Family touch practices and learning experiences in the museum

ABSTRACT

This paper investigates how family museum visitors crafted learning through interaction with one another and the touch objects of an exhibition. Through a case study of seven families’ interaction, we show how families used touch to bring their interests and resources into dialogue with museum expectations and resources. Using a multimodal approach to analyze observational data, we generate a fine-grained account of differently configured family touch practices and ways of experiencing and knowing objects through their material, sensory tactile and affective qualities. We conclude by highlighting how our findings can inform the design of touch exhibits to support family learning, with attention to engagement, narrative creation, and embodied learning, and point to the paper’s methodological contribution to the analysis of visitor situated real-time interaction and learning in museums.     

Covert social movement networks and the secrecy-efficiency trade off: The case of the UK suffragettes (1906–1914)

This paper formulates and empirically tests a number of hypotheses regarding the impact of covertness upon network structure. Specifically, hypotheses are deduced from theoretical arguments regarding a ‘secrecy-efficiency trade off’ which is said to shape covert networks. The paper draws upon data concerning the UK suffragettes. It is taken from a publicly archived UK Home Office document listing 1992 court appearances (for suffrage related activities), involving 1214 individuals and 394 court sessions, between 1906 and 1914. Network structure at earlier phases of suffragette activism, when the movement was less covert, is compared with that during the final phase, when it was more covert and meets the definitional criteria of what we call a ‘covert social movement network’ (CSMN). Support for the various hypotheses tested is variable but the key claims derived from the idea of the secrecy-efficiency trade off are supported. Specifically, the suffragettes’ network becomes less dense and less degree centralised as it becomes more covert.     

Optimizing the Quantity/Quality Trade-Off in Connectome Inference

We demonstrate a meaningful prospective power analysis for an (admittedly idealized) illustrative connectome inference task. Modeling neurons as vertices and synapses as edges in a simple random graph model, we optimize the trade-off between the number of (putative) edges identified and the accuracy of the edge identification procedure. We conclude that explicit analysis of the quantity/quality trade-off is imperative for optimal neuroscientific experimental design. In particular, identifying edges faster/more cheaply, but with more error, can yield superior inferential performance.     

Sponsor-Imposed Publication Restrictions Disclosed on ClinicalTrials.gov

We investigated whether sponsor-imposed publication restrictions for ClinicalTrials.gov trials were reasonable, based on consistency with Good Publication Practice 2 (GPP2). ClinicalTrials.gov trial record data were electronically imported (October 7, 2012) and screened for eligibility (phase 2–4, interventional, recruitment closed, results available, first received for registration after November 10, 2009, any sponsor type, investigators not sponsor employees). Two authors categorized restrictions information as consistent or not consistent with GPP2, resolving discrepancies by consensus. Of the eligible trials (388/484, n = 81,768 participants), 80.7% (313/388) had restrictions disclosed, and 92.5% (311/388) were industry-sponsored. Significantly more trials had restrictions that were consistent with GPP2 than not (74.1% [232/313], n = 55,280 participants vs. 25.9% [81/313], n = 19,677 participants; P < .001). Reasons for inconsistency were insufficient, unclear, or ambiguous information (48.1%, 39/81), sponsor-required approval for publication (35.8%, 29/81), sponsor-required text changes (8.6%, 7/81), and outright bans (7.4%, 6/81). Follow-up of trials with insufficient information and a contact email (response rate, 46.9% [15/32]) revealed 2 additional bans. A total of 776 participants had consented to trials that had publication bans. Many, but not all, sponsor-imposed publication restrictions disclosed on ClinicalTrials.gov may be considered reasonable. Sponsors should ensure restrictions are appropriately disclosed. Volunteers should be alerted to any restrictions before consenting to participate in a clinical trial.     

Beyond Absenteeism: Father Incarceration and Child Development

High rates of incarceration among American men, coupled with high rates of fatherhood among men in prison, have motivated recent research on the effects of parental imprisonment on children’s development. We use data from the Fragile Families and Child Wellbeing Study to examine the relationship between paternal incarceration and developmental outcomes for approximately 3,000 urban children. We estimate cross-sectional and longitudinal regression models that control not only for fathers’ basic demographic characteristics and a rich set of potential confounders, but also for several measures of pre-incarceration child development and family fixed effects. We find significant increases in aggressive behaviors and some evidence of increased attention problems among children whose fathers are incarcerated. The estimated effects of paternal incarceration are stronger than those of other forms of father absence, suggesting that children with incarcerated fathers may require specialized support from caretakers, teachers, and social service providers. The estimated effects are stronger for children who lived with their fathers prior to incarceration but are also significant for children of nonresident fathers, suggesting that incarceration places children at risk through family hardships including and beyond parent-child separation.     

From genes to societies

Research on model organisms has substantially advanced our understanding of aging. However, these studies collectively lack any examination of the element of sociality, an important feature of human biology. Social insects present a number of unique possibilities for investigating social influences on aging and potentially detecting new mechanisms for extremely prolonged, healthy life spans that have evolved naturally. Social evolution has led to life spans in reproductive females that are much longer (up to over 100-fold) than those of males or of nonreproductive worker castes. These differences are particularly dramatic because they are due to environmental influences, as all individuals develop from the same genomes. Social insect colonies consist of semi-autonomous individuals, and the relationship between the colony and the individual creates many interesting predictions in the light of the common theories of aging. Furthermore, the variety of lifestyles of social insects creates the potential for crucial comparative analyses across distinct social systems.     

Partnership Transitions and Maternal Parenting

We use data from the Fragile Families and Child Wellbeing Study (N = 1,975) to examine the association between mothers' partnership changes and parenting behavior during the first five years of their children's lives. We compare coresidential with dating transitions, and recent with more distal transitions. We also examine interactions between transitions and race/ethnicity, maternal education and family structure at birth. Findings indicate that both coresidential and dating transitions were associated with higher levels of maternal stress and harsh parenting; recent transitions had stronger associations than distal transitions. Maternal education significantly moderates these associations, with less educated mothers responding more negatively to instability in terms of maternal stress, and more educated mothers responding more negatively in terms of literacy activities.
