Local-province chief executive officer and managerial myopia: Evidence from China.

Managerial myopia occurs when executives value short-term benefits to the extent that firm long-run development will be obstructed. Recent studies have shown that the locality effect plays an important role in managerial myopia-local United States chief executive officers (CEOs) who work near their home states are less likely to behave myopically because of more effective monitoring and greater reputation concern. In an emerging market, government policies play a more important role in the strategic planning enterprises.

Marketing by live streaming: How to interact with consumers to increase their purchase intentions.

Live streaming e-commerce, as a kind of new information technology-based business model, is currently the most popular marketing approach, especially in China. This research divides live streaming interactions into three dimensions, interactions for obtaining product information (IPI), interactions for grasping the purchase dynamics of others (IPD), and interactions for obtaining monetary incentives (IMI), and proposes a comprehensive framework to examine whether live streaming interactions with consumers promote both social presence and consumer conformity, and thereby enhance their purchase intentions. Covariance-based structural equation modeling (CB-SEM) with AMOS was conducted to analyze data collected from 576 Chinese consumers.

Preparation of Polyvinyl Imine Modified Carbon Quantum Dots and Their Application in Methotrexate Detection.

Understanding the Inequality of Web Traffic and Engagement in Online Healthcare Communities.

The online healthcare community (OHC) is a kind of doctor-patient communication platform, in which doctors can share medical knowledge and provide various kinds of counsel for patients. However, if the OHC's web traffic is concentrated on a small number of doctors, or if only a few doctors are actively involved in the OHC's activities, this will not be conducive to the optimal development of the OHC. This study explores this issue of inequality and makes three main innovations.

Impacts of physician promotion on the online healthcare community: Using a difference-in-difference approach.

In this study, we use a difference-in-difference approach to explore how physician promotion, the advancement of a physician's offline reputation, affects patient behavior toward physicians in online healthcare communities; this allows us to explore how patients interpret the signals created by physician promotion. The study sample was collected from over 140,000 physician online profiles after 25 months of continuous observation, with 280 physicians who were promoted at month 13 as the treatment group and a control group obtained by propensity score matching. Our results show that a physician's promotion causes more patients to choose that physician, makes patients willing to give more psychological rewards, and makes them tend to give that physician a higher online rating.

NeuRec: Incorporating Interpatient prior to Sparse-View Image Reconstruction for Neurorehabilitation.

Medical imaging technologies such as computed tomography (CT) and magnetic resonance imaging (MRI) imaging are indispensable for contemporary neurorehabilitation diagnostics, intervention, and monitoring. It would be desirable to reconstruct images from sparse measurements to reduce the ionizing radiation and motion artifacts. Although recent coordinate-based representation methods have shown promise advances for sparse-view reconstruction, they overfit a single MLP on a single patient.

Optimal decisions for green supply chain with a risk-averse retailer under government intervention.

This paper investigates the effects of the financial subsidy and product access policies on the performance of green supply chains (GSCs). Based on the game theory and preference theory, we study a green supply chain consisting of a risk-neutral manufacturer and a risk-averse retailer under government interventions from different power structures. The result reveals that green production can be effectively promoted only when product access exceeds a certain threshold.

Effect of soybean protein isolate-pectin composite nanoparticles and hydroxypropyl methyl cellulose on the formation, stabilization and lipidolysis of food-grade emulsions.

The formation and stabilization mechanism as well as digestion characteristics of food-grade emulsions prepared by the SPNPs-HPMC mixed systems (a combination of soybean protein isolate-pectin composite nanoparticles (SPNPs) and hydroxypropyl methylcellulose (HPMC)) were investigated. Then, it was found that the SPNPs-HPMC mixed systems could not only enhance the stability of the emulsion, but also make it have a satisfactory lipidolys is efficiency. During the formation and stabilization of the emulsion, HPMC was adsorbed in the early stage of emulsion formation, while SPNPs needed a longer adsorption time.

Study on the Macroeconomic Model Based on the Genetic Algorithm.

In order to design a more reliable general push time cycle prediction software for macroeconomic indicators, a set of general software is used to serve financial transactions, bulk material transactions, international trade, macro-control and other fields, so as to improve the prediction of macroeconomic indicators. Because the macro data is one-dimensional array data, the essence of the mutation algorithm is to obtain the movement direction of the mutation of data nodes, obtain the distance between the linear programming result and the original data through the least square method, and calculate the average value in the original data, After binary -correction, it refers to the binary -correction results of the one-dimensional matrix before the final evaluation output factor and the one-dimensional matrix after the final evaluation output factor. In this study, genetic algorithm is introduced as the core algorithm.

Silver ions involved fluorescence "on-off" responses of gold nanoclusters system for determination of carbendazim residues in fruit samples.

Herein, a fluorescence "on-off" system was developed for monitoring carbendazim (CBZ) residues in fruit samples, based on glutathione-gold nanoclusters (GSH-Au NCs) and silver ions (Ag). First, the fluorescence intensity of GSH-Au NCs was greatly enhanced (turn on) with aggregation-induced emission enhancement (AIEE) effect in the presence of Ag, then fluorescence quenching occurred (turn off) with adding CBZ by the chelation between CBZ and Ag. The quenching degree was well linearly dependent on CBZ concentration covering from 0.
