A novel Multi‐objective Fuzzy Adaptive Chaotic PSO algorithm for Optimal Operation Management of distribution network with regard to fuel cell power plants

A new Multi-objective Fuzzy Adaptive Chaotic particle swarm optimization (MFACPSO) evolutionary algorithm for the Multi-objective daily Optimal Operation Management (MOOM) problem with regard to fuel cell power plants (FCPPs) in distribution system is presented in this paper. The purposes of the MOOM problem are to minimize the total electrical energy losses, the total electrical energy cost, and the total pollutant emission produced by sources. Conventional algorithms for solving the multi-objective optimization problems convert the multiple objectives into a single objective using a vector of the user-predefined weights. This conversion has several defects. For instance, the final solution of the algorithms greatly depends on the values of the weights and it also loses some information in the conversion and this strategy is not expected to provide a robust solution. The proposed algorithm maintains a finite-sized repository of non-dominated solutions which gets iteratively updated in the presence of new solutions. Since the objective functions are non-commensurable, a fuzzy clustering technique is used to control the size of the repository within the limits. The proposed algorithm is tested on two distribution test feeders and the results demonstrate the capabilities of the proposed approach to generate a set of well-distributed Pareto-optimal non-dominated solutions of the MOOM problem. The comparison with the different reported techniques demonstrates the superiority of the proposed MFACPSO in terms of the diversity of the Pareto-optimal solutions obtained. In addition, the results confirm the potential of the proposed technique to solve the MOOM problem and produce high-quality non-dominated solutions. Copyright © 2010 John Wiley & Sons, Ltd.
A Data-Driven Approach to Measure Web Site Navigability

Web site navigability refers to the degree to which a visitor can follow a Web site's hyperlink structure to successfully find information with efficiency and ease. In this study, we take a data-driven approach to measure Web site navigability using Web data readily available in organizations. Guided by information foraging and information-processing theories, we identify fundamental navigability dimensions that should be emphasized in metric development. Accordingly, we propose three data-driven metrics—namely, power, efficiency, and directness—that consider Web structure, usage, and content data to measure a Web site's navigability. We also develop a Web mining-based method that processes Web data to enable the calculation of the proposed metrics. We further implement a prototype system based on the Web mining-based method and use it to assess the navigability of two sizable, real-world Web sites with the metrics. To examine the analysis results by the metrics, we perform an evaluation study that involves these two sites and 248 voluntary participants. The evaluation results show that user performance and assessments are consistent with the analysis results revealed by our metrics. Our study demonstrates the viability and practical value of data-driven metrics for measuring Web site navigability, which can be used for evaluative, diagnostic, or predictive purposes.
Exploring Foreign Tourists’ Image of Tanzania: A Factorial Analysis Approach

Abstract In the last decade, the economy of African continent and Tanzania in particular has witnessed a business boom of the tourism sector. While the sector has continued to grow and become a dependable source of direct and indirect employment to youths in urban and rural areas, the sector has been awash with challenges. These challenges include terrorism attacks, energy crises and poor infrastructure. However, the impact of these challenges on the image of Tanzania as a tourist destination has not received the deserved attention. This study explores the perception of visitors towards Tanzania as a tourist destination after they have completed their tourist visit. This study employs factor analysis technique to explore country destination image. Questionnaires were administered to visitors at some of the tourists’ hotels and Julius Kamabarage Nyerere International Airport (as a major exit point) in the country. Frontline employees, various tourist sites and access to services emerged to be strong tourist destination image factors. This implies that the efforts of marketing tourism destination should focus on promoting all the sites the country has.
Plasma homocysteine and vitamin B12 serum levels, red blood cell folate concentrations, C677T methylenetetrahydrofolate reductase gene mutation and risk of recurrent miscarriage: a case-control study in Spain

Abstract Background: Hyperhomocysteinemia and methylenetetrahydrofolate reductase (MTHFR) gene mutation have been postulated as a possible cause of recurrent miscarriage (RM). There is a wide variation in the prevalence of MTHFR polymorphisms and homocysteine (Hcy) plasma levels among populations around the world. The present study was undertaken to investigate the possible association between hyperhomocysteinemia and its causative genetic or acquired factors and RM in Catalonia, a Mediterranean region in Spain. Methods: Sixty consecutive patients with ≥3 unexplained RM and 30 healthy control women having at least one child but no previous miscarriage were included. Plasma Hcy levels, MTHFR gene mutation, red blood cell (RBC) folate and vitamin B12 serum levels were measured in all subjects. Results: No significant differences were observed neither in plasma Hcy levels, RBC folate and vitamin B12 serum levels nor in the prevalence of homozygous and heterozygous MTHFR gene mutation between the two groups studied. Conclusions: In the present study RM is not associated with hyperhomocysteinemia, and/or the MTHFR gene mutation.
Assessment of Water Rights and Irrigation Pricing Reforms in Heihe River Basin in China

