The Principle of Total Evidence: Justification and Political Significance

AbstractThe principle of total evidence says that one should conditionalize one’s degrees of belief on one’s total evidence. In the first part, I propose a justification of this principle in terms of its epistemic optimality. The justification is based on a proof of I. J. Good and embedded into a new account of epistemology based on optimality-justifications. In the second part, I discuss an apparent conflict between the principle of total evidence and the political demands of anti-discrimination. These demands require, for example, that information about the sex of the applicant for a job should not be included in the relevant evidence. I argue that if one assesses the applicant’s qualification in terms of those properties that are directly causally relevant for the job performance, then properties that are merely indirectly relevant, such as sex, race, or age, are screened off, i.e., become irrelevant. So, the apparent conflict disappears.

Ação Direta de Inconstitucionalidade nº 5.779: a preponderância da efetividade do direito à saúde sobre a hierarquia das normas jurídicas

Objective: To reflect on whether the hierarchy of legal norms should be used as an infallible method of solution even when an apparent conflict between legal norms involving health law can be better resolved through a technical decision by the competent regulatory agency. Methodology: data was collected. In particular, Resolução de Diretoria Colegiada nº 52/2011, Law nº 13.454/2017 and Ação Direta de Inconstitucionalidade nº 5.779-DF. Specialized legal doctrine was sought on the central and peripheral themes. The data collected was analyzed using the critical-narrative review technique. Results: In Brazil, the adoption of regulatory agencies as normative agents and regulators of economic activities has made it possible to make decisions based less on political criteria than on technical criteria. The legislator, anchored in political criteria, according to the judiciary, cannot go beyond technical criteria. Conclusion: the judgment in Ação Direta de Inconstitucionalidade nº 5.779 shows that today's concept and the legal nature of the right to health impose new legal paradigms that validate the role of regulatory agencies (making technical decisions in favor of maximum effectiveness of the right to health), even to the detriment of politically legitimized decisions by the legislature. The formal paradigm cannot prevent the materialization of the right. Submission: 03/18/24| Review: 08/16/24| Approval: 08/16/24

Comment on “Tunneling-tip-induced collapse of the charge gap in the excitonic insulator Ta2NiSe5 ”

In this study, we investigate the discrepancy between the estimate of Q. He [], who observed a remarkable collapse of the exciton gap in Ta2NiSe5 due to the electrostatic field between the scanning tunneling microscope (STM) tip and the sample, and that of a recent angle-resolved photoemission spectroscopy investigation [C. Chen , ]. It is proposed that a critical factor contributing to this discrepancy is due to He 's assumption of a constant work function of the STM tip. This assumption led to an underestimation of the tip-induced electric field. Using a literature value for the sample work function, a more substantial electric field strength is obtained, which resolves the apparent conflict between the doping estimates of these two techniques. Furthermore, our findings highlight the importance of the STM tip condition, which can significantly impact the tip work function and, consequently, influence the doping estimation in experiments involving tip-induced electric fields.

The role of ultra-processed foods in plant-based diets: associations with human health and environmental sustainability.

Investigate the associations of ultra-processed foods (UPF) in healthful (hPDI) and unhealthful (uPDI) plant-based diets with all-cause mortality, greenhouse gas emissions (GHGE), and blue water consumption (BWC). Analyses were based on 35,030 participants (20-70 years; 74% females) from the EPIC-NL cohort who were followed up from 1993 to 1997 through 2014. Plant-based diet indices (hPDI and uPDI) and UPF consumption were calculated from a validated FFQ, assessed at baseline. Cox proportional hazard and multiple linear regression models were used to estimate associations between combined quartiles of the PDI indices and UPF consumption. With lower hPDI and higher UPF diets as the reference, we observed the following. Risk estimates of all-cause mortality were 0.98 (95% CI: 0.83, 1.16) for lower UPF consumption, 0.86 (95% CI: 0.68, 1.08) for higher hPDI, and 0.78 (95% CI: 0.66, 0.89) for combined higher hPDI and lower UPF consumption. Results with the uPDI were inconclusive. Mean differences in GHGE and BWC were 1.4% (95% CI: 0.3, 2.4) and 1.6% (95% CI: -0.5, 3.7) for lower UPF consumption, -7.4% (95% CI: -8.6, -6.4) and 9.6% (95% CI: 7.2, 12.0) for higher hPDI, and - 6.8% (95% CI: -7.4, -6.1) and 13.1% (95% CI: 11.6, 14.8) for combined higher hPDI and lower UPF consumption. No apparent conflict between environmental impacts was observed for the uPDI; GHGE and BWC were lower for higher uPDI scores. Mortality risk and environmental impacts were mostly associated with the amount of plant-based foods and to a lesser extent UPF in the diet. Shifting to a more healthful plant-based diet could improve human health and reduce most aspects of environmental impact (GHGE, but not BWC) irrespective of UPF consumption.

