description: Biological information processing as implemented by regulatory and signaling networks in living cells requires sufficient specificity of molecular interaction to distinguish signals from one another, but much of regulation and signaling involves somewhat fuzzy and promiscuous recognition of molecular sequences and structures, which can leave systems vulnerable to crosstalk. This paper examines a simple computational model of protein-protein interactions which reveals both a sharp onset of crosstalk and a fragmentation of the neutral network of viable solutions as more proteins compete for regions of sequence space, revealing intrinsic limits to reliable signaling in the face of promiscuity. These results suggest connections to both phase transitions in constraint satisfaction problems and coding theory bounds on the size of communication codes.

description: The problem of nonlocality in the dynamical three-body Casimir-Polder interaction between an initially excited and two ground-state atoms is considered. It is shown that the nonlocal spatial correlations of the field emitted by the excited atom during the initial part of its spontaneous decay may become manifest in the three-body interaction. The observability of this new phenomenon is discussed.

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We use the symmetries of monolayer graphene to write a set of constraints that must be satisfied by any electron-phonon interaction hamiltonian. The explicit solution as a series expansion in the momenta gives the most general, model-independent couplings between electrons and long wavelength acoustic and optical phonons. As an application, the possibility of describing elastic strains in terms of effective electromagnetic fields is considered in detail, with an emphasis on group theory conditions and the role of time reversal symmetry.

The rooted staggered determinant in the Schwinger model

Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: We investigate the continuum limit of the rooted staggered action in the 2-dimensional Schwinger model. We match both the unrooted and rooted staggered determinants with an overlap fermion determinant of two (one) flavors and a local pure gauge effective action by fitting the coefficients of the effective action and the mass of the overlap operator. The residue of this fit measures the difference of the staggered and overlap fermion actions. We show that this residue scales at least as O(a^2), implying that any difference, be it local or non-local, between the staggered and overlap actions becomes irrelevant in the continuum limit. For the model under consideration here, this observation justifies the rooting procedure for the staggered sea quark action.

description: Herein, we report a comparison of aluminum graphite dual‐ion cells (AGDICs) electrochemical characteristics employing the conventional 1‐ethyl‐3‐methylimidazolium chloride:aluminum trichloride (EMIMCl : AlCl3) electrolyte and two popular deep eutectic solvents (DESs), namely urea : AlCl3 and acetamide:AlCl3. The three electrolytes′ characteristics have been evaluated in terms of Al‐stripping deposition capability and cycling behavior in AGDICs. The results evidence the EMIMCl : AlCl3′s Al‐stripping deposition and rate capability in AGDICs superior characteristics addressed to the lower viscosity and higher conductivity with respect to the urea : AlCl3 and acetamide:AlCl3. On the other hand, the urea : AlCl3 guarantees a much higher columbic efficiency in AGDICs, thanks to the superior electrochemical window stability.

description: Visible light‐driven photocatalytic reduction of protons to H2 is considered a promising way of solar‐to‐chemical energy conversion. Effective transfer of the photogenerated electrons and holes to the surface of the photocatalyst by minimizing their recombination is essential for achieving a high photocatalytic activity. In general, a sacrificial electron donor is used as a hole scavenger to remove photogenerated holes from the valence band for the continuation of the photocatalytic hydrogen (H2) evolution process. Here, for the first time, the hole‐transfer dynamics from Pt‐loaded sol−gel‐prepared graphitic carbon nitride (Pt‐sg‐CN) photocatalyst were investigated using different adsorbed hole acceptors along with a sacrificial agent (ascorbic acid). A significant increment (4.84 times) in H2 production was achieved by employing phenothiazine (PTZ) as the hole acceptor with continuous H2 production for 3 days. A detailed charge‐transfer dynamic of the photocatalytic process in the presence of the hole acceptors was examined by time‐resolved photoluminescence and in situ electron paramagnetic resonance studies.

description: A nonenzymatic dynamic kinetic resolution of acyclic and cyclic benzylic alcohols is reported. The approach merges rapid transition‐metal‐catalyzed alcohol racemization and enantioselective Cu‐H‐catalyzed dehydrogenative Si‐O coupling of alcohols and hydrosilanes. The catalytic processes are orthogonal, and the racemization catalyst does not promote any background reactions such as the racemization of the silyl ether and its unselective formation. Often‐used ruthenium half‐sandwich complexes are not suitable but a bifunctional ruthenium pincer complex perfectly fulfills this purpose. By this, enantioselective silylation of racemic alcohol mixtures is achieved in high yields and with good levels of enantioselection.

