Contributions to the Eocene palaeontology and stratigraphy of Beira Alta, Portugal II - New Late Eocene mammalian remnants from Coja (Portugal) and the presence of Palaeotherium magnum Cuvier

The presence of Palaeotherium magnum in the fauna from Coja is recorded. It is well in agreement with the earlier reporting to the Montmartre level from the Ludian stage. Field data as well as compatibility with the remaining taxa and the identical fossilization of all the specimens indicate that all the vertebrate fossils come from the same horizon in the lithostratigraphic unit "Arcoses de Côja"

Miocene marine-continental correlations in the Lisbon area and some discussion related to personnal experience

Sandpit exploitation near Lisbon allowed collecting of many Miocene, non marine fossils. These sands are part of the mostly marine Miocene series in the Lower Tagus basin. The particularly favourable situation led several researchers to deal with marine-continental correlations. Difficulties often concern methodologic aspects. Some poorly based interpretations exerced a lasting influence. A critical approach is presented. Analysis requires data. Methods based upon models often lead to the temptation of fitting data in order to confirm a priori conclusions, or of mixing up data as if of equal statistic value while they have not at all the same weight. Erroneous interpretations' uncritical repetition for many years "upgraded" them into absolute truth. Another point is endemism vs. europeism. Miocene mammals from Lisbon compared well with corresponding French, contemporaneous taxa, while this was apparently not true for Spanish ones. Too much accent had been put on the endemic character of Spanish, or even regional, mammalian faunas. Nationalist bias and sensationalism also weigh, albeit negatively. Meanwhile nearly all the more evident examples as the rhinoceros Hispanotherium are discredited as Iberian endemisms. Taxa may appear as endemic just because they have not yet been found elsewhere. At least for the medium to large-sized mammals, with their huge geographic distribution, faunal differences depend much more on ecology, climate and environmental conditions. Emphasis on differences may also result from researchers that are often in a precarious situation and need very much to achieve short-term, preferably sensational results. Overvalued differences may mask real similarities. Unethic and not scientific behaviour are further enhanced by "nomina nuda" tricks that may simply be a way to circunvent or cheat the Priority Rule. On the other hand, access to communication networks may present as sensational novelties items that are not new at all, misleading the audience. A new class of "science people" arose, created by the media and not by the value of their real achievements. Discussion is presented on sedimentation processes and discontinuities that are often regarded as absolute precision dating tools, as well as on some geochemical and paleomagnetic interpretations. A very good chronologie frame has been obtained for the basin under study on the basis of an impressive set of data, providing a rather detailed and accurate frame for Miocene marine-continental correlations

The bovid from the Carriça clay-pit (Côja): a discussion

A Bovid tooth referred to in the litterature as from the same locality that yielded upper Eocene mammals belongs to a modem or probably contemporary Bos taurus (domestic cattle); it is not a fossil and certainly was not found in situ. As it may induce in confusion, it must not anymore be taken into account in future paleontological and stratigraphic work

Miocene c4tfishes (Ariidae, Bagridae) from Lisbon: a Nilotic (or Sudanian) type fauna

Miocene catfishes from Lisbon are dealt with. Two distinct sets of pectoral and dorsal pterygiophores are described. That from the Langhian V-b is referred to Arius sp. probably close to A. Beudeloti. Another set from the uppermost Burdigalian V-a may be ascribed to a bagtid, cf, Chrysichthys sp., identified for the first time in this region. The catfish and Lates association is strikingly similar to African, nilotic or sudanian ones as far as freshwaters are concerned. In marine, coastal environments, stenotherm warm-water forms (Polynemids, large barracudas and several sharks) indicate, as a model, faunas like those from Cape Verde to northern Angola. There is some gradation for brackish waters (fig. 1). Catfishes and Lates probably migrated into the Iberian Peninsule in the lower Miocene. They are unknown after Langhian V-b except for a reappearance of Arius in the middle Tortonian VII-b. Decreasing temperatures and aridity account for local extinction at least in freshwaters. Expansion of these fishes have been made easier owing to the displacement of land masses that narrowed or closed the marine waterway between Europe and Africa. Salinity tolerance is not necessarily the sole explanation for migration. Catfishes plus Lates associations colonized inland waters from both sides of the Paleomediterranean. Local extinction may have weighed more in the development of modern distribution patterns than migration

A Descriptive Study Utilizing Grounded Theory: The Moral-Reasoning Process of Coaches

After nearly four decades of coach education in Canada concern is being voiced about the apparent erosion of moral values amongst many coaches or, at the very least, their moral ambivalence. A database search of the literature and research findings on moral development generally espouses some sort of stage theory (Haan, 1977; Kohlberg, 1958; Weiss, 1987). Through a separate line of inquiry one can find an interest in understanding how coaches learn. Gilbert and Trudel (1999) have researched extensively the impact of experiential learning (Kolb, 1984) and critical reflection (Schön, 1991) on the learning process specifically related to coaching. The intersection of these two lines of research leads to the question of how the moral-reasoning of coaches, in competitive situations, is mediated by the specific sport-based context of their experience. p.MsoNormal, li.MsoNormal, div.MsoNormal { margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: Times New Roman ; }p.MsoBodyText, li.MsoBodyText, div.MsoBodyText { margin: 0in 0in 6pt; font-size: 12pt; font-family: Times New Roman ; }span.BodyTextChar { }div.Section1 { page: Section1; } This study utilized the varied cartographic visual mapping techniques developed by Clarke (2005) and described as situational maps, relational analyses, social worlds/arenas maps, etc., which provided the method for analysing the data from interviews and artefacts. Participants’ experiences were explored using self-identified challenging moral dilemmas through a qualitative methodology employing the grounded theory method following the situational analysis (Clarke, 2005) theoretical framework. Grounded theory by its very design is a conceptual framework. Situational analysis provides some structural concepts that, thanks to Clarke (2005), now exist in the literature but it is still conceptual in nature. @font-face { font-family: Times ; }p.MsoNormal, li.MsoNormal, div.MsoNormal { margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: Times New Roman ; }p.MsoBodyText, li.MsoBodyText, div.MsoBodyText { margin: 0in 0in 6pt; font-size: 12pt; font-family: Times New Roman ; }span.BodyTextChar { }div.Section1 { page: Section1; } The results indicate that the seemingly eclectic approach to moral-reasoning exhibited by coaches is in fact a complex system of analysis that leads to solutions. The process considers public perception, concepts of universal opportunity as well as short and long-term impact on the specific sport as well as the sport community as a whole. Based the results I was able to develop a model explaining the moral-reasoning employed by the participants in this study. Further research may determine if this can be generalized to a broader segment of the coaching profession. I hope that this model will help coach educators develop better programs to teach coaches about making moral decisions
