Semantic Web Service matchmakers: state of the art and challenges
Authors: Dong Hai , Hussain Farookh Khadeer , Chang Elizabeth 
Published: June 2012

SUMMARYWeb services provide a standard means for the interoperable operations between electronic devices in a network. The mission of Web service discovery is to seek an appropriate Web service for a service requester on the basis of the service descriptions in Web service advertisements and the service requester's requirements. Nevertheless, the standard language used for encoding service descriptions does not have the capacity to specify the capabilities of a Web service, leading to the problem of ambiguity in the service discovery process. This brings up the vision of Semantic Web Services and Semantic Web Service discovery, which make use of the Semantic Web technologies to enrich the semantics of service descriptions for service discovery. Semantic Web Service matchmakers are the programs or frameworks designed to implement the task of Semantic Web Service discovery and have drawn a significant amount of attention from both academia and industry from the start of this century. In this paper, we conduct a survey of the contemporary Semantic Web Service matchmakers in order to obtain an overview of the state of the art in this research area. We summarize six technical dimensions from the past literature and analyze the typical Semantic Web Service matchmakers mostly developed during the past 4 or 5 years in terms of the six dimensions. By means of this analysis, we gain an understanding of the current research and summarize a series of potential issues to that would provide the foundation for future research in this area.Copyright © 2012 John Wiley & Sons, Ltd.
One‐class support vector machines for personalized tag‐based resource classification in social bookmarking systems
Authors: Godoy Daniela 
Published: June 2012

SUMMARYSocial tagging systems allow users to easily create, organize, and share collections of Web resources in a collaborative fashion. Videos, pictures, research papers, and Web pages are shared and annotated in sites such as Del.icio.us, CiteULike, or Flickr, among others. The rising popularity of these systems leads to a constant increase in the number of users actively publishing and annotating resources and, consequently, an exponential growth in the amount of data contained in their folksonomies, the underlying data structure of tagging systems. In turn, the user task of discovering interesting resources becomes more and more difficult and time‐consuming. In this paper, the problem of filtering resources from social tagging systems according to individual user interests using purely tagging data is studied. One‐class support vector machine classification is evaluated as a means to identify relevant information for users based exclusively on positive examples of their information preferences. It is assumed that users express their interest on resources belonging to a folksonomy by assigning tags to them, whereas there is no straightforward method to collect uninterestingness judgments. Filtering interesting resources based on social tags is an important benefit of exploiting the collective knowledge generated by tagging activities of Web communities. In this paper, the results achieved with tag‐based classification are compared with those obtained using more traditional information sources such as the full text of Web pages. Experimental evaluation showed that tag‐based classifiers outperformed those learned using the text of documents as well as other content‐related sources. Moreover, tag‐based classification becomes essential for folksonomies in which no additional content is available because of the nature of resources being stored (e.g., tagging of photos or videos).

Published: June 2012

AbstractBackgroundThe purpose of this study was to evaluate combined autofluorescence (AF) and narrow band imaging (NBI) for detection of mucosal lesions additional to known primary head and neck cancers and to determine impact on management.MethodsPatients with head and neck cancer requiring preoperative screening or posttreatment surveillance had white light (WL), AF and NBI inspection of the head and neck and bronchus. Known primary cancers were not analyzed, only additional lesions. Moderate dysplasia or worse was considered significant.ResultsIn all, 73 patients were recruited. Respectively, there were 24 and 18 additional lesions in the head and neck and bronchus that had significant histopathology. In both regions, AF and NBI were more sensitive than WL for detecting significant dysplasia with NBI demonstrating better specificity than AF (p = .003); 11 of 73 patients (15.1%) had additional findings detected by AF and NBI, which had an impact on management.ConclusionCombined AF and NBI inspection is highly specific at panendoscopy and can influence management. © 2012 Wiley Periodicals, Inc.

Role of excision repair cross‐complementation 1 expression as a prognostic marker for response to radiotherapy in early‐stage laryngeal cancer
Authors: Johung Kimberly , Rewari Amar , Wu Hao , Judson Benjamin , Contessa Joseph N. , Haffty Bruce G. , Decker Roy H. 
Published: June 2012

