SEMI-INTELLIGENT COMPUTER ASSISTED INSTRUCTION MODEL (CAI, CBE (COMPUTER-BASED EDUCATION), CAL (COMPUTER-ASSISTED LEARNING), CBI (COMPUTER-BASED INSTRUCTION))
Creators: name: Baya'a, Nimer Fayez
Publisher: name: American University
Year: 2023

description: Different approaches have controlled the use of computers as an instructional tool. Among those approaches are the traditional Computer Assisted Instruction (CAI) approach; the LOGO philosophy; and the Intelligent Computer Assisted Instruction (ICAI) systems. Each of these approaches has its own strengths and weaknesses. This study introduces a new approach by providing a new model that can be used to construct educational software. The new model, Semi-Intelligent Computer Assisted Instruction, uses some of the strengths of the existing approaches and compromises on others to remedy the more crippling weaknesses. The major goal was to construct more intelligent programs than the traditional ones, while keeping the construction process as less expensive than that of ICAI programs. An example of how a SICAI model would direct the construction of an educational program (teaching how to solve a quadratic equation) was included in this study. The program was written and tested with a sample of fifty users. Then a statistical analysis was performed. The statistical analysis tested the null hypothesis that the program did not improve the ability of its users in solving quadratic equations; also introduced was a method of using a statistical analysis of the program to indicate changes to be done to improve the program. The program improved significantly the performance of its users; most of the objectives set up for the SICAI model were fulfilled. Also the method for analyzing the performance of the program to suggest changes for improving it was suitable and successful.

description: We exploit the critical locus structure on the Quot scheme $\mathrm{Quot}_{\mathbb A^3}(\mathscr O^{\oplus r},n)$, in particular the associated symmetric obstruction theory, in order to define rank $r$ K-theoretic Donaldson-Thomas invariants of the Calabi-Yau $3$-fold $\mathbb A^3$. We compute the associated partition function as a plethystic exponential, proving a conjecture proposed in string theory by Awata-Kanno and Benini-Bonelli-Poggi-Tanzini. A crucial step in the proof is the fact that the invariants do not depend on the equivariant parameters of the framing torus $(\mathbb C^\ast)^r$. Reducing from K-theoretic to cohomological invariants, we compute the corresponding DT invariants, proving a conjecture of Szabo. Reducing further to enumerative DT invariants, we solve the higher rank DT theory of a pair $(X,F)$, where $F$ is an equivariant exceptional vector bundle on a projective toric $3$-fold $X$. Finally, we give a mathematical definition of the chiral elliptic genus studied in physics by Benini-Bonelli-Poggi-Tanzini. This allows us to define elliptic DT invariants of $\mathbb A^3$ in arbitrary rank, and to study their first properties.

description: The quantum partition function at finite temperature requires computing the trace of the imaginary time propagator. For numerical and Monte Carlo calculations, the propagator is usually split into its kinetic and potential parts. A higher order splitting will result in a higher order convergent algorithm. At imaginary time, the kinetic energy propagator is usually the diffusion Greens function. Since diffusion cannot be simulated backward in time, the splitting must maintain the positivity of all intermediate time steps. However, since the trace is invariant under similarity transformations of the propagator, one can use this freedom to "correct" the split propagator to higher order. This use of similarity transforms classically give rises to symplectic corrector algorithms. The split propagator is the symplectic kernel and the similarity transformation is the corrector. This work proves a generalization of the Sheng-Suzuki theorem: no positive time step propagators with only kinetic and potential operators can be corrected beyond second order. Second order forward propagators can have fourth order traces only with the inclusion of an additional commutator. We give detailed derivations of four forward correctable second order propagators and their minimal correctors.

description: We investigate the information that can be gained by including flavour data in fits of the Standard Model Effective Field Theory (SMEFT) with the assumption of Minimal Flavour Violation (MFV), allowing - as initial conditions at the high scale - leading terms in spurionic Yukawas only. Starting therefore from a theory with no tree level flavour changing neutral currents at the scale of new physics, we calculate effects in flavour changing processes at one loop, and the resulting constraints on linear combinations of SMEFT coefficients, consistently parameterising the electroweak parameters and the CKM within the SMEFT. By doing a global fit including electroweak, Higgs and low energy precision measurements among others, we show that flavour observables put strong constraints on previously unconstrained operator directions. The addition of flavour data produces four independent constraints at order TeV or above on otherwise flat directions; reducing to three when complete U(3)^5 flavour symmetry is assumed. Our findings demonstrate that flavour remains a stringent test for models of new physics, even in the most flavourless scenario.

