Transfer price is an important field of study for profit maximization. As more multinational enterprises (MNEs) are involved in global trading in the recent decades, the objective to set an optimized transfer price is more crucial than ever since the difference in tax rates and tariffs have sophisticated impacts on the overall profit for the corporation. In this thesis, which focuses primarily on Asia Pacific, I will review historical transfer pricing methods, explore the factors that affect transfer price determination, and construct a mathematical model to determine the optimal transfer price by comparing and contrasting the different transfer pricing methods with data from a hypothetical company. Particularly, I will illustrate the effects of taxes and tariffs on the determination of transfer price. Consequently, I will perform sensitivity analysis with respects to tariffs, taxes, and shipping costs. The thesis will conclude with recommendations on the optimized transfer pricing methods and insights on the implications for the method.

Kunuji, Oluwole Anthony. "Towards a symbio-democratic federal framework : division of powers and fiscal resources in Nigeria." Thesis, University of Warwick, 2018. http://wrap.warwick.ac.uk/104209/.
Full textAbstract:
Nigeria’s federal system of government is grossly problematic. It is characterized by an inordinate concentration of powers and fiscal resources in the central government. Not only is this centralist division of powers antithetical to the idea of federalism, it also fosters the dictatorship of the central government vis a vis the other levels of government. Furthermore, it indirectly entrenches the domination of the minority ethnic groups by the larger ones. So centralized is Nigeria’s ‘federal’ arrangement that it is, perhaps, better described as a unitary contraption designed to perpetually establish the hegemony of the central government. As we shall later see in this thesis, the existing division of powers among the levels of government in Nigeria has been the source of protracted acrimony, conflict, and rancour threatening to tear the federation apart. Through theoretical analysis, this thesis examines the suitability of the existing power allocation structure for a country like Nigeria. The thesis argues that the ethnically diverse character of the Nigerian federation and the age-long clamour for autonomy by the constituent units of the federation make the existing division of powers absolutely untenable and unsuitable for Nigeria. This thesis thus proposes a complete abrogation of the existing constitutional framework for the division of powers among the levels of government in Nigeria, and its replacement with a restructured federal framework that is popularly designed by the Nigerian people and cognizant of the country’s diversity. Further to this, the thesis advocates a division of powers that entrenches state and local government autonomy without compromising the unity of the Nigerian federation. It is argued that only a framework such as this will conduce to the federation’s peace and stability, and help to stem the secessionist tide currently rocking the country.

As medical device manufacturers operating in the Asia-Pacific region are planning for increased demand in the near future, they must evaluate their manufacturing footprint strategies to determine if they are getting the most value out of their supply chains given the various incentives and costs associated with regional manufacturing. Company X is investigating manufacturing expansion opportunities for medical devices due to the significant revenue growth rates expected for the Asia-Pacific region, especially in the emerging markets. This thesis deals with the development of a repeatable methodology that can be used to evaluate various medical device products and manufacturing capabilities for Asia-Pacific sourcing. The methodology was tested on a selected subsidiary to determine if a regional manufacturing opportunity exists. Furthermore, a business process, which includes insights into data collection, team formation, and implementation of footprint decisions, was developed for Company X to use in determining its overall network strategy for the sector. Other manufacturers can apply the methodology and the business process in the development of their manufacturing footprint strategies as well. Although the results from the decision analysis did not favor expansion of the manufacturing operations for the selected Product Line B in the Asia-Pacific region, they helped in identifying the key factors that would favor regional expansion. In addition, crucial factors that may be difficult to quantify, such as intellectual property rights, must be considered before making a expansion decision, even if it is the favored outcome based on the results of the decision analysis for other product lines or subsidiaries.

Hegi, Benjamin P. "Extermination Warfare? The Conduct of the Second Marine Division at Saipan." Thesis, University of North Texas, 2008. https://digital.library.unt.edu/ark:/67531/metadc6098/.
Full textAbstract:
Historians John W. Dower, Craig Cameron, and Ronald Takaki argue that the Pacific War was a war of extermination fueled by race hate. Therefore, the clash between the military forces of the Japanese Empire and United States of America yielded a "kill or be killed" environment across the battlefields of the Pacific. This work examines the conduct of the Second Marine Division during its campaign of conquest against the Japanese held island of Saipan from June 15, 1944-July 9, 1944. It is based upon traditional military history sources to test their theories in context of the conduct of Marines toward Japanese soldiers and civilians during the Saipan campaign. Did Marines practice a war of extermination or conduct themselves in a humane manner?

