Attitudes towards Italian wine of practitioners in the Chinese distribution

China’s economy has grown at an impressive rate after the integration into the global trading system (WTO) in 2001, a major turning point in the Chinese economic history. The opening policy has increased business opportunities for both local and foreign operators; however, in spite of the great appeal of such cooperation, many obstacles yet exist: language, culture, education, business practices, and industrial development. Food products supply and access to the market are mastered by a relatively small group of businessmen: international buyers, purchasing agents, retailers and representatives of large-scale distribution chains. The perception they have of a potential source country is a key factor for a successful market approach. The present study aims at understanding the attitudes of distribution practitioners in the Chinese market towards imported Italian quality wine, as well as the current communication, marketing, strategic and organizational advantages or deficiencies of Italian producers, compared to other European counterparts. The primary data were collected through personal interviews with key informants in Shanghai, Beijing and Guangzhou. Such information has been completed with an analysis of the existing literature, meetings with sector operators as well as with talks and presentations of experts attending the “International Workshop on Chinese Wine Market”, held in Beijing on August 8-10, 2007. The interviews have been administered as conversation-like dialogues, on the base of a semi-structured interview outline, providing also the framework for a qualitative content analysis. This paper is aimed at giving an insight on import and distribution of Italian wine in China, highlighting both positive and negative feedbacks on the effectiveness of marketing strategies of Italian wine trading companies.wine, international trade, distribution, China, "Made in Italy"

Online Safety Property Collection and Refinement for Safe Deep Reinforcement Learning in Mapless Navigation

Safety is essential for deploying Deep Reinforcement Learning (DRL) algorithms in real-world scenarios. Recently, verification approaches have been proposed to allow quantifying the number of violations of a DRL policy over input-output relationships, called properties. However, such properties are hard-coded and require task-level knowledge, making their application intractable in challenging safety-critical tasks. To this end, we introduce the Collection and Refinement of Online Properties (CROP) framework to design properties at training time. CROP employs a cost signal to identify unsafe interactions and use them to shape safety properties. Hence, we propose a refinement strategy to combine properties that model similar unsafe interactions. Our evaluation compares the benefits of computing the number of violations using standard hard-coded properties and the ones generated with CROP. We evaluate our approach in several robotic mapless navigation tasks and demonstrate that the violation metric computed with CROP allows higher returns and lower violations over previous Safe DRL approaches.Comment: Accepted at the 2023 IEEE International Conference on Robotics and Automation (ICRA).

Partially Observable Monte Carlo Planning with state variable constraints for mobile robot navigation

Autonomous mobile robots employed in industrial applications often operate in complex and uncertain environments. In this paper we propose an approach based on an extension of Partially Observable Monte Carlo Planning (POMCP) for robot velocity regulation in industrial-like environments characterized by uncertain motion difficulties. The velocity selected by POMCP is used by a standard engine controller which deals with path planning. This two-layer approach allows POMCP to exploit prior knowledge on the relationships between task similarities to improve performance in terms of time spent to traverse a path with obstacles. We also propose three measures to support human-understanding of the strategy used by POMCP to improve the performance. The overall architecture is tested on a Turtlebot3 in two environments, a rectangular path and a realistic production line in a research lab. Tests performed on a C++ simulator confirm the capability of the proposed approach to profitably use prior knowledge, achieving a performance improvement from 0.7% to 3.1% depending on the complexity of the path. Experiments on a Unity simulator show that the proposed two-layer approach outperforms also single-layer approaches based only on the engine controller (i.e., without the POMCP layer). In this case the performance improvement is up to 37% comparing to a state-of-the-art deep reinforcement learning engine controller, and up to 51% comparing to the standard ROS engine controller. Finally, experiments in a real-world testing arena confirm the possibility to run the approach on real robots

Psychological Profile and Quality of Life of Morbid Obese Patients Attending a Cognitive Behavioural Program

The results show that 27% of cases had a BES score ≥ 17, indicative of possible binge eating, and 13% had a BES ≥ 27, largely indicative of binge eating, with a higher prevalence in females. The BDI score was above normal in 30% of males and 45% of females, and 13% of females were in the range of moderate-severe depression. BES and BDI were significantly correlated with each other. Orwell-97 was much higher in females, and similarly the generic PGWB was indicative of a poorer HRQL in females. PGWB was positively associated with age, without any effect of BMI. The association with age was maintained in female, not in males. Both the Orwell-97 and the PGWB were associated with both BES and BDI in both genders. Psychological distress is common and largely variable in patients attending CBT for morbid obesity. This data should be considered for individual treatment protocols, and should be compared with similar series of patients enrolled for bariatric surger

Terrain visibility impact on the preparation of landslide inventories: a practical example in Darjeeling district (India)

