Suidés et tayassuidés du burdigalien V-a et du langhien V-b de lisbonne

Teeth and astragali were used for a biometrical study concerning suids from V-a (upper Burdigalian) and V-b (Langhian) divisions from Lisbon's Miocene series. The Hyotherium (V-b) are identical to those from french localities, hence they all belong in the same species H. soemmeringi. Bunolistriodon populations from V-a and V-b are homogenous; no significant difference between them has been found, inspite of different geological age. Both may be ascribed to B. lockharti. No evolutive trend was detected. The presence of another form close to the north african B. massai could not be confirmed either. French localities' Bunolistriodon populations also seem homogenous and conspecific with those from Lisbon. Notwithstanding its essentially homogenous character, there can be distinguished two sets in both V-a and V-b populations according to M3 size; this remains to be explained, since the last molars are the most likely to show a broad range of variation and are not unequivocally related to sexual dimorphism. Classification of the rare Tayassuidae has been confirmed. All known taxa are shown (see tableau I).

Représentation du sexe chez N. Arcan, V. Despentes, M.-S. Labrèche et C. Millet

Depuis la fin des années 1990, une nouvelle génération d’écrivaines s’est emparée des thèmes du corps et de la sexualité. Certaines de leurs œuvres ont fait scandale pour l’impudeur qui les caractériserait, d’autres pour leur violence ou leur appartenance supposée à la pornographie. Si ces textes témoignent de changements profonds au sein de la société, ils attirent également notre attention sur leur inscription manifeste hors des catégories génériques qu’ils semblaient indiquer. Ce mémoire rend compte de la façon dont À ciel ouvert de Nelly Arcan, Baise-moi de Virginie Despentes, La brèche de Marie-Sissi Labrèche, La vie sexuelle de Catherine M. de Catherine Millet et La nouvelle pornographie de Marie Nimier traitent la thématique du corps et du sexe. La politique des corps révèle que les récits d’aujourd’hui expriment, certainement aussi fortement que dans les années 1970, la nécessité de dissoudre et de réinventer les identités sexuées. De plus, une analyse centrée sur la notion de sujet telle qu’elle s’écrit dans la relation du plaisir et du désir montre que le thème sexuel est un moyen pour les auteures d’explorer une réalité qui devient flagrante lorsque les êtres de langage se mettent à habiter leur corps. Enfin, une lecture générique souligne toute la complexité de l’utilisation de la pornographie dans les récits étudiés et s’intéresse aux stratégies de légitimation indiquant vers quelle définition de la littérature tendent les auteures.

New Perspectives on beta-Adrenergic Mediation of Innate and Learned Fear Responses to Predator Odor

In the present study, we investigated the role of noradrenergic transmission in unconditioned and conditioned responses to predatory threats. First, we examined the effects of systemically injected beta-blockers on unconditioned and contextual conditioned response to cat odor. The centrally acting beta-blocker (propranolol) was able to impair unconditioned responses, as well as the acquisition of the contextual fear to cat odor; however, the peripherally acting (nadolol) was not effective. Next, we examined the neural substrate underlying the noradrenergic modulation of the defensive response to cat odor and focused on the dorsal premammillary nucleus (PMd), because it represents the hypothalamic site most responsive to predatory threats and, at the same time, presents a dense plexus of noradrenergic fibers. We were able to see that propranolol significantly reduced PMd-Fos expression in response to cat odor and that beta-adrenoceptor blockade in the PMd, before cat odor exposure, reduced defensive responses to the cat odor and to the cat odor-related environment. We have also shown that beta-adrenoceptor blockade in the PMd, before the exposure to cat odor-related context, impaired the contextual conditioned responses. Overall, the present results provide convincing evidence suggesting that central noradrenergic mediation is critical for the expression of unconditioned and contextual conditioned antipredatory responses. We have further shown that the PMd appears to be an important locus to mediate these beta-adrenoceptor effects.

