Purpose Based on the knowledge-based view, this study investigates how firms' information technology (IT) capability broadens and deepens their knowledge base, which consequently improves digital innovation. By further drawing institutional theory perspective, examines relationships between IT base are moderated by environments in firm operates. Design/methodology/approach This paper uses 170 samples of Chinese firms an empirical test conducted authors following a hierarchical regression...

On the basis of framing effect and protective action decision model, this study examines differences in people's response to diverse hazard onset types (sudden or gradual) under different cultural frameworks (China United States) effects culture type on perception behavioral response. The data are derived from three questionnaire surveys H7N9 smog emergency China H1N1 States. Results indicate that people with cultures contexts present substantial risk perception, stakeholder expectations....

Motivated by recent work studying massive functional data, such as the COVID-19 we propose a new dynamic interaction semiparametric function-on-scalar (DISeF) model. The proposed model is useful to explore among set of covariates and their effects on response. includes many important models investigated recently special cases. By tensor product B-spline approximating unknown bivariate coefficient functions, three-step efficient estimation procedure developed iteratively estimate...

Motivated by applications, we propose a class of dynamic single-index varying-coefficient models to explore the varying interaction effects on response variable among set covariates.That is say, are allowed change with some factors interest, such as time, spatial location, or other covariates.A spline-based approach developed estimate index and functions.The convergence rates asymptotic normalities resulting estimators established.It also shown that exhibit an oracle property.A penalized...

Covid-19 detection in food is an effective solution to ensure the accurate rate of Covid-19. The difficulties and methods virus safety feasibility digital PCR technology are analyzed. main parameters characteristics dPCR other technologies compared. application viruses pathogenic bacteria, preparation purity verification RNA reference material, steps testing were expounded. Compared with traditional methods, has great advantages limit stability. will develop towards high flux automation,...

The change of cut tobacco structure before and after distributing was analyzed with principal component analysis to evaluate the performance distributors two different types. results showed that: 1) quality distributed by a multi-rotating-drum distributor changed less than that disc distributor,and cigarette making machines more uniform; 2) cluster intercept calculation via could difference between products.

Base on system engineering theory, traditional optical design optimization is developed. General global optimization, which based central optics integrated with up-to-date comprehensive modules and methods in created way, presented supported by abundant results of research development, especially multiple configuration optimization.

Most E-business take the traditional distribution as cooperating with third-party logistics, which could lower cost but make company risk more. Such they accelerat delivery speed couldn't control attitude of man. A Chinese corporation innovates "procurement service" model to solve problem effectively. This article will introduce workflow firstly, then analysize innovated and conclude significance all B2C companies. The whole paper cooperation a high school example.

This study focuses on the investigation of influence human capital factors tax collection efficiency. Literature review indicated that although efficiency evaluation has been discussed in previous study, seldom addressed. Hence, Data Envelopment Analysis (DEA) method employed to address this issue study. The innovation lays have taken into account collection. To measure performance collection, a case Wuhan city, China carried out. DEA analysis results demonstrate increases with increase...

To breakthrough the choke point on an optics and photonics system research development, to achieve thorough optimization system, approach theoretical limited, upgrade innovation ability. Advanced global methods are studied systematically in a great level. The three main elements of optimization, that is model parameterization, algorithm merit function, base this, relationship among them their reciprocity defined analyzed detail.
