Abstract

THE new President of the Library Association, a handsome portrait of whom appears in the December Library Association Record, brings to the office the influences of a career of fine public service. We, in common with every journal that speaks to and for librarians, assure him of loyalty and congratulate ourselves on this addition to the roll of distinguished men who have served librarianship. The Record is wise in reminding us that we are more than a librarians' association and the regular election of men of affairs as presidents is a policy that used to be followed and should now be continued. The policy need not exclude in normal circumstances an alternate librarian president.

Abstract

THE effective little conference of the London and Home Counties Branch of the Library Association at Brighton gave clear proof of the value of and desire for such gatherings. This experience, we are confident, will be understood by our Council and a national conference should be possible in 1946. At Brighton, amongst many good things, from the public lecture by Charles Morgan to the excellent symposium by the Service members, there was the important statement by Mr. Goldsack, Chairman of the National Book League and a well‐known publisher, on the state of British stocks of books. A census made by publishers and booksellers had revealed that some 50,000 basic books, which are required continuously by libraries, schools and the general reading world, are out‐of‐print. It may be recalled that forty years ago James Duff Brown asserted “of real, living works of literary and human interest, there are perhaps not more than 20,000 in the English language,” and if more than twice that number of books are unavailable the condition would seem to be parlous. Of course the quotation we have made is not acceptable today nor is the statement unqualified in the Berwick Sayers' editions of Brown's Manual, but Mr. Goldsack's figures give us furiously to think. We are bound to keep in every town and county a representative collection of books of every age and we do know that there is the insistent demand for current books; for some readers, indeed, this means current fiction; lacking that we are labelled as “useless” by the most vocal part of the community of readers.

Abstract

LIBRARIES, in common with all other public institutions, must be faced with the uncertainty that arises from the inconclusive results of the recent General Election. We are not intimately concerned with parties and it is held that librarians should eschew them altogether as they have duties to, are the servants of, all. This consideration applies more to the public librarian than to the special one. Be that as it may, the change must postpone, we imagine, our chances of the new Public Libraries Act, because a new general election is probable in a very short time. Meanwhile, there is always uncertainty as to public expenditure and, although we do not expect anything drastic, it is hardly likely that our centenary year will see the beginnings of the library progress for which some had hoped. Most local rate‐budgets have, fortunately, been fixed by now.

Abstract

Eating and drinking temporarily suppress the desire to eat and/or the desire to drink. These satiating effects are learned responses to complex patterns of stimulation from available foods and drinks and the external and internal environments. Considers the possible roles of physiological actions of ingested foods and beverages in the signals from the body which contribute to the sense of repletion, the dulling of hunger and the quenching of thirst.

Abstract

FOR public libraries the Ministerial statement that proposals for the future of local government will be laid before Parliament before October may prove to be most significant. We say may, because such preliminaries usually raise undue expectations. Meanwhile during the summer speculation may range over the public library possibilities of the situation. Will the known blue‐prints made for us come into the picture: the masterly, and at that time far too advanced, pattern in the McColvin Report, already fourteen years old, and the older Ministry of Reconstruction Report, made as the First World War was closing, which would have given libraries, willy‐nilly, to the Education Committee? Will the present L.A. plan, which everyone knows, affect matters? Will public libraries come in at all? Local Government, as at present organized, does work, even if the machinery creaks with too many uncontrolled bodies intervening in every part, too much remote control, and, conversely, too little co‐operative organization, too many jealousies, boundary graspings, disputes and much expensive, unnecessary litigation. That public librarians can provide an acceptable solution for their own admittedly limited field will, alas, not occur to many authority minds. In the reconstruction of the patchwork now existing our library leaders must be alert to prevent complete indifference to library needs and possibilities. We feel sure they will be. That vigilance will be necessary even if, as we suspect from the tendency of the times, what will be proposed is not likely to produce radical redistributions and changes. The counties, municipal corporations, and the urban districts together form a formidable combination and, we think, can prevent further encroachments on their areas and increased restrictions of their powers. The way may be somewhat plainer before the L.A. Annual General Meeting is held in September, but the announcement we are discussing came later than the printing of the outline programme of the Conference which is inserted in the May L.A. Record.

Abstract

Purpose

The purpose of this study is to examine how customers’ perceptions of brands’ social media interactivity impact customer engagement behaviors (CEBs) (e.g. customer purchases, referrals, influence and knowledge) while accounting for the moderating role of brand type and social media platform.

Design/methodology/approach

Two separate online surveys (Study 1 (N1) = 341, Study 2 (N2) = 183) were conducted to measure the constructs of interest. Regression analyzes tests research hypotheses; PROCESS Model 1 was used to test the moderating roles of brand type and platform. Further, the pick-a-point approach (i.e. spotlight analysis) was used to probe the interaction terms.

Findings

The results indicate that when customers perceive a brand to be highly interactive on social media (vs inactive), they are more willing to buy brand offerings, refer the brand in exchange for monetary incentives, inform their family and friends about the brand on social media and provide feedback and suggestions for improving the brand. Furthermore, the positive impact of perceived social media interactivity on customer purchases, referrals, influence and knowledge varies across brand and social media platform types.

Research limitations/implications

Online surveys using convenience samples were conducted to assess the constructs of interest. Archival data may provide an avenue for further insight. Future research may be able to track actual online customer behavior using such data. Further, researchers are encouraged to corroborate the results found here over time as the winds of social media shift to new platforms.

