VALIDATION OF AN IMU-SYSTEM (GAIT-UP) TO IDENTIFY GAIT PARAMETERS IN NORMAL AND INDUCED LIMPING WALKING CONDITIONS

The purpose of this study was to investigate an IMU system (GaitUp) with respect to validity in normal and induced impaired walking by comparing with a state-of-the-art 3D motion capture system. The gait of nine participants was analysed collecting data simultaneously with the GaitUp (Physiolog) placed at each foot and an eight camera motion capture system (Vicon) at 200 Hz each. Participants walked in normal and induced limping (elevation of one shoe) conditions at three walking speeds. For all conditions the two systems yielded similar results regarding the standard gait parameters (gait cycle time, stride length, stride frequency and gait velocity) according to absolute differences and correlation coefficients. GaitUp gathers fairly valid and reliable data in normal and limping walking in a range of walking speed between 0.9 and 2.0 m/s

Disseminating legislative debates: How legislators communicate the parliamentary agenda

While a rich literature addresses legislative agenda-setting in multiparty democracies, relatively little is known how members of parliament disseminate the legislative agenda beyond the parliamentary floor. Drawing on content analyses of 110 legislative debates and 5,847 press releases from Austrian MPs (2013–2017), we test whether legislators are more likely to send press releases on issues that are salient to their party (party agenda-setting) and to other parties in the party system (systemic salience). MPs should also communicate more on issues that fall within their area of expertise (issue specialization) and when they have given a speech on that issue during the legislative debate (intra-party delegation). While we find empirical support for all these expectations, communication of the legislative agenda largely rests on each parties’ issue specialists and their speakers in plenary debates. Importantly, there is no significant discrepancy overall between the actual parliamentary issue agenda and the agenda communicated by party MPs.Austrian Science Fundhttps://doi.org/10.13039/501100002428servicestelle für mobilitätsprogramme des österreichischen bundesministeriums für bildung, wissenschaft und forschung, kulturkontakt austriahttps://doi.org/10.13039/100015057Peer Reviewe

Drought alters timing, quantity, and quality of wood formation in Scots pine

Drought has been frequently discussed as a trigger for forest decline. Today, large-scale Scots pine decline is observed in many dry inner-Alpine valleys, with drought discussed as the main causative factor. This study aimed to analyse the impact of drought on wood formation and wood structure. To study tree growth under contrasting water supply, an irrigation experiment was installed in a mature Scots pine (Pinus sylvestris L.) forest at a xeric site in a dry inner-Alpine valley. Inter- and intra-annual radial increments as well as intra-annual variations in wood structure of pine trees were studied. It was found that non-irrigated trees had a noticeably shorter period of wood formation and showed a significantly lower increment. The water conduction cells were significantly enlarged and had significantly thinner cell walls compared with irrigated trees. It is concluded that pine trees under drought stress build a more effective water-conducting system (larger tracheids) at the cost of a probably higher vulnerability to cavitation (larger tracheids with thinner cell walls) but without losing their capability to recover. The significant shortening of the growth period in control trees indicated that the period where wood formation actually takes place can be much shorter under drought than the ‘potential' period, meaning the phenological growth perio

Atmospheric Deposition and Ozone Levels in Swiss Forests: Are Critical Values Exceeded?

Air pollution affects forest health through atmospheric deposition of acidic and nitrogen compounds and elevated levels of tropospheric ozone (O3). In 1985, a monitoring network was established across Europe and various research efforts have since been undertaken to define critical values. We measured atmospheric deposition of acidity and nitrogen as well as ambient levels of O3 on 12, 13, and 14 plots, respectively, in the framework of the Swiss Long-Term Forest Ecosystem Research (LWF) in the period from 1995 to 2002. We estimated the critical loads of acidity and of nitrogen, using the steady state mass balance approach, and calculated the critical O3 levels using the AOT40 approach. The deposition of acidity exceeded the critical loads on 2 plots and almost reached them on 4 plots. The median of the measured molar ratio of base nutrient cations to total dissolved aluminium (Bc/Al) in the soil solution was higher than the critical value of 1 for all depths, and also at the plots with an exceedance of the critical load of acidity. For nitrogen, critical loads were exceeded on 8 plots and deposition likely represents a long-term ecological risk on 3 to 10 plots. For O3, exceedance of critical levels was recorded on 12 plots, and led to the development of typical O3-induced visible injury on trees and shrubs, but not for all plots due to (1) the site specific composition of O3 sensitive and tolerant plant species, and (2) the influence of microclimatic site conditions on the stomatal behaviour, i.e., O3 uptak

