description: 3D object detection is vital for many robotics applications. For tasks where a 2D perspective range image exists, we propose to learn a 3D representation directly from this range image view. To this end, we designed a 2D convolutional network architecture that carries the 3D spherical coordinates of each pixel throughout the network. Its layers can consume any arbitrary convolution kernel in place of the default inner product kernel and exploit the underlying local geometry around each pixel. We outline four such kernels: a dense kernel according to the bag-of-words paradigm, and three graph kernels inspired by recent graph neural network advances: the Transformer, the PointNet, and the Edge Convolution. We also explore cross-modality fusion with the camera image, facilitated by operating in the perspective range image view. Our method performs competitively on the Waymo Open Dataset and improves the state-of-the-art AP for pedestrian detection from 69.7% to 75.5%. It is also efficient in that our smallest model, which still outperforms the popular PointPillars in quality, requires 180 times fewer FLOPS and model parameters

description: We propose the projected BCS wave function as the ground state for the doped Mott insulator SrCu2(BO3)2 on the Shastry-Sutherland lattice. At half filling this wave function yields the exact ground state. Adding mobile charge carriers, we find a strong asymmetry between electron and hole doping. Upon electron doping an unusual metal with strong valence bond correlations forms. Hole doped systems are d-wave RVB superconductors in which superconductivity is strongly enhanced by the emergence of inhomogeneous plaquette bond order.

description: It is shown that the Weyl fractional derivative can quantize an open system. A fractional kicked rotor is studied in the framework of the fractional Schrodinger equation. The system is described by the non-Hermitian Hamiltonian by virtue of the Weyl fractional derivative. Violation of space symmetry leads to acceleration of the orbital momentum. Quantum localization saturates this acceleration, such that the average value of the orbital momentum can be a direct current and the system behaves like a ratchet. The classical counterpart is a nonlinear kicked rotor with absorbing boundary conditions.

description: The subject of this study is the political socialization of high school students through the courses "Modern World: Citizenship and Democracy" and "Sociology". First, an overview of the basic theoretical concepts that constitute the joints of work is attempted and then the social socialization as a consequence of the educational process as well as the influence of the dominant ideology in it is examined. Below, the political socialization of students and political education in Greece, Sweden, Finland and France are examined, as shown by relevant research. Finally, in the research part of the work, a content analysis was carried out in the school textbooks of the two examined subjects, in order to highlight their influence on the political socialization of the students. For its successful completion, specific chapters were selected from each textbook, which were judged to play a more important role in this direction.
Dielectronic recombination of Fe^{13+}: benchmarking the M-shell

Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: We have carried-out a series of multi-configuration Breit-Pauli AUTOSTRUCTURE calculations for the dielectronic recombination of Fe^{13+}. We present a detailed comparison of the results with the high-energy resolution measurements reported recently from the Heidelberg Test Storage Ring by Schmidt et al. Many Rydberg series contribute significantly from this initial 3s^2 3p M-shell ion, resulting in a complex recombination `spectrum'. While there is much close agreement between theory and experiment, differences of typically 50% in the summed resonance strengths over 0.1-10 eV result in the experimentally based total Maxwellian recombination rate coefficient being a factor of 1.52-1.38 larger than theory over 10^4-10^5 K, which is a typical temperature range of peak abundance for Fe^{13+} in a photoionized plasma. Nevertheless, this theoretical recombination rate coefficient is an order of magnitude larger than that used by modellers to-date. This may help explain the discrepancy between the iron M-shell ionization balance predicted by photoionization modelling codes such as ION and CLOUDY and that deduced from the iron M-shell unresolved-transition-array absorption feature observed in the X-ray spectrum of many active galactic nuclei. Similar data are required for Fe^{8+} through Fe^{12+} to remove the question mark hanging over the atomic data though.

description: We present the results of a study aimed at assessing the differences in the dis- tribution of rotation speeds, N (v sin i) among young (1-15 Myr) B stars spanning a range of masses 6 < M/M < 12 and located in different environments: 7 low density (rho < 1 M /pc^3) ensembles that are destined to become unbound stellar associations, and 8 high density (rho >> 1 M /pc^3) ensembles that will survive as rich, bound stellar clusters for ages well in excess of 10^8 years. Our results demonstrate (1) that independent of environment, the rotation rates for stars in this mass range do not change by more than 0.1 dex over ages t ~ 1 to t ~ 15 Myr; and (2) that stars formed in high density regions lack the cohort of slow rotators that dominate the low density regions and young field stars. We suggest that the differences in N(v sin i) between low and high density regions may reflect a combination of initial conditions and environmental effects: (1) the higher turbulent speeds that characterize molecular gas in high density, cluster- forming regions; and (2) the stronger UV radiation fields and high stellar densities that characterize such regions.
A Yukawa coupling parameterization for type I+ II seesaw formula and applications to lepton flavor violation and leptogenesis

