Published: October 2022

Abstract. Riverine transport of particulate organic carbon (POC)
associated with terrigenous solids to the ocean has an important role in the
global carbon cycle. To advance our understanding of the source, transport,
and fate of fluvial POC from regional to global scales, databases of
riverine POC are needed, including elemental and isotope composition data
from contrasted river basins in terms of geomorphology, lithology, climate,
and anthropogenic pressure. Here, we present a new, open-access,
georeferenced, and global database called MOdern River archivEs of Particulate Organic Carbon (MOREPOC) version 1.1, featuring data on POC in suspended particulate matter (SPM) collected at 233 locations across 121 major river
systems. This database includes 3546 SPM data entries, among them 3053 with POC content, 3402 with stable carbon isotope (δ13C)
values, 2283 with radiocarbon activity (Δ14C) values, 1936
with total nitrogen content, and 299 with an aluminum-to-silicon ratio (Al / Si). The MOREPOC database aims at being used by the Earth system community to
build comprehensive and quantitative models for the mobilization,
alteration, and fate of terrestrial POC. The database is made available on
the Zenodo repository in machine-readable formats as a data table and GIS shapefile at https://doi.org/10.5281/zenodo.7055970 (Ke et al.,

Abstract. A historical dataset of river chemistry and discharge is presented for 140 monitoring sites along the United States East Coast, the Gulf of Mexico, and the West Coast from 1950 to 2020. The dataset, referred to here as River Chemistry for the U.S. Coast (RC4USCoast), is mostly derived from the Water Quality Database of the U.S. Geological Survey (USGS), but also includes river discharge from the USGS’s Surface-Water Monthly Statistics for the Nation and the U.S. Army Corps of Engineers. RC4USCoast provides monthly time series as well as long-term averaged monthly climatological patterns for twenty variables including alkalinity and dissolved inorganic carbon concentration. It is mainly intended as a data product for regional ocean biogeochemical models and carbon chemistry studies in the U.S. coastal regions. Here we present the method to derive RC4USCoast and briefly describe the river's carbonate chemistry patterns.
Yukon River incision drove organic carbon burial in the Bering Sea during global climate changes at 2.6 and 1 Ma

Published: October 2022

Abstract. River erosion affects the carbon cycle and thus climate by exporting terrigenous carbon to seafloor sediment and by nourishing CO2-consuming marine life. The Yukon River–Bering Sea system preserves rare source-to-sink records of these processes across profound changes in global climate during the past 5 million years (Ma). Here, we expand the terrestrial erosion record by dating terraces along the Charley River, Alaska, and explore linkages among previously published Yukon River
tributary incision chronologies and Bering Sea sedimentation. Cosmogenic
26Al/10Be isochron burial ages of Charley River terraces match previously documented central Yukon River tributary incision from 2.6 to 1.6 Ma during Pliocene–Pleistocene glacial expansion, and at 1.1 Ma during the 1.2–0.7 Ma Middle Pleistocene climate transition. Bering Sea sediments preserve 2–4-fold rate increases of Yukon River-derived continental detritus, terrestrial and marine organic carbon, and silicate microfossil deposition at 2.6–2.1 and 1.1–0.8 Ma. These tightly coupled records demonstrate elevated terrigenous nutrient and carbon export and concomitant Bering Sea productivity in response to climate-forced Yukon River incision. Carbon burial related to accelerated terrestrial erosion may contribute to CO2 drawdown across the Pliocene–Pleistocene and Middle Pleistocene climate transitions observed in many proxy records worldwide.
A new bootstrap technique to quantify uncertainty in estimates of ground surface temperature and ground heat flux histories from geothermal data
Authors: Cuesta-Valero Francisco José , Beltrami Hugo , Gruber Stephan , García-García Almudena , González-Rouco J. Fidel
Published: October 2022

