Sensitivity Experiments on the Role of Water Vapor in the Eastward Propagation of MJO

In this study, we employed the nudging assimilation of the Weather Research and Forecasting (WRF) model to conduct a set of sensitivity experiments on the role of water vapor in the Madden-Julian Oscillation (MJO) eastward propagation, focusing on the eastward propagating 30-60d low-frequency component in the tropical atmosphere from the Indian Ocean to the western Pacific Ocean during September-November 2004. Using 11 different cumulus parameterization schemes, the simulation results show that the ability of the regional climate model in simulating the MJO eastward propagation is sensitive to the cumulus scheme: A suitable scheme can well reproduce the MJO eastward propagation characteristics, while most schemes show no skill for the MJO eastward propagation. When the water vapor in the model domain was assimilated using reanalysis data with nudging technique, we found that the low-frequency evolution of the tropical zonal wind exhibits MJO features well, and the low-frequency phase of water vapor is ahead of the zonal wind by about 6-7 days, which suggests that the atmospheric water-vapor distribution is the key factor for the eastward propagation of the MJO, and the effect of water-vapor field via affecting the atmospheric stability. When the atmospheric temperature assimilation was conducted, there was almost no improvement in the skill of MJO simulation.
Microlearning in the Higher Education Hospitality Classroom

ABSTRACT Due to ever-changing student engagement and shifting industry demands the classroom environment is being impacted. Though quality has always been at the heart of the university’s education mission, staying relevant with teaching methods that keep student’s attention yet convey substance is critical. The purpose of the current study was to explore the effectiveness of using microlearning in hospitality classrooms in higher education. Five microlearning modules were developed and tested in various hospitality courses. Results showed an increase in student’s self-reported knowledge after the microlearning module. Students agreed that microlearning helped them develop reasoning skills, was an interesting way to learn, as well as assisted them in understanding the content. Furthermore, students agreed they would like to see more microlearning modules in other classes.
Container Throughput Forecasting of Tianjin-Hebei Port Group Based on Grey Combination Model

Container throughput forecasting plays an important role in port capacity planning and management. Regarding the issue of container throughput of Tianjin-Hebei Port Group, considering the container throughput is an incomplete grey information system affected by various factors, the effect is often unsatisfactory by adopting a single forecasting model. Therefore, this paper studies the issue by combining fractional GM (1, 1) and BP neural network. The comparison results show that the combination model performs better than other single models separately and has a higher level of forecasting accuracy. Furthermore, the combination model is adopted to forecast the container throughput of Tianjin-Hebei Port Group from 2021 to 2025, which would be a data reference for the future development optimization for the container operation of Tianjin-Hebei Port Group.
Residual compressive strength of plain and fiber reinforced concrete after exposure to different heating and cooling regimes

Abstract The article investigated the impact of different cooling regimes on the response of both plain and fibre reinforced concrete (FRC) after heating. A total of 256 standard concrete cylinders of normal strength concrete (NSC) and high strength concrete (HSC) were tested in compression after heating at 200 °C, 400 °C, and 600 °C. For each concrete grade, 32 specimens were prepared without fibres while 96 cylinders had fibres (steel, polypropylene (PP) and their hybrid) in the concrete mixture. The cooling regimes adopted for cooling the test specimens were water quenching and natural ambient cooling. Effect of studied parameters was evaluated for tested cylinders in terms of stress-strain characteristics, residual strength, modulus of elasticity, and failure modes. For both NSC and HSC, the reduction in strength increased significantly when the temperature was increased from 400 to 600 °C. At 600 °C, the use of steel fibres caused lower loss in compressive strength, elastic modulus and energy absorption as compared to the use of PP and hybrid fibres. The residual strength of water quenched concrete was more than the air cooled concrete because the heated specimens were kept submerged in water for 24 h, which helped in the rehydration of anhydrous cement products.
Examining the role of passion in university students’ academic emotions, self-regulated learning and well-being

University students’ passion for their studies has been previously demonstrated to be important for both their academic performance and their personal well-being. However, no studies to date have explored the role of passion for one’s studies on both academic and personal outcomes in a single model. The present research sought to determine the role of passion in adult university students’ self-regulated learning and psychological well-being (Study 1), as well as the process by which passion shapes these outcomes, namely academic emotions, in Study 2. It was hypothesised that harmonious passion would positively predict both self-regulated learning and psychological well-being in Study 1. Furthermore, the mediating role of academic emotions between passion and outcomes was tested using a prospective design over time in Study 2. Results provided support for the proposed model. Implications for future research and practice focusing on the role of passion in facilitating adaptive emotions, use of self-regulation and well-being in adult students are discussed.
Have you considered the opposite? A debiasing strategy for judgment in criminal investigation

