Amina Al-Saʿid: a liberal femocrat under state feminism

ABSTRACT This article discusses the public life of the Egyptian journalist and feminist Amina al-Saʿid (1914–1995), who has hardly received any scholarly attention. On the one hand, it examines her shortcomings as a feminist, and on the other hand, it investigates the contribution of her journalistic work to Egyptian feminism in the decades following the 1952 revolution. During this period, under an authoritarian and centralist regime that promoted state feminism but closed women’s organizations, women such as al-Saʿid allegedly turned into femocrats who preferred their government-supported positions over solidarity with women of other classes and ideological beliefs. By examining the femocrat as an analytical category, this article undermines the perspective of femocrats in authoritarian centralist rule as lacking any agency—particularly feminist agency—and argues instead that al-Saʿid’s lack of explicit political solidarity with feminist activists whom the government silenced were a fruit of her liberal pre-revolutionary upbringing rather than merely being a byproduct of her alliance with the Nasser regime. Importantly, it argues that she continued to make a significant contribution to maintaining a feminist political presence and mediating the implications of state reforms for the reconstruction of gender identity and relations.

Students’ prompt patterns and its effects in AI-assisted academic writing: Focusing on students’ level of AI literacy

The increase of generative artificial intelligence (GenAI) in education has emphasized prompt literacy and design, influencing the experience of GenAI-assisted learning. However, there is limited understanding regarding the various prompt patterns that emerge during student-GenAI interaction (SAI) within the context of navigating learning tasks at different levels of AI Literacy or how these patterns are associated with task performance. This study analyzed 19 university students’ prompt patterns when interacting with GenAI on academic writing tasks, grouping students by AI literacy level and examining how prompt patterns relate to performance. This study performed content analysis of student-GenAI chat histories and categorical data analysis of student interviews. Pattern differences were then visualized using Gephi 0.10.1. Distinctive prompt patterns were identified: high AI literacy students exhibited descriptive, context-based prompts in collaborative interactions, while low AI literacy students demonstrated general prompts in a student-directed approach. Additionally, student essays were evaluated by five experts to inform how prompt patterns relate to task performance and the Wilcoxon signed-rank test was applied. The two groups demonstrated significant differences across categories of writing performance (content, structure, and expression). This study provides implications for designing and implementing GenAI and student-centered AI-assisted instruction.

Sex-Dependent Variations in Gene Expression in Corneal Endothelial Cells Among Healthy Individuals and Patients With Fuchs Endothelial Corneal Dystrophy.

Fuchs endothelial corneal dystrophy (FECD) displays a higher incidence in females than in males, yet the underlying mechanism remains unclear. This study aimed to elucidate sex-dependent differential gene expressions in corneal endothelial cells (CECs) from healthy non-FECD individuals and from patients with FECD. RNA-Seq data from CECs of non-FECD subjects (3 males, 4 females) and FECD subjects (5 males, 5 females) were analyzed to identify differentially expressed genes (DEGs) between the sexes. We used heatmaps and principal component analysis for expression pattern visualization and Gene Ontology analysis for functional categorization of DEGs. Among the non-FECD subjects, we identified 341 DEGs-143 upregulated and 198 downregulated-in females relative to males. For FECD subjects, 309 DEGs were discovered, with 215 upregulated and 94 downregulated in females compared with males. Heatmaps exhibited hierarchical clustering by sex, whereas principal component analysis delineated distinct male and female clusters in both non-FECD and FECD cohorts. Gene Ontology enrichment analysis linked the upregulated genes in non-FECD females to steroid hormone response, and downregulated ones to cyclin-dependent protein kinase activity. In females with FECD, upregulated genes were associated with immune responses and downregulated genes with peptide hormone binding. To our knowledge, these findings are the first to reveal distinct gene expression patterns in CECs between sexes. The observed variations suggest a potential genetic basis for the observed sex disparity in FECD prevalence. Further investigation is warranted to explore these associations and their implications for the pathogenesis of FECD.

Endoscopic surgery affects the gut microbiota and its metabolism in breast cancer patients.