description: In this work, Five laminated composite materials used for manufacturing trans-tibial prosthetic sockets by using vacuum molding technique. The matrix materials of these composites is Blend of (50 wt. % Epoxy and 50 wt. % PMMA), reinforced with perlon layers, fiber glass layers, carbon fiber layers, hybrid (carbon and glass) fiber layers, and hybrid (carbon and glass) layers with micro Silica particles. The tensile properties, max. shear stress, fracture toughness and alternating bending fatigue properties were measured experimentally. The theoretical part of this work deals with calculations of the fatigue ratio, theoretical factor of safety and failure index. The finite element technique (ANSYS-11) is used to analyze and evaluate alternating bending fatigue characteristics by observing the contours distribution of fatigue life, safety factor, equivalent Von Mises stress, total deformation and maximum shear stress.The results show that changing the type of reinforcement and matrix has a great influence on the measured properties: ultimate tensile strength of (Blend with Glass reinforcement) is the highest. The highest maximum shear stress, fracture toughness, fatigue limit, strain energy limit and safety factor is obtained in Blend with Glass composite with (59.42) MPa, (8.45) MPa.m1/2, (62) MPa, (96.66) Joul/mm3 and (9.3), respectively. Reinforcement with perlon gave the lowest values in all measured properties used in this study. (Blend with Glass reinforcement) composite gave optimum experimental, numerical and theoretical results which make it the best candidate to improve the fatigue characteristics of trans-tibial prosthetic socket
CHANGES IN SELF-CONCEPT OF ACADEMICALLY GIFTED STUDENTS FOLLOWING A SELF-CONTAINED PROGRAM EXPERIENCE (COUNSELING)
Creators: name: Butta, Charles Gregory
Publisher: name: American University
Year: 2023

description: The purpose of this study was to investigate changes in self-concept of gifted males and females, ages 7 through 13 years, as a result of participation in two different self-contained programs for the gifted. This study examined the influence of program type, sex, and age on the self-concept of gifted and talented students enrolled in self-contained academic programs. The sample consisted of 107 gifted children from Washington, D.C., metropolitan school systems. They were identified through various standardized intelligence tests and other measures. Some of the private school nominees were not given standardized intelligence tests, but were nominated for program participation by their teachers' personal evaluation as being academically "exceptional." Self-concept change was measured by the Piers-Harris Children's Self-Concept Scale (Piers, 1969). Data obtained from each subject were compiled in a computerized data base and analyzed with the use of the Statistical Package for the Social Sciences (SPSS). The raw data were subjected to a 2 x 2 x 2 analysis of variance procedure utilizing a fixed-effects model. This analysis yields F ratios needed to test the seven hypotheses specified. Level of significance was set at .05. The data revealed that female students in both self-contained programs gained an average of 3.49 points on their Piers-Harris gain score. A significant main effect due to sex was found. Females consistently outgained their male counterparts in self-concept gain scores for both programs. When differences between group means of self-concept scores were examined, it was found that females, regardless of program age, obtained significantly greater gains in self-concept scores than did their gifted male peers. No significant differences (at .05) in self-concept were found to exist as a result of program type and age. No significant interactions among program, sex, and age were found. Further, a general trend was observed in the direction of increasing self-concept scored for all groups of gifted students who participated in this study. The implications of these results are discussed with respect to roles of special teachers of gifted, counselors, administrators, parents, and gifted peers.

description: Entanglement generation and preservation is a key task in quantum information processing, and a variety of protocols exist to entangle remote qubits via measurement of their spontaneous emission. We here propose feedback methods, based on monitoring the fluorescence of two qubits and using only local pi-pulses for control, to increase the yield and/or lifetime of entangled two-qubit states. Specifically, we describe a protocol based on photodetection of spontaneous emission (i.e. using quantum jump trajectories) which allows for entanglement preservation via measurement undoing, creating a limit cycle around a Bell states. We then demonstrate that a similar modification can be made to a recent feedback scheme based on homodyne measurement (i.e. using diffusive quantum trajectories), [L. S. Martin and K. B. Whaley, arXiv:1912.00067] in order to increase the lifetime of the entanglement it creates. Our schemes are most effective for high measurement efficiencies, and the impact of less-than-ideal measurement efficiency is quantified. The method we describe here combines proven techniques in a novel way, complementing existing protocols, and offering a pathway towards generating and protecting entangled states so that they may be used in various applications on demand.

