description: Non-ideal MHD effects have been shown recently as a robust mechanism of averting the magnetic braking "catastrophe" and promoting protostellar disc formation. However, the magnetic diffusivities that determine the efficiency of non-ideal MHD effects are highly sensitive to microphysics. We carry out non-ideal MHD simulations to explore the role of microphysics on disc formation and the interplay between ambipolar diffusion (AD) and Hall effect during the protostellar collapse. We find that removing the smallest grain population ($\lesssim$10 nm) from the standard MRN size distribution is sufficient for enabling disc formation. Further varying the grain sizes can result in either a Hall-dominated or an AD-dominated collapse; both form discs of tens of AU in size regardless of the magnetic field polarity. The direction of disc rotation is bimodal in the Hall dominated collapse but unimodal in the AD-dominated collapse. We also find that AD and Hall effect can operate either with or against each other in both radial and azimuthal directions, yet the combined effect of AD and Hall is to move the magnetic field radially outward relative to the infalling envelope matter. In addition, microphysics and magnetic field polarity can leave profound imprints both on observables (e.g., outflow morphology, disc to stellar mass ratio) and on the magnetic field characteristics of protoplanetary discs. Including Hall effect relaxes the requirements on microphysics for disc formation, so that prestellar cores with cosmic-ray ionization rate of $\lesssim$2--3$\times10^{-16}$ s$^{-1}$ can still form small discs of $\lesssim$10 AU radius. We conclude that disc formation should be relatively common for typical prestellar core conditions, and that microphysics in the protostellar envelope is essential to not only disc formation, but also protoplanetary disc evolution.

description: Observations of distant supernovae indicate that the Universe is now in a phase of accelerated expansion the physical cause of which is a mystery. Formally, this requires the inclusion of a term acting as a negative pressure in the equations of cosmic expansion, accounting for about 75 per cent of the total energy density in the Universe. The simplest option for this "dark energy" corresponds to a cosmological constant, perhaps related to the quantum vacuum energy. Physically viable alternatives invoke either the presence of a scalar field with an evolving equation of state, or extensions of general relativity involving higher-order curvature terms or extra dimensions. Although they produce similar expansion rates, different models predict measurable differences in the growth rate of large-scale structure with cosmic time. A fingerprint of this growth is provided by coherent galaxy motions, which introduce a radial anisotropy in the clustering pattern reconstructed by galaxy redshift surveys. Here we report a measurement of this effect at a redshift of 0.8. Using a new survey of more than 10,000 faint galaxies, we measure the anisotropy parameter b = 0.70 +/- 0.26, which corresponds to a growth rate of structure at that time of f = 0.91 +/- 0.36. This is consistent with the standard cosmological-constant model with low matter density and flat geometry, although the error bars are still too large to distinguish among alternative origins for the accelerated expansion. This could be achieved with a further factor-of-ten increase in the sampled volume at similar redshift.

Generative Design Software Development Process for Architecture

subject: FOS: Civil engineering

description: The existing design method of using traditional CAD (Computer Aided Design) software to explore architectural design alternatives is time-consuming and tedious. Generative Design ( hereinafter called the GD ) software is a potential solution that can streamline the design process and provide creative design alternatives for architects. However, current GD software is not widely accepted by architects because they are either difficult to use, or their generated results don't meet architect’s needs because the solutions it generates don’t always meet design criteria. This situation reflects a more fundamental reason that limits the promotion of GD software which the industry lacks a software development process that could guide developers to develop valuable GD software for architects.Therefore, in this thesis, I propose a development process to fill the gap. The process consists of four major steps and it integrates the necessary architectural design knowledge and programming resources to follow and reference. To demonstrate the feasibility of the process, I developed a GD software for a basement parking layout design task. Based on the generative method of variational modeling with optimization, this tool can generate a variety of valuablebasement parking layouts in a very limited amount of time. According to the software test result, the generated solution reaches about 86.95% accuracy but reduces 36% modeling time when architects use it to reproduce an existing basement parking layout. The GD software developed under the guidance of the process proved to be valuable.
Connecting to nature : how nature facilitates wellness
Creators: name: Nicol, Valerie J.

