Kommersiella Fastighetshyror och Finansiell Stabilitet
In recent years, global organizations safeguarding financial stability has started to track commercial property markets. One of the reasons for this refers to the fact that commercial property constitutes a large share of bank lending. Simultaneously, bank exposures to commercial property are extensive and risky since collateral values are strongly correlated to borrowers cash flows. Since banks are viewed to play a key role for financial stability, studying the relationship is well motivated. To better understand how commercial property markets interact with financial stability, this paper develops an econometric model for studying the commercial rental market.
Towards a function for an Arabidopsis protein involved in sucrose dynamics
System based models of plants rely on descriptions and assigned functions of genes, and currently 50% of the genes in Arabidopsis thaliana has either no assigned function or a function based on homology only. Mitogen activated protein kinases (MAPK's) are key players in cell signalling and are conserved among eukaryotes, though their targets are highly diverse. A recent study has described a small Arabidopsis protein (80), without homology to any described protein, as a phosphorylation target of the MAPK's MPK3/6. Further work established ?-glucan phosphorylase (PHS) as interacting with 80 and described a delayed senescence phenotype for 80 knock-out plants.
On the hunt for improvements : possibilities of increasing welfare in captive cheetahs through hunting enrichment
The cheetah (Acinonyx jubatus) is one of the big feline species kept in zoos worldwide. The wild populations are quite small and therefore the captive population make up an important part of the total population of the world. Although life in the wild is not always easy and a captive environment provides shelter and food it does not come without problems. In captivity cheetahs become chronically ill and also develop stereotypic behaviours. Neither of these are problems in wild populations and both can be linked to stress in captivity.

Bland annat analys av precisionsgjutning i zink, ett förslag som redan var under diskussion på företaget.
How Maasai settlements affect the grazing habits of the Common Hippopotamus (Hippopotamus amphibius) in the Maasai Mara National Reserve, Kenya
With a growing human population as well as a changing lifestyle, the conflict of wildlife and humans is intensifying. In Kenya, Maasais and their livestock have for a long time coexisted with wildlife, but an adjustment to privately own land and cultivation might rapidly change the terms for this coexistence. To understand how the Maasais and their livestock affect the wildlife in the Maasai Mara National Reserve and the surrounding area, this study was undertaken. The purpose of this thesis is to examine how hippos are concerned..
BROTTSPREVENTION I EUROPA En kritisk komparativ diskursanalys av brottsprevention riktat mot ungdomsbrottslighet i England och Sverige
This thesis investigates how crime prevention is represented with the aim of preventing and
reducing youth crime in two crime prevention strategies for Croydon in England and Stockholm
in Sweden for the period 2022-2026. The aim of this thesis is to contribute to increased
knowledge and deeper understanding about how crime prevention is represented by prevailing
discourse in policy documents against juvenile delinquency in Europe by conducting a
comparative analysis. The study was conducted based on Carol Bacchi?s theory ?What?s the
problem represented to be?. Three adapted questions from the WPR approach were translated
to critically discourse-analytically examine two policy-oriented strategies against youth crime
on local level in Croydon and Stockholm.
Uppdraget möter verkligheten : En essä om korstrycket på pedagoger
This essay is about the meeting of the pedagogic mission and the reality of the conditions in preschools. It is about the frustrations that I, as a pedagogue, experience when I cannot fulfill this mission. An example of this is working when understaffed.My purpose is the acknowledgment of two main areas of the curriculum: caring and learning. This essay demonstrates the diversity of the occupation and it ?s constant need of positioning.
En skildring av hur tredje världen framställs inom ett urval av västerländsk barnlitteratur utifrån en postkolonial teori : En kvalitativ textanalys
In recent years, the characterization of the Third World and its inhabitants in West-originated children?s books has been subject to debate. Media attention around a selection of books has generated discussions on how this relates and aligns with Sweden?s national teaching curriculum. The objective of this study is to explore how a selection of authors, born in Western countries, have characterized and presented the Third World and its inhabitants in its literature.
Motivation bland v?rnpliktiga n?r v?rldsordningen f?r?ndras: En intervjustudie om hur v?rnpliktigas motivation till fortsatt yrkesmilit?rt arbete p?verkas.
This study takes its starting point in ongoing changes and differences in the global power dynamics. The liberal rules-based world order that has been acknowledged for governing the world with the US as the hegemon of power has been strongly challenged during the last decades. Russia?s invasion of Ukraine can be seen as an example of ongoing changes in the world order, with Russia as a challenger to the US as the hegemon of power. The changes and instability that this has led to for Sweden's national security situation can be seen as a concrete example of how ongoing changes in the world order affect Sweden?s foreign policy.
Vaccination mot Humant Papillomvirus - vem bör vaccineras?
Background: Infection with Human Papillomavirus, HPV, is one of the world's most common sexual transmitted infections. The virus causes genital warts (condyloma) but certain virus types can cause cancer. The most common cancer type caused by the virus is cancer of the cervix. Nowadays there is a screening program for women between 23 and 60 years of age where Pap smears of the cervix is taken to discover abnormalities at an early stage. Cervical cancer is very common all over the world and this screening program saves many lives, but not in the less developed countries since the screening program is too expensive.
Design av stimuligenerator för radarmålsökare
During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.
The vertical farm : varför har idén uppkommit och hur är den tänkt att fungera?
By immersion in the situation of the food production today and a historical study of how past development has led us to this point, one goal of this essay is to discuss whether the current way of farming can be applied in a sustainable future. Another objective of the essay is to study the vision Vertical farming as an alternative approach, and to focus on different aspects of this phenomenon in order to provide as comprehensive a picture as possible.The paper, thus, seeks to broaden the views for alternative approaches regarding a well-established method which we often take for granted. The aim is also to initiate a discussion around the need to also take radical ideas in regard if we want to face the future in a sustainable manner. The method is a qualitative literary study where scientific articles and papers have been used to discuss the issues: why has the idea of Vertical farming arisen, what is Vertical farming and how is the Vertical Farm meant to operate? Does Vertical farming have a place in the sustainable city of the future? For a long time us humans lived as one with nature, in a symbiotic relationship in which we gave and took as a functioning part of an ecosystem.
Minskad utbredning av apollofjäril, Parnassius apollo, i södra Stockholms län : En studie av möjliga faktorer utifrån artens habitatkrav
The Apollo butterfly, Parnassius apollo, is categorized as Near Threatened (NT) in IUCN Red List. Today in Sweden it is found only in strongly fragmentized populations. In the county of Stockholm, P. apollo exists exclusively in some islands of the archipelago and with one mainland population in Stora Vika. This study has the purpose of expanding the knowledge of the local conditions for the butterfly in the south parts of the county of Stockholm and thereby contributes to a sustainable land management that can preserve the Apollo butterfly.A comparative study was done between areas where the butterfly today have: a stable population (Stora Vika, Utö and Ålö), has disappeared (Muskö and Yxlö) or is strongly declining (north part of Ornö).
