Using automated active infrared counters to estimate footfall on urban park footpaths: behavioural stability and validity testing.

BACKGROUND: Using infrared counters is a promising unobtrusive method of assessing footfall in urban parks. However, infrared counters are susceptible to reliability and validity issues, and there is limited guidance for their use. The aims of this study were to (1) determine how many weeks of automated active infrared count data would provide behaviourally stable estimates of urban park footfall for each meteorological season, and (2) determine the validity of automated active infrared count estimates of footfall in comparison to direct manual observation counts. METHODS: Three automated active infrared counters collected daily footfall counts for 365 days on three footpaths in an urban park within Northampton, England, between May 2021 - May 2022. Intraclass correlation coefficients were used to compare the behavioural stability of abbreviated data collection schedules with total median footfall within each meteorological season (Spring, Summer, Autumn, Winter). Public holidays, events, and extreme outliers were removed. Ten one-hour manual observations were conducted at the site of an infrared counter to determine the validity of the infrared counter. RESULTS: At least four-weeks (28 days) of infrared counts are required to provide 'good' to 'excellent' (Intraclass correlation > 0.75, > 0.9, respectively) estimates of median daily footfall per meteorological season in an urban park. Infrared counters had, on average, -4.65 counts per hour (95% LoA -12.4, 3.14; Mean absolute percentage error 13.7%) lower counts compared to manual observation counts during one-hour observation periods (23.2 ± 15.6, 27.9 ± 18.9 counts per hour, respectively). Infrared counts explained 98% of the variance in manual observation counts. The number of groups during an observation period explained 78% of the variance in the difference between infrared and manual counts. CONCLUSIONS: Abbreviated data collection schedules can still obtain estimates of urban park footfall. Automated active infrared counts are strongly associated with manual counts; however, they tend to underestimate footfall, often due to people in groups. Methodological and practical recommendations are provided.

Mapeamento da produção artístico-acadêmica de Dança nos programas brasileiros de pós-graduação em Artes: um olhar sobre os métodos de investigação / Mapping the artistic-academic production of Dance in brazilian postgraduate Arts programs: a look at research methods / Mapeo de la producción artístico-académica de la Danza en los programas de posgrado en Arte brasileños: una mirada a los métodos de investigación

Este artigo teve como objetivo identificar a localidade da Dança nos métodos de pesquisa das teses e dissertações, produzidas entre 2016-2020, nos programas de pós-graduação em Artes no Brasil. O percurso metodológico, de caráter descritivo, se deu a partir da observação da lógica adotada na organização das investigações (produção de uma performance, distanciamento para teorizar, utilização para fins dedutivos) e classificou a localidade da Dança como: (a) produção e interpretação dos dados; (b) objeto; (c) experimento. O estudo constatou que a maior parte dos trabalhos, de acordo com o período levantado, localizam a Dança nos seus percursos metodológicos como objeto de estudo. Apesar da busca por um caminho do exercício de observação e teorização, percebe-se que existe um amplo leque de possibilidades de experimentações, desdobramentos, especulações e conjecturas sobre o lugar da Dança nos métodos de pesquisas brasileiros (AU).

This article aimed to identify the location of Dance in the research methods of theses and dissertations, produced bet-ween 2016-2020, in postgraduate programs in Arts in Brazil. The methodological course, of a descriptive character, was based on the observation of the logic adopted in the organization of investi-gations (production of a performance, distance to theorize, use for deductive purposes) and classified the locality of Dance as: (a) pro-duction and interpretation of the data; (b) object; (c) experiment. The study found that most of the works, according to the period surveyed, locate Dance in their methodological paths as an object of study. Despite the search for a way of exercising observation and theorization, it is clear that there is a wide range of possibili-ties for experimentation, developments, speculations and conjec-tures about the place of Dance in Brazilian research methods (AU).

