Authors: Burns Anthony S. , Delparte Jude J. , Ballantyne Elena C. , Boschen Kathryn A. 
Published: May 2013

ObjectiveTo assess efficacy of an interdisciplinary pain program adapted for persons with spinal cord injury (SCI) and chronic pain.DesignProspective cohort.SettingUniversity‐affiliated rehabilitation hospital.ParticipantsTwenty‐two persons with traumatic or nontraumatic SCI and chronic pain of at least 6 months’ duration.MethodsSubjects participated in an interdisciplinary pain program consisting of biweekly group sessions for 10 consecutive weeks. Sessions incorporated patient education on chronic pain and associated pain mechanisms, cognitive behavioral therapy, self‐management strategies (eg, energy conservation, ergonomics, goal setting, stress management, anger management, and coping skills), group discussions and activities, and either exercise or guided relaxation at the end of each session.Main Outcome MeasuresMultidimensional Pain Inventory SCI, Coping Inventory of Stressful Situations, Pain Stages of Change Questionnaire, and Life Satisfaction Questionnaire.ResultsAfter participation in an interdisciplinary pain program, persons with SCI and chronic neuropathic pain demonstrated increased involvement in learning and maintenance of coping strategies for chronic pain. Participation also led to less pain interference in daily life and a greater sense of control over one's life.ConclusionsParticipation in an interdisciplinary pain program does not reduce pain severity, but it can help persons with SCI and chronic neuropathic pain cope with pain, lessen interference of pain, and improve their sense of control.
An Analysis of Hiker Preparedness: A Survey of Hiker Habits in New Hampshire
Authors: Mason Ryan C. , Suner Selim , Williams Kenneth A. 
Published: May 2013

Objective Describe hiking habits in a heavily used wilderness area to better target injury prevention and reduce search-and-rescue events. Methods A cross-sectional, convenience survey was conducted at 3 trailheads in the White Mountain National Forest of New Hampshire during summer 2011. The study group consisted of hikers who consented to a questionnaire before their trip that assessed demographics, experience, hiking gear, pretrip planning, and communication devices. Results A total of 199 hikers were surveyed. The most common age group was 20 to 29 years at 29.2% (n = 195). The most common hike was less than 12 hours at 78.5% (n = 191). All 10 items deemed essential were carried by 17.8% (n = 197) of hikers. The most common omission reason was “short trip” at 32.2% (n = 162). Defined as greater than 7 items, the 50- to 59-year-old age group was the most prepared at 56.9% (n = 51). Hiker preparedness increased with experience and fitness levels. Hikers planning trips of less than 12 hours were less prepared compared with hikers planning longer trips, at 39.3% (n = 150) and 48.8% (n = 41), respectively. GPS devices were carried by 122 of 193 hikers. Phone GPS users were less prepared than GPS-only device users at 35.8% (34 of 95) and 55.6% (15 of 27), respectively. Conclusions One factor that may help reduce rescues is better-prepared individuals able to avoid emergency medical services activation. Most neglect of preparation results from hikers perceiving short trips as less risky. The groups most often underprepared tend to be younger, less fit, and inexperienced. Therefore, education should target younger groups and stress that all hikes, regardless of duration, carry an inherent risk.
Self-similar vortex-induced vibrations of a hanging string
Authors: Grouthier C. , Michelin S. , Modarres-Sadeghi Y. , de Langre E. 
Published: May 2013

AbstractAn experimental analysis of the vortex-induced vibrations of a hanging string with variable tension along its length is presented in this paper. It is shown that standing waves develop along the hanging string. First, the evolution of the Strouhal number $\mathit{St}$ with the Reynolds number $\mathit{Re}$ follows a trend similar to what is observed for a circular cylinder in a flow for relatively low Reynolds numbers ($32\lt \mathit{Re}\lt 700$). Second, the extracted mode shapes are self-similar: a rescaling of the spanwise coordinate by a self-similarity coefficient allows all of them to collapse onto a unique function. The self-similar behaviour of the spatial distribution of the vibrations along the hanging string is then explained theoretically by performing a linear stability analysis of an adapted wake-oscillator model. This linear stability analysis finally provides an accurate description of the mode shapes and of the evolution of the self-similarity coefficient with the flow speed.
Regulatory Accountability in the Nigerian Telecommunications Sector
Authors: Opata Chukwudiebube Bede Abraham 
Published: May 2013

