Corporate Social Responsibility (CSR) has recently become increasingly important for companies to integrate into their ongoing work. CSR is about social, environmental- and financial responsibilities. The tourism industry often involves large impacts especially on environmental and social factors, which is why CSR-work plays an important role according to previous studies. One trend that has increased among consumers in the tourism industry during recent years is to travel to the lowest possible price. It has for example become increasingly common to book airfare by budget airlines.

The fungus Gremmeniella abietina causes damage to conifers that can lead to tree death. In 1999 and 2001 the pathogen caused severe attacks in Sweden, where about 500 000 ha of pine forest were affected. Trees of all ages were attacked, but mainly forests between 30-60 years that were ready for their first commercial thinning. After recommendations from the forest agency, sanitary fellings were made to trees that had more needle loss than 85%, a total of about 50 000 ha. Economic losses have been estimated to more than one billion SEK.

Handling product returns has become a critical activity for organizations as the volume of gods flowing back through the supply chain rapidly increases. Few research studies have published specific empirical data concerning the reverse logistics practices of companies. Information technology and information support has long been recognized as a competitive weapon ? capable of enhancing company performance and achieving efficient reverse logistics. Reverse logistics is very unlike the forward, as it is more reactive and also has less visibility.

This is a study in how astronomy has been taught and is being taught in Swedish schools from 1905 to this date with an emphasis on the latest 30 years. It concerns the regulations and methodical recommendations/curricula for Swedish junior high school/Swedish Comprehensive school for the years 1905, 1933, 1955, 1958, 1962, 1969, 1980 and 1994. The matter of integrating astronomy with other subjects and different methodical approaches is also considered. The problem with textbooks written only for one subject when the teacher tries to integrate subjects is emphasised.Physics textbook analysis shows that astronomy teaching has over the years developed, from being based on observations, to become more and more theoretical. It also shows that the amount of practical exercises has been fairly constant in physics textbooks during the seventies end eighties but now in the nineties varies a lot from textbook to textbook. The amount of liberty the textbook gives the pupil in finding knowledge and answers himself in the practical parts of astronomy was at its lowest during the seventies.

The flexibility of the labour market is considered as an instrument for increasing economic growth.Therefore has the use of flexible employment, also called atypical employment, increased. The atypical employment is characterized by insecurity in comparison with a traditional permanent full- time employment. One of the most common atypical employments is the manning employment, which is insecure whether it is permanent or not. The insecurity in the industry is based on insecure income, unpredictable working hours and poor psychosocial work environment.In order to encourage a continued increase of flexibility in the labour market while the need for security for staffing employees would be satisfied was Directive 2008:104 adopted. A certain amount of security has been achieved.

Sexual risk-taking among teenagers has rapidly increased and only during the last decade the existence of Chlamydia has more than tripled.

Background: Within real estate companies assets according to IFRS/ IAS 40 should be valued at fair value, to compare with previous valuation criteria according to which real estate should valued at cost. Two models can be used within IAS 40, these are value at cost and fair value. When valued at cost the real estate value in the balance sheet should be specified at cost. The method chosen by the company should be used for all real estate within the company except for the premises used by the company. Purpose: The purpose of the study is to analyse and evaluate how real estate companies experienced the problems that arose when converting to IAS 40, and to analyse the effects on the companies key ratios as a result of the change of accounting method.

For a long time Lean has been a well-known concept among manufacturers. Theinterest of understanding Lean and the ability to implement it is common amongcompanies. The concept of Lean, used in the right way, can help companies to reducetheir lead times, their complexity and increase the efficiency of the working processes(Hyer och Wemmerlöv, 2002). Unfortunately the work towards increased efficiencyhas primarily been focused on manufacturing and plant work, resulting in that Leanhas been adjusted to these areas. The conclusion of this is that companies don´tprioritize to improve processes such as administrative ones.
