Adult Learners and Credit for Prior Learning: Analytical Thinking and Motives
This study examined 364 adult learners using linguistic inquiry and word count (LIWC) of reflective writing assignments with implications for adult learners and educators and credit for prior learning (CPL)
A Decade of Prior Learning Assessment: A Systematic Review of Global Literature
Prior learning assessment (PLA) offers a powerful tool to adult learners. The purpose of this review was to systematically examine the global academic literature related to PLA over a decade
Prior learning assessment: Systematic review of academic literature
Many argue a college degree is more important than ever and required for many occupations. However, pursuing one requires time and money. Prior learning assessment (PLA) offers one solution to overcome such barriers by documenting outside learning through competency portfolios or assessment testing to receive academic credit. The purpose of this systematic literature review was to examine the academic literature related to PLA within the United States. The review searched 669 databases, across 72 disciplines/fields, and yielded 47 peer-reviewed journal articles, published in 14 journals, during the last decade. Findings included six major themes with implications for adult education theory and practice
Pan-cancer analysis reveals recurrent BCAR4 gene fusions across solid tumors
UNLABELLED: Chromosomal rearrangements often result in active regulatory regions juxtaposed upstream of an oncogene to generate an expressed gene fusion. Repeated activation of a common downstream partner-with differing upstream regions across a patient cohort-suggests a conserved oncogenic role. Analysis of 9,638 patients across 32 solid tumor types revealed an annotated long noncoding RNA (lncRNA), Breast Cancer Anti-Estrogen Resistance 4 (BCAR4), was the most prevalent, uncharacterized, downstream gene fusion partner occurring in 11 cancers. Its oncogenic role was confirmed using multiple cell lines with endogenous BCAR4 gene fusions. Furthermore, overexpressing clinically prevalent BCAR4 gene fusions in untransformed cell lines was sufficient to induce an oncogenic phenotype. We show that the minimum common region to all gene fusions harbors an open reading frame that is necessary to drive proliferation.
IMPLICATIONS: BCAR4 gene fusions represent an underappreciated class of gene fusions that may have biological and clinical implications across solid tumors
Restrictions impeding web-based courses: a survey of publishers' variation in authorising access to high quality on-line literature
BACKGROUND: Web-based delivery of educational programmes is becoming increasingly popular and is expected to expand, especially in medicine. The successful implementation of these programmes is reliant on their ability to provide access to web based materials, including high quality published work. Publishers' responses to requests to access health literature in the context of developing an electronic Master's degree course are described. METHODS: Two different permission requests were submitted to publishers. The first was to store an electronic version of a journal article, to which we subscribe, on a secure password protected server. The second was to reproduce extracts of published material on password protected web pages and CD Rom. RESULTS: Eight of 16 publishers were willing to grant permission to store electronic versions of articles without levying charges additional to the subscription. Twenty of 35 publishers gave permission to reproduce extracts of published work at no fee. Publishers' responses were highly variable to the requests for access to published material. This may be influenced by vague terminology within the 'fair dealing' provision in the copyright legislation, which seems to leave it open to individual interpretation. Considerable resource costs were incurred by the exercise. Time expended included those incurred by us: research to identify informed representatives within the publishing organisation, request 'chase-ups' and alternative examples being sought if publishers were uncooperative; and the publisher when dealing with numerous permission requests. Financial costs were also incurred by both parties through additional staffing and paperwork generated by the permission process, the latter including those purely borne by educators due to the necessary provision of photocopy 'course packs' when no suitably alternative material could be found if publishers were uncooperative. Finally we discuss the resultant bias in material towards readily available electronic resources as a result of publisher's uncooperative stance and encourage initiatives that aim to improve open electronic access. CONCLUSIONS: The permission request process has been expensive and has resulted in reduced access for students to the relevant literature. Variations in the responses from publishers suggest that for educational purposes common policies could be agreed and unnecessary restrictions removed in the future
Identification of an enhancer-like element upstream from a cell cycle dependent human H4 histone gene
We have identified a segment of DNA in the region 6,500 nucleotides upstream from a cell-cycle-dependent human H4 histone gene (pF0108A) which exhibits properties of an enhancer element. This distal element is not required for cap site initiation from the F0108A H4 histone gene. When the enhancer element is present in the genome as a stable integrated sequence, either in its natural upstream location or in a construct where the element is moved just upstream from the proximal promoter sequences, a 25-fold increase in the level of human H4 histone RNAs is observed. This increased level of mRNA reflects an increase in the rate of transcription. The enhancer effect is also observed when the distal element is inserted in inverse orientation with respect to this gene. In addition, the far upstream element can increase expression of a prokaryotic chloramphenicol acetyl transferase (CAT) gene under control of the simian virus 40 (SV40) early promotor, indicating that the ability to influence transcription is not confined to the gene with which it is normally associated. The ability of the histone gene distal enhancer element to function in both mouse and human cells indicates that transacting regulatory factors encoded by either the human or murine genome are capable of mediating the functional properties of this element, further supporting the cross-species compatibility of regulatory sequences and molecules that influence transcription of human histone genes
Challenges to early childhood education in rural China: lessons from the Hebei province
This research study examined the challenges faced by early childhood education (ECE) in rural China based on a qualitative study of 217 kindergarten classrooms in a large agricultural, rural province. This study utilised onsite teacher surveys, interviews, and observational field notes. This investigation’s findings revealed important information in regard to (a) enrollment, class size, and student-teacher ratios; (b) facilities, basic furnishings, and materials; (c) teacher qualifications; and (d) curriculum and pedagogy. Kindergartens in the rural province of Hebei, typical of Chinese provinces with economically disadvantaged students and inadequate ECE funding, were found to be of poor quality across every ECE indicator measured. For the future improvement and well-being of children and their families in rural China, the authors recommend reform policy to increase ECE quality by affiliating quality kindergartens with existing elementary public school structures and to improve teacher quality by advancing teacher benefits, professional status, and professional development opportunities
Effect of selective or combined inhibition of integrins alpha(IIb)beta(3) and alpha(v)beta(3) on thrombosis and neointima after oversized porcine coronary angioplasty
We conclude that both integrin alpha(IIb)beta(3) and integrin alpha(v)beta(3) participate in neointima development after experimental angioplasty
