The European Union (EU) from the beginning of 2007 has focused its emphasis on the development of a new policy that puts energy back at the heart of EU action. Indeed, it has very often been stated that the difficulty and complexity of achieving green energy targets in the EU will require strengthened measures to promote implementation of new energy technologies (NET), as well as measures to support the related energy Research and Technology Development (R&TD). Often forgotten is the fact, that most of all, a European-wide co-ordinated forum is needed to continuously develop and sophisticate the monitoring and methodology results, bringing together specialised statisticians, energy researchers and experts on energy socio-economics. Today a nebulous picture prevails on the existence of categorized data with regards to energy Research and Technology Development (R&TD) expenditure. In this context, aim of this paper is the presentation of energy R&TD data collection strategies, as well as the related findings for the Greek energy market. 相似文献

This study examined an important but rarely investigated aspect of the dissemination process: the intensity of training provided to practitioners. Counselors in 57 schools were randomly assigned to 1 of 3 conditions: Coping Power–training plus feedback (CP-TF), Coping Power–basic training (CP-BT), or a comparison condition. CP-TF counselors produced reductions in children’s externalizing behavior problems and improvements in children’s social and academic skills in comparison to results for target children in both the comparison and the CP-BT conditions. Training intensity was critical for successful dissemination, although the implementation mechanism underlying this effect remains unclear, as condition effects were not significant for completion of session objectives but were significant for the quality of counselors’ engagement with children.

The glass transition temperature of a series of samples of the poly[(methyl methacrylate)‐co‐(ethyl acrylate)] copolymer, synthesized at low conversion, were calculated theoretically using the equations of Barton and Johnston. The values obtained are more precise when the probabilities of the compositional diads are derived from the 13C NMR data instead of the classical method utilizing reactivity ratios. This can be observed more clearly when the copolymer samples are synthesized at high conversion. Introduction of configuration (tacticity) at the diad level confirms the above observations and slightly improves the calculated values of Tg compared to the initial formulae which were only taking into account the compositional sequences of the copolymer. © 2001 Society of Chemical Industry 相似文献

Stable isotope signatures of cattle tail switch hair or meadow vegetation have been found to be related to nitrogen (N) surpluses
of whole farms and of meadows, respectively. Permanent pastures are more patchy in terms of nutrient inputs and outputs and
N balances for the whole plot do not necessarily give correct impressions of losses. We here investigated correlations between
isotopic signatures and N balances calculated for different spatial and temporal scales in permanent pastures. N concentrations
and δ15N values of cattle tail switch hair, vegetation and soil samples were measured in an experiment with different grazing intensities
started in 2002. Results were compared to soil surface balances calculated for the whole plot or for plot areas affected by
either dung, urine, grazing without excreta input, or the pasture area without dung pats. There were no significant correlations
between plant or cattle hair isotopic signatures and any of the balances. N fixation probably influenced vegetation signatures,
making the isotopic values less dependent on soil and more on atmospheric N. The cattle preferred short mixed vegetation with
more legume biomass, which also influenced the 15N values of their hair. The 15N signatures of soil samples were the best indicators of partial N balances in these heterogeneous pastures, probably because
soil values are most directly influenced by N inputs and outputs. Still, soil signatures only explained between 15 and 35%
of the variation in balance results. Thus, none of the tested parameters can be used as a reliable indicator of N balance
results in this heterogeneous system with small differences in budgets among treatments and potentially small plot-scale N
losses. 相似文献

A hierarchical and highly porous carbide-derived carbon (CDC) was obtained by nanocasting of pre-ceramic precursors into cubic ordered silica (KIT-6) and subsequent chlorination. Resulting CDC replica materials show high methane and n-butane uptake and excellent performance as electrode materials in supercapacitors. 相似文献

Four studies present the validation of a self-report scale capturing academic entitlement, which is defined as the tendency to possess an expectation of academic success without a sense of personal responsibility for achieving that success. The Academic Entitlement scale possesses a 2-factor structure (Study 1); 10 items measure students’ Externalized Responsibility for their academic success, and 5 items measure students’ self-serving Entitled Expectations about professors and course policies. In Study 2, the Externalized Responsibility subscale correlated positively with related measures of entitlement, grandiosity, and narcissism, and it was negatively related to self-esteem, personal control, need for cognition, agreeableness, and conscientiousness. In Study 3, participants rated various responses to academic situations selected by university instructors as highly inappropriate or highly appropriate. The Academic Entitlement scale predicted students’ ratings of the appropriateness of these student behaviors as well as the likelihood that they themselves would engage in these behaviors. In a laboratory setting, individuals with high Academic Entitlement scores evaluated the researcher more negatively than those with low Academic Entitlement scores (Study 4). Practical applications are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献
