RESUMEN

Environmental degradation and how we care for our planet are some of the greatest challenges the world is up against at this moment. These challenges has received increased focus in both, research and the public sphere. So far, most of this attention revolved around adult's attitudes and behavior. However, environmental engagement amongst the younger generation gains in popularity. Using plastic pollution as a case, this qualitative study aims to acquire insights into the mental models of children. We collected qualitative data during an innovative, structured workshop according to the "Nature In Your Face" (NIYF) framework. The approach challenges the assumption that the societal change can be achieved gradually, with non-invasive techniques. Instead, we explore the potential of disruption to push citizens out of their comfort zone, thereby making room for co-creation. The disruption was performed by confronting 36 fifth graders from a Norwegian primary school, with disturbing images of plastic contaminating their local shorelines. The data was obtained by using the workshop framework, combined with semi-structured group interviews. The interview data was analyzed by means of thematic analysis. We found that the disruptions triggered emotional reactions like anger and fear. With these emotions as a driving force, the first workshop step was introduced, the Framing of the problem. The next step, Twisting the problem, was reflected in the children developing their own, creative solutions and creatively engaged with them in groups. The last step, Using, was only touched upon in the workshop and is therefore beyond the scope of this paper. Our results indicate that there are three prominent themes reflecting how children discuss plastic pollution. The children talked about their (1) Emotions related to plastic pollution, (2) Attitudes related to plastic, and (3) Perceptions of plastic pollution. These themes were further subdivided into different types of emotions, characteristics of plastic as a material as well as perceptions on different locations of unnecessary plastic. Psychologically, the mechanisms underlying the identified themes were linked to eco-anxiety, denial, self-efficacy, and cognitive dissonance. We conclude that disruptive eco-visualization can create an emotional response amongst children, which can be transformed into co-creation of ideas.

RESUMEN

Smart home systems create new opportunities for patient care. In this paper, a role model is created for the different groups of people involved in the care process of an occupant. Based on a systematic literature review seven roles were identified. A second literature review deals with the topic Feedback of Smart Home Systems. Combining both reviews visualization proposals were created and are presented for two of the roles. The role model is adapted to German health system but could be transformed for different countries. To confirm the results an evaluation of role model and visualization proposal should be done in collaboration with possible users of smart homes.

RESUMEN

Rehabilitation of musculoskeletal diseases (MSD) of the shoulder is a multifaceted long-term process, which is often not transparent to affected patients. Mobile health applications (apps) have the potential to support this complex process by improving patients' self-management skills. However, there seems to be a lack of apps providing a holistic approach to motivate and guide patients during the whole rehabilitation process. Therefore, a systematic analysis of apps on Google Play Store was conducted by two independent reviewers. A total of 3227 apps were identified, of which 64 met the eligibility criteria for the qualitative analysis. The majority of analyzed apps were developed generally for patients with MSD of the shoulder, rarely for specific diseases (individual needs of patients). The majority of apps focus on the provision of information, exercise training, and alternative medicine. Apps for diagnostics, inpatient treatment, and self-management, especially for multiple rehabilitation phases, are rare or even not existent. Game design elements are seldom used. If there are any, then simple to implement ones, e.g. messages and progress bars. The (psychological) effects of individual game design elements on patients seem to be neglected, when selecting and implementing game-components.

RESUMEN

The mechanical properties of cancer cells and their microenvironment contribute to breast cancer progression. While mechanosensing has been extensively studied using 2D substrates, much less is known about it in a physiologically more relevant 3D context. Here it is demonstrated that breast cancer tumor spheroids, growing in 3D polyethylene glycol-heparin hydrogels, are sensitive to their environment stiffness. During tumor spheroid growth, compressive stresses of up to 2 kPa build up, as quantitated using elastic polymer beads as stress sensors. Atomic force microscopy reveals that tumor spheroid stiffness increases with hydrogel stiffness. Also, constituent cell stiffness increases in a Rho associated kinase (ROCK)- and F-actin-dependent manner. Increased hydrogel stiffness correlated with attenuated tumor spheroid growth, a higher proportion of cells in G0/G1 phase, and elevated levels of the cyclin-dependent kinase inhibitor p21. Drug-mediated ROCK inhibition not only reverses cell stiffening upon culture in stiff hydrogels but also increases tumor spheroid growth. Taken together, a mechanism by which the growth of a tumor spheroid can be regulated via cytoskeleton rearrangements in response to its mechanoenvironment is revealed here. Thus, the findings contribute to a better understanding of how cancer cells react to compressive stress when growing under confinement in stiff environments.

