The value of capture: Taking an alternative approach to using lecture capture technologies for increased impact on student learning and engagement
Authors: Witton Gemma 
Published: May 2016

AbstractLecture Capture technologies are becoming widespread in UK Higher Education with many institutions adopting a capture‐all approach. Installations of capture devices in all teaching rooms and lecture theatres, scheduled recordings through integration with timetabling and automated distribution through virtual learning environments are swiftly becoming the norm. Capturing lectures has been shown to have a positive impact on student satisfaction, but numerous studies have shown little or no positive impact on student attainment as a result of capturing lectures. This article explores an alternative approach to the use of capture technologies in a pilot study at the University of Wolverhampton. The output of the pilot evaluation is a theoretical model recommending a shift in focus away from the conventional use of the technology for capturing lectures. It advocates a move toward the purposeful use of capture technologies to create content which adds value to student learning and increases engagement, which may ultimately lead to a positive impact on student attainment. The findings have implications for policy and practice around the use of capture technologies. Future work is described in the context of the project findings.

AbstractPurposeThe purpose of this 2‐year randomized controlled clinical trial was to assess the differences in implant survival rates, soft tissue preservation, patient centered outcome and crestal bone changes applying the minimally invasive (MI) flapless approach for single implant placement compared to flapped implant surgery (FS).Materials and methodsSubjects eligible for this study were randomly assigned into two groups: MI or FS. Items of evaluation were the following: implant installation position, soft tissue healing, post‐surgical pain, soft tissue outcome, marginal bone loss (MBL), and implant survival rate.ResultsForty subjects (14 women and 26 men, 20 in MI group and 20 in FS group with a mean of 39 ± 13.2 years old) were included in the study. None of the implants demonstrated dehiscence or loss during the follow‐up. Subjects in MI group showed significantly lower post‐surgical pain and significantly less wound healing index scores at 1‐week follow‐up. The width of keratinized mucosa decreased from a mean of 4.2 ± 1.6 mm pre‐surgically to 3.7 ± 1.1 mm at crown delivery but remained stable at 2‐year follow‐up in MI group. At every appointment in the study, no statistical significant difference of PD and MBL was found between the two groups.ConclusionCompared with FS, single implants placed applying the MI technique in selected subjects showed advantages in improving patient comfort and decreasing post‐implant placement soft tissue reaction. Meanwhile, implants with MI approach have the same level of MBL and high success rates as FS procedure at 2‐year follow‐up. The deduction of keratinized mucosa is very limited and the width of KM remained stable with MI approach at 2‐year follow‐up.

Published: May 2016

AbstractTwo complementary experimental techniques have been used to study the evolution of crack‐tip strain fields in a thin (plane stress dominated) compact tension sample following a single overload (OL) event. The total strain has been characterised at the surface by digital image correlation (DIC), while the elastic strain field in the bulk (interior) behaviour has been characterised by means of synchrotron X‐ray diffraction (XRD). Surface and bulk information allowed us to visualise the evolution of the strain fields before the OL event, during the OL event, just after it and at various stages after it. Unlike previous work, complete 2D maps of elastic strains around the crack‐tip were acquired at 60 µm spatial resolution by XRD. The strain data were used to estimate the effective crack driving force at the surface and at the mid plane. The DIC shows less crack opening displacement after overload and the XRD a lower crack‐tip peak stress after OL until the crack has grown past the compressive crack‐tip residual stress after which the behaviour returned to that for the baseline fatigue response. While the compressive residual stress introduced by the OL offsets the crack‐tip stress field as it grows through the overload plastic zone, the changes in crack‐tip stress over each cycle are the same before and at all stages after OL.
Numerical Study on Behavior of Groundwater Flow in Single Rough Fractures Under Mechanical Effect
Authors: Jeong Woochang 
Published: May 2016

AbstractThis paper numerically investigates the characteristics of groundwater flow in spatially correlated variable aperture fractures under the mechanical effect. Spatially correlated aperture distributions are generated using the geostatistical method (i.e., turning bands algorithm in this study). To represent a nonlinear relationship between the effective normal stress and the fracture aperture, a simple mechanical formula is combined with a local flow model. Numerical results indicate that the groundwater flow is significantly affected by the geometry of aperture distribution, varying with the applied effective normal stress as well as the spatial correlation length of aperture distribution. Moreover, using the flow results simulated in this study, two empirical formulae are proposed: (1) the first one (modified Louis formula) is to represent the relationship between the effective normal stress and the effective permeability of fracture and (2) the second one is to represent the relationship between relative roughness and effective permeability.
Structure of the male copulatory apparatus in Prognathorhynchus busheki (Platyhelminthes, Kalyptorhynchia)
Authors: Doe David A. , Smith Julian P.S. 
Published: May 2016

