description: We consider a simple extension of the standard model with a singlet fermionic dark matter. Its thermal relic density can be easily accommodated by a real singlet scalar messenger that mixes with the standard model Higgs boson. The model can change significantly the Higgs signals at the LHC via sizable invisible decays of two Higgs-like scalar bosons. After imposing the constraints from the electroweak precision tests, colliders and dark matter search experiments, one concludes that two or one or none of the two Higgs bosons, depending on the mass relations among two scalar bosons and the dark matter fermion and their couplings. In particular, if a standard model Higgs-like scalar boson is discovered around 120--125 GeV region at the LHC, it would be almost impossible to find the second Higgs-like boson since it is mostly a singlet scalar, whether it is heavier or lighter. This model can be further tested by direct dark matter search experiments.

description: The cerebellum contains 80% of all neurons in the human brain and contributes prominently to implicit learning and predictive processing across motor, sensory, and cognitive domains. As morphological features of the cerebellum in atypically developing individuals remain unexplored in-vivo, this is the first study to use high-resolution 3D fractal analysis to estimate fractal dimension (FD), a measure of structural complexity of an object, of the left and right cerebellar cortex (automatically segmented from Magnetic Resonance Images using FreeSurfer), in male children with Autism Spectrum Disorders (ASD) (N = 20; mean age: 8.8 years old, range: 7.13–10.27) and sex, age, verbal-IQ, and cerebellar volume-matched typically developing (TD) boys (N = 18; mean age: 8.9 years old, range: 6.47–10.52). We focus on an age range within the ‘middle and late childhood’ period of brain development, between 6 and 12 years. A Mann-Whitney U test revealed a significant reduction in the FD of the right cerebellar cortex in ASD relative to TD boys (P = 0.0063, Bonferroni-corrected), indicating flatter and less regular surface protrusions in ASD relative to TD males. Consistent with the prediction that the cerebellum participates in implicit learning, those ASD boys with a higher (vs. lower) PIQ>VIQ difference showed higher, more normative complexity values, closer to TD children, providing new insight on our understanding of the neurological basis of differences in verbal and performance cognitive abilities that often characterize individuals with ASD.

description: The strong capacity of a particular channel can be interpreted as a sharp limit on the amount of information which can be transmitted reliably over that channel. To evaluate the strong capacity of a particular channel one must prove both the direct part of the channel coding theorem and the strong converse for the channel. Here we consider the strong converse theorem for the periodic quantum channel and show some rather surprising results. We first show that the strong converse does not hold in general for this channel and therefore the channel does not have a strong capacity. Instead, we find that there is a scale of capacities corresponding to error probabilities between integer multiples of the inverse of the periodicity of the channel. A similar scale also exists for the random channel.

title: Eco-certification, assessments, and advice: implications of market measures for traditional practices

Subjects: Fisheries and aquaculture

description: No abstracts are to be cited without prior reference to the author.The eco-certification standards necessary to be consistent with international guidelines from the FAO greatly expand the factors to be considered in “assessing” a stock and fishery. The actual assessments are done by small panels of selected experts, and it is fisheries and not States that formally request certification (and the assessments required to be certified). Nonetheless, the panel assessments are in large part critical reviews of work submitted by the applicant(s) for certification. The analytical work traditionally associated with a “fishery assessment” will usually have been done by agencies or under contract. To the extent that States in support of their fisheries or the fisheries themselves want to use traditional sources of science advice as the basis for their submissions of “assessments” to the expert panels doing the certification evaluations, the ecocertification standards require the traditional contents of an “assessment” to be reviewed. In this paper, experience with both the ICES and Canadian fisheries and ecosystem assessment processes and with several eco-certification evaluation panels is applied as a basis for such a review. The P1 Marine Stewardship Council (MSC) certification standards deal with the status of the target species of the fishery and the direct impacts of the fishery on the target species. The P2 standards deal with the impact of the fishery on the ecosystem in general. For P1 the degree to which “standard assessment practice” produces results that are sufficient for an eco-certification assessment against P1 is considered. For P2, what an “ecosystem assessment” would have to address in order to be sufficient to inform a certification panel regarding the sustainability of impacts of a fishery relative to the ecosystem is outlined.

