Correlation of microscopic and mitochondrial DNA hair comparisons

Expert opinions regarding the microscopic comparison of human hairs have been accepted routinely in courts for decades. However, with the advent of mitochondrial DNA (mtDNA) sequencing, an assessment can be made of the association by microscopic hair comparisons in casework between a questioned hair and reference hairs from an individual. While each method can be used separately, the two analytical methods can be complementary and together can provide additional information regarding source association. Human hairs submitted to the FBI Laboratory for analysis between 1996 and 2000 were reviewed. Of 170 hair examinations, there were 80 microscopic associations; of these, only nine were excluded by mtDNA. Importantly, 66 hairs that were considered either unsuitable for microscopic examinations or yielded inconclusive microscopic associations provided mtDNA results. Only six hairs did not provide sufficient mtDNA, and only three yielded inconclusive results. Consistency was observed in exculpatory results with the two procedures. This study demonstrates the utility of microscopic hair examinations and the strength of combining microscopic analysis with mtDNA sequencing.     

At-risk factors for the adolescent mother and her infant

This article describes some at-risk features for the adolescent mother and her infant. The inadequacies of the adolescent mother may be manifest in her inability to provide for herself or her infant, and in difficulties in relating to a mate in a suitable fashion since she is still dependent on and, to some extent, symbiotic with her own mother. Complications, such as the increased possibility of having crises in pregnancy, a premature birth, giving up the baby for adoption, malnutrition, decreased stimulation, and divided mothering, are detailed. Compared to infants of adult mothers, offspring of adolescent mothers have a greater risk later on of conduct disorders, absence of both parents, and placement in foster homes or institutions. The adolescent mother's dynamics seem related to oedipal conflicts, wishes to mother and be mothered, and a predominance of symbiotic or other preoedipal conflicts. Becoming a mother in adolescence may be based on efforts to separate from infantile objects, an attempt to make up for the loss thereof, or substitution and avoidance of separation-individuation conflicts; or it might be an accident to avoid regression. At-risk factors are listed for the psychiatrist and pediatrician to observe in the adolescent mother and her infant in order to be alert to the possibilities of increased complications.Past President of American Society for Adolescent Psychiatry.

Factors associated with college crimes: Implications for campus police

A considerable amount of attention is now being paid to the serious nature of campus crime. However, little information is available with regard to those factors that might be closely associated with such incidents. This paper discusses security features and demographic characteristics of a select number of colleges throughout the country. It also describes the extent to which these factors are related to campus crimes. Conclusions and recommendations for campus police officials are discussed.

Psychosocial Factors in Adolescent and Young Adult Self-Reported Depressive Symptoms: Causal or Correlational Associations?

Using a large longitudinal representative community sample, this study identified three groups of subjects who were depressed either in pre-adolescence, late adolescence or early adulthood, and matched by age and gender to controls without depression. The 90th percentile on one or two self-reported symptom scales [i. e. the Center for Epidemilogical Studies Depression Scale (CES-D) or the subscale Anxious / Depressed subscale on either the Youth Self Report (YSR) or the Young Adult Self Report (YASR)] served as the cut-off for the depression groups. Psychosocial variables under study included life events and life events impact, coping, self-related cognitions, perceived parental rearing style, family relations, perceived school environment, and the internalizing (except anxious/depressed) and externalizing problem scale of the YSR/YASR. The study found a large number of time-related correlations between psychosocial factors and depression. Evidence for causal effect (either antecedent or consequent) was obtained only for self-esteem, perceived maternal rejection, and internalizing problems.     

Officer work orientations, perceptions of readiness and anticipated effectiveness of an agency-wide community policing effort within a county Sheriff’s office

Across occupations of every form, including those in criminal justice, administrators, managers, and supervisors frequently introduce changes to the structure and/or processes of the work environment. These changes may be seen as necessary to enhance worker productivity, but may be viewed by some workers as an unwanted disruption to their routines. Should employees interpret changes in such a manner, they can, and often do, negate these reforms. Employee work orientations (i.e., philosophical approaches toward work) undoubtedly play a role in such an interchange because they influence both how employees behave on the job and how they perceive their job. The move toward community-oriented policing constitutes a major paradigm shift to the practice of law enforcement. This structural and procedural change to the routines of policing could be perceived as threatening to those law enforcement officers whose work orientations are inconsistent with the philosophical foundation of community-based policing. The presence of a sufficient number of such officers could doom this movement to failure. This study uses survey data collected from a sample of sheriff’s deputies involved in an agency-wide community policing effort. In this study we examine the effects of deputies’ work orientations on their perceptions of the agency’s readiness for and the anticipated effectiveness of this initiative. The findings suggest interesting differences in the efforts of a traditional crime control orientation versus a more progressive community service orientation toward policing.
