Many archaeology graduate students pursue advanced degrees in the hope of undertaking an academic career. Job-listing websites often serve as the first port-of-call for students seeking academic positions. We examined tenure-track job advertisements over the past decade to gain insights into the academic job market for archaeologists. Using data from the community-edited Academic Jobs Wiki for Archaeology, we examined changes in the academic job market over time. We investigated the editing dynamics of the Wiki to understand its users and their biases. We then analyzed the text of 431 job ads posted from 2013 to 2023. Our analysis addresses the question of how archaeological topics, methods, and geographic regions specified in archaeological job ads have shifted over time. We also explored whether the labor burden for applicants has changed over time: do institutions request more information and documents from applicants at the initial stages of application, compared to a decade ago? Finally, we assessed the influence of sociopolitical factors on the changing focus of research topics in the field. We conclude with implications for archaeology students, graduates, and advisors seeking to understand the dynamics of the academic job market and the requirements of employers.

La reciente excavación arqueológica efectuada en el centro provincial inka de Tambo Viejo, en el valle de Acarí, Perú, resultó en el hallazgo de una pequeña construcción de forma rectangular y semisubterránea. En su interior encontramos hojas y semillas de coca en asociación con arena limpia. Esta evidencia sugiere que la pequeña construcción sirvió para el almacenamiento de las hojas de coca, las que habían sido cubiertas con arena limpia para garantizar su preservación. La arena tiene propiedades térmicas que crean condiciones relativamente frías y que son óptimas para la preservación de productos orgánicos.

This study investigates the effect of participation in the Global Value Chain (GVC) on Multidimensional Energy Poverty (MEPI), and the role played by the quality of institutions (QI) in the short and long run for 51 African countries over the period 1995–2018. For this purpose, the DCCE-PMG approach is employed, as well as both the GVC and QI indices. MEPI includes electricity, clean fuel, and technology for cooking. The findings show that GVC participation negatively affects MEPI in both the short and long run, meaning that the GVC reduces energy poverty in Africa. Besides, there is mixed evidence regarding the heterogeneity effect according to rural and urban locations. The evidence further shows that GVCs interact with institutions to negatively impact both energy poverty and the rural–urban MEPI gap, implying that the better the institutional quality, the larger the effect of GVC integration on energy poverty reduction. Therefore, a better quality of institution enables local firms, participating in the GVC, to easily capture technology and knowledge diffusion to promote energy development and fulfill the spatial inequality in energy poverty. Additional tests allow us to confirm the evidence and, moving forward, the implications of participation in the GVC.

This essay on Ernest Weinrib’s Reciprocal Freedom argues that his conceptions of correlativity and systematicity are at odds. Correlativity as he conceives it is inexplicably all-encompassing; it does not track the complexity of interpersonal fairness in either morality or law. Correlativity can be understood as a formal constraint or as a requirement of mutual justification. We do not have reason to treat it as the animating principle that shapes private law. Weinrib’s own concept of systematicity helps us to see why a system of private law that is oriented primarily to vindicating correlativity will always come up short. Systematicity requires that private law work in harmony with the rest of the legal system to promote the principles of justice to which our political community is committed. Systematicity is more demanding than Weinrib allows. The ex post and ad hoc process by which private right is acclimated to public right, in Weinrib’s account, will not suffice to realize systematicity.

Geopolitical tensions escalated between the USSR and the Republic of China over control of the Chinese Eastern Railway during the late 1920s, resulting in a brief war in which several thousand people were killed. Given the violence in Manchuria in the months preceding direct military engagement, it is surprising that Soviet authorities sent an opera tour to the zone of conflict. This article examines the two seasons spent by visiting Soviet opera vocalists at the Railway Assembly Hall (Zhelsob) from September 1927 to February 1929, attending to the staging, reception and political goals of the tour. I argue that the opera stage in the city of Harbin transformed into a temporary zone of informal extraterritoriality, where unpredictable collaborations transpired between ideological enemies on either side of the military clash. The Soviet opera tour to Manchuria prompts us to reconsider the agency and intentionality of musicians in armed conflict.

