Correlation of Service Quality , Customer Satisfaction , Customer Loyalty and Life Style at Hot Springs Hotels

Taking Lushan Hot Springs Recreational Area as an e xample, this research explores the relationship between hot springs hotels’ service quality, custom er satisfaction, customer loyalty and lifestyle. Re search outcomes indicate that hot springs hotel operators need to enhance customer satisfaction in order to improve customer loyalty directly or enhance servic e quality in order to improve customer loyalty indirectly to enhance profitability and sustain ope rations. Because customers of different lifestyles differ in every dimension, hot springs hotel operators can segment the market via lifestyle variables and undertake different strategies in response to the s ervice quality and customer satisfaction factors va lued by the target market segment in order to attain the goal of enhancing customer loyalty and corporate
Aging-related concerns and body image: possible future implications for eating disorders.

We observed a direct correlation between aging-related concerns about the appearance and Drive for Thinness (Eating Disorders Inventory [EDI]), among males (n = 71) (Pearson r = .36, p < .01) and females (n = 102) (Pearson r = .44, p < .01) from a nonclinical sample of shoppers. Among the women there was a direct correlation between the belief that weight loss is associated with youthful looks and both Drive for Thinness (EDI) (Pearson r = .44, p < .01) and Body Dissatisfaction (EDI) (Pearson r = .27, p < .01). Concerns about the cutaneous stigmata of aging, a commonly recognized sign that a person is older, correlated directly with Drive for Thinness (Pearson r = .27, p < .01) and Body Dissatisfaction (Pearson r = .38, p < .01) among the women. These correlations were all obtained after statistically controlling for the effects of age and body mass index. Our empirical observations may have important future implications in the development of eating disorders, as our society continues to place an inordinate value on youthful looks.
Federal Reserve Bank of New York Staff Reports Illiquidity in the Interbank Payment System following Wide-scale Disruptions Illiquidity in the Interbank Payment System following Wide-scale Disruptions

This paper presents preliminary findings and is being distributed to economists and other interested readers solely to stimulate discussion and elicit comments. The views expressed in the paper are those of the authors and are not necessarily reflective of views at the Federal Reserve Bank of New York or the Federal Reserve System. Any errors or omissions are the responsibility of the authors. Abstract We show how the interbank payment system can become illiquid following wide-scale disruptions. Two forces are at play in such disruptions—operational problems and changes in participants' behavior. We model the interbank payment system as an n-player game and utilize the concept of a potential function to describe the process by which one of multiple equilibria emerges after a wide-scale disruption. If the disruption is large enough, hits a key geographic area, or hits a " too-big-to-fail " participant, then the coordination of payment processing can break down, and central bank intervention might be required to reestablish the socially efficient equilibrium. We also explore how the network topology of the underlying payment flow among banks affects the resiliency of coordination. The paper provides a theoretical framework to analyze the effects of events such as the September 11 attacks. Central Bank for helpful comments.

The cost of doing science on the cloud: The Montage example

Utility grids such as the Amazon EC2 cloud and Amazon S3 offer computational and storage resources that can be used on-demand for a fee by compute and data-intensive applications. The cost of running an application on such a cloud depends on the compute, storage and communication resources it will provision and consume. Different execution plans of the same application may result in significantly different costs. Using the Amazon cloud fee structure and a real-life astronomy application, we study via simulation the cost performance tradeoffs of different execution and resource provisioning plans. We also study these trade-offs in the context of the storage and communication fees of Amazon S3 when used for long-term application data archival. Our results show that by provisioning the right amount of storage and compute resources, cost can be significantly reduced with no significant impact on application performance.
Failure of defective interfering particles of Sindbis virus produced in BHK or chicken cells to affect viral replication in Aedes albopictus cells

Whereas defective interfering particles of Sindbis virus are readily produced in BHK-21 cells or chicken embryo fibroblasts by the techniques of serial undiluted passage, similar methods failed to generate such particles in Aedes albopictus cell cultures. In addition, Sindbis virus stocks produced in BHK-21 cells or chicken embryo fibroblasts and which contained defective interfering particles, when tested in A. albopictus cells, failed (i) to interfere with the replication of standard Sindbis virus and (ii) to change the pattern of intracellular viral RNA synthesis from that produced by infection with standard Sindbis virus alone. We conclude that defective interfering particles of Sindbis virus generated in chicken or hamster cells are silent or inert in mosquito cells.
Sampling frequency of the electrocardiogram for spectral analysis of the heart rate variability

