Rapid decarbonization relies on knowing which structural and energy factors affect national carbon dioxide emissions. Much of the literature leans on linear and additive assumptions, which may gloss over curvature and interactions in this energy–emissions link. Unlike previous studies, we take a different approach. Using a panel of 80 high- and upper-middle-income countries from 2011 to 2020, we model emissions as a function of fossil fuel energy consumption, methane, the food production index, renewable electricity output, gross domestic product (GDP), and trade measured as trade over GDP. Our contribution is twofold. First, we evaluate how different modeling strategies, from a traditional Generalized Linear Model to more flexible approaches such as Support Vector Machine regression and Random Forest (RF), influence the identification of emission drivers. Second, we use Double Machine Learning (DML) to estimate the incremental effect of fossil fuel consumption while controlling for other variables, offering a more careful interpretation of its likely causal role. Across models, a clear pattern emerges: GDP dominates; fossil fuel energy consumption and methane follow. Renewable electricity output and trade contribute, but to a moderate degree. The food production index adds little in this aggregate, cross-country setting. To probe the mechanism rather than the prediction, we estimate the incremental role of fossil fuel energy consumption using DML with RF nuisance functions. The partial effect remains positive after conditioning on the other covariates. Taken together, the results suggest that economic scale and the fuel mix are the primary levers for near-term emissions profiles, while renewables and trade matter, just less than is often assumed and in ways that may depend on context.

This study investigates instances of conflation and misattribution in the transmission of three Chinese Buddhist catalogues that share the title Zhongjing mulu 眾經目錄 (Catalogue of Various Scriptures), attributed, respectively, to Fajing 法經, Yancong 彥琮, and Jingtai 靜泰 during the Sui and Tang dynasties. Although these catalogues differ in structure, doctrinal classification, and historical context, their identical titles and overlapping content may have led to instances of conflation in the editorial processes of later Buddhist canons. This phenomenon is revealed and analyzed in the present study. Drawing primarily on the phonetic glosses appended to fascicles (suihan yinshi 隨函音釋) in the Pilu Canon 毗盧藏 and examining the bibliographic entries and marginal annotations referencing these catalogues in other editions, the study conducts a philological comparison with sources such as the Qisha 磧砂, Sixi 思溪, and Hongwu Southern Canons 洪武南藏. It identifies specific cases of misattribution, annotation displacement, and the merging of catalogue content without clear attribution. The findings suggest that ambiguity in catalogue entries and textual transmission resulted in instances where the three Zhongjing mulu catalogues were not clearly distinguished in later canons and modern databases. The article contributes to a clearer understanding of the editorial history and philological challenges involved in the formation of the Chinese Buddhist canon. Full article

During the operation of structures, the components and materials from which they are made are exposed to various environmental, technological, and operational impacts. In this context, the use of a modified water-dispersion composition containing finely dispersed fillers with enhanced protective and performance characteristics proves to be effective. This article examines the development of a paint-and-coating composition using hollow glass microspheres and modified diatomite as finely dispersed fillers. The influence of technological factors on the properties of coating materials based on a synthesized acrylic dispersion and fillers—such as modified diatomite and hollow glass microspheres ranging from 20 to 100 μm in size with a bulk density of 0.107–0.252 g/cm³—is analyzed. The optimal formulation of the coating materials was determined to ensure the required coating quality. Experimental results demonstrate the improved strength and hardness of the coating due to the use of acrylic dispersion obtained through an emulsifier-free method and modifiers in the form of finely dispersed fillers. It has been established that the resulting samples also exhibit high adhesion to mineral and metallic substrates, along with excellent corrosion resistance. Moreover, the incorporation of acrylic dispersion contributes to increased elasticity of the coating, resulting in improved resistance to washing and abrasion. The developed protective material can be applied to a variety of surfaces, including walls, ceilings, and roofs of buildings and structures, pipelines, and many other applications. Thus, modified water-dispersion compositions based on synthesized acrylic dispersion showed the following results: resistance to sticking—5, which is the best; chemical resistance and gloss level with standard single-phase acrylic dispersion—no destruction or change in gloss. The adhesion of coatings cured under natural conditions and under the influence of UV radiation was 1 point. The developed formulations for obtaining water-dispersion paint and varnish compositions based on synthesized polymer dispersions, activated diatomite, and hollow glass microspheres, meet all the regulatory requirements for paint and varnish materials in terms of performance, and in terms of economic indicators, the cost of 1 kg of paint is 30% lower than the standard.

