Assessment of GIC risk due to geomagnetic sudden commencements and identification of the current systems responsible
Authors: Fiori R. A. D. , Boteler D. H. , Gillies D. M. 
Published: December 2013

AbstractDuring periods of enhanced geomagnetic activity, geomagnetically induced currents (GIC) flow in power systems potentially causing damage to system components or failure of the system. The largest GIC are produced when there are large rates of change of the geomagnetic field (dB/dt). It is well established that the main phase of a geomagnetic storm, particularly the magnetic substorms occurring during that period, is a cause of large GIC and hence a risk factor for power systems. However, some power system disturbances have been associated with the occurrence of a storm sudden commencement (SSC) prior to the main phase. We investigate the magnetic signature observed on the ground and the associated solar wind and interplanetary magnetic field (IMF) conditions for both SSC and sudden impulse (SI) events, which are grouped together as sudden commencements (SC). SCs are primarily attributed to a sudden enhancement of the magnetopause current. For some events, we show that there is a high‐latitude enhancement (HLE) of the SC amplitude and corresponding dB/dt. The limited spatial extent suggests an ionospheric current source. Examination of the polarity of the change in the X‐component magnetic field shows that the HLE is due to a sudden increase of the ionospheric convection electrojets. The occurrence of the HLE is more prevalent for SSC‐type SCs, SCs caused by coronal mass ejections as opposed to corotating interaction regions, and SCs associated with a large solar wind speed (vsw) prior to the SC or a large Δvsw at the time of the SC.
The Passenger Effect: Risky Driving is a Function of the Driver‐Passenger Emotional Relationship

Published: December 2013

SummaryThis research focused on the influence of imaginary passengers on drivers' estimation of the probability of having an accident in traffic situations. Participants had to imagine riding a motorcycle with either a son or a workmate as a passenger. Their task was to assess the risk of accident in a set of traffic scenarios. Risk perception was a function of sex and type of passenger. Women perceived higher risk when the passenger was a son than when a workmate. In contrast, men's estimations were rather the same for both passengers. The emotional significance of the consequences of the accident (losing a son vs. losing a workmate) modulate the perception of probability of having an accident. Finally, these results could help in designing more effective campaigns promoting road safety. Copyright © 2013 John Wiley & Sons, Ltd.

Published: December 2013

BackgroundThere is limited evidence that farm safety‐related interventions based solely on an educational element have an effect on injury rates. Our aim was to evaluate a New Zealand national educational program, FarmSafe™ Awareness, for its effect on injury rates.MethodsWe used a before‐after design followed by a historical cohort study of sheep, beef, and dairy farmers/workers. The outcomes were work‐related injuries, identified from workers compensation data. Cox regressions were used to compare intervention with matched control group rates.ResultsFarmSafe™ Awareness was associated with significantly higher rates of work‐related injury, than matched controls.ConclusionsIt is difficult to see how FarmSafe™ Awareness could be causing an increased rate of work‐related injury. We detected no reporting bias, and selection bias is likely to act in the opposite direction to the observed results. We conclude that there is no evidence that FarmSafe™ Awareness prevents farm injury. Am. J. Ind. Med. 57:458–467, 2014. © 2013 Wiley Periodicals, Inc.

Authors: Morikawa Miki , Hagiwara Akiyoshi , Sakamoto Taigo , Kimura Akio 
Published: December 2013

PatientA healthy 37‐year‐old man who bruised his chest with a steel frame developed ventricular fibrillation, pulseless ventricular tachycardia, and temporary torsade de pointes, and was resuscitated with emergency medical treatment. Thallium 201 scintigraphy 7 days later revealed a defect only in a small area of the apex, whereas 123I‐beta‐methyl iodophenyl pentadecanoic acid scintigraphy showed defects in a larger area of the apex, ventricular septum, and inferior wall, indicating perfusion–metabolism mismatch. Follow‐up dual myocardial scintigraphy on day 49 showed that the scintigraphic defects persisted only at a small area of the apex.ConclusionBlunt external force appeared to have caused perfusion–metabolism mismatch and subsequent life‐threatening arrhythmias in this patient.

Published: December 2013

ABSTRACTRed Monascus rice (Ang‐kak) is used as a traditional medicine and a natural colorant for food and beverages. Starch isolated from waste Ang‐kak may compete economically with other common starch and give new value to this waste. Isolation by using alkaline method gave a product with a starch content of 81%. Impurities in the product are protein, fiber, ash, and secondary metabolites of the Monascus rice. Several physicochemical properties of the isolated starch were also investigated. It was found that 88.03% of the isolated starch is amylopectin. Thermogravitation study showed that the isolated starch degraded only slightly at temperature below 230 °C and can be considered as a new source of starch for various applications. © 2013 Curtin University of Technology and John Wiley & Sons, Ltd.

