Anthropogenic disturbance as a driver of microspatial and microhabitat segregation of cytotypes of Centaurea stoebe and cytotype interactions in secondary contact zones.

BACKGROUND AND AIMS: In a mixed-ploidy population, strong frequency-dependent mating will lead to the elimination of the less common cytotype, unless prezygotic barriers enhance assortative mating. However, such barriers favouring cytotype coexistence have only rarely been explored. Here, an assessment is made of the mechanisms involved in formation of mixed-ploidy populations and coexistence of diploid plants and their closely related allotetraploid derivates from the Centaurea stoebe complex (Asteraceae). METHODS: An investigation was made of microspatial and microhabitat distribution, life-history and fitness traits, flowering phenology, genetic relatedness of cytotypes and intercytotype gene flow (cpDNA and microsatellites) in six mixed-ploidy populations in Central Europe. KEY RESULTS: Diploids and tetraploids were genetically differentiated, thus corroborating the secondary origin of contact zones. The cytotypes were spatially segregated at all sites studied, with tetraploids colonizing preferentially drier and open microhabitats created by human-induced disturbances. Conversely, they were rare in more natural microsites and microsites with denser vegetation despite their superior persistence ability (polycarpic life cycle). The seed set of tetraploid plants was strongly influenced by their frequency in mixed-ploidy populations. Triploid hybrids originated from bidirectional hybridizations were extremely rare and almost completely sterile, indicating a strong postzygotic barrier between cytotypes. CONCLUSIONS: The findings suggest that tetraploids are later immigrants into already established diploid populations and that anthropogenic activities creating open niches favouring propagule introductions were the major factor shaping the non-random distribution and habitat segregation of cytotypes at fine spatial scale. Establishment and spread of tetraploids was further facilitated by their superior persistence through the perennial life cycle. The results highlight the importance of non-adaptive spatio-temporal processes in explaining microhabitat and microspatial segregation of cytotypes.

Evolutionary history of the greater white-toothed shrew (Crocidura russula) inferred from analysis of mtDNA, Y, and X chromosome markers.

We investigate the evolutionary history of the greater white-toothed shrew across its distribution in northern Africa and mainland Europe using sex-specific (mtDNA and Y chromosome) and biparental (X chromosome) markers. All three loci confirm a large divergence between eastern (Tunisia and Sardinia) and western (Morocco and mainland Europe) lineages, and application of a molecular clock to mtDNA divergence estimates indicates a more ancient separation (2.25 M yr ago) than described by some previous studies, supporting claims for taxonomic revision. Moroccan ancestry for the mainland European population is inconclusive from phylogenetic trees, but is supported by greater nucleotide diversity and a more ancient population expansion in Morocco than in Europe. Signatures of rapid population expansion in mtDNA, combined with low X and Y chromosome diversity, suggest a single colonization of mainland Europe by a small number of Moroccan shrews >38 K yr ago. This study illustrates that multilocus genetic analyses can facilitate the interpretation of species' evolutionary history but that phylogeographic inference using X and Y chromosomes is restricted by low levels of observed polymorphism.

Public health education in Europe: old and new challenges

The purpose of this article is to discuss some of the current challenges faced by European schools of public health. Perhaps most remarkable on the continent is the diversity, the magnitude, and the rapidity of the developments in public health education since the Second World War. This article discusses its evolution, its main characteristics and the underlying rationale with several examples. Further, it addresses specific aspects of the future development, namely the collaboration of academic schools with practice-oriented institutions, as well as the interactions between the constituent disciplines of public health. The Bologna process on post-graduate education in Europe has had an important impact on the overall design of most schools. There is a willingness to develop public health in each country of the European region and there is a need to develop common strategies to reach high standards in teaching, training and researching in all disciplines related to public health.

Case-control analysis of paternal age and trisomic anomalies.

