Classroom Versus Computer-based CPR Training: A Comparison of the Effectiveness of Two Instructional Methods
Authors: Rehberg Robb S. , Diaz Linda Gazzillo , Middlemas David A.
Published: June 2020

Objective: The objective of this study was to determine whether computer-based CPR training is comparable to traditional classroom training.

Design and Setting: This study was quantitative in design. Data was gathered from a standardized examination and skill performance evaluation which yielded numerical scores.

Subjects: The subjects were 64 undergraduate freshmen who never had CPR training or performed CPR. The subjects were divided into two groups. Group 1 completed the National Safety Council Adult CPR training program via traditional classroom instruction, while Group 2 completed the online version.

Measurements: After training, both groups completed the standardized knowledge examination and skill performance evaluation. Skill performance was evaluated by trained evaluators and Resusci Anne computerized CPR manikins.

Results: On the standardized knowledge examination and skill performance evaluation, Group 2 scored lower than Group 1; however, no statistically significant difference between the groups existed. MANOVA indicated there was a significant difference in the quality of CPR compressions (location, rate, depth, and release), ventilation rate and volume.

Conclusions: Computer-based CPR training may be as effective as traditional classroom CPR training in terms of knowledge outcomes. However, the computer-based CPR training method may not be as effective as traditional classroom-based training in terms of developing quality CPR performance. These results are critical, as quality of CPR effort performed on a cardiac arrest victim has a direct impact on effectiveness.

Dynamic Paired-Behaviors in Effective Clinical Instruction
Authors: Ford Philip D. , Velasquez Benito
Published: June 2020

Background: Pedagogical strategies related to clinical instruction are needed to improve students' education in the clinical setting.

Description: In this article, we use the relevant literature to identify and define “effective” clinical instructor behaviors in athletic training. In addition, we propose a pairing of behaviors as a cueing strategy for athletic training clinical instructors.

Objective: The purpose of the article is to provide a brief background on the following paired-behaviors: communication-action, demonstration-practice, and instruction-evaluation as key elements to effective clinical instruction in athletic training education.

Educational Advantages: If clinical instructors recognize the importance of using these paired-behaviors in clinical education, it may dramatically impact student learning.
Educational Technology: Using Computer-Based Scenario Authoring Tools in Athletic Training
Authors: Wagner Ronald
Published: June 2020

Column Editor's Note:

Welcome to the inaugural issue of the ATEJ Educational Technology Column (ETC). This first issue of the ETC is monumental in that it continues the legacy of the athletic training profession's commitment to educational technology. Educational technology has been a frequent topic in the ATEJ. A quick skim of the ATEJ archive reveals keywords such as DVD, mobile learning, online assessment, web-based database, and computer-based training CPR.

The goal of the ETC is to provide a compendium of affordable, easy-to-use, time-saving educational technology tools for the athletic training educator. Each issue of the ETC will be dedicated to a specific theme and paired with a set of tools which can be used by you, the athletic training educator, for teaching, learning and/or administrative purposes. The ETC will provide understandable reviews of the advantages, disadvantages, and practical applications for each tool. A typical column will provide a hypothetical problem and technology tool solution. The ultimate goal of the ETC is to provide solutions to real problems faced by educators while saving you time, money, and frustration that often accompanies the process of finding the right technology solution.
Perceived Preparedness of Graduate Assistant Approved Clinical Instructors for Supervision of Athletic Training Students in Professional Programs
Authors: Pircher Christopher M. , Sandrey Michelle A. , Erickson Mia
Published: June 2020

Context: Approved clinical instructors (ACIs) are crucial for the development of athletic training students. Graduate students often serve as ACIs and usually do not have extensive clinical experience, and therefore may not feel adequately prepared to supervise students.

Objectives: 1) To determine the perceived preparedness of graduate assistant ACIs in the supervision of athletic training students in professional programs; 2) To determine perceptions of ACI training.

Design: Prospective, exploratory.

Setting: Programs that have been accredited by the Commission on Accreditation of Athletic Training Education (CAATE) for five years or more.

