The spatial dynamics of the optical emission from an array of 50 times 50 individual microcavity plasma devices is investigated. The array is operated in argon and argon-neon mixtures close to atmospheric pressure with an ac voltage. The optical emission is analysed with phase and space resolution. It has been found that the emission is not continuous over the entire ac period, but occurs once per half period. Each of the observed emission phases shows a self-pulsing of the discharge, (...) with several bursts of emission of fixed width and repetition rate. The number of emission bursts depends on applied voltage and frequency. Spatially resolved measurements prove that the emission bursts are formed by overlapping emission pulses from single discharge cavities. Intensity differences between positive and negative half-wave can be interpreted through spatially resolved measurements of single discharge cavities. (shrink)

O objetivo é propor uma reconstrução racional da concepção da ciência de Duhem, por meio do recurso da metodologia da teoria da ciência, como uma teoria normativa da dinâmica do conhecimento. Essa reconstrução ajuda a estabelecer que Duhem não pode ser classificado como um convencionalista/pragmatista, como sugere a interpretação-padrão, e, além disso, que Duhem almeja construir uma concepção que seja um termo médio entre a concepção metafísica clássica e a concepção do convencionalismo/pragmatismo. A estratégia metodológica para construir esse termo médio (...) é a proposta de um realismo estrutural e convergente. Duhem substitui o sujeito transcendental dos clássicos por uma teoria transcendental a ser alcançada por um processo dinâmico. Using the resources of the methodology of theory of science we propose a rational reconstruction of Duhem's conception of science, interpreting it as a normative theory of the dynamics of knowledge. Such a reconstruction helps to establish that Duhem cannot be classified as a conventionalist/pragmatist as proposed in the standard interpretation, and, furthermore, that Duhem proposes to construct a conception of science as a middle way between a classical metaphysical conception and a conventionalist/pragmatist conception. The methodological strategy for this middle way is the proposal of a structural and convergent realism. Duhem replaces the transcendental subject of the classics with a transcendental theory to be reached by a dynamic process. (shrink)

Conflicts between science and religion revolve about fundamental assumptions more often than they do facts or theories. The key postulates that have guided science since the Enlightenment appear to be wholly inadequate to describe properly the development of ecosystems. An emended set of tenets adequate to the ecological narrative also significantly ameliorates the adversarial nature of the dialogue between scientists and theists.

The paper gives an account of Rāmakaṇṭha’s (950–1000) contribution to the Buddhist–Brāhmaṇical debate about the existence or non-existence of a self, by demonstrating how he carves out middle ground between the two protagonists in that debate. First three points of divergence between the Brāhmaṇical (specifically Naiyāyika) and the Buddhist conceptions of subjectivity are identified. These take the form of Buddhist denials of, or re-explanations of (1) the self as the unitary essence of the individual, (2) the self as the (...) substance to which mental properties belong, (3) the self as the agent of both physical actions and cognitions. The difference of Rāmakaṇṭha’s position from both Nyāya and Buddhism is then elaborated. He posits a self, but not one that is an eternally unchanging substance, nor one that is anything other than consciousness. Hence his difference from Nyāya. He falls with Buddhism in holding that consciousness does not require anything other than itself to inhere in, but departs from Buddhism in holding that consciousness is not momentary but enduring. The guiding metaphor here is light, but light considered as a dynamic, qualitatively unchanging repetition of the action of illumination. (shrink)

A growing number of lay Buddhist practitioners have sought out alternative ways to incorporate Buddhist teachings in their daily practices and make positive changes in society by “doing good” for others. Sometimes recognized as part of “humanistic Buddhism,” this approach emphasizes general morality and focuses on people who need help as a way to fulfill Buddhist teachings in this world. Some Chinese Buddhist practitioners who follow the Tibetan Buddhist tradition also carry out similar humanistic engagements but use more subtle space-making (...) processes and often “brand” these as Buddhist practices. Drawing on the ethnographic observations of lay Buddhist practitioners in urban China, this article examines how urban practitioners promote (middle-class) morality and well-being lifestyles through what I call “atmospheric Buddhism.” Ultimately, the article argues that an alternative mode of Buddhist practice is emerging in Chinese urban environments in order to cope with politically constrained environments.

ABSTRACTFacial stimuli are widely used in behavioural and brain science research to investigate emotional facial processing. However, some studies have demonstrated that dynamic expressions elicit stronger emotional responses compared to static images. To address the need for more ecologically valid and powerful facial emotional stimuli, we created Dynamic FACES, a database of morphed videos from younger, middle-aged, and older adults displaying naturalistic emotional facial expressions. To assess adult age differences in emotion identification of dynamic stimuli and to provide normative (...) ratings for this modified set of stimuli, healthy adults categorised for each video the emotional expression displayed, rated the expression distinctiveness, estimated the age of the face model, and rated the naturalness of the expression. We found few age differences in emotion identification when using dynamic stimuli. On... (shrink)

This article critically discusses the state of STS, expressing feelings of discontent regarding four aspects: policy relevance, conceptual language, too much focus on complexity, theoretical styles. Middle range theory is proposed as an alternative, promising avenue. Middle range theories focus on delimited topics, make explicit efforts to combine concepts, and search for abstracted patterns and explanatory mechanisms. The article presents achievements in that direction for technology dynamics, particularly with regard to the role of expectations, niche theory and (...) radical innovation, and the multi-level perspective on sociotechnical transitions.

