    This article examines why the Obama administration in 2011 decided to commit U.S. armed forces into Libya and in 2013 decided to seek congressional authorization for the use of military force in Syria. This paired comparison illustrates how the combined effects of bureaucratic politics and the president’s leadership style contributed to the decision-making process of two different decision-making outcomes. The study finds mixed empirical support for the explanatory power of the bureaucratic politics model in both cases. The study also finds that the extent of presidential preeminence in the decision-making enables the understanding of yes in Libya and no in Syria

    Lax, Salmo salar, har en anadrom livscykel. Den spenderar delar av sitt liv ute i saltvatten i havet innan den simmar tillbaka till sitt söta hemvatten för lek. För en del laxar blockeras de naturliga vandringsvĂ€garna till lekplatsen av vattenkraftverk. Konstgjorda laxtrappor byggs ibland för att underlĂ€tta vandringen. Denna rapport bestĂ„r av en undersökning av den vuxna laxens migration i VindelĂ€lvens laxtrappa vid kraftverket Norrfors Ă„ren 2017-2019. Innan smolten, den unga laxen, vandrar ut till havet har den dĂ€r mĂ€rkts med radiotaggar som sedan kan registreras pĂ„ antenner i laxtrappan dĂ„ de pĂ„börjar sin klĂ€ttring tillbaka. Tack vare detta gĂ„r det att se om det att bedöma hur lĂ„ng tid olika grupper lax spenderade i diffusorn i början av trappan, hur lĂ„ng tid klĂ€ttringen uppför trappan tog, och hur stor andel av laxen som fullbordade klĂ€ttringen. De senaste Ă„ren har en hög grad sjuklighet observerats bland laxar i bland annat VindelĂ€lven, sĂ€rskilt tidigt pĂ„ sĂ€songen. DĂ€rför Ă€r tidig (lax som kommit juni-juli) och sen (som kom augusti-september) lax en av grupperna som jĂ€mförts. Övriga grupper som jĂ€mförts Ă€r vild lax mot odlad lax, dĂ€r odlad lax har sitt ursprung nedanför trappan, samt grilse mot MSW-lax, dĂ€r grilse Ă€r lax som spenderat en vinter i havet och lax som spenderat flera vintrar i havet kallas MSW-lax (Multi sea winter-lax). Resultaten visade skillnader bĂ„de pĂ„ tiden i diffusorn och tiden för klĂ€ttringen mellan vild och odlad lax. Det fanns ingen skillnad mellan den tidiga och den sena sĂ€songens lax pĂ„ tiden i diffusorn eller tiden för klĂ€ttring. DĂ€remot fanns en skillnad i hur stor andel lax som simmade in i trappan under sĂ€songerna. Skillnaden i andel mellan sĂ€songerna skulle kunna bero pĂ„ den sjukdom som har observerats i VindelĂ€lven. NĂ€r grilse och MSW-lax jĂ€mfördes fanns det en skillnad pĂ„ tiden som spenderades i diffusorn, samt tiden för klĂ€ttringen. Detta kan ocksĂ„ ha pĂ„verkats av sjukdomen.Atlantic salmon, Salmo salar, has an anadromous life cycle. They spend parts of their life in saline water in the ocean, and later migrate back to their fresh home waters to spawn. Some salmon find their migration pathways blocked by hydraulic power stations. Here, human-made salmon stairs are sometimes built to make the ascent easier. This report aims to investigate and analyze the adult salmon’s upstream migration up the VindelĂ€lven salmon ladder the year’s 2017-2019. Before the smolt, the young salmon, migrated to the ocean, they were tagged so that they could be registered by antennas in the ladder when they begin their journey back. Because of this it is possible to determine the amount of time different groups of salmon spent in the entrance pool, the amount of time their ascent up the ladder took, and what portion of the salmon managed to successfully finish this ascent. In recent years a high amount of disease has been observed in the river VindelĂ€lven among others, especially early in the season. Because of this, early season salmon (arriving at the ladder in june-july) and late season salmon (arriving in august-september) is one of the groups being compared. The other groups are wild salmon compared with hatchery-reared salmon, and grilse compared with MSW-salmon. Grilse is salmon that has spent only one winter out at sea, while salmon spending more sea winters at sea before spawning are called Multi sea winter-salmon (MSW-salmon). The results showed a difference in both the time spent in the entrance pool and the time spent in the ascent of the ladder between wild and hatchery-reared salmon. There were no differences in the time the early and late season salmon spent in either the entrance pool nor the ladder. There was however a difference in the portion of salmon that begun their ascent up the ladder between the seasons. This difference between the early and the late season could be a result of the disease that has been seen in the river VindelĂ€lven. When grilse and MSW-salmon was compared a difference was found in the time spent in the entrance pool, as well as the time ascending the ladder. These results could also be affected by the disease

