Most Canadian provinces have introduced legislation to require politicians of all ideological stripes to meet annual balanced budget (BB) targets. Critics of this type of legislation argue that it is unnecessary, confining, and subject to manipulation. We examine provincial balanced budget legislation before and after the Great Recession and argue that the response of provinces needs to be evaluated taking into account the multiple objectives of fiscal policy and the behavioural changes that the rules introduce, including creative non‐compliance. Rules should be evaluated on their ability to contribute to good fiscal governance rather than on their stringency.  相似文献

Forensic DNA interpretation is transitioning from manual interpretation based usually on binary decision‐making toward computer‐based systems that model the probability of the profile given different explanations for it, termed probabilistic genotyping (PG). Decision‐making by laboratories to implement probability‐based interpretation should be based on scientific principles for validity and information that supports its utility, such as criteria to support admissibility. The principles behind STRmix? are outlined in this study and include standard mathematics and modeling of peak heights and variability in those heights. All PG methods generate a likelihood ratio (LR) and require the formulation of propositions. Principles underpinning formulations of propositions include the identification of reasonably assumed contributors. Substantial data have been produced that support precision, error rate, and reliability of PG, and in particular, STRmix?. A current issue is access to the code and quality processes used while coding. There are substantial data that describe the performance, strengths, and limitations of STRmix?, one of the available PG software.  相似文献

This article provides a case study on embedding employability skills into law courses at one higher education institution. The aim of the project was to further embed employability skills within curriculum delivery as part of a holistic student skills development strategy. The authors used the four-stage process, suggested by the Higher Education Academy’s Framework on Embedding Employability in Higher Education to design the project: defining employability, reviewing and mapping current employability skills, prioritising actions and measuring impact. The authors draw out three ways in which the project has wider potential relevance. From an educational theory perspective, the project represents a way to embed employability skills in a Framework for Higher Education Qualifications level appropriate way, through reference to Biggs’ taxonomy of learning. For higher education institutions, the project is particularly topical in light of the rapidly changing regulatory landscape that is becoming increasingly skills focused in nature. It is suggested that embedding employability in law courses now will assist future institutional engagement with the potentially new route to qualifying as a solicitor through the Solicitors Qualifying Examination. Individual law teachers also reported benefits to embedding employability skills in tutorial sessions from a classroom management perspective.  相似文献

Abstract

The former migrant camp at Benalla (1949–1967) is one of the least publicly remembered of twenty-three similar centres which provided temporary housing for non-British arrivals in post-war Australia. One of Benalla’s keenest observers saw it as ‘a sad and tragic camp where widows and single mothers were sent’. Another claimed that, as a consequence, it had ‘peculiar difficulties’. The camp ended miserably with the forced relocation of several widows and their families who had been resident in Benalla’s ‘short-term accommodation’ ever since their arrival in Australia seventeen years before. Migrant camps, like Benalla, are difficult heritage places. They raise embarrassing questions about discrimination against the non-British, family separation, forced movement and the inadequacy of support services for the most vulnerable. Benalla has hitherto seen no grand camp reunion, plaque, memorial, public history or heritage listing which raises questions about the perceptions and experiences of the facility while it operated and broader questions about remembering and heritage-making. Benalla was a unique migrant centre and as such provides rare insight into the place of single refugee women and their children within the frames of national/state, local and migrant family heritage.  相似文献

Successful mitochondrial DNA (mtDNA) forensic analysis depends on sufficient quantity and quality of mtDNA. A real-time quantitative PCR assay was developed to assess such characteristics in a DNA sample, which utilizes a duplex, synthetic DNA to ensure optimal quality assurance and quality control. The assay's 105-base pair target sequence facilitates amplification of degraded DNA and is minimally homologous to nonhuman mtDNA. The primers and probe hybridize to a region that has relatively few sequence polymorphisms. The assay can also identify the presence of PCR inhibitors and thus indicate the need for sample repurification. The results show that the assay provides information down to 10 copies and provides a dynamic range spanning seven orders of magnitude. Additional experiments demonstrated that as few as 300 mtDNA copies resulted in successful hypervariable region amplification, information that permits sample conservation and optimized downstream PCR testing. The assay described is rapid, reliable, and robust.  相似文献
