Let G = V G, E G be a molecular graph, where V G and E G are the sets of vertices and edges. A topological index of a molecular graph is a numerical quantity which helps to predict the chemical/physical properties of the molecules. The Wiener, Wiener polarity, and the terminal Wiener indices are the distance-based topological indices. In this paper, we described a linear time algorithm that computes the Wiener index for acyclic graphs and extended this algorithm for (...) unicyclic graphs. The same algorithms are modified to compute the terminal Wiener index and the Wiener polarity index. All these algorithms compute the indices in time O n. (shrink)

Epithelial tissues serve as critical barriers in metazoan organisms, maintaining structural integrity and facilitating essential physiological functions. Epithelial cell polarity regulates mechanical properties, signaling, and transport, ensuring tissue organization and homeostasis. However, the barrier function is challenged by cell turnover during development and maintenance. To preserve tissue integrity while removing dying or unwanted cells, epithelial tissues employ cell extrusion. This process removes both dead and live cells from the epithelial layer, typically causing detached cells to undergo apoptosis. Transformed cells, however, (...) often resist apoptosis, leading to multilayered structures and early carcinogenesis. Malignant cells may invade neighboring tissues. Loss of cell polarity can lead to multilayer formation, cell extrusion, and invasion. Recent studies indicate that multilayer formation in epithelial cells with polarity loss involves a mixture of wild‐type and mutant cells, leading to apical or basal accumulation. The directionality of accumulation is regulated by mutations in polarity complex genes. This phenomenon, distinct from traditional apical or basal extrusion, exhibits similarities to the endophytic or exophytic growth observed in human tumors. This review explores the regulation and implications of these phenomena for tissue biology and disease pathology. (shrink)

With the development of sentiment analysis, studies have been gradually classified based on different researched candidates. Among them, aspect-based sentiment analysis plays an important role in subtle opinion mining for online reviews. It used to be treated as a group of pipeline tasks but has been proved to be analysed well in an end-to-end model recently. Due to less labelled resources, the need for cross-domain aspect-based sentiment analysis has started to get attention. However, challenges exist when seeking domain-invariant features and (...) keeping domain-dependent features to achieve domain adaptation within a fine-grained task. This paper utilizes the domain-dependent embeddings and designs the model CD-E2EABSA to achieve cross-domain aspect-based sentiment analysis in an end-to-end fashion. The proposed model utilizes the domain-dependent embeddings with a multitask learning strategy to capture both domain-invariant and domain-dependent knowledge. Various experiments are conducted and show the effectiveness of all components on two public datasets. Also, it is also proved that as a cross-domain model, CD-E2EABSA can perform better than most of the in-domain ABSA methods. (shrink)

This study had two aims: to test the effect and the effect size of specific problematic Internet use [online shopping, online pornography, social network site usage, and Internet gaming] on generalized problematic Internet use and to reveal the gender differences in GPIU and SPIU for students from the elementary school level to the university level. In total, 5,215 Chinese students from four types of schools provided self-report data on demographic variables, online shopping, online pornography, SNS usage, Internet gaming, and GPIU. (...) After calculations had been controlled for demographic variables, the results indicated that online shopping, online pornography, SNS usage, and Internet gaming positively predicted GPIU—and Internet gaming was the most critical predictor of GPIU—and that gender differences were revealed in Internet gaming and GPIU in all educational levels, except at senior high school where the gender differences in GPIU were not significant. Significant gender differences were found for online shopping and online pornography for all educational levels above elementary school. These results provided further understanding of the association between GPIU and SPIU and gender differences in PIU, which suggested that gender differences across different educational levels should be considered in interventions of PIU.

Since the Second World War, an increasing number of scholars have begun to focus on research related to trauma. This article attempts to demonstrate the long-standing history of studying trauma issues. Ankersmit’s theory of historical trauma innovatively approaches the topic from an aesthetic perspective, incorporating the concept of forgetting which has been overlooked by previous historians. This theory not only explains the origins of Western historical consciousness but also breaks through the previous simplistic linear attribution of trauma severity, providing a (...) new direction for the study of trauma theory.

