The Nexus Between IT Capabilities and Firm Innovation Performance: The Mediating Effect of Supply Chain Agility
No full textThis study investigates the impact of IT capabilities on firm innovation performance. Further, it examines the mediating role of supply chain agility (SCA) as well as the moderating effect of innovation orientation (IO). The proposed conceptual model draws on resource-based view (RBV) theory. Dataset of 335 responses was analysed with process MACRO using SPSS 24.0 and AMOS. The findings show that IT capabilities positively affect firm innovation performance and SCA mediates the relationship of IT capabilities and firm innovative performance. Finally, results also confirm the moderating effect of IO between the IT capabilities and SCA
Chinese calligraphic handwriting practice promotes positive affect in adolescents: Converging evidence from correlational and experimental designs
No full textChinese calligraphic handwriting (CCH) practice has proven to be beneficial to several aspects of psychological health and has been considered a complementary therapy for mental disorders. However, less is known about whether CCH practice benefits an individual\u27s positive affect, a core component of affective well-being. Therefore, we examined this question in Chinese adolescents by combining correlational and experimental methods. In Study 1 (N = 1460), we found that high school students who practiced CCH had higher positive affect in their daily lives than those who did not practice CCH. In Study 2, a training experiment was conducted with college students, who were randomly assigned to receive either CCH training or no treatment. A six-day short-term CCH training led to a significant benefit in positive affect in the training group (N = 23) relative to the control group (N = 27). Together, our study provides converging evidence that CCH practice can promote positive affect in adolescents, further supporting the promotion of CCH in mental health practice
CEOs’ multicultural backgrounds and firm innovation: Evidence from China
No full textWe examine the effect of CEOs’ multicultural backgrounds, which play a critical role in shaping an individual\u27s personality, on firms’ innovation outputs. Employing the number of dialects in a CEO\u27s birthplace as a proxy for cultural diversity, we focus on language-related cultural influence while controlling for experience-related cultural influence. Our hypothesis posits that the multicultural background makes the CEO more open-minded and adventurous and, therefore, more likely to invest in firm innovation. We find that CEOs with multicultural backgrounds devote more effort to and perform better on innovation than those without multicultural backgrounds. Cross-sectional analyses show that this positive effect of CEOs’ multicultural backgrounds on innovation output is more pronounced when the firm is exposed to higher industry competition and when the information environment is more transparent. Our findings contribute to the literature on CEO characteristics by providing evidence of how the CEO\u27s multicultural background induces alterations in the firm\u27s innovation effort and performance
Biochar Enhances Soil Resource Availability and Suppresses Microbial Metabolism Genes in the Rhizosphere of Wheat
No full textDespite the well-documented role of biochar in promoting soil quality and crop productivity, the underlying biological mechanisms remain poorly understood. Here, we explored the effects of straw biochar on soil microbiome in the rhizosphere from wheat using metagenomic sequencing. Our results showed that straw return decreased the yields of wheat, while the straw biochar return increased the wheat yields. Further, both the richness and community composition confirmed different effects of the straw return and straw biochar return. The straw biochar return also resulted in greater rhizosphere effects from wheat, represented by resource availability, including soil organic carbon, soil total nitrogen, available phosphorus, and available potassium. The rhizosphere effects from wheat, represented by microbial metabolism genes involved in carbon, nitrogen, phosphorus, and potassium cycling, however, were decreased by straw biochar returning. In addition, the rhizosphere effects from nitrogen content and the nitrogen cycling genes showed negative relationships with wheat yields. Together, these results revealed that straw biochar enhanced soil resource availability but suppressed microbial metabolism genes in the rhizosphere from wheat, supporting the idea that straw biochar serves as a nutrient pool for crops
Dynamic Multiple-Message Broadcast: Bounding Throughput in the Affectance Model
No full textWe study a dynamic version of the Multiple-Message Broadcast problem, where packets are continuously injected in network nodes for dissemination throughout the network. Our performance metric is the ratio of the throughput of such protocol against the optimal one, for any sufficiently long period of time since startup. We present and analyze a dynamic Multiple-Message Broadcast protocol that works under an affectance model, which parameterizes the interference that other nodes introduce in the communication between a given pair of nodes. As an algorithmic tool, we develop an efficient algorithm to schedule a broadcast along a BFS tree under the affectance model. To provide a rigorous and accurate analysis, we define two novel network characteristics based on the network topology and the affectance function. The combination of these characteristics influence the performance of broadcasting with affectance (modulo a logarithmic function). We also carry out simulations of our protocol under affectance. To the best of our knowledge, this is the first dynamic Multiple-Message Broadcast protocol that provides throughput guarantees for continuous injection of messages and works under the affectance model
Critical points and stability analysis in MHD radiative non-Newtonian nanoliquid transport phenomena with artificial neural network prediction
No full textIn the present framework, flow and thermal transport behavior of non-Newtonian viscoelastic fluid induced by stretching/shrinking of the horizontal sheet under the influence of Lorentz force, volumetric heat source/sink, and radiation (assuming optically thick medium) has been investigated. Multiple solutions (Branches) have been predicted numerically using Lie symmetry transformation and Runge Kutta Dormand Prince (RKDP) algorithm-based Shooting method for the different controlling parameters, stretching/shrinking (Formula presented.), and suction (Formula presented.) with substantial impact with UCM parameter, (Formula presented.). Some of the results have also been compared with MATLAB built-in solvers to validate our in-house code. The deviations in critical (turning) points (Formula presented.) have been noticed for different values of (Formula presented.) and (Formula presented.). The temporal stability analysis is performed for these parameters (Formula presented.), and the upper (lower) branch is only physically feasible (infeasible). The combined effect on Nusselt number and skin-friction coefficient is also depicted in the form of contour plots. The outcomes from artificial neural network (ANN) using Levenberg-Marquardt algorithm give a preferred estimate for current numerical simulation. In ANN prediction, the optimal number of neurons in the hidden layer is used, having minimum value of RMSE and RMRE with maximum (Formula presented.) for different cases of non Newtonian stretching/shrinking sheet. Finally, the results conclude that the applied ANN model can accurately predict the output results
Quadrupedal Movement Training: A Brief Review and Practical Guide
No full textApply It! • Evidence suggests quadrupedal motor control mechanisms aid in balance and coordination during bipedal tasks. • Quadrupedal movement training provides participants with opportunities to improve total body joint stability patterns by altering the base of support and center of mass through stationary and traveling variations. • Electromyographic studies on crawling movements in adults have shown substantial muscle activity in the trunk stabilizers and other supporting muscles such as the shoulders, triceps, quadriceps, calves, and hamstrings. The center of mass location changes the pattern of muscle activation in relation to the distribution of the load. • Promising evidence suggests that quadrupedal movement training may improve joint proprioception and range of motion
