The mere possession effect of shareable digital coupons: The mediating role of anticipated self-enhancement

Shareable digital coupons have emerged as a new marketing strategy. Prior literature on shareable coupons assumes that shareable coupons can play a role only after they have been shared with others. Surprisingly, we theorize that shareable coupons can come into play as early as when consumers merely possess them, even before consumers share them with others, an effect that precedes the effect of the actual coupon sharing. In this research, we show that the mere possession of shareable digital coupons (not necessarily the actual sharing) is able to induce anticipated self-enhancement among consumers. Hence shareable digital coupons are more effective than non-shareable digital coupons, and the effect is most pronounced among consumers with high image concerns. The higher coupon effectiveness of shareable digital coupons is reflected in consumers' greater urge/intention to acquire the coupon, intention to revisit, willingness to spend, as well as in firm's sales increase when products are promoted with shareable instead of non-shareable digital coupons. Our work contributes to the literature on shareable coupons, the mere possession effects, anticipated self-enhancement, and other-rewarding promotions, and is of important managerial value given the ease with which the shareability feature can be added to coupons.     

人格类型对应激反应影响的实验研究(实验室应激源部分)

本研究以EPQ为依据选择高神经质和低神经质2组共24名被试,以有时间压力的心算和复杂辨别反应操作为紧张性刺激,在进行作业的同时记录被试的呼吸频率、呼吸流量、脉率、指端血管容积和皮肤电反应等五项生理指标,并检测尿内儿茶酚胺分泌量。通过对人格类型、作业成绩、作业难度主观评价、紧张性情绪体验,以及对尿内儿茶酚胺分泌量和五项生理指标的综合分析,以研究人格类型对应激反应影响的程度和途径。结果表明,在两组被试作业成绩无显著差异的情况下,在对作业难度主观评价和情绪体验的程度上,高神经质组高于低神经质组。在平静状态下,高神经质组去甲肾上腺素分泌量高于低神经质组;应激状态下,高神经质组的儿茶酚胺反应强度和变化幅度均明显高于低神经质组。高神经质组的五项生理指标均比低神经质组有较大的变化幅度。儿茶酚胺分泌量与脉率有明显的正相关。另外,通过与自然应激源部分的实验结果比较,发现实验室与现场应激的效果基本一致。     

8─11个月婴儿迂回行为发展特点与学习能力的研究

采用程序标准化的婴儿迂回行为测验,探讨了２４４名８－１１个月婴儿的迂回行为发展特点及学习能力。结果表明：（１）８－１１个月婴儿的迂回行为水平表现出随婴儿月龄的增长而提高的趋势。（２）８－１１个月的婴儿具有从反复尝试中学会迂回行为的可能性,其中９、１０个月的婴儿的学习可能性较大,而８个月婴儿的学习可能性较小。（３）８－１１个月婴儿的学习速度随月龄增大而提高。     

老年人高血压的临床特点及非药物治疗

随着世界人口老龄化,在65岁以上的老年人群中高血压患者占60％左右,有研究表明,高血压对于老年人的危害更为严重,老年高血压患者发生器官损害以及相关死亡的危险性显著增高.老年高血压患者有其特有的临床特点,同时在老年人群中收缩期高血压占很大的比例,降压效果差,因此老年高血压的治疗应考虑其特点,本文从老年人高血压的流行病学、定义、临床特点及非药物治疗等方面详细阐述了老年高血压的防治策略.     

反复胸闷胸痛伴心理精神障碍的诊疗进展

近年来,临床中关于反复胸闷胸痛患者的较高误诊率引起了广大医务工作者的重视,此类患者伴有的心理精神障碍往往被忽视,得不到合理的治疗,预后较差.本文主要讨论关于反复胸闷胸痛患者病因的鉴别、心理精神障碍引起胸闷胸痛的机制、胸闷胸痛与心理精神障碍的关系、“双心”医学诊疗模式以及反复胸闷胸痛的治疗进展,通过增强临床医生对“双心”医学的认识降低胸闷胸痛患者的误诊率、漏诊率,减少过度治疗,通过心血管医学和心理干预联合治疗,改善心血管疾病患者的预后、降低死亡率.     

PCI术前术后的心理障碍识别与处理

概述冠心病经皮冠状动脉介入治疗（PCI）术前术后患者合并心理障碍的较高发生率以及心理障碍对冠心病发生、发展及预后的影响,分析 PCI 术前术后患者出现焦虑抑郁等心理障碍的原因、产生机制及影响因素,强调心内科医生应及时识别 PCI 术前术后患者出现的心理障碍,并以“双心医学”方式对其进行心理精神医学及心血管专科医学治疗,同时对心血管专科医学治疗效果不明显的冠心病 PCI 患者,进行相关的鉴别诊断后也要进行心理精神医学的诊断和治疗,以便有利于 PCI 术患者的康复和预后,减少不必要的检查和治疗。     

Deliberate Numerical Discrepancy of Generation in the Genealogy of Matthew

In the genealogy of Matthew, there is a numerical ‘discrepancy’ between the actual totals of generations (fourteen, fourteen, and thirteen) recorded in Matthew 1:12-16 and the stated totals (fourteen, fourteen, and fourteen) in 1:17.

This paper argues that Matthew's genealogy is devised by inserting breaks based on the pattern and concept of Chronicles in order to convey the unique Matthean message. This argument will be defended by showing the similarities between Chronicles and Matthew: (1) Matthew follows the Chronicler by putting the genealogy at the beginning of the whole book as an introduction to convey the Matthean messages; (2) by combining concepts of kingship and priesthood; (3) by mentioning ‘the sons of Israel’ and ‘all Israel’; (4) by including Gentiles; (5) by using retribution theology; (6) by employing intensification in his chiastic genealogical structure; (7) Matthewâ..s omission of several kings is in line with the Chronicler's ideology of cultic-oriented kingship; (8) Matthew shares the Chronicler's point of view that Judah's deportation to Babylon does not invalidate Yahweh's promise for the Davidic kingdom. Thus, the apparent numerical ‘discrepancy’ is deliberately devised by the Matthean author, just as the Chronicler uses the numerical discrepancy to highlight his emphases in the genealogies.     

Partitioning and segregation of trace element Sn in a low-alloy steel

The partitioning of the trace element Sn into Cu-rich precipitates in a low-alloy pressure-vessel steel has been characterized using the three-dimensional atom probe (3DAP) technique. This investigation has revealed for the first time that the trace element Sn, present at only 0.007?at.% in the steel, partitions strongly to both small spherical precipitates (<4?nm in diameter) and to large non-spherical precipitates (largest dimension 10–50?nm) during thermal ageing. Sn was also seen to segregate strongly to the precipitate/matrix interface of a large Cu precipitate and particularly in the region where a dislocation appears to intersect the precipitate. The strong attraction of large solute atoms to special sites probably drives the interfacial segregation of Sn. This is consistent with the observation of stronger segregation of Sn to the interface of large precipitates than to the coherent interface of smaller precipitates.
