Accessible Literacy for Emerging Communicators: A Proposed Model and Case Application With Children on the Autism Spectrum
Authors: DeLuca Tim , Boucher Alyssa , Holyfield Christine
Published: November 2024

Purpose:

Opportunities for literacy learning should be made accessible to all. For children with developmental disabilities who are emergent communicators, instruction in language and word reading may not be accessible through traditional practices.

Method:

Within this clinical focus article, we propose a conceptual model—accessible literacy for emerging communicators (ALEC)—guided by universal design for learning (UDL). UDL provides guidance to make learning accessible by considering all students' needs for engagement, representation, and action and expression. The ALEC model leverages UDL to offer clinical guidance to identify and implement opportunities for language and word reading learning for emerging communicators using augmentative and alternative communication. For emerging communicators with developmental disabilities, applying UDL principles to literacy opportunities includes mapping literacy onto meaningful interactions, providing high-meaning and orthographic representations, and embedding literacy into augmentative and alternative communication technology. We explore this approach clinically, reporting on cases in which we used the approach with three young children on the autism spectrum.

Results:

Based on clinical observation of data collection sessions in which UDL principles were applied to literacy, three participants demonstrated improved engagement compared with other sessions that targeted literacy goals.

Conclusion:

More research is needed, but our initial exploration showed that, by applying UDL guidelines for access, literacy learning opportunities can be made accessible for children with developmental disabilities who are emerging communicators.
MOEA/D‐based multi‐row facility layout optimisation method with discontinuity perceiving of the Pareto front
Authors: Guo Yinan , Huang Yao , Cheng Jian , Ban Xiaoyu , Zhao Xiaoxiao , Liu Tianyu
Published: November 2024

In a multi‐row facility layout problem (MRFLP), facilities are arranged in more than one row under the limited layout area. Considering different layout factors, various extensions of MRFLP have been modelled. However, the orientation of input/output (I/O) point in a facility, as a key factor that plays a direct impact on flow cost, is seldom taken into account. Hence, a novel MRFLP is formulated to minimise both the layout area and flow cost, in which the position of I/O point is employed to calibrate the position of a facility and its orientation determines the flow cost for transporting materials among facilities. To solve the problem, a decomposition‐based multi‐objective evolutionary algorithm with perceiving discontinuity characteristic of Pareto front (PF) is put forward. After judging the discontinuity of PF, the weight vectors are adjusted to enhance the exploitation in continuous regions. To avoid premature convergence, a re‐initialisation mechanism is introduced to help the population jump out of the local optima. Moreover, an improved adaptive epsilon constraint‐handling technique is designed to effectively balance the diversity and feasibility of a population during the evolution. Experimental results of 12 instances expose that the proposed algorithm outperforms other state‐of‐the‐art algorithms significantly.

State‐of‐the‐art model‐based predictive control techniques for AC motor drives are reviewed in this paper. A plethora of MPC algorithms with vast number of complex ideas has emerged in the last decade and this work makes an attempt to present those concepts in an intuitive, comprehensive and hierarchical manner. More emphasis is laid on finite control set model predictive control (FCS‐MPC) methods, especially predictive torque control (PTC) and predictive current control (PCC) because of their emergence as the prime focus of ongoing research in energy efficient drive control. The main focus of this review is to analyse the most recent work, signpost the future research directions, identify the core challenges and consolidate the ideas into a coherent and concise reference. A comprehensive classification based on actuation signals is presented and reviewed in detail. Then, the important challenges in MPC implementation, such as computational complexity reduction and delay compensation, weighting factor selection for multi‐objective cost functions, steady state performance and ripple reduction, parameter variations/model mismatching and achieving extended prediction horizons, are surveyed and most relevant solutions are reviewed. A detailed analysis of the last five years related work is given at the end and it is concluded that the future course seems to be diverting towards voltage vector selection with optimised phase, magnitude and duty ratios. Computational burden is still one of the main hurdle towards MPC proliferation and adaptation in AC drive control at the industrial level. However, with advent of high speed and cheaper signal processors and development of efficient algorithms, MPC is rapidly becoming the control method of choice for energy‐efficient drive control.
The age of the Methuselah star in the light of stellar evolution models with tailored abundances
Authors: Guillaume C. , Buldgen G. , Amarsi A. M. , Dupret M. A. , Lundkvist M. S. , Larsen J. R. , Scuflaire R. , Noels A.
Published: November 2024

Context. HD140283, or the Methuselah star, is a well-known reference object in stellar evolution. Its peculiar chemical composition, proximity and absence of reddening makes it an interesting case-study of Pop II stars. Thanks to recent observational efforts, we now have precise interferometric and spectroscopic constraints, as well as revised astrometric parallaxes from the Gaia mission.

Aims. We determine the age of HD140283 with these latest constraints, and we quantify the impact of systematics from physical inaccuracies on the stellar evolution models.

Methods. Using recent spectroscopic abundances from the literature, including 3D non-local thermal equilibrium values for C, O, and Fe, we computed opacity tables specific to HD140283. We then used them in grids of stellar evolution models coupled to a Markov chain Monte Carlo tool to determine the age of HD140283.

Results. With our tailored models we found an age of 12.3 Gy. When we instead used a solar-scaled mixture, we found an age value of 14 Gy, which contradicts theories about the age of the Universe (13.77 ± 0.06 Gy). We also found that a reduction of the mixing-length parameter from its solar calibrated value leads to an even younger age, and this agrees with other recent studies. However, we found no direct evidence that would favour a lower value of the mixing-length parameter based on our modelling.

