La présente recherche a comme objectif d’étudier l’effet de l’environnement de travail sur l’engagement affectif envers son organisation. Le concept de l’environnement de travail se compose de trois dimensions, à savoir les caractéristiques de l’emploi, la communication managériale et la perception du soutien organisationnel. Cette recherche vise également à comprendre s’il existe un effet modérateur de la génération sur la relation entre ces dimensions de l’environnement de travail et l’engagement affectif. Les générations Baby-boomers, X et Y sont celles à l’étude. Les données ont été collectées au sein de deux compagnies privées dont la main-d’œuvre n’est pas syndiquée. Au total, 110 participants ont répondu au questionnaire. Des analyses de régression multiple ont permis de vérifier l’effet distinct de chaque dimension de l’environnement de travail sur l’engagement affectif alors que des analyses de régression hiérarchique ont testé la présence d’un effet modérateur de la génération dans cette relation. Les résultats indiquent que les seules dimensions de l’environnement de travail ayant un effet direct et significatif sur l’engagement organisationnel affectif sont la communication managériale et la perception du soutien organisationnel. En ce qui a trait à la génération à laquelle appartient le travailleur, il semble que cette variable ne modère pas la relation entre les dimensions de l’environnement de travail et l’engagement affectif. Les apports théoriques et pratiques de cette étude sont discutés tout comme ses limites et quelques recommandations pour les recherches futures. / The objective of the present research is to study the effect that the work environment can have on affective commitment toward the organization. The concept of work environment is divided into three dimensions. They are the job characteristics, the communication with the supervisor and the perceived organizational support. This research also wishes to understand if there exists a moderating effect of the generation on the relationship between these dimensions of the job environment and affective commitment. The generations of the Baby-boomers, X and Y are the one selected for the purposes of this study. The data were collected in two private and non-unionized companies. In total, 110 participants answered the questionnaire. Regression analysis were conducted to verify the distinct effect of each of the three dimensions of the work environment on the affective commitment and also to test the presence of a moderating effect of the generation in this relationship. The results indicate that the only dimensions of the work environment having a direct and significant effect on the affective organizational commitment are communication with the supervisor and perceived organizational support. Concerning the generation of the worker, it seems that this variable does not moderate the relationship between the dimensions of work environment and affective commitment. The theoretical and practical implications of this research are discussed as well as its limits and recommendations for future researches.

Ce mémoire a pour but d’étudier les facteurs professionnels et leur relation avec la détresse psychologique. L’objectif principal est d’évaluer l’effet modérateur du facteur professionnel de la latitude décisionnelle sur la relation entre la détresse psychologique et les facteurs professionnels étudiés. Pour ce faire, nous avons étudié la latitude décisionnelle de façon décomposée (utilisation des compétences et autorité décisionnelle). Les données sur lesquelles nous nous sommes basés proviennent de l’Équipe de Recherche sur le Travail et la Santé Mentale (ERTSM) et ont été recueillies au cours des mois de décembre 2008 et janvier 2009. L’échantillon utilisé se compose de 410 travailleurs, dont l’âge varie de 20 à 58 ans. Les analyses multivariées que nous avons réalisées nous ont permis d’identifier deux facteurs professionnels qui s’associent de manière significative à la détresse psychologique, soit les demandes psychologiques et la relation avec le supérieur immédiat. Les résultats de la régression logistique nous ont permis de déterminer que les travailleurs qui ont une bonne relation avec leur supérieur immédiat ont une probabilité inférieure (0.91) de développer de la détresse psychologique. Tandis que les travailleurs qui ont de fortes demandes psychologiques ont une probabilité 1.11 fois plus grande de développer de la détresse psychologique. Contrairement à l’hypothèse soutenue, le fait d’occuper l’emploi de policier par rapport au travail de bureau n’augmente pas la prévalence de détresse psychologique. De plus, les variables modératrices ne sont pas associées de façon significative avec la détresse psychologique. / This thesis aims to study some occupational factors and their relationship with psychological distress. The main objective of this master's thesis is to determine the moderator effect of decision latitude (decision authority and skill level) on the relationship between psychological distress and occupational factors. We use data from the Team for Research on Work and Mental Health (ERTSM). This research team collected the data during the month of December 2008 and January 2009. The sample consists of 410 workers whose ages range from 20 to 58 years. The multivariate analyses that we conducted allowed us to identify two occupational factors which are significantly associated to psychological distress. Those are psychological demands and the relationship with the supervisor. The results of logistic regression analyses show that workers who have a good relationship with their immediate superior have a lower probability (0.91) of developing psychological distress. On the other hand workers with high psychological demands have an odds ratio 1.11 times greater than those with low demands of developing psychological distress. Contrary to the hypothesis put forward, police officers do not have a higher probability of developing psychological distress than clerical workers. Furthermore, moderating variables are not significantly associated with psychological distress.

