COMPATIBILITY AND ATTAINABILITY OF MATRICES OF CORRELATION-BASED MEASURES OF CONCORDANCE
Authors: Hofert Marius , Koike Takaaki 
Published: May 2019

AbstractMeasures of concordance have been widely used in insurance and risk management to summarize nonlinear dependence among risks modeled by random variables, which Pearson’s correlation coefficient cannot capture. However, popular measures of concordance, such as Spearman’s rho and Blomqvist’s beta, appear as classical correlations of transformed random variables. We characterize a whole class of such concordance measures arising from correlations of transformed random variables, which includes Spearman’s rho, Blomqvist’s beta and van der Waerden’s coefficient as special cases. Compatibility and attainability of square matrices with entries given by such measures are studied—that is, whether a given square matrix of such measures of concordance can be realized for some random vector and how such a random vector can be constructed. Compatibility and attainability of block matrices and hierarchical matrices are also studied due to their practical importance in insurance and risk management. In particular, a subclass of attainable block Spearman’s rho matrices is proposed to compensate for the drawback that Spearman’s rho matrices are in general not attainable for dimensions larger than three. Another result concerns a novel analytical form of the Cholesky factor of block matrices which allows one, for example, to construct random vectors with given block matrices of van der Waerden’s coefficient.
Parental Involvement in Supporting Their Children with Special Educational Needs at School and Home in Bhutan

Published: May 2019

AbstractThis paper reports the findings from a study investigating Bhutanese parents’ involvement in supporting their children with special educational needs (SEN) in schooling. The interaction between the parents themselves in supporting each other was also explored. Individual interviews were conducted with 26 parents (13 fathers and 13 mothers) of children with either full inclusion or partial inclusion in 3 schools located in 3 regions (urban, semi-urban, and rural) and analysed using manual thematic coding and Leximancer text mining software. Of Epstein’s (1987) 6 types of parental involvement activities in education, these parents reported their actions to be parenting, volunteering in schools, supporting learning and development at home, and collaborating with the community. The minimal interaction among the parents was mostly between the stay-in-school urban mothers who had consistent but impromptu and informal interactions. The implications of this study inform the need for schools to respond to policy and to actively engage parents, and for education programs and support groups to be set up to strengthen parental involvement in the education of children with SEN in Bhutan.

Published: May 2019

ABSTRACTRadiocarbon (14C) analysis was performed on Japanese cedar (Cryptomeria japonica) tree rings from Koriyama, Fukushima prefecture. Our primary aim was to detect any 14C release from the Fukushima Dai-ichi nuclear power plant accident on 11 March 2011. We also completed and assessed the 14C level in Japanese tree rings for the period of 1990–2014 because of the lack of environmental 14C results in the Japanese island that time. For this reason, we used a trajectory model to investigate the air mass forward and backward trajectories at the area of the power plant and sampling site. The modeling data show that the air masses mainly moved to the Pacific Ocean, both during March 2011 and during the growing season (March–September). During the period 1990–2014 there was no significant 14C excess in any of the samples, but there was a detectable Suess effect in almost every tree ring sample. The average fossil contribution was 0.83 ± 0.01% and the calculated anthropogenic component ratio, the 14C excess varied between +0.5 and –1.6%. The Δ14C value decreased from 150.0‰ to 9.5‰ from 1990–2014, which follows the decline of the 14C bomb peak, in addition to any detectable Suess effect.
The U.S. Embassy Move to Jerusalem: Mixed Messages and Mixed Blessings for Israel?
Authors: Dumper Mick 
Published: May 2019

