Visually Assessing the First Lady in a Digital Age: A Study of Michelle Obama as Portrayed by Journalists and the White House

In a digital age in which the First Lady’s image is captured and disseminated by many different outlets, this article proposes the development of a coding instrument using Goffman’s (1979) gender displays as a new method for exploring the visual frames of the First Lady. Given the manner in which photographs are disseminated via the Internet by both official and journalistic sources, this new coding instrument takes into consideration the different vantage points that these image capturers have. Until recently, visual gender display frames of the First Lady from differing outlets have not been easily studied separately, given the fact that images disseminated by the White House had to go through the journalistic gate prior to dispersion. Ultimately, the study of photos of the First Lady as she appears in the “media” was mixed and confounded journalistic and official framing. The Internet has changed all of this and opens opportunities to study these framing sources separately. As a test of a new coding instrument to study these different framing sources, this article assesses Michelle Obama in her gender portrayal from two different framing sources: journalists and the White House. This visual content analysis demonstrates and supports the use of a new context-independent coding instrument, borrowing from Goffman’s gender displays as a method for visually studying the First Lady.     

Coverage of Veterans of the Wars in Iraq and Afghanistan in the U.S. Media

To evaluate how the media frames veterans of the wars in Iraq and Afghanistan, this study systematically assesses the discourse on Iraq and Afghanistan veterans in the New York Times and Washington Post from 2003 to 2011. Our analysis of a stratified sample of 151 articles featuring veterans from either the wars in Iraq or Afghanistan finds that the media frames veterans as damaged by their service but deserving of government benefits and social assistance. When the media frames veterans as actively engaging in society, their social engagement is often because of or despite their injuries or mistreatment. We find interplay between victimization and deservingness such that depictions of the cohort as physically and mentally damaged complement and justify arguments for a sustained high level of benefits to accommodate the needs of veterans. We thus argue that generous benefits for veterans partly stem from their depiction as having suffered from their service.     

金额/比率陈述方式和调节匹配对消费者购买意愿的影响

研究引入调节匹配这个源于心理学的概念,探讨两种不同目标导向——求成与避败的消费者面对两种不同的信息陈述方式——金额与比率时对购买意愿的影响。结果表明：信息陈述方式与消费者目标导向产生匹配,才能对消费者态度及其购买意愿产生积极的正面影响;消费者动机存在干扰效果,尤其在消费者属于高动机的情况下,原本对促销信息陈述没有匹配的消费者转变为匹配,且消费者态度明显提升。     

Are children more paternalistic than their mothers when choosing snacks?

This paper focuses on an experiment in which mothers and their child separately chose between relatively healthy foods (flasks of stewed apples) and relatively unhealthy foods (candy bars). Each participant first filled up a first bag for her/himself, and then, a second one for the other person of the dyad. A simple nutritional message on vitamins and sugar contents of foods was then provided, and subsequently each participant filled up a third bag for her/himself and a fourth one for the other person of the dyad. The results show that before revealing the nutritional message, mothers are, on average, “indulgent”, which means that they choose a lower number of relatively healthy foods for their child than the one they choose for themselves. Children tend to be rather “paternalistic”, which means that they choose a higher number of relatively healthy foods for their mothers than they choose for themselves. The nutritional message leads many mothers and children to significantly increase the number of relatively healthy foods selected for themselves and for the other person. The mothers’ indulgence versus the children’s paternalism, along with the children’s reactivity to the message, suggest that mothers underestimate the children’s acceptance of healthy food.     

Participatory video analysis in disability research

This article sets out critical framing as an analytical approach in participatory video by which people investigate and analyze a topic through arts-based engagement, storyboarding, and collaborative editing. Participatory video as an action research method in self-advocacy has been discussed elsewhere. Here, the author examines critical framing and the role of generative themes in participatory analysis by describing a case study in which adults with developmental disabilities explored the dimensions of sexual health through participatory video. The author proposes that critical framing provides a more nuanced approach to participatory analysis. Credibility and trustworthiness with data triangulation and overall findings are also described.     

