Narcissism och syskonplacering hos gymnasieelever

Pham, Denise, Ekberg, Pernilla January 2008 (has links)
Abstract The aim of this present study was to investigate whether there is a relationship between birth order and the personality trait narcissism using 181 individuals from Finnveden High School in Värnamo (115 females, 60 males, mean age 17, sd=0,94), in the context of the proposal of Sulloway (1996) that personality is influenced by the specialized nich-es siblings adopt in the quest for access to parental resources. A questionnaire which in-cludes Narcissistic Personality Inventory test, Birth order test and also Rosenberg’s self-esteem test in order to investigate if it might has an impact on narcissistic personality trait, was used. Results showed that there was no significant relationship between birth order and narcissism, however, a significant relationship between narcissism and self-esteem was found. Furthermore, there was a significant relationship between narcissism and the individual’s relationship with the mother. In conclusion, there was no direct rela-tionship between birth order and narcissism. Our hypothesis was falsified and no support for Sulloways theory was found.

Computation of Molecular Properties at the Ab Initio Limit

Temelso, Berhane 16 January 2007 (has links)
The accuracy of a quantum chemical calculation inherently depends on the ability to account for the completeness of the one- and n-particle spaces. The size of the basis set used can be systematically increased until it reaches the complete one-particle basis set limit (CBS) while the n-particle space approaches its exact full configuration interaction (FCI) limit by following a hierarchy of electron correlation methods developed over the last seventy years. If extremely high accuracy is desired, properly correcting for very small effects such as those resulting the Born-Oppenheimer approximation and the neglect of relativistic effects becomes indispensable. For a series of chemically interesting and challenging systems, we identify the limits of conventional approaches and use state-of-the-art quantum chemical methods along with large basis sets to get the “right answer for the right reasons.” First, we quantify the importance of small effects that are ignored in conventional quantum chemical calculations and manage to achieve spectroscopic accuracy (agreement of 1 cm−1 or less with experimental harmonic vibrational frequencies) for BH, CH+ and NH. We then definitively resolve the global minimum structure for Li₆ , Li₆⁺ , and Li₆- using high accuracy calculations of the binding energies, ionization potentials, electron affinities and vertical excitation spectra for the competing isomers. The same rigorous approach is used to study a series of hydrogen transfer reactions and validate the necessary parameters for the hydrogen abstraction and donation steps in the mechanosynthesis of diamondoids. Finally, in an effort to overcome the steep computational scaling of most high-level methods, a new hybrid methodology which scales as O(N⁵) but performs comparably to O(N⁶) methods is benchmarked for its performance in the equilibrium and dissociation regimes.

Inversion des formes d'onde élastique dans le domaine espace-fréquence en deux dimensions.<br />Application à la caractérisation de la subsurface dans le cadre de la détection de cavités souterraines.

Gélis, Céline 14 December 2005 (has links) (PDF)
L'imagerie des paramètres physiques du sous-sol à partir d'enregistrements sismiques de surface constitue un problème inverse non linéaire. L'inversion des formes d'onde élastique est une méthode d'imagerie quantitative multiparamètres de diffractants, nécessitant au préalable la connaissance précise d'un macromodèle de vitesse. <br /><br />Le problème direct associé, la propagation des ondes élastiques, est résolu dans le domaine fréquentiel, permettant la prise en compte efficace d'acquisitions multisources et multirécepteurs, par une méthode numérique de différences finies modélisant la propagation de tous les types d'onde (ondes de volume, de surface, diffractées, réfractées ...). Le stencil de différences finies choisi permet simule précisément la surface libre et la propagation des ondes de surface. <br /><br />Cette inversion linéarisée s'appuie sur une méthode de gradient, qui minimise une fonction coût contenant les différences entre données observées et calculées. Deux paramètres sismiques sont reconstruits à partir de sismogrammes verticaux et horizontaux. L'inversion est effectuée des basses fréquences vers les hautes fréquences, introduisant des longueurs d'onde de plus en plus courtes dans les images des paramètres. Ces dernières sont sensibles au choix des approximations physiques effectuées pour calculer le gradient de la fonction coût (approximation de Born ou de Rytov), au dispositif d'acquisition, au préconditionnement des données et au choix des paramètres inversés. <br /><br />Cette méthode est ensuite appliquée à des milieux contenant une surface libre. La surface libre est une interface très contrastée qui donne lieu à des ondes de surface très énergétiques dans les sismogrammes. Les milieux de subsurface sont complexes, les ondes qui s'y propagent subissent des réflexions ou diffractions multiples. Lorsque le milieu contient deux anomalies dont le contraste en vitesse vaut $20 \%$, l'inversion les localise correctement dans un macromodèle connu. Les images sont améliorées et l'amplitude des anomalies est très bien reconstruite lorsque le nombre de fréquences inversées augmente et les données sont sélectionnées des faibles déports vers les grands déports. Avec une anomalie fortement contrastée comme une cavité vide, l'inversion retrouve correctement la position, la forme et la taille de l'objet mais son amplitude est sous-estimée.<br /><br />L'application à des données réelles verticales de subsurface acquises dans un milieu complexe contenant une cavité maçonnée montre que le milieu hétérogène issu de l'inversion ajuste mieux les données et permet de bien reproduire les ondes inversées. Néanmoins, la cavité n'est pas imagée.