AbstractThe U.S. decision in December 2017 to move its embassy in Israel from Tel Aviv to Jerusalem recognizes the latter as the capital of Israel. While violating several UN resolutions and international law, it has in the short-term impacted the negotiations between the Palestinian Liberation Organization (PLO) and Israel. In the longer term we can see that the impact of the decision is also more complex and nuanced. There are three main areas which suggest this to be the case: First, the lack of clarity over the decision itself; second, the varying degrees of sovereignty exercised by Israel in different parts of Jerusalem due to the city's long and religiously diverse history; and thirdly, the contradictions inherent in imposing a nationalist ideology upon a cosmopolitan and heterodox city.
Manly Civilization in China: Harry R. Caldwell, the ‘Blue Tiger’, and the American Museum of Natural History
Authors: CHAN YING-KIT 
Published: May 2019

AbstractThis article examines the transplantation of America's ‘manly’ civilization to 1920s Fujian, China, through the experiences of Harry R. Caldwell (1876–1970), a Methodist missionary whose hunting was central to his social evangelism. With his rifle, Caldwell protected Chinese villagers from man-eating tigers, taught them how to hunt tigers effectively, and enabled them to reconceptualize their relationships with tigers and nature. By engaging the American Museum of Natural History in his specimen collection and hunt for the mythical ‘Blue Tiger’, Caldwell introduced an economy of natural expeditions to the villagers who were hired to support the hunt. This article argues that Caldwell's experiences as both a missionary and a hunter in Fujian was an extension, or negotiation, of his rugged masculinity, which was fostered in his Tennessee home town. He identified as both a Christian and a hunter, and he did not see these parts of himself as distinct. A comparison between Caldwell and his contemporary, the British naturalist Arthur de Carle Sowerby (1885–1954), accentuates America's rugged masculinity by suggesting different national approaches to hunting and the growing professionalization of the naturalist.
Robust Semantic Mapping in Challenging Environments
Authors: Cheng Jiyu , Sun Yuxiang , Meng Max Q.-H. 
Published: May 2019

SummaryVisual simultaneous localization and mapping (visual SLAM) has been well developed in recent decades. To facilitate tasks such as path planning and exploration, traditional visual SLAM systems usually provide mobile robots with the geometric map, which overlooks the semantic information. To address this problem, inspired by the recent success of the deep neural network, we combine it with the visual SLAM system to conduct semantic mapping. Both the geometric and semantic information will be projected into the 3D space for generating a 3D semantic map. We also use an optical-flow-based method to deal with the moving objects such that our method is capable of working robustly in dynamic environments. We have performed our experiments in the public TUM dataset and our recorded office dataset. Experimental results demonstrate the feasibility and impressive performance of the proposed method.
Three-Dimensional Reconstruction Based on Visual SLAM of Mobile Robot in Search and Rescue Disaster Scenarios

Published: May 2019

SummaryConventional simultaneous localization and mapping (SLAM) has concentrated on two-dimensional (2D) map building. To adapt it to urgent search and rescue (SAR) environments, it is necessary to combine the fast and simple global 2D SLAM and three-dimensional (3D) objects of interest (OOIs) local sub-maps. The main novelty of the present work is a method for 3D OOI reconstruction based on a 2D map, thereby retaining the fast performances of the latter. A theory is established that is adapted to a SAR environment, including the object identification, exploration area coverage (AC), and loop closure detection of revisited spots. Proposed for the first is image optical flow calculation with a 2D/3D fusion method and RGB-D (red, green, blue + depth) transformation based on Joblove–Greenberg mathematics and OpenCV processing. The mathematical theories of optical flow calculation and wavelet transformation are used for the first time to solve the robotic SAR SLAM problem. The present contributions indicate two aspects: (i) mobile robots depend on planar distance estimation to build 2D maps quickly and to provide SAR exploration AC; (ii) 3D OOIs are reconstructed using the proposed innovative methods of RGB-D iterative closest points (RGB-ICPs) and 2D/3D principle of wavelet transformation. Different mobile robots are used to conduct indoor and outdoor SAR SLAM. Both the SLAM and the SAR OOIs detection are implemented by simulations and ground-truth experiments, which provide strong evidence for the proposed 2D/3D reconstruction SAR SLAM approaches adapted to post-disaster environments.
A model for tidal motion and level in the Tay Estuary
Authors: Gunn D. J. , Yenigun O. 
Published: May 2019

