Personal digital archiving: an analysis of URLs in the .edu domain
Authors: Moulaison Sandy Heather , Corrado Edward M. , Ivester Brandi B. 
Published: March 2017

Purpose
The purpose of this paper is to consider personal digital archiving (PDA) from an academic perspective. Although elements of research data management and personal information management are relevant, it is unclear what is available on university websites supporting PDA. The following question guided the research: where is “PDA” content housed in the top-level .edu domain and what is the format and nature of the content made available?

Design/methodology/approach
This descriptive study analyzed Google hits yielded by searching “PDA” within the .edu domain. Results were analyzed to determine where content was housed and its format and nature. Placement in the domain, delivery methods, topics, and the nature of the most highly ranking Uniform Resource Locators (URLs) were analyzed.

Findings
In the academy, PDA is not exclusively of interest in libraries; not quite half of the .edu URLs (45 percent) pointed to a library site. Scholarly papers were the most returned content, followed by blogs and conferences information. Closer analysis of the top 20 URLs showed that libraries are popular and papers, and blogs continue to be dominant.

Research limitations/implications
The results suggest good PDA practices and recommendations are evolving. Academic librarians should examine these practices, refine them, and make them available and discoverable on the web.

Originality/value
This is the first paper, to the knowledge, to consider PDA content from the perspective of universities and university libraries.
The medium-term prospects for long-term storage systems
Authors: Rosenthal David Stuart Holmes 
Published: March 2017

Purpose
Increasingly, the content that libraries collect is no longer on paper, a long-lived, medium whose technology changes very slowly and with which they have centuries of experience. Instead, it is stored on relatively short-lived digital media whose technology appears to change rapidly and with which they have little history. The paper aims to discuss this issue.

Design/methodology/approach
The storage media industry is highly competitive and is currently evolving rapidly as flash, a solid state medium, displaces spinning disk from many applications. Long-term archival storage is a small part of the total storage market. It typically re-uses media and systems intended for more general bulk storage.

Findings
What are the medium-term prospects for change in this market?

Originality/value
Much of this material has appeared in blog posts and talks aimed at storage experts, such as the recent DARPA workshop on future of storage. It is presented here for a librarian audience with the necessary additional exposition and background.
Disruption be my guide
Authors: O’Connor Steve , Smith Ian , Afzal Waseem 
Published: March 2017

Purpose
The skill set required to be a professional in any profession is inherent in the qualifications required for entrance to that profession. The ability to demonstrate leadership in the middle to upper echelons of that profession is demonstrably different. The School of Information Studies at the Charles Sturt University in Wagga Wagga Australia sought to explore what a postgraduate qualification in the leadership of the profession might look like and what the demand for such a qualification might be. The purpose of this paper is to detail that research effort and the outcomes.

Design/methodology/approach
The study undertook a number of different approaches including engaging in networks of professional colleagues globally and a series of focus groups in Brisbane, Sydney and Melbourne. The outcomes were analyzed in terms of the expectations of what a new degree might contain as well as the enrollment prospects for such a degree.

Findings
There was a strong ground-swell of support for a new degree of Masters of Information Leadership. The combination of subjects from the LIS environment together with subjects from a MBA environment was strongly endorsed. These areas of interest were documented in the paper along with recommendations.

Research limitations/implications
There is a fertile ground for research here in two ways. First, there is much scope for the examination of the course requirements and how they sit in a future work environment. This is especially the case where there is a convergence of the interests of the galleries, libraries, archives and museums sectors. Second, there is much to be done as the authors look at leadership skills sets for future information environments which are highly speculative.

Practical implications
This study has produced a set of requirements for a new Masters of Information Leadership. It is a very useful set of requirements to base future studies. There was also a very strong requirement for real life aspects to such a course rather than theoretical exercises as has been the current academic practice.

