Qualitative Transcendental Phenomenological Study of High Attrition Rates of Special Education Teachers Working with Students Who Have Severe Disabilities or Emotional Behavioral Disorders

The purpose of this qualitative transcendental phenomenological study was to understand why special education teachers who worked with students with severe disabilities or emotional and behavioral disorders (EBD) experienced elevated stress levels and burnout, resulting in high attrition and migration rates. The central research question guiding this study was: What were the leading causes of attrition and migration among teachers who taught students with severe disabilities or EBD in separate settings outside the general education population? This study, guided by Maslow\u27s motivation theory, explored attrition factors among 10 special education teachers in the United States who had taught students with severe disabilities or EBD. Using individual interviews, reflective journals, and focus groups recorded on Microsoft Teams, data were transcribed and analyzed. Interpretative phenomenological analysis (IPA) was applied to individual interviews, thematic analysis to journal responses, and a four-step coding process to focus group interviews. Results highlighted inadequate support, administrative challenges, and financial issues as key contributors to attrition. Teacher stress and burnout stemmed from heavy workloads, paperwork, low pay, and pressure to meet academic standards. The study suggested addressing these issues through improved support, tailored professional development, competitive compensation, and a supportive work environment to enhance teacher retention

“It's been quite a challenge”: Redesigning end-of-life care in acute hospitals

AbstractObjective:This paper reports the findings of an interview-based study undertaken to investigate the introduction of end-of-life (EoL) care pathways in three acute trusts, as part of a larger project examining service redesign. The aim was to examine the barriers to and facilitators of change.Method:Twenty-one in-depth qualitative interviews were conducted with staff working in three National Health Service (NHS) acute hospital trusts. These staff members were involved in end-of-life care, and their accounts were analyzed to identify the key issues when introducing service changes in these settings.Results:Thematic analysis revealed five major themes—two of which, leadership and facilitation, and education and training, indicate what needs to be in place if end-of-life care pathways are to be adopted by staff. However, the remaining three themes of difficult conversations, diagnosing dying, and communication across boundaries highlight particular areas of practice and organization that need to be addressed before end-of-life care in hospitals can be improved.Significance of results:Organization of end-of-life care in acute hospitals is challenging, and care pathways provide a degree of guidance as to how services can be delivered. However, even when there is effective leadership at all levels of an organization and an extensive program of education for all staff support the use of care pathways, significant barriers to their introduction remain. These include staff anxieties concerning diagnosing dying and discussing dying and end-of-life care planning with patients and their families. It is hoped these findings can inform the development of the proposed new care plans which are set to replace end of life care pathways in England.</jats:sec

Frequency, intensity and duration of physical tasks performed by Australian rural firefighters during bushfire suppression

The current study combined, for the first time, video footage of individual firefighters wearing heart rate monitors and personal GPS units to quantify the frequency, duration and intensity of tasks performed by Australian rural fire crews when. suppressing bushfires. Across the four fireground \u27shifts\u27, the firefighters performed 34 distinct fireground tasks. Per shift, the task frequency ranged from once (raking fireline in teams, carrying a quick fill pump) to 103 times {lateral repositioning of a 38-mm charged firehose) .. The tasks lasted between 4 &plusmn; 2 s (bowling out 3-8-mm firehose) and 461 &plusmn; 387 s (raking fireline in teams). The task intensity~ as measured by average heart rate ranged between 97 &plusmn; 16 beats&middot;min-1 (55.7 &plusmn; 8.7. %HRmax) and 157 &plusmn; 15 beats&middot;min-1 (86.2 &plusmn; 10.8 %HRmax)&middot; The tasks were performed a speeds that ranged from 0.12 &plusmn; 0.08 m&middot;s-1 (manual hose retraction of 38-mm charged firehose) to 0.79 &plusmn; 0.40 m&middot;s-1 (carrying a 38-mm coiled hose). Tasks found to be simultaneously frequent, long and intense (or two of these three) are likely to form the basis for job-specific testing of Australian rural firefighters suppressing bushfires.<br /

Design of a valid simulation for researching physical, physiological and cognitive performance in volunteer firefighters during bushfire deployment.

