Evaluation of Mastoid Process as Sex Indicator in Modern White Americans using Geometric Morphometrics

Conventional methods for evaluating the mastoid as a sex indicator cannot determine whether mastoid shape is an independent and reliable sex indicator. Here, shape differences between the mastoids of 100 male and 100 female modern white Americans were statistically analyzed and visualized using the geometric morphometric method. Discriminant analysis was performed on mastoid size and shape. The relation between size and shape was analyzed to examine the effect of size on shape. In the results, mastoid size and shape were statistically significant sex indicators, while size factor explained 87.3% of the total variance of the shape variables. Nevertheless, females had relatively broader and shorter mastoid shape than males regardless of size, reflecting 12.7% of the total variance of the shape variables. In conclusion, mastoid size and shape were statistically significant sex indicators, while size may matter more in the mastoid than in other cranial parts in terms of sexual dimorphism.     

Does price really converge among provinces in Canada？ A study using unit root tests for cross-sectional panels

This paper examines price convergences across different provinces in Canada using 1983-2006 data. We adopt the new panel unit root tests for analysis that can correct for cross-sectional correlation. Our findings are contrary to previous studies and we conclude that intra-national price convergence does not occur. We also briefly discuss the reasons for the absence of convergence within Canada.     

On the Yogic Path to Enlightenment in Later Yogācāra

In later Yogācāra, the path to enlightenment is the course of learning the Four Noble Truths, investigating their meaning, and realizing them directly and experientially through meditative practice (bhāvanā). The object of the yogi’s enlightenment-realization is dharma and dharmin: The dharma is the true nature of real things, e.g., momentariness, while the dharmin is real things i.e., momentary things. During the practice of meditation, dharma is directly grasped in the process of clear manifestation (vi?adābhā) and the particular dharmin is indirectly ascertained in the process of determination (adhyavasāya). So, even though a yogi does not directly perceive any actual thing, s/he is still nonetheless able to undertake practical activity directed toward it. The realization of the Four Noble Truths consists of two aspects: firstly, the manifestation of momentariness, etc., in the stream of the yogi’s consciousness; secondly, the ascertainment of momentariness, etc., in whatever s/he happens to encounter.     

Determinants of citizen support for community-oriented policing

The extent to which community members are willing to cooperate with the police and become involved with various community crime prevention programs depends on citizen perceptions of the police and of the community in which they reside. The purpose of the present study is to explore factors that affect support for community policing in a small rural city. Findings revealed that the majority of respondents supported community policing. Using community survey data collected from over 400 citizens in a small metropolitan area in the intermountain West, this study also explored the importance of demographic factors, community characteristics, and public perceptions and experiences with police in predicting citizens’ support for community policing. Citizen support for community-oriented policing varied somewhat by demographic factors (i.e., gender, education), and by community characteristics (i.e., disorder, social cohesion).     

Determination and validation of tetrodotoxin in human whole blood using hydrophilic interaction liquid chromatography-tandem mass spectroscopy and its application

A sensitive analytical method was developed for the quantitative determination of tetrodotoxin (TTX), a powerful sodium channel blocker, in human postmortem whole blood. The sample mixture was cleaned up using cation exchange SPE catridge after protein precipitation by methanol and then separated on a PC-HILIC (phosphorylcholine hydrophilic interaction liquid chromatography) column (150 mm × 2.0mm i.d., 5 μm) using a isocratic elution of 1% acetic acid and acetonitrile. The identification of TTX was performed on tandem mass spectrometry with electrospray ionization interface in positive ion mode. The retention time of voglibose (internal standard) and TTX was 5.1 and 6.0 min, respectively. TTX and internal standard (voglibose) were monitored and quantitated using the ion transitions: the respective precursor to product ion combinations, m/z 320/302 for TTX and m/z 268/92 for voglibose in the multiple reaction monitoring (MRM) mode. The recovery of TTX and voglibose was 61.4% and 62.8%, respectively and the good accuracy (97.7-103.9%), linearity (2-1200 ng/mL) and reproducibility were shown in this method. The limit of detection and limit of quantification were 0.32 ng/mL and 1.08 ng/mL, respectively. This method was applied in the case of three fishermen who were poisoned (including one death) by unknown fish on their boat in October 2010. In this case, the levels of TTX were 27.2, 30.0 and 29.7 ng/mL in heart blood, peripheral blood and serum of a victim, were 3.1 and 12.1 ng/mL in peripheral blood and 3.9 and 12.8 ng/mL in serum of two survivors, respectively.     

mtDNAprofiler: A Web Application for the Nomenclature and Comparison of Human Mitochondrial DNA Sequences,

Mitochondrial DNA (mtDNA) is a valuable tool in the fields of forensic, population, and medical genetics. However, recording and comparing mtDNA control region or entire genome sequences would be difficult if researchers are not familiar with mtDNA nomenclature conventions. Therefore, mtDNAprofiler, a Web application, was designed for the analysis and comparison of mtDNA sequences in a string format or as a list of mtDNA single‐nucleotide polymorphisms (mtSNPs). mtDNAprofiler which comprises four mtDNA sequence‐analysis tools (mtDNA nomenclature, mtDNA assembly, mtSNP conversion, and mtSNP concordance‐check) supports not only the accurate analysis of mtDNA sequences via an automated nomenclature function, but also consistent management of mtSNP data via direct comparison and validity‐check functions. Since mtDNAprofiler consists of four tools that are associated with key steps of mtDNA sequence analysis, mtDNAprofiler will be helpful for researchers working with mtDNA. mtDNAprofiler is freely available at http://mtprofiler.yonsei.ac.kr .

人工智能与公共管理研究:技术可能性、议题重构和治理创新

人工智能对于人类社会的变革影响引起了公共管理领域的普遍重视,但在强人工智能以及人工智能必然导致自动化、智能化社会形态的前提假设下,相关研究可能继承了技术决定论的局限思维,从而低估了人工智能对于人类社会的潜在贡献。自然科学视角对于强人工智能的否定揭示了人工智能所具有的多种技术可能性,在此基础上从个体、组织、全球三个层面的议题重构更多强调人类自身以及人类社会活动的产物对于人工智能发展及其社会变革过程的影响,而由此启发学科、制度、政策三方面治理创新进而推动相关理论和实践以更为开放的态度面对新技术带来的变革与影响。
