Insurance demand in emerging Asian and OECD countries: a comparative perspective
Authors: Akhter Waheed , Pappas Vasileios , Khan Saad Ullah 
Published: February 2020

PurposeIn this paper, we aim to assess insurance demand across selected Asian and OECD countries during the period of the global financial crisis.Design/methodology/approachWe collected data from 55 emerging Asian and OECD countries during the period of the global financial crisis. Our methodology relies on panel regressions. Separate models are run for the Asia/OECD economies and a follow-up distinction between high/low-income regions is also made.FindingsWe find that global financial crisis affects negatively the general insurance demand particularly in high-income region. Higher dependency ratio in Asia tends to decrease insurance demand, whereas education in case of Asia positively influences insurance demand indicating that higher literacy rate can be helpful to capture the potential customers. Our results further reveal that life insurance is an important driver for insurance demand in OECD countries, whereas general insurance demand is higher in the Asian economies.Research limitations/implicationsA limitation of this study is that data sets employed do not differentiate between different life and general insurance products.Practical implicationsThis study is helpful for regulators, policymakers and insurance providers to evaluate, assess and monitor insurance demand in relevant countries.Originality/valueThis is one of the pioneering studies that have assessed insurance demand among emerging Asian and OECD countries during the period of the global financial crisis.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/IJSE-08-2019-0523
The reverse gender divide in the United Arab Emirates
Authors: Ashour Sanaa 
Published: February 2020

PurposeMany studies have discussed the pre-eminence of females in higher education in terms of numbers as well as academic performance. This global phenomenon has appeared in many countries, including the United Arab Emirates (UAE). The aim of this study is to identify the social, cultural and familial factors underlying this phenomenon in the UAE.Design/methodology/approachAlthough the study focuses on the university stage, the undergraduate student is the product of an educational process that begins at school age; therefore, some factors related to the schooling stage are also discussed. The study conceptualises gender differentiation as an outcome of both socialisation processes and rational choice factors.FindingsAnalysing data drawn from a total of 292 undergraduates and 18 experts using questionnaires, it finds that socialisation mechanisms at home and schools, rational choice motivations and other factors such as socially constructed, non-cognitive traits of females shape these differences. The implications of these results for policymakers and future research are discussed.Practical implicationsIncreasing access of males to higher education is not merely the responsibility of family and schools but also requires commitment by policy-makers.Originality/valueThe paper presents a significant departure from the largely American and European literature on gender and education, by offering a broader knowledge of this phenomenon in another regional and national context.

Published: February 2020

AbstractTransboundary crises, incidents and disasters, such as chemical spills, airplane crashes and critical infrastructure breakdowns, involving multiple levels and domains of governance pose a particular set of challenges. These challenges also pertain to the investigation and learning phase of a crisis. We study a typical transboundary case: the crash of a Malaysia Airlines Flight 17 (MH17), with 298 people on board from a variety of nationalities but the majority from the Netherlands, that crashed in Ukraine in a conflict zone near the Russian border. The MH17 case contains valuable lessons on transboundary disaster investigations. The Dutch Safety Board (DSB) took the lead of the international independent investigation into the causes of the crash. With an international group of stakeholders, the DSB investigated a crash that resulted from a bilateral conflict, requiring the support from Ukraine's powerful neighbour Russia that meanwhile stood accused of withholding evidence and supporting Ukrainian separatists. Retrieving evidence and researching the causality of the crash was no easy task. If countries wish to follow their ambition to learn from accidents in order to “prevent the past repeated,” they may more often need to investigate such transboundary cases. This case study probes into how challenges that are typical to transboundary crises affected the accident investigation into the MH17 disaster. We search for lessons on transboundary accident investigation that transcend the boundaries of this single case. Such lessons may prove invaluable for learning from future accidents.

Published: February 2020

In this research, Melissa officinalis essential oil was encapsulated through ultrasonication by using different ratios of whey protein isolate/sodium caseinate as coating material. Flavoured yoghurt was generated by adding microcapsules; the release behaviour of the essential oil was characterised over a 21‐day storage period. The released essential oil was quantified by dispersive liquid–liquid microextraction followed by gas chromatography. The results showed that the antioxidative activity of yoghurt samples was increased by the incorporation of encapsulated essential oil. Therefore, the use of microcapsules containing M. officinalis essential oil could be a suitable method for producing nutraceutical foods with antioxidant properties.

