The Contraceptive Self-Efficacy Scale: Analysis in Four Samples

Previous research has established a relationship between Contraceptive Self-Efficacy (CSE), as measured by the 18-item CSE scale, and young women's contraceptive behavior (Bilodeau, Forget, and Tetreault, 1994; Heinrich, 1993; Levinson, 1986; Wright, 1992). In this paper, we continue to explore the scale and its relationship to contraceptive behavior with four diverse samples to establish generalizability and to set guidelines for use of the scale. A series of correlational analyses were conducted with each sample. A pattern of low correlations among CSE items across samples emerged, indicating that use of the total item set separately as the basis for CSE was warranted. Zero-order and partial correlations revealed which CSE items were correlated with contraceptive behavior as well as which items explained unique variance in contraceptive behavior for each sample. Regression analyses showed that CSE was significantly predictive of contraceptive behavior for all samples. These results are discussed in terms of scale properties and use in research and clinical settings. Educational implications are formulated as well.     

Fighting the Korean War in pacifist Japan: Korean and Japanese leftist solidarity and American Cold War containment

Where does “pacifist” Japan fit within the history of the Korean War? Was Japan simply the beneficiary of the wartime boom – a case best exemplified by Japanese Prime Minister Yoshida Shigeru’s characterization of the Korean War as “a gift of the gods”? When North Korean troops crossed the thirty-eighth parallel and launched a full-scale attack against South Korea, the U.S. occupation in Japan quickly transformed the pacifist nation into the indispensable rear base of United Nations military intervention in the Korean War. The Japanese Communist Party and leftist groups organized by zainichi Koreans (Korean residents in Japan) launched an antiwar movement to stop Japan from producing and sending arms to UN forces in Korea. The U.S. occupation responded with determined efforts to contain every antiwar voice emerging from the streets of the pacifist country. By examining the political dynamics of zainichi Korean and Japanese leftist solidarity and U.S. countermeasures, this article shows how the Korean War was fought in pacifist Japan. It also illuminates how the practice of Cold War containment was mutually linked on the ground between occupied Japan and South Korea.     

Distribution of methamphetamine and amphetamine in drug abusers’ head hair

In order to aid the interpretation of hair results from methamphetamine (MA) abusers the MA and amphetamine (AP) concentrations in 2070 hair samples were statistically evaluated. The MA and AP concentrations in hair were put into three groups arbitrarily representing low, medium and high ranges and the metabolite-to-parent drug ratios of each group were examined. The concentration ranges proposed here were also applied to the interpretation of five authentic cases. The low, medium and high ranges of MA were 0.5–4.2, 4.2–24.5 and 24.5–608.9 ng/mg and those of AP were 0.1–0.4, 0.4–1.7 and 1.7–41.4 ng/mg. The AP-to-MA ratios showed large variation but a tendency that it decreased as the MA ranges increased. This evaluation was very useful to presume the severity of individuals’ MA abuse and to provide law enforcement agencies more understandable information. It could also facilitate the court's decision regarding specific circumstances surrounding the drug-related crimes.     

Metal-containing nanoparticles and nano-structured particles in fingermark detection

This article reviews the application of metal-containing nanoparticles and nano-structured particles to fingermark detection. This area of research is attracting significant interest as advances in nanoscience are being incorporated into the field of forensic fingermark detection. Although more research is needed before some of the techniques presented can be implemented in routine casework, nanotechnology is likely to play a major role in the future to deliver more selective and more sensitive ways to detect and enhance fingermarks.     

Success Factors for Transferring Technology to Spin-off Applications: the Case of The Technology Property Rights Concession Program in Korea

This paper is a study of 127 firms participating in Korea's Technology Property Rights Concession Program, a program designed to stimulate technology transfer related to spin-off applications of public technology. The purpose is to identify the determinants of transfer success. The findings indicate that successful firms were motivated by the ability to access a core technology free of charge and to solve technical problems currently encountered in technology development. Second, the targeted technology was highly reliable. Third, interest in commercial success of the transfer was very high among the researchers involved in the transfer process and these researchers had a high degree of prior understanding about industrial problems on the part of participating firms. Relatedly, there was a very high satisfaction with the communication that existed between lab researchers and their industrial partners in the transfer process. Fourth, lab contributions to the transfer process were very high in the pre-commercial and commercial stages of technology development.     

