The career of the composer, performer, educator and diplomat Hans-Joachim Koellreutter was exceptionally varied, taking place over three continents. A refugee from Nazi Germany, he is primarily known for introducing serialism to Brazil. However, he not only returned to his native Germany for a short period but also lived and worked in India and Japan, before going back to Brazil. His life and work epitomize the role played by migrants in constructing a global diasporic network, illustrating both the promises and the shortcomings of global musical modernism. The consequences he drew, however, drove him to embrace a form of universalism that was at odds with the increasing ideological polarization of the 1970s and 1980s, notably in a Latin American intellectual climate dominated by dependency theory.

In this first report of endoparasites from endemic land-mammals of the Galápagos Islands, we describe a new species of cestode of the genus Raillietina (Cyclophyllidea: Davaineidae) from a species of Nesoryzomys and summarize the extent of helminth parasitism in both oryzomyine endemics and introduced species of Rattus. Up to the current time, no helminth parasites have been reported from rodents of the Galápagos, and little work has yet been done describing and synthesizing Galápagos parasite diversity. In historical times, several species of autochthonous rodents have occupied the islands including: Nesoryzomys narboroughi Heller 1904, N. fernandinae Hutterer and Hirsch 1979, N. swarthi Orr, 1938, and Aegialomys galapagoensis (Waterhouse, 1839). Colonization of the islands by humans brought 3 known species of synanthropic rodents: Rattus rattus, R. norvegicus, and Mus musculus which are suspected to have caused the extinction of at least 3 other oryzomyines in historical times.

Norcross's recent book has a two-part title: Morality by Degrees: Reasons without Demands. In this essay I focus on the second part of the title – the idea that there are moral reasons without demands. I do not think that it is at all obvious what this means, and whether it is distinct from Norcross's central (and compelling) idea, that moral reasons come in degrees. I explore several possible ways of cashing out a distinctive claim that morality does not make demands, and argue that we should not accept that morality does not make demands. It does make demands, but it sometimes makes them in degrees.

I agree that a good pensions system should embody some form of collective risk pooling and that this would be to the advantage of everyone. There are some difficult issues of adverse selection to be solved, however. Moreover, egalitarian concerns are of crucial importance in most countries and they require to go further than collective risk pooling and to take into account that society is more than a system of self-interested monetary transfers between and within cohorts.

In this article, I discuss some ways in which my experience, as a sexual assault survivor, has often been disregarded. It was disregarded when it occurred, by a crowd of people who watched. It has also been disregarded, however, in certain sorts of conversations—that occur within feminist communities—about sexual violence. The latter forms of disregard stem from the fact that I am male, and so do not fit many peoples’ preconceptions about survivors of sexual assault. After discussing these different forms of disregard and how they relate, I raise some difficult questions concerning whether, and how, conversations about sexual violence should make room for experiences like mine. In closing, I propose tentative, schematic answers to those questions.

Accurate channel characterization is extremely helpful in channel estimation, channel coding, and many other parts of communication system design and can effectively reduce overhead. Ray tracing (RT) shows accurate channel reconstruction for specific maps, but the multipath propagation in indoor scenes is far more complex than in outdoor scenes leading to a challenge for RT. This work presents and validates an RT tool for a massive multiple-input multiple-output (MIMO) system in the millimeter-wave frequency bands with the associated channel beamforming algorithm and provides ideas for channel estimation algorithm in subsequent MIMO systems. The impact of the order of interactions, e.g. reflections and diffractions on the channel impulse response reconstruction are analyzed in the RT simulation. The comparison between RT simulated and measured results shows a reasonable level of agreement. The presented RT tool that can provide complete and accurate channel information is of high value for the design of reliable communication systems.

This work is concerned with the exponential turnpike property for optimal control problems of particle systems and their mean-field limit. Under the assumption of the strict dissipativity of the cost function, exponential estimates for both optimal states and optimal control are proven. Moreover, we show that all the results for particle systems can be preserved under the limit in the case of infinitely many particles.