Organisations worldwide are experiencing an explosion of knowledge in the current technological information age as well as a serious skills shortage. The fast-paced aggressive and highly cyclical nature of the profession which often does not provide employees with the necessary resources and support causes employees in the information technology (IT) industry to show high turnover intent which is extremely costly and detrimental to organisational success. IT specialists are becoming a scarce commodity in a highly competitive environment where financial gain is very important and employee well-being is not necessarily a prerogative. Employers are faced with additional obligations than just paying equitable salaries, such as creating an environment that is conducive towards well-being. Efforts to promote flourishing and optimal functioning of employees will affect individual and organisational outcomes. Flourishing and languishing are opposite end points on a continuum of mental health indicating the emotional, psychological and social well-being of individuals. An individual who feels well (emotional well-being) is more likely to function well (psychological and social well-being) which means meeting the criteria for positive mental health as flourishing. Investments in the well-being of employees lay the basis for positive employment relations. The aim of this study was to investigate the flourishing of employees in the information technology industry and to determine the antecedents and outcomes thereof. A cross-sectional survey design was used to gather data regarding the flourishing of IT professionals and its outcomes. A convenience sample (N = 205) was taken of employees in information technology organisations in South Africa. The measuring instruments used were the Mental Health Continuum Short Form, Job Satisfaction Scale, Work Engagement Scale, Work-related Basic Need Satisfaction Scale, Work Role Fit Scale, Psychological Contract Inventory, Violations of PC Questionnaire, Organisational Commitment Scale, Turnover Intention Scale and Counterproductive Work Behaviour measures. The results of study 1 showed that 58.5% of the IT professionals were neither languishing nor flourishing, while 3.9% were languishing. Flourishing strongly impacted job satisfaction and had minor to moderate direct and indirect effects on organisational citizenship behaviour and organisational commitment. Job satisfaction impacted directly and positively on organisational commitment and negatively on turnover intention; and moderately negatively on counterproductive behaviour. Flourishing had both a direct and positive effect, and an indirect and negative effect (via organisational commitment) on turnover intention. Study 2 showed that psychological contract breach and violation strongly and negatively impacted flourishing at work and in life. The results provided support for a model in which psychological contract breach and violation had both direct and indirect effects via satisfaction of psychological needs on job satisfaction, work engagement, turnover intention and flourishing of IT professionals. Study 3 showed that work role fit and the availability of resources were strong predictors of flourishing at work and in life. Work role fit, the availability of resources, and supervisor relations impacted job satisfaction and social well-being indirectly through autonomy satisfaction. The availability of resources impacted work engagement and psychological well-being indirectly via competence satisfaction. Furthermore, work role fit, the availability of resources, and supervisor relations impacted psychological well-being indirectly through relatedness. Recommendations for future research were made. / PhD, Labour relations management, North-West University, Vaal Triangle Campus, 2012

Social workers worldwide play a pivotal role in delivering social services to those in need of such services. Designated social workers (DSWs) deliver statutory services pertaining to the protection of children in need of care and protection. All social workers are confronted by several professional risk factors that jeopardise their well-being; yet risks specifically observed in DSWs support the plea to enhance their resilience. The purpose of this qualitative phenomenological inquiry was to explore pathways of resilience among resilient South African DSWs by studying relevant literature and examining South African DSWs’ lived experiences. A secondary purpose was to draw on these experiences and literature to develop guidelines for South African DSW supervisors who may encourage the promotion of DSW resilience. Conducting a qualitative research synthesis was the first step and resulted in the confirmation of social worker risk and a deficient understanding of South African DSW resilience. An advisory panel of social work, DSW, and resilience experts assembled and formulated indicators of resilience in resilient South African DSWs, namely: a value-embedded life, having a support network, and having personal strengths, which, next, facilitated the identification of 15 resilient South African DSWs through snowball sampling. These 15 DSWs wrote narratives and were interviewed through semi-structured interviews in order to explore their lived experiences of workplace risks and their resilience processes. The findings concluded that these DSWs adapted to workplace adversities by living a purpose- and practice-informing creed, enjoying supportive collaborations, engaging in constructive transactions, and accentuating the positive. Guidelines for South African DSW supervisors, which emerged from these findings and literature, were proposed to be framed by reflective supervision as a step towards promoting South African DSW resilience. / PhD (Social Work), North-West University, Vaal Triangle Campus, 2014