description: This study posed the question: How does connecting to nature facilitate welless. The Critical Incident Technique (Flanagan, 1954) was employed to develop a reasonably comprehensive scheme of categories that describe what, in connecting to nature, facilitates wellness. Twelve participants were interviewed which resulted in the elicitation of 80 critical incidents. These incidents were organized into seven categories wliich were tested for soundness and trustworthiness. The categories indicate that wellness can be facilitated by: observation of the natural environment, observation of animals, activities in nature, overcoming a challenge in nature, performing a ceremony in nature, expressing feelings in nature, and extraordinary experiences in nature. A preliminary examination of the outcomes described in the 80 critical incidents suggests that empowennent, relaxation, release, perspective and connection can result from making a connection to nature. A preliminary examination of what led up to the critical incidents was also conducted and revealed that emotional turmoil, decision-making, engaging in outdoor activities and work are possible precursors to the facilitation of wellness in nature. The findings of this study are presented in a reasonably comprehensive scheme of categories that describe how nature can facilitate wellness. These findings contribute to the field of counselhng psychology by providing an exploratory examination of an area previously overlooked, and by indicating potential implications for both research and practice.

description: Ba{[Gax,Tax]Ti(1-2x)}O3 ceramics with x equal to 0, 0.0025, 0.005, 0.01, 0.025 and 0.05 have been prepared by conventional solid-state reaction. Structural and dielectric characterization have been performed to investigate the effect of dipole-pair substitution concentration on the macroscopic dielectric properties. Ba{[Gax,Tax]Ti(1-2x)}O3 evolves from a classic ferroelectric to a diffuse phase transition (DPT) as x increases. Ba{[Gax,Tax]Ti(1-2x)}O3 for x > or = 0.01 possesses diffuseness parameters comparable to Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) and recently reported (Ba0.97Pr0.03)(Ti0.9425Ce0.05)O3 (BPTC), yet it lacks the frequency and temperature dependence of Tm necessary to be a strictly defined relaxor ferroelectric. Additionally, Ba{[Ga0.05,Ta0.05]Ti0.9}O3 possesses a relative permittivity, εr, of 700+/-16% and dissipation factor less than 0.05 at 10 kHz within the temperature range [-75°C, 120°C]. In comparison to BaTiO3, Ba{[Gax,Tax]Ti(1-2x)}O3 possesses enhanced electrical resistivity at and above room temperature. In-situ XRD, including Rietveld refinement, have been performed to determine the lattice parameter, coefficient of thermal expansion and phase transition temperature (Tc) of each composition within the temperature range [RT, 1000°C], thus linking the dielectric properties with the materials structure. These studies have been corroborated by temperature dependent Raman spectroscopy to compare the Tc determined by electrical and structural characterization. The properties of Ba{[Gax,Tax]Ti(1-2x)}O3 are discussed in context with available models that describe donor and acceptor dopants spatially separated in the parent matrix, inter-relating lattice parameter, Curie temperature, and other material properties
Quasinormal frequencies of D-dimensional Schwarzschild black holes: evaluation via continued fraction method

Year: 2006
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We adopt Leaver's method to determine quasi normal frequencies of the Schwarzschild black hole in higher (D >= 10) dimensions. In D-dimensional Schwarzschild metric, when D increases, more and more singularities, spaced uniformly on the unit circle |r|=1, approach the horizon at r = r_h = 1. Thus, a solution satisfying the outgoing wave boundary condition at the horizon must be continued to some mid point and only then the continued fraction condition can be applied. This prescription is general and applies to all cases for which, due to regular singularities on the way from the point of interest to the irregular singularity, Leaver's method in its original setting breaks down. We illustrate the method calculating gravitational vector and tensor quasinormal frequencies of the Schwarzschild black hole in D=11 and D=10 dimensions. We also give the details for the D=9 case, considered in gr-qc/0511064.

description: The chiral quark model gives a reasonably good description of many low-energy observables by incorporating the effective degrees carried by the constituent quarks and Goldstone bosons. We calculate the decuplet to octet transition magnetic moments and the decay widths of several excited hyperons using this model. The various radiative decay widths from the chiral quark roughly agree with experimental data including the recent JLAB measurement.
The Initial Properties of Young Star Clusters in M83

description: The initial sizes and masses of massive star clusters provide information about the cluster formation process and also determine how cluster populations are modified and destroyed, which have implications for using clusters as tracers of galaxy assembly. Young massive cluster populations are often assumed to be unchanged since cluster formation, and therefore their distribution of masses and radii are used as the initial values. However, the first few hundred million years of cluster evolution does change both cluster mass and cluster radius, through both internal and external processes. In this paper, we use a large suite of $N$-body cluster simulations in an appropriate tidal field to determine the best initial mass and initial size distributions of young clusters in the nearby galaxy M83. We find that the initial masses follow a power-law distribution with a slope of -2.7 $\pm$ 0.4, and the half-mass radii follow a log-normal distribution with a mean of 2.57 $\pm$ 0.04 pc and a dispersion of 1.59 $\pm$ 0.01 pc. The corresponding initial projected half-light radius function has a mean of 2.7 $\pm$ 0.3 pc and a dispersion of 1.7 $\pm$ 0.2 pc. The evolution of the initial mass and size distribution functions are consistent with mass loss and expansion due to stellar evolution, independent of the external tidal field and the cluster's initial density profile. Observed cluster sizes and masses should not be used as the initial values, even when clusters are only a few hundred million years old.

