Subjects: co-creation; theory; models; paradigms; modes; traditional review; interviews; public health

description: Executive Summary Objectives: Co-creation is a promising avenue for solutions to public health issues. To date, coherent, rigorous and systematic frameworks for co-creation, including theoretical and methodological principles, are currently lacking. Health CASCADE aims to develop such a framework for co-creation in public health. This report describes the first steps towards developing theoretical principles for co-creation in Public Health including: proposing a definition and exploring a potential theoretical lens for understanding evidence-based co-creation. There are wide-ranging definitions given for the term ‘co-creation’ but in short, Health CASCADE tentatively uses the following working definition: “An evidence-based methodology for the development, implementation and evaluation of innovations through continuous, open collaboration, interactional knowledge production and shared decision-making among key stakeholders, directed at improving public health”. Methods: A (traditional) literature review and primary semi-structured interview (undertaken with researchers in the field of co-creation within public health) were the twofold methods adopted. Key Findings: Health CASCADE is seeking to provide a methodology for the combination of an evidence-based approach (“mode 1”) and co-creation (”mode 2”). Further, participatory typologies, like Arnstein’s ladder, are very simplified conceptualisations of how participation (adult and child respectively) is seen in a project / research / programme, and so caution must be exercised. It became clear that co-creation / transdisciplinary knowledge claims are not referenced to a solely objective or subjective reality. Further when exploring suitable lenses, an ontology called ‘critical realism’ emerged in the literature and the primary interviews, as a potentially suitable lens which may be worthwhile to investigate further. For instance, as the propositions of critical realism considers objective reality as well as the role of subjective interpretation in framing reality, it could provide the balance needed for allowing co-creation. The application of thematic analysis to the primary interview data revealed some important insights. For example, when incorporating paradigms within co-creation theory framework, the interviewees advocated for the best principles from multiple paradigms to be used, and thus not merely relying on one paradigm. This report was produced as a deliverable (D1.1) for December, 2021.

description: The present note reviews some aspects of the mean field limit for Vlasov type equations with Lipschitz continuous interaction kernel. We discuss in particular the connection between the approach involving the N-particle empirical measure and the formulation based on the BBGKY hierarchy. This leads to a more direct proof of the quantitative estimates on the propagation of chaos obtained on a more general class of interacting systems in [S.Mischler, C. Mouhot, B. Wennberg, arXiv:1101.4727]. Our main result is a stability estimate on the BBGKY hierarchy uniform in the number of particles, which implies a stability estimate in the sense of the Monge-Kantorovich distance with exponent 1 on the infinite mean field hierarchy. This last result amplifies Spohn's uniqueness theorem [H. Spohn, Math. Meth. Appl. Sci. 3 (1981), 445-455].

description: We analyze broadband X-ray data of NGC 6946 X-1 and probe plausible accretion scenarios in this ULX. NGC 6946 X-1 is a persistent soft source with broadband continuum spectra described by two thermal disk components. The cool accretion disk temperature $\rm T_{cool} \sim 0.2$ keV and the presence of $\sim 0.9$ keV emission/absorption broad feature suggests the evidence of optically thick wind due to super-critical accretion. The hot geometrically modified accretion disk has an inner temperature of $\rm T_{hot} \sim 2$ keV with a radial dependent profile $\rm T(r) \propto r^{-0.5}$, expected in a slim disk scenario. Further, the measurement based on a realistic inclination angle of the disk indicates that the mass of the host compact object is comparable to $\rm \sim 6-10 ~M_{\odot}$ non-rotating black hole or the system hosts a moderately magnetized neutron star with $\rm B \lesssim 2 \times 10^{11}$ G magnetic field. Overall, the detected spectral curvature, high luminosity, flux contribution from two thermal disk components, and estimated accretion rate imprint the super-Eddington accretion scenario.

description: In the Susceptible-Infectious-Recovered (SIR) model of disease spreading, the time to extinction of the epidemics happens at an intermediate value of the per-contact transmission probability. Too contagious infections burn out fast in the population. Infections that are not contagious enough die out before they spread to a large fraction of people. We characterize how the maximal extinction time in SIR simulations on networks depend on the network structure. For example we find that the average distances in isolated components, weighted by the component size, is a good predictor of the maximal time to extinction. Furthermore, the transmission probability giving the longest outbreaks is larger than, but otherwise seemingly independent of, the epidemic threshold.

