This memoir consists of two parts, of which the first deals with the foundations of the theory of the struggle for existence, and begins with the introduction of the important concept of quantity of life, besides that of population. The fundamental equations are then established for the case where the individuals of a biological association mutually devour each other, the reasoning being based on the principle of encounters and on the fundamental hypothesis of the existence of equivalents of the individuals (...) constituting the different species which form the association.Having now obtained the equations which determine the rates of change of the numbers of individuals and of the quantities of life of the species, the memoir proceeds to find the equations relating to the stationary state, by establishing theorems which are afterwards applied for the purpose of obtaining the three general laws of the fluctuations. This investigation of the equilibrium state is then followed by the determination of the integrals of the fluctuation equations, and the deduction from these of their most important consequences.The second part of the memoir contains the enumeration and demonstration of the general laws of the struggle for existence, which flow from the discussion of the principles and the integrals obtained in the first part. In this way there is established a new sort of dynamics, demographic dynamics, which, though substantially different from the dynamics of material systems, is developed from an analogous point of view.The second part begins with the principle of the conservation of demographic energy, according to which there are two sorts of energy, one actual and one potential, which transform mutually the one into the other. This principle is the analogue of the principle of conservation of mechanical energy. It is followed by the enunciation of the three laws relating to the biological fluctuations, the experimental verification of which has been investigated by several naturalists. The success which has attended their efforts is well known.Everybody knows the importance ofHamilton's principle in mechanics and in all the domains of physical science. An analogous variation principle can be found in biology, and from it one can deduce the fluctuation equations in the canonical Hamiltonian form and also in the form of a Jacobian partial differential equation. Their integrals in involution from the subject next studied, and in this way are found cases where the integration is reducible to quadratures.Hamilton's principle leads to the principle of least action . There exists also in biology a closely related principle, which may be called the principle of least vital action. Its analytical form is such that it requires the existence of a true minimum, a state of affairs which does not always hold good in the analogous case in mechanics.Die Abhandlung besteht aus zwei Teilen: Der erste ist den Grundlagen der Theorie des Kampfes ums Dasein gewidmet. Man beginnt damit, neben der Bevölkerung die Menge des Lebens einzuführen, welche eine sehr wichtige Rolle spielt. Man geht dann dazu über, die Grundgleichungen für den Fall aufzustellen, in welchem die Individuen einer biologischen Assoziation sich gegenseitig auffressen. Man wendet das Prinzip der Begegnungen an und stützt sich auf die Grundhypothese der Existenz von Individuenäquivalenten der verschiedenen Arten, welche die Assoziation bilden.Wenn man die Gleichungen, welche die Variationen der Individuenzahlen und der Lebensmengen der Arten liefern, gefunden hat, so schreitet man zu den statischen oder Gleichgewichtsgleichungen fort und findet so die Theoreme, die man alsdann benutzt, um die drei allgemeinen Gesetze der Fluktuationen zu erhalten.Nach dem Studium des Gleichgewichtes geht man dazu über, die verschiedenen Integrale der Fluktuationengleichungen zu finden und zieht endlich aus ihnen die wichtigsten Folgerungen.Im zweiten Teile werden die allgemeinen Gesetze des Kampfes ums Dasein, welche aus der Diskussion der Prinzipien und der im ersten Teil gewonnenen Integrale stammen, ausgesprochen und bewiesen. Man baut so eine neue Dynamik auf: die demographische Dynamik, welche, obschon sie wesentlich verschieden von derjenigen der materiellen Systeme ist, sich nach einem analogen Gesichtspunkt entwickelt.Man beginnt in diesem zweiten Teil mit dem Prinzip der Erhaltung der demographischen Energie, nach welchem zwei Energien, die aktuelle und die potentielle, sich ineinander verwandeln. Wir haben hier eine Analogie zum Prinzip der Erhaltung der mechanischen Energie. Dann werden die drei Gesetze der biologischen Fluktuationen formuliert. Für sie haben verschiedene Naturforscher experimentelle Bestätigungen gesucht. Man kennt den Erfolg ihrer Bemühungen.Alle Welt kennt die Bedeutung des Prinzips vonHamilton in der Mechanik und in allen Gebieten der Physik. Man kann ein dem Variationskalkül analoges Prinzip in der Biologie finden. Aus ihm kann man die Fluktuationsgleichungen in der kanonischen Form vonHamilton und in der Gestalt einer Gleichung mit partiellen Differentialquotienten vonJacobi herleiten. Ihre Integrale bilden den Gegenstand der folgenden Studien. Man findet Fälle, in denen die Integration sich auf Quadraturen reduziert.Das Prinzip vonHamilton zieht das Prinzip der kleinsten Wirkung oder das Prinzip vonMaupertuis nach sich. Auch in der Biologie gibt es ein mit dem vorgenannten zusammenhängendes Prinzip, welches man das Prinzip der kleinsten vitalen Wirkung nennen kann. Seine analytische Form ist derart, dass es sich um ein wahres Minimum handelt, das im analogen Fall in der Mechanik nicht immer zutrifft. (shrink)