Year: 2021
Subjects: subject: 120199 Architecture not elsewhere classified
subject: FOS: Civil engineering

description: This research presents Hybrid Embroidery, a system for interactive fabrication that leverages the potential of computation to broaden the possibilities of the embroidery craft. Combining traditional crafting techniques of embroidery, computational design methods, computer vision, and computer numerical control (CNC), the research shows how this framework elicits a variety of innovative fabrication experiences that emphasize open-ended exploration, improvisation, and play. Interacting with the system's algorithms in a conversational, turn-based fashion, users create generative embroidery stitching paths that result in unique embroidery pieces. Each embroidered piece acts as a module of the bigger picture in the game of exquisite corpse based on the inherent communal nature in textile crafting. Hybrid Embroidery thus offers an example of how computational methods may enrich crafts and other creative practices. Further, the research highlights implications for supporting creative exploration through real-time and direct manipulation of materials and close human-machine interaction. Through Hybrid Embroidery, this thesis documents results and challenges to reflect on how to reposition embroidery with a tradition of collectivity in traditional crafting.
Needs assessment : a survey of Western Canada’s program administrators’ perspectives of the role of EAPs in the workplace
Creators: name: Rodriguez, Javier
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to assess the needs of employees in regard to their Employee Assistance Programs (EAPs) according to the program administrators' perspective. Information was collected from 62 program administrators within 54 organizations across Western Canada using a self-administered questionnaire. The 132-item questionnaire included demographic information and ten sections devoted to elicit administrators' perspectives on employees' needs (prevalence of problems, severity of problems, barriers to EAP utilization, program awareness, prevention programs, training and information for supervisors and union representatives, personal problems and the workplace, the role of the EAP in the workplace, the role of the EAP provider in the workplace, and a general overview). Results show that administrators perceive a greater prevalence and severity of problems than EAP utilization. There is also a perceived large EAP support among its participants (i.e., senior management, supervisors, union representatives, employees) as a relevant means to address employees' and their family members' problems. The outcome of the study indicates as well that personal and family members' problems affect employees and the workplace in a very significant way. Administrators believe that the EAP is a very important resource to deal with such problems. Additionally, results point out the important need for providing employees with information and prevention programs that may equip them with particular resources to address their problems before they affect them at work.
Geometrical formulation for adjoint-symmetries of partial differential equations

description: A geometrical formulation for adjoint-symmetries as 1-forms is studied for general partial differential equations (PDEs), which provides a dual counterpart of the geometrical meaning of symmetries as tangent vector fields on the solution space of a PDE. Two applications of this formulation are presented. Additionally, for systems of evolution equations, adjoint-symmetries are shown to have another geometrical formulation given by 1-forms that are invariant under the flow generated by the system on the solution space. This result is generalized to systems of evolution equations with spatial constraints, where adjoint-symmetry 1-forms are shown to be invariant up to a functional multiplier of a normal 1-form associated to the constraint equations. All of the results are applicable to the PDE systems of interest in applied mathematics and mathematical physics.

Kinetically Dominated FRII Radio Sources

Publisher: name: arXiv
Year: 2006

subject: FOS: Physical sciences

description: The existence of FR II objects that are kinetically dominated, the jet kinetic luminosity, $Q$, is larger than the total thermal luminosity (IR to X-ray) of the accretion flow, $L_{bol}$, is of profound theoretical interest. Such objects are not expected in most theoretical models of the central engine of radio loud AGN. Thus, establishing such a class of objects is an important diagnostic for filtering through the myriad of theoretical possibilities. This paper attempts to establish a class of quasars that have existed in a state of kinetic dominance, $R(t)\equiv Q(t)/L_{bol}(t)>1$, at some epoch, $t$. It is argued that the 10 quasars in this article with a long term time average $Q(t)$, $\bar{Q}$, that exceed $L_{Edd}$ are likely to have satisfied the condition $R(t)>1$ either presently or in the past based on the rarity of $L_{bol}>L_{Edd}$ quasars. Finally, the existence of these sources is discussed in the context of the theory of the central engine.