From these, the temperature dependence of experimentally relevant spatial scales -- i.e., the correlation length for spin chains and the size of magnetic domains for thin films magnetized out of plane -- are deduced. Stability of chiral order inside domain walls against thermal fluctuations is also discussed.

description: Recent experimental efforts were made to explore the Bose-Einstein condensation in multi-$α$ system using the heavy-ion collisions. This Letter provides a explanation why no signatures were observed and a guidance for future experiments. More precisely, a harmonic oscillator model is developed to study the multi-$α$ source at or near zero temperature. The temperature and particle population of the multi-$α$ sources observed in the current experiments are extracted. It is found that almost no $α$ particles occupy the ground state in those multi-$α$ sources. The critical temperature for the multi-$α$-condensed states are predicted, which provides a guidance for the future experiments to probe the Bose-Einstein condensation of $α$ clusters in the heavy-ion collisions.

description: Background Although rare, placental abruption is implicated in disproportionately high rates of perinatal morbidity and mortality. Understanding geographic and temporal variations may provide insights into possible amenable factors of abruption. We examined abruption frequencies by maternal age, delivery year, and maternal birth cohorts over three decades across seven countries. Methods Women that delivered in the US (n=863,879; 1979–10), Canada (4 provinces, n=5,407,463; 1982–11), Sweden (n=3,266,742; 1978–10), Denmark (n=1,773,895; 1978–08), Norway (n=1,780,271, 1978–09), Finland (n=1,411,867; 1987–10), and Spain (n=6,151,508; 1999–12) were analyzed. Abruption diagnosis was based on ICD coding. Rates were modeled using Poisson regression within the framework of an age-period-cohort analysis, and multi-level models to examine the contribution of smoking in four countries. Results Abruption rates varied across the seven countries (3–10 per 1000), Maternal age showed a consistent J-shaped pattern with increased rates at the extremes of the age distribution. In comparison to births in 2000, births after 2000 in European countries had lower abruption rates; in the US there was an increase in rate up to 2000 and a plateau thereafter. No birth cohort effects were evident. Changes in smoking prevalence partially explained the period effect in the US (P = 0.01) and Sweden (P<0.01). Conclusions There is a strong maternal age effect on abruption. While the abruption rate has plateaued since 2000 in the US, all other countries show declining rates. These findings suggest considerable variation in abruption frequencies across countries; differences in the distribution of risk factors, especially smoking, may help guide policy to reduce abruption rates.
Membrane potential and Ca2+ concentration dependence on pressure and vasoactive agents in arterial smooth muscle: A model
Creators: name: Karlin, Arthur
Publisher: name: Columbia University
Year: 2015
Subjects: subject: Molecular biology
subject: Biochemistry

description: Arterial smooth muscle (SM) cells respond autonomously to changes in intravascular pressure, adjusting tension to maintain vessel diameter. The values of membrane potential (V_m) and sarcoplasmic Ca^2+ concentration (Ca_in) within minutes of a change in pressure are the results of two opposing pathways, both of which use Ca^2+ as a signal. This works because the two Ca^2+-signaling pathways are confined to distinct microdomains in which the Ca^2+ concentrations needed to activate key channels are transiently higher than Cain. A mathematical model of an isolated arterial SM cell is presented that incorporates the two types of microdomains. The first type consists of junctions between cisternae of the peripheral sarcoplasmic reticulum (SR), containing ryanodine receptors (RyRs), and the sarcolemma, containing voltage- and Ca^2+-activated K^+ (BK) channels. These junctional microdomains promote hyperpolarization, reduced Cain, and relaxation. The second type is postulated to form around stretch-activated nonspecific cation channels and neighboring Ca^2+-activated Cl^− channels, and promotes the opposite (depolarization, increased Ca_in, and contraction). The model includes three additional compartments: the sarcoplasm, the central SR lumen, and the peripheral SR lumen. It incorporates 37 protein components. In addition to pressure, the model accommodates inputs of α- and β-adrenergic agonists, ATP, 11,12-epoxyeicosatrienoic acid, and nitric oxide (NO). The parameters of the equations were adjusted to obtain a close fit to reported Vm and Ca_in as functions of pressure, which have been determined in cerebral arteries. The simulations were insensitive to ±10% changes in most of the parameters. The model also simulated the effects of inhibiting RyR, BK, or voltage-activated Ca^2+ channels on V_m and Ca_in. Deletion of BK β1 subunits is known to increase arterial–SM tension. In the model, deletion of β1 raised Ca_in at all pressures, and these increases were reversed by NO.
title: Associations between Cumulative Concussion and Academic Success in University Students
Creators: name: Broggi, Michael
Publisher: name: University of Massachusetts Amherst

