When it happens : Credible effects of a nuclear disaster in Sweden

Werlin, Ola January 2009 (has links)
Talking about nuclear disaster most people would probably come to think about the accident in Chernobyl 1986. Experts at the WHO has described the accident as follows “The magnitude and scope of the disaster, the size of the affected population, and the long-term consequences make it, by far the worst industrial disaster on record.”[1] It is impossible to tell where or even if a disaster like this will ever happen again, but still if it does happen, most people would probably agree that you like to be as prepared as possible. With this in mind this study has tried to look at credible effects of a nuclear disaster in Sweden. To get a grip of the consequences caused by a nuclear disaster this study has been performed as a comparative study, where research results from the Chernobyl accident presented by IAEA and WHO has been compared with actual circumstances in Sweden. When starting out the author of this thesis had a picture of a nuclear accident as the ultimate disaster that will bring death and destroy enormous areas of land and water for many years to come. However as this study proceeded many of the effects of a nuclear accident might not be as horrifying as they might seem. Saying this, it does not in any way mean that a nuclear accident would not have an enormous impact on those affected by it. As this study will show much of the impact of a nuclear disaster might be avoided by the right type of action at the right time. This calls for authorities being well aware and prepared for the risks connected with such a disaster. As this study will show this might not always be the case of Swedish authorities.

Mitochondrial DNA phylogeography of Norway spruce (Picea abies) in Northern Europe

Sahid, Md.Hasan January 2012 (has links)
Norway spruce (Picea abies L. Karst.) is an important conifer tree species widely distributed in Europe. Genetically, the population of this large range is divided in two differentiated groups: a southern and a northern European group. In the northern European group, the fossils records tell us that after the last glaciation this species recolonized from one main refugium located around the Moscow region, in Russia.             In this study, the genetic diversity and structure of 101 populations of Norway spruce collected all over the northern European range were examined using an indel polymorphism in mitochondrial DNA (mtDNA). The polymorphism was used to investigate the migration routes of this species after the last glaciation.                        The distribution of the detected two haplotypes (A and B) was geographically well structured as haplotype A was restricted to Scandinavia, while haplotype B was found all over the examined range. The value of averaged intrapopulation gene diversity (HS=0.09) was lower than total populations gene diversity (HT=0.28) and a relatively high value of genetic differentiation among populations was detected (GST=0.68). The genetic structure detected in this study suggested that a second refugium for spruce might have been present in Scandinavia. This study would shed light on our understanding of the postglacial migration history of Norway spruce.

Vilka personliga egenskaper är utmärkande för spelberoende indivder samt vilka konsekvenser medför ett spelberoende för individen

Karlsson, Madeleine, Karlsson, Magnus, Palmqvist, Martin January 2007 (has links)
For many individuals gambling gives an opportunity for relaxation and social relations. The positive effects of gambling are for most individual’s considerable more than the negative effects. Even if gambling gives positive effects there is individuals that cannot control there gambling and therefore develop an addiction which disturb there life situation and health. The aim of this study was to describe which personal characteristics distinguish people with a pathological gambling and which psychological, physical and social consequences this pathological gambling causes for the individual. The method of the study was a literary study and was based on twenty scientific articles. These articles were found in different scientific databases. The result of the study indicated that pathological gamblers have a higher grade of impulsivity and therefore they are seeking for quick satisfaction. The characteristic of pathological gamblers causes psychological, physiological and social consequences. Pathological gamblers have a increased risk of economical problems, work loses, anxiety, fear and depression. The consequences of pathological gambling does not only affect the individual with the addiction but also people in the person’s environment; therefore it is important that the society receive increased knowledge about pathological gambling. Further research about which individual’s that have an increased risk of become pathological gamblers, research about the increased accessibility to gamble and the mass medium effect on the individual is a desire.

ConsequÃncias emocionais, cognitivas e comportamentais da vitimizaÃÃo por roubo / Emotional, cognitive and behavioral outcomes of robbery victimization

