Surface Estimation, Variable Selection, and the Nonparametric Oracle Property

Variable selection for multivariate nonparametric regression is an important, yet challenging, problem due, in part, to the infinite dimensionality of the function space. An ideal selection procedure should be automatic, stable, easy to use, and have desirable asymptotic properties. In particular, we define a selection procedure to be nonparametric oracle (np-oracle) if it consistently selects the correct subset of predictors and at the same time estimates the smooth surface at the optimal nonparametric rate, as the sample size goes to infinity. In this paper, we propose a model selection procedure for nonparametric models, and explore the conditions under which the new method enjoys the aforementioned properties. Developed in the framework of smoothing spline ANOVA, our estimator is obtained via solving a regularization problem with a novel adaptive penalty on the sum of functional component norms. Theoretical properties of the new estimator are established. Additionally, numerous simulated and real examples further demonstrate that the new approach substantially outperforms other existing methods in the finite sample setting.     

Superheroes and third-wave feminism

Recent developments in superhero comics have seen positive changes to the representation of characters and storylines. In this article, we use examples of the increase in female characters and female-led titles, the swapping of gender from a male character to a female one, and the increase in female writers and artists to investigate how the representation of female characters has evolved. We argue that these changes mark an intervention on behalf of female creators in keeping with the theory and practice of third-wave feminism. We also argue that this evolution provides a good example of how third-wave feminism remains indebted to and continues the important work of second-wave feminism. The article explores the important role of intersectionality alongside themes relating to the body and sexuality, violence, solidarity and equality, and girlhood in comics such as Birds of Prey, Harley Quinn, Ms. Marvel, Captain Marvel, and A-Force.     

Home Futures: Living in Yesterday’s Tomorrow? Home Futures,An Exhibition by the Design Museum,London in Partnership with IKEA Museum,Almhult – 2018-9

ABSTRACT

Home Futures, the major exhibition at the Design Museum, London, and IKEA Museum Sweden, explores the trajectory of radical domestic visions from the 1960s—but it seems that the future was closer in the 1960s than now.     

Cultural Schemas of Religion,Science, and Law in Talk About Social Controversies

We analyze cultural schemas of religion, science, and law reflected in the way ordinary citizens discuss contemporary social controversies and assess whether these schemas accord with a modernization narrative or whether people's experiences with each of these institutional arenas lead them to adopt realistic or critical schemas not predicted by modernization accounts. Focus group participants in three metropolitan areas were asked to talk about one of three vignettes on faith‐based prison ministries, parents’ refusal of medical treatment for a child on religious grounds, or preimplantation genetic diagnosis of human embryos. We find that people's everyday experiences, grounded in specific institutional contexts, produce perceptions of the domains of religion, science, and law that are not fully captured by the modernization account. Further, our findings illustrate that schemas of law, science, and religion are varied and evoked by social context and the specific issues under consideration. Schemas that do not fit the modernization framework provide a way for people to address concerns about power and effectively level the playing field between more and less rationalized social domains. Future research on a broader range of issues is needed to develop a theory of when different schemas of law, science, and religion are activated.

Widening the gap: White ignorance,race relations and the consequences for Aboriginal people in Australia

White ignorance has a critical impact on race relations and is implicated in the maintenance of Aboriginal disadvantage. Addressing this ignorance is a largely overlooked capacity-building opportunity within Australia's non-Aboriginal population. It warrants consideration as a key component of strategies targeting Aboriginal disadvantage. Despite the established links between race relations and Aboriginal well-being, Aboriginal perspectives on non-Aboriginal people rarely feature in public discourse on “Aboriginal problems.” This paper draws on data from 180 in-depth interviews with 44 Aboriginal people in Darwin on the topic of White Australian people, culture and race relations. It reports Aboriginal perceptions of White Australian ignorance across areas of great symbolic and practical significance to Aboriginal people's lives. Their experience is that most White Australians are ignorant of the history of colonisation and the complexities of its aftermath. They are ignorant of Aboriginal law, cultures and languages, and of the extent of their own ignorance. The call to address White ignorance subverts assumptions about whose ignorance and capacity must be dealt with in order to progress national goals of reconciliation, address Aboriginal disadvantage and achieve justice and equality for Aboriginal people.     

Population recovery in New Orleans after Hurricane Katrina: exploring the potential role of stage migration in migration systems

In this research brief, we explore how places affected by natural disasters recover their populations through indirect, or “stage,” migration. Specifically, we consider the idea that post-disaster impediments (e.g., housing and property damage) in disaster-affected areas spawn migration flows toward and, over time, to disaster-affected areas through intermediary destinations. Taking as our case Orleans Parish over a 5-year period after Hurricane Katrina, we show that stage migration accounted for up to about one-fourth of population recovery. We close by discussing the implications, limitations, and potential extensions of our work.     

'Ladettes' and 'Modern Girls': 'troublesome' young femininities

‘Ladettes’ are argued to be a sign, and product, of contemporary development and change; their fortunes are presented as inextricably related to the conditions of late modernity. Using the past to shed light on the present, this paper considers whether fears and claims about the behaviour of some contemporary young women in Britain are exclusive to the present. Two data sets inform the discussion: first, representations of ladettes in national and local newspapers from 1995 to 2005; second, materials relating to the ‘modern girl’ published in the popular print media between 1918 and 1928. Although there have been important changes in the conditions of girlhood since the 1920s, this historical comparison highlights continuities in the representation of ‘troublesome’ youthful femininities. We explore similarities and differences in the characteristics attributed to the modern girls of the twenties and the ladettes of recent years, and the dominant discourses that underpin popular constructions of troublesome young women.     

Severe borderlines and self psychology

This paper will discuss work with a woman diagnosed as having borderline personality disorder because of classic symptoms of intense unstable affect, recurrent suicidality, self-mutilation, and primitive defensive organization. Once a selfobject transference tie was established, the borderline symptoms remitted. Discussion of this case will focus on the clinical application of concepts from the field of psychoanalytic self psychology, particularly the concepts of self-object functions and intersubjectivity, in work with patients diagnosed as borderline.
