AbstractAimsEvaluate duloxetine in the treatment of women with mixed urinary incontinence (MUI).Materials and Methods588 women, 19–85 years old with ≥4 incontinence episodes/week were randomly assigned to duloxetine 80 mg/day (N = 300) or placebo (N = 288). Patients were classified into three symptom subgroups: stress or urge predominant MUI (SPMUI or UPMUI) or balanced MUI (BMUI) based on their responses to the validated Stress/Urge Incontinence Questionnaire. Half the population was randomly assigned to have urodynamics; SPMUI, UPMUI, and BMUI condition diagnoses were based on signs, symptoms, and urodynamic observations. The primary outcome measure was the change in incontinence episode frequency (IEF). Secondary outcome measures included the Incontinence Quality of Life (I‐QOL) scores, the ICI Quality of Life (ICIQ‐SF) score, and the Patient Global Impression of Improvement (PGI‐I) rating.ResultsAt baseline, women with SPMUI averaged 15.9 IEF/week (61% stress), those with UPMUI averaged 13.2 (70% urge), and those with BMUI averaged 16.5 (52% urge). Overall IEF decreases were significantly greater with duloxetine than placebo (median percent reduction 60% vs. 47%, P < 0.001); both UUI and SUI episodes were significantly decreased with duloxetine (median SUI IEF reduction 59% vs. 43%, P = 0.001; UUI IEF reduction 58% vs. 40%, P < 0.001). Duloxetine IEF decreases were significantly greater for patients with SPMUI conditions and symptoms and for those with UPMUI conditions but not symptoms. Significant benefits were also demonstrated with duloxetine for improvements in I‐QOL total score (11.5 points vs. 8.1 points, P = 0.002), all three I‐QOL subscale scores, and for the ICIQ‐SF score (−2.6 vs. −1.7, P = 0.002) as well as for PGI‐I ratings (much/very much better 44.2% vs. 27.3%, P = 0.001).ConclusionDuloxetine demonstrated significant efficacy in this population of women with MUI.

Authors: Pokorska Iwona 
Published: June 2007

AbstractA unified approach for parameter identification of a visco‐poroplastic material model is presented. A repressing powder forging process is analyzed. The numerical solutions for direct and inverse problems have been described. The inverse problem is solved by the use of gradient‐based methods and a sensitivity analysis. Numerical examples of the method proposed are presented, in which one and two parameters of the visco‐poroplastic material model were identified. Copyright © 2007 John Wiley & Sons, Ltd.
Numerical analysis and computational testing of a high accuracy Leray‐deconvolution model of turbulence
Authors: Layton William , Manica Carolina C. , Neda Monika , Rebholz Leo G. 
Published: June 2007

AbstractWe study a computationally attractive algorithm (based on an extrapolated Crank‐Nicolson method) for a recently proposed family of high accuracy turbulence models, the Leray‐deconvolution family. First we prove convergence of the algorithm to the solution of the Navier‐Stokes equations and delineate its (optimal) accuracy. Numerical experiments are presented which confirm the convergence theory. Our 3d experiments also give a careful comparison of various related approaches. They show the combination of the Leray‐deconvolution regularization with the extrapolated Crank‐Nicolson method can be more accurate at higher Reynolds number that the classical extrapolated trapezoidal method of Baker (Report, Harvard University, 1976). We also show the higher order Leray‐deconvolution models (e.g. N = 1,2,3) have greater accuracy than the N = 0 case of the Leray‐α model. Numerical experiments for the 2d step problem are also successfully investigated. Around the critical Reynolds number, the low order models inhibit vortex shedding behind the step. The higher order models, correctly, do not. To estimate the complexity of using Leray‐deconvolution models for turbulent flow simulations we estimate the models' microscale.© 2007 Wiley Periodicals, Inc.

Free admission to museums and monuments: an exploration of some perceptions of the audiences
Authors: Gall‐Ely Marine Le , Urbain Caroline , Bourgeon‐Renault Dominique , Gombault Anne , Petr Christine 
Published: June 2007

Abstract

This paper considers the theme of the audiences' perceptions of free admission in national French museums and monuments. The results show that, from an individual perspective, perceptions of free admission are linked to perceptions of price, money and payment, hence complementing perceptions expressed in a collective perspective (a symbolic, political measure causing either adhesion or rejection). These perspectives are generally put forward by both advocates and opponents of the measure in their discussions. These different visions of free admission have managerial implications for managers of museums and monuments.

