Authors: C. Dearborn Carly , J. Barton Amy , A. Harmeyer Neal 
Published: March 2014

Purpose
– The purpose of this case study is to discuss the creation of robust preservation functionality within PURR. The study seeks to discuss the customization of the HUBzero platform, composition of digital preservation policies, and the creation of a novel, machine-actionable metadata model for PURR's unique digital content. Additionally, the study will trace the implementation of the Open Archival Information System (OAIS) model and track PURR's progress towards Trustworthy Digital Repository certification.

Design/methodology/approach
– This case study discusses the use of the Center for Research Libraries Trusted Repository Audit Checklist (TRAC) certification process and ISO 16363 as a rubric to build an OAIS institutional repository for the publication, preservation, and description of unique datasets.

Findings
– ISO 16363 continues to serve as a rubric, barometer and set of goals for PURR as development continues. To become a trustworthy repository, the PURR project team has consistently worked to build a robust, secure, and long-term home for collaborative research. In order to fulfill its mandate, the project team constructed policies, strategies, and activities designed to guide a systematic digital preservation environment. PURR expects to undertake the full ISO 16363 audit process at a future date in expectation of being certified as a Trustworthy Digital Repository. Through its efforts in digital preservation, the Purdue University Research Repository expects to better serve Purdue researchers, their collaborators, and move scholarly research efforts forward world-wide.

Originality/value
– PURR is a customized instance of HUBzero®, an open source software platform that supports scientific discovery, learning, and collaboration. HUBzero was a research project funded by the United States National Science Foundation (NSF) and is a product of the Network for Computation Nanotechnology (NCN), a multi-university initiative of eight member institutions. PURR is only one instance of a HUBzero's customization; versions have been implemented in many disciplines nation-wide. PURR maintains the core functionality of HUBzero, but has been modified to publish datasets and to support their preservation. Long-term access to published data are an essential component of PURR services and Purdue University Libraries' mission. Preservation in PURR is not only vital to the Purdue University research community, but to the larger digital preservation issues surrounding dynamic datasets and their long-term usability.
Evidence-based practice and web usability assessment
Authors: Cervone Frank 
Published: March 2014

Purpose
– Issues related to usability and creating effective and engaging user experiences on the internet continue to vex libraries and information agencies. Many organizations still do not have an on-going, sustainable usability assessment program in place. This should be a cause for concern because usability programs serve as a quality-control check on our ability to provide quality information. This is why evidence-based information practice is so important as a fundamental building block of a usability assessment plan. This paper aims to address these issues.

Design/methodology/approach
– Through a review of the basic principles of evidence-based practice, the author puts into context how a web assessment methodology could be put in place at a library or information organization.

Findings
– Using the principles of evidence-based practice, as well as a user-centered design perspective, can greatly enhance the ability of libraries and information organizations to develop effective web usability assessment programs.

Originality/value
– While there has been a significant body of work in library and information science related to implementing evidence-based practice (EBP), there has been little specifically written about applying EBP to web usability assessment. This article fills that gap in the literature.
Close to CAD model curved-form adaptive slicing
Authors: Hayasi Mohammad , Asiabanpour Bahram 
Published: March 2014

Purpose
– The main aim of this study is to generate curved-form cut on the edge of an adaptive layer. The resulting surface would have much less geometry deviation error and closely fit its computer aided design (CAD) model boundary.

Design/methodology/approach
– This method is inspired by the manual peeling of an apple in which a knife's orientation and movement are continuously changed and adjusted to cut each slice with minimum waste. In this method, topology and geometry information are extracted from the previously generated adaptive layers. Then, the thickness of an adaptive layer and the bottom and top contours of the adjacent layers are fed into the proposed algorithm in the form of the contour and normal vector to create curved-form sloping surfaces. Following curved-form adaptive slicing, a customized machine path compatible with a five-axis abrasive waterjet (AWJ) machine will be generated for any user-defined sheet thicknesses.

Findings
– The implemented system yields curved-form adaptive slices for a variety of models with diverse types of surfaces (e.g. flat, convex, and concave), different slicing direction, and different number of sheets with different thicknesses. The decrease in layer thickness and increase of the number of the sloped cuts can make the prototype as close as needed to the CAD model.

Research limitations/implications
– The algorithm is designed for use with five-axis AWJ cutting of any kind of geometrical complex surfaces. Future research would deal with the nesting problem of the layers being spread on the predefined sheet as the input to the five-axis AWJ cutter machine to minimize the cutting waste.

