The reality behind archaeological textilestudy is holistic, embracing many different aspects of society. The presentation of textiles has in my opinion become old-fashioned. I will show in my paper that Jonathan Adams? `seven constraints´ model, developed for research on ancient ships, can also be applied to textile research.

Leder kastrering av hanhundar till bättre djurvälfärd?

Castration of dogs holds many reasons and opinions, therefore methods, traditions and rea-sons vary. The approaches have during time changed from mostly surgical castrations to also including hormonal treatments. Castration is used to control the dog's reproductive abilities, for medical reasons and to possibly rectify problems of behavioral nature. How common a particular method of castration is in a country is highly dependent on the country's traditions. In Sweden it is most common with castration for medical reasons, such as possible elimina-tion of diseases, for example, benign colorectal tumors.

Stress och välmående i restaurangbranschen : Sex gymnasielevers uppfattning om restaurangbranschens sociala arbetsmiljö och utbildningens förberedelse för den

Most swedish newspapers have a homepage where their news are presented. Existing guidelines describing how to write for the web often recommends you to keep it short and stay objective. But how about longer pieces of content presented in the print version? What will become of reports, interviews and essays as we?ve come to know them as the printed newspaper goes digital?Interviews with representatives of five swedish newspapers shows that the extent to wich content is being published on the web is connected to the overall purpose of the web presence.
