Published: October 2021

Understanding the role diet plays in the structure of food webs is
vital, and dietary knowledge is key for conservation management success.
There is limited knowledge of the diets of woodland bird species, due
largely to difficulties in accurately identifying plant and invertebrate
taxa being consumed. Here, we show the effectiveness of multi-marker
faecal metabarcoding to provide the most in-depth dietary analysis of a
generalist passerine, the Hawfinch (Coccothraustes coccothraustes,
Linnaeus), to date. Faecal samples were obtained from 2016-2019 from
Hawfinch populations prior to and during the breeding season throughout
the UK. DNA was extracted from 263 samples and amplified using Internal
Transcribed Spacer 2 (ITS2) and cytochrome C oxidase subunit I (COI)
barcodes. Using high-throughput sequencing (HTS), we identified 49 and
97 ITS2 and COI zero radius operational taxonomic units (zOTUs)
respectively which equated to reputed dietary items. The herbivorous
element of Hawfinch diet was dominated by naturally occurring taxa such
as beech (Fagus sylvatica, Linnaeus), hornbeam (Carpinus betulus,
Linnaeus) and oak (Quercus sp., Linnaeus). The most taxon rich and
commonly recorded invertebrate taxon identified was Lepidoptera. We
found Hawfinch diet varied spatially, as well as between sexes. Hawfinch
showed broad dietary plasticity and utilised multiple resources within
their foraging environments. Our study shows the potential of
multi-marker DNA metabarcoding to reveal subtle dietary differences, but
also highlights the challenges of studying omnivorous species using
metabarcoding methods.
Credit Redistribution by Listed Manufacturing Firms in Pakistan and the Moderating Role of Financial Depth
Authors: Ahmad Nisar , Nafees Bilal , Rasheed Abdul
Published: October 2021

An enhancement in the financial depth (FD) increases the availability of formal credit to firms. Resultantly credit redistribution (CR) by firms is likely to be reduced as they require less trade credit (TC). To provide evidence, how do managers respond to changes in financial depth while making adjustments in their trade credit policy, this paper aims to study the impact of financial depth on credit redistribution by listed manufacturing firms (LMFs). For the firm-level variables, we used a data set of 327 firms listed on PSX for the period 2005 to 2018. Private credit to GDP ratio and market capitalization to GDP ratio are used as proxies for financial depth. Unlike earlier studies, we applied a two-step System GMM estimator to control the endogeneity. The results of the regression analysis display a positive relationship between the use and the supply of trade credit by LMFs. It reveals that LMFs redistribute credit to their customers through trade credit channel. We found a significant and negative impact of FD on the supply of TC by LMFs. Further, we established that financial depth as a moderator has a buffering impact on the credit redistribution by listed firms. The study highlights the moderating role of FD and suggests the financial policymakers of firms to modify their credit policies in response to changes in financial depth. For future research, we suggest the investigation of the effect of financial policy interventions on credit redistribution by small and non-listed firms.

Authors: Danish Habib Muhammad , Jalil Shah Hassan , Qayyum Abdul
Published: October 2021

Energy conservation is an economic, social, and environmental issue that offers various academic, practical, and policy implications. The growing magnitude, complexity, and relevance of energy wastage have attracted the attention of scholars and practitioners. There is a lack of consumer awareness towards electricity conservation practices of household consumers in the context of developing countries. This research utilized the theory of planned behavior to explain sustainable behavioral intentions in the context of electricity conservation. This research aims to measure the effect of beliefs, values, and attitudes on sustainable behavioral intentions in the energy conservation context. This research hypothesized awareness, compatibility, perceived value, resistance to change, and actual gain as predictors of attitude towards energy conservation and sustainable behavioral intentions. Using survey methodology, purposive sampling techniques were used to collect the data from young household consumers. Data of 246 electricity consumers of Pakistan were analyzed using confirmatory factor analysis (CFA) and structural equation modeling (SEM). Results of the study validate a significant relationship between attitude towards energy conservation and sustainable behavioral intentions. Based on results, it has been established that the amount of actual gain intentions and awareness are the main contributors to attitude towards energy conservation and sustainable behavioral intention. Compatibility and resistance to change were also significant precipitators of attitude towards energy conservation and sustainable behavioral intention. Perceived value was found a significant predictor of attitude towards energy conservation while insignificant towards sustainable behavioral intention. The study findings have a significant impact on government, policymakers, marketers, and academics interested in developing strategies to mitigate the effects of energy wastage. Prevention of resource wastage depends upon the awareness and consumption practices of the customers.

