I relate plural quantification, and predicate logic where predicates do not need a fixed number of argument places, to the part-whole relation. For more on these themes see later work by Boolos, Lewis, and Oliver & Smiley.

“자기 존재 유지의 노력”(코나투스)은 스피노자의 사상을 “긍정의 철학”으로 규정하게 해 온 핵심 개념이다. 그러나 코나투스는 인간을 예속적이고 심지어 자기 파괴적인 삶으로 몰아가기도 한다. 이것이 모순되어 보인다면 이는 코나투스를 흔히 단순체의 관점에서 보기 때문이다. 나는 스피노자에게서 모든 개체가 복합체인 만큼 코나투스 역시 복합적임을, 그리고 이 복합성은 부분의 다수성이나 전체 구조의 복잡성보다 더 역동적인 갈등적 성격을 가짐을 보여준다. 더 구체적으로는 첫째, 코나투스가 내적 부정을 겪을 수 있으며, 이는 둘째, 전체로서의 개체만이 아니라, 개체의 변용들에도 별도의 코나투스가 있고, 후자의 자기 긍정성이 개체 전체의 본성에 (...) 상반될 수 있기 때문이다. 곧 변용의 상대적 독립성이 개체의 자기 파괴적 행위의 원인이다. 하지만 이 독립성은 변용의 자체적 힘보다는 개체들 간의 복합적 연관에 바탕을 두는 한에서, 자유의지에 기대지 않고 개체의 역량을 강화할 수 있는 조건이기도 하다. 결국 코나투스의 복합성을 제시함으로써 나는 우리 안에서 일어나는 긍정과 도약의 느낌을 우리 자신의 능동성으로 착각해서는 안 되며, 이 느낌 역시 원인을 통해 인식되어야 함을 환기시킨다.

The economic crisis is also a crisis for economic theory. Most analyses of the evolution of the crisis invoke three themes, contagion, networks and trust, yet none of these play a major role in standard macroeconomic models. What is needed is a theory in which these aspects are central. The direct interaction between individuals, firms and banks does not simply produce imperfections in the functioning of the economy but is the very basis of the functioning of a modern economy. (...) This book suggests a way of analysing the economy which takes this point of view. The economy should be considered as a complex adaptive system in which the agents constantly react to, influence and are influenced by, the other individuals in the economy. In such systems which are familiar from statistical physics and biology for example, the behaviour of the aggregate cannot be deduced from the behaviour of the average, or "representative" individual. Just as the organised activity of an ants’ nest cannot be understood from the behaviour of a "representative ant" so macroeconomic phenomena should not be assimilated to those associated with the "representative agent". This book provides examples where this can clearly be seen. The examples range from Schelling’s model of segregation, to contributions to public goods, the evolution of buyer seller relations in fish markets, to financial models based on the foraging behaviour of ants. The message of the book is that coordination rather than efficiency is the central problem in economics. How do the myriads of individual choices and decisions come to be coordinated? How does the economy or a market, "self organise" and how does this sometimes result in major upheavals, or to use the phrase from physics, "phase transitions"? The sort of system described in this book is not in equilibrium in the standard sense, it is constantly changing and moving from state to state and its very structure is always being modified. The economy is not a ship sailing on a well-defined trajectory which occasionally gets knocked off course. It is more like the slime described in the book "emergence", constantly reorganising itself so as to slide collectively in directions which are neither understood nor necessarily desired by its components.

Extended staying alive theory (SAT) raises the issue of the extent to which its various attributes are linked or whether they provide alternative means to the same adaptive ends. Theories such as SAT that consider an array of sex differences may benefit from the application of the multivariateDstatistic, rather than using a series ofdvalues, as is common at present.

The evolution of complex life forms, such as multicellular organisms, is the result of a number of evolutionary transitions in individuality (ETIs). Several attempts have been made to explain their origins, many of which have been internalist (i.e., based largely on internal properties of these life form's ancestors). Here, we show how an externalist perspective, via the ecological scaffolding model in which properties of complex life forms arise from an external scaffold, can shed new light on the question (...) of ETIs. Ultimately, we anticipate progress in the field will occur by recognizing the importance of both the internalist and externalist modes of explanation for ETIs. We illustrate this by considering an extension of the ecological scaffolding model by niche construction in which particles modify the environment which later becomes the scaffold giving rise to collective-level individuality.

