Maritime free space optical communications field test and link budget statistics.

During sub-optimal weather, a free-space optical (FSO) link range degrades depending on attenuation (atmospheric extinction) and turbulence effects. The ability to predict the system level performance can be exceedingly challenging as the atmospheric variability in a maritime link can be large and difficult to model. Link budget estimation for FSO systems often takes a nominal view of atmospheric conditions; here, we use statistical atmospheric predictions specific to a geographic area of interest to enable performance trades to be evaluated through link budget analysis. We compare these models to field-collected data to show the utility of the statistical atmospheric analysis in predicting FSO link performance for specific parts of the world. We have performed shore-to-ship FSO communications field tests at 10 Gb/s with links reaching out to a horizon limit over 40 km away in times of moderate extinction to clear weather. We provide further analysis by describing the expected performance of the link using statistical probabilities via cumulative distribution functions of both extinction and turbulence. The atmospheric variability can be determined for nearly any region of interest through the implementation of numerical weather prediction data to calculate the atmospheric performance drivers. These conditions are specifically evaluated for the 2017 Trident Warrior field test off the coast of San Diego, California, USA.

"This is it this is our normal" - the voices of family members and first responders experiencing duty-related trauma in Ireland.

BACKGROUND: Compared to other occupational groups, first responders (FR) experience worse mental health outcomes due to duty-related trauma and occupational stressors. Despite their best efforts, they bring this stress home to friends and family. Consequently, FR and their supporters suffer from increased psychosocial difficulties and experience stigma and other barriers to help-seeking. Prior work offers little opportunity for open dialogue and shared understanding of the repercussions of this occupation for all members of the first responder community. In this qualitative study, we aimed to: (i) explore the lived experience of Irish FR and their family members (FM) related to occupational stressors, and (ii) identify opportunities to engage FM with existing organizational supports available for FR. METHODS: Using a community based participatory research (CBPR) approach, we conducted six focus groups involving a total of fourteen participants comprising FR, organizational representatives, and FM. All focus groups were audio recorded, transcribed, and analyzed using reflexive thematic analysis. FINDINGS: FR and FM shared their experiences of both joining and learning to live as members of the FR community in Ireland. Through our analysis, we identified a main theme of 'crossing thresholds', characterizing their transformative learning experiences. This learning experience includes recognizing the consequences of this new role for them as individuals and for their relationships. Participants also shared how they have learned to cope with the consequences of their roles and what they need to better support each other. CONCLUSIONS: FM are often unheard, hidden members of the first responder community in Ireland, highlighting an unmet need for FR organizations to acknowledge FM role in supporting FR and to provide them with the appropriate training and resources required. Training for new recruits needs to move beyond the tokenistic involvement of FM and encourage knowledge sharing among experienced and novice members. Cultural change is required to support help-seeking among FR and foster a sense of peer support and community among families.

'They mirror what they see': A constructivist grounded theory study of simulation culture in four professional domains in Ireland.

PURPOSE: In simulation-based education (SBE), educators integrate their professional experiences to prepare learners for real world practice and may embed unproductive stereotypical biases. Although learning culture influences educational practices, the interactions between professional culture and SBE remain less clear. This study explores how professional learning culture informs simulation practices in healthcare, law, teacher training and paramedicine. METHODS: Using constructivist grounded theory, we interviewed 19 educators about their experiences in designing and delivering simulation-based communication training. Data collection and analysis occurred iteratively via constant comparison, memo-writing and reflexive analytical discussions to identify themes and explore their relationships. RESULTS: Varied conceptualizations and enactments of SBE contributed to distinct professional learning cultures. We identified a unique 'simulation culture' in each profession, which reflected a hyper-real representation of professional practice shaped by three interrelated elements: purpose and rationale for SBE, professional values and beliefs, and educational customs and techniques. Dynamic simulation cultures created tensions that may help or hinder learning for later interprofessional practice. CONCLUSION: The concept of simulation culture enhances our understanding of SBE. Simulation educators must be mindful of their uni-professional learning culture and its impacts. Sharing knowledge about simulation practices across professional boundaries may enhance interprofessional education and learners' professional practice.

Training simulated participants for role portrayal and feedback practices in communication skills training: A BEME scoping review: BEME Guide No. 86.

BACKGROUND: Providing feedback is a key aspect of simulated participants' (SPs) educational work. In teaching contexts, the ability to provide feedback to learners is central to their role. Suboptimal feedback practices may deny learners the valuable feedback they need to learn and improve. This scoping review systematically maps the evidence related to SPs' role as educators and identifies how SPs prepare for their role and feedback practices. METHODS: The authors conducted a scoping review and included a group of international stakeholders with experience and expertise in SP methodology. Five online databases were systematically searched and ERIC, MedEdPortal and MedEdPublish were hand searched to identify relevant studies. Inclusion/exclusion criteria were developed. Data screening and subsequently data charting were performed in pairs. The results of data charting were thematically analysed including categories relating to the Association of SP Educators (ASPE) Standards of Best Practice (SOBP). RESULTS: From 8179 articles identified for the title and abstract screening, 98 studies were included. Studies reported the benefit of SPs' authentic role portrayal and feedback interactions for learners and on the reported learning outcomes. Data was heterogeneous with a notable lack of consistency in the detail regarding the scenario formats for communication skills training interventions, SP characteristics, and approaches to training for feedback and role portrayal. CONCLUSIONS: The published literature has considerable heterogeneity in reporting how SPs are prepared for role portrayal and feedback interactions. Additionally, our work has identified gaps in the implementation of the ASPE SOBP, which promotes effective SP-learner feedback interactions. Further research is required to identify effective applications of SP methodology to prepare SPs for their role as educators.

'How can we help the students learn?' A grounded theory study of simulated participants as educators.

