Bidirectional Associations Between Valued Activities and Adolescent Positive Adjustment in a Longitudinal Study: Positive Mood as a Mediator

Although activity involvement has been linked to positive youth development, the value that adolescents place on these activities (i.e., how much they enjoy the activities, find them important, and spend time on them) has received less attention. The purpose of the present study was to examine the bidirectional longitudinal association between engagement in valued activities and adolescent positive adjustment (optimism, purpose in life, and self-esteem), as well as investigate a possible underlying mechanism for this link. High school students (N = 2,270, 48.7 % female) from Ontario, Canada completed questionnaires annually in grades 10, 11, and 12. Auto-regressive cross-lagged path analyses were conducted over time, controlling for gender, parental education, and academic grades. Greater engagement in valued activities predicted higher optimism, purpose, and self-esteem over time. Importantly, the results did not support an alternate hypothesis of selection effects, in that adolescents who were better adjusted were not more likely than their peers to engage in valued activities over time. We also found that the longitudinal associations between valued activities and positive adjustment may be due partly to an underlying effect of increased positive mood. Thus, engagement in valued activities appears to be important for adolescent positive adjustment, and may help to foster thriving. Communities, educators, and parents should actively support and encourage adolescents to develop valued activities, and seek to ensure that there are ample opportunities and resources available for them to do so.     

Understanding third‐party advertising: An analysis of the 2004, 2006 and 2008 Canadian elections

For approximately two decades, the federal regulation for third‐party election spending was the focus of repeated constitutional debate. However, with the 2004 Supreme Court decision in Harper v. Canada, a relative level of policy stability has been established. This stability permits us to evaluate the performance of spending limits according to the principles of the egalitarian model on which it is based. Using an original data set compiled from third‐party election advertising reports from the 2004, 2006 and 2008 federal elections, this article offers the first empirical analysis of this important election policy. A number of observations can be offered. First, third parties are not spending large amounts relative to spending limits. Second, despite legislative changes in 2006 banning all federal party contributions except those from individuals, there appears little strategic action by third parties in spending “around” contribution limits. During this three‐election cycle, third parties quite simply did not spend significant amounts. Current third‐party spending limits therefore appear to be situated comfortably within the expectations of the egalitarian model, though why third parties of all types spend so little remains in question.

Achievement of autonomy by nonhandicapped and mildly learning handicapped adolescents

This study examines the achievement of autonomy by a sample of 30 midly learning handicapped and 30 nonhandicapped adolescents. From participant observation over the course of a school year, a detailed account was obtained about the life of each subject, both in the home and among friends outside the home. Findings suggest that autonomy is achieved through a gradual process of negotiation during the high school years. The mildly handicapped adolescents generally lag behind their regular education counterparts in breaking away from the family. While almost three-fourths of the nonhandicapped sample had made significant gains toward increased freedom, less than half of the mildly handicapped sample had shed close supervision by parents. However, most of the handicapped adolescents were satisfied with the limited freedom they had. The data suggest that autonomy should be understood as relative to the needs and abilities of each individual. Not all adolescents develop at the same pace; not all feel the same desire to assert their independence from their parents when they reach a particular age.This research was supported by Grant HD23097 from the National Institute of Child Health and Human Development.Received his Ph.D. from the University of California, Irvine.

Current interest is social competence of mildly learning handicapped populations and family adjustment.     

The relative importance of identity status interview components

Eighty college males were given an expanded identity status interview which included two new interpersonal-sexual areas, “attitudes towards sexual expression” and “sex-role beliefs.” The relative contribution of the new content areas as well as of the standard three areas (occupation, religion, and politics) to overall identity status was assessed by noting the extent of correspondence. Identity status in each content area was also compared with performance on the dependent variable of cognitive complexity. Ideology contributed more than occupation both to overall status rating, as well as to discrimination on the dependent variable. Results on the two new areas supported the view that interpersonal-sexual concerns are important for men's identity development as well as for women's. The finding that all interview areas corresponded well with overall identity status and discriminated significantly on the dependent measure leads to the suggestion that the process variables of crisis and commitment may so overshadow a particular content area that any content of personal relevance for the late adolescent might be used in investigating ego identity development.     

Detection of ketosis in vitreous at autopsy after embalming

Ketosis occurs in ketoacidosis or malnourishment. When either is suspected in relation to a death, it may be important to analyze for ketosis at autopsy. We encountered a case where starvation was suspected in a deceased nursing home resident, where the body had been embalmed prior to autopsy. Gas chromatography (GC) was unable to separate acetone from formaldehyde, a component of embalming fluid. The Acetest is a simple test that can detect acetone and acetoacetate in body fluids. We validated the Acetest with GC on vitreous. The Acetest and GC were consistent except at very low levels of acetone or acetoacetate. The sensitivity of the Acetest for acetoacetate in vitreous was 10 mg/dL, consistent with early starvation. Significant interference from embalming fluid did not occur. The Acetest was negative in the described case. The Acetest is a simple and useful test for the detection of ketosis in embalmed autopsies.     

Sexual dimorphism in teeth: discriminatory effectiveness of permanent lower canine size observed in a XVIIIth century osteological series

Recent studies have shown that the most dimorphic tooth is the mandibular canine. We have carried out a study on a random sample of 146 skeletons dating from the plague outbreak in Marseilles (1722). We studied 1284 maxillary and 1432 mandibular permanent teeth. Sexual dimorphism was tested on 89 individuals. We selected a set of four dental indices and calculated the dimorphism percentage by ratio expression male/female. Dimorphic ranking was made, by allotting the first rank to the tooth presenting the highest dimorphism and the last rank to the one presenting the lowest ratio. Comparisons of means were made on both sexes (sex determined by post-cranial data) through a Student's test (t-test). We noted that lower canines and lateral incisor are the most interesting teeth in the dimorphic dental determination. The lower index presented the highest relative risk with RR = 1.56 [1.04-2.32]. In 58% of the cases, the lower dental index enabled a correct sex determination (determined on the basis of the post-cranial skeleton). These results showed the existence of a relative dental dimorphism (male > female mesiodistal diameters) with humans. In conclusion, this method, using dental measurements, may be used as an additional technique to determine sex on fragmentary adult skeletons, immature material, missing pieces or ambiguities on post-cranial remains.