description: Individuals with a history of multiple concussions may be at risk for relative weaknesses in executive functioning and processing speed. These weaknesses could adversely influence academic skills and academic success. This study determined if the relative weaknesses in executive functions and processing speed mediate associations between multiple concussions and academic outcomes in university students. To achieve this aim, university students with a history of three or more concussions (n = 58) were compared to two control groups (ns = 57) on measures of executive functions, processing speed, academic skills, and academic success. Results indicated no significant differences between the groups on measures of executive functioning or processing speed. The multiple concussion group endorsed significantly more psychological symptoms, had a slower reading rate, and had a lower grade point average (GPA) than controls with no history of concussion. Executive functioning and processing speed did not mediate the associations between concussion status and academic skills or academic success. Future research should investigate other potential mediators, such as psychological symptoms, that may account for differences in academic skills and performance amongst students with multiple concussions.

description: Using decadal prediction experiments from the WCRP/CMIP5 suite that were initialized every year from 1960-onward, we explore long-lead predictability of ENSO events. Both deterministic and probabilistic skill metrics are used to assess the ability of these decadal prediction systems to reproduce ENSO variability as represented by the NINO3.4 index (EN3.4). Several individual systems as well as the multi-model mean can predict ENSO events 3–4 years in advance, though not for every event during the hindcast period. This long-lead skill is beyond the previously documented predictability limits of initialized prediction systems. As part of the analysis, skill in reproducing the annual cycle of EN3.4, and the annual cycle of its interannual variability is examined. Most of the prediction systems reproduce the seasonal cycle of EN3.4, but are less able to capture the timing and magnitude of the variability. However, for the prediction systems used here, the fidelity of annual cycle characteristics does not appear to be related to the system’s ability to predict ENSO events. In addition, the performance of the multi-model ensemble mean is explored and compared to the multi-model mean based solely on the most skillful systems; the latter is found to yield better results for the deterministic metrics. Finally, an analysis of the near-surface temperature and precipitation teleconnections reveals that the ability of the systems to detect ENSO events far in advance could translate into predictive skill over land for several lead years, though with reduced amplitudes compared to observations.

description: Aims: The aim of this work is to compare the performance of three reaction network integration methods used in stellar nucleosynthesis calculations. These are the Gear's backward differentiation method, Wagoner's method (a 2nd-order Runge-Kutta method), and the Bader-Deuflehard semi-implicit multi-step method. Methods: To investigate the efficiency of each of the integration methods considered here, a test suite of temperature and density versus time profiles is used. This suite provides a range of situations ranging from constant temperature and density to the dramatically varying conditions present in white dwarf mergers, novae, and x-ray bursts. Some of these profiles are obtained separately from full hydrodynamic calculations. The integration efficiencies are investigated with respect to input parameters that constrain the desired accuracy and precision. Results: Gear's backward differentiation method is found to improve accuracy, performance, and stability in integrating nuclear reaction networks. For temperature-density profiles that vary strongly with time, it is found to outperform the Bader-Deuflehard method (although that method is very powerful for more smoothly varying profiles). Wagoner's method, while relatively fast for many scenarios, exhibits hard-to-predict inaccuracies for some choices of integration parameters owing to its lack of error estimations.

description: The purpose of this study is to examine whether manga and anime can be used as learning materials. Manga is one of the biggest entertainments in Japan and is read all over the world. Many Japanese language learners read manga for fun and use it as a learning material. Similarly, several Japanese language learners watch anime for fun and use it as a learning material. Due to the fact that Japanese language learners use manga and anime as learning materials, this study examines whether using manga and anime together provide high contribution for inferring novel words. There were 6 participants analyzed in this study. The result showed that using both materials together had positive effects on Japanese language learners’ inferencing skills if there is no huge difference for the amount of information between manga and anime. However, if there is a huge difference for the amount of information, most Japanese language learners did not get any effect. These results indicate that using manga and anime together provide high contribution.

