The 2003 Heat Wave in France: Dangerous Climate Change Here and Now

In an analysis of the French episode of heat wave in 2003, this article highlights how heat wave dangers result from the intricate association of natural and social factors. Unusually high temperatures, as well as socioeconomic vulnerability, along with social attenuation of hazards, in a general context where the anthropogenic contribution to climate change is becoming more plausible, led to an excess of 14,947 deaths in France, between August 4 and 18, 2003. The greatest increase in mortality was due to causes directly attributable to heat: dehydration, hyperthermia, heat stroke. In addition to age and gender, combinatorial factors included preexisting disease, medication, urban residence, isolation, poverty, and, probably, air pollution. Although diversely impacted or reported, many parts of Europe suffered human and other losses, such as farming and forestry through drought and fires. Summer 2003 was the hottest in Europe since 1500, very likely due in part to anthropogenic climate change. The French experience confirms research establishing that heat waves are a major mortal risk, number one among so-called natural hazards in postindustrial societies. Yet France had no policy in place, as if dangerous climate were restricted to a distant or uncertain future of climate change, or to preindustrial countries. We analyze the heat wave's profile as a strongly attenuated risk in the French context, as well as the causes and the effects of its sudden shift into amplification. Research and preparedness needs are highlighted.

An Exploration of “Superb Competences” in College Teachers in the Context of U-Learning

Ubiquitous learning (U-learning), a potential shortcut for China to modernize its education, is treated in this discussion as a mentality and means for citizens in high-tech society to seek a lifelong education. Thus situated, this article presents an exploration of “superb competences”—material intelligence, internet thinking, and brain-related neuro knowledge—in college teachers outside their trained professional areas. It is believed that once the teachers are equipped with the material intelligence, internet thinking, and brain-related neuro knowledge, real U-learning practice is ensured and its rationale will be developed. Material intelligence and internet thinking are evolved from and closely related to technological development, and therefore constitute the essential requirements of U-learning in terms of technical and educational cognitive framework. A good knowledge of brain related neuroscience, the third competence, guarantees the scientific rooting of every element in the designing of U-leaning tasks, whose success resides in a serious respect of cognitive nature and rules of the brain. The building of such superb competences, as is argued at the end of the paper, relies on various supports, like policies and technological aids, from all levels of educational administration in the country as well as each individual teacher’s personal understanding and efforts.     

Spatial Data Usage,Spatial Thinking and Spatial Knowledge Generation: The Case of Planning Practitioners in Arequipa,Peru

Spatial thinking and spatial knowledge generation in decision-making are still not mature fields of study in planning research, despite these being crucial elements in addressing the issues of the twenty-first-century city. This article contributes to their understanding by exploring their interrelationships with spatial data usage. Through storylines, it analyzes the arguments that planning practitioners offer in support of infrastructure-led decisions in Arequipa (Peru), before and after spatial data usage. The article concludes that spatial data usage improve spatial thinking to different extents, yet suggests aligning spatial data generation and the inclusion of GIS-based spatial analyses with the spatial knowledge needed by routine planning practice.     

试析“韩流”与韩国对华文化外交

文化外交是主权国家利用文化手段达到特定政治目的或对外战略意图的活动。韩国对华文化外交的实施对"韩流"在中国的兴起及风行创造了友好的政治氛围,奠定了广泛的受众基础,提供了坚实的保障。它的主要特色在于:以对外文化交流机构为依托,以韩国语为载体,以文化产业为主导。"韩流"不仅为韩国带来了为数可观的直接和间接经济效益,还提升了韩国的国家形象,改变了中国大众的对韩印象,对加强中韩民众的相互信任起到十分重要的作用。

Model-based clustering of multivariate skew data with circular components and missing values

Motivated by classification issues that arise in marine studies, we propose a latent-class mixture model for the unsupervised classification of incomplete quadrivariate data with two linear and two circular components. The model integrates bivariate circular densities and bivariate skew normal densities to capture the association between toroidal clusters of bivariate circular observations and planar clusters of bivariate linear observations. Maximum-likelihood estimation of the model is facilitated by an expectation maximization (EM) algorithm that treats unknown class membership and missing values as different sources of incomplete information. The model is exploited on hourly observations of wind speed and direction and wave height and direction to identify a number of sea regimes, which represent specific distributional shapes that the data take under environmental latent conditions.     

形象与抽象思维论

形象思维和抽象思维始终共处于人类思维之中,思维成为主要方面时,就由一种形态转化为另一种形态,不停地从形象到概念,又从概念回到形象。每一次循环,都促进思维的进一步深化;多次的深化,便引起飞跃。这就是我们所理解的形象思维和抽象思维对立统一关系的基本内容。
