Journalism students in The Netherlands: profile, motivation and role perception The general profile of the Dutch journalism student that emerges from the survey is quite consistent with international research. Using creativity and writing skills in a professional way are stronger motivations than the wish to contribute to democracy. Dutch students consider journalists as impartial providers of news (analysis) and stimulators of public debate. The watchdog role seems to be less popular. Striking is the conclusion that Dutch journalism students are not so much driven by idealistic motives, but merely personal interests. Only MA students who value the watchdog role of the media, stick to their idealistic motive. Feminization of the profession also reflects in training and education. As digital natives, with a strong focus on social media, we expect this new generation of journalists to search and find methods to avoid or fight the negative aspects of social media such as tunnel vision and fake news.

Prior to the nineteenth century, those who are now regarded as scientists were referred to as natural philosophers. With empiricism, science was claimed to be a superior form of knowledge to philosophy, and natural philosophy was marginalized. This claim for science was challenged by defenders of natural philosophy, and this debate has continued up to the present. The vast majority of mainstream scientists are comfortable in the belief that through applying the scientific method, knowledge will continue to accumulate, and that claims to knowledge outside science apart from practical affairs should not be taken seriously. This is referred to as scientism. It is incumbent on those who defend natural philosophy against scientism not only to expose the illusions and incoherence of scientism, but to show that natural philosophers can make justifiable claims to advancing knowledge. By focusing on a recent characterization and defense of natural philosophy along with a reconstruction of the history of natural philosophy, showing the nature and role of Schelling’s conception of dialectical thinking, I will attempt to identify natural philosophy as a coherent tradition of thought and defend it as something different from science and as essential to it, and essential to the broader culture and to civilization.

The flashed face distortion effect is a phenomenon whereby images of faces, presented at 4–5 Hz in the visual periphery, appear distorted. It has been hypothesized that the effect is driven by cortical, rather than retinal, components. Here, we investigated the role of peripheral viewing on the effect. Normally sighted participants viewed the stimulus peripherally, centrally, and centrally with a blurring lens (to match visual acuity in the peripheral location). Participants rated the level of distortion using a Visual Analogue Scale. Although optical defocus did have a significant effect on distortion ratings, peripheral viewing had a much greater effect, despite matched visual acuity. We suggest three potential mechanisms for this finding: increased positional uncertainty in the periphery, reduced deployment of attention to the visual periphery, or the visual crowding effect.

Psychoanalysis, and especially the work of Jacques Lacan, has not been adequately utilized within organization studies. This paper argues that Lacan's teaching has the potential to enrich discussions within this field and to suggest fruitful orientations for future research. Analysing some of the central concepts and theoretical logics introduced by Lacan (such as lack, desire, the symbolic, enjoyment and fantasy), it explores the desire behind identity construction (agency), the reliance of this desire on processes of subjection to the socio-symbolic order (structure), as well as the limits marking both these domains. It argues that Lacanian theory can illuminate the (negative) dialectic between subject and organized Other and account for obedience and attachment to organized frameworks of social life in two ways: first, by focusing on the symbolic presuppositions of authority and power; and, second, by exploring the role of fantasy and enjoyment in sustaining them and in neutralizing resistance.

Australian bushfires have repeatedly killed many people and caused severe damage. Previous studies have identified direct flame contact and radiant heat as the main cause of fatalities. The role of screens to limit the radiation exposure of an object by a fire on the opposite side of the screen is well-known, but still it has not been experimentally quantified. A screen between a radiation source and an object divides the radiant heat flux (RHF) into two parts. The first part is the direct RHF (DRHF) that passes directly through the screen without any interaction. The second part is indirect RHF (IRHF), which includes both emitted and reflected RHFs by the heated screen. This experimental study deals with the DRHF, which is dependent on the screen porosity and is independent of the material composition or the surface quality of the screen. The experimental results of four square-cell, plain woven screens, with porosities ranging from 41% to 66%, show that the passing ratios (PRs) of DRHF through screens are less than those suggested by their porosity. Four empirical equations have been developed to determine the PR of the direct radiation through screen and the tunnel vision angles of the screens.

This paper provides two demonstrations that highlight the importance of peripheral vision issues in system design. The first demonstration concerns the ability of the visual system to detect motion, while the second addresses the impact of reduction of visual field on the perception of optical flow data. Educators can use these demonstrations as the basis for discussions about the design implications for warning displays, attention gathering devices, optical flow, off-axis accidents, aging, attention, and night vision goggles. These demonstrations can be used at both the undergraduate and graduate levels. Relevant research findings are also discussed, and references for further exploration of the topics are provided.
