‘X Journalism’. Exploring journalism’s diverse meanings through the names we give it

In this article we propose the notion of X Journalism as an observational tool and concept. It owes its existence to a simple observation: the evolution of journalism is accompanied by the emergence of ever-new journalism-related terms, i.e. combinations of the word ‘journalism’ with a particular modifying term that represents and signals a certain specificity and novelty. Examples include ‘robot journalism’, ‘foundation- funded journalism’, ‘cross-border journalism’, or ‘solutions journalism’ – just to name a few. To date, we have collected and mapped 166 X journalisms and have ‘crowd- categorized’ them into clusters according to the different aspects they refer to. We explore X Journalism as a concept, present our mapping, and show how it can help to cope with journalism’s increasing complexity, grasp the diversity of the field, trace its constant evolution, as well as identify patterns and interrelations between these different movements and occurrences. Through a test case of audience-related X journalisms we demonstrate an empirical application before illustrating the theoretical compatibility of X Journalism and suggesting a research agenda that highlights potentials for X Journalism-driven studies.<br/

Additive Polynomials for Finite Groups of Lie Type

This paper provides a realization of all classical and most exceptional finite groups of Lie type as Galois groups over function fields over F_q and derives explicit additive polynomials for the extensions. Our unified approach is based on results of Matzat which give bounds for Galois groups of Frobenius modules and uses the structure and representation theory of the corresponding connected linear algebraic groups.Comment: 59 pages; v2: added reference, slightly restructured section 6.1, few small rewordings; v3: completed realization of Steinberg's triality groups (thanks to P. Mueller for solving the remaining open question); clarified argument how to use Thm. 3.

TREX exposes the RNA-binding domain of Nxf1 to enable mRNA export

The metazoan TREX complex is recruited to mRNA during nuclear RNA processing and functions in exporting mRNA to the cytoplasm. Nxf1 is an mRNA export receptor, which binds processed mRNA and transports it through the nuclear pore complex. At present, the relationship between TREX and Nxf1 is not understood. Here we show that Nxf1 uses an intramolecular interaction to inhibit its own RNA-binding activity. When the TREX subunits Aly and Thoc5 make contact with Nxf1, Nxf1 is driven into an open conformation, exposing its RNA-binding domain, allowing RNA binding. Moreover, the combined knockdown of Aly and Thoc5 markedly reduces the amount of Nxf1 bound to mRNA in vivo and also causes a severe mRNA export block. Together, our data indicate that TREX provides a license for mRNA export by driving Nxf1 into a conformation capable of binding mRNA

Social media conflicts during the financial crisis: Managerial implications for retail banks

Social media can be used proactively to disseminate accurate corporate information and address undesirable consumer behaviors online in order to help counteract negativity in the business environment in the wake of a financial crisis. Social media thus has become a popular open forum for financial institutions such as retail banks to engage in corporate dialogue with consumers. We recommend that financial services firms preemptively use their social media?based online communities in order to disseminate accurate corporate information in times of a financial crisis. Particularly, firms can choose between a range of reactive and proactive strategies to manage social conflict in the wake of a financial crisis
