Experimental investigation of shallow mixing layers at a river confluence using 3D-PTV

The present study investigates a simplified laboratory model of a river confluence (shallow mixing layer) using 3D-PTV to improve the understanding of the 3-D interaction between the large-scale turbulent motions (Kelvin-Helmholtz instability) and small-scale turbulent motions (Tollmien-Schlichting instability)

Brood patch and sex-ratio observations indicate breeding provenance and timing in New Zealand storm petrel (Fregetta maoriana)

We used measurements of brood patch and moult status to estimate the breeding phenology of New Zealand Storm-Petrel, using birds caught at sea within the Hauraki Gulf Marine Park near Auckland, New Zealand. Birds caught October–January had completely downy brood patches, whereas birds caught February–April had bare brood patches with an observed male bias in the February sex-ratio, consistent with a female pre-laying exodus typical of petrels and with the existence of an unknown colony in the region. No birds captured exhibited primary moult, which is known to occur in storm-petrels during their non-breeding season. Our data support the conclusion that the New Zealand storm-petrel breeds during January–June in northern New Zealand and that field surveys for the species on offshore islands in this region during this period are warrante

Leveraging Multimedia to Advance Science by Disseminating a Greater Variety of Scholarly Contributions in More Accessible Formats

For the welfare of the scientific community, we intentionally “rock the boat” about the way we conduct, recognize, and disseminate scholarly contributions. As a scientific community, we are doing ourselves a great disservice by ignoring the insights, artifacts, discoveries, and conversations that naturally occur in the scientific process of advancing knowledge that do not fit into the narrowly defined form of print-style papers. By failing to recognize, reward, and publish the wide variety of scholarly contributions that do not suit print-style papers, we hinder scientific progress, devalue important and necessary contributions to science, and demotivate these types of vital contributions. Although over three centuries of scientific publishing has demonstrated the effectiveness of the print medium for conveying scholarly knowledge, the print-style paper captures only a single form of scholarly contribution in a highly limited media format. Unfortunately, the current tenure and promotion process recognizes only this one form of scientific contribution. As a result, science at large advances inevitably only by this single type of contribution. Given the radical advances in audiovisual technologies, storage and bandwidth capacities, public virtual infrastructure, and global acceptance of user-generated open content, the time is ripe to exploit the possibility of publishing more forms of scholarly contributions in a publicly available multimedia format (e.g., video). In this paper, we examine the feasibility of this proposal, develop a model to demonstrate the sustainability of this approach, and discuss potential limitations

Acceptability of a Parental Early Warning Tool: Outcomes from a Feasibility Study of Parental Home Monitoring and Assessment

Aim: to explore the feasibility and acceptability of a Congenital Heart Assessment Tool (CHAT) as part of a home monitoring programme (HMP) for parents going home with their infant between stage 1 & 2 surgery for complex CHD. Background: HMPs were developed to encourage early recognition of deterioration in infants at risk of potentially life threatening events between stage 1 & 2. In this study, the HMP was compared with the CHAT, a traffic light system enabling assessment of the infant’s condition through individualised parameters. Method: A mixed methods approach including: data collected at four time points: at discharge [T0]; 2 weeks after [T1], 8 weeks after [T2] & after stage 2 surgery [T3] using self-report tools, interviews & daily diaries. Parents were recruited between August 2013 & February 2015 & randomised to either Gp A: HMP & CHAT; Gp B: CHAT or Gp C: standard discharge care. Results: 13 mothers, 4 fathers of 13 infants consented (A =5; B =4; C =4). The time period T0 to T3 ranged from 62-228 days; all infants survived stage 1 & 2 of surgery. The qualitative data set included 38 interviews. Four themes emerged regarding the CHAT: prepared parents for the signs to look for at home; easy to use; increased parental confidence & gave them reassurance to call for advice when something was different. Themes emerging regarding the HMP: parents felt daily wt. were not needed; the scales were ‘a hindrance more than helpful’, SpO2 was more reassuring. Gp C parents described normalisation of going home & recognition that the HMP may have made them more reliant & anxious. Only 2 diaries were completed; CHAT amber triggers (n=7 occasions, no admissions); red triggers & drop in SpO2 (n=1, 1 local hospital readmission); calls to ward staff (n=13); other contact with HCP (n=7) no contacts were cardiac in origin. Conclusions: The CHAT gave parents confidence regarding changes in their infant’s condition. No early admissions for stage 2 based on trigger of CHAT or HMP
