The paper studies the nature of understanding in condensed matter physics (CMP), mediated by the successful employment of its models. I first consider two obvious candidates for the criteria of model-based understanding, Van Fraassen's sense of empirical adequacy and Hacking's instrumental utility , and conclude that both are unsatisfactory. Inspired by Hasok Chang's recent proposal to reformulate realism as the pursuit of ontological plausibility in our system of knowledge, we may require the model under consideration to be understood (or intelligible) (...) before claiming model-based understanding. Here the understanding of a model typically consists of the following: figuring out at least one plausible (preferably realistic) physical mechanism for the model, determining the theoretical consequences of the model by mathematically probing it and developing our physical intuitions about the model. I consider the q-state Potts model to illustrate. After having understood a model, we may employ the model to understand its target phenomena in the world. This is done by matching one of the interpretative models of the model with the central features of the phenomena. The matching should be motivated (ideally both theoretically and empirically) in the sense that we have good reason to believe that the central features of the phenomena can be thought of as having more or less the same structure as postulated by the interpretative model. In conclusion, I propose a two-stage account of model-based understanding in CMP: (1) understanding of a model and (2) matching a target phenomenon with a well-motivated interpretative model of the model. Empirical success and instrumental utility both play their roles in the evaluation of how successful the model is, but are not the essential part of model-based understanding. (shrink)

Lawrence Sklar in his book, Physics and Chance (1993), proposes a sophisticated account of reduction of thermodynamics (TD) by statistical mechanics (SM). I argue that Sklar's analysis of the alleged reduction of TD by SM is problematic in several respects. I consider a few counterexamples to show that none of what Sklar takes to be the central features of successful reduction in science (unification and identification) holds in the case of TD and SM. I suggest the broader conclusion that a (...) more useful way of understanding the relationship between TD and SM is as collaboration and competition among alternative methodologies rather than reduction of one theory to another.

This paper aims: (1) to show that Lawrence Sklar`s recent attempt to reduce thermodynamics(TD) to statistical mechanics(SM) is fallacious in several respects; and (2) to suggest a broader conclusion that a more useful way of understanding the relationship between TD and SM is as collaboration and competition among alternative methodologies rather than reduction of one theory to another. To argue for (1), I discuss two cases (the distinction of intensive/extensive variables in TD and the existence of phase transitions) where TD (...) is more accurate than statistical mechnaics and thus corrects SM. I also discuss the case of temperature in order to argue for both (1) and (2). (shrink)

In this paper we give a full account of the work of William Thomson on absolute temperature, which to this day provides the theoretical underpinnings for the most rigorous measurements of temperature. When Thomson fashioned his concepts of ‘absolute’ temperature, his main concern was to make the definition of temperature independent of the properties of particular thermometric substances . He tried out a succession of definitions based on the thermodynamics of ideal heat engines; most notably, in 1854 he gave the (...) ratio of two temperatures as the ratio of quantities of heat taken in and given out at those temperatures in a Carnot cycle. But there were difficulties with using such definitions for experimental work, since it was not possible even to approximate an ideal Carnot engine in reality. More generally, it is not trivial to connect an abstract concept with concrete operations in order to make physical measurements possible. In the end, Thomson argued that an ideal gas thermometer would indicate his absolute temperature, and that the deviation of actual gas thermometers from the ideal could be estimated by means of the Joule‐Thomson effect. However, the measurement of the Joule‐Thomson effect itself required measurements of temperature, so there was a problem of circularity. (shrink)

The generation of isometric force at the hand can be mediated by activating a few motor modules. Stroke induces alterations in motor modules underlying steady-state isometric force generation in the human upper extremity. However, how the altered motor modules impact task performance remains unclear as stroke survivors develop and converge to the three-dimensional target force. Thus, we tested whether stroke-specific motor modules would be activated from the onset of force generation and also examined how alterations in motor modules would induce (...) changes in force representation. During 3D isometric force development, electromyographic signals were recorded from eight major elbow and shoulder muscles in the paretic arm of 10 chronic hemispheric stroke survivors and both arms of six age-matched control participants. A non-negative matrix factorization algorithm identified motor modules in four different time windows: three “exploratory” force ramping phases and the stable force match phase. Motor module similarity and between-force coupling were examined by calculating the scalar product and Pearson correlation across the phases. To investigate the association between the end-point force representation and the activation of the motor modules, principal component analysis and multivariate multiple linear regression analyses were applied. In addition, the force components regressed on the activation profiles of motor modules were utilized to model the feasible force direction. Both stroke and control groups developed exploratory isometric forces with a non-linear relationship between EMG and force. During the force matching, only the stroke group showed abnormal between-force coupling in medial-lateral and backward-forward and medial-lateral and downward-upward directions. In each group, the same motor modules, including the abnormal deltoid module in stroke survivors, were expressed from the beginning of force development instead of emerging during the force exploration. The PCA and the multivariate multiple linear regression analyses showed that alterations in motor modules were associated with abnormal between-force coupling and limited feasible force direction after stroke. Overall, these results suggest that alterations in intermuscular coordination contribute to the abnormal end-point force control under isometric conditions in the UE after stroke. (shrink)

