An fMRI Study of Emotional engagement in decicion-making

It has been suggested that decisionmaking depends on sensitive feelings associatedwith cognitive processing rather than cognitiveprocessing alone. From human lesions, we knowthe medial anterior inferior-ventral prefrontalcortex processes the sensitivity associated withcognitive processing, it being essentiallyresponsible for decision making.In this fMRI (functional Magnetic ResonanceImage) study 15 subjects were analyzed usingmoral dilemmas as probes to investigate the neuralbasis for painful-emotional sensitivity associatedwith decision making. We found that a networkcomprising the posterior and anterior cingulateand the medial anterior prefrontal cortex wassignificantly and specifically activated by painfulmoral dilemmas, but not by non-painful dilemmas.These findings provide new evidence that thecingulate and medial anterior prefrontal areinvolved in processing painful emotionalsensibility, in particular, when decision makingtakes place. We speculate that decision makinghas a cognitive component processed by cognitivebrain areas and a sensitivity component processedby emotional brain areas. The structures activatedsuggest that decision making depends on painfulemotional feeling processing rather than cognitiveprocessing when painful feeling processinghappens

Emotional engagement and orienting: the effects of picture size on affective response

For their survival, humans and animals can rely on motivational systems which are specialized in assessing the valence and imminence of dangers and appetitive cues. The Orienting Response (OR) is a fundamental response pattern that an organism executes whenever a novel or significant stimulus is detected, and has been shown to be consistently modulated by the affective value of a stimulus. However, detecting threatening stimuli and appetitive affordances while they are far away compared to when they are within reach constitutes an obvious evolutionary advantage. Building on the linear relationship between stimulus distance and retinal size, the present research was aimed at investigating the extent to which emotional modulation of distinct processes (action preparation, attentional capture, and subjective emotional state) is affected when reducing the retinal size of a picture. Studies 1-3 examined the effects of picture size on emotional response. Subjective feeling of engagement, as well as sympathetic activation, were modulated by picture size, suggesting that action preparation and subjective experience reflect the combined effects of detecting an arousing stimulus and assessing its imminence. On the other hand, physiological responses which are thought to reflect the amount of attentional resources invested in stimulus processing did not vary with picture size. Studies 4-6 were conducted to substantiate and extend the results of studies 1-3. In particular, it was noted that a decrease in picture size is associated with a loss in the low spatial frequencies of a picture, which might confound the interpretation of the results of studies 1-3. Therefore, emotional and neutral images which were either low-pass filtered or reduced in size were presented, and affective responses were measured. Most effects which were observed when manipulating image size were replicated by blurring pictures. However, pictures depicting highly arousing unpleasant contents were associated with a more pronounced decrease in affective modulation when pictures were reduced in size compared to when they were blurred. The present results provide important information for the study of processes involved in picture perception and in the genesis and expression of an emotional response. In particular, the availability of high spatial frequencies might affect the degree of activation of an internal representation of an affectively charged scene, and might modulate subjective emotional state and preparation for action. Moreover, the manipulation of stimulus imminence revealed important effects of stimulus engagement on specific components of the emotional response, and the implications of the present data for some models of emotions have been discussed. In particular, within the framework of a staged model of emotional response, the tactic and strategic role of response preparation and attention allocation to stimuli varying in engaging power has been discussed, considering the adaptive advantages that each might represent in an evolutionary view. Finally, the identification of perceptual parameters that allow affective processing to be carried out has important methodological applications in future studies examining emotional response in basic research or clinical contexts.

Emotional engagement and brain potentials: repetition in affective picture processing

The present thesis addresses several experimental questions regarding the nature of the processes underlying the larger centro-parietal Late Positive Potential (LPP) measured during the viewing of emotional(both pleasant and unpleasant) compared to neutral pictures. During a passive viewing condition, this modulatory difference is significantly reduced with picture repetition, but it does not completely habituate even after a massive repetition of the same picture exemplar. In order to investigate the obligatory nature of the affective modulation of the LPP, in Study 1 we introduced a competing task during repetitive exposure of affective pictures. Picture repetition occurred in a passive viewing context or during a categorization task, in which pictures depicting any mean of transportation were presented as targets, and repeated pictures (affectively engaging images) served as distractor stimuli. Results indicated that the impact of repetition on the LPP affective modulation was very similar between the passive and the task contexts, indicating that the affective processing of visual stimuli reflects an obligatory process that occurs despite participants were engaged in a categorization task. In study 2 we assessed whether the decrease of the LPP affective modulation persists over time, by presenting in day 2 the same set of pictures that were massively repeated in day 1. Results indicated that the reduction of the emotional modulation of the LPP to repeated pictures persisted even after 1-day interval, suggesting a contribution of long-term memory processes on the affective habituation of the LPP. Taken together, the data provide new information regarding the processes underlying the affective modulation of the late positive potential.

