The effectiveness of post-16 pathways for gaining employment associated with undergraduate degree study

This article sets out to examine the effectiveness of five different post-16 study pathways and the impact that spending time away from education has on gaining employment associated with an undergraduate degree. It also explores advice and guidance for students looking at post-16 study options, higher education and employment. An initial online survey was used, followed by case studies to form a mixed-method approach. The findings suggest that a vocational pathway better prepares students for making decisions around employment and study in comparison to the more traditional A Level pathway. They also highlight that a period of one to four years after finishing post-16 study and starting undergraduate degree study is the most effective for students to gain employment associated with their undergraduate degree. Finally, it was found that most participants did not have positive experiences with advice and guidance regardless of their pathway.     

概念图结合思维导图对神经外科本科教学效果的影响

目的:探索概念图结合思维导图对神经外科本科的教学效果。方法:选取2014-2017年我院64名神经外科本科生为研究对象,按照随机数表分为2组,对照组采用传统理论课教学模式,观察组采用概念图结合思维导图教学模式。采用满意度评价量表对神经外科本科生教学效果满意情况进行调查,统计两组神经外科本科生期末成绩。结果:观察组教学效果满意率为90.63%,明显高于对照组教学效果满意率65.63%,数据对比具有统计学意义(P<0.05)。观察组期末成绩总分为(85.24±8.37)分,显著高于对照组期末成绩总分(67.70±4.76)分,数据对比具有统计学意义(P<0.05)。结论:概念图结合思维导图能够明显提高神经外科本科生教学效果满意度和期末成绩。

Three dimensions of equity of access to higher education

Concerns over equity of access to higher education are widespread, but there is significant disagreement over what should constitute a fair system. This article assesses diverse conceptualisations of equity and explores the ways in which they embody themselves in the policies of three systems, those of England, Brazil and Kenya. While showing significant disparities of income level and enrolment ratio, all three have made concerted efforts to expand higher education access, accompanied by increasing stratification in terms of the quality and prestige of institutions. Analysis of policy options and outcomes leads to a proposal of three principles for understanding equity of access: availability, accessibility and horizontality. The third of these principles addresses the little-acknowledged safeguard that disadvantaged students should not be confined to lower-quality institutions, while at the same time allowing for diversity of ethos and disciplinary focus.     

基于无线通信的静止式进相器系统设计

静止式进相器是专为大中型绕线式电机节能降耗设计的无功功率就地补偿装置。现有静止式进相器仅停留在单台电动机和单台静止式进相器的配套使用上,缺乏监控系统、历史数据无法保存。详细介绍了基于无线通信的静止式进相器系统设计,系统由静止式进相器控制子系统和主控子系统组成,使用无线通信模块实现静止式进相器和主控机的通信。主控子系统设计中,采用预约ALOHA实现主控子系统的多址通信。该系统经过实验和现场调试,其结果表明:静止式进相器补偿效果明显,实现系统无线通信功能,满足无线监测的设计要求。
