Constraints on nest site selection: a comparison of predator and flood avoidance in four species of marsh-nesting birds (genera: Catoptrophorus, Larus, Rallus, and Sterna)

Nest site characteristics associated with flood and predator avoidance were compared for four nonpasserine species of marsh-nesting birds: clapper rails, willets, laughing gulls, and common terns. Species with short nests, willets and terns, minimized flood damage by nesting on higher ground than did gulls and rails that build tall nests. Species with dispersed, cryptic nests had taller surrounding grass than did open-nesting colonial species. Total nest height was similar for species with tall nests and for terns whose short nests were elevated by placement on mats of dead Spartina grass. Willets had lower nest heights than the other species, probably because the inverse relation between grass height and ground height in the salt marsh makes it difficult for willets to find sites with high enough ground for flood avoidance while still retaining high enough grass for nest crypticity. Ground height for common terns and grass height for gulls and rails appear to be cues used in nest site selection. Nests of each species in which these characteristics were maximized were more successful in a major tidal flood. Laughing gulls and clapper rails appear to be more specialized salt marsh nesters than the other two species.     

Emotion Regulation in At‐Risk Preschoolers: Longitudinal Associations and Influences of Maternal Histories of Risk

Emotion regulation is a key challenge of early childhood. The present study examined emotion regulation behaviour longitudinally from infancy to preschool. The continuity of emotion regulation was explored within the larger ecological context of maternal childhood histories of aggression and social withdrawal and maternal use of constructive and non‐constructive behaviours. Forty‐five mothers with childhood histories of aggression or social withdrawal from the Concordia Longitudinal Risk Project, a prospective, longitudinal, intergenerational study, participated with their preschool children. Infants' emotion regulation behaviour was observed during interactions with their mothers when they were 5½ months of age. Emotion regulation in these same children as preschoolers was coded during an interference task using the Preschooler Self‐Regulatory Scheme. Longitudinal findings demonstrated continuity in children's use of emotion regulation behaviours from infancy to preschool. Higher maternal childhood histories of risk, specifically social withdrawal, contributed to the prediction of preschoolers' increased attention‐seeking behaviours. Mothers' use of non‐constructive verbalizations predicted more maladaptive styles of emotion regulation in their preschoolers. The findings highlight the importance of helping children develop adaptive emotion regulation skills from a young age and have implications for the design of preventive intervention programmes to help parents foster children's emotion regulation abilities.

Ethics in construction project briefing

The research reported in this paper set out to investigate ethics in the initial stages of construction projects. Briefing is the first real contact stage between the commissioner (client/employer) of a project — at this stage a potential project — and those involved in project realization — the designers and, subsequently, the constructors. It is well known that early decisions are of greatest impact and so, the importance of the initial contacts, communications and consequent decisions are paramount. Different project participants are known to pursue individual objectives to varying degrees as well as possessing different perspectives and perceptions and operating/behaving in different ways. Hence, determination of the appropriate form, content etc. of a project is, inevitably, a matter of exercising value judgements and compromises and so, involves ethical considerations. A case study of a project through the briefing stage is reported and analysed, from initial contacts to scheme approval. It is apparent that a number of ethical concerns are manifest through the various actions of the major participants. An earlier version of this paper was presented at the “Ethics and Social Responsibility in Engineering and Technology” meeting, New Orleans, 2003.     

Acceptability of,and Information Needs Regarding,Next-Generation Sequencing in People Tested for Hereditary Cancer: A Qualitative Study

Next generation sequencing (NGS) for patients at risk of hereditary cancer syndromes can also identify non-cancer related mutations, as well as variants of unknown significance. This study aimed to determine what benefits and shortcomings patients perceive in relation to NGS, as well as their interest and information preferences in regards to such testing. Eligible patients had previously received inconclusive results from clinical mutation testing for cancer susceptibility. Semi-structured telephone interviews were subjected to qualitative analysis guided by the approach developed by Miles and Huberman. The majority of the 19 participants reported they would be interested in panel/genomic testing. Advantages identified included that it would enable better preparation and allow implementation of individualized preventative strategies, with few disadvantages mentioned. Almost all participants said they would want all results, not just those related to their previous diagnosis. Participants felt that a face-to-face discussion supplemented by an information booklet would be the best way to convey information and achieve informed consent. All participants wanted their information stored and reviewed in accordance with new developments. Although the findings indicate strong interest among these individuals, it seems that the consent process, and the interpretation and communication of results will be areas that will require revision to meet the needs of patients.