PURPOSE: Despite the demonstrated value of simulated participant (SP) feedback, we are only beginning to understand how to optimize SPs' feedback practices for communication skills and strengthen their role as educators. SPs portray roles and engage in feedback practices to support simulated-based learning for communication skills training. SPs come to their role with diverse experiences, knowledge, and training, such as (a) professional actors, (b) lay people, and (c) health professions educators. This study explored what factors influenced SPs' role as educators, including their preparation, training, and approach to role portrayal and feedback practices and how these aspects were influenced by SPs' backgrounds. METHODS: Using grounded theory methodology, we collected and analysed data iteratively from 16 semi-structured in-depth interviews. We identified key concepts, using constant comparison and by exploring how concepts were related , to develop a conceptual model of SPs as educators. RESULTS: The SP role as educator was shaped by several interrelated dualities which spanned both the SP and learner roles and contributed to the identity formation of both SP and learner: (a) building competence (SP competence as educator and learner competence as healthcare professional), (b) engaging in reflective practice (SPs prompting learner reflection and SPs reflecting on their own role), and (c) establishing a safe space (SP needing to feel safe in their role to create safety to support learner engagement). SPs' backgrounds influenced how they learned to portray roles and how they engaged in feedback practices, both in-action, through in-role prompts and cues, and on-action, through post-scenario feedback discussions. CONCLUSION: Our conceptual model about SPs as educators informs SP selection and training. Further, this model enables practical suggestions for SP educators and faculty who involve SPs in teaching. Enhanced feedback practices have the potential to improve learning from simulated encounters.

Breaking down barriers to help-seeking: preparing first responders' families for psychological first aid.

Background: First responders regularly encounter both operational stressors and potentially traumatic events, increasing their risk of mental health issues (Declercq et al., 2011). Due to unique cultural complexities, they turn mostly to peers for early psychosocial support (Isaac & Buchanan, 2021). However, peer support and/or mental health assistance may not always be available or easy to access and first responders' mental health suffers. Objective: We need more accessible routes to crisis intervention to ensure first responder resilience and wellbeing, so they may continue to function in the service of public safety. Family members and close friends may be ideally placed to provide this immediate care. This article outlines the protective role of social support as an early intervention strategy to mitigate the effects of first responder trauma, exploring the potential opportunity for family members and friends to play an increasingly supportive role in their loved one's wellbeing. This paper serves as a call to action for practical educational interventions that will prepare family members for these critical conversations. Conclusion: We see potential in combining early intervention theory, psychoeducation, and a strengths-based gender specific positive psychology approach. Further study should investigate how best to help first responders break down barriers to support, by bolstering their existing social supports and ultimately reducing the stigma associated with experiencing traumatic stress. HIGHLIGHTS: By training family members in psychological first aid, we may strengthen existing social support for first responders, providing more options for, and potentially breaking down stigma associated with help-seeking.

Antecedentes: Los equipos de primera respuesta se encuentran regularmente con estresores operacionales y eventos potencialmente traumáticos, aumentando su riesgo de problemas de salud mental. Debido a las complejidades culturales únicas, ellos se dirigen a sus pares por apoyo psicosocial temprano. Sin embargo, el apoyo de pares y/o la asistencia de salud mental puede que no esté siempre disponible o sea de fácil acceso y la salud mental de los equipos de primera respuesta se resiente.Objetivo: Se necesitan rutas más accesibles para la intervención en crisis para asegurar la resiliencia y el bienestar de los equipos de primera respuesta, entonces ellos podrían continuar funcionando en el servicio de la seguridad pública. Los familiares y los amigos cercanos podrían estar en posición de otorgar este apoyo inmediato. Este artículo presenta el rol protector del apoyo social como una estrategia de intervención temprana para mitigar los efectos del trauma de los equipos de primera respuesta, explorando la oportunidad potencial de los familiares y amigos para jugar un rol creciente de apoyo en el bienestar de sus seres queridos. Este artículo sirve como un llamado a la acción para intervenciones educacionales prácticas que prepararan a los familiares para estas conversaciones críticas.Conclusión: Vemos un potencial en combinar las perspectivas de la teoría de intervención temprana, psicoeducación, y psicología positiva especifica de género basado en las fortalezas. Las investigaciones futuras deberían investigar cómo se puede ayudar de mejor forma los equipos de primera respuesta para derribar las barreras al apoyo, fortaleciendo sus redes sociales actuales y así reducir el estigma asociado con la experiencia de estrés traumático.

Turning to 'Trusted Others': A Narrative Review of Providing Social Support to First Responders.

First responders, such as paramedics and firefighters, encounter duty-related traumatic exposures, which can lead to post-traumatic stress (PTS). Although social support protects against PTS, we know little about how first responders' families, spouses/partners, friends, and care-partners (i.e., 'trusted others') provide social support. This narrative review explores support behaviors, coping strategies, and resources trusted others use to support first responders. A structured literature search yielded 24 articles. We used House's (1981) conceptual framework to inform our analysis. We identified three main themes: providing support, finding support, and support needs. Additionally, we describe trusted others' self-reported preparedness, coping strategies, and barriers to providing social support. We found that trusted others provided different types of support: (a) emotional (fostering a safe space, giving autonomy over recovery, facilitating coping mechanisms, prioritizing first responders' emotional needs); (b) instrumental (prioritizing first responders' practical needs, handling household tasks, supporting recovery); (c) appraisal (active monitoring, verbal reassurance, positive reframing), and (d) informational (seeking informal learning). In their role, trusted others sought formal (organizational) and informal (peer and personal) support and resources, alongside intrapersonal and interpersonal coping strategies. Identified barriers include inadequate communication skills, maladaptive coping, and disempowering beliefs. Thus, we offer practical, treatment, and social support recommendations.
