With its promise of nondestructive processing, rapid low-cost sampling, and portability to any field site or museum in the world, portable X-ray fluorescence (pXRF) spectrometry is rapidly becoming a standard piece of equipment for archaeologists. Even though the use of pXRF is becoming standard, the publication of pXRF analytical methods and the resulting data remains widely variable. Despite validation studies that demonstrate the importance of sample preparation, data collection settings, and data processing, there remains no standard for how to report pXRF results. In this article, we address the need for best practices in publishing pXRF analyses. We outline information that should be published alongside interpretive results in any archaeological application of pXRF. By publishing this basic information, archaeologists will increase the transparency and replicability of their analyses on an inter-analyst/inter-analyzer basis and provide clarity for journal editors and peer reviewers on publications and grant proposals for studies that use pXRF. The use of these best practices will result in better science in the burgeoning use of pXRF in archaeology. [ABSTRACT FROM AUTHOR]

TAXONOMY , *ACOUSTICS , *BIRDSONGS , *DNA sequencing , *DATA libraries - Abstract
A survey of recent taxonomic studies of birds that included acoustic trait analyses reveals that most studies have not archived the sound recordings that support their conclusions, despite the current availability of online, publicly available collections of bird sounds. In addition, bird sound recordings have often been cited without unique accession numbers that permit unambiguous sample identification and in considerably less detail than other types of samples, such as museum specimens or genetic samples. Both this lack of data openness and the way acoustic samples have been cited undermine the methodological rigor that otherwise characterizes many of these studies, and much invaluable biological data are likely to be lost over time if bird sound recordings are not archived in long-term collections. I suggest that these problems can be easily addressed by embracing the open data movement and adopting some best practices that are widely used in other fields. Just as study skins and DNA sequences are required to be deposited in publicly available collections such as natural history museums and the GenBank, respectively, sound recordings used in taxonomic studies with acoustic trait analyses should be archived in publicly available collections as a condition for publication of associated results. Authors of taxonomic studies involving sounds should archive their sound recordings and provide unique accession numbers for sound recordings examined, and journals and reviewers should ensure that authors have done so. By embracing the open data movement, research studying avian acoustic signals is expected to become more transparent, reproducible, and useful. [ABSTRACT FROM AUTHOR]

The number of reproduction and replication studies undertaken across the sciences continues to rise, but such studies have not yet become commonplace in geography. Existing attempts to reproduce geographic research suggest that many studies cannot be fully reproduced, or are simply missing components needed to attempt a reproduction. Despite this suggestive evidence, a systematic assessment of geographers' perceptions of reproducibility and use of reproducible research practices remains absent from the literature, as does an identification of the factors that keep geographers from conducting reproduction studies. We address each of these needs by surveying active geographic researchers selected using probability sampling techniques from a rigorously constructed sampling frame. We identify a clear division in perceptions of reproducibility among geographic subfields. We also find varying levels of familiarity with reproducible research practices and a perceived lack of incentives to attempt and publish reproduction studies. Despite many barriers to reproducibility and divisions between subfields, we also find common foundations for examining and expanding reproducibility in the field. These include interest in publishing transparent and reproducible methods, and in reproducing other researchers' studies for a variety of motivations including learning, assessing the internal validity of a study, or extending prior work.

Abstract Current practices for assembling phylogenetic trees often recur to sequence data stored in GenBank. However, the molecular and taxonomic make‐up of sequences deposited in GenBank is generally not very clear. phruta, a newly developed r package, is designed to primarily improve access to genetic data stored in GenBank. Functions in phruta further enable users to assemble single‐ and multi‐gene molecular datasets, and run basic phylogenetic tasks, all within r. The structure of the functions implemented in phruta aim to allow users to assemble simple workflows for particular tasks, which are in turn expected to increase reproducibility of relatively simple phylogenies. To support the use of phruta by researchers in different fields with variable levels of coding expertise, this paper presents the first version of salphycon, a shiny web app that aims to increase access to the fundamental functions in the phruta r package.

