This paper aims to report the attempts for predicting “on-the-fly” flow distortion in the engine entrance plane of a highly curved S-duct from wall static pressure measurements. Such a technology would be indispensable to trigger active flow control devices to mitigate the intense flow separations which occur in specific flight conditions.

Evaluation of different reconstruction algorithms is performed on the basis of data extracted from a Zonal Detached Eddy Simulation (ZDES) of a well-documented S-Duct (Garnier et al., AIAA J., 2015). Contrary to RANS methods, such a hybrid approach makes unsteady distortions available, which are necessary information for reconstruction algorithm assessment.

The best reconstruction accuracy is obtained with the artificial neural network (ANN) but the improvement compared to the classical linear stochastic estimation (LSE) is minor. The different inlet distortion coefficients are not reconstructed with the same accuracy. KA2 coefficient is finally identified as the more suited for activation of the control device.

LSE and its second-order variant (quadratic stochastic estimation [QSE]) are applied for reconstructing instantaneous stagnation pressure in the flow field. The potential improvement of an algorithm based on an ANN is also evaluated. The statistical link between the wall sensors and 40-Kulite rake sensors are carefully discussed and the accuracy of the reconstruction of the most used distortion coefficients (DC60, RDI, CDI and KA2) is quantified for each estimation technique.

The year 1848 is considered by historians as a political and economic turning point in France: a major political crisis took place in the form of the February Revolution, accompanied by extensive financial troubles for the French government. The economists of that time actively debated the economic causes and consequences of the crisis. This chapter is devoted to the analysis of these financial controversies in French economic thought around 1848. If the political and philosophical debates of 1848 between the liberals and the socialists are quite well known by historians of economic thought, their financial side has been relatively neglected. According to the authors of this chapter, it is nevertheless of great interest to examine the liberal and socialist ideas of that time. This chapter aims to investigate this little-studied question by raising three main issues: the first one consists of presenting the different diagnoses of the 1848 financial crisis from socialist and liberal viewpoints. Second, it proposes an analysis of the content of theoretical controversies about ways to overcome the financial troubles, particularly regarding the trade-off between taxation and debt. Lastly, it emphasizes the role of this period for the subsequent constitution of a financial orthodoxy in France.

To explicate the qualities of cooperation among leaders and their organizations during crisis, we studied the response to the 2013 Boston Marathon bombings. Through interviews and analysis, we discovered leaders successfully overcame obstacles that typically undermine collective crisis response. Qualitative analysis revealed five guiding behavioral principles that appeared to stimulate effective inter-agency leadership collaboration in high stakes. We draw upon concepts of collective leadership and swarm intelligence to interpret our observations and translate the findings into leader practices. We focus on replicable aspects of a meta- phenomenon, where collective action was greater than the sum of its parts; we do not evaluate individual leader behavior. Our findings provide a starting point for deeper exploration of how to bolster public safety by catalyzing enhanced inter-agency leadership behavior.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

SOCIAL scientists have not yet been able to formulate any general laws about behaviour in industry that are capable of broad application. In recent years, however, they have made many useful case studies of which the one just published by the Department of Scientific and Industrial Research is typical. It is an approach to the problem which can do much to increase the understanding of the way in which people react to common industrial situations.

Using data from the Children of Immigrants Longitudinal Study, this study examines the structural relationships between negative school social relationships, school safety, educational expectation, and academic achievement of Latino immigrant students. Results from multilevel structural equation modeling show that discrimination, unhelpful school social relationships, and experiences of unsafe school environments influence Latino immigrant adolescents’ academic achievement indirectly and directly through their educational expectations. Specifically, this study explores how noncognitive and contextual factors embedded in different structural layers of school organization influence Latino immigrant adolescents’ academic achievement. It draws attention to the impact of negative school factors such as discriminatory and unsupportive school social relationships, and negative and unsafe school structures that undermine school life. Based on our findings, we argue that as Latino immigrant students internalize negative experiences from their school experiences during the critical period of adolescence, such accumulated negative internalization may reinforce negative self-perceptions and inaccurate stereotypes. Not only discrimination but also other negative school features such as the absence of academic supporters, nonacademically oriented friends, and unsafe learning environments inhibit them from navigating positive school opportunities and ultimately, successful school achievement. Implications for the social organization of U.S. public secondary schools with a focus on Latino immigrant adolescents’ academic achievement are discussed.

To review and synthesize findings from peer-reviewed research related to students’ sources of ideas for writing, and instructional dimensions that affect students’ development of ideas for composition in grades K-8.

The ideas or content expressed in written composition are considered critical to ratings of writing quality. We utilized a Systematic Mixed Studies Review (SMSR) methodological framework (Heyvaert, Maes, & Onghena, 2011) to explore K-8 students’ ideas and writing from a range of theoretical and methodological perspectives.

Students’ ideas for writing originate from a range of sources, including teachers, peers, literature, content area curriculum, autobiographical/life experiences, popular culture/media, drawing, and play. Intertextuality, copying, social dialogue, and playful peer interactions are productive strategies K-8 writers use to generate ideas for composing, in addition to strategies introduced through planned instruction. Relevant dimensions of instruction include motivation to write, idea planning and organization, as well as specific instructional strategies, techniques, and tools to facilitate idea generation and selection within the composition process.

A permeable curriculum and effective instructional practices are crucial to support students’ access to a full range of ideas and knowledge-based resources, and help them translate these into written composition. Instructional practices for idea development and writing: (a) connect reading and writing for authentic purposes; (b) include explicit modeling of strategies for planning and “online” generation of ideas throughout the writing process across genre; (c) align instructional focus across reading, writing, and other curricular activities; (d) allow for extended time to write; and (e) incorporate varied, flexible participation structures through which students can share ideas and receive teacher/peer feedback on writing.

With growing interest in the uses of hedonic technologies and gamification in system design, the concept of cognitive absorption (CA) has become increasingly salient in the information systems literature. However, little effort has been made to evaluate the research status and consolidate the current literature findings. To fill these research gaps, the authors conducted a literature review on CA. The authors then proposed an integrative framework that summarises the key elements of and variables related to CA and their relationships. The major findings of the study are discussed, and an agenda for future research is proposed.
