Media activism on and off line by Italian adolescents and young adults

From several researchers it appears that Italian adolescents and young people are grown up with commercial television which is accused to contain too much violence, sex, reality shows, advertising, cartoons which are watched from 1 to 4 hours daily. Adolescents are also great users of mobile phones and spend a lot of time to use it. Their academic results are below the average of Ocse States. However the widespread use of communication technology and social networks display also another side of adolescents who engage in media activism and political movement such as Ammazzateci tutti!, Indymedia, Movimento 5 Stelle, Movimento No Tav. In which way does the world economic crisis -with the specific problems of Italy as the cutting founds for school, academic research and welfare, the corruption of political class, mafia and camorra organisation induce a reaction in our adolescents and young people? Several researches inform us about their use of internet in terms of spending time but, more important, how internet, and the web 2.0, could be an instrument for their reaction? What do they do online? How they do it? Which is the meaning of their presence online? And, has their online activity a continuity offline? The research aims are: 1. Trough a participant observation of Social Network profiles opened by 10 young active citizens, I would seek to understand which kind of social or political activities they engage in online as individuals and which is the meaning of their presence online. 2. To observe and understand if adolescents and young people have a continuity of their socio-political engagement online in offline activities and which kind of experiences it is. 3. Try to comprehend which was (or which were) the significant, learning experiences that convinced them about the potential of the web as tool for their activism.

La rappresentazione della cultura arabo-islamica nei libri di storia per la scuola secondaria di primo grado. Uno sguardo particolare sull'immagine della donna musulmana

Il presente lavoro di ricerca si focalizza sulla rappresentazione della cultura arabo-islamica, così come viene restituita nei libri di storia per la scuola secondaria di primo grado. Il fatto che il mondo di oggi è caratterizzato, ora più che mai, da continui e inevitabili incontri tra persone con multiple appartenenze esige un forte impegno volto a favorire pacifici rapporti interculturali. A tale scopo si ritiene che i contenuti dei libri di testo abbiano un ruolo molto rilevante. Di qui, uno degli obiettivi consiste nel verificare se i libri di testo veicolano un’efficace educazione alla conoscenza e al rispetto delle altre culture e religioni, all’ascolto e al dialogo interculturale; nonché al superamento dell'etnocentrismo, degli stereotipi e dei pregiudizi. Si è cercato così di verificare – nel campione dei libri di testo presi in esame – quali eventuali pregiudizi ricorrenti, stereotipi o prospettive etnocentriche vengono costruite, consolidate, reiterate e trasmesse, consapevolmente o inconsapevolmente, attraverso le affermazioni o le immagini che illustrano la cultura arabo-islamica. La prima parte della tesi, quella teorica, è dedicata all'approfondimento di due temi: il primo riguarda il rapporto Oriente-Occidente e la rappresentazione dell'altro e il secondo riguarda invece la condizione della donna musulmana tra stereotipi e realtà. La seconda parte invece, quella empirica, è dedicata principalmente all'analisi del contenuto dei testi di storia. Dall'analisi effettuata è evidente l'interesse, da parte degli autori e degli editori dei libri di testo, per il tema della cultura arabo-islamica. Nonostante ciò, si è potuto riscontrare nei libri presi in esame, sebbene in misura differente, la presenza (o compresenza) di stereotipi, generalizzazioni e informazioni parziali, imprecise o errate attorno alla cultura arabo-islamica e a chi vi appartiene.

Sfide familiari e disabilita'. Il ruolo educativo dei padri

Il progetto si pone in sintonia con i nuovi scenari di ricerca – sia in ambito nazionale che internazionale - della Pedagogia Speciale per l’inclusione e la piena e attiva partecipazione all’interno della società delle persone con disabilità e delle loro famiglie (Convenzione Onu, 2006). La riflessione sul ruolo educativo del padre riguardo alla disabilità di un/una figlio/a è una questione complessa e controversa che necessita di una premessa che ponga al centro dell’attenzione pedagogica la funzione paterna in senso ampio. L’obiettivo principale del progetto è quello di indagare il ruolo educativo del padre – nelle situazioni di disabilità - con riflessioni più ampie riguardanti le funzioni parentali, i modelli di genitorialità e l’educare nella nostra società.I risultati attesi potranno gettare luce su alcune Linee Guida - riguardo alla presa in carico della famiglia e del sostegno alla genitorialità - utili ai professionisti impegnati in quest’area e agli educatori dei servizio socio-educativi e sanitari.

