Transformational behaviors: Increasing work engagement in multinational environments
No full textThe role of a leader is fundamental to increase organizational culture and facilitate employee
engagement. However, organizations are not providing clear guidance on how to
do it. This study aims to determine the relationship between leadership styles and employee
engagement as well as to understand whether there is a correlation between an
engaged employee and extra effort. The study uses a Multi-Leadership Questionnaire
(MLQ-5x Rater Form) to measure employee perception of the leader styles and Utrecht
Work Engagement Scale (UWES-17) to determine employee engagement. The scope
of the study is limited to a sample of 167 employees from 7 different multinational
companies and 31 different nationalities.
Results show that all the transformational behaviors and, concretely the idealized behavior,
are significantly positively related to work engagement in multinational environments.
Results also reveal a strong correlation between employee engagement and extra effort.
The study concludes that leaders or managers should use transformational behaviors if
they want to increase engagement and extra effort with their teams. They should increase
transformational behaviors like being transparent, consistent, and having a strong sense
of purpose to catalyze a collective engagement. These results expand previous studies of
transformational leadership and work engagement in multinational environments
La formación lingüística en los Grados de Maestro: las nociones de ‘competencia comunicativa’, ‘razonamiento crítico’ y ‘género discursivo’
No full textEn este texto nos proponemos realizar un conjunto de reflexiones sobre la competencia comunicativa y el razonamiento crítico (a partir de ahora CCyRC) con respecto a la formación inicial de maestros y en el contexto de escritura académica. Se trata de dos aspectos considerados estratégicos en los Grados de Maestro y que han sido objeto ya de medidas concretas para su desarrollo en algunas universidades y comunidades autónomas en nuestro país en relación con el acceso a dicha formación. Aportamos una descripción conceptual de CCyRC y proponemos siete medidas clave sobre la base de que esas competencias deben ser trabajadas de manera transversal en todas las asignaturas implicadas en la formación inicial docente, a partir de la noción de “género discursivo”
A Model of the Threats that Disreputable Behavior Present to Esports Sponsors
No full textBoth esports sponsors and academia are not aware of how disreputable behavior in the esports scene can negatively affect their brands. Hence, this research aimed at identifying which types of disreputable behavior in competitive gaming present the biggest threats to esports sponsors. In this quantitative and exploratory research, a non-probability, purposive, and heterogeneous sampling method was employed to gather a sample of 1,592 esports fans who filled a closed-ended online survey. Results showed that illegal and unregulated gambling was a high-risk threat to esports sponsors; toxic behavior, match-fixing, and cheating were labeled as medium-risk threats; and sexism, cyberattacks, and doping were found to be low-risk threats. Besides being one of the first studies on esports sponsorships, which serves as a basis for future research in this market, the findings contribute to the sustainability of the esports industry and its sponsors. Managerial implications are also discussed
Using artificial intelligence as a diagnostic decision support tool to help the diagnosis of skin disease in primary healthcare in Catalonia
No full textPrograma de Doctorat: Medicina i Ciències BiomèdiquesLa tesi analitza el potencial de la intel·ligència artificial (IA) en el diagnòstic de lesions cutànies a l’atenció primària (AP) mitjançant tres estudis. El primer és una revisió sistemàtica que inclou 15 estudis publicats entre 2019-2022, centrats en la precisió diagnòstica de la IA. El segon estudi detalla el protocol per validar una eina d’IA per la lectura d’imatges dermatològiques, anomenada Autoderm®, en un entorn clínic real. El tercer estudi constitueix la validació externa del model amb 100 pacients, comparant els resultats amb els diagnòstics dels metges de família i dermatòlegs. Els resultats indiquen que la precisió diagnòstica global del model (Top-1 39%, Top-3 61%, Top-5 72%) és inferior a la dels professionals mèdics, tot i que millora quan es consideren els 44 diagnòstics entrenats (Top-1 48%, Top-3 75%, Top-5 89%). A més, el 92% dels professionals van valorar positivament l’ús de la IA pel suport en el diagnòstic diferencial.The thesis explores the potential of artificial intelligence (AI) in diagnosing skin diseases in primary care (PC) through three studies. The first is a systematic review of 15 studies published between 2019 and 2022, focusing on the diagnostic accuracy of AI. The second study outlines the protocol for validating an AI tool for analysing dermatological images, called Autoderm®, in a real clinical setting. The third study involves the external validation of the model with 100 patients, comparing its performance with diagnoses made by general practitioners and dermatologists. The results show that the model's overall diagnostic accuracy (Top-1 39%, Top-3 61%, Top-5 72%) is lower than that of medical professionals, although it improves when limited to the 44 diagnoses for which it was trained (Top-1 48%, Top-3 75%, Top-5 89%). Additionally, 92% of professionals positively evaluated the use of AI as a support tool for differential diagnosis
Mobile software testing and evaluation on real devices in higher education: An Irish Open Device Lab Case Study
No full textTesting and evaluation on real devices are a requisite for mobile development, but
this is still not mainstream practice. Software testing is not well accepted among
students, being perceived as a boring topic or useless, so, to teach software testing
in an effective way it's necessary to use real-life experimentation to show their
importance. This study is part of comprehensive research, which aims to explain
Open Device Labs (ODLs); a grass-roots community movement from the Web
development industry which later reached the game and academic sector. The
movement aims to democratize tests on real devices offering access to mobile
devices as a free service to local tech communities. Currently, there are 149 labs
located in 34 countries. Educational institutions have also established ODLs, but
there is little and superficial information about them. This study presents an intrinsic
qualitative case study about the IT Tralee ODL, one of the few labs hosted by a
higher education institution. We used an inductive approach for data analysis which
was based on online documents, interviews, direct observation, participant observation, and field notes. The findings contribute to understanding how an ODL
hosted by an educational institution works, as well as its main issues and benefits
A framework of how sponsoring esports benefits brand imatge
No full textThe purpose of this research was to identify the elements that facilitate or lead
brands to acquire an improved brand image as a result of sponsoring esports. A
conceptual framework was created and then improved by empirical data. This
exploratory and quantitative research analysed 1,611 esports fans who were
sampled through a non-probability purposive heterogeneous method. Empirical
data was gathered through an online and closed-ended survey. Data showed
that esports sponsorships provide seven main elements that benefit the
sponsors’ brand image. The field of esports sponsorships has been largely
ignored by academia. Hence, this research provides the first step in better
understanding the benefits of sponsoring esports and creates a foundation for
future studies to base themselves on. Knowing the main brand image-related
benefits of sponsoring esports will promote the confidence of brands that are
still reluctant about entering this new market
