The East Vaal area of the South African Post Office is faced with a high rate of teller absenteeism, which has been observed to be as high as 15 per cent. This adds to the cost of providing quality service to the company’s customers. The objectives of this study are to determine the factors that lead to the high rate of absenteeism in the East Vaal area and to make recommendations to the area management that could improve the attendance behaviour of the tellers in the area. To achieve these objectives, 51 questionnaires were prepared and handed out to the tellers with absenteeism rates of more than three percent in the East Vaal area to be completed. Face-to-face interviews with both the tellers and their branch managers were conducted. Absenteeism records and Employee Assistance Programme reports were also studied to collect more data. The findings highlighted lack of rewards for employees who reported for work regularly; employee illness; no recognition for good work performance; tellers receiving insufficient remuneration for their work; poor working conditions; and poor management style as the main reasons for the tellers taking unscheduled leave of absence. Based on the key findings, the main recommendations were that appropriate mechanisms for acknowledging and rewarding good work performance and attendance behaviour should be in place; a sick-leave pool system accessible to tellers should be introduced; establishment of performance evaluation and rewards for tellers; and introducing management practices which lead to a more open expression of opinion and participatory problem-solving / Business Management / Thesis (M.Tech.

Poe's "The Fall of the House of Usher," as early as 1839, reveals an uneasiness about the space of the house. Most literary scholars accept that this anxiety exists and causes some tension, since it seems antithetical to another dominant motif, that of the power of place and the home as sanctuary. My critical persona, like Poe's narrator in "The House of Usher," looks into a dark, silent tarn and shudders to see in it not only the reflection of the House of Usher, but perhaps the whole of what is "Southern" in Southern Literature. Many characters who inhabit the worlds of Southern stories also inhabit houses that, like the House of Usher, are built on the faulty foundation of an ideological system that divides the world into inside(r)/outside(r) and along numerous other binary lines. The task of constructing the self in spaces that house such ideologies poses a challenge to the characters in the works under consideration in this study, and their success in doing so is dependant on their ability to speak authentically in the language of silence and to dwell instead of to just inhabit interior spaces. In my reading of Faulkner and Warren, this ideology of division is clearly to be at fault in the collapse of houses, just as it is seen to be in the House of Usher. This emphasis is especially conspicuous in several works, beginning with Faulkner's Absalom, Absalom! and its (pre)text, "Evangeline." Warren carries the motif forward in his late novels, Flood and Meet Me in the Green Glen. I examine these works relative to spatial analysis and an aesthetic of absence, including an interpretation of silence as a mode of authentic saying. I then discuss these motifs as they are operating in Toni Morrison's Beloved, and finally take Song of Solomon as both an end and a beginning to these texts' concerns with collapsing structures of narrative and house.

Ce mémoire propose de décrire et comprendre les pratiques communicationnelles menant à la prise de décision consensuelle d’une collaboration interorganisationnelle (CI) spécifique, la Table québécoise de la sécurité routière (TQSR). Nous adoptons la perspective de la communication constitutive des organisations (CCO) développée par « l’École de Montréal » pour appréhender les dimensions constitutives de ces pratiques de communication et de ce mode privilégié de décision en CI. Après un aperçu de la littérature disponible en matière de CI et concernant la notion de consensus, nous proposons de nous concentrer sur les pratiques communicationnelles du consensus en adoptant la perspective du consensus par absence d’opposition d’Urfalino (2014). L’analyse de conversation et les principes d’une approche rhétorique sont ensuite mobilisés pour rendre compte des pratiques de communication qui permettent l’accomplissement du consensus lors d’une séance plénière du troisième cycle de travail de la TQSR, spécifiquement consacrée à la rédaction de son rapport final. Nous verrons que 1) les pratiques communicationnelles mobilisées facilitent l’arrêt de la décision et que 2) celles-ci sont constitutives du consensus qui favorise l’unité du collectif de collaboration. / This thesis aims at describing and understanding the communication practices that sustain the consensual decision-making of an interorganizational collaboration (CI) collective, the “Table québécoise de la sécurité routière” (TQSR). We adopt a communication constitutive of organization (CCO) approach, as developed by the “Montréal School,” to understand the constitutive dimensions of these practices. After an overview of the available literature on CI and consensus decision-making, we propose to adopt the perspective of “consensus by non-opposition” developed by Urfalino (2014) to focus on the communicative practices that sustain this decision-making process. Conversation analysis and principles of a rhetorical approach are combined to analyze a plenary session from the TQSR third cycle of work, specifically aimed at drafting the collective’s final report. This analysis allows us to identify and discuss 1) the communication practices used to facilitate the consensus decision-making process and 2) the constitutive effects of consensus as it upholds the collective of collaboration’s unity.