    Motivation in drum education – A study in drum students intrinsic and extrinsic motivation What motivates drum students to practise their instrument? The purpose of this study is to get an insight of what factors motivates to play and prioritize the instrument. Motivation is of both intrinsic and extrinsic nature. The intrinsic motivation drives us to act without getting any external reward while the extrinsic motivation drives us to act to get a reward that doesn’t have to do with the context. A qualitative survey was implemented where students from school of music, school of art and students from arts program answered questions regarding their interests in drumming. The survey has been processed and interpreted based on hermeneutic theory. The results show that most students who begin to practise an instrument do it because of outer influences. Those who decide to continue their playing have increased the intrinsic motivation and have a goal with their playing. Positive feedback from family and friends is significant and playing in ensemble is considered fun and stimulating.Vad motiverar trumelever att spela sitt instrument? Syftet med denna studie Ă€r att fĂ„ en inblick i vilka faktorer som motiverar att spela och prioritera sitt instrument. Motivation Ă€r av bĂ„de inre och yttre natur. Den inre motivationen driver oss att handla utan att fĂ„ yttre belöning, medan den yttre motivationen driver oss att handla för att fĂ„ en belöning som inte hör ihop med handlingen i sig. En kvalitativ enkĂ€tundersökning har genomförts, dĂ€r elever frĂ„n musikskola, kulturskola och estetiska programmet har svarat pĂ„ kvalitativa frĂ„gor angĂ„ende deras intresse för trummor. EnkĂ€ten har bearbetats och tolkats med grund i hermeneutiken. Resultatet visar att de flesta som börjar spela ett instrument gör det av en yttre pĂ„verkan. De som vĂ€ljer att spela under en lĂ€ngre tid har hittat den inre motivationen och har ett mĂ„l med sitt spelande. Positiva reaktioner frĂ„n omgivningen Ă€r betydande och att spela tillsammans med andra anses vara bĂ„de roligt och viktigt för utvecklingen

    The agriculture sector is one of the major sources to produce greenhouse gases of today. One big contributor is methane (CH4) generated during rumen digestion of the feed carbohydrates. One approach to lower CH4 output from the agriculture sector, is to change the diet for the cows. Diets with extruded linseed (EL) have in earlier studies showed to have a lowering effect on CH4 output from cows. Previous studies have shown correlations between CH4 output and fatty acid (FA) profile of milkfat. EL has also shown in previous studies to influence the FA profile in milkfat. The objects of this study were to evaluate if CH4 output can be reduced if diets are supplemented with extruded linseed, if CH4 increases the concentration of unsaturated FA in milk fat, and the effect of EL on milk yield. In this study a total of 177 cows from five herds were individually scanned for CH4 output, milk fatty acid profile and milk yield. Cows were studied while fed a control diet, during the treatment diet with EL and when going back to the control diet again. EL diets had no effect on milk yield but increased the unsaturated FA in the milk. EL also decreased the CH4 output from the cows with 22% from the first control period to the treatment diet, however there was no increase of CH4 output between treatment period and second control period. Conclusion of this master thesis is that Extruded linseed did not affect the milk yield. EL had an effect on milk fat composition. Due to the unreliable measuring method of methane this study could not point out an obvious decrease of CH4 due to EL.Lantbruket Àr en betydande kÀlla till dagens globala utslÀpp av vÀxthusgaser. VÀxthusgasen metan produceras i kons vÄm nÀr fodret smÀlts. Ett sÀtt att minska dessa utslÀpp frÄn lantbrukssektorn Àr att förÀndra foderstaten för boskapen. Att inkludera extruderat linfrö (EL) i foderstaten har i tidigare försök visat sig minska metanutslÀppet. Tidigare försök har Àven visat att det finns en korrelation mellan metanutslÀpp och mjölkfettets fettsyreprofil samt att EL pÄverkar mjölkfettets fettsyreprofil. I denna studie har totalt 177 kor frÄn 5 gÄrdar medverkat för att undersöka ELs effekt pÄ mjölkavkastning, fettsyrasamansÀttningen i mjölken och metanutslÀpp frÄn kor. Kornas metanutslÀpp mÀttes totalt tre gÄnger under testperioden. Första gÄngen under en kontrollfoderstat andra gÄngen under behandlingsfoderstat med EL och slutligen under ytterligare en kontrollfoderstat. Denna studie visar att EL inte hade nÄgon effekt pÄ mjölkavkastningen. EL ökade de omÀttade fettsyrorna och minskade de mÀttade fettsyrorna i mjölken. EL minskade metan utslÀppen per kg ECM med 22 % mellan första kontrollperioden och den följande perioden med behandlingsfoderstaten. Dock erhölls ingen förÀndring i metanutslÀpp dÄ korna Äter fick kontrollfoderstaten. Slutsatsen av denna studie Àr att EL hade en effekt pÄ mjölkfettsyraprofilen. PÄ grund av mÀtmetoden kunde inte studien visa pÄ ett tydligt minskat metanutslÀpp beroende pÄ EL

