Understanding the Potential Influence of WeChat Engagement on Bonding Capital, Bridging Capital, and Electronic Word-of-Mouth Intention

As the most prevalent social media platform in mainland China, WeChat enables interpersonal communication among users and serves as an innovative marketing platform for enterprises to interact with consumers. Although numerous studies have investigated the antecedents of electronic word-of-mouth (e-WOM), WeChat users’ specific behaviors still receive limited academic attention. Drawing from social capital theory and social exchange theory, this article develops a model to systematically explore three differentiated types of WeChat behaviors and their association with users’ social capital and e-WOM intention. The conceptual model is explicitly evaluated by utilizing web-based data gathered from 271 young people. Obtained results demonstrate the path effects indicating that: (1) WeChat use behaviors such as seeking, sharing, and liking can positively influence bonding social capital, while only the impacts of sharing and liking on bridging social capital are significant; (2) bonding and bridging social capital are both significant predictors of e-WOM intention, and bonding social capital is the more influential of the two; (3) bonding social capital partially mediates the effect of seeking on e-WOM intention. These findings are eloquent for researchers and operators to further grasp the increasing importance of WeChat adoption and social capital on young generations’ e-WOM intention in the evolving digital age.
Balloon Dacryocystoplasty with Pushed Monocanalicular Intubation as a Primary Management for Primary Acquired Nasolacrimal Duct Obstruction

Given the improvement in the instrument and techniques, novel surgical interventions emerged to avoid the osteotomy from the gold standard dacryocystorhinostomy (DCR) for treating primary acquired nasolacrimal duct obstruction (PANDO). This study’s aim is to compare the surgical outcomes of antegrade balloon dacryocystoplasty (DCP) with pushed monocanalicular intubation (MCI) to balloon DCP alone in patients with complete PANDO. Adult patients with complete PANDO receiving balloon DCP followed by pushed MCI or balloon DCP alone from December 2014 to May 2019 were retrospectively reviewed. A total of 37 eyes of 29 patients were treated with balloon DCP with pushed MCI for 1 month, whereas 35 eyes of 28 patients were treated with balloon DCP alone. The success rates at 1 month, 3 months, and 6 months after operation were 89.2%, 73.0%, and 70.2%, respectively, in balloon DCP with MCI group, and 62.9%, 62.9%, and 60.0%, respectively, in the balloon DCP alone group. The balloon DCP with pushed MCI group had a better success rate but only reached statistical significance at 1 month postoperatively (p < 0.01). Subgroup analysis was performed based on age. The success rate in those under 65 in the combined balloon DCP with MCI group was significantly higher than in balloon DCP alone group (72.7% vs. 9.1%, p = 0.004), whereas there was no significant difference between those aged at least 65 in the combined group and the balloon DCP alone group (69.2% vs. 83.3%, p = 0.2). Conclusively, there was no significant difference in the success rate between antegrade balloon DCP with and without pushed MCI in general. Nevertheless, the former procedure was associated with significantly higher surgical success rate than the latter in younger patients.
Adaptive multimodal surface patterning on a cylindrical shell panel using piezoelectric actuators

Abstract The present study demonstrates the feasibility of creating adaptive multimodal surface patterns on an otherwise featureless cylindrical shell surface with the help of surface-bonded piezoelectric actuators. These patterns can be tuned to transform into a periodic shape that spreads equally over the domain or can have the form of a localized dimple that is concentrated only over a portion of the domain of the structure. The possibility of controlling the number, location, and temporal order of these patterns by smart actuation is established. This tunability, in both topographic patterns and their feature locations, can offer dynamic and switchable functionalities for fruitful applications.

