This paper aims to present the methodology and results of the experimental characterization of three-dimensional (3D) printed acrylonitrile butadiene styrene (ABS) and polycarbonate (PC) parts utilizing digital image correlation (DIC).

Tensile and shear characterizations of ABS and PC 3D-printed parts were performed to determine the extent of anisotropy present in 3D-printed materials. Specimens were printed with varying raster ([+45/−45], [+30/−60], [+15/−75] and [0/90]) and build orientations (flat, on-edge and up-right) to determine the directional properties of the materials. Tensile and Iosipescu shear specimens were printed and loaded in a universal testing machine utilizing two-dimensional (2D) DIC to measure strain. The Poisson’s ratio, Young’s modulus, offset yield strength, tensile strength at yield, elongation at break, tensile stress at break and strain energy density were gathered for each tensile orientation combination. Shear modulus, offset yield strength and shear strength at yield values were collected for each shear combination.

Results indicated that raster and build orientations had negligible effects on the Young’s modulus or Poisson’s ratio in ABS tensile specimens. Shear modulus and shear offset yield strength varied by up to 33 per cent in ABS specimens, signifying that tensile properties are not indicative of shear properties. Raster orientation in the flat build samples reveals anisotropic behavior in PC specimens as the moduli and strengths varied by up to 20 per cent. Similar variations were observed in shear for PC. Changing the build orientation of PC specimens appeared to reveal a similar magnitude of variation in material properties.

This article tests tensile and shear specimens utilizing DIC, which has not been employed previously with 3D-printed specimens. The extensive shear testing conducted in this paper has not been previously attempted, and the results indicate the need for shear testing to understand the 3D-printed material behavior fully.

The purpose of this paper is to introduce the advantages of semantics‐aware representation formalisms in the integration of digital rights management (DRM) infrastructures grounded on heterogeneous formats.

After discussing the notion of semantics‐aware IPR and its relationship with Semantic Web‐style metadata, we exemplify the advantages of adopting it by providing two different use cases. XML‐based DRMLs are mapped with a shared ontology‐based representation in such a way that dependencies between elements can be drawn.

Individual formalisms may take advantage of a semantics‐aware infrastructure to check consistency of DRM policies according to dependencies not explicit in the specification language. On the other hand, distinct formalisms can be integrated with each other according to fine‐grained translation mechanisms.

Inference procedures can pre‐process this knowledge base and derive implicit knowledge that can be used by programming logic in the actual enforcement of DRM policies.

The purpose of this paper is to address a gap in the recent literature on employment of temporary workers by exploring the impact of temporary workers on the perceptions, attitudes and behaviour of permanent staff with particular reference to their implications for patient safety and service quality in hospital accident and emergency departments. The analysis is set in the context of the job demands-resources theory.

The research was undertaken using a case study approach with semi-structured interviews in two London hospitals. Participants included staff from the HR director level, clinical managers and permanent staff who all had an influence in the hiring and management of temporary staff in some way. Transcripts were analysed thematically using an adopted framework approach.

The results indicate that the effect of temporary staff on permanent staff depended on the quality of the “resource”. There was a “hierarchy of preference” for temporary staff based on their familiarity with the context. Those unfamiliar with the department served as a distraction to permanent staff due to the need to “manage” them in various ways. While this was rarely perceived to affect patient safety, it could have an impact on service quality by causing delays and interruptions. In line with previous research, the use of temporary staff also affected perceptions of fairness and the commitment of some permanent staff.

A model developing an approach for improved practice when managing temporary staff was developed to minimise the risks to patient safety and service quality, and improve permanent staff morale.

The review highlights the difficulties that a limited amount of temporary staff integration can have on permanent staff and patient care, indicating that consideration must be placed on how temporary staff are inducted and clarifying expectations of roles for both temporary and permanent staff.

This paper studies the under-researched impact of temporary staff, and, distinctively, staff employed on a single shift, on the behaviour and attitudes of permanent staff. It highlights the need to consider carefully the qualitative nature of “resources” in the job demands-resources theory.

As traditional supply chains are increasingly becoming intelligent with more objects embedded with sensors and better communication, intelligent decision making and automation capabilities, the new smart supply chain presents unprecedented opportunities for achieving cost reduction and enhancing efficiency improvement. The purpose of this paper is to study and explore the currents status and remaining issues of smart supply chain management.

A literature review is conducted to synthesize the earlier work in this area, and to conceptualize and discuss the smart supply chain characteristics. Further, the authors formulate and investigate five key research topics including information management, IT infrastructure, process automation, advanced analytics, and supply chain integration.

Studies in those aforementioned subject fields are reviewed, categorized, and analyzed based on the review questions defined in the study. It is notable that while the topics of converging atoms with digits are increasingly attracting attention from researchers and practitioners alike, there are many more interesting research questions needing to be addressed.

The paper provides original and relevant guidance for supply chain management researchers and practitioners on developing smart supply chains.

The aim of this article is to estimate the impact of faceted classification and the faceted analytical method on the development of various information retrieval tools over the latter part of the twentieth and early twenty‐first centuries.

The article presents an examination of various subject access tools intended for retrieval of both print and digital materials to determine whether they exhibit features of faceted systems. Some attention is paid to use of the faceted approach as a means of structuring information on commercial web sites. The secondary and research literature is also surveyed for commentary on and evaluation of facet analysis as a basis for the building of vocabulary and conceptual tools.

The study finds that faceted systems are now very common, with a major increase in their use over the last 15 years. Most LIS subject indexing tools (classifications, subject heading lists and thesauri) now demonstrate features of facet analysis to a greater or lesser degree. A faceted approach is frequently taken to the presentation of product information on commercial web sites, and there is an independent strand of theory and documentation related to this application. There is some significant research on semi‐automatic indexing and retrieval (query expansion and query formulation) using facet analytical techniques.

This article provides an overview of an important conceptual approach to information retrieval, and compares different understandings and applications of this methodology.

First, the authors analyze the key problems faced by the protection of digital library readers' data privacy and behavior privacy. Second, the authors introduce the characteristics of all kinds of existing approaches to privacy protection and their application limitations in the protection of readers' data privacy and behavior privacy. Lastly, the authors compare the advantages and disadvantages of each kind of existing approaches in terms of security, efficiency, accuracy and practicality and analyze the challenges faced by the protection of digital library reader privacy.

In this paper, the authors review a number of research achievements relevant to privacy protection and analyze and evaluate the application limitations of them in the reader privacy protection of a digital library, consequently, establishing the constraints that an ideal approach to library reader privacy protection should meet, so as to provide references for the follow-up research of the problem.

As a result, the authors conclude that an ideal approach to reader privacy protection should be able to comprehensively improve the security of all kinds of readers' privacy information on the untrusted server-side as a whole, under the premise of not changing the architecture, efficiency, accuracy and practicality of a digital library system.

Along with the rapid development of new network technologies, such as cloud computing, the server-side of a digital library is becoming more and more untrustworthy, thereby, posing a serious threat to the privacy of library readers. In fact, the problem of reader privacy has become one of the important obstacles to the further development and application of digital libraries.
