Resumen

Purpose The purpose of this paper is to identify the impact of career plateau (hierarchical and job-content plateau) on internal employability, and to investigate psychological contract breach as a moderator on the relationship between career plateau (hierarchical and job-content plateau) and internal employability. Design/methodology/approach Data were collected by distributing paper-based questionnaires to 521 workers in private banking sectors in Taiwan. Hierarchical regression analysis was used to examine the results of the relationships. Findings The results supported the idea that career plateau (hierarchical and job-content plateaus) could be a significant antecedent of internal employability. Psychological contract breach significantly moderated the negative relationship between career plateau (hierarchical and job-content plateau) and internal employability. Specifically, the negative relationship between career plateau and internal employability will be stronger for employees who perceive a higher level of psychological contract breach. Practical implications These findings can help human resource practitioners gain a better understanding of the value of applicable approaches as an influence on a plateaued employee’s perception of internal employability, and to facilitate a positive employer–employee relationship, which could foster both a successful career for an individual and a prosperous performance for the organization that employs them. Originality/value Career plateau have been aroused variety issues in HR practice, but employability and psychological contract breach have barely been discussed with career plateau. This study empirically establishes the correlation between career plateau and internal employability as well as shown that psychological contract breach would decrease the plateaued individual’s willingness to stay in the current organization. Thus, the career plateau may provide organizations with a helpful perspective on one’s career development. Building substantial relationships between employees and employers lead to better human capital for organizations as it deals with rapidly changes in the real world.

Resumen

Abstract Idealized numerical simulations are presented to investigate the sensitivity of the thermal plateau circulation to the plateau height, width, and the presence of a mountain ridge encompassing the plateau. The study concentrates on plateaus surrounded by land with the same surface properties so that the topography is the only source of differential heating. For low plateaus, it is found that the strength of the plateau circulation increases with the plateau height because the excess heating of the plateau increases with its height. The plateau circulation reaches its maximum strength for plateau heights similar to the mixed-layer depth over the surrounding lowlands. For even higher plateaus, the depth of the circulation decreases whereas the peak intensity exhibits little change. The plateau height also controls the temporal evolution of the plateau circulation. For low plateaus, low-level inflow is primarily found during the night because convection cells forming over the lateral slopes prevent an inward mass flux during the day. With increasing plateau height, the phases of the plateau circulation shift toward earlier times. If the plateau height exceeds the mixed-layer depth over the surrounding lowlands, inflow occurs from afternoon until the late evening. After sunset, the inflow layer tends to assume the characteristics of a density current. The convergence of the density currents propagating from each side of the plateau toward the center helps to fill the heat low formed during the day. Moreover gravity waves are triggered that propagate away from the plateau center and terminate the inflow. The propagation speed of the density currents is found to increase with the plateau height, so that their convergence occurs earlier for high plateaus than for low plateaus. For the parameter range considered in this study, the plateau width is found to have only a minor impact on the mass fluxes associated with the plateau circulation. However, the convergence of the density currents over the plateau center occurs later for a wider plateau, implying that the heat low is more persistent. Substantial changes are obtained when the plateau is surrounded by a mountain ridge. In this case, the inflow toward the plateau gets delayed because a slope wind circulation forms over the mountain ridge. Moreover, the mass fluxes toward the plateau are reduced so that the heat low that formed over the plateau during the day is filled only slowly. As a consequence, the inflow lasts throughout the night in the presence of a high mountain ridge surrounding the plateau.