description: We present deep observations of the 12CO(1-0) and (3-2) lines in the ultra-luminous infrared and radio galaxy 4C12.50, carried out with the 30m telescope of the Institut de Radioastronomie Millimetrique. Our observations reveal the cold molecular gas component of a warm molecular gas outflow that was previously known from Spitzer Space Telescope data. The 12CO(3-2) profile indicates the presence of absorption at -950 km/s from systemic velocity with a central optical depth of 0.22. Its profile is similar to that of the HI absorption that was seen in radio data of this source. A potential detection of the (0-1) absorption enabled us to place an upper limit of 0.03 on its central optical depth, and to constrain the excitation temperature of the outflowing CO gas to >=65K assuming that the gas is thermalized. If the molecular clouds fully obscure the background millimeter continuum that is emitted by the radio core, the H2 column density is >=1.8*10^22 /cm^2. The outflow then carries an estimated cold H2 mass of at least 4.2*10^3 M_sun along the nuclear line of sight. This mass will be even higher when integrated over several lines of sight, but if it were to exceed 3*10^9 M_sun, the outflow would most likely be seen in emission. Since the ambient cold gas reservoir of 4C12.50 is 1.0*10^10 M_sun, the outflowing-to-ambient mass ratio of the warm gas (37%) could be elevated with respect to that of the cold gas.

description: No abstracts are to be cited without prior reference to the author.The Marine Stewardship Council (MSC) has pioneered the development of fishery certification and achieved rapid growth in its first 10 years. In North Atlantic (ICES) waters and around the world,more and more industry clients are entering assessment against the MSC programme, with the aim of demonstrating their green credentials and to gain access to the MSC eco-label. This paper emphasizes the need for information to be available for these fisheries, relating to the status of target stocks, and on bycatch species, habitats, and the wider ecosystem. The paper describes how the MSC has evolved since it was established 10 years ago, and outlines the MSC fisheries and supply chain standards and methodologies. The scope of the programme now includes ”enhanced fisheries” usually involving some combination of wild harvest and culture. MSC’s new risk-based framework has also improved accessibility of the programme to small-scale and data-limited fisheries in the developing world and elsewhere. The experiences of scientists working as assessment team members and peer reviewers within the assessment process are described, as is the way in which scientific data are used in MSC assessments. Against this background information, the paper confirms the consistency of the MSC scheme with international guidelines, including the FAO 2005 Guidelines on eco-labelling and the ISEAL Code of Good Practice on Standard Setting. MSC’s work on monitoring and evaluating the impacts of the programme is covered in a companion paper.

Ḥayātī’s account—dedicated, in 961/1554, to Shah Ṭahmāsp’s sister, Princess Mihīn Begum (d. 969/1562)—spans the period between the formative years of the Ṣafaviyya Sufi order under Ṣafī al-Dīn Isḥāq Ardabīlī (d. 735/1334) and the early years of the reign of Shah Ismāʿīl (907–30/1501–24). Emphasis is given to the way in which it fills in the gaps of our knowledge insofar as the pre-dynastic and early dynastic phases of Ṣafavid history as well as the administrative history of the Ṣafavid shrine in Ardabīl are concerned.
Designs for computer experiments : random versus rational
Creators: name: Gustafsson, Emelie Anna
Publisher: name: University of British Columbia

description: Computer experiments facilitate, through mathematical modelling, various experiments that would otherwise be very difficult to perform, or even impossible. Computer experiments are employed to emulate situations in areas such as weather modelling, astrophysics, economics and many more. In conducting a computer experiment, we are required to select a design for the initial values x⁽¹⁾, . . . , x(n) of a process, and then emulate the output based on the process and the initial values. The quality of the emulator therefore depends partly on the process and partly on the choice of initial values. We will only consider the Gaussian Process in this thesis, and the focus of our analysis will be on the selection of initial values. We consider the effects of selecting a random versus a rational design for the initial values of computer experiments. We aim to study a broad range of possible computer models that are likely to arise in practice. Therefore, we present the analysis of eight different design choices, each of which is either random or rational, for the initial values. These initial values are applied to five different test functions that we consider to be prevalent in practice. We observe the effect of each of the designs on each of the test functions at three different sample sizes. The goal of this thesis is to present a comprehensive study of various standard design choices and make recommendations to a practitioner on a robust design for the initial values of a computer experiment on a given function. As well as ultimately recommend a universally robust design for the initial values of any computer experiment.

