MORE than 200 delegates and observers from sixteen countries attended the International Federation of Airline Pilots' Associations (I.F.A.L.P.A.) Symposium on all weather landing, at the Hilton Hotel in Amsterdam from October 17 to 19, 1962. The Symposium, which was opened by Prince Bernhardt of the Netherlands, heard presentations from a considerable proportion of the equipment manufacturers in the automatic landing field, covering the current state of their system development and testing. More than half of the symposium was allotted to discussion and many of the pilots present expressed their opinions. The dominant theme of the discussion, naturally enough, was the proper place of the pilot in the all weather landing operation. This aspect of the operation is probably now the most contentious in the whole field and views expressed at this meeting might have been expected to be of great value to equipment and aircraft manufacturers. In fact, although much of interest was said, it cannot be recorded that there was a large measure of agreement between the pilots present.

Consumer loyalty has long been recognised as a key consideration of marketing strategies focused on customer retention. While the importance of the loyalty construct is widely recognised, the conditions and variables that foster consumer loyalty for a specific service may vary. This paper explores the variables that influence fan attendance at a professional sporting event. It extends prior research by conceptualising both a behavioural and an attitudinal component of loyalty, as well as considering fan involvement with the sport and attraction to the sport. The findings suggest that psychological commitment and resistance to change mediate the effect of fan attraction and involvement on behavioural loyalty in a professional sports context.

This paper discusses how learning-by-doing (LBD) criterion can be used to evaluate the sustainability of supply chains. This paper assesses the impacts of teamwork on the LBD criterion. Besides, the effect of the internship of new labors on the LBD criterion is discussed.

The repeat of a task leads to a gradual improvement in the efficiency of production systems. LBD occurs by accumulating knowledge and skills in multiple periods. LBD can be used to study changes in the efficiency. Efficiency can be improved by accumulating knowledge and skills. In this paper, the LBD criterion is projected on learning curve (LC) models. Furthermore, the LC models are fitted to the supply chains. Each supply chain may have a unique LC model. A minimum difference is set between the current performance of decision making unit (DMU) and the estimated performance of DMU based on DMU's LC. Hence, a point in which the LBD occurs is determined.

This paper develops an inverse network dynamic data envelopment analysis (DEA) model to assess the sustainability of supply chains DMUs. Findings imply that the LBD criterion plays an important role in assessing the sustainability of supply chains. Furthermore, managers should increase the internships and teamwork to get more benefit from the LBD criterion.

For the first time, this paper uses the LBD criterion to assess the sustainability of supply chains given the LC equations.

