Il verso della dissoluzione e quello della caduta. Notizie sull’orientamento architettonico tra Th. Lipps e H. van der Laan

The paper aims at drawing the main lines of a reflection about architectonic space, starting from the comparison between two hypothesis, as much as ever different: Theodor Lipps’ spatial aesthetics and Hans van der Laan’s elemental theory. The emphasis given by both authors to the intersection between directions and way, but also to the mutual subordination between thing and space, allows to rewrite the obituary of architecture as a spatial art, according to which the Modern Style has turned the spatiality into its specular visibility, into the spaciousness, into the indefinite continuity of the Bigness

Naturalizing Negation. A Challenge for Cognitive Phenomenology about Phenomenological Possess Conditions of Logical Vocabulary

The negation constitutes one of the main troubles for attempts to naturalise the semantics of the logical vocabulary, as shown by the problems related to the interpretation of disjunction in the treatment of error (Fodor) or to the definition of contraries in the analysis of reidentification abilities (Millikan). There seems to be no way out between “no (naturalized) negation, no grip of logic on the world” and “no (truth-functional) negation, no logic”. Unexpected help may come from the cognitive phenomenology of negation. For three reasons: • Firstly, because it allows a distinction to be made between semantic analysis, identification of the possession conditions and psychology of the acquisition of the notion of negation, a distinction whose absence produces many misunderstandings between those who support a naturalization of semantics and those who oppose it. • Then because it places negation at the level of the contrast between beliefs, a terrain that is hostile to some naturalizers. • Finally, because it makes it possible to define a peculiar type of liberalised naturalization of semantics and, consequently, to present a hypothesis for the naturalization of cognitive phenomenology

From the AKAP to AKAIE model to assess the uptake of technological innovations in the aquaculture sector

The purpose of this study is to explore the adoption of innovation in the aquaculture sector through the Awareness Knowledge Adoption Implementation Effectiveness (AKAIE) sequence. The AKAIE is an extension of the Awareness Knowledge Adoption Product (AKAP) model in order to better investigate the post-adoption phases. Using the ‘Implementation’ and ‘Effectiveness’ phases, this study aims to further the under- standing of both the different levels of adoption and the impact of innovation in terms of environmental, economic and social benefits produced. The proposed sequence is contextualised in light of the multidimensional scenario of on-farm and off-farm factors acting alongside the adoption of new technologies in the aquaculture sector. In this paper, the perspective of aquaculturists is represented with the con- cept of perceived complexity as the central node of the adoption process. The pro- posed tool could support policy makers in understanding and disseminating innovation in aquaculture

Do Rural Development Policies Really Help Small Farms? A Reflection from Italy

Although research and political intentions both recognise the crucial role of small farms in Rural Development (RD) strategies, in actual practice they are left out of the benefits of agricultural policies. This is not established by legislative or regulatory prescriptions. It is the result of consolidated practices driven by the productivist approach to agricultural development, overtaken by the concept of multifunctionality, which has inspired European intervention in the agricultural sector and rural areas for more than twenty years. This is particularly evident in Italy, where the weight of small farms is extremely significant in terms of numbers, farmland area and work generated. The continuity of small farms in Italy is of fundamental importance due to their economic, environmental and social relevance to the objective of reconnecting agriculture and territories in a circular vision of RD. Despite this crucial role, these farms have historically had great difficulty accessing RD programmes due to the national or regional implementation of these plans, which set access thresholds and procedural constraints that effectively exclude small farmers. The construction of a national strategy for rural areas requires specific attention to the universe of small farms, which should be included within the perimeter of the potential beneficiaries of RD policies

Precision farming: what do Italian farmers really think? An application of the Q methodology

Precision farming (PF) is a term that is now widespread throughout agricultural systems worldwide. It is studied in many ways, from its strictly technical connotation of a farm management strategy that uses information technology to support decision-making processes to the steppingstones and the dissection of the factors involved in the complex scenario of adopting related tools. Starting from the statement "In my opinion, precision farming is…", the present work investigates the perspective of the agricultural entrepreneur in conceptualising PF. Some researchers have highlighted the role of the sphere of the self in adoption, but few efforts have been made to better understand the role played by farmers’ perceptions in the formation of their thinking about innovative tools. This work aims to deepen the sphere of the self and, in particular, the role played by farmers’ perceptions when faced with the innovation adoption choice. The study presents a new conceptual framework identifying key stages for analysing adoption processes, focusing on the relationships between behaviour, structural dimensions and adoption, interpreted from the farmer perspective. The Q methodology (QM) was used with a targeted sample of 23 farmers to identify prevailing discourses. In the first step, the socio-structural dimensions were analysed through descriptive analysis, and in the second step, the discourses were extracted by an intercorrelation matrix through the centroid procedure, translating the solution using varimax rotation. This paper highlights that the QM is an appropriate technique for exploring and studying farmers’ attitudes when challenged with innovation. The results reveal discourses that summarise three macro perspectives: the “proactive approach”, which represents farmers who perceive PF as having a key role for agricultural enterprises; the “conservative approach”, which characterises those who distrust innovations; and the “doubtful approach”, which is the more sceptical vision