description: Successful experiments for developing community-based health services often end without contributing to reform of large-scale programme implementation. In Ghana, however, the national implementation of community-based primary health care services, policy formation and action has been grounded in a continuous process of evidence-based planning. Originally launched as a three-village pilot project located in a single rural district, community-based health care in Ghana currently reaches over 3,000 communities dispersed in all 212 districts. This successful expansion of evidence-based health care has been the outcome of embedding science into the management systems. Beginning with diagnostic systems research and followed by phases for experimentation, replication, and scaling-up, the implementation of community-based primary health care has been guided by science that aims to improve the pace of programme expansion, the quality and intensity of community-based care, and reform of national operations when problems arose. In this process, embedding implementation science into routine national programming has sustained research utilization, clarified milestones, and accelerated the pace of scaling up progress. By providing insights into practical actions that can improve functioning, results from embedded research function as a component of programme management rather than something that researchers are challenged to hand over to policy makers and managers.

A time-of-flight analysis reveals a pronounced enhanced density peak in the backscattering direction $-v_0$, a feature reminiscent of coherent backscattering. Detailed numerical simulations indicate however that other effects also contribute to this enhancement, including a "backscattering echo" due to the position-momentum correlations of the initial wave packet.

Subjects: Fisheries and aquaculture

description: No abstracts are to be cited without prior reference to the author.The Marine Stewardship Council (MSC) released a new Fishery Assessment Methodology (FAM) in 2009. Several low trophic level (LTL) fisheries have already been certified within the MSC programme, and several more are under assessment, including Gulf of California sardine and an Antarctic krill fishery. Although the FAM makes special reference to requirements for assessing the sustainability of LTL fisheries, some stakeholders questioned whether further guidance or modification to requirements were required. In response, the MSC established a Low Trophic Level Fisheries Working Group in July 2009 to address this issue. The Working Group has held two workshops of stakeholders to discuss issues concerning certification of LTL fisheries, including selection of appropriate reference points and harvest strategies, appropriate spatial management strategies for central place foragers, and considering the impacts of environmental forcing. As part of the review process, the Working Group commissioned a scientific study to evaluate the impacts of fishing LTL species on other parts of the ecosystem. The scientific study used existing ecosystem models for a range of fishery ecosystems to evaluate the impacts of fishing LTL species on their predators and prey, and on other parts of the ecosystem. Although the results of this scientific study are aligned with the review process, the approach and outcomes are very relevant to the management of LTL fisheries in the absence of MSC assessment and certification. The outcomes of the public consultation and the scientific study will be presented and their implications discussed.

description: A superconducting flux qubit is inductively coupled to a Superconducting QUantum Interference Device (SQUID) magnetometer, capacitively shunted to form a 1.294-GHz resonator. The qubit-state-dependent resonator frequency is weakly probed with a microwave signal and detected with a Microstrip SQUID Amplifier. At a mean resonator occupation $\bar{n}$ = 1.5 photons, the readout visibility is increased by a factor of 4.5 over that using a cryogenic semiconductor amplifier. As $\bar{n}$ is increased from 0.008 to 0.1, no reduction in $T_1$ is observed, potentially enabling continuous monitoring of the qubit state.

description: No abstracts are to be cited without prior reference to the author.The impact of a fishery eco-labelling system is linked to its standards: their scientific basis and rigorous application; the robustness of the system’s assessment procedures and mechanisms ensuring transparency and participatory engagement. Other contributors to impact include number and volume of certified fisheries and labelled products, and extent of market support. Studies demonstrate the Marine Stewardship Council (MSC) performs well against measures of effectiveness. Following ten years of implementation there is interest in demonstrating the MSC’s impact on fisheries and associated ecosystems through objective, science-based analysis. Evaluating the impact of certification can be complex because of the range of factors that combine to influence fishery operations. Nonetheless, two main studies using different methodological approaches have already provided early insights into how the MSC programme leads to “change”. The studies demonstrate benefits that can be linked to certification, including specific environmental improvements, instances of progress in policy and operations and economic and social benefits. The MSC is currently developing a framework to formalize the way impacts are assessed. It is being designed to be an objective, cost-effective process that allows monitoring and evaluating trends over time. It involves selecting and testing indicators and data-monitoring tools and will incorporate significant stakeholder input to ensure credibility and relevance. In addition to ensuring accountability, an improved and more consistently applied impact assessment procedure will provide a valuable learning mechanism for continuous refinement of the MSC.

