《食品营养与卫生学》是食品科学与工程专业的必修课之一。为适应应用型本科院校教学的发展需要,提高教学质量,激发学生的学习兴趣,近年来,我们在《食品营养与卫生》课程教学中探索了讲授式教学法(LBL)—问题教学法(PBL)—案例教学法(CBL)—小组教学法(TBL)等多种教学方法有机结合的"联合教学法"。本文比较了几种教学方法的适用条件、操作要点和各自的优缺点,并选择教材中一章的内容为例,在教学实践中将多种教学方法联合使用,做了简要分析与探讨,以期为更好地培养以能力为导向的应用型人才的教学方法提供参考依据。 相似文献

Predicting food preferences is challenging due to the numerous factors that can influence individual taste. Cultural influences are one such factor that can significantly impact food preferences. Irrespective of culture, however, food visual aesthetics drive food choice. With this in mind, we study 15,000 images of food from prominent recipe portals in China, the US and Germany with the aim of identifying common visual trends related to food choice. We report that distinguishing between appreciated and less appreciated recipes based on visual features through multiple machine learning experiments is possible, with a maximum accuracy of 67%. The classifiers trained on one culture, when applied to other cultures, reveal that appreciated recipes from US and German portals share visual similarities, while the visual aspects making recipes attractive for Chinese users differ. Complementing our machine learning experiments, we conducted a user study with 450 participants from the three cultures. Participants are asked to rank recipes based on their appeal and provide justification through answering 19 questions. The results reveal significant predictors of preference, including perceived appearance and taste across all countries, and negative perception of perceived healthiness for US and German participants. Analysis of 77 consistently labelled appealing/non-appealing images reveal significant variations in low-level visual features such as colourfulness, sharpness, and contrast. These findings suggest that these low-level visual features may play a critical role in determining whether an image is perceived as appealing or not across different cultures. Our results offer promising insights into the development of cross-culture food recommender systems. By demonstrating common ground across food cultures, we believe that these systems can provide personalised meal suggestions that reflect user’s preferences while incorporating ideals such as healthfulness and sustainability. 相似文献

Abstract Self-help groups (SHGs) have emerged as an effective mechanism of empowerment and development of women as well as being on efficient mode of promoting group action and technology dissemination. Initiatives were undertaken at the Central Institute of Post-Harvest Engineering and Technology (CIPHET), Ludhiana to facilitate the formation of women's SHGs and to develop their capabilities through training programmes for harnessing the benefits of value addition and processing technologies for employment and income generation. The study attempts to assess the attitude changes in women about SHGs as a result of training. The evaluation of SHGs was conducted at attitude construct. A Likert-type scale consisting of 26 items was developed, for which Cronbach's alpha coefficient of reliability was observed as 0.85. The survey instrument contained five sections; namely, socio-economic upliftment; education and training; marketing and entrepreneurship qualities; technology adoption and participatory research; and banking/credit aspects. The training group consisting of 30 participants of SHGs responded to five-section survey instrument. Significant t-test results for mean values of attitude of women before and after the training showed a significant change in attitude of women in all the five areas as a result of training. Positive orientation towards a task paves the way for success. The study exemplifies the impact of training in instilling positive orientation. For addressing the issues of rural poverty, enrichment of the system with social capital through empowerment and formation of women SHGs; provision of financial and credit support; creation of market-driven and decentralized extension system; use of media-mix for technology transfer and informal education at rural level; conduction of need-based training and strong political will need to be emphasized. 相似文献

Abstract One of the main problems in Southern Africa in relation to HIV/AIDS is food insecurity. The vicious relation between malnutrition, HIV infection and AIDS impact drives individuals, households and communities in a downwards spiral of impoverishment. Although scientists and development practitioners have stressed the importance of interactive approaches to mitigate the impact of AIDS on agriculture and rural development, sustainable implementation is far from easy and straightforward. This study aims to gain insight into the main lessons and challenges with respect to their design and implementation. Literature review of interactive approaches in agriculture and natural resource management shows that several principles and process guidelines are considered key factors to successful implementation. Although HIV/AIDS does not seem to change these conditions, personal experiences from researchers, development practitioners and extension workers do reveal new and unforeseen challenges. 相似文献

梁实秋的《雅舍谈吃》和周作人的《知堂谈吃》早就被人视为饮食散文的精品,读之深沉隽永,耐人寻味.它们同是谈吃,作品中常常有共通之处,都有故乡情怀、平民情怀、生活情怀蕴于其中,这与两们作家的士大夫情怀和自由主义思想有着密不可分的关系;但是周作人的饮食散文,可以从淡淡的闲适中品味到苦味、涩味,而梁实秋却以乐生的态度去感悟人生三味. 相似文献

人的饮食就不单纯是生理意义上的活动,而是有了深刻的社会意义和人格内涵。《儒林外史》中的饮食有很高的讽刺意味。它从刻画人物的性格入手而非一般意义上的文化分析,使得《儒林外史》中的饮食讽刺更鲜明和更突出。 相似文献