探討天生全球化企業之因素-以中國中小企業為例 / The factors of Born Globals: Take Chinese SMEs for example

徐素圓, Hsu, Su Yuan Unknown Date (has links)
全球經濟穩定成長帶動企業國際化,並對中國企業對外發展提供強烈支持,而國際企業的型態也隨著貿易障礙下降而不斷演變成各式樣貌,企業逐漸改變傳統早期的漸進式國際化發展階段,而演變為自企業創立之初即具備全球化經營能力的天生全球化企業(Born Globals),這股新興國際企業型態在開發中國家的形成過程,對國際企業理論與學術研究而言是重要且值得探討的議題。 過去研究對於天生全球化企業的定義目前未有一致之認知,且對其形成因素也有多種不同看法,然而相對於大多數學者專注的已開發國家天生全球化企業發展過程,本研究則是以開發中國家之中小企業作為主要研究對象,並期望透過探討中國中小企業是否存在部分可能變數,來瞭解其企業內外部可能影響企業發展為天生全球化企業之因素。 本文透過文獻探討歸納出研發能力、產品品質、經營能力與電子商務參與程度等四變數為天生全球化企業之可能形成原因,並蒐集128家中小企業作為研究對象,以邏輯迴歸作為研究方法,分析此四變數對於企業在發展成天生全球化企業的過程中是否會產生影響,以釐清天生全球化企業在開發中國家的發展過程。 研究結果顯示,擁有較好研發能力與經營能力的企業較有機會發展成天生全球化企業,且企業愈快加入電子商務市場,愈有助於企業早期國際化發展,本文期望藉由此驗證結果提供開發中國家中小企業在發展天生全球化企業時一些參考與建議。 / International enterprises has evolved to different types as the global environment changed. From 1990s, some enterprises begin their overseas business right at birth or near the founding year, which is quite different to traditional enterprises, and we call these enterprises as Born Globals. Why Born Globals can start their international business at the time they just established still not come to a conclusion today. Therefore this paper is trying to figure out the possible factors which encourage the enterprises, especially the small and medium enterprises in China, to develop the early abroad business. This study generated four possible factors of R&D, managerial competence, product quality and e-commerce adoption to analyze the possibility of Born Globals. And I collected 128 sample firms to exam my hypotheses. The final results showed that there are positive effectiveness between R&D, managerial competence and Born Globals, and the fast speed of e-commerce market adoption also advance firms becoming Born Globals. However, product quality did not show benefit to Born Globals in the results.

Telefonrådgivning till utlandsfödda vårdsökande - en utmaning i tiden : en intervjustudie om distriktssköterskors erfarenheter

Hagelin Bäcklund, Cecilia, Kantergård, Therese January 2015 (has links)
Bakgrund: Telefonrådgivning på vårdcentral utgör en stor del av distriktssköterskors arbete. När distriktssköterskor saknar visuell kontakt med vårdsökare i telefonen ställs andra krav på kommunikationen mellan distriktssköterskor och vårdsökande. I takt med den ökade invandringen i Sverige träffar distriktssköterskor på utlandsfödda vårdsökande med språkförbistring i allt större utsträckning. Det behövs därför mer forskning inom detta område. Syfte: Syftet med denna studie är att beskriva distriktssköterskors erfarenheter av telefonrådgivning på vårdcentral till vårdsökande som inte har svenska som modersmål. Metod: Designen på studien är en kvalitativ deskriptiv intervjustudie med induktiv ansats. Datamaterialet utgjordes av tio intervjuer med distriktssköterskor på vårdcentral. Analys gjordes med hjälp av kvalitativ innehållsanalys. Resultat: Ur analysen framträder fyra kategorier Att främja samspel i kommunikationen, Att träffa på svårigheter/ hinder i samtalet, Att använda organisatoriska strategier, Att använda sin kompetens. Slutsats: Att nå överensstämmelse i kommunikationen ansågs som något av det viktigaste i arbetet med telefonrådgivning.  Kulturella skillnader och språkförbistring gjorde telefonrådgivningen utmanande. Andrahandsinformation gjorde det svårt att veta att korrekt information gavs samt att sekretessen upprätthölls. Distriktssköterskorna beskrev oro för felbedömning vid samtal med uppringare med språkförbistring. Att förmedla trygghet ansågs viktigt vid telefonrådgivning till utlandsfödda vårdsökare. Distriktssköterskorna i studien eftersökte organisatoriskt stöd och utbildning för att lättare kunna arbeta med telefonrådgivning. / Background: Telephone advice and triage at health care centers constitutes a big part of the daily tasks a district nurse perform. As the tele nurses lacks visual contact with their patients, there are greater demands in the communication as opposed to face-to-face encounters. As the immigration increases in Sweden, the district nurse encounters an increasing amount of foreign born callers with language barriers. Therefore, more research in this area is necessary. Aim: The aim of this study is to describe distric nurses experiences of telephone nursing to healthcare seekers with other native language than Swedish. Method: The study design is a qualitative descriptive interview study with an inductive approach. Data was collected through ten individual interviews with district nurses in health center and the data was analyzed by content analysis. Results: Four categories emerged from the analysis: To encourage synergetic communication, To encounter obstacles in the conversation, To practice organizational strategies, To utilize one's competence. Conclusion: To pursue mutuality in communication and to conclude a common decision was seen among the most important aspects of the telephone nursing advisory. Cultural differences and language barriers caused the telephone nursing to become a challenging task for the nurses. Secondary information received through friends and relatives introduced an uncertainty to determine information correctness and whether the secrecy remained upheld. The district nurses expressed concern of misjudgment during conversations with callers who showed language inabilities. To bring security was noted as crucial in telephone nursing for foreign born callers. Furthermore, the district nurse needs to be confident in oneself. The district nurses in this study sought for organizational support and education.

