Temporal Externalism and the Normativity of Linguistic Practice
Authors: Rouse Joseph 
Published: March 2014

Abstract
Temporal externalists expand Putnam’s and Burge’s semantic externalisms to argue that later uses of words transform the semantic significance (extension or meaning) of earlier uses. Conflicting intuitions about temporal externalism often turn on different conceptions of linguistic practice, which have mostly not been thematically explicated. I defend a version of temporal externalism that replaces the familiar regularist and normative-regulist conceptions of linguistic practice or use. This alternative identifies practices neither by regularities of use, nor by determinate norms governing their constituent performances, but by the ways those performances bear upon and are accountable to one another. Performances are intelligible as part of a larger pattern of practice, but different performances extend that pattern in partially conflicting ways. The essentially anaphoric concepts of “issues” and “stakes” allow us to talk about how alternative extensions of past performance conflict or otherwise mis-align (what is “at issue” in those performances), and what differences it would make to extend the practice in one way rather than another (what is “at stake”). The result is to recognize both the interdependence of linguistic performances, and the open texture of concepts, by situating them within broader patterns of discursive interaction with changing circumstances.
Historical Understanding in China and the West
Authors: Ivanhoe Philip J. 
Published: March 2014

Abstract
This essay describes and compares three attempts to provide accounts of the nature of historical consciousness, along with accompanying explanations of how one comes to have historical knowledge. It explores, compares, and contrasts the views of the late Qing dynasty Chinese philosopher Zhang Xuecheng 章學誠 (1738–1801) and two Western philosophers – R.G. Collingwood (1889–1943) and Louis O. Mink (1921–83). These three thinkers all present historical understanding as a distinctive type of knowledge and share the aim of defending the discipline of history as a special, independent field of intellectual endeavor. Aside from analyzing these aspects of their respective theories, this essay aims to stimulate extensive and nuanced comparisons between Chinese and more recent Western forms of historical consciousness. While the comparison presented here is but one way forward, it not only seeks to offer specific insights generated by the comparative project but also to set forth a range of themes worthy of future study. For example, the analysis presented here shows that Zhang’s reflections on how historians relate to the past can contribute to current discussions of epistemic virtues.
Taking a Look at History
Authors: Kindi Vasso 
Published: March 2014

AbstractIan Hacking urged that philosophers take a look at history. He called his recommendation the “Lockean imperative”. In the present paper I examine how Hacking understands the relation between philosophy and history by concentrating on his 1990 essay “Two kinds of ‘New Historicism’ for philosophers”. In this particular paper Hacking uses the visual metaphor of ‘taking a look’ which can also be found in the work of two other philosophers, Kuhn and Foucault, who are called by Hacking his mentors. I argue that in the work of these three philosophers, as well as in the work of Wittgenstein who has influenced both Hacking and Kuhn, one can find interest and attention to particulars which can be furnished by history, an approach which cultivates a sensibility for difference. I begin by presenting Hacking’s understanding of the relation of history to philosophy and then discuss what the Lockean imperative is. I concentrate on Locke’s understanding of history which differs considerably from the contemporary and end by focusing on the similarities in the work of the aforementioned thinkers.
Stratocumulus-Topped Marine Boundary Layer Processes Revealed by the Absence of Profiler Reflectivity
Authors: Hartten Leslie M. , Johnston Paul E. 
Published: March 2014

AbstractStratocumulus (Sc) clouds occur frequently over the cold waters of the southeastern Pacific Ocean. Data collected during two Pan American Climate Study research cruises in the tropical eastern Pacific illuminate many aspects of this Sc-topped marine boundary layer (MBL). Here the focus is on understanding gaps in detectable wind-profiler reflectivities during two boreal autumn cruises. After rigorous quality control that included applying the Riddle threshold of minimum signal-to-noise ratio (SNR) detectability, there are many instances with no measurable atmospheric signals through a depth of up to several hundred meters, often lasting for an hour or more. Rain gauge data from the autumn 2004 cruise are used to calibrate the profiler, which allows SNR to be converted to both equivalent reflectivity and the structure-function parameter of the index of refraction . Profiles of statistics from the two profiler modes (resolutions) highlight the wide range of during a 24-h period and bound the atmosphere’s when low-mode gaps are not mirrored in the high-mode data. Considering the gaps in terms of allows them to be understood as indications of reduced “top down” buoyancy processes and/or reduced turbulent intensity, both of which have been demonstrated by previous researchers to be associated with decoupling within the Sc-topped MBL. A decoupling index calculated from surface and ceilometer data strongly suggests that decoupled conditions were common and that the MBL was coupled when gaps in profiler reflectivity were unlikely. Further study of data from other cruises may lead to a method of using profiler reflectivity as an indicator of decoupled conditions.
Wind-Climate Estimation Based on Mesoscale and Microscale Modeling: Statistical–Dynamical Downscaling for Wind Energy Applications
Authors: Badger Jake , Frank Helmut , Hahmann Andrea N. , Giebel Gregor 
Published: March 2014

