Challenges and confusion in media and communication regulation: a four country comparison.
In this chapter we discuss recent developments and challenges in European media and communication policy, focussing on the period since the 2008 global financial crisis. We are especially interested in the implications of the financial crisis and its political repercussions nationally (austerity measures and cuts to public services as well as growing anti-politics sentiments and widespread dissatisfaction with free-market capitalism and representative democracy) for media and communication policy, understood here in a broad sense, so to include all electronic communications, such as the Internet, mobile communications, social media etc. Our overarching concern is with the implications of developments in media and communication policy for the democratic functions of the media in Europe
Learning by Augmented Reality : Cluster Analysis Approach
Because the use of augmented reality (AR) is increasing, it is important to study its possibilities within both formal and informal learning contexts. We clustered 146 sixth graders using AR at a science center based on their reasoning, motivation, and science learning results using the self-organizing maps method (SOM) to identify AR-using subgroups. The aim was to consider reasons why the AR method could be of more beneficial for some students than others. The clustering results complemented earlier findings on AR gains in learning, as an unexpected response to intervention was discovered using this nonlinear analysis. The previous results had indicated that after the AR experience, science test results generally improved and particularly among students with the lowest achievement. The SOM-clustering results showed a majority group of boys, especially those interested in science learning both at school and at the science center using AR. Despite low school achievement, their high motivation led to good science learning results. The prior results, according to which girls closed the science knowledge gap between boys after using AR, became more relative, as two girldominated subgroups were identified. The reasons for the results were considered on the basis of motivation, multimedia learning theory, and concept formation theories.

A retrospective evaluation of patients switched from buprenorphine (subutex) to the buprenorphine/naloxone combination (suboxone)
<p>Abstract</p> <p>Background</p> <p>In Finland, buprenorphine (Subutex) is the most abused opioid. In order to curb this problem, many treatment centres transferred ("forced transfer") their buprenorphine patients to the buprenorphine plus naloxone (Suboxone) combination product in late 2003.</p> <p>Methods</p> <p>Data from a retrospective study involving five different treatment centers, examining the effects of switching patients to Suboxone, were gathered from 64 opioid-dependent patients who had undergone the medication transfer.</p> <p>Results</p> <p>Most patients (90.6%) switched to Suboxone at the same dose of buprenorphine that they had been receiving as Subutex (average 22 mg). The majority of these patients (71.9%) were maintained at the same dose of Suboxone throughout the 4-week study period. During the first 4 weeks, 50% of the patients reported adverse events and at the four month time point, 26.6% reported adverse events. However, due to adverse events one patient only discontinued treatment with Suboxone during the 4-week study period, and five during the four month follow-up period. Of the 26 patients in the follow-up period, Suboxone was misused intravenously once each by 4 patients and twice by 1 patient. These 5 patients all reported that injecting Suboxone was like injecting "nothing" with any euphoria, or that it was a bad experience.</p> <p>Conclusion</p> <p>We conclude that when patients are transferred from high doses (> 22 mg) of buprenorphine to the combination product, dose adjustments may be necessary especially in the later phase of the treatment. We recommend that a transfer from Subutex to Suboxone should be carefully discussed and planned in advance with the patients and after the transfer adverse events should be regularly monitored. With regard of buprenorphine IV abuse, the combination product seems to have a less abuse potential than buprenorphine alone.</p
STEAM-Learning to Mars: Students’ Ideas of Space Research
Multidisciplinarity and the enrichment of science and mathematics education toward the so-called STEAM-approach where the A stands for art, has raised a lot of academic interest in the past decade. In this study, 5th and 6th graders from the greater Helsinki area (N = 390) participated in a several months long, Mars-colonization themed STEAM-learning intervention. Testing the students’ science knowledge using pre- and post-tests, their learning outcomes were compared to those of 5th and 6th graders from a control school (N = 119), who during the same period studied STEM-subjects in a more traditional manner. The main factors that were taken into account during the comparisons were gender and academic achievement level. Based on only whether there was any improvement between the pre- and post-test scores, girls were found to have benefitted from the Mars-module more than boys did. While also considering the magnitude of the said improvement, no significant difference in the effectiveness of the learning module was found between genders. The group of academically highest-achieving students improved their test scores the most after participating in the STEAM-learning module. This is an important, somewhat surprising finding, as often informal, outside of school learning has been found to benefit especially students with lower grade point averages