AbstractGnathorhynchidae is a diverse taxon of predatory eukalyptorhynch flatworms characterized by an armed proboscis. Their present taxonomy is not concordant with what we know of their phylogeny. Further progress in this area is hindered by a lack of information concerning their morphology. As recent studies have shown, a historical reliance on live observations for species descriptions has resulted in a number of errors and omissions. Here, we redescribe the anatomy of the male copulatory organ of Prognathorhynchus busheki using transmission electron and confocal microscopy, correcting several errors in the original description. Furthermore, we use these results to update our understanding of the anatomy and evolution of male copulatory organs in Gnathorhynchidae and in Platyhelminthes more generally.

Authors: Hofmann Stefan G. , Andreoli Giovanbattista , Carpenter Joseph K. , Curtiss Joshua 
Published: May 2016

AbstractObjectiveSome evidence suggests that Hatha yoga might be an effective practice to reduce anxiety. To examine the effect of Hatha yoga on anxiety, we conducted a meta‐analysis of relevant studies extracted from PubMed, PsycINFO, the Cochrane Library, and manual searches.MethodThe search identified 17 studies (11 waitlist controlled trials) totaling 501 participants who received Hatha yoga and who reported their levels of anxiety before and after the practice. We estimated the controlled and within‐group random effects of the practice on anxiety.ResultsThe pre–post within‐group and controlled effect sizes were, Hedges’ g = 0.44 and Hedges’ g = 0.61, respectively. Treatment efficacy was positively associated with the total number of hours practiced. People with elevated levels of anxiety benefitted the most. Effect sizes were not moderated by study year, gender, presence of a medical disorder, or age. Although the quality of the studies was relatively low, the risk of study bias did not moderate the effect.ConclusionHatha yoga is a promising method for treating anxiety. However, more well‐controlled studies are needed to compare the efficacy of Hatha yoga with other more established treatments and to understand its mechanism.
Advertising Expensive Mortgages

Published: May 2016

ABSTRACTUsing information on advertising and mortgages originated by subprime lenders, we study whether advertising helped consumers find cheaper mortgages. Lenders that advertise more within a region sell more expensive mortgages, measured as the excess rate of a mortgage after accounting for borrower, contract, and regional characteristics. These effects are stronger for mortgages sold to less sophisticated consumers. We exploit regional variation in mortgage advertising induced by the entry of Craigslist and other tests to demonstrate that these findings are not spurious. Analyzing advertising content reveals that initial/introductory rates are frequently advertised in a salient fashion, where reset rates are not.
A Tale of Two Runs: Depositor Responses to Bank Solvency Risk
Authors: IYER RAJKAMAL , PURI MANJU , RYAN NICHOLAS 
Published: May 2016

ABSTRACTWe examine heterogeneity in depositor responses to solvency risk using depositor‐level data for a bank that faced two different runs. We find that depositors with loans and bank staff are less likely to run than others during a low‐solvency‐risk shock, but are more likely to run during a high‐solvency‐risk shock. Uninsured depositors are also sensitive to bank solvency. In contrast, depositors with older accounts run less, and those with frequent past transactions run more, irrespective of the underlying risk. Our results show that the fragility of a bank depends on the composition of its deposit base.

Published: May 2016

AimTo provide in New Caledonian school children (i) the prevalence of rheumatic heart disease (RHD) detected by annual screening program using new World Heart Federation diagnostic criteria; (ii) the point prevalence of acute rheumatic fever (ARF); and (iii) to investigate socio‐demographic risk factors associated with RHD.MethodsThis study linked data from national ARF/RHD programs by combining ARF incidence data from the register with RHD prevalence data from echocardiographic screening data for a single age year of the population for overall point prevalence ARF/RHD rates. For the analysis, cases of echocardiographic detection of RHD are presumed to be synonymous with undiagnosed ARF. All results were weighted to minimise the bias introduced from absent pupils of each annual screening program. Incidence and prevalence were age‐standardised to the WHO World Standard Population. Each 2013 cumulative prevalence of definite and borderline RHD was studied using a multivariate logistic regression adjusted for socio‐demographic factors.ResultsThe overall age‐standardised incidence of clinical and undiagnosed ARF (i.e. echocardiographic‐detected RHD) was combined as point prevalence and estimated to be 99/10 000 cases in 2012 and 114/10 000 cases in 2013. This included 40/10 000 prevalent cases of asymptomatic RHD detected by screening each year. Being Melanesian, OR 23.2 (95% CI: 3.4–157.3), or Polynesian, OR 21.5 (95% CI: 2.9–157.7), was associated with a higher prevalence of having definite RHD compared with being Caucasian. Being a girl was associated with a higher risk of having borderline RHD, OR 1.9 (95% CI: 1.03–3.3).ConclusionWithout echocardiographic screening, ARF/RHD burden is substantially underestimated.