Abstract. Estimates of the past thermal state of the land surface are crucial to assess the magnitude of current anthropogenic climate change as well as to assess the ability of Earth System Models (ESMs) to forecast the evolution of the climate near the ground, which is not included in standard meteorological records. Subsurface temperature reacts to long-term changes in surface energy balance – from decadal to millennial time scales – thus constituting an important record of the dynamics of the climate system that contributes, with low-frequency information, to proxy-based paleoclimatic reconstructions. Broadly used techniques to retrieve past temperature and heat flux histories from subsurface temperature profiles based on a singular value decomposition (SVD) algorithm were able to provide robust global estimates for the last millennium, but the approaches used to derive the corresponding 95 % confidence interval were wrong from a statistical point of view in addition to being difficult to interpret. To alleviate the lack of a meaningful framework for estimating uncertainties in past temperature and heat flux histories at regional and global scales, we combine a new bootstrapping sampling strategy with the broadly used SVD algorithm and assess its performance against the original SVD technique and another technique based on generating perturbed parameter ensembles of inversions. The new bootstrap approach is able to reproduce the prescribed surface temperature series used to derive an artificial profile. Bootstrap results are also in agreement with the global mean surface temperature history and the global mean heat flux history retrieved in previous studies. Furthermore, the new bootstrap technique provides a meaningful uncertainty range for the inversion of large sets of subsurface temperature profiles. We suggest the use of this new approach particularly for aggregating results from a number of individual profiles, and to this end, we release the programs used to derive all inversions in this study as a suite of codes labeled CIBOR v1: Codes for Inverting BORholes, version 1.
Understanding the diurnal cycle of land–atmosphere interactions from flux site observations
Authors: Seo Eunkyo , Dirmeyer Paul A.
Published: October 2022

Abstract. Land–atmosphere interactions have been investigated at
daily or longer timescales due to limited data availability and large
errors for measuring high-frequency variations. Yet coupling at the
subdaily timescale is characterized by the diurnal cycle of incoming solar
radiation and surface fluxes. Based on flux tower observations, this study
investigates the climatology of observed land–atmosphere interactions on
subdaily timescales during the warm season. Process-based multivariate
metrics are employed to quantitatively measure segmented coupling processes,
and mixing diagrams are adopted to demonstrate the integrative moist and
thermal energy budget evolution in the atmospheric mixed layer. The land,
atmosphere, and combined couplings for the entire daily mean, midday, and
midnight periods show different situations to which surface latent and sensible heat
fluxes are relevant, and they also reveal the climate sensitivity to soil
moisture and surface air temperature. The 24 h coevolution of the moist
and thermal energy within the boundary layer traces a particular path on
mixing diagrams, exhibiting different degrees of asymmetry (time shifts) in
water- and energy-limited locations. Water- and energy-limited processes
also show opposing long tails of low humidity during the daytime and
nighttime, related to the impact on land and atmospheric couplings of
latent heat flux and other diabatic processes like radiative cooling. This
study illustrates the necessity of considering the entire diurnal cycle to
understand land–atmosphere coupling processes comprehensively in
observations and models.

Published: October 2022

Abstract. The soil inorganic carbon (SIC) pool is a major component of soil carbon (C) pools, and clarifying the predictors of SIC stock is urgent for decreasing soil C losses and maintaining soil health and ecosystem functions. However, the drivers and their relative effects on the SIC stock at different soil depths remain largely unexplored. Here, we conducted a large-scale sampling to investigate the effects and relative contributions of abiotic (climate and soil) and biotic (plant and microbe) drivers on the SIC stock between topsoils (0–10 cm) and subsoils (20–30 cm) across Tibetan alpine grasslands. Results showed that the SIC stock had no significant differences between the topsoil and subsoil. The SIC stock showed a significant increase with altitude, pH and sand proportion, but declined with mean annual precipitation (MAP), plant aboveground biomass (PAB), plant coverage (PC), root biomass (RB), available nitrogen (AN), microbial biomass carbon (MBC), and bacterial abundance (BA) and fungal gene abundance (FA). For both soil layers, biotic factors had larger effects on the SIC stock than abiotic factors did. However, the relative importance of these determinants varied with soil depth, with the effects of plant and microbial variables on SIC stock weakening with soil depth, whereas the importance of climatic and edaphic variables increased with soil depth. Specifically, BA, FA and PC played dominant roles in regulating SIC stock in the topsoil, while soil pH contributed largely to the variation of SIC stock in the subsoil. Our findings highlight differential drivers over SIC stock with soil depth, which should be considered in biogeochemical models for better simulating and predicting SIC dynamics and its feedbacks to environmental changes.