This work investigates the relationship between the material properties of wardrobe furniture and visual and tactile emotional responses, with a focus on age-related differences in emotional experiences. This research measured material surface properties (roughness, gloss, and Lab color) and utilized the PAD (pleasure, arousal, dominance) emotion model to assess emotional responses among elderly and younger participants. (1) In the context of tactile emotional experiences, a systematic correlation was observed between surface roughness and the reported levels of pleasure, arousal, and dominance in both elderly and younger participants. Moreover, pleasure demonstrated a systematic correlation with gloss. Rough surfaces were perceived as unpleasant. The elderly participants showed greater emotional dominance when exposed to rough surfaces. (2) In terms of visual–tactile emotional experiences, a responsive relationship was found between pleasure, dominance, and the a* parameter (representing the red and green color channels) in both age groups. However, no systematic correlations were observed between luminance (L*), glossiness, and PAD emotional experiences in either group. A responsive correlation was found between pleasure, dominance, and the b* parameter (representing the yellow and blue color channels) in elderly individuals. Notably, a significant correlation was observed between arousal and roughness in younger individuals. These findings suggest a partial difference in emotional responses across the PAD dimensions between elderly and younger participants. Full article

In the context of optimizing dental care for patients who are elderly, the purpose of this in vitro study was to evaluate the surface gloss (with a micro-area gloss meter) of, surface roughness (with a compact surface roughness measuring instrument) of, and color change (with a dental colorimeter) in two commercially available injectable resin-based composites (Estelite Universal Flow (EUF) and Beautifil Flow Plus F00 (BFP)) as well as two glass–ionomer cements (GC Fuji II LC CAPSULE (FLC) and GC Fuji IX GP EXTRA CAPSULE (FGP)), before and after dental prophylaxis. After 24 h, the surfaces of each specimen were polished at 2500 rpm with a prophy brush (Mersage Brush, Shofu) and one-step prophylaxis paste (Prophy Paste Pro, Directa): under 100 or 300 gf load, and for 10 or 30 s, 4× cycles of cleaning. After mechanical cleaning, conditions were found for a significant reduction in the gloss level (EUF, BFP, or FLC; p < 0.05) and a significant increase in surface roughness (BFP; 300 gf load, 10 s × four cycles of cleaning). Overall, the longer time or higher prophylaxis load tended to decrease the surface gloss. However, the observed change in surface roughness varied between the restorative materials. There was no color change post-prophylaxis. Full article

This article explores the intersections among music composition, religious history and spiritual texts, with their attendant concepts. It focuses on two works with medieval sources—the concert piece Ave generosa (1996) and the chamber opera The Song of Margery Kempe (2008)—which were featured in the online Gallery of the conferences in 2021 and 2022, respectively, of the British and Irish Association for Practical Theology (BIAPT). Through the lenses of semiotics and intertextuality, it explores the ways by which theological concepts and spiritual contexts can be evoked and ‘translated’ into musical sound, both instrumental and vocal. A sampling of the literature on medieval monasticism and St Hildegard of Bingen, whose corpus forms the source of Ave generosa, supports a musical exegesis of its ‘spiritual programme’. In the case of The Song of Margery Kempe, recent scholarship on the text frames examples of the multiplication of meanings provided by dramatisation and musical setting. Art in general and music composition in particular are presented as a commentary, or gloss, on both religious history and enduring spiritual themes, and a different way of thinking about religion and spirituality.