Efeito da padronização dos critérios de observação e de avaliação da técnica da braça do nado crawl na confiabilidade inter e intra avaliadores / Effect of standardizing observation and rating criteria for the front crawl stroke technique on inter- and intra-rater reliability

RESUMO Esse estudo teve por objetivo avaliar o efeito da padronização dos critérios de observação e de avaliação da técnica da braçada do nado crawl na confiabilidade inter e intra avaliadores para uma proposta de lista de observação. Dois professores e dois treinadores de natação competitiva com formação acadêmica diferentes foram responsáveis por avaliar a técnica da braçada do nado crawl de 44 nadadores por meio de vídeo. Cada nadador realizou um percurso de 25m em velocidade confortável tendo seu deslocamento gravado nos planos lateral e frontal, ambos submersos e fora d'água, nos 10 m finais da piscina. No percurso de filmagem os nadadores não realizaram a respiração lateral. Somente o movimento realizado pelo braço direito foi foco de observação dos avaliadores e com base em uma lista de verificação. Após as filmagens os avaliadores participaram de três etapas: na primeira etapa houve uma intervenção para padronização dos critérios de observação e de avaliação. Na segunda etapa testou-se a concordância inter-avaliadores e, na terceira, a concordância intra-avaliador. Na segunda etapa do estudo a concordância variou de pequeno a baixa (k=0,08 e k=0,38). Na terceira etapa alguns avaliadores apresentaram concordância pobre e baixa (k=-0,13 e k=0,35), enquanto outros apresentaram concordância entre razoável e praticamente perfeita (k=0,64 e k=0,87). A partir dos resultados apresentados concluiu-se que a proposta de intervenção não surtiu o efeito desejado de padronização dos critérios de observação e avaliação entre os avaliadores.

ABSTRACT This study aimed to assess the effect of standardizing observation and rating criteria for the front crawl stroke technique on inter- and intra-rater reliability in order to propose an observation list. Two teachers and two competitive swimming coaches with different academic backgrounds were responsible for evaluating the front crawl stroke technique of 44 swimmers using video. Each swimmer completed a 25m course at a comfortable speed, having their displacement recorded in the lateral and frontal planes, both submerged and out of water, in the final 10 m of the pool. Throughout the recording, the swimmers did not breath laterally. Only the movement performed by the right arm was the raters' focus of observation and was based on a checklist. After the shooting, the raters participated in three stages: in the first stage, there was an intervention to standardize the observation and rating criteria; inter-rater agreement was tested in the second stage, while intra-rater agreement was obtained in the third. In the second stage of the study, the agreement ranged from small to low (k=0.08 and k=0.38). In the third stage, some raters showed poor and low agreement (k=-0.13 and k=0.35), while others showed agreement between reasonable and virtually perfect (k=0.64 and k=0.87). From the results presented, it was concluded that the intervention proposal did not have the desired effect of standardizing the observation and rating criteria among the raters.

Os desamparos da maternidade em um contexto de vulnerabilidade social / The helplessness of motherhood in a context of social vulnerability / El desamparo de la maternidade en un contexto de vulnerabilidad social

Algumas mães, mesmo acompanhadas de um parceiro, desempenham solitariamente múltiplos papéis, cuidando da rotina de casa, do trabalho e, precariamente, de si mesmas. Com o objetivo de discutir a maternidade em um contexto de vulnerabilidade e suas implicações no estabelecimento da relação mãe e filhos, a partir de um caso, utilizou-se um método observacional psicanalítico inspirado no Método Bick de Observação, sendo uma pesquisa qualitativa. As observações foram realizadas considerando os três tempos: observação semanal, no mesmo dia e hora; relato da observação, de forma descritiva e implicada; e, seminário de supervisão, para discussão das observações. Evidenciou-se o desamparo sentido por essa mulher-mãe que, apesar da presença da família e do esposo, não recebia o apoio necessário. Sua exaustão, oriunda do desamparo, resultava em perda de controle emocional em relação aos filhos. Ressalta-se o valor do Método Bick de Observação ao possibilitar um olhar sensível à maternidade