A model is developed to describe and quantitate the error in R-R interval measurement due to the finite sampling frequency. The measured R-R interval is modeled as the sum of the true R-R interval and the error measurement. The first- and second-order statistics of the error are computed in order to investigate its influence on the heart-rate-variability (HRV) power spectrum. The statistics are found to be functions only of the ECG sampling frequency, and it is shown that the power spectrum of the error contributes an additive high-pass-filter-like term (colored noise) to the power spectrum of the HRV. The accuracy of the model is tested by a simulation procedure. The model indicates that the relative balance between the HRV and error power spectra is important and should be checked before any variability analysis of heart rate. <<ETX>>
SELF- EFFICACY, ACHIEVEMENT MOTIVATION AND ACADEMIC PROCRASTINATION AS PREDICTORS OF ACADEMIC ACHIEVEMENT IN PRE-COLLEGE STUDENTS

The purpose of this study was to determine the relationship between academic Selfefficacy, achievement motivation and academic procrastination with academic achievement and investigate predictive validity of them with academic achievement and interaction of them with gender to Academic achievement. To achieve this aim, Samples of 200 (100 male and 100 female) students were selected by multi-stage cluster sampling from high schools of Orumieh. All participants were asked to complete lay’s academic procrastination scale, Hermans achievement motivation scale and self efficacy scale. The data were analysed using, mean, standard deviation, one-way ANOVA, t-test and regression analyses. The result of multiple regression analysis revealed that academic self-efficacy and gender were the best predicators and Academic procrastination inversely is a significant predictor of academic achievement. Also, extra result of t- test revealed that there is no significant between the mean score of girls and boys in academic procrastination (t= 0.47, p=0.64). There was significant difference among boys and girls, in terms of the level of achievement motivation (t=2.06, P=.04), academic achievement (t=.54, p=.000) and academic self-efficacy (t=094, P=0/01).
Global-residual and Local-boundary Refinement Networks for Rectifying Scene Parsing Predictions

Most of the existing scene parsing methods suffer from the serious problems of both inconsistent parsing results and object boundary shift. To tackle these issues, we first propose a Global-residual Refinement Network (GRN) through exploiting global contextual information to predict the parsing residuals and iteratively smoothen the inconsistent parsing labels. Furthermore, we propose a Localboundary Refinement Network (LRN) to learn the position-adaptive propagation coefficients so that local contextual information from neighbors can be optimally captured for refining object boundaries. Finally, we cascade the proposed two refinement networks after a fully residual convolutional neural network within a uniform framework. Extensive experiments on ADE20K and Cityscapes datasets well demonstrate the effectiveness of the two refinement methods for refining scene parsing predictions.
Direction reversal of a rotating wave in Taylor–Couette flow

In Taylor–Couette systems, waves, e.g. spirals and wavy vortex flow, typically rotate in the same direction as the azimuthal mean flow of the basic flow which is mainly determined by the rotation of the inner cylinder. In a combined experimental and numerical study we analysed a rotating wave of a one-vortex state in small-aspect-ratio Taylor–Couette flow which propagates either progradely or retrogradely in the inertial (laboratory) frame, i.e. in the same or opposite direction as the inner cylinder. The direction reversal from prograde to retrograde can occur at a distinct parameter value where the propagation speed vanishes. Owing to small imperfections of the rotational invariance, the curves of vanishing rotation speed can broaden to ribbons caused by coupling between the end plates and the rotating wave. The bifurcation event underlying the direction reversal is of higher codimension and is unfolded experimentally by three control parameters, i.e. the Reynolds number, the aspect ratio, and the rotation rate of the end plates.
Rcl1p, the yeast protein similar to the RNA 3′‐phosphate cyclase, associates with U3 snoRNP and is required for 18S rRNA biogenesis