AbstractBackgroundOral wounds inevitably come into contact with saliva which can affect the time needed for bleeding to stop. The influence of saliva can be non‐specific, related to dilution of blood, and/or mediated by salivary factors that affect haemostasis directly. The aim of this study was to assess if mixing blood with an individual's saliva would affect the rate of its coagulation measured by global coagulation tests, prothrombin time (PT) and activated partial thromboplastin time (APTT).MethodsThe study included 30 healthy non‐smoking volunteers. Paired blood and unstimulated saliva samples were obtained from each participant and PT and APTT were determined in blood, blood + saliva and blood + water mixtures. Coagulation tests were performed using the mechanical clot detection method.ResultsPT was significantly longer in both blood + saliva and blood + water mixtures compared to blood alone. APTT was significantly longer only in blood + water mixture compared to blood.ConclusionsSimilarly prolonged PT in both mixtures suggests that both saliva and water prolong coagulation evenly due to their non‐specific effect of blood dilution. The finding that APTT was significantly prolonged only when blood was mixed with water could indicate presence of tissue factor in saliva, however, in a concentration too low to influence the results of PT.

Published: February 2020

AbstractBackgroundColorectal cancer remains a common cancer in the western world, with liver resection being the only potentially curative option for isolated colorectal cancer liver metastases (CRCLM). Cancer is a disease of aging, with the optimum management of elderly patients with CRCLM presenting an ongoing dilemma.MethodsWe analysed the outcome of CRCLM using prospectively collected patient data from the multidisciplinary Treatment of Recurrent and Advanced Colorectal Cancer registry, collected from July 2009 to July 2018 at 12 Australian hospitals.ResultsOf 2742 patients with metastatic colorectal cancer, liver‐limited disease was present in 977 (36%) patients, of whom 338 (35%) underwent hepatic resection. Resection rates varied with age, including 186 (43%) of 428 patients aged 64 years and younger, 99 (40%) of 245 aged 65–75 years and 53 (17%) of 303 aged 76 and older (P < 0.001). The 30‐day mortality rate was 0.9%. Median survival post resection also varied with age, 96 versus 89 versus 68 months (P < 0.001). In a separate analysis of the oldest patients, those aged over 80 years, where only 11% underwent resection, the median survival was 49 months.ConclusionThe operative mortality for patients undergoing liver resection at Australian hospitals is low. With advancing age, the rate of liver resection of CRCLM and the post‐resection survival decline. However, excellent survival outcomes can be achieved in selected elderly patients.

AbstractObjectivesTo analyze a modified biphasic phycogenic biomaterial in comparison with anorganic bovine bone in maxillary sinus floor elevation in humans.Material and methodsEight male patients in need of bilateral two‐stage sinus floor elevation were consecutively recruited for this randomized split‐mouth study. A combination of autogenous cortical bone (ACB, 20%) and anorganic bovine bone (ABB, 80%) (ACB + ABB group) or ACB (20%) and modified biphasic phycogenic material (BP, 80%) (ACB + BP group) were randomly assigned to graft each sinus. Patients were followed up for 6 months post‐surgery when bone samples were collected for analysis.ResultsRadiographically, bone height gain was statistically higher in the ACB + ABB versus the ACB + BP group. While the analysis of the biological compartments showed differences in non‐mineralized tissue (39.15 ± 20.97% vs. 65.87 ± 28.59%, ACB + ABB vs. ACB + BP respectively; p = .018) and remnant biomaterial particles (22.62 ± 17.01% vs. 7.96 ± 8.57%, respectively; p = .028), the percentage of mineralized tissue (38.23 ± 17.55% vs. 24.14 ± 24.66%, respectively; p = .398) showed no statistically significant difference. In contrast, ACB + ABB biopsies showed higher Musashi‐1‐positive cells per mm2 compared to ACB + BP biopsies (811.49 ± 875.30 vs. 236.90 ± 280.81; p < .018), where the fusiform cells corresponded mainly with fibroblasts, as demonstrated by ultrastructural analysis.ConclusionBoth combinations of materials exhibited bone formation after 6 months of healing in the maxillary sinus cavity. However, the combination with biphasic phycogenic biomaterial induced a higher radiographical vertical resorption and graft collapse in comparison with the combination with anorganic bovine bone, possibly due to a higher remodeling of the graft.
Improvement of battery lifetime in software‐defined network using particle swarm optimization based cluster‐head gateway switch routing protocol with fuzzy rules

