To‐date, several segregated finite element algorithms have been proposed that solve the Navier—Stokes equations. These have considered only steady‐state cases. This paper describes the addition of the time‐dependent terms to one such segregated solution scheme. Several laminar flow examples have been computed and comparisons made to predictions obtained with both finite difference and finite volume solution schemes. The finite element results compare very well with the results from the other schemes, both in terms of accuracy and the qualitative behaviour of the iterative schemes.

We can by no means join in the pæan of self‐satisfaction which is sounded in the Library Association Record for January. There it is urged that three important months have passed since the Conference, and that they have been fruitful in energetic work and that the harvest is visible in the Council notes published in the same number. We have read them with sympathetic and critical care, but while we see evidence that some of the points raised at the Library Association Conference in October have been considered, we see very few results have been achieved. Questions we would ask are these:—

EVERY now and again, one of the solemn monthly or quarterly magazines, by way of enlivening its pages, inserts a terrific onslaught on municipal libraries, in which the judgment of heaven is called down upon the fiction reader, and the library authorities are condemned as a set of ignorant and inefficient office‐holders, who pander to a depraved public taste. The last assailant of this sort whom we had the pleasure of setting right was Mr. J. Churton Collins, who used the Nineteenth Century and After, as the medium for conveying his accusations. Now comes Mr. W. H. Harwood, who fills six‐and‐a‐half pages of the Westminster Review for February, 1906, with a quantum of twaddle about libraries, which differs from most recent articles of the same sort only in its dulness. In his use of this journalistic cliché, Mr. Harwood displays the customary ignorance of the Public Libraries Acts, by styling his paper “Free Libraries and Fiction,” and by his failure to prove even one of his statements by reference to a single concrete fact. Briefly, Mr. Harwood's position is this:—

During the industrial design process, a product is usually modified and analyzed repeatedly until reaching the final design. Modifying the model and regenerating a mesh for every update during this process is very time consuming. To improve efficiency, it is necessary to circumvent the computer-aided design modeling stage when possible and directly modify the meshes to save valuable time. The purpose of this paper is to develop a method for mesh modifications.

In contrast to existing studies, which focus on one or a class of modifications, this paper comprehensively studies mesh union, mesh gluing, mesh cutting and mesh partitioning. To improve the efficiency of the method, the paper presents a fast and effective surface mesh remeshing algorithm based on a ball-packing method and controls the remeshing regions with a size field.

Examples and results show that the proposed mesh modification method is efficient and effective. The proposed method can be also applied to meshes with different material properties, which is very different with previous work that is only suitable for the meshes with same material property.

This paper proposes an efficient and comprehensive tetrahedral mesh modification method, through which engineers can directly modify meshes instead of models and save time.

IN an address delivered recently before the members of the Library Assistants' Association, Mr. R. T. L. Parr, a Local Government Auditor, revived the suggestion that Public Libraries should be merged in the Education Authority. At first sight the suggestion seems reasonable. Public Libraries are a part and an important part, of the educational machinery of the country; a fact that the public are slow to acknowledge, if one can judge from the meagreness of the funds placed at the disposal of library authorities. Past efforts to increase generally the limited library rate of one penny in the pound have failed signally, while the unlimited general education rate has been rising steadily, without any great protests being made by rate‐payers. Why not, then, adopt Mr. Parr's suggestion, and drop all efforts to promote the new Libraries Bill, and instead favour an Education Bill, in which the necessary reforms for public libraries could be inserted? If this could be done without public libraries being placed under the control of the Board of Education, well and good, but, if not, it is advisable to pause and consider. For many years librarians have been endeavouring to organize their profession, and there is a great danger in the individuality of librarianship being swallowed up in general education. The work of the librarian is quite distinct from that of the teacher, and unless the librarian preserves his individuality he is lost. If public libraries are ever placed under the control of the Government, librarians would be well advised to see that they are specially administered on a professional basis, and not run by educationalists to whom the technique of librarianship is a thing unknown. An example of an attempt to combine librarianship with education is dealt with in the succeeding note. Apart from the idea of placing public libraries under the control of the Board of Education, a state of affairs that we do not recommend, librarians would do well to adopt Mr. Parr's hints, and talk more of the educational value of libraries, for it is in this direction that most influence can be brought to bear upon public thought.

The key objective of this research is to test how two trust dimensions (cognition‐based trust and affect‐based trust) mediate the effects of three personal characteristics (psychological distance, the marketing manager's sales experience, and the marketing manager's relative level of formal education) on the following outcome variables: dysfunctional conflict, functional conflict, and perceived relationship effectiveness.

Drawing on the interaction approach, the paper develops a conceptual framework to better understand the nature of the working relationship between marketing managers and sales managers. In total, it develops and test 13 hypotheses. Partial least squares was used to assess the validity of the measures, and to estimate the structural model. Using a cross‐sectional design, data were collected from 101 marketing managers in Australia.

