Performance Evaluation of Supply Chain under Decentralized Organization Mechanism

Abstract Nowadays among many evaluation methods, data envelopment analysis has widely used to evaluate the relative performance of a set of Decision Making Units (DMUs). Data Envelopment Analysis (DEA(is a mathematical tool for evaluating the relative efficiency of a set Decision Making Units (DMUs), with multiple inputs and outputs. Traditional DEA models treat with each DMU as a “black box" thus, the performance measurement may be not effective. So, there are necessities for network DEA models. The objective of this paper is to propose a new network DEA model for measuring the efficiency of two- supplier and one manufacturer chains under the decentralized organization mechanism. In this mechanism, each section of supply chain is controlled under unique decision maker with his/her own interest. We proposed that, in comparison with CCR model, for the supply chain under decentralized organization mechanism, it is not appropriate to ignore the internal structure and treat as a “black box”, while there is more than one decision maker with different interests. Furthermore, the relation between the supply chain efficiency and division efficiency is investigated. Numerical example demonstrates the application of the proposed model.
Development of motion compensated 3D T2 mapping for cardiac imaging

Purpose: T2 mapping can detect variations in the water content of the myocardium. As it consists of a quantitative approach, this technique overcame some of the limitations present in the commonly used T2-weighted MRI. In fact, this type of methodology is becoming increasingly important for tissue characterization in patients with myocardial pathologies (e.g. myocardial edema). As a large set of images may be needed to calculate each parameter, scans have been typically limited to 2D images acquired during breath-holding (BH). The aim of this project was to extend the commonly used breath hold approaches enabling free breathing while attaining high resolution whole heart images by developing and test a free-breathing, whole heart T2 mapping technique at 3.0T. Methods: To generate T2 maps, multiple images are acquired with varying degrees of T2 weighting using magnetization preparation. In this work, imagebased navigation (iNAV) was combined with a dynamic T2 prepared sequence with a varying T2prep echo time to investigate the feasibility of iNAV for T2 mapping with 100% scan efficiency. ECG-triggering, interleaved acquisitions and a saturation pulse – to reset the magnetization on every heartbeat – were used in the module. A monoexponential function is adjusted to the images intensities and with the fitting the T2 maps are generated. The work consisted in adapting the MRI pulse sequence for T2 mapping by introducing iNAV for respiratory motion correction and evaluation of the new 3D T2mapping scan in phantoms as well as healthy subjects. Results: In healthy volunteers the T2 values did not display significant differences (p < 0.05) when the results obtained with the proposed approach (45.7 ± 5.7 ms), were compared to those obtained with previous methods the 3D T2prep corrected with the pencil beam navigator (47.1 ± 8.9 ms) and the breath-held 2D T2prep (46.1 ± 6.3 ms). Conclusion: The proposed free-breathing whole heart 3D T2 mapping approach is feasible and can be performed within less than 5 min with similar accuracy to that of the 2D-BH T2 mapping approach. Also, it may be applicable in myocardial assessment instead of current clinical black blood sequences.

Information technologies Variable Length Niche Algorithm and Application in Fuzzy Image Edge Detection

The image edge detection is the point that the obvious change of the brightness in the digital image is marked, and the information not related is removed, and the important attribute of the image is preserved. The traditional edge detection algorithm uses the Gauss filter algorithm, and the edge detection of the fuzzy image is not good. A fuzzy edge detection algorithm based on the variable length niche algorithm is proposed in this paper. Fuzzy image edge detection of the tentor space model is established. In tensor space with 4 layer Morlet wavelet decomposition method for processing of image feature extraction and the noise reduction filter, to extract the image pixel feature of variable length coding, to simulate the properties of biological evolution, the punishment which adapt to small valves of individuals, by variable length coding and niche algorithm of redundant information out, effectively ability is insufficient problem. Simulation results show that the proposed method has the highest PSNR value, and the edge of the image is the best, which has better connectivity and color difference.
Mental health workers' views about their suicide prevention role

