The recent finding that the human version of a neurodevelopmental enhancer of the Wnt receptor Frizzled 8 (FZD8) gene alters neural progenitor cell cycle timing and brain size is a step forward to understanding human brain evolution. The human brain is distinctive in terms of its cognitive abilities as well as its susceptibility to neurological disease. Identifying which of the millions of genomic changes that occurred during human evolution led to these and other uniquely human traits is extremely challenging. Recent (...) studies have demonstrated that many of the fastest evolving regions of the human genome function as gene regulatory enhancers during embryonic development and that the human‐specific mutations in them might alter expression patterns. However, elucidating molecular and cellular effects of sequence or expression pattern changes is a major obstacle to discovering the genetic bases of the evolution of our species. There is much work to do before human‐specific genetic and genomic changes are linked to complex human traits. (shrink)

In the book The Insect Societies, Wilson proposed categories of sociality that were presented as a landmark unification of terminology in the study of social behavior. Since then, many new behavioral patterns have been described, but they could not be fitted into any of the available categories, undermining the consensus around that well-established classification. New general classifications tried to circumvent the limitations shown by Wilson’s categorization, but with little success. Among the proposals, some maintain the form of discrete categorization, while (...) others advance a quantitative model to characterize sociality. These proposals have failed to clarify the use of the categories of sociality, and none of them has become widely accepted or overcome the problems faced by the classification of social behaviors. Here we explore whether an analysis of types of concepts proposed by Carnap can help to move forward in this discussion. His distinction between qualitative concepts and quantitative concepts is used here as an epistemological basis for analyzing the development of the proposed conceptual changes and classifications of sociality. Recently, social behavior has come to be considered a complex phenomenon, and quantitative concepts could bring a lot of informative data to understanding its development and perhaps its evolution. We conclude that a new metric of sociality should be built, using characteristics that are nonarbitrary, evolutionarily meaningful, and amenable to comparing all social animals. Finally, we advocate for an integrative view of social complexity based on individuals’ interactions as a useful metric of sociality. This approach still needs further development. (shrink)

Recently, psychological phenomena have been expanded to new domains, crisscrossing boundaries of organizational levels, with the emergence of areas such as social personality and ecosystem learning. In this contribution, we analyze the ascription of an individual-based concept (personality) to the social level. Although justified boundary crossings can boost new approaches and applications, the indiscriminate misuse of concepts refrains the growth of scientific areas. The concept of social personality is based mainly on the detection of repeated group differences across a population, (...) in a direct transposition of personality concepts from the individual to the social level. We show that this direct transposition is problematic for avowing the nonsensical ascription of personality even to simple electronic devices. To go beyond a metaphoric use of social personality, we apply the organizational approach to a review of social insect communication networks. Our conceptual analysis shows that socially self-organized systems, such as isolated ant trails and bee’s recruitment groups, are too simple to have social personality. The situation is more nuanced when measuring the collective choice between nest sites or foraging patches: some species show positive and negative feedbacks between two or more self-organized social structures so that these co-dependent structures are inter-related by second-order, social information systems, complying with a formal requirement for having social personality: the social closure of constraints. Other requirements include the decoupling between individual and social dynamics, and the self-regulation of collective decision processes. Social personality results to be sometimes a metaphorical transposition of a psychological concept to a social phenomenon. The application of this organizational approach to cases of learning ecosystems, or evolutionary learning, could help to ground theoretically the ascription of psychological properties to levels of analysis beyond the individual, up to meta-populations or ecological communities.

A revision of the author's thesis, Harvard University, 1967.

We performed three experiments to investigate whether adjectives can modulate the sensorimotor activation elicited by nouns. In Experiment 1, nouns of graspable objects were used as stimuli. Participants had to decide if each noun referred to a natural or artifact, by performing either a precision or a power reach‐to‐grasp movement. Response grasp could be compatible or incompatible with the grasp typically used to manipulate the objects to which the nouns referred. The results revealed faster reaction times (RTs) in compatible than (...) in incompatible trials. In Experiment 2, the nouns were combined with adjectives expressing either disadvantageous information about object graspability (e.g., sharp) or information about object color (e.g., reddish). No difference in RTs between compatible and incompatible conditions was found when disadvantageous adjectives were used. Conversely, a compatibility effect occurred when color adjectives were combined with nouns referring to natural objects. Finally, in Experiment 3 the nouns were combined with adjectives expressing tactile or shape proprieties of the objects (e.g., long or smooth). Results revealed faster RTs in compatible than in incompatible condition for both noun categories. Taken together, our findings suggest that adjectives can shape the sensorimotor activation elicited by nouns of graspable objects, highlighting that language simulation goes beyond the single‐word level.