Dans la première partie, nous présentons les résultats de l'étude du supraconducteur sans inversion de symétrie LaRhSi3 par spectroscopie muonique. En champ nul, nous n'avons pas détecté de champ interne. Ceci indique que la fonction d'onde de l'état supraconducteur n'est pas dominée par l'état triplet. Les mesures en champ transverse de 35G présentent une transition en accord avec la transition de phase attendue sous le champ critique Hc1. Nous avons répété ces mesures pour un champ entre Hc1 et Hc2, 150G. Le spectre obtenu pour ces mesures conserve l'asymétrie et relaxe rapidement à basse température tel que prédit pour un supraconducteur dans la phase d'Abrikosov. Néanmoins, les relaxations produites par ce balayage en température présentent une transition à près de 2 fois la température critique attendue. Dans la deuxième partie de ce mémoire, nous donnons l'interprétation des résultats de la diffraction neutronique inélastique par l'étude des champs électriques cristallins. Ces mesures ont été effectuées sur des aimants frustrés SrHo2O4 et SrDy2O4 sous la forme de poudre. L'étude des niveaux produits par les champs cristallins par la méthode des opérateurs de Stevens indique une perte du moment cinétique dans les deux matériaux. Pour le SrDy2O4, l'état fondamental serait constitué de quatre états dégénérés quasi accidentellement qui portent un moment magnétique total non-nul. Toute fois, nos mesures de susceptibilité magnétique ne montrent aucun ordre au-dessus de 50mK. Pour le SrHo2O4, le fondamental est formé d'une paire accidentelle. Nous obtenons un moment magnétique de 6.94(8)$\mu_B$ ce qui s'accorde avec les données expérimentales. / In the first part of this thesis, we present our muon spectroscopy results of the non-centrosymmetric superconductor LaRhSi3. Zero magnetic field measurements showed no internal field, suggesting at most a very small triplet component in the superconducting wave function. A temperature scan taken in 35G transverse-field geometry showed a phase transition at Hc1. The asymmetry of the muon relaxation spectrum measured at 20mK and field of 150G, which is between the lower and upper critical fields, shows a faster relaxation rate compared to the spectrum obtained at 4K, a behaviour expected in the presence of vortices in the type II superconductor. However, the temperature dependence of the relaxation rate begins to increase all the way to a temperature twice Tc of LaRhSi3 in a field of 150G. In the second part of this document, we present the interpretation of inelastic neutron scattering by crystalline electric fields. These measurements were carried out on powder samples of frustrated quantum magnets SrHo2O4 and SrDy2O4. Using Stevens operators method, we determined the level scheme du to crystalline electric field effects using a point charge model and fitted it to the experimental data. For the SrDy2O4 we found a ground state that appears to be composed of four quasi-accidental degenerate states that carry a non zero magnetic moment even though susceptibility measurements did not indicate magnetic order above 50mK. For the SrHo2O4, the ground state is a pair with a 6.98(8)$\mu_B$ magnetic moment. This lat value fots with experimental data.

