Why has Macao attracted the world-record gaming revenue?
Authors: Lam Carlos Siu 
Published: August 2020

Macao, located on the southeast coast of China, is perfectly situated to receive patrons from China about thirty years after its open-door policy in 1978 when they have accumulated significant amounts of wealth. With its gaming liberalization and the supply of such mainland Chinese patrons, Macao has become the world’s gambling capital since 2007. This article aims to analyze the major factors leading to this dominant economic performance.

The experience of the mainland Chinese in the Cultural Revolution and the Era of the Gang of Four has motivated them to get rich quick to enjoy the material comforts that they have been deprived. Given that baccarat has a low house edge and is easy to play, many mainland Chinese like to play baccarat in Macao. Moreover, the interaction with the card afforded by baccarat, makes patrons feel that that they can control over the gambling outcome, and this fits the mainland Chinese psychology in their attempt to win much and quick with their high stakes.

On the other hand, casinos have trained croupiers to make their patrons stay longer, including being polite, identifying the emotional status of patrons, managing patrons’ emotions and regulating the croupiers’ own emotions. In this way, casinos in Macao not only can make patrons experience sovereignty while in control of the staff-client interactions, but also help Macao attract the world-record gaming revenue.
The Link Between Information and the Favorite-longshot Bias in Pari-mutuel Wagering Markets
Authors: Weinbach Andy 
Published: August 2020

This paper examines a database of more than 45,000 greyhound races over an eight year period at Dairyland Greyhound Park to test for and examine the nature of the favorite-longshot bias. While the longest odds dogs are collectively found to be over-bet for the sample as a whole, the bias is found to diminish after the introduction of Off-Track Betting. Further, maiden races, among inexperienced dogs, are shown to exhibit the traditional favorite-longshot bias, while non-maiden races do not. These results may help explain why researchers have found the bias at some tracks, but not others.
REVISITING THE “HOT HAND” HYPOTHESIS IN THE NBA BETTING MARKET USING ACTUAL SPORTSBOOK BETTING PERCENTAGES ON FAVORITES AND UNDERDOGS
Authors: Paul Rodney J , Weinbach Andrew P , Humphreys Brad 
Published: August 2020

The “hot hand” hypothesis was first investigated in sports betting markets by Camerer (1989) and Brown and Sauer (1993), who examined if professional basketball teams truly could become “hot”, implying a change in their actual skill level, and if the betting market believes teams become “hot” and over bet the teams on winning streaks. Both assumed that book makers operated a balanced book. Recent evidence suggests that book makers do not set point spreads to balance betting on either side of games. Book makers may price as a forecast or shade point spreads to exploit known biases. The “hot hand” could exist, but closing point spreads may not reflect this bias due to an unbalanced book. Using a 6 season sample of NBA betting market data, we show wagering against the “hot hand” does not win more than implied by efficiency. However, OLS and two-stage least squares regression models show that bettors believe in the hot hand, as teams on streaks attract a significantly higher number of bets. This illustrates that the public believes in the hot hand, reflecting an actual behavioral bias. This bias exists even though the closing price serves as an optimal and unbiased forecast of outcomes.

Published: August 2020

This work reports the structure, electrical and magnetic properties of the orthorhombic (Pbam) structured bulk Bi2Fe4O9 synthesized by the solid-state reaction process. Bi2Fe4O9 has been studied using several experimental techniques such as X-ray diffraction, scanning electron microscopy, Raman spectroscopy, dielectric spectroscopy, and magnetometry. Rietveld-refined X-ray diffraction data and Raman spectroscopy results clearly reveal the formation of Bi2Fe4O9 perovskite structure and all the peaks of Bi2Fe4O9 perfectly indexed in the orthorhombic (Pbam) structure. It has been established that the Raman spectrum identified Ag, B2g, and B3g active optical phonon modes, and that the Raman peak at 470 cm−1 may have a magnetic origin. As a result, the coexistence of weak ferromagnetic and antiferromagnetic orders in Bi2Fe4O9 ceramic was established. The remanent magnetization (2Mr) and coercivity (2Hc) are 8.74 × 10−4 emu/g and 478.8 Oe, respectively. We report a remarkable multiferroic effects in polycrystalline Bi2Fe4O9 ceramic. These characteristics make this material very useful in technology and practical applications.
Percepción de los futuros maestros de primaria sobre el riesgo de inundación. La geografía como herramienta para lograr una sociedad más resiliente al cambio climático
Authors: Morote Seguido Álvaro Francisco 
Published: August 2020

