- Use-wear analysis shows changing handaxe grip and use across time at la noira (France)Publication . Rodriguez, Alice; Coco, Emily; Moncel, Marie-Hélène; Despriée, Jackie; Hardy, Bruce; Iovita, RaduHandaxes — sub-oval bifacially flaked stone tools — were produced for over a million years across Africa, Europe, and Asia during the Lower Palaeolithic. Their relatively uniform shape across varied environments and over a million years raises the question of whether or not their function and purposes were also uniform. Previous studies suggested that handaxe shape might be related to patterns in use and maintenance, but the level of analysis may have been too coarse to tease out specific uses. This study investigates the function of handaxes from two successive Acheulean occupations at the la Noira site (France), separated by ca. 200 ka. This research aimed to find out how hominins generally used handaxes through microscopic use wear analysis. Specifically, we documented macro-wear characteristics such as type (micro-scars, edge crushing, striations, edge rounding, polish), and their relative position and distribution. We used a Geographic Information System (GIS) to translate these observations into wear location heatmaps — visual representations highlighting areas of intense or repeated use — and compared these across different occupation periods. The analysis revealed that similar handaxes were likely held in different ways and used for different tasks during the two phases of occupation at la Noira, at 700 ka and respectively 450 ka. These findings suggest a more complex scenario of handaxe use than previously understood, including changes in tool use modalities over time that reflect changes in handaxe function and hominin technical behaviors.
- The interaction of accounting employability-based skills and problem-based learningPublication . Arianpoor, Arash; ABDOLLAHI, AHMADPurpose – Thisstudy aims to provide a framework for the interaction between accounting employability-based skills and problem-based learning (PBL). Design/methodology/approach – This study explored the views of 18 participants (11 accounting professors and seven board members) who were chosen as experts. Thisstudy collected data through two consecutive stages (i.e., interviews and questionnaires) in 2024. After summarizing the opinions of the six interviewees, the 31 accounting employability-based skills in interaction with PBL were classified into three groups: technical, soft, and social mobility skills. A questionnaire survey was conducted in the second stage of the study. The opinions of 18 accounting professors and board members of the firms were surveyed using the Delphi method. Findings – This study employed Kendall’s Coefficient of Concordance (W) to assess agreement among 18 experts in ranking 31 accounting skills across three primary constructs: Technical Skills (TES), Soft Skills (SOK), and Social Skills (SMK). The results demonstrated a strong agreement among experts in prioritizing these skills. The Consensus Index (CI) values align with other reported model metrics, suggesting that respondents largely agreed on the relevance and clarity of the items within each construct. The results showed thatsoftskillssuch as adaptability; knowledge of different contexts; preparing forthe unpredictable nature ofthe accounting field; adapting quickly to new tools, processes, and market conditions; maintaining their effectiveness in a dynamic environment; and engaging in discussions and presenting findings during PBL activities are among the top 10 skills. The other statistical analyses conducted in this study further supported these results. Research limitations/implications – Despite the valuable insights generated by this study, several limitations must be acknowledged. The study was conducted in a specific national and cultural context (e.g., within an emerging economy), which may limit the generalizability of the findings to other regions with different educational, economic, or regulatory environments. Future cross-country comparisons are recommended to enhance the external validity of these findings. Expert opinion was sought in this study. Specialists and professionals were selected for this study. However, because the combination of accounting skills and PBL is a relatively recent development in accounting, we were unable to confirm the effectiveness of PBL through interviews or questionnaires. In future studies, it would be beneficial to collect feedback from real users to determine the benefits of PBL in accounting as well as the specific circumstances in which it is effective. Although this study provides meaningful understanding, its small sample size (n 5 18) restricts the generalizability of its findings to larger populations. The Delphi panel and survey respondents were primarily academic and professional stakeholders with accounting education experience. Although these insights are essential, the exclusion of students and recent graduates may limit the diversity of their perspectives on employability-related challenges and competencies. Although validated scales were employed for the TES, SOK, SMK, and PBL, the cross-sectional nature ofthe study limited the ability to draw causal inferences. Future studies should employ longitudinal research to track changes in employability skill development over time, particularly in response to curriculum redesigns or sustained PBL interventions. Moreover, as accounting employability is crucial in post-higher education, future studies should explore ways to translate more implications from “university” to the “accounting profession.” While PBL was conceptualized as a mediating construct, this study did not explore its multiple formats (e.g., case-based, simulation-based, and online PBL). These design variations may influence the acquisition of employability skills differently and merit separate