Vertical simulations of ozone were made using a TAPM (The Air Pollution Model) at the Linyuan site in Kaohsiung County, southern Taiwan. Ozone was simulated at altitudes of 0, 100, 300, 500 and 1000 m from November 23 to 25 in 2005 and March 21 to 23 in 2006. The surface ozone concentrations that were predicted using TAPM were high (33.7−119 ppbv) in the daytime (10:00−16:00) and were low (10−40 ppbv) at other times, which predictions were consistent with the observations. The simulated surface ozone concentrations reveal that costal lands typically had higher ozone concentrations than those inland, because most industrial parks are located in or close to the boundaries of Kaohsiung City. Both measurements and simulations indicate that daytime ozone concentrations decreased quickly with increasing height at altitudes below 300 m; while nighttime ozone concentrations were lower at low altitudes (50 to 300 m) than at higher altitudes, partly because of dry deposition and titration of surface ozone by the near-surface nitrogen oxides (NOx) and partly because of the existence of the residual layer above the stable nocturnal boundary layer. The simulations show a good correlation between the maximum daytime surface ozone concentration and average nighttime ozone concentration above the nocturnal boundary layer.

This search was conducted to focus on the relationship between the type of Taiwanese managers¡¦ politics of downward influence and job performance, with responsible individual correlation, and to influence job performance. The search method this study used was group segmentations. After empirical analysis, we found out: 1. By using K-means ¡§Cluster analysis¡¨, we got three different types of Taiwanese manager¡¦s politics of downward influence. We named them by their downward influence politics and strategies as follows: 1-1 Controlling & Counteracting. 1-2 Reciprocal Networking. 1-3 Exerting Pressure. 2. The relationship between individual variable and the type of politics of downward influence are below: 2-1 Manager to the type of politics of downward influence with gender, age and martial status has no significantly effect. 2-2 Manager to the type of politics of downward influence with the education background, working experience and job level has significantly effect. 3. The relationship between the type of Taiwanese managers¡¦ politics of downward influence and job performance are below. 3-1 Manager of the ¡§Reciprocal Networking¡¨ has better contextual performance than ¡§Controlling & Counteracting¡¨. However, manager of the ¡§Exerting Pressure ¡§doesn¡¦t reveal the difference with the contextual performance. 3-2 Manager of the ¡§Exerting Pressure¡¨ has better task performance than ¡§Controlling & Counteracting¡¨. However, manager of the¡¨ Reciprocal Networking¡¨ doesn¡¦t reveal the difference with the task performance. 3-3 Manager of the¡¨ Reciprocal Networking¡¨ has better job performance than the ¡§Controlling & Counteracting¡¨. Manager of the ¡§Exerting Pressure¡¨ has better job performance than ¡§Controlling & Counteracting¡¨.

Abstract Telecom market had been opened since 2001. Facing dramatically changing environment, in order to keep benefiting customers and investors, and to maintain employees¡¦ morale, it is important for the state-owned enterprise to be more competitive. ¡§Human Resource Management¡¨ is the key point to increase its competitive advantages. By understanding employees¡¦ organizational commitment (OC), we can find a way to keep them. Besides, if managers¡¦ politics of downward influence (PDI) can cause employees¡¦ dissatisfaction, employees might have intent to quit (ITQ). It might also increase company¡¦s cost. Therefore, it is necessary to have a research standing from subordinates¡¦ viewpoint, and exploring the effects of managers¡¦ PDI on subordinates¡¦ OC and ITQ. The research collected 629 effective samples from case company in Southern Taiwan via questionnaires and analyzed data by SPSS software. By proving the hypothesis, the research found several results: 1.Through factor analysis, there are three dimensions of power traits: conciliation & reason, authority & exert pressure, hypocrisy & urge by sarcasm. 2.The power trait of ¡§Conciliation & Reason¡¨ has significantly positive influence on OC. 3.The power trait of ¡§Conciliation & Reason¡¨ has significantly negative influence on ITQ. 4.The power traits of ¡§authority & exert pressure¡¨ and ¡§hypocrisy & urge by sarcasm¡¨ have significantly negative influence on OC. 5.The power traits of ¡§authority & exert pressure¡¨ and ¡§hypocrisy & urge by sarcasm¡¨ have significantly positive influence on ITQ.

