The Role of Identity Integration in Enhancing Creativity Among Mixed‐Race Individuals
Authors: Tendayi Viki G. , Williams May Liang J. 
Published: December 2013

AbstractIdentity integration among bicultural individuals refers to the perception that their two cultural identities are compatible. Previous research has shown that identity integration is likely to lead to enhanced creativity. However, this research was conducted among first‐ and second‐generation immigrants, but not among mixed‐race individuals. The current research examined identity integration and creativity among mixed‐race individuals. We also explored the role of integrated identity experiences at home. We found that identity integration was related to increases in creativity; and this was partly mediated via integrated identity experiences at home. Our findings suggest that positive bicultural experiences at home may create a context for the individual to integrate their biracial identities; and this is ultimately beneficial for creativity.
A multiscale mass scaling approach for explicit time integration using proper orthogonal decomposition
Authors: de Frías G. J. , Aquino W. , Pierson K. H. , Heinstein M. W. , Spencer B. W. 
Published: December 2013

SUMMARYOne of the main computational issues with explicit dynamics simulations is the significant reduction of the critical time step as the spatial resolution of the finite element mesh increases. In this work, a selective mass scaling approach is presented that can significantly reduce the computational cost in explicit dynamic simulations, while maintaining accuracy. The proposed method is based on a multiscale decomposition approach that separates the dynamics of the system into low (coarse scales) and high frequencies (fine scales). Here, the critical time step is increased by selectively applying mass scaling on the fine scale component only. In problems where the response is dominated by the coarse (low frequency) scales, significant increases in the stable time step can be realized. In this work, we use the proper orthogonal decomposition (POD) method to build the coarse scale space. The main idea behind POD is to obtain an optimal low‐dimensional orthogonal basis for representing an ensemble of high‐dimensional data. In our proposed method, the POD space is generated with snapshots of the solution obtained from early times of the full‐scale simulation. The example problems addressed in this work show significant improvements in computational time, without heavily compromising the accuracy of the results. Copyright © 2013 John Wiley & Sons, Ltd.
Bird Bone Remains from the 11th and 12th Centuries Settlement of Piatra Frecatei (Dobrudja, Romania) in the Context of Early Medieval Sites in Southeast Romania
Authors: Gál E. , Stanc S. M. 
Published: December 2013

ABSTRACTIn this paper, the avian bones identified from the 11th and 12th centuries settlement of Piatra Frecatei in Dobrudja (Southeast Romania) are presented. The results are put in context with data from other two coeval sites in the region. Among the 86 bird bones representing 3.7% of the total animal bone assemblage, domestic hen was the most frequent species by 61 bones (71%) and 13 specimens (59.3%). The wild species include birds that live in the aquatic environment evidencing that fowling took place in the vicinity of site, and most probably was connected to fishing.

ObjectiveHepatic overexpression of sulfatase‐2 (SULF2), a heparan sulfate remodeling enzyme, strongly contributes to high triglyceride (TG) levels in obese, type 2 diabetic (T2DM) db/db mice. Nevertheless, data in humans are lacking. Here, the association of human hepatic SULF2 expression and SULF2 gene variants with TG metabolism in patients with obesity and/or T2DM was investigated.MethodsLiver biopsies from 121 obese subjects were analyzed for relations between hepatic SULF2 mRNA levels and plasma TG. Associations between seven SULF2 tagSNPs and TG levels were assessed in 210 obese T2DM subjects with dyslipidemia. Replication of positive findings was performed in 1,316 independent obese T2DM patients. Postprandial TRL clearance was evaluated in 29 obese T2DM subjects stratified by SULF2 genotype.ResultsLiver SULF2 expression was significantly associated with fasting plasma TG (r = 0.271; P = 0.003) in obese subjects. The SULF2 rs2281279(A>G) SNP was reproducibly associated with lower fasting plasma TG levels in obese T2DM subjects (P < 0.05). Carriership of the minor G allele was associated with lower levels of postprandial plasma TG (P < 0.05) and retinyl esters levels (P < 0.001).ConclusionsThese findings implicate SULF2 as potential therapeutic target in the atherogenic dyslipidemia of obesity and T2DM.

ABSTRACTObjectiveTo gain a better understanding of healthcare professionals' practice and attitudes regarding prenatal β‐thalassemia carrier screening in Australia.MethodQualitative study with semi‐structured interviews of healthcare professionals (obstetricians, general practitioners, midwives, genetic counselors, and hematologists) involved in prenatal thalassemia carrier screening in public and private practice.ResultsTwenty‐three healthcare providers were interviewed and several themes emerged. Participants described and acknowledged inconsistencies in the β‐thalassemia screening processes, such as variability in ordering the tests, communicating the diagnosis, and action taken after diagnosis. They indicated a preference for more structure and valued the importance of screening guidelines but many of those involved in ordering the screening test were unaware of their availability. These healthcare professionals recognized they lacked knowledge regarding the screening process, and many had not undertaken education activities in this area in recent times. There were mixed views about the consent process, particularly at which stage this should be obtained, and what information is provided.Conclusionsβ‐thalassemia screening in Victoria occurs with apparent lack of awareness of guidelines and an acknowledged preference for a more systematic process and educational support. Informed consent was not considered an important component of this screening process. © 2013 John Wiley & Sons, Ltd.

