Abstract
Purpose
This paper aims to print 3D structures from polymers that resist bacterial attachment by reactive jetting of acrylate monomers.
Design/methodology/approach
The first step towards printing was ink development. Inks were characterised to carry out an estimation of their potential printability using the Z parameter to predict stable jetting conditions. Printability conditions were optimised for each ink using a Dimatix DMP-2800, which enabled 3D structures to be fabricated.
Findings
UV photo-initiated polymers, which resist bacterial attachment, were found to be printable using piezo-based inkjet printers. The waveform required for each ink depends on the value of the Z parameter. Once the waveform and the printability parameters were optimised, 3D objects were fabricated.
Research limitations/implications
This methodology has been confirmed as an effective method to 3D print materials that have been demonstrated to be bacteria resistant. However, ink curing depends on modification of some parameters (such as photoinitiator concentration or UV exposure time) which would result in an improvement of the curing process post jetting.
Social implications
The combination of inkjet based 3D printing with new materials resistant to bacterial attachment means the possibility of building customised medical devices with a high level of complexity and bespoke features can be fully realised. The scope and variability of the devices produced will exceed what can be achieved using standard fabrication methodologies and can be applied to reduce the incidence of device associated infections and to address increased morbidity, mortality and health care costs associated with nosocomial infections.
Originality/value
In this paper, the novel use of materials that resist bacterial attachment has been described to build 3D structures using material jetting. Its value lies on the potential impact this methodology could produce in the biomedical device and research fields.

Abstract
People with developmental disabilities have persistent levels of low employment and employment rates among the working-aged disabled are declining (see Bound & Waidmann, 2002). For example, the average employment rate of those graduating with a four-year degree is just under 90% while employment rates for those graduates with a disability hover around 50% (The Center for an Accessible Society, n.d.). Subsequently, people with disabilities often have a difficult time becoming economically self-sufficient (see National Council on Disability, 2000; Sowers, McLean, & Owens, 2002). The Americans with Disability Act (ADA) is one notable attempt to help provide those with a disability to employment access. While the ADA has been a champion of the cause, people with developmental disabilities still face a host of employment-related barriers (e.g., biases associated with the disability) (see DiLeo, 2007; Luecking & Mooney, 2002). Furthermore, while most people have concerns over retirement (e.g., social isolation) those concerns are exacerbated for people with developmental disabilities (see Hodges & Luken, 2006).

Abstract
Purpose
Many employers struggle with how to have a disability disclosure discussion with their employees and job candidates. The primary purpose of this study was to identify issues relevant to disability disclosure discussions. In addition, we explored how simulations, as an educational tool, may help employers and managers.
Design/methodology/approach
Seven participants (four employers and three human resource professionals) took part in this study. We used a qualitative design that involved two focus group discussions to understand participants' experiences of building a simulation training scenario that focused on how to have a disability disclosure discussion. The simulation sessions were audio-recorded and analyzed using an open-coding thematic approach.
Findings
Four main themes emerged from our analysis. Three themes focused on issues that participants identified as relevant to the disability disclosure process, including: (1) creating a comfortable and safe space for employees to disclose, (2) how to ask employees or job candidates about disability and (3) how to respond to employees disability disclosure. A fourth theme focused on how simulations could be relevant as an educational tool.
Originality/value
Developing a simulation on disability disclosure discussions is a novel approach to educating employers and managers that has the potential to help enhance diversity and inclusion in the workplace. Further, the process that we followed can be used as a model for other researchers seeking to develop educational training scenarios on sensitive diversity and inclusion topics.

