Curated character of the Initial Upper Palaeolithic lithic artefact assemblages in Bacho Kiro Cave (Bulgaria).

The dispersal of Homo sapiens across Eurasia during MIS 3 in the Late Pleistocene is marked by technological shifts and other behavioral changes, known in the archaeological record under the term of Initial Upper Paleolithic (IUP). Bacho Kiro Cave in north Bulgaria, re-excavated by us from 2015 to 2021, is one of the reference sites for this phenomenon. The newly excavated lithic assemblages dated by radiocarbon between 45,040 and 43,280 cal BP and attributed to Homo sapiens encompass more than two thousand lithic artifacts. The lithics, primarily from Layer N1-I, exist amid diverse fauna remains, human fossils, pierced animal teeth pendants, and sediment with high organic content. This article focuses on the technological aspects of the IUP lithics, covering raw material origin and use-life, blank production, on-site knapping activities, re-flaking of lithic implements, and the state of retouched lithic components. We apply petrography for the identification of silicites and other used stones. We employ chaîne opératoire and reduction sequence approaches to profile the lithics techno-typologically and explore the lithic economy, particularly blade production methods, knapping techniques, and artifact curation. Raw material analysis reveals Lower Cretaceous flints from Ludogorie and Upper Cretaceous flints from the Danube region, up to 190 km and 130 km, respectively, from Bacho Kiro Cave, indicating long-distance mobility and finished products transport. Imported lithic implements, were a result of unidirectional and bidirectional non-Levallois laminar technology, likely of volumetric concept. Systematic on-anvil techniques (bipolar knapping) and tool segmentation indicate re-flaking and reshaping of lithic implements, reflecting on-site curation and multifaceted lithic economy. A limited comparison with other IUP sites reveals certain shared features and also regional variations. Bacho Kiro Cave significantly contributes to understanding the technological and behavioral evolution of early Homo sapiens in western Eurasia.

Industry visions of technology for older adults: A futures anthropology perspective.

The negative portrayal of ageing as a human decline burdening society has prompted Ageing Technology industries (AgeTech) to foresee solutions rooted in the Ageing in Place paradigm. These ostensibly neutral future interventions are intertwined with socio-technical dynamics. While Science and Technology Studies (STS) and anthropology scholars have questioned these AgeTech practices, limited literature explores industry's predictions of future AgeTech. Drawing on STS and futures-anthropology literature, I interrogate AgeTech industry visions of future assemblages involving older people, smart home technology, and socio-material discourses rooted in their own discrepancies and dilemmas. To unpack AgeTech futures, my methods include a review of 49 industry reports and 29 interviews with industry experts. Based on the reports, I designed comics to be used in interviews with experts spanning CEOs and managers of companies designing technology for older people, consultants, and aged-care workers based in 12 countries. Ageing futures are far from being neutral or a chronological process, instead they are non-consensual and fragmented. In the review and interviews, I captured future assemblages of a fragmented AgeTech industry in relationships with governments and industry giants. The fragmentation continues unfolding in participants from diverse countries and professions contesting dominant AgeTech narratives. In dissecting future assemblages, I also unpack non-consensual futures based on diverging experts' values (e.g. safety versus activity) and humans' values like control and improvisation challenging predictive and surveillance technology. AgeTech Futures transcend physical matters or assemblages of technologies and humans. They encompass future normativities, tensions, divergent values, and ideological concepts. I propose not only alternatives to the visions found in industry narratives, but also encourage scholars to understand the AgeTech industry's dilemmas.

Outdated and re-configured: Challenging linear conceptualizations of ageing through the case of revived obsolete technologies.