The aim of this article is to show that the trinitarian theology of Origen of Alexandria shares the same theoretical structure as the henology of Plotinus. In particular, there is a strong correspondence between the trinitarian hypostases in Origen and the moments of the One in Plotinus: the Father is the One; the Son-Logos is the Intelligence; finally, the Holy Spirit is the Soul. Both Origen and Plotinus seem to assume the ontological difference between God, who, on the one hand, (...) comes before the generation of the Son, i.e., before the distinction between Father and Son, and who is indeed God, and, on the other hand, God who is the Father as he generates the Son and who, by doing so, distinguishes himself from himself. The system of ideas which represents the basis of both the theology of Origen and the henology of Plotinus is evidently a Platonic one. (shrink)

Vito Tanzi offers a truly comprehensive treatment of the economic role of the state in the twentieth and twenty-first centuries from a historical and world perspective. The book addresses the fundamental question of what governments should do, or have attempted to do, in economic activities in past and recent periods. It also speculates on what they are likely or may be forced to do in future years. The investigation assembles a large set of statistical information that should prove useful (...) to policy-makers and scholars in the perennial discussion of government's optimal economic roles. It will become an essential reference work on the analytical borders between the market and the state, and on what a reasonable 'exit strategy' from the current fiscal crises should be. (shrink)

The development of the various themes of Catholic Social Teaching is based on numerous papal documents and ecclesiastical statements. While this paper provides a summary of a number of these documents, this paper focuses on two themes: the common good and care of the environment, and on three documents authored by Pope John Paul II in 1990, by Pope Benedict XVI in 2010, and by Pope Francis in 2015. By analyzing these documents from an engineer’s perspective, the author proposes a (...) model for Socially Responsible Engineering. The proposed model is intended to serve as a guide for engineering students and practicing engineers of all faith traditions and to those with no faith tradition at all who wish to incorporate CST in the daily conduct of their personal and professional lives; to provide guidance for the professional the author terms the aspiring Socially Responsible Engineer; and to offer engineers a preferred alternative to the undesirable aspects of the technocratic paradigm. While intended primarily for engineers, this document also serves as a guide for those with expertise in social justice and who, by gaining a better understanding of the thought processes of engineers, can become better mentors for engineering students and practicing engineers seeking to incorporate CST into their daily lives.

This volume presents a collection of essays on objectivity in legal discourse. Has law a distinctive type of objectivity? Is there one specific type of legal objectivity or many, depending on the observatory language utilized? Is objectivity fit for law? The analyses in the various contributions show that the Cartesian paradigm of objectivity is not relevant to the current legal discourse, and new forms of legal objectivity are revealed instead. Each essay, in its distinctive way, analyses the strong commitment of (...) law to objectivity, shedding light on the controversies that surround it. (shrink)

This volume provides a unique overview of methodologies that are conducive to a successful legal transplant in East Asia and Oceania. Each chapter is drafted by a scholar who holds direct professional experience on the legal transplant considered and has a distinctive insight into the pragmatic difficulties related to grafting an alien institution into a legal tradition. The range of transplants includes the implementation of contractual obligations, the regulation of commercial investments and the protection of the environment. The majority of (...) recent legal reforms in these geographical areas have aimed at improving national economic performance and fostering trade and have been directly inspired by European and North American institutional experiences. There is also, however, a tendency to couple economic reforms, aimed at attracting foreign investment, with constitutional reforms that improve the protection of individual rights, the environment and the rule of law.

