Accessibility as Aesthetic in Broadcast Media: Critical Access Theory and Disability Justice as Project-Based Learning

The obligation to make broadcast media accessible is often taught as the last step in media production. This article describes a year-long project that paired disabled media-makers with students to create three films and a podcast rooted in critical access theory and disability justice, which necessitated creative, collaborative access planning at the onset of each production. This public pedagogy project promoted technical skills and attitudinal change by applying an intellectual partnership model that allowed students to develop resistance to dominant discourses about access that centered disability in new ways—as a desirable production feature rather than as simply an “add-on.”

STATE OF THE ART OF BENCHMARKING: A SYSTEMATIC LITERATURE REVIEW BEASED ON DEA APPROACH FROM 2003-2018

Benchmarking is an effective method for organizations to increase their productivity, quality of products, reliability of processes or services. The organization may make a comparison between its performance and that of the peers from benchmarking, and recognize their advantages as well as disadvantages. The main objective of the present systematic literature review has been the study of DEA benchmarking process. Therefore, it examined and gave a summary of various DEA models applied worldwide to improve benchmarking. Accordingly, a list of published academic papers that appeared in high-ranking journals between 2003 and February 2020 was collected for a systematic review of the DEA benchmarking application. Consequently, the papers selected have been classified according to year of publication, purpose of research, outcomes and results. This study has identified eight major applications including: transportation, service sector, product planning, maintenance, hotel industry, education, distribution and environmental factors. They take up a total of 82% of all application-embedded papers. Among all the applications, the highest recent development has been in both the transportation and service sectors. Results showed higher potential of DEA as a suitable evaluation method for the further benchmarking researches, wherein the production feature between outputs and inputs has been practically lacked or very hard to obtain.

Carbon Footprint of Milk from Pasture-Based Dairy Farms in Azores, Portugal

The dairy sector is a major contributor to greenhouse gas emissions. Pasture-based dairy production is sometimes credited as environmentally friendlier but is less studied than more intensive production systems. Here we characterize and calculate the carbon footprint (CF), using life cycle assessment, of the “Vacas Felizes” pasture-based milk production system, in the Azores archipelago. Impacts were determined for multiple functional units: mass, energy and nutritional content, farm, area and animal. We performed multivariate analysis to assess the contribution of production parameters to the CF. Finally, we performed a literature review to compare these results with other production systems. Results show that emissions from enteric fermentation, concentrated feed production and (organic and mineral) fertilizer application are the three main sources of impact. Milk yield is a key production feature for the determination of emissions. The average CF is 0.83 kg CO2/kg raw milk. At each milk yield level, the farms are approximately homogeneous. Compared with other studies, “Vacas Felizes” milk has a lower CF than 80 (out of 84) published CFs and on average it is approximately 32% lower.

Excitation Transfer via Instant Replay in the Microstructure of Broadcast Sport

Although a variety of tools are employed to package sport for at-home consumption, instant replay is among the most ubiquitous. Excitation transfer theory has been a useful lens for explaining how emotion compounds during sport consumption, but research has failed to explore how instant replay can serve to facilitate the transfer of arousal between sequential events in televised sport. This experiment invokes excitation transfer to examine how both the nature of content and instant replay can facilitate sustained arousal and enhanced evaluations of events in the context of college football. Results suggest the superiority of game content to facilitate excitation transfer, both in terms of objective measures of emotion and self-reported enjoyment. The production feature examined here, instant replay, yielded mixed results. Although it failed to consistently impact objective physiological measures of emotion, it did elicit enhanced enjoyment when the content being represented was intrinsically exciting.

Using CFD Technique to Investigate the Effect of Tire Roiling-Noise with Different Pattern Design

In general, when evaluating the effect of a sedan vehicle’s tire tread pattern design on the noise generated, the noise is measured by first carving the tires and then using expensive laboratory equipment to perform the measurements. The advantages of using this method are that the experimental results and the noise level produced from the tires (that go into mass production) feature minimal differences and that reliable tested data are produced. The disadvantages of this method are that molds must be created to produce slicks, and that substantial time is invested in the process of artificial carving and performing subsequent experiments, all of which increase the tire development time and cost. Therefore, the effect of a sedan vehicle’s tire tread pattern design on rolling noise was predicted in this study by employing the numerical calculation methods used in calculating fluid mechanics. The experimental results obtained by the Automotive Research & Testing Center (ARTC) were used to test the improved tread pattern designs to validate the reliability of the method proposed in this study and that the tire development time can be effectively shortened
