    Significant results have been obtained from the analyses of ERTS-1 imagery from five cycles over Test Site SR 124 by classical photointerpretation and by an interactive hybrid multispectral information extraction system (GEMS). The synopticity, periodicity and multispectrality of ERTS coverage, available for the first time to LA County planners, have opened up both a new dimensionality in data and offer new capability in preparation of planning inputs. Photointerpretation of ERTS images has produced over 25 overlays at 1:1,000,000 scale depicting regional relations and urban structure in terms of several hundred linear and areal features. To mention only one such result, a possible new fault lineament has been discovered on the northern slope of the Santa Monica mountains in the scene 1144-18015, composited of MSS bands 4, 5, 6,. GEMS analysis of the ERTS products has provided new or improved information in the following planning data categories: urban vegetation; land cover segregation; man-made and natural impact monitoring; urban design; and suitability. ERTS data analysis has allowed planners to establish trends that directly impact planning policies. This new source of information will not only assist current methods to be more efficient, but permits entirely new planning methodologies to be employed

    Project Overview: This project is an outgrowth of the Public Service Program of the Center for Groundwater Science (CGS) at the Illinois State Water Survey. For over 50 years, the CGS has provided groundwater information to any requesting individual, commercial facility or public water facility. Groundwater resource assessments have been an integral part of this public service and have been undertaken for thousands of individuals and facilities throughout its history. Community groundwater supplies that have been identified as potentially “deficient” are the targets for this project. The criterion used for determining community deficiency were; 1) Water Supply and Demand (operating time), 2) Aquifer Limitation, 3) Well Specific Capacity, and 4) Facility History. The Village of Ashmore has been identified as a target community for groundwater assessment through this project. Project Goal: To provide a resource tool of pertinent groundwater information to each target facility. This document describes a summary of historic information, current conditions and the potential for expansion of the water supply within 5 and 10 miles of Ashmore.Ope

    Tourism income and economic growth in Greece: Empirical evidence from their cyclical components

    Get PDF
    This paper examines the relationship between the cyclical components of Greek GDP and international tourism income for Greece for the period 1976–2004. Using spectral analysis the authors find that cyclical fluctuations of GDP have a length of about nine years and that international tourism income has a cycle of about seven years. The volatility of tourism income is more than eight times the volatility of the Greek GDP cycle. VAR analysis shows that the cyclical component of tourism income is significantly influencing the cyclical component of GDP in Greece. The findings support the tourism-led economic growth hypothesis and are of particular interest and importance to policy makers, financial analysts and investors dealing with the Greek tourism industry

    Economic Relations between the EU and CIS (An Overview)

    The purpose of this paper is to examine the economic aspects of EU policy towards its Eastern neighbors in the former Soviet Union. For a long period of time, this region was considered as less important for the EU, as compared to Central and Eastern Europe, which was the subject of a far-reaching economic and political integration offer materialized in two rounds of EU Eastern Enlargements (2004, 2007). However, moving the EU's geographical frontier further to the East and Southeast increased the importance of the CIS region as a potential partner of the enlarged EU. In 2004, East European and Caucasus countries were invited to participate in the European Neighborhood Policy a new EU external policy framework also addressed to the Southern Mediterranean countries. Russia has been attempting to build a strategic political and economic partnership with the EU outside the ENP framework but the content of this relationship is, in fact, very similar to the ENP. A general weakness of the ENP is that there is a lack of balance between farreaching expectations with respect to neighbors' policies and reforms, and limited and distant rewards that can potentially be offered. Thus, making this cooperation framework more effective requires a serious enhancement of the rewards using, to the extent possible, the positive experience of previous EU enlargements. The nature of contemporary economic relations in the globalized world calls for a more complex package-type approach to economic integration rather than just limiting cooperation to some narrow fields

    Relationship between spatial proximity and travel-to-work distance : the effect of the compact city

    Get PDF
    In this paper, an assessment is made of the relationship between selected aspects of spatial proximity (density, diversity, minimum commuting distance, jobs-housing balance and job accessibility) and reported commuting distances in Flanders (Belgium). Results show that correlations may depend on the considered trip end. For example, a high residential density, a high degree of spatial diversity and a high level of job accessibility are all associated with a short commute by residents, while a high job density is associated with a long commute by employees. A jobs-housing balance close to one is associated with a short commute, both by residents and by employees. In general, it appears that the alleged sustainability benefits of the compact city model are still valid in a context of continuously expanding commuting trip lengths

    China\u27s hegemonic intentions and trajectory: Will it opt for benevolent, coercive, or Dutch‐style hegemony?

    Get PDF
    China\u27s unprecedented economic growth led some scholars to conclude that it will replace the United States as the future global hegemon. However, China\u27s intentions in exercising future global leadership are yet unknown and difficult to extrapolate from its often contradictory behaviour. A preliminary overview of China\u27s island building in the South China Sea reveals its potentially coercive intentions. This inference is consistent with the analysis of those who prognosticate China\u27s violent rise. Conversely and simultaneously, China\u27s participation in peacekeeping operations and its global investments evince its benevolent hegemonic intentions, which are congruent with the argument of those who predict China\u27s peaceful hegemonic ascent. Confronted with these divergent tendencies in China\u27s recent international relations, and assuming its continued rise, it is, thus, essential to examine China\u27s strategic intentions and how these may ultimately project its violent or peaceful hegemonic rise. This article argues that the “Third Way” or “Dutch‐style” hegemony is highly instructive in this context and, thus, should be examined and added to the existing debate on China\u27s rise as either a benevolent or coercive hegemon. We argue that Dutch‐style hegemony may be the most viable way for China to proceed in its global hegemonic ascendancy

    The prospects for environmental accounting and accountability in China

    Get PDF
    Foucault’s ideas on episteme change are used to help understand change taking place in China from the “industrial civilization” to an “ecological civilization”. If episteme change is taking place this could be reflected in the philosophies and attitudes of Chinese accountants and their environmental accounting work will be developing. The conclusions are that: China is slowly moving towards an ecological civilisation; based around the thinking of Chinese accountants an epistemic change is in evidence in tandem with an emerging interest in ancient Chinese philosophy; Chinese accountants’ engagement with environmental accounting and accountability is evidence of reduced specialisation

    Spontaneous coronary artery dissection: Current state of the science: A scientific statement from the American Heart Association

    Get PDF
    © 2018 American Heart Association, Inc. Spontaneous coronary artery dissection (SCAD) has emerged as an important cause of acute coronary syndrome, myocardial infarction, and sudden death, particularly among young women and individuals with few conventional atherosclerotic risk factors. Patient-initiated research has spurred increased awareness of SCAD, and improved diagnostic capabilities and findings from large case series have led to changes in approaches to initial and long-term management and increasing evidence that SCAD not only is more common than previously believed but also must be evaluated and treated differently from atherosclerotic myocardial infarction. High rates of recurrent SCAD; its association with female sex, pregnancy, and physical and emotional stress triggers; and concurrent systemic arteriopathies, particularly fibromuscular dysplasia, highlight the differences in clinical characteristics of SCAD compared with atherosclerotic disease. Recent insights into the causes of, clinical course of, treatment options for, outcomes of, and associated conditions of SCAD and the many persistent knowledge gaps are presented