SynopsisA new mathematical model has been constructed for tidal motion and level in the Tay Estuary. The model is based upon the two-dimensional vertically integrated equations of motion and gives two-dimensional vector velocities and levels from the rail bridge to the Bar, about 5 km east of Buddon Ness. The extent of the model outside the mouth of the Tay is 3 km north of Buddon Ness and 7 km south. The equations of motion are expressed in the form of central differences in space and solved explicitly in time using the Local Integral Method. The emergence and submergence of drying zones in the estuary are calculated during the tidal cycle. A representation of the hydrodynamic resistance of the road bridge was included in the model.The boundary conditions for the model were based upon estimates of river flows at the western entrance and tidal levels at the eastern, northern and southern boundaries. Boundary conditions at the eastern end of the model presented considerable complexities because of the presence of an amphidromic system to the south of the Norwegian coast. The final solution adopted was to choose tidal levels along the easterly boundaries to give velocities in the outer estuary that agreed with available tidal atlases of the region.Velocities and levels at intervals of 250 m for the period of a tide show the prevalent shoaling conditions over the estuary combined during certain periods with conditions of high velocity, giving very difficult approaches to the River Tay.
Monitoring the effects of the disposal at sea of Lothian Region sewage sludge
Authors: Moore D. C. , Davies I. M. 
Published: May 2019

SynopsisUntil the late 1970s Edinburgh and the surrounding areas employed a series of relatively short sea outfalls to dispose of sewage to tidal waters. A centralised sewage treatment facility was provided in 1977, with disposal of liquid effluent by long sea outfall. The residual wet solids are dumped at two sites in the North Sea off the Firth of Forth. The sites, one near Bell Rock (56 25N 02 10W) and one ten miles north of St Abb's Head (56 04·5N 02 07·25W) are used on a rotational basis. The macrofauna at both sites shows a normal polychaete-dominated community exhibiting the normal low number/high diversity characteristics of many unimpacted communities in the North Sea. In general, seasonal differences in mean concentrations of lead, copper and zinc in sediments were small and within the limits of statistical variation. The concentrations of mercury and cadmium were mainly low and close to the detection limits of the analytical methods employed. The monitoring data from Bell Rock and St Abb's Head demonstrate that the dumping operation has had little effect on the benthic environment and that the macrobenthos showed no signs of stress due to the addition of sewage sludge.
The seals of the Forth, Scotland
Authors: Harwood J. , Wyile O. Geraldine 
Published: May 2019

SynopsisAlthough common seals (Phoca vitulina L.) do occur in the Firth of Forth, the grey seal (Halichoerus grypus Fab.) is by far the most abundant species in the area. Some pups are born along the north shore of the outer firth but the vast majority are born on the Isle of May. This colony has increased in size from less than twenty-five pups in 1975 to more than 900 in 1986. Studies using conventional and radio tags indicate that many of the seals at the Isle of May originally came from the colony at the Farne Islands, off the Northumberland coast. Information from the Fame Islands population is used to predict future changes at the Isle of May. If current trends continue, more than 2000 pups could be born each year by the end of the century. However, it seems unlikely that this will occur. Management methods for controlling habitat damage are discussed.
A Lawyers’ View of Special Education: Past, Present and Future
Authors: Hayes Robert , Macalpine Susan 
Published: May 2019