Fractal patterns offer one way to represent the rough complexity of the natural world. Whilst they dominate many of our visual experiences in nature, little large-scale perceptual research has been done to explore how we respond aesthetically to these patterns. Previous research (Taylor et al., 2011) suggests that the fractal patterns with mid-range fractal dimensions have universal aesthetic appeal. Perceptual and aesthetic responses to visual complexity have been more varied with findings suggesting both linear (Forsythe et al., 2011) and curvilinear (...) (Berlyne, 1970) relationships. Individual differences have been found to account for many of the differences we see in aesthetic responses but some, such as culture, have received little attention within the fractal and complexity research fields. This 2-study paper aims to test preference responses to fractal dimension and visual complexity, using a large cohort (N=443) of participants from around the world to allow universality claims to be tested. It explores the extent to which age, culture and gender can predict our preferences for fractally complex patterns. Following exploratory analysis that found strong correlations between fractal dimension and visual complexity, a series of linear mixed-effect models were implemented to explore if each of the individual variables could predict preference. The first tested a linear complexity model (likelihood of selecting the more complex image from the pair of images) and the second a mid-range fractal dimension model (likelihood of selecting an image within mid-range). Results show that individual differences can reliably predict preferences for complexity across culture, gender and age. However, in fitting with current findings the mid-range models show greater consistency in preference not mediated by gender, age or culture. This paper supports the established theory that the mid-range fractal patterns appear to be a universal construct underlying preference but also highlights the fragility of universal claims by demonstrating individual differences in preference for the interrelated concept of visual complexity. This highlights a current stalemate in the field of empirical aesthetics. (shrink)

For a long time, linguists more or less denied the existence of individual differences in grammatical knowledge. While recent years have seen an explosion of research on individual differences, most usage-based research has failed to address this issue and has remained reluctant to study the synergy between individual and community grammars. This paper focuses on individual differences in linguistic knowledge and processing, and examines how these differences can be integrated into a more comprehensive constructionist theory of grammar. The examination is (...) guided by the various challenges and opportunities that may be extracted from scattered research that exists across disciplines touching on these matters, while also presenting some new data that illustrate how differentiation between individuals can improve models of long-term language change. The paper also serves as the introduction to this special issue of Cognitive Linguistics, which collects seven contributions from various linguistic disciplines focusing on key aspects of individuals’ grammars.

The aim of this work is to study complex ecological models exhibiting simple dynamics. We consider large scale systems which can be decomposed into weakly coupled subsystems. Perturbation Theory is used in order to get a reduced set of differential equations governing slow time varying global variables. As examples, we study the influence of the individual behaviour of animals in competition and predator-prey models. The animals are assumed to do many activities all day long such as searching for food (...) of different types. The degree of competition as well as the predation pressure are dependent upon these activities. Preys are more vulnerable when doing some activities during which they are very exposed to predators attacks rather than for others during which they are hidden. We study the effect of a change in the average individual behaviour of the animals on interspecific relationships. Computer simulations of the whole sets of equations are compared to simulations of the reduced sets of equations. (shrink)

Individuation and organization in complex living multi-level ecosystem occurs as dynamical processes from early ontogeny. The notion of living “holon” displaying dynamic self-assertion and integration is used here to explain the ecosystems dynamic processes. The update of the living holon state according to the continuous change of the dynamic system allows for its viability. This is interpreted as adaptation, selection and organization by the human that observes the system a posteriori from its level. Our model concerns the complex (...) dynamics of the adaptive immune system, integrating holon-lymphocytes that collectively preserve the identity and integrity of the organism. Each lymphocyte individualizes as a dynamic holon-lymphocyte, with somatic gene individuation leading to an individual, singular antigen immunoreceptor type, promoting the self-assertion. In turn, the “Immunoception” allows for perception of the environmental antigenic context, thus integration of the holon in its environment. The self-assertion/integration of holon-lymphocyte starts from fetal stages and is influenced by mother Lamarckian acquired historicity transmissions, a requisite for the integrity of the holobiont-organism. We propose a dynamic model of the perception by holon-lymphocyte, and at the supra-clonal level of the immune system functions that sustain the identity and integrity of the holon-holobiont organism.

In this article, I will discuss possible differences between ecosystems and organisms on the basis of their intrinsic complexity. As the concept of complexity still remains highly debated, I propose here a practical and original way to measure the complexity of an ecosystem or an organism. For this purpose, I suggest using the concept of logical depth (LD) in a specific manner, in order to take into account the difficulty as well as the time needed to generate the studied object. (...) I illustrate this method with fully controlled Daisyworld simulations (i.e., simulations based on the Gaia hypothesis) that have often been proposed to mimic living systems. The method consists of the following sequential stages: (1) identification of the shortest program able to numerically model the studied system (also called the Kolmogorov–Solomonoff complexity); (2) running the program, once if there are no stochastic components in the system, several times if stochastic components are there; and (3) computing the time needed to generate the system with LD complexity. This measure is supposed to estimate the system complexity. It appears in this study that LD estimations fit well with the intuition we have of complex systems, with higher complexities being found for more realistic Daisyworlds. With such a method of capturing the time needed to build a system, we expect to detect in future studies any quantified differences between complex ecosystems and organisms. (shrink)

