Förvärv av goodwill : En studie av svenska noterade företags rörelseförvärv / Acquisition of goodwill : A study of Swedish listed companies' business acquisitions

Larsson, Andreas January 2015 (has links)
Bakgrund: Sedan IFRS infördes år 2005 har goodwill fått en allt mer betydande roll i svenska börsnoterade företag. Idag utgör goodwill majoriteten av köpeskillingen vid rörelseförvärv, vilket går emot grundtanken hos de nuvarande redovisningsstandarderna. Redovisningen av rörelseförvärv enligt IFRS ger företagsledningen stor frihet att använda sitt egna omdöme. Detta har av många påpekats ger plats för opportunistiskt agerande och möjligheter för företag att strategiskt kunna fördela större summor till goodwill. Syfte: Syftet med denna studie är att undersöka huruvida företagens skuldsättningsgrad, storlek och lönsamhet påverkar andelen av köpeskillingen som allokeras till goodwill vid rörelseförvärv. Vidare är syftet att undersöka om företagsledningen i svenska noterade bolag agerar opportunistiskt vid köpeskillingallokeringen i samband med rörelseförvärv. Metod: För att uppnå studiens syfte har en kvantitativ metod använts. I studien undersöks  194 rörelseförvärv gjorda av företag noterade på Large Cap och Mid Cap under perioden 2011-2014. Detta gjordes för att undersöka sambandet mellan företagens skuldsättningsgrad, storlek och lönsamhet och andelen av köpeskillingen som allokeras goodwill. Detta har testats med hjälp av regressionsanalyser. Resultat och slutsats: Studiens resultat visar att företag med lägre lönsamhet tenderar att fördela en större andel av köpeskillingen till goodwill jämfört med företag med högre lönsamhet. Resultatet påvisar även att mindre företag tenderar att allokera en större andel av köpeskilling till goodwill jämfört med större företag. Studien finner dock enbart svaga belägg för att skuldsättningsgrad kan vara en påverkande faktor. Resultatet ger följaktligen indikationer på att företagsledningen agerar opportunistiskt i samband med köpeskillingsallokeringen. / Background: Since adopting IFRS in 2005, goodwill has gained an increasingly significant role in Swedish listed companies. Today, goodwill makes for the majority of the purchase price in business acquisitions, which goes against the basic idea of the current accounting standards. Accounting for business acquisitions under IFRS gives management greater discretion and more room to use their own judgement. This has been pointed out by many to provide room for opportunistic behavior and the opportunity for companies to strategically allocate larger sums to goodwill. Purpose: The purpose of this paper is to examine whether the companies’ leverage, size and profitability affect the percentage of the purchase price allocated to goodwill. Furthermore, the purpose is to examine whether managers in Swedish listed firms act opportunistically in the case of purchase price allocation associated with business acquisitions. Method: To achieve the purpose of the study a quantitative method is used. This study examined 194 business acquisitions made by companies listed on the Large Cap and Mid Cap during the period 2011-2014. This was done to examine the correlation between firm leverage, size and profitability and the proportion of the purchase price allocated to goodwill. This has been tested using regression analysis. Results and conclusion: The results of the study show that companies with lower profitability tend to allocate a greater proportion of the purchase price to goodwill compared with companies with higher profitability. The results also show that smaller companies allocate a larger proportion of the purchase price to goodwill compared with larger companies. The study finds, however, only weak evidence that leverage can be an influencing factor. These results therefore provide indications that management uses their discretion to act opportunistic in the purchase price allocation process.

Effects of scaling and grain structure on electromigration reliability of Cu interconnects

Zhang, Lijuan, 1979- 11 February 2011 (has links)
Electromigration (EM) remains a major reliability concern for on-chip Cu interconnects due to the continuing scaling and the introduction of new materials and processes. In Cu interconnects, the atomic diffusion along the Cu/SiCN cap interface dominates the mass transport and thus controls EM reliability. The EM lifetime degrades by half for each new generation due to the scaling of the critical void volume which induces the EM failure. To improve the EM performance, a metal cap such as CoWP was applied to the Cu surface to suppress the interfacial diffusion. By this approach, two orders of magnitude improvement in the EM lifetime was demonstrated. For Cu lines narrower than 90 nm, the Cu grain structure degraded from bamboo-like grains to polycrystalline grains due to the insufficient grain growth in the trench. Such a change in Cu grain structures can increase the mass transport through grain boundaries and thus degrade the EM performance. The objective of this study is to investigate the scaling effect on EM lifetime and Cu microstructure, and more importantly, the grain structure effect on EM behaviors of Cu interconnects with the CoWP cap compared to those with the SiCN cap only. This thesis is organized into three parts. In the first part, the effect of via scaling on EM reliability was studied by examining two types of specially designed test structures. The EM lifetime degraded with the via size scaling because the critical void size that causes the EM failure is the same with the via size. The line scaling effect on Cu grain structures were identified by examining Cu lines down to 60 nm in width using both plan-view and cross-sectional view transmission electron microscopy. In the second part, the effect of grain structure was investigated by examining the EM lifetime, statistics and failure modes for Cu interconnects with different caps. A more significant effect of the grain structure on EM characteristics was observed for the CoWP cap compared to the SiCN cap. For the CoWP cap, the grain structure not only affected the mass transport rate along the Cu line, but also impacted the flux divergence site distribution which determined the voiding location and the lifetime statistics. Finally, the effect of grain structure on EM characteristics of CoWP capped Cu interconnects was examined using a microstructure-based statistical model. In this model, the microstructure of Cu interconnects was simplified as cluster and bamboo grains connected in series. Based on the weakest-link approximation, it was shown that the EM lifetime and statistics could be adequately modeled by combining the measured cluster length distribution with the EM lifetime-cluster length correlation for each individual failure unit. / text

