A review of state‐of‐the‐art technology pertinent to tape automated bonding (for fine pitch, high I/O, high performance, high yield, high volume and high reliability) is presented. Emphasis is placed on a new understanding of the key elements (for example, tapes, bumps, inner lead bonding, testing and burn‐in on tape‐with‐chip, encapsulation, outer lead bonding, thermal management, reliability and rework) of this rapidly moving technology.

A review is given of the reliability of the ceramic chip carrier when solder‐attached to alumina thick film substrates. It is shown that no degradation occurs during humidity cycling or humidity steady state tests. Some diminution of the solder joint strength takes place during prolonged high temperature storage and temperature cycling but the effect is much more marked during power cycling. The effect of flux residues on thick film hybrids after solder reflow of surface mount components is assessed. No significant deterioration of any component, printed or discrete, that is attributable to flux is observed, given adequate cleaning techniques. The reliability of the ceramic leadless chip carrier is compared with both leaded ceramic and metal and plastic surface‐mountable components. The compliant leads of packages offer some advantages over the leadless chip carrier where thermal excursions are important but the leads themselves are easily damaged. Plastic packaging for surface‐mountable components continues to improve and become increasingly popular but potential reliability hazards associated with a thermal management performance inferior to that of ceramic and metal versions, moisture ingress and corrosion are seen to remain problem areas.

The purpose of this study is to examine individuals’ subjective perception of spare time available for activities that are more or less attractive.

Three experiments with adult samples manipulate liking of activity and temporal distance and assess the resulting predicted time available.

The authors demonstrate that individuals’ subjective perception of spare time is influenced by how much they like or dislike the activities they plan for. Individuals perceive they have more spare time for activities they like than ones they dislike. The strength of individuals’ liking for activities has more impact on perceived spare time available for liked activities than for disliked ones. These effects are attenuated by individuals’ propensity to plan.

Understanding the effect of spare time perception contributes to the literature on resource slack and provides insights into individuals’ planning for time.

We have on many occasions drawn attention to the all too prevalent fallacy of judging the nutritive and dietetic value of foods solely by their chemical composition without regard to the digestibility of the foods, and to the more or less prevalent idiosyncrasies of the public in connection with such foods. In an excellent article in The Times, Sir Wyndham Dunstan observes that “it has to be remembered that, however desirable the constituents of a given material may seem, in order to be of real value that material must be digestible— capable of assimilation within the body. In this matter of digestion people differ greatly and there must be latitude in the choice of food. While consumption in quantity of uncooked green and other vegetables is widely advocated, many are unable easily to digest some vegetables unless cooked, and not always then except in very moderate amount. Many other factors have to be taken into account in planning a common dietary. There are different tastes and preferences. The appeal a particular food makes to the individual and the appetite it stimulates are important points. The psychological factor plays a significant part and must be met by providing as wide a selection of palatable food as possible. These are a few truisms often overlooked.” With regard to the kind of bread we should eat and ought to be made to eat in war‐time, the writer observes that “there is unanimity in regarding a wholemeal bread (not always the same thing as “brown” bread) as that which should be generally eaten and readily procured. This is not at present the rule. Should it be made so? The constituents of wholemeal bread supply not only nourishment for the body but protection against ill‐health. Some of the more valuable constituents are absent from the white bread, so long the staple of this country, because they have been removed in the conversion of the wheat into white flour, which is now often further whitened and further deteriorated by a chemical bleaching agent. White bread is therefore a sophisticated and inferior food to which we have grown so accustomed that its use has become an ingrained habit. The obvious course in the circumstances, especially in war‐time, would be to compel the use of wholemeal bread and prohibit white bread. But, though such a course would be for the good of the nation, a sudden change of the kind, however beneficial, is bound to be inconvenient, if not distasteful, to many who are attached to white bread, and particularly to those who do not, or cannot, understand the need for change. There are people who say they can digest white bread more easily than “brown.” Thus it happens that the Ministry of Food, advised by numerous experts and confronted with numerous objectors, is apparently in favour of the evasive alternative of restoring artificially to white bread one at least of the valuable constituents it has lost in manufacture without impairing its whiteness. At first it was intended to do this by adding to white flour suitable quantities of two chemically prepared substances, one a vitamin and the other a calcium compound. Recently the synthetic vitamin only has been indicated as the proposed addition. This seems a clumsy and unnecessary concession to sentiment, involving considerable expenditure. It has been widely critised and regarded as “faking” bread. An eminent physician, Sir Ernest Graham Little, while condemning the proposal on general grounds, also questions its efficacy. Why first remove a natural constituent of wheat in making flour and then afterwards, at a cost, add to the flour this constituent artificially manufactured: He presents a convincing case for the use of wholemeal bread. With regard to the argument that some people dislike wholemeal bread and find it less easy to digest, it may be doubted whether many of them have eaten true wholemeal. “Brown” breads, including bread made with coarse ground wheat or bran and also several varieties of “brown” bread sold under largely advertised names, are almost everywhere procurable at higher prices than white bread. Fine wholemeal bread as well as flour is less easy to find. Large numbers of people eat very little bread, and it is therefore of small importance to them whether it is wholemeal or white. They consume far less than the three‐quarters of a pound a day included in Sir William Bragg's basal diet and make up for it with other foods which they can afford to buy. A really nutritious bread chiefly concerns the poorer classes, who eat much more bread than those better off. For the poor the substitution of wholemeal bread for white is a matter of far‐reaching importance. It has been stated that in many places wholemeal is dearer than white, but inquiries in the trade suggest that this is not as it should be, apart from “fancy” brown breads. As has been pointed out, the Ministry of Food, confronted with alternatives, apparently favour the introduction of “faked” white bread rather than the adoption of wholemeal. There is, however, a medium course. In this country we have come to recognise the “inevitability of gradualness,” and the medium course would meet present needs and might lead to the voluntary adoption of all that is desired.— It has been found that the admixture with fine ground wholemeal flour of about 10 per cent. of white flour makes a light coloured, very palatable, and digestible bread of good texture. Its nutritive value is very little less than that of full wholemeal bread; in fact a rather larger proportion of white flour would be permissible. The mixed flour is quite satisfactory for rolls, scones and cakes.” If an admixture of the kind suggested would overcome the prejudice against wholemeal bread and render it palatable to those people who dislike the ordinary wholemeal bread, there would seem to be a very strong case for adopting such a suggestion rather than first to remove a natural constituent of wheat and subsequently, at a cost, artificially add to the flour the constituent which has been removed in the manufacture of the flour.