In this paper we examine the question of whether complexity-like explanations can be applied to the psychology of individuals, and its implications for the scope of complexity explanations of social phenomena. We start by outlining two representational-cum-computational models of the mind—a symbolic model and a networks or connectionist one—and their pros and cons. Based on this we then outline a radical, non-representational and non-computational alternative model that has been gaining ground recently, and which has significant affinities with complexity explanations (...) in social science. Deploying neo-Kantian considerations, we then argue that due to the discursivity, or conceptual dimension of our cognitive system, the radical alternative must be incorrect insofar as humans are concerned. Indeed, human psychology must involve, at least partly, a representational understanding of the sort provided by the symbolic model. Relatedly, we show how the discursiviry of human cognition complicates our psychology and makes it difficult to account for. Finally, we briefly address the question of how the complicated nature of individual psychology, implied by human discursivity, may affect complexity explanations of social behavior. (shrink)

Understanding individual differences in cognitive performance is an important part of understanding how variations in underlying cognitive processes can result in variations in task performance. However, the exploration of individual differences in the components of the decision process—such as cognitive processing speed, response caution, and motor execution speed—in previous research has been limited. Here, we assess the heritability of the components of the decision process, with heritability having been a common aspect of individual differences research within other areas of cognition. (...) Importantly, a limitation of previous work on cognitive heritability is the underlying assumption that variability in response times solely reflects variability in the speed of cognitive processing. This assumption has been problematic in other domains, due to the confounding effects of caution and motor execution speed on observed response times. We extend a cognitive model of decision‐making to account for relatedness structure in a twin study paradigm. This approach can separately quantify different contributions to the heritability of response time. Using data from the Human Connectome Project, we find strong evidence for the heritability of response caution, and more ambiguous evidence for the heritability of cognitive processing speed and motor execution speed. Our study suggests that the assumption made in previous studies—that the heritability of cognitive ability is based on cognitive processing speed—may be incorrect. More generally, our methodology provides a useful avenue for future research in complex data that aims to analyze cognitive traits across different sources of related data, whether the relation is between people, tasks, experimental phases, or methods of measurement.

In dementia research evidence is mounting that therapeutic strategies that target moderate and even mild Alzheimer's disease may be missing the ‘therapeutic window’. Given that the neuropathology that leads to Alzheimer's disease probably begins somewhere between 10 and 15 years before symptoms manifest, many believe that the optimal therapeutic strategy would target persons in the earliest phases of disease development or even earlier. This would include, for example, persons with prodromal Alzheimer's and even persons who are deemed at risk. Given (...) the nature of research involving the central nervous system, it is conceivable that some therapeutic investigations may involve an increase over minimal risk. This paper examines how, in dementia research, at-risk persons, although healthy, bring multiple and intersecting vulnerabilities to the prospect of research participation even though they are clinically healthy. Current guidelines for research ethics may not provide adequately for the nuances of ‘healthy individuals’ and their possible vulnerabilities. In the context of neurodegenerative disease, the fact of being ‘at risk’ alters the vulnerability profile in significant ways. While healthy persons who are at risk of developing dementia may not appear to warrant placement in the research category of vulnerable participants (alongside prisoners, pregnant women and children) careful regard for the vulnerabilities that arise as a result of the intersecting circumstances of being healthy and at risk of an incurable disease are worthy of increased attention and consideration, particularly as the research effort for the increasingly prevalent disease of Alzheimer's moves forward.

The ArgumentMany associations have recently been discovered between phenotypic variation and genetic loci, causing some to advocate what Robert Sinsheimer has called “a new eugenics” that would treat genetic “defects” in individuals prone to a disease. The first premise of this vision is that genetic association studies reveal the biological cause of the phenotypic variation. Once the responsible genes are known, the second premise is that we should focus upon changing “nature” rather than “nurture” by correcting the “defective” genes.The (...) first premise is flawed because associations between genetic markers and phenotypes can be spurious, as shown by an example. Moreover, it is shown that using non-causative but associated genetic markers one at a time (the normal practice) can lead to incorrect predictions of disease risk for many individuals. Going from association to causation is a non-trivial step scientifically that has rarely been done in much of the human genetic research.Even when a particular locus does contribute to the phenotypic variation of interest, the first premise remains flawed because phenotypes in general arise from complex interactions among genes and between genes and environments as shown for genes associations with coronary artery disease (CAD). The ability of current molecular genetic tools to “fix” defective genotypes is extremely limited, but even if the technological problems could be overcome, the studies on CAD reveal no obvious “defective” gene to fix because the genetic effects are so context dependent (upon both other genes and environmental factors). Contrary to the second premise of the new eugenics, the more we learn about how different genotypes show variable responses to environments, themoreimportant the environment becomes for individual treatment.The paradigm of a “defective gene” may work for classical Mendelian genetic diseases that are due to loss-of-function mutations. However, such mutations affect only a small portion of humanity. When the focus is changed to common disease and behavioral phenotypes, the “defective gene” paradigm is biologically meaningless and often harmful when applied to individuals. Thus, even when genes clearly do influence common phenotypic variation, the premises of the “new eugenics” are biologically indefensible. (shrink)