OBJECTIVES: To determine whether older paternal age increases the risk of fathering a pregnancy with Patau (trisomy 13), Edwards (trisomy 18), Klinefelter (XXY) or XYY syndrome. DESIGN: Case-control: cases with each of these syndromes were matched to four controls with Down syndrome from within the same congenital anomaly register and with maternal age within 6 months. SETTING: Data from 22 EUROCAT congenital anomaly registers in 12 European countries. PARTICIPANTS: Diagnoses with observed or (for terminations) predicted year of birth from 1980 to 2005, comprising live births, fetal deaths with gestational age ≥ 20 weeks and terminations after prenatal diagnosis of the anomaly. Data include 374 cases of Patau syndrome, 929 of Edwards syndrome, 295 of Klinefelter syndrome, 28 of XYY syndrome and 5627 controls with Down syndrome. MAIN OUTCOME MEASURES: Odds ratio (OR) associated with a 10-year increase in paternal age for each anomaly was estimated using conditional logistic regression. Results were adjusted to take account of the estimated association of paternal age with Down syndrome (1.11; 95% CI 1.01 to 1.23). RESULTS: The OR for Patau syndrome was 1.10 (95% CI 0.83 to 1.45); for Edwards syndrome, 1.15 (0.96 to 1.38); for Klinefelter syndrome, 1.35 (1.02 to 1.79); and for XYY syndrome, 1.99 (0.75 to 5.26). CONCLUSIONS: There was a statistically significant increase in the odds of Klinefelter syndrome with increasing paternal age. The larger positive associations of Klinefelter and XYY syndromes with paternal age compared with Patau and Edwards syndromes are consistent with the greater percentage of these sex chromosome anomalies being of paternal origin.

Economic grand rounds: financial burden of medical care and risk of forgoing care among Europeans with depressive symptoms

Little is known about the financial burden of individuals with depressive symptoms. This study explored that burden, using data from the Survey of Health, Ageing, and Retirement in Europe. To assess the association between depressive symptoms and the individuals' financial burden for medical care and whether they forwent medical care because of costs, logistic regressions were performed that adjusted for age, gender, marital status, education, and chronic diseases. A total of 16,696 noninstitutionalized individuals aged 50-79 years were included in the study. Individuals with depressive symptoms and those without such symptoms bore a similar financial burden. However, individuals with depressive symptoms were at increased risk of forgoing care because of costs, which may worsen their health and financial situation

Is chytridiomycosis an emerging infectious disease in Asia?

The disease chytridiomycosis, caused by the fungus Batrachochytrium dendrobatidis (Bd), has caused dramatic amphibian population declines and extinctions in Australia, Central and North America, and Europe. Bd is associated with >200 species extinctions of amphibians, but not all species that become infected are susceptible to the disease. Specifically, Bd has rapidly emerged in some areas of the world, such as in Australia, USA, and throughout Central and South America, causing population and species collapse. The mechanism behind the rapid global emergence of the disease is poorly understood, in part due to an incomplete picture of the global distribution of Bd. At present, there is a considerable amount of geographic bias in survey effort for Bd, with Asia being the most neglected continent. To date, Bd surveys have been published for few Asian countries, and infected amphibians have been reported only from Indonesia, South Korea, China and Japan. Thus far, there have been no substantiated reports of enigmatic or suspected disease-caused population declines of the kind that has been attributed to Bd in other areas. In order to gain a more detailed picture of the distribution of Bd in Asia, we undertook a widespread, opportunistic survey of over 3,000 amphibians for Bd throughout Asia and adjoining Papua New Guinea. Survey sites spanned 15 countries, approximately 36° latitude, 111° longitude, and over 2000 m in elevation. Bd prevalence was very low throughout our survey area (2.35% overall) and infected animals were not clumped as would be expected in epizootic events. This suggests that Bd is either newly emerging in Asia, endemic at low prevalence, or that some other ecological factor is preventing Bd from fully invading Asian amphibians. The current observed pattern in Asia differs from that in many other parts of the world.

