CAIS Program Structure and Performance: Evidence from Ontario
No full textThe Canadian Agricultural Income Stabilization (CAIS) program was approved in late 2003. It now serves as Canada’s sole farm safety net program, having replaced the Net Income Stabilization Account (NISA), Canadian Farm Income Program (CFIP), and provincial companion programs. However, the mechanisms of operation and actual performance of CAIS in providing stability to farm incomes are relatively unknown. In particular, to develop expectations of future farm costs and returns and to determine their support for CAIS as the sole safety net under the federal-provincial Agricultural Policy Framework (APF), farmers and their representatives need a concrete understanding of how CAIS can be expected to work relative to its predecessors.Agricultural and Food Policy,
Research Activities and Networks in CAIS Conferences for the Period of 1993- 2015: Social Network Analysis
No full textSince 1973 the Canadian Association for Information Science (CAIS/ACSI) has consecutively held 43 annual conferences. The purpose of this study is to better understand the research and collaborative activities in the community of CAIS conferences, based on a social network analysis (SNA) approach. A total of 827 papers from 778 authors have been presented in CAIS for the period of 1993 to 2015, in association with 209 different organizations and 25 countries. A component analysis that has been applied to the collaboration network has discovered research collaboration patterns. This study contributes to discovering collaborative research activities and formation through the CAIS conference and to the literature of the scientific collaboration in the LIS field.

Un total de 827 articles de 778 auteurs ont été présentés à l’ACSI dans la période 1993-2015, en association avec 209 organisations différentes et 25 pays. L’analyse des composantes du réseau de collaboration met en lumière l’existence de patrons de collaboration de recherche au sein de la communauté. Cette étude contribue à l’étude des activités de collaboration au sein des congrès de l’ACSI ainsi qu’à la littérature sur la collaboration scientifique dans le domaine BSI
Dynamic Econometric Models of Manitoba Crop Production and Hypothetical Production Impacts for CAIS
No full textThis study analyzes the impact of the Canadian Agriculture Income Stabilization (CAIS)program. The study begins with a specification of dynamic crop production that decomposes static short run crop acreage allocation decisions and dynamic crop yield affects. The modelling framework accommodates risk aversion, price uncertainty, and applies recent aggregation theory to aggregate weather data. Using this framework an analytical model of the impacts of CAIS on crop production is developed. Hypothetical impacts of are simulated using an aggregate Manitoba data set. The results show that CAIS has a substantial impact on the shadow prices of both inputs and outputs. These shadow price effects resulted in a 4 percent increase in long run wheat and barley yields and a 2 percent increase for canola. CAIS has a small impact on nominal wealth but the impacts depend on the properties of producers’ risk preferences. With constant relative risk aversion there is a wealth effect which in turn affects production decisions.Canada, CAIS, risk, crop, production, Agricultural and Food Policy, International Relations/Trade, Production Economics, Risk and Uncertainty,
Making Invisible College Visible: Comparing ASIS&T and CAIS Annual Conferences as Two Scientific Communities
No full textThis paper reports an ongoing research that conceptualizes two major LIS academic conferences in NorthAmerica as two dynamic scientific communities: ASIS&T Annual Meetings and CAIS AnnualConferences. Using a social network analysis approach, this study compares and visualizes how these twoscientific communities have been structured and organized between 1993 and 2015
A unified framework for producing CAI melting, Wark-Lovering rims and bowl-shaped CAIs
No full textInternational audienceCalcium-Aluminium inclusions (CAIs) formed in the Solar system, some 4567 million years ago. CAIs are almost always surrounded by Wark-Lovering rims (WLRs), which are a sequence of thin, mono/bi-mineralic layers of refractory minerals, with a total thickness in the range of 1-100 microns. Recently, some CAIs have been found that have tektite-like bowl-shapes. To form such shapes, the CAI must have travelled through a rarefied gas at hypersonic speeds. We show how CAIs may have been ejected from the inner solar accretion disc via the centrifugal interaction between the solar magnetosphere and the inner disc rim. They subsequently punched through the hot, inner disc rim wall at hypersonic speeds. This re-entry heating partially or completely evaporated the CAIs. Such evaporation could have significantly increased the metal abundances of the inner disc rim. High speed movement through the inner disc produced WLRs. To match the observed thickness of WLRs required metal abundances at the inner disc wall that are of order 10 times that of standard solar abundances. The CAIs cooled as they moved away from the protosun, the deduced CAI cooling rates are consistent with the CAI cooling rates obtained from experiment and observation. The speeds and gas densities required to form bowl-shaped CAIs are also consistent with the expected speeds and gas densities for larger, ˜1 cm, CAIs punching through an inner accretion disc wall
Static computer-aided implant surgery (s-CAIS) analysing patient-reported outcome measures (PROMs), economics and surgical complications: A systematic review.
