The picture exchange communication system (PECS) is an established communication intervention for non-verbal children with autism. The purpose of this paper is to present an evaluation of a computer-based PECS approach, in which young non-verbal children with autism respond to an on-screen “virtual tutor” through the manipulation of picture/symbol cards. The paper presents research to investigate how the virtual tutor’s voice influences the children’s participation and performance.

Eight non-verbal children between six and nine years old and with a diagnosis of autism were presented with a series of computer-based activities, using a virtual tutor with either a natural or synthetic voice, in two separate sessions. Data were gathered using a within-participants counterbalanced design to control against variations between individuals and effects of presentation order.

Analysis of the children’s responses suggest that they were able to use the system more effectively when the virtual tutor had a synthetic voice, rather than a human voice. The findings demonstrate that a computer-based virtual tutor can provide an engaging method of supporting symbol-based communication for non-verbal children with autism, and that a synthetic voice type was preferable for the sessions undertaken.

Investigations of voice type and its influence on non-verbal children’s participation and performance have so far provided inconclusive results (Ramdoss, 2013). This research suggests that the voice type is an important feature of the learning experience of non-verbal children with autism, and can have a significant influence on their participation and performance in virtual tutor-led learning.

THE title of this short paper is somewhat of a misnomer, as the German Volks bibliothek is not the same as an English Public Library. As Dr. Schultze says: “When we speak of an English Public Library we know exactly what is meant, but the German Volks bibliothek does not convey any definite impression. Too often it still means a very small collection of books, probably gifts which are accessible to borrowers at certain hours each week. As a rule, the revenue is so trifling that after paying the small working costs there is little or nothing left for buying books.” Taking, therefore, the term Public Library for the sake of convenience, we may assume that the first Public Library in Germany was opened in Hamburg, in 1529, as the result of Luther's recommendation (1524) “that good libraries, especially in the large towns, should be established.” At the beginning of the 18th century, a number of free libraries were established, these were usually connected with churches and schools, yet their very name “free” seemed an invitation to everyone to share the treasures they contained. These libraries were principally in central Germany and Saxony.

It was stated by a philosopher of very early days that the Gods sell their choicest goods in the cheapest market; and, it may be added, if it is necessary to impress such an obvious truism, that the greatest poverty may often be found in the midst of riches. The herring well illustrates the truths of the above paragraph.

The purpose of this paper is to counter the misunderstanding by Paul Craig Roberts of empirical measures of economic freedom.

The objective is achieved by citing Roberts' criticisms of the Fraser and Cato studies of economic freedom and demonstrating the fallacies in his analysis.

The result of the present analysis is that Roberts misunderstands and misconstrues empirical measure of economic freedom. He conflates economic freedom with other desiderata, such as political freedom, personal liberties.

To the extent the widely publicized Roberts findings are believed by scholars, there will be less research conducted in this vitally important arena. To the extent that his errors are exposed, as, for example, by the present essay, there will be more research conducted in this vitally important arena.

The practical implication of this research initiative is to improve economic freedom around the world. If citizens are not even aware that there is such a thing as economic freedom, this will lessen the chances of it being implemented. Roberts' creation of red herrings and muddying of the waters around this topic, thus, unintentionally, diminishes economic freedom. One of the implications of the present article is to counter Roberts' influence in this matter.

What is new in the paper is that the fallacies in Roberts' critiques of empirical measures of economics are dissected.

The Government's Merchandise Marks Bill had an uneventful passage through the House of Lords and has been formally read a first time in the House of Commons. The main purpose of the Bill is to give greater protection to honest traders against less scrupulous competitors. With this object, the main provision of the Bill extends the definition of “trade description” so as to include statements as to “the quality, fitness for purpose, strength, accuracy, performance or behaviour of any goods.” In addition, the existing prohibition of false trade descriptions is extended to misleading descriptions, including any trade description which, although true in itself is calculated to be misunderstood or to create a false impression. It is hoped that the amendments will achieve also two other aims, namely, greater protection to the public generally and to the shopping public in particular, and better protection to the good name of British craftsmanship throughout the world.

For most people, especially those with fixed incomes, household budgets have to be balanced and sometimes the balance is precarious. With price rises of foods, there is a switch to a cheaper substitute within the group, or if it is a food for which there is no real substitute, reduced purchases follow. The annual and quarterly reviews of the National Food Survey over the years have shown this to be so; with carcase meat, where one meat is highly priced, housewives switch to a cheaper joint, and this is mainly the reason for the great increase in consumption of poultry; when recently the price of butter rose sharply, there was a switch to margarine. NFS statistics did not show any lessening of consumer preference for butter, but in most households, with budgets on a tight string, margarine had to be used for many purposes for which butter had previously been used. With those foods which have no substitute, and bread (also milk) is a classic example, to keep the sum spent on the food each week about the same, the amount purchased is correspondingly reduced. Again, NFS statistics show this to be the case, a practice which has been responsible for the small annual reductions in the amount of bread consumed per person per week over the last fifteen years or so; very small, a matter of an ounce or two, but adequate to maintain the balance of price/quantity since price rises have been relatively small, if fairly frequent. This artifice to absorb small price rises will not work, however, when price rises follow on one another rapidly and together are large. Bread is a case in point.

The purpose of this paper is to provide a selected bibliography of recent resources on library instruction and information literacy.

The paper introduces and annotates periodical articles, monographs, and audiovisual material examining library instruction and information literacy.

Information is provided about each source, and the paper discusses the characteristics of current scholarship, and describes sources that contain unique scholarly contributions and quality reproductions.

The information may be used by librarians and interested parties as a quick reference to literature on library instruction and information literacy.

This paper reports êndings of a study undertaken in late 1999 which aimed to identify and analyse the differences in use, by gender, of the Internet. A review of the literature of the differences in use, by gender, of computers generally is provided. The study involved students at Loughborough University and members of the public at libraries in Loughborough and Slough. The results of this (fairly limited) study show that female use, interest and conêdence in using the Internet is high but, in comparison with male respondents the females had not taken to the Internet as rapidly.

This article reviews the history of international coordination in the supervision of financial institutions noting why cooperation developed first and has been most extensive in oversight of banks relative to securities firms and insurance companies. It also poses the question of whether the extent of international coordination can be sustained or may even diminish.

The history of international coordination is used to illustrate the hypotheses that cooperation is more likely: the broader the international consensus on policy objectives and the potential gains from cooperation, the wider the international consensus on policy objectives and the potential gains from cooperation, the deeper the international agreement on the probable consequences of policy alternatives, the stronger the international institutional infrastructure for decision-making and the greater the domestic influence of experts who share a common understanding of a problem and its solutions.

All five of these factors that have enabled deepening and broadening of international cooperation have diminished in strength so that international cooperation is not likely to expand and may even be in retreat.

This article clarifies the factors that facilitate international cooperation and highlights the key obstacles to sustaining international cooperation.