Abstract
While it has long been established that social factors, such as housing, transportation, and income, influence health and health care outcomes, over the last decade, attention to this topic has grown dramatically. Reforms that promote high-quality care as well as responsibility for total cost of care have shifted focus among health care providers toward upstream determinants of health care outcomes. As a result, there has been a proliferation of activity focused on integrating and aligning social and medical care, many of which depend critically on cross-sector alliances. Despite considerable activity in this area, cross-sector alliances in health care remain largely undertheorized. Both literatures stand to gain from more attention to carefully knitting together the theoretical and management literature on alliances with the empirical, health policy and health services literature on cross-sector alliances in health care. In this chapter, we lay out what exists in the current scientific literature as well as a framework for considering much needed work in this area. We organize the literature and our commentary around the lifecycle of alliances: alliance formation, including factors prompting alliance formation, partner selection, and alliance goals; alliance maturity, including the work of these cross-sector alliances, governance, finance and contracts, staffing structure, and rewards; and critical crossroads, including alliance timelines, definitions of success, and dissolution. We also lay out critical areas for future inquiry, including better theorizing on cross-sector alliances, developing typologies of these cross-sector health care alliances, and the role of policy in cross-sector alliances.

Abstract
AFTER the trenchant paper by Mr. A. O. Jennings, read at the Brighton meeting of the Library Association, and the very embarrassing resolution which was carried as a result, one can only approach the subject of the commonplace in fiction with fear and diffidence. It is generally considered a bold and dangerous thing to fly in the face of corporate opinion as expressed in solemn public resolutions, and when the weighty minds of librarianship have declared that novels must only be chosen on account of their literary, educational or moral qualities, one is almost reduced to a state of mental imbecility in trying to fathom the meaning and limits of such an astounding injunction. To begin with, every novel or tale, even if but a shilling Sunday‐school story of the Candle lighted by the Lord type is educational, inasmuch as something, however little, may be learnt from it. If, therefore, the word “educational” is taken to mean teaching, it will be found impossible to exclude any kind of fiction, because even the meanest novel can teach readers something they never knew before. The novels of Emma Jane Worboise and Mrs. Henry Wood would no doubt be banned as unliterary and uneducational by those apostles of the higher culture who would fain compel the British washerwoman to read Meredith instead of Rosa Carey, but to thousands of readers such books are both informing and recreative. A Scots or Irish reader unacquainted with life in English cathedral cities and the general religious life of England would find a mine of suggestive information in the novels of Worboise, Wood, Oliphant and many others. In similar fashion the stories of Annie Swan, the Findlaters, Miss Keddie, Miss Heddle, etc., are educational in every sense for the information they convey to English or American readers about Scots country, college, church and humble life. Yet these useful tales, because lacking in the elusive and mysterious quality of being highly “literary,” would not be allowed in a Public Library managed by a committee which had adopted the Brighton resolution, and felt able to “smell out” a high‐class literary, educational and moral novel on the spot. The “moral” novel is difficult to define, but one may assume it will be one which ends with a marriage or a death rather than with a birth ! There have been so many obstetrical novels published recently, in which doubtful parentage plays a chief part, that sexual morality has come to be recognized as the only kind of “moral” factor to be regarded by the modern fiction censor. Objection does not seem to be directed against novels which describe, and indirectly teach, financial immorality, or which libel public institutions—like municipal libraries, for example. There is nothing immoral, apparently, about spreading untruths about religious organizations or political and social ideals, but a novel which in any way suggests the employment of a midwife before certain ceremonial formalities have been executed at once becomes immoral in the eyes of every self‐elected censor. And it is extraordinary how opinion differs in regard to what constitutes an immoral or improper novel. From my own experience I quote two examples. One reader objected to Morrison's Tales of Mean Streets on the ground that the frequent use of the word “bloody” made it immoral and unfit for circulation. Another reader, of somewhat narrow views, who had not read a great deal, was absolutely horrified that such a painfully indecent book as Adam Bede should be provided out of the public rates for the destruction of the morals of youths and maidens!

Abstract
“GIVE a dog a bad name and hang him,” is an aphorism which has been accepted for many years. But, like many other household words, it is not always true. Even if it were, the dog to be operated upon would probably prefer a gala day at his Tyburn Tree to being executed in an obscure back yard.

Abstract
THE 31st annual meeting of the Library Association passed off very comfortably at Brighton, and if nothing particularly momentous occurred affecting librarianship, everybody enjoyed the various entertainments and the breezy weather. Brighton certainly deserved the title to breeziness which it claims, because it was stormy nearly every night or early morning during the run of the Conference, and members must be congratulated on the lucky manner in which it was found possible to dodge the showers.
