Exploring Science Curriculum Emphases in Relation to the Alberta Physics Program-of-Study

description: Using Roberts’ (1982, 1988, 1995, 1998, 2003) seven science curriculum emphases as its framework, this investigation into Alberta’s physics program-of-study found that pre-service and novice teachers reported focusing on four of the emphases—Structure of Science; Scientific Skill Development; Science, Technology, and Decisions; and Correct Explanation— while experienced teachers reported focusing on two of the emphases—Structure of Science and Everyday Coping. Other program-of-study aspects that were reported by teachers as being of high priority included holistic views of physics and student engagement, both of which fall beyond Roberts’ framework. Teacher participants focused on different aspects of the program-of-study as compared to a senior curriculum leader in Alberta (i.e., the program manager for secondary sciences in the Curriculum Branch of Alberta Education), suggesting a possible need for professional development for teachers to deliver the program-of-study as intended by Alberta Education. This research increases understanding of how teachers interpret a physics program-of-study with respect to science curriculum emphases. Reprenant comme cadre l'accent que met Roberts sur un programme d'études reposant sur sept priorités en sciences (1982, 1988, 1995, 1998, 2003), cette recherche du programme d'études en physique de l'Alberta a trouvé que les stagiaires et les enseignants débutants se concentraient sur quatre des priorités - La structure de la science; Le développement des habiletés en science; La science, la technologie et les décisions; et La bonne explication - alors que les enseignants plus expérimentés misaient deux des priorités - La structure de la science et Pour faire face au quotidien. Parmi d'autres aspects du programme d'études que les enseignants ont évoqués comme étant prioritaires notons des perspectives holistiques de la physique et l'implication des élèves, deux composantes qui ne sont pas inclues le cadre de Roberts. Les enseignants participants ont misé différents aspects du programme d'études par rapport au chef sénior du programme d'études (c'est-à-dire le gestionnaire de programme des sciences au secondaire de la Direction des programmes d'études de Alberta Education), ce qui donne à penser qu'il pourrait avoir un besoin de développement professionnel pour que les enseignants mettent en œuvre le programme d'études tel que prévu par Alberta Education. Cette recherche vient ajouter à nos connaissances sur l'interprétation que font les enseignants du programme d'études en physique relativement aux priorités en sciences.

description: Digital modeling of the microstructure is important for studying the physical and transport properties of porous media. Multiscale modeling for porous media can accurately characterize macro-pores and micro-pores in a large-FoV (field of view) high-resolution three-dimensional pore structure model. This paper proposes a multiscale reconstruction algorithm based on multiple dictionaries learning, in which edge patterns and micro-pore patterns from homology high-resolution pore structure are introduced into low-resolution pore structure to build a fine multiscale pore structure model. The qualitative and quantitative comparisons of the experimental results show that the results of multiscale reconstruction are similar to the real high-resolution pore structure in terms of complex pore geometry and pore surface morphology. The geometric, topological and permeability properties of multiscale reconstruction results are almost identical to those of the real high-resolution pore structures. The experiments also demonstrate the proposal algorithm is capable of multiscale reconstruction without regard to the size of the input. This work provides an effective method for fine multiscale modeling of porous media.

description: We designed and built a reduced-scale model experiment to study the paragliding inflation and launching phase at given traction force. We show that the launch trajectory of a single skin glider is universal, that is, independent of the exerted force. As a consequence, the length of the take-off run required for the glider to reach its "ready to launch" vertical position is also universal. We successfully compare our results to full-scale experiments, and show that such universality can be understood through a simple theoretical model.

description: Strong zero modes (SZMs) are conserved operators localised at the edges of certain quantum spin chains, which give rise to long coherence times of edge spins. Here we define and analyse analogous operators in one-dimensional classical stochastic systems. For concreteness, we focus on chains with single occupancy and nearest-neighbour transitions, in particular particle hopping and pair creation and annihilation. For integrable choices of parameters we find the exact form of the SZM operators. Being in general non-diagonal in the classical basis, the dynamical consequences of stochastic SZMs are very different from those of their quantum counterparts. We show that the presence of a stochastic SZM is manifested through a class of exact relations between time-correlation functions, absent in the same system with periodic boundaries.

description: This paper presents a new approach to predict the occupancy for building energy systems (BES). A Gaussian Process (GP) is used to model the occupancy and is represented as a state space model that is equivalent to the full GP if Kalman filtering and smoothing is used. The combination of GPs and mechanistic models is called Latent Force Model (LFM). An LFM-based model predictive control (MPC) concept for BES is presented that benefits from the extrapolation capability of mechanistic models and the learning ability of GPs to predict the occupancy within the building. Simulations with EnergyPlus and a comparison with real-world data from the Bosch Research Campus in Renningen show that a reduced energy demand and thermal discomfort can be obtained with the LFM-based MPC scheme by accounting for the predicted stochastic occupancy.

