E‐commerce is diffusing into developing countries (DCs), and is assumed to help deliver the international development agenda. But how can the connection between e‐commerce and socio‐economic development be conceptualised? The aim of this paper is to analyse that connection by drawing from the development studies discipline to take a broader perspective on e‐commerce than that so far provided by firm‐level research.

The authors adopt a literature survey approach, drawing their conceptual foundations from development studies, and supplementing this from the e‐commerce literature.

The paper develops a new, integrated model that explains the way in which e‐commerce can contribute to socio‐economic development.

This new model can help provide a foundation for future research on e‐commerce in DCs; research on e‐commerce policy as well as impact assessment research.

The discussion and model provide development agencies, governments, consultants and business people working in DCs with a clearer sense of the contribution e‐commerce can make; assisting them in prioritization, planning, and evaluation of e‐commerce projects.

The paper provides the first integrated perspective on the broader contribution of e‐commerce to the growth and development of DCs.

Surveys of senior real estate executives have previously indicated that real estate represents approximately 25 per cent of corporate worth. These surveys, however, relied on self reported estimates of current real estate value. This study uses objective data to investigate the proportionate value that real estate represents on corporate balance sheets. The findings indicate that, when buildings are adjusted for inflation, real estate represents about 40 per cent of total corporate assets. Since corporate worth may also be measured in market value terms, several indexes were constructed to measure the proportion of firm market value represented by real estate assets. With buildings inflation adjusted, real estate represents about 80 per cent of firm market value. Although firm size does have an impact on all the ratios computed in this study, the impact is fairly modest in virtually all cases

ARTICLES have been written from time to time in our professional journals dealing with the question of local collections. These articles have, however, dealt with the formation of such collections, the principles of collecting, methods of storage, and the best means of classifying and cataloguing the same. But I do not remember any of the writers advocating the establishment of what may be termed county libraries, i.e., special libraries in each county for the accumulation of everything relating to the county. All works that do not deal in some way or another with the locality would be outside the scope of such libraries.

In a previous article we have called attention to the danger of eating tinned and bottled vegetables which have been coloured by the addition of salts of copper and we have urged upon the public that no such preparations should be purchased without an adequate guarantee that they are free from copper compounds. Copper poisoning, however, is not the only danger to which consumers of preserved foods are liable. Judging from the reports of cases of irritant poisoning which appear with somewhat alarming frequency in the daily press, and from the information which we have been at pains to obtain, there can be no question that the occurrence of a large number of these cases is to be attributed to the ingestion of tinned foods which has been improperly prepared or kept. It is not to be supposed that the numerous cases of illness which have been ascribed to the use of tinned foods were all cases of metallic poisoning brought about by the action of the contents of the tins upon the metal and solder of the latter. The evidence available does not show that a majority of the cases could be put down to this cause alone; but it must be admitted that the evidence is in most instances of an unsatisfactory and inconclusive character. It has become a somewhat too common custom to put forward the view that so‐called “ptomaine” poisoning is the cause of the mischief; and this upon very insufficient evidence. While there is no doubt that the presence in tinned goods of some poisonous products of decomposition or organic change very frequently gives rise to dangerous illness, so little is known of the chemical nature and of the physiological effects of “ptomaines” that to obtain conclusive evidence is in all cases most difficult, and in many, if not in most, quite impossible. A study of the subject leads to the conclusion that both ptomaine poisoning and metallic poisoning—also of an obscure kind—have, either separately or in conjunction, produced the effects from time to time reported. In view of the many outbreaks of illness, and especially, of course, of the deaths which have been attributed to the eating of bad tinned foods it is of the utmost importance that some more stringent control than that which can be said to exist at present should be exercised over the preparation and sale of tinned goods. In Holland some two or three years ago, in consequence partly of the fact that, after eating tinned food, about seventy soldiers were attacked by severe illness at the Dutch manœuvres, the attention of the Government was drawn to the matter by Drs. VAN HAMEL ROOS and HARMENS, who advocated the use of enamel for coating tins. It appears that an enamel of special manufacture is now extensively used in Holland by the manfacturers of the better qualities of tinned food, and that the use of such enamelled tins is insisted upon for naval and military stores. This is a course which might with great advantage be followed in this country. While absolute safety may not be attainable, adequate steps should be taken to prevent the use of damaged, inferior or improper materials, to enforce cleanliness, and to ensure the adoption of some better system of canning.

The use of robots to control for quality in manufacturing raises the issue of choice and its effect on the probability of accepting defective parts or rejecting good ones. The application of robots to the quality gauges is described and robot repeatability and errors in production processes are examined.

The purpose of this paper is to examine the effects of the use of the citation‐based journal impact factor for evaluative purposes upon the behaviour of authors and editors. It seeks to give a critical examination of a number of claims as regards the manipulability of this indicator on the basis of an empirical analysis of publication and referencing practices of authors and journal editors

The paper describes mechanisms that may affect the numerical values of journal impact factors. It also analyses general, “macro” patterns in large samples of journals in order to obtain indications of the extent to which such mechanisms are actually applied on a large scale. Finally it presents case studies of particular science journals in order to illustrate what their effects may be in individual cases.

The paper shows that the commonly used journal impact factor can to some extent be relatively easily manipulated. It discusses several types of strategic editorial behaviour, and presents cases in which journal impact factors were – intentionally or otherwise – affected by particular editorial strategies. These findings lead to the conclusion that one must be most careful in interpreting and using journal impact factors, and that authors, editors and policy makers must be aware of their potential manipulability. They also show that some mechanisms occur as of yet rather infrequently, while for others it is most difficult if not impossible to assess empirically how often they are actually applied. If their frequency of occurrence increases, one should come to the conclusion that the impact of impact factors is decreasing.

The paper systematically describes a number of claims about the manipulability of journal impact factors that are often based on “informal” or even anecdotal evidences and illustrates how these claims can be further examined in thorough empirical research of large data samples.

Clip‐on ammeters check pipe corrosion. Corrosion control technicians working for British Gas, North Thames region are using clip‐on ammeters to detect low currents in domestic supply pipes. Gas mains feeding these pipes are already cathodically protected as part of the North Thames anti‐corrosion policy. However, the detection of low DC current at the customer entry point is a critical part of monitoring the overall performance of the pipe protection system.

Protective coating can survive swaging loads. A recent application of Whitford Plastics' Xylan surface coating illustrates the benefits of pre‐coating complex metal components prior to assembly.
