Authors: Geng Feng , Jiang Feng , Conrad Rachel , Liu Tingfang , Liu Yuanli , Liu Huanzhong , Tang Yi-lang 
Published: December 2020

Objective: This nationally representative sample investigates demographic, diagnostic and clinical features associated with both voluntary and involuntary psychiatric hospitalization among children and adolescents psychiatrically hospitalized in China.Method: As part of an official national survey, 41 provincial tertiary psychiatric hospitals in China were selected. Data from 196 children and adolescents who were discharged from these psychiatric hospitals from March 19 to 31, 2019 were retrieved and analyzed.Results: 1. Psychotic symptoms, depressive symptoms and self-injury/suicide were the most common reasons of admission. Girls were significantly likely to be admitted due to depressive symptoms, whereas boys were more likely to be admitted due to aggressive behaviors. 2. The overall rate of involuntary admission was 32.1% (N = 63). Compared to patients who were admitted voluntarily, those who were admitted involuntarily had lower GAF scores on admission, were older, were more likely to present with psychotic symptoms, manic symptoms or aggressive behavior as primary reason for admission, were less likely to present with depressive symptoms, had a significantly longer length of stay, were more likely to be diagnosed with schizophrenia and were less likely to be diagnosed as depressive disorder. 3. A logistic regression showed that depressive symptom as primary reason for admission was significantly associated with voluntary admission (OR = 0.159, p &lt; 0.001), along with two other factors: age (p &lt; 0.01) and a lower GAF score at admission (p &lt; 0.001) were significantly associated with involuntary admission.Conclusion: The rate of involuntary psychiatric hospitalization among children and adolescents is higher in China than in other regions. Developing more specific and more operational criteria to guide involuntary psychiatric admission for child and adolescent patients is of urgency and great importance to ensure appropriate treatment of these patients and protect their rights.

Published: December 2020

Introduction: Relative age effects (RAEs) refer to the overrepresentation of players born earlier in the selection year compared to late-born players within the same age category. To date, the origins and mechanisms of RAEs are still unclear. To evaluate the development of RAEs in terms of age group and selection level, we analyzed data of all registered child and adolescent football players in Switzerland.Methods: Age category, selection level, and birthdate from all licensed 101,991 Swiss child and youth football players assigned to a specific team [9,149 girls (9.0%) and 92,842 boys (91.0%); age range: 4.6–19.6 years] were analyzed. Additionally, out of 1,128 clubs, 54 clubs provided their documented waiting lists (1,224 players). Birthdate distributions were split by age category, sex, and birth quarter (Q1 = January to March, Q4 = October to December). RAEs were calculated using odds ratios (Q1 vs. Q4) with 95% confidence intervals (95% CI).Results: We found small RAEs among U8 players (OR 1.44 [95% CI 1.31, 1.59]) and U10 (OR 1.24 [95% CI 1.16, 1.32]). The RAE was negligible in all other age categories, independent of gender. In children's football, 5,584 (71.3%) teams performed selections. In teams without selection, there were no obvious RAEs. However, teams with selections for the same age category showed small RAEs with an overrepresentation of Q1 athletes in the first team (OR = 1.29 [95% CI 1.24, 1.35]) and inverse RAEs with an underrepresentation of Q1 athletes in the last team (OR = 0.85 [95% CI 0.82, 0.89]). Only small RAEs were observed on the waiting lists for the U8 (OR = 1.48 [1.13, 1.95]).Discussion and Conclusion: RAEs have a small, but consistent effect on participation in Swiss children's football at the grassroots level. Contrary to expectations, no inverse RAEs were found on the waiting lists. Nonetheless, first time coach selections seem to be the origin of RAEs. To protect young athletes from discrimination, RAE biases should be analyzed and eliminated at all stages of sport participation, selection, and dropout situations. Modifications to the organizational structure of sport and athlete development systems are recommended to prevent RAE-related discrimination in youth sports.

Accurate and quantitative assessment of the impact of natural environmental changes and human activities on total suspended solids (TSS) concentration is one of the important components of water environment protection. Due to the limits of traditional cross-sectional point monitoring, a novel water quality evaluation method based on the Markov model and remote sensing retrieval is proposed to realize the innovation of large-scale spatial monitoring across administrative boundaries. Additionally, to explore the spatiotemporal characteristics and driving factors of TSS, a new three-band remote sensing model of TSS was built by regression analysis for the inland reservoir using the synchronous field spectral data, water quality samples and remote sensing data in the trans-provincial Hedi Reservoir in the Guangdong and Guangxi Provinces of South China. The results show that: (1) The three-band model based on the OLI sensor explained about 82% of the TSS concentration variation (R2=0.81, N=34, p value<0.01) with an acceptable validation accuracy (RMSE=6.24 mg/L,MRE=18.02%, N=15), which is basically the first model of its kind available in South China. (2) The TSS concentration has spatial distribution characteristics of high upstream and low downstream, where the average TSS at 31.54 mg/L in the upstream are 2.5 times those of the downstream (12.55 mg/L). (3) Different seasons and rainfall are important factors affecting the TSS in the upstream cross-border area, the TSS in the dry season are higher with average TSS of 33.66 mg/L and TSS are negatively correlated with rainfall from upstream mankind activity. Generally, TSS are higher in rainy seasons than those in dry seasons. However, the result shows that TSS are negatively correlated with rainfall, which means human activities have higher impacts on water quality than climate change. (4) The Markov dynamic evaluation results show that the water quality improvement in the upstream Shijiao Town is the most obvious, especially in 2018, the improvement in the water quality level crossed three levels and the TSS were the lowest. This study provided a technical method for remote sensing dynamic monitoring of water quality in a large reservoir, which is of great significance for remediation of the water environment and the effective evaluation of the river and lake chief system in China.