Velásquez, Sandoval Francisco. "Propuesta de un sistema de control de gestión para División Banca Personas, Banco Security." Tesis, Universidad de Chile, 2017. http://repositorio.uchile.cl/handle/2250/144373.
Full textAbstract:
TESIS PARA OPTAR AL GRADO DE MAGÍSTER EN CONTROL DE GESTIÓNEl presente proyecto de grado fue desarrollado sobre la Unidad Estratégica de Negocios Gerencia División Banca Personas de “Banco Security”, que corresponde a una de las 4 divisiones especializadas de crédito que actualmente posee el banco, orientada al desarrollo de la banca de ingresos altos, cuenta con más de 55.000 clientes, 28 sucursales a lo largo del país, con una participación de un 3% en colocaciones en el mercado bancario/financiero. El presente estudio tiene por propósito dar respuesta a dicho desafío aplicando un modelo de control de gestión derivado del sistema integral de gestión de circuito cerrado de seis etapas propuesto por (Kaplan y Norton en su libro “The Executión Premium” 2012) El modelo aplicado en este estudio consta de tres fases: formulación estratégica, desarrollo de la estrategia y alineamiento organizacional; En la formulación estratégica se establecen el propósito, objetivos de largo plazo y límites valóricos de la Gerencia División Banca Personas través de la definición de la misión, visión y creencias, respectivamente. Dichas declaraciones estratégicas apuntan esencialmente al rol social que cumple la unidad al ser un socio de los clientes. El análisis estratégico efectuado permitió identificar las capacidades y recursos con que cuenta la unidad estratégica de negocios para generar ventajas competitivas y enfrentar las complejidades del entorno que podrían afectar el cumplimiento de su misión y visión. Posteriormente se define la propuesta de valor ofrecida a sus clientes, sus atributos (soluciones oportunas e integrales y servicio de atención de excelencia) y se relaciona su cumplimiento con los resultados del análisis FODA. Se concluye que tanto las creencias como los recursos y capacidades de la unidad impulsan el cumplimiento de los atributos de su propuesta de valor. La formulación estratégica concluye con la definición de la propuesta de valor, la que relaciona los atributos y el análisis FODA. En la segunda fase de desarrollo de la estrategia, mediante el modelo CANVAS se modela la lógica cómo la Gerencia División Banca Personas opera y crea valor para la sociedad y articula su propuesta de valor. El análisis de rentabilidad del modelo permite identificar tres estrategias que actualmente utiliza la unidad: segmento por perfil del cliente, de excelencia operacional y de alianzas, y las vincula con el cumplimiento de los atributos de la propuesta de valor. Al analizar el modelo en búsqueda de alcanzar un mayor nivel de rentabilidad (cumplimiento de los atributos de la propuesta de valor al menor costo posible), se identifican propuestas de mejora en las estrategias de: Segmento: segmentar a los clientes, para impulsar el cumplimiento del atributo integral y oportuno. Excelencia operacional: introducir cambios en los procesos, mejorar la infraestructura y sistemas de información para impulsar el cumplimiento del atributo soluciones oportunas. Alianzas: generar alianzas con proveedores y otros grupos de interés para impulsar el cumplimiento de los tres atributos: soluciones oportunas e integrales y servicio de atención de excelencia. Una vez definido el modelo de negocios y la estrategia se genera el mapa estratégico. Éste muestra cuáles son los activos intangibles con que debe contar la unidad y cómo los procesos relevantes de la Gerencia División Banca Personas aportan al cumplimiento de los atributos de su propuesta de valor e impulsan el cumplimiento de su misión. Luego se elabora el cuadro de mando integral que asigna indicadores y metas a los objetivos definidos en el mapa, con el propósito de evaluar el éxito de la estrategia y de generar iniciativas que impulsen el cumplimiento de los objetivos. La tercera fase y final del estudio corresponde al alineamiento organizacional. Esta etapa comienza con la elaboración de los tableros de control del departamento de operaciones y del departamento de desarrollo comercial, ambos dependientes de la Gerencia División Banca Personas. Dichos tableros surgen a partir del desdoblamiento estratégico y apuntan a generar objetivos y estrategias específicas para cada departamento, que se traducen en indicadores y metas propias, alineadas con los objetivos y estrategia de la Gerencia División Banca Personas. Esta fase concluye con el análisis del actual modelo de incentivos de la Gerencia División Banca Personas y se efectúa una propuesta de mejora de dicho modelo, sobre la base de sus tableros de control. Con ello se persigue que los integrantes de ambas unidades se sientan motivados y dirijan sus esfuerzos al cumplimiento de los objetivos estratégicos de más alto nivel.

Full textAbstract:
A four-year war in Croatia in the early nineties left Eastern Slavonia and the Vukovar region struggling with the consequences of inter-ethnic conflict and human suffering. Poorly addressed post-ethnic reconciliation issues resulted in many challenges in everyday living for the people of Vukovar, especially so with the segregation of the public educational system based on language and ethnicity. This research explored the outcomes of the policy in Vukovar to divide the student body based on the language they spoke.
The literature review examined issues of inter-ethnic conflict, post-war reconciliation, and the process of grieving and transition in order to define how these processes affect people involved in public schooling in Vukovar today. I have examined literature in intercultural sensitivity, intercultural conflict, reconciliation, cultural marginality, and identity formation.
I compiled data through in-depth interviews with five specialists in the field of public educational system in Vukovar. They included a journalist and author, a teacher, administrators, and parents.
I found the presence of slow but consistent increase in readiness for the process of rejoining schools in Vukovar. This convergence in attitudes of the majority and the minority groups regarding their public school education might be the best indicator that Vukovar is shifting from the position of grieving to a place more open to the new solutions and agreements. However, one should not forget that bringing students together is not a key to reconciliation. Even though it appears that parents and teachers have motivation and good incentives to accomplish the process of reuniting, the students themselves lack the understanding of the importance of the same.
I hope that this study will provide insight into the state of affairs in Vukovar's educational system today and may provide insight into the ways of managing the larger issues of reintegration and reconciliation between the diverse cultural communities.

(cont.) counterpart. Among intra-cell orthogonal schemes, we show that the most efficient broadcast signal is a linear superposition of many binary orthogonal waveforms. The information set is also binary. Each orthogonal waveform is generated by modulating a periodic stream of finite-length chip pulses with a receiver-specific signature code that is derived from a special class of binary antipodal, superimposed recursive orthogonal code sequences. With the imposition of practical pulse shapes for carrier modulation, we show that multi-carrier format using cosine functions has higher bandwidth efficiency than the single-carrier format, even in an ideal Gaussian channel model. Each pulse is shaped via a prototype baseband filter such that when the demodulated signal is detected through a baseband matched filter, the resulting output samples satisfy the Generalized Nyquist criterion. Specifically, we propose finite-length, time overlapping orthogonal pulse shapes that are g-Nyquist. They are derived from extended and modulated lapped transforms by proving the equivalence between Perfect Reconstruction and Generalized Nyquist criteria. Using binary data modulation format, we measure and analyze the accuracy of various Gaussian approximation methods for spread-spectrum modulated (SSM) signalling ...
We study forward link performance of a multi-user cellular wireless network. In our proposed cellular broadcast model, the receiver population is partitioned into smaller mutually exclusive subsets called cells. In each cell an autonomous transmitter with average transmit power constraint communicates to all receivers in its cell by broadcasting. The broadcast signal is a multiplex of independent information from many remotely located sources. Each receiver extracts its desired information from the composite signal, which consists of a distorted version of the desired signal, interference from neighboring cells and additive white Gaussian noise. Waveform distortion is caused by time and frequency selective linear time-variant channel that exists between every transmitter-receiver pair. Under such system and design constraints, and a fixed bandwidth for the entire network, we show that the most efficient resource allocation policy for each transmitter based on information theoretic measures such as channel capacity, simultaneously achievable rate regions and sum-rate is superposition coding with successive interference cancellation. The optimal policy dominates over its sub-optimal alternatives at the boundaries of the capacity region. By taking into account practical constraints such as finite constellation sets, frequency translation via carrier modulation, pulse shaping and real-time signal processing and decoding of finite-length waveforms and fairness in rate distribution, we argue that sub-optimal orthogonal policies are preferred. For intra-cell multiplexing, all orthogonal schemes based on frequency, time and code division are equivalent. For inter-cell multiplexing, non-orthogonal code-division has a larger capacity than its orthogonal

