Published: February 2018

AbstractBackgroundThe strong relationship between sleep apnoea and atrial fibrillation (AF) is well known. However, it remains unclear whether the sleep quality is related with AF.AimTo evaluate the associations of sleep duration, insomnia and frequent awakening with AF.MethodsA systematic review was conducted in MEDLINE, EMBASE, Cochrane databases from inception through September 2017 to identify studies that evaluate the risk of AF in adults with short sleep duration, long sleep duration, insomnia and/or frequent awakening. Effect estimates from the individual study were extracted and combined using random‐effect, generic inverse variance method of DerSimonian and Laird.ResultsTen observational studies (14 296 314 patients) were enrolled. The pooled odds ratios (ORs) of AF in individuals with short sleep (<6 h) and long sleep (>8 h) were 1.20 (95% confidence interval (CI) 0.93–1.55, I2 = 66%) and 1.24 (95% CI 0.96–1.62, I2 = 58%), respectively. There was no association between increase in sleep duration and AF, with a pooled OR of 0.97 (95% CI 0.84–1.12, I2 = 0%). However, there were significant associations of AF with insomnia and frequent awakening, with pooled ORs of 1.30 (95% CI 1.26–1.35, I2 = 3%) and 1.36 (95% CI 1.13–1.63, I2 = 55%), respectively.ConclusionsOur findings suggest an absence in association between AF and sleep duration but reveal the potential association between AF and both insomnia and frequent nocturnal awakening. As such, the further studies on association of AF and sleep qualities are warranted.
Determinants of housing bubbles' duration in OECD countries

Published: February 2018

AbstractWe study the determinants of housing price bubbles' duration for a set of OECD countries between 1970 and 2015. Our topic of study is of major importance, as duration is a proxy for other dimensions, such as the magnitude of bubbles, the extent of macroeconomic imbalances, and the chance that a rational bubble turns into an irrational one. We answer two related questions: (i) Does prolonged domestic monetary‐policy easing increase the duration of housing price bubbles? (ii) Does prolonged monetary‐policy easing in the United States influence the housing bubbles' duration in other OECD countries? We show that the answer to the first question is a clear yes but that the answer to the second question is not as clear. Our main result is that monetary‐policy tightening can accelerate the termination of a housing bubble. In this sense, our findings provide support for ‘leaning against the wind’ policies.
Monday Effect in the RMW and the Short‐Term Reversal Factors
Authors: Ali Fahad , Ülkü Numan 
Published: February 2018

AbstractWe document that the positive (opposite) Monday or early‐in‐the‐week effect in Fama–French's robust‐minus‐weak (RMW) factor, first reported by Ülkü (2017), is pervasive across international markets, ruling out data‐snooping. As in the United States, the pattern has strengthened over time. Monday effect in RMW is linked to a combination of institutional investor trading pattern and the weekend sound‐mind effect. We devise a test of the external validity of the weekend sound‐mind effect hypothesis: the short‐term reversal factor, which is profitable within its holding period but leads to larger losses subsequently, exhibits a significant negative Monday effect, as predicted by this hypothesis. Mondays buck fads.
Attitudes toward adolescent self‐harm and its prevention: The views of those who self‐harm and their peers
Authors: Doyle Louise 
Published: February 2018

AbstractProblemAdolescent self‐harm is a common phenomenon; however, little is known about young peoples’ attitudes toward self‐harm and what they believe can be done to prevent it. This study aimed to identify adolescents’ attitudes about self‐harm and their perspectives on preventing it.MethodsA cross‐sectional anonymous survey was administered to 856 post‐primary school students across 11 schools in Dublin, Ireland. Attitudes toward self‐harm were captured through a five‐item scale and views on prevention of self‐harm were captured through an open‐ended survey question. Responses from those who self‐harmed and those who did not were compared to identify differences.FindingsSignificant differences were identified between those who self‐harmed and their peers. Those who self‐harmed were less likely to believe that self‐harm was carried out to get attention or was a result of loneliness or depression; they were more likely to believe that self‐harm was impulsive. Findings demonstrated that a majority of young people believed that self‐harm could be prevented and a number of preventative strategies were identified.ConclusionsIt is important that the views of adolescents are incorporated into the design and delivery of youth‐friendly services and that there is a focus on increasing awareness of the youth‐orientated services that currently exist.

