Authors: Gur Tamer , Balta Nuri , Dauletkulova Aigul , Assanbayeva Gulzhaukhar , Fernández-Cézar Raquel
Published: October 2023

Emotions such as anxiety, fear, and frustration can interfere with cognitive processing and hinder our ability to learn and perform well on tasks. Mathematics is a school subject that could generate various emotions in students. This study examined mathematics achievement emotions of students across gender, grade level, and academic performance. Data was collected from 246 students using a questionnaire measuring seven emotions: enjoyment, pride, anger, anxiety, shame, hopelessness, and boredom. Results indicated that except for females’ higher pride, we did not find differences between males' and females’ emotions. Ninth-grade students demonstrated higher anxiety and shame than grade seven and eight students. Finally, students’ mathematics exam grades are weakly correlated with all seven measured emotions. Our findings add to the literature by presenting that emotions are contextual. Except for pride, the results clearly indicated that math emotions in our sample are gender irrelevant and further imply that the socio-cultural context of Kazakhstan supports females to compete with their male friends.

Published: October 2023

An onto-semiotic analysis of the mathematical connections established by one in-service mathematics teachers and university students when solving a problem about launching a projectile using the derivative was carried out. Theoretically, this research was based on the articulation between the Extended Theory of Mathematical Connections and the Onto-semiotic Approach. The methodology was qualitative-descriptive where data was collected through interviews based on a task. Subsequently, following the joint analysis method of both theories, the mathematical activity of the participants when they solved the task was analyzed. The results show that, teacher and students established a system of connections of feature type, different representations, meanings, part-whole, procedural and implications in terms of practices, processes, objects, and semiotic functions that relate them. However, some students presented difficulties caused by some incorrect mathematical connection such as stating that the maximum height of the projectile is the time obtained with the critical number, errors in performing arithmetic calculations when evaluating the function, graphically representing the quadratic function as a straight line and use the general formula in an inappropriate way that prevents the procedural connection from being made.

One of the Education for Sustainable Development Goals is to provide equitable and inclusive access to quality education for all. However, some children with special needs, particularly slow learners, have yet to be able to enjoy inclusive and high-quality learning services. This research aims to enhance slow learners' competence by implementing the Realistic Mathematics Education Approach. It is descriptive qualitative research, with data collection techniques including focus group discussion, interview, and learning observation. The analysis involved comparing the principles of Realistic Mathematics Education in theory with those applied by teachers, as well as the learning approach used by teachers with those required by slow learners. The findings indicate that while some teachers have implemented learning based on the principles of Realistic Mathematics Education for all students, there needs to be more focus on interventions specifically tailored to the needs of slow learners. Furthermore, teachers still need to fully understand the services required by slow learners based on their unique characteristics. The implementation of Realistic Mathematics Education to meet the learning needs of slow learners in mathematics has primarily focused on activity and interactivity principles without emphasis on the understanding of concepts to enhance their competence.

Published: October 2023

To identify the level of education of schoolchildren in different countries of the world, the OECD conducts international studies in the field of education. Comparative results of these studies make it possible to determine the effectiveness of national educational systems contributing to adapting programs for modernization and reform of educational systems. This study aims to develop mathematical literacy among 15-year-old students of the Republic of Kazakhstan by developing the basic skills of the 21st century in solving practice-oriented problems. An experimental study was conducted to determine teachers' attitudes toward the formation of mathematical literacy among schoolchildren. The study involved 32 teachers. The Analysis of the results of the survey revealed that the majority of teachers had a negative attitude towards the formation of mathematical literacy among schoolchildren, substantiating their points of view by the fact that the formation and development of mathematical knowledge and skills by itself contributed to the development of skills in the 21st century. Only 11% of teachers could accurately indicate those tasks, out of the seven tasks presented for consideration, in the solution of which schoolchildren had shown critical, systemic thinking. An analysis of geometry textbooks used in schools of the Republic of Kazakhstan showed that out of the total number of educational tasks studied in geometry lessons, the share of practice-oriented tasks comprised less than 3%. Based on the results of the experimental study, it is concluded that it is necessary to develop appropriate methodological approaches that contribute to the formation of mathematical literacy among schoolchildren using the learning tasks of the school geometry course.

