Abstract. Traditional animal dung fuel use is a prominent source of brown carbon (BrC) in the Tibetan Plateau (TPL) region. Changes in burning conditions, fuel types, and uses of dung fuels in Plateau areas can lead to considerable uncertainties about molecular absorption properties and their radiative forcing influence on BrC. Here, the constituents of BrC’s chromophoric molecules emitted from residential heating and cooking scenarios using dung fuels were proposed using ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry in the TPL region, China. Our results show that dung fuels in this study can release abundant BrC emissions with substantial high BrC absorption when compared with those observed in bitumite. Particularly, the linkage between BrC molecules and their absorption properties was quantified by partial least squares regression. Among detected BrC’s molecular groups, above 70 % of N-containing compounds (CHON and CHONS) with low-oxygen-containing and unsaturated aromatic bonds and 20.9–27.5 % of CHO compounds measured from the dung combustion samples were lies in the potential BrC chromophores regions. Further, a significantly enhanced contribution of molecular absorption coefficient (Mbabs) to total Mbabs (up to 99.7 %) was observed in the presence of both CHO and CHON (N2+N4) with distinctive characteristics of long carbon chains and high levels of unsaturation. Interestingly, the identified CHONS markers were highly oxygenated with abundant unsaturated double-bonds and high Mbabs, but were rarely produced under insufficient oxygen conditions at the high-altitude plateau. Meanwhile, the incomplete combustion of dung produced high values of integrated simple forcing efficiency and thus destroyed the radiation balance over the TPL region.

Abstract. The atmospheric oxidation of dimethyl sulfide (DMS)
represents a major natural source of atmospheric sulfate aerosols. However,
there remain large uncertainties in our understanding of the underlying
chemistry that governs the product distribution and sulfate yield from DMS
oxidation. Here, chamber experiments were conducted to simulate gas-phase
OH-initiated oxidation of DMS under a range of reaction conditions. Most
importantly, the bimolecular lifetime (τbi) of the peroxy radical
CH3SCH2OO was varied over several orders of magnitude, enabling
the examination of the role of peroxy radical isomerization reactions on
product formation. An array of analytical instruments was used to measure
nearly all sulfur-containing species in the reaction mixture, and results
were compared with a near-explicit chemical mechanism. When relative
humidity was low, “sulfur closure” was achieved under both high-NO (τbi<0.1 s) and low-NO (τbi>10 s)
conditions, though product distributions were substantially different in the
two cases. Under high-NO conditions, approximately half the product sulfur
was in the particle phase, as methane sulfonic acid (MSA) and sulfate, with
most of the remainder as SO2 (which in the atmosphere would eventually
oxidize to sulfate or be lost to deposition). Under low-NO conditions,
hydroperoxymethyl thioformate (HPMTF, HOOCH2SCHO), formed from
CH3SCH2OO isomerization, dominates the sulfur budget over the
course of the experiment, suppressing or delaying the formation of SO2
and particulate matter. The isomerization rate constant of
CH3SCH2OO at 295 K is found to be 0.13±0.03 s−1, in
broad agreement with other recent laboratory measurements. The rate
constants for the OH oxidation of key first-generation oxidation products
(HPMTF and methyl thioformate, MTF) were also determined (kOH+HPMTF=2.1×10-11 cm3 molec.−1 s−1, kOH+MTF=1.35×10-11 cm3 molec.−1 s−1). Product measurements
agree reasonably well with mechanistic predictions in terms of total sulfur
distribution and concentrations of most individual species, though the
mechanism overpredicts sulfate and underpredicts MSA under high-NO
conditions. Lastly, results from high-relative-humidity conditions suggest efficient
heterogenous loss of at least some gas-phase products.

