道教学员16PF特征及其生活满意度研究

目的：了解道教学员的人格特征,及其生活满意度状况,通过对比为现代人生活提供借鉴．方法：采用16PF人格问卷和生活满意度量表（SWLS）对湖北武当山道教学院33名学员进行调查．结果：道教学员在16PF的9个维度均与大学生样本存在显著差异,具体表现为B（t=3．92 p〈0．00）、C（t=2．76 p〈0．01）、F（t=-3．19 p〈0．00）、G（t=2．67 p〈0．05）、H（t=2．80 p〈0．00）、L（t=-3．86 p〈0．00）、Q1（t=-4．58 p〈0．00）、Q2（t=-2．91 p〈0．00）、Q3（t=4．07 p〈0．00）;同时道教学员的生活满意度得分显著高于大学生样本（t=2．95,P〈0．01）;道教学员的积极情感显著高于大学生群体（t=3．55,P〈0．01）,其消极情感与大学生群体无显著差异．结论：道教学员人格特征在多个维度与一般大学生存在显著差异,他们生活满意度水平和积极情绪均显著高于后者。     

一种单片机实验装置升级改造的实现方案

目前单片机实验装置往往仍用综合技术指标低的51系列单片机作为控制核心,对此提出了一种低成本的系统改造方案,在不改变原有系统外围设备的情况下,通过一块电路板上的线路转换连接,令ATmega16与51系列单片机的管脚兼容,ATmega16即可替代51系列成为控制核心。这是单片机升级换代的一种新思路,对学校单片机实验装置的升级改造非常有意义。文章给出具体的改造方案以及一个典型实验的详细过程。     

Early gender test score gaps across OECD countries

The results reported in this paper contribute to the debate about gender skill gaps in at least three ways. First, we document the large differences in early gender gaps across developed countries using a large scale, modern, representative data source. Second, we show that countries with pro-female sorting, countries that place girls in classes with higher than average scores have smaller gender test score gaps, at least in math. Third, we show that the degree of academic tracking is correlated with observed gender gaps across developed countries.

“A tie is a tie? Gender and network positioning in life science inventor collaboration”

Collaborative relationships are an important anchor of innovative activity, and rates of collaboration in science are on the rise. This research addresses differences in men’s and women’s collaborative positioning and collaborator characteristics in science, and whether network influences on scientists’ future productivity may be contingent on gender. Utilizing co-inventor network relations that span thirty years of global life science patenting across sectors, geographic locations, and technological background, I present trends of men’s and women’s involvement in patenting and their collaborative characteristics across time. Amidst some network similarities, women are less likely to connect otherwise unconnected inventors (brokerage) and have greater status-asymmetries between themselves and their co-inventors. In multivariate models that include past and future activity, I find that some network benefits are contingent on gender. Men receive greater returns from network positioning for brokerage ties, and when collaborating with men. Women benefit from collaborating with women, and are more likely to collaborate with women, but both men and women collaborate with mostly men. I discuss the implications of these results for innovative growth, as well as for policies that support men’s and women’s career development.     

‘They get a qualification at the end of it,I think’: incidental workplace learning and technical education in England

Workplace learning is increasingly central to the international lifelong learning agenda but has made limited contributions to full-time vocational education in England during the last 30 years. A more central role is envisaged within the technical education proposed by the 2016 Sainsbury Review and Post-16 Skills Plan, with access to work placements dominating discussion of policy implementation. A multicase study of workplace learning among post-16 students in England on current ‘study programmes’ was mapped to four of the technical routes designated by the Sainsbury Review and Skills Plan, using documentary, observation and interview data. The study drew on theorisation of the workplace as the site of situated or incidental learning, whilst noting that its opportunities are differentially allocated according to organisational or personal differences, in ways that have particular implications for young people on placements. Whilst access to more advanced learning opportunities was secured through planned, collaborative approaches, reliance on incidental learning offered more routinised experiences to students less prepared for autonomous learning. The study indicates that questions of access, knowledge and pedagogy remain to be addressed if plans for ‘technical education’ in England are to provide meaningful learning opportunities and support transitions to fulfilling work.     

路易十六——我们应当重新认识

法国大革命被神话的外衣下有极其丑陋的一面,路易十六--这位无辜地成为了法国大革命牺牲品的法国国王,曾经为化解国家财政危机而励精图治,为支持法国大革命而拥护君主立宪,最后用自己的生命换来了法国大革命的进一步发展,这样一位国王,我们应当重新认识和评价。     

基于 3D FPN 的肺结节检测

肺癌早期发现与诊断对提高肺癌患者生存率至关重要。肺癌主要是由恶性肺结节造成的,通过肺结节早期检测与诊断能够及时发现病情,显著提高肺癌存活率。随着深度学习网络在医学辅助诊断领域应用的迅速发展,现已有很多深度网络被应用于肺结节检测。通过统计检测目标肺结节半径分布情况,发现大部分肺结节半径较小。因此,结合 CT 影像数据的三维特性,提出使用 3D FPN 进行单阶段肺结节检测,能够解决肺小结节检测效果不佳的问题。在公用肺结节数据集 LUNA16 上验证了网络的有效性,CPM 值达到 0.893 2,相比其它肺结节检测网络,检测效果提高了 2%。
