Tidak adanya peningkatan prestasi siswa SMA 3 Siak Hulu dalam KSN bidang kimia tingkat provinsi dan kelulusan UTBK perlu segera diatasi. Selain itu, paradigma pada sebagian besar yang menganggap merupakan matapelajaran sulit abstrak membuat kurang termotivasi untuk mengikuti pembelajaran terlebih lagi kegiatan tambahan berkaitan dengan kimia. Permasalahan ini diatasi, salah satunya melalui prog...

Despite the repeatedly raised criticism that findings in economic games are specific to situations involving trivial incentives, most studies that have examined the stake-size effect have failed to find a strong effect. Using three prisoner's dilemma experiments, involving 479 non-student residents of suburban Tokyo and 162 students, we show here that stake size strongly affects a player's coop...

The new era we face is defining and achieving useful results for all stakeholders: including both internal and external partners. And we must prove the value we add in terms of empirical data about what we deliver, what it accomplished, and what value it added for all stake-holders (not just the value it added to our team, our department, or our organization, but to the entire system of interna...

We study cryptocurrency protocols that do not make use of Proof of Work. Such protocols commonly rely on Proof of Stake, i.e. on mechanisms that extend voting power to the stakeholders of the system. We offer analysis of existing protocols that have a substantial amount of popularity. We then present our novel pure Proof of Stake protocols, and argue that the they help in mitigating problems th...

NeuCoin is a decentralized peer-to-peer cryptocurrency derived from Sunny King’s Peercoin, which itself was derived from Satoshi Nakamoto’s Bitcoin. As with Peercoin, proof-of-stake replaces proof-of-work as NeuCoin’s security model, effectively replacing the operating costs of Bitcoin miners (electricity, computers) with the capital costs of holding the currency. Proof-of-stake also avoids pro...

In 2009, Satoshi Nakamoto introduced the Bitcoin cryptocurrency[Nak09], an online currency system which allowed peer-to-peer transfer of digital tokens. To ensure a consistent view of token ownership, Nakamoto used a public ledger which can be replicated and validated by all network participants. To avoid a single point of failure, this ledger is authenticated using a dynamic membership multipa...

We undertake a generalization of the cumulative sum of squares (CUSQ) test to the case of non-stationary autoregressive distributed lag models with quite general deterministic time trends. The test may be validly implemented with either ordinary least squares residuals or standardized forecast errors. Simulations suggest that there is little at stake in the choice between the two in the unit ro...
