 0.223-0.313) covering a wide range of dynamical states, from relaxed objects to clusters undergoing several mergers. We present here temperature maps of the X-ray gas together with a preliminary interpretation of the formation history of these clusters. (c) 2007 COSPAR. Published by Elsevier Ltd.

GALAXY EVOLUTION IN A COMPLEX ENVIRONMENT: A MULTI-WAVELENGTH STUDY OF HCG 7

The environment where galaxies are found heavily influences their evolution. Close groupings, like the ones in the cores of galaxy clusters or compact groups, evolve in ways far more dramatic than their isolated counterparts. We have conducted a multi-wavelength study of Hickson Compact Group 7 (HCG 7), consisting of four giant galaxies: three spirals and one lenticular. We use Hubble Space Telescope (HST) imaging to identify and characterize the young and old star cluster populations. We find young massive clusters (YMCs) mostly in the three spirals, while the lenticular features a large, unimodal population of globular clusters (GCs) but no detectable clusters with ages less than a few Gyr. The spatial and approximate age distributions of the similar to 300 YMCs and similar to 150 GCs thus hint at a regular star formation history in the group over a Hubble time. While at first glance the HST data show the galaxies as undisturbed, our deep ground-based, wide-field imaging that extends the HST coverage reveals faint signatures of stellar material in the intragroup medium (IGM). We do not, however, detect the IGM in H I or Chandra X-ray observations, signatures that would be expected to arise from major mergers. Despite this fact, we find that the H I gas content of the individual galaxies and the group as a whole are a third of the expected abundance. The appearance of quiescence is challenged by spectroscopy that reveals an intense ionization continuum in one galaxy nucleus, and post-burst characteristics in another. Our spectroscopic survey of dwarf galaxy members yields a single dwarf elliptical galaxy in an apparent stellar tidal feature. Based on all this information, we suggest an evolutionary scenario for HCG 7, whereby the galaxies convert most of their available gas into stars without the influence of major mergers and ultimately result in a dry merger. As the conditions governing compact groups are reminiscent of galaxies at intermediate redshift, we propose that HCGs are appropriate for studying galaxy evolution at z similar to 1-2.

How does a riverine setting affect the lifestyle of shellmound builders in Brazil?

The contact of inland and coastal prehistoric groups in Brazil is believed to have been restricted to regions with no geographical barrier, as is the case in the Ribeira de Iguape valley. The inland osteological collection from the riverine shellmound Moraes (5800-4500 BP) represents a unique opportunity to test this assumption for this region. Despite cultural similarities between riverine and coastal shellmounds, important ecological and site distribution differences are expected to impact on lifestyle. The purpose of this study is thus to document and interpret health and lifestyle indicators in Moraes in comparison to coastal shellmound groups. Specifically we test if the rare evidence of fish and mollusc remains in the riverine shellmound led to (a) higher caries rates and (b) lower auditory exostosis frequency and (c) if the small size of the riverine shellmound translates into reduced demographic density and thus rarity of communicable infectious diseases. Of the three hypotheses, (a) was confirmed, (b) was rejected and (c) was partly rejected. Bioanthropological similarities between Moraes and coastal shellmounds include auditory exostoses with equally high frequencies; significantly more frequent osteoarthritis in upper than in lower limbs; cranial and dental morphological affinities and low frequencies of violent trauma. However, there are also important differences: Moraes subsisted on a much broader protein diet and consumed more cariogenic food, but showed a stature even shorter than coastal groups. Thus, despite the contact also suggested by treponematoses in both site types, there was enough time for the people at the riverine site to adapt to local conditions. (c) 2008 Elsevier GmbH.

Hot och våld i socialarbetares yrkesutövning : Threats and violence in the socialwelfare secretary occupation.

