Fallacy Bias in Casino Gaming
Authors: Min Yingkai , Nong Sunny Zhenzhen , Fong Lawrence Hoc Nang , Wu Anise Man Sze
Published: December 2023

Fallacy bias is salient in gamblers’ minds and plays a crucial role in motivating gamblers to bet. The bias stems from people’s misconception that independent outcomes are autocorrelated. It makes an indirect but significant contribution to the revenue of casinos. However, from the perspective of corporate social responsibility, casinos should not indulge the bias. To strike the balance, casino practitioners need to understand the triggering factors of fallacy bias and whether the bias varies with gamblers’ characteristics. While gamblers’ racial difference in fallacy bias remains unknown, this study adopted non-participatory observation and analyzed the bets of 501 non-Asian and 206 Asian Roulette gamblers in an Australian casino. Results showed that non-Asian players had a stronger tendency towards gambler’s fallacy than their Asian counterparts. The influences of length and frequency of the latest outcome on the betting decisions did not vary with race. The findings provide useful implications for casino management.
Betting Market-Based Expectations and NFL Coach Retention and Dismissal
Authors: Paul Rodney J. , Weinbach Andrew P. , Wilson Mark
Published: December 2023

Performance compared to expectations is important in evaluation of Chief Executive Officers, managers, and coaches. In many industries, expectation metrics are difficult to estimate or obtain. In professional sports, however, futures markets exist for season performance. In many sports, such as the NFL, there exists a wagering option on season win totals. A season win total is an over/under bet on the number of wins a team will have in a given season. We utilize this market to calculate actual versus expected performance and include this in a model of coach retention. The issue of treatment discrimination of minority coaches is explored.
Bayesian Assessment of Casino Promotions
Authors: Singh Ashok K.
Published: December 2023

Casinos use Cash (Free Play), Direct Mail and E-Mail Blasts, Buffet coupons, and Hotel Marketing among other offers in order to retain their loyal customers and also to invite new players to join their loyalty club. This study assessed the effectiveness of such promotions in terms of generated gaming revenues. Data from two mid-size casinos are used for this purpose. The method of Bayesian general linear models is used to determine the effects of various promotions on gaming revenue streams. Several promotion types were shown to have a significant impact on gaming revenue streams.
Power Imbalances, Market Concentration, and High Jackpots: The Case of EuroMillions
Authors: Muñiz Álvaro
Published: December 2023

While the EuroMillions game has been in operation since 2004, there has been limited analysis of its demand and no research on potential power imbalances within the organization and their dependence on jackpot size. This study utilizes EuroMillions sales data at the country level to examine the distribution of market power within the organization and its historical trends. Market concentration is evaluated using the Herfindahl Hirschman index (HHI), and the relationship between the HHI and jackpot size is assessed using sales data at the draw level for all game operators. Findings indicate that power imbalances exist within the EuroMillions organization, partly due to the impact of the jackpot size, which appears to stimulate demand for EuroMillions tickets more in certain countries than in others.

Bitcoin Versus Gold Prices: Correlation or Mis-specification
Authors: Kumar Praveen
Published: December 2023

Bitcoin is a newly created currency, which is also considered as “Digital Gold.” Whereas, Gold is a precious yellow metal. Bitcoins are more independent of the government than gold. Both gold and bitcoins are scanty resources, and thus, prices of both these assets appreciate or deteriorate depending on the demand and supply. An attempt was made to examine the association between prices of these two currencies. For this purpose, three different models were run: independent sample t-test, correlation analysis, and regression analysis. The outcomes of the independent sample  t-test revealed that there exists a significant difference between the gold and bitcoin prices. However, the findings of correlation analysis show that movements in gold prices are statistically and positively linked to bitcoin prices. These findings indicate that gold prices move in the same direction as bitcoin prices. Further, the results of regression analysis also depicted that movement of bitcoin prices depends on movement of gold prices. Since its genesis, bitcoin prices have experienced around 37,418 appreciations, which make it an extraordinary currency. However, this study argued that bitcoin is establishing itself as an investment asset for the short term only because fluctuation in prices is very abnormal and unreliable in the long run. Moreover, robustness checks further show that gold prices are increasing at a steady rate, but increments are regular and trustworthy. Finally, the study found that bitcoin provides much higher returns to investors than gold. These results are crucial for the risk-taker investors who are looking for higher returns because bitcoins are getting growing public exposure day by day and attracting investments throughout the world.

