Belief in a Just World: Consumer Intentions and Behaviors Toward Ethical Products
Although consumers report positive attitudes toward ethical goods, their intentions and behaviors often do not follow suit. Just-world theory highlights the conditions under which consumers are most likely to prefer fair-trade products. This theory proposes that people are motivated to construe the world as a just place where people get what they deserve. In the current research, when people are confronted with high levels of injustice (communicated need is high) and avenues for justice restoration seem uncertain or unavailable, assisting others by supporting fair trade decreases. However, highlighting how injustice can be redressed through purchases enhances fair-trade support under conditions of high need. The effects are moderated by justice sensitivity factors, such as just-world beliefs and whether the product type (indulgence vs. necessity) makes the injustice of consumer privilege salient. The results suggest that communicating high need when requesting consumer prosocial actions can sometimes backfire. Marketers employing high need appeals should heighten perceptions of justice restoration potential and activate fairness-related thoughts through product positioning to encourage fair-trade purchases
Do we really need Confidence Intervals in the new statistics?
This paper compares the use of confidence intervals (CIs) and a sensitivity analysis called the number needed to disturb (NNTD), in the analysis of research findings expressed as ‘effect’ sizes. Using 1,000 simulations of randomised trials with up to 1,000 cases in each, the paper shows that both approaches are very similar in outcomes, and each one is highly predictable from the other. CIs are supposed to be a measure of likelihood or uncertainty in the results, showing a range of possible effect sizes that could have been produced by random sampling variation alone. NNTD is supposed to be a measure of the robustness of the effect size to any variation, including that produced by missing data. Given that they are largely equivalent and interchangeable under the conditions tested here, the paper suggests that both are really measures of robustness. It concludes that NNTD is to be preferred because it requires many fewer assumptions, is more tolerant of missing data, is easier to explain, and directly addresses the key question of whether the underlying effect size is zero or not
Social Media & Teacher Professional Development
The idea of social media’s existing application and future potential for professional development drives a growing subset of academic research. As we encourage preservice and inservice teachers to engage in these platforms to hone or refine their classroom practice, a number of questions emerge: How do we assess participation in these spaces? What uses in particular should we recommend? Further, the very notion of conducting research in these spaces also poses interesting questions. From methodologies to frameworks, commonly accepted practices help shape the future of the field. Lastly, the issue of privacy and policy poses perhaps the most significant area for attention. The intent of this panel discussion is generate conversation on how future research and application on social media usage and research might evolve over time
Damaging real lives through obstinacy: re-emphasising why significance testing is wrong
This paper reminds readers of the absurdity of statistical significance testing, despite its continued widespread use as a supposed method for analysing numeric data. There have been complaints about the poor quality of research employing significance tests for a hundred years, and repeated calls for researchers to stop using and reporting them. There have even been attempted bans. Many thousands of papers have now been written, in all areas of research, explaining why significance tests do not work. There are too many for all to be cited here. This paper summarises the logical problems as described in over 100 of these prior pieces. It then presents a series of demonstrations showing that significance tests do not work in practice. In fact, they are more likely to produce the wrong answer than a right one. The confused use of significance testing has practical and damaging consequences for people's lives. Ending the use of significance tests is a pressing ethical issue for research. Anyone knowing the problems, as described over one hundred years, who continues to teach, use or publish significance tests is acting unethically, and knowingly risking the damage that ensues

When Flexibility Is Stable: Implicit Long-Term Shaping of Olfactory Preferences
Preferences are traditionally assumed to be stable. However, empirical evidence such as preference modulation following choices calls this assumption into question. The evolution of such postchoice preference over long time spans, even when choices have been explicitly forgotten, has so far not been studied. In two experiments, we investigated this question by using a variant of the free choice paradigm: In a first session, participants evaluated the pleasantness of a number of odors. We then formed pairs of similarly rated odors, and asked participants to choose their favorite, for each pair. Participants were then presented with all odors again, and asked for another pleasantness rating. In a second session 1 week later, a third pleasantness rating was obtained, and participants were again asked to choose between the same options. Results suggested postchoice preference modulation immediately and 1 week after choice for both chosen and rejected options, even when choices were not explicitly remembered. A third experiment, using another paradigm, confirmed that choice can have a modulatory impact on preferences, and that this modulation can be long-lasting. Taken together, these findings suggest that although preferences appear to be flexible because they are modulated by choices, this modulation also appears to be stable over time and even without explicit recollection of the choice. These results bring a new argument to the idea that postchoice preference modulation could rely on implicit mechanisms, and are consistent with the recent proposal that cognitive dissonance reduction could to some extent be implicit
Physical attractiveness as a mediator of the impact of early pubertal changes for girls
The present study examined the effects of early pubertal development and physical attractiveness on the popularity, body image, and self-esteem of over 200 sixth-grade girls. Two rival hypotheses were explored. The first suggests that physically attractive girls, because of their more favorable social environment, will exhibit fewer psychosocial difficulties than unattractive girls during pubertal development. The second hypothesis argues that attractive girls will exhibit greater difficulty during pubertal transition because their self-image is more intimately connected with their physical appearance. Although there were no significant interactions between attractiveness and pubertal development for either popularity or body image, the second hypothesis was supported with respect to self-esteem. Specifically, developing attractive girls exhibited lower self-esteem than their unattractive counterparts. The results are discussed in terms of the relative vulnerability to bodily changes of girls differing in physical attractiveness.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45265/1/10964_2005_Article_BF02088640.pd
On the Importance of Complaint Handling Design : A Multi-Level Analysis of the Impact in Specific Complaint Situations
Given the large investments required for high-quality complaint handling design,
managers need practical guidance in understanding its actual importance for their
particular company. However, while prior research emphasizes the general relevance
of complaint handling design, it fails to provide a more differentiated perspective on
this interesting issue. This study, which is based on an integrative multi-level
framework and a dyadic dataset, addresses this important gap in research. Results
indicate that the impact of a company’s complaint handling design varies significantly
depending on the characteristics of the complaining customers with which the firm has
to deal. Further, this paper shows that, contingent on these characteristics, a company’s
complaint handling design can shape complainants’ fairness perceptions either
considerably or only slightly. Overall, findings suggest that companies should apply
an adaptive approach to complaint handling to avoid misallocation of attention,
energy, and resources
