Through three lenses: transfer students and the library
Authors: Sandelli Anna 
Published: June 2017

PurposeThe aim of this paper is to examine literature related to transfer students and students in transition through three interrelated lenses: student demographics and experiences, considerations encountered by institutions of higher education working to support these students and academic libraries’ interactions with this growing population.Design/methodology/approachLibrary and information science and education databases were searched for articles related to transfer student experiences and initiatives. Educational research and policy centers were also investigated for supplemental data and definitions.FindingsSeveral key considerations for academic libraries interested in supporting transfer students emerged, including the growth and diversity of this population; academic, social and procedural experiences encountered during and after students’ transition; commonalities and differences with native first-year students; and the value of partnerships in fostering student success.Practical implicationsThis review contextualizes conversations regarding transfer student experiences, providing a resource for librarians to understand this population from multiple perspectives and to use these perspectives to develop and enhance initiatives, resources and services.Originality/valueDespite an increased emphasis on transfer students across higher education, there is little literature regarding libraries’ involvement with this population. This literature review also seeks to expand upon existing conversations by examining transfer student experiences beyond the library that could inform both their interactions with the library and the ways in which libraries connect and communicate with these students.
Tacit knowledge sharing among library colleagues: a pilot study
Authors: Burnette Margaret 
Published: June 2017

PurposeThis study aims to explore the nature of tacit knowledge (TK) sharing among library colleagues, with a focus on the characteristics of TK and contextual factors such as organizational culture or the mentor/mentee relationship.Design/methodology/approachUsing a critical incident approach, participants self-selected based on pre-established criteria to report knowledge sharing incidents between colleagues at either an in-person or virtual reference desk. Subsequent semi-structured interviews were transcribed from recordings and coded for thematic elements.FindingsThree thematic areas emerged. First are the influence of organizational culture and the importance of trust on knowledge sharing behavior. Second, the value of teamwork and the significance of mentor/mentee roles surface as significant drivers of TK exchange. Last but not least is a better understanding of the nature of TK, as it relates to types of knowledge and characterizations of experience and expertise.Research limitations/implicationsThe relatively small sample size nevertheless revealed some important findings that contribute to the understanding of the role of TK sharing in libraries.Originality/valueThe value of knowledge sharing in libraries is not well understood. This study demonstrates the value on several levels, including the influence of culture and trust, and the power of mentoring to harness TK held by experts. The proposed Tacit Knowledge Alignment Framework contributes to the understanding of the nature of TK in libraries. These findings begin to fill a research gap by furthering our understanding of TK and informing future retention efforts that are lacking in many libraries.
Statistical and judgmental criteria for scale purification
Authors: Wieland Andreas , Durach Christian F. , Kembro Joakim , Treiblmaier Horst 
Published: June 2017

Purpose
“Scale purification” – the process of eliminating items from multi-item scales – is widespread in empirical research, but studies that critically examine the implications of this process are scarce. The goals of this research are threefold: to discuss the methodological underpinning of scale purification, to critically analyze the current state of scale purification in supply chain management (SCM) research and to provide suggestions for advancing the scale-purification process.

Design/methodology/approach
A framework for making scale-purification decisions is developed and used to analyze and critically reflect on the application of scale purification in leading SCM journals.

Findings
This research highlights the need for rigorous scale-purification decisions based on both statistical and judgmental criteria. By applying the proposed framework to the SCM discipline, a lack of methodological rigor and coherence is identified when it comes to current purification practices in empirical SCM research. Suggestions for methodological improvements are provided.

Research limitations/implications
The framework and additional suggestions will help to advance the knowledge about scale purification.

Originality/value
This paper demonstrates that the justification for scale purification needs to be driven by reliability, validity and parsimony considerations, and that this justification needs to be based on both statistical and judgmental criteria.
Conservation benefits of international Aichi protection and restoration targets for future epiphyte metapopulations

Published: June 2017

Abstract

More than half way towards the deadline for 2020 Aichi targets, a key question is whether the metapopulation dynamics of dispersal‐restricted habitat specialists can be sustained under current international targets of protection and restoration.

We present the first metapopulation projections under scenarios of multiple Aichi biodiversity targets of protecting high‐quality habitats and restoring suboptimal quality habitats under management. We simulate 200 years of metapopulation dynamics of nine old‐growth beech (Fagus sylvatica)‐associated epiphytic lichens, under a range of protection and restoration scenarios in a realistic landscape realm.

Protection was generally more efficient than restoration, where protection resulted in a constant increase in occupancy over time. However, projections showed that substantial increments in the number of occupied protected beech stands will most likely occur within the next 100–200 years. The time frame was dependent on species‐specific dispersal restriction, occupancy levels at onset and forest‐age requirements. Suboptimally restored beech stands increased lichen metapopulation sizes over a transient period and shortened the time for dispersal‐restricted species to reach higher occupancy levels inside protected areas of the landscape (c. 85–125 years).