The purpose of this paper is to understand the progress of water rights and irrigation pricing reform in Heihe River Basin (HRB) and their influence on irrigation application. The data came from a village and household level survey conducted in 2009 and 2014 in five counties in Zhangye City, HRB. The main component of reforming water rights was issuing water certificates to individual farmers. However, the share of villages that have done so dropped from 70% in 2004 to 28% in 2014. Water pricing reform raised the price of water. For the pricing of surface water, which consists of an area-based fee and a volumetric price, the volumetric price was increased. Econometric results show that amending water rights substantially reduced irrigation application in the early stage of reform (by 2009) but not in the later phase (by 2014). In contrast, higher water prices lowered irrigation applications significantly at both the early and later stages. Further analysis indicates that due to ineffective implementation, high cost of implementation due to large number of farmers, variations in water supply from year to year, and small farm sizes, little benefit is gained from trading. All of these factors played a role in the failure of water rights reforms.
European Guideline on HIV testing

Testing for HIV is one of the cornerstones in the fight against HIV spread. The 2014 European Guideline on HIV Testing provides advice on testing for HIV infection in individuals aged 16 years and older who present to sexually transmitted infection, genito-urinary or dermato-venereology clinics across Europe. It may also be applied in other clinical settings where HIV testing is required, particularly in primary care settings. The aim of the guideline is to provide practical guidance to clinicians and laboratories that within these settings undertake HIV testing, and to indicate standards for best
Smart manufacturing and supply chain management

Within the ongoing fourth industrial revolution, smart manufacturing will plays critical role in national level for the growth of the national economy, but also firm level for the sustainable development of the manufacturing activities and the whole supply chain. This paper aims to explore the influences of smart manufacturing to supply chain management, and based on broad literature review this paper also develops several propositions for further explore insights of improving supply chain performance under the context of smart manufacturing.
Pharmacological management of chronic neuropathic pain: Revised consensus statement from the Canadian Pain Society

Neuropathic pain is defined as a lesion or disease of the somatosensory system, and may involve the central or peripheral nervous systems. Treatment of neuropathic pain is a challenge for clinicians involved in affected patients' care. In 2007, the first guidelines for the treatment of neuropathic pain in the Canadian context were produced by the Canadian Pain Society. This update to these guidelines incorporates new evidence published since the first guidelines were released.
Genital Cytomegalovirus Replication Predicts Syphilis Acquisition among HIV-1 Infected Men Who Have Sex with Men

Objective Sexually transmitted infections (STI) are common among HIV-infected men who have sex with men (MSM). While behavioral factors are important in STI acquisition, other biological factors such as immune modulation due to chronic viral infection may further predispose to STI acquisition. Design Post Hoc analysis including data collected over 12 months of follow-up from 131 HIV-infected MSM receiving antiretroviral therapy and screened for incident bacterial STI every 3 months. Methods Genital secretions collected at baseline were used to measure herpesvirus replication and inflammatory cytokines. Baseline predictors of STI were determined using survival analysis of time to incident STI. Results All participants were seropositive for cytomegalovirus (CMV), and 52% had detectable genital CMV at baseline. Thirty-five individuals acquired STI during follow-up, sometimes with multiple pathogen (17 syphilis, 21 gonorrhea, 14 chlamydia). Syphilis acquisition was associated with genital CMV replication at baseline (19.1% CMV-shedders versus 4.8% non-shedders, p=0.03) and younger age (p=0.02). Lower seminal MCP-1 was associated with higher seminal CMV levels and with syphilis acquisition (p<0.01). For syphilis acquisition, in multivariable Cox-Proportional Hazard model adjusted hazard rates were 3.56 (95%CI:1.00–12.73) for baseline CMV replication and 2.50 (0.92–6.77) for younger age. Conclusions This post hoc analysis suggest that CMV-associated decrease in seminal MCP-1 levels might predispose HIV-infected MSM to syphilis acquisition, but not other STI. Future studies should determine underlying mechanisms and if a causal association exists.
Campylobacter and helicobacter in the etiology of gastrointestinal diseases

