Six steps towards operationalising freshwater ecoacoustic monitoring
Authors: Linke Simon , Gifford Toby , Desjonquères Camille 
Published: December 2019

Abstract

Applications in bioacoustics and its sister discipline ecoacoustics have increased exponentially over the last decade. However, despite knowledge about aquatic bioacoustics dating back to the times of Aristotle and a vast amount of background literature to draw upon, freshwater applications of ecoacoustics have been lagging to date.

In this special issue, we present nine studies that deal with underwater acoustics, plus three acoustic studies on water‐dependent birds and frogs. Topics include automatic detection of freshwater organisms by their calls, quantifying habitat change by analysing entire soundscapes, and detecting change in behaviour when organisms are exposed to noise.

We identify six major challenges and review progress through this special issue. Challenges include characterisation of sounds, accessibility of archived sounds as well as improving automated analysis methods. Study design considerations include characterisation analysis challenges of spatial and temporal variation. The final key challenge is the so far largely understudied link between ecological condition and underwater sound.

We hope that this special issue will raise awareness about underwater soundscapes as a survey tool. With a diverse array of field and analysis tools, this issue can act as a manual for future monitoring applications that will hopefully foster further advances in the field.

Abstract

Passive acoustic monitoring is gaining momentum as a viable alternative method to surveying freshwater ecosystems. As part of an emerging field, the spatio‐temporal replication levels of these sampling methods need to be standardised. However, in shallow waters, acoustic spatio‐temporal patchiness remains virtually unexplored.

In this paper, we specifically investigate the spatial heterogeneity in underwater sounds observed within and between waterholes of an ephemeral river at different times of the day and how it could affect sampling in passive acoustic monitoring.

We recorded in the Einasleigh River, Queensland in August 2016, using a linear transect of hydrophones mounted on frames. We recorded four times a day: at dawn, midday, dusk, and midnight. To measure different temporal and spectral attributes of the recorded sound, we investigated the mean frequency spectrum and computed acoustic indices.

Both mean frequency spectrum and index analyses revealed that the site and diel activity patterns significantly influenced the sounds recorded, even for adjacent sites with similar characteristics along a single river. We found that most of the variation was due to temporal patterns, followed by between‐site differences, while within‐site differences had limited influence.

This study demonstrates high spatio‐temporal acoustic variability in freshwater environments, linked to different species or species groups. Decisions about sampling design are vital to obtain adequate representation. This study thus emphasises the need to tailor spatio‐temporal settings of a sampling design to the aim of the study, the species and the habitat.

AbstractRobust estimates of CO2 budget, CO2 exchanged between the atmosphere and terrestrial biosphere, are necessary to better understand the role of the terrestrial biosphere in mitigating anthropogenic CO2 emissions. Over the past decade, this field of research has advanced through understanding of the differences and similarities of two fundamentally different approaches: “top‐down” atmospheric inversions and “bottom‐up” biosphere models. Since the first studies were undertaken, these approaches have shown an increasing level of agreement, but disagreements in some regions still persist, in part because they do not estimate the same quantity of atmosphere–biosphere CO2 exchange. Here, we conducted a thorough comparison of CO2 budgets at multiple scales and from multiple methods to assess the current state of the science in estimating CO2 budgets. Our set of atmospheric inversions and biosphere models, which were adjusted for a consistent flux definition, showed a high level of agreement for global and hemispheric CO2 budgets in the 2000s. Regionally, improved agreement in CO2 budgets was notable for North America and Southeast Asia. However, large gaps between the two methods remained in East Asia and South America. In other regions, Europe, boreal Asia, Africa, South Asia, and Oceania, it was difficult to determine whether those regions act as a net sink or source because of the large spread in estimates from atmospheric inversions. These results highlight two research directions to improve the robustness of CO2 budgets: (a) to increase representation of processes in biosphere models that could contribute to fill the budget gaps, such as forest regrowth and forest degradation; and (b) to reduce sink–source compensation between regions (dipoles) in atmospheric inversion so that their estimates become more comparable. Advancements on both research areas will increase the level of agreement between the top‐down and bottom‐up approaches and yield more robust knowledge of regional CO2 budgets.

