与地质灾害有关的政策——发达国家的经验教训

发达国家具有在政策和立法框架内对付灾害的长期经验,然而,评价发达国家经验教训的重要一点是,这些经验教训应在受灾地区或国家的文化、法律和政治框架内加以借鉴.     

Generational Differences in Attitudes and Socioeconomic Status among Hispanics in Houston

The complex variety of experiences that characterize the current wave of immigration have prompted revisions in the classic model of straight-line assimilation; the most important alternative theory is based on the concept of "segmented" assimilation. This paper assesses the validity of these two perspectives with data on three generations of Hispanic immigrants in Houston. Contrary to the standard assimilation model, third-generation Hispanics are not staying in school longer, nor are they earning higher wages than members of the second generation. But contrary to the segmented-assimilation model, third-generation Hispanics also give no evidence at all of having assimilated into an "adversarial" culture that rejects mainstream American values and is presumably responsible for restricting their upward mobility. The data reaffirm the pivotal role of education in determining occupational mobility, and they point to the importance of identifying the external societal factors that account for the stalled progress in educational achievement among third-generation Hispanic Americans.     

Gauging the public's preparedness for mobile public relations: The “Text for Haiti” campaign

The technology acceptance model was created to measure the public's attitudes toward and acceptance of new technologies. Text messaging has been used in the public relations domain for crisis communication alerts, but there have been few attempts to use it in other domains. Through an electronic survey of previous American Red Cross donors, donors to the “Text for Haiti” campaign had more favorable attitudes than those who did not donate via text messaging. However, the survey participants did not completely reflect the technology acceptance model. Although they perceived that text message campaigns were easy to participate in, the path analysis revealed that these thoughts resulted in less desirable attitudes toward participating in the campaigns.     

Beyond image repair: Suggestions for crisis communication theory development

This commentary explores whether and how crisis communication theory needs to be adapted to account for the rise of social media. Through a review of existing theory, we offer recommendations for future research in the evolving media landscape.     

What remains of Abu Ghraib?: digital photography and cultural memory

Ten years on, the photographs from the US-operated Iraqi prison Abu Ghraib have become synonymous with the war on terror for highlighting an unseemly combat culture. This article focuses on the ongoing functions of these viral photos as objects of cultural memory and also highlights their use as war trophies. Drawing on theories of digital photography, emotional and gestural communication, visual semiotics, and cultural memory, this article examines six of the circulated images. Focusing on the symbolic, the visual contents of the photos are contrasted with the rhetorical account from criminal investigator Brent Pack in the documentary Standard Operating Procedure. While Pack concludes that these images are in fact abusive, he nevertheless dismisses the relevancy of the emoting individuals within the photographs. The arguments here take a particular shape: the pictorial display of emotion is not only relevant, but is essential to the communication of group identity and the perpetuation of cultural memory, which is reinforced by the role that digital photographic technology plays in aiding the circulation of this cultural memory.     

Examining the impact of social media on mood and body dissatisfaction using ecological momentary assessment

Abstract

Objective: To assess the effects of social media consumption on body dissatisfaction and negative affect using ecological momentary assessment, a method of assessment over time in the participants’ naturalistic environment. Participants: Woman college students (N?=?30) from a large public university participated in the study in Fall 2015. Methods: Participants were contacted via their smartphones five times per day for five days and asked to complete a battery of measures which assessed social media use, body dissatisfaction, and negative affect. Results: Results demonstrated that the number of social media sites visited was a significant predictor of body dissatisfaction while time spent using social media was not. The number of sites visited and time spent on social media were both significant predictors of general negative affect, sadness, and guilt. Conclusions: Results demonstrate the negative impact that social media use can have on body dissatisfaction and negative affect.     

Social Self‐Control,Externalizing Behavior,and Peer Liking Among Children with ADHD‐CT: A Mediation Model

This study investigated the role of externalizing behavior as a mediator of the relation between social self‐control and peer liking among children with attention‐deficit/hyperactivity disorder‐combined type (ADHD‐CT). A model was proposed whereby externalizing behavior would fully statistically account for the direct relation of social self‐control to peer liking. One hundred seventy‐two children ages 7.0–9.9 years with ADHD‐CT were rated by their teachers regarding their social self‐control and by their parents and teachers regarding their rates of externalizing behavior. Same‐sex classmates provided ratings of overall liking. Structural equation modeling was used to assess the proposed model. Results supported the proposed model of externalizing behavior as fully statistically accounting for the relation of social self‐control to peer liking. This study demonstrated the crucial role that externalizing behaviors play in the social impairment commonly seen among children with ADHD‐CT.     

Multiple family groups: an engaging intervention for child welfare-involved families

Differences between child welfare- and non-child welfare-involved families regarding barriers to child mental health care, attendance, program satisfaction, and relationship with facilitators are examined for a multiple family group service delivery model aimed at reducing childhood disruptive behaviors. Although child welfare-involved caregivers reported more treatment barriers and less program satisfaction than non-child-welfare-involved families, no significant differences exist between groups on average total sessions attended and attendance rates over time.     

Keeping hospitals operating during disasters through crisis communication preparedness

The public has high expectations that hospitals will provide compassion, care, and extensive support for both injured and uninjured disaster survivors. In the face of disasters like pandemics or terrorist attacks, hospital communicators must be prepared to effectively communicate internally, externally, and across organizations. Furthermore, in crisis situations, hospitals must apply guiding principles of public relations including relationship management and rumor management. There remains a shortage of literature examining strategic risk and crisis communication in healthcare settings, including best practices. We conducted 27 interviews with U.S. hospital personnel charged with disaster management and/or crisis communication. Key findings reveal communication challenges not identified in prior research, such as policing the media and managing up, as well as reinforcing existing generic best practices, such as accepting uncertainty.
