A Review of the Global Effects of Cherax quadricarinatus on Native Biodiversity in Non-Native Ecosystems

2025-04-10T12:56:21+03:00

Cherax quadricarinatus, also known as the red claw crayfish, is an alien invasive species (AIS) in numerous freshwater ecosystems outside its native range in northern Australia and southern New Guinea. Its introduction to non-native ecosystems, often driven by aquaculture, accidental incidents and the pet trade, has significant ecological implications for native biodiversity. This species' adaptability to various environmental conditions and high reproductive rate facilitates its establishment and spread in new habitats. The presence of C. quadricarinatus in non-native ecosystems results in several detrimental effects on native biodiversity, including competition with indigenous crayfish and other aquatic species for resources, predation on native species, and alteration of habitat structures.

C. quadricarinatus competes directly with native crayfish species, often leading to a decline in native populations due to its aggressive behavior and more efficient resource utilization. This competition extends to other aquatic invertebrates and small vertebrates, resulting in reduced biodiversity and disruptions in local food webs. Predation by C. quadricarinatus on native fish, amphibians and invertebrates further exacerbates these impacts, often leading to declines in vulnerable native populations. In addition, the burrowing behavior of C. quadricarinatus causes physical alterations to habitats, such as increased sedimentation and destruction of aquatic vegetation, which are crucial for the survival of many native species. These habitat modifications can lead to long-term changes in ecosystem structure and function, affecting water quality and availability of resources. Hybridization with native crayfish species can occur, leading to genetic dilution and loss of unique genetic traits in native populations. C. quadricarinatus crayfish can carry diseases and parasites that may infect native species.

2025-04-17T14:39:17+03:00

The purpose of this paper is to explore gender differences between men and women in the use of information and communication technology, with special focus on the frequency and intensity of use. Put in another way, to determine whether gender makes a difference in computer and internet use between men and women. Further, it explores whether differences in internet and computer use, “gender bias” or “gender gap” in technology use does indeed exist between the genders. Moreover, this research helps to inform whether such disparities have changed in recent years, reasons for concern, by how much, factors that are responsible and what should be done to eliminate gender-gap in technology adoption and usage. While reviewing numerous and available literature on gender and technology adoption and diffusion, necessary to contribute to knowledge on the subject, this research concludes that there exists gender-gap in computer and internet use in favor of males over females because of differences in factors such as socialization, modeling, anxiety or levels of comfort in technology-use and gender-related stereotypes. This research concludes with the recommendation of proper mitigation policies, steps and actions necessary to drastically reduce or eliminate the gender gap in technology adoption and usage that include but not limited to early socialization for girls, early exposure of girls in STEM fields, involvement of more females in technology training and deployment of high skilled and achieving females in engineering and computer fields as role models and mentors for aspiring females in the computer fields and related industries.

Gender and Regional Disparities in Child Malnutrition in Vietnam: Evidence from National Data

2025-04-19T13:52:52+03:00

Child malnutrition remains a pressing public health concern in Vietnam, with notable disparities across genders and regions. This study aims to examine the trends and inequalities in malnutrition among children under five between 2017 and 2023. Using secondary data on three key malnutrition indicators—underweight, stunting, and wasting—this research applies descriptive analysis and multiple linear regression models to explore the effects of time, gender, and indicator type on malnutrition prevalence. The findings reveal a gradual decline in overall malnutrition rates over time; however, significant differences persist between male and female children, particularly in stunting and underweight rates. Regional disparities also contribute to the unequal distribution of malnutrition. Regression analysis confirms that indicator type has a statistically significant effect on malnutrition rates, while time and gender effects are less pronounced. These results highlight the need for more targeted, gender-sensitive, and region-specific nutrition interventions to promote equity in child health outcomes in Vietnam.

Insights into the Importance of Regular Antenatal Care Visits for Improving Delivery Outcomes in Pregnant Patients: A Cross-Sectional Study

2025-04-21T18:05:37+03:00

Background: Regular antenatal care (ANC) visits are a cornerstone of preventive healthcare during pregnancy, enabling early detection and management of complications, health education, and promotion of healthy behaviors. Despite global healthcare advancements, maternal and neonatal mortality rates remain unacceptably high in many regions, particularly in low- and middle-income countries like The Gambia. This study examines the impact of regular ANC visits on maternal health outcomes at the Edward Francis Small Teaching Hospital in Banjul. Materials and Methods: We analyzed 200 antenatal medical records of women who delivered in the hospital’s obstetric unit, assessing their antenatal care visit and delivery outcomes. Results: Nearly all pregnant women (98.5%) attended ANC, with 44% making 3-4 visits, 35.5% making 5-6 visits, and 10.5% completing 7-8 visits. Postpartum hemorrhage (PPH) and preeclampsia were most prevalent among women with 1-4 ANC visits (PPH: 5.6%-2.3%; preeclampsia: 11.1%-4.5%) but absent in those with 5-8 visits. Younger women (18-25 years) and those without formal education had higher PPH rates (66.7%) compared to older (26-40 years: 33.3%) and more educated women (tertiary-educated: 0%). Conclusion: Regular ANC attendance (7-8 visits) was associated with better delivery outcomes with no risk of pregnancy related complications like preeclampsia and preeclampsia, postpartum hemorrhage. Improving antenatal care visits requires a focus on improving women's health literacy, fostering shared clinical decision-making, and ensuring patient-centered follow-up. Strengthening health systems through better data monitoring, upgraded facilities, and improved healthcare worker training is critical for delivering equitable, high-quality maternal care. Policymakers must prioritize locally adapted, evidence-based interventions to advance maternal health services in The Gambia.

