In the 2022–2023 season, more than 104,000 tourists visited Antarctica. This represents an increase of more than 40 percent compared to the 2019–2020 pre-pandemic season. This Current Development discusses this trend and the limits of the Antarctic Treaty Consultative Parties, which govern on the basis of consensus, in responding with regulatory action. Options for strengthening regulation in this area are also considered.

This is the first study reporting parasites from the freshwater cyprinid Oxynoemacheilus angorae (Steindachner 1897) caught in Nilüfer Stream, Bursa, in the Northwest Anatolian Region of Turkey. Allocreadium bursensis n. sp. was described from the intesine of O.angorae based on morphological and genetic characteristics. Allocreadium bursensis n. sp. was differentiated from other Allocreadium spp. in having a combination of external (ventral and oral suckers ratio; body length and width and its ratio to forebody) and internal (cirrus pouch position; uterus extension in hindbody; egg size; disposition of anterior border of vitellarium; esophagus length) features. Phylogenetic hypotheses based on maximum parsimony, maximum likelihood, Bayesian inferrence, and neighbor joining analyses of sequence data strongly supported the hypothesis that A. bursensis is nested within the clade of Allocreadium species hosted by cypriniform fish, and it is more closely related to the Far Eastern species A. pseudoisoporum (Primorsky region, Russia) than to the African A. apokryfi. According to genetic p-distances, the taxonomic status of trematodes collected in Turkey was established as independent relative to nine of the valid Allocreadium spp.: 1.8–5.8% in 28S gene and 18.8–22.6% in cox1 gene. The present study increases the number of Allocreadium species and their definitive hosts recorded in Turkey and raises the number of Palearctic representatives of Allocreadium spp. to 26.

In this article, I present a novel argument against abortion. In short, what makes it wrong to kill someone is that they are a counterfactual person; counterfactual persons are individuals such that, were they not killed, they would have been persons. My view accommodates two intuitions which many views concerning the wrongness of killing fail to account for: embryo rescue cases and the impermissibility of infanticide. The view avoids embryo rescue cases because embryos in the rescue scenarios are not counterfactual people: they are not counterfactual people because it is false to say that, were they not killed, they would have been persons. As a result, it does not follow from my account that there is a prohibition against allowing embryos to die. On the other hand, infants are counterfactual people: an infant is an individual such that, were she not killed, she would have been a person.

The cemetery at Sutton Hoo in East Suffolk includes tumuli dating to the sixth–seventh centuries ad. The largest contained an intact ship-burial. The man commemorated is not identifiable, but is often presumed to be Rædwald, rex Anglorum c ad599–624/5. Excavation was curtailed by the outbreak of war in 1939. Despite subsequent re-excavation and lengthy research, questions remain.

Information dispersed in the definitive publication is correlated and developed. Digital 3D imaging of the ship’s iron fastenings are used here to extrapolate curved lines of missing rivets and superimpose them on the burial chamber plan. A digital roof reconstruction is also presented.

Mechanisms of collapse of the objects are deduced from their positioning and damage, revealing space for access to the chamber. A cross-section depicts the calculated height of the deck and known tilt of the ship. Residues of phosphate, Middle Eastern bitumen, tar and tape cumulatively suggest embalming practices. A temporary coffin and a bed on which possessions were placed are proposed.

The most valuable object relinquished is deduced to be the ship. Fragments of a possible anchor are identified. The suggested identification of the iron stand as a raised light would allow supporting ships to follow.

Grassland habitats currently face severe anthropogenic exploitation, thereby affecting the survival of grassland-dependent biodiversity globally. The biodiversity-rich grasslands of India lack quantitative spatiotemporal information on their status. We evaluated the status of upper Gangetic Plains grasslands in 2015 and compared it with those from 1985, 1995 and 2005. On-ground mapping and visual classifications revealed a 57% decline in these grasslands between 1985 (418 km2) and 2015 (178 km2), mostly driven by habitat conversion (74% contribution by cropland). Limited radiotelemetry data from endemic swamp deer indicated a possible grassland-dominated average home range size of 1.02 km2, and these patches were highly preferred (average Ivlev’s index = 0.85) over other land-use classes at both spatial and temporal scales. Camera-trapping within the core habitats suggests the critical use of these patches as fawning/breeding grounds. Habitat suitability analysis indicates only c. 17% of the area along the Ganges is suitable as swamp deer habitat. We recommend the protection of these critical grassland patches to maintain ‘dynamic corridors’, with restoration and other management approaches involving multiple stakeholders to ensure the survival of this critical ecosystem.

