Persistent geotropic direction‐changing positional nystagmus with a null plane: The light cupula
Authors: Kim Chang‐Hee , Kim Min‐Beom , Ban Jae Ho 
Published: October 2013

Objectives/HypothesisThe aim of this study was to characterize the clinical features and typical positional nystagmus in patients with persistent geotropic direction‐changing positional nystagmus (DCPN) and address the possible pathophysiology of the disease. Furthermore, the proportion of light cupula among the patients showing geotropic DCPN was investigated to assume the incidence of light cupula in those patients.Study DesignProspective case series.MethodsWe conducted a prospective case series study in 19 patients with persistent geotropic DCPN. Positional nystagmus during the bow and lean test and the supine head roll test was analyzed using videonystagmography.ResultsAll of the 19 patients showed persistent geotropic DCPN without latency. A null plane in which the nystagmus ceases was identified in all of 19 patients, and the intensity of nystagmus was stronger on one side in13 patients (68%) on supine head roll test. Overall, the affected side could be identified in 18 patients (95%). About 14.2% (19 of 134) of patients with geotropic DCPN could be diagnosed as having light cupula in the horizontal semicircular canal.ConclusionsThe patients with light cupula show persistent geotropic DCPN without latency. Affected side(s) can be determined by the direction and intensity of the characteristic positional nystagmus and the side of the null plane. The pathophysiology and treatment of light cupula still remain to be elucidated.Level of Evidence4. Laryngoscope, 124:E15–E19, 2014
Gucci versus Old Navy: Interplay of Brand Personality and Regulatory Focus in Advertising Persuasion
Authors: Kim Dong Hoo , Sung Yongjun 
Published: October 2013

ABSTRACTThe present research examines how brand personality and regulatory focus (promotion vs. prevention) interplay in affecting advertising message persuasiveness. In Experiment 1, the moderating role of brand personality with respect to regulatory focus is tested. The results show that a promotion‐framed advertising message is more persuasive for a fictitious exciting brand than is a prevention‐framed message, whereas a prevention‐framed (vs. promotion‐framed) message is more effective for a fictitious competent brand. To replicate Experiment 1 and further test the hypothesis, in Experiment 2, two real brands representing two additional brand personality dimensions (sophistication vs. sincerity) are tested and the influence of individuals’ self‐construal level is controlled. The findings reveal that individuals exposed to the sophisticated brand show a more positive attitude when the brand message is promotion framed. By contrast, individuals exposed to the sincere brand react more favorably when the brand is presented with a prevention‐framed advertising message.
The Yersinia enterocolitica Ysa type III secretion system is expressed during infections both in vitro and in vivo
Authors: Bent Zachary W. , Branda Steven S. , Young Glenn M. 
Published: October 2013

AbstractYersinia enterocolitica biovar 1B maintains two type III secretion systems (T3SS) that are involved in pathogenesis, the plasmid encoded Ysc T3SS and the chromosomally encoded Ysa T3SS. In vitro, the Ysa T3SS has been shown to be expressed only at 26°C in a high‐nutrient medium containing an exceptionally high concentration of salt – an artificial condition that provides no clear insight on the nature of signal that Y. enterocolitica responds to in a host. However, previous research has indicated that the Ysa system plays a role in the colonization of gastrointestinal tissues of mice. In this study, a series of Ysa promoter fusions to green fluorescent protein gene (gfp) were created to analyze the expression of this T3SS during infection. Using reporter strains, infections were carried out in vitro using HeLa cells and in vivo using the mouse model of yersiniosis. Expression of green fluorescent protein (GFP) was measured from the promoters of yspP (encoding a secreted effector protein) and orf6 (encoding a structural component of the T3SS apparatus) in vitro and in vivo. During the infection of HeLa cells GFP intensity was measured by fluorescence microscopy, while during murine infections GFP expression in tissues was measured by flow cytometry. These approaches, combined with quantification of yspP mRNA transcripts by quantitative reverse transcriptase‐polymerase chain reaction (qRT‐PCR), demonstrate that the Ysa system is expressed in vitro in a contact‐dependent manner, and is expressed in vivo during infection of mice.
IDSDDIP: a secure distributed dynamic IP configuration scheme for mobile ad hoc networks
Authors: Ghosh Uttam , Datta Raja 
Published: October 2013