Loving and Loathing Physical Education: An Exploration of Students’ Beliefs
Creators: name: Robinson, Daniel B.
Publisher: name: Alberta Journal of Educational Research
Year: 2012

description: This article describes a recent study that investigated the physical education (PE) beliefs of a particular population of students (i.e., female and male students in Grades 4 through 10 from a single school stream). Through their completion of an adapted survey, students (N = 506) were able to share their PE beliefs in relation to five separate subscales: PE Interest, PE Status, PE Connotations, PE Teachers, and PE Curriculum. Results suggest that grade and gender differences exist with respect to these subscales. Consequently, it is herein suggested that the discovery of such differences within this case study merits considerations for educational change, as well as continued and deeper inquiries into understanding the nature of PE beliefs for female and male students in various grade levels. Cet article décrit une étude récente qui a porté sur les croyances qu'a une population particulière d'élèves (c.-à-d. filles et garçons, de la 4e à la 10e année, d'une école à voie unique) par rapport à l'éducation physique. Par le biais d'une enquête adaptée, les élèves (N = 506) ont partagé leurs croyances sur l'éducation physique en fonction de cinq sous-échelles séparées: intérêt, statut, sens affectifs, enseignants et curriculum. Les résultats donnent à penser qu'il existe, par rapport à ces sous-échelles, des différences liées à l'année scolaire et au genre. On propose donc que les différences révélées par cette étude de cas méritent d'être considérées dans le contexte de changements pédagogiques et d'être étudiées en profondeur et à long terme pour comprendre la nature des croyances d'élèves, filles et garçons et à divers années scolaires, relatives à l'éducation physique.

description: Cosmogenic neutrinos originate from photo-hadronic interactions of cosmic ray protons with the cosmic microwave background (CMB). The neutrino production rate can be constrained through the accompanying electrons, positrons and gamma-rays that quickly cascade on the CMB and intergalactic magnetic fields to lower energies and generate a gamma ray background in the GeV-TeV region. Bethe-Heitler pair production by protons also contributes to the cascade and can tighten the neutrino constraints in models where extragalactic cosmic rays begin to dominate over the galactic component at a relatively low "crossover" energy. We investigate this issue in the light of the recent Fermi-LAT measurements of the diffuse extragalactic gamma ray background and illustrate by a fit to the HiRes spectrum how the prediction of the cosmogenic neutrino flux in all-proton models varies with the crossover energy. The neutrino flux is required to be smaller when the gamma-ray bound is applied, nevertheless such models are still consistent with HiRes and Fermi-LAT if one properly takes into account the energy uncertainty of cosmic ray measurements. The presently allowed flux is within reach of the IceCube neutrino telescope and other dedicated radio experiments.

description: Since linear-optical two-photon gates are inherently probabilistic, measurement-based implementations are particularly well suited for photonic platforms: a large highly-entangled photonic resource state, called a graph state, is consumed through measurements to perform a computation. The challenge is thus to produce these graph states. Several generation procedures, which use either interacting quantum emitters or efficient spin-photon interface, have been proposed to create these photonic graph states deterministically. Yet, these solutions are still out of reach experimentally since the state-of-the-art is the generation of a linear graph state. Here, we introduce near-deterministic solutions for the generation of graph states using the current quantum emitter capabilities. We propose hybridizing quantum-emitter-based graph state generation with all-photonic fusion gates to produce graph states of complex topology near-deterministically. Our results should pave the way towards the practical implementation of resource-efficient quantum information processing, including measurement-based quantum communication and quantum computing.

description: Reasoning about security properties involves reasoning about where the information of a system is located, and how it evolves over time. While most security analysis techniques need to cope with some notions of information locality and knowledge propagation, usually they do not provide a general language for expressing arbitrary properties involving local knowledge and knowledge transfer. Building on this observation, we introduce a framework for security protocol analysis based on dynamic spatial logic specifications. Our computational model is a variant of existing pi-calculi, while specifications are expressed in a dynamic spatial logic extended with an epistemic operator. We present the syntax and semantics of the model and logic, and discuss the expressiveness of the approach, showing it complete for passive attackers. We also prove that generic Dolev-Yao attackers may be mechanically determined for any deterministic finite protocol, and discuss how this result may be used to reason about security properties of open systems. We also present a model-checking algorithm for our logic, which has been implemented as an extension to the SLMC system.