Frictions between work and family life have increased during the COVID-19 pandemic, causing negative consequences on the mental health and quality of life of workers. Without validated instruments, it is not possible to determine the impact of Work-Family and Family-Work conflict. To date, no studies have been conducted to provide evidence of the validity and reliability of The Survey Work-Home Interaction Nijmegen in the population of Argentine workers. The SWING was administered to 611 Argentine workers of both sexes aged between (...) 18 and 70 years selected from a non-probabilistic accidental sampling. The confirmatory factor analysis showed satisfactory fit indices of the original four-factor model. The level of reliability was acceptable. The relationships of the subscale scores with the engagement and burnout variables were as expected according to previous studies. Having an instrument adequately adapted to the population of Argentine workers facilitates the development of studies aimed at evaluating the role of W-F or F-W interactions and their implications for health and productivity.

"Hegel’s Philosophical Psychology" draws attention to a largely overlooked piece of Hegel’s philosophy: his substantial and philosophically rich treatment of psychology at the end of the 'Philosophy of Subjective Spirit', which itself belongs to his main work, the "Encyclopaedia of the Philosophical Sciences". This volume makes the case that Hegel’s approach to philosophy of mind as developed within this text can make an important contribution to current discussions about mind and subjectivity, and can help clarify the notion of spirit within (...) Hegel’s larger philosophical project. Scholars from different schools of Hegelian thought provide a multifaceted overview of Hegel’s 'Psychology': Part I begins with an overview of Hegel’s 'Philosophy of Subjective Spirit', which outlines both its historical context and its systematic context within Hegel’s philosophy of subjective spirit. Parts II and III then investigate the individual chapters of the sections on psychology: the theoretical mind and the practical and free mind. The volume concludes by examining the challenges which Hegel’s 'Psychology' poses for contemporary epistemological debates and the philosophy of psychology. Throughout, the volume brings Hegel’s views into dialogue with 20th- and 21st-century thinkers such as Bergson, Bourdieu, Brandom, Chomsky, Davidson, Freud, McDowell, Sellars, Wittgenstein, and Wollheim.

Current treatments for chronic pain have limited benefit. We describe a resilience intervention for individuals with chronic pain which is based on a model of viewing chronic pain as dysregulated homeostasis and which seeks to restore homeostatic self-regulation using strategies exemplified by survivors of extreme environments. The intervention is expected to have broad effects on well-being and positive emotional health, to improve cognitive functions, and to reduce pain symptoms thus helping to transform the suffering of pain into self-growth. A total (...) of 88 Veterans completed the pre-assessment and were randomly assigned to either the treatment intervention or control. Fifty-eight Veterans completed pre- and post-testing. The intervention covered resilience strengths organized into four modules: engagement, social relatedness, transformation of pain and building a good life. A broad set of standardized, well validated measures were used to assess three domains of functioning: health and well-being, symptoms, and cognitive functions. Two-way Analysis of Variance was used to detect group and time differences. Broadly, results indicated significant intervention and time effects across multiple domains: Pain decreased in present severity [F = 5.02, p < 0.05, η2p = 0.08], total pain over six domains [F = 14.52, p < 0.01, η2p = 0.21], and pain interference [F = 6.82, p < 0.05, η2p = 0.11]; Affect improved in pain-related negative affect [F = 7.44, p < 0.01, η2p = 0.12], fear [F = 7.70, p < 0.01, η2p = 0.12], and distress [F = 10.87, p < 0.01, η2p = 0.16]; Well-being increased in pain mobility [F = 5.45, p < 0.05, η2p = 0.09], vitality [F = 4.54, p < 0.05, η2p = 0.07], and emotional well-being [F = 5.53, p < 0.05, η2p = 0.09] Mental health symptoms and the cognitive functioning domain did not reveal significant effects. This resilience intervention based on homeostatic self-regulation and survival strategies of survivors of extreme external environments may provide additional sociopsychobiological tools for treating individuals with chronic pain that may extend beyond treating pain symptoms to improving emotional well-being and self-growth.Clinical Trial Registration: Registered with ClinicalTrials.gov.