The main purposes of this study were to determine the absolute and relative reliability of two-step test (TST) with a functional electromechanical dynamometer (FEMD) in the evaluation of body displacement velocity. Sixteen physically active male handball players volunteers (age 21.4 ± 2.1 years) participated in this study. A repeated-measurement design was used to evaluate body displacement velocity with 15% and 30% of body weight overload (BWO). The mean velocity of the three highest repetitions and the peak velocity for the concentric contractions were taken to calculate the body displacement velocity. Reliability was assessed by t-tests of paired samples with the effect size (ES), the coefficient of variation (CV), standard error of measurement (SEM), and the intraclass correlation coefficient (ICC), with 95% confidence intervals. The absolute reliability provided stable repeatability for the 15% BWO protocol for mean velocity and for peak velocity in both protocols, with CV being below 10% in nearly all instances. The relative reliability of different velocity protocols to evaluate mean and peak velocity was acceptable (ICCs between 0.48 and 0.79). TST has acceptable reliability for the evaluation of the body displacement velocity in handball players using a FEMD.

Introduction: to reduce the prevalence of overweight and obesity, lifestyle interventions, particularly in nutritional education programs, should be prioritized among university students. Monitoring sedentary behavior is an important step toward preventing and controlling obesity. Therefore, we assessed the reliability and validity of an online questionnaire on sedentary behavior among university students from low-income regions. Methods: this cross-sectional methodological feasibility study evaluated the psychometric properties of the South American Youth/Child Cardiovascular and Environmental (SAYCARE) questionnaire. We administered this questionnaire in an online format to 195 and 117 university students (aged between 17 and 53 years) to assess its validity and reliability, respectively. The questionnaire measures the daily time spent watching TV, playing electronic games, using a computer, studying and passive commuting on weekdays and weekends. The questionnaire involved two stages (Q1 and Q2) separated by an interval of 2 weeks. Reliability was assessed using Spearman's correlation analysis. The structural validity of the construct was evaluated by exploratory factor analysis. Results: all variables showed acceptable reliability (Spearman's rho > 0.30 and p < 0.05). Regarding construct structural validity, the exploratory factor analysis identified 4 factors (variance explained: 71.4 %) and did not exclude any items. Conclusion: the online SAYCARE questionnaire exhibited acceptable reliability and structural validity for assessing sedentary behavior among university students from low-income regions.

The last decade has seen the consolidation of Computational Archaeology and the Digital Humanities as key disciplines in the multifaceted study of historical processes. In this regard, the use of different software packages or programming languages for data analysis has notably increased among archaeologists. However, in many cases open research protocols are not fully observed (when access to data and code are not always granted), which makes reproducibility impossible for other research groups. The present article reviews the transparency of works published in the most important journals of the Iberian Peninsula, to evaluate the degree of openness within the Iberian research community.

The complete and detailed reporting of the search process in systematic reviews is vital for their reproducibility and to evaluate the rigor and reliability of the results. The main objective of this study is to evaluate the transparency and reproducibility of search strategies in systematic reviews published in spanish Library and Information Science journals. For this purpose, the databases Web of Science and Scopus were searched for articles published in these journals identified as systematic or systematized literature reviews. Thirty-five reviews were finally selected and the presence of elements related to the search for information recommended in the PRISMA-S guide was evaluated: complete search strategy, keywords and search terms, time period searched, number of studies retrieved, names of databases searched and limits or filters applied. There are a very deficient reporting of the elements related to the search for information. The majority of the reviews do not provide a complete search strategy and 25 % do not provide keywords either, with the name of the databases searched being the most frequently described element (91,4 %). No differences were found in the information provided in the reviews published by librarians or information professionals and those from other disciplines. Authors using the term systematic or systematized review should describe in a transparent and rigorous manner all the elements essential for its reproducibility and evaluation [ABSTRACT FROM AUTHOR]

- Abstract
Cross-sectional-retrospective study with 120 anteroposterior pelvic radiographs. Eight measurements were taken by three raters in two times to calculate the morphological-cortical (MCI), cortico-metaphyseal (CMI), and cortico-diaphysaire (CDI) indices. Intra/interobserver reproducibility was evaluated with the Bland-Altman method, and hip fracture occurrence was predicted by comparing cut)off points between raters maximizing sensitivity/specificity. The proportion of measurements outside ± 2 SD was similar for diameters/corticals (~5%), but exceeded 1 mm in some corticals, representing 10-20% of distances < 1 cm. Cut)off points fluctuated between 2.45 and 2.53 for MCI (3% difference), between 0.37 and 0.41 for CMI (12% difference), and between 0.23 and 0.33 for CDI (44% difference). [ABSTRACT FROM AUTHOR]

