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.

Aspiration-based utility functions in a planning model for timber flow management.

The study presents a theory of utility models based on aspiration levels, as well as the application of this theory to the planning of timber flow economics. The first part of the study comprises a derivation of the utility-theoretic basis for the application of aspiration levels. Two basic models are dealt with: the additive and the multiplicative. Applied here solely for partial utility functions, aspiration and reservation levels are interpreted as defining piecewisely linear functions. The standpoint of the choices of the decision-maker is emphasized by the use of indifference curves. The second part of the study introduces a model for the management of timber flows. The model is based on the assumption that the decision-maker is willing to specify a shape of income flow which is different from that of the capital-theoretic optimum. The utility model comprises four aspiration-based compound utility functions. The theory and the flow model are tested numerically by computations covering three forest holdings. The results show that the additive model is sensitive even to slight changes in relative importances and aspiration levels. This applies particularly to nearly linear production possibility boundaries of monetary variables. The multiplicative model, on the other hand, is stable because it generates strictly convex indifference curves. Due to a higher marginal rate of substitution, the multiplicative model implies a stronger dependence on forest management than the additive function. For income trajectory optimization, a method utilizing an income trajectory index is more efficient than one based on the use of aspiration levels per management period. Smooth trajectories can be attained by squaring the deviations of the feasible trajectories from the desired one.

A participatory approach to tactical forest planning.

The paper examines the needs, premises and criteria for effective public participation in tactical forest planning. A method for participatory forest planning utilizing the techniques of preference analysis, professional expertise and heuristic optimization is introduced. The techniques do not cover the whole process of participatory planning, but are applied as a tool constituting the numerical core for decision support. The complexity of multi-resource management is addressed by hierarchical decision analysis which assesses the public values, preferences and decision criteria toward the planning situation. An optimal management plan is sought using heuristic optimization. The plan can further be improved through mutual negotiations, if necessary. The use of the approach is demonstrated with an illustrative example, it's merits and challenges for participatory forest planning and decision making are discussed and a model for applying it in general forest planning context is depicted. By using the approach, valuable information can be obtained about public preferences and the effects of taking them into consideration on the choice of the combination of standwise treatment proposals for a forest area. Participatory forest planning calculations, carried out by the approach presented in the paper, can be utilized in conflict management and in developing compromises between competing interests.

Pre-harvest measurement of pine stands for sawing production planning.

To enhance the utilization of the wood, the sawmills are forced to place more emphasis on planning to master the whole production chain from the forest to the end product. One significant obstacle to integrating the forest-sawmill-market production chain is the lack of appropriate information about forest stands. Since the wood procurement point of view in forest planning systems has been almost totally disregarded there has been a great need to develop an easy and efficient pre-harvest measurement method, allowing separate measurement of stands prior to harvesting. The main purpose of this study was to develop a measurement method for pine stands which forest managers could use in describing the properties of the standing trees for sawing production planning. Study materials were collected from ten Scots pine stands (Pinus sylvestris) located in North Häme and South Pohjanmaa, in southern Finland. The data comprise test sawing data on 314 pine stems, dbh and height measures of all trees and measures of the quality parameters of pine sawlog stems in all ten study stands as well as the locations of all trees in six stands. The study was divided into four sub-studies which deal with pine quality prediction, construction of diameter and dead branch height distributions, sampling designs and applying height and crown height models. The final proposal for the pre-harvest measurement method is a synthesis of the individual sub-studies. Quality analysis resulted in choosing dbh, distance from stump height to the first dead branch (dead branch height), crown height and tree height as the most appropriate quality characteristics of Scots pine. Dbh and dead branch height are measured from each pine sample tree while height and crown height are derived from dbh measures by aid of mixed height and crown height models. Pine and spruce diameter distribution as well as dead branch height distribution are most effectively predicted by the kernel function. Roughly 25 sample trees seems to be appropriate in pure pine stands. In mixed stands the number of sample trees needs to be increased in proportion to the intensity of pines in order to attain the same level of accuracy.

Estimation of cutting volume with three inventory methods for harvest planning in Canadian boreal forests.

