Mortality Deceleration and Mortality Selection: Three Unexpected Implications of a Simple Model
Authors: Wrigley-Field Elizabeth 
Published: January 2014

AbstractUnobserved heterogeneity in mortality risk is pervasive and consequential. Mortality deceleration—the slowing of mortality’s rise with age—has been considered an important window into heterogeneity that otherwise might be impossible to explore. In this article, I argue that deceleration patterns may reveal surprisingly little about the heterogeneity that putatively produces them. I show that even in a very simple model—one that is composed of just two subpopulations with Gompertz mortality—(1) aggregate mortality can decelerate even while a majority of the cohort is frail; (2) multiple decelerations are possible; and (3) mortality selection can produce acceleration as well as deceleration. Simulations show that these patterns are plausible in model cohorts that in the aggregate resemble cohorts in the Human Mortality Database. I argue that these results challenge some conventional heuristics for understanding the relationship between selection and deceleration; undermine certain inferences from deceleration timing to patterns of social inequality; and imply that standard parametric models, assumed to plateau at most once, may sometimes badly misestimate deceleration timing—even by decades.
The Cost of Disability in China

Published: January 2014

Abstract
We describe the degree to which household income is negatively associated with the prevalence of different types of disability (i.e., medical impairments) in China using data from the 2006 Second National Survey of Disabled Persons. We then calculate the extra costs of disability across different types of households and show how these costs differ by the type and severity of disability in both urban and rural areas. Finally, we use nationally representative panel data on persons with disabilities from 2007 to 2009 to examine the degree to which social security is reaching persons with different types and severity of disabilities in both urban and rural areas. We conclude that although the amount and coverage of social security for households with disabilities is increasing rapidly, it is still not enough to offset the income differential between households with and without disabled persons, especially when we account for the extra costs of disability.
On Cyclic Cohomology of ×-Hopf algebras
Authors: Hassanzadeh Mohammad 
Published: January 2014

AbstractIn this paper we study the cyclic cohomology of certain ×-Hopf algebras: universal enveloping algebras, quantum algebraic tori, the Connes-Moscovici ×-Hopf algebroids and the Kadison bialgebroids. Introducing their stable anti Yetter-Drinfeld modules and cocyclic modules, we compute their cyclic cohomology. Furthermore, we provide a pairing for the cyclic cohomology of ×-Hopf algebras which generalizes the Connes-Moscovici characteristic map to ×-Hopf algebras. This enables us to transfer the ×-Hopf algebra cyclic cocycles to algebra cyclic cocycles.

AbstractCretaceous granites are widespread in the North Dabie orogen, Central China, but their emplacement sequence and mechanism are poorly known. The Tiantangzhai Complex in the North Dabie Complex is the largest Cretaceous granitic suite consisting of six individual intrusions. In this study, zircon U–Pb ages are used to constrain the crystallization and protolith ages of these intrusions. The Shigujian granite is a syn-tectonic intrusion with an age of 141 Ma. This granite was emplaced under a compressional regime. Oscillatory rims of zircons have yielded two peaks at 137±1 Ma and 125±1 Ma. The 137±1 Ma peak represents the beginning of orogenic extension and tectonic collapse, whereas the 125±1 Ma peak represents widespread granitic magmatism. Zircon cores have yielded concordant ages between 812 and 804 Ma, which indicate a crystallization age for the protolith. The Tiantangzhai granites show relatively high Sr contents and high La/Yb and Sr/Y ratios. The Shigujian granite has positive Eu anomalies resulting from partial melting of a plagioclase-rich source in an over-thickened crust. Correspondingly, in situ Lu–Hf analyses from zircons yield high negative εHf(t) values from −24.8 to −26.6, with two-stage Hf model ages from 2748±34 to 2864±40 Ma, suggesting that the magmas were dominantly derived from partial melting of middle to lower crustal rocks. The Dabie orogen underwent pervasive NW–SE extension at the beginning of the early Cretaceous associated with subduction of the Palaeo-Pacific plate beneath eastern China.
The St Lawrence Platform and Appalachian deformation front in the St Lawrence Estuary and adjacent areas (Quebec, Canada): structural complexity revealed by magnetic and seismic imaging
Authors: PINET NICOLAS , LAVOIE DENIS , KEATING PIERRE , DUCHESNE MATHIEU 
Published: January 2014

