Overreliance on mobile payment solutions for purchasing air tickets in China

A mobile payment solution allows users to pay for a wide range of products and services by accessing their virtual wallets via their Internet-connected mobile phones. The use of such an innovative payment process has been on the rise in Mainland China, in which Alibaba and Tencent are considered the market leaders. As this payment solution has become the major payment mode preferred by residents of China, businesses may suffer from the risk of overreliance if the service becomes unavailable depending on the regulations imposed by the Chinese government. In this study, five operation department heads of a large-scale online travel agency in Shenzhen were conducted. This study aims to understand the current situation, including the level of reliance, presence of alternative payment solutions, negative impact of the possible absence of these solutions, and contingency plans in risk management
Relationship of Attachment Styles with Addiction Susceptibility in Children

Background: Attachment styles play an important role in children healthy and risky behaviors. The present study plans to investigate, whether different attachment styles leads to shaping various addiction susceptibility in children? Objective: Participants were 358 high schools adolescent with the age range of 14-19 and were chosen using cluster random sampling. Data were gathered using addiction susceptibility questionnaire- adolescent version and attachment styles questionnaire. Data were analyzed using multiple regression and partial correlation. Results: The results showed children’s preoccupied, fearful and dismissing insecure attachment styles have a positive relationship with addiction susceptibility. Children’s insecure attachment styles are direct predictors of addiction susceptibility. Children’s secure attachment style has a negative relationship with addiction susceptibility. Children’s secure attachment style is a reverse predictor of addiction susceptibility. Conclusion: Thus, secure attachment is a valid index for psychological health. Insecure attachment styles are good predictor for addiction susceptibility and they can be used as a scale for identifying of at risk individuals for drug abuse in prevention plans.
Sojourn times in a multiclass processor sharing queue

We consider a processor sharing queue with several customer classes. For an arbitrary customer of class i we show that the sojourn time distribution is regularly varying of index -\nu_i iff the service time distribution is regularly varying of index -\nu_i, and derive an explicit asymptotic formula. Furthermore, the tail of the sojourn time distribution of customer class i is shown to be unaffected by the tails of the service time distributions of other customer classes, even if some of the latter tails are heavier. This result implies that, when the sojourn time of a customer is large, this is not due to long service requirements of other customer types. In particular, short-range dependent traffic does not suffer from longe-range dependent traffic if processor sharing is used as a service discipline.

Use of genetic variance to determine weighting factors for genomic information used in single step genomic evaluation

Single step genomic BLUP (SS-GBLUP) has recently been implemented in the Australian beef cattle and sheep industries. Selection of the weighting factor () to combine the genomic and pedigree relationship matrixes could affect the accuracies of EBV. Cross validation has been used as a method to determine the optimal . This study estimated genetic variances using models fitting the genomic relationship matrix (G, Vg), the pedigree relationship matrix (A, Va), or both (Vt), and used the ratio Vg/Vt as an alternative approach to identify the optimal . Results showed that the ratio of genetic variances (Vg/Vt) aligned reasonably well with the optimal values of for most traits. Compared with cross validation, this approach was computationally fast, and can be used as an alternative to identify the optimal values of in SS-GBLUP.
Mössbauer , FTIR and FE SEM investigation of iron oxides precipitated from FeSO 4 solutions

Mössbauer and Fourier transform infrared (FT-IR) spectroscopies and thermal field emission scanning electron microscopy (FE SEM) were used to investigate the precipitation of iron oxides from FeSO4 solutions. The hydrolysis of urea at 90 C was utilized as a generator of OH ions needed for the precipitation of iron oxides. The formation of specific iron oxyhydroxide or oxide phase depended on the concentration of FeSO4 and urea, as well as on the rate of oxygenation. In dependence on the experimental conditions different iron oxide phases, such as goethite, hematite and magnetite were found in the precipitates. Mössbauer spectra showed only the formation of substoichiometric magnetite (Fe3-xO4). Significant spectral differences in the RT Mössbauer spectrum of goethite phase were observed, and the spectra showing the presence of this phase could be fitted only taking into account the distribution of hyperfine magnetic fields. FE SEM inspection showed varying sizes and geometrical shapes of goethite particles. Goethite particles were elongated along the crystallographic c-axis. 2006 Elsevier B.V. All rights reserved.
Epitaxial Growth of Germanium on Silicon for Light Emitters

This paper describes the role of Ge as an enabler for light emitters on a Si platform. In spite of the large lattice mismatch of ~4.2% between Ge and Si, high-quality Ge layers can be epitaxially grown on Si by ultrahigh-vacuum chemical vapor deposition. Applications of the Ge layers to near-infrared light emitters with various structures are reviewed, including the tensile-strained Ge epilayer, the Ge epilayer with a delta-doping SiGe layer, and the Ge/SiGe multiple quantum wells on Si. The fundamentals of photoluminescence physics in the different Ge structures are discussed briefly.
Time Course of Changes in Passive Avoidance and Y-Maze Performance in Male Diabetic Rats