Despite the advantages of endoscopic surgery in reducing trauma and enhancing recovery for breast cancer patients, its impact on gut microbiota, which is crucial for health and estrogen metabolism, remains unclear. Further investigation is necessary to fully understand this impact and its implications. Between June and December 2022, fecal samples were collected from 20 patients who underwent endoscopic surgery. The gut microbiota composition was determined using 16S rRNA sequencing, while the metabolites were analyzed through liquid chromatography-tandem mass spectrometry (LC-MS/MS). Bioinformatics and statistical analyses were employed to identify significant alterations in microbial taxa abundance and to assess intergroup differences. These analyses included t-tests for pairwise comparisons, one-way ANOVA for multiple group comparisons, and chi-square tests for categorical data analysis. Endoscopic surgery in breast cancer patients subtly changed gut microbiota diversity and composition. Post-surgery, there was a reduction in Lachnospiraceae, Monoglobaceae and Firmicutes to Bacteroides ratios. Shifts in metabolites were also observed, the changed metabolites impacted pathways such as primary bile biosynthesis and Ascorbate and aldarate metabolism, with PE(PGD1/18:1(9Z)) identified as a key differential metabolite that increased post-surgery. Azasetron, tyramine glucuronide, DL-DOPA, phthalide, acetophenazine, aciclovir, creatinine bicarbonate, and 4-oxo-L-proline being associated with distinct bacterial taxa. Breast cancer patients undergoing endoscopic surgery experience a shift in their gut microbiota and metabolic profiles. Therefore, postoperative management, with a particular focus on the adjustment of the gut microbiota, is crucial for enhancing patient recovery and health outcomes.

Observational studies on per- and polyfluoroalkyl substancetoxicity in marine species: hints for the extrapolation of a screening value.

A statistical procedure has been developed to derive a screening value from an observational study related to the developmental toxicity observed in loggerhead turtle (Caretta caretta) eggs exposed to long chain per- and polyfluoroalkyl substances (PFAS). A dataset of 41 nests in which the hatching rate was inversely correlated with the increase in the PFAS concentration in unhatched eggs was processed via a categorical regression approach. After outliers identification and removal, categorical regression analysis tested the relationships of the outcomes with the following parameters: perfluoro-nonanoic (PFNA), decanoic (PFDA), undecanoic (PFUdA), and dodecanoic (PFDoA) acids; perfluoroctansulfonate (PFOS); polychlorobiphenyls (PCBs) 28, 52, 101, 138, 153, 180; lead (Pb), total mercury (Hgtot), and cadmium (Cd); and other factors, such as "nest site," "clutch size," "incubation duration," and "nest minimum depth," as confounders/modifiers of the hatching rate. Among considered contaminants, PFOS, PFDA, and PFNA only were significant (p ˂ 0.05), as were "nest site," "clutch size," and "incubation duration," confirming their possible role in decreasing the hatching rate of sea turtle eggs. According to a chemical-specific visual strategy, PFOS only showed a typical monotonic dose/response curve, which allowed the identification of provisional hypothetical thresholds of PFOS, 1,386 (CI95 = 1,080-1,692) ng/kg, corresponding to average hatching rates of 93.3% (CI95 = 91.4%-95.2%). Our preliminary results indicate the feasibility of the extrapolation of a screening value from observational studies under the following requirements: (a) individuation of most influencing factors for the outcome; (b) datasets referred to baseline contamination; (c) selection of undisturbed nests; (d) appropriate statistical multivariate methodology. This work aims to contribute to the New Approach Methods (NAMs) to assess PFAS early-stage embriotoxicity in marine biota.

Sex, Gender, and Bodies: Transmisogyny and Garfinkel's Status Degradation Ceremony

Hatred and fear of trans people, particularly trans women, are worldwide social phenomena. Transphobic rhetoric rests on essentialist understandings of sex and gender, but ethnomethodology shows how the “natural attitude” to sex/gender is a practical accomplishment. We use conversation analysis and membership categorization analysis to examine the workings of the natural attitude in a public submission to a government select committee about a law that would affect transgender people. We adapt Garfinkel's concept of the status degradation ceremony to show how the submission systematically used categories of sex and gender to present trans women as illegitimate and dangerous in women's spaces. We also show how the submission was recognized as transmisogynistic and challenged by government ministers of the select committee. We thus show how people can accomplish and challenge transmisogyny through common‐sense knowledge about sex and gender.