Kim criticizes non-reductive physicalism as a suitable metaphysics of mind among things because of its failure on the issue of mental causation. The failure is especially present in the thesis of supervenience physicalism. Kim concludes that the causal powers of mental states can be reduced to the causal powers carried by the physical states realizing them. Such causal reduction might involve identity between mental properties and physical properties. I think this is not a necessary conclusion. I try to clarify some premises behind Kim’s analysis, regarding issues of irreducibility, downward causation and the structure of the physical domain. I think the main reason why Kim doubts the plausibility of non-reductive physicalism is his view that downward causation and non-reductive metaphysics indicate the physical domain being hierarchically divided into levels. It seems like Kim would take the opposite position regarding the structure of the physical: an undivided continuum. Yet, the question is if that position follows from the ontological tenet of physicalism. Finally, I conclude that not necessarily, and I develop some further implications and suggestions.

Magister Administrationis - MAdmin / After decades of seeking answers, without much success, to the development challenges facing third world countries, agencies such as the IMF and World Bank have turned increasingly in recent years to issues governance and accountability. In Africa especially, the failure of most development strategies has been attributed to governance issues such as democratic deficits, corruption and lack of political accountability among others. Uganda like several other African countries has been criticised for corruption - a sign that the country has a problem with the functioning of accountability and governance in general. In an attempt to find out whether the local government institutional mechanisms in Uganda embody possible explanations for weaknesses in political accountability, this study hypothesizes that institutional arrangements impact on downward accountability. While concentrating on the anatomy of institutions and the dimensions of accountability to which they relate, as well as on how the formal and informal institutions relate to each other, the study gives an insight into how institutions impact on downward answerability and enforceability at the local level in Uganda. Based on a thorough consideration of both the theoretical and empirical underpinnings of the concept of accountability, the study develops relevance criteria upon which an assessment of both formal and informal institutions' relevance for each of the dimensions of accountability is based. In both cases, formal institutions are found to be more relevant for accountability than informal ones. Critical issues about the capabilities of informal institutions are however raised, culminating in a discussion on the relationship between formal and informal institutions in the study area. While also considering other variables that interact with institutions in affecting accountability, the study calls for a re examination in the concepts under investigation namely 'institutions' and 'accountability'. The study concludes that problems of accountability can be accounted for by weaknesses in institutional design, conceptual weaknesses in the definition of accountability, as well as contextual factors such as resource constraints. In the light of this recognition, the study offers theoretical as well as policy level recommendation

Multiphase flows occurring in pipelines with a serpentine configuration is an important phenomenon, which can be encountered in heat exchangers used in a variety of industrial processes. More specifically, in many industrial units such as a large cracking furnace in a refinery, the tubes are arranged in a serpentine manner and are relatively short. As flow negotiates round the 180o bend at the ends of the tubes, the generated centrifugal force could cause flow maldistribution creating local dry spots, where no steady liquid film is formed on the adjacent straight sections of the pipe. As a result, events including coking, cracking and overheating of heat transfer surfaces may occur and lead to frequent shutdown of the facilities. Consequently, this could increase operating costs and reduce production revenue. Thus, it is desirable to know the effect that the bends exert on the flow in the straight part of the pipe. Apart from this, knowledge of the bend effects on the flows in the pipeline could also be important for the design of other pipelines for gas/liquid transport, e.g. offshore gas and oil pipelines. Quite a large number of studies have been found in the literature. The majority of them were for two-phase flow with small diameter pipes (i.d. ≤ 50 mm). However, studies with large diameter pipes (i.d. ≥ 100 mm), have increasingly been considered in recent years as problems related to large diameter vertical pipes are being encountered more and more often in industrial situations. This thesis studies the effect of 180o bends on the characteristics and development of gas-liquid two-phase flows in large diameter downward and upward pipes. The study particularly focuses on the influence of serpentine configuration on flow structure, cross-sectional void distribution and circumferential liquid film profiles and their development along the downward and upward sections. It was found that both the top and bottom bends have considerable impacts on flow behaviour, although to varying degrees. These impacts were highly dependent on the air and water flow rates. For sufficient flow rates, the bends were observed to create flow maldistribution in the adjacent straight section, due to the effects of centrifugal force. The air moved towards the inner zone of the bend and the water towards the outer zone, while a lesser quantity of water was identified on the other surfaces of the pipe. Investigation of the film thickness development in the downward and upward sections showed that, the liquid film behaviour close to the bends was significantly different from those located further away. This can be attributed to the centrifugal force of the bends. Examination of the power spectral density (PSD) along the downward and upward sections showed that, the shape of PSD located in the adjacent section to the bends, was substantially different from those located further away. Furthermore, several flow regime maps were generated which showed that, in addition to bubbly, intermittent and annular flows, unstable flows existed along the upward section, particularly for low gas and water flow rates. In this study it was found that, the lower bend was periodically blocked by the liquid and then blown through by the accumulated air. The data obtained from this study were compared with different theoretical correlations found in the existing literature. Some discrepancy between the results of the current study and those of previous published materials was noted. Updated correlations were presented which provided well results when they applied for the data obtained from the current study and previous studies.