Regulating smart devices in restricted spaces
Creators: name: Kim, Daeyoung
Publisher: name: No Publisher Supplied
Year: 2019

description: Smart devices have spread everywhere in our daily lives, and the capabilities of smart devices equipped with a variety of sensors and peripherals are increasing. However, these devices can possibly be misused in various environments. For instance, sensitive data in enterprises and federal offices can be leaked by the use of cameras and microphones on smart devices. In classrooms, students can obtain unauthorized information during exams. Moreover, smart devices can be used to take pictures or record videos without permissions in less stringent environments such as gym locker rooms and movie theaters. Therefore, we need methods to prevent these situations instead of ad hoc methods in such restricted spaces. In this dissertation, we focus on how to regulate smart devices in restricted spaces. We propose ARM  TrustZone-based solutions to enforce policies on smart devices. In particular, the dissertation makes the following two contributions. First, we present a systematic approach for restricted space hosts to analyze and regulate guest devices using remote memory operations in the restricted space. In our approach, hosts’ policies are enforced by a small trusted computing base that executes on the guest devices. We also show that our approach provides strong security guarantees by leveraging the ARM TrustZone. Second, we propose ForceDroid, a policy enforcement system that provides a higher-level abstraction in the restricted spaces. We leverage Security-Enhanced Linux in Android (SEAndroid) to support fine-grained access control, and use Near field communication (NFC) to securely communicate between guests and hosts. In ForceDroid, predefined policies on guest devices are enforced by hosts’ requests.
Rural and Urban Teaching Experiences: Narrative Expressions
Creators: name: Preston, Jane P.
Publisher: name: Alberta Journal of Educational Research
Year: 2012

description: This qualitative exploration of rural and urban teaching experiences encapsulates the experiences of 8 Western Canadian teachers. A literature review outlines the benefits and challenges of rural and urban education. Stemming from narrative inquiry data, I present the study’s results in the form of two composite stories, which depict the lived experiences particular to rural and urban teachers. Overarching themes emanating from these stories show that rural schools nurture close teacher-student-community relationships, while urban schools serve a larger, culturally-diverse student populace. Theoretical aspects of the study include the notion that teacher identity is influenced by one’s rural and urban background. I suggest that through teacher mentorships programs and forms of professional development, teachers be supplied time to reflect on how their past rural and urban life experiences affect their present teaching attitudes and behaviors. Cette exploration qualitative portant sur les expériences rurales et urbaines résume les expériences de huit enseignants dans l’Ouest canadien. Une analyse de la littérature dresse les grandes lignes en matière d'avantages et de défis liés à l’éducation en milieu rural et en milieu urbain. Puisant dans des données découlant de données d'enquêtes narratives, je présente les résultats de l’étude sous forme de deux histoires composites illustrant les expériences particulières d’enseignants en milieu rural et en milieu urbain. Des thèmes fondamentaux en ressortent et indiquent que les écoles rurales encouragent des liens serrés entre les élèves et la communauté alors que les écoles urbaines desservent une population estudiantine plus grande et diverse sur le plan culturel. Parmi les aspects théoriques de l’étude notons l’idée selon laquelle l’identité des enseignants est influencée par leurs antécédents ruraux et urbains. Je propose qu’on offre aux enseignants le temps de réfléchir sur l’impact qu'aurait leur vécu en milieu rural ou urbain sur leurs attitudes et comportements en salle de classe et qu'on le fasse par le biais de programmes de mentorat et de développement professionnel.