Mobile Books: Effect of Engagement on Students’ Motivation and Cognitive Strategy Use

This mixed methods research explores the role of reading engagement in 30 grade 1 students’ motivation to read mobile electronic storybooks (eBooks) and cognitive strategies used during eBook reading. Data collection comprised motivation and parent questionnaires, behavioural observation checklists, cognitive strategies rubric, and teacher interviews. Students’ emotional engagement with and enjoyment of mobile eBooks corresponded to 4 motivational aspects of intrinsic motivation: curiosity, control, choice, and challenge. Post-intervention results indicated that most student participants enjoyed answering eBook comprehension questions and preferred eBooks to print books; by the end of the study, all had access to a mobile device at home. A majority of participants were actively engaged during mobile eBook reading sessions and persisted in answering embedded eBook comprehension questions, which together reflected students’ behavioural engagement and time-on-task during mobile reading. Students’ off-task behaviours related to iPads’ accessibility features and inherent reader-friendliness. All participants successfully answered evaluative questions requiring them to activate prior knowledge, and experienced higher levels of difficulty with making personal connections. The study highlights the importance of making school-based literacy practices relevant to students’ outside worlds, and discusses implications for teacher educators, administrators, curriculum developers, and eBook and other digital developers concerning the need for greater collaboration in order to more closely align technology resources with national curriculum expectations.

Engagement affectif, comportemental et cognitif des élèves du primaire dans un contexte pédagogique d’intégration des TIC : une étude multicas en milieux défavorisés

Réalisée en milieux défavorisés, cette étude porte sur l’engagement scolaire des élèves de troisième cycle du primaire (5e et 6e années au Québec) dans un contexte d’utilisation pédagogique des technologies de l’information et de la communication (TIC). L’objectif de cette recherche est d’analyser l’engagement d’élèves utilisant les TIC. Elle vise à décrire les pratiques pédagogiques d’intégration des TIC de dix enseignants, de relater la qualité de l’engagement de leurs 230 élèves lors de tâches TIC et de mesurer l’évolution et la qualité de leur engagement scolaire selon le degré de défavorisation de leur école. Pour ce faire, cette recherche s’est inspirée d’un cadre de référence traitant l’engagement scolaire selon les dimensions affective, comportementale et cognitive. De plus, cette étude multicas essentiellement de nature interprétative et descriptive a utilisé une méthodologie mixte de collecte et d’analyse des données. Les résultats montrent notamment que les enseignants accordent une valeur pédagogique importante aux TIC tant dans la fréquence de leur utilisation, dans les usages valorisés que dans la façon de les intégrer en classe. Les enseignants privilégient largement le traitement de texte et la recherche sur Internet, mais très peu d’autres usages pertinents sont mis de l’avant de manière soutenue. La majorité des enseignants interrogés préférerait se servir de quatre ordinateurs en classe pour utiliser les TIC plus facilement que d’avoir uniquement accès au laboratoire de leur école. De plus, ils perçoivent de manière unanime que l’utilisation des TIC exerce une influence importante sur la dimension affective de leurs élèves lors d’activités préparées, assez bonne sur la dimension comportementale et plus discutable sur la dimension cognitive. Plus globalement, les élèves eux-mêmes affichent en général un engagement scolaire relativement élevé. En six mois, la qualité de l’engagement affectif des élèves est restée stable, leur engagement comportemental a progressé, mais leur engagement cognitif a baissé légèrement. Les résultats montrent aussi que la qualité de l’engagement des élèves de milieux défavorisés évolue différemment selon le degré de défavorisation de leur école. Dans cette recherche, l’importance de l’utilisation des TIC sur la qualité de l’engagement est marquante et s’avère parfois meilleure que dans d’autres types de tâches. Sans pouvoir généraliser, cette étude permet aussi de saisir davantage la qualité et l’évolution de l’engagement scolaire des élèves de la fin du primaire en milieux défavorisés. Des recommandations pour le milieu et des pistes de recherches futures sont présentées en tenant compte des limites et des forces de cette thèse inédite réalisée par articles.