O objetivo deste artigo é compreender como são construídas, por meio de discursos de autorrepresentação, as identidades dos usuários do aplicativo de relacionamentos Grindr, utilizado principalmente por homens gays (ou bissexuais), com a finalidade de marcar encontros. Busco, especificamente, analisar as representações (homos)sexuais que esses sujeitos fazem de si mesmos e do outro em seus perfis virtuais, averiguando o confronto entre a escolha de certas identidades e o silenciamento de outras através das estratégias de negociações identitárias. A escolha desse aplicativo se deu em razão ao seu intenso crescimento de usuários e pela expressiva popularidade que ele adquiriu nos últimos anos, visto que os sujeitos, caso queiram, podem disponibilizar fotografias e informações básicas sobre si para criarem um tipo de “autoidentidade”. O percurso metodológico utilizado para a análise dos dados busca romper com as fronteiras e limites disciplinares, em direção a uma perspectiva inter/trans/indisciplinar. Amparo-me, para isso, nas perspectivas epistemológicas dos Estudos da Linguagem e da Teoria Crítica do Discurso, dos Estudos Culturais, da Antropologia e da Sociologia.

Published: December 2020

The aim of this study is to determine the effect of ethical leadership behavior on counterproductive behaviors. Data were obtained using the survey technique. The sample of the study consists of 252 employees who work in four - and five - star hotels in Istanbul. According to the results of the analysis, it is found that the "abuse" dimension is the most powerful dimension in order to explain counterproductive work behavior. Counterproductive business behavior is negatively affected by ethical leadership behaviors. In addition, ethical leadership has a negative impact on behaviors related to abuse, withdrawal, theft, sabotage, and deviation from production and service, which have counterproductive business behavior dimensions.

Published: December 2020

Present world is crippled with pandemic COVID-19 that has caused innumerable economic damages and claimed lakhs of lives of people worldwide. There is so much fear among masses, economic activities are shut down, preventive measures are being taken worldwide. World has witnessed many epidemics and pandemics in the past too but it is first time in the history that economies are in complete “lockdown” world over. The lockdown or closure of economies is causing innumerable economic damages worldwide. The present paper aims at to analyse the impact of COVID-19 on total Indian economy in general and rural economy of India in particular, its impact on daily wage earners and migrant workers. In addition to this, the paper also makes an attempt to analyse the impact of COVID-19 on travel & tourism study in India as well as across the globe. The major conclusion drawn from the study is that the Indian economy is going through its one of the worst times and this has put migrant workers in an uncertain situation. Tourism, hotel industry, transport, manufacturing, agriculture etc. sectors are witnessing massive economic damage. The tourism industry is worst affected in India as well as across the globe due to the outbreak of COVID-19 pandemic and around 100 million direct tourism jobs are at risk. The growth rate of GDP in India is expected to contract to around 2% in financial year 2020-21. This indeed will be a big cause for worry and drastic economic efforts will be needed from all the quarters to restore balance to Indian economy.

Abstract
Ultra-small red micro-LEDs (<10 μm) with measurable output power have proved difficult to demonstrate. The smallest state-of-the-art red micro-LEDs (AlInGaP) to have exhibited a decent output power of ∼1.75 mW mm−2 are 20 μm × 20 μm in dimension. InGaN-based red micro-LED development has primarily been impeded due to the large lattice mismatch between the substrate and the quantum wells along with fabrication challenges such as low damage etching. In this work, we demonstrate 6 μm × 6 μm sized InGaN red micro-LEDs with an on-wafer external quantum efficiency of 0.2% and light output power reaching 2.1 mW mm−2.

Published: December 2020

Due to their excellent biocompatibility, titanium alloys are tremendously as implants used, since relatively low modulus, corrosion resistance, and good fatigue strength. The biocompatibility, comes from the formation of natural Titanium dioxide (TiO2) layer. Therefore, TiO2 layer growth surface alteration is frequently applied to improve biological, chemical , and mechanical properties. TiO2 nanostructures are obtained under self-organization conditions by electrochemical anodization of Ti-6Al-4V. Parameters of anodization such as anodization time, voltage and addition of thiourea were evaluated in the composition of the H3PO4+NH4F solution. The morphology and elements of the Ti alloys surface were analyzed by Scanning Electron Microscopy (SEM) and Energy-Dispersive Spectroscopy (EDS), whereas potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) were used to evaluate the TiO2 layer in corrosion resistance. The results showed that the anodized Ti-6Al-4V alloy E-corr imcreased as the anodization voltage increased. Titanium alloy anodized using 12 V during 2 hours with H3PO4 + NH4F without thiourea solution had the thickest of oxide layer and highest corrosion resistance. Higher applied voltages have been shown to increase the deposition rate and coating thickness. Addition of thiourea has a definite effect on the inhibition of oxide layer of titanium. In order to produce the optimum titanium surface, the required applied anodization voltage and addition of volume thiourea is necessary.
