Los feminismos han colocado en el debate público la identidad de las mujeres y la relación con sus diferentes espacios relacionales que atraviesan lo personal y estructural. Esto también afecta lo cristiano, situación que ha permitido que sean visibilizadas las mujeres desde lo que ha sido llamado una hermenéutica de la sospecha. Así se ha podido reconocer al kyriarcado como una estructura sociocultural alienante y descubrir mujeres que no han sido mencionadas desde el cristianismo primitivo hasta nuestra época. En esa línea de pensamiento también se tomará en cuenta una perspectiva ética latinoamericana que cuestione no solo la praxis social cristiana, sino que busca considerar los elementos que la han fortalecido. En ese sentido, desde una perspectiva genealógica, una postura ética antipatriarcal toma en serio la crítica de los feminismos y asume la responsabilidad desde los cuerpos masculinos y a ellos se dirige. Esto implica posicionarse ante los modos de hacer teología y los elementos narrativos que han sido ocupados para justificarse, para así cuestionar la religión patriarcal y proponer un cambio de visión que contemple lo diverso como una posibilidad relacional en horizontalidad y una participación activa que exponga en nuestros actos la Divinidad en la que creemos.
Feminist movements have brought the identity of women and their relationships with various personal and structural spheres into public discussion. This has also influenced Christianity, a situation that has enabled women to be recognized through what is called a hermeneutics of suspicion. This approach has helped identify kyriarchy—an alienating sociocultural structure—and has brought to light the neglect of women from early Christianity to the present day. This paper also incorporates a Latin American ethical perspective that not only questions Christian social practices but also seeks to understand the elements that have reinforced them. From a genealogical viewpoint, an anti-patriarchal ethical approach takes feminist critiques seriously, assumes responsibility for them from a male perspective, and addresses men directly. This means challenging traditional theological methods and the narratives used to justify them. The goal is to question patriarchal religion and propose a shift in vision that sees diversity as a relational possibility, promoting horizontal relationships and active participation that reveal the Divine in our actions.

Light control in generated images is a difficult task, posing specific challenges, spanning over the entire image and frequency spectrum. Most approaches tackle this problem by training on extensive yet domain-specific datasets, limiting the inherent generalization and applicability of the foundational backbones used. Instead, PractiLight is a practical approach, effectively leveraging foundational understanding of recent generative models for the task. Our key insight is that lighting relationships in an image are similar in nature to token interaction in self-attention layers, and hence are best represented there. Based on this and other analyses regarding the importance of early diffusion iterations, PractiLight trains a lightweight LoRA regressor to produce the direct irradiance map for a given image, using a small set of training images. We then employ this regressor to incorporate the desired lighting into the generation process of another image using Classifier Guidance. This careful design generalizes well to diverse conditions and image domains. We demonstrate state-of-the-art performance in terms of quality and control with proven parameter and data efficiency compared to leading works over a wide variety of scenes types. We hope this work affirms that image lighting can feasibly be controlled by tapping into foundational knowledge, enabling practical and general relighting.
Alexander Andreevich Andrianov was a remarkable personality in Russian physics during the last decades. A member of th prestigious school of theoretical physics in Saint Petersburg, he made relevant contributions to a number of topics along his life. His activity ran in parallel with profound changes in his home country and the international arena. He was very much involved in this series of conferences, being the host of the 2014 edition in Saint Petersburg. In this presentation made at the XVI Conference on Quark Confinement and Hadron Spectrum I will provide a vision -- necessarily personal -- of his life and his activities and how these influenced many of us.

We present a strong theoretical foundation that frames a well-defined family of outer-totalistic network automaton models as a topological generalisation of binary outer-totalistic cellular automata, of which the Game of Life is one notable particular case. These "Life-like network automata" are quantitatively described by expressing their genotype (the mean field curve and Derrida curve) and phenotype (the evolution of the state and defect averages). After demonstrating that the genotype and phenotype are correlated, we illustrate the utility of these essential metrics by tackling the firing squad synchronisation problem in a bottom-up fashion, with results that exceed a 90% success rate.
