description: We investigate the cost-effectiveness and distributional effects of a revenue-raising auction, grandfathering, and a generation performance standard as alternative approaches for distributing carbon emission allowances in the electricity sector. We solve a detailed national electricity market model and find the auction is roughly one-half the societal cost of the other approaches. This result holds under a variety of assumptions about the future state of economic regulation and competition in the electricity sector. The differences in the cost of the approaches flow from the effect of each approach on electricity price. Grandfathering is the best for producers but it imposes a substantial cost on consumers. The generation performance standard yields the lowest electricity price but highest natural gas price. The auction does better than the generation performance standard at protecting households and at preserving asset values for producers. It also yields revenues that can help meet other efficiency and distributional goals.

description: Estimates of marginal abatement costs for reducing carbon emissions in the United States by the major economic-energy models vary by a factor of five, undermining support for mandatory policies to reduce greenhouse gas emissions. We use meta analysis to explain these cost differences, holding policy regimes constant and focusing on the role of baseline emissions projections and structural characteristics of the models. The results indicate that certain assumptions, like freer trade and greater disaggregation of regions and nonenergy goods, lead to lower estimates of marginal abatement costs, while more disaggregated energy goods raise them. Other choices, like myopic optimization by households or the inclusion of an international finance sector, seem less significant. Nor do emissions baseline differences explain much of the cost differences. Our analysis can help indicate which modeling assumptions are most important to understanding the cost discrepancies and developing consistent modeling practices for policy evaluation.

description: This paper suggests two theoretically consistent and empirically tractable ways that a cost-ofliving index can be expanded to include the environment and other public goods. In addition, it presents an empirical illustration of such an index for Los Angeles, California, incorporating air quality and other spatially varying public goods using a hedonic model. The results indicate that the required information can be recovered and that including public goods can make a noticeable difference in the index.

description: We report results of magnetization and $^{31}$P NMR measurements under high pressure up to 6.4~GPa on RbMoOPO$_4$Cl, which is a frustrated square-lattice antiferromagnet with competing nearest-neighbor and next-nearest-neighbor interactions. Anomalies in the pressure dependences of the NMR shift and the transferred hyperfine coupling constants indicate a structural phase transition at 2.6~GPa, which is likely to break mirror symmetry and triggers significant change of the exchange interactions. In fact, the NMR spectra in magnetically ordered states reveal a change from the columnar antiferromagnetic (CAF) order below 3.3~GPa to the Néel antiferromagnetic (NAF) order above 3.9~GPa. The spin lattice relaxation rate $1/T_1$ also indicates a change of dominant magnetic fluctuations from CAF-type to NAF-type with pressure. Although the NMR spectra in the intermediate pressure region between 3.3 and 3.9 GPa show coexistence of the CAF and NAF phases, a certain component of $1/T_1$ shows paramagnetic behavior with persistent spin fluctuations, leaving possibility for a quantum disordered phase. The easy-plane anisotropy of spin fluctuations with unusual nonmonotonic temperature dependence at ambient pressure gets reversed to the Ising anisotropy at high pressures. This unexpected anisotropic behavior for a spin 1/2 system may be ascribed to the strong spin-orbit coupling of Mo-4$d$ electrons.

The effect of reflective abstraction versus peer-focused discussions on the promotion of moral development and prosocial behavior : an intervention study
Creators: name: Binfet, John Tyler
Publisher: name: University of British Columbia
Year: 2009

