Pea-barley intercrop N dynamics in farmers fields

Knowledge about crop performances in farmers’ fields provides a link between on-farm practice and re-search. Thereby scientists may improve their ability to understand and suggest solutions for the problems facing those who have the responsibility of making sound agricultural decisions. Nitrogen (N) availability is known to be highly heterogeneous in terrestrial plant communities (Stevenson and van Kessel, 1997), a heterogeneity that in natural systems is often associated with variation in the distri-bution of plant species. In intercropping systems the relative proportion of component crops is influenced by the distribution of growth factors such as N in both time and space (Jensen, 1996). In pea-barley intercrops, an increase in the N supply promotes the growth of barley thereby decreasing the N accumulation of pea and giving rise to changes in the relative proportions of the intercropped components (Jensen, 1996). The pres-sure of weeds may, however, significantly change the dynamics in intercrops (Hauggaard-Nielsen et al., 2001). Data from farmers’ fields may provide direct, spatially explicit information for evaluating the poten-tials of improving the utilisation of field variability by intercrops

A novel approach to probe host-pathogen interactions of bovine digital dermatitis, a model of a complex polymicrobial infection

Background: Polymicrobial infections represent a great challenge for the clarification of disease etiology and the development of comprehensive diagnostic or therapeutic tools, particularly for fastidious and difficult-to-cultivate bacteria. Using bovine digital dermatitis (DD) as a disease model, we introduce a novel strategy to study the pathogenesis of complex infections. Results: The strategy combines meta-transcriptomics with high-density peptide-microarray technology to screen for in vivo-expressed microbial genes and the host antibody response at the site of infection. Bacterial expression patterns supported the assumption that treponemes were the major DD pathogens but also indicated the active involvement of other phyla (primarily Bacteroidetes). Bacterial genes involved in chemotaxis, flagellar synthesis and protection against oxidative and acidic stress were among the major factors defining the disease. Conclusions: The extraordinary diversity observed in bacterial expression, antigens and host antibody responses between individual cows pointed toward microbial variability as a hallmark of DD. Persistence of infection and DD reinfection in the same individual is common; thus, high microbial diversity may undermine the host's capacity to mount an efficient immune response and maintain immunological memory towards DD. The common antigenic markers identified here using a high-density peptide microarray address this issue and may be useful for future preventive measures against DD.Fil: Marcatili, Paolo.

Non-Verbal Interactions Between Music Therapists and Persons with Dementia. A Qualitative Phenomenological and Arts-Based Inquiry

When music therapists are supervising caregivers in how to apply music in their interactions with persons with dementia, we may term this as indirect music therapy practice. Musical interactions are mostly happening through nonverbal, implicit, and embodied knowledge, and, therefore, there is a need for exploring and verbalizing such interactions for music therapists to be able to disseminate to caregivers and other professionals. In this qualitative study, we examine how 6 music therapists with clinical experience in dementia care experience nonverbal interaction with persons with severe dementia living in nursing homes. Explorative focus groups were conducted to study the music therapists’ lived-experience descriptions about their nonverbal interactions with persons with dementia. Focus group transcripts were analyzed by a phenomenological approach, and the findings elaborated and peer validated by the use of musical improvisation as an arts-based analytic approach. The findings included five themes: vitality, disciplined subjectivity, attunement, therapeutic presence, and validation. The music therapists were guided by the vitality of the person with dementia, were aware of their own reactions, and sensed the needs of the person through disciplined subjectivity. They attuned to the person’s nonverbal musical parameters (e.g., tempo pitch and volume) and cocreated an open and mutual field through therapeutic presence and validation. The findings are relevant for future development of direct and indirect music therapy practice but contain limitations due to a homogenous and small group of participants. This study highlights the challenges of exploring nonverbal and musical interactions with the use of language-based methods of inquiry.publishedVersio

Trade Union Participation and Influence at Norwegian Workplaces During the Pandemic

A central feature of the Nordic model of labor relations, namely, the collaboration between social parties at the workplace, has proven to be particularly effective during crises. This is the backdrop for our study of the experiences from Trade Union Representatives (TU-reps) during the corona pandemic. With a survey aimed at TU-reps from the Norwegian Confederation of Trade Unions (LO), which represents just under half of the total unionized employees, we asked how the pandemic affected their participation and influence at the workplaces. Referring to the pandemic as a game changer, we discuss signs of change in TU-reps’ possibilities for participation and influence under such difficult circumstances.  According to theTU-reps, interaction between the social parties intensified during the pandemic. Formal participation between the parties stands out to be crucial for enabling dialog and can therefore be labeled as the backbone of the Nordic model in times of crisis
