Authors: Beulah Dukanwojo Suleman  , Joshua Shaka Shaibu
Published: August 2024

The researchers investigated the perception of undergraduate students on the impact of social studies education in achieving the sustainable development goal 5 in Kogi State, Nigeria. With gender inequality persisting as a significant challenge globally, understanding the effectiveness of educational interventions like social studies education becomes paramount. This study utilized a descriptive survey design to elicit information from a target population of 583 undergraduate social studies students across two universities in Kogi State. Taro Yamane’s (1967) sampling formula was used to select a sample size of 237 students, but was increased to 267 in order to account for possible attrition with data collection. Two research questions were raised and two hypotheses were formulated and tested. The instrument for data collection was the SSEASDGGE which was validated and the reliability index of 0.855 was obtained using the Cronbach’s alpha coefficient. Descriptive statistics of mean and standard deviation were used to analyze the research questions while the chi-square test of goodness-of-fit tested the null hypotheses at a 0.05 level of significance. This study revealed amongst others that female social studies students demonstrated higher knowledge and positive attitude regarding gender roles and equality more than their male counterparts. However, the respondents reported a limited engagement in gender equality related activities outside the classroom and expressed a perceived need for improved access to educational resources and activities on gender equality. It was recommended amongst others that social studies teacher training programmes should establish partnerships with local communities and NGOs to provide students with opportunities for hands-on learning and community engagement in gender equality advocacy. This study contributes to the growing body of literature at the nexus of education and sustainable development with implications for policy, practice, and future research aimed at fostering gender equality in Kogi State and beyond.

Published: August 2024

This study advances our understanding of Ophiocordyceps, an extensively studied entomopathogenic fungus within the Ophiocordycipitaceae, particularly in Thailand. We introduce seven novel species associated with Coleoptera ? O. albostroma, O. brunnea, O. capilliformis,
O. kohchangensis, O. phitsanulokensis, O. pseudovariabilis, and O. ratchaburiensis. Remarkably, O. brunnea, O. kohchangensis, and O. ratchaburiensis exhibit ascomata on the subterminal region of the stromata, with the asexual form appearing at the apex of the stipe,
reminiscent of O. brunneipunctata. In contrast, O. phitsanulokensis produces its ascomata in the upper region of the stipe. Shared traits include immersed perithecia and part-spores production. Ophiocordyceps albostroma and O. pseudovariabilis produce pseudo-immersed
perithecia, with the former producing ascospores breaking into four part-spores, and the latter displaying 32 part-spores. Ophiocordyceps capilliformis is also introduced due to morphological distinctions from closely related species. Phylogenetic analyses based on multigene loci (LSU,
TEF1, RPB1, RPB2) robustly confirm the placement of these new species within Ophiocordyceps. Additionally, we report a new record of O. clavata in Thailand.

Authors: Tangka George Morris William , Laoh Lidya Chitra
Published: August 2024

As the energy landscape changes towards renewable energy sources and smart grid technologies, accurate prediction of peak load duration curve (PLDC) becomes crucial to ensure power system stability. The background to this research is the urgent need for more effective prediction methods to manage increasingly complex energy loads. This research presents a leading-edge approach to PLDC prediction, leveraging Deep Learning, a subsection of artificial intelligence. Focusing on data from the Taiwan State Electric Company, this study uses a Long Short-Term Memory (LSTM) network to capture complex load patterns. The LSTM model, consisting of two layers and trained on 2019-2020 data, demonstrated excellent accuracy with a Mean Absolute Percentage Error (MAPE) as low as 0.03%. These results confirm the potential of Deep Learning to revolutionize PLDC predictions in complex energy systems. These research recommendations involve exploring diverse datasets, integrating real-time data streams, and conducting comparative analyses for more reliable prediction methodologies. The benefits of this research include providing relevant insights for sustainable energy resource management amidst a dynamic energy landscape.

In recent years, the logistics industry has witnessed rapid growth, drawing considerable attention to pre-transport cargo loading as a focal point of research for scholars globally. However, the escalating complexity of actual transportation processes and the diversification of application scenarios have rendered traditional loading methodologies inadequate to meet the evolving demands of enterprises. To address this issue, this paper presents a solution to the loading problem of rectangular pulp bales in non-rectangular complex cargo holds, effectively meeting the demand for optimization algorithms and thereby conserving manpower and resources. The paper introduces a packing algorithm tailored to custom regions, which integrates the optimized Skyline algorithm with domain-search iterative strategies to achieve optimal loading outcomes. Furthermore, the efficacy of the algorithm is validated using real maritime data, demonstrating its robust performance and loading efficiency.

