Studies on authorship in archaeology have revealed inequalities that influence interpretations of archaeological narratives. Like other countries with rich archaeological heritage, Guatemala has drawn a diverse pool of researchers for decades, owing to its renowned Maya heritage. This study examines how gender and nationality shape knowledge production in Guatemalan archaeology. We analyze publication trends in Guatemala’s most prominent publication venue, the memoirs of the annual archaeology symposium, and two international journals: Latin American Antiquity and Estudios de Cultura Maya. We also incorporate alumni data from Guatemalan universities and responses from an exploratory survey of 103 local archaeologists regarding occupations, identities, and perceptions of inequalities. Our study reveals that although Guatemalan archaeology has been characterized by relative gender parity, the dissemination of academic knowledge has been predominantly led by men, even during periods when there have been more female professional archaeologists. These disparities likely stem from several factors, including occupational variations, traditional gender-role expectations, and institutional barriers. While men have traditionally led the dissemination of academic knowledge, women have achieved leadership in other domains. This study highlights the current state of diversity in Guatemalan archaeology and serves as a first step toward building a more inclusive archaeological community.
Non-profits require highly motivated and professional employees to fulfill their potential to contribute to community development and well-being. But what motivates jobseekers to seek employment in non-profits over governmental organizations, and what makes non-profits more attractive than governmental organizations? Leveraging positive religious and spiritual development and self-determination theories, we theorize that spiritual and religious individuals are more likely to prefer working for non-profits over governmental organizations. This preference occurs because religious and spiritual individuals have stronger traits of self-sacrifice and compassion that motivate them to take a job that offers more non-material incentives than material incentives, leading to a preference for non-profits over governmental organizations. The serial mediation model identifies how compassion and self-sacrifice mediate the effects of spiritual intelligence and religiosity on job motivation; while job motivation mediates the effect of self-sacrifice and compassion on career preference and sector attractiveness. We validate our serial mediation-based conceptual framework based on responses from 306 job seekers in India. The results support our hypotheses, where individuals high on spirituality and religiosity prefer working in non-profits over governmental sector, owing to higher compassion, and self-sacrificing tendencies.
Feminist and gender-focused archaeology have advanced our field, but this research is marginalized rather than integrated into broader analyses of societies. To address this situation, I analyzed publication content and related equity issues. I reviewed major archaeology journals to see how participation in and citation of household archaeology changed from 1990 to 2019. Since 2000, interest in gender has held steady, with about half of household archaeology articles mentioning gender, women, or children. Gender is most prevalent in historical archaeology. Meanwhile, feminism is rarely mentioned. When women publish on household archaeology, their work is as highly cited as men’s. In terms of citation counts, neither men nor women are punished for focusing on gender. I hope these data encourage archaeologists to submit articles addressing gender to high-impact journals. To more fully integrate gender into our field, US-based archaeologists could address underrepresentation of women authors in journals, reluctance to engage with politics and activism, privileging of quantitative data, academic hiring, and strategic uses of different kinds of journals.
Scholars are increasingly interrogating distinctions between ‘war time’ and ‘peace time’, but what happens when time itself becomes a weapon of war or, even, a model of conflict response. Focusing on the case study of the first armed UN mission, the United Nations Emergency Force (UNEF) to Sinai and the Gaza Strip during the 1956 Suez Crisis, I examine the mission’s attempt to replace the Israeli invasion and establish an open-ended international administration on the Gaza Strip. Using archival documents and photographs, this paper explores how UN operations in Palestine shaped temporal assumptions about the population and the conflict. I argue that the Suez Crisis ruptured an UN-managed temporal paralysis on the Gaza Strip which opened up opportunities for new futures in Gaza, as well as anxiety to return to controlled paralysis. Examining both Palestinian and international reactions to the UN occupation, I show how the ‘Gaza exception’ policy transformed international perceptions of the region – its past, present, and future. Thus, by focusing on the moment of the brief UN occupation, I argue that this international intervention shifted global perceptions of the strip from a ‘frozen’ site of past conflict into a space of unfinished ownership and future potentiality.
