Internetbedrägerier ? utsatthet och den upplevdasäkerheten vid internetanvändning bland studenter

Internetbedrägerier är ett växande problem som kan leda till negativakonsekvenser för offren och den kommersiella infrastrukturen. Attkartlägga fenomenet och identifiera de egenskaper som kan bidra tillökad risk för utsatthet är därför viktigt. Syftet med denna studie var attundersöka utsattheten och oron för att utsättas för internetbaseradebedrägerier bland studenter vid Mittuniversitetet. En webbaseradenkät distribuerades till 600 slumpmässigt utvalda studenter ochdatamaterialet (17%, N = 102) analyserades genom ?², Mann-WhitneyU och Kruskal-Wallis-test samt logistisk regression.

Att leda - N?r juridiska krav kolliderar med personliga v?rderingar

This study aims to analyze the effects of the proposal regarding mandatory reporting for undocumented individuals within the Swedish public sector and how this potentially affects leaders in their efforts to motivate their employees to comply with this requirement, which is considered ethically charged. The primary focus is to understand how these leaders can motivate their employees considering legal requirements that are both legally binding and ethically sensitive. By interviewing leaders from various sectors within the public domain in multiple Swedish municipalities, this case study seeks to highlight the challenges arising from the amalgamation of legal mandates and ethical dilemmas. Its goal is to provide insights that can support these leaders in their complex decision-making regarding such issues. The study addresses theoretical aspects such as change management and critical organizational theory. The study's findings indicate that political decisions play a pivotal role in the processes of change within public operations. Resistance to change varies and takes various forms.

Hedgefonder : En empirisk studie om olika hedgefondstrategier och deras påverkan på avkastning

Investment in hedge funds is a relatively new phenomenon for investors compared with other forms of savings. In recent years, the interest has increased among investors in investing their money in hedge funds, given the protection against declines in the market they are aiming for. Their main purpose is to generate a high return at a low risk regardless of market trends. This they can achieve by having fewer restrictions that offer more flexible investment strategies and freer investment opportunities.The purpose of this paper is to identify how the selected hedge fund strategies have performed during the recent economic downturn. We also want to clarify the claim that hedge funds exhibit a positive absolute return regardless of what the market is performing.In order to answer the purpose of the essay and its problems, we have used a quantitative method with a deductive approach in the processing of data.

Examining the social component of sustainable forest management in Prince Albert and Vilhelmina Model Forests

Due to the forest industry downsizing, many communities in rural forest regions in Canada and Sweden are facing problems to survive. In order to create community sustainability, resilience and well-being in remote forest regions, the view on the forest resources has shifted towards multiple use, through the concept of sustainable forest management (SFM). Beside the economic and ecological elements of sustainability, the social forest values are needed, contributing to the human well-being, local participation, stakeholder collaboration, human rights and cultural connection. In this thesis the embodiment of the social component of SFM within Prince Albert Model Forest (Canada), and Vilhelmina Model Forest (Sweden) will be examined. Being partners and facing similar challenges as rural boreal forest regions, the two model forests are compared through analysis of projects and activities, conducted interviews and organization documents. Looking at projects mentioned as successful by the interviewees, they all have elements from the social values of SFM. The direction can be explained by the introduction of the Forest Communities Program in Canada, demanding the Model Forests to work towards community stability and resilience, the Model Forest organization concept itself and the way global focus are increasing around social forest values. In the future, it may be important that the role of the MFs enable some kind of political authorization and legitimacy in order to improve conflict solving and indigenous rights equality.

Effekten av formativ bedömning : En studie kring effekterna av formativ bedömning i anknytning till kunskapssyn, problemlösningsförmåga och attityd

This essay examines if formative assessment causes any impact on upper secondary school students results in social science. Other questions asked are which group of students benefits most from formative assessment and if any connections can be found between the students result and their cognitive approach to learning, problem solving capability and attitude to school.Two classes from a school in Stockholm were chosen to participate in the study. The theoretical framework is mostly based on former research performed by Black and William (1998, 2003). Multiple methods were used, including an experiment with a parallel-group design with two groups, a survey and a problem solving test. Statistics is used to describe and analyze collected data.Both groups were taught during five lessons in the same field of knowledge with the same kind of teaching, apart from formative assessment.

Klassiska populationsmodeller kontra stokastiska : En simuleringsstudie ur matematiskt och datalogiskt perspektiv

I detta tvärvetenskapliga arbete studeras från den matematiska sidan tre klassiska populationsmodeller: Malthus tillväxtmodell, Verhulsts logistiska modell och Lotka-Volterras jägarebytesmodell. De klassiska modellerna jämförs med stokastiska. De stokastiska modeller som studeras är födelsedödsprocesser och deras diffusionsapproximation. Jämförelse görs med medelvärdesbildade simuleringar.Det krävs många simuleringar för att kunna genomföra jämförelserna. Dessa simuleringar måste utföras i datormiljö och det är här den datalogiska aspekten av arbetet kommer in.

Sexualiserade rykten - en del av vardagen? : En studie av några unga kvinnors förhållningssätt till rykten.

The purpose of this thesis is to understand the ways in which rumors affect the everyday lives of a few young women. The questions are: What kinds of rumors do the young women find are the most common? How do they respond to these rumors? Do the rumors affect their everyday lives and if so, how do they react to them? Do they resist them? Do they feel limited by them?The empirical data was collected through unstructured interviews (focus groups) with three groups. The groups discussed different themes without prompting questions by the interviewer and it was clear that rumors played an important role, in multiple ways, in the lives of the young women. The most common rumors were sexualized and were mostly concerned with the view that the young women should not engage in ?too many? heterosexual relations ? preferably none.