Life demonstrates remarkable homochirality of its major building blocks: nucleic acids, amino acids, sugars, and phospholipids. We propose a mechanism that places the root of life homochirality in the formation of phospholipid bilayer vesicles (liposomes). These liposomes are formed at the water-air interface from Langmuir layers and contain ribose, presumably delivered to Early Earth by carbonaceous meteorites. Although the extraterrestrial ribose was initially racemic, life is homochiral, based on D-ribose and its derivatives. The phospholipid membrane high permeability to D-ribose, combined with the ribose interaction with the bilayer charged phosphate groups, leads to ribose phosphorylation, forming D-ribose-5-phosphate. Once inside, the D-ribose-5-phosphate molecules cannot cross the membrane. The catalytic action of Fe (3+ions) greatly enhances the phosphorylation rate. Overall, this process is enantioselective, substantially favoring the buildup of D-ribose over L-ribose. Through liposome fusion, fission, and self-replication, this eventually leads to the Darwinian evolution of these structures and to the conversion of D-ribose-5-phosphate into complex functional molecules, such as ribozymes and RNA, and eventually into DNA, all of which inherit D-ribose chirality.
AbstractCan racial primes influence support for public expressions of religion? While a growing body of research demonstrates correlations between racial attitudes and support for public religion among White Americans, experimental tests of subconscious connections between the two concepts have been lacking. We utilize a novel survey experiment to prime racial considerations, and we find that Black racial primes raise support for Christian nationalism and civil religion among White Americans, compared to White racial primes. Moreover, our analysis indicates that these effects are attributable to racial animus, namely the evaluation that Black Americans are not prototypical members of the national community. The findings suggest that the preference for a Christian/religious America and a White America are subconsciously interwoven for many White Americans, providing the first experimental evidence, to our knowledge, of this relationship.
The topic of academic integrity and ethics and culture of behavior is recognized as relevant in various communities and the scientific community. Homo digital, possessing a high level of critical thinking, should become the model of personality in the new paradigm of education. In the article, the authors analyze the philosophical aspects of Paulo Freire's critical pedagogy through the prism of academic integrity in the context of the modern development of the philosophy of education. They conclude that education is a means of liberating a person, and academic integrity is a way to achieve the same goal. Academic integrity is indirectly supported by the correct choice of communication methods, as well as procedures for creating new knowledge and the image of the world, which is personalized by a specific student. Various practices involved in the processes of perception allow a multidimensional understanding of the realities of the world. The authors emphasize that the concept of education, developed by the Brazilian pedagogue and philosopher F. Freire, involves a highly personal perception of the real world and educational content through a critical approach, which is supported by comparing the new knowledge acquired by the student with personal life experience.
Living organisms have some common structures, chemical reactions and molecular structures. The organisms consist of cells with cell division, they have homochirality of protein and carbohydrate units, and metabolism, and genetics, and they are mortal. The molecular structures and chemical reactions underlying these features are common from the simplest bacteria to human beings. The origin of life is evolutionary with the emergence of a network of spontaneous biochemical reactions, and the evolution has taken place over a very long time. The evolution contains, however some "landmarks" and bottlenecks, which in a revolutionary manner directed the evolution, and the article tries to establish the order of these events. The article advocates that a possible order in the emergence of life is that the first milestone in prebiotic evolution is at the emergence of homochirality in proteins. The homochirality of peptides is, however, with instability and racemization which causes aging of the peptides and mortality. The metabolism and genetics are established through homochiral enzymes in the Earth's crust for $\approx$ 4 Gyr ago. Finally, the cells with cell division are established in the Hot Springs environment at the interface between the crust and the Hadean Ocean.
Asphalt concrete's (AC) durability and maintenance demands are strongly influenced by its fatigue life. Traditional methods for determining this characteristic are both resource-intensive and time-consuming. This study employs artificial neural networks (ANNs) to predict AC fatigue life, focusing on the impact of strain level, binder content, and air-void content. Leveraging a substantial dataset, we tailored our models to effectively handle the wide range of fatigue life data, typically represented on a logarithmic scale. The mean square logarithmic error was utilized as the loss function to enhance prediction accuracy across all levels of fatigue life. Through comparative analysis of various hyperparameters, we developed a machine-learning model that captures the complex relationships within the data. Our findings demonstrate that higher binder content significantly enhances fatigue life, while the influence of air-void content is more variable, depending on binder levels. Most importantly, this study provides insights into the intricacies of using ANNs for modeling, showcasing their potential utility with larger datasets. The codes developed and the data used in this study are provided as open source on a GitHub repository, with a link included in the paper for full access.

Why are life trajectories difficult to predict? We investigated this question through in-depth qualitative interviews with 40 families sampled from a multi-decade longitudinal study. Our sampling and interviewing process were informed by the earlier efforts of hundreds of researchers to predict life outcomes for participants in this study. The qualitative evidence we uncovered in these interviews combined with a well-known mathematical decomposition of prediction error helps us identify some origins of unpredictability and create a new conceptual framework. Our specific evidence and our more general framework suggest that unpredictability should be expected in many life trajectory prediction tasks, even in the presence of complex algorithms and large datasets. Our work also provides a foundation for future empirical and theoretical work on unpredictability in human lives.
