Investigation of the interactions among preschool teachers' components of pedagogical content knowledge for early science teaching
Authors: Kutluca Ali Yiğit
Published: November 2024

The purpose of this case study is to explore the pedagogical constructions of preschool teachers towards science teaching and the interactions between pedagogical content knowledge (PCK) components. PCK Mapping, which is a pictorial methodological approach, has been used to reach this purpose. The case addressed in this study is to understand the nature of the interaction between the PCK components that preschool teachers use while planning and implementing the yoghurt-making activity. In order to better understand this case, six preschool teachers from different experiences participated in the study. This design is a multiple case study as the PCK conceptualization of each participant represents a different case. The data in the study were collected through Content Representations (CoRes) and Instruction Based Interviews. All participants first planned a science teaching activity (making yoghurt) through CoRes, then answered questions about their teaching background, science teaching orientations and the activity. Afterwards, interviews were made about the pedagogical tools they used while structuring the teaching. Finally, each teacher was observed and videotaped while teaching the yoghurt-making activity. After the observations, Video-Stimulated Recall interviews were made with them. Data were analysed through in-depth analysis of explicit PCK, enumerative approach, PCK mapping and the constant comparative method. The results show that preschool teachers use children's cognitive potentials, teaching strategies, and epistemological and pedagogical orientations while planning and implementing science teaching and they frequently associate them. In addition, preschool teachers have a lack of linking curriculum materials with science teaching and other PCK components.

All children have the right to a safe and nurturing environment that promotes their holistic development. Accessibility is an important gateway to inclusive education where all children including disadvantaged children such as indigenous children, special needs children and children at risk are given equal access to quality early childhood care and education (ECCE). In ensuring inclusive accessibility to ECCE, many countries including Malaysia have instituted policies in relation to the provision of childcare and preschool education. These policies are expected to make a significant difference to the way practitioners work to achieve the best outcomes. This paper reports on a research study to examine the impact of the existing policies on the accessibility to quality ECCE in Malaysia. As part of a larger research project, this study employs a qualitative methodology that used a purposive sampling method. 54 participants were involved consisting government official and leaders of non-government agencies related to ECCE in Malaysia. A team of researchers conducted individual interviews and focus group interviews for the participants who consented to the research. Data collected were transcribed verbatim and analyzed using inductive thematic analysis method involving three cycles of rigorous analytic coding and review processes. The findings of this study indicated the participants are aware of the accessibility related policies they are directly dealing with, and the major themes expressed were inter-agency cooperation to achieve enrolment target; questioning the status quo of the existing procedures; and challenges in providing support services for children with special needs; and inclusion of children with disabilities. The challenges to accessibility are mostly related to disadvantaged children and weakness in the governance and gaps of implementation. Policy reviews need to be systematized into programme planning to ensure high quality ECCE services are accessible to all children in Malaysia.

Published: November 2024

Children start to gain concepts from an early age. They are particularly sensitive to what is happening in their close surroundings. As a result of their daily observations, they can create various conceptual information about the Earth, Sun, and Moon. It is thought that the participation of children in the education process is very important for this information to become basic. The aim of this study is to reveal the variation in knowledge levels about the concepts of the Earth, Sun, and Moon of students who do or do not take preschool education. The research is qualitative, and it was conducted with a total of 40 students aged 6-7. In order to collect the data, we created and used a semi-structured interview form. With this form, students' information about the shapes, movements, colors, and dimensions of the Earth, Sun, and Moon were collected. In the analysis given, content analysis was used, and the answers given were expressed as percentage and frequency. As a result of this study, we concluded that the students who take preschool education were more knowledgeable about the information, expression, explanation, and analogy of the concepts of Earth, Sun, and Moon and their shapes, colors, movements, and dimensions than were the students who did not have a preschool education.