RESUMEN

This paper discusses conceptual confusions of sustainable seafood consumption, practical challenges, and potential anchors from where this behaviour can be fostered. The main focus lies on psychological variables. The resulting framework comprises (1) a definition of sustainable seafood consumption, (2) suggestions for corresponding behaviours, (3) the identification of facilitating and hindering factors, (4) an assemblage of these factors into a theoretical model, and (5) a short discussion of how the model adds up value to the current state of the art in marine resource conservation. Behavioural models significantly contribute to behavioural change research. The originality and value of this research are that it tackles the so far relatively neglected field of sustainable seafood consumption as important part of sustainable development and marine conservation in the future. From an interventional perspective, the developed model facilitates the identification of contact points to approach consumers and disseminate sustainable seafood consumption among modern Western consumers.

RESUMEN

Nutritional factors such as casein hydrolysates and long chain polyunsaturated fatty acids have been proposed to exert beneficial metabolic effects. We aimed to investigate how a casein hydrolysate (eCH) and long chain polyunsaturated fatty acids could affect human primary adipocyte function in vitro. Incubation conditions with the different nutritional factors were validated by assessing cell vitality with lactate dehydrogenase (LDH) release and neutral red incorporation. Intracellular triglyceride content was assessed with Oil Red O staining. The effect of eCH, a non-peptidic amino acid mixture (AA), and long-chain polyunsaturated fatty acids (LC-PUFAs) on adiponectin and leptin secretion was determined by enzyme-linked immunosorbent assay (ELISA). Intracellular adiponectin expression and nuclear factor-κB (NF-κB) activation were analyzed by Western blot, while monocyte chemoattractant protein-1 (MCP-1) release was explored by ELISA. The eCH concentration dependently increased adiponectin secretion in human primary adipocytes through its intrinsic peptide bioactivity, since the non-peptidic mixture, AA, could not mimic eCH's effects on adiponectin secretion. Eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and DHA combined with arachidonic acid (ARA) upregulated adiponectin secretion. However, only DHA and DHA/ARA exerted a potentanti-inflammatory effect reflected by prevention of tumor necrosis factor-α (TNF-α) induced NF-κB activation and MCP-1 secretion in human adipocytes. eCH and DHA alone or in combination with ARA, may hold the key for nutritional programming through their anti-inflammatory action to prevent diseases with low-grade chronic inflammation such as obesity or diabetes.

RESUMEN

A belief in human dominance over nature lies at the heart of current environmental problems. In this article, we extend the theoretical scope of social dominance theory by arguing that social dominance orientation (SDO) is an important variable in understanding person-environment relations. We argue that individuals high in SDO are more willing to exploit the environment in unsustainable ways because SDO promotes human hierarchical dominance over nature. Four studies provide support for this perspective. High SDO was associated with lower levels of environmental concern in a nationally representative New Zealand sample (Study 1) and in country-level data across 27 nations (Study 2). SDO was also positively related to utilization attitudes toward nature (Study 3) and mediated the gender difference in beliefs about anthropogenic climate change (Study 4), and both occurred independently of right-wing authoritarianism. Implications for the human-dominated view of nature subscribed to by those high in SDO are discussed.

RESUMEN

The labeling of biomolecules has become standard practice in molecular biosciences. Modifications are used for detection, sorting and isolation of small molecules, complexes and entire cells. We have recently reported a method for introducing internal chemical and structural modifications into kbp-sized DNA target substrates that are frequently used in single-molecule experiments. It makes use of nicking enzymes that create single-stranded DNA gaps, which can be subsequently filled with labeled oligonucleotides. Here we provide a detailed protocol and further expand this method. We show that modifications can be introduced at distant loci within one molecule in a simple one-pot reaction. In addition, we achieve labeling on both strands at a specific locus, as demonstrated by Förster resonance energy transfer (FRET) experiments. The protocol requires an initial cloning of the target substrate (3-5 d), whereas the labeling itself takes 4-6 h. More elaborate purification and verification of label incorporation requires 2 h for each method.