Effect of different reaction parameters on the conductivity and dielectric properties of polyaniline synthesized electrochemically and modeling of conductivity against reaction parameters through regression analysis
Authors: Bhadra Sambhu , Singha Nikhil K. , Chattopadhyay Santanu , Khastgir Dipak 
Published: June 2007

AbstractThe polyaniline (PAni) is prepared electrochemically from an aqueous solution of aniline and HCl in a single compartment electrochemical cell. Different PAni samples obtained by varying monomer concentration, acid concentration, applied potential, reaction time, and reaction temperature are subjected to conductivity and dielectric tests. The degree of crystallinity, d‐spacing, interchain separation, and crystallite size are determined form X‐ray analysis, the oxidation state is determined from infrared spectroscopy (FTIR) analysis, and the doping level is estimated from TGA analysis for all the PAni samples synthesized under different conditions. All these structural properties are correlated with electrical properties. The whole result reveals that all the aforementioned reaction parameters affect the structural properties, which in turn affect the electrical properties of PAni. The mathematical model correlations between conductivity and reaction parameters are established from the regression analysis for individual variables as well as for all the variables together. These relationships give the conductivity as an output when we input the value of reaction variables. The output obtained from the model relations found in well agreement with the experimental results under identical conditions. © 2007 Wiley Periodicals, Inc.

Applying Bootstrap method to the types I–II errors in the measurement system
Authors: Wang F. K. , Yang S. W. 
Published: June 2007

AbstractThis paper attempts to evaluate different methods of calculating the type‐I and type‐II errors in the measurement system. Furthermore, we apply the Bootstrap method to construct the confidence intervals for the type‐I and type‐II errors. Also, the proposed method is compared with the generalized inference method. Several factors such as the sample size, the measurement error, the process mean, and the process variation are simulated to validate the performance. The simulation results show that both methods almost have the same performance. In addition, we develop a computer program that can evaluate the error of measurement system without changing information or data. Two case studies of the nano measurement data are used to demonstrate the application. The simulation results indicate that the sample size has an influence for all cases. The type‐I and type‐II errors are decreased when the measurement error is increased. The type‐I and type‐II errors are affected by the measurement error, the process
mean, and the process deviation. The case studies show that the development of nano technology requires the immediate attention of the measurement capability. Copyright © 2007 John Wiley & Sons, Ltd.
Some relationships between gage R&R criteria
Authors: Woodall William H. , Borror Connie M. 
Published: June 2007

AbstractIn this paper, several commonly used gage repeatability and reproducibility (R&R) acceptance criteria are discussed. The number of distinct categories (ndc) is equivalent to an acceptance criterion based on another standard metric, the ratio of the estimated measurement system standard deviation to the estimated overall standard deviation of the measurements. This implies that the criterion based on ndc could be considered redundant. Several acceptance criteria are revisited and compared, including a discussion of more objective measures of capability based on misclassification rates. The relationship between ndc and the discrimination ratio is also given. Copyright © 2007 John Wiley & Sons, Ltd.

Authors: Hosseini Seyed Mohsen , Amiri Mahmood , Najarian Siamak , Dargahi Javad 
Published: June 2007

AbstractBackgroundArtificial tactile sensing is a method in which the existence of tumours in biological tissues can be detected and computerized inverse analyses used to produce ‘forward results’.MethodsThree feed‐forward neural networks (FFNN) have been developed for the estimation of tumour characteristics. Each network provides one of the three parameters of the tumour, i.e. diameter, depth and tumour:tissue stiffness ratio. A resilient back‐propagation (RP) algorithm with a leave‐one‐out (LOO) cross‐validation approach is used for training purposes.ResultsThe proposed inverse approach based on neural networks is a reliable and efficient tool for diagnostic tests in order to accurately estimate the basic parameters of the tumour in the tissue.ConclusionThere is a non‐linear correlation between the tumour characteristics and their effects on the extracted features. In general, reliable estimation of tumour stiffness is obtained when the depth of tumour is small. Copyright © 2007 John Wiley & Sons, Ltd.

