Operational Intelligence and School Problems Measured by Piagetian Tasks and Rhode Island Pupil Identification Scale
1998
To explore the relations between operational intelligence rated on several Piagetian tasks and school learning problems identified by the Rhode Island Pupil Identification Scale by Novack, Bonaventura, and Merenda we assumed that Piagetian performances would allow predicting learning problems of first graders. 38 pupils were evaluated by three teachers, who were asked to complete the Rhode Island scale. Then the same children were individually given 8 Piagetian tests (including conservation and logical tasks) by an examiner who had no information about the pupils' other scores. Analysis showed that successful Piagetian performances were associated with ratings of successful schoolwork Anal…
Job seeker's spatial equilibrium in a fuzzy mathematical framework
1990
This paper incorporates complex behavior in a job seeking strategy model. Since the state of information is imperfect, a job seeker faces an imprecise labor market. His behavior is fuzzy and variable. It is shown how this complex behavior can be described by fuzzy subsets theory and bifurcation analysis. The latter examines the discontinuous phenomena. Then it is proved that a job seeker’s fuzzy equilibrium with a spatial constraint exists.
Dinamiche competitive dei principali prodotti ittici in Italia: possibili strategie di intervento
2011
Over the last few years, the Italian fishery sector has showed a tendential reduction in the economic performance because of the contraction of the value of the product, as a result of the fall in the catches and in the production average prices of the main species, and of the growing operational costs. Therefore, the contraction of the National supply is balanced by the imports which, in terms of value in the reference period tested in the current study (2003/04 – 2007/08) have grown, causing a further burdening in the absolute value of the Italian trade balance. The outlined background is made further worse by the slowdown, in few years, in the rise in the fishery products consumptions, d…
An Overview of 5G Slicing Operational Business Models for Internet of Vehicles, Maritime IoT Applications and Connectivity Solutions
2021
Identification of ecosystems and Business Models (BM) is an important starting point for new complex system development. The definition of actor (or stakeholder) roles and their interactions (at both business and technical levels), together with target scenarios and use cases, provide essential input information for further system requirement collection and architecture specification. The powerful and flexible Fifth Generation (5G) network slicing technology, which is capable of creating virtually isolated and logically parallel networks, enables a large range of complex services and vertical applications. Although various terminologies and models have been proposed in recent years for BMs …
Jason Intentional Learning: An Operational Semantics
2013
This paper introduces an operational semantics for defining Intentional Learning on Jason, the well known Java-based implementation of AgentSpeak(L). This semantics enables Jason to define agents capable of learning the reasons for adopting intentions based on their own experience. In this work, the use of the term Intentional Learning is strictly circumscribed to the practical rationality theory where plans are predefined and the target of the learning processes is to learn the reasons to adopt them as intentions. Top-Down Induction of Logical Decision Trees (TILDE) has proved to be a suitable mechanism for supporting learning on Jason: the first-order representation of TILDE is adequate t…
Improving the Crisis to Crisis Learning Process
2014
While crises may appear to be event-driven, post-mortem accounts often identify factors that accumulate over time and increase the likelihood of failure. These factors are particularly difficult to anticipate when multiple organizations are involved in crisis preparation and event detection. Through the development of a systems-based model of crisis management, it was learned that knowledge sharing can be accelerated or inhibited by the development of trust among organizations through the management of events. Is it possible to operationalize this finding? This hypothesis is one of the findings of the SEMPOC project, which examined crisis preparation and mitigation in the hypothetical conte…
From common operational picture to common situational understanding: An analysis based on practitioner perspectives
2021
Abstract The concepts of Situational Awareness (SA) and Common Operational Picture (COP) are closely related and well-acknowledged to be crucial factors for effective emergency management. In multi-agency operations, such as extreme weather events, the involved first responders manage the event with different mandates, objectives, and tools which can make it challenging to build a COP. Effective collaboration requires a common situational understanding, based on knowledge about each other’s responsibilities and tasks, mutual respect and trust, as well as common communication tools for emergency communication and information sharing. This paper argues that the COP serves as a basis for decid…
A consumer-based measurement of tourism innovation
2006
SUMMARY The present paper reviews the innovation literature related to tourism and examines the twin problems of operational definitions and measurement of innovation in the tourism sector. A conceptual model is then proposed by which the most relevant aspects of innovation and the most relevant aspects of the “tourism experience” can be integrated conceptually, and which can guide the development of related operational definitions and measurements and lead to a standardization of, and therefore an ability to aggregate, tourism innovation statistics across products, providers, markets and geopolitical regions. The model first categorizes innovations along two dimensions: an “invention-adopt…
Digital health technology enhances resilient behaviour: evidence from the ward
2019
PurposeIn the healthcare management domain, there is a lack of knowledge concerning the role of resilience practices in improving patient safety. The purpose of this paper is to understand the capabilities that enable healthcare resilience and how digital technologies can support these capabilities.Design/methodology/approachWithin- and cross-case research methodology was used to study resilience mechanisms and capabilities in healthcare and to understand how digital health technologies impact healthcare resilience. The authors analyze data from two Italian hospitals through the lens of the operational failure literature and anchor the findings to the theory of dynamic capabilities.Findings…
Social Entrepreneurship in Tanzania: Assessment of Enabling Environment
2009
The main purpose of the study was to assess the supporting environment for social entrepreneurship in Tanzania. Specifically, the study aimed at evaluating the current key stakeholders’ conceptualisation and recognition of Social Entrepreneurship concept and whether in Tanzania there is a supportive environment for Social Entrepreneurship. This was an exploratory study and was conducted qualitatively. The approach used was a combination of secondary data and in-depth interviews with policy makers and policy advisers. Findings revealed that most stakeholders are not aware of the concept of Social Entrepreneurship. The objectives of their organizations showed that they had some elements of So…