Complex life cycles are common in the eukaryotic world, and they complicate the question of how to define individuality. Using a bottom-up, gene-centric approach, I consider the concept of fitness in the context of complex life cycles. I analyze the fitness effects of an allele on different biological units within a complex life history and how these effects drive evolutionary change within populations. Based on these effects, I attempt to construct a concept of fitness that accurately predicts (...) evolutionary change in the context of complex life cycles. (shrink)

Background Individuals living with multimorbidity and/or mental health issues, low education, socioeconomic status, and polypharmacy are often called complex patients. The complexity of their health and social care needs can make them prone to disease burden and suffering. Therefore, they frequently access health care services to seek guidance for managing their illness and suffering. Aims The aim of this research was to describe the approaches used by nurses to alleviate the suffering of individuals with multimorbidity and (...) class='Hi'>complex needs in acute care settings. Research Design A qualitative descriptive approach. Participants and Research Context Semi-structured interviews were conducted with 19 nurses working in general, medical-surgical, specialized, and intensive care settings across five hospitals in Pakistan. Reflexive thematic analysis was used for analysis. Ethical Considerations Ethical approval was obtained from the Ethical Committee of Al-Nafees Medical College Islamabad, Pakistan. Findings Four themes were generated: Deeper Exploration of Patients’ Health-Illness Situation and Complexity, Prioritizing Patient Psychosocial and Emotional Needs, Instilling Hope and Encouragement in Patients, and Creating a Comforting Environment to Foster Sharing of felt needs. Discussion Nurses emphasized the need of deeper inquiry into patients illness situation and complexity to discern the impact of determinants on their well-being and develop care plans that are tailored to address psychosocial, emotional, and physical suffering of this patient population. Conclusions Alleviation of patient suffering is integral to compassionate nursing care. Nurses use a multifaceted approach entailing sensitive understanding, recognizing sociocultural and structural determinants impact on patient situation, and individual and interdisciplinary altruistic actions to alleviate patient suffering.

We suggest that variation, error, and bias will be essential to include in a complete computational theory of groups – particularly given that formation of group representations must often rely on inferences of intentions. We draw on the case study of paranoia to illustrate that intentions that do not correspond to group-constitutive roles may often be perceived as such.

The proliferation of AI systems across all domains of life as well as the complexification and opacity of algorithmic techniques, epitomised by the bourgeoning field of Deep Learning (DL), call for new methods in the Humanities for reflecting on the techno-human relation in a way that places the technical operation at its core. Grounded on the work of the philosopher of technology Gilbert Simondon, this paper puts forward individuation theory as a valuable approach to reflect on contemporary information technologies, offering (...) an analysis of the functioning of deep neural networks (DNNs), a type of data-driven computational models at the core of major breakthroughs in AI. The purpose of this article is threefold: (1) to demonstrate how a joint reading of Simondon’s mechanology and individuation theory, foregrounded in the Simondonian concept of information, can cast new light on contemporary algorithmic techniques by considering their situated emergence as opposed to technical lineage; (2) to suspend a predictive framing of AI systems, particularly DL techniques, so as to probe into their technical operation, accounting for the data-driven individuation of these models and the integration of potentials as functionality; and finally, (3) to argue that individuation theory might in fact de-individuate AI, in the sense of disassembling the already-there, the constituted, paving the way for questioning the potentialities for data and their algorithmic relationality to articulate the unfolding of everyday life.

