System Analysis of Mystery Shopping Data: ISO 9001 for Control of Service Quality  [PDF]
E. G. Aminev, Qing Wang
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.29023

The dynamics of service staff in advertences in the filling stations network of one of the largest Russian oil company was investigated. Errors of personnel were revealed from mystery shopping questionnaires and it was proved that the distribution of mistakes can be described by refusing theory. Zipf-Mandelbrot’s model of the statistical structure of languages and, likewise, Gompertz- Makeham’s law of human mortality, are not allowed for approximation. Customer loyalty can be effectively predicted by methods of fast integer linear programming. Relevance factors allow one to authentically judge which components of social behaviour of the personnel have the greatest influence on the benevolence of clients to a company. The personnel are given concrete technologies of training design, statistical methods of detection of incorrect questions and algorithms of estimation of mystery consumer attainment. It is proposed to amend the recommendations of statistical methods to supplement the standard “quality management System” ISO 9001:2008 in the parts concerning with such subjects as personnel, education, training and the modeling of service quality.

Organization Psychoanalysis: Top-Managers Satisfaction Estimation  [PDF]
E. G. Aminev, Wang Qing, Z. Khairullina
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.28004

\"A good chief\" is one of the most important indicators of job satisfaction. However, related to the immediate supervisor, ordinary employees, and especially top-managers do not tend to show it openly. The present study confirms the effectiveness of the solution of this problem with the help of standardized psychoanalytical questionnaires where classic erotic codes are transformed into corporate ones. An integral model for calculating the level of negativity to company policy was received. Approach can be applied effectively in the corporate counseling and within individual reception program of positive psychotherapy.

Analysis of the Low-Energy π±p Elastic-Scattering Data  [PDF]
E. Matsinos, G. Rasche
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.310174
Abstract: We report the results of a phase-shift analysis (PSA) of the low-energy π±p elastic-scattering data. Following the method which we had set forth in our previous PSA [1], we first investigate the self-consistency of the low-energy π±p elastic-scattering databases, via two separate analyses of (first) the π+p and (subsequently) the π-p elastic-scattering data. There are two main differences to our previous PSA: 1) we now perform only one test for the acceptance of each data set (based on its contribution to the overall 2) and 2) we adopt a more stringent acceptance criterion in the statistical tests. We show that it is possible to obtain self-consistent databases after removing a very small amount of the data (4.57% of the initial database). We subsequently fit the ETH model [38] to the truncatedπ±p elastic-scattering databases. The model-parameter values show reasonable stability when subjected to different criteria for the rejection of single data points and entire data sets. Our result for the pseudovector πNN coupling constant is 0.0726±0.0014. We extract the scattering lengths and volumes, as well as the s- and p-wave hadronic phase shifts up to T = 100 MeV. Large differences in the s-wave part of the interaction can be seen when comparing our hadronic phase shifts with the current SAID solution (WI08); there is general agreement in the p waves, save for the ~1/21- hadronic phase shift.

Abstract: Gluten-free bakery products are produced for people suffering from celiac disease due to sensitivity to gluten. So, the aim of this work was to study the effect of partial substitution of rice flour at 20%, 30% and 40% with sorghum and germinated chickpea flours on rheological, physical, sensory properties and staling rate of prepared gluten-free cake. Obtained results showed that germinated chickpea flour had the highest contents of crude protein (23.62%), lipids (4.89%) and crude fibers (5.76%) as compared to other grain flours. Gradual increase in gelatinization temperature and decrease in maximum viscosity and setback were fond of cake batters with increasing the substituting levels of rice flour from 20% to 40% with sorghum or germinated chickpea flours in comparison to rice flour batter. No significant difference was observed in specific volume between rice cake and cake containing 20% of germinated chickpea and sorghum flours which given 2.71, 2.62 and 2.56 cm3/g, respectively. Data also revealed that gluten-free cake lightness (L*) and total intensity significantly increased with 40% of sorghum flour followed by 30 and 20% of sorghum flour. Substitution of 40% rice flour with germinated chickpea flour resulted in significant high in redness (a*), yellowness (b*) and chroma of gluten-free cake being 11.95, 33.72 and 35.77, respectively followed by substituted levels 30% and 20% which attributed to their natural yellow pigments compared with other investigated samples. Overall acceptability of gluten-free cakes was improved after adding 20, 30% of sorghum flour and 20% of germinated chickpea flour which being 90.7, 88.6 and 87.5, respectively compared to rice flour cake (88.4). Rice flour cake was more freshness than wheat flour cake and other treatments during storage duration. After 6 days, rice cake had significant high freshness (306.2%) followed by gluten-free cake samples with 20% of sorghum or germinated chickpea flours which given 294.5% and 289.4%, respectively. Generally, it could be concluded that the quality and nutritional properties of gluten-free

