Distributed Computing in Peer-to-peer Networks

Ahmetspahic, Emir January 2004 (has links)
<p>Concepts like peer-to-peer networks and distributed computing are not new. They have been available in different forms for a long time. This thesis examines the possibility of merging these concepts. The assumption is that non-centralized peer-to-peer networks can be used for effective sharing of computing resources. While most peer-to-peer systems today concentrate on sharing of data in various forms, this thesis concentrates on sharing of clock cycles instead of files.</p>

Arbetsomfördelning inom offentlig sektor : En fallstudie kring hur minskad arbetsbelastning påverkar upplevelsen av stress, motivation och kvalité / Job distribution in public sector : A case study about how reduced workload affects the experience of stress, motivation and quality

Lannemyr, Hanna, Bergh, Ellen January 2018 (has links)
Bakgrund och problem: Under de senaste årtiondena har kostnadseffektivisering inom den offentliga vårdsektorn inneburit förändringar vilket ökat arbetskraven i form av fler arbetsuppgifter i förhållande till tillgängliga resurser. Kombinationen av hög arbetsbelastning, tidspress och ökad vårdtyngd är bidragande faktorer till ökad stress, minskad motivation samt bristande kvalité inom vården. Författarna till föreliggande studie ser en avsaknad i forskning kring hur en minskad arbetsbelastning påverkar medarbetares upplevelse av stress, motivation och kvalité, därav behandlar studien detta område. Syfte och metod: Syftet med föreliggande studie är att undersöka medarbetares upplevelser av faktorerna stress, motivation och kvalité efter införandet av en arbetsomfördelning vilket gett en förändrad arbetsbelastning. Genom en kvalitativ metod har författarna till studien med hjälp av semistrukturerade intervjuer undersökt vad konsekvenserna kan bli då en period av hög arbetsbelastning åtgärdas genom en omfördelning av arbetsuppgifter till en minskad arbetsbelastning. Resultat: Före införandet av arbetsomfördelningen beskrev respondenterna en arbetssituation som var tidspressad, hade hög arbetsbelastning, högt patientantal samt att mycket tid lades på arbetsuppgifter som inte direkt rörde patienter och administration vilket är vårdpersonalens kärnuppdrag. Efter arbetsomfördelningen upplevdes förbättringar i arbetsbelastningen då kringuppgifter togs bort från vårdpersonalen. I föreliggande studie framgår att arbetsomfördelningen resulterat i mer fokus på kärnuppdraget samt ökad kontroll över det egna arbetet. Analys och diskussion: De faktorer som tidigare studier lyfter som riskfaktorer är genom arbetsomfördelning inte lika överhängande hos de studerade arbetsgrupperna. Genom en minskad arbetsbelastning visar föreliggande studie att stressnivån har blivit lägre, motivationen har till viss del ökat samt att den upplevda möjligheten att leverera kvalitésäker vård har förstärkts. Slutsats: Genom tidigare studier samt föreliggande studies empiriska material kan det antydas att en minskning i arbetsbelastning ger positiv inverkan på vårdpersonalens upplevelse av stress, motivation och kvalité. / Background and problem: Over the past few decades, cost efficiency in the public health sector has resulted in changes, which has increased labor requirements in terms of more tasks in relation to available resources. The combination of high workload, time pressure and increased care loading are contributing factors to increased stress, reduced motivation and lack of quality in health care. The authors of the present study see a lack of research on how a reduced workload affects employees' experiences of stress, motivation and quality, hence the study deals with this area. Purpose and method: The purpose of the present study is to investigate employee experiences of stress, motivation and quality factors following the introduction of a job distribution, which resulted in a change in workload. Through a qualitative method, the authors of the study, using semistructured interviews, examined what the consequences may be when a period of high workload is remedied by redistributing tasks to a reduced workload. Results: Before the introduction of the job distribution, respondents described a workload that was time-stressed, had high workload, high patient numbers, and a lot of time spent on tasks that did not directly affect patients and administration, which is the healthcare personnel's core assignment. With the job distribution, improvements in workload were experienced when circumcision data was removed from healthcare personnel. The present study shows that the job distribution resulted in more focus on the core assignment and increased control over their own work. Analysis and discussion: The factors that previous studies raise as risk factors are not as consistent with the workgroups through job distribution. Due to a reduced workload, the present study shows that stress levels have been lower, motivation has grown to a certain extent, and that the perceived opportunity to deliver quality assurance has been strengthened. Conclusion: Through previous studies and empirical material of the present study, it can indicate that a reduction in workload gives a positive impact on the healthcare personnel's experiences of stress, motivation and quality.