This position statement provides guidelines for health professionals who are considering online or direct-to-consumer genetic testing for their patients. It presents the major issues around online and direct-to-consumer (DTC) testing including how it is accessed, motivations for accessing testing and how to return these results. Online or DTC recommendations include: (1) DTC testing should only be done by individuals/consumers who are well informed, aware of the risks, benefits and limitations of testing, and able to consent for their DNA to be collected, analyzed and potentially stored. Where possible, individuals/consumers should also be aware of the alternative option of undertaking testing through healthcare professionals in a clinical context, and the benefits of this. (2) Decisions about having a child tested should be based on peer-reviewed, published evidence. Genomics testing for children should be within a clinical context where parents are informed, have access to clinical support and professional genetic counseling about this decision, as well as support for the range of results received. (3) Parents considering direct-to-consumer testing on their newborn are counselled, or given information, to encourage them to have standard government funded newborn bloodspot screening testing on their newborn. (4) When choosing an online genomic test, preference should be given to tests undertaken in accredited laboratories offering tests accredited with the Therapeutic Goods Administration. (5) Results obtained through methods other than direct analysis from a laboratory accredited to perform genomic testing to inform human health and wellbeing should be interpreted with caution. The HGSA recommends that such results must be confirmed in an accredited diagnostic laboratory prior to relying on them to inform options for treatment, surveillance or risk reduction, or before undertaking cascade testing in family members. (6) When individuals are concerned about their health, they should consult an appropriate healthcare professional to decide whether an online genomic test is appropriate and discuss how useful test results could be to make health-related decisions.

A ceftriaxone safety alert prompted a review of rapid response and cardiac arrest events in relation to the timing of intravenous cephalosporin administrations across a large health system. Despite high utilization, we found a low rate of significant ceftriaxone-related adverse events with a similar incidence as other intravenous cephalosporins.

The accuracy, robustness and affordability of localisation are fundamental to autonomous robotic inspection within aircraft maintenance, repair and overhaul (MRO) hangars. Hangars typically have high ceilings and are predominantly steel-framed structures with metal cladding. Because of this, they are regarded as GPS-denied environments, characterised by significant multipath effects and strict operational constraints, which together form a unique challenging setting. The lack of comparative techno-economic benchmarks for localisation technologies in such environments remains a critical gap. Addressing this, the paper presents the first techno-economic analysis that benchmarks motion capture (MoCap), ultra-wideband (UWB) and a ceiling-mounted camera (CMC) system across three operational scenarios: robot localisation, asset monitoring and surface defect detection within a single-bay hangar. A two-stage optimisation framework for camera selection and placement is introduced, which couples market-based camera-lens selection with an optimisation solver, producing camera layouts that minimise hardware while meeting accuracy and coverage targets. The consolidated blueprints provide quantification of the required equipment and its performance: 15 global-shutter GigE cameras are adequate for drone localisation, 9 cameras meet the requirements for on-bay monitoring and 49 high-resolution cameras facilitate defect mapping of the upper airframe surfaces for midsize defects. Across these scenarios, the study reports indicative performance and cost envelopes: a MoCap installation delivers submillimeter localisation at an estimated £190k per bay, UWB delivers centimetre-level tracking for around £49k and the proposed CMC system layouts achieve task-specific coverage with costs in the £9k–£77k range. The analysis equips MRO planners with an actionable method to balance accuracy, coverage and budget, demonstrating that an optimised CMC system can deliver robust and cost-effective sensing for next-generation smart hangars.

We show that a very general hypersurface of degree $d \geq 4$ and dimension $N \leq (d+1)2^{d-4}$ over a field of characteristic $\neq 2$ does not admit a decomposition of the diagonal; hence, it is neither stably nor retract rational, nor $\mathbb {A}^1$-connected. Similar results hold in characteristic $2$ under a slightly weaker degree bound. This improves earlier results in [44] and [33].