The Paleozoic magmatic history of the Maggia and Sambuco nappes, Lower Penninic, Central Lepontine Alps

Résumé : Les corps magmatiques sont des indicateurs essentiels dans toute reconstitution paléogéographique et/ou géodynamique d'un cycle orogénique, en particulier en contexte polycyclique, où la plupart des autres indices ont été oblitérés. Ils sont aisément datables et leurs caractéristiques géochimiques permettent de contraindre leur contexte tectonique de mise en place. Cette approche a été appliquée aux socles pré-mésozoïques des nappes penniques inférieures de Sambuco et de la Maggia, dans les Alpes centrales lepontines. Plusieurs événements magmatiques ont été identifiés dans le socle de Sambuco et datés par la méthode U-Pb sur zircon couplée à la technique LA-ICPMS. La suite calco-alcaline mafique rubanée de Scheggia est datée du Cambrien inférieur à 540-530 Ma ; le métagranite alumineux oeillé de Sasso Nero a un âge de 480-470 Ma, tout comme bien d'autres «older orthogneisses» des socles alpins. Il contient des zircons hérités d'âge panafricain à 630-610 Ma, indicateur d'une affiliation gondwanienne de ces terrains. Le pluton calco-alcalin du Matorello est daté à environ 300-310 Ma, et les filons lamprophyriques qu'il abrite à 300 Ma. La granodiorite de Cocco et le leucogranite de Ruscada, tous deux intrudés dans le socle de la nappe adjacente de la Maggia, ont des âges similaires à celui du Matorello. Ceci ajouté aux similitudes magmatiques observées entre Cocco et Matorello suggère une proximité paléogéographique des deux nappes au Permien-Carbonifère. Or ces dernières sont actuellement considérées appartenir à deux domaines paléogéographiques mésozoïques distincts : helvétique pour Sambuco et briançonnais pour Maggia, séparés par un bassin océanique. Si tel fut le cas, aucun mouvement décrochant ne doit avoir décalé les marges continentales de l'océan, retrouvées en parfaite coïncidence lors de sa fermeture. Le Matorello est un pluton recristallisé en faciès amphibolite et plissé par cinq phases successives de déformation non-coaxiales, qui ont conduit à son renversement complet, attesté par des indicateurs de paléogravité. Il préserve de spectaculaires phénomènes de coexistence liquide de magmas (essaims d'enclaves et Bills composites). Ce pluton était originellement tabulaire, construit par l'accumulation de multiples injections de magma en feuillets d'épaisseur métrique à décamétrique. Suivant le rythme de mise en place, les injections successives ont rapidement cristallisé avec des contours nets et bien définis (Bills composites) ou se sont mélangées avec les précédentes pour former une couche non consolidée de plusieurs dizaines de mètres d'épaisseur (granodiorite principale). Les injections individuelles sont délimitées par de subtils contrastes en granulométrie, proportions modales ou ségrégation de minéraux (schlieren), ou par des phénomènes d'érosion le long des surfaces de contact. Deux couches métriques à contour sinueux consistent en une accumulation compacte d'enclaves mafiques arrondies dans une matrice granodioritique fine. Le granoclassement des enclaves, la présence de figures de charge et de phénomènes érosifs en base de couche, ainsi que des schlieren de biotite entrecroisés évoquent l'injection de coulées de magma chargé d'enclaves et de faible viscosité en régime hydrodynamique turbulent dans un encaissant granodioritique encore largement liquide. La nature hybride des roches implique une chambre magmatique sous-jacente, en cours de différenciation et périodiquement réalimentée. Les magmas sont des liquides mafiques dérivés du manteau et des liquides anatectiques d'origine crustale, comme l'indique la gamme mesurée des rapports isotopiques initiaux du Sr (0.704 à 0.709) et des valeurs epsilon Nd (-2.1 à -4.7). Ces données montrent également que la contribution crustale est dominante, en accord avec les isotopes du plomb. Les phénomènes d'hybridation ont vraisemblablement eu lieu en base de croûte et dans la chambre magmatique sous-jacente au laccolite du Matorello. Les indicateurs de paléogravité du Matorello contribuent accessoirement à la compréhension de l'architecture actuelle de la nappe de Sambuco. Des plis isoclinaux à surface axiale verticale peuvent être mis en évidence par le contact entre les faciès dioritique et granodioritique. L'antiforme dont le Matorello forme le coeur est un synclinal, ce qui le positionne dans le Flanc inverse du grand pli couché que forme la nappe de Sambuco. Par ailleurs, des blocs de gneiss retrouvés dans le wildflysch sommital de la couverture de la nappe d'Antigorio ont été