新春
药物评价研究 , 2015, DOI: 10.7501/j.issn.1674-6376.2015.06.018
Abstract: 目的 观察分析米索前列醇联合米司非酮治疗妊娠10~16 周稽留流产的疗效及安全性。方法 选择2010 年1 月―2013 年6 月在秦皇岛经济技术开发区医院妇产科治疗的孕10~16 周稽留流产患者256 例和要求终止妊娠的孕10~16 周患者139 例,将稽留流产患者随机分为A 组(给予米索前列醇)和B 组(给予米索前列醇和米司非酮),每组128 例;终止妊娠患者为C 组(给予米索前列醇),观察3 组治疗效果和不良反应情况。结果 A、B、C 3 组完全流产率分别为64.06%(82/128)、87.50%(112/128)、66.19%(92/139),B 组与其他两组差异有统计学意义(χ2 值=21.450,P< 0.05);A 组与C 组比较,差异无统计学意义。B 组患者平均阴道出血量为(102.56±54.32)mL,明显高于其他两组的(80.24±48.97)mL 和(54.75±34.87)mL,差异有统计学意义(P< 0.05);A、B、C 3 组患者平均排胎时间分别为(12.78±4.89)、(13.59±5.87)、(13.47±4.21)h,差异无统计学意义;A、B、C 3 组患者不良反应率分别为50.78%、54.69%和44.60%,差异无统计学意义,3 组患者均未经特殊处理,症状自行缓解消失,无严重并发症出现。结论 米索前列醇联合米司非酮治疗妊娠10~16 周稽留流产能提高完全流产率,排胎时间与终止妊娠患者相当,且未增加不良反应的发生率。米索前列醇联合米司非酮治疗患者阴道出血量有所增多,但在正常范围内。
家族企业传承期抑制了研发投入吗?——基于家族企业多重目标的调节效应
,新春
- , 2018,
Abstract: 家族企业面临着代际传承与创新转型的双重挑战.传承期研发投入如何变化是一个重要但仍具争议性的问题.本文将传承期分为父子共治与二代自治两阶段,从社会认同理论出发,基于2007—2015年传承期家族上市公司数据,探究研发投入的阶段差异.研究发现:相较于父子共治阶段,二代自治阶段更有利于研发投入的提升,并且这种阶段差异受两种相反力量的调节,控制目标的实现放大了这种差异,而经济目标的实现则抑制了这种差异.本研究揭示了家族企业传承期研发投入的阶段差异,但这种差异受到家族企业多重目标的调节,有助于深化对传承期研发投入问题的认识.
含空位晶体的衍射动力学
张喜燕,新春,贾冲
重庆大学学报 , 2008, DOI: 10.11835/j.issn.1000-582X.2008.02.006
Abstract: 空位会对材料相变、晶体生长、原子扩散等结构演变过程产生重要影响,并对材料的物理、力学性能产生重要影响,但是如何对空位进行表征,从而捕捉材料内部的空位并直接观察其形态特点一直很困难.笔者用散射矩阵法研究了含空位晶体的衍射强度,把空位考虑成刚体球,并且引入"真空体"去反映空位对晶体的衍射影响,计算了晶体的衍射强度随空位位置的变化,并对一些影响因素进行了讨论.