Participants: Thirty-three out of 140 graduate assistant ACIs (23.5% response rate) at 27 athletic training programs.

Instrumentation: A 47-item Graduate Assistant ACI Perceived Preparedness online questionnaire.

Data Analysis: Frequencies and percentages were used to describe the responses for questionnaire items; an ANOVA was used to examine self-assessment ratings among participant groups.

Results: Participants felt prepared in learning styles (79%), ACI responsibilities (100%), evaluation and feedback of student performance (79%). They felt most prepared to evaluate and provide feedback in students' clinical skills and least prepared in evaluating and providing feedback for professional behaviors. The greatest challenges faced by participants included time constraints (69.7%), controlling the learning environment (57.6%), and understanding institutional policies and procedures related to clinical education (39.4%). When asked to self-assess their first-year performance supervising students on a scale of 0 (worst performance) to 10 (best performance), the mean [SD] score reported was 6.97 [1.2]. There were no differences in first-year self-assessment performance ratings between participants who thought ACI training was adequate and/or beneficial and those who did not (P=0.05).

Conclusion: Most of the participants felt prepared to be an ACI as a graduate assistant and believed the ACI training to be adequate and beneficial. There were no differences in self-reported first-year performance ratings between participants who believed their training to be adequate and beneficial and those who did not.
Career Decisions of Senior Athletic Training Students and Recent Graduates of Accredited Athletic Training Education Programs
Authors: Neibert Peter , Huot Christopher , Sexton Patrick
Published: June 2020

Context: Athletic training students and graduates are faced with many factors that direct them into or away from the athletic training profession as a final career choice.

Objective: The purpose of the study was to determine the career decisions made by athletic training students following graduation from an accredited professional athletic training edcuation program (ATEP) and what work-related and ATEP program factors influenced their career decisions.

Design: A 42-question self-reporting web-based survey was used.

Setting: CAATE/CAAHEP-accredited ATEP programs.

Participants: Seventeen hundred and ninety-two seniors and recent graduates of CAATE/CAAHEP-accredited programs from May 2005 through June 2007.

Outcome Measures: Descriptive statistics were utilized to obtain frequency counts of the participants' responses.

Results: The majority of the participants (82.4%) chose to pursue a career as an athletic trainer (AT), while the remainder (17.6%), indicated they did not seek employment as an AT. The college/university setting was the most frequently selected by those employed (45.6%) and those seeking employment (35.6%) as an AT. All 8 ATEP factors (clinical experience hours, clinical experience variety, roles/functions of a clinical instructor [CI] or approved clinical instructor [ACI], preparation to enter the field, level of confidence, CI or ACI attitude toward work setting, CI or ACI demonstration of professionalism, and encouragement from faculty, CI or ACI) were found to be influential in the participants' decisions to pursue a career as an AT. Salary, number of work hours per week, found another profession more interesting, and uncertain or changing work schedule were the most influential factors reported for choosing to not pursue a career as an AT.

Conclusions: The decision to pursue a career as an AT is influenced by ATEP faculty, ACIs, and CIs.
Current Literature Summary

Continuing education is mandatory to maintain BOC certification; however, there is a void in athletic training research regarding its efficacy in maintaining or enhancing professional competence. Presumably, one acquires new knowledge by attending continuing education programs. Hopefully this new knowledge is retained and translated into professional practice to improve patient care. Other health care professions, particularly nursing and medicine, have examined the efficacy of continuing education. We will provide brief synopses of current continuing education research and discuss possible applications to athletic training.

Effect of Performance Feedback on Perceived Knowledge and Likelihood to Pursue Continuing Education
Authors: Eberman Lindsey E. , Tripp Brady L.
Published: June 2020

Context: For practicing health care professionals, waiting for a teachable moment to identify a gap in knowledge could prove critical. Other methods are needed to help health care professionals identify their knowledge gaps.

Objective: To assess the effect of performance feedback on Athletic Trainers' (AT) perceived knowledge (PK) and likelihood to pursue continuing education (CE).

