We highlight some nuanced differences or shortfalls across Denmark, Finland, Norway, and Sweden, and give some policy recommendations to national governments and industry in order to maintain a professional Nordic standard. The article identifies a degree of social, cultural, and economic coherence in the Nordic context that allows for the Danish, Finnish, Norwegian, and Swedish influencer industries to be viewed as a collaborative entity. It then reviews the status of income and tax procedures, and the regulation of commercial disclosures for influencers in the Nordic region. It is hoped that this research contributes to strengthening the integrity and rigour of the Nordic influencer industry to serve as a model for other regional networks of influencers.

Annual deaths due to pneumonia in these groups was estimated at more than one million and 672 000 worldwide for both groups, respectively, in 2019 [1]. The importance of pneumonia is highlighted by impact of the current coronavirus disease 2019 (COVID-19) pandemic on vulnerable populations. Yet, despite the high impact of pneumonia worldwide, diagnosing pneumonia, especially in children in low- and middle-income countries, remains a big challenge. Frequent clinical signs of pneumonia (cough and difficult or rapid breathing) are non-specific and can overlap with other prevalent diseases in these settings, such as malaria. Equally important, data provided by the World Health Organization (WHO) revealed that 40% of children with pneumonia symptoms in the 40 countries reporting 90% of child pneumonia deaths never receive medical care for their pneumonia [2]. Furthe...

We introduce theories of social influence, consumerism, and new feminism to enlighten our discussion of how the social influencers exercise their influence. We present the results and analysis of the visual and textual content of 5,083 Instagram postings as well as supplementary online content. In our conclusion, we discuss the significance of the social influencers' negotiation of consumerism and feminism on Instagram as well as directions for future research.

The research problem is that single actors’ specific interests often define development of public places, whilst a public sense of ownership often characterizes urban quality. We discuss how social data and the development of artefacts can address this issue by introducing the concepts of discursive design and speculative design in the architectural design process. We contribute to the design research (IS) as well as the discursive design traditions through the disclosure of the development process of Vika Terrace. In framing our study as discursive design, our primary goal was to design for a deeper understanding and awareness of the role of publics in design processes.

Only 3 percent of the budget went to preventive health, despite the fact that preventive measures hold the greatest promise. At the same time, computerbased technology enables measuring and gathering large amounts of health-related data, like a person’s activity level, heart rate, sleep patterns, eating habits, exercise habits and even emotional state. The popularity of personal electronic recording equipment, along with the extensive use of social media, result in large collections of data that are continuously expanding. Currently this wealth of information is not accessible to healthcare professions, instead it is contained within a data shadow. Even with access, the majority of health personnel would be unable to break the data down to sensible and usable information. This research project is founded in the per...

Such a dataset enables development of several interesting analysis applications, e.g., where additional sports data can be used to predict and analyze everyday developments like a person's weight and sleep patterns, and where traditional lifelog data can be used in a sports context to predict an athletes performance. In this respect, we have used the Fitbit Versa 2 smartwatch wristband, the PMSYS sports logging app, and Google forms for the data collection. PMData contains logging data of 12 persons from a period of 3 months. Our initial experiments show that such analyses are possible, but there are still large rooms for improvements.

Asthma is a chronic disease affecting more than 300 million people globally. Poor asthma control ... more Asthma is a chronic disease affecting more than 300 million people globally. Poor asthma control that leads to unnecessary symptoms is estimated to affect nearly half of people with asthma. A critical way to address poor control is for healthcare professionals (HCPs) and patients to enter a shared dialogue on treatment and asthma management. This article explores the views of both patient and HCP to better understand how to achieve asthma control. From the patient's perspective, being a person with asthma has ramifications to one's sense of identity, and thus one's ability and willingness to actively manage their asthma. Furthermore, lack of education and concerns about the effectiveness of treatment can also ultimately lead to poor control, a term that can be understood differently by patients and HCPs. One goal is to help to normalise life for people with asthma. For this, HCPs need to align on what this means for each individual and then work together to produce a plan that can be applied to the patient's daily life. Training for HCPs on good communication skills and empowering patients to be involved in their asthma management are both critical to ensure effective shared decision-making and, ultimately, improved quality of life for people with asthma.

In this paper, we analysed data from Facebook walls of 153 public organisations using unsupervised machine learning techniques to understand the characteristics of user engagement and post performance. Our analysis indicates an increasing trend of user engagement on public health posts during recent years. Based on the clustering results, our analysis shows that Photo and Link type posts are most favourable for high and medium user engagement respectively.