生活事件对情感和行为的影响:理论比较与启示
陈红敏,,新春
心理科学进展 , 2014,
Abstract: ?关于生活事件对个体情感反应和行为选择的影响研究,均试图从不同生活事件和行为决策关系的角度对个体的影响机制进行解释,但不同理论之间存在争议。行为/经济理论认为人“绝对理性”,而平均/累加模型、峰-终定律和心理账户认为人“有限理性”。详细比较发现,各理论在解释的视角、研究方法的选择、生活事件的界定等方面均有不同。未来研究应围绕理论之间的鉴别与整合、生活事件属性与个体属性之间的交互影响以及研究方法的多元化等方面展开。

情感强度不同负性生活事件对个体情感反应和行为选择的影响
陈红敏,,新春
- , 2016,
Abstract: 摘要: 采用系列实验方法探讨不同情感强度负性生活事件对个体情感反应和行为选择的影响。结果发现:(1)复合生活事件(1高负性+1低负性)为异类时,个体对复合事件的负性感受比单独1高负性事件更低,选择经历前者,出现平均效应;(2)复合生活事件为同类时,其负性感受比单独1高负性事件更高,选择经历后者,出现累加效应;(3)复合事件有明显的时间特点时,其情感和行为选择受事件发生时间影响,符合峰-终定律。结论:人们对负性生活事件的加工受其特点的影响,加工方式不同。
Abstract: Regarding the impact of life events on individual’s affective reactions and behavior options, there is a big dispute among existing studies. It is generally believed that more negative events were worse. But studies have inconsistent conclusions: more negative events were better when events have different affective intensities (Seta, Haire, & Seta, 2008).Thus, the affective intensity of negative life events may be a crucial variable. In addition, no satisfactory explanations were given by averaging and summation model, peak-end rule and mental accounting models. The main purpose of this study is to explore the impact of different intensity negative life events on individual’s affective reactions and behavior options, then find its internal processing mechanism and establish a satisfactory theory explanation. 144 college students participated in three experiments. The study applied research paradigm from Seta, Haire, & Seta (2008), the experimental materials for Chinese college students' negative life events. Participants were told that the experimenter was interested in their reactions to different events. After that, they were given packets that contained the experimental manipulations. Participants indicated how negative they felt after thinking about the events that happened to them on a 101-point scale where “0” indicated “low negative” and “100” indicated “super extremely negative.” And, they also were asked to choose between the two options (the highly negative event versus the highly negative plus mildly positive one) by placing a circle around the letter (either A or B) that appeared in front of each option. Order of options and event presentations were counterbalanced. The results showed that individual would use different processing mode to the negative life events of different attribution, which was shown in the difference of affective reactions and behavior options. Experiment 1 found that participants had a more intense negative affective reaction when they were exposed to a highly negative life experience rather than exposed to two negative events: a highly negative and a mildly negative life event. This supports averaging effect. There were no significant order effects. The lack of order effects in this experiment demonstrates that averaging effects can be obtained over and above sequence

Abstract: 摘要: 3个实验探讨情感强度不同正性生活事件对个体情感和行为反应的影响。发现:(1)面对复合正性生活事件(1高正+1低正),个体会感觉比面对1个单独的高正性情感强度事件的正性感受更低,出现平均效应,2个正性生活事件不如1个好;进一步研究发现:(2)当复合正性生活事件为异类时,出现平均效应;当事件为同类时,出现累加效应;(3)当复合正性生活事件有明显的时间特点时,个体加工符合峰-终定律的解释。
Abstract: Positive life events bring the cheerful affection to people, which is beneficial for people's physical and mental health. It is generally believed that more positive events are better. But studies have inconsistent conclusions: more positive events were worse when these events had different affective intensities (Seta, Haire, & Seta, 2008). This study adopts the method of experimental research, through a series of experiments to discuss how the different characteristics of positive life events affect individual process, and try to reveal the influencing mechanism and rule of positive life events on college students. This study applied the experimental paradigm from Seta, Haire, & Seta (2008), the experimental materials for Chinese college students' positive life events. 144 college students participated in three experiments. First of all, the 10 groups of experimental materials were selected from questionnaire survey on Chinese college students who experienced positive life events. Subjects rated the positive life events from - 10 (very negative) to + 10 (very positive), the high positive event was rated at + 6.5 or so, low positive event was rated at + 3.5 or so. Then, in the normal experiments, the participants were told that the experimenter was interested in their reactions to different events (one highly positive event condition and a mixed condition that contained two events—a highly positive and a mildly positive one). They were then given materials that contained the experimental manipulations. In the mixed condition, the order of the positive stimuli was counterbalanced using a Latin-Square design. After reading the information, participants were asked how positive thinking about the event(s) made them feel on a 101-point scale where 0 represented ‘‘not at all’’ and 100 represented ‘‘extremely positive’’. And participants were asked to make a choice between two events which one is prefer to experience in life. The results found that the processing of different positive life events is a discriminant model of processing in general. Experiment 1 found that participants had a more intense positive affective reaction when they were exposed to a highly positive life experience rather than exposed to two positive events(a highly positive and a mildly positive life event), which supports averaging effect. There were no significant order