description: This thesis presents what I feel is a practical solution to a problem with interpretation at American railroad museums. In spite of a long and well documented history, African-American railroaders are often given short shrift at railroad museums, and not just enthusiast organized and administered museums but large, seemingly professional institutions. Section I of this thesis will review railroad museums, their interpretation and their visitors, as well as the broader railroad enthusiasts' community and how this community impacts railroad museum interpretation. I will use the B&O Railroad Museum in Baltimore, MD as a case study. Section II will discuss African-American railroad history with a focus on Pullman porters, their union the Brotherhood of Sleeping Car Porters and the contributions porters and union president A. Phillip Randolph made to the civil rights struggle. Section III is the performance piece, with recommendation for props, costumes and suggestions for an appropriate venue.

description: Single strand DNA binding proteins, or SSB's, play a crucial part in DNA replication, recombination, and repair for many organisms. The gene 32 protein of bacteriophage T4 (gp32) is well known for its model behavior as a classical SSB. Limited proteolysis of gp32 affords three consecutive domains that are functionally unique--a positively-charged N-domain, a core domain where single-stranded DNA (ssDNA) is bound, and a negatively-charged C-domain (CTD). The C-terminal domain influences heterotypic protein interaction and inhibits gp32's ability to destabilize double-stranded DNA (dsDNA). The C-domain is proposed to weakly bind to the core domain and compete with free ssDNA for binding. In occupying the ssDNA binding region of the core domain, CTD is thought to act as a DNA mimic. This behavior comes from core domain-DNA binding being largely charge dependent (electrostatic interactions). The goal of this investigation is to determine whether the C-domain serves as an internal ssDNA mimic and electrostatic shield by interacting with the core-domain binding cleft. We have overexpressed and purified slightly lengthened C-domain, and employed a modified zero-length cross-linking protocol to selectively attach CTD to core domain. The reaction resulted in the appearance of core + CTD bands on SDS-polyacrylamide gels. Addition of ssDNA or high salt levels during cross-linking created a competitive binding assay, both of which inhibited cross-linked complex formation. We also demonstrated that cross-linked products reflect the native binding position for the C-domain, which supports our current model, where binding of ssDNA and C-domain to the core-domain is mutually exclusive.

description: The World Wide Web Consortium defines a Web Service as a software system designed to support interoperable machine-to-machine interaction over a network. Web Services have become increasingly important both within and across organizational boundaries.  With the recent advent of the Semantic Web, web services have evolved into semantic web services whose components are described using machine understandable semantics. However, the discovery of semantic web services, the matching of user requirements to available services, still has a number of unanswered questions. In particular, there is criticism that current discovery methods focus exclusively on service inputs and outputs and ignore how services actually perform their tasks. This lack of information regarding how a service operates can also severely impact understanding of web service results. We show how ideas from data provenance - capturing the history and lineage of data - can be applied to web services.  We describe our approach to capture service provenance using Semantic Web technologies and subsequently design a new web service discovery algorithm around it. Further, we present a framework for capturing and integrating provenance in multi-service workflows.

description: We show that a properly designed bianisotropic metasurface placed at the interface between two arbitrary different media, or coating a dielectric medium exposed to the air, provides Brewster (reflectionless) transmission at arbitrary angles and for both the TM and TE polarizations. We present a rigorous derivation of the corresponding surface susceptibility tensors based on the Generalized Sheet Transition Conditions (GSTCs), and demonstrate the system with planar microwave metasurfaces designed for polarization-independent and azimuth-independent operations. Moreover, we reveal that such a system leads to the concept of effective refractive media with engineerable impedance. The proposed bianisotropic metasurfaces provide deeply subwavelength matching solutions for initially mismatched media, and alternatively lead to the possibility of on-demand manipulation of the conventional Fresnel coefficients. The reported generalized Brewster effect represents a fundamental advance in optical technology, where it may both improve the performance of conventional components and enable the development of novel devices.

description: The purpose of this study was to establish and analyze the impact of a collaborative professional development program across the disciplines among the faculty of the Foundation Program at the Petroleum Institute in Abu Dhabi, United Arab Emirates through the use of a lesson study model. Though widely used among teachers in the same discipline, lesson study has also been identified as a means of bridging the professional expertise of teachers across disciplines. This study is the first to report on the use of lesson study to integrate language and content instruction in a university preparation program. In this study, science, mathematics, and English teachers collaboratively developed and taught integrated lessons, observed these lessons being taught, discussed their impact upon students, and revised and re-taught the lessons with a new group of students. In the process, the teachers also reflected upon their own teaching practices and those of their colleagues in other disciplines by working together in a supportive and enriching cross-disciplinary environment. As a result, they were also able to provide instruction that helped make clear to students the relationships among the courses in which they were enrolled. Although time-consuming, the lesson study process was viewed as a valuable form of professional development. It promoted collaboration, increased curricular cohesion, and provided opportunities for teachers to reflect on their own practice and learn from each other. Recommendations for further study of lesson study and for extending the application of this model of professional development are also provided.

