This study analyzes the strategic and institutional frameworks that precede the formulation of trade agreements, with a focus on the European Union’s external action and its link to the Sustainable Development Goals. Based on a documentary research design, this study examines official documents from the EU and the United Nations, as well as the academic literature indexed in Scopus and Web of Science. The methodological process involved four phases: systematic search, selection and classification, inductive content coding, and interpretative analysis. Through this process, this study identifies discursive patterns, normative tensions, and policy orientations that reveal the EU’s evolving approach to sustainable trade governance. The findings highlight the existence of a growing institutional alignment between trade policy and sustainable development frameworks, yet also expose persistent gaps in coherence and implementation. This article contributes to the academic debate by offering a critical and structured analytical lens to understand how trade agreements are politically and institutionally prefigured before their negotiation phase.

This paper addresses the longstanding tension between reason and revelation in Islamic religious epistemology, with a focus on the thought of Ibn Taymiyyah (d. 728/1328). It aims to reassess his critique of philosophical theology (falsafa and kalām) and explore his constructive alternative to rationalist metaphysics. The study adopts a descriptive–analytical methodology, combining close textual reading of Darʾ Taʿāruḍ al-ʿAql wa al-Naql and Naqd al-Manṭiq with conceptual analysis informed by contemporary religious epistemology and philosophy of religion. The findings reveal that Ibn Taymiyyah advances a triadic epistemological model centered on revelation (naql), reason (ʿaql), and innate disposition (fiṭrah). He refutes the autonomy of reason, redefines logic as a tool rather than a judge, and repositions fiṭrah as an intuitive foundation for belief. His approach emphasizes the harmony of sound reason with authentic revelation and challenges the epistemic assumptions of speculative theology. By presenting a comparative table of rationalist and Taymiyyan epistemologies, the study demonstrates how Ibn Taymiyyah’s framework anticipates key themes in Reformed Epistemology and the cognitive science of religion. The conclusions suggest that his vision offers a coherent, theocentric paradigm for religious knowledge that is highly relevant to the contemporary philosophy of religion and Islamic theology.

The rapid growth of digital platforms has fundamentally reshaped network and viral marketing, profoundly transforming how information spreads across social networks and influences consumer behavior. This comprehensive review synthesizes theoretical, computational, and ethical perspectives into an integrated narrative, providing novel insights into the mechanisms driving information diffusion within contemporary interactive marketing. By integrating foundational concepts from social network theory, advanced graph models, and behavioral dynamics, the paper demonstrates how the interplay between network structures, influencer behaviors, and AI-driven algorithms significantly redefines traditional marketing paradigms. A distinctive theoretical contribution of this study lies in its innovative combination of Big Data analytics with AI-based predictive modeling, explicitly revealing how real-time algorithmic personalization not only enhances marketing effectiveness but also creates new ethical tensions surrounding misinformation, algorithmic bias, and consumer vulnerability. Addressing recent calls for greater theoretical originality and narrative coherence in interactive marketing research, this review explicitly highlights how these insights resolve critical theoretical puzzles and clarify contemporary ethical dilemmas. Additionally, the paper identifies emerging trends—including Web3 marketing, decentralized platforms, and neuroscience-driven targeting—offering clear future research directions. Through its integrative, narrative-driven framework, this study significantly advances interactive marketing theory, providing essential guidance for scholars and practitioners navigating the evolving complexities of digital influence.

This study aims to reduce pores, cracks, and other defects on the surface of laser powder bed fusion (LPBF)-fabricated 18Ni300 steel and improve its surface quality. Remelting was carried out on the surface with an argon arc as the heat source. Then, the surface layer was characterized using SEM, EDS, XRD, EBSD, and hardness testing. The results showed the following: When the pulse current $I$ increased from 16 A to 20 A, the surface hardness of LPBF 18Ni300 increased due to a decrease in defects and an increase in the martensite phase. The driving forces of convection in the molten pool (such as buoyancy, Lorentz magnetic force, surface tension, and plasma flow force) rose with an increase in current. When the current $I$ exceeded 20 A, the convection became more intense, making it easier for gas to be entrained into the melt pool, forming pores and introducing new defects, resulting in a decrease in surface hardness. The primary factors affecting the hardness of LPBF 18Ni300 after surface argon arc remelting were pore (defect) weakening and phase transformation strengthening, while the secondary factors included grain refinement strengthening and texture strengthening. The solidification mode of the remelted layer was: L → A → M + A′. The phase transition mode of the heat-affected zone was: M + A′ → A_reverse → M_temper. Compared with the base material and heat-affected zone, the grains in the remelted layer formed a stronger <001> texture with a larger average size (2.51 μm) and a lower misorientation angle. The content of the residual austenite A′ was relatively high in the remelted layer. It was distributed in the form of strips along grain boundaries, and it always maintained a shear–coherent relationship with martensite. Full article