- Abstract
The inter-arm difference (IAD) of systolic blood pressure (SBP) is associated with higher cardiovascular risk. We compared simultaneous and consecutive recordings in measuring IAD of SBP, and evaluated reproducibility between visits. 143 hypertensive patients (63.8±9.5 years, 51.7% women) treated and controlled with stable antihypertensive medication for a period of ≥3 months were included. Blood pressure (BP) in both arms was measured simultaneously and consecutively with an automatic oscillometric device, in two visits. The IAD of the simultaneous SBP was significantly lower compared to the consecutive one, both in the first (3.51±4.1 vs. 4.40±3.7mmHg; P<.01) and in the second visit (3.62±3.5 vs. 5.69±5.1mmHg; P<.001). When the IAD of SBP was categorized as ≥10 or <10mmHg, the reproducibility between visits was insignificant in both simultaneous measurements and consecutive measurements. The frequency of initial dominance was similar between the left and right arm in simultaneous ones (46.2 vs. 43.3%), and greater in the right arm in consecutive ones (55.2 vs. 38.5). The persistence of dominance between both visits was significantly higher when SBP was measured simultaneously (54.4% vs. 45.5%; P<.01). Our study shows that to define the arm with the highest BP, simultaneous measurements are preferable. In treated and controlled hypertensive patients, the poor persistence of initial dominance between visits requires us to review the recommendation of recording, during follow-up, the BP in the arm where it was highest on the first visit., (Copyright © 2024 SEH-LELHA.

- Abstract
Introduction: distal radius fractures are the most common in upper extremities. Therefore, it is important to standardize radiographic measures for their surgical approach. This study assessed the intra/interobserver reproducibility of radiographic parameters associated with surgical success of distal radius fractures. Material and methods: retrospective cross-sectional design of secondary data extracted from clinical records. Posteroanterior and lateral X-rays of 112 distal radius fractures were assessed by two trauma specialists standardized in the measurements required to compute five parameters indicative of postoperative success: radial height, radial inclination, volar tilt, ulnar variance, and articular stepoff. The reproducibility of distances and angles was evaluated using the Bland-Altman method, calculating the mean of the difference between measurements, the range at ± 2 SD, and the proportion of measurements outside ± 2 SD. Postoperative success was also compared between patients with and without obesity according to the mean of the two measures made by each evaluator. Results: evaluator 1 had the largest intra-observer difference in radial height (0.16 mm) and the largest proportion outside ± 2 SD in ulnar variance (8.1%); evaluator 2 had the largest difference in volar tilt (1.92o) and the highest proportion in radial inclination (10.7%). The largest inter-observer difference was for ulnar variance (1.02 mm) and the largest proportion outside ± 2 SD. for radial height (5.4%). Radial tilt had the largest difference (1.41o) with 4.5% of measurements outside ± 2 SD. Ulnar variance and volar tilt had the largest difference in postoperative success between evaluators, especially in patients with obesity. Conclusion: improving the radiographic quality and standardizing the measurements results in more reproducible indicators. [ABSTRACT FROM AUTHOR]

El conocimiento de la anatomía radicular es un factor fundamental en el éxito de un tratamiento de conductos. • Los primeros premolares inferiores están catalogados con un mayor nivel de dificultad en su identificación de la anatomía radiográfica y su tratamiento debido a esta misma complejidad. • La CBCT se considera la técnica radiográfica por elección debido a su validez, pero aun en Colombia de difícil acceso en los servicios de salud tanto públicos como privados. • Las técnicas radiográficas para el uso de radiografías digitales son obligatorias para un buen resultado en la identificación de la anatomía cuando no es posible el uso de la CBCT. Introducción: La existencia de variaciones anatómicas ocasiona fracasos en tratamientos endodónticos, por lo que es importante diagnosticarlas. El objetivo fue determinar la reproducibilidad y la validez de criterio de las radiografías con placa de fósforo y la radiovisografía con sensor para identificar las variaciones anatómicas detectadas por tomografía computarizada de haz cónico (CBCT) en premolares inferiores. Métodos: En 140 premolares se obtuvieron imágenes por CBCT, radiografía y radiovisografía. Se realizó lectura independiente por dos endodocistas, evaluándose la clasificación de Vertucci y las ramificaciones. Se determinó la reproducibilidad intraobservador e interobservador. Se calcularon sensibilidad, especificidad y áreas bajo la curva operador-receptor (AUC) utilizando como estándar de oro la CBCT. Resultados: La reproducibilidad intraobservador e interobservador fue mayor para radiografía. Para la Clase I de Vertucci, la radiografía presentó mayor sensibilidad (94,7%), especificidad (64,9%) y AUC (0,795) que la radiovisiografía (89,3%, 62,2% y 0,757, respectivamente), al igual que para la Clase V (Radiografía 69,2%, 93% y 0,811; Radiovisiografía 50%, 84,2% y 0,671, respectivamente).