Housing Limitarianism: What’s Wrong with Owning Excess Homes?

ABSTRACT There is a growing contention in the Housing Justice movement from activists, theorists, and politicians that not only should everyone have enough housing, but there is something wrong with having too much of it. This paper provides a framework to articulate and defend efforts to create housing wealth ceilings. Building on the work of Ingrid Robeyns, it develops the moral and political doctrine of housing limitarianism. This doctrine asserts it is morally wrong to have too much housing while others, human or animal, do not have enough, and that governments ought to limit the excessive acquisition/consumption of housing by individuals and corporations. I employ the Rawlsian ideal of property-owning democracy to argue for the dispersal of homeownership throughout society. Lastly, I discuss how housing justice can ethically negotiate the apparent conflict between increasing the supply of affordable housing and the preservation of natural habitat for wildlife.

Boolean map and object reconcile as the unit of visual working memory.

The unit of visual working memory is a fundamental issue under debate in the fields of cognitive psychology and neuroscience, with some traditional research suggesting that it is an object, while other recent studies demonstrating that a Boolean map offers a better account. The controversy surrounding the unit of visual working memory often centers on the representation of objects consist of same dimensional features (e.g. bicolor objects). For 2 colors in a bicolor object, some behavioral studies have suggested that they need to be represented by separate units, while some other studies using electrophysiological measures have found that they can be represented within a single unit. This apparent conflict hints that Boolean map and object may reconcile as the unit of visual working memory. Adopting the contralateral delay activity as an electrophysiological marker of visual working memory, experiments 1 and 2 consistently found that the contralateral delay activity amplitude for memorizing bicolor circles at P7/P8 conformed the Boolean map-based storage throughout the whole maintenance, while the contralateral delay activity amplitude at P3/P4 just conformed the object-based storage during the early period. It suggests though Boolean map got stronger supporting evidence than object, they 2 may coexist as the unit of visual working memory.

AGEL: Is the Conflict Real? Investigating Galaxy Evolution Models Using Strong Lensing at 0.3 < z < 0.9

Observed evolution of the total mass distribution with redshift is crucial to testing galaxy evolution theories. To measure the total mass distribution, strong gravitational lenses complement the resolved dynamical observations that are currently limited to z ≲ 0.5. Here we present the lens models for a pilot sample of seven galaxy-scale lenses from the ASTRO3D Galaxy Evolution with Lenses (AGEL) survey. The AGEL lenses, modeled using HST/WFC3-F140W images with Gravitational Lens Efficient Explorer (GLEE) software, have deflector redshifts in the range 0.3 < z defl < 0.9. Assuming a power-law density profile with slope γ, we measure the total density profile for the deflector galaxies via lens modeling. We also measure the stellar velocity dispersions (σ obs) for four lenses and obtain σ obs from SDSS-BOSS for the remaining lenses to test our lens models by comparing observed and model-predicted velocity dispersions. For the seven AGEL lenses, we measure an average density profile slope of −1.95 ± 0.09 and a γ–z relation that does not evolve with redshift at z < 1. Although our result is consistent with some observations and simulations, it differs from other studies at z < 1 that suggest the γ–z relation evolves with redshift. The apparent conflicts among observations and simulations may be due to a combination of (1) systematics in the lensing and dynamical modeling; (2) challenges in comparing observations with simulations; and (3) assuming a simple power law for the total mass distribution. By providing more lenses at z defl > 0.5, the AGEL survey will provide stronger constraints on whether the mass profiles evolve with redshift as predicted by current theoretical models.