Published: October 2023

The study material on circle areas is contextually oriented and aids students in comprehending their surrounding environment. Higher-order thinking skills are imperative for the success of circular learning, as they help students grasp concepts holistically and solve concept problems. "What-if" questions can enhance students' higher-order thinking skills through problem-solving activities, fostering critical and creative thinking. However, applying "what-if" questions is limited to serving as problem-posing triggers, resulting in minimal variation in the material. Therefore, this study aims to design a learning trajectory for the area of circles based on "what-if" questions to enhance students' higher-order thinking skills. This research also addresses the gap by utilizing "what-if" questions to construct and evaluate circle area learning activities. We employed design research as the research method, conducted in three stages: preliminary design, experimental design, and retrospective analysis. The results demonstrated that the designed learning trajectory enhanced higher-order thinking skills in various aspects. Students exhibited critical thinking and profound analysis when working on worksheets and addressing the provided problems. Moreover, students showcased creative and divergent thinking abilities, enabling them to generate alternative problem solutions. Furthermore, optimizing technology usage and emphasizing reasoning in learning should be augmented to enhance student motivation and foster innovative learning.

Published: October 2023

This paper aims to describe the development process of the Observation Protocol for Teaching Activities in Mathematics (POAEM) and to report the findings from the qualitative and statistical analyses used to provide evidence of validity and reliability of the information collected with the first version of the POAEM. As part of this development process, 20 teachers from Mexican primary schools were videotaped twice while teaching mathematics. The study assessed the reliability of the POAEM rubrics. Results showed that the dimensional structure of the instrument can be grouped in one factor. A generalizability study provided information on the different sources of error in the measurement, showing that the dimensions accounted for 78% of the variance. This study provides an exemplar of the design and validation of an instrument that can help other researchers develop their own instruments and data collection to generate evidence of validity and reliability in different sociocultural contexts.
American Farmers’ Attitudes toward China and the U.S.–China Trade Dispute: A Mediated Relationship
Authors: Han Guang , Rodriguez Lulu , Qu Shuyang
Published: October 2023

The trade dispute between the U.S. and China significantly cut agricultural product sales to a major foreign market and drastically hurt Midwest farmers’ pocketbooks. To explore Midwest farmers’ attitudes toward China and the trade dispute, we surveyed 693 farmers in Illinois, Iowa, and Minnesota. We found that farmers’ attitudes toward China were generally unfavourable; farmers were also somewhat pessimistic about the outcome of the trade dispute. Additionally, we found that farmers’ attitudes toward the trade dispute were driven by their disposition toward China, the information they obtained from interpersonal and media sources, the perceived credibility of media sources, their propensity to take on risks, income, and years of farming. Farmers’ attitudes toward China, on the other hand, were influenced by the degree to which they saw information sources as credible. We also found that farmers’ attitudes toward China played a mediating effect in the positive impact of media credibility on farmers’ attitudes toward the trade dispute.
MXene Confined Microcapsules for Uremic Toxins elimination
Authors: Ye Xiaomin , Yang Chaoyu , Wang Li , Fan Qihui , Shang Luoran , Ye Fang
Published: October 2023

