Fast computation of spatially adaptive kernel estimates

Kernel smoothing of spatial point data can often be improved using an adaptive, spatially varying bandwidth instead of a fixed bandwidth. However, computation with a varying bandwidth is much more demanding, especially when edge correction and bandwidth selection are involved. This paper proposes several new computational methods for adaptive kernel estimation from spatial point pattern data. A key idea is that a variable-bandwidth kernel estimator for d-dimensional spatial data can be represented as a slice of a fixed-bandwidth kernel estimator in \((d+1)\)-dimensional scale space, enabling fast computation using Fourier transforms. Edge correction factors have a similar representation. Different values of global bandwidth correspond to different slices of the scale space, so that bandwidth selection is greatly accelerated. Potential applications include estimation of multivariate probability density and spatial or spatiotemporal point process intensity, relative risk, and regression functions. The new methods perform well in simulations and in two real applications concerning the spatial epidemiology of primary biliary cirrhosis and the alarm calls of capuchin monkeys.     

The same and the other: male childcare workers managing identity dissonance

As childcare workers, men are in a contested position. On the one hand, they are in danger of being depicted as the pedophile; on the other hand, they are expected to bring something new and innovative to the thus-far female-dominated field. These men are experiencing ‘identity dissonance’ and have to find ways to manage and facilitate legitimate subject positions as both childcare workers and as men. Applying a perspective of discursive positioning, this article discusses men's positioning practices in nine qualitative interviews conducted with male childcare workers in German-speaking Switzerland. We identified a total of six discursive practices that men engage in to manage identity dissonance and construct a legitimate subject position. We found that men are engaging in a greater variety of practices than have been discussed so far. Unlike findings from other studies of men in female-dominated occupations, ours do not point to a clear-cut typology with regards to hegemonic and alternative masculinities; instead they show a variety of practices that are mobilized throughout all interviews.     

The Politics and Poetics of Spaces and Places: Mapping the Multiple Geographies of Identity in a Cultural Posthuman Era

As transcendent technologies, information communication technologies (ICTs) exist beyond the divergent equivalence of human categories of difference such as race, gender, and class, as well as operating outside traditional binary oppositions such as good/bad, love/hate, and rational/irrational. While a material grounding in earlier forms of embodied social experience remains a necessary prerequisite of interaction with virtual systems, a vast collection of technological applications now exhibit some degree of agency as they interact with humans and their environment. This development has enormous consequences for human life, human flourishing, and social organisation, raising significant ethical concerns relevant to public and policy debates. It is, therefore, pertinent to explore key epistemological questions relating to the radical and accelerated remapping of the limits of what it now means to be human. While this article does not purport to offer a pragmatic solution, it constitutes an interdisciplinary conceptual platform from which to consider the nature of the evolving human-nonhuman-machine relationship and the possible implications for humanity, civilisation, and other forms of social organisation in the modern hypermediated world. It is suggested that, by reflecting on the various representations of contemporary technoculture and biotechnology from the perspective of the arts and humanities, it may be possible to isolate those important questions which relate to subjectivity, ethics, community, and social transformation in order to prepare the groundwork for a comprehensive and critical theory of technology.     

Braided geographies: bordered forms and cross-border formations in refugee comics

ABSTRACT

This article offers a close analysis of a trilogy of ‘refugee comics’ entitled ‘A Perilous Journey’, which were produced in 2015 by the non-profit organisation PositiveNegatives, to conceive of comics as a bordered form able to establish alternative cross-border formations, or ‘counter-geographies’, as it calls them. Drawing on the work of Martina Tazzioloi, Thierry Groensteen, Jason Dittmer, Michael Rothberg and others, the article argues that it is by building braided, multi-directional relationships between different geographic spaces, both past and present, that refugee comics realise a set of counter-geographic and potentially decolonising imaginaries. Through their spatial form, refugee comics disassemble geographic space to reveal counter-geographies of multiple synchronic and diachronic relations and coformations, as these occur between different regions and locations, and as they accumulate through complex aggregations of traumatic and other affective memories. The article contends that we need an interdisciplinary combination of the critical reading skills of humanities scholars and the rigorous anthropological, sociological and theoretical work of the social sciences to make sense of the visualisation of these counter-geographic movements in comics. It concludes by showing how the counter-geographies visualised by refugee comics can subvert the geopolitical landscape of discrete nation-states and their territorially bound imagined communities.     

