Introduction: In January 2005, a nationwide mandatory bicycle helmet law for children under the age of 15 was introduced in Sweden. In the current study, the effect of this law was evaluated by analyzing national trends in hospital admissions due to bicycle-related head injuries during the period 1998-2011.Methods: An interrupted time-series design with segmented regression analysis was used to evaluate the intervention effect on head injuries as a percentage of all injuries (%HI) among cyclists in age- and sex-specific groups. Effect was measured as a change in level and/or slope of the trend at the time of legislation.Results: A total of 35261 cyclists (0-54 years) were hospitalized due to a bicycle injury during the study period. Linear regression analyses of the entire study period (not segmented) showed significant year-to-year decreases in the %HI of 1.3-1.7% in all age and sex-specific groups (p < .0001). Results from the segmented regression analysis showed that, at the time of legislation, a significant drop in level occurred among males under 15 years (-4.5% [95% CI: -7.7% to -1.3%], p = .01) and a significant change in slope occurred among Females aged 30-54 years (-1.6% [95% CI: -2.9% to -0.2%], p = .025).Conclusions: The law seems to have had an effect on males in the target population (<15 years).

The red-tailed monkey (Cercopithecus ascanius) is a small, alert and active animal inhabiting forests with dense vegetation and as such hard to observe in its natural habitat. The principal aim of this study was to scrutinize whether the methods, previously used in a behavioural study of the blue monkey (Cercopithecus mitis) can be applied in studies of the red-tailed monkey?s behaviour as well. Additionally, habitat preference and foraging behaviour of the red-tailed monkey were examined. The study was carried out between the 16th and the 22nd of March 2009 in the Sabaringo forest, located on the western border of the Masai Mara National Reserve.

The aim of this piece of work is to highlight and investigate young female?s motivation in participation of P.E classes and the degree to which the content of classes affect their motivation. To support this piece of work two theories have been utilized, the Self-determination Theory and a gender related perspective theory. The research consists of six qualitative interviews of young Females who are perceived to be less motivated. These interviews focus on their views and attitudes in relation to P.E within the Swedish high school setting.

AbstractThere is a general perception that women are victims and men are the perpetrators of sexual offense. Female perpetrators of sexual crimes have been neglected in the research literature, because female sex offenders do not live up to preconceptions of female as motherly and caring. Females tend to be responsible for a very small portion of all crimes and are estimated to account for 1-2% of all sexual offenses. Theories use to discuss female sex offending include neutralization of behavior, mental health and feminist theory. The aim of the present study was to describe female sex offenders and examine the relationship between the perpetrator and the victim by analyzing court judgments.

Erythropoiesis is a complex and carefully controlled process which is mainly regulated by erythropoietin. Using flow cytometry cells in a blood sample can be analyzed one by one. ADVIA 2120 using flow cytometry for analysis of red blood cells (RBC) and reticulocytes. Red blood cell distribution width (RDW) is a component of the RBC method. RDW indicates size variation on erythrocytes and is measured as a percentage of the mean cell volume (MCV). By measuring the RDW anemia can be divided into makrocytic, microcytic or normocytic. Reticulocytes refract light more strongly than red blood cells because they contain some cellular debris. The number of reticulocytes in the peripheral blood reflects erythropoiesis in the bone marrow. The purpose of this project was that by approved methods to establish reference ranges for the parameters, RDW and reticulocyte counts.The individuals who participated in the study, n=124, were considered healthy and had varying ethnicity. Reference subjects had not donated blood the last six months and participation in the study was voluntary.The statistic evaluation includes examination of distribution, and reference ranges for both men and women were established using the 2.5:t and 97.5:t percentiles. The calculated reference interval for RDW was between 12.0 ? 14.3% and the calculated reference interval for reticulocytes was between 38.0 ? 112.8 x109 cells/L. The results showed a significant difference between males and Females for the parameter reticulocytes was seen. The difference indicates that different reference ranges should be established for men and women (p<0,0001). No significant difference between males and Females were seen for RDW (p=0,74) indicating that the same reference ranges can be used for both men and women. .

The purpose of this essay is to look upon the gender structure in Sweden, during the late Middle Ages. Mainly I focus on how the church viewed men and women, since the material of my research, the miracle stories of three saints, was found credible and was written down by churchmen. The saints, whose miracles I have studied, are Birgitta Birgersdotter and Katarina Ulfsdotter of Vadstena and Niklas Hermansson of Linköping. These miracles have earlier been studied by the historian Anders Fröjmark, who has noticed that there are fewer heeled women than men figuring in the miracles. Because of this, Fröjmark draws the conclusion that women were less able to leave their homes and travel as pilgrims to the holy sites of the saints.

