Proximate influences on female dispersal in white‐tailed deer
Authors: Lutz Clayton L. , Diefenbach Duane R. , Rosenberry Christopher S. 
Published: June 2016

ABSTRACTUltimate causes of animal dispersal have been hypothesized to benefit the dispersing individual because dispersal reduces competition for local resources, potential for inbreeding, and competition for breeding partners. However, proximate cues influence important features of dispersal behavior, including when dispersal occurs, how long it lasts, and direction, straightness, and distance of the dispersal path. Therefore, proximate cues that affect dispersal influence ecological processes (e.g., population dynamics, disease transmission, gene flow). We captured and radio‐marked 277 juvenile female white‐tailed deer (Odocoileus virginianus), of which 27 dispersed, to evaluate dispersal behavior and to determine proximate cues that may influence dispersal behavior. Female dispersal largely occurred at 1 year of age and coincided with the fawning season. Dispersal paths varied but generally were non‐linear and prolonged. Physical landscape features (i.e., roadways, rivers, residential areas) influenced dispersal path direction and where dispersal terminated. Additionally, forays outside of the natal range that did not result in dispersal occurred among 52% of global positioning system (GPS)‐collared deer (n = 25) during the dispersal period. Our results suggest intra‐specific social interactions and physical landscape features influence dispersal behavior in female deer. Female dispersal behavior, particularly the lack of directionality, the semi‐permeable nature of physical barriers, and the frequency of forays outside of the natal range, should be considered in regard to population management and controlling the spread of disease. © 2016 The Wildlife Society.

Objectives/HypothesisTo analyze whether there is correlation between branching patterns of anterior inferior cerebellar artery/posterior inferior cerebellar artery (AICA/PICA) in cerebellopontine angle (CPA) area, as demonstrated by three‐dimensional fast imaging employing steady‐state acquisition (3D FIESTA) magnetic resonance imaging (MRI) and 1) idiopathic sudden sensorineural hearing loss (ISSNHL) outcomes and 2) recovery of ISSNHL.Study DesignWe evaluated patients with idiopathic SSNHL for branching patterns of AICA/PICA in CPA area, as demonstrated by 3D FIESTA MRI.MethodsSixty‐eight patients with SSNHL (32 [47.1%] women; mean age 45.3 ± 14.6 [minimum–maximum: 18–77]) and 38 healthy volunteers [17 (44.7%) women; mean age 48.6 ± 14.0 (minimum–maximum: 26–81)] were included in this study. We evaluated patients for branching patterns and classified as type IA, IB, IIA, and IIB. Branching patterns were evaluated at the diseased side of the patients and both sides of the control group. Pretreatment and posttreatment audiological values were also studied.ResultsAICA/PICA branching patterns in control group versus study group in the affected side were: 26 (34.2%) versus 12 (17.6%) subjects had type IA; seven (9.2%) versus nine (13.2%) subjects had type IB; 31 (40.8%) versus 23 (33.8%) subjects had type IIA; and 12 (15.8) versus 24 (35.3%) subjects had type IIB branching patterns, respectively. Presence of vascular loops entering internal acoustic channel (type IIB branching pattern) was more prominent in the study group (P = 0.017). In addition, type IIB branching pattern was significantly associated with unresponsiveness to treatment (18 [75%] of 24 patients with type IIB were unresponsive and 14 [47.0%] of 30 patients with nontype IIB were unresponsive, P < 0.001).ConclusionType IIB branching pattern has been shown to be more common in patients with ISSNHL, and these patients come across with unresponsiveness to standard therapy more than the other branching types.Level of Evidence3b.

Improving Blood Compatibility of Polyethersulfone Hollow Fiber Membranes via Blending with Sulfonated Polyether Ether Ketone
Authors: Salimi Esmaeil , Ghaee Azadeh , Ismail Ahmad Fauzi 
Published: June 2016

Appropriate membrane for blood contacting applications requires hemocompatibility and high permeation flux; it should inhibit proteins or platelets adsorption and still possess high permeability. Aiming to improve the polyethersulfone (PES) hollow fiber membrane hemocompatibility, sulfonated polyether ether ketone (SPEEK) is self‐synthesized in the present research and added to PES in different ratios. Scanning electron microscopy images have revealed significant changes in PES membranes structure after addition of SPEEK, which can influence water permeation property of the membranes. Water contact angles of the membranes have reduced from 75° to 50° after addition of 4 wt% SPEEK. Influence of SPEEK addition on hemocompatibility of the PES membranes is evaluated via protein (bovine serum albumin) adsorption, platelet attachment, and coagulation time (APTT and TT) assays. Obtained results reveal that hemocompatibility of the modified hollow fiber membranes is enhanced as a result of emerging repulsive forces between negative charges on the membranes surface and negatively charge blood components.

