Food preparation skills among young adults are associated with healthy food choices, better diets and a greater likelihood of an independent, healthy adult life. This study conducted in Hong Kong aimed to investigate parents' perceptions of cooking skills; to explore the transference of cooking skills in the home setting; to identify parents' expectations regarding the transference of cooking skills; and to inform the development of educational initiatives for developing healthy eating habits. A questionnaire survey was conducted to collect information of the subjects' cooking experience, attitudes about cooking skills, cooking habits at home, family meal habits, transference of cooking culture in the family and the factors influencing the choice of ingredients and cooking. It was administered to 1009 Hong Kong parents (of students aged between 11 and 18, studying in 15 secondary schools). The collected data were analysed using the Statistical Package for the Social Sciences (version 12.0, SPSS, Inc., Chicago, IL, USA) and cross‐tabulation analyses were used to compare the responses of the parents by gender, employment status and income. The results show that parents valued cooking as important life skills for both boys and girls. Parents generally perceived their cooking skills either good (41.9%) or mediocre (54.5%), yet children are rarely taught these skills in the home. Family meals prepared primarily with fresh ingredients are still an important part of the daily routine, and mothers are dominating the roles in food choice decision, cooking and buying the ingredients for family meals. Mothers and schools are expected to be the major channel to teach children cooking skills. Findings suggest that parents are well‐disposed towards providing food and nutrition education at home, but need more support (50% reported that home should be a primary support for learning cooking skills; 36% indicated that the school should have a responsibility to teach children to cook starting in elementary school). Schools may do well to collaborate with families in food literacy education initiatives. Developing individuals' cooking skills paves the way for long‐term health benefits and the well‐being of the local population. 相似文献

谨慎性原则是基本的会计准则之一,《企业会计准则》规定企业应合理地计提资产减值准备,这项政策既使企业可以正确、公允地报出自己拥有资产的价值,也使信息使用者能得到对决策相关有用的信息,同时又利于税务机关对税收的控制。尽管对政策的不合理利用仍然存在,但随着制度的健全,会计人员素质的提高,政策实用性的前景很被看好。 相似文献

Correctness of an emergency response process specification is critical to emergency mission success. Therefore, errors in the specification should be detected and corrected at build-time. In this paper, we propose a resource conflict detection approach and removal strategy for emergency response processes constrained by resources and time. In this kind of emergency response process, there are two timing functions representing the minimum and maximum execution time for each activity, respectively, and many activities require resources to be executed. Based on the RT_ERP_Net, the earliest time to start each activity and the ideal execution time of the process can be obtained. To detect and remove the resource conflicts in the process, the conflict detection algorithms and a priority-activity-first resolution strategy are given. In this way, real execution time for each activity is obtained and a conflict-free RT_ERP_Net is constructed by adding virtual activities. By experiments, it is proved that the resolution strategy proposed can shorten the execution time of the whole process to a great degree. 相似文献

This project requires you to create financial statements using FRx within Microsoft Dynamics GP, an enterprise system. The project emphasizes the learner-centered paradigm rather than a teacher-centered educational paradigm. Researchers have found great importance in the learner-centered approach in educating students, especially in information systems (Landry, Saulnier, Wagner, & Longenecker, 2008; Saulnier, Landry, & Wagner, 2008). Major differences exist between the two approaches; for example, the professor gives information and evaluates, and emphasizes the right answer in a teacher-centered approach. The professor coaches and facilitates, and emphasizes that students generate good questions and learn from mistakes in a learner-centered approach. This project utilizes the learner-centered approach, an effective approach for you to use in today’s environment. 相似文献

Intention, as the starting point of pursuing self-employment and creating new ventures, is crucial before actually establishing a business enterprise. Entrepreneurship is understood to be an essential ingredient for enhancing a country's economic competitiveness, growth, and sustainability while confronting the escalating challenges of globalization, such as increasing unemployment. This study provides empirical evidence on the factors influencing entrepreneurial intention and startup preparations among university students in Malaysia. The findings provide scholars and academic policymakers with insights into the effectiveness of Malaysia's entrepreneurial education as designed and practiced by public universities. The Malaysian government should apply these findings to fortify existing policies and programs and formulate new ones to support graduate entrepreneurs, while universities and other higher education institutions should provide high-quality entrepreneurial courses and programs to young Malaysians to foster an inclination toward entrepreneurship. 相似文献
