description: NGC 6822 is the closest isolated dwarf irregular galaxy to the Milky Way. Its proximity and stellar mass ($10^8 M_\odot$, large for a dwarf galaxy) allow for a detailed study of its kinematic properties. The red giant branch (RGB) stars at the galaxy's center are particularly interesting because they are aligned on an axis perpendicular to the galaxy's more extended HI disk. We detected a velocity gradient among the RGB population using spectra from Keck DEIMOS. This rotation is aligned with the HI disk, but the sense of rotation is about the major axis of the central RGB population. We measured the rotation velocity ($v$) and velocity dispersion ($σ$) of the RGB population in five metallicity bins. We found an increase of rotation support ($v/σ$) with increasing metallicity, driven primarily by decreasing dispersion. We also deduced an increasing radial distance for lower metallicity stars at $-0.5$~kpc/dex by relating the observed stellar kinematics to position via NGC 6822's HI velocity curve. While the inverted metallicity gradient-like could be interpreted as evidence for an outside-in formation scenario, it may instead indicate that stellar feedback disturbed a centrally star forming galaxy over time.

description: We consider an Ising competitive model defined over a triangular Husimi tree where loops, responsible for an explicit frustration, are even allowed. After a critical analysis of the phase diagram, in which a ``gas of non interacting dimers (or spin liquid) - ferro or antiferromagnetic ordered state'' transition is recognized in the frustrated regions, we introduce the disorder for studying the spin glass version of the model: the triangular +/- J model. We find out that, for any finite value of the averaged couplings, the model exhibits always a phase transition, even in the frustrated regions, where the transition turns out to be a glassy transition. The analysis of the random model is done by applying a recently proposed method which allows to derive the upper phase boundary of a random model through a mapping with a corresponding non random one.

Insights from the inside : practitioner perspectives on planning
Creators: name: Lewis, Christine Harumi
Publisher: name: University of British Columbia
Year: 2009

description: This interpretive study was designed to learn more about program planning from the practitioner's perspective, to understand how those directly involved in planning make sense of thenwork. Of particular interest was practitioner experience in non-formal educational settings where education is not the primary purpose. Six practitioners responsible for planning health promotion programs in hospitals and public health departments participated in three in-depth interviews. Findings in three thematic areas were analyzed using insights from two frame perspectives (Elgstrom & Riis, 1992; Schon & Rein, 1994): Language and metaphors of practice: Practitioners' comments reflected more the uncertain, dynamic environment of planning, and the people-orientation of their work, and less the technical-rational approach to planning Practitioner metaphors embed organizational and societal values. As metaphors both reflect and shape practice, we begin to understand how we socially and politically frame and construct our experiences. Factors influencing practice: Practitioners identified three key frame factors: the understanding of the program concept itself, in this case, health promotion; senior management commitment and direction; and the support and involvement of colleagues. These factors may be viewed as negotiable or non-negotiable depending on the individual practitioner. Professional performance: Practitioner roles and strategies reflected the people-work of practice: communicating, coordinating, negotiating to maintain support for the program Skills in such areas as group process, conflict resolution and consensus-building are key to effective practice. Situated frame reflection with colleagues within the immediate context of practice and at different levels of action frames (program, organizational and societal) may broaden the practitioner's awareness of the assumptions and implications of planning. The study affirms the social interactive nature of program planning currently portrayed in the literature and points out several key implications. By attending to how practitioners frame and act on planning challenges, by expanding the language of planning to reflect practitioner experience, by developing relevant curriculum for the interpersonal people work of practice, and by examining the ethical base of practice and its micro-macro level implications-- we may work toward development of planning theories which better reflect the richness and complexity of practice.

description: We show that the Dirac operator on a spin manifold does not admit $L^2$ eigenspinors provided the metric has a certain asymptotic behaviour and is a warped product near infinity. These conditions on the metric are fulfilled in particular if the manifold is complete and carries a non-complete vector field which outside a compact set is gradient conformal and non-vanishing.

description: We study many-body localization (MBL) in a pair-hopping model exhibiting strong fragmentation of the Hilbert space. We show that several Krylov subspaces have both ergodic statistics in the thermodynamic limit and a dimension that scales much slower than the full Hilbert space, but still exponentially. Such a property allows us to study the MBL phase transition in systems including more than $50$ spins. The different Krylov spaces that we consider show clear signatures of a many-body localization transition, both in the Kullback-Leibler divergence of the distribution of their level spacing ratio and their entanglement properties. But they also present distinct scalings with system size. Depending on the subspace, the critical disorder strength can be nearly independent of the system size or conversely show an approximately linear increase with the number of spins.

