Predictive Parameters for the Worsening Clinical Course of Mild COVID-19 Pneumonia

Background: This study aimed to determine parameters for worsening oxygenation in mild COVID-19 pneumonia.Methods: This retrospective cohort study included confirmed COVID-19 pneumonia in a single public hospital in South Korea from January to April 2020. Parameters were compared between the two groups on the basis of clinical course: the desaturation group was defined as those with oxygen saturation ≤ 94% on ambient air, or received oxygen or mechanical ventilation (MV) throughout the clinical course versus the nonevent group who were without any respiratory event up to 28 days. The severity and extent of viral pneumonia from an initial single chest CT were calculated using artificial intelligence (AI) algorithms and measured visually by a radiologist. Results: We included 136 patients with 32 (23.5%) in the desaturation group, of whom two needed MV and one died. Initial vital signs and duration of symptoms showed no difference between the two groups, however, univariate logistic regression analysis revealed that a variety of parameters at admission were associated with an increased risk of a desaturation event. In a sex-, age-, and comorbid illness-matched case-control study, ferritin ≥ 280 μg/L (OR 3.600, 95% CI 1.142-11.346; p=0.029), LDH≥ 240 U/L (OR 3.600, 95% CI 1.142-11.346; p=0.029), pneumonia burden (OR 1.010, 95% CI 1.002-1.019; p=0.021), and extent (OR 1.194, 95% CI 1.017-1.401; p=0.030) by AI, and visual severity scores (OR 1.146, 95% CI 1.005-1.307; p=0.042) were the predictive parameters for worsening clinical course with desaturation. Conclusion: Our study presents initial CT parameters measured by AI or visual severity scoring as well as serum markers of inflammation at admission as the best parameters for predicting worsening oxygenation in the COVID-19 pneumonia cohort. Initial chest CT scans may help clinicians diagnose viral pneumonia and evaluate the prognosis in mild COVID-19.
Surface Structures of Black Phosphorus Investigated with Scanning Tunneling Microscopy

The atomic and electronic structures of the black phosphorus surface are investigated by means of scanning tunneling microscopy (STM) combined with density functional theory (DFT) calculations for the first time. STM measurements reveal that the atoms on the surface occupy almost the same sites that they would have in bulk, except for a little relaxation perpendicular to the surface, which causes the atoms to take two types of positions (P1 and P2) with a contrast visible in the STM images. DFT calculations indicate that the small difference in height of 0.02 A between atoms at P1 and P2 position breaks the symmetry, leading to an apparent discrimination of electronic structures. The bias-dependent variation of the contrast between P1 and P2 in the STM images is consistent with the DFT simulations.
Regulation, Compensation and Risk Taking in Banks: Evidence from the Credit Crises

We study regulation, executive incentives and risk taking in banks during the recent credit crises. Using a hand-collected dataset covering 352 banks from 15 countries we find that regulation effectively reduces bank risk as measured by commonly used measures of bank risk. However, bank performance during the recent credit crises is negatively correlated with the level of bank regulation. A more detailed analysis reveals, that incentives of bank executives are more pronounced in countries with stricter bank regulation. This is consistent with the view that shareholders aim to jeopardize the effect of regulation by providing stronger incentives. Also consistent with that view, the level of incentives positively affects the level of bank risk and examining bank performance during the recent credit crises this effect becomes stronger as bank regulation becomes stricter. Overall, the findings suggest that regulatory initiatives should carefully consider their (unintended) consequences for incentive structures within banks.

Adolescents ’ intentions of risky driving : the importance of psychosocial factors in Lithuanian sample

Background, purpose. The great variety of behaviors and social or personal characteristics can contribute to high crash rates among adolescents. Besides adolescents’ risky driving is possibly related to later risky driving behaviors in adulthood. Here is assumed that risky driving intentions in adolescence tend to lead to actual risky driving behavior. So this study aimed to examine the relations between psychosocial factors and intentions of risky driving in adolescence, also to explore the replication of previous findings in correlates of adolescent risky driving intentions in Lithuanian sample. Methods. A self-report questionnaire survey was distributed to 222 Lithuanian adolescents. Results. The results showed that the level of risky driving intention was significantly higher for males than females. Adolescents, who had more problematic friends, were more oriented to material values, demonstrated higher levels of intentions to risky driving. Parental restrictions, some values and psychosocial function of driving did not emerge as predictors. Conclusions. It is concluded that psychosocial factors taken in a complex manner might be important in the explanation of adolescents’ risky driving intentions. Lithuanian adolescents reflect similar psychosocial factors related to risky driving behavior as in other countries.
Institutions of the Academy of Sciences as Centers for Science Popularization in Russia

