Har branschtillhörighet en påverkan på aktieåterköp? : En kvantitativ studie om aktieåterköp i olika branscher på den svenska marknaden

Sarhangi, Diana, Lindqvist, Tove January 2020 (has links)
Den 10 mars 2000 blev det lagligt för publika aktiebolag att köpa tillbaka sina egna aktier i Sverige. Företag har därefter tagit tillfället i akt och använt detta distributionssätt. Denna studie syftar till att undersöka huruvida det finns skillnader i olika branscher gällande aktieåterköp under tidsperioden 2011–2019. Branscherna som studerades var industri, läkemedel, fastigheter, dagligvaror och telekommunikation. Undersökningen utfördes för att se om branschtillhörighet hade en inverkan på företag som använder sig av aktieåterköp. Samtliga företag som ingår i undersökningen är noterade på Nasdaq OMX Stockholm, Large-Cap. Studien använde en kvantitativ metod med en deduktiv ansats. Ett hypotestest utfördes som sedan prövades med en regressionsanalys för att se om det fanns signifikanta skillnader på aktieåterköp i olika branscher. Resultatet påvisade att det inte fanns några signifikanta branschskillnader, och branschtillhörighet har därför ingen inverkan på huruvida ett företag använder sig av aktieåterköp. Resultatet i denna studie går i linje med Higgins (1972) studie The corporate dividend-saving decision som menade att valet av utdelningspolitik inte påverkas av branschen företaget befinner sig i. / On March 10, 2000, it became legal for public limited companies to buy back their own shares in Sweden. Companies have since taken the opportunity and used this method of distribution. This study aims to examine whether there are differences in different industries regarding share repurchases during the period 2011-2019. The industries studied were pharmaceuticals, real estate, industry, consumer goods and telecommunications. The survey was conducted to see if industry affiliation had an impact on companies that use share repurchases. All companies included in the survey are listed on Nasdaq OMX Stockholm, Large-Cap. The study used a quantitative method with a deductive approach. A hypothesis test was performed which was then tested with a regression analysis to see if there were significant differences in share repurchases in various industries. The results showed that there were no significant industry differences, and industry affiliation therefore has no effect on whether a company uses share repurchases. The results of this study are in line with Higgins' (1972) study the corporate dividend-saving decision, which stated that the choice of dividend policy is not affected by the industry the company operates in.

The value of human rights on the open market: Liberal economic policies and the achievement of personal integrity rights.

Harrelson-Stephens, Julie 12 1900 (has links)
At the end of World War II, the United States emerged as a world leader, putting into place international institutions based on its own liberal economic philosophy. Since then, the world has witnessed an increasing interconnectedness among states, with economic relationships continually blurring the distinction between domestic and international, as well as between state and societal forces. Much of the world associates this increased interconnectedness with human suffering around the globe. This dissertation seeks to test the effects of economic globalization on personal integrity violations within a state, on the whole. Specifically, I examine three aspects associated with globalization, trade openness, investment and IMF funding within a state. Liberal economic theory suggests that economic relationships should foster positive gains. Particularly, economic relationships engender economic prosperity, diffusion of norms and idea, as well as the growth of a middle class which increasingly demands respect for its political and civil rights. Consistent with the liberal paradigm, I find that open trade and investment lead to improved personal integrity rights. In addition, investment which originates from the hegemon is especially likely to increase a state's respect for personal integrity rights. Conversely, IMF funding is likely to provoke protests from people in recipient countries, which often leads to increased repression by the state. To the extent that the IMF chooses to place importance on human rights, future attention should be paid to the practices of recipient countries. Overall, this dissertation suggests overall support for the liberal paradigm, that open economic policies are most likely to lead to improved levels of personal integrity rights.

Listeria monocytogenes em queijo minas meia cura: análise quantitativa, qualitativa e perfil molecular das cepas isoladas / Listeria monocytogenes in Minas meia cura cheese: quantitative analysis, qualitative and molecular characterization of isolates