Gram-negative bacteremia and antimicrobial resistance cause significant morbidity and mortality. Strategies are needed to optimize rapid and effective antimicrobial therapy with early de-escalation. In this brief, we describe the utilization of multiplex polymerase chain reaction rapid diagnostic technology for the early de-escalation of broad-spectrum antimicrobials in patients with Enterobacterales bacteremia.

This is a continuation of the paper [J. Symb. Log. 87 (2022), 1065–1092]. For an ideal $\mathcal {I}$ on $\omega $ we denote $\mathcal {D}_{\mathcal {I}}=\{f\in \omega ^{\omega }: f^{-1}[\{n\}]\in \mathcal {I} \text { for every } n\in \omega \}$ and write $f\leq _{\mathcal {I}} g$ if $\{n\in \omega :f(n)>g(n)\}\in \mathcal {I}$, where $f,g\in \omega ^{\omega }$.

We study the cardinal numbers $\mathfrak {b}(\geq _{\mathcal {I}}\cap (\mathcal {D}_{\mathcal {I}} \times \mathcal {D}_{\mathcal {I}}))$ describing the smallest sizes of subsets of $\mathcal {D}_{\mathcal {I}}$ that are unbounded from below with respect to $\leq _{\mathcal {I}}$.

In particular, we examine the relationships of $\mathfrak {b}(\geq _{\mathcal {I}}\cap (\mathcal {D}_{\mathcal {I}} \times \mathcal {D}_{\mathcal {I}}))$ with the dominating number $\mathfrak {d}$. We show that, consistently, $\mathfrak {b}(\geq _{\mathcal {I}}\cap (\mathcal {D}_{\mathcal {I}} \times \mathcal {D}_{\mathcal {I}}))>\mathfrak {d}$ for some ideal $\mathcal {I}$, however $\mathfrak {b}(\geq _{\mathcal {I}}\cap (\mathcal {D}_{\mathcal {I}} \times \mathcal {D}_{\mathcal {I}}))\leq \mathfrak {d}$ for all analytic ideals $\mathcal {I}$. Moreover, we give example of a Borel ideal with $\mathfrak {b}(\geq _{\mathcal {I}}\cap (\mathcal {D}_{\mathcal {I}} \times \mathcal {D}_{\mathcal {I}}))=\operatorname {\mathrm {add}}(\mathcal {M})$.

This study evaluates the implementation of a blood culture (BCx) algorithm in the neurology ICU (NICU) to reduce BCx event (BCE) rates. Results show a reduction in BCE rates, without increasing adverse outcomes. The findings support the feasibility of BCx algorithms for improving diagnostic stewardship in the specialized NICU population.

Age estimates from bomb 14C dating conflict with a well-recognized age reading protocol (grinding, polishing and staining in the sagittal plane) for otoliths of European eel (Anguilla anguilla). Proper alignment of calculated hatch years for 14C measurements taken from the earliest otolith growth—among the smallest otolith extractions to date for successful 14C analysis due to the advent of gas-AMS—was not achieved using age estimates from an accepted method. The realignment of otolith 14C values to a tropical bomb 14C reference chronology, which is most applicable to the Sargasso Sea as the natal origin of European eel, led to an increase of the original age estimates by 8 to 32 years. A maximum age of approximately 46 years was determined for the European eel specimen with the most massive otolith, of which mass is a reasonable proxy for age and was instrumental in identifying age estimate discrepancies. By extending the otolith mass-to-age relationships from this study to the most massive otoliths available from archived otoliths of Norway, an increase of up to several decades from the original otolith age estimates was discovered, leading to support for a potential lifespan of 70–100 years in the natural environment.