Landslide inventories are used for multiple purposes including landscape characterisation and monitoring, and landslide susceptibility, hazard and risk evaluation. Their quality and completeness can depend on the data and the methods with which they were produced. In this work we evaluate the effects of a variable visibility of the territory to map on the spatial distribution of the information collected in different landslide inventories prepared using different approaches in a study area. The method first classifies the territory in areas with different visibility levels from the paths (roads) used to map landslides and then estimates the landslide density reported in the inventories into the different visibility classes. Our results show that (1) the density of the information is strongly related to the visibility in inventories obtained through fieldwork, technical reports and/or newspapers, where landslides are under-sampled in low-visibility areas; and (2) the inventories obtained by photo interpretation of images suffer from a marked under-representation of small landslides close to roads or infrastructures. We maintain that the proposed procedure can be useful to evaluate the quality and completeness of landslide inventories and then properly orient their use.This research has been supported by the Natural Environment Research Council (grant no.

Interconnection Effects in Multiparticle Production from WW Events at LEP

Interactions between the products of the hadronic decays of different Ws in WW pair events can occur at several stages: from the colour rearrangement between the quarks coming from the primary branching, to the gluon exchange during the parton cascade, to the mixing of identical pions due to Bose-Einstein correlations. Besides the intrinsic interest of their study related to the understanding of the multiparticle production mechanisms, these phenomena can affect the ultimate accuracy in the W mass measurement by LEP 2. The status of the experimental analysis on interconnection effects between W pairs hadronically decaying is reviewed in this paper.Comment: 10 pages, 7 figures. To be published in Proc.

Palynological characterization of the Po delta succession (northern Italy): Holocene vegetation dynamics, stratigraphic patterns and palaeoclimate variability

The 40 m-long core EM2, recovered in the innermost portion of Po delta plain, was sampled for palynological analysis, in order to link coastal-deltaic facies architecture to vegetation dynamics and Holocene climate variability. Pollen data refine facies characterization of the 25 m-thick Holocene succession: freshwater swamp clays alternating with overbank/channel sands document millennial to centennial-scale water table oscillations that invariably peak in correspondence of peaty layers. Pollen signature allows identification of the landward equivalent of the Maximum Flooding Surface atop the 7.6 ka-dated peaty interval and furnishes new insights on the relationship between coastal facies patterns and climate events

Patient Opinions on the Helpfulness of External Rehabilitative Activities in Residential Psychiatric Care: A Pilot Study

INTRODUCTION: This study explores the patient opinions about the helpfulness of the External Rehabilitative Activities (ERA) delivered in two residential facilities for psychiatric rehabilitation. METHODS: We administered a Questionnaire developed to assess general helpfulness, helpfulness of specific therapeutic processes and satisfaction with the ERA to a sample of 46 psychiatric patients participating in at least three external activities. RESULTS: The External Rehabilitative Activities, tested by the ERA-Questionnaire, were considered helpful or very helpful by most of the patients. The therapeutic process with the highest score was "relaxation", followed by "general helpfulness", "socialization", "knowledge of social context", "community integration". The least-valued process was "autonomy". CONCLUSION: This pilot study has shown that psychiatric patients consider ERA helpful and rate more helpful the specific therapeutic processes, such as relaxation and socialization, that assure symptomatic relief and interaction with the outside world

Bulges and Disklike Components in the Host Galaxies of Low-Redshift 3CR Sources: A Near-Infrared View of Their Radial Brightness Profiles*

We analyze the near-infrared luminosity profiles and photometric parameters of the host galaxies of 3CR radio sources with z < 0.3, to investigate their physical nature. Our sample includes 82 galaxies, of which 22 (27%) are FR Is and 60 (73%) are FR IIs. Using near-infrared data taken both with NICMOS on board the Hubble Space Telescope and from the ground with the Telescopio Nazionale Galileo, we find that luminosity profiles are very well described by a single S?rsic law in 52% of the cases and that for the remaining objects (48%) it is necessary to include an exponential profile, which indicates the presence of a second disklike component. The average bulge-to-disklike components luminosity ratio for the galaxies is (b/e) ~ 1.1. The analysis of the photometric parameters of the subsamples indicates that FR Is and FR IIs show rather similar bulges in terms of effective surface magnitude, effective radius, and S?rsic index. On the other hand, the disklike components in FR I and FR II hosts show, on average, different properties. Central surface magnitudes are dimmer and scale lengths are greater by a factor of 2 in FR Is when compared to FR IIs. We also estimate the black hole mass associated with each galaxy using two different methods that claim tight correlations of the black hole mass (MBH) with the infrared bulge luminosity (Lbulge) and with the S?rsic index (n). Our data indicate that masses obtained through these two methods show a high dispersion and that MBH obtained through Lbulge are systematically higher (by a factor of ~3) than those obtained using n. This result may reflect the fact that for our sample galaxies we do not find any correlation between Lbulge and n