Fundamental challenges in human decision-making pose a serious threat to fair evidence evaluation, verdicts in court proceedings, and the administration of justice. Drawing on cognitive psychology, we examined whether a consider-the-opposite approach can assist police officers with positive guidance on how to implement crucial legal thresholds such as the presumption of innocence. In an experiment with sworn police officers (N = 100), we compared a consider-the-opposite condition and a control condition (with no further instructions) and measured the formulated alternative hypotheses. The results show a promising debiasing effect of the consider-the-opposite approach which may strengthen fundamental principles of criminal law.
Impact of COVID-19 on different business models of European airlines

ABSTRACT In addition to social damage, the first wave of the COVID-19 pandemic also caused huge economic losses in the beginning of 2020, especially for companies in the tourism sector. The airline market was no exception. This study examines the significance of the business model of European listed airlines – low cost carriers (LCCs), full service carriers (FSCs) – for stock market performance. We use event study on the 11 airlines included in the sample. In terms of cumulative average abnormal returns, i.e. the most significant deviations from expected returns, negative phases can be detected in the entire and third stage of the pandemic. FSCs performed significantly better than LCCs at the time of the pandemic on 24 February, when European stock markets suffered the most damage; the business model overwrote financial indicators during the toughest period of the crisis. Although most LCCs had higher cash/assets ratios, they still produced worse results than the average performance of companies with lower cash/assets ratios. This analysis helps to ensure that, in addition to examining financial indicators, the enumeration of the business model in this industry can also be decisive. The future possibilities of the research are discussed at the end of the study.
Clinical and paraclinical predictive factors for in-hospital mortality in adult patients with COVID-19

Background Since December 2019, a type of coronavirus has emerged in Wuhan, China, which has become the focus of global attention due to an epidemic of pneumonia of unknown cause, called COVID-19. This study aimed to investigate the factors affecting in-hospital mortality of patients with COVID-19 hospitalized in one of the main hospital in central Iran. Methods This retrospective cross-sectional study (February 2019-May 2020) was conducted on patients with confirmed diagnosis COVID-19, who were admitted in Yazd Shahid Sadoughi Hospital, in middle of Iran. The patients with uncompleted or missed medical files were excluded from the study. Data were extracted from the patients' medical files and then analyzed. The patients were categorized as survivors and non-survivors groups, and they were compared. Results Totally, 573 patients were enrolled, that 356 (62.2%) were male. The mean ± SD of age was 56.29 ± 17.53 years, and 93 (16.23%) were died. All the complications were more in non-survivors. Intensive care unit (ICU) admission was in 20.5% of the patients which was more in non-survivors (P < 0.001). The results of multivariate logistic regression test showed that plural effusion in lung computed tomography (CT) scan (OR = 0.055, P = 0.009), white blood cell (WBC) (OR = 1.417, P = 0.022), serum albumin (OR = 0.009, P < 0.001), non-invasive mechanical ventilation (OR = 34.315, P < 0.001), and acute respiratory distress syndrome (ARDS) (OR = 66.039, P = 0.001) were achieved as the predictive factors for in-hospital mortality were the predictive factors for in-hospital mortality. Conclusion In-hospital mortality in patients with COVID-19 was about 16%. Plural effusion in lung CT scan, WBC, albumin, non-invasive mechanical ventilation, and ARDS were obtained as the predictive factors for in-hospital mortality.
Facilitating EFL students’ civic participation through digital multimodal composing

ABSTRACT Although there is a growing call for L2/EFL teachers to connect the words they teach in classrooms with the world students participate outside classrooms, opportunities for L2/EFL students to engage with civic participation (CP) in language curricula remains limited. Drawing on student-authored videos from a digital multimodal composing (DMC) programme in China, this study reports on students’ manifestation of CP during DMC. Data from student-authored videos, classroom observation, and interviews reveal that the students used DMC for three forms of CP, including advocacy of the sexually discriminated, fundraising efforts for the left-behind children stricken by poverty, and promoting civic learning of disease-related knowledge and protection measures. The findings also reveal that these forms of CP were manifested by the students’ creative remixing of videos and visuals and ingenious layering of student-generated narrations based on their authentic concerns and community experiences. Implications on how DMC can be used to facilitate students’ CP in language curricula are discussed.
Etude des compartiments d’hydrolyse et de méthanogenèse d’un procédé de méthanisation en voie épaisse multi-étapes phasé en température : Le procédé Arkométha