Leonardo Carneiro Holanda 09 June 2017 (has links)
FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico / O termo âassaltoâ à usado no cotidiano referindo-se à aÃÃo de um ou mais indivÃduos, comumente armados, que abordam outras pessoas para roubar os seus bens. Embora esse termo nÃo seja empregado no CÃdigo Penal Brasileiro, hà sanÃÃo prevista para o crime de roubo, cuja descriÃÃo à similar à definiÃÃo de assalto. O roubo apresenta uma considerÃvel gravidade por pressupor o uso da forÃa, podendo levar as vÃtimas a Ãbito. AlÃm disso, danos decorrentes de um roubo restringem a capacidade dos indivÃduos de exercer adequadamente diversos papÃis, como o parental, conjugal e ocupacional, acarretando em prejuÃzos significativos nas relaÃÃes interpessoais em diversos ambientes, tais como familiar, escolar e laboral. Em face desses elementos, o presente estudo tem como principal objetivo avaliar o impacto cognitivo, emocional e comportamental da vitimizaÃÃo por roubo. Especificamente, espera-se estimar se e quais variÃveis situacionais especÃficas contribuem para maiores sequelas nas vÃtimas e avaliar em que medida os fatores protetivos e agravantes, apontados pela literatura, apresentam relevÃncia em contexto local. Para alcanÃar os objetivos propostos, foram realizados dois estudos empÃricos. Nesses estudos, contou-se com a participaÃÃo de 348 pessoas de diversos estados do Brasil. O Estudo I comparou vÃtimas e nÃo-vÃtimas no que se refere aos fatores apontados como possÃveis complicaÃÃes decorrentes do crime, enquanto o Estudo II avaliou o impacto individual de variÃveis contextuais especÃficas nas diversas sequelas decorrentes do crime e o efeito especÃfico dos fatores protetivos. Como resultado, pode-se observar, no Estudo I, que as vÃtimas e nÃo-vÃtimas se diferenciaram quanto a ansiedade, medo do crime, percepÃÃes de vulnerabilidade e autoeficÃcia, alÃm da tomada de algumas medidas de proteÃÃo. No Estudo II, observou-se que somente as estratÃgias de Controle e Retraimento, ConversÃo e Aditividade apresentaram relaÃÃo com os impactos analisados. O Suporte Social nÃo apresentou qualquer relaÃÃo com as consequÃncias do roubo. Tais resultados foram discutidos com base na literatura. Considera-se que os objetivos da presente dissertaÃÃo tenham sido alcanÃados uma vez que foi possÃvel analisar os impactos decorrentes da vitimizaÃÃo por roubo e seus correlatos que apresentam mais destaque na literatura. Contudo, pode-se apontar algumas limitaÃÃes na pesquisa, como a dimensÃo reduzida da amostra e qualidade de algumas medidas utilizadas. Para pesquisas futuras, sugere-se a utilizaÃÃo de amostras maiores, alÃm da adaptaÃÃo prÃvia das escalas para contexto local e a realizaÃÃo de estudos longitudinais. / The term mugging is used in the everyday referring to the action of one or more individuals, commonly armed, who approach other people to steal their property. Although this term is not used in the Brazilian Penal Code, there is an expected penalty for the crime of robbery, whose description is similar to the definition of mugging and differs from the crime of theft. Robbery is more serious because it presupposes the use of force, which can lead to death. In addition, damages resulting from a robbery restrict the ability of individuals to properly exercise various roles, such as parental, marital and occupational, resulting in significant impairment in interpersonal relationships in various settings, such as family, school, and work. In view of these elements, the present study has as main objective to evaluate the cognitive, emotional and behavioral outcomes of robbery victimization. Specifically, it is expected to estimate if and which specific situational variables contribute to greater sequelae in the victims and to evaluate to what extent the attenuating and aggravating factors pointed out in the literature are relevant in the local context. In order to achieve the proposed objectives, two empirical studies were carried out: Study I compared victims and non-victims with regard to factors identified as possible complications of crime, while Study II assessed the individual impact of specific contextual variables in the various sequelae and the specific effect of mitigating factors. As a result, it can be observed in Study 1 that victims and non-victims differed in terms of anxiety, fear of crime, perceptions of vulnerability and self-efficacy, and the taking of some protective measures. In Study 2, it was observed that only Control and Retraining, Conversion, Addiction strategies presented a relation with the analyzed impacts. Social Support was not related to the consequences of the robbery. These results were discussed based on the literature. It is considered that the objectives of this dissertation have been reached since it was possible to analyze the impacts of robbery victimization and its correlates that are more prominent in the literature. However, it is possible to point out some limitations in the research, such as the reduced size of the sample and the quality of some measures used. For future research, we suggest the use of larger samples, besides the previous adaptation of the scales to local context and the realization of longitudinal studies.

Adult Children of the Incarcerated: An Exploratory Study of Risks and Outcomes Among College Students

Gadson, Shari B 06 May 2012 (has links)
To date, research concerning children affected by parental incarceration has focused primarily on children that are eighteen years of age and younger. The effects of parental incarceration on adults that are eighteen years of age and older has remained unexamined. The purpose of this exploratory study is to explore the outcomes of young adult college students that have been affected by parental incarceration. A sample of 345 undergraduate college students was surveyed at a sizeable University in the southeastern region of the United States to create a demographic and behavioral profile of college students affected by parental incarceration. It was hypothesized that college students affected by parental incarceration will have lower institutional grade point averages (GPA), higher accounts of criminal involvement, higher likelihoods of substance abuse, and lower levels of self-control than college students that have not been affected by parental incarceration. Results indicated that, the outcomes of college students affected by parental incarceration were comparable to college students not affected by parental incarceration.

The evolutionary consequences of sperm senescence in Drosophila melanogaster

Han, Xu 13 March 2014 (has links)
Sperm senescence, a decline in sperm quality caused by male ageing and by sperm ageing before or after copulation, may have fitness costs manifested as infertility or lowered genetic quality of offspring. This thesis tested the distinct evolutionary roles of sperm senescence using a laboratory-adapted population of Drosophila melanogaster. We developed a practical approach to avoid confounding male age with sperm age by standardizing pre-copulatory sperm age and mating history in young and old male age groups. Applying this approach, we documented sperm senescence in D. melanogaster and discussed its potential evolutionary importance. First, ageing males declined in fitness as evidenced by the reduction in fertilization potential of their ejaculates but not by decreased offspring fitness (the ability that a fly can survive to adulthood, successfully mate and produce viable offspring). This suggests a decline in the quality or quantity of seminal fluid or spermatozoa, with no decline in the genetic quality of sperm that actually fertilized ova. Second, post-copulatory sperm senescence has significant negative impacts on offspring fitness, indicating degraded genetic integrity of the spermatozoa stored in females. In both cases, male ageing and sperm ageing had similar fitness impact on male and female offspring, different from what has been suggested by previous work. In addition, We demonstrated that female fecundity, fertility, and length of the fertile period after a single mating were positively associated with the concentration of yeast in their food, and were negatively associated with the duration of yeast restriction in their diet, which suggested that sperm storage is affected by the nutritional status of the females. By revealing the significance of sperm senescence on male and female fertilization success and the fitness of the next generation, this thesis sheds light on a number of evolutionary and applied issues, and provokes new questions for future research on sperm senescence. / Thesis (Ph.D, Biology) -- Queen's University, 2014-03-07 10:38:12.879
