Horse flies and other biting Diptera are not only annoying pests, but can inflict numerous diseases on the people and animals they bite. Studies in recent years have shown horse flies are less attracted to striped surfaces, providing evidential support that zebra stripes have evolved as biting fly protection. The Omo River Valley tribes in the historical zebra range of southwest Ethiopia regularly
Fysiska förändringar i redan bebyggda områden har i vissa fall visat sig vara problematiskt, inte minst med hänsyn till påverkan på det sociala livet. För att möta behovet av den ökade befolkningen i Sverige idag är förtätning ett alternativ för att inte ta värdefull mark i anspråk, vilket innebär att det byggs tätare och högre i redan bebyggda områden. Vid sådana fysiska förändringar är det därföWith the need for housing in Sweden high and steadily growing, there is now more emphasis than before on urban expansion in cities. Built areas consist of social relationships, structures and contacts which can be described as social risks when they lead to negative effects. Social effects are altered by changes in the physical environment, which is why it is essential to properly plan out these e
Background As new product development is becoming more important due to higher and more global competition the new product introduction process needs to be efficient in order to launch new products before they become obsolete. Therefore, a more efficient development process with integrated functions is needed. Concurrent engineering claims to be this and has support in much research. However, conc
Background Activity-Based Costing is a costing method arisen in 1980’s as a response to changed cost structures. As business had become less labour intensive, Kaplan and Johnson argued that the traditional management accounting methods, using direct labour as cost base, were out-dated. Instead, Activity-Based Costing is based on the costs for the activities that the products require. The methodolo
Fallföretaget har, vid starten av examensarbetet, bestämt sig för att träda in på hotellmarknaden. Götessons är idag en etablerad aktör på kontorsmarknaden, men de ser att det kan finnas risk för att efterfrågan på deras produkter avtar på den här marknaden. De har planerat att etablera sig på hotellmarknaden genom att använda sig av tillväxtstrategin marknadsutveckling, alltså genom att använ
Examensarbetets uppsats beskriver en produktutvecklingsprocess, syftet är att utveckla ett produktkoncept för en övervakningskamera i en hissmiljö. Studien är genomförd på uppdrag av Axis Communications AB, ett marknadsledare företag inom nätverksvideo. Uppsatsen inkluderar en omfattande bakgrundsstudie, i vilken syftet är att skapa förståelse för relevanta delar av hissbranschen för att få kunskThis master thesis describes a product development process with the aim of developing a product concept for a surveillance camera in an elevator environment. The study is conducted on behalf of Axis Communications AB, a market leading company in network camera solutions. The thesis includes a comprehensive background study that seeks to understand relevant parts of the elevator business to gain k
Date of Seminar: 2018.01.11 Supervisor: Devrim Göktepe-Hultén Key words: Change management, change process, Shape 2020, Shape & Share Purpose: The purpose of this thesis is to investigate how Cramo AB works with change management and if they succeed or not, by using Kotter’s model as an analytic tool and other theoretical perspectives of change management. Methodology: The research is con
In this Master's Thesis x-ray tomography was used during tensile experiments on paperboard to study delamination and cohesive failure. Digital volume correlation of the x-ray tomograph images enabled quantitative analysis of strain fields. Tensile experiments on different specimen geometries were also conducted to investigate how the geometry affected the response of the specimens during load
Vi identifierade faktorer som alla intervjuade företag har gemensamt i termer av struktur, värde och till sist värde genom struktur. Exempelvis utför företagen sitt förändringsarbete snarligt varandra (struktur), lojalitetsprogrammen skapar mer återkommande kunder i samtliga fall (värde) och samtliga fall har samarbetspartners för att öka värdet för kunden (värde genom struktur).We identified factors that all interviewed firms have in common in terms of structure, value and lastly value through structure. For an example, all cases conduct their change processes in a similar way (structure), the loyalty programs create more returning customers for all cases (value) and all cases have cooperation partners that increase the value for customers (value through structure).
Celler som modeller Parkinsons sjukdom är en neurologisk åkomma som mestadels drabbar den äldre befolkningen. Proteinet alfa-synukelin tros ha stor påverkan på mekanismer i hjärnans celler och således på sjukdomsprocessen. För att bota denna sjukdom krävs därför mera forskning om alfa-synukelin. I detta projekt har celler använts för att undersöka detta. Parkinsons sjukdom uppstår på grund av aParkinson’s disease (PD) is considered one of the most frequent neurodegenerative disorders amongst elderly people. PD leads to loss of dopaminergic neurons in substantia nigra of the brain giving symptoms such as slowness of movement and dementia. PD brains have been found to contain accumulations of a protein named alpha‐synuclein (α‐syn). Additional to its aggregation propensity in PD it is als
The area of wooded pasture in Europe has decreased drastically over the last centuries due to abandoned management. Herrevadskloster is a newly formed nature reserve in northern Scania with an unusually long continuity of being an open, grazed woodland containing large old trees. In this study, the reserve was studied to evaluate its potential to further the conservation of the redlisted saproxyli
Denna kandidatuppsats kartlägger med hjälp av en kvalitativ intervjustudie vilka förutsättningar HR-avdelningen på Sparbankens Skåne anser som väsentliga för deras möjlighet till att fungera väl. Studien har genomförts med hjälp av ett hermeneutiskt perspektiv och en abduktiv ansats. Med hjälp av fem semistrukturerade intervjuer samlades empiriskdata in för att sedan analyseras med hjälp utav kodn
After the discovery of graphene in 2004, a single layer of graphite, the assembly of 2D materials became a promising research area in solid state Physics. This thesis explores fabrication of 2D-heterostructures that aim to probe into graphene’s electronic structure with the Tunneling Field Effect Transistor (TFET). In the fabrication process, we used mechanical exfoliation to obtain monolayer gra
Proactive interference is the phenomena where previously learned information interferes with the learning of new information, causing a reduction in retrieval of the new information. This phenomenon is studied with the AB/AC paradigm, in which participants encode two word-pair lists (B/C) that share a common word-cue (A). The common finding in studies using this paradigm is a reduced accuracy for
This thesis aims to investigate to what extent the principles of the Human Development and Capability Approach (HDCA) are reflected in Fair Gold Mining (FGM). The Fairmined certification of the Alliance for Responsible Mining (ARM) is taken as a case study. The principles of the HDCA are based on the idea of achieving people-centered development by promoting capabilities and a better quality of li
Purpose: The purpose of the study is to further contribute on the theory of dynamic capabilities, integrated in the resource-based theory, by investigating how resources generate dynamic capabilities. Furthermore, the study aims to investigate how the resources and dynamic capabilities affect a company's ability to survive over time. Methodology: The study is a multiple-case study with an abd
This thesis evaluates the success of a fundamental investing strategy on the Swedish stock market between 2004 and 2016. The main purpose is to examine if the F_Score system developed by Piotroski (2000) could be used to identify winners and losers during aforementioned time frame. A lot of research has previously been conducted on the topic of fundamental investing and some focusing on F_Score. T
