Usability testing for an open-source integrated library system
Authors: Khatun Asma , Ahmed S.M. Zabed 
Published: May 2018

Purpose
The aim of this paper is to empirically examine the usability of the Koha OPAC from a user perspective.

Design/methodology/approach
A series of usability tests with Koha were carried out at a private university in Bangladesh. Both experienced and novice users participated in these tests. Experienced users participated only once, whereas novices took part in three successive sessions. At first, novices’ initial performance was recorded. Then, they performed the same tasks after a short training tutorial. Novices again participated in the retention experiment with the same tasks after four weeks. A set of seven tasks was given to the users to see their performance in terms of time taken, number of errors made and success scores. Performance data were captured through a computer screen recording software, and satisfaction scores were obtained using a modified version of Questionnaire on User Interface Satisfaction (QUIS). Comparisons of performance and satisfaction with Koha OPAC were made between experienced users and novices’ initial, learning and retention experiments and amongst novices’ three test sessions.

Findings
The results showed significant performance difference between experienced and novices’ initial session. Novices could easily pick up the functionality of Koha OPAC when a brief training was provided. The comparative analysis of performance between experienced users and novices’ learning showed no significant difference between these sessions. There was a significant difference between experienced and novices’ retention in terms of success scores. The comparison amongst novices’ initial, learning and retention sessions showed significant performance differences in time taken and errors made. The QUIS results also showed significant differences in subjective satisfaction for several items between experienced users and naïve sessions, and for one item amongst novices’ three experiments.

Originality/value
This is a pioneering study of the task-based usability of Koha OPAC. The findings from this study will encourage researchers to empirically examine the usability of other open-source ILSs, which might result in improved user performance and satisfaction with these systems.
The uncertainty mapping of ontologies based on three-dimensional combination weight vector space model
Authors: Han Dongmei , Wang Wen , Luo Suyuan , Fan Weiguo , Wang Songxin 
Published: May 2018

Purpose
This paper aims to apply vector space model (VSM)-PCR model to compute the similarity of Fault zone ontology semantics, which verified the feasibility and effectiveness of the application of VSM-PCR method in uncertainty mapping of ontologies.

Design/methodology/approach
The authors first define the concept of uncertainty ontology and then propose the method of ontology mapping. The proposed method fully considers the properties of ontology in measuring the similarity of concept. It expands the single VSM of concept meaning or instance set to the “meaning, properties, instance” three-dimensional VSM and uses membership degree or correlation to express the level of uncertainty.

Findings
It provides a relatively better accuracy which verified the feasibility and effectiveness of VSM-PCR method in treating the uncertainty mapping of ontology.

Research limitations/implications
The future work will focus on exploring the similarity measure and combinational methods in every dimension.

Originality/value
This paper presents an uncertain mapping method of ontology concept based on three-dimensional combination weighted VSM, namely, VSM-PCR. It expands the single VSM of concept meaning or instance set to the “meaning, properties, instance” three-dimensional VSM. The model uses membership degree or correlation which is used to express the degree of uncertainty; as a result, a three-dimensional VSM is obtained. The authors finally provide an example to verify the feasibility and effectiveness of VSM-PCR method in treating the uncertainty mapping of ontology.
Development of a surgical site infection surveillance programme in a Scottish neurosurgical unit
Authors: Canty Michael , George Edward Jerome St 
Published: May 2018

Purpose
Surgical site infection (SSI) is a common complication in surgical practice. SSIs represent almost a fifth of healthcare-associated infections in Scotland, and have deleterious effects on mortality, morbidity, length of stay, and cost to the health service. SSIs in neurosurgery may be more consequential than in other specialities given the potentially devastating effects of central nervous system infection. The paper aims to discuss these issues.

Design/methodology/approach
In 2014, the authors became concerned about an anecdotal increase in infection rates in the authors’ unit. While national guidance on SSI surveillance existed in England and Scotland, the authors had no relevant procedures or policies in Glasgow, and began the process of establishing a surveillance programme. This was driven by clinicians but faced challenges due to a lack of involvement of the wider organisation in the early stages.

Findings
SSIs were initially reported via a form-filling system. This developed into an editable hospital intranet database, but still suffered from the problems of voluntary entries and under-reporting. Following the formal engagement of management structures and the funding of a surveillance nurse, the authors’ programme developed robustness, and resilience. With the advent of an SSI committee, the authors now have a well-established programme that ingrains SSI prevention in the collective learning and organisational memory of the authors’ unit.