description: We formalize the univariate fragment of Ben-Or, Kozen, and Reif's (BKR) decision procedure for first-order real arithmetic in Isabelle/HOL. BKR's algorithm has good potential for parallelism and was designed to be used in practice. Its key insight is a clever recursive procedure that computes the set of all consistent sign assignments for an input set of univariate polynomials while carefully managing intermediate steps to avoid exponential blowup from naively enumerating all possible sign assignments (this insight is fundamental for both the univariate case and the general case). Our proof combines ideas from BKR and a follow-up work by Renegar that are well-suited for formalization. The resulting proof outline allows us to build substantially on Isabelle/HOL's libraries for algebra, analysis, and matrices. Our main extensions to existing libraries are also detailed.

description: We report the discovery of active star formation in Digel's Cloud 2, which is one of the most distant giant molecular clouds known in the extreme outer Galaxy (EOG). At the probable Galactic radius of ~20 kpc, Cloud 2 has a quite different environment from that in the solar neighborhood, including lower metallicity, much lower gas density, and small or no perturbation from spiral arms. With new wide-field near-infrared (NIR) imaging that covers the entire Cloud 2, we discovered two young embedded star clusters located in the two dense cores of the cloud. Using our NIR and 12CO data as well as HI, radio continuum, and IRAS data in the archives, we discuss the detailed star formation processes in this unique environment. We show clear evidences of a sequential star formation triggered by the nearby huge supernova remnant, GSH 138-01-94. The two embedded clusters show a distinct morphology difference: the one in the northern molecular cloud core is a loose association with isolated-mode star formation, while the other in the southern molecular cloud core is a dense cluster with cluster-mode star formation. We propose that high compression by the combination of the SNR shell and an adjacent shell caused the dense cluster formation in the southern core. Along with the low metallicity range of the EOG, we suggest that EOG could be an excellent laboratory for the study of star formation processes, such as those triggered by supernovae, that occured during an early epoch of the Galaxy's formation. In particular, the study of the EOG may shed light on the origin and role of the thick disk, whose metallicity range matches with that of the EOG well.

The meter of Guthlac B: a generative model
Creators: name: Mines, Rachel
Publisher: name: University of British Columbia
Year: 2009

description: The approach to Old English (OE) poetic meter traditionally taken is to describe the meter in terms of a list of foot or verse (half-line) types. It has been suggested that this approach, however, is open to criticism on several points First, a list of metrical types is unconstrained in that there is no principled reason why other members may not be added to the list. Second, such a theory includes no constraints on substitutions; any metrical type may always be substituted for any other. A description in the form of a list therefore cannot rule out unmetrical lines (Halle and Keyser “Iambic Pentameter”). This thesis proposes a model of OE poetic meter based on Hanson and Kiparsky’s parametric theory of universal meter. Hanson and Kiparsky argue that the constituents relevant to meter are not arbitrary or conventional, such as a list of foot or verse types, but are just those that are also relevant to language. They propose that all poetic meters are comprised of binary feet, which, like the phonological constituents defining prominence in language, consist of a strong (S) member which is the head, or prominent position, and a weak (W) member which is an unprominent position. Structure parameters establish headedness (either SW or WS) and the number of feet in a line, A position parameter defines the maximal amount of prosodic material that may occupy a given metrical position in terms of phonological constituency: mora (μ), syllable (ϭ), foot (∅), or word (λ). Prominence rules define first, whether S positions must contain prominent constituents and/or whether W positions must contain unprominent constituents; and second, whether prominence is defined by weight, strength, or stress (“Best of all Possible Verse”). The model I have proposed for OE defines the meter in terms of a fixed number of binary left-headed (SW) feet together with constraints on both S and W positions: S positions must contain stressed syllables, further defined as the heads of prosodic words; and W may contain the heads of prosodic words only if they are prosodically weak. No metrical position may contain more than a minimal word (λmin).

description: Low-energy spin and charge excitations of one-dimensional interacting fermions are completely decoupled and propagate with different velocities. These modes however can decay due to several possible mechanisms. In this paper we expose a new facet of spin-charge separation: not only the speeds but also the damping rates of spin and charge excitations are different. While the propagation of long-wavelength charge excitations is essentially ballistic, spin propagation is intrinsically damped and diffusive. We suggest that cold Fermi gases trapped inside a tight atomic waveguide offer the opportunity to measure the spin-drag relaxation rate that controls the broadening of a spin packet.