Despite its importance, abnormal interactions between the proximal and distal upper extremity muscles of stroke survivors and their impact on functional task performance has not been well described, due in part to the complexity of upper extremity tasks. In this pilot study, we elucidated proximal–distal interactions and their functional impact on stroke survivors by quantitatively delineating how hand and arm movements affect each other across different phases of functional task performance, and how these interactions are influenced by stroke. Fourteen subjects, (...) including nine chronic stroke survivors and five neurologically-intact subjects participated in an experiment involving transport and release of cylindrical objects between locations requiring distinct proximal kinematics. Distal kinematics of stroke survivors, particularly hand opening, were significantly affected by the proximal kinematics, as the hand aperture decreased and the duration of hand opening increased at the locations that requires shoulder abduction and elbow extension. Cocontraction of the extrinsic hand muscles of stroke survivors significantly increased at these locations, where an increase in the intermuscular coherence between distal and proximal muscles was observed. Proximal kinematics of stroke survivors was also affected by the finger extension, but the cocontraction of their proximal muscles did not significantly increase, suggesting the changes in the proximal kinematics were made voluntarily. Our results showed significant proximal-to-distal interactions between finger extension and elbow extension/shoulder abduction of stroke survivors exist during their functional movements. Increased cocontraction of the hand muscles due to increased neural couplings between the distal and proximal muscles appears to be the underlying mechanism. (shrink)

Based on real-life intergroup animosities originating from a historical conflict, the current study examined how the perceived stance of the outgroup about the conflict affects the dehumanization of the outgroup. In Study 1, Korean undergraduates attributed more human nature to the Japanese after reading an article that the Japanese government did issue an official apology for a historical wrong. In turn, the more human nature assigned to the Japanese predicted higher expectations about positive mutual relations in the future. Similarly, in (...) Study 2, Japanese undergraduates attributed more human uniqueness to Koreans after reading an article that an official apology for a historical wrong from Japan was accepted by Koreans. The higher the perceived human uniqueness of Koreans was, the higher were the willingness to help and the expectations of a positive relationship in the future. The findings demonstrate how mutual dehumanization can be reduced as a result of the other side’s reconciliatory stances and can further contribute to improving intergroup relations. (shrink)

This article aims at an active dialogue between Ulrich Beck and East Asia with respect to cosmopolitan imagination. Beck’s cosmopolitan sociology requires a reflective cosmopolitan publicness to cope with various kinds of global risks. We therefore extract three different layers of publicness from neo-Confucianism – survival-oriented, deliberative, and ecological – and argue that Beck’s cosmopolitan vision can be better conceptualized when properly linked to, or founded upon, the Tianxiaweigong normative potentials of neo-Confucianism. In so doing our intention is to make (...) Beck’s implicit sensibilities and the implicit Asian orientations explicit, as a double process of cosmopolitan self-reflection and dialogue. We also draw attention to the analysis of the cosmopolitan actor in East Asia. Finally, we note that the cosmopolitan future of East Asia still remains uncertain and that reconciling global risk politics, national interests and cosmopolitan morality presents a big challenge to second modern transformation.

