Navigation is an important skill required for an autonomous robot, as information about the location of the robot is necessary for making decisions about upcoming events. The objective of the localization technique is “to know about the location of the collected data.” In previous works, several deep learning methods were used to detect localization, but none of them gives sufficient accuracy. To address this issue, an Enhanced Capsule Generation Adversarial Network and optimized Dual Interactive Wasserstein Generative Adversarial Network for landmark detection and localization of autonomous robots in outdoor environments (ECGAN-DIWGAN-RSO-LAR) is proposed in this manuscript. Here, the outdoor robot localization dataset is taken from the Virtual KITTI dataset. It contains two phases, which are landmark detection and localization. The landmark detection phase is determined using Enhanced Capsule Generation Adversarial Network for detecting the landmark of the captured image. Then the robot localization phase is determined using Dual Interactive Wasserstein Generative Adversarial Network (DIWGAN) for determining the robot location coordinates as well as compass orientation from identified landmarks. After that, the weight parameters of the DIWGAN are optimized by Rat Swarm Optimization (RSO) algorithm. The proposed ECGAN-DIWGAN-RSO-LAR is implemented in Python. The efficiency of the proposed ECGAN-DIWGAN-RSO-LAR technique shows higher accuracy of 22.67%, 12.45 %, and 8.89% compared to the existing methods.

We present a counterexample to [Kan08, Conjecture 14.1.6], regarding Borel equivalence relations on product spaces.

Bank distress was a defining feature of the Great Depression in the United States. Most banks, however, weathered the storm and remained in operation throughout the contraction. We show that surviving banks cut lending when depositors withdrew funds en masse during panics. This panic-induced decline in lending explains about one-third of the reduction in aggregate commercial bank lending between 1929 and 1932, more than twice as much as attributed to the failure of banks.

Fjord ecosystems serve as crucial habitats for elasmobranchs, supporting them across all life stages. Chilean Patagonia provides one of the most complex and extensive networks of fjord ecosystems in the world, displaying high marine biodiversity, including elasmobranchs. However, little is known about this ecologically important group of fishes in these ecosystems. This study investigates the biodiversity of elasmobranchs in the Comau Fjord over a period of 6 months by combining morphological and molecular data. In total, 309 specimens within a radius of 7.5 km were recorded, belonging to six families and nine species: Hexanchus griseus (77.5–178 cm LT), Notorynchus cepedianus (180.6 cm LT), Schroederichthys bivius (35–65.2 cm LT), Scymnodon macracanthus (37.3 cm LT), Centrophorus squamosus (87.4 cm LT), Deania calceus (58.3–98.6 cm LT), Squalus acanthias (25.5–101.1 cm LT), Dipturus chilensis (62.9–152 cm LT), and Dipturus trachyderma (69.8–194 cm LT). This included records of three species previously unknown in the fjord and was equivalent to nearly 20% of the elasmobranch richness found in Southern Chile. The results further suggest that the Comau Fjord could be a primary nursery ground for several species of elasmobranchs. This is the first time that a species inventory of elasmobranchs is conducted in a Chilean fjord system. The outcomes of this research provide an elasmobranch species checklist with biological aspects from the Comau Fjord, which are essential data to inform decision makers, conservation managers, and future research.

Does John Rawls’s justice as fairness require virtuous citizens to eschew self-interested motivation in favor of motivation by the aim to promote justice when making decisions about their labor or investment participation in their society’s economy? Analyzing Rawls’s ideas of advantage and of legitimate ends and tracing the purpose and implementation of his difference principle, the article shows how G. A. Cohen’s critique of Rawls’s allowance of productive incentives reflects misunderstandings of Rawls’s theoretical aims and of the fundamental liberalism of Rawls’s well-ordered society. In that society, political civility permits making such decisions by appeal to each citizen’s self-interested aims and values.

Most twin registries have not systematically collected the data required to determine gender identity, which has limited opportunities to evaluate potential familial contributors to gender diversity. This study addresses this gap by analyzing responses to gender identity questions introduced in Twins Research Australia’s 2023 survey. Among 4475 respondents (mean age 52.2 years, SD = 15.3), 36 (0.8%) indicated a transgender or gender diverse identity, which is consistent with population-based estimates of gender diversity internationally. Gender diversity co-occurred in 2/19 monozygotic pairs and 0/8 dizygotic pairs, giving rise to tetrachoric correlations of 0.62 (95% CI [0.33, 0.87]) and 0.00 (95% CI [0.00, 0.88]), respectively. These results broadly align with previous concordance estimates from twin studies that were specifically focused on gender identity. Although limited by a small sample size, these findings demonstrate the feasibility and utility of systematically collecting gender identity data through routine twin registry surveys.

