Critical reappraisal of Late Mesozoic-Cenozoic Central and North Atlantic, Caribbean and Mediterranean evolution

(l) The Pacific basin (Pacific area) may be regarded as moving eastwards like a double zip fastener relative to the continents and their respective plates (Pangaea area): opening in the East and closing in the West. This movement is tracked by a continuous mountain belt, the collision ages of which increase westwards. (2) The relative movements between the Pacific area and the Pangaea area in the W-E/E-W direction are generated by tidal forces (principle of hypocycloid gearing), whereby the lower mantle and the Pacific basin or area (Pacific crust = roof of the lower mantle?) rotate somewhat faster eastwards around the Earth's spin axis relative to the upper mantle/crust system with the continents and their respective plates (Pangaea area) (differential rotation). (3) These relative West to East/East to West displacements produce a perpetually existing sequence of distinct styles of opening and closing ocean basins, exemplified by the present East to West arrangement of ocean basins around the globe (Oceanic or Wilson Cycle: Rift/Red Sea style; Atlantic style; Mediterranean/Caribbean style as eastwards propagating tongue of the Pacific basin; Pacific style; Collision/Himalayas style). This sequence of ocean styles, of which the Pacific ocean is a part, moves eastwards with the lower mantle relative to the continents and the upper-mantle/crust of the Pangaea area. (4) Similarly, the collisional mountain belt extending westwards from the equator to the West of the Pacific and representing a chronological sequence of collision zones (sequential collisions) in the wake of the passing of the Pacific basin double zip fastener, may also be described as recording the history of oceans and their continental margins in the form of successive Wilson Cycles. (5) Every 200 to 250 m.y. the Pacific basin double zip fastener, the sequence of ocean styles of the Wilson Cycle and the eastwards growing collisional mountain belt in their wake complete one lap around the Earth. Two East drift lappings of 400 to 500 m.y. produce a two-lap collisional mountain belt spiral around a supercontinent in one hemisphere (North or South Pangaea). The Earth's history is subdivided into alternating North Pangaea growth/South Pangaea breakup eras and South Pangaea growth/North Pangaea breakup eras. Older North and South Pangaeas and their collisional mountain belt spirals may be reconstructed by rotating back the continents and orogenic fragments of a broken spiral (e.g. South Pangaea, Gondwana) to their previous Pangaea growth era orientations. In the resulting collisional mountain belt spiral, pieced together from orogenic segments and fragments, the collision ages have to increase successively towards the West. (6) With its current western margin orientated in a West-East direction North America must have collided during the Late Cretaceous Laramide orogeny with the northern margin of South America (Caribbean Andes) at the equator to the West of the Late Mesozoic Pacific. During post-Laramide times it must have rotated clockwise into its present orientation. The eastern margin of North America has never been attached to the western margin of North Africa but only to the western margin of Europe. (7) Due to migration eastwards of the sequence of ocean styles of the Wilson Cycle, relative to a distinct plate tectonic setting of an ocean, a continent or continental margin, a future or later evolutionary style at the Earth's surface is always depicted in a setting simultaneously developed further to the West and a past or earlier style in a setting simultaneously occurring further to the East. In consequence, ahigh probability exists that up to the Early Tertiary, Greenland (the ArabiaofSouth America?) occupied a plate tectonic setting which is comparable to the current setting of Arabia (the Greenland of Africa?). The Late Cretaceous/Early Tertiary Eureka collision zone (Eureka orogeny) at the northern margin of the Greenland Plate and on some of the Canadian Arctic Islands is comparable with the Middle to Late Tertiary Taurus-Bitlis-Zagros collision zone at the northern margin of the Arabian Plate.

Hymenoptera.