Response of carbon fluxes to the 2003 heat wave and drought in three mature forests in Switzerland

The effects of the heat and drought of the summer 2003 on carbon (C) fluxes (soil CO2 efflux, dissolved organic carbon in soil, C from litterfall and C sequestration in tree) were investigated in three mature forests in Switzerland between 2001 and 2005. Measurements of the soil matric potential (Ψ) indicated a gradient in drought intensity at the three sites (Vordemwald, Schänis, Beatenberg) with average Ψ during the summer 2003 of −75, −41 and −5kPa, respectively. In Vordemwald where the drought was the most severe, the hourly soil CO2 efflux declined by about 30% when Ψ<−90kPa. Estimated annual soil CO2 efflux in 2003 was about 10% smaller than effluxes in wetter years (2001, 2002 and 2004) but the differences were not significant. In Schänis and Beatenberg, no suppression of hourly soil CO2 efflux was observed during the summer 2003. The annual efflux in 2003 at both sites was 10-15% larger than the effluxes in the other years but the differences were not significant. DOC concentrations increased during the first rewetting events after the drought in Vordemwald and in Schänis. This was mainly due to a concentration effect due to the low soil water content. Because precipitation was lower in 2003, annual DOC fluxes substantially decreased at the three sites. Carbon sequestration in tree stems in Vordemwald declined by 32% in 2003 compared to the mean 2002-2005. In Beatenberg and Schänis, tree growth responded little to the extreme summer 2003. Litterfall at the three sites showed no marked reaction to the summer 2003. Estimate of annual net ecosystem production (NEP) suggested that the stands in Vordemwald and in Schänis remained a C sink between 2002 and 2005 but that the extreme summer 2003 caused a decrease in NEP. In Beatenberg, the impact on the NEP seemed to be limited in 2003. The annual NEP in 2003 decreased with increasing drought intensity over the three site

Does exceeding the critical loads for nitrogen alter nitrate leaching, the nutrient status of trees and their crown condition at Swiss Long-term Forest Ecosystem Research (LWF) sites?

Nitrogen (N) deposition exceeds the critical loads for this element in most parts of Switzerland apart from the Alps. At 17 sites (8 broadleaved stands, 8 coniferous stands, and 1 mixed stand) of the Swiss Long-term Forest Ecosystem Research network, we are investigating whether N deposition is associated with the N status of the forest ecosystems. N deposition, assessed from throughfall measurements, was related to the following indicators: (1) nitrate leaching below the rooting zone (measured on a subset of 9 sites); (2) the N nutrition of the forest stand based on foliar analyses (16 sites); and (3) crown defoliation, a non specific indicator of tree vitality (all 17 sites). Nitrate leaching ranging from about 2 to 16kgNha−1a−1 was observed at sites subjected to moderate to high total N deposition (>10kgha−1a−1). The C/N ratio of the soil organic layer, or, when it was not present, of the upper 5cm of the mineral soil, together with the pool of organic carbon in the soil, played a critical role, as previous studies have also found. In addition, the humus type may need to be considered as well. For instance, little nitrate leaching (30kgha−1a−1) but characterized by a C/N ratio of 24, large organic C stocks, and a moder humus type. Foliar N concentrations correlated with N deposition in both broadleaved and coniferous stands. In half of the coniferous stands, foliar N concentrations were in the deficiency range. Crown defoliation tended to be negatively correlated with N concentrations in the needles. In the majority of the broadleaved stands, foliar N concentrations were in the optimum nutritional range or, on one beech plot with high total N deposition (>25kgha−1a−1), above the optimum values. There was no correlation between the crown defoliation of broadleaved trees and foliar concentration