Resumen

Abstract. The Manihiki Plateau is a Large Igneous Province (LIP) in the central Pacific. It was emplaced as part of the "Super-LIP" Ontong Java Nui and experienced fragmentation into three sub-plateaus, possibly during the break-up of Ontong Java Nui. The Manihiki Plateau is presumably the centerpiece of this "Super-LIP" and its investigation can therefore decipher the break-up mechanisms as well as the evolution of the plateau after its initial emplacement. By analyzing two seismic refraction/wide-angle reflection profiles crossing the two largest sub-plateaus of the Manihiki Plateau, the High Plateau and the Western Plateaus, we give new insights into their crustal structure and magmatic evolution. The High Plateau shows a crustal structure of 20 km thickness and a seismic P wave velocity distribution, which is comparable to other LIPs. The High Plateau experienced a strong secondary volcanism, which can be seen in relicts of seamount chain volcanism. The Western Plateaus on the other hand show no extensive secondary volcanism and are mainly structured by fault systems and sedimentary basins. A constant decrease in Moho depth (9–17 km) is a further indicator of crustal stretching on the Western Plateaus. Those findings lead to the conclusion, that the two sub-plateaus of the Manihiki Plateau experienced a different magmatic and tectonic history. Whereas the High Plateau experienced a secondary volcanism, the Western Plateaus underwent crustal stretching during and after the break-up of Ontong Java Nui. This indicates, that the sub-plateaus of the Manihiki Plateau play an individual part in the break-up history of Ontong Java Nui.

Resumen

Purpose The purpose of this paper is to discuss how Aster Retail (AR), UAE, handled career plateau challenge by adopting multiple strategies and earning employee commitment and motivation for business growth. Design/methodology/approach The organization addressed two types of plateaus – structural and content by creating both vertical and lateral opportunities/options for employees, and supporting them with resources to build required capabilities, and managing their career aspirations. The strategies also helped AR to remain true to the organization’s philosophy, “We will treat you well.” Findings The study enunciates how HR initiatives can add value by converting the negative phenomenon of plateau, into an opportunity for employees to grow. Originality/value The study has three contributions: How in a retail organization with strong promoter principles and values, both structural and content plateau are addressed, and linked with business strategies? The study sheds light on how organizational and HR support for career management addresses employee plateau, particularly for solid citizens. makes the employees feel “not plateaued” at all; and in the long run, why and how HR managers should focus more on proactively addressing content plateau than structural plateau.

Resumen

A vertical magnifier before one eye causes the induced effect: an apparent rotation of frontal surfaces toward that eye. The rotation required to restore apparent frontoparallelism grows linearly up to ∼4% magnification, but plateaus at 8%. We examined the cause of the plateau. Horizontal disparities (quantified by horizontal size ratios, HSRs) are ambiguous indicators of surface slant. Various retinal and nonretinal signals can allow veridical slant estimation from HSR, sensed eye position, vertical disparities (vertical size ratios, VSRs), and monocular cues. Vertical or horizontal magnification of one eye's image alters the natural relationships among HSR, VSR, eye position, and monocular cues. We argue that the induced-effect plateau is caused by conflicts between these means of estimating slant. A plateau is not observed in the geometric effect because some of the conflicts do not occur with horizontal magnification. Two experiments were designed to test this hypothesis. When strong monocular cues were present, plateaux occurred at ∼8% magnification in the induced, but not the geometric effect. When monocular slant cues were made useless, induced-effect plateaux were abolished. Even with strong monocular cues present, plateaux in the induced effect were eliminated when eye position was consistent with the vertical magnification in the retinal images. The smaller range of the induced effect can only be understood from consideration of all the signals involved in slant estimation.

Resumen

Purpose. Morphological differences in the knee joints of females and males have been reported in a previous study. These differences have realized the need of developing a gender-specific prosthesis. However, anatomical studies on gender-based differences in the proximal tibial plateau’s sagittal curvature have rarely been conducted. Therefore, this study is aimed at evaluating the geometry of the sagittal curvature of the proximal tibial plateau in the Korean population. Methods. Three-dimensional data for the sagittal curvature of the tibial plateau morphology from 1976 patients (i.e., 299 male and 1677 female) were assessed using magnetic resonance imaging. The sagittal profiles of the tibial plateaus were also evaluated. The independent t -test and paired t -test were used for statistical analysis. Results. The proximal tibia had concave and convex surfaces in the medial and lateral plateaus, respectively, for both genders. In addition, the medial diameter of the tibial plateau was significantly greater than the lateral diameter for both genders. Gender-based difference was not found in the medial diameter of the tibial plateau but was observed in the lateral diameter. Conclusion. These results may provide guidelines for a suitable knee implant design for the Korean patients. The incorporation of this shape information in the medial and lateral sides in the prosthetics for a total knee arthroplasty and a lateral unicompartmental knee arthroplasty can improve knee range motion.

