The Acholla Archaeological Project is an international collaboration at the site of Acholla (Tunisia) between the Institut National du Patrimoine (INP), Dickinson College and the University of Oklahoma, with additional support from the University of Leicester and the Endangered Archaeology in the Middle East and North Africa (EAMENA) project. The first season of the project took place in June 2025, focusing on three main tasks: fieldwalking, topographic survey and architectural documentation. Over a period of two and a half weeks, an area of over 25 ha was covered by a fieldwalking team and nearly 40,000 finds were collected for study and analysis. Topographic and architectural surveys were also undertaken to begin the process of creating an updated plan of the site. The work accomplished this season has already yielded new information about Acholla and has provided a strong foundation for future fieldwork campaigns and further research at this important coastal site.

Seabirds are excellent ecosystem indicators and are amongst the most threatened taxa globally. Aldabra Atoll, Seychelles, supports significant breeding colonies of seabirds, especially red-footed boobies Sula sula. The population was surveyed by boat during 1968–1969 and in 2000, over which period the population grew from c. 6,500 to 10,000 breeding pairs. In 2022–2023, we monitored five subcolonies across Aldabra to determine breeding phenology and breeding success. In August 2022 and February 2023, we surveyed the atoll-wide population using the boat-based survey methodology followed in earlier studies. We also carried out unmanned aerial vehicle (UAV) surveys in February 2023 to compare the results with the boat-based counts and to quantify inland colonies undetectable by boat. Boat surveys revealed that Aldabra’s red-footed booby population had grown to 36,720 pairs by 2023, an increase that is intrinsically possible based on our population model but only if the much lower count in 2000 was an underestimate. The UAV and boat counts were closely aligned in our study, and aerial images captured a similar number of nests to boat surveys for shoreline colonies. However, UAV surveys revealed several undocumented inland colonies. An additional 5,574 inland breeding pairs of red-footed boobies were counted from images captured inland during aerial surveys in the 2023 wet season, bringing the atoll-wide population to at least 45,817 pairs. We recommend UAVs for surveys of large, conspicuous seabird species at low-lying mangrove colonies. Our study highlights the global importance of Aldabra as the most significant red-footed booby colony in the Indian Ocean and possibly the world.

Recent studies on Street-Level Bureaucracy (SLB) have diversified significantly, especially following Brodkin’s 2011 call to include non-public actors in analyses of public policy implementation. Discretion remains central, often framed as a source of tension between management and workers, particularly in light of new organizational practices such as accountability and digitization. This paper shifts the focus from individual perspectives to examine discretion as an organizationally embedded phenomenon. Based on a study of 72 social workers in various public and third-sector organizations in Rome (Italy), this research explores SLBs’ discretion within contemporary, pluralistic contexts, thereby allowing for a nuanced examination of the relationships between organizational frameworks, working conditions, and public service delivery. The findings presented here underscore a strong “organizational effect” in shaping how discretion is perceived and practiced by the interviewees. This organizational effect suggests that discretion is deeply embedded in the specific institutional settings and cultural contexts in which SLBs operate.

This guide provides a philosophical framework and practical advice for gathering, analyzing, and reporting a particular type of qualitative data. These data are obtained from including an open-text box following the key quantitative question in survey-style studies with the request to ‘Please explain your response’. While many studies currently collect such data, they often either fail to report or analyze it, or they conduct unstructured analyses with limited detail, often mistakenly referring to it as ‘thematic analysis’. Content analysis provides a well-established framework for analyzing such data, and the simplicity of the data form allows for a highly pragmatic and flexible approach. The guide integrates the concept of reflexivity from qualitative research to navigate the large number of researcher degrees of freedom involved in the process, particularly in working with the second coder. It begins by arguing for the value of this data, before outlining the guide’s philosophy, offering advice on maximizing the validity of your data, and addressing the common concern of confabulation. It then provides advice on developing a coding scheme, recruiting and collaborating with a second coder, and writing your report, considering the potential role of large language models at these various stages. Additionally, it provides a checklist for reviewers to evaluate the quality of a given analysis. Throughout the guide, a running example is used to demonstrate the implementation of the provided advice, accompanied by extensive example materials in the online repository, which can be used to practice the method.

