An Investigation of Personality Traits in Relation to Adolescent School Absenteeism

We examined the Big Five personality traits of Agreeableness, Conscientiousness, Emotional Stability, Extraversion, and Openness, as well as four narrower traits of Aggression, Optimism, Tough-Mindedness, and Work Drive in relation to absences from school for middle- and high-school students. Participants were 248 seventh grade students, 321 tenth grade students, and 282 twelfth grade students. Most of the Big Five absence correlations were significant in the expected direction at all 3 grade levels. While Aggression, Optimism, Work Drive were significantly related to absences, only Work Drive added incremental variance to the prediction of absences beyond the Big Five traits. Study results were generally similar across grade levels. Findings were discussed in terms of dispositional absenteeism, the generalizability of the Big Five trait model, and the utility of more narrowband traits. Implications were drawn for early identification of absence-prone students and the precedent role of personality variables in school absence research on the effects of other variables, programs, and interventions.     

The changing association between prenatal participation in WIC and birth outcomes in New York City.

We analyze the relationship between prenatal WIC participation and birth outcomes in New York City from 1988-2001. The analysis is unique for several reasons. First, we have over 800,000 births to women on Medicaid, the largest sample ever used to analyze prenatal participation in WIC. Second, we focus on measures of fetal growth distinct from preterm birth, since there is little clinical support for a link between nutritional supplementation and premature delivery. Third, we restrict the primary analysis to women on Medicaid who have no previous live births and who initiate prenatal care within the first four months of pregnancy. Our goal is to lessen heterogeneity between WIC and non-WIC participants by limiting the sample to highly motivated women who have no experience with WIC from a previous pregnancy. Fourth, we analyze a large sub-sample of twin deliveries. Multifetal pregnancies increase the risk of anemia and fetal growth retardation and thus may benefit more than singletons from nutritional supplementation. We find no relationship between prenatal WIC participation and measures of fetal growth among singletons. We find a modest pattern of association between WIC and fetal growth among U.S.-born Black twins. Our findings suggest that prenatal participation in WIC has had a minimal effect on adverse birth outcomes in New York City.     

PUBLIC POLICY AND INTERGOVERNMENTAL RELATIONS: TEACHER EDUCATION, 1960–1972*

Abstract: This is a case study of some aspects of teacher education policy formation in Australia. Between 1960 and 1972 the States sought to obtain from the national government specific purpose grant-aid for the training of their teachers, in addition to that already provided indirectly by grants to the States for their universities. The national government gave way, step-by-step, to this pressure, but “imposed” the broad condition of corporate “autonomy” for grant-aided tertiary educational institutions, instead of State departmental “control” of teacher training. The paper also considers what perspectives are suggested by this case study for the development of theories of public policy in the Australian federal system of government.     

Empowerment through group support: Adult women who are survivors of incest

This article describes the need for professional recognition of the magnitude of the problem of incest and the long-term effects on the lives of survivors. It suggests that women can be empowered to make positive lifestyle changes through long-term support. The educational opportunity provided for graduate students is also addressed. The intake process and the three phases of the group which extend over 56 sessions are described in detail.     

Compensation System Experience at 12 Months After Road or Workplace Injury in Victoria,Australia

Seeking or receiving compensation after injury is frequently associated with poor recovery. Previous research has shown that the stressful nature of compensation procedures and perceived injustice may cause secondary harm. This study examined compensation system experiences in compensation claimants in Victoria, Australia, and explored the relationship between these experiences and injury outcomes. One hundred and sixty compensable patients (120 male, 75.0 %) aged 18–67 years (M?=?43.01, SD?=?14.31), hospitalized for an injury in a motor vehicle crash (n?=?137) or at work (n?=?23), participated. Participants completed questionnaires about compensation system experience, pain, and psychological symptoms 12 months after injury. Principal component analysis (PCA) of the compensation system experience items revealed three components explaining 66.64 % of the variance in compensation experience: (1) “negative procedural experience” (47.29 %), (2) “compensation supported recovery” (10.43 %), and (3) “positive procedural experience” (8.92 %). Worse experience on all components was associated with worse pain (severity, interference, catastrophizing, disability) and psychological symptoms (anxiety, depression, PTSD, perceived injustice). Compensation system experience reflected both negative and positive procedural factors, and feeling supported through recovery. Most participants reported having positive experiences; however, those who were frustrated or stressed from compensation procedures had worse pain and psychological health outcomes. While this association is likely to be bidirectional with “non-recovery” also impacting on compensation experience appraisals, compensation schemes should nonetheless address modifiable sources of procedural injustice (e.g., arduous paperwork and approvals processes) and reinforce procedures that generate perceptions of support (e.g., timely and appropriate access to health services).     

The use of DNA stabilizing solution to enable room temperature storage and transportation of buccal and trace sample swabs

It is proposed that a DNA stabilizing solution (DNA Genotek Inc.) designed to preserve DNA in saliva samples at room temperature can be extrapolated to the storage of swab heads. The aim of this study was to evaluate the effectiveness of the solution for the preservation of reference swabs (buccal) and trace samples (facial swabs). To this end, the solution was used during a twin-site DNA transfer project assessing background levels of carer DNA present in children. Tubes containing 400 μl of solution were used to store and transport swab heads. At the laboratory, samples were extracted using the QIAamp DNA Mini Kit (Qiagen), quantified using the Quantifiler Duo Kit and profiled using the AmpF?STR^® SGM Plus^® PCR Amplification Kit (both Applied Biosystems). Twenty-eight PCR cycles were applied to all samples. Thirty-four cycles or a longer electrophoresis injection time was applied to trace samples where necessary. All Reference swabs produced high quantities of DNA and full DNA profiles after 28 cycles. Profile morphology indicated good quality DNA with no degradation. Of the trace samples, sufficient profiles were achieved to study the transfer of carer DNA making the solution fit for continued use in this project. DNA stabilizing solution enables the storage and transportation of swabs without freezing. This is convenient, reduces transportation costs and enables instant analysis of samples upon arrival at the laboratory. This is a useful alternative for a multi-site research project as well as a reliable storage tool for use in remote areas.     

Computer‐aided Dental Identification: An Objective Method for Assessment of Radiographic Image Similarity*

Abstract: A pilot study evaluated a computer‐based method for comparing digital dental images, utilizing a registration algorithm to correct for variations in projection geometry between images prior to a subtraction analysis. A numerical assessment of similarity was generated for pairs of images. Using well‐controlled laboratory settings, the method was evaluated as to its ability to identify the correct specimen with positive results. A subsequent clinical study examined longitudinal radiographic examinations of selected anatomical areas on 47 patients, analyzing the computer‐based method in making the correct identification based upon a threshold level of similarity. The results showed that at a threshold of 0.855, there were two false negative and two false positive identifications out of 957 analyses. Based on these initial findings, 25 dental records having two sets of full mouth series of radiographs were selected. The radiographs were digitized and grouped into six anatomical regions. The more recent set of films served as postmortem images. Each postmortem image was analyzed against all other images within the region. Images were registered to correct for differences in projection geometry prior to analysis. An area of interest was selected to assess image similarity. Analysis of variance was used to determine that there was a significant difference between images from the same individual and those from different individuals. Results showed that the threshold level of concordance will vary with the anatomical region of the mouth examined. This method may provide the most objective and reliable method for postmortem dental identification using intra‐oral images.