The order Campylobacterales comprises two genera: Campylobacter and Helicobacter, with a widespread distribution in both humans and animals. They are Gram-negative, spiral, helical and microaerophilic bacteria, with an optimal growth temperature of 37°C for H. pylori and 42°C for C. jejuni strains. While Helicobacter pylori are restricted to humans, other helicobacter species can be found in different mammals and occasionally in humans. Several Campylobacter species are recognized as human pathogens, while distinct species are pathogenic only occasionally, in children, the elderly and immunocompromised patients. Campylobacters and helicobacters are well adapted to the living conditions inside the gastrointestinal tract, where they can cause diseases as a consequence of inflammation. In addition, they are related to certain extraintestinal diseases, post-infectious sequels, malignancy and autoimmunity. Different clinical presentations of human disorders may be the consequences of the diversity in host immune response, bacterial genome, endotoxin activity as well as specific bacterial virulence factors.
Dyson’s ranks and Maass forms

which were defined by Ramanujan and Watson decades ago. In his last letter to Hardy dated January 1920 (see pages 127-131 of [27]), Ramanujan lists 17 such functions, and he gives 2 more in his “Lost Notebook” [27]. In his paper “The final problem: An account of the mock theta functions” [32], Watson defines 3 further functions. Surprisingly, much remains unknown about these enigmatic series. Ramanujan’s claims about their analytic properties remain open, and there is even debate concerning the rigorous definition of such a function. Despite these seemingly problematic issues, Ramanujan’s mock theta functions indeed possess many striking properties, and they have been the subject of an astonishing number of important works (for example, see [5, 6, 7, 8, 12, 13, 14, 18, 19, 20, 23, 27, 28, 32, 33, 35, 36] to name a few). Watson predicted this high level of activity in his 1936 Presidential Address to the London Mathematical Society with his prophetic words (see page 80 of [32]):

INTEGRATING THE ANALYTIC NETWORK PROCESS AND THE BALANCED SCORECARD FOR STRATEGIC IT OUTSOURCING DECISION MAKING

In outsourcing, management seeks to achieve costs savings, operational efficiency, customer satisfaction, and/or company growth. We integrate the ANP with the perspectives in Balanced Scorecard (BSC) for IT outsourcing decision making. The proposed BSC-ANP model helps evaluate the impact of decision on firm performance and confirms the existence of indicator interactions.
The Myositis Autoantibody Phenotypes of the Juvenile Idiopathic Inflammatory Myopathies

AbstractThe juvenile idiopathic inflammatory myopathies (JIIM) are systemic autoimmune diseases characterized by skeletal muscle weakness, characteristic rashes, and other systemic features. In follow-up to our study defining the major clinical subgroup phenotypes of JIIM, we compared demographics, clinical features, laboratory measures, and outcomes among myositis-specific autoantibody (MSA) subgroups, as well as with published data on adult idiopathic inflammatory myopathy patients enrolled in a separate natural history study. In the present study, of 430 patients enrolled in a nationwide registry study who had serum tested for myositis autoantibodies, 374 had either a single specific MSA (n = 253) or no identified MSA (n = 121) and were the subject of the present report. Following univariate analysis, we used random forest classification and exact logistic regression modeling to compare autoantibody subgroups. Anti-p155/140 autoantibodies were the most frequent subgroup, present in 32% of patients with juvenile dermatomyositis (JDM) or overlap myositis with JDM, followed by anti-MJ autoantibodies, which were seen in 20% of JIIM patients, primarily in JDM. Other MSAs, including anti-synthetase, anti-signal recognition particle (SRP), and anti-Mi-2, were present in only 10% of JIIM patients. Features that characterized the anti-p155/140 autoantibody subgroup included Gottron papules, malar rash, “shawl-sign” rash, photosensitivity, cuticular overgrowth, lowest creatine kinase (CK) levels, and a predominantly chronic illness course. The features that differed for patients with anti-MJ antibodies included muscle cramps, dysphonia, intermediate CK levels, a high frequency of hospitalization, and a monocyclic disease course. Patients with anti-synthetase antibodies had higher frequencies of interstitial lung disease, arthralgia, and “mechanic’s hands,” and had an older age at diagnosis. The anti-SRP group, which had exclusively juvenile polymyositis, was characterized by high frequencies of black race, severe onset, distal weakness, falling episodes, Raynaud phenomenon, cardiac involvement, high CK levels, chronic disease course, frequent hospitalization, and wheelchair use. Characteristic features of the anti-Mi-2 subgroup included Hispanic ethnicity, classic dermatomyositis and malar rashes, high CK levels, and very low mortality. Finally, the most common features of patients without any currently defined MSA or myositis-associated autoantibodies included linear extensor erythema, arthralgia, and a monocyclic disease course. Several demographic and clinical features were shared between juvenile and adult idiopathic inflammatory myopathy subgroups, but with several important differences. We conclude that juvenile myositis is a heterogeneous group of illnesses with distinct autoantibody phenotypes defined by varying clinical and demographic characteristics, laboratory features, and outcomes.
The Economic Theory of Annuities