ANDROMEDA Project - D.7.6 Initial Workshops Organization and Results
Creators: name: Pantelis, Kanellopoulos
Publisher: name: Zenodo
Year: 2021

description: The current deliverable is a report of the activities made within Task 7.2 “Workshops Coordination” in regards to the organization of the first ANDROMEDA workshop that was held virtually on the 28th and 29th September 2020. These activities include the creation of event’s programme (Agenda), the invitations sent to potential attendees, the digital promotional material created and the announcements made via social media for raising the visibility of the event. It should be stressed that the physical workshop would have taken place in Tres Cantos (Spain) in early September of 2020 and preparatory activities towards its realization were made. After the outbreak of COVID-19, the ANDROMEDA consortium following the guidelines of national authorities, decided to turn the event from physical into a virtual one. Nevertheless, the core part of this document is dedicated in presenting the topics elaborated by the speakers and the discussions made.

description: We study the phase transition and the critical properties of a nonlinear Pólya urn, which is a simple binary stochastic process $X(t)\in \{0,1\},t=1,\cdots$ with a feedback mechanism. Let $f$ be a continuous function from the unit interval to itself, and $z(t)$ be the proportion of the first $t$ variables $X(1),\cdots,X(t)$ that take the value 1. $X(t+1)$ takes the value 1 with probability $f(z(t))$. When the number of stable fixed points of $f(z)$ changes, the system undergoes a non-equilibrium phase transition and the order parameter is the limit value of the autocorrelation function. When the system is $Z_{2}$ symmetric, that is, $f(z)=1-f(1-z)$, a continuous phase transition occurs, and the autocorrelation function behaves asymptotically as $\ln(t+1)^{-1/2}g(\ln(t+1)/ξ)$, with a suitable definition of the correlation length $ξ$ and the universal function $g(x)$. We derive $g(x)$ analytically using stochastic differential equations and the expansion about the strength of stochastic noise. $g(x)$ determines the asymptotic behavior of the autocorrelation function near the critical point and the universality class of the phase transition.

description: We describe the dynamics of quantum discord of two interacting spin-1/2 subjected to controllable time-dependent magnetic fields. The exact time evolution of discord is given for various input mixed states consisting of classical mixtures of two Bell states. The quantum discord manifests a complex oscillatory behaviour in time and is compared with that of quantum entanglement, measured by concurrence. The interplay of the action of the time-dependent magnetic fields and the spin-coupling mechanism in the occurrence and evolution of quantum correlations is examined in detail.

description: In this paper, we use the approximation of shallow water waves (Margaritondo G 2005 Eur. J. Phys. 26 401) to understand the behaviour of a tsunami in a variable depth. We deduce the shallow water wave equation and the continuity equation that must be satisfied when a wave encounters a discontinuity in the sea depth. A short explanation about how the tsunami hit the west coast of India is given based on the refraction phenomenon. Our procedure also includes a simple numerical calculation suitable for undergraduate students in physics and engineering.
The Responsive Layer: Steps Towards a Digital Augmentation System to Make Everyday Objects Responsive

subject: FOS: Civil engineering

description: Everyday objects are an integral part of our lives and are the daily physical interface between us and the world. The traditional way to make objects respond to human actions through digital technologies is through built-in hardware and software, combined with screen-based user interfaces. This thesis proposes an interactive system named Responsive Layer that enables users to add a layer of digital information on top of everyday objects through projection without the need for additional embedded sensors and interactive devices. The system combines projection mapping and computer vision technology to perceive the interaction between users and physical objects and responds with images and text. The thesis introduces an easy-to-operate system for designers and end-users to interact with everyday physical objects and spaces. The thesis first outlines the motivation and research goals. It then studies the background and related work to position the thesis. Next, it discusses the design and implementation details of the system, and prototypes used to test and improve the system. The development and observation of the five prototypes prove the feasibility, scalability and broad application prospects of the system. The first three prototypes simulated the interaction between a user and a folder, and tested the system's perception of users and objects, the recording and display of context information, and its playability. The fourth prototype showed how to design the reminder function of a cup. The last prototype demonstrated the feasibility of the system to track user movements in an architectural space.
STRUCTURAL EXPLORATIONS TO THE PURINE SCAFFOLD FOR USE IN NUCLEOSIDE DRUG DESIGN