SUMMARYIn IP‐based networks, IP address uniqueness is one of the most important requirements since a node has to participate in unicast communications and routing. Often nodes are assumed to have unique IP addresses configured a priori. However, this is not the case and cannot be achieved easily in mobile ad hoc networks (MANETs). Most of the existing dynamic address allocation schemes of MANET rely on network‐wide flooding for address solicitation and/or duplicate address detection. As a result, several types of security threats can be seen at the time of address allocation. In this paper, we present an ID‐based distributed dynamic IP configuration scheme that securely allocates IP addresses to the authorized nodes without flooding the entire network. Here each node acquires capability of generating unique IP addresses from its own IP address and can assign those addresses to the new nodes. The proposed scheme provides security against the associated threats with dynamic IP allocation protocol without the help of a trusted third party. It also efficiently handles the network partitioning and merging and reduces the chance of address conflicts. Performance analysis and simulation results are present to show that the proposed addressing scheme has low communication overhead and fairly low addressing latency with added security mechanisms compared to the similar existing dynamic address allocation schemes.

ObjectiveGrowing evidence indicates that the metabolic syndrome (MS) is rooted in adverse exposures during fetal life. The aim of this study was to assess the possible associations between biomarkers of inflammation during third trimester of pregnancy and markers of MS in adult offspring.MethodsHigh‐sensitive C‐reactive protein (CRP), tumor necrosis factor‐α (TNF‐α), interleukin‐1β (IL‐1β) and interleuki‐6 (IL‐6) were measured in serum samples obtained in gestational week 30. Offspring were clinically examined at age 20 years. Analyses based on 439 mother–offspring dyads were adjusted for maternal smoking during pregnancy, height, prepregnancy body mass index (BMI), education, and offspring's sex. Offspring MS markers included waist circumference, BMI, blood pressure, HOMA insulin resistance, and plasma levels of fasting glucose, triglycerides, cholesterol fractions, insulin, and leptin.ResultsThe median level was 2.8 (interquartile range = 3.3) µg/ml for CRP, for TNF‐α: 5.7 (3.2) pg/ml, for IL‐1β: 0.5 (0.4) pg/ml, and for IL‐6: 1.1 (0.7) pg/ml. Concentrations were not significantly associated with MS markers in the offspring. The results remained essentially unchanged after correction for potential confounding.ConclusionMarkers for subclinical inflammation in third trimester in healthy women were not associated with components of MS in their adult offspring.

Published: October 2013

ObjectiveThe prediction of successful aging by midlife body mass index (BMI) and waist circumference (WC) was examined.MethodsBMI/WC were assessed in 4869 persons (mean age 51.2, range 42‐63 in 1991/1993) and survival and successful aging (alive, no chronic disease at age >60 years, not in the worst age‐ and sex‐standardized quintile of cognitive, physical, respiratory,cardiovascular, and mental health) ascertained over a 16‐year follow‐up, analyzed using logistic regression adjusted for sociodemographic factors and health behaviors.Results507 participants died, 1008 met the criteria for successful aging. Those with BMI ≥ 30 kg/m2 had lower odds of successful aging (odds ratio or OR) = 0.37; 95% confidence interval or CI: 0.27, 0.50) and survival (OR = 0.55; 95% CI: 0.41, 0.74) compared to BMI between 18.5 and 25 kg/m2. Those with a large WC (≥102/88 cm in men/women) had lower odds of successful aging (OR = 0.41; 95% CI: 0.31, 0.54) and survival (OR = 0.57; 95% CI: 0.44, 0.73) compared with those with a small waist (<94/80 cm in men/women). Analysis with finer categories showed lower odds of successful aging starting at BMI ≥ 23.5 kg/m2 and WC 82/68 cm in men/women.ConclusionsOptimal midlife BMI and WC for successful aging might be substantially below the current thresholds used to define obesity.
Detecting the end of agreement between two long ranked lists
Authors: Sampath Srinath , Verducci Joseph S. 
Published: October 2013