This essay will investigate the context – in terms of both sources (by means of influence, transformation, or contrast) and ancient reception – of the concept of the dynamic unity of the Father in the Son and the Son in the Father (John 10:38, 14:10, 17:21) in both ‘pagan’ and Christian Middle-Platonic and Neoplatonic thinkers. The Christians include Clement of Alexandria, Origen, and Gregory of Nyssa, but also Evagrius Ponticus and John Scottus Eriugena. The essay will outline, in ‘ (...) class='Hi'>Middle Platonism’, the hierarchical theology of a first and second God (and sometimes a third), and in Neoplatonism, Plotinus’ three hypostases arranged in hierarchical order, which will be contrasted with Origen’s and the Cappadocians’ three divine hypostases that are equal – like those of Augustine. Thus, for Origen not only is the Son in the Father, as in a ‘pagan’ Middle and Neoplatonic scheme, but also the Father is in the Son, in a perfect reciprocity of dynamic unity. Origen subscribes to this reciprocity because, as I argue, he is no real ‘subordinationist’, but the precursor of the Nicene and Constantinopolitan line (the Cappadocians, especially Nyssen, developed and emphasised the notion of equality, bringing the three Hypostases of the Trinity to the level of Plotinus’ One, but the premises were all in Origen’s theology and his concept of the coeternity of the three Hypostases and their common divinity: Nyssen, like Athanasius, even use Origen’s arguments in his own anti-Arian polemic, as we shall see). Origen even interpreted Philo’s theology, also close to so-called Middle Platonism, in a non-subordinationistic sense, attributing to the Hypostasis of Logos/Sophia the various dynameis, such as Logos and Sophia, that Philo used most probably in a non-hypostatic sense. I shall also demonstrate how Gregory of Nyssa, significantly following Origen, in his work Against Eunomius used John 14:10a to refute the philosophical argument of Eunomius, who had a profoundly subordinationistic view of Christ with respect to the Father. Gregory’s solution is that neither the Father nor the Son are in an absolute sense, but both are in a reciprocal relation or σχέσις, what I shall present as Gregory’s own version of the dynamic unity (in turn grounded in Origen). I shall also concentrate on the use that Gregory makes of John 17:21-23 to argue that the unity of the Father and the Son, and of all believers – and eventually all humans – in them, is substantiated by the Holy Spirit, who is seen as a bond of unity. I shall study how the notion of the Father in the Son and the Son in the Father relates to the parallel statements in John 14:10, that Christ is in the disciples (and all believers) and these are in Christ – what I will call an ‘expansive’ notion of dynamic unity – and John 17:21, that just as the Father is in the Son and the Son in the Father, so the disciples and all believers too should become ‘one’ in the Father and the Son. Here, as I shall argue, Middle and Neoplatonic henology comes to the fore as a possible background and interpretive lens at the same time. I shall show how Origen joined it to the unifying force of charity-love (agape), in turn a central theme in John, and how Evagrius, performing his exegesis of these verses, interpreted henosis. A coda will explore the corollary of the Divinity ‘all in all’, which is not only a central tenet of Origen’s theology, but also of that of Proclus. It will be pointed out how this concept relates to the issue of the dynamic unity within the divine. (shrink)

I show that standard dynamic approaches to the semantics of epistemic modals invalidate the classical laws of excluded middle and non-contradiction, as well as the law of epistemic non-contradiction. I argue that these facts pose a serious challenge.

Scientists often think of the world as a dynamical system, a stochastic process, or a generalization of such a system. Prominent examples of systems are the system of planets orbiting the sun or any other classical mechanical system, a hydrogen atom or any other quantum–mechanical system, and the earth’s atmosphere or any other statistical mechanical system. We introduce a general and unified framework for describing such systems and show how it can be used to examine some familiar philosophical questions, (...) including the following: how can we define nomological possibility, necessity, determinism, and indeterminism; what are symmetries and laws; what regularities must a system display to make scientific inference possible; how might principles of parsimony such as Occam’s Razor help when we make such inferences; what is the role of space and time in a system; and might they be emergent features? Our framework is intended to serve as a toolbox for the formal analysis of systems that is applicable in several areas of philosophy. (shrink)

This article examines the relationship between two phenomena and their respective concepts circulating in contemporary affect theory, i.e., ‘affective resonance’ and ‘affective atmosphere.’ Identifying the main aspects of the two concepts clarifies how the phenomena differ from each other, as well as how they may relate in a dynamic interplay. In light of a distinction between and a conjunction of the aspects of ‘affective relationality’ and ‘affective spatiality,’ the paper proposes a conceptualization of this dynamic interplay through the concept (...) of ‘affective attunement,’ in which resonance and atmosphere are held to converge. As part of this endeavor, the paper further investigates the diverging philosophical traditions to which the two concepts of affective resonance and affective atmosphere originally belong, respectively Spinozist affect theory and New phenomenology.