Some mothers, even when joined by a partner, end up playing multiple roles alone, taking care of the household chores, their work lives and, precariously, of themselves. In order to discuss motherhood in a context of vulnerability and its implications in the establishing of the relationship between a mother and her children, based on a specific case, an psychoanalytic observational method inspired by the Bick Method of Observation was employed, being a qualitative research. The observations were carried out considering three tempos: weekly observation, on the same day and time; observation report, in an involved and descriptive way; and supervision seminar, to discuss the observations. It was made evident the helplessness experienced by this woman-mother, who, despite the presence of her husband and family, did not receive the necessary support. Her exhaustion, stemming from this helplessness, resulted in a loss of emotional control over her children. The value of the Bick Observation Method is highlighted, as it enables a sensitive outlook towards motherhood

Algunas madres, incluso las acompañadas de pareja, desempeñan múltiples papeles solas, cuidando la rutina de la casa, el trabajo y, precariamente, ellas mismas. Para discutir la maternidad en un contexto de vulnerabilidad y sus implicaciones para el establecimiento de la relación entre las madres y sus hijos, a partir de un caso, se utilizó un método observacional psicoanalítico inspirado en el Método de Observación Bick, haciendo de esta una investigación cualitativa. Las observaciones se realizaron considerando los tres tiempos: observación semanal, en el mismo día y hora; informe de la observación, de forma descriptiva y implícita; y, seminario de supervisión, para discutir las observaciones. Se hizo evidente el desamparo que siente esta mujer-madre, quien, a pesar de la presencia de su familia y esposo, no recibe el apoyo necesario. Su agotamiento, derivado del desamparo, resultó en una pérdida del control emocional sobre sus hijos. Se destaca el valor del método de observación de Bick, que permite una mirada sensible a la maternidad

Uso del método de observación: una propuesta de aplicación al análisis de estrategias de resolución de problemas en niños con discapacidad / Use of observational method: a proposal for application to the analysis of problem-solving strategies in children with disabilities

El presente trabajo se ocupa de evaluar posibilidades del método de observación aplicado al análisis de estrategias de resolución de problemas en niños con discapacidad mediante juegos y tareas estructuradas. El marco teórico de referencia de esta contribución está representado por la teoría de la resolución de problemas, que contiene los principales procesos que intervienen en la gestión de los problemas y que nosotros aplicamos al desarrollo cognitivo y metacognitivo atípico. Junto con tres tareas diferentes estructuradas(Torre de Hanoi, Tetris y Bloques de construcción), usamos dos listas de comportamientos para codificar estrategias de resolución de problemas adoptadas por niños y/o adolescentes con desarrollo atípico. La aplicación de este tipo de observación con el uso de listas de comportamientos podría ser útil para crear en relación entre la investigación cualitativa y cuantitativa para mejorar el conocimiento de las estrategias de resolución de problemas y competencias metacognitivas en niños desarrollados atípicos(AU)

This paper is concerned with evaluating the possibilities of the observational method applied to the analysis of problem-solving strategies in children with disabilities through structured tasks. The theoretical framework of reference for this contribution is represented by the theory of problem-solving, containing the main processes involved in problem management,which we apply to atypical cognitive and metacognitive development. Together with three different structured tasks (Tower of Hanoi, Tetris, and Building Blocks), we used two lists of behaviors to code problem-solving strategies adopted by children and/or adolescents with atypical development. The application of this type of observation with the use of lists of behaviors could be useful to create a link between qualitative and quantitative research to improve the knowledge of problem-solving strategies and metacognitive competencies in atypically developed children(AU)

Agujero Timpánico bilateral. Análisis de caso desde la literatura / Bilateral tympanic hole. Case analysis from the literature