PEGASO: Polar Explorer for Geomagnetic And other Scientific Observation

PEGASO (Polar Explorer for Geomagnetic And other Scientific Observation) program has been created to conduct small experiments in as many disciplines on-board of small stratospheric balloons. PEGASO uses the very low expensive pathfinder balloons. Stratospheric pathfinders are small balloons commonly used to explore the atmospheric circumpolar upper winds and to predict the trajectory for big LDBs (Long Duration Balloons). Installing scientific instruments on pathfinder and using solar energy to power supply the system, we have the opportunity to explorer the Polar Regions, during the polar summer, following circular trajectory. These stratospheric small payload have flown for 14 up to 40 days, measuring the magnetic field of polar region, by means of 3-axis-fluxgate magnetometer. PEGASO payload uses IRIDIUM satellite telemetry (TM). A ground station communicates with one or more payloads to download scientific and house-keeping data and to send commands for ballast releasing, for system resetting and for operating on the separator system at the flight end. The PEGASO missions have been performed from the Svalbard islands with the logistic collaboration of the Andoya Rocket Range and from the Antarctic Italian base. Continuous trajectory predictions, elaborated by Institute of Information Science and Technology (ISTI-CNR), were necessary for the flight safety requirements in the north hemisphere. This light payloads (<10 Kg) are realized by the cooperation between the INGV and the Physics department “La Sapienza” University and it has operated five times in polar areas with the sponsorship of Italian Antarctic Program (PNRA), Italian Space Agency (ASI). This paper summarizes important results about stratospheric missions.PNRA, ASI.Published940-9455IT. Osservazioni satellitariN/A or not JCRope

Pegaso: an ultra-light long duration stratospheric payload for polar regions flights

Stratospheric balloons are powerful and affordable tools for a wide spectrum of scientific investigations that are carried out at the stratosphere level. They are less expensive compared to satellite projects and have the capability to lift payloads from a few kilograms to a couple of tons or more, well above the troposphere, for more than a month. Another interesting feature of these balloons, which is not viable in satellites, is the short turnaround time, which enables frequent flights. We introduce the PEGASO (Polar Explorer for Geomagnetism And other Scientific Observations) project, a stratospheric payload designed and developed by the INGV (Istituto Nazionale di Geofisica e Vulcanologia), Rome and La Sapienza University, Rome. The project was sponsored by the PNRA (Progetto Nazionale di Ricerche in Antartide), Italy (Peterzen et al., 2003). This light payload (10 kg) was used by the Italian Space Agency (ASI) and Andoya Rocket Range (ARR) for five different scientific missions. PEGASO carries a 3-component flux-gate magnetometer, uses a solar cell array as the power source and has a GPS location system.

Pegaso: an ultra-light long duration stratospheric

Launched from the Mario Zuccelli Station (Baia Terra Nova) in Antarctica during the 2005/06 austral summer, the PEGASO-D payload lifted into the stratospheric anticyclone over the southern polar region. This effort marks the first Long Duration Scientific payload to be launched from this location and is the fourth such payload launched in the polar regions. Performing in the framework of the NOBILE/AMUNDSEN collaborative LDB development between ASI-ARR. The Italian Institute of Geophysics and Volcanology (INGV), with the sponsorship of the Italian Antarctic Program (PNRA) and the Italian Space Agency (ASI),designed and built the Ultra-Light system together with three Universities in Italy. The Pegaso program has been created to investigate the Earth magnetic field and provide a precursor series of small payload launches for the bigger LDB program such as OLIMPO, BOOMERanG and BArSPOrt through this collaboration between ASI and ARR. The Italian scientific community, aware of the big advantages that LDB balloons can offer to their experiments, proposed to extend the LDB program to Southern polar regions, besides performing launches from the newly initiated Nobile/Amundsen Stratospheric Balloon Center in Svalbard, Norway.Three PEGASO (Polar Explorer for Geomagnetics And other Scientific Observations) payloads have been launched from the Svalbard (No) in collaboration with Andoya Rocket Range, ASI and ISTAR (Operations and logistics) during the past two northern summers. These stratospheric (altitude m.35000) small 10kmc balloons have floated in the stratosphere between 14 to 39 days measuring the magnetic field of polar regions, by means of a 3-axys-fluxgate magnetometer, during a three year campaign. The study of the magnetic field and its variations is done through permanent observatories. They provide us with high quality data but their spatial distribution is not quite regular, specially in Antarctica due to logistic difficulties. The coverage is improved through marine and aeromagnetic surveys, and also through satellite missions. There exists nevertheless a gap in the wavelengths of the magnetic field represented by these kind of measurements. Satellite data are too far away from Earth's surface to individuate wavelengths lower than 1000 km, and near-ground sur- veys are not able to represent wavelengths longer than the dimensions of the surveyed area. Moreover, there is a region empty of data around the geographical pole for the satellite measurements. The size of these gaps depends on the orbital parameters, but it can reach up to 10 degrees around the pole. PEGASO allows to bridge this gap in the measurements of the magnetic field. Surveys carried out at 35 km height allow the study of crustal anomalies in the range between, we can say, 60 and 1000 km. Taking into account that pathfinders (smaller non-recoverable balloon systems) are usually sent to explore the atmospheric currents, the use of PEGASO as pathfinder allows us to obtain all these results at a very affordable cost. The PEGASO payload was also developed as a single source system integrating science, housekeeping and operational control of the entire balloon borne configuration.Satellite telemetry sent the scientific (magnetometric) data, house-keeping (temperature, solar panel voltage and current, altitude and time) and telecommand (four ballast, two parachute release system, system reset), and powered the terminate system. Data flows through the IRIDIUM telephone service. The onboard systems were kept inside a vessel (white painted and pressurizzed vessel due to power dissipation) except for external flexible solar panels and magnetometer, attached to an external boom. Two redundant tracking systems have been used: a first GPS was integrated inside the on-board telemetry system, necessary to reconstruct position and time of scientific data, while an independent GPS-ARGOS system gave the balloon trajectory, including its descent. Continuous trajectory predictions were made during the missions; they have been necessary, in particular, for the flight safety requirements of the northern hemisphere. The evaluation of the statistical error is proposed. The PEGASO payload was developed to be a light, cost effective way to explore the potential of Ultra-Light Long Duration Ballooning for science as well as an introduction to the earth-space possibilities for students.PublishedBeijing, China1A.
