Hardgrove grindability index (HGI) is an important physical parameter used to demonstrate the relative hardness of coal particles. Modeling of HGI based on coal conventional properties is a quite complicated procedure. The paper aims to develop a new accurate model for prediction of HGI that is called optimized evolutionary neural network (OPENN).

The procedure for generation of the proposed OPENN predictive model was performed in two stages. In the first stage, as the high dimensionality involved in the input space, a correlation-based feature selection (CFS) algorithm was used to select the most important influencing variables for HGI prediction. In the second stage, a combination of differential evolution (DE) and biography-based optimization (BBO) algorithms as a global search method were applied to evolve weights of a multi-layer perception neural network.

The proposed OPENN was examined and compared with other typical models using a wide range of Kentucky coal samples. The testing results showed that the accuracy of the proposed OPENN model is significantly better than the other typical models and can be considered as a promising alternative for HGI prediction.

As HGI test is relatively expensive procedure, there is an economical interest on HGI modeling based on coal conventional properties (proximate, ultimate and petrography); the proposed OPENN model to estimate HGI would be a valuable and practical tool for coal industry.

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 coal-bearing strata of Longdong mine field in Xingtai is the Carboniferous-Permian. The No.8 coal seam is located in the Taiyuan formation and is the main minable coal-bed. The coal is mainly gas-fat coal accompanied with coking coal, lean coal and anthracite. The results of the macroanalysis and maceral quantitative analysis on the main minable coal-bed show that the degree of coal metamorphism takes the old town as the center and is distributed concentrically outward and the anthracite and lean coal are distributed nearby the old town, and the coal gradually becomes coking coal, gas-fat coal and gas coal further outwards. The degree of coal metamorphism was affected by regional metamorphism, and the coal seams which are close to the old town stack the regional magmatic thermal metamorphism. The conclusions of the research offer a scientific foundation to exploit the coal resource in this area?

Recently, American social behavior during the 1980s has been compared, both favorably and unfavorably, with the attitudes and culture of the United States during the years 1950–1959. The past two decades of rebellion, student protest, liberal sexual practices, radical politics, and strong civil and women's rights movements have all passed.

A series of online searches of the Harvard University Library System – which includes the Baker Library, Houghton Library and the Radcliffe Institute’s Arthur and Elizabeth Schlesinger Library – on the History of Women in America revealed nearly 1,000 archive and manuscript holdings on advertising and related topics. This paper aims to investigate the extent of these holdings, to assess their value to advertising and marketing historians and to explore their potential for encouraging future research on under-investigated topics and questions.

Described are the extensive and valuable special collections and other holdings related to advertising, business and marketing of the Harvard Library System. Also described are the availability of the holdings and recommendations for accessing and studying the collections and artifacts.

The research reported here supports an overall conclusion that the Harvard Library System holds an important place among the world’s repositories of valuable historical advertisements and marketing ephemera. The research also supports four specific conclusions regarding the historical value of Harvard’s collections and archives. First, some of the collections offer access to artifacts and items from an under-investigated period – the first half of the 19th century. Second, many of the collections are international in scope. Third, the collections represent a wide array of 19th century non-periodical advertisements and ephemera, such as trade cards, posters and theatrical playbills. Fourth, and most important, the collections offer significant potential for addressing, among other under-investigated topics, the important role of women in the development of modern advertising theory and professional practices.

A prior search for the world’s largest and most historically significant archives and collections of advertisements and marketing ephemera (promotional objects or media executions created for a one-time, limited purpose) revealed a handful of library and museum collections of exceptional size or topical importance meriting further investigation. This paper adds to an extensive line of research published in the marketing and advertising historical literature exploring and describing the breadth, depth and historical value of the world’s important collections of historical advertisements and ephemera.

THE Report of the Committee on Libraries, which was issued by the University Grants Committee in the summer of 1967, had for long been called the Parry Report after its Chairman, Dr. Thomas Parry, formerly Librarian of the National Library of Wales and at the time the Principal of University College of Wales in Aberystwyth. When it was first set up in June 1963 the terms of reference were as follows:

The purpose of this paper is to review Advertising in a Free Society – a defence of the advertising industry – by Ralph Harris and Arthur Seldon, and to evaluate its status as a justifiable forgotten classic of the marketing literature.

Advertising in a Free Society is placed in historical context (the Cold War), summarised and reviewed.

During the 1950s, as the UK experienced a period of affluence and growing consumerism, the advertising industry was again subject to the criticisms that had been levelled at it by influential scholars in the late nineteenth and early twentieth centuries. Against this context, Advertising in a Free Society deserves to be remembered as one of the earliest defences of advertising and remains highly relevant. Harris and Seldon were leading figures in the Institute of Economic Affairs (IEA), joining shortly after its inception, which became an influential group both in the UK and abroad, influencing policy on free markets.

Although Advertising in a Free Society attracted few citations (going out of print between its publication in 1959 and 2014 when it was republished by the IEA), and largely forgotten by marketing scholars, it provides a significant source for marketing historians interested in advertising criticism, the growth of the British advertising industry and the role of advertising in democratic societies. A reanalysis of the text situated in its historical context – the height of the Cold War – reveals that the text can be viewed as an artefact of the conflict, deploying the rhetoric of the period in defending the advertising industry and highlighting the positive role that advertising could make in free societies.
