Hybrid open access journals generally authorize self-archiving along with Author-pays model. Given the dependence of the Author-pays model on APCs paid by authors, it is expected to have a negative association with the free-of-charge Green model. By exploring a sample of 52,150 papers published in 47 Elsevier's hybrid journals, the study compares the OA models' citation performances to non-open access (NOA) model's and investigates the relationship between the quantities of their papers.Three OA groups are identified, including Green-only, APC-only and Green-APC. The OA papers show a citation advantage over the NOA articles, despite their lower number. The mixed APC-Green, gains the highest citation compared to the three other access models. However, the number of Green and APC-funded papers are revealed to have a negative association. Although, the combination of the Green and APC models magnifies the impact of OA papers, the inverse association between the quantities of their papers signifies that the lower number of the latter can be partially explained by the prevalence of the former. The results help academic librarians involved in advocating and managing OA to better understand authors' behaviors towards OA models and adopt a more supportive role for OA according to their preferences. 相似文献

α-Thalassemia (α-thal) is considered as the most common inherited hemoglobin disorder worldwide. The present study describes the first observation of a combination of rare α-chain variants, and β-globin gene cluster deletion. A 21-year-old woman with thalassemia trait, marked microcytosis, mild anemia, and normal range of Hb F was referred to Amirkola genetic center in the North of Iran for routine molecular test of thalassemia in the context of carrier detection and prevention of thalassemia major birth. Nucleotide sequencing revealed a novel compound heterozygosity status for two non-deletional mutations on HBA2, Hb O Indonesia (α116(GH4)Glu → Lys), and Hb Matsue–Oki (α75 (EF4) Asp → Asn), together with heterozygosity for the sicilian (δβ)0-thal mutation. This finding highlights the necessity of deep molecular investigation of thalassemia in regions where thalassemia is abundant, and present highly heterogeneous population. 相似文献

Information system success has been widely discussed in the past two decades. As systems and technologies are being improved and developed, discussions on their effectiveness and evaluation on their success have been continuously debated by researchers, scholars and practitioners throughout the years. Besides the major concern of IS effectiveness, factors influencing IS effectiveness are also important. One of these factors is the organizational factor. Using perceptual measures, this study aims to investigate the influence of organizational factors on MIS success. Survey questionnaires were gathered from 132 Extension Managers from Iran's Agricultural Extension Providers. Seven items were identified to influence MIS success. They are IS department structure, top management support, management style, managerial IT knowledge, goal alignment, resources allocation and IS infrastructure. The study also identified five MIS success dimensions; systems quality, information quality, perceived Ease of use, organizational impact and individual impact. The study found that the MIS success variables are significantly and highly correlated. The study also found all the organizational factors are significantly correlated to the five IS success factors investigated; the system quality, information quality, perceived ease of use, organizational impact and individual impact. Multiple regression analyses also found goal alignment as the highest predictor of IS success, followed by IS department structure, IS infrastructure and management style. 相似文献

Disaster Management (DM) is a diffused area of knowledge. It has many complex features interconnecting the physical and the social views of the world. Many international and national bodies create knowledge models to allow knowledge sharing and effective DM activities. But these are often narrow in focus and deal with specified disaster types. We analyze thirty such models to uncover that many DM activities are actually common even when the events vary. We then create a unified view of DM in the form of a metamodel. We apply a metamodelling process to ensure that this metamodel is complete and consistent. We validate it and present a representational layer to unify and share knowledge as well as combine and match different DM activities according to different disaster situations. 相似文献

England has experienced recent growth in the prevalence of private tutoring (PT). The qualitative study reported in this article aims to explore the perceptions of 14 Year 6 pupils and their teachers from three state-maintained primary schools in East Kent on PT participation and its impact on grammar school admissions. Data were collected through individual and focus group interviews and pupils' drawings. The data revealed that teachers were not totally aware of the scale of PT in their classes and ascribed PT merely to parental decision to prepare their child to pass the 11-plus, grammar school entrance test. However, some pupils indicated that they shared in the decision to have PT, affirming that it was not only for 11-plus test familiarisation and practice. PT also contributed to greater pupil confidence, involvement and enthusiasm for learning, together with improvement in social interactive skills (i.e. intangible benefits). Both teachers and pupils also explained the disadvantages of PT, including the psychological and financial burdens on the whole family and changing the playing field level. Teachers proposed some solutions to help Year 6 pupils without PT. From this qualitative study, pedagogical implications as well as areas for ongoing research are suggested. 相似文献

ABSTRACT This research paper aims to examine the effects of extracurricular activities in building knowledge, skills and attitudes that attempt to develop ecological citizenship as a subset of global citizenship among middle school students. I focus on one extracurricular programme entitled ‘The Friends of Nature’ that was provided in a Moroccan private middle school. Adopting a qualitative research method approach, data consisted of interviews with thirty students from 7th, 8th and 9th grades and two teachers (social studies and life and earth science teacher), and were collected over the course of three months through multiple data collection tools, namely observation, student focus group discussions and teacher interviews. A series of environmental activities offered students opportunities to: identify environmental problems, promote education for sustainable development and improve their environmentally conscious behaviour, develop creative solutions, and take actions for preserving nature in their community. The data were analysed using a content analysis method. The results reveal that students demonstrated cognitive development in terms of human rights, citizenship rights and responsibilities, environmental sustainability. While the program developed attitudes of empathy, respect, solidarity, it failed to instil a sense of responsibility to act for the betterment of the world, thus being a global citizen. 相似文献
