Moniz, Jorge Botelho. « Secularization in Europe : Causes, Consequences, and Cultural Diversity ». Religions 14, no 3 (21 mars 2023) : 423. http://dx.doi.org/10.3390/rel14030423.
Texte intégralRésumé :
This paper explores the timeliness and relevance of secularization theories in Europe. It seeks to understand how the classical theories of secularization—rationalization, societalization, functional differentiation, and existential security—and their theoretical innovations—namely, cultural diversity—help describe religious phenomena in a specific set of European countries—Austria, Italy, Poland, Portugal, Slovakia, and Spain. In this context, cultural diversity shows the strongest negative correlation with religiosity. These findings arise from the correlation between the different theories of secularization, the independent variables, and an index of religiosity, the dependent variable. Cultural diversity, as a good predictor to explain secularization in Europe, shows how contact with different religious and non-religious worldviews enhances a mutual fragilization that can lead individuals from uncertainty to the rejection of religious beliefs.

Frutuoso e Melo, E. P., T. Gurova, S. F. Estefen et A. Leontiev. « INTEGRITY ANALYSIS OF FLEXIBLE PIPES TENSILE ARMOUR WIRES USING NON-DESTRUCTIVE METHOD OF INVERSE MAGNETOSTRICTION : A METHOD COMPARISON ». Brazilian Journal of Petroleum and Gas 16, no 1 (28 mars 2022) : 23–31. http://dx.doi.org/10.5419/bjpg2022-0003.
Texte intégralRésumé :
Flexible pipes have been used for decades for conveying produced fluids from oil wells to floating production, for storing and offloading units, and for flowing injection fluids inside wells under the seabed. Over the years, with an increase in oil demand globally, the exploration of new and deeper oil reservoirs has become a reality. With greater water depths, the top tension of the risers has increased significantly, as well as the pressure from the water column on the pipe structure, demanding the application of bigger pipes and the use of stronger materials. Pre-salt reservoirs on the Brazilian basins are rich in carbon dioxide (CO2) and hydrogen sulfide (H2S), which are great contributors to the premature fragilization of armour wires on the top section of the flexible risers and are capable of compromising the integrity of the structure. The wire fragilization and possible breakages cannot be avoided once the riser is connected to the floating unit, but they can be monitored, to avoid a complete riser structural failure. Several systems have been developed to monitor tensile armour wires integrity, such as visual monitoring, which visually detects torsion on the structure, acoustic waves, and magnetic collar systems, which have failed to provide reliable results. As the armour wires provide axial resistance to the structures, Fiber Bragg grating is being used in modern flexibles to monitor armour wire deformation and has been delivering reliable results. Another method, the inverse magnetostriction, is being tested using an anisotropic magneto sensor to detect wire deformation and generate a 2D stress map of the measured area. In this article, two tests are performed using the same equipment, but in different specimen. One test was performed on the wires without being applied on the flexible structure. The other test was performed on a window opened on a 6” nominal bore flexible pipe, with the objective of identifying if the method is reliable in detecting armour wire failures on flexible risers. This method could read stresses variations on the armour wires, but a larger sensor could penetrate deeper on the structure and provide a sharper stress map.

Revista Brasileira de Enfermagem 71, suppl 4 (2018) : 1663–70. http://dx.doi.org/10.1590/0034-7167-2017-0072.
Texte intégralRésumé :
ABSTRACT Objective: To understand the resistance strategies adopted by undergraduate students in nursing, faced with situations of moral distress (MD). Method: Qualitative research, developed in three universities in the south of Brazil, two federal and one private, with 21 undergraduate students in nursing from December 2015 to February 2016; the data was submitted to the discursive textual analysis and Foucauldian theoretical reference. Results: Students resisting demonstrate a sense of self-preservation and moral empowerment. Moreover, non-resistance initiatives are related to the fear of possible sanctions. Thus, by resisting or not, students may experience both positive and negative repercussions. Final considerations: By resisting, students aim to defend what they believe to be right, demonstrating their moral empowerment in the face of their moral distress. However, the exercise of disciplinary power seems to contribute to their moral fragilization, making it difficult to implement resistance strategies.