A new model for early diagenetic processes has been developed through a new formula explicitly accounting for microbial population dynamics. Following a mechanistic approach based on enzymatic reactions, a new model has been proposed for oxic mineralisation and denitrification. It incorporates the dynamics of bacterial metabolism. We find a general formula for inhibition processes of which some other mathematical expressions are particular cases. Moreover a fast numerical algorithm has been developed. It allows us to perform simulations of different diagenetic models (...) in non-steady states. We use this algorithm to compare our model to a classical one (Soetaert et al., 1996). Dynamical evolutions of a perturbation of particulate organic carbon (POC) input are studied for both models. (shrink)

Utviklingen innenfor informasjons- og kommunikasjonsteknologi har gitt opphav til en type etisk-politisk utfordring som gjerne kalles digital ulikhet. Tradisjonelt har det dreid seg om sosiale ulikheter i tilgangen til IKT på individnivå. Nyere forskning på området er mer opptatt av bruk og dermed av tilbudet av aktiviteter og tjenester gjennom Internett. I denne artikkelen ser vi på hvordan det kan oppstå geografisk digital ulikhet som følge av at norske kommuner tilbyr digitale tjenester – herunder informasjon og ressurser for lokalpolitisk deltakelse (...) – i svært forskjellig omfang. Det betyr at kommunene står overfor etisk-politiske utfordringer knyttet til digital ulikhet som følge av deres strategier for bruk av hjemmesider, og for digital utvikling av kommunen mer generelt. Selv om det er få kommuner som tilbyr særlig mye når det gjelder lokalpolitisk deltakelse, er ulikhetene i tilbudet av informasjon og digitale tjenester betydelige. I tillegg bidrar velutviklede hjemmesider til å gjøre kommunen mer gjennomsiktig og lettere tilgjengelig, noe vi antar er en fordel for innbyggerne. Analysen er basert på en kvantitativt orientert innholdsanalyse av hjemmesidene til alle norske kommuner og en kvalitativ innholdsanalyse av hjemmesidene til ti norske kommuner.Nøkkelord: digital ulikhet, etisk-politiske utfordringer, kommuner, hjemmesider, digitale tjenesterEnglish summary: Norwegian local governments electronically out of step? From social to geographical digital dividesThe development of information and communication technologies has raised a kind of ethical–political challenge usually referred to as a digital divide. Traditionally, this has fomented concerns about social inequalities with respect to individual access to ICT. More recent scholarship argues the need to be more focused on use rather than access; accordingly, also on the supply of activities and services through internet. In this article, we study how geographical digital divides may appear as a consequence of the fact that Norwegian local governments supply digital services – including information and resources for local political participation – to quite a different extent. This means that local governments face ethical–political challenges related to digital divides as a consequence of their strategies for the development of home pages and for digital development of local government services more generally. Even though only a few local governments offer much with regard to local political participation, the inequalities with respect to the supply of information and digital services are considerable. In addition, apparently, well–developed home pages make the local government more transparent and more accessible. We believe this to be of advantage to local citizens. The analysis is based on a quantitative content analysis of all Norwegian local governments and a qualitative content analysis of the home pages of 10 local governments. (shrink)

Way-finding (WF) is the ability to move around efficiently and find the way from a starting point to a destination. It is a component of spatial navigation, a coordinate and goal-directed movement of one’s self through the environment. In the present study, the relationship between WF tasks (route tracing and shortcut finding) and individual factors were explored with the hypothesis that WF tasks would be predicted by different types of cognitive, affective, motivational variables and personality factors. A group of 116 (...) university students (88 F.) was conducted along a route in a virtual environment and then asked first to trace the same route again, and then to find a shortcut between the start and end points. Several instruments assessing visuospatial working memory, mental rotation ability, self-efficacy, spatial anxiety, positive attitude to exploring, and personality traits were administered. The results showed that a latent spatial ability factor (measured with the visuospatial working memory and mental rotations tests) - controlled for gender - predicted route-tracing performance, while self-report measures of anxiety, efficacy, and pleasure in exploring, and some personality traits were more likely to predict shortcut-finding performance. We concluded that both personality and cognitive abilities affect WF performance, but differently, depending on the requirements of the task. (shrink)

