Forestry in general and logging in particular continue to be among the three most hazardous sectors in European countries. The aim of this article is to characterize health and safety problems and solutions in E.U. forestry operations, and particularly in Portuguese operations. Forest types, production, employment and ownership are used to characterize the forest sector. Forestry accidents and health problems data are mentioned. Typical hazards associated to the nature of logging operations are systematized. Preventive measures, focused on a wide spectrum of measures, making safety considerations an integral feature of all operational activities from planning to organization to execution and supervision of work are emphasized in this article.

The Upper Cenomanian and Lower Turonian ammonite assemblages from the onshore sectors of the West Portuguese Margin are reviewed after new studies on the type section of Figueira da Foz, and correlative sections of Baixo Mondego. The faunal succession shows a strong contribution of vascoceratids and other ammonites with North African and Tethyan affinities. Euomphaloceras septemseriatum (Cragin, 1893), Kamerunoceras douvillei (Pervinquere, 1907), Fagesia catinus (Mantell, 1822), Neoptychites cephalotus (Courtiller, 1860), and Thomasites rollandi (Thomas & Peron, 1889) are for the first time mentioned to Portugal. The Upper Cenomanian is recognised after a set of 3 assemblage zones: Neolobites vibrayeanus z., Euomphaloceras septemseriatum z ., and Pseudaspidoceras pseudonodosoides z. The carbonate succession shows an important unconformity across the Cenomanian-Turonian boundary, associated to subaerial exposure, and to the development of a palaeokarst over Upper Cenomanian units. The first Lower Turonian carbonates are yielded a single but diverse ammonite assemblage of middle Lower Turonian age (Thomasites rollandi z.). This biozone was previously recognised in Central Tunisia by G. Chancellor et al. (1994).

A new species of terrestrial gastropod - Anadromus penai sp. nov. (Fam. Anadromidae) - is described from a set of composite moulds collected in reddish silts and clays of Campanian-Maastrichtian age, found in the lower pan of the Taveiro Formation (Taveiro, Coimbra, West Central Portugal). The known occurrences of this new species are restricted to the type locality. The main differences from other contemporaneous Anadromidae are the profuse spiral sculpture of the body-whorl, with 20-22 sub-equal, close, and regular ribs.

A collection of fossil gastropods and bivalves assembled at the Thanetian/Ypresian vertebrate site of Silveirinha (Figueira da Foz, West Central Portugal) is analysed from the point of view of systematics and palaeoecology. The diversity is scarce but the age and exceptional characteristics of the site are factors that substantiate a detailed study. The taxa identified are: Bithynia soaresi sp. nov., Gyraulus antunesi sp. nov., Chlamys sp. and Cardiiacea gen. sp. indet. The prevailing of freshwater gastropods and the occurrence of 2 fragments of marine bivalves suggest a palaeoenvironmental setting that is in conformity with interpretations already established, which are based both in sedimentologic and vertebrate data. These interpretations point out the existence of a freshwater environment opened from time to time to marine influences, resulting from a palaeoatlantic coast placed some kilometres westwards.

Among the Pleistocene and Holocene units recorded near the marine cliffs of Cape Mondego (Figueira da Foz, West Central Portugal) stands out the Farol Deposit (Depósito do Farol), at an altitude of ±95 m above present sea level. It is a marine terrace with three exposures of interstratified conglomerates and sands, overlapped by calclititic-fanglomerates. This sedimentary setting indicates that deposition took place in a seashore environment influenced by the proximity of a marine palaeocliff. The deposit has an interesting subfossil fauna with abraded and fragmented shells of Nucella lapillus (LINNÉ, 1758), Patella vulgata (LINNÉ, 1758) and Littorina littorea (LINNÉ, 1758), suggesting the existence of an environment with colder surface seawater, when compared with the present day Portuguese seashore. These specimens belonged to marine communities adapted to live in intertidal rocky platforms, which have been exposed to the cyclic action of waves and tidal flows, on the swash and surf zones. The Farol Deposit can be related to an Early/Middle Pleistocene “cold-water” episode, earlier to the Isotopic Stages 7 and 11. This episode occurred before the deposition of the units Quiaios Sands (Areias de Quiaios) and Cantanhede Sands (Areias de Cantanhede) (Sicilian?), but later than the Arazede Sands (Areias de Arazede) and Marinha das Ondas Sands (Areias de Marinha das Ondas) (Early Pleistocene).

O autor analisa a recriação das Festas dos Espírito Santo pelas comunidades açorianas dos E.U.A. na viragem do século XXI, nomeadamente a tensão entre fidelidade à tradição e inovação. A retórica tradicionalista e etnomimética coexiste com um conjunto de adaptações ao novo contexto social e cultural. Nas sociabilidades subjacentes à Festa, o protagonismo de círculos sociais da terra de origem - a família, o parentesco, a freguesia - convive com a importância das novas identidades forjadas na imigração.

Desde finais do século XIX que se desenvolveu, nos estados norte- -americanos de Massachusetts (MA) e de Rhode Island (RI), uma importante comunidade de origem portuguesa. De acordo com o censo norte-americano de 1990, essa comunidade é composta por um total de 320.000 pessoas de portuguese ancestry. Tendo sido freqüentemente descrita como uma minoria étnica "invisível" (cf Smith, 1978), ela tem entretanto uma presença importante em cidades como Fali River e New Bedford - no sudeste de Massachusetts - ou East Providence - Rhode Island - onde representa entre 40 a 55% da população total. Chegada aos EUA em duas vagas sucessivas - a primeira situada entre 1870 e 1930, a segunda entre 1960 e 1980 - esta comunidade é originária, em cerca de 90% dos casos, do arquipélago dos Açores. Dada esta sua ascendência açoriana, os imigrantes portugueses nos EUA mantêm laços importantes com a cultura do arquipélago, que, como se sabe, ao mesmo tempo que possui bastantes pontes com a cultura portuguesa mais geral, apresenta também inúmeras particularidades.

In this article we intend to make a summary overview of the influence that literary production, originated under colonial mapping missions or later in travel writing, had in the construction and establishment of a discourse to advertise and promote tourism in Mauritania. To this end we will draw on travel narratives that are illustrative of different periods and that correspond in some way to discourses of otherness. In this specific case, such discourses relate to the “Moors” of the West African coast and were produced in various historical contexts. We will also consider the discourse present in the tourism promotion materials of the colonial period and we will demonstrate to what extent it can be engaged in a dialogue with 19th and 20th centuries’ Western colonial literature.
