Evaluation of amylase testing as a tool for saliva screening of crime scene trace swabs

Amylase testing has been used as a presumptive test for crime scene saliva for over three decades, mainly to locate saliva stains on surfaces. We have developed a saliva screening application for crime scene trace swabs, utilising an amylase sensitive paper (Phadebas^® Forensic Press test). Positive results were obtained for all tested dried saliva stains (0.5–32 μL) with high or intermediate amylase activity (840 and 290 kU/L). Results were typically obtained within 5 min, and all samples that produced DNA profiles were positive. However, salivary amylase activities, as well as DNA concentrations, vary significantly between individuals. We show that there is no correlation between amylase activity and amount of DNA in fresh saliva. Even so, a positive amylase result indicates presence of saliva, and thereby presence of DNA. Amylase testing may be useful for screening in investigations where the number of DNA analyses is limited due to cost, e.g., in volume crime.     

Changing Balance: The Participation and Role of Voluntary Organisations in the Swedish Policy Process

This article focuses on the changing level of participation of voluntary organisations in the policy process between 1964 and 2009 and its implication for the role played by voluntary organisations to the state. Drawing on data from the remiss procedure – one of the most understudied parts of the Swedish policy‐making process – the results implicate a reduced role for voluntary organisations in formal arenas for policy making. While the number of participating voluntary organisations has remained stable, the relative share of participating organisations has declined and an increasing proportion of organisations have abstained from participating. In addition, the shares of conflict‐oriented and member‐benefit‐oriented organisations have decreased while consensus‐oriented and public‐benefit‐oriented organisations appear to have increased slightly. These findings are discussed in the context of changes in the coordination and implementation of public policies, implying that over time the role of voluntary organisations as arenas for deliberation and mediators of individual interests tend to have gradually lost ground in relation to the state while the share of organisations taking direct welfare responsibility has slightly increased. Although it may be premature to speak about a shifting role of voluntary organisations from input to output in the political system, the result suggest an emerging trend in that direction. Further research is needed to clarify whether this changing pattern of participation is evident in other arenas for policy making in Sweden or is an isolated feature explained from the outset of the remiss procedure.

The ecology of adolescent activity and experience

Twenty-five adolescents reported their daily activities and the quality of their experiences for a total of 753 times during a normal week, in response to random beeps transmitted by an electronic paging device. In this sample adolescents were found to spend most of their time either in conversation with peers or in watching television. Negative affects were prevalent in most activities involving socialization into adult roles. Television viewing appears to be an affectless state associated with deviant behavior and antisocial personality traits. The research suggests the importance of a systemic approach which studies persons' activities and experiences in an ecological context. The experiential sampling method described in this paper provides a tool for collecting such systemic data.The research reported herein was partially funded through PHS Grant 5-R01MH-22883-03.Received his Ph.D. from the University of Chicago.

The Korean ‘Examination Hell’: Long Hours of Studying,Distress, and Depression

The goal of this study was to investigate whether the higher rates of clinical depression found among Korean than American adolescents was related to Korean's daily ordeal of studying and schoolwork in preparation for the competitive college entrance examination. A sample of 56 high school seniors in Korea and 62 seniors in the United States provided time-sampling data on the amount of time they spent in daily activities and their affect states during these activities. The Korean adolescents were found to spend much more time in schoolwork and less time in discretionary activities than their American counterparts. Korean adolescents' affect states across daily activities were more negative relative to American adolescents. In the combined sample of Korean and American adolescents spending less time in active leisure activities and experiencing more negative affect states during schoolwork, socializing, and passive leisure activities were related to higher depression. These findings suggest that the effect of the college exam in generating depression in Korean adolescents may be partly mediated through its effect on their daily experience.     

Assessing the Electoral Connection: Evidence from the Early United States

Students of legislative behavior are divided over the extent to which an electoral connection existed in the early United States. In this article, we offer a test of the electoral connection in early American politics by investigating the electoral aftershocks of the disputed presidential election of 1824. Using newly available county-level presidential voting data, along with the unique circumstances associated with the presidential contest, we examine the connection between representative behavior, district public opinion, and electoral outcomes. We find that representatives who voted for John Quincy Adams in the House contest, yet were from districts supporting Andrew Jackson, were targeted for ouster and suffered a substantial vote-loss in the subsequent midterm election. We also find that the entry of a quality challenger had a sizeable impact on the fortunes of incumbent legislators. These results serve to confirm that representatives could be held accountable for their behavior in office during the antebellum era .