Adsorbents with high adsorption efficiency and excellent biosafety for
biomedical applications are highly required. MXene is a promising
candidate owning these advantages, yet pristine MXene faces dilemmas
including insufficient utility of surface site as well as limited
processibility. Here, we develop MXene-encapsulated porous microcapsules
via microfluidics. The microcapsules have a biomass hydrogel shell that
provides a robust support for MXene in the core, by which the
microcapsules are endowed with high MXene dosage and remarkable
biosafety. Additionally, the MXene nanoflakes assemble into a
three-dimension (3D) network via metal ion-induced gelation, thereby
avoiding restacking and significantly improving surface utilization.
Moreover, a freeze-pretreatment of the microcapsules during preparation
results in the formation of a macroporous structure in the shell, which
can facilitate the diffusion of the target molecules. These features,
combined with additional magneto-responsiveness rendered by the
incorporation of magnetic nanoparticles, contribute to prominent
performances of the microcapsules in cleaning uremia toxins including
creatinine, urea, and uric acid. Thus, it is anticipated that the
MXene-encapsulated microcapsules will be promising adsorbents in
dialysis-related applications, and the combination of microfluidic
encapsulation with metal ion gelation will provide a novel approach for
construction of hybrid MXene materials with desired functions.
Short-wavelength-sensitive 1 (SWS1) opsin gene duplications and parallel visual pigment tuning support ultraviolet (UV) communication in damselfishes (Pomacentridae)
Authors: Stieb Sara , Cortesi Fabio , Mitchell Laurie , Queiroz Luiz Jardim de , Marshall Justin , Seehausen Ole
Published: October 2023

Damselfishes (Pomacentridae) are one of the most behaviourally diverse,
colourful and species rich reef fish families. One remarkable
characteristic of damselfishes is that they communicate in ultraviolet
(UV) light. Not only are they sensitive to UV they are also prone to
have UV-reflective colours and patterns enabling social signalling.
Using more than 50 species, we aimed to uncover the evolutionary history
of UV colour and UV vision in damselfishes. We find that all
damselfishes had UV-transmitting lenses, expressed the UV-sensitive
SWS1 opsin gene, and most displayed UV-reflective patterns and
colours. We find evidence for several tuning events across the
radiation, and while SWS1 gene duplications are generally very
rare amongst teleosts, our phylogenetic reconstructions uncovered two
independent duplication events, one close to the base of the most
species-rich clade in the subfamily Pomacentrinae, and one in an
individual Chromis species. Using amino acid comparisons, we found that
known spectral tuning sites were altered several times in parallel
across the damselfish radiation (through sequence change and duplication
followed by sequence change), causing repeated shifts in peak spectral
absorbance of around 10 nm. Pomacentrine damselfishes expressed either
one or both copies of SWS1, likely to further finetune UV-signal
detection and differentiation. This highly advanced and modified UV
vision among damselfishes, in particular the duplication of SWS1
among Pomacentrinae, might be seen as a key evolutionary innovation that
facilitated the evolution of the exuberant variety of UV reflectance
traits and possibly the diversification of this coral reef fish lineage.
Using macroinvertebrate-based biotic indices and diversity indices to assess water quality: A case study on the Karasu Stream (Kastamonu, Türkiye)
Authors: Küçükbasmacı İbrahim , Etriieki Abdulhamed M. Omar
Published: October 2023

Biomonitoring is an approach that uses indicators or sentinel species to
assess the health or pollution of an environment, combining diversity
based on specific taxonomic groups with the taxa’s indicator of
pollution into a single index or score. Benthic macroinvertebrates are
among the most preferred and valuable indicators of the biotic index.
Our study aims to evaluate water quality and ecological status using
biotic and diversity indices based on benthic macroinvertebrates. The
macroinvertebrate samples used in this study were collected seasonally
from 16 stations determined in Karasu Stream. These samples consist of
14747 specimens belonging to 9 orders and 40 families of Insecta,
Malacostraca, Hirudinea and Oligochaeta. In addition, some
physicochemical parameters were measured at the stations. The data
obtained were analyzed using the Turkey-Biological Monitoring Working
Group (TR-BMWP), Average Score per Taxon (ASPT), Family Biotic Index
(FBI), Ephemeroptera, Plecoptera, and Trichoptera (EPT) taxon richness
index, and Shannon-Wiener (SWDI), Simpson (SDI) and Hill’s diversity
indices. Our results showed that the last six stations of Karasu Stream
were under pressure due to various anthropogenic effects. According to
biotic indexes, the ecological quality status of the water in the
stations was determined to be High or Good in the first ten stations and
Average, Poor, or Bad in the last six stations. The results of our study
showed that TR-BMWP, FBI, and EPT indices are more reliable in
determining water quality than the ASPT index and reflect the
environmental situation better. Since the TR-BMWP index is adapted to
macroinvertebrate taxa distributed in Türkiye, it can be used as a
suitable tool for evaluating other rivers’ water quality in Türkiye.
Impact of socioeconomic deprivation on time to diagnosis of childhood cancer

