THE EFFECTS OF THE RACE OF THE INTERVIEWER ON RACE-RELATED ATTITUDES OF BLACK RESPONDENTS IN SRC/CPS NATIONAL ELECTION STUDIES 总被引:1,自引:0,他引:1
Previous research found substantial effects of the race of theinterviewer on measures of civic attitudes and electoral participationof blacks in NES surveys from 1964, 1976, 1978, 1980, and 1984.This study extends the previous analysis in two ways: it usesdata from two additional NES surveys, 1982 and 1986; and itfocuses on the effects of the race of the interviewer on race-relatedattitudes. Blacks interviewed by whites were much more likelyto express warmth and closeness toward whites than were blacksinterviewed by blacks. But whereas there is no race-of-interviewereffect on blacks' expressions of warmth toward blacks, thereis a clear race-of-interviewer effect on blacks' expressionsof closeness toward blacks. The pattern of responses to thecloseness items appears to result from the format of the question.The observed trend of decreasing expressed closeness of blackstoward blacks in NES surveys between 1976 and 1984 is an artifactof changes in the racial composition of the interviewer staff. 相似文献

EMPLOYER SEARCH, TRAINING, AND VACANCY DURATION 总被引:1,自引:0,他引:1
We develop a model of optimal employer search strategy when information about match quality is endogenous. The model is tested using four data sets, two of which have not previously been used. As theory predicts, we find that when filling positions requiring more training, employers search more intensively and extensively. Employers also search more extensively when hiring workers with more education and with prior experience. These findings provide strong evidence of systematic variation in search strategies based on the characteristics of the positions and job applicants. Factors that influence employer search also affect the duration of a vacancy. 相似文献

We describe two classroom exercises which can be used to reinforce undergraduate students' understanding of (1) production and cost concepts and (2) the concept of economic scarcity. In the first exercise, students use their experience in producing "widgets" in a single variable input environment to derive a wide range of production and cost data. In the second exercise, students use their experience in producing two goods under various allocations of a fixed set of resources to generate a production possibilities frontier. The resulting links between concept and experience enhance students' understanding of these important concepts. 相似文献

An important feature of the German hyperinflation is the way in which accelerating monetization of both government and private debt by the Reichsbank fueled the inflation process. The stimulus to private credit demand arising from more rapid adjustment of money wages over this period is often ignored, however. The present empirical results strongly support the importance of wage pressures in augmenting fiscal influences on nominal money growth during 1920–1923. Our findings also suggest that wage claims provided the main conduit through which higher inflationary expectations were accommodated by faster rates of monetary expansion. 相似文献

TRENDS IN POLITICAL TOLERANCE 总被引:1,自引:0,他引:1
Some researchers find a substantial increase in political tolerancesince the 1950s, while others find the increase to be "illusory"—thepublic is more tolerant now of leftists, but has simply foundother targets on which to vent its intolerance. Reanalysis andthe addition of more extensive trend data from 1940 to 1985suggest that the shift does seem primarily to reflect increasedtolerance of leftists, but that the public has not found othergroups to be intolerant of. Measured tolerance has fluctuatedgreatly over the period, reflecting mainly changes in perceptionsof threat from putatively subversive groups, especially domesticCommunists. Also, the public's grasp of, and selfinterestedconcern about, civil liberties seems so minimal that one mightargue not that the public is substantially tolerant or intolerant,but that it has no really tangibly measurable "attitude" onthe subject one way or the other. 相似文献

Public service announcement (PSA) campaigns have traditionallyrelied on donated rather than paid advertising media. Recently,however, both government agencies and charitable or ganizationshave questioned whether donated-media strategies should be abandonedfor paid-media PSA campaigns. The present research examinesthis issue in a three-market field experiment comparing theeffectiveness of "paid versus donated" PSA cam paigns in decreasingyouthful male drinking and driving. Depen dent variables include(1) self-reports of behaviors from sample surveys and (2) officialcounts of incapacitating and fatal highway accidents. Resultsshow that both campaigns were equally effec tive and both werecost efficient. Thus, in light of these results, it is recommendedthat social marketers not abandon donated-media PSA campaignsfor paid-media PSA campaigns. 相似文献

Numerous social indicators turned negative for Blacks in the 1980s and rebounded a decade later. We explore whether crack cocaine explains these patterns. Absent a direct measure, we construct a crack prevalence index using multiple proxies. Our index reproduces spatial and temporal patterns described in ethnographic accounts of the crack epidemic. It explains much of the 1980s rise in Black youth homicide and more moderate increases in adverse birth outcomes. Although our index remains high through the 1990s, crack's deleterious social impact fades. Changes over time in behavior, crack markets, and the user population may have mitigated crack's damaging impacts. (JEL K42, J15, I30) 相似文献

Les données du Conseil scolaire du district de Toronto sont utilisées pour déterminer quelles sont les répercussions de vivre sous le seuil de faible revenu (SFR) sur le décrochage à l'école secondaire, en tenant compte du statut de la génération d'immigrants ainsi que d'une diversité de facteurs de risques (par exemple, le pays d'origine, l'âge à l'entrée de l'école secondaire, la réussite scolaire). Les résultats ont indiqué que la mesure SFR du voisinage constituait un prédicteur significatif du décrochage scolaire, indépendamment du statut d'immigrant. L'explication du taux de décrochage des immigrants à partir du facteur de la génération n'a obtenu que peu de soutien. La région d'origine s'est avérée un prédicteur marquant du décrochage où l'on constatait des différences entre les groupes d'immigrants et entre les étudiants immigrants et les étudiants originaires du pays. While education statistics confirm that there is little difference in the dropout rates of native‐born and immigrant youth, analyses of Toronto District School Board (TDSB) data have revealed significant variation in school persistence within immigrant groups. Among newcomer youth, the decision to leave school early has been reported to be strongly influenced by socioeconomic status as well as such factors as country of origin, age at arrival, generational status, family structure, and academic performance. While living in low‐income conditions is thought to place both foreign‐ and Canadian‐born youth at risk of poor school performance and early school withdrawal, their substantially higher incidence of poverty suggests that today's immigrant youth are likely to face greater obstacles to academic success that may in turn have detrimental, long‐term consequences. This paper uses TDSB data to investigate the extent to which living below the low‐income cutoff affects the likelihood of dropping out of secondary school, while taking into account generational status as well as a variety risk factors, noted above. Policy implications are discussed. 相似文献

We examine the frequency and conditions of executive departure from S&P 1500 firms. Based upon published news reports, we find that female executives are more likely than male executives to depart their positions voluntarily and involuntarily in the presence of controls for firm performance, firm governance, and human capital. We also find that women are less likely than men to depart voluntarily as firm size increases or board size decreases but more likely to be dismissed as the board becomes more male dominated.