Erstrittene Freiheit zwischen Kaiser und Fürstenherrschaft
Authors: Haas Philip , Schürrer Martin
Published: December 2023

Städte zwischen Kaiser und Fürst: Ein dritter Städtetyp in der Frühen Neuzeit, betrachtet am Beispiel Einbecks und des Sächsischen Städtebundes. Lange galt die Frühe Neuzeit in stadthistorischer Sicht als »Städtetal« - eine Zeit mit nur wenigen Neugründungen. Allerdings bildeten sich bestimmte Städtetypen erst in dieser Zeit heraus. Für das Heilige Römische Reich wird zwischen Reichsstädten und Landstädten unterschieden: Unterstanden erstere unmittelbar dem Kaiser, so waren letztere einem Landesherrn untertan. Im vordergründig »reichsfernen« Norddeutschland existierte ein dritter Städtetyp, den die Zeitgenossen als civitas mixta bezeichneten und für den die Geschichtsforschung den Begriff Autonomiestadt prägte, ohne ihn genauer zu bestimmen. Diese Autonomiestädte waren kein Überbleibsel des Mittelalters, sondern etablierten sich erst im 16. Jahrhundert. Am Beispiel Einbecks und des Sächsischen Städtebunds betrachten Philip Haas und Martin Schürrer erstmals eingehend diesen Städtetyp, arbeiten dessen Strukturmerkmale heraus und zeichnen Entwicklungslinien nach. Dies geschieht unter Rückgriff auf eine Vielzahl archivalischer Quellen und unter Auswertung der gelehrten frühneuzeitlichen Publizistik. Durch Anpassung etablierter und Nutzung innovativer politischer Werkzeuge konnten sich Autonomiestädte bis weit in das 17. Jahrhundert behaupten.
New Developmentalism: What Do We Know and Where Are We Going?
Authors: Oriol Ettore de Carvalho , Martins Humberto Falcão
Published: December 2023

Studies focusing on the theory of New Developmentalism have been growing in recent years. This has happened since the great crisis of Neoliberalism in 2008, which pointed to the exhaustion of the financial-rentier Neoliberal model as a solution to issues related to the development of countries. Based on this diagnosis, we proposed a bibliometric analysis that shows the past, the present, and the future possibilities (trends) within the field of New Developmentalism. For the execution of this Bibliometrics, we searched for the articles published and indexed in the Web of Science and Scopus databases using the search term "New Developmentalism". The result pointed to 749 published articles. The search used the term in all the search fields available in the databases, excluding no possibilities. These data were treated in “Biblioshiny” within the RStudio software and the results were analyzed to generate a mapping of the field of study. The results of this study show that this is still a new field of study and that it needs a lot of research to reach maturity. An even more evident gap is the scarcity of studies that address the macroeconomic prices important for the growth of national economies, as pointed out by the New Developmentalism Theory of Brasser-Pereira. In this gap, we identify arguments contrary to the theory that need to be addressed and empirically researched to be accepted or refuted. By working this gap, we would bring light to points not yet explored and enrich the discussions. The problem of the role of the State as a promoter of the conditions for the economic development of countries, in contrast to the Neoliberalism that advocates a minimal State, is also an aspect little explored by empirical articles, requiring further study. Another important point that needs to be addressed is the incorporation of the ecological and social agenda, especially that of income distribution in the studies of the application of the New Developmentalism Theory. In this gap, the inclusion of the third sector in the New Developmentalism Theory as an agent distinct from the State and the Market could be a solution and an innovation. The third sector's principle is to promote and bring about structural changes in society that are very important for the economic and social development of countries. This inclusion helps in the expansion of income distribution and social development processes that the State, based on rules (Bureaucracy), and the Market, based on profit (competition), are unable to accomplish. We also identify the need for a more particularized delineation of the identification of New Developmentalism Theory, generating a label that does not confuse with other theories. Thus, we seek to contribute to the field of study by showing the advances made so far and pointing out directions that can be followed by other researchers who wish to expand the study of New Developmentalism Theory.

