Turning Gigabytes into Gigs: “Songification” and Live Music Data

Complex data is challenging to understand when it is represented as written communication even when it is structured in a table. How- ever, choosing to represent data in creative ways can aid our under- standing of complex ideas and patterns. In this regard, the creative industries have a great deal to offer data-intensive scholarly disci- plines. Music, for example, is not often used to interpret data, yet the rhythmic nature of music lends itself to the representation and anal- ysis of temporal data.Taking the music industry as a case study, this paper explores how data about historical live music gigs can be analysed, extend- ed and re-presented to create new insights. Using a unique process called ‘songification’ we demonstrate how enhanced auditory data design can provide a medium for aural intuition. The case study also illustrates the benefits of an expanded and inclusive view of research; in which computation and communication, method and media, in combination enable us to explore the larger question of how we can employ technologies to produce, represent, analyse, deliver and exchange knowledge

Facilitering van de gewelddadige jihad

Summary in English Muslims who do not actively contribute to the violent jihad but who tacitly or openly sympathize with it are vital to the persistence of this kind of terrorism according to some terrorist fighters and scholars. We used interviews and public information in order to examine the accuracy of this claim. The analysis points out that sympathizers are indeed crucial to some preparative terrorist activities, yet not to other. Muslim extremists depend less on sympathizers for making foreign journeys, generating revenues, and communication then they do for recruiting and sponsoring. This conclusion implies that receding of sympathy for the violent jihad will not automatically reduce it

Intrinsic vowel pitch: a gradient feature of vowel systems

This paper investigates the average fundamental frequency of eight peripheral vowels in Belgian Standard Dutch in order to examine whether a vowel gradient exists with respect to Intrinsic Vowel Pitch (IF0). The results show that IF0 exists in Belgian Standard Dutch and amounts to 3.26 semi-tones. It is found that the assumed gradience in the degree of openness/tongue height is only reflected to a certain extent in vowel F0: mid vowels have intermediate values between those of high and low vowels and there is no significant difference between the close-mid and open-mid vowels. This suggests that gradience in the degree of opening in vowel articulation does not correspond directly to a gradient change in F0, but that the mechanical coupling between articulation and the laryngeal system has a non-uniform effect on intrinsic vowel F0

Completeness of the cubic and quartic H\'enon-Heiles Hamiltonians

The quartic H\'enon-Heiles Hamiltonian $H = (P_1^2+P_2^2)/2+(\Omega_1 Q_1^2+\Omega_2 Q_2^2)/2 +C Q_1^4+ B Q_1^2 Q_2^2 + A Q_2^4 +(1/2)(\alpha/Q_1^2+\beta/Q_2^2) - \gamma Q_1$ passes the Painlev\'e test for only four sets of values of the constants. Only one of these, identical to the traveling wave reduction of the Manakov system, has been explicitly integrated (Wojciechowski, 1985), while the three others are not yet integrated in the generic case $(\alpha,\beta,\gamma)\not=(0,0,0)$. We integrate them by building a birational transformation to two fourth order first degree equations in the classification (Cosgrove, 2000) of such polynomial equations which possess the Painlev\'e property. This transformation involves the stationary reduction of various partial differential equations (PDEs). The result is the same as for the three cubic H\'enon-Heiles Hamiltonians, namely, in all four quartic cases, a general solution which is meromorphic and hyperelliptic with genus two. As a consequence, no additional autonomous term can be added to either the cubic or the quartic Hamiltonians without destroying the Painlev\'e integrability (completeness property).Comment: 10 pages, To appear, Theor.Math.Phys.

Trust in public relations in the age of mistrusted media: A European perspective

One of the core problems of misinformation and post-trust societies is, indeed, trust in communications. The undermining of the credibility of media as the backbone of democratic societies is becoming a serious problem that affects democracy, business and all kinds of public institutions and organizations in society(ies). This paper explores perceptions of trust in key stakeholders involved in communication on behalf of organizations. Findings are considered at the professional (macro), departmental (meso) and individual (micro) level as well as considering the trusted role of non-specialist communicators for organizations including internal and external spokespeople. Data were collected from an online survey of 2883 respondents from 46 countries across Europe. Key findings were at the macro level that: antagonism between management communication professionals and journalists remains. The lowest trust in the profession is felt to be by the general public. At the meso level, top executives are perceived to trust the department the most followed by journalists in second place. External experts such as professors and consultants are perceived to be the most trusted by the general public. Finally, at the micro level individuals are more trusted than organizations or departments and the communication profession more widely
