The Capability of Raman Microspectroscopy to Differentiate Printing Inks

This study applies Raman microspectroscopy to differentiate the chemical components in printing inks of different brands, colors, and type using the 532 nm and 785 nm excitation wavelengths. Spectra were collected from 319 inks (78 inkjet, 76 toner, 79 offset, and 86 intaglio) representing various colors. Comparisons were performed to calculate discrimination capability percentages for each ink type. Overall, Raman microspectroscopy differentiates according to the following hierarchy: intaglio (96%), inkjet (92%), offset (90%), and toner (61%). The ability of Raman microspectroscopy to differentiate between same‐colored inks from different brands was dependent on the color and ink analyzed. Based on ink color, the discrimination capability ranged from 75 to 94% (inkjet), 0 to 86% (toner), and 0 to 77% (offset). Copper phthalocyanine was detected in cyan inks and various intaglio inks, while carbon black was identified in black inkjet, offset, and intaglio inks.     

Curriculum Development for Public Sector Financial Management

Inadequate curriculum materials frequently impede the teaching of public sector financial management to graduate and mid-career students. The Curriculum Development Project at the School of Public Affairs of the University of Maryland has produced a draft curriculum that emphasizes the use of microcomputers and associated analytical skills in integrating topics in finance, accounting and budgeting.     

Migrant employment,recessions, and return migration: Some consequences for migration policy and development

After bringing approximately 13 million foreign migrants into Europe's industrial regions, the governments of many of these countries, among them France, Switzerland, West Germany, and the Netherlands have imposed severe restrictions on further immigration. Along with this move are the attempts by many countries to attract migrants back to their home countries. The recession of 1973 decreased the need for migrant labor and resulted in high levels of unemployment. The hard working migrant of the 1950's and 60's grew to become the politically active striker and social/political/financial burden on the state. Most governments have decided that future economic development will depend on technology, not labor production. The labor market structure of migrant workers helps explain why laid-off migrants do not return to their home countries. Political and economic conditions in the homeland also determine the amount of migrant return. The mere existence of a secondary labor force in an immigration country may make it easier to remain in that country. Incentives and financial inducements are needed to attract migrants home.     

The Resource Center for Separating and Divorcing Families: Interdisciplinary Perspectives on A Collaborative and Child‐Focused Approach to Alternative Dispute Resolution

The Resource Center for Separating and Divorcing Families (RCSDF) is a teaching model for providing interdisciplinary services to separating and divorcing families. The model was developed by the Honoring Families Initiative at the Institute for the Advancement of the American Legal System at the University of Denver. Services are provided by graduate and law students at the University of Denver, working side‐by‐side with a supervising licensed attorney, psychologist, and social worker. The experiential and interdisciplinary model of teaching and providing direct client services is the first of its kind in the United States. RCSDF students and staff seek to empower parents to make positive decisions about their family's future in a supportive and educational environment.

Key Points for the Family Court Community
• The current system of preparing graduate and law students for careers in family law is in need of improvement. This article provides information for educators and the family law community about the impact of interdisciplinary and experiential learning for students.
• Parents going through the transition of separation or divorce experience psychological and financial stressors that can create serious behavioral and adjustment issues for their children. The RCSDF works in a holistic manner with parents and children to minimize the levels of stress and anxiety during the transition.

     

A Quantitative Assessment of Zygomatic Projection for Ancestry Estimation

Anterior zygomatic projection (ZP) is historically referenced as a useful trait in ancestry estimation, particularly when differentiating between Native Americans and U.S. Whites and Blacks. However, methods of assessing ZP vary, are susceptible to multiple interpretations, and have not been quantitatively validated. This study uses 228 3D surface scans of U.S. Whites, U.S. Blacks, and Native Americans to quantitatively test the ZP methods published by Rhine in 1990 (Skeletal attribution of race: methods for forensic anthropology, Albuquerque, NM, Maxwell Museum of Anthropology, 1990) and Bass in 1995 (Human osteology: a laboratory and field manual, Columbia, MO: Missouri Archaeological Society, 1995). Two ZP angles and two distances, representing method interpretations, were collected and analyzed via ANOVA and discriminant function analyses. Although significant ancestry differences were found across all variables, only the Bass inferior zygomatic distance successfully differentiated the pooled Native American group from pooled U.S. Whites/Blacks (73.7% correct). Arctic Native Americans, displaying the most projecting zygomas, are driving group differences. Significant overlap in measurement distributions were observed between groups in all variables, indicating limited forensic utility.     

Inclusionary Housing After Koontz

Abstract

Inclusionary housing requirements, typically determined locally, have met with mixed success in the courts. After the U.S. Supreme Court's recent decision in Koontz v. St. Johns River Water Management District (Koontz), many are wondering if they have become harder to defend.     

Parents,Peers, Perceived Risk of Harm,and the Neighborhood: Contextualizing Key Influences on Adolescent Substance Use

Recent research has affirmed the need to examine contextual influences on adolescent substance use in a multilevel framework. This study examined the role of neighborhood opportunities for substance use in promoting adolescent substance use. Data came from two components of the Project on Human Development in Chicago Neighborhoods: the Longitudinal Cohort Study, consisting of interviews with youth and their primary caregivers across three waves of data with an average span of 4.5 years; and a Community Survey of neighborhood residents. Analysis used an Item-Response Theory-based statistical approach on 6556 substance use item responses from 1639 youth (49.0 % female) within 80 neighborhoods to assess the extent to which neighborhood opportunities for substance use had direct and indirect effects on adolescent substance use. Neither direct nor mediated effects of neighborhood opportunities for substance use on adolescent substance use were detected. But, analyses revealed moderating effects such that higher levels of neighborhood opportunities for substance use: (1) amplified the detrimental effects of parental substance use and peer substance use on youth substance use; and (2) attenuated the protective effect of adolescents’ perceived harm of substance use on adolescent substance use. The results suggest that the ways in which neighborhood characteristics impact adolescent behavior are nuanced. Rather than impact individual-level outcomes directly, neighborhood context may be particularly relevant by conditioning the effects of salient individual-level risk and protective factors for substance use.     

Paid Family Leave,Fathers’ Leave‐Taking,and Leave‐Sharing in Dual‐Earner Households

Using difference‐in‐difference and difference‐in‐difference‐in‐difference designs, we study California's Paid Family Leave (CA‐PFL) program, the first source of government‐provided paid parental leave available to fathers in the Unites States. Relative to the pre‐treatment mean, fathers of infants in California are 46 percent more likely to be on leave when CA‐PFL is available. In households where both parents work, we find suggestive evidence that CA‐PFL increases both father‐only leave‐taking (i.e., father on leave while mother is at work) and joint leave‐taking (i.e., both parents on leave at the same time). Effects are larger for fathers of first‐born children than for fathers of later‐born children.