El riesgo de inundación se trata del principal peligro natural que afecta a la región mediterránea europea. Este riesgo se ha agravado en las últimas décadas por el incremento de la exposición del ser humano, por ello, tratar estos temas en las aulas de Primaria y la formación de los maestros debe ser una prioridad. La hipótesis de partida de esta investigación es que el futuro profesorado de Primaria tiene la percepción de que el riesgo de inundación se ha agravado en los últimos años debido al cambio climático. Los objetivos de este trabajo son: 1) Conocer las experiencias vividas sobre inundaciones de los futuros maestros durante su formación escolar (Primaria); y 2) Analizar cuál es la percepción que tienen éstos sobre la influencia del cambio climático en la aseveración de las inundaciones. Metodológicamente se ha llevado a cabo una investigación de tipo mixta (cuantitativa y cualitativa) con la realización de un cuestionario a los futuros maestros de Primaria (caso de estudio de la Facultad de Magisterio; Universidad de Valencia). Los resultados indican que la percepción de los encuestados es que la mayoría de sus centros escolares no se situaban en zonas inundables y, respecto al cambio climático, el 50% cree que está afectando al régimen actual de las precipitaciones.
The risk of flooding is the main natural hazard that affect the European Mediterranean region. This risk has been aggravated in recent decades by the increase in exposure of the human being. Therefore this theme should be a priority in primary classrooms and the training of teachers. The hypothesis of this research is that the future teachers of Primary school have the perception that the risk of flooding has worsened in recent years due to climate change. The objectives of this work are: 1) To know the experiences of floods of future teachers during their school education (Primary school); and 2) Analyze their perception of the influence of climate change in the assertion of flood risk. Methodologically, a mixed research (quantitative and qualitative) was carried out with the completion of a questionnaire to future teachers of Primary (Faculty of Education, University of Valencia). The results indicate that the perception of the respondents is that most of their schools were not located in flood zones and, with respect to climate change, in 50% of the cases they believe that it is affecting the rainfall regime.

The anthropization of the vegetation cover in the landscapes of Chiapas state, Mexico Cuatro años después de la catástrofe, ¿Están los centros educacionales de la Región de Murcia en España preparados para el próximo desastre sísmico?El objetivo de la presente investigación es conocer y evaluar los niveles de modificación antrópica sobre la cobertura vegetal de los paisajes del estado de Chiapas, México. Para cumplir con este objetivo se aplicó un índice de presión al mapa de los paisajes físico-geográficos del estado de Chiapas, a escala 1: 250 000. Los resultados indican que la categoría baja ocupa el 29% de la superficie estatal; la clase alta 27%; el nivel medio 26%; la categoría muy baja 16%; finalmente, el nivel muy alto abarca 2%. La categoría alta se ubica en paisajes de planicie, piedemonte y valle, en clima cálido húmedo y cálido subhúmedo. La clase baja se localiza en montañas de origen tectónico-intrusivo,tectónico-acumulativo y tectónico-kárstico, en climas templado, semicálido húmedo a subhúmedo y cálido húmedo. El escenario de tendencia es preocupante, porque la categoría alta podría representar en el corto plazo 53% de la superficie estatal.

