Entry, re-location and growth in the Swedish wholesale trade industry

Wholesale trade has an intermediate position between manufacturing and retail in the distributional channel. In modern economies, consumers buy few, if any, products directly from manufacture or producer. Instead, it is a wholesaler, who is in direct contact with producers, buying goods in larger quantities and selling them in smaller quantities to retailers. Traditionally, the main function of a wholesaler has been to push goods along the distributional channel from producer to retailer, or other nonend user. However, the function of wholesalers usually goes beyond the process of the physical distribution of goods. Wholesalers also arrange storage, perform market analyses, promote trade or provide technical support to consumers (Riemers 1998). The existence of wholesalers (and other intermediaries) in the distributional channel is based on the effective and efficient performance of distribution services, that are needed by producers and other members of the supply chain. Producers usually do not enjoy the economies of scale that they have in production, when it comes to providing distributional services (Rosenbloom 2007) and this creates a space for wholesalers or other intermediaries. Even though recent developments in the distributional channel indicate that traditional wholesaling activities now also compete with other supply chain organizations, wholesaling still remains an important activity in many economies (Quinn and Sparks, 2007). In 2010, the Swedish wholesale trade sector consisted of approximately 46.000 firms and generated an annual turnover of 1 300 billion SEK (Företagsstatistiken, Statistics Sweden). In terms of turnover, wholesaling accounts for 20% of the gross domestic product and is thereby the third largest industry. This is behind manufacturing and a composite group of firms in other sectors of the service industry but ahead of retailing. This indicates that the wholesale trade sector is an important part of the Swedish economy. The position of wholesaling is further reinforced when measuring productivity growth. Measured in terms of value added per employee, wholesaling experienced the largest productivity growth of all industries in the Swedish economy during the years 2000 through 2010. The fact that wholesale trade is one of the important parts of a modern economy, and the positive development of the Swedish wholesale trade sector in recent decades, leads to several questions related to industry dynamics. The three topics that will be examined in this thesis are firm entry, firm relocation and firm growth. The main question to be answered by this thesis is what factors influence new firm formation, firm relocation and firm growth in the Swedish wholesale trade sector?

A therapy dog's impact on daytime activity and night-time sleep for older persons with Alzheimer's disease : a case study

Background: Animal-Assisted Therapy using dogs have been described as having a calming effect, decrease sundowning and blood-pressure in persons with Alzheimer’s disease. The aim was to investigate how continuous and scheduled visits by a prescribed therapy dog affected daytime and night-time sleep for persons with Alzheimer’s disease. Methods: In this case study, registration of activity and sleep curves was conducted from five persons with moderate to severe Alzheimer’s disease living at a nursing home, over a period of 16 weeks using an Actiwatch. Data was analysed with descriptive statistics. Result: The study shows no clear pattern of effect on individual persons daytime activity and sleep when encounter with a therapy dog, but instead points to a great variety of possible different effects that brings an increased activity at different time points, for example during night-time sleep. Conclusions: Effects from the use of a Animal-Assisted Therapy with a dog in the care of persons with Alzheimer’s disease needs to be further investigated and analysed from a personcentred view including both daytime and nightime activities.

Predator Survival Tactics and Use of Habitat Cover in Rana Catesbeiana.

Predator-prey relationships are an important aspect of the natural world, and, because of its relevance to survival and natural selection, is an interesting relationship to study. In amphibian larvae, level of activity and landscape use are often what determines the survival as prey. I studied the anti-predator behavior of the North American bullfrog (Rana catesbeiana) tadpoles when presented with dragonfly (Aeshna) larvae, a known predator of tadpoles. Tadpoles were acclimated to four different habitats with varying degrees of habitat cover, and were transferred to a new habitat with a degree of cover equal to one of the acclimation tanks. A restrained predator, and thus its chemical cue, was introduced, and the behavior, particularly the use of the habitat cover to hide from the perceived risk of predation was observed. A significantly higher frequency of inactivity was found in tank I than in II and III, and inactivity followed a general trend of decreasing with increasing habitat cover. Difference in tank cover was not found to have a significant effect on swimming behavior, but did have a significant effect on hiding behavior, which increased with higher availability. Foraging decreased significantly with the addition of a predator, but did not vary significantly with different levels of cover. Hiding behavior and reducing conspicuous behaviors (like foraging) are probably the behaviors that afford the tadpole the most success at eluding a predator in their natural environment.