description: According to cognitive-developmental theorists, cognitive conflict is the mechanism responsible for both cognitive and moral growth. Cognitive conflict may be generated through two distinct pathways: interindividually, in which individuals interact with each other thus exposing one another to a variety of views and opinions; and intraindividually, or what Piaget termed reflective abstraction, a process in which an individual engages in a form of solitary mental reflection in response to information or stimuli that contrast or conflict with the information the individual currently possesses. The goals of this study were twofold. The first goal was to examine the effects of two distinct moral reasoning interventions on moral reasoning development: an interindividual or social intervention in which students participated in moral dilemma discussions and an intraindividual or individual intervention in which students participated in reflective abstraction concerning the issues prevalent within a series of moral dilemmas. The second goal of this study was to examine the effects of the aforementioned moral reasoning interventions on self-, peer-, and teacher-ratings of prosocial and antisocial behaviors. Ninety-seven sixth and seventh grade students attending public school in a large, metropolitan Western Canadian city participated in the study. Participants were randomly assigned to one of four groups: a moral discussion group, a placebo discussion group, a moral reflection group, and a placebo reflection group. The interventions occurred over a ten-week period involving one 40-minute period per week. Gibbs' Social Moral Reflection Measure - Short Form (Gibbs, Basinger, & Fuller, 1992) was used to assess pre- and post- levels of moral reasoning. Additionally, pre-and posttest measures of self-, peer-, and teacher-ratings of behavior were administered. The results indicated that a) there was no difference in moral reasoning between students in the two experimental groups, b) students in both experimental groups made significant gains in moral reasoning when compared to students in their respective placebo groups, and c) although no difference was found in self-ratings of prosocial and antisocial behavior, several differences were found across groups with respect to peer- and teacher-ratings of prosocial and antisocial behavior. The findings from this study contribute both theoretically and practically to the field of moral education. From a theoretical perspective, the results of this study challenge conventional thinking concerning the different means through which moral reasoning may be facilitated. Certainly, the findings validate the role that reflective abstraction plays in fostering moral development. From a practical perspective, the findings provide strategies for educators interested in promoting both moral development and prosocial behavior in the classroom.
The Free-Free Opacity in Warm, Dense, and Weakly Ionized Helium

description: We investigate the ionization and the opacity of warm, dense helium under conditions found in the atmospheres of cool white dwarf stars. Our particular interest is in densities up to $\rm 3 g/cm^{3}$ and temperatures from 1000K to 10000K. For these physical conditions various approaches for modeling the ionization equilibrium predict ionization fractions that differ by orders of magnitudes. Furthermore, estimates of the density at which helium pressure-ionizes vary from $\rm 0.3$ to $\rm 14 g/cm^{3}$. In this context, the value of the electron-atom inverse bremsstrahlung absorption is highly uncertain. We present new results obtained from a non-ideal chemical model for the ionization equilibrium, from Quantum Molecular Dynamics (QMD) simulations, and from the analysis of experimental data to better understand the ionization fraction in fluid helium in the weak ionization limit.

description: A mobility edge (ME) in energy separating extended from localized states is a central concept in understanding various fundamental phenomena like the metal-insulator transition in disordered systems. In one-dimensional quasiperiodic systems, there exist a few models with exact MEs, and these models are beneficial to provide exact understanding of ME physics. Here we investigate two widely studied models including exact MEs, one with an exponential hopping and one with a special form of incommensurate on-site potential. We analytically prove that the two models are mutually dual, and further give the numerical verification by calculating the inverse participation ratio and Husimi function. The exact MEs of the two models are also obtained by calculating the localization lengths and using the duality relations. Our result may provide insight into realizing and observing exact MEs in both theory and experiment.

description: An organization is a group of persons who satisfy an established membership requirement. Membership requirements may be based on inherited or earned traits. Organizations provide a place for social capital to reside. Organizations exist because they provide the setting in which members can meet their economic, social, validation, and information needs. As the needs of members change, membership requirements and organizational emphasis may also change. Relationships among an organization's members range from antipathetic to sympathetic. Depending on the quality of relationships or social capital within an organization, power will be exercised using a stick, carrot, and hug. Organizations may experience conflict if members perceive they must compete with each other to satisfy their needs. Finally, in a two-person relationship, social capital is likely to be symmetric or exploitation may exist. In more complicated relationships, social capital is likely to satisfy adding up constraints.

description: Hamilton in the course of his studies on quaternions came up with an elegant geometric picture for the group SU(2). In this picture the group elements are represented by ``turns'', which are equivalence classes of directed great circle arcs on the unit sphere $S^2$, in such a manner that the rule for composition of group elements takes the form of the familiar parallelogram law for the Euclidean translation group. It is only recently that this construction has been generalized to the simplest noncompact group $SU(1,1) = Sp(2, R) = SL(2,R)$, the double cover of SO(2,1). The present work develops a theory of turns for $SL(2,C)$, the double and universal cover of SO(3,1) and $SO(3,C)$, rendering a geometric representation in the spirit of Hamilton available for all low dimensional semisimple Lie groups of interest in physics. The geometric construction is illustrated through application to polar decomposition, and to the composition of Lorentz boosts and the resulting Wigner or Thomas rotation.

