Modular Properties of 3D Higher Spin Theory

In the three-dimensional sl(N) Chern-Simons higher-spin theory, we prove that the conical surplus and the black hole solution are related by the S-transformation of the modulus of the boundary torus. Then applying the modular group on a given conical surplus solution, we generate a 'SL(2,Z)' family of smooth constant solutions. We then show how these solutions are mapped into one another by coordinate transformations that act non-trivially on the homology of the boundary torus. After deriving a thermodynamics that applies to all the solutions in the 'SL(2,Z)' family, we compute their entropies and free energies, and determine how the latter transform under the modular transformations. Summing over all the modular images of the conical surplus, we write down a (tree-level) modular invariant partition function.Comment: 51 pages; v2: minor corrections and additions; v3: final version, to appear in JHE

Factores en el acoso cibernético: el modelo de actitud-influencia social-eficacia

This study examines the correlation between risk perception, knowledge, social influence, self-efficacy, and cyber bullying behavior from the perspective of the attitude-social influence-efficacy model. The samples in this survey are adolescents who have had cyber bullying behavior or have witnessed their peers’ cyber bullying behavior. The results showed that attitude towards cyber bullying affected cyber bullying intention, and that intention also influenced cyber bullying behavior. Social influence also had an impact on cyber bullying intention and cyber bullying behavior. In fact, intention was a mediator between attitude and behavior, as well as between social influence and behavior. Este estudio examina la correlación entre la percepción de riesgo, el conocimiento, la influencia social, la autoeficacia y el comportamiento del acoso cibernético desde la perspectiva del modelo de influencia social. Las muestras en esta encuesta son adolescentes que han tenido un comportamiento de acoso cibernético o han presenciado el comportamiento de acoso cibernético de sus compañeros. Los resultados mostraron que la actitud hacia el acoso cibernético afectó la intención de acoso cibernético, y esa intención también influyó en el comportamiento del acoso cibernético. La influencia social también tuvo un impacto en la intención de acoso cibernético y el comportamiento de acoso cibernético. De hecho, la intención era un mediador entre la actitud y el comportamiento, así como entre la influencia social y el comportamiento

Absorptive Capacity And MNC Knowledge Transfer: The Organizational Behavior Perspective

Many previous studies on internal knowledge transfer in multinational corporations (MNCs) have indicated that organizational absorptive capacity (AC) has a significant effect on knowledge transfer, but few scholars have dwelt on employee absorptive capacity. Employee AC is fundamental to organizational AC. Therefore, employee AC is an important management issue. From an organizational behavior perspective, this study attempted to explore whether employees personality traits, job characteristics and organizational environment had an impact on their absorptive capacity, hoping to develop a new research direction for the AC research realm

The Effect Of Blog Trustworthiness, Product Attitude, And Blog Involvement On Purchase Intention

Consumers value the advice of others when they are shopping online. Therefore, some high pageview bloggers could have a great influence on a consumer’s shopping decision. Blog marketing is a new communication tool. “Blog trustworthiness”, “product attitude” and “blog involvement” were the three independent variables used in this study to investigate the aspect of purchase intention. This study found that blog involvement had a significant influence on purchase intention. This result contributes concrete suggestions to enterprises when they are dealing with blog marketing

From OEM Supplier To A Global Leading Company

Firms in developing countries generally have lower technological and marketing capabilities compared to firms in developed countries. Joining OEM alliances can help firms with fewer capabilities to learn from their partners and then upgrade their technological capabilities. In this kind of scenario, learning firms in OEM alliances are usually from developing countries, and they play the role of suppliers; on the other hand, teaching firms are usually from developed countries and play the role of buyers. Although OEM alliances provide a platform for acquiring, transferring and creating knowledge, few suppliers can sufficiently upgrade their technological capabilities to reach a higher level and develop marketing capabilities in order to complete in the global market. Therefore, it is an important issue to know how an OEM supplier from developing countries can become a leading firm in the global market. In this study, we choose Giant Bicycles to explore this issue. We conduct a case study to explore the growth of Giant Bicycles from an OEM supplier to a leading company in the bicycle industry