Texte intégralRésumé :
It is generally accepted that finding a place in the working world is very important for identity development. Given that adolescents nowadays have to face a fragilization of the job market, the question of how this experience affects adolescent identity development is discussed. It will be shown that the work domain remains very important for identity development, and even more so as other social models of meaning making have vanished in the course of social individualization. Drawing on data from a longitudinal study based on J. E. Marcia’s Identity Status Model, various identity strategies are discussed with regard to their functional value for identity development under the actual conditions of the job market. The identity strategy of adaptive diffusion seems to be quite functional when facing an unclear situation. It is proposed that a theoretical approach that looks at individual biographical trajectories and self narratives might be useful for further research.

Texte intégralRésumé :
This consideration of COVID-19 places the pandemic in the larger context of our present-day ontology and the environmentally destructive human–nature relationship that characterizes it, exploring it in three parts. First, it sets out the problematic conceptualization of nature in the modern social imaginary by focusing upon the self in terms of its sense of identity, agency and authority. Second, it sets out how the pandemic fundamentally disrupts these three facets of the self in terms of the fragilization of economic values, the notion of unique human agency, and the limitation of the authority of discursive reason. Finally, it concludes by outlining the opportunity for a renewed relationship with nature by proposing the recovery of the premodern concepts of metaphysical participation, teleology, and rational intuition. In doing so, the pandemic crisis is considered in the wider context of the ecological crisis of the modern age, and as an opportunity for rethinking our collective concept of nature, and the place of our selves within it.

INTERNATIONAL JOURNAL OF RESEARCH IN EDUCATION HUMANITIES AND COMMERCE 05, no 03 (2024) : 288–310. http://dx.doi.org/10.37602/ijrehc.2024.5321.
Texte intégralRésumé :
This paper looks at the demise of the West Cameroon Education Board from the perspective of an outcome of financial constraints on the West Cameroon Government. It argues that the educational choices of the West Cameroon Government significantly accentuated financial constraints which contributed to the fragilization and eventual demise of the Education Board, ultimately paving the way for the interference of the Federal Government in the West Cameroon educational system. The paper uses the historical-analytical method to interpret data collected mostly from the National Archives Buea (NAB) and presents findings according to the chronological and thematic approach. It reveals that the rapid expansion of education in West Cameroon between 1961 and 1969 accentuated financial constraints on Government which helped to fragilize the Education Board. This made the West Cameroon educational system vulnerable to Federal Government interference and eventual take over by 1972. Thus, accounting for the demise of the West Cameroon Education Board.

McClymond, Michael J. « The Geist of Hegel Past and Present ». PNEUMA 40, no 1-2 (6 juin 2018) : 58–70. http://dx.doi.org/10.1163/15700747-04001034.
Texte intégralRésumé :
Abstract This essay appreciates Taylor’s qualitative (rather than quantitative) approach to secularization, which has revolutionized recent discussions of this topic. Taylor’s earlier work on Hegel provides a context for interpreting his proposal in A Secular Age that Western societies are secularly religious or religiously secular—neither devoid of concern with transcendence, nor committed to theologically definite accounts of transcendence. Two major points of critique follow—first, that Hegelianism with its “immanent frame” excludes a distinctive Christian claim regarding Jesus’s incarnation; and, second, that Taylor’s hypothesis of faith “fragilized” by the “revisability” of contemporary religion needs empirical support to be fully credible. Taylor often represents religion as a lowest-common-denominator aspiration for something higher, rather than God coming to us incarnationally (John 1:14). Deism-with-transcendence is not Christianity. Taylor’s “fragilization” theory might mean that secularity, too, is “fragilized,” and it ought to provoke pastoral reflection on how “fragilized” faith might be stabilized.