AbstractBackgroundHigh expression of excision repair cross‐complementation 1 (ERCC1) predicts for resistance to platinum‐based chemotherapy or chemoradiotherapy. We evaluated the prognostic value of ERCC1 expression in a cohort of laryngeal cancer treated with radiotherapy alone.MethodsERCC1 expression was examined by immunohistochemical analysis of tissue microarrays constructed from 123 patients with stages I–II laryngeal squamous cell carcinoma treated with standard radiotherapy.ResultsERCC1 expression did not correlate with clinicopathologic risk factors, local control, or overall survival. At 5 years, local control was 75% versus 71% (p = .78) and overall survival was 68% versus 54% (p = .65), for nonexpressors and expressors of ERCC1, respectively. On multivariate analysis, T classification predicted for local control, and T classification and age predicted for overall survival.ConclusionsERCC1 expression did not predict for radiotherapy resistance or worse survival. Therefore, radiotherapy remains an effective treatment in tumors with high ERCC1 expression. © 2012 Wiley Periodicals, Inc. Head Neck, 2012
Dairy foods and nutrients in relation to risk of ovarian cancer and major histological subtypes

Published: June 2012

AbstractInconsistent results for the role of dairy food intake in relation to ovarian cancer risk may reflect the potential adverse effects of lactose, which has been hypothesized to increase gonadotropin levels, and the beneficial antiproliferative effects of calcium and vitamin D. Using data from the New England case–control study (1,909 cases and 1,989 controls), we examined dairy foods and nutrients in relation to risk of ovarian cancer overall, histological subtypes and rapidly fatal versus less aggressive disease. We used logistic regression and polytomous logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs). In models that were simultaneously adjusted for total (dietary plus supplements) calcium, total vitamin D and lactose, we observed a decreased overall risk of ovarian cancer with high intake of total calcium [Quartile 4 (Q4, >1,319 mg/day) vs. Quartile 1 (Q1, <655 mg/day), OR = 0.62, 95% CI = 0.49–0.79]; the inverse association was strongest for serous borderline and mucinous tumors. High intake of total vitamin D was not associated overall with ovarian cancer risk, but was inversely associated with risk of serous borderline (Q4, >559 IU/day vs. Q1, <164 IU/day, OR = 0.51, 95% CI = 0.34–0.76) and endometrioid tumors (Q4 vs. Q1, OR = 0.55, 95% CI = 0.39–0.80). We found no evidence that lactose intake influenced ovarian cancer risk or that risk varied by tumor aggressiveness in the analyses of intake of dairy foods and nutrients. The overall inverse association with high intake of calcium and the inverse associations of calcium and vitamin D with specific histological subtypes warrant further investigation.
Statin withdrawal after major noncardiac surgery: Risks, consequences, and preventative strategies
Authors: Fallouh Nabil , Chopra Vineet 
Published: June 2012

AbstractBACKGROUND:A growing body of research suggests that statins improve perioperative cardiac outcomes by attenuating inflammation. Conversely, some studies suggest that withdrawal of statins after surgery results in an upsurge of inflammation and adverse cardiac outcomes.METHODS:We performed a literature search using multiple medical databases to examine the basic, clinical, and experimental evidence supporting the existence of a statin withdrawal state. Studies examining outcomes associated with statin withdrawal were narratively synthesized.RESULTS:Published evidence suggests that statin withdrawal is associated with worse cardiac outcomes in a variety of scenarios, including acute coronary syndrome, ischemic stroke, and surgery. Although certain reasons for postoperative statin cessation are difficult to avoid (eg, ileus after surgery), we posit that many perioperative clinicians may be unaware of the importance of statin resumption in a timely fashion. This lack of awareness translates into preventable harm and an opportunity for outcome improvement. We introduce innovative practices through which perioperative practitioners may prevent statin discontinuation.CONCLUSIONS:Ensuring the resumption of statins after surgery should become routine practice for perioperative providers. We highlight knowledge gaps and identify a research agenda aimed at better understanding this practice. Journal of Hospital Medicine 2012; © 2012 Society of Hospital Medicine
Smartphone use during inpatient attending rounds: Prevalence, patterns and potential for distraction
Authors: Katz‐Sidlow Rachel J. , Ludwig Allison , Miller Scott , Sidlow Robert 
Published: June 2012