description: Objective: To explore whether feeding only directly from the breast in the first 24-48 h of life increases the proportion of infants receiving any breast milk at 6 months. Design: A prospective cohort study. Setting: Three maternity hospitals in Melbourne, Australia. Participants: 1003 postpartum English-speaking women with a healthy singleton term infant, who intended to breast feed, were recruited between 2009 and 2011. Women were excluded if they or their infant were seriously ill. 92% (n=924) were followed up at 6 months postpartum. Primary and secondary outcome measures: Main exposure variable - type of infant feeding in hospital up to time of study recruitment (24-48 h postpartum), categorised as 'fed directly at the breast only' or 'received at least some expressed breast milk (EBM) or infant formula'. Primary outcome - proportion of infants receiving any breast milk feeding at 6 months postpartum. Secondary outcomes - proportion of infants receiving only breast milk feeding at 6 months; breast milk feeding duration; and maternal characteristics associated with giving any breast milk at 6 months. Results: Infants who had fed only at the breast prior to recruitment were more likely to be continuing to have any breast milk at 6 months than those who had received any EBM and/or infant formula (76% vs 59%; adjusted OR 1.76, 95% CI 1.24 to 2.48 (adjusted for parity, type of birth, breastfeeding intention, breastfeeding problems at recruitment, public/private status, epidural for labour or birth, maternal body mass index and education)). Conclusions: Healthy term infants that fed only directly at the breast 24-48 h after birth were more likely to be continuing to breast feed at 6 months than those who received any EBM and/or formula in the early postpartum period. Support and encouragement to initiate breastfeeding directly at the breast is important.

description: In the last few years, the low-momentum nucleon-nucleon (NN) interaction V-low-k derived from free-space NN potentials has been successfully used in shell-model calculations. V-low-k is a smooth potential which preserves the deuteron binding energy as well as the half-on-shell T-matrix of the original NN potential up to a momentum cutoff Lambda. In this paper we put to the test a new low-momentum NN potential derived from chiral perturbation theory at next-to-next-to-next-to-leading order with a sharp low-momentum cutoff at 2.1 fm-1. Shell-model calculations for the oxygen isotopes using effective hamiltonians derived from both types of low-momentum potential are performed. We find that the two potentials show the same perturbative behavior and yield very similar results.

description: The PARCEDES project funded by the French National Research Agency (ANR) involve multiple institutions across France, Italy, and England and aim to study the organization and evolution of agrarian parcels or field boundaries from Protohistory to the present day in four different areas (Vend.e, N.mes, Maremma, Devon) in order to identify local particularities and general scenarios for the evolution of agrarian parcels. The project has a strong digital component, which complies as closely as possible with the FAIR principles, using a number of French digital tools, some of which are supported by the French government.

Since 2023, several actions have been undertaken to give access to an visualise certain data produced or used during the project and to promote the research carried out within the project:

- the production of webGIS with ArcGis online for public access enabling the display of datasets (https://parcedes. hypotheses.org/category/webgis);

- the storage and sharing of data sets on the “Fabrique Num.rique du Pass.. (https://www.fabriquenumeriquedupasse.fr/pages/homepage_v2/) dedicated to the storage and dissemination ofgeohistorical data, backed by the “Projects Time Machine” consortium of the IR* Huma-Num (French State Research Infrastructure) https://parcedes.hypotheses.org/1155);

- the ongoing publication of data papers on certain datasets produced by ANR PARCEDES;

- promoting the results of PARCEDES research in the form of StoryMaps (https://parcedes.hypotheses.org/984)

The challenges outlined in the paper, such as the fragmented landscape of data sharing, lack of standards, and obstacles in feeding data into research infrastructures, highlight the importance of initiatives like PARCEDES. By addressing these challenges, the project contributes to facilitating data sharing in archaeology and ensuring the long-term preservation of valuable geohistorical information. The guidelines and actions proposed in the paper align with the goals of collaborative projects like PARCEDES in creating a more accessible and interoperable geohistorical data.