description: Coupled map lattices (CMLs) are prototypical dynamical systems on networks/graphs. They exhibit complex patterns generated via the interplay of diffusive/Laplacian coupling and nonlinear reactions modelled by a single iterated map at each node; the maps are often taken as unimodal, e.g., logistic or tent maps. In this letter, we propose a class of higher-order coupled dynamical systems involving the hypergraph Laplacian, which we call coupled hypergraph maps (CHMs). By combining linearized (in-)stability analysis of synchronized states, hypergraph spectral theory, and numerical methods, we detect robust regions of chaotic cluster synchronization occurring in parameter space upon varying coupling strength and the main bifurcation parameter of the unimodal map. Furthermore, we find key differences between Laplacian and hypergraph Laplacian coupling and detect various other classes of periodic and quasi-periodic patterns. The results show the high complexity of coupled graph maps and indicate that they might be an excellent universal model class to understand the similarities and differences between dynamics on classical graphs and dynamics on hypergraphs.

description: We study the effect of a relevant double-trace deformation on the partition function (and conformal anomaly) of a CFT at large N and its dual picture in AdS. Three complementary previous results are brought into full agreement with each other: bulk and boundary computations, as well as their formal identity. We show the exact equality between the dimensionally regularized partition functions or, equivalently, fluctuational determinants involved. A series of results then follows: (i) equality between the renormalized partition functions for all d; (ii) for all even d, correction to the conformal anomaly; (iii) for even d, the mapping entails a mixing of UV and IR effects on the same side (bulk) of the duality, with no precedent in the leading order computations; and finally, (iv) a subtle relation between overall coefficients, volume renormalization and IR-UV connection. All in all, we get a clean test of the AdS/CFT correspondence beyond the classical SUGRA approximation in the bulk and at subleading O(1) order in the large-N expansion on the boundary.

description: Purpose: A proposed mechanism for the enhanced effectiveness of hyperthermia and doxorubicin (Dox) combinations is increased intracellular Dox concentrations resulting from heat-induced cell stress. The purpose of this study was to determine whether specific varied Dox and heat combinations produce measurable effects greater than the additive combination, and whether these effects can be attributed to heat-induced increases in intracellular Dox concentrations. Methods: HCT116, HT29 and CT26 cells were exposed to Dox and water bath heating independently. A clonogenic survival assay was used to determine cell killing and intracellular Dox concentrations were measured in HCT116 cells with mass spectrometry. Cells were exposed to heating at 42 °C (60 min) and 0.5 µg/ml of Dox at varying intervals. Synergy was determined by curve-fitting and isobologram analysis. Results: All cell lines displayed synergistic effects of combined heating and Dox. A maximum synergistic effect was achieved with simultaneous cell exposure to Dox and heat. For exposures at 42 °C, the synergistic effect was most pronounced at Dox concentrations <0.5 µg/ml. Increased intracellular concentrations of Dox in HCT116 cells caused by heat-stress did not generate a concomitant thermal enhancement. Conclusions: Simultaneous exposure of HCT116 cells to heating and Dox is more effective than sequential exposure. Heat-induced cell responses are accompanied by increased intracellular Dox concentrations; however, clonogenic survival data do not support this as the cause for synergistic cytotoxicity.

description: Machine learning models are often implemented in cohort with humans in the pipeline, with the model having an option to defer to a domain expert in cases where it has low confidence in its inference. Our goal is to design mechanisms for ensuring accuracy and fairness in such prediction systems that combine machine learning model inferences and domain expert predictions. Prior work on "deferral systems" in classification settings has focused on the setting of a pipeline with a single expert and aimed to accommodate the inaccuracies and biases of this expert to simultaneously learn an inference model and a deferral system. Our work extends this framework to settings where multiple experts are available, with each expert having their own domain of expertise and biases. We propose a framework that simultaneously learns a classifier and a deferral system, with the deferral system choosing to defer to one or more human experts in cases of input where the classifier has low confidence. We test our framework on a synthetic dataset and a content moderation dataset with biased synthetic experts, and show that it significantly improves the accuracy and fairness of the final predictions, compared to the baselines. We also collect crowdsourced labels for the content moderation task to construct a real-world dataset for the evaluation of hybrid machine-human frameworks and show that our proposed learning framework outperforms baselines on this real-world dataset as well.