Digital life, a form of life generated by computer programs or artificial intelligence systems, it possesses self-awareness, thinking abilities, emotions, and subjective consciousness. Achieving it involves complex neural networks, multi-modal sensory integration [1, 2], feedback mechanisms, and self-referential processing [3]. Injecting prior knowledge into digital life structures is a critical step. It guides digital entities' understanding of the world, decision-making, and interactions. We can customize and personalize digital life, it includes adjusting intelligence levels, character settings, personality traits, and behavioral characteristics. Virtual environments facilitate efficient and controlled development, allowing user interaction, observation, and active participation in digital life's growth. Researchers benefit from controlled experiments, driving technological advancements. The fusion of digital life into the real world offers exciting possibilities for human-digital entity collaboration and coexistence.
Viewed as one of the grandest questions in modern science, understanding fundamental physical constants has been discussed in high-energy particle physics, astronomy and cosmology. Here, I review how condensed matter and liquid physics gives new insights into fundamental constants and their tuning. This is based on two observations: first, cellular life and the existence of observers depend on viscosity and diffusion. Second, the lower bound on viscosity and upper bound on diffusion are set by fundamental constants, and I briefly review this result and related recent developments in liquid physics. I will subsequently show that bounds on viscosity, diffusion and the newly introduced fundamental velocity gradient in a biochemical machine can all be varied while keeping the fine-structure constant and the proton-to-electron mass ratio intact. This implies that it is possible to produce heavy elements in stars but have a viscous planet where all liquids have very high viscosity (for example that of tar or higher) and where life may not exist. Knowing the range of bio-friendly viscosity and diffusion, we will be able to calculate the range of fundamental constants which favor cellular life and observers and compare this tuning with that discussed in high-energy physics previously. This invites an inter-disciplinary research between condensed matter physics and life sciences, and I formulate several questions that life science can address. I finish with a conjecture of multiple tuning and an evolutionary mechanism.
Digital libraries provide an easy and convenient source of data for journalistic academic research. In this paper, the author answers the question of whether the most well-known socio-political Polish press titles published between 1918 and 1939 are available online and to what extent they are fully digitised and accessible in digital libraries. Through media content analysis and the press content analysis methods of Walery Pisarek, all the digital resources available for an ordinary Internet user were browsed. The main role of the analysis was to establish which journals and periodicals were published weekly and as daily newspapers. Also, the nature and political leanings of press publications were taken into consideration (each press title was usually associated with a particular party). At the same time, the texts were profiled as regional, national, Catholic, etc. Finally, an attempt to develop a typology of the given titles is made.
Complex systems fail. I argue that failures can be a blueprint characterizing living organisms and biological intelligence, a control mechanism to increase complexity in evolutionary simulations, and an alternative to classical fitness optimization. Imitating biological successes in Artificial Life and Artificial Intelligence can be misleading; imitating failures offers a path towards understanding and emulating life it in artificial systems.
We describe the principles of counterfactual thinking in providing more precise definitions of causal effects and some of the implications of this work for the way in which causal questions in life course research are framed and evidence evaluated. Terminology is explained and examples of common life course analyses are discussed that focus on the timing of exposures, the mediation of their effects, observed and unobserved confounders, and measurement error. The examples are illustrated by analyses using singleton and twin cohort data.
The RCSA’s ‘missional standstill’ after 150 years: While the Reformed Churches in South Africa (hereafter RCSA) is looking back gratefully over the past 150 years, it is also compelled to reflect on its disparaging existence of the past 25 years. Several RCSA Synods have for some time, been paying close attention to comprehensive deputy reports on ‘falling membership numbers’. They also have made incisive decisions on, among other things, a ‘Conversion Strategy’, and recently on a ‘Church Growth Ministry’. The same reduction in numbers that degraded the Christian church within the Western culture to a post-Christendom reality, has also been identified in the RCSA. This article looks back in history and focuses, among other things, on the spiritual legacy of the RCSA. This legacy, from the historical and theological development of post-Reformational theology, and also from the Netherlands, influenced the church life of the RCSA in Southern Africa. This reflection is essential to really understand the current challenges of the RCSA in order to refocus its future biblical response to God’s call. It is clear that the RCSA will have to reform missiologically in order to face the new post-Christendom reality of our globalising world.