Multiple Identification and Risks: Examination of Peer Factors Across Multiracial and Single-Race Youth

Multiracial youth are thought to be more vulnerable to peer-related risk factors than are single-race youth. However, there have been surprisingly few well-designed studies on this topic. This study empirically investigated the extent to which multiracial youth are at higher risk for peer influenced problem behavior. Data are from a representative and longitudinal sample of youth from Washington State (N?=?1,760, mean age?=?14.13, 50.9% girls). Of those in the sample, 225 youth self-identified as multiracial (12.8%), 1,259 as White (71.5%), 152 as Latino (8.6%), and 124 as Asian American (7.1%). Results show that multiracial youth have higher rates of violence and alcohol use than Whites and more marijuana use than Asian Americans. Higher levels of socioeconomic disadvantage and single-parent family status partly explained the higher rates of problem behaviors among multiracial youth. Peer risk factors of substance-using or antisocial friends were higher for multiracial youth than Whites, even after socioeconomic variables were accounted for, demonstrating a higher rate of peer risks among multiracial youth. The number of substance-using friends was the most consistently significant correlate and predictor of problems and was highest among multiracial youth. However, interaction tests did not provide consistent evidence of a stronger influence of peer risks among multiracial youth. Findings underscore the importance of a differentiated understanding of vulnerability in order to better target prevention and intervention efforts as well as the need for further research that can help identify and explain the unique experiences and vulnerabilities of multiracial youth.     

Home and the materialization of the divergent subjectivities of older women in Hong Kong

Although the social status of women in Hong Kong has changed significantly in recent decades, Hong Kong women continue to perform mothering, caregiving and homemaking tasks into late adulthood. Employing an agential realist approach to analyse the homes and discursive–materialist practices of three older women, this paper explores how the entanglement of materialities, discourses and subjectivities at home as a site of cultural action contributes to the ongoing enactment of divergent subjectivities of older Hong Kong women. The structural–spatial configurations of the three homes manifest the patrilineal and male-dominated family system in Hong Kong, and such older women perform a set of ‘normal’ (house) wifely and motherly duties linked to the maintenance of the male-dominated family system. Nevertheless, these older women’s subjectivities and their domestic worlds evolve through ongoing discursive–materialist practices. This paper further argues that, even if such factors as materialities, structures and practices either are neutral or indeed reinforce existing power imbalances, the dynamic and ongoing intra-action of these factors results in exclusionary but open conditions that may stabilize or subvert social phenomena, such as the ones discussed in this study: patriarchal domestic practices in Hong Kong homes.     

Examining the Links Between General Strain and Control Theories: an Investigation of Delinquency in South Korea

In modifying general strain theory (GST), Agnew has accepted the control-related variables as conditioning variables to moderate or mediate the casual process through strain into delinquency. In this regard, this study aims to empirically and theoretically address the void of connecting traditional and redefined self-control variables to GST. To explore this issue, the current study employed data derived from the Korea Children and Youth Panel Study (KCYPS). Specifically, three waves (2012, 2013, and 2014) were used to test hypotheses from GST and control theories. Both trait-based low self-control and revised self-control partially mediated the relationship between strain and delinquency. However, only redefined self-control significantly interacted with strain in producing delinquency. The current research reveals the possible integration of redefined control theory and GST.

     

Cross-examination of liquid-liquid extraction (LLE) and solid-phase microextraction (SPME) methods for impurity profiling of methamphetamine

Impurities in 48 methamphetamine (MA) samples were analyzed by liquid-liquid extraction (LLE) and headspace solid-phase microextraction (HS-SPME) methods. MPS-2 autosampler was used to improve reproducibility of SPME method, and nonadecane (C(19)) diluted with potassium bromide (KBr) powder was used as an internal standard for standardizing retention time. Impurities identified by SPME method showed different patterns compared with LLE method. Non-volatile impurities like methamphetamine dimer were not identified by SPME method, but some volatile impurities like diphenylketone, caprolactam and lots of unknowns were identified only by SPME method. 1-Phenyl-2-propanone (P2P), 1-phenyl-2-propanol and benzylcyanide peaks could be discriminated clearly by SPME method without interference of amphetamine, an artifact originates from MA degradation. Differences in the impurity patterns resulted in different clustering results. When 48 MA samples were classified into 5 LLE and 5 SPME clusters, cross-matching of the clusters resulted in 8 sub-clusters. It shows that combination of the different extraction methods can distinguish the differences which cannot be distinguished by LLE or SPME method alone, and can improve reliability of the profiling results.     

Collaborative Partnerships and Crime in Disorganized Communities

Collaborative partnerships can be an effective strategy for crime prevention, especially in disorganized communities. Using ordinary least squares regression with 414 American cities, this article finds that police departments with many collaborative partnerships are able to promote informal social control within their communities and capitalize on the resources available to them with the help of other groups. This contention is supported by the effects of collaborative partnerships on crime rates in disorganized communities in comparison to well‐organized communities. Thus, collaborative partnerships of public organizations with other groups may insulate disorganized communities from the effects of community disorganization on levels of crime.