Published: December 2013

AbstractNew amphiphilic hyperbranched polymers possessing hydrophobic skeletons and hydrophilic terminal groups have been prepared and characterized. The synthetic strategy involved the formation of a new stable matrix with aromatic units within a carbosilane backbone, as well as the use of a classical polycarbosilane matrix. Both of them with allyl groups on the surface have narrow polydispersity values. Molecular weight and polydispersity of the hyperbranched polymers were obtained using gel permeation chromatography with multi‐angle light scattering, and determination of the average number of functional groups present on the surface was achieved using 1H NMR spectroscopy. The introduction of ionic groups was carried out via thiol–ene reactions with various thiol derivatives. The thermal properties of the polymers were also analysed using differential scanning calorimetry and zeta potential measurements. © 2013 Society of Chemical Industry
The interfacial effect of TiO2–Ag core–shell micro‐/nanowires on poly(arylene ether nitrile)
Authors: Huang Xu , Feng Mengna , Liu Xiaobo 
Published: December 2013

AbstractNovel TiO2–Ag core–shell micro‐/nanowires (TiO2 shell coating on Ag core) have been successfully prepared via a solvent–thermal method. Energy dispersive spectroscopy and X‐ray diffraction analyses revealed that the micro‐/nanowires were composed of Ag, Ti and O elements, and Ag was face‐centered cubic whereas TiO2 was mainly amorphous. Interestingly, scanning electron microscopy (SEM) and transmission electron microscopy results showed that most of the TiO2 bristles were perpendicular to and uniformly studded on the surface of the Ag cores. Subsequently, TiO2–Ag/poly(arylene ether nitrile) (PEN) composite films were prepared via a solution‐casting method in order to investigate the effect of TiO2–Ag on the PEN matrix. SEM images showed that there was good interfacial adhesion between fillers and PEN matrix owing to the special bristle‐like structure. Thermal analysis results showed that the TiO2–Ag/PEN composite films possessed excellent thermal properties endowed by the PEN matrix. The dielectric constant of the composite films increased to 9.3 at 100 Hz when the TiO2–Ag loading reached 40 wt%. Rheology measurements revealed that the network formed by TiO2–Ag was sensitive to shear stress and nearly time independent. © 2013 Society of Chemical Industry
Synthesis and characterization of ABA‐type triblock copolymers derived from polyimide and poly(2‐methyl‐2‐adamantyl methacrylate)

Published: December 2013

AbstractABA‐type triblock copolymers derived from 4,4‐(hexafluoroisopropylidene)diphthalic anhydride‐2,3,5,6‐tetramethyl‐1,4‐phenylenediamine and 2‐methyl‐2‐adamantyl methacrylate (2‐MAdMA) were synthesized via atom transfer radical polymerization. The component ratios of polyimide (PI) and poly(2‐MAdMA) (PMAdMA) were about 8/2, 6/4 and 3/7, as determined using 1H NMR spectroscopy and thermogravimetric analysis (TGA). The film structure of the triblock copolymers was dependent on the PI structure. Hydrophobicity increased as the component ratio of PMAdMA increased. Based on TGA, three‐step decomposition behaviors of all triblock copolymers derived from PI and PMAdMA in nitrogen and air atmosphere were observed. The gas permeability of the triblock copolymers was lower than that of PI. This finding can be attributed to the decrease in fractional free volume by the adamantane component and the decrease in permeability of the triblock copolymers compared with PI. The dielectric constant of the triblock copolymers was lower than that of PI. The dielectric constant was dependent on molar volume and molar porlarizability, and the dielectric constant derived from the symmetric structure of adamantane was reduced. The ABA‐type triblock copolymers derived from PI and PMAdMA can be considered as new polymer materials with high hydrophobicity, high H2/CO2 selectivity and low dielectric constant. © 2013 Society of Chemical Industry
Introduction to Special Issue: A Review of the International Classification of Functioning, Disability and Health and Physical Therapy over the Years
Authors: Escorpizo Reuben , Bemis‐Dougherty Anita 
Published: December 2013