Two methods of pre-harvest inventory were designed and tested on three cutting sites containing a total of 197 500 m3 of wood. These sites were located on flat-ground boreal forests located in northwestern Quebec. Both methods studied involved scaling of trees harvested to clear the road path one year (or more) prior to harvest of adjacent cut-blocks. The first method (ROAD) considers the total road right-of-way volume divided by the total road area cleared. The resulting volume per hectare is then multiplied by the total cut-block area scheduled for harvest during the following year to obtain the total estimated cutting volume. The second method (STRATIFIED) also involves scaling of trees cleared from the road. However, in STRATIFIED, log scaling data are stratified by forest stand location. A volume per hectare is calculated for each stretch of road that crosses a single forest stand. This volume per hectare is then multiplied by the remaining area of the same forest stand scheduled for harvest one year later. The sum of all resulting estimated volumes per stand gives the total estimated cutting-volume for all cut-blocks adjacent to the studied road. A third method (MNR) was also used to estimate cut-volumes of the sites studied. This method represents the actual existing technique for estimating cutting volume in the province of Quebec. It involves summing the cut volume for all forest stands. The cut volume is estimated by multiplying the area of each stand by its estimated volume per hectare obtained from standard stock tables provided by the governement. The resulting total estimated volume per cut-block for all three methods was then compared with the actual measured cut-block volume (MEASURED). This analysis revealed a significant difference between MEASURED and MNR methods with the MNR volume estimate being 30 % higher than MEASURED. However, no significant difference from MEASURED was observed for volume estimates for the ROAD and STRATIFIED methods which respectively had estimated cutting volumes 19 % and 5 % lower than MEASURED. Thus the ROAD and STRATIFIED methods are good ways to estimate cut-block volumes after road right-of-way harvest for conditions similar to those examined in this study.

Information Technology Development Needs in Community Pharmacies : A Strategic Approach

In the context of health care, information technology (IT) has an important role in the operational infrastructure, ranging from business management to patient care. An essential part of the system is medication management in inpatient and outpatient care. Community pharmacists strategy has been to extend practice responsibilities beyond dispensing towards patient care services. Few studies have evaluated the strategic development of IT systems to support this vision. The objectives of this study were to assess and compare independent Finnish community pharmacy owners and staff pharmacists priorities concerning the content and structure of the next generation of community pharmacy IT systems, to explore international experts visions and strategic views on IT development needs in relation to services provided in community pharmacies, to identify IT innovations facilitating patient care services and to evaluate their development and implementation processes, and to assess community pharmacists readiness to adopt innovations. This study applied both qualitative and quantitative methods. A qualitative personal interview of 14 experts in community pharmacy services and related IT from eight countries and a national survey of Finnish community pharmacy owners (mail survey, response rate 53%, n=308), and of a representative sample of staff pharmacists (online survey, response rate 22%, n=373) were conducted. Finnish independent community pharmacy owners gave priority to logistical functions but also to those related to medication information and patient care. The managers and staff pharmacists have different views of the importance of IT features, reflecting their different professional duties in the community pharmacy. This indicates the need for involving different occupation groups in planning the new IT systems for community pharmacies. A majority of the international experts shared the vision of community pharmacy adopting a patient care orientation; supported by IT-based documentation, new technological solutions, access to information, and shared patient data. Community pharmacy IT innovations were rare, which is paradoxical because owners and staff pharmacists perception of their innovativeness was seen as being high. Community pharmacy IT systems development processes usually had not undergone systematic needs assessment research beforehand or evaluation after the implementation and were most often coordinated by national governments without subsequent commercialization. Specifically, community pharmacy IT developments lack research, organization, leadership and user involvement in the process. Those responsible for IT development in the community pharmacy sector should create long-term IT development strategies that are in line with community pharmacy service development strategies. This could provide systematic guidance for future projects to ensure that potential innovations are based on a sufficient understanding of pharmacy practice problems that they are intended to solve, and to encourage strong leadership in research, development of innovations so that community pharmacists potential innovativeness is used, and that professional needs and strategic priorities will be considered even if the development process is led by those outside the profession.