description: In the type I + II seesaw formula the mass matrix of light neutrinos m_nu receives contributions from the exchanges of both heavy Majorana neutrinos and SU(2)_L-triplet Higgs bosons. We propose a new parameterization for the Dirac-type Yukawa coupling matrix of neutrinos in this case, which generalizes the well known Casas-Ibarra parameterization to type I + II seesaw and is useful when the triplet term in m_nu is known. Neutrino masses and mixing, lepton flavor violation in decays like mu -> e γwithin mSUGRA models and leptogenesis can then be studied within this framework. We illustrate the usefulness of our new parameterization using a number of simple examples.

Highly r-process enhanced stars in ultra-faint dwarf galaxies

description: Highly r-process enhanced metal-poor stars (MP r-II, $\rm [Eu/Fe]>1$ and $\rm [Fe/H]\lesssim-1.5$) have been observed in ultra-faint dwarf (UFD) galaxy, specifically in Reticulum~II (Ret~II). The fact that only a few UFDs contain such stars implies that the r-process site may reflect very rare, but individually prolific events, such as neutron star mergers (NSMs). Considering the relatively short star formation history (SFH) of UFDs, it is puzzling how they could experience such a rare phenomenon. In this work, we show the results of cosmological hydrodynamic zoom-in simulations of isolated UFDs ($M_{vir}\approx10^7-10^8$ solar mass and $M_{\ast}\approx10^3-10^4$ solar mass at $z=0$) to explain the formation of MP r-II stars in UFDs. We employ a simple toy model for NSM events, adopting parameters consistent with observations, such as the NSM rate (1 per $M_{\ast}\approx10^5$ solar mass) and europium (Eu) mass ($M_{Eu}\approx10^{-5}$ solar mass). We identify only one simulated galaxy ($ M_{vir}\approx4.6\times10^7$, $M_{\ast}\approx 3.4\times 10^3$ solar mass at $z=0$) with abundances similar to Ret~II in a simulation volume that hosts $\sim30$ UFD analogs, indicating that such abundances are possible but rare. By exploring a range of key parameters, we demonstrate that the most important factor in determining the formation of MP r-II stars in UFDs is how quickly subsequent stars can be formed out of r-process enriched gas. We find that it takes between 10 to 100~Myr to form the first and second burst of MP r-II stars. Over this period, Eu-polluted gas maintains the required high abundance ratios of $\rm [Eu/Fe]>1$.

Job satisfaction and role conflict among community health nurses
Creators: name: Tomich, Margaret Ann Urquhart
Publisher: name: University of British Columbia

description: A descriptive correlation design was used to assess the level of job satisfaction and role conflict of community health nurses in the province of British Columbia, and to examine the relationship between these two constructs and age, length of job tenure, experience in nursing, and educational background. Although other studies have reported on decreased levels of job satisfaction among American community health nurses, decreased job satisfaction among community health nurses in British Columbia has not been associated with increased personnel turnover. This relationship between job satisfaction and turnover rate was inconsistent with that found among hospital nurses and community health nurses in the United States. The role episode model (Kahn, Wolfe, Quinn, Snoek, & Rosenthal, 1964) was used as a framework for the study. The findings from the data collected through a mail-out survey using the McCloskey/Mueller Satisfaction Scale (MMSS) (Mueller & McCloskey, 1990) and the Abridged Role Questionnaire (Rizzo, House, & Lirtzman, 1970). The data from a total of 123 mail-out surveys was used in the analysis. The community health nurses were satisfied in their work role and had moderate levels of role conflict. They were most satisfied with the measures of scheduling, extrinsic rewards, and coworkers. They were least satisfied with the measures of control and responsibility, balance of family and work, and professional opportunities. Praise and recognition, and control and responsibility were found to have the greatest impact on the nurses' ability to adapt to role conflict. Balance of family and work, and professional opportunities were found to have a minimal impact. However, role conflict was reduced by an increase in satisfaction with any of the measures. The community health nurse's level of role conflict was not influenced by age, length of job tenure, educational background, or experience in nursing. However, the greater the age, the greater the satisfaction with extrinsic rewards; the lower the educational preparation, the greater the satisfaction with control and responsibility; and, the greater the length of job tenure, the greater the satisfaction with professional opportunities. The knowledge about the factors that influence job satisfaction of community health nurses reported in this study will assist community health nurses to substantiate job needs to their employers. In addition, it will benefit nurse managers in maintaining sources of job satisfaction, foster job development needs, and reduce forces that lead to role conflict.
Climate Change and the Constitution: The Case for the Ecological Limitation

