Published: August 2024

Android is an operating system whose capabilities continue to increase from year to year. The capabilities of Android currently match the capabilities of a computer. Not only limited to ordinary computers, what a server computer can do can now be done on Android, including making Android a web server. So it is possible for people who have Android to have their own web server. The problem that arises is that the web server on Android cannot be accessed directly via the internet. Cellular operators do not provide Public IP to their customers, so a way is needed so that the Android web server can be accessed on the internet, one of which is by using Virtual Private Network (VPN) technology. The aim of this research is to make the web server on Android accessible on the internet. The method used is to combine a Virtual Private Server (VPS) and Android using VPN. The research results showed that VPN can be a bridge so that the web server on Android can be accessed from the internet.

Published: August 2024

Abstract. Wind reversals resulting in southerly flow along the California coast are not well understood in terms of how aerosol and cloud characteristics change. This gap is addressed using airborne field measurements enhanced with data from spaceborne remote sensing (Moderate Resolution Imaging Spectroradiometer), surface stations (Interagency Monitoring of Protected Visual Environments), and models (Navy Aerosol Analysis and Prediction System and Coupled Ocean–Atmosphere Mesoscale Prediction System), with a focus on submicron and supermicron aerosol, as well as cloud microphysical variables: cloud droplet number concentration (Nd), cloud optical thickness (COT), and cloud droplet effective radius (re). Southerly flow coincided with higher values of submicron aerosol concentration (Na) and mass concentrations of species representative of fine-aerosol pollution (NO3- and nss-SO42-) as well as shipping and continental emissions (V, oxalate, NH4+, Ni, OC, and EC). Supermicron Na did not change; however, heightened levels of acidic species in southerly flow coincided with reduced Cl− : Na+, suggestive of Cl− depletion in salt particles. Clouds responded correspondingly in southerly flow, with more acidic cloud water and higher levels of similar species as in the aerosol phase (e.g., NO3-, nss-SO42-, NH4+, V), along with elevated values of Nd and COT and reduced re during campaigns with similar cloud liquid water paths. Case study flights help to visualize offshore pollution gradients and highlight the sensitivity of the results to the presence of widespread smoke coverage including how associated plumes have enhanced supermicron Na. These results have implications for aerosol–cloud interactions during wind reversals and have relevance for weather, public welfare, and aviation.
The lifetimes and potential change in planetary albedo owing to the oxidation of organic films extracted from atmospheric aerosol by hydroyxl (OH) radical oxidation at the air-water interface of aerosol particles

Published: August 2024

Abstract. Water insoluble organic material extracted from atmospheric aerosol samples collected in urban (Royal Holloway, University of London, UK) and remote (Halley, Antarctica) locations were shown to form stable thin films at an air-water interface, these organic films reacted quickly with gas-phase OH radicals which may impact planetary albedo. The x-ray reflectivity measurements additionally indicate that the film may be consistent with having a structure with increased electron density of film molecules towards the water, suggesting amphiphilic behaviour. Bimolecular rate constants for gas-phase OH radical oxidation of urban or remote aerosol extracts were typically of the order ∼1010 cm3 molecule−1 s−1, giving atmospheric lifetimes of the film with respect to gas-phase OH radical oxidation of minutes at typical atmospheric OH radical concentrations. Kinetic modelling of core-shell droplet dynamics suggests film lifetime of a few minutes, depending on ambient OH radical mixing ratio. Modelling the oxidation kinetics with KM SUB suggests half-lives of minutes to an hour and values of ksurf of ∼ 2 × 10−7 and ∼ 5 × 10−5 cm2 s−1 for urban and remote aerosol film extracts respectively. The lifetimes and half-lives calculated at typical OH atmospheric ambient mixing ratios are smaller than the typical residence time of atmospheric aerosols and thus oxidation of organic material should be considered in atmospheric modelling. Thin organic films at the air-water interface of atmospheric aerosol or cloud droplets may alter the light scattering properties of the aerosol. X-ray reflectivity measurements of atmospheric aerosol film material at the air-water interface resulted in calculated film thickness values to be either ∼10 Å or ∼17 Å for remote or urban aerosol extracts respectively and oxidation did not remove the films completely. One dimensional radiative transfer-modelling suggest the oxidation of thin organic films on atmospheric particles by OH radicals may reduce the planetary albedo by a small, but potentially significant amount.
Consistent increase in East Asian Summer Monsoon rainfall and its variability under climate change over China in CMIP6
Authors: Katzenberger Anja , Levermann Anders
Published: August 2024