AbstractThis paper demonstrates that a statistical–dynamical method can be used to accurately estimate the wind climate at a wind farm site. In particular, postprocessing of mesoscale model output allows an efficient calculation of the local wind climate required for wind resource estimation at a wind turbine site. The method is divided into two parts: 1) preprocessing, in which the configurations for the mesoscale model simulations are determined, and 2) postprocessing, in which the data from the mesoscale simulations are prepared for wind energy application. Results from idealized mesoscale modeling experiments for a challenging wind farm site in northern Spain are presented to support the preprocessing method. Comparisons of modeling results with measurements from the same wind farm site are presented to support the postprocessing method. The crucial element in postprocessing is the bridging of mesoscale modeling data to microscale modeling input data, via a so-called generalization method. With this method, very high-resolution wind resource mapping can be achieved.
An Expanded Dataset of Hurricane Eyewall Sizes and Slopes
Authors: Stern Daniel P. , Brisbois James R. , Nolan David S. 
Published: April 2014

Abstract
Using airborne Doppler radar data from 39 flights into hurricanes from 2004 to 2010, the authors examine the outward slope of the eyewall, revisiting the recent studies of Stern and Nolan. The slope of the radius of maximum winds (RMW) is found to increase nearly linearly with size and is uncorrelated with intensity. The slope of the eyewall absolute angular momentum surface M increases with increasing size (strong correlation) and decreases with increasing intensity (weak to moderate correlation). Two other measures of eyewall slope are also investigated: the 20-dBZ reflectivity isosurface (dBZ20) and the radius of maximum azimuthal-mean updraft (RWMAX). The slopes of both dBZ20 and RWMAX increase with their size. The slope of dBZ20 decreases with intensity, though the correlation is weak, while the slope of RWMAX is uncorrelated with intensity. The absolute angular momentum decreases on average along the RMW by 9% from 2- to 8-km heights. With this larger dataset, the previous results are generally confirmed: the slope of the eyewall is mostly a function of the size of the RMW.
The vertical decay rate of the maximum tangential winds (Vmax) is also reexamined. On average, Vmax decreases by 20% from 2- to 8-km heights, but this varies from 8% to as large as 42%. This percentage decay rate increases with increasing size and decreases with increasing intensity. Three cases are found where Vmax increases with height from 2 to 4 km, which is likely a consequence of unbalanced flow.
Contribution of Tropical Cyclones to Global Very Deep Convection
Authors: Jiang Haiyan , Tao Cheng 
Published: March 2014

Abstract
Based on the 12-yr (1998–2009) Tropical Rainfall Measuring Mission (TRMM) precipitation feature (PF) database, both radar and infrared (IR) observations from TRMM are used to quantify the contribution of tropical cyclones (TCs) to very deep convection (VDC) in the tropics and to compare TRMM-derived properties of VDC in TCs and non-TCs. Using a radar-based definition, it is found that the contribution of TCs to total VDC in the tropics is not much higher than the contribution of TCs to total PFs. However, the area-based contribution of TCs to overshooting convection defined by IR is 13.3%, which is much higher than the 3.2% contribution of TCs to total PFs. This helps explain the contradictory results between previous radar-based and IR-based studies and indicates that TCs only contribute disproportionately large amount of overshooting convection containing mainly small ice particles that are barely detected by the TRMM radar. VDC in non-TCs over land has the highest maximum 30- and 40-dBZ height and the strongest ice-scattering signature derived from microwave 85- and 37-GHz observations, while VDC in TCs has the coldest minimum IR brightness temperature and largest overshooting distance and area. This suggests that convection is much more intense in non-TCs over land but is much deeper or colder in TCs. It is found that VDC in TCs usually has smaller environmental shear but larger total precipitable water and convective available potential energy than those in non-TCs. These findings offer evidence that TCs may contribute disproportionately to troposphere-to-stratosphere heat and moisture exchange.
Changes in Cyclone Characteristics in Response to Modified SSTs
Authors: Graff L. S. , LaCasce J. H. 
Published: March 2014