The COVID-19 pandemic has had a profound psychological and behavioral impact on people around the world. Consumer purchase behaviors have thus changed greatly, and consumer services companies need to adjust their business models to adapt to this change. From the perspective of consumer psychology, this paper explores the impact of consumer purchase behavior changes over the course of the pandemic on the business model design of consumer services companies using a representative survey of 1,742 individuals. Our results show that changes (...) in consumer purchase behavior have a significant impact on the design of consumer services firms’ business models. Specifically, changes in consumers’ purchase object, motive, and timeframe are more likely to spark a novelty-centered business model design, whereas changes in purchase method tend to inspire an efficiency-centered one. Our findings provide a theoretical reference for consumer services companies in designing business models when faced with unexpected crises. (shrink)

With the prevalence of the Internet and new media channels, consumer reviews have become one of the main determinants of Consumers’ purchasing decisions. This paper uses the Latent Dirichlet Allocation (LDA) model to identify the key factors that are of major concern to consumers, including design factors, laptop setup factors, logistics factors, after-sales factors, and user experience factors. And, we classify these factors into product quality factors and supporting service factors for new products. We then explore the relationship between online (...) reviews and purchase decisions under these different factors, and also further explore the impact of interactions between online review metrics on purchase decisions. Our findings suggest that the impact of online reviews on consumer purchase decisions also varies considerably across different consumer focus factors. In addition, we find that the impact of the interaction between online review features is complex. In particular, consumers do not follow the positive guidance and make purchase decisions as we would expect when confronted with a large number of positive emotional polarity online reviews. Meanwhile, the interaction between negative emotional polarity and variance of online reviews had no significant effect on consumer purchase decisions. The variance of online reviews has a limited role in reducing consumer risk perceptions triggered by negative emotional polarity. Our study provides new evidence for the study of the impact of online reviews through text mining. (shrink)

Transcranial magnetic stimulation, as a relatively new type of treatment, is a safe and non-invasive method for pain therapy. Here, we used CiteSpace software to visually analyze 440 studies concerning transcranial magnetic stimulation in pain research from 2010 to 2021, indexed by Web of Science, to clarify the research hotspots in different periods and characterize the process of discovery in this field. The United States ranked first in this field. Lefaucheur JP, Fregni F, and Andrade ACD made great contributions to (...) this field of study. The most prolific institution was University of São Paulo. The four main hot keywords were neuropathic pain, motor cortex, connectivity, and non-invasive brain stimulation. There were three main points that were generally accepted: definite analgesic effect of high-frequency rTMS of M1 contralateral to pain side in neuropathic pain; there are inconclusive recommendations regarding rTMS of the dorsolateral prefrontal cortex in fibromyalgia and neuropathic pain; there is low-quality evidence that single doses of high-frequency rTMS of the motor cortex may have short-term effects on chronic pain. This bibliometric analysis indicated that prospective, multi-center, large-sample, randomized controlled trials are still needed to further verify the effectiveness of various transcranial magnetic stimulation parameters in pain research.

ObjectiveTwo subregions of the dorsolateral prefrontal cortex have been identified as effective repetitive transcranial magnetic stimulation targets for the “anxiosomatic” and “dysphoric” symptoms, respectively. We aimed to develop a convenient approach to locate these targets on the scalp.Materials and methodsIn a discovery experiment, the two personalized targets were precisely identified on 24 subjects using a neuronavigation system. Then, a localized approach was developed based on individual scalp landmarks. This “landmark-based approach” was replicated and validated in an independent cohort. Reliability of (...) the approach was tested by calculating the correlation of both the inter-rater and intra-rater results. Validity was tested by comparing the mean distance between the personalized and landmark-based targets to the TMS spatial resolution. We further conducted a total of 24 sham rTMS sessions to estimate the misplacement between the coil center and target during a 10-min stimulation without neuronavigation.ResultsThe parameters of the “landmark-based approach” in the discovery experiment were replicated well in an independent cohort. Using discovery parameters, we successfully identified the symptom-specific targets in the independent cohort. Specifically, the mean distance between the personalized and landmark-based targets on the cortex was not significantly larger than 5 mm. However, the personalized and landmark-based targets distance exceeded 5 mm in more than 50% of subjects. During the 10-min sham rTMS session, the average coil misplacement was significantly larger than 5 mm.ConclusionThe “landmark-based approach” can conveniently and reliably locate the two symptom-specific targets at group level. However, the accuracy was highly varied at individual level and further improvement is needed. (shrink)