O regime de meta para a inflação foi adotado por um amplo conjunto de países nos últimos anos. Evidentemente, a definição da meta de inflação a ser perseguida é parte essencial do regime. O presente trabalho pretende contribuir para o debate sobre a meta ótima para o Brasil. O trabalho está dividido em três ensaios que, por caminhos diversos, buscam estimar quantitativamente os custos e benefícios de diferentes metas de inflação para a economia brasileira. O foco é sobre os efeitos de longo prazo de diferentes metas, uma vez que esses são mais relevantes do que os possíveis custos de ajustamento para uma eventual nova meta de inflação. O primeiro artigo aborda a questão sobre a meta de inflação ótima para o Brasil por meio da perda de bem estar medida pela demanda de moeda, um canal clássico considerado pela literatura. O segundo avalia a relação entre o nível e a incerteza sobre a inflação futura, utilizando para tanto modelos para a estimação da variância condicional da inflação, as expectativas de inflação relatadas por analistas econômicos e medidas de inflação implícita em preços de ativos. O terceiro artigo apresenta um enfoque mais teórico e estrutural, apresentando um modelo no qual existe um trade-off para a meta de inflação e calibrando esse modelo para obter estimativas da meta ótima para a economia brasileira. O modelo considera, de um lado, a perda de bem estar causada pela inflação através da demanda de moeda e, de outro, o benefício pela redução da perda de eficiência econômica ocasionada pela rigidez dos salários nominais. Concluímos que a análise exposta no presente trabalho sugere que, tendo em vista a redução da incerteza macroeconômica na economia brasileira nos últimos anos, haveria motivos também para uma redução gradual da meta de inflação. Contudo, também aponta que não se deve buscar metas muito baixas, uma vez que o benefício adicional em se reduzir a meta de inflação é relativamente pequeno quando já se está em um nível de inflação baixo. / Inflation targeting regimes have been adopted by a large number of countries in recent years. Obviously, the definition of the actual inflation target to be pursued is an essential part of this regime. This work aims to make a contribution to the debate about the optimal target for Brazil. The three essays follow different paths in an attempt to estimate the quantitative costs and benefits of the different inflation targets for the Brazilian economy. The focus is on the long-term effects of the different targets as these are more important than the possible costs during the transition towards the new inflation target. The first article discusses the optimal inflation target based on the welfare loss measured by the money demand function, a classic channel highlighted in the literature. The second assesses the relation between the level and uncertainty of future inflation. We investigate this issue with the use of econometric models to estimate the conditional variance of inflation, of inflation expectations reported by professional economic analysts and of break-even inflation rates. The third article presents a more theoretical and structural focus. We present a model in which there is a trade-off for the inflation target and this model is calibrated to obtain estimates of the optimal target for the Brazilian economy. On one hand, the model considers the welfare loss caused by inflation through money demand and, on the other, the benefit from the reduced frequency of periods in which a downward nominal wage restriction binds. Our conclusion is that the analysis presented suggests that, considering the lower macroeconomic uncertainty observed in Brazil in the recent years, there would be reasons for a gradual reduction in the inflation target. However, it also suggests that very low targets should not be set as the additional benefit in reducing the inflation target is relatively small once the inflation target has already been set at a low level.