AbstractWe propose an alternative approach to the problem recently posed by Hall and Schimek (Journal of the American Statistical Association, 107(498)(2012), 661–672): determining at what point the agreement between two rankings of a long list of items degenerates into noise. We modify the method of estimation in Fligner and Verducci's (Journal of the American Statistical Association, 83(403)(1988), 892–901) multistage model for rankings, from maximum likelihood of conditional agreement over a sample of rankings to a locally smoothed estimator of agreement. Through simulations we show that this modification performs very well under several conditions. We apply our technique as a stopping rule to supplement the tau‐path algorithm, developed by Yu et al. (Statistical Methodology 8(2011), 97–111), in an analysis of associations between gene expression and compound potency in cancer data, and discuss some ramifications as planned extensions. © 2013 Wiley Periodicals, Inc.

Climate Change Mitigation and Internationalization: The Competitiveness of Multinational Corporations
Authors: Chakrabarty Subrata , Wang Liang 
Published: October 2013

AbstractIn recent years, the debate about climate change and the competitiveness of multinational corporations (MNCs) has increased. Decision makers in MNCs often face ambiguities on how their business competitiveness could be impacted by their actions to mitigate climate change. By combining knowledge from the field of climatology with the management literature, this study suggests that climate change mitigation can enhance an MNC's competitiveness. We test the hypotheses using longitudinal panel data on US MNCs from 2001 to 2009. We find that MNCs that implement climate change mitigation are likely to see significant increase in sales effectiveness and product leadership but no significant increase in return on equity. Further, the positive influence of mitigation on sales effectiveness and product leadership is found to be more strongly positive when the MNC's internationalization is high. Hence, mitigation efforts positively impact at least two dimensions of competitiveness Ñ sales effectiveness and product leadership, particularly when internationalization is high. © 2013 Wiley Periodicals, Inc.
The Effects of Social Media on Environmental Sustainability Activities of Oil and Gas Multinationals in Nigeria
Authors: Nwagbara Uzoechi 
Published: October 2013

AbstractThis article explores the role of communication in shaping corporate social responsibility (CSR) policies, addressing stakeholders' criticisms of the multinationals' sustainability commitment and in building intangible assets like corporate reputation. Given the challenges posed by institutional pressures as well as pressures of climate change and social media technology, this article suggests that communication—social media—can be used to advance the multinationals' CSR commitment for a more sustainable future in Nigeria's Niger delta. In the era of new media communication, this is redoubled as multinational corporations (MNCs) as well as other stakeholders can effectively and rapidly influence policies and public opinion on social and environmental issues given the reach, speed, and user‐generated content application flexibility of social media. Thus, social media can serve as platforms to address sustainability issues, as well as the prolonged poor corporate‐stakeholder relations in the region, which is in the shadow of oil exploration and climate change. © 2013 Wiley Periodicals, Inc.
Suicide attempts in chronic pain patients. A register-based study
Authors: Stenager Elsebeth , Christiansen Erik , Handberg Gitte , Jensen Børge 
Published: October 2013

Abstract

Background
There are several studies about the relationship between depression and chronic non-malignant pain. These studies have shown that up to 50% of chronic pain patients are suffering from depression.
It is, therefore, reasonable to expect that pain patients would also have an increased risk of suicidal behaviour. This problem is not well studied.
Since 1990 the Centre for Suicide Research, Odense, Denmark has registered all suicide attempts in patients residing in the Region of Funen, Denmark.
The Pain Clinic, Odense University Hospital receives patients with chronic pain from the entire Region of Southern Denmark.