AbstractThis article addresses the issue of how the Nigerian Communications Commission, which is responsible for the independent regulation of the Nigerian telecommunications sector, could be made accountable. The need for accountability is relevant given the local context of pervasive corruption and lower expectations of accountability when compared with more mature democracies. The accountability question is analysed in terms of the traditional public accountability mechanisms of executive supervision, legislative oversight and judicial review, highlighting the limits and challenges facing the application of each traditional accountability mechanism to the commission. An extended notion of accountability, specifically the adoption of fair procedures in decision making and accountability to the public at large, are presented as feasibly complementary to traditional accountability mechanisms. Finally the article proposes an amendment to the pre-action conditions to judicial review to facilitate greater accountability.
Governance through Trading: Institutional Swing Trades and Subsequent Firm Performance
Authors: Gallagher David R. , Gardner Peter A. , Swan Peter L. 
Published: May 2013

AbstractUsing unique daily fund-manager trade data, we examine the role of institutional trading in influencing firm performance. We show that short-horizon informed trading by multiple institutional investors effectively disciplines corporate management. Our focus is on short-term “swing” trades, sequences with three phases (e.g., buy-sell-buy). We find swing trades increase stock price informativeness, are profitable after costs, and improve market efficiency. This increase in stock price informativeness is associated with subsequent firm outperformance. Trades are most beneficial with optimal stock holdings that reflect the information acquisition incentives of investors as well as liquidity costs.
Alien invasions: the British Musicians' Union and foreign musicians
Authors: Cloonan Martin , Brennan Matt 
Published: May 2013

AbstractThis article examines the policies of the British Musicians' Union towards the employment of musicians who were not UK citizens in the period from the 1920s to the 1950s, with particular emphasis on an alleged ban on American musicians entering the country. Drawing on a number of hitherto largely ignored and/or unavailable sources, it argues that many previous accounts of these policies have simplified a more complex picture. We illustrate that complexity and suggest that the issues surrounding the ban are ones which continue to resonate.
Unpacking the gift: negotiating property and custody in archival hardcore blogs
Authors: Heuman Josh 
Published: May 2013

AbstractHow is music appropriated and recirculated on the web, across different claims to authority over its movement? Complicating broad accounts of online ‘piracy’ or ‘sharing’, this paper explores rules of appropriation and recirculation in the field of archival hardcore blogging, in close readings of blogs that try to reconstruct a system of regulating principles and regulated practices. In relations among themselves, bloggers claim (and quarrel over) a non-proprietary ‘custodial’ authority over the music they post, which supports a range of privileges from attribution to exclusivity. Relations between bloggers and property-holders reveal intricate entanglements of different forms of authority (rather than straightforward oppositions between discrete logics of gift and commodity) – in which bands and labels might appeal to subcultural credibility in the same breath as legal copyright. While drawing on concepts of norm and gift that emphasise and valorise the sociality of appropriation, this paper insists on the ambivalence and contestation across different practices of appropriation, and between practices of appropriation and property – recovering an intricate interrelation among the legal, economic and social lives of musical works.
What type of patients with lesions of the pancreas and spine are suitable candidates for treatment with the CyberKnife robotic radiosurgical system?
Authors: McCaighy Stuart 
Published: May 2013

AbstractMaterials & methodsA systematic literature review was conducted to critically examine patient selection for patients undergoing stereotactic body radiotherapy (SBRT) to the spine and pancreas on the CyberKnife robotic radiosurgical system (CK). Online databases were searched and data was collected and ranked using a system from the Scottish Intercollegiate Guideline Network. The quality of the evidence analysed was insufficient to generate universal recommendations. However, the conclusions reached do help to demonstrate the safety and efficacy of CK treatment to both pancreatic and spinal patients.ResultsExcellent local control rates and minimal acute toxicity were reported within the spinal literature with uncertainties remaining with regard to the precise tolerance of the spinal cord and the reliability of current toxicity prediction methods. For pancreatic patients prognosis remains dismal due to the tendency for patients to present with advanced or inoperable disease. Combinations of CK SBRT and Gemcitabine chemotherapy are given though regimes vary and overall survival is not extended due to the rapid onset of distant metastases. New chemotherapy agents are required as well as better means of predicting response to treatment.ConclusionNo randomised controlled trials or meta-analyses were identified in the review and these are required in order to generate universal guidelines
Implication, Quotation, and Coltrane in Selected Works By David N. Baker
Authors: MAXILE HORACE J. 
Published: May 2013

AbstractThis article explores composer David N. Baker's use of elements of jazz and vernacular music to articulate formal structures and suggest extramusical commentaries in his concert works, with particular focus on the Sonata for Cello and Piano and the Sonata I for Piano. Themes of homage to and respect for jazz saxophonist John Coltrane resonate through these works. Various features bring the jazz legend to mind, but Baker's compelling play with implication and quotation provides fertile ground for studying musical signification and the use of vernacular emblems within Western compositional structures and the concert music of African American composers. Conventional analytical methods are combined with readings of referential symbols to work toward interpretations that address both structural and expressive domains. This approach allows discussions of compositional techniques to intersect with cultural and philosophical considerations. By addressing issues of musical structure and expressivity, this article seeks to move beyond commonplace surface-level descriptions of black vernacular emblems in the concert music of African American composers.
“The World is His Song”: Paul Robeson's 1958 Carnegie Hall Concerts and the Cosmopolitan Imagination
Authors: OLWAGE GRANT 
Published: May 2013

