    This dissertation explores how information systems can improve the understanding of the home field advantage (HFA) in professional sports leagues in the United States. The literature related to the HFA conceptual framework and the game location factor—which represents four major impacts on teams (crowd, learning, travel, and rules)—led to an investigation into whether a relationship exists between game results and spatial, temporal, and stadium attributes. These stadium attributes include field surface type, roof type (i.e., open, fixed, and retractable), time zone, and field orientation (e.g., N/S, E/W, NE/SW) for U.S. professional sports such as soccer, baseball, and football. Winning percentage, winning streak, and losing streak were examined for their effect on game outcome. Collectively, all league games were examined to assess the effects of spatial, and temporal stadium attributes. A logistic regression (LR) analysis of the National Football League (NFL), Major League Soccer (MLS), and Major League Baseball (MLB) shows evidence of a significant relationship between spatial orientation, temporal, and stadium attributes and the game results. The LR model consider as an improvement over the base model, and the results vary from one sport to another. An IT artifact (dashboard) operationalized the proposed model based on these results. The dashboard provides team decision-makers with information to help them understand their opponent’s in the next home or away game. The artifact could be an integral part of the decision-making process for coaches and managers in game preparation and management

    Universities take pride in the research their school produces, as it demonstrates their dedication to advancing knowledge and pushing the boundaries of various fields, not just STEM. Research by definition is an inquiry using current sources to guide and establish new facts in any field of study. Undergraduate student research falls under this umbrella of advancement and is a critical component of the research culture at any institution. A research paper includes four important sections: the abstract, introduction, methods, and results section. Each section takes the audience through the steps implemented by the student to answer their research question and conclude with their findings. Upon completion of the research paper, students open themselves up to the opportunity of publishing their work in academic research journals. This article aims to address how to write a research paper that is suitable for publication

    The impact of video-game on aggressive behaviors among adolescents in Saudi Arabia: a national study

    Get PDF
    Background: Children and teenagers frequently use video games as a form of entertainment. Although the middle east has one of the fastest-growing video game user populations, most studies need more national data to demonstrate the prevalence of playing video games and its effects on aggressive and mental health behaviours. Therefore, this study aimed to assess the prevalence of video game use and its association with aggressive behaviours among adolescents in Saudi Arabia.Methods: This was a community-based cross-sectional study involving males and females, aged 15-18 years, in both private and public secondary schools in the five main regions of Saudi Arabia. A modified aggression questionnaire comprised 29 items and scored on a 5-point Likert scale was electronically self-administered for each participant. This survey measured hostility, verbal aggression, physical aggression, and anger.Results: A total of 4,840 students participated in the study with an average age of 16.15±3.98 years. Males frequently played video games compared with females (p<0.0001). The average playing time per day was significant across males (p<0.0001). Females were more likely to show anger and hostility (p<0.0001 for both). However, males were more likely to show physical aggression (p<0.0001).Conclusions: Our study suggests that playing video games might associate with violent behaviours among adolescents in Saudi Arabia. This conclusion is supported by previous international studies. Increasing families’ awareness about video games and their impact on mental health and behaviours would help them identify their benefits and drawbacks

    Cardea: An Open Automated Machine Learning Framework for Electronic Health Records

    Full text link
    An estimated 180 papers focusing on deep learning and EHR were published between 2010 and 2018. Despite the common workflow structure appearing in these publications, no trusted and verified software framework exists, forcing researchers to arduously repeat previous work. In this paper, we propose Cardea, an extensible open-source automated machine learning framework encapsulating common prediction problems in the health domain and allows users to build predictive models with their own data. This system relies on two components: Fast Healthcare Interoperability Resources (FHIR) -- a standardized data structure for electronic health systems -- and several AUTOML frameworks for automated feature engineering, model selection, and tuning. We augment these components with an adaptive data assembler and comprehensive data- and model- auditing capabilities. We demonstrate our framework via 5 prediction tasks on MIMIC-III and Kaggle datasets, which highlight Cardea's human competitiveness, flexibility in problem definition, extensive feature generation capability, adaptable automatic data assembler, and its usability

    A ADVOCACIA CRIMINAL E SUA IMPORTÂNCIA À ADMINISTRAÇÃO DA JUSTIÇA E MANUTENÇÃO DO ESTADO DEMOCRÁTICO DE DIREITO

    RESUMO: Desde os tempos antigos a figura do advogado na defesa de acusados se fez necessária, todavia, nos tempos atuais ela é imprescindível, não apenas para a defesa daquele que está sendo acusado da prática de um delito penal, mas também para a manutenção do Estado democrático de direito, dos direitos humanos, dos direitos e garantias fundamentais.No Brasil, onde a violação de tais direitos é constante, seja por parte do Estado quando da seletividade de seu sistema penal e aplicação das penas, bem como por parte da sociedade ao estigmatizar os indivíduos que cometem crimes. É o advogado quem luta para que os direitos destes indivíduos sejam garantidos, para que a dignidade humana seja reconhecida e respeitada, para que a pena não ultrapasse os limites à ela impostos.Palavras-chave: advocacia, justiça, sistema pena

    Get PDF
    The advancement of urbanization in the Philippines changed natural lands into impervious surfaces and aided the contamination of surface runoff and nearby water bodies. Low Impact Development (LID) technologies were introduced as an alternative to conventional drainage systems, specifically permeable pavements. Such technology is beneficial for stormwater runoff reduction, ground infiltration enablement, and stormwater treatment. This research was conducted to investigate the feasibility of permeable pavement for sustainable stormwater management in a university setting, particularly in De La Salle University – Laguna Campus. The Storm Water Management Model (SWMM) was utilized to simulate different rainfall scenarios on selected little to no vegetation regions with increasing permeable pavement area coverage. The findings showed that the LID surface area to subcatchment area (SA/CA) ratio is inversely proportional to the total runoff reduction observed in all rainfall scenarios. The total runoff reached zero when the SA/CA ratio was at least 50%. The permeable pavement was concluded to be effective in surface runoff infiltration, reduction, and storage which is beneficial for long-term stormwater management and flood prevention strategies. The study can be used in future investigations and applications of similar LID technologies