To achieve this goal, a pressure index was applied to the map of the physical-geographical landscapes of the Chiapas State, in a 1: 250 000 scale. The results indicate that low category occupies 29% of the surface area of the state; the high class 27%, the medium level 26%, the very low category 16%; finally, the very high level covers 2%. The high category is located in plains, piedmonts and valley landscapes in warm humid and subhumid climate. The low class is located in mountains of tectonic-intrusive, tectonic-acumulative and tectonic-karstic origin, in temperate, semi-warm humid to subhumid, and warm humid climates. The trend scenario is worrisome, because the high level could represent in the short term 53% of the surface area of the state.

Published: August 2020

BackgroundReproductive biology and the evolutionary constraints acting on dispersal stages are poorly understood in many stony coral species. A key piece of missing information is egg and sperm gene expression. This is critical for broadcast spawning corals, such as our model, the Hawaiian speciesMontipora capitata, because eggs and sperm are exposed to environmental stressors during dispersal. Furthermore, parental effects such as transcriptome investment may provide a means for cross- or trans-generational plasticity and be apparent in egg and sperm transcriptome data.MethodsHere, we analyzedM. capitataegg and sperm transcriptomic data to address three questions: (1) Which pathways and functions are actively transcribed in these gametes? (2) How does sperm and egg gene expression differ from adult tissues? (3) Does gene expression differ between these gametes?ResultsWe show that egg and sperm display surprisingly similar levels of gene expression and overlapping functional enrichment patterns. These results may reflect similar environmental constraints faced by these motile gametes. We find significant differences in differential expression of egg vs. adult and sperm vs. adult RNA-seq data, in contrast to very few examples of differential expression when comparing egg vs. sperm transcriptomes. Lastly, using gene ontology and KEGG orthology data we show that both egg and sperm have markedly repressed transcription and translation machinery compared to the adult, suggesting a dependence on parental transcripts. We speculate that cell motility and calcium ion binding genes may be involved in gamete to gamete recognition in the water column and thus, fertilization.

Published: August 2020

Background
Lipid metabolism factors may play an important role in the progression of nonalcoholic fatty liver disease (NAFLD) and its related cardiovascular dysfunctions. The study aims to assess whether Apolipoprotein A-1 (ApoA1) was associated with vascular stiffness in NAFLD patients.

Methods
From 2012 to 2013, we included 2,295 non-alcohol users with fatty liver disease (1,306 male patients) and completely excluded subjects who drank any alcohol ever to eliminate the effect of alcohol intake. The serum ApoA1 levels and the brachial-ankle pulse wave velocity (baPWV) were measured.

Results
The baPWV in men was much higher than in female patients (1,412.79 cm/s vs. 1,358.69 cm/s, P < 0.001). ApoA1 level was positively associated with baPWV odd ratio (OR), 4.18; 95% confidence interval (CI) [1.16–15.1], P < 0.05) in patients with AST/ALT < 1 and (OR, 4.70; 95% CI [1.36–16.23], P < 0.05) in patients with AST/ALT ≥ 1 respectively. Only arterial stiffness in men was associated with ApoA1 (OR, 3.96; 95% CI [1.29–12.30], P < 0.05) in logistics regression models adjusted for age, gender, body mass index, education attainment, physical activity, smoking, history of hypertension and high-density lipoprotein. The relationship between ApoA1 and baPWV in male NAFLD patients remained significant (confidence, 156.42; 95% CI [49.34–263.50], P < 0.05) in the fully adjusted linear regression model.

Conclusion
The serum ApoA1 was associated with arterial stiffness in male NAFLD patients. Increased ApoA1 level should be considered as an independent risk factor for arterial stiffness in male NAFLD patients, suggesting that NAFLD may alter arterial stiffness by “ApoA1-related” mechanism in men.
Significance of hub genes and immune cell infiltration identified by bioinformatics analysis in pelvic organ prolapse
Authors: Zhao Ying , Xia Zhijun , Lin Te , Yin Yitong 
Published: August 2020

Objective
Pelvic organ prolapse (POP) refers to the decline of pelvic organ position and dysfunction caused by weak pelvic floor support. The aim of the present study was to screen the hub genes and immune cell infiltration related to POP disease.