Origin and role of social networks : a Comparative study of Born Global Firms of France and Pakistan

Akhter, Manzoom 05 July 2013 (has links) (PDF)
Network approach is more appropriate measure to describe the early internationalization of born global firms. The focus of our research is to investigate the origin, structure and role of social networks in the early internationalization of born global firms. We intend to investigate the structure of networks which is considered pre-requisite to study the other dimensions of network ties. Many researchers directly jump to study the role networks play without paying any attention from where these ties originate. Furthermore, much of the literature has connected the born global firms with high technology sector however, there are many examples of born global firms in traditional sectors. Similarly, very little is known about how various national context influence the internationalization process of firms. Therefore, we also intend to investigate network ties in the context of different industrial sectors and different level of country's institutional development by comparing born global firms from France and Pakistan.Our results reveal that these small born global firms use their networks to overcome the constraints to rapid internationalization which has been supported by previous empirical findings. The results also reveal that origin of ties is in both business-social or non-business social settings. Both weak and strong ties are found to have positive impact on the early internationalization; however composition of ties is different in low-tech and high-tech firms. We also argue that instead of country's level of institutional development, composition of ties is moderated by the industrial sector in which firm is operating.

The Formation and Development of Chinese Communities in Atlanta, Augusta, and Savannah, Georgia: From Sojourners to Settlers, 1880-1965

Bronstein, Daniel Aaron 29 April 2009 (has links)
The study examines the formation and development of Chinese American populations in Augusta, Savannah, and Atlanta, Georgia from the beginnings of Chinese Exclusion period through the passage of the Immigration Act of 1965. Although people of Chinese ancestry were in an ambiguous position upon their arrival in the 1880s within the black-white dyad that defined southern race relations, they were able to negotiate this system, transforming themselves from being perceived as “outsiders” before the 1940s to being treated as “honorary whites” by the late 1960s. To explore this transition, this project analyzes generational differences between immigrants and their children. Before the 1920s, the mostly Chinese immigrant male population concerned themselves with establishing viable businesses for sending remittances back to family in China and creating social institutions that helped the men cope with decades of separation from their families. The men avoided possible conflict with Jim Crow by having their businesses and residences in black or immigrant areas. Some men cultivated better relations with whites by attending Sunday schools that catered to Chinese immigrants. The mutation from “outsider” to “honorary white” status began when prosperous Chinese men started sending for wives to join them in the 1910s, thus ushering in a new pattern of planned long-term settlement in the state. Families successfully challenged the older perception by joining white churches, enrolling their children in white schools, and building social ties with white community leaders. Second generation Chinese Americans reaped the benefits of this strategy in the 1950s and 1960s by gaining access to housing in white neighborhoods, employment opportunities in white-collar occupations, and acceptance as partners in marriages with European Americans.

The constitutional and contractual implications of the application of chapter 19 of the Children's Act 38 of 2005

Lewis, Samantha Vanessa January 2011 (has links)
In this research, I carefully and coherently examine Chapter 19 of the Children's Act 38 of 2005 as the first legislation to afford surrogate motherhood agreements legal recognition in South Africa. I argue that the application of Chapter 19 imposes a number of unwarranted limitations on several of the constitutional rights of the parties to a surrogacy agreement. In addition, I propose that Chapter 19 is not in accordance with the principal of the best interests of the child. I examine the history of surrogate motherhood in South Africa and establish that, prior to the enactment of Chapter 19, no legislation expressly afforded surrogate motherhood agreements legal recognition. Hence, prior to the enactment of Chapter 19, parties who entered surrogacy agreements could, first, not rely on the agreement to enforce contractual obligations, and secondly, the legal positions of the parties to the agreement were uncertain. Thirdly, a child born of a surrogacy agreement was seen as the child of the surrogate mother and not of the commissioning parents.
