Biological soil crusts (referred to as biocrusts) constitute prominent components within the ecosystem of tropical coral islands in the South China Sea, covering approximately 6.25% of the island’s terrestrial surface. Biocrusts are the key to the restoration of the island ecosystem. It is widely acknowledged that phototrophic microorganisms profoundly contribute to biocrust formation and development. They provide fixed carbon and nitrogen and produce exopolysaccharides for the BSC ecosystems. Although aerobic anoxygenic phototrophic bacteria (AAPB) are an important functional group of phototrophic microorganisms, the community characteristics of AAPB in coral island biocrusts and their role in the formation of biocrusts have rarely been reported. In this study, we employed amplifications of the pufM gene to characterize the AAPB communities of biocrusts on a tropical coral island. The outcomes revealed a discernible augmentation in both the abundance and richness of AAPB concurrent with the formation of biocrusts, concomitantly with a decrement in diversity. Within the AAPB communities, the Pseudomonadota (Proteobacteria) phylum emerges as the prevailing dominion, indicating marked differentiations in terms of family and genus compositions between the biocrust and bare soil. Canonical correlation analysis has unveiled a robust and meaningful correlation between the AAPB composition and the attributes of the soil, including total nitrogen, total organic carbon, total phosphorus, pH, and calcium content. Furthermore, co-occurrence network patterns shift with biocrust formation, enhancing stability. Meanwhile, keystone taxa analysis revealed specific OTUs associated with each soil type, with genus Brevundimonas as the main group. Furthermore, pure-culture AAPB strains isolated from biocrusts exhibited a panorama of diversity, predominantly belonging to Pseudomonadota. Particularly, the Skermanella and Erythrobacter genera demonstrated strong exopolysaccharide secretion and sand-binding capabilities. This study sheds light on the significant functional role of AAPB in tropical coral island biocrusts, expanding our understanding of their contribution to ecosystem services, and providing valuable insights for ecological restoration efforts on coral islands.

Genesis 2:15 has been widely used to support both a vocational dimension of work and an earth-caring attitude that goes beyond the dominion narrative of Genesis 1:28. However, this verse has not been interpreted to ground the connection between theology of work and ecotheology. Based on the concept of Christian materialism proposed by Saint Josemaría Escrivá, we give a new interpretation to this biblical passage in order to ground the human vocation to work by linking it to the need to care for or preserve the earth. Therefore, the transformation of creation that most professional activities carry out is qualified by the duty to do it with “care”, that is, to transform the natural world with due respect for God’s original creative plan. In this way, work can become co-creative, and the transformation of nature that work entails is linked to a divine call to develop it with respect for the inner meaning of all creatures.

While most Christians might imagine the resurrection of Jesus Christ from the dead as a single event, for the author of Ephesians, the resurrection is a continuing event of cosmic proportions. In a very real way, the Epistle to the Ephesians is an extended reflection on the ongoing multidimensional cosmic consequences and transformations that result from the death of Jesus and his resurrection, whose impact not only affects the macrocosm in which Christ sits triumphantly at the right hand of God, “far above every principality, authority, power, and dominion” (Eph 1: 20–22), but also the microcosm of the Church, “his body, the fullness of the one who fills the universe in every way” (1: 23), transforming those who compose the smallest microcosm, the baptized who form a Christian household and who, gathered at table to share Eucharist (5: 17–6: 9), are “seated with Christ in the heavenly places” (2: 6), already participating in the eternal Messianic banquet. This is to say that, for this author, the resurrection of Jesus of Nazareth is the catalyst for an ongoing and ever more evolving “new creation” of humanity and, indeed, the entire cosmos, with “Christification”—the full maturation into the divine “Christ nature” (Eph 4: 13, 15–16) as the telos or goal for the whole universe (Eph 1: 10).

