如何有效地引导个体“慷慨解囊”一直是理论和实践都关注的热点。基于道德基础理论和刻板印象内容模型,研究考察了在不同社会知觉(温暖型vs.能力型)的劝捐主体中,两种道德诉求方式(个体人道诉求vs.群体规范诉求)对劝捐效果的影响及其内在机制。3个实验的结果显示:温暖型(能力型)劝捐主体与个体人道诉求(群体规范诉求)更为契合,更有利于提升劝捐效果;温暖型劝捐主体进行个体人道诉求主要通过唤起个体的自我效能而提升劝捐效果,而能力型劝捐主体进行群体规范诉求则主要通过增强个体的反应效能而提升劝捐效果。

关键词：道德诉求温暖能力捐赠自我效能反应效能

支付渠道通常是捐赠信息中的必要元素。研究基于元认知推断理论,探讨了支付渠道数量因素(多个vs.单一)对个体捐赠的作用机制。通过6个实验和1个单文章元分析,结果发现:相比单一支付渠道,多个支付渠道反而会抑制个体捐赠的金额和意愿,感知商业化和道德怀疑连续中介以上效应。关键原因在于,多支付渠道在商业化背景下的频繁应用会使得人们持有"多支付渠道=商业化"的朴素信念。基于此,个体会对多个(vs.单一)支付渠道的捐赠信息产生感知商业化的元认知推断,进而怀疑捐赠对象的道德性,最后弱化捐赠意愿与行为。此外,朴素信念的可诊断性具有调节作用。具体而言,当"多支付渠道=商业化"朴素信念的可诊断性低时,个体将无法产生感知商业化的元认知推断过程,从而弱化多个(vs.单一)支付渠道对个体捐赠的负面作用。

负荷分解是智能电网的关键技术,对负荷预测、需求侧管理及电网安全有重要意义。传统负荷分解方法的准确率受限于负荷特征的维度、采样频率和负荷的稳定性。文中提出了基于因子隐马尔可夫模型的负荷分解方法,利用该模型对负荷进行建模,对Viterbi算法进行了扩展并求解负荷状态,进而基于整数规划实现对总负荷的最优分配。该方法对负荷数据的稳定性和采样频率不敏感,可适用于家居和工业电力用户。同时,深入研究了Viterbi算法求解最优状态与观测扰动之间的影响关系,并进一步得到最优状态对于当前观测的允许扰动范围,这对负荷分解最优状态的可靠性评估有重要意义。

目的探讨左卡尼汀辅助维持性血液透析治疗对尿毒症患者心脏功能及营养指标的影响。方法选取2018年3月~2019年10月我院肾内科尿毒症患者92例为研究对象,随机分为对照组与观察组各46例,对照组行维持性血液透析治疗,观察组在对照组基础上加左卡尼汀,对两组治疗前后心功能及营养指标、并发症发生率进行比较。结果治疗前,两组左心射血分数(LVEF)、左室舒张末期内径(LVEDD)、左室收缩末期内径(LVESD)比较,差异无统计学意义(P>0.05),治疗后,与同期对照组比较,观察组上述指标情况明显较好(P0.05),治疗后,与同期对照组比较,观察组上述指标情况明显较好(P<0.05);观察组并发症总发生率为4.35%,明显低于对照组的17.39%,差异有统计学意义(P<0.05)。结论左卡尼汀辅助维持性血液透析治疗可改善尿毒症患者心脏功能,调节机体营养指标,也能减少并发症发生,值得推广。