The Canadian-American biologist Edmund Vincent Cowdry played an important role in the birth and development of the science of aging, gerontology. In particular, he contributed to the growth of gerontology as a multidisciplinary scientific field in the United States during the 1930s and 1940s. With the support of the Josiah Macy, Jr. Foundation, he organized the first scientific conference on aging at Woods Hole, Massachusetts, where scientists from various fields gathered to discuss aging as a scientific research topic. He also (...) edited Problems of Ageing (1939), the first handbook on the current state of aging research, to which specialists from diverse disciplines contributed. The authors of this book eventually formed the Gerontological Society in 1945 as a multidisciplinary scientific organization, and some of its members, under Cowdry's leadership, formed the International Association of Gerontology in 1950. This article historically traces this development by focusing on Cowdry's ideas and activities. I argue that the social and economic turmoil during the Great Depression along with Cowdry's training and experience as a biologist – cytologist in particular – and as a textbook editor became an important basis of his efforts to construct gerontology in this direction.

Emmanuel Levinas’s doubts about the ethical value of artistic beauty have been widely acknowledged by the vast majority of Levinas’s commentators. However, though it is true that in “Reality and Its Shadow” Levinas persistently rebukes artistic beauty for its nonethicality, it is undeniable that he at least upholds the value of artistic criticism and modern literature. In this article I intend to relate Levinas’s exploration of the possibility of spiritual–ethical teaching in literature to Immanuel Kant’s reflections on the relation between (...) the feeling of beauty, that of sublimity, and sensible feeling in his third Critique. This up-close comparative examination fosters understanding of Levinas’s religious and philosophical approach to the sublime elements in some literary works, especially those of Fyodor Dostoevsky.

SUMMARYBy examining the use of tissue culture in post-war American biomedicine, this paper investigates how scientists experience and manage failure. I study how Leonard Hayflick forged his new definition of failure and ways of managing it by refuting Alexis Carrel's definition of failure alongside his theory of the immortality of cultured cells. Unlike Carrel, Hayflick claimed that every vertebrate somatic cell should eventually die, unless it transformed into a tumour cell. This claim defined cell death, which had been a problem (...) leading to a laboratory failure, as a normal phenomenon. On the other hand, permanent life, which had been considered a normal cellular characteristic, became a major factor causing scientific failure, since it implied malignant transformation that scientists hoped to control. Hayflick then asserted that his cell strains and method would partly enable scientists to manage this factor—especially that occurred through viral infection—alongside other causes of failure in routine tasks, including bacterial contamination. I argue that the growing biomedical enterprise fostered this work of Hayflick's, which had repercussions in both his career and the uses of cells in diverse investigations. His redefinition of failure in the age of biomedicine resulted in the broad dissemination of his cells, medium, and method as well as his long struggle with the National Institutes of Health, which caused his temporarily failed career.

This paper discusses how growth and aging became interrelated phenomena with the creation of gerontology in the United States. I first show that the relation of growth to senescence, which had hardly attracted scientific attention before the twentieth century, started to be investigated by several experimental scientists around the 1900s. Subsequently, research on the connection between the two phenomena entered a new domain through the birth of gerontology as a scientific field comprised of various disciplines, many of which addressed growth. (...) Due to gerontologists’ efforts, the association between aging and growth became stronger and more multifaceted within the discursive and organizational matrix constituting the new science, leading to a broader definition of senescence with an ambiguous connection to chronological age. Furthermore, as gerontologists borrowed the cultural agendas as well as research methods from studies of growth, aging began to be defined as a phenomenon that could be actively controlled and managed in both social arenas and laboratory environments.

This paper presents an analysis of the birth and growth of scientific creationism in South Korea by focusing on the lives of four major contributors. After creationism arrived in Korea in 1980 through the global campaign of leading American creationists, including Henry Morris and Duane Gish, it steadily grew in the country, reflecting its historical and social conditions, and especially its developmental state with its structured mode of managing science and appropriating religion. We argue that while South Korea’s creationism started (...) with the state-centered conservative Christianity under the government that also vigilantly managed scientists, it subsequently constituted some technical experts’ efforts to move away from the state and its religion and science through their negotiation of a new identity as Christian intellectuals. Our historical study will thus explain why South Korea became what Ronald Numbers has called “the creationist capital of the world.”. (shrink)