Aim: Mental Health workers bear responsibility for preventing suicide in their client group. Survey studies have indicated that staff can be seriously adversely affected when a client suicides. The aim of the current study is to describe and evaluate the effects on mental health (MH) workers of their ongoing role in managing suicidal behaviours and to identify the thoughts and feelings associated with this role. Method: A survey was administered to 135 MH workers via an on-line self-report vehicle. The survey comprised standardised measures of anxiety and burnout as well as a questionnaire developed for this study concerning perceptions and attitudes to suicide and suicide prevention. Results: Factor analysis of 12 retained items of the questionnaire identified three factors: 1) preventability beliefs (beliefs about suicide being always and/or permanently preventable); 2) associated distress (stress/anxiety about managing suicidal behaviour); and 3) the prevention role (covering views about personal roles and responsibilities in preventing suicidal behaviours). Analysis of these factors found that many MH workers experience an elevation of stress/anxiety in relation to their role in managing suicidal behaviours. This distress was associated with the emotional exhaustion component of burnout. Measures showed adverse responses were higher for outpatient than inpatient workers; for those who had received generic training in suicide prevention: and for those who had experienced a workplace related client suicide. Conclusion: There is a need for the development of appropriate self-care strategies to alleviate stress in MH workers exposed to suicide.
Forest of Bliss: Sensory Experience and Ethnographic Film

Forest of Bliss (1986) is a film that explores the ancient Indian city of Benares, focusing on both funeral and religious practices. The viewer comes to know the city through the eyes of ethnographic filmmaker Robert Gardner. He describes it by the use of complex editing that allows this documentary to be included in the subgenre of city symphony. The film is distinguished both by its dense network of visual and aural symbols with which the cycle of death and regeneration is represented and by its ability to communicate the sensory experience of being there.

Iterative Dipole Moment Method for the Dielectrophoretic Particle-Particle Interaction in a DC Electric Field

Electric force is the most popular technique for bioparticle transportation and manipulation in microfluidic systems. In this paper, the iterative dipole moment (IDM) method was used to calculate the dielectrophoretic (DEP) forces of particle-particle interactions in a two-dimensional DC electric field, and the Lagrangian method was used to solve the transportation of particles. It was found that the DEP properties and whether the connection line between initial positions of particles perpendicular or parallel to the electric field greatly affect the chain patterns. In addition, the dependence of the DEP particle interaction upon the particle diameters, initial particle positions, and the DEP properties have been studied in detail. The conclusions are advantageous in elelctrokinetic microfluidic systems where it may be desirable to control, manipulate, and assemble bioparticles.
Forecasting Latin America’s Country Risk Scores by Means of a Dynamic Diffusion Model

Over the last years, worldwide financial market instability has shaken confidence in global economies. Global financial crisis and changes in sovereign debts ratings have affected the Latin American financial markets and their economies. However, Latin American’s relative resilience to the more acute rise in risk seen in other regions like Europe during last years is offering investors new options for improving risk-return trade-offs. Therefore, forecasting the future of economic situation involves high levels of uncertainty. The Country Risk Score (CRS) represents a broadly used indicator to measure the current situation of a country regarding measures of economic, political, and financial risk in order to determine country risk ratings. In this contribution, we present a diffusion model to study the dynamics of the CRS in 18 Latin American countries which considers both the endogenous effect of each country policies and the contagion effect among them. The model predicts quite well the evolution of the CRS in the short term despite the economic and political instability. Furthermore, the model reproduces and forecasts a slight increasing trend, on average, in the CRS dynamics for almost all Latin American countries over the next months.
Earthworms: Charles Darwin’s ‘Unheralded Soldiers of Mankind’: Protective & Productive for Man & Environment

Earthworms promises to provide cheaper solutions to several social, economic and environmental problems plaguing the human society. Earthworms can safely manage all municipal and industrial organic wastes including sewage sludge and divert them from ending up in the landfills. Their body work as a ‘biofilter’ and they can ‘purify’ and also ‘disinfect’ and ‘detoxify’ municipal and several industrial wastewater. They reduce the BOD & COD loads and the TDSS of wastewater significantly. They can even remove the EDCs (endocrine disrupting chemicals) from sewage which is not removed by the conventional sewage treatments plants. Earthworms can bio-accumulate and bio-transform many chemical contaminants including heavy metals and organic pollutants in soil and clean-up the contaminated lands for re-development. Earthworms restore & improve soil fertility by their secretions (growth hormones) and excreta (vermicast with beneficial soil microbes) & boost ‘crop productivity’. They have potential to replace the environmentally destructive chemical fertilizers from farm production. The ‘protein rich’ earthworm biomass is being used for production of ‘nutritive feed materials’ for fishery, dairy & poultry industries. They are also being used as ‘raw materials’ for rubber, lubricant and detergent industries. The bioactive compounds isolated from earthworms are finding new uses in production of ‘life saving medicines’ for cardiovascular diseases and cancer cure.
Quantitative Comparisons of Six-Phase Outer-Rotor Permanent-Magnet Brushless Machines for Electric Vehicles

