In an ever-changing world, work and personal life are the main areas in which most employed adults spend their time. Today the essence of the relationship between work- and personal life is that these two domains overlap and interact. Consequently, an increasing number of employed adults are confronted with bigger demands in both their work and personal lives, and many of their daily hassles stem from job responsibilities that are incompatible with responsibilities in their personal lives. Educators' work has also become more intricate and demanding and may be one of the professions in which individuals find it difficult to combine their work and personal lives. The objective of this study was to determine how Setswana-speaking educators experienced their work-personal life interaction (WPLI), and more specifically to determine the significant domains, antecedents, consequences and strategies associated with WPLI for the participants. A non-probability purposive voluntary sample (N = 10) was taken of Setswana-speaking secondary school educators from the Potchefstroom and Klerksdorp areas in the North West Province. Data collection was done through a phenomenological method of semi-structured in-depth interviews. Data was analysed by the use of content analysis The results indicated that educators experienced factors in both their work and personal lives to be demanding. In addition, work demands led to various time constraints and strain. However, factors were identified that made the demands less overwhelming and it was also found that educators valued certain things (family, friends, leisure time, church and personal time) in their personal lives. Educators nevertheless employed certain strategies to cope with this interaction, which in turn led to numerous positive outcomes. Lastly, an interesting finding relating to this study was that educators felt a responsibility towards the children. Recommendations were made for the organisation and for future practice. / Thesis (M.Com. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2007.

Work and family constitutes the dominant life roles for most adults in contemporary society. In that, work may be interrupted by family and family may be interrupted by work. Work often generates ambivalent feelings; it can create both positive feelings (e.g. gives energy, enables development) and negative feelings (e.g. lack of freedom). Therefore, most people accept the overall life experiences including the various dimensions or domains that play a role in work-personal life interaction, such as, time spent on one domain, pressures experienced, responsibilities carried, sense of loyalty with work and family, as common and conflicting aspects. Recent developments in boundary theory highlighted the fact that integrating, or rather interaction means bordering between the two domains of work and personal life is permeable. The main objective of this study was to investigate work-personal life interaction (WPLI) experiences of Setswana speaking police officials. This study also concentrated on the existence of work-personal life interaction, aspects involved, consequences thereof and coping mechanisms employed by the police officers. A non-probability purposive voluntary sample (n = 12) was taken of Setswana speaking police officials from the Mafikeng area in the North West Province. Data collection was done through a phenomenological method of semi-structured in-depth interviews. Content analysis was used to analyse, quantify and interpret the research data systematically and objectively. Results from the content analysis based on the experiences were recorded as reported. The results indicated that there was a definite interaction between work and personal life. However, some police officials experienced interaction more than others. Furthermore, they also experienced the interaction to be more negative than positive due to organisational stressors and the management style of the organisation. Consequently the participants experienced high levels of strain and difficulty when managing their time and dealing with the interaction between their work and personal lives. The time and strain difficulties induced a lot of conflict in their homes as well as their social lives. However, there were some police officials who experienced positive aspects in their lives regardless of the difficulties of being a police official. In addition, it was identified that they made use of coping mechanisms that acted as a buffer against negative experiences of WPLI. Recommendations were made for both the organisation and for future practice. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2008.

In contemporary society, work and home represent the two most significant domains in the life of a working individual. In order to help an individual live optimally, the work and personal life domains must no longer be regarded as separate domains, but as highly interrelated. The work and personal life domains must influence each other in a positive way to assist the individual in his daily responsibilities at work and in his personal life. A high proportion of employed workers, however, have serious difficulties in combining obligations in their work and personal lives. Educators are one of the occupations that may find it difficult to integrate their work and personal life. The objectives of this research were to determine how Afrikaans-speaking educators experienced Work-Personal Life Interaction (WPLI), to determine the domains in Afrikaans-speaking educators' lives that could interact with one another, to determine the main antecedents and consequences of WPLI for Afrikaans-speaking educators and to investigate which strategies Afrikaans-speaking educators used to deal with WPLI issues. A non-probability purposive voluntary sample (N = I I) of Afrikaans-speaking secondary school educators was used from the North West Province (in the Potchefstroom and Promosa areas). A qualitative design from a phenomenological approach was used to determine educators' experience of WPLI. Content analysis was used to analyse, quantify and interpret the research data. The results indicated that educators experienced certain aspects in their work environment and personal lives as demanding. Certain dimensions were identified in both their work and personal lives. As a result of a demanding work environment, they experienced time and strain-based conflict between their work and personal lives. However, it was found that educators possessed various factors that facilitated their WPLI and strategies they used to deal with WPLI issues. Recommendations were made for the organisation and for future research. / Thesis (M.Comm. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2007.