Design and Setting: Pre-test, post-test control-group design to measure PK and likelihood to pursue CE before and after assessing actual knowledge (AK) in an on-line classroom (Campus Edition 6; Blackboard Inc.).

Participants: We randomly sampled potential participants (n = 2000) from the National Athletic Trainers' Association membership directory and then randomly assigned (n = 103/2000, 5.1%) them to control (n = 58) or experimental groups (n = 45).

Interventions: Performance feedback following the AK assessment in the experimental group.

Main Outcome Measures: We assessed PK and likelihood to pursue CE before and after the AK assessment. We calculated differences between pre-test and post-test scores and knowledge gap. Two independent samples t-tests examined the effects of feedback on the dependent measures. Multiple linear regression was used to predict post-test likelihood to pursue CE using three variables: PK, pre-test likelihood to pursue CE knowledge gap.

Results: We found a significant difference (68.2%) between groups for likelihood to pursue CE (P = 0.01, ES = 0.45). The experimental group demonstrated a 13.8% (pre-test = 4.12 ± 1.32, post-test = 4.78 ±1.13) increase in likelihood to pursue CE, while the control group increased 4.4% (pre-test = 4.60 ± 1.07, post-test = 4.81 ± 1.08). Pre-test likelihood to pursue CE was a significant predictor of post-test likelihood to pursue CE (r = 0.74, R2= 0.55, P = 0.05). We observed a moderate relationship between pre-test knowledge gap and post-test likelihood to pursue CE (r = 0.31, R2= 0.10, P < 0.01). Pre-test knowledge gap was a significant predictor of post-test knowledge gap(r = 0.88, R2=0.77, P < 0.01).

Conclusions: Knowledge assessment alone increases the likelihood to pursue CE, yet when feedback is provided ATs are more likely to pursue CE.

Groundwater wells in Triassic sediments of Dong Giao formation in Kien Khe, Hanam include 6 wells in an area of 4km2. To evaluate the ability of sustainable exploitation, meeting the demand of water supply, the scientific calculation is very important and necessary. This layer is rich in water, good quality, meeting large water supply requirements. However, if the regime and volume of exploited water cannot be determined, it may cause degradation, depletion or change of water quality of the reservoir.
In order to have a scientific basis for exploitation, we have conducted exploration with many types of work (field surveys, geophysical measurements, exploratory drilling, water absorption experiments, sampling analysis, calculation , synthesis of assessment and design of exploitation). Calculation results show that the exploitation of 6 wells with the flow of 1,500m3/day in the study area is reasonable, safe, meeting the requirements of both volume and quality for water supply and sustainable development.

Urbanization is taking place at an unprecedented rate around the world, particularly in Vietnam. One of the key impacts of rapid urbanization on the environment is the effect of urban heat island (UHI). Understanding the effects of landscape pattern on UHI is crucial for improving the ecology and sustainability of cities. This study investigated how landscape composition and conﬁguration would affect UHI in the District 7, Ho Chi Minh City of Vietnam, based on the analysis of land surface temperature (LST) in relation to the percentage of vegetation, impervious, and water surface. Landsat 8 OLI satellite images acquired on February 14th, 2017 was used to estimate the LST from the thermal channel, while the percentage of vegetation, impervious, and water surface were extracted from multi-spectral channels. Our results indicate that there is a significant difference in LST among the wards in the study area. Impervious surfaces contribute the most to UHI, followed by bare soil, vegetative cover, and water. The research results also show that the structure of urban coverings should reach: 50% of impermeable surfaces and bare land, the remaining 50% are water and vegetation. These results are useful for understanding urban ecology as well as land use planning to minimize the potential environmental impacts of urbanization.

Although the statistics and land inventory from 2014 up to now have made much progress, the Natural Resources and Environment sector, as well as many production units, have put in application some software and supporting tools such as TK2015, gCadas, VietMap XM, TKDesktop 2019, etc. However, these software are mainly manual or semi-automatic, not organized to comply with database standards, while the control of the additional investigation, data editing, must be manipulated, updated many times, so the application of the above software in reality still faces many difficulties and expensive. In order to effectively and synchronously perform land statistics and inventory, additional studies and proposals for scientific and technological improvement are necessary. This article presents a new approach for the purpose of thorough automation in land statistics and inventory based on proposing effective implementation solutions and building statistical databases and land inventory according to current regulations.

