Modern societies are simultaneously confronting demographic collapse and intensifying conflicts over gender equality, care, and labor. These tensions are often treated as policy trade-offs, yet they stem from a deeper ontological limitation: the reduction of human existence to functional structure (E≈S). This paper introduces Universal Phase Crystallization Theory (UPCT) as a foundational shift toward defining existence as generative resonance (E=ΦR). By reframing freedom, equality, and ethics as dynamic conditions of generative participation, the apparent conflict between demographic policy and gender equality dissolves. What emerges is not a compromise, but a civilizational transition from function-centered systems to generation-centered structures. This work provides a unified theoretical framework for rethinking equality, care, and sustainability in the 21st century. Highlights Reveals that conflicts between demographic policy and gender equality originate from a shared S-centric ontology (E≈S) Introduces UPCT (E = ΦR) as a unified framework for redefining existence, equality, and ethics Reconstructs equality as non-comparability of generative potential, beyond functional parity Demonstrates that demographic decline is a systemic failure of generative continuity (d(ΦR)/dt<0) Proposes a civilizational redesign based on generative resonance rather than labor-market optimization Summary & Main Arguments 1. Ontological Diagnosis of Modern CrisisThis paper begins by identifying a foundational contradiction in modern societies: the persistent conflict between demographic sustainability and gender equality. Rather than interpreting this as a policy failure, the paper argues that the root cause lies in an implicit ontological assumption—namely, that human existence is reducible to structural or functional representation (E≈S). Within this framework, individuals are treated as economic actors, legal units, or measurable entities, leading to systemic tensions when biological, relational, and generative dimensions cannot be fully captured. 2. Historical Saturation of Functional EqualityTracing the evolution of equality from formal legal equality to distributive and identity-based equality, the paper demonstrates that modern equality has progressively intensified its reliance on functional comparability. While these developments have been historically emancipatory, they culminate in a paradox: the more equality is pursued through structural comparison, the more differences (biological, genetic, relational) become sources of conflict. This results in a zero-sum system that ultimately fragments social cohesion. 3. UPCT as Ontological ReframingTo resolve this impasse, the paper introduces Universal Phase Crystallization Theory (UPCT), which redefines existence as generative resonance (E=ΦR). Here, Φ represents generative potential, and R relational resonance. Structure (S) is not the essence of existence but a temporary crystallization within a dynamic generative cycle (Φ→R→S→Φ′). This reframing shifts the analytical focus from static structure to dynamic process. 4. Redefinition of Core ValuesWithin the UPCT framework, the foundational concepts of modern philosophy are reinterpreted. Freedom becomes participation in generative processes rather than choice within structures. Equality is redefined as the non-comparability of generative potential rather than functional uniformity. Ethics is formalized as the sustainability condition (d(ΦR)/dt≥0), transforming it from normative prescription to systemic viability condition. 5. Policy Implications and Civilizational TransitionFinally, the paper applies this framework to the conflict between demographic policy and gender equality. It demonstrates that the conflict dissolves when both are reinterpreted through generative conditions rather than structural distribution. Policy interventions—such as reducing structural burdens, restoring relational infrastructure, elevating care, and redesigning time—are reframed as foundational requirements for sustaining generative resonance. This marks not a policy adjustment, but a civilizational transition. Contributions 1. Ontological Regrounding of Social TheoryThis paper provides a fundamental ontological critique of modern social theory by identifying the implicit equation E≈S as the root of contemporary contradictions. By introducing E=ΦR, it establishes a new foundation that integrates process, relation, and generation into the definition of existence. 2. Unified Framework Across DisciplinesThe study bridges philosophy, economics, gender studies, and systems theory by offering a single conceptual framework capable of explaining demographic decline, care crises, and equality conflicts. This integration moves beyond fragmented disciplinary approaches. 3. Redefinition of Equality and EthicsA major theoretical contribution is the redefinition of equality as non-comparability and ethics as a dynamic sustainability condition. This resolves long-standing tensions between fairness, difference, and viability, offering a new paradigm for justice theory. 4. Reinterpretation of Feminist and Critical ThoughtRather than rejecting feminist, Marxist, or care-based critiques, the paper demonstrates how these traditions can be sublated within UPCT. It preserves their insights while extending them beyond structural limitations, avoiding both reductionism and opposition. 5. Civilizational Design FrameworkThe paper advances a practical theoretical model for societal redesign. By translating UPCT into policy principles—structural reduction, relational recovery, generative elevation, and temporal redesign—it provides a concrete pathway for transitioning toward a generative society.