Resumen

AbstractThe tuning of plateaus in glacial and deglacial planktic radiocarbon records to pertinent structures in the atmospheric14C record of Lake Suigetsu results in both a record of surface water reservoir ages and a centennial-scale absolute age model. However, the atmospheric origin of planktic14C plateaus may be questioned. Alternatively, plateaus may result from short pulses of increased hemipelagic sediment deposition, which challenges the technique of14C plateau tuning. To test the two rationales for the interval 23–12 cal ka, we calculated hypothetical sedimentation rates for all14C plateaus identified in five Atlantic sediment cores assuming sediment pulses that either span 10, 100, 200, or 300 yr each. These rates were compared to rates derived by14C plateau tuning that assumes an atmospheric origin of the plateaus. In each plateau suite, our hypothetical sedimentation rates result in at least one or two cases in extreme values that exceed the rates reported for short-lasting pulses of sediment deposition in contourites by a factor of 50 and therefore appear unrealistic. Moreover, they result in entire suites of plateau structures that incidentally appear closely aligned to the pattern of atmospheric14C plateau suites rather than to any pulses of climate-controlled sediment discharge.

Resumen

The Western Ghats represents a small part of the Deccan Traps continental flood basalt province that erupted about 65 million years ago. It is an area of outstanding scenic beauty and has attracted the attention of geologists, naturalists and geomorphologists for over a century. One of the unique habitats in the Western Ghats are the rocky plateaus. Previous studies have covered plant species composition, geological and geomorphological status of the rocky plateaus. An analytical study of microhabitats and associated therophytes of four rocky plateau sites was conducted. The study sites were Durgawadi Plateau, Naneghat Plateau which are basalt outcrops and Zenda plateau and Amba Plateau, which are laterite outcrops on the escarpment of the northern Western Ghats. The results revealed a correlation between basalt and lateritic rock outcrops as well as ephemeral plant elements. All four outcrops are similar in their nutrient status but the microhabitats of these plateaus are extremely different from each other.

Resumen

Long-lasting, dendritic, Ca2+-dependent action potentials (plateaus) were investigated in layer 5 pyramidal neurons from rat neocortical slices visualized by infrared-differential interference contrast microscopy to understand the role of dendritic Ca2+ spikes in the integration of synaptic input. Focal glutamate iontophoresis on visualized dendrites caused soma firing rate to increase linearly with iontophoretic current until dendritic Ca2+ responses caused a jump in firing rate. Increases in iontophoretic current caused no further increase in somatic firing rate. This limitation of firing rate resulted from the inability of increased glutamate to change evoked plateau amplitude. Similar nonlinear patterns of soma firing were evoked by focal iontophoresis on the distal apical, oblique, and basal dendrites, whereas iontophoresis on the soma and proximal apical dendrite only evoked a linear increase in firing rate as a function of iontophoretic current without plateaus. Plateau amplitude recorded in the soma decreased as the site of iontophoresis was moved farther from the soma, consistent with decremental propagation of the plateau to the soma. Currents arriving at the soma summed if plateaus were evoked on separate dendrites or if subthreshold responses were evoked from sites on the same dendrite. If plateaus were evoked at two sites on the same dendrite, only the proximal plateau was seen at the soma. Just-subthreshold depolarizations at two sites on the same dendrite could sum to evoke a plateau at the proximal site. We conclude that the plateaus prevent current from ligand-gated channels distal to the plateau-generating region from reaching the soma and directly influencing firing rate. The implications of plateau properties for synaptic integration are discussed.

Resumen

AbstractPlateau icefields occur commonly in glacierized areas and not uncommonly in glaciated mountains. We report on a glacierized area of plateaux and valleys centred round the highest peak Jiehkkevárri (1833 m) in the maritime Lyngen Alps, North Norway. Some valley glaciers are fed by steep, narrow plateau glacier outlets and/or ice avalanching from the plateaux over precipitous cliffs. Plateaux must therefore be considered as “contributing areas”, if they supply ice to valley systems below. Equilibrium line altitudes (ELAs) are calculated for the valley glaciers during the Little Ice Age (LIA), accounting for both input and no input of ice from plateaux above. The results show that ELAs may be at significantly higher altitudes when plateau/x are contributing ice mass. The response of plateau glaciers to climate amelioration since the end of the LIA is somewhat different to that of valley glaciers, which appear to be retreating markedly. These findings have significant implications for the interpretation of moraine systems, glacier dynamics, the construction and reconstruction of present and former ELAs, and palaeoclimates in glacierized and glaciated mountain plateau areas.