Published: October 2022

Abstract. This paper describes the results of a wave tank test campaign of a 1/49 scaled SATH 10 MW floating platform. The software-in-the-loop (SiL) hybrid method was used to include the wind turbine thrust and the in-plane rotor moments. Experimental results are compared with a numerical model developed in OpenFAST of the floating wind turbine. The tank test campaign was carried out in the scaled model tested at the deep ocean basin from the Lir National Ocean Test Facility at Cork, Ireland. This floating substructure design was adapted by Saitec to support the 10 MW wind turbine within the ARCWIND project (Adaptation and Implementation of Floating Wind Energy Conversion Technology for the Atlantic Region) with the aim of withstanding the environmental conditions of the European Atlantic Area region. CENER provided the wind turbine controller specially designed for the SATH 10 MW configuration. A description of the experimental setup, force actuator configuration and the numeric aerodynamic parameters is provided in this work. The most relevant experimental results under wind and wave loading are shown in time series and frequency domain. The influence of the submerged geometry variations in the pitch natural frequency is discussed. The paper shows the simulation of a case with rated wind speed, where the tilted geometry for the computation of the hydrostatic and hydrodynamic properties of the submerged substructure is considered. This case provides a better agreement of the pitch natural frequency with the experiments than an equivalent simulation using the undisplaced geometry mesh for the computation of the hydrodynamic and hydrostatic properties.
Open publishing and the value of access
Authors:   , Thiel Jessica
Published: October 2022

There are fundamental problems with the educational publishing market; textbooks and other education resources cost a significant amount of money to access and are governed by restrictions which limit how they can be accessed, used, and reused. This thesis investigates open publishing in higher education and offers an alternative to how educational materials (particularly textbooks), can sustainably be produced and managed. The research further considers how the broader adoption of open publishing in higher education could positively influence the way publishing in education considers systemic issues such as equity, diversity, and inclusion, and ultimately, provide opportunities to support human development.

Published: October 2022

In order to verify the degree of difficulty and discrimination capacity of an evaluation instrument, a group of 124 students of a course of statistics of the National University of Cordoba, Argentina, were examined. To do this, a questionnaire was implemented on the Moodle platform, consisting of 21 questions about inferential statistics and was answered online. The instrument was validated by applying item response theory (IRT) models, with binary response variables, detecting questions with different degrees of difficulty and discrimination. The results indicate that those questions that contribute to the construct (knowledge in statistics), that have average difficulty and are the ones that segregate more among the students were the appropriate to evaluate.

Teaching Concepts of Diversity, Equity, Inclusion and Social Responsibility Through Elementary Statistics
Authors:   Slippery Rock University of Pennsylvania, Asher Jana
Published: October 2022

The use of antiracist and critical pedagogy has become a growing movement across higher education within the United States but has not been generally considered within STEM curricula. Similarly, community-engaged learning, a decades-old movement in civics learning within higher education, has made relatively little headway in STEM coursework. These two movements, however, complement each other, and both have much to contribute to how we teach statistics. Over the past five years, I have leveraged these two approaches to civic learning to incorporate themes around diversity, equity, and inclusion into my elementary statistics class. This paper outlines those efforts and provides a preliminary analysis of student-provided course evaluation data.
Using Data for Good: A Matter of Geography
Authors:   TERC, Rubin Andee
Published: October 2022

The purpose of this research is to learn how youth aged 11–14 understand highly aggregated data about social and economic conditions, especially related to the United Nations Sustainable Development Goals. We designed an after-school program that introduces students to data broadly in the context of “using data for social good.” Using CODAP, an educational data visualization tool, students explore data about countries’ health and education indicators. We observe that youth are highly engaged with these data yet sometimes struggle to make sense of the aggregate values that hide variability within countries. Using examples from student projects, this paper reports preliminary findings about how youth analyze data aggregated by governmental entities such as countries, states, or cities.