Essay 1 (with Oskar Nordström Skans): This paper provides field evidence on the causal impact of past successes on future performances. Since persistence in success or failure is likely to be linked through, potentially time-varying, ability it is intrinsically difficult to identify the causal effect of succeeding on the probability of performing well in the future. We therefore employ a regression discontinuity design on data from professional golf tournaments exploiting that almost equally skilled players are separated into successes and failures half-way into the tournaments (the “cut”). We show that players who (marginally) succeeded in making the cut substantially increased their performance in subsequent tournaments relative to players who (marginally) failed to make the cut. This success-effect is substantially larger when the subsequent (outcome) tournament involves more prize money. The results therefore suggest that past successes provide an important prerequisite when performing high-stakes tasks. Essay 2: Recent experimental evidence suggests that women in general are more discouraged than men by failures which potentially can explain why women, on average, are less likely than men to reach top-positions in firms. This paper provides the first quasi-experimental evidence from the field on this issue using data from all-female and all-male professional golf tournaments to see if this result can be replicated among competitive men and women. These top-performing men and women are active in an environment with multiple rounds of competition and the institutional set-up of the tournaments makes it possible to causally estimate the effect of the result in one tournament on the performance in the next. The results show that both male and female golfers respond negatively to a failure and that their responses are virtually identical. This finding suggests that women’s difficulties in reaching top-positions in firms are caused by external rather than internal barriers. Essay 3: Voting is a fundamental human right. Yet, individuals that are younger than 18 do typically not have this right since they are considered uninformed. However, recent evidence tentatively suggests that the political knowledge of youths is endogenous to the voting age. I test for the existence of such dynamic adjustments utilizing voting age discontinuities caused by Swedish laws. I employ a regression discontinuity strategy on Swedish register data to estimate the causal effect of early age voting right on political knowledge around age 18. The results do not support the existence of positive causal effects of early age voting right on political knowledge. Thus, we should not expect that 16-year-olds respond by acquiring more political knowledge if they are given the right to vote. This finding weakens the case for a lowering of the voting age from 18 to 16. Essay 4 (with Lena Hensvik): We postulate that firms’ production losses  from absence depend on the employees’ internal substitutability, incentivizing firms to keep absence low in positions with few substitutes. Using Swedish employer-employee data we show that absence is substantially lower in such positions even conditional on establishment and occupation fixed effects. The result reflects sorting on both entry and exit margins, with stronger separations responses when it was difficult to predict the absence of the employees beforehand. These findings highlight that internal substitution insures firms against production disruptions caused by absence and that absence costs are important aspects of firms’ hiring and separations decisions.

This undertaking is justified in the measure that the search for the original meaning of a text which is inspired by God and is the bearer of a universal message of salvation can favor reflection on one of the problems that most disturbs the human conscience: human suffering and faith in a God who is omnipotent and filled with benevolence. Due to the particular position of this poem [at the start of the section of the Psalter which proportionally speaks most of human suffering] and certain stylistic traces [the striking comparison at the beginning of the poem; the name of God mentioned 22 times; the tetragram in the middle of it to call attention to a particular attitude of the person praying] this research has as a hypothesis that these Psalms throw some light on the subject of God s presence in the lives of people who suffer. In the style of commentary, the research continues following the steps of synchronic analysis with some reference to diachronic analysis when necessary. It analyzing the literary beauty and certain cultural, historical and theological aspects of one of the sacred texts which was chosen as a model of prayer for Israel because it deals with one of the vital problems