Methods
Microarray data of 34 POP tissues in the GSE12852 gene expression dataset were used as research objects. Weighted gene co-expression network analysis (WGCNA) was performed to elucidate the hub module and hub genes related to POP occurrence. Gene function annotation was performed using the DAVID tool. Differential analysis based on the GSE12852 dataset was carried out to explore the expression of the selected hub genes in POP and non-POP tissues, and RT-qPCR was used to validate the results. The differential immune cell infiltration between POP and non-POP tissues was investigated using the CIBERSORT algorithm.

Results
WGCNA revealed the module that possessed the highest correlation with POP occurrence. Functional annotation indicated that the genes in this module were mainly involved in immunity. ZNF331, THBS1, IFRD1, FLJ20533, CXCR4, GEM, SOD2, and SAT were identified as the hub genes. Differential analysis and RT-qPCR demonstrated that the selected hub genes were overexpressed in POP tissues as compared with non-POP tissues. The CIBERSORT algorithm was employed to evaluate the infiltration of 22 immune cell types in POP tissues and non-POP tissues. We found greater infiltration of activated mast cells and neutrophils in POP tissues than non-POP tissues, while the infiltration of resting mast cells was lower in POP tissues. Moreover, we investigated the relationship between the type of immune cell infiltration and hub genes by Pearson correlation analysis. The results indicate that activated mast cells and neutrophils had a positive correlation with the hub genes, while resting mast cells had a negative correlation with the hub genes.

Conclusions
Our research identified eight hub genes and the infiltration of three types of immune cells related to POP occurrence. These hub genes may participate in the pathogenesis of POP through the immune system, giving them a certain diagnostic and therapeutic value.

Authors: Tomar Shubhi , Tiwari Rajnarayan R. , Verma Garima 
Published: August 2020

AbstractBackgroundThe Indian hair and beauty salon industry is growing rapidly due to the demand for beauty and personal care services and products. Workers in the industry are vulnerable to several occupational factors such as chemicals, confined space, and poor ventilation. Chemicals in the products used are known or suspected to cause allergies, respiratory, neurological and reproductive health problems and cancer.MethodsThe present study was carried out to determine the factors associated with the occurrence of respiratory morbidity among hair and beauty salon workers of Udupi taluk, Karnataka, India. A total of 240 salon workers were recruited for the study. A semistructured, interviewer‐led questionnaire was used to collect data. Peak expiratory flow rate (PEFR) was done using a JSB peak flow meter.ResultsThe frequency of respiratory morbidity among participating beauty salon workers was 19%. Men reported respiratory symptoms more frequently than women. Receiving training on work materials and practices was a significant protective factor (odds ratio = 0.3; 95% confidence interval: 0.1‐0.7) for the occurrence of respiratory morbidity. The mean observed PEFR in these workers was significantly lower than their predicted values. While 61.2% of the workers were using some form of personal protective equipment, only 4% of workers used a mask or respiratory protection.ConclusionHair and beauty salon workers are at risk of developing respiratory morbidity potentially from harmful exposures and lack of effective control measures at the workplace.
A Non‐aqueous H3PO4 Electrolyte Enables Stable Cycling of Proton Electrodes

Published: August 2020

AbstractA non‐aqueous proton electrolyte is devised by dissolving H3PO4 into acetonitrile. The electrolyte exhibits unique vibrational signatures from stimulated Raman spectroscopy. Such an electrolyte exhibits unique characteristics compared to aqueous acidic electrolytes: 1) higher (de)protonation potential for a lower desolvation energy of protons, 2) better cycling stability by dissolution suppression, and 3) higher Coulombic efficiency owing to the lack of oxygen evolution reaction. Two non‐aqueous proton full cells exhibit better cycling stability, higher Coulombic efficiency, and less self‐discharge compared to the aqueous counterpart.
Representatives of future generations as promoters of sustainability in corporate decision processes
Authors: Bogacki Julia , Letmathe Peter 
Published: August 2020

