加拿大乏燃料处置的研发工作

论述了加拿大从1974年至今的乏燃料地质处置的研发工作,并对2002年以后研发工作中的某些问题进行了较详细的介绍:加拿大核废物管理机构、加拿大第4个乏燃料处置方案——可调整的分期管理(APM)方案的产生、APM方案的特点及其实施的技术路线,以及今后5 a(2011～2015年)的战略计划.     

Lignites from the Plains region of Alberta,Canada—Part 2: Elemental geochemistry

Mineralogy and elemental concentration of two coal seams in Alberta, Canada, were determined using X-ray diffractometry and X-ray fluorescence (XRF). Minerals consist mainly of quartz and calcium minerals, the latter as calcite and vaterite, and oxalate (whewellite). Clay minerals are present as kaolinite, reflecting peat deposition in an acidic environment. Most elements in the coal show depletion compared to Clarke values. Some elements are associated with mineral matter (e.g., Ti, Ba, Si, Al, K, Mg, and Y) and increase with ash. Na, Mn, Sr, and Cu are associated with macerals. High phosphorous and strontium in one interval may be related to the high concentration of whewellite.     

中国与加拿大油菜籽价格的传递关系

基于2013年1月1日—2019年12月31日中国和加拿大油菜籽现货和期货价格的周度数据，运用单位根检验、约翰森协整检验、格兰杰因果检验和方差分解等方法，以国内油菜籽临储政策取消的预期目标为出发点，分析我国油菜籽临储政策取消前后中国与加拿大油菜籽价格的传递关系变化。结果表明：油菜籽临储政策取消之前，中国与加拿大油菜籽现货、期货价格之间不存在长期协整关系；油菜籽临储政策取消之后，加拿大油菜籽期货和现货价格对国内油菜籽期货和现货价格之间的传递关系愈加明朗。据此提出以下建议：利用好国际市场大环境的同时建立国内油菜籽价格预警信息联动机制；发挥国产油菜籽在国际市场中的品质优势和时间优势；尽快完善我国油菜籽期货合约以提高油菜籽期货市场的活跃度。

加拿大安大略省不动产公司土地买卖丑闻案暴露了三类作弊:翻滚图利,甜心蜜约和利益冲突。中国也会有类似现象。本文分析中国国情和提出一个处理办法。     

Conflict and childhood friendship in Taiwan and Canada.

The present study assessed cross-cultural differences in friendship characteristics among children (aged 8–9 yrs) from collectivist and individualist cultures. Same-sex dyads of Grade 3 and Grade 4 students in a middle-class suburb of Toronto, Canada (n?=?1,227) and students from a middle-class suburb of Taipei, Taiwan (n?=?965) reported on the presence of companionship, conflict, help, security, and closeness in their friendships. The analysis reveals that long-term stability rates for friendships were not significantly different between nations or between boys and girls. Companionship was a significant predictor of friendship continuation among students in Taiwan. Friends in Taiwan reported significantly less conflict in their relationships than did friends in Canada. There was also greater agreement among friends in Taiwan than in Canada on the presence of conflict in the friendship relationship. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The registration of psychologists in Canada.

A review of current statutes indicates that six provinces in Canada now have acts which provide for the registration of psychologists. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Friendship satisfaction in Korean and Canadian university students.

Two studies explored predictors of friendship satisfaction (viewed here as high positive feelings and low negative feelings) in Korean and Canadian university students. Study 1 investigated friendship functions and conflict-resolution styles; Study 2 investigated if cross-cultural resolution differences in friendship expectations and collectivism account for observed differences in friendship variables. Canadian students fulfilled more friendship functions, and Korean students reported more asymmetrical conflict management, but the differences were generally not significant after controlling for friendship expectations and collectivism. In both countries, friendship satisfaction was similarly associated with fulfillment of friendship functions and egalitarian conflict management.

Moniliformin in barley inoculated with Fusarium avenaceum

To assess production of the mycotoxin moniliformin, inoculation trials with four barley cultivars and local isolates of Fusarium avenaceum were performed at two different experimental farms in southern Manitoba, Canada, during 1997-99. In the 1997 study, moniliformin was detected in 11 of 16 barley rows at levels between 0.19 and 1.62 mg g^-1, and F. avenaceum infection ranged from 10 to 57% in rows where the toxin was detected. In the 1998 study, moniliformin was detected in only three of 16 barley rows, with levels between 0.06 and 0.43 µg g^-1, and F. avenaceum infection between 16 and 39%. In the 1999 study, moniliformin was detected in 11 of 16 barley rows with levels between 0.09 and 0.42 µg g^-1, and F. avenaceum infection between 37 and 76%. In the 1997 trial, moniliformin was found in a single water-inoculated control row at 0.15 µg g^-1. The data suggest that in years of high rainfall and F. avenaceum infection, moniliformin is likely to be found in Manitoba barley.     

Legionella in domestic hot water systems

Outbreaks of Legionnaires' disease have been associated with extensive hot water systems such as those in hotels and hospitals. The extent to which domestic plumbing systems in Britain harbour legionellae is almost completely unknown.

The Electricity Research and Development Centre commissioned an investigation into the incidence of legionellae in 40 houses with hot water storage cylinders. Twenty houses had direct electric water heating, 20 had indirect water heating from a gas boiler.

To establish and identify the conditions conducive to colonization of domestic hot water systems by legionellae would require further, in depth, investigations of the all the factors involved.     

Letter to the Editor.

What follows is an open letter to the President and Directors, Canadian Psychological Association. This letter addresses the 1972 Survey of Psychologists in the United States and Canada, a survey which emanates from the APA and which has the cooperation of the Canadian Psychological Association. The author of this letter, Susan K. London, Ph.D. believes the willingness of the Board of Directors of CPA to commit Canadian psychologists--without any sort of approval from the CPA membership, which is within your legal rights, but which is nonetheless very disturbing morally--to this sort of thing demonstrates a naiveté if not downright disingenuousness. It is more than time for Canadian psychologists to recognize one of their blindspots. The ordinary Canadian psychologist is usually quite sensitive to political implications--except when it comes to psychology and the United States! When that subject comes up, the usual camouflage is invoked: professionalism, value-free science, the need to rationalize procedures, etc. The most common one, perhaps, is the notion that APA and American psychologists (in the United States and in Canada) only wish to be of help. The camouflage rather reminds me of the squid that emits quantities of ink in the face of danger. It is therefore an indication that the CPA Board of Directors are aware of danger, are in fact acting in full knowledge of that danger. The contradiction is blatant.