Published: May 2016

AimThis study describes clinical staff opinions on the availability and suitability of resources to provide trauma care to children and their families and any perceived strengths, gaps and potential interventions to strengthen care.MethodsA mixed‐method study was conducted in five Australian paediatric trauma centres. The trauma coordinator at each site participated in a structured interview to determine models of care and trauma activity at their site. This informed the development of an electronic survey, which sought staff opinion on child and family access to services and perceived gaps in care.ResultsFive trauma coordinators were interviewed, and 214 clinicians (medical, nursing, allied health) from New South Wales, Victoria, South Australia and Queensland completed the survey. Each site had a trauma director and coordinator, and there was variance in resource availability. Almost all survey participants (92.5%) considered their hospital met the physical needs of injured children, 68.2% thought that the psychosocial needs of children were met and 82.1% thought that the needs of families were met. The least accessible services reported were clinical psychology/family counselling, mental health and behaviour management services. No routine follow‐up support services post‐discharge for the child or their families were identified.ConclusionStaff providing care for injured children report that physical needs are better met than psychosocial needs. There is variability in resource levels across paediatric trauma centres. A coordinated model of care that provides psychosocial care both during hospitalisation and post‐discharge could reduce this gap in care for injured children and their families.

Published: May 2016

AbstractThe relationship between initial population densities (Pi) of Meloidogyne hapla on growth of three rose rootstocks (Rosa corymbifera ‘Laxa’, R. multiflora and R. canina ‘Inermis’) and nematode population development was studied. Each plant species was inoculated with ranges of nematode densities of 0, 0.062, 0.125, 0.25, 0.50, 1, 2, 4, 8, 16, 32, 64 and 128 second‐stage juvenile/g soil and were allowed to grow for 9 weeks. Seinhorst yield model was fitted to total fresh biomass data of the rootstocks. The tolerance limits (T) were 0.04, 0.09 and 0.01 J2/g soil and the minimum yield (m) 0.65, 0.47 and 0.43 for R. corymbifera ‘Laxa’, R. multiflora and R. canina ‘Inermis’, respectively. The reproductive factor (Pf/Pi) was highest at low initial nematode densities for all rootstocks and then decreased to below maintenance level with increasing initial population densities. Root gall severity consistently increased with initial nematode population density. Furthermore, number of root galling showed a strong positive relationship with final nematode population per gram root fresh weight. The relation between Pi and Pf was also fitted to the Seinhorst population model (Pf = (M*Pi)/Pi + M/a). Rosa multiflora supported the population of M. hapla to a maximum population density (M) of 27.53 J2/g soil with an estimated average maximum multiplication rate (a) of 24.39. For R. corymbifera ‘Laxa’ and R. canina, the maximum multiplication rate was 4.34 and 3.62 and the maximum population density 6.08 and 4.78 J2/g dry soil, respectively. Hence, it was demonstrated that all three rootstocks were susceptible to even low initial nematode densities and therefore are considered good hosts for M. hapla.

Published: May 2016

AbstractAimThe aim of this study was to investigate the association of an insertion/deletion (I/D) polymorphism in angiotensin‐converting enzyme (ACE) gene with serum ACE level in relation to the type and severity of malformations from congenital anomalies of the kidney and urinary tract (CAKUT) spectrum.MethodsA group of 134 Bulgarian children with CAKUT divided into four subgroups according to the leading malformation and 109 controls were genotyped by classical polymerase chain reaction. The quantitative determination of serum ACE was performed by ELISA method.ResultsA significant elevation of DD‐genotype was observed in high‐grade hydronephrosis compared to low‐grade (43% vs. 9%). The carrying of DD‐genotype was associated with higher risk for severe hydronephrosis with OR = 7.5 (95% CI: 1.242÷45.278; P = 0.028). Also, elevated serum ACE concentrations in patients with high‐grade compared to low‐grade hydronephrosis (237.4 ± 45 ng/mL vs 180.5 ± 64 ng/mL; P = 0.0065) were found. ACE level was significantly lower in patients with unilateral renal agenesis; hypo/dysplasia and multicystic dysplastic kidney (156.6 ± 54 ng/mL) than controls (200.6 ± 56.7 ng/mL; P = 0.005) and the remaining CAKUT subgroups.ConclusionThe DD genotype of I/D ACE polymorphism encodes the highest serum ACE level may be an additional genetic risk factor contributing to the severe hydronephrosis in Bulgarian patients with obstructive uropathies in contrast to other investigated categories of CAKUT malformations.
Can data in optometric practice be used to provide an evidence base for ophthalmic public health?
Authors: Slade Sarah V. , Davey Christopher J. , Shickle Darren 
Published: May 2016