affiliés dans cette étude au pluton du Matorello. Ceci implique que le front de la nappe de Sambuco chevauchait déjà la partie est du bassin d'Antigorio au moment de sa fermeture. Par conséquent, ce n'est qu'en position externe que la nappe du Lebendun chevauche directement la nappe d'Antigorio. Abstract Magmatic bodies are important markers in paleo-geographic or geodynamic reconstructions of orogenic cycles, even more so in the case of polycyclic events where many of the other markers have been overwritten or destroyed. Plutons are relatively easy to date and their geochemical properties help constrain the tectonic context in which they were emplaced. This study focuses on the pre-mesozoic basement in the Sambuco and Maggia lower Penninic nappes located in the central Lepontine domain of the Alps. A number of magmatic events have been identified in the Sambuco basement. These events were dated using LA-ICPMS U/Pb on zircon grains. The mafic calc-alkaline banded Scheggia suite is dated as lower Cambrian, 540-530 Ma. The Al-rich Sasso-Nero lenticular gneiss is 480-470 Ma old (similarly to many older orfhogneisses of the Alpine basement) and contains 630-610 Ma old pan-African inherited zircons that illustrate the Gondwanian origin of these terranes.The calc-alkaline Matorello pluton is dated as 310-300 Ma whereas the lamprophyric bodies it contains are of 300 Ma. The Cocco granodiorite and the Ruscada leucogranite both intrude the basement of the adjacent Maggia nappe and are of similar ages to the Matorello. The ages as well as the geochemical similarities between the Cocco, Rucada and Matorello plutons suggest their paleo-geographic proximity at the Permian-Carboniferous boundary. However, these nappes are currently considered as belonging to two different Mesozoic paleo-geographic domains. Indeed, the Sambuco is considered as Helvetic whereas the Maggia is said to be Briançonnais, both separated by an oceanic basin. If this is the case, then it is essential that nostrike-slip movement has misaligned both continental margins since these coincide perfectly now that the oceanic domain closed. The Matorello pluton was originally a tabular intrusion, built up by the accumulation of multiple, several meter-thick, subhorizontal sheet-like injections of magma. Depending on their emplacement rate, the successive magma injections either solidified rapidly with sharp and rather well-defined boundaries (like the composite sills) or mingled with previous injections generating a thick molten layer up to several tens to hundred meters thick, like in the main granodioritic facies. These coalesced injections are hardly distinguishable, however subtle contrasts in granulometry, mineral modal proportions or mineral sorting (cross-bedded biotite-rich schlieren), as well as erosional features and/or crystal entrapment along contact surfaces allow to distinguish between the different injections. Two exceptional meter-thick layers display sinuous boundaries with the host granodiorite and consist of a densely packed accumulation of mafic enclaves in a granodioritic matrix. Gravitational sorting of the enclaves with load cast features at the base of the layers and sinuous biotite schlieren point to injection of low viscosity turbulent composite magma flows in the still largely molten granodiorite host. The hybrid nature of these rocks implies the existence of á periodically replenished and differentiated underlying magma chamber. Magmas are mafic liquids derived from the mantle and anatectic liquids of crustal origin, as shown by the (87Sr/86Sr), and epsilon Nd values (0.704-0.709 and -2.1 to -4.7 respectively. These data show that the crustal contribution is important, as confirmed by the Pb isotopes. The hybridisation processes seem to have occurred in the lower crust in magma chambers underlying the Matorello laccolith. The paleo-gravity markers in the Matorello help understand the architecture of the Sambuco nappe. Isoclinal folds with a vertical axial plane can be seen at the contact between dioritic and granodioritic facies. The antiform structure of which the Matorello is the heart is in fact a syncline. This places it in the inverse flanc of the large recumbent fold that constitutes the Sambuco nappe. The gneiss blocs found in the summital wildflysh cover of the Antigorio nappe have been linked to the Matorello pluton. This means that the front of the Sambuco nappe already overlapped the Antigorio basin when it closed. This implies that the Lebendun nappe can only overlap the Antigorio nappe in it's external position. Résumé grand public La chaîne alpine est la