Published: February 2018

We investigated the association between working memory (WM) impairment and blood pressure variability (BPV) in very elderly patients. Japanese outpatients ≥80 years who engaged in normal activities of daily living were the study cohort. WM function was evaluated by a simple visual WM test consisting of 3 figures. We considered the number of figures recalled by the patient his/her test score. We defined the patients with a score of 0 or 1 as those with WM impairment and those with scores of 2 or 3 as those without. To investigate the relative risk of WM impairment, we evaluated each patient's 24 hour ambulatory systolic blood pressure (SBP) and its weighted standard deviation (SDSBP), office SBP, and the visit‐to‐visit SDSBP during the 1 year period from the patient's enrollment. A total of 66 patients (mean 84 ± 3.6 years) showed WM impairment, and 431 patients (mean 83 ± 3.1 years) showed no WM impairment. There were no significant differences in 24 hour ambulatory SBP or office SBP between these two groups. However, the WM impairment patients showed significantly higher weighted SDSBP and visit‐to‐visit SDSBP values compared to the no‐impairment group even after adjusting for age. Among these ≥80‐year‐old patients, those with the highest quartile of both weighted SDSBP (≥21.4 mm Hg) and visit‐to‐visit SDSBP (≥14.5 mm Hg) showed the highest relative risk (odds ratio 3.52, 95% confidence interval 1.42‐8.72) for WM impairment. Exaggerated blood pressure variability parameters were significantly associated with working memory impairment in very elderly individuals.
Allodial Land Rights (The Odelsrett) and Early Nineteenth Century Norwegian Nationalism: Propertied Sovereignty as National Sovereignty
Authors: Fuglestad Eirik Magnus 
Published: February 2018

AbstractThe early nineteenth century was a transitional time in western Europe; from the old feudal and imperial order, modern nation states and capitalism emerged. The Norwegian nation state emerged out of the flames of the Napoleonic Wars in 1814. But changes in landed property structures in the eighteenth century lay the ground for Norwegian nationalism in the early nineteenth century. This article explores early nineteenth century nationalism through a focus on property rights and the positive view on theodesrett– an allodial right to land – arguing that an examination of the positive view on theodelsrettcan shed new light on Norwegian nationalism in the early nineteenth century. Such an examination suggests that the Norwegian property structure contributed to reinforcing certain property rights element in the Norwegian nationalism where ownership of landed property and national, popular sovereignty were closely interconnected.

Published: February 2018

ABSTRACTThe thalamus is a part of the diencephalon, containing numerous connections between the forebrain and subcortical structures. It serves an important function as a relay center between the cerebral cortex and the subcortical regions, particularly with sensory information. The thalamus also plays a major role in regulating arousal and the levels of awareness. Distinct vascular distribution of the thalamus give rises to different syndromic presentation of thalamic nuclei infarcts. The clinical records and available imaging studies of patients with confirmed thalamic territory infarcts on magnetic resonance imaging (MRI) at the University Hospital of Rochester were reviewed and analyzed. This analysis was then used to provide an effective summary of thalamic vascular anatomy, the clinical symptoms, and syndromes associated with strokes in the affected territories. Specifically, we review the syndromes associated with classic vascular territories, including the anterior, paramedian, inferolateral, and posterior thalamic nuclei, that are supplied by the polar (tuberothalamic), paramedian, inferolateral (thalamogeniculate), and posterior choroidal arteries, respectively. In addition, we will also review the variant thalamic territories and associated infarction syndromes of the anteromedian, central, and posterolateral territories. This review article is aimed to better the clinical and radiologic understanding as well as the diagnosis of classic and variant thalamic territory infarcts. This article will also briefly touch on the recovery of function after thalamic infarcts.
Sensory expert assessor's learning practices at workplace: Competencies and contexts in sensory evaluation