Worlds apart,worlds together: converging and diverging frames in climate and energy governance

This paper argues that past research has overlooked how the way problems and solutions are framed contribute to a prevailing gap in the global governance of climate and energy. Empirically, this paper investigates the frames of energy and climate change as expressed in key documents from the International Panel on Climate Change (IPCC) and International Energy Agency (IEA). Partly in contrast to past research, this paper finds (1) that there is a growing similarity in how the IPCC and IEA frame climate and energy; (2) that the IEA has gone from ignoring to acknowledging climate change and the transformation to a low-carbon energy system; and (3) that there is a prevailing difference in emphasis, whereas the IPCC only marginally discuss energy, while the IEA is still mainly talking about energy needs and fossil fuels even if climate change and renewables have entered their agenda.     

The online news cycle and the continuous alteration of crisis frames: A Swedish case study on how the immediacy of online news affected the framing of the swine flu epidemic

Abstract

This explorative case study investigates how the continuous publication cycle and the immediacy of online news affected the Swedish news media framing of the swine flu epidemic between April and May 2009. The findings suggest that media framing changes continuously, several times a day, effectively painting different frames of the crisis. Consequently, an organization involved in this crisis may face stakeholders that have encountered contrasting frames depending on when they accessed the latest news. Furthermore, the results show that the speed of modifications seems to be highest in the initial stages of reporting when the flu was perceived as more dangerous. Because the crisis frames change constantly, this provides both a challenging crisis communication environment and an opportunity to influence and shape the frames by organizations that are aware of them and act swiftly.     

The Role of Implied Motion in Engaging Audiences for Health Promotion: Encouraging Naps on a College Campus

Abstract

Objective: Lack of sleep among college students negatively impacts health and academic outcomes. Building on research that implied motion imagery increases brain activity, this project tested visual design strategies to increase viewers’ engagement with a health communication campaign promoting napping to improve sleep habits. Participants: Participants (N = 194) were recruited from a large southwestern university in October 2012. Methods: Utilizing an experimental design, participants were assigned to 1 of 3 conditions: an implied motion superhero spokes-character, a static superhero spokes-character, and a control group. Results: The use of implied motion did not achieve the hypothesized effect on message elaboration, but superheroes are a promising persuasive tool for health promotion campaigns for college audiences. Conclusions: Implications for sleep health promotion campaigns and the role of implied motion in message design strategies are discussed, as well as future directions for research on the depiction of implied motion as it relates to theoretical development.     

MML clustering of multi-state,Poisson, von Mises circular and Gaussian distributions

Minimum Message Length (MML) is an invariant Bayesian point estimation technique which is also statistically consistent and efficient. We provide a brief overview of MML inductive inference (Wallace C.S. and Boulton D.M. 1968. Computer Journal, 11: 185–194; Wallace C.S. and Freeman P.R. 1987. J. Royal Statistical Society (Series B), 49: 240–252; Wallace C.S. and Dowe D.L. (1999). Computer Journal), and how it has both an information-theoretic and a Bayesian interpretation. We then outline how MML is used for statistical parameter estimation, and how the MML mixture modelling program, Snob (Wallace C.S. and Boulton D.M. 1968. Computer Journal, 11: 185–194; Wallace C.S. 1986. In: Proceedings of the Nineteenth Australian Computer Science Conference (ACSC-9), Vol. 8, Monash University, Australia, pp. 357–366; Wallace C.S. and Dowe D.L. 1994b. In: Zhang C. et al. (Eds.), Proc. 7th Australian Joint Conf. on Artif. Intelligence. World Scientific, Singapore, pp. 37–44. See http://www.csse.monash.edu.au/-dld/Snob.html) uses the message lengths from various parameter estimates to enable it to combine parameter estimation with selection of the number of components and estimation of the relative abundances of the components. The message length is (to within a constant) the logarithm of the posterior probability (not a posterior density) of the theory. So, the MML theory can also be regarded as the theory with the highest posterior probability. Snob currently assumes that variables are uncorrelated within each component, and permits multi-variate data from Gaussian, discrete multi-category (or multi-state or multinomial), Poisson and von Mises circular distributions, as well as missing data. Additionally, Snob can do fully-parameterised mixture modelling, estimating the latent class assignments in addition to estimating the number of components, the relative abundances of the parameters and the component parameters. We also report on extensions of Snob for data which has sequential or spatial correlations between observations, or correlations between attributes.