Published: December 2013

BACKGROUNDCongenital heart disease (CHD) is estimated to affect between 3 and 5% of all newborns. Extra‐cardiac malformations are observed in 7 to 50% of patients with CHD. One relatively well‐known association that can occur in the context of CHD is VACTERL. Controversy still remains regarding the definition of VATER association and its expansion to VACTERL, the appropriate diagnostic criteria and the overall incidence.METHODSWe conducted a description of a case series to characterize the cardiac findings present in a cohort of patients meeting the criteria for VACTERL association.RESULTSForty‐six of 220 were eligible for inclusion into the study, 67% (31 of 46) had CHD. The most common CHD was ventricular septal defect, present in 18 of 31 patients (58%). There was no statistically significant association between CHD severity and the presence or absence of other VACTERL component features, specifically anorectal malformation (p = 0.18) or tracheo‐esophageal fistula (p = 0.72). CHD presence also did not correlate with the presence of tracheo‐esophageal fistula or anorectal malformation.CONCLUSIONAlthough this study does not, by design, provide further evidence toward the questions of whether CHD is a defining feature of VACTERL association, the frequency of CHD in our cohort does lend support to it being an important medical consideration in patients with VACTERL association. Based on our experience, we strongly recommend a screening echocardiogram to evaluate for CHD in individuals with a potential diagnosis of VACTERL association.

Published: December 2013

The objectives of this study were to visualize the surgical anatomical structures in the female pelvis by computed tomography and to investigate the components of the parametrium for anatomical education, radiological diagnosis, and surgical simulation. We surgically dissected fresh female cadavers maintained in precise surgical anatomic positions and examined the anatomical structures using experimental fine cell detector multislice computed tomography (FDCT) with a slice thickness of 0.3125 mm. In addition, we established a three‐dimensional (3D) reconstruction model for precise observation of the surgical anatomy using Materialise's Interactive Medical Image Control System (Mimics). We evaluated two‐dimensional (2D) images of the surgical anatomical structures in combination with the 3D reconstruction model. The 3D model was reconstructed from 430 serial axial pelvic CT images of a cadaver. The cardinal ligament, uterosacral ligament, paravesical space, and pararectal space were visualized on the CT images obtained from the surgically dissected part. The parametrium components were clearly distinguished on the surgically dissected side. Based on the information from the dissected side, these components on the undissected side could be distinguished as well. We recognized the parametrium components in the area extirpated during radical hysterectomy. The approach using cadavers, experimental FDCT, and 3D software provided excellent visualization of pelvic structures. High‐quality images of surgical anatomical structures provide new insight regarding precise surgical anatomy in the female pelvis. The radiological information has practical usefulness for radiotherapeutic planning and surgical simulation. Clin. Anat. 27:503–510, 2014. © 2013 Wiley Periodicals, Inc.
Pricing and power control for energy‐efficient radio resource management in cognitive femtocell networks
Authors: An Chunyan , Xie Renchao , Ji Hong , Li Yi 
Published: December 2013

SummaryCognitive femtocell has been considered as a promising technique that can improve the capacity and the utilization of spectrum efficiency in wireless networks because of the short transmission distance and low transmit power. In this paper, we study the win–win solution of energy‐efficient radio resource management in cognitive femtocell networks, where the macrocell tries to maximize its revenue by adjusting spectrum utilization price while the femtocells try to maximize their revenues by dynamically adjusting the transmit power. When the spectrum utilization price is given by macrocell, we formulate the power control problem of standalone femtocells as an optimization problem and introduce a low‐complexity iteration algorithm based on gradient‐assisted binary search algorithm to solve it. Besides, non‐cooperative game is used to formulate the power control problem between collocated femtocells in a collocated femtocell set, and then low complexity and widely used gradient‐based iteration algorithm is applied to obtain the Nash‐equilibrium solution. Specially, asymptotic analysis is applied to find the approximate spectrum utilization price in macrocell, which can greatly reduce the computational complexity of the proposed energy‐efficient radio resource management scheme. Finally, extensive simulation results are presented to verify our theoretical analysis and demonstrate the performance of the proposed scheme. Copyright © 2013 John Wiley & Sons, Ltd.
Hoarding severity predicts functional disability in late‐life hoarding disorder patients

Published: December 2013

ObjectiveLate‐life hoarding is a serious psychiatric condition with significant implications in health and functioning. Geriatric hoarding patients show greater impairment in activities of daily living and have a greater number of medical conditions compared with same‐aged nonhoarders. This study examined the relationship between geriatric hoarding severity and functional disability severity.MethodsSixty‐five subjects age 60 or older with hoarding disorder (HD) participated in the current study. Participants were assessed with measures of hoarding severity, psychiatric symptoms, and general disability. Hierarchical regression was used to test the unique association of hoarding symptoms with functional disability beyond the effects of demographic factors, anxiety, and depression.ResultsWhen controlling for demographics (age and gender) and psychiatric symptoms (anxiety and depression), hoarding severity predicts functional disability severity. Analyses also show that clinician‐administered measures of hoarding are stronger predictors of disability than patient self‐report measures.ConclusionsWhen treating older adults with HD, clinicians must consider symptom impact on daily life. A multidisciplinary team must be utilized to address the wide‐ranging consequences of hoarding symptoms. Future work should examine how psychiatric treatment of HD affects functional disability.