Raimundo, Daniele Cristine 06 March 2013 (has links)
O queijo minas meia cura, popular entre os consumidores no Brasil, não é regulamentado, o que pressupõe que estes produtos sejam de origem informal, fabricados com leite cru, sem controle das condições higiênicas e sanitárias ou do processo de cura. Esta pesquisa se dispôs a estudar os fatores, tanto relacionados ao queijo (pH, Aw e U%) quanto aos relacionados à Listeria monocytogenes (análise qualitativa, quantitativa nas amostras que forem positiva e identificação e caracterização genotípica) como também pesquisar possível atividade antagônica das bactérias lácteas sobre a Listeria monocytogenes.Foram analisadas 165 amostras provindas de barracas de feiras do município de São Paulo. As análises físico-químicas classificaram as amostras como queijo de média umidade (57,6%) e de baixa umidade (34,5%); quanto ao pH, o valor mínimo registrado foi de 4,3 e o máximo foi de 7,5; e os valores da Aw variaram de 0,86 a 0,98. Listeria monocytogenes foi isolada em 3% das amostras (5/165) pelo método qualitativo, enquanto os testes de quantificação (feitos nas amostras positivas) não revelaram o agente, sugerindo que o nível de contaminação apresentava-se entre os limites de detecção das técnicas, a saber: 1 UFC/25g ou 0,04 UFC/g para a qualitativa e 3 NMP/g para a quantitativa . Em ambas as técnicas de caracterização genotípica (AFLP e PFGE) foram gerados cinco pulsotipos, cada um representando uma amostra. De 480 colônias isoladas das amostras, 6,66% apresentaram antagonismo pela L. monocytogenes. A freqüência de Listeria monocytogenes em queijo tipo minas meia cura é relativamente baixa e, quando presente, encontra-se em baixos níveis de contaminação. No entanto, do ponto de vista geográfico, o agente encontra-se no queijo tipo minas meia cura de todas as regiões do município de São Paulo. / Minas meia-cura cheese, popular among brazilian consumers, has not been regulated indicating that the cheese available in the market is informal and made from raw milk, uncontrolled hygienic-sanitary conditions nor the curing process. This study aimed evaluating factors related to the product (pH, Aw and U%) as well as the ones related to Listeria monocytogenes (qualitative analysis followed by quantitative analysis of the positive ones and genetic identification). Antagonic activity of some lactic bacteria against Listeria monocytogenes was also investigated. Samples (165) were bought at open markets in São Paulo city. By the content in humidity, samples were classified as cheese of medium (57,6%) and low humidity (34,5%); concerning pH the lowest value was 4,3 and the highest 7,5, values of Aw ranged from 0,86 a 0,98. Listeria monocytogenes was isolated from 3% of the samples (5/165) by qualitative test but none of them showed any growth in quantitative test suggesting that the level of contamination were somewhere in between the detection limits of the tests: 1 CFU/25 g or 0,04 CFU/g for qualitative method and 3 MPN/g for quantitative one. In both genotypic characterization techniques (AFLP and PFGE) five pulsotypes were generated, each one representing a sample. Of 480 colonies isolated from the samples, 6.66% showed antagonism by L. monocytogenes. The frequency of Listeria monocytogenes in Minas meia cura cheese is relatively low and when present the level of contamination is low. However it is wide distributed in Sao Paulo city.

Pesquisa de Salmonella spp. em queijos Minas meia-cura obtidos em feiras livres da cidade de São Paulo / Recovery of Salmonella spp. in Minas meia-cura cheese from open markets of the Sao Paulo city

Pedrosa, Felipe Roberto Vita 13 December 2010 (has links)
O queijo tipo Minas, quando curado, desenvolve características específicas que têm grande aceitação no mercado nacional. Isto, associado ao fato de ser um queijo de fácil fabricação e que tem bom valor agregado, estimula a produção informal, com o uso do leite cru e com tempo de cura de 10 a 12 dias; o que não atende o tempo mínimo que a legislação exige para que se use o leite cru. Este projeto se propôs a pesquisar a presença de Salmonella spp. em 161 amostras de queijo Minas meia-cura comercializado informalmente na cidade de São Paulo; em 32 amostras foram pesquisados a Aw, umidade e pH. Todas as amostras foram negativas para Salmonella spp. em 25g e os valores médios de umidade, Aw e pH foram, respectivamente, de 29,92, 0,94 e 5,1. Conclui-se que o risco de se contrair salmonelose pelo consumo desse produto é menor do que era esperado, embora não tenha sido pesquisada a presença de células viáveis mas não cultiváveis. No entanto, deve-se ter em mente que a ausência de controle da cadeia produtiva desse queijo é um fator de risco para outros perigos, seja de natureza microbiológica, química, física e de fraudes. / The curing of Minas type cheese develops specific characteristics that are accepted by the consumers. This, together with the facts that Minas type cheese is easy to be made and has a good added value encourage informal production, using raw milk and 10 to 12 days of curing; this period does not meet the minimum required by law in case of using raw milk. This study aimed to investigate the presence of Salmonella spp. in 161 samples of Minas meia-cura cheese informally sold in Sao Paulo open markets; Aw, moisture and pH were analyzed in 32 samples. All samples were negative for Salmonella spp. in 25g and the average values for moisture content, Aw and pH were, respectively, 29,92, 0,94 and 5,1. It is concluded that the risk of having salmonelosis by eating this product is lower than expected, although the presence of viable but nonculturable cells had not been evaluated. However, the lack of control throughout the chain production of this cheese is a risk factor for other hazards, whether of microbiological, chemical or physical origin, besides frauds.