description: In this article, I explore the doctrinal argument for establishing a new implication in Australian constitutional law. The ‘ecological limitation’ is a proposed constitutional implication restraining some forms of Commonwealth or state legislative and executive action worsening climate change. The argument for its derivation is based on the premise that such action poses a threat to the long-term structural integrity, if not existence, of the Australian constitutional system. When domestic government action threatens this system, even in a partial or incremental manner, the High Court may derive implications from the Commonwealth Constitution to restrain such action. This is the reasoning underpinning the Court’s establishment of implied limitations such as the Melbourne Corporation and political communication limitations. In order to help assess the doctrinal merits of the ecological limitation, I examine a hypothetical matter centring on whether Queensland government approval of a coal mine being pursued by Adani Mining Pty Ltd breaches this limitation.

description: We consider a magnetic skyrmion crystal formed at the surface of a topological insulator. Incorporating the exchange interaction between the helical Dirac surface states and the periodic Néel or Bloch skyrmion texture, we obtain the resulting electronic band structure and discuss the constraints that symmetries impose on the energies and Berry curvature. We find substantive qualitative differences between the Néel and Bloch cases, with the latter generically permitting a multiband low energy tight-binding representation whose parameters are tightly constrained by symmetries. We explicitly compute the associated Wannier orbitals, which resemble the ringlike chiral bound states of helical Dirac fermions coupled to a single skyrmion in a ferromagnetic background. We construct a two-band tight-binding model with real nearest-neighbor hoppings which captures the salient topological features of the low-energy bands. Our results are relevant to magnetic topological insulators (TIs), as well as to TI-magnetic thin film heterostructures, in which skyrmion crystals may be stabilized.

description: It is commonly believed that the observed overabundances of many chemical species relative to the expected cluster metallicity in blue horizontal branch (BHB) stars appear as a result of atomic diffusion in the photosphere. The slow rotation of BHB stars (with T_eff > 11,500K), typically v sin{i} < 10 km/s, is consistent with this idea. In this work we search for observational evidence of vertical chemical stratification in the atmosphere of HD135485. If this evidence exists, it will demonstrate the importance of atomic diffusion processes in the atmospheres of BHB stars. We undertake an extensive abundance stratification analysis of the atmosphere of HD135485, based on recently acquired high resolution and S/N CFHT ESPaDOnS spectra and a McDonald-CE spectrum. Our numerical simulations show that nitrogen and sulfur reveal signatures of vertical abundance stratification in the stellar atmosphere. It appears that the abundances of these elements increase toward the upper atmosphere. This fact cannot be explained by the influence of microturbulent velocity, because oxygen, carbon, neon, argon, titanium and chromium do not show similar behavior and their abundances remain constant throughout the atmosphere. It seems that the iron abundance may increase marginally toward the lower atmosphere. This is the first demonstration of vertical abundance stratification of metals in a BHB star.

Gauge boson families in grand unified theories of fermion masses: E_6^4 x S_4

description: In third quantization the origin of fermion families is easy to understand: the electron field, the muon field and the tau field are identical fields in precisely the same sense as three electrons are identical and undistinguishable particles of a theory of second quantization. In both cases, the permutation of these fields or particles leaves the lagrangian invariant. One can also extend the concept of family to gauge bosons. This can be obtained through the semidirect product of the gauge group with the group of permutations of n objects. In this paper we have studied the group E_6^4 x S_4. We explain why we have chosen E_6 as fundamental gauge group factor and why we start with a model with four gauge boson/fermion families to accommodate and to fit the standard model with only three fermion families. We suggest a possible symmetry breaking pattern of E_6^4 x S_4 that could explain quark, lepton and neutrino masses and mixings.

