Is the employed scholar free not to publish?:Limitations of disclosure rights in a comparative perspective

The control of works produced by academics in the course of their employment is a controversial issue. This paper examines the protection offered to employed scholars who do not want to publish their work because of the fear that premature dissemination would damage their academic reputation. The right not to publish of employed scholars has been analyzed considering Anglo-American copyright law on the one hand, and French legislation on the other. Irrespective of the differences between these jurisdictions, both positions allow labour conditions to restrict the right not to publish. On top of the comparison of three legal systems, this paper investigates the question of whether the limitations on the right of disclosure conflict with article 15, paragraph 1 c of the International Covenant on Economic, Social and Cultural Rights ICESCR. Both Anglo-American and French copyright law are not fully consistent with the protection of moral interests offered by the ICESCR. The reason is that it depends on the labour conditions whether there exists any obligation on academic employees to publish. In the absence of this obligation, the employed scholar enjoys the freedom to decide not to publish. ICESCR does not allow these limitations of disclosure rights since article 15, paragraph 1 c does not refer to working conditions

Thermal Brillouin noise observed in silicon optomechanical waveguide

Stimulated Brillouin scattering was recently observed in nanoscale silicon waveguides. Surprisingly, thermally-driven photon-phonon conversion in these structures had not yet been reported. Here, we inject an optical probe in a suspended silicon waveguide and measure its phase fluctuations at the output. We observe mechanical resonances around 8 GHz with a scattering efficiency of $10^{-5} \, \text{m}^{-1}$ and a signal-to-noise ratio of 2. The observations are in agreement with a theory of noise in these waveguides as well as with stimulated measurements. Our scheme may simplify measurements of mechanical signatures in nanoscale waveguides and is a step towards a better grasp of thermal noise in these new continuum optomechanical systems.Comment: 11 pages, 4 figure

Using EEG to Examine the Role of Attention, Working Memory, Emotion, and Imagination in Narrative Transportation

This paper presents a study using encephalography (EEG) to investigate consumer responses to narrative videos in energy efficiency social marketing. The purpose is to assess the role of attention, working memory, emotion, and imagination in narrative transportation, and how these stages of narrative transportation are ordered temporally. Design/methodology/approach Consumers took part in an EEG experiment during which they were shown four different narrative videos to identify brain response during specific video segments. Findings The study found that during the opening segment of the videos, attention, working memory, and emotion were high before attenuating with some introspection at the end of this segment. During the story segment of the videos attention, working memory, and emotion were also high, with attention decreasing later on but working memory, emotion, and imagination being evident. Consumer responses to each of the four videos differed. Practical implications The study suggests that narratives can be a useful approach in energy efficiency social marketing. Specifically, marketers should attempt to gain focused attention and invoke emotional responses, working memory, and imagination to help consumers become narratively transported. The fit between story object and story-receiver should also be considered when creating consumer narratives. Social implications Policy makers, and organisations who wish to promote pro-social behaviours such as using energy efficiently, or eating healthily should consider using narratives. Originality/value This research contributes to theory by identifying brain response relating to attention, working memory, emotion, and imagination during specific stages of narrative transportation. The study considers the role of attention, emotion, working memory, and imagination during reception of stories with different objects, and how these may relate to consumers' narrative transportation

Generalizing Refinement Operators to Learn Prenex Conjunctive Normal Forms

Inductive Logic Programming considers almost exclusively universally quantied theories. To add expressiveness, prenex conjunctive normal forms (PCNF) with existential variables should also be considered. ILP mostly uses learning with refinement operators. To extend refinement operators to PCNF, we should first do so with substitutions. However, applying a classic substitution to a PCNF with existential variables, one often obtains a generalization rather than a specialization. In this article we define substitutions that specialize a given PCNF and a weakly complete downward refinement operator. Moreover, we analyze the complexities of this operator in different types of languages and search spaces. In this way we lay a foundation for learning systems on PCNF. Based on this operator, we have implemented a simple learning system PCL on some type of PCNF.learning;PCNF;completeness;refinement;substitutions

What Happens in Vegas Stays on TripAdvisor? A Theory and Technique to Understand Narrativity in Consumer Reviews

Many consumers base their purchase decisions on online consumer reviews. An overlooked feature of these texts is their narrativity: the extent to which they tell a story. The authors construct a new theory of narrativity to link the narrative content and discourse of consumer reviews to consumer behavior. They also develop from scratch a computerized technique that reliably determines the degree of narrativity of 190,461 verbatim, online consumer reviews and validate the automated text analysis with two controlled experiments. More transporting (i.e., engaging) and persuasive reviews have better developed characters and events as well as more emotionally changing genres and dramatic event orders. This interdisciplinary, multimethod research should help future researchers (1) predict how narrativity affects consumers’ narrative transportation and persuasion, (2) measure the narrativity of large digital corpora of textual data, and (3) understand how this important linguistic feature varies along a continuum

Nonlinear optical interactions in silicon waveguides

The strong nonlinear response of silicon photonic nanowire waveguides allows for the integration of nonlinear optical functions on a chip. However, the detrimental nonlinear optical absorption in silicon at telecom wavelengths limits the efficiency of many such experiments. In this review, several approaches are proposed and demonstrated to overcome this fundamental issue. By using the proposed methods, we demonstrate amongst others supercontinuum generation, frequency comb generation, a parametric optical amplifier, and a parametric optical oscillator

PosterVote:expanding the action repertoire for local political activism

Online and digital technologies support and extend the action repertoires of localized social movements. In this paper we examine the ways by which digital technologies can support ‘on-the-ground ’ activist communities in the development of social movements. After identifying some of the challenges of deploying conventional voting and consultation technologies for activism, we examine situated political action in local communities through the design and deployment of a low-cost community voting prototype, PosterVote. We deploy PosterVote in two case studies with two local community organizations identifying the features that supported or hindered grassroots democratic practices. Through interviews with these communities, we explore the design of situated voting systems to support grassroots democratic practices and participation within an ecology of social action.
