The Right to Religious Freedom and its Political Significance: Catholic and Islamic Approaches
It is generally agreed that the Catholic Church formally committed itself to modern human rights in 1963 as a result of Pope John XXIIIâs encyclical, Pacem in Terris.But it was the more specific historical development regarding the right to religious freedom that took place two years later at the Second Vatican Council, which really prompted global change. As Samuel Huntington wrote, the Churchâs commitment to religious liberty on the part of all persons (and to the liberty of non-religious persons) had an extraordinary impact on democracy movements around the world. Indeed, Huntington referred to these movements as a âCatholic wave.â
At a moment when democracy appears increasingly threatened by various authoritarian nationalist and populist forces across the globe, and the Islamic world, in particular, is experiencing a retreat from the hopes of the Arab Spring, it seems pertinent to explore how the right to religious freedom is conceived and practiced amongst Muslims. In the latter case, one thinks in particular of the dashed hopes in Egypt between 2011-13, which were caused, at least partly, by the lack of faith on the part of Coptic Christians and other âliberally-mindedâ citizens to the government of the Muslim Brotherhood. Unlike the Catholic Church, the Brotherhood had failed to reform itself with respect to issues such as religious freedom and thus, for many people, was simply unprepared to govern. There are, of course, practical considerations for why such reform did not take place (not least the effects of colonialism in Egypt). But what are the theological issues? In this paper, I will explore the extent to which Islam can embrace a universal right to religious freedom, bearing in mind the implications that such commitment might have not only for the citizens of Egypt, but also for Muslims (and non-Muslims) across the Islamic world
The Dignity of the Human Person: Catholic and Islamic Approaches to Human Rights
At the beginning of The Global Face of Public Faith, David Hollenbach, S.J., challenges the worldâs religious communities to relate their distinctive visions of the good human life with the growing awareness that all persons are linked in a web of global interdependence. Hollenbachâs work is founded on an understanding of the common good that he discerns at Vatican II and calls âdialogic universalism.â It is universal because humans are sufficiently alike when it comes to the requirements for their respective goods; it is dialogic because cultural differences necessitate deep intellectual engagement across traditions if they are to be bridged.
In this paper, I hope to engage in âdialogic universalismâ by exploring the confluence between Catholic and Islamic approaches to human rights. The paper is part of a broad project in comparative ethics.
The Catholic approach to human rights is premised on the dignity of the person. But the âpersonâ here is conceived, crucially, as a social creature. Thus Hollenbach writes: âCatholic thought and action in the human rights sphere ... are rooted in a communitarian alternative to liberal human rights theory.â This alternative conception defines human rights as âthe minimum conditions for life in community,â which is premised not only on the relational nature of the person (created in the image and likeness of a Trinitarian God), but also on a conception of justice as participation in the life of the human community for all persons. Consequently, rights are conceived not simply as negative immunities but more broadly as positive empowerments.
I will argue that this vision of empowering all citizens to participate in communal life is replicated in the work of Iranian Shiâite scholar Abdolkarim Soroush, for whom rights imply duties to others and thus the pursuit of social and economic justice in a democratic context
Microstructural evolution and transmutation in tungsten under ion and neutron irradiation
This study aims to compare the effects of neutron and self-ion irradiation on the mechanical properties and microstructural evolution in W. Neutron irradiation at the HFR reactor to 1.67 dpa at 800 °C resulted in the formation of large Re and Os rich clusters and voids. The post-irradiation composition was measured using APT and verfified against FISPACT modelling. The measured Re and Os concentration was used to create alloys with equivalent concentrations of Re and Os. These alloys were exposed to self-ion irradiation to a peak dose of 1.7 dpa at 800 °C. APT showed that self-ion irradiation leads to the formation of small Os clusters, wheras under neutron irradiation large Re/Os clusters form. Voids are formed by both ion and neutron irradiation, but the voids formed by neutron irradiation are larger. By comparing the behaviour of W-1.4Re and W-1.4Re-0.1Os, suppression of Re cluster formation was observed. Irradiation hardening was measured using nanoindentation and was found to be 2.7 GPa, after neutron irradiation and 1.6 GPa and 0.6 GPa for the self-ion irradiated W-1.4Re and W-1.4Re-0.1Os. The higher hardening is attributed to the barrier strength of large voids and Re/Os clusters that are observed after neutron irradiation

Brecciation at the grain scale within the lithologies of the Winchcombe Migheiâlike carbonaceous chondrite
The Migheiâlike carbonaceous (CM) chondrites have been altered to various extents by waterârock reactions on their parent asteroid(s). This aqueous processing has destroyed much of the primary mineralogy of these meteorites, and the degree of alteration is highly heterogeneous at both the macroscale and nanoscale. Many CM meteorites are also heavily brecciated juxtaposing clasts with different alteration histories. Here we present results from the fineâgrained team consortium study of the Winchcombe meteorite, a recent CM chondrite fall that is a breccia and contains eight discrete lithologies that span a range of petrologic subtypes (CM2.0â2.6) that are suspended in a cataclastic matrix. Coordinated multitechnique, multiscale analyses of this breccia reveal substantial heterogeneity in the extent of alteration, even in highly aqueously processed lithologies. Some lithologies exhibit the full range and can comprise nearly unaltered coarseâgrained primary components that are found directly alongside other coarseâgrained components that have experienced complete pseudomorphic replacement by secondary minerals. The preservation of the complete alteration sequence and pseudomorph textures showing tochiliniteâcronstedtite intergrowths are replacing carbonates suggest that CMs may be initially more carbonate rich than previously thought. This heterogeneity in aqueous alteration extent is likely due to a combination of microscale variability in permeability and water/rock ratio generating local microenvironments as has been established previously. Nevertheless, some of the disequilibrium mineral assemblages observed, such as hydrous minerals juxtaposed with surviving phases that are typically more fluid susceptible, can only be reconciled by multiple generations of alteration, disruption, and reaccretion of the CM parent body at the grain scale
Long COVID and cardiovascular disease: a prospective cohort study.