Every year, Australian firefighters protect our nation from the devastation of bushfire. Understanding the impact of consecutive long shifts in hot, smoky conditions is essential for making decisions during campaign fires. At present, the evidence-base for such decisions is limited to laboratory studies with little relevance to bushfire suppression or field research where the impact of environmental and workload stressors cannot be measured. To counter these limitations, we have developed a three-day simulation that mimics the work and environment of campaign bushfire suppression. Construction of the simulation involved three stages; 1) data collection and analysis; 2) design and development; and 3) trial and refinement. The frequency, intensity, duration and type of physical work performed on the fireground is well documented and a modified applied cognitive task analysis, using experienced firefighters was used as a framework to describe in detail the non-physical aspects of the work. The design and development of the simulation incorporated the physical and non-physical aspects of the work into simulated tasks. Finally, experienced firefighters participated in trials of the simulation and reviewed digital recordings to ensure that the simulation accurately represented campaign bushfire suppression work. The outcome of this project is a valid, realistic, and reliable simulation of the physiological, physical and cognitive aspects of a volunteer firefighter on a three-day bushfire deployment.<br /

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Assessing the validity of tympanic temperature to predict core temperature of firefighters in different environmental conditions

The present study examined the validity of tympanic temperature measurements as a predictor of core temperature on the fireground in different environmental conditions. Fiftyone volunteer firefighters participated in the study across four different conditions, the conditions consisted of; 1) passive (i.e., no intervention) cooling in cold ambient temperatures (0-6&deg;C); 2) cooling (through water immersion) in cool ambient temperatures (10-12&ordm;C); 3) cooling (through water immersion) in warm ambient temperatures (21.5&deg;C); and, 4) passive cooling in warm ambient temperatures (22&deg;C). Firefighters wore full structural personal protective clothing while performing common firefighting duties including search and rescue tasks for 20-40 minutes. There was no difference between core and tympanic temperature immediately post-exercise across any condition. However, for all conditions, tympanic temperature dropped significantly faster than core temperature from 0 minutes, and remained significantly lower (p &lt; 0.05) than core temperature from nine to 20 minutes post-training. The results show that there is no consistent difference between core and tympanic temperature during recovery from a simulated firefighting task across a range of different ambient conditions. Agencies should, accordingly, prioritize investigating other practical markers of core temperature as part of a broader heat stress management plan for firefighters

Identification of physically demanding tasks performed during bushfire suppression by Australian ruralfirefighters

Purpose To identify and characterize the physically demanding tasks undertaken during multi-day wildfire (known as bushfire in Australia) suppression by Australian rural firefighters. Methods During semi-structured group interviews, thirty-one experienced male firefighters reviewed 53 firefighting tasks that could be performed during tanker-based bushfire suppression. Participants were asked to nominate the most physically demanding tasks and then define their typical frequencies, durations, operational importance and the dominant actions and activity types in each task. Results Seven tasks were identified as physically demanding. They were further categorized into three hose and four handtool (e.g., rakehoe) related activities. These tasks were assessed as moderately important to critical and were thought to occur less than one up to 700 times in a four-month bushfire ‘season’. Each task’s duration was estimated to last approximately 2–30 min depending on the task. Dominant actions were carry, drag, dig/rake actions in seven, three and four of the demanding tasks, respectively. ‘Strength-endurance’ was the dominant activity type for five of the seven tasks. Conclusion Seven fireground tasks, three using a hose and four using handtools were classified as physically demanding by incumbent firefighters. The combination of hose and handtool work indicates that the tanker-based bushfire suppression tactics used by Australian rural firefighters appears to be a hybrid of structural and wildfire firefighting techniques and may require a dedicated physiological analyses before the job demands for these firefighters can be quantified

Muscle activation during the Pack Hike test and a critical wildfire fighting task

The aim of this study was to examine the muscle activation of six global muscles during the successful completion of the Pack Hike test (PHT) and compare this to muscle activations during a critical wildfire fighting task. In-field surface electromyography was recorded from eight male wildfire fighters during the PHT and the rakehoe task – a critical wildfire suppression activity. All participants successfully completed the PHT within the 45-min time limit. No significant changes in peak muscle activation levels as well as no significant shifts in median frequency in the six muscle analysed were recorded during the 4.83-km hike. Significantly different peak muscle activation levels were recorded in four of the six muscles tested when the PHT was compared to the rakehoe task. These results suggest the PHT should not be administered in isolation and other tests that specifically challenge upper body muscle endurance should be incorporated into a battery that accurately assesses the job-specific fitness of wildfire fighter