Trabalhadores na reciclagem do lixo : dinâmicas econômicas, sócio-ambientais e políticas na perspectiva de empoderamento

Esta pesquisa enfoca as dinâmicas econômicas, sócio-ambientais e políticas de organização, construção da identidade coletiva e empoderamento de trabalhadores em associações de reciclagem, levando-se em conta suas relações com diversos agentes externos. A escolha desse objeto do estudo prende-se a dois aspectos principais: - à caracterização dessa atividade como uma ocupação em estruturação e processo de reconhecimento, representando uma possibilidade de sustentabilidade e autonomia para setores da população de baixa renda em países em desenvolvimento; - a uma situação peculiar de relação entre Estado e sociedade, na qual as associações de catadores/recicladores interagem simultaneamente com órgãos dos governos municipais respectivos, do governo estadual e com entidades não-governamentais, como setores da Igreja Católica e ONGs nacionais e internacionais. Através da análise comparativa das características de três associações de reciclagem na Região Metropolitana de Porto Alegre, verificam-se resultados diferenciados no que diz respeito a processos internos de organização do trabalho e de participação nas decisões, bem como em relação às percepções, motivações e expectativas dos catadores/recicladores quanto a sua ocupação.

Novel catalyst systems based on Ni(II), Ti(IV), and Cr(III) complexes for oligo-and polymerization of ethylene

The complex of Brookhart Ni(α-diimine)Cl2 (1) (α-diimine = 1,4-bis(2,6- diisopropylphenyl)-acenaphthenediimine) has been characterized after impregnation on silica (S1) and MAO-modified silicas (4.0, 8.0 and 23.0 wts.% Al/SiO2 called S2, S3 and S4, respectively). The treatment of these heterogeneous systems with MAO produces some active catalysts for the polymerization of the ethylene. A high catalytic activity has been gotten while using the system supported 1/S3 (196 kg of PE/mol[Ni].h.atm; toluene, Al/Ni = 1000, 30ºC, 60 min and atmospheric pressure of ethylene). The effects of polymerization conditions have been tested with the catalyst supported in S2 and the best catalytic activity has been gotten with solvent hexane, MAO as cocatalyst, molar ratio Al/Ni of 1000 and to the temperature of 30°C (285 kg of PE/mol[Ni].h.atm). When the reaction has been driven according to the in situ methodology, the activity practically doubled and polymers showed some similar properties. Polymers products by the supported catalysts showed the absence of melting fusion, results similar to those gotten with the homogeneous systems by DSC analysis. But then, polymers gotten with the transplanted system present according to the GPC’s curves the polydispersity (MwD) varies between 1.7 and 7.0. A polyethylene blend (BPE/LPE) was prepared using the complex Ni(α-diimine)Cl2 (1) (α-diimine = 