Full textAbstract:
La thèse a pour objet de caractériser les concepts de division technique et cognitive du travail et vise également à mettre en évidence la montée de la dimension cognitive du travail dans les activités situées au cœur du processus de création de valeur, notamment dans l’industrie manufacturière postfordiste. Elle met l’accent sur les transformations historiques de la division technique du travail, qui ont caractérisé l’évolution du capitalisme industriel et sur la position relativement hégémonique de ses principes dans l’organisation de l’industrie manufacturière durant la période des Trente Glorieuses. Puis, elle insiste sur l’émergence d’un nouveau modèle d’organisation du travail qui a caractérisé le capitalisme contemporain durant la période postfordiste. Ainsi, avec l’avènement du capitalisme cognitif, l’accent est mis sur la montée en puissance des principes de la division cognitive du travail, dans l’organisation de l’industrie manufacturière postfordiste et cela au détriment des principes de la division technique du travail, qui perdent leur position dans l’organisation du travail. Des faits stylisés ont été mobilisé pour justifier cette tendance au développement des principes de la division cognitive du travail, dans l’industrie manufacturière postfordisteThis thesis has for object to characterize the concepts of technical and cognitive division of the work and also aims at highlighting the rise of the cognitive dimension of the work in the activities situated at the heart of the process of value creation, in particular in the postfordiste manufacturing industry. She emphasizes the historic transformations of the technical division of the work, which characterized the evolution of the industrial capitalism on the relatively hegemonic position of its principles in the organization of the manufacturing industry during the period Thirty Glorious. Then, she insists on the emergence of a new model of organization of the work which characterized the contemporary capitalism during period postfordiste. So, with the succession of the cognitive capitalism, the accent is put on the increase in importance of the principles of the cognitive division of the work, in the organization of the manufacturing industry postfordiste and in to the detriment of the principles of the technical division of the work, which lose their position in the organization of the work. Stylized fact was mobilized for justifying this trend to the development of the principles of the cognitive division of the work, in the postfordiste manufacturing industry

Full textAbstract:
Följande studie tar upp problematiken bakom skador inom division II och III ishockey. Antalet skador inom denna sport är många och ur ett samhällsperspektiv blir det därför viktigt att undersöka vad som krävs för en förändring. Ishockey är en sport som går snabbt samt använder sig av kroppskontakt i form av tacklingar. Detta gör att flera skador uppdagas inom sporten där skador rörande axeln är en stor del. Denna studie syftar genom detta till att uppdaga om någon förebyggande träning sker gällande axelskador inom division II eller III. Vidare undersöks vad som krävs för att möjliggöra att förebyggande träning sker i större omfattning. Fem tränare medverkade i studien vilka alla hade minst ett års erfarenhet av division II eller III ishockey. Teorin rörande organisationskultur berördes för att kunna belysa kulturens inverkan på sporten ishockey. Kulturen ansågs här viktig då den bidrar till ökad förståelse till varför sporten fungerar som den gör samt varför ett visst beteende utförs. Den insamlade empirin i studien analyseras med hjälp av en direkt tematisk innehållsanalys. Denna analys kan uppdaga teman och kategorier med målet att ge svar på de frågeställningar som används.The following study examines the problems regarding injuries in division II or III ice-hockey. The amount of injuries in this sport is high and when considering the effect on society something needs to be done in order to change it. Ice-hockey is a fast sport with body-checking being allowed. This leads to a number of injuries with shoulder injuries being one of the most common. The aim of this study was to examine if any preventive training is being used regarding shoulder injuries in division II or III. The study also examines which possibilities could be used in order to enable a larger amount of preventive training. Five trainers were interviewed, and all of these trainers had at least one year of experience being a trainer in division II or III. The theory considering organizational culture was used in order to better understand how the culture affects the game of ice-hockey. The culture was here considered important due to the fact that it affects how the sports works and why a certain behavior is used. The gathered information in this study was analyzed through a direct thematic analysis. With this, themes and categories could be developed with the aim of answering the questions asked in this study.

Full textAbstract:
Since the 1980s the locus of manufacturing and some services have moved to countries of the Global South. Liberalization of trade and investment has added two billion people to world labour supply and brought workers everywhere into intense competition with each other. Under orthodox neoliberal and neoclassical approaches free trade and open investment should benefit all countries and lead to convergence. However considerable differences in wages and working hours exist between workers of the Global North and those of the Global South. The organising question for the thesis is why workers in different countries but the same industries get different wages. Empirical evidence reviewed in the thesis shows that productivity does not explain these wage differences and that workers in some parts of the South are more productive than workers in the North. Part of the thesis examines the usefulness of explanations drawn from Marxist, institutionalist and global commodity chain approaches. There is a long established argument in Marxist and neo-Marxist writings that differences between North and South result from imperialism and the exercise of power. This is the starting point to review ways of understanding divisions between workers as the outcome of a global class structure. In turn, a fault line is postulated between productive and unproductive labour that largely replicates the division between the Global North and the Global South. Workers and their organizations need shared actions if they are to resist global competition and wage disparities. Solidarity has been the clarion of progressive movements from the Internationals of the early C19th through to the current Global Unions and International Confederation of Trade Unions (ICTU). The thesis examines how nationalism and particular interests have undermined solidarity and reviews the major implications for current efforts to establish and advance a global labour position.