This article reports on the first qualitative phase of an exploratory sequential mixed method (ESMM) research design focusing on EFL pronunciation instruction in Spanish primary schools. Firstly, it presents an analysis of the National Curriculum in light of recent policy changes and adaptations across seventeen Autonomous Communities (AACC) to assess coherence and the scaffolding of contents. Secondly, based on results from Focus Groups with eight instructors from five different schools and two different AACC, teachers’ perceptions on EFL pronunciation teaching in the current curriculum change are examined according to two main strands, i.e., Curriculum Design and Development and Teacher Professional Development. The results reveal asymmetries in Curriculum Contents regarding specificity and teaching methodologies, as well as some conceptual inconsistencies and dispositions that seem to be leading to overregulation, particularly in relation to increased measures of public accountability. These appear to be heightening tensions that are causing a mismatch between the intended Curriculum and the instructor-experienced curriculum. Another key observation is that, in this scenario, the positive beliefs and attitudes of primary school teachers towards EFL pronunciation are insufficient for optimal teaching. Intervention measures and innovations are suggested to improve the situation, which may be extrapolated to other similar EFL contexts. Full article

IPCC climate forecast models, applicable to the Maghreb countries (Morocco, Algeria, and Tunisia), predict a decrease in atmospheric precipitation, greater variability, and an increase in aridity. In recent years, the entire region has been experiencing unprecedented climate upheavals. Climatic droughts have become increasingly severe and recurrent (drastically reducing water stocks). We are also witnessing a remarkable increase in temperatures and a greater frequency of heat waves. Faced with these new provisions, this territory (long considered an area of water stress) is now subject to very strong tensions, which have led to a greater demand for water and a decrease in supply. To understand the intensity of this “climate–water” crisis, we propose an analysis of this priority issue based on the evolution of precipitation over more than half a century of records. To determine precipitation trends and define rainfall cycles in these three countries, the graphical chronological method of information processing (MGCTI) of the “BERTIN Matrix” type is used. Annual precipitation totals from 29 stations were used for the MGCTI (chronological graphic method of information processing) for the period 1970–2023. These data come from the national meteorological networks of the National Meteorological Office (ONM) for Algeria, National Institute of Meteorology (NIM) for Tunisia, and National Directorate of Meteorology (DMN) for Morocco, and the from the websites of the National Climatic Data Center (NCDC) and “TuTiempo Network”. Monthly pluviometric totals from three stations, Dar El Beida (Algeria), Casablanca (Morocco), and Tunis (Tunisia), as well as the monthly NAO (North Atlantic Oscillation) and MOI (Mediterranean Oscillation Index) were used for the wavelet coherence method for the period 1970–2022. Data analysis shows that the entire region is subject to four extreme precipitation cycles (dry and wet). The last dry period was remarkably intense and led to a sharp increase in water stress throughout the region. An analysis of monthly precipitation from three stations (Casablanca, Dar El Beida, and Tunis) using the wavelet coherence method also highlighted a close relationship with the “NAO” and “MOI” circulation.

After criticizing the three traditional proofs of divine existence in the first Critique, Kant fills this void with an apologetic argument based on his practical philosophy. However, this moral–religious project has long been charged with various inconsistencies, particularly regarding the tension between the demand for moral perfection and human limitation. There is even some indication that he becomes aware of these issues, as he later moves away from the vision of endless moral progress that holds his original project together. However, this revision does not resolve all the tensions, as the question of how imperfect humans can be well-pleasing to God remains. I argue that this predicament is a difficult-to-avoid feature of his project given how it interacts with his religious context of Lutheran Christianity. This is because he incorporates some of its elements (particularly its uncompromising moral standard) virtually intact while radically altering others (such as vicarious atonement and imputation of alien righteousness). However, this procedure undermines the coherence of the tradition he inherits because the elements he fully incorporates are meant to lead to the traditional doctrines he leaves behind. I conclude by reflecting on how theists who are sympathetic to Kant should lead his moral–religious project out of its current precarious predicament. Full article