BackgroundExercise is primarily sustained by energy derived from lipids, and glucose. Substrate utilization is the pattern by which these fuel sources are used during activity. There are many factors that influence substrate utilization. We aim to delineate the effect of exercise intensity and body composition on substrate utilization.ObjectiveThe objective of our study was to discern the differences in substrate utilization profiles during a maximal and submaximal graded exercise test, and to determine the extent to which body composition influences substrate utilization (...) during the exercise tests.MethodsA total of 27 male athletes, 32.5 ± 11 years of age, were recruited for this study. Body composition was analyzed using a bioelectrical impedance analyzer. Maximal and submaximal exercise tests were performed on a treadmill. A novel graded submaximal treadmill protocol was used for the submaximal test.ResultsAverage percent body fat was 15.8 ± 5%. Average maximal oxygen consumption was 47.6 ± 9 mL/kg/min, while the average exercise intensity at which participants were shifting to glucose predominance for energy during the maximal and submaximal tests were 76 ± 8.3% and 58.4 ± 21.1%, respectively. A paired-samples t-test was conducted to compare percent VO2max at crossover point in maximal and submaximal graded exercise tests. There was a significant difference in percent VO2max at the crossover point for maximal and submaximal tests. A linear regression was performed to elucidate the interaction between exercise intensity at the crossover point and body composition during a maximal and submaximal graded exercise test. There was a significant effect of PBF on percent VO2max at crossover point during the maximal graded exercise test [F = 9.10, P = 0.006] with an R2 of 0.245. However, there was no significant effect of PBF on percent VO2max at crossover point during the submaximal graded exercise test.ConclusionSubstrate utilization, represented by the crossover point, is dependent on the rate of increase in exercise intensity. At maximal efforts, the crossover to carbohydrates from fats as the predominant fuel source occurs at a significantly later stage of percent VO2max than at submaximal efforts. Furthermore, body composition represented by PBF is a significant predictor of substrate utilization during maximal efforts. Athletes with a relatively higher PBF are more likely to have increased lipid oxidation during high intensity exercises than those with a lower body fat percentage. (shrink)

Despite thermodynamic, bioenergetic and phylogenetic failings, the 81‐year‐old concept of primordial soup remains central to mainstream thinking on the origin of life. But soup is homogeneous in pH and redox potential, and so has no capacity for energy coupling by chemiosmosis. Thermodynamic constraints make chemiosmosis strictly necessary for carbon and energy metabolism in all free‐living chemotrophs, and presumably the first free‐living cells too. Proton gradients form naturally at alkaline hydrothermal vents and are viewed as central to the origin of life. (...) Here we consider how the earliest cells might have harnessed a geochemically created proton‐motive force and then learned to make their own, a transition that was necessary for their escape from the vents. Synthesis of ATP by chemiosmosis today involves generation of an ion gradient by means of vectorial electron transfer from a donor to an acceptor. We argue that the first donor was hydrogen and the first acceptor CO2. (shrink)

Decaying wood, while an abundant and stable resource, presents considerable nutritional challenges due to its structural rigidity, chemical recalcitrance, and low nitrogen content. Despite these challenges, certain insect lineages have successfully evolved saproxylophagy (consuming and deriving sustenance from decaying wood), impacting nutrient recycling in ecosystems and carbon sequestration dynamics. This study explores the uneven phylogenetic distribution of saproxylophagy across insects and delves into the evolutionary origins of this trait in disparate insect orders. Employing a comprehensive analysis of gut microbiome data, (...) from both saproxylophagous insects and their non‐saproxylophagous relatives, including new data from unexplored wood‐feeding insects, this Hypothesis paper discusses the broader phylogenetic context and potential adaptations necessary for this dietary specialization. The study proposes the “Detritivore‐First Hypothesis,” suggesting an evolutionary pathway to saproxylophagy through detritivory, and highlights the critical role of symbiotic gut microbiomes in the digestion of decaying wood.

This article takes stock of the project of ecological democracy, a project that has been central to debates in Environmental Values since the late 1990s. Whilst we can identify quite distinct articulations of eco-democratic thinking emerging out of the fields of green political theory, postcolonial/feminist political ecology and science studies/radical geography, it is argued that these discussions have reached something of an impasse of late following the rise of climate scepticism, authoritarian populisms and technocratic eco-modernisms. Resurgent eco-authoritarian impulses and the (...) hankering for a 'green leviathan', a climate Lenin or a 'dictatorship of the sustainment' to resolve our climate crisis make it more important than ever to affirm the need for just, rapid and democratic post-carbon transitions. The article goes on to outline how emerging discussions in radical design studies focused on redirective practice in conjunction with a revived eco-socialist focus on labour-focused political ecologies might open up different possibilities for a materialist re-grounding of ecodemocratic discussions. It is suggested that a political ecology of design embedded in public institutions, the workplace and civil society could possibleyreground a more substantive vision of ecological democracy but also allow us to think about the forms of creative labour that could drive the just transition.

