Multiple input transfer function noise modelling in the time and frequency domain:empirical evidence from Monte Carlo simulations

In the present study we have evaluated two competing methods for estimation of the impulse response weights used in the identification of transfer function models:a time domain method involving biased regression techniques and a frequency domain method utilizing a discrete Fourier transform of the cross-covariance system of the transfer function model. The algorithms were implemented on a VAX-8800 computer at the Computing Center at Åbo Akademi. The evaluation of the competing methods was carried out by simulations of different transfer function noise model structures. The models are essentially the same as those of Edlund, but we have used a far greater number of replications in the cases tested. Furthermore, we have used actually identified and estimated autoregressive integrated moving-average models of the residuals in the identification procedure of impulse response weights, in contrast with Edlund who only used theoretical noise models in filtering the input and output series. After a shot discussion of the underlying theory, we present the procedures and results of the empirical testing.     

Bargaining over a finite set of alternatives

We analyze bilateral bargaining over a finite set of alternatives. We look for "good" ordinal solutions to such problems and show that Unanimity Compromise and Rational Compromise are the only bargaining rules that satisfy a basic set of properties. We then extend our analysis to admit problems with countably infinite alternatives. We show that, on this class, no bargaining rule choosing finite subsets of alternatives can be neutral. When rephrased in the utility framework of Nash (1950), this implies that there is no ordinal bargaining rule that is finite-valued. Professor Sertel passed away on January 25, 2003.     

The Emergence of a Specific Kind of Individualization Habitus Among Divorced Women

Previous research has consistently found that divorce is associated with psychological distress. This study expands existing research by considering age, education, employment, income, length of divorce, number of children, and economic hardship as predictors of postdivorce psychological distress among divorced women in Iran. This study examines 800 divorced women in Iran 30 to 48 years old who had been divorced for no more than 2 years. Results demonstrated that education, number of children, and economic hardship together predict 63.6% of the variance in psychological distress among divorced women. Economic hardship was found to be the strongest contributor. Recommendations for researchers and implications for clinicians are discussed.     

A Randomized,Waiting-List-Controlled Study Shows That Brief,Mindfulness-Based Psychological Interventions Are Effective for Treatment of Women’s Low Sexual Desire

We evaluated two treatment conditions for low sexual desire in women: one where participants were administered a mindfulness-based treatment protocol and another with exercises focusing on scheduled sex and motivations for sex in addition to the aforementioned protocol. Seventy women (M_age 39.2, SD = 9.8) with complaints of low sexual desire were randomly allocated to one of these treatment conditions or a waiting-list condition. Participants attended four individual sessions and completed homework exercises. Questionnaire data were collected before and after treatment and at follow-ups three and six months later. Primary outcomes were the Female Sexual Function Index (FSFI) desire subdomain and the Sexual Interest and Desire Inventory–Female (SIDI-F). Secondary outcomes were the Female Sexual Distress Scale–Revised (FSDS-R), the Revised Dyadic Adjustment Scale (RDAS), the Perceived Relationship Quality Components Inventory (PRQC), and the Brief Symptom Inventory–18 (BSI-18). Women in both treatment conditions reported significantly higher sexual desire (FSFI desire d = 0.75 to 1.06) immediately following treatment, compared to the waiting list. Improvements were sustained at follow-up, accompanied by improvements in some secondary outcomes. We found no significant differences between the treatment conditions in terms of treatment effectiveness. Our study adds to the literature suggesting that mindfulness-based treatments are suitable options for treating low sexual desire in women.     

Minimal conversely consistent extension of the men-optimal solution

This study pertains to two-sided, one-to-one matching problems and considers the best-known solution concept: the men-optimal solution. The men-optimal solution fails to satisfy consistency as well as converse consistency. Furthermore, the minimal consistent extension of the men-optimal solution equals the core. In this article, we compute the minimal conversely consistent extension of the men-optimal solution as a correspondence which associates with each problem the set consisting of the men-optimal matching, and all stable and men-barterproof matchings for this problem.     

Factors Affecting Choice and Satisfaction: Social Work in Turkey

ABSTRACT

The study examines the relationship between professional choices and employment expectations of social worker trainees in the country of Turkey. Professional choices are examined according to gender and the relationship between employment expectations and satisfaction. This study examined responses with a comparative relational scanning model with a sample of 692 social service (social worker) trainees studying at four different universities in Turkey. Students were surveyed and answered 25 open- and closed-ended questions identifying aspects related to their career choice. Study findings reveal that gender, university entrance scores, and employability were high among the career selection factors. Additional factors identified included family-related factors, personality traits, and compatibility. Examination of the findings is discussed, and recommendations for further research are made.     

Productive engagement across the life course: paid work and beyond

An uncertain economic outlook and the certitude of an ageing population highlight the importance of productive activity across all age groups for Australia's future. This paper reviews Australian and international research on productive ageing, which has typically focused on older age groups and specific activities, and presents national findings from Wave 10 (2010) of the Household, Income and Labour Dynamics in Australia (HILDA) Survey on productive activities across the life course. Both paid, tax‐generating and unpaid, voluntary activities are examined, including paid work, volunteering, caregiving, childcare, and domestic work. The kinds of productive activity people engaged in varied across age groups for men and women, highlighting the potential competition between paid work and other activities, and the importance of health and education for engagement across all ages. While the Government has begun leading actions to enhance and recognise these contributions that bring economic and social benefits both to the individual and the broader community, our research reinforces the value of investment in human capital for productive engagement across the lifespan inclusive of early, middle and later life.