There have been intensive research efforts to improve Bayesian reasoning over the last 25 years. Much of this research focuses solely on improving performance on Bayesian tasks. In addition to performance, however, it is also important to establish an understanding of the effect on the positive predictive value when parameters of Bayesian formula are changed. We call this ability “covariation” in Bayesian tasks. To this end, training courses were developed to support understanding of covariation, based on strategies that have been proven helpful by previous studies concerning performance, using: (a) natural frequencies and (b) visualisations, i.e., double trees and unit squares. Results of a comparative study in a pre-, post-, and follow-up test design show that the developed training courses can improve understanding of covariation.
A Transparent, Simple AI Tool for Constructing Efficient and Robust Fast and Frugal Trees for Classification Under Risk
Authors:   Ludwigsburg University of Education, Martignon Laura , Engel Joachim ,   Ludwigsburg University of Education, Erickson Tim ,   Eeps Media
Published: October 2022

Artificial Intelligence (AI) has produced extremely efficient and effective classification and decision “machines” that learn from given data sets and generalize well to unknown data. These are mostly celebrated tools produced by methodologies of machine learning. There is a drawback, though, namely their lack of transparency in construction. Agents often ignore the construction steps and use them as black-box algorithms. We exhibit simple and transparent steps for creating robust and yet simple heuristics for classification based on the AI tool ARBOR. We also claim that these transparent classifiers compete well against powerful machines, especially when training sets are small.

Patients need to be informed correctly and comprehensibly about the implications of their medical test results. Reasoning in such situations, where, for example, a medical test result is used to make inferences on a particular disease, is called Bayesian reasoning. Prior research mostly concentrated on the ability to correctly calculate risks in Bayesian situations (so-called performance) and repeatedly demonstrated that performance is very low—even among medical experts. The need to also study communication within Bayesian situations has been brought forward. Here, we broaden the focus of Bayesian reasoning and present first insights into a study where medical students participated in a training course on the aspect of performance and show that this already improves the ability to judge doctor–patient communication within Bayesian situations.
Teaching Statistics in Context: Effects of Statistics History on Student Learning
Authors:   University College London, Suarez-Rivera Catalina , Langan Dean ,   University College London
Published: October 2022

Students often learn statistical techniques and theory without historical context. Would integrating history support student experiences and lead to improved learning? An online randomized cross-over experiment with 135 participants examined (a) comprehension of statistical concepts (Fisher’s exact test and Pearson’s correlation) after watching short videos with and without historical context, and (b) overall attitudes towards including the history of statistics in live/online lectures. Self-reported viewing habits and comprehension were comparable in participants who watched the videos with and without history. Despite this, participants generally had a positive attitude towards its inclusion. Likewise, at least three times as many participants agreed that videos with historical context were preferred, important, and worth the time.
An Approach to a Proposal of Inferential Levels of Reasoning
Authors:   Universidad de Los Lagos, Lugo-Armenta Jesús Guadalupe , Pino-Fan Luis ,   Universidad de Los Lagos
Published: October 2022