RNA 3′‐terminal phosphate cyclases are evolutionarily conserved enzymes catalysing conversion of the 3′‐terminal phosphate in RNA to the 2′,3′‐cyclic phosphodiester. Their biological role remains unknown. The yeast Saccharomyces cerevisiae contains a gene encoding a protein with strong sequence similarity to the characterized cyclases from humans and Escherichia coli. The gene, named RCL1 (for RNA terminal phosphate cyclase like), is essential for growth, and its product, Rcl1p, is localized in the nucleolus. Depletion or inactivation of Rcl1p impairs pre‐rRNA processing at sites A0, A1 and A2, and leads to a strong decrease in 18S rRNA and 40S ribosomal subunit levels. Immunoprecipitations indicate that Rcl1p is specifically associated with the U3 snoRNP, although, based on gradient analyses, it is not its structural component. Most of Rcl1p sediments in association with the 70–80S pre‐ribosomal particle and a 10S complex of unknown identity. Proteins similar to Rcl1p are encoded in genomes of all eukaryotes investigated and the mouse orthologue complements yeast strains depleted of Rcl1p. Possible functions of Rcl1p in pre‐rRNA processing and its relationship to the RNA 3′‐phosphate cyclase are discussed.
Three-dimensional Contrast Medium-enhanced Computed Tomographic Cisternography for Preoperative Evaluation of Surgical Anatomy of Intradural Paraclinoid Aneurysms of the Internal Carotid Artery: Technical Note

OBJECTIVE AND IMPORTANCE Precise preoperative evaluation is especially important when internal carotid artery aneurysms in the paraclinoid region are clipped, because these vascular structures are located in close proximity to various important structures such as the optic nerve and anterior clinoid process. We report a new method for “simultaneously” describing the interrelationships among the aneurysm, internal carotid artery, optic nerve, and bony structures with three-dimensional contrast medium-enhanced computed tomographic (3-D CMECT) cisternography. METHODS Informed consent was obtained from the patient. An 8-ml injection of iotrolan (Isovist; Schering, Berlin, Germany) (240 mg I/ml) was administered into the lumbar intrathecal space. A computed tomographic scan of the head was obtained 2 hours later with a multislice Asteion computed tomographic scanner (Toshiba, Inc., Tokyo, Japan). An Alatoview workstation (Silicon Graphics, Mountain View, CA) was used to reconstruct the three-dimensional images. RESULTS These images, as generated by 3-D CMECT cisternography, were found to accurately demonstrate the interrelationships of the internal carotid artery, aneurysm, and surrounding structures preoperatively. The findings obtained from these images proved to be quite similar to the intraoperative findings. 3-D CMECT cisternography clarified whether the paraclinoid aneurysm was intradural or extradural. CONCLUSION 3-D CMECT cisternography was found to provide a useful means for preoperative evaluation of lesions in the paraclinoid area.
Chronic hypoxia reduces adenosine A2A receptor‐mediated inhibition of calcium current in rat PC12 cells via downregulation of protein kinase A

1 Adenosine has been shown to decrease Ca2+ current (ICa) and attenuate the hypoxia‐induced enhancement of intracellular free Ca2+ ([Ca2+]i) in oxygen‐sensitive rat phaeochromocytoma (PC12) cells. These effects are mediated via the adenosine A2A receptor and protein kinase A (PKA). The current study was undertaken to determine the effects of adenosine on Ca2+ current and hypoxia‐induced change in [Ca2+]i during chronic hypoxia. 2 Whole cell patch‐clamp studies revealed that the effect of adenosine on ICa was significantly reduced when PC12 cells were exposed to hypoxia (10 % O2) for 24 and 48 h. 3 Ca2+ imaging studies using fura‐2 revealed that the anoxia‐induced increase in [Ca2+]i was significantly enhanced when PC12 cells were exposed to 10 % O2 for up to 48 h. In contrast, the inhibitory effects of adenosine on anoxia‐induced elevation of [Ca2+]i was significantly blunted in PC12 cells exposed to hypoxia for 48 h. 4 Northern blot analysis revealed that mRNA for the A2A receptor, which is the only adenosine receptor subtype expressed in PC12 cells, was significantly upregulated by hypoxia. Radioligand binding analysis with [3H]CGS21680, a selective A2A receptor ligand, showed that the number of adenosine A2A receptor binding sites was similarly increased during exposure to 10 % O2 for 48 h. 5 PKA enzyme activity was significantly inhibited when PC12 cells were exposed to 10 % O2 for 24 and 48 h. However, we found that hypoxia failed to induce change in adenosine‐ and forskolin‐stimulated adenylate cyclase enzyme activity. Chronic hypoxia also did not alter the immunoreactivity level of the G protein Gsα, an effector of the A2 signalling pathway. 6 Whole cell patch‐clamp analysis showed that the effect of 8‐bromo‐cAMP, an activator of PKA, on ICa was significantly attenuated during 48 h exposure to 10 % O2. 7 We conclude therefore that the reduced effect of adenosine on ICa and [Ca2+]i in PC12 cells exposed to chronic hypoxia is due to hypoxia‐induced downregulation of PKA. This mechanism may serve to reduce the negative feedback on ICa and [Ca2+]i by adenosine and therefore maintain enhanced membrane excitability of PC12 cells during long‐term hypoxia.
Chromium nanoparticles affect antioxidant activity , hormones and sperm parameters in heat-stressed male rats : a model of mammals