Purpose
The purpose of the study has been:
To investigate, whether patients treated in the Pain Clinic during the period from 1 January 2004 to 31 December 2009 had an increased risk of suicide attempts compared with the background population.

Materials and methods
The Register for Suicide Attempts (RSA) is a product of the WHO research programme WHO/EURO Multicentre Study on Para suicide. The RSA is a longitudinal person-based register. It contains information about people who have been in contact with the health care system in the County of Funen as a result of a suicide attempt.
The Pain Clinic, Odense University Hospital receives patients with non-malignant chronic pain from the Region of Southern Denmark with 1,194,659 inhabitants. Data about age, sex, and time of treatment for patients treated in the Pain Clinic during the period were registered. Time and method of the suicide attempts were registered in the RSA. By registry linkages between the patient registers it was possible to calculate any excess risk of suicide attempts in chronic pain patients in the study period.
We used a cohort design and calculated incidence rates (IR) and incidence rate ratios (IRRs) for suicide attempts, based on data from RSA. Poisson Regression analyses were used for calculation of IR and IRR for suicide attempts.

Results
In the study period from 1 January 2004 to 31 December 2009 1871 patients residing in the Region of Funen in Denmark were referred to The Pain Clinic.
In the patient group 258 suicide attempts in 110 persons were registered. In all 6% of the patient group had attempted suicide.
An increased risk of suicide attempts was found in the pain population as the incidence rate ratio (IRR) was 3.76 95% CI (3.22; 4.40). No statistical significant differences between men and women were found.

Conclusion
In a chronic non-malignant pain population, referred to a pain clinic, the risk of suicide attempts was increased.

Implications
It is important to be aware of risk factors for suicidal behaviour, i.e. pain history, depression, anxiety, abuse problems, and social problems when caring for patients with chronic pain. More knowledge and training of the staff caring for chronic pain patients are needed to decrease the risk of suicidal behaviour.
Effect of surfactant on two-layer channel flow
Authors: Samanta Arghya 
Published: October 2013

AbstractThe effect of insoluble surfactant on the interfacial waves in connection with a two-layer channel flow is investigated for low to moderate values of the Reynolds number. Previous studies focusing on Stokes flow (Frenkel & Halpern, Phys. Fluids, vol. 14, 2002, p. L45; Halpern & Frenkel, J. Fluid Mech., vol. 485, 2003, pp. 191–220) are extended by including the inertial effect and the study of low-Reynolds-number flow (Blyth & Pozrikidis, J. Fluid Mech., vol. 521, 2004b, pp. 241–250) is enlarged up to moderate Reynolds number. Linear stability analysis based on the Orr–Sommerfeld boundary value problem identifies a surfactant mode together with an interface mode. The presence of surfactant on the interfacial mode is stabilizing at high viscosity ratio and destabilizing at low viscosity ratio. The threshold of instability is determined as a function of the Marangoni number. A long-wave model is developed to predict the families of nonlinear waves in the neighbourhood of the threshold of instability. Far from the threshold, wave dynamics is explored under the framework of a three-equation model in terms of lower layer flow rate ${q}_{2} (x, t)$, lower liquid-layer thickness $h(x, t)$ and surfactant concentration $\Gamma (x, t)$. Primary instability analysis of a three-equation model captures the result of the Orr–Sommerfeld boundary value problem very well for quite large values of wavenumber. In the nonlinear regime, travelling wave solutions demonstrate deceleration of maximum amplitude and acceleration of speed with the Marangoni number at high viscosity ratio $m\gt 1$ and show completely the opposite behaviour at low viscosity ratio $m\lt 1$. However, both maximum amplitude and speed attain a fixed value with increasing Reynolds number and this leads to saturation of instability.
Is Opisthorchis viverrini an avian liver fluke?
Authors: Nawa Y. , Doanh P.N. , Thaenkham U. 
Published: October 2013