A positive connection has been established between personality traits and suicidal ideation. However, the possible mediation of resilience within this association has never been thoroughly discussed. In this study, we aimed to investigate this topic by using population-based cross-sectional survey data of 4,489 Chinese children and adolescents. A self-administered questionnaire was used to collect information from the participants. Univariate and multivariate logistic regression models were adopted to measure the crude and adjusted associations between personality traits, SI, and resilience. Path analysis (...) was performed to evaluate the mediation of resilience in the association between personality traits and SI. For 4,489 study subjects, the mean age was 13.4 years, ethnic minorities accounted for 71.8%, and over a half were middle school students. The reported prevalence rates for 1-week, 1-year, and lifetime SI were 27.6%, 35.5%, and 56.7%, respectively. Girls reported a significantly higher prevalence of SI than boys. Path analysis results revealed a prominent mediation of resilience; moreover, for different dimensions of personality traits, the proportion of mediation by resilience varied. Our major findings suggest that resilience-based intervention measures could be considered in preventing personality traits related to suicidal risk among youngsters. For children and adolescents, the measuring of personality dimensions may also be helpful in targeting key subpopulations of intervention priority. (shrink)

BackgroundBoosting the individual learning passion of medical students is a novel approach to improve their academic performance. It facilitates the medical education reform, motivating both policymakers and educators to focus on the function of positive psychology in the career development of medical students. Therefore, this study aimed to assess the status of two types of learning passion; to clarify the relationship between self-esteem and two types of learning passion among Chinese medical students; to examine the mediating role of psychological capital (...) in the relationship between self-esteem and two types of learning passion, respectively; and to identify the moderating role of professional identity in the relationship between PsyCap and two types of learning passion, respectively.MethodsA cross-sectional online survey was conducted from April to June 2016 in China. A total of 1,218 valid questionnaires were collected from four medical schools.ResultsSelf-esteem significantly and positively influenced medical students’ PsyCap.ConclusionTwo types of learning passion of medical students are positively influenced by self-esteem and PsyCap. Medical students with high-level self-esteem should possess strong PsyCap, which augments their harmonious as well as obsessive learning passion. Moreover, the positive effect of medical students’ PsyCap on harmonious learning passion is more notable among those with a lower professional identity. Finally, this study argues that strengths-based interventions of self-esteem and PsyCap are a beneficial approach for future enhancing learning passion in the domain of medical education. (shrink)

Growth mindset refers to our core belief that our talents can be developed through practice, which may influence our thoughts and behaviors. Growth mindset has been studied in a variety of fields, including education, sports, and management. However, few studies have explored whether differences in individuals’ growth mindsets influence college students’ self-reported mental health. Using the Growth Mindset Scale, Adolescent Self-rating Life Events Checklist, and SCL-90 Scale, data was collected from 2,505 freshmen in a University in China. Findings revealed that (...) the students within the growth mindset group scored significantly lower on “mental health issues” and “stress due to life events” than the students in the fixed mindset group. Our findings suggest that individuals with a growth mindset are less prone to mental health problems than individuals with a fixed mindset. (shrink)

Chez P. Ricoeur se distingue de langue et de parôle en analysant de discours. Il souligne en quoi une meilleure étude des structures narrative est éclairante pour l'étude du régime d'historicité, à condition de ne pas confondre dans une indistinction ontologique les discours d'ordre historique et d'ordre fictionnel.Avec Temps et Récit, Ricoeur poursuit aussi sa confrontation avec l'oeuvre de Heidegger, dont la réflrxtion sur l'historialité a beaucoup compté pour lui. On peut déceler derrière la triologie de Ricoeur une forme de (...) réponse à Etre et Temps. Selon Ricoeur, il ne s'agit d'hypostasier ni le récit ni le temps, mais de montrer comment dans la triangulation récit-temps-action, c'est en fait cette dernière dimention qui occupe une position fondatrice, car c'est dans l'agir et le pâtir que se situe la structure première du temps, laquelle ne peut s'exprimer que sous la forme d'un récit. On peut ainsi mesurer, sur un thème commun aux deux périodes, le parcours réalisé avec Temps et Récit. A la notion traditionnelle de continuité en histoire il substitue la notion plus élaborée de mise en intrigue, commeopération configurante du rapport du récit au temps. L'autre continuité majeure qui accompagne son intérêt pour la question de l'historicité est son souci de tenir ensemble les deux versants de celle-ci, le versant de l'histoire racontée et celui de l'histoire à faire, donc l'articulation sur un agir. P. Ricoeur place donc le discours historique dans une tension qui lui est propre entre identité narrative et ambition de vérité. Il y a aussi la condition de l'événement historique devient tributaire de sa mise en intrigue. Elle est la médiation qui assure la matérialisation du sens de l'expérience humaine du temps "aux trois niveaux de sa préfiguration pratique, de sa configuration épistémique et de sa reconfiguration herméneutique." La mise en intrigue joue le rôle d'opérateur, de miseen relation d'événements hétérogènes. En réticent face aux risques de l'hyperbole, convaincu du caractère aporétique de toute quête directe, de toute tentative de remontée aux conditions qui donnent accès à une temporalité toujours déjà constituée, déjà‐là, et donc nécessairement imparfaite.