Abstract. The East Asian Monsoon (EAM) dominates the climate over the densely populated region of eastern China and adjacent regions and therefore influences a fifth of the world's population. Thus, it is highly relevant to assess the changes in the central characteristics of the East Asian Summer Monsoon (EASM) under future warming in the latest generation of coupled climate models of the Coupled Model Intercomparison Project Phase 6 (CMIP6). We apply a set of selection criteria to 34 CMIP6 models to identify the six best performing (TOP6) models that best capture the EASM in the reference period 1995–2014. All of these models project an increase in June–August rainfall independent of the underlying emission scenario. The multi-model mean increase is 16.5 % under SSP5-8.5, 11.8 % under SSP3-7.0, 12.7 % under SSP2-4.5 and 9.3 % under SSP1-2.6 in the period 2081–2100 compared to 1995–2014. For China, the projected monsoon increase is slightly higher (12.6 % under SSP1-2.6 and 18.1 % under SSP5-8.5). The EASM rainfall will particularly intensify in southeastern China, Taiwan and North Korea. The multi-model mean indicates a linear relationship of the EASM rainfall depending on the global mean temperature that is relatively independent of the underlying scenario: per degree of global warming, the rainfall is projected to increase by 0.17 mm d−1, which refers to 3.1 % of rainfall in the reference period. It is thus predominately showing a “wet regions get wetter” pattern. The changes in the wind fields in the region are relatively small indicating the minor importance of dynamic factors, while pointing towards thermodynamic factors as responsible for the rainfall increase. The interannual variability is also robustly projected to increase between 17.6 % under SSP1-2.6 and 23.8 % under SSP5-8.5 in the multi-model mean between 2051–2100 and 1965–2014. Comparing the same periods, extremely wet seasons are projected to occur 7 times more often under SSP5-8.5.
Numerical stabilization methods for level-set-based ice front migration
Authors: Cheng Gong , Morlighem Mathieu , Gudmundsson G. Hilmar
Published: August 2024

Abstract. Numerical modeling of ice sheet dynamics is a critical tool for projecting future sea level rise. Among all the processes responsible for the loss of mass of the ice sheets, enhanced ice discharge triggered by the retreat of marine-terminating glaciers is one of the key drivers. Numerical models of ice sheet flow are therefore required to include ice front migration in order to reproduce today's mass loss and to be able to predict their future. However, the discontinuous nature of calving poses a significant numerical challenge for accurately capturing the motion of the ice front. In this study, we explore different stabilization techniques combined with varying reinitialization strategies to enhance the numerical stability and accuracy of solving the level-set function, which tracks the position of the ice front. Through rigorous testing on an idealized domain with a semicircular and a straight-line ice front, including scenarios with diverse front velocities, we assess the performance of these techniques. The findings contribute to advancing our ability to model ice sheet dynamics, specifically calving processes, and provide valuable insights into the most effective strategies for simulating and tracking the motion of the ice front.

