Published: February 2013

Background The posterior interosseous nerve (PIN) is at risk for injury during one-incision distal biceps tendon repair using a cortical button. The purpose of this study was to evaluate the proximity of a cortical button to the PIN during one-incision repairs of the distal biceps tendon using human cadaveric models. Method In ten cadaveric elbows the biceps tendon was identified, traced to its insertion, and transected. With the forearm supinated, a guide pin was drilled through the radial tuberosity at a 0°, perpendicular to the table. A dorsal incision was used to identify the PIN. The tendon was repaired with a cortical button, ensuring the device lay in line with the radial shaft. The distance from the device to the PIN was measured using digital calipers. This process was repeated with the guide pin aimed at 20° proximal toward the radiocapitellar joint (RCJ) and 30° distal toward the wrist. The data were compared using a Student's paired t-test. Results The average distance from the device to the PIN with the straight posterior insertion was 8.94 mm, 11.86 mm with 20° proximal, and 0.55 mm with 30° distal angles. The distance between the button and the PIN was significantly greater when aiming the device 20° toward the RCJ compared to the straight insertion technique ( p =0.0061). Conclusions The distance between the PIN and cortical button can be significantly increased by aiming the guide pin between 0° and 20° proximal toward the RCJ and placing the device in line with the radial shaft.

AbstractTo investigate whether 4‐methylcatechol (4MC) could decrease the duration of the thermosensation disorder and promote the innervation of peptidergic intraepidermal nerve fibers (IENFs), we developed a resiniferatoxin (RTX)‐induced neuropathic mouse model with thermal analgesia and skin denervation that was followed by daily 4MC treatment. On day 7 after RTX administration (RTXd7), the substance P (SP)(+) IENFs were completely depleted compared with the vehicle group (p < 0.0001), whereas the calcitonin gene‐related peptide (CGRP)(+) IENFs were dramatically, but not completely, depleted (p < 0.0001). While SP(+) IENFs remained depleted (p = 0.0043), CGRP(+) IENFs were recovered by RTXd84 (p = 0.78). 4MC had no effect on the reinnervation of SP(+) IENFs, but markedly promoted the reinnervation of CGRP(+) IENFs on RTXd35 (p = 0.035). On RTXd56, CGRP(+) IENFs were comparable with the vehicle group (p = 0.39). In addition, 4MC normalized thermal analgesia on RTXd35 compared with RTX group (p = 0.007). In the current study, the significant promotion of reinnervation of CGRP(+) IENFs and thermal latencies on RTXd35 by 4MC indicated that CGRP(+) IENFs were responsible for the thermal transmission in chronic phase of RTX‐induced neuropathy.
The poetics of resistance and the politics of crossing borders: Korean hip-hop and ‘cultural reterritorialisation’
Authors: Um Hae-Kyung 
Published: February 2013

AbstractThis paper examines the ways in which hip-hop has taken root in Korean popular culture. The processes that began in the early 1990s include appropriation, adaptation and ‘cultural reterritorialisation’. By looking at recent Korean hip-hop outputs and their associated contexts, this paper explores the ways in which Korean hip-hop has gained its local specificities. This was achieved by combining and recontextualising Afro-American and Korean popular musical elements and aesthetics in its performance and identification in the context of the consumption and commodification of Korean hip-hop as a ‘national(ised) cultural product’.
Numerical investigation of the effects of smoothing by spectral dispersion on stimulated rotational Raman scattering

Published: February 2013

AbstractThe effect of smoothing by spectral dispersion (SSD) on stimulated rotational Raman scattering (SRRS) in air has been investigated both numerically and theoretically. The suppression effect of SSD on SRRS process is verified and it is demonstrated and proposed that the suppression effect is attributed to two aspects: the decreasing of the laser fluence modulation degree and the reducing of Stokes gain coefficient caused by the temporal and spatial variation of the phase of the incident laser pulse. The simulation results show that the SRRS threshold distance can be lengthened by choosing appropriate SSD parameters.
Navigation of non-communicating autonomous mobile robots with guaranteed connectivity
Authors: Cezayirli Ahmet , Kerestecioğlu Feza 
Published: February 2013

SUMMARYWe consider the connectivity of autonomous mobile robots. The robots navigate using simple local steering rules without requiring explicit communication among themselves. We show that using only position information of neighbors, the group connectivity can be sustained even in the case of bounded position measurement errors and the occlusion of robots by other robots in the group. In implementing the proposed scheme, sub-optimal solutions are invoked to avoid an excessive computational burden. We also discuss the possibility of deadlock which may bring the group to a standstill and show that the proposed methodology avoids such a scenario in real-life settings.
Using automated planning for improving data mining processes