Se presentan los primeros resultados del análisis de pieles procesadas recuperadas en el sitio Puerto Tranquilo 1, ubicado en el extremo norte de la Isla Victoria, en el Parque Nacional Nahuel Huapi, Provincia de Neuquén, Argentina. El material estudiado proviene de un nivel tardío, por encima de un fogón fechado en 640 ± 60 años aP (1288–1431 cal dC). El conjunto incluye tanto fragmentos de piel con pelo como depilados, con costuras de tendón y pelo, pintados y con reparaciones. Se aplicó una metodología específica para el análisis de las pieles y las fibras, con una descripción técnico-morfológica detallada a partir del análisis macro- y microscópico (SEM/óptico). Las características de la médula y de la cutícula de las fibras permitieron la identificación de Lama guanicoe y Mustelidae (cf. Galictis). Se aplicaron estrategias analíticas y metodológicas novedosas y se generaron datos acerca de las diferentes dimensiones del uso humano de los recursos faunísticos y de la producción de tecnologías en el área boscoso-lacustre norpatagónica. La comparación con otras evidencias arqueológicas, etnográficas y etnohistóricas permitió reconocer rasgos tecnológicos recurrentes en la preparación de las pieles y en la manufactura de artefactos, como parte del proceso productivo del cuero en Norpatagonia.

Family functioning may serve as protective or risk factors in the development of youth psychopathology. However, few studies have examined the potentially reciprocal relation between child psychopathology and family functioning. To fill this gap in the literature, this study tested for time-ordered associations between measures of family functioning (e.g., cohesion, conflict, and emotional expressiveness) and child psychopathology (e.g., total behavior problems, externalizing, and internalizing problems) using data from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN; N = 1143, 52.3% female, Nwaves = 5). We used a random-intercept cross-lagged panel model to identify whether child psychopathology preceded and predicted family functioning, the reverse, or both processes occurred simultaneously. At the between-person level, families who tended to have more cohesion, who lacked conflict, and who expressed their emotions had lower levels of child psychopathology. At the within-person level in childhood, we found minimal evidence for time-ordered associations. In adolescence, however, a clear pattern whereby early psychopathology consistently predicted subsequent family functioning emerged, and the reverse direction was rarely found. Results indicate a complex dynamic relation between the family unit and child that have important implications for developmental models that contextualize risk and resilience within the family unit.

This essay revisits the question of mass destruction through the perspectives offered by postcolonial thinkers.

After the Second World War, the US government established a new oil order, forming close ties with three major oil companies—Standard Vacuum, Shell, and California-Texas—referred to as the ‘Three Sisters’ in Korea, which was newly liberated from Japanese colonialism. Even after the South Korean government was established, the US government and the Three Sisters worked to maintain the order. Using the carrot of the Economic Cooperation Administration (ECA) funds, in 1949 the US government pressured the South Korean government into oil agreements that would facilitate the supply of petroleum products to the country. The 1949 oil agreements were completed after three rounds of negotiations. The process of signing the agreements was not limited to the import, storage, and sale of petroleum products in exchange for US aid to South Korea. It also sought to respond to the various interests of Koreans who wanted to create an independent economic structure in the midst of establishing a new government. This article explores the three rounds of negotiations for the 1949 oil agreements whereby the symbiotic relationship between the US government and the Three Sisters was realized in partnership with the interests of the South Korean government. Furthermore, it seeks to broaden the research on the history of Korean oil by promoting an understanding of how US oil policy affected Korea immediately after its liberation from Japanese colonial rule.