Using Mechanical Turk for research on cancer survivors
Authors: Arch Joanna J. , Carr Alaina L. 
Published: June 2016

AbstractObjectiveThe successful recruitment and study of cancer survivors within psycho‐oncology research can be challenging, time‐consuming, and expensive, particularly for key subgroups such as young adult cancer survivors. Online crowdsourcing platforms offer a potential solution that has not yet been investigated with regard to cancer populations. The current study assessed the presence of cancer survivors on Amazon's Mechanical Turk (MTurk) and the feasibility of using MTurk as an efficient, cost‐effective, and reliable psycho‐oncology recruitment and research platform.MethodsDuring a <4‐month period, cancer survivors living in the United States were recruited on MTurk to complete two assessments, spaced 1 week apart, relating to psychosocial and cancer‐related functioning. The reliability and validity of responses were investigated.ResultsWithin a <4‐month period, 464 self‐identified cancer survivors on MTurk consented to and completed an online assessment. The vast majority (79.09%) provided reliable and valid study data according to multiple indices. The sample was highly diverse in terms of U.S. geography, socioeconomic status, and cancer type, and reflected a particularly strong presence of distressed and young adult cancer survivors (median age = 36 years). A majority of participants (58.19%) responded to a second survey sent one week later.ConclusionsOnline crowdsourcing represents a feasible, efficient, and cost‐effective recruitment and research platform for cancer survivors, particularly for young adult cancer survivors and those with significant distress. We discuss remaining challenges and future recommendations. Copyright © 2016 John Wiley & Sons, Ltd.
Realizing Product‐Packaging Combinations in Circular Systems: Shaping the Research Agenda
Authors: de Koeijer Bjorn , Wever Renee , Henseler Jörg 
Published: June 2016

Recent years have shown a shift in the focus of sustainable development from eco‐efficiency (minimizing negative impacts) towards eco‐effectiveness (optimizing positive impacts). Currently, a focus on circular models can be identified; Cradle to Cradle and circular economy are main examples of such models. However, the current number and variety of models and tools focusing on circular systems are limited with regard to packaging development.This paper explores packaging development models and tools in relation to circular systems, in order to identify the current status of the circularity focus. A range of identified models and tools is structured into two categories (generative and evaluative tools) which cover three types (protocols, diagrams and evaluations). This is in line with the distinction between early and later phases of development and the cumulative nature of environmental lock‐in. Protocol‐type models and tools come in different forms, such as principles, guidelines and checklists (e.g. Cradle to Cradle and DfE). Aside from these, eight diagram‐type models are analysed, focusing on packaging development, sustainable development and sustainable packaging development. In contrast to generative design tools, evaluation‐type models and tools (e.g. LCA) are most useful in the later stages of development processes.Resulting from the analysis of the models and tools, three types of integration – integrated product‐packaging development, the cross‐functional integration of actors and the front‐end integration of sustainability considerations – are appropriate for the development of product‐packaging combinations for circular systems. This leads to an agenda which shapes research directions towards achieving this development. © 2016 The Authors Packaging Technology and Science Published by John Wiley & Sons, Ltd.

Published: June 2016

Objective/Background The prevalence of depression in women is two times as much as that in men. However, the rehabilitation programme for return to work for patients with depression in Japan mainly focuses on male individuals. Japanese working women usually have the central role in housework in addition to paid work. Therefore, we hypothesized that Japanese working women with depression need a support programme for housework as well as paid work. The purpose of this study was to investigate the stress factors relevant to the existence of depression, in both paid work and housework, among working women. Methods This study recruited 35 women with depression and 35 women without depression. We carried out a cross-sectional investigation with two questionnaires having the same structure: The National Institute for Occupational Safety and Health (NIOSH) Generic Job Stress Questionnaire (for paid work) and the NIOSH Generic Housekeeping Labor Stress Questionnaire (for housework). We extracted the stress factors contributing to the existence of depression using logistic regression. Results Three stress factors were found–-two in housework, and one in paid work. In housework, variance in workload and underutilization of abilities were associated with the presence of depression. In paid work, interpersonal conflict was an associated factor. Conclusion Rehabilitation programmes involving variance in workload and under self-evaluation in housework, and interpersonal conflict in paid work must be adequately addressed to support working women with depression.
Population viewpoint on Hawkes processes
Authors: Boumezoued Alexandre 
Published: June 2016