The main objective of this study was to assess the effects of nano-chromium (nCr) administration on plasma antioxidant activity, hormones and sperm quality and quantity in male rats exposed to heat stress. Twenty rats were randomly divided into four treatments with five replicates. Treatments were done 35 days included: C, control group received normal saline as gavage and remained at 21 °C; T1, rats exposed to higher temperature than optimum (35 °C) for 6 h/d considered as heat stress (HS); T2, received nano chromium (80 μg/kg body weight) as gavage and remained at 21 °C, and T3, exposed to HS and received nCr. Rats exposed to heat stress had higher antioxidant enzymes activity compared with the control group (P <0.05). In stressed rats, nCr decreased superoxide dismutase, but had no effect on the activity of glutathione peroxidase. Heat stress resulted in decrease (P <0.05) and administration of nCr resulted in increase (P <0.05) in the levels of FSH and testosterone hormones as compared with control group, but had no effect on LH. Administration of nCr in stressed rats (T3) had no effect (P >0.05) on insulin, cortisol and glucose levels as compared with rats in T1 group. Administration of nCr in stressed rats (T3) increased (P >0.05) sperm concentration, viability and normal sperms, as compared with T1 and the control groups, but nCr had no effect on non-stressed rats (T2). It was concluded that nano-particle of chromium administration to stressed rats could ameliorate the negative effects of oxidative stress on antioxidant capacity, activities and sperm quality and quantity.
The sector bound approach to quantized feedback control

This paper studies a number of quantized feedback design problems for linear systems. We consider the case where quantizers are static (memoryless). The common aim of these design problems is to stabilize the given system or to achieve certain performance with the coarsest quantization density. Our main discovery is that the classical sector bound approach is nonconservative for studying these design problems. Consequently, we are able to convert many quantized feedback design problems to well-known robust control problems with sector bound uncertainties. In particular, we derive the coarsest quantization densities for stabilization for multiple-input-multiple-output systems in both state feedback and output feedback cases; and we also derive conditions for quantized feedback control for quadratic cost and H/sub /spl infin// performances.
Temporal stability of pond zooplankton assemblages

1. A large body of recent theory has recently developed focused on the relationship between the species diversity of competitor assemblages and the temporal stability of total competitor biomass. Many of these models predict that stability can increase with increasing diversity. 2. To explore natural relationships between zooplankton taxonomic diversity and temporal stability of total zooplankton biomass, 18 fishless, permanent ponds located in southern Michigan were surveyed over a 5 month period during a single growing season. 3. Results showed that temporal variability in total zooplankton biomass (measured as the coefficient of variation or CV) decreased with increasing mean zooplankton taxonomic richness. Thus, temporal stability increased with increasing taxonomic richness, consistent with theoretical predictions. 4. Decreases in the CV appeared to be because of portfolio effects (statistical averaging of species’ biomass fluctuations) rather than negative covariances among zooplankton taxa. 5. The CV of zooplankton biomass was also related to several environmental variables, suggesting that taxonomic richness may not be the only mediator of biomass stability. The CV decreased with increasing relative abundance of grazer-resistant algae (algae >35 lm in size) and the CV increased with increasing pond productivity.
To Study the Frequency and Outcome of AKI in Children Using Paediatric RIFLE Criteria

