RiassuntoVengono analizzati gli aspetti socio-demografici dei meccanismi messi in opera dalle popolazioni animali per regolare la propria densità numerica.Negli animali la regolazione demografica è un fenomeno legato alla strategia finalistica della Natura. D'altro canto lo scopo principale della Natura è la continuità della specie nelle migliori condizioni di vita e di congruità nell'ambiente.Il sistema migliore per esaminare come le specie animali limitino il numero dei propri individui al fine di mantenersi in equilibrio con l'ambiente è quello di studiare le popolazioni (...) delle varie specie.L'approccio ottimale per l'analisi del divenire di una popolazione si ha esaminando la sua densità, struttura, natalità, mortalità e dispersione.Inoltre la stabilità di una popolazione nel tempo è regolata da fattori densità-dipendenti. Invece i fattori non legati alla densità possono portare all'estinzione della popolazione. Fattori densità-dipendenti sono la competizione interindividuale, la capacità riproduttiva, la emigrazione, la predazione e i rapporti sociali. Tutti questi fattori mettono in essere un insieme di automatismi tipo feed-back negativi che permettono la stabilizzazione numerica temporale della popolazione.Nel tentativo di mantenersi congrue all'ambiente le popolazioni animali mettono in opera, o subiscono sotto la spinta evolutiva, altri meccanismi di autocompensazione come: manifestazioni comportamentali come territorialismo e dominanza sociale agiscono da regolatori del numero di individui nelle popolazioni animali. Infine si puntualizza il ruolo della selezione r (tasso intrinseco di accrescimento) e k (capacità biologica specifica) nella costituzione di popolazioni rispettivamente a strategia opportunistica, che conquistano nuovi habitat, o a strategia stabile, che vivono in habitat a maggiore durata.

Per una lettura del presente volume si deve anzitutto tener presente che, come afferma esplicitamente l'A. (p.12), esso è nato come tesi di laurea; si tratta quindi di un'opera redatta quando l'A. non aveva neanche ancora iniziato il percorso di dottorato di ricerca. Questo fatto può spiegare la presenza di numerose ingenuità, affermazioni avventate, ambigue o inesatte, nonché un'impostazione del lavoro che sarebbe eccessivamente ambiziosa anche per uno studioso con qualche anno di esperienza in più. Il libro infatti si propone (...) non solo di analizzare la legislazione giustinianea in tema di schiavitù, ma anche di individuare i profili nuovi che i passi degli antichi giuristi assumono tramite il loro inserimento nel Digesto; di accertare inoltre l'impatto dei testi legislativi nella realtà sociale, al fine di verificare “se siano effettivamente stati i fattori socio-economici la principale causa del declino a quest'epoca della schiavitù, al di là dell'evoluzione legislativa subita e dell'influenza esercitata dai princìpi cristiani” (p.11).

But any reasonable scholar can recognize the disproportion between a desirable concordance and this hyperbolic system of about 70,000 pages. The Index Thomisticus is the second largest written work of this century, surpassed only by the Enrcyclopedia Britannica. The Index Thomisticus is a mountain of pages that classifies with a precision never before realized everything that came from Aquinas's pen in twenty-five years.2 Is it not awkwardly disproportionate and too pedantically analytical for scholarly research? Moreover, what would Aquinas think if, in a return to this life, he could see the electronic digestion of his work? A neoscholastic Jesuit who devoted thirty-four years of his life to chopping and classifying even the most insignificant things, like " et " and " est," could seem to St. Thomas a modern computernut, i.e., a person who has lost his good sense in front of a screen.3 Everyone understands the usefulness of a concordance; even St. Thomas wanted and used concordances.4 But the Index Thomis136.

In this paper, I reply to 18 of the essays on panpsychism in this issue. Along the way, I sketch out what a post-Galilean science of consciousness, one in which consciousness is taken to be a fundamental feature of reality, might look like.

I argue for accepting a pluralist approach to species, while rejecting the realism about species espoused by P. Kitcher and a number of other philosophers of biology. I develop an alternative view of species concepts as divisions of organisms into groups for study which are relative to the systematic explanatory interests of biologists at a particular time. I also show how this conception resolves a number of difficult puzzles which plague the application of particular species concepts.