description: Telephone interviews have become a popular method for conducting attitudinal surveys and are now commonly substituted for personal interviews. Although there is a growing body of literature comparing the two methods, there is very little research which compares the two methods with respect to trend data. The problem at hand relates to a specific body of trend data collected annually through personal interviews over a 15 year period. Those responsible for the research needed to answer three questions. First, what are the relative advantages and disadvantages of the telephone and personal interview methods? Second, what is the best way to adapt questions previously designed for and asked in personal interviews for use in telephone studies. Third, can subsequent trend data be collected through telephone interviews?; Two simultaneous national studies were conducted in the spring of 1981--one used personal interviews while the second used telephone interviews. In terms of the relative advantages/disadvantages of the two methods, both techniques were compared on 23 factors. The results indicate that the two methods are comparable with respect to nine factors, telephone surveys have the advantage on seven factors, and personal interviews have the advantage with respect to seven factors. For two of four factors generally considered very important in any study--cost and researcher control--telephone surveys have a clear advantage over personal interview surveys. With respect to the other two important factors, sample coverage and response rates, the two methods are rated equally. In terms of adapting personal interview questions to the telephone, it is shown that there are no insurmountable problems for any of the eight question types tested. The question types include: open-end, visual six point scale, visual four point scale, visual three point scale, visual three part statement, rank order, short answer same context, and short answer different context. Finally, it is concluded that although there is a great deal of similarity between the two methods, it is not acceptable to report trend data across the two different survey methods. Rather, it is suggested that separate trend lines should be established in each survey mode.

THE NEEDS OF A SAMPLE OF HIGH SCHOOL STUDENTS IN THE PRINCE WILLIAM COUNTY (VIRGINIA) SCHOOL SYSTEM FOR SELECTED GUIDANCE SERVICES
Creators: name: Eadie, Douglas Browning
Publisher: name: American University
Year: 2023

description: The purpose of this study was to ascertain the needs of a sample of high school students in the Prince William County School System (PWCSS) for 40 selected guidance services, as assessed through the Guidance Services Inventory (GSI), and to draw implications from the findings regarding the need for modification and/or development of the program of guidance services in the PWCSS. This study was descriptive in nature and utilized the inventory-survey approach. Data were elicited through the GSI, an instrument developed specifically by the researcher for this study. The GSI presents 40 guidance services arranged, according to generic type, into five categories. Respondents were asked to express the "extent of need" that they had felt for each of the 40 services while in high school by selecting one of five response alternatives (None, Weak, Medium, Strong, and Very Strong). Twelfth-grade students, seniors (N = 1,282) in all six PWCSS high schools comprised the study sample. These students completed the GSI near the end of their senior year. Responses were studied for the total sample and by respondents' gender, school of attendance, and post-high school plans to determine the extent of need for the 40 guidance services. Study findings are summarized as follows: (1) Respondents expressed some need, at least, for all 40 services. (2) Respondents expressed medium to strong need for 16 of the 40 services; overall, the expressed need was weak to medium. (3) Services related to educational and occupational planning were most needed; personal-social counseling services were least needed. (4) The needs of males and females did not differ notably. (5) Among college-bound students, the strongest need was for college-related services; otherwise, the needs of college-bound and non-college-bound students did not differ notably. (6) The needs of students in the six PWCSS high schools did not differ notably. Findings seemed to support the conclusion that the guidance program in the PWCSS should provide a comprehensive set of services that need not be differentiated on the basis of student gender or high school attended.