Orthogonal array experiment for architecting a system of systems responding to small boat attacks
Authors: Huynh Thomas V. , Kessler Andrew , Oravec Joseph , Wark Shaunnah , Davis Jennifer 
Published: June 2007

AbstractIn this work we solve the problem of architecting a conceptual, near‐term, cost‐effective system of systems (SoS) to respond to small boats used by terrorists to attack maritime commerce traffic and critical shore infrastructures in the United States, by formulating the architecting problem as an assignment problem which is then solved using the orthogonal array experiment. Also known as the Taguchi method in quality control, the orthogonal array experiment is efficient for this class of problems. The optimality of the resulting architecture, called optimal cost‐effective architecture, is validated against a heuristically developed architecture and an optimal effective architecture; the latter is obtained also with the orthogonal array experiment approach. The main purpose of this paper is an exploratory application of the Taguchi method to architecting a system of systems. The principal results of the orthogonal array experiment method reported herein underline this successful exploratory work in architecting a system of systems. This method can be extended to architecting other systems of systems. © 2007 Wiley Periodicals, Inc. Syst Eng 10: 241–259, 2007

Published: June 2007

AbstractThe aim of this article is to provide an up‐to‐date survey of the business environment in Bosnia and Herzegovina that may serve as a guide for doing business in this turbulent country. Our analysis provides a starting point for understanding the demographic, historical, political, economic, and cultural influences that have converged to produce one of the world's most perplexing business environments. We aim to provide the reader with a basic understanding of the political, social, and economic upheaval that has engulfed the country since 1990 and explain how this has impacted the business environment and managerial practices. Furthermore, we explain how managerial and systemic legacies stemming from the communist era from 1945 to 1989, and a range of cultural, political, and historical influences, continue to shape business practices in this dynamic country. © 2007 Wiley Periodicals, Inc.

Published: June 2007

AbstractIraq, a country endowed with enormous resources and the second‐largest oil reserves in the world, is anticipated to regain economic vitality. A new market‐oriented business environment is emerging with promising investment opportunities, as private enterprise is expected to be leading the economic recovery. Most business leaders in Iraq have a positive outlook on the future and welcome opening Iraq to the international business community. A new Iraq would offer enormous opportunities to multinational corporations. Though doing business in Iraq is currently fraught with risk, it should prove very profitable once the country gets hold of its security situation. © 2007 Wiley Periodicals, Inc.
Esophagogastric Cancers Secondary to a Breast Primary Tumor Do Not Require Resection
Authors: Ayantunde A. A. , Agrawal A. , Parsons S. L. , Welch N. T. 
Published: June 2007

AbstractBackgroundBreast cancer metastasis to the gastrointestinal tract (GIT) is rare. When it does occur, the upper GIT is more frequently involved, and lobular infiltrating carcinoma apparently has a greater apparent predilection for the GIT than the ductal type does. This study reviewed the clinicopathological features of esophagogastric secondary tumors from breast cancer.Patients and MethodsPatients with breast cancer metastases to the upper GIT referred to us for treatment of either esophageal or gastric cancers between November 1997 and November 2004 were identified from our database. The medical records of these patients were then reviewed for clinicopathological data and outcome.ResultsNine patients with mean age of 71 (range: 57–90) years had median time of 6.5(2.8–32.8) years between primary breast cancer diagnosis and upper GI metastasis. The sites of metastatic lesions included the lower esophagus (2 patients), gastroesophageal junction (1 patient), gastric body (3 patients), and pylorus (3 patients). Histological typing indicated 7 cases of the lobular form and 2 cases of ductal carcinoma. All but one biopsy specimen were estrogen receptor and CK7 positive. Treatment included hormonal therapy and stent in 3 patients, hormonal therapy alone in 1 patient, chemotherapy alone in 1 patient, chemotherapy and gastrojejunostomy in 1 patient, dilatation and stent in 1 patient, and palliative care only in 2 patients. The median survival following treatment of these metastases was 20 (range: 2.1–96.6) months.ConclusionsThe onset of nonspecific GIT symptoms in patients with a history of breast carcinoma should prompt the clinician to rule out the possibility of upper GIT metastasis even many years after the original breast cancer. The use of systemic therapy for breast cancer may result in longer survival.