description: Using a sample of 102 million $Υ(1S)$ events collected with the Belle detector, we report on the first search for charge-parity-even charmonium and charmonium-like states in $Υ(1S)$ radiative decays. No significant $χ_{cJ}$ or $η_c$ signal is observed and 90% C.L. limits on $\BR(Υ(1S)\to γχ_{c0})<6.5 \times 10^{-4}$, $\BR(Υ(1S)\to γχ_{c1})<2.3\times 10^{-5}$, $\BR(Υ(1S)\to γχ_{c2})<7.6 \times 10^{-6}$, and $\BR(Υ(1S)\to γη_c)<5.7\times 10^{-5}$ are obtained. The product branching fraction limits $\BR(Υ(1S)\to γX(3872)) \BR(X(3872)\toπ^+π^-\jpsi)< 1.6 \times 10^{-6}$, $\BR(Υ(1S)\to γX(3872)) \BR(X(3872)\toπ^+π^-π^0 \jpsi)< 2.8\times 10^{-6}$, $\BR(Υ(1S)\to γX(3915)) \BR(X(3915)\toω\jpsi)< 3.0\times 10^{-6}$, and $\BR(Υ(1S)\to γY(4140)) \BR(Y(4140)\to ϕ\jpsi)<2.2\times 10^{-6}$ are obtained at the 90% C.L. Furthermore, no evidence is found for excited charmonium states below 4.8 GeV/$c^2$.

description: Der Eisenbahnbau zwischen 1887 und 1890 war sicherlich für das "Obere Donautal" eine sehr bedeutende und weitreichende Entscheidung, deren Tragweite damals nicht allen Beteiligten so recht klar war. So protestierten zum Beispiel die Bauern von Fridingen ganz energisch gegen den ihrer Meinung nach unnötigen Landverbrauch. Sie glaubten, diese Grundstücke für die Versorgung der Bevölkerung behalten zu müssen. Dass durch den Bahnbau der Bevölkerung mehr geholfen werde, war damals nicht allen zu vermitteln. Aus heutiger Sicht kann man sagen, dass die Geschichte dieser Bahn das Leben im "Oberen Donautal" sehr stark geprägt hat Anderseits zeigt es aber auch die SchnelllebigkeIt in unserer heutigen Zeit Was vor etwas mehr als hundert Jahren als große technische Leistung gepriesen wurde, wird heute nur noch mit Mühe und Not am Leben gehalten.
Anhand verschiedener Publikationen, Erinnerungen alter Fridinger, Erinnerungen ehemaliger Eisenbahnbediensteter und aus eigener Erfahrung versuche ich diese Zeit von etwa 1860 bis heute mit dem Aufstieg und dem Niedergang der Donautalbahn innerhalb eines Jahrhunderts aufzuzeigen.
Ein Beispiel sind die Schülertransporte, bei denen die Schüler von Fridingen und Buchheim mit Bussen zum Bahnhof Fridingen gebracht werden um von dort mit der Bahn nach Tuttlingen zu fahren. Mit dem Naturparkexpress, der im Sommer auf der Donautalbahn verkehrt, und dem Ringzug im Kreis Tuttlingen wird weiter versucht, die Bahn am Leben zu halten. Ob diese Entscheidungen immer wirtschaftliche Lösungen sind, mag jeder selber
beantworten. Sicher scheint aber zu sein, dass ohne diese Maßnahmen der Bahnverkehr schon ganz aufgehoben und das Donautal um eine geschichtliche Entwicklung aus dem Industriezeitalter ärmer geworden wäre.

description: Tunnel-coupled pairs of optically active quantum dots - quantum dot molecules (QDMs) - offer the possibility to combine excellent optical properties such as strong light-matter coupling with two-spin singlet-triplet ($S-T_0$) qubits having extended coherence times. The $S-T_0$ basis formed using two spins is inherently protected against electric and magnetic field noise. However, since a single gate voltage is typically used to stabilize the charge occupancy of the dots and control the inter-dot orbital couplings, operation of the $S-T_0$ qubits under optimal conditions remains challenging. Here, we present an electric field tunable QDM that can be optically charged with one (1h) or two holes (2h) on demand. We perform a four-phase optical and electric field control sequence that facilitates the sequential preparation of the 2h charge state and subsequently allows flexible control of the inter-dot coupling. Charges are loaded via optical pumping and electron tunnel ionization. We achieve one- and two-hole charging efficiencies of 93.5 $\pm$ 0.8 % and 80.5 $\pm$ 1.3 %, respectively. Combining efficient charge state preparation and precise setting of inter-dot coupling allows control of few-spin qubits, as would be required for on-demand generation of two-dimensional photonic cluster states or quantum transduction between microwaves and photons.

