Closing the gap? Overcoming limitations in sociomaterial accounts of early literacy
This article uses a sociomaterial perspective to explore how deficit views of young childrenās language and literacy are sustained and can be challenged. Foregrounding the notion of multiplicity, it considers how diverse sociomaterial relations work to uphold particular kinds of practice and particular arrangements of bodies and things over others. These relations may interfere with and interface with each other in different ways, sometimes sustaining but also potentially disrupting deficit discourses and practices. Our sociomaterial perspective is illustrated with a short vignette from a study of children and touchscreen tablets in an early years setting. An initial analysis is followed by a series of alternate and tentative tracings of other kinds of relations that play through those moments. The article contributes to debates about social inequality by troubling the certainties generated though deficit models of childrenās literacy, whilst working proactively to envision and produce alternate possibilities that foreground the potentialities generated as people and other materials assemble together
Reclaiming social work? an evaluation of systemic units as an approach to delivering childrenās services
This report presents the findings of an evaluation of the systemic unit model as an approach to the delivery of Childrenās Social Services. The systemic unit model has sometimes been referred to as the āHackney Modelā or āReclaiming Social Workā (Cross et al, 2010; Munro, 2011a; Trowler and Goodman, 2012). The evaluation is an in-depth comparative description of practice and the factors shaping it in three local authorities. One of the authorities used the systemic unit model; the other two authorities differed but both had a more conventional model for the structure of services. This involved individual allocation to social workers who received supervision from a line manager
The Effect of Shift Structure on Performance
The effect of shift structure on worker performance and productivity is of increasing interest to firms and regulatory bodies. Using approximately 743,000 emergency medical incidents attended by 2,381 paramedics in Mississippi, we evaluate the extent that paramedics\u27 performance toward the end of shifts is impacted by shift length. We find evidence that performance deteriorates toward the end of long shifts, and argue that fatigue is the mediating factor. Our calculations imply that such deterioration may result in a 0.76 percent increase in 30-day mortality. These findings have implications for workforce organization, calling attention to regulation designed to limit extended work hours
Couplesā dyadic coping in the context of child-related stressors: A systematic review across three decades
The relevance of dyadic coping (DC), a concept how couples cope with stressors together, has been established in different contexts (e.g., daily hassles, mental and physical health) and is related to different outcomes such as relationship satisfaction, relationship quality and stability, psychological well-being, and child behavior. The current systematic review aims at providing an integration of the field of research on coupleās DC with child-related stressors which are understood as demands that arise for couples due to becoming or being parents. DC and related search terms were used for the literature search in PsycINFO, Psyndex, and Medline. We included 55 publications (reporting empirical data on 6,779 couples in total) including quantitative, qualitative, and mixed-methods studies published between 1990 and 2020. We applied a narrative synthesis approach organizing the results around six identified areas of child-related stressors: pregnancy and transition to parenthood, parenting, child mental health, child disability, child chronic physical illness, and child death. Overall, results show the importance of DC for both individual and relationship functioning in the context of child-related stress. Surprisingly, effects of parental DC on child outcomes remained understudied, although the existing studies yield promising results for child adjustment. In conclusion, adapting a āweā-perspective, mutual understanding and support is of importance not only to overcome the stressor but also to grow together as a couple. As DC plays a significant role for couples to cope in a resilient way when facing child-related stressors it should be more promoted in couple- and family counseling and therapy
Limiting the effects of earthquakes on gravitational-wave interferometers
Ground-based gravitational wave interferometers such as the Laser
Interferometer Gravitational-wave Observatory (LIGO) are susceptible to
high-magnitude teleseismic events, which can interrupt their operation in
science mode and significantly reduce the duty cycle. It can take several hours
for a detector to stabilize enough to return to its nominal state for
scientific observations. The down time can be reduced if advance warning of
impending shaking is received and the impact is suppressed in the isolation
system with the goal of maintaining stable operation even at the expense of
increased instrumental noise. Here we describe an early warning system for
modern gravitational-wave observatories. The system relies on near real-time
earthquake alerts provided by the U.S. Geological Survey (USGS) and the
National Oceanic and Atmospheric Administration (NOAA). Hypocenter and
magnitude information is generally available in 5 to 20 minutes of a
significant earthquake depending on its magnitude and location. The alerts are
used to estimate arrival times and ground velocities at the gravitational-wave
detectors. In general, 90\% of the predictions for ground-motion amplitude are
within a factor of 5 of measured values. The error in both arrival time and
ground-motion prediction introduced by using preliminary, rather than final,
hypocenter and magnitude information is minimal. By using a machine learning
algorithm, we develop a prediction model that calculates the probability that a
given earthquake will prevent a detector from taking data. Our initial results
indicate that by using detector control configuration changes, we could prevent
interruption of operation from 40-100 earthquake events in a 6-month
time-period
Accuracy of Emergency Medical Services Dispatcher and Crew Diagnosis of Stroke in Clinical Practice.