description: Imparting and maintaining surface superhydrophobicity is receiving significant research attention over the last several years, driven by a broad range of important applications and enabled by advancements in materials and surface nanoengineering. Researchers have investigated the effect of temperature on droplet-surface interactions, which poses additional challenges when liquid nucleation manifests itself, due to ensuing condensation into the surface texture that compromises its anti-wetting behavior. Maintaining surface transparency at the same time poses an additional and significant challenge. Often, the solutions proposed are limited by working temperatures or are detrimental to visibility through the surface. Here we introduce a scalable method employing plasmonic photothermal metasurface composites, able to harvest sunlight and naturally heat the surface, sustaining water repellency and transparency under challenging environmental conditions where condensation and fogging would otherwise be strongly promoted. We demonstrate that these surfaces, when illuminated by sunlight, can prevent impalement of impacting water droplets, even when the droplet to surface temperature difference is 50°C, by suppressing condensate formation within the texture, maintaining transparency. We also show how the same transparent metasurface coating could be combined and work collaboratively with hierarchical micro- and nanorough textures, resulting in simultaneous superior pressure-driven impalement resistance and avoidance of water nucleation and related possible frosting in supercooled conditions. Our work can find a host of applications as a sustainable solution against impacting water on surfaces such as windows, eyewear, and optical components.

Clustering

description: As the threat of climate change grows alongside a continual increase in urban population, the need to ensure access to water and energy resources becomes more crucial. In the context of the water-energy nexus in urban environments, this work addresses current gaps in understanding of coupled water and energy demand patterns and reveals apparent dissimilarities between utilization of water and energy resources for heterogeneous buildings. This study proposes a data-driven approach to identify fundamental water and energy demand profiles, cluster buildings into groups exhibiting similar water and energy use, and predict their demand. The clustering problem was cast as a two-stage cluster ensemble problem, in which several clustering methods with different settings were employed, and then the results obtained from partial view of the data were combined to achieve consensus among the partitionings. The influential drivers for water and energy consumption were identified, parametric and non-parametric prediction models were developed and compared, utilizing high and low temporal data resolution. The clustering analysis performed in this work revealed that water and energy consumption patterns of heterogeneous buildings are not exclusively characterized by general building characteristics. Analysis of the predictive models showed that an overall non-parametric model provides better predictions for water and energy compared with parametric models and that models with high and low data resolution provide comparable demand predictions. The results of this study highlight the value of data-driven modeling for revealing meaningful insights into usage patterns and benchmarking buildings’ performance to provide a meaningful measure of comparison to facilitate multi-utility management. Overall, the methods outlined in this study provide another step towards building greater resiliency within urban areas in preparation for future changes in population and climate

description: Third-order statistics of the cosmic density field provides a powerful cosmological probe containing synergistic information to the more commonly explored second-order statistics. Here, we exploit a spectroscopic catalog of 72,563 clusters of galaxies extracted from the Sloan Digital Sky Survey, providing the first detection of the baryon acoustic oscillations (BAO) peak in the three-point correlation function (3PCF) of galaxy clusters. We measure and analyze both the connected and the reduced 3PCF of SDSS clusters from intermediate ($r\sim10$ Mpc/h) up to large ($r\sim140$ Mpc/h) scales, exploring a variety of different configurations. From the analysis of reduced 3PCF at intermediate scales, in combination with the analysis of the two-point correlation function, we constrain both the cluster linear and non-linear bias parameters, $b_1=2.75\pm0.03$ and $b_2=1.2\pm0.5$. We analyze the measurements of the 3PCF at larger scales, comparing them with theoretical models. The data show clear evidence of the BAO peak in different configurations, which appears more visible in the reduced 3PCF rather than in the connected one. From the comparison between theoretical models considering or not the BAO peak, we obtain a quantitative estimate of this evidence, with a $Δχ^2$ between 2 and 75, depending on the considered configuration. Finally, we set up a generic framework to estimate the expected signal-to-noise ratio of the BAO peak in the 3PCF exploring different possible definitions, that can be used to forecast the most favorable configurations to be explored also in different future surveys, and applied it to the case of the Euclid mission.