O objetivo deste trabalho consiste em analisar as implicações das regras sociais implícitas brasileiras no desenvolvimento sócio-econômico do país sob a luz da teoria neoinstitucionalista. Inserido neste arcabouço teórico tem-se um desenvolvimento alcançado a partir de um progressivo ajustamento entre as instituições e a realidade. Como realidade, entende-se, neste estudo, o capitalismo. Desta forma, primeiramente, se analisa as instituições que propiciaram o surgimento do capitalismo na Europa, enfatizando as revoluções precedentes que influenciaram a formação sócio-cultural deste sistema. Posteriormente, se realiza um resgate histórico da formação sócio-econômica do Brasil destacando os aspectos culturais enraizados na sociedade durante o período colonial. Observa-se que, a despeito da industrialização, o Brasil permaneceu calcado em valores tradicionais e arcaicos que não condizem com os valores modernos da gênese do capitalismo. Tendo em vista estes conceitos, utiliza-se do Reconstitutive Downward Causation para se analisar a forma em que emergem as instituições no Brasil. Observou-se que, enquanto as instituições que operam no ambiente informal surgem a partir dos hábitos mentais dos próprios indivíduos, as instituições que operam no âmbito formal são decorrentes da importação de modelos externos. Esta incoerência faz com que surja o ‘jeitinho brasileiro’, uma instituição que permite ao indivíduo lidar com a esfera formal mantendo seus hábitos mentais. / The objective of this study consists of analyzing the implications of the Brazilian implicit social rules in the socio-economic development of the country under the light of neoinstitutionalist theory. Inserted in this theoretical approach, development it is achieved from a gradual adjustment between institutions and reality. As, reality, it is understood in this study, capitalism. Thus, first, examines the institutions that enabled the emergence of capitalism in Europe, emphasizing the previous revolutions that have influenced the social-cultural formation of the system. Subsequently, it is done a rescue of the historic socio-economic formation of Brazil highlighting the cultural aspects rooted in society during the colonial period. It is observed that, in spite of industrializations, Brazil remained based on traditional and archaic values which do not match with the values of the genesis of modern capitalism. In view of these concepts, the Reconstitutive Downward Causation concept it is used to examine the way in which institutions emerge in Brazil. It was observed that while the institutions operating in the informal environment arise from the mental habits of the individual themselves, the institutions that operate under formal scope are resulted from the importation of foreign models. This inconsistency makes it arises the ‘jeitinho brasileiro’, an institution that allows the individual to deal with formal sphere keeping its mental habits.

Manager¡¦s managerial effectiveness is measured by how successfully he/she influences others. Leaders exert influence tactics to achieve task objective and organizational long-term objectives in a complex environment in order to maximize their job performance. By means of influence tactics, managers exert political behavior over others to achieve their organizational power settings. Thus, the purpose of the study is to understand the relationship between downward influence tactics and job performance. Results showed as following: 1. Male managers use more rationality influence tactic than that of females; female manager¡¦s contextual performance is better than that of males. 2. Managers with age between 30-39 use rationality influence tactic more than those of age 50 and above; managers with age below 30 use network and counteract influence tactics more than those of other age groups; task performance and contextual performance of managers with age over 50 are better than other age groups 3. Single managers use counteract influence tactic more than married managers; task performance and contextual performance of single managers are better than those of married managers 4. Managers with Master/Doctoral degrees use rationality, network, exchange, pressure, and counteract influence tactics more than those of other educational backgrounds. 5. Managers with 1 ~ 3 years working experiences use rationality and counteract influence tactics more than those of other years of working experiences; managers with working experiences over 10 years use network and pressure more than those of other years of working experiences. 6. High-level managers use rationality and pressure influence tactics more than those of other lower level managers; project-based managers use network and counteract influence tactics more than those of other levels of managers. 7. Middle-level managers have higher task performance than that of other levels of managers; high-level managers have higher contextual performance than that of other levels of managers. 8. After using gender, age, martial status, educational background, working experience and job level as control variables, and compare the relationship between downward influence tactics and job performance, we found: 8.1 Managers who are male, age over 35, single, college and below educational background, middle/high level, 5 years and above working experiences, the more rationality influence tactic they use, the better their job performance are. 8.2 Managers who are university and above, have 5 years and above working experiences, the more exchange influence tactic they use, the better their job performance are. 8.3 Managers who have less than 5 years of working experiences, the more pressure influence tactic they use, the better their task performance are. 8.4 Managers who are male, 35 years and above, single, university and below, and middle/high level, the more exchange influence tactic they use, the better their contextual performance they are.

We have from our research, conducted in Guardamar del Segura, Spain, discovered that most of the communication between native Spaniards and immigrant Bulgarians is negative non-verbal communication which leads to a division between the two groups. The result of high unemployment and social stress, which the current situation in Spain provides, tend to create stronger ties inside the groups and at the same time enlarge the distance towards other groups. Also, the large amount of nonverbal communication such as observing each other’s behavior leads in this case to negative stereotyping and prejudices that creates and maintain the different group’s relations in the society.