This work presents a post-positivist research framework for explaining any surprising or anomalous fact in the evolutionary path of a complex, dynamic, and contingent social process. Firstly, it elaborates on the reconciliation betweenthe ontological and epistemological assumptions of Critical Realism with the principles of American Pragmatism. Next, the research method is presented: theoretical propositions about a social structure are translated into a set of grammar rules that acknowledge patterns of sequences of events, either involving individual action or interaction between actors (...) within a real social system. The result is a discrete mathematical model for a concrete category of social process based on these rules. Finally, data-grounded refinement of the theory is possible through comparison between cases belonging to the same category, but differing in some contingent pattern of sequences of event outcomes. Consequently, their grammars differ in some pairs of context-sensitive rules that explain this surprising fact, and the derivation of this alternative historical trajectory of event outcomes becomes an extension to the early category of social process. In this sense, the proposed framework suggests a hierarchy of classes of grammars for middle-range explanations based on the ontological assumption of the generative nature of social reality.

This study bases itself in the epistemological and methodological development of a broad and interdisciplinary dialogue where various voices in the form of different domains converse in order to establish an integrated whole. The research contributes to the actual corporative question regarding spirituality in the workplace, specifically aimed at the individual in the middle-career phase. This phase is characterised as a re-evaluation period aimed at personal and professional growth. A shift in emphasis to the meaning and sense of work (...) is linked to spiritual intelligence as spirituality can be described and understood as a type of intelligence. The study shows that the middle-career experience provides opportunity for an altered future view. Lifestyle coaching serves as facilitating process and offers guidance in answering existential questions which are included in the spiritual. The probable outcome promises to add meaning as a manifesting component in a dynamic and transforming life strategy. (shrink)

In the contemporary context of increasing inequality and various forms of segregation, this volume analyzes the transition to neoliberal politics in Santiago de Chile. Using an innovative methodological approach that combines georeferenced data and multi-stage cluster analysis, Méndez and Gayo study the old and new mechanisms of social reproduction among the upper middle class. In so doing, they not only capture the interconnections between macro- and microsocial dimensions such as urban dynamics, schooling demands, cultural repertoires and socio-spatial trajectories, (...) but also offer a detailed account of elite formation, intergenerational accumulation, and economic, cultural, and social inheritance dynamics.

A narrow conception of who counts among the marginalized can blind ethicists to the precarious position of groups who function as middle agents between elites and the lower class. The imposition of middle agency on such groups is a form of oppression that leaves them vulnerable to abandonment and attack. In Rwanda, discourses emanating from colonialism, classism, and racism obscured the Tutsi as middle agents, despite white Catholics' dedication to the poor. By neglecting to recognize middle (...) agency as a type of marginalization, missionaries contributed negatively to the genocide. Liberatory practices are recommended so that ethicists can expose and challenge the dynamics of middle agency and include all the marginalized in liberation strategies. (shrink)

Evolutionary developmental biology (or developmental evolution) is in the middle stages of its “development.” Its early ontogeny cannot be traced back to fertilization but pivotal developmental events included Gould’s (1977) treatment of heterochrony, Riedl’s (1978) analysis of “burden”, the Dahlem conference of 1981, a British Society of Developmental Biologists Symposium, as well as books that incorporated developmental genetics into older comparative themes. A major inductive process began with the discovery of widespread phylogenetic conservation in homeobox-containing genes. One interpretation of (...) these early developmental dynamics holds that an increasingly prominent problem agenda (e.g., how do novel structures and functions originate?), inherited from long-standing research programs in comparative embryology, morphology, and paleontology, was handed a powerful set of experimental tools from the lineage of experimental embryology. This allowed for an experimental probing of development and its evolution in an unprecedented fashion. Although the relationship between evolution and development has exhibited a protracted and complex history, we are still in the process of comprehending these early stages of “modern” EvoDevo’s ontogeny.

The expansion and transformation of Asian economies is producing class structures, roles and identities that could not easily be predicted from other times and places. The industrialisation of the countryside, in particular, generates new, rural middle classes which straddle the worlds of agriculture and industry in complex ways. Their class position is improvised on the basis of numerous influences and opportunities, and is in constant evolution. Enormous though its total population is, meanwhile, the rural middle class remains invisible (...) to most scholars and policymakers. Contested Capital is the first major work to shed light on an emerging transnational class comprised of many hundreds of millions of people. In India, the 'middle class' has become one of the key categories of economic analysis and developmental forecasting. The discussion suffers from one major oversight: it assumes that the middle class resides uniquely in the cities. As this book demonstrates, however, more than a third of India's middle class is rural, and 17 per cent of rural households belong to the middle class. The book brings this vast and dynamic population into view, so confronting some of the most crucial neglected questions of the contemporary global economy. (shrink)

Migraine is a chronic and idiopathic disorder leading to cognitive and affective problems. However, the neural basis of migraine without aura is still unclear. In this study, dynamic amplitude of low-frequency fluctuations analyses were performed in 21 patients with migraine without aura and 21 gender- and age-matched healthy controls to identify the voxel-level abnormal functional dynamics. Significantly decreased dALFF in the bilateral anterior insula, bilateral lateral orbitofrontal cortex, bilateral medial prefrontal cortex, bilateral anterior cingulate cortex, and left middle (...) frontal cortex were found in patients with migraine without aura. The dALFF values in the anterior cingulate cortex were negatively correlated with pain intensity, i.e., visual analog scale. Finally, support vector machine was used to classify patients with migraine without aura from healthy controls and achieved an accuracy of 83.33%, sensitivity of 90.48%, and specificity of 76.19%. Our findings provide the evidence that migraine influences the brain functional activity dynamics and reveal the neural basis for migraine, which could facilitate understanding the neuropathology of migraine and future treatment.