In statistical education it has been emphasized to gradually promote inferential reasoning using results obtained in the last two decades on the exploration and promotion of informal inferential reasoning and connecting it with the key ideas of formal inferential reasoning. In this paper we present a general proposal of progressive levels of inferential reasoning, from previous proposals of levels of inferential reasoning on the chi-square and t-Student statistics. To this end, it has resorted to epistemological criteria retrieved through a historical-epistemological study on the aforementioned statistics and the didactic guidelines given by the statistical education literature. The proposed levels can be used both to characterize the inferential reasoning of students and teachers, and in the design of activities that promote inferential reasoning. En Educación Estadística se ha enfatizado promover gradualmente el razonamiento inferencial utilizando resultados obtenidos en las últimas dos décadas sobre la exploración y promoción del razonamiento inferencial informal y conectándolo con las ideas clave del razonamiento inferencial formal. En este trabajo presentamos una propuesta general de niveles progresivos de razonamiento inferencial, a partir de propuestas previas de niveles de razonamiento inferencial sobre los estadísticos chi-cuadrada y t-Student. Para ello, se ha recurrido a criterios epistemológicos recuperados mediante un estudio histórico-epistemológico sobre los estadísticos mencionados y a las directrices didácticas otorgadas por la literatura de Educación Estadística. Los niveles propuestos pueden utilizarse tanto para caracterizar el razonamiento inferencial de estudiantes y profesores, como en el diseño de actividades que promuevan el razonamiento inferencial.
Brody and Jamie’s Colleague: The Difference in Confidence Interval Estimators and Estimates
Authors:   Appalachian State University, Roland Kristen , Kaplan Jennifer ,   Middle Tennessee State University
Published: October 2022

In an ever-increasing data-driven world, understanding and describing uncertainty around statistical results have become increasingly more important. Although describing uncertainty can take many forms, recent statements from professional associations (e.g., American Statistical Association) have suggested an increased use of confidence intervals. The calculation of a confidence interval (CI) is fairly straightforward, but the interpretation of a frequentist CI is not. This paper presents a case that demonstrates a potentially important connection among the CI estimator, estimate, and the coverage probability to gain a deep understanding of the meaning of the word confident in the interpretation of a CI. The case provides evidence of the connections among the coverage probability, long-run interpretation of a CI, and the interpretation of a CI that may support robust knowledge.

Dear friends,

In June we moved to open editorial software that is hosted by Ljubljana University. We are still adapting to this new address and the new way of work. We apologise for any inconvenience that this move has created and hope to get everything running smoothly by the end of this year.

Please note that our new address is

There has been news from the Web of Science recently: our journal has been evaluated in the Journal Citations Reports. The full report is available at the end of the Journal. As far as we understand it, a report in the JCR is the first step towards calculating the impact factor of a journal. Our results are not spectacular, we will be placed in the 4th quarter (Q4), but to be placed alone is a huge success on its own. Perhaps our articles are like wine, the older they are the more citations they gain.

By the way, in SCOPUS by SNIP we are in the third quarter, very close to the second.

We are still experiencing problems with reviewers, as unfortunately many have no time. Allow me to appeal to you to please help out! We are running a very specialised journal and have access to only limited numbers of researchers. Let us all make an effort to be part of the prominent scientific community on the Web of Science and in SCOPUS!

This issue is mostly dedicated to rhythmic gymnastics with six articles focusing on it. The rest are articles on artistic gymnastics and physical education. Authors are again from all around the world: Tunisia, Oman, United Kingdom, Ukraine, Bulgaria, Brazil, Czechia, Turkey, Croatia, USA and Greece.  

The first World Championship in parkour in Japan was historic. It would be great  to have a paper on this new gymnastics sport discipline.

Anton Gajdoš prepared his 25rd short historical note introducing Shigeru Kasamatsu from Japan.