AimThe aim of the present investigation was to study the side distribution (right, left) and possible gender differences in terms of anterior cruciate ligament (ACL) injuries in different sports.MethodThis Register study comprises a total of 27856 subjects from the Swedish National Anterior Cruciate Ligament Register. Side- distribution and possible gender differences were analyzed. The different sports consisted of aerobics, alpine skiing, basket, cross-country skiing, dancing, enduro, floorball, gymnastics, handball, ice hockey/bandy, martial arts, outdoor activities, racket sports, snowboard, soccer, and volleyball. Due to injuries that had occurred in the traffic and at work 5076 subjects were excluded. Statistical data have been analyzed with one way ANOVA and x2 test and the Tukey post hoc test has also been used.

The wild boar Sus scrofa population in Sweden has increased rapidly in the last decades which has led to conflicts among stakeholders, for example due to crop damages in agriculture. Thus, there is an urgent need of quantified goals and effective strategies for wild boar management. To develop such strategies, knowledge on population dynamics is fundamental. In this study a deterministic matrix model was used to estimate population growth, based on previously published data. The exponential growth rate for a wild boar population was calculated to 1.48.

Abstract Aim: Since there is a lack of research based educational interventions concerning the relationship between coaches and young athletes, the aim of this study was to implement and examine the effects of sport psychology intervention for coaches in a track and field club. The research questions were: What are the effects of an educational intervention for coaches, with focus on a motivational climate, on: A) the coaches´ coaching approach B) their athletes´ goal orientation and C) their athletes´ perceived competitive anxiety?Method: The coach education stretched over two months and consisted of four two-hour lessons with focus on motivational climate, goal orientation and sport anxiety. Six coaches (three Females, three males), aged 38-52 (M=44.33 years, SD=4.84) and their 59 athletes (27 males and 32 Females) aged 12-14 (M=13.10 years, SD=0.82), participated in the study. A control group of 35 athletes (10 males and 25 Females), of the same age (M=13.46 years, SD=0.70) and with similar demographic data, was also recruited.

The mouse (Mus musculus) is the most commonly used mammal in biomedical research and can easily be restrained by both hand and by a device. Restraining animals causes stress that not only decreases the animal?s wellbeing, but may also influence the research results. The first aim of this study was to train mice to voluntarily stand still using positive reinforcement training. Another benefit of teaching a mouse to stand still is that you can avoid anaesthesia for some procedures.

Non-contact anterior cruciate ligament (ACL) injuries is a serius and traumatic injury to the knee that is common in female soccer players and often force the player to quit or lower the level of activity because of lost stability in the knee or from fear to suffer  a new injury. Female soccerplayers have a higher risk than their male counterparts to get an ACL rupture and especially adolescent Females have a high risk. The most common causes to a non-contact ACL rupture is side-cutting manuvers and landing after jumping. Every other player with an ACL rupture develops osteoarthritis within 10-15 years from the time of injuryResults: The higher risk for Females to incur a ACL rupture is due to smaller intercondylar notch, they?re in the follicular or ovulatory phase of their menstrual cycle, increased knee laxity, dominance in the quadriceps muscles, flexion in hip and valgus movement in the knee.

The objective was to examine the frequency of unwanted behaviors in the Swedish feline population and what factors in the environment, inheritance and past life that have an influence on the frequency. SLU?s web poll generator was used to create a web poll which insinuated that it was a poll with objective to make an inventory of the Swedish feline population. I wanted to avoid that only owners to cats with unwanted behaviors answered the poll. The web link to the poll was sent to SLUs students and posted on Internet forums for people interested in cats.

AimThe aim of this study was to investigate if the Swedish elite soccer teams, both males and Females, have preventive strategies to reduce the risk of muscular injuries in the posterior thigh.MethodA survey was created and sent by mail to all (n=28) Swedish elite soccer teams in allsvenskan (both males and Females) to be answered by the head of physical exercise within each team. A pilot study regarding the survey was performed by two soccer coaches on elite level and was revised afterwards. The survey was conducted between May through July 2013. In total, 18 soccer teams participated in this survey.Results10 soccer teams did not respond to the survey, which resulted in a drop out of 36%. Preventive strategies to reduce the risk of muscular injuries in the posterior thigh existed in 16 of the teams.

The purpose of this Master?s thesis is to investigate if there might be a possiblecorrelation between young women´s fascination with the vampire narrative andtheir search for identity in the late modern age. With the help of contemporarysociological studies in the field of the late modern man and today?s youth culture,I?ve chosen to do qualitative interviews with eight young women in order to examinehow today?s society affects their process of identification. Lately we?ve been ableto see an enormous interest for books that deal with the vampire saga, and while thereaders are mostly young Females, it brought me to ask the question why the combinationof teenage drama and vampires seems to be such a winning concept.We live in a time where most young Females experience a lot of pressure trying to addup to the demands of society, and as the media keep producing images of youngwomen being thin and looking like supermodels, most teenagers feel a lot of pressureand anxiety trying to live up to such unnatural ideals that in the long run might lead tovarious health issues and eating disorders.As a result of this thesis I?ve found that the vampire narrative answers to some ofthe existential needs we have as members of a late modern society.