1,4-bis(2,6-diisopropylphenyl)-acenaphthenediimine) and {TpMs*}TiCl3 (2) (TpMs* = hydridobis(3-mesitylpyrazol-1-yl)(5-mesitylpyrazol-1-yl)) supported in situ on MAO-modified silica (4.0 wts. -% Al/SiO2, S2). Reactions of polymerization of ethylene have been executed in the toluene in two different temperatures (0 and 30°C), varying the molars fraction of nickel (xNi), and using MAO as external cocatalyst. To all temperatures, the activities show a linear variation tendency with xNi and indicate the absence of the effect synergic between the species of nickel and the titanium. The maximum of activity have been found at 0°C. The melting temperature for the blends of polyethylene produced at 0 °C decrease whereas xNi increases indicating a good compatibility between phases of the polyethylene gotten with the two catalysts. The melting temperature for the blends of polyethylene showed be depend on the order according to which catalysts have been supported on the MAO-modified silica. The initial immobilization of 1 on the support (2/1/S2) product of polymers with a melting temperature (Tm) lower to the one of the polymer gotten when the titanium has been supported inicially (1/2/S2). The observation of polyethylenes gotten with the two systems (2/1/S2 and 1/2/S2) by scanning electron microscopy (SEM) showed the spherical polymer formation showing that the spherical morphology of the support to been reproduced. Are described the synthesis, the characterization and the catalytic properties for the oligomerization of the ethylene of four organometallics compounds of CrIII with ligands ([bis[2-(3,5-dimethyl-1-pyrazolyl)ethyl]amine] chromium (III) chloride (3a), [bis[2-(3,5- dimethyl-l-pyrazolyl)ethyl]benzylamine] chromium (III) chloride (3b), [bis[2-(3,5-dimethyl-lpyrazolyl) ethyl]ether] chromiun(III)chloride (3c), [bis[2-(3-phenyl-lpyrazolyl) ethyl]ether]chromiun(III)chloride (3d)). In relation of the oligomerization, at exception made of the compounds 3a, all complex of the chromium showed be active after activation with MAO and the TOF gotten have one effect differentiated to those formed with CrCl3(thf)3. The coordination of a tridentate ligand on the metallic center doesn't provoke any considerable changes on the formation of the C4 and C6, but the amount of C8 are decrease and the C10 and C12+ have increased. The Polymers produced by the catalyst 3a to 3 and 20 bar of ethylene have, according to analyses by DSC, the temperatures of fusion of 133,8 and 136ºC respectively. It indicates that in the two cases the production of high density polyethylene. The molar mass, gotten by GPC, is 46647 g/mols with MwD = 2,4 (3 bar). The system 3c/MAO showed values of TOF, activity and selectivity to different α-olefins according to the pressure of ethylene uses. Himself that shown a big sensibility to the concentration of ethylene solubilized.