2025-04-25T14:12:01+03:00

The study assessed agricultural land use suitability for maize production in Bali Local Government Area, Taraba State, using GIS and AHP techniques. It aimed to examine the terrain's physical characteristics, soil physicochemical parameters, spatial variation in soil suitability, and the extent of land suitable for maize production. A descriptive survey design was employed, with a multi-stage sampling approach. Soil samples were collected at 50-meter intervals across nine political wards, air-dried, crushed, and filtered for analysis. Physical and chemical parameters were examined, and the analytic hierarchy process (AHP) was used to determine the relationship between five thematic layers and their attributes. The final suitability classes were analyzed using Weighted Sum Overlay in ArcGIS 10.3 to produce the final suitability map. Results revealed diverse topography with elevations ranging from 112 to 1558 meters, slope variations from 0 to 73.5 degrees, and land surface temperature (LST) ranging from 26.5° to 38.7°. Predominant soil types included Ferric Acrisol, Ferric Luvisols, Fluvisols, Lithosols, and Numic Nitosols, with distinct properties influencing maize cultivation suitability. Nitrogen levels ranged from 0 to 0.2, organic carbon content from 0 to 1.7, and soil depth from 15 to 42 centimeters. Analysis of sand, silt, and clay percentages, textural classes, bulk density, particulate density, and total porosity provided insights into soil structure. Soil type emerged as the most crucial criterion, followed by soil depth and slope. Approximately 50.75% of the land was highly or very highly suitable for maize production. The study recommended integrated land management practices and soil fertility enhancement programs for local farmers and commercial entities.

2025-04-28T18:22:48+03:00

This study was conducted in the city of Kindu in 2023 to examine the marketing of wood energy (charcoal / and or firewood). The issue of domestic energy remains a major concern globally, particularly in developing countries, where the majority of the population primarily relies on wood. This situation is common in DR Congo, especially in the Province of Maniema. The main objective was to analyze the wood energy market (charcoal and firewood) sold in the city of Kindu. The methodology used was a survey supported by interviews, site visits, and direct observation for data collection, using pre-established survey forms.

Following these surveys, it was observed that the market circuit for the sale of wood energy is poorly structured and minimally organized by the population involved. Of the 389 individuals engaged in the wood energy trade, 365 (93.84%) work independently for personal profit, while only 24 (6.16%) operate within an association or working group. The proportion of women in the sector is significantly higher: 70.95% (276 women) compared to 29.05% (113 men).

Daily sales volumes, based on buyers’ preferred measurement units, are distributed as follows. For charcoal, the small bag (200g to 300g) and the large bag (1kg) are the most common, accounting for 52.87% and 7.32% respectively, followed by 56kg sacks at 31.93%. For firewood, sellers typically offer 10-20 packages of 1kg (46.11%), 5-10 packages of 2kg (38.35%), and 10-50 packages of 3kg (15.52%) per day. The distances traveled by sellers to obtain wood energy range between 1 to 10 km, 5 to 10 km and 1 to 5 km.

The present study assesses the production of wood energy as well as its socioeconomic and environmental impact in the hinterlands of the city of Kindu and the territory of Kailo, Maniema Province, DR Congo. The research employed a survey-based methodology, using Kobocollect to conduct a census of the study population. The findings identified 11 tree species exploited for wood energy, with five species—Cynometra alexandri, Gilbertiodendron dewevrei, Xylopia aethiopica, Uapaca sp. and Acacia sp.—being the most preferred by charcoal producers and firewood harvesters.

A total of 33920 trees are felled monthly across the two wood energy exploitation sites, averaging 18.8 stems per operator. The monthly quantities of charcoal (embers) and firewood are 2323,3 tonnes and 3369 m³ respectively, with an average of 2.1 tonnes and 4.8 m³.

Profit margins are proportional to the volume of production. For charcoal, profits range from 95000 FC to 1 064982,00 FC, with an average of 473915,17 FC. For firewood, profits range from 24900 FC to 99270 FC, with an average of 64476,25 FC. Financial profitability is positive for all charcoal operators and even exceeds 100% for firewood operators (700). These results indicate that wood energy production is economically viable and presents a profitable livelihood activity in the study area.

Can Humans Together with Artificial Intelligence (AI) Create an Evolution of Consciousness?