Postmodern refections[sic] for marine safety education on "tin boating" in the Canadian wilderness
Creators: name: Rosenthal, Alex
Publisher: name: University of British Columbia
Year: 2009

description: Marine safety education initiatives are most often constructed along rational functionalist lines that tend to assume that accidents and deaths that accompany them are caused by lack of appropriate technical knowledge, equipment failure or the irrational behaviour of participants. One sector identified by this research, which seems to have a disproportionally high rate of involvement in these incidents, is that of small open skiffs < 5.5m - usually made from aluminum. Most of these incidents take place on the inland waterways of the Canadian Shield. I look at the activity from the perspective of two separate but parallel discourses on the topic: the official discourse as portrayed by the Canadian Coast Guard, Search and Rescue, the Power and Sail Squadrons, the Canadian Red Cross and various police forces and the popular discourse as seen in lifestyle commercials, advertising catalogues, outdoors sporting goods shows and sports television. I suggest throughout that gender, race and economic marginality are powerful influences that must be factored into our educative efforts if we, the Canadian boating public, are to reduce the number of fatalities. The construction of the subjectivites of the participants will be considered in the context of several competing conceptions concerning the nature of Nature in the postmodern era. A form of narrative analysis known as deconstruction is used to interrogate the theoretical foundations of the textual artefacts. I use postcolonial theory to develop a distinctively Canadian narrative concerning the underpinnings of a reconceptualized marine safety education. In the final section, some considerations for extending this work into other areas of wilderness recreation were explored.

Then we find the deflection angle by Casimir wormhole in weak field limits. Moreover, we obtain the weak deflection angle in the presence of plasma medium and see the effect of the plasma medium on the weak deflection angle. Moreover, we study a shadow of Casimir wormhole and we plot and discuss them. We show the shadow of Casimir wormhole's behavior when changing the value of $a$.

description: We propose a new potential in brane inflation theory, which is given by the arctangent of the square of the scalar field. Then we perform an explicit computation for inflationary quantities. This potential has many nice features. In the small field approximation, it reproduces the chaotic and MSSM potentials. It allows one, in the large field approximation, to implement the attractor mechanism for bulk black holes where the geometry on the brane is de Sitter. In particular, we show, up to some assumptions, that the Friedman equation can be reinterpreted as a Schwarzschild black hole attractor equation for its mass parameter.

description: Full-band atomistic quantum transport simulations based on first principles are employed to assess the potential of band-to-band tunneling FETs (TFETs) with a 2-D channel material as future electronic circuit components. We demonstrate that single-layer (SL) transition metal dichalcogenides are not well suited for TFET applications. There might, however, exist a great variety of 2-D semiconductors that have not even been exfoliated yet; this paper pinpoints some of the most promising candidates among them to realize highly efficient TFETs. SL SnTe, As, TiNBr, and Bi are all found to ideally deliver ON-currents larger than 100μA/μm at 0.5-V supply voltage and 0.1 nA/μm OFF-current value. We show that going from single to multiple layers can boost the TFET performance as long as the gain from a narrowing bandgap exceeds the loss from the deteriorating gate control. Finally, a 2-D van der Waals heterojunction TFET is revealed to perform almost as well as the best SL homojunction, paving the way for research in optimal 2-D material combinations.

description: We present a domain decomposition approach for the computation of the electromagnetic field within periodic structures. We use a Schwarz method with transparent boundary conditions at the interfaces of the domains. Transparent boundary conditions are approximated by the perfectly matched layer method (PML). To cope with Wood anomalies appearing in periodic structures an adaptive strategy to determine optimal PML parameters is developed. We focus on the application to typical EUV lithography line masks. Light propagation within the multi-layer stack of the EUV mask is treated analytically. This results in a drastic reduction of the computational costs and allows for the simulation of next generation lithography masks on a standard personal computer.

description: The assessment of an intersection, appears to be as important as designing properly the whole road. Roundabouts is a common form of intersection, used extensively worldwide. Roundabouts have been used successfully in many cases throughout the world. They offer a proven form of traffic control and there are many locations that could benefit from the installation of a roundabout as an alternative to the more conventional intersection control methods such as stop signs and traffic signals. The safe and efficient manner in which they accommodate traffic, in addition to their improved aesthetics, have focused a strong attention on roundabouts as an important element in the design of state and local roadways. Recognizing a strong interest in roundabouts throughout the world, engineering society launches research projects to develop guidelines to assist operating agencies with decisions regarding roundabout design and implementation. This thesis is a research that describes, implements and finally launches a method for the assessment of modern roundabouts. Specifically, analyses all sectors and parameters related to the different categories of roundabouts.For the completion of this analysis, the evaluating checklist is applied to an existent double roundabout at the outskirts if the city of Aridaia - Municipality of Pella. The results of the evaluation show the efficiency of the proposed method.