Practical implications
– The algorithm generates adaptive layers with concave or convex curved-form surfaces that conform closely to the surface of original CAD model. This will pave the way for the accurate fabrication of metallic functional parts and tooling that are made by the attachment of one layer to another. Validation of the output has been tested only as the simulation model. The next step is the customization of the output for the physical tests on a variety of five-axis machines.

Originality/value
– This paper proposes a new close to CAD design sloped-edge adaptive slicing algorithm applicable to a variety of five-axis processes that allow variable thickness layering and slicing in different orientations (e.g. AWJ, laser, or plasma cutting). Slices can later be bonded to build fully solid prototypes.
State-of-the-art in empirical modelling of rapid prototyping processes
Authors: Garg A. , Tai K. , Savalani M.M. 
Published: March 2014

Purpose– The empirical modelling of major rapid prototyping (RP) processes such as fused deposition modelling (FDM), selective laser sintering (SLS) and stereolithography (SL) has attracted the attention of researchers in view of their contribution to the overall cost of the product. Empirical modelling techniques such as artificial neural network (ANN) and regression analysis have been paid considerable attention. In this paper, a powerful modelling technique using genetic programming (GP) for modelling the FDM process is introduced and the issues related to the empirical modelling of RP processes are discussed. The present work aims to investigate the performance of various potential empirical modelling techniques so that the choice of an appropriate modelling technique for a given RP process can be made. The paper aims to discuss these issues.Design/methodology/approach– Apart from the study of applications of empirical modelling techniques on RP processes, a multigene GP is applied to predict the compressive strength of a FDM part based on five given input process parameters. The parameter setting for GP is determined using trial and experimental runs. The performance of the GP model is compared to those of neural networks and regression analysis.Findings– The GP approach provides a model in the form of a mathematical equation reflecting the relationship between the compressive strength and five given input parameters. The performance of ANN is found to be better than those of GP and regression, showing the effectiveness of ANN in predicting the performance characteristics of the FDM part. The GP is able to identify the significant input parameters that comply with those of an earlier study. The distinct advantages of GP as compared to ANN and regression are highlighted. Several vital issues related to the empirical modelling of RP processes are also highlighted in the end.Originality/value– For the first time, a review of the application of empirical modelling techniques on RP processes is undertaken and a new GP method for modelling the FDM process is introduced. The performance of potential empirical modelling techniques for modelling RP processes is evaluated. This is an important step in modernising the era of empirical modelling of RP processes.

The father's roles in the recovery of youngChinese suffering from anorexia nervosa in twoChinese cities,HongKong andShenzhen
Authors: Ma Joyce L. C. 
Published: March 2014

The fathers' role in assisting the recovery of youngChinese diagnosed with anorexia nervosa has seldom been documented inChinese contexts, namelyHongKong and Shenzhen. In this article the author argues for the importance of engaging the absentChinese father in helping in this context, describing the process of family treatment and highlighting the treatment principles and skills in achieving the goal of helping, illustrating it with two clinical cases from twoChinese cities,HongKong andShenzhen.Practitioner pointsEngaging the absent father in treatment to join hands with his spouse is crucial to assist a youngChinese person with anorexia nervosa to recover.Translation of the young person's symptoms as a developmental challenge is clinically useful to achieve the goal of paternal engagement.Increased paternal involvement to mediate mother–daughter conflicts, raising the father's self‐confidence and improved marital relationships are clinically useful

Published: March 2014

BackgroundPregnancy after perinatal death is characterised by elevated stress and anxiety, increasing the risk of adverse short‐term and long‐term outcomes.ObjectivesThis metasynthesis aimed to improve understanding of parents’ experiences of maternity care in pregnancy after stillbirth or neonatal death.Search strategySix electronic databases were searched using predefined search terms.Selection criteriaEnglish language studies using qualitative methods to explore the experiences of parents in pregnancy after perinatal loss, were included subject to quality appraisal framework.Data collection and analysisSearches were initiated in December 2011 and finalised in March 2013. Studies were synthesised using an interpretive approach derived from meta‐ethnography.Main resultsFourteen studies were included in the synthesis, graded A (no or few flaws, high trustworthiness; n = 5), B (some flaws, unlikely to affect trustworthiness; n = 5) and C (some flaws, possible impact on trustworthiness; n = 4). Three main themes were identified; co‐existence of emotions, helpful and unhelpful coping activities and seeking reasssurance through interactions.ConclusionParents’ experiences of pregnancy are profoundly altered by previous perinatal death; conflicted emotions, extreme anxiety, isolation and a lack of trust in a good outcome are commonly reported. Emotional and psychological support improves parents’ experiences of subsequent pregnancy, but the absence of an evidence base may limit consistent delivery of optimal care within current services.