La present tesi pretén recollir l'experiència viscuda en desenvolupar un sistema supervisor intel·ligent per a la millora de la gestió de plantes depuradores d'aigües residuals., implementar-lo en planta real (EDAR Granollers) i avaluar-ne el funcionament dia a dia amb situacions típiques de la planta. Aquest sistema supervisor combina i integra eines de control clàssic de les plantes depuradores (controlador automàtic del nivell d'oxigen dissolt al reactor biològic, ús de models descriptius del procés...) amb l'aplicació d'eines del camp de la intel·ligència artificial (sistemes basats en el coneixement, concretament sistemes experts i sistemes basats en casos, i xarxes neuronals).Aquest document s'estructura en 9 capítols diferents. Hi ha una primera part introductòria on es fa una revisió de l'estat actual del control de les EDARs i s'explica el perquè de la complexitat de la gestió d'aquests processos (capítol 1). Aquest capítol introductori juntament amb el capítol 2, on es pretén explicar els antecedents d'aquesta tesi, serveixen per establir els objectius d'aquest treball (capítol 3). A continuació, el capítol 4 descriu les peculiaritats i especificitats de la planta que s'ha escollit per implementar el sistema supervisor.Els capítols 5 i 6 del present document exposen el treball fet per a desenvolupar el sistema basat en regles o sistema expert (capítol 6) i el sistema basat en casos (capítol 7). El capítol 8 descriu la integració d'aquestes dues eines de raonament en una arquitectura multi nivell distribuïda. Finalment, hi ha una darrer capítol que correspon a la avaluació (verificació i validació), en primer lloc, de cadascuna de les eines per separat i, posteriorment, del sistema global en front de situacions reals que es donin a la depuradora / The present document wants to gather the experience obtained in the development of a Supervisory System for optimal WWTP management and control, its implementation in a real plant (Granollers WWTP) and its evaluation in the day-to-day operation with typical plant situations. This Supervisory System combines and integrates classical control of WWTP (automatic controller for maintaining a fixed dissolved oxygen level in the aeration tank, use of mathematical models to describe the process.) with the application of tools from the Artificial Intelligence field (knowledge-based systems, mainly expert systems and cased-based systems, and neural networks).This document has been structured into nine chapters. The first part is introductory with a review of the state-of-the-art in wastewater treatment control and supervision and the explanation of the complexity of WWTP management (chapter 1). This introductory chapter together with the second one, where the antecedents to the present thesis are reviewed, are good for the establishment of the objectives (chapter 3). Next, chapter 4 describes the peculiarities and specificities of the selected plant to implement the Supervisory System.Chapters 5 and 6 of the present document explain the work carried out to develop and build the knowledge base of the rule-based or expert system (chapter 6) and the case-based system (chapter 7). Chapter 8 illustrates the integration of these reasoning techniques into a distributed multi-layer architecture. Finally, there is a last chapter focused on the evaluation (verification and validation) of, first of all, each one of the techniques individually, and lately, of the overall Supervisory System when facing with real situations taking place in the wastewater treatment plant.

La implantació de Sistemes de Suport a la presa de Decisions (SSD) en Estacions Depuradores d'Aigües Residuals Urbanes (EDAR) facilita l'aplicació de tècniques més eficients basades en el coneixement per a la gestió del procés, assegurant la qualitat de l'aigua de sortida tot minimitzant el cost ambiental de la seva explotació. Els sistemes basats en el coneixement es caracteritzen per la seva capacitat de treballar amb dominis molt poc estructurats, i gran part de la informació rellevant de tipus qualitatiu i/o incerta. Precisament aquests són els trets característics que es poden trobar en els sistemes biològics de depuració, i en conseqüència en una EDAR. No obstant, l'elevada complexitat dels SSD fa molt costós el seu disseny, desenvolupament i aplicació en planta real, pel que resulta determinant la generació d'un protocol que faciliti la seva exportació a EDARs de tecnologia similar. L'objectiu del present treball de Tesi és precisament el desenvolupament d'un protocol que faciliti l'exportació sistemàtica de SSD i l'aprofitament del coneixement del procés prèviament adquirit. El treball es desenvolupa en base al cas d'estudi resultant de l'exportació a l'EDAR Montornès del prototipus original de SSD implementat a l'EDAR Granollers. Aquest SSD integra dos tipus de sistemes basats en el coneixement, concretament els sistemes basats en regles (els quals són programes informàtics que emulen el raonament humà i la seva capacitat de solucionar problemes utilitzant les mateixes fonts d'informació) i els sistemes de raonament basats en casos (els quals són programes informàtics basats en el coneixement que volen solucionar les situacions anormals que pateix la planta en el moment actual mitjançant el record de l'acció efectuada en una situació passada similar).El treball està estructurat en diferents capítols, en el primer dels quals, el