Richard Nixon was moved to exclaim that: “writing is the toughest thing I have ever done”. We feel similarly daunted at the prospect of writing about the legal system’s miserly treatment of children in need of special schooling. But at least we will be saved in our endeavours from the temptation of the lawyers’ notorious prolixity. For the story is a short and simple one. It will be very difficult to make it long and complicated.There is no doubt that a great deal has been achieved in special education over the past few years. We can only speak of the Sydney and Melbourne metropolitan areas. But it is probably true to say that in them, most children with disabilities can be reasonably sure of receiving a high quality education in an educational setting which is well provided with resources. But this is because it is currently Government policy in these States to provide disabled children with a place in a mainstream school, where this is feasible.
Eating frequency and weight status in Portuguese children aged 3–9 years: results from the cross-sectional National Food, Nutrition and Physical Activity Survey 2015–2016
Authors: Vilela Sofia , Correia Daniela , Severo Milton , Oliveira Andreia , Torres Duarte , Lopes Carla ,   and the IAN-AF Consortium
Published: May 2019

AbstractObjective:To evaluate daily eating frequency (main meals and snacks) in relation to weight status in children aged 3–9 years, representative of the Portuguese population.Design:Cross-sectional study. Dietary intake was estimated as the mean of two non-consecutive days of food diaries, followed by face-to-face interviews. Weight and height were measured by trained observers. Eating occasions (EO) were defined by the children’s caregiver; an EO was considered separate if the time of consumption was different from other EO and it provided at least 209 kJ (50 kcal). Main meals defined as ‘breakfast’, ‘lunch’ and ‘dinner’ could be selected only once per day. The remaining EO were considered snacks. The association between eating frequency and overweight/obesity was evaluated through logistic regressions weighted for the population distribution.Setting:National Food, Nutrition and Physical Activity Survey of the Portuguese population, 2015–2016.Participants:Portuguese children aged 3–9 years with complete dietary data and anthropometric measurements (n 517).Results:Overall, the number of daily EO ranged from 3·5 to 11, and on average children had 5·7 daily EO. After adjustment for child’s sex, age and total energy intake, and considering only plausible energy intake reporters, having < 3 snacks/d was positively associated with being overweight/obese (OR = 1·98; 95 % CI 1·00, 3·90), compared with having ≥ 3 snacks/d.Conclusions:Lower daily frequency of EO was associated with increased odds of being overweight or obese in children. A higher eating frequency, maintaining the same energy intake, seems to contribute to a healthy body weight in children.

Published: May 2019

AbstractObjective:To use cognitive interviewing and pilot testing to develop a survey instrument feasible for administering in the food pantry setting to assess daily intake frequency from several major food groups and dietary correlates (e.g. fruit and vegetable barriers) – the FRESH Foods Survey.Design:New and existing survey items were adapted and refined following cognitive interviews. After piloting the survey with food pantry users in the USA, preliminary psychometric and construct validity analyses were performed.Setting:Three US food banks and accompanying food pantries in Atlanta, GA, San Diego, CA, and Buffalo, NY.Participants:Food pantry clients (n 246), mostly female (68 %), mean age 54·5 (sd 14·7) years.Results:Measures of dietary correlates performed well psychometrically: Cronbach’s α range 0·71–0·90, slope (α) parameter range 1·26–6·36, and threshold parameters (β) indicated variability in the ‘difficulty’ of the items. Additionally, all scales had only one eigenvalue above 1·0 (range 2·07–4·71), indicating unidimensionality. Average (median, Q1–Q3) daily intakes (times/d) across six dietary groups were: fruits and vegetables (2·87, 1·87–4·58); junk foods (1·16, 0·58–2·16); fast foods and similar entrées (1·45, 0·58–2·03); whole-grain foods (0·87, 0·58–1·71); sugar-sweetened beverages (0·58, 0·29–1·29); milk and milk alternatives (0·71, 0·29–1·29). Significant correlations between dietary groups and dietary correlates were largely in the directions expected based on the literature, giving initial indication of convergent and discriminant validity.Conclusions:The FRESH Foods Survey is efficient, tailored to food pantry populations, can be used to monitor dietary behaviours and may be useful to measure intervention impact.
Television food and beverage marketing to children in Costa Rica: current state and policy implications

