Spitz nevus was first described by Sophie Spitz in 1948 as juvenile melanoma. The lesion is a benign melanocytic tumor, which consists of epiteloid- and spindelshaped cells. Histological is spitz nevus difficult to distinguish from malign melanomas and spitzoid melanomas. Loss of symmetry, loss of maturation in the deep component, nuclear polymorphism and hyper chromatic nucleus are features which can be found in melanomas. Some of these features are often seen in spitz nevus.

Today the individual ventilated cage system (IVC-system) is the most commonly used system when housing rodents. IVC systems are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare for two different strains of laboratory mice (NMRI nude mice and C57BL/6NCrl mice) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. 108 mouse pups from each strain (in total 216 mice) were selected after weaning at an age of three weeks and tested during 5 weeks.

I denna uppsats försöker jag förklara vad ungdomsbrottslighet innebär, vilka faktorer gör så att man som ungdom utför brottsliga handlingar och hamnar i kriminella gäng samt hur man på bästa sätt kan förebygga ungdomsbrottslighet. Jag har gjort en litteraturöversikt och sedan behandlat informationen med hjälp av två tidigare teorier, sociala bandteorin och inlärningsteorin. För att få mina frågeställningar besvarade har jag fokuserat på ungdomar och hur det kommer sig att de väljer en kriminell väg. I diskussion och resultat stycket presenterar jag vad jag kommit fram till i analysdelen och analyserar resultatet med dem valde teorierna. I uppsatsen tar jag även upp om det finns någon koppling mellan maskulinitet och brottslighet och iså fall vilken..

Most studies regarding wolf (Canis lupus) predation on moose (Alces alces) have focused on the total annual consumption of moose within a wolf territory but few have tried to describe the spatial impact of wolf predation on a local scale. In this study I have analyzed wolf movement data, wolf predation, moose hunting statistics and moose hunter observations to investigate how wolf predation affects the human harvest of moose in Scandinavia. Since wolves prey on mostly juvenile moose during summer, analysis of their summer movement patterns is crucial to understand its impact on the human harvest later during autumn. In this study both reproducing (n = 45) and non-reproducing wolves (n = 12) reduced their movement range during summer to 66% and 67% of their annual movement range, respectively. Reproducing wolves increased their movement range from early to late summer while non reproducing wolves did not.

Tall (Pinus sylvestris L.) är ett av Sveriges viktigaste trädslag. Med ökad efterfrågan på vedråvara samt ökade krav på naturavsättningar är det viktigt att öka produktionen i skogen. Röjning och tidig gödsling ger ökad volymproduktion men kan ge icke önskvärd påverkan på vedegenskaper som ökad mikrofibrillvinkel (MFV). MFV är vinkeln mellan mikrofibrillerna i cellväggens S2-lager och cellens längdaxel och påverkas av ståndort samt konkurrensen om ljus och näringsämnen. Höga MFV resulterar i sämre kvalitet på papper och sågade trävaror.

Att göra bedömningar av risk för våld hos frihetsberövade personer på fängelser och i olika former av tvångsvård är en viktig del av arbetet med att reducera antalet våldsincidenter, vilket är till nytta både för frihetsberövade personer och för personalens arbetsmiljö. Syftet med denna studie är att göra en kunskapsöversikt över vad forskningen säger om att bedöma risk för våld hos frihetsberövade personer, beskriva aktuell forskning om riskbedömningar, hur strukturerade instrument för riskbedömningar definierar våld, vilka teoretiska utgångspunkter till uppkomst av våld som används och i vilken utsträckning riskbedömningsinstrument tar hänsyn till interaktion mellan personal och frihetsberövade personer.Studien genomförs igenom en litteraturstudie med en innehållsanalys av forskning på området utifrån frågeställningarna i syftet. Sökorden är ?inmate?, ?inpatient?, ?violence?, ?risk?, ?assessment?, ?juvenile? och ?youth?.Reslutatet av studien visar att det finns ett flertal instrument som som forskningen visar har god validitet och även inter-bedömarreliabilitet för att bedöma risk för våld, nämligen Brøset Violence Checklist (BVC), Historical-Clinical-Risk management-20(HCR-20), Dynamic Appraisal of Situational Agression (DASA) och Structured Assessment of Violencerisk in Youth(SAVRY). Utöver detta finns även några bedömningsinstrument som använder enbart statiska variabler för att bedöma risk för våld hos frihetsberövade, även kallade aktuariska modeller.