Comportements oppositionnels et engagement scolaire : effet modérateur de la relation maître-élève.

Les élèves aux problèmes de comportements externalisés comme l'opposition éprouvent généralement de la difficulté à s’engager dans leurs apprentissages (Janosz, 2000). Or, un faible engagement scolaire peut générer des problèmes d’ordre académique et mener au décrochage. Toutefois, certains facteurs environnementaux tels que la relation maître-élève semblent influer sur l’investissement des élèves dans les activités scolaires. La présente étude vise à examiner le lien entre le degré d'opposition d'élèves du 2e cycle du primaire et leur engagement comportemental et affectif en français. Elle tente aussi de vérifier si la chaleur ou les conflits présents dans la relation maître-élève agissent comme facteurs de protection ou comme facteurs aggravants face à l’engagement scolaire des élèves oppositionnels. Finalement, cette étude s’intéresse à l’effet différentiel de la relation maître-élève sur l’engagement scolaire des garçons et des filles. Des régressions linéaires multiples hiérarchiques effectuées sur 385 élèves québécois ont permis d’atteindre ces objectifs. Les résultats obtenus révèlent que la chaleur n’agit pas à titre de facteur de protection en ce qui a trait à l’engagement comportemental des élèves oppositionnels, mais qu’elle est bénéfique pour l’engagement comportemental des filles. Les résultats confirment également l’effet aggravant des conflits sur l’engagement comportemental des élèves oppositionnels. Finalement, cette étude indique que les conflits élèves-enseignants sont nuisibles pour l’engagement affectif des garçons. Les implications de ces résultats pour la recherche et pour l’intervention en psychoéducation seront présentées.

L'engagement scolaire des enfants hyperactifs et inattentifs : effets modérateurs des relations sociales

Les élèves qui ont un bon engagement scolaire présentent généralement une bonne adaptation à l’école. Cependant, pour les enfants hyperactifs et inattentifs, cette adaptation est souvent altérée. Les enfants qui entretiennent de bonnes relations sociales ont tendance à présenter un meilleur engagement comportemental, affectif et cognitif. La présente étude vise à déterminer si la prosocialité envers les pairs et les relations chaleureuses avec les enseignants protègent les enfants hyperactifs-inattentifs d’un possible désengagement scolaire. Les données ont été recueillies auprès de 513 élèves du primaire et leurs enseignants au cours de deux années scolaires successives. Les résultats montrent que ces enfants bénéficient des relations positives avec les pairs et les enseignants. En particulier, l’engagement comportemental de ces élèves demeure plus élevé comparativement à ceux qui n’entretiennent pas de relations positives. Pour les enfants très hyperactifs-inattentifs, la relation chaleureuse modère le lien entre hyperactivité-inattention et engagement affectif. L’hyperactivité- inattention ne prédit pas de diminution d’engagement affectif et cognitif. Les implications pour la recherche et la pratique sont discutées.

University students' engagement: Development of the university student engagement inventory (USEI)

Student engagement is a key factor in academic achievement and degree completion, though there is much debate about the operationalization and dimensionality of this construct. The goal of this paper is to describe the development of an psycho-educational oriented measure – the University Student Engagement Inventory (USEI). This measure draws on the conceptualization of engagement as a multidimensional construct, including cognitive, behavioural and emotional engagement. Participants were 609 Portuguese University students (67 % female) majoring in Social Sciences, Biological Sciences or Engineering and Exact Sciences. The content, construct and predictive validity, and reliability of the USEI were tested. The validated USEI was composed of 15 items, and supported the tri-factorial structure of student engagement. We documented evidence of adequate reliability, factorial, convergent and discriminant validities. USEI’s concurrent validity, with the Utrecht Work Engagement Scale-Student Survey, and the predictive validity for self-reported academic achievement and intention to dropout from school were also observed.