Attachment is an emotional bond between two people where one seeks care from the other. In the prototypical case, the child attaches to their mother. The most recent theoretical developments point out that attachment is multidimensional – meaning that the phenomenon pertains to multiple domains related to the relationship with the caregiver. However, researchers have so far modeled attachment computationally by mostly adopting a classical categorical (as opposed to dimensional) standpoint that sees the system as controlling caregiver proximity. In contrast, (...) we adopt here adimensional perspective(DP) and consider dimensions to be the system’s set-goals. We hypothesize that the resulting multidimensional controller should lead to valid (or even better) models of the phenomenon. To start testing this hypothesis, we built a DP-informed agent-based model of attachment inspired by the widely-studied Strange Situation Procedure. In this context, child and mother show the nature of attachment bonds through their behavioral and emotional expressions. By modeling them as point-agents moving in a two-dimensional arena, we simulated child-mother interactions for the avoidant and ambivalent attachment dimensions. The generated dynamical patterns – characterized by the alternation between approach and exploration – matched those described in the attachment literature, thereby confirming the implementability and validity of the DP.

This article presents for the first time in english lesniewski's analysis of russell's antinomy as the analysis is given in lesniewski's 1914 paper "czy klasa klas, nie podporzadkowanych sobie, jest podporzadkowana sobie?" is the class of classes which are not subordinate to themselves subordinate to itself? it is shown how the concepts appearing in this paper, written in colloquial polish, were later incorporated and expressed as fundamental axioms and theorems of his theory of collective classes, mereology. in the 1914 paper (...) he asserted: i call any object p an object subordinate to a class k if in some sense of the expression "a" the following two conditions hold: 1) k is a class (of objects) "a", 2) p is an "a". using this explication of "p is subordinate to a class k," he showed that both of the following statements are false: a) the class of classes which are not subordinate to themselves is subordinate to itself, b) the class of classes which are not subordinate to themselves is not subordinate to itself; thus showing that russell's antinomy cannot be generated since its initial assumptions are false.

We investigated the contributions of familiarity of setting, self-relevance and self-projection in time to episodic future thinking. The role of familiarity of setting was assessed, in Experiment 1, by comparing episodic future thoughts to autobiographical future events supposed to occur in unfamiliar settings. The role of self-relevance was assessed, in Experiment 2, by comparing episodic future thoughts to future events involving familiar others. The role of self-projection in time was assessed, in both Experiments, by comparing episodic future thoughts to autobiographical (...) events that were not temporal in nature. Results indicated that episodic future thoughts were more clearly represented than autobiographical future events occurring in unfamiliar setting and future events involving familiar others. Our results also revealed that episodic future thoughts were indistinguishable from autobiographical atemporal events with respect to both subjective and objective detail ratings. These results suggest that future and atemporal events are mentally represented in a similar way. (shrink)

The concept of judicial objectivity is a cornerstone of modern legal systems. This article discusses the interplay between the lexical uses of the concept of judicial objectivity in cases that review the judicial impartiality of the court. The data for this project is retrieved from a large sample of cases from Hungary, Italy, Lithuania, Slovakia, Slovenia, Spain and the UK. The analysis of the data shows that in the case of alleged judicial bias, the concept of objectivity is referred to (...) in order to justify a series of judicial activities. In particular, the study provides a strong indication of what Legrand called ‘pre-judices’, which are the cultural aspects that are embedded in the process of the professional socialisation of each legal system.

L’articolo mette in luce due paradossi, il primo dei quali è dato dal fatto che proprio in quelle terre dove si affermò la radicale impostazione anti-umanistica del protestantesimo ebbe a scaturire una straordinaria fioritura dell’umano fino alla consacrazione della libertà come principio della ricerca scientifica e del vivere civile. Il secondo paradosso è dato dalla manifestazione in quelle stesse terre meno di un secolo fa dell’ideologia nazista. La tesi sostenuta è che il principio protestante di fatto affermatosi nella coscienza europea (...) consiste non tanto nella teoria teologica della giustificazione (sola Gratia, sola Fide, sola Scriptura) quanto nella affermazione filosofica e politica della libera coscienza personale, il cui evento decisivo fu la dichiarazione di Lutero alla Dieta di Worms. Ma proprio il carattere abissale della libertà e il destino di interpretazione infinita cui la consegnò Lutero sono anche all’origine di quel disagio della coscienza e dell’esistenza da cui sorse il malessere che portò al totalitarismo.Nel sostenere la tesi enunciata l’articolo si struttura secondo quattro movimenti: 1) argomentazione sul carattere radicalmente anti-umanistico del protestantesimo; 2) argomentazione sui notevoli effetti umanistici storicamente prodotti dalla Riforma protestante; 3) argomentazione sulle possibili connessioni tra il terreno preparato dalla Riforma nella società tedesca e il sorgere in essa dell’ideologia nazionalsocialista; 4) considerazioni finali sulla dialettica della libertà umana.