Metagenomics bears upon all aspects of microbiology, including our understanding of mitochondrial and eukaryote origin. Recently, ribosomal protein phylogenies show the eukaryote host lineage – the archaeal lineage that acquired the mitochondrion – to branch within the archaea. Metagenomic studies are now uncovering new archaeal lineages that branch more closely to the host than any cultivated archaea do. But how do they grow? Carbon and energy metabolism as pieced together from metagenome assemblies of these new archaeal lineages, such as the (...) Deep Sea Archaeal Group (including Lokiarchaeota) and Bathyarchaeota, do not match the physiology of any cultivated microbes. Understanding how these new lineages live in their environment is important, and might hold clues about how mitochondria arose and how the eukaryotic lineage got started. Here we look at these exciting new metagenomic studies, what they say about archaeal physiology in modern environments, how they impact views on host‐mitochondrion physiological interactions at eukaryote origin.

This paper deals with an analysis of debris produced during the polishing of diamond. The debris is carefully collected 'as ejected' to shorten the history of the freshly removed material. Using high-resolution electron microscopy as well as electron-energy-loss spectroscopy, the structure of the material is revealed and analysed in terms of density, percentage of sp 2 hybridized carbon, and oxygen content. Debris from polishing in the so-called hard and soft directions were involved in this investigation. Overall the structure of all (...) debris is amorphous carbon. The material appears to be composed of small clusters, some nanometres in diameter, in which the graphite basal planes can be recognized. Very few and very small nanometre-sized diamond particles were found in the debris from polishing in the hard direction. The results support a polishing mechanism based on a mechanically induced transformation of diamond to graphite, after which material removal easily occurs. The well-known anisotropy observed in polishing can be explained satisfactorily on the basis of this model. Finally, in appendices, the art of polishing and the role of the black powder during preparation of the scaife are discussed. (shrink)

One way to help ensure the future of human life on the planet is to reduce the total number of people alive, as a hedge against dangers to the environment. One commentator has proposed withdrawing government and insurance subsidies from all fertile people, to help reduce the number of births. Any proposal of this kind does not, however, offer a solution commensurate with current problems of resource use and carbon emissions. Closing off fertility medicine to some people – or even (...) to all – would have only negligible effects in environmental protection. Moreover, the proposal to withdraw financial subsidies from fertile people would have prejudicial effects on lesbian and gay people, who must always reach beyond their same-sex relationships for help in having children. It is, moreover, entirely unclear why some people turning to fertility medicine for help in having children should have to pay their own way even though they contribute to the pool of money available for government and insurance subsidies. Entitlements based on an alleged moral difference between the ‘fertile’ and the ‘infertile’ cannot support such a conclusion. (shrink)

This essay comments on some accomplishments and future challenges concerning research and teaching in social issues. The author chaired the All-Academy of Management Task Force on Ethics. The SIM Division’s role is to examine critically the suitability of the actions and policies of business managers, organizations (mostly business firms), and the free market system itself. The scope of inquiry covers ethics, governance of organizations, and stakeholders. The emphasis in that inquiry is on the benefits and harms to people from businesses (...) and the market system. Three major issues deserve our examination: 1) the growing influence of the global corporation, 2) global climate change and the negative environmental impact of our lifestyles, and 3) the moral maturity or lack thereof of contemporary decision makers and citizens. Corporations have immense influence, reflected in the growing role of lobbying. Environmental degradation is one of the most serious problems that face people of our ever smaller planet, so it challenges us to examine our lifestyles and the carbon footprint of our actions. We are now able to research and teach the development of good moral habits (virtues) and character. (shrink)

The quest for ecological sustainability—specifically via prioritizing degrowth—creates significant, often overlooked challenges for the chronically ill. I focus on type-1 diabetes, treatment for which depends on nonrenewables and materials implicated in the global proliferation of toxins that harm biospheric functions. Some commentators suggest obliquely that seeking to develop ecologically sustainable treatments for type-1 shouldn’t be prioritized. Other medical concerns take precedence in a post-carbon world marked by climate change and widespread ecological devastation. I challenge this view on three grounds. Its (...) proponents (i) fail to treat type-1 as the public health issue it is, particularly within the context of what Sunaura Taylor calls disabled ecologies. They (ii) deny persons with type-1 an equal opportunity to pursue survival. And they (iii) presume without warrant that treating type-1 is an all-or-nothing affair. Indeed, research by biohackers points to suboptimal but potentially workable ways to make type-1 survivable in a post-carbon future—so long, I stress, as their findings are cripped in a manner that foregrounds the demands of environmental justice.
