The impact of beauty vlggers on consumers’purchase behavior

Mestrado Bolonha em MarketingSince smartphones and online social platforms have become popular in China, people'slives have changed significantly, and watching short videos has become an important waytoenjoy leisure and entertainment. Vloggers provide high-quality videos to the Internet-usingpublic and are supported by a growing audience. These videos with Vloggers' thoughtsconsciously or unconsciously affect the behavior and thoughts of the public. As a result, referral advertising by vloggers has gradually become an emerging marketing methodandhasgained more and more attention from brands. The main objective of this paper istoinvestigate the factors that influence consumers' attitudes toward blog recommendations andto try to understand the extent to which consumers' purchase intentions are influencedbyvloggers' attitudes and attitudes toward brands. This descriptive-exploratory study used a single-method quantitative study andanon-stationary convenience sampling technique. Data were collected through anonlinequestionnaire with 243 valid responses. Subsequently, the least squares structural equationmodeling (PLS-SEM) approach was employed using SmartPLS 3.3.3 software. The resultsshow that the perceived benefits and information quality brought by vlog to the publiccansignificantly influence consumers' attitudes toward vlogger’s recommendations andthustoward brands as well. More importantly, they can effectively induce changes in consumers' purchase intentions, including attitudes toward vlogger’s recommendations and attitudestoward brands.Desde que os smartphones e as plataformas sociais online se tornarampopularesnaChina, a vida das pessoas mudou muito, e ver vlogs curtos tornou-se uma forma importantededesfrutar o tempo de de lazer e entretenimento.

Approximation of Sums of Locally Dependent Random Variables via Perturbation of Stein Operator

Let $(X_i, i\in J)$ be a family of locally dependent non-negative integer-valued random variables, and consider the sum $W=\sum_{i\in J}X_i$. We establish general error upper bounds for $d_{TV}(W, M)$ using the three-parametric perturbation form of Stein operator, where the target variable $M$ is either the mixture of Poisson distribution and binomial or negative binomial distribution, and the three parameters are delicately determined by guaranteeing $M$ and $W$ are identical in the first three factorial cumulants. As applications, we discuss in detail the classic local dependence structure examples like $(1, 1)$-runs, ($k_{1},k_{2}$)-runs and $k$-runs, and attain $O(|J|^{-1})$ error bounds under some special cases by exactly figuring out the smoothness of the conditional distributions of $W$ upon partial sums. The obtained result is to some extent a significant improvement of Pek\"{o}z [Bernoulli, 19 (2013)] and Upadhye, et al. [Bernoulli, 23 (2017)]

Construction of Simulation Educational Digital Network Platform in Economics & Management Majors

Along with the informatization and the development of economic globalization, the competition among talent is increasingly intensified; the requirement of position includes both professional foundation theory and strong practical ability. The social integration of economics and management majors is very strong, with the important position in the enterprise and the social economic development. But the social position is determined by the characteristics of professional. Therefore, specialty practice teaching in economics and management majors is particularly important, especially the construction of simulation educational digital network platform in economics & management majors, which will improve the quality of cultivation and promote the strategy of practice teaching according to the characteristics of relative majors. We first analyze the problems in the construction of simulation educational digital network platform in economics & management majors and find what happened in the area. Second, we analyze the function of the platform which is suitable to the majors of economics and management. Third, we introduce the construction of the teaching platform. Finally, we put forward some of the suggestions and countermeasures which are suitable to the development based on the analysis of the problems

How do IT capabilities support fast delivery of big data services to clients across industries?

IT capabilities have been an important research area, especially in the big data era, when much business value can be drawn from external data. This study reports an interesting phenomenon, the transformation of an internal IT department of a traditional manufacturing company into an IT service provider. It adopts the single case study approach to explaining how the newly transformed business unit rapidly delivers IT services to external clients across industries. Results show that the IT service providers can provide fast service delivery to different clients across industries through developing digital assets, bridging business-data and standardizing services/products, which interact with each other. The whole process of service delivery is supported by IT capabilities such as IT infrastructures, IT managerial skills and IT technical skills. We extend the IT capability and IT service provider literature to the big data context

Five-S-isotope evidence of two distinct mass-independent sulfur isotope effects and implications for the modern and Archean atmospheres.

The signature of mass-independent fractionation of quadruple sulfur stable isotopes (S-MIF) in Archean rocks, ice cores, and Martian meteorites provides a unique probe of the oxygen and sulfur cycles in the terrestrial and Martian paleoatmospheres. Its mechanistic origin, however, contains some uncertainties. Even for the modern atmosphere, the primary mechanism responsible for the S-MIF observed in nearly all tropospheric sulfates has not been identified. Here we present high-sensitivity measurements of a fifth sulfur isotope, stratospherically produced radiosulfur, along with all four stable sulfur isotopes in the same sulfate aerosols and a suite of chemical species to define sources and mechanisms on a field observational basis. The five-sulfur-isotope and multiple chemical species analysis approach provides strong evidence that S-MIF signatures in tropospheric sulfates are concomitantly affected by two distinct processes: an altitude-dependent positive 33S anomaly, likely linked to stratospheric SO2 photolysis, and a negative 36S anomaly mainly associated with combustion. Our quadruple stable sulfur isotopic measurements in varying coal samples (formed in the Carboniferous, Permian, and Triassic periods) and in SO2 emitted from combustion display normal 33S and 36S, indicating that the observed negative 36S anomalies originate from a previously unknown S-MIF mechanism during combustion (likely recombination reactions) instead of coal itself. The basic chemical physics of S-MIF in both photolytic and thermal reactions and their interplay, which were not explored together in the past, may be another ingredient for providing deeper understanding of the evolution of Earth's atmosphere and life's origin

Inhibitory Effects of Columbianadin on Nociceptive Behaviors in a Neuropathic Pain Model, and on Voltage-Gated Calcium Currents in Dorsal Root Ganglion Neurons in Mice

Radix angelicae pubescentis (RAP) has been used in Chinese traditional medicine to treat painful diseases such as rheumatism and headache. A previous study has reported that columbianadin (CBN), a major coumarin in RAP inhibits acute and inflammatory pain behaviors. However, the effects of CBN on neuropathic pain behaviors, and the potential underlying mechanism have not been reported. In the present study, the effects of CBN, compared to another major coumarin of RAP osthole (OST), on oxaliplatin-induced neuropathic pain behaviors and on the voltage-gated calcium currents in small dorsal root ganglion (DRG) neurons were studied in mice. It was found that CBN and OST inhibited both mechanical and cold hypersensitivity induced by oxaliplatin. Moreover, CBN and OST might preferentially inhibit T- and L-type calcium currents (Ica). The inhibitory effects of CBN and OST on the oxaliplatin-induced mechanical allodynia were prevented by gabapentin. These results suggest that CBN, as well as OST might inhibit neuropathic pain behaviors through an inhibition of T- and L-type calcium currents in nociceptive DRG neurons