Published: February 2018

The aim of this study was to identify competencies and learning contexts that are central when a standardized sensory expert assessor conducts food sensory evaluations in an authentic professional context. The aim was to answer the following questions: first, according to accessors, what competencies does sensory evaluation require? Second, what contexts of sensory evaluation do assessors report on? Thirteen assessors from three Finnish food companies were interviewed using semi‐structured thematic interviews to map competencies and development intentions and explain established practices. In the study, 42% of analysis units described individual evaluation contexts, 53% described collaborative interactional contexts, and 5% described collaborative knowledge creation contexts. The findings contribute to the explanation of how assessors learn extensively from each other in collaborative interactional and knowledge creation contexts. Assessors' learning practices and abilities to work collaboratively in interactional and knowledge creation contexts need to be ensured for the development of expertise.Practical applicationsOur findings suggest that an important aspect of enhancing learning and achieving consistent results in assessors' work is to increase collaborative and knowledge creating practices in sensory training, in addition to training individual skills. Such practices are embedded in daily practices, especially the cases when product defects were sought and discussed. Advanced practices included: learning, sharing, and reviewing both external and in‐house consumer panel feedback, developing methods to moderate small‐panel evaluations and developing a product vocabulary collectively between the assessors. These practices supported sensory expert assessors in developing their personal and collective expertise in the workplace.

Published: February 2018

AbstractCake is a popular food around the world, however, it is considered as unhealthy due to its high fat and sucrose content. To satisfy customers' demand for a low fat and sucrose cake, in this research both sucrose and fat content of the cake were reduced by using rebaudioside A (Reb A; as a natural sucrose replacer) and inulin (as a natural fat replacer) at 0%, 25%, 50%, 75%, and 100%. The water content of different formulation was adjusted to obtain a constant batter viscosity similar to the control (3,757 cP). By reducing sucrose and fat content up to 50%, water activity increased and the cakes became more asymmetrical. However, other physical properties including baking weight loss, height, volume, crust color, and texture were similar to those of the control. Higher levels of replacement (75% and 100%) resulted in remarkable loss of different quality attributes. These samples showed higher water activity and baking loss, lower volume, harder texture, darker color, and highly asymmetrical shape. Thus, successful reduction of both fat and sucrose in cakes is possible by using inulin and Reb A at replacement levels no more than 50%.Practical applicationsCustomers' demand for healthy and yet tasty and high‐quality foods is increasing around the world. Therefore, finding applicable and safe methods to produce such products is of great interest in the food manufacturing to satisfy customers. Health conscious customers avoid consumption of cakes because it contains high sucrose and fat content. Many studies have been performed to reduce either fat or sucrose content, while a few studies are available to show the reduction of both fat and sucrose in the same product. This study indicates the results of an applicable method to reduce fat and sucrose content of cakes simultaneously. Using rebaudioside A (as a natural sucrose replacer) and inulin (as a natural fat replacer) up to 50% of sucrose and fat content of cakes were reduced and the resulting cake had very similar physical properties to the control.
Lossless Compression of All Vehicle Trajectories in a Common Roadway Segment
Authors: Lovell David J. 
Published: February 2018

AbstractThis article describes a method for compressing position and identification data for files containing comprehensive trajectory records of all vehicles traversing the same roadway segment over an arbitrary time period, in such a way that no loss of information content occurs. Such complete trajectory records are important for the study of traffic flow theory and could become increasingly relevant as test data against which to study the behavior of autonomous vehicles in a mixed traffic environment. Compression steps include differential encoding, motion prediction, and parsimonious binary storage, plus steps that are unique to the context of vehicle trajectories, including vehicle ID numbers and lane occupancy. The effectiveness of the compression is due, in part, to the strong correlations between positions (and speeds) of vehicles traveling near each other, as well as recognition that certain trajectory artifacts change with spatial and temporal frequencies much lower than the sampling rates. The algorithm is demonstrated on two sets of publicly available complete trajectory records, and compression performance statistics are given. Compression ratios in the range 10:1 to more than 20:1 are achieved for the sample files.
B‐type natriuretic peptide is a useful biomarker for the estimation of volume overload in children with hypertension on peritoneal dialysis
Authors: Lee Joo Hoon , Park Young Seo 
Published: February 2018

