Arbeitgeber eines Hausbesorgers iSd HBG ist grunds?tzlich nur der Eigentümer eines Hauses. Dies schlie?t aber die analoge Anwendung des HBG in F?llen, in denen eine andere Person als der Hauseigentümer Vertragspartner des Hausbesorgers ist, nicht aus. Auch ein Arbeitsverh?ltnis zu dem, der die Rolle des Hauseigentümers einnimmt – wie etwa zum Gesamtmieter eines Hauses, der sich "in der vollst?ndigen Herrschaft über den Bestandgegenstand wie der Eigentümer befindet" –, unterliegt den Vorschriften des HBG. Nichts anderes kann im Fall des Fruchtnie?ers gelten.  相似文献

Purpose. Researchers have reported that making a Black defendant's race salient reduces White jurors' tendency to find Black defendants guilty ( Sommers & Ellsworth, 2000 ). We examined whether making race salient by including racially salient statements in the defence attorney's opening and closing statements (i.e., ‘playing the race card’) reduced White jurors' racial bias against a Black defendant. Method. We obtained scores on racial attitudes for 151 White college students who participated in an experiment where defendant race (Black, White) and race salience (not salient, salient) were manipulated in a between‐subjects design. Participants read one of four trial stimuli and completed dependent measures. Results. ‘Playing the race card’ reduced White juror racial bias as White jurors' ratings of guilt for Black defendants were significantly lower when the defence attorney's statements included racially salient statements. White juror ratings of guilt for White defendants and Black defendants were not significantly different when race was not made salient. This effect was separate from jurors' level of prejudice (as measured by racial attitudes) as high prejudice participants were more likely than low prejudice participants to find the Black defendant guilty, independent of the race salience manipulation. Conclusion. Our study indicated that an explicit attempt by a defence attorney to ‘play the race card’ was a beneficial trial strategy a defence attorney could use to reduce White jurors' bias towards Black defendants. However, the beneficial effect of such a strategy may not reduce White jurors' bias towards Black defendants for all White jurors.  相似文献

Purpose. The current study explored how misleading information affects children's omissions and commissions over time. Method. Fifty‐nine younger (Mage = 4.16) and fifty‐nine older (Mage = 9.44) children were instructed to remove three pieces of clothing from a puppet. Half of them were provided with false evidence that they had removed only two items, while the other half were provided with false evidence that they had removed a fourth piece of clothing. In three neutral interviews separated by 1‐week intervals, children had to report which pieces of clothing they had removed. Results. Overall, omission and commission errors significantly decreased over time, although this pattern was more pronounced for omission errors. Younger and older children were equally likely to make omission errors, whereas commission errors were more typical for younger than for older children. Also, we found that commission errors more readily occur than omission errors. Conclusion. Even when children's memory reports pertain to an event in which they actively participated, misleading information may elicit omission and commission errors, with especially the latter category being very persistent over time.  相似文献

In this paper, we compare the results from a randomized clinical trial to the results from a regression discontinuity quasi-experiment when both designs are implemented in the same setting. We find that the results from the two approaches are effectively identical. We attribute the comparability in part to recent statistical developments that make the model required for the analysis of data from a regression discontinuity design easier to determine. These developments make an already strong quasi-experimental design even stronger.  相似文献

Based on survey data, collected in 1993 and 1994 from eleven post-communist societies (N = 13,614), the authors investigate empirically the extent to which generations differ in their retrospective evaluations of their defunct Communist political regimes and command economies. While the aggregate level of approval of the old regime varies between countries, within almost every country a similar pattern of generational differences is found: the youngest generation is least approving of the old regime. The generational effect remains when controls are introduced for education. Generational turnover, reinforced by changes in political socialization caused by the collapse of Communist regimes, is eroding nostalgia for a Communist past. And even among generations most nostalgic about the former political and economic orders, there is very little endorsement of a reactionary return to Communist rule.

Abstract

This article examines the impact of New York City's Ten‐Year Plan on the sale prices of homes in surrounding neighborhoods. Beginning in the mid‐1980s, New York City invested $5.1 billion in constructing or rehabilitating over 180,000 units of housing in many of the city's most distressed neighborhoods. One of the main purposes was to spur neighborhood revitalization.

In this article, we describe the origins of the Ten‐Year Plan, as well as the various programs the city used to implement it, and estimate whether housing built or rehabilitated under the Ten‐Year Plan affected the prices of nearby homes. The prices of homes within 500 feet of Ten‐Year Plan units rose relative to those located beyond 500 feet, but still within the same census tract. These findings are consistent with the proposition that well‐planned project‐based housing programs can generate positive spillover effects and contribute to efforts to revitalize inner‐city neighborhoods.  相似文献

Abstract

A comprehensive typology of homeless families would help us understand how to provide services and supports appropriate to particular subgroups. In their attempt to establish such a typology, Culhane and his colleagues employ administrative data sets to correlate shelter use with behavioral indicators. These data sets are limited in that they fail to incorporate the complex, intense, and sometimes traumatic experiences that characterize the lives of homeless families, causing this study to fall short of what is required to create an accurate typology.

Among the areas overlooked by this approach are the high levels of traumatic stress and violence in the lives of homeless families, children's needs, and the interactions between parents and children. When only limited research is available, there is a danger that even modest findings will be used to support broad policy directions. Further research is needed to arrive at a defensible typology.  相似文献