Despite lying at a crossroad of Pleistocene hominin dispersals, little is known about human occupation in Iraq during this period. An archaeological survey in the Western Desert is revealing recurrent hominin activity at Shbicha, highlighting the region’s potential in advancing our understanding of hominin behaviour and dispersal across South-west Asia.

Qualitative research addresses important healthcare questions, including patients’ experiences with interventions. Qualitative evidence syntheses combine findings from individual studies and are increasingly used to inform health guidelines. However, dissemination bias—selective non-dissemination of studies or findings—may distort the body of evidence. This study examined reasons for the non-dissemination of qualitative studies. We identified conference abstracts reporting qualitative, health-related studies. We invited authors to answer a survey containing quantitative and qualitative questions. We performed descriptive analyses on the quantitative data and inductive thematic analysis on the qualitative data. Most of the 142 respondents were female, established researchers. About a third reported that their study had not been published in full after their conference presentation. The main reasons were time constraints, career changes, and a lack of interest. Few indicated non-publication due to the nature of the study findings. Decisions not to publish were largely made by author teams. Half of the 72% who published their study reported that all findings were included in the publication. This study highlights researchers’ reasons for non-dissemination of qualitative research. One-third of studies presented as conference abstracts remained unpublished, but non-dissemination was rarely linked to the study findings. Further research is needed to understand the systematic non-dissemination of qualitative studies.

An intensive archaeological surface survey of the El Argar site and its hinterland has provided new information for the discussion of early sociopolitical complexity in the western Mediterranean. This article presents the preliminary interpretation of a long-term settlement pattern, particularly in the Bronze Age.

The present study examines the influence of non-economic factors on women’s labour market participation in low-income neighbourhoods of urban areas in India. For this purpose, we conducted a survey in two slum areas of Kolkata city in West Bengal – one, located in a residential neighbourhood, and another, situated in the dock area of the city and surrounded by factories. Our survey of 384 ever-married working-age women makes three noteworthy observations. First, the location of slums crucially affects the type of paid work that is available and accessible to women. Secondly, although women’s entry into the labour market maybe crisis-driven, the women workers develop an intrinsic valuation of paid work as their right, and as a means of livelihood in the process. Finally, social and community norms explain both the non-participation and the temporary withdrawal of women from the labour force. Thus, the inability and/or the unwillingness of slum women to participate in the labour market primarily stem from the strict adherence to patriarchal norms in general, and community norms in particular, either imposed on them directly by their spouses or indirectly by the community they reside in. Therefore, our analysis highlights the need for tailor-made policies that meet locality-specific needs.

Anonymous online surveys using financial incentives are an essential tool for understanding sexual networks and risk factors including attitudes, sexual behaviors, and practices. However, these surveys are vulnerable to bots attempting to exploit the incentive. We deployed an in-person, limited audience survey via QR code at select locations in North Carolina to assess geolocation application use among men who have sex with men to characterize the role of app usage on infection risk and behavior. The survey was unexpectedly posted on a social media platform and went viral. Descriptive statistics were performed on repeat responses, free-text length, and demographic consistency. Between August 2022 and March 2023, we received 4,709 responses. Only 13 responses were recorded over a 6-month period until a sharp spike occurred: over 500 responses were recorded in a single hour and over 2,000 in a single day. Although free-text responses were often remarkably sophisticated, many multiple-choice responses were internally inconsistent. To protect data quality, all online surveys must incorporate defensive techniques such as response time validation, logic checks, and IP screening. With the rise of large language models, bot attacks with sophisticated responses to open-ended questions pose a growing threat to the integrity of research studies.