Surface cleaning of plastic materials of historical value can be challenging due to the high risk of inducing detrimental effects and visual alterations. As a result, recent studies have focused on researching new approaches that might reduce the associated hazards and, at the same time, minimize the environmental impact by employing biodegradable and green materials. In this context, the present work investigates the effects and potential suitability of dense carbon dioxide (CO₂) as an alternative and green solvent for cleaning plastic materials of historical value. The results of extensive trials with CO₂ in different phases (supercritical, liquid, and vapor) and under various conditions (pressure, temperature, exposure, and depressurization time) are reported for new, transparent, thick poly(methyl methacrylate) (PMMA) samples. The impact of CO₂ on the weight, the appearance of the samples (dimensions, color, gloss, and surface texture), and modifications to their physicochemical and mechanical properties were monitored via a multi-analytical approach that included optical microscopy, Raman and attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopies, and micro-indentation (Vickers hardness). Results showed that CO₂ induced undesirable and irreversible changes in PMMA samples (i.e., formation of fractures and stress-induced cracking, drastic decrease in the surface hardness of the samples), independent of the conditions used (i.e., temperature, pressure, CO₂ phase, and exposure time).

This paper deals with the effect of heat treatment on the selected physical properties of birch wood. Five stages of heat treatment were used, ranging from 160 °C to 200 °C, in 10 °C increments, having a peak treatment duration of 3 h for each level. Primarily, changes in thermal characteristics, namely conductivity, diffusivity, effusivity, volume heat capacity, changes in colour and gloss parameters, mass loss due to modification and different moisture content in wood under given equilibrium climatic conditions, were monitored. The ISOMET 2114 analyser was used to measure the thermal characteristics. The measurement principle of this analyser is based on the analysis of the thermal response of the analysed material to pulses of heat flow. Measurements of colour, gloss, density and moisture content were carried out according to harmonised EN standards. The aim was to experimentally verify the more or less generally known more positive perception of heat-treated wood, both by touch and sight, i.e., the warmer perception of darker brown shades of wood. In terms of thermal characteristics, the most interesting result is that they gradually decrease with increasing treatment temperature. For example, at the highest treatment temperature of 200 °C, there is a decrease in thermal conductivity by 20.2%, a decrease in volume heat capacity by 15.0%, and a decrease in effusivity by 17.7%. The decrease in thermal conductivity is nearly constant at all treatment levels, specifically at this treatment temperature, by 6.0%. The fact mentioned above is positive in terms of the tactile perception of such treated wood, which can have a positive effect, for example, in furniture with surface application of heat-treated veneers, which are perceived positively by the majority of the human population visually or as a cladding material in saunas. In this context, it has been found that the thermal modification at the above-mentioned treatment temperature of 200 °C results in a decrease in brightness by 44.0%, a decrease in total colour difference by 38.4%, and a decrease in gloss (at an angle of 60°) by 18.2%. The decrease in gloss is only one essential negative aspect that can be addressed by subsequent surface treatment. During the heat treatment, there is also a loss of mass in volume, e.g., at a treatment temperature of 200 °C and subsequent conditioning to an equilibrium moisture content in a conditioning chamber with an air temperature of 20 ± 2 °C and relative humidity of 65 % ± 5%, there was a decrease by 7.9%. In conclusion, the experiments clearly confirmed the hypothesis of a positive perception of heat-treated wood in terms of haptics and aesthetics. Full article

Continuous sign language recognition is a weakly supervised task dealing with the identification of continuous sign gestures from video sequences, without any prior knowledge about the temporal boundaries between consecutive signs. Most of the existing methods focus mainly on the extraction of spatio-temporal visual features without exploiting text or contextual information to further improve the recognition accuracy. Moreover, the ability of deep generative models to effectively model data distribution has not been investigated yet in the field of sign language recognition. To this end, a novel approach for context-aware continuous sign language recognition using a generative adversarial network architecture, named as Sign Language Recognition Generative Adversarial Network (SLRGAN), is introduced. The proposed network architecture consists of a generator that recognizes sign language glosses by extracting spatial and temporal features from video sequences, as well as a discriminator that evaluates the quality of the generator’s predictions by modeling text information at the sentence and gloss levels. The paper also investigates the importance of contextual information on sign language conversations for both Deaf-to-Deaf and Deaf-to-hearing communication. Contextual information, in the form of hidden states extracted from the previous sentence, is fed into the bidirectional long short-term memory module of the generator to improve the recognition accuracy of the network. At the final stage, sign language translation is performed by a transformer network, which converts sign language glosses to natural language text. Our proposed method achieved word error rates of 23.4%, 2.1% and 2.26% on the RWTH-Phoenix-Weather-2014 and the Chinese Sign Language (CSL) and Greek Sign Language (GSL) Signer Independent (SI) datasets, respectively.