Thermoeconomic analysis of sCO2 power cycles

AbstractThe second‐law analysis evaluates the irreversibilities of a process. Systematic study of the relationship between thermodynamic efficiency and process modifications enhances process synthesis. The Allam cycle is an oxy‐fuel combustion cycle with nearly complete carbon capture that offers greater efficiency than current electricity generating systems. This study applies lost work analysis to the original Allam cycle and three modifications to obtain the distribution of irreversibilities and the effects of different configurations among potential process improvements for more sustainable power generation. The major inefficiencies are from the combustors and heat exchangers. We also examine the economic profitability of the alternatives. The largest equipment costs are for the turbines, compressors, and recuperators. We find that improving efficiency leads to less economic return; a configuration with partial compression has the highest efficiency, while the original Allam cycle has the highest profitability. We discuss how to resolve this apparent conflict between sustainability and profitability.

Constitutional mismatch repair deficiency mimicking Lynch syndrome is associated with hypomorphic mismatch repair gene variants

Lynch syndrome (LS) and constitutional mismatch repair deficiency (CMMRD) are distinct cancer syndromes caused, respectively, by mono- and bi-allelic germline mismatch repair (MMR) variants. LS predisposes to mainly gastrointestinal and genitourinary cancers in adulthood. CMMRD predisposes to brain, haematological, and LS-spectrum cancers from childhood. Two suspected LS patients with first cancer diagnosis aged 27 or 38 years were found to be homozygous for an MMR (likely) pathogenic variant, MSH6 c.3226C>T (p.(Arg1076Cys)), or variant of uncertain significance (VUS), MLH1 c.306G>A (p.(Glu102=)). MLH1 c.306G>A was shown to cause leaky exon 3 skipping. The apparent genotype-phenotype conflict was resolved by detection of constitutional microsatellite instability in both patients, a hallmark feature of CMMRD. A hypomorphic effect of these and other variants found in additional late onset CMMRD cases, identified by literature review, likely explains a LS-like phenotype. CMMRD testing in carriers of compound heterozygous or homozygous MMR VUS may find similar cases and novel hypomorphic variants. Individualised management of mono- and bi-allelic carriers of hypomorphic MMR variants is needed until we better characterise the associated phenotypes.

So…….You Want to be a Peer Reviewer?

Peer review is essential to preserving the integrity of the scientific publication process. Peer reviewers must adhere to the norms of the peer review process, including confidentiality, avoiding actual or apparent conflicts of interest, timeliness, constructiveness, and thoroughness. This mini review will discuss some of the different formats in which peer review might occur, as well as advantages and disadvantages of each. The topics then shift to providing advice for prospective reviewers, as well as a suggested format for use in writing a review.

Imperfect legislative agreements and judicial policymaking. A theoretical inquiry

ABSTRACT This article examines how imperfect legislative agreements offer an opportunity for higher courts’ intervention in policymaking. In concrete terms, it explains that lawmakers in certain situations avoid resolving apparent conflicts of interest due to high transaction costs in the legislative process, maintaining statutory criteria considered transparently inefficient or by simply developing regulatory arrangements with a significant degree of indeterminacy. Employing a simplified model of rational choice behaviour, the article asserts that those scenarios constitute an opportunity for strategic involvement of the higher courts in crafting public policy. As an unintended consequence of the imperfect legislative agreements, justices look at them as an indicator that members of the other branches of government have reached weak political compromises or are unable to impose their policy preferences. Therefore, justices can exercise discretion, foreseeing prospects to increase their authority while the risk of an overruling or the implementation of other retaliatory measures remains low.

Multiple Beads on a String: Dark-matter-deficient Galaxy Formation in a Mini-Bullet Satellite–Satellite Galaxy Collision

