Comment on “A Model of Probabilistic Choice Satisfying First-Order Stochastic Dominance” by Pavlo Blavatskyy
Authors: Loomes Graham , Rodríguez-Puerta Inmaculada , Pinto-Prades Jose-Luis 
Published: November 2013

We present examples of existing evidence that lead us to be cautious about claims made in the original paper [Blavatskyy PR (2011) A model of probabilistic choice satisfying first-order stochastic dominance. Management Sci. 57(3):542–548] that the proposed model provides a better fit to experimental data than do existing models. We raise concerns about the accuracy of this and other assertions and about the adequacy of the comparisons made with alternative models in the existing literature.

Hip dysplasia in the young adult
Authors: Perry K. I. , Trousdale R. T. , Sierra R. J. 
Published: November 2013

The treatment of hip dysplasia should be customised for patients individually based on radiographic findings, patient age, and the patient’s overall articular cartilage status. In many patients, restoration of hip anatomy as close to normal as possible with a PAO is the treatment of choice. Cite this article: Bone Joint J 2013;95-B, Supple A:21–5.

Published: November 2013

ContextUnderstanding the relationship between union status and men's sexual risk behavior in their 30s is important to ensure appropriate reproductive health services for men in middle adulthood.MethodsData from 1,083 men aged 34–41 who participated in the 2008–2010 wave of the National Survey of Adolescent Males were used to examine differentials in sexual risk behaviors by union status, past risk behavior and selected characteristics. Bivariate tabulations were done to assess relationships between current risk behavior and background variables, multinomial regression analysis was conducted to identify associations between union status and past risk behavior, and logistic regression analysis was used to assess associations between current behavior and both union status and past behavior.ResultsEight percent of men in their 30s had had three or more sexual partners in the last 12 months, 10% had had at least one risky partner and 8% had had concurrent partners. Men living outside coresidential unions reported higher levels of these behaviors (24%, 29% and 24%, respectively) than did married men (1–2%) or cohabiting men (7–12%). In multivariate analyses that controlled for past risk behavior, married men were less likely than cohabiting men to have had at least one risky partner or concurrent partners in the last year (odds ratio, 0.2 for each), while men who were not in a coresidential union had an increased likelihood of reporting each risk behavior (2.2–5.3).ConclusionsMen in their 30s, especially those who are not married, engage in risky sexual behaviors. Further studies are needed to assess what contributes to behavioral differences by union status and what types of services might help men in this age‐group reduce their risk.
Photocatalytic Purification of Wastewater Polluted by Odorant Sulfur Compounds Using Titanium Oxide in a Continuous Photoreactor

Published: November 2013

Abstract
Using titanium dioxide, photocatalytic degradation of waste water polluted by commercial mercaptans (80% t-butyl mercaptan and 20% methyl ethyl sulfide) was investigated in a continuous photoreactor in the presence of UV irradiation. The reaction was performed at different pH of solution, intensity of irradiation, and initial concentration of odorant. Kinetics and mechanism of photocatalytic decomposition of mercaptans were studied by ex situ FTIR measurements of intermediates. The results showed that the photocatalytic process for degradation of mercaptans was an efficient method for mineralization of sulfur odorants in waste water. A proposed mechanism of mineralization of mercaptan was presented based on the results.
Conflict over Cooperation: Why So Much Disagreement over the Proposed Dairy Market Stabilization Program?
Authors: Jackson Jeremy Jay , Thraen Cameron S. , Bozic Marin 
Published: November 2013