Neurovascular coupling (NVC), the transient regional hyperemia following the evoked neuronal responses, is the basis of blood oxygenation level-dependent techniques and is generally adopted across physiological conditions, including the intrinsic resting state. However, the possibility of neurovascular dissociations across physiological alterations is indicated in the literature. To examine the NVC stability across sleep–wake states, we used electroencephalography (EEG) as the index of neural activity and functional magnetic resonance imaging (fMRI) as the measure of cerebrovascular response. Eight healthy adults were recruited (...) for simultaneous EEG-fMRI recordings in nocturnal sleep. We compared the cross-modality (EEG vs. fMRI) consistency of functional indices (spectral amplitude and functional connectivity) among five states of wakefulness and sleep (state effect). We also segregated the brain into three main partitions (anterior, middle and posterior) for spatial assessments (regional effect). Significant state effects were found on δ, α and fMRI indices and regional effects on the α and fMRI indices. However, the cross-state EEG changes in spectral amplitude and functional connectivity did not consistently match the changes in the fMRI indices across sleep–wake states. In spectral amplitude, the δ band peaked at the N3 stage for all brain regions, while the fMRI fluctuation amplitude peaked at the N2 stage in the central and posterior regions. In regional connectivity, the inter-hemispheric connectivity of the δ band peaked at the N3 stage for all regions, but the bilateral fMRI connectivity showed the state changes in the anterior and central regions. The cross-modality inconsistencies across sleep–wake states provided preliminary evidence that the neurovascular relationship may not change in a linear consistency during NREM sleep. Thus, caution shall be exercised when applying the NVC presumption to investigating sleep/wake transitions, even among healthy young adults. (shrink)

As a result of the increasing economical exploitation of outer space, humanity faces a new challenge that, as well as having economic advantages, also entails a great many ecological hazards. At present, the human race is encroaching on outer space, particularly in the form of almost 5000 active satellites and the corresponding space debris they produce. For the large part, this debris burns up on entering the Earth’s atmosphere, yet time and again it still does cause damage. However, this (...) could change dramatically if, as is now foreseeable, further uses of outer space, such as tourism, so-called satellite mega-constellations, regular transport flights to the moon or even Mars and the extraction of water and valuable rocks from celestial bodies, are expanded. There is a danger that ecological damage like that of the earlier phases of economic development will become externalised and ultimately pose a threat to the whole of humanity. Sautter’s ‘global “sustainability trilemma”’ remains unresolved. This trilemma consists in the fact that, in political resolutions, ‘the growth of resource-intensive prosperity is weighted far more highly than the conservation of functioning ecosystems and the implementation of inter- and intragenerational “justice”’ and that there are ‘up until now no efficient and ethically acceptable solutions’ for this problem. In this situation, it is therefore more important that rules for the sustainable use of outer space be established and enshrined as legally binding so that it becomes possible to minimise or even to preclude negative ecological consequences.Contribution: Although the commercial use of outer space does not seem to be a crucial point, it marks a new step of the dynamics of modern economics that has to be identified as an important ethical challenge. The article discusses aspects of ethics, law, religion and economy in a multidisciplinary way. (shrink)

This retrospective-descriptive study investigated how primary and middle-school children perceived the first COVID-19 lockdown in Italy as manifested in their drawings. Once school restarted after the first COVID-19 wave, and as part of a structured school re-entry program run in their class in September 2020, 900 Italian children aged 7–13 were asked to draw a moment of their life during the lockdown. The drawings were coded and quantitatively and qualitatively analyzed; several pictorial examples are illustrated in this article. Most (...) children used colorful and full-body representations of the self, but in almost half of the pictures drawn by older students, the self was either missing or represented without the face visible. Most children drew the interior of their houses, and the outside world was completely invisible in over half of the pictures. The most represented activities among younger students were playing or sport, followed by screentime or technology-use. Domestic routines and distance learning were also depicted. Most children, but predominantly girls, drew characters showing emotional cohesion clues, and more younger pupils and girls depicted contentment as their main emotion. Conflicting emotions were virtually non-existent. Our data suggest that children coped with the lockdown through play, screen, and technology use. The high incidence of the missing self-representation in preadolescents could indicate how the enforced loneliness and lack of direct physical contact with others impacted their perception of the self. The findings presented here deepen our knowledge of the dynamics connected to the effects of the COVID crisis on children and young people and show how drawings can provide a valuable window into children’s emotions and perceptions.

