This paper aims to present an experimental investigation of an active flow control solution mounted at rear of a sport utility vehicle (SUV) with the objective of drag reduction, thanks to a selection of flow control parameters leading to a pressure increase on the tailgate.

A flow control design of experiments was conducted with a pulsed jet system mounted on the top and sides of the rear window of the vehicle. The wall pressure, instantaneous velocity and drag were measured with this prototype in a wind tunnel. A dynamic modal decomposition (DMD) analysis of the pressure enables to describe the pressure fluctuations. Fluid dynamic computations show relation between pressure and velocity fields.

Measurements with this prototype in the wind tunnel revealed small improvements in drag for the best flow control configurations. This small benefit is because of the core of the upper span wise vortex further away from the rear window than the lower span wise vortex. These small improvements in drag were confirmed with pressure measurements on the rear window and tailgate. The DMD analysis of the surface pressure showed a low frequency pendulum oscillation on the lower area of the tailgate, linked with low velocity frequencies in the shear layers near the tailgate.

Experimental and numerical results show interest to increase pressure at bottom of the rear end of this SUV prototype. The dynamic description of the wall pressure shows importance of flow control solutions reducing pressure fluctuations at low frequencies in the lower area of the tailgate.

Culture shapes economic action and, as such, impacts economic life. Although there is a growing recognition amongst economists that culture matters, there is nothing approaching a universal agreement on how to incorporate culture into economic analysis. We provide a brief summary of how economists have discussed culture and then argue that Austrian School Economics is particularly well suited to contribute to our understanding of the relationship between culture and economic action. Indeed, Austrian economics has an advantage (1) because of its links to Max Weber’s approach to social science and (2) because of its emphasis on economics as a science of meaning. A Weber-inspired Austrian economics that stresses meaning, we argue, brings a focus on culture to the fore of economic analysis and opens the door for a progressive research program within cultural economics. Austrian economists can and have made significant contributions to our understanding of the relationship between culture and economic action. Moreover, we argue, explorations of the connection between culture and economic action can be a fruitful field of study within Austrian economics.

In vol. 6, 1976, of Advances in Librarianship, I published a review about relevance under the same title, without, of course, “Part I” in the title (Saracevic, 1976). [A substantively similar article was published in the Journal of the American Society for Information Science (Saracevic, 1975)]. I did not plan then to have another related review 30 years later—but things happen. The 1976 work “attempted to trace the evolution of thinking on relevance, a key notion in information science, [and] to provide a framework within which the widely dissonant ideas on relevance might be interpreted and related to one another” (ibid.: 338).

According to neo-institutional scholars, experts need to support decoupling, yet doing so may be more or less subjectively understandable for those who are employed as experts. The authors mobilize the phenomenological concept of the life-world as a lens for reconstructing how individuals give meaning to decoupling processes. Based on a hermeneutic analysis of a human resource management expert’s reflections on his activities, the authors highlight the subjective experience of decoupling as a process of solving tensions between an individual’s convictions and the relevances imposed by an organization. The authors conclude that a phenomenological lens enriches microfoundations debates by focusing on an individual’s learning within the framework of an imposed organizational reality.

Misinformation is a significant phenomenon in today's world: the purpose of this paper is to explore the motivations behind the creation and use of misinformation.

A literature review was undertaken, covering the English and Russian language sources. Content analysis was used to identify the different kinds of motivation relating to the stages of creating and communicating misinformation. The authors applied Schutz's analysis of motivational types.

The main types of motivation for creating and facilitating misinformation were identified as “in-order-to motivations”, i.e. seeking to bring about some desired state, whereas the motivations for using and, to a significant extent, sharing misinformation were “because” motivations, i.e. rooted in the individual's personal history.

The general model of the motivations underlying misinformation is original as is the application of Schutz's typification of motivations to the different stages in the creation, dissemination and use of misinformation.

As a rule during interviews, research and respondent share the same sense of reality. In contrast, how should researchers handle phantasmal narratives during interviews, or descriptions of events that are impossible according to natural law? In this chapter, I report on 38 interviews upon people who encountered ghosts, apply theoretical concepts (James, Schutz, Pollner, Blumer), and, through autoethnographic reflection, suggest three approaches (“debunking,” “distancing,” “detouring”) to handling such phantasmal narratives. I conclude that they are best handled by complete suspension of skeptical thought, concentrating on ghost beliefs and not ghost existence.

Social theory contains contributions related to the processes of semiosis. Between the subjective experience of intentional meanings and objectivized structure of meanings there is a sphere of meaningful interactions and collective actions. Arguments are presented that it is possible to integrate symbolic interactionist orientation and Durkheimian tradition in the study of social symbolism in the perspective of collective action approach and pragmatism. That allows going beyond the cognitive limitations inherited from phenomenological view on symbolism as manifested in the concepts of P. Berger and T. Luckmann about the social construction of reality. A model for a multidimensional analysis of social symbolism and its functions is proposed.

Phenomena are what we as researchers begin with, and to study phenomena is to appreciate how any determination of things and events always relates back to the context in which they appeared. Phenomenology is the study of such relations of appearance and the conditions of such relations. Appearance is an active rather than superficial condition, a constant bringing together of experiencing beings and experienced things (including sentient beings), in what the modern “father” of phenomenology Edmund Husserl called conditions of intentionality, and what his errant, one-time student Martin Heidegger called conditions of thrownness and projection. This chapter delves into the philosophical background of this mode of study, before opening up into consideration of, first, where phenomenology has been influential in organization studies, and, second, the potential of the approach. In so doing, we suggest much can be made of reorienting research in organization studies away from an entitative epistemology in which things are seen in increasingly causally linked, detailed isolation, and toward a relational epistemology in which what exists is understood in terms of its being experienced within everyday lives.
