This article summarizes gaps between assumptions that appear in the literature, research, and accepted standards for marital and family therapy (MFT) supervision, and the common practice of supervisors. Issues that stem from these gaps are highlighted and recommendations are made for closing them. In an effort to refine the standard of practice for MFT supervision, best practice recommendations are offered for MFT supervision. 相似文献

Classical group testing (CGT) is a widely applicable biotechnical technique used to identify a small number of distinguished
objects from a population when the presence of any one of these distinguished objects among a group of others produces an observable result. This paper discusses a variant of CGT called group testing for disjoint pairs (GTAP). The difference between the two is that in GTDP, the distinguished items are pairs from, not individual objects in,
the population. There are several biological examples of when this abstract model applies. One biological example is DNA hybridization.
The presence of pairs of hybridized DNA strands can be detected in a pool of DNA strands. Another situation is the detection
of binding interactions between prey and bait proteins. This paper gives a random pooling method, similar in spirit to hypothesis
testing, which identifies pairs of objects from a population that collectively have an observable function. This method is
simply to apply, achieves good results, is amenable to automation and can be easily modified to compensate for testing errors.

In recent years, the labor movement has expressed interest in using the community as a source of union power in dealing with
employers. This paper explores labor’s historical relationship with the community, examines the emphasis on more effective
uses of the community in core union activities, identifies the communities with which labor aligns itself in coalitions, and
discusses the strategies employed to form alliances with community groups. Finally, an analysis of some of the key barriers
and limitations that affect prospects of the formation and effectiveness of union-community coalitions is presented.

In the absence of a clinical definition of Behaviour Disorder, those termed ‘Behaviourally Disordered’ are often considered unsuitable for psychiatric servicing and many end up inappropriately contained by the correctional system. The working definitions of 213 South Australian health and welfare professionals from six client areas (child/adolescent, psychiatric, intellectually disabled, brain-damaged, correctional and general) were surveyed. Respondents generally saw Behaviour Disorder as a recognisable disorder, involving both aggressive, disruptive behaviour and deficits in social adaptation. Perceptions of its presentation varied across client groups and across professional roles. The results highlighted a need for specialised community servicing for this group. 相似文献

Between 1970 and 1990, China experiencoed a rapid and sharp fertility decline—from total fertility rates of approximately six births to two. The degree to which Chinese fertility has continued to fall after 1990 is controversial. We use survey data from the 1997 National Population and Reproductive Health Survey and from the 2001 Reproductive Health and Family Planning Survey to document recent trends in Chinese fertility. Our estimates provide further evidence that China's fertility is well below‐replacement level at the turn of the twenty‐first century—with TFR levels of approximately 1.5 children per woman. Trends in parity‐specific cohort fertility by age also suggest below replacement completed fertility for cohorts still in the childbearing years. In the article's second section, we identify key components of low period fertility in order to frame our discussion of two questions: 1) in what ways is Chinese low fertility different from/similar to that in other low‐fertility countries? And 2) what are the likely future trends in Chinese fertility? 相似文献

Using data from the 1979 National Longitudinal Survey of Youth, we describe the correspondence between intended family size and observed fertility for US men and women in the 1957–64 birth cohorts. Mean fertility intentions calculated from reports given in the mid‐20s modestly overstate completed fertility. But discrepancies between stated intent and actual fertility are common—the stated intent at age 24 (for both women and men) is more likely to miss than to match completed fertility. We focus on factors that predict which women and men will have fewer or more children than intended. Consistent with life‐course arguments, those unmarried, childless, or (for women) still in school at approximately age 24 were most likely to underachieve their intended parity (i.e., had fewer children than intended at age 24). We discuss how such discrepancies between intentions and behavior may cumulate to produce sizable cross‐group fertility differences. 相似文献

The magnitude of racial differences in first birth timing vary greatly depending upon the data sources from which they are estimated. Vital registration data (Heuser 1976; with updates from the National Center for Health Statistics 1974–1990) show that in recent years nonwhites have higher risks of a first birth at virtually all ages compared to whites. As a result very large and historically novel differentials in childlessness are forecast using these data (see Rindfuss et al. 1988; Chen & Morgan 1991; Morgan & Chen 1992). However, retrospective fertility history data collected from the 1980, 1985 and 1990 Current Population Surveys (CPS) suggest much smaller racial differences in completed childlessness and isolate racial differences in probabilities of first births at young ages. Differences also exist between theses two series for whites prior to the mid-1960s but not afterwards. Reasons for these differing estimates are suggested and examined. We conclude that a substantial portion of the differences result from an accumulation of biases in the vital registration estimates that affect primarily estimates of first birth timing. Thus, the CPS data provide a more firm basis for racial comparisons of first birth timing. 相似文献

Five sampling schemes (SS) for price index construction – one cut-off sampling technique and four probability-proportional-to-size (pps) methods – are evaluated by comparing their performance on a homescan market research data set across 21 months for each of the 13 classification of individual consumption by purpose (COICOP) food groups. Classifications are derived for each of the food groups and the population index value is used as a reference to derive performance error measures, such as root mean squared error, bias and standard deviation for each food type. Repeated samples are taken for each of the pps schemes and the resulting performance error measures analysed using regression of three of the pps schemes to assess the overall effect of SS and COICOP group whilst controlling for sample size, month and population index value. Cut-off sampling appears to perform less well than pps methods and multistage pps seems to have no advantage over its single-stage counterpart. The jackknife resampling technique is also explored as a means of estimating the standard error of the index and compared with the actual results from repeated sampling. 相似文献