School engagement and burnout in a sample of brazilian students

Objective: Some studies have suggested that school engagement can be an ally in the prevention of psychosocial and occupational risks, to which students are exposed daily. The aim of this study is to estimate the impact of emotional, behavioral, and cognitive engagement on burnout syndrome among pharmacy undergraduate students. Methods: A total of 363 students enrolled in the pharmacy undergraduate program in the College of Pharmaceutical Sciences at Sao Paulo State University’s Araraquara Campus (UNESP) participated, 78.0% of whom were female. Mean age was 20.3 (SD = 2.7) years. The Maslach Burnout Inventory for students (MBI-SS) and the University Students School Engagement Inventory (USEI) were used. Confirmatory factor analysis was performed to assess the psychometric properties of the instruments. The data were included in a structural equation model in which burnout was considered the central construct. The impact of school engagement on burnout was based on the statistical significance of causal paths (β) evaluated by z tests (α = 5%). Results: The psychometric properties of the MBI-SS and USEI were adequate and the structural model also presented an adequate fit. Behavioral engagement (β = −0.56) and the emotional engagement (β = −0.71) explained 81.0% of burnout variability in the sample. Cognitive engagement was not found to contribute significantly. This data provides evidence of the impact of school engagement on burnout that can be used by educators and policymakers in charge of educational process. Conclusion: School engagement presented inverse and significant influence on burnout syndrome among pharmacy students.

Design thinking framework of experience innovation

Innovation remains one of the key drivers of sustainable and successful business. The variety of innovation approaches such as open models, intersectional thinking and co-creation tackles the challenge of viable novel offerings across the world. These approaches have certain similarities and their elements constitute design thinking. Recent market and society trends such as technological advances and globalization have intensify companies’ interaction with customers. Emotional engagement, pleasing communication and delight have gained equal to functionality importance. The complex of these components constitutes consumer experience. Academic research conceptualizes these changes by introducing customer-centered innovation, which replaces product-oriented approaches. However, both methods omit experience concept and provide fragmented explanation of experience innovation. Experience is an essential process of offering perception, which drives customer decisions. Therefore, an agenda of experience innovation development can systemize and explain the mechanisms of experience innovation. The purpose of this study is to create and explain the stage process framework of experience innovation by the means of design thinking approach. The research proceeds in accordance with the following sub-objectives: 1. Conceptualization of consumer experience through customer value. 2. Creation of experience innovation framework by the means of design thinking. This study is conducted by the means of conceptual research methods. The main theoretical contribution of the study is creation of the integrated framework of consumer experience innovation. The elaboration of design thinking agenda and methods applied to experience design builds the guidelines of experience innovation development. This research synthesizes the conceptual elements of the framework that resolves inconsistencies and duplications of theories. This essential clarification simplifies application of the experience innovation agenda, which can be useful for the wide range of specialists, from marketing to strategists, and from managers to entrepreneurs, willing to offer compelling experience to customers. The study highlights the crucial role of consumer experience in maintaining customer loyalty and designs the roadmap of innovating experience through the communication with customers.

Emociones y toma de decisiones éticas: desarrollo e implicaciones para la empresa

Los líderes organizacionales se deben enfrentar a retos ambientales del mundo de los negocios y diversas presiones que los ponen día a día en un alto riesgo ético. Sortear dichos riesgos ha demandado cambios sustanciales en las dinámicas de las organizaciones contemporáneas, por lo que las exigencias a los directivos de tomar decisiones acertadas en situaciones de alta complejidad moral son cada vez mayores. Estas decisiones involucran un comportamiento ético de quien las toma, lo cual a su vez está mediado por sus emociones.

The experience of immediacy: emotion and enlistment in fact-based theatre

This article discusses emotion as a strategy of political agency in post-Thatcherite documentary theatre. The 1990s saw a renaissance in theatre writing based in directness and immediacy but based in two quite different forms of drama, In-Yer-Face theatre and fact-based drama. There are clear distinctions between these forms: the new brutalist writing was aggressively provocative; documentary theatre engaged the audience by revealing an urgent truth. Both claimed a kind of realism that confronted actuality, be that of situation or experience, through forms of theatre that cultivated emotional engagement. In-Yer-Face theatre used emotional shock to penetrate the numb cynicism that its creators perceived. Documentary theatre used observation and the cultivation of sympathy to enlist its audience in a shared understanding of what was hidden, not understood or not noticed. The article analyses the functioning of emotional enlistment to engage the audience politically in two examples of documentary theatre, Black Watch and Guantanamo