AbstractNew magnetic and seismic datasets offer a unique opportunity to document the geometry of the Appalachian front in a poorly studied segment of the orogen. Interpretation of high-resolution magnetic data allows, for the first time, the documentation of the contact between the autochthonous St Lawrence Platform and the Appalachians and highlights the regional significance of previously poorly documented ENE faults that experienced post-Ordovician strike-slip motion. Seismic data reveal tectonic slices in the foreland domain underlying the Appalachians and show that the depth of the décollement at the base of the Appalachian tectonic wedge varies significantly. Taken together, geological, magnetic and seismic data suggest that the geometry of the Appalachian front exhibits significant variations in map and cross-section views and recorded a polyphased structural history.
THE COURT'SIN PERSONAMJURISDICTION IN CASES INVOLVING FOREIGN LAND
Authors: Wass Jack 
Published: January 2014

AbstractTheMoçambiquerule provides that an English court may not adjudicate on title to foreign immovable property. This article considers the primary exception to that rule: where the court assumes jurisdictionin personamto enforce a contractual or equitable claim concerning foreign immovable property against a defendant subject to the court's personal jurisdiction. It addresses two questions: how should the English court decide whether to assume jurisdiction in relation to foreign land, and if the positions are reversed, should an English court recognize or enforce the order of a foreign court affecting English land? As to the first question, this article argues that the orthodox English approach is anachronistic. English law applies thelex foriexclusively to determine whether an obligation exists which the court has jurisdiction to enforce. Instead, modern conflict of laws principles demand that the court should apply the proper law of the substantive claim in determining whether a sufficient equitable or contractual obligation exists. As to the second question, this article argues that despite the prevailing view that foreign non-money judgments are not enforceable in England, foreign orders in relation to English land are in principle entitled to recognition in a subsequent action in England by the successful claimant.
RE FLIGHTLEASE: THE ‘REAL AND SUBSTANTIAL CONNECTION’ TEST FOR RECOGNITION AND ENFORCEMENT OF FOREIGN JUDGMENTS FAILS TO TAKE FLIGHT IN IRELAND
Authors: Kenny David 
Published: January 2014

AbstractThe common law rules for recognition and enforcement of foreign judgments were radically reformulated by the Canadian Supreme Court in Beals v Saldanha. Few other common law jurisdictions have considered whether or not to follow Canada in this development in private International Law. In 2012, the Irish Supreme Court definitively rejected the Canadian approach. This note examines the judgment in that case, and assesses the reasoning of the Irish Court.
Geometry of the augmented disk graph
Authors: MA JIMING 
Published: January 2014

AbstractFor a handlebodyH, we define two graphs, the augmented disk graph$\mathcal{ADG}(H)$and the truncated augmented disk graph$\mathcal{TADG}(H)$, and we show they are hyperbolic in the sense of Gromov. In the process, we show they are quasi-isometric to two other disk graphs defined by U. Hamenstädt, the super conducting disk graph$\mathcal{SDG}(H)$and the electrified disk graph$\mathcal{EDG}(H)$respectively. So we reprove two theorems of Hamenstädt [12].Our approach uses techniques from Masur–Schleimer's study on the hyperbolicity of the disk graph$\mathcal{DG}(H)$[21].
Structural Power, the Copenhagen School and Threats to Chinese Security
Authors: Reeves Jeffrey 
Published: January 2014

AbstractThis article engages with current debates surrounding China's security by employing the concept of structural power and the Copenhagen School approach to security studies to measure threats to China's security. Building on existing Chinese and English language research on China's security drivers, the article develops a mechanism for determining how China's economic relations with small states in Asia negatively affect their domestic stability and how this instability then loops back to undermine China's strategic position. The article uses China's relations with Cambodia, Nepal and Mongolia as case studies.