Le procede Arkometha® est un systeme de digestion anaerobie de rejets organiques fonctionnant en voie epaisse et comprenant plusieurs compartiments phases en temperature. Ce travail s’est interesse aux performances des differentes phases du procede pour le traitement de residus agricoles. Dans un premier temps, le compartiment d’hydrolyse a ete etudie. Les parametres les plus influents ont ete identifies (temperature et duree de l’hydrolyse) a l’aide d’un plan d’experience. Ils ont ensuite ete testes sur un pilote afin d’evaluer leur influence sur la solubilisation et la production de methane ulterieure. Des tests ont alors ete conduits a l’echelle laboratoire en mode continu au moyen de reacteurs en series. Le compartiment methanogene, constitue de deux a trois secteurs, a ete etudie en mettant en evidence l’efficacite de chaque secteur. L’effet de la temperature a ici egalement ete etudie, avec un impact important. Les deux compartiments ont ete mis en serie permettant l’etude du procede complet. Ceci a permis de mettre en lumiere certains risques lies a des combinaisons de temperature peu favorables. Par ailleurs, une comparaison avec un procede mono-etape a ete effectuee. Outre l’etude des performances de chaque compartiment et l’analyse de leur articulation, un resultat interessant de ce travail reside dans l’affinement de la notion d’hydrolyse dans le cadre de la methanisation en voie epaisse, communement confondue avec la solubilisation. En effet, nous avons montre que le gain apporte par l’utilisation d’un reacteur sequence avec un compartiment dedie a l’hydrolyse ne reside pas dans l’amelioration de la solubilisation, mais dans l’augmentation consequente de la cinetique de methanisation dans les etapes suivantes. De facon interessante, alors que la temperature joue un role primordial dans la solubilisation de la matiere organique, elle est relativement peu influente pour l’amelioration de la cinetique de degradation, ou le temps de sejour devient preponderant.
Part of the Problem? The Eurasian Economic Union and Environmental Challenges in the Former Soviet Union

ABSTRACT While there is a sizable body of evidence linking greater economic freedom to better environmental outcomes, there is an ambiguous relationship of trade to the environment. What occurs when trade expands among countries that already have shown that the environment is not a priority? Such an example comes from real life with the Eurasian Economic Union (EaEU), a collection of autocracies that have pursued integration but without any extensive, market-based liberalization. This paper examines the role of the EaEU in increasing trade among its member states and shows that the EaEU did indeed lead to more environmentally unfriendly production.

PD‐L1 expression is low in large B‐cell lymphoma with MYC or double‐hit translocation

In large B‐cell lymphoma (LBCL), MYC translocation and MYC/BCL2 or MYC/BCL6 double hit (DH) are associated with poor prognosis, and there is an unmet need for novel treatment targets in this patient group. Treatments targeting the PD‐L1/PD‐1 pathway are still poorly elucidated in LBCL. PD‐L1 expression might predict response to treatment targeting the PD‐L1/PD‐1 pathway. We therefore investigated the relationship between PD‐L1 protein and mRNA expression levels and MYC and DH translocation in LBCL. We detected MYC, BCL2, and BCL6 translocation by fluorescent in situ hybridization in tissue samples from 130 patients randomly selected from two cohorts of patients with LBCL: 49 patients with MYC translocation of whom 36 had DH and 81 without MYC translocation. PD‐L1 protein expression was detected by immunohistochemistry (IHC) in tissue samples from 77 patients and PD‐L1 mRNA expression by next‐generation RNA sequencing (NGS) in another 77 patients. Twenty‐four patients overlapped, ie, were analysed with both IHC and NGS. Nonparametric tests were performed to evaluate intergroup differences. PD‐L1 protein expression level was significantly lower in patients with MYC (n = 42, median = 3.3%, interquartile range [IQR] 0.0‐10.8) or DH translocations (n = 31, median = 3.3%, IQR 0.0‐10.0) compared with patients with no MYC (n = 35, median = 16.7%, IQR 3.3‐30.0) or no DH translocations (n = 46, 13.3%, IQR 2.5‐30.0), P = . 004 and P ≤ . 001, respectively. PD‐L1 mRNA expression was also significantly lower in patients with MYC or DH translocations, P = . 001 and P = . 006, respectively. Higher PD‐L1 protein and mRNA expression levels were associated with non–germinal centre (GC) type compared with germinal centre B‐cell (GCB)‐type diffuse LBCL (DLBCL), P = . 004 and P = . 002, respectively. In conclusion, we report an association between low PD‐L1 expression and MYC and DH translocation in patients with LBCL. Our findings may indicate that patients with MYC or DH translocation may benefit less from treatment with PD‐L1/PD‐1‐inhibitors compared with patients without these translocations. This should be evaluated in larger, prospective, consecutive trials.
Possible heterogeneous chemistry of hydroxymethanesulfonate (HMS) in northern China winter haze