VFTS 822 is a relatively low-luminosity (log $L$ = 4.04 $\pm$ 0.25 $L_{\odot}$) B8[e] star. In this Letter, we evaluate the evolutionary status of VFTS 822 and discuss its candidacy as a Herbig B[e] star. If the object is indeed in the pre-main sequence phase, it would present an exciting opportunity to measure mass accretion rates at low metallicity spectroscopically, to understand the effect of metallicity on accretion rates.

description: With advances in modern pharmaceutical sciences, the processes of discovery and development of new therapeutic drugs have changed dramatically, resulted in an extraordinary improvement in potential prophylactic and therapeutic interventions. Patents for biologic agents first marketed in the early 1980s are now beginning to expire, paving the way for non-proprietary agents to enter the market. However, there are fundamental differences between biologics and traditional pharmaceuticals that preclude the extrapolation of existing regulatory processes for traditional generic agents to these new biologic products. At present, many new classes of vaccines are being developed to prevent infection and to treat cancers and chronic diseases. The benefits for disease treatment and prevention will result from a better understanding of disease pathogenesis and expanded knowledge of immune mechanisms, the molecular structures of drugs, biologics, and biotechnology. This review provides both a conceptual approach and specific information about each phase of clinical development before licensure of a drug. Italso describes the design of post-marketing studies and examines how recent advances in pharmaceutical sciences increased demand for safer and more effective drugs have changed the processes, in which drugs are developed and approved.

description: In this article, we introduce the Maximum Diversity Assortment Selection Problem (MDASP), which is a generalization of the two-dimensional Knapsack Problem (2D-KP). Given a set of rectangles and a rectangular container, the goal of 2D-KP is to determine a subset of rectangles that can be placed in the container without overlapping, i.e., a feasible assortment, such that a maximum area is covered. MDASP is to determine a set of feasible assortments, each of them covering a certain minimum threshold of the container, such that the diversity among them is maximized. Thereby, diversity is defined as the minimum or average normalized Hamming distance of all assortment pairs. MDASP was the topic of the 11th AIMMS-MOPTA Competition in 2019. The methods described in this article and the resulting computational results won the contest. In the following, we give a definition of the problem, introduce a mathematical model and solution approaches, determine upper bounds on the diversity, and conclude with computational experiments conducted on test instances derived from the 2D-KP literature.

We discuss theoretical uncertainties of the formalism related to the basis truncation, parametrization of the underlying energy density functional, and ambiguities related to determination of Slater determinants in odd-odd nuclei. A generalization of the double-projected DFT model towards a no core shell-model-like configuration-mixing approach is formulated and implemented. We also discuss new opportunities in charge-symmetry- and charge-independence-breaking studies offered by the newly developed DFT formalism involving proton-neutron mixing in the particle-hole channel.

description: Rural sub-Saharan Africa suffers from a lack of transportation infrastructure, hindering rural access for populations in remote areas to social and economic opportunities available in urban areas. Scholars have studied this issue for decades, focusing on the monetary and social imbalances caused by this isolation. I will analyze a motorbike taxi service called Boda Boda, a means of transportation widely used in East Africa and the factors affecting its use. Binary probability regressions reveal counterintuitive behavior, such as a high sensitivity to distances only for accessing non-productive activities such as health infrastructure. Poisson regressions show that the likelihood of undertaking multiple trips in Boda Boda is high only in the presence of an agricultural surplus. A qualitative analysis based on four surveys shows that Boda Boda is largely used to foster social relations and confirms that it is rarely used as a method to access health or education facilities. I postulate that Boda Boda has a positive impact on the freedom and development of remote populations. The research for this paper took place in two villages in southern Uganda from December 2013 to January 2014.

description: Asymptotically locally AdS and asymptotically flat black hole solutions are found for a particular case of the Horndeski action. The action contains the Einstein-Hilbert term with a cosmological constant, a real scalar field with a non minimal kinetic coupling given by the Einstein tensor, the minimal kinetic coupling and the Maxwell term. There is no scalar potential. The solution has two integration constants related with the mass and the electric charge. The solution is given for all dimensions. A new class of asymptotically locally flat spherically symmetric black holes is found when the minimal kinetic coupling vanishes and the cosmological constant is present. In this case we get a solution which represents an electric Universe. The electric field at infinity is only supported by $Λ$. When the cosmological constant vanishes the black hole is asymptotically flat.

