Beyond energy efficiency in evaluating sustainable development in planning and the built environment

The EU has set the policy target of reducing energy use by 20% by the year 2020. Therefore, a substantial consumption decrease is needed in the built environment sector. Despite the great energy efficiency improvements in households, recent energy consumption data analyses show that these targets will unlikely be reached. The general aim of this study is to point out the need to define new indicators and evaluation approaches in urban planning and the built environment which are based on the concept of ‘energy subsidiarity', focusing on local renewable resources rather than on current approaches based on energy efficiency. This concept correlates energy consumption with the energy supply from local renewable resources and is here proposed as the new urban planning evaluation approach toward a sustainable built environment. In the paper, the ‘Jevons Paradox' concept and the ‘energy rebound effect' phenomenon are used to demonstrate how current approaches based on energy efficiency, alone, cannot lead to a remarkable reduction of energy consumption. This is also supported by data on European energy consumption and European energy efficiency in the built environment. Finally, a number of well-known European ecological districts (‘eco-districts') are analysed in terms of sustainable energy strategy as well as energy efficiency and energy balance. This study shows that there is a contradiction between the purpose of some of the eco-districts to be low consumption (or low impacts), and the district renewable energy balance. Only a few of the analysed eco-districts are able to cover energy needs by using renewable energy obtained in the surrounding area. In most of the cases, the focus of the districts' activities is on energy efficiency. According to the ‘Jevons Paradox' and ‘energy rebound effect' paradigm, energy efficiency alone will unlikely lead to an effective reduction in resources' consumption. These results point out the need for a radical shift toward the development of new approaches in the assessment and management of the built environment for sustainabilit

Carbon nanotube-based quantum pump in the presence of superconducting lead

Parametric electron pump through superconductor-carbon-nanotube based molecular devices was investigated. It is found that a dc current, which is assisted by resonant Andreev reflection, can be pumped out from such molecular device by a cyclic variation of two gate voltages near the nanotube. The pumped current can be either positive or negative under different system parameters. Due to the Andreev reflection, the pumped current has the double peak structure around the resonant point. The ratio of pumped current of N-SWNT-S system to that of N-SWNT-N system (I^{NS}/I^N) is found to approach four in the weak pumping regime near the resonance when there is exactly one resonant level at Fermi energy inside the energy gap. Numerical results confirm that in the weak pumping regime the pumped current is proportional to the square of the pumping amplitude V_p, but in the strong pumping regime the pumped current has the linear relation with V_p. Our numerical results also predict that pumped current can be obtained more easily by using zigzag tube than by using armchair tube

A Randomized-Trial Evaluation of the Effect of Whose Future Is It Anyway? on Self-Determination

Promoting student involvement in planning has become best practice in the field of transition. Research documents the positive impact of such efforts on greater student involvement. Research also suggests that promoting student involvement results in greater student self-determination, but a causal link has not been established. This study used a randomized- trial, placebo control group design to study the impact of intervention with the Whose Future Is It Anyway? process on self-determination. The authors also examined the impact of intervention on transition knowledge and skills. Results indicated that instruction using the Whose Future Is It Anyway? process resulted in significant, positive differences in self- determination when compared with a placebo-control group and that students who received instruction gained transition knowledge and skills.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Peer expectations about outstanding competencies of men and women medical students

Men and women enrolled in a combined premedical-medical school programme were asked as they began their clinical training to rate their anticipated competence on sixteen criteria relevant to medical practice. Competence dimensions tapped scientific/technical skills, dedication/commitment, and interpersonal skills. Students then were asked to nominate one classmate whom they expected might be‘the best’in each area. Self-ratings revealed few differences among men and women. Peer nominations, however, revealed a preponderance of male nominees in ten competence areas. Women dominated nominations only in the category of sensitivity to patients. Patterns persisted when peer nominations were controlled for students’academic standing and self-ratings on parallel dimensions. The data suggest that medical school peer groups share expectations about competencies of men and women as physicians which are consistent with generalized sex stereotypes and career patterns of men and women physicians.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/74843/1/1467-9566.ep11340055.pd

Meritocratic aspects concerning civil servant career: comparative study in Central and Eastern European countries

Central and Eastern Europe has known in the last 20 years profound changes. The shift from a dictatorial system to a democratic system forced the states from this area to adopt structural measures for all public institutions. In this context, the institution of "civil servant" could not remain unaffected. In the period of communist regimes, the institution of "civil servant" did not exist, the civil servant being just a simple employee of the state. Work relations were the same as for any employee. The shift to another political system, the democratic one, determined the reconsideration the role and the place of public administration, and implicit of civil servant in the framework of the state system. In this context, it has been a shift from the statute of simple employee to that of civil servant, representing the power of the state. In the process of accession to the European Union, the states from Central and Eastern Europe have been permanently pressured to clearly define a strategy concerning the competitiveness of public administration, concerning the statute and the career of civil servant. In the context of democratisation, we can notice that the principle of meritocracy has become a key principle in the civil servant's career. The term "meritocracy" is often used in order to describe a type of society in which wealth and social position are obtained mainly through competition or through ability or proved competences. A position invested with responsibilities and social prestige has to be acquired and not inherited or obtained by arbitrary criteria. Meritocracy represents also the term used to describe or to criticise a society in competition that accepts inequitable disparities of income, wealth and social position. Taking into account the above considerations, the present paper aims to achieve an analysis of meritocratic aspects in the systems of planning and promotion of civil servant's career in Central and Eastern Europe