description: We study the role of gravitational waves (GW) in the heat death of the universe. Due to the GW emission, in a very long period, dynamical systems in the universe suffer from persistent mechanical energy dissipation, evolving to a state of universal rest and death. With N-body simulations, we adopt a simple yet representative scheme to calculate the energy loss due to the GW emission. For current dark matter systems with mass $\sim10^{12}-10^{15} M_\odot$, we estimate their GW emission timescale as $\sim10^{19}-10^{25}$ years. This timescale is significantly larger than any baryon processes in the universe, but still $\sim10^{80}$ times shorter than that of the Hawking radiation. We stress that our analysis could be invalid due to many unknowns such as the dynamical chaos, the quadrupole momentum of halos, the angular momentum loss, the dynamic friction, the central black hole accretion, the dark matter decays or annihilations, the property of dark energy and the future evolution of the universe.

description: This dissertation aims at investigating the diverse ways creative writing affects poetry writing employing a qualitative research methodology. Taking into consideration poets that have participated in creative writing courses, the dissertation investigates not only the ways and the extent to which their writing was affected but also the participants’ general views on the features of creative writing as an educational process. Through the qualitative content analysis of semi-structured interviews, I collected and analyzed data with regard to the poets’ expectations of the creative writing courses and their views on effective ways of teaching poetry, on the content of creative writing courses and the ways of their actualization, and on the possible changes that the competition of the courses may have brought in their own writing. The outcomes of the research help towards the formation of an established relationship between creative writing and poetry and -at the same time- set the ground for a fruitful discussion on planning and organizing the creative writing courses according to the needs of future students.

description: The advantage of Cellular Potts Model (CPM) is due to its ability for introducing cell-cell interaction based on the well known statistical model i.e. the Potts model. On the other hand, Lattice gas Cellular Automata (LGCA) can simulate movement of cell in a simple and correct physical way. These characters of CPM and LGCA have been combined in a reaction-diffusion frame to simulate the dynamic of avascular cancer growth on a more physical basis.The cellular automaton is evolved on a square lattice on which in the diffusion step tumor cells (C) and necrotic cells (N) propagate in two dimensions and in the reaction step every cell can proliferate, be quiescent or die due to the apoptosis and the necrosis depending on its environment. The transition probabilities in the reaction step have been calculated by the Glauber algorithm and depend on the KCC, KNC, and KNN (cancer-cancer, necrotic-cancer, and necrotic-necrotic couplings respectively). It is shown the main feature of the cancer growth depends on the choice of magnitude of couplings and the advantage of this method compared to other methods is due to the fact that it needs only three parameters KCC, KNC and KNN which are based on the well known physical ground i.e. the Potts model.

In the present thesis, an extract from the novel Le rossignol se tait à l’ aube of French writer Elsa Triolet was translated. In order to achieve an adequate translation the in the historical conditions and in the whole of the work of the writer were studied. This particular novel is of great translating interest as it is the author's last published work and seems to summarize her entire literary path. At the same time, it is also a great translational challenge as it has a demanding language, intense intertextuality and stylistic fluctuations whose translation has been a complex task. In conclusion, literary translation, despite all technological advances, remains a laborious task that involves a series of processes and decisions from the translator's point of view, which far outweigh the simple use of a dictionary

description: This paper proposes an efficient and robust algorithm to estimate target trajectories with unknown target detection profiles and clutter rates using measurements from multiple sensors. In particular, we propose to combine the multi-sensor Generalized Labeled Multi-Bernoulli (MS-GLMB) filter to estimate target trajectories and robust Cardinalized Probability Hypothesis Density (CPHD) filters to estimate the clutter rates. The target detection probability is augmented to the filtering state space for joint estimation. Experimental results show that the proposed robust filter exhibits near-optimal performance in the sense that it is comparable to the optimal MS-GLMB operating with true clutter rate and detection probability. More importantly, it outperforms other studied filters when the detection profile and clutter rate are unknown and time-variant. This is attributed to the ability of the robust filter to learn the background parameters on-the-fly.