Lived Religion and Shared Experience in Late Medieval and Early Modern Europe

This special issue of JMEMS takes up the classical debate on the “shared” and the “individual” through the concepts of “lived religion” on the one hand and “experience” on the other. The collection presents the state-of-the-art within the emerging field of history of “lived religion,” exemplifying its differences from earlier notions of “popular religion.” The articles take a step forward in the field of lived religion by approaching it from the perspective of experience as an analytical category. The issue considers experience as it occurs in three fundamental stages: (1) ways in which individual people and communities encounter the world; (2) the simultaneous relational, intersubjective process making sense of those encounters; and (3) the social and physical structures born from the repetition of these processes so as to produce knowledge of the “real” world. Approaching the topic in terms of these stages of experience allows the articles to investigate negotiations between individual and communal or shared experience in the field of lived religion within various geographical contexts of medieval and early modern Europe. Such an approach helps to better identify the drivers of historical change across medieval and early modern periods.

Enhancing anthropometric proficiency: Effect of a structured training program on skills of Anganwadi workers in rural areas of Raebareli District, Uttar Pradesh

ABSTRACT Context: Anganwadi workers (AWWs) require technical skills for growth monitoring of under-five children. Anthropometric skills help Anganwadi workers assess any changes or deterioration in the normal growth of children. Aims: To determine the effect of a structured training program on the anthropometric skills of Anganwadi workers in rural areas of Raebareli district in Uttar Pradesh. Settings and Design: A community-based interventional study, was conducted among 162 AWWs, 73 from Salon and 89 from Rahi development blocks of Raebareli district. Methods and Material: The skills of AWWs in anthropometric measurement domains (weight, height/length, and mid-upper arm circumference) were assessed using a pre-tested observatory checklist both before and after the training sessions. The skills for each domain were assessed on four points i.e. standard procedure applied to the child, assurance of safety precautions, observer protocol during anthropometry, and precision and accuracy in recording measurement. Statistical Analysis Used: The McNemar Chi-square test was used for paired categorical data analysis. P < 0.05 was considered to be statistically significant. Results: The mean age of the study population was 43.30 ± 9.68 years. The mean years of their job was 16.68 + 7.38 years. About one-fourth (26.5%) of AWWs had received training within the last three years. Inadequate/non-functional equipment (9.8%), low honorarium (29.4%), interruption in timely supply of supplementary food (6.3%), non-cooperation of the community (84.6%), insufficient space (58.0%), and availability of periodic job aids (16.8%) were the major challenges that were faced by ICDS workers. The anthropometric skills of the AWWs were found to improve significantly in almost all the domains. The proportion of AWWs following standard procedure, assurance of safety precautions, observer protocol during anthropometry, precision, and accuracy on recording measurement were found to increase significantly after a structured training program. (P < 0.05). Conclusions: A structured training programme focusing anthropometric skills on play an important role in increasing the skills of AWWs in growth monitoring. AWWs’ capacity to monitor child growth must be refreshed regularly through separate focussed training programs rather than during comprehensive sessions.

Identity categories and the dilemma of calling police about family violence.

The under-reporting of family violence is a global problem. Multiple barriers to help-seeking have been identified, including some associated with social identities like race, age and gender. This discursive psychology study examines identity and help-seeking in social interaction. We analysed 200 calls classified by police call-takers as family harm using conversation analysis and membership categorization analysis. We found that callers oriented to a locally generated identity category 'the one who called police' as problematic. Callers sought anonymity or proposed cover stories to avoid being identified by others. Anonymity raised practical problems for recording callers' names and cover stories raised questions about the legitimacy of alternative accounts for police contact. We found callers' concerns with being identified create a dilemma produced through competing moral judgements tied to coexisting institutional and relational identity categories. Participants display understandings that calling the police may be the right thing to do as a help-seeker, but the wrong thing to do as a friend or family member. Our findings reveal how a locally generated identity category was observable as a force shaping help-seeking in real-time high-stakes encounters.

Development of new standardized methods for calculating fuel poverty index: a study in the coast of Cabo Corrientes Jalisco

Fuel poverty poses a significant challenge to communities worldwide, particularly in vulnerable regions. Within this context, energy poverty is understood as the inability of households to access basic energy services, representing a barrier to sustainable development and social welfare. This article addresses the need for the development of standardized methodologies for measuring and analyzing energy poverty. In response to the absence of unified approaches for comparative analysis of energy poverty across different geographical contexts, this paper proposes a new methodology, based on data collected from coastal localities in the State of Jalisco. A principal component analysis was conducted, generating a normalized multivariate matrix, and through clustering analysis, similar criteria were grouped into different analytical categories. By applying this method, an adaptation of the Gini Index and Lorenz curves was achieved to precisely calculate an Energy Poverty Index, specifically in the coastal region of Cabo Corrientes, Jalisco.