conséquence de la collision tertiaire entre deux masses continentales, l'Europe au nord et la péninsule apulienne africaine au sud, originellement séparées par l'océan mésozoïque téthysien. Cette collision a fermé un espace large de plusieurs centaines de km avec pour résultat l'écaillage de la croûte terrestre en unités tectoniques de dimensions variables, qui se sont empilées, imbriquées, éventuellement replissées en nappes de géométrie complexe. Cet amoncellement de 40 km d'épaisseur a vu sa température et sa pression lithostatique internes augmenter jusqu'à des valeurs de l'ordre de 680 °C et 6000 bars, induisant une recristallisation métamorphique des roches. L'un des objectifs de la géologie alpine est de reconstituer la géographie de la région aux temps mésozoïques de l'océan téthysien, en d'autres termes, de replacer chacune des unités tectoniques identifiées au sein de l'empilement alpin dans sa position originelle. Le défi est de taille et peut être comparé à celui de la reconstitution d'un vaste puzzle, dont certaines pièces seraient endommagées au niveau de leur contour ou leurs couleurs (métamorphisme), dissimulées par d'autres (enfouissement), voire tombées de la table de jeu (subduction, échappement latéral). Plusieurs approches ont été mises en oeuvre au cours du siècle écoulé. On citera en particulier la stratigraphie, la tectonique et le paléomagnétisme. Dans ce travail, nous avons essentiellement utilisé des techniques de datation isotopique absolue des roches (U/Pb sur zircon) qui, sur la base des connaissances acquises par l'ensemble des autres disciplines géologiques, nous ont permis de mieux contraindre ta paléogéographie mésozoïque du domaine «pennique inférieur » des Alpes centrales lépontines. Et au-delà? Nous savons tous que la disposition des continents à la surface de la Terre évolue constamment. Il est donc tentant d'essayer de remonter plus loin encore dans le temps et de reconstituer la physionomie de la marge sud européenne, tout au moins certains éléments de son histoire, au cours de l'ère paléozoïque. Les traces de ces événements très anciens sont naturellement ténues et dans ce contexte, les techniques de datation mentionnées ci-dessus deviennent les outils les plus performants. Ainsi, des datations u/Pb sur zircon nous ont permis de recenser plusieurs intrusions magmatiques, attribuées à quatre événements orogéniques anté-alpins. Des âges néoprotérozoïques (630-610 millions d'années ou Ma), cambrien inférieur (540-530 Ma), ordovicien inférieur (480-470 Ma) et carbonifère supérieur-permien inférieur (310-285 Ma) ont été obtenus dans le socle de la nappe de Sambuco. Des âges similaires à 300 Ma ont été obtenus dans la nappe voisine de la Maggia, qui permettent de relier ces deux unités. Aujourd'hui côte à côte, ces deux nappes devaient également se trouver proches l'une de l'autre il y a 300 Ma, lors de l'extension post-varisque. Les structures magmatiques spectaculaires préservées dans le pluton du Matorello (300 Ma) contraignent la géométrie actuelle de la nappe de Sambuco dans laquelle l'intrusion s'est mise en place. La forme originelle du pluton, aujourd'hui retourné et replissé plusieurs fois, s'avère être tabulaire, faite d'intrusions de faible épaisseur (1-300 m) s'étalant en forme de disque (30m à 2 km de diamètre). Les injections successives de magma se sont accumulées sous un toit dioritique précoce; elles sont issues, par le refais de fractures, d'une chambre magmatique plus profonde, périodiquement réalimentée par des magmas calco-alcalins d'origine mantellique contaminés parla croûte continentale profonde (εNd = -2.1 à -4.7). Des accumulations d'enclaves magmatiques arrondies et granoclassées dans des paléo-chenaux à fond érosif témoignent de conditions de mise en place hydrodynamiques à haute énergie. Ces enclaves sont emmenées de la chambre magmatique sous-jacente à la faveur d'épisodes de fracturation hydraulique liés à l'injection de magmas matelliques chauds dans des liquides différenciés riches en eau. Cette hypothèse est étayée par l'existence de filons composites. Une paléohorizontale a pu être déduite au sein du pluton, indiquant que cette partie de la nappe de Sambuco est verticalisée et isoclinalement replissée par la déformation alpine. Finalement, des blocs érodés du socle Sambuco ont été retrouvés dans le wildflysch sommital de la couverture sédimentaire mésozoïque de la nappe d'Antigorio sous-jacente. Ceci suggère que les blocs ont été fournis parle front de la nappe de Sambuco en train de chevaucher sur la nappe d'Antigorio au moment de la fermeture du bassin sédimentaire de cette dernière.

