In certain contexts, dairy firms are supplied by small-scale family farms. Firms provide a set of technical and economic recommendations meant to help farmers meet their requirements in terms of the quantity and quality of milk collected. This study analyzes how such recommendations may be adopted by studying six farms in Brazil. All farms are beneficiaries of the country's agrarian reforms, but they differ in terms of how they developed their activities, their resources and their milk collection objectives. First, we built a technical and economic benchmark farm based on recommendations from a dairy firm and farmer advisory institutions. Our analysis of the farms’ practices and technical and economic results show that none of the farms in the sample apply all of the benchmark recommendations; however, all farms specialized in dairy production observe the main underlying principles with regard to feeding systems and breeding. The decisive factors in whether the benchmark is adopted and successfully implemented are (i) access to the supply chain when a farmer establishes his activity, (ii) a grasp of reproduction and forage production techniques and (iii) an understanding of dairy cattle feed dietary rationing principles. The technical problems observed in some cases impact the farms’ dairy performance and cash position; this can lead to a process of disinvestment. This dynamic of farms facing production standards suggests that the diversity of specialized livestock farmers should be taken into account more effectively through advisory approaches that combine basic zootechnical training with assistance in planning farm activities over the short and medium term.
Most information systems that deal with natural language texts do not tolerate much
deviation from their idealized and simplified model of language. Spoken dialog is notoriously
ungrammatical, however. Because the MAREDI project focuses in particular on the automatic
analysis of scripted dialogs, we needed to develop a robust capacity to analyze transcribed
spoken language. This paper summarizes the current state of our work. It presents the main
elements of our approach, which is based on exploiting surface markers as the best route to the
semantics of the conversation modelled. We highlight the foundations of our particular
conversational model, and give an overview of the MAREDI system. We then discuss its three key
modules, a connectionist network to recognise speech acts, a robust syntactic analyzer, and a
An accurate modelling and simulation of the sublimation growth process needs a software taking into account a multitude of highly coupled phenomena: fluid mechanics, convective, conductive and radiative heat transfer, electromagnetic, multicomponent species transport, homogeneous and heterogeneous reactivity and finally thermal and transport databases. The objective of this paper is to combine modelling trends with experimental results to propose explanations and solutions to growth problems. Finally, a simple and generic mechanical approach will show the relations between the density of dislocations and the temperature field.
Researchers and industry are actively developing Software Agents
that will assist users in achieving various tasks, collaborate with them,
even act on their
behalf. To explore new interaction modes for SAs which need to be more
simple exchanges of messages, we have analysed human conversations and
interaction approach for SAs based on a conversation model. Using this
approach, we have
developed a multi-agent system that simulates conversations involving SAs.
We assume that
SAs perform communicative acts to negotiate about mental states, such as
beliefs and goals,
turn-taking and special conversational sequences. We also assume that SAs
communication protocols when they negotiate. In this paper,
we describe the conceptual
structure of communicative acts, the knowledge structures used to
model a conversation, and
the communication protocols. We show how an inference engine using
‘conversation-managing rules’ can be integrated in a conversational
agent responsible for interpreting
communicative acts, and we discuss the different kinds of rules that we
propose. The prototype
PSICO was implemented to simulate conversations on a computer platform.
Facial motor function was assessed in 61 patients 18 months after surgical resection, by the translabyrinthine approach, of vestibular schwannoma involving both the cerebellopontine angle (CPA) and the auditory canal.
Pre-operative magnetic resonance imaging (MRI) was performed to measure the maximum extracanalicular diameter of the tumour between the porus and the farthest extension in the CPA on tranverse slices and to calculate extracanalicular tumour volume. Post-operative facial motor function was graded according to the House and Brackmann system.
There was a statistically significant relationship between late facial motor function and extracanalicular diameter. The best cut-off point for good and poor results was 20mm. There was no relationship between the tumour volume and the late post-operative facial motor function grade.
In this study the best pre-operative radiological predictor of the late facial motor function in patients operated on by the translabyrinthine approach was the maximum diameter measured byMRI.
