Självkänsla och familjestöd hos ungdomar med olika aggressionsroll : en representativ studie bland högstadieelever i Österbotten

Objektive: To examine differences in the degree of self-esteem and family support among adolescents involved in different aggression roles from Ostrobothnia in Finland and to examine the relation between aggression role, family support and self-esteem. Method: A sample of 3512 adolescents in school at grades 7 and 9 from Ostrobothnia was considered for this study. The sample consisted of 1741 boys and 1771 girls with the mean age of 14.3 years and SD of 1.10 years. Aggression was measured with the Mini Direct Indirect Aggression inventory (Mini-DIA) by Österman and Björkqvist (2008), self-esteem was measured with the Rosenberg Self-Esteem Scale (RSES) by Rosenberg (1965) and family support was measured with the family support part from the Multidimensional Scale of Perceived Social Support (PSSS) by Zimet, Dahlem, Zimet and Farley (1988). Chi-square test, multivariate analysis and regression analyses were carried out. Results: The boys reported higher self-esteem and received higher family support than girls. The adolescents who were involved in aggression as victims or perpetrators reported lower self-esteem and family support than adolescents who were not involved in aggression. The regression analyses showed that family support and aggression role had significant effects on the adolescents’ self-esteem in both boys and girls. There was also an interaction effect between family support and aggression role for girls, so that the difference in self-esteem between perpetrator-victims and control group for example was higher for girls with low family support than for girls with high family support.

Lower Cortisol Activity is Associated with First-Time Driving while Impaired

Driving while impaired (DWI) is a grave and persistent high-risk behavior. Previous work demonstrated that DWI recidivists had attenuated cortisol reactivity compared to non-DWI drivers. This suggests that cortisol is a neurobiological marker of high-risk driving. The present study tested the hypothesis that this initial finding would extend to first-time DWI (fDWI) offenders compared to non-DWI drivers. Male fDWI offenders (n = 139) and non-DWI drivers (n = 31) were exposed to a stress task, and their salivary cortisol activity (total output and reactivity) was measured. Participants also completed questionnaires on sensation seeking, impulsivity, substance use, and engagement in risky and criminal behaviors. As hypothesized, fDWI offenders, compared to non-DWI drivers, had lower cortisol reactivity; fDWI offenders also showed lower total output. In addition, cortisol activity was the most important predictor of group membership, after accounting for alcohol misuse patterns and consequences and other personality and problem behavior characteristics. The findings indicate that attenuated cortisol activity is an independent factor associated with DWI offending risk at an earlier stage in the DWI trajectory than previously detected.

Dissolution of Dynamic Electronic Institutions, a first approach: Relevant factors and causes

In the context of the digital business ecosystems, small organizations cooperate between them in order to achieve common goals or offer new services for expanding their markets. There are different approaches for these cooperation models such as virtual enterprises, virtual organizations or dynamic electronic institutions which in their lifecycle have in common a dissolution phase. However this phase has not been studied deeply in the current literature and it lacks formalization. In this paper a first approach for achieving and managing the dissolution phase is proposed, as well as a CBR process in order to support it in a multi-agent system

Los derechos de las mujeres: de la prohibición a la eliminación de la discriminación

En los últimos cinco decenios se han logrado muchas cosas, que hoy damos por sentado, con el fin de prohibir y eliminar las discriminaciones de género. Siglos de negación legalizada de la igualdad de derechos de las mujeres se olvidan fácilmente. A las mujeres se les concedió el derecho al voto en Nueva Zelanda en 1893, hace sólo 105 años, y se les otorgó el derecho a ser elegidas en Finlandia en 1908, hace tan sólo 90 años. A lo largo de los últimos cinco decenios, estas excepciones se han convertido en una regla, aunque en ciertos casos dicha regla aún es cuestionada.

Influences of space, soil, nematodes and plants on microbial community composition of chalk grassland soils

Microbial communities respond to a variety of environmental factors related to resources (e.g. plant and soil organic matter), habitat (e.g. soil characteristics) and predation (e.g. nematodes, protozoa and viruses). However, the relative contribution of these factors on microbial community composition is poorly understood. Here, we sampled soils from 30 chalk grassland fields located in three different chalk hill ridges of Southern England, using a spatially explicit sampling scheme. We assessed microbial communities via phospholipid fatty acid (PLFA) analyses and PCR-denaturing gradient gel electrophoresis (DGGE) and measured soil characteristics, as well as nematode and plant community composition. The relative influences of space, soil, vegetation and nematodes on soil microorganisms were contrasted using variation partitioning and path analysis. Results indicate that soil characteristics and plant community composition, representing habitat and resources, shape soil microbial community composition, whereas the influence of nematodes, a potential predation factor, appears to be relatively small. Spatial variation in microbial community structure was detected at broad (between fields) and fine (within fields) scales, suggesting that microbial communities exhibit biogeographic patterns at different scales. Although our analysis included several relevant explanatory data sets, a large part of the variation in microbial communities remained unexplained (up to 92% in some analyses). However, in several analyses, significant parts of the variation in microbial community structure could be explained. The results of this study contribute to our understanding of the relative importance of different environmental and spatial factors in driving the composition of soil-borne microbial communities.