La Città Inclusiva. Educazione, democrazia e giustizia sociale: la ricerca di una prospettiva e di strategie che promuovano umanizzazione e inclusione

L'interrogativo da cui nasce la ricerca riguarda la possibilità di individuare, in controtendenza con la logica neoliberista, strategie per l'affermarsi di una cultura dello sviluppo che sia sostenibile per l'ambiente e rispettosa della dignità delle persone, in grado di valorizzarne le differenze e di farsi carico delle difficoltà che ognuno può incontrare nel corso della propria esistenza. Centrale è il tema del lavoro, aspetto decisivo delle condizioni di appartenenza sociale e di valorizzazione delle risorse umane. Vengono richiamati studi sulla realtà in cui siamo immersi, caratterizzata dal pensiero liberista diventato negli ultimi decenni dominante su scala globale e che ha comportato una concezione delle relazioni sociali basata su di una competitività esasperata e sull’esclusione di chi non sta al passo con le leggi di mercato: le conseguenze drammatiche dell'imbroglio liberista; la riduzione delle persone a consumatori; la fuga dalla comunità ed il rifugio in identità separate; il tempo del rischio, della paura e della separazione fra etica e affari. E gli studi che, in controtendenza, introducono a prospettive di ricerca di uno sviluppo inclusivo e umanizzante: le prospettive della decrescita, del business sociale, di una via cristiana verso un'economia giusta, della valorizzazione delle capacità delle risorse umane. Vengono poi indagati i collegamenti con le esperienze attive nel territorio della città di Bologna che promuovono, attraverso la collaborazione fra istituzioni, organizzazioni intermedie e cittadini, occasioni di un welfare comunitario che sviluppa competenze e diritti insieme a responsabilità: l'introduzione delle clausole sociali negli appalti pubblici per la realizzazione professionale delle persone svantaggiate; la promozione della responsabilità sociale d'impresa per l'inclusione socio-lavorativa; la valorizzazione delle risorse delle persone che vivono un’esperienza carceraria. Si tratta di esperienze ancora limitate, ma possono costituire un riferimento culturale e operativo di un modello di sviluppo possibile, che convenga a tutti, compatibile con i limiti ambientali e umanizzante.

Families Stories. Rappresentazioni di famiglie nella letteratura per l'infanzia in Europa e negli Stati Uniti

In questa tesi dottorale viene preso in analisi il tema della famiglia, uno degli elementi fondanti della riflessione pedagogica, crocevia di una molteplicità di nuclei interpretativi con diramazioni e contaminazioni, con mutamenti attraverso le epoche storiche, rappresentati in pagine contenute nei Classici della letteratura per l’infanzia e nei migliori libri di narrativa contemporanea. Si tratta di un tema di grande ampiezza che ha comportato una scelta mirata di Autori che, nei loro romanzi hanno trattato questioni riguardanti la famiglia nelle sue pluralità delle sue tante accezioni, dalla vita familiare agli abbandoni, dalle infanzie senza famiglia alle famiglie altre. Nelle diverse epoche storiche, le loro narrazioni hanno lasciato un segno per l'originalità interpretativa che ancora oggi ci raccontano storie di vie familiale Dai romanzi ottocenteschi alle saghe fantasy degli ultimi cinquant’anni, fino ai picturebook, destinati ai più piccoli, le families stories possono costituire un materiale pedagogico privilegiato, sia offrendo occasioni di scoperta e conoscenza di sé e del mondo, attraverso le quali i lettori bambini, enigmatici frontalieri, varcano soglie verso altrovi misteriosi, sia fornendo spunti agli studiosi per approfondire tematiche multiple e complesse. Le families stories riflettono spesso in maniera critica le divergenze che possono manifestarsi tra le prassi individuate e studiate dalle scienze umane e sociali e le metafore narrative proposte dai numerosi Autori della letteratura per l’infanzia. Proponendo una prospettiva spesso spiazzante, esse interpretano la realtà a fondo, cogliendo i più piccoli ed inosservati particolari che, invece, hanno la capacità di rompere gli schemi socio-educativi dell’epoca storica in cui le storie prendono vita.