Diabetes mellitus is accompanied with disturbances in learning, memory, and cognitive skills in the human society and experimental animals. Therefore, this research study was conducted to evaluate time-dependent changes in passive avoidance and Y-maze performance in male diabetic rats. For this purpose, male Wistar rats were randomly divided into control and diabetic groups. For induction of diabetes, streptozotocin (STZ) was injected i.p. at a single dose of 60 mg/kg. For evaluation of learning and memory, initial latency (IL) and step-through latency (STL) were determined at the end of 1 st , 2 nd , and 3 rd months using passive avoidance and Y-maze tasks. It was found out that mean IL exhibits a significant increase only at the end of 2 nd (p<0.05) and 3 rd (p<0.01) months. In addition, STL significantly reduced at the end of 2 nd (p<0.05) and 3 rd months (p<0.01). Regarding Y-maze task, alternation score of the diabetic rats was lower than that of the control ones at the end of 1 st (p<0.05), 2 nd (p<0.01), and 3 rd (p<0.01) months as compared to time-matched control group. To conclude, at least one month is strictly required for development of behavioral disturbances in passive avoidance and Y-maze tasks in STZ-diabetic rats. Iran. Biomed. J. 10 (2): 99-104, 2006
Optimization of energy window for different body mass index in biograph truepoint positron emission tomography imaging system

Internal scattering in patient’s body is one of the key factors that leads to PET image quality degradation. This interaction affects the imaging performance in the sense of mispositioning of the annihilation position and coincidence data lost. One of the factors that determines the probability of this interaction is the patient’s body weight. In practice, the impact of scattering is worse with the increment of the patient’s body weight. Thus, optimization of scatter events contribution in the raw data prior to image reconstruction is vital as it determines the quality of PET image generated. The quality of the image, which eventually help to determine the tumor detection rate, will improve the survival rate of the cancer patient. Various methods were proposed and identified by the previous studies to minimize the contribution of both patient and detector’s scatter to the raw data. This study, was nonetheless achieved the above target through the analysis of signal processing. The aim of this study is to define the optimal energy threshold level for the different groups of patient’s body. The definition was done based on the phantom’s modeling. Various patient’s sizes in the range of 44.0 kg to 99.0 kg which yield diameters of 20 cm to 30 cm were modeled using Monte Carlo N-Particle code version 5 (MCNP5). The impact of phantom’s masses to the several measurement parameters like scatter fraction, tumor visibility and signal to noise ratio (SNR) also was tested in order to define the optimal energy threshold level for each phantom size. Various energy threshold levels were implemented on the simulated data. Evaluation of tumor SNR on the reconstructed image was the core measure used in this study. The optimal energy threshold value was defined when the maximum SNR was yielded at the respective energy window used. At the end of this study, we managed to propose an optimal energy window for the underweight, normal and obese patient. The obese phantom which lost more photons via photon scattering and attenuation thus required up to 20.00% and 27.27% larger energy window than the underweight and normal phantom respectively. These threshold values, which are 2.30% to 13.79% varies from the default energy window that commonly practiced, improves the SNR up to 1.24%. At the end of this study, we managed to propose an equation that gave correlations among the body weight, the tumor to background ratio (TBR) and the optimal energy threshold level. The derivation of this equation was done based on the data obtained in this study. The proposed equation, therefore allows definition of the optimal energy window for any condition of imaging, particularly those related to the weight of the patient’s body and TBR or standard uptake values (SUV) of the tumor.
FOSTERING CREATIVITY IN EARLY CHILD’S EDUCATION

The whole idea of this paper spins mainly about one of the main aspects within early child’s education – creativity and its meaning to a child’s psychosocial development. The presented findings rely on the methodological approach supported by Reggio Emilia philosophy. Creativity education, especially based on Reggio Emilia point of view, starts from the very young age and therefore kindergartens as well as families play much significant role to support and develop creativity roots in child’s everyday routine. It is stressed that being creative is more like being initiative and innovative – the features that are mainly required by contemporary society. Also this paper is illustrated with real-life pictures from the activities in the kindergarten “Lazdynėlis”, so it becomes much clearer for those who are interested in this topic to understand how kindergarten daily life may sustain, develop and so enhance creativity of children using many different approaches, e.g. through the game-led tools, teachers’ attitudes etc. KEY WORDS: children, creativity, early child’s education, and Reggio Emilia educational philosophy.