Published: May 2019

AbstractObjective:To examine the frequency of television (TV) food and beverage advertisements (F&amp;B ads) to which children (4–11 years) are likely exposed and the nutrient profile of products advertised.Design:TV broadcasting between September and November 2016 was recorded (288 h of children’s programming; 288 h of family programming) resulting in 8980 advertisements, of which 1862 were F&amp;B ads. Of those, 1473 could be classified into one of the seventeen food groups, and into permitted/non-permitted according to the WHO-EU nutrient profile model. Persuasive marketing techniques used were also identified.Setting:TV programming was recorded for four weekdays and four weekend days, between 06.00 and 00.00 hours (576 total hours), for four channels (two national and two cable), in Costa Rica.Results:Mean (sd) number of F&amp;B ads/h was greater in cable than national channels (3·7 (0·4)v. 2·8 (0·4),P&lt; 0·05) and during children’s peak viewing hours (4·4 (0·4)v. 2·9 (0·3)). Of F&amp;B ads classified with WHO-EU nutrient profile model (n1473, 71·1 %), 91·1 % were non-permitted to be marketed to children. Categories most frequently advertised were ready-made/convenience foods (16 %), chocolates/confectionery/desserts (15 %), breakfast cereals (14 %), beverages (15 %), edible ices (9 %) and salty snacks (8 %). Non-permitted F&amp;B ads were more likely to use promotional characters, brand benefit claims, and nutrition and health claims than permitted F&amp;B ads.Conclusions:Children watching popular TV channels in Costa Rica are exposed to a high number of unhealthy F&amp;B ads daily. Our findings help justify the need for regulatory actions by national authorities.

AbstractObjective:Dietary guidelines are an essential policy tool for facilitating optimal dietary patterns and healthy eating behaviours. We report: (i) the methodological approach adopted for developing the National Dietary Guidelines of Greece (NDGGr) for Infants, Children and Adolescents; and (ii) the guidelines for children aged 1–18 years.Design:An evidence-based approach was employed to develop food-based recommendations according to the methodologies of the WHO, FAO and European Food Safety Authority. Physical activity recommendations were also compiled. Food education, healthy eating tips and suggestions were also provided.Setting:The NDGGr encompass food-based nutritional and physical activity recommendations for promoting healthy dietary patterns and eating behaviours and secondarily to serve as a helpful tool for the prevention of childhood overweight and obesity.Results:The NDGGr include food-based recommendations, food education and health promotion messages regarding: (i) fruits; (ii) vegetables; (iii) milk and dairy products; (iv) cereals; (v) red and white meat; (vi) fish and seafood; (vii) eggs; (viii) legumes; (ix) added lipids, olives, and nuts; (x) added sugars and salt; (xi) water and beverages, and (xii) physical activity. A Nutrition Wheel, consisting of the ten most pivotal key messages, was developed to enhance the adoption of optimal dietary patterns and a healthy lifestyle. The NDGGr additionally provide recommendations regarding the optimal frequency and serving sizes of main meals, based on the traditional Greek diet.Conclusions:As a policy tool for promoting healthy eating, the NDGGr have been disseminated in public schools across Greece.
Estimating Step Heights from Top-Down SEM Images

Published: May 2019

AbstractScanning electron microscopy (SEM) is one of the most common inspection methods in the semiconductor industry and in research labs. To extract the height of structures using SEM images, various techniques have been used, such as tilting a sample, or modifying the SEM tool with extra sources and/or detectors. However, none of these techniques focused on extraction of height information directly from top-down images. In this work, using Monte Carlo simulations, we studied the relation between step height and the emission of secondary electrons (SEs) resulting from exposure with primary electrons at different energies. It is found that part of the SE signal, when scanning over a step edge, is determined by the step height rather than the geometry of the step edge. We present a way to quantify this, arriving at a method to determine the height of structures from top-down SEM images. The method is demonstrated on three different samples using two different SEM tools, and atomic force microscopy is used to measure the step height of the samples. The results obtained are in qualitative agreement with the results from the Monte Carlo simulations.
