Forskning om arbetsrelaterad stress och coping är viktig eftersom det påverkar upplevd hälsa. Forskare anser att man bör studera hälsofrämjande faktorer och ge förslag på åtgärder för att minska stress som annars orsakar stort individuellt lidande och kostnader för samhället. Utifrån ett salutogent perspektiv fokuserade denna studie på långtidsfriska undersköterskor på ett akutsjukhus och hur de upplevde stressiga situationer, vilka copingstrategier de använde och förslag på åtgärder för att förbättra arbetssituationen. Åtta halvstrukturerade intervjuer genomfördes, tolkades och bearbetades enligt ett induktivt tematiskt analyssätt. Undersköterskorna beskrev tre övergripande stressorer: tung arbetsbörda, brister i arbetsorganisationen och personalkonflikter vilket är kännetecken för arbetsuppgifter med stora krav och litet kontroll.

Syftet var att genom en deskriptiv litteraturstudie identifiera troliga stressorer bland sjuksköterskor i deras yrkesverksamhet på sjukhus i Europeiska länder samt vilka copingstrategier de använder sig av för att hantera stressen. Vidare var syftet att undersöka vilken relevans undersökningsgruppen har i förhållande till valda artiklars syfte och frågeställningar. Ur de 14 granskade artiklarna utläste författarna tio olika grupper för stressorer vilka i storleksordning med den mest förekommande/vanligaste var ?Relationer?, därefter följer i fallande ordning; ?Kontroll?, ?Osäkerhet?, ?Arbetskrav/överbelastning?, ?Personliga förväntningar/tvetydighet?, ?Arbetsmiljö?, ?Emotionella påfrestningar?, ?Arbetsledning?, ?Tidspress? samt ?Missnöje?. Ur sex av de granskade artiklarna kunde författarna utläsa vilka copingstrategier som användes, vilka var olika typer av känslofokuserad- och problemfokuserad coping.

Varje år insjuknar i Sverige omkring 50 000 människor i cancer. Det innebär att ungefär var tredje svensk kommer att drabbas av cancer under sitt liv. Ett cancerbesked framkallar starka känslor hos patienten. För att kunna bemästra känslorna samt hantera situationen tillämpar patienten någon form av coping. I svensk forskningslitteratur beskrivs coping som vad en person gör för att handskas med olika stressorer i vardagen samt vilka resurser personen i fråga har för att ta sig an problemen.

Domestication has resulted in the ability for animals to adapt to environments created by the human over time. The behavior differs very little between wild and domesticated animals, but the difference seen is how often and to what degree a behavior is performed. The need for efficiency in modern animal production has led to welfare problems in the productionsystems where the animals have difficulties coping with their environment. Attempts to environmentally adapt individuals by selection for reduced frequency of natural behaviours have been made. These have shown that natural behaviours are complex and are controlled by several different mechanisms, making selection for reduced natural behavior difficult, and it may also lead to unwanted and abnormal behaviours.

The purpose of this thesis is to explore and analyze the processes and efforts involved in rebuilding the war-torn state of Afghanistan. The examined period span from the fall of the Taliban regime in 2001, to the elections in 2005. This period, commonly known as the Bonn-process, sets out the initial time for the reconstruction of the state.A theoretical framework, which considers the necessary mechanisms for successful state-building, will be used to analyze Afghanistan's re-building process. The mechanisms include the prerequisite of a stable security environment, emerging from a cease-fire, together with the development of a well-functioning economy, re-introduction of rule of law and rejuvenating civil society.The failure to establish a secure environment has had a devastating impact on all analyzed aspects of the re-building process. It is therefore crucial that the international society continuing to assists the Afghan government in its efforts to strengthen its capacity, in order to improve the security situation.

The increased frequency of reported Methicillin-resistant Staphylococcus pseudintermedius (MRSP) is of great concern to small animal healthcare due to limited options of antimicrobial therapy. The aim of this literature study is to investigate 1) characteristics and classification of S. pseudintermedius, 2) resistance mechanisms and emergence of MRSP, 3) risk factors for selection of MRSP, and 4) clonal distribution around the world. S. pseudintermedius is a skin and mucosal commensal in healthy dogs and cats, but can cause infections, including pyoderma. Beta-lactam antibiotics inhibit bacterial growth by binding to the penicillin binding protein (PBP), a vital enzyme in the synthesis of the bacterial cell wall.

The purpose of this study was to examine how school counselors in a specific municipalityviewed their work situation, if they experienced stress and how they would handle that stress.Five school counselors out of eight in the specific municipality participated in qualitativeinterviews where they could describe their feelings and thoughts. Their experiences wasexamined and analyzed with the theories of coping and empowerment. The results showedthat there were unhealthy levels of stress in the profession amongst the five counselors. It alsoshowed that the uttermost reason for the experienced unhealthy stress was the feeling of notbeing able to give as much time and help to the pupils as they want and need. The reason forthis was that an increasing number of pupils were, and are, experiencing unhappiness and arein need of seeing the school counselor.

How effective is consumer power? Can consumers regulate corporate behavior?And if so is the case, could the mechanisms where consumers regulate corporatebehavior have any democratic value to contribute with? These are the questionsthat this master's thesis comprehends with. The purpose of this writing is toconstruct a theory of consumer power that is compatible with democratic theory,this in order to contribute to the ongoing discussion within the discipline ofpolitical science about the third democratic transformation. A discussion that hasbeen actualized due to the democratic deficit created by the growing corporatepower and the shift of power from state to private enterprises. Besides showingfor a parallel between the democratic mechanisms that exists in the relationbetween citizens and state on the one hand, and the consumers and corporationson the other hand, this paper argues that consumers do have a great potential inregulating corporate behavior towards a higher social responsibility andawareness.

Det svenska samhället blir alltmer mångkulturellt. I och med den ökade invandringen behöver hälso- och sjukvård uppmärksamma kulturens betydelse för patienters hantering av sin sjukdom. Utan förståelse för individers kulturella värderingar är det svårt för vårdpersonal att förstå hur individers copingmönster påverkas vid ohälsa. Syftet med litteraturstudien var att belysa hur kulturella hälsoövertygelser kan påverka människors copingmönster vid ohälsa. Till resultatet användes 13 artiklar (elva kvalitativa, en kvantitativ samt en som var både kvantitativ och kvalitativ) som granskades och analyserades.

AbstractOil rich states all over the world share a common feature. They are less likely than other states, depending on other resources, to be ruled democratically. In this essay Saudi Arabia has been studied with the purpose of trying to find which mechanisms that lie behind why oil rich states do not have institutions or institutional change that promotes democracy.Saudi Arabia has the world's largest known reservoir of oil. The oil brings huge revenue each year to the Saudi Arabian government. Why have Saudi Arabia not developed democratically when their economic growth suggests that to be a natural step? Under the framework of historical institutionalism and path dependency theory, I have used process tracing trying to track the mechanisms behind Saudi Arabia's authoritarian rule down.