AimPain can have a critical negative impact on the quality of life of institutionalized older people. This study aimed to examine the characteristics of pain and associated factors among older people at nursing homes in Korea.MethodsA nationwide survey was carried out on the functional status of 1444 older residents at 91 nursing homes using the interRAI Long‐Term Care Facilities instrument. The frequency, intensity, severity and consistency of pain were assessed, and data on potential attributes at the resident and facility levels were collected. Multivariate and multilevel regression analysis models were developed.ResultsMore than one‐third (36.7%) of older residents had pain. Pain prevalence differed by several sociodemographic and clinical factors, including sex, depressive symptoms, cognition, or whether or not the resident was a Medical Aid beneficiary. Pain prevalence also varied according to nursing home size and location. In the multivariate, multilevel regression analyses, both having severe pain and having consistent pain were positively associated with depressive symptoms, and the pain experience was significantly lower among older residents in nursing homes that met the nursing staffing standard.ConclusionsThis is the most comprehensive study on pain assessment in long‐term care facilities in Korea using a representative sample so far. Pain is prevalent among nursing home residents in Korea. Besides individual factors, facility characteristics – in particular, meeting the staffing standard – were important to pain control, which implies there is room for improving pain assessment and management through advancing quality of care policies.

AimAn easily performed method for examination of muscle abnormalities is anticipated. We aimed to elucidate the clinical usefulness of simple assessments for muscle abnormality including a simple five‐item questionnaire (SARC‐F) in chronic liver disease patients.MethodsFrom February to July 2019, 383 outpatients (median age 71 years, 259 men; chronic hepatitis (CH) : liver cirrhosis Child–Pugh A : liver cirrhosis Child–Pugh B : liver cirrhosis Child–Pugh C = 157:176:39:11) who underwent a computed tomography examination were enrolled. SARC‐F, previously reported cut‐off values for muscle strength decline (MSD; handgrip), pre‐muscle volume loss (pre‐MVL), calf circumference and finger‐circle test results were used, and these results were analyzed retrospectively.ResultsA high SARC‐F score (≥4) was observed in 25 patients, and a low score (<4) in 358 patients. The frequency of high SARC‐F increased significantly with progression of chronic liver disease (chronic hepatitis : liver cirrhosis Child–Pugh A : liver cirrhosis Child–Pugh B/C = 2.5%:8.0%:14.0%, P=0.010). MSD frequency was 22.4% in men and 41.1% in women. Muscle volume loss and pre‐MVL were noted in 22% and 30.5%, respectively, of the male patients, and 9.7% and 32.3%, respectively, of the female patients. In cases with high SARC‐F and MSD, calf circumference and finger‐circle abnormalities were found in 56% and 40.0% of patients, respectively, whereas those values for patients with low SARC‐F and MSD were 14.5% and 10.6%, respectively (P < 0.001, for each; positive/negative predictive values: 0.560/0.855 and 0.400/0.894, respectively). Each SARC‐F item showed a good area under the curve for MSD, but not pre‐MVL.ConclusionSARC‐F score in combination with MSD and calf circumference or finger‐circle test results may be an easy and simple method for surveillance of chronic liver disease patients with a high risk of sarcopenia and decline of quality of life.