Published: February 2013

AbstractThis paper presents a distributed architecture for automating data mining (DM) processes using standard languages. DM is a difficult task that relies on an exploratory and analytic process of processing large quantities of data in order to discover meaningful patterns. The increasing heterogeneity and complexity of available data requires some expert knowledge on how to combine the multiple and alternative DM tasks to process the data. Here, we describe DM tasks in terms of Automated Planning, which allows us to automate the DM knowledge flow construction. The work is based on the use of standards that have been defined in both DM and automated-planning communities. Thus, we use PMML (Predictive Model Markup Language) to describe DM tasks. From the PMML, a problem description in PDDL (Planning Domain Definition Language) can be generated, so any current planning system can be used to generate a plan. This plan is, again, translated to a DM workflow description, Knowledge Flow for Machine Learning format (Knowledge Flow file for the WEKA (Waikato Environment for Knowledge Analysis) tool), so the plan or DM workflow can be executed in WEKA.
Learning Individualism: Hesse, Confucius, and Pep-Rallies in a Chinese Rural High School
Authors: Hansen Mette Halskov 
Published: February 2013

AbstractIn Chinese public discourse, it has almost become a truism that the generation born after the mid-1980s is more selfish, individualistic, and materialistic than previous generations. Consequently, an important task for public moral education is to correct this behaviour and to generate compassion for others beyond the family, to strengthen nationalist sentiments and to imbue a sense of duty to the greater community. Schools provide the Chinese government with a key opportunity to achieve this. Based on fieldwork in a rural high school in China, this article demonstrates how the official visions of the learned individual portrayed in textbooks collide with a more powerful ideology of individualism that is implicitly promoted through activities within the school, and is reflective of an ongoing process of individualization, not only in Chinese society, but also within state institutions, such as the school.

SUMMARYMultiple norovirus outbreaks following catered events in Auckland, New Zealand, in September 2010 were linked to the same catering company and investigated. Retrospective cohort studies were undertaken with attendees of two events: 38 (24·1%) of 158 surveyed attendees developed norovirus-compatible illness. Attendees were at increased risk of illness if they had consumed food that had received manual preparation following cooking or that had been prepared within 45 h following end of symptoms in a food handler with prior gastroenteritis. All food handlers were tested for norovirus. A recombinant norovirus GII.e/GII.4 was detected in specimens from event attendees and the convalescent food handler. All catering company staff were tested; no asymptomatic norovirus carriers were detected. This investigation improved the characterization of norovirus risk from post-symptomatic food handlers by narrowing the potential source of transmission to one individual. Food handlers with gastroenteritis should be excluded from the workplace for 45 h following resolution of symptoms.
Une composante «émotive» dans les constructions articulées par unetd'opposition?
Authors: CORMINBOEUF GILLES 
Published: February 2013

RÉSUMÉDans des enchaînements que l'on interprète adversativement, commeL'homme est né libre, et partout il est dans les fers(Rousseau,Du contrat social), le choix deet(plutôt quepourtantoumaisqui marqueraient l'opposition) n'est pas anodin. En conjoignant des prédications contradictoires au moyen deet, on transmet implicitement un genre d’«émotion» (ici une incrimination). Ce jugement de valeur véhiculéimplicitementpar l'enchaînement de deux énonciations est sans doute un des ressorts de l'expressivité (notion rarement définie) dont la parataxe est réputée être l'auxiliaire. Ces contradictions sont des stratégies raisonnables, dans la mesure où elles visent un implicite que l'allocutaire devra reconstruire lui-même pour surmonter ce qui, en apparence, constitue un paradoxe.
Erythrocytosis and severe asphyxia: two different causes of neonatal myocardial infarction
Authors: Caruso Elio , Di Pino Alfredo , Poli Daniela , Manuri Lucia , Guccione Paolo 
Published: February 2013

AbstractNeonatal acute myocardial infarction is a rare event that carries a high mortality rate. We describe the cases of two newborns who survived acute myocardial infarction and discuss the management. The first neonate was born with severe asphyxia and left ventricular myocardial infarction with ventricular tachycardia. In this patient, systemic flow was maintained by right-to-left shunting through the patent ductus arteriosus. The second neonate presented with a haematocrit of 80% and an inferolateral myocardial infarction. Intensive treatment of low cardiac output syndrome led to survival of both high-risk neonates. In the follow-up, at 48 and 4 months, respectively, ventricular function recovered in both patients.