MPPT Controller for PV Array under Partially Shaded Condition
Authors: BADOUD Abd Essalam
Published: June 2020

The output power of the Photovoltaic system having multiple arrays is reduced to a great extent when it is partially shaded due to environmental hindrances. Conventional popular MPPT methods are effective under uniform solar irradiance. However, under partially shaded conditions, these MPPTs can fail to track the real MPP because of the multiple local maxima which can be existed on PV characteristic curve under partially shaded condition. This paper reports the development of a maximum power-point tracking method for photovoltaic systems under partially shaded conditions using bond graph. The major advantages of the proposed method are simple computational steps, faster convergence, and its implementation on a low-cost microcontroller. The performance of proposed MPPT is analyzed according to the position of real MPP. Simulation results have been contrasted with real measured data from a commercial PV module of Photowatt PW1650.

Redes agroalimentares alternativas e consumo crítico: o caso das feiras orgânicas de Porto Alegre
Authors: Martil Graciela Cristina Dillemburg , Anjos Flávio Sacco dos
Published: June 2020

As quatro últimas décadas coincidem com a aparição do que se convencionou chamar “redes agroalimentares alternativas”. Os inúmeros escândalos, a incerteza generalizada e a busca por alimentos mais saudáveis figuram em destaque, dentro de um movimento mais amplo denominado “turn of quality”, onde a ideia de qualidade ultrapassa os atributos estritos e tangíveis do produto. As feiras orgânicas de Porto Alegre se inserem dentro das transformações que incidem sobre o mundo da alimentação em geral. O foco do estudo é elucidar as circunstâncias que contribuíram para o seu surgimento, assim como as mutações que esse sistema local de abastecimento experimenta desde o seu surgimento. A pesquisa busca mostrar que as feiras orgânicas consistem num espaço social singular onde operam muito mais do que operações de compra e venda de alimentos. Não obstante, há desafios em relação ao futuro, especialmente os desdobramentos decorrentes do incremento da demanda e risco de convencionalização.
Republicanismo e cristianismo: dilemas de uma relação problemática
Authors: Trindade Gleyton , Cerveira Sandro
Published: June 2020

Autores como Pocock, Skinner e Pettit têm revalorizado o republicanismo como tradição política fundamental na constituição do mundo moderno em contraste com a hegemonia da tradição liberal. Este trabalho pretende analisar aquela que tem sido caracterizada como uma relação das mais problemáticas e desafiadoras para os republicanos: a relação entre republicanismo e cristianismo. Argumentamos que a dificuldade na análise das relações entre republicanismo e cristianismo deriva das próprias dificuldades do projeto neorrepublicano em delimitar o republicanismo como tradição política específica. A superação de tais dilemas envolveria uma melhor qualificação da tradição republicana incluindo os temas da comunidade política como "comunidade universal", uma concepção não instrumental da vida pública e o reconhecimento de que a concepção da liberdade como não dominação implica que as instituições republicanas promovem determinados valores.

Published: June 2020

A inclusão escolar de alunos com deficiência abarca múltiplas variáveis, personagens e contextos. Esse estudo analisou a inclusão em aulas de Educação Física de uma escola regular do Mato Grosso do Sul, Brasil, a partir do modelo bioecológico. Desenvolveu-se um estudo de caso por observação de 15 aulas de Educação Física de uma turma do 3° ano do ensino fundamental, que possuía uma aluna com deficiência. Para coleta de dados, utilizou-se o “Instrumento de avaliação da interação entre alunos com e sem deficiência na educação física escolar”, com dados apreciados por categorização. O sistema escolar tem se adaptado para atuar conjuntamente ao familiar e cultural, de forma consonante às promulgações políticas. Houve aspectos favoráveis ao processo inclusivo - interações positivas e participação ativa dos alunos -, entremeados por dificultadores - fragilidades na acessibilidade arquitetônica. A inclusão na Educação Física Escolar pode ser facilitada pela compreensão da complexidade dos aspectos abarcados.