Annuities are financial products that guarantee the holder a fixed return so long as the holder remains alive, thereby providing insurance against lifetime uncertainty. The terms of these contracts depend on the information available to insurance firms. Unlike age and gender, information about individual survival probabilities cannot be readily ascertained. This asymmetric information causes market inefficiencies, such as adverse selection. Groundbreaking in its scope, The Economic Theory of Annuities offers readers a theoretical analysis of the functioning of private annuity markets. Starting with a general analysis of survival functions, stochastic dominance, and characterization of changes in longevity, Eytan Sheshinski derives the demand for annuities using a model of individuals who jointly choose their lifetime consumption and retirement age. The relation between life insurance and annuities that have a bequest option is examined and "annuity options" are proposed as a response to the lack of secondary markets. This book also investigates the macroeconomic policy implications of annuities and changes in longevity on aggregate savings. Sheshinski utilizes statistical population theory to shed light on the debate of whether the surge in savings and growth in Asia and other countries can be attributed to higher longevity of the population and whether this surge is durable. This book shows how understanding annuities becomes essential as governments that grapple with insolvency of public social security systems place greater emphasis on individual savings accounts
The adoption of family‐friendly HRM policies

Several authors have tried to explain the variation across firms in the implementation of work‐family programmes in terms of the employment strategy of these firms and institutional pressures. But most of these studies have been done in the US context. This study replicates these studies in Spain, which has a very different legal, cultural, and labour market context and where the diffusion of work‐family programmes has only recently started. Using data from a sample of 131 Spanish, mostly private firms, tests five hypotheses that may explain the adoption of family‐friendly human resources management policies. Finds that even in this particular context both the employment strategy and some institutional pressures play an important role. The size of the firm, the percentage of female employees, the presence of a high‐commitment work system and the tightness of the labour market are associated with the implementation of a work/family programme. With the increasing participation of female workers and the ageing of the population expects that work/family programmes will continue to diffuse in Spain.
A Radio Survey of Type Ib and Ic Supernovae: Searching for Engine-driven Supernovae

The association of γ-ray bursts (GRBs) and core-collapse supernovae (SNe) of Type Ib and Ic was motivated by the detection of SN 1998bw in the error box of GRB 980425 and the now secure identification of SN 2003dh in the cosmological GRB 030329. The bright radio emission from SN 1998bw indicated that it possessed some of the unique attributes expected of GRBs, namely, a large reservoir of energy in (mildly) relativistic ejecta and variable energy input. The two popular scenarios for the origin of SN 1998bw are a typical cosmological burst observed off-axis or a member of a new distinct class of supernova explosions. In the former, about 0.5% of local Type Ib/c SNe are expected to be similar to SN 1998bw; for the latter no such constraint exists. Motivated thus, we began a systematic program of radio observations of most reported Type Ib/c SNe accessible to the Very Large Array. Of the 33 SNe observed from late 1999 to the end of 2002, at most one is as bright as SN 1998bw. From this we conclude that the incidence of such events is ≲3%. Furthermore, analysis of the radio emission indicates that none of the observed SNe exhibit clear engine signatures. Finally, a comparison of the SN radio emission to that of GRB afterglows indicates that none of the SNe could have resulted from a typical GRB, independent of the initial jet orientation. Thus, while the nature of SN 1998bw remains an open question, there appears to be a clear dichotomy between the majority of hydrodynamic and engine-driven explosions.
Performance Improvement by Workflow Management Systems: Preliminary Results from an Empirical Study

Workflow Management (WfM) systems have acquired a respectable place in the market of enterprise information systems. Although it is clear that implementation of a WfM system may shorten process execution and increase efficiency, little is known about the extent of these effects on business process performance. In this paper, we report on a running longitudinal multi-case study into the quantitative effects of WfM systems on logistic parameters such as lead time and service time. We conclude that in most cases significant decreases of lead time and service time will take place for the cases under consideration. In the presentation of our research outline, we show how we use process simulation for the validation of our measurements, the prediction of performance improvement, and the comparison of the preand postimplementation situation. As a side effect of this study, we present some interesting characteristics of actual business processes and the way WfM systems are implemented in practice.