Originality/value
This study is quite original as it sought to engage practitioners in different areas and sectors in Australia aiming to ensure that the resulting academic program was closely aligned with practitioner need.
Design and experimental study on the freeform fabrication with polymer melt droplet deposition
Authors: Chi Baihong , Jiao Zhiwei , Yang Weimin 
Published: March 2017

Purpose
3D printing based on additive manufacturing has advantages in manufacturing products with high geometrical complexity. However, there are many limitations to print plastic products with the existing commercial 3D printers. The polymer materials processing industry needs new devices which can satisfy the trend of processing individual units and small batch sizes of plastic parts.

Design/methodology/approach
In this study, a freeform fabrication system with the method of polymer melt droplet deposition is proposed. The performance of this system under different conditions was studied by changing the operating parameters. Furthermore, the dimensional uniformity of droplets and their deposition process are analyzed, and a plastic sample was fabricated with this system as an example.

Findings
The results show a clear correlation between the processing parameters and the droplet diameter. In the experiment for examining the dimensional uniformity of the droplet, the droplets become spindles, and there appears a melt filament between the droplets. The variation of the droplet’s diameters is within 5 per cent. Furthermore, a successfully processed rectangular plastic sample verified the feasibility of this technology for the printing of plastic products.

Originality/value
A freeform fabrication system with polymer melt droplet deposition is proposed, which can process a wide variety of materials in the form of standard granulates like injection molding or extrusion. Based on the principle of droplet deposition, multi-component or colorful materials can be printed.
Effects of 3D-bioplotted polycaprolactone scaffold geometry on human adipose-derived stem cell viability and proliferation
Authors: Mehendale Saahil V. , Mellor Liliana F. , Taylor Michael A. , Loboa Elizabeth G. , Shirwaiker Rohan A. 
Published: March 2017

Purpose
This study aims to investigate the effect of three-dimensional (3D)- bioplotted polycaprolactone (PCL) scaffold geometry on the biological and mechanical characteristics of human adipose-derived stem cell (hASC) seeded constructs.

Design/methodology/approach
Four 3D-bioplotted scaffold disc designs (Ø14.5 × 2 mm) with two levels of strand–pore feature sizes and two strand laydown patterns (0°/90° or 0°/120°/240°) were evaluated for hASC viability, proliferation and construct compressive stiffness after 14 days of in vitro cell culture.

Findings
Scaffolds with the highest porosity (smaller strand–pore size in 0°/120°/240°) yielded the highest hASC proliferation and viability. Further testing of this design in a 6-mm thick configuration showed that cells were able to penetrate and proliferate throughout the scaffold thickness. The design with the lowest porosity (larger strand–pore size in 0°/90°) had the highest compression modulus after 14 days of culture, but resulted in the lowest hASC viability. The strand laydown pattern by itself did not influence the compression modulus of scaffolds. The 14-day cell culture also did not cause significant changes in compressive properties in any of the four designs.

Originality/value
hASC hold great potential for musculoskeletal tissue engineering applications because of their relative ease of harvest, abundance and differentiation abilities. This study reports on the effects of 3D-bioplotted scaffold geometry on mechanical and biological characteristics of hASC-seeded PCL constructs. The results provide the basis for future studies which will use this optimal scaffold design to develop constructs for hASC-based osteochondral tissue engineering applications.
Healing simulation for bond strength prediction of FDM
Authors: Coogan Timothy J. , Kazmer David O. 
Published: March 2017

Purpose
The purpose of this paper is to present a diffusion-controlled healing model for predicting fused deposition modeling (FDM) bond strength between layers (z-axis strength).

Design/methodology/approach
Diffusion across layers of an FDM part was predicted based on a one-dimensional transient heat analysis of the interlayer interface using a temperature-dependent diffusion model determined from rheological data. Integrating the diffusion coefficient across the temperature history with respect to time provided the total diffusion used to predict the bond strength, which was compared to the measured bond strength of hollow acrylonitrile butadiene styr (ABS) boxes printed at various processing conditions.