La promozione dell'inclusione nei sistemi scolastici attraverso l'intervento di cooperazione internazionale: l'esperienza di El Salvador

La ricerca si colloca all’interno di un complesso intervento di cooperazione internazionale realizzato in El Salvador tra il 2009 e il 2014. Il Progetto di cooperazione è stato promosso dal Dipartimento di Scienze dell’Educazione dell’Università di Bologna e finanziato dalla Cooperazione Italiana. L’esperienza studiata rappresenta un esempio di promozione dell’inclusione nei sistemi scolastici di Paesi del Sud del mondo e si propone due obiettivi: 1) analizzare il processo di cambiamento della prospettiva di intervento promossa dalla cooperazione internazionale, evidenziando la dimensione educativa che sostiene processi di empowerment e ownership delle istituzioni locali; 2) contribuire al dibattito sull’ “inclusive education”, sostenendo processi di inclusione scolastica e sociale rivolti a tutti coloro che si trovano in situazione di svantaggio psico-fisico e/o socio-culturale. Le politiche locali del Ministero dell’Educazione dal 2009 hanno promosso un modello educativo con l’obiettivo di garantire il diritto all’educazione per tutti nella scuola pubblica. Lo studio costituisce un'indagine di tipo valutativo sul processo di sviluppo della scuola inclusiva in El Salvador, supportato dall’intervento di cooperazione internazionale. La ricerca utilizza in modo integrato strumenti di natura quantitativa (questionari) e qualitativa (interviste). Dai dati raccolti emerge come il processo di cooperazione sia stato caratterizzato dal principio della pari dignità tra esperti internazionali e autorità politiche e tecniche locali. Inoltre, la ricerca ha consentito di verificare come la cultura dell'inclusione si sia radicata in modo diffuso nella percezione della missione della scuola e il suo ruolo tra i protagonisti del sistema scolastico. Alla luce dei risultati, appare fondamentale continuare a investire sulla formazione tecnica delle figure chiave del sistema educativo; facilitare il processo di inclusione dei disabili nelle scuole regolari con una parallela trasformazione delle scuole speciali in centri di supporto all’integrazione; promuovere una sinergia di azione formativa tra il ministero, mondo accademico e della formazione professionale.

Nosocomial infection: A risk factor for a complicated course in children with respiratory syncytial virus infection - Results from a prospective multicenter German surveillance study

BACKGROUND: Nosocomially acquired respiratory syncytial virus infections (RSV-NI) may cause serious problems in hospitalized paediatric patients. Hitherto, prospectively collected representative data on RSV-NI from multicenter studies in Germany are limited. METHODS: The DMS RSV Ped database was designed for the prospective multicenter documentation and analysis of clinically relevant aspects of the management of inpatients with RSV-infection. The study covered six consecutive seasons (1999-2005); the surveillance took place in 14 paediatric hospitals in Germany. RESULTS: Of the 1568 prospectively documented RSV-infections, 6% (n=90) were NI and 94% (n=1478) were community acquired (CA). A significantly higher proportion in the NI group displayed additional risk factors like prematurity, chronic lung disease, mechanical ventilation (med. history), congenital heart disease, and neuromuscular impairment. Of all NI, 55% occurred in preterms (30.6% of all RSV-infections in preterms with severe chronic lung disease of prematurity were NI). Illness severity as well as the total mortality, but not the attributable mortality was significantly higher in the NI group. In the multivariate analysis, NI was significantly associated with the combined outcome 'complicated course of disease'. CONCLUSION: This is the first prospective multicenter study from Germany, which confirms the increased risk of a severe clinical course in nosocomially acquired RSV-infection. Of great concern is the high rate of (preventable) NI in preterms, in particular in those with severe chronic lung disease or with mechanical ventilation due to other reasons.

Hospitalized children with respiratory syncytial virus infection and neuromuscular impairment face an increased risk of a complicated course