Qualitative and quantitative features of orbits of massive particles and photons moving in Wyman geometry

description: The Wyman's solution depends on two parameters, the mass $M$ and the scalar charge $σ$. If one fixes $M$ to a positive value, say $M_0$, and let $σ^2$ take values along the real line it describes three different types of spacetimes. For $σ^2 >0$ the spacetimes are naked singularities, for $σ^2 = 0$ one has the Schwarzschild black hole of mass $M_0$ and finally for $-M_0^2 \leq σ^2 < 0$ one has wormhole spacetimes. In the present work, we shall study qualitative and quantitative features of orbits of massive particles and photons moving in the naked singularity and wormhole spacetimes of the Wyman solution. These orbits are the timelike geodesics for massive particles and null geodesics for photons. Combining the four geodesic equations with an additional equation derived from the line element, we obtain an effective potential for the massive particles and a different effective potential for the photons. We investigate all possible types of orbits, for massive particles and photons, by studying the appropriate effective potential. We notice that for certain values of $σ^2 >0$, there is an infinity potential wall that prevents both massive particles and photons ever to reach the naked singularity. We notice, also, that for certain values of $-M_0^2 \leq σ^2 < 0$, the potential is finite everywhere, which allows massive particles and photons moving from one wormhole asymptotically flat region to the other. We also compute the radial timelike and null geodesics for massive particles and photons, respectively, moving in the naked singularities and wormholes spacetimes.

A simple algorithm for global sensitivity analysis with Shapley effects
Creators: name: Goda, Takashi
Publisher: name: arXiv
Year: 2020
Subjects: subject: Computation (stat.CO)
subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: Global sensitivity analysis aims at measuring the relative importance of different variables or groups of variables for the variability of a quantity of interest. Among several sensitivity indices, so-called Shapley effects have recently gained popularity mainly because the Shapley effects for all the individual variables are summed up to the overall variance, which gives a better interpretability than the classical sensitivity indices called main effects and total effects. In this paper, assuming that all the input variables are independent, we introduce a quite simple Monte Carlo algorithm to estimate the Shapley effects for all the individual variables simultaneously, which drastically simplifies the existing algorithms proposed in the literature. We present a short Matlab implementation of our algorithm and show some numerical results. A possible extension to the case where the input variables are dependent is also discussed.
Tropenkoller. States of agitation and mood swings in colonial jurisdiction in the German colonies
Creators: name: Schaper, Ulrike
Publisher: name: InterDisciplines. Journal of History and Sociology
Year: 2015

description: The term Tropenkoller emerged in the context of several scandals concerning incidents of excessive violence in the German colonies, predominantly in cases of criminal jurisdiction in the mid-1890s. Tropenkoller was understood as a state of excitation produced by the nerves in reaction to medical, social, and climactic conditions in the colonies. References to Tropenkoller in the context of these scandals were used to legitimize excessive violence as well as to criticize this apologetic rhetoric. The incidents the term referred to, however, contradicted the colonial authorities’ self-perception of rationality and control, which formed a basis for their claim to colonial power. State representatives who acted under the influence of Tropenkoller—I argue—were seen as problematic, especially because they behaved emotionally and recklessly. In analyzing how Tropenkoller was problematized in the context of colonial jurisdiction, I assess feelings of a plenitude of power and the lust for violence, as well as the role that feelings of mental overload and loneliness played in the discussion. I seek to demonstrate the extent to which colonial authorities perceived these feelings, and the uninhibited expression of such feelings, as both a danger to jurisdiction and to the colonial state, and as such as something that had to be excluded from court proceedings. I argue that the occurrence of Tropenkoller among colonial officials, seen as a result of the failure of personal tropical hygiene measures to help state representatives to maintain self-control, met with a barely-regulated colonial jurisdiction. Furthermore, I examine the measures proposed to counter this problematic emotionality.

description: High pressure effects on the superconducting transitions of beta-pyrochlore superconductors AOs2O6 (A = Cs, Rb, K) are studied by measuring resistivity under high pressures up to 10 GPa. The superconducting transition temperature Tc first increases with increasing pressure in all the compounds and then exhibits a broad maximum at 7.6 K (6 GPa), 8.2 K (2 GPa) and 10 K (0.6 GPa) for A = Cs, Rb and K, respectviely. Finally, the superconductivity is suppressed completely at a critical pressure near 7 GPa and 6 GPa for A = Rb and K and probably above 10 GPa for A = Cs. Characteristic changes in the coefficinet A of the T2 term in resistivity and residual resistivity are observed, both of which are synchronized with the corresponding change in Tc. It is suggested that electron correlations and certain quantum fluctuations play important roles in the occurrence or suppression of superconductivity in the beta-pyrochlore oxides.