lector s'introdueix en el món dels sistemes de suport a la decisió i en el domini de la depuració d'aigües. Seguidament es fixen els objectius i es descriuen els materials i mètodes utilitzats. A continuació es presenta el prototipus de SSD desenvolupat per la EDAR Granollers. Una vegada el prototipus ha estat presentat es descriu el primer protocol plantejat pel mateix autor de la Tesi en el seu Treball de Recerca. A continuació es presenten els resultats obtinguts en l'aplicació pràctica del protocol per generar un nou SSD, per una planta depuradora diferent, partint del prototipus. L'aplicació pràctica del protocol permet l'evolució del mateix cap a un millor pla d'exportació.Finalment, es pot concloure que el nou protocol redueix el temps necessari per realitzar el procés d'exportació, tot i que el nombre de passos necessaris ha augmentat, la qual cosa significa que el nou protocol és més sistemàtic. / The decision support systems (DSS) implemented in wastewater treatment plants (WWTP) make easier the application of better techniques based on the knowledge to manage the process, insuring the effluent quality and minimising the economical costs of its exploitation. The knowledge-based systems are characterised by its capability of working in ill structured domains, and with relevant information of type qualitative or uncertain. These are the characteristics that could be found in the biological systems treatments, and consequently in a wastewater treatment plant. However, the high complexity of the DSS makes very expensive their design, development and the application in a real WWTP, and because this reason it is very important the generation of a protocol that makes easier the exportation of the program to other similar plants.The objective of the present document is the development of a protocol that makes easier the systematic exportation of DSS and the reuse of the process knowledge acquired previously. The document is developed in basis on the study case from the DSS exportation from the Granollers WWTP to Montornès WWTP. This knowledge-based system integrates two kinds of systems based on knowledge, concretely the rule-based systems (which are programs that simulate the human reasoning and its capability of problem solving using the same information sources) and the case-based reasoning systems (which are informatic programs based on knowledge that solve the current abnormal situations in the plant by means of retrieving the executed action in a similar past situation).The document is structured in different chapters, in the first chapter; the lector is introduced in the DSS domain and in the wastewater treatment domain. Afterwards the objectives are defined and the materials and methods used are explained. Following, the Granollers DSS prototype is presented. Once, the prototype is explained, the first protocol made by the author in his research work is presented. Afterwards, the results obtained from the protocol application to export the DSS to other plant are presented. The real application of the protocol allows making better itself. In conclusion, the new protocol reduces the needed time to make the exportation process, although the new protocol needs more steps to make the same work, this means that it is more systematic.

Lazarus and Folkman's (1984) transactional stress-strain-coping theory provides the theoretical background for the present thesis. This theory proposes that strain (i.e., burnout) occurs when demands (i.e., work stressors) exceed coping resources (e.g., social support). The current thesis explores the influence of social support on the stress-burnout relationship in nurses. A sample of Australian nurses working across three public hospitals in Brisbane's metropolitan district were recruited to investigate the nature and level of burnout experienced by nurses. Burnout is characterised by emotional exhaustion, depersonalisation and reduced personal accomplishment. The present research addresses gaps in the empirical literature by investigating the key work stressors experienced by Australian nurses and by establishing nurses' referent levels of work stress, social support, and burnout. In addition, the research explores the complex relationships between work stress, social support and burnout. The majority of nursing studies have failed to consider how support from within the nurses' work environment mitigates burnout. The present research builds upon previous nursing literature by examining the "main&qout; and "buffering" effect hypotheses. Studies have consistently found support for the main effect model, however the hypothesis that social support buffers the negative effects of stress has resulted in highly conflicting findings. Some theorists (Cohen & Wills, 1985; Cutrona & Russell, 1990) propose that the buffering effects of social support will only be found if there is an adequate match between the needs elicited by the stressful event and the type of support an individual receives. The present study extends the stress or support matching theory by exploring the matching between specific types of stressors to specific types (i.e., emotional and instrumental) and sources (i.e.,supervisor and coworkers) of support. Cutrona (1990) suggests that the controllability of a stressor is the primary dimension in determining an appropriate match between stressors and types of support. Cutrona proposes that controllable stressful events elicit needs for instrumental support and uncontrollable events elicit needs for emotional support. Heeding Cutrona's advice, independent raters classified nurses' work stressors as