Les Megavirales appartiennent à des familles de virus géants infectant un grand nombre d'hôtes eucaryotes. Leurs génomes ont des tailles variant de 100 kb to 2.5 mb et leur composition a montré des caractéristiques surprenantes qui ont soulevées diverses questions sur l’origine et l’évolution de ces virus. Les études de métagénomique environnementale ont montré qu’il existe une «matière noire», composée de séquences reliées à aucun organisme connu. Cependant, l'identification des séquences a été principalement réalisée en utilisant les séquences ADN ribosomal (ADNr), ce qui conduit à ignorer les virus. D’autres gènes informationnels « cœur », incluant la DNA-dependant RNA polymerase (RNAP) constituent d'autres marqueurs qui apparaissent comme plus appropriés pour une classification plus exhaustive des séquences, puisqu’ils apparaissent conservés dans les organismes cellulaires ainsi que les mégavirus. Nous avons utilisé un petit ensemble de gènes universels conservés incluant la RNAP et avons reconstruit des séquences ancestrales pour rechercher des séquences reliées aux mégavirus dans les bases de données. Cela a permis d’identifier trois nouvelles séquences de megavirus qui avaient été mal annotées comme correspondant à des organismes cellulaires, ainsi que de nouveaux clades viraux dans les bases métagénomiques environnementales. De plus, nous avons montré que l’ordre Megavirales constituait une quatrième branche monophylogénétique ou « TRUC » (pour Things Resisting Uncompleted Classification). Nos analyses montrent également que la RNAP ainsi que quelques autres gènes utilisés dans nos études permettent de considérer un répertoire plus complet d’organismes que l’ADNr. / Nucleocytoplasmic large DNA viruses (NCLDVs), or representatives of order Megavirales, belong to families of giant viruses that infect a large number of eukaryotic hosts. These viruses genomes size ranges from 100 kb to 2.5 mb and compose surprising features, which raised various questions about their origin and evolution. Environmental metagenomic studies showed that there is a “dark matter”, composed of sequences not linked to any known organism. However sequence identification was mainly determined using ribosomal DNA (rDNA) sequences, which led therefore to ignore viruses, because they are devoid of such genes. Informational genes, including DNA-dependant RNA polymerase (RNAP), are other markers that appear as more appropriate for a comprehensive classification as they are conserved in cellular organisms (Bacteria, Archaea and Eukarya) and in Megavirales. We used a small set of universally conserved genes that included RNAP and reconstructed ancestral sequences to search for megavirus relatives in sequence databases and to perform phylogeny reconstructions. This allowed identified three megaviral sequences that were misannotated as cellular orgainsms, and new viral clades in environmental databases. In addition, we delineated Megavirales as a fourth monophylogenetic TRUC (things resisting uncompleted classification) aside cellular organisms. Moreover, we classified by phylogenetic and phyletic analyses based on informational genes new giant viruses as new bona fide members of the fourth TRUC. Our analyses shows that RNAP as well as a few other genes used in our studies allow a more comprehensive overview and classification of the biological diversity than rDNA.