AbstractBackground and PurposeThe International Classification of Functioning, Disability and Health (ICF) of the World Health Organization was developed as a common framework to understand health and to describe the impact of health condition on functioning. The purpose of this paper is to summarize the literature on the use of the ICF in physical therapy practice and research.MethodsWe performed a scoping‐narrative review and searched for relevant English language articles from 2001 to 2012 in multiple databases that included MEDLINE, PsycINFO, PubMed and Physiotherapy Evidence Database. Our keywords for the search consisted of [‘physical therapy’ OR ‘physiotherapy’] AND [‘ICF’]. All types of articles were considered.ResultsWe found 268 articles; out of which, 79 were reviewed. The years with most publications were 2011 (n = 16), 2008 (n = 15) and 2010 and 2012 (both with n = 13). Publications mostly came from the United States with 27% of the articles. The journal Physical Therapy leads with almost a third of ICF‐related physical therapy publications. The ICF has been mostly used in studies of musculoskeletal and neuromuscular conditions. We found a wide array of application of the ICF in research, clinical practice and teaching (classroom and clinical education). Emerging topics included using the ICF in resource allocation and prevention and wellness.ConclusionThe use of the ICF in physical therapy practice and research is promising and continues to evolve. With recent developments in ICF‐based measurement and integration in assessment tools for use in the clinics, research and teaching, the need to show the added value of using the ICF in practice and research remains.

Published: December 2013

Variable selection in linear models is essential for improved inference and interpretation, an activity which has become even more critical for high dimensional data. In this article, we provide a selective review of some classical methods including Akaike information criterion, Bayesian information criterion, Mallow's Cpand risk inflation criterion, as well as regularization methods including Lasso, bridge regression, smoothly clipped absolute deviation, minimax concave penalty, adaptive Lasso, elastic‐net, and group Lasso. We discuss how to select the penalty parameters. We also provide a review for some screening procedures for ultra high dimensions.WIREs Comput Stat2014, 6:1–9. doi: 10.1002/wics.1284This article is categorized under:Statistical Models > Linear ModelsStatistical Learning and Exploratory Methods of the Data Sciences > Modeling MethodsStatistical Models > Model Selection
Removing barred owls from local areas: Techniques and feasibility
Authors: Diller Lowell V. , Dumbacher John P. , Bosch Raymond P. , Bown Robin R. , Gutiérrez R. J. 
Published: December 2013

AbstractThe barred owl (Strix varia) has invaded the range of the northern spotted owl (S. occidentalis caurina) over the past century. The Northern Spotted Owl Recovery Plan recommended removal experiments to assess both the effect of barred owls on spotted owls and the feasibility of initiating some form of barred owl control to enhance recovery of the northern spotted owl. Concern has been raised that such experiments will be neither feasible nor cost‐effective. To assess these and other concerns, we conducted lethal removal of barred owls within 3 areas totaling 85,205 ha in northern California, USA. We collected 73 of 81 territorial barred owls detected from 2009 to 2012 during 122 field visits. It took an average of 2 hr 23 min to collect each barred owl from the time of arrival at a site to the time a collected bird was completely processed for field data. Most barred owls were collected within one‐half hour of arrival at a site. Lethal removal of barred owls was rapid, technically feasible, and cost‐effective. We provide recommendations for techniques we found to be effective. © 2013 The Wildlife Society.

ObjectivesThis paper aims to show how effective teamworking can be achieved in Community Mental Health Teams (CMHTs), in the context of recovery-focused care.MethodsA narrative review of various governmental policy documents and selected papers relevant to teamworking and recovery-focused care within mental health services, in an Irish context.FindingsEffective teamworking within CMHTs is a prerequisite to the provision of quality, recovery-focused care. It requires the management of various environmental (e.g. adopting a ‘recovery’ model of mental health), structural (e.g. sharing of responsibilities and capabilities) and process (e.g. utilising a clear referral pathway) factors that influence teamworking, as CMHTs develop over time.ConclusionsCompletion by CMHT members of teamworking and other evaluative measures can assist teams in highlighting potential interventions that may improve recovery-focused team functioning and effectiveness.

For k transcendental over the prime field we extend a result in [1] showing that and Shv1 have equivalent bounded derived categories.
Approximate modelling of the leftward flow and morphogen transport in the embryonic node by specifying vorticity at the ciliated surface

Published: December 2013

AbstractIn this paper, we have developed an approximate method for modelling the flow of embryonic fluid in a ventral node. We simplified the problem as flow in a two-dimensional cavity; the effect of rotating cilia was modelled by specifying a constant vorticity at the edge of the ciliated layer. We also developed an approximate solution for morphogen transport in the nodal pit. The solutions were obtained utilizing the proper generalized decomposition (PGD) method. We compared our approximate solutions with the results of numerical simulation of flow caused by the rotation of 81 cilia, and obtained reasonable agreement in most of the flow domain. We discuss locations where agreement is less accurate. The obtained semi-analytical solutions simplify the analysis of flow and morphogen distribution in a nodal pit.
Flow-induced segregation in confined multicomponent suspensions: effects of particle size and rigidity
Authors: Kumar Amit , Henríquez Rivera Rafael G. , Graham Michael D. 
Published: December 2013

