The Interplay of Psychology and Mathematics Education: From the Attraction of Psychology to the Discovery of the Social

It is a rather safe statement to claim that the social dimensions of the scientific process are accepted in a fair share of studies in the philosophy of science. It is a somewhat safe statement to claim that the social dimensions are now seen as an essential element in the understanding of what human cognition is and how it functions. But it would be a rather unsafe statement to claim that the social is fully accepted in the philosophy of mathematics. And we are not quite sure what kind of statement it is to claim that the social dimensions in theories of mathematics education are becoming more prominent, compared to the psychological dimensions. In our contribution we will focus, after a brief presentation of the above claims, on this particular domain to understand the successes and failures of the development of theories of mathematics education that focus on the social and not primarily on the psychological.     

Museum Assessment and FDH Technology: Towards a Global Approach

This paper presents a global approach for museum assessment. We conceptualise a museum as an entity which needs to be evaluated according to three well defined tasks: preservation, research and communication, and outcomes. We propose a methodology based on the determination of efficiency frontiers. This method uses a deterministic non parametric and non convex technology (Free Disposal Hull). We analyse technical efficiency, but also scale efficiency with a new restrictive scale approach. We present an ordering of museums into classes representing a level of performance with respect to the three required tasks. We illustrate our analysis using a three year database of museums from the French speaking region of Belgium.     

Introducing novel approaches for examining the variability of individuals’ physical activity

Tudor-Locke and colleagues previously assessed steps/day for 1 year. The aim of this study was to use this data set to introduce a novel approach for the investigation of whether individual’s physical activity exhibits periodicity fluctuating round a mean and, if so, the degree of fluctuation and whether the mean changes over time. Twenty-three participants wore a pedometer for 365 days, recorded steps/day and whether the day was a workday. Fourier transform of each participant’s daily steps data showed the physical activity had a periodicity of 7 days in half of the participants, matching the periodicity of the workday pattern. Activity level remained stable in half of the participants, decreased in ten participants and increased in two. In conclusion, the 7-day periodicity of activity in half of the participants and correspondence with the workday pattern suggest a social or environmental influence. The novel analytical approach introduced herein allows the determination of the periodicity of activity, the degree of variability in activity that is tolerated during day-to-day life and whether the activity level is stable. Results from the use of these methodologies in larger data sets may enable a more focused approach to the design of interventions that aim to increase activity.     

高校学生评教与师生情感关系研究——以边疆多民族地区A师范学院为例

学生评教作为学校评价教师的重要工具,自始受到学校管理部门的高度重视。但在强调师生情感关系的教学氛围中,学生评教的价值意义受到质疑。通过实证分析学生评教与师生情感之间的互动关系与相互影响,论证学生评教与师生情感的不相容性,提出学校应当容忍含有某种师生"情感"在内的学生评教偏误结果。

On the complementarity between online and offline music consumption: the case of free streaming

From a representative survey of 2,000 individuals, we study whether consumption of music through streaming services, like Spotify or YouTube, is a substitute or a complement to physical music consumption modes, such as CDs and live music. Controlling for the taste for music, various socio-demographic characteristics and the usual determinants of music consumption either offline (radio, TV, friends/relatives) or online (online recommendations, social networks), our results show that free music streaming (where the consumer does not possess the music but only has access to it) has no significant effect on CD sales and affects positively live music attendance, but only for national or international artists who are more likely to be available on streaming services.     

递增负荷运动对心电频谱分析的影响

为了了解递增负荷运动对心电频谱分析的影响,我们采用标准12导联引导心电信号,测试了30名大学生在递增负荷运动中的心电频谱图,所测得结果提示如下:频率成分能量比W1〔W1=E(100-1000Hz)/E(0-1000Hz)〕,W2〔W2=E(80-300Hz)/E(0-1000Hz)〕,在一、二级负荷运动后增大(P＜0.05),三级负荷后恢复到安静水平。