Resumen

The structural link that ties the formation of the central Andean plateau to the evolution of the Andean fold-thrust belt is formation and propagation of basement megathrusts. Balanced cross-sections through a regional west-vergent thrust system in the hinterland of the eastward-verging Andean fold-thrust belt suggest that the Altiplano basin is a crustal-scale, piggy-back basin created as a basement megathrust propagated up and over a half-crustal scale ramp located on the eastern edge of the Altiplano. The backthrust belt, detached above the basement thrust sheet, acted as a crustal-scale, passive-roof duplex building taper after the megathrust overextended the system eastward. Pervasive shortening and vertical elongation seen at the outcrop and regional scales supports the development of the backthrust belt as a taper-building mechanism. The interrelationship of the backthrust belt, basement megathrust, and Andean plateau is shown in a sequential, kinematic model based on balanced cross sections from the volcanic arc to the foreland. The model links the formation of the plateau to east- and west-verging portions of the Andean fold-thrust belt through the eastward propagation of two large basement megathrusts. The megathrusts can explain topographic and structural steps in the Andean fold-thrust belt and accommodate a minimum of 300-330 km of shortening which matches shortening estimates in the tightly folded and faulted cover rocks. To a first approximation, the eastern margin of the central Andean plateau (defined by the 3 km topographic contour) is contiguous with the leading edge of the upper basement megathrust. The relationship between the basement highs and the physiographic boundaries of the Andean plateau suggests that extensive megathrust sheets (involving strong rocks such as crystalline basement or quartzite) play an important role in the formation of the central Andean plateau. Combining the history of foreland basin migration with palinspastically restored regional cross sections across the Bolivian Andes between 18°-20°S argues for an eastward migrating fold-thrust belt/foreland basin system since the late Cretaceous. The longer time span for the Andean orogeny implies greater shortening amounts, a decrease in shortening rates with time and a high (3-4 km) Andean plateau by 20 Ma.

Resumen

Le plateau de Demerara est un plateau marginal situé le long de la marge de la Guyane française et du Surinam. Grâce aux données récentes acquises lors de la campagne IGUANES, avec des données géophysiques et des carottes sédimentaires, certaines structures sédimentaires illustrent une forte influence du courant sur la construction récente de cette marge.Les géométries sédimentaires suggèrent la présence d'un Système de Dépôt contouritique (CDS) sur ce plateau. Le fond marin est marqué par la présence de structures longitudinales formées par l'activité actuelle: « giant flute casts » ou queues de comètes et des « longitudinal waves ». Sur la base de l'analyse des données chirp et des carottes, la présence de processus contouritiques a été identifiée sur les plateaux marginaux intermédiaires et inférieurs. Cette contourite est probablement induite par la circulation de la NADW. Des structures sédimentaires sont présentes et enregistrées après cet événement : des « comet marks » et des « longitudinal waves ».Le contourite sur ce plateau est constitué de sédiments riches en illustrant le vannage induit par les courants de fond. L'étude des carottes sédimentaires associées à un cadre chrono-stratigraphique permet d'identifier les caractéristiques sédimentaires en fonction de l'intensité du courant. La glauconite, minéral authigénique, est utilisé comme un nouvel outil qui, couplé à des analyses granulométriques et de faciès, permet d’enregistrer les variations du vannage. Sur le plateau de Demerara, la sédimentation indiquent des taux d'accumulation sédimentaire faibles et des courants de fond intenses pendant les périodes glaciaires.La présence de contourites le long du plateau de Demerara et le long d'autres plateaux marginaux montre l'impact fort de tels reliefs bathymétriques sur la circulation océanique
The Demerara Plateau is a marginal plateau located along the French Guyana and Surinam margin. Thanks to the recent data acquired during the IGUANES cruise, with geophysical data and sedimentary cores, some sedimentary structures illustrate a strong current influence on the recent building of this margin. The sedimentary geometries suggest the presence of a Contourite Depositional System (CDS). The seafloor is marked by the presence of longitudinal structures formed by the current activity: giant flute clasts or comet marks, and longitudinal waves. Based on the chirp data analysis and on cores, some sedimentary domains are identified on the Demerara marginal plateau. The intermediate and the lower marginal plateaus are affected by contouritic process with two moats and a mounded elongated drift. This contourite is likely induced by the NADW circulation. The contourite on this plateau is made of glauconitic rich sediments inside the moat showing the winnowing effect induced by the bottom currents. The detailed study of sedimentary cores associated with a chronostratigraphic framework allows identifying the sedimentation features depending on current intensity through time. The glaucony authigenic mineral is used as a main proxy, coupled with grain-size and facies analyses, for inferring the degree of winnowing at the sediment-water interface. On the Demerara plateau, the sedimentation suggests low sediment accumulation rates and quite energetic bottom currents during ice periods.The presence of contourites along the Demerara Plateau and along other marginal plateaus shows the strong impact of such deep-sea marginal bathymetric reliefs on the oceanic circulation

