From protest to agenda building: Description bias in media coverage of protest events in Washington, D.C

Social movements often seek to draw attention to issues they deem important by organizing public demonstrations with the aim of attracting mass media coverage. But only a small proportion of all public demonstrations receives any media attention. This article asks whether even the minimal coverage that demonstrations receive reveal any influence of social movements in shaping how issues are framed by the mass media. Analyzing newspaper and television news stories on Washington, D.C. protests held during 1982 and 1991, we ask whether news reports on protests are framed in ways consistent with the aims of protesters. Do demonstrators receive media coverage that highlights the issues about which they are concerned, or does coverage focus on the protest event itself, to the exclusion of the social issues that movements target? Our results support much of the surmising among media scholars, that even when movements succeed at obtaining the attention of mass media outlets, media reports portray protests in ways that may undermine social movement agendas. Despite this obstacle to communicating protest messages through demonstrations, movements engage in other forms of communication that can affect public interpretations of mass media frames

Chemical and Organoleptic Characteristics of Pumpkin Flour Substituted Cookies

Cookies are a form of instant food preparation made from a mixture of the main ingredients of wheat with the addition of sugar, butter, and others. There is a need for local food ingredients that can replace some wheat flour to add the nutritional content of cookies, especially vitamin A, and reduce the use of wheat flour by substituting pumpkin flour in making cookies. This study aims to determine the best agent of pumpkin flour substitution on cookies' chemical and organoleptic characteristics. This study used a completely randomized design with a single factor: pumpkin flour substitution with 4 treatment levels 0%, 20%, 40%, and 60%. The results showed that cookies with 20% pumpkin flour substitution treatment were the best treatment based on chemical characteristics, including moisture content 6.34%, ash content 2.22%, fat content 22.52%, protein content 9.57%, carbohydrate content 59.32% and 0.79% crude fiber content, as well as organoleptic characteristics both hedonic and hedonic quality include color 3.0 (like) and 3.12 (yellow), taste 3.00 (like) and 2, 33 (slightly pumpkin flavoured), texture 3.00 (like) and 2.33 (a bit crunchy), and overall 3.00 (like)

Noyce Science, 2012-2021 Ten Cohorts of Teachers, Master of Arts for Science Teaching Brings Science to Life, UNL Noyce Track 1, Phase 2 Grant Activity Brochure

Summary of UNL NSF Robert Noyce Track 1, Phase 2 grant (2015-2020) to recruit and prepare new secondary science teachers and associated research activities. The perennial drive to recruit and prepare science professionals to become science teachers requires an enormous, collaborative effort. At the University of Nebraska–Lincoln, we have pledged ourselves to that worthy cause of educating new science teachers. This report summarizes the accomplishments of and celebrates those science teachers who have dedicated themselves to educating diverse youth and fostering a love of science in a world of STEM possibilities. They are the new generation of educators who face, and will continue to overcome, the challenges of education with perseverance and purpose. From 2011–2016, our first UNL National Science Foundation Robert Noyce Science Teacher grant supported 60 individuals in six cohorts who sought to become science teachers across Nebraska and many other states in high-need school districts. Many of these graduates also have graciously served as outstanding cooperating teachers to individuals in more recent cohorts. Our second Noyce grant made it possible to support 31 more pre-service science teachers with undergraduate degrees in an area of science across four cohorts. Like the six cohorts before them, they enrolled in the Department of Teaching, Learning, and Teacher Education’s Master of Arts with emphasis in science teaching (MAst) program. And like their predecessors, they are proving themselves dedicated professionals at a time when we need them in classrooms more than ever

Noyce Science Teacher Master of Arts with emphasis in Science Teaching Program: Meeting Challenges of 21st Century Classrooms. UNL Noyce Track I, Phase I, Final Report.

To meet the state’s and the nation’s need for more highly qualified science teachers, the 14-month Master of Arts with emphasis in science teaching (MAst) program was established in the College of Education’s Department of Teaching, Learning, and Teacher Education at the University of Nebraska-Lincoln, along with a Robert Noyce, Track I, Phase I grant from the National Science Foundation, awarded in 2010. This report presents a summary of the accomplishments of this Noyce grant, in which 60 post-baccalaureate science majors and professionals were provided with Noyce stipends to become science teachers. The MAst program is now in its sixth year, producing an average of 10 new science teachers per year. The project team, led by Dr. Elizabeth Lewis, was also awarded a second Noyce grant in 2015 to support 30 more individuals to become science teachers along with funding to continue to research the practices of beginning science teachers. The MAst program engages science professionals in a research-informed program of study that supports them in developing the knowledge, skills, and dispositions necessary to meet the challenges of the modern American secondary science classroom

Chokka squid on the Agulhas Bank: life history and ecology

Available knowledge is reviewed and new data incorporated in a synthesis of the life history and ecology of the chokka squid Loligo vulgaris reynaudii. We attempt to show that these aspects are essential to rational management of the resource. The life cycle is descriptionbed in detail from the egg to adult stage, mainly in biological terms, including a comprehensive descriptionption of maturation, migration and reproduction. Possible ecological interactions, particularly those of paralarvae and copepods, are discussed. Predator-prey relationships and the current state of knowledge on the effect of the physical environment on squid availability and abundance are summarized

Detectors for the James Webb Space Telescope Near-Infrared Spectrograph I: Readout Mode, Noise Model, and Calibration Considerations

We describe how the James Webb Space Telescope (JWST) Near-Infrared Spectrograph's (NIRSpec's) detectors will be read out, and present a model of how noise scales with the number of multiple non-destructive reads sampling-up-the-ramp. We believe that this noise model, which is validated using real and simulated test data, is applicable to most astronomical near-infrared instruments. We describe some non-ideal behaviors that have been observed in engineering grade NIRSpec detectors, and demonstrate that they are unlikely to affect NIRSpec sensitivity, operations, or calibration. These include a HAWAII-2RG reset anomaly and random telegraph noise (RTN). Using real test data, we show that the reset anomaly is: (1) very nearly noiseless and (2) can be easily calibrated out. Likewise, we show that large-amplitude RTN affects only a small and fixed population of pixels. It can therefore be tracked using standard pixel operability maps.Comment: 55 pages, 10 figure