description: Diabetic Retinopathy (DR), an ocular complication of diabetes, is a leading cause of blindness worldwide. Traditionally, DR is monitored using Color Fundus Photography (CFP), a widespread 2-D imaging modality. However, DR classifications based on CFP have poor predictive power, resulting in suboptimal DR management. Optical Coherence Tomography Angiography (OCTA) is a recent 3-D imaging modality offering enhanced structural and functional information (blood flow) with a wider field of view. This paper investigates automatic DR severity assessment using 3-D OCTA. A straightforward solution to this task is a 3-D neural network classifier. However, 3-D architectures have numerous parameters and typically require many training samples. A lighter solution consists in using 2-D neural network classifiers processing 2-D en-face (or frontal) projections and/or 2-D cross-sectional slices. Such an approach mimics the way ophthalmologists analyze OCTA acquisitions: 1) en-face flow maps are often used to detect avascular zones and neovascularization, and 2) cross-sectional slices are commonly analyzed to detect macular edemas, for instance. However, arbitrary data reduction or selection might result in information loss. Two complementary strategies are thus proposed to optimally summarize OCTA volumes with 2-D images: 1) a parametric en-face projection optimized through deep learning and 2) a cross-sectional slice selection process controlled through gradient-based attribution. The full summarization and DR classification pipeline is trained from end to end. The automatic 2-D summary can be displayed in a viewer or printed in a report to support the decision. We show that the proposed 2-D summarization and classification pipeline outperforms direct 3-D classification with the advantage of improved interpretability.
Impact of microscreen pretreatment and biofilm photobioreactor design on efficiency of decentralized wastewater treatment
Creators: name: Roberts, James

description: Biofilm photobioreactors rely on cooperation between algae and bacteria within a single biofilm to treat wastewater. Algae growth produces oxygen, which can subsequently be utilized by aerobic bacteria to degrade organic matter and produce carbon dioxide, which is then utilized as a carbon source by algae. Due to their relatively low maintenance and energy inputs, biofilm photobioreactors could be amenable for decentralized wastewater treatment. However, the impact of biofilm photobioreactor design on treatment efficiency has received little attention. Here, it was hypothesized that open (i.e. unsealed) versus closed (i.e. sealed) photobioreactors could promote different nitrogen removal pathways by altering redox conditions throughout a diel cycle. This study explored the effect of open versus closed photobioreactor configurations on nitrogen removal and the microbial community structure in two parallel photobioreactors treating microscreened decentralized wastewater. The reactors were intermittently lit in a 16hr-8hr light-dark cycle, and operated at an HRT of 2 days and SRT of 9 days. The influent feed regime and alkalinity addition were varied over three successive 30-day experimental phases. Microscreening was an effective primary treatment step, removing 70 ± 6% (95% c.i.) of suspended solids and 39 ± 9% of COD. The photobioreactors removed 90 ± 6 % and 83 ± 3% of the remaining suspended solids and COD respectively, independent of operating conditions. Alternating oxic and anoxic conditions were observed in both reactors during the lit and unlit periods, respectively, resulting nitrification and denitrification. Optimal nitrogen removal conditions were observed under a sequencing batch feed regime with alkalinity addition. Under these conditions, TKN removal was significantly higher in the open reactor at 93 ± 5% compared to 78 ± 6% in the closed reactor due to higher rates of nitrification and N assimilation. TN removal was similar at 77 ± 9% and 76 ± 8% in the open and closed systems, respectively. The dominant bacterial genus in the reactors was Tychonema, a cyanobacteria which comprised up to 87% of 16S rRNA gene amplicon reads. Overall, this study demonstrated that nitrogen removal pathways differ significantly in open and closed photobioreactors when operated at the same COD loading rate.