Evolution of complex modulus and higher harmonics of stress response of asphalt concrete in strain-controlled four-point beam fatigue tests

ABSTRACT The modulus of asphalt concrete that is conventionally obtained from large amplitude oscillations (LAOs) in fatigue tests cannot be considered a material property since the response changes from cycle to cycle. It is necessary to determine how viscoelastic properties vary with the extent of damage, and they cannot be obtained from LAOs without making specific constitutive assumptions. Moreover, the higher harmonics of the stress response can be used to quantify the distortion of the stress waveform and, therefore, the point of failure in fatigue tests. This should also be explored further. With these as the objectives, strain-controlled four-point bending (4PB) tests were conducted in this study with the LAOs regularly interrupted to apply a few cycles of small amplitude oscillations (SAOs). The stress response from both SAOs and LAOs were subjected to Fourier analysis. The fundamental harmonic was used to define the apparent storage and loss moduli, and the moduli from the SAOs and LAOs were compared with each other. The ratio of the amplitude of the third harmonic to the first harmonic was found to sharply increase after a certain point in the test. This was used to define a new failure criterion for 4PB fatigue tests.
Linking Atmospheric Cloud Radiative Effects and Tropical Precipitation

Studies in recent decades have demonstrated a robust relationship between tropical precipitation and column relative humidity (CRH). The present study identifies a similar relationship between CRH and the atmospheric cloud radiative effect (ACRE) calculated from satellite observations. Like precipitation, the ACRE begins to increase rapidly when CRH exceeds a critical value near 70%. We show that the ACRE can be estimated from CRH, similar to the way that CRH has been used to estimate precipitation. Our method reproduces the annual mean spatial structure of the ACRE in the tropics, and skillfully estimates the mean ACRE on monthly and daily time scales in six regions of the tropics. We propose that the exponential dependence of precipitation on CRH may be partially explained by cloud‐longwave feedbacks, which facilitate a shift from convective to stratiform conditions.
Understanding the Digital Platform Economy: Effect of Airbnb on Housing in Indian Cities

ABSTRACT This article answers the question: What is the effect of Airbnb on rents and housing prices? Based on theory and empirical evidence, we expect that in cities where Airbnb is active, rental accommodation and housing would be relatively more expensive. This is because we assume that such units were withdrawn from the housing market and excess capacity of houses can be used. We distinguish between the rents of one- , two- , and three-bedroom apartments, in addition to housing prices in major Indian cities. Accounting for the endogeneity of Airbnb density, we find that the Airbnb density has a significant effect in terms of raising rents of apartments of different sizes as well as increasing housing prices. The magnitude of our estimates implies an increase of up to 0.08% in the rent of two-bedroom apartments, 0.14% in the rents of three-bedroom apartments, and 0.39% in housing prices per square foot, for every 1-percentage-point increase in Airbnb density. These effects are higher than those found in some existing studies, but lower than those found by others. The policy implications of the research and caveats of the data and research are summarized.

Computer Modeling of the Heart for ECG Interpretation—A Review

Computer modeling of the electrophysiology of the heart has undergone significant progress. A healthy heart can be modeled starting from the ion channels via the spread of a depolarization wave on a realistic geometry of the human heart up to the potentials on the body surface and the ECG. Research is advancing regarding modeling diseases of the heart. This article reviews progress in calculating and analyzing the corresponding electrocardiogram (ECG) from simulated depolarization and repolarization waves. First, we describe modeling of the P-wave, the QRS complex and the T-wave of a healthy heart. Then, both the modeling and the corresponding ECGs of several important diseases and arrhythmias are delineated: ischemia and infarction, ectopic beats and extrasystoles, ventricular tachycardia, bundle branch blocks, atrial tachycardia, flutter and fibrillation, genetic diseases and channelopathies, imbalance of electrolytes and drug-induced changes. Finally, we outline the potential impact of computer modeling on ECG interpretation. Computer modeling can contribute to a better comprehension of the relation between features in the ECG and the underlying cardiac condition and disease. It can pave the way for a quantitative analysis of the ECG and can support the cardiologist in identifying events or non-invasively localizing diseased areas. Finally, it can deliver very large databases of reliably labeled ECGs as training data for machine learning.