In lieu of an abstract, here is a brief excerpt of the content:Dynamic Encounters between Buddhism and the West ReportLaura Langone and Alexandra S. IlievaThe following is a summary of the 2021 Postgraduate Conference titled "Dynamic Encounters between Buddhism and the West," which took place online on June 28 and 29. The conference was conceptualized, organized, and run by three AHRC funded PhD students at the University of Cambridge: Laura Langone (Faculty of Modern and Medieval Languages); Alexandra S. Ilieva (Faculty (...) of Divinity); and Harry Harland (Faculty of Law). The conference took place over two days and featured eighteen presenters across six panels, and two keynote speakers. There were speakers from four continents (Europe, North America, Asia, and Oceania). A wide range of topics in multiple fields was discussed: religious studies, neuroscience, art history, politics, philosophy, literature, philology, mathematics, art, and music. Each day consisted of three panels, each with three presentations, one keynote presentation, and a networking session.The keynote speakers were Prof. Albrecht Classen (The University of Arizona) and Prof. Graham Parkes (University of Vienna).Prof. Classen opened the conference with his presentation. He taught us that we have been globalized and transcultural since at least the Middle Ages. To support this claim, he provided us with ample evidence of Buddhist-Western exchanges in Art and Literature dotted throughout the literature and architecture of Europe. Prof. Parkes observed that following Zen Master Dōgen's thought as well as Nietzsche's philosophy we can develop a saner approach to the environment, which provides us with resources to help us to tackle the challenges of the climate crisis.Our first panel was titled "Hellenistic-Buddhist Encounters," which followed on nicely from Prof. Classen's thesis that encounters between Buddhism and the West have been ubiquitous and have dated as far back as the Hellenistic period. Our second panel, "Encounters with the Contemporary World," were impressive examples of intercultural philosophy. Each participant demonstrated a unique ability to bring Buddhist ideas into dialogue with contemporary Western philosophy, specifically ethics, philosophy of mathematics, and epistemology. The third panel, titled "Therapeutic Encounters," taught us of the therapeutic value of Buddhist meditation and philosophical inquiry. As our presenters emphasized, this therapeutic value is not just an ancient artifact to be studied anthropologically, but a relevant and applicable approach to the modern idea of well-being that therefore deserves continued scholarship.On the second day, we started with our fourth panel called "Encounters through Western Conceptual Lenses," which among others gave us insight into the reception [End Page 393] of Japanese Buddhism by the German liberal protestants of the nineteenth century. Our fifth panel—"Encounters with German Philosophy"—was an excellent example of contemporary comparative work between Buddhist philosophy, ethics, and logic, and the German thinkers Hegel and Nietzsche.We learned that Nietzsche labeled Buddhism as nihilism––a position that can be challenged through Ambedkar's reading of Buddhism. On the other hand, despite Nietzsche's criticism of Buddhism, striking similarities between his approach to life and that of Mahāyāna Buddhism can be found, both elaborating a life-affirming philosophy. We also became familiar with similarities and differences between the logic of Nishida and Hegel. Finally, our last panel, "Literary and Artistic Encounters" made for a fitting conclusion, reminding us that Buddhist-Western encounters are ongoing, not just politically and intellectually but also in art, music, and literature. These encounters are dynamic in nature and fundamentally lacking in an essential core. Instead, they are entities that echo through the ages allowing for reinterpretation and reintegration across geographic and temporal scopes.Both during and after the conference we received extremely positive feedback from the participants. The level of participation and enthusiasm was highly promising, showing that the future of intercultural studies of this sort is bright. Graduate conferences like these are key for early career scholars to set up networks and find likeminded peers to engage in ongoing dynamic encounters.In conclusion, this conference served to highlight the sophisticated emerging scholarship taking place that seeks to investigate Buddhist-Western interactions and dialogue. But, perhaps more importantly, the conference itself makes a metapoint: not only has the world been transcultural for many centuries, but the conference itself and in particular the global spatial locations of...

Stocks and flows are building blocks of dynamic systems: Stocks change through inflows and outflows, such as our bank balance changing with withdrawals and deposits, or atmospheric CO2 with absorptions and emissions. However, people make systematic errors when trying to infer the behavior of dynamic systems, termed SF failure, whose cognitive explanations are yet unknown. We argue that SF failure appears when people focus on specific system elements, rather than on the system structure and gestalt. Using a standard SF task, (...) SF failure decreased by a global as opposed to local task format; individual global as opposed to local processing styles; and global as opposed to local perceptual priming. These results converge toward local processing as an explanation for SF failure. We discuss theoretical and practical implications on the connections between the scope of attention and understanding of dynamic systems. (shrink)

Atmospheric pollution is deteriorating, which has affected the evolution of respiratory disease for the exposed human worldwide. Thus, exploring the influence of air pollution on the evolution of disease transmission dynamics is a significant issue. In this article, a stochastic susceptible-infective epidemic model in a polluted atmospheric environment is investigated. The existence and uniqueness of the global positive solution are established. In virtue of the aggregation methods and Lyapunov function, the sufficient conditions of disease extinction, persistence, and existence of (...) the stationary distribution are established, respectively. TakingPM2.5concentration as the air pollutant index, numerical simulations are carried out to support these results. Our results indicated that the disease transmission dynamics are significantly associated with the environmental atmospheric pollution and fluctuation. (shrink)

Archaeology is a domain that studies material remains of past action in order to interpret past context and understand social structures and cultural dynamics. The archaeological record is the primary research object of archaeologists. It consists of static material traces of past events in the present and, by itself, it does not inform us about the past. The meaning of the archaeological record can be understood only by studying it, i.e. how the material remains were formed and what might (...) have been the past events that produced this kind of record.One of the problems archaeology faces is that archaeologists study past people, objects, and events, but as the past does not exist...