Findings
The simulated bond strengths predicted the measured bond strengths with a coefficient of determination of 0.795. The total diffusion between FDM layers was shown to be a strong determinant of bond strength and can be similarly applied for other materials.

Research limitations/implications
Results and analysis from this paper should be used to accurately model and predict bond strength. Such models are useful for FDM part design and process control.

Originality/value
This paper is the first work that has predicted the amount of polymer diffusion that occurs across FDM layers during the printing process, using only rheological material properties and processing parameters.
Pre and post processing techniques to improve surface characteristics of FDM parts: a state of art review and future applications
Authors: Chohan Jasgurpreet Singh , Singh Rupinder 
Published: March 2017

PurposeThe purpose of this paper is to review the various pre-processing and post-processing approaches used to ameliorate the surface characteristics of fused deposition modelling (FDM)-based acrylonitrile butadiene styrene (ABS) prototypes. FDM being simple and versatile additive manufacturing technique has a calibre to comply with present need of tailor-made and cost-effective products with low cycle time. But the poor surface finish and dimensional accuracy are the primary hurdles ahead the implementation of FDM for rapid casting and tooling applications.Design/methodology/approachThe consequences and scope of FDM pre-processing and post-processing parameters have been studied independently. The comprehensive study includes dominance, limitations, validity and reach of various techniques embraced to improve surface characteristics of ABS parts. The replicas of hip implant are fabricated by maintaining the optimum pre-processing parameters as reviewed, and a case study has been executed to evaluate the capability of vapour smoothing process to enhance surface finish.FindingsThe pre-processing techniques are quite deficient when different geometries are required to be manufactured within limited time and required range of surface finish and accuracy. The post-processing techniques of surface finishing, being effective disturbs the dimensional stability and mechanical strength of parts thus incapacitates them for specific applications. The major challenge for FDM is the development of precise, automatic and controlled mass finishing techniques with low cost and time.Research limitations/implicationsThe research assessed the feasibility of vapour smoothing technique for surface finishing which can make consistent castings of customized implants at low cost and shorter lead times.Originality/valueThe extensive research regarding surface finish and dimensional accuracy of FDM parts has been collected, and inferences made by study have been used to fabricate replicas to further examine advanced finishing technique of vapour smoothing.
Inkjet and inkjet-based 3D printing: connecting fluid properties and printing performance
Authors: Guo Yang , Patanwala Huseini S. , Bognet Brice , Ma Anson W.K. 
Published: March 2017

Purpose
This paper aims to summarize the latest developments both in terms of theoretical understanding and experimental techniques related to inkjet fluids. The purpose is to provide practitioners a self-contained review of how the performance of inkjet and inkjet-based three-dimensional (3D) printing is fundamentally influenced by the properties of inkjet fluids.

Design/methodology/approach
This paper is written for practitioners who may not be familiar with the underlying physics of inkjet printing. The paper thus begins with a brief review of basic concepts in inkjet fluid characterization and the relevant dimensionless groups. Then, how drop impact and contact angle affect the footprint and resolution of inkjet printing is reviewed, especially onto powder and fabrics that are relevant to 3D printing and flexible electronics applications. A future outlook is given at the end of this review paper.

Findings
The jettability of Newtonian fluids is well-studied and has been generalized using a dimensionless Ohnesorge number. However, the inclusion of various functional materials may modify the ink fluid properties, leading to non-Newtonian behavior, such as shear thinning and elasticity. This paper discusses the current understanding of common inkjet fluids, such as particle suspensions, shear-thinning fluids and viscoelastic fluids.

