Introduction : Triggered by the Asian currency crisis, Indonesia plunged into the times of violent change. With the downfall of the long-standing Soeharto rule in May 1998, changes of the state order started with great magnitude and rapidity under a new banner of “reformasi” (reform). What changes have occurred in this reformasi period? What do these changes signify? To answer these questions, it would be better to have a certain yardstick to allow us comparison. One possibility is to use a yardstick of history. What picture will emerge if we see the current array of changes in long-term historical perspectives is a main question of this paper. This paper intends to provide a bird’s-eye picture illustrating where in the Indonesian history the current restructuring of the state order is located. Rather than focusing on a specific area, I here attempt to broaden our outlook on Indonesia’s political, economic and social arenas in order to identify what are happening in these arenas, how they are mutually related, and what those events signify in the Indonesia’s historical context.

The aim of the present study was to examine the effect of sodium bicarbonate ingestion on consecutive "all out" sprint tests, analyzing the acid-base status and its influence on performance and perceived effort. Ten elite bicycle motocross (BMX) riders (20.7 ± 1.4 years, training experience 8-12 years) participated in this study which consisted of two trials. Each trial consisted of three consecutive Wingate tests (WTs) separated by 15 min recovery. Ninety minutes prior to exercise subjects ingested either NaHCO(3) (-) (0.3 g kg(-1) body weight) or placebo. Blood samples were collected for the assessment of blood acid-base status: bicarbonate concentration ([HCO(3) (-)]), pH, base excess (BE) and blood lactate concentration ([La(-)]). Performance variables of peak power (PP), mean power (MP), time to peak power and fatigue index were calculated for each sprint. Significant differences (p < 0.05) were observed in acid-base variables [pH before WT1: 7.47 ± 0.05 vs. 7.41 ± 0.03; [HCO(3) (-)] before WT1: 29.08 ± 2.27 vs. 22.85 ± 0.24 mmol L(-1) (bicarbonate vs. placebo conditions, respectively)], but there were not significant differences in performance variables between trials [PP WT1: 1,610 ± 373 vs. 1,599 ± 370 W; PP WT2: 1,548 ± 460 vs. 1,570 ± 428 W; PP WT3: 1,463 ± 361 vs. 1,519 ± 364 W. MP WT1: 809 ± 113 vs. 812 ± 108 W; MP WT2: 799 ± 135 vs. 799 ± 124 W; MP WT3: 762 ± 165 vs. 782 ± 118 W (bicarbonate vs. placebo conditions, respectively)]. Rating of perceived effort (RPE) was not influenced nor ratings of perceived readiness. Sodium bicarbonate ingestion modified significantly the blood acid-base balance, although the induced alkalosis did not improve the Wingate test performance, RPE and perceived readiness across three consecutive WTs in elite BMX cyclists.

AlGaAs/GaAs-based laser power PV converters intended for operation with high-power (up to 100 W/cm(2)) radiation were fabricated by LPE and MOCVD techniques. Monochromatic (lambda = 809 nm) conversion efficiency up to 60% was measured at cells with back surface field and low (x = 0.2) Al concentration 'window'. Modules with a voltage of 4 V and the efficiency of 56% were designed and fabricated.

The issue: Excluding cartels, most investigations into suspected infringements of European Union competition law are resolved with ‘commitment decisions’. The European Commission drops the case in exchange for a commitment from the company under investigation to implement measures to stop the presumed anti-competitive behaviour. Commitment decisions are considered speedier than formal sanctions (prohibition decisions) in restoring normal competitive market conditions. They have a cost, however: commitments are voluntary and are unlikely to be subject to judicial review. This reduces the European Commission’s incentive to build a robust case. Because commitment decisions do not establish any legal precedent, they provide for little guidance on the interpretation of the law. Policy challenge: The European Commission relies increasingly on commitment decisions. More transparency on the substance of allegations, and the establishment of a higher number of legal precedents, are however necessary. This applies in particular to cases that tackle antitrust issues in new areas, such as markets for digital goods, in which companies might find it difficult to assess if a certain behaviour constitutes a violation of competition rules. To ensure greater transparency and mitigate some of the drawbacks of commitment decisions, while retaining their main benefits, the full detail of the objections addressed by the European Commission to defendants should be published.

We present a 5.3-Myr stack (the ''LR04'' stack) of benthic d18O records from 57 globally distributed sites aligned by an automated graphic correlation algorithm. This is the first benthic delta18O stack composed of more than three records to extend beyond 850 ka, and we use its improved signal quality to identify 24 new marine isotope stages in the early Pliocene. We also present a new LR04 age model for the Pliocene-Pleistocene derived from tuning the delta18O stack to a simple ice model based on 21 June insolation at 65 N. Stacked sedimentation rates provide additional age model constraints to prevent overtuning. Despite a conservative tuning strategy, the LR04 benthic stack exhibits significant coherency with insolation in the obliquity band throughout the entire 5.3 Myr and in the precession band for more than half of the record. The LR04 stack contains significantly more variance in benthic delta18O than previously published stacks of the late Pleistocene as the result of higher resolution records, a better alignment technique, and a greater percentage of records from the Atlantic. Finally, the relative phases of the stack's 41- and 23-kyr components suggest that the precession component of delta18O from 2.7-1.6 Ma is primarily a deep-water temperature signal and that the phase of d18O precession response changed suddenly at 1.6 Ma.