    Essential oils (EOs) are chemical products produced by odoriferous glands from a variety of plants. These essential oils have many health benefits: antiseptic, anti-inflammatory and antimicrobial activities. So due to these medicinal properties, the present study was designed to analyze essential oils of Thymus zygis L. and Thymus willdenowii Boiss. for their chemical composition and biological activities. These two thyme species were collected from the region of Ifrane, Middle Atlas of Morocco. The EO was obtained by hydrodistillation, and the yields were 5.25% for T. zygis and 3.00% for T. willdenowii. The chemical composition of the EOs was analyzed by gas chromatography coupled with mass spectrometry (GC-MS), and the results showed that T. zygis EO is dominated by carvacrol (52.5%), o-cymene (23.14%), and thymol (9.68%), while the EO of T. willdenowii contains germacrene D (16.51%), carvacrol (16.19%), and geranyl acetate (8.35%) as major compounds. The antioxidant activity assessed by Diphenylpicrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays revealed that both EOs have excellent antioxidant activities; by DPPH it resulted in IC50 = 6.13 ± 0.11 for T. zygis and 6.78 ± 0.3 µg/mL for T. willdenowii, while the one by FRAP yielded EC50 = 2.46 ± 0.01 (T. zygis) and 5.17 ± 0.2 (T. willdenowii) µg/mL. The antimicrobial activity of the two essential oils was evaluated against six bacterial strains and five fungal strains by the disk diffusion method to determine the Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC) and Minimum Fungicidal Concentration (MFC). The EOs revealed variable antimicrobial activities against the different tested microbial strains and showed strong antimicrobial activities, even against strains known as multi-resistant to antibiotics (Acinetobacter baumannii) at low concentrations (2 µL/mL). T. zygis EO showed the most powerful activity against all the studied bacteria, while that of T. willdenowii recorded moderate activity when tested against Shigella dysenteriae and Salmonella Typhi. With inhibition diameters that vary between 75 mm and 84 mm for concentrations of 2 µL/mL up to 12 µL/mL, S. aureus was shown to be the most sensitive to T. zygis EO. For the antifungal activity test, T. zygis EO showed the best inhibition diameters compared to T. willdenowii EO. These results showed that T. zygis EO has more powerful antioxidant and antimicrobial activities than T. willdenowii EO, therefore, we deduce that thyme EOs are excellent antioxidants, they have strong antimicrobial properties, and may in the future represent new sources of natural antiseptics that can be used in pharmaceutical and food industry

    Abstract The study was conducted to investigate the effect of CPPU(2-Chloro-4-pyridyl-phenylurea) and NAA (Naphthaleneacetic acid) on the pigments, total phenol, flavonoid and mineral (K+) content in wax apple fruit. CPPU concentrations were 10, 15 and 20ppm (Expt.1) and 6, 12, 18ppm NAA were applied coming after swabbing technique (Expt.2). In Expt.1, the lowest fruit weight, fruit size and chlorophyll content was observed in control treatment. However, the highest fruit weight, fruit size and chlorophyll (SPAD) content was found in 15ppm CPPU. The most effective concentration was 15ppm CPPU for the earlier fruit maturity (color development) compared to other concentrations. Moreover, flavonoid, fructose, inverted sugar, total phenol and K+ were higher in 15ppm CPPU than control, 10 and 20ppm CPPU. In addition, anthocyanin was found increasing trend while developing the fruit maturity represented by color development. In Expt.2, chlorophyll was higher in 15ppm CPPU than control, 6, 18ppm NAA. Furthermore, flavonoid, fructose, inverted sugar, total phenol and K+ content were higher in 12ppm NAA than control, 6 and 18ppm NAA. Besides, the maximum anthocyanin was found in 12ppm NAA. Finally it seemed that 15ppm CPPU and 12ppm NAA were the best concentration for fruit growth and biochemical contents development in wax apple

    Get PDF
    PURPOSE: The Global Burden of Diseases (GBD) Studies have estimated that low back pain is one of the costliest ailments worldwide. Subsequent to GBD publications, leadership of the four largest global spine societies agreed to form SPINE20. This article introduces the concept of SPINE20, the recommendations, and the future of this global advocacy group linked to G20 annual summits. METHODS: The founders of SPINE20 advocacy group coordinated with G20 Saudi Arabia to conduct the SPINE20 summit in 2020. The summit was intended to promote evidence-based recommendations to use the most reliable information from high-level research. Eight areas of importance to mitigate spine disorders were identified through a voting process of the participating societies. Twelve recommendations were discussed and vetted. RESULTS: The areas of immediate concern were "Aging spine," "Future of spine care," "Spinal cord injuries," "Children and adolescent spine," "Spine-related disability," "Spine Educational Standards," "Patient safety," and "Burden on economy." Twelve recommendations were created and endorsed by 31/33 spine societies and 2 journals globally during a vetted process through the SPINE20.org website and during the virtual inaugural meeting November 10-11, 2020 held from the G20 platform. CONCLUSIONS: This is the first time that international spine societies have joined to support actions to mitigate the burden of spine disorders across the globe. SPINE20 seeks to change awareness and treatment of spine pain by supporting local projects that implement value-based practices with healthcare policies that are culturally sensitive based on scientific evidence
