Jordlöparfaunan i bestånd av contortatall (Pinus contorta) och svensk tall (P. sylvestris) 1987 och 2010

In the 1970´s the North American lodgepole pine (Pinus contorta) was introduced to Sweden in large scale. The lodgepole pine affects its new environment different from Scots pine (P. sylvestris), leading to a change in biological diversity. Forestry today affects the ground beetle fauna (Carabidae). Habitat specialists associated with older forests are first affected. When the canopy closes again after a clear-cutting species that prefer open habitats reduces and those who prefer mature/closed forests increase. In this study we compare differences in diversity and community structure of ground beetles in stands of lodgepole pine and Scots pine.

Sand pits as habitat for ground beetles (Carabidae) : does the area affect species number and composition?

Sand pits are a valuable habitat which can hold many sand living species including several endangered ones. As many sand habitats with exposed sand are declining, sand pits have a potential as a substitute habitat. This study was conducted to see what effect the area of a sand pit has on species number and composition of ground beetles (Coleoptera: Carabidae). Also, the effects of other environmental variables were tested, for example the proportion open sand, vegetation cover, sun exposure and tree cover. The study was conducted in the county of Uppsala in 2008 and included 13 sand pits with areas between 200 and 180,000 m2.

Arbetsplatsträffars effektivitet och utvecklingsnivåer : En observationsstudie inom en kommunal grundskola

The study aimed to highlight workplace meetings´ benefit and what level of development. The study was done at a school in Lidköping and included two qualitative observations. Most of the groups´ members were women; one man was included in each group, and there was a mixed age structure of the meeting participants. The collection of data was then paired with the scientific literature and scientific articles. .. Our results demonstrate that group 1 spend 59% of the time on information and 41% of communication.

Social Construction of Crisis: The Constructed Realities of SAS Ground Service Employees Regarding the Preparatory Period of Strategy 2011 Organizational Development Program.

The thesis explores an ongoing dialectical process between different levels of employees including top management to workers of Scandinavian Airline Service (SAS) regarding a new change program and to find out the possible social construction among them. In particular, it searches for the constructed reality of SAS ground service employees at Malmö Airport with regard to the preparatory stage of SAS Strategy 2011. A possible ambiguity in dialectical process is explored as it relates to an organization?s ability to effectively influence the understanding and identity of its employees through discourse.

1000 volt och jag ville vara med - en litteraturstudie om anhörigas eventuella närvaro under återupplivningsförsök

The aim of this study is to investigate attitudes among relatives and Emergency Department staff, concerning relatives possible presence during resuscitation. Seven scientific articles revises in the studys method. The articles have been searched for in CINAHL, Elin and PubMed. Articles have been analysed using Polit, Beck and Hungler (2001) instructions to evaluate scientific quality. The findings of this study show there it seems no longer appropriate routinely excluding relatives from family presence during resuscitation.

Är objektiva moraliska värden möjliga utan Gud? : en teoriprövning av Moralens Landskap

What drove me to write this paper is the will to  examine if there is a philosophically and scientifically viable  alternative foundation for an objective morality other than what we like to refer to as "God". The  American philosopher and neuroscientist Sam Harris presents in his book The Moral Landscape a thesis for an objective morality based on science in which he states that  science can determine human values. The purpose of this paper is to perform a theoretical trial of The Moral Landscape, examining Harris' thesis and it's relations to the philosophical obstacles that stands in its way, these being mainly the famous philosophical principle "Hume's Law" and G.E. Moore's "Naturalistic Fallacy and Open Question Argument" and thus will serve as my main theoretical foundation. The results of my study was not conclusive since Harris in fact doesn't succeed in bridging the gap between facts and values on a Scientific ground.

Bibliotekariebilder i dagens platsannonser. En diskursanalys.

The aim of this Masters thesis is to examine the librarian discourses that can be identified in the job advertisements of today, to examine how the discourses differ and also how these discourses might influence the librarian profession and its status. The method of investigation is a qualitative analysis of printed sources, using Ernesto Laclaus and Chantal Mouffes discourse theory as well as the theory of professions as a theoretical base. The thesis shows that two discourses can be identified in job advertisements for 2004, one public librarian discourse and one scientific librarian discourse. The major difference between the two discourses are work tasks where the public librarian discourse very often contains areas of responsibility and development work, whereas the scientific librarian discourse often contains administrative work tasks. Other differences include a great demand for driving licences and an interest in children and youth in the public librarian discourse, something which is not asked for at all in the scientific librarian discourse where there is a great demand for knowledge of languages instead.

Framtidens begravningsplatser : en historisk tillbakablick, dagssituationen och visioner för framtidens gestaltningsuttryck

The purpose of this article is partly to find out how the burial grounds are used today and the needs of its visitors, but also to develop the character and expression of future burial grounds. My suggestions focus on burial grounds without religious attributes; something that, according to the burial law (Begravningslagen, 1990:1144), the manager of the burial ground is ordered to obey. In my design I aim to fulfill any requests regarding the place of burial that have been raised during my study. I have chosen the history of burial grounds as my starting point and will subsequently discuss their significance in today's society. I describe what distinguishes the burial ground throughout history from medieval times and onwards. Tradition and religion are closely linked regarding burial rituals.