Creators: name: Shelton, Peter A.
Publisher: name: ASC 2010 - Theme session D
Year: 2024
Subjects: Fisheries and aquaculture

description: No abstracts are to be cited without prior reference to the author.Eco-certification and eco-labelling hold the promise of augmenting traditional fishery management approaches carried out by governments and regional fishery management organizations (RFMOs) for sustainable fishery. A number of Marine Stewardship Council (MSC)-certified fisheries, however, are not in fact sustainable using commonly accepted maximum sustainable yield (MSY)-based criteria and in these cases the eco-label may be misleading the public. Eco-certification of depleted fisheries or fisheries with insufficient data to determine a sustainable fishing strategy are contributing to a weakening of the impact of the MSC brand and could diminish a valuable societal feedback mechanism to achieve truly sustainable fisheries where government and RFMO legislation and conventions have largely failed. Further complications arise because MSC certifies fisheries targeting more than one species (e.g. South African hake) or more than one stock (e.g. New Zealand hoki) where one component may be severely depleted, yet the fishery as a whole is deemed “sustainable”. Aspects of MSC governance are also of concern in democratic society in which wild marine fish populations are viewed as a public asset. A secret preassessment selection process for candidate fisheries before public disclosure that a full assessment has commenced (and non-disclosure of unsuccessful preassessments), profit-maximizing strategies of a near-monopoly of consulting companies hired to do the assessment, the down-weighting of negative independent review of assessments, the costly objection process, and the legal rather than scientific objection-resolution process should all be of public concern. Rather than being universally supported by environmental groups, the MSC has been accused of lowering the bar on a number of controversial sustainability assessments in order to increase its market share and feed its expansionist aspirations, and of fostering a competitive-exclusion approach to existing credible regional or national sustainable seafood endeavours such as the Monterey Bay Aquarium Seafood Watch programme, which not only identifies the best seafood choices but also highlights those to avoid. A number of these shortcomings can be addressed, and should be, if public support for the MSC eco-label is to grow at the same rate as the number of fisheries being certified.

description: We consider large-scale service systems with multiple customer classes and multiple server pools; interarrival and service times are exponentially distributed, and mean service times depend both on the customer class and server pool. It is assumed that the allowed activities (routing choices) form a tree (in the graph with vertices being both customer classes and server pools). We study the behavior of the system under a Leaf Activity Priority (LAP) policy, which assigns static priorities to the activities in the order of sequential "elimination" of the tree leaves. We consider the scaling limit of the system as the arrival rate of customers and number of servers in each pool tend to infinity in proportion to a scaling parameter r, while the overall system load remains strictly subcritical. Indexing the systems by parameter r, we show that (a) the system under LAP discipline is stochastically stable for all sufficiently large r and (b) the family of the invariant distributions is tight on scales $r^{1/2 + ε}$ for all $ε> 0$. (More precisely, the sequence of invariant distributions, centered at the equilibrium point and scaled down by $r^{-(1/2 + ε)}$, is tight.)

description: We investigate multipartite states in the Fenna-Matthews-Olson (FMO) pigment-protein complex of the green sulfur bacteria using a Lorentzian spectral density of the phonon reservoir fitted with typical parameter estimates of the species, P. aestuarii. The evolution of the entanglement measure of the excitonic W qubit states is evaluated in the picosecond time range, showing increased revivals in the non-Markovian regime. Similar trends are observed in the evolution dynamics of the Meyer-Wallach measure of the N-exciton multipartite state, with results showing that multipartite entanglement can last from 0.5 to 1 ps, between the Bchls of the FMO complex. The teleportation and quantum information splitting fidelities associated with the GHZ and W_A resource states of the excitonic qubit channels of the FMO complex show that revivals in fidelities increase with the degree of non-Markovian strength of the decoherent environment. Results indicate that quantum information processing tasks involving teleportation followed by the decodification process involving W_A states of the FMO complex, may play a critical role during coherent oscillations at physiological temperatures.