Alcune note sociologiche (ma non solo) sulla mentalità dei genovesi

Mentality, an ambivalent analytical category, is in fact a relevant resource from a cultural point of view due to its reflections on the concrete behaviors of both the individual and a community. The essay attempts to reflect sociologically on the mentality with reference to a specific case study: the Genoese people. Here focus only on three interdependent aspects, that traditionally contribute to the configuration of the Genoese mentality: avarice, grumbling and the fear of the new expressed in the lexicon of the maniman. Some banal stereotypes are thus dismantled. This preliminary exploration adopts an interdisciplinary methodology based on a plurality of sources and data in the hope of further insights.

Migration and Diverse Belongings in a Neighbourhood Context: Population‐Based Study of Older Russian‐Speaking Migrants in Finland

ABSTRACTBelonging is a fundamental human experience that plays a critical role in shaping individuals' connections to their communities. Establishing a sense of belonging to a destination society can be particularly challenging for older migrants. Neighbourhood factors and the broader regional context may influence one's sense of belonging to various communities. However, research exploring how neighbourhood‐level factors relate to different types of belonging remains limited. Using data from a population‐based study on older Russian‐speaking migrants in Finland (n = 1082, 57% men and 43% women; mean age 63.2 years, 36% response rate) and a postal code area database (3036 postal codes on mainland Finland, with an average of 1802 residents and an average area of 112 km2), we examined various types of belonging among Russian‐speaking migrants aged 50 years or older and how both individual and neighbourhood‐level factors were associated with the types of belonging. Categorical Principal Component Analysis (CATPCA) was employed to study types of belonging, and multilevel regression analysis was used to examine associations between the types and neighbourhood and individual factors that were identified. Three types of belonging were identified: belonging to the majority population, that is, ‘Finns’; belonging to Ingrian Finns; and belonging to Russian speakers. In neighbourhoods with a higher proportion of Russian speakers, belonging to Finns was weaker. Moreover, significant differences in belonging to Russian speakers were observed across regions of Finland. Thus, in regions located near the Finnish–Russian border, belonging to Russian speakers was stronger. Although neighbourhood characteristics were not associated with belonging to Ingrian Finns, individual‐level factors, such as being older, receiving income support, and having lower education levels were associated with this type of belonging. Additionally, good command of the local language contributed to belonging to Finns and weakened belonging to Russian speakers.

Identifying metaphors towards physiotherapists.

The aim of this study was to identify mental images that physiotherapists and student physiotherapists have regarding the concept of physiotherapist through metaphors. The study was a mixed-methods research that combined latent content analysis and categorical data analysis. Data were collected from 207 physiotherapists or physiotherapy students. Content analysis, a qualitative method, was performed on the raw data, which was composed of each participant's statement completing the following sentence "Physiotherapist is like… because…". Metaphors for physiotherapists were centered around 12 concepts. Most cited metaphor by student physiotherapists was "healer" (29.4%) and it was "guiding" (17.2%) for in-service physiotherapists. The rate of the "negative connotation" category in in-service physiotherapists (7.1%) was 2% higher than that of the student physiotherapists. Women mostly emphasized the "healer" (21.9%) category, while men mostly emphasized the "healer" and "supporter" (17.8%) categories. Participants aged under 25 and 26-35 age group were mostly in the "healer" category (26.4% and 18.8%, respectively) but the participants aged 36 years and over mostly opted for "guiding" and "supporter" (20.0%). There were fundamental differences between student physiotherapists and in-service physiotherapists in terms viewpoint regarding physiotherapy as a profession, and that these differences vary by gender and especially by age. During the undergraduate period, it will be beneficial to ensure that students have a realistic perspective with versatile training programs.