Multiphase machines have some distinct merits, including the high power density, high torque density, high efficiency and low torque ripple, etc. which can be beneficial for many industrial applications. This paper presents four different types of six-phase outer-rotor permanent-magnet (PM) brushless machines for electric vehicles (EVs), which include the inserted PM (IPM) type, surface PM (SPM) type, PM flux-switching (PMFS) type, and PM vernier (PMV) type. First, the design criteria and operation principle are compared and discussed. Then, their key characteristics are addressed and analyzed by using the finite element method (FEM). The results show that the PMV type is quite suitable for the direct-drive application for EVs with its high torque density and efficiency. Also, the IPM type is suitable for the indirect-drive application for EVs with its high power density and efficiency.
Comparison Between Clinical Features and Residual Depressive Symptoms of Patients with Bipolar Depressive and Unipolar Depressive Disorder in Remission

Introduction: Even though particularly bipolar depression and unipolar depression, which are among mood disorders, seem to be similar, they show differences in terms of the course and treatment process. It is important to determine the distinctive features and predictors of these two disorders. The purpose of this study was to examine the differences between the sociodemographic and clinical features and residual depressive symptoms in the unipolar depressive and bipolar depressive disorder groups. Method: The study consisted of patients who applied to the Psychiatry Polyclinic of Ankara Numune Training and Research Hospital between 01.10. 2010-01.05. 2011 and were diagnosed with Bipolar Affective Disorder and Recurrent Major Depression according to SCID-I. As a result of the interviews, 96 patients with Bipolar Affective Disorder and 58 patients with Recurrent Major Depression, who were stable according to CGI, received a score of 7 and below from the hamilton rating scale for depression and a score of 5 or below from the young mania rating scale, were included in the study. Then sociodemographic information form, hamilton rating scale for depression, young mania rating scale, CGI and TEMPS-A Temperament scale were performed on patients which were deemed appropriate by applying the Structured Clinical Interview (SCID-I) for DSM-IV-TR Axis I Disorders. Results: The comorbidity rate of psychotic features was high in a statistically significant way in the BAD group (<0,001). The episodes of patients in the BAD group were higher in a statistically significant way, in terms of seasonal cycle compared to the MD group (<0,001). Considering the Hamilton depression subscales individually; the scores of psychic anxiety, general somatic symptoms and suicide (consideration of life not worth living) were higher in the MD group, compared to the BAD group. In the BAD group, on the other hand, scores of the genital symptoms and retardation were higher in a statistically significant way, compared to the MD group. Scores of depressive mood, guilt thoughts, suicide (consideration of life not worth living), loss of interest in work and activities as before and somatic anxiety were higher in individuals with anxious temperament. Conclusion: As a consequence, this study determined different residual symptoms in the bipolar affective disorder and major depression groups in remission, which shows a parallelism with the previous data. While psychic anxiety, general somatic symptoms and suicidal ideation were generally observed in unipolar depression, sexual side effects and retardation were in the forefront in the BAD group. Regarding patients who applied to the hospital with the first episode of depression, symptoms observed during the episode, case history, and residual depressive symptoms might give information to us about distinguishing the unipolar depression and bipolar disorder depressive episode.
The mechanism of the surface morphology transformation for the carbon nanotube thin film irradiated via excimer laser

In this paper, the surface morphology transformation of the sprayed carbon nanotube (CNT) thin film irradiated with the excimer laser has been systematically investigated. Under the excimer-laser irradiation, two phenomena, including the annealing and ablation effects, were found to be dependent on the incident laser energy and overlapping ratios. Moreover, the extremely high protrusions would be produced in the interface between the annealing and ablation regions. The mechanism of the CNT thin film under the excimer laser irradiation was, therefore, proposed to derive the surface morphology modifications and the further reinforced crystallinity with proper laser energy densities and overlapping ratios.
Using fuzzy Choquet Integral operator for supplier selection with environmental considerations