description: No abstracts are to be cited without prior reference to the author.Certification programmes such as the Marine Stewardship Council (MSC) are continuously refining their evaluation processes, but substantial challenges remain for fishery agencies faced with the practical aspects of compiling submissions for eco-certification (fragmented information, workload, transparency). These challenges are magnified when an agency has to deal with dozens of concurrent certifications and regular recertifications in addition to the regular suite of status assessments, performance evaluations, and communication materials—all of them drawing on a lot of the same information and involving the same agency staff. Principles of industrial/organizational psychology can be applied to the task of compiling information for sustainability audits, improving both the efficiency of the process and the institutional value of the resulting documentation beyond the immediate certification requirements. We illustrate the approach with the certification of fisheries harvesting pink salmon (Oncorhynchus gorbuscha) and chum salmon (Oncorhynchus keta) in British Columbia. This process had the potential for ballooning submissions with 47 criteria evaluated for each of seven distinct certification units, for a total 329 written responses drawing from all branches of the management agency. We improved the process by redesigning the task attributes for individual contributors and reorganizing the supporting information to match the scope of related criteria clusters. For example, criteria that evaluate the regional management system rather than individual fisheries are addressed in a single regional response, which doubles as a communication resource (e.g. habitat protection measures, fleet characteristics, ecosystem research).

This situation is very different from asymptotically AdS settings where one is allowed to choose an arbitrary boundary metric. The closest one can come to changing the boundary metric in the asymptotically flat context, while maintaining the group of asymptotic symmetries to be Poincare, is to change the so-called `supertranslation frame' ω. The most studied choice corresponds to taking ω= 0. In this paper we study consequences of making alternative choices. We perform this analysis in the covariant phase space approach as well as in the holographic renormalization approach. We show that all choices for ωare allowed in the sense that the covariant phase space is well defined irrespective of how we choose to fix supertranslations. The on-shell action and the leading order boundary stress tensor are insensitive to the supertranslation frame. The next to leading order boundary stress tensor depends on the supertranslation frame but only in a way that the transformation of angular momentum under translations continues to hold as in special relativity.

description: In this paper, we propose a new multi-layer structural approach for the task of object based image retrieval. In our work we tackle the problem of structural organization of local features. The structural features we propose are nested multi-layered local graphs built upon sets of SURF feature points with Delaunay triangulation. A Bag-of-Visual-Words (BoVW) framework is applied on these graphs, giving birth to a Bag-of-Graph-Words representation. The multi-layer nature of the descriptors consists in scaling from trivial Delaunay graphs - isolated feature points - by increasing the number of nodes layer by layer up to graphs with maximal number of nodes. For each layer of graphs its own visual dictionary is built. The experiments conducted on the SIVAL and Caltech-101 data sets reveal that the graph features at different layers exhibit complementary performances on the same content and perform better than baseline BoVW approach. The combination of all existing layers, yields significant improvement of the object recognition performance compared to single level approaches.

description: No abstracts are to be cited without prior reference to the author.Tropical tuna purse-seiners catch tunas through two main strategies: they fish on free-swimming tuna schools or on fish-aggregating devices (FADs). Fishing on FADs generates some bycatch (3–5% of the tunas they land), mainly undersized tunas, other finfish (dolphinfish, triggerfish, etc.), sharks, and some rays. Both the silky (Carcharhinus falciformis) and the oceanic white tip shark (C. longimanus) are at risk from purse-seine fishing gear. Two main international research projects, collaborating together, are investigating new mitigation techniques to reduce the impact of tuna fishing on elasmobranchs: the EU FP7 MADE project (Mitigating Adverse Ecological Impacts of Open Ocean Fisheries, www.made-project.eu) and the ISSF (International Seafood Sustainability Foundation, www.iss-foundation.org) mitigation project. The general philosophy of both projects is to involve fishers in all stages of the research. We present the different research actions and present the first results of these projects. Three categories of mitigation techniques are currently investigated: (i) before fishers reach the fishing zone (identify areas with high rates of catches of sharks from observers data, design and test ecological FADs that do not cause entanglement of sharks), (ii) before or during fishing (to avoid catching elasmobranchs), and (iii) after fishing (optimizing the survival of released animals). In addition to mitigating bycatch, we also investigate whether the release of thousands of artificial FADs on the ocean affects the behaviour of sharks through electronic tagging. We discuss the pros and cons of the different approaches to mitigation of the impact of this fishery on elasmobranchs.

description: Background: The completion of an implementation research project typically signals the end of research. In contrast, the Ghana Health Service has embraced a continuous process of evidence-based programming, wherein each research episode is followed by action and a new program of research that monitors and guides the utilization of lessons learned. This paper reviews the objectives and design of the most recent phase in this process, known as a National Program for Strengthening the Implementation of the Community-based Health Planning and Services (CHPS) Initiative in Ghana (CHPS+).

