SOEs have a strategic function. Throughout the course of Indonesian economic development, SOEs have acted as an agent ofdevelopment. SOEs have been the main provider of goods and services for consumption, and for inputs required forfurther production process, such as powertelecom-municationoil and gasfertilizesand land, sea, and air transportation. Total assets of SOEs are recorded at around US$ 140 billionthe produc-tion accounts for about 15% of GNPand SOE\u27s employ more than one million personnel. In brief, one can say that SOEs in Indonesia are the prime market movers. In anticipation of globalism, the government, under Presidential Instruction No. 5/1988, has set out policy guidelines to privatize SOEs. Privatization does not necessarily mean the transfer of ownership to the private sector, but also covers other ways such as build operate and transfer (BOT), build operate and own (BOO), contract management, and joint operation. But the jewel of privatization is going-Public. Why go-public? The reason is that by selling shares on the capital market, several important goals may simultaneously be attained: Funds are generated for GOI to repay the high-cost foreign debt and for the SOEs to expandthe efficiency of SOEs is enhancedcapital is widely distributed among more peopleand, the domestic capital market grows. So far four SOEs entered in the market -- PT Semen Gersik, PT Indosat, PT Tambang Timah and PT Telekomunikasi Indonesia. Others such as PT Bank BNI (banking company), PT Krakatau Steel (steel producer) and PT Jasa Marga (toll road operator) and PLN (power company), will join in the market once preparations are finalized . Movement in the privatization program seems moderate, since for an SOE to be privatized, in most cases, a series of regulatory issues must be streamlined before hand. Privatization of the SOEs is an on-going process, and the GOI is committed to continuing the privatization program in an effort make all SOEs more efficient and competitive, and to attain other important goals

Pengaruh Kepribadian Pemimpin Terhadap Struktur Organisasi = The Influence of Leader\u27s Personality on Organization Structure

Research on the determinant of organization structure has been dominated by using traditional determinant (size, technology, complexity, and environmental uncertainty). Consequently, contribution of using traditional determinant has limited (Bassett & Carr,1996). Focusing on psychological determinant of organization structure, this research examines the influence of leader\u27s need for achievement and internal locus of control on dimensions of organization structure (centralization, formalization, and integration). Data were collected from 56 leaders of best small-medium enterprises in Indonesia, according to Accenture. Hierarchical regression analysis were used to test hypothesis. In general, result supported that personality of leaders influenced organization structure. Need for achievement negatively influenced centralization, and positively influenced integration. Internal locus of control positively influenced formalization. Nevertheless, this research cannot identify the influencing of interaction of traditional determinant (size) and psychological determinant (need for achievement and internal locus of control). By emphasizing the role of leader\u27s personality on organization structure, this research suggests practical implementations for both practitioners and researcher. Key Words: Personality, Leader, Organization Structur

Assessment of a Siloxane Poly(Urethane‐Urea) Elastomer Designed for Implantable Heart Valve Leaflets

Synthetic polymer leaflets in prosthetic cardiac valves hold the potential to reduce calcification and thrombus, while improving blood flow, durability, and device economics. A recently developed siloxane poly(urethane‐urea) (LifePolymer™, LP) exhibits properties essential for heart valve leaflets, including low dynamic modulus, high tensile strength, minimal creep, and excellent biostability. LP properties result from carefully designed “linked co‐macrodiol” chemistry that maximizes silicone content and virtual crosslinks between soft and hard phases. Characterization of multiple commercial batches demonstrates a robust synthesis process with minimal variation. Extensive ISO 10993‐based biocompatibility testing resulted in no observable toxicity or other adverse reactions. An ex vivo AV shunt thrombogenicity investigation revealed nearly undetectable levels of platelet attachment and thrombus formation on LP surfaces. Chronic ovine implantation of prototype heart valves with LP leaflets showed no differences in thrombogenicity or systemic tissue response when compared to a clinically standard tissue‐based valve. Toxicological risk assessment, based on extractables and leachables analysis of LP‐based heart valves, confirmed minimal toxicological risk. Lastly, 24‐week, strain‐accelerated in vivo LP biostability testing confirmed previous favorable in vitro biostability findings. These studies demonstrate that this newly developed elastomer exhibits ideal biomaterial properties for the flexible leaflets of a totally synthetic heart valve replacement