ObjectiveStatic regional homogeneity based on the resting-state functional magnetic resonance imaging has been used to study intrinsic brain activity in Alzheimer’s disease. However, few studies have examined dynamic ReHo in AD. In this study, we used rs-fMRI and dReHo to investigate the alterations in dynamic IBA in patients with AD to uncover dynamic imaging markers of AD.MethodIn total, 111 patients with AD, 29 patients with mild cognitive impairment, and 73 healthy controls were recruited for this study ultimately. After the rs-fMRI (...) scan, we calculated the dReHo values using the sliding window method. ANOVA and post hoc two-sample t-tests were used to detect the differences among the three groups. We used the mini-mental state examination and Montreal Cognitive Assessment to evaluate the cognitive function of the subjects. The associations between the MMSE score, MoCA score, and dReHo were assessed by the Pearson correlation analysis.ResultsSignificant dReHo variability in the right middle frontal gyrus and right posterior cingulate gyrus was detected in the three groups through ANOVA. In post hoc analysis, the AD group exhibited significantly greater dReHo variability in the right MFG than the MCI group. Compared with the HC group, the AD group exhibited significantly increased dReHo variability in the right PCG. Furthermore, dReHo variability in the right PCG was significantly negatively correlated with the MMSE and MoCA scores of patients with AD.ConclusionDisrupted dynamic IBA in the DMN might be an important characteristic of AD and could be a potential biomarker for the diagnosis or prognosis of AD.

Recently logic has shifted emphasis from static systems developed for purely theoretical reasons to dynamic systems designed for application to real world situations. The emphasis on the applied aspects of logic and reasoning means that logic has become a pragmatic tool, to be judged against the backdrop of a particular application. This shift in emphasis is, however, not new. A similar shift towards “interactive logic” occurred in the high Middle Ages. We provide a number of different examples of “interactive (...) logic” in the Middle Ages, all species of the disputation game obligatio. These games display a recognition of the importance of interaction in logical contexts and the way that interactive logic differs from single-agent inference. (shrink)

Globally, mortality and fertility rates generally fall as resource abundance increases. This pattern represents an evolutionary paradox insofar as resource-rich ecological contexts can support higher numbers of offspring, a component of biological fitness. This paradox has not been resolved, in part because the relationships between fertility, life history strategies, reproductive behavior, and socioeconomic conditions are complex and cultural-historically contingent. We aim to understand how we might make sense of this paradox in the specific context of late-twentieth-century, mid–demographic transition Chile. We (...) use distribution-specific generalized linear models to analyze associations between fertility-related life-history traits—number of offspring, ages at first and last reproduction, average interbirth interval, and average number of live births per reproductive span year—and socioeconomic position (SEP) using data from a cohort of 6,802 Chilean women born between 1961 and 1970. We show that Chilean women of higher SEP have shorter average interbirth intervals, more births per reproductive span year, later age at first reproduction, earlier ages at last reproduction, and, ultimately, fewer children than women of lower SEP. Chilean women of higher SEP consolidate childbearing over a relatively short time span in the middle of their reproductive careers, whereas women of lower SEP tend to reproduce over the entirety of their reproductive lifespans. These patterns may indicate that different SEP groups follow different pathways toward declining fertility during the demographic transition, reflecting different life-history trade-offs in the process.

The region of the Middle East is highly conflict-loaded. The absence of one distinct regional power may be considered both cause and consequence of this structural feature. At the same time, there are significant power gaps between states in the Middle East, with Israel among the most powerful actors and accordingly defined as a potential regional power. Due to the specific empirical setting of the Middle East region, an analytical design emphasizing relational and procedural dynamics is (...) required. In attempting to develop such a design, this paper utilizes three well-established schools of thought of international relations: (neo)realism, institutionalism, and constructivism. These three schools of thought are further used for developing hypotheses on both Israeli regional policy and its effects on the Middle East. After illustrating these hypotheses in relation to four periods in the contemporary history of Israel, theoretical lessons to be learned for the analysis of regional powers in other world areas are presented.

Abstract:Adaptive architecture has been investigated in its functional as well as technological capacities and potentials to respond to changing environmental conditions as well as user interactions – from kinetic façades to variable interiors. Yet, its dynamic aesthetics of various spatial, visual, and auditive states require further exploration, especially in relation to occupant perception and experience. We propose the phenomenological concept of atmospheres as a lens through which the aesthetics of adaptive architecture can be observed as fundamentally relational: as co-constituted by (...) “ambient qualities and human condition.” As these ambient qualities are getting more dynamic and are becoming increasingly manipulable with adaptive architecture, their critical reflection and negotiation is urgent; it has to involve occupants.

