Pedagogical changes in curricula in higher education in Central Asia： A case study in psychology

This paper has three goals. First, to introduce a major pedagogical transition and discuss the challenges faced during the transition. Second, to provide a specific example of course changes that were required to meet this pedagogical transition and the challenges faced in adoption of new teaching techniques. The third goal of this paper is to provide faculty and universities with useful information to enhance their programs and meet the challenges faced during pedagogical transitions.     

Application of MALDI‐TOF MS for Estimating the Postmortem Interval in Rat Muscle Samples

Estimating the postmortem interval (PMI) is very important in the forensic sciences. Although many approaches have been used for estimating the PMI, accurate PMI calculations are still difficult. In this study, four Sprague Dawley (SD) rats were sacrificed by suffocation, and muscle samples were collected by dissection at various time intervals (0, 48, 96, and 144 h) after death. All samples were probed using matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI‐TOFMS) to obtain molecular images and data for principal component analysis (PCA). The results showed that the peaks at m/z 1511, 1543, 1564, 1586 clearly decreased in intensity from 0 to 144 h postmortem and that the time groups were separated from each other on the PCA score plot. The prediction model showed high recognition capability (95.93%) and cross‐validation (83.72%). Our work suggests that MALDI‐TOF MS can be used to determine the PMI.     

风险时代的秩序重建与法治信念——以“能动司法”为对象的讨论

转型时期中国社会呈现高风险状态。在民众中确立新的共同价值观和实现社会治理模式的规则之治是风险控制与秩序重建的两个基点。能动司法的出现回应了转型时期风险控制、秩序重建的需要,因而获得高度的政治合法性。能动应有之意包括:通过裁判确立风险社会的法治信念,重建社会共享价值体系;通过始终如一的适用法律,实现社会治理模式向规则之治转型;完善民众参与司法机制,让司法成为第一块公共领域。能动司法应当建立在对司法的本质属性与时代使命的准确把握基础上,在政治功能与审判职能之间保持必要的张力和平衡。     

能动司法哲学观的解读

司法能动主义首先是从美国兴起的一场司法运动。在历史上司法能动主义并没有一个统一的含义。在美国历史上就司法克制还是司法能动的争论非常激烈,而司法姿态也是在这两种审判哲学之间呈现出"来回摆动"的情形。随着我国法治建设的发展,这种争论也渗透到我国的司法界和理论界。目前我国提出能动司法的审判哲学,这与西方的司法能动主义存在交集,同时也有区别。对此,我们应该予以辩证地看待。     

Discrimination of Geographical Origin of Asian Garlic Using Isotopic and Chemical Datasets under Stepwise Principal Component Analysis

Isotopic compositions of δ²H, δ¹⁸O, δ¹³C, and δ¹⁵N and concentrations of 22 trace elements from garlic samples were analyzed and processed with stepwise principal component analysis (PCA) to discriminate garlic's country of origin among Asian regions including South Korea, Vietnam, Taiwan, and China. Results indicate that there is no single trace‐element concentration or isotopic composition that can accomplish the study's purpose and the stepwise PCA approach proposed does allow for discrimination between countries on a regional basis. Sequentially, Step‐1 PCA distinguishes garlic's country of origin among Taiwanese, South Korean, and Vietnamese samples; Step‐2 PCA discriminates Chinese garlic from South Korean garlic; and Step‐3 and Step‐4 PCA, Chinese garlic from Vietnamese garlic. In model tests, countries of origin of all audit samples were correctly discriminated by stepwise PCA. Consequently, this study demonstrates that stepwise PCA as applied is a simple and effective approach to discriminating country of origin among Asian garlics.

Classification and individualization of black ballpoint pen inks using principal component analysis of UV-vis absorption spectra

The technique of principal component analysis has been applied to the UV-vis spectra of inks obtained from a wide range of black ballpoint pens available in the UK market. Both the pen ink and material extracted from the ink line on paper have been examined. Here, principal component analysis characterised each spectrum within a group through the numerical loadings attached to the first few principal components. Analysis of the spectra from multiple measurements on the same brand of pen showed excellent reproducibility and clear discrimination between inks that was supported by statistical analysis. Indeed it was possible to discriminate between the pen ink and the ink line from all brands examined in this way, suggesting that the solvent extraction process may have an influence on these results. For the complete set of 25 pens, interpretation of the loadings for the first few principal components showed that both the pen inks and the extracted ink lines may be classified in an objective manner and in agreement with the results of parallel thin layer chromatography studies. Within each class almost all inks could be individualised. Further work has shown that principal component analysis may be used to identify a particular ink from a database of reference UV-vis spectra and a strategy for developing this approach is suggested.