Introduction: Considering that the existence of anatomical variations causes endodontic treatment failures, therefore it is important to diagnose them. This study aimed to determine the reproducibility and criterion validity of phosphor plate radiographs and sensor-based radiovisiography to identify anatomical variations detected by cone-beam computed tomography (CBCT) in lower premolars. Materials and Methods: 140 premolars images were obtained by CBCT, radiographs and radiovisiography. Independent interpretation was performed by two endodontists to evaluate the Vertucci classification and ramifications. Intraobserver and interobserver reproducibility were determined. Sensitivity, specificity and areas under the receiver-operator curve (AUC) were calculated using CBCT as the gold standard. Results: Intraobserver and interobserver reproducibility was higher for radiography. For Vertucci type I, radiography showed higher sensitivity (94.7%), specificity (64.9%) and AUC (0.795) than radiovisiography (89.3%, 62.2% and 0.757, respectively), similarly for type V (radiography at 69.2%, 93% and 0.8111; radiovisiography at 50%, 84.2% and 0.671, respectively). None of the techniques contributed to the diagnosis of type III (AUC < 0.5). Ramifications were infrequent (2.9%) with a low level of detection (sensitivity at 25% for radiography and 0% for radiovisiography). Discussion: This is the first study to evaluate the reproducibility and validity of these two radiographic techniques compared with CBCT for the detection of anatomical variations in teeth. Conclusions: Phosphor plate radiography showed higher reproducibility and validity for the diagnosis of Vertucci types I and V, which were the most frequent premolar variations found. This is a dissertation for the Master's degree in Dentistry available in the repository of the Universidad Santo Tomas, Bucaramanga campus. [ABSTRACT FROM AUTHOR]

- Abstract
Introduction: Since the field of dermatopathology is not an exact science, it is subject to personal subjectivity, which sometimes causes disagreements on the diagnosis and assessment of some histological features. In the case of melanoma, some variables such as regression are associated with low interobserver agreement. On the contrary, other variables such as the measurement of Breslow thickness show high reproducibility., Objective: The main objective of our study was to investigate multiple features of 60 consecutive cases of melanoma to establish interobserver reproducibility., Methods and Main Results: We conducted an observational and descriptive study at Hospital de Manises, Valencia, Spain, IVO Foundation, Valencia, Spain, and Hospital 12 de Octubre, Madrid, Spain. The mean level of agreement of all study variables was moderate (Cohen's kappa coefficient statistic=0.5). The highest agreement corresponded to polypoid morphology, pigmentation, ulceration, and solar elastosis. On the other hand, the lowest level agreement was reached for the presence of cellular pleomorphism and tumor necrosis., Conclusions: Our mean level of agreement was moderate, which reflects that some of the measured characteristics such as cellular pleomorphism or the presence of necrosis cannot be used for future studies or must be redefined and their reproducibility, reestablished. When conducting a research study, it is necessary to analyze the study variables to demonstrate their validity to measure or classify a certain feature. It is also advisable to warrant that that the variables are reproducible to be able to use them for other studies or in the routine clinical practice., (Copyright © 2024 AEDV.

Data used to calculate biodiversity indicators may be empirical data (e.g., field data) or modeled outputs (e.g., modeled climate projections). Others have focused on approaches for managing and capturing the myriad of uncertainties in biodiversity indicators stemming from uncertainty in data when based on expert knowledge (Hemming et al. 2017), measurement error (Mason et al. 2018), data bias or data paucity (Giljohann et al. 2018), the benchmark year chosen (Gregory et al. 2019), and uncertainty in composite indicators (Burgass et al. 2017).

