Social Investment Policies in Times of Permanent Austerity

The objective of this paper is to identify the political conditions that are most likely to be conducive to the development of social investment policies. It starts from the view put forward by theorists of welfare retrenchment that in the current context of permanent austerity, policy is likely to be dominated by retrenchment and implemented in a way that allows governments to minimise the risk of electoral punishment (blame avoidance). It is argued that this view is inconsistent with developments observed in several European countries, were some welfare state expansion has taken place mostly in the fields of childcare and active labour market policy. An alternative model is put forward, that emphasises the notion of "affordable credit claiming". It is argued that even under strong budgetary pressures, governments maintain a preference for policies that allow them to claim credit for their actions. Since the traditional redistributive policies tend to be off the menu for cost reasons, governments have tended to favour investments in childcare and active labour market policy as credit claiming tools. Policies developed in this way while they have a social investment flavour, tend to be rather limited in the extent to which they genuinely improve prospects of disadvantaged people by investing in their human capital. A more ambitious strategy of social investment sees unlikely to develop on the basis of affordable credit claiming. The paper starts by presenting the theoretical argument, which is then illustrated with examples taken from European countries both in the pre-crisis and in the post-crisis years.

Permanent.Plot.ch - a database for Swiss permanent vegetation plots

The aim of the Permanent.Plot.ch project is the conservation of historical data about permanent plots in Switzerland and the monitoring of vegetation in a context of environmental changes (mainly climate and land use). Permanent plots are currently being recognized as valuable tools to monitor long-term effects of environmental changes on vegetation. Often used in short studies (3 to 5 years), they are generally abandoned at the end of projects. However, their full potential might only be revealed after 10 or more years, once the location is lost. For instance, some of the oldest permanent plots in Switzerland (first half of the 20th century) were nearly lost, although they are now very valuable data. The Permanent.Plot.ch national database (GIVD ID EU-CH-001), by storing historical and recent data, will allow to ensuring future access to data from permanent vegetation plots. As the database contains some private data, it is not directly available on internet but an overview of the data can be downloaded from internet (http://www.unil.ch/ppch) and precise data are available on request.

Alpine deformation and 40Ar/39Ar geochronology of synkinematic white mica in the Siviez-Mischabel Nappe, western Pennine Alps, Switzerland

We explore the timing of deformation and exhumation of the Siviez-Mischabel Nappe (western Swiss Alps), which has been considered a classic example of a midcrustal crystalline nappe since the studies of Argand [1916]. This study presents Ar-40/Ar-39 ages obtained on both synkinematic white mica from Permo-Triassic cover sediments and more complex white mica populations from basement gneisses of the Siviez-Mischabel and middle Pennine Nappes. Primary foliation developed in cover units by nucleation, growth, and rigid rotation of mica grains during noncoaxial Alpine deformation. Although some samples show a crenulation of this primary foliation, mica growth appears to have occurred only during the development of primary foliation, the main phase of greenschist facies deformation related to imbrication of the Siviez-Mischabel Nappe and other middle Pennine Nappes. Good agreement exists between independent estimates of the timing of deformation and reported Ar-40/Ar-39, white mica ages from cover units of the central and southern Siviez-Mischabel Nappe. In cover units from the central and southern Siviez-Mischabel regions of the study area, Ar-40/Ar-39 ages appear to date synkinematic white mica growth. Results suggest that the Siviez-Mischabel :Nappe was emplaced and developed foliation during a 5 m.y. period from 41 to 36 Ma. In cover units from the eastern Siviez-Mischabel, however, Ar-40/Ar-39 white mica ages appear to date postkinematic thermal events. These thermal events may be related to Oligocene magmatic activity in the lower Pennine Nappes or to Miocene development of the Simplon fault zone. Variations in the relation between Alpine age and grain size for cover samples from the central, eastern, and southern Siviez-Mischabel correlate well with the regional variations in temperature inferred from quartz microfabrics and the pattern of regional metamorphism. When considered in concert with other recent isotopic studies on the timing of major tectonic and thermal events in the western Swiss Alps, these data support arguments that the relative timing of events such as thrusting and back thrusting of crystalline nappes in hinterland units and exhumation of high-pressure units in the suture zone of the western Alps are intimately related and synchronous on the scale of a few million years.