We have compared the biomechanical properties of human and porcine corneas using vibrational optical coherence tomography (VOCT). The elastic modulus of the cornea has been previously reported in the literature to vary from about several kPa to more than several GPa based on the results of different techniques. In addition, the formation of corneal cones near the central cornea in keratoconus has been observed in the clinic. Measurements of the resonant frequency and morphology of human and porcine corneas were used to evaluate the role of the limbus in corneal stabilization, the effect of Bowman’s layer, and the effect of collagen content on the low-strain corneal biomechanics. The results of these studies indicate that limbus stability plays an important anatomic role in preventing folding, corneal slippage, and cone formation. Machine learning studies of both human and porcine corneas indicate that Bowman’s membrane, like that of the collagen fibrils found in the anterior corneal stroma, contributes to the 110–120 Hz resonant frequency peak. Finite element and SOLIDWORKS models of normal and keratoconus corneas suggest that the deformation of the cornea is the highest at the central zone and is higher in keratoconus corneas compared to normal controls. VOCT results suggest that although collagen fibril slippage occurs first at the limbus, cone formation in keratoconus occurs centrally/paracentrally, where stress concentration and deformation due to intraocular forces are the highest. Cone formation occurs at the points of maximum curvature. Results of these studies indicate the elastic modulus of cornea fibrillar collagen dictates the corneal elastic modulus at low strains. These results suggest that tension in the cornea at the limbus results in deformation into the low modulus region of the J-shaped stress–strain curve, resulting in an in vivo strain of less than about 10%. We propose that tension in the cornea provides a baseline force that regulates corneal epithelial regeneration as well as corneal lamellae composition and matrix turnover. Full article

This paper explores the nature of Cartesian persons in relation to contemporary Social Trinitarian doctrines. We critically engage with three prominent models of the Social Trinity—those of William Lane Craig, Keith Yandell, and William Hasker—and examine how each defines the concept of personhood. Our analysis identifies the presence of a Cartesian notion of personhood (broadly defined) across all three models, though we argue that each presents unique challenges. Building on these critiques, we advance an alternative understanding of the Social Trinity that incorporates a distinct interpretation of Cartesian persons. Our proposal seeks to resolve tensions within current models and offer a more coherent account of Trinitarian personhood. Full article

Background: The global food system faces growing pressure from population growth, climate change, wealth inequity, geo-political instability, and damage to the ecosystems on which our food supply depends. Fragmentation of the priorities and needs of food system stakeholders—citizens, food producers, food industries, governments—compounds the problem, with competing or misaligned interests increasing the risk of failure to adequately meet the needs of those that form, and are served, by the food system. Growing consensus on the need for transformative system level change to address the problems facing the food system is yet to be significantly reflected in strategic action. Methods: The national food strategy of the UK is offered as an exemplar to discuss the need to promote more coherent and ambitious visions of transformative change that acknowledge the complexity of the food system as a whole. We draw upon cross-sectoral experience to distil the needs, priorities, and key food system tensions that must be acknowledged to promote transformative systems change that equitably delivers healthy sustainable diets, contributes to a resilient global food system, and protects the environment. Results: Greater coherence, ambition, and consideration of the food system as a whole are needed if a UK national food strategy is to contribute to significant transformative change. Conclusions: To promote this, we advocate for (1) a food system digital twin to model and test potential food system interventions or legislation; (2) a citizens’ forum to inform and co-develop a cohesive national food strategy; and (3) increased cohesion and integration of food system governance within government to drive a coherent, ambitious national food strategy.

In a Wilberforce pendulum, two mechanical oscillators are coupled: one pertains to the longitudinal (tension) motion and the other to the rotational (twisting) motion. It is shown that the longitudinal magnetic moment of circular currents, and similarly the magnetic moment of a spin-chain, can exhibit a Wilberforce-like vibration. The longitudinal oscillation is related to the Langevin diamagnetism, while the twisting motion is superimposed on the magnetic moment and spin precession. The calculations show that the coupling term is nonlinear in this (longitudinal) vibrating and (magnetic moment) precession system. By increasing the strength of the coupling we arrive at a spectrum, where further vibrational modes can be associated with the rotation of the precession. This means that the extent of the change in coherence can be demonstrated. Since the coupling strength can be different due to local effects, this can be an important factor from the point of view of signal propagation and in preserving signal shapes. The amount specifying the dissipation is introduced to express the degree of deviation. A relationship exists between the parameter characteristic of the coupling strength and how its quantity influences decoherence and dissipation. Full article

