AbstractIn this installment of “Conversations,” Dominic Boyer, Cymene Howe, and Marcel LaFlamme, of the Cultural Anthropology editorial team, discuss the ins and outs of publishing a gold open access journal in the field of anthropology. Highlights of the discussion include Cultural Anthropology’s move to open access, the ethics of open access, the growth of international readership, ongoing publishing challenges in open access, and the role libraries can play with open access publishing. 相似文献

This article describes estimation and inference procedures for the parameters of the Box-Cox and foided-power transformations in repeated measures and growth curve models. Procedures for computing maximum likelihood estimates of the transformation and covariance parameters under several covanance structures (omnibus sphericity, local sphericity, and unstructured) are described. Lack of fit statistics and hypothesis tests for comparing these structures also are described. The procedures are illustrated on three data sets. Software for performing the analyses in the SAS System is described and is available from the authors. 相似文献

Attempts to grapple with the complicated tangle of race and memory are more prominent than ever in the public discourse of the United States. In 2006, public intellectual Henry Louis Gates sought to popularize the search for roots and meaning with his project African American Lives, and in 2007 the black and white descendants of the landmark Plessy v. Ferguson case met in New Orleans to discuss the past and present significance of their ancestors’ lives. As the crafting of identities around increasingly fluid notions of ‘race’ proceeds apace, the activities of family historians provide a useful entrée into struggles over race, identity, and collective memory in the United States. The research reported here illustrates how the shared history of the multi-racial descendants of eighteenth and nineteenth century St Domingue/Haiti in Louisiana is encountered in racially distinct ways. Participant observation is used to examine how race is dealt with in the activities of two groups: 1) a mainly European American genealogical society, called the St Domingue Special Interest Group; and 2) the LA Creole cultural and genealogy group, made up primarily of Louisiana creoles of color. Preliminary findings indicate that while the process of engaging in family history research provides an opening for some participants to better understand others across racial and ethnic divides, this kind of cross-racial dialogue was limited by the organization of family history activities into racially distinct social networks. As the popularity of genealogy increases, the findings here point to the need to recognize the public significance of these private histories. 相似文献

Breslow and Holubkov (J Roy Stat Soc B 59:447–461 1997a) developed semiparametric maximum likelihood estimation for two-phase
studies with a case–control first phase under a logistic regression model and noted that, apart for the overall intercept
term, it was the same as the semiparametric estimator for two-phase studies with a prospective first phase developed in Scott
and Wild (Biometrica 84:57–71 1997). In this paper we extend the Breslow–Holubkov result to general binary regression models
and show that it has a very simple relationship with its prospective first-phase counterpart. We also explore why the design
of the first phase only affects the intercept of a logistic model, simplify the calculation of standard errors, establish
the semiparametric efficiency of the Breslow–Holubkov estimator and derive its asymptotic distribution in the general case. 相似文献

Large firms face a conflict in managing a portfolio of high-risk projects. When an ongoing project is thought to have a low likelihood of success, project team members take risks to improve its chances of success. However, upper-level managers who allocate resources tend to withhold resources from a project with a low likelihood of success in favor of others in the portfolio that look more promising. Because this paucity of resources influences project team members to avoid risk, the total effect of success likelihood on risk taking is conflicted. The influence on risk taking of a project's terminal value—defined as the value that remains in the firm in the event of project failure—is unequivocally positive, because both senior management resource allocation and project team risk-taking propensity are encouraged by terminal value. Thus, firms can override the ambivalent effect of likelihood of success on project decision making by focusing attention on a project's terminal value. 相似文献

This study examined whether the efficacy of keepin' it REAL, a model program for substance use prevention in schools, was moderated by gender, ethnicity, and acculturation. Gender differences in program efficacy may arise through boys' higher risk of drug use, inadequate attention to girls' developmental issues, or cultural factors like polarized gender expectations. Data came from a randomized trial in 35 Phoenix, Arizona, middle schools involving 4,622 mostly Latino 7th graders. Using multi-level mixed models and multiple imputation missing techniques, results for the total sample showed no gender differences in program effects on recent substance use, but the program was more effective in fostering boys' than girls' anti-drug norms. Subgroup analyses demonstrated several more beneficial program effects for boys than girls (less alcohol and cigarette use and stronger anti-drug norms), but only among less acculturated Latinos. There were no gender differences in program effects among more acculturated Latinos, nor among non-Latino whites. 相似文献
