How Do I Feel About Feelings? Emotion Socialization in Families of Depressed and Healthy Adolescents

Emotional and cognitive changes that occur during adolescence set the stage for the development of adaptive or maladaptive beliefs about emotions. Although research suggests that parents’ behaviors and beliefs about emotions relate to children’s emotional abilities, few studies have looked at parental socialization of children’s emotions, particularly in families with depressed adolescents. The present study examined associations between parent and adolescent meta-emotion philosophies (MEP), defined as thoughts, reactions, and feelings about their own emotions. Additionally, adolescent depressive status was tested as a moderator of relationships between parents’ and adolescents’ MEP. One hundred and 52 adolescents, aged 14–18 (65.8% female), and their parents (148 mothers, 106 fathers) participated in a study on emotion socialization in families of depressed and healthy adolescents. Depressed adolescents (n = 75) and matched healthy adolescents (n = 77) were recruited based on research criteria for mental health status. The sample was largely Caucasian (82%) and of middle socioeconomic class status. Results indicated that mothers’ and fathers’ MEP about their children’s emotions were associated with adolescents’ MEP, although parents’ MEP about their own emotions was unrelated to adolescents’ MEP. Fathers’ MEP about children’s emotions made unique contributions to adolescents’ MEP across both adolescent groups. Adolescents’ depressive status moderated the relationship between mothers’ and adolescents’ MEP such that mothers’ MEP was particularly relevant for depressed adolescents. The continued influence of parents in the emotional lives of adolescents is discussed as well as differences in emotion socialization in families with depressed and healthy adolescents.     

The Military and SocietyBeyond the Postmodern Era

The degree to which the international security environment had changed after the Cold War became evident with the attacks on September 11. As a result, military forces in the United States (and perhaps in the West generally) are evolving from their Cold War and immediate post-Cold War perspectives to confront transnational and subnational non-state dangers. These changes have significant implications for military professionalism and the relations between the military and society. They are explored through a modified “Postmodern Military” model, called here the “Hybrid” model.     

Citizen perceptions of the legitimacy of traffic stops

Lundman and Kaufman (2003) reported that Black drivers were less likely than others to report that police made legitimate stops or that officers acted properly during traffic stops. The present work explored whether these results held when other variables were included in the model. Utilizing data drawn from a convenience sample, results show that being Black is not determinant in an expanded model aiming to better understand citizens’ perceptions of the legitimacy of traffic stops. Rather, size of place, time of day, and the race of the officer appeared to mediate the effect of “driving while Black”. Still, Black drivers had lower odds of reporting police acted properly during the traffic stop in either our basic or expanded model.     

Detection of sequence variation in the HVII region of the human mitochondrial genome in 689 individuals using immobilized sequence-specific oligonucleotide probes

We have developed a rapid, immobilized probe-based assay for the detection of sequence variation in the hypervariable segment II (HVII) of the mitochondrial DNA (mtDNA) control region. Using a panel of 17 sequence-specific oligonucleotide (SSO) probes immobilized on nylon membrane strips, we typed 689 individuals from four population groups. The genetic diversity value for each population was calculated from the frequency data, and the frequencies of distinct "mitotypes" in each group were determined. We performed DNA sequence analysis of 129 samples to characterize the sequences associated with "blanks" (absence of probe signals) and weak probe signals. Out of 689 samples, we observed five heteroplasmic samples (excluding the variable C-stretch beginning at position 303) using the immobilized SSO probe panel. The SSO probe strips were used for the analysis of shed hairs and bloodstains from several criminal cases in Sweden, one of which is described here. We conclude that this mtDNA typing system is useful for human identification and significantly decreases casework turnaround time.     

Hair analysis: self-reported use of "speed" and "ecstasy" compared with laboratory findings

Drug use histories were collected from 100 subjects recruited from the "dance scene" in and around Glasgow, Scotland. In addition, each subject donated a hair sample which was analyzed by gas chromatography/mass spectrometry (GC/MS) for amphetamine (AP), methamphetamine (MA), 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxymethamphetamine (MD MA) and 3,4-methylenedioxyethylamphetamine (MDEA). The hair samples were analyzed in two 6 cm segments or in full, ranging from 1.5 to 12 cm depending on the length of the hair. Approximately 10 mg of hair was ground to a fine powder before treatment with beta-glucuronidase/aryl sulfatase. A solid-phase extraction procedure was carried out followed by derivatization with pentafluoropropionic anhydride (PFPA). All extracts were analyzed by gas chromatography/mass spectrometry (GC/MS). Of the 139 segments analyzed, 77 (52.5%) were positive for at least one of the five amphetamines. The drug concentrations found in the hair were compared with the self-reported drug histories. A concordance of greater than 50% was found between the self-report data and levels detected in hair. However, no correlation was found between the reported number of "ecstasy" tablets consumed and the drug levels detected in hair. An increase in the average drug levels measured was observed from low to high use (number of "ecstasy" tablets/month). A large number of false negatives and a low number of false positives were observed.     

Quantitation of human genomic DNA through amplification of the amelogenin locus

An alternate method for quantitation of human genomic DNA is presented. Quantitative template amplification technology (abbreviated "Q-TAT") estimates the quantity of human DNA present in an extract by comparing fluorescence in X and Y amplicons produced from unknowns with fluorescence in a standard curve amplified from known quantities of reference DNA. Q-TAT utilizes PCR and electrophoresis with fluorescent detection/quantitation, precluding the need for new instrumentation, methodology, or quality assurance associated with slot-blot or real-time PCR. In a comparison study incorporating shared samples, Q-TAT was found to be more sensitive than widely used slot-blot methods but somewhat less sensitive than real-time PCR. Among samples containing DNA concentrations ranging from 100 pg/microL to 2-4 ng/microL, Q-TAT produced DNA concentration estimates that agreed reasonably well with either Quantiblot or real-time PCR. Q-TAT was reproducible with a typical coincidence of variation of about 35%. Quantitation of human DNA in this study involved summing fluorescence in X and Y amplicons in unknowns and quantitation standards. However, analyzing fluorescence in X and Y amplicons individually could allow estimates of male and female DNA present in mixtures to be made. Moreover, since X and Y amplicons exhibit sizes of 210 and 216 bp, respectively, the integrity as well as the concentration of the genomic DNA template can be assessed. Q-TAT represents an alternate method useful for the quantitation of human genomic DNA prior to amplification of STR loci used for identity testing purposes. The method uses existing equipment and procedures in conjunction with a well-characterized DNA standard to produce concentration estimates for unknowns that reliably produce STR profiles suitable for analysis.