ABSTRACTAimThe aim of the present study was to evaluate the usefulness of serum B‐type natriuretic peptide (BNP) as a biomarker of fluid retention in hypertensive children on peritoneal dialysis (PD).MethodsHypertensive children on PD were included. The changes (∆) of body weight (BWt), blood pressure (BP) and serum BNP at initial and follow‐up periods were reviewed. Data are presented as mean ± standard deviation (median, minimum – maximum). Wilcoxon signed‐rank test was used to evaluate the changes in BWt, BP, and BNP. Linear regression analysis was applied for the correlation between the changes of BNP and BP.ResultsA total of 56 hypertensive events were evaluated in 30 patients. Initial findings were BWt 30.5 ± 22.4 (26.5, 3.0–93.5) kg, systolic BP (SBP) 153.3 ± 21.5 (150, 110–241) mmHg, diastolic BP (DBP) 100.1 ± 22.3, (99.5, 49–181) mmHg, BNP 3579.3 ± 6328.9 (1198.5, 305–22 028) pg/mL. Follow‐up results were BWt 29.1 ± 21.3 (25.0, 3.12–86) kg, SBP 116.4 ± 17.8 (117.5, 82–150) mmHg, DBP 73.3 ± 14.2 (75.0, 42.0–101.0) mmHg, BNP 63.5 ± 49.2 (60.5, 2–261) pg/mL. ∆SBP (−23.1 ± 13.8, −22.8, −46.9 ‐ 22.5%, P < 0.001), ∆DBP (−24.1 ± 19.2, −24.7, −55.6 – 23.2%, P < 0.001) and ∆BNP (−93.5 ± 8.1, −96.7, −99.9 – ‐61.0%, P < 0.001) dropped significantly after reduction of ∆BWt (−4.8 ± 4.7, −4.8, −18.7 – 5.6%, P < 0.001). The ∆BNP were significantly correlated with ∆SBP (adjusted R square = 0.221, P < 0.001) and ∆DBP (adjusted R square = 0.203, P < 0.001).ConclusionsSerum B‐type natriuretic peptide should be measured in hypertensive patients on PD to evaluate the volume status.
Linking Quality with Social and Financial Performance: A Contextual, Ethics‐Based Approach
Authors: Sila Ismail 
Published: February 2018

The objectives of this study are to test the relationships among total quality management (TQM) practices, corporate social performance (CSP), and financial and market performance (FMP); and to determine the moderating effects of two contextual factors—country and sector—on these relationships through the lenses of several theories, including stakeholder theory, integrative social contracts theory (ISCT), and legitimacy theory. Using data from the various sectors of the economies of two developing countries, Turkey and North Cyprus (NC), we tested the proposed model utilizing structural equation modeling (SEM). The results from both samples supported the proposed model relationships, providing support for the idea that focusing on stakeholder interests embedded in various TQM practices helps improve both CSP and FMP. Country of origin had no moderating effects on these relationships, whereas sectoral effects were highly significant. The study also discusses the managerial and research implications of these findings.
Unpacking the Effects of Competing Mandates on Agency Performance
Authors: Carrigan Christopher 
Published: February 2018