Structural Transformation and Productivity in Latin America

We investigate the role of sectorial differences in labor productivity and the process of structural transformation (reallocation of labor across sectors) in accounting for the time path of aggregate productivity across six Latin American countries (Brazil, Chile, Argentina, Colombia, Mexico and Venezuela) from 1950 to 2003. We used a general equilibrium model with three sectors (agriculture, industry and services) calibrated to those six economies. The model is used to compare the trajectory of productivity in each sector of activity with that of the United States and it impact on aggregate productivity.While in Brazil and Argentina, the Service Sector was responsible for reversing the process of catch up in productivity that occurred until the 1980s, in others, like Colombia, Mexico and Venezuela, low productivity growth of the three sectors explain their poor performance.

O controle externo sobre as agências reguladoras de Estado : limites e (im)possibilidades

Com a criação das primeiras entidades reguladoras de infraestrutura, década de 90, surgiu uma nova maneira estratégica de o Estado atuar com intuito de melhorar a governança pública. O Estado brasileiro, que era responsável direto pelo desenvolvimento econômico e social, buscou se redefinir frente ao modelo de entidades reguladoras que emergia. Em decorrência dessa nova fisionomia estatal, a descentralização funcional ganhou ênfase resultando no aparecimento de estruturas mais flexíveis e autônomas sob a natureza de direito público com a finalidade de atuar em setores típicos de Estado. Assim, foram criadas as primeiras agências reguladoras brasileiras com objetivo de normatizar, incentivar e regular setores essenciais à sociedade. Por consequência de tais inovações, diversas áreas administrativas tiveram de serem adaptadas, sobretudo as relacionadas à atividade de controle no âmbito administrativo. Para tanto, tornou-se necessário conciliar, dentro de um escopo sistematizado, mecanismos capazes de atender as demandas oriundas do recente Estado regulador brasileiro. Com efeito, a função controle adquire relevo no sentido de evitar que tais agências reguladoras apartem-se de limites impostos por lei ou de que divirjam de suas missões institucionais. Assim, o presente trabalho investiga a atuação do controle externo exercido pelo Tribunal de Contas da União (TCU) no desempenho das agências reguladoras de Estado. Diante de o assunto permear várias áreas epistemológicas, entende-se que abordá-lo sob o enfoque interdisciplinar pode estender em contribuições sobre o objeto investigado. Nesse contexto, esta dissertação visa incorporar, também, outras áreas de conhecimento. Longe de defender um isomorfismo para o arranjo regulatório brasileiro ou de promover uma saída paradigmática, esta pesquisa busca, com amparo na metodologia qualitativa e sob os enfoques exploratórios e descritivos, reunir conhecimentos e constatações no sentido de propiciar maior aproximação acerca do assunto e concorrer para o delineamento de diretrizes futuras do controle externo sobre a regulação brasileira. Destaca-se que tanto a regulação como o controle sobre o ambiente regulatório são assuntos que se encontram em desenvolvimento no contexto brasileiro, o que enseja a pertinência desta pesquisa. Em face do exposto, esta dissertação visa investigar o estado atual do controle exercido pelo TCU sobre o desempenho nas agências reguladoras de Estado – infraestrutura - com intuito de analisar e promover um debate sobre limites e (im)possibilidades dessa atuação.

O envolvimento do departamento de compras no processo de contratação de serviços profissionais

A teoria sobre a atividade de Compras argumenta que as empresas deveriam delegar para esta área a atividade de adquirir insumos e serviços. O objetivo é obter competitividade sem perder a qualidade, através da competência e especialidade desta área. Em muitas empresas, esta área não é envolvida em todas as situações de processos de contratação. Poucos artigos e trabalhos publicados estudam a relação do cliente interno com o Departamento de Compras. Esta tese de doutorado tem como objetivo identificar os problemas que interferem no envolvimento do departamento de Compras, em processos de aquisição de serviços profissionais. A Teoria da Agência é utilizada como suporte teórico, por ser uma relação de um Principal, o cliente interno, e um Agente, o departamento de Compras. As hipóteses testadas verificaram se o envolvimento do Departamento de Compras difere por categoria de Compras e se tem relação com as premissas da Teoria da Agência. A pesquisa quantitativa teve 519 respostas de empresas nacionais e multinacionais no Brasil, de diversos setores da Economia. (367 de clientes internos e 152 de profissionais de Compras). Escalas utilizadas em trabalhos anteriores foram validadas, e os dados foram analisados a partir dos resultados da Análise de variância e de Regressão múltipla. O questionário foi disponibilizado na internet para os clientes internos do Departamento de Compras, com objetivo de focar nas razões do não envolvimento do departamento. Os resultados indicam que, na percepção dos clientes internos o envolvimento do departamento de Compras difere por tipo de serviço profissional. A relação entre as dimensões de envolvimento com as premissas da Teoria da Agência foi confirmada. As respostas recebidas dos profissionais de Compras confirmam que as percepções sobre o envolvimento do departamento de Compras diferem, ao comparar com as respostas dos clientes internos. A contribuição teórica foi de utilizar a Teoria da agência para estudos de problemas na cadeia de suprimentos, além da validação das escalas e a produção de pesquisa especificamente em categorias não relacionadas à produção. No campo gerencial, os resultados obtidos explicam a relação existente entre as quatro dimensões do envolvimento e a Teoria da Agência e são apresentadas as diferenças do envolvimento pela categoria a ser contratada.