Abstract. Restoring hydrological functions affected by economic development trajectories faces social and economic challenges. Given that stakeholders often only have a partial understanding of functioning socio-hydrological systems, it is expected that knowledge sharing will help them to become more aware of the consequences of their land use choices and options to manage water collectively. This facilitates the collective learning tools needed to represent the essential social and technical aspects of a socio-hydrological system in simple terms. However, data-driven simplification can lead to very site-specific models that are difficult to adapt to different conditions. To address these issues, this study aims to develop a highly adaptable serious game based on process understanding to make it easily applicable to any situation and to facilitate co-learning among stakeholders regarding complex socio-hydrological problems. We developed and tested a serious game that revolves around a simple water balance and economic accounting, with environmental and financial consequences for land users. The game is based on process understanding of the system, allowing for both relevant site specificity and generic replicability. Here, we describe the development of the Water: Use, Resources and Sustainability (H2Ours) game and explore its capacity to visualise, discuss and explore issues at the landscape level. The H2Ours game was designed using a combination of the Actors, Resources, Dynamics and Interaction (ARDI) and Drivers, Pressure, State, Impact and Responses (DPSIR) frameworks. The design steps for constructing the game led to a generic version and two localised versions for two different landscapes in Indonesia: a mountain slope to lowland paddy landscape impacting groundwater availability in East Java and a peatland with drainage rewetting, oil palm conversion and fire as issues triggering responses in West Kalimantan. Based on an evaluation referring to credibility, salience and legitimacy criteria, the H2Ours game met its purpose as a tool for knowledge transfer, learning and action triggering. We discuss the steps that can lead to re-designing and adaptation of the game to other landscapes and their policy-relevant issues.
Distribution of two notodendrodid foraminiferal congeners in McMurdo Sound, Antarctica: an example of extreme regional endemism?

Published: August 2024

Abstract. We used morphological and molecular surveys to determine the presence or absence of Notodendrodes antarctikos and its congener, Notodendrodes hyalinosphaira, at diverse sites within McMurdo Sound, Antarctica. Morphological surveys were performed using shipboard box-core sampling, as well as handheld coring and visual inspection by divers in shallow (< 23 m) waters. Concurrent molecular analyses were performed using species- and genus-specific PCR primers on environmental DNA extracts. Both survey methods show that N. hyalinosphaira is widely distributed in the region but that N. antarctikos was not detected outside its originally reported range. The survey methods show complementary strengths and weaknesses, with morphological detection being more sensitive in areas where large and distinctive adult forms are present and with molecular detection being more effective for identification of presumed juvenile or propagule stages. Our results suggest that N. antarctikos is a highly endemic protist and may have one of the most restricted ranges ever reported for an Antarctic organism.
Water depth estimate and flood extent enhancement for satellite-based inundation maps
Authors: Betterle Andrea , Salamon Peter
Published: August 2024

Abstract. Floods are extreme hydrological events that can reshape the landscape, transform entire ecosystems and alter the relationship between living organisms and the surrounding environment. Every year, fluvial and coastal floods claim thousands of human lives and cause enormous direct damages and inestimable indirect losses, particularly in less developed and more vulnerable regions. Monitoring the spatiotemporal evolution of floods is fundamental to reducing their devastating consequences. Observing floods from space can make the difference: from this distant vantage point it is possible to monitor vast areas consistently, and, by leveraging multiple sensors on different satellites, it is possible to acquire a comprehensive overview on the evolution of floods at a large scale. Synthetic aperture radar (SAR) sensors, in particular, have proven extremely effective for flood monitoring, as they can operate day and night and in all weather conditions, with a highly discriminatory power. On the other hand, SAR sensors are unable to reliably detect water in some cases, the most critical being urban areas. Furthermore, flood water depth – which is a fundamental variable for emergency response and impact calculations – cannot be estimated remotely. In order to address such limitations, this study proposes a framework for estimating flood water depths and enhancing flood delineations, based on readily available topographical data. The methodology is specifically designed to accommodate, as additional inputs, masks delineating water bodies and/or no-data areas. In particular, the method relies on simple morphological arguments to expand flooded areas into no-data regions and to estimate water depths based on the terrain elevation of the boundaries between flooded and non-flooded areas. The underlying algorithm – named FLEXTH – is provided as Python code and is designed to run in an unsupervised mode in a reasonable time over areas of several hundred thousand square kilometers. This new tool aims to quantify and ultimately to reduce the impacts of floods, especially when used in synergy with the recently released Global Flood Monitoring product of the Copernicus Emergency Management Service.