Authors: Gökalp Yaşar ,   The School of Health, İstanbul Medipol University, İstanbul, Turkey, Eti Serkan ,   IMU Vocational School, İstanbul Medipol University İstanbul, Turkey
Published: August 2024

Sustainable health service delivery plays a vital role for the development of countries. Sustainability of health services is associated with many factors. One of these factors is energy costs. Hospitals are buildings with high energy consumption. Accordingly, it is important to reduce energy costs in hospitals. For this purpose, it is necessary to determine the factors affecting the costs. In this way, improvements can be made without incurring very high costs. However, there are limited studies on determining the factors affecting energy costs in hospitals. Therefore, the aim of this study is to identify the important factors affecting energy costs in hospitals. In this context, the research question of the study is to determine which strategies will be implemented to reduce energy costs in hospitals. As a result of the literature review, the criteria affecting these costs are determined. The identified criteria are weighted by intuitionistic fuzzy DEMATEL method. The analysis results show that the most appropriate strategy is to reduce energy dependency with renewable energy alternatives (w=0,143). The criterion of reducing energy costs through government incentives also has an important place (w=0,136). The least influential factor is distributing informative documents on energy saving to patients/caregivers (w=0,9). Therefore, to manage energy costs in hospitals, it is appropriate to turn to renewable energy alternatives. Furthermore, government incentives such as tax exemptions are an important strategy. Establishing a good monitoring mechanism by the management would be appropriate to reduce costs.
The Replicability Crisis in Social Sciences: Do We Need a New Paradigm?
Authors: Lazić Milica
Published: August 2024

In 2016, Baker reported findings from a Nature-published study surveying 1,576 researchers at leading universities about replication challenges in their respective fields. About 70% of them reported that they had failed at least once to replicate the results of other authors' research, and about half of them had failed at least once to replicate the results of their own previously published research. However, what particularly sparked discussion in the scientific community was the fact that only 23% of them had attempted to publish their failed replications in scientific journals, while half of them were unsuccessful in their attempts—the scientific journals rejected them.The replication crisis, while present in natural sciences, has garnered more attention in social sciences and medicine, with studies revealing alarmingly low rates of reproducibility. Notably, research in fields such as psychology, economics, and various business disciplines has demonstrated significant challenges in replicating original findings, with success rates often falling below 50%. These studies have not only highlighted the pervasiveness of the replication issue across disciplines but also revealed substantial reductions in effect sizes when experiments are reproduced, underscoring the need for improved research practices and increased scrutiny of published results. These and numerous other findings have led to many questions in science, from conceptual issues to those concerning academic fraud, biases in interpreting results, post-hoc hypothesis formation (HARKing), and increasing pressure to publish. This literature review aims to examine the replicability crisis in social sciences, while also critically analyzing the role of scientific journal policies and publication pressures in exacerbating the crisis, ultimately advocating for a paradigmatic shift in research methodologies and our understanding of social phenomena.

Authors: Magnasco Angelo Arias , Lin Bochao Danae , Pries Lotta-Katrin , Guloksuz Sinan
Published: August 2024

Dissecting exposome linked to mental health outcomes can help identify potentially modifiabletargets to improve mental well-being. However, the multiplicity of exposures and the complexityof mental health phenotypes pose a major challenge. Here we conducted hypothesis-freeexposome-wide analyses to identify factors associated with 7 psychiatric diagnostic domains and19 symptom dimensions in 157,298 participants from the UK Biobank Mental Health Survey. Thecomprehensive mapping of 294 exposures revealed that several environmental factors,particularly in the domains of those previously well-studied—such as exposure to traumaticevents, childhood adversities, and cannabis use—were shared across mental health phenotypes,providing further support for transdiagnostic pathoetiology. Our findings also showed that distinctrelations might exist between particular exposures and specific mental health outcomes.Continued research into exposome through multimodal mechanistic studies guided by thetransdiagnostic mental health framework is required to better inform public health policies.

Published: August 2024

Statistical learning enables us to identify patterns in our environment and predict future events, thereby supporting a range of motor, cognitive, and linguistic skills. Despite its significance, the developmental trajectory of statistical learning has remained unclear due to a lack of comprehensive longitudinal studies. Cross-sectional research has hinted at enhanced statistical learning in children up to 11-13 years, followed by a decline into adulthood, yet definitive insights require a longitudinal approach. Our study addresses this critical gap by assessing statistical learning in the same participants at ages 7, 8, 11, and 14. Utilizing linear mixed models and latent class analyses, we observed a decline in statistical learning with age, and found that higher executive functions were associated with this decline. This study provides robust evidence that statistical learning is more effective in early childhood, offering crucial insights into the developmental trajectory of this fundamental cognitive ability.

