科学看待儿童读经

从时间、内容、方法和效果等四个维度认真剖析儿童读经现象,假若选择读经的时间适宜、经文思想性合乎当代中国的时代精神、经文难度系数得当、学生阅读方法科学,那么,适度让儿童读一些中国经典文章是一种妥当的教育方式,这样做既有利于中国优秀经典文化和中华传统美德在新时代的传承与发展,也有利于让儿童逐渐生成文化自觉意识和文化认同感,进而生成既与时代精神相对接又有中国文化根基的健全人格,还有利于儿童身心的"可持续性发展".

Validation studies of the ParaDNA® Intelligence System with artificial evidence items

Short tandem repeat (STR) profiling is one of the mostly used systems for forensic applications. In certain circumstances, STR profiling is time-consuming and costly, which potentially leads to delays in criminal investigations. LGC (Laboratory of the Government Chemist, UK) Forensics has developed a robust STR profiling platform called the ParaDNA^® Intelligence Test System which can provide early tactical intelligence and aid investigators in making informed decisions on sample prioritization for detection. Here, we validated the ParaDNA intelligence test for its application in forensic cases using a range of mock evidence items following guidelines set by the Scientific Working Group on DNA Analysis Methods (SWGDAM). Specifically, we tested the sensitivity and accuracy of the ParaDNA intelligence test, as well as the success rates for detecting mock samples and for use in case scenarios. Our findings demonstrate that the ParaDNA intelligence test generates useful DNA profiles, especially for samples such as blood, saliva, and semen that contain ample DNA, indicating the benefits of including ParaDNA as a prior step in forensic STR profiling pipelines.     

Touch DNA collection from improvised explosive devices: A comprehensive study of swabs and moistening agents

Improvised explosive devices (IEDs) are used in devastating terrorist attacks worldwide and daily in Thailand. Touch DNA deposited during IED assembly are subjected to intense heat and pressure, resulting in rare events of usable DNA profiles obtained from real casework. No study has simultaneously evaluated both swab brands and moistening agents for touch DNA collection from substrates encountered in IED evidence. In this study, we investigated the effects of swab brands and moistening agents on DNA collection from adhesive tape, a common IED substrate. A full factorial design using four cotton swab brands (two forensic and two medical cotton swabs) and six moistening agents (DNA-free water, phosphate-buffered saline, ethanol, sodium dodecyl sulfate, isopropanol, and lysis buffer) was employed (24 total combinations). Using buffy coats, we found that DNA recovery depended on both swab brands and moistening agents (p < 0.05). The optimal method recovered significantly higher DNA amount from real IED cases compared to the standard Royal Thai Police method. Percentages of high partial profiles also increased. Our results changed the standard operating protocol of the Thai police. Other commonly found substrates from IED cases are being investigated to maximize the evidential value obtained from touch DNA.     

Estimating Individual Contributions to Complex DNA SNP Mixtures.,

High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures.

Sustainability reporting by Australian local government authorities

This qualitative study investigates the Western Australian (WA) local government authorities’ sustainability reporting practices, in the absence of mandatory reporting guidelines, through content analysis of their websites. Calculations from comparing the Global Reporting Initiative (GRI)’s disclosures with those of 140 local council websites were used to develop a sustainability reporting disclosure index. The findings indicate that sustainability reporting remains moderately practised by local government authorities, despite stakeholder demand for proactive disclosures. The discourse analysis shows that Western Australia’s strategic planning for sustainable development is the key force propelling councils towards sustainability reporting practices. The findings also suggest that WA local government authorities are increasing sustainability disclosures to legitimate their social and environmental initiatives. The findings have policy implications for regulators and/or government in Western Australia, with practical implications for local council authorities and/or managers in developing awareness of sustainable operations. The study also contributes to local government authorities’ growing awareness of sustainable service operations.     

How Measurement Error in Content Analysis and Self-Reported Media Use Leads to Minimal Media Effect Findings in Linkage Analyses: A Simulation Study

In the debate on minimal media effects and their causes, methodological concerns about measurement are rarely discussed. We argue that even in state-of-the-art media-effects studies that combine measures of media messages and media use (i.e., linkage analyses), measurement error in both the media content analysis and the media use self-reports will typically lead to severely downward-biased effect estimates. We demonstrate this phenomenon using a large Monte Carlo simulation with varying parameters of the content analysis and the survey study. Results show that measurement error in the content analysis and media use variables does indeed lead to smaller effect estimates, especially when the media messages of interest are relatively rare. We discuss these findings as well as possible remedies and implications for future research.     

Understanding ‘The Panty Shanty’: off-campus house signs as cultural texts on gender and sexuality

Students at a large, prestigious, public university in the Midwestern region of the USA have a long-standing tradition of naming their rented houses off campus and communicating those names to the student body through displaying prominent and eye-catching house signs. Examples of signs names and visual characteristics are: ‘Betty Ford Clinic’ (featuring an image of a martini glass); ‘Morning Wood’ (referencing male sexual arousal and depicting a tent with a man's legs sticking out); ‘Time Well Wasted’ (written in pink over a beach scene and a martini glass); ‘Fox Den’ (images of a fox tail and a well-known sorority symbol); ‘Tequila Mockingbird’ (a play on words); and ‘Down on U’ (the sign references a sexual act for a house located on University Avenue). Through a socio-feminist and social constructionist perspective, the researchers use content analysis to explore how these house signs serve as cultural texts on gender and sexuality norms in the American undergraduate college setting. Based on our data, house signs reinforce dominant forms of gender ideologies, including hegemonic masculinity and emphasized femininity, both of which are associated with upholding and promoting institutionalized patriarchy (Connell, R. W., &; Messerschmidt, J. W. (2005 Connell, R. W., &; Messerschmidt, J. W. (2005). Hegemonic masculinity: Rethinking the concept. Gender &; Society, 19, 829–859. 10.1177/0891243205278639.[Crossref], [Web of Science ®] , [Google Scholar]). Hegemonic masculinity: Rethinking the concept. Gender &; Society, 19, 829–859). These house signs are also shown through the data to promote a campus culture of heteronormativity where partying, drinking, and casual sex are standards for social belonging, and where high rates of sexual assault persist. As opposed to viewing house signs as simply manifestations of student wit and harmless humor, the researchers critically evaluate if and how these visual displays serve as a mechanism through which gender and sexuality-related inequalities are perpetuated within a higher education institutional setting. Implications for students and their college campuses are discussed.