Abstract. The temperature of the earth is one of the most important climate parameters. Proxy records of past climate changes, in particular temperature, are a fundamental tool for exploring internal climate processes and natural climate forcings. Despite the excellent information provided by ice core records in Antarctica, the temperature variability of the past 2000 years is difficult to evaluate from the low accumulation sites in the Antarctic continent interior. Here we present the results from the Aurora Basin North (ABN) ice core (71° S, 111° E, 2690 m a.s.l.) in the lower part of the East Antarctic plateau where accumulation is substantially higher than other ice core drilling sites on the plateau, and provide unprecedented insight in East Antarctic past temperature variability. We reconstructed the temperature of the last 2000 years using two independent methods: the widely used water stable isotopes (δ18O), and by inverse modelling of borehole temperature and past temperature gradients estimated from the inert gas stable isotopes (δ40Ar and δ15N). This second reconstruction is based on three independent measurement types: borehole temperature, firn thickness, and firn temperature gradient. The δ18O temperature reconstruction supports stable temperature conditions within 1 °C over the past 2000 years, in agreement with other ice core δ18O records in the region. However, the gas and borehole temperature reconstruction suggest that surface conditions 2 °C cooler than average prevailed in the 1000–1400 CE period, and support a 20th century warming of 1 °C. These changes are remarkably consistent with reconstructed Southern Annular Mode (SAM) variability, as it shows colder temperatures during the positive phase of the SAM in the beginning of the last millennium, with rapidly increasing temperature as the SAM changes to the negative phase. The transition to a negative SAM phase after 1400 CE is however not accompanied by a warming in West Antarctica, which suggests an influence of Pacific South American modes, inducing a cooling in West Antarctica while ABN is warming after this time. A precipitation hiatus during cold periods could explain why water isotope temperature reconstruction underestimates the temperature changes. Both reconstructions arguably record climate in their own way, with a focus on atmospheric and hydrologic cycles for water isotopes, as opposed to surface temperature for gases isotopes and borehole. This study demonstrates the importance of using a variety of sources for comprehensive paleoclimate reconstructions.
Evaluating the Impact of Enhanced Horizontal Resolution over the Antarctic Domain Using a Variable-Resolution Earth Systems Model

Published: December 2022

Abstract. Earth System Models are essential tools for understanding the impacts of a warming world, particularly on the contribution of polar ice sheets to sea level change. However, current models lack full coupling of the ice sheets to the ocean, and are typically run at a coarse resolution (1 degree grid spacing or coarser) to save on computational expense. Coarse spatial resolution is particularly a problem over Antarctica, where sub-gridscale orography is well-known to influence precipitation fields. This resolution limitation has been partially addressed by regional climate models (RCMs), which must be forced at their lateral and ocean surface boundaries by (usually coarser) global atmospheric datasets, However, RCMs fail to capture the coupling between the regional domain and the global climate system. Conversely, running high spatial resolution models globally is computationally expensive, and can produce vast amounts of data. Alternatively, variable-resolution, nested grids are a promising way forward, as they can retain the benefits of high resolution over a specified domain without the computational costs of running at a high resolution globally. Here we evaluate a historical simulation of the Community Earth System Model, version 2, (CESM2) implementing the spectral element (SE) numerical dynamical core with an enhanced-horizontal-resolution (0.25°) grid over the Antarctic Ice Sheet and the surrounding Southern Ocean; the rest of the global domain is on the standard 1° grid. We compare it to a 1° model run of CESM2 using the standard finite-volume dynamical core with identical physics and forcing, including prescribed SSTs and sea ice concentrations from observations. Our evaluation indicates both improvements and degradations in VR-CESM2 performance relative to the 1° CESM2. Surface mass balance estimates are slightly higher, but within one standard deviation of the ensemble mean, except for over the Antarctic Peninsula, which is impacted strongly by better-articulated surface topography. Temperature and wind estimates are improved over both the near-surface and aloft, although the overall correction of a cold bias (within the 1° CESM2 runs) has resulted in temperatures which are too high over the interior of the ice sheet. The major degradations include the enhancement of surface melt as well as excessive liquid cloud water over the ocean, with resultant impacts on the radiation balance. Despite these changes, VR-CESM2 is a valuable tool for the analysis of future estimates of precipitation and surface mass balance, and thus constraining estimates of sea level rise.
Water Productivity of Phoenix Metropolitan Area Cities
Authors: Ruddell Benjamin , Rushforth Richard , Hope Diane
Published: December 2022

