Equilibrium pricing of currency options under a discontinuous model in a two-country economy
Authors: Xing Yu , Yang Xiaoping 
Published: November 2015

Abstract
(Bakshi, G., and Z. Chen. 1997. “Equilibrium Valuation of Foreign Exchange Claims.” Journal of Finance 52: 799–826) studied equilibrium valuation for foreign exchange claims in the setting of the two-country Lucas-type economy. In Bakshi and Chen (1997), they assumed the money supplies follow two-factor stochastic volatility processes. Based on their model, we add two independent Poisson-type jumps, respectively into the process of money supply in each country. By solving a partial integro-differential equation (PIDE) for currency options, we get closed-form solutions of call currency option prices. Our model is a generalization of Bakshi and Chen (1997), and can contain a class of stochastic-volatility jump-diffusion (SVJD) models as special cases.
Substantive Importance and the Veil of Statistical Significance
Authors: McCaskey Kelly , Rainey Carlisle 
Published: November 2015

AbstractPolitical science is gradually moving away from an exclusive focus on statistical significance and toward an emphasis on the magnitude and importance of effects. While we welcome this change, we argue that the current practice of “magnitude-and-significance,” in which researchers only interpret the magnitude of a statistically significant point estimate, barely improves the much-maligned “sign-and-significance” approach, in which researchers focus only on the statistical significance of an estimate. This exclusive focus on the point estimate hides the uncertainty behind a veil of statistical significance. Instead, we encourage researchers to explicitly account for uncertainty by interpreting the range of values contained in the confidence interval. Especially when making judgments about the importance of estimated effects, we advise researchers to make empirical claims if and only if those claims hold for the entire confidence interval.

Abstract
Carbon nitrides are excellent candidates for extreme hardness materials. In this work, a new I4̅3m phase of C3N2 has been uncovered by replacing part of the nitrogen atoms in the cagelike diamondoid nitrogen N10 with carbon atoms. This phase is mechanically and dynamically stable up to at least 50 GPa. The elastic anisotropy of I4̅3m-C3N2 is investigated by comparing with previously proposed α-C3N2. The tensile directional dependence of Young’s modulus obeys the following trend: E
[111]>E
[110]>E
[100]. Electronic structure calculations reveal that I4̅3m-C3N2 is hole conducting. Hardness calculation shows that the I4̅3m-C3N2 is superhard with a hardness of 72.9 GPa.
Multi-Scale Long-Range Magnitude and Sign Correlations in Vertical Upward Oil–Gas–Water Three-Phase Flow

Published: November 2015

Abstract
In this article we apply an approach to identify the oil–gas–water three-phase flow patterns in vertical upwards 20 mm inner-diameter pipe based on the conductance fluctuating signals. We use the approach to analyse the signals with long-range correlations by decomposing the signal increment series into magnitude and sign series and extracting their scaling properties. We find that the magnitude series relates to nonlinear properties of the original time series, whereas the sign series relates to the linear properties. The research shows that the oil–gas–water three-phase flows (slug flow, churn flow, bubble flow) can be classified by a combination of scaling exponents of magnitude and sign series. This study provides a new way of characterising linear and nonlinear properties embedded in oil–gas–water three-phase flows.

Published: November 2015

Abstract
We have performed unbiased searches for the global minimum structures of (FeS)

n

+ (n=1–5) clusters using the CALYPSO method combined with density functional theory geometric optimisation. A large number of low-lying isomers are optimised at the B3PW91/6-311+G* theory level. Accurate ab initio calculations and harmonic vibrational analyses are undertaken to ensure that the optimised geometries are true minimum. They show that the most stable structures begin to exhibit three-dimensional (3D) configurations at n=3. The relative stabilities of (FeS)

n

+ clusters for the ground-state structures are analysed on the basis of binding energies and HOMO-LUMO gaps. The theoretical results indicate that the binding energies of (FeS)

n

+ tend to increase with cluster size. The maxima of HOMO-LUMO gaps (3.88 eV) for the most stable configurations appear at (FeS)+. Moreover, we have found that the (FeS)2
+ cluster possesses the lowest local magnetic moments compared to the other species. The origin of this magnetic phenomenon is also analysed in detail.
Robust and Rapid Air-Borne Odor Tracking without Casting
Authors: Bhattacharyya Urvashi , Bhalla Upinder Singh 
Published: November 2015