I've previously suggested that the historical evidence used to challenge scientific realism should lead us to embrace what I call Uniformitarianism, but many recently influential forms of scientific realism seem happy to share this commitment. I trace a number of further points of common ground that collectively constitute an appealing Middle Path between classical forms of realism and instrumentalism, and I suggest that many contemporary realists and instrumentalists have already become fellow travelers on this Middle Path without recognizing how far (...) they have thereby diverged from those who share their labels and slogans. I conclude by describing their central remaining disagreement and the sorts of evidence needed to resolve it. (shrink)

Although some authors hold that natural kinds are necessarily relative to disciplinary domains, many authors presume that natural kinds must be absolute, categorical features of the reality —often assuming that without even mentioning the alternative. Recognizing both possibilities, one may ask whether the difference especially matters. I argue that it does. Looking at recent arguments about natural kind realism, I argue that we can best make sense of the realism question by thinking of natural kindness as a relation that holds (...) between a category and a domain.

Integrated information theory (IIT) is a candidate theory of consciousness that highlights the role of complex interactions between parts of a system as the basis of consciousness – and, due to its general information-theoretic formulation, is capable of making statements about consciousness in neural and non-neural systems alike. Here, we argue that a system radically different to a human brain, host to complex physiological and functional structures capable of integrating information, can be found in the meristems and vascular system of (...) higher plants. Following a pragmatic and ontologically innocent approach, neither taking for granted that plants are conscious nor dismissing the possibility that they are, we argue that the time is ripe to apply analysis tools inspired by IIT to plants, taking advantage of recent developments in both plant imaging and information theory. We introduce and discuss the relevant literature, and pro information and integration in plant behaviour, assessing the plausibility of plant sentience. If successful, these experiments could position plants as the next frontier in consciousness science, and urge us to rethink our perspectives on consciousness, how to measure it, and its prevalence amongst living beings.

Optimization by definition is the action of making most effective or the best use of a resource or situation and that is required almost in every field of engineering. In this work, the optimization of Least Mean square (LMS) algorithm is carried out with the help of Particle Swarm Optimization (PSO) and Ant Colony Optimization (ACO). Efforts have been made to find out the advantages and disadvantages of combining gradient based (LMS) algorithm with Swarm Intelligence SI (ACO, PSO). This optimization (...) of LMS algorithm will help us in further extending the uses of adaptive filtering to the system having multi-model error surface that is still a gray area of adaptive filtering. Because the available version of LMS algorithm that plays an important role in adaptive filtering is a gradient based algorithm, that get stuck at the local minima of system with multi-model error surface considering it global minima, resulting in an non-optimized convergence. By virtue of the proposed method we have got a profound solution for the problem associated with system with multimodal error surface. The results depict significant improvements in the performance and displayed fast convergence rate, rather stucking at local minima. Both the SI techniques displayed their own advantage and can be separately combined with LMS algorithm for adaptive filtering. This optimization of LMS algorithm will further help to resolve serious interference and noise issues and holds a very important application in the field of biomedical science. (shrink)

A considerable literature has grown up around the claim of Uniqueness, according to which evidence rationally determines belief. It is opposed to Permissivism, according to which evidence underdetermines belief. This paper highlights an overlooked third possibility, according to which there is no rational doxastic attitude. I call this 'Nihilism'. I argue that adherents of the other two positions ought to reject it but that it might, nevertheless, obtain at least sometimes.

What does the law demand when it requires citizens to conform to standards of reasonableness? I propose and defend the view that the law should demand that citizens conform their behavior to some actual conduct in society. I contrast this idea against what might be called the ``empty vessel'' view of reasonableness, where the standard is understood to function like an empty vessel in the law, allowing courts to use various norms and moral judgments to determine what seems reasonable in (...) the circumstances. The empty vessel account is the more common approach for understanding reasonableness, but it leaves obscure whether and how assessments about appropriate conduct connect with facts about citizens' actual conduct. I argue for a ``binocular'' view that focuses our attention on actual practices and thereby establishes how these standards provide a stable guide to conduct and support the rule of law. (shrink)
