Madagascar corals track sea surface temperature variability in the Agulhas Current core region over the past 334 years

The Agulhas Current (AC) is the strongest western boundary current in the Southern Hemisphere and is key for weather and climate patterns, both regionally and globally. Its heat transfer into both the midlatitude South Indian Ocean and South Atlantic is of global significance. A new composite coral record (Ifaty and Tulear massive Porites corals), is linked to historical AC sea surface temperature (SST) instrumental data, showing robust correlations. The composite coral SST data start in 1660 and comprise 200 years more than the AC instrumental record. Numerical modelling exhibits that this new coral derived SST record is representative for the wider core region of the AC. AC SSTs variabilities show distinct cooling through the Little Ice Age and warming during the late 18th, 19th and 20th century, with significant decadal variability superimposed. Furthermore, the AC SSTs are teleconnected with the broad southern Indian and Atlantic Oceans, showing that the AC system is pivotal for inter-ocean heat exchange south of Africa

So round the spiral again: a reflective participatory research project with children and young people

Historically the voices of children in research have been silent. They are often seen as victims or beneficiaries of research rather than co-researchers or partners. This is beginning to change with rowing awareness that involving children in the design, delivery and evaluation of services can make services more accessible to them and their peers. This article reviews the processes involved n a research project commissioned by Children’s Fund, which investigated the use and non-use of services within a local area. The involvement of children was paramount and resulted in the recruitment f nine young researchers between the ages of 7–13. Various cycles of participatory action research evolved throughout the project and this article focuses specifically on two—recruiting the researcher and training young researchers. We consider the cycles of reflection and action crucial to any participatory project and discuss how lessons were learned to inform further stages of the process. Themes such as challenges, power and participation are discussed throughout

Incidents during out-of-hospital patient transportation

Publisher's copy made available with the permission of the publisher © Australian Society of AnaesthetistsOut-of-hospital patient transportation (retrieval) of critically ill patients occurs within highly complex environments. Adverse events are not uncommon. Incident monitoring provides a means to better understand such events. The aim of this study was to characterize incidents occurring during retrieval to provide a basis for developing corrective strategies. Four organizations contributed 125 reports, documenting 272 incidents; 91% of forms documented incidents as preventable. Incidents related to equipment (37%), patient care (26%), transport operations (11%), interpersonal communication (9%), planning or preparation (9%), retrieval staff (7%) and tasking (2%). Incidents occurred during patient transport to the receiving facility (26%), at patient origin (26%), during patient loading (20%), at the retrieval service base (18%) and receiving facility (9%). Contributing factors were system-based for 54% and human-based for 42%. Haste (7.5%), equipment malfunctioning (7.2%) or missing (5.5%), failure to check (5.8%) and pressure to proceed (5.2%) were the most frequent contributing factors. Harm was documented in 59% of incidents with one death. Minimizing factors were good crew skills/teamwork (42%), checking equipment (17%) and patient (8%), patient monitors (15%), good luck (14%) and good interpersonal communication (4%). Incident monitoring provides sufficient insight into retrieval incidents to be a useful quality improvement tool for retrieval services. Information gathered suggested improvements in retrieval equipment design and use of alternative power sources, the use of pro formae for equipment checking, patient assessment, preparation for transportation and information transfer. Lessons from incidents in other areas applicable to retrieval should be linked for analysis with retrieval incidents.A. Flabouris, W. B. Runciman, B.

The Safety Attitudes Questionnaire: psychometric properties, benchmarking data, and emerging research

BACKGROUND: There is widespread interest in measuring healthcare provider attitudes about issues relevant to patient safety (often called safety climate or safety culture). Here we report the psychometric properties, establish benchmarking data, and discuss emerging areas of research with the University of Texas Safety Attitudes Questionnaire. METHODS: Six cross-sectional surveys of health care providers (n = 10,843) in 203 clinical areas (including critical care units, operating rooms, inpatient settings, and ambulatory clinics) in three countries (USA, UK, New Zealand). Multilevel factor analyses yielded results at the clinical area level and the respondent nested within clinical area level. We report scale reliability, floor/ceiling effects, item factor loadings, inter-factor correlations, and percentage of respondents who agree with each item and scale. RESULTS: A six factor model of provider attitudes fit to the data at both the clinical area and respondent nested within clinical area levels. The factors were: Teamwork Climate, Safety Climate, Perceptions of Management, Job Satisfaction, Working Conditions, and Stress Recognition. Scale reliability was 0.9. Provider attitudes varied greatly both within and among organizations. Results are presented to allow benchmarking among organizations and emerging research is discussed. CONCLUSION: The Safety Attitudes Questionnaire demonstrated good psychometric properties. Healthcare organizations can use the survey to measure caregiver attitudes about six patient safety-related domains, to compare themselves with other organizations, to prompt interventions to improve safety attitudes and to measure the effectiveness of these interventions

Climate variability affects water-energy-food infrastructure performance in East Africa

