技术世中教育的加速隐忧及其超越

人类世描绘着人与自然的“脱嵌”,其典型特征是人类以技术手段过度征用自然,造成自然的不断熵增。同时,人类世还表征着以人工智能为核心的现代技术对“自然人”的技术改造,构成现代性加速危机。人类世是技术世,亦是教育世。当前,教育被裹挟进技术世的“加速逻辑”中,教育时空在加速博弈中走向结构异化;在对技术加速的迷恋之中,学生的自由发展与精神世界被辖制,师生整体性地陷入了行动“倦怠综合征”,教育的本真意义在加速中迷失了方向。为超越技术世给教育带来的加速困境,教育仍需基于生命本真重塑教育的时空结构;在寻求凝思、敞开自我、回归现实的过程中寻求教育的积极行动;最终在人机共鸣之中重塑教育的意义,实现“技术—人—自然—社会—世界”的融合构筑。

人类世、资本世与技术世——一个政治经济学—政治生态学的考察

包括诺贝尔化学奖得主克鲁岑在内的跨学科学者认为,工业革命以降的地球进入了新的地质学纪元,这个纪元被命名为“人类世”。“人类世”并不是对“人类”进行人类主义式的肯认,而是对“人类”作出去中心化与去特权化的后人类主义反思,并开启对“后人类世”的思想探索。“资本世”与“技术世”两个概念也从不同角度揭示出人类主义—资本主义这个现代性的双身结构在地球层面产生的诸种灭绝性效应。二十一世纪的当下时刻,“人类世文明”正走向深渊性的“奇点”,作为地球上的物种之一的人类已经生活在剩余时间中。能否跨越“人类世”,取决于当下人类是否能作为同一个文明(人类世文明)及其代价的承载者展开全球意义和尺度上的合作,乃至和地球上所有非人类的能动者展开合作。

技术乐观主义探析

技术乐观主义是人类最古老的技术观之一,它以技术决定论作为其理论前提,以技术的正面效应作为其研究的主要对象,以"技术救世"、"科技是生产力"、"技术创造文化"等思想作为其理论内核,在激励人们发明技术、运用技术、创造生活、改变世界的过程中发挥了极其重要的作用。虽然技术乐观主义存在着技术决定论的单向线性思维的片面性,但它对技术及其功能的认识仍不乏真知灼见的理性之光,依然是我们当今时代"科技立国"战略的思想源泉和新型"和谐技术观"构建的重要理论基础!

The Technological Gap between China and World Frontiers at the Industrial Level:1985-2009

Using sequential DEA methodology, this paper has measured the variations in the technological gaps of China＇s industrial sectors compared with the world frontiers of technology. From a temporal dimension, variations in the technological gaps of China＇s industrial sectors can be divided into the following four stages： slight abatement of technological gaps between 1985 and 1992, and between 1999 and 2007; stagnation in the variation of technological gaps between 1994 and 1999; and continuous abatement of technological gaps between 2008 and 2009. From the industry dimension, by 2009, 58.8% of China＇s industrial sectors had gradually reached or approached the world frontiers of technology; 29.4% of industrial sectors had experienced technological improvements but still lagged far behind the world frontiers of technology; 11.8% of industrial sectors significantly lagged behind the world frontiers of technology.

Techno-psychological Aspects of Social Media Behaviors

Social media has become an inevitable part of our lives in the age of network society. People establish multiple identities for themselves, with or without references to the real world, and behave according to those identities. Self-made components of virtual presence are not limited to identities only; many users also create hyper-personalities for themselves with the help of new technologies. Then, the fundamental question becomes： Why do people create self-made identities and hyper-personalities to portray or hide themselves in social media environments？ The answer to this question has certain connections and implications for behaviors of social media users. Therefore, researchers have investigated why some people find social media attractive and attend whenever possible, while others are afraid of social media and hesitate to attend. Positive and negative behaviors of social media users can be classified as braggadocian and preventative. Braggadocian behaviors are related to courageously taking advantage of social media, whereas preventative behaviors are concerned with avoidance of social media. The dominant behavioral pattern of a user depends on what one can achieve through attending or preventing social media. This paper first discusses basic elements of human behavior that drive social media such as altruism, hedonism, connectionism, homophily, multiple identities, memetics, narcissism, and tribalism. Then, it focuses on precautionary elements of human behavior such as avoidance, escape, blocking, fear, hiding, removal, and protectionism. Whether they are attentive or not, one thing is clear： People refrain or enrich their own lives in social media rather than being abused or watching others in industrial media.

Past, Present and Future of Military Food Technology

Food technology has been instrumental in ensuring that troops remain ＂fit to fight＂. Early food technologies produced flat bread, hard biscuits, cheese and salted meat, allowing Roman legionaries to carry rations for several days. Canning was invented in the late 18th century in response to the French Government＇s offer of a substantial reward to the person whose invention would allow troops to carry their food when marching long distances. World War II saw further advances in the form of stable and palatable canned meals, compressed cereal bars, candy-coated peanuts and other innovative foods in US combat rations. Two significant technology breakthroughs in the second half of the 20th century have altered the form of military rations. Freeze drying matured as an industrial technology, allowing the production of long-life, light-weight rations. Flexible packaging, based on plastic laminates, led to reduced weight and less waste disposal through the development of retort pouched meals （meals in flexible packaging that have undergone heat sterilization）, which have largely replaced metal cans in combat rations. Improvements in quality of military rations, particularly their organoleptic properties, are emerging through application of innovative technologies such as high-pressure thermal processing, pulsed electric field, and microwave assisted thermal sterilization. Research and development of ＂functional foods＂, such as those containing added essential fatty acids or probiotics offers the potential to provide combat rations that can further improve soldier health and performance.

Permanence of Economic Potential of Cities Based on Sector Development

The paper attempts to answer the following key question: how will a city′s world rank change in the face of crisis in its main economic sector? Crisis is defined here as a decline in financial performance in the given sector, which leads to the decline of its constituent firms and corporations on the world economic scene. The World Economic Center Index(WECI) has been created in order to rank cities based on the value of their resident corporations by sector and show their level of stability upon the removal of the most important sector. This provides information on the potential of each analyzed city as well as on its advanced features or area of specialization. Research has shown that nearly half the World Economic Centers are dominated by the financial and materials sectors of the economy. Different sectors dominate different regions of the world. For example, consumer staples and materials were dominant in North America, while information technology and financials were dominant in Europe. In Asia, several sectors tend to dominate the economy. Research has shown that the ability of a principal economic sector to resist economic crisis largely depends on the strength of the command and control function of a city. Finally, a high globalization level of a city is a key determinant of its susceptibility to economic crisis.

Geographical Patterns of Cultural Values, Entrepreneurship and Economic Development

Globalization and information technologies are new realities that have brought profound changes in lifestyles worldwide. This is reshaping the overall pattern of life custom, cultural production, consumption and trade in a world increasingly filled with changes and economic diversity. In an age of globalization, often ask questions and discussions concerning about successes and vitalities of nations. Globalization and technological revolutions race ahead and transform the world, and how to traces the real business to success. There are thousands of good examples where any nations have shown entrepreneurial talents and have succeeded. It is culture that principally explains, in many cases, or geographical pattern where some countries are developing more rapidly and more successfully than others. How to explain economic success of this nation＇s miracles or simple the secret is creative entrepreneurships？ This paper explores the complex interactions between the geographic pattern from one side and cultural, technological and social aspects of entrepreneurship from other side which generates the dynamic processes of the world economy. In this era of transformation, creativity and knowledge entrepreneurship are powerful tools of fostering economic progress and development.
