Bacterial contamination of eggshells in conventional cages and litter floor systems for laying hens in Jordan

In the country of Jordan, egg production is very important economically, but several bacte-ria are involved in food borne diseases transmitted from eggs or other poultry products. The most important are Salmonella spp., Campylobacter jejuni and Escherichia coli. In Jordan two different housing systems are used for hens in large scale egg production; con-ventional cages and litter floor systems. Eggs from four different farms were analysed and compared to see if a difference could be found regarding the presence of pathogenic bacte-ria on the egg surfaces between these two systems. Total number of aerobic bacteria was analysed, the presence of Salmonella spp., C.

Biblioteks- och informationsvetenskap som kunskapsområde En bibliometrisk studie.

The objective of the study is to map the cognitive structure of Library and Information Science, using a quantitative, bibliometric method. This empirical study shows how co-citation analysis combined with word-frequency analysis can be used to describe the subject content of the field. The research questions to be answered are: -Which clusters of authors can be identified? -How can these clusters be described in respect of their subject content, if the descriptors associated with the authors in the clusters are counted? The results show that the cognitive structure of Library and Information Science can be described by 13 clusters of authors, where each cluster is representing a specific aspect of the subject- domain. For the description of the subject content of the clusters, descriptors DE of the LISA database have been used..

System, stabilitet och makt - informationsdiskursen i Organizing Knowledge

TitleSystems, Stability and Power. The Discourse of Information in Organizing Knowledge.AbstractThe aim of this Master's thesis is to inquire into the consequences of an unequal distribution of power between information discourses in the field of knowledge organisation. A deconstruction of Jennifer Rowley's and John Farrows introductory textbook Organizing Knowledge from 2000 is related to the major discourses of information in LIS. Questions posed in this study are: What meaning is ascribed to information in the material studied? Which information discourses are given a dominant position? Which are excluded? and: How does this affect the construction of the library and information science student's identity, in relation to practices of knowledge organisation? The theoretical framework is provided by Ernesto Laclau's and Chantal Mouffe's theory of discourse and combined with techniques for text analysis originating from the work of Norman Fairclough.The analysis reveals a strong domination of a cognitive discourse of information that underlines the importance of information systems for the organisation of knowledge.

Informationssäkerhet i en mediekoncern : Ett penetrationstest med inriktning på datautvinning och social-engineering

Målet med denna rapport är att studera informationssäkerheten på ett företag i den svenska mediebranschen. Att upprätthålla en bra informationssäkerhet är särskilt viktigt för ett medieföretag, då de dagligen hanterar källskyddat material. För att komma över känslig information utfördes penetrationstester genom social-engineering och datautvinning. Resultaten av dessa tester visade att det var relativt enkelt för en angripare att få de anställda att ge ifrån sig lösenord till företagets interna nätverk och VPN-klienter. Datautvinningen visade även att i princip all information gick att utvinna eller återskapa från företagets datorer eftersom man inte använde någon form av kryptering.

Att sjunga en fråga. En jämförelse av tre Query-by-Humming-system och deras användare.

The aim of this study was to compare the Query-by-Humming systems Midomi, Musicline and Tunebot regarding their retrieval effectiveness. The aim was to see if there were differences between the systems but also between the user groups common users, musicians and singers. Query-by-Humming system means that the user sings a tune that the system then use to find the right melody.To compare the systems and their users, queries where collected from the different user groups and replayed for the systems. Mean Reciprocal Rank and Friedman test was used to do the comparison.The results showed that the system did not achieve equivalent and that there were no difference between the user groups. The Mean Reciprocal Rank showed that the systems had very different retrieval effectiveness, where Midomi was the system with best result and Musicline with the lowest result..

Styrreglage för hållbarhetsstyrning - En fallstudie av hur företags interna styrning aktiverar Levers of Control för att uppfylla hållbarhetskrav

The connection between management control systems for controlling sustainability and a firm's motivation for engaging in sustainability is not completely understood (Arjaliès & Mundy, 2013). The aim of this thesis is to develop a more profound understanding for management control in achieving sustainable companies. To do this, we raise the question: How and to what extent do companies use management control systems to achieve sustainability compliance Simons's Levers of Control (1995) are applied to this question in order to get a consistent and thorough insight of management control systems. Hence, a case study of ABB:s work to achieve material compliance in accordance with EU-regulation was conducted. The findings of the case study reveal that ABB uses the regulations as explicit goals and implement them in sustainability procedures.

Belöningssystem i heterogena organisationer -I teori och praktik

The purpose of this master thesis is to, with the strategies of the organization and the preferences of the co-workers in mind, explore how reward systems can be designed in heterogeneous organizations. This is done by interviewing store managers and sales personnel in a heterogeneous organization. The frame of reference deals with theoretical approaches on reward systems and is divided in the following sections, individual or group based, differentiated or not differentiated rewards systems and goals, measurements and rewards. These sections are highlighted from the following aspects, equity, implementation possibilities and finally environment. The theoretical discussion ends in the conclusion that heterogeneous organizations should have several different reward systems, but not if a restructuring process is in progress or the system becomes too costly.
