Residential building codes intended to promote health and safety may produce unintended countervailing risks by adding to the cost of construction. Higher construction costs increase the price of new homes and may increase health and safety risks through income and stock effects. The income effect arises because households that purchase a new home have less income remaining for spending on other goods that contribute to health and safety. The stock effect arises because suppression of new-home construction leads to slower replacement of less safe housing units. These countervailing risks are not presently considered in code debates. We demonstrate the feasibility of estimating the approximate magnitude of countervailing risks by combining the income effect with three relatively well understood and significant home-health risks. We estimate that a code change that increases the nationwide cost of constructing and maintaining homes by $150 (0.1% of the average cost to build a single-family home) would induce offsetting risks yielding between 2 and 60 premature fatalities or, including morbidity effects, between 20 and 800 lost quality-adjusted life years (both discounted at 3%) each year the code provision remains in effect. To provide a net health benefit, the code change would need to reduce risk by at least this amount. Future research should refine these estimates, incorporate quantitative uncertainty analysis, and apply a full risk-tradeoff approach to real-world case studies of proposed code changes.  相似文献

Labour migration to the Gulf countries is predominantly contract based and a majority of workers fall below the salary ceiling necessary for sponsoring family members. Despite this, social networks have expanded in Kuwait, primarily in the form of sponsorship of additional labour migrants by those already in the country.
The objectives of the article are to describe how the process of arranging sponsorship works, to delineate the predictors of moving through a friend or relative, or arranging sponsorship for a subsequent labour migrant, and to assess the "multiplier" effect of the above process. The article is based on a survey among 800 South Asian skilled and unskilled male migrants, 200 each from Bangladesh, India, Pakistan and Sri Lanka.
About 34 per cent of all respondents moved through friends or relatives, 50 per cent through agents and 16 per cent through direct hiring or the government bureau. Logistic regression analysis indicated that the factors most likely to predict a move through the social network consisted of being a Pakistani or Indian, being a Muslim, and possessing some skills.
One-quarter of all migrants had arranged the visa for another migrant since they came to Kuwait. Logistic regression analysis showed the respondent's duration of stay in Kuwait to be an exceptionally important predictor for arranging sponsorship for an additional migrant.
Monthly income, being married and being a Muslim were also positively associated with arranging sponsorship. In terms of the multiplier effect, about 0.78 visas had been arranged per migrant. Pakistanis, who had the longest average duration of stay in Kuwait, arranged the maximum number (1.6) of visas on average.  相似文献

Drug addict rehabilitation programs receive a small proportion of the funds made available through the social welfare system. Emphasis has traditionally been placed on the pathological rather than the salutogenic elements of an addicted lifestyle. A new test of a person's sense of coherence in life (Antonovsky's 9-item Sense of Coherence scale) may be of interest in rehabilitation work with drug addicts, and in focusing more attention on this aspect of addiction treatment. Thirty drug addicts in treatment and rehabilitation and 10 former drug addicts were interviewed using the 9-item Sense of Coherence scale. The results obtained were compared to a well known test of distress, the 24-item Symptom Checklist. Drug addicts in treatment facilities had significantly lower mean scores on the 9-item Sense of Coherence scale (2.3) and higher scores on the 24-item Symptom Checklist (2.3) than both drug addicts in rehabilitatively oriented institutions (3.3 and 1.6) and the long-term rehabilitated non-using former drug addicts (4.2 and 1.5 respectively). The differences between the group in rehabilitation and the former drug addicts were also statistically significant. The levels of the two psychometric tests suggested a gradual movement towards normal values and an increased sense of meaning in life among the former drug addicts, contrary to findings by other researchers. The length of time before these tests return to normal values may exceed the observation period often used in follow-up at treatment facilities. Increased social welfare may follow if a disclosure of salutogenic possibilities in drug addicts is obtained. Further prospective research is, however, necessary to confirm our findings.  相似文献

A study of 240 YMCA organizations revealed that regardless of organization size, those organizations that used a formal approach to strategic planning had higher levels of financial and social performance than those with less formal processes. The better performers also assigned the responsibility for planning to a strategic planning subcommittee of the board rather than to the board's executive committee or to an outside consultant.  相似文献

The design, aims and rationale are outlined of a follow-up study of dropouts from Gamblers Anonymous. A cohort of those attending for the first time and dropping out after more than one meeting was contacted and the cooperators given a structured interview examining factors which may have contributed to decisions to dropout. A comparison group of continuers from the same meeting who had been totally abstinent for at least a year were given the same structured interviews. This first of four parts examines life context factors making it more difficult to maintain attendance, commitment to the treatment program, perceived pre-meeting expectations and reasons for coming, impacts of the first meeting, effects of pressures to maintain attendance and the influence of spouses.  相似文献

Social compromise and social metrics   总被引:1,自引:0,他引:1  
In the context of constitutional design, a committee of citizens' representatives proposes (social choice) axioms. The outcome should not necessarily be the aggregation rule, or rules, satisfying each of the axioms. Alternative procedures are recommended for aggregating a set of axioms into a single summary axiom. The summary axiom generates a single social decision function when a social metric is applied.  相似文献