Published: March 2014

AbstractDrinkable yogurt is a popular beverage in the United States and there may be a niche for carbonated drinkable yogurt in the functional foods market. Pomegranate (P) and vanilla (V) yogurt beverages were formulated, containing inulin as a prebiotic, along with probiotic bacteria Lactobacillus acidophilus and Bifidobacterium, to produce symbiotic products. These beverages were stabilized with high‐methoxyl pectin and whey protein concentrate and compared to samples with approximately 2 volumes of added carbon dioxide (CO2). Samples were stored in sealed glass bottles at 4 °C for 9 wk for evaluation of physicochemical and functional properties. Trials were carried out in triplicate and 3 replicates from each trial were analyzed. Physicochemical attributes were analyzed using standard AOAC methods. Survivability of the probiotics and changes in pH and viscosity were measured weekly. Chemical composition of the carbonated beverages was: protein: 1.58 ± 0.05%, 1.59 ± 0.06%, fat: 1.24 ± 0.2%, 1.18 ± 0.11%, total solids: 14.78 ± 0.11%, 14.93 ± 0.05%, ash: 0.49 ± 0.02%, 0.46 ± 0.03%, and carbohydrate (by difference): 11.47 ± 0.12%, 11.69 ± 0.14% for P and V, respectively. Both L. acidophilus and Bifidobacterium were stable and remained above 106 CFU/g for both flavors of beverage both with and without carbonation. The new manufacturing technology for these prototypes may have potential for commercialization of carbonated symbiotic milk‐based beverages.

ObjectiveThe purpose of this study was to determine the most clinically relevant baseline predictors of time‐to‐recovery from borderline personality disorder.MethodTwo hundred and ninety in‐patients meeting rigorous criteria for borderline personality disorder were assessed during their index admission using a series of semistructured interviews and self‐report measures. Recovery status, which was defined as concurrent symptomatic remission and good social and full‐time vocational functioning, was reassessed at eight contiguous 2‐year time periods. Survival analytic methods (Cox regression), which controlled for overall baseline severity, were used to estimate hazard ratios and their confidence intervals.ResultsAll told, 60% of the borderline patients studied achieved a 2‐year recovery. In bivariate analyses, seventeen variables were found to be significant predictors of earlier time‐to‐recovery. Six of these predictors remained significant in multivariate analyses: no prior psychiatric hospitalizations, higher IQ, good full‐time vocational record in 2 years prior to index admission, absence of an anxious cluster personality disorder, high extraversion, and high agreeableness.ConclusionTaken together, the results of this study suggest that prediction of time‐to‐recovery for borderline patients is multifactorial in nature, involving factors related to lack of chronicity, competence, and more adaptive aspects of temperament.

Published: March 2014

BackgroundFragmented QRS complex (fQRS) is associated with worse outcomes in several cardiovascular conditions. However, alterations in fQRS in patients with ST elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) and association of fQRS with myocardial blush grade (MBG) has not been investigated until now. In this study, we aimed to investigate the association of MBG after primary PCI with evolution of fQRS.MethodsOur study consisted of 401 consecutive patients with STEMI who underwent primary PCI. Patients were categorized into two subgroups according to persistence or new‐onset of fQRS (Group 1) and absence or resolution of fQRS (Group 2) at 48 hours after primary PCI. The evolution of fQRS on pre‐ and post‐PCI ECG and their relation with myocardial reperfusion parameters were investigated.ResultsPatients in group 1 showed older age, higher rate of smoking, lower HDL‐cholesterol, lower LVEF, higher angina‐to‐door time, higher TIMI frame count, and high rate of patients with MBG <3 compared to patients with group 2 (P < 0.05). In correlation analysis, LVEF showed positive correlation with MBG (r = 0.448, P < 0.001) and negative correlation with the number of leads with fQRS (r = –0.335, P < 0.001). In multivariate regression analysis, new‐onset or persistance of fQRS after primary PCI is significantly associated with MBG <3, peak CK‐MB level, pre‐PCI fQRS at anterior localization and smoking.ConclusionOur findings showed that despite complete ST‐segment resolution in all patients, fQRS is independently associated with impaired microvascular myocardial perfusion. So, fQRS, as a simple and easily available noninvasive marker, may be useful in stratification of high‐risk patients with increased extent of infarcted myocardium who underwent primary PCI.