Abstract
The creation of a Dairy Market Stabilization Program (DMSP) is a current topic of contention in the discussion of United States federal dairy policy. DMSP is designed to speed up income over feed cost (IOFC) margin recovery through triggered disincentives for milk production. This federally mandated supply control with its price-enhancing benefits to producers has proven to be controversial. The controversy surrounding DMSP implementation is illuminated by the construction of a stylized prisoner’s dilemma game in which DMSP acts as an enforceable commitment mechanism to restrict supply and prop up prices when feed costs experience an adverse shock. Volatile and high feed costs are likely to be the norm for the foreseeable future resulting in large expected benefits to milk producers if DMSP is implemented. The game shows that differing dairy management styles lead to different incentives regarding DMSP implementation as producer groups from feed-growing regions oppose DMSP in an effort to raise the costs of their rivals in feed-buying regions. Opposition to DMSP by feed growers can lead to increased market share and profitability in the future.
Exciting Prospects for Precise Engineering of Caenorhabditis elegans Genomes with CRISPR/Cas9
Authors: Frøkjær-Jensen Christian 
Published: November 2013

Abstract
With remarkable speed, the CRISPR–Cas9 nuclease has become the genome-editing tool of choice for essentially all genetically tractable organisms. Targeting specific DNA sequences is conceptually simple because the Cas9 nuclease can be guided by a single, short RNA (sgRNA) to introduce double-strand DNA breaks (DSBs) at precise locations. Here I contrast and highlight protocols recently developed by eight different research groups, six of which are published in GENETICS, to modify the Caenorhabditis elegans genome using CRISPR/Cas9. This reverse engineering tool levels the playing field for experimental geneticists.
More than the sum of the parts: forest climate response from joint species distribution models
Authors: Clark James S. , Gelfand Alan E. , Woodall Christopher W. , Zhu Kai 
Published: November 2013

The perceived threat of climate change is often evaluated from species distribution models that are fitted to many species independently and then added together. This approach ignores the fact that species are jointly distributed and limit one another. Species respond to the same underlying climatic variables, and the abundance of any one species can be constrained by competition; a large increase in one is inevitably linked to declines of others. Omitting this basic relationship explains why responses modeled independently do not agree with the species richness or basal areas of actual forests.We introduce a joint species distribution modeling approach (JSDM), which is unique in three ways, and apply it to forests of eastern North America. First, it accommodates the joint distribution of species. Second, this joint distribution includes both abundance and presence–absence data. We solve the common issue of large numbers of zeros in abundance data by accommodating zeros in both stem counts and basal area data, i.e., a new approach to zero inflation. Finally, inverse prediction can be applied to the joint distribution of predictions to integrate the role of climate risks across all species and identify geographic areas where communities will change most (in terms of changes in abundance) with climate change. Application to forests in the eastern United States shows that climate can have greatest impact in the Northeast, due to temperature, and in the Upper Midwest, due to temperature and precipitation. Thus, these are the regions experiencing the fastest warming and are also identified as most responsive at this scale.

Authors: Barreiro Bienvenido , Garcia Luis , Lozano Lourdes , Almagro Pere , Quintana Salvador , Alsina Monserrat , Heredia Jose Luis 
Published: November 2013

Obstructive sleep apnea (OSA) is a clinical picture characterized by repeated episodes of obstruction of the upper airway. OSA is associated with cardiovascular risk factors, some of which are components of metabolic syndrome (MS).

Objectives:
First, determine the prevalence of MS in patients with OSA visited in sleep clinic. Second, evaluate whether there is an independent association between MS components and the severity of OSA.

Methods:
Patients with clinical suspicion of OSA were evaluated by polysomnography. Three groups were defined according to apnea hypoapnea index (AHI): no OSA (AHI <5), mild-moderate (AHI≥ 5 ≤30), and severe (AHI> 30). All patients were determined in fasting blood glucose, total cholesterol, HDL cholesterol, triglycerides and insulin. MS was defined according to criteria of National Cholesterol Education Program (NCEP).

Results:
A total of 141 patients (mean age 54 ± 11 years) were evaluated. According to AIH, 25 subjects had no OSA and 116 had OSA (41mild-moderate and 75 severe). MS prevalence ranged from 43-81% in OSA group. Also, a significant increase in waist circumference, triglycerides, glucose, blood pressure levels, and a decrease in HDL cholesterol levels was observed in more severe OSA patients. All polysomnographic parameters correlated significantly with metabolic abnormalities. After a multiple regression analysis, abdominal obesity (p <0.02), glucose (p <0.01) and HDL cholesterol (p <0.001) were independently associated with OSA.