The services rendered by the Public Analysts of the country during the past seventy years in general and during the past five years in particular in the interests of public health is one of those imponderable national assets whose value to the community cannot be estimated in terms of the pound sterling or the pound avoirdupois. But there they are and the best acknowledgement is to say that a knowledge of what should be “the nature, substance, and quality” of our foods and drugs is largely based on the impartial and practical findings of the group of experts known generically as “Public Analyst.” All such reports, like this one for the year 1944, which is under consideration, strongly emphasise by their mere nature the increasing complexity and importance of the examination of foods and drugs under the main a,nd subsidiary acts and regulations. In fact the Public Analyst might, under present conditions, say, mutatis mutandis, with Bacon “so great is the accumulation of the statutes … and so intricate are they, that the certainty of the law is entirely lost in the heap.” We believe that when Bacon wrote there were about two thousand statutes on the books. By this time the number of regulations issued by the Ministry of Food in the interests of public health must have swelled almost to the dimensions of a legal code, but there the comparison ends. Many regulations have been issued as a result of conditions imposed by the War whereby the use of a corresponding number of what were well‐known constituents of foods has been either prohibited or limited in amount. The processing of foods has greatly developed. Many of these foods are produced under the stimulus of trade competition. The Labelling of Food (No. 2) Order, 1944, “by far the most important of the orders relating to the adulteration of food,” requires that the labels of pre‐packed foods must give the name or registered trade mark and address of the packer or labeller; and that the purchaser may have some idea of what he may be buying the quantity of each ingredient must be stated, or if this be not done then the ingredients must be listed in the order of their proportions beginning with the name of the one that occurs in the largest proprotion. The net weight of the food must be stated. Certain exemptions are allowed. Thus milk, fish, fruit, and vegetables preserved otherwise than by canning and bottling and for others whose composition is already controlled by regulation. The Order ensures that “the nature of new types of compound food … will be known at least in general terms.” The Report further says, “This Order is a great step forward in the history of food legislation, and will be welcomed by public analysts no less than by consumers, although it will certainly entail a very considerable addition to the analytical work already involved in the examination of foods, and will necessitate in the case of the determination of vitamins, the use of specialised technique and of expensive apparatus.” The Order states that if a food contains vitamins or minerals the minimum quantity of these per ounce must be specified on label or in advertisement. The same remarks will, we imagine, apply to the drawing up of food standards. The Ministry of Food is empowered to do this. Food standards have been urgently needed for a long time past and many are now in existence. These are official and binding as will be others as they appear. It will be noticed that they relate for the most part to more or less highly processed foods such as self‐raising flour, fruit curd, jam, marmalade, mincemeat, and coffee essence. The absence of official standards has tended to confusion and uncertainty. It may become a case of “so many men so many minds,” unless the offence be very gross and obvious. The “protective” foods, fresh milk, eggs, fruit, and vegetables are the most needful especially for the younger members of the community. Unfortunately they are the most costly and unless they be fresh are worse than useless. Milk qualitatively and quantitatively stands first on the list. The report states that the percentage of adulteration, 9·5, is the highest recorded for the years 1939 to 1944 inclusive. It is pointed out that it must not be assumed from these figures that 9·5 per cent. of the milk supplied to Birmingham is adulterated as 72 out of the 267 reported against were taken from only 12 vendors whose milk was suspected. The composition of the milk sold in Birmingham compares favourably as regards composition with those of five other towns or counties whose figures are quoted. Incidentally, it may be remarked that the legal limit of 8·5 per cent. of solids‐not‐fat and 3 per cent. of fat is a generous minimum, for from the figures given for the average composition of all samples of milk for 1944 it seems that the non‐fatty solids amount to 8·77 per cent. and fat to 3·65 per cent., while the average composition of all farmers' milks is practically the same. It is unnecessary to elaborate the point further beyond remarking that the figures given show that generally there is no excuse for poor quality milk. Unsafe milk, that is milk containing pathogenic organisms, is another matter. Particulars of prosecutions of five farmers for selling adulterated milk are given. In two of the cases mentioned adulteration, in one case certainly in the other case probably, was due to dishonesty of employees. In another case it seems that 57 gallons of “milk” represented by six samples contained 5½ gallons of added water! The milk coolers were found to be in order. The persistent and inexplicable leakiness of that piece of mechanism is frequently put forward as an excuse for the presence of extraneous water in milk. The cows, too, were young and in good condition. Presumably they were yielding milk of normal quality. It will also be remembered that the alleged all too ready response of these animals to slight variations in food or weather is sometimes given as a reason for fat deficiency. With regard to other foods reported against. The low available carbon dioxide content of baking powder, self‐raising flour and the like would seem to be due to old stock. The vendor in one case, “discovered at the back of the shop,” nine packets of old stock. Poor storage conditions; or unsatisfactory containers would also seem to be contributory. Other foods, some being of like character to the above named, have attained notoriety by being enriched with eggs, larvae, and mites. Other offences are of well‐known type. We have “coffee” with 15 per cent. of chicory in one case and about 33 per cent. in another. Orange flavour beverage powder containing, “among other things,” 13·4 per cent. of Epsom salts! Why? The packers would seem to have a penchant for Epsom salts. They had added this purgative before and were now asked to label the package giving the amount of Epsom salts. The only explanation that occurs to the writer is that it was the wish of the packers to rid the system as quickly as possible of the beverage before the “other things” had time to take an effective hand in the game. Two samples of rice contained an excess of French chalk. This had been used as a polishing agent in an attempt to attract the palate by pleasing the eye. Unfortunately this removes the germ plus vitamin B. This process was practised long before the existence of vitamin B was even suspected and the public has by this time so successfully humbugged itself into the belief that rice not so treated is unfit to eat that it would require another Order of the Ministry to protect the purchaser against himself. “Brawn” had a “most unappetising appearance.” It had been dyed a brilliant red and its make up—only 4 per cent. of flesh meat—was such “that by no stretch of the imagination” could it be called brawn. Yet even the sale of this stuff seems to have been successful. The brilliant red colour possibly doing the trick this time. “Honey.” In this case the word Honey was printed in large type and underneath “emulsified flavour” in small type. It consisted of a 2 per cent. solution of gum artificially flavoured of the consistency and appearance of honey. “The whole ‘get up’ was calculated to mislead as to the nature, substance and quality.” Tinned soup was described on the label as “extra concentrated,” and was alleged to make “twice the quantity of soup.” It was “no more concentrated than any other canned soup on the market.” “A packet of so called ‘stuffing’ was found to consist almost entirely of bread crumbs.” It was described as “very old stock.” The Ministry of Food insist on 7¾ per cent. of herbs being included. How “very old stock” could be even an explanation let alone an excuse we fail to see. In another case that ever useful word “improved” was used. “Improved Parrishes Chemical Food” was found not to correspond with British Pharmacopoeia requirements, and further the “word ‘improved’ hardly seemed applicable to a product containing 30 per cent. less of one of the principal constituents than the official article.” Then we come to “Port Wine.” As the result of a complaint—regarding the quality of rum and port, wine sold at a licensed house—samples were taken. The rum was found to be genuine. The port, however, consisted of “so called ‘British Wine.’” It seems that the licensee “had developed the very unfortunate habit of supplying it when asked for port.” The licensee was warned that he must disclose the nature of the drink when selling it. In 1944 5,302 samples were taken in Birmingham under the Food and Drugs Act. 368 of these or 6–8 per cent. were reported against. Those mentioned above are a few typical instances. Unfortunately no comparison with the rest of England and Wales in this respect is possible, the Ministry of Health having suspended the publication of figures. It is, however, certain that every such report introduces a new act in this comedy of errors with the Public Analyst as chorus.