- Abstract
In recent years, an increasing number of studies adopting the experimental method have appeared in Public Administration journals. It has been argued that the advantage of experiments in behavioral sciences is that researchers can control contextual factors while investigating the effect of manipulations on a variable of interest. Another point is that experiments can be replicated and, thus, increase confidence in research results. However, replications are rarely undertaken, especially in the behavioral sciences. This article examines the results of the "Open Science Reproducibility Project: Psychology," which replicated 100 experiments previously published in leading Psychology journals. Based on the findings of this project, we present seven recommendations to Public Administration scholars that can improve the quality of their experiments. [ABSTRACT FROM AUTHOR]

Introduction: Introduction: studies of the impact of diet on the prevention and occurrence of diseases in all life stages require a reliable and valid dietary assessment tool for assessing dietary intake. Objectives: this study aimed to develop and evaluate the relative validity and reproducibility of a culturally sensitive quantitative food frequency questionnaire (FFQ) to assess food group intake among Jordanian children and adolescents. Methods: the validation study was carried out on 136 children and adolescents aged between 6 and 18 years who enrolled from selected public and private schools. Fifty of these children and adolescents participated in the reproducibility phase. Food group intake from a quantitative FFQ was compared with food group intake from 24-hour dietary recalls (24h-DRs). Four 24-HRs were collected weekly for one month. Results: intraclass correlation coefficients between the two FFQs ranged from 0.18 for nuts to 0.98 for tea. De-attenuated and energy-adjusted correlations ranged from 0.08 for nuts to 0.95 for vegetable oils. On average, 46.6 % and 43.6 % of participants were ranked by the FFQ-1 and the 24h-DRs into the same quartile based on their crude and energy-adjusted food group intake, respectively. Bland-Altman plots showed a satisfactory agreement between the two methods for milk and milk products and vegetables. Conclusions: the findings of this study suggested that the developed FFQ has excellent reproducibility and good relative validity for most food groups. [ABSTRACT FROM AUTHOR]- Published

The availability and use of geographic information technologies and data for describing the patterns and processes operating on or near the Earth's surface have grown substantially during the past fifty years. The number of geographic information systems software packages and algorithms has also grown quickly during this period, fueled by rapid advances in computing and the explosive growth in the availability of digital data describing specific phenomena. Geographic information scientists therefore increasingly find themselves choosing between multiple software suites and algorithms to execute specific analysis, modeling, and visualization tasks in environmental applications today. This is a major challenge because it is often difficult to assess the efficacy of the candidate software platforms and algorithms when used in specific applications and study areas, which often generate different results. The subtleties and issues that characterize the field of geomorphometry are used here to document the need for (1) theoretically based software and algorithms; (2) new methods for the collection of provenance information about the data and code along with application context knowledge; and (3) new protocols for distributing this information and knowledge along with the data and code. This article discusses the progress and enduring challenges connected with these outcomes. [ABSTRACT FROM AUTHOR]

This article situates the current discussion of reproducibility and replicability taking place across the sciences within geographers' enduring discussion of nomothetic and idiographic approaches, best exemplified by the Hartshorne–Schaefer debate. Although the Hartshorne–Schaefer debate retrospectively set the stage for the development of geography from the 1950s to the present, it is surprising that direct discussions of reproducibility and replicability remain mostly absent from the geographic literature. Drawing from recent literature on reproducibility and replicability in the humanities and physical, social, and computational sciences, it is argued that a deeper focus on these issues will have varied impacts on the discipline. Adopting and improving reproducible practices in geographic research reliant on scientific methods will align geographic research with mainstream scientific inquiry. The discipline's ever-growing diversity of theoretical perspectives and problem domains also makes it likely that a significant portion of geographic research, like many other fields in science, might not be affected by the issues and concerns of reproducibility and replicability. Moving forward, geographic research might continue to benefit from a pluralist framework that embraces both the nomothetic and idiographic approaches, particularly in a broader research environment increasingly defined by disciplinary synthesis and convergence.