PANA V : Evaluation of a Literacy Project

PANA V Evaluation of a Literacy ProjectSUMMARY AND CONCLUSIONSThis evaluation set out to explore the impact of the literacy work carried out through PANA V. It focussed on clarifying effects such as empowerment and poverty reduction in relation to the civil society. Two specific objectives were to evaluate the methodological approach and the didactic materials and to evaluate the sustainability of the project.Although the focus of the evaluation has been PANA V, the project has been evaluated in its context, as one in a series of five projects located in Rwanda ten years after the war and genocide. The conclusion will consider future plans in this field.The evaluator has striven to create a holistic picture of the effects of the project, although the given time for the evaluation was short. Only three weeks were spent in the field study and only ten days in the actual field. Although there were some organisational and logistic problems, as is common when carrying out a study like this in a poor country, many literacy sites were visited and quite many participators were interviewed. The overall impression from the study is overwhelmingly positive. So many people commit themselves in this task of teaching Rwandans reading, writing and numeracy. Despite harsh conditions learners strive to learn and group leaders devote themselves to the task. Many leaders on different levels try their very best to manage their difficult and demanding task. The main objective was to explore the impact of the project on poverty reduction, particularly on empowerment and strategies for everyday life. Women were to be regarded particularly. From the results it is clear that the project has a strong, positive impact both on poverty reduction and empowerment of marginalised groups. Among those who have benefited from the alphabetisation are mainly women. Unfortunately, when it comes to leaders in PANA, who may also be said to have benefited from the project, only a small minority is women. This is something that is recommended that it be reconsidered inside the organisation. As a majority of the targeted learners are women, and as the economic and social situation of women in Rwanda is generally weak, this is a question that I recommend the Pentesostal church and ADEPR to look particularly into. With many women being single breadwinners of their households, it is important that also women get access to positions that may bring benefits of different kind.It is also clear that the project has positive effects for the civil society. In the present situation in Rwanda, during the process of reconciliation and rapid progress, basic education for the poor majority is a democratic issue. In a country with a plethora of internet-cafés in the capital and a small minority that use cars and mobile-telephones to communicate nation-wide, it is of outmost importance that the majority acquires basic education, of which literacy is a central part. To strengthen the civil society in Rwanda literacy is important. One central issue is then that Rwanda develops toward becoming a country where literacy is used for the benefit of the citizens and it is a democratic issue that all citizens get an opportunity to participate. Crucial for this is that strong efforts are put into primary schools nation-wide. Literacy projects for adults, like PANA, may only complement these efforts, but they constitute important and necessary complements. Other relevant ways to promote literacy are campaigns in Radio and TV and through cultural events such as festivals, music and theatre. News papers, magazines and books are natural parts of such campaigns as well as adult education. As stated under the results not much can be said about the didactics in this evaluation. On the whole the methodology and the materials fill their function well and receive a high reputation. As people learn to read and write under very simple conditions, obviously the approach is appropriate. A few suggestions may be given from the study:•Focus groups leaders’ attention on clearness, that they show very clearly what is to be read. Good structuring is probably of great importance for many learners.•Make clear what is tested in the tests and consider the possibility to use a holistic test that would be more congruent with the methodology. The possibility to use only one grade, pass, would enable a more practical test, such as reading a short, relevant text, writing something relevant and solving practical mathematic problems. Avoid tests that demand school knowledge.•Avoid using methaphors such as “fight against illiteracy” and connections between illiteracy/literacy and darkness/light. It is not true that illiteracy causes bad things and that literacy only brings good. •Be prepared that it may be more difficult in the future to achieve the goals as it may be the case that the early learners where the ones who achieved easily. The goal of “literacy in six month” in PANA will probably hold only for some learners but also those who do not manage in six months need literacy skills.A third objective was to secure sustainability. As for sustainability of the project in itself, and of the literacy process, the main conclusion is that there is a good potential. The commitment and devotedness among many involved in PANA proves good. One weakness is individual leaders in ADEPR who do not see this as an important task for the Pentecostal church in Rwanda. Other weaknesses are the unwillingness to mention explicitly the wish, for example among group leaders, to get some kind of incentive and the fear of loosing believers by cooperation with other organisations. A higher degree of transparency in this issue would probably solve some irritations and tensions.As for the sustainability of the literacy skills much may be done to improve. The acquired skills seem to be comparably relevant. The level achieved, and the level tested, may be defined as basic literacy skills, consisting of basic reading, writing and numeracy skills. However, these skills are very restricted and there is a high risk that the skills will decline, which means that there is a high risk that people will forget how to read and write because of lack of exercising. From these conclusions a few suggestions for future development will be given.

