Design, Implementation, and Evaluation of a Virtual Meeting Tool-Based Innovation for UML Technology Training in Global Organizations
2012
End-user training is complicated to implement in global corporations whose activities are typically scattered across multiple sites in different countries and leverage information systems in various ways. This is especially true in global software development where the sites may leverage a development tool for totally different purposes. Web-based Virtual Meeting Tools (VMT) enable synchronous communication globally through interactive audio, online chats, video, and the sharing of presentations. They provide potentially a cost effective way to train even complex topics to large numbers of people in global settings. Few industrial experiences from the design and use of VMT-based training in…
Empowering leadership, mindful organizing and safety performance in a nuclear power plant: A multilevel structural equation model
2020
Abstract The aim of this paper is to develop and test a model in which empowering leadership is expected to contribute to developing mindful organizing, which in turn should contribute to safety compliance and safety participation. Empowering leadership was measured at Time 1, and the rest of the variables were measured two years later (Time 2). The sample used for the analyses in this study included 49 teams and 200 employees from a company in the nuclear generation industry with three different sites. The multilevel structural equation analysis performed to test the proposed model revealed an acceptable fit, and most of the paths were statistically significant and presented the expected s…
RgbDF: Resource Goal and Behaviour Description Framework
2006
Agent-oriented approach has proven to be very efficient in engineering complex distributed software environments with dynamically changing conditions. The efficiency of underlying modelling framework for this domain is undoubtedly of a crucial importance. Currently, a model-driven architecture has been the most popular and developed for purposes of modelling different aspects of multi-agent systems, including behaviour of individual agents. UML is utilized as a basis for this modelling approach and variety of existing UML-based modelling tools after slight extension are reused. This paper proposes an ontology-driven approach to modelling agent behaviour as an emerging paradigm that originat…
USE OF GAMIFICATION IN HUMAN RESOURCE MANAGEMENT: IMPACT ON ENGAGEMENT AND SATISFACTION
2018
The use of games, also called gamification, is innovative an approach in contemporary human resource management. The aim of this research is to assess whether gamification, if used in HR processes, can increase engagement and job satisfaction among employees, as well as to identify which HR processes respond better to gamification. Using data from CAWI interviews (n = 620) and Structural Equation Modelling (PLS-SEM) method with smartPLS software, the researchers found a significant positive impact of gamification on employee job satisfaction, however, no impact on engagement. Teambuilding and internal communication were identified as HR processes which better respond to gamification and rec…
Organisational learning capability, product innovation performance and export intensity
2012
The hypothesis that managerial characteristics which facilitate the organisational learning process can provide firms with a basis for competitive advantage has received a great deal of attention. While there is evidence that organisational learning affects export intensity, we argue that intermediate variables, such as innovation, should be used in order to evaluate its impact in organisations. This study shows that firms with a higher organisational learning capability tend to be more innovative, and for this reason, they are more likely to export a higher share of their production. From a longitudinal perspective, we use structural equation modeling on a database from Italian and Spanish…
Knowledge management and innovation performance in a high-tech SMEs industry
2011
This article examines how knowledge management (KM) affects innovation performance within biotechnology firms. This is an industry in which small- and medium-sized biotech enterprises live together with the biotech divisions of large pharmaceutical firms. We conceptualize KM as a set of practices and dynamic capabilities, and hypothesize that KM dynamic capabilities act as a mediating variable between KM practices and innovation performance. We use structural equation modelling to test the hypotheses on a data set from the biotechnology industry. The results support our conceptualization and demonstrate its utility in explaining differences in innovation performance across firms. Findings …
Human Resources Management Practices Perception and Extra-Role Behaviors: The Role of Employability and Learning at Work
2021
Human Resource Management (HRM) processes are considered the beating heart of any successful organization. Recently, several studies have highlighted how organizations can use commitment-oriented HR practices to generate organizational and individual effectiveness. The aim of this study was to verify whether the perception of HRM practices could be able to elicit extra-role behaviors and, at the same time, whether this relationship could be mediated by employability and learning conditions. The analyses were carried out on a sample of 1219 Italian workers using Structural Equation Models. The structural model yielded good fit indices and the results showed a significant and positive effect …
XML Enabled Metamodeling and Tools for Cooperative Information Systems
2001
The development of tools to support semantic resolution is a key issue in the design of heterogeneous interoperable information systems. This paper presents a methodology and a data model translator toolkit, called X-TIME, for the design and management of interoperable information systems. X-TIME combines a metamodelling approach and XML features to provide support for automated design of wrappers or semantic reconciliators. It is a flexible semantics oriented approach that takes into account several important characteristics of interoperable information systems, including extensibility and composability. Extensibility requires a translation scheme that can easily integrate new data models.…
Il Portico meridionale della Cattedrale di Palermo: sperimentazioni di rilievo attraverso l’utilizzo di tecniche Structure from Motion
2014
Structure from Motion (SfM) techniques constitute a very fertile field of investigation within the research of the surveying sector and that of the representation of architecture. They allow us to reach higher levels of reliability and accuracy, both metric and graphical, extremely quickly and with lower costs than other methods, including the laser scanner. In this study, we report the results of some experiments carried out on the southern Portico entrance of the Cathedral of Palermo through the use of the SfM techniques later validated by comparison with the point cloud obtained from laser scanning.
Supervised vs Unsupervised Latent DirichletAllocation: topic detection in lyrics.
2020
Topic modeling is a type of statistical modeling for discovering the abstract ``topics'' that occur in a collection of documents. Latent Dirichlet Allocation (LDA) is an example of topic model and is used to classify text in a document to a particular topic. It builds a fixed number of topics starting from words in each document modeled according to a Dirichlet distribution. In this work we are going to apply LDA to a set of songs from four famous Italian songwriters and split them into topics. This work studies the use of themes in lyrics using statistical analysis to detect topics. Aim of the work is to underline the main limits of the standard unsupervised LDA and to propose a supervised…