Taking as a starting point the conventional view of ageing as a linear process beginning in a youthful and productive stage but gradually deteriorating, this paper shifts the usual anthropocentric focal point towards technological artifacts which do not conform to this typical view. More specifically, three examples of technologies previously considered obsolete, but which have seen a revival in the last decade, are presented: the so-called dumbphones, analogue cameras, and vinyl players. Although very different at first glance, the three cases of these revived technologies show a similar evolution trajectory which breaks from the typical view of ageing in technological artifacts. Instead, they indicate how their revival does not simply entail a reconsideration of their initial value (such as it is often the case with antiques or heirlooms), but a transformation, hybridisation, and re-envisioned purpose. To this effect, the agential realism theory is applied to show how the revival of technological artifacts and practices once considered outdated attempts to dissolve binaries such as old/new, young/old, or slow/fast. Furthermore, such artifacts reveal trajectories of ageing that are unlike their human counterparts, but which can make way for new manners of articulating issues pertaining to ageing as a process in humans as well. The contribution of the paper lies in illustrating how adopting a non-linear view of ageing and fundamentally questioning its inherent binaries has the capacity to produce a much-needed nuanced view of ageing in humans, non-humans, and their sociomaterial entanglements.

Adhesive technology based on biomass tar documents engineering capabilities in the African Middle Stone Age.

The foragers of the southern African Middle Stone Age were among the first humans to adapt their environment and its resources to their needs. They heat-treated stone to alter its mechanical properties, transformed yellow colorants into red pigments and produced moldable adhesive substances from plants. Until now, only Podocarpus conifers have been identified as the botanical origin of Middle Stone Age adhesives. This is curious as these conifers do not produce sticky exudations that could be recognized as potential adhesives. To obtain an adhesive, tar must be made with a technical process based on fire. However, the nature of these technical processes has remained unknown, hampering our understanding of the meaning of this adhesive technology for the cultural evolution of early Homo sapiens. Here, we present the first evidence of a technique used for tar making in the Middle Stone Age. We created an experimental reference collection containing naturally available adhesives along manufactured tars from plants available in the Middle Stone Age and compared these to artifacts using gas chromatography-mass spectrometry and infrared spectroscopy. We found that, in the Howiesons Poort at Sibhudu Cave, tar was made by condensation, an efficient above-ground process. Even more surprisingly, the condensation method was not restricted to Podocarpus. The inhabitants of Sibhudu also produced tar from the leaves of other plants. These tars were then used, either without further transformation or were processed into ochre-based compound adhesives, suggesting that people needed different moldable substances with distinct mechanical properties. This has important implications for our understanding of Middle Stone Age H. sapiens, portraying them as skilled engineers who used and transformed their resources in a knowledgeable way.

Analyzing blank cutting edge efficiency associated with the adoption of microblade technology: A case study from Tolbor-17, Mongolia.

The phenomenon of lithic miniaturization during the Late Pleistocene at times coincided with increased artifact standardization and cutting edge efficiency-likely reflecting the use of small, sharp artifacts as interchangeable inserts for composite cutting tools and hunting weapons. During Marine Isotope Stage 2, Upper Paleolithic toolmakers in northern East Asia specifically used pressure techniques to make small, highly standardized lithic artifacts called microblades. However, little is currently known about how microblades affected the cutting edge efficiency of the toolkits they were a part of. We applied three methods of analyzing cutting edge efficiency to two Upper Paleolithic assemblages recently excavated from Tolbor-17, Mongolia, that document the periods before and after the introduction of microblade technology to the Tolbor Valley. A model incorporating allometric relationships between blank cutting edge length and mass suggests no difference in efficiency between the two periods, while two more conventional approaches both indicate a significant increase. The potential for improved cutting edge efficiency is only observed when the microblade sample is artificially inflated via simulation. Our results highlight challenges related to detecting and interpreting archaeological differences in cutting edge efficiency at the assemblage level.

Quantitative evaluation of science and technology financial policies based on the PMC-AE index model: A case study of China's science and technology financial policies since the 13th five-year plan.

