A Template Analysis of Intimate Partner Violence Survivors’ Experiences of Animal Maltreatment: Implications for Safety Planning and Intervention

This study explores the intersection of intimate partner violence (IPV) and animal cruelty in an ethnically diverse sample of 103 pet-owning IPV survivors recruited from community-based domestic violence programs. Template analysis revealed five themes: (a) Animal Maltreatment by Partner as a Tactic of Coercive Power and Control, (b) Animal Maltreatment by Partner as Discipline or Punishment of Pet, (c) Animal Maltreatment by Children, (d) Emotional and Psychological Impact of Animal Maltreatment Exposure, and (e) Pets as an Obstacle to Effective Safety Planning. Results demonstrate the potential impact of animal maltreatment exposure on women and child IPV survivors’ health and safety

Monitoring Striga asiatica (Orobanchaceae) seedbank for eradication success

To enable evaluation of eradication efforts for the parasitic plant Striga asiatica (L.) Kuntze, seed sachets were buried in perforated PVC canisters at 25 sites across the infested area in July 2016. The canister sites were selected based on the proximity to previous S. asiatica detections and cover the range of soil types and topographies associated within the eradication program treatment area. At each site the canisters received the same eradication treatments that were applied to the surrounding area. Site characteristics necessitated different combinations of false host (soybean), true host (corn), fumigant (dazomet), stimulant (ethylene) and herbicide treatments, to achieve a rapid decline in the soil seed bank. The viability of retrieved seeds shows an accelerated decline (92.5 % to 6.5 % in four years) across all sites in response to the treatments irrespective of treatment combination used. The viability of seeds was found to vary across sites, burial depth and time. The information collected has provided valuable data for the eradication of S. asiatica in Australia and for evaluating the timing for release of paddocks from active treatment

Information Requirements for Supervisory Air Traffic Controllers in Support of a Wake Vortex Departure System

Closely Space Parallel Runway (CSPR) configurations are capacity limited for departures due to the requirement to apply wake vortex separation standards from traffic departing on the adjacent parallel runway. To mitigate the effects of this constraint, a concept focusing on wind dependent departure operations has been developed, known as the Wake Turbulence Mitigation for Departures (WTMD). This concept takes advantage of the fact that crosswinds of sufficient velocity blow wakes generated by aircraft departing from the downwind runway away from the upwind runway. Consequently, under certain conditions, wake separations on the upwind runway would not be required based on wakes generated by aircraft on the downwind runway, as is currently the case. It follows that information requirements, and sources for this information, would need to be determined for airport traffic control tower (ATCT) supervisory personnel who would be charged with decisions regarding use of the procedure. To determine the information requirements, data were collected from ATCT supervisors and controller-in-charge qualified individuals at Lambert-St. Louis International Airport (STL) and George Bush Houston Intercontinental Airport (IAH). STL and IAH were chosen as data collection sites based on the implementation of a WTMD prototype system, operating in shadow mode, at these locations. The 17 total subjects (STL: 5, IAH: 12) represented a broad-base of air traffic experience. Results indicated that the following information was required to support the conduct of WTMD operations: current and forecast weather information, current and forecast traffic demand and traffic flow restrictions, and WTMD System status information and alerting. Subjects further indicated that the requisite information is currently available in the tower cab with the exception of the WTMD status and alerting. Subjects were given a demonstration of a display supporting the prototype systems and unanimously stated that the WTMD status information they felt important was represented. Overwhelmingly, subjects felt that approving, monitoring and terminating the WTMD procedure could be integrated into their supervisory workload

Bridging the Gap:Parent and Child Perspectives of Living With Cerebral Visual Impairments

Cerebral Visual Impairment (CVI) is an umbrella term which includes abnormalities in visual acuity, or contrast sensitivity or colour; ocular motility; visual field and the conscious and unconscious filtering or processing of visual input. Children with CVI have specific needs and problems relating to their development from infancy to adulthood which can impact on their wellbeing. Recent research indicates the complexities of living with CVI but there remains limited information of the full impact of CVI on families’ everyday lives. The qualitative interviews reported here explored families’ experiences to discover the impact of CVI on all aspects of everyday life. Parents and children (aged 6–18) were invited to participate in semi-structured interviews, either face to face, by phone or video call between January 2018 and February 2019. Topics covered everyday practicalities of living with CVI, focusing on challenges and what worked well at school and home. Interviews were audio-recorded and subject to thematic analysis to look for patterns across the data. Twenty families took part in interviews, with eight children/young people within those families contributing interviews of their own. Four themes were developed from the interviews: (1) Assessment and understanding implications of CVI, (2) Education, (3) Family life, (4) Psychological wellbeing and quality of life. The interviews provide valuable insights into the impact of living with CVI and highlight the need for more awareness of the condition among professionals in both health and education settings