By the beginning of the war, Germany's over‐all self‐sufficiency in food had reached a level of approximately 83 per cent., on the peace‐time basis of 2,200—2,400 calories per person per day. In respect to some types of food, however, the situation was not satisfactory. For example, before the war she produced approximately 73 per cent. of fish requirements, 12 per cent. of corn, 50 per cent. of legumes, and 60 per cent. of fat within her own boundaries. The country could be fed at a reduced level by the produce raised within its own boundaries if food were perfectly controlled and evenly distributed. However, in practice, individual provinces were much less favourably situated in this respect. Western Germany, an area of relatively small and diversified farms, was critically dependent on the eastern provinces for its flour, grain, and potato supplies. It is clear that all German civilians could be fed at a uniform level of adequacy during a war only by control of the country's food supply at the national level and by the continued operation of the new transportation network of the country. For this reason the bombing of rail and inland water transportation facilities became such a serious threat to national uniformity in food distribution. Of the many kinds of centralised food processing industries known in the United States, only a few played an important role in the food supply of German civilians. The principal examples of these were grain milling, sugar production and refining, and the large bakeries of urban areas. The damage or destruction of these facilities, incidental to air attack on other industrial targets, seriously decreased their production capacity. Bombing destroyed the mills for processing 9 per cent. of the German rye output and 35 per cent. of the wheat output. Of the sugar refineries four plants producing 300,000 tons annually, were destroyed. This represents a 38 per cent. decrease in production of sugar. Similarly bombing of chemical plants was largely responsible for the decrease in the supply for fertiliser nitrogen. In 1939, 718,000 tons of fertiliser nitrogen were available, but by 1945 this had decreased to 140,000 tons. The significance of this destruction of facilities vital to the feeding of a country already on a border‐line diet is ominous. Reliable estimates indicate that aerial bombings destroyed 35 per cent. of Germany's total (approximately 460,000 square metres) cold storage capacity. The increased use of cold storage intensified their dependence on transportation and on the continuity of the power supply. Aerial attack, as a result, not only decreased usable cold storage space, but also seriously interfered with the operation of the remaining space by impeding shipments and interrupting sources of power. It was the constantly reiterated opinion of all food officials that the bomb destruction of the transportation network was the largest single factor contributing to the disruption of the food supply. Bulk shipments which had been carried on inland waterways were seriously impeded by the bombing of canals. Aerial attack against railway lines, bridges and terminal facilities caused widespread interruptions in service and destroyed rolling stock, freight en route and handling facilities at terminals. It is not possible at this time to state exactly in what measure the curtailment of the national diet contributed to the ultimate defeat of Germany. The evidence available indicates, however, that it was an important factor. There is in any case no doubt that strategic bombing is the major element contributing to the present shortage of food in Germany. It was not apparent that the Germans considered the vitamin and mineral content of food in determining the ration allowances of the people. Immediately with the beginning of the war, all the principal foods were rationed, so that the lack of recognition of the importance of the vitamin and mineral content of this ration actually was an additional point of vulnerability for the German diet. With a food economy so vulnerable it is not surprising to have found that the basic food rationing programme was abandoned early in 1945 when the destruction of transport and communications by the strategic air offensive attained major proportions. This necessitated falling back on the inadequate system of regional self‐supply. The destruction of large food stocks, processing plants and cold storage plants by bombing also contributed to the general deterioration of the German food supply. There is ample evidence for the conclusion that as a result of the strategic air offensive the nutritional demands for the continued health of the German people could not be met.

