This paper addresses the problem of using traffic counts to ascertain zonal trip generation characteristics when performing quick-response travel forecasts. A family of origin–destination (O-D) trip table estimation methods containing three unexplored members (biproportional, uniproportional, and dynamic biproportional) is proposed to solve this problem. The family is tested on static planning networks for Tallahassee, Florida; Northfield, Minnesota; and Fredericton, New Brunswick, Canada. Results indicate that travel forecasting models can be made to match ground counts better by a simple factoring of origins, destinations, or both. The three methods that directly solve for origin or destination factors have computational and statistical advantages over full-matrix O-D trip table estimation procedures, and the results are qualitatively and quantitatively interpretable.

The aim of this study was to compare forgiveness in secure and insecure Iranian married couples. Whether marriage had occurred within the family (consanguine) or not (non-consanguine) was also considered. 400 married participants completed the Family Forgiveness Scale and the Adult Attachment Questionnaire. Analysis of reported forgiveness within the marital family showed that, although there was no significant difference between secure and insecure participants in overall forgiveness, secure participants rated “reparation” and “resolution” higher, whereas insecure participants rated “realization” and “recognition” higher. Comparing the experience of forgiveness in the family of origin, securely attached couples not only reported significantly more overall forgiveness but reported more “realization” and “resolution” while forgiving. Some interesting sex differences were also found, as individuals in consanguine vs non-consanguine couples differed in mean “recognition” in the forgiveness process.

Based on a developmental contextual perspective advocated by Vondracek, Lerner, and Schulenberg, this article provides a comprehensive review of the research published since 1980related to family of origin influences on career developmentandoccupational choice. Because individuals are most likely to seek assistance with career decisions from family members, it is important that counseling psychologists understand how families can have a positive influence and facilitate career development. Influential family contextual factors are identified within four developmentallevels (i.e., children, adolescents, college students/young adults, and adults). Across the lifespan, both family structure variables (e.g., parents’ occupations) and family process variables (e.g., warmth, support, attachment, autonomy) were found to influence a host of career constructs; however, the process by which families influence career development is complex and is affected by many contextual factors such as race, gender, and age. Based on this comprehensivereview, implicationsfor counselingresearch andpracticeare discussed.

The paper investigates whether, in what way and to what extent the family of origin affects offspring’s poverty risk in selected EU countriesrepresenting different social protection systems. Employing logit models and utilizing EU-SILC data, the analysis brings to the forefront the importance of social protection for intercepting the intergenerational transmission of poverty. Denmark with the socialdemocratic welfare state is the most successful in mitigating the effect of the family of origin on offspring’s poverty risk, followed by France representing the conservative-corporatist welfare regime. Less effective οn this matter appear to be Greece and Great Britain representing the south-European and the liberal social protection system respectively.