Authors: Bungenstab Gabriel Carvalho
Published: June 2020

Este artigo procura compreender como se dá a presença do termo “juventude” na produção científica da Educação Física (EF) brasileira. Para responder a essa indagação, num primeiro momento, o texto apresenta o debate a respeito da condição juvenil, discutindo a presença dos projetos de escolarização nesse seio. Feito isso, realiza uma revisão de literatura, em termos de artigos científicos, nas principais revistas do campo da Educação Física brasileira. A partir dos resultados, notou-se que ainda é incipiente a participação do campo científico da EF no debate sobre o conceito de juventude. Contudo, a produção do campo começa a entender que as práticas corporais e esportivas são fundamentais para a compreensão de sociabilidades juvenis, sobretudo, na constituição das múltiplas identidades dos jovens.

Aplicação de Zeólitas na Purificação de Biogás: Desafios e Possibilidades
Authors: Filho José Demontier , Rollemberg Silvio , Lima Ari
Published: June 2020

A crescente produção de resíduos sólidos urbanos (RSU) representa um sério problema ambiental. A matéria orgânica, presente nos RSU, sofre digestão anaeróbia, nos aterros sanitários, produzindo uma mistura gasosa: o biogás de aterro. Estima-se que cerca de 45% a 55% do biogás de aterros sanitários é formado por metano (CH4). O dióxido de carbono (CO2), como produto da digestão anaeróbia, necessita ser removido para elevação do poder calorífico do biogás extraído. Cerca de 35% do biogás de aterro é formado CO2 e a remoção deste pode ser realizada por meio da técnica de adsorção. A vantagem da adsorção frente a outras técnicas se dá pelo baixo custo operacional, a elevada eficiência de separação e facilidade acerca de seu manuseio. Para o emprego da adsorção como mecanismo de purificação de biogás de aterro sanitário, fez-se o uso de zeólitas. Um desafio no que tange ao emprego de zeólitas é a possibilidade de utilização em largas escalas. Para oportunizar circunstâncias futuras, adotou-se zeólita 4A – tendo sido previamente caracterizada por meio de MEV (Microscopia Eletrônica de Varredura) e DRX (Difração de Raios-X) – para purificação de biogás presente no Aterro Sanitário Metropolitano Oeste de Caucaia (ASMOC). A zeólita 4A mostrou-se seletiva para CH4 em relação a CO2. As remoções de CO2 foram aumentadas quando se elevou a massa de zeólita 4A no mecanismo de purificação.

Published: June 2020

BACKGROUND:

Health-care workers (HCW) are susceptible to latent tuberculosis infection (LTBI). The prevalence of LTBI in HCW in Saudi Arabia has not been reported using the fourth-generation interferon gamma release assay QuantiFERON-TB Gold Plus (QFT-Plus).

OBJECTIVE:

Determine the prevalence of LTBI in a large heterogeneous HCW population and assess risk factors for LTBI.

DESIGN:

Cross-sectional and case-control study.

SETTING:

Tertiary academic hospital, Riyadh, Saudi Arabia.

PATIENTS AND METHODS:

Medical records of HCWs who had QFT-Plus performed between January to December 2018 were reviewed and included in the cross-sectional study. In a subset analysis, randomly selected positive QFT-Plus cases were compared with controls selected from the same areas of work. Univariate and binary logistic regression analyses were performed to assess the significance of other factors to QFT-PLus positivity.

MAIN OUTCOME MEASURES:

Prevalence of LTBI in HCWs and potential risk factors for LTBI.