AbstractRecently, in the Journal of Helminthology (May 2013), Dao et al. reported that Opisthorchis viverrini-like flukes were found in the bile duct of domestic ducks in Vietnam. They stated that this is the first record of Opisthorchis sp. in birds in Vietnam. However, three Opisthorchis species – O. cheelis, O. longissimus and O. parageminus – in birds in Vietnam were described by Le in 2000. Amongst these, O. parageminus was first reported, by Oshmarin in 1970, as a new Opisthorchis species found in domestic ducks (Anas platyrhynchos) in Vietnam. Morphologially O. viverrini-like flukes described by Dao et al. are much more similar to O. parageminus than to O. viverrini. The phylogenetic trees of internal transcribed spacer 2 (ITS2) and cytochrome oxidase 1 (CO1) gene sequences also showed that the O. viverrini-like liver flukes from domestic ducks were closer to O. lobatus than to O. viverrini. Therefore, O. viverrini-like liver flukes reported by Dao et al. (2013) are most likely to be O. parageminus.
Biodiversity, distribution and abundance of zooplankton in the Iranian waters of the Caspian Sea off Anzali during 1996–2010
Authors: Bagheri Siamak , Niermann Ulrich , Mansor Mashhor , Yeok Foong Swee 
Published: October 2013

The mesozooplankton of the south-western Caspian Sea, off Anzali, sampled from 1996–2010, had undergone severe changes, especially after the year 2001, when the invasive ctenophore Mnemiopsis leidyi bloomed for the first time. Native species vanished or decreased, while invasive species such as Pleopis polyphemoides, Acartia tonsa, M. leidyi and the larvae of Balanus sp., plus Hediste diversicolor dominated the zooplankton. It could be stated that the increasing amount of nutrients since the early 1980s led to a decrease of endemic species and smoothed the way for opportunistic invader species, which outcompeted and depleted the endemic species in their turn. However, the major changes in the zooplankton community and possibly the blooming of M. leidyi during 2001–2002 were triggered by changing weather patterns, when a period with heavy rain at the end of the 1990s was followed by a prolonged drought (2001–2002). It is not clear to what extent M. leidyi was responsible for the disappearance of endemic Copepoda and Cladocera species such as Eurytemora grimmi, Limnocalanus grimaldii, Cercopagis pengoi, and Polyphemus exiguous, because the mesozooplantic invader species seemed to be more successful competitors than the endemic Caspian Sea fauna. Compared with other areas of the Caspian Sea, the development of the M. leidyi stock was moderate in the area under investigation. Mnemiopsis leidyi numbers and biomass increased from the beginning of sampling in 2001 to about 600 n.m−3 and 40–60 g wet weight m−3 until 2003. Since then the stock oscillated in this range until 2010.
What God only knows: a reply to Rob Lovering
Authors: FRISE MATTHEW 
Published: October 2013

AbstractRob Lovering has recently argued that God is not omniscient on the grounds that (1) in order to be omniscient a subject must not only know all truths always but also know what it's like not to know a truth, and (2) God cannot fulfil both of these requirements. I show that Lovering's argument is unsuccessful since he inadequately supports (1) and (2), and since there are several serious doubts about (2). I also show that Lovering does not otherwise indicate that God is not maximally great.
A cohort study in university students: investigation of risk factors for cytomegalovirus infection

Published: October 2013

SUMMARYLittle is known about the main routes of human cytomegalovirus (HCMV) transmission in young adult populations. This study investigated risk factors for HCMV transmission in young adults attending university over a 3-year period. Blood samples were tested for HCMV specific viral capsid antigen IgG by enzyme immunoassay. Being born in a developing country and having lived in Africa were associated with HCMV seropositivity at study onset. No risk factors were associated with HCMV seroconversion over the 3-year follow-up. In contrast to previous reports, sexual activity was not associated with HCMV seroprevalence or seroconversion.
