From influencee to influencer : the rhizomatic target audience of the cyber domain
2015
The messages of an influence operation are interpreted in a variety of ways by their receivers. To increase the probability of success, these messages are typically tailored to affect a defined group, a target audience. Target audience analysis (TAA) is a process of finding suitable target audiences for influence operations. There are multiple ways of completing the task, ranging from fast and intuitive to complex multi-staged processes. These processes use the information available at the moment of making presumptions about the effectiveness of competing approaches in order to choose those with best end results. The internet presents a challenge to this type of sequential, linear process b…
Are quality management practices enough to improve process innovation?
2015
The popularity of quality management as a system for continuous improvement has not been accompanied by deep theoretical understanding of its effects on process innovation. In this work, the resource-based view serves as the basis for the construction of a model designed to explain the effects of quality management practices (QMP) on process innovation performance and the mediating role of dynamic capabilities in this relationship. The empirical data were analysed using the structural equation modelling technique by examining 6 competing models that represent full, partial mediation and non-mediation relationships on a sample of 550 Spanish industrial companies. The findings indicate that t…
A two-phase insertion technique of unexpected customers for a dynamic dial-a-ride problem
2006
Abstract This work deals with a dynamic dial-a-ride problem with time window constraints. In particular, new unplanned requests for service may arise at a vehicle stop and the driver must decide in real-time whether to accept or reject them. For this problem, we have developed a two-phase insertion algorithm based on route perturbations: the first phase, which is run off-line when the vehicle moves between two successive stops, aims at creating a feasible neighborhood of the current route; while the second phase, which is run in real-time every time a new request occurs, inserts, when possible, the delivery stop of the new customer in the current route.
Minimizing fleet operating costs for a container transportation company
2006
Abstract This paper focuses on a fleet management problem that arises in container trucking industry. From the container transportation company perspective, the present and future operating costs to minimize can be divided in three components: the routing costs, the resource (i.e., driver and truck) assignment costs and the container repositioning costs (i.e., the costs of restoring a given container fleet distribution over the serviced territory, as requested by the shippers that own the containers). This real-world problem has been modeled as an integer programming problem. The proposed solution approach is based on the decomposition of this problem in three simpler sub-problems associate…
Psychological contract profiles among permanent and temporary agency workers
2016
Purpose– Based on the psychological contract (PC) theory, the purpose of this paper is to identify PC profiles, differentiating between permanent and temporary agency workers (TAW). Moreover, the authors analyzed whether different profiles presented different levels of work engagement.Design/methodology/approach– A cross-sectional survey data analysis of 2,867 workers, of whom 1,046 were TAW, was analyzed using latent profile analyses.Findings– Four PC profiles were identified, which differed quantitatively in terms of the overall dimension levels (i.e. balanced, relational and transactional) for PC (i.e. content and fulfillment). ANCOVAs showed that the relational/balanced dominant and tra…
Wyodrębnione jednostki organizacyjne kościoła katolickiego. Stan de lege lata i postulaty de lege ferenda
2021
W artykule zostanie przeprowadzona analiza statusu prawnego wyodrębnionych kościelnych jednostek organizacyjnych, o których mowa w art. 12 Ustawy z dnia 17 maja 1989 r. o stosunku państwa do Kościoła katolickiego w Rzeczypospolitej Polskiej, uznanych przez właściwego miejscowo dyrektora izby administracji skarbowej za odrębne podmioty podatkowe. Zostanie wykazane, że ustalona w wymienionym przepisie reguła, iż jednostki te są wyłącznie organizacyjnym wyodrębnieniem w ramach kościelnych osób prawnych, z których osobowości prawnej korzystają w obrocie prawnym w stosunkach z podmiotami trzecimi, doznaje wyjątków na gruncie prawa pracy i prawa podatkowego. Ponadto zostaną wskazane mankamenty ob…