Abstract. Water productivity (or efficiency) data informs water policy, zoning and planning along with water allocation decisions under water scarcity pressure. This paper demonstrates that different water productivity metrics lead to different conclusions about who is using water more effectively. In addition to supporting the population's drinking and sanitation needs, water generates many other public and private social, environmental, and economic values. For the group of municipalities comprising the Phoenix Metropolitan Area we compare several water productivity metrics by calculating the Water Value Intensity (WVI) of potable water delivered by the municipality to its residential and non-residential customers. Core cities with more industrial water uses are less productive by the conventional efficiency measure of water used per capita, but core cities generate more tax revenues, business revenues, and payroll revenues per unit of water delivered, achieving a higher water productivity by these measures. We argue that policymakers should consider a more diverse set of socio-economic water productivity measures to ensure that a broader set of values are represented in water allocation policies.
Producing SWOT measurements with a multiscale data assimilation system during the prelaunch field campaign
Authors: Li Zhijin , Archer Matthew R. , Wang Jinbo , Fu Lee-Lueng
Published: December 2022

Abstract. A data assimilation system for a high-resolution model has been developed to address the opportunities and challenges posed by the upcoming Surface Water and Ocean Topography (SWOT) satellite mission. This developed system is based on a three-dimensional variational data assimilation scheme (3DVAR), which is computationally highly efficient and thus can be applied to a very high-resolution model. A crucial consideration of the system is to use a multiscale data assimilation approach (MSDA) to first assimilate routinely available observations, including conventional satellite altimetry, sea surface temperature (SST) and salinity (SSS), and temperature/salinity vertical profiles, to constrain large scales and large mesoscales. High-resolution (dense) observations and future SWOT measurements can then be effectively and seamlessly assimilated to constrain the smaller scales. The 3DVAR is extended to assimilate observations over a time interval, which specifically enhances the efficacy of the assimilation of satellite along-track altimetry observations, which are limited by large repeat time intervals. Using this system, a reanalysis dataset was produced for the SWOT pre-launch field campaign that took place in the California Current System from September through December, 2019. An evaluation of this system with assimilated and withheld data demonstrates its ability to effectively utilize both routine and campaign observations to produce sea surface heights with the accuracy close to that required by SWOT. These results suggest a promising avenue for data assimilation development in the SWOT altimetry era, which will need the capability of jointly assimilating existing routine observations with SWOT measurements to resolve small-scale ocean processes.
WaterBench-Iowa: a large-scale benchmark dataset for data-driven streamflow forecasting
Authors: Demir Ibrahim , Xiang Zhongrun , Demiray Bekir , Sit Muhammed
Published: December 2022

Abstract. This study proposes a comprehensive benchmark dataset for
streamflow forecasting, WaterBench-Iowa, that follows FAIR (findability, accessibility, interoperability, and reuse) data principles
and is prepared with a focus on convenience for utilizing in data-driven
and machine learning studies, and provides benchmark performance for
state of art deep learning architectures on the dataset for comparative
analysis. By aggregating the datasets of streamflow, precipitation,
watershed area, slope, soil types, and evapotranspiration from federal
agencies and state organizations (i.e., NASA, NOAA, USGS, and Iowa Flood
Center), we provided the WaterBench-Iowa for hourly streamflow forecast
studies. This dataset has a high temporal and spatial resolution with rich
metadata and relational information, which can be used for a variety of deep learning and machine learning research. We defined a sample benchmark task
of predicting the hourly streamflow for the next 5 d for future
comparative studies, and provided benchmark results on this task with sample
linear regression and deep learning models, including long short-term memory
(LSTM), gated recurrent units (GRU), and sequence-to-sequence (S2S). Our
benchmark model results show a median Nash-Sutcliffe efficiency (NSE) of 0.74 and a median Kling-Gupta efficiency (KGE) of 0.79
among 125 watersheds for the 120 h ahead streamflow prediction task.
WaterBench-Iowa makes up for the lack of unified benchmarks in earth science research and can be accessed at Zenodo https://doi.org/10.5281/zenodo.7087806 (Demir et al., 2022a).

