Examining effectiveness of an immigrant labor market integration intervention. The role of acculturation, discrimination, self-efficacy, outcome expectances, action and coping planning.

The designing of effective intervention tools to improve immigrants’ labor market integration remains an important topic in contemporary Western societies. This study examines whether and how a new intervention tool, Working Life Certificate (WLC), helps unemployed immigrants to find employment and strengthen their belief of their vocational skills. The study is based on quantitative longitudinal survey data from 174 unemployed immigrants of various origins who participated in the pilot phase of WLC examinations in 2009. Surveys were administered in three waves: before the test, right after it, and three months later. Although it is often argued that the unemployment among immigrants is due either to their lack of skills and cultural differences or to discrimination in recruitment, scholars within social psychology of behavior change argue that the best way of helping people to achieve their goals (e.g. finding employment) is to build up their sense of self-efficacy, alter their outcome expectances in a more positive direction or to help them to construct more detailed action and coping plans. This study aims to shed light on the role of these concepts in immigrants’ labor market integration. The results support the theories of behavior change moderately. Having positive expectances regarding the outcomes of various job search behaviors was found to predict employment in the future. Together with action and coping planning it also predicted increase in job search behavior. The intervention, WLC, was able to affect participants’ self-efficacy, but contrary to expectations, self-efficacy was found not to be related to either job search behavior or future labor market status. Also, perceived discrimination did not explain problems in finding employment, but hints of subtle or structural discrimination were found. Adoption of Finnish work culture together with strong family culture was found to predict future employment. Hence, in this thesis I argue that awarding people diplomas should be preferred in immigrant integration training as it strengthens people’s sense of self-efficacy. Instead of teaching new information, more attention should be directed at changing people’s outcome expectances in a more positive direction and helping them to construct detailed plans on how to achieve their goals.

The effectiveness of infrainguinal percutaneous transluminal angioplasty in the treatment of critical limb ischaemia

Critical chronic lower limb ischaemia (CLI) is the most severe form of peripheral arterial disease. Even though the treatment of CLI has evolved during the last decade, CLI is still associated with considerable morbidity, mortality and a decreased quality of life, in addition to a large financial impact on society. ---- Bypass surgery has traditionally been considered the approach of choice to treat CLI patients in order to avoid amputation. However, there are increasing data on the efficacy of endovascular revascularization procedures, such as percutaneous transluminal angioplasty (PTA), to achieve good leg salvage rates as well. Data gathered on all the 2,054 CLI patients revascularized at the Helsinki University Central Hospital between 2000 and 2007 were retrospectively analyzed. This patient cohort was used to compare the results of infrainguinal PTA and bypass surgery as well as to investigate predictors of failure after PTA. This study showed that infrainguinal PTA and bypass surgery yielded rather similar results in terms of survival, amputation-free survival and freedom from any re-intervention. When the femoropoliteal segment was treated, leg salvage was significantly better in the bypass surgery group, whereas no significant difference was observed between the two treatment methods when the revascularization extended to the infrapopliteal segment. PTA resulted in a significantly lower freedom from surgical re-interventions when compared to surgical revascularization. In this study the most important predictors of poor outcome after PTA for CLI were cardiac morbidity, nonambulatory status upon hospital arrival, and gangrene as a manifestation of CLI. Thus, when feasible, PTA seems to be a valid alternative for bypass surgery in the treatment of CLI provided that active redo-surgery is utilized. The optimal revascularization strategy should always be sought for each CLI patient individually considering the clinical state of the leg, the occlusive lesions to be treated, co-morbidities, life-expectancy, and the availability of a suitable vein for bypass.