Abelian Duality for Generalised Maxwell Theories

We describe a construction of generalised Maxwell theories -- higher analogues of abelian gauge theories -- in the factorisation algebra formalism of Costello and Gwilliam, allowing for analysis of the structure of local observables. We describe the phenomenon of abelian duality for local observables in these theories as a Fourier dual, relating observables in theories with dual abelian gauge groups and inverted coupling constants in a way compatible with the local structure. We give a description of expectation values in this theory and prove that duality preserves expectation values. Duality is shown to, for instance, interchange higher analogues of Wilson and 't Hooft operators.
A PROSPECTIVE STUDY OF ADDITION OF SITAGLIPTIN TO METFORMIN VERSUS METFORMIN ALONE IN TYPE 2 DIABETES MELLITUS PATIENTS

BACKGROUND Various oral hypoglycaemic agent has been used for the treatment of diabetes mellitus. Out of that, metformin is a biguanide, which is commonly used for the treatment of diabetes mellitus and sitagliptin is an orally effective inhibitor of dipeptidyl peptidase IV, which indirectly increase the secretion of insulin by preventing degradation of GLP-1. Present study is designed to evaluate the efficacy of addition of sitagliptin with metformin in comparison with metformin alone.
Hatchability of chicken eggs as influenced by turning frequency in hurricane lantern incubator

An experiment was conducted to determine the influence of turning frequency of chicken eggs on hatchability in hurricane lantern incubator. There were four treatments in which eggs were not turned in treatment one (control), those in treatment two were turned once daily (morning), treatment three turned twice daily (morning and afternoon) while treatment four were turned thrice daily (morning, afternoon and evening). A range of 9.86 - 11.51% egg weight loss was obtained with the lowest value of 9.86% recorded in the control experiment. Egg turning three times daily produced highest hatchability of 72.90%. Embryonic mortality occurred in all the treatments. Early embryonic mortality (DIG) was highest (70.85%) in treatment two while late embryonic mortality (DIS) was highest (66.65%) in treatment three. Hatching occurred in the three zones of the egg. Most of the chicks hatched from the equatorial region while few ones hatched from the narrow end of the egg. Manual turning of eggs three times a day is recommended for hurricane lantern incubator in order to enhance minimal egg weight loss and higher hatchability of chicks. Such incubator could be used for hatching eggs of domestic fowls, turkeys, ducks, etc thereby taking hatchery operations to the door- steps of small-scale poultry farmers.
Does Autologous Conditioned IL-1 Antagonist (ACS) Reduce Pain in Patients with OA or Lumbar Radiculopathy?

Objective: To determine whether or not Autologous conditioned IL-1 antagonist (ACS) reduce pain in patients with OA or lumbar radiculopathy. Study Design: Review of 3 randomized, double-blind controlled clinical trials in 2007, 2008, and 2009, all in English. Data Sources: Two randomized, double-blinded controlled clinical trials comparing the effectiveness of intraarticular injections of an autologous IL-1 receptor antagonist solution versus a control in OA and one randomized, double-blinded controlled clinical trials comparing autologous IL-1 receptor antagonist epidural injection versus 5 and 10 mg triamcinolone in patients with lumbar radiculopathy. Outcomes Measured: The outcomes in this study were measured using the Western Ontario and McMaster Osteoarthritis Index (WOMAC), Knee Injury and Osteoarthritis Outcome Score (KOOS), Visual Analogue Scale (VAS), and the Oswestry Disability Index (ODI). Results: Baltzer et al. determined a statistically significant reduction in OA-related pain when compared to both saline and hyaluronic acid. Yang et al. failed to show pain reduction in ACStreated patients when compared to placebo. Becker et al. reported significant reductions in pain, but were not statistically significant when compared to the control arm. Conclusion: Results of the mentioned studies proved that ACS does decrease pain in patients with OA and LR; however, this pain reduction was not universally statistically significant and thus requiring further, more uniform trials. The Baltzer et al. results were encouraging, however, and do warrant future investigation.
An Investigation into the Procyclicality of Risk-Based Initial Margin Models

The initial margin requirements for a portfolio of derivatives are typically calculated using a risk model. Common risk models are procyclical: margin requirements for the same portfolio are higher in times of market stress and lower in calm markets. This procyclicality can cause liquidity stress whereby parties posting margin have to find additional liquid assets, often at just the times when it is most difficult for them to do so. Hence regulation has recognised that, subject to being adequately risk sensitive, margin models should not be ‘overly’ procyclical. There is, however, no standard definition of procyclicality. This paper proposes two types of quantitative measure of procyclicality: one that examines margin variation across the cycle and one that focuses on short-term margin increases. It then studies, using historical and simulated data, various margin models with regard to both their risk sensitivity and the proposed procyclicality measures. It finds that models which pass common risk sensitivity tests can have very different levels of procyclicality. The paper recommends that CCPs and major dealers should disclose the procyclicality properties of their margin models, perhaps by reporting the proposed procyclicality measures. This would help derivatives users to anticipate potential margin calls and ensure they have adequate holdings of or access to liquid assets.
A grounded approach to the investigation of assessment practices in built environment undergraduate programmes