Dans les théories traditionnelles de la sociologie du développement, les recherches se concentrent sur deux axes. D’un côté, les théories de la modernisation, qui étudient l’évolution des pays développés, de l’autre, celles du développement, qui s’intéressent aux modèles latino-américains, africains et est-asiatiques. Ces deux axes traditionnels limitent fortement le champ de vision de la sociologie du développement. Nous montrerons que les processus de transition dans les pays socialistes tels que la Chine, l’ex-URSS ou l’Europe de l’Est soulèvent toute une série (...) de débats inédits. Comment analyser la voie de développement propre à des régions et des pays différents ? Comment examiner les relations entre l’État et la société au sein du processus de développement et de transition ? Comment aborder le problème des inégalités sociales au sein de ce processus ? Autant de nouvelles questions – et ce ne sont pas les seules – qui élargissent non seulement le champ de vision de la sociologie du développement, mais qui permettent aussi d’envisager une nouvelle théorie pour cette discipline. Il s’agit d’observer le processus pratique de transition sociale dans les pays de l’ancien bloc communiste. L’objectif ? Restructurer la sociologie du développement autour de trois piliers : les théories de la modernisation, du développement et de la transition.Among the traditional theories in the sociology of development, research generally focuses on two lines. On the one hand, the theories of modernization, which mainly study the evolution of developed countries, on the other hand, the theories of development, which are interested in the patterns spread out by Latin America, Africa and East Asia. Those two directions set serious restrictions on the sociology of development’s scope. We’ll show that the transition processes of socialist countries such as China, ex-USSR or Eastern Europe actually raise a whole series of new debates. How should we analyze the specific way of development of countries or areas that are different ? How examine the relations between State and society during the development and transition process ? How should we deal with the issue of social inequalities during this process ? These new interrogations – and many others – do broaden the sociology of development’s horizons, but also help us build up a new theory for the discipline. We must scrutinize the practical process of social transition in the countries which were part of the former communist bloc, and, in so doing, rebuild the sociology of development on three pillars : the theories of modernization, of development and of transition.

Lumbar Exoskeleton, as an important instance of wearable exoskeleton, has broad application prospects in logistics, construction, and other industries. Specifically, in the working scenarios that require long-term and repeated bending and rising movements, active lumbar exoskeleton can provide effective protection and flexible assistance to wear’s waist muscles and bones, which will significantly reduce the risk of lumbar muscle strain. How to improve the human-machine coupling and enhance the assistance performance are the main challenges for ALE’s development. Based on the biomechanical (...) analysis of the movement of lifting heavy objects from bottom up, this paper proposes a lightweight but powerful ALE, named as SIAT-WEXv2, which can output maximum assistive force of 28 N. Additionally, we use robust fuzzy adaptive algorithm to improve SIAT-WEXv2’s antidisturbance ability, so that it can provide continuous and supple assistance for wearer. Electromyography signals of the lumbar erector spinae from ten subjects in two experimental cases were collected to evaluate the effectiveness of our new ALE. The experimental results indicate that the reduction of iEMG signal at LES decreased monotonically from 60% ± 5.5% to 40.5% ± 6.5% as the weight of lifting load increased from 0 to 25 kg. (shrink)