The ASL scheme contains three parameters, the least robust of which results to be a blocking parameter for electron neutrinos and anti-neutrinos. The parameter steering the angular distribution of neutrino heating is re-calibrated compared to the earlier work. We also present a new, fast and mesh-free algorithm for calculating spectral optical depths, which, when using Smoothed Particle Hydrodynamics (SPH), makes the neutrino transport completely particle-based. We estimate a speed-up of a factor of 100 in the optical depth calculation when comparing to a grid-based approach. In the suggested calibration we recover luminosities and mean energies within 25%. A comparison of the rates of change of internal energy and electron fraction in the neutrino-driven wind suggests comparable accuracies of ASL and M1, but a higher computational efficiency of the ASL scheme. We estimate that the ratio between the CPU hours spent on the ASL neutrino scheme and those spent on the hydrodynamics is 0.8 per timestep when considering the SPH code MAGMA2 as source code for the Lagrangian hydrodynamics, to be compared with a factor of 10 from the M1 in FLASH.

description: We propose and computationally analyze a nonvolatile static random access memory (NV-SRAM) cell using magnetic tunnel junctions (MTJs) with magnetic-field-free current-induced magnetization switching (CIMS) architecture. A pair of MTJs connected to the storage nodes of a standard SRAM cell with CIMS architecture enables fully electrical store and restore operations for nonvolatile logic information. The proposed NV-SRAM is expected to be a key component of next-generation power-gating logic systems with extremely low static-power dissipation.

description: We analyze by Monte-Carlo simulations and analytically spin dynamics of two-dimensional electron gas (2DEG) interacting with short-range scatterers in nonquantizing magnetic fields. It is shown that the spin dynamics is non-Markovian with the exponential spin relaxation followed by the oscillating tail due to the electrons residing on the closed trajectories. The tail relaxes on a long time scale due to an additional smooth random potential and inelastic processes. The developed analytical theory and Monte-Carlo simulations are in the quantitative agreement with each other.

Cosmological structure formation in scalar field dark matter with repulsive self-interaction: The Incredible Shrinking Jeans Mass

description: Scalar Field Dark Matter (SFDM) comprised of ultralight ($\gtrsim 10^{-22}$ eV) bosons is an alternative to standard, collisionless Cold Dark Matter (CDM) that is CDM-like on large scales but inhibits small-scale structure formation. As a Bose-Einstein condensate, its free-field ("fuzzy") limit (FDM) suppresses structure below the de Broglie wavelength, $λ_\text{deB}$, creating virialized haloes with central cores of radius $\simλ_\text{deB}$, surrounded by CDM-like envelopes, and a halo mass function (HMF) with a sharp cut-off on small scales. With a strong enough repulsive self-interaction (SI), structure is inhibited, instead, below the Thomas-Fermi (TF) radius, $R_\text{TF}$ (the size of an SI-pressure-supported ($n=1$)-polytrope), when $R_\text{TF} > λ_\text{deB}$. Previously, we developed tools to describe SFDM dynamics on scales above $λ_\text{deB}$ and showed that SFDM-TF haloes formed by Jeans-unstable collapse from non-cosmological initial conditions have $R_\text{TF}$-sized cores, surrounded by CDM-like envelopes. Revisiting SFDM-TF in the cosmological context, we simulate halo formation by cosmological infall and collapse, and derive its transfer function from linear perturbation theory to produce cosmological initial conditions and predict statistical measures of structure formation, such as the HMF. Since FDM and SFDM-TF transfer functions both have small-scale cut-offs, we can align them to let observational constraints on FDM proxy for SFDM-TF, finding FDM with particle masses $1 \lesssim m/(10^{-22} \text{ eV}/c^2) \lesssim 30$ corresponds to SFDM-TF with $10 \gtrsim R_\text{TF}/(1 \text{ pc}) \gtrsim 1$, favoring sub-galactic (sub-kpc) core-size. The SFDM-TF HMF cuts off gradually, however, leaving more small-mass haloes: its Jeans mass shrinks so fast, scales filtered early can still recover and grow!