Authors: Johansen Heidi , Velvin Gry , Fugl-Meyer Kerstin , Lidal Ingeborg Beate
Published: October 2021

Objective: To explore life satisfaction among adults with Loeys-Dietz and those with vascular Ehlers-Danlos syndrome.
Design: Postal survey in 2018.
Participants and methods: Persons with molecularly verified Loeys-Dietz syndrome or vascular Ehlers-Danlos syndrome were recruited through the TRS [AQ2] National Resource Centre for Rare Disorders in Norway. The study used the Life Satisfaction Questionnaire 11, Hospital Anxiety and Depression Scale, Fatigue Severity Scale, and questions about physical activity and disease burden. Descriptive statistics were conducted with Bonferroni corrections.
Results: The response rate was 74%, 52 participants, age range 18–68 years, and 58% were women. Only half of the participants were satisfied with their lives as a whole. Participants reported dissatisfaction with vocation, somatic health, and sexual life in particular. Participants with vascular Ehlers-Danlos syndrome (n = 18) were satisfied with more areas of life than those with Loeys-Dietz syndrome (n = 34). Low overall satisfaction was significantly associated with severe fatigue (p = 0.002) and symptoms of anxiety (p = 0.001).
Conclusion: This study provides important information about living with Loeys-Dietz syndrome and vascular Ehlers-Danlos syndrome. Future studies should identify factors that reduce/increase life satisfaction. Professionals in welfare systems need more information about the unique challenges of living with these diagnoses. Guidelines for research and clinical measurements of life satisfaction should be updated.
A Novel Nondestructive Procedure for Tire Tread Viscoelastic Characterization
Authors: Genovese Andrea , Pastore Sebastian Rosario
Published: October 2021

Vehicle dynamics is largely influenced by the phenomena occurring in the tire-road interface, and a great portion of these phenomena is mainly conditioned by the viscoelastic properties of the tire tread compound. It is not surprising that the possibility of obtaining the viscoelastic response of a compound by means of a nondestructive procedure is a growing research topic that affects application fields ranging from monitoring of the material performance during its entire life cycle to the quantitative analysis of product quality and repeatability of production processes. In this article, a novel nondestructive procedure for the viscoelastic characterization of tire tread compound is proposed. A portable instrument, based on instrumented indentation, was designed and prototyped with the aim to allow a real-time assessment of moduli directly on site. The testing procedure adopted to perform the test on three different compounds was described. A signal-processing procedure was developed for the identification of compound stiffness and damping parameters from which viscoelastic moduli were estimated. The results were also compared with the Dynamic Mechanical Analysis characterization showing the same relative ranking between the compounds with a different trend in temperature due to the amount of the tests' indentation depth.
Theoretical Tire Model Considering Two-Dimensional Contact Patch for Force and Moment
Authors: Nakajima Yukio , Hidano Shunya
Published: October 2021

The new theoretical tire model for force and moment has been developed by considering a two-dimensional contact patch of a tire with rib pattern. The force and moment are compared with the calculation by finite element method (FEM). The side force predicted by the theoretical tire model is somewhat undervalued as compared with the FEM calculation, while the self-aligning torque predicted by the theoretical tire model agrees well with the FEM calculation. The shear force distribution in a two-dimensional contact patch under slip angle predicted by the proposed model qualitatively agrees with the FEM calculation. Furthermore, the distribution of the adhesion region and sliding region in a two-dimensional contact patch predicted by the theoretical tire model qualitatively agrees with the FEM calculation.

Authors: Israfilova Alina , Garcia Mario A. , Kaliske Michael
Published: October 2021

Isogeometric analysis (IGA) has become an alternative to standard finite element analysis (FEA) in many areas of engineering. Its powerful tools for model generation and flexibility of basis functions make this relatively new approach attractive for tire analysis and its computational challenges.

