Abstract
Purpose
This paper aims to study the effects of part orientation during the 3D printing process, particularly to the case of using continuous digital light processing (cDLP) technology.
Design/methodology/approach
The effects of print orientation on the print accuracy of microstructural features were assessed using microCT imaging and mechanical properties of cDLP microporous scaffolds were characterized under simple compression and complex biaxial loading. Resin viscosity was also quantified to incorporate this factor in the printing discussion.
Findings
The combined effect of print resin viscosity and the orientation and spacing of pores within the structure alters how uncrosslinked resin flows within the construct during cDLP printing. Microstructural features in horizontally printed structures exhibited greater agreement to the design dimensions than vertically printed constructs. While cDLP technologies have the potential to produce mechanically isotropic solid constructs because of bond homogeneity, the effect of print orientation on microstructural feature sizes can result in structurally anisotropic porous constructs.
Originality/value
This work is useful to elucidate on the specific capabilities of 3D printing cDLP technology. The orientation of the part can be used to optimize the printing process, directly altering parameters such as the supporting structures required, print time, layering, shrinkage or surface roughness. This study further detailed the effects on the mechanical properties and the print accuracy of the printed scaffolds.

Abstract
When a library referendum appears on a ballot, it is because a library board wants to “let the voters decide.” There are several different kinds of library referenda, but the most common bond issues seek approval either to finance the purchase or construction of a library building or addition, or to increase a tax rate.

Abstract
Life studies are a rich source for further research on the role of the Afro‐American woman in society. They are especially useful to gain a better understanding of the Afro‐American experience and to show the joys, sorrows, needs, and ideals of the Afro‐American woman as she struggles from day to day.

Abstract
This is a resource guide for librarians who wish to gather books and other materials to use in promoting National Women's History Week or, as it will be soon, National Women's History Month. The emphasis is on history rather than on current women's issues. Most of the materials cited have appeared within the past ten years, but a few important older works are included as well.

Abstract
Purpose
This paper seeks to illustrate the instrumental role of reporter Nell Nelson in beginning a national labor reform movement resulting in improved working conditions for women and children in the USA.
Design/methodology/approach
Drawing on archival newspaper clippings, original scrapbooks kept by prominent Chicago figures of the time, US census records, and other labor history resources, the paper synthesizes heretofore‐disparate sources to provide a more complete picture of the cause‐and‐effect nature of Nelson's Chicago Times “City slave girls” series.
Findings
The research concludes that Nelson was an instrumental force in the formation of over ten advocacy organizations that worked to transform the way women and children in the USA were treated in the workplace and was instrumental in securing legislative reforms.
Originality/value
This is the first paper to explore the role played by Nell Nelson in securing labor reforms, thus, contributing to a more complete understanding of management history.

Abstract
This article examines the national and international connections made by women graduates of the School of Home Science in their efforts to develop the scholarly expertise and professional capacity that would enable them to pursue academic careers and to improve the position of women in universities. It argues that despite the obstacles, many women were able to pursue academic pathways and to establish their own authority. By undertaking a transnational analysis, this article examines webs of influence that linked women scholars in New Zealand, Australia, Canada and the United States as well as those in the so called “centre” (Europe and the United Kingdom). It explores the networks formed by a select number of middle class women ‐ scholars such as Ann Gilchrist Strong, Elizabeth Gregory and Neige Todhunter ‐ as they attempted to expand the range of their scholarly work beyond national borders. It considers the influence of appointments of women academics from the United States and the United Kingdom on; the significance of post graduate study opportunities for home science graduates; and the role of scholarships and awards that enabled two way travel between the southern and northern hemispheres. A number of tensions are evident in the way women scholars located their work in new and emerging fields of academic knowledge within the university. This article explores interrelationships between women academics and graduates from the School of Home Science at the University of Otago and academic women in the United Kingdom and the United States. The final section of the paper examines the academic and scholarly life of Catherine Landreth who exemplifies the experience of a select group of women who gained personally, culturally and professionally from their international opportunities, experiences and networks. It considers Landreth’s transnational travels in search of scholarly expertise, the influence of her personal and professional networks, the significance of her pioneering work in the emerging field of early childhood education and the constraints experienced in a highly gendered academic enclave. To begin however it gives a brief overview of the introduction of Home Science at the University of New Zealand and the influence of initial international appointments on the expansion of women’s academic work at the University of Otago.

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
We've been living in a homogenous world, you know a world centered on and seen through the language perceptions of men. The consequences of this for everything that we take for granted, for all our assumptions are very deep. Feminism, in the sense I use it, is a radical complexity thought in the process of transforming itself. It is a kind of breaking open of not only the oversimplification but of the lies and the silence in which so much of human experience has been cloaked. Too much has been left out, too much has been unmentioned, too much has been made taboo. Too many connections have been disguised or denied. (Interview with Adrienne Rich, Christopher Street, Jan. 1977, pp. 9–16.)
