Cost‐Effectiveness of Early Childhood Interventions to Enhance Preschool: Evidence from a Randomized Experiment in Head Start Centers Enrolling Historically Underserved Populations

We evaluate the cost‐effectiveness of two early childhood interventions that use instructional coaching and parent coaching as levers for improvement. The study design allows us to compare the individual effects of each intervention as well as their combined effect on student outcomes. We find that teachers receiving instructional coaching improve their use of evidence‐based instructional practices, while families receiving parent coaching show increases in numerous responsive parenting behaviors associated with positive child outcomes. Both interventions demonstrate positive impacts on students, but only parent coaching shows statistically significant effects across a range of student outcomes. Instructional coaching alone is substantially less costly and may therefore be the most cost‐effective of the three treatment conditions; however, small sample sizes limit our ability to reach definitive conclusions. Policy simulations suggest that implementing these interventions could raise the overall cost‐effectiveness of Head Start by at least 16 percent.     

“Lucy says today she is a Labordoodle”: how the dogs-of-Instagram reveal voter preferences

Instagram is an image-centric social media application, launched in October 2010 with the explicit aim of allowing members to share their smart phone photos with the world. Posts typically combine photographs with a short verbal text, and as such provide fertile ground for multisemiotic analysis. Further, at times of political significance or upheaval, Instagram, like other social media platforms, provides a space for the public to express opinions or emotions. The fact that citizens do this through a combination of words and images on Instagram is the subject of analysis in this article. Using a dataset of 92 Instagram posts that made use of the discourse tagging hashtag #dogsatpollingstations at the time of the 2016 Australian federal election, this study demonstrates the multisemiotic strategies used by members of the public to show their dissatisfaction with the incumbent government, and their endorsement of other political parties. The study also demonstrates the triangulation of multiple methods, and as such is an example of corpus-assisted multimodal discourse analysis.     

Homeland and its use of bipolar disorder for sensationalist and dramatic effect

When a lead character in a critically acclaimed and award-winning television programme is depicted as a proficient and meticulous heroine with a mental disorder, it is crucial to examine if this reflects a change in the media depiction of people with mental illness. This article employs framing analysis to examine the portrayal of lead CIA agent with bipolar disorder, Carrie Mathison, in Homeland. Although the show did initially associate competence, intellect and astuteness to this character, as it progressed, the framing decisions used for dramatic and sensational purposes ultimately presented Mathison within the usual stereotypical depictions: as impulsive, irrational, unpredictable, unstable, dangerous and disordered. Given the popularity of the show, responsible depictions should take priority over dramatic effect at the expense of a character with mental illness because sufferers may be deterred in speaking about their illness and seeking appropriate treatment if such negative themes persist.     

Regulating Autonomy: An Assessment of Policy Language for Highly Automated Vehicles

Self‐driving cars (also known as driverless cars, autonomous vehicles, and highly automated vehicles [HAVs]) will change the regulatory, political, and ethical frameworks surrounding motor vehicles. At the highest levels of automation, HAVs are operated by independent machine agents, making decisions without the direct intervention of humans. The current transportation system assumes human intervention though, including legal and moral responsibilities of human operators. Has the development of these artificial intelligence (AI) and autonomous system (AS) technologies outpaced the ethical and political conversations? This paper examines discussions of HAVs, driver responsibility, and technology failure to highlight the differences between how the policy‐making institutions in the United States (Congress and the Public Administration) and technology and transportation experts are or are not speaking about responsibility in the context of autonomous systems technologies. We report findings from a big data analysis of corpus‐level documents to find that enthusiasm for HAVs has outpaced other discussions of the technology.     

Political Brand Communities as Social Network Clusters: Winning and Trailing Candidates in the GOP 2016 Primary Elections

This study integrates a brand community theoretical framework and a social networks approach to the study of political marketing on social media. It analyzes Twitter activity by and about all Republican candidates during the month of January 2016 prior to the Iowa primary caucus. Specifically, it identifies key patterns of information flow and political brand community emergence surrounding each candidate as well as brand social mediators who play influential roles in content flow. Findings detect network clusters - subgroups of siloed users - who converse to exchange information with one another rather than with disconnected others in any given political brand community. We classify these clusters in two groups: direct communities that surround a brand – here, a candidate – and indirect communities that consist of users who talk about the political brands but are not directly connected to the brand. Within this fragmented community structure, brand social mediators have the power to bridge direct and indirect brand communities across the network. Among the winning and trailing brand communities, different sets of brand social mediators, patterns of information flow, and network structures emerge. The findings suggest that the more successful a political brand is in voter polls, the weaker the social ties and relationships are within the brand communities. The interactions between political brands and their direct vs. indirect communities also exhibit different patterns of information flow. While direct brand communities demonstrate a higher level of reciprocity, indirect brand communities show a higher level of density. Implications and directions for future research are discussed.     

Designing for equitable civic engagement: Participatory design and discourse in contested spaces

A common theme of research on participatory democracy and citizen engagement centres on the need for empirical studies that conduct a deep exploration of the nuances and complexities of these processes. This article offers a distinct response to this need through an examination of two ethnographic case studies of a participatory budgeting process in a multilingual, highly diverse community in which Spanish-speaking Latino immigrants were involved. By analyzing participants discourse from the case studies, the findings highlight the risks and rewards of reframing participatory processes as design decisions rather than static procedures.

Simulation-based reconstruction of traffic incidents from moving vehicle mono-camera

Video recordings from digital cameras implemented in road vehicles present a valuable source of data concerning various dangerous traffic situations, i.e., road accidents or near-miss incidents. This data is readily available and numerous methods for forensic reconstruction of traffic situations from vehicle video were presented in the past. New alternative method for reconstruction of traffic situations from vehicle video is presented in this article. The method is based on the fusion of kinetic vehicle trajectory simulation within 3D laser scanner point cloud, projective geometry, and processing of video footage from moving vehicle camera. The method offers accurate reconstruction of general vehicle motion within relevant time domain whereby in-depth technical information about traffic incident can be quantitatively extracted from video footage. The result is physics-based 3D projection of simulated vehicle motion on the motion of real vehicle recorded by moving monocular camera. The method was validated within performed experimental test runs with respect to vehicle speed, distance travelled, acceleration/deceleration and directional quantities (yaw rate, yaw angle). The method was further applied in the reconstruction of real-world traffic events.