The formulation of science and technology financial policies directly influences the direction of national economic development. Quantitative evaluation of these policies is an important method to reflect the consistency and strengths and weaknesses of policy interrelations. This paper analyzes 16 science and technology financial policy documents issued by the Chinese central government from 2016 to 2022, using text analysis and content analysis to extract keyword frequencies, and constructs 9 primary variables and 34 secondary variables. For the first time, a PMC-AE index model for science and technology financial policies is established, and a quantitative evaluation is conducted on 5 significant policy documents out of the 16. The results show that, from an overall analysis, Policy 1 and Policy 4 are at a good level, while the other three policies are at an excellent level. From the analysis of individual policy PMC-AE indexes, the rankings in descending order are: P2 > P5 > P3 > P4 > P1. Overall, the policies effectively meet the needs of China's science and technology financial development, with P2, P3, and P5 being at an excellent level, P4 at a good level, and P1 at an acceptable level, mainly reflecting the need for improvement in aspects such as policy synchronization with the current stage, targeted entities, guiding fields, and policy content. It is recommended that Chinese government departments should focus on five aspects in policy formulation: building a talent system for science and technology finance, improving the quality of financial services, coordinating central and local financial policies, protecting intellectual property rights in science and technology finance, and strengthening financial supervision. This will be conducive to the effective implementation of science and technology financial policies.

Factors affecting behavioral intentions of farmers in Southeast Asia to technology adoption: A systematic review analysis.

Agriculture remains one of the most vital economic sectors in Southeast Asia. However, the progress of this sector has been hindered by small-scale production, limited technology application, decreasing agricultural land size and quality, climate change, rapid urbanization, low productivity, and aging farmers. Technology adoption by rural farmers is still lacking, and the factors affecting farmers' behavioral intentions are still unclear, especially in Southeast Asia. Therefore, this study aims to determine the factors affecting behavioral intentions toward technology adoption among rural Southeast Asian farmers. A systematic literature review was performed to determine the factors affecting behavioral attention to technology adoption among smallholder farmers in Southeast Asia. Approximately 18 related studies were found based on the systematic review. According to the results of the study, farmers' behavioral intentions toward technology adoption can be classified as internal factors or external factors. Internal factors explain behavior, while external factors explain household, institutional, technological, social, and economic factors. The review revealed 21 factors categorized into five subthemes: household-specific factors, institutional factors, economic factors, technology factors, and behavior factors. This study is important because agriculture remains one of the most vital and pillar economic sectors in Southeast Asia. In addition, it has become a guideline for determining farmers' behavioral intentions toward the adoption of new agricultural technology.

Disruptive Technologies and Open Science: How Open Should Open Science Be? A 'Third Bioethics' Ethical Framework.

This paper investigates the ethical implications of applying open science (OS) practices on disruptive technologies, such as generative AIs. Disruptive technologies, characterized by their scalability and paradigm-shifting nature, have the potential to generate significant global impact, and carry a risk of dual use. The tension arises between the moral duty of OS to promote societal benefit by democratizing knowledge and the risks associated with open dissemination of disruptive technologies. Van Rennselaer Potter's 'third bioethics' serves as the founding horizon for an ethical framework to govern these tensions. Through theoretical analysis and concrete examples, this paper explores how OS can contribute to a better future or pose threats. Finally, we provide an ethical framework for the intersection between OS and disruptive technologies that tries to go beyond the simple 'as open as possible' tenet, considering openness as an instrumental value for the pursuit of other ethical values rather than as a principle with prima facie moral significance.

Life-Suspending Technologies, Cryonics, and Catastrophic Risks.

I defend the claim that life-suspending technologies can constitute a catastrophic and existential security factor for risks structurally similar to those related to climate change. The gist of the argument is that, under certain conditions, life-suspending technologies such as cryonics can provide self-interested actors with incentives to efficiently tackle such risks-in particular, they provide reasons to overcome certain manifestations of generational egoism, a risk factor of several catastrophic and existential risks. Provided we have reasons to decrease catastrophic and existential risks such as climate change, we also have a (defeasible) reason for investing in developing and making life-suspending technologies (more) widespread.

Calculation and analysis of the efficiency of resource allocation for technological innovation in China.

