Theorising about barriers to open e-learning systems in public administrations
2018
Abstract Barriers to the general use of e-learning technology are known across various contexts. Despite increasing efforts to clarify the range of these barriers, few efforts have been made to advance the theorising about them and, thus, to answer why and how they unfold. This study is motivated to overcome this unaddressed problem and develops a process model based on adaptive structuration theory (AST) and the punctuated socio-technical change model (PSIC). It represents how barriers unfold between actors, technology, and organisational properties in public administrations. The PaSIC model provides a new perspective on how critical incidents drive the emergence and progress of barriers t…
How can I signal my quality to emerge from the crowd? A study in the crowdsourcing context
2022
Crowdsourcing contests are characterized by an intensive level of competition because of the extensive number of solvers that voluntarily self-select to participate in such contests. This study aims at understanding how solvers can signal their quality attributes through the community functionalities, i.e. the online profile and the discussion blog of the crowdsourcing platform, to improve their chances of winning crowdsourcing contests. Drawing on signaling theory, we hypothesize that signaling their skills and capabilities by crafting profiles rich in personal and professional information and by participating actively within the discussion blog by posting and commenting, solvers can influ…
Filter multiplexing by use of spatial Code Division Multiple Access approach.
2003
The increasing popularity of optical communication has also brought a demand for a broader bandwidth. The trend, naturally, was to implement methods from traditional electronic communication. One of the most effective traditional methods is Code Division Multiple Access. In this research, we suggest the use of this approach for spatial coding applied to images. The approach is to multiplex several filters into one plane while keeping their mutual orthogonality. It is shown that if the filters are limited by their bandwidth, the output of all the filters can be sampled in the original image resolution and fully recovered through an all-optical setup. The theoretical analysis of such a setup …
Optical implementation of the weighted sliced orthogonal nonlinear generalized correlation for nonuniform illumination conditions.
2002
Optical pattern recognition under variations of illumination is an important issue. The sliced orthogonal nonlinear generalized (SONG) correlation has been proposed as an optical pattern recognition tool to discriminate with high efficiency between objects. But, at the same time, the SONG correlation is very sensitive to gray-scale image variations. In a previous work, we expanded the definition of the SONG correlation to the Weighted SONG (WSONG) correlation to modify the discrimination capability in a controlled way. Here, we propose to use the WSONG when pattern recognition is obtained by means of optical correlation under nonuniform illumination. The calculation of the WSONG correlation…
Single-channel polychromatic pattern recognition by the use of a joint-transform correlator.
2010
We present a single-channel system for color image recognition that is based on a joint-transform correlator setup. The color images are encoded as phase and amplitude functions, inspired from the Munsell color representation. A real-time implementation of the new codification method can be achieved by the use of a spatial light modulator operating in phase-only modulation mode. We determine the optimal codification for a linear color-phase code. Its performance is compared with a conventional multichannel correlator by means of computer simulations. Experimental results are also presented.
New sunphotometer for network operation.
1983
A handheld sunphotometer has been developed and is described. It operates for 9 wavelengths in the visible and near infrared. The sensitivity range is rather broad, so it can be used in turbid as well as clear atmospheres. The operation is simple, and a digital readout helps prevent operator biases. The instrument is sun powered and suitable for network operations. Determination of the atmospheric turbidity due to aerosol and the column content of O3, NO2, H2O is possible.
Involvement and image transfer in sports sponsorship
2017
Sponsorships have become one of the most important marketing tools. Data show that a majority of sporting events is sponsored and that investment in sponsorship is increasing every year. Companies are demanding more research to better unde rstand their investment efficacy. Involvement is a key element in processing sponsorship information in consumers’ minds. This variable affects consumer behavior and moderates the sponsor image transfer. The study of involvement could give guidance for the design of appropriate and functional advert ising campaigns. The research proposes segmenting and modelling sport consumer behaviour in sponsorship by their level of involvement with the event. For this…
The spanish banks in face of the corporate social responsibility Standards: previous analysis of the financial crisis
2013
Transparency of information in the field of CSR (Corporate Social Responsibility) is common to various standards. In recent years there has been a proliferation of standards and models for the formalization of CSR strategies. The objective is to assess the degree of implementation of standards of normalization. The analysis was conducted with data from the year 2008, coinciding with the first signs of the financial crisis, serving as a reference point to analyze the effect of the crisis. The field work was conducted using a survey answered by 57 Spanish credit institutions. We found a low degree of implementation of standards. The GRI (Global Reporting Initiative) and the ISO 14001 stood ou…

Brand image transfer from team to sponsor: how effective is it to sponsor a football team with little success
2019
We propose to explore the influence of success in sports on the effect of image transfer in sponsorship. We analysed three football teams based on their historical ranking. The image transfer does not occur with the less successful team. We conclude that sports sponsors need to reconsider their strategic options to align them with their company goals and to promote a return on investment. An ideal strategy to enhance the brand image would be to sponsor more successful sports teams because it has been shown that those teams that have more victories get greater exposure and therefore the ROI for sponsors increase.
