Electronic government is attested to have the potential to shape public administrations to be more customer oriented. In order to be customer oriented, municipalities need knowledge about customer needs. Which municipalities explore customer needs and what do they change is investigated using data of a nationwide survey about e-government in Switzerland. 相似文献

(International) R&D collaboration and SMEs: The effectiveness of targeted public R&D support schemes
This study analyses the impact and effectiveness of targeted public support for R&D investment at the firm level. We test whether the policy design aiming at incentivizing (international) collaboration and R&D in SMEs achieves input as well as output additionality. Our results show that the targeted public subsidies trigger R&D spending, especially so in internationally collaborating SMEs. We further evaluate the different impact of privately financed and publicly induced R&D investment on innovation performance. The results confirm that the publicly induced R&D is productive as it translates into marketable product innovations. While both types of R&D investments trigger significant output effects, the effect of policy-induced R&D investment on sales from market novelties is highest for international collaborators as well as for SMEs. 相似文献

The aim of the study was to examine the effects of three different training models on aerobic power and body composition in recreationally active runners. According to their preferences 54 subjects (female=?27, male?=?27) were assigned to the following groups: (a) weekend group (WE), who performed two sessions of continuous endurance training weekly, (b) after-work group (FE) who carried out four sessions of high intensity training as well as an additional endurance run and (c) STAR group (STAR), who took part in a training with exercise telemetry monitors based on the heart rate variability. Over the 12-week study period the mean training volume was approximately 2 h 15 min per week. Of the participants 47 successfully completed the training study and all 3 groups showed significantly improved aerobic power (p?<0.001); however, the FE group (d?=?1.15) showed increased VO2max superior to WE (d?=?0.48) and STAR (d?=?0.66) groups. Significant improvements in body mass (p?<?0.001), body fat (p?<?0.001) and visceral fat (p?<?0.001) were found in the WE, FE and STAR group. All groups completed the half marathon with no significant differences in performance. Based on a similar training volume, short, intensive endurance training sessions of about 30 min were found to elicit the greatest improvements of VO2max in recreationally active runners. 相似文献

ABSTRACTExercise at different cadences might serve as potential stimulus for functional adaptations of the brain, because cortical activation is sensitive to frequency of movement. Therefore, we investigated the effects of high (HCT) and low cadence training (LCT) on brain cortical activity during exercise as well as endurance performance.Cyclists were randomly assigned to low and high cadence training. Over the 4-week training period, participants performed 4 h of basic endurance training as well as four additional cadence-specific exercise sessions, 60 min weekly. At baseline and after 4 weeks, participants completed an incremental exercise test with spirometry and exercise at constant load with registration of electroencephalogram (EEG).Compared with LCT, a greater increase of frontal alpha/beta ratio was confirmed in HCT. This was based on a lower level of beta activity during exercise. Both groups showed similar improvements in maximal oxygen consumption and power at the individual anaerobic threshold.Whereas HCT and LCT elicit similar benefits on aerobic performance, cycling at high pedalling frequencies enables participants to perform an exercise bout with less cortical activation. 相似文献

Two sets of quality measures of group care were used to assess their predictive power for two sets of measures of the development of infant and toddlers in group day care. One of the quality measures we investigated was the Early Childhood Environment Rating Scale (ECERS). We replicated the findings of Scarr, Eisenberg, & Dealer-Deckard (1994) which were that the total score of the ECERS represents a global index and that the 37 items making up the scale are redundant and could be shortened considerably without loss of the scale as a quality criterion of group care for young children. Neither Scarr, Eisenberg, and Dealer-Deckard (1994) nor our own Factor Analyses of the 37 items supported the a priori distinction of seven Subscales. However further findings indicate that regardless of the redundancy within ECERS, two Subscales, dealing mainly with adult-child, child-child and adult-adult interactions, predict the development of infants and toddlers, but only when the measures of development were based on participant observations of the children over a longer period of time and in the broad context of the natural daycare environment. None of the Subscales, nor the total ECERS predicted social development when it was based on precise time sampling observations, assessed by non participant observers, in interactions between a child and a specific caregiver. Such measures of development were well predicted in our study by caregiver behaviors assessed through Time Sampling Observations. 相似文献