AbstractCasting behavior (zigzagging across an odor stream) is common in air/liquid-borne odor tracking in open fields; however, terrestrial odor localization often involves path selection in a familiar environment. To study this, we trained rats to run toward an odor source in a multi-choice olfactory arena with near-laminar airflow. We find that rather than casting, rats run directly toward an odor port, and if this is incorrect, they serially sample other sources. This behavior is consistent and accurate in the presence of perturbations, such as novel odors, background odor, unilateral nostril stitching, and turbulence. We developed a model that predicts that this run-and-scan tracking of air-borne odors is faster than casting, provided there are a small number of targets at known locations. Thus, the combination of best-guess target selection with fallback serial sampling provides a rapid and robust strategy for finding odor sources in familiar surroundings.

Published: November 2015

ObjectiveHereditary hypophosphatemias (HH) are rare monogenic conditions characterized by decreased renal tubular phosphate reabsorption. The aim of this study was to explore the prevalence, genotypes, phenotypic spectrum, treatment response, and complications of treatment in the Norwegian population of children with HH.DesignRetrospective national cohort study.MethodsSanger sequencing and multiplex ligand-dependent probe amplification analysis ofPHEXand Sanger sequencing ofFGF23,DMP1,ENPP1KL, andFAM20Cwere performed to assess genotype in patients with HH with or without rickets in all pediatric hospital departments across Norway. Patients with hypercalcuria were screened forSLC34A3mutations. In one family, exome sequencing was performed. Information from the patients' medical records was collected for the evaluation of phenotype.ResultsTwety-eight patients with HH (18 females and ten males) from 19 different families were identified. X-linked dominant hypophosphatemic rickets (XLHR) was confirmed in 21 children from 13 families. The total number of inhabitants in Norway aged 18 or below by 1st January 2010 was 1 109 156, giving an XLHR prevalence of ∼1 in 60 000 Norwegian children.FAM20Cmutations were found in two brothers andSLC34A3mutations in one patient. In XLHR, growth was compromised in spite of treatment with oral phosphate and active vitamin D compounds, with males tending to be more affected than females. Nephrocalcinosis tended to be slightly more common in patients starting treatment before 1 year of age, and was associated with higher average treatment doses of phosphate. However, none of these differences reached statistical significance.ConclusionsWe present the first national cohort of HH in children. The prevalence of XLHR seems to be lower in Norwegian children than reported earlier.

Underlying spirituality and mental health: the role of burnout: Rainbow Tin Hung Ho, et al. Centre on Behavioral Health, The University of Hong Kong, P.R.ChinaObjectiveThis study investigated the effects of burnout on the relationship between spirituality and mental health among healthcare workers in Hong Kong.MethodsUsing a cross‐sectional design, 312 healthcare workers (mean age=38.6, SD=9.9; 77.7% females) in a mental rehabilitation institution completed a self‐administered questionnaire on anxiety, depression, burnout, and daily spiritual experiences. Multivariate regressions were used to test the effects of burnout on the relationships between daily spiritual experiences and anxiety and depression.ResultsAfter adjusting for age, education level, marital status, and staff ranking, higher levels of daily spiritual experience were associated with lower levels of burnout (β =−0.22, p<0.01), depression (β =−0.68, p<0.01), and anxiety (β=−0.05, p<0.01). Burnout was found to have a significant partial mediating effect on the relationship between daily spiritual experiences and depression (z=−2.99, p<0.01), accounting for 37.8% of the variation in depression. Burnout also completely mediated the relationship between daily spiritual experiences and anxiety (z=−3.06, p<0.01), accounting for 73.9% of the variation in anxiety.ConclusionsThe results suggested that the association between spirituality and mental health is influenced by the level of burnout, thereby supporting the role of burnout as a potential mediator. Moreover, day‐to‐day spiritual practice was found to be potentially protective against burnout and mental health problems. Future interventions could incorporate spirituality training to reduce burnout so as to improve the well‐being of healthcare workers.