We present the fi rst review of Hymenoptera alien to Europe. Our study revealed that nearly 300 species of Hymenoptera belonging to 30 families have been introduced to Europe. In terms of alien species diversity within invertebrate orders, this result ranks Hymenoptera third following Coleoptera and Hemiptera. Two third of alien Hymenoptera are parasitoids or hyperparasitoids that were mostly introduced for biological control purposes. Only 35 phytophagous species, 47 predator species and 3 species of pollinators have been introduced. Six families of wasps (Aphelinidae, Encyrtidae, Eulophidae, Braconidae, Torymidae, Pteromalidae) represent together with ants (Formicidae) about 80% of the alien Hymenoptera introduced to Europe. Th e three most diverse families are Aphelinidae (60 species representing 32% of the Aphelinid European fauna), Encyrtidae (55) and Formicidae (42) while the Chalcidoidea together represents 2/3 of the total Hymenoptera species introduced to Europe. Th e fi rst two families are associated with mealybugs, a group that also included numerous aliens to Europe. In addition, they are numerous cases of Hymenoptera introduced from one part of Europe to another, especially from continental Europe to British Islands. Th ese introductions mostly concerned phytophagous or gall- maker species (76 %), less frequently parasitoids. Th e number of new records of alien Hymenoptera per year has shown an exponential increase during the last 200 years. Th e number of alien species introduced by year reached a maximum of 5 species per year between 1975 and 2000. North America provided the greatest part of the hymenopteran species alien to Europe (96 species, 35.3%), followed by Asia (84 species, 30.9%) and Africa (49 species, 18%). Th ree Mediterranean countries (only continental parts) hosted the largest number of alien Hymenoptera: Italy (144 spp.), France (111 spp.) and Spain (90 spp.) but no correlation was found with the area of countries. Intentional introduction, mostly for biological control, has been the main pathway of introduction for Hymenoptera. Consequently, the most invaded habitats are agricultural and horticultural as well as greenhouses. To the contrary, Hymenoptera alien in Europe are mostly associated with woodland and forest habitats. Ecological and economic impacts of alien Hymenoptera have been poorly studied. Ants have probably displaced native species and this is also true for introduced parasitoids that are suspected to displace native parasitoids by competition, but reliable examples are still scarce. Th e cost of these impacts has never been estimated.

A aceitação do registo de saúde electrónico pelos profissionais de saúde das instituições hospitalares

RESUMO: O Registo de Saúde Electrónico (RSE) detém uma importância vital para a melhoria dos cuidados e segurança do doente, para o acesso à sua informação, por profissionais de saúde, independentemente do momento e local de prestação dos cuidados clínicos, para a garantia da confidencialidade dos dados e para a redução da despesa dos serviços de saúde. É com base nesta sua importância que, no âmbito do Mestrado em Gestão da Saúde, da Escola Nacional de Saúde Pública, desenvolvemos um trabalho de investigação, que tem como objectivos descrever o “estado da arte” dos sistemas de informação em saúde e do RSE em Portugal, Europa e América do Norte, identificar a importância do RSE para os profissionais de saúde e para o doente, e avaliar a influência de determinados factores na aceitação do RSE por parte dos profissionais de saúde. Para certos autores, os factores condicionantes da aprovação do RSE podem ser: a idade, a formação, os conhecimentos informáticos, o tempo de exercício profissional e a compreensão dos benefícios do RSE por parte dos profissionais de saúde. Desta forma, elegemos estes factores para determinar se de facto são estes os que incitam a aceitação do RSE. O estudo foi dirigido a directores de serviço, médicos, enfermeiros e enfermeiroschefes, de cinco hospitais nacionais. Aos 20 participantes deste estudo foi aplicado um questionário, constituído por questões fechadas, questões factuais, de opinião e de informação. A metodologia utilizada foi do tipo descritivo e os dados foram analisados quantitativamente. Foi utilizado o coeficiente de Spearman para avaliar a existência de relação entre as variáveis, e com o seu uso foi possível depreender que: não há evidência de relação entre a idade e a aceitação do RSE; o tempo de exercício profissional não determina a aprovação do RSE; há evidência de relação entre os conhecimentos informáticos e a aceitação do RSE; a formação na área de digitalização de dados condiciona a aprovação do sistema; há evidência de relação entre a opinião dos profissionais de saúde acerca da actuação do RSE e a sua aceitação por parte destes.