Juxtaposition of melt impregnation and high-temperature shear zones in the upper mantle; field and petrological constraints from the Lanzo peridotite (Northern Italy)

Results of a field and microstructural study between the northern and the central bodies of the Lanzo plagioclase peridotite massif (NW Italy) indicate that the spatial distribution of deformation is asymmetric across kilometre-scale mantle shear zones. The southwestern part of the shear zone (footwall) shows a gradually increasing degree of deformation from porphyroclastic peridotites to mylonite, whereas the northeastern part (hanging wall) quickly grades into weakly deformed peridotites. Discordant gabbroic and basaltic dykes are asymmetrically distributed and far more abundant in the footwall of the shear zone. The porphyroclastic peridotite displays porphyroclastic zones and domains of igneous crystallization whereas mylonites are characterized by elongated porphyroclasts, embedded between fine-grained, polycrystalline bands of olivine, plagioclase, clinopyroxene, orthopyroxene, spinel, rare titanian pargasite, and domains of recrystallized olivine. Two types of melt impregnation textures have been found: (1) clinopyroxene porphyroclasts incongruently reacted with migrating melt to form orthopyroxene plagioclase; (2) olivine porphyroclasts are partially replaced by interstitial orthopyroxene. The meltrock reaction textures tend to disappear in the mylonites, indicating that deformation in the mylonite continued under subsolidus conditions. The pyroxene chemistry is correlated with grain size. High-Al pyroxene cores indicate high temperatures (11001030C), whereas low-Al neoblasts display lower final equilibration temperatures (860C). The spinel Cr-number [molar Cr/(Cr Al)] and TiO2 concentrations show extreme variability covering almost the entire range known from abyssal peridotites. The spinel compositions of porphyroclastic peridotites from the central body are more variable than spinel from mylonite, mylonite with ultra-mylonite bands, and porphyroclastic rocks of the northern body. The spinel compositions probably indicate disequilibrium and would favour rapid cooling, and a faster exhumation of the central peridotite body, relative to the northern one. Our results indicate that melt migration and high-temperature deformation are juxtaposed both in time and space. Meltrock reaction may have caused grain-size reduction, which in turn led to localization of deformation. It is likely that melt-lubricated, actively deforming peridotites acted as melt focusing zones, with permeabilities higher than the surrounding, less deformed peridotites. Later, under subsolidus conditions, pinning in polycrystalline bands in the mylonites inhibited substantial grain growth and led to permanent weak zones in the upper mantle peridotite, with a permeability that is lower than in the weakly deformed peridotites. Such an inversion in permeability might explain why actively deforming, fine-grained peridotite mylonite acted as a permeability barrier and why ascending mafic melts might terminate and crystallize as gabbros along actively deforming shear zones. Melt-lubricated mantle shear zones provide a mechanism for explaining the discontinuous distribution of gabbros in oceancontinent transition zones, oceanic core complexes and ultraslow-spreading ridges.

Implementació d'estratègies de pràctica reflexiva en la formació inicial i permanent dels mestres

La recerca formativa que es presenta a continuació s'ha dut a terme durant els cursos acadèmics 2008-2009 i 2009-2010, en l'àmbit de la formació de mestres, amb grups d'estudiants de primer i en el marc de les assignatures de Didàctica i Organització Educativa del nou grau d'Educació Infantil. Per dur-la a terme s'ha disposat de la col·laboració de mestres en actiu de l'etapa d'educació infantil de diferents escoles de Barcelona. Aquesta recerca ha facilitat la incorporació d'estratègies de pràctica reflexiva a partir de la participació directa dels estudiants en entorns d'aprenentatge propis de l'exercici docent: les aules d'educació infantil. La intervenció dels estudiants ha estat possible gràcies a l'organització i la planificació curricular de les escoles en diferents espais i ambients d'aprenentatge, que han permès un treball col·laboratiu entre mestres, estudiants i professorat. Els resultats d'aquesta recerca han estat la implementació de metodologies de formació de pràctica reflexiva (millora personal i professional), la relació entre l'ensenyament universitari i el món laboral (teoria i pràctica) i l¿adquisició d'habilitats i competències dels estudiants i professionals (novells i experts), resultats que contribueixen a millorar l'acció docent a través de la participació conjunta de dos col·lectius: universitat i escola.