SAMPLE SIZE:

3024 HCWs in the cross-sectional analysis; 294 cases and 294 controls in the case-control analysis.

RESULTS:

Twenty-four percent (n=733) of the HCWs had a positive QFT-Plus. The median (interquartile range) age was 34.0 (31.0-37.1) years, 71% were female, and only 24.8% were of Saudi nationals. Nursing represented 57.7% of HCWs, and 24.7% were working in a non-clinical area. Only 20.3% worked in TB-related departments. A higher risk of LTBI was present in HCWs who were older than 50 years (OR=1.95), from either Philippines (OR=4.7) or the Indian subcontinent (OR=4.1), working as a nurse (OR=2.7), allied health profession (OR=2.1), radiology technician (OR=3.1), or in the emergency room (OR=2.4) or intensive care unit (OR=2.1). In the binary logistic regression, independent predictors for positive QFT-Plus were age group older than 50 years (aOR=2.96), known TB exposure (aOR=1.97), and not receiving BCG at birth (aOR=3.08).

LIMITATION:

Single-center, retrospective, possible recall bias for BCG vaccination.

CONCLUSION:

The high prevalence of LTBI among HCW emphasizes the need to continue pre-employment screening, especially for employed personnel from high endemic areas, with targeted annual screening for the same group and other identified high-risk groups. These findings can aid in the development of national screening guidelines for LTBI in HCW.

Published: June 2020

BACKGROUND:

Data on long-term survival and recurrence of cancer after complete mesocolic excision (CME) for colon cancer has not been reported from our center and related to international data.

OBJECTIVE:

Describe overall and disease-free survival, survival by surgery site and stage, and recurrence rates after curative surgery.

DESIGN:

Retrospective chart review.

SETTINGS:

Academic tertiary care center.

PATIENTS AND METHODS:

The study included all patients who underwent either laparoscopic or open surgery for colon cancer with curative intent between 2001 and 2011. The colorectal database was reviewed for the following: demographic data, comorbidities, radiologic investigations, clinical stage, type of operation, complications, pathologic assessment, adjuvant treatment, recurrence and survival. Survival and recurrence rates were calculated, and survival curves were generated.

MAIN OUTCOME MEASURES:

5-year overall survival, secondary endpoints were 5-year disease-free survival, survival by surgery site and stage, and recurrence rates.

SAMPLE SIZE:

220.

RESULTS:

The mean (SD) age at diagnosis was 57 (13) years (CI 95%: 55-59 years). There were 112 males. Mean (SD) body mass index was 27.6 (5.7) kg/m2(CI 95%: 27-28). Pathological assessment revealed R0 (microscopically margin-negative) resection in 207 (94%). The overall 5-year survival and disease-free survival was 77.9% and 70%, respectively. The 5-year disease-free survival was 69% for the sigmoid/left colon and 69% for the right colon (difference statistically nonsignificant). Stages at the time of resection were stage 0 for 2 (0.01%) patients, stage I for 18 (8%), stage II for 92 (42%), stage III for 100 (46%), and stage IV for 6 (3%). The 5-year overall survival by stages I, II, III and IV was 94%, 80%, 75% and 50%, respectively (difference statistically non-significant). The overall 5-year recurrence rate was 23.4%.

CONCLUSION:

The outcomes of surgical treatment for colon cancer at our institution are equivalent to international sites. No difference was noted between left and right colon in terms of survival after CME.

LIMITATIONS:

Single center, retrospective, small sample size.

Abstract. The application of regional-scale air quality models is an important tool in air quality assessment and management. For this reason, the understanding of model abilities and performances is mandatory. The main objective of this research was to investigate the spatial and temporal variability of background particulate matter (PM) concentrations, to evaluate the regional air quality modelling performance in simulating PM concentrations during statically stable conditions and to investigate processes that contribute to regionally increased PM concentrations with a focus on eastern and central Europe. The temporal and spatial variability of observed PM was analysed at 310 rural background stations in Europe during 2011. Two different regional air quality modelling systems (offline coupled European Monitoring and Evaluation Programme, EMEP, and online coupled Weather Research and Forecasting with Chemistry) were applied to simulate the transport of pollutants and to further investigate the processes that contributed to increased concentrations during high-pollution episodes. Background PM measurements from rural background stations, wind speed, surface pressure and ambient temperature data from 920 meteorological stations across Europe, classified according to the elevation, were used for the evaluation of individual model performance. Among the sea-level stations (up to 200 m), the best modelling performance, in terms of meteorology and chemistry, was found for both models. The underestimated modelled PM concentrations in some cases indicated the importance of the accurate assessment of regional air pollution transport under statically stable atmospheric conditions and the necessity of further model improvements.

