Who Can Work Where: Reducing Barriers to Labour Mobility in Canada

Barriers to labour mobility in Canada remain a problem, even though Canadian governments have taken steps to reduce them. In the study, the author says Canada’s regulated professions and skilled trades, which represent about 11 percent of the workforce, face barriers to mobility that have negative implications for the country’s productivity, labour supply and future economic prospects. Like the rest of the world, Canada will face a labour crunch in the next 10 years. Unless Canada ensures that its professionals and skilled workers can work anywhere in the country, it could limit the ability to attract the people the economy needs.Economic Growth and Innovation, labour mobility, Agreement on Internal Trade (AIT), Labour Mobility Chapter

Heavy mineral stratigraphy of the Unayzah Formation and Basal Khuff Clastics (Carboniferous to Permian) of Central Saudi Arabia

A study of heavy mineral assemblages in the Unayzah Reservoir sandstones of central Saudi Arabia has identified successive changes in provenance signature. These define four heavy mineral units that are of regional extent and largely coincident with the four main depositional units defined by previous authors: Unayzah C, Unayzah B, Unayzah A and the Basal Khuff Clastics. Sandstone bodies with anomalous mineral signatures also occur, however, especially within the Unayzah B Member. These are attributed to local supply of sand from pre-Unayzah Paleozoic sandstones exposed on the Central Arabian Arch and on intrabasinal highs. The stratigraphic changes in mineralogy reflect successive developments in the geography and climate of the region and in the pattern of sand sourcing and transport. The Unayzah C sands and the majority of Unayzah B sands were derived from the south but whereas the southerly derived Unayzah C sands appear to have been derived from pre-existing mature sandstones, those of Unayzah B were sourced from a wider range of rock types including crystalline basement. This contrast is interpreted as indicating that a significant hiatus may separate the two units. The Unayzah B sands are also characterised by the common presence of apatite, indicating that the source rocks were relatively unweathered. This observation is compatible with the glacial origin attributed to many of the Unayzah B sediments. A further change in provenance signature takes place at the base the newly recognised ‘un-named middle Unayzah member’, equivalent to the base of Unayzah A of previous authors. This is associated with the onset of red-bed sedimentation throughout the area. Unayzah A sedimentation was terminated by a fall in sea level that led to the formation of a widespread unconformity and to the development of deeply incised valleys along the western basin margin. In most of the study area this unconformity corresponds to the base of the Khuff Formation, but in the east of the area, where the succession is more complete, it is believed to occur within the Unayzah Formation, at a level equivalent to the base of the Upper Gharif Member of Oman. By identifying lateral and vertical changes in sand provenance, heavy mineral analysis provides an important additional tool in the stratigraphic analysis of the Permian sandstone succession of Saudi Arabia, both at the regional scale and wand at the scale of individual reservoir sandstone successions

Combined VSWIR/TIR Products Overview: Issues and Examples

The presentation provides a summary of VSWIR data collected at 19-day intervals for most areas. TIR data was collected both day and night on a 5-day cycle (more frequently at higher latitudes), the TIR swath is four times as wide as VSWIR, and the 5-day orbit repeat is approximate. Topics include nested swath geometry for reference point design and coverage simulations for sample FLUXNET tower sites. Other points examined include variation in latitude for revisit frequency, overpass times, and TIR overlap geometry and timing between VSWIR data collections

Senoi Dream Praxis

Anthropologists who work with the people Kilton Stewart called ‘senoi’ agree that his account of how those people talk about and use dreams is rather idealized. The inaccuracies seem to stem from unconscious but systematic methodological biases which Domhoff and I have discussed at length elsewhere (Ed. Note: See note at end of article). The following account of Senoi dream praxis draws on discussions I have had with other anthropologists, notably Geoffrey Benjamin of the University of Singapore and Clay Robarchek of the University of California. Senoi themselves, however, supplied most of the information, during conversations with me while I was Living with them in 1961—1963 and 1975. This article is therefore a critique neither of Stewart’s work nor of the therapy he pro-moted, merely a presentation of dream theory in Malaya

The preparation of elementary fluorine and its reactions with certain organic compounds

This work had two main objectives: (1) The construction of an electrolytic cell for the production of fluorine, (2) the preparation of some organic compounds containing fluorine. This research was undertaken because of the growing importance of fluorine chemistry, particularly in the field or organic chemistry. Due to the extreme activity of fluorine, it is theoretically possible to prepare many times more fluorine-containing organic compounds than there are known organic compounds today. It has been predicted that fluorine-containing products will be developed to include new and useful dyes, plastics, pharmaceuticals, lubricants, tanning agents, metal fluxes, fumigants, insecticides, germicides, fire extinguishers, solvents, fireproofing compounds, heat transfer media, and other beneficial products. Use may also be made of the volatility of certain fluorides to effect separations of contaminating elements from ores by volatilization. --Introduction, page 1