Conclusions:
Our findings show high prevalence of MS in OSA, especially in severe group. A significant association between OSA and some of the components of MS was found in Spanish population.
Transepithelial Photorefractive Keratectomy with Crosslinking for Keratoconus
Authors: Mukherjee Achyut N , Selimis Vasilis , Aslanides Ioannis 
Published: November 2013

Purpose:To analyse visual, refractive and topographic outcomes of combining transepithelial photorefractive keratectomy (tPRK) with simultaneous corneal crosslinking for the visual rehabilitation of contact lens intolerant keratoconus patients.Methods:Patients with topographically significant keratoconus, limited corrected vision and intolerant of contact lenses were prospectively recruited, subject to ethical approval and consent. All patients underwent single step aspheric tPRK and sequential crosslinking. Preoperative vision, refraction, corneal topography and wavefront were assessed, with postoperative assessment at 1, 3, 6, and 12 months.Results:22 eyes of 14 patients were included in the pilot study. Mean age was 32 years (SD 6.8, range 24 to 43). Mean preoperative unaided vision was 1.39 LogMAR (SD 0.5) best corrected 0.31 LogMAR (SD 0.2). Mean preoperative spherical equivalent was -2.74 Diopters (D) (SD 4.1 range -12.25 to +7.75), and mean cylinder -2.9 D (SD 1.2, range 0 to -5.5). Mean central corneal thickness was 461um (SD 29, range 411 to 516). Vision improved postoperatively; unaided 0.32 LogMAR (SD 0.4), best corrected 0.11 (SD 0.13) (P=<0.005). Mean postoperative cylinder was -1.4D (SD1.2), significantly reduced (p<0.005). Maximum keratometry (Kmax) was stable throughout postoperative follow up. (p<0.05).Conclusions:Non topographic transepithelial PRK with simultaneous crosslinking improves vision, and may offer an alternative to keratoplasty in contact lens intolerant keratoconus. Further comparative studies to topographic PRK techniques are indicated.
An Ecological View of Internet Health Information Seeking Behavior Predictors: Findings from the CHAIN Study
Authors: Calvert Joshua K , Aidala Angela A , West Josh H 
Published: November 2013

Objective:
The purpose of the study was to further elucidate proximal and distal demographic and social predictors of Internet Health Information Seeking Behavior (IHISB) among a cohort of HIV+ individuals through an ecological framework.

Methods:
The Community Health Advisory & Information Network (CHAIN) project is an ongoing prospective study of a representative sample of persons living with HIV/AIDS in New York City and the Tri-County region. The study sample was drawn from a two-stage randomized technique with the clients of 43 medical and social service organizations with 693 HIV+ participants. Bivariate correlations were computed between IHISB and independent demographic variables in ecological blocks. Multivariate hierarchical logistic regression was used to test association between blocks of variables and IHISB.

Results:
Among the surveyed respondents (n=645) 50.3% indicated that they used the Internet. Being above the poverty line, having less than a high school education, and having fewer neighbors were statistically significant predictors of IHISB related to HIV.

Conclusions:
The benefits of accessing the Internet may influence health behavior and may be considered a target for interventions that aim to increase access to health related information online. Coupled with increased access, is the need for increased patient education interventions, and creative managed care approaches to ensure that information gleaned from online sources is interpretable and accurate in order to benefit the lives of those living with HIV/AIDS.
A Comparison of Open Access in Exercise Science Journals: 2010 to 2012
Authors: Rattray Ben , Cooke Julie , Bail Kasia , Ranse Jamie 
Published: November 2013