Interaction of shikimic acid with shikimate kinase (Retracted Article. See vol 334, pg 967, 2005)

The crystal structure of shikimate kinase from Mycobacterium tuberculosis (MtSK) complexed with MgADP and shikimic acid (shikimate) has been determined at 2.3 Angstrom resolution, clearly revealing the amino acid residues involved in shikimate binding. In MtSK, the Glu61 strictly conserved in SK forms a hydrogen bond and salt-bridge with Arg58 and assists in positioning the guanidinium group of Arg58 for shikimate binding. The carboxyl group of shikimate interacts with Arg58, Gly81, and Arg136, and hydroxyl groups with Asp34 and Gly80. The crystal structure of MtSK-MgADP-shikimate will provide crucial information for elucidation of the mechanism of SK-catalyzed reaction and for the development of a new generation of drugs against tuberculosis.

Ravenna e i piu' significativi centri dell'Impero. Il mosaico parietale tra V e VI secolo: Revisione critica

Tra il V ed il VI secolo, la città di Ravenna, per tre volte capitale, emerge fra i più significativi centri dell’impero, fungendo da cerniera tra Oriente e Occidente, soprattutto grazie ai mosaici parietali degli edifici di culto, perfettamente inseriti in una koinè culturale e artistica che ha come comune denominatore il Mar Mediterraneo, nel contesto di parallele vicende storiche e politiche. Rispetto ai ben noti e splendidi mosaici ravennati, che insieme costituiscono senza dubbio un unicum nel panorama artistico dell’età tardoantica e altomedievale, nelle decorazioni musive parietali dei coevi edifici di culto dei diversi centri dell’impero d’Occidente e d’Oriente, e in particolare in quelli localizzati nelle aree costiere, si possono cogliere divergenze, ma anche simmetrie dal punto di vista iconografico, iconologico e stilistico. Sulla base della letteratura scientifica e attraverso un poliedrico esame delle superfici musive parietali, basato su una metodologia interdisciplinare, si è cercato di chiarire l’articolato quadro di relazioni culturali, ideologiche ed artistiche che hanno interessato e interessano tuttora Ravenna e i vari centri della tarda antichità, insistendo sulla pluralità, sulla complessità e sulla confluenza di diverse esperienze artistiche sui mosaici di Ravenna. A tale scopo, i dati archeologici e artistici sono stati integrati con quelli storici, agiografici ed epigrafici, con opportuni collegamenti all’architettura, alla scultura, alle arti decorative e alle miniature, a testimonianza dell’unità di intenti di differenti media artistici, orientati, pur nella diversità, verso le medesime finalità dogmatiche, politiche e celebrative. Si tratta dunque di uno studio di revisione e di sintesi sui mosaici parietali mediterranei di V e VI secolo, allo scopo di aggiungere un nuovo tassello alla già pur vasta letteratura dedicata all’argomento.

Dafnis en la Bucólica V de Virgilio : La alusión compleja y los límites de la identidad

La mayor parte de la crítica sobre la bucólica V ha partido de la idea de que Dafnis es una alegoría de otro personaje o de otra realidad. Sin embargo, nada hay en él que haga posible sostener una interpretación alegórica en ningún sentido porque, a diferencia del puer de la bucólica IV o del iuvenis de la I, Dafnis tiene un nombre preciso. Partiendo de otros postulados críticos, la idea de este artículo es que el Dafnis de la bucólica V sugiere distintos planos de alusiones (alusión compleja), uno de los cuales es el contemporáneo, que remite a César, pero que el carácter literario del texto nos impide admitir la alegorización, basada en posiciones ajenas a la índole de los textos literarios. La reseña de distintas consideraciones críticas hace pensar que, en cierta manera, esos sentidos están presentes en el poema de Virgilio y no son necesariamente el resultado de especulaciones posteriores. Por último, puede verse que es la poesía, en tanto sostén de la historia (y con la materias de la imagen y la alusión), el ente capaz de celebrar algún aspecto del ámbito histórico. Esta idea puede extenderse a otros sectores de la obra virgiliana
