On the difficulty of making social choices

The difficulty of making social choices seems to take on two forms: one that is related to both preferences and the method used in aggregating them and one which is related to the preferences only. In the former type the difficulty has to do with the discrepancies of outcomes resulting from various preference aggregation methods and the computation of winners in elections. Some approaches and results which take their motivation from the computability theory are discussed. The latter institution-free type of difficulty pertains to solution theory of the voting games. We discuss the relationships between various solution concepts, e.g. uncovered set, Banks set, Copeland winners. Finally rough sets are utilized in an effort to measure the difficulty of making social choices.     

The Role of Task Values in Adolescents' Educational Tracks: A Person‐Oriented Approach

The present study examined what kinds of patterns of task‐values adolescents show, and whether these patterns predict their educational and occupational expectations and school track. Six hundred and fourteen adolescents were examined twice before their transition to secondary education and once thereafter. The clustering‐by‐cases analyses identified 6 groups: (1) those who placed a high value on all school subjects, (2) those who did not value any of the subjects, (3) those who valued Finnish and social sciences, (4) those who valued in particular practical and art subjects, (5) those who valued only practical and art subjects, and (6) those who especially valued mathematics and science. The patterns of task‐values also predicted adolescents' occupational and educational expectations.     

The role of work-related personal projects during two burnout interventions: a longitudinal study

Burnout is nowadays a common problem among employees, and a new approach to reduce its extent is needed. This study looked at burnout interventions in terms of personal goals and/or projects. These represent what individuals are striving to achieve, and include work-related goals. Our aim was to examine the extent to which two kinds of burnout intervention, in the form of different types of psychotherapy, influence employees' personal projects. The two types of therapy were psychoanalytic and experiential, both in the form of group therapy. To determine the extent, 62 employees who had contacted the Helsinki Occupational Health Services suffering from severe burnout participated, in the course of a single year, in 16 sessions of either analytic or experiential group psychotherapy. In addition, 28 employees suffering from severe burnout served as controls. All the participants filled in Little's Personal Project Analysis and the Bergen Burnout Indicator one month before the intervention, in the middle of the intervention and one month after the intervention. The results showed that among participants in the intervention groups the level of burnout decreased. Further, the number of work-related personal projects, project-related negative emotions, and tendencies towards negative action, decreased among those in the intervention groups compared to the control group. Moreover, project-related progress, social support and managing project-related emotions increased during the intervention. Finally, the results showed that when the negative emotions related to personal projects decreased during intervention, the level of burnout also decreased.     

Achievement Orientations,School Adjustment,and Well-being: A Longitudinal Study

This study set out to identify the kinds of achievement orientations that adolescents show, and to examine the kinds of antecedents and consequences the use of a particular orientation has. The participants were 734 Swedish adolescents (335 boys and 399 girls) who filled in questionnaires measuring their achievement beliefs and behaviors, depressive symptoms, engagement with school, and norm-breaking behavior. By using clustering-by-cases analysis, five achievement orientation groups were identified: optimism, defensive-pessimism, self-handicapping, and learned helplessness, and a group showing average levels of criteria variables. The results showed further that a decrease in depressive symptoms and an increase in engagement with school predicted a move to the use of optimistic and defensive-pessimistic groups, whereas a reverse pattern predicted a move to the helplessness and self-handicapping groups. Moreover, the optimistic and defensive-pessimistic achievement orientations at Time 1 predicted an increase in engagement with school and a decrease in depressive symptoms later on, whereas self-handicapping and learned helplessness predicted a decrease in engagement with school and increases in depressive symptoms and norm-breaking behavior.     

How Do Efforts to Enhance Career Preparation Affect Peer Groups?

The present study investigated how efforts to enhance career preparation affect peer groups. The participants were 710 9th graders who were randomized into control and intervention groups and assessed 3 times during 1 academic year: at baseline (T1, Fall), immediately after the career preparation intervention (T2, 3 months after baseline), and 5 months after the intervention (T3, Spring). The results showed, first, that maintenance of a stable clique was more likely when most clique members participated in the intervention. Second, it was found that the members of adolescents' cliques resembled each other in respect of the strength of the intervention effect. Finally, the results showed that the similarity of the clique members in career choice preparedness first decreased as a result of the short‐term impact of the intervention but then increased after the intervention was over, suggesting that peer groups were partly responsible for weakening the effect of the intervention. These results have important implications for understanding how peer groups moderate external influences on their members and how the stability of peer groups is affected by these influences.     

Voting paradoxes and referenda

In representational democracies the referenda constitute an additional way for the voters to express their opinions. At the same time they are accompanied by problems of agenda manipulation and interpretation of results. In this context various voting paradoxes and their interrelationships are of considerable interest. In this article particular attention is paid to opinion aggregation paradoxes in referendum institutions. The limits and interrelationships of paradoxes are discussed. Some ways of avoiding paradoxical situations are also outlined. Received: 11 September 1995 / Accepted: 7 January 1997     

A Comparison of Some Distance-Based Choice Rules in Ranking Environments

We discuss the relationships between positional rules (such as plurality and approval voting as well as the Borda count), Dodgsons, Kemenys and Litvaks methods of reaching consensus. The discrepancies between methods are seen as results of different intuitive conceptions of consensus goal states and ways of measuring distances therefrom. Saaris geometric methodology is resorted to in the analysis of the consensus reaching methods.     

Future trends of HRD in the finnish pulp and paper industry

The present article approaches the trends of HRD in the Finnish pulp and paper industry. The recent two decades have introduced several major changes into this field of industry. Technical breakthroughs have led to drastic changes in the competence requirements of the personnel. On the other hand, the boom of mergers and acquisitions in this industry segment has cut down the humber of corporations with world wide operations. Globalization challenges the European labor market, social policy, vocational education as well as HRD practices to develop high value jobs and competencies essential for survival in the labor cost competition.
