Single Nucleotide Polymorphism Assay for Genetic Identification of Lophophora williamsii*

Lophophora is a member of the Cactaceae family, which contains two species: Lophophora williamsii and L. diffusa. Lophophora williamsii is an illegal plant containing mescaline, a hallucinogenic alkaloid. In this study, a novel method based on a single nucleotide polymorphism (SNP) assay was developed for identifying L. williamsii; this assay reliably detects SNPs within chloroplast DNA (rbcL, matK, and trnL-trnF IGS) and was validated for identifying Lophophora and L. williamsii simultaneously. The chloroplast DNA sequences from four L. williamsii and three L. diffusa plants were obtained and compared using DNA sequence data from approximately 300 other Cactaceae species available in GenBank. From this sequence data, a total of seven SNPs were determined to be suitable for identifying L. williamsii. A multiplex assay was constructed using the ABI PRISM^® SNaPshot™ Multiplex Kit (Applied Biosystems, Forster City, CA) to analyze species-specific SNPs. Using this multiplex assay, we clearly distinguished the Lophophora among 19 species in the Cactaceae family. Additionally, L. williamsii was distinguished from L. diffusa. These results suggest that the newly developed assay may help resolve crimes related to illegal distribution and use. This multiplex assay will be useful for the genetic identification of L. williamsii and can complement conventional methods of detecting mescaline.     

Pete Maravich's incredible heart

Postmortem examination of a former professional basketball player revealed an abnormal heart, most notably a single coronary artery. The literature on single coronary arteries is briefly reviewed, and the possible mechanism which caused the patient's condition is considered. This case is particularly unusual because of the patient's profession, which is so physically demanding.     

Scales for perceived risk of student-on-student victimization in grades 7 through 10: A psychometric analysis of the adolescent index on school safety

Although past research has developed scales for the incidence, prevalence, and fear of student-on-student victimization (SSV), little is known about the scaling of perceived risk (i.e., the cognitive appraisal of the chances of experiencing SSV). Hence, this study examined self-report survey data for the perceived risk of SSV as measured in the Adolescent Index for School Safety (AISS). Children in grades 7 through 10 (n=337) in a single Florida public school completed the AISS. Factor analyses using Maximum Likelihood Estimation with Oblimin Rotation identified nine unique factors for perceived risk. Reliability analyses found standardized Cronbach Alphas that ranged from .64 to .91, and seven out of the nine identified scales were above .80, which suggested good to excellent internal consistency. Future research should examine the content validity, construct validity, and predictive validity for the AISS and other self-report surveys of SSV dynamics.

Explicating Acculturation Strategies among Asian American Youth: Subtypes and Correlates across Filipino and Korean Americans

Acculturation strategy, a varying combination of heritage and mainstream cultural orientations and one of the significant determinants of youth development, has been understudied with Asian American youth and particularly at a subgroup-specific level. This study used person-oriented latent profile analysis (LPA) to identify acculturation strategy subtypes among Filipino American and Korean American adolescents living in the Midwest. Associations between the subtypes and numerous correlates including demographics, family process and youth outcomes were also examined. Using large scale survey data (N?=?1580; 379 Filipino American youth and 377 parents, and 410 Korean American youth and 414 parents; M_AGE of youth?=?15.01), the study found three acculturation subtypes for Filipino American youth: High Assimilation with Ethnic Identity, Integrated Bicultural with Strongest Ethnic Identity, and Modest Bicultural with Strong Ethnic Identity; and three acculturation subtypes for Korean American youth: Separation, Integrated Bicultural, and Modest Bicultural with Strong Ethnic Identity. Both Filipino American and Korean American youth exhibited immersion in the host culture while retaining a strong heritage identity. Although bicultural strategies appear most favorable, the results varied by gender and ethnicity, e.g., integrated bicultural Filipino Americans, comprised of more girls, might do well at school but were at risk of poor mental health. Korean American separation, comprised of more boys, demonstrated a small but significant risk in family process and substance use behaviors that merits in-depth examination. The findings deepen the understanding of heterogeneous acculturation strategies among Asian American youth and provide implications for future research.     

The Politics of Central Tax Collection in China since 1994: local collusion and political control

The central leaders in China adopted a tax assignment system and centralized taxation in 1994 with the goal of increasing central tax revenues. By setting up the National Tax Bureau, the central leaders intended to leave central tax collection undisturbed by local influences. However, informal practices at the local level revealed that the local governments colluded with the central tax bureaucrats stationed in their regions at the expense of central interests. The need to develop local economies, an important task assigned to local governments, is one important reason behind local interference in central tax collection. This study finds that the central government coped with this problem by changing the incentives of the provincial party secretaries through linking central tax collection in a jurisdiction with their chance of promotion.     