Abstract
The impact of changes in sea surface temperature (SST) on the statistics of extratropical cyclones is investigated. The cyclones were identified in an atmospheric general circulation model (AGCM) using an objective Lagrangian tracking algorithm, applied to the 850-hPa relative vorticity. The statistics were generated for several 20-yr simulations, in which the SSTs were warmed or cooled by 2 K in latitudinal bands. The response was studied in both hemispheres, during summer and winter.
Changes in the position of the storm tracks are largely consistent with those seen in previous studies. Increasing SSTs uniformly or increasing the midlatitude SST gradient results in a poleward shift in the storm tracks, with the clearest trends seen in the Southern Hemisphere (SH). Here it is demonstrated that the SST modifications alter the cyclone characteristics as well. When the warming includes the low latitudes and/or the midlatitude gradient is increased, there are more short-lived cyclones. These are also on average more intense and translate faster, both poleward and eastward.
The poleward displacement is correlated with cyclone intensity, so that stronger cyclones translate to higher latitudes. This is suggestive of vortex self-advection in the presence of a mean potential vorticity (PV) gradient. The increased eastward translation is correlated with the depth-averaged zonal velocity, and so is likely related to an increase in the steering-level velocity. These changes in cyclone translation probably contribute to the changes in the storm tracks seen previously.
Impacts of Parameterized Langmuir Turbulence and Nonbreaking Wave Mixing in Global Climate Simulations
Authors: Fan Yalin , Griffies Stephen M. 
Published: March 2014

Abstract
The impacts of parameterized upper-ocean wave mixing on global climate simulations are assessed through modification to Large et al.’s K-profile ocean boundary layer parameterization (KPP) in a coupled atmosphere–ocean–wave global climate model. The authors consider three parameterizations and focus on impacts to high-latitude ocean mixed layer depths and related ocean diagnostics. The McWilliams and Sullivan parameterization (MS2000) adds a Langmuir turbulence enhancement to the nonlocal component of KPP. It is found that the Langmuir turbulence–induced mixing provided by this parameterization is too strong in winter, producing overly deep mixed layers, and of minimal impact in summer. The later Smyth et al. parameterization modifies MS2000 by adding a stratification effect to restrain the turbulence enhancement under weak stratification conditions (e.g., winter) and to magnify the enhancement under strong stratification conditions. The Smyth et al. scheme improves the simulated winter mixed layer depth in the simulations herein, with mixed layer deepening in the Labrador Sea and shoaling in the Weddell and Ross Seas. Enhanced vertical mixing through parameterized Langmuir turbulence, coupled with enhanced lateral transport associated with parameterized mesoscale and submesoscale eddies, is found to be a key element for improving mixed layer simulations. Secondary impacts include strengthening the Atlantic meridional overturning circulation and reducing the Antarctic Circumpolar Current. The Qiao et al. nonbreaking wave parameterization is the third scheme assessed here. It adds a wave orbital velocity to the Reynolds stress calculation and provides the strongest summer mixed layer deepening in the Southern Ocean among the three experiments, but with weak impacts during winter.

Abstract
Heavy rainfall and flooding associated with tropical cyclones (TCs) are responsible for a large number of fatalities and economic damage worldwide. Despite their large socioeconomic impacts, research into heavy rainfall and flooding associated with TCs has received limited attention to date and still represents a major challenge. The capability to adapt to future changes in heavy rainfall and flooding associated with TCs is inextricably linked to and informed by understanding of the sensitivity of TC rainfall to likely future forcing mechanisms. Here a set of idealized high-resolution atmospheric model experiments produced as part of the U.S. Climate Variability and Predictability (CLIVAR) Hurricane Working Group activity is used to examine TC response to idealized global-scale perturbations: the doubling of CO2, uniform 2-K increases in global sea surface temperature (SST), and their combined impact. As a preliminary but key step, daily rainfall patterns of composite TCs within climate model outputs are first compared and contrasted to the observational records. To assess similarities and differences across different regions in response to the warming scenarios, analyses are performed at the global and hemispheric scales and in six global TC ocean basins. The results indicate a reduction in TC daily precipitation rates in the doubling CO2 scenario (on the order of 5% globally) and an increase in TC rainfall rates associated with a uniform increase of 2 K in SST (both alone and in combination with CO2 doubling; on the order of 10%–20% globally).
Forecaster Use and Evaluation of Real-Time 3DVAR Analyses during Severe Thunderstorm and Tornado Warning Operations in the Hazardous Weather Testbed

Published: March 2014

Abstract
A weather-adaptive three-dimensional variational data assimilation (3DVAR) system was included in the NOAA Hazardous Weather Testbed as a first step toward introducing warn-on-forecast initiatives into operations. NWS forecasters were asked to incorporate the data in conjunction with single-radar and multisensor products in the Advanced Weather Interactive Processing System (AWIPS) as part of their warning-decision process for real-time events across the United States. During the 2011 and 2012 experiments, forecasters examined more than 36 events, including tornadic supercells, severe squall lines, and multicell storms. Products from the 3DVAR analyses were available to forecasters at 1-km horizontal resolution every 5 min, with a 4–6-min latency, incorporating data from the national Weather Surveillance Radar-1988 Doppler (WSR-88D) network and the North American Mesoscale model. Forecasters found the updraft, vertical vorticity, and storm-top divergence products the most useful for storm interrogation and quickly visualizing storm trends, often using these tools to increase the confidence in a warning decision and/or issue the warning slightly earlier. The 3DVAR analyses were most consistent and reliable when the storm of interest was in close proximity to one of the assimilated WSR-88D, or data from multiple radars were incorporated into the analysis. The latter was extremely useful to forecasters in blending data rather than having to analyze multiple radars separately, especially when range folding obscured the data from one or more radars. The largest hurdle for the real-time use of 3DVAR or similar data assimilation products by forecasters is the data latency, as even 4–6 min reduces the utility of the products when new radar scans are available.
Improvement in Sensorineural Hearing Loss During Pregnancy
Authors: Stevens Madelyn N. , Hullar Timothy E. 
Published: March 2014