AbstractPaul Robeson's celebrated comeback recitals at Carnegie Hall in 1958 marked the singer's return to the world's concert stages after his ban for much of the 1950s. The recitals, this article argues, can be understood as a presentation of cosmopolitan thinking and action, of a certain way of being in and interacting with the world, and also a mid-century critique of American nationalist politics. As such, the article is an elaboration of scholarship that has considered aspects of internationalism in Robeson's discourse and (musical) practice. Drawing on the insights of the new or critical cosmopolitanism, a diverse and loose body of theory that has gained currency since the 1990s, the essay thinks through Robeson's Carnegie Hall events in terms of the practices of the concert hall recital, specifically programming, suggesting what it might mean to be a cosmopolitan singer in a specific historical moment.
The Politics of New Atheism
Authors: Schulzke Marcus 
Published: May 2013

AbstractThis article discusses the political implications of the new atheism movement that has been popularized by writers such as Richard Dawkins, Christopher Hitchens, and Sam Harris. New atheism is largely defined by its political goals, yet it has received relatively little attention from political theorists. To the extent that scholars have commented on new atheists' political thought, they have generally misinterpreted it and presented it as being intolerant. This article will argue that new atheists' attack on religion is largely motivated by their desire to defend a liberal view of politics and liberal values.
IP3R2 levels dictate the apoptotic sensitivity of diffuse large B-cell lymphoma cells to an IP3R-derived peptide targeting the BH4 domain of Bcl-2

AbstractDisrupting inositol 1,4,5-trisphosphate (IP3) receptor (IP3R)/B-cell lymphoma 2 (Bcl-2) complexes using a cell-permeable peptide (stabilized TAT-fused IP3R-derived peptide (TAT-IDPS)) that selectively targets the BH4 domain of Bcl-2 but not that of B-cell lymphoma 2-extra large (Bcl-Xl) potentiated pro-apoptotic Ca2+ signaling in chronic lymphocytic leukemia cells. However, the molecular mechanisms rendering cancer cells but not normal cells particularly sensitive to disrupting IP3R/Bcl-2 complexes are poorly understood. Therefore, we studied the effect of TAT-IDPS in a more heterogeneous Bcl-2-dependent cancer model using a set of ‘primed to death’ diffuse large B-cell lymphoma (DL-BCL) cell lines containing elevated Bcl-2 levels. We discovered a large heterogeneity in the apoptotic responses of these cells to TAT-IDPS with SU-DHL-4 being most sensitive and OCI-LY-1 being most resistant. This sensitivity strongly correlated with the ability of TAT-IDPS to promote IP3R-mediated Ca2+ release. Although total IP3R-expression levels were very similar among SU-DHL-4 and OCI-LY-1, we discovered that the IP3R2-protein level was the highest for SU-DHL-4 and the lowest for OCI-LY-1. Strikingly, TAT-IDPS-induced Ca2+ rise and apoptosis in the different DL-BCL cell lines strongly correlated with their IP3R2-protein level, but not with IP3R1-, IP3R3- or total IP3R-expression levels. Inhibiting or knocking down IP3R2 activity in SU-DHL-4-reduced TAT-IDPS-induced apoptosis, which is compatible with its ability to dissociate Bcl-2 from IP3R2 and to promote IP3-induced pro-apoptotic Ca2+ signaling. Thus, certain chronically activated B-cell lymphoma cells are addicted to high Bcl-2 levels for their survival not only to neutralize pro-apoptotic Bcl-2-family members but also to suppress IP3R hyperactivity. In particular, cancer cells expressing high levels of IP3R2 are addicted to IP3R/Bcl-2 complex formation and disruption of these complexes using peptide tools results in pro-apoptotic Ca2+ signaling and cell death.

Published: May 2013

Abstract
The recent development of metaproteomics has enabled the direct identification and quantification of expressed proteins from microbial communities in situ, without the need for microbial enrichment. This became possible by (1) significant increases in quality and quantity of metagenome data and by improvements of (2) accuracy and (3) sensitivity of modern mass spectrometers (MS). The identification of physiologically relevant enzymes can help to understand the role of specific species within a community or an ecological niche. Beside identification, relative and absolute quantitation is also crucial. We will review label-free and label-based methods of quantitation in MS-based proteome analysis and the contribution of quantitative proteome data to microbial ecology. Additionally, approaches of protein-based stable isotope probing (protein-SIP) for deciphering community structures are reviewed. Information on the species-specific metabolic activity can be obtained when substrates or nutrients are labeled with stable isotopes in a protein-SIP approach. The stable isotopes (13C, 15N, 36S) are incorporated into proteins and the rate of incorporation can be used for assessing the metabolic activity of the corresponding species. We will focus on the relevance of the metabolic and phylogenetic information retrieved with protein-SIP studies and for detecting and quantifying the carbon flux within microbial consortia. Furthermore, the combination of protein-SIP with established tools in microbial ecology such as other stable isotope probing techniques are discussed.
Dysbiosis in inflammatory bowel diseases: the oxygen hypothesis
Authors: Rigottier-Gois Lionel 
Published: May 2013