Effect of 3,4-ethylenedioxy-extension of thiophene core on the DNA/RNA binding properties and biological activity of bisbenzimidazole amidines

Novel bisbenzimidazoles (4-6), characterized by 3,4-ethylenedioxy-extension of thiophene core, revealed pronounced affinity and strong thermal stabilization effect toward ds-DNA. They interact within ds-DNA grooves as dimmers or even oligomers and agglomerate along ds-RNA. Compounds 4-6 have shown moderate to strong antiproliferative effect toward panel of eight carcinoma cell lines. Compound 5 displayed the best inhibitory potential and in equitoxic concentration (IC(50) = 1 x 10 (6) M) induced accumulation of cells in G2/M phase after 48 h of incubation. Fluorescence microscopy showed that 5 entered into live HeLa cells within 30 min, but did not accumulate in nuclei even after 2.5 h. Compound 5 inhibited the growth of Trypanosome cruzi epimastigotes (IC(50) = 4.3 x 10 (6) M). (C) 2009 Elsevier Ltd. All rights reserved.

"Vi hava nu lykligt kommit hit i Norrland" : en gårdfarihandlarfamiljs handelsverksamhet och gårdshushåll i Månsta by, Älvdalens socken åren1865 -1886

Syftet med denna uppsats är att undersöka hur gårdfarihandlarfamiljen på Tommosgården i Älvdalens socken i norra Dalarna organiserade sin handelsverksamhet och sitt gårdshushåll under 1800-talets andra hälft. Ett särskilt fokus riktas mot de hemmavarande kvinnornas roll i verksamhet och hushåll. Undersökningen baseras på en familjebrevväxling, skriven mellan åren 1865-1886. Gårdfarihandeln var då en historiskt och traditionellt förankrad, populär utkomstmöjlighet för många älvdalsbor. Tommosfamiljen organiserade sin rörliga och fasta handelsverksamhet och sitt gårdsliv med jord- och skogsbruk i en familjedriven rörelse beroende av de hemmavarande kvinnorna. Männen ägnade sig åt handel långa perioder årligen då deras hustrur skötte gårdshushållet. Männen engagerade sig i arbetet på gården via brevväxlingen. Familjerörelsen organiserades med hjälp av en fungerande postgång. Den väl inarbetade genusarbetsdelningen i gårdshushållet var en konsekvens av familjens rörliga handelsverksamhet och verkar förändras mellan generationer

Omvårdnad vid Amyotrofisk lateral skleros : erfarenheter ur ett patient och anhörigperspektiv : En systematisk litteraturstudie

Amyotrofisk lateral skleros (ALS) är en fortskridande neurologiska sjukdom som ger den drabbade och de anhöriga mycket sorg och smärta. Syftet med föreliggande systematiska litteraturstudie var att utifrån aktuell vetenskaplig litteratur beskriva upplevelsen och behovet av omvårdnad som den sjuke i ALS och deras anhöriga behövde. Syftet var också att beskriva vilken typ av information och stöd som behövdes. De vetenskapliga artiklarna som ligger till grund för denna litteraturstudie har sökt på databaserna Elin@Dalarna och Blackwell Synergy. Artiklarna skulle vara publicerade mellan åren 2000-2007 och vara skrivna på engelska. Även manuella sökningar har gjorts. Resultatet visade att sjukvården hade ett stort ansvar att stötta, hjälpa och informera vid denna fortskridande neurologiska sjukdom. Det fanns behov av multiinriktad omvårdnad där många olika professioner ingick för att kunna ge patienterna den helhetsvård de behövde. Det framkom att anhöriga var de som hade den givna omvårdnadsrollen och att de hade ett behov av avlastning och information om sjukdomen, behandlingen och symtomen. Anhöriga upplevde sjukdomen som en stor börda och påverkade deras egna hälsa.

ICC-profilers funktionalitet vid byte av tryckfärgskvalitet

This degree theme work aims to evaluate the present ICC-profile and printing ink of Dalarnas Tidningar AB. The companyhas changed printing ink quality and wants to evaluate how the present ICC-profile work with the new printingink. Four different ICC-profiles were included in the comparison.One test printing was accomplished with two different separations. Two new ICC-profile was created, as a comparingmaterial. An densitometer was used to measure the technical parameters of the printing. IT8-charts and RGB-chartswas measured with spectrophotometer. La*b*-values, CMYK-values, graybalance curves, color deflections and colorgamuts was compared on screen and on the printed material.Materials from an earlier testprinting and evalution, made by Stora Enso Kvarnsveden AB 2003, was used to evaluatethe function of Dalarnas Tidningar AB´s ICC-profile with the present printing ink quality. The IT8-chart from todaystestprinting was oppened in a program for textediting to have access to La*b*- and CMYK values. The values from theearlier testprinting was supplied from Stora Enso Kvarnsveden AB.The result of this work shows that the ICC-profile from the company, compared with de other profiles, reproduce darkershadow regions which can make loss of details. An higher saturation is recieved in the red and yellow area while thegreen and blue area lose its intensity. The profile gave images which are some contrastless and with a flat reproduction.Today printing ink quality gives more saturation and intensity in the yellow and blue area compared with former printingink. The dark tone reproduces with decreased luminance, however.
