PRELIMINARY OBSERVATION ON LIVING HABITS OF ACANTHASTER PLANCI (LINNAEUS) AT PULAU TIKUS, SERIBU ISLANDS
No full textDuring the period of June 1975 to August 1975, observations on living habit and some ecological aspects of Acanthaster planci were made at Pulau Tikus, Seribu Islands. The observations, limited to 8 metres deep, were made at the outer reef located south of Pulau Tikus, covering an area of about 4000 square metres. The density of living stony corals and the damaged caused by the feeding activities of A. planci were also studied. The results show that the average numbers of A. planci per month is 20 individuals per 4000 m2. The sizes of the starfish vary between 26-41 cm in diameter and the number of arms between 10 - 18. The moving distance of the starfish is 0.3 - 8 metres in 24 hours. The stony corals affected are Acropora squamosa (BROOK), A. spathulata (BROOK), A. Latistella (BROOK), A. quelchi (BROOK), Fungia sp.. Montipora ramosa BERNARD, Porites sp., DipIoria sp., and Goniatrea sp
Finance and its reform : beyond laissez-faire
No full textThat the financial sector should be liberalized was the orthodox view in the mid-1970s, during a pendulum swing toward reliance on the free market. In the early 1980s, the pendulum swung back to the left, based partly on evidence - especially from Latin America - that overly rapid reform had real costs, and partly on an increased appreciation of financial market failure. Blind adherence to free market principles was no longer appropriate. Now a counter-counterrevolution is in sight, with some swing back toward the view that the market makes a mess of it, but the government makes it even worse. The authors agree that market-oriented financial systems appear to do a better job than systems with extensive government involvement, but contend that the assumption that perfect competition will solve all problems in finance - especially in banking - can be dangerous. Information problems, implicit or explicit government guarantees associated with the payments system make banks unique. Governments implicitly recognize banking's uniqueness - few allow just anyone to enter banking - but public pronouncements and observers'recommendations often favor a move to more competition. Perfect competition, however, is optimal under the assumption, among others, of no government guarantee. In fact, most governments differ only in how explicit they are about their deposit insurance schemes. The financial reforms most likely to succeed are those that give banks an incentive to engage in safe and sound banking. When excessive competition is allowed, the charter value of banking diminishes to the point that it is no longer profitable for bankers to behave prudently. A consideration of finance's role, and a look at how reforming economies have fared, suggest also that gradual reform is often to be preferred in this domain. Deregulation of credit markets and interest rates can be counterproductive in unstable macroeconomic conditions and when banks are unsophisticated or have weak balance sheets. And changes in the charter value may evolve only slowly after reform. Faster progress and greater efforts should be made, however, in bank supervision and regulation and in institutional development, including accounting, auditing, legal and judicial reform, and training (of bankers and other finance professionals). In sum, many economies would benefit from less government intervention in financial markets, but the prescription should not be abrupt or total government withdrawal from the financial sector. Rather than intervening heavily in credit allocation decisions, governments should focus on doing what only they can do: providing an enabling environment for the private financial and nonfinancial sectors, and ensuring that financial operations are safe and sound.Environmental Economics&Policies,Banks&Banking Reform,Financial Intermediation,Economic Theory&Research,Financial Crisis Management&Restructuring
A numerical solution for nonlinear heat transfer of fin problems using the Haar wavelet quasilinearization method
No full textThe aim of this paper is to study the new application of Haar wavelet quasilinearization method (HWQM) to solve one-dimensional nonlinear heat transfer of fin problems. Three different types of nonlinear problems are numerically treated and the HWQM solutions are compared with those of the other method. The effects of temperature distribution of a straight fin with temperature-dependent thermal conductivity in the presence of various parameters related to nonlinear boundary value problems are analyzed and discussed. Numerical results of HWQM gives excellent numerical results in terms of competitiveness and accuracy compared to other numerical methods. This method was proven to be stable, convergent and, easily coded. © 2019 The Author
Peran Manajemen Personalia Dalam Mendorong Perfoma Guru PAI di Sekolah Menengah Pertama
No full textThe quality of education in Indonesia is arguably still very low. This is very influential for the younger generation in the future, especially for educators, improving the quality of education is very important to do because there are many inhibiting factors to achieve the quality of education in Indonesia until now. This is in line with the research objective, which is to describe the teacher's role in supporting and improving the quality of education at SMP N 3 Godean. This research was conducted at SMP N 3 Godean. This research is a qualitative research using a descriptive approach. The research instrument used interviews. Respondents research vice principals and teachers BK. By using this approach, the author can describe the role of personnel management in improving teacher performance