How do individuals find assurance of their personal standing before God? This article discusses the way different traditions of the Christian faith tried to answer the question—some leaving room for doubt in the process and others demanding absolute certainty from the believer. All fellowships experienced some problems with the issue due to the very nature of the question. Assurance required a reflexive act that turned the eyes of the believer away from the good things of God and the promises of the gospel toward an inspection of one’s inner man and motives that were difficult to discern. Those fellowships that emphasized a human condition in the process of salvation or assurance often struggled with their depravity before God and unworthiness to claim the promises of divine grace. This paper particularly focuses upon the struggles of the so-called Calvinists, who were more enamored with the question than the other fellowships and had difficulty developing a coherent or definitive answer, caught as they were between tensions in their theology, between the Christocentric vision of John Calvin that led toward assurance and the synergistic tendences of Theodore Beza and Heinrich Bullinger that led toward doubt. The paper provides some criticism of their theology but sympathizes with their struggle and finds faith and doubt inevitable parts of the Christian life here on earth. Full article

In this paper, I focus on the puzzling ending of the apostolic letter in Acts 15 in which the addressees are told that if they hold to four “essential” prohibitions, they will “do well” (εὖ πράξετε, v. 29). The question as to how, exactly, can destabilise some understandings of the decree, with alternative translations creating different problems, and particularly so where theological commitments are at play. Following Danker’s call for greater attention to this phrase, I undertake a fresh, stratified survey of Greek usage across corpora ranging from the arguably less to the more proximate and bring this into dialogue with the senses given in various literary and social approaches to the decree involving epistolary rhetoric, reciprocity theory, and intertextuality. This reveals how purely linguistic data can stand in tension with compositional arguments in different ways and require a more complex arbitration between possibility, likelihood and coherence when both lexical- and discourse-level constraints are applied. Whilst not solving the problem of the decree outright, observing the impacts of different readings of εὖ πράξετε on the delicate balances involved presses some oblique but productive questions into the interpretive task.

Within an educational context, the current aim of policy translation is to achieve policy coherence by strategically and structurally aligning components, enabling whole system reform. While acknowledging the importance of this coherence conceptualisation, the current literature perspective primarily emphasises message conveyance, and lacks a dimension that identifies policy coherence as the result of how individuals, including middle leaders, interpret and translate policy into actions, both individually and collectively. System middle leaders occupy a unique position within organisational structures, as they bridge the gap between executive system leaders and school- based leaders. To investigate how policy is interpreted and translated within their roles and the impact this has on attaining policy coherence, this study employed an interpretivist approach to exploratory case study methodology, grounded in a review of authoritative literature. The aim was twofold; first, to enhance understanding of policy coherence development at the system middle level by exploring the role enactment of system middle leaders within a large Australian government education system; and second, to examine the interconnectedness and impact of leaders’ role enactment on policy coherence for system reform. Findings suggest that achieving policy coherence is hindered by a lack of role clarity among system leaders, in relation to policy implementation, stemming from the inconsistent interpretation and translation of policy into system strategy documentation and a deficiency in formal policy interpretation and role induction practices. As a result, individual system leaders often turn to informal policy interpretations and interactions with peers to clarify roles, leading to role tensions, accountability ambiguity and partial policy implementation. As a result, this study concludes that the integration of role theory, policy implementation theory and organisational alignment theory offers an interpretivist insight into the development of policy coherence for system reform, illuminating a theoretical pathway and practical recommendations for systems to attain policy coherence.

Background. Spatter formation at melt pool swellings at the keyhole rear wall is a major issue for laser deep penetration welding at speeds beyond 8 m/min. A gas nozzle directed towards the keyhole, that supplies shielding gas locally, is advantageous in reducing spatter formation due to its simple utilization. However, the relationship between local gas flow, laser spot size, and the resulting effects on spatter formation at high welding speeds up to 16 m/min are not yet fully understood. Methods. The high-alloy steel AISI 304 (1.4301/X5CrNi18-10) was welded with laser spot sizes of 300 μm and 600 μm while using a specially designed gas nozzle directed to the keyhole. Constant welding depth was ensured by Optical Coherence Tomography (OCT). Spatter formation was evaluated by precision weighing of samples. Subsequent processing of high-speed images was used to evaluate spatter quantity, size, and velocity. The keyhole oscillation was determined by Fast Fourier Transform (FFT) analysis. Tracking the formation of melt pool swellings at the keyhole rear wall provided information on the upward melt flow velocity. Results. The local gas flow enabled a significant reduction in the number of spatters and loss of mass for both laser spot sizes and indicated an effect on surface tension by shielding the processing zone from the ambient atmosphere. The laser spot size affected the upward melt flow velocity and spatter velocity. Full article