Subject-Sensitive Invariantism (SSI) and Epistemic Contextualism (EC) are rival theories in epistemology. Both involve shifting epistemic standards, but they differ in how they explain this shiftiness. SSI is primarily a metaphysical thesis about the knowledge relation, whereas EC is primarily a semantic thesis about knowledge attributions. This paper revisits some of the central problems faced by SSI, especially those concerning Dutch books and third-person knowledge ascriptions. The main aim is to show that existing responses that stay true to SSI do not succeed, leaving SSI in serious jeopardy. Some strategies put forward by, or on behalf of, SSI-friendly philosophers fare better. But these involve forsaking central features of SSI, ceding ground to EC, and falling back on a defense of impurism. I sketch what such an impurist fallback position might look like and argue that the more ground it cedes to EC, the more attractive it will be. It is shown that such an impurist, contextualist position can handle all the difficulties I discuss in relation to SSI. The paper concludes by briefly considering what new challenges this kind of position faces instead.

Given a unital $C^*$-algebra and a faithful trace, we prove that the topology on the associated density space induced by the $C^*$-norm is finer than the Bures metric topology. We also provide an example when this containment is strict. Next, we provide a metric on the density space induced by a quantum metric in the sense of Rieffel and prove that the induced topology is the same as the topology induced by the Bures metric and $C^*$-norm when the $C^*$-algebra is assumed to be finite dimensional. Finally, we provide an example where the Bures metric and induced quantum metric are not metric equivalent. Thus, we provide a bridge between these aspects of quantum information theory and noncommutative metric geometry.

The overuse and inappropriate use of antimicrobials have led to environmental waste and drug shortages. This challenges the ecological and economical sustainability of our healthcare system and worsens antimicrobial resistance.

Antimicrobial stewardship programs (ASP) commonly consider the cost of drug acquisition but may be failing to recognize the hidden costs of multi-dose intravenous regimens including additional nursing administration time, tubing and fluids, and potentially increased hospital length of stay. They also rarely consider the environmental impact of medical waste creation and disposal, which contributes to the global antimicrobial resistance crisis. These costs are harder to calculate but crucial to a comprehensive assessment of a medication’s total impact. In this invited commentary, we provide an example of a stewardship evaluation at our institution focused on changing from meropenem (MER) to ertapenem (ETP) for infections caused by extended-spectrum beta-lactamase producing organisms. We found that despite an increase in acquisition costs, changing from MER to ETP is associated with overall savings and decreased waste production. A secondary analysis suggests that stay length may also be improved with this substitution.

We present a holistic approach to antimicrobial stewardship that considers the total cost of an antimicrobial. By broadening their view to include hidden costs and secondary effects, ASPs can further demonstrate their value to the healthcare system, reduce resistance, and improve their environmental impact.

Epistemic trust in others frequently cannot be disentangled from interpersonal trust more generally, but the epistemic implications of how we affectively express our trust in others are under-investigated. This essay claims that gratitude, despite its empirically undeniable importance to human flourishing generally, is also important epistemically and in several intersecting ways. To be grateful to a person is to represent the world differently in key respects. Gratitude, even if it is for past non-epistemic benefits, should play an important role in shaping who we epistemically rely on. Gratitude for specifically epistemic benefits is an important way in which we show our attunement to epistemic value and contribute to the incentive structures that make much of our public knowledge and informational ecosystems possible. Likewise, ingratitude is a crippling epistemic vice that renders our dependence on quality sources of information fragile and vulnerable to capture by misinformation.

A defeater is, very broadly, a consideration that reduces or completely takes away justification from a subject’s belief about a certain proposition. According to a widely endorsed view, justifiers and defeaters require evidential support. However, a number of philosophers argue that unjustified beliefs can serve as defeaters as well. Call the former type of defeater an ‘evidential defeater’ and the latter a ‘doxastic defeater’. Doxastic defeaters are highly controversial. First of all, they seem to be flatly incompatible with evidentialism. Moreover and more alarmingly, if we accept that unjustified beliefs can be defeaters, we have to accept that unjustified beliefs can serve as justifiers as well. A further unwelcome implication is that epistemically irresponsible subjects could immunise themselves from defeat by generating their own defeater-defeaters. Problems like these have led philosophers to reject doxastic defeaters altogether. This paper argues that doxastic defeaters are intelligible given a dualistic conception of rationality.