OBJECTIVE: To assess the reproducibility of peripapillary, optic nerve head (ONH-PP) and macular vessel density (VD) by Spectral Domain optical coherence tomography angiography (SD OCT-A) in glaucoma patients and healthy subjects. METHODS: Cross-sectional study assessing 63 eyes of 63 subjects, including 33 glaucoma patients and 30 healthy subjects. Glaucoma was classified in mild, moderate, or advanced. Two consecutive scans were acquired by Spectralis Module OCT-A (Heidelberg, Germany), and provided images of the superficial vascular complex (SVC), nerve fiber layer vascular plexus (NFLVP), superficial vascular plexus (SVP); deep vascular complex (DVC), intermediate capillary plexus (ICP) and deep capillary plexus (DCP). VD (%) was calculated by AngioTool. Intraclass correlation coefficients (ICCs) and coefficients of variation (CV) were calculated. RESULTS: Among ONH-PP VD, better ICC presented advanced (0.83-0.97) and moderate glaucoma (0.86-0.96) compared with mild glaucoma (0.64-0.86). For the macular VD reproducibility, ICC results for superficial retinal layers were better for mild glaucoma (0.94-0.96) followed by moderated (0.88-0.93) and advanced glaucoma (0.85-0.91), and for deeper retinal layers ICC was better for moderate glaucoma (0.96-0.95) followed by advanced (0.80-0.86) and mild glaucoma (0.74-0.91). CVs ranged from 2.2% to 10.94%. Among healthy subjects, ICCs for the ONH-PP VD measurements (0.91-0.99) and for the macular VD measurements (0.93-0.97) were excellent in all layers, with CVs from 1.65% to 10.33%. CONCLUSIONS: SD OCT-A used to quantify macular and ONH-PP VD showed excellent and good reproducibility in most layers of the retina, both in healthy subjects and in glaucoma patients regardless of the severity of the disease.

El papel del modelado estadístico en la gestión de emergencias es fundamental para perfilar o apoyar las decisiones en torno a la atención de los eventos. En 2020 con el surgimiento de la pandemia por coronavirus, los países rápidamente se prepararon para la atención del comportamiento de contagio y el impacto que tendría en la salud pública. En Costa Rica, un equipo de especialistas preparó estudios sobre el comportamiento de la curva de contagio y su efecto en la ocupación de camas hospitalarias durante los primeros tres meses de la presencia de la epidemia. Los estudios se basaron en la estimación de modelos estadísticos de crecimiento exponencial y logístico, los cuales proporcionaron los pronósticos del número de casos diarios y acumulados. La predicción de casos permitió alimentar un modelo de simulación para la proyección de demanda de camas hospitalarias por pacientes de la COVID-19. Los análisis se basaron en los datos aportados por el Ministerio de Salud en torno a los casos confirmados por coronavirus desde la aparición del primer caso en Costa Rica. Se estimaron cuatro modelos: logístico, Richards, Gompertz y exponencial, los cuales generaron la predicción de casos diarios. También se estimó el número de reproducibilidad mediante estadística bayesiana para cuantificar la transmisibilidad del virus. Los resultados permitieron anticipar el comportamiento inicial del virus en Costa Rica y el potencial efecto de las medidas de contención que se adopta-ron a partir de la declaratoria de emergencia nacional.

- Abstract
Introduction: Introduction: food intake records are a useful resource for diet assessment, as well as for self-evaluation, self-control, and self-motivation to change an eating behavior. New technologies based on mobile phones permit a different way of recording food intake. Objective: to validate and assess food photographic record (FPR) as a useful instrument in professional practice for assessing food intake. Methodology: forty nutrition professionals participated. In a first stage, food variables obtained through FPR were analyzed and correlated with data from the frequency of food consumption questionnaire (FFQ) and a 24-hour recall (24HR). In a second stage, FPR was applied again to evaluate temporal stability (FPR 1 versus FPR 2). Wilcoxon's test and Spearman's correlation test were applied. Results: a moderate and significant positive association was found for total caloric intake (TCI) and total fat between FPR and 24HR (r = 0.68, p = 0.0008, and r = 0.52, p = 0.01, respectively). In addition, a positive and moderate association was found for TCI, proteins and fats between FPR 1 and FPR 2 (r = 0.61, p = 0.0004; r = 0.60, p = 0.0005; r = 0.64, p = 0.0002, respectively). Conclusion: FPR is a valid method for professional practice to estimate dietary intake, with greater consistency with 24HR data than FFQ, and presents temporal stability for TCI, protein and fat recordings. In addition, FPR may facilitate the adoption of positive eating habits such as more conscious intakes, among other benefits. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Introduction: Excellence in university higher education implies a permanent link with external institutions that serve as practice scenarios for their students. Despite this, in Colombia, there are no investigative processes available for the evaluation and perception of these institutions in the process of university professional practices. Objective: To evaluate the professional practices of Industrial and Environmental Microbiology (IEM) from the perspective of external institutions that participate in the training process, Medellín Colombia, 2009-2017. Methods: Two hundred and eighty-six evaluations carried out by representatives (practice facilitators) of external professional practice institutions were analyzed during 15 student cohorts. A rubric with eleven criteria was designed and validated to evaluate three dimensions of professional practice: Programming, Administration - Management and Students. The analyses were based on descriptive statistics, confidence intervals for the mean, Spearman correlations, Cronbach’s alpha, and exploratory factor analysis. Results: The reliability of the evaluative rubric was excellent with Cronbach’s alpha greater than 0.70. The internal consistency showed 100% success, as each evaluation criterion presented a correlation higher than 0.40 with its dimension. The discriminant power and the validity of the items evaluated were also excellent according to the factorial analysis. In the Programming dimension, an average of 4.17 was found (95% CI = 4.68-4.76), in Administration 4.56 (IC95 % = 4.50-4.62) and in the Student dimension 4.74 (95% CI = 4.70-4.78), without registering statistically significant differences between the cohorts. Conclusion: There is a rubric for the external evaluation of professional practices with excellent reproducibility and psychometric validity. The process of professional practices presented an excellent performance during its first decade of operation, according to the perspective of the participating external institutions, which demonstrates the excellent performance of the IEM program in the evaluated criteria.

