The western United States offers a case study on the importance of access to large population centers and their markets, via road and air travel, for economic development. The vast distances between towns and cities in the American West can be a detriment to business, yet they also serve to attract technology and knowledge-based workers seeking to live in a picturesque setting. In spite of the increasing importance of amenities to migration and business location, also needed is access to markets, particularly via commercial air service. We test a new county classification system for the western United States to reflect differing degrees of access to population centers and account for the increasing importance of airports. Past classifications are based on population size and cross-county commuting. We examine the validity of this new classification and test for differences in economic performance among the three county types. Our findings show that there are three distinct Wests that can be classified using economic performance measures and socioeconomic characteristics. The results show that “metro” and “isolated” counties are clearly distinct, but “connected” counties, those that are rural in nature but have ready access to metropolitan areas via air travel, can be difficult to distinguish from “metro” and “isolated” counties. Much of the variation is explained by travel distance to airports. The findings illustrate the importance of airports in rural development, and the limitations facing those communities that are isolated from markets and population centers. The results apply to other parts of the world with similar characteristics that include large expanses of open space, natural amenities that attract migrants and stimulate new business, and different degrees of access to large population centers via road or air travel, and therefore different rates of economic growth. 相似文献

The increasing role for chosen friends is a key element in current debates on individualization and the transformation of intimacy. This paper describes the changes in friendship choices over time and demonstrates how life events subsequently impact on those choices. We primarily distinguish between kin and non-kin nominations of friends and how these may be related to the social and economic turbulence inherent in late modernity. Analyses of data from ten years of the British Household Panel Survey showed that kin nominations still form a significant proportion of all friends but increasingly so with age and over time as people age. Life events, such as divorce or death of a partner, have large effects on the likelihood of changes in friendship choices as did gender, age, marital status and social class. We frame these results in a discussion of the saliency and nature of friendship at stages of the life course and conclude that the case for a general secular shift to choosing non-kin friendships rather than kin-based friendship is not demonstrated. 相似文献

Computer systems are constantly under the threats of being attacked and in many cases these attacks succeed. Today’s networked
systems are thus built to be intrusion tolerant. In a large scale, the progresses of compromising the networked system and
recovering the damage will carry on in parallel, allowing services to be continued (at a degraded level). One of the key problems
in the restoration procedure regards to the resource allocation strategies and the cost associated with, specifically, a minimal
cost is desired. In this paper we model the cost as a sum of service loss and resource expense that incur during the restoration
procedure. We investigate the achievable minimal total cost and corresponding resource allocation strategy for different situations.
The situations include both constant rates and time-variant rates in terms of the speed of compromising and recovering. We
also consider the fact that the restoration rate is constrained by the resource allocated. The relationship can be either
linear or obeying the law of diminishing marginal utility. We present both analytical and numerical results in the paper. The results show the impact from various system parameters
on the critical conditions for a successful system restoration and on the minimal cost.

In this paper, an attempt has been made to construct the physical quality of life index (PQLI) for some countries and for the Indian States as well. Three important indicators, viz. literacy rate, infant mortality rate and life expectancy at birth, reflecting the quality of life have been chosen and combined with equal weights to obtain PQLI. The rationale of equal weights, apart from any subjective judgement, may also be found in a mathematical model presented here. It is observed that PQLI rises sharply with per capita GNP but after a certain stage, an increase of per capita GNP is not accompanied by an increase of PQLI. 相似文献

Most parents or carers who separate or divorce are able to makearrangements themselves about where their children will resideand how the childrens contact with the non-resident parentwill be managed. A further group of parents or carers are ableto come to agreement with the assistance of community- or court-baseddispute resolution/ mediation services. There are times, however,when disputes cannot be resolved without recourse to the courtsand, when this happens, the court will normally request thata welfare report be prepared by a CAFCASS (Children and FamilyCourt Advisory and Support Service) practitioner. While theboundary between assessment and intervention in social workis often less than clear, the commissioning of a court welfarereport in family proceedings strongly suggests an assessmentfocus and appears to carry little expectation that the practitionershould intervene in order to meet the needs of the childrenor adults involved. This article presents recent research findingsthat illustrate ways in which CAFCASS practitioners do go beyondthe assessment role expected of them in the course of the enquiriesthey undertake. Implications for policy and practice in thisarea of social work are then discussed. 相似文献
