Re-Membering Catholicity: Higher Education, Racial Justice, and the Spirituality of the Posthuman University

In the reinscribing of white supremacy in the United States, the contemporary university as a place of exclusion presents a problem of religion. Approaching religion as “the search for depth” and addressing the “techno-myths” of betterment, longevity, and the rituals of enacting these myths that capture today’s social imaginaries, this paper proposes an alternative to religious faith in “rising” and the rhetoric of the contemporary American technocratic-meritrocratic paradigm. Adopting the posthumanist methodologies of reflexivity and diffraction, the author argues for an embodied catholicity of the university as a community, an open system rather than a pre-formed locus to which racially minoritized students are “added” or “included”. In advancing the co-creativity of a Catholic-pluriversal university via an ethic of love and care, the author presents a Christian spirituality that is itself a technology that offers the hope of enacting a more life-giving congruence between the sacred and the secular than the myth of Manifest Destiny and the racialized violence that is the continued manifestation of that mythos. Embodied in the posthuman mystic’s practices of “re-memory,” the author presents Christianity as a performative-pluralistic religion of evolution, one of common action with the potential to draw into something new the energies of creativity in today’s university.

A review on Charakokta Shonitasthapaka mahakashaya: Ayurvedic as well as modern view.

Blood being one among the seven tissues has its significant role in regulating the function of all vital organs and giving life to individuals. Without proper quantity and quality of blood, the body cannot remain healthy. The fourth chapter of Charaka samhita ie related to fifty various groups. In each group, 10 herbs are included having common action. Shonita sthapaka mahakashaya is pronounced for action related to restoring the normalcy of blood. Shonita sthapaka mahakashaya is very specific and only mahakashaya in which only 5 medicines of herbal origin, one metallic compound, one jantav dravya and two byproducts and Mrutkapala. Shonitasthapakaa gana included actions like Raktashodhana [haemostatic], Raktastambhana [ blood coagulation], Raktavilayaka [blood thinning], Raktavardhanaa [ haemopoitic]. Rakta and pitta dosha are the same in nature, so Rakta is mainly vitiated by pitta dosha. Thus, dravyas included in Shonitasthapaka gana have pittashamak properties. So, according to different conditions of Raktavikara [disorders related to blood], we can categorize Shonitasthapaka dravyas in treatment.

„Handeln statt Hoffen“. Zur Gemeinschaftsanrufung durch Attribution von Verantwortungsgefühlen im medialen Diskurs zur Seenotrettung von Carola Rackete im Sommer 2019

<p>The article addresses a narrative of communanlity stemming primarily from feelings of responsibility. Referencing selected media reports on Carola Rackete’s sea rescue operation in 2019, the article discusses the circumstances under which a society calls on its individual members to act in a spirit of responsibility for their community - and at which point this common hope actually results in common action. The paper focuses on what constitutes responsible communities real and imagined, i.e. the discursive processes by which a community is invoked through the attribution of feelings of responsibility. The article employs methodological elements from linguistic and social science discourse research.</p>

Fundamental Pedagogical Aspects for the Implementation of Models-Based Practice in Physical Education

The implementation of pedagogical models (PMs) in the subject of Physical Education (PE) is presented as a pedagogical approach that is based on the educational context as a means to overcome the serious limitations that arise from traditional approaches. The effective implementation of this approach has demonstrated benefits in terms of student motivation, student involvement and improved learning. Thus, its application and international relevance, the variability of content covered, the possibility of replicability in a variety of contexts and the fact that it favors a reflective framework and common action by teachers are some of the reasons that justify its use. In this sense, the need for teacher training, as well as the intention to generate more scientific evidence based on its application in the classroom, are some of the key aspects to be taken into account for its implementation and consequent consolidation in the educational field.