description: The aim of this essay is to briefly present the heterologous fertilization method and the requirements the greek legislation has, for this procedure. At the same time this essay presents the issue of gamete donors’ anonymity, analyzing the arguments of those who stand in favor and against it. Also legislation is examined for countries that adopted donors’ anonymity and for ones that waived donors’ anonymity. Furthermore, the use of expanded genetic screening in the heterologous fertilization method is analyzed, emphasizing to moral and legal issues that arise. Meanwhile, there is a reference to the new genetic technologies that have been developed over the last years. Finally, it is presented whether the anonymity of gamete donors’ could be threatened by the evolution in genetic technology and the use of internet or not.

description: The sensitivity of Density Functional Theory plus Dynamical Mean Field Theory calculations to different constructions of the correlated orbitals is investigated via a detailed comparison of results obtained for the quantum material NdNiO$_2$ using different Wannier and projector methods to define the correlation problem. Using the same interaction parameters we find that the different methods produce different results for the orbital and band basis mass enhancements and for the orbital occupancies, with differing implications regarding the importance of multiorbital effects and charge transfer physics. Using interaction parameters derived from cRPA enhances the difference in results. For the isostructural cuprate CaCuO$_2$, the different methods give quantitatively different mass enhancements but still result in the same qualitative physics.

description: We propose a test for model specification of a parametric diffusion process based on a kernel estimation of the transitional density of the process. The empirical likelihood is used to formulate a statistic, for each kernel smoothing bandwidth, which is effectively a Studentized $L_2$-distance between the kernel transitional density estimator and the parametric transitional density implied by the parametric process. To reduce the sensitivity of the test on smoothing bandwidth choice, the final test statistic is constructed by combining the empirical likelihood statistics over a set of smoothing bandwidths. To better capture the finite sample distribution of the test statistic and data dependence, the critical value of the test is obtained by a parametric bootstrap procedure. Properties of the test are evaluated asymptotically and numerically by simulation and by a real data example.

description: We consider the time evolution of a wave packet representing a quantum particle moving in a geometrically open billiard that consists of a number of fixed hard-disk or hard-sphere scatterers. Using the technique of multiple collision expansions we provide a first-principle analytical calculation of the time-dependent autocorrelation function for the wave packet in the high-energy diffraction regime, in which the particle's de Broglie wave length, while being small compared to the size of the scatterers, is large enough to prevent the formation of geometric shadow over distances of the order of the particle's free flight path. The hard-disk or hard-sphere scattering system must be sufficiently dilute in order for this high-energy diffraction regime to be achievable. Apart from the overall exponential decay, the autocorrelation function exhibits a generally complicated sequence of relatively strong peaks corresponding to partial revivals of the wave packet. Both the exponential decay (or escape) rate and the revival peak structure are predominantly determined by the underlying classical dynamics. A relation between the escape rate, and the Lyapunov exponents and Kolmogorov-Sinai entropy of the counterpart classical system, previously known for hard-disk billiards, is strengthened by generalization to three spatial dimensions. The results of the quantum mechanical calculation of the time-dependent autocorrelation function agree with predictions of the semiclassical periodic orbit theory.

Επίσης, φάνηκε ότι οι θεραπευόμενοι πριν ή/και μετά τις διακοπές εκδραματίζουν συχνά, ακυρώνοντας τις θεραπευτικές συνεδρίες. Επίσης, έρχονται αντιμέτωποι με ζητήματα αποχωρισμού και απώλειας καθώς και με μια ποικιλία συναισθημάτων. Τα σημεία που αναδύθηκαν από την παρούσα έρευνα δύναται να λειτουργήσουν ως αφετηρία για περαιτέρω διερεύνηση του σύνθετου ζητήματος των διακοπών στην ψυχοθεραπεία.
description: The current study, occasioned by the relevant gap in the research literature, attempted to highlight the issues that have arisen in the time phase of the planned interruptions –vacations of Christmas, Easter and summer- in psychodynamic psychotherapy and the frequency of references on this topic during the treatment sessions. Fifteen sessions of individual psychodynamic adults’ psychotherapy were selected among therapies conducted within the context of the research project "Relational Mind". Two female therapists and three patients, two women and one man, participated in these sessions. Thematic analysis was used as a method of analysis of the research material. The study’s findings indicated that there is frequent mention to the issue of vacations, mainly in the form of announcement and not so much in the form of elaboration and analysis of this phenomenon. Additionally, it has been demonstrated that patients, before and/or after vacations, tend to act out and cancel therapeutic sessions. They, also, confront with issues of separation and loss, as well as a variety of emotions. The points that emerged from this study may serve as a starting point for further research upon the complex topic of vacations in psychotherapy.