This article explores the multidimensional issue of drug policy in Turkey during the interwar era and its intersection with economic policy, public health concerns, and psychiatric discourse. As one of the world’s leading producers of opium, Turkey resisted international opium control conventions until the 1930s, viewing them as a means of Western economic domination. Parallel to this, domestic public debates increasingly framed addiction in medical terms, through the lenses of eugenics, nationalism, and racialized rhetoric. The article highlights the pivotal role of the psychiatrist Mazhar Osman in shaping these discourses, particularly through his reports to the League of Nations. In these reports, Osman portrayed addiction as a symptom of moral decay and presented Turkey’s repressive minority policies as a success in combatting the illegal drug trade. Drawing on archival materials, including government documents, medical literature, and contemporary newspapers, this study argues that Turkey’s opposition to international drug conventions was rooted not only in economic self-interest, but also in broader struggles over national sovereignty, modernity and the racialized construction of addiction as a social threat.
Tropical dry forests (TDFs), which comprise 40% of tropical forests and are most widespread in the Neotropics, remain under-researched. TDFs support high biodiversity and are inhabited by many Indigenous communities, making their degradation a critical socio-environmental problem, yet local drivers of deforestation are overlooked. Mexico holds the largest extent of TDFs, yet these ecosystems face high levels of disturbance and limited protection. This study models the impacts of global environmental change on a TDF in southern Mexico, focusing on land-cover dynamics, biodiversity and nature’s contributions to people. We applied spatially explicit land-cover modelling under three long-term scenarios (Optimistic, Business as Usual and Pessimistic) based on varying rates of change, climate and socioeconomic conditions. Drivers were dynamically updated to reflect plausible trajectories. By overlaying land cover with species distribution data, we identified farming expansion as the primary threat to 35 endemic vertebrate species, 27 of which face a high risk of extinction. This biodiversity loss compromises ecosystem functioning and weakens the resilience of local communities. We recommend integrating conservation with Indigenous participation in sustainable land-use practices, aligned with the Kunming–Montreal Global Biodiversity Framework to halt species extinction and conserve ecosystems.
This article introduces the concept of valorization to theorize how voluntary social welfare organizations foster social inclusion for marginalized individuals. Departing from dominant frameworks that view volunteering primarily as a pathway to labor market integration, the study conceptualizes inclusion as a dialectical process of valorization—co-constructed through sustained interaction between volunteers and enabling organizational settings. Based on qualitative interviews with 13 marginalized volunteers and three organizational leaders in Danish voluntary social welfare organizations, the analysis identifies three interrelated phases of the valorization process: (1) the discovery of informal, biographically rooted competencies, (2) the reinforcement of self-efficacy through organizational validation, and (3) the internalization of new narratives of self-worth. Rather than facilitating capital accumulation, these organizations enable recognition of informal resources often overlooked in formal institutions.
The Curaco Batholith, located in Northern Patagonia (Argentina), is a Late Triassic-Early Jurassic composite intrusive body comprising monzogranites, granodiorites, diorites, granite porphyry, muscovite-bearing leucogranites, mylonites, and andesitic-rhyolitic dikes. This study integrates field mapping, petrographic-microstructural observations, rock magnetic data, and anisotropy of magnetic susceptibility (AMS) analyses across these different facies to investigate the emplacement history of the Curaco batholith within an E-W-trending deformation area. Microstructural analysis allowed classification into three categories: (1) magmatic, encompassing sub-magmatic to high-temperature solid-state, (2) medium-temperature solid-state, and (3) low-temperature solid-state. These were systematically correlated with AMS data. The magnetic fabrics in most lithologies exhibit general NW-SE-trending foliations with subhorizontal to moderately plunging lineations, consistent across the batholith. AMS fabrics within and around the La Seña and Pangaré shear zones share this orientation but display variable dips and lineation plunges. The observed parallelism between magnetic and mesoscopic fabrics, including microgranular enclaves, syn-plutonic dikes, and magmatic foliations in granitic rocks, suggests that strain was recorded progressively during crystallization. The coherent alignment of magmatic, solid-state, and AMS fabrics supports a syn-tectonic emplacement model. At the regional scale, the batholith developed under E-W dextral strike-slip tectonics, whereas at the local scale, emplacement occurred within a right-stepping releasing stepover, producing transtensional conditions. This deformation pattern reflects continuous strain during magma cooling, from magmatic flow to solid-state deformation at progressively lower temperatures, ultimately approaching the brittle-ductile transition. The Curaco Batholith thus records the emplacement of a syn-extensional magma body during the early stages of Gondwana break-up, providing insights into magmatism-transtension interactions in continental settings.