Herramientas de gestión de compromiso para trabajadores del conocimiento

El objetivo de la línea de investigación seguida en esta tesis consiste en identificar palancas de gestión de las personas en las organizaciones que permitan mejorar su rendimiento mediante la gestión del compromiso de los profesionales de las organizaciones inmersas en la denominada sociedad del conocimiento. Para identificar dichas palancas se analizan algunos de los factores que, según la literatura científica, tienen como consecuencia cambios en la productividad, como son el compromiso organizacional y las conductas cívicas dentro de la organización. También, por su actualidad y relevancia en las prácticas de gestión de recursos humanos, se han analizado el impacto que tienen en estos factores en las prácticas empresariales que permiten conciliar vida profesional y personal el efecto del género en las distintas variables analizadas. Por todo lo anterior, en la investigación se analizan algunos de los factores de carácter psicosocial que promueven el compromiso en una organización, y se profundiza en dos conceptos: el análisis del compromiso de los profesionales con la organización para la que trabajan, y los comportamientos de ciudadanía organizativa que se exhiben en la organización por sus miembros. Para ello, se realiza un encuadramiento teórico de los siguientes conceptos: el compromiso como eje del trabajo; la ciudadanía organizativa como modelo cultural de la organización que promueve el compromiso; el rol de los líderes; los efectos de las políticas de conciliación; las diferencias de percepciones derivadas del género y un sistema de revisión de retributiva eficiente y coherente con el marco conceptual planteado. La metodología seleccionada para este trabajo ha sido el análisis en profundidad del caso de una empresa española, Red Eléctrica de España a través de tres pilares básicos: el primero consiste en el análisis exhaustivo de los datos obtenidos en las dos encuestas de clima social que dicha empresa realizó en el período 2006-2009; el segundo se centra en el desarrollo de un modelo matemático para el cálculo eficiente de recompensas salariales a través de un modelo de optimización; y el tercero es la consecuencia del conocimiento profundo que el autor tiene de la propia empresa, su cultura y funcionamiento, fruto de su experiencia profesional como directivo en el área de desarrollo de recursos humanos, función que desempeñó en la organización durante nueve años. En el análisis de este caso se ha investigado la influencia del género en el compromiso y la ciudadanía organizativa de los empleados de dicha organización, para identificar las diferencias de percepción que puedan ser explicadas por el género en una empresa muy masculina como es aquella. También, se ha incluido en este estudio de caso el análisis del efecto que presentan las medidas de conciliación en el compromiso de los empleados, por la relevancia que tiene este asunto en el panorama laboral español actual. Este análisis permite conocer hasta qué punto son o no motivadoras estas medidas en la organización analizada y, como consecuencia de ello, el tipo de gestión más oportuna de las mismas para conseguir no sólo los fines sociales que pretenden, garantizar que los empleados puedan compatibilizar sus exigencias laborales con una vida personal adecuada, sino también mejorar el clima, productividad y compromiso de éstos con la empresa. Para completar este análisis del caso, se han identificado de forma analítica los factores que mejor explican el clima de la organización y se ha concluido el papel central de la dirección que se concreta en la actuación de cada jefe, como motor del clima social en el equipo que dirige. Dado que la tesis pivota sobre el papel relevante que tiene la generación de una cultura de ciudadanía organizativa, se ha complementado el análisis con el desarrollo una herramienta de cálculo que facilita la determinación de los incrementos de la retribución fija de acuerdo con los principios de transparencia, equidad y justicia acordes con el modelo de empresa que promueve la virtud cívica de las personas empleadas en ella. Para ello se ha desarrollado un nuevo método de cálculo del incremento de retribución fija mediante un modelo analítico innovador y compacto de programación lineal entera mixta. Este modelo permite a las organizaciones realizar diseños de política retributiva de forma sencilla y rápida, a la vez que facilita la transparencia de las mismas en el proceso de gestión de la compensación. No se ha abordado el asunto de la determinación de la retribución variable, por ser un asunto relativamente menos complejo y profusamente tratado en la práctica directiva de las empresas. La primera de las conclusiones de la investigación realizada se refiere a los aspectos de la cultura organizativa que pueden identificarse como motores del compromiso. Se concluye que en el caso de estudio hay una fuerte relación mutua entre los rasgos que definen el compromiso emocional y los rasgos que determinan un comportamiento caracterizado como de ciudadanía organizativa. Se ha encontrado una correlación significativa y alta entre indicadores de compromiso y factores que recogen comportamientos de ciudadanía organizativa, correlación muy notable tanto para los factores de compromiso racional como para los de compromiso emocional. También se ha evidenciado que la correlación entre compromiso emocional y rasgos de comportamientos de ciudadanía organizacional es mayor que la que aparece entre compromiso racional y rasgos de comportamientos de ciudadanía organizacional. Desde el punto de vista de la práctica de gestión de recursos humanos, estas relaciones indican la conveniencia de promover una cultura organizacional basada en los principios de la ciudadanía organizativa para