Texte intégralRésumé :
Jazz, today a broadly defined, global form of improvised music, remains a music between heaven and earth, with its roots in both nightclubs and churches. Jazz can be dance music, as well as music that triggers emotions, memories, and subjective images. It can also lead to experiences of transcendence. In which ways, though, do jazz artists connect their spiritual and religious experiences and beliefs with their individual musical language? In contrast to Western, composed sacred music, jazz generates religious meaning through its improvisatory practices, which unfold differently in each performance, depending on the performers, listeners, and performance spaces. Often, jazz musicians feel the poetic quality of their music to reside in the ambiguity and “fragile” religiosity of their music. This article discusses from a historical and contemporary perspective the “fragilization” processes at work in religiously inspired jazz. It distinguishes different levels of religious meaning, purpose, and spiritual experience. In so doing, it explores productive resonances between the characteristics of jazz and Paul Corrigan’s definition of “postsecular” American poetry written in the late twentieth and early twenty-first centuries.

Texte intégralRésumé :
This paper presents and demonstrates the development of a new lightweight coating for aluminum alloy from a novel multicomponent alloy based on the AlSiMgCu system. The coating was applied using a newly designed approach that combined high velocity oxy-fuel (HVOF) and plasma spraying processes. This hybrid technique enables the deposition of coatings with enhanced performance characteristics. The optical microscopy (OM) and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM + EDS) revealed a strong adhesion and compaction between the multicomponent coating and the A6061 substrate. The new coating improved hardness by 50% and increased electrical conductivity by approximately 3.3 times compared to the as-cast alloy. Corrosion tests showed a lower corrosion rate, comparable to thermally treated A6061 alloy. Tribological tests indicated over 20% reduction in friction and over 50% reduction in wear rate. This suggests that multicomponent aluminum coatings could improve automotive and parts in contact with hydrogen by enhancing hydrogen fragilization resistance, corrosion resistance, electrical conductivity, and wear properties, with further optimization of thermal spraying potentially boosting performance even further.

Texte intégralRésumé :
Cette recherche explore les dynamiques des paysages urbains développés en situation humide dans la métropole de Tunis, marquées par une expansion urbaine rapide. Elle adopte une approche historico-structurelle pour analyser la formation géomorphologique et une approche diachronique pour étudier l’évolution urbaine autour du lac sud de Tunis. Soutenue par des sources historiques, cartographiques, bibliographiques et des entretiens, cette approche permet de mettre en évidence les spécificités de son développement, ainsi que les moments de continuité et de rupture dans sa transformation. Pour comprendre les logiques d'implantation et examiner le paysage urbain, une approche morpho-typologique est utilisée, impliquant des analyses, multi-échelles, monographique et sociale. Elle offre un éclairage sur les paramètres d'intégration au sein du tissu urbain métropolitain et local. L'intégration des zones humides dans cet environnement urbain révèle des spécificités spatiales incluant la cohésion urbaine et une inclusion différée des fonctions urbaines, donnant lieu à des typologies variées. Cette démarche met également en évidence les divergences des besoins entre les différentes parties prenantes. Cette observation souligne l'émergence d'une nouvelle forme de paysage urbain, caractérisée par des dynamiques socio-spatiales particulières, une gouvernance limitée et une expansion urbaine rapide, menaçant ainsi la durabilité du paysage naturel. Enfin, cette recherche préconise une approche bio-médialiste pour analyser l'interaction entre l’aménagement urbain des zones humides et les exigences du développement durable afin de développer un outil d'aide à la décision visant à évaluer la durabilité des projets urbains et les ajuster si nécessaireThis research explores the dynamics of urban landscapes developed in a humid environment in the metropolis of Tunis, marked by rapid urban expansion. It adopts a historical-structural approach to analyze the geomorphological formation and a diachronic approach to study the urban evolution around the south lake of Tunis. Supported by historical, cartographic, bibliographical sources and interviews, this approach allows us to highlight the specificities of its development, as well as the moments of continuity and rupture in its transformation. To understand the logics of implantation and examine the urban landscape, a morpho-typological approach is used, involving analyses, multi-scales, monographic and social. It provides an insight into the parameters of integration within the metropolitan and local urban fabric. The integration of wetlands into this urban environment reveals spatial specificities including urban cohesion and a delayed inclusion of urban functions, giving rise to various typologies. This approach also highlights the differences in needs between different stakeholders. This observation highlights the emergence of a new form of urban landscape, characterized by particular socio-spatial dynamics, limited governance and rapid urban expansion, thus threatening the sustainability of the natural landscape. Finally, this research advocates a bio-based approach tomedia to analyse the interaction between urban wetland management and sustainable development requirements in order to develop a decision support tool to assess the sustainability of urban projects and adjust them as necessary