Published: October 2023

Background: In adults, there is a link between socioeconomic status
(SES) and cancer prognosis, notably due to increased time to diagnosis
(TTD) in deprived population leading to the spread of the disease. In
children, such an association has not been clearly reported. The
objective of our study was to assess the impact of SES on TTD of
childhood cancer and its potential consequences on cancer prognosis.
Methods: We carried out a multicenter retrospective study based on the
LOGAFTER multicentric database. We studied the SES at the individual and
ecological levels. Results: Overall, 854 children were included. The
median time to diagnosis was 28 days [12;64]. A usual care pathway
did not seem to impact TTD, but the use of alternative medicine and an
initial management by professionals not usually involved in the specific
childhood cancer context increased TTD. None of the SES ecological
variables were strictly associated with a significant impact on TTD.
However, we noted strong trends for single-parent families and children
whose fathers had died who presented with an increased TTD. Conclusions:
In the current study, the impact of SES on TTD in children on both the
individual and ecological levels was not clear. However, we noted some
keys at the individual scale that require further investigation to
explain a potential association between deprivation and TTD.
Post-translational modification sites are present in hydrophilic cavities of alpha-synuclein, tau, FUS and TDP-43 fibrils: A molecular dynamics study
Authors: Kochen Noah Nathan , Seaney Darren , Vasandani Vivek , Murray Marguerite , Braun Anthony R. , Sachs Jonathan
Published: October 2023

Hydration plays a crucial role in the refolding of intrinsically
disordered proteins into amyloid fibrils; however, the specific
interactions between water and protein that may contribute to this
process are still unknown. In our previous studies of alpha-synuclein
(aSyn), we have shown that waters confined in fibril cavities are
stabilizing features of this pathological fold; and that amino acids
that hydrogen bond with these confined waters modulate primary and
seeded aggregation. Here, we extend our aSyn molecular dynamics (MD)
simulations with three new polymorphs and correlate MD trajectory
information with known post-translational modifications (PTMs) and
experimental data. Interestingly, we show that amino acids in cavities
are more stably hydrated and more evolutionarily conserved than residues
that are outside of cavities. Furthermore, amino acids in cavities that
are post-translational modification sites have on average the longest
protein-water hydrogen bond lifetimes (HBL). Utilizing the deep
mutational screen dataset by Newberry et. al. and the Thioflavin T
aggregation review by Pancoe et. al. parsed using a fibril
cavity/non-cavity definition, we show that hydrophobic changes to amino
acids in cavities have a larger effect on fitness and aggregation rate
than residues outside cavities, supporting our hypothesis that these
sites are involved in the inhibition of aSyn toxic fibrillization.
Finally, we expand our study to include analysis of fibril structures of
tau, FUS, TDP-43, prion, and hnRNPA1; all of which contained hydrated
cavities, with tau, FUS and TDP-43 recapitulating our PTM results in
aSyn fibril cavities.
Spotted hyena navigation of social-ecological landscapes on a coexistence frontier