Lessons from a crisis: An analysis of Toyota's handling of the recall crisis

The purpose of this study is to evaluate how Toyota managed the recall crisis through surveying public relations experts. By gathering and analyzing the perspectives of public relations (PR) executives and professors toward the Toyota recall crisis, this study tries to evaluate and measure Toyota's public relations strategies for managing the recall crisis. To collecting data, 34 public relations professors and 92 public relations practitioners were interviewed. According to the findings of this study, PR professionals emphasized that Toyota responded poorly (slowly/dishonestly) and lacked communication with the public. With regard to improvements Toyota may work on, PR experts advised not only to resolve internal corporate problems but also to strengthen the relationships with consumers and obligation to investigate further. In regarding with the lessons from the Toyota's crisis, PR professionals highlighted that it is necessary to take anticipated preventative measures and improve investigative duties and preparation for better dealing with crises.     

Korea in the post-cold War Era

As mentioned earlier, the Korean peninsula remains unfortunately one of the last vestiges of the Cold War. And it is essentially up to the 70 million Korean people in the South and the North to wash away the undesirable legacies of the old regimes, to institute a solid structure of peace and stability on their land, and to lay the foundation for unification. And this task must be achieved at the latest by the end of this century. A new order is now emerging in East Asia. The unification of Korea is essential for this new order to evolve. To this end, the Republic of Korea will exert every effort to reach modus vivendi with the North at the earliest time and to put into effect the agreements and commitments made at the conference table. The resolution of the nuclear issue is of utmost importance in creating an environment in which both sides will be able to deal with each other with reasonable mutual trust and confidence.     

Factors Associated with Physician Discussion of Health Behaviors with Adolescents

Behaviors developed in adolescence influence health later in life. The purpose of this study was to investigate the frequency of health care provider's discussion of health behaviors with overweight and non-overweight adolescents and identify demographic and health behaviors related to exercise, hours of television viewing, and weight issues associated with these discussions. A Cross sectional survey of urban adolescents was conducted. Trained interviewers administered surveys over a three month period in 2001 at an urban academic pediatric and adolescent clinic. The 252 adolescents surveyed had a mean age of 15 with 49% categorized as being at risk for overweight/overweight and 51% as normal weight using the CDC percentiles for BMI. While 16% of the adolescents reported that their physician or nurse discussed the amount of television they watched, rates of discussion related to exercise (58%), and weight (54%) were much higher. In multivariate analyses, health care provider discussions with adolescents regarding exercise were more common for overweight (O.R.=2.42, 95% C.I. [1.28–4.57]) and at risk for overweight (O.R.=1.98, 95% C.I. [1.03–3.81]) adolescents, whereas physician discussion of television viewing was not associated with weight. Discussions of weight were more common for female (O.R.=2.18, 95% C.I. [1.21–3.95]), African-American (O.R.=2.53, 95% C.I. [1.40–4.57]), and overweight (O.R.=3.92, 95% C.I. [1.97–7.81]) adolescents. Even after adjusting for weight, race and gender strongly influenced the frequency of discussions about weight in physician offices. Although health care providers frequently address weight and exercise with adolescents, more discussions related to sedentary behaviors such as television viewing may be warranted to address adolescent obesity.Received PhD in Epidemiology from University of California, San Diego.

The statistical variability of blood alcohol concentration measurements in drink-driving cases

Like many other places in the world, Hong Kong has drink-driving legislation which prohibits a driver from having in his blood alcohol exceeding a prescribed limit while in control of a motor vehicle. The accuracy of measuring this alcohol concentration is obviously of prime concern as an erroneous result can avert the administration of justice. The common practice is to deduct all errors from the measured value and compare the deducted value with the prescribed limit, so that the benefit of all errors of the measurement is given to the driver. It is therefore important for any laboratory responsible for measuring blood alcohol concentrations to identify and quantify all errors associated with the measurement. The present study examined 900 blood alcohol determinations carried out by the Hong Kong Government Laboratory (HKGL) on cases of suspected drink driving. The determinations were performed by 5 different analysts with two different sets of instruments during 1995-1997. Statistical analysis indicated that the instruments had no bearing on the random error or variability and that even though analyst was a significant factor on variability, the deviation from the mean so caused was only 0.3% and of no practical significance. When the systematic error introduced by the tolerance limits of the certified alcohol standards (purchased from the Laboratory of Government Chemists, UK) was taken into account, the total uncertainty (random plus systematic errors) of an alcohol determination at 99.5% confidence level was found to be 4%. It is recommended that laboratories engaged in blood alcohol determination should adopt similar statistical treatment of their analytical results to find out the error and to ensure that the results are independent of analyst and instrument used.