La pared del conducto auditivo externo (CAE) parte de la formación del hueso timpánico; integrándose posteriormente a la porción petrosa del hueso temporal. El agujero timpánico o foramen de Huschke corresponde a un defecto en la osificación en donde existe fusión incompleta de porciones anteriores y posteriores del anillo timpánico dejando una abertura que comunica el CAE hacia anterior. Su presencia es normal hasta los 5 años de edad, tiempo en que se debiese obliterar. Su incidencia es baja (3-24%), pero la persistencia en adulto, conlleva sintomatología inespecífica caracterizada por otalgia, dolor en articulación temporomandibular (ATM), tinnitus, hipoacusia o manifestaciones complejas como descarga salival en CAE durante la masticación. Clínicamente puede complicar procedimientos de infiltración y artroscopias de ATM. Rara vez ocasiona, en pacientes mayores de 50 años, herniación de la cabeza del cóndilo mandibular. Su diagnóstico puede ser clínico por medio de otoscopia, donde se observa protuberancia de tejido en pared anterior del CAE, que aumenta de tamaño con la boca cerrada. También puede ser imagenológico con una tomografía computarizada. El tratamiento incluye desde medidas conservadoras para manejo del dolor e inflamación, hasta quirúrgicas con la implantación de injertos, placas o prótesis para cerrar la estructura o para reemplazar el cóndilo mandibular. El presente estudio pretende aportar incidencia dentro del área de estudio. Se analiza por observación directa, cráneo seco, completo, masculino, edad entre 12 a 15 años (según morfología del cóndilo mandibular y erupción dental). Se observa agujero de Huschke, bilateral, ambos permeables de diámetro 4 mm en ambos casos, determinados con regla milimetrada. La relevancia del defecto se asocia a la práctica clínica de otorrinolaringólogos, cirujanos maxilofaciales y odontólogos, ya sea como diagnóstico diferencial asociado a los síntomas inespecíficos, como para procedimientos más invasivos en la zona tales como infiltraciones o artroscopias de ATM

The wall of the external auditory canal (EAC) starts from the formation of the tympanic bone; later it is integrated to the petrous portion of the temporal bone. The tympanic foramen or foramen of Huschke corresponds to a defect in ossification where there is incomplete fusion of the anterior and posterior portions of the tympanic ring leaving an opening that communicates the EAC to its anterior aspect. Its presence is normal until 5 years of age, when it should be absolutely obliterated. Its incidence is low (3-24%), but its persistence in adults leads to non specific symptoms characterized by otalgia, pain in the temporomandibular joint (TMJ), tinnitus, hearing loss, or complex manifestations such as salivary discharge in the CAE during mastication. Clinically, it may complicate TMJ infiltration and arthroscopy procedures. It rarely causes herniation of the mandibular condyle head in patients older than 50 years. Its diagnosis can be clinical by means of otoscopy, where tissue protrusion is observed in the anterior wall of the CAE, which increases in size when the mouth is closed. It can also be imaging with computed tomography. Treatment includes from conservative measures to treat pain and inflammation, to surgical measures with the implantation of grafts, plates or prosthesis to close the structure or to replace the mandibular condyle. The present study aims to provide incidence within the study area. It is analyzed by direct observation, dry skull, complete, male, age between 12 to 15 years (according to mandibular condyle morphology and dental eruption). Huschke's foramen was observed, bilateral, both permeable, diameter 4mm in both cases, determined with a millimeter ruler. The relevance of the defect is associated with the clinical practice of otolaryngologists, maxillofacial surgeons and dentists, either as a differential diagnosis associated with nonspecific symptoms, or for more invasive procedures in the area such as infiltrations or TMJ arthroscopies.

Comparison of Fine Arts- and Pathology-Based Observational Skills Training for Veterinary Students Learning Cytology.