Texte intégralRésumé :
This chapter examines Sally Sayward Wood’s 1800 novel Julia and the Illuminated Baron in the context of the Bavarian Illuminati crisis, arguing that Wood engaged this conflict in order to address concerns about secularity in the early republic. These concerns stemmed from several developments: the rising liberal conception of rational Christianity, the New England Federalist conception of established religion as an efficient means of promoting morality in a republic, and the fragilization of faith that Charles Taylor has associated with religious pluralism. The chapter argues that Wood’s use of gothic form sought to stave off feared secularization by combining an aesthetic sense of religious wonder with Enlightened rationalism. The chapter interprets this blend as a postsecular expression of intertwined modernity and Protestantism that was essential to Wood’s Federalist conception of religion in a republic. The chapter also considers the theological and political influence of Wood’s father Nathanial Barrell’s Sandemanisnism on Wood’s conception of rational Christianity.

Texte intégralRésumé :
For centuries, the knowledges of raced mother-subjects have been denigrated, denied, and misrepresented. What might it mean, then, to bring to thought and to “speak” epistemologically and politically from this place of (m)other absence? In this chapter, the author explores such a (m)other speaking through three themes and experiences. The first is interruption and/as failure, in which the messiness of motherhood and the untimely, unruliness of children becomes present in the space-times of political encounter and foregrounds the possibilities of other affectivities of play and wonder and other rhythms of spontaneity and nonlinearity to enter as underpinnings of shared (political) collaborations and creations. The second is fragility, which is an invitation to embody stillness and silence to allow the unspeakable to emerge from wounds of coloniality and foregrounds a maternal ethic of care, mutual self-fragilization, and surrender to the unknown possibilities of Nepantla pluridiversity. The third is a methodology for healing mother-lines, which enables the recuperation of the maternal as an energy, a symbol, a memory, a story, a practice of being held, of being mothered and of mothering self, others, and cosmos. Together, these moments and experiences offer enfleshed visions with which we might co-create a (geo)politics (m)otherwise.

Dans Offshore Technology Conference. OTC, 2022. http://dx.doi.org/10.4043/32094-ms.
Texte intégralRésumé :
Abstract Jetting is a widely applied technique for conductor installation, which allows great time savings in comparison to conventional drilling and cementing of the conductor. According to Kan et al. (2018), the key parameters for a successful jetting operation are: pump rate, ratio of bit-to-conductor dimensions and bit stick-out, that is, the length of bit bottom out of conductor shoe, during jetting. The influence of these key parameters was studied, with regards to excavation rate. The present work used a finite volume method to model the impingement of maritime soil by a jetting assembly, comprised of a rotating drillbit and conductor. The soil was modeled as a highly viscous fluid, described by a modified Herschell-Bulkley viscosity model. Velocity and pressure fields were obtained for the fluid surrounding the jetting assembly. The integration of static pressure acting over certain walls allowed for the calculation of fluid forces acting on the tools. Excavation rate was measured and compared to field-obtained data, for calibration purposes. The comparison of excavation rates obtained for different configurations showed that some stick-outs were more efficient than others. By measuring the hydraulic energy of each fluid phase, it was possible to understand the physics underneath the jetting operation, which is associated to fragilizing the soil. This fragilization will eventually lead to lower drag forces, if conductor reciprocation becomes necessary.