Published: November 2024

The consumption of chocolate, especially varieties high in sugar, can disrupt the delicate pH balance in the oral cavity, increasing the risk of dental caries. Pineapple, with its rich enzymatic and organic acid profile, presents a potential natural solution to counteract this acidic challenge. This study investigates the efficacy of pineapple consumption in mitigating the pH-lowering effects of chocolate and its impact on saliva volume, a crucial factor in maintaining oral health. A quasi-experimental design with a pre-test and post-test control group approach was employed. Participants included children aged 6-9 years (n=40), divided into two groups: a control group (chocolate consumption only) and an intervention group (chocolate consumption followed by pineapple consumption). Saliva volume and pH were measured before and after treatment, and the data were analyzed using paired t-tests. Pineapple consumption significantly increased saliva volume in the intervention group (from 2.01±1.29 mL to 5.3±0.88 mL, p<0.05), exceeding the volume observed in the control group. Furthermore, the decrease in saliva pH in the intervention group (from 7.45±0.13 to 6.25±0.37) was more controlled compared to the control group (from 7.30±0.09 to 5.28±0.25). In conclusion, the consumption of pineapple after chocolate effectively stimulates saliva production and helps maintain a balanced oral pH, mitigating the acidic effects of chocolate and potentially reducing the risk of dental caries. These findings suggest the potential of pineapple as a natural, dietary approach to support oral health.
The promises and perils of circulating tumor DNA for monitoring immunotherapy response in non-small cell lung cancer
Authors: Hebert Brandon Joseph , Bradley James
Published: November 2024

There has been a rapid expansion of immunotherapy options for non-small cell lung cancer (NSCLC) over the past two decades, particularly with the advent of immune checkpoint inhibitors. Despite the emerging role of immunotherapy in adjuvant and neoadjuvant settings though, relatively few patients will respond to immunotherapy which can be problematic due to expense and toxicity; thus, the development of biomarkers capable of predicting immunotherapeutic response is imperative. Due to the promise of a noninvasive, personalized approach capable of providing comprehensive, real-time monitoring of tumor heterogeneity and evolution, there has been wide interest in the concept of using circulating tumor DNA (ctDNA) to predict treatment response. Although the use of ctDNA to detect actionable mutations such as EGFR is now integral in the standard of care for patients with NSCLC, several large studies have also shown its potential as a biomarker of immunotherapeutic response. Ongoing ctDNA interventional clinical trials, such as the BR.36 trial, will help to clarify the potential role of ctDNA for therapeutic guidance. Despite the promise of this technology, there are many limitations and considerations that clinicians need to be aware of prior to widespread implementation in clinical practice, such as the effect of underlying comorbidities, ctDNA fraction, stage of underlying malignancy, and concordance between aberrations detected in ctDNA and tumor tissue.
Computing Method Applied for Simulation and Forecast of Hydrophysical Fields in the Southeastern Black Sea
Authors: Demetrashvili Demuri
Published: November 2024

In this paper, a numerical regional model of the Black Sea hydrodynamics with a spatial resolution of 1 km is applied to simulate and forecast the mesoscale circulation and thermohaline structure in the southeastern part of the Black Sea. The regional model is based on a nonlinear nonstationary system of differential equations in z coordinates, describing the evolution of three-dimensional fields of currents, temperature, salinity, and density. The solution of the equation system is based on the use of finite-difference methods, in particular, on the method of multicomponent splitting of the differential operator of the original problem into simpler operators. To illustrate the implementation of the numerical model, the paper presents the calculated fields of flow, temperature, and salinity for the summer season of 2020 under real atmospheric forcing derived from the atmospheric model SCIRON. The influence of basin-scale processes on regional processes was taken into account by boundary conditions on the liquid boundary separating the regional area from the open part of the sea basin. A comparison of the forecast results with available satellite data shows that the model reproduces well the basic peculiarities of hydrophysical fields.
Оскорбление высшей власти крестьянами и мещанами Стародубья в конце XIX века
Authors: О.А. Музыченко
Published: November 2024

Актуальность темы исследования обусловлена малым количеством работ по теме оскорбления власти представителями непривилегированных сословий во второй половине XIX века в России, а также отсутствием специальных работ по теме оскорбления власти крестьянами и мещанами Стародубья в конце XIX века. Вместе с тем данная тема является важной, поскольку раскрывает в ретроспективе некоторые особенности менталитета жителей одного из регионов нашей страны — юго-западной Брянщины. Цель исследования — выявить причины и обстоятельства оскорбления высшей власти крестьянами и мещанами Стародубья. Объектом исследования в настоящей статье выступает отношение к власти представителей непривилегированных сословий в пореформенный период. Предмет исследования — оскорбление высшей власти крестьянами и мещанами Стародубья в конце XIX века. В результате исследования было выявлено, что причиной оскорбления высшей власти со стороны жителей Стародубья являлся целый комплекс сословных проблем. У бывших помещичьих крестьян эти проблемы были связаны с трудностями выплаты выкупных платежей и нехваткой земли, а у мещан региона — с невозможностью платить сословные сборы. Оскорбления в адрес власти обычно звучали во время ссор и споров, а также в ходе разговоров, где крестьяне и мещане делились своими проблемами и одновременно бранили власть.

