This article intends to rationally reconstruct Locke`s theory of knowledge as incorporated in a research program concerning the nature and structure of the theories and models of rationality. In previous articles we argued that the rationalist program can be subdivided into the classical rationalistic subprogram, which includes the knowledge theories of Descartes, Locke, Hume and Kant, the neoclassical subprogram, which includes the approaches of Duhem, Poincare and Mach, and the critical subprogram of Popper. The subdivision results from the different views of rationality proposed by each one of these subprograms, as well as from the tools made available by each one of them, containing theoretical instruments used to arrange, organize and develop the discussion on rationality, the main one of which is the structure of solution of problems. In this essay we intend to reconstruct the assumptions of Locke`s theory of knowledge, which in our view belongs to the classical rationalistic subprogram because it shares with it the thesis of the identity of (scientific) knowledge and certain knowledge.

Patterns of association of digenean families and their mollusc and vertebrate hosts are assessed by way of a new database containing information on over 1000 species of digeneans for lift-cycles and over 5000 species from fishes. Analysis of the distribution of digenean families in molluscs suggests that the group was associated primitively with gastropods and that infection of polychaetes, bivalves and scaphopods are all the results of host-switching. For the vertebrates. infections of agnathans and chondrichthyans are apparently the result of host-switching from teleosts. For digenean families the ratio of orders of fishes infected to superfamilies of molluscs infected ranges from 0.5 (Mesometridae) to 16 (Bivesiculidae) and has a mean of 5.6. Individual patterns of host association of 13 dipenean families and superfamilies are reviewed. Two, Bucephalidae and Sanguinicolidae. are exceptional in infecting a range of first intermediate hosts qualitatively as broad as their range of definitive hosts. No well-studied taxon shows narrower association with vertebrate than with mollusc clades. The range of definitive hosts of digeneans is characteristically defined by eco-physiological similarity rather than phylogenetic relationship. The range of associations of digenean families with mollusc taxa is generally much narrower. These data are considered in the light of ideas about the significance of different forms of host association. If Manter's Second Rule (the longer the association with a host group, the mure pronounced the specificity exhibited by the parasite group) is invoked, then the data may suggest that the Digenea first parasitised molluscs before adopting vertebrate hosts. This interpretation is consistent with most previous ideas about the evolution of the Digenea but contrary to current interpretations based on the monophyly of the Neodermata. The basis of Manter's Second Rule is. however, considered too flimsy for this interpretation to be robust. Problems of the inference of the evolution of patterns of parasitism in the Neodermata al-e discussed and considered so intractable that the truth may be presently unknowable.

The rapid growth in genetics and molecular biology combined with the development of techniques for genetically engineering small animals has led to increased interest in in vivo small animal imaging. Small animal imaging has been applied frequently to the imaging of small animals (mice and rats), which are ubiquitous in modeling human diseases and testing treatments. The use of PET in small animals allows the use of subjects as their own control, reducing the interanimal variability. This allows performing longitudinal studies on the same animal and improves the accuracy of biological models. However, small animal PET still suffers from several limitations. The amounts of radiotracers needed, limited scanner sensitivity, image resolution and image quantification issues, all could clearly benefit from additional research. Because nuclear medicine imaging deals with radioactive decay, the emission of radiation energy through photons and particles alongside with the detection of these quanta and particles in different materials make Monte Carlo method an important simulation tool in both nuclear medicine research and clinical practice. In order to optimize the quantitative use of PET in clinical practice, data- and image-processing methods are also a field of intense interest and development. The evaluation of such methods often relies on the use of simulated data and images since these offer control of the ground truth. Monte Carlo simulations are widely used for PET simulation since they take into account all the random processes involved in PET imaging, from the emission of the positron to the detection of the photons by the detectors. Simulation techniques have become an importance and indispensable complement to a wide range of problems that could not be addressed by experimental or analytical approaches.

The academic debate about the secession of a territory which is part of a liberal democracy state displays an initial contrast. On the one hand, practical secessionist movements usually legitimize their position using nationalist arguments linked to the principle of national self- determination. On the other hand, we find in academia few defenders of a normative principle of national self-determination. Philosophers, political scientists and jurists usually defend the status quo. And even when they do not defend it, most of them tend to leave the question of that question and secession unresolved or confused. Regarding this issue, liberal-democratic theories show a tendency to be “conservative” in relation to the political borders, regardless the historical and empirical processes of creation of current States. Probably, this feature is not far away to the fact that, since its beginning, political liberalism has not been a theory of the nation, but a theory of the state.

BACKGROUND: Truth-telling is a complex task requiring multiple skills in communication, understanding, and empathy. Its application in the context of breaking bad news (BBN) is distressing and problematic if conducted with insufficient skills. PURPOSE: We investigated the long-term influence of a simulated patient-based teaching intervention integrating the learning of communication skills within an ethical reflection on students' ethical attitudes towards truth-telling, perceived competence and comfort in BBN. METHODS: We followed two cohorts of medical students from the preclinical third year to their clinical rotations (fifth year). We analysed their ethical attitudes and level of comfort and competence in BBN before, after the intervention, and during clinical rotations. RESULTS: Students' ethical attitudes towards truth-telling remained stable. Students feeling uncomfortable or incompetent improved their level of perceived comfort or competence after the intervention, but those feeling comfortable or competent became more aware of the difficulty of the situation, and consequently decreased their level of comfort and competence. CONCLUSIONS: Confronting students with a realistic situation and integrating the practice of communication skills within an ethical reflection may be effective in maintaining ethical attitudes towards truth-telling, in developing new skills and increasing awareness about the difficulty and challenges of a BBN situation.