Originality/value
A number of excellent review papers on the applications of inkjet and inkjet-based 3D printing already exist. This paper focuses on highlighting the current scientific understanding and possible future directions.
Processability of pure Zn and pure Fe by SLM for biodegradable metallic implant manufacturing
Authors: Montani Marco , Demir Ali Gökhan , Mostaed Ehsan , Vedani Maurizio , Previtali Barbara 
Published: March 2017

Purpose
This paper aims to investigate the processability by selective laser melting (SLM) of materials of potential interest for innovative biodegradable implants, pure Fe and pure Zn. The processability of these materials is evaluated with a more established counterpart in permanent implants, stainless steel. In particular, the processing conditions were studied to reduce porosity due to incomplete fusion of the powder.

Design/methodology/approach
In the first phase of the experiments, SLM of AISI 316L was studied through design of experiments method. The study was used to identify the significant parameters in the experimental range and estimate the fluence ranges for pure Fe and pure Zn using the lumped heat capacity model. In the second phase, SLM of pure Fe and pure Zn were studied using estimated fluence ranges. In the final phase, best conditions were characterized for mechanical properties.

Findings
The results showed that complete melting of AISI 316L and pure Fe could be readily achieved, whereas laser melting generated a foam-like porous structure in Zn samples. The mechanical properties of laser melt implant materials were compared to as-cast and rolled counterparts. Laser melted AISI 316L showed superior mechanical performance compared to as-cast and rolled material, whereas Fe showed mechanical performance similar to rolled mild steel. Despite 12 per cent apparent porosity, laser melted Zn exhibited superior mechanical properties compared to as-cast and wrought material because of reduced grain size.

Originality/value
The paper provides key processing knowledge on the SLM processability of new biodegradable metals, namely, pure Fe, which has been studied sparingly, and pure Zn, on which no previous work is available. The results prefigure the production of new biodegradable metallic implants with superior mechanical properties compared to their polymeric counterparts and with improved degradation rates compared to magnesium alloys, the reference material for biodegradable metals.
Rapid prototyping assisted fabrication of customized surgical guides in mandibular distraction osteogenesis: a case report
Authors: Dahake Sandeep W. , Kuthe Abhaykumar M. , Chawla Jitendra , Mawale Mahesh B. 
Published: March 2017

Purpose
The purpose of this paper is to develop a workflow for design and fabrication of customized surgical guides (CSGs) for placement of the bidirectional extraoral distraction instruments (EDIs) in bilateral mandibular distraction osteogenesis (MDO) surgery to treat the bilateral temporomandibular joint ankylosis with zero mouth opening.

Design/methodology/approach
The comprehensive workflow consists of six steps: medical imaging; virtual surgical planning (VSP); computer aided design; rapid prototyping (RP); functional testing of CSGs and mock surgery; and clinical application. Fused deposition modeling, an RP process was used to fabricate CSGs in acrylonitrile butadiene styrene material. Finally, mandibular reconstruction with MDO was performed successfully using RP-assisted CSGs.

Findings
Design and development of CSGs prior to the actual MDO surgery improves accuracy, reduces operation time and decreases patient morbidity, hence improving the quality of surgery. Manufacturing of CSG is easy using RP to transfer VSP into the actual surgery.

Originality/value
This study describes an RP-assisted CSGs fabrication for exact finding of both; osteotomy site and drilling location to fix EDI’s pins accurately in the mandible; for accurate osteotomy and placement of the bidirectional EDIs in MDO surgery to achieve accurate distraction.

Authors: Sing Swee Leong , Yeong Wai Yee , Wiria Florencia Edith , Tay Bee Yen , Zhao Ziqiang , Zhao Lin , Tian Zhiling , Yang Shoufeng 
Published: March 2017