2004, the SSR, Akademikerförbundet, made a study on the threats and violence as a social secretary in the municipal social services are exposed in their occupation of the "social secretary of threats and violence at work" (T-110192), conducted by Temo ab. We have chosen to use the study on a smaller scale and then made contact with five municipalities in the middle of Sweden to investigate social secretaries experiences of threats and violence. Using the cross-sectional design and a convenience sample, we have gained access to data from 56 people. From a sociological perspective, we have chosen to use Norbert Elias theory of universal configuration and interdependence, and Michel Foucault’s theories concerning power search explanation for the existence of threats and violent situations in the contact between social workers and their clients.

Mobbing : Personlighet, kön och andra faktorers påverkan på människan

Mobbing är ett socialt problem. Därför skapades denna studie för att se om samband råder mellan mobbad, mobbare och personlighetsegenskaper. Dessutom gjordes en könsfördelning för att se om det råder några signifikanta skillnader i händelse, kön och personlighet. För att få svar på dessa syften ställdes frågorna: Hur ser mobbingen ut och vilka drabbas? Har kön och personlighetsegenskaper någon betydelse för om man blir mobbad eller utsätter andra för mobbing? Till hjälp användes en kvantitativ undersökningsmetod. En enkätstudie, där tre klasser i årskurs nio deltog. Det resultat som framkom var att tjejer i allt större utsträckning mobbar och mobbas och använder sig av mer grövre metoder än tidigare. Dessutom visar studien att det finns en signifikant skillnad i personlighet karakteristiska neurotisk och de som utsätts för mobbning.AbstractBullying is a social problem. Therefore this study was created to see if there was a connection between being bullied, bullies, and personality characteristics. In addition a balance to see if there was any significant difference in the event, gender and personality. To answer these objectives the questions were: What is bullying and who is affected? Do gender and personality characteristics have an impact on whether one is being bullied or subjecting others to bullying? A quantitative questionnaire survey was used in three classes for students in ninth grade. The results showed that girls were more widely both bullies and bullied. And apply the increasingly violent methods. In addition, the study shows that there is a significant difference in personality characteristic neuroticism and those that are subjected to bullying.

Förståelse, bedömningar och hjälpinsatser : Socialarbetares arbete med män som våldsoffer

This report outlines the background to, and presents the results from the Crime Victim Compensation and Support Authority funded project "Social Workers' understanding of men as victims of crime". The project aimed at describing and analyzing how social workers understand and work with male victims of violence. More precisely, the research has focused on how social workers describe men's vulnerability and how they understand men's needs for assistance, what assistance that is provided and the way the constellations of perpetrators and victims of different gender and contexts in which the violence occurs in affect the understanding of male victims of violence. The study has also been devoted to the question of whether the Support Centers for young crime victims in Sweden provide different types of and different amount of help to young men and women afflicted of violence. The project was conducted in three substudies. The results from substudy 1 show that more young men than women seek support from the Support centers studied. Men predominate in number of cases and in the different categories of crime. The results also show that young men on average receive less assistance over a shorter average duration than young women. This applies irrespective of the category of offense that the vulnerability applies to. Furthermore, the young men, compared to the women, proportionally receive fewer interventions characterized as support and a greater proportion of interventions in the form of information. The results also show that the young men are referred on for further action to a lesser extent than is the case for women. The results from substudy 2 show that social workers tend to focus on whether, and to what extent, young men who are victims of violence themselves have behaved provocatively before the violence incident and if they have put themselves in a social situation that could be interpreted as having contributed to an escalation of the violence they have been subjected to. The results from substudy 2 also show that social workers talk about the men as active in the violent situations they have been involved in and dwell on the extent to which the young men's own actions have contributed to the violence. The results also show that young men who are victims of violence are described as "reluctant" victims who are trying to cope with their situation on their own without the involvement of professional or other helper. The young men are also described as reluctant to talk about their feelings. The results of substudy 3 show that social workers believe that young men, when they become victims of violence, risks losing their sense of autonomy, initiative and decisiveness, that is, attributes that are often linked to the dominating cultural image of masculinity. Furthermore, the results show that social workers estimate that men's practicing of their masculinity, but also the response that men who are traumatized get from society, creates difficulties for them to get help. The results from substudy 3 also shows that attributes and actions that can be connected to the masculinity of young men's, as well as a lack of such attributes and actions are considered to be adequate explanations for the violence the men has suffered. When it comes to violence in public places it is the masculinity that explains the violence and its escalation. When it comes to domestic violence it is the lack of expected male attributes and actions that are used as explanations for the violence that have occurred. The discussion is devoted to the question of how the results should be understood based on the concepts of self-performance, interpretation, negotiation and categorizations, and the consequences the results obtained should have for gender sensitive social work given to abused men.

