实验史学:后现代主义在史学领域的诉求

效用、真实和时间构成了历史认识结构的基本要素 ,而历史认识史中的结构变迁经历了前现代 (从古代到 1 8世纪末职业化历史学产生之前 )、现代 (职业化历史学时期 ,即 1 8世纪末到 2 0世纪 70年代初 )和后现代 ( 2 0世纪 70年代后 )三个阶段 ,效用、真实、时间依次成为这三个阶段历史认识结构的中心。以时间为结构中心的后现代主义史学表现出历史主义的极端化 ,并进一步强调了时间、变化对于历史真实和历史意义的决定性作用 ,有鉴于此 ,历史叙述和阅读的私人化将促使历史学成为一种实验史学 ,即它不再是那种宣告历史真实的史学 ,而致力于在历史性情境下提供个体史学家认可的文本 ,并交由读者阅读、判断 ,随后通过该文本产生的效用来确认其是否真实。这样 ,任何一种史学实践都将是历史学家当下进行的一项追求历史真实的实验 ,而实验成功与否 ,完全取决于实验环境即阅读环境所提供的条件     

Towards a Framework for Evaluating the Research Performance of Chinese Double First-Class Universities

The study focuses on the research performance of Double First-Class (DFC) universities in China. A theoretical framework based on economic theory and the Analytic Hierarchy Process (AHP) method for a novel evaluation model is proposed. The model is performed on a sample of 41 participant DFC universities in China. Using data collected from these universities, it was found that there is no consistency between performance ranking, input ranking, and output ranking, with the best ranked universities far from the most efficient. These findings provide empirical evidence of DFC universities’ research performance situation and suggest strategies that the government can use to propel their sustainable development.     

Cut points of the Actigraph GT9X for moderate and vigorous intensity physical activity at four different wear locations

ABSTRACT

Accelerometer cut points are an important consideration for distinguishing the intensity of activity into categories such as moderate and vigorous. It is well-established in the literature that these cut points depend on a variety of factors, including age group, device, and wear location. The Actigraph GT9X is a newer model accelerometer that is used for physical activity research, but existing cut points for this device are limited since it is a newer device. Furthermore, there is not existing data on cut points for the GT9X at the ankle or foot locations, which offers some potential benefit for activities that do not involve arm and/or core motion. A total of N = 44 adults completed a four-stage treadmill protocol while wearing Actigraph GT9X sensors at four different locations: foot, ankle, wrist, and hip. Metabolic Equivalent of Task (MET) levels assessed by indirect calorimetry along with Receiver Operating Characteristic (ROC) curves were used to establish cut points for moderate and vigorous intensity for each wear location of the GT9X. Area under the ROC curves indicated high discrimination accuracy for each case.     

An Analytic Strategy to Assist Institutional Recruitment and Marketing Efforts

This article demonstrates how to fit a statistical model to historical data, test whether the model can accurately predict enrollment out-of-sample, and use the results to segment admitted students into groups so that different recruitment and marketing interventions can be applied. Conceptual and practical issues are discussed, as well as policy considerations.