Full textAbstract:
The European Union (EU) has comparative advantage in regional integration. Moreover, regionalism is a growing phenomenon, as both the growing number of regional trade agreements and literature on new regionalism indicate. In this context, the EU has incorporated regional integration into European development policy as a strategy to help integrate the African, Caribbean and Pacific (ACP) states into the global economy, with the negotiation of region-to-region reciprocal free trade agreements, called Economic Partnership Agreements (EPA). This thesis examines the extent to which the Pacific may constitute a region, for the purposes of the Cotonou Agreement, along cultural, political and economic dimensions of regional cooperation. This is in order to measure the potential for regional integration in the Pacific, as well as to test the applicability of the EU's regional template of development in this context. A theoretical framework is developed, based on the political economy of regional cooperation among developing states, in order to apply a series of propositions to the test the integrative potential of the Pacific region. The key finding is that regionalism in the Pacific is easily politicised. Anthropological evidence and economic analysis also confirm the informal nature of regional cooperation in the Pacific works against global imperatives for deeper regional integration, as Pacific islanders have generally not subscribed to a common identity, and the welfare benefits from regional free trade are shown to be minimal. Consequently, the Pacific accepts the EPA platform in order to maintain the development partnership with the EU, rather than because regional free trade is the most desired vehicle for development in the region. A trade agreement will therefore be concluded with the Pacific ACP states, but its form and timing remain the key issues for clarification.

Full textAbstract:
With high date rates using Enhanced Uplink (EUL), a conventional signal to interference ratio (SIR) based power control algorithm may lead to a power rush due to self interference or incompatible SIR target [2]. Time division (TD) scheduling in Wideband Code Division Multiplex Access (WCDMA) is considered to be a key feature in achieving high user data rates. Unfortunately, power oscillation/peak is observed in time division multiplexing (TDM) at the transition between active and inactive transmission time intervals [1]. Therefore there is a need to revisit power control algorithms for different time division scheduling scenarios. The objective of power control in the context of this study is to minimize the required rise over thermal noise (RoT) for a given data rate, subject to the constraint that the physical layer control channel quality is sufficient (assuming that the dedicated physical control channel (DPCCH) SIR should not go below 3dB with a probability of at most 5%). Another goal is to minimize the local oscillation in power (power peaks) that may occur, for example due to transitions between active and inactive transmission time intervals. The considered hybrid power control schemes are: (1) non-parametric Generalized rake receiver SIR (GSIR) Inner Loop Power Control (ILPC) during active transmission time intervals + Received Signal Code Power (RSCP) ILPC during inactive transmission time intervals and (2) RSCP ILPC during active transmission time intervals + GSIR ILPC during inactive transmission time intervals. Both schemes are compared with pure GSIR and pure RSCP ILPC. Link level simulations with multiple users connected to a single cell show that: The power peak problem is obviously observed in GSIR + GSIR transmit power control (TPC), but in general it performs well in all time division scenarios studied. GSIR outperforms other TPC methods in terms of RoT, especially in the TU channel model. This is because it is good in combating instantaneously changed fading and accurately estimates SIR. Among all TPC methods presented, GSIR + GSIR TPC is best in maintaining the quality of the DPCCH channel. No power rush is observed when using GSIR + GSIR TPC. RSCP + RSCP eliminates the power peak problem and outperforms other TPC methods presented under the 3GPP Pedestrial A (pedA) 3km/h channel in terms of RoT. However, in general it is worse in maintaining the control channel’s quality than GSIR + GSIR TPC. GSIR + RSCP ILPC eliminates the power peak problem and out-performs GSIR power control in the scenario of 2 and 4 TDM high data rate (HDR) UE and 2 TDM HDR UE coexistence with 4 Code DivisionMultiplex (CDM) LDR UE, in the pedA 3km/h channel, in terms of RoT. However, the control channel quality is not maintained as well during inactive transmission time intervals. It is not recommended to use RSCP + GSIR TPC since it performs worst among these TPC methods for most of the cases in terms of RoT, even though it is the second best in maintaining the control channel quality. The power peak is visible when using RSCP + GSIR TPC. To maintain the control channel’s quality, a minimum SIR condition is always used on top of all proposed TPC methods. However, when there are several connected TDM HDR UEs in the cell, results indicates that it is challenging to meet the quality requirement on the control channels. So it may become necessary to limit the number of connected terminals in a cell in a time division scenario.Med den höga datahastighet som Enhanced Uplink (EUL) medger kan en konventionell algoritm för effektkontroll baserad på signal to interference ratio (SIR) leda till effekthöjning beroende på självinterferens eller felaktigt SIR mål. Time division (TD) schedulering vid Wideband Code Division Multiple Access (WCDMA) anses vara en nyckelfunktion för att uppnå höga datahastigheter. I övergången mellan aktiv och inaktiv transmissionstidsintervall vid time division multiplexing (TDM) har effektoscillering/effektpeak observerats. Detta gör det nödvändigt att se över algoritmerna för effektkontroll vid olika scenarion av TD schedulering. Målet med effektkontrollen i denna studie är att minimera rise over thermal noise (RoT) för en given datahastighet givet begränsningen att kvaliteten på physical layer control channel är tillräcklig (beaktande att dedicated physical control channel (DPCCH) SIR inte understiger 3dB med en sannolikhet på som mest 5%). Ett annat mål är att minimera den lokala effektoscillationen (effektpeakar) som kan inträffa till exempel vid övergång mellan aktiv och inaktiv transmissionstidsintervall. De undersökta hybrida metoderna för effektkontroll är: (1) icke-parametrisk Generalized rake receiver SIR (GSIR) Inner Loop Power Control (ILPC) vid aktiv transmissionstidsintervall + Received Signal Code Power (RSCP) ILPC vid inaktiv transmissionstidsintervall och (2) RSCP ILPC under aktiv transmissionstidsintervall + GSIR ILPC under inaktiv transmissiontidsintervall. Båda metoderna jämförs med ren GSIR och ren RSCP ILPC. Länk nivå simulering med flera användare anslutna till en enda cell visar att: Problemet med effektpeakar observeras tydligt vid GSIR + GSIR transmit power control (TPC) men generellt sett presterar den bra i alla studerade TD scenarion. GSIR presterar bättre än andra TPC metoder beträffande RoT, speciellt i TU kanal modellen. Detta beror på att metoden är bra på att motverka momentant förändrad fading och med god precision estimerar SIR. Bland alla presenterade TPC metoder är GSIR + GSIR TPC den bästa på att behålla en god kvalitet på DPCCH kanalen. Ingen effekthöjning har observerats vid GSIR + GSIR TPC. RSCP + RSCP eliminerar problemet med effektpeakar och presterar bättre än andra TPC metoder presenterade under 3GPPs Pedestrial A (pedA) 3km/h kanal beträffande RoT. Dock är metoden generellt sett sämre på att behålla kontrollkanalens kvalitet än GSIR + GSIR TPC. GSIR + GSIR ILPC eliminerar problemet med effektpeakar och presterar bättre än GSIR power control i ett scenario med 2 och 4 TDM high data rate (HDR) UE och 2 TDM HDR UE tillsammans med 4 Code Division Multiplex (CDM) LDR UE i pedA 3km/h kanalen beträffande RoT. Dock kan inte kvaliteten på kontrollkanalen behållas i detta fall heller under inaktiv transmissionstidsintervall. Det är inte rekommenderat att använda RSCP + GSIR TPC eftersom den presterar sämst av alla TPC metoder beträffande RoT i de allra flesta fall. Till dess fördel är att den är den näst bästa på att behålla kvaliteten på kontrollkanalen. Effektpeakar har observerats när RSCP + GSIR TPC använts. För att behålla kontrollkanalens kvalitet används alltid en minimum SIR nivå ovanpå alla föreslagna TPC metoder. När det finns flera anslutna TDM HDR UEs i cellen indikerar resultaten att det är en utmaning att behålla kvalitetskraven på kontrollkanalen. På grund av detta kan det bli nödvändigt att begränsa antalet anslutna terminaler i en cell i ett TD scenario.