Climate sensitivity from both physical and carbon cycle feedbacks

The surface warming response to anthropogenic forcing is highly sensitive to the strength of feedbacks in both the physical climate and carbon cycle systems. However, the definitions of climate feedback, λClimate in W·m−2·K−1, and climate sensitivity, SClimate in K/(W/m2), explicitly exclude the impact of carbon cycle feedbacks. Here we provide a new framework to incorporate carbon feedback into the definitions of climate feedback and sensitivity. Applying our framework to the Global Carbon Budget reconstructions reveals a present‐day terrestrial carbon feedback of λCarbon = 0.31 ± 0.09 W·m−2·K−1 and an ocean carbon feedback of −0.06 to 0.015 W·m−2·K−1 in Earth system models. Observational constraints reveal a combined climate and carbon feedback of λClimate+Carbon = 1.48 W·m−2·K−1 with a 95% range of 0.76 to 2.32 W·m−2·K−1 on centennial time scales, corresponding to a combined climate and carbon sensitivity of SClimate+Carbon = 0.67 K/(W/m2) with a 95% range of 0.43 to 1.32 K/(W/m2)

What matters to people and families affected by cerebral small vessel disease (SVD)?:A qualitative grounded theory investigation

BACKGROUND: Cerebral small vessel disease (SVD) is a common neurological disorder contributing to stroke, dementia, and disability. No treatment options exist although clinical trials are ongoing. We aimed to understand what matters to people and families affected by SVD to inform future research.METHODS: We thematically analysed unsolicited correspondences from members of the public addressed to members of the Edinburgh SVD Research Group on a variety of subjects related to SVD. We used inductive thematic codes, categorised under concerns, requests, emotions, and contributions, to form a grounded theory that categorised and ranked concerns raised.RESULTS: 101 correspondents expressed 346 concerns between August 2015 and February 2021, mostly via email. 60 correspondents (59.4 %) disclosed a SVD diagnosis, 39 (38.6 %) disclosed a previous stroke or TIA, and 40 (39.6 %) were family of people living with SVD. Primary concerns related to cognitive problems (number of correspondents (n)=43 (42.6 %)), lack of support or information from healthcare services ( n = 41 (40.6 %)), prognosis ( n = 37 (36.6 %)), sensory disturbances ( n = 27 (26.7 %)), functional problems ( n = 24, (23.8 %)), impact on daily life ( n = 24 (23.8 %)), and causes of SVD ( n = 19 (18.8 %)). 57 correspondents (56.4 %) expressed support for research, 43 (42.6 %) expressed an eagerness to understand SVD, 35 (34.7 %) expressed helplessness, and 19 (18.8 %) expressed frustration. CONCLUSIONS: Cognitive decline was the main concern for people and families living with SVD who corresponded with the Edinburgh SVD research group. These findings also indicate a need for more accessible services and better information about SVD for patients and families.</p

Adhesion to Vitronectin and Collagen I Promotes Osteogenic Differentiation of Human Mesenchymal Stem Cells

The mechanisms controlling human mesenchymal stem cells (hMSC) differentiation are not entirely understood. We hypothesized that the contact with extracellular matrix (ECM) proteins normally found in bone marrow would promote osteogenic differentiation of hMSC in vitro. To test this hypothesis, we cultured hMSC on purified ECM proteins in the presence or absence of soluble osteogenic supplements, and assayed for the presence of well-established differentiation markers (production of mineralized matrix, osteopontin, osteocalcin, collagen I, and alkaline phosphatase expression) over a 16-day time course. We found that hMSC adhere to ECM proteins with varying affinity ([Formula: see text]) and through distinct integrin receptors. Importantly, the greatest osteogenic differentiation occurred in cells plated on vitronectin and collagen I and almost no differentiation took place on fibronectin or uncoated plates. We conclude that the contact with vitronectin and collagen I promotes the osteogenic differentiation of hMSC, and that ECM contact alone may be sufficient to induce differentiation in these cells

Islet autoantibody profiles associated with higher diabetes risk in Lithuanian compared with English schoolchildren

Over a 15 year period, the incidence of type 1 diabetes has doubled in Lithuania, whilst increasing by a third in England, however England still has the higher incidence. Analysis of sera collected from non-diabetic schoolchildren from Lithuania and England more than 20 years ago showed a similar number of multiple autoantibody positive schoolchildren between the populations, but a higher prevalence of islet antigen-2 autoantibodies (IA-2A) in English schoolchildren. We aimed to use recently developed, more specific islet autoantibody tests, to characterise differences in humoral autoimmunity between these two general population cohorts in greater detail. Samples from 88 Lithuanian and 133 English schoolchildren previously found islet autoantibody positive were selected for measurement of additional islet autoantibodies by radioimmunoassay. Samples were tested for autoantibodies to zinc transporter 8 (ZnT8A), GAD(96-585), the protein tyrosine phosphatase region of islet antigen-2 (PTPA), and the related IA-2βA while autoantibodies to IA-2A were re-assayed using the current harmonized method. IA-2 related autoantibodies PTPA (0.13% vs. 0.45%, p=0.027) and IA-2βA (0% vs. 0.35%, p<0.001), but not IA-2A measured using the harmonized method, were less common in Lithuanian compared to English schoolchildren. Lithuanian schoolchildren who were islet autoantibody positive, were positive for fewer biochemical autoantibodies compared with English schoolchildren (p=0.043). Background rates of islet autoimmunity in childhood differ subtly between countries which have different incidences of type 1 diabetes. The optimal screening strategy (age and combination of markers) for detection of islet autoimmunity may vary between countries dependent on the pattern of autoantibodies found in the general population