Published: June 2007

AbstractObjective: To compare the clinical efficacy of 3 surgical procedures for central types of anterior vaginal wall defect. Methods: A total of 138 patients diagnosed with central types of anterior vaginal wall defect who underwent classic transvaginal repair (n = 72), transvaginal repair with polypropylene mesh (n = 28), and internal repair (n = 38) were followed up for at least 1 year. Results: There were no differences in development of fever, vaginal erosion, detrusor overactivity, and voiding difficulty among the 3 groups, but the incidence of postoperative urinary tract infections was significantly higher in the polypropylene mesh repair group. The difference in preoperative and postoperative hemoglobin levels and wound infection incidence were significantly higher in the internal repair group. Moreover, the recurrence rate of the anterior vaginal wall defect was significantly higher at 1 year in the internal repair group. Conclusion: Transvaginal surgical repair seems to be more efficacious than internal surgical repair for central types of anterior vaginal wall defects.
A methodology for probabilistic predictions of regional climate change from perturbed physics ensembles
Authors: Murphy J.M , Booth B.B.B , Collins M , Harris G.R , Sexton D.M.H , Webb M.J 
Published: June 2007

A methodology is described for probabilistic predictions of future climate. This is based on a set of ensemble simulations of equilibrium and time-dependent changes, carried out by perturbing poorly constrained parameters controlling key physical and biogeochemical processes in the HadCM3 coupled ocean–atmosphere global climate model. These (ongoing) experiments allow quantification of the effects of earth system modelling uncertainties and internal climate variability on feedbacks likely to exert a significant influence on twenty-first century climate at large regional scales. A further ensemble of regional climate simulations at 25 km resolution is being produced for Europe, allowing the specification of probabilistic predictions at spatial scales required for studies of climate impacts. The ensemble simulations are processed using a set of statistical procedures, the centrepiece of which is a Bayesian statistical framework designed for use with complex but imperfect models. This supports the generation of probabilities constrained by a wide range of observational metrics, and also by expert-specified prior distributions defining the model parameter space. The Bayesian framework also accounts for additional uncertainty introduced by structural modelling errors, which are estimated using our ensembles to predict the results of alternative climate models containing different structural assumptions. This facilitates the generation of probabilistic predictions combining information from perturbed physics and multi-model ensemble simulations. The methodology makes extensive use of emulation and scaling techniques trained on climate model results. These are used to sample the equilibrium response to doubled carbon dioxide at any required point in the parameter space of surface and atmospheric processes, to sample time-dependent changes by combining this information with ensembles sampling uncertainties in the transient response of a wider set of earth system processes, and to sample changes at local scales.
The methodology is necessarily dependent on a number of expert choices, which are highlighted throughout the paper.
Creative information seeking

Published: June 2007

PurposeThis is part II of on‐going research, the purpose being to establish a creative information‐seeking model.Design/methodology/approachTwo studies were conducted to examine the subjects' creative information seeking behaviours and the extent to which they exhibited the proposed stages in creative information seeking when accomplishing a directed and an open‐ended information‐seeking task respectively.FindingsFindings seemed to indicate that all the subjects underwent the proposed stages although they seemed to embrace characteristics of these stages in varying degrees. Findings also showed that if subjects performed the proposed stages more iteratively or non‐sequentially, then a greater amount of creativity was needed to accomplish the information‐seeking task.Originality/valueThe paper offers a discussion on the relationships between creativity, complexity of tasks, and levels of expertise in domain knowledge.
The missing link: journal usage metrics
Authors: Rowlands Ian , Nicholas David 
Published: June 2007

PurposeThe aim of this short communication is to contribute to a growing debate about how we can measure the “quality” of journals. More specifically, the paper argues the need for a new range of standardized indicators based on reader (rather than author‐facing) metrics.Design/methodology/approachThis is a thought experiment, outlining the kinds of usage indicators that could be developed alongside the traditional ISI measures of impact, immediacy and obsolescence.FindingsThe time is ripe to develop a set of standardised measures of journal usage that are as easy to understand, and as universally accepted, as ISI's current citation‐based indicators. By linking article publication year to full text downloads, this article argues that very considerable value could be extracted from what, in many cases, is almost uninterpretable data.Practical implicationsIndicators in the form proposed could find a wide variety of applications, from helping librarians to assess the potential value‐for‐money of bundled journal deals, to helping policy‐makers and scholarly communication researchers to better understand the dynamics of knowledge diffusion.Originality/valueThe development of standardized usage factors in the form suggested here would radically shift the centre of gravity in bibliometrics research from the author to the reader. This remains largely unexplored territory.