Communautés d’apprentissage professionnelles : conditions d’implantation mises en place par deux directrices d’école élémentaire

Génier, Éric 09 April 2013 (has links)
La présente recherche tente d’identifier et de décrire les conditions d’implantation qui ont été mises en place dans deux écoles élémentaires francophones de l’Ontario pour atteindre un stade de fonctionnement avancé, soit l’intégration (Leclerc, Moreau et Lépine, 2009a) des communautés d’apprentissage professionnelles (CAP). En utilisant un échantillon de directions d’école et d’enseignants qui travaillent à l’intérieur d’écoles où les CAP sont à un tel stade de fonctionnement, notre recherche a permis de relever quelles conditions ont été mises en place pour atteindre un fonctionnement avancé des CAP. Des entrevues semi-dirigées ont été menées auprès de deux directrices et de quatre enseignantes d’écoles élémentaires franco-ontariennes. Ces entrevues abordaient de grands thèmes tels que la structure des CAP, la culture de collaboration et les processus employés en CAP dans le contexte de l’école. Un questionnaire sur le sentiment d’efficacité personnelle fut aussi rempli par les directrices d’école. Les résultats mettent en évidence le rôle complexe de la direction d’école dans la mise en œuvre des CAP tout en précisant les conditions d’implantation des CAP mises de l’avant par deux directrices d’école. En fait, nous relevons l’importance de recevoir des appuis humains et financiers et un soutien par la recherche; d’instaurer des exigences organisationnelles « préparatoires »; de respecter des exigences organisationnelles de mise en place des CAP; d’assurer que la direction et les membres du conseil scolaire aient confiance et soient compétents; d’instaurer un leadership partagé entre la direction, le conseil scolaire et les enseignants du comité d’amélioration du rendement des élèves (CARE); de rédiger des objectifs SMART à partir de ressources particulières et aménager un parcours de fonctionnement; d’établir des structures physiques et d’encourager une culture de collaboration entre les enseignants. Les résultats de notre étude rejoignent ce qu’avancent les recherches au sujet de l’implantation de la structure organisationnelle – CAP – dans une école. Or, notre recherche sur le terrain permet d’apporter des précisions quant à ces conditions d’implantation. D’ailleurs, nous avons recensé certaines sous-catégories thématiques qui ne sont pas reflétées explicitement dans la littérature.

Emissions Policy in Canada: Past Failures and Future Promises

Huff, Mathew 16 October 2014 (has links)
Climate change represents a challenging problem in public policy. This project examines various policy solutions to rising emissions, and suggests one that might be best suited to Canada, a highly-integrated, highly-developed economy which relies on natural resources, including fossil fuels, for its balance of payments, governmental revenues, and a small portion of its GDP. It adopts a public policy framework from Simpson, Rivers and Jaccard (2008) to analyze policy solutions using the following criteria: political acceptability, economic efficiency, administrative feasibility and effectiveness at reducing emissions. Additionally, it offers substantial discussion relating to the potential constraints and opportunities to climate change policy presented by NAFTA, compliance with which is key to the viability of any emissions regime. It advocates an upstream cap-and-trade system, integrated with the NAFTA area and regulated by an empowered Commission for Environmental Cooperation (CEC), as well as complementary policies to lower emissions in inelastic sectors. / Graduate / mat.huff@gmail.com

The Prime-and-Realign Process of the Influenza A Virus Occurs to Rescue Cap-Snatched Primers on the Basis of Length and RNA Duplex Stability

De Vlugt, Corey 05 December 2018 (has links)
Cap-snatching by the influenza A virus (IAV) RNA-dependant RNA polymerase (RdRp) is driven by the abundance of transcripts being actively transcribed by host RNA polymerase II (Pol II)[1]–[3]. Deviations from a direct correlation with abundance do arise, due to selective cleavage of transcripts with a compatible length (10 to 13 nucleotides) and nucleotide sequence (ending in 3’AG)[4]–[7]. Some cap-snatched primers are not directly used to transcribe mRNA, but instead undergo a prime-and-realign mechanism (PAR). As of yet it is unknown why this process occurs. My hypothesis is that the prime-and-realign process is related to the physical characteristics of the primers and their interactions with RdRp and the vRNA template. Here, I used four published deep sequencing datasets of the 5’ ends of IAV mRNA obtained from IAV infected A549 cells to examine PAR[1], [7]–[9]. Primers are biased towards PAR on the basis of length (<12 nucleotides) and RNA duplex stability (mediated by the base directed at 3’U1 and the pyrimidine-purine base pair at position four). PAR typically adds a GCA addition resulting in a primer three nucleotides longer ending in a compatible nucleotide sequence with 3’U1. Prime-and-realign converts poor primers on the basis of length and sequence compatibility with the 3’ end of the vRNA into one that can efficiently undergo transcription of the critical conserved sequence without errors, or failure. Prime-and-realign, therefore, affords tremendous flexibility to RdRp in cap snatched primer length and sequence compatibility.

