Abstract
A solid freeform fabrication (SFF) technique is described where powder is deposited layer‐by‐layer using electrophotographic printing. In the electrophotography process, powder is picked up and deposited using an electrostatically charged surface. A test bed was designed and constructed to study the application of electrophotography to SFF. It can precisely deposit powder in the desired shape on each layer. A polymer toner powder was used to build small components by thermally fusing each layer of printed powder using a hot compaction plate. The feasibility of 3D printing using this approach was also studied by printing a binder powder using electrophotography on to a part powder bed.

Abstract
Pictures are routinely identified as possible sources for researching history yet they are widely either neglected or underused. This article explores the use of pictorial materials, in particular photographs, in historical analysis. It describes some common, or standard, uses of photographs in historical writing, and critically discusses them. It identifies and examines methodological and ethical issues in using photographs as evidence. And it draws on a current project which is using a rich body of photographs as an integral part of its analysis of the history of one educational institution to explore these issues

Abstract
Scholars have argued that different forms of proactive behaviors (e.g., career initiative, feedback seeking, and taking charge) all involve employees’ self-initiated and future-focused efforts to bring about change in a situation (Parker et al., 2006). There are at least three important elements that define proactivity: future-focus, change-orientation, and self-initiation (Frese & Fay, 2001; Parker et al., 2006). First, proactive behavior is future-focused, which means that this action is targeted at anticipated problems or at opportunities with a long-term focus. Second, proactive behavior is change-oriented, involving not just reacting to a situation but being prepared to change that situation in order to bring about a different future. Third, and underpinning the prior two elements, proactive behavior is self-initiated, which means that employees initiate a proactive goal without being told to, or without requiring explicit instructions from supervisors. Accordingly, proactivity has also been conceived of as a process in which employees generate and implement, under their own direction, a proactive goal to bring about a different future (Bindl, Parker, Totterdell, & Hagger-Johnson, 2012; Frese & Fay, 2001; Grant & Ashford, 2008).

Abstract
Few issues in recent times have so provoked debate and dissention within the library field as has the concept of fees for user services. The issue has aroused the passions of our profession precisely because its roots and implications extend far beyond the confines of just one service discipline. Its reflection is mirrored in national debates about the proper spheres of the public and private sectors—in matters of information generation and distribution, certainly, but in a host of other social ramifications as well, amounting virtually to a debate about the most basic values which we have long assumed to constitute the very framework of our democratic and humanistic society.

Abstract
The modern concept of labor hoarding emerged in early 1960s, and soon became a standard part of mainstream economists’ explanation of the working of labor markets. The concept represents the convergence of three important elements: an empirical finding that labor productivity was procyclical; a framing of this finding as a “puzzle” or anomaly for the basic neoclassical theory of the firm, and a proposed resolution of the puzzle based on optimizing behavior of the firm in the presence of costs of hiring, firing, and training workers. This paper recounts the history of each of these elements, and how they were woven together into the labor hoarding concept. Each history involves people associated with various research traditions and motivated by an array of questions, many of which were unrelated to the questions that the modern labor hoarding concept was ultimately created to address.

Abstract
Purpose
This paper presents the research findings of the “Syrian New Scots’ Information Literacy Way-finding practices” research project, funded by the Information Literacy Group of the Chartered Institute of Library and Information Professionals. The purpose of this paper is to explore the information needs of “Syrian New Scots” (the preferred name for refugees in Scotland), their habitual and adaptive information literacy practices and the barriers and enablers they encounter within their new socio-cultural setting via their interactions with people, tools and processes.
Design/methodology/approach
Primary data were collected via interviews with three Local Authority Leads for Syrian Resettlement and focus groups with Syrian New Scots in three geographical locations in Scotland: two rural areas and one urban. Syrian research subjects were also involved in a drawing exercise that helped to contextualise the findings.
Findings
The main information needs expressed by participants revolved around the learning of English language which was linked to addressing health-related information needs, well-being and community engagement. All participants also highlighted the issue of socio-cultural differences in fulfilling everyday life information needs (such as health and housing). Information provision to Syrian New Scots requires a more structured process that acknowledges personalised information needs and it is tailored to the different stages of the adaptation process. The findings suggest that the “ways of knowing” that Syrian refugees bring with them are converging information experiences of past and new knowledge structures gained via different socio-cultural and migration experiences.
Originality/value
The research findings of this project will be of interest to local and regional support organisations and community volunteer groups who contribute to the social well-being and social integration of Syrian refugees. In addition, they may be of interest to public libraries due to their role as centres for educational and cultural orientation sessions, and as places of support for newly settled Syrian refugees and the communities that embrace them.

