The nation‐state is par excellence a product of ‘modernity’ in Europe. Its supercession has been trumpeted of late, hard on the heels of the fashion for post‐modernity. However, the self‐service conceptions of political identity that pertained until the end of the Cold War now need to be discarded as ethnicity and nationhood evidently become the predominant obsessions of the 1990s. Consequently, ‘Europeanness’ has become a cultural battlefield for sharply divergent views.  相似文献

The ability to model facial expressions by applying shading gradient manipulations to Langer stress lines was assessed in the current experiments. It was hypothesized that the perceived intensity of expressions and the judged faceness of the schematic stimuli would vary as a function of the depth or density of stress lines as measured by shading differences; light and dark contrasts on the facial surface. Expressiveness differences based on the shading manipulations were observed for some stimulus configurations with some differences differentiating the upper and lower halves of the face. The results implicate the shading manipulations as a potential notation system for describing the informational support for the perception of facial expressions, thus providing an empirical measure of relevant stimulus parameters.  相似文献

The likelihood function from a large sample is commonly assumed to be approximately a normal density function. The literature supports, under mild conditions, an approximate normal shape about the maximum; but typically a stronger result is needed: that the normalized likelihood itself is approximately a normal density. In a transformation-parameter context, we consider the likelihood normalized relative to right-invariant measure, and in the location case under moderate conditions show that the standardized version converges almost surely to the standard normal. Also in a transformation-parameter context, we show that almost sure convergence of the normalized and standardized likelihood to a standard normal implies that the standardized distribution for conditional inference converges almost surely to a corresponding standard normal. This latter result is of immediate use for a range of estimating, testing, and confidence procedures on a conditional-inference basis.  相似文献

Client acceptability of treatment procedures has recently become a significant concern in the assessment of psychotherapeutic effectiveness (Kazdin, French & Sherick, 1981; Wolf, 1978). Formally, acceptability refers to the fairness, appropriateness and intrusiveness of the treatment procedure as judged by clients, lay persons and nonprofessionals (Kazdin, 1980a). Unfortunately, marital and family therapists have yet to utilize this criterion in an evaluation of their psychotherapeutic interventions. Consequently, the purpose of the present investigation was to examine the acceptability of four differing therapeutic models (psychoanalytic, behavioral, systems and eclectic) used in the treatment of marital discord.  相似文献

Fertility,Employment, and Child-Care Costs   总被引:7,自引:0,他引:7  
A sample of labor-market and birth histories is used to estimate the effects of child-care costs on employment and fertility decisions. A reduced-form empirical analysis is performed, which is based on hazard functions for transitions among various fertility--employment states. Higher child-care costs result in a lower birth rate for nonemployed women but not for employed women. Higher child-care costs also lead to an increase in the rate of leaving employment and a reduction in the rate of entering employment. The results suggest that potential behavioral effects of child-care subsidies could be significant and should be taken into account when alternative child-care policies are being debated.  相似文献

Summary.  Many health surveys conduct an initial household interview to obtain demographic information and then request permission to obtain detailed information on health outcomes from the respondent's health care providers. A 'complete response' results when both the demographic information and the detailed health outcome data are obtained. A 'partial response' results when the initial interview is complete but, for one reason or another, the detailed health outcome information is not obtained. If 'complete responders' differ from 'partial responders' and the proportion of partial responders in the sample is at least moderately large, statistics that use only data from complete responders may be severely biased. We refer to bias that is attributable to these differences as 'partial non-response' bias. In health surveys it is customary to adjust survey estimates to account for potential differences by employing adjustment cells and weighting to reduce bias from partial response. Before making these adjustments, it is important to ask whether an adjustment is expected to increase or decrease bias from partial non-response. After making these adjustments, an equally important question is 'How well does the method of adjustment work to reduce partial non-response bias?'. The paper describes methods for answering these questions. Data from the US National Immunization Survey are used to illustrate the methods.  相似文献

The purpose of the Cooperative Efforts to Manage Emigration (CEME) site visit to Timisoara, Romania was to evaluate three hypotheses. First, creating the economic conditions that attract Foreign Direct Investment (FDI) brings growth and job creation, which in turn can be expected to reduce emigration pressures and speed the acceptance of Romania into the European Union (EU). The foreign investment initially attracted by low wages will create jobs and hope of continued economic improvement, anchoring workers, managers, engineers, and other professionals to Romania. Over time, jobs and wages will rise, further reducing emigration pressures.
Second, Romania has several sizeable ethnic minorities, notably Hungarians, Germans, Ukrainians, and Roma, or Gypsies. All have a propensity to emigrate. Government policies that reduce discrimination against minorities by respecting their languages and cultures, using public institutions such as the police and schools to demonstrate tolerance and sensitivity to minorities, and enforcing Romania's anti–discrimination laws will reduce emigration pressures in such groups.
Third, the EU and outside organizations can best help to reduce emigration, transit migration, and trafficking by meeting regularly with Romanian officials and non–governmental actors to discuss migration issues in the context of Romania's desire to meet the criteria for EU and NATO membership. This will cause Romanians to take more seriously issues such as the need to integrate Roma into Romania's economy and society, the need to manage borders to prevent trafficking of migrants through the country, and modernizing border management to facilitate the movement of legitimate travellers and goods while discouraging illegal migration.
These hypotheses were borne out by the information gathered at Timisoara, Romania, but actual progress on the measures that would help was found to be very uneven.  相似文献

There are numerous advantages to conducting an evaluation that is based on a strong program theory. However, a careful examination of the field of evaluation indicates that few evaluations are theory based. It is suggested that this discrepancy is caused by significant barriers such as cost, knowledge, motivation, and role confusion. Suggestions for increasing the use of program theory include improving our education and training of evaluators, changing journal policies, and augmenting our methodology for theory development.  相似文献
