Zero Magic is a trick for the financial markets, which has the capacity to undermine the perceived value of a publicly traded company and profit from this. Short selling is a way of profiting from loss: Making money if and when a target company loses in value. It is a fundamental market activity that goes as far back as the first stock, yet to this day little is publicly known about the strategie
Purpose – In the last decade, greater attention has been paid to the role of management accounting and control (MAC) in making professional organizations more horizontal. The authors argue that earlier research has not shown how the interrelatedness between professional identities and MAC influences attempts to make organizations more horizontal. In this paper the authors respond to the call for m
The aim is to investigate the associations between economic stress in childhood and adulthood, and low generalized trust in other people, testing two life course hypotheses. The 2008 public health survey in Scania is a cross-sectional postal/mail questionnaire study in which 28,198 persons aged 18-80 participated (55% participation in the original sample). Logistic regressions were used to analyze
Background: A key innovation may allow one group of species to radiate and replace another, but the role of competition and background extinctions for the replacement process is vigorously debated and unclear. Questions: Is a minimum competitive advantage necessary to initiate replacement? Are background extinctions of the incumbent species necessary? What speciation and extinction dynamics charac
Polymorphic inversions are ubiquitous across the animal kingdom and are frequently associated with clines in inversion frequencies across environmental gradients. Such clines are thought to result from selection favouring local adaptation; however, empirical tests are scarce. The seaweed fly Coelopa frigida has an α/β inversion polymorphism, and previous work demonstrated that the α inversion freq
Learning in educational games is often associated with some form of competition. We investigated how students responded to winning or losing in an educational math game, with respect to playing with or without a Teachable Agent (TA). Students could choose between game modes in which the TA took a more passive or active role, or let the TA play a game entirely on its own. Based on the data logs fro
Environmental factors and genetic incompatibilities between parents have been suggested as important determinants for embryonic mortality and survival. The genetic set-up of the immune system, specifically the highly polymorphic major histocompatibility complex (MHC) may also influence individual resistance to infections. MHC proteins are important for an appropriate adaptive immune response and e
This thesis explores the external debt situation of developing countries and donor responses in terms of aid composition and debt relief. Primarily, these issues are important for future debt sustainability and therefore for creating beneficial conditions for accelerating growth and reducing poverty. With a focus on domestic factors (e.g. regime type) and exogenous shocks (e.g. terms of trade vol
Hypoxia is a hallmark of solid tumors, which may offer opportunities for targeted therapies of cancer; however, the mechanisms that link hypoxia to malignant transformation and tumor progression are not fully understood. Here, we show that up-regulation of the polyamine system promotes cancer cell survival during hypoxic stress. Hypoxia was found to induce polyamine transport and the key enzyme of
Intralocus sexual conflict (ISC) occurs when males and females have different adaptive peaks but are constrained fromevolving sexual dimorphism because of shared genes. Implications of this conflict on evolutionary dynamics in wild populations have not been investigated in detail. In comprehensive analyses of selection, heritability, and genetic correlations, we found evidence for an ISC over wing
A total of 308,036 women were selected from the European Prospective Investigation into Cancer and Nutrition (EPIC) study to evaluate the association between tobacco smoking and the risk of cervical intraepithelial neoplasia of grade 3 (CIN3)/carcinoma in situ (CIS) and invasive cervical cancer (ICC). At baseline, participants completed a questionnaire and provided blood samples. During a mean fol
On the basis of an article recently authored by the Swedish Minister for Public Administration, the main purpose of this thesis is to examine whether contracting authorities are allowed to refer to ‘Swedish’ standards of animal welfare (whether explicitly or not) when purchasing foodstuffs, without infringing the EU rules on free movement. In making this assessment, the thesis identifies three rec
Models of physical systems are often expressed as a system of mathematical expressions derived from first principles. However some of the relationships present in a model are more conveniently expressed as a table, i.e. for certain values of independent variables the values of dependent variables are known. This imposes a limitation on the optimization software to be used, since optimization softw
The Swedish government started its initiative for electronic services (e-services) in 2005 to create the infrastructure for information management, optimize the government, and potentially save tax money. The technological paradigm Service-Oriented Architecture (SOA) was adopted to facilitate the Swedish government's initiative. The purpose of SOA is to increase efficiency for developing e-ser
Due to a globalized market place, risk management has grown in importance and become a central part of firms’ corporate strategies. The incentives for engaging in risk reducing activities revolve around reduced agency costs and exploitation of financial advantages. According to the precautionary motive for holding cash, firms must ensure stable and secure access to capital for future investments.
The objective was to clarify whether and how it is possible to detect, track and identify with an EO/IR (electro optical/infrared) sensor. Moreover, the sight of robotic system 90 was tested in order to clarify the possibilities of using it as a sensor. The sight has a field of view of 3x4° with the TV camera and 4x6° with the IRV camera. Therefore, the project focused on a moving sensor, in order
I flera sociologiska teorier möter man en människa fångad av förtryckande strukturer utan vidare utrymme för motmakt, i ett Europa präglat av framväxande fascism och nationalism. I den här studien för jag in ett posthumanistiskt perspektiv, hämtat från Gilles Deleuze filosofi och Rosi Braidottis sociala teorier, för att undersöka människans möjligheter att göra politiskt motstånd genom utomparlameIn several sociological theories you are confronted with an individual trapped in oppressive structures without much space for counter-power, in a european context with emerging fascism and nationalism. With this study I introduce a post-humanistic perspective, inspired of Gilles Deleuze's philosophy and Rosi Braidottis social theories, to explore the possibilities for people to do political r
Höjningar och sänkningar av den globala havsnivån under pleistocen och holocen har framför allt styrts av glacio-isostatiska och glacio-eustatiska faktorer, direkt kopplade till de cykliska ökningarna respektive minskningarna av Jordens istäcken. Förutom de dominerande glacio-isostatiska och glacio-eustatiska faktorerna har flera andra komponenter påverkat havsnivån, vilket komplicerar de regionalRise and fall of the global sea level during Pleistocene and Holocene are mainly caused by glacio-isostatic and glacio-eustatic factors directly linked to the cyclic increase and decrease of the Earth’s ice sheets. Apart from the dominating glacio-isostatic and glacio-eustatic factors, several other components have influenced the global sea level, which complicates the regional sea level curves of
Mönsterseparation är en neural mekanism ansvarig för att skapa specifika, ickeöverlappande, minnesspår för stimuli som påminner om varandra. Trots denna mekanism, händer det att minnen överlappar och detta skapar ofta interferens i samband med att vi försöker plocka fram ett specifikt minne. För att reducera interferens vid framplockning aktiveras en annan mekanism, nämligen inhibition av relateraPattern separation is a neural mechanism for creating distinct, non-overlapping, memory traces for similar inputs. Despite this, memories may overlap, and this often produces interference during retrieval of a particular target memory. To reduce interference during selective retrieval another mechanism comes into play, namely inhibition of related, competing memories. This inhibition is believed t
The aim of this master’s thesis is to explore the interplay of commitment and empty labour in two widely different organisations. Empty labour can be described as when you are doing anything else than your official working tasks. Commitment on the other hand is how and in what way you feel obligated to the organisation, your boss, your colleagues’ etcetera. Depending on several factors such as col