Generations Linked: A Case Example of Māori Grandparents

This article offers an analysis of the significance of intergenerational living patterns and relationships as the mechanisms by which Pacific grandparents preserve and transmit indigenous cultural values, beliefs, and practices. A case example from a study conducted among Māori grandparents in Aotearoa, New Zealand, serves as the core focus of discussion. Seventeen grandparents were interviewed about their lived experiences in their multiple generation homes. Findings indicate that intergenerational life is a means for linking generations and transmission of indigenous culture to the next generation. Participants discussed their intergenerational relationship with much affection and love for their grandchildren and family. Discussion and implications for future research and practice are provided.     

Teaching Note—Description and Preliminary Evaluation of a Modified College Experience for Adults With Intellectual and Developmental Disabilities

ABSTRACT

This article describes the implementation and preliminary evaluation of a modified college experience for adults with intellectual and developmental disabilities (IDD) at a small liberal arts college. To increase social work students’ interest in working with this population and access of people with IDD to higher education, Bridges to Skidmore was founded in 2010 as a low-cost method for providing cooperative learning opportunities for students and individuals with IDD. Preliminary evaluation reveals that participation can change students’ attitudes toward those with IDD, which may increase their intention to work with this population in the future. The program has created an enriching experience for the college students, lecturing professors, and adults with IDD, and can be easily replicated on other campuses.     

Attachment Styles,Loneliness, Quality,and Stability of Marital Relationships

Quality and stability of intimate relationships are determined by various factors. Associations between attachment styles, social and emotional loneliness, competence in being alone, and relationship qualities in couples have not yet been investigated. Sixty-three couples completed self-report measures of current relationship quality and duration, attachment style, and loneliness. Marital quality is predicted by means of experienced emotional loneliness, fearful attachment style, age, and participation in relationship counseling (R ² _corrected = .568). Length of relationship is predicted by age, experienced social loneliness, and competence in being alone (R ² _corrected = .648). Attachment styles, loneliness, age, competence in being alone, and participation in relationship counseling are all possible determinants of relationship qualities.     

Using photography to understand change and continuity in the history of residential care for older people

The Last Refuge by Peter Townsend is a seminal study of residential care for older people. The fieldwork was carried out in the late 1950s and the data are now deposited in the National Social Policy and Social Change Archive at the University of Essex. We have undertaken research, funded by the ESRC, which has revisited Townsend's work and some of the homes he studied in order to conduct an overtime comparison. In this paper we focus on Townsend's use of photography and our subsequent use of photography in our revisiting study. We argue that although Townsend did not analyse his photographs, they were significant data for use in his arguments critiquing residential care. They were, however, the product of a different socio‐historical context to our own and as such posed considerable practical and ethical challenges for us when attempting to use this aspect of his methodology for an overtime comparison. We argue that despite the resulting constraints, photography was an important part of our methodology, enabling comparisons and illuminating historical patterns in residential care for older people.     

Museums as agencies of neocolonialism in a postmodern world

In this article I describe an attempt by a large state museum to engage a plurality of voices and to adopt a new posture of representation in its programmes and exhibitions. In the process however, encumbered with its very institutional nature, of which it made little acknowledgement, it continued to silence much of the plurality to which it hoped to give voice. In the end the museum's discourse of representation of the ‘other’ fundamentally altered very little from its historical posture. I have identified three themes of the colonial heritage of the museums that I suggest encapsulate essential, but not exclusive, dimensions of their hegemony. These are the themes of containment, objectification, and reduction.

As we produce the official explanations, we reproduce the official ideology . . . We are a part of the records that we keep (Spivak 1987: 108).     

Help-Seeking for Sexual Difficulties and the Potential Role of Interactive Digital Interventions: Findings From the Third British National Survey of Sexual Attitudes and Lifestyles

Sexual difficulties are common and can negatively impact health and well-being. A wide range of support is available, but there are multiple barriers to accessing help. Interactive digital interventions (IDIs) for sexual difficulties have the potential to provide a convenient, wide-reaching, and cost-effective source of support, but little is known about who might use them. We explored the potential reach of IDIs by assessing the prevalence of help-seeking among people with distressing sexual difficulties, including who seeks which sources of help. Data came from sexually active men and women, ages 16 to 74, participating in Britain’s third National Survey of Sexual Attitudes and Lifestyles (Natsal-3) (N = 11,637). Help/advice was sought by less than half of those with distressing sexual difficulties, and help-seeking was associated with younger age in women but not men. The most popular sources of support were family doctor (47.5% to 54.8%), Internet (22.0% to 25.6%), and family/friend (20.7% to 41.8%), with older participants (≥ 35), particularly men, preferring to seek help from a family doctor, and younger participants (<35) preferring to seek help from the Internet or family/friend. Despite a paucity of good digital support sites for sexual function, the Internet is a common source of help. As Internet access continues to increase, so too does the potential for well-designed IDIs to support those with sexual difficulties.