The ornithological world has 4 global checklists (as of early 2020). While 3 follow the results of peer-reviewed research at varying pace and conservatism, the HBW/BirdLife checklist, which is adopted by the global Red List authority, has implemented Tobias et al.'s (2010) 7-point scoring system to overhaul global ornithological treatment. Critically received in some academic quarters, this scoring system is lauded by other ornithologists for its simplicity and reproducibility, a claim that remains to be tested. We subjected 26 ornithologists to a set of 48 bird skins belonging to 20 controversial taxonomic complexes and observed a wide variance in scoring results, in most cases straddling anywhere from far below to above the species threshold of the 7-point rule and casting doubt on claims of high reproducibility. For a detailed assessment of genuine taxonomic discord, we compared the taxonomic coverage of the avifauna of the Indonesian Archipelago (comprising ~1,400 species) between the HBW/BirdLife checklist, other major authorities, and the peerreviewed literature. We detected that controversial treatments supported by the 7-point rule but at odds with the peerreviewed literature predominantly refer to lumps, not splits, which are the usual subject of modern taxonomic quarrels. Notably, the method tends to unite morphologically (and sometimes vocally) cryptic forms into single larger species because of its inability to accommodate molecular and massive bioacoustic datasets that would indicate otherwise. On the other hand, the 7-point rule has produced numerous novel proposals for splits that may or may not be corroborated by future peer-reviewed inquiry. We recommend the 7-point rule as one of the multiple unofficial exploratory tools to flag cases of potentially cryptic species requiring further inquiry, but we advise against its adoption by other taxonomic authorities and the ornithological community.

La pandemia de COVID-19 ha catalizado una serie de prácticas académicas y cuando la superemos, la geografía y, sobre todo la dinámica de los grupos de investigación será otra. Quizá seremos más eficaces, pero el rasgo que será más indeleble de ese cambio lo constituirá la incorporación cotidiana de prácticas de ciencia abierta, repetible y reproducible. El cambio cualitativo de la investigación a la “e-investigación”, describe nuevas formas de producción y diseminación del conocimiento e impone nuevas metodologías para manejar, administrar, analizar y preservar este “diluvio de datos”. La repetibilidad y la reproducibilidad de los resultados científicos en la ciencia centrada en datos ha sido detectado como un un problema creciente. Las publicaciones académicas están llamadas a transformarse, exigiendo acceso a los datos y aplicaciones computacionales que soportan los resultados. En esta nota editorial comentamos y reflexionamos sobre algunas de las metodologías y herramientas que se disponen para promover la repetibilidad/reproducibilidad de los experimentos. Discutimos el enfoque metodológico que emerge del Instituto Turing del Reino Unido. Presentamos una evaluación de las herramientas para construir repositorios de datos que existen actualmente.

