高职毕业生就业率缺口探析

高等职业教育是我国高等教育体系的重要组成部分.以就业为导向是高职院校办人民满意教育的关键环节.就业率的统计依然是各省、各高职院校完成就业指标,体现教育成果,构筑和谐社会的有效体现.但对就业率缺口的关注还存在一定的误区和盲区,本文试图通过就业率缺口的探析,找出有效解决未就业毕业生的就业途径,提高就业工作的实效性和针对性,切实提高就业率.     

《已故上校的女儿们》中的象征意象分析

《已故上校的女儿们》是著名短篇小说家凯瑟琳·曼斯菲尔德的经典之作。这篇小说独特的叙事结构、淡化的故事情节和巧妙转换的叙述角度为人们所津津乐道,与此同时,曼斯菲尔德对象征意象的娴熟运用也让这篇小说意味深长、回味无穷。作品中象征性意象分为三类,分别象征着父权主义、维多利亚时代妇女的希望和她们的实际地位。通过对这些意象的分析,读者可以更深刻地理解该小说及曼斯菲尔德的写作风格。

Application of network meta-analysis in the field of physical activity and health promotion

Continued advancement in the field of physical activity and health promotion relies heavily on the synthesis of rigorous scientific evidence. As such, systematic reviews and meta-analyses of randomized controlled trials have led to a better understanding of which intervention strategies are superior (i.e., produce the greatest effects) in physical activity-based health behavior change interventions. Indeed, standard meta-analytic approaches have allowed researchers in the field to synthesize relevant experimental evidence using pairwise procedures that produce reliable estimates of the homogeneity, magnitude, and potential biases in the observed effects. However, pairwise meta-analytic procedures are only capable to discerning differences in effects between a select intervention strategy and a select comparison or control condition. In order to maximize the impact of physical activity interventions on health-related outcomes, it is necessary to establish evidence concerning the comparative efficacy of all relevant physical activity intervention strategies. The development of network meta-analysis (NMA)—most commonly used in medical-based clinical trials—has allowed for the quantification of indirect comparisons, even in the absence of direct, head-to-head trials. Thus, it stands to reason that NMA can be applied in physical activity and health promotion research to identify the best intervention strategies. Given that this analysis technique is novel and largely unexplored in the field of physical activity and health promotion, care must be taken in its application to ensure reliable estimates and discernment of the effect sizes among interventions. Therefore, the purpose of this review is to comment on the potential application and importance of NMA in the field of physical activity and health promotion, describe how to properly and effectively apply this technique, and suggest important considerations for its appropriate application in this field. In this paper, overviews of the foundations of NMA and commonly used approaches for conducting NMA are provided, followed by assumptions related to NMA, opportunities and challenges in NMA, and a step-by-step example of developing and conducting an NMA.     

Replication,pathogenicity, and transmission of SARS-CoV-2 in minks

Minks are raised in many countries and have transmitted severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to humans. However, the biologic properties of SARS-CoV-2 in minks are largely unknown. Here, we investigated and found that SARS-CoV-2 replicates efficiently in both the upper and lower respiratory tracts, and transmits efficiently in minks via respiratory droplets; pulmonary lesions caused by SARS-CoV-2 in minks are similar to those seen in humans with COVID-19. We further found that a spike protein-based subunit vaccine largely prevented SARS-CoV-2 replication and lung damage caused by SARS-CoV-2 infection in minks. Our study indicates that minks are a useful animal model for evaluating the efficacy of drugs or vaccines against COVID-19 and that vaccination is a potential strategy to prevent minks from transmitting SARS-CoV-2.

广告信息传播研究

广告是人类社会发展到一定阶段的产物,是由广告主通过付费所获得的一种自我宣传手段,它借助一定的媒体,向目标公众或目标市场传播信息、思想、观念和自我形象等[1].根据广告的最终目的,广告可分为商业广告和公共服务性广告.广告信息传播主要由广告主、广告信息、广告媒介、广告受众等要素组成,在现代社会中,广告已突破经济的界限,渗透到社会的方方面面,广告与社会、与人类的关系日益密切.然而广告作为信息传播的一种特殊方式,具有特殊的目的和意义,广告本身也存在着特殊性.本文就广告信息传播的特殊性、广告信息传播中的信息污染及管理问题进行探讨.

收藏新粉彩文人瓷画的一点体会

民国瓷器是我国陶瓷发展史上一个重要的转型时期。随着满清王朝在内外交困中轰然倒塌,瓷部景德镇延续了几百年的御窑厂也成为了历史的陈迹。但传承千年的制瓷技艺、身怀绝技的能工巧匠和颇富造诣的艺术人才并未烟消云散,依然聚集在此。在列强入侵和洋货冲击下,他们奋发图强,创造出许多无愧于时代的新技术、新产品,为瓷都再次谱写了绚丽的篇章。同时,流落民间的一些艺术家,也为景德镇的制瓷业注入了新鲜的血液,使宫廷艺术、民间艺术和文人艺术融合在一起。而彩绘业更是得到了长足发展,并涌现出一批出类拔萃的技术人才。由于原来朝廷的俸禄已不复存在,使得这些艺人们不得不直接面向市场,迫使他们潜心研究。不断创新。在这种情况下,具有竞争力的浅绛瓷画和稍后的新粉彩瓷画应运而生。