To describe the revised Asia Pacific Society of Infection Control (APSIC) Guidelines for Prevention of Central Line Associated Blood Stream Infections (CLABSI) 2024.
Design:
The revised guidelines was developed by infection prevention and control experts and key opinion leaders from Asia Pacific.
Setting:
Emphasis on practical implementation of Central Line Insertion and Maintenance Bundles using quality improvement approach is recommended towards the goal of achieving zero CLABSI in any healthcare setting.
Patients or participants:
Any patients with a central line in a healthcare setting
Interventions:
Literature search was done for recent international updates in CLABSI prevention. Recommendations were evaluated for practical and feasible implementation in low resourced settings.
Results:
The key recommendations are listed in the APSIC CLABSI insertion and maintenance guidelines. Additional measures are recommended for use where CLABSI rates remain high despite implementation of all preventive strategies to achieve institutional goals.
Conclusions:
A surveillance program is recommended to monitor outcomes and compliance with bundles. Ongoing review of the performance data with appropriate interventions made should facilitate efforts towards zero CLABSI rate.
Hard landings are a perennial issue for airlines, resulting in lost aircraft utilisation, ground delays and landing gear damage. With the Boeing 787 series in widespread use with airlines globally, this study aims to quantify the influence of several flight parameters on the vertical load factor at touchdown for the Boeing 787 using data from the aircraft’s quick access recorder (QAR). A hierarchical regression analysis was performed on 13 variables that were grouped into three sets: (A) Aircraft and Environmental Conditions, (B) Flare Parameters and (C) Final Manoeuvres. These sets were entered sequentially to predict touchdown load factor in Gs. The final model was statistically significant (p < 0.001), explaining 14% of the variance in touchdown G. Final Manoeuvres (Set C) was the largest unique contributor, accounting for 5% of the variance. Three flight parameters were found to be significant predictors: windspeed, vertical speed at 20ft AGL and stick pitch (forward). For the latter, pitch-down control input resulted in an average increase of 0.08G compared to a stick-neutral input.
Torque-driven steering of magnetic micro/nanobots in fluids is one of the most promising platforms of controlled propulsion at the small scales, and it has been the focus of modern biomedical applications. The propulsion is a result of rotation–translation coupling and it requires non-trivial (e.g. chiral) geometry of the nanobot and the weak (millitesla) rotating magnetic field. At submicron scale, nanobots are subjected to intrinsic thermal fluctuations that may become comparable to the magnetic driving. We investigate the effect of Brownian fluctuations on the actuation and steering of magnetized nanohelices in a viscous fluid numerically, using Langevin simulations. First, we assume force-free propulsion and study the effect of thermal fluctuations on driven rotation and steering of the nanohelix. We demonstrate that the random Brownian torque dramatically impedes the nanobot’s propulsion via (i) hindering the rate of the forced rotation; (ii) altering its orientation, i.e. increasing the precession angle of the forced rotations. We further demonstrate that even for fairly low thermal noise (rotational Péclet number, $ \textit{Pe} \approx 10$), the angular velocity of the forced rotation drops by $2$–$3$ times, while the precession angle increases two fold as compared with the non-Brownian limit. Both these factors contribute to an approximately $2.5$-fold reduction of the propulsion velocity. Furthermore, when the magnitude of thermal fluctuations is comparable to magnetic driving ($ \textit{Pe} \approx 1$), we find an order-of-magnitude reduction of the propulsion speed. Although inclusion of a stochastic thermal force does not alter the propulsion velocity on average, it considerably increases its variance and further impedes the propeller’s steerability.