Needs, rights and perspectives in the Birth Care Pathway during COVID-19 lockdown in Italy: the BiSogni Study, an exploratory qualitative research

BackgroundWith the COVID-19 emergency, the provision of healthcare had to be reorganized. Community Health Services for Families of Trieste adopted new methods to ensure continuity of care and the maintenance of the Standards and Good Practices of the Baby Friendly Initiative of UNICEF for the Birth Care Pathway.The aim of the study was to identify the perceived needs of women, couples, caregivers, and health professionals during the COVID-19 pandemic and evaluate new healthcare strategies, identifying weaknesses and strengths, and future developments.MethodsThis was an exploratory qualitative study, using online Focus Groups (FGs) with mothers, fathers, pregnant couples, grandparents, peer breastfeeding support mothers’ groups, and healthcare professionals (HCPs). The sample was purposeful, selected through the district healthcare network. After obtaining participants’ consent, FGs were recorded and fully transcribed. Transcripts underwent deductive and inductive categorical analysis using Nvivo12 software.ResultsTen FGs were conducted with 86 participants. Situations of increased vulnerability were reported by women who experienced significant levels of loneliness during pregnancy, childbirth, and the first months of their child's life. Regarding healthcare pathways, inconsistencies in the information provided by healthcare services emerged, due to the lack of clear national guidelines for managing childbirth during the pandemic. A controversial healthcare practice was the widespread exclusion of partners from antenatal care, prenatal diagnostics, labour, delivery, and postnatal care. After a period of uncertainty and fear experienced by families and HCPs, significant improvements in the organisation of community and hospital services were described. This was aided by telemedicine, which re-established a sense of care and connection.Positive aspects of the lockdown included a major presence of fathers who could work from home, share daily life with their partners, and take care of their children.ConclusionsThe COVID-19 emergency has reshaped the provision of healthcare, even in the field of childbirth. Innovative methods have proven to effectively address new needs resulting from physical and social distancing. These strategies could promote sustainable organisational approaches for managing childbirth care. Our results highlighted how policies and practices for future healthcare emergencies could ensure adherence to best practices and promote patient’s rights.

A munkaidő-szervezés alapvető forrásai történeti perspektívából

The concepts of status and contract are well-established and frequently used analytical categories of good explanatory power in classical and contemporary international labour law literature. Since the interpretation of these concepts varies from era to era and from author to author, recent Hungarian legal literature has paid little attention to the interpretation of legal developments along this theoretical framework, although it could serve as an effective reference point for grasping the trends of existing law. This paper attempts to apply these concepts to describe the regulatory trends in a volatile and conflictual area of law, namely working time.

Effects of vagus nerve stimulation on daily function and quality of life in markedly treatment-resistant major depression: Findings from a one-year, randomized, sham-controlled trial.

Depression treatments aim to minimize symptom burden and optimize quality of life (QoL) and psychosocial function. Compare the effects of adjunctive versus sham vagus nerve stimulation (VNS) on QoL and function in markedly treatment-resistant depression (TRD). In this multicenter, double-blind, sham-controlled trial, 493 adults with TRD and ≥4 adequate but unsuccessful antidepressant treatment trials (current episode) were randomized to active (n=249) or sham (n=244) VNS (plus treatment as usual) over a 12-month observation period. Quarterly outcomes included QoL with the Q-LES-Q, Mini-Q-LES-Q, and EQ-5D-5L, and function with the WHODAS 2.0 and Work Productivity and Activity Impairment Questionnaire (WPAI) item 6. Differences between treatment groups in change in scores from baseline and percentage of time with a meaningful response in Q-LES-Q, Mini-Q-LES-Q, and WPAI item 6 scores were analyzed. Active VNS was superior to sham in mean change in scores from baseline in the Mini-Q-LES-Q (P=0.050) and WPAI item 6 (health condition's effect on regular activities [P=0.050]) used as continuous variables, with a similar trend for Q-LES-Q (P=0.061). Active VNS was superior to sham in time spent in clinically meaningful benefit (categorical analyses) using the Q-LES-Q (P=0.029), Mini-Q-LES-Q (P=0.011), and WPAI item 6 (P=0.039). The WHODAS 2.0 (P=0.304) and EQ-5D visual analog scale (P=0.125) failed to reveal between-group differences. Active VNS was superior to sham VNS in improving QoL and psychosocial function in patients with TRD. VNS has a broader therapeutic impact than symptom improvement alone in patients with marked psychosocial impairment.