Djamil Hospital Padang.Results: The mean BDNF levels of pregnant women with preeclampsia were 519.9± 325.4 pg/ml. The correlation between BDNF and systolic blood pressure, diastolic blood pressure, and Mean Arterial Pressure was negatively correlated (r = -0.145, -0.1, and -0.218), with a weak correlation. There was no statistically significant relationship between BDNF and systolic blood pressure, diastolic blood pressure, and mean arterial pressure (p> 0.05). BDNF correlation with infant birth weight and the birth length was positively correlated (0.196 and 0.205) with a weak correlation. The correlation between BDNF level and Apgar score was negatively correlated (-0.039 and -0.054) with a weak correlation. There was no statistically significant correlation between BDNF with birth weight, birth length, and Apgar score (p> 0.05). Conclusion: The mean BDNF level in preeclampsia was lower than normal pregnancy, there was a negative correlation between BDNF levels and maternal outcomes in preeclampsia with a weak correlation. There was a positive correlation between BDNF levels and perinatal outcomes (birth weight and birth length) in preeclampsia and there was a negative correlation between BDNF levels and Apgar score in preeclampsia with a weak correlation.Keywords: Brain Derived Neurotrophic Factors, Preeclampsia, Maternal Outcome, Perinatal Outcome
Solitary wave diffraction around a concentric porous cylindrical structure in front of a vertical wall

This paper investigates solitary wave diffraction around concentric porous cylindrical structure in front of a vertical wall, where the exterior cylinder is permeable and the interior cylinder is impermeable. This problem is transformed into an issue of bi-directional incident waves diffraction around two concentric cylindrical systems based on the image theory. An analytical solution of the problem is obtained by applying the eigenfunction expansion approach and Graf's addition theorem. Unlike previous studies using Airy wave, this paper uses solitary wave as incident wave. The hydrodynamic loads and wave elevations on the concentric cylindrical system are calculated and compared with existing work. An excellent agreement is obtained between the model and data. Parametric studies on porosity, annular spacing, incident wave angle, distance between the concentric structure and wall were also explored. The results indicated that wave loads on the exterior cylinder near a vertical wall could reach twice as large as the force on it in open water, while the magnitudes of wave loads on the interior cylinder are similar for the two cases. In addition, we compared the modelling results of wave surface elevations using solitary wave and Airy waves. It shows that the amplitude of the wave surface elevations caused by the solitary wave is significantly higher than that of the Airy wave, which means the wave effects on offshore structures will be underestimated when using the Airy wave model in the same shallow water conditions.
Effect of Potassium Permanganate and Silver Nitrate Chemicals on the Shelf Life of Guava Fruits

Under ambient conditions, fruit quality is maintained only for 2 to 3 days after harvest because of high moisture content, soft skin. Guava fruits have higher rate of respiration, transpiration, ripening and other biological activities even after harvest which deteriorate the quality of fruits in a short period of time which makes them unmarketable. Hence it is necessary to reduce rates of these physiochemical changes in order to enhance the shelf life of guava fruits. Various methods of extending shelf life of the fresh guava fruits have been experimented and recommended for different varieties viz. cold storage, temperature modification, skin coating with wax, use of plant growth regulators, chemical treatments, packaging materials and ethylene absorbent. The response of the guava fruits to these treatments varies with different varieties and conditions to be stored. Hence it may be necessary to find out a suitable technology for International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 6 Number 8 (2017) pp. 987-992 Journal homepage: http://www.ijcmas. com
Why corporate board insiders
 still
 matter: Evidence using aggregate earnings shocks