AbstractPurposeThe purpose of this paper is to investigate the potential of using primary care optometry data to support ophthalmic public health, research and policy making.MethodsSuppliers of optometric electronic patient record systems (EPRs) were interviewed to gather information about the data present in commercial software programmes and the feasibility of data extraction. Researchers were presented with a list of metrics that might be included in an optometric practice dataset via a survey circulated by email to 102 researchers known to have an interest in eye health. Respondents rated the importance of each metric for research. A further survey presented the list of metrics to 2000 randomly selected members of the College of Optometrists. The optometrists were asked to specify how likely they were to enter information about each metric in a routine sight test consultation. They were also asked if data were entered as free text, menus or a combination of these.ResultsCurrent EPRs allowed the input of data relating to the metrics of interest. Most data entry was free text. There was a good match between high priority metrics for research and those commonly recorded in optometric practice.ConclusionsAlthough there were plenty of electronic data in optometric practice, this was highly variable and often not in an easily analysed format. To facilitate analysis of the evidence for public health purposes a UK based minimum dataset containing standardised clinical information is recommended. Further research would be required to develop suitable coding for the individual metrics included. The dataset would need to capture information from all sectors of the population to ensure effective planning of any future interventions.

BackgroundIschemic cardiomyopathy (ICM) can provide the substrate for ventricular tachycardia (VT).ObjectiveTo map noninvasively with high resolution the electrophysiologic (EP) scar substrate, identify its relationship to reentry circuits during VT, and stratify VT risk in ICM patients.MethodsNoninvasive high‐resolution epicardial mapping with electrocardiographic imaging (ECGI) was performed in 32 ICM patients (17 with clinical VT, 15 without VT). Abnormal scar EP substrate was determined based on electrogram (EGM) amplitude (as percentage of maximal peak‐to‐peak voltage over the entire ventricular epicardium; total scar [TS] < 30%; dense scar [DS] < 15%), fractionation, and presence of late potentials (LPs). Scar burden was defined as the ratio of the scar size to the total epicardial surface area. The VT activation pattern was mapped and correlated with the EP substrate to identify components of the reentry circuit.ResultsPatients with VT had higher scar burden (TS: 51.0 ± 9.3% vs 36.5 ± 5.4%, P < 0.05; DS: 29.5 ± 7.3% vs 16.8 ± 6.8%, P < 0.05) with lower normalized unipolar EGM voltage (TS: 0.107 ± 0.027 vs 0.153 ± 0.031, P < 0.05; DS: 0.073 ± 0.023 vs 0.098 ± 0.026, P < 0.05), greater prevalence of fractionated EGMs (TS: 44.1 ± 10.6% vs 26.8 ± 6.3%, P < 0.05; DS: 50.8 ± 10.8% vs 30.9 ± 7.0%, P < 0.05), and LPs (TS: 26.8 ± 10.7% vs 15.8 ± 5.3, P < 0.05). VTs were mapped in eight patients; the reentry circuits were closely related to the EP substrate.ConclusionsECGI noninvasively identified scar EP substrate that underlies abnormal conduction in ICM patients. It identified regions within the scar that aligned with critical elements of the reentry circuit during VT. ECGI can potentially be used for VT risk stratification in ICM patients.

Low marital satisfaction has been shown to be a risk factor for early parenthood and parent‐child relationship problems (Erel & Burman, ; McHale, ). The aim of this study was to assess how parental reports of marital satisfaction related to family alliance and coordination in the observed triadic interaction. The study group included 120 families. Marital satisfaction was evaluated during pregnancy, at 4 months, and at 18 months using the Revised Dyadic Adjustment Scale (RDAS; Busby, Christensen, Crane & Larsson, ) for both parents. Mother‐father‐child interaction was analyzed in the Lausanne Triadic Play setting and coded using the Family Alliance Assessment Scale (Favez, Lavanchy Scaiola, Tissot, Darwiche & Frascarolo, ) when the child reached 18 months of age. The mother's higher marital satisfaction at every measuring point was associated with a cooperative family alliance and/or higher family coordination at 18 months. The father's experience of marital satisfaction was not related to family interaction at any assessment point. Our study suggests that a mother's experience of lower marital satisfaction during pregnancy may be an early sign of later problems in family relationships.
