The use of insecure networks -such as the Internet- to send and receive information has made the need for preventing unauthorised people reading it yet more important. One of the easiest way to do this is through public key cryptography. However, the problem with this solution is how to tie a specific public key to a certain subject. This is solved by letting a trusted third party issue a certificate that holds, as a minimum, the name of the subject and the subject's public key along with the issuer's digital signature on the information. The rules we make for issuing, revoking and verifying of certificates and the entities that are being used to do so are called PKI - Public Key Infrastructure.

The Psychology Driving and Barriers to Skunk Work Projects (referred to throughout this thesis as the paper) represents a study predominantly on Tetra Pak from a selective perspective, the innovators. Innovators both past&present whose initiatives contribute to the well being of Tetra Pak as well as one from Ericsson were consulted. As with individuals, organizations possess definable characters that are influenced by the various stages of their life cycle. Theories of corporate life cycle phases and organizational character analysis were therefore employed to identify and explain organizational barriers to skunk work leaders&managers. Predicated on the Organizational Character Index survey developed by William Bridges PhD (himself a recognized leader in the field of transition management) and administered to sixty-one managers within a Tetra Pak business unit established the benchmark.

The quality of a design can improve essentially through a participatory designprocess. Initially, The Mulberry School project was supposed to be finished in two months but the involvement of artist Scott G Burnham extended the work and brought a new dimension into the project. In the beginning, Scott and I both worked on the project unaware of each other. I was appointed by the architect to design the external areas of the school and based on a site survey and analysis of the factors infl uencing the site I created a design proposal with the concept form and function. At the same time Scott performed a series of workshops initiated by the school. The purpose and goal was to include the students in the redevelopment of the school and to produce a design based on the thoughts and wishes of the students.

The sandy beaches of Vänern are threatened by overgrowth and thereby the biodiversity is at high risk to decline. This study is based on an inventory of vegetation of overgrowth character and mosses. The frequency and spread of mosses is perceived as an indication of initial or present overgrowth. External factors that have been taken into consideration are wind-, wave- and ice erosion, the slope of the beach, wear and grade of exposure. The purpose of the investigation is to control the beaches grade of overgrowth and find out which external factor is of most importance for the maintenance of the biotope. The results show that the beaches environment is affected by the slope of the beach, grade of exposure, size, wear and overgrowth.

The subject of this master thesis is co-operation between archives, libraries and museums. The purpose is twofold: 1 To map out activities within the area to get an overall picture. The mapping is done by studies of documents and consists of international outlooks and an overview of national and regional projects and reports; 2 To investigate how leaders of the respective institutions within the various regions of Sweden apprehend co-operation between the three sectors. The empirical study is accomplished by inquiries and is mainly qualitative. An intermediate purpose of this essay is to try using grounded theory to treat and analyse the gathered material.

This essay investigates how the author Oline Stig creates identities for her main characters in three short stories; Midsommar, Polly Maggoo and Den längsta dagen from the collection Den andra himlen (2007).My investigation is based on concepts chosen from psychology and narratology: First, Jonas Stier?s definition of human identity.