investigation. Combining quantitative modeling with qualitative data, such as classroom observations, could offer deeper insights into how students internalize employability skills through PBL experiences. The study revealed that awareness of blockchain technology in accounting, especially in areas such as auditing and transaction verification (TES11), is among the top ten skills. Future research should explore how AI-driven or gamified PBL platformsinfluence skill acquisition and employability in response to increasing integration of AI into educational and accounting work environments. Practical implications – These findings offer critical insights to curriculum designers and educators. Accounting departments should restructure their learning environments to embed PBL not as a supplemental tool but as an integral design framework to nurture strategic thinking, self-regulated learning, and communication competencies. Institutions in emerging and developing economies, where employability gaps are often pronounced, can leverage PBL to contextualize global skill standards within local educational practices. By aligning skill development with real-world simulations and reflective learning, universities can equip students with the evolving demands for accounting roles. Universities can apply these results to revise their accounting education and teaching approaches to professional accountants, thereby enhancing their competitive edge and developing effective marketing plans, particularly for international accounting students. Employers and industry partners are encouraged to collaborate with academic institutions to co-design PBL modules that reflect workplace complexity. Managers should consider applicants’ experience with applied learning models, such as PBL, as a strong predictor of workplace readiness, particularly in areas that require adaptive reasoning, critical problem-solving, and stakeholder engagement. Continuous upskilling initiatives within accounting firms can adopt PBL-based workshops to close the competency gap between the staff members. As board members’ opinions were also considered in this study, their views on accounting employability-based skills were also considered. Accounting professors can strategise ways to enhance students’ skills and create plans to facilitate the job search process for accounting students. National and institutional education policy frameworks should promote outcome-based learning standards that explicitly integrate employability and skill metrics into course assessment. Policymakers in higher education ministries may consider incentivizing curriculum redesign to support PBL strategies in professional programs such as accounting, finance, and auditing. Incorporating PBL into accounting education is shifting towards a hands-on learning environment. This study promotes interactive learning by addressing complicated practical problems and developing necessary skills in the accounting field. The aim was to produce skilled graduates who could apply their knowledge in real-world situations. This helps to meet the needs of the current workforce, which involves adjusting, creating, and collaborating. Originality/value – The combination of employability-based skills and PBL in accounting education forms a strong foundation for equipping graduates in the job market. There is currently a gap in that PBL may not cover all skills necessary for successful accounting employment. Therefore, this study examines the interaction between these two fields, which has not been explored previously.
- Antígona na escola. Personagens femininas da antiguidade no teatro didático de Ana Cristina OliveiraPublication . Nogueira, Adriana; Morais, Carlos; Brasete, Maria Fernanda; Ferreira, António Manuel; Mancelos, João deNeste artigo, procuro responder a algumas perguntas que me foram suscitadas pelo trabalho que Ana Cristina Oliveira (professora de Filosofia, dramaturga, encenadora e atriz) tem vindo a desenvolver no grupo de teatro escolar, por si fundado, Tapete Mágico, no que respeita à escolha das personagens femininas da antiguidade nas peças que escreve para – e com – os alunos. Pretendo perceber qual a receção que a antiguidade tem entre os mais jovens, como se podem relacionar as temáticas de peças de tragediógrafos gregos com as preocupações da juventude atual; e qual a atualidade dessas questões e que outras interrogações levantam.
- Grazer‐induced bioluminescence and toxicity in marine dinoflagellatesPublication . Gonzalo‐Valmala, Paula; Pourdanandeh, Milad; Lage, Sandra; Selander, ErikMarine copepods are the most abundant multicellular zooplankton in the global oceans. They imprint their surrounding waters with a unique bouquet of chemical compounds, including polar lipids such as copepodamides. Prey organisms can detect copepodamides and respond by inducing defensive traits including bioluminescence, toxin production, changes in colony size, and structural modifications. This mechanism has been suggested to contribute to harmful algal bloom formation, but to date only a limited number of species and strains have been experimentally exposed to copepodamides. Here, we quantify bioluminescence and toxin content in response to increasing concentrations of copepodamides in three harmful algal bloom-forming species of marine dinoflagellates: Alexandrium catenella, Protoceratium reticulatum, and Gymnodinium catenatum. All three species up-regulated their defensive traits in response to copepodamide exposure, including the first example of copepodamide-induced GC-toxin production. Neither bioluminescence nor toxin production was associated with measurable costs in terms of reduced growth rates. The results support the role of copepodamides as general alarm cues in marine phytoplankton. Moreover, the expression of simultaneous defensive traits may confound studies addressing the costs and benefits of these co-varying traits.
