Making IT work for municipalities: Building municipal wireless networks

The lack of widely available, affordable broadband Internet access has spurred a movement in which municipalities are rolling out wireless broadband networks. This movement has raised a number of questions including: Why are municipalities acting as the early adopters of wireless broadband technology? How does increased state regulation of municipal broadband networks affect this trend and how can cities respond? As cities use wireless broadband technology to enhance services to citizens, the growth of municipal wireless deployments has transitioned from linear to exponential. In response, many states have passed laws to regulate and restrict cities' ability to own, operate, deploy, or profit from either telecommunications or information services. Current and pending laws will be examined to understand how cities can deploy a wireless broadband network under these regulations. An analysis of municipal facilities and technology expertise illustrates the opportunity for public–private cooperation in wireless deployments. This paper will show that cooperation is beneficial in many cases. Finally, current business models will be examined for their ability to foster cooperation between the public and private sectors, bridge the digital divide, and create competition among private sector providers.     

Schooling and Learning in U.S.-Mexican Families: A Case Study of Households

Recent research indicates that learning and the academic performance of Mexican-American students are influenced by the interplay of economic, cultural, linguistic, and educational factors. In this work, a household analysis is used to illustrate how students' schooling and academic achievement are influenced by household members' activities at home, in the community, and in the schools. The study reports that a household analysis help us understand the relative weight of these factors in shaping students' school performance, and that it also accounts for differential academic achievement in any Mexican-American community. This household analysis indicates that level of family stability and the social and economic conditions of poor communities are the strongest factors affecting students' learning and academic achievement.     

“We do not know what is the real story anymore”: Curricular contextualization principles that support indigenous students in understanding natural selection

We propose a process of contextualization based on seven empirically derived contextualization principles, aiming to provide opportunities for Indigenous Mexican adolescents to learn science in a way that supports them in fulfilling their right to an education aligned with their own culture and values. The contextualization principles we empirically derived account for Nahua students' cultural cognition, socialization, and cultural narratives, thus supporting Indigenous students in navigating the differences between their culture and the culture and language of school while learning complex science concepts such as natural selection. The process of curricular contextualization we propose is empirically driven, taking culture and socialization into account by using multiples sources (cognitive tasks to explore teleology, ethnographic observation of students' community and classroom, and interviews with students and community members) and builds on the scholarship in Culturally Relevant Pedagogy and Indigenous Education. We used these principles to redesign a middle school biology unit on natural selection to make it more culturally relevant for Nahua students. The enactment of this unit resulted in students being engaged in science learning and achieving significant learning gains. The significance of this study lies in presenting evidence that learning science in culturally relevant ways supports the learning of challenging biology concepts. We provide evidence that Western science can be learned in ways that are more aligned with Indigenous students' Traditional Indigenous Knowledge, thus informing the implementation of educational policies aiming to improve the quality of secondary education for Indigenous adolescents. Our proposed contextualization principles can benefit students of all cultural identities who feel that their religion, language, or traditional knowledge are not aligned with school science, facilitating their access to culturally relevant science education.     

From Findings to Theories: Institutionalizing Social Informatics

We focus here on the history, status, and future of social informatics. In doing this we build on the visionary work of the late Rob Kling. Social informatics research contributes insights and perspectives to the study of computing in our society that other approaches do not. We make the case that social informatics is on its way to becoming a scholarly institution: accepted as one of the several approaches to study computing, and in particular, the approach best suited to engage on computerization. In making this case, we highlight the value of social informatics, summarize its principles and common findings, point to current work and issues, illustrate the three perspectives through which to pursue this scholarship, and identify several current activities remaining for social informatics to institutionalize.     

Always Articulating: Theorizing on Mobile and Wireless Technologies

Through this article we theorize on the nature and effects of articulation work relative to the take-up and use of information and communications technologies (ICT). Articulation work is “work that enables other work”: that which links people, processes, and technologies within organizations. Articulation work in organizations is both common and too often invisible from a managerial or budgetary perspective. Drawing on data from a study of the introduction and implementation of mobile computing technologies into criminal justice organizations, we highlight two findings: (1) There exist ongoing but unmet articulation needs present in any organization or work system. (2) Articulation is cumulative. We find, that as work becomes more complex (such as adding new work tasks and using new technologies), there is more articulation needed. These findings raise issues with assessing the costs of articulation on individuals, and making arrangements to accommodate explicit and implicit articulation in organizational work, particularly around the take-up and ongoing use of ICT-based systems.     

Can weekly discussions in a sensory science course influence student's perception and confidence in their professional success skills?

The Institute of Food Technologists’ (IFT) success skills highlight the importance of developing professional skills in the food science curriculum. On the other hand, many students in higher education report that the public school system feels disconnected and unrelated to their future. In this context, this study aimed to evaluate student's perceived importance of professional skills, as well as to enhance their awareness and confidence in them. Students in a sensory science class at the University of Illinois completed a questionnaire at the beginning, middle, and end of the semester to assess their opinion of and self‐assurance in professional skills, such as writing technical reports, providing leadership, making formal presentations, and applying critical thinking. During the semester, students received basic training and guidelines on each skill and were given assignments and activities to practice them as part of their coursework. Results showed increased knowledge about the existence of IFT core competencies, as well as an increased motivation to practice success skills regularly. They also showed an increased perceived importance of presentation skills, leadership, dealing with group conflict, researching scientific information, and library resources. Confidence in 80% of the skills increased significantly by the end of the semester, after students had been presented with opportunities to practice and discuss the skills in groups. Students were also able to relate their learning of specific success skills to different course assignments. This study concluded that a general exposure to the importance of practicing professional skills in a college setting enhanced student's experiences and awareness by connecting them to their future professional careers.     

Food Engineering Education in Mexico, Central America, and South America

ABSTRACT: The teaching of food engineering (FE) in Mexico and Central and South America began more than 50 years ago, initially with programs related to Chemical Engineering and Chemistry. The first programs clearly denominated as FE emerged during late 1960s and early 1970s; the support of the Organization of American States (OAS) and United Nations (UN) in some cases and the Science and Technology for Development Program (CYTED), launched in the early 1980s, stimulated and strengthened the development of FE. Relevant developments on FE in Latin-America can be traced down to topics such as: evaluation of physicochemical and transport properties, water activity, high and intermediate moisture foods, food drying, modeling and simulation of processes, hurdle technology, minimal processing, and emerging technologies. At present, FE Education in Latin-America interacts and coexists with the new paradigms related to the design of preservation processes and the development of Biotechnology.