Habermas proposes a new solution to the problematic relation between republican values and democracy. He asserts that a new model of social cohesion is needed and he suggests that the sense of community in a democratic society should be founded exclusively on the acceptance and support of a system of constitutionally established rules which are the logical result of the historical evolution of constitution-making. He argues that an account of the constitutional process which led to the formation of the modern (...) republican state should provide the criteria for a rational set of norms which will exclude nationalism from the political arena. In this article, I point out the democratic hazards and the internal incoherence of Habermass alternative to the national state and I argue that a theoretical substitute should consider the existence of national identities as one of the aspects of modern pluralistic society.

In questo articolo si descrivono e discutono le caratteristiche principali della lingua quechua relative alla distinzione tra ‘maschio’ e ‘femmina’. La prima parte del testo indica il modo in cui il quechua codifica questa distinzione attraverso il lessico, ponendo l’attenzione sui termini di parentela; la seconda parte mostra i sostantivi, aggettivi e verbi indicanti persone, comportamenti e abitudini considerati come tipicamente femminili o maschili. Sia la prima parte che la seconda sono vòlte a evidenziare alcuni fattori di tipo socio-culturale associati (...) alla distinzione linguistica tra genere femminile e maschile. (shrink)

Occupying the increasingly thin line that separates legitimate appropriation from plagiarism, remix practice raises significant ethical issues. The issue is rendered more complicated by the fact that this line frequently shifts, both in academic debates and in legal. If in large Western nations remix practice is widely considered legitimate, it is still considered necessary to add something personal to one’s sources, and if at all possible to enrich those sources in some way. This is usually considered sufficient to avoid misappropriating (...) someone else’s intellectual work. In the last few years, various legal actions in the EU and the USA have revealed a significant gap between this apparently moderate position, and the position of legislators. The purpose of this paper is to take a look at some of the most controversial positions on the issue of ‘remix ethics’, attending more closely to aesthetic implications than to political consequences.

The book examines the life and the writings of Gabriele Biondo, a secular priest who lived in the little town of Modigliana between the second half of the fifteenth century and the first decades of the sixteenth century. Through a careful examination of his writings and the sources he used, this book allows the reader to obtain a more precise understanding of Biondo, his background, his life, his movements, the difficulties that he encountered (mainly with the ecclesiastical authorities and the (...) other members of the clergy, but also with civic leaders), and the main events of his life. Additionally, Biondo was the leader of a minor following formed by nuns, secular women, and laymen. Therefore, this book illustrates Biondo’s pastoral activity, the ideas and principles that supported his actions, and the objectives he was pursuing. Given these various objectives, this book is of interest to those scholars and academics interested in the religious tensions that swept through Europe in the years immediately preceding the Protestant Reformation and who, consequently, seek to investigate Biondo’s personal and complex answer to these tensions.

Applied Logic presents logic as a relevant tool for interpreting arguments, not simply as an abstract discipline such as mathematics or physics. Through English-language arguments that are debated today—health care, economic problems, AIDS, and so on—the author strives to give students an appreciation of logic's applicability. An appendix provides answers to selected exercises. Applied Logic and the Instructor's Manual will be of great value to those teaching elementary logic.

During 1927-1931 Leśniewski published a series of articles (169 pages) entitled 'O podstawach matematyki' [On the Foundations of Mathematics] in the journal Przeglad Filozoficzny [Philosophical Review], and an abridged English translation of this series is presented here. With the exception of this work, all of Leśniewski's publications appearing after the first World War were written in German, and hence accessible to scholars and logicians in the West. This work, however, since written in Polish, has heretofore not been accessible to most (...) Western readers, and it is hoped that this translation will encourage both the study of Leśniewski's works as well as the further development of his theories. (shrink)