Synthesis and applications. Based on projections of metapopulation dynamics of species associated with old‐growth forest, we argue that a combination of protection and restoration with the shortest possible time frame for increasing occupancy is the safest strategy. This is especially important under climatic and socio‐political changes that are unforeseeable over centuries. If choosing between conservation strategies, highest priority should be given to increased protection because it means larger metapopulation sizes of these species on the long term.

Published: June 2017

SummaryMuscle loss and arterial stiffness share common risk factors and are commonly seen in the elderly. We aimed to synthesise the existing literature on studies that have examined this association. We searched electronic databases for studies reporting correlations or associations between a measure of muscle tissue and a measure of arterial stiffness. Meta‐analysis was conducted using Fisher's Z‐transformed r‐correlation (rZ) values. Pooled weighted rZ and 95% confidence intervals were calculated in an inverse‐variance, random‐effects model. Heterogeneity was assessed by the inconsistency index (I2). Study quality was assessed on a checklist using items from validated quality appraisal guidelines. 1195 records identified, 21 satisfied our inclusion criteria totalling 8558 participants with mean age 52±4 years (range 23‐74). Most studies reported an inverse relationship between muscle tissue and arterial stiffness. Eight studies had data eligible for meta‐analysis. Muscle tissue was inversely associated with pulse wave velocity in healthy individuals [rZ=−.15 (95% CI −0.24, −0.07); P=.0006; I2=85%; n=3577] and in any population [rZ=−.18 (−0.26, −0.10); P<.0001; I2=81%; n=3930]. In a leave‐one‐out sensitivity analysis, the results remained unchanged. Lower muscle tissue was associated with arterial stiffness. Studies were limited by cross‐sectional design. Cardiovascular risk monitoring may be strengthened by screening for low muscle mass and maintaining muscle mass may be a primary prevention strategy.

AbstractGender disparities in resource access, utilization and competitiveness in agricultural production have been critical challenges to the achievement of food security and inclusive growth in Africa. Thus, this article determined rice farmers’ productivities and competitiveness, their willingness to undertake and factors influencing their participation in agribusiness across gender, using descriptive and inferential statistics. The study employed a case study of rice farmers in Ibaji Local Government Area of Kogi State, Nigeria, to reach its conclusion. The study concluded that in spite of the willingness to invest in agribusiness, gender imbalance in socioeconomic status, resource use and incomes were still recurring issues limiting productivity, competiveness in rice production and by extension, food security. To feed Africa, there is the need to close the gender gap in socio‐economic status, resource access, productivity and competitiveness, align national with regional agenda and the global sustainable development goals on hunger and equity, with the view to pooling resources towards tackling the food insecurity on an equitable and sustainable basis. It has also become imperative to support effective policy deployment, implement proven innovative and sustainable agri‐business models and embark on targeted gender support within country and regional settings.

Published: June 2017

AbstractTwo endemic subterranean freshwater amphipod species have been discovered in groundwater of the volcanic active zone in Iceland, Crangonyx islandicus and Crymostygius thingvallensis. At least five different ciliate sequences were isolated from C. islandicus and the analysis of variation at the 18S ribosomal DNA gene suggests that they present previously unsequenced species, from the orders Apostomatida and Philasterida. Apostome ciliates are well known to be exuviotrophic epibionts on crustaceans. Analyses of ciliate epibionts from different groundwater amphipod species from North America and mainland Europe revealed distinct groups of ciliates and higher diversity on the epigean amphipod Crangonyx pseudogracilis. Analysis of geographic patterns of the most common ciliate within Iceland revealed population differentiation supporting limited current connectivity between the different groundwater systems. Our study reports an occurrence of previously undescribed ciliate species in a groundwater ecosystem characterized by low species diversity.

