TCP (Transmission Control Protocol) is a transport protocol designed for the wired Internet. In wireless networks packet losses occur more frequently due to the unreliability of the physical link. The main problem is that TCP treats all losses as congestion, which leads to a lower throughput. Ad hoc networks are multihop wireless networks of mobile nodes, where each node can allow other packets to pass through it. Topology changes often occur and may lead to packet losses and delays, which TCP misinterprets as congestion.

This essay in economic geography describes what intra-firm trade as a concept is and different ways to determine in which cases trade is to be labeled as intra-firm trade (IFT) or not. The method used by the author is most easily described as descriptive. This method was chosen in order to test if existing theories; classic and neoclassic economics, new trade theory and international business studies, are capable to explain the phenomena of IFT. The theories are tested trough primary and secondary literature but also trough reasoning by the author.The conclusion is that the most reasonable way to determine whether trade occurs intra-firm or not, is to decide upon a 5-% rule where it when one part owns 5-% of the voting strength in the other company is to be considered intra-firm trade. This is a conclusion based on several reasons; the strongest one being that a common view on IFT could boost comparative studies as the U.S already collects data based on the 5-% rule.Classic and neoclassic economics are incapable of explaining IFT as aprerequisite for these theories is that markets are perfect.

A dilemma often met by entrepreneurs is whether or not to share information about their business ideas in order to increase the probability for success. The reason for sharing information is presumed to be an increased ability to develop the business idea, whereas the reason for maintaining secrecy would be to protect the idea from being stolen. Common as this dilemma is in practice, it is not very well covered in the entrepreneurial theories. The purpose of this thesis is to elaborate the theories in this subject by investigating an entrepreneurial case. The case shows that one possible solution to the dilemma is a situation-based information sharing.

This is a qualitative study about child poverty within the school environment. The purpose is to examine how financial resources can affect the social standings of teenagers and how that affects them in school; how the school system view and work with child poverty as well as how they act within the legal framework that requires the school to be free of charge. This was done through analyzing earlier research and conducting five interviews with personnel at three schools for children ages 13-15. Our results show that social standing can be affected by a lack of financial resources, partially due to not having certain mobile phones or brand clothing, partially because they cannot afford to join in on social activities. Furthermore, teenagers view child poverty as shameful and a risk factor for social exclusion.