Authors: Herrero Ingelmo José Luis
Published: December 2023

Se estudian algunas metáforas vegetales cosificadoras en español, basadas en objetos puntiagudos (sobre todo, la aguja, el alfiler y el gladiolo). Se utiliza la base de datos de Flora ibérica (http://www.floraiberica.es), proyecto iniciado en 1980 desde el Real Jardín Botánico (CSIC, Madrid) que estudia «las plantas vasculares que crecen espontáneamente en la Península Ibérica e Islas Baleares» (está excluida, por tanto, la flora americana, tan rica e interesante). También se hace referencia al tratamiento que hace de estas metáforas, cuando las recoge, el diccionario académico, que las consagra como nombre «general» de una planta.
La influencia e importancia del léxico comercial del español de los Países Bajos a partir de un corpus de cartas del siglo XVII
Authors: Sánchez Vicente Andrea
Published: December 2023

El presente artículo analiza un corpus de cartas comerciales del siglo XVII escritas desde Ámsterdam por cuatro mercaderes neerlandeses en español. La investigación se centra en cuatro voces encontradas en este corpus (paquetboot, paca, flete y entrepresa) que no solo se erigen como la primera (paquetboot) o última (entrepresa) datación conocida de estas palabras, sino que también evidencian la difusión del préstamo del neerlandés al francés y del francés al español (paca, flete). Asimismo, también demuestran que la correspondencia comercial refleja los movimientos migratorios mercantiles, lo que ofrece una valiosa oportunidad para investigar el cambio lingüístico a través del tiempo.

Development of effective XGB model to predict the Axial Load Capacity of circular CFST columns
Authors: Indra Prakash  , Raghvendra Kumar  , Nguyen Thuy-Anh , Phuong Thao Vu
Published: December 2023

The Axial Load Capacity (ALC) of Concrete-Filled Steel Tubular (CFST) structural members is regarded as one of the most crucial technical factors for the design of these composite structures. This work proposes the development and application of the Extreme Gradient Boosting (XGB) model to forecast the ALC of circular CFST structural components using the affecting input parameters, namely column diameter, steel tube thickness, column length, steel yield strength, and concrete compressive strength.  A dataset of 2073 experimental results from the literature was used for the model development. The performance of the XGB model was evaluated using statistical criteria such as Root Mean Square Error (RMSE), Mean Absolute Error (MAE), Coefficient of Determination (R2), and Mean Absolute Percentage Error (MAPE). The five-fold cross-validation technique and Monte Carlo simulation method were used to evaluate the model's performance. The results show good performance of the XGB model (R2 = 0.999, RMSE = 242.757 kN, MAE = 157.045 kN, and MAPE = 0.057) in predicting the circular CFST’s ALC.

Authors: Ngo Quoc Trinh , Nguyen Linh Quy , Quan Van Tran
Published: December 2023

The materials left behind after the process of separating an ore's valuable fraction from the unprofitable fraction are known as tailings in the mining industry. Mixing tailing, cement and water can create a new material called Cemented paste backfill (CPB). Research and solve the problem of predicting the tensile strength of cement paste backfill based on a polynomial model combined with the Monte Carlo Simulation method. Three models were built to evaluate performance. The optimal performance model is then used to predict the tensile strength of cement paste backfill. The results indicate that using the polynomial regression model has a satisfactory result for predicting the tensile strength of cement paste backfill. The best performance of second order polynomial regression model is evaluated by three metrics such as R2=0.958 RMSE=33.211 kPa MAE=29.097 kPa for testing part in predicting the tensile strength of cemented paste backfill. Finally, the influence of Cement/Tailings ratio and Solid content on the tensile strength on tensile strength and importance is also evaluated with aid of the best performance of second order polynomial regression model.