Introduction: Introduction: assessing the relationship between childhood diseases and nutrient intake is a crucial issue that requires valid and reliable dietary assessment tools in this period of physical and physiological development. Objective: the present study aimed to develop and validate a food frequency questionnaire (FFQ) to assess nutrient intake in Jordanian children. Methods: in this validation study, nutrient intake as obtained from a culturally sensitive quantitative FFQ was compared to nutrient intake as assessed by four 24-hour dietary recalls (24-HRs) between September 2017 and May 2018. One hundred and thirty-six children aged 6-18 years were enrolled from selected schools in Amman, Jordan. Children or their caregivers were asked to complete the FFQ during an initial face-to-face interview. Four 24-HRs were collected weekly over one month. Of these children, 50 also took part in the reproducibility phase, which involved a repeat completion of the FFQ within 1 month. Results: the intraclass correlation coefficients between the two FFQs ranged from 0.5 for trans-fats to 0.96 for calcium. Correlation coefficients between dietary intake estimates derived from the FFQ and 24-HRs were significant at p < 0.05. The highest correlation was detected for energy (0.8) while the lowest was identified for trans-fatty acids (0.04). For all nutrients, over 60 % of participants were classified into the same or adjacent quartile of crude and adjusted intake. Bland-Altman plots showed a satisfactory agreement between the two methods for energy and proteins. Conclusion: the FFQ showed a good reproducibility and a reasonable relative validity for most nutrients. [ABSTRACT FROM AUTHOR]- Published

COVID-19 pandemic , *APPLICATION software , *COMPUTER programming , *RESEARCH teams , *SOCIAL groups - Abstract
The COVID-19 pandemic has catalyzed several academic practices, and when it ends, the geography and especially the dynamics of research groups will be completely different. We will have other practices, and, in many cases, we will be more effective. Perhaps the most indelible feature of that change will be the day-to-day incorporation of open, repeatable, and replicable science practices. The qualitative change from research to 'e-research' describes a new way to produce and disseminate knowledge. It also imposes new methodologies to manage, administer, analyze and preserve this 'data deluge'. The repeatability and reproducibility of scientific results in data-centred science become a growing and significant issue. Undoubtedly, academic publications should be transformed, demanding open access to data and direct availability to computer codes and applications that support the results. In this editorial, we comment and reflect on some of the methodologies and tools available to promote the repeatability/reproducibility of experiments. [ABSTRACT FROM AUTHOR]

Introduction: Introduction: currently, it is important to determine whether food frequency questionnaires (FFQ) are valid tools to collect information on usual diet in children. Objective: we evaluated the reproducibility and validity of the semi-quantitative FFQ used in a Spanish cohort of children aged 4-7 years. Methods: to explore its reproducibility, parents filled a 138-item FFQ at baseline (FFQ-0) and then one year later (FFQ-1). To explore its validity, the FFQ-1 was compared with four weighed 3-day dietary records (DRs) that were used as standard of reference. To estimate associations we calculated deattenuated Pearson's correlation coefficients to correct for season-to-season variability, and the Bland-Altman index. We also calculated the weighted kappa index and assessed participant's gross misclassification across quintiles. We analyzed data from 67 (for reproducibility) and 37 (for validity) children aged 4-7 years old, recruited by the pilot study of the SENDO project. Results: regarding reproducibility, we found mean Bland-Altman indexes of 0-10.45 % for nutrients and 1.49 %-10.45 % for foods. The adjusted r ranged between 0.29 and 0.71, and between 0.27 and 0.74 for nutrients and foods, respectively. Regarding validity, we found mean Bland-Altman indexes of 0 %-16.22 % and 0 %-10.81 % for nutrients and for food groups, respectively. The deattenuated r ranged between 0.38 and 0.81 for nutrients, and between 0.53 and 0.68 for foods. The weighted kappa index for agreement across quintiles ranged from 54.1 to 85.1 for nutrients, and from 55.4 to 78.4 for food groups. Conclusions: our results showed acceptable levels of both reproducibility and validity, and that the ad-hoc developed FFQ is a valid tool for assessing usual diet in Spanish preschoolers.

The value of new archaeological knowledge is strongly determined by how credible it is, and a key measure of scientific credibility is how replicable new results are. However, few archaeologists learn the skills necessary to conduct replication as part of their training. This means there is a gap between the ideals of archaeological science and the skills we teach future researchers. Here we argue for replications as a core type of class assignment in archaeology courses to close this gap and establish a culture of replication and reproducibility. We review replication assignments in other fields and describe how to implement a replication assignment suitable for many types of archaeology programs. We describe our experience with replication in an upper-level undergraduate class on stone artifact analysis. Replication assignments can help archaeology programs give students the skills that enable transparent and reproducible research. [ABSTRACT FROM AUTHOR]
