The main purpose of this dissertation was to relate a study within the framework of Peer Student Group Research to the basic Process-Product Paradigm for Research on Teaching. Information about previous research within this field was given in the chapter on background. A total of 287 peer students at the Department of Education, Umeå University and at the teacher training colleges at Umeå and Luleå participated in this study. Thirty-one students worked individually and constituted a control group. The remaining 256 students were divided into 64 groups. Each group consisted of four students and was videoed during the problem-solving phase (60 minutes). The task dealt with a discipline case in the Swedish compulsory school. This case was discussed on the basis of four different psychological theories. A 2(Content, Group vs. Individual Content) X 2(Cohesiveness, High vs. Low Cohesiveness) X 2(Credit, Group vs. Individual Credit) design was used. A mediating model, i.e. Contribution(Analytical vs. Structural Contribution) X Persistence(Task Persistent vs. Task Non-Persistent Contribution) was used to observe the processes. Two of the videoed groups were analysed naturalistically. The results were measured psychometrically by means of an ANOVA. The ANOVA analysed main effects and interactions between the factors for the four process variables and for the product variable. The results of this study revealed the importance of studying Educational Productivity, i.e. both the process and the product. Furthermore, the study demonstrated that interactions could be discovered with psychometric methods but not with naturalistic methods. On the other hand, the naturalistic method revealed more sensitively how the group members worked and how they attempted to solve their task. The traditional assumption of group work vs. individual work was falsified. Individuals did better than groups on this type of problem. The results were discussed in both psychometric and naturalistic terms. / <p>Diss. Umeå : Umeå universitet, 1996</p> / digitalisering@umu

The aims of the dissertation were to assess: the psychological peculiarities of Lithuanian Afghanistan war veterans; the risk factors and the intensity of risk factors relations with posttraumatic reactions. A sample of 268 Lithuanian men who served in the Soviet Army in 1979–1989 was investigated on the average 17 years after the service: 174 men – study group and 94 – comparison group. The questionnaire was completed focusing on life-threatening experience, posttraumatic stress reactions, and mediating variables – social support, adaptation, sense of coherence, consumption of alcohol and drugs (HTQ, TSC-35, CSS, SOC13, structured and open questions). Lithuanian Afghanistan war veterans have more long-term psychological after-effects than the comparison group. Lithuanian Afghanistan war veterans experienced significantly more service-related and non-service-related traumatic events and conditions. Their adaptation after the service and nowadays were poorer and alcohol consumption is far more hazardous than in the comparison. Sense of coherence, adaptation after the service, violent assault, loss of the family member and alcohol consumption nowadays predict PTSD. The model of Afghanistan war veterans’ psychological after-effects is presented and discussed. / Tyrimo tikslai buvo nustatyti: 1) kokie psichologiniai ypatumai būdingi Lietuvos Afganistano karo veteranams; 2) veiksnius, susijusius su vyrų dalyvavusių Afganistano kare potrauminės simptomatikos išreikštumu ir įvertinti tų veiksnių sąsajų su potraumine simptomatika stiprumą. Tyrimo dalyviai – 268 Lietuvos vyrai atlikę privalomąją karo tarnybą Sovietų armijoje 1979-1989 metais. Tiriamoji grupė – 174 vyrai tranavę Afganistano-Sovietų Sąjungos kare, palyginamoji grupė – 94 vyrai tarnavę SSRS teritorijoje, kur karo veiksmų nebuvo. Jie buvo apklausti vidutiniškai 17 metų po sugrįžimo iš tarnybos. Klausimyną sudarė Harvardo traumos klausimynas, Traumos simptomų klausimynas, Paramos krizėje skalė, Vidinės darnos skalė ir struktūruoti bei atviri klausimai apie trauminį patyrimą, potraumines pasekmes bei tarpinius kintamuosius – prisitaikymą, socialinę paramą, vidinę darną bei alkoholio ir narkotikų vartojimą. Lietuvos Afganistano karo veteranų ilgalaikiai potrauminiai padariniai yra sunkesni, nei palyginamosios grupės. Lietuvos Afganistano karo veteranų traumininė patirtis, susijusi su tarnyba ir viso gyvenimo yra sunkesnė, adaptacija iš karto po tarnybos ir dabartiniu metu prastene bei jiems labiau būdingas žalingas alkoholio vartojimas dabartiniu metu, nei palyginamosios grupės vyrams. Potrauminio streso sutrikimo pasireiškimą geriausiai prognozavo vidinė darna, prisitaikymas po tarnybos, patirtas smurtinis užpuolimas, šeimos nario netektis ir alkoholio vartojimas dabartiniu...

During recent years, technology has played a crucial role in shaping the retail industry. Digitalisation and e-commerce are seen as the future of retailing. However, big online retailers have shown increasing interest in offline shopping by heavily investing in brick and mortar stores. The strategy of a retailer making use of both offline and online channels is called omnichannel strategy. This study investigates why online retailers are investing in physical stores and what is the impact of this decision on their customer base. The study uses a two-step research. First, a case study on the Swedish retailer NetOnNet is conducted to confirm the theoretical framework and build the research model. Then, a quantitative research with questionnaire is used to investigate the impact of an omni-channel strategy on the consumers’ attitudes towards the retailer. The results show that awareness and control are the factors most affected by an omni-channel strategy. Instead, having both an online and offline presence does not have a relevant impact on the factors trust, perceived risk and personalisation.