The increasing importance of considering environmental issues as a part of the corporate social responsibility, which has environmental and social impacts as well as affects the image and competitiveness of a firm, has encouraged companies to revise their major processes of supply chain management (SCM). Since the performance of a company heavily relies on its suppliers, it is of vital importance to incorporate environmental criteria into supplier selection problem to satisfy both conventional and environmental criteria, which have only been considered by a limited number of studies. Therefore, following a brief review of green supply chain management (GSCM) and sustainable supply chain management (SSCM) concepts and investigation of supplier selection approaches, this study after focuses on a modified Delphi method that has been applied to determine supplier selection criteria. Also, the intuitionistic fuzzy value (IFV) and interval value intuitionistic fuzzy (IVIF) have been utilised for supplier evaluation regarding the subjective nature and uncertainty of judgment. By using the Choquet Integral operator and fuzzy measures, the best supplier has been selected, and the comparison between IFV and IVIF has been made. This methodology has been applied to a manufacturing company to assess the applicability of the proposed methodology. The proposed methodology can be used for real world problems that contain fuzziness or interacting decision criteria. Moreover, due to a high level of expert involvement in the decision-making process, we claimed that the knowledge of experts has been utilised constructively.
Silver nanoparticles induced genotoxicity and oxidative stress in tomato plants

Among nanoparticles, silver nanoparticles (AgNPs) are intensively used in many materials owing to their antibacterial effects. In the present study different concentrations of AgNPs in Hoagland solution were applied to tomato seedlings. Total chlorophyll content, relative water content (RWC), antioxidant enzyme activities, and malondialdehyde content (MDA) as well as the genomic template stability (GTS) were analyzed. The intersimple sequence repeat polymerase chain reaction assay (ISSR-PCR) was used to determine the genotoxic effects of AgNPs on DNA. RWC did not change under AgNPs treatments; however, total chlorophyll content was significantly reduced by AgNPs applications. ISSR profiles demonstrated a consistent increase in polymorphic bands by the increase in the concentration of AgNPs. GTS value was also reduced depending on the concentration of AgNPs. SOD and APX activities were increased under low AgNPs treatments; however, these activities were decreased under high concentrations of AgNPs treatments. Tomato plants could be sensitive to AgNPs within the increase in MDA content in all of the AgNPs treatments. AgNPs nanotoxicity could be quite dose-dependent. AgNPs could also have negative effects on tomato plants by enhancing DNA damage and lipid peroxidation.
Destination Image on the DMO's Platforms: Official Website and Social Media

Tourists usually configure and develop ideas about possible destinations based on information previously gathered from both social media and the official web of the destination management organization (DMO). In spite of the relevance of said information sources, there have not been many studies evaluating how these different sources influence the destination image. This research proposes a model intended to explain the image creation process of a destination taking into account both the DMO’s online platforms and the perceived psychological distance. The proposed model is tested with an empirical study including a questionnaire which collects data from 264 participants. The validity of the model is reviewed through PLS analysis. Results show that the psychological distance does not influence the overall destination image. In addition, the overall destination image can be estimated to a larger extent when tourists approach social media as their main source of information. Implications and conclusions are discussed.
Foliar Application of Salicylic Acid, Methyl Jasmonate and Potassium Sulfate on Photosynthetic Characteristics and Fruit Quality of Pomegranate

The present research designed to evaluate the effects of foliar application of methyl jasmonate (MeJA), salicylic acid (SA) and potassium sulfate on improving fruit quality and photosynthesis system. Ten treatments include: SA (0.3, 0.6 and 0.9 mM), MeJA (0.5, 1 and 2 mM), potassium sulfate (0.5, 1 and 1.5%) and distilled water (control) were sprayed on pomegranate trees 2 and 7 weeks after full bloom early in the morning. Results indicated that SA, MeJA and potassium sulfate increased phenolic compound and 1.5% of potassium sulfate and 0.5 mM of MeJA significantly increased the antioxidant activity of pomegranate fruit. Application of SA at 0.6 mM increased significantly hue angle of fruit peel. Foliar application of potassium significantly increased Fv/Fm and Pi parameter. Furthermore, total chlorophyll, b chlorophyll and cartenoids increased by 0.5 % of potassium sulfate, however, the differences were not significant. Besides, 1% and 1.5% of potassium sulfate significantly increased the pH of fruit juice.