Creating a positive emotional atmosphere is essential for such communities’ healthy development as its boosts the continuous involvement of each member. However, the dynamic cross-influences and evolution of emotions in OBCs have not been fully explored, which was the research gap this paper tried to fill. Based on emotional contagion theory, this study identifies three sources (...) of textual sentiment through machine learning methods in OBCs: member’s posts, other members’ feedback, and the focal firm’s official feedback. This study further tested the dynamic emotional contagion process among these sources on valence and volatility, namely how they affected each other. Data was collected from the MIUI forum, a large forum launched by Xiaomi corporate on August 1, 2011, which contained 17,622 posts and 99,426 feedback. Results showed that: in the emotional contagion process, there existed differences in the influence of emotional valence and volatility from different sources; all emotional interactions were temporary and mostly lasted no more than three days; the most significant contributor of each sources’ emotion was itself, which could be explained by lagged effect; the valence of focal firm’s emotion was the second contributor of the valence of member’s emotion and other members’ emotion. Three sources of emotion in OBCs and emotional valence/volatility should be considered when firms try to guide the emotional changes in such communities. Furthermore, firms could proactively influence members’ emotions by carefully designing the feedback to members’ posts. Besides, since all interactions are temporary, firms need to engage in online communities frequently, like consistently offering feedback. (shrink)

Predation and escaping from predation through hiding are two fundamental phenomena in ecology. The most common approach to reducing the chance of predation is to use a refuge. Here, we consider a three species fishery model system with prey refuge induced by a Holling type-II functional response. These three species of fish populations are named prey, middle predator, and top predator. Harvesting is employed in most fishery models to achieve both ecological and commercial benefits. Research proves that non-linear harvesting (...) (Michaelis–Menten type) returns more realistic outcomes. So, we have combined the Michaelis–Menten type of harvesting efforts for all populations. Uniform boundedness conditions for the solutions of the model are discussed. The existence conditions for possible equilibrium points with stability are presented. We explain the dynamical behavior at each equilibrium point through bifurcation analysis. The persistent criteria of the system are examined. Bionomic equilibrium and optimal harvesting control using Pontryagin’s maximum principle are calculated. For validation of the model in the real world, we have implemented this in the freshwater ecosystem of Lake Victoria. Extraction of native fish species and ecological balances are the foremost solicitude of Lake Victoria. We may resolve this concern partially by implementing prey refuge, since it may sustain the ecology of Lake Victoria, and therefore also its economical importance. Lake Victoria is acclaimed worldwide for the trade of fishing. Also, it provides the largest employment in east-central Africa and is beneficial to fishing equipment manufacturers. So, the bionomic equilibrium and harvesting control have significant applications in the fisheries. All the analytical studies are verified by numerical simulations. We have plotted phase portraits, bifurcation diagrams, Lyapunov exponents to explore the dynamics of the proposed model. (shrink)

This book places thermodynamics on a system-theoretic foundation so as to harmonize it with classical mechanics. Using the highest standards of exposition and rigor, the authors develop a novel formulation of thermodynamics that can be viewed as a moderate-sized system theory as compared to statistical thermodynamics. This middle-ground theory involves deterministic large-scale dynamical system models that bridge the gap between classical and statistical thermodynamics. The authors' theory is motivated by the fact that a discipline as cardinal as thermodynamics--entrusted with (...) some of the most perplexing secrets of our universe--demands far more than physical mathematics as its underpinning. Even though many great physicists, such as Archimedes, Newton, and Lagrange, have humbled us with their mathematically seamless eurekas over the centuries, this book suggests that a great many physicists and engineers who have developed the theory of thermodynamics seem to have forgotten that mathematics, when used rigorously, is the irrefutable pathway to truth. This book uses system theoretic ideas to bring coherence, clarity, and precision to an extremely important and poorly understood classical area of science. (shrink)

This paper is an initial attempt to develop a dynamic conception of being which is not anarchic. It does this by returning to Aristotle in order to begin the process of reinterpreting the meaning of ousia, the concept according to which western ontology has been determined. Such a reinterpretation opens up the possibility of understanding the dynamic nature of ontological identity and the principles according to which this identity is established. The development of the notions of energeia, dynamis and entelecheia (...) in the middle books of Aristotle’s Metaphysics will be discussed in order to suggest that there is a dynamic ontological framework at work in Aristotle’s later writing. This framework lends insight into the dynamic structure of being itself, a structure which does justice as much to the concern for continuity through change as it does to the moment of difference. The name for this conception of identity which affirms both continuity and novelty is "legacy." This paper attempts to apprehend the meaning of being as legacy. (shrink)

Academic research suggests that variances in contextual dynamics, and more specifically religion, may lead to disparate perceptions and practices of corporate social responsibility. Driven by the increased geopolitical and economic importance of the Middle East and identified gaps in knowledge, the study aims to examine if indeed there is a divergent form of CSR exercised in the region. The study identifies unique CSR dimensions and constructs presented through an empirical framework in order to outline the practice and perception (...) of CSR in a context with strong Islamic beliefs. The framework goes beyond the platform of mere Islamic philanthropy and is based on CSR-stakeholder management practices. Following an exploratory research design and collecting interview data from representatives of 63 organisations from Saudi Arabia, the United Arab Emirates and Oman, the study offers a snapshot of the CSR reality from the perspective of those living the phenomenon. The results suggest that the practice and perception of CSR in the examined context are largely grounded in the areas of social and altruistic actions but they cannot be examined in isolation from the religious context of CSR operation. This focus is mainly attributed to the dominant role of Islam in the examined sample, which leads to forms of non-structured or semi-structured approaches to CSR. Apart from the theoretical advancements offered to the CSR literature, the study also provides contributions for practitioners and policy makers. (shrink)