Between 2021 and 2023, the Center for Applied Isotope Studies (CAIS) tested over 500 samples for biobased carbon content under the United States Department of Agriculture’s (USDA) Biopreferred Program using the American Society for Testing and Materials (ASTM) biobased testing standard D6866. We describe some of the novel approaches we used to prepare a diverse array of biobased products and summarize those radiocarbon test results and success rates in meeting the USDA Minimum Biobased Content (MBC).
Suzume no tojimari (2022) depicts the coming-of-age road trip of a teenage girl through abandoned places, in order to save Japan from giant earthquake worms, and to confront her own past of 3/11. With hyperrealistic visuals and references to Shinto mythology and folklore traditions, the movie constructs a correlation between human misbehavior and natural disasters. This narrative indicates the restoration of a mythological unity of Japanese land, people, and culture to prevent earthquakes, and to overcome personal and social issues, echoing Japanese national conservative discourse. By doing so, the movie puts moral responsibility to the individual to cope with disasters and decline.
Reducing stigma and discrimination has been a priority in many national mental health policies for decades. Focusing efforts requires us to understand where this has the greatest impact on people with mental health problems. In 2024, we conducted a nationally representative survey that aimed to assess the burden of discrimination (as a product of frequency and impacts of experiences). Secondary aims were to quantify the types of discrimination experienced in different life domains and the sociodemographic and mental health problem characteristics of those experiencing higher burden.
Methods
Online surveys were completed by 6032 members of the general Australian community aged 18 years and over. The survey was carried out by the survey company The Social Research Centre, using their Life in Australia™ probability-based panel. Those who reported a mental health problem or scored high on the Kessler 6 measure of psychological distress (n = 2613) were asked about the past 12-month frequency and impact of their experiences of discrimination in a broad range of settings, including family, friends, workplaces and health services. The data were initially analysed using percent frequencies and 95% confidence intervals. A burden score was calculated for each domain, incorporating frequency and impact among those who reported discrimination experiences.
Results
Overall, discrimination in social life was the most common (43.6% [95% CI 41.2, 45.9]), followed by discrimination from family (41.4% [95% CI 39.1, 43.7]) or in making or keeping friends (41.0% [95% CI 38.7, 43.3]). However, the highest burden was from discrimination in finding or keeping a job, in dating/intimate relationships, in housing (including renting or public housing) and in obtaining welfare benefits or disability pensions. The most common type of discrimination experience in the workplace and among friends, family and partners was of people lacking understanding of the impact of the person’s mental health problem. People aged 35–64 years were more likely than those aged 18–34 years to report higher burden in multiple domains; people with depression or attention-deficit/hyperactivity disorder also reported burden in more domains than people with anxiety or severe mental health conditions. Overall, 67.7% (95% CI 65.5, 69.9) agreed that stigma and discrimination was worse than the mental health problem itself.
Conclusions
Our study suggests that reducing the frequency and impact of discrimination in workplaces, welfare benefits and housing should be key targets for policy and practice. Improving the capacity of people in workplaces and intimate partners, families and friendship groups to better understand the impacts of mental health problems on individuals should also be a priority.
Technological similarity enables wine operators to share best practices, benchmark against industry standards, and identify new areas of innovation. Despite this, measuring similarity is notoriously challenging. In this paper, I use sentence embeddings on wine patent data to show how similarity compares across different models. I validate the results both internally and externally, showing large discrepancies in annual trends. The results underscore the importance of selecting suitable models for market assessment, providing a valuable primer for both wine operators and technologists.