Use of dogs as odour detectors : a review of the scientific literture

A lot of various substances can be detected by dogs, as oestrous in cows, endangered species or non-biological substances like accelerants, narcotics, explosives, mines and pollutions and biological substances like identity (suspects), cancer (breast, lung, colorectal and bladder cancer), human remains (cadaver), bacteria and mould in buildings. The dogs are trained using non-scientific methods and not much research in detection training exists. This is a review of different types of dog detection, with focus on new research..

Vetenskapsteoretiska och metodologiska perspektiv på tidsgeografiska visualiseringsmodeller. -En fallstudie i samhällsvetenskaplig visualisering

In the history of scientific visualization techniques there is a lack of social science practices and methodologies. The advent of modern computer graphics brought the use of visualizations into a whole new era, but even though the tools by which such modern visualizations are created become easier to access and use, the lack of social science researchers harvesting the benefits of such tools still remain. This ease of use, increase in power and accessibility plus the ever growing need within the natural sciences to augment the human senses has further complicated the relationship between scientific methodologies, validity, reliability and the use of visualization techniques. This relationship must be explored, demystified and understood in order to fully grasp the impact of visualization practices when incorporated into any given scientific method. Within the social sciences there is one example of a tradition that has since its conception carried within it a graphical notion and a visualization practice.

Att utvärdera vetenskapliga tidskrifter: En kritisk analys av Journal Impact Factor: en metod inom citeringsanalys.

The purpose of this Masters thesis is to make a critical analysis of Journal Impact Factor JIF. JIF is today the most widespread quantitative measure for evaluating scientific journals. Although it is internationally used and is considered authoritarian many problems have been observed. This has led to that the validity of JIF has been questioned. To identify JIFs limitations the following issues have been raised: Which are the problems with citation analysis? What criticisms have been directed towards Journal Impact Factor as a measure for evaluating scientific journals? The theoretical framework consists of theories about citation behaviour and a discussion about the characteristics of a scientific journal.

Rektorers uppfattningar av vad en skola på vetenskaplig grund och beprövad erfarenhet innebär

Den här studien utforskar genom fenomenografins arbetssätt, vad det innebär för rektorer att undervisningen vilar på vetenskaplig grund och beprövad erfarenhet samt hur rektorerna arbetar för detta på sin skola. Skollagen från 2010 har i första paragrafen inskrivet att utbildningen ska vila på vetenskaplig grund och beprövad erfarenhet.  Genom intervjuer har rektorer i gymnasieskolan svarat på vad skollagens nya skrivning innebär för dem. Rektorerna har svarat på vad det innebär för dem att undervisningen på deras skola ska vila på vetenskaplig grund och beprövad erfarenhet och hur de arbetar för att detta ska komma till stånd. En differentierad bild ges av gymnasieskolornas olika förutsättningar att anta denna utmaning. Rektorerna visar på svårigheter med att ge alla elever samma förutsättningar, då bland annat ämne och programtillhörighet ger olika möjligheter.

Stålfiberarmerad betong för platta på mark : -En kostnads- och sprickbreddsanalys

AbstractToday there is an opportunity to reinforce concrete with steel fiber reinforcement. In some cases, completely replace the conventional reinforcement. Replacing conventional mesh reinforcement with steel fiber reinforcement in slabs on ground has shown economic benefits, less crack width and less reinforcement amount.Today there are no Swedish standard for designing steel fiber reinforced concrete, what is there is different international recommendations.In this work, design methods for steel fiber concrete are used according to RILEM and Bekaer Swedish AB's software DRAPRO. For other design methods Eurokod 2 is followed.In this work, the design of slabs on ground that are not exposed by large tension strength been designed. Design of crack-reinforcement and restrictions of crack width have been conducted in three different slabs on ground.The calculations have been performed using only conventional reinforcement and only steel fiber reinforcement, and the results are then compared.The results of the theoretical analysis are summarized in tables that compare the amount of reinforcement, crack width and economic cost.This work showed that the slabs on the ground reinforced with steel fibers provide less crack width with a minor amount of reinforcement.

Räder och svensk doktrin samt reglemente för markoperationer?

NATO, USA, Storbritannien och Ryssland m.fl. använder sig av stridsuppgiften räd för markstridskrafter och erfarenheter från bl.a. Irakkriget 2003 visar att de kan få stor betydelse. Räder anses överensstämma med manöverteorin, men räder återfinns inte som stridsuppgift för svenska markstridskrafter.Denna uppsats analyserar stridsuppgiften räd för markstridskrafter, operationaliserar två indikatorer för räder och med hjälp av dessa undersöks hur räder är förenligt med FM nuvarande doktrin och Reglemente för Markoperationer (RMO).Undersökningen visar att räder inte är förenliga med nuvarande doktrin och RMO. Bl.a.

Marknadsföringsbegrepp i praktiken : En kvalitativ studie om tillämpningen av priming, upplevelserummet och relationsmarknadsföring i fallet HV71

The study is based on the pragmatic question whether one can apply the theoretical perspectives priming, experience space and relationship marketing in a practical context. The authors visualize how these concepts appear practical and what advantages and disadvantages can be discerned in the particular case of HV71. The method used is a hypothetico-deductive approach, which is not entirely conventional in the humanistic and social scientific context. Consequently, it has been proven to be particularly suitable as it could expose the theoretical perspectives for a difficult scientific test.The result of the study demonstrated that a marketer could benefit from using the theoretical perspectives when exercising the profession. It also showed that the object of study applied these perspectives.