In the broadest sense of the phrase, there is action at a distance whenever there is a spatial or temporal gap between a cause and its effect. In this sense, it is not at all controversial that there is action at a distance. To cite a few instances: the page a few inches in front of you is impinging on your senses; the Sun is now warming the Earth; we are still living with the consequences of the Second World War. (...) What is controversial is the idea of unmediated action at a distance, where there is both a gap between cause and effect and no intermediate causes and effects to fill it. The three examples just mentioned are cases of action at a distance, certainly, but not, surely, unmediated action at a distance. What we expect to find, in each case, is a spatially and temporally continuous causal series stretching across time and space. (shrink)

Increasing computational power and improving deep learning methods have made computer vision technologies pervasively common in urban environments. Their applications in policing, traffic management, and documenting public spaces are increasingly common (Ridgeway 2018, Coifman et al. 1998, Sun et al. 2020). Despite the often-discussed biases in the algorithms' training and unequally borne benefits (Khosla et al. 2012), almost all applications similarly reduce urban experiences to simplistic, reductive, and mechanistic measures. There is a lack of context, depth, and specificity in these (...) practices that enables semantic knowledge or analysis within urban contexts, especially within the context of using and occupying urban space. This paper will critique existing uses of artificial intelligence and computer vision in urban practices to propose a new framework for understanding people, action, and public space. This paper revisits Geertz's (1973) use of thick descriptions in generating interpretive theories of culture and activity and uses this lens to establish a framework to approach evaluating the varied uses of computer vision technologies that weigh meaning. By discussing cases of implemented examples of urban computer vision—from LinkNYC and Numina's urban measurements to the Detroit Police's use of DataWorks Plus's facial recognition technology—it proposes a framework for evaluating the thickness of the algorithm's conclusions against the computational method's complexity required to produce that outcome. Further, we discuss how the framework's positioning may differ (and conflict) between different users of the technology, from engineer to urban planner and policymaker, to citizen. This paper also discusses how the current use and training of deep learning algorithms and how this process limits semantic learning and proposes three potential methodologies toward gaining a more contextually specific, urban-semantic, description of urban space relevant to urbanists. This paper contributes to the critical conversations regarding the proliferation of artificial intelligence by challenging the current applications of these technologies in the urban environment by highlighting their failures within this context while also proposing an evolution of these algorithms that may ultimately make them sensitive and useful within this spatial and cultural milieu.

Unlike the physical sciences, sociology is frequently described as an interpretative non-experimental science. Comparative epistemology sheds new light on this claim. 1. Experimentation is not a constant character of the physical sciences; 2. Experimental hypothetical-deductive reasoning, including the test of predictions, is also practicable in sociology. The argument is developed by a detailed step-wise comparison of the prediction of light ray deviation within the Sun’s gravitational field made in 1919 (physics) and the prediction of 8% cosmopolitanism of Cambridge University between (...) 1250 and 1350 (sociology). Extensive analysis of regent masters’ prosopographic notes yields the result of 9.5 percent cosmopolitanism, which is close to the theoretical prediction. Au contraire des sciences physiques, la sociologie est souvent décrite comme une science interprétative et non-expérimentale. L’épistémologie apporte un éclairage nouveau sur cette position : 1) L’expérimentation n’est pas un trait constant des sciences physiques ; 2) Le raisonnement expérimental est également applicable en sociologie. L’argument est développé en comparant en détail le test de la prédiction d’une déviation des rayons lumineux dans un champ de gravitation effectué en 1919 et le test de la prédiction d’un taux de cosmopolitisme de 8 % de l’université de Cambridge dans la période 1250-1350.

The article presents musicological and existentialist philosophical discourses on renaissance and baroque structures in the works of two contemporary classical composers. The existentialist point of view is imposed due to the examination of contemporary music works in which historically conditioned practices are also found.