BACKGROUND: Respiratory syncytial virus (RSV) infection is an important cause of viral respiratory tract infection in children. In contrast to other confirmed risk factors that predispose to a higher morbidity and mortality, the particular risk of a preexisting neuromuscular impairment (NMI) in hospitalized children with RSV infection has not been prospectively studied in a multicenter trial. METHODS: The DMS RSV Paed database was designed for the prospective multicenter documentation and analysis of all clinically relevant aspects of the management of inpatients with RSV infection. Patients with clinically relevant NMI were identified according to the specific comments of the attending physicians and compared with those without NMI. RESULTS: This study covers 6 consecutive seasons; the surveillance took place in 14 pediatric hospitals in Germany from 1999 to 2005. In total, 1568 RSV infections were prospectively documented in 1541 pediatric patients. Of these, 73 (4.7%) patients displayed a clinically relevant NMI; 41 (56%) NMI patients had at least 1 additional risk factor for a severe course of the infection (multiple risk factors in some patients; prematurity in 30, congenital heart disease in 19, chronic lung disease 6 and immunodeficiency in 8). Median age at diagnosis was higher in NMI patients (14 vs. 5 months); NMI patients had a greater risk of seizures (15.1% vs. 1.6%), and a higher proportion in the NMI group had to be mechanically ventilated (9.6% vs. 1.9%). Eventually, the attributable mortality was significantly higher in the NMI group (5.5% vs. 0.2%; P < 0.001 for all). Multivariate logistic regression confirmed that NMI was independently associated with pediatric intensive care unit (PICU) admission (OR, 4.94; 95% CI, 2.69-8.94; P < 0.001] and mechanical ventilation (OR, 3.85; 95% CI, 1.28-10.22; P = 0.017). CONCLUSION: This is the first prospective multicenter study confirming the hypothesis that children with clinically relevant NMI face an increased risk for severe RSV-disease. It seems reasonable to include NMI as a cofactor into the decision algorithm of passive immunization.

Effects of anticancer drug docetaxel on the structure and function of the rabbit olfactory mucosa

Docetaxel (DCT) is an anticancer drug which acts by disrupting microtubule dynamics in the highly mitotic cancer cells. Thus, this drug has a potential to affect function and organization of tissues exhibiting high cellular turnover. We investigated, in the rabbit, the effects of a single human equivalent dose (6.26mg/kg, i.v.) of DCT on the olfactory mucosa (OM) through light and electron microscopy, morphometry, Ki-67 immunostaining, TUNEL assay and the buried food test for olfactory sensitivity. On post-exposure days (PED) 5 and 10, there was disarrangement of the normal cell layering in the olfactory epithelium (OE), apoptotic death of cells of the OE, Bowman's glands and axon bundles, and the presence (including on PED 3) of blood vessels in the bundle cores. A decrease in bundle diameters, olfactory cell densities and cilia numbers, which was most significant on PED 10 (49.3%, 63.4% and 50%, respectively), was also evident. Surprisingly by PED 15, the OM regained normal morphology. Furthermore, olfactory sensitivity decreased progressively until PED 10 when olfaction was markedly impaired, and with recovery from the impairment by PED 15. These observations show that DCT transiently alters the structure and function of the OM suggesting a high regenerative potential for this tissue.

Fluctuations in Pigment Epithelial Detachment and Retinal Fluid Using a Bimonthly Treatment Regimen with Aflibercept for Neovascular Age-Related Macular Degeneration

PURPOSE To assess the effect of a bimonthly treatment regimen with intravitreal aflibercept on retinal fluid and pigment epithelial detachment (PED) in patients with neovascular age-related macular degeneration (AMD). METHODS Twenty-six treatment-naive eyes of 26 patients with choroidal neovascularisation secondary to AMD were included. The patients received three initial monthly (mean 30 days) intravitreal injections of aflibercept followed by a bimonthly (mean 62 days) fixed regimen for a total of 1 year. Best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) measurements were recorded at monthly intervals. In addition, the presence of intraretinal fluid (IRF) or subretinal fluid (SRF) or a combination of both as well as serous and fibrovascular PEDs were assessed. RESULTS The mean patient age was 80 years (range 54-93). There were 14 male and 12 female patients. The mean gain in BCVA at 1 year was 9.3 letters (SEM ±3) with a mean reduction of the central retinal thickness of 154 µm (SEM ±50). After 3 monthly injections of aflibercept, there was resolution of IRF and SRF in 80% of the treated eyes; the amount of fluid increased at months 4, 6 and 8 with troughs in between. Whereas fibrovascular PEDs remained stable after the loading phase, serous PEDs displayed a seesaw pattern. Patients without retinal pigment epithelium (RPE) atrophy at the end of the 1-year period had significantly better BCVA compared to patients with RPE atrophy (p = 0.03). CONCLUSION Despite significant overall BCVA gain, bimonthly intervals seem insufficient to maintain the morphological improvements after the initial loading dose with intravitreal aflibercept.