AbstractTo determine whether cardiac catheterisation procedures for low birth weight neonates ≤2.5 kg carries a greater risk of complications compared with neonates >2.5 kg, we conducted a single-centre retrospective case–control study. From 01/03 to 01/09, 46 consecutive neonates <2.5 kg at the time of cardiac catheterisation were identified. For each low birth weight case, three control patients >2.5 kg were randomly selected from our heart centre database during the same time period. Data included demographic characteristics, type of intervention, fluoroscopy time, contrast volume, pre- and post-blood urea nitrogen to creatinine ratio, physician performing procedure, procedural risk category, and all major and minor complications. The overall incidence of complications was higher in neonates ≤2.5 kg compared with neonates >2.5 kg (34.8% versus 17.6%, p = 0.023) because of a greater proportion of minor complications (34.8% versus 16.9%, p = 0.021). When specific minor complications were stratified, there was a greater incidence of hypotension requiring intravenous fluids in neonates ≤2.5 kg (6.5% versus 0%, p = 0.015). After controlling for physician performing procedure and risk category, neonates ≤2.5 kg remained at a higher risk for any complication (adjusted odds ratio = 3.2, 95% confidence interval 1.4–7.2, p = 0.005). The percentage of neonates having at least one major complication was not higher in the ≤2.5-kg group (2.2% versus 2.2%). No procedural deaths occurred in either group.

AbstractWe describe aortic root dilatation, severe aortic regurgitation, and pulmonary artery stenosis that were accidentally diagnosed 23 years after the arterial switch operation for transposition of the great arteries in situs inversus. We successfully performed the modified Bentall procedure and pulmonary artery reconstruction. The pathology of the dilated aortic root revealed intimal atherosclerosis and linear necrosis of the tunica media, suggesting the vulnerability of the pulmonary artery to systemic pressure.

AbstractObjectiveNumerous localities have mandated that chain restaurants post nutrition information at the point of purchase. However, some studies suggest that consumers are not highly responsive to menu labelling. The present qualitative study explored influences on full-service restaurant customers’ noticing and using menu labelling.DesignFive focus groups were conducted with thirty-six consumers. A semi-structured script elicited barriers and facilitators to using nutrition information by showing excerpts of real menus from full-service chain restaurants.SettingParticipants were recruited from a full-service restaurant chain in Philadelphia, Pennsylvania, USA, in September 2011.SubjectsFocus group participants were mostly female, African American, with incomes <$US 60 000, mean age 36 years and education 14·5 years. At recruitment, 33 % (n 12) reported changing their order after seeing nutrition information on the menu.ResultsThree themes characterized influences on label use in restaurants: nutrition knowledge, menu design and display, and normative attitudes and behaviours. Barriers to using labels were low prior knowledge of nutrition; displaying nutrition information using codes; low expectations of the nutritional quality of restaurant food; and restaurant discounts, promotions and social influences that overwhelmed interest in nutrition and reinforced disinterest in nutrition. Facilitators were higher prior knowledge of recommended daily intake; spending time reading the menu; having strong prior interest in nutrition/healthy eating; and being with people who reinforced dietary priorities.ConclusionsMenu labelling use may increase if consumers learn a few key recommended dietary reference values, understand basic energy intake/expenditure scenarios and if chain restaurants present nutrition information in a user-friendly way and promote healthier items.
Charles Burney; or, the Philosophical Misfortune of a Liberal Musician
Authors: MAHIET DAMIEN 
Published: February 2013

ABSTRACTThe moral and political propriety of musical pleasure constituted one of Charles Burney's continuous lines of thought from the 1770s to the 1790s. As a public figure, the music historian found himself called upon to state why music matters – in a preface, a dedication or an essay. Like Jean-Jacques Rousseau, Burney read in musical performances symptoms of contemporary society and politics, but, unlike Rousseau, he perceived in modern music signs of civilization's progress. Musical excellence, according to Burney, required both freedom and affluence; thus while Burney rejected absolutist monarchy, he nevertheless praised the achievements of court culture. Indeed, his advocacy of music as an ‘innocent luxury’ reads as an addendum to eighteenth-century disputes on the morality and benefits of luxury. The social implications of this definition of music, however, are problematic: while Burney acknowledged the right of each individual to feel as they please, he also claimed for the music critic the exclusive authority to speak publicly about music. This essay explores these aspects of Burney's political philosophy of music in relation to the works of Rousseau, Montesquieu, Avison, Wollstonecraft and Hume.
Youth, Capitivity and Virtue in the Eighteenth-CenturyKindertruppen
Authors: MUELLER ADELINE 
Published: February 2013