Scientific knowledge is increasingly needed in more and more areas of life. Various industries, economics, and even politics cannot be truly effective without close interaction with science. This is especially important for planning and making long-term decisions. A person who lacks basic scientific knowledge cannot be involved in modern industries, but also loses the chance to make reasonable chooses. Instead, he is extremely vulnerable to manipulations and thus cannot consciously influence his own life and the life of future generations. World level of scientific education remains extremely low, including developed countries. The modern society realizes this problem and there is a great demand on improving common scientific education and accessibility of reliable scientific information. However, the popularization of sciences not very effective today for a number of reasons. Using the Russian Academy of Science as an example, current article discusses these reasons with a special emphasis on the problems arising in the transmission of scientific knowledge. Then, the paper proposes a number of detailed algorithms for the popularization of science and raising the level of scientific education in society.
Game-Based Learning for Competency Abilities in Blended Museum Contexts for Diverse Learners

 Museums offer a lifelong edutainment environment with flexible choices for the public and provide fruitful interdisciplinary learning resources to support competency-based education. However, the lack of proper scaffolding and supports in museums negatively affect learner learning. Further, the individual differences need to be considered to effectively support the diverse learners learning in museums. In this study, an innovative learning model to support competency education for lifelong learning in museums is proposed. A game-based learning service named CoboFun that offers various types of problem-solving activities was developed to facilitate learners’ interaction with exhibits and their peers in the museum. To examine the service design of CoboFun, learners’ perceptions were evaluated and the differences in their cognitive styles were examined (Field Independent (FI) and Field Dependent (FD)). The results showed that both FI and FD learners enjoyed learning with CoboFun but that flexible learning tools needed to be provided to satisfy the different needs for the learners with different cognitive styles.
Raman spectrum of 
CrI3
: An 
abinitio
 study

We study the Raman spectrum of CrI$_3$, a material that exhibits magnetism in a single-layer. We employ first-principles calculations within density functional theory to determine the effects of polarization, strain, and incident angle on the phonon spectra of the 3D bulk and the single-layer 2D structure, for both the high- and low-temperature crystal structures. Our results are in good agreement with existing experimental measurements and serve as a guide for additional investigations to elucidate the physics of this interesting material.

A narrative review on alexithymia in adolescents with previous adverse experiences placed for adoption, in foster care, or institutions. Prevalence, gender differences, and relations with internalizing and externalizing symptoms

Alexithymia is a recognized risk factor for psychopathology, showing relationships with internalizing and externalizing symptoms. The prevalence of alexithymia ranges from 7-21% in low-risk community adolescents, especially girls. Further, few retrospective studies suggest a higher incidence in individuals with past traumatic experiences, but they are mostly on clinical adults. Therefore, the current narrative review aimed to examine the state-of-art of literature on alexithymia (in terms of prevalence, gender differences, and relationships with internalizing-externalizing symptoms), in non-clinical adolescents potentially at “high-risk” for alexithymia because placed for adoption, in foster care or institutions due to adverse and potentially traumatic experiences (parental abandonment, neglect, abuse, etc). The review of the literature was computed on documents retrieved through electronic databases (ProQuest, PsycInfo, PsycArticles, PubMed, WOS, Scopus, Google Scholar), included according to their pertinence and type (empirical studies). Of 6379 documents, only 6 studies (0.2%) on institutionalized adolescents met the inclusion criteria, none in adopted and foster care groups. Main results revealed: 1) higher prevalence of alexithymia in institutionalized adolescents (38-85%) compared to community peers; 2) institutionalized girls as more alexithymic, showing more difficulty in identifying and describing feelings than boys, like in community groups; 3) Higher alexithymia was related to more total, internalizing and externalizing problems through similar mechanisms of risk than in community groups. Methodological limits and future directions of research are discussed for each topic, highlighting the need to bridge the research gap on adolescents with adverse backgrounds, potentially at “high-risk” for alexithymia and its negative consequences.
Patterns of serum CEA levels in different clinico-pathological variables of colorectal cancer

Background: Globally, colorectal malignancy is the 3 most frequent cancer and the 2 major cause of mortality. Serum carcinoembryonic antigen (CEA) is a simple tumor marker for the diagnosis, predicting response to therapy and survival and identifying the recurrence of colorectal cancer. Therefore, the aim was to evaluate the pattern of serum CEA levels in patients with colorectal cancer presenting at a tertiary care hospital in Karachi Patients and methods: It was a cross-sectional study conducted at the Department of Medical Oncology of Jinnah Postgraduate Medical Center, Karachi from January till August 2019. One ninety-nine patients of 12-80 years age and either gender diagnosed with colorectal cancer (biopsy-proven) were included. Data on demographics, clinical and pathological findings were recorded in the pre-designed proforma. The serum CEA levels in colorectal cancer patients were assessed using an ELISA kit. CEA levels higher than 5.0 ng/mL were deemed as elevated CEA levels in colorectal patients. Data were analyzed using SPSS version 23. Results: A total of 191 colorectal cancer patients were included. The mean age of the patients was 42.81±15.22 years. Most of the patients (61.3%) were male. Out of 191 colorectal cancer patients, 60 (31.4%) had CEA level 0-0.3 ng/ml, whereas 79 (41.4%) had elevated serum CEA level (>10 ng/ml). The CEA levels were stratified with respect to effect modifiers. The size of the tumor, TNM staging and localization and metastasis of cancer showed a statistically significant difference between levels of CEA (p<0.05). Conclusion: The raised CEA levels are associated with clinically progressive or presence of residual and recurrent disease. For patients with progressive tumors, particularly colorectal carcinoma, CEA assays are an important guide to assess the burden of the tumor, hence clinicians and surgeons ought to monitor antigen levels. It is recommended to enhance the clinical efficacy of the CEA levels.
Stakeholder Demand for Accounting Quality and Economic Usefulness of Accounting in U.S. Private Firms

