Reforming China’s polar science and technology system

ABSTRACT

Along with its modernization process, China has developed many interests in polar ecology and has connected the significance of the Antarctic and Arctic to its national interests. We present an in-depth analysis and assessment of the state of the art of China’s polar research from following points of view, mechanism of policy making on polar affairs, science diplomacy and polar governance, on-spot research expedition management, allocation of scientific funds, forming polar scientific team, especially on the management system of CHINARE. From an integrated perspective of social and natural sciences, we present a vision for future reform and development of polar affairs of China: to establish a macro and long term policy for the polar regions, to promote and establish a government-led, diversified polar scientific management system, to establish a reasonable and rule based evaluation system, to train, stabilize and expand polar scientific research teams, and to attract and encourage talents for polar science communication.     

A third road to the past? Historical scholarship in the age of big data

Is a third passage to the past possible, beyond Elton's and Fogel's two roads of narrative history and scientific/quantitative history? One that would combine narrative history's focus on the event, on individuals and their actions, at a particular time and place, to scientific/quantitative history's emphasis on explicit behavioral models based on social-science theories? That is the question this article addresses. It illustrates a computer-assisted methodology for the study of narrative—quantitative narrative analysis (QNA)—that does just that. Based on the 5 Ws + H of narrative—Who, What, When, Where, Why, and How—QNA quantifies events without losing the event itself, without losing people behind numbers, diachronic time behind synchronic statistical coefficients. When used in conjunction with dynamic and interactive data visualization tools (and new natural language processing tools), QNA may provide a third unforeseen road to the past.