DOI: 10.21276/sjams.2018. 6.10. 36 Abstract: To study the frequency and outcome of AKI in children using paediatric rifle criteria. Prospective observational study. All children admitted in PICU over six months' period, from August 2016 to January 2017, in age group of >1 month to 13 years are taken as study group according to the inclusion criteria. All the children of the study group were assigned baseline creatinine clearance value of 100ml/min/1.73m 2 . Creatinine clearance of every child is calculated by using Revised Schwartz formula. For children with deranged creatinine clearance at admission in to PICU or during stay in hospital, pRIFLE class is established. Maximum pRIFLE strata attained by children is documented, outcomes were noted and studied. Primary outcome (mortality) and secondary outcome (morbidity) is measured by Length of stay (LOS) in PICU. A total of 26 children of entire study population are dead (26/200, 13%). 12 children with AKI are died (12/58, 20.68%). Death rate in children with AKI is 2.09 times more than Non AKI group. Deaths among AKI were analyzed, Of the Injury category 4 children died (4/18, 22.22%). 6 children from failure category were dead (6/14, 42.85%). LOS in PICU in children with AKI group is high with a mean LOS of 7.89+/-3.49(95% CI of 0.91< 2-18>) compared to LOS of non AKI patients 4.34+/-1.86(95% CI of 0.30<1-12>). When LOS in hospital is evaluated AKI children had mean of 12.43+/-5.29(95% CI 1.39 <2-30>) compared to non AKI children 8.17+/-3.29(95% CI 0.54<1-30>), which is significant (P<0.05). SCr and UOP seem to be late markers of renal injury, use of classification systems and other serum biomarkers are required to detect AKI earlier to prevent AKI in children prior to a rise in SCr concentration. 2. AKI had increased LOS in PICU, and increased mortality.
Elimination theory for differential difference polynomials

In this paper we give an elimination algorithm for differential difference polynomial systems. We use the framework of a generalization of Ore algebras, where the independent variables are non-commutative. We prove that for certain term orderings, Buchberger's algorithm applied to differential difference systems terminates and produces a Gröbner basis. Therefore, differential-difference algebras provide a new instance of non-commutative graded rings which are effective Gröbner structures.
Effects of single injections of diethylstilbestrol on milk composition and counts of leucocytes in milk of Holstein-Friesian cattle.

Zusammenfassung Untersuchungen uber den Einflus von Diathylstilbesterol-Injektionen auf Milchzusammen-setzung und Gehalt an Leukozyten in Milch von schwarzbunten Kuhen 12 schwarzbunte Kuhe wurden zur Untersuchung von Einflussen von 3 Dosierungs-hohen (10, 30 oder 60 mg) einzelner Injektionen von Diathylstilbestrol (DES) auf Milchmenge, Gehalte an Milchfett, fettfreie Trockensubstanz (SNF), Gesamteiweis, Kasein, Molkeneiweis und Leukozytenzahl benutzt. Statistisch gesicherte Erhohungen in SNF-, Protein-, Kasein- und Molkeneiweisgehalten wurden fur mehrere Tage festgestelk. Die 30-mg-DES/454-kg-Lebendgewicht-Dosierung verursachte starkere Reaktionen denn die 10- oder 60-mg-Dosierung. Kuhe im mehr fortgeschrittenen Laktationsstadium hatten grosere Milchproteingehaltserhohungen. Das Verhaltnis von Kasein zu Gesamteiweis war nicht bedeutend verandert. Mengenzunahmen fur Protein, Kasein und SNF waren statistisch gesichert zwischen dem 5. und 14. Tag nach der Injektion, hatten aber anfanglich erst eine Senkung erfahren. Fettgehalte reagierten in reziprokem Verhaltnis zu Milchmengen. Leukozytenzahlen waren erhoht fur 3 Tage, reagierten am meisten nach der 30-mg-DES-Dosierung und am wenigsten nach der 10-mg-Injektion. Ovariektomierte Kuhe reagierten ahnlich wie die normalen Kuhe nach den Ostrogeninjektionen.