Originality/value
Clinicians must lead on the development of these programmes, but long-term durability requires engagement and support from the wider organisation.
Impact of federal income tax rates and government borrowing on nominal interest rate yields on tax-free municipal bonds
Authors: Cebula Richard , Nair-Reichert Usha 
Published: May 2018

PurposeThis study investigates the impact of federal income tax rates and budget deficits on the nominal interest rate yield on high-grade municipal tax-free bonds (municipals) in the US. The 58-year study period covers the years 1959 through 2016 and thus is very recent.Design/methodology/approachThe study develops a loanable funds model that allows for various financial market factors. Once developed, the model is estimated by autoregressive two-stage least squares, with a Newey-West heteroskedasticity correction.FindingsThe nominal interest rate yield on municipals is a decreasing function of the maximum marginal federal personal income tax rate and an increasing function of the federal budget deficit (expressed as a per cent of GDP). This yield is also an increasing function of nominal interest rate yields on three- and ten-year treasury notes and expected inflation.Research limitations/implicationsWhen introducing additional interest rates such as treasury bills as explanatory variables, multi-collinearity becomes a serious problem.Practical implicationsThis study indicates that lower maximum federal personal income tax rates and larger federal budget deficits, both act to raise borrowing costs for cities (of all sizes), counties and states across the country. Given the study period of 58 years, these relationships appear to be enduring ones that responsible policy-makers should not overlook.Social implicationsTax reform and debt management need to be conducted in a very circumspect fashion.Originality/valueNo recent study investigating the impact of the two key policy variables in this study has been published.
CCP recovery and resolution: preventing a financial catastrophe
Authors: Priem Randy 
Published: May 2018

Purpose
This paper aims to discuss the European Commission’s proposal for a central counterparty (CCP) recovery and resolution regulation. In this respect, the paper comments the consequences, risks and attention points for CCPs and their authorities.

Design/methodology/approach
This paper focuses on the proposed rules surrounding CCP recovery and resolution. The paper first familiarizes the reader with the risk management procedures currently obliged before discussing the resolution and recovery provisions foreseen in the proposal.

Findings
The proposed regulation commands significant requirements for CCPs and for their regulators. Not only will CCPs have to draft a recovery plan but also a resolution authority will need to be assigned. The latter will have the task, in consultation with a resolution college, to draft a resolution plan. When a resolution is inevitable, authorities will need to assure the continuation of the CCP’s critical functions, thereby warranting financial stability and investor protection.

Originality/value
To the best of the author’s knowledge, there are no other papers that provide a holistic overview of the newly proposed regulation and describe the choices to be made during a CCP’s resolution. This paper will be of interest to all CCPs and their stakeholders, such as their regulators, clearing members and their clients and other linked financial market infrastructures.
The determinants of anti-money laundering compliance among the Financial Action Task Force (FATF) member states
Authors: Mekpor Emmanuel Senanu , Aboagye Anthony , Welbeck Jonathan 
Published: May 2018

PurposeThis paper aims to compute a measure for anti-money laundering/counter-financing of terrorism (AML/CFT) compliance and investigate its determinants.Design/methodology/approachUsing the Financial Action Task Force (FATF) recommendations and assigning weights to them, the study computes a measure for AML compliance. Further, the determinants of AML compliance were investigated using ordinary least squares (OLS) data of 155 countries between 2004 and 2016.FindingsThe findings suggest that AML compliance have slightly improved over the years. Further, the OLS regression results show that technology, regulatory quality, bank concentration, trade openness and financial intelligence center significantly determined and improved AML compliance.Practical implicationsFrom the findings, it is evident that countries that wish to improve the AML compliance should focus more on technology, regulatory quality, structure of the banking sector, size of the economy and institution of financial intelligence center so as to enhance AML compliance.Originality/valueTo the best of the author’s knowledge, this paper reveals a first AML/CFT compliance index that measures the cross-country level of AML/CFT compliance from the year 2004 to 2016. Subsequently, this paper adopted an OLS econometric model to identify the key determinants of AML/CFT compliance among member states of FATF.
Toward a socio-contextual understanding of transliteracy
Authors: Hovious Amanda 
Published: May 2018

Purpose
The purpose of this paper is to explore the emerging concept of transliteracy from the perspective of literacy as a socially constructed and contextual practice.

Design/methodology/approach
A systematic review of the literature explores the origins and development of transliteracy in the context of the multiple understandings of literacy. An argument is made that the current discussion among academic librarians about transliteracy as a set of skills is incompatible with its socio-constructivist roots.

Findings
Librarians’ interest in transliteracy stems from its relationship to information literacy, with current discussion focused on defining its skills. However, a skills-based perspective does not reflect the nature of what it means to be transliterate. Rather than a common set of skills that are practiced across multiple media platforms, transliteracy can be reconceptualized as a social practice that crosses multiple contexts (e.g. school, home and workplace).

