Exploitation of the Ultraviolet Properties and Machine Cut Edges of Paper to Associate and Sequence Sheets in a Ream

Previously unreported line patterns visible under ultraviolet light were observed on a proportion of plain white A4 printer/copier paper from different manufacturers. These Ultraviolet Line Patterns (UVLPs) usually appear as stripes down the vertical length of the paper. Typically, the UVLPs were found to “repeat” through the ream in a predictable way, while also changing. It is postulated that the repeating nature of the UVLPs is a result of the way that paper is manufactured. This leads to the ability to sequence the sheets compared to their original source paper. Even in the absence of UVLPs, it is possible to use our observation of the manufacturing process to anticipate the order of several sheets of paper and conclusively associate them, in some cases, by physically fitting their machine cut edges and crossing paper fibers. Such a novel approach to examining questioned documents would be highly useful in forensic casework.

Responding to academic dishonesty in universities: a restorative justice approach

The implementation of restorative approaches in schools has been commonly seen in elementary and high schools, yet the development of restorative approaches in post‐secondary institutions has not been fully explored. In respect to university education, a more restorative approach to student discipline can be a proactive educational response mediating the response of student discipline boards to instances of student wrongdoing. Existing practices are explored, and critiqued from a restorative justice perspective. The rationale behind moving to a restorative response is outlined, and the experiences of student discipline boards that currently employ restorative approaches are assessed to determine how effective this paradigm shift could be. How university responses to student misconduct might function if aspects of the academic environment were built on restorative values and principles is explored, in particular, through looking at the benefits accruing to the development of restorative practices in the classroom, in distance education and for students who experience language difficulties.

The Effect of Intergenerational Conflict and School-Based Racial Discrimination on Depression and Academic Achievement in Filipino American Adolescents

Abstract

Bronfenbrenner's ecological model postulates the home and school to be key microsystems in fostering emotional well-being and school functioning in children. Utilizing a sample of 663 Filipino American adolescents who participated in the Children of Immigrants Longitudinal Study (CILS), we assessed the effect of intergenerational conflict at home and racial discrimination at school on their mental health and academic achievement. Cross-sectionally, intergenerational conflict and school-based racial discrimination increased depression and decreased academic achievement in early adolescence. Longitudinally, conflict and discrimination in early adolescence decreased academic performance while conflict alone increased depression in late adolescence. Implications of the findings were discussed.     

Torture and terrorism: an interview with Moazzam Begg

This article presents some of the findings of research on issues surrounding teaching terrorism and political violence at UK higher education institutions. It reports the results of a survey of UK institutions of higher education on their responses to government and other pressures in relation to terrorism. The data show a minority of universities have developed systems, policies or procedures for ‘preventing violent extremism’, while a significant number have developed close cooperation and collaboration with state counterterrorism policies raising potential issues of academic freedom. This article then examines three high-profile cases – incidents where universities, lecturers and students have come under political and legal pressures over the content of terrorism courses or accusations of ‘radicalisation’ on campus. It suggests that these pressures can be and sometimes are resisted, but that they have on occasion effectively narrowed the scope of academic freedom in practise with the danger that a further chilling effect follows in their wake.     

Two Ecological Models of Academic Achievement Among Diverse Students With and Without Disabilities in Transition

School experiences can have positive effects on student academic achievement, yet less is known about intermediary processes that contribute to these positive effects. We examined pathways between school experiences and academic achievement among 117 low-income urban students of color, many with disabilities, who transitioned to other schools following a school closure. Using structural equation modeling, we tested two ecological models that examined the relationships among self-reported school experiences, school support, academic self-efficacy, and school-reported academic achievement. The model in which the relationship between school experiences and academic achievement is mediated by both school support and academic self-efficacy, and that takes previous academic achievement into account, was an excellent fit with the data. The roles of contextual and individual factors as they relate to academic achievement, and the implications of these findings, are discussed.     

论提升学术期刊核心竞争力

新形势对学术期刊的生存发展能力提出了更高的要求,应对挑战的必然选择是提升学术期刊的核心竞争力。有必要对核心竞争力的概念和特征进行新的解读,围绕影响核心竞争力提升的主要因素,从"理念铸魂、内容为王、人才是本、管理有道、创新至上"五个方面进行思考。     

学术论文中的学术失范、学术不端现象及其防范

目前辨别及防范学术失范和学术不端行为已成为学术期刊出版的一项重要工作。选取某学术期刊,对其来稿情况及利用《学术不端行为检测系统》比对的结果进行分析。结果表明,作者来稿中的学术失范和学术不端行为的产生既有主观原因又有客观因素,涉及到作者的学术态度、写作动机,对学术道德的认识,对引文标注、著作权法等相关规范和法律条文的理解,以及对网络媒体和纸质期刊之间关系的了解等各个方面。学术期刊的编辑,是学术论文发表的审核者和把关者,应该利用好《学术不端行为检测系统》,辩证地分析检测结果,提高辨别和防范学术失范及学术不端行为的能力,尽最大可能避免重复发表和剽窃之作流向社会。