The establishment mode choise of German multinational enterprises in Brazil: a comparative approach

We examine the drivers behind the establishment mode choice of German multinational enterprises (MNEs) in the sectors of Automotive, Chemicals and Mechanical Engineering in Brazil for the years 1993-2013 using a novel sample of primary data obtained directly from German MNEs. Based on prevalent theories found in the literature, we test the most common hypotheses on our sample. Firms with high R&D activities and firms with prior market knowledge in Brazil in from of previous sales offices are more likely to enter Brazil by a Greenfield investment. We also show that it is the specific private ownership of the German so-called hidden champions that drive those specific SMEs to enter Brazil by Greenfield, a sneaking suspicion that has been made before. Finally, we show that the establishment mode choice between Brazil and the USA only deviates to a low extent, with German MNEs preferring to enter Brazil by Greenfield and the USA by M&A. Thereby, we provide valuable insights for future research in this field.

The role of profits in wage determination: evidence from US manufacturing

We estimate the effect of firms' profitability on wage determination for the American economy. Two standard bargaining models are used to illustrate the problems caused by the endogeneity of profits-per-worker in a real wage equation. The profit-sharing parameter can be identified with instruments which shift demando Using information from the input-output table, we create demand-shift variables for 63 4-digit sectors of the US manufacturing sector. The LV. estimates show that profit-sharing is a relevant and widespread phenomenon. The elasticity of wages with respect to profits-per-worker is seven times as large as OLS estimates here and in previous papers. Sensitivity analysis of the profit-sharing parameter controlling for the extent of unionization and product market concentration reinforces our results.

Activity modeling in practice: a case-based guide to human-centered software engineering

The purpose of this study was to identify whether activity modeling framework supports problem analysis and provides a traceable and tangible connection from the problem identification up to solution modeling. Methodology validation relied on a real problem from a Portuguese teaching syndicate (ASPE), regarding courses development and management. The study was carried out with a perspective to elaborate a complete tutorial of how to apply activity modeling framework to a real world problem. Within each step of activity modeling, we provided a summary elucidation of the relevant elements required to perform it, pointed out some improvements and applied it to ASPE’s real problem. It was found that activity modeling potentiates well structured problem analysis as well as provides a guiding thread between problem and solution modeling. It was concluded that activity-based task modeling is key to shorten the gap between problem and solution. The results revealed that the solution obtained using activity modeling framework solved the core concerns of our customer and allowed them to enhance the quality of their courses development and management. The principal conclusion was that activity modeling is a properly defined methodology that supports software engineers in problem analysis, keeping a traceable guide among problem and solution.

O Modelo de gestão participativa do Plano Nacional do Turismo (PNT-2003/2007): a atuação do CONETUR/RN

To implement policies and plans at the tourist sector involve disposition to the establishment of parceries among government and private initiative, space to the action of studious, researchers and professionals of several areas of knowledge and formation, able of to give new courses no only at the tourism, but to the economy how a every, seen which the tourism had a effect multiplicator, reaching 52 sectors of the economy. At this sense, the Brazil came pruning for a new phase of politic actuation at the touristy activity. Until the year 2002, the tourism politic in the Brazil no had detail, because herself treated of isolated actions and many without continuity. However, at to start 2003, several actions were developed in order to contribute for the national touristy planning. The principal was the creation of Ministério do Turismo, accompanied of the formulation and implementation of the Plano Nacional do Turismo (2003/2007). This work pretend to understand the implementation at the Rio Grande do Norte of the model of participative administration extolled by Plano Nacional do Turismo. The your centre detail the action of the Conselho Estadual de Turismo do Rio Grande do Norte (CONETUR), to promote the participation at the tourism public policies. The bibliographical research contemplated diverse sources in order to compile knowledge of credential authors in the quarrel of inherent subjects to the participation and to the tourism public policies, especially at the Brazil. A qualitative perspective the case study was adapted as research method and for attainment of the data interviews with the members of the Conselho had been carried through beyond consultation the referring documents the dynamics of functioning of the Conselho. The principal actuations of the CONETUR, the directives tourism public policies already made and directed to implementation, the type of participation at made decision, the principal difficulties of the implementation of the participative administration model of the Plano Nacional do Turismo and the degree of participation of the members of the Conselho at the reunions had been identified. The results had shown that exist some difficulties at the implementation of the participation at the Conselho Estadual de Turismo do Rio Grande do Norte, knowledge of the Conselheiros of CONETUR function, the presence of bodies which doesn t directly connected at the touristy activity; the absence of time of the Conselheiros to be presents at reunions; the discontinuity of the presidency of the Conselho; among others. So, the CONETUR show himself how a Conselho with participative characteristics, but with some adapted needs.