Abstract. The chemical mechanisms responsible for rapid sulfate production, an important driver of winter haze formation in northern China, remain unclear. Here, we propose a potentially important heterogeneous hydroxymethanesulfonate (HMS) chemical mechanism. Through analyzing field measurements with aerosol mass spectrometry, we show evidence for a possible significant existence in haze aerosols of organosulfur primarily as HMS, misidentified as sulfate in previous observations. We estimate that HMS can account for up to about one-third of the sulfate concentrations unexplained by current air quality models. Heterogeneous production of HMS by SO2 and formaldehyde is favored under northern China winter haze conditions due to high aerosol water content, moderately acidic pH values, high gaseous precursor levels, and low temperature. These analyses identify an unappreciated importance of formaldehyde in secondary aerosol formation and call for more research on sources and on the chemistry of formaldehyde in northern China winter.
Flipped Classroom in the Context of Higher Education: Learning, Satisfaction and Interaction

Educational governmental institutions have recommended implementing blended learning in higher education to respond to the “new educational normality” caused by the COVID-19 pandemic, although this is not a new challenge. Over the last few decades, higher education institutions have tried to incorporate the use of technological devices to university teaching, by redesigning and optimizing the learning experiences through a mixed teaching model. In this context, the Flipped Classroom (FC) model is one of the pedagogical models that is revolutionizing the scope of education. However, there is still not enough evidence of its advantages and disadvantages in the university stage. Therefore, it is important to analyze the impact of the FC on the learning, satisfaction and interaction of the different agents of the university community. Due to the idiosyncrasy of the present study, an exclusively qualitative and longitudinal methodology was selected; thus, 266 interviews based on open questions were conducted throughout the last five years. The results show that students value the FC model positively and corroborate its great potential from academic, competence, personal and social perspectives. Nevertheless, a small group of students are still very critical about the model and would prefer to keep using a traditional methodology, mainly due to the lack of habit using active methodologies and establishing the learning commitment required by such methodologies.
The general and facet-specific job satisfaction of voluntary referees based on the model of effort-reward imbalance

ABSTRACT Research question Despite the importance of referees for competitive sports and their decreasing numbers in various countries across sports leading to organisational problems, little is known about their job satisfaction and its determinants, although it substantially contributes to their intention to continue. To overcome this research gap, this study examines voluntary referees’ general job satisfaction and several job satisfaction facets, their efforts and rewards based on the effort-reward imbalance (ERI) model and how this ERI relates to their job satisfaction. Research methods The study’s sample consists of n = 3075 voluntary football referees in Germany having completed the online survey. Logistic regression analyses, confirmatory factor analysis and structural equation modelling were employed to answer the research questions. Results and Findings The four job satisfaction facets esteem, colleagues, promotion prospects and expense allowance all significantly predict the voluntary referees’ general job satisfaction accounting for more than one-third of its variance. While esteem shows the highest practical relevance in determining job satisfaction, promotion prospects and expense allowance have the lowest influence. Although voluntary referees predominantly do not indicate an ERI, it is significantly associated with job dissatisfaction. Implications This study enriches theory considering general and facet-specific job satisfaction in combination with the ERI model. Practically, to create a satisfying refereeing environment, associations should particularly ensure that referees feel appreciated for their voluntary activity and foster the social interaction among referee colleagues strengthening their camaraderie. Furthermore, associations can attempt to reduce efforts or increase rewards to prevent referees’ job dissatisfaction.
Influence of poly(lactide) stereocomplexes as nucleating agents on the crystallization behavior of poly(lactide)s

The influence of the addition of linear and four-arm poly(lactide) (PLA) stereocomplexes (scPLAs) on the non-isothermal and isothermal crystallization behavior of poly(l-lactide) (PLLA) and poly(d-lactide) (PDLA) from the molten state was investigated. The linear PLAs and four-arm PLA with a similar chain length for each arm were synthesized by ring-opening polymerization. The linear and four-arm scPLAs were then prepared by solution blending and characterized by 1H-NMR, FTIR, and WAXD analysis. Various mass ratios of the scPLAs were subsequently added to PLLA and PDLA as nucleating agents and specimens were prepared by solution casting. The isothermal and non-isothermal crystallization behavior of the specimens was examined by differential scanning calorimetry and polarized optical microscopy. The SC crystallites effectively promoted the nucleation of the PLAs, thereby increasing the general crystallization rate of the matrix. A 10% content of stereocomplex nucleating agent increased the crystallization rate of PDLA and PLLA by more than 55% and 70%, respectively. Compared with the linear scPLA, the four-arm scPLA more strongly promoted crystallization at higher temperatures. This might be because the greater degree of branching and larger steric hindrance of the four-arm scPLA led to the formation of defective SC crystallites, which was more beneficial for adsorption of the matrix on the crystal surface and permitted the nucleation and growth at higher temperatures. These results demonstrate that scPLAs can potentially be used as nucleating agents to improve the performance and transparency of PLA films.