Keen observational skills are essential for veterinarians; however, the development of these skills is not usually an explicit part of the veterinary curriculum. Fine arts-based (FAB) observation training has been shown to improve medical students' observational skills and might also improve veterinary students' observational skills. We compared FAB and pathology-based (PB) observation training in a veterinary cytology course. Students initially wrote a pre-test in which they described two cytology images and one art image, followed by participation in either FAB or PB observation training. Both groups completed a similar post-test immediately after training and a delayed post-test 4 weeks later following instruction in cytology. Differences between groups were noted only in the immediate post-test cytology descriptions. The PB group used significantly more specific vocabulary terms and significantly more accurate observations than the FAB group, suggesting an immediate benefit to the discipline-specific information gained in the PB observation training. In the delayed post-test, results for both groups were similar. The FAB group significantly increased their use of specific vocabulary terms and maintained but did not increase accurate observations following cytology instruction, while accurate observations decreased significantly for the PB group. The FAB group might have been able to generalize their observation skills to the discipline of cytology and to better retain these skills. Neither type of training resulted in both achievement and maintenance of the highest recorded scores for accurate observations. Both FAB and PB training led to improved observational skills, and explicit observation training may be useful for veterinary students.

Ambiente de ensino-aprendizagem na formação inicial universitária / Teaching-learning environment in initial university training in physical education

ABSTRACT This study aimed to analyze the perceptions of university Physical Education students at different progression levels in the programs regarding the teaching-learning environment in the initial training. In total, 273 students (Bachelor's program n = 150; Licentiate program n = 123) from the Licentiate Program in Physical Education of a public university in Santa Catarina, Brazil, participated in this study, responding to the adapted version of the Assessment Questionnaire of the Perceived Environment in the Initial Training in Physical Education. The Chi-square test was used to analyze the associations between the student progression levels in the programs and their perceptions about the initial training environment. The results indicated the predominance of practical classes/experiences and written theoretical evaluations, especially in the initial phases. The infrequent observation experiences and learning through practice or observation were the assumed roles, made evident primarily in the final semesters. Although the students perceived themselves as active regarding their participation levels, they indicated that the professors are the ones responsible for making the decisions. It is concluded that the initial training in Physical Education requires reconfiguring certain teaching-learning practices to increase student involvement and responsibility for their own training process.

RESUMO Objetivou-se analisar as percepções de estudantes universitários de Educação Física em distintos níveis de progressão no curso, sobre o ambiente de ensino-aprendizagem na formação inicial. Participaram 273 estudantes (Bacharelado n=150; Licenciatura n=123) do curso de licenciatura em Educação Física de uma universidade pública de Santa Catarina, Brasil, os quais responderam à versão adaptada do Questionário de Avaliação do Ambiente Percebido da Formação Inicial em Educação Física. O teste Qui-quadrado foi utilizado para analisar as associações entre o nível de progressão discente nos cursos e suas percepções sobre o ambiente de formação inicial. Os resultados indicaram a predominância de aulas/vivências práticas e de avaliações teóricas escritas, especialmente nas fases iniciais. As experiências poucos frequentes de observação, e o aprendizado pela prática ou por observação foi o papel assumido, especialmente evidenciados nos semestres finais. Apesar de os estudantes terem se percebido ativos quanto ao seu nível de participação, indicaram que os professores são os principais responsáveis por tomar as decisões. Conclui-se que a formação inicial em Educação Física necessita reconfigurar determinadas práticas de ensino-aprendizagem para aumentar o envolvimento e a responsabilidade discentes pelo próprio processo formativo.

Communication as a High-Stakes Clinical Skill: "Just-in-Time" Simulation and Vicarious Observational Learning to Promote Patient- and Family-Centered Care and to Improve Trainee Skill.

