In recent years, the landscape for wireless technology has changed substantially, with profound implications for the evolution of last-mile access infrastructure. This paper provides a high-level introduction to emerging trends in wireless technology, with a special focus on how these are impacting municipal broadband deployments. Also discussed are some of the key architectural and design choices for wireless networking systems and their implications for cost and system performance. In addition, examples are provided regarding how the new wireless technologies are being deployed by municipalities in a variety of contexts, with reference to wireless technologies currently available from vendors. The policy implications of these trends are discussed further in a companion paper in this issue.  相似文献

Oh and LaRose (2016) contended that problem severity and channel publicness shape support seekers’ goals, time spent composing messages, and the sophistication of those messages. The current study seeks to replicate and extend Oh and LaRose’s study to produce a more accurate understanding of the factors that influence the sophistication of support-seeking messages online. Support seekers’ goals varied according to the severity of a stressor and the publicness of a channel, and the amount of time people spent composing a message influenced its sophistication. We extend the original study by examining associations that were not initially tested. Time spent composing messages mediated the influence of problem severity on the quality of people’s messages, and this effect was moderated by channel publicness.  相似文献

Counselors (N = 911) reported the research skills needed for practice and subsequent research training needs. Findings indicate that counselors have a high need for research skills at work, but training needs differ significantly by counselor type. Recommendations include increasing emphasis on single‐case design, survey design, and widely available data analysis tools.  相似文献

A visitor to a new country is assaulted by many changes, both environmental and cultural. Expecting things to be different the visitor is shocked by what he/she finds, thus the term culture shock. A second shock, possibly more traumatic, awaits the international sojourner upon his or her arrival home. The experiences of the returnee typically do not match his or her expectations. Frequently, the individual returning home is not anticipating adjustment difficulties. Compounding the problem is the fact that re-entry has not been widely recognized or researched and thus, little has been done to help individuals to prepare for it.Focusing on international students, who by definition return home, this paper refers to a wide range of social, cultural, political, educational and professional difficulties. The many variables which determine the extent of re-entry shock are identified and discussed. A group program is suggested as one strategy for assisting those about to return home. The results of a pilot study of such a program illustrate how it can be a powerful force to minimize the disorientation and shock of re-entry.This paper serves as a challenge to all those who are responsible or work with international students. Re-entry preparation is also a prerequisite if individuals, institutions, corporations, home countries and host countries are to maximize the benefits and minimize the problems of studying or working abroad.  相似文献

The dramatic growth in the number of children learning English as a second language in our country has led to a corresponding increase in the need to understand how teachers and schools can effectively teach children who are learning English as a second language. Many teachers report not feeling prepared to meet the needs of these children (National Center for Education Statistics, Teacher preparation and professional development: 2000. , 2002). The current study used focus group interviews to examine how Head Start teachers in one program addressed the special learning needs of children learning English in their classrooms. Key challenges involved communicating with children and their families in their home language. Teachers used other staff, parents, and children in the classroom to interpret. Strategies involved visual aids, pictures, gestures, and a welcoming classroom environment. Resources used by teachers were professional development and language skills of other staff. However, available resources were often underutilized and limited for teachers to use in meeting the challenges the teachers faced in the classroom. Suggestions are presented for overcoming the challenges and limited resources encountered by teachers, such as changes in preservice and inservice training opportunities, and second language learning opportunities for teachers. Further implications for training and research are discussed.  相似文献
