This bachelor's thesis is about odd perfect numbers and some of the conditions and characteristics they have if they exist. Both classical results and contemporary proofs from newer articles are included. Also history about the results and the mathematicians who managed to prove those and some of today's research and results are contained.

Directive 2001/23/EC on the safeguarding of employees’ rights in the event of transfers of undertakings, aims primarily to protect employees from being placed in a less favourable position solely as a result of a transfer of an undertaking. Article 3(3) of the Directive, more particularly, provides that, upon a transfer of an undertaking, the new employer is bound by terms and conditions agreed in

Problem area: Ecosystem services, the benefits that people obtain from nature, are essential for human well-being, but are declining globally. Even though research on ecosystem services has increased in the last decade, knowledge on cultural ecosystem services (CES), which are the non-material benefits people gain from ecosystems, is still limited. Wine production shapes special landscapes that pr

Twitter har beskrivits som ett relevant verktyg för svenska politiker för att hålla sig uppdaterade kring vad som händer inom den politiska världen. Twitter som kanal har tidigare benämnts som ett elitmedium, då det finns en stark närvaro av opin-ionsbildare av olika slag. Det är alltid viktigt att granska makthavares kommuni-kation och hur detta kan påverka demokratin. Vi har genomfört en kvalitaTwitter has been described as a must-have tool for Swedish politicians, to not fall behind in the constant flow of information. Previous research has defined Twitter as an elitist channel, due to its dense population of opinion-makers. It is important to keep a critical approach towards how people in power communicate and what possible effect their communications might have on the democratic proce

Women in developing countries have been and are still suffering from various disadvantages on the labor market. We use a fixed effects model with a hierarchical structure to assess the empirical relationship between economic integration, measured by trade, exports and imports, and the female labor force participation rate (FLFPR). The relationship between economic integration and the female employ

The report investigates the use of measured transversal vibrations to estimate the axial load on beams/columns. A literary review of the basic theory is performed, which clearly shows the theoretical relation between natural frequency and axial loading of linear structural elements (strings & beams). Current journal articles show that research has been done on mathematical models as well as so

This essay aims to analyze Australia’s ambivalent relationship towards the asylum seeker in general, boat people in particular, using the theoretical framework of institutional panic, as formulated by Blum and ‘securitization’, as developed by the Copenhagen School. It outlines the country’s past and present relationship with migration, while focusing its analysis on events preceding and following

This paper investigates the feasibility of OCA for ASEAN after the implementation of ASEAN Economic Community Blueprint in 2008. Dynamic Conditional Correlation (DCC) model with and without a structural break are used to identify whether the policy implemented facilitates the region to move closer to a single currency area.

Det relativt sparsamma utbudet av ordoviciska blottningar i Fågelsångsdalen, Skåne, krävde en borrkärna för att lära mer om lagerföljden. Borrkärnan har, under arbetet med denna rapport, studerats och dokumenterats litologiskt, litostratigrafiskt och till viss grad paleontologiskt. Fågelsångskärnan-2 består av mörka skiffrar avsatta i relativt djup marin miljö med rikt innehåll av bland annat grapOrdovician strata are well represented in the Fågelsång valley in south-central Scania (Skåne), southern Sweden, but exposures of such deposits are relatively few and most of the present outcrops are small. In order to study a stratigraphically more complete succession from the area, a core drilling, here referred to as Fågelsång-2, was conducted in 2013. The drilling was stopped at a depth of 64,

Bakgrund: Det första intraoperativa mötet är oftast kort och det är viktigt att anestesisjuksköterskan får en god kontakt med patienten. Organisatoriska aspekter kan påverka mötet genom ett pressat tidschema. Tidigare forskning kring oro är ur ett patientperspektiv. Därför är det av vikt att belysa anestesisjuksköterskans upplevelser. Syfte: Syftet var att belysa anestesisjuksköterskors upplevel

This thesis examines social change and the collective trauma for women in Ukraine after the collapse of the Soviet Union by investigating general subjective wellbeing at the intersection of gender, generation and ethnicity. It argues that women had a special position during and after the Soviet regime due to the existing familialistic discourses both in the Soviet Union and independent Ukraine, an

Titel: Intranätets nya ansikte. Författare: Lisa Naess och Sarah Mesch. Handledare: Johanna Stenersen. Syfte: Syftet med den här uppsatsen är att studera hur organisationer balanserar formell och informell kommunikation i en centraliseringsprocess av sitt intranät. Metod: Vi har genomfört en kvalitativ studie med semistrukturerade intervjuer samt officiella dokument som grund. Slutsats: Vår studie

The purpose of this thesis is to explore the possibility of asymmetry in the dynamic conditional correlation of stock returns and gold returns. We hypothesize that this asymmetry might be different for large and small firms, as a result of size specific characteristics that may influence firm profitability and risk following negative market shocks. We investigate this on three different sized U.S.

På grund av det kommunala självstyret och kommunens beskattningsrätt, argumenteras det för att kommuner sinsemellan har blivit platsbundna konkurrenter om icke platsbundna hushåll och företag. Trots den konkurrenssituationen finns det flera exempel som visar på att kommuner samverkar för att skapa attraktivitet och utveckling i sin delregion, vilket inte minst märks i de svenska storstadsregionern

The importance of reading : a Master’s Thesis about literacy and librarians’ motivational reading strategies towards children and teenagers. The public literacy debate has exploded all over Swedish media since PISA published their report at the end of 2013 with the result that politicians, teachers and parents suddenly have shown a lot more interest in what and how young people read. The report h

Bisphenol A (BPA) is an endocrine disruptor which is very present in our surrounding environment. As a component mainly used in plastics and in the inner linings in cans, BPA can also be found in our bodies due to migration into food. Once the substance is reaching the components of the body it is biotransformed into a more water soluble molecule called monoglucoronide. Whether to measure the unco

This thesis gives an introduction to the basic formalism of one-dimensional supersymmetric quantum mechanics. The factorization of a Hamiltonian is used to create a supersymmetric partner Hamiltonian. The connections between the energy spectra and wave functions of these partner Hamiltonians are deduced and examined for the case of broken and unbroken supersymmetry. An extension to hierarchies of

Over the past few years, there has been considerable academic interest in studying the relationship between China and Africa. This study aims to describe what effect Chinese outbound foreign direct (OFDI) investments and private companies have had on employment opportunities and industrialization in Ethiopia. The research question reads: What effect has Chinese outbound foreign direct investments

I Sverige råder sedan en tid tillbaka en debatt kring huruvida ett könsneutralt ord bör användas för att undvika benämning av kön i diverse sammanhang. Syftet med denna undersökning var att utvärdera hur ordet hen bedöms i rekryteringssammanhang, i jämförelse med den sökande. Studien genomfördes med en kvantitativ undersökning i form av en experimentell design. 160 deltagare fick läsa en av två joThere is currently an ongoing debate in Sweden whether a gender neutral pronoun should be used to avoid specific gender associations. The purpose of this thesis has been to evaluate if the gender neutral pronoun hen in comparison with the applicant in a recruitment process can be considered as more gender neutral. The study was conducted using an explorative quantitative method. 160 participants r