The ethical theories considered in this commentary include Anthropocentrism, Dominionism, Utilitarianism, Reverence for Life, Animal Rights, Biocentrism, Ecocentrism and Care Ethics. It is apparent that Utilitarianism provides a motivating rationale for devising legal instruments to manage animal welfare in many countries. The emphasis of different laws spanning many decades paralleled the trajectory of changing attitudes to animals. Initial laws focussed on serious abuse, and were enacted to deal with relative indifference to animal suffering. Anticruelty laws followed; they dealt with a wider range of noxious acts that also cause suffering. Animal Protection laws accommodated a growing acceptance that much less severe, yet still very unpleasant experiences, are of significant welfare concern. These laws and their amendments, plus the associated instruments (e.g., Codes of Welfare/Practice), were increasingly couched using animal welfare terminology. Finally, contemporary laws that focus directly to animal welfare, increasingly refer to a ‘duty of care’ towards animals, entailing responsibilities to minimise negative experiences and to promote positive ones. Outlined here is an example of an ethically-based legal structure for providing guidance and outlining requirements for animal welfare management nationally. It has four interacting levels: Level 1—Law; Level 2—Codes of Welfare/Practice; Level 3—Regulations; and Level 4—Cooperation at a National Level. It is noted that although the framing of this legal structure is based on ethical principles, the expression of those principles is more implicit than explicit. However, expression of the ethical principles can be made much more explicit when putting into effect legal requirements to assess the acceptability of different practices in animal welfare terms. There are four interacting steps in this process: Step 1—the Primary Assumption: Animals have intrinsic value and an interest in having good lives. Step 2—Distribution of Responsibility: Humans usually control human-animal interactions and have an overarching responsibility to operate two principles: (1) If in doubt err on the side of the animal; (2) If there are justified concerns, a lack of evidence can never in itself justify a practice. Step 3—Assessment of Impact on the Animals: Use a structured framework to assess the impact of human-initiated activities. The Five Domains Model is suggested as a suitable device for this. Step 4—Rigorous Evaluation: the aim, to choose the least noxious intervention as required by the Principle of Proportionality which, once chosen, supports a justification to proceed. This commentary provides examples of how ethical reasoning, and its operational consequences, can be made visible at every stage of developing, introducing and operating infrastructures for managing animal welfare nationally.

An important issue in the sustainable development of agricultural engineering today is the use of biogas plants for the production of electricity and heat from the organic waste of agricultural products and other low-quality products, which also contributes to the improvement of environmental safety. Traditional methods for assessing the apparent severity of the Roslynnytsia campaign based on statistics from the dominions proved to be ineffective. A hypothesis was proposed regarding the possibility of estimating the apparent biomass by averaging the indicators of depletion and assessing the CH₄ and CO emissions based on satellite monitoring data. The aim of this work is to create a methodology for preparing a raw material base in united territorial communities to provide them with electrical and thermal energy using biogas plants. The achievement of this goal was based on solving the following tasks: monitoring biomethane emissions in the atmosphere as a result of rotting organic waste, and monitoring carbon monoxide emissions as a result of burning agricultural waste. Experimental studies were conducted using earth satellites on sites with geometric centers in the village of Gaishin in the Pereyaslav united territorial community, the city of Ovruch in the Zhytomyr region, the Oleshkovsky Sands National Park in the Kherson region (Ukraine), and the city of Jüterbog, which is located in the state of Brandenburg and is part of the Teltow-Fläming district (Germany). The most significant results of this research involve the methodology for the preparation of the raw material base in the united territorial communities for the production of biogas, based on indirect measurements of methane and carbon dioxide emissions using the process of remote sensing. Based on the use of the proposed scientific and methodological apparatus, it was found that the location of the territory with the center in the village of Gaishin has better prospects for collecting plant raw materials for biogas production than the location of the territorial district with the center in the city of Ovruch, the emissions in which are significantly lower. From March 2020–August 2023, a higher CO concentration was recorded on average by 0.0009 mol/m², which is explained precisely by crop growing practices. In addition, as a result of the conducted studies, for the considered emissions of methane and carbon monoxide for monitoring promising raw materials, carbon monoxide has the best prospects, since methane emissions can also be caused by anthropogenic factors. Thus, in the desert (Oleshkivskie Pisky), large methane emissions were recorded throughout the year which could not be explained by crop growing practices or the livestock industry. Full article

This study explores nature’s role in the spatial development of the local Roman Catholic Church in Kikwit, a mid-size city in the Democratic Republic of Congo. Founded as a mission station by Belgian Jesuits in 1912, the local Church has experienced a peculiar development over the last century. Roman Catholic communities seem grouped spatially according to their function. Communities with apostolic functions are located in the western part of the city, while contemplative and intellectual communities are concentrated in the eastern part. The dividing line appears to be the Kwilu River, which separates the lively commercial and residential center on the left bank from more rural municipalities on the right bank. This paper proposes that this spatial organization results from the interplay of multiple theologies of nature that led to different ways of engaging with the natural surroundings in the region. Moreover, the research suggests that the Catholic Church’s transformation from a missionary institution to a (more or less) independent Church in Kikwit relied heavily on nature because it allowed further development of both the apostolic and contemplative functions of the Church.