AbstractIntroduction: Patients with absent pulmonary valve syndrome often present early with airway compression from aneurysmal pulmonary arteries. This study reviews our experience in managing absent pulmonary valve syndrome in later presenting children, and techniques used for managing airway compression. Methods: This study is a retrospective chart review of all patients who underwent repair of absent pulmonary valve syndrome from 2000 to 2012 at our institution. The primary endpoints were post-operative bronchoscopic and clinical evidence of persistent airway compression and need for reinterventions on the pulmonary arteries. Results: A total of 19 patients were included during the study period. The mean age at repair was 4.1±3.0 years (range 10 months–11 years). In all, seven patients had pre-operative bronchoscopic evidence of airway compression, which was managed by pulmonary artery reduction plasty in four patients and Lecompte manoeuvre in three patients. There were no peri-operative deaths. In patients with pulmonary artery plasty, two had no post-operative airway compression, one patient had improved compression, and one patient had unchanged compression. In patients managed with a Lecompte manoeuvre, two patients had no or trivial airway compression and one had improved compression. There were six late reinterventions or reoperations on the pulmonary arteries – two out of four in the pulmonary artery plasty group and one out of three in the Lecompte group. Conclusions: Most late-presenting patients with absent pulmonary valve syndrome do not have airway compression. Either pulmonary artery reduction plasty or the Lecompte manoeuvre can relieve proximal airway compression, without a significantly different risk of pulmonary artery reintervention between techniques.

Published: January 2014

AbstractIntroductionDuring disasters and complex emergencies, environmental conditions can adversely affect the performance of point-of-care (POC) testing. Knowledge of these conditions can help device developers and operators understand the significance of temperature and humidity limits necessary for use of POC devices. First responders will benefit from improved performance for on-site decision making.ObjectiveTo create dynamic temperature and humidity profiles that can be used to assess the environmental robustness of POC devices, reagents, and other resources (eg, drugs), and thereby, to improve preparedness.MethodsSurface temperature and humidity data from the National Climatic Data Center (Asheville, North Carolina USA) was obtained, median hourly temperature and humidity were calculated, and then mathematically stretched profiles were created to include extreme highs and lows. Profiles were created for: (1) Banda Aceh, Indonesia at the time of the 2004 Tsunami; (2) New Orleans, Louisiana USA just before and after Hurricane Katrina made landfall in 2005; (3) Springfield, Massachusetts USA for an ambulance call during the month of January 2009; (4) Port-au-Prince, Haiti following the 2010 earthquake; (5) Sendai, Japan for the March 2011 earthquake and tsunami with comparison to the colder month of January 2011; (6) New York, New York USA after Hurricane Sandy made landfall in 2012; and (7) a 24-hour rescue from Hawaii USA to the Marshall Islands. Profiles were validated by randomly selecting 10 days and determining if (1) temperature and humidity points fell inside and (2) daily variations were encompassed. Mean kinetic temperatures (MKT) were also assessed for each profile.ResultsProfiles accurately modeled conditions during emergency and disaster events and enclosed 100% of maximum and minimum temperature and humidity points. Daily variations also were represented well with 88.6% (62/70) of temperature readings and 71.1% (54/70) of relative humidity readings falling within diurnal patterns. Days not represented well primarily had continuously high humidity. Mean kinetic temperature was useful for severity ranking.ConclusionsSimulating temperature and humidity conditions clearly reveals operational challenges encountered during disasters and emergencies. Understanding of environmental stresses and MKT leads to insights regarding operational robustness necessary for safe and accurate use of POC devices and reagents. Rescue personnel should understand these principles before performing POC testing in adverse environments.FergusonWJ,LouieRF,TangCS,Paw UKT,KostGJ.Dynamic temperature and humidity environmental profiles: impact for future emergency and disaster preparedness and response.Prehosp Disaster Med.2014;29(1):1-8.
Natural capital investment under knightian uncertainty
Authors: Asano Takao , Shibata Akihisa 
Published: January 2014