alcanzar altos niveles de compromiso emocional de los profesionales y mejorar la eficiencia organizativa. La segunda de las conclusiones se refiere al efecto de las políticas de conciliación en las organizaciones. Sobre este asunto se concluye que en el caso de estudio no puede considerarse que las medidas de conciliación tengan una fuerte relación con el compromiso emocional, y menos que puedan considerarse directamente una herramienta de generación de compromiso emocional. Sin embargo, sí que se detecta una cierta relación entre las percepciones de conciliación y de compromiso con la organización, y sobre todo, con el compromiso racional con la organización, que puede tener que ver con que para los empleados de la organización analizada, las medidas de conciliación son consideradas como una parte más de las condiciones laborales que ofrece la organización a los trabajadores. La tercera conclusión se refiere a la relación entre el género de los trabajadores y su nivel de compromiso y de ciudadanía organizativa. En el caso de estudio no se identifica una relación entre el género y el nivel de compromiso de los profesionales ni tampoco con la percepción de ciudadanía organizativa, variando la situación del período 2006 al período 2009. La cuarta conclusión se refiere al impacto que la actuación de los líderes (jefes) tiene en el clima social. En el caso de estudio, la actuación de los directivos y el nivel de compromiso que genera en los profesionales explica por sí sola más de un tercio de la varianza del clima organizativo, entendido como tal el que refleja el conjunto global de preguntas que constituyen la encuesta de clima del caso de estudio. Del análisis realizado se concluye que en el caso de estudio la percepción que los empleados tienen de sus jefes tiene un efecto relevante sobre el resto de percepciones de compromiso, ciudadanía organizativa y otros factores que conforman el clima social de la organización. La quinta y última conclusión supone la aportación de un modelo novedoso de cálculo de la recompensa económica coherente con un modelo de gestión empresarial mediante una cultura de ciudadanía organizativa. La solución que obtiene este modelo es el incremento salarial individual de cada profesional, que tiene en cuenta su rendimiento, posicionamiento salarial y encuadramiento profesional. Además de las restricciones presupuestarias, se consideran los principios de transparencia, equidad y justicia coherentes con el modelo conceptual planteado. La principal contribución de este trabajo es la formulación matemática de los criterios cualitativos que se emplean habitualmente en el proceso de revisión salarial. El método planteado supone una innovación que permite automatizar la metodología tradicional de gestión de incrementos salariales basados en matrices de incremento, así como evitar la aplicación de limitaciones en las valoraciones de desempeño derivadas de las restricciones presupuestarias que toda organización tiene. De esta manera se puede disponer de un mecanismo de revisión salarial que tiene en cuenta el desempeño de los profesionales, pero que permite la gestión “desacoplada” de la evaluación de rendimiento y la actualización de la retribución fija. ABSTRACT The aim of the research pursued in this thesis is to identify some human resources management levers in organizations to improve their performance through individual’s commitment management, focusing in organizations immersed in the so-called knowledge society. In order to find out these levers, the author analysed some of the psychosocial factors that promote engagement to the organizations and, according to the scientific literature, have effects in their productivity. These factors analysed are organisational commitment and citizenship behaviours. Additionally, the investigation also focuses on work-life balance policies and gender considerations, because of their relevance and topicality for the human resources’ policies. In the light of this, the investigation focuses on some of the psychosocial factors that promote organisational commitment, and delves into two concepts: the analysis of the commitment of professionals to the organization for which they work, and the organizational citizenship behaviours exhibited in the organization by its members. For this, a theoretical framework is performed for the following items: the professional’s commitment which is the pillar of this work; the organisational citizenship as a cultural model to promote that commitment; the role of the leaders; the effects of the work-life balance policies; the different perceptions of the professionals because of their gender; and an efficient salary review system, which is coherent with the conceptual framework set. The methodology selected for this work was the analysis in depth of the case of a Spanish company, Red Eléctrica de España, through three basic subjects: the first consists of a thorough analysis of the data obtained in the two work climate surveys made by this company in 2006 and 2009; the second focuses on the development of a mathematical model for calculating efficient salary reviews through an optimization model; and the third is the result of the author’s deep understanding of the company, its culture and its performance because of his professional experience as a manager in the area of human resource development, which was his role in the organization for nine years. The author investigated in the analysis of this case about the influence of gender on the employees’ organizational commitment and citizenship behaviours, in order to find out perception differences that can be explained by the highly masculine organisational culture such Red Eléctrica de España had during the studied period. Additionally, because of the importance of the work-life balance promotion