Nous explorons et analysons, dans cette recherche, les modes d’engagement d’enseignants qui deviennent directeur d’école. Il s’agit d’une transition personnelle et professionnelle qui a lieu dans un contexte d’évolution de l’environnement éducatif et de transformation institutionnelle. Ce passage dans de nouvelles fonctions s’accompagne souvent d’une restructuration identitaire. Au-delà de l’action, l’engagement repose sur un ensemble complexe et dynamique de conduites, d’attitudes mais aussi de processus psychoaffectifs, sociocognitifs et conatifs. Dans une approche active et plurielle de la socialisation, le modèle de l’interstructuration du sujet et des institutions (Baubion-Broye, A., Malrieu, P. & Tap, P., 1987) auquel nous nous référons, considère qu’au-delà d’influences externes et de composantes socio-biographiques, c’est bien le sujet qui reste l’agent de ses engagements. Nous montrons que les conduites d’engagement professionnel ne proviennent pas uniquement d’influences sociales ou d’intentions personnelles mais qu’elles sont orientées par des processus d’inter-signification du travail. Les origines de l’engagement se réfèrent à d’autres domaines de vie et temps d’existence pour les individus et reposent notamment surdes arbitrages de valeurs et de visées concurrentes. La recherche met à jour une typologie des trajectoires socioprofessionnelles des directeurs en trois classes, dont on mesure l’influence différentielle sur l’orientation de leurs engagements. Nos résultats indiquent comment certaines valeurs orientent les conduites et comment ces valeurs sont mises à l’épreuve quand, au cours de l’exercice professionnel, s’installe un sentiment de décalage entre attendu, prescrit et réalisé.Chaque type d’engagement apparaît comme dimension d’un projet de vie qui articule de manière singulière les visées, les ressources et les contraintes de différents domaines de vie (familial, professionnel, personnel, social). / We explore and analyze, in this research, patterns of teacher’s commitment who become principals. This is a personal and professional transition that takes place in a context of changing educational environment and institutional transformation.This passage of new features is often accompanied by a restructuring of identity. Beyond the action, the commitment is based on a complex and dynamic behavior, attitudes, but also processes psycho, socio-cognitive and conative.In an active and plural approach of socialization, the model of the subject and institutions interstructuration (Baubion-Broye, A., Malrieu, P. & Tap, P., 1987) which we refer, considers that beyond external influences and socio-biographical components, that is the subject who is the agent of its commitments.We show that the conducts of professional commitment are not confined to social influences or personal intentions but they are guided by the process of inter-service work. The origins of commitment refer to other areas of life and time of existence for individuals and based in particular on trade-offs of competing values and referred.Research updates a typology of socio-professional trajectories of directors into three classes, which we measure the differential influence on the direction of their commitments.Our results indicate how certain values drive behaviors and how these values are tested when in the course of professional practice, installs a sense of gap between expected, realized and prescribed.Each type of commitment appears as a dimension of life plan that articulates a singular way the aims, resources and constraints of different domains of life (family, professional, personal, social). / Esploriamo e analizziamo i coinvolgimenti di insegnanti che diventano direttori scolastici. Si tratta di una transizione personale e professionale che si svolge in un contesto di evoluzione educativa e di trasformazione istituzionale. Questo passaggio a nuove funzioni coincide spesso con una ristrutturazione dell'identità. Oltre all’ azione, l'impegno si basa non solo su un insieme complesso e dinamico dei comportamenti, ma anche su dei processi psico-affettivi , socio-cognitivi e conativi. In un approccio attivo e plurale della socializzazione, il modello dell’ interstructurazione del soggetto e delle istituzioni (Baubion-Broye, A., Malrieu, P. & Tap, P., 1987) alle quali ci riferiamo, ritiene che al di là di influenze esterne e di elementi socio-biografici, è al soggetto che spetta la decisione del suo impegno. Mostriamo che le linee di impegno professionale non si limitano solo alle influenze sociali o alle intenzioni personali, ma sono anche guidate dai processi d’inter-significato del lavoro. Le origini di questo impegno provengono da altri settori della vita e dai tempi di esistenza degli individui e si basano particolarmente sugli arbitraggi di valori e di ambizioni rivali. La ricerca evidenzia una tipologia delle traiettorie socio-professionali dei direttori in tre classi, di cui si misura l'influenza differenziale sulla direzione degli impegni assunti. I nostri risultati mostrano che certi valori orientano i comportamenti e che questi valori vengano testati quando, nel corso della pratica professionale, si installa un senso di discrepanza fra ciò che è atteso, previsto e realizzato. Ogni tipo di impegno appare comme una dimensione di un progetto di vita che organizza in modo singolare gli obiettivi, le risorse e gli obblighi dei diversi settori della vita (familiare, professionale, personale, sociale) / Dens la nosta recerca, qu’esploram e qu’analisam modos d’engagemen del regents que basan directùrs d’escola.