Pesquisa do Estado da Bahia - FAPEB / Estuaries and coastal regions are widely used environments for the disposal of urban and industrial effluents, causing contamination of waters and marine life by several pollutants, among them trace elements, considered as one of the most important contaminants, and may be associated with Organic and inorganic solids in the aquatic environment. In the Bay of All Saints (BTS) region, despite the pockets of contamination in the rivers and estuaries that feed it, fishing activities are intense and rely on a variety of fish, including fish, crustaceans and mollusks that are intended for subsistence Of riverside communities or to commerce in surrounding cities, such as the municipality of Feira de Santana-BA. As a result, this study aimed to identify the commercialization dynamics of fish in the free fairs of Feira de Santana-BA and to evaluate the concentration of trace elements in shrimps (Litopenaeus vannamei) from the BTS. For this, a research was initially conducted at the free fairs of Feira de Santana to identify the most traded species at fairs and their origin. The results identified that the most popular species at the fairs are: tilapia (Oreochromis niloticus), corvinas (Micropogonias furnieri) and shrimps (Litopenaeus vannamei) respectively, but only crustaceans and molluscs originate from BTS fishing communities. The analysis of trace element concentrations performed later with Litopenaeus vannamei showed high levels of Fe and Mn in the tissues, but only Cr and Pb levels exceeded the limits of ANVISA for inorganic contaminants in foods. Significant differences were found between the exoskeleton and muscle tissues and between stages of young and adult maturity. / Os estu?rios e as regi?es costeiras s?o ambientes muito utilizados para a disposi??o de efluentes urbanos e industriais, acarretando a contamina??o das ?guas e da vida marinha por diversos poluentes, dentre eles os elementos tra?os, considerados como uns dos contaminantes mais importantes, podendo estar associados a s?lidos org?nicos e inorg?nicos no meio aqu?tico.

Although we found that stock prices did not respond to buyback programs in the period 2006 to 2012 (1.65% cumulative abnormal returns after 5 days), the average stock price reaction in 2008 (2.93%) is higher and different with statistical significance. Furthermore, we found that the share price reaction from companies with market capitalization below R$10 billion is higher than the one from larger companies. In addition, we found that the response to the buyback programs is positively correlated (i) to the company’s purchasing activity after the announcement, (ii) to the maximum amount of shares announced which can be bought and (iii) to the quantity actually bought during the program. This research is unique in providing empirical evidence on the Brazilian case by analyzing 377 programs announced during that period. The research also confirms that the stock reaction is not influenced by the company's purchasing activity in prior announcements. / Este artigo avalia empiricamente a eficácia dos programas de recompra de ações como instrumento de sinalização de preços baixos durante a crise de 2008 no Brasil com base em 377 programas de recompra. Os resultados não confirmam que o instrumento sinaliza conforme evidenciado pela reação dos preços das ações período entre 2006 e 2012 (1,65% de retornos anormais cumulativos depois de 5 dias), mas por outro lado, o diferença no impacto médio no preço das ações em 2008 (2,93%) é significativo estatisticamente. Além disso, ao segmentar a amostra entre empresas de baixo e alto valor de capitalização, há evidência empírica que as ações de empresas com baixa capitalização são mais sensíveis ao anúncios de recompra. Com base em dados ex-ante, mostramos que se a empresa realmente informa que poderá fazer volumes grandes de recompra, as ações tendem a ajustar o seu preço de forma estatisticamente significativa. Há evidências que o impacto no preço da ação não é influenciado por recompras realizadas em programas anteriores.