Authors: Nguyen Hoang Quan , Vu Minh Duc , Nguyen Thi Phuong , Le Ngoc Ly , Nguyen Thi My Trang
Published: December 2023

The linear buckling behavior of functionally graded cylindrical shells with porous core stiffened by spiral stiffeners under axial compression using the first-order shear deformation theory is presented in this paper. The improved Lekhnitskii’s smeared stiffeners technique is applied for shear deformable spiral FGM stiffeners. Approximate analytical solutions are assumed to satisfy the simply supported boundary conditions and the adjacent equilibrium criterion is applied to obtain closed-form relations of buckling loads. Effects of the number of FGM stiffeners, stiffener angle, volume fraction index and porosity coefficient on the buckling behavior of shells are numerically investigated.
Effect of weather aging on volume expansion properties of steel slag
Authors: Trinh Hoang Son
Published: December 2023

Steel slag, one of the huge industrial waste sources, which has many outstanding advantages (hardness, roughness, angularity, and abrasion resistance) has been used as an aggregate in asphalt concrete to bring many benefits. However, steel slag is rarely used in Portland cement concrete because of concerns that it may give rise to volume expansion. One of the main causes of this problem is that the steel slag contains a considerable amount of free lime. This free lime content can be reduced if it is hydrated or the steel slag is aged by water. Therefore, in this study, the effects of weather aging on volume expansion properties of steel slag will be considered. The pH, free lime and volume expansion tests were carried out on weather-aged steel slag samples (after aged by 1 month, 6 months, 12 months and 30 months) and compared with non-aged one. The results showed that the 6 month-aged, 12 month-aged, and 30 month-aged steel slag samples had low free content, low pH and volume expansion. Moreover, steel slag aged more than 6 months has very low volume expansion, meeting the requirements of ASTM D492 for use as aggregate in concrete.
Application of secure semi-supervised fuzzy clustering in object detection from remote sensing images
Authors: Pham Quang Nam , Nguyen Long Giang , Le Hoang Son , Tran Manh Tuan
Published: December 2023

In recent years, landslides are taking place very seriously, and tend to increase in both scope and scale, threatening people's lives and properties. Therefore, timely detection of landslide areas is extremely important to minimize damage. There are many ways to detect landslide areas, in which the use of satellite images is also an option worthy of attention. When performing satellite image data collection, there are many outliers, such as weather, clouds, etc. that can reduce image quality. With low quality images, when executing the clustering algorithm, the best clustering performance will not be obtained. In addition, the fuzzy parameter is also an important parameter affecting the results of the clustering process. In this paper will introduce an algorithm, which can improve the results of data partitioning with reliability and multiple fuzzifier. This algorithm is named TSSFC. The introduced method includes three steps namely as “labeled data with FCM”, “Data transformation”, and “Semi supervised fuzzy clustering with multiple point fuzzifiers”. The introduced TSSFC method will be used for landslide detection. The obtained results are quite satisfactory when compared with another clustering algorithm, CS3FCM (Confidence-weighted Safe Semi-Supervised Clustering).