The relevance of the topic is due to insufficient research about insulting of Russian authorities by members of the unprivileged classes in in the second half of the 19thcentury, as well as lack of special works on the topic of insulting the authorities by peasants and townspeople of Starodubye at the end of the 19th century. At the same time, this topic is important because it reveals in retrospect some features of the mentality of local residents of the southwestern Bryansk area. The purpose of the study is to identify the causes and circumstances of insulting the supreme authority by peasants and townspeople of Starodubye. The object of research is the attitude of the unprivileged classes to the authorities in the post-reform period. The subject of the study is insulting the supreme authority by peasants and townspeople of Starodubye at the end of the 19th century. As a result of the study, it was revealed that the reasons for insulting the supreme authority by the inhabitants of Starodubye display a whole range of class problems. For the landlords’ former serfs, these problems were related to the difficulties of paying redemption sums and a shortage of land, and for the townspeople of the region, to the impossibility of paying class duties. Insults addressed to authorities were usually voiced during quarrels and disputes, as well as during conversations where peasants and townspeople shared their problems and scolded the authorities.

Fostering Workforce Readiness for the Green Hydrogen Economy through People-Centric Training Programs
Authors: Henry Ebini Olajide
Published: November 2024

One of the most important ways to cut carbon emissions and fight climate change is to switch to green hydrogen, a clean energy source made by electrolysis using renewable resources. A significant obstacle to this shift, nevertheless, is the lack of a trained labor force that can handle the complexity of hydrogen technologies. In addition to addressing technical skills, this study highlights the importance of a people-centric approach to workforce training that promotes flexibility, creativity, and lifelong learning. Organizations can bridge the skills gap and promote sustainable growth in the green hydrogen economy by giving individual learning needs and career development priority. This study examines the important connections between training accessibility, skills acquisition, institutional support, and workforce preparation using both theoretical and empirical data. The findings reveal that fostering familiarity with green hydrogen concepts significantly enhances skill acquisition and readiness to transition into this evolving sector. Furthermore, the study identifies major barriers to training—namely cost, inaccessibility, and time constraints—and suggests that hybrid and online training models, supported by strong institutional partnerships, offer the most effective solutions. This paper concludes by proposing a people-centric training framework that can empower the workforce to meet the demands of the green hydrogen economy, ultimately contributing to a just and efficient energy transition.

In 1690 Charles, second duke of Schomberg, joined the Grand Alliance of Britain, the Dutch Republic, Spain and the Holy Roman Emperor that was engaged in a war with France. In April 1691 Schomberg was appointed lieutenant-general of five Huguenot regiments, paid for by the British and the Dutch, designed to give military support to Victor Amadeus II, duke of Savoy-Piedmont. By invading Dauphiné, William III hoped that these Huguenot regiments would incite their co-religionists living there to rise against Louis XIV and force the French king to a reasonable peace. Schomberg’s military career in Savoy-Piedmont was anything but successful. His relationship with Victor Amadeus was very strained and the invasion in 1692 failed to provoke a Huguenot revolt. When Louis XIV strengthened his Italian army the following year, Nicolas de Catinat, the French commander, defeated Victor Amadeus’s much weaker army at Marsiglia on 4 October 1693. Schomberg was so heavily wounded during the battle that he died a fortnight later.

