The Role of Relational Uncertainty in Topic Avoidance among Couples with Depression

To address a key gap in theorizing and research, we consider relational uncertainty as an explanation for why individuals experiencing depressive symptoms may be reluctant to talk about sensitive issues. We report closed-ended online survey data from 126 romantic couples in which one or both partners had been professionally diagnosed with depression. Results indicated that relational uncertainty mediated the positive association between depressive symptoms and topic avoidance. Partner effects from men to women also emerged. These findings are valuable for identifying relational uncertainty as a mechanism that may explain people's unwillingness to discuss challenging topics when they are experiencing depressive symptoms.     

不确定判断与阅读多选题的猜测策略

本研究应用不确定判断理论,采用有声思维的方法,探讨受试在不确定的情况下如何猜测多项选择阅读题。研究发现受试采用了代表性、可得性、锚定与调整等搜索性策略。而锚定与调整策略最为有效,常被用作"锚"去调整猜测的有背景知识、常识、逻辑推理、应试型知识等。这一发现对命题有启示,有助于改善试题质量,降低猜测的命中率,提高考试效度。     

不同类型区域减排的技术经济路径研究

减排是应对气候问题、缓解资源环境困境、实现经济社会可持续发展行之有效的技术经济手段,其路径选择因不同类型区域的客观条件而异。关注区域减排应立足资源节约型、环境友好型农牧业,大力发展清洁、节水和节投农牧业;困难区域减排较为现实的选择是优化资源开采利用,调整资源产品结构;挑战区域减排的最佳途径是开发利用新能源,实行产业结构转型与升级;理想区域减排的重心在于加强低碳产品供给和引导低碳消费模式。

中国煤炭需求波动规律研究

把握煤炭需求波动规律对于预测煤炭需求趋势和保障煤炭应急供应至关重要.本文运用小波分析等方法对我国煤炭需求波动状况进行了测度.针对年度尺度的数据,小波分析得出煤炭需求波动的主周期为6年,HP滤波方法得出波动周期平均为5.9年,BP滤波法得出的主周期为4.8年.综合比较可看出,煤炭需求波动主周期为5～6年,并且比经济波动滞后1～2年,且存在时隔30多年的大突变点.月度尺度的数据研究显示煤炭需求存在3～6个月的季节波动.基于上述分析,认为煤炭需求波动由周期长度为30～40年的长波、5～6年的中波、3～6个月的短波组合而成,其中最主要的是中波.通过进一步分析,指出导致煤炭需求波动长波、中波、短波产生的主要原因分别为国家的重大经济转折、正常的经济周期性波动、电力需求季节性波动.     

To Hope or to Know: Coping with Uncertainty and Ambivalence in Women's Magazine Breast Cancer Articles

Breast cancer is one of the most feared diseases in contemporary Western society. Popular women's magazines are important sources of information about and orientation to the disease. The current study applies problematic integration theory in an interpretive analysis of all breast cancer articles appearing in five top-circulating women's magazines between 1997 and 2002. In so doing, the study illuminates two major challenges (uncertainty and ambivalence) and several imperfect approaches to coping constructed in this discourse (simplification, information-seeking/provision, affect management, trusting intuition, sustaining hope, and metaphoric reframing). These results have several clear and important practical implications and highlight a major and largely untried direction for future research.     

Gray cases of child abuse: Investigating factors associated with uncertainty

Research in child abuse pediatrics has advanced clinicians’ abilities to discriminate abusive from accidental injuries. Less attention, however, has been paid to cases with uncertain diagnoses. These uncertain cases – the “gray” cases between decisions of abuse and not abuse – represent a meaningful challenge in the practice of child abuse pediatricians. In this study, we describe a series of gray cases, representing 17% of 134 consecutive children who were hospitalized at a single pediatric hospital and referred to a child abuse pediatrician for concerns of possible abuse. Gray cases were defined by scores of 3, 4, or 5 on a 7-point clinical judgment scale of the likelihood of abuse. We evaluated details of the case presentation, including incident history, patient medical and developmental histories, family social histories, medical studies, and injuries from the medical record and sought to identify unique and shared characteristics compared with abuse and accidental cases. Overall, the gray cases had incident histories that were ambiguous, medical and social histories that were more similar to abuse cases, and injuries that were similar to accidental injuries. Thus, the lack of clarity in these cases was not attributable to any single element of the incident, history, or injury. Gray cases represent a clinical challenge in child abuse pediatrics and deserve continued attention in research.     

洛仑兹-狄拉克方程的新降阶方法

针对洛仑兹-狄拉克方程的新降阶方法在氢原子中的适用尺度问题,通过数值计算二维氢原子来比较新降阶方法和原方法在2费米到100 000费米区间内的差异,两种降阶方法在远离质子的区域计算结果基本一致,而在靠近质子几费米区域内,新方法的结果和原方法相差较大.表明在氢原子外围区域,两种方法对于洛仑兹-狄拉克方程来说都是适用的;研究电子在更近区域内的运动行为,新降阶方法更加准确.新降阶方法计算的表达式比原降阶方法复杂,所以关于氢原子,有时联合使用两种降阶方法也会是一个不错的考量.