This paper addresses the issue of how to best account for the diversity of our (synchronic) mental activities. The discussion starts with Mark Textor’s mental monism. According to mental monism, our mental life is constituted by just one simple mental act, in which different sub-acts can be conceptually distinguished. Textor grounds this view in the work of the early Brentano and contrasts it with the theory of the later Brentano, who introduces a mental substance into his philosophy. According to Textor, (...) Brentano needs a substance because he is unable to explain how mental monism can account for the separability of our mental activities, e.g. the fact that I can stop hearing F while still seeing blue. Textor argues, however, that mental monism can solve this problem. I address two issues regarding Textor’s view. First, I challenge his interpretation of Brentano by arguing that the early Brentano imports ontological complexity into our mental life; I defend Brentano’s view against possible criticisms, and I address some objections to mental monism. Second, I oppose Textor’s narrative about the mental substance. I argue that Brentano needs a substance not to explain separability, but rather to individuate our mental acts. I still argue, however, that Brentano’s earlier view (understood in my sense) is better than the substance account for dividing the mind. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 22 (2002) 115-121 [Access article in PDF] Instrumentality, Complexity, and Reason: A Christian Approach to Religions Terry C. Muck Asbury Theological Seminary I want to call into question The Paradigm, the threefold classification of Christian approaches to other religions as Exclusivism, Inclusivism, and Pluralism. I call this classification The Paradigm, with a capital T and a capital P, because it is the way we have categorized Christian (...) theological approaches to the other religions ever since 1982, when Alan Race proposed this "broad typological framework within which most of the current Christian theologies of religions can be placed," in his book Christians and Religious Pluralism: Patterns in the Christian Theology of Religions (Orbis Books). 1Race's was not the first attempt at such a paradigm. He was preceded by others, most notably Owen Thomas, who classified Christian responses to other religions under the headings of rationalism, romanticism, relativism, exclusivism, dialectic, reconception, tolerance, dialogue, catholicism, and presence. 2 But Thomas's categories have not stuck like Race's, perhaps because of the larger number and perhaps because they seem a mixture of apples and oranges, that is, a conglomeration of logical positions, emotive states, and simple demographics. Although this hodgepodge may be more true to the reality of the complex ways Christians relate to people of other faiths, Race's paradigm, simple and straightforward, has won out in the descriptive derby.I think it is time to question whether Race's paradigm should continue to be the primary way we classify the many ways Christian theologians and other Christians relate to the world's other religious traditions. I will describe why I think The Paradigm is losing its usefulness, make a proposal for a new way of looking at the other religions, and list both the losses/dangers and benefits of thinking in a new way. The Problem with the Paradigm The first sign that The Paradigm is showing its age is that very few people seem to really fit in any one of the three categories. I suspect that few of us here would be willing to say unambiguously, "I am an exclusivist," or "I am an inclusivist," or "I am [End Page 115] a pluralist." 3 And even if we were willing to identify with one or another of the options, then most likely we would in the same breath quickly say something like, "But let me tell you what I mean when I say I am an exclusivist (or inclusivist or pluralist)." That is, we quickly define the words in qualifying ways that address the objections that have been raised in reference to each of the positions:Exclusivists, for example, struggle to counter the charges of being inhumane, 4 or of making God seem inhumane, 5 or of being narrow, or of being misinformed, 6 or of being unscholarly. 7Inclusivists, for their part, struggle to counter the charges of being Christian exclusivists in disguise, 8 or of being offensive to non-Christians, 9 or of being pluralists in disguise, 10 or of holding a philosophically unstable position.Pluralists, in turn, make sure we know they are not relativists, 11 that they are not necessarily universalists, 12 that being a pluralist does not mean they are a-religious or that they consider themselves above the fray of common religious commitment. 13I don't think that this problem has just to do with the fact that the paradigm is what Max Weber called an ideal-type paradigm, where we set up ideal types as a way of clearly delineating logically possible positions vis-à-vis a presenting issue as a heuristic device. 14 Were that the case, it seems to me that we could still embrace The Paradigm as a way of talking about interreligious interchange and explicitly/implicitly acknowledge to one another that we recognize the ambiguity of the categories when it comes to applying them to complex individual adherents of complex religious traditions. 15I think dissatisfaction with The Paradigm goes beyond frustration with it as an ideal-type typology. The Paradigm has come to stand for... (shrink)

Psychoanalytic Complexity is the application of a multidisciplinary, explanatory theory to clinical psychoanalysis and psychotherapy. It carries with it incisive and pivotal attitudes that aim to transform our understanding of therapeutic action and the change process. Here, William Coburn offers a revolutionary and far-reaching counterpoint to the remnants of Cartesianism and scientism, respecting and encouraging human anomaly rather than pathologizing or obliterating the uniqueness of the individual person. In Psychoanaltyic Complexity, William Coburn explores the value of complexity theory previously understood (...) as an explanatory framework with which clinicians can better understand, retrospectively, therapeutic action and the change process. He further extends this sensibility by examining the ways in which such a rich theoretical framework can inform what clinicians can do, prospectively, to effect positive change within the therapeutic relationship. He persuasively argues that the medium of bringing to light new ways of relating, emotional experiencing, and meaning making resides in the fundamental attitudes derived from a complexity theory sensibility as applied to psychoanalysis and psychotherapy. Using a variety of clinical illustrations throughout, Psychoanalytic Complexity is a radical corrective to reductionism and the more traditional presumption that the problem lies with the patient and the cure lies with the therapist. It offers a new language, vocabulary, way of thinking, and a new way of being with others that are pivotal in arriving at affirmative therapeutic change. This book is intended for psychoanalysts, clinical psychologists, therapists, mental health counsellors, academics and teachers who are interested in new trends in psychoanalysis and psychotherapy.

This book examines the different conceptions of the individual that have emerged in recent new approaches in economics, including behavioral economics, experimental economics, social preferences approaches, game theory, neuroeconomics, evolutionary and complexity economics, and the capability approach. These conceptions are classified according to whether they seek to revise the traditional atomist individual conception, put new emphasis on interaction and relations between individuals, account for individuals as evolving and self-organizing, and explain individuals in terms of capabilities. The method (...) of analysis uses two identity criteria for distinguishing and re-identifying individuals to determine whether these different individual conceptions successfully identify individuals. Successful individual conceptions account for sub-personal and supra-personal bounds on single individual explanations. The former concerns the fragmentation of individuals into multiple selves; the latter concerns the dissolution of individuals into the social. The book develops an understanding of bounded individuality, seen as central to the defense of human rights. (shrink)