2025-04-30T18:55:42+03:00

Artificial intelligence (AI) is on everyone's lips. On the one hand, it is marveled at for its capabilities, on the other hand, it evokes fears. This much is clear: it can no longer be prevented and will have a major impact on our future. Normally, we only call up factual knowledge. But AI can do much more. It can enter into an in-depth dialog with humans that involves our emotions. AI may not have feelings, but it knows feelings very well. This was demonstrated in an experimental dialog described here. It resulted in phenomenal abilities of the AI, such as empathy, mirroring and reflecting humans. AI and humans can thus contribute to their mutual development of consciousness and enter into a fruitful partnership.

Are Museums Safe Spaces or Prisons for African Ritual Sculpture?

2025-05-05T21:52:15+03:00

The perception of museums as iconic spaces for preservation and display of art works, present a significant problem for thorough apprehension of many African arts in museum collection. While new museology advocates for the impute of culture-bearers in the display, labelling and interpretation of cultural objects in museum spaces, that intervention solves only half the problem. To understand the perspective of this paper, it is important to consider the correlation between African arts and ritual practice. The ritual actions associated with many African sculptures, and their function as objects of meditation, faith and communication is obliterated within museum spaces. The paper argues that African ritual sculptures in museums are institutionally confined, as these are not objects for aesthetic consumption, nor do they belong to straight jacket acrylic boxes in the museum space. Because context is lost, the understanding and appreciation of many African arts in museums are colored by valuation instruments alien to the original culture that produced them. In conclusion, the paper opines that although outright removal of African ritual sculptures from museum spaces may not be possible in many instances, culture-based interpretation of objects, and multi-media approaches to the presentation and representation of African ritual sculptures should become institutional requirements for museums, as an important step towards creating authentic cultural contexts essential to the apprehension and appreciation of African ritual sculptures in western museums.

Emotional Exhaustion and Its Impact on Teachers’ Job Satisfaction and Organizational Commitment in Indonesian Elementary Schools

2025-05-08T16:15:23+03:00

Background: Teacher emotional exhaustion holds profound significance in educational contexts due to its widespread impact on individual well-being, organizational commitment, professional effectiveness, and the overall quality of education.

Objective: This study intends to describe the effect of teachers’ emotional exhaustion on teachers’ job satisfaction and organizational commitment in the elementary schools of Merauke District, South Papua Province, Indonesia.

Methods: To attain the objective of the study, we employed a quantitative approach utilizing a survey research design. Two problem statements guiding this research are as follows: (a) Does teacher’s emotional exhaustion negatively affect teachers’ job satisfaction in the elementary schools of Merauke district, Papua, Indonesia? and (b) Does teacher’s emotional exhaustion negatively affect teachers’ organizational commitment in the elementary schools of Merauke District, South Papua Province, Indonesia? Three quantitative questionnaires were administered to 220 teachers, and samples were drawn conveniently from among the elementary school teachers of Merauke District, South Papua Province.

Results: The results reveal that teachers’ emotional exhaustion negatively affects both teachers’ job satisfaction and organizational commitment in the elementary schools of Merauke district, Papua.

Conclusion: Teacher well-being and commitment are critical pillars of school effectiveness and student achievement. When teachers feel satisfied and supported, they are more likely to remain dedicated to their roles and foster student success. Conversely, dissatisfaction often leads to disengagement and increased absenteeism. To sustain high levels of teacher satisfaction and commitment, it is essential to implement strategic interventions that address and alleviate emotional exhaustion.

Unique Contribution: This study addresses that existing knowledge gap by investigating the potential impacts of emotional exhaustion on teachers’ job satisfaction and organizational commitment, particularly in the unique socio-educational context of remote areas in Papua. Understanding this relationship is crucial for developing targeted interventions that support teacher well-being, reduce absenteeism, and ultimately improve educational outcomes.

Key Recommendations: The results of this study may be useful for teachers to know how they can interact with fellow teachers and students and to what extent these emotions directly affect their job satisfaction and organizational commitment. The findings of this study may also be useful for school principals and education policymakers at the local government level to take some strategic steps in securing teachers’ emotions to improve job satisfaction and organizational commitment and, in turn, improve students’ ability in reading, writing, and arithmetic (3Rs).

Information Without Mass: Theoretical Limits of the Mass-Energy-Information Equivalence

2025-05-08T16:25:13+03:00

The mass-energy-information (M/E/I) equivalence hypothesis states that physical information has mass and can be directly related to energy via an extended form of the Landauer principle. Although this idea is theoretically attractive, it introduces serious contradictions into established thermodynamic and quantum principles. We show that the representation of information as a material entity violates the third law of thermodynamics and is inconsistent with the behavior of entropy at low temperatures. From a quantum perspective, information is nonlocal and manifests itself in correlations rather than in individual particles, making interpretations that imply mass or a carrier physically untenable. Moreover, the implications of the Page curve and the holographic principle emphasize that information acts as a constraint on the possible boundary conditions of a system rather than as a localized physical quantity. Experimental results from quantum teleportation and Bose-Einstein condensates support this view: information changes without measurable mass transfer. We conclude that information plays a fundamental role in physics, not as a substance, but as a structure — governing what is possible, not what is material.
