The emphasize of this study is to evaluate security issues for home users having a personal computer connected to the Internet. It focus on the usage of advantages and disadvantages when using a firewall while connected to the Internet. The hypothesis is that it gives a better protection to install and use a firewall compared not to do so, due to security flaws in the operating system. The prediction was tested on a home user's personal computer. The testwork was divided into two major tests, each of them performed with, respectively without, a firewall. These major tests were divided into five smaller semi­ tests. The first semi­test without a firewall suffered from a virus or worm attack resulting in loss of data and log files.

When the Swedish National Agency for Education received the assignment to develop new purposes and national tests to the third grade students, debate took a bounce.

Inlösen eller extrautdelning?: En studie av sambandet mellan valet av kapitalåterföringsmetod och värdeskapande för aktieägarna

This thesis studies the stock price reaction around 68 announcements of special dividends and share redemptions on the Swedish stock market between the years of 2003 and 2007. We show that for the Swedish private investor, the tax effect of a share redemption is lower than that of a special dividend. Moreover, a share redemption could be interpreted as a signal of undervaluation. These two factors lead us to assume that the stock market would react more positively in connection to the announcement of a share redemption. We test this hypothesis through an analysis of the risk-adjusted abnormal return for the observations in the sample.