AbstractThe effects of particle size and rigidity on segregation behaviour in confined simple shear flow of binary suspensions of fluid-filled elastic capsules are investigated in a model system that resembles blood. We study this problem with direct simulations as well as with a master equation model that incorporates two key sources of wall-normal particle transport: wall-induced migration and hydrodynamic pair collisions. The simulation results indicate that, in a mixture of large and small particles with equal capillary numbers, the small particles marginate, while the large particles antimarginate in their respective dilute suspensions. Here margination refers to localization of particles near walls, while antimargination refers to the opposite. In a mixture of particles with equal size and unequal capillary number, the stiffer particles marginate while the flexible particles antimarginate. The master equation model traces the origins of the segregation behaviour to the size and rigidity dependence of the wall-induced migration velocity and of the cross-stream particle displacements in various types of collisions. In particular, segregation by rigidity, especially at low volume fractions, is driven in large part by heterogeneous collisions, in which the stiff particle undergoes larger displacement. In contrast, segregation by size is driven mostly by the larger wall-induced migration velocity of larger particles. Additionally, a non-local drift-diffusion equation is derived from the master equation model, which provides further insights into the segregation behaviour.
Experimental investigation of transitional flow in a toroidal pipe
Authors: Kühnen J. , Holzner M. , Hof B. , Kuhlmann H. C. 
Published: December 2013

AbstractThe flow instability and further transition to turbulence in a toroidal pipe (torus) with curvature ratio (tube-to-coiling diameter) 0.049 is investigated experimentally. The flow inside the toroidal pipe is driven by a steel sphere fitted to the inner pipe diameter. The sphere is moved with constant azimuthal velocity from outside the torus by a moving magnet. The experiment is designed to investigate curved pipe flow by optical measurement techniques. Using stereoscopic particle image velocimetry, laser Doppler velocimetry and pressure drop measurements, the flow is measured for Reynolds numbers ranging from 1000 to 15 000. Time- and space-resolved velocity fields are obtained and analysed. The steady axisymmetric basic flow is strongly influenced by centrifugal effects. On an increase of the Reynolds number we find a sequence of bifurcations. For $\mathit{Re}= 4075\pm 2\hspace{0.167em} \% $ a supercritical bifurcation to an oscillatory flow is found in which waves travel in the streamwise direction with a phase velocity slightly faster than the mean flow. The oscillatory flow is superseded by a presumably quasi-periodic flow at a further increase of the Reynolds number before turbulence sets in. The results are found to be compatible, in general, with earlier experimental and numerical investigations on transition to turbulence in helical and curved pipes. However, important aspects of the bifurcation scenario differ considerably.
Kelvin wake pattern at large Froude numbers
Authors: Darmon Alexandre , Benzaquen Michael , Raphaël Elie 
Published: December 2013

AbstractGravity waves generated by an object moving at constant speed at the water surface form a specific pattern commonly known as the Kelvin wake. It was proved by Lord Kelvin that such a wake is delimited by a constant angle${\simeq }19. 4{7}^{\circ } $. However a recent study by Rabaud and Moisy based on the observation of airborne images showed that the wake angle seems to decrease as the Froude number$Fr$increases, scaling as$F{r}^{- 1} $for large Froude numbers. To explain such observations they make the strong hypothesis that an object of size$b$cannot generate wavelengths larger than$b$. Without the need of such an assumption and modelling the moving object by an axisymmetric pressure field, we analytically show that the angle corresponding to the maximum amplitude of the waves scales as$F{r}^{- 1} $for large Froude numbers, whereas the angle delimiting the wake region outside which the surface is essentially flat remains constant and equal to the Kelvin angle for all$Fr$.
Two-dimensional streaming flows driven by sessile semicylindrical microbubbles
Authors: Rallabandi Bhargav , Wang Cheng , Hilgenfeldt Sascha 
Published: December 2013

AbstractSteady streaming flow from oscillating sessile bubbles at walls is the centrepiece of many microstreaming experiments. A complete asymptotic theory of the flow is developed, requiring only the oscillatory driving frequency and material parameters as input, and properly accounting for bubble and wall boundary conditions. It is shown that mixed-mode streaming of neighbouring bubble oscillation modes is responsible for the robustness of the generic ‘fountain’ vortex pair flow pattern, and that the pattern reverses for high frequencies when wall-induced streaming becomes dominant. The far-field flow and its dependence on control parameters are in agreement with experimental data and can be understood considering just a few asymptotic coefficients.