Abstract
When a community of fifty thousand people have all their eggs in two baskets and one is dropped it is a serious matter, not only for the industry concerned but for all who live upon it indirectly. Especially is this so when geographical isolation makes it impossible for the worker to transfer to other employment when his job fails. Jersey, the largest of the Channel Islands, has experienced the slings and arrows of outrageous fortune on several occasions since liberation from German thraldom revived both hope and opportunity to make up the loss and deprivations of those five weary years. It has not been all plain sailing. In addition to starved soil, depreciated and often ruined buildings, and other drawbacks experienced in common with agriculturalists in other countries, Jersey has had her own problems, chief of which has been the Colorado Beetle. A legacy of German neglect, this pest had established itself so widely on the island that the first crop of potatoes raised after Liberation was not safe to be imported to England, and was therefore sold to France. This was unsatisfactory from a financial point of view, and so the following year the crop was taken up by the Army of Occupation on the Rhine. By the season of 1947 sufficient progress had been made in the elimination of the beetle to allow crops from unaffected areas to enter England, and once again normal trading, in so far as controls of all kinds would permit, was resumed. Jersey is a two‐crop island and potatoes must be succeeded by tomatoes if the highly‐priced land is to be made to pay for itself. So while the first of these crops was just paying its way, the second was expected to clear costs and to make the farmer or grower his profit. When it looked as though this might be possible this season the islanders came up against another, and quite unexpected, snag—too much fine weather. It may sound ungrateful to say this, in view of the many thousands of visitors which the continued sunshine brought to the island, and actually the farmer was glad enough to have the fine dry days in which to get his work done. But it reacted against him by bringing on his fruit too early and all at once, which meant that it arrived upon the market when there were still quantities of Guernsey and English glasshouse tomatoes as well as Dutch and other foreign‐grown available, and Jersey shipments were so heavy that they caused a glut. Where a grower is situated near an industrial or residential area he has the opportunity in such circumstances of disposing of at least part of his fruit as it ripens, by retail or direct sale, even if only to passers‐by. But on an island where three‐quarters of the population is engaged in growing tomatoes or in handling them in some way, everyone is soon sick of the sight of them and it is impossible to give them away if a glut occurs. That happened this summer when on two occasions of several days each it was necessary for the authorities to prohibit picking the fruit. The island crop must be gathered when it is first turning from green to yellow in order to allow it to ripen during the process of grading, packing and transit by sea and rail to the wholesale distributors, and thence via the retailer to the ultimate consumer. Therefore, when the position arose that the distributors could handle no more of the 12 lb. trays and the order went out that no more fruit should be picked there were many thousands of these containers en route between the farmsteads and the ships which awaited them at the quayside. All this fruit became useless within a matter of hours, and the only thing to do with it would have been to drive to a disused quarry or to the seashore and dump the lot, had it not been for the local canning factory. Jersey Canners Ltd. has been in existence from the early days of this century, but were not in a position to handle a great deal of produce until this year, when they were taken under the wing of the National Canning Co. Ltd., with Mr. S. W. Smedley in control. A great deal of this surplus was therefore taken over by this factory and converted into puree and sauce, as well as being canned whole. The development and processing of the fruit in this way is a story of its own, but perhaps the most interesting feature of this factory's work is that of the preparation of tomato juice on a commercial scale. This latter process, as apart from the more usual methods of dealing with the tomatoes, was due to the foresight of Mr. Smedley, who early this year visualised the possibilities of utilising any surplus crop and thus, when the position arose, was able to put upon the market the first tins of pure tomato juice ever to have been produced commercially outside of the U.S.A. To do this it was necessary to install an American pre‐heating vacuum pasteurising machine, but all other necessary mechanical appliances are British. These consist of endless belting, elevator, seamer, rotary cooker and cooler, and labelling machines. On arrival at the factory the fruit is conveyed from the lorries by roller belt to the elevator leading to the rotary washing machines. After thorough cleansing it passes on to a sorting belt, where diseased and immature samples are discarded and the remainder are stemmed by a small staff of women. The fruit is then fed automatically to the chopping machine and after treatment it experiences its first heating in the pasteuriser. This prepares it for the actual juice extraction, which is carried out in a machine which discards the cores, skins and seeds, and pumps the pure juice back into the pre‐heater, where it is pasteurised at a temperature of 180 degrees. After passing through this process the juice flows to the automatic filling machine, which handles 60 cans per minute, and so to the seamer, where the lids are sealed down before the cans pass into the cooker. This is an automatic rotary machine which ejects the cans after 15 minutes at a temperature, of 212 degrees. They are then cooled off for ten minutes in a cold water tank and set aside for labelling. The purely mechanical processes here described appear to make the preparation of tomato juice a simple matter. Actually, however, it is one requiring much investigation into the problems of fermentation, colouring, etc., beforehand, and careful attention to temperatures and timing of the various processes while in operation. Cooking of the juice is effected by steam with the cans in a vacuum, this process conserving the vitamin contents and the natural colouring of the juice, two most important features which would be sacrificed if the liquid was exposed to the light at a high temperature. The plant at present installed at Messrs. Jersey Canners Ltd. is capable of handling up to four tons of fruit per hour and has been turning out about 30,000 cases of assorted 16 oz. and 32 oz. cans per month during the height of the rush period. At that time the factory was working right round the clock with the aid of volunteer workers, many of whom put in time at night after their own day's work, in order to save as much as possible of the crop that would otherwise have been thrown away.

Abstract
Proactivity is a type of goal-directed work behavior in which individuals actively take charge of situations to bring about future change in themselves or their organization. In this chapter, we draw on goal-regulation research to review conceptual and empirical evidence that elucidates some of the complex links of affective experience and employee proactivity. We identify the different ways in which affective experience influences different stages of proactivity, including employees’ efforts in setting a proactive goal (envisioning), preparing to implement their proactive goal (planning), implementing their proactive goal (enacting), and engaging in learning from their proactive goal process (reflecting). Overall, our review suggests an important, positive role of high-activated positive trait affectivity and moods in motivating proactivity across multiple goal stages, as compared to low-activated positive affectivity and moods. The role of negative affect is mixed, and likely depends on both its valence and the stage of proactivity that is being considered. We identify a lack of research on the role of discrete emotions for employee proactivity. We discuss future avenues for research, particularly the roles of intra- and inter-personal emotion regulation for proactivity and of affective embeddedness of proactive processes in the social environment of organizations.