Pollen and macroremains from sediment core Aschenhütte

The Upper Pleistocene sediments of the Aschenhütte sink-hole (west of Herzberg am Harz, Lower Saxony) enable one to make interesting correlations between palynological and geological results. The sequence is composed of limnic-telmatic deposits (Eemain to Lower Weichselian) and loess with paleosoils (Weichselian). Sedimentation started during the hornbeam-dominated phase of the Eemian interglacial period and continued throughout the Eemian, the Weichselian Brörup interstadial (sensu Andersen) and parts of the preceding and the following stadial phases, the Herning and the Rederstall stadials. As opposed to most of the known Eemian sites spruce was a major tree species during the hornbeam-dominated phase of the Eemian. The vegetational development during the interstadial phase does not show a period of climatic deterioration as is the case for the Brörup interstadial when considering regions with a more demanding vegetation or regions close to the natural boundaries of the tree species concerned. Pollen or seeds of Bruckenthalia and Picea omoricoides have not been found in the Aschenhütte cores. The limnic-telmatic sediments interlock with loess-paleosoils (Eemian soil and Lower Weichselian bleaching soils) at the lake shore. They are overlaid by loess paleosoils of the Stillfried-B interstadial (Hattorf soil and Lohne soil). Lake level fluctuations were determined by means of the facies distribution and isochrones as defined by pollen analysis. A relatively high stand of the lake level existed after the end of the Eemian interglacial and during the Brörup interstadial periods. In the course of the Herning stadial period the water level dropped, whereas during the Rederstall stadial phase the lake basin was covered by sediments and therefore dried up.

Pollen profiles from 8 sediment cores from the Degersee, Southern Germany

The discovery of a neolithic pile field in the shallow water near the eastern shore of the Degersee confirmed earlier palynological and sedimentological studies stating that early man was active in the region since more than 6000 years. The already available off-site data were freshly assessed, completed by additional data from old and new cores and the interpretations revised. A common time scale for the off-site data and the on-site data was obtained by AMS dating of terrestrial macro remains of the neolithic section of off-site core De_I+De_H. The ages can thus be parallelled with AMS ages of construction timber on-site. Pollen analyses from all cores provide a further time scale. The continuously and densely sampled pollen profile of the profundal zone embracing the entire Late glacial and Holocene serves as a reference. From the Boreal onwards the relative ages are transformed by AMS ages and varve counts into calibrated and absolute. A transect cored close to the neolithic pile field across the lake marl-platform demonstrates its geological architecture in the shallow water since the Lateglacial. Studies of the microfabric of thin sections of drilled cores and of box cores from the excavations demonstrate that neolithic settlements now at 2-3,5 m water depth had been erected on lake marl freshly fallen dry, thus indicating earlier lake levels dropped by 1.5-2 m. The neolithic section of the highly resolved off-site profile in the lake=s profundal zone has laminated and calcareous zones alternating with massive ones. Assemblages of diatoms and concentrations of trace elements changing simultaneously characterise the calcareous sections as deposits of low lake levels that lasted between some 40 and more than 300 years. The ages of discovered lake shore dwellings fall into calcareous segments with low lake levels. From the end of the Upper Atlantic period (F VII) appear Secondary Forest Cycles in the beech forest, a man-made sequence of repeated vegetational development with an identical pattern: With a decrease of beech pollen appear pollen of grasses, herbs and cultural indicators. These are suppressed by the light demanding hazel and birch, those again by ash, and finally by the shade demanding beech forming a new pollen peak. Seven main Forest Cycles are identified In the upper Neolithic period each comprising some 250, 450 or 800 years. They are subdivided into subcycles that can be broken down by very dense sampling in even shorter cycles of decadal length. Farming settlers have caused minor patchy clearances of the beech-mixed-forest with the use of fire. The phases of clearance coincide with peaks of charcoal and low stands of the lake levels. The Secondary Forest Cycles and the continuous occurrence of charcoal prove a continued occupation of the region. Together with the repeated restoration of the beech climax forest they point to pulsating occupation probably associated with dynamic demography. The synchronism of the many palynological, sedimentological and archaeological data point to an external forcing as the climate that affects comprehensively all these proxies. The fluctuations of the activity of the sun as manifested in the residual d14C go largely along with the proxies. The initial clearances at the begin of the forest cycles are linked to low lake levels and negative values of d14C that point to dry and warm phases of a more continental climate type. The subcycles exist independent from climatic changes, indicating that early man acted largely independent from external forces.

