Syzygium campanulatum Korth is a plant, which is a rich source of secondary metabolites (especially flavanones, chalcone, and triterpenoids). In our present study, three conventional solvent extraction (CSE) techniques and supercritical fluid extraction (SFE) techniques were performed to achieve a maximum recovery of two flavanones, chalcone, and two triterpenoids from S. campanulatum leaves. Furthermore, a Box-Behnken design was constructed for the SFE technique using pressure, temperature, and particle size as independent variables, and yields of crude extract, individual and total secondary metabolites as the dependent variables. In the CSE procedure, twenty extracts were produced using ten different solvents and three techniques (maceration, soxhletion, and reflux). An enriched extract of five secondary metabolites was collected using n-hexane:methanol (1:1) soxhletion. Using food-grade ethanol as a modifier, the SFE methods produced a higher recovery (25.5%?84.9%) of selected secondary metabolites as compared to the CSE techniques (0.92%?66.00%). 相似文献

As part of a comparative study of attitudes toward freedom ofexpression, Americans, Israeli Jews, and Israeli Arabs wereasked about the social contexts in which they feel unfree tospeak and about the reasons that inhibit them. Home was theleast inhibiting locus in all three cultures and, for the U.S.respondents, the workplace was most inhibiting. Responding toa battery of 33 reasons for not speaking out, all three culturesgave highest ratings to items related to the fear of hurtingothers. Questions measuring fear of being disapproved or hurtby others—including fear of isolation from the majorityand fear of legal restraint—were ranked lower. An overallindex of inhibition items proved highly reliable cross-culturally.Americans claimed least inhibition and Israeli Arabs most. Malesand those with higher education levels and incomes were alsoless inhibited across the three cultures. Expression inhibitionwas negatively, through weakly, related to support for expressiverights among both Israeli groups and American whites but notAmerican blacks, where the relation was positive. Expressioninhibition was negatively related to political activity amongAmericans and Israeli Jews but not among Arabs. 相似文献

Objectives
The Convention on the Rights of the Child (CRC) was ratified by Saudi Arabia 15 years ago; yet addressing the issue of child maltreatment only began in more recent years. School professionals play a significant role in children's lives, as they spend a great deal of time with them and are hence essential to protecting and identifying those in danger or at risk. The objective of this study is to identify school professional's awareness of child maltreatment and the existing national policies and procedures to examine the extent of efforts made in Saudi Arabia and to activate the roles of schools and school professionals in protecting children from violence and implementation of Article 19 of the CRC.Methods
This was a cross-sectional study, where school professionals from randomly selected schools throughout the country were invited to participate in a self-administered questionnaire.Results
A total of 3,777 school professionals participated in the study. Fifty-five percent of professionals had at least 10 years of work experience. A low-level of awareness of child maltreatment was found in about 1/3 of school professionals. Only 1.9% of school professionals had ever attended any sort of specific training on child maltreatment, though 69.3% of those who had not, were willing to attend future training. With regards to awareness of CRC Article 19 or policies and procedures addressing child maltreatment, only 22% reported being aware of it.Conclusion
The majority of school professionals in Saudi Arabia have a low-intermediate level of awareness of child maltreatment, ratification of CRC, and related national policies and procedures, yet most are willing to attend training programs on this subject matter. Efforts need to be made in the country to fill this gap. 相似文献19.

Recommender systems have dramatically changed the way we consume content. Internet applications rely on these systems to help users navigate among the ever-increasing number of choices available. However, most current systems ignore the fact that user preferences can change according to context, resulting in recommendations that do not fit user interests. This research addresses these issues by proposing the \(({ CF})^2\) architecture, which uses local learning techniques to embed contextual awareness into collaborative filtering models. The proposed architecture is demonstrated on two large-scale case studies involving over 130 million and over 7 million unique samples, respectively. Results show that contextual models trained with a small fraction of the data provided similar accuracy to collaborative filtering models trained with the complete dataset. Moreover, the impact of taking into account context in real-world datasets has been demonstrated by higher accuracy of context-based models in comparison to random selection models. 相似文献

The purpose of the present study was to assess to what extent moments of experiencing enjoyment in communicating in English as a foreign language is transparent to the teacher and the peers within the ecology of the classroom using an idiodynamic approach. To do this, we explored four university students’ self, teacher and peers reading of nonverbal language enjoyment cues in terms of their face, gesture, gaze, vocalics and posture in a course of general English. The participants prepared for a short presentation on a favourable subject and were video recorded to self-rate themselves immediately after the presentation using Anion Variable Tester V2 software. Two peers, one among the participants’ inner circle friends and the other an outer-circle classmate, and the teacher rated the videos of the presentations. The ratings were compared to find points of convergence indicating the extent of transparency of enjoyment in communication. The findings of the study indicate mixed and dynamic outcomes which, confirming the unstable and complex nature of enjoyment, show that transparency of enjoyment in foreign language communication seems to be an illusion. 相似文献
