Elementary Science Teachers Perceived Self-Efficacy: A Correlational Study between Teachers with Content and Non-Content Major Degrees in New Jersey

This predictive, correlational study examines the relationship between undergraduate degree type, methods courses taken in undergraduate school, and the number of years teaching the same grade level and elementary science teachers’ perceived self-efficacy. In this non-experimental study, participants submitted their online responses to the 25-item survey, Science Teaching Efficacy Belief Instrument (STEBI-A), and their demographic information via Google Forms. The researcher used multiple regression to analyze participants’ anonymous responses. In using a multiple linear regression analysis, the researcher examined the results of the STEBI-A to determine how accurately an elementary science teachers’ perceived self-efficacy is predicted by the predictor variable of type of undergraduate degree earned, years of teaching the same grade for elementary science teachers. The type of degree and science method courses variables did not display an ability to predict elementary science teacher self-efficacy. The participants for the study came from a snowball sample of elementary school teachers located in New Jersey during the summer semester of the 2022-2023 school year with N = 138 with a minimum of N = 71. The study revealed a statistically significant relationship between self-efficacy and the number of years of teaching the same grade level; however, undergraduate degree earned, and science methods courses did not show a statistically significant contribution to the overall model. Based on the results of this study a multiple regression study with degree type and subject matter professional development exposure as predictive variables is recommended

Enterprise Resource Planning and Organizational Knowledge: Patterns of Convergence and Divergence

This paper reports on a qualitative research study to investigate how enterprise resource planning systems impact organizational knowledge. Cognitive mapping methodology was used to capture and analyze the perspectives of senior managers from the IT and user organizations of a major corporation. The results indicate that ERP systems produce effects that make business knowledge become more focused or convergent from the perspective of the organization and more wide-ranging or divergent from the perspective of the individual. Other important effects include changes to the organization\u27s core competencies and changes in the risk profile regarding the loss of organizational knowledge. The research contributes to the knowledge-based view of enterprise systems

Quantum Group Covariance and the Braided Structure of Deformed Oscillators

The connection between braided Hopf algebra structure and the quantum group covariance of deformed oscillators is constructed explicitly. In this context we provide deformations of the Hopf algebra of functions on SU(1,1). Quantum subgroups and their representations are also discussed.Comment: 12 pages, to be published in JM

Braided Oscillators

The braided Hopf algebra structure of the generalized oscillator is investigated. Using the solutions two types of braided Fibonacci oscillators are introduced. This leads to two types of braided Biedenharn-Macfarlane oscillators.Comment: 12 pages, latex, some references added, published versio

Health promotion interventions can be improved using methods from behavioural economics to identify and target specific decision-making biases at the individual level. In this context, prospect theory provides a suitable framework within which decision-making processes can be operationalised. Focusing on a trade-off between health outcomes and behaviour change incurred by chronic disease management (lifestyle change, or ‘self-management’), we are the first to measure the risk attitudes and quantify the full utility function under prospect theory of a patient population. We conducted a series of hypothetical elicitations over health outcomes associated with different self-management behaviours from a population of individuals with or without ‘manageable’ chronic disease (n = 120). We observed risk aversion in both the gain and the loss domains, as well as significant loss aversion. There seems to be an age effect on risk attitudes in this context, with younger people being on average less risk averse than older people. Our work addresses a need to better understand these decision-making processes, so that behaviour change interventions tailored to specific patient populations can be improved

Designing an information system for updating land records in Bangladesh: action design ethnographic research (ADER)

Open Access. This article is distributed under the terms of the Creative Commons Attribution License which permits any use, distribution, and reproduction in any medium, provided the original author(s) and the source are credited.This article has been made available through the Brunel Open Access Publishing Fund.Information Systems (IS) has developed through adapting, generating and applying diverse methodologies, methods, and techniques from reference disciplines. Further, Action Design Research (ADR) has recently developed as a broad research method that focuses on designing and redesigning IT and IS in organizational contexts. This paper reflects on applying ADR in a complex organizational context in a developing country. It shows that ADR requires additional lens for designing IS in such a complex organizational context. Through conducting ADR, it is seen that an ethnographic framework has potential complementarities for understanding complex contexts thereby enhancing the ADR processes. This paper argues that conducting ADR with an ethnographic approach enhances design of IS and organizational contexts. Finally, this paper aims presents a broader methodological framework, Action Design Ethnographic Research (ADER), for designing artefacts as well as IS. This is illustrated through the case of a land records updating service in Bangladesh

Symmetric Skyrmions

We present candidates for the global minimum energy solitons of charge one to nine in the Skyrme model, generated using sophisticated numerical algorithms. Assuming the Skyrme model accurately represents the low energy limit of QCD, these configurations correspond to the classical nuclear ground states of the light elements. The solitons found are particularly symmetric, for example, the charge seven skyrmion has icosahedral symmetry, and the shapes are shown to fit a remarkable sequence defined by a geometric energy minimization (GEM) rule. We also calculate the energies and sizes to within at least a few percent accuracy. These calculations provide the basis for a future investigation of the low energy vibrational modes of skyrmions and hence the possibility of testing the Skyrme model against experiment.Comment: latex, 9 pages, 1 figure (fig1.gif

Instanton vibrations of the 3-Skyrmion

The Atiyah-Drinfeld-Hitchin-Manin matrix corresponding to a tetrahedrally symmetric 3-instanton is calculated. Some small variations of the matrix correspond to vibrations of the instanton-generated 3-Skyrmion. These vibrations are decomposed under tetrahedral symmetry and this decomposition is compared to previous knowledge of the 3-Skyrmion vibration spectrum.Comment: 10 pages, LaTeX, no figures, PRD version with longer introduction and minor change