Avaliação do extrato do fungo caripia montagnei e de agonistas de PPAR - α no processo inflamatório

The mushrooms have been object of intense research in view of its potential raising of application in different sectors of the pharmacology and alimentary industry. Among diverse bioactive composites of polyssacharides nature that exist in the fungus the glucans are much searched. These are polymers of glucose and classified as the type of glicosidic linking [α, β]. Peroxisome proliferator-activated receptors (PPARs), ranscription factors belonging to the family of nuclear receptors that bind themselves o specific agonists, have shown their importance in controlling the inflammatory process. The aim of this study was to perform a chemical characterization of extract rom the mushroom Caripia montagnei, assess its antiinflammatory and antibacterial effect and determine if this effect occurs via PPAR. This mushroom is composed of carbohydrates (63.3±4.1%), lipids (21.4l±0.9%) and proteins (2.2± 0.3%). The aqueous solution resulting from the fractionation contained carbohydrates (98.7±3.3%) and protein (1.3±0.25%). Analyses of infrared spectrophotometry and of nuclear magnetic esonance demonstrated that the extract of mushroom C. montagnei is rich in β-glucans. In hioglycolate-induced peritonitis, the C. montagnei glucans (50 mg/kg) educed the inflammatory process in 65.5±5.2% and agonists, pharmacological igands, for PPAR: Wy-14643 (49.3±6.1%), PFOA (48.9±3.8%) and clofibrate in 45.2±3.2%. Sodium diclofenac showed a reduction of 81.65±0.6%. In the plantar edema, the glucans from C. montagnei (50 mg/kg) and L-NAME reduced the edema to a similar degree 91.4±0.3% and 92.8±0,5 %, respectively. In all the groups tested, nitric oxide (NO), an inflammation mediator, showed a significant reduction in the nitrate/nitrite levels when compared to the positive control (P<0.001). The C. montagnei glucans did not show cytotoxicity in the concentrations tested (2.5, 5.0, 10.0, 20.0 and 40.0 µg/100 µL). Antibacterial activity demonstrated that, unlike total extract, there was no inhibition of bacterial growth. The C. montagnei glucans show great potential for antiinflammatory applications. This effect suggests that it is mediated by PPAR activation and by COX and iNOS inhibition

Planejamento tributário: Critérios e limites para a desconsideração dos atos e negócios jurídicos pela administração fiscal

Tax planning is a subject that has been increasing in relevance in Tax Law. This current dissertation s objective is to approach the criterion and limits for the disqualification of law acts and business through the Tax Administration. Law acts and business resulted from the conduct of contributors that seek to diminish the growing raise of the tax load, using some means to reduce their burden and increase the possibilities of success in an economical activity, without violating the law in the persecution of paying fewer burdens. On the other hand, the tax administration, through its organs, hoping the increase of burden collection to withstand some determined sectors of the State, with a clear purpose to stop the contributor organizing his activity and structuring it as efficiently as possible, came up with a preliminary draft which left Complementary Law 104, from 10.02.2001, enacted, that inserted the unique paragraph of the National Tax Code, article 116, authorizing the disregard, by the administrative fiscal authority, of Law acts and business practiced to dissimulate the occurrence of burden gain or the nature of obligated incorporating elements, observing the procedures to be established in common law . Our goal is to identify the criteria and limits to disregard law acts and business through the tax administration, pointing out some possible means of action by the tax administration that qualifies it to disregard the contributor s acts and business, just claiming that a saving in the tax costs was made by the contributor s act