controllable or uncontrollable stressful events prior to investigating the stressor-support matching theory. Three sequential studies were undertaken to explore the variables of interest to this research program. In Study 1, focus groups were conducted with 68 nurses (11 males, 34 females) from two public hospitals. The qualitative data was subjected to content analysis. The findings revealed that Australian nurses are exposed to a range of job-specific stressors (i.e., Job Conditions, Job Uncertainty, Interpersonal Conflict and a Lack of Professional Recognition and Support) and generic role stressors (i.e., Role Overload, Role Conflict and Role Ambiguity). The findings prompted the research to utilise Wolfgang's (1988) Health Professions Stress Inventory to measure nurses' job-specific stressors and Osipow and Spokane's (1987) Occupational Roles Questionnaire to measure nurses' role stressors in Study 2. The findings from Study 1 also confirmed that the way nurses perceive work support is consistent with current social support literature. Nurses indicated that their two main sources of support were their coworkers and their supervisor. Furthermore, nurses discussed social support from a multidimensional perspective, recognising different types of support that were broadly classified as emotional and instrumental support. Based on these findings, the researcher developed a work support measure specifically for the purpose of this research. Items were taken from established social support scales and were slightly modified to ensure that they were contextually relevant to nurses. In Study 2, 273 nurses (38 males, 235 females) completed a multi-measure questionnaire. While there was sufficient research evidence to indicate that the Occupational Roles Questionnaire (Osipow & Spokane, 1987) and the Maslach Burnout Inventory (Maslach, Jackson, & Leiter, 1996) possess adequate levels of reliability and validity, less was known about Wolfgang's Health Professions Stress Inventory and the work support scales designed for this research program. Factor analysis of the Health Professions Stress Inventory revealed a four-factor solution: Lack of Professional Recognition and Support, Patient Care Uncertainty, Job Conditions, and Interpersonal Conflict. Cronbach's coefficient alphas ranged from .62 to .83. Factor analysis of the Coworker Support Scale revealed a two-factor solution, representing emotional and instrumental support. Cronbach's coefficient alphas for the Emotional Coworker Support and Instrumental Coworker Support were .92 and .88 respectively. Contrary to expectations, factor analysis of the Supervisor Support Scale revealed a one-factor solution. It was therefore deemed appropriate to examine Supervisor Support as a unidimensional construct in subsequent analyses. Cronbach's coefficient alpha for the Supervisor Support scale was .96. Overall, the results from Study 2 provided supporting evidence to suggest that the measures used in the current research program were psychometrically sound. In Study 3, the data collected in Study 2 was subjected to further statistical analysis. The findings from Study 3 indicated that overall, the sample of Australian nurses reported low to moderate levels of work stress, moderate levels of work support and moderately high levels of burnout. For Emotional Exhaustion, predictor variables accounted for 42.2% of the total variance. Sociodemographic factors explained a small but significant proportion of the variance (2.7%). Work stressors however, were the main predictors of Emotional Exhaustion, explaining 41.5% of the total variance. Role Overload, Job Conditions and Role Conflict were the main determinants of Emotional Exhaustion, with Role Overload explaining most of the variance. For Depersonalisation, the predictor variables accounted for 34.2% of the total variance. Sociodemographic factors (11.5%) and work stressors (33.6%) both explained a significant proportion of the variance. Role Conflict and Patient Care Uncertainty were the main determinants of Depersonalisation, with Role Conflict explaining most of the variance. For Personal Accomplishment, Role Conflict and Role Ambiguity explained 20.5% of the total variance, with Role Conflict explaining most of the variance. Sociodemographic factors and job-specific stressors were not significant Predictors of Personal Accomplishment. Evidence for main effects of work support on burnout were limited. There was no evidence to suggest that work support had significant main effects on Emotional Exhaustion. Supervisor Support had a small, but significant main effect on Depersonalisation (â = -.15, p < .05) and Personal Accomplishment (â = -.24, p < .01). There was no evidence of main effects for Emotional and Instrumental Coworker Support. Furthermore, the present research found no significant evidence to support the buffering effect of work support on burnout. Theoretical and practical implications of these findings are discussed.

The primary aim of this diploma thesis is to describe the activities of the State Veterinary Administration of the Czech Republic (SVA) during the control of foods of animal origin and to find out the results of controls in the years 1995 to 2008. In the first part, there is solved the question of food safety in the Czech Republic (CZ) and the whole European Union (EU). In EU as well as in the CZ there exist a lot of controlling mechanisms which guarantee food safety. The second part is concentrated on the system of controls called Hygiene Supervisor, which is executed by SVA, and the analysis of the results of the controls in each year.
