Do So

Over the past three decades our media ecologies have changed substantially, not at least changing the ways in which we get in touch with the news. These changes have led both to high hopes for more equality in news access and a better-informed electorate, as well as fears of news avoidance, filter bubbles, and increasing knowledge gaps, with recent empirical evidence leaning towards rather pessimistic perspectives. However, most of the research to date focusses on one specific kind of news access, e.g., news consumption via social media, and its effects, neglecting the fact that users combine several ways to access the news throughout their daily lives, creating their individual media use repertoires. In order to disentangle these variances within our daily lives from differences between users, we need to analyze access to news on a situational level. Being meta-media, mobile media constitute an excellent microcosmos to study situational variability in news access. Hence, we investigated the situational types of mobile news access in young adults’ daily lives as well as their mobile news repertoires based on the previously identified situational access types. To do so, we conducted an experience sampling study among young adults in Germany. Our results highlight that differences within (mobile) news use should not only be studied as differences between people, but also as variances within users’ daily lives. For example, we see that no mobile news repertoire in our study solely relies on news access via intermediaries such as social media.

This paper reviews the use of our intra-oral crown single-section model for the evaluation of in situ demineralization and remineralization. The model uses normal, healthy adults who are in need of a gold crown. A slot is placed in the working crown which can hold 3–4 single sections. A typical experiment would use an enamel lesion, root lesion, and sound root section which are characterized with polarized light microscopy and/or microradiography prior to insertion in the crown. After the experimental regimen, the sections are removed and re-characterized for any changes. The model has been used to evaluate mineral changes from the use of fluoride dentifrices and rinses, chewing gum, and food sequencing. The advantages of the model system are the before-and-after measurements on the same section, a natural plaque formation, interaction with saliva, episodic demineralization and remineralization, no bulky appliances, and the use of reasonable time frames. This model, therefore, reduces the artificiality of the in situ study to a great extent and appears to be a useful predictor of demineralization/remineralization interactions.

Aims: To evaluate the real-life effect of photocatalytic surfaces on the air quality at two test-sites in Denmark. Background: Poor air quality is today one of the largest environmental issues, due to the adverse effects on human health associated with high levels of air pollution, including respiratory issues, cardiovascular disease (CVD), and lung cancer. NOx removal by TiO2 based photocatalysis is a tool to improve air quality locally in areas where people are exposed. Methods: Two test sites were constructed in Roskilde and Copenhage airport. In Roskilde, the existing asphalt at two parking lots was treated with TiO2 containing liquid and an in-situ ISO 22197-1 test setup was developed to enable in-situ evaluation of the activity of the asphalt. In CPH airport, photocatalytic concrete tiles were installed at the "kiss and fly" parking lot, and NOx levels were continuously monitored in 0.5 m by CLD at the active site and a comparable reference site before and after installation for a period of 2 years. Results: The Roskilde showed high stability of the photocatalytic coating with the activity being largely unchanged over a period of 2 years. The CPH airport study showed that the average NOx levels were decreased by 12 % comparing the before and after NOx concentrations at the active and reference site. Conclusion: The joined results of the two Danish demonstration projects illustrate a high stability of the photocatalytic coating as well as a high potential for improvements of the real-life air quality in polluted areas.