description: The primary aim of this cumulative work is to examine how individuals mentally represent the relationships between subjective vitality, motivation to conserve energy, and motivation for cognitive effort. While validated German self-report measures for subjective vitality exist, no scales currently assess motivation to conserve energy or momentary motivation for cognitive effort. To address this gap, we developed and validated two self-report scales: the Motivation for Cognition Scale (MFC), which assesses motivation for cognition as a state (Study 1), and the Conservation of Human Energy Resources Index (CHERI), which measures motivation to conserve energy (Study 2). These measures were subsequently applied in a randomized control trial using experimental vignettes (Study 3), revealing that participants associate lower subjective vitality with greater motivation to conserve energy and reduced motivation for cognitive effort. Conversely, higher subjective vitality was linked to decreased motivation to conserve energy and greater motivation for cognitive effort. We discuss the significance of these findings for schema-based approaches, with a particular focus on understanding self-control failure.

description: The strong photon-magnon coupling between an electromagnetic cavity and two yttrium iron garnet (YIG) spheres has been investigated in the context of a strong mutual dipolar interaction between the spheres. A decrease in the coupling strength between the YIG spheres and the electromagnetic cavity is observed, along with an increase of the total magnetic losses, as the distance between the spheres is decreased. A model of inhomogeneous broadening of the ferromagnetic resonance linewidth, partly mitigated by the dipolar narrowing effect, reproduces the reduction in the coupling strength observed experimentally. These findings have important implications for the understanding of strongly coupled photon-magnon system involving densely packed magnetic objects, such as ferromagnetic nanowires arrays, in which the total coupling strength with an electromagnetic cavity might become limited due to mutual dipolar interactions.

description: Burst swimming performance in fishes is relatively understudied despite its critical role in predation attempts and prey evasion, spawning events, and passing hydraulic challenges. Burst swimming is characterized by fast acceleration, over a short distance and of limited duration. The bulk of fast-start performance research uses analysis of high-speed recordings of fish behavior. While behavioral video analysis has improved, it is still expensive in both processing time and computational resources. Here we introduce a laser-gated burst tunnel that improved upon past designs by introducing an adjustable number of lasers (≤ 25) that facilitated greater resolution on burst performance as well as novel laser arrangements facilitating novel performance metrics (e.g., fatigue rate, burst capacity). We quantified the burst velocity, burst capacity and fatigue rate of rainbow trout (Oncorhynchus mykiss), a widely distributed and studied species. We directly compared the results measured by our device to simultaneously collected high-speed camera data and find the velocity estimates to be highly accurate (R2 = 0.97). We also compared the burst performance of individual rainbow trout with their individual UCRIT, a commonly measured metric of aerobic swimming performance. We found little correlation between the two traits, indicating that fish capable of rapid burst swimming are not necessarily fast sustained swimmers. Finally, we defined and quantified two novel traits of burst swimming performance: burst capacity (the number of burst events that can be elicited prior to performance decline), and fatigue rate (the rate of decline associated with repeated bursting). The burst tunnel is an adjustable platform for quantifying understudied elements of fish swimming physiology, improving design of fish passage technology, and facilitating discoveries in how burst swimming performance changes with environmental conditions.

description: We present a systematic analysis of the extended X-ray emission discovered around 35 FR II radio galaxies from the revised Third Cambridge catalog (3CR) Chandra Snapshot Survey with redshifts between 0.05 to 0.9. We aimed to (i) test for the presence of extended X-ray emission around FR II radio galaxies, (ii) investigate if the extended emission origin is due to Inverse Compton scattering of seed photons arising from the Cosmic Microwave Background (IC/CMB) or to thermal emission from an intracluster medium (ICM) and (iii) test the impact of this extended emission on hotspot detection. We investigated the nature of the extended X-ray emission by studying its morphology and compared our results with low-frequency radio observations (i.e., $\sim$150 MHz), in the TGSS and LOFAR archives, as well as with optical images from Pan-STARRS. In addition, we optimized a search for X-ray counterparts of hotspots in 3CR FR II radio galaxies. We found statistically significant extended emission ($>$3$σ$ confidence level) along the radio axis for $\sim$90%, and in the perpendicular direction for $\sim$60% of our sample. We confirmed the detection of 7 hotspots in the 0.5 - 3 keV. In the cases where the emission in the direction perpendicular to the radio axis is comparable to that along the radio axis, we suggest that the underlying radiative process is thermal emission from ICM. Otherwise, the dominant radiative process is likely non-thermal IC/CMB emission from lobes. We found that non-thermal IC/CMB is the dominant process in $\sim$70% of the sources in our sample, while thermal emission from the ICM dominates in $\sim$15% of them.

