Improving operation of a complex headworks system for municipal use and hydropower production by mathematical programming

2013

The paper presents a Mixed Integer Non Linear Programming (MINLP) model of the water resources system supplying Genoa, in northern Italy. The system presently features five reservoirs, three main river intakes, and two well fields. The hydrological regime is typically Mediterranean; water availability is however relatively abundant, so that drought issues are limited, especially now that water demand from the supply sources has decreased due to reduced population, deindustrialization and to improvement in the operation and maintenance of the water distribution network. In this context, it is worthwhile considering the possibility to relax an over-conservative management of resources, justif…

Managing electrical energy storage systems and shiftable loads with an innovative approach in energy districts

2014

In this work, a power dispatch problem for a system composed of an aggregate of loads and an electrical energy storage system is considered. The approach to solve the optimal dispatch is innovative and shows good performances in limited calculation times. According to the more recent indications coming from the European distributors, the architecture for energy dispatch at distribution level will be hierarchical. The 'Aggregator' is the interface between groups of loads and the energy distributor and sends the individual consumers the desired load profiles, following which the user may gets a discount on the energy bill. On the other hand, the energy tariff may follow a given daily profile …

Real-time pricing for aggregates energy resources in the Italian energy market

2015

Abstract Over the last decade, the architecture of the energy market has radically changed. In many countries end-users are now able to directly access the market, which has given rise to the question of how they can actively participate in that market. End-users can comprise a critical mass through aggregation that is carried out by a third party – to wit the “loads aggregator.” This paper proposes a new framework for generating feasible real-time price curves for those end-users in a demand-response management process. The underlying algorithm generates output curves as the solution to a constrained optimization problem whose objective function is the aggregator's economic benefit. A case…

Corporate entrepreneurship and human resource management: theoretical background and a case study

2011

Purpose: This article aims to review varying concepts of entrepreneurship and different contributions to human resource practices, establishing a theoretical framework that allows for the analysis of the firm Montalt-Valencia (Spain), a Ford-Spain car dealer, and leader in its sector. Design/methodology/approach: The paper, according to the literature, establishes a theoretical framework on entrepreneurship and human resource management through which one can observe and research the Montalt-Valencia case study. The case study is confirmatory, from the theoretical background, and at the same time inductive from the observation of its non-expected details and deeds. Findings: The firm Montalt…

Self-organised structures in the field of ICT : challenges for employees’ workplace learning

2021

PurposeThe purpose of this study is to identify the challenges of low hierarchy and self-organised structures for employees’ learning and competency development at work. In the past decade, interest in employees’ and organisations’ self-directedness has increased. Self-organised structures are perceived as better able to answer to the quickly changing requirements of clients and business environments. Within these structures, employees are expected to take on more responsibility and maintain more control over their workplace learning, which means they must be self-directed and autonomous. An important question for this approach is how can workplace learning and employee competence developme…

An entrepreneur's social capital and performance: the role of access to information in the Argentinean case

2012

Purpose - The aim of this paper is to analyze the impact of an entrepreneur's social capital on their access to information, and how such access improves the performance of their entrepreneurial project. Design/methodology/approach - A structural equations model (SEM) is estimated and validated from a database including information from 282 Argentinean entrepreneurs who answered a questionnaire specifically designed for this research. The analysis of this model allowed the impact of dependent latent variables on the performance of the start-up to be determined. Findings - The performance of an entrepreneurial project depends on an entrepreneur's access to finance, markets and information. S…

Human resource development practices supporting creativity in Finnish growth organizations

2020

Creativity can be enhanced through appropriate Human Resource Development (HRD) practices that support employees’ learning and competence development. The aim of this study is to increase our understanding of HRD practices that enhance creativity in Finnish growth companies. To achieve this aim, we searched for creativity requirements based on employees’ experiences expressed in interviews, and we studied HRD practices used in organizations that respond to the requirements of creativity. We gathered 98 interviews from personnel in technology, industrial and artistic design organizations and utilized them for a theory‐driven content analysis to identify the variety of requirements for creati…

Cultural intelligence, global mindset, and cross-cultural competencies: a systematic review using bibliometric methods

2020

We conducted a systematic review of 158 publications on Cultural Intelligence (CQ) and related concepts, Global Mindset (GM), and Crosscultural Competence (CC) using bibliometric methods. We apply citation analysis to highlight the most influential (in terms of citations) journals, publications, and specific researchers in the field. We apply factor and cluster analyses to analyse co-citations to identify the current knowledge structure in the research field. With content coding on the resulting groups of co-citations, we identify five research streams showing the overlap between the CQ, GM, and CC constructs, and also revealing the separations in the research on the constructs. We perform …

An Emergent Taxonomy of Public Personnel Management: Exploring the Task Environment of Human Resource Managers in Spanish Local Government

2018

This study presents a taxonomy for public personnel management based on emergent profiles of local human resource managers in Spain. The analysis focuses on the task environments of managers defined by three salient constructs from strategic human resources management research. Specifically, this study looks at the level of participation of human resource managers in strategic-level policy-making processes, vertical and horizontal policy integration, and the flexibility of human resource managers in interpreting and implementing key functions of personnel management (i.e., recruitment, hiring, and remuneration). The results yield five distinct profiles that describe different approaches of…