in the Spanish labour scene, the case study analysis includes their effect in the employees’ commitment. This analysis allows to know motivating are these measures in the studied organization and, as a result, the most appropriate type of management thereof for social purposes, not only intended to ensure that employees can balance their work and personal demands, but also improving the work climate, the productivity and the organisational commitment. The investigation identifies the factors which best explain the work climate of the organization and concludes the central role of the leadership, embodied in the performance of every manager, to boost the work climate in their teams. Since this thesis pivots on the important role the generation of a culture of organizational citizenship has, the investigation has been complemented with the development of a analytic tool that facilitates the calculation of the salary review increments according to the principles of transparency, equity and justice in line with a work culture that promotes organisational citizenship behaviours. For this, this works develops a new method for calculating fixed salary increases through an innovative and compact mixed integer linear programming model. This model enables organizations to design compensation policies easily and quickly, and facilitates the transparency of the compensation management system. The method for determining variable remuneration has not been addressed because it is relatively less complex issue and widely discussed. The first conclusion of the conducted investigation concerns aspects of organizational culture that could be identified as commitment drivers. In the case study exists a strong and mutual relationship between the characteristics defining the emotional commitment and the organisational citizenship behaviours. The investigation has found out a meaningful and high correlation between indicators of commitment and the factors collecting organizational citizenship behaviour. This correlation with organisational citizenship is remarkable for both, rational and emotional, commitment. The correlation between organizational citizenship behaviours and emotional commitment and is greater than the one with rational commitment. From the practitioner point of view, these relationships show the importance of promoting an organizational culture based on the principles of organizational citizenship to achieve high levels of emotional engagement of professionals and improve organizational efficiency. The second conclusion relates to the effect of work-life balance policies in organizations. On this matter, the investigation concludes that for the case study, work-life balance measures do not have a strong relationship with the emotional commitment, and unless they can be usually considered as a tool to improve employees’ emotional commitment. However, a certain relationship between perceptions of work-life facilities and organisational commitment exists, especially with the rational commitment to the organization. This relationship appears because for employees of the analysed organization, work-life balance measures could be considered as a part of working conditions offered to them by the organization. The third conclusion concerns the relationship between the gender of workers and their level of commitment and organizational citizenship. In this case study, there is not any relationship between gender and the professional’s commitment level nor the perception of organizational citizenship; and the situation varies during the period studied. The fourth conclusion refers to the impact that the actions of the leaders have on the work climate. In the case study, the performance of management and the level of commitment generated, explains more than a third of the variance of work climate - understood as such reflecting the overall set of questions that constitute the work climate survey -. The analysis concludes that in the case study perception that employees have of their leaders has a significant effect on the rest of perceptions of commitment, organizational citizenship and other factors making the work climate of the organization. The fifth and last conclusion represents the contribution of a new model for calculating the salary increment, coherent with a corporate citizenship management culture. The solution obtained from this model consists of salary increases for each employee; these increases consider the employee’s professional performance, salary level relative to peers within the organization, and professional group. In addition to budget constraints, we modelled other elements typical of compensation systems, such as equity and justice. The major contribution of this work is the mathematical formulation of the criteria that are typically the basis for salary management. The compact formulation and the ease of obtaining the optimal solution facilitate its use in large companies that maintain very high levels of homogeneity across employees. Designing different strategies for specific groups within a company is also possible. A major benefit of this method is that it allows a company to independently manage its salary and assessment policies. Because obtaining salary-revision matrices without using the mathematical model we present in this paper is typically done iteratively by tuning previously defined matrices, managers commonly tune values for assessing employee performance to ensure that salary increases and performance assessments are consistent; however, this distorts the evaluation process and decreases employee motivation. In this MILP model, employee performance is only one parameter of several input parameters used in designing a salary policy that is independent of the results of performance-assessment values.
