The purpose of this study is to examine whether an acquiring firm that operates as a contractor within the defence sector can expect to generate shareholder value from a merger and acquisition with a fellow defence sector competitor. Having selected thirty acquiring defence firms an event study utilizing the market model is performed to obtain the abnormal returns generated from a merger and acqui
The debt equity bias refers to the discrimination between debt and equity finance. This discrimination is problematic since it distorts companies’ decisions and increases systemic risk. The European Commission has recommended Sweden to eliminate or reduce the bias and the Swedish Ministry of Finance has gathered a committee to investigate possible solutions. Sørensen (2010) suggested that Sweden w
Denna uppsats syftar till att undersöka hur de två faktorerna självförtroende och inre motivation skiljer sig åt mellan personer som har kommit olika långt i riktning mot ett fysiskt aktivt liv. 144 försökspersoner besvarade 19 frågor i en enkätstudie. Deras svar angående motionsvanor och attityd gentemot fysisk aktivitet placerade dem i olika faser i den transteoretiska modellen. Därefter jämförd
Studien undersökte grundskolelärares inställning till att bli utvärderade av sina elever. Metoden var kvantitativ och en enkät utformades av författarna för att förstå lärarnas inställning. Svar från 55 grundskolelärare analyserades och presenterades i studien. Resultatet visade att grundskolelärare inte anser att elevutvärderingar kan bidra till att förbättra undervisningen. Lärarna trodde att deThe study investigated grade school teachers’ attitudes about pupil evaluation of teaching. The method used was quantitative and a questionnaire was developed to capture the teachers’ attitudes. A sample of 55 grade school teachers was analyzed and presented in this study. The results indicated that grade school teachers do not find pupil evaluations helpful in improving their teaching. The teache
As the representation of people’s identity, dress reveals people’s characteristics, social status and most importantly, how people want to be “looked like”. The same theory can be applied to film costume, which is not only a purely visual spectacle but also an important element to sustain the entire film. Film costume on one hand helps to form the concepts and images of different characters and th
Prefetching is a well known concept for CPUs but for GPUs it is fairly unexplored. The memory management of a GPU plays a crucial role in its performance, and cache prefetching has the potential to lower the overall latency. This thesis compares different types of prefetching methods for GPUs and remaking some CPU prefetchers to fit the GPU architecture. All these prefetchers were then put inside
Sub Saharan African (SSA) countries are facing severe economic challenges such as high trade costs, poor trade performance and low growth levels. As a result development assistance is needed to overcome these difficulties. SSA countries receive the highest share of Aid for Trade (AfT) and therefore it is important to assess the effects of AfT. This study investigates the trade effect of AfT on tra
Utredningshemmet in Hässleholm, Sweden, is a special residential home for acute management and investigative evaluation of juvenile delinquents. Utredningshemmet has, since 1991, used an investigative model, which is based on systems theory. The investigative work is done in close co-operation with social workers, youths and their parents. This study takes into account the youths, who have had a
To create an environmentally friendly road transport system is one of the main policy goals of the Swedish National Road Administration (Vägverket). In order to achieve this goal Environmental Impact Assessment (EIA) has been introduced at all levels of road planning process at Vägverket. The role of EIA is to provide decision-makers with information about the possible consequences of a planned fa
Using primary research from majority-Western respondents in conjunction with an array of multi-disciplinary secondary literature, this thesis acts as a response to claims of the overwhelming existence of ‘placelessness’ in our modernised and globalised world. Instead, it suggests that place attachment is alive and well in the West. Furthermore this thesis suggests that place attachment can be show
Background: Stingless bees are vital pollinators and honey producers in the tropics. Research on stingless bees is generally underrepresented compared to the western honeybees, and while stingless bee studies from some regions are reported, there is a particular lack of reports on the species endemic to Sub-Saharan Africa. Since conventional entomological methods such as mark-recapture and radar h
Insects rely on path integration (vector-based navigation) and landmark guidance to perform sophisticated navigational feats, rivaling those seen in mammals. Bees in particular exhibit complex navigation behaviors including creating optimal routes and novel shortcuts between locations, an ability historically indicative of the presence of a cognitive map. A mammalian cognitive map has been widely
Atmospheric measurements show that emissions of hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons are now the primary drivers of the positive growth in synthetic greenhouse gas (SGHG) radiative forcing. We infer recent SGHG emissions and examine the impact of future emissions scenarios, with a particular focus on proposals to reduce HFC use under the Montreal Protocol. If these proposals are
Compared to intensive research on km-sized meteorite impact craters, fewer studies focus on smaller craters. The small craters are often hard or impossible to recognize using “classical” criteria like the presence of shatter cones, shocked quartz, and geochemical indicators. Therefore, a long list of candidate structures awaiting approval/disapproval of their origin has been formed over the last d
Globally, the lifespan of populations increases but the healthspan is lagging behind. Previous research showed that survival into extreme ages (longevity) clusters in families as illustrated by the increasing lifespan of study participants with each additional long-lived family member. Here we investigate whether the healthspan in such families follows a similar quantitative pattern using three-ge
A new aromatic pair, 2-hydroxy-6-methoxybenzamide/1-methylpyrrole at the terminal position of hairpin polyamides has been designed for distinguishing T·A from A·T base pairs and both from G·C/C·G in the minor groove of DNA. Four eight-ring hairpin polyamides with benzamide (Bz), 2-hydroxybenzamide (Hb-1), 2-hydroxy-6-methylbenzamide (Hb-2), and 2-hydroxy-6-methoxybenzamide (Hb-3) at the N-terminal