Pollen records of the Bykovsky Peninsula

New pollen and radiocarbon data from the Bykovsky Peninsula document the Late Pleistocene and Holocene environmental history of the Laptev Sea coast. More than 60 AMS-14C and conventional 14C dates indicate that the deposits accumulated during the last 60,000 radiocarbon yr BP. High concentration of green alga colonies (Pediustrum and Botryococcus) in the investigated sediment show that sedimentation was mostly in shallow water environments. Scarce grass and sedge communities dominated the vegetation 53-60 kyr BP. Climate was cold and dry. Open Poaceae and Cypcraccae associations with Asteraceae, Ranunculaceae, and Cichoriaceac, dominated in the area about 48-42.5 kyr BP. Steppic communities with Artemisia and shrubby tundra communities with Salix and Betula sect. Nanae were also present. Climate was dry, but relatively warm. Vegetation cover became denser about 42.5-33.5 kyr BP, reflecting more favorable climate conditions. Scarce Poaceae communities with some Caryophyllaceae, Asteraceae, Cichoriaceae, and Selaginella rupestris covered the Bykovsky Peninsula area during the Sartan (Late Weichselian) stage about 26-16 kyr BP. Disturbed, uncovered soils were very common in the area. Climate was extremely cold and dry. Poaceae and Cyperaceae associations with Caryophyllaceae, Asteraceae, Cichoriaceae dominated the vegetation in the late Sartan, ca 16-12.2 kyr BP. Climate was significantly warmer than in the early Sartan time. The lee Complex sedimentation was interrupted about 12 kyr BP; most likely it was connected with the beginning of the Allerod warnring. Shrubby (Betula sect. Nanae, Alnusfnuicosa, Salix, Ericales) tundra was widely distributed on the Bykovsky Peninsula during the early-middle Holacene. Climate was most favorable between 8200 and 4500 yr BP. Vegetation became similar to modern after 4500 yr BP, suggesting a deterioration of climate.

Pollen record and age determinations on four sites from Taymyr Peninsula, Russia

Pollen data from a Levinson-Lessing Lake sediment core (74°28'N, 98°38'E) and Cape Sabler, Taymyr Lake permafrost sequences (74°33'N, 100°32'E) reveal substantial environmental changes on the northern Taymyr Peninsula during the last c. 32 000 14C years. The continuous records confirm that a scarce steppe-like vegetation with Poaceae, Artemisia and Cyperaceae dominated c. 32 000-10 300 14C yr BP, while tundra-like vegetation with Oxyria, Ranunculaceae and Caryophyllaceae grew in wetter areas. The coldest interval occurred c. 18 000 yr BP. Lateglacial pollen data show several warming events followed by a climate deterioration c. 10 500 14C yr BP, which may correspond with the Younger Dryas. The Late Pleistocene/Holocene transition, c. 10 300-10 000 14C yr BP, is characterized by a change from the herb-dominated vegetation to shrubby tundra with Betula sect. Nanae and Salix. Alnus fruticosa arrived locally c. 9000-8500 14C yr BP and disappeared c. 4000-3500 14C yr BP. Communities of Betula sect. Nanae, broadly distributed at c. 10 000-3500 14C yr BP, almost disappeared when vegetation became similar to the modern herb tundra after 3500-3000 14C yr BP. Quantitative climate reconstructions show Last Glacial Maximum summer temperature about 4°C below the present and Preboreal (c. 10 000 14C yr BP) temperature 2-4°C above the present. Maximum summer temperature occurred between 10 000 and 5500 14C yr BP; later summers were similar to present or slightly warmer.

Pollen record from Kleiner Mochowsee, Germany

A Holocene pollen diagram from Kleiner Mochowsee (northern Niederlausitz, East Germany) shows pine as an important constituent of the woodland south of the Schwielochsee. Oak woodland was widespread since the Atlantic. Betula lost its importance at the end of the Preboreal. Fagus is represented continuously in the pollen record since the Atlantic, Carpinus since the Subboreal. However, the two latter tree species remain without great importance throughout the whole pollen record. The poor sandy soils are furthermore reflected by the low values of Corylus during the Boreal, comparable to other records from Berlin and its surrounding area. The 'classical' elm decline could be shown for the Niederlausitz, radiocarbon dates assume a contemporaneous age for this event with other records from northern Germany. Only small-scaled human impact is indicated in prehistoric times, during the migration period it seems to have ceased completely. Later, in the Medieval, deforestation and tillage can be shown. Secale was cultivated since the early Medieval; an accompanying weed flora appeared at the same time. Cultivation of Fagopyrum and Linum usitatissimum could be shown for the late Medieval times.