PurposeThis paper aims to provide a review on the process of additive manufacturing of ceramic materials, focusing on partial and full melting of ceramic powder by a high-energy laser beam without the use of binders.Design/methodology/approachSelective laser sintering or melting (SLS/SLM) techniques are first introduced, followed by analysis of results from silica (SiO2), zirconia (ZrO2) and ceramic-reinforced metal matrix composites processed by direct laser sintering and melting.FindingsAt the current state of technology, it is still a challenge to fabricate dense ceramic components directly using SLS/SLM. Critical challenges encountered during direct laser melting of ceramic will be discussed, including deposition of ceramic powder layer, interaction between laser and powder particles, dynamic melting and consolidation mechanism of the process and the presence of residual stresses in ceramics processed via SLS/SLM.Originality/valueDespite the challenges, SLS/SLM still has the potential in fabrication of ceramics. Additional research is needed to understand and establish the optimal interaction between the laser beam and ceramic powder bed for full density part fabrication. Looking into the future, other melting-based techniques for ceramic and composites are presented, along with their potential applications.
Economic crises and the nationalisation of politics
Authors: JURADO IGNACIO , LEÓN SANDRA 
Published: March 2017

AbstractThe literature on party system nationalisation has yet to provide a better understanding of the impact of short‐term factors upon the nationalisation of politics. This article helps to fill this literature gap by analysing the effect of economic conditions on party system nationalisation. The argument is that economic crises will decrease levels of nationalisation by amplifying territorial variation in preferences for redistribution, limiting political parties’ capacity to coordinate divergent interests across districts and triggering the emergence of new political forces. Data on 47 countries for the 1960–2011 period confirm this hypothesis and show that lower economic growth during the years prior to the election is associated with a decrease in levels of party system nationalisation in the next election. The result is robust to variation in the specification of the econometric model and to the use of different measures of nationalisation. Results also show that federal institutions increase the impact of economic conditions on the nationalisation of politics, whereas any moderating effect of electoral system proportionality on the economy is not found.
Women's rights in democratic transitions: A global sequence analysis, 1900–2012
Authors: WANG YI‐TING , LINDENFORS PATRIK , SUNDSTRÖM AKSEL , JANSSON FREDRIK , PAXTON PAMELA , LINDBERG STAFFAN I. 
Published: March 2017

AbstractWhat determines countries’ successful transition to democracy? This article explores the impact of granting civil rights in authoritarian regimes and especially the gendered aspect of this process. It argues that both men's and women's liberal rights are essential conditions for democratisation to take place: providing both women and men rights reduces an inequality that affects half of the population, thus increasing the costs of repression and enabling the formation of women's organising – historically important to spark protests in initial phases of democratisation. This argument is tested empirically using data that cover 173 countries over the years 1900–2012 and contain more nuanced measures than commonly used. Through novel sequence analysis methods, the results suggest that in order to gain electoral democracy a country first needs to furnish civil liberties to both women and men.
Evaluating the Slope‐Area Method to Accurately Identify Stream Channel Heads in Three Physiographic Regions
Authors: Avcioglu Burak , Anderson Christopher J. , Kalin Latif 
Published: March 2017

AbstractEstimation of stream channel heads is an important task since ephemeral channels play a significant role in the transport of sediment and materials to perennial streams. The slope‐area method utilizes digital elevation model (DEM) and related information to develop slope‐area threshold relationships used to estimate the position of channel heads in the watershed. A total of 162 stream channel heads were mapped across the three physiographic regions of Alabama, including the Southwestern Appalachians (51), Piedmont/Ridge and Valley (61), and Coastal Plains (51). Using Geographic Information System and DEM, the local slope and drainage area for each mapped channel head was calculated and region‐specific models were developed and evaluated. Results demonstrated the local slope and drainage area had an inverse and strong correlation in the Piedmont/Ridge and Valley region (r2 = 0.71) and the Southwestern Appalachian region (r2 = 0.61). Among three physiographic regions, the weakest correlation was observed in the Coastal Plain region (r2 = 0.45). By comparing the locations of modeled channel heads to those located in the field, calculated reliability and sensitivity indices indicated model accuracy and reliance were weak to moderate. However, the slope‐area method helped define the upstream boundaries of a more detailed channel network than that derived from the 1:24,000‐scale National Hydrography Dataset, which is commonly used for planning and regulatory purposes.