The role of qualitative data and systems thinking in addressing service decline in market towns

Retail services are a main contributor to municipal budget and are an activity that affects perceived quality-of-life, especially for those with mobility difficulties (e.g. the elderly, low income citizens). However, there is evidence of a decline in some of the services market towns provide to their citizens. In market towns, this decline has been reported all over the western world, from North America to Australia. The aim of this research was to understand retail decline and enlighten on some ways of addressing this decline, using a case study, Thornbury, a small town in the Southwest of England. Data collected came from two participatory approaches: photo-surveys and multicriteria mapping. The interpretation of data came from using participants as analysts, but also, using systems thinking (systems diagramming and social trap theory) for theory building. This research moves away from mainstream economic and town planning perspectives by making use of different methods and concepts used in anthropology and visual sociology (photo-surveys), decision-making and ecological economics (multicriteria mapping and social trap theory). In sum, this research has experimented with different methods, out of their context, to analyse retail decline in a small town. This research developed a conceptual model for retail decline and identified the existence of conflicting goals and interests and their implications for retail decline, as well as causes for these. Most of the potential causes have had little attention in the literature. This research also identified that some of the measures commonly used for dealing with retail decline may be contributing to the causes of retail decline itself. Additionally, this research reviewed some of the measures that can be used to deal with retail decline, implications for policy-making and reflected on the use of the data collection and analysis methods in the context of small to medium towns.

AS COSTUREIRAS, AS QUEENS E OS SEUS MANTOS: DESTERRITORIALIZAÇÃO, CULTURA MATERIAL E CONSTRUÇÃO DO LUGAR

Durante as décadas de 1980 e de 1990 a noção de lugar foi, na literatura antropológica, sujeita a uma abordagem crítica que debateu as dimensões metodológicas e conceptuais envolvidas na sua construção. No seguimento dessa abordagem, surgiram propostas de trabalho que, de maneiras muito diversas, conseguiram ultrapassar as limitações das concepções mais clássicas da figura do lugar. Essas propostas revelaram, no entanto, que mesmo quando estamos face a uma lógica de desterritorialização, a figura do lugar pode reaparecer (embora obviamente transmutada, visto construir-se no interior de outras lógicas sociais, culturais e económicas). Partindo de uma etnografia realizada na Ilha do Pico, o texto explora algumas das inovações, provenientes dos EUA no início do século XX, que foram introduzidas nas Festas do Espírito Santo. A principal inovação prende-se com a emergência de novos personagens: as rainhas (“queens”) coroadas durante o ritual, seguidas pelas costureiras indispensáveis à confecção dos seus vestidos e mantos. Centrado nos processos de feitura dos mantos, o texto pretende mostrar como a cultura material local se constrói e se transforma no interior de um movimento transcontinental constante de pessoas, rituais, coisas e técnicas. Num contexto transnacional, a mobilidade das pessoas pode objetificar-se em coisas que são feitas localmente, participando assim a desterritorialização na construção do lugar.

Objects that move: Japanese Namban screens in the realm of the senses

This paper identifies and critiques the value of stillness as a necessary condition for the display and appreciation of art objects like the 16th century Japanese Namban screens, whose history and function is characterised by forms of movement. Drawing on multi-sited fieldwork in museum galleries that display these screens in Japan, Portugal and North America I will detail how the art-historical interpretation of the physical passage of these objects and their value as cultural heritage is based upon the fixed point perspectivism of networks and a visualist paradigm. Museum focused processes of conservation and display can be understood as extending this paradigm. By means of environmental controls, directed towards the location of perceptible meaning in what is available to vision and the necessary attenuation of the other senses the material movements of the object and movements of constituent materials in the object are stilled. The argument is for a sensory approach to museums and the objects within them, which in this case takes account of the material movements of the screens by engaging the senses through the ‘touch of sound’ as well as vision.