For some privately-held firms, the costs of providing high-quality accrual-based financial statements may outweigh the benefits of accommodating the demands of their stakeholders who may rely more on cash flows or have direct access to management. For other private firms, greater stakeholder demand for their financial information necessitates them providing higher-quality accounting. Using a large sample of U.S. private firms, we first confirm that accrual quality in private firms is associated with the ability of accruals to predict future cash flows. Next, we predict and find that accrual quality increases with the demand for monitoring by equity investors, lenders, and suppliers. Overall, our evidence suggests that accrual quality of private U.S. firms is useful, has economic consequences, and varies predictably with certain firm characteristics.
A Primary Study on Oral Vaccination with Liposomes Entrapping Koi Herpesvirus ( KHV ) Antigens Against KHV Infection in Carp

“Koi herpesvirus (KHV)” is an emerging piscine herpesvirus that only infects koi carp Cyprinus carpio koi and common carp C. carpio carpio causing mass mortalities with severe economic losses worldwide since 1998. Therefore, protection of carp with KHV vaccines is urgently needed. We developed an improved liposome-vaccine containing KHV antigens within the liposomal membrane compartment for oral vaccination to carp. Carp immunized by 3 day oral administrations of the liposome-KHV vaccine showed 77% survival against a challenge with 101.3 TCID50 /100 L of KHV while unvaccinated control fish showed 10% survival. The relative percent survival (RPS) was 74%. This demonstrated that oral immunization with the liposome-KHV vaccine was efficacious against KHV infection in carp.

The Cyclical Behaviour of Regional Growth Rates in China

Chinese economic growth has been rapid and sustained over the past two decades but has varied significantly across regions. We analyse economic growth disparities at the provincial level using combined time-series and cross-section data within a framework first used by Thirlwall in 1966 for the analysis of unemployment rate disparities in the UK. We find considerable differences in the sensitivity of provincial growth rates to fluctuations in the national growth rate, with the most sensitive provinces generally having the highest average growth rates. Thus continued increases in the national rate will exacerbate disparities. We find that industrial structure has little explanatory power for sensitivities and experiment with various measures of geography and policy. We find that a simple coastal dummy variable has the greatest explanatory power, eclipsing the policy variable. We use our analysis to predict that an increase in the national growth rate to double-digit levels will considerably worsen the dispersion of growth rates across the provinces.
The role of excitations statistic and nonlinearity in energy harvesting from random impulsive excitations

Design of an efficient energy harvester is now feasible as technology develops and a viable approach to solve this need is to exploit the concept and application of a nonlinear design. In this letter, we conducted a comparative analysis of linear and nonlinear piezoelectric energy harvesting from random impulsive excitations modelled by white Poisson noise. It is shown that the harvester performance depends on both nonlinearity and properties of ambient energy, and nonlinearity should be optimized for a given type of ambient vibration in order to achieve efficient harvesting.
Urban cultural amenities and the migration of the creative class

This paper models the migration of the Creative Class (Florida, 2003) in a New-Economic-Geography framework. Beside wage differentials, urban cultural amenities play an important role on the choice of location. A public cultural good, financed by taxes, is introduced as an agglomeration force. The public-good is purely consumed by skilled workers. Additionally urban cultural diversity across cities is taken into account to model exogenous differences between cities. I analyze the political equilibrium of tax competition. Furthermore the effects of asymmetries of cities and trade liberalization is examined. There is an optimal level of provision of public cultural goods. In the dispersion-scenario the equilibrium tax rate for workers is hump-shaped with respect to trade integration while for skilled workers it is u-shaped. In the core-periphery scenario the equilibrium tax rate for the core decreases with increasing trade freeness.
The Effect of Recognition and Comprehension Test-types on Listening Comprehension at Junior High School

This present study investigated the effectiveness of two specific test-types of recognition and comprehension of EFL learners at junior high school. The method of the study was quasi-experimental with pre and post-test. 90 female students were selected at the National Iranian Drilling Company (NIDC) Junior High- School in Ahvaz participated in this study. They were randomly divided into three equal groups. After conducting a pre-test of listening, the first experimental group received listening tasks of recognition exercises and the second experimental group received listening comprehension exercises in the treatment period. The control group worked on the regular exercises of the listening textbook. Results showed that there was a significant difference between pretest and posttest in the recognition test-type group. However, results revealed no significant difference between the comprehension test-type group and the control group. Recognition test-type enhances the listening comprehension skill of learners and maybe a suitable alternative for traditional methods of teaching listening comprehension. Implications of the study suggest that recognition test-types an exercise may boost learners' recall of listening cues. The novelty of this study might be the use of the backwash effect (Weir, 2005) of testing on teaching listening comprehension among EFL Iranian learners at junior high school.