Assessment practices in Higher Education (HE) have been undergoing wide-ranging changes over the last number of years and this has been particularly evident in a number disciplines. These changes are in response to a variety of stimuli including a move towards greater accountability, new developments in the use of learning technology and concerns about what graduates need to know, to understand and to be able to do following graduation. The discipline of the Built Environment has been receiving attention in this regard and the validity and effectiveness of traditional modes of assessment have begun to receive consideration. Formative assessment and the use of feedback mechanisms have begun to be recognised as a driving force for enhancing student learning. The above situation is examined in the context of Built Environment undergraduate programmes and discusses the need for a research project in the context of the changing HE educational environment. The aim of such a research project is to help improve the quality of student learning in Built Environment undergraduate programmes. Seminal literature is explored in order to identify, inform and shape the assessment practices of academics. A design is articulated for the research which uses a grounded theory-like approach to conduct the preliminary study. The results of the initial research, when analysed, set out the views and preferences of senior academics and help inform the next stages of this work in progress. The ongoing work anticipates developing a grounded model for the formative assessment of Built Environment undergraduates for the enhancement of student learning.
The applicability of expert systems to risk analysis for waste disposal problems

This report investigates the specificity of expert system tools in view of their application to nuclear waste disposal and related activities. The nature of expert systems and their unique characteristics are first discussed, and several examples are given. The trial and error process used for building them is then outlined. The type of problems they can solve is emphasized. We have chosen one problem, well test interpretation, as an example and begun the development of a prototype system. Upon completion, this program will interpret the pressure versus time curve obtained during a pumping test in order to draw conclusions about the type of hydrologic regime underground and provide an estimate of the relevant hydraulic parameters. The current state of this effort is described, and a listing of the program in LISP and ART languages is given in the appendix. 11 refs., 11 figs.
Protective Effects of Mouse Bone Marrow Mesenchymal Stem Cell Soup on Staurosporine Induced Cell Death in PC12 and U87 Cell Lines

Mouse bone marrow mesenchymal stem cells (mBMSCs) soup is promising tool for the treatment of neurodegenerative diseases. mBMSCs soup is easily obtained and is capable of transplantation without rejection. We investigated the effects of mBMSC soup on staurosporine-induced cell death in PC12 and U87 cells lines. The percentage of cell viability, cell death, NO concentration, total neurite length (TNL) and fraction of cell differentiation (f%) were assessed. Viability assay showed that mBM soup (24 and 48h) in time dependent were increased cell viability (p<0.05) and also cell death assay showed that cell death in time dependent were decreased, respectively (p<0.05). TNL and fraction of cell differentiation significantly were increased compared with treatment1 (p<0.05). Our data showed that mBM Soup protects cells, increases cell viability, suppresses cell death and improvement the neurite elongation. We concluded that Mouse bone marrow mesenchymal stem cell soup plays an important protective role in staurosporine-induced cell death in PC12 and U87 cell lines.
The effect of large-scale magnetic field on outflow in ADAFs: an odd symmetry configuration

We construct self-similar inflow-outflow solutions for a hot viscous-resistive accretion flow with large-scale magnetic fields that have odd symmetry with respect to the equatorial plane in B-theta and even symmetry in B-r and B-phi. Following previous authors, we also assume that the polar velocity v(theta) is non-zero. We focus on four parameters: beta(r0), beta(phi 0) (the plasma beta parameters associated with magnetic field components at the equatorial plane), the magnetic resistivity eta 0 and the density index n = -dln rho/ dln r. The resulting flow solutions are divided into two parts, consisting of an inflow region with a negative radial velocity (v(r) 0. Our results show that stronger outflows emerge for smaller beta(r0) ( 1) and larger values of beta(phi 0), eta(0) and n.
Tailoring interference and nonlinear manipulation of femtosecond x-rays

We present ultrafast x-ray diffraction (UXRD) experiments on different photoexcited oxide superlattices. All data are successfully simulated by dynamical x-ray diffraction calculations based on a microscopic model, that accounts for the linear response of phonons to the excitation laser pulse. Some Bragg reflections display a highly nonlinear strain dependence. The origin of linear and two distinct nonlinear response phenomena is discussed in a conceptually simpler model using the interference of envelope functions that describe the diffraction efficiency of the average constituent nanolayers. The combination of both models facilitates rapid and accurate simulations of UXRD experiments.
