Canadian real estate developers said that the flowing in of Chinese money will keep housing markets stable in Vancouver. The city was recently ranked the second least affordable in the world by Demographia’s International Housing Affordability survey. Colin Bosa,CEO of Bosa Properties,said that as long as the Chinese continue to move to British Columbia,markets will remain stable."They like it in British Columbia because it’s safe and they’re accepted here,"Bosa said."There is a good quality of life with universal health care and good schools."Vancouver is British Columbia’s largest city and known for hosting the 1986 Expo,2010 相似文献

ABSTRACTThis study used data from an in-person paper-and-pencil climate survey administered to students in a random sample of classes at a four-year southeastern university. Respondents (N = 248) left unsolicited qualitative comments on the survey (N = 540). Grounded theory was used to determine if themes existed among them. Questions on school safety, rape myths, and resource knowledge prompted the most unsolicited comments (n = 111). Comments centered on clarification or opinions. Given the survey was adapted from a prior climate survey, unsolicited comments highlight areas of clarification and improvement for future iterations of climate surveys. Implications for campus safety are discussed. 相似文献

Literature on Canada-United States (US) counter-terrorism (CT) cooperation from the early 2000s presumed that Canadian CT policy was driven by US security imperatives and fear, leaving little room for Canada to develop its own path in fighting terrorism. It presumed that: the Canadian government was more worried about the US reaction to terrorism than terrorism itself; Canadian security policy sought to be “separate but cooperative”; and Canadian policy was informed by “wise” understandings of the US. We argue these assumptions no longer hold. Since 2011, with the rise of the Islamic State and foreign fighter activity, the Canadian government took independent steps to address national security concerns in a multilateral environment. We use process tracing to track evolutions in the Passenger Protect Program (Canada's “no-fly list” policy), showing how Canada has increasingly asserted agency in response to violent extremism. It suggests the prior scholarly consensus on the US role in Canadian CT policy must be rethought. 相似文献

While the Class Action Fairness Act (CAFA) establishes a bright-line jurisdictional amount in controversy for removing cases from state to federal court, calculating that quantitative threshold in practice is a fraught and heavily litigated exercise. This article examines removals under CAFA to show the substantial lack of clarity in how state-law causes of action and damage claims interact to reach the jurisdictional threshold. It compiles cases illustrating the challenges surrounding removal litigation that flow from these uncertainties, particularly in how the structure of CAFA incentivizes defendants to chain together tail-event precedent to inflate theoretical amounts in controversy. It then applies a Coasean analysis to suggest these uncertainties impede efficient resolutions to litigation. Finally, it suggests a series of practical amendments to CAFA and its interpretive case law that would provide clarity, decrease forum-selection litigation, and enhance the efficacy of class litigation. 相似文献

The HSP70 superfamily is a reliable biomarker for hyperthermia, hypothermia and hypoxia. The Enzyme-linked Immunosorbent Assay (ELISA) respectively immunohistochemically staining methods are the typically used techniques for the quantification of those proteins. As the costs for reagents and devices as well as the work schedule of these methods are immense it was the goal of our study to develop an easy and reliable method to quantify the concentration of specific proteins. We established a procedure to measure the relative concentration of proteins fixed on ROTI(?) PVDF membranes via Western blot, calculating the relative protein concentration in dependency to the grey scale index of the normalized and digitalized pictures of the bands on the blots. 相似文献

Sudden cardiac deaths are common within the community. They also constitute a substantial part of daily pathologic and forensic case work. However, macroscopic myocardial findings indicating acute ischemia are often absent. Then, diagnosis is based on coronary status in combination with indirect signs of acute cardiac failure. We present a case of sudden cardiac death where diagnosis was based on cardiac postmortem magnetic resonance imaging (pmMRI) findings already prior to autopsy: the heart's anterior basal ventricular septum showed hypointensities in T2-weighted images that raised suspicion of peracute ischemia. The lumen of the left anterior descending artery (LAD) exhibited a lack of otherwise discernible postmortem sedimentation of cellular blood components. Instead of a sharp border between serum and erythrocytes a homogeneous signal was seen within the narrowed lumen of the beginning LAD over a length of 1cm. Based on this, a thrombotic occlusion was assumed. Subsequent autopsy confirmed peracute septal myocardial ischemia secondary to a thrombotic occlusion of the LAD as concluded from the pmMRI. 相似文献

Understanding the developmental precursors of juvenile violent sex offending can contribute to the promotion of effective early intervention and prevention programs for high-risk children and youth. However, there is currently a lack of research on the early characteristics of adolescents who commit violent sex offenses. Drawing on the literature regarding the generalist and specialist positions of criminal behavior, the aim of the present study was to compare childhood risk factors for three groups of juvenile offenders: (a) pure sex offenders (PSO; n = 28); (b) violent non-sex offenders (VNSO; n = 172); and (c) versatile violent sex offenders (VVSO; n = 24). Nineteen risk factors comprising four life domains (individual, family, peer, and school) were identified from a file review. Three hierarchical logistic regression analyses examined associations between risk factors and offender groups. The results reflected the underlying heterogeneity of the sample, offering support for both the specialist and generalist positions of criminal behavior. PSOs differed from VNSOs on the basis of higher odds for precocious sexual behavior. Second, VVSOs differed from VNSOs on the basis of higher odds for precocious sexual behavior, criminal family members, and an adolescent mother, as well as lower odds for poor school behavior. Third, PSOs were marginally more likely to have engaged in early overt antisocial behavior compared with VVSOs. Fourth, many of the childhood risk factors examined were not associated with any offender group. In conclusion, VVSOs appeared to differ on the greatest number of risk factors from VNSOs, suggesting that VVSOs share a more similar developmental pathway with PSOs. The prevention and future research implications of these findings are discussed. 相似文献
