Social media and corporate reputation during crises: the viability of video-sharing websites for providing counter-messages to traditional broadcast news

Exemplification, or the use of highly emotional and arousing messages to elicit responses based on impression formation, has been shown to influence perceptions of events, individuals, and organizations. News coverage concerning the use of lean finely textured beef (LFTB) is one such example, and anecdotal evidence suggests that this coverage may have had a negative impact on public perception of the manufacturers producing LFTB. The current study examined the use of social media (specifically video-sharing sites) as a means of combating the negative effects of exemplars concerning LFTB. Respondents reported their perceptions of threat severity, susceptibility, behavioral intentions to avoid LFTB, and perceptions of organizational trust and reputation associated with the manufacturer. The findings are consistent with exemplification theory and indicate that message ordering can influence exemplification effects. Results are discussed in terms of implications for public relations and risk communication.     

Tweeting Fast Matters,But Only if I Think About It: Information Updates on Social Media

Social media have emerged as increasingly important sources through which the public seeks information concerning crises or risks. Despite this increased dependence, little is known about the psychological processes associated with perceptions of source credibility or the desire to seek additional information related to the risk. The current study investigates the role of speed of updates in credibility perceptions and information seeking using Twitter. The results do not provide evidence of a direct relationship between update speed and the outcomes under consideration. They do, however, consistently support a mediation model in which cognitive elaboration mediates the relationship between update speed and perceptions of sender competence, goodwill, trustworthiness, and reader (follower/audience/rater/target) desire for additional information. These findings are discussed in terms of their implications and applied use.     

Presence,Sex, and Bad News: Exploring the Responses of Men and Women to Tragic News Stories in Varying Media

This study explores the interplay of sex, presence, and enjoyment of nonfictional tragic news content; an experiment was conducted in which participants viewed a news story about Hurricane Katrina's devastation to the Gulf Coast on a standard definition television, high definition television, or a video iPod. The results indicate that women reported more sadness regardless of condition, though they seemed especially moved in the iPod condition. Women also reported more information seeking, and reported highest levels of presence in the iPod condition. The results are discussed both in terms of implications for crisis message practitioners, and in terms of what the results may mean for our understanding of the enjoyment of tragedy.     

Four-year longitudinal impact evaluation of the Action for Children UK Neglect Project: Outcomes for the children,families, Action for Children,and the UK

Neglect has a devastating impact on children and is the most pervasive form of child maltreatment in the United Kingdom. The study purpose was to establish outcomes for neglected children following structured assessment and intervention to ascertain what worked and why it worked.     

A method to integrate patterned electrospun fibers with microfluidic systems to generate complex microenvironments for cell culture applications

The properties of a cell’s microenvironment are one of the main driving forces in cellular fate processes and phenotype expression invivo. The ability to create controlled cell microenvironments invitro becomes increasingly important for studying or controlling phenotype expression in tissue engineering and drug discovery applications. This includes the capability to modify material surface properties within well-defined liquid environments in cell culture systems. One successful approach to mimic extra cellular matrix is with porous electrospun polymer fiber scaffolds, while microfluidic networks have been shown to efficiently generate spatially and temporally defined liquid microenvironments. Here, a method to integrate electrospun fibers with microfluidic networks was developed in order to form complex cell microenvironments with the capability to vary relevant parameters. Spatially defined regions of electrospun fibers of both aligned and random orientation were patterned on glass substrates that were irreversibly bonded to microfluidic networks produced in poly-dimethyl-siloxane. Concentration gradients obtained in the fiber containing channels were characterized experimentally and compared with values obtained by computational fluid dynamic simulations. Velocity and shear stress profiles, as well as vortex formation, were calculated to evaluate the influence of fiber pads on fluidic properties. The suitability of the system to support cell attachment and growth was demonstrated with a fibroblast cell line. The potential of the platform was further verified by a functional investigation of neural stem cell alignment in response to orientation of electrospun fibers versus a microfluidic generated chemoattractant gradient of stromal cell-derived factor 1 alpha. The described method is a competitive strategy to create complex microenvironments invitro that allow detailed studies on the interplay of topography, substrate surface properties, and soluble microenvironment on cellular fate processes.     

Will You Listen? An Examination of Parasocial Interaction and Credibility in Radio

A quasi-experiment was designed to examine the effects of social media on parasocial relationships and credibility for on-air radio hosts. Hypotheses and research questions were tested using 4 experimental conditions. A sample of 240 participants were randomly assigned to a condition and then asked to complete a survey. Results showed that social media appeared to have a negative effect on the strength of a parasocial relationship as well as on credibility.     

Hazard and Outrage: Developing a Psychometric Instrument in the Aftermath of Katrina

This article details the development of a psychometric instrument measuring the constructs of hazard and outrage in the aftermath of Hurricane Katrina. The study focused on the interplay of perceived hazard and outrage in relation to evacuation from the New Orleans area, with specific attention to demographic differences. Perceptions of hazard and outrage during Katrina served to illustrate the utility of the scale in examining these responses across different demographic groups. Possible ways that this information can be used to design messages that alert audiences to hazards, yet successfully address the need for outrage, emerged from the study.     

Effects of Traditional Versus Montessori Schooling on 4‐ to 15‐Year Old children's Performance Monitoring

Through performance monitoring individuals detect and learn from unexpected outcomes, indexed by post‐error slowing and post‐error improvement in accuracy. Although performance monitoring is essential for academic learning and improves across childhood, its susceptibility to educational influences has not been studied. Here we compared performance monitoring on a flanker task in 234 children aged 4 through 15, from traditional or Montessori classrooms. While traditional classrooms emphasize that students learn from teachers' feedback, Montessori classrooms encourage students to work independently with materials specially designed to support learners discovering errors for themselves. We found that Montessori students paused longer post‐error in early childhood and, by adolescence, were more likely to self‐correct. We also found that a developmental shift from longer to shorter pauses post‐error being associated with self‐correction happened younger in the Montessori group. Our findings provide preliminary evidence that educational experience influences performance monitoring, with implications for neural development, learning, and pedagogy.