On June 19, 2024, the Anti-Money Laundering Regulation (“AMLR”), the Regulation establishing the Anti-Money Laundering Authority (“AMLAR”), and the Sixth Anti-Money Laundering Directive (“AMLD6”) were published in the Official Journal of the EU, signaling a significant shift in the institutional and substantive architecture of anti-money laundering (“AML”) frameworks within the Union. More than simply enhancing existing rules, the new regime introduces innovative solutions to address persistent deficiencies in previous AML/CFT frameworks, particularly the fragmentation across Member States. A notable innovation is the extension of the AML regulatory framework to the professional football sector, which has become increasingly vulnerable to illicit financial activity due to its complex organisation, large financial flows and opaque ownership structures. As a result, professional football clubs and football agents are now subject to AML requirements, including customer due diligence, transaction monitoring and reporting suspicious transactions. This article examines the recently introduced AML obligations for the football sector, navigating the complex regulatory framework and mapping out the underlying requirements. The aim is to increase awareness and understanding of these obligations, thereby aiding football clubs and agents in complying with them and ensuring the integrity of the European football industry.
This article examines attitudes to the law in Menander. It argues that the law is given a specifically Athenian context and that it can give us an insight into the concerns and values of the playwright and his society. By analysing the ways in which characters perceive issues of legality, the article stresses the importance of humanity and personal character in the plays’ dramatization of the interface between private lives and public institutions in early Hellenistic Athens. The article highlights how the ambivalence and the multivocality which are inherent in Menander’s dramatic technique allow for varying responses and for the presentation of radical views.
This article examines how donor requirements affect Civil Society Organisations’ execution of foreign aid initiatives, comparing core and project funding mechanisms in development cooperation. Through a structured, focused comparison of two Latin American CSOs receiving funding from the Swedish International Development Cooperation Agency (SIDA), the research reveals that core funding, contrary to prevailing theories, has a more detrimental impact than project funding due to the nature, timing, and cost of its associated requirements. The analysis identifies variations in stakeholder impact across the aid chain, with intermediary organisations playing significant roles. The findings challenge assumptions about core funding's empowering effects, highlighting how multiple layers of requirements can impede operational effectiveness. The study contributes to scholarly understanding of donor-recipient dynamics while offering practical insights for improving aid delivery mechanisms. It suggests that enhancing aid effectiveness requires not merely simplified requirements, but a fundamental reconsideration of how donors structure their relationships with implementing CSOs.
The present study experimentally investigates the onset of ventilation of surface-piercing hydrofoils. Under steady-state conditions, the depth-based Froude number $\textit{Fr}$ and the angle of attack $\alpha$ define regions in which distinct flow regimes are either locally or globally stable. To map the boundary between these stability regions, the parameter space $(\alpha , \textit{Fr})$ was systematically surveyed by increasing $\alpha$ until the onset of ventilation while maintaining a constant $\textit{Fr}$. Two simplified model hydrofoils were examined: a semi-ogive with a blunt trailing edge and a modified NACA 0010-34. Tests were conducted in a towing tank under quasi-steady-state conditions for aspect ratios of $1.0$ and $1.5$, and for $\textit{Fr}$ ranging from $0.5$ to $2.5$. Ventilation occurred spontaneously for all test conditions as $\alpha$ increased. Three distinct trigger mechanisms were identified: nose, tail and base ventilation. Nose ventilation is prevalent at $\textit{Fr} \lt 1.0$ and $\textit{Fr} \lt 1.25$ for aspect ratios of $1.0$ and $1.5$, respectively, and is associated with an increase in the inception angle of attack. Tail ventilation becomes prevalent at higher $\textit{Fr}$, and the inception angle of attack exhibits a negative trend. Base ventilation was only observed for the semi-ogive profile, but it did not lead to the development of a stable ventilated cavity. Notably, the measurements indicate that the boundary between bistable and globally stable regions is not uniform and extends to significantly higher $\alpha$ than previously estimated. A revised stability map is proposed to reconcile previously published and current data, demonstrating how two alternative paths to a steady-state condition can lead to different flow regimes.
