北京城市老年人购物决策过程中的评价性认知特征   总被引:6,自引:1,他引:5  
本文以北京城市老年人购物行为问卷调查数据和访谈资料为基础,揭示北京城市老年人购物决策过程中的评价性认知特征。影响北京城市老年人食品类购物决策最主要的三个因素依次为购物地离家距离、食品价格因素和购物地所提供食品种类丰富程度,有低成本主导型的倾向;日用品类购物决策时考虑的最主要的三个因素依次为购物地离家距离及购物地所提供地商品种类丰富程度和商品的价格和质量,有低成本和高收益并重的特点。同时,随着购物地离家距离的增加,距离因素的重要程度有下降的趋势,而商品特性的评价认知重要程度则不断上升。  相似文献

清华国学研究院(1925-1929),是在"整理国故"运动中涌现的一个著名学术机构。与同时期其他国学机构相比,清华国学研究院既有援引西学,重建现代学术体系的一面;又有继承儒家教育理想与治学路径,结合西方知识工具,致力于阐发传统学术之特质的一面。因此,清华国学研究院的学术建制,学术社群的治学精神,皆有其鲜明的特性。  相似文献

Using results from a survey and focus groups with staff and students, I evaluate best practice for student-focused assessment criteria, including the value of specific assessment criteria, where and when students engage with criteria, the use of exemplars, how assessment criteria connect to feedback and the importance of bringing students more actively into the assessment process. I argue that we need to accept that many students are assessment motivated, and rather than work against this reality (which is rarely successful), we should instead consider how assessment can address student concerns of clarity and fairness while being more tied into learning.  相似文献

Abstract: This article draws on the strategic‐relational approach in state theory and examines the transformation of the Mexican state into internationalized competition state. It does so by analyzing the rise of the neoliberal forces and the neoliberal state project inside Mexico during the 1970s while taking into account the important modifications in the international division of labor and the evolving international regulation. These developments resulted in the transformation of the Mexican state into an internationalized competition state which adopts a Ricardian strategy of competition and is characterized by the tendencies towards the denationalization of statehood and the internationalization of policy regimes.  相似文献

In this paper I explore how post-depositional contaminants and non-use related ancient residues may be distinguished from use-related residues directly associated with the application of ancient artefacts. It is assumed that contaminant and unintentional remains have a random distribution over a tool’s surface. Preserved use-related residues, however, are expected to have a consistent spatial distribution around a working edge. To test this, residues on used and unused experimental flakes were recorded after they underwent weathering. The surfaces of the experimental flakes were divided in four quadrants, of roughly equal size. The surface coverage of the residue types per quadrant was then recorded. On used flakes with well preserved residues, the use-related residues are more abundant on portions associated with the sharp edge than on portions associated with blunt sides. On the samples without identified use-related remains and on the unused sample, the distribution of micro-remains is more uniform. This study confirms that by using a contextual approach it is possible to distinguish use-related remains from non-use-related and co-incidental remains.  相似文献

This paper presents a case study aimed at correlating archaeological ‘events’ (obtained from radiocarbon measurements and dendrochronology) from the site of Sutton Common with a radiocarbon-dated pollen sequence obtained from a palaeochannel deposit adjacent to the area of the main archaeological activity. It demonstrates the use of a Bayesian approach to quantifying whether the timing of palynological ‘events’ interpreted as reflecting anthropogenic impacts are likely to be associated with archaeological ‘events’. The results suggest that Bronze Age activity in the form of a mortuary enclosure and associated cremation burials are probably not contemporary with the palynological evidence for disturbance to the oak–hazel woodland in this period. Subsequent evidence for local woodland clearance and agriculture is estimated to precede the construction of the large Iron Age enclosure in 372 BC, with increases in ‘anthropogenic indicators’ following this ‘event’. The construction of the site does not appear to have had a pronounced impact on the local vegetation, with hazel the only woody taxon to show clear reductions. Despite the use of a substantial number of oak timbers in the enclosure palisade, percentages of oak remain remarkably stable. Later farming activity on the site probably post-dates the end of activity in the enclosures. The value of the methodology is discussed in relation to quantifiable and robust correlations of archaeological and palaeoenvironmental narratives of landscape and human activity.  相似文献

Academic and popular accounts of the Opium War have gone through nearly two centuries of change in focus, view, and scope. My study probes this extensive historiography by tracing the evolvement of our understanding of the war through various phases among which we saw the rise of the “China-centered approach” and the beginning of a new trend towards combining government archives with personal records such as memoirs, personal correspondence, and private journals in research. Based on the observation, I will indicate, despite their undeniable achievements, most of the existing scholarships have paid little attention to the ordinary people in China whose lives were deeply affected by the war. It is high time that we pay more attention to human experience of the Chinese people in order to understand not only the war itself but also the history it helped shape.  相似文献

汪家嘴遗址是江汉平原与澧水流域过渡地带的一处重要的商代遗址,时代从二里岗上层偏早延续到殷墟二、三期。其文化特征与湖南澧水流域青铜文化皂市类型之土著因素保持强烈的一致性,中原商文化的因素极少或不见,是一个典型的地域类型。本报告运用了考古界面理论和存在背景关系理论,不仅为该遗址的研究提供了更多有价值的信息,而且为今后考古报告的科学编写提供了借鉴。  相似文献

Several cities in Sweden have been providing book-printing facilities since the 1640s. In our quantitative and explorative analysis of library catalogs from the National Library of Sweden and the National Library of Finland we identify the general trends in publishing, how book-printing has been affected by political events, and how printing developed at different paces in different parts of the realm. We have developed a new method for analyzing the totality of publishing through extensive data harmonization and comprehensive statistical analysis, and by treating library catalogs not as an endpoint of bibliographic research but as an inherently rich source of information. This facilitated the quantitative assessment of printing in the Swedish realm based on the metadata contained in library catalogs. Our data-driven approach to the transformation of public discourse demonstrates that whereas the amount of printed material grew steadily, political ruptures affected the development of printing. We also suggest that the culture of books and printing is best understood through the dynamics of competing intellectual hubs consisting of the university cities and the political center in Stockholm. This perspective further challenges the dominant, nationally delineated approach in book history.  相似文献

Different models of emotional lateralization, advanced since the first clinical observations raised this issue, will be reviewed following their historical progression. The clinical investigations that have suggested a general dominance of the right hemisphere for all kinds of emotions and the experimental studies that have proposed a different hemispheric specialization for positive vs. negative emotions (valence hypothesis) or for approach vs. withdrawal tendencies (motivational hypothesis) will be reviewed first and extensively. This historical review will be followed by a short discussion of recent anatomo-clinical and activation studies that have investigated (a) emotional and behavioral disorders of patients with asymmetrical forms of fronto-temporal degeneration and (b) laterality effects in specific brain structures (amygdala, ventro-medial prefrontal cortex, and anterior insula) playing a critical role in different components of emotions. Overall, these studies support the hypothesis of a right hemisphere dominance for all components of the emotional system.  相似文献