The two works D’Om Le Vrai Sens by Kaija Saariaho and Concerto Grosso “Sun Reflections” by Yordan Goshev are (...) stylistically very different but the first bears renaissance and the second – baroque features respectively. In consequence, Der Man or Das Man is defined by the opposition between renaissance humanism and the metaphysics of Being. (shrink)

This article aims to assess Anastasius of Sinai’s usage of ancient Chris-tian sources in the Hexaemeron. Close and thorough examination of his quotations from Justin Martyr, Ireneaus of Lyon, Methodius of Olympus and Eustathius of Antioch reveals that, apart from Methodius, the citations have no analogy to any of their works. On the contrary, the cited opinions appear either to have come from different authors, or to have been faked, in toto or in part, by Anastasius. The reason for (...) such a forgery lies in Anastasius’s attempt to rehabilitate the allegorical interpretation of Gen. 1-3, without being accused of Origenism. Anastasius’s witness to the ancient exegetical tradition is proven to be deliberately misleading, and therefore should not be taken at face value. (shrink)

A ready answer to the question of Empedocles’ thinking about Good and Evil is to be found in Aristotle, who provides us with this simple rule of thumb : Good is associated with Love, and Evil with Hate. Fundamentally obvious as that rule may be, we need to go beyond Aristotle’s words. This article investigates several topics : fire, the sun, water, the hoard of divine thought, reincarnation, Empedoclean ethics, and, finally, the Blessed Ones. Complexity rules our quest to determine (...) what belongs to the Good and what belongs to the Bad. There are times when Love takes advantage of Hate’s ability to cause separation. The sun, manifestation par excellence of fire, is loaded with ambivalence in Empedocles – even though the high value placed almost universally on light is a commonplace in Greek thought. Empedocles is torn between his sense of wonder at the works of Aphrodite and his pessimism on recognizing the infernal cycle in which mortals are involved. (shrink)

Among Plato’s dialogues, the Timaeus was the most authoritative for Middle Platonists. But alone it does not suffice to explain some of the most important tenets defended by these philosophers. A remarkable example is the doctrine of the three Principles, which characterizes imperial Platonism, and which cannot be stated on the basis of the Timaeus alone. In my paper I show that Numenius was influenced by the Republic as well : in the metaphor of the Sun he found the Good (...) as first principle and an indication of a second principle which is further subdivided into an Intellect thinking the Ideas and a Demiurge ordering the universe. This interpretation provides him with some interesting solutions. But such an influence also raises difficulties insofar as the causal role of the first principle is concerned. (shrink)

The essay illustrates the figure of Demetrios Kavàkis Rhaoul, Byzantine official at the service of the last two Paleologue emperors and of the Despots of the Peloponnese, who was also George Gemistos Plethon’s friend and student. Two short works of his are here published for the first time, one on the Sun God and another on the classification of the religions professed by humanity, alongside two small inedited letters by Plethon. In the first of the two writings, Kavàkis clears the (...) reasons for his aversion towards any kind of religion or philosophy that places the divine beyond the visible world and that believes in the existence of an intelligible or, even worse, over-intelligible world. These ideas lead him to clash not only with Christianity, but also with Plato and with the ideas of his beloved teacher Plethon, who, however, seems to agree with him in a dream. In the second writing this peculiar solar religion is reaffirmed, against the religion of poets and the religions of transcendence, warning however that nature wants some respect for the religion of ancestors, whichever this might be, when it is functional to the life of the society and of the State.