In a global environment where terrorist organisations based in a poor country target a rich nation, this paper aims to study the properties of a dynamically incentive compatible contract designed by the target nation that involves joint counter-terror tasks with costly participation by each country. The counter-terror operations are however subject to ex post moral hazard, so that to incentivise counter-terror, the rich country supplies developmental aid. Development aid also helps avoid unrest arising from counter-terror activities in the target nation. However, aid itself can be diverted to non-developmental projects, generating a novel interlinked moral hazard problem spanning both tasks and rewards.

The authors use a dynamic model where the aid giving countries and aid receiving countries behave strategically. Then they solve for the sub game perfect Nash equilibrium of this game.

The authors characterise the optimal contract, showing that the dynamic structure of counter-terror resembles the shock-and-awe discussed by military strategists. The authors then prove that it is not necessarily the case that a more hawkish (resp. altruistic) donor is less pro-development (resp. softer on terror). In addition, the authors show that it may be easier to contract for higher counter-terror inputs when the recipient is more sympathetic to terrorists. The authors also discuss other problems faced by developing nations where this model can be readily adopted and the results can endorse appealing policy implications.

Sparked by the September 11 event, ethnic and religious diversity in the American culture has opened a new dialogue about tolerance to foreign cultures and religions. Using Burke’s views about morality and religious tolerance, this paper argues how ethical guidelines of public administrators ought to be sought from a universal moral law derived from natural principles and constitutional values of the regime. The argument focuses on Burkean prudence as a practical application of moral law and a guide for public administrators in a diverse global environment. Furthermore, it argues civil law to be inadequate in situations where the majority favors a particular opinion against a minority population. By acknowledging a universal moral law, public administrators can play a dual role as individuals building human relations in a diverse culture, and as public servants upholding Constitutional values to preserve the integrity of public institutions

The purpose of this paper is to develop rationalized Haar functions to approximate the solutions of the integro‐differential equations.

Properties of rationalized Haar functions are first presented, and the operational matrix of the product of two rationalized Haar functions vector is utilized to reduce the computation of integro‐differential equations to some algebraic equations.

Numerical results support the theoretical results.

Presents a method for solving integro‐differential equations.

Those of us who look back on a lifetime of work in librarianship, documentation and education—what is nowadays called communication—are often tempted to try to define our terms. Subconsciously we are probably trying to separate the sheep from the goats. Precision in terminology is necessary, especially in the sciences. But what I am going to talk about is more akin to the arts. I would like to take a more general, broader view of our function, our stake in the continuity and the quality of civilization as a whole.

The narratives that would give meaning to at least four generations of scholars and practitioners are amplified in the discourse growing out of the elements of technical rationality, pragmatism, evolution, and the rush of different ideas and new institutions that punctuate the Progressive period. The narratives explored below persist in public administration from the beginning of the twentieth century: preparation for the rise of national institutions, the citizen-state relationship, reconciling democracy and administration, and science and scientific management. Throughout the paper, the author's interest in the reconciliation of freedom and order is explored in the relationship between self and community, citizen and nation, and politics and administration.

One concern that has slowed the progress of surface mounted technology, in particular leadless chip carriers, has been the question of the reliability of the surface mount attachment technology. This concern follows from the realisation that the functional reliability of surface mount technology is a very complex issue involving many not very well understood components. What is needed is a relatively simple, useful, predictive model. The model reported here sidesteps the numerous complex underlying issues, which, if considered separately, make a predictive reliability model all but impossible, by taking a purely phenomenological approach and relegating second‐order effects to a lumped empirical figure of merit.
