The dark side of employee referral bonus programs : potential applicants’ awareness of a referral bonus and perceptions of organizational attractiveness

The purpose of this study is to examine the effects of potential applicants’ awareness of employees being rewarded for referrals on organizational attractiveness, based on credibility theory and the multiple inference model. In a first study (N=450), final-year students were less attracted to the organization when they knew employee referrals were rewarded, which was partially explained by lower credibility perceptions. Moreover, varying the specific characteristics of the referral bonus program (i.e., timing, size, type, recipient) did not improve potential applicants’ perceptions of credibility and attractiveness. A second study (N=127) replicated the negative effect of referral bonuses on organizational attractiveness and found that it could be explained by both potential applicants’ inferences about the referrer’s other-oriented motive and lower referrer credibility. Whether employees explicitly stated their referral reason was bonus-driven or not did not affect these results

Change blindness: eradication of gestalt strategies

Arrays of eight, texture-defined rectangles were used as stimuli in a one-shot change blindness (CB) task where there was a 50% chance that one rectangle would change orientation between two successive presentations separated by an interval. CB was eliminated by cueing the target rectangle in the first stimulus, reduced by cueing in the interval and unaffected by cueing in the second presentation. This supports the idea that a representation was formed that persisted through the interval before being 'overwritten' by the second presentation (Landman et al, 2003 Vision Research 43149–164]. Another possibility is that participants used some kind of grouping or Gestalt strategy. To test this we changed the spatial position of the rectangles in the second presentation by shifting them along imaginary spokes (by ±1 degree) emanating from the central fixation point. There was no significant difference seen in performance between this and the standard task [F(1,4)=2.565, p=0.185]. This may suggest two things: (i) Gestalt grouping is not used as a strategy in these tasks, and (ii) it gives further weight to the argument that objects may be stored and retrieved from a pre-attentional store during this task

Environmental Education in the Public Sphere: Comparing Practice with Psychosocial Determinants of Behavior and Societal Change

Environmental education of the general public is widely practiced by a variety of types of organizations. Dedicated environmental groups, nature centers, zoos, parks, and other entities work on issues ranging from local threats to air, water, and habitat to global problems such as climate change and deforestation. A great deal of those efforts focus largely on providing information and raising awareness. Behavioral research and change models, however, suggest other factors are important in order to effect change on an individual, regional, or societal level. An analysis of environmental education in practice, examining methods and materials in use, showed the degree to which there were alignments between the content and psychosocial determinants of change, as well as how actions related to change theories. This mixed-methods study of groups doing environmental education in the public sphere compared their practices with the factors shown to help predict pro-environmental behavior, why people change their actions and habits. Through this survey research and multiple case study, increased knowledge and understanding can help inform future efforts at change on critical local, national, and world environmental problems. It can also lead to further research into environmental education, using behavior and change theories

The effects of native advertising on audience perceptions of legacy and online news publishers

Extending research from Wojdynski and Evans, this experimental study replicates the challenges of effectively disclosing native advertising to readers and demonstrates a promising inoculation method that increases likelihood of recognition. Moreover, this quantitative research indicates that both legacy and online news publishers were evaluated less favorably for displaying native advertising. Attitudes toward the publisher and perceptions of its credibility declined for both, although online publishers suffered greater attitudinal damage than did legacy publishers who may benefit from their established reputation

Exploiting the robot kinematic redundancy for emotion conveyance to humans as a lower priority task

Current approaches do not allow robots to execute a task and simultaneously convey emotions to users using their body motions. This paper explores the capabilities of the Jacobian null space of a humanoid robot to convey emotions. A task priority formulation has been implemented in a Pepper robot which allows the specification of a primary task (waving gesture, transportation of an object, etc.) and exploits the kinematic redundancy of the robot to convey emotions to humans as a lower priority task. The emotions, defined by Mehrabian as points in the pleasure–arousal–dominance space, generate intermediate motion features (jerkiness, activity and gaze) that carry the emotional information. A map from this features to the joints of the robot is presented. A user study has been conducted in which emotional motions have been shown to 30 participants. The results show that happiness and sadness are very well conveyed to the user, calm is moderately well conveyed, and fear is not well conveyed. An analysis on the dependencies between the motion features and the emotions perceived by the participants shows that activity correlates positively with arousal, jerkiness is not perceived by the user, and gaze conveys dominance when activity is low. The results indicate a strong influence of the most energetic motions of the emotional task and point out new directions for further research. Overall, the results show that the null space approach can be regarded as a promising mean to convey emotions as a lower priority task.Postprint (author's final draft

Designing electronic collaborative learning environments

Electronic collaborative learning environments for learning and working are in vogue. Designers design them according to their own constructivist interpretations of what collaborative learning is and what it should achieve. Educators employ them with different educational approaches and in diverse situations to achieve different ends. Students use them, sometimes very enthusiastically, but often in a perfunctory way. Finally, researchers study them and—as is usually the case when apples and oranges are compared—find no conclusive evidence as to whether or not they work, where they do or do not work, when they do or do not work and, most importantly, why, they do or do not work. This contribution presents an affordance framework for such collaborative learning environments; an interaction design procedure for designing, developing, and implementing them; and an educational affordance approach to the use of tasks in those environments. It also presents the results of three projects dealing with these three issues

Tests of Graphic Visuals and Cigarette Package Warning Combinations: Implications for the Framework Convention on Tobacco Control

The World Health Organization recently adopted the Framework Convention on Tobacco Control, a groundbreaking public health treaty that will require that warning information in the form of text, pictures, or a combination of these two forms cover at least 30% of the front and back of cigarette packages. In three studies using smokers from the United States and Canada, the authors examine the effects of specific graphic visuals in the context of current U.S. verbal warnings. The findings indicate that including both graphic visual warnings, such as those used in Canada, and warning statements currently used in the United States can decrease the perceived attractiveness of the package and create higher levels of negative affect, such as fear or anxiety. The results also show that the addition of the specific visual warnings examined to the U.S. statements increases smokers’ perceived intentions of quitting smoking compared with warning statements alone. The authors offer implications for public policy and public health and provide suggestions for further research

The effects of perceived risk and responsibility on the acceptance of a Human Papillomavirus vaccine by college men

In the summer of 2006 the Food and Drug Administration approved a new vaccine to prevent four types of the Human Papillomavirus believed to cause the majority of genital warts and cervical cancer in women. Since that time the vaccine has experienced considerable uptake among women while it has also been met by some criticism. Current medical research aims to understand if the vaccine, which has been approved only for women, could be used to prevent HPV in men. Little empirical research has been conducted to understand whether or not men would be willing to receive a vaccine for a sexually transmitted infection that poses few serious health risks for them. This research investigates the level of acceptance among a sample of males at a large public university in New Hampshire as well as some of the possible predictors of men\u27s acceptance of a Human Papillomavirus vaccine. Specifically, men\u27s perceived risk for contracting the virus and its possible health consequences and their perceived sense of responsibility for sexual behavior will be examined as predictors of vaccine acceptance
