Group buying is a relatively new online consumption practice. Consumers negotiate product or service prices with businesses to obtain low prices or an increased number of products. This study investigates factors influencing online group‐buying intention from a conformity perspective. An online survey is used to sample 650 online group buyers in Taiwan. Structural Equation Modelling (SEM) is applied to examine the hypotheses within the theoretical framework. Analytical results indicate that social factors (online recommendations, media recommendations, and personal recommendations) positively affect social influence and online group‐buying intention. Individual factors (compliance and attention‐to‐social‐comparison‐information) positively affect social influence and conformity. Psychological factors (financial risk, performance risk, and social risk) negatively affect online group‐buying intention, and are positively correlated with social influence and conformity. Furthermore, social influence (informational influence and normative influence) are positively correlated with conformity and online group‐buying intention. Social influence and conformity are positively correlated with online group‐buying intention. Finally, implications of analytical findings are discussed. 相似文献

Little empirical investigation has been made on mini‐films, an innovative online marketing technique of branded entertainment. This study intends to gain a deeper understanding of the advertising effectiveness of mini‐films. Employing a narrative persuasion research approach, an online survey with hyperlinks to a variety of real mini‐films was conducted to test the aggregate persuasive effectiveness of this marketing innovation. The results demonstrated that narrative transportation has a major influence on the attitude toward the mini‐film; the mini‐film attitude fully mediates the effect of narrative transportation to brand attitude, and subsequently to purchase intention. Furthermore, conceptualized as a normal consumer characteristic, the influence of fantasy proneness on the persuasive mechanism of this online advertising genre has also been under study. Empirical evidence showed that fantasy proneness has a positive influence on narrative transportation. This study has made a contribution to academics and practitioners alike for future research into branded entertainment. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

This study examined factors associated with motivations to volunteer among older adults and how these motivations related to the subsequent volunteer experience. Focusing on one large national program, Experience Corps (EC), the authors interviewed 510 volunteers at the time they first volunteered for EC and again after one year of service. Eighty-seven percent were females, with ages ranging from 50 to 93 years. Volunteers were asked why they volunteered for this program; open-ended responses were coded into four types of motivations. Results showed that 33% reported altruistic motives; another 36% reported a mixture of altruistic and self-oriented motives, followed by self-oriented motives (16%) and practical features of the program (15%). Motivational type was regressed on demographic antecedents as well as volunteer history and receiving a stipend. Findings showed that African Americans and males were more likely to be motivated by altruism, whereas non-African Americans were more likely to report volunteering because of practical features of the program. Women were more likely than men to report being motivated by altruistic and self-benefit motives. Thus, recruitment messages regarding the altruistic nature of the volunteer work could be targeted toward older African Americans. Further, appealing to the possibility of doing good for others while doing good for oneself may appeal to older women. In regards to outcomes, motivation type did not affect the volunteer experience, suggesting that retaining volunteers may require different programmatic efforts than recruiting, such as providing supervision and recognizing volunteers’ contributions. 相似文献

The present study used a single‐task paradigm in which participants received guidance to focus more attention (waiting for someone) on the temporal intervals in the “waiting” condition and to stay relaxed in the control condition. The reported time was longer in the waiting condition than in the control condition. Functional near‐infrared spectroscopy was used to measure simultaneously the activation levels of the dorsolateral prefrontal cortex (DLPFC) for each condition. Greater oxyhemoglobin (oxy‐Hb) activation in the waiting condition was observed compared with the control condition, whilst deoxyhemoglobin data showed no difference between the two conditions. The gradual changes in oxy‐Hb in the DLPFC in increments of 100 ms yielded further insights into the role of this region in the “watched pot never boils” phenomenon. 相似文献