We propose a new class of semiparametric regression models of mean residual life for censored outcome data. The models, which enable us to estimate the expected remaining survival time and generalize commonly used mean residual life models, also conduct covariate dimension reduction. Using the geometric approaches in semiparametrics literature and the martingale properties with survival data, we propose a flexible inference procedure that relaxes the parametric assumptions on the dependence of mean residual life on covariates and how long a patient has lived. We show that the estimators for the covariate effects are root-$n$ consistent, asymptotically normal, and semiparametrically efficient. With the unspecified mean residual life function, we provide a nonparametric estimator for predicting the residual life of a given subject, and establish the root-$n$ consistency and asymptotic normality for this estimator. Numerical experiments are conducted to illustrate the feasibility of the proposed estimators. We apply the method to analyze a national kidney transplantation dataset to further demonstrate the utility of the work.

Can multicellular life be distinguished from single cellular life on an exoplanet? We hypothesize that abundant upright photosynthetic multicellular life (trees) will cast shadows at high sun angles that will distinguish them from single cellular life and test this using Earth as an exoplanet. We first test the concept using Unmanned Arial Vehicles (UAVs) at a replica moon landing site near Flagstaff, Arizona and show trees have both a distinctive reflectance signature (red edge) and geometric signature (shadows at high sun angles) that can distinguish them from replica moon craters. Next, we calculate reflectance signatures for Earth at several phase angles with POLDER (Polarization and Directionality of Earth's reflectance) satellite directional reflectance measurements and then reduce Earth to a single pixel. We compare Earth to other planetary bodies (Mars, the Moon, Venus, and Uranus) and hypothesize that Earths directional reflectance will be between strongly backscattering rocky bodies with no weathering (like Mars and the Moon) and cloudy bodies with more isotropic scattering (like Venus and Uranus). Our modelling results put Earth in line with strongly backscattering Mars, while our empirical results put Earth in line with more isotropic scattering Venus. We identify potential weaknesses in both the modeled and empirical results and suggest additional steps to determine whether this technique could distinguish upright multicellular life on exoplanets.
African Traditional Religion (ATR) represents a primal worldview that encapsulates a certain culturally-innate sense of the world of transcendence and involves belief in a sacramental ‘enchanted’ universe in which the physical is indicative of spiritual realities, in contrast to western Christianity, that to a certain extent abandoned belief in malevolent powers. The assumption is that Africans live in an ‘intentional world’ where nothing happens by chance; all events have spiritual causes. Negative events can be resisted by imprecatory prayers and curses. Sacred and secular realities are inseparable. For this reason, it is argued that pneumatic Christianity is close to the grain of African culture and its worldview resonates with the indigenous worldview. In this article, the African background of Pentecostal theology is investigated. By operating within a worldview that allows ample space for the invisible world determining what happens in the visible world, African Pentecostalism was endeared to Africans. For Africans, what happens on earth is directly interrelated with what happens in the dimension of the spiritual, agreeing with the cosmic principalities and powers that provide the mystical causality of a worldview found in the New Testament. The African Pentecostal narrative is concerned with the solution of personal and societal problems that is interpreted in terms of the African view of rulers, authorities, evil powers, cosmic powers, and spiritual forces in the heavenly realm that focuses on how the spirit world impinges on the visible world to hinder or foster human flourishing. Pentecostalism’s pneumatic spirituality is discussed from a critical theological perspective.

Given a directed graph and a source vertex, the fully dynamic single-source reachability problem is to maintain the set of vertices that are reachable from the given vertex, subject to edge deletions and insertions. It is one of the most fundamental problems on graphs and appears directly or indirectly in many and varied applications. While there has been theoretical work on this problem, showing both linear conditional lower bounds for the fully dynamic problem and insertions-only and deletions-only upper bounds beating these conditional lower bounds, there has been no experimental study that compares the performance of fully dynamic reachability algorithms in practice. Previous experimental studies in this area concentrated only on the more general all-pairs reachability or transitive closure problem and did not use real-world dynamic graphs. In this paper, we bridge this gap by empirically studying an extensive set of algorithms for the single-source reachability problem in the fully dynamic setting. In particular, we design several fully dynamic variants of well-known approaches to obtain and maintain reachability information with respect to a distinguished source. Moreover, we extend the existing insertions-only or deletions-only upper bounds into fully dynamic algorithms. Even though the worst-case time per operation of all the fully dynamic algorithms we evaluate is at least linear in the number of edges in the graph (as is to be expected given the conditional lower bounds) we show in our extensive experimental evaluation that their performance differs greatly, both on generated as well as on real-world instances.