EFFECT OF ASSEMBLÉ-STEP ON KINETIC AND KINEMATIC PARAMETERS OF STAG RING LEAPS WITH AND WITHOUT THROW-CATCH OF THE BALL IN RHYTHMIC GYMNASTICS
Authors: Akkari-Ghazouani Hounaida , Amara Samiha , Jemni Monem , Chtara Mokhtar , Mkaouer Bessem
Published: October 2022

This study was conducted to compare the kinetic and kinematic factors of stag ring leap with and without throwing the ball using the two-leg take-off ballet-step “Assemblé” between three different modes in rhythmic gymnastics (RG). Seven members of the Tunisian RG national team (age 18.71±2.69 years; height 1.67±0.04 m; weight 58.43±4.03 kg) took part in this study. A kinetic and kinematic analysis of three stag ring leap execution modes (i.e., assemblé stag ring leap without ball, throw ball assemblé stag ring leap and assemblé throw ball stag ring leap) using two cameras on a specially designed floor carpet where a force plate was integrated was conducted. The result showed that the vertical component of force, the rate of force development, the angle of split legs and the horizontal and vertical velocity were significantly different (P<0.01). In this study, it was found that while performing the stag ring leap element, gymnasts present the highest value in both kinetic and kinematic parameters when throwing the ball during the jump (i.e., assemblé throw ball stag ring leap).  In light of the obtained results, it is recommended that coaches start working with gymnasts on the throws during the jump from their youngest age, as this could help them attain the optimal performances in competition.

Published: October 2022

Involving people in physical activity or sport provides some health-related benefits and has a positive effect on their quality of life (QoL). However, high level athletes experience anxiety to cope with the high demands of the sport. The purpose of the study was to assess the QοL, level of anxiety (STAI) and level of depression (BDI) among former artistic gymnasts, former athletes from other gymnastics sports (acrobatic, rhythmic, gymnastics for all) and non-athletes. Secondly, it aimed to investigate if there are gender differences within the groups on the aforementioned variables. 114 healthy people (75 women and 39 men) were involved in the present study with a mean age 27.11 ± 9.92 years. The sample was divided into 3 different groups (1st group: 39 former artistic gymnasts (FAG);  2nd group: 53 former gymnasts from other gymnastic sports (GOS), and 3rd group: 22 non-athletes (CG). Participants were asked to complete three different questionnaires in order to assess their QoL, STAI, and BDI. Statistical analysis showed no significant differences on QοL and STAI, whoever a statistically significant difference was found between groups on BDI (p <.05). No main effect was found on gender. Further, results revealed that former gymnasts, regardless of the type of sport, have better QoL, lower level of STAI and BDI compared to non-athletes. In conclusion, former gymnasts, even after years of absence from the sport, report better QoL, and have a lower level of STAI and BDI than non-athletes.

Published: October 2022

The aim of this study was to examine the combined effect of mental imagery as well as visualization on performance, self-confidence, and self-report during the performance of the standing salto backward. Eighteen gymnasts (age 22.11 ± 1.71 years) voluntarily participated in this study. Once the warm-up was completed, subjects performed a standing salto backward tucked on the force-plate to determine the baseline performance before each experimental session. Subsequently, subjects were given specific intervention instructions and were asked to perform the standing salto backward tucked to the best of their ability. Participants were asked to engage in two mental strategies namely mental imagery and visualization for 1 min just before performing (Standing salto backward tucked). The results of the present study show that the combined mental simulation (MI and V), generate a potential improvement in performance during the execution of the standing salto backward as well as self-confidence and self-evaluation.

Objective: To compare the effectiveness of aromatherapy with lavender essential oil (EO) versus an EO synergy on psycho-emotional symptoms and fatigue of nursing professionals in the COVID-19 setting. Materials and Methods: This is a quasi-experimental pilot study conducted in 2020. The professionals were randomized in Group 1 — lavender, and in Group 2 — lavender and other EOs synergy. The instruments were validated in Brazil, namely the Self-Reporting Questionnaire (SRQ-20) and the Fatigue Pictogram, which were applied at three moments: before the intervention, after 21 days of intervention, and three weeks after the end of the intervention follow-up. The data were evaluated using Pearson’s x2 test or Fisher’s exact test (dichotomous variables) and Student’s t-test or Mann-Whitney test (continuous variables). Results: A total of 18 professionals participated, and both groups presented improved SRQ-20 scores (p < 0.010), which was maintained in the follow-up for Group 1 compared to the pre-intervention moment (p = 0.033). There was a significant decrease in fatigue in professionals in both groups (p = 0.010), but no difference was observed in the improvement of the impact of fatigue on daily life. Conclusions: There was a reduction in psycho-emotional symptoms and fatigue in nursing professionals who used aromatherapy during the COVID-19 pandemic in both groups.
‘Me encanta mi trabajo, pero es un trabajo’: creadores de contenido en redes sociales e imaginarios laborales
Authors: Oliva Mercè
Published: October 2022