Critical Care of Acute Heart Failure

Acute heart failure is a life-threatening medical condition. Improving acute heart failure care is important. Early diagnosis and evaluating the etiology are important in acute heart failure. Patients with suspected acute heart failure should have a diagnostic workup, and appropriate pharmacological and nonpharmacological management should be started promptly and in parallel. Diagnosis of acute heart failure should be based on history and symptoms. The physical examination typically presents with some combination of increased congestion and decreased peripheral perfusion, further confirmed by electrocardiogram, chest radiograph, biomarkers, and echocardiogram. The first step in the management of a patient is to address life-threatening issues. Patients with respiratory failure or cardiogenic shock should be treated soon. The next step is the identification of precipitants that needs urgent management. Evidence-based medication to reduce morbidity and mortality for patients with heart failure includes an angiotensin converting enzyme inhibitor, angiotensin receptor blocker, or angiotensin receptor-neprilysin inhibitor; a beta blocker; and a mineralocorticoid receptor antagonist. During an acute heart failure episode, management of these agents depends upon whether the patient has contraindications to therapy such as hemodynamic instability or acute kidney injury. Once the patient is stable, therapies are carefully initiated, reinitiated, or titrated with appropriate follow-up

NNVA: Neural Network Assisted Visual Analysis of Yeast Cell Polarization Simulation

Complex computational models are often designed to simulate real-world physical phenomena in many scientific disciplines. However, these simulation models tend to be computationally very expensive and involve a large number of simulation input parameters which need to be analyzed and properly calibrated before the models can be applied for real scientific studies. We propose a visual analysis system to facilitate interactive exploratory analysis of high-dimensional input parameter space for a complex yeast cell polarization simulation. The proposed system can assist the computational biologists, who designed the simulation model, to visually calibrate the input parameters by modifying the parameter values and immediately visualizing the predicted simulation outcome without having the need to run the original expensive simulation for every instance. Our proposed visual analysis system is driven by a trained neural network-based surrogate model as the backend analysis framework. Surrogate models are widely used in the field of simulation sciences to efficiently analyze computationally expensive simulation models. In this work, we demonstrate the advantage of using neural networks as surrogate models for visual analysis by incorporating some of the recent advances in the field of uncertainty quantification, interpretability and explainability of neural network-based models. We utilize the trained network to perform interactive parameter sensitivity analysis of the original simulation at multiple levels-of-detail as well as recommend optimal parameter configurations using the activation maximization framework of neural networks. We also facilitate detail analysis of the trained network to extract useful insights about the simulation model, learned by the network, during the training process.Comment: Published at IEEE Transactions on Visualization and Computer Graphic

Asic3−/− Female Mice with Hearing Deficit Affects Social Development of Pups

BACKGROUND: Infant crying is an important cue for mothers to respond adequately. Inappropriate response to infant crying can hinder social development in infants. In rodents, the pup-mother interaction largely depends on pup's calls. Mouse pups emit high frequency to ultrasonic vocalization (2-90 kHz) to communicate with their dam for maternal care. However, little is known about how the maternal response to infant crying or pup calls affects social development over the long term. METHODOLOGY/PRINCIPAL FINDINGS: Here we used mice lacking acid-sensing ion channel 3 (Asic3(-/-)) to create a hearing deficit to probe the effect of caregiver hearing on maternal care and adolescent social development. Female Asic3(-/-) mice showed elevated hearing thresholds for low to ultrasonic frequency (4-32 kHz) on auditory brain stem response, which thus hindered their response to their pups' wriggling calls and ultrasonic vocalization, as well as their retrieval of pups. In adolescence, pups reared by Asic3(-/-) mice showed a social deficit in juvenile social behaviors as compared with those reared by wild-type or heterozygous dams. The social-deficit phenotype in juvenile mice reared by Asic3(-/-) mice was associated with the reduced serotonin transmission of the brain. However, Asic3(-/-) pups cross-fostered to wild-type dams showed rescued social deficit. CONCLUSIONS/SIGNIFICANCE: Inadequate response to pups' calls as a result of ASIC3-dependent hearing loss confers maternal deficits in caregivers and social development deficits in their young