Abstract. Snow provides critical water resources for billions of people, making the remote sensing of snow water equivalent (SWE) a highly prioritized endeavor, particularly given ongoing climate change impacts. Synthetic aperture radar (SAR) is a promising method for remote sensing of SWE because radar penetrates snow, and SAR interferometry (InSAR) can be used to estimate changes in SWE (ΔSWE) between SAR acquisitions. We calculated ΔSWE retrievals from 10 NASA L-band (1–2 GHz, ∼25 cm wavelength) uninhabited aerial vehicle SAR (UAVSAR) acquisitions covering a ∼640 km2 swath in northern Colorado during the winters of 2020 and 2021. UAVSAR acquisitions coincided with ∼117 mm of accumulation in 2020 and ∼282 mm of accumulation in 2021. ΔSWE retrievals were evaluated against measurements of SWE from repeat ground-penetrating radar (GPR) and terrestrial lidar scans (TLSs) collected during the NASA SnowEx time series campaigns at two field sites (total area =∼0.2 km2) as well as SWE measurements from seven automated stations distributed throughout the UAVSAR swath. For single InSAR pairs, UAVSAR ΔSWE retrievals yielded an overall r of 0.72–0.79 and an RMSE of 19–22 mm when compared with TLS and GPR ΔSWE retrievals. UAVSAR ΔSWE showed some scatter with ΔSWE measured at automated stations for both study years, but cumulative UAVSAR SWE yielded a r of 0.92 and an RMSE of 42 mm when compared to total SWE measured by the stations. Further, UAVSAR ΔSWE RMSEs differed by <10 mm for coherences (i.e., the complex interferometric coherence) of 0.10 to 0.90, suggesting that coherence has only a small influence on the ΔSWE retrieval accuracy. Given the evaluations presented here and in other recent studies, the upcoming NASA-ISRO SAR (NISAR) satellite mission, with a 12 d revisit period, offers an exciting opportunity to apply this methodology globally.

Published: August 2024

Foam rolling have gained popularity among elite athletes, but the effect of the speed parameter of foam rolling has not yet been determined. Our objective was to investigate the impact of different application speeds of foam roller on the mechanical properties of the quadriceps femoris muscle. Eighteen male professional basketball athletes (age 23 ± 4 years, body mass index 24.43 ± 1.59 kg/m2) participated in this study. We used a crossover design to randomize the order of the treatment speeds (30 beats per minute-FAST, 15 beats per minute-SLOW, and a self-determined speed-SELF) with a one-week washout period between each session. We measured dominant quadriceps femoris muscle tone, elasticity, and stiffness using the Myoton device before and after the interventions. We found that the average rate for SELF was 33 ± 10 beats per minute, making SELF the fastest. All application speeds showed similar results in pre-intervention measurements of the mechanical properties of the tissues (P > 0.05). However, post hoc analysis revealed that a decrease was evident in SLOW compared to SELF in muscle tone in post-intervention measurements (P = 0.037). Also, we noted that comparison of pre- and post-intervention on FAST and SLOW showed a significant reduction in muscle tone (P = 0.002, P = 0.008). Slower foam rolling prior to training or competition may lead to a delay in the reaction time due to the reduction in tonus, that can increase the injury risks. Alternatively, the significant reduction in tonus may be useful in regulating the increased tonus after training and competition.

Briefly about Obstetric Anesthesia
Authors: Franjic Sinisa
Published: August 2024

In order for surgical procedures during pregnancy to be as successful and safe as possible, it is necessary to know anesthetic drugs, skills in the implementation of certain anesthetic procedures, but also a good understanding of the physiology of pain, pregnancy and childbirth. Physiological adaptations to pregnancy begin already in the first trimester and affect almost every organ system in a woman's body. Physiological adaptations include changes in the respiratory, cardiovascular, hematopoietic, gastrointestinal, urogenital and endocrine systems, so it is necessary to thoroughly consider the mentioned parameters before choosing a particular anesthetic technique.
The Concept of Mandala and the Politics of Paradiplomacy in Indonesia
Authors: Utomo Ario Bimo , Widjaya Salsa Febiola Gading
Published: August 2024