Although the individuality of whole-body movements has been suspected for years, the scientific proof and systematic investigation that individuals possess unique movement patterns did not manifest until the introduction of the criteria of uniqueness and persistence from the field of forensic science. Applying the criteria of uniqueness and persistence to the individuality of motor learning processes requires complex strategies due to the problem of persistence in the learning processes. One approach is to examine the learning process of different (...) movements. For this purpose, it is necessary to differentiate between two components of movement patterns: the individual-specific component and the discipline-specific component. To this end, a kinematic analysis of the shot put, discus, and javelin throwing movements of seven high-performance decathletes during a qualification competition was conducted. In total, joint angle waveforms of 57 throws formed the basis for the recognition task of individual- and discipline-specific throwing patterns using a support vector machine. The results reveal that the kinematic throwing patterns of the three disciplines could be distinguished across athletes with a prediction accuracy of up to 100% (57 of 57 throws). However, athlete-specific throwing characteristics could also be identified across the three disciplines. Prediction accuracies of up to 52.6% indicated that up to 10 out of 19 throws of a discipline could be assigned to the correct athletes, based on only knowing these athletes from the kinematic throwing patterns in the other two disciplines. The results further suggest that individual throwing characteristics across disciplines are more pronounced in shot put and discus throwing than in javelin throwing. Applications for training and learning practice in sports and therapy are discussed. In summary, the chosen approach offers a broad field of application related to the search of individually optimal movement solutions in sports. (shrink)

What enables individually simple insects like ants to act with such precision and purpose as a group? How do trillions of individual neurons produce something as extraordinarily complex as consciousness? What is it that guides self-organizing structures like the immune system, the World Wide Web, the global economy, and the human genome? These are just a few of the fascinating and elusive questions that the science of complexity seeks to answer. In this remarkably accessible and companionable book, leading (...) class='Hi'>complex systems scientist Melanie Mitchell provides an intimate, detailed tour of the sciences of complexity, a broad set of efforts that seek to explain how large-scale complex, organized, and adaptive behavior can emerge from simple interactions among myriad individuals. Comprehending such systems requires a wholly new approach, one that goes beyond traditional scientific reductionism and that re-maps long-standing disciplinary boundaries. Based on her work at the Santa Fe Institute and drawing on its interdisciplinary strategies, Mitchell brings clarity to the workings of complexity across a broad range of biological, technological, and social phenomena, seeking out the general principles or laws that apply to all of them. She explores as well the relationship between complexity and evolution, artificial intelligence, computation, genetics, information processing, and many other fields. Richly illustrated and vividly written, Complexity : A Guided Tour offers a comprehensive and eminently comprehensible overview of the ideas underlying complex systems science, the current research at the forefront of this field, and the prospects for the field's contribution to solving some of the most important scientific questions of our time.

Individuals are a prominent part of the biological world. Although biologists and philosophers of biology draw freely on the concept of an individual in articulating both widely accepted and more controversial claims, there has been little explicit work devoted to the biological notion of an individual itself. How should we think about biological individuals? What are the roles that biological individuals play in processes such as natural selection (are genes and groups also units of selection?), speciation (are (...) species individuals?), and organismic development (do genomes code for organisms)? Much of our discussion here will focus on organisms as a central kind of biological individual, and that discussion will raise broader questions about the nature of the biological world, for example, about its complexity, its organization, and its relation to human thought.

This study aimed to explore stakeholders’ perspectives on the ethical considerations for returning individual pharmacogenomics research results to people living with HIV. A qualitative approach to investigation involved five focus group discussions with 30 Community representatives, 12 key informant interviews with researchers, and 12 in-depth interviews with research ethics committee members. In total, 54 stakeholders who were involved in pharmacogenomics research and HIV treatment and care contributed to the data collection between September 2021 and February 2022. The study explored five (...) prominent themes: (i) defining the nature of research results to return to participants; (ii) preparing research participants to receive their results; (iii) obtaining informed consent for the return of results; (iv) opinions on health personnel to return the results to participants; and (v) opinions on how research results should be communicated to participants. Respondents identified various strategies for the return of individual results with minimal ethical risks including the setting up of a diverse and independent committee to undertake a risk-benefit assessment based on local context; ongoing discussions about the possible kinds of results and their implications throughout the study; and employing genetic counsellors to communicate results to participants. The strategies identified in this study should be further studied and independently verified. (shrink)

The aim of this book is to show how supramolecular complexity of cell organization can dramatically alter the functions of individual macromolecules within a cell. The emergence of new functions which appear as a consequence of supramolecular complexity, is explained in terms of physical chemistry. The book is interdisciplinary, at the border between cell biochemistry, physics and physical chemistry. This interdisciplinarity does not result in the use of physical techniques but from the use of physical concepts to study biological problems. (...) In the domain of complexity studies, most works are purely theoretical or based on computer simulation. The present book is partly theoretical, partly experimental and theory is always based on experimental results. Moreover, the book encompasses in a unified manner the dynamic aspects of many different biological fields ranging from dynamics to pattern emergence in a young embryo. The volume puts emphasis on dynamic physical studies of biological events. It also develops, in a unified perspective, this new interdisciplinary approach of various important problems of cell biology and chemistry, ranging from enzyme dynamics to pattern formation during embryo development, thus paving the way to what may become a central issue of future biology.