Resumen

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Earth, Atmospheric, and Planetary Sciences, 2008.
Includes bibliographical references.
This thesis addresses processes associated with the uplift, deformation, and erosion of orogenic plateaus. The timing and mechanisms of uplift of the Tibetan Plateau and the Altiplano are the subject of ongoing debate. Central issues include the strength of the lower crust and the role of lower crustal flow, the relative importance of continuous deformation versus block deformation, and the possibility of lithospheric delamination. The goal of this thesis is to further explore several of these issues using a combination of numerical modeling, field observations, and thermochronology. I investigate controls on the large-scale evolution of the Tibetan Plateau and the Altiplano using a new quasithree-dimensional viscous flow model that allows for both the development of a weak lower crust and lateral and temporal viscosity variations. Modeling motivated by the Tibetan Plateau shows that lateral variations in crustal strength can have a significant effect on surface velocities throughout the plateau, as well as on the location, shape, and slope of plateau margins and the overall plateau morphology. Model results suggest that crustal strength heterogeneities may be responsible for a number of seemingly unrelated aspects of Tibetan Plateau morphology and deformation. Modeling motivated by the Altiplano explores the relationship between subduction angle, the strength of the lower crust, crustal thickening, and surface shortening in the Central Andes. Model results illustrate that lower crustal flow above regions of steep-slab subduction can redistribute material along strike and can explain discrepancies between surface shortening and crustal thickness in the northern and southern Altiplano. I address the distribution of Middle Cenozoic deformation on the eastern margin of the Tibetan Plateau by using field observations and thermochronology to document an episode of extension and constrain its timing to the Oligocene. Finally, I examine the response of a major river system to flow over an abrupt plateau margin by using topographic data, cosmogenic nuclide dating, and numerical modeling to describe the incision history of the Colorado River into the southwestern Colorado Plateau.