AbstractIn this paper we focus on a class of linear Hawkes processes with general immigrants. These are counting processes with shot-noise intensity, including self-excited and externally excited patterns. For such processes, we introduce the concept of the age pyramid which evolves according to immigration and births. The virtue of this approach that combines an intensity process definition and a branching representation is that the population age pyramid keeps track of all past events. This is used to compute new distribution properties for a class of Hawkes processes with general immigrants which generalize the popular exponential fertility function. The pathwise construction of the Hawkes process and its underlying population is also given.
IMAGING ALL THE PEOPLE
Authors: Leitgeb Hannes 
Published: June 2016

AbstractIt is well known that aggregating the degree-of-belief functions of different subjects by linear pooling or averaging is subject to a commutativity dilemma: other than in trivial cases, conditionalizing the individual degree-of-belief functions on a piece of evidence E followed by linearly aggregating them does not yield the same result as first aggregating them linearly and then conditionalizing the resulting social degree-of-belief function on E. In the present paper we suggest a novel way out of this dilemma: adapting the method of update or learning such that linear pooling commutes with it. As it turns out, the resulting update scheme – (general) imaging on the evidence – is well-known from areas such as the study of conditionals and causal decision theory, and a formal result from which the required commutativity property is derivable was supplied already by Gärdenfors (1982) in a different context. We end up determining under which conditions imaging would seem to be right method of update, and under which conditions, therefore, group update would not be affected by the commutativity dilemma.

ON GORENSTEINNESS OF HOPF MODULE ALGEBRAS
Authors: SKRYABIN SERGE 
Published: June 2016

AbstractLet H be a Hopf algebra with a bijective antipode, A an H-simple H-module algebra finitely generated as an algebra over the ground field and module-finite over its centre. The main result states that A has finite injective dimension and is, moreover, Artin–Schelter Gorenstein under the additional assumption that each H-orbit in the space of maximal ideals of A is dense with respect to the Zariski topology. Further conclusions are derived in the cases when the maximal spectrum of A is a single H-orbit or contains an open dense H-orbit.

Systematic Tail Risk
Authors: van Oordt Maarten R. C. , Zhou Chen 
Published: June 2016

AbstractWe test for the presence of a systematic tail risk premium in the cross section of expected returns by applying a measure of the sensitivity of assets to extreme market downturns, the tail beta. Empirically, historical tail betas help predict the future performance of stocks in extreme market downturns. During a market crash, stocks with historically high tail betas suffer losses that are approximately 2 to 3 times larger than their low-tail-beta counterparts. However, we find no evidence of a premium associated with tail betas. The theoretically additive and empirically persistent tail betas can help assess portfolio tail risks.
Does Information-Processing Cost Affect Firm-Specific Information Acquisition? Evidence from XBRL Adoption
Authors: Dong Yi , Li Oliver Zhen , Lin Yupeng , Ni Chenkai 
Published: June 2016

AbstractWe examine how information-processing cost affects investors’ acquisition of firm-specific information using a natural experiment resulting from a recent mandate requiring U.S. firms to adopt eXtensible Business Reporting Language (XBRL) when submitting filings to the U.S. Securities and Exchange Commission (SEC). XBRL filings make financial data standardized, tagged, and machine readable. We find that XBRL adoption reduces firms’ stock return synchronicity. The reduction in synchronicity mainly applies to filings under the mandatory program as opposed to the voluntary program. Furthermore, such an effect is more pronounced for opaque and complex firms. Finally, we find that XBRL adoption also reduces price delay.
Making Waves: To Innovate or Be a Fast Second?
Authors: Yung Chris 
Published: June 2016

AbstractInternal finance leads to a stalemate in innovation games; each firm wants to free-ride on the others’ costly experimentation. When instead innovation is financed externally (e.g., with venture capital or initial public offerings), there is an endogenous cost to delay. Waiting to make risky irreversible investment conveys pessimistic information. I characterize the relative sizes of waves of leaders and followers in innovation cycles, and the endogenous, intertemporal distribution of quality as each wave builds and crashes. Finally, old waves leave an adverse selection “hangover,” such that too much early innovation can cause the market for future innovation to break down.
Time-Varying Margin Requirements and Optimal Portfolio Choice
Authors: Rytchkov Oleg 
Published: June 2016