AbstractCurrent protests of the young generation emphasize that interests of future generations should be taken more into account by policy makers and in corporate decision processes. As organizations contribute to enduring environmental and social problems, they are required to promote sustainability in order to preserve options for the well‐being of future generations. However, organizational decision makers often take a short‐term perspective and neglect investments in intergenerational justice. Previous theoretical work has acknowledged the importance of representing future generations in today's decision‐making processes to adopt a long‐term perspective in order to promote intergenerational justice. In a laboratory experiment, we show that appointing representatives of future generations at the organizational level can foster investments in intergenerational justice. Although this outcome is more pronounced when aligned with the representatives' individual incentives, it even persists for a representative who is monetarily penalized for advocating the interests of future generations.
Elucidating Atropisomerism in Nonplanar Porphyrins with Tunable Supramolecular Complexes
Authors: Norvaiša Karolis , O'Brien John E. , Gibbons Dáire J. , Senge Mathias O. 
Published: August 2020

AbstractAtropisomerism is a fundamental feature of substituted biaryls resulting from rotation around the biaryl axis. Different stereoisomers are formed due to restricted rotation about the single bond, a situation often found in substituted porphyrins. Previously NMR determination of porphyrin atropisomers proved difficult, if not almost impossible to accomplish, due to low resolution or unresolvable resonance signals that predominantly overlapped. Here, we shed some light on this fundamental issue found in porphyrinoid stereochemistry. Using benzenesulfonic acid (BSA) for host‐guest interactions and performing 1D, 2D NMR spectroscopic analyses, we were able to characterize all four rotamers of the nonplanar 5,10,15,20‐tetrakis(2‐aminophenyl)‐2,3,7,8,12,13,17,18‐octaethylporphyirin as restricted H‐bonding complexes. Additionally, X‐ray structural analysis was used to investigate aspects of the weak host–guest interactions. A detailed assignment of the chemical signals suggests charge‐assisted complexation as a key to unravel the atropisomeric enigma. From a method development perspective, symmetry operations unique to porphyrin atropisomers offer an essential handle to accurately identify the rotamers using NMR techniques only.

AbstractSmoking is a major contributor to lung cancer and chronic obstructive pulmonary disease (COPD). Two of the strongest genetic associations of smoking‐related phenotypes are the chromosomal regions 15q25.1, encompassing the nicotinic acetylcholine receptor subunit genesCHRNA5‐CHRNA3‐CHRNB4, and 19q13.2, encompassing the nicotine metabolizing geneCYP2A6. In this study, we examined genetic relations between cigarettes smoked per day, smoking cessation, lung cancer, and COPD. Data consisted of genome‐wide association study summary results. Genetic correlations were estimated using linkage disequilibrium score regression software. For each pair of outcomes, z‐score‐z‐score (ZZ) plots were generated. Overall, heavier smoking and decreased smoking cessation showed positive genetic associations with increased lung cancer and COPD risk. The chromosomal region 19q13.2, however, showed a different correlational pattern. For example, the effect allele‐C of the sentinel SNP (rs56113850) withinCYP2A6was associated with an increased risk of heavier smoking (z‐score = 19.2;p = 1.10 × 10−81), lung cancer (z‐score = 8.91;p = 5.02 × 10−19), and COPD (z‐score = 4.04;p = 5.40 × 10−5). Surprisingly, this allele‐C (rs56113850) was associated with increased smoking cessation (z‐score = −8.17;p = 2.52 × 10−26). This inverse relationship highlights the need for additional investigation to determine howCYP2A6variation could increase smoking cessation while also increasing the risk of lung cancer and COPD likely through increased cigarettes smoked per day.
