Molecular Identification of Necrophagous Dermestes Species in South Korea Using Cytochrome c Oxidase Subunit I Nucleotide Sequences (Genus Dermestes)

Species identification of necrophagous insects found on a dead body is an essential key in applying medicolegal entomology to the estimation of postmortem interval (PMI). Due to limited morphological identification of insect evidence, several studies have identified species using molecular information such as DNA markers. While considerable cytochrome c oxidase subunit I (COI) gene sequence data of necrophagous fly species have been collected and annotated, those of necrophagous beetle species have not. Since necrophagous beetles such as Dermestes species have a larval period longer than that of flies, beetles are useful in even the late decomposition phase in estimating minimum PMI. To obtain the full-length COI gene sequences of six Dermestes species collected from South Korea, we designed primers for polymerase chain reaction amplification and sequencing. The obtained full COI nucleotide sequences were used for performing phylogenic analysis and comparison with previously reported sequences. The results demonstrated that the COI gene sequences could be used to identify forensically important Dermestes species in South Korea.     

Exploring Millennial Generation in Task Values and Sector Choice: A Case of Employment in Planning

This study investigates task values and motivations of “millennial” generation of planners and identifies important factors affecting their public sector choices. Multinomial logistic regression comparing the task values and specializations in private and nonprofit sectors with public sector was performed. Millennial generations in public sector value communication and implementation tasks where at young workers in private and nonprofit sector place importance on tasks related to administration and plan and policy development. The finding indicates private companies give favorable opportunities to the young workers to take leadership role in projects and appreciate their management skills to operate the programs and plans.

Strain,Negative Emotions,and Deviant Coping Among African Americans: A Test of General Strain Theory

Although previous research on Agnew's (1992) general strain theory (GST) tends to yield significant effects of strain on negative emotions as well as deviance and crime, results tend to be mixed with regard to (1) the effects of negative emotions on deviance and crime and (2) conditioning factors that Agnew suggests affect the selection of coping strategies. To address these issues, we test hypotheses, derived from GST, about the relationships among strain, negative emotions, and deviant coping by analyzing data from a nationally representative sample of African American adults. Ordinary least squares regression results generally support our hypotheses. First, fully mediating the effects of strain on deviant coping, negative emotions have consistently significant effects on deviance, regardless of whether we use composite or separate measures of inner- and outer-directed emotions and deviance. Interestingly, as hypothesized, the same-directed effects of negative emotions on deviant coping are larger than the opposite-directed ones. Second, while self-esteem and self-efficacy as conditioning factors generally fail to receive empirical support, religiosity is found to significantly buffer the effects of negative emotions on deviance. Implications of our findings for further development of GST are discussed.     

Allele frequencies of 10 STR loci in Koreans

Allele frequencies for the 10 STR loci, D6S1043, D9S925, D7S821, D4S2368, D21S2055, GATA193A07, D12S391, D10S2326, D15S822 and D18S51 were obtained from a sample of 217-310 unrelated Koreans. In this study, 2 out of the 10 loci did not meet Hardy-Weinberg expectation. The combined probability of identity for 10 loci tested was 4.93 x 10(-14).     

Nonprofit Service Continuity and Responses in the Pandemic: Disruptions,Ambiguity, Innovation,and Challenges

This Viewpoint essay examines the service delivery responses of nonprofit organizations that offer homeless support services amid the COVID-19 pandemic. Government mandates and severe human needs have forced nonprofits to adapt quickly. Literature reviews provide little information about how nonprofits should manage service continuity under pandemics. Data collected from websites and interviews with nonprofits executives provide an understanding of adaptations and innovations. The study uses a crisis response model—“Disruptions-Ambiguities-Innovations-Challenges” (DAIC)—to demonstrate how social service nonprofits are responding to challenges under COVID-19. Lessons learned are useful for scholars and practitioners to understand ways nonprofits have remained agile and innovative.     

Three Traditions of Network Research: What the Public Management Research Agenda Can Learn from Other Research Communities

This article identifies and describes the development of three parallel streams of literature about network theory and research: social network analysis, policy change and political science networks, and public management networks. Noting that these traditions have sometimes been inattentive to each other's work, the authors illustrate the similarities and differences in the underlying theoretical assumptions, types of research questions addressed, and research methods typically employed by the three traditions. The authors draw especially on the social network analysis (sociological) tradition to provide theoretical and research insights for those who focus primarily on public management networks. The article concludes with recommendations for advancing current scholarship on public management networks.     

Family Violence and Dating Violence in Korea

The purpose of this study is to examine the antecedents of dating violence. The paper hypothesizes that the relationship between family of origin violence and dating violence will be mediated by neutralizing beliefs. To test this hypothesis, a survey was conducted of 510 college students in Seoul and Kyung-gi provinces in South Korea. Partner violence and child abuse in the family of origin were associated with college students’ perpetration of dating violence. That relationship was mediated by neutralizing beliefs. The same results were found for both male and female students. Based on the findings, this study presents practical suggestions for intervening in dating violence.
