The social media paradox:an intersection with freedom of expression and the criminal law

This article begins by setting out the human rights provisions that apply to social media expression. It then provides insight into the part social media plays within our society by analysing the social media landscape and how it facilitates a ‘purer’ form of expression. The social media paradox is explored through the lens of current societal issues and concerns regarding the use of social media and how these have manifested into litigation. It concludes by analysing the tension that the application of an array of criminal legislation and jurisprudence has created with freedom of expression, and whether this can successfully mitigated by the Director of Public Prosecution’s Interim Guidelines.

Microarray analysis of expression of cell death-associated genes in spinal cord cells with cyclic tensile strain

Previous studies have described alterations in gene expression following spinal cord injury, but this response to mechanical stimuli is difficult to investigate in vivo. Therefore, we have investigated the effect of cyclic tensile strain on cultured spinal cord cells from E15 Sprague-Dawley rats. Microarray analysis of gene expression and categorization of identified genes were performed using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) systems. The application of cyclic tensile strain reduced the viability of cultured spinal cord cells significantly in a dose- and time-dependent manner. GO analysis identified candidate genes related to apoptosis (44) and to response to stimulus (17). KEGG analysis identified changes in the expression levels of 12 genes of the mitogen-activated protein kinase (MAPK) signaling pathway, which were confirmed to be upregulated and validated by RT-PCR analysis. Spinal cord cells undergo cell death in response to cyclic tensile strain, which were dose- and time-dependent, with upregulation of various genes, in particular of the MAPK pathway.

Effective forms of market orientation across the business cycle:a longitudinal analysis of business-to-business firms

Macroeconomic developments, such as the business cycle, have a remarkable influence on firms and their performance. In business-to-business (B-to-B) markets characterized by a strong emphasis on long-term customer relationships, market orientation (MO) provides a particularly important safeguard for firms against fluctuating market forces. Using panel data from an economic upturn and downturn, we examine the effectiveness of different forms of MO (i.e., customer orientation, competitor orientation, interfunctional coordination, and their combinations) on firm performance in B-to-B firms. Our findings suggest that the impact of MO increases especially during a downturn, with interfunctional coordination clearly boosting firm performance and, conversely, competitor orientation becoming even detrimental. The findings further indicate that both the role of MO and its most effective forms vary across industry sectors, MO having a particularly strong impact on performance among B-to-B service firms. The findings of our study provide guidelines for executives to better manage performance across the business cycle and tailor their investments in MO more effectively, according to the firm's specific industry sector.

A seismic shift? An evaluation of the impact of new media on perceptions of freedom of expression and privacy

New media platforms have changed the media landscape forever, as they have altered our perceptions of the limits of communication, and reception of information. Platforms such as Facebook, Twitter and WhatsApp enable individuals to circumvent the traditional mass media, converging audience and producer to create millions of ‘citizen journalists’. This new breed of journalist uses these platforms as a way of, not only receiving news, but of instantaneously, and often spontaneously, expressing opinions and venting and sharing emotions, thoughts and feelings. They are liberated from cultural and physical restraints, such as time, space and location, and they are not constrained by factors that impact upon the traditional media, such as editorial control, owner or political bias or the pressures of generating commercial revenue. A consequence of the way in which these platforms have become ingrained within our social culture is that habits, conventions and social norms, that were once informal and transitory manifestations of social life, are now infused within their use. What were casual and ephemeral actions and/or acts of expression, such as conversing with friends or colleagues or swapping/displaying pictures, or exchanging thoughts that were once kept private, or maybe shared with a select few, have now become formalised and potentially permanent, on view for the world to see. Incidentally, ‘traditional’ journalists and media outlets are also utilising new media, as it allows them to react, and disseminate news, instantaneously, within a hyper-competitive marketplace. However, in a world where we are saturated, not only by citizen journalists, but by traditional media outlets, offering access to news and opinion twenty-four hours a day, via multiple new media platforms, there is increased pressure to ‘break’ news fast and first. This paper will argue that new media, and the culture and environment it has created, for citizen journalists, traditional journalists and the media generally, has altered our perceptions of the limits and boundaries of freedom of expression dramatically, and that the corollary to this seismic shift is the impact on the notion of privacy and private life. Consequently, this paper will examine what a reasonable expectation of privacy may now mean, in a new media world.

Fifty shades of innovation – from open toward user, and open collaborative forms of innovation – an overview

Starting from the Schumpeterian producer-driven understanding of innovation, followed by user-generated solutions and understanding of collaborative forms of co-creation, scholars investigated the drivers and the nature of interactions underpinning success in various ways. Innovation literature has gone a long way, where open innovation has attracted researchers to investigate problems like compatibilities of external resources, networks of innovation, or open source collaboration. Openness itself has gained various shades in the different strands of literature. In this paper the author provides with an overview and a draft evaluation of the different models of open innovation, illustrated with some empirical findings from various fields drawn from the literature. She points to the relevance of transaction costs affecting viable forms of (open) innovation strategies of firms, and the importance to define the locus of innovation for further analyses of different firm and interaction level formations.