introduction: Malnutrition includes both undernutrition and overnutrition. Child undernutrition is a major global health problem that is more common in low-income countries like Sudan, it can cause childhood morbidity, mortality, and impaired intellectual development. Objective: This study was conducted to assess the outcome of malnourished children treated with ready to-Use Therapeutic Food (RUTF), and ready to-Use Supplementary Food (RUSF) in Wad Elbasheir Health Centre in Ombada Locality Methods: This is an analytical Cross-Sectional facility-based Study conducted at Wad Elbasheir Health Centre. A convenient nonprobability sampling technique was used in this study. Data were collected using a datasheet after being pretested. Data were collected from secondary data from the records of malnourished children treated by the RTUF and RUSF. Results: The majority of the participants of this study were aged between 6 to 23 months (84%) and most of the participants were females (56%). This study showed that 70 (24%) of the participants were classified as severe Acute Malnutrition (SAM), while 218 (76%) were classified as moderate Acute malnutrition (MAM). This study showed that having a smaller number of children in the family and middle Upper Arm Circumference (MUAC) between 11.5-12.5 cm were more associated with recovery. Moreover, this study showed that children who use amoxicillin or anti-worms were more likely to be recovered from malnutrition. Conclusion: RUTF was designed for the nutritional management of children with uncomplicated acute malnutrition treated as outpatients. In this study, most of the children recovered. In addition, this study found that several factors were associated with better outcomes including fewer children in the family, MUAC between 11.5-12.5 cm, having MAM (compared to having SAM), and using amoxicillin or anti-worms.

On construction of the canonical form on the frame bundle
Authors: Kuleshov A.V.
Published: December 2023

The detailed description of the construction of the canonical form on the higher order frame bundle over an n-dimensional smooth manifold is given. In particular, it is shown that some vector space isomorphism play­ing the key role in this construction is defined correctly, i. e. it depends only on the frame of order p + 1 and does not depend on the choice of its representative, i. e. a local diffeomorphism which (p + 1)-jet is exactly this frame. This isomorphism acts from the direct sum of n-dimensional arithmetic space and the Lie algebra of the p-th order differential group to the tangent space to the p-th order frame bundle over the manifold at the p-th order frame lying “below”. The action of this isomorphism can be splitted into two its restrictions. The first one acts from the first direct sum­mand, and the second one acts from the second direct summand. It is shown that the first restriction depends only on the choice of the (p + 1)-fra­me, while the second one is closely related to fundamental vector fields and therefore does not depend of this frame at all.

By affine connectivity of the com­mon path space, we construct an affine connection on the tangent bundle. For the infinitesimal transformation of the tangent bundle, a system of in­va­riance equations for the constructed affine connectivity is compiled. This system is a system of second-order differential equations with res­pect to the components of the infinitesimal transformation. The main re­sults of the article are obtained by analyzing this system taking into account the properties of homogeneous functions. It is shown that the comp­lete lift of an infinitesimal transformation of base is an infinitesimal af­fine motion of a tangent bundle if and only if the infinitesimal transfor­ma­tion of base is an affine motion in the general path space. Necessary and sufficient conditions are found that the infinitesimal transformation of a tangent bundle generated by a vertical vector field leaves the affine connec­ti­vity of the tangent bundle invariant. Conditions are given that are neces­sa­ry and sufficient so that the infinitesimal transformation of a tangent bundle with affine connectivity that preserves layers is an affine motion.
Relationship of Adiponectin and High-Sensitivity CReactive Protein with Left Ventricular Dysfunction among Patients Undergoing Coronary Angiography
Authors: Al-Hakimi Mohammed S.
Published: December 2023

Background: Decreased levels of adiponectin (APN) and elevated levels of high-sensitivity C-reactive protein (hs-CRP) have been found as predictors of left ventricular dysfunction and cardiovascular events. Therefore, this study aimed to assess the relationship of APN and hs-CRP with the severity of left ventricular dysfunction among Egyptian patients undergoing coronary angiography (CAG).

Methods: A cross-sectional study was conducted among 100 Egyptian patients who underwent clinically indicated CAG at Suez Canal University Hospital in Ismailia - Egypt, from May 2009 to December 2010. The left ventricular ejection fraction (LVEF) scoring system was used to assess left ventricular function based on echocardiographic findings. Pearson correlation was used to determine the relationship of APN and hs-CRP levels with echocardiographic LVEF score, and analysis of variance (ANOVA) was used to compare clinical and biochemical parameters among patients according to left ventricular function at P-value <0.05.

