The Effect of Inflation on Domestic Migrant Worker Households in China

Domestic migration workers and inflation are two phenomena attracting attention from worldwide scholars. The article endeavors to accomplish the following three tasks: a) describe the characteristics of inflation and immigration situations in China; b) study the effect of inflation on domestic immigrants' the expenditures; c) understand the effect of inflation on immigrants' happiness and satisfaction. The paper found out that in all the eight expenditure categories, only three categories (food, clothing and housing) are negatively affected by inflation. Other five expenditure categories (health and medical, house equipment, facilities and services, entertainment, educational and cultural activities, transportation and communication, tuition, and miscellaneous) are positively affected by inflation. The biggest reduction of expenditure is in transportation and communication with a coefficient of -0.025. The paper also found out that the lower income group's expenditure is more affected by inflation then higher income group. The paper showed that inflation didn't have a significant effect on people's feeling of happiness and their satisfaction

An Extended Model Of Review Helpfulness: Exploring The Role Of Tie Strength, Perceived Similarity, And Normative Susceptibility

Previous studies on review information evaluation focus on the important roles of two key factors namely argument strength and source credibility but pay less attention to how social influence and social relationship exert impact on this information evaluation behavior. To fill this research gap, based on the similarity – attraction theory and social capital theory, we articulate how source credibility is determined by two social relationship factors: tie strength and perceived similarity. Further, drawing upon the social influence model, we propose that the susceptibility to normative influence intensifies the impact exerted on source credibility by tie strength and perceived similarity. Also, relationships between argument strength and review helpfulness and between source credibility and review helpfulness are both moderated by normative susceptibility. A survey is conducted to test the proposed research model and the results suggest that hypotheses are supported. The results offer important and interesting insights to information systems research and practice

Numerical Study of the Flow Fields in Downburst with Consideration of the Rough Condition on the Ground

The downburst is an extreme weather condition whose resulting load will affect the stability of the building structures. The characteristic of downbursts is required during the design of buildings. In order to achieve the characteristics of the downbursts, large eddy simulation (LES) is adopted. The method impinging jet is used to reproduce the downbursts, meanwhile smooth and rough ground conditions are examined. The setting of the rough layer of the ground is done by using the immersion boundary method (IBM). After the simulation, the wind field is decomposed into the mean component and the turbulence component. In this paper, the radial wind speed profile and the wind speed time diagram of the simulation experiment are compared with the previous measured data and the simulation results. This paper reveals that the radial wind speed is the key part of the downburst wind speed, and it rapidly increases with height. It is also found that the rough ground will cause the peak radial velocity to move up, which is consistent with the change of the main annular vorticity in vortex cloud image analysis. Finally, the turbulence intensity is found to be relatively small at the position where the radial wind speed is relatively large

Numerical Study of the Wake Flow of a Wind Turbine with Consideration of the Inflow Turbulence

Considering the fact that wind turbines operate at the bottom of the atmospheric boundary layer (ABL) where the turbulence is at a high level, and the difficulty of mesh generation in the fully modeled numerical simulation, it is necessary to carry out researches to study the wake flow of wind turbines with consideration of the inflow turbulence. Therefore, a numerical method generating turbulence was proposed and the results show good agreement with those in experiments, based on which the flow fields in the wake of a wind turbine at two tip speed ratios are examined in detail through three actuator methods, namely, ADM, ADM-R and ALM. The performances of these methods were studied and the error sources for each method are clarified. Moreover, the computational efficiency were revealed and the influencing factor for the efficiency is concluded. Besides, the equilibrium relation of the N-S equation in the wake is revealed, which provides a theoretical basis for the optimal arrangement of the wind turbine. It shows that the mean velocity and fluctuating velocity vary greatly near the wind turbine, and become stable gradually away from the wind turbine. The results of ALM method shows the best agreement with the experiment. At near wake region, the turbulent stress term, pressure gradient term and convection term mainly contribute to the equation equilibrium, and convection term is in equilibrium with the turbulent stress term at the far wake

REVISIT THE INFORMATION ADOPTION MODEL BY EXPLORING THE MODERATING ROLE OF TIE STRENGTH: A PERSPECTIVE FROM CONSTRUAL LEVEL THEORY

Previous studies on review information adoption, drawing upon dual process theory, focus on the important roles of two key review-related factors namely argument strength and source credibility, but pay less attention to the social relationships between review sources and recipients. To fill this research gap, based on the construal level theory, we articulate that tie strength moderates the impacts of argument strength and source credibility on content diagnosticity. A survey was conducted to examine the proposed research model and hypotheses and the results showed that the relationship between argument strength and content diagnosticity is stronger when tie strength is weak than when tie strength is strong while the relationship between source credibility is stronger when tie strength is strong than when tie strength is weak. The theoretical and practical implications of the study are also discussed

Advanced Technologies for Oral Controlled Release: Cyclodextrins for oral controlled release

Cyclodextrins (CDs) are used in oral pharmaceutical formulations, by means of inclusion complexes formation, with the following advantages for the drugs: (1) solubility, dissolution rate, stability and bioavailability enhancement; (2) to modify the drug release site and/or time profile; and (3) to reduce or prevent gastrointestinal side effects and unpleasant smell or taste, to prevent drug-drug or drug-additive interactions, or even to convert oil and liquid drugs into microcrystalline or amorphous powders. A more recent trend focuses on the use of CDs as nanocarriers, a strategy that aims to design versatile delivery systems that can encapsulate drugs with better physicochemical properties for oral delivery. Thus, the aim of this work was to review the applications of the CDs and their hydrophilic derivatives on the solubility enhancement of poorly water soluble drugs in order to increase their dissolution rate and get immediate release, as well as their ability to control (to prolong or to delay) the release of drugs from solid dosage forms, either as complexes with the hydrophilic (e.g. as osmotic pumps) and/ or hydrophobic CDs. New controlled delivery systems based on nanotechonology carriers (nanoparticles and conjugates) have also been reviewed
