Since 2006, hundreds of communities in Canada have produced Integrated Community Sustainability Plans, based on a four-pillar model of sustainability and developed in consultation with residents and stakeholders. These community-based experiments have developed models, knowledge, and insights about the place of culture in local sustainability. Both conceptual thinking and planning practices regarding the role of culture in sustainable communities were at an embryonic stage when these initiatives took place. The discussions, plans, and implementation processes have advanced both theory and “leading edge” practices with regard to culture and community sustainability, illustrating the importance of a robust relationship between research and practice.  相似文献

This article investigates the work of a Lebanese non-governmental organization (NGO) called the Committee of the Parents of the Missing and the Disappeared. Although the successive Lebanese governments, most political leaders, ex-militia leaders and ex-combatants did not want to help in revealing the truth about what had happened to the people who went missing during the Lebanese civil war of 1975, the Committee managed to mobilize the families of the missing people under one banner for more than 30 years and was successful in making the Lebanese government and the legal authorities take few but important decisions that favoured the cause of the families of the missing people. It managed to do so without being deterred by the social, political and economic challenges it faced and due to the ability of its leadership to clearly define the sources of contention it wanted to protest against and by selecting the protests methods that best serve its cause.  相似文献

In recent years, Azerbaijan–Israel relations have come to the foreground of politics in the Middle East and Caucasus region. Ties between Baku and Tel Aviv have been directly interlinked with their relations with Iran. The nature of the Azerbaijan–Israel partnership must be analysed in order to comprehend the balance of powers and energy security in the region. Even though there have been a number of works analysing the relationship by focusing on its role in regional military security, there is a gap in the discourse in terms of understanding the economic drivers of relations and the implications of the ties for regional energy security. Particular attention will be given to discussing Azerbaijan’s emerging role as a major energy producer that has already made a profound impact on the region as an ‘alternative’ to Iran in the aftermath of the recently imposed sanctions on Tehran's energy exports. It will be argued that the Azerbaijan–Israel relationship is built on solid economic grounds and it would be reasonable to expect the strength of the ties to be further intensified in the future. The article will also demonstrate that new developments in the energy security of the wider Middle Eastern region will affect the evolution of Azerbaijan–Israel ties and their rivalry with Iran in the next decade.  相似文献

Drunk driving is a serious threat to public safety. All available and appropriate tools for curbing this threat should be employed to their full extent. The handheld pre‐arrest breath test instrument (PBT) is one tool for identifying the alcohol‐impaired driver and enforcing drunk driving legislation. A set of data was evaluated (n = 1779) where the PBT instrument was employed in drunk driving arrests to develop a multivariate predictive model. When maintained and operated by trained personnel, the PBT provides a reasonable estimate of the evidential test result within the relevant forensic range (95% prediction interval:  ± 0.003 g/210 L). ROC analysis shows that a multivariate model for PBT prediction of the evidentiary alcohol concentration above versus below the legal limit of 0.08 g/210 L has excellent performance with an AUC of 0.96. These results would be of value in evidential hearings seeking to admit the PBT results in drunk driving trials.  相似文献

The extraction of DNA from human skeletal remains applied to forensic, and evolutionary studies do not exclude risks, which are to be evaluated when working with unique specimens that could be damaged or even destroyed. In the present study were evaluated several nondestructive methods for recovering DNA instead of the most currently used pulverization method. Three different procedures to access inside the dental pieces (occlusal perforation, cervical perforation, and cervical cut) have been compared with the aim of recovering as many cell remains as possible to carry out a DNA extraction. Given the DNA quantitation results, a method was proposed that consists of a cervical cut to facilitate the access to the pulp cavity and a subsequent filing of the root canals down to the apex of the dental root. This methodology allows the recovery of both mitochondrial and nuclear DNA, with the minimum deterioration for the dental pieces.  相似文献

The aim of this study was to analyze the differences between the handwritings of schizophrenia patients and healthy subjects in addition to the changes that occurred in schizophrenia patients' handwriting in response to the treatment. The test subjects were 29 schizophrenia patients and 29 healthy individuals with the same age, gender, and dominant hand. The changes in the handwritings were examined according to 14 different parameters. On the day of admittance, the percentage of extra letters was 16.7%, and after 7–10 days of hospitalization, it rose to 33.3%. The percentage of skipped words decreased from 29.2% to 16.7% after 7–10 days of hospitalization, and to 10% after 3 weeks. The letters written by schizophrenia patients are significantly larger in height and width compared to the control group. The schizophrenia patients showed a higher incidence of crossed-out letters, adding extra words, missing punctuation as well as missing words.  相似文献

Forced labour has been regulated since 1930 on the basis of the ILO Convention on Forced Labour, and since 1957 on the basis of the ILO Abolition of Forced Labour Convention. In 2000 forced labour was included as one form of exploitation covered by the UN Trafficking Protocol, which situated trafficking into a context of transnational organised crime. In 2014 the ILO adopted a Protocol on Forced Labour, making a link between trafficking and forced labour. The aim of this article is to explore how forced labour came to be regulated and defined in these four treaties. The 1930 ILO Convention came about in a specific historical and political context, yet the 1930 definition remains in use even though the interpretation of forced labour, particularly as it relates to trafficking, has changed. This article focuses on the issue of trafficking for the purpose of forced labour within the context of migration and labour exploitation, and discusses the relevance of historical definitions of forced labour in the current discourse that sees human trafficking mainly as a security threat. It argues that a rigid interpretation of forced labour is not always useful in understanding forms of labour exploitation, at least in a contemporary European migratory perspective. The article calls for a broad interpretation of forced labour, which takes into account also subtle forms of control and coercion.  相似文献