The phenomenon conceptualized in this paper as political pentecostalism is described as a post-confessional Christian network of religious leaders and megachurches that has transformed the political scene on a global scale in the last decades. This new development represents a point of inflection in many respects within the trajectory of modern societies, particularly in the Global South, and adds new challenges to the already vexed relation between religion and civil society. Methodologically, this paper sets out to systematize the results of extensive ethnological studies about this phenomenon with the aim of reconstructing its genealogy, capturing its distinctive phenomenological traits, and distilling its central theological tenets. Defining the latter along the lines of spiritual warfare, dominion theology, and over-realized eschatology constitutes the condition for establishing as well as engaging its underlying political theology, which will be appraised in the last section. The criticism leveled there with the aid of the concepts of katechon, sovereignty, and common good is indicative of the necessity of a broader theological debate, given the multiple inconsistencies contained in its political theology, while being aware of the challenges that they pose to Christian theology as a whole.

The Doctrine of Christian Discovery is a series of fifteenth-century papal bulls that served as the theological and legal justification for the colonization of the world and the enslavement of the Original Free Nations, starting first on the African continent before spreading across the globe. In the 1800s, these bulls and other documents like The Requerimiento and colonial charters would be codified and enshrined together in U.S. law as the Doctrine of Christian Discovery, becoming the foundation of property law and international law. Also, considering what Peter d’Errico calls Federal Anti-Indian Law, we will trace and document how this framework of domination began with the Catholic crowns of Europe and transformed into the dominion theology found within Christian nationalist theologies today. Our research highlights how the Doctrine became enshrined and encoded within Protestantism and the imagined “secular” of the U.S. and Canada, countries who rhetorically espouse separation of church and state while justifying land theft, treaty violations, and the abuse of Indigenous nations and peoples through the Doctrine. We craft a genealogy of Christian domination by carefully analyzing primary sources, especially the colonial charters. We will conclude by juxtaposing the domination framework and the Haudenosaunee Confederacy’s principles of the Gayanashagowa (Great Law of Peace). Full article

Autism spectrum disorder (ASD) is a chronic neurological disorder with the severity directly linked to the diagnosis age. The severity can be reduced if diagnosis and intervention are early (age < 2 years). This work presents a novel ear-worn wearable EEG system designed to aid in the early detection of ASD. Conventional EEG systems often suffer from bulky, wired electrodes, high power consumption, and a lack of real-time electrode–skin interface (ESI) impedance monitoring. To address these limitations, our system incorporates continuous, long-term EEG recording, on-chip machine learning for real-time ASD prediction, and a passive ESI evaluation system. The passive ESI methodology evaluates impedance using the root mean square voltage of the output signal, considering factors like pressure, electrode surface area, material, gel thickness, and duration. The on-chip machine learning processor, implemented in 180 nm CMOS, occupies a minimal 2.52 mm² of active area while consuming only 0.87 µJ of energy per classification. The performance of this ML processor is validated using the Old Dominion University ASD dataset. Full article

This study investigates the theological and philosophical interplay between Rosemary Radford Ruether’s ecofeminist theology and Neo-Confucian cosmology in the context of Korean Protestant Christianity. By exploring intolerant interpretations of the Christian creation story, it critiques the anthropocentric domination of nature and proposes a reformed ecological spirituality. The research integrates Ruether’s covenantal and sacramental traditions, arguing for the significance of “relational consciousness” as a framework for eco-spiritual formation. Drawing from Ruether’s examination of creation myths and Neo-Confucian perspectives, this study asserts the necessity in reshaping Christian theology to embrace human interdependence with nature and the cosmos. It proposes that Korean Christians, influenced by Calvinist theology, must move beyond human dominion over nature to a role of co-creator and nurturer of the ecosystem, advocating for an eco-theological renewal that centers on relational consciousness for spiritual formation.

Chronic and non-communicable diseases (NCDs) account for a large proportion of global disorders and mortality, posing significant burdens on healthcare systems. Early diagnosis and timely interference are critical for effective management and disease prevention. However, the traditional methods of diagnosis still suffer from high costs, time delays in processing, and infrastructure requirements that are usually unaffordable in resource-constrained settings. Aptamer-based biosensors have emerged as promising alternatives to offer enhanced specificity, stability, and cost-effectiveness for disease biomarker detection. The SELEX (Systematic Evolution of Ligands by Exponential Enrichment) methodology allows developing aptamers with high-affinity binding capabilities to a variety of targets, for instance proteins, cells, or even small molecules, hence rendering them suitable for NCD diagnosis. Aptasensors—recent developments in the electrochemical and optical dominion—offer much enhanced sensitivity, selectivity, and stability of detection across a diverse range of diseases from lung cancer and leukemia to diabetes and chronic respiratory disorders. This study provides a comprehensive review of progress in aptamer-based sensors, focusing on their role in point-of-care diagnostics and adaptability in a real-world environment with future directions in overcoming current limitations.