description: Among the many contending theories of bullying, the widely accepted thesis known as frustration-aggression assumes that bullying is a form of aggressive behavior induced by external stress. Recently, researchers have discovered that the relationship between external stressors and bullying is sometimes moderated by internal frustration. The present investigation is an attempt to examine which of the above mechanisms can better explain female students’ bullying behaviors. Data analysis, using structural equation modeling, was based on 1,069 girls selected from 14 primary schools and 16 junior secondary schools in Shenzhen, China. The result of the analysis suggests that while bullying by girls in primary schools is directly related to external stress, bullying in secondary schools is moderated by internal frustration. The authors suggest that several risk factors, namely, (a) the competitiveness of the education system, (b) socialization processes within families and schools, and (c) developmental changes in females during puberty, may be contributing to the difference between bullying mechanisms in primary and secondary schools. Parmi les nombreuses théories contraires portant sur l'intimidation, la thèse largement acceptée, connue sous le nom de frustration-agression postule que l'intimidation est une forme de comportement agressif provoqué par le stress externe. Les chercheurs ont récemment découvert que le rapport entre les agents de stress externes et l'intimidation est parfois modéré par la frustration interne. La présente étude vise à déterminer lesquels de ces mécanismes expliquent le mieux les comportements d'intimidation par les élèves. L'analyse de données, suivant la modélisation par équation structurelle, était basée sur 1 069 filles sélectionnées de 14 écoles primaires et 16 écoles secondaires à Shenzhen, en Chine. Les résultats de l'analyse donnent à penser que l'intimidation par les filles à l'école primaire est directement liée au stress externe, alors que l'intimidation à l'école secondaire est modérée par la frustration interne. Les auteurs proposent qu'il est possible que plusieurs facteurs de risque, notamment (a) la compétitivité du système d'éducation, (b) les processus de socialisation en sein des familles et des écoles et (c) les changements de croissance chez les filles pendant la puberté, contribuent aux différences entre les mécanismes d'intimidation à l'école primaire et à l'école secondaire.

description: A 60 GHz wireless Gigabit Ethernet (G.E.) communication system capable of near gigabit data rate has been developed at IETR. The realized system covers 2 GHz available bandwidth. This paper describes the design and realization of the overall system including the baseband (BB), intermediate frequency (IF) and radiofrequency (RF) blocks. A differential binary shift keying (DBPSK) modulation and a differential demodulation are adopted at IF. In the BB processing block, an original byte/frame synchronization technique is designed to provide a small value of the preamble false alarm and missing probabilities. For the system performances, two different real scenarios are investigated: measurements carried out in a large gym and in hallways. Bit error rate (BER) measurements have been performed in different configurations: with/without RS (255, 239) coding, with frame synchronization using 32/64 bits preambles. As shown by simulation, the 64 bits preamble provides sufficient robustness and improves the system performance in term of BER. At a data rate of 875 Mbps, a BER of 10-8 was measured at 30 m using high gain antennas for line of-sight (LOS) conditions.

description: Recently, Graph Convolutional Network (GCN) has been widely used in Hyperspectral Image (HSI) classification due to its satisfactory performance. However, the number of labeled pixels is very limited in HSI, and thus the available supervision information is usually insufficient, which will inevitably degrade the representation ability of most existing GCN-based methods. To enhance the feature representation ability, in this paper, a GCN model with contrastive learning is proposed to explore the supervision signals contained in both spectral information and spatial relations, which is termed Contrastive Graph Convolutional Network (ConGCN), for HSI classification. First, in order to mine sufficient supervision signals from spectral information, a semi-supervised contrastive loss function is utilized to maximize the agreement between different views of the same node or the nodes from the same land cover category. Second, to extract the precious yet implicit spatial relations in HSI, a graph generative loss function is leveraged to explore supplementary supervision signals contained in the graph topology. In addition, an adaptive graph augmentation technique is designed to flexibly incorporate the spectral-spatial priors of HSI, which helps facilitate the subsequent contrastive representation learning. The extensive experimental results on four typical benchmark datasets firmly demonstrate the effectiveness of the proposed ConGCN in both qualitative and quantitative aspects.
Positioning Ontario’s Character Development Initiative In/Through Its Policy Web of Relationships