The degree of autonomy present in the choices made by individuals with an addiction, notably in the context of research, is unclear and debated. Some have argued that addiction, as it is commonly understood, prevents people from having sufficient decision-making capacity or self-control to engage in choices involving substances to which they have an addiction. Others have criticized this position for being too radical and have counter-argued in favour of the full autonomy of people with an addiction. Aligning ourselves with (...) middle-ground positions between these two extremes, we flesh out an account of voluntary action that makes room for finer-grained analyses than the proposed all-or-nothing stances, which rely on a rather static metaphysical understanding of the nature of the voluntariness of action. In contrast, a dynamic concept of voluntary action better accounts for varying levels of voluntariness of the person with an addiction which takes into consideration internal and external determinants of choice. Accordingly, like other components of autonomous choices such as level of information, voluntariness can fluctuate. Therefore, there are important implications for research and clinical ethics in matters of consent, recruitment, and therapeutic approaches. Overall, our proposal is inspired by a pragmatist understanding of voluntary action, notably with respect to how voluntariness is both informed by actions and experiences that shape one's view of the world.

ABSTRACTIneffability of musical meaning is a frequent theme in music philosophy. However, talk about musical meaning persists and seems to be not only inherently enjoyable and socially acceptable, but also functionally useful. Relying on a phenomenological account of musical meaning combined with a naturalist explanatory attitude, we argue for a novel explanation of how ineffability is a feature of musical meaning and experience and we show why it cannot be remedied by perfecting language or musico-philosophical study.Musical meaning is seen as (...) an experiential phenomenon that consists of layers, some recent, others archaic. As such, musical meaning is strongly characterized by asubjectivity. It is in-between, in a state where the division of subject and object is not yet valid or valid anymore. A naturalistic interplay of experiential layers in music brings about a non-reified dynamics driving for expressions, interpretations, engenderings of subjects and objects or even for political action. Generally speaking, the in-betweenness of musical meaning can never be universally reified or symbolic nor can it ever be “subjective,” “mine” or present “at the origin.”In this view, ineffability has two primary reasons. First, the criteria offered for defining musical meaning are often too strict, resulting in untenable pretensions of universality. Second, the processual and relational nature of the in-between keeps meaning in flux; any snapshot creates a new situation and new meanings. (shrink)

Social information processing theory suggests that the chief executive officer’s entrepreneurial orientation is an organisational signal that influences the members’ innovativeness. Middle management teams are expected to be more innovative as they connect senior managers with frontline managers in the dynamic competitive environment of the digital economy. How CEOs guide MMT innovations through EO becomes critical in the process of capturing opportunities and creating value. However, previous research has failed to adequately identify distinct CEO EO manifestations with organisational contexts (...) configurations that influence MMTs innovation. Thus, based on differences in organisational contexts and MMTs’ cognition, this study thoroughly investigates how the vertical manifestation of CEO EO impacts the innovativeness of MMTs. We used fuzzy-set qualitative comparative analysis on a sample of 117 organisations to determine which configurations of CEO EO vertical penetration within an organisation can stimulate MMT innovativeness. The study discovered four first-level configurations that support stimulating MMT innovativeness respectively when the CEO EO is fully or partially manifested, and without the CEO EO. Moreover, we found the internal reasons for MMTs’ information interpretation heterogeneity, which is critical for realising the coordination and unity of entrepreneurial cognition and behaviours. Finally, these findings’ theoretical and practical implications are discussed. (shrink)

ABSTRACTThis paper explores specific forms that neoliberal discourse and culture in academia today take in the field of Israeli Middle Eastern and Islamic studies. The article applies various textual and contextual interrogation strategies to the language, narratives and the unsaid in interviews with leading scholars in the field, in order to construe what Fredric Jameson calls the ‘political unconscious,’ particularly that arising from the use of market as a conceptual metaphor. Contextualising this field of discourse within neoliberal academia, I (...) deconstruct the work ‘demand’ and ‘interest’ do, and highlight the dialectical dynamics of experts’ dependence on audience. I argue that, in this field, the economic discourse shelters Zionist logics, presuppositions and praxis, such as recruitment logics and fundraising practices that effectively address Jewish and Zionist students and donors.

BackgroundStreet-connected children and youth in low- and middle-income countries have multiple vulnerabilities in relation to participation in research. These require additional considerations that are responsive to their needs and the social, cultural, and economic context, while upholding core ethical principles of respect for persons, beneficence, and justice. The objective of this paper is to describe processes and outcomes of adapting ethical guidelines for SCCY’s specific vulnerabilities in LMIC.MethodsAs part of three interrelated research projects in western Kenya, we created procedures (...) to address SCCY’s vulnerabilities related to research participation within the local context. These consisted of identifying ethical considerations and solutions in relation to community engagement, equitable recruitment, informed consent, vulnerability to coercion, and responsibility to report.ResultsSubstantial community engagement provided input on SCCY’s participation in research, recruitment, and consent processes. We designed an assent process to support SCCY to make an informed decision regarding their participation in the research that respected their autonomy and their right to dissent, while safeguarding them in situations where their capacity to make an informed decision was diminished. To address issues related to coercion and access to care, we worked to reduce the unequal power dynamic through street outreach, and provided access to care regardless of research participation.ConclusionsAlthough a vulnerable population, the specific vulnerabilities of SCCY can to some extent be managed using innovative procedures. Engaging SCCY in ethical research is a matter of justice and will assist in reducing inequities and advancing their health and human dignity. (shrink)