Abstract: Financial crisis is an unfortunate reality that overshadows any financial system regardless its profitability and the level it functions. The appearance of crises across financial markets, especially during the 1990s that the internationalized markets adopted a rather approachable character, imposed severe costs in financial and social systems. With this paper is proposed the generation of a future interval of time that is vulnerable to enclose the burst of a financial crisis. A time series consisted of approximations of the local Lipschitz constant is examined and in the proposed forecasting approach this constant holds the crisis indicator role. Further the application of two different optimization techniques over the Lipschitz-made time series results to the generation of a future period of time; this interval is likely to envelop the burst of a forthcoming crisis. The usage of a future interval of time empowers the predicting ability of the methodology by providing warning signs priory to the actual crisis burst. To this direction, the obtained results offer strong evidence that the method may be characterized as an Early Warning System (EWS) for financial crisis prediction.

Modern Research in Catalysis (MRC) , 2014, DOI: 10.4236/mrc.2014.34015
Abstract: The use of heterogeneous catalysts in the transesterification reaction of vegetable oils has getting emphasis in recent years, mainly by the alternative of obtaining clean fuel derived from renewable sources. Metal oxide such as MgO or CaO, supported ones like \"\" and zeolites are often applied in transesterification process. Among them, hydrotalcite has shown potential as catalysts on this reaction due to their physicochemical properties, such as: thermal stability, porosity, specific surface area, memory effect, basicity, acidity and anion exchange capacity. This work studies the catalytic performance of the calcium and aluminum based hydrotalcite in the transesterification reaction of soybean oil in methanol and ethanol. The hydrotalcite samples treated at 450?C were impregnated with KOH. The efficiency of impregnated and non- impregnated samples was compared and the non-impregnated one showed the best performance. This property was attributed to the higher availability of active sites used in the transesterification process.

Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.48A002
Abstract: We propose an accurate non numerical solution of the Fisher Equation (FE), capable of reproducing the known analytical solutions and those obtained from a numerical analysis. The form we propose is based on educated guesses concerning the possibility of merging diffusive and logistic behavior into a single formula.

We study local linear non-axisymmetric perturbations in fully stratified 3D astrophysical disks. Radial stratification is set to be described by power law, while vertical stratification is set to be exponential. We analyze the linear perturbations in local shearing sheet frame and derive WKB dispersion equation. We show that stratification laws of the disk matter define not only the thermal stability of the disk, but also the efficiency of the potential vorticity production by rotationg convective turbulence in astrophysical disks. Taken developed convective turbulence we assume nonlinear tendencies set by linear spectrum and show that vortices are unlikely to be generated in rigid rotation flows. In contrast, differential rotation yields much higher vortex production rate that depends on the disk thickness, distance from the central object and the spectral characteristics of the developed thermal turbulence. It seems that measurements of the temperature and density distribution in accretion disks may indicate the efficiency of the turbulence development and largely define the luminosity characteristic of accreting flows.

In the well-known superfamily of transforming growth factors beta (TGF-b), bone morphogenetic proteins (BMPs) are one of the most compelling cytokines for their major role in regulation of cell growth and differentiation in both embryonic and adult tissues. This subfamily was first described for its ability of potentiating bone formation, but nowadays, the power of BMPs is well beyond the bone healing scope. Some of the BMPs have been well studied and described in the literature, but the BMP9 is still worthy of attention. It has been shown by many authors that it is the most potent osteogenic BMP. Moreover, it has been described as one of the rare circulating BMPs. In this paper, we will review the recent literature on BMP9 and the different avenues for future research in that field. Our primary scope is to review its relation to bone formation and to elaborate on the available literature on other systems.

Microstructure and Corrosion Properties of the Plasma-MIG Welded AA5754 Automotive Alloy  [PDF]

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2015, DOI: 10.4236/jmmce.2015.34034
Abstract: The influence of heating cycles during plasma metal inert gas (MIG) welding on the microstructure and corrosion properties of the AA5754 automotive alloy has been investigated. The high heat input during plasma-MIG welding results in a significant modification in the microstructure of the AA5754 alloy adjacent to the fusion boundaries. As a consequence of partial melting of the Al-Fe-Mn-(Si) intermetallics at the partially melted zone (PMZ) and segregation of the high melting point elements (particularly Fe and Mn) toward the fusion zone, severe galvanic corrosion attacks can be enhanced along the PMZ of the AA5754 weld during exposure to aqueous corrosion environments.