Patient-provider communication is a hallmark of high-quality care and patient safety; however, the pace and increasingly complex challenges that face overextended teams strain even the most dedicated clinicians. The COVID-19 pandemic has further disrupted communication between clinicians and their patients and families. The dependence on phone communication and the physical barriers of protective gear limit nonverbal communication and diminish clinicians' ability to recognize and respond to emotion. Developing new approaches to teach communication skills to trainees who are often responsible for communicating with patients and their families is challenging, especially during a pandemic or other crisis. "Just-in-time" simulation-simulation-based training immediately before an intervention-provides the scaffolding and support trainees need for conducting difficult conversations, and it enhances patients' and families' experiences. Using a realistic scenario, the author illustrates key steps for effectively using just-in-time simulation-based communication training: assessing the learner's understanding of the situation; determining what aspects of the encounter may prove most challenging; providing a script as a cognitive aid; refreshing or teaching a specific skill; preparing learners emotionally through reflection and mental rehearsal; coaching on the approach, pace, and tone for a delivery that conveys empathy and meaning; and providing specific, honest, and curious feedback to close a performance gap. Additionally, the author acknowledges that clinical conditions sometimes require learning by observing rather than doing and has thus provided guidance for making the most of vicarious observational learning: identify potential challenges in the encounter and explicitly connect them to trainee learning goals, explain why a more advanced member of the team is conducting the conversation, ask the trainee to observe and prepare feedback, choose the location carefully, identify everyone's role at the beginning of the conversation, debrief, share reactions, and thank the trainee for their feedback and observations.

[How to adapt qualitative research to confinement contexts]. / Cómo adaptar una investigación cualitativa a contextos de confinamiento.

The confinement of the population, researchers, shows the need to adapt the qualitative methodology, techniques and tools, to the current context generated by COVID-19. The Internet and the social media allow the collection of textual data, sequences, images or narratives about a limited reality for access to it in person. We enter the era of e-research, nuancing and reorienting the observation, conversation, collection and analysis of information. Currently, we are working on techniques and models of good practice in this area. This note includes data collection tools used in qualitative research in health sciences, a selection of techniques for qualitative online research is made, and 10 rules for the design of an e-research of this type are provided.

Single session of action observation in choice reaction time in healthy children

Abstract Aim: Learning by action observation (AO) is a fundamental cognitive ability existing from birth either in live or in the video. However, the specific AO training, in live or in the video, can influence decision making and motor planning in healthy children? This study aimed to evaluate if a single session of both practices (live and video) modifies the choice reaction time during reaching tasks in healthy children. Methods: This is a cross-sectional and randomized study with 22 children aged 6 to 8 years. We measured the choice reaction time (CRT) by electromyography at baseline and after both practices. Data were analyzed using Friedman and posthoc Dunn non-parametric tests for each age group individually as well as all ages combined. Kurtosis analysis was performed to assess data variability. Results: Significant decrease in CRT was observed after action observation in the video in 8-year-olds. Also, we observed choice reaction time variability reduction in 8-year-olds after both practices compared to that at baseline. Conclusion: A decrease in CRT was observed after the single session of action observation in the video in 8-year-olds. Additionally, there was a reduced variability in CRT after performing both practices in the same age group.

Crawl technique observation sheet for beginning swimmers: an evaluation proposal for swimming teachers

Abstract Aims: This study aimed to present a technical evaluation proposal for the crawl stroke that can be used with large groups of swimmers, based on an observation sheet. Methods: Fifteen healthy university students aged between 18 and 30 years were chosen to participate in the study. The subjects were recorded swimming at a distance of 50 meters using the crawl technique at a comfortable and self-determined speed. The recordings simulated docent observation capacity. Five swimming teachers were selected to evaluate the proposed checklist and the subjects' technique. An observation sheet was created based on references present in literature containing ten items that are considered fundamental for swimming movements. The study was divided into (i) checklist validation, (ii) intra-evaluator consistency, and (iii) inter-evaluator consistency. Results: The proposed checklist fulfilled the validity criteria, with intra-evaluator consistency varying between reasonable and substantial, with k varying between 0.36 and 0.73 respectively, while inter-evaluator consistency was deemed reasonable (k = 0.24). Conclusion: According to the results that were obtained, the suggested list is valid and adequate for what it proposes to do.