Published: February 2020

AbstractThe software‐defined network (SDN) is one of the network architectures, in which the data plane and control plane is divided from each other, and the network can be handled using a sensibly centralized controller and this method is adopted to reconfigure the wireless sensor network automatically. In this article, to implement the SDN in MANET, in which control nodes can be chosen in SDN dynamically for the activation of MANET function to allocate the works to other mobile nodes to the base station. However, in the field of mobile ad hoc networks, the network lifetime, and battery lifetime is one of the major problems and the energy consumption can play a significant rule for the transmission of data in the SDN. Therefore, in this article, particle swarm optimization (PSO) based CGSR (cluster‐head gateway switch routing protocol) algorithm with fuzzy rules is proposed to increase the network lifetime of battery powered mobile nodes by reducing the energy consumptions of each node in software‐defined MANET. In this proposed method, a routing method that can permit various mobile nodes with low battery power to transmits the data from source node to base station. We design a PSO based CGSR routing protocol by selecting the routing mobile nodes using fuzzy rules for packet transmission. In CGSR process, the formation of cluster and selection of cluster head is executed depending on the particle swarm optimization method. This proposed routing protocol can be used to enhance the battery lifetime by extension of the network lifetime with numerical analysis for efficient route node selection.
Autonomic dysfunction, cardio‐pulmonary exercise testing and masked heart failure with preserved ejection fraction in non‐severe chronic obstructive pulmonary disease

Published: February 2020

AbstractBackgroundAutonomic dysfunction (AD) and cardiopulmonary exercise testing (CPET) parameters have been associated with masked heart failure with preserved ejection fraction (HFpEF) in the general population. Their clinical significance for masked HFpEF in chronic obstructive pulmonary disease (COPD) is however elusive.AimThe aim of the study was to determine the prevalence, correlation and clinical significance of AD and CPET with masked HFpEF, in non‐severe COPD patients, complaining of exertional dyspnoea, without clinically overt cardio‐vascular (CV) comorbidities.Methods and resultsWe applied CPET and echocardiography in 68 COPD subjects. Echocardiography was performed before CPET and 1–2 min after peak exercise. Patients were divided into two groups: patients with and without masked HFpEF. Peak E/e′ – 15 was applied as a cut‐off. Chronotropic incompetence (CI) was assumed if both failure to reach the target heart rate (HR) on exercise and diminished heart rate reserve <80% occurred. Abnormal HR recovery (HRR) was taken if the decline is <12 beats within the first minute after exercise cessation. Univariate regression showed association between masked HFpEF, HRR, VO2, VO2 at AT, oxygen pulse and VE/VCO2 slope. The multivariate regression demonstrated HRR as the only independent predictor of masked HFpEF – (OR 10.28; 95% CI (3.55–29.80)).ConclusionAbnormal HRR is the only independent predictor of masked HFpEF in non‐severe COPD patients. Despite of being associated with masked HFpEF, the lower VO2, lower oxygen pulse, higher VE/VCO2 slope and lower exercise load seem to be the consequences, rather than the triggers for it.

AbstractObjectivesWe investigated sex‐based differences in eligibility for and outcomes after receipt of advanced heart failure (HF) therapies.BackgroundAlthough women are more likely to die from HF than men, registry data suggest that women are less likely to receive heart transplant (HT) or left ventricular assist device (LVAD) for largely unknown reasons.MethodsWe performed a single‐center retrospective cohort study of patients evaluated for advanced HF therapies from 2012 to 2016. Logistic regression was used to determine the association of sex with eligibility for HT/LVAD. Competing risks and Kaplan‐Meier analysis were used to examine survival.ResultsOf 569 patients (31% women) evaluated, 223 (39.2%) were listed for HT and 81 (14.2%) received destination (DT) LVAD. Women were less likely to be listed for HT (adjusted odds ratio [OR] 0.36, 95% confidence interval [CI] 0.21‐0.61; P < .0001), based on allosensitization (P < .0001) and obesity (P = .02). Women were more likely to receive DT LVAD (adjusted OR 2.29, 95% CI 1.23‐4.29; P = .01). Survival was similar between men and women regardless of whether they received HT and DT LVAD or were ineligible for therapy.ConclusionWomen are less likely to be HT candidates, but more likely to receive DT LVAD.