BackgroundPre-existing cardiovascular disease (CVD) or cardiovascular risk factors have been associated with an increased risk of complications following hospitalisation with COVID-19, but their impact on the rate of recovery following discharge is not known.ObjectivesTo determine whether the rate of patient-perceived recovery following hospitalisation with COVID-19 was affected by the presence of CVD or cardiovascular risk factors.MethodsIn a multicentre prospective cohort study, patients were recruited following discharge from the hospital with COVID-19 undertaking two comprehensive assessments at 5 months and 12 months. Patients were stratified by the presence of either CVD or cardiovascular risk factors prior to hospitalisation with COVID-19 and compared with controls with neither. Full recovery was determined by the response to a patient-perceived evaluation of full recovery from COVID-19 in the context of physical, physiological and cognitive determinants of health.ResultsFrom a total population of 2545 patients (38.8% women), 472 (18.5%) and 1355 (53.2%) had CVD or cardiovascular risk factors, respectively. Compared with controls (n=718), patients with CVD and cardiovascular risk factors were older and more likely to have had severe COVID-19. Full recovery was significantly lower at 12 months in patients with CVD (adjusted OR (aOR) 0.62, 95% CI 0.43 to 0.89) and cardiovascular risk factors (aOR 0.66, 95%âCI 0.50 to 0.86).ConclusionPatients with CVD or cardiovascular risk factors had a delayed recovery at 12 months following hospitalisation with COVID-19. Targeted interventions to reduce the impact of COVID-19 in patients with cardiovascular disease remain an unmet need.Trail registration numberISRCTN10980107

Correspondence Between Perceived Pubertal Development and Hormone Levels in 9-10 Year-Olds From the Adolescent Brain Cognitive Development Study.
Aim: To examine individual variability between perceived physical features and hormones of pubertal maturation in 9-10-year-old children as a function of sociodemographic characteristics.
Methods: Cross-sectional metrics of puberty were utilized from the baseline assessment of the Adolescent Brain Cognitive Development (ABCD) Studyâa multi-site sample of 9â10 year-olds (n = 11,875)âand included perceived physical features via the pubertal development scale (PDS) and child salivary hormone levels (dehydroepiandrosterone and testosterone in all, and estradiol in females). Multi-level models examined the relationships among sociodemographic measures, physical features, and hormone levels. A group factor analysis (GFA) was implemented to extract latent variables of pubertal maturation that integrated both measures of perceived physical features and hormone levels.
Results: PDS summary scores indicated more males (70%) than females (31%) were prepubertal. Perceived physical features and hormone levels were significantly associated with child\u27s weight status and income, such that more mature scores were observed among children that were overweight/obese or from households with low-income. Results from the GFA identified two latent factors that described individual differences in pubertal maturation among both females and males, with factor 1 driven by higher hormone levels, and factor 2 driven by perceived physical maturation. The correspondence between latent factor 1 scores (hormones) and latent factor 2 scores (perceived physical maturation) revealed synchronous and asynchronous relationships between hormones and concomitant physical features in this large young adolescent sample.
Conclusions: Sociodemographic measures were associated with both objective hormone and self-report physical measures of pubertal maturation in a large, diverse sample of 9-10 year-olds. The latent variables of pubertal maturation described a complex interplay between perceived physical changes and hormone levels that hallmark sexual maturation, which future studies can examine in relation to trajectories of brain maturation, risk/resilience to substance use, and other mental health outcomes
Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19
IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19.
Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19.
DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 nonâcritically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022).
INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (nâ=â257), ARB (nâ=â248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; nâ=â10), or no RAS inhibitor (control; nâ=â264) for up to 10 days.
MAIN OUTCOMES AND MEASURES The primary outcome was organ supportâfree days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes.
RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ supportâfree days among critically ill patients was 10 (â1 to 16) in the ACE inhibitor group (nâ=â231), 8 (â1 to 17) in the ARB group (nâ=â217), and 12 (0 to 17) in the control group (nâ=â231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ supportâfree days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively).
CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.