The four essential cell division genes ftsQ, ftsA, ftsZ, and envA are arranged sequentially within a large cluster of genes required for cell envelope growth and form. The bacteriophage λJFL100 carries the 1.8 kilobase EcoR1-HindIII chromosomal restriction fragment which spans the ftsQ and part of ftsA coding sequences. This fragment contains at least two promoters; one within ftsQ is required for the expression of ftsA and one within ftsA is required for expression of ftsZ. The fts fragment is cloned upstream of a lacZ gene so that transcription originating from within the fragment leads to the production of β-galactosidase. Expression from the fts promoters in cells lysogenic for the phage is shown to be derepressed in the absence of FtsA protein. The results presented here suggest that transcription from these promoters is linked to the cell's periodic requirement for FtsA protein during septum formation. The exact positions of the promoters within the group are not yet known although their approximate locations have been determined by promoter assay and sequence analysis. An attempt has been made to define the position of the ftsA promoter more precisely by in-vitro transcription from short, defined templates and by the sequential deletion of ftsQ. Serial deletion through ftsQ has revealed what appears to be a complex upstream regulatory region, reminiscent of a eukaryotic enhancer element, which influences the expression of ftsA. A model is presented for the transcriptional control of ftsA expression.

Full textAbstract:
Animal cells undergo a dramatic series of cell shape changes as they pass through mitosis and divide which depend both on remodelling of the contrac- tile actomyosin cortex and on the release of cell-substrate adhesions. Here, I use the adherent, non-transformed, human RPE1 cell line as a model system in which to explore the dynamics of these shape changes, and the function of mitotic adhesion remodelling. Although these cells are highly motile, and therefore polarised in interphase, many pause migration and elongate to be- come bipolar prior to mitosis. Interestingly, and in contrast to most reported cell types, these cells do not round fully, and many leave long adhesive tails con- nected to the underlying substrate. These are typically bipolar, persist through- out mitosis, and guide cell respreading following mitotic exit. Further analysis shows that while many proteins are lost from focal adhesion complexes during mitotic rounding, integrin-rich contacts remain in place along these tails as well as defining the tips of retraction fibres. These adhesions are functionally impor- tant in RPE1 cells, since these cells fail to divide when removed from the sub- strate prior to entry into mitosis. The restoration of cell-substrate adhesions at anaphase are sufficient to rescue division in control cells. However, adhesions must persist into mitotic exit for division in cells compromised in their ability to construct an actomyosin ring. Division in these cells depends on respreading, since Ect2 RNAi cells fail to divide on small adhesive islands, but successfully divide on larger patterns with the cytoplasmic bridge connecting daughter cells narrowing as they migrate away from one another. Together these results re- veal the importance of coupling adhesion remodeling to mitotic progression.