An outdated geography supplies the bond among the thirty‐one articles in Sur les traces des Cassini. In the seventeenth century, when the Italians Gian Domenico Cassini and his nephew Giacomo Filippo Maraldi were born in Perinaldo, north of Genoa, their birthplace belonged to the County of Nice. Hence the rationale of building a set of papers on astronomy in the south of France around Cassini I and his family, which for four generations ran the Royal Observatory in Paris.Over half the (...) articles concern the Cassinis, mostly Cassini I and his great‐great‐grandson and namesake Cassini IV. There was also a Cassini V, Henri de Cassini, who countered the family genius and stamina by preferring botany and dying early, of the same outbreak of cholera that took the life of Sadi Carnot, without having created Cassini VI. He had already entered the Academy of Sciences with a push from his father. “I dare to beg of you [Cassini IV wrote to his fellow academician A. M. Ampère] to consider whether this unique situation in the history of letters, [a family's] devotion to the sciences for five successive generations and 170 years, ought not add some weight to the scientific credentials of my son.” It is hard to refuse the children of important alumni.The portion of Traces dealing more directly with astronomy in the south of France gets off to a distant start. Pytheas of Marseilles, who lived about 350 b.c., sailed to the Orkneys and the Baltic and earned himself the reputation of a liar back home for his stories of midnight suns and frozen lakes. He measured the latitude of Marseilles, the obliquity of the ecliptic, and the size of the earth. Ptolemy praised him. Strabo did not: “Pytheas lied about everything and covered it up with his knowledge of astronomy and numbers.”No traces worth following up were laid down for just under two thousand years. Then, in 1580, Nicolas Fabri de Peiresc first saw the light of day. He lived in Italy for four years as a very young man, deepening his knowledge of astronomy and human nature and meeting the main future actors in the Galileo affair: Galileo himself, Bellarmine, and Matteo Barberini . At his center in Aix‐la‐Provence, Peiresc made many useful astronomical observations, some in collaboration with Pierre Gassendi. He died in harness, worrying about the change of the obliquity since the days of Pytheas.There follow articles on Provençal astronomers who determined longitude and latitude at sea, on neglected observers in Languedoc who assisted the cause of the Enlightenment, and on modern observatories in the south of France. The political circumstances after the defeat of 1870–1871 favored decentralization of astronomy away from the Paris Observatory. In Italy, too, recent political events—the unification of 1870—made a restructuring of astronomical institutions desirable and possible. But whereas France had too few observatories, Italy had too many. Georges Rayet and Pietro Tacchini, both astrophysicists, compared the circumstances in their countries and made mutually reinforcing proposals to their colleagues and governments. Their respective proposals, most of which were enacted, called for reassigning some Italian observatories to meteorological work, building new observatories in Besançon, Bordeaux, and Lyon, and refurbishing older ones at Marseilles and Toulouse. Once again, as in the days of Cassini I, Italy made a decisive contribution to the practice of astronomy in France.Sur les traces des Cassini mixes slight and weighty work, admits antiquarian and broader approaches, offers new documentation, displays pertinent illustrations, and does it all at a high level of scholarship. Since, because of its title, the book's primary audience probably will be people interested in the Cassinis, its fullest articles about them may usefully be mentioned here: Anna Cassini on Cassini's brief return to Italy, 1694–1696; Claude Teillet on the provincial life and poetry of Cassini IV; Christiane Demeulenaere‐Douyère on the Cassinis and the Académie des Sciences; Fabrizio Bonoli and Alessandro Braccesi on Cassini I's astronomical work in Bologna, with full bibliography; and Monique Pelletier on the Cassini map of France, on which she has written a book . Pytheas and Peiresc are the subjects of collaborative articles by Simone Arzano and Yvon Georgelin. (shrink)

In what is quite possibly the most famous passage of the De revolutionibus, Copernicus implies that nobody could ever place this supreme flaming torch that is the Sun in another or better place than that from which it can illuminate everything simultaneously, namely the centre of this extremely beautiful temple that is our world. Considering the fact that he leaves an interrogatory twist to this argument of convenience, and since he makes this statement without any justification as it seems entirely (...) evident to him, certain Copernicans choose to illustrate this by means of an analogy: if indeed the Sun must be positioned thus, it is because the most appropriate place for the torch intended to illuminate the room is at its centre, and not in one of its corners. Despite the heliosophy of the Renaissance having been shared by both geocentrists and Copernicans alike, this "torch" argument does not appear to have achieved much success: rarely adopted by the Copernican camp, it was even contested by some of them; as for the geocentrists, it held no appeal for them whatsoever. Did this argument of convenience therefore not benefit from the self-evidence attributed to it by Copernicus, and from, in his wake, it's continued support by a good many commentators? As is often the case when it comes to the history of thought, the pseudo-obviousness of this argument is merely the fruit of a blatant anachronism: presenting heliocentrism as the cosmological system that finally grants the Sun its worthy centrality by placing it in the centre of the room and not in a corner, is to ignore the fact that this star of the day already enjoyed, in geocentrism, a centrality esteemed to be perfectly in keeping with both its dignity and its inherent illuminative function. Having lost their grasp on this worldview that no longer belonged to them, the Copernicans thus put forward an argument which, for the geocentrists, is worthless. Yet they could have argued the objective superiority of their centrality over that accorded to the Sun by geocentrism: while the latter is only numerical, on a purely planetary scale, and frankly fictitious, the former is thoroughly spatial, of cosmic proportions and, at least on first approximation, very real. In order to produce arguments of convenience that could carry their own weight, the protagonists of the new cosmology would have benefited from getting to know the world vision of their adversaries a little better instead of addressing them from their own point of view; similarly, instead of treating as an obvious fact that which is only evident to one of the two parties present, historians of scientific thought would also be well advised to have a better understanding of the world vision of those who history now considers as the losers!

