Data and Model Management in a Generalized MCDM-DSS*

Drawing upon the choice models developed in the multiple criteria decision making (MCDM) area, this paper proposes an architecture for designing an intelligent decision support system (DSS) that is intended to aid in making choices among multiple alternatives along multiple dimensions. It argues that effective support can be provided to the decision maker when the knowledge-based DSS is capable of dynamically selecting choice models appropriate to the domain and context of a particular problem being specified by the decision maker, and of properly applying them to the problem solution. Development of a prototype intended to partially represent application of the architecture is described. The paper concludes with suggestions for research extensions.     

Cleansing violence in the Tajik Civil War: framing from the dark side of democracy

This paper examines the violence in the Tajik Civil War (1992–1997). The actions of both sides mimicked ethnic cleansing as civilian settlements were targeted. The fragmented ethno-regional identities of the republic had historically lived together peacefully, so this style of violence was unanticipated. However, its patterns resemble similar events in the past 40 years that have been examined by other scholars. By conceptualizing it as a modern phenomenon that can be compared to, I develop a better understanding of this form of violence in the Tajik Civil War and place it within scholarly work on ethnic cleansing.     

Building a Social Movement for America's Children

Americans are concerned with the conditions of children and young people, and this concern has proven to be pervasive, intense, and enduring. But it has also largely proven to be politically anemic. Beyond the consensus that children's well-being is threatened, there is little public agreement over who bears responsibility for these problems or what we should do about them. As a result, public unease has failed to translate into a coherent and widespread demand for political change. What explains this gap between public concern and political action when it comes to children's well-being? This paper addresses four aspects of this question: First, in what ways is the public concerned for the well-being of children? Second, why has this concern failed to lead to political mobilization? Third, what factors helped to translate public concern with children in earlier eras into political movements, and why were those movements able to contribute to the policy-making process? Fourth, what might contemporary children's advocacy—reconfigured in light of these insights—look like? Answering these questions sheds light on how collective public will develops and how and when it translates into collective political action benefiting children.

(Trans)Gender Role Expectations and Child Care in Samoa

Samoan transgendered males are known as fa'afafine. Although Samoan women are characterized as the primary child care providers, fa'afafine report elevated willingness to invest in nieces and nephews compared to men and women. We hypothesized that Samoans hold unique transgender role expectations such that fa'afafine are expected to invest more toward nieces and nephews compared to others. Participants (N = 214) included Samoan men (30.23 years ±8.19), women (30.00 years ±10.93), and fa'afafine (30.25 years ±7.45). For a variety of child care activities, participants nominated men, women, fa'afafine, or all three of these categories of individuals as responsible for investing toward nieces and nephews. Participants also reported how frequently their family members asked them to perform these activities for nieces and nephews. Responsibility for performing these activities was typically designated for women; men and women viewed fa'afafine as least responsible. Men's, but not fa'afafine's, family members asked them to allocate investment toward nieces and nephews more frequently. These findings are not consistent with the transgender role expectation hypothesis. Discussion details how the findings contribute to the literature on child care in Samoa. Alternate hypotheses for explaining why fa'afafine report elevated willingness to invest in nieces and nephews are considered.     

Do Children With Gender Dysphoria Have Intense/Obsessional Interests?

This study examined whether children clinically referred for gender dysphoria (GD) show increased symptoms of autism spectrum disorder (ASD). Circumscribed preoccupations or intense interests were considered as overlapping symptoms expressed in GD and ASD. In gender-referred children (n = 534; 82.2% male) and their siblings (n = 419; 57.5% male), we examined Items 9 and 66 on the Child Behavior Checklist, which measure obsessions and compulsions, respectively. Non-GD clinic-referred (n = 1,201; 48.5% male) and nonreferred (n = 1,201; 48.5% male) children were also examined. Gender-referred children were elevated compared to all other groups for Item 9, and compared to siblings and nonreferred children for Item 66. A gender-related theme was significantly more common for gender-referred boys than male siblings on Item 9 only. A gender-related theme was not significantly more common for gender-referred girls compared to their female siblings on either item. The findings for Item 9 support the idea that children with GD show an elevation in obsessional interests. For gender-referred boys in particular, gender-related themes constituted more than half of the examples provided by their mothers. Intense/obsessional interests in children with GD may be one of the factors underlying the purported link between GD and ASD.

Ellipsoidal confidence regions for a normal covariance matrix

We obtain an asymptotic expansion of the confidence coefficient for an ellipsoidal confidence region on the elements of a normal covariance matrix. This leads to simultaneous confidence intervals on all linear functions of the elements of this matrix, which are compared with those of Roy (1954).     

Children and Society Policy Review: Health Policy Affecting Children and Young People

The Health and Social Care Act comes into force in April 2013. It changes the organisation of the health service and accelerates the integration of health and social care. New relationships between primary and secondary healthcare will develop and the culture of clinical and cost effectiveness will expand into social care; work on children in public care is in the vanguard of this change. However, this is not an organisational change designed for children and there are considerable anxieties about how it will impact on the delivery of health care. The issues for children in public care need to stay high on the national agenda and in local fora.     

A multi-resolution census algorithm for calculating vortex statistics in turbulent flows

Summary.  The fundamental equations that model turbulent flow do not provide much insight into the size and shape of observed turbulent structures. We investigate the efficient and accurate representation of structures in two-dimensional turbulence by applying statistical models directly to the simulated vorticity field. Rather than extract the coherent portion of the image from the background variation, as in the classical signal-plus-noise model, we present a model for individual vortices using the non-decimated discrete wavelet transform. A template image, which is supplied by the user, provides the features to be extracted from the vorticity field. By transforming the vortex template into the wavelet domain, specific characteristics that are present in the template, such as size and symmetry, are broken down into components that are associated with spatial frequencies. Multivariate multiple linear regression is used to fit the vortex template to the vorticity field in the wavelet domain. Since all levels of the template decomposition may be used to model each level in the field decomposition, the resulting model need not be identical to the template. Application to a vortex census algorithm that records quantities of interest (such as size, peak amplitude and circulation) as the vorticity field evolves is given. The multiresolution census algorithm extracts coherent structures of all shapes and sizes in simulated vorticity fields and can reproduce known physical scaling laws when processing a set of vorticity fields that evolve over time.