Corporate governance research lacks clarity on why, when, and what types of firms appoint non-CEO board insiders because of the primary academic focus on board independence. While executive monitoring is relevant, it is equally salient to understand why firms appoint non-CEO insiders to the boards. This concern is especially relevant when firms face financial difficulties during periods of macro hardship. Using the corporate socialization theory, we suggest that board insiders likely generate firm-specific private information by utilizing their long-tenured firm-focused corporate experience. It would result in a unique form of non-fungible expertise that firms would find valuable during macro hardships. Employing a difference-in-difference research design, consistent with our theory, we document that when firms experience a cross-country macro hardship such as an aggregate earnings shock , they appoint long-tenured and firm-focused non-CEO board insiders. We further show that financially distressed firms have a higher demand for such directors.
Hygroscopic properties of potassium-halide nanoparticles

ABSTRACT The hygroscopic properties of KBr, KCl, and KI nanoparticles having diameters from 8 to 60 nm were measured using a tandem Differential Mobility Analyzer. In all cases, the deliquescence and efflorescence relative humidity values increased with decreasing particle diameter. The associated growth factors also decreased with decreasing particle diameter, in agreement with predictions by Köhler theory. Overall, the theoretically predicted growth factors agreed well with the measurements, i.e., within ±3% uncertainty. For KCl particles having sizes down to 15 nm, however, a dynamic shape factor of 1.08, corresponding to non-spherical crystalline particles prior deliquescence, was inferred for agreement between measurements and theory. By comparison, KBr and KI within the same size range warranted shape factors of unity, equivalent to a sphere. These results contribute to an understanding of nanosize behavior widely relevant to material sciences as well as atmospheric aerosol particles over the oceans.
Programmed cell death in the coccoid green microalga Ankistrodesmus densus Korshikov (Sphaeropleales, Selenastraceae)

Abstract Reports of programmed cell death (PCD) across the taxonomic spectrum of photosynthetic unicellular organisms raise questions concerning its ecological and evolutionary roles. However, prior to ecological studies or evolutionary interpretations, it is essential to document phenotypic changes associated with PCD at the single-cell level, since death-related responses vary between taxa and within a single taxon depending on environmental stimuli. Here, we report responses to rapidly changing light, temperature and fluctuations in macronutrients in the model selenastracean green microalga Ankistrodesmus densus (Chlorophyta, Chlorophyceae, Sphaeropleales). We used stringent, but environmentally appropriate, conditions of prolonged darkness, nitrogen starvation (4 days), heat (1 h at 44°C) and cold shock (3 h at 2 ± 2°C). PCD phenotypes were examined by ultrastructural changes, phosphatidylserine (PS) externalization and DNA degradation. Flow cytometric Annexin V FITC analyses revealed that darkness and nitrogen-deprived cultures had significantly higher proportions of cells with PS externalization compared with controls (p < 0.05). Heat and cold treatments did not affect PS externalization (p = 0.44 and p = 0.99, respectively). Transmission electron microscopy (TEM) of light-deprived cells demonstrated, among other ultrastructural changes, marked cytoplasmic vacuolization suggesting a subtype of PCD known as vacuolar cell death. Nitrogen-starved cells had less vacuolization but presented more typical ultrastructural markers of PCD such as chromatin condensation and marginalization. In contrast, the more severe heat and cold shock treatments resulted in necrotic-like features. These findings suggest that prolonged darkness and nitrogen starvation induce PCD in a small (8.4 3.5 and 7.42 2.6%, respectively) but significant (p < 0.05) fraction of the A. densus population. Documenting these different death-related phenotypes depending on different environmental inducers is essential for interpreting ecological studies. Furthermore, our data support the hypothesis that autophagic/vacuolar cell death (VCD), which is central to organism homeostasis in plants (Streptophyta), occurs in Chlorophyta. VCD probably arose long before the evolution of multicellularity in plants. HIGHLIGHTS Darkness and nitrogen deprivation induce different programmed cell death markers in Ankistrodesmus densus; Plant vacuolar-like cell death occurs in Chlorophyta; There is crossover between the vacuolar and apoptosis-like death morphotypes.