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Volcanus: Recherches comparatistes sur les origines du culte de VulcainJ. LinderskiGérard Capdeville. Volcanus: Recherches comparatistes sur les origines du culte de Vulcain. Rome: Ecole Française de Rome, Palais Farnèse, 1995. viii 1 521 pp. Cloth, no price stated. (Bibliothèque des Ecoles Françaises d’Athènes et de Rome, fasc. 288)In the last twenty years the French School has published every two years one book on Roman religion: monographs dealing with (...) Fortuna, Mercurius, Ops, Penates, Providentia Deorum, Fratres Arvales, l’Association Dionysiaque (cf. JRS 78 [1988] 207–8), the Bacchanalia, religious architecture (Aurea templa), La vie religieuse des matrones, Le délit religieux (cf. CP 79 [1984] 174–77). Now we have a book about Volcanus. First let us remark on what this book is not: it is not a study of the cult of Volcanus, an encyclopedia that would systematically list and discuss all the literary, iconographic, and epigraphical evidence in Rome, Italy, and the provinces. It would be very pleasing to have such a book; perhaps pedestrian, but useful. For information we still have to turn to Georg Wissowa, to his ageless Religion und Kultus der Römer (2d ed. Munich 1912, 229–32); also informative is W. Eisenhut, “Volcanus,” RE Suppl. 14 (1974) 948–62. A rather balanced account of the origines appears in G. Camassa, “Sull’origine [End Page 644] e le funzioni del culto di Volcanus a Roma,” RSI 96 (1984) 811–54. Capdeville’s book we have for speculations, a paradise for those eager to delve into murky origins, and those who are transposed by the dazzling and uncertain art of comparativistic pleading. If bibliography (fifty-one pages, 425–75) stands for learning, it is a learned monograph; it ranges from Rome through Etruria to Crete and Cyprus. Surprisingly we find no Hittites or Turks (the relevance of the latter the reader will see revealed at the end of this piece).The book opens with an evocation of Georges Dumézil. Where do his manes lead the author? They lead to the fish. The monograph “est né... d’une interrogation sur les pisciculi des Volcanalia” (1), a subject which intrigued Dumézil himself (REL 36 [1959] 121–30). At the feast of Volcanalia on 23 August (see the references in A. Degrassi, Fasti anni Numani et Iuliani (5 Inscr. It. XIII.2 [Rome 1963] 500–502), populus pro se in ignem animalia mittit (Varr. LL 6.20). On 7 June (cf. Degrassi 466) the Ludi Piscatorii were celebrated a praetore urbano pro piscatoribus Tiberinis, quorum quaestus non in macellum pervenit, sed fere in aream Volkani, quod id genus pisciculorum vivorum datur ei deo pro animis humanis (Festus 274–76 L); but at the Ludi Piscatorii the offering was not pro animis but rather pro quaestu piscantium (Festus 232 L); cf. J. Le Gall, Recherches sur le culte du Tibre (Paris 1953) 48–50; J. Linderski, Ktema 17 ([1992] 1996) 58. Agni, the Indian god of fire, hated water and fish; this explains the Roman ritual (so Dumézil). Most scholars tacitly assume that pisciculi vivi were offered also on the Volcanalia, but Varro speaks generally of animalia: if he wanted to say pisces he would have said so. Volcanus was a god of destructive fire (so Wissowa, Dumézil, and many other scholars); it makes sense that to propitiate him not only fish, a symbol of water, were burnt, but also other animals (perhaps as a substitute offering; cf., on that sort of sacrifices, G. Capdeville, MEFRA 83 [1971] 283–323). In the context of incendia arcenda an inscription of the Domitianic time (ILS 4914) records an offering on the Volcanalia of vitulus robeus and verres r(obeus). This calls to mind the sacrifice of the rutilae canes to protect the crops from the burning sun (Festus 358 L).Of all of this Capdeville, surprisingly, does not write at all: after their debut on page 1 the pisciculi and the Volcanalia feebly reappear at the very end of the book (420–23), only to be disregarded. Capdeville claims that Volcanus was not at all, and never, a god of “feu destructeur.” But Dumézil too... (shrink)