Dietary fibre in legumes, seeds, vegetables, fruits and mushrooms : Comparing traditional and semi-automated filtration techniques
The method AOAC 2011.25 was used to analyze all the dietary fibre (DF) components included in the latest definition by the Codex Alimentarius Commission (2009). The traditional filtration technique, described in the method AOAC 2011.25, was compared with a new semi-automated filtration technique using Fibertec" 1023 system. For the comparisons, a statistical similarity approach was chosen to evaluate the results of six food matrixes (wheat flour, edible boletus, strawberry, tomato, green pea and horse radish). The total DF contents of the tested matrixes fit within 16% tightest data-induced similarity limit of the manual mean, with one exception (strawberry; 30%). Thus, it was concluded that both techniques are suitable for use with the method AOAC 2011.25, and therefore either technique was used to analyze a wide selection of legumes, seeds, vegetables, fruits and mushrooms (44 foods). Seeds were excellent sources of total DF, as well as water-insoluble (IDF) and water-soluble (SDFP) polysaccharides. A substantial amount of oligosaccharides (SDFS) was found in red onions. Generally, the DF contents were higher in this study than in earlier studies. Higher DF results can be partially explained by the more effective analytical method, and partly by changed varieties.Peer reviewe
Hands-On Math and Art Exhibition Promoting Science Attitudes and Educational Plans
Creative Commons Attribution License (CC BY 4.0)The current science, technology, engineering, art, math education (STEAM) approach emphasizes integration of abstract science and mathematical ideas for concrete solutions by art. The main aim was to find out how experience of learning mathematics differed between the contexts of school and an informal Math and Art Exhibition. The study participants () were 12-13 years old from Finland. Several valid questionnaires and tests were applied (e.g., SRQ-A, RAVEN) in pre- and post-design showing a good reliability. The results based on General Linear Modeling and Structural Equation Path Modeling underline the motivational effects. The experience of the effectiveness of hands-on learning at school and at the exhibition was not consistent across the subgroups. The lowest achieving group appreciated the exhibition alternative for math learning compared to learning math at school. The boys considered the exhibition to be more useful than the girls as it fostered their science and technology attitudes. However, for the girls, the attractiveness of the exhibition, the experienced situation motivation, was much more strongly connected to the attitudes on science and technology and the worthiness of mathematics. Interestingly, the pupils experienced that even this short informal learning intervention affected their science and technology attitudes and educational plans.Peer reviewe
Effect of colostrum feeding method and presence of dam on the sleep, rest and sucking behaviour of newborn calves
"In rats, sucking milk reduces anxiety and promotes non-rapid eye movement (NREM) sleep, and in calves it induces resting but the effect on sleep is unknown. Here, we investigated how calves' sleep was affected by colostrum feeding methods. Forty-one calves were blocked by birth date and randomly allotted within blocks to the experimental treatments. Calves were housed for four days either with their dam (DAM) or individually with warm colostrum feeding (2 L four times a day) from either a teat bucket (TEAT) or an open bucket (BUCKET). DAM calves suckled their dam freely. Calves' sleeping and sucking behaviour was filmed continuously for 48 h at the ages of two and three days. Behavioural sleep (BS) was defined as calves resting at least 30 s with their head still and raised (non-rapid eye movement) or with their head against their body or the ground (rapid eye movement, REM). Latency from the end of colostrum feeding to the start of BS was recorded. We compared behaviour of TEAT calves with that of DAM and BUCKET calves using mixed models. Milk meal duration was significantly longer for TEAT calves than for BUCKET calves (mean +/- S.E.M.; 8.3 +/- 0.6 min vs. 5.2 +/- 0.6 min), but equal to that of DAM calves. We found no effect of feeding method on the duration of daily BS (12 h 59 min I h 38 min) but we found a tendency for the daily amount of NREM sleep; BUCKET calves had less NREM sleep per day than TEAT calves (6 h 18 min vs. 7 h 48 min, S.E.M. = 45 min) and also longer latencies from milk ingestion to BS (21.9 +/- 2.0 min vs. 16.2 +/- 2.0 min). DAM calves slept longer bouts than TEAT calves (10.8 +/- 1.0 min vs. 8.3 +/- 1.0 min) and less often (78 +/- 4 vs. 92 +/- 4).
