“Journal of Promotion Management"; Volume 21, Issue 4, 2015; copyright Taylor & Francis; available online at: http://dx.doi.org/10.1080/10496491.2015.1051407This research provides insight on the mechanisms through which knowledge acquired through promotional events and through spatial co-location simultaneously sustains firm s innovation. Applying
the concept of temporary clusters to promotional events, we simultaneously test how internal resources mediating effect and promotional events moderating role affect innovation in clusters.
Regression analyses with nonparametric bootstrapping and a large sample of Spanish clusters confirm the synergies derived from the combination of internal resources, local relationships, and complementary foreign events. Although extra-cluster linkages increase this effect, synergies creation requires attendance to international exhibitions or conventions. Valuable implications for practitioners
and policy makers are discussed.Belso Martínez, JA.; Mas Verdú, F.; Roig Tierno, H. (2015). Knowledge, Promotional Events, and the Contribution of Clustering to Innovation.

Hardware Project Development using Scrum in the Interactive Technologies Degree
[EN] Learning electronics in the fourth-wave industrial age requires an extra effort to motivate students. They often feel frustrated so they do not spend enough time to acquire in depth-knowledge. To enhance student's motivation and engagement, instructional methods of teaching and learning are being tested in some Universities [1]. Among these methods, project based learning (PBL) has proven to be useful to overcome frustration and improve student engagement. This methodology is even more successful if it is implemented using an agile approach, like Scrum. This paper describes a new way to teach electronics based on the use of PBL and Scrum and presents results of its application regarding to the acquisition level of some competences.This work has been partially finance by UPV-Innovation Project PIME-I 1776 (2022-2024).Pérez Pascual, MA.; Toledo Alarcón, JF.; Marín-Roig Ramón, J.; Azulay, E.

Pulmonary Vein Activity Organization to Determine Atrial Fibrillation Recurrence: Preliminary Data from a Pilot Study
[EN] Ablation of pulmonary veins has emerged as a key procedure for normal rhythm restoration in atrial fibrillation patients. However, up to half of ablated Atrial fibrillation (AF) patients suffer recurrences during the first year. In this article, simultaneous intra-atrial recordings registered at pulmonary veins previous to the ablation procedure were analyzed. Spatial cross-correlation and transfer entropy were computed in order to estimate spatial organization. Results showed that, in patients with arrhythmia recurrence, pulmonary vein electrical activity was less correlated than in patients that maintained sinus rhythm. Moreover, correlation function between dipoles showed higher delays in patients with AF recurrence. Results with transfer entropy were consistent with spatial cross-correlation measurements. These results show that arrhythmia drivers located at the pulmonary veins are associated with a higher organization of the electrical activations after the ablation of these sites.This research was funded by Spanish Ministry of Research and Innovation : PID2019-109547RB-I00.

Tool for assessing the adequacy of software to process ITIL incident management
[EN] The Information Technology (IT) and Information Systems (IS) are becoming increasingly
important in business and get help achieve their corporate objectives efficiently. This
importance is a growing trend, and based on that, the need to properly manage these IT
arises. To bring that management properly, a number of frameworks appear to perform such
management in a systematic and organized way. The implementation of these frameworks,
such as ITIL, is complex, and must be supported by the right tools. But it is not easy to know if
a tool is appropriate, or meets the requirements.
This paper presents a model for evaluating tools for managing one of the key processes
defined in ITIL is presented, as is the Incident Management process.[ES] Las Tecnologías de la Información (TI) y los Sistemas de Información (SI) son cada vez más
importantes en las empresas para conseguir alcanzar sus objetivos corporativos de forma

necesidad de gestionar de forma adecuada estas TI, y en relación con ello, una serie de
marcos de trabajo para llevar a cabo esa gestión de forma sistemática y organizada. La
implantación de estos marcos de trabajo, como es el caso de ITIL, resulta compleja, y debe
estar soportada por las herramientas adecuadas. Pero no es fácil saber si una herramienta es
adecuada, o se ajusta a las necesidades. En este trabajo se presenta un modelo de evaluación

From 12 to 1 ECG lead: multiple cardiac condition detection mixing a hybrid machine learning approach with a one-vs-rest classification strategy
[EN] Objective: Detecting different cardiac diseases using a single or reduced number of leads is still challenging. This work aims to provide and validate an automated method able to classify ECG recordings. Performance using complete 12-lead systems, reduced lead sets, and single-lead ECGs is evaluated and compared. Approach: Seven different databases with 12-lead ECGs were provided during the PhysioNet/Computing in Cardiology Challenge 2021, where 88,253 annotated samples associated with none, one, or several cardiac conditions among 26 different classes were released for training, whereas 42,896 hidden samples were used for testing. After signal preprocessing, 81 features per ECG-lead were extracted, mainly based on heart rate variability, QRST patterns and spectral domain. Next, a One-vs-Rest classification approach made of independent binary classifiers for each cardiac condition was trained. This strategy allowed each ECG to be classified as belonging to none, one or several classes. For each class, a classification model among two binary Supervised Classifiers and one Hybrid Unsupervised-Supervised classification system was selected. Finally, we performed a 3-fold cross-validation to assess the system's performance. Main results: Our classifiers received scores of 0.39, 0.38, 0.39, 0.38, and 0.37 for the 12, 6, 4, 3 and 2-lead versions of the hidden test set with the Challenge evaluation metric (CM). Also, we obtained a mean G-score of 0.80, 0.78, 0.79, 0.79, 0.77 and 0.74 for the 12, 6, 4, 3, 2 and 1-lead subsets with the public training set during our 3-fold cross-validation. Significance: We proposed and tested a machine learning approach focused on flexibility for identifying multiple cardiac conditions using one or more ECG leads. Our minimal-lead approach may be beneficial for novel portable or wearable ECG devices used as screening tools, as it can also detect multiple and concurrent cardiac conditions.This work was supported by PID2019-109547RB-I00 (National Research Program, Ministerio de Ciencia e Innovación, Spanish Government) and CIBERCV CB16/11/00486 (Instituto de Salud Carlos III).Jiménez-Serrano, S.; Rodrigo, M.; Calvo Saiz, CJ.; Millet Roig, J.; Castells, F.