AbstractObjectiveThis systematic review aimed to evaluate the association of traumatic dental injury (TDI) on oral health‐related to quality of life (OHRQoL) in children and adolescents.MethodsA focused structured question using Population (P), Exposition (E), Comparisons (C), Outcomes (O) (PECO) was designed: “Does traumatic dental injury impact OHRQoL of children and adolescents?” A broad search according to Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) was conducted. Evaluation criteria of methodological quality and risk of bias control were applied to selected articles. A fixed‐effect model was used for the meta‐analysis, and the quality of the evidence was performed using Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.ResultsNineteen studies were qualified with moderate to high quality, and 11 studies were considered for meta‐analysis. Negative impact on OHRQoL was detected for children in the symptoms domain (P = .005; IC; −0.07 [−0.12, −0.02]) with moderate certainty of evidence quality level (GRADE). For adolescents, the total scale and all domain presented statistical significance (P < .05) with moderate certainty of evidence in the areas of functional limitation and social well‐being (GRADE).ConclusionsBased on articles with moderate to high quality, the impact of TDI on OHRQoL in children under age 10 was only significant in the symptom domain using Early Childhood Oral Health Impact Scale (ECOHIS). The impact of TDI on OHRQoL in early adolescents aged 11 to 14 was significant in every assessed domain using Child Perception Questionnaire (CPQ11‐14). However, future studies should be done improving the available certainty of evidence considered moderate. (CRD42016035686).

Published: December 2019

AbstractIntroductionThe delta check quality control measure has been applied in haematology testing for a long time. Although the delta check graph of haematology test had been reported by Berend Houwen in 1989, problems still exist in its clinical application. This study aims to provide a simplified and practical process for the improvement of validity in haematology testing.MethodsWe analysed a total of 5260 patients with two sequential complete blood counting results, taken in 1 week, to verify the delta check curve. The delta check equations were simulated using the sigma plot 13.0 software. Validations of test results were performed on patients from the haematology, oncology and other departments.ResultsThree equations of the delta check limits for mean corpuscular volume (MCV), haemoglobin, white blood cell and platelets were simulated. The following two limitation lines were selected: limit A (ΔA) and limit B (ΔB), wherein ΔA was to simplify the review rules and ΔB to check random errors. Delta check procedures including rules and equations were established for clinical use, and the re‐inspection rate was reduced in different departments using the delta check model in clinical validation.ConclusionThe simplified delta check limitation formulae are meaningful for data review and may help the laboratory technician optimize workflow and reduce workload.

AbstractIntroductionPatients with acute promyelocytic leukemia (APL) are characterized by the highest expression of Wilms' tumor 1 (WT1) gene compared with other subtypes of acute myeloid leukemia, and yet this molecular marker is almost never used for risk stratification and in therapy response monitoring.MethodsQuantitative assessment of Wilms' tumor 1 (WT1) gene transcripts was performed using real‐time PCR method. The bone marrow samples were collected at the time of diagnosis for 47 APL patients, and for 31/47 patients during follow‐up/relapse of the disease (129 samples in total). We examined how this molecular marker can be used for prognosis and minimal residual disease (MRD) monitoring.ResultsIncreased WT1 expression was found in 34% of patients. WT1high status was an independent unfavorable factor for early death occurrence and was associated with shorter overall survival (OS). Assessment of log reduction value of WT1 expression in paired diagnosis/complete remission samples did not reveal its impact on relapse rate, disease‐free survival, and OS. Also, measurement of WT1 expression level at different time points during therapy was not a reliable method for MRD monitoring.ConclusionIncreased expression of WT1 gene detected in high proportion of APL patients could be considered as a marker for more precise risk stratification models in an attempt to further improve treatment and outcome of APL patients.

AbstractThe 0.65Bi(Mg1/2Ti1/2)O3‐0.35PbTiO3 (0.65BMT‐0.35PT) ceramic, nearby morphotropic phase boundary (MPB), between tetragonal and rhombohedral was prepared. Dielectric permittivity dependence of temperature exhibits a re‐entrance dipole glass‐like behavior near room temperature. The behavior was described by the Vogel‐Fulcher law and the new glass model. Furthermore, a phenomenological statistical model was employed to determine the distribution of clusters dependence of temperature. The lattice dynamics of the 0.65BMT‐0.35PT ceramic was estimated by Raman spectroscopy from 298‐723 K. A disruption of ferroelectric long‐range order and an occurrence of local lattice distortion were revealed. The relaxor‐ferroelectric (r‐FE) nature of the 0.65BMT‐0.35PT was characterized by polarization‐electric field P(E). A close relation between the distribution of clusters and ferroelectric properties was established.