The Fourth Industrial Revolution has become a global buzz word since the World Economic Forum adopted it as an annual issue in 2016. It is represented by hyper automation and hyper connectivity based on artificial intelligence, big data, robotics, and Internet of things. AI, big data, and robotics can contribute to developing hyper automation that can increase productivity and intensify industrial production. Particularly, robots using AI can make decision by themselves as human being on complicated processes. Along with the hyper (...) automation, the hyper connectivity increases not only at national, but also global level by using information and communication technologies. IoT is the core technology to create the hyper connectivity in Cyber Physical System that connects technology, nature, and human being. Accordingly, a perfect convergence between ICT and manufacturing can be completed in the Fourth Industrial Revolution era and an extremely efficient flexible production system by spreading IoT in CPS will be established. Under such a condition, innovative clusters must play their traditional roles in cradles of technology innovation and commercialization. It must be difficult challenges for innovative clusters to meet their targets and to be adjusted by the changing new environment at the same time. This paper argues how the Fourth Industrial Revolution can change the global production chain and how core technologies function in industries. Furthermore, it focuses on how innovative clusters have to evolve to respond the Fourth Industrial Revolution. Last, but not least it also analyzes whether or not innovative clusters can play their roles as technology innovation hubs in the real world and CPS in the Fourth Industrial Revolution era. (shrink)

The purpose of this study was to identify relationship between leisure constraint negotiations and leisure activity participation through meta-analysis within the Korean context. Through this study, the inconsistent research results of previous studies are explained by comprehensively clarifying the relationship between the two variables and identifying a third variable that controls the relationship. The efforts of this project are expected to provide useful data that can be used for future research and to seek ways of increasing participation in leisure activities. (...) In order to achieve the purpose of this study, the research questions set in this study are as follows. First, what is the magnitude of the effect of the correlation coefficient between leisure constraint negotiations and leisure participation? Second, what are the variables that control the relationship between leisure constraint negotiations and leisure participation? Materials were collected by utilizing Research Information Sharing Service, DBpia, Korean studies Information Service System, and Korea Citation Index. Finally, 20 pieces of research materials were selected with a total of 6,843 participants. The conclusions drawn from the research questions set in this study are as follows. First, leisure constraint negotiations and leisure participation are in a static relationship, and their level is considerable. In other words, efforts to overcome leisure constraints increase participation in leisure activities. Second, gender, age, and type of active leisure activities are major variables that control the relationship between leisure constraint negotiations and leisure participation. Finally, the limitation of this study and future research orientation were discussed. (shrink)

In line with the new trend of the global economy, building innovative local clusters has become one of the core strategies to enhance economic development not only in the developed but also in the developing nations. Particularly the role and potential of localized innovation processes within clusters have been attracting considerable interests among scholars and policy makers alike. It is argued that the intensity and quality of competition is enhanced by the proximity of competitors in clusters. The paper argues how (...) to identify the tasks and strategies necessary in order to build locally embedded innovative clusters. (shrink)

Environmental, social, and governance is an indicator that measures a company’s non-financial performance. Many firms have recently emphasized the importance of ESG. Ascertaining what topics are being discussed around ESG and how they change over time will contribute significantly to gaining insight into ESG. Using 73,397,870 text data scraped and refined from publicly available Twitter data, this study applied Latent Dirichlet Allocation and the dynamic topic model to ascertain the hidden structure of the ESG-related document collection and the topics being (...) discussed. The study further conducts a sentiment analysis to examine the sentiment of the general public regarding ESG. Topic modeling shows that various topics regarding ESG are being discussed and evolve over time. Sentiment analysis shows that many people have neutral or positive sentiments toward ESG-related issues. This study contributes to exploring insights into ESG among the public and understanding public reactions toward ESG. We further conclude the study with a discussion of managerial implications and potential future research. (shrink)

In a knowledge-based economy, the role of regions is regarded as very significant for creating and dispersing knowledge. Particularly, geographical clusters of firms in a single sub-national region and cross-border regions may contribute to transmitting certain kinds of knowledge between and among firms. In addition, markets prefer to favor specialized firms with a coherent body of knowledge when knowledge creation and the use of new knowledge become increasingly important for maintaining and improving a firm’s competitiveness. This means that regional policy (...) makers may not interfere directly with markets and firms when the process of globalization pushes national economies into a world of learning and innovation because the institutional framework for market exchange favors knowledge exchange in a globalizing economic system. This paper argues how a cross-border cluster in the Öresund region between Denmark and Sweden has been created, and which strategies it focuses on in order to strengthen its competitiveness and to generate a further development that aims to become a global innovative cluster. Moreover, it discuses whether the Nordic cross-border cluster, the Medicon Valley is a unique approach in the EU context or not. Finally, it argues how it has created technology innovation as well as contributed to the regional economic growth. (shrink)