Abstract Decentralized finance (DeFi) platforms have gained in popularity over the last few years, as they offer a wide range of accessible, innovative, and complex financial services. Because they evolve quickly under limited regulation, it is easy for malicious parties to target them for profit when they notice a vulnerability in these emergent protocols. Existing work has focused on understanding typical attack flows and securing the technology to alleviate crime. However, little is known about what other attributes, beyond technical vulnerabilities, may put DeFi actors at risk. Drawing on Cook’s (Crime Justice 7:1–27, 1986) crime opportunity framework of target attractiveness, this study investigates which attributes are associated with an increase or a decrease in the likelihood of DeFi victimization. We compare actors victimized in 2022 with those that were not across several target dimensions: propinquity, vulnerability, potential payoff, main area of operation, and self-protection activities. Results show that being listed on a popular centralized exchange, operating on a layer-2 blockchain, offering lending services, and having high trading volumes are associated with an increased likelihood of victimization, while operating a dApp and having experienced past victimization are associated with a decrease. By contrast, self-protection measures such as publicly disclosed audits, and bug bounty programs show no measurable effect, likely reflecting variation in their quality and implementation or the fact that undisclosed audits could not be observed. By integrating criminological theory into DeFi security research, this study provides a holistic framework for understanding crime opportunities in this novel ecosystem, while informing potential prevention strategies to reduce associated harms.

Abstract Industry 4.0 technology enables luxury fashion brands in the virtual market to quantify the value of digital items in the metaverse; thus, brands can maintain their reputations, ensure consistent and integrated luxury brand marketing, and attract new consumers in the virtual market. Understanding consumer behavior toward buying digital assets (i.e., nonfungible tokens [NFTs]) is important. By using blockchain‐based NFTs as a way to verify the authenticity of digital assets in the virtual market, luxury brands can maintain their reputations and help consumers protect their digital assets. Thus, developing global marketing strategies supported by this technology is important for the success of luxury fashion brands in the metaverse. We conducted analyses to explore consumer behavior in the metaverse with regard to blockchain‐based luxury NFTs. The findings reveal the psychological evaluation process as a mechanism that drives consumer behavior toward NFT luxury brand fashion items in global virtual markets. The empirical findings also extend the application of game theory and prospect theory by revealing the psychological evaluation of risks associated with (not) buying luxury fashion NFTs as another mechanism driving consumer behavior in the metaverse.

Bill Hamilton was always at his best in small groups, and I would like to open and close my reflections with some thoughts generated by two small scientific meetings that Bill Hamilton attended. I was not present at the first meeting, in Tvarminne, Finland, but a photograph from the meeting made an impression on me. In the foreground stood Pekka Pamilo, the organizer of the meeting, with a rather worried expression on his face. In the background was Bill Hamilton, skating across the ice. Bill had brought his ice skates, intent on taking every advantage of this visit to the north. It turned out, however, that the ice was quite thin, so the organizers attempted to dissuade Bill. They made a general request that speakers at the meeting should please not attempt any ice skating, at least until after they had delivered their talks. Bill followed the letter of this request, but did not follow its spirit. After giving his talk, he donned his skates and set off. This picture brought to mind all sorts of associations. How can one not remember J. B. S. Haldane's musings about being willing to rescue two drowning brothers, or eight cousins. I hope Pekka will forgive me if I try to imagine his thoughts about the possibility of Bill falling though the ice. “ Well, I do not think I am related to him... On the other hand, everyone in Finland is more or less related! But then, he is not from Finland, is he? Still, we may not share many genes, but we do share a great many memes.” The other thought that comes to my mind is one that has been noted frequently since Bill's recent death from malaria. Bill Hamilton was a risk taker, not just in his life, but also in his science. In his work, too, he sometimes skated on thin ice, traveling where others would not. E. O. Wilson once used exactly this metaphor to describe a certain kind of scientist who is always drawn to the dangerous or to the forbidden: “They are the taboo breakers who enjoy the whiff of grapeshot and the crackle of thin ice” (Wilson, 1978: 283). When Bill skated on thin ice in Finland, the results were satisfactory: the ice may have crackled but it did not give way. When he skated on thin scientific ice, the results were