This article focuses on the evolving nature of the foreign policy of the European Union (EU) towards Brazil, which gained momentum and became more dynamic and denser after the establishment of a formal strategic partnership (SP) in 2007. It provides a historical overview of the institutional relations between Brussels and Brasília, before proceeding with an analysis of the main drivers behind this novel development. The study goes on to offer a critical examination of the implementation of the EU–Brazil SP by casting light on both its major achievements and the challenges it has faced. It concludes that the establishment of a formal strategic partnership with Brazil has contributed to the strengthening of the EU’s globally oriented partnership policy and ultimately to the incremental empowerment of the EU necessary to the assertion of its values, objectives and interests on the international stage. 相似文献

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners. 相似文献

ABSTRACTThe questioning practices of Canadian lawyers were examined. Courtroom examinations (N?=?91) were coded for the type of utterance, the assumed purpose of the utterance, and the length of utterance. Results showed that approximately one-fifth of all utterances were classified as productive for gathering reliable information (i.e. open-ended, probing); less than one percent of all utterances were open-ended. Direct examinations contained more closed yes/no, probing, and open-ended questions. Cross-examinations contained more leading and clarification questions, and opinions. Moreover, cross- (vs. direct) examinations contained more questions with a ‘challenging the witness’ purpose. The longest utterances were opinions, followed by multiple and forced-choice questions. The longest answers were in response to open-ended questions, followed by multiple and probing questions. Implications for the truth-seeking function of the judiciary are discussed. 相似文献

AbstractThe goal of this special issue is to highlight the importance of unconventional social policies, theorize their development in comparison with traditional welfare state accounts and outline a new research agenda. In this introduction to the special issue, the editors present the concept of social policy by other means as encompassing two kinds of unconventional social policy (from the point of view of mainstream comparative research): First, functional equivalents to formal systems of social protection and, second, non-state provision of benefits. The concept builds upon a sizeable, but fragmented literature in comparative welfare state research. While numerous examples demonstrate that social policy by other means is more pervasive in both OECD and non-OECD countries than often acknowledged, a brief survey of the top 20 articles in the field reveals that this fact is not sufficiently reflected in the academic literature. With reference to both existing studies and the contributions to this special issue, the editors go on to explore (1) the different forms of social policy by other means, (2) explanatory theories and (3) their effectiveness in terms of social outcomes. They close by outlining a research agenda. 相似文献

Police identification of people experiencing mental illness is usually based on either the person having an official contact history with police or through observing behavioural indicators commonly associated with mental illness during an encounter. Police have voiced concerns with their ability to identify and respond to people experiencing mental illness in a timely way and report that they commonly resort to more coercive tactical options to resolve encounters. The present study employed a mixed method design to examine 286 police use of force incidents to investigate the association between force used on and by offenders displaying irrational-unstable behavioural characteristics. The irrational-unstable offenders were two times more likely to be perceived by police to have an apparent mental disorder and almost four times more likely to have a known mental health history; one in six had an official record of contact with mental health services. There were few differences in police and offender use of force, considering force as both a categorical and a continuous variable, while incident-level comparisons suggested that police force was generally proportional to offender resistance. Implications are discussed in terms of the need to redress limitations with the traditional police approach style. 相似文献
