Popular propositions as to what constitutes a successful single currency area are examined by looking at the Scandinavian Currency Union (1873–1913) formed by Denmark, Norway and Sweden. Applying a frequently used indicator of the desirability of monetary union, we study the symmetry of country-specific structural shocks (measured net of the non-Scandinavian influence) in these three countries. It is found that country-specific shocks are not highly symmetric. This conclusion is also supported by the absence of clear-cut differences between the pattern of structural shocks in Belgium and structural shocks in the Scandinavian countries. This suggests that the three Scandinavian countries did not form an optimum currency area during the period 1873–1913.

Accidents due to ‘fire and flames’ are second only to “falls” as the most important cause of accidental death in the homes of elderly individuals throughout the United Kingdom. This study aims to ascertain whether older people are receiving fire accident advice appropriate to their needs. A questionnaire addressing the issues of risk perception, fire preventative action and access to fire safety information was distributed to 1100 randomly selected members of the ‘Thousand Elders’ (a nation-wide consumer group established by the Centre for Applied Gerontology at The University of Birmingham, comprising people above the age of 50 years). Eight hundred and four questionnaires were returned and were analysed using the Statistical Package for Social Sciences. Fire risk was perceived as far less of an immediate threat than the danger of a personal attack by an intruder in the home. Recognition of fire risk and the effectiveness of fire safety measures did not result directly in safety appliances being fitted. The majority of ‘Elders’ had received no fire-fighting training, yet more than half felt confident in tackling a small fire. Neither did experience of a fire in the home necessarily increase action towards safety precautions. The majority had not been exposed to a fire safety campaign in the past 12 months. On exposure to a campaign, the impact towards fire safety was positive. The educational process should aim to close the gap between the recognition of the need for fire safety precautions and the implementation of fire safety measures. The key to effective fire prevention amongst older people depends upon: Information, Training and Support, i.e., relevant information supported by practical help and subsequent practical training in-situ by trusted community figures. 相似文献

We develop a model for economic growth applicable to a group of countries, constituting around half of the gross global production,
that have been consistently “catching up” to the US since 1960 or so. This group can be termed “the convergence club.” The
model has a theoretical basis developed in other publications (cited), but the present work is essentially empirical. It demonstrates
that there is a very strong correlation between “catchup” growth, with respect to the US, and an energy proxy (EP). The energy
proxy that works best is a linear combination of domestic electric power consumption petroleum (oil) consumption, per capita,
compared to the US levels. The results presented here do not constitute a theory of growth, but they are consistent with theory
presented elsewhere. On a practical level, we argue that consistent “catchup” trends over the past 40 years can safely be
extrapolated for a few more decades for scenario construction purposes. We also believe that the observed catchup trends can
be regarded as “potential” mid-term or long-term growth trajectories for transition economies and others that have recently
been adversely affected by conflict or mismanagement. 相似文献

This paper describes a new approach for closing the gap between the tools for strategic goal management and operational management in Pharmaceutical R&D. The strategic level may concern with expectation of sales, rising from new products and with total R & D budget. The operational level concerns with project selection, project and multiproject management problems, solution of project related technical problems, determination of the size of the various functions and the functional management. This new method combines the R & D project portfolio management with a steady state concept allowing the attainment of a constant number of projects under development and a continuous full use of the capacity available. 相似文献