Entre essas novas figuras, os interventores, destacamos o Capitão João Punaro Bley: um outsider que chega ao Espírito Santo em um período de transformações, sem nenhum reconhecimento da população que estaria à frente, e ainda assim, consegue manter-se no poder local por mais de doze anos. Através de fotografias veiculadas na revista ilustrada Vida Capichaba durante quatro anos marcantes de seu governo (1930, 1935, 1937 e 1942), espera-se encontrar rastros de como essas imagens podem ser consideradas ferramentas de controle político utilizadas por Bley para disseminar sua imagem, e conquistar o apoio da sociedade espírito-santense. Serão analisadas as relações entre fotografia e história, além de um panorama geral do contexto da época, e da revista Vida Capichaba como veículo de destaque dentro da sociedade em se encontrava.

No. of bitstreams: 1 tese_4663_.pdf: 1799679 bytes, checksum: ead9f316260b4faa5f087c62c3ed5b7b (MD5) Previous issue date: 2011-02-15 / A finalidade deste estudo foi investigar, à luz da Sociolinguística Variacionista, a variação morfossintática ausência/presença de artigo definido antes de antropônimos e possessivos no Português falado na cidade de Vitória (ES), a fim de delimitar, em última instância, a tendência capixaba para esse aspecto morfossintático, estabelecendo-o como (um) traço de identidade linguística dentro do cenário nacional. Buscou-se entender quais fatores influenciam a alternância entre a presença e a ausência do artigo definido diante antropônimos, em construções como totalmente diferente de Æ Isabela/tava tendo o casamento do meu tio Nim, e possessivos, em enunciados do tipo mora Æ minhas tias... os meus tios.... Tomando como referência os trabalhos de Silva (1982, 1996a, 1996b) e Callou e Silva (1997), foram selecionadas para esta amostra vinte entrevistas realizadas pelo Projeto PORTVIX (Português falado na cidade de Vitória/ES) com 20 falantes capixabas. Os principais resultados obtidos por meio do tratamento estatístico dos dados no Programa VARBRUL foram gerados em duas etapas separadas. Na primeira etapa de testes, que diz respeito aos antropônimos, num conjunto total de 300 ocorrências e um percentual global de uso do artigo definido em torno de 39%, o programa apontou quatro grupos como sendo os mais significativos do ponto de vista estatístico, na seguinte ordem de seleção: gênero do antropônimo, traços supra-segmentais, faixa etária e gênero do falante. No que concerne ao contexto dos pronomes possessivos, em um total de 1016 ocorrências e um percentual global de uso do artigo em torno de 33%, o programa selecionou os grupos ausência/presença e tipo de preposição, tipo do possessivo e outras formas, natureza do possuído, nível de escolaridade e gênero do falante como os mais significativos. Em linhas gerais, os resultados apontam que, em termos de percentuais globais de uso do artigo, os capixabas da cidade de Vitória (ES) usam menos artigo do que outras regiões do país. Esse percentual foi de 39%, no contexto dos antropônimos, e 33% no contexto de pronomes possessivos, o que alinha a capital do Espírito Santo, no contexto dos antropônimos, com o Rio de Janeiro (43%). Por outro lado, no contexto do possessivo, não há comparação razoável, haja vista que Vitória (ES) está consideravelmente afastada das demais capitais brasileiras inventariadas até o momento: as cidades de Recife e Salvador, que apresentam os menores índices, estão na casa dos 60% contra apenas 33% da capital capixaba. Destarte, a tendência à ausência do artigo definido parece configurar-se como uma marca identitária inconsciente na capital capixaba.

A concepção de uma arquitetura pedagógica (AP) acontece com a definição de objetivos de aprendizagem (o que aprender), atividades (o que fazer), método (como fazer) e recursos digitais (com o que fazer). Este trabalho apresenta a construção de uma plataforma, denominada CAPCOM, que permite criar arquiteturas pedagógicas que envolvam o uso de operações cognitivas, de forma individual ou colaborativa, sobre dados multimídia. A proposta inicial é que esses dados multimídia tenham sido criados em atividades de campo. O trabalho apresenta seis arquiteturas pedagógicas, com os respectivos recursos digitais, criadas para validar a plataforma CAPCOM. Além disso, são apresentados resultados da validação da plataforma CAPCOM com a criação e uso de novas APs, envolvendo 2 professores e 5 alunos do IFES. No desenvolvimento da plataforma são adotados conceitos propostos no projeto MOrFEU (Multi-Organizador Flexível de Espaços Virtuais), acerca de desenvolvimento de software, arquiteturas pedagógicas, configuração flexível de recursos digitais e ambientes flexíveis para aprendizagem