BACKGROUND: Accurate recognition of stroke symptoms by Emergency Medical Services (EMS) is necessary for timely care of acute stroke patients. We assessed the accuracy of stroke diagnosis by EMS in clinical practice in a major US city.
METHODS AND RESULTS: Philadelphia Fire Department data were merged with data from a single comprehensive stroke center to identify patients diagnosed with stroke or TIA from 9/2009 to 10/2012. Sensitivity and positive predictive value (PPV) were calculated. Multivariable logistic regression identified variables associated with correct EMS diagnosis. There were 709 total cases, with 400 having a discharge diagnosis of stroke or TIA. EMS crew sensitivity was 57.5% and PPV was 69.1%. EMS crew identified 80.2% of strokes with National Institutes of Health Stroke Scale (NIHSS) ā„5 and symptom durationmodel, correct EMS crew diagnosis was positively associated with NIHSS (NIHSS 5-9, OR 2.62, 95% CI 1.41-4.89; NIHSS ā„10, OR 4.56, 95% CI 2.29-9.09) and weakness (OR 2.28, 95% CI 1.35-3.85), and negatively associated with symptom duration \u3e270āmin (OR 0.41, 95% CI 0.25-0.68). EMS dispatchers identified 90 stroke cases that the EMS crew missed. EMS dispatcher or crew identified stroke with sensitivity of 80% and PPV of 50.9%, and EMS dispatcher or crew identified 90.5% of patients with NIHSS ā„5 and symptom duration \u3c6 \u3eh.
CONCLUSION: Prehospital diagnosis of stroke has limited sensitivity, resulting in a high proportion of missed stroke cases. Dispatchers identified many strokes that EMS crews did not. Incorporating EMS dispatcher impression into regional protocols may maximize the effectiveness of hospital destination selection and pre-notification
Dyadic coping and mental health in couples: A systematic review
Globally, one out of three people suffer from a mental health issue during their lifetime. In romantic relationships, impaired mental health does not only affect the individual but also their partner and therefore needs to be coped with dyadically. In this systematic review, we summarize research examining dyadic coping (DC) in the context of mental health and individual and relational outcomes. We searched for peer-reviewed articles published between January 1990 and April 2023 on PsycInfo, Medline, and PSYNDEX on DC and mental health within romantic relationships. A total of 60 qualitative, quantitative, and intervention studies met the inclusion criteria, reporting on 16,394 individuals and 4,945 dyads. To synthesize the studies, we used a narrative synthesis approach. Overall, stress expression and positive DC yielded beneficial individual and relational outcomes, whereas, for negative DC, the opposite was true. Results differed between mental health clusters and context played an important role (e.g., symptom severity, life phase). Due to the great diversity of studies and variables, further research should focus on understudied mental health clusters (e.g., anxiety disorders). Clinicians are advised to view mental health issues as a dyadic rather than an individual phenomenon (āwe-diseaseā) and develop tailored couple-centered interventions
Pilot Source Study 2018: Five Years after the FOQ RuleāNew-Hire First Officer Backgrounds and their Performance in US Regional Airline Training
After the Pilot Source Study (PSS) 2015 was published, there was concern that the data were collected too soon after the First Officer Qualification Rule compliance date. The Collaborative Research Committee of the Aviation Accreditation Board International (AABI) voted to undertake the PSS 2018 to determine whether the results of the PSS 2015 were still valid. In fall 2018, five research teams collected 9,776 pilot records from five regional airlines and analyzed these data. In the PSS 2018, the criteria for success were: ā„90% completions and ā¤1 extra training event. In rank order, the following pilots were most successful in regional airline initial training: (1) pilots who had an undergraduate GPA of 3.3 or higher, (2) pilots who graduated from college within 5 years of their hire date, (3) pilots who had either a military R-ATP (750 hours) or an institutional R-ATP (1,000 hours), (4) pilots who graduated from an AABI-accredited flight program, (5) pilots who had 1,500 or fewer total flight hours, (6) pilots who had a bachelor degree. In addition to these variables, multivariate analysis showed that the following variables provide additional prediction and classification for success: age, younger; flight instructor, yes; military pilot, yes; previous FAA failures, fewer. All four PSSs (2010, 2012, 2015, and 2018) have substantiated the 2010 ANPRM statement: āāā¦experience is not measured in flight time aloneāā
The appearance of literacy in new communicative practices: interrogating the politics of noticing
This conceptual article examines how ready-made assumptions about literacy both frame and
limit understandings of new communicative practices in educational contexts. Proposing a
tripartite heuristic that interrogates the appearance of literacy in terms of emergence,
semblance, and performance, it uses stories from a study of touchscreen tablets in one early
years setting to illustrate the social-material arrangements associated with moments when
tablets became texts to be looked at, shared or made. We argue that a sociomaterial
sensibility can not only sensitise researchers to new communicative practices, but also to the
ways in which sociomaterial arrangements help to construct habits of noticing often active in
accounts of literacy practice and research. It is our contention that exploring the relations
between emergence, semblance and performance is particularly valuable at a time when
conceptualisations of literacy are being challenged in response to diversifying communicative
practices