usually not just satisfactory, but glorious. Bill Hamilton's most glorious ideas were kin selection and inclusive fitness. Talking about Hamilton's contributions to inclusive fitness is a bit like talking about Isaac Newton's contributions to dynamics or Charles Darwin's contributions to natural selection. He invented the idea, and he developed most of its important implications. There were some forerunners, as there always are in science. I think of Hamilton's contribution as a fusing of two traditions. First, there was population genetics. Hamilton didn't completely invent the idea of kin selection. The idea was foreshadowed by Haldane (1955), Fisher (1958), and Williams (Williams and Williams, 1957). However, none of them developed it in any detail, perhaps because they did not appreciate its general importance in nature. For that we can thank animal behaviorists, particularly those like Wynne-Edwards (1962) and Emerson (1960), who believed that cooperation was very common in nature. Bill neatly hybridized the two traditions. If cooperation and altruism were important in nature, then we needed an explanation that was consistent with population genetics, and so inclusive fitness was born. Hamilton was well suited to make this match. Those acquainted with Hamilton only through his best-known papers may think of him as a theoretician and might conclude that he had the theoretician's superficial knowledge of the natural world. But in fact it was his mathematical skills that were hard won, while as a natural historian he was, well, a natural. You can see evidence of this in many of his papers, but it comes out particularly in his lesser known papers on insects under bark (Hamilton, 1978) and on fig wasps (Hamilton, 1979). So was Hamilton's contribution a simple merging of the insights of an ethologist and a population geneticist? No, it wasn't that simple, for several reasons. First, there was a lot of thin ice between these areas, and skating from one to the other was not encouraged in the early 1960s. Geneticists were leery of anything that smacked of eugenics. That included any application of population genetics to behavior. It included most of all applications to understanding social behavior, something we have always been a little touchy about. If nature was nasty, rude, or bawdy, better not to know about it, let alone let the public know. Let me illustrate the idea in an unconventional way, with a bit of verse that I call “Family Values”: Would I jump in a lake To save my drowning cousin? It's not a risk I'd take For him plus half a dozen. But if you raise the stake And make the prize my brother? Now that's a deal I'll make... If you'll just toss in another. If this poem, and the Haldane quip it is based upon, elicit chuckles, it is in large part because they treat a topic that is uncomfortable for us. Most humor is built on discomfort of one form or another. In this case, we recognize that we make unconscious judgments akin to these, with awkward balances of self-interest and family interest, but we don't like to see ourselves as calculating self-servers. Now throw in a good dash of genetics, and the mixture becomes truly taboo. Perhaps that's why Haldane and others did not pursue the topic. Bill's recollections of his graduate career (Hamilton, 1996) describe the price that he paid for his desire to be where the ice is thin. He had difficulty finding advisors. He had no desk. He had no invitations to talk about his work. It was not even clear that his thesis work, which would produce some of the most heavily cited papers in evolutionary biology (Hamilton, 1964a,b), would be acceptable for a Ph.D. For someone who was not socially outgoing in the first place, the effect of this isolation was severe. He feared that he might be a crank; why else would all these manifestly smart people fail to see the interest in what he was doing? He took to working in train stations and public parks simply to have some minimal level of human interaction. Mary Jane West Eberhard made a telling point in her talk about Bill at a recent meeting (West-Eberhard, 2000). She noted that Bill's life serves as a counter-example to those critics who said that sociobiological knowledge was dangerous. He was proof that one can see all that is grim in the depths of our nature and still live a life of decency and kindness. Bill would have been uncomfortable with hagiography. His writings allude to a knowledge of the dark side of human nature, obvious to him through introspection, so clearly his thoughts were not always saintly. But whatever dark thoughts swirled in his mind, on the surface—and this is where it counts—he was basically a gentle man. Despite his highly critical mind, I never heard him criticize anyone in anything but the kindest, most self-effacing manner. He did not judge people by credentials and had time for people that others might consider to be amateurs or even crackpots, George Price being a notable example. And while he no doubt appreciated the recognition he eventually received, particularly given his lonely days as a graduate student, he did not seem to crave recognition excessively. Dawkins reported one example where Bill gave credit to someone else for an idea that was really his own and had to be confronted with the evidence