This contribution summarizes the benefits of IGA for complex tire simulations starting from model generation and the subsequent transition to the environment of numerical analysis without losing accuracy at the parametrizing stage. It presents results of further development work on earlier pioneering examples of the application of IGA in pneumatic tire analysis. In addition to the analysis of vertical stiffness, for the first time, velocity and acceleration fields are addressed and compared with experimental results and standard FEA simulations, with a focus on benefits of the continuity of basis functions within the contact patch. The numerical issues that arise in IGA at the enforcement of contact and the application of inelastic materials with inclusions of reinforcing layers are studied. Moreover, the important advantages of the possibility to use higher order functions for simulations of tire maneuvers are addressed within the steady-state framework. Numerical examples are provided to illustrate the capabilities of IGA. Concluding remarks on the results close the publication.
Wheel Speed Effect on Transient Lateral Force and Its Characterization by Ramp-Step Steer Test Method
Authors: Li Yi
Published: October 2021

The concept “relaxation length” serves as one of several ways to characterize the transient lateral response for a rolling tire. Most test methods developed to identify relaxation length tightly link to Pacejka’s single-contact-point linear transient model. Its underlying assumption is that the traveled distance during the transition interval is always a constant regardless of the wheels’ linear rolling speed. The current research provides physical data against this strong assumption. The data is acquired through a newly-developed test method named the “ramp-step steer method”.

The ramp-step steer method features a nonstop, high rolling speed, and fast-changing slip angle procedure that cannot be fulfilled by the conventional “start-stop-resume” step steer method. Thanks to the high dynamic capability of the equipment in GCAPS Corp., the proposed test method becomes feasible. A novel data postprocessing scheme accompanies the test method as well. The ramp-step steer method is independent of any specific models and replicates the scenario of a rolling tire subjected to a sudden slip angle change from on-vehicle to an indoor environment. The wheel speed effect on the tires’ transient lateral response is reflected through a proposed quantity, Ly, which is a more general descriptor and can downscale to relaxation length under specific circumstances. Ly itself does not associate with any model, so the remaining study explains the speed effect through an updated model. The present research aims to provide a better way of characterizing tires’ lateral transient behavior and is not an alternative to identify the key parameter “relaxation length” in Pacejka’s model. Another contribution of the research is categorizing and separating the hierarchy of various transient tire models.
A Universal Approach to Tire Forces Estimation by Accelerometer-Based Intelligent Tire: Analytical Model and Experimental Validation

Published: October 2021

Efforts to improve the performance and safety of vehicles include placing active sensing components (e.g., embedded microsensors) within tires result in intelligent tires. One application of intelligent tire is tire force estimation based on accelerometers. However, its development is limited due to the difficulty of relating the tire force to kinematical information by model-based theory. In this manuscript, a universal approach to tire forces estimation by the accelerometer-based intelligent tire is formulated and experimentally validated. First, a microelectromechanical system accelerometer-based intelligent tire prototype is established with the function of on-board monitoring of tire forces. Then, a theoretical rolling kinematics model is proposed for illustrating the mechanisms of acceleration fields, resulting from the coupling effect of rigid body motion and elastic deformation. An analytical model is formulated to estimate the vertical force in real time. Furthermore, the beam model is adopted to describe lateral deformations of the tire belt, directly linking lateral acceleration and lateral force. Finally, the lateral force can be estimated by lateral acceleration and vertical force already estimated. Based on a universal analytical model, the lateral force estimation method realizes high accuracy under different circumstances, even with unified coefficients, by clarifying and eliminating the influence of ply steer. A field test and two bench experiments have been conducted to fully validate the developed model. It can be concluded that the theoretical-analysis-based estimation model realizes an encouraging tire force estimation application with an intelligent tire hardware system.

Complex conditions at work places cause exhaustion of psychological and physiological resources of a human, which affects employee’s efficiency. The occupational burnout syndrome, by a number of signs, is similar to the emotional burnout, however, its source is a situation at work. The phenomenon includes a set of negative emotions and experiences directly associated with work. The basic signs of occupational burnout are as follows: the feeling of eternally deep fatigue, overwhelming exhaustion, cynical and indifferent attitude to colleagues, disappointment in one’s own work results, and depreciation of one’s own expertise. One might think that he/she works insufficiently, then gradually the disappointment grows and causes anxiety and complete exhaustion. When unattended, these emotional disorders develop into severe diseases. The occupational burnout is a phenomenon that recently became of focus of research of various disciplines, from psychology to labor protection. With the other occupational deceases caused by hazardous factors of production environment, the occupational burnout as a result of the effects of stress on human organism leads to decreasing work efficiency, is harmful for employee’s health and may cause illnesses. Employee’s adaptation to occupational requirements is associated with development of useful personal characteristic and suppression of those hampering one’s professional functioning. Such changes affect the psychological and emotional condition of an employee. In order to determine the recommendations how to overcome stress at work, the level of occupational burnout of 14 employees of a design & construction bureau was conducted via using V.V. Boiko’s test «The diagnostics of emotional burnout level» modified by E.P. Ilyin.