description: Due to the lack of a net magnetization both at the interface and in the bulk, antiferromagnets with compensated interfaces may appear incapable of influencing the phase transition in an adjacent superconductor via the spin degree of freedom. We here demonstrate that such an assertion is incorrect by showing that proximity-coupling a compensated antiferromagnetic layer to a superconductor-ferromagnet heterostructure introduces the possibility of controlling the superconducting phase transition. The superconducting critical temperature can in fact be modulated by rotating the magnetization of the single ferromagnetic layer within the plane of the interface, although the system is invariant under rotations of the magnetization in the absence of the antiferromagnetic layer. Moreover, we predict that the superconducting phase transition can trigger a reorientation of the ground state magnetization. Our results show that a compensated antiferromagnetic interface is in fact able to distinguish between different spin-polarizations of triplet Cooper pairs.

Year: 2005
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We consider the couplings of an infinite number of spin-2 fields to gravity appearing in Kaluza-Klein theories. They are constructed as the broken phase of a massless theory possessing an infinite-dimensional spin-2 symmetry. Focusing on a circle compactification of four-dimensional gravity we show that the resulting gravity/spin-2 system in D=3 has in its unbroken phase an interpretation as a Chern-Simons theory of the Kac-Moody algebra associated to the Poincare group and also fits into the geometrical framework of algebra-valued differential geometry developed by Wald. Assigning all degrees of freedom to scalar fields, the matter couplings in the unbroken phase are determined, and it is shown that their global symmetry algebra contains the Virasoro algebra together with an enhancement of the Ehlers group to its affine extension. The broken phase is then constructed by gauging a subgroup of the global symmetries. It is shown that metric, spin-2 fields and Kaluza-Klein vectors combine into a Chern-Simons theory for an extended algebra, in which the affine Poincare subalgebra acquires a central extension.

description: The degree and orientation of the magnetic-field induced linear polarization of the photoluminescence from a wide range of heterostructures containing (Cd,Mn)Te quantum wells between (Cd,Mn,Mg)Te barriers has been studied as a function of detection photon energy, applied magnetic field strength and orientation in the quantum well plane. A theoretical description of this effect in terms of an in-plane deformation acting on the valence band states is presented and is verified by comparison with the experimental data. We attempted to identify clues to the microscopic origin of the valence band spin anisotropy and to the mechanisms which actually determine the linear polarization of the PL in the quantum wells subject to the in-plane magnetic field. The conclusions of the present paper apply in full measure to non-magnetic QWs as well as ensembles of disk-like QDs with shape and/or strain anisotropy.

The jurist as manager of emotions. German debates on »Rechtsgefühl« in the late 19th and early 20th century as sites of negotiating the juristic treatment of emotions

description: During the late 19th and early 20th century, a variety of jurisprudential texts that focus on the role of Rechtsgefühl in law and legal practice were published. This article first inquires into the meanings of this term, asking whether it denoted an innate sense of justice, a common feeling for the law, or a trained juristic intuition. In turn, this opens up the question of how the relation between law and emotions was conceived and how this conception was related to the practice of jurisprudence. As I will show, the juristic debate on the Rechtsgefühl mirrored the influence of changing interpretive patterns for the definition of law as well as that of emotion, patterns which were adapted from the newly developing natural sciences. They shaped not only how Rechtsgefühl was defined, but also the function attributed to it in juridical practice. I argue that the ideas and rules of bourgeois culture strongly defined the way the jurist was required to treat his Rechtsgefühl and his emotions in general. Not only his professional success, but also his quality of character and his bourgeois masculinity were to be proven by his success as a »manager of emotions.«

We construct a well-behaved action principle for such spacetimes, using the formalism developed by Mann and Marolf. We show that this action is finite on-shell and that the variational principle is well-defined for solutions of vacuum gravity satisfying our asymptotically plane wave falloff conditions.