AbstractBACKGROUND:While there are numerous benefits of smartphone use for physicians, little is known about the negative effects of using these devices in the context of patient care.OBJECTIVE:To assess resident and faculty smartphone use during inpatient attending rounds and its potential as a source of distraction during transfer of clinical information.DESIGN:Cross‐sectional survey.SETTING:University‐affiliated public teaching hospital.PARTICIPANTS:All housestaff and inpatient faculty in the departments of Medicine and Pediatrics.METHODS:Participants were asked about smartphone ownership, usage patterns during attending rounds, and whether team members had ever missed important data during rounds due to distraction from smartphones. Attendings were asked whether policies should be established for smartphone use during rounds.RESULTS:The overall response rate was 73%. Device ownership was prevalent (89% residents, 98% faculty), as was use of smartphones during inpatient rounds (57% residents, 28% attendings). According to self‐reports, smartphones were used during rounds for patient care (85% residents, 48% faculty), reading/responding to personal texts/e‐mails (37% residents, 12% faculty), and other non‐patient care uses (15% residents, 0% faculty). Nineteen percent of residents and 12% of attendings believed they had missed important information because of distraction from smartphones. Residents and faculty agreed that smartphones “can be a serious distraction during attending rounds,” and nearly 80% of faculty believed that smartphone policies should be established.CONCLUSIONS:Smartphone use during attending rounds is prevalent and can distract users during important information transfer. Attendings strongly favored the institution of formal policies governing appropriate smartphone use during inpatient rounds. Journal of Hospital Medicine 2012;. © 2012 Society of Hospital Medicine
Photonic crystal devices: some basics and selected topics
Authors: De La Rue R.M. , Seassal C. 
Published: June 2012

AbstractThis review article is concerned with basic aspects and some selected topics in photonic crystal (PhC) devices. It starts with a significantly historical aspect of basic principles for photonic crystals that it is hoped will help the reader to develop a critical appreciation of the research literature. It continues by describing topics such as PhC beamsplitters, slow‐light structures, micro‐/nanoresonators, coupled resonator optical waveguides (CROWs) and PhC‐based semiconductor lasers. Emphasis is placed on both the conceptual and the practical matters that need to be addressed in order to fulfill the tasks of designing and realizing devices that exploit photonic crystal principles. The review also addresses some of the problems encountered in the fabrication of photonic crystal devices using the planar technologies of integrated photonics, which are those that are most likely to be used in future commercial production.
A partitioning approach for H∞ control of singular time‐delay systems
Authors: Kchaou Mourad , Tadeo Fernando , Chaabane Mohamed 
Published: June 2012

SUMMARYThis paper presents a new approach for delay‐dependent H∞ stability analysis and control synthesis for singular systems with delay. By constructing an augmented Lyapunov–Krasovskii functional with a triple‐integral term, and using the partitioning technique, a bounded real lemma is presented to ensure the singular state‐delay system to be regular, impulse free and stable with γ‐disturbance rejection. The proposed result leads to significant performance improvement in system analysis and synthesis. Based on the criterion obtained, a homotopy‐based iterative LMI algorithm is developed to design a static output feedback controller. The feasibility and the effectiveness of theoretical developments are illustrated through numerical examples.Copyright © 2012 John Wiley & Sons, Ltd.
TRANSLATING DEVELOPMENT AID INTO CITY MANAGEMENT: THE BARRIO ACAHUALINCA INTEGRATED DEVELOPMENT PROGRAMME IN MANAGUA, NICARAGUA
Authors: Zapata Campos María José , Zapata Patrik 
Published: June 2012

SUMMARYThis article seeks to understand how development aid is translated into city management practice in the global South and the implications of this for the power dynamics between municipal governments and international aid agencies. The study examines La Chureca, the rubbish dump and slum of Managua, Nicaragua, and its regeneration programme, the Barrio Acahualinca Integrated Development Programme. In the article, we explore the formulation and initial implementation of the Programme in terms of the construction of an action net in which, by a chain of translations, the Programme was transformed from an aid programme managed by international aid organisations into the management practice of the city of Managua. Despite the silent infiltration of important issues brought to the municipal political agenda by the development aid programme, small acts of defiance and resistance were also enacted by local actors who twisted the Programme to fit local needs.

Feasibility of a tandem autologous peripheral blood stem cell transplant regimen for high risk neuroblastoma in a cooperative group setting: A Pediatric Oncology Group study: A Report from the Children's Oncology Group
Authors: Granger Meaghan , Grupp Stephan A. , Kletzel Morris , Kretschmar Cynthia , Naranjo Arlene , London Wendy B. , Diller Lisa 
Published: June 2012

