Mobile phone images and video in science teaching and learning

This article reports a study into how mobile phones could be used to enhance teaching and learning in secondary school science. It describes four lessons devised by groups of Sri Lankan teachers all of which centred on the use of the mobile phone cameras rather than their communication functions. A qualitative methodological approach was used to analyse data collected from the teachers' planning, observations of the lessons and subsequent interviews with selected pupils. The results show that using images and video captured on mobile phones supported the teachers not only in bringing the outside world into the classroom but also in delivering instructions, in assessing students' learning and in correcting students' misconceptions. In these instances, the way the images from the mobile phone cameras supported students' learning is explained using a variety of approaches to understand how images support learning.     

Maximizing Access to Resources: A Distance Learning Librarian Joins Forces with Colleagues at Supporting (Proximal) Libraries

ABSTRACT

Saint Leo University faculty provide instruction at SCE sites located on eight community college campuses and three military bases in the Florida region. This article will examine ways in which the Distance Learning/Reference (DL/Ref) librarian facilitates off-campus student access to both the university library's online and print resources and to library resources at nearby supporting, or “proximal,” libraries for students who are too far from the University Campus to use anything except the Ask-a-Librarian, 1–800 reference, and Interlibrary Loan services. These students must rely on proximal libraries, which include large public library systems, library consortia, community college libraries, and military base libraries, for access to print resources as well as Internet access to the university's online content. Providing library access services for such a large, disparate group requires the additional combined efforts of administrators, other faculty librarians, and supporting libraries.

UCF Library Express: Planning a Faculty Delivery Service

As it becomes increasingly difficult to demonstrate the worth of the library to the academic community, gate counts and usage statistics are no longer enough. Showing the impact the library has on the community requires planning new services with outcome measurement from the start. This article outlines a project plan for launching a faculty book delivery service at the University of Central Florida's John C. Hitt Library using Rhea Rubin's (2006) Outcome Measurement model. The article reviews the relevant literature, analyzes the current internal and external climate in which the service will be implemented, discusses the logistical aspects of the service such as cost, delivery method, and staffing, and concludes by determining the goals and outcomes of the service based on these factors. This article is the first in a series of three articles that together make up an entire project planning and management document, including planning, marketing, and assessing the service. The plan in its entirety provides an example of how to apply the Outcome Measurement model in an academic library setting.     

移动信息服务的内涵与模式

在对移动信息服务与固定信息服务进行比较的基础上,分析移动信息服务的内涵、特点、内外影响因素和服务模式。移动信息服务是面向移动用户通过移动/无线信息网络与手持移动信息终端向用户提供的信息服务。移动信息服务模式包括主体模式、技术模式、内容模式、服务策略、面向用户的服务模式、即时服务模式、基于位置的服务模式、个性化服务模式等。

个体在信息传递中的行为对组织效率的影响

一项交易活动，无论发生在市场还是组织内部，都要涉及到对信息的收集处理等，而这会产生交易成本。组织中的交易和市场中的交易有所不同，个体的行为会对组织的效率产生影响。遵循对行为人的三种假设：有限理性、机会主义和自身利益最大化，分析组织中个体行为对内部信息传递的影响。     

基于延迟制造的客户订单分离点定位

通过建立基于成本的定量模型,对生产过程前s-1道工序的成本进行分析,将客户订单中要求的交货期作为约束条件引入模型,依据其不同取值范围得出4种情形下的客户订单分离点（CODP）最佳定位,并在分析4种情形的基础上将CODP最优解用公式表示．同时,分析总成本函数分别为常量函数、单调递增、单调递减、凸函数、凹函数及波浪形函数时的CODP定位最优解,并以实例对模型进行实证分析．     

农药戊唑醇在Chiralcel OJ-H柱上的拆分

在Chiralcel OJ-H手性柱上用正相色谱条件直接拆分了三唑类手性农药戊唑醇,得到了满意的色谱分离结果。考察了流动相中极性改性剂-不同种类醇的结构对手性拆分的影响。结果表明被研究的手性农药戊唑醇在正丁醇作流动相极性改性剂时拆分效果较好。