Published: December 2022

Abstract. Although evidence of the hydrological response of watersheds to climate change is abundant, reliable assessments of water yield (WY) over mountainous regions, such as the Upper Brahmaputra River (UBR) basin, remain unclear. Here, we examine long-term WY changes during 1982–2013 in the UBR basin, based on multi-station runoff observations. We find that there are significant shifts in hydrological regimes in the late 1990s; WY increases in the range of ∼10 % to ∼80 %, while the directions reverse from increasing to decreasing. Additionally, the double mass curve (DMC) technique is used to assess the effects of climate, vegetation, and cryosphere on WY changes. Results show that cryosphere and climate together contribute to over 80 % of the increase in WY across the entire UBR basin, while the role of vegetation is negligible. The combined effects, however, are either offsetting or additive, thus leading to slight or substantial magnitude increases, respectively. The downward WY trend has primarily been regulated by decreased precipitation in recent years. However, we find that meltwater may alleviate the resulting water shortage in some basins. Therefore, the combined effects of climate and cryosphere on WY should be considered in future water resources management over mountainous basins, particularly involving co-benefits between upstream and downstream regions.
Estimation of stream water components and residence time in a permafrost catchment in the central Tibetan Plateau using long-term water stable isotopic data
Authors: Wang Shaoyong , He Xiaobo , Kang Shichang , Fu Hui , Hong Xiaofeng
Published: December 2022

Abstract. Global warming has significantly impacted the
hydrological processes and ecological environment in permafrost regions.
Mean residence time (MRT) is a fundamental catchment descriptor that
provides hydrological information regarding storage, flow pathways, and water
source within a particular catchment. However, water stable isotopes and MRT
have rarely been investigated due to limited data collection in the
high-altitude permafrost regions. This study uses the long-term stable
isotopic observations to identify runoff components and applied the
sine-wave exponential model to estimate water MRT in a high-altitude
permafrost catchment (5300 m a.s.l.) in the central Tibetan Plateau (TP).
We found that the isotope composition in precipitation, stream, and
supra-permafrost water exhibited obvious seasonal variability. The freeze–thaw
process of the permafrost active layer and direct input of precipitation
significantly modified the stable isotope compositions in supra-permafrost
and stream water. The hydrograph separation revealed that precipitation and
supra-permafrost water accounted for 35 ± 2 % and 65 ± 2 %
of the total discharge of stream water, respectively. MRT for stream and
supra-permafrost water was estimated at 100 and 255 d, respectively. Such
shorter MRTs of supra-permafrost and stream water (compared to the
non-permafrost catchments) might reflect the unique characteristics of
the hydrological process in permafrost catchments. Moreover, the MRT of
supra-permafrost water was more sensitive to environmental change than that
of stream water. Climate and vegetation factors affected the MRT of stream
and supra-permafrost water mainly by changing the thickness of the permafrost
active layer. Our results suggest that climate warming might retard the rate
of water cycle in permafrost regions. Overall, our study expands our
understanding of hydrological processes in high-altitude permafrost
catchments under global warming.
The surface energy balance during foehn events at Joyce Glacier, McMurdo Dry Valleys, Antarctica

Published: December 2022

Abstract. The McMurdo Dry Valleys (MDV) are a polar desert, where glacial melt is the main source of water to streams and the ecosystem. Summer air temperatures are typically close to zero, and therefore foehn events can have a large impact on the meltwater production. A 14-month record of automatic weather station (AWS) data on Joyce Glacier is used to force a 1D surface energy balance model to study the impact of foehn events on the energy balance. AWS data and output of the Antarctic Mesoscale Prediction System (AMPS) on a 1.7 km grid are used to detect foehn events at the AWS site. Foehn events at Joyce Glacier occur under the presence of cyclones over the Ross Sea. The location of Joyce Glacier on the leeward side of the Royal Society Range during these synoptic events causes foehn warming through isentropic drawdown. This mechanism differs from the foehn warming through gap flow that was earlier found for other regions in the MDV and highlights the complex interaction of synoptic flow with local topography of the MDV. Shortwave radiation is the primary control on melt at Joyce Glacier, and melt often occurs with subzero air temperatures. During foehn events, melt rates are enhanced, contributing to 23 % of the total annual melt. Foehn winds cause a switch from a diurnal stability regime in the atmospheric surface layer to a continuous energy input from sensible heat flux throughout the day. The sensible heating during foehn, through an increase in turbulent mixing resulting from gustier and warmer wind conditions, is largely compensated for by extra heat losses through sublimation. Melt rates are enhanced through an additional energy surplus from a reduced albedo during foehn.