The efficiency of resource allocation in technological innovation is a critical factor influencing the output level of technological innovation. By expanding and optimizing the Hsieh & Klenow (2009) framework for analyzing the efficiency of resource allocation and relaxing the assumption of constant returns to scale, this study utilizes sample data from Chinese listed companies from 2007 to 2019 to measure and analyze the resource allocation efficiency level in China's technological innovation. The findings indicate that in the process of technological innovation, companies face heterogeneous resource usage costs, leading to a deviation from the optimal resource allocation state, with evident issues of resource misallocation. The loss of efficiency in technological innovation output due to resource misallocation is significant, and addressing this issue can substantially enhance the level of technological innovation output. The misallocation of research and development capital resources is more severe than that of research and development personnel, resulting in greater efficiency losses in technological innovation output. Government subsidies are identified as a significant factor affecting resource allocation in technological innovation. Addressing the issue of resource misallocation, accelerating the market-oriented reforms of technological innovation resource allocation, and optimizing the government subsidy screening mechanism are crucial for improving the efficiency of resource allocation in technological innovation.

Research on the enhancement path of green technology innovation efficiency under the group perspective.

China is at a critical moment of transforming high-speed development to high-quality development, and it is significant to improve the efficiency of green technological innovation. In this paper, under the perspective of two-stage innovation value chain, we construct the evaluation index system of green technology innovation efficiency, adopt the super efficiency SBM model to measure the green technology innovation efficiency of China's high-tech industries, and based on the results obtained, we assume the fuzzy set qualitative comparative analysis method (fs-QCA) based on the group theory to explore the complex causal mechanism and grouping paths of the interaction between enterprises, government and market that affects the green technology innovation efficiency Mechanism and group path. The study results show that (1) enterprise, government, and market are not necessary conditions to influence the efficiency of green technological innovation, and even if a particular party plays a central role, it needs the assistance of other parties. (2) The improvement of green technological innovation efficiency requires the interaction of enterprises, government, and market, and even if any party does not have the core conditions, it can still produce high green technological innovation efficiency. (3) The path of the "innovative compensation" effect is identified, which indicates that enterprises will generate a high level of green innovation efficiency under sufficient investment brought about by the enterprise scale effect and matched with a good level of economic development. (4) The market economy-led pathway suggests that when the market economy is highly developed, firms do not need environmental regulation and government support to generate efficient levels of green technological innovation.

Burnout and Attention Failure in STEM: The Role of Self-Control and the Buffer of Mindfulness.

Drawing on self-regulatory strength models of self-control, this research examined the relationship between burnout and attentional processes for STEM (science, technology, engineering, and mathematics) students. Using data from participants in STEM, burnout was found to be associated with higher levels of off-task thinking, also known as mind-wandering. Further, self-control acted as a mediator in the relationship between burnout and mind-wandering such that higher levels of burnout predicted poor self-control that subsequently increased the mind's tendency to wander. Additionally, mindfulness buffered the relationship between burnout and mind-wandering such that burnout had the most detrimental impact on attention for those students who were low in mindfulness. Using the Johnson-Neyman approach, results reveal the upper limits for the moderating impact of mindfulness. Results and implications for science and practice are discussed with a special grounding for students in the STEM context.

Revisiting the philosophy of technology and nursing: Time to move beyond romancing resistance or resisting romance.

Technology remains enmeshed in our daily lives and given its continuing presence in clinical practice and rapid technological proliferation; it becomes relevant for nurses to examine techno-onto-epistemology in relation to the discipline of nursing. This is critical considering the intersection of technology and nursing remains an area of ongoing discussion revealing a need for further philosophical reflection. To this end, this paper sought to examine the philosophy of technology from the engineering and humanities perspectives to contribute to the discussion regarding its intersection with the onto-epistemology of nursing. Although technology seems to be constantly present in nursing practice, two opposing perspectives reflecting a love-hate relationship is highlighted: technological optimism (promotes technology) and technological romanticism (dissuades technology). Based on Mitcham's interpretation of 'mutual relationship' and 'being-with', a potential way to break away from the binary perspectives is to view the intersection of/relationship between technology and nursing as being on a continuum rather than entirely monolithic entities. Caring is presented as multidimensional reflecting actions and attitudes. Arguably, some caring actions may intersect with the engineering perspective to suggest that technology can support nurses in their roles, that is, by imitating some of what nurses do, but not to replace them. From the humanities perspective, technology is presented as a way of being with humans exercising control over what technology has to offer. Put together, it is clearly time to break away from the love-hate relationship between nursing and technology. Although this emphasises a great need to build the technological competency of nurses, there is an even greater call for nurses to reflect on and voice the epistemological, ontological, axiological, and ethical issues that the application of technology raises for the discipline.