Location-aware technologies allow people to access, annotate, address and attach information to locations, which transforms the space for other people who use the same services. Such locations acquire relevance and reshape social and spatial interactions through increased use on social media as people ‘check-in' to places, photograph or ‘like' them. Collectively the authors are marking-up the city around them. The popularization of location-aware technologies thus contributes to the changing meaning of locations in cities. In contrast to the technological focus in the emerging discourses on smart cities and big data, this paper offers an alternative view of the three lenses of Social, Local and Mobile technologies that describe and explain crowd-sourced socio-technical layers on the...

Contrary to expectation, a following wind in the “standard direction” was found to be of no significant positive influence — the sign of the correlation was even negative.

K, Ca, Mg, Cu, and Pb showed approximately the same average contents in fresh and in dried soil, whereas in the case of Mn, P, Fe, and Zn an average of up to the double contents was measured in dried soil. There proved to be a correlation between content of organic matter and respectively pH, conductivity, contents of Cu, Zn, and Pb, as well as between conductivity and contents of respectively water soluble Ca and Mg and of Fe. The vegetation analyses have been grouped in six sociations on the basis of similarity in the frequency of species. Characteristic differences in edaphic conditions between the sociations are pointed out, and there proves to be some mutual correlation between contents of Na, K, Ca, Mg, and P as well as between contents of Fe, Cu,

The probe consists of a Germanium-transistor of small dimensions. The 0-current, being a logarithmic function of temperature, is amplified in a Siliciumtransistor and integrated in a Cu-voltameter. The method employed in calibration and in calculating integral and mean temperature is explained. Ten instruments were placed in the bottom layer in different types of vegetation in South West Greenland in the period from 5./6.7.-20.8. 1965. Beside of 6 of the instruments liquid thermometers were placed for measuring daily maximum and minimum temperatures. An assessment of the uncertainties of measurements of mean temperatures by the instruments shows that the temperature usually can be recorded with an error of ?0.2-0.40C. The investigations showed that the highest mean temperature in the period, 37.20C, and the highest maximum temperature, 57.00C, were measured at the same locality, viz. in an open scrub on a dry slope with southern exposure, while the lowest mean temperature, 17.00C, and the lowest maximum temperature, 32.00C, were measured at a locality in a moor near a small brook. It is concluded that the instrument developed is suitable for measuring microclimatic mean temperatures over long periods in nature. The investigations have shown that even in arctic vegetation rather high micro-climatic temperatures may occur in the period of growth. Pe3IoMe

The influence of thermal conductivity of the case material on the heat flux inside the module is discussed by 3-D simulations. The use of graphite allows an operation with spatial inhomogenities of ⩽1°C in the case parts and leads to a sufficient low sensor temperature level. Experiments with a single-stage thermoelectric cooler and heat sink mounted on top of the module confirm that the temperature of the sensor and electronics as well as the case temperature depend linearly on their power dissipation. A set of equations considering the thermal coupling between sensor and electronics fully describe the dependence of their operating temperatures on sensor and electronics power dissipation, cooling power, and ambient temperature under forced convection. The simulated curves show a very good quantitative agreement with the measured characteristics. At a power dissipation level of 1.25 W , an ambient temperature of 22°C and air velocity of ⩾18 cm / s the sensor can be operated down to 13°C and 9°C with a cooling power of 2.8 and 7 W , respectively. Without cooling fan and cooling power the sensor temperature remains below 35°C.

The following developments were apparent: 1. The outer shore zone changed from a Cakile-dominated vegetation to a sparse and less diverse vegetation. 2. The inner shore zone maintained spontaneous Ammophila as dominant and developed into a mobile dune with changing species. 3. The outer dune slope with planted Ammophila developed into a mobile dune dominated by vigorous Ammophila. 4. The dune zone with planted Ammophila: The outer part developed towards a somewhat fixed dune with increasing diversity. The inner part developed into a diverse and more fixed dune community with mainly Festuca rubra. 5. The inner dune slope developed into a vegetation comprising few species. 6. The grassland zone, initially sown with Festuca rubra and Lolium perenne, changed into a grass-herb-vegetation dominated by Festuca rubra, with a slowly increasing number of immigrating species, changing from annuals to perennials, in particular species of Fabaceae and Hippophae.
