In/Visibility in the Internet’s Third Age

Current research (see, for example, Cheong, Martin and Macfadyen, 2012) on patterns of global and intercultural new media penetration and use nevertheless reveal the thinness of earlier utopian hopes for a technologically mediated “global village.” Nevertheless, new media are transforming local, political and cultural landscapes. What has (and who have) been made newly in/visible by new media and technologies? Participants in this panel will present\ud and discuss aspects of their current research that shed light, in different ways, on questions of in/visibility in this, the Internet’s ‘Third Age’ (Wellman, 2011)

Form removal aspects on the waviness parameters for steel sheet in automotive applications : fourier filtering versus polynomial regression

Premium car makers attach great importance to the visual appearance of the painted car skin as an indication of product quality. The “orange peel” phenomenon constitutes a major problem here. It is not only depending on the paint’s chemical composition and application method, but also on possible waviness components in the sheet substrate. Therefore one is searching hard for a valuable waviness parameter to quantify the substrate’s fitness for purpose. A technically emerging problem is how to remove the form from the measured signal, which is indeed not significant to the orange peel phenomenon. This paper will compare two commonly used approaches: i.e. Fourier filtering versus polynomial regression and will reveal and quantify some common aspects in terms of wavelengths

Multilayer injection molding. Part 2: Particle tracking in reactive molding

The modeling of multilayer reactive injection molding is studied. After presenting the equations describing the process, 2 important aspects are dealt with in more detail. These are particle tracking and the modeling of the flow front. First results demonstrate the possibilities of the modeling and show satisfactory agreement between predictions of numerical simulations and exptl. results, concerning particle tracking in the whole flow domain and the break-through of layers in sequential 2-component moldin

Relapsing fever, a disappearing cause of fever and maternal death in Sengerema, Tanzania, east Africa

Objective: To study the incidence of tick borne relapsing fever (TBRF) during the last 50 years, once like malaria an endemic disease in Sengerema, Tanzania.Design: By analyzing the annual reports, focusing on the number of admissions, maternal deaths, blood smears of patients with fever for Borrelia.Setting: Sengerema district, Tanzania.Subject: Admissions in Sengerema Hospital due to TBRF.Main Outcome Measures: From 1960 to 2010, we analyzed the incidence of TBRF.Result: Forty annual admissions in the sixties/seventies, 200 in the eighties (range from 37 in 1964 to 455 in 1988), dropping to 30 in the nineties. For the last nine years no Borrelia spirochetes were found in blood smears at the laboratory anymore and no admissions for TBRF were  registered. The number of maternal deaths due to relapsing fever  decreased simultaneously; the last one recorded was in 2002.Conclusion: During the last century, we have witnessed the disappearing of tick borne relapsing fever in Sengerema. Increase of gold mining,  improved local economy, housing and standards of living after the nineties resulted in an almost complete eradication of the incidence of TBRF

Technisch rapport WO-Monitor 1998

In 1998 is onder auspiciën van de VSNU de WO-Monitor van start gegaan. Aanleiding hiervoor was de behoefte om over landelijke gegevens te beschikken met betrekking tot de arbeidsmarktintrede van afgestudeerden. Weliswaar werd op diverse plaatsen reeds onderzoek verricht naar de overgang van het WO naar de arbeidsmarkt, maar door de uiteenlopende designs en vraagstellingen leverde dit geen onderling vergelijkbare gegevens op. Het Algemeen Bestuur van de VSNU heeft daarom besloten tot invoering van een landelijke WO-Monitor, waarin alle universiteiten participeren.labour market entry and occupational careers;