Results: The mean hs-CRP level had a significant weak negative correlation with the mean HDL-cholesterol level (r = -0.222; P = 0.048), while the mean APN level had a significant weak negative correlation with BMI (r = -0.269; P = 0.007) but a significant weak positive correlation with the mean hs-CRP level (r = 0.215; P = 0.031) and a significant moderate positive correlation with the mean HDL-cholesterol level (r = 0.302; P = 0.002). Left ventricular function in patients undergoing CAG was normal in 34 (34%), mildly impaired in 41 (41%) patients and moderately impaired in 25 (25%), with significantly different mean hs-CRP levels among the three groups (P = 0.025) that increased from normal to moderately impaired left ventricular function. However, there was no statistically significant difference in left ventricular function according to the mean level of APN.

Conclusion: The hs-CRP level is negatively correlated with HDL-cholesterol, while APN is negatively correlated with BMI and hs-CRP but positively correlated with HDL-cholesterol in Egyptian patients undergoing CAG. The hs- CRP level correlates with the severity of left ventricular dysfunction. However, left ventricular function does not appear to correlate with APN levels.

Đặt vấn đề: Ở Việt Nam, Húng quế (Ocimum basilicum L.) thường được dùng như rau ăn, có ít công bố về hiệu quả kiểm soát bệnh đái tháo đường. Mục tiêu: Xác định cao chiết tiềm năng từ lá cây Húng quế có tác dụng cải thiện các chỉ số creatinine, BUN (Blood urea nitrogen) trong huyết tương và malondialdehyde (MDA, marker của peroxy hóa lipid), glutathione (GSH) trong thận chuột bị đái tháo đường. Đối tượng và phương pháp: Cao chiết cồn 45% hoặc 96% từ lá Húng quế được cho uống ở các liều tương đương với 1.25 g và 2.5 g dược liệu trên chuột được gây đái tháo đường bằng streptozotocin (STZ). Xác định nồng độ glucose, creatinine, BUN bằng các bộ kit thương mại. Hàm lượng malondialdehyde (MDA), glutathione (GSH) trong dịch đồng thể thận chuột được xác định bằng thử nghiệm acid thiobarbituric và thuốc thử Ellman. Kết quả: Ở chuột được tiêm STZ và cho uống cao chiết cồn 45% (360 mg/kg và 720 mg/kg) có nồng độ glucose, creatinine và BUN trong huyết tương giảm so với lô chứng bệnh. Cao chiết cồn 96% (230 mg/kg và 460 mg/kg) làm hạ glucose máu nhưng không làm thay đổi nồng độ creatinine và BUN. Cao chiết cồn 45% làm giảm MDA và tăng GSH trong thận chuột. Kết luận: Cao chiết cồn 45% từ lá cây Húng quế được chọn là cao tiềm năng, có tác dụng hạ đường huyết và bảo vệ thận chuột trước tổn thương oxy hóa.

Artificial Gravity on Earth-Mars Flights Reconsidered: the Mars Quartet
Authors: Ashworth Stephen
Published: December 2023

The well-known concept of rotating a spacecraft tethered to a counterweight in order to generate artificial gravity in interplanetary transit between Earth and Mars fails to meet the condition for stable rotation. The present author has himself unwittingly perpetuated the same design error. It is therefore necessary to reopen the question of whether artificial gravity can be provided on an astronaut mission to Mars which is subject to realistic mass constraints. An architecture is proposed which uses four spacecraft in flight together, here referred to as the Mars Quartet. It is hoped that this will prompt NASA not to exclude artificial gravity solutions from their Mars architecture studies currently in progress. The conclusions concerning the pyramid architecture of an overall space economy, addressed in an earlier paper, are found not to be affected.