Assessorar o dirigir. El paper de l'assessor col·laboratiu en una formació permanent centrada en el professorat i en el context

En el artículo se realiza un análisis del campo de la formación del profesorado y del modelo de formación permanente de los últimos tiempos, atendiendo los nuevos elementos que actuaron como fuerzas ocultas e impulsoras de un pensamiento formativo innovador. Se analizan también las condiciones para un cambio en la manera de ver la formación permanente del profesorado que, progresivamente, ha pasado de una visión de producto formativo que el profesorado debía asimilar acríticamente, a otra etapa con visiones diversificadas. A continuación, se profundiza la función asesora y los modelos que esta nueva concepción de la formación exigen. Se necesitan asesores, formadores que de manera colaborativa ayuden a reconstruir la práctica educativa.

Claus per als itineraris de formació permanent del professorat de secundària

La formación permanente del profesorado (FPP) de Secundaria debería concebirse y llevarse a cabo considerando no sólo las prioridades de las políticas educativas sino también, y sobre todo, los escenarios laborales y las circunstancias peculiares en las que trabaja ese colectivo profesional. Los itinerarios constituyen una herramienta adecuada para ofrecer un dispositivo ordenado de oportunidades de formación que concilia las necesidades de los docentes y directivos, de los centros y de la Administración Educativa. Diseñar e implementar itinerarios comporta algunas consecuencias para las instituciones de FPP y los profesionales que trabajan en ellas, respecto a los recursos que se precisan y en relación con los sistemas y métodos de trabajo.

La Formació permanent del professorat a Catalunya. Una visió a través del tractament de la formació de formadors i formadores en els plans institucionals.

L'article fa un recorregut històric pels plans de formació permanent del professorat d'infantil, primària i secundària a Catalunya. Centra l'anàlisi de l'evolució de la formació permanent en el tractament que els diferents plans de formació han fet de la figura del formador de formadors. Aquest element permet anar establint els aspectes que han suposat els moments de canvi. Es veu el progressiu distanciament de la formació de les universitats i la creixent institucionalització dels plans de formació. També s'exposa la dicotomia entre els objectius que es plantegen i l'escassa preparació i consideració que els plans atorguen a aquests professionals, deixant en un limbe poc definit les funcions, responsabilitats i atribucions que se'ls atorga.

L'educació permanent: la història d'una idea

El fet de viure i de formar part d'una comunitat suposa, per a les persones que la integren, un procés de socialització i d'aprenentatge continuat. La creació i la transmissió de la cultura d'una generació a l'altra implica unes modalitats d'aprenentatge que transcendeixen el temps i l'espai limitats de l'educació formal, per comprendre pràcticament qualsevol moment i situació de la vida. Així doncs, el concepte de l'educació permanent no és un descobriment pedagògic modern, esta present en la practica de la humanitat des deis seus orígens, i podem trobar referencies sobre aquest tema en les antigues civilitzacions xinesa, índia, grega, al cristianisme, a l'humanisme, al Renaixement, etc. Però és durant el període il·lustrat quan la idea d'una educació per a tothom més enllà de la infància i de l'adolescència s'expressa amb més claredat que en èpoques anteriors.

