    Memory Recall: Cued or Free

    Get PDF
    Cues may be helpful to aid a person in memory recall. Two experiments were conducted in order to test the hypothesis that recall is enhanced with the presentation of cues. In Experiment 1, the recall performances for the same forty-eight participants were compared under cued and free recall conditions. A paired t-test was performed on the participants who received both cued and free recall questions. In Experiment 2, thirteen participants were given either cued only or free only questions to recall. An independent t-test was performed on the participants who received only cued recall questions or only free recall questions. There was a statistically significant finding that cues do help in recall compared to no cues being provided

    Live arts/arts alive : starcatchers research report 2011

    Get PDF
    Starcatchers is an innovative project which works in partnership with artists, arts venues child-care settings and families to experiment artistically with audiences of very young children, to encourage their participation and to develop exciting, inspiring performing arts experiences for children aged 0-4. Four artists in residence have worked for a year in a theatre venue in Scotland to engage children and families in a range of arts related performance experiences. Four accompanying researchers were each attached to one venue and have collaborated with the artists to observe children’s engagement, provide feedback, discuss ongoing work, and record the processes of project development. This report presents the findings from the analysis of the wide range of data collected and it suggests a number of conclusions and recommendations about developing the arts with very young children

    La mobilisation des connaissances en protection de l’enfance

    La protection de l’enfance est l’un des secteurs de services qui se développent le plus rapidement au Canada. Cependant, nous en savons étonnamment peu sur l’efficacité des services offerts aux enfants maltraités et négligés. Cet article examine de nouveaux modèles de mobilisation des connaissances conçus pour soutenir l’utilisation plus systématique de la recherche dans les services sociaux. Nous commençons par discuter des limites des modèles traditionnels de diffusion des connaissances. Ensuite, nous considérons certaines des recherches qui ont été faites sur les obstacles et les facteurs facilitant l’utilisation de la recherche en santé, en éducation et dans les services sociaux. Enfin, nous présentons un modèle de mobilisation des connaissances qui est mis à l’essai et évalué dans un organisme de protection de l’enfance au Québec, décrivons les processus locaux utilisés pour affiner les six indicateurs de résultats (récurrence de la maltraitance, retards scolaires, taux de placement, déplacements d’une ressource à une autre, durée des soins et participation d’un tribunal) et concluons en présentant un exemple d’un des indicateurs retenus.Child protection is one of the fastest growing services sectors in Canada, yet we know surprisingly little about the effectiveness of services for abused and neglected children. This article examines emerging knowledge mobilization models designed to support the more systematic use of research in social services. We start by discussing the limits of traditional knowledge dissemination models. We then consider some of the research that has been done on the barriers and facilitators of research utilization in health, education and social services. Finally, we present a knowledge mobilization model that is being pilot tested and evaluated in a child welfare agency in Quebec and describe the local processes used to refine six outcome indicators (recurrence of maltreatment ; school delay ; placement rate ; moves in care ; time in care ; and court involvement) and conclude by presenting an example of one of the selected indicators.La protección de la infancia es uno de los sectores de servicios de más rápido desarrollo en Canadá.

Discutimos, primero, los límites de los modelos tradicionales de la difusión de conocimientos.

    Intensity and Insight: Qualitative Longitudinal Methods as a Route to the Psycho-social

    Get PDF
    This working paper brings together papers presented at a symposium entitled Intensity and insight: qualitative longitudinal methods as a route into the psycho-social that was held as part of the conference Vital Signs: Researching Real Life, organised by the ESRC funded Realities node of the NCRM held at Manchester University on 9-11 September 2008. The aim of the symposium was to explore the value of QL methods as a tool for capturing the interplay of psychodynamic, social and historical dimensions of processual phenomona. We anticipated that contributors would address how hindsight, foresight and insight interact in the research process (Thomson and Holland 2003) and the ways in which researcher subjectivity becomes a central source of data and knowledge (Lucey et al. 2003). The symposium brought together three examples of current research into the formation and remaking of parenting identities, each of which employs a qualitative and longitudinal research design. Approaches to the generation of data included infant observation, repeat interviews, psychoanalytically informed field notes, photo-elicitation and the use of intergenerational research design. Methods of analysis included collaborative working and the use of groups in order to explore hidden meanings, researcher investments and alternative interpretations

    DNA methylation affects nuclear organization, histone modifications, and linker histone binding but not chromatin compaction

    Get PDF
    DNA methylation has been implicated in chromatin condensation and nuclear organization, especially at sites of constitutive heterochromatin. How this is mediated has not been clear. In this study, using mutant mouse embryonic stem cells completely lacking in DNA methylation, we show that DNA methylation affects nuclear organization and nucleosome structure but not chromatin compaction. In the absence of DNA methylation, there is increased nuclear clustering of pericentric heterochromatin and extensive changes in primary chromatin structure. Global levels of histone H3 methylation and acetylation are altered, and there is a decrease in the mobility of linker histones. However, the compaction of both bulk chromatin and heterochromatin, as assayed by nuclease digestion and sucrose gradient sedimentation, is unaltered by the loss of DNA methylation. This study shows how the complete loss of a major epigenetic mark can have an impact on unexpected levels of chromatin structure and nuclear organization and provides evidence for a novel link between DNA methylation and linker histones in the regulation of chromatin structure

    Genetic variation in the hypothalamic–pituitary–adrenal stress axis influences susceptibility to musculoskeletal pain: results from the EPIFUND study

    <b>Objectives</b> To determine if genetic variation in genes in the hypothalamic–pituitary–adrenal (HPA) axis, the primary stress response system, influences susceptibility to developing musculoskeletal pain.<p></p> <b>Methods</b> Pain and comorbidity data was collected at three time points in a prospective population-based cohort study. Pairwise tagging single nucleotide polymorphisms (SNPs) were selected and genotyped for seven genes. Genetic association analysis was carried out using zero-inflated negative binomial regression to test for association between SNPs and the maximum number of pain sites across the three time points in participants reporting pain, reported as proportional changes with 95% CIs. SNPs were also tested for association with chronic widespread pain (CWP) using logistic regression reporting odds ratios and 95% CI.<p></p> <b>Results</b> A total of 75 SNPs were successfully genotyped in 994 participants including 164 cases with persistent CWP and 172 pain-free controls. Multiple SNPs in SERPINA6 were associated with the maximum number of pain sites; for example, each copy of the T allele of rs941601 was associated with having 16% (proportional change=1.16, 95% CI 1.04 to 1.28, p=0.006) more pain sites compared to participants with the CC genotype. SERPINA6 gene SNPs were also associated with CWP. Significant associations between the maximum number of pain sites and SNPs in the CRHBP and POMC genes were also observed and a SNP in MC2R was also associated with CWP. Associations between SNPs and comorbidity of poor sleep quality and depression explained some of the associations observed.<p></p> <b>Conclusions</b> Genetic variation in HPA axis genes was associated with musculoskeletal pain; however, some of the associations were explained by comorbidities. Replication of these findings is required in independent cohorts