Globally, climate change is causing shifts in precipitation patterns. Shifting precipitation patterns can be a stressor for many species. One species that is experiencing such stress is Helenium amarum Raf (H. Rock). H. amarum, thrives in dry upland pastures and low-lying grassy and sandy habitat in the mid-Atlantic (USA), where it persists despite storm-driven standing water. Helenium amarum is a species that is toxic to livestock and has been found outside its native range. Temperature and light impacts on germination are already known, but the role of water availability and potential ameliorating effects of mycorrhizae during water stress have not been studied. We planted seeds collected from nature in the Aquatics Facility at Old Dominion University under varied water regimes (drought, flood, intermediate) and evaluated supplemental mycorrhizal fungi impacts on plant traits. Plants in soil with supplemental mycorrhizae grew to nearly twice the height of ‘no supplement’ controls ($\overline{x}$_mycorrhizae = 23.16, S.D. = 7.33 cm; $\overline{x}$_control = 13.70, S.D. = 6.33 cm; p < 0.001). Leaf length was also greater with supplemental mycorrhizae ( $\overline{x}$_mycorrhizae = 3.52, S.D. = 1.27 cm; $\overline{x}$_control = 2.66, S.D. = 0.75 cm; p = 0.0239). Leaf number was greater in high water treatments, with supplemental mycorrhizae (high-water: $\overline{x}$_mycorrhizae = 27.47, S.D. = 10.66; $\overline{x}$_control = 13.50, S.D. = 6.80; p < 0.001; pulse-water $\overline{x}$_mycorrhizae = 30.50, S.D. = 8.64; $\overline{x}$_control = 22.38, S.D. = 7.42; p = 0.0254). This work demonstrates that H. amarum tolerates both dry and moist soil during germination, which may be relevant for successful invasiveness. Supplemental mycorrhizal fungi buffer the effects of water stress, which is significant as climate change impacts precipitation. Additionally, we have documented that pollinators frequently visit flowers of the plant, which is indicative that the species provides ecosystem services in the form of pollinator resources.

The domination (number) of a graph $G=(V,E)$, denoted by $\gamma \left(G\right)$, is the size of the minimum dominating sets of $V\left(G\right)$, also known as $\gamma$-sets. As such, the dominion of G, denoted by $\zeta \left(G\right)$, counts all its $\gamma$-sets. We proved a conjecture from one of the authors on the dominion of cycles $C_{3k-1}$ and $C_{3k-2}$, $k\ge 2$. Further, we found the formulae and recurrence relations for the dominions of several grids, $G_{m,n}$, with $2\le m\le 4$ and other results when $m\le 9$ and $n\le 20$. In general, domination and dominion play important roles in assessing certain vulnerabilities of any given network system. Full article

My Polish grandmother was sixteen when she arrived in Bolton. By the time teenagers today sit their GCSE examinations, she had travelled the distance of almost three-quarters of the globe. From Drohobycz in Poland (now modern Ukraine) following the arrest and murder of her father by the USSR’s NKVD aged 6, to a detention camp in Soviet Kyrgyzstan, to Iran, Tanganyika, and South Africa, before finally settling in England. Hers is a story of Stalin’s crimes, but it is simultaneously a story of how refugees utilised the global connections and routes created by the British Empire. It is also a postwar story of how she made a home in the nation that facilitated her wartime life. She carried with her few possessions, bar a bone letter-opener knife with an elephant carved into the handle, which she passed down to me. Bringing scholarship around refugee experiences, family histories, and material culture into conversation, this journal article seeks to achieve three things. First, it brings the story of the Polish refugees who utilised the imperial routes, colonies, dominions, and nations of British ‘interest’ to greater attention. While there has been some research into this in Britain, it has been an under-explored aspect of wartime experience which shows us as much about the war in the East as it does the inherently global nature of the war. Second, it asks what role the memory of the Polish refugee experience serves, both for those who lived through it and for subsequent generations. And finally, it addresses how this memory, beyond the Polish diaspora, might be used to explore more the nuances of life during the Second World War. Full article