Practical implications

The results suggest that interacting on social media encourages customers to contribute to brand value directly (through purchasing) and/or indirectly (through referring, influencing and suggesting). While all brands may leverage social media activity for success, the positive impact of perceived social media interactivity on CEBs is particularly impactful for non-global 500 brands. The results also indicate that customers are more willing to add value to the brand through purchases and suggestions when they perceive the brand to be highly interactive on both social media networking sites and the brand’s website. However, they are more willing to promote this brand and influence their social networks about it only when they perceive the brand to be highly (vs less) interactive on its own website.

Originality/value

This study examines the novel issue of the impact of perceived social media interactivity on different CEBs while accounting for the moderating role of the brand and platform used by customers. The results provide value in better understanding the levers through which social media affects performance.

Abstract

Purpose

Social media facilitates the communication and the relationship between healthcare professionals and patients. However, limited research has examined the role of social media in a physicians' online return. This study, therefore, investigates physicians' online economic and social capital return in relation to physicians' use of social media and consumer engagement.

Design/methodology/approach

Using ordinary least squares (OLS) regression with fixed effects (FE) and panel data collected from Sina Weibo and Sina Health, this study analyzes the impact of physicians' social media use and consumer engagement on physicians' online return and the moderation effect of professional seniority.

Findings

The results reveal that physicians' use of social media and consumer sharing behavior positively affect physicians' online economic return. In contrast, consumer engagement positively impacts physicians' online social capital return. While professional seniority enhances the effect of physicians' social media use on online economic return, professional seniority only enhances the relationship between consumers' sharing behavior to the posts and physicians' online social capital return when professional seniority comes to consumer engagement.

Originality/value

This study reveals the different roles of social media use and consumer engagement in physicians' online return. The results also extend and examine the social media affordances theory in online healthcare communities and social media platforms.

Abstract

Purpose

AlSi10Mg alloy is commonly used in laser powder bed fusion due to its printability, relatively high thermal conductivity, low density and good mechanical properties. However, the thermal conductivity of as-built materials as a function of processing (energy density, laser power, laser scanning speed, support structure) and build orientation, are not well explored in the literature. This study aims to elucidate the relationship between processing, microstructure, and thermal conductivity.

Design/methodology/approach

The thermal conductivity of laser powder bed fusion (L-PBF) AlSi10Mg samples are investigated by the flash diffusivity and frequency domain thermoreflectance (FDTR) techniques. Thermal conductivities are linked to the microstructure of L-PBF AlSi10Mg, which changes with processing conditions. The through-plane exceeded the in-plane thermal conductivity for all energy densities. A co-located thermal conductivity map by frequency domain thermoreflectance (FDTR) and crystallographic grain orientation map by electron backscattered diffraction (EBSD) was used to investigate the effect of microstructure on thermal conductivity.

Findings

The highest through-plane thermal conductivity (136 ± 2 W/m-K) was achieved at 59 J/mm3 and exceeded the values reported previously. The in-plane thermal conductivity peaked at 117 ± 2 W/m-K at 50 J/mm3. The trend of thermal conductivity reducing with energy density at similar porosity was primarily due to the reduced grain size producing more Al-Si interfaces that pose thermal resistance. At these interfaces, thermal energy must convert from electrons in the aluminum to phonons in the silicon. The co-located thermal conductivity and crystallographic grain orientation maps confirmed that larger colonies of columnar grains have higher thermal conductivity compared to smaller columnar grains.

Practical implications

The thermal properties of AlSi10Mg are crucial to heat transfer applications including additively manufactured heatsinks, cold plates, vapor chambers, heat pipes, enclosures and heat exchangers. Additionally, thermal-based nondestructive testing methods require these properties for applications such as defect detection and simulation of L-PBF processes. Industrial standards for L-PBF processes and components can use the data for thermal applications.

Originality/value

To the best of the authors’ knowledge, this paper is the first to make coupled thermal conductivity maps that were matched to microstructure for L-PBF AlSi10Mg aluminum alloy. This was achieved by a unique in-house thermal conductivity mapping setup and relating the data to local SEM EBSD maps. This provides the first conclusive proof that larger grain sizes can achieve higher thermal conductivity for this processing method and material system. This study also shows that control of the solidification can result in higher thermal conductivity. It was also the first to find that the build substrate (with or without support) has a large effect on thermal conductivity.

Abstract

Purpose

The quality and properties of Inconel 718 (IN718) from selective laser melting (SLM), a major additive manufacturing (AM) process, have been studied extensively. Among all aspects of quality, relative density (RD) is most widely investigated, and it significantly affects the mechanical properties of SLM-ed materials. This study aims to develop robust RD prediction models based on the data accumulated in literature using machining learning approaches.

Design/methodology/approach

By mining the literature of SLM-ed IN718, a comprehensive data set is created, which consists of the four major process parameters of laser power, scan speed, hatch spacing, layer thickness and RD data. A back propagation neural network (BPNN) model, along with its two optimized models: genetic algorithm (GA) optimized BPNN (GA-BPNN) and adaptive GA optimized BPNN (AGA-BPNN) models are created for predicting the RD of SLM-ed IN718, and their prediction performances are compared.

Findings

Overall, satisfactory prediction accuracies are obtained – the R2 values of the built BPNN, GA-BPNN and AGA-BPNN models are 73.5%, 75.3% and 79.9%, respectively. This also shows that by incorporating the optimization technique, the prediction accuracy of BPNN is improved and AGA-BPNN has the highest accuracy. Moreover, SLM experiments are conducted to test the model predictability. It is found that the predictions generally agree well with the experiment data, and the order of the model prediction accuracies is consistent with that based on the literature data.

Originality/value

This research highlights that by mining literature data, prediction models of RD of SLM-ed IN718 can be obtained with satisfactory performance, which consider more process parameters and cover wider parameter ranges than any individual studies, in a cost-effective manner.