Published: March 2014

BackgroundWe aimed to evaluate whether heart rate variability (HRV) could predict prolonged asystole before head‐up tilt table test (HUTT) by comparing time domain HRV parameters of patients with type 2B vasovagal syncope (VVS) and patients with other types of VVS.MethodsNinety‐eight patients who examined with 24‐hour Holter electrocardiogram monitoring before HUTT and diagnosed with VVS were enrolled. Patients were divided into two groups in accordance with their VVS type as group 1 (n = 43) consisting of patients with type 2B VVS and group 2 (n = 57) consisting of patients with other types of VVS. Time domain HRV parameters (SDNN, SDANN, SDNN index, RMSSD, pNN50) of two groups were compared. ROC curve analysis was performed to predict best cutoff values that could prognosticate occurrence of prolonged asystole during HUTT.ResultsSDNN, SDANN, SDNN index values were significantly longer for group 1 compared to group 2 (P = 0.009, P = 0.006, P = 0.004; respectively). While a SDNN cutoff value of ≥151 ms predicted occurrence of type 2B VVS before HUTT with 69% sensitivity and 56% specificity, a SDANN value of ≥164 ms had 47% sensitivity and 87% specificity and a SDNN index value of ≥102 ms showed 40% sensitivity and 85% specificity.ConclusionsIn our study, we tried to demonstrate prediction of prolonged asystole by analyzing HRV parameters before HUTT. We found out that time domain HRV parameters were longer in patients with type 2B VVS than patients with other types of VVS. Our results need to be supported by extensive studies.
TERT promoter mutation is uncommon in acral lentiginous melanoma

Published: March 2014

BackgroundMelanoma is a heterogeneous group of diseases with distinct sets of genetic changes. Recurrent and mutually exclusive C>T or CC>TT transition mutations were identified in the promoter region of the reverse transcriptase catalytic subunit of the telomerase gene (TERT) in melanoma recently, and it was suggested that they enhanced the expression of TERT gene and played important roles in the melanoma pathogenesis. These mono or di‐nucleotide transitions were ultraviolet (UV)‐signature mutations.MethodsIn this study, polymerase chain reaction and direct sequencing of TERT promoter using formalin‐fixed and paraffin‐embedded tissue was performed to investigate whether these UV‐signature mutations were also present in acral lentiginous melanoma.ResultsTERT promoter mutation was identified in only 2 of the 32 cases (6%) of acral lentiginous melanomas while it was identified in 3 of the 9 cases (33%) of non‐acral cutaneous melanomas. The difference was statistically significant (p = 0.028).ConclusionsThe rarity of TERT promoter mutation in the acral lentiginous melanoma was consistent with the supposed role of UV light in the melanoma pathogenesis and also corroborated the view that acral lentiginous melanomas have a different pathogenesis with the melanomas from sun‐exposed sites.
Restrictions in pub closing times and lockouts in Newcastle, Australia five years on
Authors: Kypri Kypros , McElduff Patrick , Miller Peter 
Published: March 2014

AbstractIntroduction and Aims.In 2008 pub closing times were restricted from 5am to 3:30am in the central business district (CBD) of Newcastle, Australia. A previous study showed a one‐third reduction in assaults in the 18 months following the restriction. We assessed whether the assault rate remained lower over the following 3.5 years and whether the introduction of a ‘lockout’ in nearby Hamilton was associated with a reduction in assaults there.Design and Methods.We used a pre‐post design with comparison against two post‐change periods. The setting was Greater Newcastle (population 530 000) and subjects were persons apprehended for assault in the CBD and nearby Hamilton, an area with late trading pubs where a lockout and other strategies were implemented in 2010. Cases were police‐recorded assault apprehensions occurring from 10pm to 6am in one pre‐change period: January 2001 to March 2008, and two post‐change periods: (i) April 2008 to September 2009 and (ii) October 2009 to March 2013. Negative binomial regression with terms for secular trend and seasonal effects was used to estimate Post1: Pre and Post2: Pre Incidence Rate Ratios and confidence intervals.Results.In the CBD recorded assaults fell from 99/quarter before the restriction to 68/quarter in the first post‐change period [incidence rate ratio (IRR) 0.67, 95% confidence interval (CI) 0.55–0.82] and 71/quarter (IRR: 0.68, 95% CI: 0.55‐0.85) in the later post‐change period. In the same periods in Hamilton, assault rates were 23, 24, and 22 per quarter respectively.Discussion and Conclusions.The restriction in closing time was associated with a sustained lower assault rate in the Newcastle CBD. We find no evidence that lockouts and other outlet management strategies were effective in Hamilton. [Kypri K, McElduff P, Miller P.
