Investigating the Relationship Between Real Estate Agents,Segregation, and House Prices: Steering and Upselling in New York State

This article leverages a unique data set, recently developed regression methods, and qualitative interviews to investigate the multiple ways real estate agents produce housing inequality. We find that the clustering of agents in and around certain neighborhoods correlates positively with house prices. Our results also show a significant relationship between agent concentration and racial segregation. Our qualitative data reveal how agents engage in steering and upselling. The findings enhance our understanding of mechanisms in the housing market, and provide more empirical clarity on the role real estate agents play in asset and place inequality.

Progression-free survival in oncological clinical studies: Assessment time bias and methods for its correction

Progression-free survival (PFS) is a frequently used endpoint in oncological clinical studies. In case of PFS, potential events are progression and death. Progressions are usually observed delayed as they can be diagnosed not before the next study visit. For this reason potential bias of treatment effect estimates for progression-free survival is a concern. In randomized trials and for relative treatment effects measures like hazard ratios, bias-correcting methods are not necessarily required or have been proposed before. However, less is known on cross-trial comparisons of absolute outcome measures like median survival times. This paper proposes a new method for correcting the assessment time bias of progression-free survival estimates to allow a fair cross-trial comparison of median PFS. Using median PFS for example, the presented method approximates the unknown posterior distribution by a Bayesian approach based on simulations. It is shown that the proposed method leads to a substantial reduction of bias as compared to estimates derived from maximum likelihood or Kaplan–Meier estimates. Bias could be reduced by more than 90% over a broad range of considered situations differing in assessment times and underlying distributions. By coverage probabilities of at least 94% based on the credibility interval of the posterior distribution the resulting parameters hold common confidence levels. In summary, the proposed approach is shown to be useful for a cross-trial comparison of median PFS.     

Avoid falling for a jerk(ette): Effectiveness of the Premarital Interpersonal Choices and Knowledge Program among Emerging Adults

Premarital education may help emerging adults form healthy relationships, but evaluation research is needed, particularly with community samples. We studied emerging adults in the Premarital Interpersonal Choices and Knowledge (PICK) program, using a pre‐ to post‐ and a posttest‐then‐retrospective‐pretest design to examine change in perceived relationship skills, partner selection, relational patterns, and relationship behaviors and attitudes. Mixed models analyses showed that scores for the treatment group (n = 682) increased from pre to post on all four outcomes. Changes in scores for the nonequivalent comparison group (n = 462) were nonsignificant. In addition, significant differences between pre‐ and retrospective prescores demonstrated evidence for response shift bias. The results suggest that the PICK program helps participants increase their knowledge regarding the components of healthy relationship formation.     

Technological capital and digital divide among young people: an intersectional approach

This article explores the digital divide among young people in Spain by examining four traditional socio-demographic variables (gender, age, education and employment situation). It proposes the concept of ‘technological capital’ as a means to put people’s socioeconomic conditions of existence into relation with the different forms of accessing and using Information and Communication Technologies (ICT). Methodologically, a quantitative approach is taken, based on the National Statistics Institute’s survey of ICT Equipment in households, which makes use of both bivariate and multivariate analysis. Finally, a typology of young users of the Internet is proposed (1 – Digitally Excluded; 2 – Basic Users; 3 – Users in Mobility; 4 – Cyber Consumers; 5 – Cyber Experts) which takes into account the importance of technological capital, the socio-economic position and cultural resources of subjects in their incorporation of ICTs into their daily life.     

Terrorism Risk Assessment,Recollection Bias,and Public Support for Counterterrorism Policy and Spending

Recollection bias (RB) refers to the phenomenon whereby after an adverse event people report that their risk assessment about a similar future event is presently no higher than their recollection of their pre‐event risk assessment. While previous research has outlined this theoretical construct and generated important empirical findings, there were some limitations. We design and employ a new national representative survey to address these limitations in this study. We examine the existence and persistence of RB among the general public in the context of a number of domestic and international terrorist attacks. We further examine the socioeconomic and political base of RB and the influences of RB on a wide range of citizens’ counterterrorism policy preferences. Our data analyses reveal strong evidence showing the occurrence of RB and its persistence across various forms of terrorism risk. With regard to the socioeconomic and political base, we find that females, older people, political conservatives, and Republicans are less likely to be subject to RB. For the effects of RB on public counterterrorism policy preferences, our analyses demonstrate that this bias significantly dampens public support for a wide range of preventive policy measures and government anti‐terrorism spending. Overall, our study, based on a national representative sample and an extended survey design, provides robust evidence of RB in terrorism risk assessment, and adds further evidence to support the idea that RB is likely a generalizable phenomenon. Implications and suggestions for future research are discussed in the conclusion.     

Ties,sites and irregularities: pitfalls and benefits in using respondent-driven sampling for surveying a homeless population

Respondent-driven sampling (RDS) is a survey method for hidden populations and, as such, it offers a suitable approach for sampling the homeless. Surprisingly, the practical use of RDS in surveying homeless populations has only sporadically been described in the professional literature so far, and the specifics of using RDS for sampling this group have not been reflected in depth. The goal of the article is to investigate how three specific concerns, namely the transitional character of social ties among the homeless, problems with locating the interview site, and the irregular use of coupons, affect the sampling process. The findings of the article are based on experience using RDS for creating two independent samples of homeless persons in two Czech cities. Worries of poor referral effectiveness were disproved, but poor validity of the network size indicator, tendency towards irregular use of coupons, and negative effects arising from selecting service centres for the homeless as survey sites were confirmed.     

Effect of Perceived Crisis Response on Consumers' Behavioral Intentions During a Company Scandal – An Intercultural Perspective

In the context of a multi-national company scandal, namely Volkswagen's Dieselgate, we examine the effect of customers' perception of organizational crisis response on their revenge and avoidance intentions in different cultural settings. Using data collected in the US and in Germany, we are able to show that the perception of appropriate crisis response reduces customers' revenge as well as avoidance intentions. However, due to the domestic bias of German respondents, the mechanism linking perception of the organization's crisis response to the respective outcomes differs between Germany and the US. Our results demonstrate for the first time that domestic bias is not always associated with being an amplifier of positive factors; rather, in the context of an organizational scandal, it dampens the effects of organizational crisis response.