They reshape and command a limited enclave of the city with their focal point being the downtown and animate their lives in these spaces to ensure they are a reflection of the imaginaire. The Biartis are a lower-income group that lives Beirut in a diverse spatial sense. They reproduce and perform a spatial life that is detached from the image, from the branding and from the globalist order. Their lived experience of BeIrut becomes a form of counter-hegemonic bloc against the Urbanista imaginaire.

description: Large scale primordial magnetic fields (PMFs) threading the intergalactic medium are observed ubiquitously in the Universe playing a key role in the cosmic evolution. Their origin is still debated constituting a very active field of research. In the present article, we propose a novel natural ab initio mechanism for the origin of such PMFs through the portal of supermassive primordial black holes (PBHs) forming between the Big Bang Nucleosynthesis and the recombination era. In particular, by considering PBHs furnished with a locally isothermal disk we study the generation of a Biermann battery induced seed magnetic field (MF) due to the vortexlike motion of the primordial plasma around the black hole. Finally, by considering monochromatic PBH mass distributions and deriving the relevant MF power spectrum we make a conservative estimate for the seed PMF in intergalactic scales and at redshift $z=30$, when typical galaxies are considered to form, which reads as $B\simeq 10^{-30}\mathrm{G}\left(\frac{\ell_\mathrm{R}}{10^6}\right)^2\left(\frac{M_\mathrm{PBH}}{10^{14}M_\odot}\right)^{5/2}$, where $M_\mathrm{PBH}$ is the PBH mass and $\ell_\mathrm{R}\equiv R_\mathrm{d}/R_\mathrm{ISCO}$, is the ratio of the radius of the disk, $R_\mathrm{d}$ over the radius of the innermost stable circular orbit, $R_\mathrm{ISCO}$. Interestingly enough, by requiring to seed a PMF of the order of $10^{-30}\mathrm{G}$ necessary to give rise to a present day $10^{-18}\mathrm{G}$ in intergalactic scales, we find a lower bound on the PBH mass within the range $[10^{10}- 10^{16}]M_\odot$ depending on the radius of the PBH disk.

description: The dissertation attempts to provide a structured account of the factional competition among German diplomats between 1898 and 1909. It will analyse how these rivalries impacted on Anglo-German relations during the period. The hypothesis of this work proposes that the centre of gravity in German foreign policy making shifted between 1898 and 1909 from the civilian opponents of the Emperor’s interference in foreign affairs to the supporters of ‘personal rule’, and that this shift then allowed the navy to become the most influential agency in foreign policy making. While the faction which resisted the Kaiser’s meddling was strong when Bernhard von Bülow entered government in October 1897, its influence declined as the Foreign Secretary, who became Chancellor in 1900, consolidated his power and acted as the foremost champion of the Emperor’s ‘personal rule’ in foreign affairs. By tying his political career to being the executive tool of the Kaiser’s will, Bülow eventually paved the way for the navy to become the dominant factor of influence in Anglo-German relations. The civilian policy makers had thus lost their ability to determine the course of Germany’s foreign affairs without constant consideration for the military branch most favoured by the emperor. Effectiveness of Germany’s British policy was also conditioned by the strategic reassessment that British foreign policy underwent during the period under consideration

description: This paper asks a simple question: do microcredit programs positively affect the standard of living of poor households with little or no land ownership? Access to credit at favorable terms is likely to increase the number of economic opportunities available to a rural household. I use a fixed effect regression model to explore panel data on 855 households from Bangladesh compiled from an extensive household survey conducted between 1991 and 1999. I explored seven representative measures for different aspects of standard of living: household per capita weekly non-food expenditure, household per capita weekly food expenditure, household non-land asset ownership, household female non-land asset ownership, household landholding, highest number of years of education of any household female, and highest number of years of education of any household male. The results suggest that microcredit program participation had positive impact on per capita food expenditure, landholding, and women’s ownership of non-land assets. Microcredit seems to have had no significant, positive impact on overall household non-land asset accumulation and educational attainment.

description: Historically, student activism played a prominent role in Burmese democratic movements, yet today its role has diminished. This thesis investigates the rise and decline of Burmese student activism along three levels of analysis -- international, state, and civil society -- using over sixty first-hand interviews conducted by the author with student leaders from the past fifty years. It analyzes Burmese student movements through the “dynamics of contention” approach to social movements. Most prominently, the theory of political opportunity structures (POS) is applied to the state-level analysis. The analytical framework follows a chronological order of three phases: 1962 to 1988; 1988 to 2000s; and 2000s to today.

