This paper reports the results of a research carried out on environmental performance in companies with an environmental management
system registered under the EMAS regulation. By applying an empirical approach, the article analyses the trend of the environmental
performance of a sample of 64 Italian companies pertaining to 6 different industrial sectors, which have achieved EMAS registration
for at least three years. The trends of the environmental indicators included in the environmental statements, officially
validated by a third party and traceable to a period of time before and after the registration, were collected and evaluated.
In particular, the influence of the EMAS registration on the improvement or the worsening of the environmental performance
was analyzed and thus the ability of this instrument to pursue continuous improvement, a founding principle of environmental
management certification schemes. Data obtained indicate that in some cases, EMAS leads to an actual improvement of environmental
performance, even in the short period. 相似文献

The EMAS Regulation (Reg 761/01 EC) is EU scheme implemented by the European Commission since 1993 and it is for the implementation of an Environmental Management System (EMS) by any organization. The EMS was originally proposed by the European Commission and by the ISO as the frontrunner of a series of policy tools that enable companies to simultaneously pursue environmental objectives and competitive targets in a synergetic way.Based on the unique dataset of the EVER project, this paper investigates whether or not an EMS implemented within the EMAS Regulation has any effect on firm performance both from an environmental and a competitive point of view. Our econometric analysis shows the positive impact of a well-designed environmental management system on environmental performance and, as a consequence, on technical and organizational innovations. Effects on other competitive variables such as market performance, resource productivity and intangible assets are not strongly supported. 相似文献

In goitred gazelles (Gazella subgutturosa), sexual dimorphism of larynx size and position is reminiscent of the case in humans, suggesting shared features of vocal
ontogenesis in both species. This study investigates the ontogeny of nasal and oral calls in 23 (10 male and 13 female) individually
identified goitred gazelles from shortly after birth up to adolescence. The fundamental frequency (f0) and formants were measured
as the acoustic correlates of the developing sexual dimorphism. Settings for LPC analysis of formants were based on anatomical
dissections of 5 specimens. Along ontogenesis, compared to females, male f0 was consistently lower both in oral and nasal
calls and male formants were lower in oral calls, whereas the first two formants of nasal calls did not differ between sexes.
In goitred gazelles, significant sex differences in f0 and formants appeared as early as the second week of life, while in
humans they emerge only before puberty. This result suggests different pathways of vocal ontogenesis in the goitred gazelles
and in humans. 相似文献