Reliability of assessment methods for scapular dyskinesis in asymptomatic subjects: A systematic review.

OBJECTIVE: The aim of this systematic review was to evaluate the available published evidence on the intra- and inter-rater reliabilities of assessment methods used for identifying and measuring scapular dyskinesis (SD) in asymptomatic subjects. METHODS: A systematic electronic literature search was performed in PubMed, Physiotherapy Evidence Database, Scopus, and the Cochrane Library, and studies on the intra- and inter-rater reliabilities of physical examination tests used for identifying SD in asymptomatic people were identified. Methodological quality of the studies meeting the inclusion criteria was assessed using the Quality Appraisal of Reliability Studies (QAREL) checklist by two reviewers. The overall level of evidence of this systematic review was determined by the Modified Cochrane Back Pain Criteria based on previous research which was modified for reliability studies of the shoulder complex. RESULTS: The literature search generated 388 results, and only 14 articles met the inclusion criteria. In these studies, reliabilities of two qualitative and five quantitative methods for the assessment of SD were analyzed. The QAREL checklist revealed that 12 studies had moderate risk of bias and 2 had high risk of bias. Additionally, none of the studies were of high quality. On the basis of the Modified Cochrane Back Pain Criteria, the overall level of evidence was moderate. Most of the studies including quantitative measurement methods found good to excellent inter- and intra-rater reliability values. Most of the studies including qualitative methods found low-to-moderate intra- and inter-rater reliability values. CONCLUSION: Considering the available published evidence, there is lack of high-quality studies evaluating the inter- and intra-rater reliabilities of qualitative or quantitative methods used for the assessment of SD. There are no qualitative methods with high reliability that are fit for clinical applications. Some quantitative methods with higher reliability are present, but clinicians should be aware of the methodological flaws that studies evaluating these methods suffer from. LEVEL OF EVIDENCE: Level II, Diagnostic study.

Automatic incident detection on freeways based on Bluetooth traffic monitoring.

A novel automatic incident detection (AID) method for freeways, based on the use of data provided by Bluetooth sensors and an unsupervised anomaly detection approach, is presented. The two main advantages of the proposed AID system are: (i) the use of Bluetooth sensors offers several practical advantages over inductive loop detectors (ILD), which is one of the preferred sensing technology for traffic flow; and (ii) the unsupervised anomaly detection approach builds a model without the need of incident information. A common problem when designing an AID system is that incident information, i.e., ground-truth data, with enough accuracy is seldom available. Isolation forest is the unsupervised anomaly detection approach adopted in this work. This method is based on characterizing anomalous traffic conditions by exploiting the fact that anomalies tend to be isolated. The most remarkable feature of this anomaly detection method is its high detection performance while having a very simple tuning procedure and an extremely low computational demand. Finally, the effectiveness of the presented AID method is demonstrated using real traffic data collected by a network of Bluetooth sensors installed in Ayalon Highway, Tel Aviv.

Cost-effectiveness analyses demonstrate that observation is superior to sentinel lymph node biopsy for postmenopausal women with HR + breast cancer and negative axillary ultrasound.