Indications for cardiovascular magnetic resonance in children with congenital and acquired heart disease: an expert consensus paper of the Imaging Working Group of the AEPC and the Cardiovascular Magnetic Resonance Section of the EACVI.

This article provides expert opinion on the use of cardiovascular magnetic resonance (CMR) in young patients with congenital heart disease (CHD) and in specific clinical situations. As peculiar challenges apply to imaging children, paediatric aspects are repeatedly discussed. The first section of the paper addresses settings and techniques, including the basic sequences used in paediatric CMR, safety, and sedation. In the second section, the indication, application, and clinical relevance of CMR in the most frequent CHD are discussed in detail. In the current era of multimodality imaging, the strengths of CMR are compared with other imaging modalities. At the end of each chapter, a brief summary with expert consensus key points is provided. The recommendations provided are strongly clinically oriented. The paper addresses not only imagers performing CMR, but also clinical cardiologists who want to know which information can be obtained by CMR and how to integrate it in clinical decision-making.

Predictive ability of heel quantitative ultrasound for incident fractures: an individual-level meta-analysis.

UNLABELLED: The relationship between bone quantitative ultrasound (QUS) and fracture risk was estimated in an individual level data meta-analysis of 9 prospective studies of 46,124 individuals and 3018 incident fractures. Low QUS is associated with an increase in fracture risk, including hip fracture. The association with osteoporotic fracture decreases with time. INTRODUCTION: The aim of this meta-analysis was to investigate the association between parameters of QUS and risk of fracture. METHODS: In an individual-level analysis, we studied participants in nine prospective cohorts from Asia, Europe and North America. Heel broadband ultrasonic attenuation (BUA dB/MHz) and speed of sound (SOS m/s) were measured at baseline. Fractures during follow-up were collected by self-report and in some cohorts confirmed by radiography. An extension of Poisson regression was used to examine the gradient of risk (GR, hazard ratio per 1 SD decrease) between QUS and fracture risk adjusted for age and time since baseline in each cohort. Interactions between QUS and age and time since baseline were explored. RESULTS: Baseline measurements were available in 46,124 men and women, mean age 70 years (range 20-100). Three thousand and eighteen osteoporotic fractures (787 hip fractures) occurred during follow-up of 214,000 person-years. The summary GR for osteoporotic fracture was similar for both BUA (1.45, 95 % confidence intervals (CI) 1.40-1.51) and SOS (1.42, 95 % CI 1.36-1.47). For hip fracture, the respective GRs were 1.69 (95 % CI, 1.56-1.82) and 1.60 (95 % CI, 1.48-1.72). However, the GR was significantly higher for both fracture outcomes at lower baseline BUA and SOS (p < 0.001). The predictive value of QUS was the same for men and women and for all ages (p > 0.20), but the predictive value of both BUA and SOS for osteoporotic fracture decreased with time (p = 0.018 and p = 0.010, respectively). For example, the GR of BUA for osteoporotic fracture, adjusted for age, was 1.51 (95 % CI 1.42-1.61) at 1 year after baseline, but at 5 years, it was 1.36 (95 % CI 1.27-1.46). CONCLUSIONS: Our results confirm that quantitative ultrasound is an independent predictor of fracture for men and women particularly at low QUS values.

Neurology and psychiatry: waking up to opportunities of sleep. : State of the art and clinical/research priorities for the next decade.

