Guidelines for implementation of the National Environmental Policy Act state that environmental impact statements (EISs) shall
use “appropriate graphics.” We examined one component of graphics, typography, identifying applicable criteria from the literature
and applying them to 150 EISs prepared by seven agencies. We found that the EISs ranged widely in typographic quality. The
average EIS met fewer than seven of ten criteria; 12% were considered unreadable. The results suggest that weak typography
may seriously limit public review of EISs. Agencies are encouraged to make typography a serious component of their public
participation programs. 相似文献

Management of natural environment sites is becoming increasingly complex because of the influx of urbanized society into wildland areas. This worldwide phenomenon impacts a wide range of countries. In southern California ethnicity is often a major factor influencing recreation site use and behavior at sites in the wildland-urban interface. This study investigated the role of ethnicity and race on the use patterns, perception of environment, and recreation behaviors at an outdoor recreation site visited by an ethnically diverse population. Two research questions were asked: (1) What ethnic groups engage in outdoor recreation at this site, and (2) what differences can be assigned to these various groups? Data were collected from 250 recreationists during 1991. Three major ethnic groups were identified, and statistically significant differences were found in the importance of site attributes, activity participation, and in preferred and actual communication channels. Management implications and strategies based on group differences are discussed. 相似文献

The present study aimed at investigating the influence of shop steward characteristics and early union socialization experiences on new members' attitudes toward unions and their affective commitment to the union. Two thousand surveys were mailed to the most recent members of the National Association of Letter Carriers. Of these, 658 (33 per cent) were returned. Focusing on those individuals who had joined the union within the past 12 months yielded a usable sample of 585. A two-stage, structural equation modeling approach indicated a satisfactory goodness-of-fit for both the measurement and structural models. Individual socialization experiences significantly affected union attitudes. The latter variable was a significant predictor of union commitment. These results are discussed in the context of the organizational socialization literature and union commitment research. 相似文献

ABSTRACT: Although droughts are a frequent occurrence over much of the United States, response by state and federal government has been ineffective and poorly coordinated. Recently, several states have recognized the value of drought emergency planning and have developed plans to assist them in responding more effectively to prolonged periods of water shortage. These states have created an organizational structure to coordinate the assessment and response activities of state and federal agencies. Each state's drought response plan is unique since each state's water supply and management problems, and their consequent impacts, are unique. The drought response plans developed by Colorado, South Dakota and New York are reviewed here in detail. We recommend that other states affected by frequent and severe water shortages also develop drought emergency plans. These plans will enhance state government's ability to implement effective measures in a timely manner and, ultimately, may provide added incentive for the federal government to develop the national drought response plan called for by the General Accounting Office in 1979. 相似文献

ABSTRACT: Macroinvertebrate community data collected from streams in Wyoming were assessed at various scales: within one stream reach, between stream reaches within one stream, between streams, and between stream classes. Fourteen indices including number of individuals/m2, biomass/m2, number of taxa, Shannon's diversity index, and functional feeding group ratios were used to compare macroinvertebrates by stream reach and stream class. Statistical analysis indicated that for five of the 14 indices, significant variability occurred between macroinvertebrate communities within one reach. For two of the remaining nine indices there was significant variability between communities from several reaches within the same stream. For seven of the nine indices, there was significant variability among macroinvertebrate communities from streams of the same class. Variability among the macroinvertebrate communities from the three stream classes was significantly different for seven of the nine indices. ANOVA results suggest that macroinvertebrate communities from different samples within one reach and between reaches within one stream were more comparable than those from different streams and different stream classes. 相似文献

Summary.
Rhabdophis tigrinus obtains defensive steroids (bufadienolides) from its diet and sequesters those compounds in specialized structures on its
neck known as nuchal glands. Hatchling snakes lacking these steroids must acquire them from toads consumed as prey. Here we
show that females provision bufadienolides to their offspring in amounts correlated to the quantity in their own nuchal glands;
thus, chemically protected mothers produce defended offspring. Bufadienolides can be provisioned to embryos via deposition
in yolk and by transfer across the egg membranes within the oviducts. Maternally provisioned bufadienolides persist in the
nuchal glands of juvenile snakes from the time of hatching in late summer until the following spring, when toads of ingestible
size become abundant. Therefore, maternal provisioning may provide chemical protection from predators for young R. tigrinus in the absence of dietary sources of bufadienolides. 相似文献

The European Union (EU) transition to a smarter and more sustainable electricity sector is driven by climate change adaptation and technological developments. For the electricity distribution industry, this has contributed to a growing need to understand how these network monopolies should adapt their role, activities, and responsibilities for a redesigned electricity market, given the growth of distributed generation, and the increased control and monitoring capabilities. Considering this, a foresight study on business model innovation, technological adaptation, and market design policy alternatives is presented. A Policy Delphi method was applied, involving two iterative survey rounds and 207 European experts, which assessed 57 policy alternatives. The results highlight adaptation challenges for implementing new technologies and business practices. Experts support innovation and transition to new roles, and innovative services, while warranting that core electricity distribution activities are secured. This shift in roles is expected to be achieved through research and development (R&D) support policies, innovation friendly regulatory frameworks, and concerted actions at the EU and Member States level. The results provide policy-adaptation guidelines for electricity distribution industry stakeholders. 相似文献