Objective: Hearing loss is known to occur in some pregnant women, but improvement in sensorineural thresholds has not been audiometrically characterized. Here, we describe a patient with a history of Ménière’s disease and vestibular migraine who experienced temporary recovery of her hearing during pregnancy. Methods: Audiograms were obtained from a 31-year-old female over the course of 2 successive pregnancies. Results: Audiograms revealed a substantial improvement in hearing by the third trimester during each pregnancy, with a rapid return to baseline thresholds after delivery. Conclusion: This case is unique in documenting improvements in hearing thresholds during pregnancy and substantiates the effects of hormonal changes on hearing thresholds in humans. It raises the intriguing possibility of hormonal therapy as a treatment for sensorineural hearing loss in specific clinical situations.

Published: March 2014

Objective: Immunoglobulin (Ig) G4-related disease is systemic, and it has been reported that patients with IgG4-related disease complain of symptoms involving numerous organs. However, there are few reports concerning the otologic manifestations of IgG4-related disease. The purpose of this study is to investigate the clinical features of the otologic manifestations in IgG4-related disease. Methods: We recruited 39 consecutive patients diagnosed with IgG4-related disease. Otologic symptoms, laboratory data, and audiogram findings were retrospectively examined. Mucosal tissues from the inferior turbinate were obtained from subjects before treatment. The serum IgG4 and eosinophil levels together with clinical features were analyzed. Results: Five of the 39 cases had some otologic symptoms. Otitis media with effusion was present in 2 patients. Sensorineural hearing loss was also present in 1 patient. Eosinophilic otitis media was present in 2 patients with bilateral rhinosinusitis and bronchial asthma, and elevated serum eosinophil levels. Oral prednisolone was effective in the treatment of IgG4-related disease. Conclusion: We revealed a new clinical entity associated with the otologic manifestations of IgG4-related disease.

Published: March 2014

Background The use of serum prostate-specific antigen (PSA) as a screening tool for prostate cancer in asymptomatic men is hugely controversial in the light of randomised controlled trials failing to demonstrate a benefit without risk of significant overtreatment. However, PSA can be used as a tool to risk assess disease progression in men with lower urinary tract symptoms suggestive of benign prostatic enlargement (LUTS/BPE). The aim of this study was to canvas the opinions of West of Scotland Urologists regarding the use of PSA in both symptomatic and asymptomatic patients. Methods A questionnaire-based survey was sent to all the Consultants and Trainees in the West of Scotland. Results Survey response rate was 45% (47/105). In patients <70 years, 93% would perform a PSA testing in patients symptomatic of LUTS/BPE, but only 17% would offer PSA screening to asymptomatic patients. In patients >70 years, only 48% of urologists would perform a PSA if patients were symptomatic and none would offer PSA screening. In terms of self-testing, 59% of urologists would have a PSA test if symptomatic and 31% of urologists would have PSA screening. Conclusions This study highlights significant variability in the use of PSA for both asymptomatic and symptomatic men. Despite a lack of evidence, PSA screening is still offered to asymptomatic men. Further randomised studies are required to determine the utility of PSA-based screening algorithms for prostate cancer detection.
Pseudoaneurysm of the sural artery: a rare complication of lower limb angioplasty
Authors: Aziz Abdul , Green Allan , Maskova Jana , Rajagopalan Sriram , Bachoo Paul 
Published: March 2014

Introduction Percutaneous transluminal angioplasty (PTA) is a common therapeutic option for the treatment of peripheral vascular disease. Pseudoaneurysm at the puncture site is a well-documented complication in patients. Case presentation This case report describes a patient who presented to hospital several days following a left superficial femoral and popliteal artery PTA with lower limb pain and swelling. The working diagnosis included a deep vein thrombosis based on the Wells criteria. However, a combination of a duplex scan and computed tomography angiography confirmed a clinically rare occurrence of pseudoaneurysm of the sural artery, a branch of the popliteal artery. This was managed successfully with a thrombin injection, leading to complete resolution of the patient’s symptoms. Conclusion This case highlights the importance of the technical aspects of performing a PTA. We believe that the guide-wire position was not confirmed to be completely in the popliteal artery upon inflation of the balloon.