Biopolitik, civilsamfund og ’politisk eskatologi’ : Foucaults mistillid over for befolkningens indre kræfter

Biopolitics, Civil Society and Political Eschatology: Foucault’s distrust in the population’s inherent forces Michel Foucault’s scepticism toward discourses on the organic vitality of populations is not only explainable by his attention to the dark ‘underside of biopolitics – the risks of persecution of individuals, who threaten the population’s vitality from the inside. Moreover, it should be understood in light of Foucault’s acute sensitivity to the deep-seated, conflict-ridden nature of the population in terms of its inherent potential for cultural clashes, violent struggles, suspicions, hatred, or, in short, the perpetual conflicts of civil society. Foucault’s work led him to a position of ambiguous support for the state and to a more evident distrust in the forces of the population. He used the term “political eschatologies” about antipolitical visions that pronounce the end of politics in a final accord where social contradictions dissolve and the community will prevail over the state. Foucault played on the religious significations of the term, especially in regard to the religious, fanatic rejection of the duality between state and civil society, a rejection that rests on the belief in a completion of historical and political time and the final salvation of all in “the city of God”. The article demonstrates Foucault’s highly ambiguous view of civil society, it examines his discussion Ferguson’s work on civil society, and it considers Foucault’s use of the term “political eschatologies” to indicate the dangers of extreme, anti-state, political movements. It challenges the image of Foucault as an unequivocal proponent of grass roots and identity politics.  

The core characteristics and nursing care activities in psychiatric intensive care units in Sweden

Internationally, research on psychiatric intensive care units (PICUs) commonly reportsresults from demographic studies such as criteria for admission, need for involuntary treatment, andthe occurrence of violent behaviour. A few international studies describe the caring aspect of thePICUs based specifically on caregivers’ experiences. The concept of PICU in Sweden is not clearlydefined. The aim of this study is to describe the core characteristics of a PICU in Sweden and todescribe the care activities provided for patients admitted to the PICUs. Critical incident techniquewas used as the research method. Eighteen caregivers at a PICU participated in the study bycompleting a semistructured questionnaire. In-depth interviews with three nurses and two assistantnurses also constitute the data. An analysis of the content identified four categories that characterizethe core of PICU: the dramatic admission, protests and refusal of treatment, escalating behaviours, andtemporarily coercive measure. Care activities for PICUs were also analysed and identified as controlling– establishing boundaries, protecting – warding off, supporting – giving intensive assistance, andstructuring the environment. Finally, the discussion put focus on determining the intensive aspect ofpsychiatric care which has not been done in a Swedish perspective before. PICUs were interpreted asa level of care as it is composed by limited structures and closeness in care.

Definitioner av våld i överlevandes berättelser efter kriget i Bosnien

Definitions of violence in stories of survivors from the Bosnian war Previous research on violence during the war in Bosnia and Herzegovina presents a one-sided picture of the phenomenon ”war violence.” Researchers have emphasized the importance of narratives but they have not focused on stories about war violence, nor have they analyzed the stories of war violence being a product of interpersonal interaction. This article tries to fill this knowledge gap by analyzing the narratives told by survivors of the war in northwestern Bosnia in the 1990s. The aim is to analyze how the survivors describe violence during the war, and also to analyze those discursive patterns that contribute in constructing the category ”war violence.” The construction of the category ”war violence” is made visible in the empirical material when the interviewees talk about (1) a new social order in the society, (2) human suffering, (3) sexual violence, and (4) human slaughter. All interviewees define war violence as morally reprehensible. In narratives on the phenomena ”war violence” a picture emerges which shows a disruption of the social order existing in the pre-war society. The violence practiced during the war is portrayed as organized and ritualized and this creates a picture that the violence practice became a norm in the society, rather than the exception. Narratives retelling violent situations, perpetrators of violence and subjected to violence do not only exist as a mental construction. The stories live their lives after the war, and thus have real consequences for individuals and society.