Effects of Paraoxonase 1 gene polymorphisms on organophosphate insecticide metabolism in Japanese pest control workers: Hirotaka Sato, et al. Department of Occupational and Environmental Health, Nagoya City University Graduate School of Medical SciencesObjectiveParaoxonase 1 (PON1) in serum detoxifies organophosphate (OP) insecticides by hydrolysis. The present crosssectional study aimed to clarify the relationship between PON1 single nucleotide polymorphisms (SNPs) and enzyme activities or OP metabolite concentrations in urine of workers occupationally exposed to low‐level OPs.MethodsAmong 283 workers in 10 pest control companies located in central Japan who underwent checkups, 230 subjects (male 199, female 31, average age 38.9 ± 11.1 years old) participated in the study. Q192R and L55M polymorphisms were determined by TaqMan assay. PON1 activity was measured using fenitrothion (FNT) oxon, chlorpyrifos‐methyl (CPM) oxon, chlorpyrifos (CP) oxon, and phenyl acetate as substrates. Urinary OP metabolite concentrations were measured with gas chromatography‐mass spectrometry.ResultsThe maximum differences in enzyme activities between individuals were 64.6‐, 6.3‐, 7.7‐, and 2.0‐fold for FNT oxonase, CPM oxonase, CP oxonase, and arylesterase (ARE), respectively. The activities of CPM oxonase and ARE in workers having the RR genotype were 53.5% and 18.2% lower than in those with the QQ genotype, respectively. CP oxonase activity was 15.0% lower in those having the M allele (LM + MM compared with LL). Urinary metabolite concentrations were not associated with PON1 polymorphisms, but negative associations were observed between the concentrations and activities of FNT oxonase and ARE.ConclusionsWhile PON1 SNPs can explain differences in catalytic activities toward some OPs, differences in urinary concentrations of OP metabolites are not attributable to PON1 SNPs but instead are attributable to its serum activities. Its serum activities might be more sensitive biomarkers for estimation of individual susceptibility to OP toxicities.

The opinions of occupational physicians about maintaining healthy workers by means of medical examinations in Japan using the Delphi method: Seiichiro Tateishi, et al. Occupational Health Training Center, University of Occupational and Environmental Health, JapanObjectiveIn Japan, employee fitness for work is determined by annual medical examinations. It may be possible to reduce the variability in the results of work fitness determination, particularly for situation, if there is consensus among experts regarding consideration of limitation of work by means of a single parameter.MethodsConsensus building was attempted among 104 occupational physicians by employing a 3‐round Delphi method. Among the medical examination parameters for which at least 50% of participants agreed in the 3rd round of the survey that the parameter would independently merit consideration for limitation of work, the values of the parameters proposed as criterion values that trigger consideration of limitation of work were sought. Parameters, along with their most frequently proposed criterion values, were defined in the study group meeting as parameters for which consensus was reached.ResultsConsensus was obtained for 8 parameters: systolic blood pressure 180 mmHg (86.6%), diastolic blood pressure 110 mmHg (85.9%), postprandial plasma glucose 300 mg/dl (76.9%), fasting plasma glucose 200 mg/dl (69.1%), Cre 2.0mg/dl (67.2%), HbA1c (JDS) 10% (62.3%), ALT 200 U/l (61.6%), and Hb 8 g/l (58.5%).ConclusionsTo support physicians who give advice to employers about work‐related measures based on the results of general medical examinations of employees, expert consensus information was obtained that can serve as background material for making judgements. It is expected that the use of this information will facilitate the ability to take appropriate measures after medical examination of employees.
