Reflectivity, graphic-pictorial activities and art: A virtuous circle
No full textThe link between the reflective thought and enjoyment of works of art and other graphic-pictorial activities is examined in the light of the scientific literature, methodological issues and practical proposals. The art and graphic-pictorial productions are intended as mentalistic exercises, as they form an 'inter-mental reality' that promotes a 'meeting of minds' and trigger the hypotheses (mentalistic reasoning) about the relationship between the representations of the author of the artwork, the subject depicted in the artwork, the artwork and the viewer herself. They are therefore representational mediators for communication between minds. Their communicative function is presented in its crucial aspects: Indicate the external references and, at the same time, evoke the author's state of mind, as well as suggesting aspects of the mind of the viewer himself. In educational practice, observing or producing expressive works, discussing them, enhancing the process of construction of meanings that emerges, helps to process the narrative and reflective tendency of children and adults. Psychological research confirms that these activities support the mentalistic ability, the reflectivity and intentionality attribution and can become the means to interpret and understand the world in an intersubjective perspective: the artist's painting, but also the graphic and pictorial production of a child or an adult, are traces and clues that tell us something of their mind and of our own mind
Dynamics of Network Formation Processes in the Co-Author Model
No full textThis article studies the dynamics in the formation processes of a mutual consent network in game theory setting: the Co-Author Model. In this article, a limited observation is applied and analytical results are derived. Then, 2 parameters are varied: the number of individuals in the network and the initial probability of the links in the network in its initial state. A simulation result shows a finding that is consistent with an analytical result for a state of equilibrium while it also shows different possible equilibria.Dynamics, Network, Game Theory, Model,Simulation, Equilibrium, Complexity
Similarities and Differences in Theoretical and Methodological Approaches of Gilli and Touraine
No full textU radu se prikazuju osnovne sličnosti i razlike teorijsko-metodološfeih pristupa dvojice suvremenih sociologa, Gillia i Tourainea. Prvo se ilustrira metodologija primjenjena u knjizi G. A. Gillia »Kako se istražuje« )1972), a zatim metodologija izložena u knjiizi »Sociologija društvenih pokreta« (1978) A. Tourainea. Suočeni sa činjenicom naučne insuficijentnosti pozitivističke orijentacije u sociologiji, autori postuliraju koncept nove metodologije poznate u sociološkoj suvremenosti kao akcijsko istraživanje. Članak završava imenovanjem nekih nedostataka ove metodološke orijentacije.In the article the author shows the main similarities and üill'erences in theoretical ana methodological approaches of two contemporary sociologists, Gilli and Touraine. First the author illustrates the methodology applied in Gilli’s »Come si fa ricerca« (1972, Milano) and then in Touraine’s »La voix et le regard« (1978, Paris). Faced with the fact of scientific insufficiency of positivism, both sociologists postulate a new methodology in the contemporary sociology known as action research. Finally the author points out certain drawbacks of this methodological orientation
Human–climate interactions in the central Mediterranean region during the last millennia: The laminated record of Lake Butrint (Albania)
No full textLake Butrint (39°47 N, 20°1 E) is a ca. 21 m deep, coastal lagoon located in SW Albania where finely-laminated sediments have been continuously deposited during the last millennia. The multi-proxy analysis (sedimentology, high-resolution elemental geochemistry and pollen) of a 12 m long sediment core, supported by seven AMS radiocarbon dates and 137Cs dating, enable a precise reconstruction of the environmental change that occurred in the central Mediterranean region during the last ∼4.5 cal kyrs BP. Sediments consist of triplets of authigenic carbonates, organic matter and clayey laminae. Fluctuations in the thickness and/or presence of these different types of seasonal laminae indicate variations in water salinity, organic productivity and runoff in the lake's catchment, as a result of the complex interplay of tectonics, anthropogenic forcing and climate variability. The progradation of the Pavllo river delta, favoured by variable human activity from the nearby ancient city of Butrint, led to the progressive isolation of this hydrological system from the Ionian Sea. The system evolved from an open bay to a restricted lagoon, which is consistent with archaeological data. An abrupt increase in mass-wasting activity between 1515 and 1450 BC, likely caused by nearby seismic activity, led to the accumulation of 24 homogenites, up to 17 cm thick. They have been deposited during the onset of finely laminated sedimentation, which indicates restricted, anoxic bottom water conditions and higher salinity. Periods of maximum water salinity, biological productivity, and carbonate precipitation coincide with warmer intervals, such as the early Roman Warm Period (RWP) (500 BC–0 AD), the Medieval Climate Anomaly (MCA) (800–1400 AD) and recent times (after 1800 AD). Conversely, lower salinity and more oxic conditions, with higher clastic input were recorded during 1400–500 BC, the Late Roman and the Early Medieval periods (0–800 AD) and during the Little Ice Age (1400–1800 AD). Hydrological fluctuations recorded in Butrint are in phase with most central and western Mediterranean records and correlate with NAO variability. In contrast, opposite hydrological patterns have been recorded in the Eastern Balkans and the Levant during the last millennium, emphasizing a complex spatial variability in the region. Phases of maximum settlement intensity in Butrint (Roman-Late Antique) coincide with warmer and/or stable climate periods (0–800 AD and MCA, respectively), indicating a long-term influence of climatic conditions on human activities. The Late Holocene sedimentary record of Lake Butrint demonstrates the complex interplay of climate variability, tectonics and human impact in the recent evolution of coastal Mediterranean regions

Lake-level changes in central Patagonia (Argentina): crossing environmental thresholds for Lateglacial and Holocene human occupation
No full textThe role and extent of climate as a cause of the expansion and decline of human cultures is still debatable. It is clear, however, that human-environment interactions are enhanced and interplay more closely in climatically sensitive areas such as around hydrologically closed basins. Lago Cardiel is located at 49° S in the very arid rain shadow east of the Andes, providing an exceptionally receptive system to changes in hydrological balance. Results of a geophysical survey combined with sedimentological and geochemical studies provide a continuous Lateglacial-Holocene record of substantial water-level changes. These variations, combined with archaeological results from the catchment area, offer a unique possibility to explore the pattern of peopling within this remote area of the globe and its possible relation to climate change. Human occupation in Patagonia is well documented towards the Andes throughout the entire Holocene. Archaeological data from the Lago Cardiel basin, however, show an apparent lack of human activity during the first part of this period, which coincides with well-constrained high lake levels. Our results show an intriguing coincidence between low lake level and increasing human occupation, suggesting that the Lago Cardiel basin has focused human use during intervals with relatively lower effective moisture such as during the Late Pleistocene, but its evidence may have been submerged. This interpretation is confirmed by archaeological remains from Lago Strobel, another perennial lake with a comparable catchment located in the same climatic region and thus sharing the same climatic history as Lago Cardiel.