In recent years, evidence has emerged for a bidirectional relationship between sleep and neurological and psychiatric disorders. First, sleep-wake disorders (SWDs) are very common and may be the first/main manifestation of underlying neurological and psychiatric disorders. Secondly, SWDs may represent an independent risk factor for neuropsychiatric morbidities. Thirdly, sleep-wake function (SWF) may influence the course and outcome of neurological and psychiatric disorders. This review summarizes the most important research and clinical findings in the fields of neuropsychiatric sleep and circadian research and medicine, and discusses the promise they bear for the next decade. The findings herein summarize discussions conducted in a workshop with 26 European experts in these fields, and formulate specific future priorities for clinical practice and translational research. More generally, the conclusion emerging from this workshop is the recognition of a tremendous opportunity offered by our knowledge of SWF and SWDs that has unfortunately not yet entered as an important key factor in clinical practice, particularly in Europe. Strengthening pre-graduate and postgraduate teaching, creating academic multidisciplinary sleep-wake centres and simplifying diagnostic approaches of SWDs coupled with targeted treatment strategies yield enormous clinical benefits for these diseases.

Early Modern Persian, Urdu, and English Historiography and the Imagination of Islamic India under British Rule

This paper analyses the early modern transformations of South Asian literary cultures through the production of historiography in Persian, English, and Urdu. In the 18th-19th centuries, South Asian communities experienced and participated in a major restructuring of the languages of the subcontinent. Urdu and English were institutionalized as governmental languages and utilized in new literary productions as Persian was gradually marginalized from the centre of literary and governmental polities. Three interrelated colonial policies reshaped the historical consciousness of South Asia and Britain: the production of new Persian histories commissioned under British patronage, the initiation of Urdu historiography through the translation of Persian and English histories, and the construction of the British history of India written in English. This article explores the historical and social dynamics of these events and situates the origins and evolution of the colonial historiographical project. Major works discussed are the Tārīkh-i Bangālah of Salīm Allāh Munshī (fl. 1763), James Mill's (1773-1836) The History of British India first published in 1817, Mīr Sher ʿAlī Afsos' the Ārāʾish-i mahfil, as well as the production of original Urdu histories such as Muḥammad Zakāʾ-Allāh's (1832-1910) the Tārīkh-i Hindustān.

Courts and Courtly Cultures in Early Modern Italy and Europe: Models and Languages

This volume deals with the forms of propaganda and self-representation, through words and images, during the rise of the 'civiltà delle corti' and through processes typical of the time, such as confrontation, adaptation, competition and rivalry. This period, which marked the passage of Italian and European culture from the Middle Ages to the Renaissance, is fundamental in the development of Modern Europe, and it lasted up to the XVIII century and beyond. At the heart of many matters debated here lies the relationship between culture and politics. The formation of a 'Lombard identity', central to the Sinergia project which was the frame of the whole research and its conferences, is closely linked to this broad general context. It places the so called 'questione milanese' - above the traditional hierarchies 'Toscana oriented' - at the centre of many questions regarding Northern Italy as a whole, starting from the dissolution of the Medieval communes, through to the rise of the signorie, from the end of the XIII century and the beginning of the XIV century up to the early XVI century.

Fingermark age determinations: legal considerations, review of the literature and practical propositions

The question of the age of fingermarks is often raised in investigations and trials when suspects admit that they have left their fingermarks at a crime scene but allege that the contact occurred at a different time than the crime and for legal reasons. In the first part of this review article, examples from American appellate court cases will be used to demonstrate that there is a lack of consensus among American courts regarding the admissibility and weight of testimony from expert witnesses who provide opinions about the age of fingermarks. Of course, these issues are not only encountered in America but have also been reported elsewhere, for example in Europe. The disparity in the way fingermark dating cases were managed in these examples is probably due to the fact that no methodology has been validated and accepted by the forensic science community so far. The second part of this review article summarizes the studies reported on fingermark dating in the literature and highlights the fact that most proposed methodologies still suffer from limitations preventing their use in practice. Nevertheless, several approaches based on the evolution of aging parameters detected in fingermark residue over time appear to show promise for the fingermark dating field. Based on these approaches, the definition of a formal methodological framework for fingermark dating cases is proposed in order to produce relevant temporal information. This framework identifies which type of information could and should be obtained about fingermark aging and what developments are still required to scientifically address dating issues.