Drawing on theories of generalized exchange and the norm of indirect reciprocity, we conceptualize subordinates’ organizational citizenship behavior directed toward the organization (OCBO) and directed toward peers (OCBI) as antecedents of managerial trustworthy behavior and examine how managers’ affective trust in subordinates mediates this relationship. We also investigate the extent to which this mediation is moderated by the level of collectivism in a society. Data were collected from 741 managers and 2,111 subordinates in 18 countries representing all major cultural regions of the world. We find support for our hypothesized moderated mediation in that managers’ affective trust in subordinates mediates the relationships between both subordinates’ OCBO and managerial trustworthy behavior, and subordinates’ OCBI and managerial trustworthy behavior across the different countries studied. Further, managers’ affective trust in subordinates only mediates the relationships between both types of citizenship behavior and managerial trustworthy behavior when collectivism is low to medium but not when it is high. Implications for research on cross‐cultural psychology, trust, and organizational citizenship behavior are discussed. 相似文献

Comorbid depression is known to contribute to the maintenance of posttraumatic stress disorder (PTSD) including distressing intrusive trauma memories. It is theorised that depression is a risk factor for persistent PTSD through preventing optimal habituation of distress provoked by trauma memories and reminders, but the underlying cognitive mechanisms responsible are uncertain. The present study investigated trauma‐related rumination as a possible mediator for the effect of depression on trauma intrusions. Participants received a low mood induction or control procedure. Following viewing an analogue trauma film, frequency of film‐related intrusions and associated distress levels were measured and at 1‐week follow‐up. Between the two occasions, participants rated their levels of rumination about the film. Existing depression symptoms but not induced momentary sad mood predicted frequency of film intrusions and associated distress at 1‐week follow‐up. Some evidence was found that ruminative trauma processing mediated the relationship between baseline depressive symptoms and later intrusion frequency and associated distress. Future research is warranted to better understand the role of rumination in the depression–intrusion relationship, which may shed light on the clinical applicability of rumination‐targeted intervention for PTSD and comorbid depression. 相似文献

A critical skill in emergent writing is the developing ability to take the perspective of different readers; however, the precursors of this skill have not yet been identified. In this longitudinal study, 105 children (90 after attrition) were tested at 3 time points: pre-kindergarten (3–4 years old, n = 105), kindergarten (5 years old, n = 97), and Grade 1 (6–7 years old, n = 90). Theory of mind (ToM) in pre-kindergarten significantly predicted children’s awareness of a reader’s epistemic state when they dictated letters in both kindergarten and Grade 1 even after controlling for language (Peabody Picture Vocabulary Task [PPVT]) and inhibitory control. In addition, ToM in pre-kindergarten remained a significant predictor of reader awareness in Grade 1 after further controlling for reader awareness in kindergarten. There was little relationship between higher-order ToM tasks in kindergarten and reader awareness, but higher-order ToM in Grade 1 concurrently predicted reader awareness. Receptive vocabulary (PPVT) was significantly related to reader awareness at all time points, longitudinally and concurrently. This study has both theoretical implications for the relationship between ToM and emergent literacy and practical implications for the early identification and remediation of children at risk for later writing difficulties. 相似文献

In the current study, we examined the developmental course of the perception of non‐native tonal contrast. We tested 4, 6 and 12‐month‐old Dutch infants on their discrimination of Chinese low‐rising tone and low‐dipping tone using the visual fixation paradigm. The infants were tested in two conditions that differed in terms of degree of variability. The 4‐month‐olds did not show discrimination effect in either condition. The 6‐ and 12‐month‐old infants, however, discriminated the tones in both conditions. The improvement of perception might be the result of cognitive development carried over from learning the native phonology. Infants can become better listeners in general in the first year of life, as well as get cognitively better equipped in dealing with the variable input in speech in general.

The author examined what and how factors affect the employment status of Taiwanese college students with disabilities in the 1st year after graduation. The results demonstrated that (a) perceived acceptance by society and the employment market (ASEM) was the major factor affecting the employment status of individuals with disabilities (IWDs); (b) perceived ASEM influenced IWDs' psychological states, attitudes, and life‐planning styles, as well as their attitudes and strategies in job searching; and (c) the effect of IWDs' acceptance expectations on their employment development can be explained by the self‐fulfilling prophecy. 相似文献
