Dynamics of structural change in agriculture, transaction cost theory and market efficiency: The case of cultivation contracts between agricultural e…

2022

In developed economies, the increasing openness of markets, the ease of trade and the speed of information lead to territorial imbalance and marginalization phenomena of small agricultural activities that cannot compete with the new models of agri-food systems. In this research, starting from this situation, we analyze through the Transaction Cost Theory what can be practised too recover competitiveness margins for small farms. From the study, it emerges that cultivation contracts represent a valid tool for the solution of various marginalization problems of many agricultural enterprises. In particular, from the experience gained over the past few years in Sicily, the cultivation contract b…

Identifikasi Telur Cacing pada Saluran Pencernaan Satwa Liar yang Dipelihara Masyarakat di Manokwari, Papua Barat

2021

Investment of parasitic worms of captive wildlife was an impact on their health condition. This study was conducted to determine the intensity of parasitic worm infection in wild animals kept by communities in Manokwari, West Papua. The Natif method was used, by centrifuge of 20 birds and 20 mammals (Kangaroo and Deer) faeces collected from the sites. Sampling was carried out from October to November 2016. The analysis of collected faecal samples showed that bird species were not indicated (negatively infected by worm). In mammals, Nematodes and cestodes were found. Identification of existing findings showed that 3 (three) types of worm eggs were found, namely Taenia sp in kangaroos (Macrop…

Schweigen in Videokonferenzen: Vom Umgang mit Störungen in Online-Besprechungen

2020

This paper deals with silence in video-based discourse, which includes pauses and delays. The data of the study is provided by international video conferences in which six in-service teachers and six pre-service teachers from three countries (Italy, the Netherlands, Hungary) together with a moderator and an assistent discuss sequences of their lessons. These discussions are part of a teacher training progrmme as conceived and implemented in the Erasmus+ project LEELU (www.leelu.eu). The focus of the present study is to analyse through a multimodal approach how the above-mentioned moments of silence co-constitute the video-based interaction, and how the discourse is built up with the other m…

Is Green Harvesting a Useful Instrument to solve Market Problems in the Wine Sector? Some Lessons from Sicily

2016

The green harvesting (GH) policy measure has been introduced in Italy starting from the 2009/2010 wine season, with the goal of preventing market crises by reducing the yield of a given parcel to zero. In the 2010-2012 period, almost 85% of the national expenditure and about 81% of European Union (EU) expenditure for this measure have been showered on Sicily. This paper, after examining the application of GH in this Region, explores the motivations of 300 vine growers of Western Sicily for taking part, or refusing to do so, in the GH measure. The survey shows the contrasting nature of the opinions that the implementation of GH has caused among the interviewed sample. In fact, on the one han…

Il ruolo del settore vitivinicolo nei processi di sviluppo sostenibile: il caso di Pantelleria

2008

La Sicilia è senza dubbio una delle principali regioni vitivinicole italiane, sia per la qualità delle sue produzioni che per la quantità di vino prodotto che ancora oggi, nonostante le 7 IGT e le 22 DOC presenti nel territorio, viene però solo in minima parte confezionato e commercializzato sui mercati finali del dettaglio tradizionale. Tra le denominazioni di origine, una tra le più antiche che si sta negli ultimi anni affermando sempre più sul mercato nazionale e straniero è il passito di Pantelleria. Questo vino dolce da dessert, prodotto nell’omonima isola esclusivamente dalla cultivar zibibbo, nonostante sia tutelato dalla denominazione già dai primi anni ’70 non è mai riuscito ad eme…

Main intrinsic factors driving land grabbing in the African countries’ agro-food industry

2022

Land grabbing is a phenomenon that has spread widely over the last two decades and which involves rich and emerging countries and international companies as protagonists in the large-scale acquisition of land in developing countries. Through the development of an econometric model that takes into account the annual size of land grabbing in the African countries, the research aims to understand the main intrinsic factors, linked to the hosting countries, that guide the large-scale acquisition of land by foreign investors. Results show that the presence of a high debt towards foreign organisations, the high availability of virgin lands, the strong vocation of the hosting country for the culti…

Task-based visual analytics for interactive multiobjective optimization

2020

We study how visual interaction techniques considered in visual analytics can be utilized when implementing interactive multiobjective optimization methods, where a decision maker iteratively participates in the solution process. We want to benefit from previous research and avoid re-inventing ideas. Our aim is to widen awareness and increase the applicability of interactive methods for solving real-world problems. As a concrete approach, we introduce seven high-level tasks that are relevant for interactive methods. These high-level tasks are based on low-level tasks proposed in the visual analytics literature. In addition, we give an example on how the high-level tasks can be implemented a…

Visualizations for Decision Support in Scenario-based Multiobjective Optimization

2021

Reproducibility artifacts for: Babooshka Shavazipour, Manuel López-Ibáñez, and Kaisa Miettinen. Visualizations for Decision Support in Scenario-based Multiobjective Optimization. Information Sciences, 2021. doi:10.1016/j.ins.2021.07.025. Abstract: We address challenges of decision problems when managers need to optimize several conflicting objectives simultaneously under uncertainty. We propose visualization tools to support the solution of such scenario-based multiobjective optimization problems. Suitable graphical visualizations are necessary to support managers in understanding, evaluating, and comparing the performances of management decisions according to all objec…

La promoción de la imagen política en Instagram: un estudio del perfil personal de Santiago Abascal (Vox) en 2018

2020

Due to Instagram’s growing popularity in Spain, politicians have also begun to turn to this social network increasingly more. Accordingly, this paper analyses the visual and textual discourse of 259 posts published throughout 2018 on the personal Instagram profile of Santiago Abascal, the leader of the party Vox. Insofar as he is the Spanish politician with the highest number of followers on Instagram, the aim here is to analyse how he uses this social network in order to identify possible strategies that justify his growing number of followers. In the analysis, special attention was paid to aspects that might have contributed to the (self)presentation of Abascal and the promotion of his pa…