Full textAbstract:
Par un renoncement au bénéfice de l'accession, la division en volumes opère une scission de l'objet du droit de propriété pour conférer un droit divis sur un immeuble par nature constitué par un volume défini par des cotes en altimétrie et en planimétrie. Il s'agit, sur la base des mêmes références cadastrales, de superposer des propriétés divisées à travers un complexe réseau de servitudes. En intégrant un paysage juridique déjà dense, cette technique superficiaire ordonne de renouveler l'analyse de la nature du bail à construction. La volumétrie doit également être confrontée à la notion d'ensemble immobilier et, s'agissant d'une division de propriété, impose de déterminer sa place aux côtés du régime du lotissement. En tant que mode de gestion, la division en volumes offre une alternative pertinente aux difficultés que connaît le régime de la copropriété et une réponse efficace à la nécessaire cohabitation entre propriété privée et domaine public. En tant que mode de construction, elle est au coeur de difficultés générées par le concours d'une pluralité de maîtres d'ouvrage oeuvrant à la réalisation d'un ensemble indivisible et apporte des solutions originales dans la mise en oeuvre des droits à construire. Fondée sur la rénovation de mécanismes juridiques en apparence éprouvés, la division en volumes résulte d'une construction empirique qui doit être théorisée. L'objet de cette thèse est donc de présenter cette technique et l'impact qu'elle a sur le droit positif en contribuant à renouveler certaines conceptions et en imposant la confrontation de notions qui jusque-là n'interagissaient pasAccording to the accession principle, the soil's owner is also the owner of anything that is upon this soil. By derogating to this principle, the ownership of the soil can be separated from the ownership of anything above this soil – which, in turn, can be subdivided as airspace. On the same cadastral references, different ownerships can be superposed. The mechanism of the right of surface has to find its place in a very dense judicial system. Consequently, this notion has to be confronted to others like construction leases and landparcelling within the framework of housing developments. As an operating system, the airspace building subdivision is a revelant answer to the problem of co-ownership by making the unspecified aliquot part disappear. It's also necessary for the cohabitation of private ownership and public domain. As a mode of construction, this technique is a central issue when different owners take part in the construction of a single, architecturally undividable building. It allows to consider a new and original way to share out the construction rights. Based on the renovation of apparently established juridical mechanisms, airspace subdivision is an empirical method that has to be theorized. The purpose of this thesis is to present this original technique and to show its impact on the positive law, while contributing to refresh some conceptions by confronting notions that has not been confronted before

Approved for public release; distribution is unlimitedIn this thesis, we develop a mixed-integer, linear optimization model to guide the resourcing of submarine maintenance conducted by the U.S. Navys two submarine tenders in the Fifth and Seventh Fleets. We assume maintenance demands are known over a given planning horizon, e.g., one month. Inputs to the model include travel times and costs for fly-away teams and tenders to move to where the maintenance is needed. Each maintenance demand can be divided into tasks with characteristics such as: whether or not tender presence is required; the estimated total number of worker-days required; the maximum number of workers that can simultaneously work on each task; the types of maintenance workers that can perform the task; and task due dates. The models output determines the assignment of personnel to meet the demand at minimum cost, including delay penalties. It also guides personnel travel (as a fly-away team or by tender). In addition, the model can be used to accommodate emergent, unscheduled demands by producing an updated schedule that minimizes the impact on an existing schedule. We test our model on small and realistically sized notional examples to demonstrate the input and output of the models, as well as computational run-times.

Full textAbstract:
The Gram-negative bacterium Escherichia coli is a model system to describe the biochemistry and cell biology of cell division in bacteria. This process can be divided into three major steps. The first step involves the replication of the DNA, followed by an elongation step in which the cells become twice as long. In the last step the elongated cell constricts in the middle and the two daughter cells are separated. The cell division process in E. coli has been extensively studied for at least 50 years and a lot is known, however many details are still vague. New proteins involved in the process continue to be identified and the number of these proteins as well as the interactions among them are not yet fully known. It is therefore not completely understood how the contraction proceeds to form two daughter cells. In this thesis, I have carried out experiments that contribute to our understanding of cell division in E. coli. Using fluorescence microscopy I show that the contraction of the inner membrane in dividing E. coli proceeds in a linear fashion and that the periplasm closes after the cytoplasm. I have also analyzed the oligomeric state of two proteins involved in the cell division and I show that the early cell division protein ZipA can dimerize. This could explain how this protein can bundle FtsZ protofilaments, as it could bridge two protofilaments. Penicillin-binding protein 5 (PBP5) has been found to localize to the septum and it has been suggested to be connected to cell division. I have found that PBP5 forms a homo-oligomeric complex, most likely a dimer. The dimer can be modeled in a back-to-back conformation with the catalytic domains being flexible. This allows PBP5 to reach for pentapeptides of the peptidoglycan at different distances from the membrane. An understanding of the mechanisms used by the cell division proteins and their protein: protein interactions can be a first step towards determining new antibiotic targets.At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 2: Submitted.

Trial division is possibly the simplest algorithm for factoring numbers.The problem with Trial division is that it is slow and wastes computationaltime on unnecessary tests of division. How can this simple algorithms besped up while still being serial? How does this algorithm behave whenparallelized? Can a superior serial and a parallel version be combined intoan even more powerful algorithm?To answer these questions the basics of trial divisions where researchedand improvements where suggested. These improvements where later im-plemented and tested by measuring the time it took to factorize a givennumber.A version using a list of primes and multiple threads turned out to bethe fastest for numbers larger than 10 10 , but was beaten when factoringlower numbers by its serial counterpart. A problem was detected thatcaused the parallel versions to have long allocation times which slowedthem down, but this did not hinder them much.Trial division är en av de enklaste algoritmerna när det kommer till attfaktorisera tal. Problemet med trial division är att det är relativt långsamtoch att det gör onödiga beräkningar. Hur kan man göra denna algoritmsnabbare utan att inte göra den seriell? Hur beter sig algoritmen när denär parallelliserad? Kan en förbättrad seriell sedan bli parallelliserad?För att besvara dessa frågor studerades trial division och dess möjligaförbättringar. Dessa olika förbättringar implementerades i form av flerafunktioner som sedan och testades mot varandra.Den snabbaste versionen byggde på att använda en lista utav primtaloch trådar för att minimera antal ’trials’ samt att dela upp arbetet. Denvar dock inte alltid snabbast, då den seriella versionen som också användeen lista av primtal var snabbare för siffror under 10 10 . Sent upptäck-tes ett re-allokeringsproblem med de parallella implementationerna, meneftersom de ändå var snabbare fixades inte detta problemet.

