                        An Extreme Problem for a Volterra Type Integral Inclusion

                        M. A. Sadygov
                        In the work, we have studied the dependencies of the solutions to integral in-clusions from perturbation and investigated an extremal problem for integral inclusions. We obtained necessary and sufficient minimum conditions for ex-tremal problems of Volterra type convex inclusions. We also studied a non-convex extremal problem for the Volterra type inclusion. We obtained a high order necessary

                        Role of Regression to the Mean and Loss Aversion in Brazilian Soccer Club Performance

                        Leon Esquierro, Sergio Da Silva
                        Causal explanations are often favored to explain club performance in soccer tournaments, and the role that luck plays is usually neglected. Here, we consider three recent seasons of the first-division Brazilian soccer league to examine the relative importance to club success of loss aversion (a causal explanation) and regression to the mean (luck). We find that club performance depends on both, and quantify this finding.

                        Carbon Stocks in Aboveground and Belowground Biomass of Sub-Humid Tropical Forest in Southwestern Nigeria

                        Habeeb Ajibola Yusuf, Jesumbo Joseph Oludipe, Oluwatoyin Olajumoke Adeoye, Idowu Ezekiel Olorunfemi
                        This study aimed at estimation of carbon stocks in aboveground and below-ground biomass of sub-humid young forest land in south-western Nigeria. Different species of trees were analysed. Results gathered indicated that the forest studied had an average aboveground carbon stock of live trees as 0.00407 t. Terminalia superba (0.00698 t C) has the highest carbon stocks and diameter at breast height (Dbh) of 5.80 cm while Triplochiton

                        An Innovative GIS Method for Evaluating the Visibility of the Road Using the ArcMap-Tools

                        Azad Abdulhafedh
                        Road visibility is critical to motorists in making decisions such as stopping, slow downing, turning, entering a traffic stream from a driveway, or merging into traffic. Adequate visibility allows motorists the time they need to avoid vehicle crashes and conflicts and will help keep roadways operating safely and smoothly. Insufficient visibility is a significant factor in roadway crashes and near collisions. This paper utilizes th

                        Pricing European Option When the Stock Price Process Is Being Driven by Geometric Brownian Motion

                        Kebareng I. Moalosi-Court
                        This report is about modeling a European Option in general when the stock price process is being driven by geometric Brownian motion (gBm). The volatility parameter is used as an example of a basic estimator and simulated values of geometric Brownian motion hence exploring some of the properties that improve the accuracy of an estimator. The theory is then extended to estimate the volatility from real data by using t

                        The Impacts of Forest Plantation on Household’s Income

                        Tran Cuong, Tran Thi Quy Chinh, Yi Xie
                        This study uses differences in differences (DID) method combined with OLS regression to assess the impact of forest plantations on household income and livelihoods in rural areas of Bac Kan Province in Vietnam based on the 2017 household living standard field survey data and VRAFC 2011 database. Results indicated that forest plantations have no impact on improving the household’s income. This is explaine

                        Introduction: A major impediment to sustainable development, sexual assault imposes exorbitant costs on families, communities and economies. The objec-tive of the study was to identify the determinants of sexual violence in urban areas. Methodology: This is a cross-sectional descriptive study in the form of a survey of 501 households conducted on 17 and 20 May 2018 at Bongonga District in the Kampemba Health District in Lubumbashi

                        Vibrio cholerae: General Knowledge and Epidemiological Aspects

                        Vicento Diabeno, Erick Kamangu
                        Cholera is an infectious diarrheal disease, highly contagious transmitted by a gram-negative bacteria, Vibrio cholerae. The infectious strain is divided into two biotypes (El Tor and Classical) based on their phenotypic characteristics and three serotypes (Inaba, Ogawa, Hikojima) according to the antiserum agglutination test. The Hikojima serotypes form is very rarely found during an epidemic. To date, several studies have shown t

                        Identifying Factors That Hinder the Acceptance of Chinese Brands among US Consumers

                        Kathryn Virzi, Carol Parrington
                        China has become a major player in the global economy over the past decade. Recent political turmoil between China and the US coupled with the rising rates of China’s currency has prompted the Chinese government to invest in building brand equity among Chinese brand names (Si, 2014). In spite of mak-ing large financial investments, setting up corporate headquarters in the US, and receiving con

                        Duygu Sisek, Suleyman Turkseven, Suleyman Topal
                        The purpose of this study is to determine the allelopathic effects of extracts obtained by using liquid nitrogen from the plant of Antep radish (Raphanus sa-tivus L.) and little radish (Raphanus sativus L. var. radikula) on germination and seedling growth of sterile oats. The experiments were carried out in six groups with root, stem and root stem mixed extracts of radish plants (Antep and little radish). A novel metho