    Mot bakgrund av att vissa arbetsgivare infört obligatorisk trĂ€ning under arbetstid för sina anstĂ€llda Ă€r syftet med denna uppsats att utreda vilken möjlighet arbetsgivare har att beordra sina anstĂ€llda att trĂ€na under arbetstid. Uppsatsen utreder hur trĂ€ning kan införas som del av arbetsskyldigheten, hur arbetsgivaren bör beakta sitt arbetsmiljöansvar och var grĂ€nsen gĂ„r för arbetstagares personliga integritet. Slutsatserna Ă€r som följer. TrĂ€ning kan, under vissa förutsĂ€ttningar, införas som del av arbetsskyldigheten genom anstĂ€llningsavtal och omreglering av anstĂ€llningsavtal. För att införa trĂ€ning pĂ„ en kollektiv nivĂ„ kan det göras antingen genom kollektivavtal eller genom arbetsledningsbeslut (om det finns en koppling till arbetsgivarens naturliga verksamhetsomrĂ„de). Vad gĂ€ller personlig integritet mĂ„ste arbetsgivaren beakta att eventuella uppgifter som samlas in vid arbetstagarnas trĂ€ning behandlas enligt personuppgiftslagen. TrĂ€ning kan ses som en kompletterande del till arbetsmiljöarbetet och nĂ€r trĂ€ning införs sĂ„ bör ett helhetsperspektiv pĂ„ arbetsmiljön beaktasIn the context of some employers introducing mandatory exercise for employees, the aim of this thesis is to explore the extent to which employers can order their employees to exercice during working hours. Focus is on investigating how exercise can be introduced as part of work obligation and how the employer should take into account their responsibility for the working environment, as well as the limits on employees’ privacy. The conclusions are as follows: Exercise may, under certain conditions, be introduced as part of work obligations through individual contracts and re-regulation of contracts. Exercise can be introduced on a collective level, through either collective bargaining or management decisions (if there is a connection with the employer's business area). In regards to privacy, the employer must take into account that data collected during employees’ exercise is dealt with under the Personal Data Act (personuppgiftslagen). Training can be seen as a complement to the employer taking measures in regards to work environment and there needs to be a holistic perspective on the working envorinment when employee exercise is implemented

    Abstract The aim of this research was to peruse the verdicts of custody disputes were violence against the mother has occurred. In 2005, a study by Barnombudsmannen presented a result that showed that 43 % of custody disputes were domestic violence occurred was convicted joint custody. The result leaded to a restriction of Swedish family law in 2006. This study therefor aims to examine how the court motivates their decisions in custody issues today. In the accurate Swedish section of family law the central purpose is to see to the childÂŽs best interest. On the one hand the court must judge the risk of abuse posed to the child or anyone close to it, furthermore the importance for the child to have a close relation to both caregiver. This was done by studying 379 court verdicts from three different courts between 2011 and 2013 in which parents did not agree on custody. In 19 of these court verdicts, domestic violence occurred. The research showed that there are numerous factors in custody disputes that are important and affects the district court's assessment of the custody issue. The childÂŽs best interest is an individual and complex concept and it is therefore difficult to make any generalization of what is required to enable the district court judge for joint or sole custody. The study showed that in 26 % of our cases, the court judged for joint custody. This shows a decrease in judging joint custody maybe as an effect of the change of law in 2006