The study of International Relations has been increasingly paying more attention to the rise of non-state entities as new global actors. Consequently, this also brings the concept of paradiplomacy, or the diplomatic activities conducted by substate governments, to the forefront of discussion within the discipline. However, since paradiplomacy mainly stems from the tradition of federalism in the Western world, limited studies have provided more theoretical nuance through case studies in non-Western, unitary states. This article attempts to fill the knowledge gap by exploring the politics of paradiplomacy in Indonesia, a developing unitary state. This article argues that the concept of mandala, a Southeast Asian philosophy of governance, can be utilized to understand the politics of paradiplomacy in Indonesia. The authors contend that the Indonesian paradiplomatic culture primarily stems from the mandala concept, which has consistently pervaded Southeast Asian political culture and influenced Indonesia's paradiplomacy architecture. This concept emphasizes harmony between the center and periphery. In the bigger picture, this article rejects the notion of an ‘ideal’ paradiplomatic culture based upon Western practices and contends that non-Western states might have their own interpretations of local-central relations, which are worth noticing.

Published: August 2024

Experimental investigations have been carried out to modify the surface properties of Cotton fabrics using low temperature DC glow discharge nitrogen plasma. Plasma treatment is an eco-friendly, dry and clean process over wet chemical methods and does not suffer from any environmental and health concerns [1]. The important plasma parameters such as power and working pressure are kept constant with various treatment times (5, 15, 30, and 60 mins). The plasma-treated cotton fabrics are optimized by XRD, FTIR, and SEM. A comparative study has been done for the untreated and different treated fibers. Pure SiO2 is coated on untreated and nitrogen plasma treated cotton fabrics by sputtering method. The samples are coated for different sputtering times (10 and 30 min). Finally, Reduced Graphene Oxide (RGO) is coated on plasma treated SiO2 deposited fabrics. RGO is prepared by modified hummers methods [2]. Our results provide a way to develop a filter for water purification.

O hemiciclo
Authors: Martins Luiz Renato
Published: August 2024

A tela sobre o Juramento do Jeu de Paume é uma não pintura e uma forma-síntese da modernidade. Encomendada pela Assembleia (1790) ao pintor David, a tela celebraria o ato no qual os deputados do Terceiro Estado insurgiram-se contra uma decisão do rei e decidiram redigir uma Constituição. O projeto, porém, não se realizou, apesar de sua importância – “grande e sublime” –, e da inventividade do pintor, que logrou formular o ineditismo do tema de modo inovador, como mostrou o desenho apresentado no Salão de 1791. Seu fundamento político se esfacelara e o quadro perdera sua razão de ser, conforme anunciou David em setembro de 1792. Isso liquida a questão? Não. A não pintura, como negativo do desenho, é hoje inseparável deste. Duas faces de uma mesma moeda, ambas contam de uma promessa desenhada e de sua negação – de uma modernidade desdobrada em seu outro.