de uno de los procesos clave definidos en ITIL, como es el proceso de Gestión de Problemas.[EN] In the competitive environment in which we are, proper management of Information
Technology (IT) and information systems (IS) is a strategic and fundamental aspect for
organizations to be able to achieve their corporate objectives. In that environment,
frameworks emerge to manage in the best way IT services in organizations. The
implementation of these frameworks, such ITIL, is complex, and must be supported by
appropriate tools. But it is not easy to tell if a tool is appropriate, or is adjusted to the needs.
This paper presents an evaluation model of tools to carry out the management of the
Problem Management process, one of the key processes defined in ITIL, as is the Problem
Management process.Roig-Ferriol, JM.; Oltra Badenes, RF. (2015). Propuesta de modelo de evaluación de herramientas para la gestión del proceso de gestión de problemas de ITIL. 3C TIC, cuadernos de desarrollo aplicados a las TIC. 4(1):26-42. http://hdl.handle.net/10251/94984S26424
Multiple Cardiac Disease Detection from Minimal-Lead ECG Combining Feedforward Neural Networks with a One-vs-Rest Approach
[EN] Although standard 12-lead ECG is the primary
technique in cardiac diagnostic, detecting different
cardiac diseases using single or reduced number of leads
is still challenging. The purpose of our team, itaca-UPV,
is to provide a method able to classify ECG records using
minimal lead information in the context of the 2021
PhysioNet/Computing in Cardiology Challenge, also using
only a single-lead.
We resampled and filtered the ECG signals, and
extracted 109 features mostly based on Hearth Rhythm
Variability (HRV). Then, we used selected features to train
one feed-forward neural network (FFNN) with one hidden
layer for each class using a One-vs-Rest approach, thus
allowing each ECG to be classified as belonging to none
or more than one class. Finally, we performed a 3-fold
cross validation to assess the model performance.
Our classifiers received scores of 0.34, 0.34, 0.27, 0.30,
and 0.34 (ranked 26th, 21th, 29th, 25th, and 22th out of 39
teams) for the 12, 6, 4, 3 and 2-lead versions of the hidden
test set with the Challenge evaluation metric.
Our minimal-lead approach may be beneficial for novel
portable or wearable ECG devices used as screening tools,
as it can also detect multiple and concurrent cardiac
conditions. Accuracy in detection can be improved adding
more disease-specific features.Jiménez-Serrano, S.; Rodrigo Bort, M.; Calvo Saiz, CJ.; Castells, F.; Millet Roig, J. (2021). Multiple Cardiac Disease Detection from Minimal-Lead ECG Combining Feedforward Neural Networks with a One-vs-Rest Approach. 1-4. https://doi.org/10.22489/CinC.2021.1091
Factors of regional poverty reduction in Colombia: Do institutional conditions matter?
[EN] Colombia has a unique history, which has been heavily conditioned by armed conflict lasting more than 50 years. This study examines the institutional conditions for success and failure in reducing poverty in Colombian departments by considering changes that took place between 2003 and 2014. Fuzzy-set qualitative comparative analysis identifies the changes in regional conditions that reduce poverty over time. The pathways for poverty reduction are multidimensional, and many involve changes in institutional attributes such as government transparency, absence of violence, and electoral turnout. The framework developed in this paper can be used to monitor necessary and sufficient pathways in regional clusters.This work was funded by Grant AGL2015-65897-C3-3-R, ¿Spanish Ministry of Science, Innovation, and Universities¿.Nieto-Alemán, PA.; García Alvarez-Coque, JM.; Roig Tierno, N.; Mas Verdú, F.

Multidimensional paths to regional poverty: a Fuzzy-set qualitative comparative analysis of Colombian departments
This is an Author's Accepted Manuscript of an article published in Nieto-Alemán, Paula Andrea, Roig Tierno, Honorat, Mas Verdú, Francisco, García Alvarez-Coque, José María. (2018). Multidimensional paths to regional poverty: a Fuzzy-set qualitative comparative analysis of Colombian departments.Journal of Human Development and Capabilities, 19, 4, 499-520. DOI: 10.1080/19452829.2018.1504760, available online at: http://doi.org/ 10.1080/19452829.2018.1504760[EN] This paper provides a simple, systemic, holistic assessment of regional conditions that lead to capability deprivation. Capability deprivation is measured at the regional level using the indicators of monetary poverty and life expectancy in Colombia. Fuzzy-set qualitative comparative analysis (fsQCA) is used to identify necessary or sufficient conditions for high and low deprivation in Colombian departments (regions). The multidimensional paths consist of combinations of economic conditions (GDP per capita and trade openness), social conditions (education) and institutional conditions (transparency and internal displacement). The observed interactions between conditions indicate that no single condition leads to regional poverty. Peace and transparent institutions are important conditions in most of the paths that lead to high or low capability or functioning indicators.This work was supported by the Ministerio de Economia y Competitividad [AGL2015-65897-C3-3-R].Nieto-Alemán, PA.; Roig Tierno, H.; Mas Verdú, F.; García Alvarez-Coque, JM.
