This paper aims to investigate the applicability of 3D-printed molds to be used as a substitute for photolithography in the formation of polymer-based stamps. It proposes leveraging 3D printing as a rapid prototyping tool to be applied to microfluidic fabrication.

Different designs are created using computer-aided design (CAD) software and printed via Makerbot 3D printer. The molds serve as negative reliefs for a PDMS stamp. The stamp is used to apply paraffin wax to chromatography paper, creating hydrophobic barriers and hydrophilic channels. The minimum functional channel widths and barrier widths are determined for the method.

The method is demonstrated to be effective for bypassing the more cost-prohibitive photolithography approach for rapid paper microdevice fabrication. This approach produces functional channels that can be used for on-chip analytical assays. The minimum functional barrier widths and minimum functional channel widths are in good agreement with other published methods for paper-based microchannel fabrication.

The approach cannot generate the high-resolution structures possible with photolithography. Therefore, if higher resolutions are needed for a particular application, this approach is not the best.

The simplicity of the approach introduces an affordable method to create disposable devices that can be used at the point of testing.

The paper satisfies a need for inexpensive, rapid prototyping of paper-based devices. The method is simple and can be used as a tool for introducing labs to microfluidics research.

To outline the multiple ways in which animals are inserted into sporting practices, outline historical and contemporary approaches to studying human–animal sporting practices, and advocate for the centering of sociological problems in human–animal research in sporting contexts and cultures and for considering such problems in relation to environmental issues.

In the first part of the chapter, conceptual differentiation of animals in the animal–sport complex is presented. Subsequently, studies of interspecies sport are reviewed with reference to the “animal turn” in the literature. In the second part, a critique is presented relating to: (1) the privileging of companion animals, especially dogs and horses, which overlooks the multiple ways animals are integrated into (multispecies) sport; (2) micro-sociological and insider ethnographies of companionship displacing of sociological problems in favor of relationship perspectives; and (3) the environment as absent from analysis. The conclusion offers implications for understanding multispecies sport and the environment.

I chart a general shift in emphasis and focus from animals as an “absent presence” in pursuit of sociological knowledge toward a clearly defined focus on interspecies sport as a field of research characterized by investigations of relationships with companion animals through the “animal turn.”

The focus on companion species means other animals (i.e., noncompanions) are understudied, big picture sociological questions are often sidelined, environmental concerns marginalized, and sociological understanding of the environment more generally is either ignored or reduced to a conduit of human–animal interactions.

Public education in the United States is White, middle class, and urban/suburban normed. However, in the past decade, national population trends show an increase in minority populations, particularly in the southeastern United States. This trend has resulted in a cultural mismatch between teachers who are not trained in strategies that are responsive to the needs of a diverse student population. Novice teachers in a rural school district in eastern North Carolina participated in a study to examine the degree to which they were prepared to successfully interact with their culturally diverse student populations through the lens of culturally relevant classroom management (CRCM), based on their training at either historically White (HWIs) or Black (HBCUs) postsecondary institutions. As part of this larger study, we found that teachers trained at HWIs, although well-intentioned, enter the classroom far less prepared than their HBCU-trained counterparts. However, for both groups of novice teachers, intercultural interactions earlier in their lives seem to have a greater influence than institutional effects on effective, culturally relevant classroom management practices.

AT the time of writing (Autumn 1966), those who are concerned with technical college libraries stand at a very interesting stage in the development of those services. I was reminded of this fact the other day when I was lunching with one of the College Principals who had been concerned with the ATI Memorandum on College Libraries in 1937. (That, as you may know, was a very forward‐looking document and outlined objectives, not all of which have yet been attained.)

The National Film Archive (NFA) was established in 1935 to collect and preserve film. In the preceding decades the new medium was beginning to make its impact on society and the NFA was faced with the formidable task of preserving the nation's moving image heritage. With the passage of time more formats were developed and production increased, creating problems for the NFA and the other collections, especially regional and special archives, which had been established. As film, television and video grew in importance demands for greater access to archives and libraries increased as new user groups challenged the status quo. This paper reviews the trends in the collection and use of moving images during the fifty year period between 1935 and 1985, concentrating on non‐fiction material.

.Counter Competition. SUPERMARKETS and private shopkeepers battle for business in every High Street. In all shopping centres the private trader competes for the customer's cash with chain and departmental stores. He finds life increasingly difficult in face of rising overheads and shrinking profit margins.

THE American magazine Business Week recently dealt with the problem of work study in white collar areas and in the course of the article made the following comment: ‘The real impact of computer technology on work measurement and performance standards will come when it can take over more of the functions of the industrial engineer.’