A tanulmány témájával kapcsolatos különböző paradigmák értelmezése és elemzése alapján – ami a tanulmány első részében található – megállapítottuk, hogy számos kérdést illetően eltérő nézetekkel lehet találkozni a mezőgazdasági fenntarthatóság alapelveit és eszközrendszerét illetően. Úgy ítéljük meg, hogy az agroökológiai szempontok érvényesítése jelenti – több szakíró véleménye alapján – a fő irányt, az egyik legjobb lehetséges megoldást a mezőgazdasági fenntarthatóság folyamatos biztosítása értekében. Ugyanakkor az is megállapítható, hogy számos kérdés vetődik fel – mint például a fenntarthatóság és versenyképesség összefüggései, a termelés jövedelmezőségének alakulása, a biztonságos élelmiszer-ellátással szembeni növekvő igény biztosított lesz-e az inputszegény, de a környezetet kímélő technológiai megoldások alkalmazása esetén? Ezekre nem igazán adnak választ a szakírók. A fenntarthatóság és versenyképesség együttes érvényesítésének keretrendszerét az új közös agrárpolitika (KAP) és annak kapcsolódó speciális célkitűzései – versenyképesség növelése, méltányos jövedelem, környezetvédelem, tájkép és biodiverzitás megőrzése stb. – adja. Az eszközrendszerében kiemelt szerepet kap az Farm to Fork (F2F, Termőföldtől az asztalig) stratégia, amelynek fő célja az uniós mezőgazdaság fenntartható élelmiszerrendszerré alakítása. Ennek elérését egyes inputok volumenének csökkentésében látja. Véleményünk szerint a tartás- és termesztéstechnológiák innovatív módszerei továbbra is szerepet kapnak, mivel a fenntarthatóság és versenyképesség egyensúlyi helyzete biztosításában kulcsszerepük van. Tanulmányunk e második részében a különböző megoldási módok gazdasági vetületeit elemezzük forrásmunkák alapján. A fenntarthatóság és versenyképesség összefüggéseinek gazdasági vetületeit a brojlercsirkére vonatkozóan saját modellszámítással számszerűsítettük. A kapott eredmények alapján megállapítható, hogy a fenntarthatóság és versenyképesség egyensúlyi helyzetére nem lehet általános érvényű ajánlásokat, megoldási módokat adni. Ez az egyensúlyi helyzet függvénye a vállalat termelési szerkezetének, amelyet viszont a termőhely mint térbeni egység a vidékgazdaságba, a vállalat intézményi környezetébe és a társadalmi-gazdasági intézményrendszerbe való beágyazottsága, továbbá a gazdálkodó vagy menedzsment szakmai felkészültsége és végül a fenntarthatósághoz való attitűdje határoz meg.

This study evaluated the effect of two commercially available probiotics (Bifidobacterium animalis BB-12®, Chr. Hansen, and Lacticaseibacillus rhamnosus + Lacticaseibacillus paracasei culture FreshQ®9, Chr. Hansen) on quality parameters of plain yogurts and the development of Aspergillus sp. and Escherichia coli inoculated in the products. Sensory evaluations were performed on the second day after the manufacture of yogurts, while microbiological analysis and pH measurements were carried out at 5-day intervals during 30 days of storage at 4°C. Yogurt containing FreshQ®9 had lower pH values and reduced fermentation time than control or BB-12® yogurts, also presenting higher sensory grades. Aspergillus sp. and E. coli counts decreased in all types of yogurts, although the probiotic cultures did not affect these microbial adulterants. Data indicate that L. rhamnosus in combination with L. paracasei improved the overall quality of yogurt. Further studies are needed to explore the potential bioprotective effect of the evaluated probiotics against other spoilage microorganisms in yogurt.

Harnessing the Power of AI for Climate Change Impact Assessment

Climate change impact assessment is critical for creating adequate climate change mitigation and adaptation policies and plans. Critical infrastructure systems (e.g., water and energy systems) are particularly at risk for climate change impacts. In fact, a better understanding of climate change impacts on the water and energy systems would facilitate the fulfillment of SDG2 (end hunger), SDG 6 (clean water and sanitation), SDG 7 (affordable and clean energy), SDG 11 (sustainable cities and communities), and SDG 13 (climate action), with many indirect benefits across many other areas. Nonetheless, conducting climate change impact assessment, particularly at the community-level, is not an easy task. Often, the impact assessment models require access to substantial computational resources to run the complex models, as well as the expertise to work with those models and interpret their results, which may not be possible for all communities. As such, there is a need to expand climate change impact assessment to include more accessible models that can handle high-resolution, local data that is of interest to communities. Here, we highlight how climate impact assessment studies can benefit from the power of artificial intelligence (AI). The report details the use of AI model to conduct a computationally efficient climate change impact assessment. This model is applied to a case study across the United States of America (U.S.) as an example to showcase the insights it generates in real-world applications. To demonstrate this process, the study will focus on the impacts on coupled water and electricity demand (e.g., the water-electricity demand nexus). To conduct the impact assessment, the report demonstrates two different means of collecting future climate data—Coupled Model Intercomparison Project 5 (CMIP5) Earth System Models (ESMs) and contemporary climate analogs. Our results show significant increases across the Midwestern U.S. when using ESM-derived data. Similar results were found through the climate analog-derived data, suggesting that the analogs can be used successfully as proxies for traditional ESM data in communities that might not have access to the larger CMIP suite of models. Understanding the impacts of climate change on critical infrastructure is important for building sustainable and equitable policies for climate change mitigation and adaptation. These infrastructure systems are often interconnected (e.g., the water-energy nexus) and managed by local entities. Thus, while climate change is a global problem requiring cooperation across countries and sectors, many solutions require local action. In this sense, the results presented here can be used to deepen our scientific understanding of climate change impacts on the water-energy nexus, as well as develop novel methodologies that integrate AI with traditional climate change impact assessment to better prepare local communities for the future.
What’s That Frog? Evaluating a Crowdsourced Approach to Species Identification From Audio Recordings