Philosophers have studied mechanisms in many fields in biology. The focus has often been on molecular mechanisms in disciplines such as neuroscience, genetics and molecular biology, with some work on population-level mechanisms in ecology and evolution. We present a novel philosophical case study of individual-level mechanisms, mechanisms in ecology and evolution that concern the interactions between an individual and its environment. The mechanisms we analyze are called Niche Choice, Niche Conformance and Niche Construction (NC3) mechanisms. Based on a detailed analysis (...) of biologists’ research practices, we develop metaphysical claims about the components and organization of NC3 mechanisms, the phenomena they bring about and how these phenomena relate to individual differences, a major explanatory target in the field. We provide reasons for why processes of niche choice, conformance and construction are mechanisms and how they differ from molecular mechanisms underlying individual differences. Finally, we demonstrate that a general representation of NC3 mechanisms is highly abstract, with more specific types of NC3 mechanisms in particular study systems exhibiting more complex components organized in more complex ways. Our case study highlights some distinctive features of individual-level mechanisms in ecology and evolution, such as complex and heterogeneous organization and multiple phenomena. (shrink)

A wide range of ecological and evolutionary models predict variety in phenotype or behavior when a population is at equilibrium. This heterogeneity can be realized in different ways. For example, it can be realized through a complex population of individuals exhibiting different simple behaviors, or through a simple population of individuals exhibiting complex, varying behaviors. In some theoretical frameworks these different realizations are treated as equivalent, but natural selection distinguishes between these two alternatives in subtle ways. (...) By investigating an increasingly complex series of models, from a simple fluctuating selection model up to a finite population hawk/dove game, we explore the selective pressures which discriminate between pure strategists, mixed at the population level, and individual mixed strategists. Our analysis reveals some important limitations to the ESS framework often employed to investigate the evolution of complex behavior. (shrink)

The Individual and the Political Order examines major theoretical perspectives, both historical and contemporary, in major issues in social and political philosophy. It combines accessibility with appreciation of philosophical complexity and discusses applied issues, such as morality and war, as well as theoretical approaches to justice, rights, and democratic liberal thought.

Because of its unprecedented speed and scale, urbanization in China during the 1990s is one of the most representative fields in which to explore compressed modernity considering East Asian experiences. This article focuses on a collective litigation including 10,357 people suing the local government for the infringements on their property rights and citizenship during that period of urbanization. To make this massive movement possible under an authoritarian state, a new type of state-individual relationship was created, and a selection mechanism applied (...) to the traditional, subordinate state-individual relationship and the modern, egalitarian state-individual relationship was constructed by the activists. The grassroots development of a strategic use of the law is the key to understanding how this selection mechanism was created. Activists distinguished multiple facets of “law”—literal law, symbolic law and practical law–to conceptualize the new egalitarian relationship through self-empowerment, in order to set the necessary preconditions for protesting, by segmenting the traditional state and to mobilize the network of participation by drawing upon the socialist memory of the “movement to popularize legal knowledge”. The selection mechanism described in this article could be considered as the response from individuals to the state during a time of transformation and shows the implication of temporality in the push and pull between individual rights and government overall control connected to the new and old systems. Tensions exist in this selection mechanism, and a paradox lies in the fact that the struggle for this egalitarian relationship should be based on the precondition that the subordinate relationship be internalized. By analyzing this complex process, this article points to China’s special social-historical process as it heads into modernity in an incremental and continuous way within such a short and compressed period of time, and also tackles the theoretical discussion of individualization from an East Asian perspective.

ABSTRACT Shagrir and Sprevak explore the apparent necessity of representation for the individuation of digits in computational systems.1 1 I will first offer a response to Sprevak’s argument that does not mention Shagrir’s original formulation, which was more complex. I then extend my initial response to cover Shagrir’s argument, thus demonstrating that it is possible to individuate digits in non-representational computing mechanisms. I also consider the implications that the non-representational individuation of digits would have for the broader theory of (...) computing mechanisms. 1 The Received View: No Computation without Representation 2 Computing Mechanisms and Functional Individuation 3 Against Computational Externalism 4 Implications for the Mechanistic Account.