The analytical review of labor conditions in the oil mines of the Yaregskoye field has demonstrated that the majority of work places (82 %) are considered hazardous, of subclass 3.1–3.3. The analysis of the basic process operations for high-viscosity oil production using the thermoshaft method has determined the combinations of hazardous production factors at work places. Studying the diversity of versions and combinations of negative factors and their complex impact on oil mine workers enabled detecting a synergetic effect that increases the risk of development of occupational diseases. It is established that for occupational risks assessment considering the potential interaction of hazardous production factors and their impact on personnel’s health is crucial. Today, the synergetic effects are not considered for occupational risk assessment in oil mines. Development of a methodological approach to occupational risk assessment including synergy is required. The suggested method is based on building up a mathematical model for occupational risk assessment with combined effects of negative factors that uses the combined effect coefficient considering the impact of synergetic effect. Comparing the data on labor conditions’ classes, occupational disease indices and obtained results, including the synergetic effects for the main underground occupations of the oil mines has demonstrated the bias approach for the earlier occupational assessment that neglected occupational risks to health in conditions of combined impact of negative factors. Within calculations, the significance of synergism math model for occupational risk assessment is confirmed.

Published: October 2021

Daylighting is interpreted as natural sunlight allowed into an indoor space. Passive lighting strategies are considered fundamental in achieving a high performing sustainable building, which affects the visual and thermal comfort, and energy performance of a building. Many strategies in controlling daylighting are known, however, the wrong implementation can lead to a negative effect. The results obtained need to reach a balance between daylighting and thermal performance. This review is conducted to analyse the concept and factors that affect the balance through different research parameters. The performance factors include energy, comfort and perception or view. The different methods of achieving the balance are categorized into three, which are parameter relation, combination, and multi-objective optimization. Building shading devices are considered as one of the major solutions to reach thermal-daylighting balance. Through a comprehensive review, adjustable shading control is recommended as a better option for building shading device for buildings to achieve the optimum balance.

Published: October 2021

Este artigo constitui-se em um estudo sobre o hotel em uma perspectiva teórica, histórica e crítica, bus­cando ampliar o conhecimento sobre as mutações das tipologias arquitetônicas na modernidade no contexto de um desígnio mais amplo e promover a discussão conceitual e transdisciplinar entre a arquitetura e o turismo. O objetivo do trabalho é compreender as articulações entre a gênese e meta­morfoses do hotel na modernidade e as práticas sociais relacionadas à hospitalidade, à viagem e, mais recentemente, às atividades de lazer e turismo. O trabalho busca ainda discutir continuidades e des­continuidades no processo de transformação dessa categoria de edifícios, levantando como argumento a ideia de que os hotéis são, por excelência, tipolo­gias arquitetônicas híbridas. Por fim, duas categorias de hotéis importantes surgidas na modernidade são analisadas: o “Grande Hotel” e o “Hotel de Turismo” que, por terem caráter híbrido, possuem significa­tivo potencial de conservação na contemporaneidade, por intermédio de intervenções e estratégias de reuso para outros fins programáticos.

Corruption is an extraordinary crime (extraordinary crime), so the handling must be done with extraordinary efforts. In this reform era, corruption is increasingly rampant involving various actors, from the central government to the lowest. From Transparency International (TI) data, Indonesia's 2017 Corruption Perception Index (CPI) is 37 and is ranked 96 out of 180 countries surveyed globally. Responding to the increasingly prevalent phenomenon of corruption, the world of education has begun to improve to answer the challenges of the swift currents of corruption. One of the efforts made is curriculum change. Curriculum changes that have been intensively discussed lately are the inclusion of anti-corruption character education at the pre-school to tertiary education levels. The purpose of this activity is to provide OSIS administrators with an understanding of anti-corruption character education, including understanding, rules, and implementation of anti-corruption character education in junior high schools. In contrast, the methods used are lectures, question and answer methods, and simulations with film screenings about anti-corruption characters in schools. The results of this activity showed that of the 30 (thirty) OSIS administrators who attended this event, almost 99% of them knew that corruption was a violation of the law.