description: Purines are one of the most ubiquitous heterocyclic ring systems in nature and consequently, they are components in numerous biologically significant molecules. As a consequence they possess an excellent scaffold that may be exploited to interrogate enzyme structure and function, as well as for the development of new, potent therapeutic compounds. There are numerous examples in the literature of modifications that truly highlight the immense utility of these heterocycles. Consequently, three different, yet structurally related series of modified nucleoside(tide) analogues were sought in this work. The first project describes the synthesis of a series of thieno-expanded purine 2'-deoxy analogues that were designed to interrogate nucleic acid structure and function as well as to potentially provide the framework for novel biological agents. The second project is directly related to the expanded analogues, and focuses on a group of 2'-deoxy flexible nucleoside analogues called fleximers. This new class of unique shape-modified nucleosides introduces flexibility to the heteroaromatic purine ring by splitting it into its two components (for example, an imidazole and pyrimidine ring). This imparts additional degrees of conformational freedom and torsional flexibility while still retaining the molecular elements necessary for recognition. These innovative nucleosides are an extension of two series of ribose fleximers previously introduced by the Seley-Radtke laboratories. It is hoped that this new series of fleximers will expand the repertoire of active compounds especially after observing the exciting biological results observed by the ribose series.  The third project highlights the use of thieno-expanded purine ribose derivatives, in the nucleoside as well as the triphosphate forms, as potential inhibitors of HCV. Motivation for this project was especially warranted following reports in the literature that inclusion of a pendant thiophene ring significantly increased inhibition against HCV for some inhibitors. All of the compounds that were pursued for this research have provided valuable information about nucleoside structure and function, as well as enzyme-ligand interactions, thereby providing a solid foundation for further study.

description: Currently the United States is home to a large and increasing immigrant population.  Many of these immigrant students use community-based programs for their educational needs. Despite the large number of immigrant students who currently use alternate resources, such as churches and community centers, for education, adult language learners in nonacademic settings remain understudied.  Today's students need language and literacy skills along with specialized skills required by the current globalizations of marketplaces.  Community organizations providing language and literacy services to immigrants need a better understanding of clients and how to provide the experiences that will allow their students to participate in the modern workforce and society.         This is a qualitative ethnographic study that follows nine Spanish-speaking adult males through one portion of their lives as recent immigrants. Using a sociocultural definition of literacy and portraiture as a method of analysis, this study looks at data obtained from classroom assignments, digital stories created by the subjects, and online social media to investigate the performance of identity across literacy events.       Analysis supported the existence of complex, hybrid, and situated identities for students.  Identity performance differed across literacy events and the inclusion of digital stories and online social media provided evidence of identities not present in traditional classroom activities.

Dualities among 1T-Field Theories with Spin, Emerging from a Unifying 2T-Field Theory

description: The relation between two time physics (2T-physics) and the ordinary one time formulation of physics (1T-physics) is similar to the relation between a 3-dimensional object moving in a room and its multiple shadows moving on walls when projected from different perspectives. The multiple shadows as seen by observers stuck on the wall are analogous to the effects of the 2T-universe as experienced in ordinary 1T spacetime. In this paper we develop some of the quantitative aspects of this 2T to 1T relationship in the context of field theory. We discuss 2T field theory in d+2 dimensions and its shadows in the form of 1T field theories when the theory contains Klein-Gordon, Dirac and Yang-Mills fields, such as the Standard Model of particles and forces. We show that the shadow 1T field theories must have hidden relations among themselves. These relations take the form of dualities and hidden spacetime symmetries. A subset of the shadows are 1T field theories in different gravitational backgrounds (different space-times) such as the flat Minkowski spacetime, the Robertson-Walker expanding universe, AdS(d-k) x S(k) and others, including singular ones. We explicitly construct the duality transformations among this conformally flat subset, and build the generators of their hidden SO(d,2) symmetry. The existence of such hidden relations among 1T field theories, which can be tested by both theory and experiment in 1T-physics, is part of the evidence for the underlying d+2 dimensional spacetime and the unifying 2T-physics structure.