Litteraturstudien grundar sig i det faktum att vägen till förståelse för innebörden och funktionen av operationer med multiplikation och division är besvärligt för en del elever och lärare. De svenska elevernas låga resultat inom matematik från undersökningarna PISA och TIMSS är även oroande och därför är det av yttersta vikt att forska inom vilka strategier och metoder som faktiskt används i undervisningen om multiplikation, division och dess samband. Syftet med denna studie är att undersöka vad forskning beskriver om multiplikation, division och dess samband, och mer specifikt, att besvara frågeställningarna: vilka strategier och metoder beskriver forskning används i undervisning om multiplikation och division? Samt vilka strategier och metoder beskriver forskning används i undervisning om sambandet mellan multiplikation och division? För att besvara frågeställningarna och uppnå studiens syfte har vi systematiskt tagit fram, analyserat och sammanställt vetenskapliga studier som berör det valda området. Resultatet visar att den strategi som används och upphöjs mest är arrays, dock visar de olika studierna att det finns många olika metoder som lärare kan använda när de arbetar med strategin. Inom vilka strategier och metoder som används för att förklara sambandet mellan räknesätten nämns även arrays som en effektiv metod. Resultatet visar även att forskarna helst ser att man undervisar multiplikation och division tillsammans istället för isär och på så sätt visar sambandet mellan dem. Problematiseringen av resultatet i denna studie är att majoriteten av studier som använts är internationella och därför kan inte resultaten representera hur lärare i Sverige arbetar med det valda området. Vidare forskning inom området kan vara att titta på hur ett fåtal svenska lärare undervisar om sambandet. Slutsatsen för studien är att lärare är i behov av djupare kunskap inom sambandet mellan multiplikation och division och för att få det måste fler strategier och metoder inom ämnet synliggöras.

Effectuer une division arithmétique est un objectif qui se heurte à des obstacles liés à l'apprentissage et à la technique opératoire de la division elle-même. L’étude présentée cherche à déterminer l'origine et la nature des erreurs les plus fréquentes, afin d'analyser les procédures utilisées par les élèves mis en situation d'effectuer des divisions. Nous étudions comment les élèves interprètent l'apprentissage de ce schème, et comment évoluent les significations relatives au sens lui-même. Notre objectif est de déterminer en quoi le choix des différentes divisions permet de contrôler les processus des élèves, et de comprendre le sens qu'ils attribuent à ces opérations. L’exploration des domaines dans lesquels s’inscrivent les concepts mathématiques sera envisagée selon la classification et la réflexion sur le sens que les enfants donnent à la connaissance de l'algorithme. Notre étude de l'histoire de la division permet de distinguer toute une série d’obstacle épistémologique à l'installation de cette notion: la division est un algorithme difficile, qui installe chez les enfants des schèmes résistants, et qui continue à se manifester par des erreurs, certaines nous l'avons vu étant récurrentes. Les obstacles épistémologiques qui nous intéressent pour l'enseignement sont ceux qui apparaissent actuellement comme inévitables soit parce que la connaissance-obstacle est fatalement construite par l'élève au cours de son développement cognitif, ou bien parce qu'elle doit être enseignée pour servir d'appui aux connaissances futures de l'élève. L’histoire montre bien combien cette construction a été lente, difficile, et quelles ont été les résistances qu'elle a rencontrées. On tente ainsi d'expliciter comment le concept de division est venu jusqu'à nous, et d'où il vient, et on se fabrique une réponse plus ou moins plausible ou séduisante, mais sans savoir comment il faut s'y prendre pour obtenir une réponse vraie. Pour schématiser cet état de choses, cela montre la coexistence simultanée de plusieurs perspectivesDoing a division calculation is a target which comes up against obstacles linked with the meaning of the operational technique itself. This research aims to determine the origins and the nature of the most frequent mistakes in order to analyze the procedures used by pupils when they have to divide we will examine how the pupils interpret the learning of this operation. How the meanings are related themselves, and how they evolve. Our objective is to determine how the choice of different divisions makes it possible to check the mental processes of the pupils and to understand the meaning that they give to these calculations. The exploration of the areas to which the mathematical concepts belong will be done according to the classification and reflection on the meaning that the children give to their knowledge of the algorithm. Our study of the history of division allows us to distinguish a whole series of epistemological obstacles which come in the way of the establishment of this notion: division is a difficult algorithm. Which builds up strong "schemes" in children's minds, and continues to reveal itself through mistakes certain of which are recurrent. The epistemological obstacles which are of interest for teaching are those which now seem unavoidable either because the obstacle is inevitably constructed by the pupils during his cognitive development, or because it must be taught, to serve as a support for future knowledge. History shows how slow and difficult this construction has been and the resistance it has come up against. We also attempt to clarify how the concept comes from; and we’ve come up with a more or less plausible answer, without knowing how to go about finding a true answer. To simplify this situation we can say that this shows simultaneous coexistence of several perspectives

Au-delà d'une simple étude des effets du travail sur la famille, ou bien même de l'impact de la vie familiale sur l'activité professionnelle, l'objet de cet ouvrage est de saisir ensemble le travail et la famille et d'en construire une sociologie. Celle-ci permet de rendre compte de la façon dont la famille, par sa composition, ses structures, s'inscrit dans l'emploi et contribue à définir les formes de travail et d'activité économique, tant pour les individus, les groupes ou les institutions que pour les pays. L'analyse montre comment les relations entre la famille et le travail amènent à comprendre ce qui se passe au travers de la gestion de la main-d'oeuvre dans les entreprises, qui semble affecter les individus aux postes de travail, en fonction de leur statut matrimonial; comment les formes que présentent le travail et la famille sont différentes suivant les secteurs économiques (entreprises, service public, travail indépendant). Plus largement, elle aide à repérer les groupes mobiles et à suivre les évolutions, celles de notre pays comme de l'ensemble des sociétés développées, pour lesquelles il ne saurait y avoir d'évolution économique sans évolution familiale. L'analyse, qui s'appuie sur dix années de travaux théoriques et d'enquêtes de terrains, propose une méthode, des concepts, des règles et ouvre un large champ d'études et de recherchesBeyond just a study of the effects of work on family, or even of the impact of family life on work activities, the subject of this book is to apprehend together work and family, and to built up a sociology of that. This one is able to show how family, by its composition, its structures, has a place in employment and contributes to define the forms of work and economic activity; and that also for people, groups or institutions, and countries. The analysis indicates how the relations between work and family lead to understand what happens through the labour force management in the firms, that seems to assign the individuals to the jobs according to their matrimonial status. It shows too, how the forms of work and family are different for the economic sectors (firms, public sector, and self-employment). Largely too, it helps to see precisely the mobile groups, and the evolutions of our society and for the whole developed countries; for these one, it connot be any economic without family development. The analysis is based on ten years of theoritical researches and surveys; it proposes a method, concepts, rules and allows many further investigations