Increasingly in economics what had been considered to be unusual and unacceptable has come to be considered usual and acceptable, if not necessarily desirable. Whereas it had been widely believed that economic reality could be reasonably described by sets of pairs of linear supply and demand curves intersecting in single equilibrium points to which markets easily and automatically moved, now it is understood that many markets and situations do not behave so well. Economic reality is rife with nonlinearity, discontinuity, and (...) a variety of phenomena that are not so easily predicted or understood. At the same time the broad coherence of economic systems is more impressive than ever in the face of such phenomena. The order of the economy appears to emerge from the complex interactions that constitute the evolutionary process of the economy. These phenomena have come to be labeled as complexity in economics. Even what seems simple in economics generally arises from behavior not reflecting rational expectations; we live in a world that reflects the enormous variety and diversity of humanity in their knowledge, attitudes, and behaviors, interacting with each other in an enormous range of institutional frameworks. What emerges in the aggregate may have little to do with what happens at the individual level. But this aggregate cannot be simply described by some set of aggregate equations. It emerges out of the soup of the individual and particular with all its multiform interactions and peculiarities. (shrink)

Consciousness has been the bone of contention for philosophers throughout centuries. Indian philosophy largely adopted lived experience as the starting point for its explorations of consciousness. For this reason, from the very beginning, experience was an integral way of grasping consciousness, whose validity as a tool was considered self-evident. Thus, in Indian philosophy, the question was not to move from the brain to mind but to understand experience of an individual and how such an experience is determined through mental structures (...) (and secondarily, the preoccupation with the brain and its relation to the mind). In contrast, cognitive science (the study of mind and cognition through 1 interdisciplinary methods, with emphasis on computational methods) found its debates soaked in discussion which primarily involved the brain and mind. Experience was not considered a primary source of information and its validity had to be established to consider it a source of information of mind. With the rise of physicalism and realization that mental states are correlative to brain states, the body was virtually neglected from involvement in understanding the mind and the attempts to reduce mind to the brain were rampant. The inability to explain subjective experience of an individual through neuroscientific findings alone has urged philosophers to explore other ways of understanding the ontology of mind. Over the last few years, embodied cognition and enactive approach have brought back the body as a central participant in this debate, providing fertile grounds to explain the relation of brain, body and mind. This paper proposes that we understand the brain as a complex system from which the mind emerges. This emergence is marked by the development of novel property of self-consciousness in human beings. The mind is a process which is embedded throughout the body and thus, the body acts as an actualizing medium for the individual. Thus, the brain is a necessary condition for the mind to be while the mind is embedded throughout the body. The brain and mind are in reciprocal causal relationship with one another, as is the body and environment with one another. In this paper, embodied cognition is understood through principles of Merleau Ponty's idea of embodiment, than through Andy Clark and Francis Varela's alone. (shrink)

Yarkoni's argument risks skepticism about the very possibility of social science: If social phenomena are too causally complex, normal scientific methods could not possibly untangle them. We argue that the problem of causal complexity is best approached at the level of scientific communities and institutions, not the modeling practices of individual scientists.

Although natural philosophers have long been interested in individuality, it has been of interest to contemporary philosophers of biology because of its role in different aspects of evolutionary biology. These debates include whether species are individuals or classes, what counts as a unit of selection, and how transitions in individuality occur evolutionarily. Philosophical analyses are often conducted in terms of metaphysics (“what is an individual?”), rather than epistemology (“how can and do researchers conceptualize individuals so as to address (...) some of their scientific goals?”). We review several philosophical distinctions in order to shift attention from metaphysics to epistemology. Many controversies involve epistemological differences rather than metaphysical disagreement. This implies that a pluralist stance about individuality in biology is warranted and has metaphysical consequences because the pluralism emerges from the diversity of scientific interests that investigate the complexity of living phenomena.

We explore the relationship between analytic behavior of a computable real valued function and the computability-theoretic complexity of the individual values of its derivative almost-everywhere. Given a computable function f, the values of its derivative \\), where they are defined, are uniformly computable from \, the Turing jump of the input. It is known that when f is \, the values of \\) are actually computable from x. We construct a \ function f so that, almost everywhere, \\ge _T x'\). (...) Although the values \\) at each point x cannot uniformly compute the corresponding jumps \ of the inputs x almost everywhere for any \ function f, we produce an example of a \ function f such that \\ge _T \emptyset '\) uniformly on subsets of arbitrarily large measure, effectively. We also explore analogous questions for weaker smoothness conditions, such as for f differentiable everywhere, and f differentiable almost everywhere. (shrink)

Language processing changes with the knowledge and use of two languages. The advantage of being bilingual comes at the expense of increased processing demands and processing costs. I suggest considering bilingual complexity including these demands and costs. The proposed model claims effortless monolingual processing. By integrating individual and situational variability, the model would lose its idealistic touch, even for monolinguals.

The current study highlights individual differences in the joint articulation strategies used by novices practicing a hip-hop dance movement, the wave. Twelve young adults, all naive regarding hip-hop dance performance, practized the wave in 120 trials separated into four blocks with the order of internal or external attentional focus counterbalanced across subjects. Various kinematic analyses were analyzed to capture performance success while exploiting the observed individual differences in order to establish the reliability of the proposed performance indicators. An external focus (...) of attention marginally facilitated the smooth transfer of a wave motion across neighboring limb segments as characterized by a constant propagation speed combined with large wave amplitudes. Systematic correlations between the success indicators were found, exemplifying the various degrees of joint articulation that novices prove capable of during an initial practicing session to try and perform a novel complex motor task.