【This is an update of preprint https://osf.io/preprints/psyarxiv/zk6db】The analogue trauma paradigm has long been used to induce flashback symptoms in healthy subjects to study the impact of stress symptoms on the performance of certain tasks. Currently, a large number of existing studies use road traffic accident videos or negative picture materials to apply this paradigm. In the field of civil aviation, stress symptoms of pilots, controllers, etc., are important factors affecting flight safety. How to explore the impact of stress symptoms of civil aviation employees on their task performance in research, the first step is to induce their stress symptoms under experimental conditions, which perfectly coincides with the application scope of the analogue trauma paradigm. However, existing research lacks material for applying the analogue trauma paradigm in the field of civil aviation, which has prevented this paradigm from being used in civil aviation-related research for a long time. Through theoretical analysis and experimental means, this article established a reliable material database of analoguetrauma paradigm can arouse flashback in the civil aviation field, and provides a reliable basis for the future application of analogue trauma paradigm in the civil aviation field.
The Alignment Between Language Properties and Computational Algorithms Enhances Statistical Word Segmentation: Evidence from Korean Child-Directed Speech
Authors: Chai Jun Ho , Mun Seongmin , Ko Eon-Suk
Published: August 2024

This study tests the hypothesis that language input directed at young children exhibits enhanced segmentability by examining the interplay between language properties in different speech registers and the performance of segmentation algorithms. Employing a speaker-matched corpus of naturalistic child-directed speech (CDS) and adult-directed speech (ADS) in Korean, we observed that Korean CDS is characterized by shorter utterances and words, lower lexical diversity, fewer hapax legomena and interjections, a more child-like nature, a higher frequency of one-word utterances, and greater lexical ambiguity than ADS. We applied multiple computational algorithms to assess the impact of these linguistic properties on word segmentation performance in both registers. The results show a significantly higher word segmentation F-score for CDS than ADS, suggesting that child-oriented linguistic adaptations in CDS facilitate easier segmentation. This observation is further supported by statistical modeling, which indicates that the enhanced segmentability in CDS is modulated by the linguistic properties of the register. Nuanced implications of the linguistic properties and their implications on the performance of segmentation algorithms are discussed.

The study evaluated the effect of including graded levels of melon shell in diets of Heterobranchus bidorsalis juveniles (15.30±1.20 g). This study was conducted for 8 weeks. The diet constitutes 42% crude protein content with melon shell at different inclusion levels of 0, 25, 50, 75 and 100% respectively. One hundred juveniles were randomly stocked into ten tanks for the five treatments in duplicate. Fish in each tank was fed 3% body weight of diet twice daily. Weights of fish were taken weekly. Data collected were analyzed using one way Analysis of Variance (ANOVA). The proximate values of the experimental diets showed a significant differences (p<0.05) among treatments. Mean Weight Gain (MWG) ranged between 97.01g in DT1 and 107.82 g in fish fed DT5. The Specific Growth Rate (SGR) ranged between 11.00%/day in fish fed DT5 and 12.98%/day in fish fed DT3. Feed Conversion Ratio (FCR) ranged between 2.01 in fish fed DT3 and 2.68 in fish fed DT1. Survival Rate (SR) ranged between 95.00% in fish fed DT1, DT3 and 100.00% in fish fed DT2, DT4 and DT5 respectively. Feed Intake (FI) ranged between 3.68 g in fish fed DT1 and 5.74 g in fish fed DT5. Result of the present study demonstrated that growth and nutrient utilization of Heterobranchus bidorsalis juveniles was significantly (p<0.05) affected by the graded level of melon shell in diet fed. It can be concluded that partial inclusion of melon shell in fish feed to supplement other carbohydrate sources is acceptable and useful in fish industry. Melon shell can be included in the diet of Heterobranchus bidorsalis up to 50% inclusion level without any adverse effect on the growth.