Limited research has explored the delivery of sustainable design in higher education globally. Therefore, the aim of this paper is to investigate educational practices on the topic. Through an online survey, we investigated numerous aspects of units of study exposing topics related to sustainable design with a focus on contents, teaching methods and educational objectives. The survey was accessed by almost 400 educators in the field of sustainable design. The data show that a variety of teaching methods are used, with a critical role played by project-based learning in addition to traditional lectures. Most respondents rated all investigated intended learning outcomes as relevant or very relevant. In terms of contents and methods treated by the respondents, product eco-design and design for X are the most frequently taught methods. Educational approaches and teaching objectives are poorly affected by the discipline of the degree in which units of study are taught. In terms of contents, design degrees include approaches to sustainable design at the spatio-social level more frequently than engineering degrees do.

Recent reports suggest that New Zealanders underestimate the burden of non-communicable diseases (NCDs) on society, perceiving NCDs as standalone problems to be managed by affected individuals. This belief conflicts with the Developmental Origins of Health and Disease (DOHaD) hypothesis that NCD risk is rooted in early-life environmental exposures. For the research community to contribute towards shifting societal beliefs, we need to know more about NZers’ understanding of how NCDs develop and have the potential to track this over time. To address this, we conducted a face-to-face survey of 702 Auckland adults in 2015–16, repeated in 2022–23 with 814 online and 96 face-to-face respondents. An increased recognition of links between mental health and obesity was the only change observed between the earlier and later cohorts. Overall, of the 59% familiar with the term ‘non-communicable disease’, 73% accurately described NCD characteristics and gave examples. Online, tertiary-educated and non-male respondents were more likely to identify various social determinants of health in addition to individual behaviours as contributors to metabolic disease risk. More than twice as many subjects strongly agreed that preconception health of mothers could affect the health of the child than that of fathers. Maternal nutrition was recognised by most as important for fetal health, but 49% disagreed or did not know if it could affect adult health. These results indicate that regardless of subject sampling or data collection method, adult New Zealanders have little appreciation of the significance of the early-life environment in relation to NCD risk across the lifespan.

During the 2019 growing season, seeds of Palmer amaranth and common waterhemp were collected from 141 and 133 agricultural sites, respectively, from across the southeastern and midwestern United States. These accessions were screened with a new protoporphyrinogen oxidase (PPO) inhibitor, epyrifenacil, using a whole-plant bioassay at 20 g ai ha−1 in controlled environmental conditions to estimate its efficacy on these two agronomically important weeds. In addition, the coding sequence of the PPX2 gene was determined for plants from each accession through short-read sequencing of cDNA fragments amplified via polymerase chain reaction. Results showed that nearly all accessions were completely controlled by epyrifenacil, with average survival rates of less than 2% for both species. Target site resistance mutations toward PPO inhibitors were lower in Palmer amaranth (<20%) compared to waterhemp, with nearly half of all waterhemp samples (42%) possessing the ΔG210 allele, which is shown to cause high-level resistance to other commercially available PPO-inhibiting herbicides. Follow-up testing of accessions with high frequency (≥50%) of the ΔG210 allele of PPX2 compared the efficacy of epyrifenacil, saflufenacil, and saflufenacil + trifludimoxazin and showed that of the herbicides tested, epyrifenacil at 20 g ha−1 provided the best control, averaging 85% mortality across these accessions. Same-plant association study of molecular data and whole-plant assay correlated all detected variants of PPX2 with visual injury following epyrifenacil treatment and found that the ΔG210 mutation was associated with a reduction in relative efficacy of epyrifenacil in some accessions. All other known target site resistance mutations appeared to have no significant effect on epyrifenacil efficacy.

China is well known for providing official data, but how to treat these data is a longstanding debate among China scholars. This paper advances understandings of how to interpret Chinese official statistics about the internet. Using standards for evaluating surveys in the social sciences, we systematically compare official data from the China Network Information Center (CNNIC), which is under the supervision of China’s main regulator of internet policy, with the China Internet Survey 2018 (CIS), which is, to our knowledge, the first nationally representative survey on internet use in China. Using three examples, we illustrate how methodological differences in sampling design and measurement can lead to vastly different conclusions about key indicators of internet use in mainland China, including the percentage of internet users, their regional and urban–rural digital divide, and the percentage of specific social media platforms. We discuss the challenges of survey work on internet use in China and offer recommendations on how to interpret official statistics, especially in light of the limitations researchers face when conducting face-to-face surveys in China.