Emotional responses to filmed violence and the eye blink startle response

The study assessed gender differences in emotional responses to violent film. Both subjective emotional response and eye blink startle magnitude were assessed while 20 men and 20 women viewed a series of five violent film segments and five nature scenes. Participants exhibited higher levels of curiosity, anxiety, disgust, and anger, and lower levels of positive emotion and boredom in response to the violent film segments in comparison with the nature material. Startle response was magnified during the violent film segments, indicating an aversive response. Evidence that men and women responded to the violence differently was demonstrated by men' experiencing greater positive feelings, entertainment, and curiosity in relation to the violent film, whereas women reported more disgust, boredom, anger, and experienced greater startle in relation to the violent scenes portrayed in the film. Future directions for investigating filmed violence are outlined.

Is domestic violence learned? The contribution of five forms of child maltreatment to men's violence and adjustment

On the basis of a learning-theory approach to the intergenerational transmission of violence, researchers have focused almost exclusively on violent men's childhood experiences of physical abuse and witnessing family violence. Little consideration has been given to the coexistence of other forms of child maltreatment or the role of family dysfunction in contributing to violence. This study shows the relationships between the level of child maltreatment (physical abuse, psychological maltreatment, sexual abuse, neglect, and witnessing family violence), childhood family characteristics, current alcohol abuse, trauma symptomatology, and the level of physical and psychological spouse abuse perpetrated by 36 men with a history of perpetrating domestic violence who had attended counseling. As hypothesized, a high degree of overlap between risk factors was found. Child maltreatment, low family cohesion and adaptability, and alcohol abuse was significantly associated with frequency of physical spouse abuse and trauma symptomatology scores, but not psychological spouse abuse. Rather than physical abuse or witnessing family violence, childhood neglect uniquely predicted the level of physical spouse abuse. Witnessing family violence (but not physical abuse) was found to have a unique association with psychological spouse abuse and trauma symptomatology. These results present a challenge to the understanding of domestic violence obtained from learning theory.

The Australian union merger wave revisited

What factors explain the Australian trade union merger wave between 1991 and 1994? Existing explanations largely attribute it to the pro –amalgamation policy of the Australian Council of Trade Unions (ACTU)and other union leaders,and to declining union membership and decentralised bargaining. This paper reviews discussion of the causes of mergers and publicly available evidence upon them. It concludes that current explanations of the merger wave are an over–simplification. The effects of ACTU leadership, official union policy,and members' views are complex and not uniform and require more disaggregated analysis. Also,there has been a tendency to overstate the importance of membership decline and decentralised bargaining and to over – look other environmental factors such as changing occupational structure. The paper cautions against the assumption that variables influencing ACTU policy also shape affiate actions.

The Dawson report and merger regulation

Discusses the Review of the Competition Law Provisions of the Trade Practices Act recommended by the Dawson Committee in Australia. Prohibition of mergers that lessens market competition by Trade Practices Act 1974; Requirement for a request of informal clearance; Establishment of an optional formal clearance procedure; Submission of merger authorization requests to the Australian Competition Tribunal.

Structural change in Australian trade unionism, 1969-1996: a structural events approach

Traditional studies of long-term change in trade union structure have, in constructing explanations of change, predominantly focused on aggregate trends in union merger activity. This paper argues that our understanding of structural change in the Australian trade union movement would be better served by a structural events approach that examines the incidence of union formations, dissolutions and breakaways, in addition to that of union mergers. In doing so, it outlines how these structural events can be identified and measured, and presents the preliminary findings from the method's application.