Practical implications
This expanded understanding better aligns transliteracy to recent developments in information literacy, such as the knowledge practices of the ACRL framework.

Originality/value
This paper introduces an expanded understanding of transliteracy, adding to the growing conversation about the relationship between emergent literacies and information literacy.

Published: May 2018

ObjectiveTo develop a conceptual framework and preliminary item bank for childbirth‐specific patient‐reported outcome (PRO) domains.Data SourcesWomen, who were U.S. residents, ≥18 years old, and ≥20 weeks pregnant, were surveyed regarding their childbirth values and preferences (V&P) using online panels.Study DesignUsing community‐based research techniques and Patient‐Reported Outcomes Management Information System (PROMIS®) methodology, we conducted a comprehensive literature review to identify self‐reported survey items regarding patient‐reported V&P and childbirth experiences and outcomes (PROs). The V&P/PRO domains were validated by focus groups. We conducted a cross‐sectional observational study and fitted a multivariable logistic regression model to each V&P item to describe “who” wanted each item.Principal FindingsWe identified 5,880 V&P/PRO items that mapped to 19 domains and 58 subdomains. We present results for the 2,250 survey respondents who anticipated a vaginal delivery in a hospital. Wide variation existed regarding each V&P item, and personal characteristics, such as maternal confidence and ability to cope well with pain, were frequent predictors in the models. The resulting preliminary item bank consisted of 60 key personal characteristics and 63 V&P/PROs.ConclusionsThe conceptual framework and preliminary (PROMIS®) item bank presented here provide a foundation for the development of childbirth‐specific V&P/PROs.
Visibility of bony structures around hip prostheses in dual‐energy CT: With or without metal artefact reduction software

Published: May 2018

AbstractIntroductionThe development of dual‐energy CT and metal artefact reduction software provides a further chance of reducing metal‐related artefacts. However, there have been only a few studies regarding whether MARs practically affect visibility of structures around a metallic hip prosthesis on post‐operative CT evaluation.MethodsTwenty‐seven patients with 42 metallic hip prostheses underwent DECT. The datasets were reconstructed with 70, 90 and 110 keV with and without MARs. The areas were classified into 10 zones according to the reference zone. All the images were reviewed in terms of the severity of the beam‐hardening artefacts, differentiation of the bony cortex and trabeculae and visualization of trabecular patterns with a three‐point scale. The metallic screw diameter was measured in the acetabulum with 110 keV images.ResultsThe scores were the worst on 70 keV images without MARs [mean scores:1.84–4.22 (p < 0.001–1.000)]. The structures in zone II were best visualized on 110 keV (p < 0.001–0.011, mean scores: 2.86–5.22). In other zones, there is general similarity in mean scores whether applying MARs or not (p < 0.001–0.920). The mean diameter of the screw was 5.85 mm without MARs and 3.44 mm with MARs (mean reference diameter: 6.48 mm).ConclusionThe 110 keV images without MARs are best for evaluating acetabular zone II. The visibility of the bony structures around the hip prosthesis is similar in the other zones with or without MARs regardless of keV. MARS may not be needed for the evaluation of the metallic hip prosthesis itself at sufficient high‐energy levels; however, MARS still has a role in the evaluation of other soft tissues around the prosthesis.
Upper airway obstruction assessment: Peak inspiratory flow and clinical COPD Questionnaire
Authors: Sanchez‐Guerrero J. , Guerlain J. , Samaha S. , Burgess A. , Lacau St Guily J. , Périé S. 
Published: May 2018

