Time‐Intensive Information Technology and Human Welfare in Developing Countries

Abstract

This paper is concerned with the scope for developing countries to benefit from the Internet in non‐synchronous ways that is, in cases where some delay is involved in the delivery of information, as compared with the real‐time alternative used in developed countries. The first part of the paper draws on insights from Becker and others, to argue that poor people in poor countries are wont to exchange (relatively abundant) time for reductions in the cost of Internet use. The second part of the paper then examines whether such time‐intensive products actually exist and to the extent they do, how the required degree of cost reductions are effected in practice. I conclude that time‐intensive Internet technology represents a highly promising opportunity for developing countries to close the digital divide, an opportunity that warrants serious academic scrutiny.     

锁相环型频率综合器中高速分频器的研究

对锁相环型频率综合器中的高速分频器进行了较为深入的分析。比较了同步分频器和异步分频器,表明了异步分频器在高频应用中的特点。对相位切换型异步分频器中第1级和第2级2分频电路的实现方案进行了仔细分析和对比,并针对Wang提出的2分频电路中存在的电荷分享问题提出了改进方案,仿真显示改进后的电路有效解决了电路中的电荷分享问题。采用Chartered 0.35μm 2P4M CMOS工艺,对第1级与改进后的第2级2分频电路整体仿真显示,电路的最高工作频率为3.3GHz,电流消耗为1.9mA。     

Assessing Research Compliance for Federally Funded Projects: The Good,the Bad,and the Publicly Accessible

Abstract

In 2016, Utah State University launched a program to ensure their campus’ federal grant recipients were in compliance with funder mandates to share any data or publications produced as a result of the award. This article discusses how a cross-institutional team of librarians and administrators evaluated the success of this program using online asynchronous focus groups (OAFG) in conjunction with a traditional survey. The challenges and successes of using OAFGs to assess library services are also examined. An OAFG gave participants greater convenience, flexibility, participation, and time to craft answers, eliminating some of the hurdles to traditional focus group participation.

Socio-emotional connections: identity,belonging and learning in online interactions. A literature review

This review focuses on three interconnected socio-emotional aspects of online learning: interaction, sense of community and identity formation. In the intangible social space of the virtual classroom, students come together to learn through dialogic, often asynchronous, exchanges. This creates distinctive learning environments where learning goals, interpersonal relationships and emotions are no less important because of their ‘virtualness’, and for which traditional face-to-face pedagogies are not neatly transferrable. The literature reveals consistent connections between interaction and sense of community. Yet identity, which plausibly and naturally emerges from any social interaction, is much less explored in online learning. While it is widely acknowledged that interaction increases the potential for knowledge-building, the literature indicates that this will be enhanced when opportunities encouraging students’ emergent identities are embedded into the curriculum. To encourage informed teaching strategies this review seeks to raise awareness and stimulate further exploration into a currently under-researched facet of online learning.     

How much has my co-worker contributed? The impact of anonymity and feedback on social loafing in asynchronous virtual collaboration

This paper reports an experiment that investigates how feedback about co-worker's performance and anonymity affect a team member's performance in an idea generation task conducted asynchronously. The results indicated that there was no main effect of anonymity: anonymity by itself did not affect group performance. Receiving information about co-worker's performance increased group performance; however, the perceived level of co-worker's performance did not affect group performance. Participants who perceived that their co-workers had high performance experienced significantly more social comparison with identified input than with anonymous input. However, this motivation gain did not translate into a performance gain. Implications of these results and future research are discussed.
