'Natural concepts' in the spatial topological domain - adpositional meanings in crosslinguistic perspective: An exercise in semantic typology
Most approaches to spatial language have assumed that the simplest spatial notions are (after Piaget) topological and universal (containment, contiguity, proximity, support, represented as semantic primitives suchas IN, ON, UNDER, etc.). These concepts would be coded directly in language, above all in small closed classes suchas adpositions—thus providing a striking example of semantic categories as language-specific projections of universal conceptual notions. This idea, if correct, should have as a consequence that the semantic categories instantiated in spatial adpositions should be essentially uniform crosslinguistically. This article attempts to verify this possibility by comparing the semantics of spatial adpositions in nine unrelated languages, with the help of a standard elicitation procedure, thus producing a preliminary semantic typology of spatial adpositional systems. The differences between the languages turn out to be so significant as to be incompatible withstronger versions of the UNIVERSAL CONCEPTUAL CATEGORIES hypothesis. Rather, the language-specific spatial adposition meanings seem to emerge as compact subsets of an underlying semantic space, withcertain areas being statistical ATTRACTORS or FOCI. Moreover, a comparison of systems withdifferent degrees of complexity suggests the possibility of positing implicational hierarchies for spatial adpositions. But such hierarchies need to be treated as successive divisions of semantic space, as in recent treatments of basic color terms. This type of analysis appears to be a promising approachfor future work in semantic typology
A summary reconstruction of Proto-Maweti-Guarani segmental phonology
This paper presents a succinct reconstruction of the segmental phonology of Proto-Maweti-Guarani, the hypothetical protolanguage from which modern Mawe, Aweti and the Tupi-Guarani branches of the Tupi linguistic family have evolved. Based on about 300 cognate sets from the authors' field data (for Mawe and Aweti) and from Mello's reconstruction (2000) for Proto-Tupi-Guarani (with additional information from other works; and with a few changes concerning certain doubtful features, such as the status of stem-final lenis consonants ∗r and ∗β, and the distinction of ∗c and ∗č), the consonants and vowels of Proto-Maweti-Guarani were reconstructed with the help of the traditional historical-comparative method. The development of the reconstructed segments is then traced from the protolanguage to each of the modern branches. A comparison with other claims made about Proto-Maweti-Guarani is given in the conclusio
Coherent and semiclassical states in magnetic field in the presence of the Aharonov-Bohm solenoid
A new approach to constructing coherent states (CS) and semiclassical states
(SS) in magnetic-solenoid field is proposed. The main idea is based on the fact
that the AB solenoid breaks the translational symmetry in the xy-plane, this
has a topological effect such that there appear two types of trajectories which
embrace and do not embrace the solenoid. Due to this fact, one has to construct
two different kinds of CS/SS, which correspond to such trajectories in the
semiclassical limit. Following this idea, we construct CS in two steps, first
the instantaneous CS (ICS) and the time dependent CS/SS as an evolution of the
ICS. The construction is realized for nonrelativistic and relativistic spinning
particles both in (2+1)- and (3+1)- dimensions and gives a non-trivial example
of SS/CS for systems with a nonquadratic Hamiltonian. It is stressed that CS
depending on their parameters (quantum numbers) describe both pure quantum and
semiclassical states. An analysis is represented that classifies parameters of
the CS in such respect. Such a classification is used for the semiclassical
decompositions of various physical quantities.Comment: 35 pages, 2 figures. Some typos in (77), (101), and (135) corrected

Occupational risk in a glass manufacturing industry unit
Risk assessment is one of the main pillars of the framework directive
and other directives in respect of health and safety. It is also the basis
of an effective management of safety and health as it is essential to
reduce work-related accidents and occupational diseases. To survey
the hazards eventually present in the workplaces the usual
procedures are i) gathering information about tasks/activities,
employees, equipment, legislation and standards; ii) observation of
the tasks and; iii) quantification of respective risks through the most
adequate risk assessment among the methodologies available. From
this preliminary evaluation of a welding plant and, from the different
measurable parameters, noise was considered the most critical.
This paper focus not only the usual way of risk assessment for noise
but also another approach that may allow us to identify the technique
with which a weld is being performed