Conclusions. It is crucial to take the specific elemental abundances into account to model HD140283 because this leads to significant differences in the inferred age. However, this effect is degenerate with a decreasing mixing-length parameter. In this respect, asteroseismic constraints might play a key role in accurately deriving the mass of HD140283, and therefore, in strongly constraining its age.

Published: November 2024

This study explores factors impacting the effectiveness of forest protection policies in Indonesia, focusing on legal regulatory norms. Field findings reveal that community members continue cutting down trees due to economic need and limited awareness of forest protection policies, contributing significantly to forest degradation. To examine these factors, data were gathered through purposive sampling, targeting respondents— primarily farmers and cultivators—engaged in wood harvesting. Questionnaire results highlight economic motives and lack of policy knowledge as main drivers of logging, with many respondents indicating limited familiarity with policy specifics regarding forest conservation.The study also reviews the enforcement of existing sanctions, such as administrative penalties, fines, and imprisonment, and their effect within societal norms. The findings suggest that current sanctions have yet to effectively curb violations. Based on these observations and a policy review, this study proposes incorporating local wisdom into forest protection strategies and introducing more impactful social sanctions to strengthen policy effectiveness. This research contributes to understanding regulatory challenges in forest conservation and suggests pathways to enhance policy enforcement through culturally sensitive approaches and tailored sanctions.

Authors: Gunawan Yordan
Published: November 2024

The Israeli-Palestinian conflict has severely impacted Gaza’s environment, worsening its humanitarian crisis. This study examines the environmental consequences of Israeli military actions through International Environmental Law, using normative legal research methods. It identifies extensive damage, including soil degradation, air pollution, water contamination, biodiversity loss, and significant health impacts. Expert testimonies highlight the long-term devastation. Despite international frameworks like Protocol I of the Geneva Conventions and the ENMOD Convention, enforcement challenges hinder effective environmental protection. The International Law Commission’s draft principles on Protecting the Environment in Armed Conflicts offer potential solutions, but implementation remains difficult. The global community must provide technical assistance and financial support for Gaza’s recovery and hold Israel accountable under International Environmental Law to ensure justice and prevent further harm. Sustainable reconstruction, combined with adherence to legal standards, is crucial for Gaza’s future resilience. This paper urgently calls for robust legal and policy frameworks that integrate environmental and humanitarian concerns. Strengthening these frameworks can help safeguard the environment in conflict zones, promoting a sustainable and just future for affected populations.

The production of essential oil from clove leaves in Samigaluh, Yogyakarta, generates waste that is slow to decompose and accumulates, posing environmental challenges. The disposal of this waste into rivers threatens aquatic habitats and exacerbates pollution in local communities. In collaboration with the Adi IAI Foundation, a study was conducted to explore the potential use of clove leave essential oil waste in the production of non-burning interlock bricks. This research aims to evaluate the economic viability of utilizing clove leaf waste as a raw material in brick manufacturing. The study involved analyzing the cost-benefit structure of using waste material compared to traditional brick making methods. Factors such as production costs, material availability, environmental impact reduction, and potential market demand were evaluated. Findings from this economic analysis show promising results, indicating a reduction in both raw material costs and environmental pollution. The utilization of clove leaf waste not only addresses a significant environmental concern but also offers an economically sustainable alternative for local industries. The integration of clove leaf essential oil waste into brick-making processes could serve as a viable waste management strategy while supporting environmentally sustainable economic development. Policymakers should encourage similar eco-friendly innovations in other waste-producing industries

The purpose of this study was to determine the effect of microbe consortium on the physical characteristics of pools water and the growth of vannamei shrimp. The experiment was arranged in a Completely Randomized Design consisting of five types of microbe consortium treatments including Trichoderma, Lactobacillus, probiotic bacteria, Trichoderma-Lactobacillus, and Trichoderma-probiotic bacteria with a population density of 0.5x104 CFU.mL-1 for fungi and 104 CFU.mL-1 for bacteria. A total of 5,000 shrimp seeds were planted in each of the 15 circular pools with a volume of 12.56 m3. The parameters observed were pH, temperature, salinity, dissolved oxygen, water brightness, as well as Average Daily Growth (ADG), and Feed Conversion Rate (FCR). The data were analyzed through ANOVA followed by a 5% LSD test, and correlation analysis was also conducted. The results showed that Trichoderma either alone or in combination with the probiotic bacteria and Lactobacillus spp., increased the pH, temperature, salinity, dissolved oxygen, and water brightness as well as shrimp’s daily growth and feed utilization efficiency. ADG value has a positive correlation with the average increase in pH and water clarity. Meanwhile, FCR correlated with an elevation in ADG and pH, as well as a decrease in water brightness.

The shelf life of consumer eggs is only 7-14 days. Chitosan coating technology is one approach for increasing the shelf life of consumer eggs. To boost the hydrophobicity of the chitosan solution, oil must be added. The study sought to investigate the extension of shelf life and internal quality of fresh eggs through cleaning and coating with chitosan and rice bran oil (RBO). Treatments evaluated included controls, cleaners and non-cleaners, coating and non-coating Chitosan, and RBO. Weight loss, egg yolk index, egg white index, haugh units, and pH levels were all recorded. Observations were conducted for seven weeks. The research results showed that coating rice bran oil without sanitizer had the lowest weight loss and egg pH, which were 1.99% and 8.3, respectively. The rice bran oil coating treatment without sanitizer had the greatest egg white and HU indexes, respectively 0.04 and 62.57, while the rice bran oil coating treatment with sanitizer had the highest egg yolk index, 0.32. Without sanitizer, the chitosan and rice bran oil coating treatment outperformed the control and other treatments in terms of egg shelf-life extension.