Interval analysis applied to dielectric spectroscopy: a guaranteed parameter estimation

Dielectric spectra of materials are often difficult to analyze since the common software algorithms and line shape functions do not always provide unambiguous data for the fitted parameters. In particular, this article deals with epoxy/ceramics nano-prepolymers studied by dielectric spectroscopy. In this situation, both system (the prepolymer with nanofillers) and method (the dielectric spectroscopy) are complex. Taking into account the experimental error of each data point in the measured dielectric spectrum, the sofware based on a global optimization algorithm which uses interval analysis, provides a confidence interval for every parameter of the dielectric function implemented in the software. Then, this software is able to deliver and guarantee the number of relaxation processes even if they are in part masked by other phenomena like conductivity or electrode polarization

Ion Transport in Pendant and Backbone Polymerized Ionic Liquids

Polymerized ionic liquids (PILs) are single-ion conductors in which one of the ionic species is tethered to the polymer chain while the other is free to be transported. The ionic species can either be directly incorporated into the polymeric backbone (backbone PILs) or placed as pendant groups to the chain (pendant PILs). Here, we examined the morphology, conductivity, and rheology of imidazolium-based pendant and backbone PILs. We found that pendant PILs yielded higher ionic conductivity when scaled to Tg, but backbone PILs exhibited higher ionic conductivity on an absolute temperature scale, likely because of differences in the Tgs of the two systems. We also found that ion transport for backbone PILs was coupled to the segmental dynamics below Tg, where the decoupling of ionic conductivity from segmental relaxation was observed for pendant PILs. The results of this study will help the community to better understand the role of the PIL structure on conductivity to work toward the ultimate goal of designing high-performance solid polymer electrolytes

POM Mechanical Properties

Thanks to its high degree of crystallinity, polyoxymethylene (POM) homopolymer exhibits high mechanical properties of strength, stiff ness and creep. In the case of POM copolymer, the strength and stiff ness are slightly lower because of its lower degree of crystallinity. Furthermore, the use domain ranges from -30°C to 150°C which allows various applications. More specifi cally to the POM, friction properties are excellent due to oxygen contained in the POM monomer. Th e major drawback of POM homopolymer is its brittleness at RT compare to polyolefi ns, typically nominal strain at break values are close to 20%. To improve mechanical properties at failure, diff erent strategies can be adopted as POM copolymer have lower crystallinity degree (strain at break close 70%) or added polyurethane in POM matrix (100ST from DuPont for instance). However, we will see that these strategies lead to a decrease in the material’s stiff ness. Lastly, another possible way is the use of specific processing conditions to induce oriented morphology. We will review all these aspects. This chapter is divided in two major parts: the first part is devoted to shortterm mechanical properties as elastic properties as a function of temperature and morphology aspects, failure properties and the diff erent strategies to improve them. The second part aims to present long-term properties such as creep behavior and modifi cations induced by aging, leading to an embrittlement of the POM limiting its lifetime

Mathematical modelling of rock bolt reinforcement

summary:Rock bolts as construction elements are often used in underground civil engineering projects. This work deals with their numerical modelling. Aydan special finite elements for the description of rock bolts and hexahedral quadratic finite elements for the description of rock massif were used. A code for the computation of stiffness matrices and right hand sides of these elements was developed. The code was tested on several simple test examples and their results were compared with the analytical solution. Stresses in a rock massif in the surrounding of an excavation reinforced by rock bolts were computed. The results show that the use of rock bolts can reduce the areas of maximal mechanical stress in the vicinity of excavations