Stimulating Political Imagination With Arts-Based Methods: The Case of Utopia Consultation

In this article, we identify ways to methodologically stimulate political imagination in sociological research by exploring an art concept called ‘utopia consultation’ and related arts-based exercises. We investigate how political imagination can be stimulated and practised through arts-based research methods in sociology, and what tangible tools arts-based research offers for studying the intangible. Our analysis builds on recent work on utopia, understood as a tool rather than a blueprint, and sociology of the future, which focuses on the future as an analytical category. We draw on 18 one-on-one utopia consultation sessions conducted in 3 upper secondary schools in Finland, and 3 facilitated collective discussions with the participants in each education institution to discuss their experiences of the one-on-one utopia consultations. Based on our analysis, we suggest four key methodological practices for stimulating political imagination: dialogue, play, cultivating a hopeful orientation to the not-yet, and collective utopian negotiation. We advance sociological discussions of methodology around utopia and political imagination, and contribute to sociological work on the intangibility of discovering the not-yet through arts-based methods by identifying tangible practices and tools for studying the intangible.

Phylogenetic Diversity of Live‐Bearing Fishes (Poeciliidae) Peaks on Peninsulas, Isthmuses, and in Deserts

ABSTRACTAimPoeciliids are ecologically important, are widely used as pets, and also have value as model organisms. To understand diversity within this family, we study their phylogenetic diversity (PD) at regional and local scales to delimit bioregions and identify patterns of biodiversity.LocationThe Americas.TaxonPoeciliidae (Actinopterygii: Cyprinodontiformes).MethodsWe expanded an existing dated phylogeny from 164 to 261 species with distributional data for 1o × 1o latitude × longitude cells (~111 km2) and conducted a cluster analysis (phylo‐jaccard distance) to delineate bioregions. For individual cells, we mapped species richness (SR), phylogenetic diversity (PD), weighted endemism (WE) and phylogenetic endemism (PE). We used randomisation tests to map phylogenetic clustering and over‐representation of short‐branch species by cell. We used categorical analysis of neo‐ and palaeo‐endemism to map neo‐, palaeo‐, mixed and super (mixed) endemism.ResultsWe delineated six bioregions. Highest regional species density and density of PD occurred on the Isthmus of Panamá (IOP). At the grid‐cell scale, the Grijalva–Usumacinta drainage is a hotspot for SR, PD, PE and WE; the IOP has high PD and PE; the Isthmus of Tehuantepec (IOT) has high PD, WE and moderately high SR; and western Hispaniola has high WE and moderately high SR. The Grijalva–Usumacinta drainage also includes cells of super (mixed) and palaeoendemism, while mixed endemism is widespread in Middle America and the Greater Antilles. Phylogenetic clustering is widespread, whereas over‐representation of short‐branch species is concentrated in the Chihuahuan Desert–Sierra Madre Oriental region and in western Hispaniola, both hotspots of neoendemism.Main ConclusionsWe found widespread diversification of genera intermixed with relict species (mixed endemism). Furthermore, SR and PD were strongly correlated. Centres of endemism include the Chihuahuan Desert–Sierra Madre Oriental, western Hispaniola, the IOT, the IOP and (most of all) the Grijalva–Usumacinta drainage. However, conservation efforts must occur within each bioregion and for each genus.

(Re)productivity: a category for the critical analysis of bioeconomic approaches

Serving as a mediating category and calling for sustainable development toward a reinvention of what is understood to be “economic,” the category of (re)productivity overcomes the divisive structure of modern capitalist economies. (Re)productivity can be understood as a socio-ecological category that builds on feminist economic criticism and critical approaches to ecological economics. The thesis of this article is that only with the help of the category of (re)productivity can bioeconomy truly be understood as a sustainable economic system: There can be no sustainable bioeconomy based on traditional economic approaches. (Re)productivity also recognizes “natural productivity” – that is, the living forces and creative abilities of nature as they are understood in terms of their economic significance at both the beginning and the end of the (re)production process. Indeed, nature always constitutes materialized social relations to nature. For a sustainable economy, this means that nature must be co-created in such a way that future generations retain options when it comes to their own economic activity and living a good life. In this article, we further systematize these ideas. To this end, the concept of bioeconomy as defined by the German government (as a frontrunner to the definition and propagation of the concept) is briefly outlined to then introduce the notion of (re)productivity as an analytical and shaping category. This is followed by a discussion of the concept of “nature” from the perspective of a sustainable (re)productive economy. The conclusion returns to the thesis and postulates precaution as a principle of economic action.