AbstractLower flight reaction is closely related to higher production in cattle, but the genetic basis of lower flight reaction is not clearly understood. Here, we sampled a total of 45 Brahman cattles and 166 Yunling cattles with flight distance (FD), and 73 Brahman cattles and 288 Yunling cattles with crush score (CS) and flight speed (FS), whereas there were 45 Brahman cattles and 161 Yunling cattles with all three traits. The FD, CS and FS in Brahman cattle were significantly lower than those in Yunling cattle. The flight reaction traits had negative correlation with conformational traits (e.g., body weight, withers height and body length). Based on SNPs derived from a subset of 162 whole genomes (25 Brahman genomes and 100 Yunling genomes with FD, 30 Brahman and 131 Yunling genomes with CS and FS), genome‐wide association study with mixed linear model was performed to test potential associations between flight reaction traits and genomic variants. We identified five, two and two genomic loci suggestively associated with FD, CS and FS, respectively. Five out of five candidate genes for FD (LOC789753, LRP6, CTIF, SLC9A9 and ZEB1) were reported to be related to Alzheimer's disease representing cognitive impairment in human, which was consistent with the finding that cognitive‐behavioural intervention decreased the FD of cows to human. In CS, a very strong association locus was assigned to CDH8, a cadherin involved in synaptic adhesion, axon outgrowth and guidance, whose deletion was associated with autism spectrum disorder. In FS, a very strong association locus was assigned to GABRG2, a gamma‐aminobutyric acid (a major inhibitory neurotransmitter in brain) receptor, whose polymorphisms were associated with suicidal behaviour in schizophrenia patients. Our findings will provide targets for molecular‐marker selection and genetic manipulation of cattle improvement to meeting the growing demand for lower flight reaction to human.
Predicting students' knowledge after playing a serious game based on learning analytics data: A case study

AbstractSerious games have proven to be a powerful tool in education to engage, motivate, and help students learn. However, the change in student knowledge after playing games is usually measured with traditional (paper) prequestionnaires–postquestionnaires. We propose a combination of game learning analytics and data mining techniques to predict knowledge change based on in‐game student interactions. We have tested this approach in a case study for which we have conducted preexperiments–postexperiments with 227 students playing a previously validated serious game on first aid techniques. We collected student interaction data while students played, using a game learning analytics infrastructure and the standard data format Experience API for Serious Games. After data collection, we developed and tested prediction models to determine whether knowledge, given as posttest results, can be accurately predicted. Additionally, we compared models both with and without pretest information to determine the importance of previous knowledge when predicting postgame knowledge. The high accuracy of the obtained prediction models suggests that serious games can be used not only to teach but also to measure knowledge acquisition after playing. This will simplify serious games application for educational settings and especially in the classroom easing teachers' evaluation tasks.

Published: December 2019

AbstractThe purpose of this research was to compare the effectiveness of physical and virtual tangrams on preschool children's learning engagement and achievement. Children listened to an e‐storybook narration and solved puzzles individually. The experimental group (N = 31) completed puzzles embedded in the e‐storybook using virtual tangrams, while the control group (N = 30) completed the same puzzles using physical tangrams on outlines drawn on a paper. Results indicated that the experimental group had significantly higher overall engagement than the control group. The experimental group had significantly higher learning achievement (time taken to complete outlines) when using virtual tangrams. It is hoped that the study will be beneficial to classrooms concerning how to use tangrams in teaching and learning and to instructional designers on how to design an e‐storybook for young readers.