The aim of this study was to complete an audit on the number of open access journals within the discipline of
Exercise Science. Publishing in open access journals results in wide dissemination of material in a very short period of
time compared with the more traditional way of publishing in a subscription journal. The 2010 ERA journal list, category
Human Movement and Sport Science, was initially utilised and then compared with the openness of the same journals in
2012.
In this study journals were audited for their degree of open access, open licensing and open format. Open access relates to
the free online availability of research results and hence research publications and in the discipline of exercise science
relates to the concept of an idealised level playing field. Open licensing relates to the ability of the consumers to replicate
and share those publications freely whilst open format relates to the use of open and transferrable format types. Open
access increased (p=0.014) as did our measurement of open licensing (p=0.000) and open formats (p=0.021) between the
2010 and 2012 reviews of the journals in 1106 For code.
This study reveals an increase in the number of Exercise Science journals that have full or partial open access over the two
year period and suggests that authors are increasingly adopting peer reviewed open access journal publications. It is
evident from this study that the impact of open access journals be assessed and further research into the feasibility of such
a rating is imperative.
Incidence, Outcomes, and Comparisons across Definitions of AKI in Hospitalized Individuals
Authors: Zeng Xiaoxi , McMahon Gearoid M. , Brunelli Steven M. , Bates David W. , Waikar Sushrut S. 
Published: November 2013

Summary

Background and objectives
At least four definitions of AKI have recently been proposed. This study sought to characterize the epidemiology of AKI according to the most recent consensus definition proposed by the Kidney Disease Improving Global Outcomes (KDIGO) Work Group, and to compare it with three other definitions.

Design, setting, participants, & measurements
This was a retrospective cohort study of 31,970 hospitalizations at an academic medical center in 2010. AKI was defined and staged according to KDIGO criteria, the Acute Dialysis Quality Initiative’s RIFLE criteria, the Acute Kidney Injury Network (AKIN) criteria, and a definition based on a model of creatinine kinetics (CK). Outcomes of interest were incidence, in-hospital mortality, length of stay, costs, readmission rates, and posthospitalization disposition.

Results
AKI incidence was highest according to the KDIGO definition (18.3%) followed by the AKIN (16.6%), RIFLE (16.1%), and CK (7.0%) definitions. AKI incidence appeared markedly higher in those with low baseline serum creatinine according to the KDIGO, AKIN, and RIFLE definitions, in which AKI may be defined by a 50% increase over baseline. AKI according to all definitions was associated with a significantly higher risk of death and higher resource utilization. The adjusted odds ratios for in-hospital mortality in those with AKI were highest with the CK definition (5.2; 95% confidence interval [95% CI], 4.1 to 6.6), followed by the RIFLE (2.9; 95% CI, 2.2 to 3.6), KDIGO (2.8; 95% CI, 2.2 to 3.6), and AKIN (2.6; 95% CI, 2.0 to 3.3) definitions. Concordance in diagnosis and staging was high among the KDIGO, AKIN, and RIFLE definitions.

Conclusions
The incidence of AKI in hospitalized individuals varies depending on the definition used. AKI according to all definitions is associated with higher in-hospital mortality and resource utilization. AKI may be inappropriately diagnosed in those with low baseline serum creatinine using definitions that incorporate percentage increases over baseline.

Published: November 2013

Summary

Background and objectives
The term C3 glomerulopathy describes renal disorders characterized by the presence of glomerular deposits composed of C3 in the absence of significant amounts of Ig. On the basis of electron microscopy appearance, subsets of C3 glomerulopathy include dense deposit disease (DDD) and C3 glomerulonephritis (C3GN). The full spectrum of histologic change observed in C3 glomerulopathy has yet to be defined and pathologic predictors of renal outcome within this patient population remain largely unknown. This study thus characterized a large C3 glomerulopathy cohort and identified clinicopathologic predictors of renal outcome.

Design, setting, participants, & measurements
All patients with kidney biopsies fulfilling criteria for C3 glomerulopathy from two quaternary renal centers within the United Kingdom and Ireland between 1992 and 2012 were retrospectively reviewed. We recorded histologic, demographic, and clinical data and determined predictors of ESRD using the Cox proportional hazards model.