description: Constructing a policy web of relationships is proposed as a useful way to identify and understand complex relationships between policies and their contexts. In Canada, the province of Ontario's Character Development Initiative (CDI) and its relationships to student achievement, citizenship education, and safe schools policies provide an illustrative example of the web’s utility. Mandated by the Ontario Ministry of Education, the Character Development Initiative was expected to be implemented by all publicly funded school boards during the 2007-2008 school year. This application of the policy web shows how what happens in one policy affects what happens in another and highlights relationships between policies that might be overlooked if one’s focus is limited to a single policy’s texts, practices, or influences alone. This example also shows how creating a policy web of relationships highlights issues, texts, practices, and ideas important across different policy fields and how a particular policy is positioned in relation to other policies. This knowledge may be used to support, resist, or influence policy at different levels. Mapping the relationships between policies using a web of relationships also provides historical understanding of the policies and knowledge about why policies (re)emerge at particular moments. La création d'un réseau de relations portant sur les politiques est évoquée comme façon utile d'identifier et de comprendre les rapports complexes entre les politiques et leurs contextes. Au Canada, l'initiative ontarienne nommée Initiative de développement du caractère, et ses liens avec le rendement des élèves, l'éducation à la citoyenneté et les politiques sur la sécurité à l'école, offre un exemple de l'utilité d'un tel réseau. On s'attendait à ce que l'initiative de développement du caractère, mandatée par le Ministère de l'éducation de l'Ontario, soit mise en œuvre par toutes les écoles publiques pendant l'année scolaire 2007-2008. Cette application de réseau de politiques démontre dans quelle mesure un changement dans une politique affecte l'évolution d'une autre, et fait ressortir des liens entre les politiques dont on ne tiendrait pas compte si on limitait notre attention aux textes, pratiques ou influences d'une seule politique. De plus, cet exemple illustre la façon dont un réseau de politiques fait ressortir d'une part, l'importance de questions, textes, pratiques et idées d'un domaine à l'autre et d'autre part, la position d'une politique par rapport aux autres. Ces connaissances peuvent servir à appuyer, rejeter ou influencer les politiques à divers niveaux. Un réseau de relations entre les politiques offre également un aperçu historique de celles-ci et une explication de leur émergence à des moments donnés.

On the Decidability of Non Interference over Unbounded Petri Nets

description: Non-interference, in transitive or intransitive form, is defined here over unbounded (Place/Transition) Petri nets. The definitions are adaptations of similar, well-accepted definitions introduced earlier in the framework of labelled transition systems. The interpretation of intransitive non-interference which we propose for Petri nets is as follows. A Petri net represents the composition of a controlled and a controller systems, possibly sharing places and transitions. Low transitions represent local actions of the controlled system, high transitions represent local decisions of the controller, and downgrading transitions represent synchronized actions of both components. Intransitive non-interference means the impossibility for the controlled system to follow any local strategy that would force or dodge synchronized actions depending upon the decisions taken by the controller after the last synchronized action. The fact that both language equivalence and bisimulation equivalence are undecidable for unbounded labelled Petri nets might be seen as an indication that non-interference properties based on these equivalences cannot be decided. We prove the opposite, providing results of decidability of non-interference over a representative class of infinite state systems.

description: We introduce a suite of cosmological volume simulations to study the evolution of galaxies as part of the Feedback in Realistic Environments project. FIREbox, the principal simulation of the present suite, provides a representative sample of galaxies (~1000 galaxies with Mstar > 10^8 Msun at z=0) at a resolution (~20 pc, m_b ~ 6x10^4 Msun) comparable to state-of-the-art galaxy zoom-in simulations. FIREbox captures the multiphase nature of the interstellar medium in a fully cosmological setting (L=22.1 Mpc) thanks to its exceptionally high dynamic range (~10^6) and the inclusion of multi-channel stellar feedback. Here, we focus on validating the simulation predictions by comparing to observational data. We find that simulated galaxies with Mstar < 10^{10.5-11} Msun have star formation rates, gas masses, and metallicities in broad agreement with observations. These galaxy scaling relations extend to low masses (Mstar ~ 10^7 Msun) and follow a (broken) power-law relationship. Also reproduced are the evolution of the cosmic HI density and the HI column density distribution at z~0-5. At low z, FIREbox predicts a peak in the stellar-mass--halo-mass relation, but also a higher abundance of massive galaxies and a higher cosmic star formation rate density than observed, showing that stellar feedback alone is insufficient to reproduce the properties of massive galaxies at late times. Given its high resolution and sample size, FIREbox offers a baseline prediction of galaxy formation theory in a $Λ$CDM Universe while also highlighting modeling challenges to be addressed in next-generation galaxy simulations.