description: The incommensurate composite systems M14Cu24O41 (M=Ca,Sr,La) are based on two fundamental structural units: CuO2 chains and Cu2O3 ladders. We present electronic structure calculations within density functional theory in order to address the interrelations between chains and ladders. The calculations account for the details of the crystal structure by means of a unit cell comprising 10 chain and 7 ladder units. It turns out that chains and ladders can be treated independently, which allows us to introduce a model system based on a reduced unit cell. For the CuO2 chains, we find two characteristic bands at the Fermi energy. Tight binding fits yield nearest and next-nearest neighbour interactions of the same order of magnitude.

description: It is an open question to give a combinatorial interpretation of the Falk invariant of a hyperplane arrangement, i.e. the third rank of successive quotients in the lower central series of the fundamental group of the arrangement. In this article, we give a combinatorial formula for this invariant in the case of hyperplane arrangements that are complete lift representation of certain gain graphs. As a corollary, we compute the Falk invariant for the cone of the braid, Shi, Linial and semiorder arrangements.

description: This article presents and discusses some theses elaborated by Emanuele Coccia in his recent book The life of Plants. A theme that seemed abandoned to the margins of philosophical conceptuality, the idea of nature, and in particular the idea of plant life, seems to have acquired a renewed interest by philosophers in recent times. Starting from the radical rethinking of some metaphysical categories (subject, object, immersion, life, form), the article discusses the possibility of giving back to the philosophy of nature the importance it deserves. As the book, the article closes with a reflection on the role of philosophy in the future university.

Women creating a caring organization : the public dimensions of care
Creators: name: Smith, Linette Wright
Publisher: name: University of British Columbia

description: The purpose of this ethnographic study is to describe and illustrate how the Board members of a nonprofit organization have constructed and sustained a caring organization. The study answers the ethnographic questions that framed the research purpose and focus: What are the organization's core values? Where, when, how and by whom are they articulated? How do the participants enact these core values in their practice? What is the role of learning in a caring organization? What does care look like in a caring organization? The focus of this study's description and analysis are the interactions and practices of the women trustees as they engaged in the work of governance within routine Board of Directors' meetings. The data collected include field observations of Board meetings, interviews with Board members and organizational documents. The study conceptualizes meetings as the primary process and form in which organizational members create, maintain, and re-create their organization (Schwartzman, 1989). The study uses a multi-perspective approach (J. Martin, 1992) to organizational culture in order to describe elements of congruence, difference and contradiction in a caring organization. The study describes and illustrates how the organizational members developed care as a central organizing principle, a moral practice and a political idea (Tronto, 1993). The members' values, beliefs, and practices had moved care from the private realms of caring work into the public realms of caring practice, expanding care from its predominantly private interpretation to a larger public notion. The organization studied was one that was founded by women, governed by women and predominantly staffed by women. It provides programs, services and resources to meet the child care needs of families, children, child care providers, child care related organizations and the community. The study's findings have implications for practice in the development of nonprofit organizations that support caring practice and caring work.

description: Suppose we are given two probability measures on the set of one-way infinite finite-alphabet sequences and consider the question when one of the measures predicts the other, that is, when conditional probabilities converge (in a certain sense) when one of the measures is chosen to generate the sequence. This question may be considered a refinement of the problem of sequence prediction in its most general formulation: for a given class of probability measures, does there exist a measure which predicts all of the measures in the class? To address this problem, we find some conditions on local absolute continuity which are sufficient for prediction and which generalize several different notions which are known to be sufficient for prediction. We also formulate some open questions to outline a direction for finding the conditions on classes of measures for which prediction is possible.