It analyses the emotion work of Stuttgart’s criminal police department in homicide cases from the 1950s to the 1970s. This emotion work will in turn be explored using a performative studies concept: The police hearings will be addressed asAufführungenas conceived by Erika Fischer-Lichte—that is as performances that rely on a specific text and are characterized by the physical co-presence and shifting roles of actors and spectators in a specific place and for a certain amount of time. The analysis draws on files in which male residents from Italy were charged with homicide or attempted murder.

Despite the spectacular success of the algorithm in many application areas such as iterative decoding, computer vision and combinatorial optimization which involve graphs with many cycles, theoretical results about both correctness and convergence of the algorithm are known in few cases (Weiss-Freeman Wainwright, Yeddidia-Weiss-Freeman, Richardson-Urbanke}. In this paper we consider the problem of finding the Maximum Weight Matching (MWM) in a weighted complete bipartite graph. We define a probability distribution on the bipartite graph whose MAP assignment corresponds to the MWM. We use the max-product algorithm for finding the MAP of this distribution or equivalently, the MWM on the bipartite graph. Even though the underlying bipartite graph has many short cycles, we find that surprisingly, the max-product algorithm always converges to the correct MAP assignment as long as the MAP assignment is unique. We provide a bound on the number of iterations required by the algorithm and evaluate the computational cost of the algorithm. We find that for a graph of size $n$, the computational cost of the algorithm scales as $O(n^3)$, which is the same as the computational cost of the best known algorithm. Finally, we establish the precise relation between the max-product algorithm and the celebrated {\em auction} algorithm proposed by Bertsekas. This suggests possible connections between dual algorithm and max-product algorithm for discrete optimization problems.

description: Digital-analog quantum computation aims to reduce the currently infeasible resource requirements needed for near-term quantum information processing by replacing sequences of one- and two-qubit gates with a unitary transformation generated by the systems' underlying Hamiltonian. Inspired by this paradigm, we consider superconducting architectures and extend the cross-resonance effect, up to first order in perturbation theory, from a two-qubit interaction to an analog Hamiltonian acting on 1D chains and 2D square lattices which, in an appropriate reference frame, results in a purely two-local Hamiltonian. By augmenting the analog Hamiltonian dynamics with single-qubit gates we show how one may generate a larger variety of distinct analog Hamiltonians. We then synthesize unitary sequences, in which we toggle between the various analog Hamiltonians as needed, simulating the dynamics of Ising, $XY$, and Heisenberg spin models. Our dynamics simulations are Trotter error-free for the Ising and $XY$ models in 1D. We also show that the Trotter errors for 2D $XY$ and 1D Heisenberg chains are reduced, with respect to a digital decomposition, by a constant factor. In order to realize these important near-term speedups, we discuss the practical considerations needed to accurately characterize and calibrate our analog Hamiltonians for use in quantum simulations. We conclude with a discussion of how the Hamiltonian toggling techniques could be extended to derive new analog Hamiltonians which may be of use in more complex digital-analog quantum simulations for various models of interacting spins.
Relations of autonomy and relatedness to school functioning and psychological adjustment during adolescence

description: One criticism of previous work in the field of adolescent development has been the paucity of research examining the unique and combined contributions of different developmental contexts on adolescents' functioning. In an attempt to address this issue, the current study examined adolescents' perceptions of autonomy and relatedness within parent, peer, and school contexts in relation to school functioning and psychological adjustment. Adolescents (N = 478) in Grades 8, 9, and 11 completed self-report questionnaires assessing feelings about their relationships with parents and peers, and perceptions of school. Teachers completed ratings of adolescents' strengths and competencies. Academic achievement was assessed using end of year school grades. Results revealed several significant gender and grade differences. Whereas girls reported greater deidealization of their parents and peers, and higher quality of attachment to peers than did boys, boys- reported being less dependent on their peers than did girls. Overall, adolescents in grade nine were more dependent on their peers and reported more trust and communication in their peer relationships than did adolescents in grade eight. Correlational results indicated that school functioning was positively associated with school autonomy, parental attachment, peer attachment and school belonging, and that problems in psychological adjustment were negatively associated with peer autonomy, school autonomy, parental attachment, peer attachment, school belonging, and positively associated with parental autonomy. Results of the multiple regression analyses indicated that autonomy and relatedness variables accounted for significant amounts of variance in GPA, teacher-rated school competencies, internalizing problems, and externalizing problems. Analyses also revealed variables which uniquely predicted areas of functioning across contexts and gender. This cross-sectional study provides new theoretical insights regarding relations of autonomy and relatedness to school functioning and psychological adjustment during adolescence across multiple contexts. The findings contribute to a more thorough understanding of the dimensions of autonomy and relatedness that may have important implications for educators and parents of adolescents for improving educational practice and for promoting school success and positive adjustment.
ANALYSIS OF ALTERNATIVE PAYMENT DESIGNS FOR FARMLAND DEVELOPMENT RIGHTS

