    Get PDF
    The aim of this paper is to discuss the unexploited forces of user-orientation and shared responsibility to promote sustainable value co-creation during service innovation projects in welfare service ecosystems. The framework is based on the theoretical field of public service logic (PSL) and our thesis is that service innovation seriously requires a user-oriented approach, and that such an approach enables resource integration based on the service-user’s needs and lifeworld. In our findings, we identify prerequisites and opportunities of collaborative service innovation projects in order to transform these projects into sustainable resource integration once they have ended

    Risk Exposure to Particles – including Legionella pneumophila – emitted during Showering with Water-Saving Showers

    The increase in legionellosis incidence in the general population in recent years calls for a better characterization of the sources of infection, such as showering. Water-efficient shower systems that use water atomization technology may emit slightly more inhalable bacteria-sized particles than traditional systems, which may increase the risk of users inhaling contaminants associated with these water droplets. To evaluate the risk, the number and mass of inhalable water droplets emitted by twelve showerheads—eight using water-atomization technology and four using continuous-flow technology— were monitored in a shower stall. The water-atomizing showers tested not only had lower flow rates, but also larger spray angles, less nozzles, and larger nozzle diameters than those of the continuous-flow showerheads. A difference in the behavior of inhalable water droplets between the two technologies was observed, both unobstructed or in the presence of a mannequin. The evaporation of inhalable water droplets emitted by the water-atomization showers favored a homogenous distribution in the shower stall. In the presence of the mannequin, the number and mass of inhalable droplets increased for the continuous-flow showerheads and decreased for the water-atomization showerheads. The water-atomization showerheads emitted less inhalable water mass than the continuous-flow showerheads did per unit of time; however, they generally emitted a slightly higher number of inhalable droplets—only one model performed as well as the continuous-flow showerheads in this regard. To specifically assess the aerosolisation rate of bacteria, in particular of the opportunistic water pathogen Legionella pneumophila, during showering controlled experiments were run with one atomization showerhead and one continuous-flow, first inside a glove box, second inside a shower stall. The bioaerosols were sampled with a Coriolis¼ air sampler and the total number of viable (cultivable and noncultivable) bacteria was determined by flow cytometry and culture. We found that the rate of viable and cultivable Legionella aerosolized from the water jet was similar between the two showerheads: the viable fraction represents 0.02% of the overall bacteria present in water, while the cultivable fraction corresponds to only 0.0005%. The two showerhead models emitted a similar ratio of airborne Legionella viable and cultivable per volume of water used. Similar results were obtained with naturally contaminated hoses tested in shower stall. Therefore, the risk of exposure to Legionella is not expected to increase significantly with the new generation of water-efficient showerheads

    Training Methods to Improve Sports Performance and Health

    Get PDF
    There are several types of training methods aiming to develop sports performance and improve health indicators. Fundamentally, training methods are the result of manipulating different training variables, and the possibility of combining these variables is vast. Therefore, the search to study the effect of these constraints on sports and health, considering specific contexts and taking into account the magnitude of inter-individual responses, will afford a better understanding of the training interventions.At the same time, over the years, numerous innovations and technological advances have been introduced to assist the development of athletes’ performance and monitor individual lifestyles. These advances have changed how training may be conducted, controlled, and evaluated. For example, in sport settings, using technology to collect many and continuous data of athletes’ activity in their natural environments appears as an innovative and promising step. In health, an enormous diversity of training methods supporting healthy lifestyles and innovative approaches is arising, especially from higher-quality information gathered through technological development.Papers addressing these topics are included in this book, especially those combining a high academic standard with a practical focus on providing knowledge on how training methods improve sports performance and health across people's lifespans. New evidence urges us to track the progress and effects of training methods

    History of Construction Cultures Volume 1 contains papers presented at the 7ICCH – Seventh International Congress on Construction History, held at the Lisbon School of Architecture, Portugal, from 12 to 16 July, 2021. The conference has been organized by the Lisbon School of Architecture (FAUL), NOVA School of Social Sciences and Humanities, the Portuguese Society for Construction History Studies and the University of the Azores. The contributions cover the wide interdisciplinary spectrum of Construction History and consist on the most recent advances in theory and practical case studies analysis, following themes such as: - epistemological issues; - building actors; - building materials; - building machines, tools and equipment; - construction processes; - building services and techniques ; -structural theory and analysis ; - political, social and economic aspects; - knowledge transfer and cultural translation of construction cultures. Furthermore, papers presented at thematic sessions aim at covering important problematics, historical periods and different regions of the globe, opening new directions for Construction History research. We are what we build and how we build; thus, the study of Construction History is now more than ever at the centre of current debates as to the shape of a sustainable future for humankind. Therefore, History of Construction Cultures is a critical and indispensable work to expand our understanding of the ways in which everyday building activities have been perceived and experienced in different cultures, from ancient times to our century and all over the world

    Atem / Breath

    The anthology explores breath from the perspective of the arts and humanities, as well as experimental scientific and design practices. Focus is on the period from 1900 to the present day – an era during in which air has become a precarious medium, co-created and manipulated by humans. Against this backdrop, breath appears as an elusive yet vital substance that reveals connections between the physical, symbolic, technological and social realms

    The conservation of monuments and historic sites is one of the most challenging problems facing modern civilization. It involves, in inextricable patterns, factors belonging to different fields (cultural, humanistic, social, technical, economical, administrative) and the requirements of safety and use appear to be (or often are) in conflict with the respect of the integrity of the monuments. The complexity of the topic is such that a shared framework of reference is still lacking among art historians, architects, structural and geotechnical engineers. The complexity of the subject is such that a shared frame of reference is still lacking among art historians, architects, architectural and geotechnical engineers. And while there are exemplary cases of an integral approach to each building element with its static and architectural function, as a material witness to the culture and construction techniques of the original historical period, there are still examples of uncritical reliance on modern technology leading to the substitution from earlier structures to new ones, preserving only the iconic look of the original monument. Geotechnical Engineering for the Preservation of Monuments and Historic Sites III collects the contributions to the eponymous 3rd International ISSMGE TC301 Symposium (Naples, Italy, 22-24 June 2022). The papers cover a wide range of topics, which include:   - Principles of conservation, maintenance strategies, case histories - The knowledge: investigations and monitoring - Seismic risk, site effects, soil structure interaction - Effects of urban development and tunnelling on built heritage - Preservation of diffuse heritage: soil instability, subsidence, environmental damages The present volume aims at geotechnical engineers and academics involved in the preservation of monuments and historic sites worldwide

    Get PDF
    Classical Antiquity is strongly present in youth culture globally. It accompanies children during their initiation into adulthood and thereby deepens their knowledge of the cultural code based on the Greek and Roman heritage. It enables intergenerational communication, with the reception of the Classics being able to serve as a marker of transformations underway in societies the world over. The team of contributors from Europe, North America, Africa, Asia, Australia, and New Zealand focuses on the reception of mythical creatures as the key to these transformations, including the changes in human mentality. The volume gathers the results of a stage of the programme ‘Our Mythical Childhood’, supported by an Alexander von Humboldt Foundation Alumni Award for Innovative Networking Initiatives and an ERC Consolidator Grant. Thanks to the multidisciplinary character of its research (Classics, Modern Philologies, Animal Studies) and to the universal importance of the theme of childhood, the volume offers stimulating reading for scholars, students, and educators, as well as for a wider audience
