One of the main challenges in evolutionary ecology is to identify the factors and agents that drive diversification. Two of the most diverse groups of organisms on earth are plants and insects, and evidence strongly suggests that the diversification of both groups is driven by the interactions between them. One fruitful way for understanding how these interactions evolve and diversify is to identi
Syftet med examensarbetet är att studera ledarskapet och ledarens roll i förändringsarbetet mot ett klimatneutralt byggande. I studien utreds vilka faktorer som driver förändringsarbetet mot ett klimatneutralt byggande och hur miljöarbetet kan bli mer attraktivt för anställda i svenska byggföretag. Studien har utförts på ett fallföretag och ett av deras projekt i produktionsfasen. En kvalitativ mThe purpose of this master thesis is to study the leadership and the roll of the leader during a change in the process towards a climate neutral construction process. The study is aiming to find factors which affects the change process towards a climate neutral construction process as well as how the environmental work can become more attractive in projects. The study has been carried out as a ca
In 2009 the Swedish parliament decides to discontinue the conscript service, and in 2010 it was replaced by a system based on employed personnel. The purpose of this study is to analyze the factors leading up to the decision to abandon conscript service. This question is interesting to study because the conscript service was reinstated only seven years later due to a worsen security situation and
This thesis studies the distribution of accessibility by public transport to retail concentrations and public hospitals in Athens, using spatial autocorrelation analysis based on Local Indicators of Spatial Autocorrelation (LISA) method and Geographically Weighted Regression (GWR). For this reason, the study area was divided in a 300x300 meter square grid of points representing the location point
The ever-increasing need for higher performance and more complex functionality pushes the electronics industry to find a faster and more efficient way to test and debug an Integrated Circuit (IC). Currently, the IEEE Std. 1149.1, known as Joint Test Action Group (JTAG) is considered as state of the art by the industry. JTAG is used to perform debugging and testing through Test Access Port (TAP). H
Within the last twenty years, the Swedish military has been drastically reduced in size and capability. The conscription service was discontinued which made retaining personnel difficult. The service was reinstated nine years later due to the geopolitical instability around Sweden and the national goal to double personnel by 2035. Consequently, the military must focus on retaining trained personne
In order for civilian shipping and aviation to be able to operate within Swedish areas of responsibility, an absolute prerequisite is that the state must maintain a well-functioning sea and air rescue service. This requires constant, thorough surface coverage, year round and around the clock with qualified helicopter resources. Until 2002 Swedish national needs, both military and civilian, were ma
Statistical modelling of certain phenomenon to extract patterns is a common theme in data analysis. Applying this precise theme to call center data is riddled with many practical con- cerns and has lead to development of new concepts and theories in stochastic processes. In this thesis we intend to study specic call center dataset with the objective of studying patterns in call arrivals over a per
Today, Sweden is well-known as a nation with a strong voice for non-proliferation and disarmament. This has not always been the case though, during the 1950´s the country was on its way to develop nuclear weapons of its own. This paper seeks to examine how this shift of direction happened during the 1960´s, and how it has affected Swedish security and defence policy as of today. This paper aims t
The purpose of this paper is to compare the posture and operations of Russian nuclear submarines compared to their Soviet predecessors, in the context of nuclear weapons. By conducting a case study comparing the Soviet and Russian nuclear doctrines and their application, limited to the submarine part of the Nuclear triad, and using the Organizational logics model as the method and Waltz’s 3rd imag
In January 2017 the Swedish Prime minister announced at a conference in Sälen that for the first time in history Sweden now had a National Security Strategy and it was now to be implemented. In Sweden, ministers in the Cabinet are not allowed by the constitution to directly influence the work of Sweden’s governmental authorities. The institutions of the government are independent in the execution
The abduction, or arrest as it´s referred to in Russia, of Eston Kohver on the border between Estonia and Russia in September 2014 caused many nations in the western world to condemn the practices of both the Russian counter-intelligence directorate and the Russian justice system. The aim of this thesis is to try to uncover why Russia acted as it did by applying Graham Allison and Philip Zelikows
Ever since the end of the Cold War, there has been a differentiated view of the need for a national defense between Sweden and Finland. During the 2000s, Finland has had a strong national defense in relation to its spruce counttries, while Sweden gradually phased out its national defense capabilities. The purpose of this case study is to identify the reason why the two countries have distinguished
This study thesis Swedish national defence cooperation during the time of the Cold War until today within the spectrum of foreign and security policy. The question to be answered are how Sweden has interact with affecting circumstances regarding national security when deciding type of defence cooperation, and how has Swedish defense cooperation evolved into what it is today. The consequences dur
In 2009, Bitcoin was introduced to the world. Today, ten years later, there are still gaps in the research of how to model the cryptocurrency. In this thesis, the capacities of different volatility models to capture the high volatility of Bitcoin returns are investigated. The models used are GARCH-type models: GARCH(1,1), IGARCH(1,1) and GJR-GARCH(1,1). Jumps, or outliers, are also detected and fi
MRI can be used as an non-invasive method to map the brain. By correlating diffusion with relaxation it is possible to separate different tissue kinds such as white matter, grey matter and free water. In this work we look at how to bin the data to best separate the tissues. By modifying the bin limits in Diso, Dperp / Dparallel, \DDelta and R2 it will be shown that there is not a single optimal
Female-limited colour polymorphisms provide interesting examples of intraspecific genetic diversity but, in most polymorphic taxa, we know little about the macroevolutionary origin and subsequent history of polymorphism during diversification. The damselfly genus Ischnura includes many species with multiple, heritable female colour morphs. The evolutionary origin of polymorphism in this clade is u
When two materials with different lattice constants are grown together, this generates stress between them, and therefore strain. This strain causes them to have different thermal and electrical properties, and this is especially important on the nanoscale where changes have large impacts. This project is intended to see if COMSOL can be used as a tool to model how materials respond to lattice mi
The current textile industry is among the most polluting industries and actions should be taken to decrease these negative impacts. One issue that should be addressed is the increasing amount of textile waste. Post-consumer textiles are often incinerated or downcycled due to many factors. In order to move towards a circular clothing system, businesses and policy makers play a major role. The purpo