AbstractPublic administration scholars and practitioners uniformly agree that saddling agencies with multiple mandates breeds dysfunction and impedes performance. However, less is known about the mechanisms by which combining purposes has these effects. This study of a broad set of U.S. federal agencies finds support for the conventional wisdom by showing that agencies balancing greater numbers of programs perform worse. The analysis further suggests that such organizations struggle largely because they are more likely to be forced to simultaneously adopt conflicting stances toward program targets. Moreover, when programs force agencies into conflicts in which they are asked to both support and restrain the same target, the resulting uncertainty among personnel regarding agency priorities helps explain why operations are negatively impacted. Thus, it is not simply that accumulating missions impedes agency performance but rather how those competing mandates interact that can define whether an agency will struggle to achieve its objectives.
Architecture and morphodynamics of subcritical sediment waves in an ancient channel–lobe transition zone
Authors: Hofstra Menno , Peakall Jeff , Hodgson David M , Stevenson Christopher J 
Published: February 2018

AbstractIn modern systems, submarine channel–lobe transition zones show a well‐documented assemblage of depositional and erosional bedforms. In contrast, the stratigraphic record of channel–lobe transition zones is poorly constrained, because preservation potential is low and criteria have not been established to identify depositional bedforms in these settings. Several locations from an exhumed fine‐grained base of slope system (Unit B, Laingsburg depocentre, Karoo Basin, South Africa) show exceptional preservation of sandstone beds with distinctive morphologies and internal facies distributions. The regional stratigraphic context, lack of a basal confining surface, wave‐like morphology in dip section, size and facies characteristics support an interpretation of subcritical sediment waves within a channel–lobe transition zone setting. Some sediment waves show steep (10 to 25°) unevenly spaced (10 to 100 m) internal truncation surfaces that are dominantly upstream‐facing, which suggests significant spatio‐temporal fluctuations in flow character. Their architecture indicates that individual sediment wave beds accrete upstream, in which each swell initiates individually. Lateral switching of the flow core is invoked to explain the sporadic upstream‐facing truncation surfaces, and complex facies distributions vertically within each sediment wave. Variations in bedform character are related to the axial to marginal positions within a channel–lobe transition zone. The depositional processes documented do not correspond with known bedform development under supercritical conditions. The proposed process model departs from established mechanisms of sediment wave formation by emphasising the evidence for subcritical rather than supercritical conditions, and highlights the significance of lateral and temporal variability in flow dynamics and resulting depositional architecture.

Published: February 2018

Research on the acute responses to exercise in pregnancy is scarce, especially for women affected by gestational diabetes mellitus (GDM). The aim of this study was to investigate responses to a single bout of exercise performed multiple times throughout the pregnancy in women diagnosed with GDM. Data from 18 pregnant women (aged: 32.8 ± 3.8) diagnosed with GDM, treated with diet only, were analyzed. Participants’ pre‐pregnancy body mass index was 24.4 ± 4.9 kg/m2, 50% of them were nulliparous, and 50% of the sample regularly exercised before the pregnancy. The exercise intervention consisted of an individual structured aerobic and resistance exercise program performed twice per week from the time of diagnosis until at least the 36th week of pregnancy. The exercise program included 20 minutes of aerobic exercise, 20‐25 minutes of resistance exercise, and 10 minutes of cool down. Maternal heart rate, systolic and diastolic blood pressure, temperature and fetal heart rate were measured at every exercise session, along with blood glucose on 3 occasions. In total, 365 exercise sessions were analyzed (85 in the second trimester and 280 in the third trimester), on average 20.3 ± 7.7 per participant. Heart rate and fetal heart rate were elevated during both the aerobic and resistance parts of the exercise session (P < .01) in comparison with the baseline while systolic and diastolic blood pressure did not change in the total sample. There was a slight elevation in tympanic membrane temperature during the aerobic part of the session (P < .01). All parameters returned to baseline levels by the end of the session. Glucose levels dropped from the baseline, from 4.7 ± 0.6 to 3.9 ± 0.4 mmol/L (P < .01). There were no differences in responses to exercise between the second and third trimesters, nor between pre‐pregnancy exercisers and non‐exercisers. The combination of aerobic and resistance exercise for women diagnosed with GDM does not have harmful short‐term effects if performed according to guidelines. Likewise, exercise can be considered useful for controlling hyperglycemia in pregnancy for women affected by GDM.