Published: October 2023

“Coexistence frontiers”, or regions where human infrastructure and
activity are increasing rapidly or newly appearing, constitute novel
environments where wildlife must learn to navigate and coexist with
people. It is widely recognized that behaviorally flexible species are
more likely to persist in these human-dominated landscapes.
Nevertheless, we do not fully understand how these animals navigate
landscapes shaped by infrastructure, human activity, and human
tolerance. As a widely reviled and behaviorally plastic apex predator,
the spotted hyena (Crocuta crocuta) is a model species for understanding
how wide-ranging large carnivores navigate social-ecological landscapes
in an urbanizing world. Using high-resolution (minimum 5-min fix rates)
GPS collar data and supplemental camera trap imagery, we applied
resource selection and step selection functions to assess spotted hyena
landscape navigation and fine-scale movement decisions in relation to
social-ecological features in Lake Nakuru National Park and Soysambu
Conservancy, Kenya. Second, we used camera traps and barrier behavior
analysis (BaBA) to further examine hyena interactions with barriers. Our
results show that environmental covariates—including NDVI, terrain,
and proximity to water—were the best predictors of landscape-scale
resource selection by hyenas, while human infrastructure and the
likelihood of conflict with humans or livestock predicted fine-scale
hyena movement decisions. We also found that hyena selection for these
characteristics changed seasonally and across land management types.
Camera traps documented an exceptionally high number of individual
spotted hyenas (234) approaching the national park fence at 16 sites
during the study period, and BaBA results suggested that hyenas perceive
protected area boundaries’ electric fences as risky but may cross them
out of necessity. Our results highlight that wildlife adaptability in
coexistence frontiers may be expressed differently depending on context
and scale. These results also point to the need to incorporate societal
factors into multiscale analyses of carnivore movement to effectively
plan for human-carnivore coexistence.

Published: October 2023

Cancer as a terrible disease ranks among the most important healthcare
issues confronting humanity, necessitating a proactive approach to
treatment. Numerous signaling cascades are involved in the complex
process of carcinogenesis. Despite its success, chemotherapy has had
some undesirable side effects. Plants offer a rich source of novel
substances and represent an exciting new option for cancer research.
Plants and plant-derived products are revolutionizing themselves because
they are less poisonous, quicker, cheaper, safer, and simpler than
standard treatment procedures. Natural products are viewed as viable
candidates for the creation of anticancer medicines because of their
pleiotropic effects on target events in a variety of ways. The actions
of plant-derived products are selective; they damage cancer cells and
have no significant effect on healthy cells. Several researches are
being conducted on the production of potential candidates from these
plant-derived products that can stop or inhibit cancer cell
proliferation without causing adverse effects. Numerous plant-derived
products and the analogs from which they were derived have been
identified as potential anticancer therapeutic possibilities. In this
review, we summarize research on botanical products with significant and
active anticancer activity and their anticancer constituents, with a
focus on breast cancer. This review sought to highlight the most recent
advances and key successes in plant-derived products and cancer
therapies focusing on nuclear and cellular structures. Furthermore,
cancer drugs and their problems are discussed.

Kota Bandar Lampung memiliki luas wilayah 197,22 Km2 yang terdiri dari 20 Kecamatan dan 126 Kelurahan dengan jumlah penduduk pada Tahun 2021 sebanyak 1.184.949 jiwa. Kota Bandar Lampung memiliki satu infrastruktur IPLT yang terletak di Kelurahan Bakung, Kecamatan Teluk Betung Barat, Kota Bandar Lampung. IPLT ini melayani pengolahan lumpur tinja dari berbagai kecamatan yang tersebar di Kota Bandar Lampung. Wilayah ini masih menggunakan air tanah melalui sumur gali dan sumur pompa dengan cakupan 51,21% dari total jumlah rumah tangga se-Kabupaten. Oleh karena itu, dengan tingginya penggunaan sistem setempat serta penggunaan sumber air baku berupa air tanah di Kota Bandar Lampung, diperlukan pengolahan lanjutan pada sistem pengolahan air limbah domestik yang ada sekarang berupa pengurasan lumpur tinja secara rutin dan prasarana pengolahan lumpur tinja berupa IPLT. Dalam melaksanakan operasi Instalasi Pengolahan Lumpur Tinja (IPLT) di Kota Bandar Lampung terdapat beberapa masalah diantaranya adalah kurangnya pemahaman masyarakat terhadap sistem pengolahan air limbah, kurangnya kepedulian terhadap sarana dan prasarana sistem pengolahan air limbah, tidak adanya tenaga ahli yang akan menjadi operator yang memahami sistem pengolahan air limbah domestik dalam pengoperasian IPAL, dan tidak adanya SOP sistem pengolahan air limbah domestik. Tujuan penelitian ini melakukan strategi untuk peningkatan operasi dan pemeliharaan instalasi pengolahan lumpur tinja Kota Bandar Lampung