Word Sense Disambiguation (WSD) aims to predict the correct sense of a word given its context. This problem is of extreme importance in Arabic, as written words can be highly ambiguous; 43% of diacritized words have multiple interpretations and the percentage increases to 72% for non-diacritized words. Nevertheless, most Arabic written text does not have diacritical marks. Gloss-based WSD methods measure the semantic similarity or the overlap between the context of a target word that needs to be disambiguated and the dictionary definition of that word (gloss of the word). Arabic gloss WSD suffers from a lack of context-gloss datasets. In this paper, we present an Arabic gloss-based WSD technique. We utilize the celebrated Bidirectional Encoder Representation from Transformers (BERT) to build two models that can efficiently perform Arabic WSD. These models can be trained with few training samples since they utilize BERT models that were pretrained on a large Arabic corpus. Our experimental results show that our models outperform two of the most recent gloss-based WSDs when we test them against the same test data used to evaluate our model. Additionally, our model achieves an F1-score of 89% compared to the best-reported F1-score of 85% for knowledge-based Arabic WSD. Another contribution of this paper is introducing a context-gloss benchmark that may help to overcome the lack of a standardized benchmark for Arabic gloss-based WSD. Full article

Word sense disambiguation (WSD) is one of the core problems in natural language processing (NLP), which is to map an ambiguous word to its correct meaning in a specific context. There has been a lively interest in incorporating sense definition (gloss) into neural networks in recent studies, which makes great contribution to improving the performance of WSD. However, disambiguating polysemes of rare senses is still hard. In this paper, while taking gloss into consideration, we further improve the performance of the WSD system from the perspective of semantic representation. We encode the context and sense glosses of the target polysemy independently using encoders with the same structure. To obtain a better presentation in each encoder, we leverage the capsule network to capture different important information contained in multi-head attention. We finally choose the gloss representation closest to the context representation of the target word as its correct sense. We do experiments on English all-words WSD task. Experimental results show that our method achieves good performance, especially having an inspiring effect on disambiguating words of rare senses. Full article

This paper focuses on the domain-specific senses of words and proposes a method for detecting predominant sense depending on each domain. Our Domain-Specific Senses (DSS) model is an unsupervised manner and detects predominant senses in each domain. We apply a simple Markov Random Walk (MRW) model to ranking senses for each domain. It decides the importance of a sense within a graph by using the similarity of senses. The similarity of senses is obtained by using distributional representations of words from gloss texts in the thesaurus. It can capture large semantic context and thus does not require manual annotation of sense-tagged data. We used the Reuters corpus and the WordNet in the experiments. We applied the results of domain-specific senses to text classification and examined how DSS affects the overall performance of the text classification task. We compared our DSS model with one of the word sense disambiguation techniques (WSD), Context2vec, and the results demonstrate our domain-specific sense approach gains 0.053 F1 improvement on average over the WSD approach.

