Embedding quantitative skills into the social science curriculum: case studies from Manchester

Those aiming to respond to the recognised shortage in quantitative skills within the UK social sciences have increasingly focused on the content of undergraduate degree programmes. Problems occur when quantitative methods are generally confined to a dedicated module, detached from substantive topics. This model makes it hard for students to understand or engage with the contribution of quantitative research to their discipline and can perpetuate negative perceptions of quantitative training. We suggest a solution to this problem is ‘quantitative embedding’, in which quantitative evidence and methods are incorporated into substantive teaching in the social sciences. We illustrate quantitative embedding with case studies from an ESRC funded project based in The University of Manchester, where teaching partnerships have developed curriculum innovations in Sociology and Politics. The paper then discusses the challenges of disseminating quantitative embedding, highlighting the need to bridge separate communities of practice that can isolate quantitative specialists.     

Psychological Wellbeing Among Same‐sex Attracted and Heterosexual Parents: Role of Connectedness to Family and Friendship Networks

Increasing numbers of lesbian, gay and bisexual (LGB) adults are entering into parenthood. Previous studies indicate many of these parents receive little or no support from their families of origin due to family members' negative attitudes toward homosexuality. This study looks at the extent to which LGB parents report a lower sense of connectedness to family of origin and friendship networks than heterosexual parents and whether this has an impact on psychological wellbeing in either of these groups. Data were derived from two studies of parents: Work, Love, Play, a study of Australian and New Zealand LGB parents (n=324); and the Longitudinal Study of Australian Children, a population‐based study of young children and parents (n=6460). Structural equation modelling was used to explore the relationships between: parent sexuality and family/friendship connectedness, family/friendship connectedness and psychological wellbeing, parent sexuality and psychological wellbeing. LGB parents reported feeling less connected to their families of origin but more connected to their friendship groups than heterosexual parents. Counter to previous studies, we found no difference in the psychological wellbeing of LGB parents compared to heterosexual parents when examining the direct effect of sexuality on psychological wellbeing. Clinical implications for counsellors and family therapists are discussed.     

International surveys of educational achievement: how robust are the findings?

Summary.  International surveys of educational achievement and functional literacy are increasingly common. We consider two aspects of the robustness of their results. First, we compare results from four surveys: the Trends in International Maths and Science Study, the Programme for International Student Assessment, the Progress in International Reading Literacy Study and the International Adult Literacy Survey. This contrasts with the standard approach which is to analyse just one survey in isolation. Second, we investigate whether results are sensitive to the choice of item response model that is used by survey organizers to aggregate respondents' answers into a single score. In both cases we focus on countries' average scores, the within-country differences in scores and on the association between the two.     

EMDR用于边缘型人格障碍的治疗

边缘型人格障碍(BPD)患者通常有显著的功能行使能力损害。其特征是冲动、情绪不稳、人际困难和身份认同问题,常常导致自杀行为和自杀姿态。虽然传统上认为BPD是一种慢性持久的障碍,但近期的研究却提示它可能会随着时间流逝而有所缓解,而且心理治疗可以促进缓解。BPD的病因与童年期虐待和不恰当的依恋关系有关。由于童年期虐待和创伤的重要意义,被公认有效的创伤治疗方法——眼动脱敏与再加工(EMDR)可能作为BPD的合理备选治疗方案之一。本文中的个案所获得的良好疗效阐明了EMDR在BPD治疗中的运用,提示有理由进行深入的对照研究。     

We Don't Need Your Help,But Will You Please Fix Our Children

A Bowen Family Systems therapist employs concepts of triangles and the family projection process to view a child's symptoms as embedded in the broader family patterns. This article will examine the dynamics of two family therapy cases where parents anxiously asked for their children's symptoms to be fixed. These cases will be used to explore the common presentation in child and adolescent mental health, where the parents are concerned for their children but are also keen not to open their own ‘can of worms’. The presenting problem in the first case was violent hostility between adolescent sisters and in the second case was an adolescent's anorexia. Drawing on client feedback, I reflect on the therapy process behind the divergent outcomes. In case one, the parents were willing to address their own troubled relationship and family of origin, while in case two, the parents discontinued therapy when family of origin dynamics began to be explored. The article suggests how the therapist can evoke parents' curiosity about their role in anxious family patterns, without them feeling blamed.     

Children’s Economic Well‐Being in Married and Cohabiting Parent Families

Increasingly, children are living with cohabiting parents. Prior work on the material well‐being of children living in cohabiting families is extended by including the biological relationship of children to adults, examining the racial and ethnic variations, and investigating the multiple indicators of material well‐being. We draw on the 1999 National Survey of America’s Families (N =34,509). Our findings suggest that children can potentially benefit from living with a cohabiting partner whose resources are shared with family members. Although children living with married rather than cohabiting parents fare better in terms of material well‐being, this advantage is accounted for by race and ethnic group and parents’ education. Marriage appears to provide more material advantages to White children than to Black or Latino children.     

CONTINUOUS-TIME FILTERS FOR STATE ESTIMATION FROM POINT PROCESS MODELS OF NEURAL DATA

Neural spike trains, the primary communication signals in the brain, can be accurately modeled as point processes. For many years, significant theoretical work has been done on the construction of exact and approximate filters for state estimation from point process observations in continuous-time. We have previously developed approximate filters for state estimation from point process observations in discrete-time and applied them in the study of neural systems. Here, we present a coherent framework for deriving continuous-time filters from their discrete-counterparts. We present an accessible derivation of the well-known unnormalized conditional density equation for state evolution, construct a new continuous-time filter based on a Gaussian approximation, and propose a method for assessing the validity of the approximation following an approach by Brockett and Clark. We apply these methods to the problem of reconstructing arm reaching movements from simulated neural spiking activity from the primary motor cortex. This work makes explicit the connections between adaptive point process filters for analyzing neural spiking activity in continuous-time, and standard continuous-time filters for state estimation from continuous and point process observations.