from his own paper (Dawkins, 2000). Then, as Dawkins described it with an adverbial tour de force, Bill “ eeyorishly” admitted that, yes, he'd had the idea, but the other fellow had put it much better. I can give another small illustration from my own experience. In 1985 I published a paper using Price's rule to obtain a new expression for inclusive fitness (Queller, 1985). Alan Grafen then chided me (Grafen, 1985), quite rightly, for having neglected to cite Hamilton's paper using Price's rule (Hamilton, 1970). My only excuse is that Bill had read my paper in manuscript without ever pointing out the omission, which he must have noticed. For that matter, I had learned about Price's rule directly from Bill in seminars at the University of Michigan. If I remembered Price's rule well and forgot Bill's uses of it, it is partly because of the selfless way that Bill taught the subject. There is a another reason that Hamilton's contribution cannot be viewed as a simple merging of naturalist and theoretical traditions. He did not just come up with any old theoretical model. For example, one could model the evolution of altruism for some particular limited set of conditions (George and Doris Williams had already done this; Williams and Williams, 1957), but then one has to wonder how general the conclusions are. And it is also possible, as other modelers later showed, to add so many mathematical bells and whistles that we lose track of the general theme. In contrast, what Hamilton came up with was a theory that was not only basically true, but also beautiful and elegant. I'm not speaking of the mathematical derivation in his 1964 paper, which was actually rather gruesome. I'm speaking of the result, what has come to be known as Hamilton's rule. It is so simple that even a non-mathematical mind can easily understand it and wield it, and so general that it can often be applied to new social evolution problems without any fresh mathematical modeling. How was this simple elegance achieved? I think there are two main reasons. First, Hamilton was willing to make assumptions that allowed the result to be simple without seriously compromising the biology. For example, he assumed that selection would be weak. Stronger selection has the effect of distorting the relatednesses away from their familiar values, and it makes them dependent on genetic details such as dominance. Hamilton's assumption was justified because weak selection is presumably common. For that matter, it's probably not so bad an approximation for stronger selection. A little distortion of correlation coefficients doesn't matter too much to someone interested in the real world, where estimates of parameters are typically only good to about one significant digit anyway. The second reason inclusive fitness is so useful is its inversion of fitness calculation methods. Instead of grouping together all effects of others on x's fitness, it calculated all the inclusive effects of x on others' fitnesses. This actor-centered approach is what makes the method so easy to apply. In Hamilton's own words: “The social behaviour of a species evolves in such a way that in each distinct behaviour-evoking situation the individual will seem to value his neighbors' fitness against his own according to the coefficients of relationship appropriate to the situation” (Hamilton, 1964b: 19). It has become clear in recent years that the same behaviors can also often be understood as a form of group selection—not the old group selection of Wynne-Edwards, but nevertheless a method that involves partitioning of selection into within-group and between-group components (see Sober and Wilson, 1998). But the fact remains that almost no one uses these methods much to think about and solve interesting problems. Each of the two methods can dissect social evolution into component parts, but where inclusive fitness divides nature neatly at the joints, other methods seem to hack clumsily through the long bones. Inclusive fitness and kin selection were important on several levels. First, of course, they provided an explanation for the evolution of altruism. We still don't know whether Hamilton's famous haplodiploid hypothesis, based on three-quarters relatedness (Hamilton, 1964b, 1972), explains the origin of eusociality. But it seems certain that the answer does lie within his more general framework of relatedness, costs, and benefits. For the study of social insects, another result of inclusive thinking was perhaps even more interesting. The theory did not simply explain the altruism that we already knew about. It also predicted something we did not know much about: conflicts within colonies. Because inclusive fitness interests often differ even among close relatives (Hamilton, 1972), there can be conflicts over who should be queen, conflicts over who should lay the male-destined eggs, and conflicts over sex ratios (reviewed in Queller and Strassmann, 1998). Studies in these areas have amply satisfied the requirement that a good theory should not just explain what is known, but also make novel and successful predictions. I think a parallel phenomenon occurs in the world beyond social insects. Perhaps even more important than the explanation of altruism itself was the general validation given to selfish gene