Sungai Pisang Village is a village that has only been accessible by smooth road roads in the past year in Padang City. Previously this village was only accessible by sea and by lousy road. This condition causes the Pisang River community to lag in socio-economic and health aspects. This activity aims to screen for worms in elementary school students in Sungai Pisang village because worms are closely related to environmental health and affect the quality of human resources experiencing growth and development. Screening for worms is carried out by examining fecal preparations. This activity also aims to check visual acuity in elementary students and make references for sharp vision correction to learn well. Visual acuity checks were carried out using a Snellen card. The results of the examination showed that 3/143 students had worms and 3/273 students had visual disturbances. Students with worms are recommended to go to the Puskesmas to be given deworming medicine, and students with visual impairments are facilitated for examination by an ophthalmologist and given glasses if needed.
Formation of platform economy of necessary needs based on energy economic equivalent
Authors:   Research Centre “NATURAL INFORMATIC”, National Supercomputer Technological Platform, Novosibirsk, Russia, Bryndin Evgeniy
Published: October 2021

Recently, many non-state money systems have appeared based on digital cryptocurrencies. The disadvantages of digital cryptocurrencies are the separation from real production, the inequality of participants, the lack of control by state bodies, and the security problem. Digital money becomes full-fledged only when it is connected with the real economy and financially secured. The author proposes the introduction of a material digital energy economic equivalent. Based on the digital energy of the economic equivalent, it is proposed to form a digital high-tech platform economy of healthy needs, like the economy of the future. Platform economy is an economic activity based on platforms, which are understood as online systems that provide comprehensive standard solutions for interaction between users, including commercial transactions and innovative solutions. It is proposed to measure the efficiency of the future economy by economic energy intensity. Energy intensity is represented by a certain amount of energy of economic equivalent, in accordance with the law of energy conservation. Reliance on a materially supported digital energy economic equivalent, as a new currency, makes a digital high-tech platform economy of healthy needs synergistic, efficient, sustainable, safe, ecological, open, controlled by society, without speculative operations, health supportive, accurately measured through digital energy intensity. Material digital energy intensity will avoid the speculative shortcomings of existing digital money systems. To this end, governments establish a procedure for regulating the energy economy with an economic equivalent, as an impact on public relations in order to streamline and stabilize them, in order to realize the necessary needs of society in accordance with the available resources. The status of an energy economic equivalent means recognition by the economic community as universal equivalent.
La nominación del sujeto masculino no heteronormativo en el francés común contemporáneo
Authors: Patiño Alzate Christian
Published: October 2021

Basándonos en la experiencia y la observación del francés común contemporáneo durante una estancia lingüística de casi tres años en París (como hispanohablante de origen colombiano), observamos el uso de un conjunto de nominaciones relacionadas con lo que se suele definir en el lenguaje común como la “homosexualidad masculina”. Nos interesamos en las prácticas de nominación que involucran a sujetos masculinos que no se encuentran inscritos, de alguna manera, dentro de la norma heterosexual socialmente impuesta. Después de definir los casos más comunes de la nominación del sujeto masculino no heteronormativo en el francés común contemporáneo, hemos optado por estudiar este fenómeno desde un ángulo “praxemático”, “pragmático”, y que apela a los “saberes epilingüísticos” y al “sentimiento lingüístico” de 50 hablantes de francés contemporáneo en Paris. Este ángulo de estudio nos permitió observar características fundamentales de este fenómeno, como lo son: la banalización de la nominación de los sujetos en mención, sexualización y patologización de las conductas no heteronormativas, el paralelismo entre extranjeros, mujeres, prostitutas y hombres homosexuales o afeminados, la influencia del inglés y la cultura estadounidense, la apropiación de algunas nominaciones para nombrarse a sí mismo, entre otros elementos que podrán verse en el análisis y la conclusión del presente artículo.
Género y estrato socioeconómico, ¿factores determinantes en el número y tipo de errores escritos del inglés como lengua extranjera?
Authors: Pardo Rodríguez María Victoria , Quiroz Herrera Gabriel Ángel
Published: October 2021