description: Spatio-temporal models are widely used in many research areas including ecology. The recent proliferation of the use of in-situ sensors in streams and rivers supports space-time water quality modelling and monitoring in near real-time. A new family of spatio-temporal models is introduced. These models incorporate spatial dependence using stream distance while temporal autocorrelation is captured using vector autoregression approaches. Several variations of these novel models are proposed using a Bayesian framework. The results show that our proposed models perform well using spatio-temporal data collected from real stream networks, particularly in terms of out-of-sample RMSPE. This is illustrated considering a case study of water temperature data in the northwestern United States.

description: We monitored 13 moderate luminosity active galactic nuclei at z=0.36 to measure flux variability, explore feasibility of reverberation mapping, and determine uncertainties on estimating black hole mass from single-epoch data. Spectra and images were obtained with approximately weekly cadence for up to 4 months, using the KAST spectrograph on the 3-m Shane Telescope. In broad band we detect peak-to-peak variations of 9-37% and rms variations of 2-10%. The observed flux variability in the g' band (rest-frame 2800-4000Å) is consistent with that in the r' band (rest-frame 4000-5200Å), but with larger amplitude. However, after correcting for stellar light dilution, using Hubble Space Telescope images, we find nuclear variability of 3-24% (rms variation) with similar amplitudes in the g' and r' bands within the errors. Intrinsic flux variability of the H$β$ line is also detected at the 3-13% level, after accounting for systematic errors on the spectrophotometry. This demonstrates that a reverberation mapping campaign beyond the local universe can be carried out with a 3-m class telescope, provided that sufficiently long light curves are obtained. Finally, we compare the H$β$ FWHM measured from mean spectra with that measured from single-epoch data, and find no bias but an rms scatter of 14%, mostly accounted for by the uncertainty on FWHM measurements. The propagated uncertainty on black hole mass estimates, due to the FWHM measurement errors using low S/N (10--15 per pixel) single-epoch spectra, is 30%.

description: Η έρευνα πάνω σε εκπαιδευτικά και παιδαγωγικά θέματα έχει αναγνωρίσει την Επαυξημένη Πραγματικότητα ως μια τεχνολογία, η οποία μπορεί να συμβάλλει σημαντικά σε καλύτερα μαθησιακά αποτελέσματα. Ωστόσο στη βιβλιογραφία παρουσιάζονται ελλείψεις για τον βαθμό στον οποίο η συγκεκριμένη τεχνολογία μπορεί να υποστηρίξει τη διδασκαλία του κύκλου του νερού, σε μαθητές πρωτοβάθμιας εκπαίδευσης. Η παρούσα μελέτη διερευνά τα μαθησιακά αποτελέσματα της εφαρμογής επαυξημένης πραγματικότητας για φορητές συσκευές «Το ταξίδι του νερού», που σχεδιάστηκε και αναπτύχθηκε για τις ανάγκες της συγκεκριμένης έρευνας. Η μελέτη πραγματοποιήθηκε σε μαθητές της Β’ Δημοτικού. Τα αποτελέσματα της έρευνας, όπως αυτά προέκυψαν από τη συμπλήρωση αντίστοιχου φύλλου εργασίας από τους μαθητές, δεν έδειξαν στατιστικά σημαντική διαφορά στις βαθμολογίες των δύο ομάδων, με την πειραματική ομάδα ωστόσο να ανταποκρίνεται καλύτερα στο φύλλο εργασίας. Τα αποτελέσματα οδηγούν στην ανάγκη περαιτέρω διερεύνησης του θέματος για την αποτελεσματικότερη ένταξη των τεχνολογιών επαυξημένης πραγματικότητας στην εκπαιδευτική διαδικασία.
description: Research on educational and pedagogical issues has recognized Augmented Reality as a technology with great impact on cognitive learning outcomes. However, the literature lacks the degree to which this technology can support the teaching of the water cycle to primary school students. The present study investigates the learning outcomes of the Augmented Reality application for mobile devices "The Journey of Water", designed and developed for the needs of this research. The study was conducted in a group of students of the second grade of primary school. The results of the research, as they emerged from the completion of a worksheet by the students, did not show a statistically significant difference in the scores of the two groups, with the experimental group, however, responding better to the worksheet. The results lead to the need for further investigation of the issue for more effective integration of Augmented Reality technologies in the educational process.