description: The University of British Columbia Food Systems Project (UBCFSP) is a community-based action research project coordinated by the Faculty of Land and Food Systems (LFS) and the UBC Social Ecological Economic Development Studies (SEEDS) Program. Since 2001, students, faculty, and campus food staff have been collaborating on food system projects to further campus sustainability. Our project was based on the creation of an engaging introductory activity to be used in an upcoming lecture series, Lenses of Sustainability, for a lecture focusing primarily on local food. Methods included a literature review on the UBC food system, the meaning of local food, and methods of participatory learning. Through our research we found the power of storytelling to be an effective means of introducing local food. We therefore conducted interviews with UBC faculty members to gather stories on the latter, intending to integrate their food systems experiences into a multimedia introductory presentation. To facilitate this interactive format, we are recommending that the lecture be held in the Centre for Interactive Research for Sustainability (CIRS) BC Hydro Theatre, which is a flexible learning space equipped with advanced visual and audio equipment. Furthermore, we developed a preregistration questionnaire with the intention that responses be shared during the lecture by way of said audio-visual equipment as a means of tailoring lecture topics and/or proposed engagement activities to the group in question. This is intended to promote sharing of individuals’ experiences and garner an open forum-type learning environment. In addition, we have developed a list of potential panelists from numerous faculties that could be asked to participate in the lecture to provide their personal lenses on sustainability, thus encouraging cross-faculty conversations on food sustainability. Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community. The reader should bear in mind that this is a student project/report and is not an official document of UBC.

description: The mapping of the Wigner distribution function (WDF) for a given bound-state onto a semiclassical distribution function (SDF) satisfying the Liouville equation introduced previously by us is applied to the ground state of the Morse oscillator. Here we give results showing that the SDF gets closer to the corresponding WDF as the number of levels of the Morse oscillator increases. We find that for a Morse oscillator with one level only, the agreement between the WDF and the mapped SDF is very poor but for a Morse oscillator of ten levels it becomes satisfactory.

description: How do late type spiral galaxies form within the context of a CDM cosmology? We contrast N-body, smoothed particle hydrodynamical simulations of galaxy formation which employ two different supernova feedback mechanisms. Observed mass and metallicity distributions of the stellar halos of the Milky Way and M31 provide constraints on these models. A strong feedback model, incorporating an adiabatic phase in star burst regions, better reproduces these observational properties than our comparative thermal feedback model. This demonstrates the importance of energy feedback in regulating star formation in small systems, which collapse at early epochs, in the evolution of late type disk galaxies.

The tensile and fatigue properties were measured experimentally. The theoretical part of this work deals with calculations of the fatigue ratio and theoretical factor of safety. The finite element technique (ANSYS-11) is used to analyze and evaluate fatigue characteristics. This was done by constructing five models for the socket which were treated as three-dimensional structure composite materials. The results show that changing the type of reinforcement has a great influence on the measured properties. (Epoxy + Carbon reinforcement) composites gave optimum experimental, numerical and theoretical results which make them the best candidate to improve the fatigue characteristics of trans-tibial prosthetic socket.

description: One of the major areas of interest has been the effect of radiation on DNA since these effects have been in general successfully correlated to the radiation-induced lethality, mutagenesis, and possibly carcinogenesis. The chemistry of pyrimidine is represented by thymine (T) one of the four DNA bases and used in this work as a model component. Deoxyribose, dR, was used as a model for the reaction of the sugar in DNA. In this work the reactions of: d(')R + d(')R (--->) dR-dR. d(')R + (')T-OH (--->) dR-T-OH. d(')R + (')Phe-OH (--->) dR-Phe-OH. were investigated for possible crosslinks which would represent a model for intra-DNA and DNA-protein crosslinks. These reactions have not been investigated before. The products were isolated and identified using capillary gas chromatography, and capillary gas chromatography-mass spectrometry. In addition, the yields of crosslinks between thymine deoxyribose and phenylalanine deoxyribose and deoxyribose deoxyribose were determined by gas chromatography. Mechanisms of their formation are discussed in detail. As a means of standardizing the irradiations of DNA solutions, special radiochromic dye solutions in several organic solvents have been investigated as standard dosimeters in this work. These radiation sensors are well-behaved chromophoric systems, based on the formation of highly colored carbonium ions from leuco triphenyl- methane dyes (e.g., pararosaniline leucocyanide or some of its analogs). (NH(,2)C(,6)H(,4))(,3)C-CN -- (--->) NH(,2)C(,6)H(,4)=C=(NH(,2)C(,6)H(,4))(,2) + C(')N. The great advantage of developing and using these standard solutions for the dosimetry is that their radiation absorption cross-sections match closely those of the DNA solutions, thus leading to highly accurate radiation absorbed dose. A choice has been made in terms of the most accurate chemical dosimeter for the purpose of this research, by examining the uncertainty probabilities of meas- uring radiation chemical yields (G-value) of radiolytic dye formation, as well as linear molar absorption coefficients ((epsilon)) of the radiation-induced species. After establishing the G-values of dye formation using gamma radiation from a ('60)Co source, kinetics studies have been made for this dye formation in selected solvents in terms of first-order rate constants.

