An assessment of the impact of possible CAP reform scenarios on Romanian agriculture
No full textUsing a simplified model, with key-variable the prices of two different possible scenarios of CAP reform after 2013 (moderate and radical), this paper present a comparison between the price effects of implementation of each reform scenario at 2015 horizon on Romanian agriculture. This short analysis shows that, under the presented hypotheses, the net welfare effect, due to the price changes, for the selected products, is positive in both reform scenarios, yet greater in the case of the radical reform. Integrated in the large context of Romanian development, it seems that the influence of CAP reform upon agriculture and rural areas will be most likely a gradual one: an interpenetration between the two scenarios is foreseeable, starting with the moderate reform that will dominate the period around 2013, the reform measures acquiring a more radical character afterwards.CAP reform, Romania, welfare effects, Agricultural and Food Policy,
Moving towards happiness? Understanding travel moods through twitter data in Turin
No full textThe paper will address the following questions: does urban mobility matter for health, and mental health in particular? How does each transport mode relate to our level of stress/happiness? A previous study conducted on Turin (Melis et al. 2015) showed that among indicators related to urban structure and social composition, ‘accessibility by public transport’ seems to be the one with strongest relation with mental health (depression) outcomes. Starting from this results, we decided to further explore this association through the use of data from social media. Recent trends in the use of social networks have opened up new opportunities in the field of urban and transport studies: the great amount of data coming from Twitter is an example, providing easily available, often geo-referenced, marginally costly, datasets offering new insights on individual and collective life. The accuracy and reliability, as well as representativeness of the results coming from the use of this new source of data in the mobility and planning field is undoubtedly growing. The project uses Twitter data collected for the metropolitan area of Turin (IT) and analyses it using a Semantic Analysis algorithm to show spatiotemporal levels of happiness (valence) of users, related to the transport mode they have been using. Geographic Information Systems (GIS) and spatial analysis techniques are then used to visualize spatial patterns and associations among happiness levels and contextual variables, such as land-use. From a methodological point of view, results can be compared to research conducted on US cities by Flint University (Rybarczyk and Banerjee 2015), as the method used is the same. The purpose of the study is exploratory, in order to understand which use can be done of such a rich data source as social media information. Therefore, the results may be used to promote the use of social media data by transportation planners and public health officials for developing more effective transportation plans and policies, as well as to understand the degree of satisfaction/stress linked to different transport modes
Rich, Sturmian, and trapezoidal words
No full textIn this paper we explore various interconnections between rich words, Sturmian words, and trapezoidal words. Rich words, first introduced by the second and third authors together with J. Justin and S. Widmer, constitute a new class of finite and infinite words characterized by having the maximal number of palindromic factors. Every finite Sturmian word is rich, but not conversely. Trapezoidal words were first introduced by the first author in studying the behavior of the subword complexity of finite Sturmian words. Unfortunately this property does not characterize finite Sturmian words. In this note we show that the only trapezoidal palindromes are Sturmian. More generally we show that Sturmian palindromes can be characterized either in terms of their subword complexity (the trapezoidal property) or in terms of their palindromic complexity. We also obtain a similar characterization of rich palindromes in terms of a relation between palindromic complexity and subword complexity

No full textComplesso preistorico di Monte Baranta (Olmedo - SS): relazione sulla campagna di scavi 2012
No full textDuring September and October 2012 archaeological excavations reopened in the prehistoric complex of Monte Baranta (Olmedo -SS), under license to Alberto Moravetti (University of Sassari).The archaeological site of Monte Baranta was partially explored in the years 1979-81 and materials found dated the construction of the complex to the Copper Age (Culture of Monte Claro).In the 2012 campaign have been explored five of the six small huts of the village, while the sixth (hut no. 2), entirely excavated in previous campaigns, has been the object of limited tests outside.In the hut 1, current excavation has brought to light a floor of rough stones of medium and small size, in which is embedded a small quadrangular stone structure, perhaps a hearth (?).The hut 3, also quadrangular, had a similar hearth made on the floor, and another elliptical structure realized with orthostatic stones partially sunken in a central area of the hut (a grave?). The hut 4, only partially preserved, also shows the presence of a small quadrangular structure of stones sunken below the floor level.The huts 5 and 6, contiguous, showed the presence of a pavement stones arranged with a certain care; in the hut 6 is present a probable posthole in a central position, while in the hut 5 has been brought to light the usual quadrangular stone structure sunken below the floor level.The materials found have confirmed the chronology of the structures in the Monte Claro period, while there are no traces of post-Chalcolithic phases
Embedding media for cryomicrotomy: an applicative reappraisal
No full textWe reassess here the formulation of cryoembedding media in connection with recent developments in commercial cryomicrotomes. Water-based solutions of polyvinyl alcohols were our starting media, and each of 2 different polymers (56-98, MW ∼195000; and 6-98, MW ∼47000) showed a critical concentration for optimum sectioning. At higher or lower polymer concentrations, wrinkles and folds became apparent in tissue areas of sections, or in the sectioned embedding medium areas between tissues, respectively. Addition of polyethylene glycol (MW 380-420) further facilitated and improved sectioning, resulting in frozen tissue blocks that cut well in the 2 to 100 μm range and further, using disposable blades throughout. Applying a wide temperature differential between tissue specimen (-11°C to -13°C) and cutting knife (-33°C to -35°C), serial adjacent sections were reproducibly obtained at a 2-μm setting, singly or in short ribbons. Embedding media of low and high viscosity were obtained, depending on the polyvinyl alcohol polymer used, and could be applied sequentially for tissue infiltration followed by embedding with precise sample orientation. When required, media were made semisolid by addition of carboxymethylcellulose
