Ants and termites in small-scale plantain farms in Uganda : a comparison between agroforestry and non-agroforestry farms

This study was conducted in Kkingo district, west of Masaka, Uganda. It compared soil macrofauna abundance in non-agroforestry farms with that of agroforestry farms. The agroforestry farms had participated in the Vi Agroforestry´s program between 1995 and 2006, and continued on their own after 2006, when Vi Agroforestry left the area. The soil macrofauna is important for soil structure and processes that are contributing to soil organ-ic matter decomposition and nutrient mineralization. They are also predators of potential pests.

Brasilien - ett modernt men religiöst land : En fallstudie av Brasilien utifrån Pippa Norris och Ronald Ingleharts teori om sekularisering och religiositet

The aim of this study is to examine the religious landscape of Brazil, and based on the theory of secularization by Pippa Norris and Ronald Inglehart to explain why Brazilians are religious and not secular. The study is a secondary analysis that uses existing statistics to examine different units of analysis of Brazil?s religious landscape, economics and equality, etc. Based on their theory I find that Brazil is still religious due to the lack of security in the country. Brazil is insecure in terms of measures of socioeconomic equality, stable politics without corruption, and physical safety of the citizens in Brazil.

Adoptionen av Affärsdriven SOA

Uppsatsen ämnar ge en indikation på huruvida affärsdriven SOA har adopterats i organisationer vilka har utfört eller planerat att utföra ett SOA-initiativ. Genom att karakterisera begreppet SOA via den litterära grund uppsatsen vilar på, har vi kunnat identifiera teman utifrån vilka vi utformat en intervjuguide i syfte att utföra en intervjuundersökning, i form av semistrukturerade intervjuer. Det empiriska materialet transkriberades och analyserades. Via meningskoncentration kunde vi sedan presentera informanternas syn på ovanstående syfte samt relatera detta till litteraturgenomgången. Detta resonemang blev till en diskussion för att därifrån nå ett resultat och således kunna ge ett forskningsbidrag.

Interorganisatoriska interaktioner inom Inkubatorer : En studie om kunskapsutbyte och inkubatorsystem

BackgroundIncubators are important facilities for economic growth in society. The main purpose of incubators is to accelerate knowledge intensive firms onto their market by both providing resources and an entrepreneurial environment.Problem Companies within incubators are encouraged to share knowledge and experience with each other with the goal to stimulate development and invention of new technology. This exchange involves interaction on an inter-personal and inter-organizational level. Incubators need to create an open and transparent environment in order to enable this exchange on both levels.Purpose The purpose of this study is to enhance the understanding of how knowledge and experience exchange occurs within the context of incubator systems. By understanding how incubators can capture knowledge and learn from the incubator process, this study can contribute by insights of how the incubator process can be further improved.Method This bachelor thesis is written from an abductive approach and is based on a qualitative case study of Ideon Innovation in Lund.

Positive human to cattle interactions and the possibilities to increase animal welfare, economy and safety for farmers

Cattle production systems are changing to bigger intensified systems with larger numbers of animals per farm and more free range systems while at the same time employing fewer people. Aversive handling has been known to affect cattle production negatively for many years, but lately scientists have started to focus more on what positive effects gentle handling and positive human-cattle interactions may have on beef and dairy production. Fear can cause high stress in production animals and this can contribute to not only reduced production within beef and dairy cattle, but also increased risks for accidents and decreased animal welfare. Therefore, by reducing the fear cattle experience of humans, it could be possible to increase production, decrease accidents and increase the welfare of the animals. Reducing the animals fear and stress can be done by simple means, such as walking and talking calmly around the cattle, associating humans to positive feelings (such as feed) and stroking the cattle?s body regions associated with social grooming.

"Att stå på en hundsläde är ingen motion.": Hur motiveras polarhundsägare till fysisk aktivitet?

Tidigare forskning har visat att hundägare är mer fysiskt aktiva än de som inte äger hund. Deras motivation att vara mer fysiskt aktiv bygger på den sociala interaktionen med hund eller träningskompisar som hundträning/rastning medför. Med hjälp av Self-Determination Theory (SDT) undersöktes vad som motiverar just hundspannsförare att träna själv och hunden. Åtta personer som ägde hund och körde hundspann intervjuades. Frågorna kretsade kring tiden före och efter det att de ägde hund.

