High-frequency water quality measurements in streams and rivers have expanded in scope and sophistication during the last two decades. Existing technology allows in situ automated measurements of water quality constituents, including both solutes and particulates, at unprecedented frequencies from seconds to subdaily sampling intervals. This detailed chemical information can be combined with measurements of hydrological and biogeochemical processes, bringing new insights into the sources, transport pathways, and transformation processes of solutes and particulates in complex catchments and along the aquatic continuum. Here, we summarize established and emerging high-frequency water quality technologies, outline key high-frequency hydrochemical data sets, and review scientific advances in key focus areas enabled by the rapid development of high-frequency water quality measurements in streams and rivers. Finally, we discuss future directions and challenges for using high-frequency water quality measurements to bridge scientific and management gaps by promoting a holistic understanding of freshwater systems and catchment status, health, and function.

In Sweden, snuff-use is an established and accepted phenomenon in society, especially in connection with certain sports. The aim of this qualitative study was to analyze and describe the psychosocial environment influencing young male ice-hockey players into starting to use snuff. The study sample comprised 16 male participants between 15 and 32 years of age strategically selected for being active or having been active as ice-hockey players--snuff-users and non-users alike. A grounded theory design, including in-depth interviews, was used to generate a theory from data and thereby create theoretical concepts explaining social phenomena, human behavior, and process. An interview guide containing different themes was used to cover the study area. Five higher-order categories were developed and labeled: having a role model, residing in a consenting environment, experiencing performance demands, experiencing a sense of community and creating an image. Socialization in and through psychosocial norms of the ice-hockey environment was identified as a core category describing the central meaning of the informants' experiences of snuff in the ice-hockey environment. In the present study, the identified categories that integrate within the environment in which the young people reside and pursue their sports activities have been interpreted as factors enhancing the commencement of snuff-use. We suggest health promotion activities within the ice-hockey environment based on a health psychology model of planned behavior.

Background The health care of today stands in front of demands on financial and structural changes. New technology and global economy are forces driving on the change process. Aims The aim of this study is to describe and broaden the understanding of the employees experience of being involved in a merge between two health care districts in Sweden. Methods This study was carried out from a qualitative approach according to the grounded theory tradition. From a theme guide with specific questions, 31 interviews were carried out with employees working in the health care. Findings Five categories emerged from the body of interviews: balancing involvement, trust respect, challenge and commitment. Balancing involvement was defined as an overall core category related to the other categories. The categories trust, respect, challenge and commitment were related to subcategories and affected the core category balancing involvement. Conclusions The overall findings point to the importance of balancing the employees involvement in order to reach goal fulfilment change in a merger process., Distrubution: Via tidskriften eller via http://Blackwell-synergy.com
