The operation of the ship is quite dense requires the procurement and
regular maintenance so that ship operations are not hampered and problematic.
The obligation of the company as the owner of the vessel shall provide spare parts
and ship equipment that support the maintenance of the vessel. The Company
forms part of its organizational structure responsible for the maintenance of all
shipments, namely purchasing logistics
In this study the authors explain the role of purchasing logistics in
supporting the operational activities of PT.Dian Bahari Sejati south Jakarta and
the constraints faced and the efforts made by purchasing logistics in the provision
of spare parts and ship equipment. The method used in the writing of this thesis is
descriptive qualitative method. The data collected by the authors are sourced
from people who are related to the problem of purchasing logistics and data
results of author observation.

Gray-box modeling of resistive wall modes with vacuum-plasma separation and optimal control design for EXTRAP T2R
No full textThis paper presents a graybox methodology to model the resistive wall mode instability by combining first principle approach and system identification technique. In particular we propose a separate vacuum and plasma modeling with cascade interconnection. The shell is modeled using CARIDDI code which solves the 3D integral formulation of eddy current problem, whereas the plasma response is obtained empirically by system identification. Furthermore the resulting model is used to design an optimal feedback control. The model and feedback control is validated experimentally in EXTRAP T2R reversed-field pinch, where RWMs stabilization and non-axisymmetric mode sustainment is considered. </p
The effects of competition on market segment selection
No full textIn this research, we investigate the dynamics of firms' segment selection, in which segments a firm decides to enter and compete, and in which segments a firm decides to exit, from a competitive perspective. Specifically, we examine how firms make segment selection by simultaneously considering seemingly contradictory effects: the segment competitive condition predicts that firms avoid competition and imitation effects that influence firms to imitate each other and to cluster together. To investigate this, we observed positional moves of firms operating in the U.S. automobile industry between 1950 and 1993 (annual panel data) with around 11,000 items of complete observations with an unbalanced time series cross sectional panel. The data recorded 723 segment entries and 627 segment exits. A discrete time event history analysis with time-varying independent variables was employed to estimate the effects of the independent variables on the probability of a company conducting segment entry or exit in a specific segment. The results suggest that although firms tend to avoid their competitors, the fear of losing market opportunity makes firms follow and imitate each other, and thus mitigate their effort to reduce the competition.Ph.D.Includes bibliographical referencesby Setiadi Uma

Losess is a problem that always arises in the process of loading, unloading and transporting. With these efforts should be made and constraints faced to suppress the depreciation charge. This is because the implementation and supervision of loading and unloading unfavorable, inaccuracy in the measurement and calculation as well as measuring tools used not standard
The theoretical basis that the author used in writing this essay describes the efforts to suppress the depreciation charge of fuel oil at the port of loading and unloading as well as to identify and overcome in MT. Bumi Indonesia This thesis also describes the terms of shrinkage, measurement, measurement systems, the intent and purpose of measurement, calculation of the ship, the calculation of the amount of oil that has been published, as well as the procedures for calculation of oil onboard.
The method used writer is a descriptive qualitative research method, so that the author tried to explain the results of all the studies and research on an object obtained.
From the results of the study authors found shrinkage can not be minimized because they have not implemented procedures for implementing and monitoring the activities of dismantling and loading, as well as less rigorous in measuring and calculating the amount of the charge and not standard measuring tool used so that shrinkage occurs frequently. In order to suppress the depreciation charge of the implementation of the loading and unloading procedures performed well and improve supervision of loading and unloading. Efforts to overcome the obstacles encountered in efforts to suppress the shrinkage is more rigorous in measuring and calculating the amount of the charge, and should be standard measurement tools used during the measurement of the charge.
The conclusions of this thesis is the contraction still occurs in MT. Bumi Indonesia due to the implementation of the dismantling and loading are not implemented properly and the lack of supervision at the time of loading and unloading, as well as the constraints faced was less thorough in measuring and calculation. Suggestions author, with good implementation and monitoring and to overcome the obstacles encountered to be more careful in the measurement and calculation and measurement tools are standard
Developing countries'participation in the World Trade Organization
No full textIn the 1960s and 1970s developing countries viewed UNCTAD (United Nations Conference on Trade&Development) rather than the GATT (General Agreement on Tariffs&Trade) as the main institution through which to promote their interests in international trade. But beginning with the Uruguay Round in the mid-1980s, their attitude changed, many more of them became members of the GATT, and a significant number played an active role in negotiations. The author analyzes developing countries'representation and participation in the World Trade Organization (WTO) as of mid-1997 to determine how developing countries can effectively promote their interests and discharge their responsibilities under the rules and agreements of the new organization. He concludes that although many developing countries are actively participating in the new process, more than half of the developing countries that are members of the WTO participate little more than they did in the early 1980s and have not increased their staffing, despite the vastly greater complexity of issues and obligations. Institutional weaknesses at home are the main constraints to effective participation and representation of their interests at the WTO. To make their participation more effective, he recommends that the developing countries establish adequately staffed WTO missions based in Geneva; failing that, pooling their resources and representation in Geneva; and being sure to pay their dues, which are typically small. He also recommends that the international community place higher priority on programs of assistance in support of institutional development of poorer countries aimed at enhancing their capacity to participate in the international trading system and the WTO -- and that the WTO review its internal rules and procedures to ensure that inadvertently they do not make developing countries participation more difficult.Economic Theory&Research,Decentralization,Economic Conditions and Volatility,Country Strategy&Performance,Labor&Employment Law,Trade and Services,Poverty Assessment,Economic Theory&Research,World Trade Organization,Country Strategy&Performance

No full textDevelopment of natural gas and pipeline capacity markets in the United States
No full textDeregulation of the U.S. natural gas industry has been under way since the late 1970s. The industry was deregulated to create competitive markets in natural gas and its pipeline transportation, in the expectation that competition would guide transactions toward a more efficient outcome. The author provides an overview of the deregulation process and its effect on the development and functioning of natural gas and gas transportation markets in the United States. He analyzes the trading of pipeline capacity in primary and secondary markets and the regulation of pipeline transportation, identifies mechanisms that pipeline companies use to coordinate bilateral transactions, and summarizes deregulation's main achievements in the U.S. natural gas industry. Industry achievements in the past 15 years show that expectations were not realistic. The United States enjoys a highly competitive interstate transportation market. Both markets have benefited from the deregulation of natural gas production and marketing and the liberalization of natural gas prices. Introducing open access to interstate pipelines and their unbundling from gas sales has allowed end users to participate in the efficiency gains in upstream markets. All this has contributed to declining retail prices for all major consumer categories. Deregulation is far from complete, however. Current regulation of interstate pipeline companies and the secondary transportation market does not promote efficient allocation of transportation contracts. Flexible pricing of transportation contracts should be introduced in both the primary and secondary transportation markets. But deregulation of retail markets remains the most important task and the bigger challenge facing industry regulators. Small-volume end users (such as residential or commercial customers) are captive to local distribution utilities, without access to competitive wholesale markets. All end users should be able to choose a natural gas supplier and receive natural gas at the minimum cost to society.Oil&Gas,Water and Industry,Markets and Market Access,Economic Theory&Research,Environmental Economics&Policies,Transport and Environment,Water and Industry,Oil Refining&Gas Industry,Oil&Gas,Carbon Policy and Trading