The hypothesized model has high explanatory power and it was found that both trust dimensions strongly affected all three outcome variables. However, though both forms of trust were positively related to perceived relationship effectiveness, affect‐based trust had the strongest impact on this outcome. The results also confirm that both cognition‐ and affect‐based trust have negative effects on dysfunctional conflict, and strong positive effects on functional conflict. In addition to these new findings, the paper shows that while psychological distance has a strong negative impact on cognition‐based trust, it has no impact on affect‐based trust. Moreover, it was found that when marketing managers had greater levels of sales experience, it increased their affect‐based trust but it had no impact on cognition‐based trust. Finally, the marketing manager's relative level of formal education had no impact on either forms of trust.

This is one of a handful of studies to employ a large‐scale empirical approach to examine the neglected cross‐functional relationship between marketing and sales. Also, it is one of the few studies to examine the effects of cognition‐based trust and affect‐based trust on performance outcomes.

IN the death of Mr. JAMES DUFF BROWN, the library profession loses one of its most striking personalities and librarianship its most powerful influence for progress. Any attempt at present to estimate the extent of his influence upon the modern public library must necessarily be inadequate, because not only are some of the movements he started only beginning to gather force, but his retiring nature made him refrain from labelling many things as his own. With the possible reservation that he was unable to do himself justice on the platform, he was the ideal born public librarian. As an organiser and teacher of librarianship, as a keen and discerning student and critic of tendencies, methods and results, and as an expounder of professional knowledge through the medium of the written page, he was without an equal. Like all pioneers and men of strong opinions, he did not make only friends ; but he had world‐wide friendships, and he forced the attention and respect of all library workers. On another page of this issue an old friend and one‐time colleague of his gives a brief outline of his life and works, and we need not do the same again here. But as his successors in the editorship of THE LIBRARY WORLD, which he founded and edited until a year or two ago, we cannot refrain from adding our tribute to his memory. Representing the best type of efficiency and progress in librarianship, he was a real friend and teacher, and his death leaves a sad gap in our ranks.

THE monumental History of Criticism by Professor Saintsbury, and Mr. Hall Caine's lighter series of studies would be sufficient to put anyone on their guard against accepting as final many of the critical decisions of the important literary reviews. Mr. Caine's book particularly is a revelation of error and spite such as makes one wonder that anonymous literary criticism should be received with toleration by bookmen.

Despite the benefits of computer‐aided design (CAD), its uptake by the garment industry in the UK has been somewhat slow. Many reasons have been suggested for this, one of which is the lack of appropriately skilled designers and pattern cutters. Comments on this situation and describes a garment CAD‐training programme set up at De Montfort University, Leicester. This training programme was used as the basis of an attitude assessment. A questionnaire‐based survey was developed to quantify the designers’ opinions of CAD and specifically whether these opinions were influenced by the designer’s age or prior computing experience.

The primary objective of this research is to test a model examining interpersonal trust between marketing managers and R&D managers during new product development projects.

In this study interpersonal trust as a bi‐dimensional construct with cognitive and affective components is conceptualised. The authors' integrative structural model specifies Weber's structural/bureaucratic dimensions – formalisation and centralisation to predict three communication dimensions, communication frequency, quality, and bi‐directionality. In turn these communication dimensions are used to predict cognition‐based trust, and affect‐based trust. In addition, the paper models the direct effects of the three communication dimensions on a dependent variable – perceived relationship effectiveness. The hypothesised model consists of 16 hypotheses, seven of which relate to the two focal interpersonal trust constructs. The measures were tested and a structural model estimated by using PLS. Data were provided by 184 R&D managers in Australia, reporting on their working relationship with a counterpart marketing manager during a recent product development project.

The hypothesized model has high explanatory power and it was found that both trust dimensions strongly influenced the effectiveness of marketing/R&D relationships during new product development, with cognition‐based trust having the strongest impact. The results also reveal which forms of communication help to build interpersonal trust. The most powerful effect was from communication quality to cognition‐based trust. The next strongest effects were from bi‐directional communication, which was a strong predictor of affect‐based trust, and a somewhat weaker predictor of cognition‐based trust. Interestingly, the direct effects of our three communication behaviours on relationship effectiveness were modest, suggesting that their relationship building effects are largely indirect. Last, it is revealed that bureaucratic means of control on product development projects have mixed effects. As expected, centralisation reduces cross‐functional communication. In contrast, formalisation has a positive effect during product development, as it stimulates both the frequency and bi‐directionality of communication between marketing managers and R&D managers on these projects.

This is the first study to treat interpersonal trust as the focal construct in marketing/R&D relationships during new product development. Moreover, it is the only study of marketing/R&D relationships to conceptualise, measure, and model two underlying dimensions of interpersonal trust (cognition‐based trust, and affect‐based trust). Our study also integrates aspects of Weber's theory of bureaucracy, with interaction theory, and demonstrates the strong links between these theoretical frameworks.
