Using computerâbased tests for information science
Computerâbased tests have been used extensively in the Department of Information Science at the University of Portsmouth, both for endâofâcourse examinations and continuous assessment. This paper details the use of computerâbased objective testing as an innovative technique for traditional assessment, and the separate problems of continuous computerâaided assessment. Results from three years of research have led to plans for future developments within the department, and the paper provides a checklist of considerations regarded as crucial
Designing intelligent computerâbased simulations: A pragmatic approach
This paper examines the design of intelligent multimedia simulations. A case study is presented which uses an approach based in part on intelligent tutoring system design to integrate formative assessment into the learning of clinical decisionâmaking skills for nursing students. The approach advocated uses a modular design with an integrated intelligent agent within a multimedia simulation. The application was created using an objectâorientated programming language for the multimedia interface (Delphi) and a logicâbased interpreted language (Prolog) to create an expert assessment system. Domain knowledge is also encoded in a Windows help file reducing some of the complexity of the expert system. This approach offers a method for simplifying the production of an intelligent simulation system. The problems developing intelligent tutoring systems are examined and an argument is made for a practical approach to developing intelligent multimedia simulation systems
A course-oriented intelligent tutoring system with probability assessment
Most Intelligent Tutoring Systems (ITSs) in the past have concentrated on
small domains and have been topic-oriented. They have tended to be non-extendable
prototypes and have neglected the expertise of human teachers.
It is argued here that a promising approach at this time is to design
course-oriented ITS shells which are based on the human teacher. Courses
using such shells could be used to take some of the load of first-time
delivery and assessment from teachers and lecturers, and leave them more
time for individual tutoring. [Continues.
From Ideas to Practice, Pilots to Strategy: Practical Solutions and Actionable Insights on How to Do Impact Investing
This report is the second publication in the World Economic Forum's Mainstreaming Impact Investing Initiative. The report takes a deeper look at why and how asset owners began to include impact investing in their portfolios and continue to do so today, and how they overcame operational and cultural constraints affecting capital flow. Given that impact investing expertise is spread among dozens if not hundreds of practitioners and academics, the report is a curation of some -- but certainly not all -- of those leading voices. The 15 articles are meant to provide investors, intermediaries and policy-makers with actionable insights on how to incorporate impact investing into their work.The report's goals are to show how mainstream investors and intermediaries have overcome the challenges in the impact investment sector, and to democratize the insights and expertise for anyone and everyone interested in the field. Divided into four main sections, the report contains lessons learned from practitioner's experience, and showcases best practices, organizational structures and innovative instruments that asset owners, asset managers, financial institutions and impact investors have successfully implemented
Food Security and the International Wheat Agreements
The paper examines the issues involved in reaching a workable international agreement on reserve stocks for wheat. The paper is divided into two parts. In the first part, there is an examination of past efforts to achieve greater food security through international wheat agreements and food aid and an evaluation of the extent to which they succeeded until 1969, when the pricing provisions of the agreement broke down. There is a survey of the institutions that were created following the World Food Conference in 1974, an examination of the issues that have prevented the successful conclusion of a new agreement in the 1970's, and a review of the direction of current negotiations. In part 2, the issue of wheat price stability is examined against the background of the objectives of the major participants in the international market. It is argued that the determination of appropriate measures to ensure world food security has been hampered by domestic agricultural objectives of the major trading nations. Even if agreement on a reserve stock could be reached, it is probable that a reserve stock alone would be inadequate to achieve price stabilization without some change in the trade policies of the major trading nations. Since it is unlikely that these policies will e completely abandoned, it is argues that an international code of conduct to limit their harmful effect is appropriate. The outlines of such a code are suggested