description: Alpha emissivity measurements are important in the semiconductor industry for assessing the suitability of materials for use in production processes. A recently published round-robin study that circulated the same samples to several alpha counting centers showed wide center-to-center variations in measured alpha emissivity. A separate analysis of these results hypothesized that much of the variation might arise from differences in sample-to-entrance window separations. XIA recently introduced an ultra low background counter, the UltraLo-1800 (UltraLo), that operates in a fundamentally different manner from the proportional counters used at most of the centers in the original study. In particular, by placing the sample within the counting volume, it eliminates the sample-to-entrance window separation issue noted above, and so offers an opportunity to test this hypothesis. In this work we briefly review how the UltraLo operates and describe a new round-robin study conducted entirely on UltraLo instruments using a set of standard samples that included two samples used in the original study. This study shows that, for LA (Low Alpha between 2 and 50 alpha/khr-cm$^2$) sample measurements, the only remaining site-to-site variations were due to counting statistics. Variations in ULA (Ultra-Low Alpha < 2 alpha/khr-cm$^2$) sample measurements were reduced three-fold, compared to the earlier study, with the measurements suggesting that residual activity variations now primarily arise from site-to-site differences in the cosmogenic background.

title: An Experimental Investigation of How Peer Criticism and Praise Affect Urges for Self-Injury
Creators: name: Haliczer, Lauren
Publisher: name: University of Massachusetts Amherst

description: Nonsuicidal self-injury (NSSI) is prevalent among young adults, and is associated with increased suicide risk. The self-punishment hypothesis theorizes that individuals who are highly self-critical may engage in NSSI due to finding the experience of pain as ego-syntonic. Although evidence links self-critical views to NSSI, minimal research has examined how these views are influenced by more proximal social stressors, such as peer criticism, to trigger NSSI urges. The current study addresses the following questions: (1) Will the effects of recalled peer criticism (vs. praise and a neutral interaction) on pain endurance (a proxy measure for NSSI urges) and self-reported NSSI urges be moderated by group status (i.e., whether or not an individual has a history of NSSI)? We hypothesized that group status would moderate the effects of recalled peer criticism on pain endurance and NSSI urges, such that the relationships between these constructs would be stronger among the NSSI group vs. the no NSSI group; (2) If these interaction effects are present, will they be mediated by self-critical views? We hypothesized that the interaction between group status and peer criticism on pain endurance and NSSI urges would decrease in magnitude after accounting for self-critical views. Participants were 137 young adult women with either a recent or recurrent history of NSSI (n = 79) or no NSSI history (n = 58). Idiographic scripts of a recalled peer interaction involving critical, praising, or neutral feedback were used as the experimental manipulation, and measures of pain endurance (via a pressure algometer) and self-reported NSSI urges were administered at baseline and post-manipulation. The NSSI group demonstrated marginally higher pain endurance and stronger self-critical views than the control group. The overall effects of recalled peer criticism were not moderated by group status in predicting pain endurance or NSSI urges. Exploratory pairwise comparisons revealed that those in the NSSI group who received criticism (vs. the other conditions) demonstrated a significant increase in NSSI urges. Findings highlight peer criticism as one context in which risk for NSSI urges may be elevated among those with a history of NSSI, and underscore self-critical views as an important intervention target.

description: These Sessional Clippings books cover the period 1891 to 1972, and include newspaper accounts written by various legislative reporters who covered debates occurring in the British Columbia Legislative Assembly. Transcripts of debates of the Legislative Assembly (Hansard) were not published in B.C. until 1970; hence these "Sessional Clipping Books" augment the "Journals", the record of daily proceedings of the Legislative Assembly. Selected clippings from various newspapers including the Vancouver Sun, the Vancouver Province, the Colonist, and the Times newspapers, relating to the newspaper reports concerning activities of the Legislature. The original sessional clippings books comprise 351 ledger size print volumes, held at the Legislative Library in Victoria BC. The print volumes were microfilmed onto 26 reels in 1977 under a Tri University Libraries (TRIUL) project by Precision Micrographic Services (Vancouver, B.C.), with the permission of the Legislative Library, Victoria, British Columbia. This digital collection was created by scanning the 26 microfilm reels.