of the human being in a realistic and beautiful manner. As a result of this work five essential elements were discovered which appear to contribute towards reflection on the presence of God next to the suffering human person: 1) the importance of trust in God; 2) how the presence of God appears to be experienced as absence; 3) worship as a privileged manner of communication and communion with God; 4) the misunderstanding of God as one of the causes of the difficulty to deal with suffering; 5) confining the presence of God to only the Temple in Jerusalem as a theological limitation of this poem / A presente dissertação tem como objetivo apresentar um estudo exegético de um poema bíblico: Sl 42 43. Tal empreendimento se justifica na medida em que a busca pelo sentido original de um texto, que foi inspirado por Deus e é portador de uma mensagem universal de salvação, possa favorecer a reflexão sobre um dos problemas que mais perturba a consciência humana: o sofrimento humano e a crença em um Deus cheio de bondade e onipotente. Dada a singular posição deste poema encabeça a parte do Saltério que, proporcionalmente, mais fala de sofrimento humano e certos indícios estilísticos a impactante comparação no início do poema, o nome de Deus citado 22 vezes, o tetragrama no centro do poema para chamar a atenção a uma determinada atitude do orante esta pesquisa tem como hipótese que estes Salmos lançam alguma luz sobre a questão da presença de Deus junto ao ser humano sofredor. No estilo de comentário, a pesquisa avança seguindo os passos de uma análise sincrônica com acenos à diacronia, quando necessário, analisando a beleza literária e certos aspectos culturais, históricos e teológicos de um dos textos sagrados que foi escolhido como modelo de oração para Israel por ele tratar de um dos problemas vitais do ser humano de maneira realista e bela. Como resultado deste trabalho foram encontrados cinco elementos essenciais que parecem contribuir na reflexão sobre a presença de Deus junto ao ser humano que sofre, a saber: 1) a importância da confiança em Deus; 2) o modo da presença de Deus parece ser sua ausência sentida; 3) o culto como uma maneira privilegiada de comunicação e comunhão com Deus; 4) a incompreensão de Deus como uma das causas da dificuldade de se lidar com o sofrimento; 5) o confinamento da presença de Deus apenas ao Templo de Jerusalém como uma limitação teológica deste poema

With the advent of Law no. 9249/95, and consequently with the possibility of extinguishing punishment of authors of crimes against the tax order, after the effective payment of the helpless taxes, some controversies arose regarding the coercive effectiveness of Criminal Law. However, it is observed a differentiated treatment of non-taxable offenders, hence the importance of analyzing the instituting of punishment and acquittals in another perspective. Given that the Brazilian prison population is large, mainly due to practices of crimes against the patrimony, it is searched with the present work, to analyze the fact of the equal application of the benefit given to the authors of the crimes against the tax order, also to the authors of other crimes, who may repent of the criminal practice, restoring the injured object or, in its impossibility, repairing, in a certain way, the damage caused. Equal treatment is proposed between offenders, observing the possibility of extinguishing punishment, with an eye towards reducing new criminal practices, as well as reducing the prison population, generating a possibility of saving for the state, since it will not be obliged to costing the maintenance of the prisoners, a benefit for the victim, since they will be compensated for the damage caused by the practice of the crime, and a possibility of a second chance for the perpetrator, who will not be incarcerated. The analysis was based on bibliographical research, having as sources the doctrine, technical productions and jurisprudences. At first, the importance of taxes was analyzed for the maintenance of state activities, conceptualizing and extracting the purpose of the taxes, in order to understand the need to classify crimes against the tax order, and consequent application of a penalty to the offender. In a second moment, it is sought to understand the beneficent institutes of the Later Regret (Later Repentance) and the Acquittal Excuse (Excusive Absence). And then, the possibility of equal treatment and possible benefits, with the application of the abovementioned institutes, against the State, the victim and the aggressor was evaluated. / O Princípio da Igualdade deverá ser utilizado em todas as situações que envolvam relações jurídicas. Com o advento da Lei nº9.249/95, e, consequentemente, com a possibilidade da extinção de punibilidade aos autores de crimes contra a ordem tributária, após