The need to assess major infrastructure performance under a changing climate is widely recognized yet rarely practiced, particularly in rapidly growing African economies. Here, we consider high-stakes investments across the water, energy, and food sectors for two major river basins in a climate transition zone in Africa. We integrate detailed interpretation of observed and modeled climate-system behavior with hydrological modeling and decision-relevant performance metrics. For the Rufiji River in Tanzania, projected risks for the mid-21st century are similar to those of the present day, but for the Lake Malawi-Shire River, future risk exceeds that experienced during the 20th century. In both basins a repeat of an early-20th century multi-year drought would challenge the viability of proposed infrastructure. A long view, which emphasizes past and future changes in variability, set within a broader context of climate-information interpretation and decision making, is crucial for screening the risk to infrastructure

Safety climate factors in construction – a literature review

It is an established fact that a mature safety climate and a rich safety culture contribute to achieving a safe workplace. This paper aims to explore and to make explicit the existing safety climate assessment tools and dimensions and suggests the leading factors that can be used for safety climate assessment in construction. The construction industry and the status of occupational safety and health are firstly discussed in a global context. The concept of safety climate is then discussed with a review of different safety climate factors from the published literature. A qualitative research method was employed to explore the existing safety climate factors. A total of 19 safety climate assessment tools with 103 safety climate factors spanning over a period of 39 years (1980–2019) are discussed. The most prevailing safety climate factors including management commitment, training, employees’ involvement, behaviour, communication, accountability and justice, and leadership are discussed in the paper. It is recommended that the factors discussed in this paper may need to be validated first before they are incorporated in the assessment of the safety climate of a specific construction project and organisation in a country or region

Relationships between motion after-effects motion sickness susceptibility and "receptivity".

Initially, this thesis constituted an attempt to identify, within the spiral after-effect phenomenon (SAE), the primary source of the wide and reliable individual differences observed in reporting its persistence under constant stimulus conditions. However, as indicated by the title, the pursuit of this aim involved expanding its scope to include stable inter-personal, variation in other spheres, namely labyrinthine after-effects, motion sickness susceptibility, and estimations of sensory magnitude. Experimental evidence, assembled in the body of the thesis, suggested that individual differences in sae persistence, and those observed in these other, apparently disparate activities, emanate from the same underlying source: idiosyncratic differences in the extent to which stimulus. Energy is transduced by the central nervous system. This notion emerged, finally, as the "receptivity" of the title. The existence of a stable dimension of individual differences in sensory function was postulated, the extreme positions of which were labelled: 'receptive' and 'nonreceptive'.'Receptives' were characterised by relatively persistent after-sensations and steep sae/induction period slope values, relatively steep magnitude functions for intensive sensory continua, and a fairly high incidence of reported motion sickness. 'Nonreceptives' showed the opposite characteristics

Intention to commit driving violations: An application of the theory of planned behavior

This study assessed the ability of the theory of planned behavior (TPB) to account for drivers' intentions to commit four specific driving violations: drinking and driving, speeding, close following, and overtaking in risky circumstances. A stratified sample of drivers (N = 881) was surveyed with a questionnaire constructed to measure attitudes toward behaviors, subjective norms, perceived behavioral control, and behavioral intentions, the key constructs in TPB. Results showed that the addition of perceived behavioral control led to significant increments in the amount of explained variance in intentions, thereby supporting the theory The relation between subjective norms and behavioral intentions was consistently stronger than that between attitudes toward behaviors and behavioral intentions. Analyses of variance differentiated demographic subgroups of drivers in terms of behavioral beliefs, outcome evaluations, normative beliefs, motivation to comply, and control beliefs

Perceived consensus in estimates of the prevalence of driving errors and violations

This paper reports a study of perceptions of the prevalence of certain driving errors and violations in a large (N= 1,656) sample of drivers. In keeping with previous research on perceptions of social consensus, it was predicted that (a) drivers who reported that they themselves regularly commit these errors and violations would make larger estimates of the percentage of other road users who regularly engage in these behaviors, by comparison with drivers who reported that they do not regularly commit these errors and violations; (b) comparison of estimates of social consensus for own behavior with the actual numbers of respondents reporting that they did or did not engage in these behaviors would show that those who do commit the behaviors regularly would overestimate consensus for their position, while those who do not commit the behaviors regularly would underestimate consensus for their position; and (c) these tendencies to overestimate or underestimate actual consensus for own position would be correlated with the perceived offensiveness to others of the behavior concerned, such that departures from actual consensus would be greater for behaviors rated as more offensive. The results provide strong support for the first two predictions but none for the third; indeed, the degree of over- or underestimation tended to be inversely related to offensiveness. In addition, there were unanticipated but highly consistent sex and age differences in perceptions of the prevalence of the target behaviors, with female and younger respondents making higher estimates than male and older respondents, respectively. The theoretical and practical implications of these findings are discussed