Resumen

Les marges transformantes, formées par le coulissage des plaques lors des premières étapes de l’ouverture océanique, ont été peu étudiées relativement aux marges divergentes. La marge de Côte d’Ivoire-Ghana fait figure d’exemple-type, et l’absence d’inventaire exhaustif ainsi que le peu d’étude de marges transformantes conjuguées entraîne une méconnaissance de la véritable diversité de ce type de marge. Deux approches ont été abordées dans ce mémoire. La première a consisté à les inventorier dans le monde à partir d’une méthodologie simple. Elles ont ensuite été comparées (physiographie et structure). La deuxième s’est concentrée sur l’étude tectono-sédimentaire des marges transformantes conjuguées des plateaux de Demerara et de Guinée. L’inventaire des marges transformantes a montré que les marges transformantes représentent 30% des marges passives. Leur distribution au sein de domaines océaniques ouverts de façon très oblique ou à l’intersection entre grands domaines reflète des conditions d’initiation spécifiques. 30% des marges transformantes se trouvent notamment en bordure d’un plateau marginal ; un type de bassin à l’histoire double nouvellement défini, qui semble associé à un fort amincissement crustal. Par ailleurs, on montre que les marges transformantes présentent des architectures diverses et sont souvent segmentées. L’étude des plateaux marginaux de Demerara et Guinée a permis de montrer qu’elles se mettent en place au niveau d’un domaine pré-aminci, sans doute guidées par des structures préexistantes. La nature du soubassement des plateaux est discutée : éventails sédimentaires ou volcaniques type SDR. La formation et l’évolution des marges transformantes en bordure des deux plateaux a été accompagnée de déformations intenses à l’approche des frontière océan-continents ainsi que de plusieurs épisodes de soulèvement et subsidence successifs de la bordure transformante, dont les origines et mécanismes sont discutés
Transform margins form by transform motion between plates during early stages of oceanic spreading. They have been poorly studied in comparison with divergent margins, at least for the last 15 years. The Côte d’Ivoire-Ghana margin represents the best known example of a transform margin and is often considered as a model. However, the lack of a global complete inventory of such margins may lead to underestimate their diversity. Two approaches have been developed in this work. The first one consisted in a compiling world transform margins using a systematic and simple methodology. Those margins have then been compared (physiography, structure). In a second approach we analysed the tectono-sedimentary evolution of the Demerara and Guinea conjugated transform-derived plateaus. The worldwide review of transform margins shows that those represent 30% of the existing passive margins. Their distribution inside very oblique oceanic domains, and at the intersection between oceanic domains of contrasted ages, reflects specific initiation conditions. 30% of those transform margins locate on the edge of marginal plateaus —newly defined type of basins— that seem to be associated with important crustal thinning. Furthermore, this inventory shows that transform margins display a great variety of architectures. The Demerara and Guinea marginal plateaus are bounded by transform margins that occur on an already thinned crust, probably along a preexisting structure. The nature of these plateaus basement is discussed: sedimentary or volcanic SDRs fan-shaped units? During the Equatorial Atlantic opening, the formation and evolution of Demerara and Guinea transform margins were accompanied by intense deformations close to the continent-ocean boundary and by several successive uplift and subsidence phases along the plateaus borders. Their origin and mechanisms are discussed

Resumen

The Qilian Mountains are one of the most actively uplifting regions of the Tibetan Plateau and may provide a type example for the early evolution of its older regions. The mountains form a 300 km wide, NW – SE trending fold-thrust belt which extends 1000 km along the northeast margin of the Plateau and over-thrust the Hexi Corridor to the northeast and the Qaidam Basin to the southwest. An early-mid Palaeozoic orogenic suture belt, composed of faulted terranes of Late Proterozoic to early-mid Palaeozoic meta-sedimentary and meta-volcanic strata, is exposed in the Qilian Mountains and has been previously suggested to be reactivated by Late Cenozoic deformation. NE-directed crustal shortening, associated with the far-field effects of the Indo-Asian collision, has been active in the Qilian Mountains since the early-mid Miocene. It is characterised by the uplift of high mountain ranges along crustal scale thrust faults which splay south-eastwards from the sinistral-slip, north-northeast trending Altyn Tagh Fault and are postulated to connect along a shallow-dipping decollement in the midlower crust. Initiation of uplift in the Qilian Mountains was associated with a considerable decrease in the slip rate along the eastern end of the Altyn Tagh Fault and coincides with a plateau-wide reorganisation of deformation. This project presents new field mapping and remote sensing analysis and integrates this with existing geophysical data to i) understand and constrain the tectonic evolution of the northeast corner of the Qilian Mountains and the northwest corner of the Hexi Corridor, ii) examine the structural and lithological control of the Palaeozoic accretionary crust over Late Cenozoic deformation within the mountain ranges, and iii) establish the spatial and temporal extent of different styles of deformation within the northeastern Qilian Mountains.