Published: December 2022

Abstract. Snow conditions in the northern hemisphere are rapidly changing, and information on snow depth is critical for decision-making and other societal needs. Unmanned aircraft systems (UASs) can offer data resolutions of a few centimeters at a catchment-scale, and thus provide a low-cost solution to bridge the gap between sparse manual probing and low-resolution satellite data. In this study, we present a series of snow depth measurements using different UAS platforms throughout the winter in the Finnish subarctic site Pallas, which has a heterogeneous landscape. We discuss the different platforms, the methods utilized, difficulties working in the harsh northern environment, and the results and their accuracy compared to in situ measurements. Generally, all UASs produced spatially representative estimates of snow depth in open areas after reliable georeferencing by using the Structure from Motion (SfM) photogrammetry technique. However, significant differences were observed in the accuracies produced by the different UASs compared to manual snow depth measurements, with overall RMSEs varying between 13.0 to 25.2 cm, depending on the UAS. Additionally, a reduction in accuracy was observed when moving from an open mire area to forest covered areas. We demonstrate the potential of low-cost UASs to efficiently map snow surface conditions, and we give some recommendations on UAS platform selection and operation in a harsh subarctic environment with variable canopy cover.
Design and Fabrication of an Instrument for Splitted Jute Fiber Length Measurement

Published: December 2022

Fibers are the main raw materials in the textile industry. Now-a-days various types of fibers are available around the world, but all fibers are not textile fibers. Because for being textile fibers, the fibers must have some particular physical and chemical properties. The length of natural fiber plays an important role both in the spinning process and product quality. In this work, it is highlighted about a long staple natural fiber which is called jute fiber. In the 19th century, jute fiber was called the *Golden Fiber* of Bangladesh. After that this fiber lost its name and fame for the cause of our negligence and lack of knowledge. It is very difficult to know about jute because a few people were working on it. Though it’s a long fiber but there are some problems with its fixed length because this fiber consists of a large number of ultimate cells whose length is 1.5 to 4 millimeters, and these cells are attached by lignin which is known as natural cement. A long fiber which is 5 to 10 feet forms after attaching these ultimate cells. During the retting period some of the lignin layers break down and long fiber length of fibers becomes shorter. Another important thing is these fibers have a mesh structure for this reason it’s difficult to identify the actual length of the fibers. That’s why fibers obtained after retting are passed through jute carding machines. The main function of the jute carding machine is to split up and break down the mesh structure. After carding, it’s quite easy to measure the length of splitted jute fibers. There are not any suit-able machines for measuring the length of jute fibers. Previously people use the scale for measuring the jute fibers' length manually, through this it is so difficult to measure the length of the long fibers accurately. Here an instrument has been designed with Arduino UNO, Ultrasonic distance sensor, Image-j software, C-programming and fabricated for measuring the fibers' length easily and accurately as well as this instrument can measure the number of fibers in that particular length. By using this instrument  anyone can easily measure the length of the fibers and the number of fibers within a short possible time efficiently.

Authors: Kwok Wan Yu , So Billy Chun Lung , Ng heung Mei Shamay
Published: December 2022

This systematic review is aimed to provide an up-to-date summary and review on the use of surface electromyography (sEMG) in evaluating front crawl (FC) swim performance. Several online databases were searched by different combinations of selected keywords, in total 1956 articles were retrieved, and each article was assessed by a 10-item quality checklist. 16 articles were eligible to be included in this study, and most of the articles were evaluating the muscle activity about the swimming phases and focused on assessing the upper limbs muscles, only few studies have assessed the performance in starts and turns phases. Insufficient information about these two phases despite the critical contribution on final swimming time. Also, with the contribution roles of legs and trunk muscles in swimming performance, more research should be conducted to explore the overall muscle activation pattern and their roles on swimming performance. Moreover, more detailed description in participants’ characteristics and more investigations of bilateral muscle activity and the asymmetrical effects on relevant biomechanical performance are recommended. Lastly, with increasing attention about the effects of muscles co-activation on swimming performance, more in-depth investigations on this topic are also highly recommended, for evaluating its influence on swimmers.