Este artículo presenta el análisis estadístico de los errores de escritura en un corpus de estudiantes de inglés como lengua extranjera (ILE) a nivel universitario. Se busca establecer si existe relación entre los principales errores de las composiciones escritas y dos factores sociodemográficos: género y estrato. Los participantes fueron clasificados en los niveles B1 y B2 según el Marco Común Europeo de Referencia (MCER) El corpus se compiló siguiendo los procedimientos de la Lingüística de Corpus Computacional (LCC) y los errores se analizaron conforme al método de análisis de errores y codificados de acuerdo con el sistema de anotación de errores de la Universidad de Lovaina versión 1.2. Según los hallazgos, los errores más prevalentes en hombres y mujeres pertenecen a las categorías Forma, Deletreado (FS), Artículo Gramatical (GA) y Léxico (LS). De igual forma, de acuerdo con los resultados el error con más prevalencia en el estrato 1 y 2 del nivel B2 es Artículo Gramatical (GA). En este mismo nivel, en los estratos 3, 4, 5 y 6 el error con más prevalencia es Léxico (LS). Se ofrece una vista general de los resultados que forman parte de una tesis doctoral.
La hipótesis en la lengua de señas colombiana (LSC)
Authors: Tovar Lionel Antonio , López Lorenzo
Published: October 2021

En este artículo se continúa con la exploración de las funciones del lenguaje académico en la lengua de señas colombiana (LSC), iniciada por los mismos autores. El propósito del estudio es presentar la estructura de la hipótesis en LSC, tal como aparece en textos producidos por informantes sordos durante discusiones metalingüísticas suscitadas a partir de textos escritos de hipótesis en español. Primero se presenta el sistema de la modalización de probabilidad y su estructura léxico-gramatical en español, así como el papel de la gestualidad en su expresión. Seguidamente se presenta la modalización de probabilidad en LSC y se dan ejemplos de textos de hipótesis producidos por los señantes, para ilustrar y analizar la léxico-gramática de esta función.
Compound nouns do not always fulfill the conjunction thesis: An analysis using the mental model theory
Authors: López-Astorga Miguel
Published: October 2021

This paper is intended to show that the properties classical logic attributes to conjunction are not always found in real compound nouns in natural language. This fact is described by means of several examples taken from different natural languages. The main conclusion is that perhaps a better option to understand human language and communicative phenomena is to assume a basically semantic approach with the mental model theory proposed as a more suitable alternative. This is because the fact that the logical properties that are not always present in real compound nouns is not considered a problem under the framework of this theory.
Characterising the late Quaternary facies stratigraphy of floodplains in South Africa
Authors: Grenfell S. , Grenfell M.
Published: October 2021

South African river floodplains and their alluvial deposits reflect a diversity of geological and geographical drivers. We use a genetic geomorphic classification system originally developed for dryland wetlands to characterise geomorphic processes and potential successions of sedimentary fill for South African floodplains. Using case studies from the literature, we consider differences between alluvial rivers and mixed bedrock-alluvial rivers in the context of macro-scale geomorphic setting, and evaluate the impact of the setting on floodplain persistence and potential as a palaeo-environmental archive. Sedimentary facies associations represented in South African floodplains, including lateral and oblique accretion, channel, channel infill, levee vertical accretion, floodplain vertical accretion and debris flow deposits, are also evaluated.

Floodplains of South Africa’s interior are typically mixed bedrock-alluvial as channel beds are set upon or close to bedrock and sediment thickness is limited. By contrast some floodplains in tectonic basin settings have sediment deposits exceeding 30 m in thickness. The resulting rivers are alluvial, and thus able to adjust their width, depth and slope to accommodate changes in discharge and sediment supply. Similarly, coastal floodplain rivers are alluvial due to downcutting during the last glacial maximum and subsequent sedimentary infilling as sea levels rose.

When considering the potential of floodplains as palaeoarchives of environmental change, two considerations emerge. First, floodplain stratigraphy is not a response to a single variable due to complex process-form feedbacks. Rather, floodplain stratigraphy is an outcome of both autogenic and allogenic processes. Second, most South African floodplains are zones of sediment recycling, and as such, preservation potential is typically low. Thus, although floodplain settings of the interior may be a few million years old, the sediment within them may be only thousands to tens of thousands of years old. Our review indicates that research has historically focused on meandering river and mixed bedrock-alluvial anabranching river floodplains, while understanding of other floodplain sub-types remains limited.