Dark-matter-deficient galaxies (DMDGs) discovered in the survey of ultra-diffuse galaxies (UDGs), in apparent conflict with standard cold dark matter, may be produced by high-velocity galaxy–galaxy collisions, the so-called Mini-Bullet scenario. Recent observations of an aligned trail of 7–11 UDGs near NGC 1052, including DMDGs DF2 and DF4, suggesting a common formation event, ∼8.9 ± 1.5 Gyr ago, provide a test.Hydro/N-body simulations, supplemented by galaxy orbit integrations, demonstrate that satellite–satellite collisions outside the host-galaxy virial radius can reproduce the observed UDGs in the NGC 1052 group. A trail of ∼10 DMDGs is shown to form, including 2 massive ones that replicate the observed motions of DF2 and DF4. The linear relation, v = A x + v 0, conjectured previously to relate positions ( x ) and velocities ( v ) of the aligned DMDGs as a signature of the collision event, is approximately obeyed, but individual DMDGs can deviate significantly from it. The progenitors whose collision spawned the trail of DMDGs survive the collision without themselves becoming DMDGs. We predict that one progenitor is located at the end of the trail, which can be tested by observing the difference between its stars, formed pre-collision, from those of the DMDGs, formed post-collision. By contrast, stellar ages and metallicities of the DMDGs are nearly identical. We further offer a hint that the tidal field of host NGC 1052 may contribute to making DMDGs diffuse. ΛCDM simulation in a 100 cMpc box finds our required initial conditions ∼10 times at z < 3. These results indicate current observations are consistent with the Mini-Bullet scenario.

Rethinking pathways to the dioecy-polyploidy association: Genera with many dioecious species have fewer polyploids.

Numerous studies have found a positive association between dioecy and polyploidy; however, this association presents a theoretical conflict: While polyploids are predicted to benefit from self-reproduction for successful establishment, dioecious species cannot self-reproduce. We propose a theoretical framework to resolve this apparent conflict. We hypothesize that the inability of dioecious species to self-reproduce hinders their establishment as polyploids. We therefore expect that genera with many dioecious species have fewer polyploids, leading to a negative association between polyploidy and dioecy across genera. We used three publicly available databases to determine ploidy and sexual systems for 131 genera and 546 species. We quantified (1) the relationship between the frequency of polyploid species and the frequency of dioecious species across genera, and (2) the proportion of polyploids with hermaphroditism and dioecy across species, adjusting for phylogenetic history. Across genera, we found a negative relationship between the proportion of polyploids and the proportion of dioecious species, a consistent trend across clades. Across all species, we found that sexual system (dioecious or not) was not associated with polyploidy. Polyploids are rare in genera in which the majority of species are dioecious, consistent with the theory that self-reproduction favors polyploid establishment. The low frequency of polyploidy among dioecious species indicates the association is not as widespread as previously suggested. Our findings are consistent with previous studies identifying a positive relationship between the two traits, but only if polyploidy promotes a transition to dioecy, and not the reverse.

The right to science or to Wissenschaft? Five lessons from the travaux préparatoires

This article identifies novel insights from a detailed analysis of the travaux préparatoires of the right to science provisions in the Universal Declaration of Human Rights (UDHR) and the International Covenant on Economic, Social and Cultural Rights (ICESCR). It makes five main contributions. First, it demonstrates the bidirectional influence between the UDHR and the earlier American Declaration of the Rights and Duties of Man in the formulation of the right to science, as opposed to unidirectional borrowing. Second, it traces the origins of Article 15 ICESCR to the UNESCO Constitution and argues that Article 15, specifically subclauses 2–4, were intended as implementation measures, though Article 15(3) was elevated into a separate and additional obligation due to its perceived importance for scientific and creative progress. Third, it clarifies an apparent conflict between drafting history and subsequent instruments concerning scientific purpose by distinguishing the development and use of science. Fourth, it suggests facilitating the search for truth as an unarticulated object and purpose of these provisions. Finally, it shows that many drafters acknowledged a broad scope of ‘science’ beyond the natural sciences. Overall, this article elucidates overlooked aspects of the travaux to inform contemporary debates on this important yet obscure right.

Performing Reparative Craft: Oreet Ashery’s Passing through Metal

P assing through Metal (2017–18), a performance by queer interdisciplinary artist Oreet Ashery, is the focus of this paper. Featuring the enigmatic intervention of a death metal band into a collective of knitters, the performance follows this basic structure: first, forty knitters, each seated with contact microphones attached to the metal needles; second, a band bursts into the acoustics of the space. Commissioned in 2017 by Lilith Performance Studio in Malmö, Sweden, Ashery’s bringing together of death metal and knitting queers Sweden’s industrious cottage industry history and disrupts the predominantly white male metal scenes. Taking care not to be disparaging, writer David Keenan describes the paranoid, destructive energy behind such musics as adolescent, whereas knitting is an ostensibly quieter reparative practice. The apparent conflicts between the performative elements in the piece will be explored through the prism of Melanie Klein’s and Eve Kosofsky Sedgwick’s theories on the depressive-reparative position and its oscillatory relationship to the paranoid. With this framing, it is argued that Ashery’s body of work frequently characterizes a culture at odds with itself, and through this framework the generative possibilities and pathetic inadequacies of both reparative work and adolescent destruction will be addressed.