Manlighet i mellanstadiet : En kvalitativ studie om maskulina ideal bland pojkar i mellanstadiet

The aim of this study has been to examine, describe and analyze how masculinities can be represented and understood among boys in a Swedish primary school context. The study was conducted within a school located in a small community on the country side. Through the use of a qualitative research design we interviewed 13 boys from the fifth grade of this school, who all got to express and reason their perspectives of what it meant to them to be a boy in primary school and how that could impact their social life. For a wider understanding of the different dimensions of masculinity we used R.W. Connell's (2008) theoretical framework, hegemonic masculinity, which implies that there are multiple definitions of masculinities that are constructed in relation to each other in a hierarchical order.

Att vårdas i en flerbäddssal : En litteraturöversikt om patienters erfarenheter av att vårdas i en flerbäddssal

Bakgrund: Att vårdas i en flerbäddssal med andra medpatienter kan medföra både positiva och negativa erfarenheter för patienter. När en människa intar rollen som patient hamnar hen i en situation där patientens avskildhet kan bli svår att bevara och värdigheten kan bli hotad.Syfte: Syftet var att beskriva patienters erfarenheter av att vårdas i en flerbäddssal med andra medpatienter. Metod: En litteraturöversikt baserad på tio vetenskapliga studier, varav nio var kvalitativa och en var både kvalitativ och kvantitativ. Studierna som erhölls ifrån databaserna CINAHL och PUBMED analyserades och sammanställdes.Resultat: Resultatet presenteras i fyra huvudteman och sju subteman. Det första huvudtemat benämns som Att vårdas i en flerbäddssal med tre subteman; Betydelsen av att ha sällskap av medpatienter, Stödjande samtal av medpatienter och Bevara självständighet och värdighet genom ett oberoende. Det andra huvudtemat benämns som Patienternas upplevelse av att vistas i en flerbäddssal med andra medpatienter med ett subtema; Att vårdas i en könsblandad flerbäddsal som ett hot mot värdigheten.

Kapitalstruktur - Förklarande faktorer för variationen i svenska företags skuldsättning

Syftet med vår studie var att undersöka hur faktorerna tillgångsstruktur, lönsamhet, företagsstorlek och tillväxt kan förklara variationer i svenska företags skuldsättning. Studien syftade också till att undersöka skillnader i faktorernas förklaringskapacitet mellan olika sektorer. Utifrån tidigare studier och teorier om faktorernas förväntade relation till företags skuldsättning utarbetade vi egna arbetshypoteser över våra förväntade samband. För att analysera hur våra valda faktorer kan förklara variationen i företags skuldsättning utförde vi regressionsanalyser med två definitioner av skuldsättning som beroende variabel. Sammanlagt samlades data från 59 företag in för en tidsperiod på fem år som legat till grund för de utförda regressionsanalyserna.

Breeding practices of Red Maasai sheep in Maasai pastoralist communities

A survey was undertaken to understand sheep management, breeding practices and selection criteria for Red Maasai sheep in Maasai pastoralist communities in Kajiado District, Kenya. Differences between North and South Kajiado District were investigated to gain knowledge about farmers having different prerequisites and how it can affect the sheep production. The reason for keeping sheep and the specific breeds show the multiple objectives of the Maasai farmers. Adaptive traits, such as resistance to diseases and droughts, and productive traits, such as increased growth and carcass weight, were both ranked highly. In addition to this, the sheep has a social and traditional value in Maasai culture.

Produktivitetsanalys ur ett LEAN-perspektiv : En studie hos OPPC, AstraZeneca

The objective of this thesis is to map the resources and methods used at the department OPPC, at AstraZeneca, and derived from that give suggestions on possible solutions that will increase their productivity.Mapping of the product flow, as well as gathering of process data, has mainly been done using observations, but consultation with the process technicians has also played a great role. Further have theoretical methods been used, based on literature studies, within the areas of Lean production and statistics.The work has incrementally gone forward since the steps taken has been restricted by the irregularity of production which led to the need of creating a fictive production flow. This has affected the lead-time calculations in the way that they are meant to give an indication, rather than an absolute truth, on how different methods described shall be used.The current state analysis showed multiple areas of improvement when defining capacity as value adding time in relation to total throughput time. Using the "standard scenario" as a basis showed that the actual production flow only constituted 50% of the total project time. Further it showed that the workflow contained more non-value adding activities than value adding activities, which is a result of how the work is distributed within the department as well as in the different projects.

Påvisande av Helicobacter spp hos hund : en metodologisk studie

The purpose of this study was to develop a reliable molecular-genetic method to determine the different species of helicobacter in dogs. The study is part of a larger project to map the prevalence of Helicobacter spp in healthy and sick dogs in Sweden, and to determine the possible connection of Helicobacter spp infection with gastrointestinal diseases in dogs. Several published studies have reported on the prevalence of Helicobacter spp in dogs. The problem is that three of the most common species are so alike that a 16SrRNA-PCR with sequencing is not able to differentiate between them. In this study, DNA has been purified from samples and then a Multiplex PCR has been performed. Multiplex PCRs use multiple primers in one single PCR.

(H)elt om marsch!

The focus of this essay is on a political party that was founded in Sweden in 1904. Today, we known it as Moderata Samlingspartiet. Historically, this party has transitioned through multiple phases which have included a change of name and also a change of substance in the area of trade policy. The party that was cheering globalisation at the 2006 congress had its roots in protectionism and had been founded as a strict protectionist organisation. The question raised here is what has caused this dramatic change in the trade politic?In addressing this important question, I have used both organization and party strategy theories to identify the main underlying reasons.
