Power,politics and policy in the appropriation of urban wetlands: the critical case of Sri Lanka

Little is known about the drivers and governance strategies of appropriation of urban nature in the global south. We compare urban land-grabbing in the city of Colombo, Sri Lanka, with broader understanding of rural land-grabbing in the developing world. We show that the colonial legacy of appropriation and alteration of urban wetlands in Colombo has attained new heights in the neo-liberal period. This cyclical process has caused acute irreversible damage to the wetland ecosystem and a vast majority of the urban poor, with the marginalised continuing to suffer dispossession and environmental hazard. In recognition of the inherent limitations of ‘uncontrollable’ hybrid ecologies, potent social struggles have emerged to resist the continued appropriation agenda. As this cycle is perpetuated, broader social struggles for democratic urban governance have overtaken the pursuit of narrow political-economic goals and internal policy reform.     

School and Neighborhood Contexts,Perceptions of Racial Discrimination,and Psychological Well-being Among African American Adolescents

The present study examined contextual influences on the relationship between racial discrimination (individual, cultural, and collective/institutional) and psychological well-being. Two hundred and fifty two African American adolescents (46% male and 54% female, average age = 16) completed measures of racial discrimination, self-esteem, depressive symptoms and life satisfaction. Archival information regarding the racial/ethnic composition of the participants’ neighborhoods and schools was used and increased school diversity was linked to increased perceptions of cultural discrimination. Regardless of school and neighborhood diversity, high perceptions of collective/institutional discrimination were linked to lower self-esteem for students in high diversity settings. Further, high levels of collective/institutional discrimination were associated with lower life satisfaction for African American youth in low diversity settings.

A “concrete” identification in a dismemberment case

Homicide perpetrators can use concrete as a means to conceal their victims. When concrete encasement is encountered in the forensic field, albeit rarely, it is often coupled with postmortem dismemberment. This method of obscuring the evidence presents unique investigative obstacles, specifically related to identification. Various approaches to obtaining fingerprints from decedents encased in concrete have been suggested and implemented over the years. The presented case is that of an initially unidentified 44-year-old male, who was subject to postmortem dismemberment and concrete encasement. Meticulous excavation techniques facilitated preservation of evidence and an anatomical reconstruction of the body. These techniques enabled inspection of the incision sites of the dismembered remains during the postmortem examination. Identifiable jewelry and tattoos were noted at autopsy. Further, the resulting concrete molds could be utilized to obtain fingerprints. These prints were used to ultimately identify the decedent.     

Optimization of the separation of organic explosives by capillary electrophoresis with artificial neural networks

The separation of 12 explosives by capillary electrophoresis was optimized with the aid of artificial neural networks (ANNs). The selectivity of the separation was manipulated by varying the concentration of sodium dodecyl sulfate (SDS) and the pH of the electrolyte, while maintaining the buffer concentration at 10 mM borate. The concentration of SDS and the electrolyte pH were used as input variables and the mobility of the explosives were used as output variables for the ANN. In total, eight experiments were performed based on a factorial design to train a variety of artificial neural network architectures. A further three experiments were required to train ANN architectures to adequately model the experimental space. A product resolution response surface was constructed based on the predicted mobilities of the best performing ANN. This response surface pointed to two optima; pH 9.0-9.1 and 60-65 mM SDS, and pH 8.4-8.6 and 50-60 mM SDS. Separation of all 12 explosives was achieved at the second optimum. The separation was further improved by changing the capillary to an extended cell detection window and reducing the diameter of the capillary from 75 microm to 50 microm. This provided a more efficient separation without compromising detection sensitivity.     

The use of pulmonary interstitial emphysema as an indicator of live birth

Making the determination of live birth versus stillbirth in a discarded newborn infant based on gross and microscopic autopsy findings can be a challenging task for the forensic pathologist. The traditional criteria for live birth determination are frequently challenged in court, and indisputable evidence of live birth remains elusive. The histologic finding of pulmonary interstitial emphysema has not been considered as a useful determinant of live birth. The authors report two cases of discarded newborn infants in which the finding of pulmonary interstitial emphysema was used as an indicator of live birth.     

Effects of self-concept and perceived disapproval of delinquent behavior in school children

It is argued that a multidimensional approach to self-concept may reveal intricate relations between self-concept and delinquent behavior, and that perceived approval of delinquent behaviors from referent groups may be related to the frequency of their occurrence. To evaluate these hypotheses, 1668 students from Grade 7 to Grade 9 responded to a questionnaire that measured their general self-esteem; their self-concept with regard to physical ability, social ability, physical appearance, and academic ability; the frequency they committed 15 delinquent acts; and the perceived approval of committing these acts from their parents, teachers, and friends. Regression analyses indicated that poor academic self-concept and poor relationship with school and parents were related to a higher frequency of delinquent behavior. However, a higher frequency of delinquent behavior was related to a more positive selfconcept with regard to social ability and physical ability. Finally, higher perceived approval from parents and peers was related to more delinquent behavior. Implications of these findings for identifying the antecedents and consequences of delinquent behavior were discussed.Received his Ph.D. from University of Illinois in social, industrial, and organizational psychology.

Pink‐Collar Representation and Budgetary Outcomes in US States

Legislatures worldwide are dominated by wealthy elites, who are often out of touch with the needs and problems of citizens. Research shows that the underrepresentation of the working class matters in terms of policy processes and outcomes. Yet the research on class has largely focused on blue‐collar representatives, who are primarily men. Working‐class women are more likely to hold pink‐collar jobs, or low‐status occupations dominated by women. We argue that pink‐collar legislators are uniquely positioned to legislate over education and social service policy. To test our argument, we combine a new coding of working‐class backgrounds that accounts for pink‐collar representation with state spending data on education and social services from US states over time. Modeling compositional budget data, we find that class and gender intersect to shape policy outcomes via state budget allocations, with women's pink‐collar representation associated with increased spending on both education and social services.
