Previous reports stressed on the importance of international collaboration and open access (OA) publishing, as they increase the quality of the research and increase its benefits. In this study, we will assess Jordanian international research collaboration and OA publishing in the past 10 years. We performed a Scopus search for Jordanian publications in the years 2008–2017, where we extracted and calculated the total number of publications, publications in OA journals, publications with international collaborations. Moreover, we assessed the disciplines Jordanians usually publish in. During the 10-year interval, we found a total of 20,359 Jordan-affiliated publications indexed in Scopus. We found a dramatic increase in number of publications with international collaboration from 38% in 2008 reaching 53.3% in 2017, and an increase in OA publications from 7.3% of the total publications in 2008, reaching 18.7% of the total publications in 2017. Total number of Scopus indexed publications from Jordan has increased by 57.9% over the past 10 years. Although international collaboration and OA publications have dramatically increased in recent years, Jordanian researchers should focus more on international collaboration with developed countries and on self-archiving their publications. 相似文献

Date pits for feed preparation or oil extraction are soaked in water to soften before milling or extrusion. Knowledge of water absorption by the date pits helps in better managing the soaking duration. In this research, the process of water absorption by date pits was modeled and analyzed using Fick's second law of diffusion, finite element approach, and Peleg model. The moisture content of the pits reached to its saturation level of 41.5% (wet basis) after 10 d. The estimated coefficient of diffusion was 9.89×10-12 m2/s. The finite element model with a proposed ellipsoid geometry for a single date pit and the analytical model fitted better to the experimental data with R2 of 0.98. The former model slightly overestimated the moisture content of the pits during the initial stages of the soaking and the latter model generally underestimated this variable through the entire stages of soaking process. 相似文献

The purpose of the present study is to document, compare, and analyze the nature of spatial reasoning by practitioners (plumbers)
in the workplace and students in the school setting while constructing solids, with given specifications, from plane surfaces.
Data were collected from a plumbing workshop and five high school students while constructing a cylindrical container of capacity
one-liter and height of 20 cm. The results confirm the power of activity theory and its methodology in explaining and identifying
the structural differences between the two activities in the two different cultural settings. Students and plumber activity
structures differed in the operational aspect (actions) and the means and concrete conditions (operations) under which such
a goal is carried out. Activity theory has the potential to explain the differences between the two activities in terms of
differences in the motive, social-cultural settings, the tools that were available and accessible which resulted in different
actions, and the constraints (operations) under which the task was executed. Theoretical and pedagogical implications were
identified.

Members of a knowledge translation and exchange (KTE) research team assessed the training needs of the teaching staff at a school for individuals with intellectual/developmental disabilities (IDD). In response to this need, KTE researchers retrieved peer‐reviewed articles for training staff working with individuals with IDD who exhibit challenging behaviours. These articles were categorised according to the following training content: (1) interventions designed to reduce the frequency of challenging behaviours; (2) appropriate ways to manage challenging behaviours in the moment to promote safety for all parties and/or to terminate the ongoing behaviour; and/or (3) procedures or perspectives relevant to coping with or ameliorating the negative impacts of challenging behaviours on staff. We then examined the training methods (teaching strategies, training duration) involved in teaching the content and assessed the effectiveness of these programmes. Overall, we found that effective training programmes consisted of workshops, practica and feedback on specific skill performance. Some forms of brief training were effective for increasing staffs' knowledge/skills and reducing the frequency of challenging behaviour. 相似文献

In this study we explored the effect of podcasting on the motivation of the students in an online English for Academic Purposes (EAP) course at the university level (N?=?179). By using a mixed-method approach, we analyzed the data collected on the learners' impressions about using podcasts as a learning tool. The particular aim of this study was to help learners do research in English in their specific academic field. In their EAP course the learners are expected to study various types of English texts, listen to media and give lectures on their academic findings. The findings of this study revealed that males found podcasting significantly more relevant and attractive than females. Females, on the other hand, were significantly more satisfied with using podcasts in their EAP class. Further, results showed that learners who had no prior experience of podcasts for academic purposes outperformed the learners with medium experience. For further qualitative investigation, several sources were used for data collection including interviews with the learners, the course forums, emails, the class groupblog, podcasts and open-ended questions. Overall podcasting proved highly effective in motivating the students to learn in the online environment. 相似文献

