Hollywood at that time, because of the monopolization of the so-called "eight movie companies", the shooting and operation of a film followed rigorous steps of "producer system." The target of the "producer system" entirely aimed at the market in order to get the maximum profits; therefore, although this system brought a lot of money to the film industry, it also limited the filmmakers' play space. Thus, a group of filmmakers got rid of the eight movie companies' control and made self-financing, or even wrote and direct red by themselves, they shot a lot of strong ideological films which were different with commercial films, known as the" Independent Film ".展开更多

Under this influence, primary school students’ independent reading has also been changed. However, due to limited self-control and understanding, primary school students face certain difficulties when using online teaching platforms for independent reading. Advantages and disadvantages of distance learning based on the network teaching platform were summarized in this paper. A one-year experiment study was carried out on our school fifth-grade students in independent reading using WeChat campus platform considering their current situation and existing problems of independent reading. In experiment study an independent reading mode was introduced. The results show that this reading mode can significantly improve students’ independent reading ability.展开更多

This study provides background information on India's Western Himalayas and reviews evidence of warming as well as variability in precipitation and extreme events.Methods: Understanding and anticipating the impacts of climate change on Himalayan forest ecosystems and the services they provide to people are critical. Efforts to develop and implement effective policies and management strategies for climate change mitigation and adaptation requires particular new research initiatives. The various studies initiated and conducted in the region are compiled here.Results: Several new initiatives taken by the Himalayan Forest Research Institute in Shimla are described. This includes new permanent observational field studies, some with mapped trees, in high altitude transitional zones for continuous monitoring of vegetation response. We have also presented new strategies for mitigating potential climate change effects in Himalayan forest ecosystems.Conclusions: Assessment of the ecological and genetic diversity of the Himalayan conifers is required to evaluate potential responses to changing climatic conditions. Conservation strategies for the important temperate medicinal plants need to be developed. The impact of climate change on insects and pathogens in the Himalayas also need to be assessed. Coordinated efforts are necessary to develop effective strategies for adaptation and mitigation.展开更多

However, little is known about the mechanisms controlling caste determination in eusocial wasps. Evidence suggests that the phenotype of queens in independent-founding (IF) eusocial wasps of the subfamily Polistinae can be partly fixed in the larval stage;however, this hypothesis has not yet been investigated. In this study we evaluate whether juvenile hormone (JH) affects pre-imaginal caste determination in the IF eusocial wasp Mischocyttarus consimilis (Hymenoptera: Vespidae). Analyzing morphometric and behavioral data, we demonstrated experimentally that females emerging from larvae that were treated with JH in the third instar had a significantly larger body size, spent more time in the nest, and were subject to less physical aggression from nestmates compared with females emerging from untreated control larvae. These results indicate that phenotype differences among castes in IF eusocial wasps can be partly fixed in the pre-adult stage and influenced by variations in the JH titer.展开更多

Therefore, ...Background: There are numerous teaching strategies that suit the pedagogical learning, but not all can yield the desired outcome and be properly applied by nurse tutors in both classroom and clinical area. Therefore, identifying the utilization of the teaching strategy for nurse tutors is very detrimental in nursing education. Methods: Descriptive exploratory design which utilized both qualitative and sequential quantitative methods was applied to Iterated Purposive Probability Sampling (IPPS) of 10 nursing colleges in Malawi. This was done to 129 student and 82 nurse tutors in two structured questionnaires, 40 in-depth interviews and 10 focus groups. There were 56 variables for the teaching strategy under five ranked Likert scale and the Cronbach’s Alpha was found to be 0.964 without standardisation and it was 0.963 after standardisation. Results: Direct teaching strategies like the lecture method are very common although nurse tutors prefer to combine with other interactive instructions. There is statistical association of use of role play and group discussion methods and nurse tutor work experience with odds ratios of OR ≤ 1.624;CI(0.576 ± 4.579);p ≥ 0.359 and OR ≤ 1.397;CI(0.882 ± 2.306);p ≥ 0.147 respectively. The ability to use different teaching strategies competently is still very limited among nurse tutors in Malawi nursing colleges. This compromises quality of learning among nursing students in the colleges. Conclusion: Developing a new teaching strategy that could combine the different attributes in the variety of the teaching instructions can promote the quality of nursing education in Malawi.展开更多
