This Masters Thesis considers tracking of ground targets. Since ground targets often are difficult to detect with sensors a track is easily lost in ground target tracking. The main question in this thesis is whether information on close targets and observations of them can be used to make the tracking more reliable. An algorithm using Kalman filters and JPDA-association to create a group track for vehicles travelling together has been implemented in Matlab. Using the state of the centre of the group the state of a vehicle in the group can be updated.

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 aims of the present study were to implement and evaluate a three-session Acceptance and Commitment Therapy (ACT) stress management intervention in a non-clinical group of university students (N = 25) and to investigate the importance of practice in an ACT-intervention. A design with pre-test and double post-test was chosen. A comparison was made between a nine-hour ACT-intervention containing practice for the participants, a two-hour lecture on ACT and stress management containing no practice for the participants and a control group. Psychological flexibility was assessed with Acceptance and Action Questionnaire-2 and mindfulness was measured with Kentucky Inventory of Mindfulness Skills. Perceived stress level was measured with Perceived Stress Scale.

This study illustrates how drama methods and career counselling might interact. The aim is to investigate whether drama methods can enhance career counselling methods. Drama is here defined as an umbrella term that includes all forms of action methods used in psychology and education.A literature survey was carried out in parallel with qualitative research interviews. Three professional drama leaders were interviewed separately. This was followed by a group interview with five upper secondary school students, who had all taken a course in drama with a focus on personal development.The findings show that there are common and consistent goals and values between drama and career counselling.

Morbid jealousy is a relatively common problem that often results in relational conflicts, frequently involving violence. Eventually many relationships break down as a consequence of these conflicts. Despite of this morbid jealousy is considered to be under-researched. As regards the treatment of morbid jealousy there is however some evidence that cognitive behaviour therapy is a worthwhile treatment, and there is also a growing body of evidence that jealousy, normal as well as morbid, is an evolutionary adaptation. This study integrates an evolutionary psychological approach with cognitive behaviour therapy in the treatment of morbid jealousy.

The aim of this study is to find out whether there is any difference to be found in the attention ability before and after physical activity. The method used in this study was made of an experimental design. The participants were chosen through a cluster sampling and thereafter divided into a control group and an experimental group. A total of 64 pupils from upper secondary school participated in the study, 25 of them in the experimental group and 39 of them in the control group. Since the measure was repeated, both in respect of time and the comparison between the groups, a mixed design was used.

Studien syftar till att undersöka manliga idrottslag och få en ökad kunskap i gruppdynamikens uppbyggnad och påverkan på laget och dess individer. Metoden som används för detta är tre stycken halvstrukturerade intervjuer samt observationer. Resultatet visade att gruppdynamiken är en väldigt vikig del av idrottslag. Stämningen som finns är byggd på gamla traditioner om hur män i grupp ska fungera samt på en rollsättning som görs i laget. Detta i sin tur skapar en speciell ton och kommunikation inom laget som främjar vi-känslan och samhörigheten.

In Sweden approximately ten percent of all children grows up in a family where at least one parent is having an alcohol related addiction. Since 1998 the development of group activities for children in this situation has been immense. The aim of group activities is to break the child's isolation and make them feel that they are not lonely in their experiences, give them knowledge about addiction and relive the pressure of guilt and responsibility.In a comparative study we examined studied how two different group activity models one with the conception of illness and one without, use the children's network to support the group process. The aim was also to find each models definition of the "normal family", since we understood the groupactivity as a part in the normalization process. We reached our aim through interviews with group leaders and by literature studies.

This study investigates the relationship strategies the group Forest Stewardship Council (FSC) certification holder has with the forest owners. The (FSC) standard enables an organization to manage a group of forest management units under a single certificate, a process referred to as group certification. Some certificate holders want a close relationship with the forest owner before they are offered to become part of their certificate. Other certificate holders have less strict demands on a close relationship with the forest owner before they are offered to become part of their certificate. The study shows that it is in many ways desirable to have a close relationship between forest owner and group certification holder..

This paper was part of the ongoing cooperation between the Swedish Civil Aviation Authority and the Department of Psychology at Lund University. The purpose of this study was to develop a self-report measure regarding human factors, for the air traffic controllers to fill out before they start their working shift. This in order to aid the team leaders in their judgment regarding the air traffic controller's ability to perform at the right safety level. The self-report measure would also serve as an aid for the air traffic controllers who have a responsibility regarding their own performance. If successful this self-report measure would make it easier for the air traffic controllers to be alert regarding certain factors that can have a large impact on their performance.

Denna studie undersöker och beskriver den psykiska hälsan hos en grupp barn och ungdomar placerade i familjehem i en större stad i södra Sverige. 42 barn och ungdomar i åldrarna 11 till 20 år valdes ut från en kohort bestående av 52 som vid något tillfälle under 2005 befann sig placerade i familjehem. Till barnen administrerades Youth Self Report (YSR), till en av familjehemsföräldrarna Child Behavior Checklist (CBCL) och till barnens lärare Teacher´s Report Form (TRF). Data från barnens socialakter samlades också in. Totala problemskalorna för CBCL och TRF visade att andelen barn på klinisk nivå uppgick till 23 % medan motsvarande siffra för YSR var 9 %.