War Worlds: Violence, Sociality, and the Forms of Twentieth-Century Transatlantic Literature

“War Worlds” reads twentieth-century British and Anglophone literature to examine the social practices of marginal groups (pacifists, strangers, traitors, anticolonial rebels, queer soldiers) during the world wars. This dissertation shows that these diverse “enemies within” England and its colonies—those often deemed expendable for, but nonetheless threatening to, British state and imperial projects—provided writers with alternative visions of collective life in periods of escalated violence and social control. By focusing on the social and political activities of those who were not loyal citizens or productive laborers within the British Empire, “War Worlds” foregrounds the small group, a form of collectivity frequently portrayed in the literature of the war years but typically overlooked in literary critical studies. I argue that this shift of focus from grand politics to small groups not only illuminates surprising social fissures within England and its colonies but provides a new vantage from which to view twentieth-century experiments in literary form.

Analysis of expression quantitative trait loci in D. melanogaster

Expression Quantitative Trait Loci (eQTL) analysis allows for the identification of genetic variation associated with variation in gene expression. It is often unclear however, which of the associated variants are causal, and by what mechanism. Integrating functional genomic data with eQTL data can provide insight into the impact of natural variation in the population, and the nature of the transcriptional machinery itself. In this thesis, I integrate functional genomic data with eQTL data derived from both 5’ CAGE and 3’ TagXseq expression assays, in developing embryos. I first use both datasets to analyse the transcription landscape in embryonic D., melanogaster, and then carry out an analysis of sequence motifs associated with transcription factor binding sites, promoters, and 3’ polyadenylation sites. Finally, I integrate functional genomic data, including these novel sequence motifs, to shed light on the mechanisms of gene expression variation in D.,melanogaster. I am able to demonstrate that some variants effecting gene regulation in Drosophila are found within haplotypes which buffer their effects.

Settlement characteristics of quartz grains on certain sediment surface forms of tidal beaches along the Baltic and Wadden Sea

Sind in einem Sediment, das unter dem Einfluß einer Strömung abgelagert wurde, richtungsanzeigende Indikatoren vorhanden, so werden sie je nach den momentanen Bedingungen, die zur Zeit der Sedimentation herrschten, ein mehr oder weniger gutes Abbild der Strömungsverhältnisse liefern. Zahlreich sind Strömungsanzeiger organischen Ursprungs, wie z. B. Molluskenschalen u. a. Doch auch anorganische Partikel in Psephiten und Psammiten lassen häufig in ihrer Lagerung eine Abhängigkeit von der Strömungsrichtung erkennen: sie sind "geregelt". Die Autoren der verschiedenen Arbeiten, in denen Regelungen in klastischen Sedimenten untersucht wurden, gingen von der Tatsache aus, daß viele Sedimentpartikel statistisch gesehen keine Kugelform, sondern eine längliche Gestalt besitzen. Die langen Achsen dieser länglich geformten Sedimentkörner werden im folgenden als "Langachsen" bezeichnet. In Sanden sind es vor allem Quarzkörner von annähernd zylindrischer oder ellipsoidischer Form ("Langquarze"), die geeignet sind, durch die Lage ihrer Langachsen strömungsbedingte Regelungen anzuzeigen. Mit der Orientierung solcher Langquarze in marinen und fluviatilen Sanden haben sich bisher vorwiegend amerikanische Autoren befaßt. So untersuchten z. B. Dapples & Rominger (1945) die Sandsohle eines künstlichen Gerinnes. Sie stellten fest, daß die Hauptorientierungsrichtung der Langquarze mit der Strömungsrichtung des fließenden Wassers zusammenfiel. Dabei zeigte das spitze Ende tropfenförmiger ("polarer") Quarze stromab und das stumpfe Ende stromauf. Nanz (1955) maß die Langachsenrichtungen von Langquarzen in Sanden des nassen und trockenen Strandes von Texas und Florida und fand, daß sich diese Achsen vorwiegend parallel zur Auf- und Ablaufrichtung der Wellen und damit senkrecht zum Streichen der Strandlinie einregeln. Curray (1956 b) beobachtete die gleiche Regelung. Er wies ferner darauf hin, daß in Strandwällen und Strandhaken die bevorzugte Richtung der Langquarze senkrecht zum Streichen des Sedimentkörpers liegt. Zahlreiche weitere Autoren beschäftigten sich ebenfalls mit den Fragen der Langquarzregelung, so Schwarzacher (1951), Griffith & Rosenfeld (1953), Vollbrecht (1953), Rusnak (1956), Wendler (1956), Sriramadas (1957). Ganz allgemein war das Ergebnis aller dieser Untersuchungen, daß die aus einer Strömung abgelagerten Langquarze eine Regelung parallel zur Strömungsrichtung zeigen. Eigene Untersuchungen und Überlegungen ergaben, daß die bisher veröffentlichten Ergebnisse und die an sie angeschlossenen Vorstellungen z. T. bestätigt werden können, jedoch z. T. auch erheblich modifiziert werden müssen.