Hur fungerar en glaselektrod?

To understand the glass electrode needs knowledge from more than one level. The construction ofthe glass electrode is one part, an other is the composition and structure of glass. The Nernstequation have an important role, but also the sources of errors in the analysis and the calibration ofthe glass electrode. Focus for this article is how the glass electrode really works and how Gibbs freeenergy made the potential dependent of the concentration of H+and gives the logarithm to thefunction. Nikolskii's ion exchange theory starts to explain the question about how the potentialcreates and Baucke's dissociation mechanism made it more explicit.

Renskötselrätten : som rättslig konstruktion

This master thesis concerns the relation between law and the theory of the conceptual metaphor which has developed within cognitive linguistics. Although its main focus is abstract thinking, it also covers a wide range of aspects within cognitive linguistics, such as the prototype theory and radial categories. In order to address this relation, three questions will be dealt with. Firstly, does the theory of the conceptual metaphor have relevance to interpretation of legal rules and contracts? Secondly, can the same theory explain why a legal rule or a contractual term has been interpreted outside of its most given area of application? Thirdly, when an interpretation is not predictable from a legal viewpoint, can such an explanation answer to that fact? Answering the first question will require a descriptive analysis of the conceptual metaphor and cognitive linguistics.

Demokrati och den retoriska kunskapens potential : Ett retoriskt perspektiv på deliberation

This study investigates the potential of a rhetorical theory of knowledge to expand beyond its own domain and into political theory, specifically theories of deliberative democracy. Despite the increasing interest in communication in democratic theory in the last decades, the majority of theorists have not turned their interest towards rhetorical science. On the contrary, theorists often regard rhetoric as dangerous and incompatible with the deliberative ideal of reason. The aim of this study is therefore to defend rhetorical science by investigating how the rhetorical theory of knowledge ? as it is presented by Chaïm Perelman and Oldbrecht Tyteca, and further developed by Mats Rosengren and Maria Wolrath Söderberg ? can contribute to the understanding of deliberative democracy.

Utformning och evaluering av kommunikationsmodell för analys av e-postbaserad kommunikation

I denna designstudie överges dagens syn på e-postmedierad kommunikation som en linjär process. Bilden som linjära modeller ger av verkligheten är alldeles för generaliserad. Kommunikationsmodeller idag bortser från eller lägger minimal vikt på aspekter som är av betydande roll för hela kommunikationsprocessen. Syftet med denna designstudie är att utforma och evaluera en kommunikationsmodell som ska ligga till grund för analysering av e-postkommunikation. Modellen bygger på existerande teorier från kommunikationsvetenskapen och har modifierats med fenomen och aspekter som gör att den på ett realistiskt sätt speglar en verklig kommunikationsprocess.

Högläsning i förskoleklass : En studie om fem pedagogers arbete med högläsning

The purpose of this paper is to explore how masculinity and femininity are constructed in the magazine Veckorevyn, through a critical discourse analysis of 18 articles from six issues in 2011. This is done by using a variety of theories and previous research results, which is gender theory, the theory of late-modern society and media theory. The analysis shows that Veckorevyn depicts virility and feminine differently. Furthermore, pointing the results from the analysis that a change of manhood and womanhood takes place in the social practice. The selection of articles from the magazine also shows that Veckorevyn seems to promote gender equality. .

Regionala obalanser och matchningseffektivitet i Sverige 1983-2004

Denna uppsats analyserar matchningseffektiviteten mellan lediga jobb (vakanser) och arbetslösa. Det faktum att den svenska Beveridgekurvan skiftat utåt under 1990-talet är en indikation på att de arbetslösa inte lika effektivt ?matchas? ihop med de lediga jobb som skapas. I uppsatsen identifieras två faktorer som påverkar matchningseffektiviteten; sökbeteendet hos arbetsgivarna och de arbetslösa, samt regionala obalanser mellan utbud och efterfrågan på arbetskraft. Sammanfattningsvis kan sägas att båda faktorerna tycks bidragit till sämre matchningseffektivitet under 1990-talet..

Energioptimering : Resteffektkylning av mellanlager för använt kärnbränsle (CLAB) Oskarshamn

This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.