Abstract
The healthy intestine is characterized by a low level of oxygen and by the presence of large bacterial communities of obligate anaerobes. Dysbiosis of the gut microbiota has been reported in patients suffering from inflammatory bowel diseases (IBDs), but the mechanisms causing this imbalance remain unknown. Observations have included a decrease in obligate anaerobes of the phylum Firmicutes and an increase in facultative anaerobes, including members of the family Enterobacteriaceae. The shift of bacterial communities from obligate to facultative anaerobes strongly suggests a disruption in anaerobiosis and points to a role for oxygen in intestinal dysbiosis. Proposals to evaluate this hypothesis of a role for oxygen in IBD dysbiosis are provided. If this hypothesis is confirmed, decreasing oxygen in the intestine could open novel means to rebalance the microbiota and could provide novel preventative or therapeutic strategies for IBD patients in whom current treatments are ineffective.

Authors: Boscaino Valeria , Pellitteri Filippo , Rosa La , Capponi Giuseppe 
Published: May 2013

In this study, the authors present a 5 W wireless battery charger for handheld devices. Efficiency‐related issues are addressed. A power receiver architecture which improves power conversion efficiency is proposed. Design hints are provided for further applications. Comparison with a conventional architecture is provided as well. Laboratory prototypes of both the proposed and the conventional architectures have been realised. Both prototypes are tested by using the same power transmitter to perform a valuable comparison. As shown by the experimental results, in the receiver side power conversion efficiency is increased up to 99% thanks to the proposed solution.
Implementation of a soft switching DC/DC converter without reverse recovery loss for rectifier diodes
Authors: Lin Bor‐Ren , Jhong Jian‐Yo 
Published: May 2013

This study presents an interleaved soft switching converter to achieve ripple current reduction, zero‐voltage switching (ZVS) turn‐on for MOSFETs and zero‐current switching (ZCS) turn‐off for fast recovery diodes. Active snubber circuit is used in the proposed circuit to absorb the energy stored in the leakage inductor and to achieve ZVS turn‐on for power switches. The resonant tank composed of the leakage inductor and the resonant capacitor at the secondary side is used to achieve ZCS turn‐off for all rectifier diodes. The reverse recovery loss on rectifier diodes can be eliminated. Thus, the low‐cost fast recovery diodes can be used at the secondary side. The interleaved pulse‐width modulation scheme is used to control two converter cells in order to achieve load sharing and input ripple current reduction. Experiments with a 400 W prototype, verifying the effectiveness of the proposed converter, are described.

Published: May 2013

Abstract
Acoustic telemetry has become a leading tool for monitoring the movements of and habitat use by many sturgeon species worldwide; however, procedures for internal tagging of small juvenile sturgeon (&lt;55 cm TL) are lacking. We examined effects of implantation technique on growth, tag retention, and survival of juvenile (&lt;55 cm) Shortnose Sturgeon Acipenser brevirostrum and Atlantic Sturgeon A. oxyrinchus by using dummy acoustic tags. Two implantation techniques were used: (1) anchoring the tag to the wall of the peritoneal cavity and (2) no internal anchoring of the tag. These treatment groups were compared with two control groups: fish that received anesthetic only and fish that received anesthetic and an incision. Retention rate was significantly higher for anchored tags (88%) than for nonanchored tags (25%) in Shortnose Sturgeon juveniles, while Atlantic Sturgeon juveniles retained 100% of tags regardless of treatment. Nonanchored tags that were lost during the second week were expelled through the incision site, whereas later tag expulsions (during weeks 7 and 8) occurred through the anus. There was no significant difference in absolute growth and specific growth rates between the treatment groups throughout the 8-week study for either species. Growth of both species was significantly lower in the first week after surgery but increased and remained constant for the remainder of the experiment. Use of nonanchored tags significantly increased incision healing times for both species; however, Atlantic Sturgeon healed significantly faster (35 d) than Shortnose Sturgeon (42 d). No mortality occurred in any of the treatment groups. Results of this study suggest that juvenile Shortnose Sturgeon and Atlantic Sturgeon can undergo internal tag implantation resulting in long retention times with largely unaffected growth and no mortality.