AbstractThis paper studies the optimal consumption and portfolio problem of an investor with recursive preferences who is subject to time-varying margin requirements. The level of the requirements at each moment is determined by contemporaneous volatility of returns, which is stochastic and may have jumps. I show that the nonstandard hedging demand produced by margin requirements increases with their persistence and volatility. However, for realistic values of parameters, the hedging demand is small even in the presence of jumps, and contemporaneous jumps in prices have a much stronger effect on optimal portfolio than jumps in constraints.

Closed forms for convolutions of Catalan numbers
Authors: Gauthier N. 
Published: June 2016

In Catalan numbers with applications [1], Thomas Koshy gives a clear and accessible account of some of the important characteristics of Catalan numbers. The author also discusses the significance of these numbers for mathematicians, scientists, engineers and amateur enthusiasts alike. The general contents of his book are reviewed in [2]. Catalan numbers, which are named after the mathematician Eugene Catalan (1814-1894), have very interesting and sometimes surprising properties.Catalan numbers occur in combinatorial mathematics, in particular, where they show up as a natural number sequence that arises in counting problems that usually involve recursively-defined objects.
Digging for roots using the Pascal spade
Authors: Shirali Shailesh A. 
Published: June 2016

Here is a result which will surely make one sit up. We start with a sequence t1 = (1, 1, 2, 2, 4, 4, 8, 8, 16, 16, … ) in which each power of 2 occurs twice in succession, and produce a second sequence whose n th term is the sum of the n th and (n + 1) th terms of the original one; we get the sequence t2 = (2, 3, 4, 6, 8, 12, 16, 24, 32, … ). We repeat the same operation on the resulting sequence, and continue this, iteratively. Here are the sequences t3, t4, t5:t3 = (5, 7, 10, 14, 20, 28, 40, 56, 80, 1l2, 160, 224, 320, 448,…),t4 = (12, 17, 24, 34, 48, 68, 96, 136, 192, 272, 384, 544, 768,…),t5 = (29,41, 58, 82, 116, 164,232, 328, 464, 656, 928, 1312,…).If we compute the ratio of the second term to the first term for each ti, we get the following sequence of rational numbers,which converges to the square root of 2. (These fractions turn out to be successive convergents to the simple continued fraction for √2; see Section IV for details.)
How best should we vote?

Traditionally ‘Applied Mathematics’ meant mathematics applied to mechanics, physics and the hard sciences, leaving the application of mathematics to social sciences fairly neglected. This is both a challenge and an opportunity.An instance of this is in the science of voting.Let's go down to Chuddlehampton-upon-Severn to see how mathematics can be applied in a ‘real-life situation’. The good folk of this small village have to elect their local councillor, the person to represent them at the Regional Council. “Go and elect someone” was the only instruction they were given.

Genetic diversity and linkage disequilibrium in the Argentine public maize inbred line collection
Authors: Olmos Sofía E. , Lia Verónica V. , Eyhérabide Guillermo H. 
Published: June 2016

AbstractKnowledge of linkage disequilibrium (LD) patterns is considered a prerequisite for effective association mapping studies. However, no LD analysis in the Argentine public temperate maize collection has been reported to date. In this study, a panel of 111 temperate maize inbreds genotyped at 74 single sequence repeats (SSRs) loci was used to assess LD, genetic diversity and population structure to evaluate the suitability of the panel for association mapping. Mini-core sets were also designed for in-depth phenotyping and allele mining purposes. The panel consisted of: (1) locally developed orange flint germplasm; (2) temperate inbred lines with Iowa Stiff Stalk Synthetic background; and (3) eight historic flint lines, some of them from the Cuarentín race. As a result, four subpopulations were defined. Joint analysis of population structure and combining ability allowed identifying two main heterotic patterns. High molecular diversity, a low extent of LD and a high ratio of linked to unlinked SSR loci pairs in significant LD were detected indicating the suitability of the entire collection for association mapping. The fact that the LD extent in the mini-core sets was similar to that observed in the entire collection and that only a small percentage of allelic richness was reduced suggests that these mini-core sets are suitable to capture diversity, exploit phenotypic variance and discover useful variants representative of the entire collection.