The Making of Future Scientists: Faculty Mentor Cultural Awareness and Inclusive Science Labs.

A compelling body of research suggests that students from racially marginalized and minoritized (RMM) backgrounds are systematically deterred from Science, Technology, Engineering, and Math (STEM) fields when teachers and scientists create ideologically colorblind STEM learning environments where cultural differences are deemed irrelevant and disregard how race/ethnicity shapes students' experiences. We examine whether and how STEM faculty can serve as important sources of information that signal racial/ethnic diversity inclusion (or exclusion) that influence RMM students' motivation to persist in STEM. Specifically, we focus on RMM students' perceptions of their faculty research mentors' cultural awareness-the extent to which students believe that their faculty research mentor acknowledges and appreciates racial/ethnic differences in STEM research. Results from a longitudinal survey of RMM students (N = 150) participating in 74 faculty-led STEM research labs demonstrated that RMM students who perceived their faculty research mentor to be more culturally aware experienced more positive social climates in the lab and were more identified as scientists. Increased science identity, in turn, predicted their motivation to pursue STEM careers 3 months later. These findings demonstrate the importance of acknowledging, welcoming, and celebrating racial/ethnic diversity within STEM learning environments to broaden inclusive and equitable participation in STEM.

An Exploratory Mixed-Methods Analysis of Factors Contributing to Students' Perceptions of Inclusion in Introductory STEM Courses.

In this exploratory mixed-methods analysis of students' perceptions of inclusion in introductory STEM courses for STEM majors, we asked students to rate inclusion in their class and to provide an open-text explanation of their rating. Analyzing 1930 qualitative responses resulted in a codebook containing academic, identity, and nonspecific categories. The majority of responses (>80%) cited academic factors such as interactions between students and instructors or course elements and policies. Most academic responses aligned with evidence-based teaching practices fostering inclusion, describing a range of strategies and policies instructors can implement to increase students' perceptions of inclusion. A small number of student responses indicated that their perception of the required knowledge background for the course impacted course inclusivity. Few differences in frequency distributions were found between subgroups examined (gender, race and ethnicity, self-reported inclusion score, and discipline). Additionally, tracking a subset of students (135) across three courses revealed that most (80%) cited different factors influencing their perception of inclusion in each course. This suggests students' perceptions of inclusive practices are complex, and most students recognize multiple factors that influence their inclusion. Overall, our findings suggest instructors can significantly influence students' perceptions of inclusion by using multiple inclusive teaching strategies and course policies.

Emotion regulation skills as a mediator of STEM teachers' stress, well-being, and burnout.

The teaching profession highly stressful, and teachers are often faced with challenging situations. This is particularly the case in STEM (science, technology, engineering, and math) education, which is a uniquely demanding and challenging field. This study examined the role of emotional regulation (ER) skills in STEM teachers' stress, well-being, and burnout. The sample included 165 STEM teachers in middle and high schools who completed standard online questionnaires on ER, stress, well-being, and burnout. They were also asked to comment on three videos depicting authentic mathematical and pedagogical situations. The results indicated that contrary to popular belief, seniority was not linked with levels of stress, difficulties in ER, lower levels of well-being, or higher levels of burnout. A structural equation model and bootstrapping analysis showed teachers' levels of stress predicted their well-being, and this link between stress and well-being was mediated by teachers' level of difficulty in ER. The study highlights the importance of STEM teachers' well-being and suggests the need to reduce stress and burnout by providing tools for teachers to regulate their emotions in the classroom.