AbstractBackgroundThe Pediatric Oncology Group performed a pilot study to assess the feasibility of tandem high dose chemotherapy (HDC) with stem cell rescue (HDC/SCR). We report here the results of this single arm trial of induction chemotherapy, local control measures (surgery and local radiation), and tandem HDC/SCR.ProcedurePatients with high risk neuroblastoma (NBL) underwent five cycles of induction chemotherapy and resection of primary tumors. Peripheral blood stem cells (PBSC) were collected after Course 3 without exvivo manipulation. Myeloablative chemotherapy was performed in rapid sequence after induction chemotherapy and surgery. The ability of patients to complete both cycles of HDC/SCR was a primary endpoint. Transplant‐related toxicity, progression‐free survival (PFS) and overall survival (OS) were recorded.ResultsA total of 33 patients were enrolled. Twenty‐two patients completed at least one HDC/SCR procedure and 17 patients completed both. Only one patient had insufficient stem cells collected for both transplants. There was one transplant‐related death; engraftment was rapid and toxicity was as expected. The PFS of the 33 patients treated on this study is 24.2% ± 7.5% and OS is 36.4% ± 8.4% at 5 years. For patients who received at least one transplant PFS is 36.4% ± 11.0% and OS is 45.5% ± 11.2% at 5 years.ConclusionsThe treatment of high risk NBL with tandem HDC/SCR is feasible in terms of transplant‐related mortality and the ability to collect adequate PBSC for two transplants. The outcomes from this intensified treatment have been used to design a Children's Oncology Group Phase III study testing the efficacy of tandem HDC/SCR.

Published: June 2012

AbstractBackgroundCisplatin may cause permanent cochlear damage by changing cochlear frequency selectivity and can lead to irreversible sensorineural hearing loss. High‐frequency audiometry (HFA) is able to assess hearing frequencies above 8,000 Hz; hence, it has been considered a high‐quality method to monitor and diagnose early and asymptomatic signs of ototoxicity in patients receiving cisplatin.ProcedureForty‐two pediatric patients were evaluated for hearing loss induced by cisplatin utilizing HFA, and its diagnostic efficacy was compared to that of standard pure‐tone audiometry and distortion‐product otoacoustic emissions (DPOAEs). The patient population consisted of those who signed an informed consent form and had received cisplatin chemotherapy between 1991 and 2008 at the Hospital de Clínicas de Porto Alegre Pediatric Unit, Brazil.ResultsForty‐two patients were evaluated. The median age at study assessment was 14.5 years (range 4–37 years). Hearing loss was detected in 24 patients (57%) at conventional frequencies. Alterations of DPOAEs were found in 64% of evaluated patients and hearing loss was observed in 36 patients (86%) when high‐frequency test was added. The mean cisplatin dose was significantly higher (P = 0.046) for patients with hearing impairment at conventional frequencies.ConclusionThe results suggest that HFA is more effective than pure‐tone audiometry and DPOAEs in detecting hearing loss, particularly at higher frequencies. It may be a useful tool for testing new otoprotective agents, beside serving as an early diagnostic method for detecting hearing impairment.

AbstractBackgroundOf 4,706 peripheral neuroblastic tumors (pNTs) registered on the Children's Cancer Group and Children's Oncology Group Neuroblastoma Study between 1989 and 2010, 51 cases (1.1%) had genotype–phenotype discordance characterized by MYCN amplification (indicating poor prognosis) and Favorable Histology (indicating better prognosis).ProcedureTo distinguish prognostic subgroups in the genotype–phenotype discordant pNTs, two subgroups, “conventional” and “bull's eye,” were identified based on the nuclear morphology. The “conventional” tumors (35 cases) included: Neuroblastoma, poorly differentiated subtype (NB‐PD, 26 cases) with “salt‐and‐pepper” nuclei; neuroblastoma, differentiating subtype (4 cases); ganglioneuroblastoma, intermixed (3 cases); and ganglioneuroma, maturing subtype (2 cases). The “bull's eye” tumors included NB‐PD with prominent nucleoli (16 cases). Clinicopathologic characteristics of these two subgroups were analyzed. N‐myc protein expression was tested immunohistochemically on available tumors.ResultsNo significant difference was found between these two subgroups in the distribution of prognostic factors such as age at diagnosis, clinical stage, histopathology category/subtype, mitosis‐karyorrhexis index, ploidy, 1p LOH, and unbalanced 11q LOH. However, prognosis of the patients with “conventional” tumors (5‐year EFS 85.7 ± 12.2%; OS 89.3 ± 10.3%) was significantly better than those with “bull's eye” tumors (EFS 31.3 ± 13.0%; OS 42.9 ± 16.2%; P = 0.0010 and 0.0008, respectively). Immunohistochemically all (11/11) tested “conventional” tumors were negative, and 10/11 tested “bull's eye” tumors were positive for N‐myc protein expression.ConclusionsBased on the presence or absence of prominent nucleoli (the putative site of RNA synthesis/accumulation leading to N‐myc protein expression), two prognostic subgroups, “conventional” with a better prognosis and “bull's eye” with a poor prognosis, were distinguished among the genotype–phenotype discordant pNTs.
