Exploring relationship variables and Information and Communication Technologies use in industrial segmentation
2017
Purpose In tourism, the adoption of Information and Communication Technologies (hereinafter ICT) and variables concerning firms’ links with suppliers have been recognized as key determinants to improve companies’ competitiveness. From the perspective of efficient management of company resources, segmentation has become a key tool and is particularly significant and current in the business-to-business context. The purpose of this paper is to study the segmentation of firms in the tourist industry according to perceived ICT use and relationship value and benefits. In addition, from the management approach, the authors seek to describe the segments that enable the development of differentiate…
Media constructions of fear in the outbreak of an epidemic disease
2016
Purpose – After almost a decade, the re-appearance of dengue fever in Argentina caused panic and fears. Unlike Bolivia, Brazil and Paraguay, where prevention policies have been followed, the future of dengue is uncertain in Argentina; the present paper does not have political affiliation but the purpose of this paper is to emphasizes the role that mass media plays in the coverage of epidemics. Design/methodology/approach – In moments of disorder, uncertainness or disaster, societies experience a shift in the ways they perceive their reality. Findings – In the times, media plays a dominant role in constructing the reality that the authors get to consume. Such reality is reflective of media’…
An Empirical Research on the Impacts of organisational decisions’ locus, tasks structure rules, knowledge, and IT function’s value on ERP system succ…
2014
This research examined the impacts of organisational decisions’ locus, tasks structure, rules and procedures, organisational actors’ information technology (IT) skills/knowledge and IT department’s or function’s value perceptions on enterprise resource planning (ERP) system success. While such antecedent factors matter in the discourse, research on their impacts on ERP success is rare. To increase understanding in the area, we proposed a research model and developed pertinent hypotheses that included the above-mentioned factors. Using a cross-sectional field survey, we collected data from 165 firms in three European countries. Data analysis was performed using the partial least squares (PLS…
Post-entry internationalisation activity of retailers
2013
Purpose – The purpose of this paper is to propose a framework, based on empirical research, to explain the strategic processes of post-entry development in international retailing through consideration of the dynamic capabilities attributable to retailers. Design/methodology/approach – Case study approach of five international retail firms using secondary data and primary data gathered through interviews with firms ' executives and financial analysts. Findings – The research findings, in the light of the existing literature, suggest a framework that makes a distinction between first level or generic dynamic capabilities relevant to the internationalization process and second level or speci…
Higher education and the development of competencies for innovation in the workplace
2012
PurposeThis paper aims to analyze the production function nexus between higher education practice and the development of innovation‐related competencies by university graduates in Spain. The research hypothesis is the presence of statistically significant relationships between the development of innovational competencies and the modes of teaching and learning used in higher education practice.Design/methodology/approachThe relationships are modeled through a set of stochastic frontier and variance component equations with the development of each competency as the dependent variable. The main explanatory variables capture the prevalence of diverse teaching/learning modes and the behavior of …
A Spatial Difference-in-Differences Estimator to Evaluate the Effect of Change in Public Mass Transit Systems on House Prices
2014
Evaluating the impact of public mass transit systems on real-estate values is an important application of the hedonic price model (HPM). Recently, a mathematical transformation of this approach has been proposed to account for the potential omission of latent spatial variables that may overestimate the impact of accessibility to mass transit systems on values. The development of a Difference-in-Differences (DID) estimator, based on the repeat-sales approach, is a move in the right direction. However, such an estimator neglects the possibility that specification of the price equation may follow a spatial autoregressive process with respect to the dependent variable. The objective of this pap…
A graph colouring model for assigning a heterogeneous workforce to a given schedule
1996
Abstract We analyze a heterogeneous workforce assignment problem in which the minimum number of workers required to carry out a machine load plan is calculated. The problem is formulated as a restricted vertex colouring problem and a branch and bound algorithm is presented. The special characteristics of the graph to be coloured allow an efficient implementation of the branch and bound. Computational results show that the algorithm can solve problems of 50 activities, 5, 10 and 15 machines and between 2 to 15 different types of workers in just a few seconds.
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…
Communication in new technology based‐firms
2013
PurposeThe paper aims at identifying the main social media applications used by new technology based‐firms (NTBFs) and at calculating the volume of followers they have in each application. It also focuses on the amount of activity generated by the firms in those social networks, identifying the key thematic content of their social media activity, analyzing the ability to create dialogue with their stakeholders and clarifying which style of communication they use.Design/methodology/approachThe paper presents an exploratory study of the use of social media tools by NTBFs, located in Spanish Science Parks, as an important resource network for firms in the corresponding sector. A total of 432 n…
Context DataModel Framework: semantic facilities management
2008
Facility management is the practice of coordinating the physical workplace with the people and work of the organisation. It integrates the principles of business administration, architecture and the behavioural and engineering sciences. Software dedicated to facility management are usually limited to spreadsheet software. With the development of the Industry Foundation Class (IFC; a new object-oriented standard to model buildings) and web-based networks, a new generation of methods and tools dedicated to facility management are required. To deal with these requirements, we have developed a framework based on Semantic Web technologies: RDF, Ontology Web Language (OWL), Semantic Web Rule Lang…
