Item Front-page gatekeeping and content trends in 15 large-circulation newspapers(2006-12) Schroeder, Jared C.; Watts, Liz; Chambers, ToddThis study examines the state of gatekeeping and news judgment practices among major daily newspapers in three regions by studying their front-page content offerings. Using a content analysis of the story selections of 15 newspapers (five in each region), the results within each region were compared to those of the others using a set of 12 story topic categories. The newspapers were compared individually and as a group to the findings of a massive Readership Institute study that outlined what readers stated they want from their daily newspapers. The 15 newspapers were chosen because of their circulation, all 15 are among the 30 largest in the country in weekday circulation, and geographic location. The study sought a diverse group of papers in terms of media ownership and most of the nation’s top media markets are represented. Gatekeeping practices are similar, with differences appearing when regional or readership-specific needs arise to change the weights given to different stories. The results also show that in the current newspaper and overall media environment, newspapers that focus their resources on what their readership most values, wants and needs to know, and are easy to navigate will have a chance to compete or at least hold their readership in years to come.Item Handshake and Circulation Flow Control in Nanaphotonic Interconnects(2012-10-19) Jayabalan, JagadishNanophotonics has been proposed to design low latency and high bandwidth Network-On-Chip (NOC) for future Chip Multi-Processors (CMPs). Recent nanophotonic NOC designs adopt the token-based arbitration coupled with credit-based flow control, which leads to low bandwidth utilization. This thesis proposes two handshake schemes for nanophotonic interconnects in CMPs, Global Handshake (GHS) and Distributed Handshake (DHS), which get rid of the traditional credit-based flow control, reduce the average token waiting time, and finally improve the network throughput. Furthermore, we enhance the basic handshake schemes with setaside buffer and circulation techniques to overcome the Head-Of-Line (HOL) blocking. The evaluations show that the proposed handshake schemes improve network throughput by up to 11x under synthetic workloads. With the extracted trace traffic from real applications, the handshake schemes can reduce the communication delay by up to 55%. The basic handshake schemes add only 0.4% hardware overhead for optical components and negligible power consumption. In addition, the performance of the handshake schemes is independent of on-chip buffer space, which makes them feasible in a large scale nanophotonic interconnect design.Item Learning to write in (networked) public: children and the delivery of writing online(2014-12) Roach, Audra Katherine; Bomer, Randy; Hoffman, Jim; Maloch, Beth; Schallert, Diane; Hodgson, JustinThis investigation explored how three children (together with parents) developed networked publics that were diverse, well-connected, and powerful in the world. It was framed in response to calls in the field to better understand the new literacies young writers develop online and outside of school, and to increase literacy educators’ attention to the role of public audiences in writing and how writing is circulated. Performative case study methodology, ethnographic methods, and digital methods were employed to track and describe the online networks of three children (ages 11-13). These focal children were actively involved with their parents in social media, and had developed widespread networks with shared interests in children’s books and book reviews (Case 1), baseball (Case 2), and helping the homeless (Case 3). The children’s online networks were conceptualized as networked publics, drawing on Warner’s (2002) notion of publics as ongoing discursive relations among strangers, and on Actor-Network Theory’s notion of networks as assemblages of diverse interests that mobilize toward a common goal (Callon, 1986) and that develop stability in relation to ongoing circulations of texts (Latour, 1986; Spinuzzi, 2008). Research questions were framed broadly around the rhetorical canon of delivery [now digital delivery (Porter, 2009)], and were concerned with how writers distributed texts online, how those texts circulated, how the networked publics become more stable and powerful, and what instabilities children and parents had to negotiate in order to accomplish all of this. Data sources included interviews with 15 children and 28 adults, and fieldnotes observations of approximately 1,700 screen-captured webpages and other online artifacts. Findings showed that the young writers and their parents initiated and sustained networked publics through distribution practices that were oriented toward building trust; their texts displayed: interest, appreciation, reliability, service, credibility, and responsiveness. Both grassroots and commercial entities circulated texts in these networks, as they were sources of the ongoing renewal these different groups all needed in order to thrive. Sources of instability included conflicts over standards of writing quality, matters of profit, and the constancy of the demand to generate new interest and writing online. Children and their parents responded to these instabilities by welcoming and negotiating heterogeneous perspectives and partnerships. Implications of the study call for further research and teaching about the art of networked public discourse and digital delivery.