SummaryBackgroundAsthma and chronic obstructive pulmonary disease (COPD) are heterogeneous diseases. The phenotypes that have clinical features of both asthma and COPD are still incompletely understood.ObjectiveTo clarify the best discriminators of the asthma‐COPD overlap phenotype from asthma and COPD subgroups using a clustering approach.MethodsThis study assessed pathophysiological parameters, including mRNA expression levels of T helper cell‐related transcription factors, namely TBX21 (Th1), GATA3 (Th2), RORC (Th17) and FOXP3 (Treg), in peripheral blood mononuclear cells in asthma patients (n=152) and in COPD patients (n=50). Clusters were determined using k‐means clustering. Exacerbations of asthma and COPD were recorded during the 1‐year follow‐up period.ResultsThe cluster analysis revealed four biological clusters: cluster 1, predominantly patients with COPD; cluster 2, patients with an asthma‐COPD overlap phenotype; cluster 3, patients with non‐atopic and late‐onset asthma; and cluster 4, patients with early‐onset atopic asthma. Hazard ratios for exacerbation were 2.5 (95% confidence interval [CI], 1.1‐5.6) in cluster 1 and 2.3 (95% CI, 1.0‐5.0) in cluster 2 compared with patients in other clusters. Cluster 2 was discriminated from other clusters by total serum IgE level ≥310 IU/mL, blood eosinophil counts ≥280 cells/μL, a higher ratio of TBX21/GATA3, FEV1/FVC ratio <0.67 and smoking ≥10 pack‐years with an area under the curve of 0.94 (95% CI, 0.90‐0.98) in the receiver operating characteristic analysis.Conclusions and Clinical RelevanceThe asthma‐COPD overlap phenotype was characterized by peripheral blood eosinophilia and higher levels of IgE despite the Th2‐low endotype.

Published: June 2017

SummaryObjectiveAutonomous cortisol secretion of adrenal incidentalomas (AIs) is associated with poor cardiovascular outcome. Because centripetal obesity is a cardiovascular risk factor, we aimed to investigate whether autonomous cortisol secretion is associated with increased visceral fat accumulation.DesignRetrospective cohort study.PatientsPatients with AIs who attended for follow‐up between January 2014 and December 2016 were evaluated. Autonomous cortisol secretion was diagnosed when 1 mg overnight dexamethasone (post‐DST) cortisol was >50 nmol/L at baseline and follow‐up. Follow‐up duration was 34 (12‐105) months. Thirty patients with nonfunctioning AIs and 44 patients with autonomous cortisol secretion were included. Adrenalectomy was performed in five patients. Six patients with Cushing's syndrome were also recruited.MeasurementsHormonal evaluation and assessment of total (T), visceral (V) and subcutaneous (S) fat area by computed tomography and calculation of V:S and V:T ratios at baseline and follow‐up.ResultsV, V:S and V:T increased (P<.001 for each comparison, Wilcoxon signed rank test for repeated measures) in patients with autonomous cortisol secretion while did not change significantly in patients with nonfunctioning adenomas. Linear regression models including post‐DST cortisol, gender, concomitant treatments and follow‐up duration showed that both baseline and follow‐up DST significantly predicted Δ(V:S) and Δ(V:T) (P<.01 for all models).ConclusionsIn patients with AIs, a post‐DST cortisol >50 nmol/L at both baseline and follow‐up, was associated with a significant increase in visceral fat after a follow‐up duration of ~3 years. This may be of importance to explain the link between autonomous cortisol secretion and poor cardiovascular outcome.

Published: June 2017

AimGrowth charts for cerebral palsy (CP) have been constructed using data for 24 920 Californian patients, covering ages 2 to 20 years, with separate charts for the five severity levels of the Gross Motor Function Classification System (GMFCS). Our aim was to test how the data for British children with CP fit these charts, compared with conventional local charts.MethodUS CP growth reference was reanalysed using the lambda‐mu‐sigma (LMS) method to allow calculation of standard deviation z‐scores. Growth data for 195 children with CP in Glasgow, UK, were retrieved and converted to z‐scores using the CP reference as well as the combined World Health Organization and UK 1990 growth reference (UK‐WHO).ResultsCompared to the UK‐WHO reference, measurements diverged progressively with increasing severity, with mean height for GMFCS level V being close to the second UK‐WHO centile. Compared with the CP reference, mean height and weight z‐scores were between the 50th and 75th centiles for all severity levels, while body mass index was just below the 50th centile.InterpretationBritish children with severe CP seem relatively very small when their growth data are plotted on non‐CP charts, but their data for weight and body mass index fit well to US CP charts and reasonably well for height. The LMS look‐up tables will make it possible to calculate z‐scores and produce charts in local formats.