Asemakaavoitus Helsingin seudun kasvun hallinnassa

Many Finnish municipalities need to control their growth. In this research growth is understood as developments of land utilisation and also as a wide range of other changes that have mainly ap-peared as a result of a long term growth in population. The development growth control contains four areas: 1. adequate productivity of town planning, 2. stationing the growth to needs led and for sustainable developments, 3. quality of the developing environment, and 4. producing growth with communicative and transparent process. The aim of the research is to represent connection between town planning and development growth control. Research defines the role of town planning in the municipalities development growth control. In addition research focuses on links between town planning and development growth control in history, present and in the development work for the future. According to the hypothesis the extensive examination of town planning enables better growth control and promotes appropriate response to municipal changes regarding housing delivery. As an example there are five outskirt municipalities in the Helsinki region. They are called Kirkkonummi, Vihti, Nurmijärvi, Tuusula and Sipoo. The decision was to use examples based on a contingence theory. According to the theory there is no one correct way to operate. Therefore development should be based on individual municipal needs. In the research, municipality s needs were collected by 20 semi- structured interviews from municipal officials. In addition there were group interviews in Uusimaa Regional Council and in Uusimaa Regional Environmental Centre. There was also secondary material collected from official papers and statistics. Operationalisation was the analysis tool between empiric and literature reviews. The role of town planning has evolved during the 20th century from a more simple town plan level to operative stage in town planning hierarchy. Outskirt municipalities town planning was established during the 1960s. Since then one of the most important aims in the town planning has been to produce growth and building possibilities. Currently the challenge is to reach the satisfying rate of productivity and to meet increased housing demand. Other challenges include locating the appropriate geographical areas for growth; and the balance between required developments and planning permission decisions. Findings concluded that town planning should be more viable and it should have better ability to co-operate and operate in the changing operational environment. Municipality s ability to receive growth can increase and growth control can advance by planned and workable town planning. It is essential to take wide perspective of the each municipality's unique needs to improve productivity rather than to focus simply on productivity.

Asukkaan Helsinki? : Tapaustutkimus vuorovaikutteisuudesta kaupunkisuunnittelussa

This study examines the interaction between inhabitants and urban planning. In addition to traditional methods of participation there can be seen an increasing need to find new channels and means to influence on one´s environment. Hearing of inhabitants during planning is hoped to decrease the amount of claims and this way to speed up the planning process. Discussion that emphasizes competitiveness and innovativeness in planning has brought out the role of inhabitants as selective consumers and end users. This extension of civil perspective completes the thought of participation in city planning and adds the pressure on developing the interaction and user orientation. The aim of the study is to point out the present situation of inhabitant´s participation and influencing in Helsinki. Helsinki City Planning Department opened a new information and exhibiotion hall called Laituri in 2008. Laituri provides the latest information about planning projects in Helsinki and temporary exhibitions as well as it operates as communication channel and information point for the department. In this study Laituri is examined as a case study of interaction between citizen and planner. The study is divided into two principal themes. The aim is to research action and interactivity at Laituri from the inhabitants´and planners´point of view. The qualitative study has inquiries, interview surveys and observation as research methods. Empiricial data of the study consists of three parts which complement each other: Laituri operational reseach, inquiry directed to the members of Laituri team and interviews of three experts. The aim is to find answers to questions like, does Laituri reach the citizens and will the opportunities to participate improve along Laituri. The study examines also how the local knowledge of inhabitants will come across to planners and further to planning. The study combines discussions of inhabitants´ influencing in Finnish society and science community. Cornerstones of the study are inhabitant participation, interaction and local knowledge in urban planning. The theory behind the study is communicative planning theory. In addition the theory consists of key concepts. The study introduces a concept of Inhabitant´s Helsinki, which reflects the inhabitant as customer-citizen who is an active product developer in participative urban planning. According to the research results the experts of Laituri and majority of inhabitants in Helsinki experience that the inhabitant´s possibilities to participate will improve along Laituri. However half of the citizens in Helsinki believe that local knowledge and ideas will only have minor impact on the final plan. According to city dwellers the present practise used by Helsinki City Planning Department supports only partially adequate interaction. The experts of Laituri experience that the role of Laituri is first of all forum of communication and discussion channel instead of effective local data collector. Based on the results the study introduces a model of inhabitant´s participation field. According to the model Laituri can be seen as phenomenom in Helsinki urban planning which has the elements of network municipality. The planner is more like diplomatic trend-setter and visionary. The inhabitant of Helsinki is an expert in city living and participative producer of local knowledge. Participation methods are increasingly segmented and tailored in every plan and project. The study argues that Inhabitant´s Helsinki is a pluralistic milieu in constant pressure for change. Therefore reaching the everyday life experiencies of inhabintants should be at higher degree in Helsinki City Planning Department´s operations.
