Assessing communicative intents in maltreated toddlers

There is evidence that maltreated school-aged children have an elevated incidence of expressive language delay, which is often attributed to the cumulative effects of maltreatment. Younger children and toddlers do not consistently demonstrate this delay. There is some ambiguity whether language delays can be observed in toddlers since language is not well developed at this age. However, if gestural communication is also studied as part of language development, a broader sample of behavior becomes available. Intentional communication includes the use of words and gestures to express a child\u27s intent or desire. Examining maltreated toddlers\u27 intentional communication provides an opportunity to study how language develops under less than optimal conditions. This study examines communicative intents in maltreated and nonmaltreated toddlers (ages 22 to 31 months) and the caregiving interactions of their mothers. The sample is composed of thirty-nine mother-toddler dyads from a Mid-Western city. Maternal maltreatment was documented on thirteen lower class toddlers, who were matched on sex, age, race and SES. Ten middle class dyads composed another comparison group. The lower class toddlers were given the Bayley Scales of Infant Development (BSID) as part of a larger study. Videotapes of a play session between mother-toddler dyads were coded using The Parent/Caregiver Interaction Scale to rate maternal behaviors plus two child communication inventories to code Intentional Communication and Negotiation of Failed Messages. Competency scores were computed for all toddlers on Intentional Communication and Developmental Competence was compared on the lower class toddlers. Two scores compared maternal appropriateness to toddler reactivity and communication competence. Results showed that maltreatment was not related to child Intentional Communication, except that maltreated toddlers acknowledged their mothers\u27 messages more frequently. Social class accounted for differences on most maternal and some toddler variables. Developmental Competence accounted for significant differences in lower class toddlers\u27 Intentional Communication and Social Competence. Patterns of high maternal verbal interaction and control over child\u27s activities were related to toddler\u27s competence in Intentional Communication, suggesting that mothers who are more verbal and appropriate in their control have more competent toddlers

“Like you, I want to feel excitement and hope about our city”: ‘Christchurch the city’ in campaign material of the 2013 Christchurch City Council election

The Christchurch City Council election of 2013 provides a compelling case study through which to consider the interaction between politics and city space. On the one hand, through the careful placement of campaign posters, politics encroached on the physical terrain of the city. On the other hand, candidates included in their campaign material multitudinous references to ‘Christchurch the city,’ demonstrating the extent to which the physical environment of the post-disaster city had become central to local politics

Pediatric sleep-related breathing disorders: advances in imaging and computational modeling

We understand now that sleep of sufficient length and quality is required for good health. This is particularly true for infants and children, who have the added physiologic task of growth and development, as compared to their adult counterparts. Sleep-related breathing disorders (SRBDs) are common in childhood and if unrecognized and not treated can result in significant morbidity. For example, children with obstructive sleep apnea (OSA) can exhibit behavioral, mood, and learning difficulties. If left untreated, alterations in the function of the autonomic nervous system and a chronic inflammatory state result, contributing to the risk of heart disease, stroke, glucose intolerance, and hypertension in adulthood

Genetic Indicators of Drug Resistance in the Highly Repetitive Genome of Trichomonas vaginalis

Trichomonas vaginalis, the most common nonviral sexually transmitted parasite, causes ∼283 million trichomoniasis infections annually and is associated with pregnancy complications and increased risk of HIV-1 acquisition. The antimicrobial drug metronidazole is used for treatment, but in a fraction of clinical cases, the parasites can become resistant to this drug. We undertook sequencing of multiple clinical isolates and lab derived lines to identify genetic markers and mechanisms of metronidazole resistance. Reduced representation genome sequencing of ∼100 T. vaginalis clinical isolates identified 3,923 SNP markers and presence of a bipartite population structure. Linkage disequilibrium was found to decay rapidly, suggesting genome-wide recombination and the feasibility of genetic association studies in the parasite. We identified 72 SNPs associated with metronidazole resistance, and a comparison of SNPs within several lab-derived resistant lines revealed an overlap with the clinically resistant isolates. We identified SNPs in genes for which no function has yet been assigned, as well as in functionally-characterized genes relevant to drug resistance (e.g., pyruvate:ferredoxin oxidoreductase). Transcription profiles of resistant strains showed common changes in genes involved in drug activation (e.g., flavin reductase), accumulation (e.g., multidrug resistance pump), and detoxification (e.g., nitroreductase). Finally, we identified convergent genetic changes in lab-derived resistant lines of Tritrichomonas foetus, a distantly related species that causes venereal disease in cattle. Shared genetic changes within and between T. vaginalis and Tr. foetus parasites suggest conservation of the pathways through which adaptation has occurred. These findings extend our knowledge of drug resistance in the parasite, providing a panel of markers that can be used as a diagnostic tool

Supporting Spartina: Interdisciplinary perspective shows Spartina as a distinct solid genus

In 2014 a DNA-based phylogenetic study confirming the paraphyly of the grass subtribe Sporobolinae proposed the creation of a large monophyletic genus Sporobolus, including (among others) species previously included in the genera Spartina, Calamovilfa, and Sporobolus. Spartina species have contributed substantially (and continue contributing) to our knowledge in multiple disciplines, including ecology, evolutionary biology, molecular biology, biogeography, experimental ecology, environmental management, restoration ecology, history, economics, and sociology. There is no rationale so compelling to subsume the name Spartina as a subgenus that could rival the striking, global iconic history and use of the name Spartina for over 200 years. We do not agree with the arguments underlying the proposal to change Spartina to Sporobolus. We understand the importance of taxonomy and of formalized nomenclature and hope that by opening this debate we will encourage positive feedback that will strengthen taxonomic decisions with an interdisciplinary perspective. We consider the strongly distinct, monophyletic clade Spartina should simply and efficiently be treated as the genus Spartina

Share an Idea, spare a thought: Community consultation in Christchurch’s time-bound post-earthquake rebuild

The Canterbury Earthquake Recovery Act 2011 (CER Act), brought into effect after the 22 February 2011 earthquake which devastated the city of Christchurch, New Zealand, outlines as its second purpose the imperative ‘to enable community participation in the planning of the recovery of affected communities without impeding a focused, timely, and expedited recovery.’ The Act thus clearly highlights the importance of community participation and a time-bound recovery process. Viewing the fundamental disconnect between these two aims through the lens of community consultation, this article demonstrates that the necessity of a timely recovery works against the generation of meaningful community participation, providing an insight into the strain placed on democratic processes and questioning whether the social right to housing and the political right to opinion can both be adequately met during times of difficulty engendered by natural disaster

An inventory of community-led and non-governmental organisations and initiatives in post-earthquake Canterbury (to September 2013)

The impact of the Canterbury earthquake sequence of 2010-12 and its aftermath has been enormous. This inventory lists some of the thousands of community-led groups and initiatives across the region that have developed or evolved as a result of the quake. This inventory is the third such inventory to have been produced. The Christchurch Earthquake Activity Inventory was released by Landcare Research in May 2011, three months after the devastating 22 February 2011 earthquake. The second inventory, entitled An Inventory of Community-led Recovery Initiatives in Canterbury, was collated by Bailey Peryman and Dr Suzanne Vallance (Lincoln University) approximately one year after the February earthquake. The research for this third inventory was undertaken over a four month period from June to September 2013, and was conducted primarily through online searches.This research was undertaken with funding support from the Natural Hazards Platform and GNS, New Zealand