Detection of millimetric deformation using a terrestrial laser scanner: experiment and application to a rockfall event

Terrestrial laser scanning (TLS) is one of the most promising surveying techniques for rockslope characterization and monitoring. Landslide and rockfall movements can be detected by means of comparison of sequential scans. One of the most pressing challenges of natural hazards is combined temporal and spatial prediction of rockfall. An outdoor experiment was performed to ascertain whether the TLS instrumental error is small enough to enable detection of precursory displacements of millimetric magnitude. This consists of a known displacement of three objects relative to a stable surface. Results show that millimetric changes cannot be detected by the analysis of the unprocessed datasets. Displacement measurement are improved considerably by applying Nearest Neighbour (NN) averaging, which reduces the error (1¿) up to a factor of 6. This technique was applied to displacements prior to the April 2007 rockfall event at Castellfollit de la Roca, Spain. The maximum precursory displacement measured was 45 mm, approximately 2.5 times the standard deviation of the model comparison, hampering the distinction between actual displacement and instrumental error using conventional methodologies. Encouragingly, the precursory displacement was clearly detected by applying the NN averaging method. These results show that millimetric displacements prior to failure can be detected using TLS.

Treatment of ruptured abdominal aortic aneurysm, a permanent challenge or a waste of resources? Prediction of outcome using a multi-organ-dysfunction score.

OBJECTIVES: in a retrospective study, attempts have been made to identify individual organ-dysfunction risk profiles influencing the outcome after surgery for ruptured abdominal aortic aneurysms. METHODS: out of 235 patients undergoing graft replacement for abdominal aortic aneurysms, 57 (53 men, four women, mean age 72 years [s.d. 8.8]) were treated for ruptured aneurysms in a 3-year period. Forty-eight preoperative, 13 intraoperative and 34 postoperative variables were evaluated statistically. A simple multi-organ dysfunction (MOD) score was adopted. RESULTS: the perioperative mortality was 32%. Three patients died intraoperatively, four within 48 h and 11 died later. A significant influence for pre-existing risk factors was identified only for cardiovascular diseases. Multiple linear-regression analysis indicated that a haemoglobin <90 g/l, systolic blood pressure <80 mmHg and ECG signs of ischaemia at admission were highly significant risk factors. The cause of death for patients, who died more than 48 h postoperatively, was mainly MOD. All patients with a MOD score >/=4 died (n=7). These patients required 27% of the intensive-care unit (ICU) days of all patients and 72% of the ICU days of the non-survivors. CONCLUSION: patients with ruptured aortic aneurysms from treatment should not be excluded. However, a physiological scoring system after 48 h appears justifiable in order to decide on the appropriateness of continual ICU support.

Renovació pedagógica i formació permanent

En dues ocasions anteriors i en circumstancies ben diferents per alguns de nosaltres, hem opinat o escrit sobre la formació permanent del professorat des d'aquesta "Tribuna» de Tempsd'Educació, per descriure les previsions del Pla de Formació del Departament d'Ensenyament (núm. 2, 1990) o per opinar i comentar les orientacions de la Comunitat Europea sobre la materia (núm. 5, 1991). En aquesta ocasió intentem aproximar-nos al tema des de la perspectiva de la Renovació Pedagógica i reflexionar sobre la marxa i la situació actual del Pla de Formació.

Elastic stresses and plastic deformations in 'Santa Clara' tomato fruits caused by package dependent compression

The objective of this work was to study the fruit compression behavior aiming to develop new tomato packages. Deformations caused by compression forces were observed inside packages and in individual 'Santa Clara' tomato fruit. The forces applied by a transparent acrylic lever to the fruit surface caused pericarp deformation and the flattened area was proportional to the force magnitude. The deformation was associated to the reduction in the gas volume (Vg), caused by expulsion of the air from the loculus cavity and reduction in the intercellular air volume of the pericarp. As ripening advanced, smaller fractions of the Vg reduced by the compressive force were restored after the stress was relieved. The lack of complete Vg restoration was an indication of permanent plastic deformations of the stressed cells. Vg regeneration (elastic recovery) was larger in green fruits than in the red ones. The ratio between the applied force and the flattened area (flattening pressure), which depends on cell turgidity, decreased during ripening. Fruit movements associated with its depth in the container were observed during storage in a transparent glass container (495 x 355 x 220 mm). The downward movement of the fruits was larger in the top layers because these movements seem to be driven by a summation of the deformation of many fruits in all layers.