This paper focuses on Charlotte Wood’s 2015 dystopian novel The Natural Way of Things. Set in an unnamed place in the Australian outback, it recounts the story of 10 girls in their late teens and early twenties who are kept prisoners by a mysterious corporate organisation for their sexual involvement with an array of powerful men. The novel’s title invites two main readings: the first, and perhaps more obvious, along gender lines; and the second, which will provide the backbone to my analysis, within the framework of the natural world, the animal kingdom in particular. The Natural Way of Things has been described as a study in contemporary misogyny and the workings of patriarchy. The ingrained sexism of society—the insidious, normalised violence against females, often blamed on them, glossing over male responsibility—is undoubtedly the central topic of Wood’s work. Without losing sight of gender issues, my approach to Wood’s novel is inspired by Rosi Braidotti’s posthuman theories on the continuum nature–culture and the primacy of zoe—“the non-human, vital force of life”—over bios, or life as “the prerogative of Anthropos” (Rosi Braidotti). According to Braidotti, the current challenges to anthropocentrism question the distinction between these two forms of life, highlighting instead the seamless connection between the natural world and culture and favouring a consideration of the subject as embodied, nomadic and relational. My reading of The Natural Way of Things in light of Braidotti’s insights will be supplemented by an analysis of the novel in the context of transmodernity, both a period term and a distinct way of being in the world theorised by critics such as Rosa M. Rodríguez Magda and Marc Luyckx, who emphasise the relational, interdependent nature of contemporary times from a more human-centred perspective. The Natural Way of Things is also a story of female empowerment. This is especially the case with Yolanda Kovacs and Verla Learmont, the two protagonist women, who step out of their roles as victims and stand up to their guards. My analysis of the novel will revolve around these two characters and their different reactions to confinement and degradation. I conclude that although a more zoe-centred conception of the human subject that acknowledges the human–animal continuum should definitely be welcomed, literally “becoming animal”, as Yolanda does, deprives one of meaningful human relationality, embodied in the novel in Verla’s memories of her caring, empathic relationship with her father.

The article takes up the biblical category of “headship,” one of the “third rails” for Christians in a context dominated by the limited conceptions of equality, especially those assumed by “second wave” and “difference” feminism, viz., that of interchangeable sameness and unbridgeable difference. Headship is easily dismissed as an instance of (bad) cultural influence that spoiled Christianity’s egalitarian beginnings. Less radically, headship is simply avoided, or glossed over with apologetic caveats. Headship is an embarrassment, because it suggests not only exclusive differences—the “head” is not the “body”—but an order between them. Head and body are “subject to each other” in distinct and coordinated ways. In what follows, the author claims that headship is not only not an affront to equality, but its very condition between subjects who belong to each other in a generous relation of reciprocal and fruitful unity and distinction. Moreover, it is the expression of the novelty of Christianity, regarding first of all the nature of God in whom there is an original Head, and a “positive other,” without any hint of subordinationism (inequality). On the contrary, the Father is never absolute, but always already determined by the Son. This original headship then informs the Christian conception of the world, its positivity, even to the point that it can give something to God. Finally, it informs the this-worldly headships (Christ–Church and husband–wife). There, headship counters the status quo, by countering the “body’s” default immanentistic “certainty” about her exclusive life-giving power, enjoining her to acknowledge a transcendent source. It restores equality to the head. For the “head,” it counters the false absolutist image of God, while enjoining him to “radiate” something of which he is first “subject,” to “be involved with,” and determined by, the woman, as a positive other. It restores equality to the body. In sum, the article urges us to turn towards the deepest resources of Christianity, to find therein a more fruitful equality. Full article

The amount of plastics used globally today exceeds a million tonnes annually, with an alarming annual growth. The final result is that plastic packaging is thrown into the environment, and the problem of waste is increasing every year. A real alternative is the use bio-based polymer packaging materials. Research carried out in the laboratory context and products tested at the industrial level have confirmed the success of replacing plastic-based packaging with new, edible or completely biodegradable foils. Of the polysaccharides used to obtain edible materials, sodium alginate has the ability to form films with certain specific properties: resistance, gloss, flexibility, water solubility, low permeability to O₂ and vapors, and tasteless or odorless. Initially used as coatings for perishable or cut fresh fruits and vegetables, these sodium alginate materials can be applied to a wide range of foods, especially in the meat industry. Used to cover meat products, sodium alginate films prevent mass loss and degradation of color and texture. The addition of essential oils prevents microbial contamination with Escherichia coli, Salmonella enterica, Listeria monocytogenes, or Botrytis cinerea. The obtained results promote the substitution of plastic packaging with natural materials based on biopolymers and, implicitly, of sodium alginate, with or without other natural additions. These natural materials have become the packaging of the future. Full article