Published: December 2022

La región del Noroeste Argentino presenta un desarrollo de la actividad olivícola con excelentes resultados productivos destinados a la Industria aceitera. Sin embargo, esta evolución productiva trajo aparejada la necesidad de tratar aquellos residuos sólidos producto de esta industria alimenticia. Es por ello que la Universidad Nacional de La Rioja se encuentra trabajando en líneas prioritarias sobre Control y Protección del Medio Ambiente dentro de un modelo de desarrollo sustentable con el objetivo de disminuir estos desechos industriales que terminan en vertederos o en rellenos sanitarios. En este sentido la presente investigación busca reciclarlos en placas de aglomerado para luego determinar y analizar sus propiedades físicas y mecánicas. Las probetas ensayadas resultaron tener un buen comportamiento ante procesos de corte. La densidad del aglomerado presentó un perfil de alta densidad, siendo beneficioso, ya que los materiales de baja densidad son más susceptibles de sufrir los rigores de la humedad. El ensayo de humedad mostró un índice del adecuado fraguado y el de hinchamiento indicó resistencia a la influencia del agua. Con respecto a la resistencia a la flexión, los resultados indicaron que la deformación por carga máxima y la deformación por flexión a la rotura son mayores en el caso del aglomerado de orujo, siendo la carga máxima de flexión el factor más desfavorable de las probetas a base de orujo.

Turismo de naturaleza en España. Nuevas realidades, nuevos modelos de turismo sostenible
Authors: Moreno Duque Desireé
Published: December 2022

El turismo en España en uno de los motores del país con un aporte al PIB en el año 2019 12,4% (INE,2020), un porcentaje que ha ido aumentando cada año, hasta la llegada de la Covid- 19, haciendo que España se situase como un destino preferencial para los turistas. España siempre ha sido considerado un buen destino para disfrutar las vacaciones estivales, debido a su climatología y los servicios que posee, además de las infraestructuras que facilitan estos accesos. Este turismo se da sobre todo en la costa mediterránea y en las Islas, debido a que la motivación de “sol y playa” sigue siendo uno de los motivos principales que condicionan a los turistas para visitar nuestro país. Si bien, España es mucho más que eso, tiene otros valores y recursos potenciales, en zonas de interior, aún pendientes de emerger, como es el caso del turismo de naturaleza, característico de las zonas rurales, que, con las medidas necesarias, se puede potenciar para que suponga un incremento de la llegada de visitantes a estos nuevos destinos, lo cual podría condicionar algunos aspectos positivos como el crecimiento de la economía local y evitar la despoblación de las zonas rurales. El turismo de naturaleza es un valor añadido para el turismo en España que, con una buena gestión y organización de los medios puede convertirse en un punto clave del turismo del país. Por todo lo expuesto, en el presente estudio se aborda el análisis del conjunto de recursos naturales con los que cuenta España, presentándolos como lugares idóneos para la realización de actividades turísticas en dichos entornos, de manera que, con una buena gestión y promoción de los mismos se puede incrementar el turismo en las zonas que dispongan de las características necesarias para promover un turismo de naturaleza, y, sostenible.
Bienestar subjetivo infantil: lecciones aprendidas considerando a niños y niñas como informantes clave
Authors: Casas Aznar Ferran
Published: December 2022

Este artículo analiza algunos de los resultados que parecen más destacables de la investigación científica sobre bienestar subjetivo (BS) en la infancia y la adolescencia las últimas dos décadas, cuando se han utilizado muestras representativas a nivel poblacional. Se ha puesto énfasis en los resultados más inesperados y en los hallazgos que no hubieran sido posibles sin dar credibilidad a los niños y niñas como informantes clave de sus propias vidas, así como en la comparabilidad intercultural. Se repasa someramente el contexto histórico del estudio del BS en general, destacando el enorme retraso con que ha evolucionado el del BS infantil en comparación con el de los adultos. El trasfondo de esta situación se señala que puede estar en la escasa relevancia que se da a menudo a la población infantil en el contexto político, y, en consecuencia, al poco interés para que haya disponibilidad de indicadores sociales subjetivos sobre la situación de la infancia a nivel poblacional. Por ello, se insiste en la importancia y utilidad de este tipo de indicadores para la toma de decisiones políticas. También se revisa el tipo de datos que ya están disponibles en algunos organismos internacionales y en otros contextos, para ilustrar sus potencialidades, el lento pero progresivo aumento de su producción y análisis, y sus limitaciones actuales, inseparables de los retos pendientes de afrontar en el futuro próximo por parte de los investigadores, los políticos y la sociedad en este campo. Se concluye con una reflexión sobre lo importante que es para niños, niñas y adolescentes sentirse escuchados incluso por los investigadores científicos, y constatar que no solo nos interesan sus problemas, sino también los aspectos positivos que impregnan sus vidas, como su satisfacción vital y su bienestar subjetivo.

