Analysis and discrimination of architectural paint samples via a population study

This study involved the comparative analysis and discrimination of 964 architectural paint samples collected in the United States and Canada. The samples were evaluated to determine the extent to which randomly collected architectural finishes can be discriminated following standard operating protocols for paint analysis. The study also provides a basis for assessing the significance of a result in which a pair or group are undifferentiated. The techniques utilized were stereomicroscopy, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) with both backscatter electron imaging (BSI) and energy dispersive spectroscopy (EDS), and pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). To assess the layer characteristics (e.g., number, color, sequence, thickness), stereomicroscopy was used with FTIR and/or SEM as needed. The use of visual and microscopic evaluations in concert with FTIR resulted in 42 undifferentiated pairs, a discrimination of 99.99%. Adding SEM and Py-GC/MS analysis resulted in further discrimination of 31 pairs, resulting in eleven undiscriminated pairs of samples. At the conclusion of the study, samples that remained undifferentiated proved to originate from the same source. Therefore, no random pairs were indistinguishable at the conclusion of all examinations.     

Analysis and discrimination of electrical tapes: Part I. Adhesives

This study involved the comparative analysis and discrimination of 90 electrical tape adhesives. The objectives included the evaluation of the ability of individual techniques to discriminate samples and the assessment of the ability of the techniques combined to distinguish samples. The techniques utilized were stereomicroscopy, Fourier transform infrared spectroscopy (FTIR), pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), and scanning electron microscopy/energy dispersive spectroscopy (SEM/EDS). Stereomicroscopy, to assess adhesive colors of black, clear/colorless, and clear adhesives with brown tint, resulted in a discrimination of 53%. FTIR analysis yielded eight distinct groups with a discrimination of 67%. Py-GC/MS analysis resulted in 16 groups with a discrimination of 83%. These analyses confirmed and further subdivided the FTIR groups. SEM/EDS resulted in five separate groups at 17% discrimination, increasing the overall discrimination to above 85%.     

HUNTER‐GATHERER COLLABORATIVE PRACTICE

This article describes the development of a practice group based on a hunter‐gatherer model, with the mission of providing high quality collaborative divorce services, with an emphasis on protecting children and divorcing partners, and expanding access to middle‐ and lower‐income families. The practice group professional disciplines include law, mental health divorce coaching, co‐parent coaching, financial analysis, and case administration. These professionals have collectively associated their individual practices to address challenges facing their collaborative practices. With common purpose, the practice group builds skills, generates client base, nurtures trust, and lays a common knowledge base. Collaborative divorce teams formed from its members serve divorcing families with efficient, cost‐conscious, interest‐based negotiation processes that protect children and help parties productively move on with their lives.     

Intoxication Levels of Bar Patrons at an Organized Pub Crawl in a College Campus Community

This field study examined whether participants of a traditional, end-of-semester pub crawl in a college campus community had higher levels of intoxication than non-participating bar patrons on the same night as the event. A total of 693 bar patrons participated in the study. Anonymous interview and breath alcohol concentration (BrAC) data were collected from pedestrians in a bar district at the end point of the pub crawl route between 10:00 p.m. and 3:00 a.m. on the night of the event during three different semesters (November, 2007, May, 2008, and May, 2009). A multivariate model adjusting for participant demographics and drinking variables showed that participation in the pub crawl was associated with a 70% reduced risk of being highly intoxicated (i.e., BrAC ≥ 0.08 g/210 L). The lower intoxication levels among pub crawl participants may have implications for harm reduction practices at high-risk drinking events. These implications are discussed.     

Compassion as a Political Virtue

The place of compassion in political thought and practice is debatable. This debate can be clarified by stipulating 'compassion' as referring to the practice of acting on the feeling of 'pity'; in addition, compassion might best be understood politically speaking as properly exercised towards vulnerability rather than suffering . Working with these understandings, I contrast Martha Nussbaum's account of the criteria for the exercise of compassion in modern democracies with the treatment of compassion in Toni Morrison's novels in order to suggest how compassion can be viewed politically. In respect of distributive justice and public policy, in both cases compassion might modify the strict application of principles in the light of knowledge of particulars, suggesting an enlarged role for discretion in the implementation of social justice. More generally, compassion's focus on particulars and the interpersonal draws attention to the importance of imagination and judgement. The latter returns a consideration of compassion to the question of the relationship of compassion to justice. In the political context, although strict criteria for compassion are inappropriate, principles of justice might work as modifying compassion (rather than vice-versa, as might be expected).     

Patterns of physical and sexual abuse for men and women in dating relationships: A descriptive analysis

A random sample of students at a large Midwestern University was selected in order to examine whether and how physical and sexual abuse were related to each other for men and women, whether abuse in one relationship was independent of abuse in other relationships, and how victims responded to abusive incidents. The results revealed several important patterns. When comparing the frequency of physical and sexual abuse for men and women, it was found that sexual abuse was more common than physical abuse, but only for women. Additionally, women experienced more sexual abuse than men. While men and women did not experience physical abuse in other relationships at more than chance levels, women who sustained sexual abuse in one relationship were more likely to sustain sexual abuse in other relationships. Furthermore, while sustaining physical and sexual abuse were not associated with one another for men, there was a weak association for women. Finally, victims of abuse were more likely to tell their friends they had been abused than report it to criminal justice authorities.Paper presented at the 1987 American Society of Criminology Meetings.     

The Impact of Objective and Empathic Dispositions on Local Government Budget Analysts' Spending Preferences

The spending preferences of local government budget analysts are based on individual decision modes; how individuals attend to, encode, and process information. While academicians and practitioners tend to assume that a budget analyst's disposition to act leads to specific spending preferences, that assumption is rarely tested empirically. This study draws on two theoretical constructs derived from social psychology, rationality (objectivism), and emotions (empathy). Leary and his colleagues demonstrate that objectivism predisposes one toward rational decision making in a variety of settings, while Eisenberg and her colleagues show that highly empathic individuals are predisposed toward helping and prosocial behavior. Results of this study suggests that empathic budget analysts, those scoring higher on the empathy scale, have distinctly different spending preferences than those budget analysts scoring higher on the objectivism scale; empathic budget analysts are disposed toward humanitarian criteria in decision making while objective budget analysts are disposed toward quantifiable cost-benefit considerations.