description: Four alternative payment rules were examined to evaluate their ability to accomplish the objectives of the development rights purchase program. Paying the true economic value for the development rights does not allow the program to target high quality agricultural land. Modifying the payment strategy by offering a minimum payment will provide some extra incentive for high quality agricultural land in areas with little development pressure, but will provide little help in areas with high development pressure. Indexing the payment to a representative agricultural-use value for an area will provide premiums to high quality agricultural land and discounts to low quality agricultural land which provides additional incentives (disincentives) for high (low) quality land to enter the program. This representative payment rule can be modified in order to increase the participation incentives to owners of targeted land.

description: This report presents a general assessment of the demand and supply conditions affecting the Michigan frozen potato industry. The information has been drawn from various secondary sources and interviews with key industry informants. The report is one of the major outputs of an ongoing study being prepared for the Michigan Potato Industry Commission and funded by the Michigan Agricultural Experiment Station. This analysis was necessitated by the 80% reduction in Michigan frozen processing potato acreage by Simplot in 1997. This reduction of 5,000 acres for the Grand Rapids processing facility has created both short-term and long-term concerns for the Michigan potato industry. This assessment provides broad background information relevant to determining why this cutback occurred and its likely impact if continued in the future. The report begins with a consideration of demand conditions, including both domestic and international demand trends for consumption and consumer preferences. The report then discusses supply issues, including current North American production capacity, international sourcing trends, competition from Canadian imports, cost considerations, processing innovation, and industry consolidation. The report concludes with a section addressing key strategic issues suggested by the demand and supply trends. NOTE: This staff paper contains text only.

description: The Planck mission will permit measurements of the polarization of the cosmic microwave background and of polarized foregrounds such as our own Galaxy with an unprecedented combination of accuracy and completeness. This will provide information on cosmological and galactic magnetic fields. The latter can be studied in detail via nearly Faraday-rotation free synchrotron and polarized dust emission. Methods are discussed to extract physically relevant information on the magnetic turbulence from Planck data and other measurements.

title: Investigating Virtual Reality for Enhanced Educational Engagement

description: Virtual reality (VR) is an innovative technology that has regained
 popularity in

 recent years. In the field of education, VR has been introduced as a tool
 to enhance learning experiences. This thesis presents an exploration of
 how VR is used from the context of educators and learners. The research
 employed a mixed-methods approach, including surveying and interviewing
 educators, and conducting empirical studies to examine engagement,
 usability, and user behaviour within VR.

 The results revealed educators are interested in using VR for a wide range
 of

 scenarios, including thought exercises, virtual field trips, and
 simulations.

 However, they face several barriers to incorporating VR into their
 practice, such

 as cost, lack of training, and technical challenges.

 A subsequent study found that virtual reality can no longer be assumed to
 be

 more engaging than desktop equivalents. This empirical study showed that

 engagement levels were similar in both VR and non-VR environments,
 suggesting that the novelty effect of VR may be less pronounced than
 previously assumed.

 A study against a VR mind mapping artifact, VERITAS, demonstrated that

 complex interactions are possible on low-cost VR devices, making VR
 accessible

 to educators and students. The analysis of user behaviour within this VR
 artifact

 showed that quantifiable strategies emerge, contributing to the
 understanding of how to design for collaborative VR experiences.

 This thesis provides insights into how the end-users in the education
 space

 perceive and use VR. The findings suggest that while educators are
 interested in

 using VR, they face barriers to adoption. The research highlights the need
 to

 design VR experiences, with understanding of existing pedagogy, that are

 engaging with careful thought applied to complex interactions,
 particularly for

 collaborative experiences. This research contributes to the understanding
 of the

 potential of VR in education and provides recommendations for educators
 and

 designers to enhance learning experiences using VR.