“The organisation of any library depends on the men and women who work there. They have a very important job. They are the indispensable middle‐men of culture and science, and in opening this library we ought to remember that its success will depend on them as much as on what is in it.”—The Duke of Edinburgh, opening the Scottish Central Library on November 5th, 1953.

This paper examines the principal factors affecting the growth of intra‐group trade for four Latin American and Caribbean economic groups. Its findings suggest that the share of a group member's leading export sold within the group is an important determinant of intra‐group trade. For member countries that depend heavily on extra‐group markets, intra‐group trade is indirectly affected by the impact of extra‐group trade on gross domestic product.

Driving cycle is an essential requirement to evaluate the exhaust emissions of various types of vehicles on the chassis dynamometer test. This study presents a real world comparison of the driving cycles of Edinburgh motorcycles in two world cities; Edinburgh in Scotland and Delhi in India. The two driving cycles (EMDC & DMDC) driving cycle (EMDC) that were was developed through the analysis of experimental data. This data was collected from trips on a number of routes in each city. In Edinburgh, five different routes between the home addresses in the surrounding areas and place of work at Edinburgh Napier University in Edinburgh were selected. In Delhi data were collected in East Delhi (Geeta Calony) to Central Delhi (Raisena Road). The data collected data was divided into two categories of urban and rural roads in the case of Edinburgh while it was only the urban route in Delhi.. Forty four trips were made on the five designated routes in both urban and rural areas and 12 trips were made in Delhi. The aims of the study were to assess the various parameters (i.e. motorcycle speed, cruise, accelerations and decelerations and percentage time spent in idling) and their statistical validity over total trip lengths for producing a real world EMDC in each of the two cities. The results show that EMDC in Edinburgh, the EMDC has a cycle length of 770 and 656 seconds for urban and rural trips, respectively, which was found more than ECE cycle length. Time spent in acceleration and deceleration modes were found to be significantly higher than any other driving cycle reported to date for motorcycles, reflecting a typical characteristic of the driving cycle in Edinburgh; this was presumably due to diverse driving conditions of motorcycles in the city. In Delhi on the other hand, the DMDC has a cycle length of 847.5 seconds for the urban trips, which higher than that of the EMDC length. The overall percentage time spent in acceleration in Delhi was higher than that of Edinburgh while the time spent in deceleration was lower in Delhi. The overall average speed in the case of Delhi was slightly higher than that of Edinburgh.