o efetivo pagamento dos tributos sonegados, surgiram algumas controvérsias no tocante à eficácia coercitiva do Direito Penal. Contudo, observa-se um tratamento diferenciado para com os autores de infrações que não tenham cunho tributário, daí a importância da análise dos institutos da extinção de punibilidade e das escusas absolutórias, numa outra ótica. Dado que a população carcerária brasileira encontra-se vultuosa, principalmente devido a práticas de crimes contra o patrimônio, busca-se com o presente trabalho, analisar o fato da aplicação equiparada do benefício dado aos autores dos crimes contra a ordem tributária, também aos autores de outros crimes, que porventura venham a se arrepender da prática delituosa, restituindo o objeto lesado, ou, na sua impossibilidade, reparando, de certa forma, o dano causado. Propõem-se um tratamento igualitário entre os infratores, observando a possibilidade da extinção da punibilidade, com olhos voltados à redução de novas práticas delituosas, bem como na diminuição da população carcerária, gerando uma possibilidade de economia para o estado, pois não será obrigado a custear a manutenção dos presos, um benefício para a vítima, vez que será ressarcida do prejuízo causado pela prática do crime, e uma possibilidade de segunda chance para o autor, que não será encarcerado. A análise se fundamentou em pesquisas bibliográficas, tendo como fontes a doutrina, produções técnicas e jurisprudências. Num primeiro momento foi analisado a importância dos tributos para a manutenção das atividades estatais, conceituando e extraindo a finalidade dos tributos, para se entender a necessidade da tipificação de crimes contra a ordem tributária, e consequente aplicação de uma pena ao infrator. Num segundo momento busca-se entender os institutos benéficos do Arrependimento Posterior e da Escusa Absolutória. E em seguida foi avaliado a possibilidade do tratamento igualitário e eventuais benefícios, com a aplicação dos institutos acima mencionados, frente o Estado, a vítima e o agressor.

I en sjöfartsfamilj kretsar mycket av vardagen kring de olika perioderna i sjöfararens yrke - hemmaperioder, bortaperioder och perioderna kring hemkomst och avresa. Det finns undersökningar på hur sjöfararen och dennes partner upplever dessa perioder men det saknas kunskap om hur det är att växa upp i en sjöfartsfamilj. Mot denna bakgrund var syftet med denna undersökning att undersöka hur unga vuxna, uppväxta i en sjöfartsfamilj med en periodvis bortavarande sjöfarare, upplevt perioderna när sjöfararen var hemma, borta och kring avresa eller hemkomst. En kvalitativ metod användes och åtta semistrukturerade intervjuer med åtta respondenter gjordes. Respondenternas upplevelser varierade men en övergripande känsla var att perioderna av lång sammansatt ledighet när sjöfararen var hemma övervägde nackdelarna med att bara ha en förälder under bortaperioderna. Under sjöfararens bortavaro upplevde alla respondenterna varierande grader av saknad, framförallt vid speciella tillfällen eller högtider, men för många var det en normalitet då de inte kände till något annat. / In a seafaring family a considerable part of everyday life revolves around the different periods of the seafarers working cycle - when the seafarer is home, away and the periods just before and after leaving or coming home. There are studies on how seafarers and their partners experience these periods, but very little on what it’s like to grow up in a seafaring family. Against that background, the purpose of this study was to examine how young adults, brought up in a seafaring family with an intermittently absent parent, have experienced the different periods connected to the seafarers working cycle. The study used a qualitative method and it comprised of eight semi structured interviews with eight respondents. The respondents’ experiences varied but the overall sentiment was that the seafarers long leave periods made up for the disadvantages of only having one parent while the seafarer was away. All respondents reported feeling varying degrees of sadness when the seafarer left and having feelings of longing around holidays and special occasions. Many respondents referred to it as a normality and that it was all they knew.

The goal of the Master Thesis is to analyse the performance Eraritjaritjaka created by the leading director of German experimental theatre Heiner Goebbels. The first part exposes the new theatrical genre Théâtre musical as a theoretical framework. The following text focuses on Goebbels's theoretical views and the basics characetrs of his theatre poetics. The main part of this study is devoted to analysis of performance Eraritjaritjaka. The analysis itself focuses on the functioning of basic components of the performance, its principles and shifts in overall structure.