Full textAbstract:
A simulated Pacific herring population (Clupea harengus pallasi) is used to evaluate alternative management strategies of constant escapement versus constant harvest rate for a roe herring fishery. The biological parameters of the model are derived from data on the Strait of Georgia herring stock. The management strategies are evaluated using three criteria: average catch, catch variance, and risk. The constant escapement, strategy provides highest average catches, but at the expense of increased catch variance. The harvest rate strategy is favored for large reductions in catch variance but only a slight decrease in mean catch relative to the fixed escapement strategy.
The analysis is extended to include the effects of persistent recruitment patterns. Stock-recruitment analysis suggests that recruitment deviations are autocorrelated. Correlated deviations may cause bias in regression estimates of stock-recruitment parameters (overestimation of stock productivity), and increase in variation of spawning stock biomass. The latter effect favors the constant escapement strategy, which fully uses persistent positive recruitment fluctuations. Mean catch is depressed for the harvest rate strategy, since the spawning biomass is less often located in the productive region of the stock-recruitment relationship.
It is recognized that management agencies never have perfect information. Management observation error is modeled as uncertainty in spawning biomass estimates, based on data for errors in the measurements of spawn length, width and egg layers. Mean catch is reduced for both strategies. Reductions in the constant escapement strategy are more pronounced, and vary with the assumed form of the assessment error probability distribution.Science, Faculty of

From the position data of 23 drifters over the four years period, 1982 to 1985, the upper layer kinematics of the Northeast Pacific were investigated. The focus of this study was upon the topographic influence, wind forcing, and Rossby waves. The notions of homogeneity and stationarity were applied to both the Eulerian and Lagrangian analysis. A new computational scheme was proposed and tested in order to explicitly take into account the Lagrangian characteristics of the drifter data. The Eulerian analysis showed that the spatial and temporal distributions of the mean current and the mean wind stress were in good agreement. Three of the four eddy kinetic energy maxima found in the region geographically corresponded to topographic features. Also the velocity field of this region appeared to be strongly inhomogeneous, non-stationary, and anisotropic. The results from the Lagrangian analysis showed that the spectral slope for the periods shorter than 5 days followed the -2 law, and suggested that the direct wind forcing was a dominant mechanism for those periods. The spectrum of the eddy component of the velocity appeared to be white for the periods longer than 10 days. The results showed that the linear Rossby waves were not dominant mechanism for upper layer dynamics of this region. The rotary spectra illustrated some evidence of the rotational preference of the cyclonic over anti-cyclonic motions at a period of 10 days. The new scheme provided meaningful information about the eddy component of the velocity.Science, Faculty of

Full textAbstract:
Tryst Tropique questions some of the assumptions that have been made about the heterosexual trajectory described by European desire as it has informed literary, artistic and anthropological representation of the South Pacific. It reads a series of contact encounters and Pacific residencies for their unfolding of European sexual inscription and discovers their inevitable entanglement with problematics of homosexual definition. This thesis arcs between two readings wherein the sexual conduct of Polynesian men both requires and escapes European definition. The first, which settles on the documents of Cook's third voyage, uses British indifference to Hawaiian sodomitical desire to help measure a representational space from whence the European homosexual will emerge (Chapter Two). The next reading considers the erotics of male visibility legible across a number of Marquesan contact texts including Herman Melville's Typee (Chapter Three). Chapter Four discovers that the suspicion of sodomitical misconduct which clouded the career of William Yate, an early nineteenth-century New Zealand missionary, continues to involve twentieth-century commentators in the interpretative dynamics of sexual entrapment. Chapter Five turns to Gauguin's Tahitian writings and paintings to engage with the place of ambivalence in contemporary analyses of colonial discourse. Chapter Six extends the parameters of the thesis in terms of gender and of geography, taking up the controversy generated by Derek Freeman around the early Samoan fieldwork of Margaret Mead. It argues that in the example of Mead's career, we can observe the way in which female sexuality acts as the cipher by which culture multiplies and maintains ignorances and knowledges across the discursive field of sex in both cosmopolitan and primitive locations. The final chapter, which analyses a contemporary documentary representation of Samoan fa'afafine, finds the pertinence or applicability of European sexual description to Polynesian behaviour again at stake, though now we find that the liberal gesture of cultural relativism is co-optable to a homophobia already drilled and proficient in erecting a difference without to forestall a difference within. Reading against the grain of much postcolonial work on the South Pacific, Tryst Tropique finds that it is the male body-whether native or European-not the female, which provides the sexual vanishing point which structures many of these narratives. In each of these Pacific moments a privileged figuration occurs: the body which stands as a placemarker for erotic capacities-both indulged and forsworn-is indicatively male. These inscriptions of masculinity betray a certain amplifying anxiety; the discrepant sexual availabilities recorded in each text break with increasing urgency on the shore of heterosexual and homosexual definition. Even as these Pacific journal keepers, these writers and artists, map identity more and more ferociously onto the known grid of gender, it seems as if the horizon of sexual certainty further and further recedes.