Människor verkar tro att de är vanliga och som alla andra, men är det verkligen så eller tillskriver vi andra våra egna beteenden? Syftet med denna studie var att undersöka om det fanns ett samband i hur ungdomar projicerar sitt normbrytande beteende och hur de uppfattar sina kamrater. Människor tenderar att tro att andra reagerar på samma sätt som de själva gör, och därmed se sitt eget beteende som det typiska. För att undersöka projektionen användes en enkätstudie som ungdomar på en högstadieskola fick besvara. I enkäten skulle eleverna uppskatta sitt eget beteende och sina kompisars beteenden.

This study, which was conducted in Sweden, was based on four qualitative semi-structured interviews. The aim of this study was to create an understanding of how a municipality designs the sanction for youth offenders called ?youth service? based on the law that establishes the existence of such a sentence. We interviewed social workers that work at the department of youth service in the municipality of Gothenburg, who exclusively deal with youth offenders? sentenced to youth service as their job assignment.

The purpose of this study was to examine if there are common factors that lead to young people committing crimes according to professionals in social work, crime prevention and the police. The study also aims to examine if juveniles in Swedish suburbs commit more crimes, the consequences that follows and what actions socialworkers have for these juveniles. The study was conducted through qualitative interviews of five professionals in the area who were contacted from different units. In the analysis Goffmans (1971) theory of stigma was used and Goldberg's (2005) Conspiracy Theory. Some of the conclusions that could be drawn from the study was that there is not only one factor influencing young people to delinquency, but often combinations of different factors that lead to this.

The purpose of this study was to examine the mediators' views on their work; mediation by reason of the breach. The starting point was to find out the mediator's approach and attitude in relation to the perpetrator and victim, and the prevailing regulatory framework. After review of the literature, we came to the realization that knowledge of this area was very limited and thus presents an unexplored topic. It emerged from the results that the mediators emphasize the importance of maintaining impartiality and neutrality in the process of mediation and that it is important to create a good relationship with both parties. The methods used by the mediators is not so different much about, but the mediators apply Crime Prevention Council handbook.

Renal dysplasia is a developmental anomaly of the kidneys which is considered to be the primary lesion in juvenile progressive nephropathy, a condition leading to chronic renal failure in young dogs. It is defined as disorganised development of the renal parenchyma due to abnormal differentiation, and pathological lesions include persistent foetal structures, dysplastic tubules and cartilaginous and osseus metaplasia. The aetiology of renal dysplasia in dogs is still unknown, but possible causes are infection with canine herpesvirus, teratogenic substances or intrauterine ureteral obstruction. In some breeds renal dysplasia is a familial or inherited disease. Clinical signs of chronic renal failure, such as polyuria, polydipsia, vomiting, weight loss, anorexia, lethargy and anemia, usually appear before the age of 2 years.

ÖREBRO UNIVERSITYDepartment of Behavioural, Social and Legal SciencesC-essay in Social work, Advanced course2006To give up a criminal life styleA study of motivation and protectional factors of juveniles after a sentence of institutional care or community workEmma Henriksson & Karin TengnäsABSTRACTThe purpose of the study was to investigate the factors that juveniles sentenced to institutional care or community work perceive as important for their decision to give up a criminal life style. The study approach was based on a few specific questions: (1) What aspects of the treatment have contributed to a motivation to abandon the criminal life style? (2) What have motivated the juveniles to make a decision to leave the criminal life style? (3) Are there any specific internal or external protectional factors that have been decisive for the rehabilitation process and, if so, are they linked to intrinsic or extrinsic motivation? The study rests on the theoretical foundation created by earlier research on institutional care, motivation and protectional factors. Interviews were chosen as a method to secure qualitative data and the interview manual was designed on the basis of themes that reflect the questions of the study. Six young people?s perception of their treatment is documented in the study, as well as their opinion on the effectiveness of the treatment.

At the time of the study, there is no law to prevent an employer from doing criminal background checks. Employers for School and childcare have to do criminal background checks before hiring but the background checks have increased significantly in other industries as well. The aim of this thesis is to analyze and explain what interest employers may have in jobseekers history and how it can affect people?s privacy. To do this I have used right dogmatic approach combined with four interviews with different employers to get their perspective on the subject.

The aim of this study was to investigate how the authorities; Social Services, Police and the Office of public prosecutor co-operate with the voluntary organization; Unga KRIS in the matter of young offenders. The purpose was also to investigate the conditions, possibilities, vices and difficulties in the cooperation between the operators. This study was based on six semi-structured interviews with representative from all four operators. The empirical material has been analyzed through a new institutional theory which focuses on values and norms in an organization. The result of this study showed that there were a lot of conditions and possibilities too co-operate between the operators such as through personal contacts. Further the result illustrated a number of difficulties for example that the authorities? different laws don?t connect.