Resumen

Il problema di Plateau, che prende il nome dal fisico belga Joseph Plateau, consiste nella ricerca della superficie che, tra tutte quelle aventi un determinato bordo, abbia area minima. Già nel 1744 Eulero si era proposto di cercare la superficie di area minima avente come bordo due circonferenze poste su piani paralleli i cui centri appartengono ad una retta ortogonale ad entrambi. Tale superficie è la catenoide. Molti matematici cercarono soluzioni del problema di Plateau: Lagrange nel 1762, introdusse il termine superfici minime e determinò l'equazione che doveva essere soddisfatta dalle superfici di area minima, la cosiddetta equazione di Eulero-Lagrange; Mesnieur nel 1776 scoprì un'altra superficie minima, l'elicoide e dimostrò che le superfici di area minima hanno curvatura media nulla in ogni punto. Monge nel 1783 dimostrò che, nel caso di superfici esprimibili come grafico di funzioni differenziabili, superfici con curvatura media nulla e superfici di area minima coincidono. Solo nei primi anni del '900 si ebbero soluzioni generali del problema di Plateau, grazie ai lavori di Tibor Radò e Jesse Douglas. Quest'ultimo venne premiato nel 1936 con la medaglia Fields.

Resumen

The glacial history of the Tibetan Plateau has long been a contentious topic with widely different reconstructions. For Tanggula Shan, an extensive mountain range on the central Tibetan Plateau, multiple glacial reconstruc- tions and studies on the glacial chronology have been presented. However, the glacial geomorphological record has been sparse resulting in insufficient data to fully infer the area’s palaeoglaciology. Focussing on four landform categories, glacial valleys, marginal moraines, hummocky terrain, and glacial lineations; a glacial geomorphological map was produced, using Landsat 7 ETM+ satellite imagery, SRTM digital elevation model, and Google Earth. This map, together with GIS analyses and available cosmogenic exposure and electron spin reso- nance ages from the study area, was used to investigate the extent of former glaciations. Cosmogenic exposure and electron spin resonance ages range from 18.4 ± 1.6 to 203.4 ± 33.2 ka (recalculated using the CRONUS calculator). The extent of the glacial footprint is restricted to the high mountain areas, and is similar in extent to earlier glacial reconstructions. This glacial footprint can tentatively be explained by a monsoonal influence in the southeast, with the influence diminishing to the northwest. Alternatively, the precipitation gradient might have resulted in cold-based ice in the west and warm-based ice in the east. These variations in ice regime could have left fewer traces of glaciation in the west, than in the east. There is no evidence supporting an ice sheet covering the entire Tibetan Plateau. Rather, the available data support a smaller ice field in the high mountain areas, with a maximum extent well before the Last Glacial Maximum.

Resumen

Institution séculaire, l'hôpital sous la pression des découvertes médicales et de l'élévation du niveau de vie de la population française s'est ouvert au milieu du vingtième siècle à toutes les classes de la société. De la loi du 21 décembre 1941 date la naissance juridique d'une nouvelle institution hospitalière désormais orientée principalement d'abord, puis exclusivement ensuite (loi du 31 décembre 1970), vers les soins. L'hôpital, institution charitable, devient une "entreprise" de soins bouleversant totalement son organisation et sa gestion. L'hôpital s'adapte aux besoins de la population, aux exigences de la science médicale et aux nécessités d'une gestion économe et participative. Cette évolution tend a séparer complètement voire à rendre financièrement antagoniste le rôle hôtelier originel et le rôle tout récent de prestataire de soins à haute valeur ajoutée. L'hôpital "hôtel" laisse place à l'hôpital "plateau technique". Cependant, pendant de nombreuses années ces deux activités coexisteront entraînant les adaptations juridiques idoines
Under the pressure of medical discoveries and French people high standard of living, hospitals which are an age-long institution opened to all classes of society in the middle of the twentieth century. The legal birth of a new hospital institution dates from 1941 december 21st Law, it was first principally and now exclusively directed towards medical care. Hospitals, charity institution, become a care undertaking upsetting totally its organisation and management. Hospitals fit to population needs, medical science requirements and economical and participative management necessities. This evolution leads to keep completely apart and even financially opposed the original lodging part and the new highly specialized medical care part. "hotel" hospitals let place to medico-technical department. Meanwhile, for many years, these both activities will live together, involving juridical suitable accommodations