ObjectivesSpirometric evaluation of upper airway obstruction (UAO) is not commonly performed by Otolaryngologists. In addition, functional evaluation of UAO by flow‐volume loops (FVL) is not available in all clinical settings. More recently, peak inspiratory flow (PIF) has proven to be a useful tool to monitor UAO at the patient's bedside. The aim of this work is to assess the role of PIF measured with a simple flow metre (In‐Check method) as a standardised, simple, non‐invasive tool in quantifying chronic and subacute UAO in a routine clinical practice. In addition, a Clinical COPD Questionnaire (CCQ), previously validated to assess the psychophysical status in patients with laryngotracheal stenosis, was utilised to evaluate respiratory function in UAO.DesignProspective cohort study.SettingsUniversity teaching hospital.ParticipantsSeventy 2 subjects, an UAO group of 26 patients and a control group of 46 healthy subjects.Main outcome measuresThe ability of PIF values to discriminate between the UAO group and the control group was assessed using a ROC curve. A Spearman rank correlation was used to test the relationship between PIF measurements and the global CCQ score. Additionally, an analysis of CCQ at domain and items levels was performed.ResultsPeak inspiratory flow values were accurate, with an area under the ROC curve (AUC) of 0.98 (P < .05) for differentiating the control group from the UAO group. A threshold PIF value of 170 L/min was found for diagnosing UAO. An inconclusive negative trend was found (r = −.19; P = .35) between PIF values and CCQ global score. Concerning CCQ, the symptoms domain was the most affected by UAO, higher than mental domains (P < .001) as well as functional domains (P < .01). Exertional dyspnoea and cough were the items that obtained the highest disturbed scores.ConclusionsPeak inspiratory flow is a non‐invasive, quantitative parameter to evaluate the severity of UAO. Testing can be easily performed in a routine clinical setting, with a non‐expensive hand‐held device, and could help medical follow‐up programmes and prevent emergency situations. However, FVL may be necessary for further assessment of UAO diseases. The CCQ confirms that exertional dyspnoea is the main symptom of UAO, but cough remains a common symptom.

BackgroundLeft ventricular hypertrophy (LVH) may reflect a wide variety of physiologic and pathologic conditions. Thus, it can be misleading to consider all LVH to be homogenous or similar. Refined 4‐group classification of LVH based on ventricular concentricity and dilatation may be identified. To determine whether the 4‐group classification of LVH identified distinct phenotypes, we compared their association with various noninvasive markers of cardiac stress.MethodsCohort of unselected adult outpatients referred to a seven tertiary care echocardiographic laboratory for any indication in a 2‐week period. We evaluated the LV geometric patterns using validated echocardiographic indexation methods and partition values.ResultsStandard echocardiography was performed in 1137 consecutive subjects, and LVH was found in 42%. The newly proposed 4‐group classification of LVH was applicable in 88% of patients. The most common pattern resulted in concentric LVH (19%). The worst functional and hemodynamic profile was associated with eccentric LVH and those with mixed LVH had a higher prevalence of reduced EF than those with concentric LVH (P < .001 for all).ConclusionsThe new 4‐group classification of LVH system showed distinct differences in cardiac function and noninvasive hemodynamics allowing clinicians to distinguish different LV hemodynamic stress adaptations in patients with LVH.
Cholinergic modulation of striatal microcircuits
Authors: Abudukeyoumu Nilupaer , Hernandez‐Flores Teresa , Garcia‐Munoz Marianela , Arbuthnott Gordon W. 
Published: May 2018

AbstractThe purpose of this review is to bridge the gap between earlier literature on striatal cholinergic interneurons and mechanisms of microcircuit interaction demonstrated with the use of newly available tools. It is well known that the main source of the high level of acetylcholine in the striatum, compared to other brain regions, is the cholinergic interneurons. These interneurons provide an extensive local innervation that suggests they may be a key modulator of striatal microcircuits. Supporting this idea requires the consideration of functional properties of these interneurons, their influence on medium spiny neurons, other interneurons, and interactions with other synaptic regulators. Here, we underline the effects of intrastriatal and extrastriatal afferents onto cholinergic interneurons and discuss the activation of pre‐ and postsynaptic muscarinic and nicotinic receptors that participate in the modulation of intrastriatal neuronal interactions. We further address recent findings about corelease of other transmitters in cholinergic interneurons and actions of these interneurons in striosome and matrix compartments. In addition, we summarize recent evidence on acetylcholine‐mediated striatal synaptic plasticity and propose roles for cholinergic interneurons in normal striatal physiology. A short examination of their role in neurological disorders such as Parkinson's, Huntington's, and Tourette's pathologies and dystonia is also included.
Trade and organization in the colonial Caribbean
Authors: Finucane Adrian 
Published: May 2018

AbstractTrade created connections, whether officially sanctioned or illicit, within the Caribbean. Yet traditional approaches to the history of the early modern Caribbean have often considered only the Spanish, French, or English empires or formal contact among colonies, neglecting the constructive power of networks of interaction among merchants, sailors, and even pirates. These contacts drew the islands and shores into a cohesive region that owed its existence more to regional exchange than to the metropoles of Europe that wished to control particular geographies. By looking at smuggling and the actions of empires such as the Dutch and Portuguese, whose approaches to trade differed greatly from those of imperial powers that controlled larger amounts of land, recent historical work on the colonial Caribbean has revealed the importance of legal and contraband trade in creating an entangled region with linked economies, suggesting the limits of approaching the Caribbean from the perspective of any one single empire.
