Politicising the ‘personal’: the resistant potential of creative pedagogies in teaching and learning ‘sensitive’ issues

Drawing upon student narratives gleaned through qualitative interviews, this paper argues that teaching and learning ‘sensitive’ issues surrounding gender and sexualities through ‘creative’ pedagogies can be a mode of resistance against the reproduction of problematic social discourses, and to the negative impacts of neoliberalism on student’s learning within higher education. The findings point to the importance of speaking about sensitive issues; the value of creative approaches for enhancing learning; and that together these can enable students to articulate an agenda for social change. Students saw the ‘personal as political’ – of sharing personal journeys around sensitive issues as important. They further spoke of ‘apathy’ in an neoliberal era of student ‘consumers’ and how this could curtail ‘creative’ teaching and jeopardise learning. Overall, it is argued that creative approaches to teaching and learning sensitive issues can invoke a resistant potentiality which exposes the ‘hidden injuries’ (Gill, 2010) of the neoliberal university.     

基于敏感信息分类的网络信息安全编程方法优化

在对网络信息进行安全编程的过程中容易出现敏感信息与正常信息混淆的情况,导致传统的网络信息安全编程方法由于存在一定的模糊性,无法有效实现网络信息安全编程,提出一种基于敏感信息分类的网络信息安全编程方法,分别求出两个模糊集之间的语义相关度,获取上述语义相关度中最大者,将敏感信息归并在一起,形成文本集合的几个子集,各子集的元素均具有敏感特征。信源经一系列变换后,最后获取经处理后的网络信息,对原始信源消息进行求解,完成信宿的译码操作。仿真实验结果表明,所提方法具有很高的可行性。     

Elevated high sensitive C-reactive protein and apelin levels after percutaneous coronary intervention and drug-eluting stent implantation

Objective:Percutaneous coronary intervention(PCI) triggers an acute inflammatory response,while sirolimus is known to have anti-inflammatory properties;the inflammatory system response to PCI after sirolimus-eluting stent placement remains unclear.The purpose of this study is to determine the changes in high sensitive C-reactive protein(hs-CRP) and apelin after PCI procedure and drug-eluting stent implantation in patients with and without reduced left ventricular systolic function.Methods:Forty-eight consecutive patients undergoing PCI at the Beijing Anzhen Hospital between July and September 2006 were recruited.Sirolimus-eluting stents were employed in all patients.Blood samples were drawn immediately before and 24 h after the procedure.Plasma hs-CRP and apelin levels were determined by enzyme immunoassay.Results:Paired t-test revealed a significant increase in both hs-CRP and apelin post-procedure(P=0.006 and P0.0001,respectively).Patients with reduced left ventricular ejection fraction(LVEF) had significantly lower baseline apelin levels compared to those with normal ventricular function [(46.8±10.8) vs.(72.0±8.4) pg/ml,P0.001].However,apelin increased to a level similar to the level of those with normal left ventricular systolic function 24 h after the PCI procedure [(86.7±11.6) vs.(85.1±6.1) pg/ml,P=0.72].Conclusions:hs-CRP and apelin levels increased after PCI and sirolimus-eluting stent implantation.Patients with impaired left ventricular systolic function had significantly lower baseline apelin levels,which increased significantly after PCI.

广州市天河区居民健身消费力影响因素调查与分析

通过对广州市天河区居民的随机抽样调查,对其月健身消费支出、是否参与过健身消费与相关影响因素关系进行研究。结果发现,主体因素、客体因素和环境因素对天河区居民参与健身消费的影响度有依次增大的趋势,但无显著性差异(P>0.05)。健身场所环境好、器材好、享受健身消费、朋友的支持等因素对月健身消费支出影响度较大;而健身服务、健身意外、健身效果以及专业人员的指导是影响受调查者是否参与健身消费的重要因素。其它消费方式更具吸引力和专业人员指导不够两个因素既是影响健身消费的主要因素,同时也是敏感因素。