No full textOBJECTIVE
To systematically evaluate the scientific literature for patient-reported outcome measures (PROMs) in static computer-aided implant surgery (s-CAIS).
METHODS
A PICO strategy was executed using an electronic (MEDLINE, EMBASE, CENTRAL), plus manual search up to 15-06-2017 focusing on clinical studies investigating s-CAIS with regard to patients' pain & discomfort, economics and/or intra-operative complications. Search strategy was assembled from multiple conjunctions of MeSH Terms and unspecific free-text words. Assessment of risk of bias in selected studies was made at a "trial level" applying the Cochrane Collaboration Tool and the Newcastle-Ottawa Assessment Scale, respectively.
RESULTS
The systematic search identified 112 titles. Seventy abstracts were screened, and 14 full texts were included for analysis. A total of 484 patients were treated with s-CAIS for placement of 2,510 implants. Due to the heterogeneity of the included studies, meta-analyses could not be performed.
CONCLUSIONS
The number of identified studies investigating s-CAIS for PROMs was low. Scientifically proven recommendations for clinical routine cannot be given at this time; however, the number of clinical complications with s-CAIS seems to be negligible and comparable to conventional implant surgery. s-CAIS may offer a beneficial treatment option in edentulous cases if a flapless approach is applicable. Nevertheless, the economic effects in terms of time efficiency and treatment costs are unclear. Clinical investigations with well-designed RCTs investigating PROMs with standardized parameters are compellingly necessary for the field of s-CAIS
A risk management approach to CAIS development
No full textThe proposed DoD standard Common APSE Interface Set (CAIS) was developed as a framework set of interfaces that will support the transportability and interoperability of tools in the support environments of the future. While the current CAIS version is a promising start toward fulfilling those goals and current prototypes provide adequate testbeds for investigations in support of completing specifications for a full CAIS, there are many reasons why the proposed CAIS might fail to become a usable product and the foundation of next-generation (1990'S) project support environments such as NASA's Space Station software support environment. The most critical threats to the viability and acceptance of the CAIS include performance issues (especially in piggybacked implementations), transportability, and security requirements. To make the situation worse, the solution to some of these threats appears to be at conflict with the solutions to others
NEW TITANIUM ISOTOPE DATA FOR ALLENDE AND EFREMOVKA CAIs
No full textWe measured the titanium (Ti) isotope composition, i.e., 50Ti/47Ti, 48Ti/47Ti, and 46Ti/47Ti, in five calcium-rich-aluminum-rich refractory inclusions (CAIs) from the oxidized CV3 chondrite Allende and in two CAIs from the reduced CV3 chondrite Efremovka. Our data indicate that CAIs are enriched in 50Ti/47Ti and 46Ti/47Ti and are slightly depleted in 48Ti/47Ti compared to normal Ti defined by ordinary chondrites, eucrites, ureilites, mesosiderites, Earth, Moon, and Mars. Some CAIs have an additional 50Ti excess of 8ε relative to bulk carbonaceous chondrites, which are enriched in 50Ti by 2ε relative to terrestrial values, leading to a total excess of 10ε. This additional 50Ti excess is correlated with nucleosynthetic anomalies found in 62Ni and 96Zr, all indicating an origin from a neutron-rich stellar source. Bulk carbonaceous chondrites show a similar trend, however, the extent of the anomalies is either less than or similar to the smallest anomalies seen in CAIs. Mass balance calculations suggest that bulk Allende Ti possibly consists of a mixture of at least two Ti components, anomalous Ti located in CAIs and a normal component possibly for matrix and chondrules. This argues for a heterogeneous distribution of Ti isotopes in the solar system. The finding that anomalous Ti is concentrated in CAIs suggests that CAIs formed in a specific region of the solar system and were, after their formation, not homogeneously redistributed within the solar system. Combining the CAI data with improved model predictions for early solar system irradiation effects indicates that a local production scenario for the relatively short lived radionuclides can be excluded, because the production of, e.g., 10Be, 26Al, and 41Ca, would result in a significant collateral shift in Ti isotopes, which is not seen in the measured data. © 2009.