The existence of isometric embedding of $S_q^m$ into $S_p^n$, where $1\leq p\neq q\leq \infty$ and $m,n\geq 2$, has been recently studied in [6]. In this article, we extend the study of isometric embeddability beyond the above-mentioned range of $p$ and $q$. More precisely, we show that there is no isometric embedding of the commutative quasi-Banach space $\ell _q^m(\mathbb {R})$ into $\ell _p^n(\mathbb {R})$, where $(q,p)\in (0,\infty )\times (0,1)$ and $p\neq q$. As non-commutative quasi-Banach spaces, we show that there is no isometric embedding of $S_q^m$ into $S_p^n$, where $(q,p)\in (0,2)\setminus \{1\}\times (0,1)$ $\cup \, \{1\}\times (0,1)\setminus \left \{\!\frac {1}{n}:n\in \mathbb {N}\right \}$ $\cup \, \{\infty \}\times (0,1)\setminus \left \{\!\frac {1}{n}:n\in \mathbb {N}\right \}$ and $p\neq q$. Moreover, in some restrictive cases, we also show that there is no isometric embedding of $S_q^m$ into $S_p^n$, where $(q,p)\in [2, \infty )\times (0,1)$. A new tool in our paper is the non-commutative Clarkson's inequality for Schatten class operators. Other tools involved are the Kato–Rellich theorem and multiple operator integrals in perturbation theory, followed by intricate computations involving power-series analysis.

Passported benefits are additional benefits provided to individual or households based on a previous eligibility to a “primary” social security benefit. Although passported benefits should be easier to claim, in reality the claiming process is often cumbersome and results in low take-up. Drawing on an Israeli case study, we offer a conceptual framework to categorize and analyse the varieties of passported benefits along five dimensions: the eligibility role of primary cash benefits; automation level; legal status; type of service delivery; and the degree of decentralization. The administrative burden literature is employed to make sense of the paradox of passported benefits becoming a site for administrative burden. Using our conceptual framework and drawing on interviews with officials and claimants, we demonstrate why some passported benefits are more user-friendly while others tend to become administratively burdensome.

Kant’s philosophy of natural science has traditionally concentrated on a host of issues including the role of laws of nature and teleological judgements. However, so far, the literature has made virtually no contact with the no less important tradition in Kant’s legal and political philosophy. This article explores one aspect of such connection in relation to the normative foundations of Kant’s notion of cosmopolitan right. I argue that Kant’s argument for cosmopolitan right is based on two main premises: the first is what I call the law of equilibrium, and the second is the premise of physical interaction (commercium in Latin) at work behind what Kant called the original ‘community of land’. The article argues that the relevant notion of community qua commercium should be understood in the context of Kant’s metaphysics of nature as a ‘real community of substances’ governed by a dynamical law of equality of action and reaction. This metaphysical-causal interpretive reading has far-reaching implications for the foundations of cosmopolitan right and its scope of applicability well beyond Kant’s envisaged right to universal hospitality.

To gain insights into the trichurid diversity in pre-Hispanic remains of South American camelids (SACs), as well as into modern SAC populations, a bibliographic search was carried out to find parasitological studies. Results showed that a total of 17 studies were performed at archaeological and paleontological sites, in which a total of 213 samples were examined. The sample set was used as the unit of analysis, and 83% of 52 pre-Hispanic sample sets were positive for parasites. Parasitological studies confirmed the pre-Hispanic presence of diverse trichurids: two Trichuris species and capillariid eggs with morphological differences that allowed them to be assigned to three different species. Currently, the richness of the native trichurid assemblages in SACs has been extended by the inclusion of two species (Trichuris sp. 2 and Capillariinae gen. sp. 1). Modern T. tenuis Chandler, 1930, considered SAC-specific, would have invaded SAC populations during the European colonization. The estimate of regional and temporal trichurid prevalence and paleoecological information allowed us to propose a possible origin for some of them. Although the present analysis is exploratory, it should stimulate future studies about the biogeographic history of SAC helminths, provide relevant information to improve descriptions of the Holocene ecology, and identify threatened helminths.

Point-of-care ultrasound (PoCUS) is used by health care professionals of various specialties worldwide, with excellent results demonstrating significant potential to advance patient care. However, in low resource areas of the world, where other imaging modalities are scarce and the potential of handheld pocket-sized PoCUS devices with great versatility and increasing affordability seems most significant, its use is far from being widespread. In this report, our group of Chadian, Israeli, and Canadian physicians with experience in rural, military, and conflict zone medical aid, discusses the barriers to the implementation of PoCUS in low resource areas and offers potential solutions.

In this paper, we investigate the regularity properties and determine the almost sure multifractal spectrum of a class of random functions constructed as sums of pulses with random dilations and translations. In addition, the continuity moduli of the sample paths of these stochastic processes are investigated.