AbstractIn this paper, we develop a simple two-period model of natural capital investment under Knightian uncertainty and analyze the effects of changes in the degree of ambiguity on the optimal natural capital investment. We find that the degree of Knightian uncertainty affects a government's natural capital investment. Moreover, we find that the direction of the effect of the Knightian uncertainty depends on the nature of uncertainty, that is, on whether the uncertainty is about the future level of natural capital or about the return from saving.
Obesity prevalence in Colombian adults is increasing fastest in lower socio-economic status groups and urban residents: results from two nationally representative surveys
Authors: Kasper Nicole M , Herrán Oscar F , Villamor Eduardo 
Published: January 2014

AbstractObjectiveLow- and middle-income countries are experiencing rises in the prevalence of adult obesity. Whether these increases disproportionately affect vulnerable subpopulations is unclear because most previous investigations were not nationally representative, were limited to women, or relied on self-reported anthropometric data which are subject to bias. The aim of the present study was to assess changes in the prevalence of obesity from 2005 to 2010 in Colombian adults; overall and by levels of sociodemographic characteristics.DesignTwo cross-sectional, nationally representative surveys.SettingColombia.SubjectsMen and women 18–64 years old (n 31 105 in 2005; n 81 115 in 2010).ResultsThe prevalence of obesity (BMI ≥30 kg/m2) was 13·9 % in 2005 and 16·4 % in 2010 (prevalence difference = 2·7 %; 95 % CI 1·9, 3·4 %). In multivariable analyses, obesity was positively associated with female sex, age, wealth, and living in the Pacific or National Territories regions in each year. In 2010, obesity was also associated with living in an urban area. The change in the prevalence of obesity from 2005 to 2010 varied significantly according to wealth; 5·0 % (95 % CI 3·3, 6·7 %) among the poorest and 0·3 % (95 % CI −1·6, 2·2 %) in the wealthiest (P, test for interaction = 0·007), after adjustment. Obesity rates also increased faster in older than younger people (P, test for interaction = 0·01), among people from urban compared with non-urban areas (P, test for interaction = 0·06) and in adults living in the Atlantic region compared with others.ConclusionsAdult obesity prevalence has increased in Colombia and its burden is shifting towards the poor and urban populations.
India's vitamin A supplementation programme is reaching the most vulnerable districts but not all vulnerable children. New evidence from the seven states with the highest burden of mortality among under-5s

AbstractObjectiveTo characterize the coverage of India's national vitamin A supplementation (VAS) programme and document its performance in reaching children in the districts with higher concentration of poor households (2006–2011).DesignAnalysis of VAS programme coverage data collated and collected using standardized bottom-up procedures, data from India's Office of the Registrar General and Census Commissioner, and data from India's District Level Household Survey to compute exposure (poverty) and outcome (full VAS coverage) variables.SettingSeven Indian states with the highest burden of mortality in children (74 % of all deaths among under-5s in the country in 2006).SubjectsChildren 6–59 months old.ResultsBetween 2006 and 2011, the mean full VAS coverage (two VAS doses per child per year) in these seven states increased from 44·7 % to 67·3 % while the number of districts with high (≥80 %) full VAS coverage increased from twenty-four (9·4 %) to 131 (51·4 %). The highest increases in full VAS coverage figures were recorded in the districts with the highest concentration of poor households. The estimated number of poor children (i.e. children living in households classified as poor) who did not receive two VAS doses annually decreased from 8·5 million in 2006 to 5·1 million in 2011 (40·3 % decrease); 2·5 million (49·1 %) of these children lived in the districts with the lowest proportion of poor households.ConclusionsDespite significant improvements in VAS, a large number of Indian children are not benefitting yet from this life-protecting intervention, particularly among those who are potentially the most vulnerable. Future programme action needs to give priority to sub-district level units – blocks and villages – with higher concentrations of poor households.
LESSONS STILL UNLEARNED
Authors: Harris Luke Charles 
Published: January 2014