description: Σκοπός της παρούσας έρευνας ήταν η μελέτη και η ανάλυση του δημοσίου λόγου των κομμάτων Ποτάμι, Ciudadanos και των πειρατικών κομμάτων Σουηδίας και Ισλανδίας, την περίοδο 2013-2017. Η έννοια του νέου Κέντρου, το οποίο είναι αυτό που αναζητείται στην εργασία αυτή, προσδιορίζεται ως το ανάχωμα προς τις λαϊκιστικές και συντηρητικές δυνάμεις, και ως ένας πολιτικός χώρος που απαιτεί μια σειρά μεταρρυθμίσεων που χαρακτηρίζονται από ριζοσπαστισμό στις επιδιώξεις και μετριοπάθεια στο τρόπο επίτευξης. Έπειτα, η ανάλυση βασίζεται στους εξής άξονες: Αντιλαϊκισμός, ευρωπαϊσμός, τρίτος δρόμος, πραγματισμός και κόμματα νέας πολιτικής, κρίση αντιπροσώπευσης και ψηφιακή δημοκρατία. Πάνω στις έννοιες αυτές, βασίζεται το θεωρητικό και το πρακτικό μέρος της εργασίας. Έπειτα, σημαντικά συνθήματα και αιτήματα των κομμάτων αυτών είναι η συμμετοχικότητα, οι δικτυακές πολιτικές, οι ανοικτές έναντι των κλειστών κοινωνιών, η υπέρβαση των παραδοσιακών ιδεολογικών διαιρέσεων, η απόρριψη των συγκρουσιακών ιδεολογιών και η στήριξη σε νέες ιδέες που προκύπτουν από το παρόν και τις σύγχρονες κοινωνικές ανάγκες. Κλείνοντας, όσον αφορά τα ερευνητικά ερωτήματα που τίθενται, τα πιο σημαντικά είναι τα εξής: Αποτελούν αυτά τα κόμματα την έκφραση της υπέρβασης των παλαιών πολιτικών πρακτικών; Και τέλος, συγκροτείται ένας νέος κεντρώος χώρος, ο οποίος διακόπτει την πορεία των παραδοσιακών κομμάτων του Κέντρου;
description: The thesis of the present project was the study and the analysis of the public speech of the political parties: Potami, Ciudadanos and the political parties of Sweden and Iceland between 2013 and 2017. The new Center, that is significant term in this project, is defined as the opponent place against populist and conservative parties and a political place that demands a lot of reformations in economy and the public sphere. The analysis is based on the following axes: Opposition to populism, europeanism, third way, pragmatism and parties of new politics, representation crisis and digital democracy. The most important research questions were about: do these parties comprise the expression of the exceedance of the old political methodology? And finally, is it comprised a new centrist place that interrupts the course of the traditional centrist parties?

School-based education for the prevention of the human immunodeficiency virus and other sexually transmitted diseases in adolescents
Creators: name: Milligan, C. Dawne
Publisher: name: University of British Columbia
Year: 2009

description: This thesis seeks to answer the questions “What combination of knowledge, skills and action is necessary to facilitate protection against the human immunodeficiency virus (HIV) and other sexually transmitted diseases (STD) in adolescents?” and “How does current education for the prevention of HIV/STD in British Columbia schools compare with these requirements?” A literature review of contemporary school-based substance abuse, pregnancy and HIV/AIDS/STD prevention programs was undertaken, with specific attention paid to theories underlying the programs. Interviews based on the literature and theory review were then conducted in three school districts in British Columbia to obtain a picture of local school-based HIV/STID prevention education. Students need to understand their level of risk and methods of preventing disease and to feel motivated and capable of implementing these methods with support from their peers and families. Educators in British Columbia are engaged in a struggle to provide the needed information, skills and support within an extremely limited time framework. They lack ministerial direction, stated goals and objectives and standardized measurement and evaluation tools with regard to HIV/STD prevention, and are facing dwindling opportunities for in-service/ training. The final chapter offers a set of recommendations. These include a clear statement of acceptance of responsibility for HIV/STD education by the Ministry of Education; joint program planning and implementation by the Ministries of Education, Health and Social Services; the creation of local school-community health advisory boards (integrating health agencies, school personnel, parents, students and community leaders into school health program planning, implementation and evaluation); increased support for the implementation of “Learning for Living”, British Columbia’s comprehensive school health program; expansion of mandatory health education courses for Grades 5-12; provision of adequate training and in-service for educators; increased attention to the needs of out-of-the mainstream youth; implementation of curricula, standards/goals/objectives and measurement/evaluation tools for HIV/STD education; provision of condoms to students free of charge; and continued and increased attention to social problems such as poverty, substance abuse and the perceived lack of life opportunities that predispose youth to problem behaviour.