STUDIES ON THE IMPACT OF WORK FROM HOME DURING COVID-19 PANDEMIC: A SYSTEMATIC LITERATURE REVIEW

When the pandemic outbreak happened back in the year 2020, the Government and the policymakers took preventive steps and directive measures to sustain social movement and infection among the citizens. Common action that has been taken globally was the implementation of lockdown. Consequently, non-essential businesses or organizations had to resolve to transition from central office to work-from-home for as long as the lockdown period ended. This has brought a greater change in the world of work and boosted the experimentation of work-from-home arrangements worldwide. Despite it being a practice that some may have experienced before, it is still relatively uncommon and unusual to be done on such a large scale for some countries. Therefore, many are interested to see the outcome of work-from-home, the impact it had on employers, employees, and companies. However, the ample amount of works of literature made it hard to distinguish the direction and trend of this research. This paper aims to identify and highlight the major findings on the impacts of work-from-home by reviewing 55 published papers in the year between 2020 to 2021 and analyze them through a thematic analysis. The results show 60 percent of these studies are covered by the field of social sciences which both involve developed and developing countries. Nevertheless, the impact of work-from-home was found common as the problem used to arise even before the pandemic happened. This gives an opportunity in future studies to finally resolve some of these problems if work-from-home soon becomes the 'new norm' in the world of work.

Alinsky revisited: ‘rubbing raw the resentments of the people’

This chapter analyses American community organiser Saul D. Alinsky's theoretical background and shows that his understanding of 'resentment' was drawn from the ethics of the Scottish philosopher Adam Smith and the German philosopher Friedrich Nietzsche. 'Rubbing raw the resentments' and 'to fan the sores of discontent' are Alinsky's medical metaphors describing his technique to understand frustration and aggression, to cool down emotions and to transform its energy into common action and political negotiation. He tried to empower the people by turning personal discontents and problems into public issues. What are the lessons to be learned from Alinsky for contemporary community development responses to populism? His analysis and his confrontations with McCarthyism and proto-fascist agitator Father McCoughlin provide examples of ways of meeting the challenges we are facing in Germany today, where new prophets of deceit operating through populist politics again carry out the fine art of propaganda, using the new forms of mass communication and the opportunities of social media. Ultimately, the chapter offers a German perspective to the international discussion on community development, populism, and democratic culture.

Traube–Hering waves are formed by interaction of respiratory sinus arrhythmia and pulse pressure modulation in healthy men

Variability in blood pressure has become an important metric to consider as more is learned about the link between excessive blood pressure variability and adverse health outcomes. In this study using slow deep breathing in human subjects, we found that heart rate and pulse pressure variations have comparable effects on the amplitude of blood pressure waves, and it is the common action of the two that defines the phase relationship between respiration and blood pressure oscillations.

Changing Route: Common Action on Food Systems Transformation in the Mediterranean

The Coronavirus pandemic has revealed the fragility of our food systems, affecting all dimensions of food security and nutrition across the world. It has highlighted how deeply our world is interconnected and the importance of better recognising and understanding the interconnections that are intrinsic to these systems and their key role in pursuit of the SDGs of the 2030 Agenda. There is now, more than ever, a stronger need for a “route change” towards a common action on food systems transformation. Dialogues among all stakeholders to redesign the future of tomorrow’s food systems are needed to trigger collective, multi-stakeholder actions on the ground, at local, regional and global level, towards more sustainable food systems, linking sustainable food production to more healthy and sustainable food consumption. In this context CIHEAM, FAO, and the Union for the Mediterranean Secretariat (UfMS) initiated in 2019, a joint collaborative effort for the establishment of a multi-stakeholder platform on Sustainable Food Systems in the Mediterranean to accelerate the shift towards the Agenda 2030 in the Mediterranean region, with the Mediterranean diet acting as a driver.

Mary as Mediator

Theological identity, for many, provides a powerful social role. These distinct theological locations proscribe very different places from which to think about the particular woman named Mary, the mother of Jesus. Her story has been a site of great conflict, but this chapter argues it can also provide a mediated space where various theological identities can meet, converse, and act on the social issues informed by her particularities as a poor, pregnant, Jewish woman. This chapter takes up two of the most contested theological questions about her story, her sinlessness and her ministry. New Testament exegesis supports the conclusion that the text allows for different doctrinal decisions on these issues, but prohibits any stance that would so distance her from others so that her calls for justice are ignored in favour of continued oppression against the marginalized. Instead, her story invites honest conversation and common action.
