本研究基于成就情境下的情绪调节整合模型,采用问卷调查我国363名研究生在英文学术论文写作与发表过程中情绪调节策略的使用情况,并通过14个访谈探索影响情绪调节策略选择的因素。结果表明:研究生采取情境选择、情境修正、注意分配、认知改变、反应调节共五大类策略调节情绪,且不同策略使用频率差异鲜明;观念、情绪强度等内部因素与写作情境、人际关系等外部因素共同作用于策略选择,其中观念类因素起关键作用。以上结果拓宽了二语写作情绪调节研究范围,从情绪调节策略子类与学业情境特征两方面丰富了成就情境下的情绪调节整合模型,并揭示了情绪调节策略选择的内在机制。

目的分析男性酒精性肝硬化患者骨量异常发生率及其肝功能分级与骨代谢指标的相关性。方法该研究为回顾性研究。收集2017年3月至2023年7月于首都医科大学附属北京地坛医院住院的72例男性酒精性肝硬化患者为酒精性肝硬化组,根据年龄、BMI相匹配健康对照组40名,比较两组患者骨密度及骨质疏松发生率,比较不同Child-Pugh分级的酒精性肝硬化患者的骨密度及骨代谢指标血清骨钙素、总Ⅰ型胶原氨基端延长肽(TP1NP)、Ⅰ型胶原降解产物(β-CTX)和25羟维生素D[25-(OH)VD]等水平的差异及其相关性,采用有序多元logistic回归分析影响酒精性肝硬化患者Child-Pugh分级的骨代谢相关指标。结果酒精性肝硬化组72例患者中,骨量异常54例(75.0%),其中骨量减少21例(29.2%),骨质疏松33例(45.8%);对照组40名,骨量异常15例(37.5%),其中骨量减少9例(22.5%),骨质疏松6例(15.0%),两组患者发生骨量减少、骨质疏松的患者比例差异有统计学差异(χ^(2)=5.623、15.900,均P<0.05)。酒精性肝硬化组患者腰椎L1~L4椎体、股骨颈、转子间、股骨粗隆部位的骨密度水平均低于对照组(t=3.574、8.640、7.282、7.958、3.755、5.573、5.026,均P<0.05)。Child-Pugh C级酒精性肝硬化患者腰椎L1~L3、髋关节骨密度水平低于A级和B级患者(t=1.414、1.699、3.786、2.590,8.763、2.581、1.392、6.232,均P<0.05)。Child-Pugh C级患者25-(OH)VD水平低于A级和B级患者(t=3.969、2.911,P<0.05),血钙水平低于A级患者(t=3.627,P<0.05),TP1NP水平高于A级和B级患者(t=6.722、5.034,P<0.05)。Logistic回归分析显示结果显示,酒精性肝硬化患者TP1NP水平与Child-Pugh分级呈正向关联(β=2.186,P<0.05);25-(OH)VD水平与Child-Pugh分级呈负向关联(β=-0.767,P<0.05)。结论酒精性肝硬化患者骨量减少和骨质疏松症患病率显著升高,患者TP1NP水平、25-(OH)VD水平与Child-Pugh分级分别呈正向、呈负向关联。

With the development of the mobile communication and intelligent information technologies,the intelligent transportation systems driven by the sixth generation(6G) has many opportunities to achieve ultralow latency and higher data transmission rate. Nonetheless, it also faces the great challenges of spectral resource shortage and large-scale connection. To solve the above problems, non-orthogonal multiple access(NOMA) and cognitive radio(CR) technologies have been proposed. In this regard, we study the reliable and ergodic performance of CR-NOMA assisted intelligent transportation system networks in the presence of imperfect successive interference cancellation(SIC) and non-ideal channel state information. Specifically, the analytical expressions of the outage probability(OP) and ergodic sum rate(ESR) are derived through a string of calculations. In order to gain more insights, the asymptotic expressions for OP and ESR at high signal-to-noise ratio(SNR) regimes are discussed. We verify the accuracy of the analysis by Monte Carlo simulations, and the results show: i) Imperfect SIC and channel estimation errors(CEEs) have negative impacts on the OP and ESR; ii) The OP decreases with the SNR increasing until convergence to a fixed constant at high SNR regions; iii) The ESR increases with increasing SNR and there exists a ceiling in the high SNR region.

科学评估乡镇尺度生态系统服务价值(ESV)是乡村生态系统生产总值(GEP)定量核算以及镇域国土空间规划的重要前提。以四川丘陵区215个典型乡镇为研究对象,基于乡村生产-生活-生态用地(“三生用地”)分类系统和单位面积价值当量因子法,定量评估了乡镇尺度生态系统服务价值的空间分布及供需格局特征,并引入和弦图清晰表达了生态系统服务之间的权衡与协同关系。研究结果表明:(1)研究区乡村ESV空间分布存在明显的空间异质性和聚集特征,总体上南部和西南部丘陵区ESV高于北部和中部,中部地区ESV最低同时,ESV热点主要集中于西部和南部,冷点主要分布于中部和东北。(2)2015年,研究区ESV为62705元·hm^(-2),以调节服务为主(75.69%),其次为食物生产(9.07%)和生境服务(6.45%)。以农业生产用地为主导的乡村“三生用地”格局很大程度上导致了四川丘陵区ESV偏低,提升生态用地的数量与质量是改善区域生态系统服务的关键。对ESV的贡献率较高的“三生用地”类型为:乔木林地(41.25%)、河流湿地(22.95%)、水田(15.08%)、旱地(12.13)。(3)生态系统供给服务与其他三类服务均存在权衡关系,而调节、文化和生境服务之间为协同关系。随着人类对食物与水资源获取能力的增强,可能导致研究区大部分生态系统服务的下降。(4)研究区生态系统服务供需失衡较为明显,供需模式以L-H(39.98%)和H-L(35.92%)为主,呈现两极分化的趋势。同时,H-H模式“三生用地”结构合理,经济生态效益协调,是乡镇尺度可持续发展的代表模板。本文研究结果可为四川盆地乡村振兴空间布局优化以及长江上游生态环境保护提供科学依据。