Exploring the benefits and risks of displayed passion in entrepreneurial pitches

ABSTRACT Should entrepreneurs display their passion when pitching a business idea to potential funders? Entrepreneurial passion is important, but evidence about the effect of displayed passion in venture financing appears contradictory. We integrated the emotions-as-social-information perspective and regulatory focus theory in two studies using crowdfunding projects and survey responses (total N = 2,187 participants) to reveal that entrepreneurs’ displayed passion exerts two opposing effects: increasing the likelihood of funding success by fostering potential investors’ enthusiasm, while decreasing the likelihood of funding success by intensifying potential investors’ perception of risk. We also showed that an entrepreneur’s use of promotion-focused language can mitigate the negative effects of displayed passion. The results illuminate the links between displayed passion and investors’ funding decisions, resolve apparent conflict in prior findings, offer guidance for future study, and have practical implications for entrepreneurs and investors.

Fostering Medical Students’ Commitment to Beneficence in Ethics Education

Fostering Medical Students’ Commitment to Beneficence in Ethics Education

Vaccine nationalism is not unethical from a political ethics perspective: Learning from the global COVID-19 vaccine distribution failure

During the COVID-19 pandemic, there was an apparent conflict between medical and political ethics regarding the ethical evaluation of vaccine nationalism ― the “My Country First” vaccine allocation policy. Medical ethics sees this policy as selfish, leading to an unequal global vaccine allocation. Political ethics, however, argues that this policy is in the national interest and should not be labeled unethical. This conflict is one of the fundamental reasons why various medical ethics-based global vaccine allocation schemes, including the COVID-19 Vaccines Global Access Facility, have been difficult to implement. As long as the international community remains composed of different countries, vaccine nationalism will be difficult to eradicate. Therefore, international organizations, including World Health Organization, should focus on universal vaccine access rather than allocation based solely on medical ethics. Countries, especially low-income countries, must strengthen vaccine-related capacity-building to immunize their citizens as early as possible. Otherwise, they may still be at the bottom of the global vaccine allocation queue when the next globally challenging outbreak occurs. High-income countries should work to expand the distribution of vaccines, including donating vaccines to countries that lack them, helping other countries set up vaccine factories, and sharing vaccine production technology and intellectual property, which is the right choice from medical and political ethics perspectives.

Synthetic Biology and the Goals of Conservation

ABSTRACT The introduction of new genetic material into wild populations, using novel biotechnology, has the potential to fortify populations against existential threats, and, controversially, create wild genetically modified populations. The introduction of new genetic variation into populations, which will have an ongoing future in areas of conservation interest, complicates long-held values in conservation science and park management. I discuss and problematize, in light of genetic intervention, what I consider the three core goals of conservation science: biodiversity, ecosystem services, and wilderness. This uneasy relationship, however, does not forgo the use of such interventions. I argue there is a case for the application of this technology within some interpretations of the moral frameworks of wilderness and biodiversity, despite apparent conflict between these values and the technology, and the possibility that this technology's use displays some limitations of the ecosystem services framework. Ultimately, the advent of biotechnology assisted restoration highlights the need for us to reevaluate our ethical concepts of conservation at times of global environmental and technological change.

Two-Body Hadronic Weak Decays of Bottomed Hadrons

The structure of light diquarks plays a crucial role in formation of exotic hadrons beyond the conventional quark model, especially with regard to the line shapes of bottomed hadron decays. We study the two-body hadronic weak decays of bottomed baryons and bottomed mesons to probe the light diquark structure and to pin down the quark–quark correlations in the diquark picture. It is found that the light diquark does not favor a compact structure. For instance, the isoscalar diquark [ud] in Λb0 can be easily split and rearranged to form Σc(*)D¯(*) via the color-suppressed transition. This provides a hint that the hidden charm pentaquark states produced in Λb0 decays could be the Σc(*)D¯(*) hadronic molecular candidates. This quantitative study resolves the apparent conflicts between the production mechanism and the molecular nature of these Pc states observed in experiment.
