Intercultural Communication between Home Students and International Students
Research has consistently shown that international students have reported experiencing difficulties socializing with home students, feeling alienated and lonely, and wanting to have more local friends. A substantial body of research has studied international students’ intercultural communication experience with home students. However, since host society and social interaction with home nationals are important factors influencing international students’ acculturation, it is important to study intercultural communication from home students’s perspective. This literature review aims to discuss the limitations and gaps in intercultural communication literature and provide an overview of research pertaining to anxiety-uncertainty, ethnocentrism, intercultural communication competence, and intercultural contact
East Asian International Students\u27 Interdependent Happiness: The Role of Acculturative Stress, Dialectical Thinking, and Collectivistic Coping
The purpose of this study was to understand the relationships among East Asian international students cultural construals of stress (i.e., acculturative stress), psychological wellbeing (i.e., interdependence happiness), cognitive appraisal (i.e., dialectical thinking), and coping skills (i.e., collectivistic coping: seeking social support and forbearance) using Chun, Moos, and Cronkite’s (2006) stress and coping model as the theoretical framework. This study was the first attempt to propose a theoretical framework elucidating the possible relationships among these variables through a cultural lens. A total of 313 self-identified East Asian international students participated in the online-based survey. Using a hierarchical regression, the results revealed that acculturative stress demonstrated the largest effect size among all the independent variables in explaining interdependent happiness among East Asian international students. Additionally, seeking social support as East Asian international students’ collectivistic coping style was found to be a positive contributor; whereas, dialectical thinking contributed negatively to interdependent happiness among East Asian international students. Finally, the higher levels of dialectical thinking, the stronger the negative association was between acculturative stress and interdependent happiness among East Asian international students. Limitations of the study and suggestions for future research are presented. Implications for counseling psychology practice with East Asian international students are also discussed
Remarks on Solving Methods of Nonlinear Equations
Abstract: In the field of mechanical engineering, many practical problems can be converted into nonlinear problems, such as the meshing problem of mechanical transmission. So the solution of nonlinear equations has important theoretical research and practical application significance. Whether the traditional Newton iteration method or the intelligent optimization algorithm after the popularization of computers, both them have been greatly enriched and developed through the continuous in-depth research of scholars at home and abroad, and a series of improved algorithms have emerged. This paper mainly reviews the research status of solving nonlinear equations from two aspects of traditional iterative method and intelligent optimization algorithm, systematically reviews the research achievements of domestic and foreign scholars, and puts forward prospects for future research directions
Object Discovery From a Single Unlabeled Image by Mining Frequent Itemset With Multi-scale Features
TThe goal of our work is to discover dominant objects in a very general
setting where only a single unlabeled image is given. This is far more
challenge than typical co-localization or weakly-supervised localization tasks.
To tackle this problem, we propose a simple but effective pattern mining-based
method, called Object Location Mining (OLM), which exploits the advantages of
data mining and feature representation of pre-trained convolutional neural
networks (CNNs). Specifically, we first convert the feature maps from a
pre-trained CNN model into a set of transactions, and then discovers frequent
patterns from transaction database through pattern mining techniques. We
observe that those discovered patterns, i.e., co-occurrence highlighted
regions, typically hold appearance and spatial consistency. Motivated by this
observation, we can easily discover and localize possible objects by merging
relevant meaningful patterns. Extensive experiments on a variety of benchmarks
demonstrate that OLM achieves competitive localization performance compared
with the state-of-the-art methods. We also evaluate our approach compared with
unsupervised saliency detection methods and achieves competitive results on
seven benchmark datasets. Moreover, we conduct experiments on fine-grained
classification to show that our proposed method can locate the entire object
and parts accurately, which can benefit to improving the classification results
significantly

Characterization of Laser-Resistant Port Wine Stain Blood Vessels Using In Vivo Reflectance Confocal Microscopy.
Background and objectivesPort wine stain (PWS) is a congenital vascular malformation of the human skin. Laser is the treatment of choice for PWS. Laser-resistant PWS is one crucial factor accounting for inadequate treatment outcome, which needs to be fully characterized. This study aims to quantitatively characterize the morphology of laser-resistant PWS blood vessels in the upper papillary dermis using in vivo reflectance confocal microscopy (RCM).Study design/materials and methodsA total of 42 PWS subjects receiving laser treatment from August 2016 through July 2018 were enrolled into this study. Thirty-three subjects had facial PWS; nine had extremity PWS. All subject's PWS received multiplex 585/1,064 nm laser treatment. RCM images were taken before and after treatment. The density, diameter, blood flow, and depth of PWS blood vessels were analyzed.ResultsWe found 44.4% PWS on the extremities (four out of nine subjects) were laser-resistant, which was significantly higher (P < 0.001) when compared with those PWS on the face (15.2%, 5 out of 33 subjects). The laser-resistant facial PWS blood vessels had significantly higher blood flow (1.35 ± 0.26 U vs. 0.89 ± 0.22 U, P < 0.001), larger blood vessel diameters (109.60 ± 18.24 µm vs. 84.36 ± 24.04 µm, P = 0.033) and were located deeper in the skin (106.01 ± 13.87 µm vs. 87.82 ± 12.57 µm, P < 0.001) in the skin when compared with laser-responsive PWS on the face. The average PWS blood vessel density (17.01 ± 4.63/mm2 vs. 16.61 ± 4.44/mm2 , P = 0.857) was not correlated to the laser resistance.ConclusionsLaser-resistant PWS blood vessels had significantly higher blood flow, larger diameters, and were located deeper in the skin. RCM can be a valuable tool for a prognostic evaluation on laser-resistant lesions before treatment, thereby providing guidance for tailored laser treatment protocols, which may improve the therapeutic outcome. The limitations for this study include relative small sample size and acquisitions of different blood vessels before and after 2 months of treatment. Lasers Surg. Med. © 2019 Wiley Periodicals, Inc