ABSTRACTThis article uses Mozart's unfinished singspielZaide(k336b, 1780) and its source singspielDas Serailto reconsider the eighteenth-centuryKindertruppen: wandering troupes of young singers, actors and dancers who performed in the court and commercial theatres of Europe. These troupes' repertoire often self-consciously addressed the blend of charm and impropriety that lay behind their controversial appeal. I consider the subgenre of seraglio opera – popular with both youth and adult troupes – and in particular the motifs of the audition scene and the captive's lament as metatheatrical commentaries on the cultural politics of operatic spectatorship. When young actors inhabited the fictional seraglio, their display offered compelling corroboration of contemporary discourse about propriety, naturalness and absorption in the theatre, as well as the new sense of urgency regarding the sheltering of youthful virtue.
Optimization of a broadband directional gain microstrip patch antenna for X–Ku band application
Authors: Khare Anubhuti , Nema Rajesh 
Published: February 2013

In this paper, optimization of a microstrip patch antenna is presented. The optimization uses a genetic algorithm in the IE3DTMSimulator. The optimization is done in several steps, first by changing the position of parasitic patches on the top layer, second by placing a feeding patch at the middle layer of geometry, and third by indirect coupling between the top and middle layer patches. Overall, we have performed many possible iterations and found appropriate geometry. From this appropriate geometry we have achieved maximum directional gain (6.2–8.8 dBi) over a 6 GHz bandwidth slot, 38% impedance bandwidth of the X-band and 14.8% impedance bandwidth of the Ku-band. The broadband frequency of operation is demonstrated by single geometry. The geometry of a single probe fed rectangular microstrip antenna incorporating a slot, gap coupled with a parasitic and an active patch on geometry, has been studied. We have investigated the height between active and parasitic patches as 0.0525λ and the height between parasitic patches itself as 0.0525λ. We have investigated the enhancement in maximum directional gain by stacking geometry with one active patch and two parasitic patches of different dimensions. This optimized antenna is used for X-band and Ku-band applications. The hardware validation and simulation results are matched to the proposed design.
Application of embedding dimension estimation to Volterra series-based behavioral modeling and predistortion of wideband RF power amplifier
Authors: Fehri Bilel , Boumaiza Slim 
Published: February 2013

This paper expounds the systematic modeling of the behavior of radio frequency (RF) power amplifiers (PAs) exhibiting nonlinear, dynamic behavior. The approach begins with an analysis of the PA output signal to deduce the minimum embedding parameters required to accurately model its response, particularly the nonlinearity order and memory effects depth. The knowledge of the RF PA is then exploited in limiting the number of kernels consequently addressing the complexity of the Volterra series which has been the key hindrance to its wider practical adoption. In the proposed Volterra series model, performance is assessed and compared to memory polynomial model and dynamic deviation reduction Volterra models when used to linearize different high-power amplifiers driven with wideband signals of bandwidth up to 40 MHz. Significant linearization performance is achieved using a reduced number of kernels.
Drug treatments for schizophrenia: pragmatism in trial design shows lack of progress in drug design
Authors: Cheng F. , Jones P. B. 
Published: February 2013

Aims.The introduction of second generation antipsychotic (SGA) medication over a decade ago led to changes in prescribing practices; these drugs have eclipsed their predecessors as treatments for schizophrenia. However, the metabolic side effects of these newer antipsychotics have been marked and there are increasing concerns as to whether these novel drugs really are superior to their predecessors in terms of the balance between risks and benefits. In this article, we review the literature regarding comparisons between first generation antipsychotic (FGA) and SGA in terms of clinical effectiveness.Methods.Large (n > 150) randomized-controlled trials (RCTs) comparing the effectiveness (efficacy and side effects) of FGA and SGA medications other than clozapine were reviewed, as were meta-analyses that included smaller studies.Results.The superiority in efficacy and reduced extrapyramidal side effects (EPSE) of SGAs is modest, especially when compared with low-dose FGAs. However, the high risk of weight gain and other metabolic disturbances associated with certain SGAs such as olanzapine is markedly higher than the risk with FGAs at the doses used in the trials.Conclusions.The efficacy profiles of various FGAs and SGAs are relatively similar, but their side effects vary between and within classes. Overall, large pragmatic trials of clinical effectiveness indicate that the care used in prescribing and managing drug treatments to ensure tolerability may be more important than the class of drug used.

Published: February 2013

On‐chip temperature compensation (TC) for optical transmitter (Tx) modules is reported. The TC block is integrated in common silicon (Si)‐substrate with the Tx and demonstrates the ability to maintain a constant VCSEL output light power without an additional monitoring photodiode. Designed and fabricated in a 0.13 µm technology, the Tx with a TC block operates at up to 5 Gbit/s. A BER of less than 10− 12 is achieved at a received input power of − 3 dBm, with a 1.3 dBm variation of received power for a temperature increase of 20–100°C at 5 Gbit/s data rate. The percentage error of the temperature compensated Tx output light power is ± 3%. The Tx module consumes a power of 20 mW at 1.3 V, including the TC block.