AimsTo compare the efficacy and safety of dipeptidyl peptidase‐4 inhibitors (DPP‐4is) and sodium‐glucose cotransporter‐2 inhibitors (SGLT‐2is) as monotherapy or add‐on to metformin (Met) in patients with type 2 diabetes mellitus (T2DM).Materials and Methods
PubMed, Embase and ClinicalTrials.gov sites were systematically searched for randomized controlled trials to assess the efficacy and safety of DPP‐4is and SGLT‐2is in patients with T2DM. Risk ratio (RR) and weighted mean difference (WMD) were used to evaluate outcomes.ResultsIn the analysis of 25 randomized trials, which involved 14 619 patients, SGLT‐2is were associated with a significantly stronger reduction in haemoglobin A1c (HbA1c) (WMD 0.13%, 95% credible interval [CI], 0.04%‐0.22%, P = .005) and fasting plasma glucose (FPG) (WMD 0.80 mmol/L, 95% CI, 0.58‐1.01 mmol/L, P < .00001) than were DPP‐4is. However, no significant difference between the 2 drug categories was found in the risk of hypoglycaemic events (RR, 0.99; 95% CI, 0.78‐1.26, P = .92). SGLT‐2is plus Met was associated with a more significant decrease in FPG (WMD 0.71 mmol/L, 95% CI, 0.43‐1.00 mmol/L, P < .00001) than was DPP‐4is plus Met. However, no differences were found in the reduction of HbA1c (WMD 0.11%, 95% CI, −0.03%‐0.25%, P = .12) or the risk of hypoglycaemic events (RR, 1.02; 95% CI, 0.80‐1.31, P = .86).ConclusionsThis review revealed that, compared to DPP‐4is, SGLT‐2is significantly reduced HbA1c, FPG and body weight without increasing the risk of hypoglycaemia in diabetes treatment.
Millennium Development Goals: Impact on national strategies and spending
Authors: Seyedsayamdost Elham 
Published: June 2017

AbstractThis study reviews the post‐2005 national development strategies of 50 countries from diverse income groups, geographical locations, human development tiers and official development assistance (ODA) levels to assess Millennium Development Goal (MDG) absorption into development planning. Reviewing Poverty Reduction Strategy Papers (PRSPs) and non‐PRSP national strategies, the majority of the development plans have either adopted the MDGs as planning tools or ‘localized’ them in a meaningful way, using diverse adaptation strategies. A high correlation is detected between the income group, PRSP status and ODA reliance of countries, and their propensity to incorporate MDGs in their planning instruments. However, MDG alignment is not coterminous with greater pro‐poor or MDG‐oriented policies. Countries that have not integrated MDGs into their national plans were as likely to allocate government funds to social sectors as MDG aligners.

SummaryObjectiveThe reasons for failure of surgical treatment for mesial temporal lobe epilepsy (MTLE) associated with hippocampal sclerosis (HS) remain unclear. This retrospective study analyzed seizure, cognitive, and psychiatric outcomes, searching for factors associated with seizure relapse or cognitive and psychiatric deterioration after MTLE‐HS surgery.MethodsSeizure, cognitive, and psychiatric outcomes were reviewed after 389 surgeries performed between 1990 and 2015 on patients aged 15–67 years at a tertiary center. Three surgical approaches were used: anterior temporal lobectomy (ATL; n = 209), transcortical selective amygdalohippocampectomy (SAH; n = 144), and transsylvian SAH (n = 36).ResultsWith an average follow‐up of 8.7 years (range = 1.0–25.2), seizure outcome was classified as Engel I in 83.7% and Engel Ia in 57.1% of patients. The histological classification of HS was type 1 for 75.3% of patients, type 2 for 18.7%, and type 3 for 1.2%. Two factors were significantly associated with seizure recurrence: past history of status epilepticus and preoperative intracranial electroencephalographic recording. In contrast, neither HS type, the presence of a dual pathology, nor surgical approach was associated with seizure outcome. Risk of cognitive impairment was 3.12 (95% confidence interval = 1.27–7.70), greater in patients after ATL than in patients after transcortical SAH. A presurgical psychiatric history and postoperative cognitive impairment were associated with poor psychiatric outcome.SignificanceThe SAH and ATL approaches have similar beneficial effects on seizure control, whereas transcortical SAH tends to minimize cognitive deterioration after surgery. Variation in postsurgical outcome with the class of HS should be investigated further.
Study of electromechanical impedance changes caused by modifications of CFRP adhesive bonds

Published: June 2017

AbstractNumerous techniques of nondestructive testing and structural health monitoring of CFRP structural parts are studied. In this research, we focus on electromechanical impedance (EMI) technique. This technique is based on a piezoelectric sensor that is surface mounted on or embedded in the inspected structure. Because of direct and converse piezoelectric effects, the electrical response of the sensor is related to mechanical characteristic of the structure. In the reported research, adhesively bonded CFRP samples were investigated. The EMI characteristics of samples with modified bonds were compared with properly bonded referential samples. The following modifications were considered: prebond thermal treatment, prebond contamination with de‐icing fluid, and precuring of the adhesive. The EMI spectra were investigated searching for anomalies and changes caused by modification of the adhesive bonds. Numerical indexes were used for the comparison of EMI characteristics. The sensitivity of the EMI method to modified bonds was observed.