تهتم هذه الدراسة بتتبع طريقة اشتغال النغم / النغمة في ألسن مختلفة، سواء في مستوى ربطها بالكلمات أو الجمل أو التراكيب، وذلك من أجل رصد مدى اختلاف الألسن أو تشابهها في توظيف النغم، وكيف أنه يشكل الجرس الموسيقي الخفي للألسن، مضيفا لغة على لغة، تحمل العديد من المعاني التي قد تتشابه بين الألسن أو تختلف فيما بينها، بل أن النغم في نفس اللسان وتحديدا في نفس الكلمة يعطي عدة معان مختلفة على حسب حال الباث (المتكلم) أو حال المتلقي (المستقبل) أو على حسب الموقف. ولتحقيق ذلك اعتمدت المنهج الاستقرائي للتأكد من صحة الفرضية، والتي تعتبر نقطة انطلاق للمنهج الاستنتاجي القائم على اختبار الفرضية الموجودة لتحليلها وفهم تفاصيلها، أي من الكل إلى الجزء لفهم الفرضية بشكل معمق، منطلقة من افتراض مفاده أنّ الألسن تتفق في وجود نغمة غير مباشرة في الكلمات والجمل والتراكيب تعبر فيها عدة معاني بين الباث (المتكلم) والمتلقي (المستقبل). ولاختبار هذه الفرضية استعنت بعينة استقيتها من موقعwals.info، ومراجع أخرى في علم اللسانيات تحديدا الفونولوجيا، فهناك ألسن تتميز بالنغمة العميقة، وأخرى بالنغمة المتوسطة أو السطحية وأخرى بالمعقدة، وهذا ما يهدف له البحث وهو تحديد بعض الألسن النغمية والغير نغمية، التي تنعكس على هوية الألسن المتأثرة بالبيئة والمجتمع المحيط وهذا ما يجعل للبحث أهمية تتمحور حول اكتشاف وتوضيح اللغة الخفية في بعض الألسن التي لا تقل أهمية عن مخارج الأصوات وصفاتها ألا وهي النغم الذي يغير المبنى والمعنى معا، ويختلف من لسان لآخر، وهذا ما جعل علماء اللسانيات يختلفون في نظرياتهم حول علاقة النغم باللسانيات تاركة الباب مفتوحا لدراسات مستقبلية خاصة في مجال الفنولوجيا والفونوتيقا تعطي نتائج أكثر دقة.

LOCAL ECO-ACTIVIST’S PERSPECTIVES ON ENVIRONMENTAL AWARENESS ISSUES IN KAZAKHSTAN
Authors:   KIMEP University, Kumar Yernazar
Published: December 2022

Environmental issues in Kazakhstan are one of the most undermined research areas in Kazakhstan, particularly if we are speaking about aspects on environmental awareness. This study asked Kazakhstani eco-activists to provide their expert-rich responses to eleven open-ended questions related to environmental awareness aspects in Kazakhstan, which were divided into five sections, namely 1) degree of the environmental problem in the country; 2) reasons for the existence of the environmental problem; 3) role of the government in environmental awareness aspects; 4) the role of civil society in environmental awareness matters; and 5) solutions and prospects. For that, ten eco-activists have participated in our study, who were selected from the social media website ‘Linkedin’ via a convenience sampling method. As a data analysis, a content analysis approach was used. Our results have indicated that environmental awareness level has improved since 1990’s and numerous factors ranging from low levels of ecological literacy and environmental activism were mentioned as reasons for existence of low level of environmental awareness. By now, there are practically no empirical data on how eco-activists view, comprehend and assess environmental awareness issues in Kazakhstan. Such primary data could help share valuable insight on important policy and research aspects, namely concerning ineffectiveness of government-initiated actions, role of civil society in pro-environmental projects, studying level of awareness for government-initiated environmental programs, or policy proposals in tackling low environmental awareness levels. Thus, our research could be both valuable for researchers in filling the research gap and for practitioners in proposing viable policy alternatives to address environmental awareness issues. Despite the study’s research limitations concerning lack of international eco-activist’s focus, social-desirability-response bias and low sample size representativeness, this study recommends conducting expert interviews with NGOs (e.g. UNECE or CARECECO), reintegrate environmental concern and activism aspects as well as focus on policy solutions.