PURPOSE: To evaluate the cost-effectiveness of axillary observation versus sentinel lymph node biopsy (SLNB) after negative axillary ultrasound (AUS). In patients with clinical T1-T2 N0 breast cancer and negative AUS, SLNB is the current standard of care for axillary staging. However, SLNB is costly, invasive, decreasing in importance for medical decision-making, and is not considered therapeutic. Observation alone is currently being evaluated in randomized clinical trials, and is thought to be non-inferior to SLNB for patients with negative AUS. METHODS: We performed cost-effectiveness analyses of observation versus SLNB after negative AUS in postmenopausal women with clinical T1-T2 N0, HR+/HER2- breast cancer. Costs at the 2016 price level were evaluated from a third-party commercial payer perspective using the MarketScan® Database. We compared cost, quality-adjusted life years (QALYs), and net monetary benefit (NMB). Multiple sensitivity analyses varying baseline probabilities, costs, utilities, and willingness-to-pay thresholds were performed. RESULTS: Observation was superior to SLNB for patients with N0 and N1 disease, and for the entire patient population (NMB in US$: $655,659 for observation versus $641,778 for SLNB for the entire patient population). In the N0 and N1 groups, observation incurred lower cost and was associated with greater QALYs. SLNB was superior for patients with > 3 positive lymph nodes, representing approximately 5% of the population. Sensitivity analyses consistently demonstrated that observation is the optimal strategy for AUS-negative patients. CONCLUSION: Considering both cost and effectiveness, observation is superior to SLNB in postmenopausal women with cT1-T2 N0, HR+/HER2- breast cancer and negative AUS.

Cortical Observation by Synchronous Multifocal Optical Sampling Reveals Widespread Population Encoding of Actions.

To advance the measurement of distributed neuronal population representations of targeted motor actions on single trials, we developed an optical method (COSMOS) for tracking neural activity in a largely uncharacterized spatiotemporal regime. COSMOS allowed simultaneous recording of neural dynamics at ∼30 Hz from over a thousand near-cellular resolution neuronal sources spread across the entire dorsal neocortex of awake, behaving mice during a three-option lick-to-target task. We identified spatially distributed neuronal population representations spanning the dorsal cortex that precisely encoded ongoing motor actions on single trials. Neuronal correlations measured at video rate using unaveraged, whole-session data had localized spatial structure, whereas trial-averaged data exhibited widespread correlations. Separable modes of neural activity encoded history-guided motor plans, with similar population dynamics in individual areas throughout cortex. These initial experiments illustrate how COSMOS enables investigation of large-scale cortical dynamics and that information about motor actions is widely shared between areas, potentially underlying distributed computations.

Factors influencing the early initiation of breast feeding in public primary healthcare facilities in Northeast Nigeria: a mixed-method study.

INTRODUCTION: The early initiation of breast feeding is a high-impact intervention that gives newborns a better chance of survival. We assess the barriers and facilitators influencing the practice of early breast feeding of newborns in public primary healthcare facilities (PHCs) in Northeast Nigeria, to influence the planning of programmes targeted at improving newborn care in the region. METHOD: We used an explanatory mixed-method approach. We conducted case observation of childbirths and newborn care for the quantitative arm, and interviewed mothers and birth attendants 1 hour after childbirth for the qualitative arm. The analysis for the quantitative arm was done with SPSS V.23. For the qualitative arm, we transcribed the audio files, coded the texts and categorised them using thematic analysis. RESULT: We observed 393 and 27 mothers for the quantitative and qualitative arms of the study, respectively. The quantitative arm shows that 39% of mothers did not breastfeed their newborns within 1 hour of birth. The qualitative arm shows that 37% of mothers did not breastfeed within 1 hour of birth. Themes that describe the barriers to early breast feeding in public PHCs are: birth attendants' unwillingness or inability to accommodate mothers' safe traditional practices, ineffective rooming-in practices, staff shortages, lack of privacy in the lying-in ward and poor implementation of visiting-hour policy in public PHCs. The pregnant women denied safe traditional birth practices like chanting, praying or reading religious books during delivery are five times more likely not to breastfeed newborns within the first hour of birth (relative risk=4.5, 95% CI 1.2-17.1) compared with pregnant women allowed these practices. CONCLUSION: Stakeholders must increase their focus on improving breastfeeding practices in public PHCs. Instituting policies that protect mothers' privacy and finding innovative ways to accommodate and promote safe traditional practices in the intrapartum and postpartum period in PHCs will improve the early breast feeding of newborns in these PHCs.
