ElectronixTutor: an intelligent tutoring system with multiple learning resources for electronics
No full textBackground: The Office of Naval Research (ONR) organized a STEM Challenge initiative to explore how intelligent tutoring systems (ITSs) can be developed in a reasonable amount of time to help students learn STEM topics. This competitive initiative sponsored four teams that separately developed systems that covered topics in mathematics, electronics, and dynamical systems. After the teams shared their progress at the conclusion of an 18-month period, the ONR decided to fund a joint applied project in the Navy that integrated those systems on the subject matter of electronic circuits. The University of Memphis took the lead in integrating these systems in an intelligent tutoring system called ElectronixTutor. This article describes the architecture of ElectronixTutor, the learning resources that feed into it, and the empirical findings that support the effectiveness of its constituent ITS learning resources. Results: A fully integrated ElectronixTutor was developed that included several intelligent learning resources (AutoTutor, Dragoon, LearnForm, ASSISTments, BEETLE-II) as well as texts and videos. The architecture includes a student model that has (a) a common set of knowledge components on electronic circuits to which individual learning resources contribute and (b) a record of student performance on the knowledge components as well as a set of cognitive and non-cognitive attributes. There is a recommender system that uses the student model to guide the student on a small set of sensible next steps in their training. The individual components of ElectronixTutor have shown learning gains in previous decades of research. Conclusions: The ElectronixTutor system successfully combines multiple empirically based components into one system to teach a STEM topic (electronics) to students. A prototype of this intelligent tutoring system has been developed and is currently being tested. ElectronixTutor is unique in its assembling a group of well-tested intelligent tutoring systems into a single integrated learning environment
Using the Internet to Facilitate Career Choices in Psychology-Related Fields
No full textCareer planning for psychology majors has broadened to include a diverse array of opportunities (e.g., medicine, law, education, government, and military). The Internet has made it possible for students to learn about and quickly obtain information regarding these new career options. This article describes various career resources on the Internet and highlights which websites might be best for students with a clear career direction, as well as those for students who are unclear about what the future holds. The websites described include large sites not affiliated with a college, university, or professional organization. Other websites described are affiliated with a(n) (a) psychology department, (b) department of the federal government, (c) for-profit company or nonprofit organization, (d) professional organization, and (e) online career management site
Complexes of lutein with bovine and caprine caseins and their impact on lutein chemical stability in emulsion systems: Effect of arabinogalactan
No full textLutein is an important xanthophyll carotenoid with many benefits to human health. Factors affecting the application of lutein as a functional ingredient in low-fat dairy-like beverages (pH 6.0–7.0) are not well understood. The interactions of bovine and caprine caseins with hydrophobic lutein were studied using UV/visible spectroscopy as well as fluorescence. Our studies confirmed that the aqueous solubility of lutein is improved after binding with bovine and caprine caseins. The rates of lutein solubilization by the binding to bovine and caprine caseins were as follows: caprine αS1-II-casein 34%, caprine αS1-I-casein 10%, and bovine casein 7% at 100 μM lutein. Fluorescence of the protein was quenched on binding supporting complex formation. The fluorescence experiments showed that the binding involves tryptophan residues and some nonspecific interactions. Scatchard plots of lutein binding to the caseins demonstrated competitive binding between the caseins and their sites of interaction with lutein. Competition experiments suggest that caprine αS1-II casein will bind a larger number of lutein molecules with higher affinity than other caseins. The chemical stability of lutein was largely dependent on casein type and significant increases occurred in the chemical stability of lutein with the following pattern: caprine αS1-II-casein \u3e caprine αS1-I-casein \u3e bovine casein. Addition of arabinogalactan to lutein-enriched emulsions increases the chemical stability of lutein-casein complexes during storage under accelerated photo-oxidation conditions at 25°C. Therefore, caprine αS1-II-casein alone and in combination with arabinogalactan can have important applications in the beverage industry as carrier of this xanthophyll carotenoid (lutein)
Modeling communities in e\u3csup\u3e3\u3c/sup\u3evalue
No full textIncreasingly, communities play an important role in business value models. However, in e value, there seems not to be a suitable construct to model communities. In this paper, we propose an additional concept that can be used for communities, namely the group . We illustrate the use of this concept for understanding a business model in the field of ICT4D (ICT for developing countries). abstract environment
Distance Product of Graphs
Get PDFIn graph theory, different types of product of two graphs have been studied, e.g. Cartesian product, Tensor product, Strong product, etc. Later on, Cartesian product and Tensor product have been generalized by 2-Cartesian product and 2-Tensor product. In this paper, we give one more generalize form, distance product of two graphs. Mainly we discuss the connectedness, bipartiteness and Eulerian property in this product
Study of Pseudo BL–Algebras in View of Left Boolean Lifting Property
Get PDFIn this paper, we define left Boolean lifting property (right Boolean lifting property) LBLP (RBLP) for pseudo BL–algebra which is the property that all Boolean elements can be lifted modulo every left filter (right filter) and next, we study pseudo BL-algebra with LBLP (RBLP). We show that Quasi local, local and hyper Archimedean pseudo BL–algebra that have LBLP (RBLP) has an interesting behavior in direct products. LBLP (RBLP) provides an important representation theorem for semi local and maximal pseudo BL–algebra
Study of Spilled Oil Behavior on the Topsoil Induced by Thermal Diffusion
Get PDFThe fate and transport of oil spilled in soil has long been a focus for experimental and theoretical research in subsurface hydrology. Oil transport in the soil is affected by a large number of physical, chemical and microbial processes; and the properties of the media. This study is a two layer problem containing horizontal oil layer overlying the subsurface topsoil region saturated with oil and water (native fluid). To explain the method by which the convective flow in the oil region affect the transportation of oil, modeling is carried out in two regions (oil and topsoil). The two dimensional, transient oil flow equations for both the regions include thermal and concentration buoyancy effects. The species equations include the effects of energy flux caused by the temperature gradient on the unsteady advective-diffusion equation. The resulting fluid flow, heat and mass transfer processes are discussed numerically with the aid of graphs. The validity of the results obtained is verified by comparison with available results and good agreement is found
Toxic silence
No full textToxic Silence: Race, Black Gender Identity, and Addressing the Violence against Black Transgender Women in Houston contributes to a growing body of transgender scholarship. This book examines the patriarchal and heteronormative frames within the black community and larger American society that advances the toxic masculinity which violently castigates and threatens the collective embodiment of black transgender women in the USA. Such scholarship is needed to shed more light on the transphobic violence and murders against this understudied group. Little is known about the societal and cultural issues and concerns affecting black transgender women and how their gender identity is met with systemic, institutional, and interpersonal roadblocks. During a time period in American history defined by Time Magazine as The Transgender Tipping Point, black transgender women have emerged as social, cultural, and political subjects to advance our understanding of the lives of people who identity as a part of both the black and LGBTQIA communities. In the end, this book calls on the black community and culture to end the toxic silence and act instead as allies who are more accepting and inclusive of differing sexualities and gender identities in an effort to improve the generative power of black solidarity