Abstract. Source-specific optical properties of light-absorbing carbonaceous (LAC) aerosol are poorly understood owing to its various sources in the atmosphere. Here, a receptor model coupling multi-wavelength absorption with chemical species was utilized to explore the source-specific LAC optical properties at a tropical marine monsoon climate zone. Results showed that biomass burning contributed the largest to LAC absorption on average, but ship emissions became the dominant contributor (44–45 %) when the air masses originated from the South China Sea. The source-specific absorption Ångström exponent indicates that black carbon (BC) was the dominant LAC aerosol in ship and motor vehicle emissions while there was also brown carbon (BrC) existed in biomass-burning emissions. The source-specific mass absorption cross section (MAC) showed that BC from ship emissions had a stronger light-absorbing capacity than biomass burning and motor vehicle emissions. The BrC MAC derived from biomass burning was smaller than BC MAC and highly depended on wavelengths. Radiative effect assessment indicates a comparable atmospheric forcing and heating capacity of LAC aerosol from biomass burning and ship emissions. Our study provides insights into the optical properties of LAC aerosol from various sources and can improve our understanding of the LAC radiative effects caused by ship emissions.

Abstract. The development of fast-response analysers for the measurement of nitrous oxide (N2O) has resulted in exciting opportunities for new experimental techniques beyond commonly used static chambers and gas chromatography (GC) analysis. For example, quantum cascade laser absorption spectrometers (QCL) are now being used with eddy covariance (EC) or automated chambers. However, using a field-based QCL EC system to also quantify N2O concentrations in gas samples taken from static chambers has not yet been explored. Gas samples from static chambers are commonly analysed by GC that often requires labour and time consuming procedures off-site. Here, we developed a novel, field-based injection technique that allowed the use of a single QCL for: (1) micrometeorological EC; and (2) immediate manual injection of headspace samples taken from static chambers. To test this approach across a range of low to high N2O fluxes, we applied ammonium nitrate (AN) at 0, 300, 600 and 900 kg N ha−1 (AN0, AN300, AN600, AN900) to plots on a pasture soil. After analysis, calculated N2O fluxes from QCL (FN2O_QCL) were compared with fluxes determined by a standard method, i.e. here laboratory-based GC (FN2O_GC). Subsequent comparison of QCL and GC derived data was tested using orthogonal regression, Bland Altman and bioequivalence statistics. For the AN treated plots, the mean cumulative N2O emissions across the seven day campaign were 0.97 (AN300), 1.26 (AN600) and 2.00 (AN900) kg N2O-N ha−1 for FN2O_QCL and 0.99 (AN300), 1.31 (AN600) and 2.03 (AN900) kg N2O-N ha−1 for FN2O_GC. These FN2O_QCL and FN2O_GC were highly correlated (r = 0.996, n = 81) based on orthogonal regression, in agreement following the Bland Altman approach (i.e. within ± 1.96 standard deviations of the mean) and shown to be for all intents and purposes the same (i.e. bioequivalent). The FN2O_QCL and FN2O_GC derived under near-zero flux conditions (AN0) were weakly correlated (r = 0.306, n = 27) and not found to agree or to be bioequivalent. This was likely caused by the calculation of small but apparent positive and negative FN2O when in fact the actual flux was zero, i.e. below the detection limit of static chambers. Our study demonstrated (1) that the capability of using one QCL to measure N2O at different scales, including manual injections, offered a great potential to advance field measurements of N2O (and other greenhouse gases) in future; and (2) that suitable statistics have to be adopted when formally assessing the agreement and difference (not only the correlation) between two methods of measurement.