Learning for and realising curriculum aspirations through schools as learning organisations
Authors: Sinnema Claire , Stoll Louise 
Published: February 2020

AbstractHow can schools as learning organisations support the realisation of a new curriculum's aspirations? This article describes four common and interrelated challenges—depth, spread, reach, and pace—associated with enacting a new curriculum. It then argues that curriculum capital represented by schools and practitioners that address these challenges and meet associated learning demands—commitment, knowledge, understanding and capability—is essential to ensure that curriculum aspirations are realised. We propose that schools that are learning organisations create the kinds of conditions necessary for responding to the challenges and learning demands. In such schools the considerable individual, collaborative and collective learning needed at many levels is recognised. We highlight how each of the four challenges might be addressed by seven dimensions and four transversals of schools as learning organisations, while recognising that task will be more feasible in systems that are also learning and providing supportive conditions.

AbstractObjectiveTo determine if closed‐loop optogenetic seizure intervention, previously shown to reduce seizure duration in a well‐established mouse model chronic temporal lobe epilepsy (TLE), also improves the associated comorbidity of impaired spatial memory.MethodsMice with chronic, spontaneous seizures in the unilateral intrahippocampal kainic acid model of TLE, expressing channelrhodopsin in parvalbumin‐expressing interneurons, were implanted with optical fibers and electrodes, and tested for response to closed‐loop light intervention of seizures. Animals that responded to closed‐loop optogenetic curtailment of seizures were tested in the object location memory test and then given closed‐loop optogenetic intervention on all detected seizures for 2 weeks. Following this, they were tested with a second object location memory test, with different objects and contexts than used previously, to assess if seizure suppression can improve deficits in spatial memory.ResultsAnimals that received closed‐loop optogenetic intervention performed significantly better in the second object location memory test compared to the first test. Epileptic controls with no intervention showed stable frequency and duration of seizures, as well as stable spatial memory deficits, for several months after the precipitating insult.SignificanceMany currently available treatments for epilepsy target seizures but not the associated comorbidities, therefore there is a need to investigate new potential therapies that may be able to improve both seizure burden and associated comorbidities of epilepsy. In this study, we showed that optogenetic intervention may be able to both shorten seizure duration and improve cognitive outcomes of spatial memory.

AbstractSolar steam generation has been considered as an effective way to solve the shortage of freshwater resources. In this paper, we have designed an interfacial evaporation device for efficient solar steam generation based on near infrared (NIR)‐absorbing lanthanum hexaboride (LaB6) nanoparticles and melamine sponge (MS) as the skeleton. LaB6 nanoparticles as a photothermal conversion material can absorb the NIR light and convert it into heat. Due to the porous 3D network and better hydrophilicity of MS, it can act as a substrate to support the LaB6 dispersed on the surface and transport the water by the capillary force. The evaporation rate of 1.13 kg m−2 h−1 and photothermal conversion efficiency of 60.7% under 1 kW m−2 solar illumination were achieved. Moreover, LaB6‐MS photothermal conversion device (LaB6‐MS PTCD), with excellent chemical stability could purify different water sources such as simulated seawater, strong acid, strong alkaline, and dyed methylene blue solution, exhibiting promising application in highly efficient solar energy‐driven seawater desalination and wastewater purification.

AbstractBackgroundResting energy expenditure (REE) estimates are often needed in young people and can be predicted using prediction equations based on body weight. However, these equations may perform poorly in those who are obese and overweight. The aim of this systematic review was to identify equations based on simple anthropometric and demographic variables that provide the most accurate and precise estimates of REE in healthy obese and overweight young people.MethodsSystematic searches for relevant studies in healthy obese and overweight young people aged ≤18 years were undertaken using PubMed, Scopus, Cinahl, OpenGrey and Cochrane Library (completed January 2018). Search terms included metabolism, calorimetry, obesity and prediction equation. Data extraction, study appraisal and synthesis followed PRISMA guidelines.ResultsFrom 390 screened titles, 13 studies met inclusion criteria. The most accurate REE predictions (least biased) were provided by Schofield equations [+0.8% (3–18 years); 0% (11–18 years); +1.1% (3–10 years)]. The most precise REE estimations (percentage of predictions ± 10% of measured) for 11–18 years were provided by Mifflin equations (62%) and, for 7–18 years, by the equations of Schmelzle (57%), Henry (56%) and Harris Benedict (54%). Precision of Schofield predictions was 43% in both age groups. No accuracy data were available for those <3 years or for precision for those <7 years.ConclusionsNo single equation provided accurate and precise REE estimations in this population. Schofield equations provided the most accurate REE predictions so are useful for groups. Mifflin equations provided the most precise estimates for individuals aged 11–18 years but tended to underestimate REE.
