Exploring Civic Engagement at an Urban Commuter Campus: Pathways and Barriers

Universities have traditionally had a vested interest in the civic preparation of students. In order to understand the unique situation of this population of students in a university serving non-traditional community students, qualitative data was used to identify pathways and barriers associated with their civic engagement. Results suggest themes associated with time, knowledge, and access.     

Lonelines in pre-through late adolescence: Exploring the contributions of a multidimensional approach

A multidimensional loneliness measure was administered to 444 subjects in the 11–17 age range. The four-scale instrument probes for loneliness in relationships with parents and peers, and for aversion to and affinity for aloneness. All subscales were shown to exhibit high reliability and excellent factorial validity. With regard to age effects, a marginally significant increase was found for parent-related loneliness, accompanied by a sudden drop at the seventh-grade level. A decreasing age trend emerged in both peer-related loneliness and aversion to aloneness. A set of variables pertaining to subjects' social integration (number of friends, quality of friendships) and psychological functioning (outlook on the future) accounted for a sizable portion of the variance in all four scales, particularly in peer-related loneliness. Implications of these findings are discussed and suggestions for future research are outlined.Portions of this paper were presented at the annual meeting of the Belgian Psychological Society, May 1985.Received his Ph.D. from that university in 1973. Current interests include loneliness in children and adolescents and life-span psychology.Current interests are cognitive development in adolescence and its concomitants in the social and personality realms.Current interests include adolescent loneliness.     

Personality Traits, Interpersonal Identity, and Relationship Stability: Longitudinal Linkages in Late Adolescence and Young Adulthood

Adolescence and young adulthood are characterized by important changes in personality, changes toward a more stable identity, and the establishment of intimate relationships. We examined the role of personality traits in establishing intimate relationships, the interplay between personality traits and interpersonal identity processes during these relationships, and the role of interpersonal identity processes and personality traits in the dissolution thereof. For this purpose, we used longitudinal data on 424 female college students (mean age at T1 = 18.6 years; Sample 1) and 390 late adolescents drawn from a community sample (56.7 % female; mean age at T1 = 19.7 years; Sample 2). Especially highly extraverted individuals were likely to become involved in a relationship. Neuroticism was associated negatively, and Agreeableness and Conscientiousness were associated positively with a stronger sense of interpersonal identity within intimate relationships. Finally, the importance of interpersonal identity processes was underscored by the fact that these processes, and not so much personality traits, predicted relational breakups. Overall, the present study provides important insights into the role of personality and identity in the initiation, maintenance, and dissolution of intimate relationships in late adolescence and young adulthood.     

Complex mixtures: A critical examination of a paper by Homer et al.

DNA evidence in criminal cases may be challenging to interpret if several individuals have contributed to a DNA-mixture. The genetic markers conventionally used for forensic applications may be insufficient to resolve cases where there is a small fraction of DNA (say less than 10%) from some contributors or where there are several (say more than 4) contributors. Recently methods have been proposed that claim to substantially improve on existing approaches [1]. The basic idea is to use high-density single nucleotide polymorphism (SNP) genotyping arrays including as many as 500,000 markers or more and explicitly exploit raw allele intensity measures. It is claimed that trace fractions of less than 0.1% can be reliably detected in mixtures with a large number of contributors. Specific forensic issues pertaining to the amount and quality of DNA are not discussed in the paper and will not be addressed here. Rather our paper critically examines the statistical methods and the validity of the conclusions drawn in Homer et al. (2008) [1].We provide a mathematical argument showing that the suggested statistical approach will give misleading results for important cases. For instance, for a two person mixture an individual contributing less than 33% is expected to be declared a non-contributor. The quoted threshold 33% applies when all relative allele frequencies are 0.5. Simulations confirmed the mathematical findings and also provide results for more complex cases. We specified several scenarios for the number of contributors, the mixing proportions and allele frequencies and simulated as many as 500,000 SNPs.A controlled, blinded experiment was performed using the Illumina GoldenGate^® 360 SNP test panel. Twenty-five mixtures were created from 2 to 5 contributors with proportions ranging from 0.01 to 0.99. The findings were consistent with the mathematical result and the simulations.We conclude that it is not possible to reliably infer the presence of minor contributors to mixtures following the approach suggested in Homer et al. (2008) [1]. The basic problem is that the method fails to account for mixing proportions.     

Local Government and Welfare Generosity: Municipality Spending on Social Welfare

Although it is difficult for local governments to give support for social welfare recipients top political priority, there are huge variations in the support recipients actually receive among Norwegian municipalities. However, local governments representing different party ideologies may prefer to support different dimensions of generosity. Some municipalities could have a liberal attitude to eligibility rules but be strict on time limits and the amount of money provided. Others may be generous regarding time limits or amounts received once one is accepted as a welfare client. Data from the mid 1990s indicate the variation in support is related to different generosity dimensions for different party groups. While the total number of clients seems unrelated to politics and basically correlates with local social problems, the duration and amount of support are related to the political composition of the municipality assembly. Devoid of any large variation, both time limits and the amount of support increase in accordance with socialist leanings, and the total budget used for social welfare support also increases with the proportion of women in the municipality assembly.     

Parenting,Effortful Control,and Adolescents’ Externalizing Problem Behavior: Moderation by Dopaminergic Genes

Research shows that genetics and effortful control play an important role in the link between parenting and problem behavior. However, little is known about how these factors act simultaneously. This article used a moderated mediation model to examine whether effortful control mediated the link between parenting and externalizing problem behavior, and whether dopaminergic genes (i.e., polygenic index score including DAT1, DRD2, DRD4, COMT) moderated this link. Two three-wave studies were conducted on community samples (adolescents: Study 1: N?=?457; M_age?=?15.74; Study 2: N?=?221; M_age?=?12.84). There was no mediation by effortful control, but a moderation by dopaminergic reactivity was observed. Despite inconsistent evidence, this article indicates that the development of externalizing problem behavior is subject to genetic characteristics and parenting.