Methods: A mixed method evaluation strategy has been launched involving: i) baseline and endline randomized sample surveys with 247 clusters dispersed in 14 districts of the Northern and Volta Regions to assess the difference in difference effect of stepped wedge differential cluster exposure to CHPS+ activities on childhood survival, ii) a monitoring system to assess the association of changes in service system readiness with CHPS+ interventions, and iii) a program of qualitative systems appraisal to gauge stakeholder perceptions of systems problems, reactions to interventions, and perceptions of change. Integrated survey and monitoring data will permit multi-level longitudinal models of impact; longitudinal QSA data will provide data on the implementation process.

Discussion: A process of exchanges, team interaction, and catalytic financing has accelerated the expansion of community-based primary health care in Ghana’s Upper East Region (UER). Using two Northern and two Volta Region districts, the UER systems learning concept will be transferred to counterpart districts where a program of team-based peer training will be instituted. A mixed method research system will be used to assess the impact of this transfer of innovation in collaboration with national and regional program management. This arrangement will generate embedded science that optimizes prospects that results will contribute to national CHPS reform policies and action.

description: We discuss on the possibility that colliding dark matter particles in the form of neutralinos may be gravitationally boosted near the super-massive black hole at the galactic center so that they can have enough collision energy to annihilate into a stau pair. Since in some phenomenologically favored supersymmetric models the mass splitting between the neutralino and the lightest stau, one of the two scalar superpartners of the tau lepton, is a few GeVs, this channel may be allowed. In addition, staus can only decay into a tau lepton and another neutralino. We calculate the gamma-ray spectrum and flux generated by the tau pair discussing the observability of the obtained features.

title: The spatial distribution of spiny dogfish (Squalus acanthias) in the Gulf of Alaska: the use of fishery-dependent data, fishery-independent data, and generalized modelling for the spatial management of catch and bycatch

description: No abstracts are to be cited without prior reference to the author.The spiny dogfish (Squalus acanthias) is a common bycatch species in commercial longline fisheries in the Gulf of Alaska. This small shark is widely considered as a nuisance and most dogfish bycatch is discarded. Their spatial distribution in the Gulf of Alaska is poorly understood. A better understanding of areas of high bycatch would provide critical information to fishery managers, whether they seek to convert discards into valuable fishery landings or whether they seek to reduce fishing mortality on this long-lived species. We analysed the spatial distribution of spiny dogfish from fishery and survey data collected between 1996 and 2008 using generalized additive and generalized linear modelling techniques. Poisson, negative binomial, and quasi-Poisson error structures were investigated using goodness-of-fit statistics. The quasi-Poisson generalized additive model provided the best fit for predicting counts of dogfish and accommodating overdispersion caused by areas with low dogfish counts. The results revealed catches of spiny dogfish were concentrated east of Kodiak Island, Alaska, with a general shift in the distribution of dogfish to the west of Kodiak Island between 1996 and 2008. Greater bottom depth and fishing effort led to a non-linear decrease in dogfish catch over the period examined. In contrast to common perception among the Alaskan fishing industry, results do not suggest a large increase in the dogfish population in the Gulf of Alaska in recent years. Furthermore, modelling results reveal areas of high dogfish density that indicate core areas that are important to future stock assessments and management of harvest and bycatch.

description: Barnard College has a nationally recognized dance department, and library administrators in collaboration with faculty piloted media and digital tools for dance research, performance, and composition. This chapter highlights three projects: the use of an augmented reality (AR) app, VR/360 video, and long-exposure LED photography as it relates to dance education and the performing arts at Barnard College, Columbia University. While these technologies are new and still in the exploratory stages, this descriptive case study supports the idea that AR/360 tools can offer innovative methods for the recording, scholarship, and instruction around the performing arts. These three projects were the result of a collaboration between Barnard dance faculty members and Barnard IMATS (Instructional Media and Technology Services). While each project was different in technology and scope, all three had a similar goal: to capture, represent, and experience dance in new and innovative ways. This includes a) giving audience members an opportunity to view dance pieces via an AR mobile application that also incorporated archival photographs and site-specificity; b) offering an immersive and viewer-directed method to watch dance via 360/VR video; and c) recording dance scales through time-lapse technology, representing movement through an original method. All three projects have implications for dance education and scholarship.