Results
Eighty patients with C3 glomerulopathy were identified: 21 with DDD and 59 with C3GN. Patients with DDD were younger, more likely to have low serum C3 levels, and more likely to have crescentic GN than patients with C3GN. Patients with C3GN were older and had more severe arteriolar sclerosis, glomerular sclerosis, and interstitial scarring than patients with DDD. Of 70 patients with available follow-up data, 20 (29%) progressed to ESRD after a median of 28 months. Age >16 years, DDD subtype, and crescentic GN were independent predictors of ESRD within the entire cohort. Renal impairment at presentation predicted ESRD only among patients with DDD.

Conclusions
Although detailed serologic and genetic data are lacking, this study nevertheless identifies important clinicopathologic distinctions between patients with DDD and C3GN. These include independent predictors of renal outcome. If replicated in other cohorts, these predictors could be used to stratify patients, enabling application of emerging mechanism-based therapies to patients at high risk for poor renal outcome.
Network Ties Among Low-Tax Firms
Authors: Brown Jennifer L. , Drake Katharine D. 
Published: November 2013

ABSTRACT
This study examines (1) whether network ties help explain variation in tax avoidance, and (2) how the relation between network ties and tax avoidance varies depending on the nature and context of those ties. We posit that information on a range of tax-avoidance strategies is shared among firms through their social network connections. Using board interlocks to proxy for these connections, we find that firms with greater board ties to low-tax firms have lower cash ETRs themselves. Ties to low-tax firms are more influential when the focal firm and its network partner are operationally and strategically similar, as are ties created by executive directors. Board ties to low-tax firms are also more influential when the focal firm and its network partner engage the same local auditor. Overall, our results suggest that the influence of firms' network ties on their tax-avoidance behavior depends on the character of those ties.
A Method for Extracting Suspected Parotid Lesions in CT Images using Feature-based Segmentation and Active Contours based on Stationary Wavelet Transform
Authors: Wu T. Y. , Lin S. F. 
Published: November 2013

Abstract
Automatic suspected lesion extraction is an important application in computer-aided diagnosis (CAD). In this paper, we propose a method to automatically extract the suspected parotid regions for clinical evaluation in head and neck CT images. The suspected lesion tissues in low contrast tissue regions can be localized with feature-based segmentation (FBS) based on local texture features, and can be delineated with accuracy by modified active contour models (ACM). At first, stationary wavelet transform (SWT) is introduced. The derived wavelet coefficients are applied to derive the local features for FBS, and to generate enhanced energy maps for ACM computation. Geometric shape features (GSFs) are proposed to analyze each soft tissue region segmented by FBS; the regions with higher similarity GSFs with the lesions are extracted and the information is also applied as the initial conditions for fine delineation computation. Consequently, the suspected lesions can be automatically localized and accurately delineated for aiding clinical diagnosis. The performance of the proposed method is evaluated by comparing with the results outlined by clinical experts. The experiments on 20 pathological CT data sets show that the true-positive (TP) rate on recognizing parotid lesions is about 94%, and the dimension accuracy of delineation results can also approach over 93%.

Authors: Liang Qiaokang , Zhang Dan , Wang Yaonan , Ge Yunjian 
Published: November 2013

Abstract
This paper presents the design and analysis of a six-component Force/Torque (F/T) sensor whose design is based on the mechanism of the Compliant Parallel Mechanism (CPM). The force sensor is used to measure forces along the x-, y-, and z-axis (Fx, Fy and Fz) and moments about the x-, y-, and z-axis (Mx, My and Mz) simultaneously and to provide passive compliance during parts handling and assembly. Particularly, the structural design, the details of the measuring principle and the kinematics are presented. Afterwards, based on the Design of Experiments (DOE) approach provided by the software ANSYS®, a Finite Element Analysis (FEA) is performed. This analysis is performed with the objective of achieving both high sensitivity and isotropy of the sensor. The results of FEA show that the proposed sensor possesses high performance and robustness.
