Background: This research investigates the relationship between challenging parenting behaviour and childhood anxiety disorders proposed by Bögels and Phares (2008). Challenging parenting behaviour involves the playful encouragement of children to go beyond their own limits, and may decrease children’s risk for anxiety (Bögels & Phares, 2008). Method: Parents (n = 164 mothers, 144 fathers) of 164 children aged between 3.4 and 4.8 years participated in the current study. A multi-method, multi-informant assessment of anxiety was used, incorporating data from diagnostic interviews as well as questionnaire measures. Parents completed self-report measures of their parenting behaviour (n = 147 mothers, 138 fathers) and anxiety (n = 154 mothers, 143 fathers). Mothers reported on their child’s anxiety via questionnaire as well as diagnostic interview (n = 156 and 164 respectively). Of these children, 74 met criteria for an anxiety disorder and 90 did not. Results: Fathers engaged in challenging parenting behaviour more often than mothers. Both mothers’ and fathers’ challenging parenting behaviour was associated with lower report of child anxiety symptoms. However, only mothers’ challenging parenting behaviour was found to predict child clinical anxiety diagnosis. Limitations: Shared method variance from mothers confined the interpretation of these results. Moreover, due to study design, it is not possible to delineate cause and effect. Conclusions: The finding with respect to maternal challenging parenting behaviour was not anticipated, prompting replication of these results. Future research should investigate the role of challenging parenting behaviour by both caregivers as this may have implications for parenting interventions for anxious children.

This paper explores the unique approach to childhood and children’s literature of the research and teaching of the ‘Graduate Centre for International Research in Childhood: Literature, Culture, Media (CIRCL)’. CIRCL follows in its work the arguments of UK critical theorist Jacqueline Rose in her seminal 1984 book The case of Peter Pan or the impossibility of children’s fiction. Rose’s work has been widely and routinely referenced in Children’s Literature studies particularly, but CIRCL interprets her arguments as having quite different implications than those usually assumed. Rose is generally attributed with having pointed out that ‘childhood’ is not one, homogenous category, but that childhood is divided by gender, race, and ethnic, political and religious (and so on) identities. But for CIRCL this is only a first step in Rose’s arguments and certainly one not unique to her work anyway: the perception of various cultural and historical childhoods is widely held. Instead, my paper explores how Rose’s arguments are centrally about how ‘childhood’ itself cannot be maintained in the face of division, a division, moreover, which operates inevitably at every level, and which derives from Rose’s interpretation of psychoanalysis as formulated by Sigmund Freud, which Rose derives in turn from her readings of the interpretations of Freud by French analyst Jacques Lacan and French critical theorist Jacques Derrida. Finally, my paper argues how Rose’s position is about any ‘identity’, including gender and that this allies her work closely to that of the famous gender theorist Judith Butler, whose arguments are often (mis) understood in the same ways as those of Rose.

Cardiac myocyte hypertrophy is associated with an increase in expression of immediate early genes (e.g. c-jun) via activation of pre-existing transcription factors. The activity of CREB transcription factor is regulated through phosphorylation of Ser-133 by one of several protein kinases (e.g. protein kinase A (PKA), p90 ribosomal S6 kinases (RSKs) and the related kinase, MSK1). A cell-permeable form of cAMP, hypertrophic agonists (endothelin-1 (ET-1), phenylephrine (PE)) and hyperosmotic shock all promoted phosphorylation of CREB(Ser-133) in rat neonatal cardiac myocytes. The response to endothelin-1 required the extracellular signal-regulated kinase cascade which stimulates both RSKs and MSK1. Phosphorylation of CREB(Ser-133) in response to ET-1 was not associated with any increase in DNA binding to a consensus cAMP-response element (CRE). The rat c-jun promoter contains elements which may bind either c-Jun/ATF2 or CREB/ATF1 dimers. Using extracts from rat cardiac myocytes, we identified at least two complexes which bind to the most proximal of these elements, one of which contained CREB and the other c-Jun. Thus, phosphorylation and activation of CREB in cardiac myocytes may be effected by a range of different stimuli to influence the expression of immediate early genes such as c-jun.

Objectives Today, fractures at the growth plate (or physis) are common injuries in children, but provide challenges of identification in skeletonized remains. Clinical studies provide detailed information on the mechanisms, locations, age of occurrence, and complications associated with physeal fractures, enabling the development of new criteria for identifying this injury in non-adults. To test these criteria, skeletal remains from five rural and urban medieval cemeteries were examined. Methods The sample consisted of 961 skeletons (0-17 years) with open epiphyses. Macroscopic observation looked for any irregularities of the metaphysis or epiphysis which was consistent with the clinical appearance of physeal fractures or resulting complications. Radiographic examination was applied to identify fracture lines or early growth arrest. Results This study revealed 12 cases of physeal trauma (1.2%). Physeal fractures occurred predominantly at the distal end (75%), and while they were identified in all age categories, they were most frequent in those aged 12-17 years (0.2% TPR). The humerus was the most commonly affected location (3/12 or 25%). Conclusions This study highlights the potential for recognizing physeal fractures in children of all ages, enhancing our understanding of non-adult trauma, and enabling us to assign a more precise age of the injury to build up a picture of their activities in the past.