AbstractIn this essay, I contend that the elevation of Clarence Thomas to the Supreme Court, and the evisceration of civil rights it has enabled, should be understood in part to reflect a tragic mistake on the part of Black America writ large. I will argue it represents the absence of a fully embodied vision of racial justice—one that genuinely symbolizes the entire panoply of concerns that must be addressed if the quest for racial equality is to ever be fully realized in the United States. Importantly, what this essay will point to is a political and discursive failure to center the concerns of Black females at the heart of our racial justice agenda.
Age, Growth, and Reproductive Biology of Cownose Rays in Chesapeake Bay
Authors: Fisher Robert A. , Call Garrett C. , Grubbs R. Dean 
Published: January 2014

Abstract
The Cownose Ray Rhinoptera bonasus is an opportunistic predator of benthic invertebrates and has had a long history of negative interactions with commercial shellfish industries. Most recently, Cownose Rays have been implicated in negatively affecting the recovery of bay scallop Argopecten irradians stocks in North Carolina and oyster restoration and commercial aquaculture efforts in Chesapeake Bay. A mitigation attempt to decrease predation on shellfish has resulted in an unregulated fishery for Cownose Rays. Cownose Ray life history suggests that they are highly susceptible to overexploitation. We determined age, growth, and size at maturity for Cownose Rays collected in Chesapeake Bay. In total, 694 rays were used for the study: 246 males ranging in size from 30.0 to 98.0 cm disc width (DW) and 448 females ranging from 30.0 to 110.5 cm DW. The oldest individual observed was a female (107 cm DW) estimated at age 21. Our data suggested that Cownose Rays grow considerably faster during the first few years than has been previously reported, thus producing higher estimates of the growth coefficient k. The best-fit growth models (three-parameter von Bertalanffy models) estimated k-values of 0.2741 for males and 0.1931 for females. The large sample size and inclusion of many older animals (n = 119 rays over age 10) resulted in theoretical maximum size estimates that matched the observed sizes well. The median size at 50% maturity was 85–86 cm DW for males and females (corresponding to ages of ∼6–7 for males and ∼7–8 for females). Fecundity in Cownose Rays was typically one embryo per mature female, with a gestation period of 11–12 months. Our study confirms that the Cownose Ray is a K-selected species with late maturity, long gestation, and low reproductive potential, indicating that it could be highly susceptible to overexploitation.

A Novel Approach to Surveying Sturgeon Using Side-Scan Sonar and Occupancy Modeling
Authors: Flowers H. Jared , Hightower Joseph E. 
Published: January 2014

Abstract
Technological advances represent opportunities to enhance and supplement traditional fisheries sampling approaches. One example with growing importance for fisheries research is hydroacoustic technologies such as side-scan sonar. Advantages of side-scan sonar over traditional techniques include the ability to sample large areas efficiently and the potential to survey fish without physical handling—important for species of conservation concern, such as endangered sturgeons. Our objectives were to design an efficient survey methodology for sampling Atlantic Sturgeon Acipenser oxyrinchus by using side-scan sonar and to develop methods for analyzing these data. In North Carolina and South Carolina, we surveyed six rivers thought to contain varying abundances of sturgeon by using a combination of side-scan sonar, telemetry, and video cameras (i.e., to sample jumping sturgeon). Lower reaches of each river near the saltwater–freshwater interface were surveyed on three occasions (generally successive days), and we used occupancy modeling to analyze these data. We were able to detect sturgeon in five of six rivers by using these methods. Side-scan sonar was effective in detecting sturgeon, with estimated gear-specific detection probabilities ranging from 0.2 to 0.5 and river-specific occupancy estimates (per 2-km river segment) ranging from 0.0 to 0.8. Future extensions of this occupancy modeling framework will involve the use of side-scan sonar data to assess sturgeon habitat and abundance in different river systems.