Although many online-based dietary surveys have been developed in recent years, systems that easily survey the dietary balance based on the Japanese diet are insufficient. This study aimed to evaluate the relationship between dietary balance scores from an online survey system based on the Japanese Food Guide Spinning Top, and nutrient/food intake calculated using the weighing method from dietary records (DRs), as well as to assess the system’s utility and applicability. An online dietary balance survey and semi-weighted DR assessment with food photographs were conducted in Japanese participants (n = 34). Registered dietitians entered the balance scores into the system based on the participants’ food photographs, and the scores were calculated using the system. Significant positive correlations (p < 0.001) were found between the online dietary balance scores and nutrient/food intake from DRs; especially for ‘grain dishes’ and carbohydrates (r = 0.704); ‘vegetable dishes’ and the vegetable dish group (sum of potatoes, vegetables, mushrooms, and algae) (r = 0.774); ‘main dishes’ and protein (r = 0.661); ‘milk’ and the milk and milk products group (r = 0.744); and ‘fruits’ and the fruits group (r = 0.748). Bland–Altman analysis showed that the dietary balance scores obtained by this system tended to underestimate the intake compared with the weighing method. Although there are limitations to the accurate estimation of nutrient and food intake, the online dietary balance scores obtained from the online dietary balance survey system were useful for understanding the dietary balance in the Japanese diet.

Herbicide resistance poses a significant challenge due to the increasing number of weeds resistant to multiple sites of action (SOAs). Recently, smooth pigweed populations resistant to glyphosate have been confirmed in the KwaZulu-Natal Province in the Republic of South Africa (RSA). This study evaluated herbicide products with different SOAs to provide alternative options for controlling glyphosate-resistant (GR) smooth pigweed populations. Dose-response assays for preemergence and postemergence herbicides were conducted under glasshouse conditions at the University of Pretoria, RSA. Seeds of GR smooth pigweed populations from Bergville and Winterton, and a glyphosate-susceptible (GS) population from Hendrina, were used. For the evaluation of preemergence herbicides (mesotrione, atrazine, imazethapyr, and acetochlor), seeds were sown in pots and herbicides were applied 12 hours after sowing. Postemergence herbicides (mesotrione, atrazine, tembotrione and atrazine tank mixture, and chlorimuron-ethyl) were tested on potted plants at the 6-leaf stage. Herbicides were applied at 0×, 0.5×, 1×, 2×, and 4×, where × is the recommended field rate for the herbicide products representing each SOA. Preemergence herbicides provided greater than 90% control across all populations. For postemergence herbicides, mesotrione effectively controlled all the GR populations, whereas the GS population from Hendrina exhibited reduced sensitivity (>50% survival). Atrazine was effective at rates higher than the recommended field rate in the GR populations. The tank mixture of tembotrione and atrazine had an additive effect compared to the sole application of mesotrione and atrazine. Chlorimuron-ethyl was only effective on the GS population. These results suggest that incorporating effective preemergence and postemergence herbicides into weed management programs could improve control of GR populations of smooth pigweed.

This study investigated the effect of group size on tail damage and growth performance in growing-finishing pigs with intact tails. A total of 432 pigs were housed indoors on fully-slatted floors and assigned to either small (nine pigs per pen) or large (18 pigs per pen) groups, with equal space and resource allocation per pig. No environmental enrichment was provided. From nine to 23 weeks of age, pigs were monitored weekly for tail injuries using a 5-point scale (0 = no injury, 4 = partial or total loss). The most severe score observed during each four-week period was used for analysis, and outbreaks were defined as the occurrence of one or more pigs per pen with a tail score ≥ 2. Group size did not influence average daily gain, feed intake, or feed to gain ratio. However, pigs housed in small groups experienced more frequent and severe tail injuries, including a higher proportion of removals due to tail wounds. In contrast, pigs in large groups were more likely to receive healed tail scores (score 1) or mild injuries (score 2), and experienced fewer removals. While these results suggest that tail damage may be less severe in larger groups, the total number of pigs affected by tail biting was similar across treatments. These findings highlight the importance of managing tail-damage severity and suggest that group size can influence welfare outcomes in systems where pigs are raised with intact tails.