description: Slow light in topological valley photonic crystal structures offers new possibilities to enhance light-matter interaction. We report a topological cavity based on slow light topological edge mode for broadband Purcell enhancement. The topological edge modes with large group indices over 100 can be realized with a bearded interface between two topologically distinct valley photonic crystals, featuring the greatly enhanced Purcell factor because of the increased local density of states. In the slow light regime, the topological cavity supports much more cavity modes with higher quality factor than that in the fast light regime, which is both demonstrated theoretically and experimentally. We demonstrate the cavity enables the broadband Purcell enhancement together with substantial Purcell factor, benefiting from dense cavity modes with high quality factor in a wide spectral range. It has great benefit to the realization of high-efficiency quantum-dot-based single-photon sources and entangled-photon sources with less restriction on spectral match. Such topological cavity could serve as a significant building block toward the development of photonic integrated circuits with embedded quantum emitters.

description: Graphene is a two-dimensional carbon material with a honeycomb lattice and Dirac-type low-energy spectrum. In a strong magnetic field, where Coulomb interactions dominate against disorder broadening, quantum Hall ferromagnetic states realize at integer fillings. Extending the quantum Hall ferromagnetism to the fractional filling case of massless Dirac fermions, we study the elementally charge excitations which couple with the valley degrees of freedom (so-called valley skyrmions). With the use of the density matrix renomalization group (DMRG) method, the excitation gaps are calculated and extrapolated to the thermodynamic limit. These results exhibit numerical evidences and criterions of the skyrmion excitations in graphene.

description: Recently, in arXiv, we have proposed a discussion about the Egyptian kings Shepseskaf and Userkaf, in relation to an eclipse of 2471 BC, a total eclipse that was visible from the Delta of the Nile. Here we must focus on some further points, specifically on two, which we have not previously discussed in arXiv:2412.20407, but that we can find reported by Italian newspapers and websites, particularly Wired Italia. One of these two points is regarding the end of the dominance of the solar cult, as declared by archaeoastronomer G. Magli, in newspapers and websites. This end would have been caused by the above-mentioned solar eclipse, which Shepseskaf would have witnessed and reacted accordingly. We will stress that the solar cult did not end with the end of the Fourth Dynasty; it became dominant during the following Fifth Dynasty. The kings of this V Dynasty, besides pyramids, built solar temples too. Regarding the news, we must also consider what is reported by earth.com, where we find it said that "evidence of this eclipse exists ... in... ancient texts". No ancient Egyptian text refers to the eclipse of 2471 BC. The other point we discuss is the interior of Shepseskaf’s mastaba. We will see that the orientations of the entrance of the Mastabat Fara’un and of its burial chamber are the same as in the case of the Giza pyramids. Therefore, in the last part of our work, we prefer to add also a discussion about the orientation of entrances, burial chambers and sarcophagi of the pyramids of the Fourth Dynasty, including Seila, Meidum, Bent, Red and Giza pyramids. It is strictly necessary to note that the Mastabat Fara’un was restored by Khaemwaset, the fourth son of Ramesses II. We know this fact from an inscription on the monument. In this inscription, we can find that the Shepseskaf’s burial place was defined as a pyramid.
Municipal policy and program options for affordable home ownership: a City of Toronto case study
Creators: name: Urquhart, Heather J.
Publisher: name: University of British Columbia

description: As the level of government closest to people, municipalities are left face-to-face with the failures of the housing market and the lack or failure of senior-level government housing programs. The federal government has practically withdrawn from social housing since the mid-1980s, and most of its home ownership programs do not address home ownership affordability. The Ontario government is the only provincial government to step into the gap, and it is now under increasingly serious financial pressure. Municipalities, therefore, are often looking for ways in which they can help ameliorate their local housing problems, though they have a much more limited tax base upon which to draw. The question this paper attempts to answer is, "What kinds of home ownership assistance programs could municipalities undertake to meet their housing policy objectives?" The question in these tight fiscal times also encompasses, "How can municipalities undertake such a program at minimum cost?" This paper reviews, categorizes, and assesses a variety of home ownership assistance program mechanisms from Canada, Britain, the United States, and Australia. It identifies a set of options and means to implement them that are most likely to effectively meet the needs of municipalities. It presents, through the City of Toronto case study, a process by which municipalities can characterize their housing market for their low-to-moderate income citizens. The "affordability gap" -- the gap between housing prices affordable to those households and local costs to produce adequate housing for them -- is one useful measure of the depth of the problem, of the potential cost of addressing it, and a rule against which to measure the effectiveness of various possible assistance measures. One implication of this paper is that a quite detailed analysis of the local housing market demand and supply is needed to identify the most effective and lowest-cost home ownership assistance measures.