With a focus on the Hindi language superhero comics produced by Raj Comics since the 1980s, this article investigates instances of “modernities in the backyard” and their implications for studying postcolonial popular culture. The graphic narratives in the comic books are neither simply Westernized or transgressive, nor necessarily framed by a mythicized or Orientalised discursive framework. Instead, they register a distinctive heritage combining vernacular and mythic prototypes with hypermodern visions with which to imagine new powers for Indian men and women, even though women may continue to be shaped by the masculinist, desirous gaze and modulated by patriarchal expectations to do with female docility and marriageability. The enquiry provides unique material to chart out the lineaments of postcolonial culture, gender, and power in order to provincialize the scope of cultural studies. 相似文献

This study illustrates design optimization for multiple wind towers located at different villages in Alaska. The towers are supported by two different types of foundations: large mat or deep piles foundations. Initially, a reinforced concrete (RC) mat foundation was proposed. Where soil conditions required it, a pile foundation solution was devised utilizing a 30 in thick RC mat containing an embedded steel grillage of W18 beams and supported by 20-24 in grouted or un-grouted piles. For faster installation and lower construction cost, all-steel foundations were proposed for these remote Alaska sites. The new all-steel design was found to reduce the natural frequencies of the structural system due to softening the foundation. Thus, the tower-foundation system could potentially become near-resonant with the operational frequencies of the wind turbine. Consequently, the likelihood of structural damage or even the collapse is increased.A detailed 3D finite-element model of the tower-foundation-pile system with RC foundation was created using SAP2000. Soil springs were included in the model based on soil properties obtained from the geotechnical investigation. The natural frequency from the model was verified against the tower manufacturer analytical and experimental values. When piles were used, numerous iterations were carried out to eliminate the need for the RC and optimize the design. An optimized design was achieved with enough separation between the natural and operational frequencies. The design successfully avoids damage to the structural system, while eliminating the need for any RC in most cases. 相似文献

This longitudinal study modeled children's complex executive function (EF) development using the Groton Maze Learning Task (GMLT). Using a cohort-sequential design, 147 children (61 males, 5.5–11 years) were recruited from six multicultural primary schools in Melbourne and Perth, Australia. Race/ethnicity data were not available. Children were assessed on the GMLT at 6-month intervals over 2-years between 2010 and 2012. Growth curve models describe age-related change from 5.5 to 12.5 years old. Results showed a quadratic growth trajectory on each measure of error—that is, those that reflect visuospatial memory, executive control (or the ability to apply rules for action), and complex EF. The ability to apply rules for action, while a rate-limiting factor in complex EF, develops rapidly over early-to-mid childhood. 相似文献

In this paper, we demonstrate biphasic microfluidic droplets with broadly tunable internal structures, from simple near-equilibrium drop-in-drop morphologies to complex yet uniform non-equilibrium steady-state structures. The droplets contain an aqueous mixture of poly(ethylene glycol) (PEG) and dextran and are dispensed into an immiscible oil in a microfluidic T-junction device. Above a certain well-defined threshold droplet speed, the inner dextran-rich phase is "stirred" within the outer PEG-rich phase. The stirred polymer mixture is observed to exhibit a near continuum of speed and composition-dependent phase morphologies. There is increasing interest in the use of such aqueous two-phase systems in microfluidic devices for biomolecular applications in a variety of contexts. Our work presents a method to go beyond equilibrium phase morphologies in generating microfluidic "multiple" emulsions and at the same time raises the possibility of biochemical experimentation in benign yet complex biomimetic milieus. 相似文献