The High-Energy Particle Detector (HEPD-01) on board the China Seismo-Electromagnetic Satellite, located on a Sun-synchronous orbit at 500 km of altitude with an inclination of 97°, features a dedicated logic counting low-energy event rates, which proved sensitive to intense Gamma-Ray Burst (GRB). The present work reports a comprehensive analysis of signals induced by GRBs in the event-rate data collected between 2018 August and 2022 June. After accurately modeling the background rate as observed in different passages of the satellite over the same geographical area, we detected significant deviations to be compared with observations of GRB candidates from other observatories. The analysis revealed 12 statistically significant excesses, that have been associated with GRB 181222B, GRB 190114C, GRB 190129B, GRB 190305A, GRB 190928A, GRB 200412B, GRB 200422A, GRB 200826B, GRB 201009A, GRB 210702A, GRB 211211A, and GRB 220624A. We report light curves for 0.3–50 MeV photons, comparing them with findings from other space telescopes. The catalog of observations is published, complete of GRB observation time, duration, integrated counts, and fluence.

Galactic bars induce characteristic motions deviating from pure circular rotation, known as noncircular motions. As bars are nonaxisymmetric structures, stronger bars are expected to show stronger noncircular motions. However, this has not yet been confirmed by observations. We use a bisymmetric model to account for the stellar kinematics of 14 barred galaxies obtained with the Multi-Unit Spectroscopic Explorer and characterize the degree of bar-driven noncircular motions. For the first time, we find tight relations between the bar strength (bar ellipticity and torque parameter) and the degree of stellar noncircular motions. We also find that the bar strength is strongly associated with the stellar radial velocity driven by bars. Our results imply that stronger bars exhibit stronger noncircular motions. Noncircular motions beyond the bar are found to be weak, comprising less than 10% of the strength of the circular motions. We find that galaxies with a boxy/peanut (B/P) bulge exhibit a higher degree of noncircular motions and higher stellar radial velocity compared to galaxies without a B/P bulge, by 30% ∼ 50%. However, this effect could be attributed to the presence of strong bars in galaxies with a B/P feature in our sample, which would naturally result in higher radial motions, rather than to the B/P bulges themselves inducing stronger radial motions. More observational studies, utilizing both stellar and gaseous kinematics on statistically complete samples, along with numerical studies are necessary to draw a comprehensive view of the impact that B/P bulges have on bar-driven noncircular motions.

A pulsar’s scintillation bandwidth is inversely proportional to the scattering delay, making accurate measurements of scintillation bandwidth critical to characterize unmitigated delays in efforts to measure low-frequency gravitational waves with pulsar timing arrays. In this pilot work, we searched for a subset of known pulsars within ∼97% of the data taken with the Puerto Rico Ultimate Pulsar Processing Instrument for the AO327 survey with the Arecibo telescope, attempting to measure the scintillation bandwidths in the data set by fitting to the 2D autocorrelation function of their dynamic spectra. We successfully measured 38 bandwidths from 23 pulsars (six without prior literature values), finding that: almost all of the measurements are larger than the predictions from NE2001 and YMW16 (two popular galactic models); NE2001 is more consistent with our measurements than YMW16; Gaussian fits to the bandwidth are more consistent with both electron density models than Lorentzian ones; and for the 17 pulsars with prior literature values, the measurements between various sources often vary by a few factors. The success of Gaussian fits may be due to the use of Gaussian fits to train models in previous work. The variance of literature values over time could relate to the scaling factor used to compare measurements, but also seems consistent with time-varying interstellar medium parameters. This work can be extended to the rest of AO327 to further investigate these trends, highlighting the continuing importance of large archival data sets for projects beyond their initial conception.

Recent observations by JWST yield a large abundance of luminous galaxies at z ≳ 10 compared to that expected in the ΛCDM scenario based on extrapolations of the star formation efficiency measured at lower redshifts. While several astrophysical processes can be responsible for such observations, here we explore to what extent such an effect can be rooted in the assumed dark energy (DE) sector of the current cosmological model. This is motivated by recent results from different cosmological probes combined with the last data release of the Dark Energy Spectroscopic Instrument, which indicate a tension in the DE sector of the concordance ΛCDM model. We have considered the effect of assuming a DE characterized by a negative Λ as the ground state of a quintessence field on the galaxy luminosity function at high redshifts. We find that such models naturally affect the galaxy UV luminosities in the redshift range 10 ≲ z ≲ 15 needed to match the JWST observations, and with the value of ΩΛ = [−0.6, −0.3] remarkably consistent with that required by independent cosmological probes. A sharp prediction of such models is the steep decline of the abundance of bright galaxies in the redshift range 15 ≲ z ≲ 16.