Citizen science is rapidly advancing as a field, engaging the public in scientific research and outcomes, while obtaining large quantities of data. Within the natural sciences, identification of organisms by citizen scientists is an important and increasing source of biodiversity records. However, to ensure the reliability and quality of citizen science data, including species identifications, various strategies have been employed. Crowdsourcing is commonly used to increase confidence in data quality, where results are an aggregate of multiple responses. Projects utilising crowdsourcing techniques have focused on image-based datasets, and are taxonomically biased towards large and charismatic taxa. We explored the utility of crowdsourcing species identification from audio files of calling frogs. We developed a series of audio analysis trials, inviting members of the public to identify frog species from audio recordings submitted to the FrogID project. By comparing the identifications made by citizen scientists with those made by experts in frog identification, we evaluated the suitability of using crowdsourcing to identify frog species calling in 20–60-second audio files. Citizen scientists identified frog species with 57% accuracy, although this varied depending on species, task complexity, and the individual volunteer. By aggregating responses, the accuracy of citizen scientist responses increased to up to 66% when we required a consensus of two volunteers from five responses. Our results indicate that crowdsourcing the identification of multiple frog species from audio recordings is challenging, requiring further exploration into the benefits of training volunteers, providing detailed feedback, and weighting volunteer responses according to individual skill.

Self-efficacy is a particular set of beliefs that determines a person’s ability to complete a plan of action (Bandura, 1977). It is a capability to produce desired results and judgements about one’s ability to do a certain things. Teachers’ sense of efficacy refers to their determination and belief in their ability to accomplish important teaching tasks. Sense of efficacy play an important role in improving teachers’ teaching and ultimately student outcomes. To find out the status of sense of efficacy of the teacher educators, Teachers Sense of Efficacy Scale (TSES) (Tschannen-Moran & Woolfolk Hoy, 2001) was administered on a random sample of 305 teacher educators of self-financed B.Ed. colleges of South 24 Parganas. It was reflected from the result that male teacher educators expressed their very high sense of efficacy and female teacher educators exposed high sense of efficacy; and male teacher educators manifested their (statistically) significantly higher sense of efficacy than the female teacher educators. It may be concluded that the teacher educators, irrespective of gender have very high sense of efficacy.

To explore the influence of self-concept and academic life satisfaction on the development of achievement motivation among adolescents in school, this research employed a descriptive survey approach with a correlational research design. A sample of 1027 Bengali-speaking adolescents, aged 14-16 and enrolled in classes IX and X in the South 24 Parganas District, West Bengal, participated in the study. The Self-Concept Inventory (Shah, 1986), Multidimensional Student’s Life Satisfaction Scale (Huebner et al., 1998), and Deo-Mohan Achievement Motivation Scale (Deo & Mohan, 1985) were administered. The correlation analysis revealed a strong positive connection between self-concept, academic life satisfaction, and achievement motivation in adolescents. The results from the multiple regression analysis suggested that the achievement motivation of school-going adolescents was shaped by several factors, including family life satisfaction, school life satisfaction, friend life satisfaction, cognitive self-concept, study-related self-concept, self-confidence, self-concept related to personality traits, and political self-concept. The study’s findings revealed significant associations between academic achievement motivation and both academic life satisfaction and self-concept.
