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。     

Asian American Women Sexual Assault Survivors’ Choice of Coping Strategies: The Role of Post-Assault Cognitive Responses

ABSTRACT

Even though approximately one in three Asian American (AA) and Pacific Islander women experience sexual assault victimization, there is a dearth of literature examining how AA women sexual assault survivors cope with this traumatic experience. This study examined AA female sexual assault survivors’ choice of coping strategies post-assault and how their cognitive responses toward sexual assault victimization (e.g., attributions of self-blame, perceived control over the recovery process) relate to their use of coping strategies. Using the AA subsets of two large community studies, a total of 64 AA women ages 18 to 58 with unwanted sexual experiences after the age of 14 years were included in the analyses. Results indicated that AA survivors used Acceptance and Self-Distraction the most to cope with sexual assault. In addition, those who perceived they had less control over their recovery process tended to use more maladaptive coping strategies, such as substance abuse and behavioral disengagement (e.g., giving up). The discussion includes clinical implications and recommendations for using language, modalities, and foci of interventions that are consistent with clients’ and their families’ worldviews (e.g., indirect inquiries, solution-focused).     

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.     

儿童早期数学认知能力的结构及其特点

从北京市10所幼儿园中选取234名3、4岁的儿童为被试,采用个别测查的方法对儿童早期数学认知能力的结构及其特点进行了考察。经验证性因素分析发现：(1)儿童早期数学认知能力的结构模型是合理的,可接受的,具有较好的构想效度,具体讲,数、计算、测量、空间／几何和模式认知能力五个维度共同解释着儿童早期的数学认知能力;(2)不同年龄儿童早期数学认知能力的结构具有稳定性,但是结构模型并不完全一致,某些项目的解释率有所不同;(3)男、女儿童早期数学认知能力的结构模型具有一致性。     

奖赏对海洛因成瘾者执行功能的影响机制

一些研究发现海洛因成瘾者奖赏失调表现为:对海洛因相关线索的注意偏向、渴求感增加,对金钱奖赏表现出"即时收益优先"的高风险决策模式和对长时收益的敏感性降低。另一些研究发现海洛因成瘾者的执行功能存在障碍。奖赏失调和执行功能障碍在成瘾物质使用的维持和复吸中起着重要作用。双重竞争模型认为奖赏和执行功能的交互作用决定着行为的结果,但是奖赏对海洛因成瘾者执行功能的影响机制还不清楚。因此,拟使用事件相关电位技术来考察海洛因相关线索和金钱奖赏对不同戒断期成瘾者执行功能的影响机制,短期(1~3个月)、长期(18个月以上)海洛因戒断者和健康对照组被比较。这不仅有助于构建完善的成瘾理论体系,还有助于确定临床戒断后复吸的风险因素和不同戒断期的治疗目标。