Groote Eylandt, one of Australia’s largest islands, is situated north of Darwin in the Northern Territory. The Groote Eylandt Mining Company (GEMCO) is the island’s most prominent employer, having begun open-cut manganese mining in 1964. GEMCO’s long-term presence has led to a seemingly intractable conundrum: economically crucial for First Peoples yet accompanied by chronic socioeconomic and cultural problems. Huge disparities have emerged between the wealthy mining town of Alyangula (with over 90 per cent of its population non-First Peoples and with a predominantly fly-in-fly-out workforce) and the Angurugu and Umbakumba townships (over 90 per cent First Peoples populations). Adopting a theoretical framework of organisational legitimacy, this paper evaluates how enterprise bargaining might contribute to achieving Groote Eylandt’s First Peoples employment and broader community objectives (including health, housing, and environmental restoration). At present, GEMCO’s ‘Employer of Choice’ Indigenous employment strategy comprises three main goals: (1) establishing and maintaining a qualified mentor network; (2) implementing culturally appropriate recruitment and induction processes; and (3) maintaining training programmes that provide the necessary skills for specific jobs. Yet, despite an expansion of mining operations and associated services, First Peoples employment opportunities and participation in the townships have stagnated, while underemployment has become endemic. The paper summarises GEMCO’s Employer of Choice promises and then evaluates these promises against employment and community outcomes. It goes on to explore the possibilities of enterprise bargaining at GEMCO, illustrating how future enterprise agreements might enable the achievement of First Peoples intersecting employment and community goals.

Pteridium aquilinum, commonly known as bracken, is a fern species distributed in temperate and subtropical regions. In Iran, it primarily grows in isolated populations in the northern regions, and its genetic structure, gene flow and population genetics are not well understood. This study aimed to investigate gene flow and genetic diversity in 11 geographical populations of P. aquilinum in Iran for the first time. A total of 133 plants from different populations were examined, and both morphological and genetic diversity were assessed using start codon targeted (SCoT) molecular markers. Results showed genetic and morphological admixture within populations, likely due to the high mobility of dispersal units in this species. Significant genetic differences were found among populations, but a high degree of genetic variability was observed within individual populations. Additionally, there was a significant correlation between geographical and genetic distances, indicating gene flow between populations. The assignment test revealed genetic admixture among plants from different populations, and Gst analysis of SCoT loci yielded Nm = 0.95, confirming gene flow among the populations. Overall, this study demonstrates that the Iranian populations of P. aquilinum maintain substantial gene flow, which may contribute to the long-term survival and adaptability of this species in the region.

Welfare state research is at a theoretical impasse insofar as it does not systematically speak to the types of social policy effort that may have not only redistributive but also productive consequences. Cautioning against imprudent use of the social investment label this paper argues for a better understanding of how traditional social policies have enabled society’s adaptation to socioeconomic changes and prevented costly experiences of poverty. Synthesizing ideas drawn from development studies in the Global South and welfare state studies in the Global North, and elaborating on the inclusive strand of welfare developmentalism, the paper conceptualizes what allows existing social policies to be simultaneously protective and productive. It reviews current welfare state research and argues that developmentalist ideas help re-centre the (re)productive role of social policy. It proposes principles for thinking coherently about what makes existing welfare state policies developmental, challenging their characterization as exclusively passive or activating. Recognizing the productive impact of existing social policies requires that we explicitly rethink how welfare state policy effort is understood.

The provision of formal childcare services holds significant potential benefits in addressing challenges posed by population ageing, labour shortages and welfare dependency. However, existing literature indicates persistent differentials in formal childcare uptake by migration background, with limited understanding of underlying demand-side factors. This study addresses this gap by comprehensively examining demographic, socio-economic, employment-related and attitudinal characteristics as potential explanations for these disparities. Utilising data from the Generations and Gender Survey across seven high-income countries, our findings reveal that whereas differentials for migrants’ descendants are limited and insignificant even without controlling for background variables, the negative differential for migrants disappears almost completely. Socio-economic status and particularly employment potential emerge as a key explanatory factors alongside differential attitudes towards maternal employment, which seem to play a role in some contexts, yet not in others. Cross-country differences in the results are discussed in the face of socio-economic gradients in formal childcare uptake, migrant-native gaps in the labour market and below-demand supply of formal childcare, yet also plead for future research interacting demand- and supply-side factors for a larger set of countries. In conclusion, this study reveals the intricate interplay of demographic, socio-economic and attitudinal factors underlying migrant–native disparities in formal childcare uptake.