This study assessed socio-demographic predictors of fish farmers’ access to formal credit sources (FCSs) in Ogun West Senatorial District, Nigeria. A multistage sampling procedure was used to select 75 fish farmers. Data were elicited with an interview schedule and subjected to descriptive and inferential statistics. Results revealed that the mean age of the fish farmers was 45.25±9.362 years old and that the majority were male (88.0%), married (74.7%), had tertiary education (72.0%), non-members of cooperative societies (77.3%), practiced monoculture (94.7%), and had a household size of 1-5 persons (76.0%) with a mean household size of 5±2 persons. The highest proportion of fish farmers (64.0%) sourced the fish seeds from commercial hatcheries, while 40.0% sourced the fish seeds from their own farms. Borehole was the source of water for 76.0 % of the fish farmers, while 41.3% used well water sources. Over one-third (34.7%) had no access to any FCSs. Inadequate funding (64.0%), inadequate fish farm inputs (80.0%), and poor extension service (69.3%) were considered severe constraints to fish farming development. Results of logistic regression revealed that age (Wald = 11.826, p ≤ 0.01), membership in cooperative societies (Wald = 5.013, p≤0.05), and educational level (Wald = 5.984, p ≤ 0.05) were significant socio-demographic predictors of fish farmers’ access to formal credit sources. It was concluded that socio-demographic variables could significantly predict fish farmers’ access to FCSs. It was recommended that fish farmers should join cooperative societies and participate in the activities of their societies.

A massive decline in Hard Coral Cover has been observed in the Philippines over the past decades, and Crown-of-thorns Sea star (COTS) outbreaks contribute to this decline. Effectively managing these outbreaks will aid in conserving the country’s reefs. However, questions about the extent of the damage caused by outbreaks, the biology of the Philippine COTS, and the nature and triggers of outbreaks dramatically limit the development of effective management. This review presents the existing knowledge of the biology of the Philippine COTS, past and present COTS outbreaks in the country, and current management strategies used to control these outbreaks. An extensive literature search was done to consolidate historical reports of COTS outbreaks from published journal articles, news articles, and personal communication with government agencies and other organizations. Results showed that COTS was reported in the Philippines as early as 1938, but outbreaks have been documented for the past five decades. COTS outbreaks have been consistently reported in the waters of Cebu, Central Visayas from 2002 to 2008 and 2018 to 2021. COTS spawning in the Philippines was reported during the summer months from March to May, but further studies are needed on other aspects of its biology, especially on its morphology, reproductive capacity, larval biology, and feeding capacity. Lastly, a Philippine COTS management program involving the government, the academe, and citizen scientists is urgently needed to monitor COTS outbreaks and minimize its effects on the country’s ailing reefs.

Freshwater prawns of the genus Macrobrachium are among the most valuable cultured aquatic species in the world. The systematic study of Macrobrachium species in the Philippines has often been based on morphological trait assessment. Here, we combined morphology and molecular approaches to study the presence and actual distribution of Macrobrachium species along the Cairawan River in Laua-an, Antique Province, Panay Island. Using morphological characteristics, we identified 11 Macrobrachium species, the highest number of species reported from a single river. Molecular results based on the cytochrome oxidase subunit I (COI) mitochondrial DNA (mtDNA) sequences confirmed the morphological identification. The analysis revealed eight major clades with 19 distinct haplotypes within the species. Our results provide information on the identification of Macrobrachium species inhabiting the Cairawan River. The baseline information can be helpful for future genetic studies involving freshwater prawns with potential use in aquaculture. It can provide scientific data to facilitate the formulation of selective breeding plans and direct governance policies in freshwater prawn resource conservation and management in the Philippines.

Pine pollen is an example of phytoandrogen that has been utilized as a feed additive for all animals worldwide and used as an alternative to hormone replacement therapy that can safely restore healthy testosterone levels in men. Previous on-farm trials demonstrated the effectiveness of Benguet pine pollen (Pinus kesiya) as an alternative hormone source for the sex redirection of tilapia. The study characterized phytoandrogen four types of pine pollen, coded as PPL1 (Benguet 1), PPL2 (Benguet 2), PPC1 (commercially available in cracked form), and PPC2 (commercially available in whole form). The characterization showed the differences in morphology and particle size in micrometer scale under the scanning electron microscopy (SEM) analysis. Meanwhile, Energy dispersive X-ray (EDX) analysis determined that the Benguet and commercial pine pollen contains carbon, oxygen, nitrogen, and potassium. All samples have strong elemental bonding based on FTIR analysis. Pine pollen with cracked cell walls has the smallest particle, around 35.48 μm, and it was significantly different among all other samples at p<0.05. The particle size of characterized pine pollen ranged from 35.48±0.87 to 46.72±3.67 μm, which can be used for an efficient drug delivery system. Additionally, a stable particle was produced after intercalation was applied. Moreover, the study found that all pine pollen samples were good sources of phytoandrogen levels 1.25 x 106, comparable to testosterone; this can be a good replacement for 17 α -MT in aquaculture, making it sustainable and safe for the environment.