description: This is a major issue. Therefore Blood Flow in Brain is always vital. It makes little sense to buy a Blood Flow in Brain in this case. I'm a Blood Flow in Brain scientist. That is a free lesson. I guess the Blood Flow in Brain example is very good. It is possible to overlook that these are the factors you should know as that relates to Blood Flow in Brain. Blood Flow in Brain is a magnificent treasure. However, like my helper says, "Work smarter not harder." https://knowthepills.com/ways-to-increase-blood-flow-to-the-brain/
THE ROLE OF SUGAR IN RADIATION-INDUCED CROSSLINKS IN DNA
Creators: name: Farahani, Mahnaz

description: One of the major areas of interest has been the effect of radiation on DNA since these effects have been in general successfully correlated to the radiation-induced lethality, mutagenesis, and possibly carcinogenesis. The chemistry of pyrimidine is represented by thymine (T) one of the four DNA bases and used in this work as a model component. Deoxyribose, dR, was used as a model for the reaction of the sugar in DNA. In this work the reactions of: d(')R + d(')R (--->) dR-dR. d(')R + (')T-OH (--->) dR-T-OH. d(')R + (')Phe-OH (--->) dR-Phe-OH. were investigated for possible crosslinks which would represent a model for intra-DNA and DNA-protein crosslinks. These reactions have not been investigated before. The products were isolated and identified using capillary gas chromatography, and capillary gas chromatography-mass spectrometry.

description: By establishing a digital repository for the Feinberg School of Medicine (FSM) (Northwestern University, Chicago campus), we anticipate gaining the ability to create, share, and preserve attractive, functional, and citable digital collections and exhibits. Galter Health Sciences Library did not have a repository as of November 2014. In just a few months we formed a small team that was charged at looking to select the most suitable open source platform for our digital repository software. We followed the National Library of Medicine master evaluation criteria by looking at various factors that included: functionality, scalability, extensibility, interoperability, ease of deployment, system security, system,
physical environment, platform support, demonstrated successful deployments, system
support, strength of development community, stability of development organization, and strength of technology roadmap for the future. These factors are important for our case considering the desire to connect the digital repository with platforms that produce VIVO compatible structured linked data. VIVO is a linked data platform that serves as a researchers' hub and which provides the names of researchers from academic institutions along with their research output, affiliation, research overview, service, background, researcher's identities, teaching, and much more.

THE HETEROGENEITY OF BULIMIA

description: This study examined subgroups of bulimics based on the method of weight restriction used. Sixty Caucasian women (45 normal-weight bulimics and 15 normal-weight controls) served as subjects. The bulimic subjects were 15 fasters, 15 vomiters, and 15 laxative abusers. They all fulfilled an operational definition of the diagnostic criteria for bulimia found in the Diagnostic and Statistical Manual of Mental Disorders (DSM III; American Psychiatric Association, 1980). All subjects were administered the Brief Symptom Inventory, the Beck Depression Inventory, and the Personal Attributes Questionnaire, the Attitudes Toward Women Scale, the State Trait Anxiety Scale-A Trait, the Reid-Ware Internal External Scale, the Rosenberg Self-Esteem Scale, and a body image assessment. Each subject was also asked to complete a structured interview. The bulimic women contrasted significantly with the controls in several areas. For instance, the bulimic subjects evidenced significantly more psychological distress. They were more depressed and anxious, had greater interpersonal sensitivity and lower self-esteem, experienced more difficulty with self-control, and had a poorer body image. Among the bulimic groups there were also major differences. The laxative abusers had significantly more overall distress than the vomiters and fasters. They were more depressed, anxious, and hostile. The vomiting and fasting groups responded similarly on many of the variables. These results suggest qualitative differences among bulimics and provide empirical support for the consideration of subgroups in future diagnostic criteria for bulimia.

description: We reevaluate the electric dipole moment (EDM) of charged leptons in the standard model using hadron effective models. We find unexpectedly large EDM generated by the hadron level long-distance effect, $d_e = { 5.8 \times 10^{-40} }$, $d_μ= { 1.4 \times 10^{-38}}$, and $d_τ= { -7.3 \times 10^{-38} }$ ecm, with an error bar of 70\%, exceeding the conventionally known four-loop level elementary contribution by several orders of magnitude.