models. If selfish genes are to be of any value in explaining the evolution of social behavior, they simply must be able to explain the cases where the behavior is not phenotypically selfish. Otherwise the method must be counted as a failure. So kin-selected explanations of altruistic behavior gave life to selfish gene explanation in areas where kinship was not paramount. Hamilton's own work clearly shows this. He didn't stop with altruism. He made pioneering contributions in many other areas. The accompanying pieces in this issue describe his contributions to the study of sexual selection and parasites, but his work also included important contributions to senescence theory (Hamilton, 1966), sex ratios (Hamilton, 1967), selfish herds (Hamilton, 1971), dispersal (Hamilton and May, 1977), tit-for-tat cooperation (Axelrod and Hamilton, 1981), and within-individual conflict (Hamilton, 1967). This truly formidable list of accomplishments, and the whole selfish gene tradition of which it is a part, emerged from a confidence based on Hamilton's success in solving the potentially fatal problem of altruism. Finally, in recent years it has become increasingly clear that a theory of altruism and cooperation is important for a much grander reason than solving the annoying puzzle of the social insects. It is also needed to explain a much more pervasive kind of cooperation; the evolution of the organism itself (Maynard Smith and Szathmáry, 1995) why do cells cooperate in a body? Why do formerly independent bacteria evolve into organelles? How did replicators get together in the first place? Organisms, though they compete selfishly with each other, are themselves cooperative entities. Cooperation is therefore fundamental to all of life. I began with a small scientific meeting in Finland. Let me close with another one, in Castiglioncello, Italy. The highest scientific compliment I have ever received was one that Bill delivered there, actually to my wife and collaborator Joan Strassmann. Bill had, many years previously, done field work in Brazil on the troubling question of how sociality could be maintained in wasps with many queens. We had recently helped show, with molecular tools that had not been available to Bill, how relatedness was kept at levels consistent with kin selection (Queller et al., 1988, 1993; West Eberhard, 1978). What he said to Joan was “Now I will have to think up a different question to ask St. Peter when I meet him.” Of course, this was ridiculously inflated praise, a reflection of Bill's generosity rather than his acumen. He was no doubt signaling this exaggeration by his use of the religious reference, since Bill did not seem to be a conventionally religious man. Instead, he is some one who saw his afterlife more in terms of burying beetles (Hamilton, 2000) than in terms of meeting St. Peter. Still, I'd like to run with idea for just a moment. In the sad days after Bill died, the thought of him interrogating St. Peter gave me a certain amount of solace, and perhaps even pleasure. It's not that I can imagine what Bill's question was. Nor was it the thought of him receiving a satisfactory answer. Instead, what appeals to me is the impact on old St. Peter. I imagine him at first flummoxed because he couldn't answer the question, then annoyed because he had never thought of it himself, and finally intrigued by the implications. I imagine him spending his free moments over the next few centuries thinking about it, making new observations on the teeming life below, scribbling some population genetic equations in the margins of his heavenly register, and perhaps running some simulations on God's fastest supercomputer. Perhaps I overestimate St. Peter's curiosity, but Bill's questions have always had that kind of effect. That they will long continue to do so is his legacy to us.

In this article, we propose a comprehensive conception of what personality traits are and what they mean in lay personology. Our conception is a pragmatic one that relies on the ecological concept of affordance and the theory of dual knowledge. It is not based on the same knowledge-building process as other pragmatic conceptions in that it distinguishes evaluative knowledge, produced by the generalization of affordances, from descriptive knowledge, deemed to be of limited importance in trait usage. It posits that an essential component of the meaning of traits is how others act towards the persons who possess these traits. We present a compilation of ten experimental studies in various areas of interest (statistical studies of trait/behavior associations, semantic decision-making, person memory, judgments at zero acquaintance) to prove the importance of the evaluative component composed of others' behaviors (OBs). These experiments show that the evaluative component 1. includes a repertoire of behaviors that is just as reliable for encoding traits as the repertoire of behaviors ascribed to the target; 2. can be just as accessible as the descriptive component for highly evaluative traits; 3. is very powerful in structuring mental representations of persons; 4. is more highly activated in social contexts, especially in workevaluation situations, and 5. is more discriminative than the descriptive component in immediate appraisals of persons.