AbstractMultitasking (MT) constitutes engaging in two or more cognitive activities at the same time. MT‐training improves performance on untrained MT tasks and alters the functional activity of the brain during MT. However, the effects of MT‐training on neural mechanisms beyond MT‐related functions are not known. We investigated the effects of 4 weeks of MT‐training on regional gray matter volume (rGMV) and functional connectivity during rest (resting‐FC) in young human adults. MT‐training was associated with increased rGMV in three prefrontal cortical regions (left lateral rostral prefrontal cortex (PFC), dorsolateral PFC (DLPFC), and left inferior frontal junction), the left posterior parietal cortex, and the left temporal and lateral occipital areas as well as decreased resting‐FC between the right DLPFC and an anatomical cluster around the ventral anterior cingulate cortex (ACC). Our findings suggest that participation in MT‐training is as a whole associated with task‐irrelevant plasticity (i.e., neural changes are not limited to certain specific task conditions) in regions and the network that are assumed to play roles in MT as well as diverse higher‐order cognitive functions. We could not dissociate the effects of each task component and the diverse cognitive processes involved in MT because of the nature of the study, and these remain to be investigated.

Leader self‐awareness: An examination and implications of women's under‐prediction
Authors: Sturm Rachel E. , Taylor Scott N. , Atwater Leanne E. , Braddy Phillip W. 
Published: December 2013

SummarySelf‐awareness represents an important aspect of leadership. However, past research on leader self‐awareness has focused on one component of self‐awareness, self versus others' ratings, leaving the second component, the ability to anticipate the views of others, largely neglected. We examined this second component of self‐awareness by focusing on women leaders who have been found to under‐predict how others rate them. In two studies, we measured how women leaders anticipate the views of their bosses in regard to their leadership. In Study 1, 194 leaders rated their leadership, were rated by their bosses, and then predicted how their bosses rated their leadership. While we found that women under‐predict their boss ratings compared with men, we did not find that boss gender or feedback played a role in this under‐prediction. In Study 2, 76 female leaders identified (via open‐ended questions) possible reasons and consequences of under‐prediction for women in organizations. Results from Study 2 reveal the following: (1) the reasons for women's under‐prediction include a lack of self‐confidence, differences in feedback needs, learned gender roles, and self‐sexism; and (2) the perceived consequences of under‐prediction are negative for both women and the organization.

Activation of hedgehog signaling during fracture repair enhances osteoblastic‐dependent matrix formation

Published: December 2013

ABSTRACTFracture repair is a well orchestrated process involving various cell types and signaling molecules. The hedgehog signaling pathway is activated in chondrocytes during fracture repair and is known to regulate chondrogenesis however, its role in osteoblasts during injury is yet unknown. In this study we observed tibial fracture repair in mice in which hedgehog signaling was modulated through genetic alterations of the pathway activator, smoothened. Levels of the hedgehog target genes Gli1 and Ptch1 in wildtype mice were upregulated in fracture calluses throughout the repair process. Forced activation of the hedgehog pathway in ubiquitous fashion resulted in increased matrix deposition in the fracture callus. Interestingly, inhibition in chondrocytes did not alter the fracture repair phenotype, while activation of hedgehog in osteoblasts was a requirement for normal fracture repair. In vitro, transcript levels of Gli1 and Ptch1 were elevated during osteoblastogenesis. Activation of hedgehog signaling positively affected osteoblastic differentiation and mineralization as detected using alkaline phosphatase and Von Kossa staining and Alp and Col1 expression. Here we show that the hedgehog signaling pathway plays a critical role in osteoblasts during fracture repair: inhibition of the pathway in osteoblasts leads to decreased matrix at the fracture site while activation increased matrix deposition.© 2013 The Authors.

The role of vascular endothelial growth factor and vascular stability in diseases of the ear
Authors: London Nyall R. , Gurgel Richard K. 
Published: December 2013

Objectives/HypothesisVascular endothelial growth factor (VEGF) is a critical mediator of vascular permeability and angiogenesis and likely plays an important role in cochlear function and hearing. This review highlights the role of VEGF in hearing loss associated with vestibular schwannomas, otitis media with effusion, and sensorineural hearing loss.Study DesignPubMed literature review.MethodsA review of the literature was conducted to determine the role of VEGF in diseases affecting hearing.ResultsTherapeutic efficacy has been demonstrated for the anti‐VEGF agent bevacizumab in vestibular schwannomas, with tumor size reduction and hearing improvement in patients with neurofibromatosis type 2. The loss of functional Merlin, the protein product of the nf2 gene, results in a decrease in expression of the anti‐angiogenic protein SEMA3F through a Rac‐1–dependent mechanism, allowing VEGF to promote angiogenesis. Bevacizumab may therefore restore the angiogenic balance through inhibiting the relative increase in VEGF. Many of the clinical findings of otitis media with effusion can be reproduced by delivery of recombinant VEGF through transtympanic injection or submucosal osmotic pump. VEGF receptor inhibitors have been demonstrated to improve hearing in an animal model of otitis media with effusion. VEGF affects both the inner ear damage and repair processes in sensorineural hearing loss.ConclusionsVEGF has an important role in vestibular schwannomas, otitis media with effusion, and sensorineural hearing loss.