El objetivo de este artículo es analizar los discursos de los creadores de contenido en redes sociales (youtubers, streamers, instagramers, influencers) sobre su propio trabajo para entender cómo personifican, conectan y ayudan a construir los imaginarios laborales contemporáneos. Diversos autores han señalado cómo el mundo del trabajo ha sufrido importantes transformaciones que suponen un avance en la precarización, casualización e intermitencia en el ámbito laboral. Los creadores en redes sociales se presentan como ejemplos de este nuevo mundo del trabajo, en el que se ensalza la flexibilidad y la búsqueda de la realización personal como sustituto a la remuneración económica. El presente artículo quiere responder a las siguientes preguntas: ¿cómo representan los creadores de contenido digitales y los medios de comunicación tradicionales su actividad profesional?; ¿cómo se relacionan estos discursos con los imaginarios laborales contemporáneos? Para ello, se analiza cualitativamente una muestra de cuarenta videos publicados entre 2015 y 2022 en los que once creadores de contenido españoles hablan explícitamente sobre su trabajo. A través de un análisis cualitativo temático, se han identificado patrones recurrentes de significado. El análisis muestra que si bien inicialmente los creadores de contenido hablan de su labor a través de discursos entusiastas que subrayan su “pasión por el trabajo”, en los últimos años encontramos discursos más contradictorios. Los creadores hablan abiertamente sobre el coste de su trabajo, caracterizado por la intensificación, la confusión entre vida personal y profesional y el trabajo emocional.

Introduction: The human ear is the most defining feature of the face. The anatomical structure of the external ear is utilized for personal identification of living subjects in relation to criminal activity. Aim: To evaluate and compare the uniqueness of morphological and biometric variations of both ears for individualization among subpopulations of India in states of Punjab, Haryana and Jammu and Kashmir. To determine the Morphology and Biometrics of both ears in both male and female populations of Punjab, Haryana and Jammu and Kashmir. To study and compare the Ear Prints of population of three states and find a correlation between them. Materials and Methods: The present study was carried out randomly selected 120 students; 40 from Punjab (P), 40 from Haryana (H) and 40 from Jammu and Kashmir (J and K) population zones of India out of which 20 subjects were males and 20 were females from each population group of age between 18 to 25 years. Nine ear parameters were recorded twice using digital vernier calipers by single investigator and two indices (Ear Index and Lobule Index) were calculated for both the ears. Morphological ear shapes and lobule attachment were also noted.Chi-square test and one way ANOVA tests were performed on cross tabulations followed by turkey HSD test to evaluate significant relationship between both genders in three populations. Results: The highest total ear length in both ears (left and right) was noted in females of Haryana; followed by Punjab and J and K. Out of the total sample size, 60.41% ear lobes were free and 39.59% were attached. 100% Ear symmetry was seen in both ears among both genders of Haryana population and Oval ear shape was observed mostly followed by round, rectangular and triangular in Punjab and Haryana populations and no triangular morphology was observed in J and K population. The highest Ear Index in left ear was seen in both genders in population of Punjab whereas in that of right ear, highest ear index was seen in females of Haryana and males of Punjab population. The highest lobule index was noted in both the ears of females as well as males in Haryana population. Conclusion: The present study results of morphological examination and morpholometric variations of human ears can be used as supportive evidence as having a role in forensic sciences by the identification of landmarks variations in different ethnic groups.
