Fifty Years of Development Economics: From Planning to Liberalization Essay in Honour of Prof. P.R.Brahmanande

Fifty Years of Development Economics, Essays in Hon­our of Professor P.R. Brahmananda, Editors A. Vasedevan, D.M. Nachane, A.V. Karnik, Foreword Lord Meghnad Desai, Himalaya Publishing House, Mumbai 400 004, First Edition - 1999. This Volume is a collection of 30 essays, writ­ten in honour of Professor P. R. Brahmananda, a dis­tinguished economist in India. The essays in this book focus on a number of issues such as theory and meas­urement, Indian policy framework, snictural reforms, regional perspectives and provide rich insight on vari­ous subjects. The book also documents empirical stud­ies researched by well-known economists. The first part of the book with 8 chapters deals with theory and measurement of money, inflation etc.. In this part, Nachne's paper on "Commodity Stand­ards: Resurrection of a Classical Theme" revisits the issues relating to the concept of money standard and questions, the role of the Govenment in controlling money. The author, while reviewing the role of gov­ernment in controlling the monetary policy in histori­cal retrospection, examines a umber of alternative proposals. He chooses, amongst others, commodity standard, and analyses it to find out its relevance to modetary policy. His contribution lies in explaining the Black-Fama-Hall (BFH) model-Commodity Basket Model. This model has been discounted as it does not take into account expextations and has difficulties in choosing the commodities for the basket. The BFH model has a few advantages like a stable unit of ac­count, subjects the government to financial discipline, can stipulate financial innovations and can insulate the economy from cyclical fluctuations originating domes­tically. Nachne's contribution lies in simplifying the analysis on the difficult subject. Inflation has been a long drawn riddle in many countries like Brazil, Turkey, India. Control of infla­tion has been enforced in many countries to bring macro economic stability with high economic growth. Vasudevan, Bhoy and D hall have tried to trace equi­librium between inflation and growth rate in the In­dian context. They reached a conclusion that inflation, growth trends and their volatility, when analysed si­multaneously, reveal that a moderate rate of inflation on an average centered between 6 to 8 per cent in In­dian economy with low volatility, led to high growth rates. The authors have used regression robust error technique after taking recourse to a number alterna­tive empirical modes as suggested in the literature. The findings of the present exercise indicate that the thresh­old rate of inflation in the Indian context could be about 6 per cent; the output neutral inflation could be 4 per cent. The output effects are positive but marginally different from one another for the 5, 6 and 7 per cent inflation regimes. The negative output effects occur after 10 per cent inflation rate.

Sales prediction on e-commerce platform, by using data mining model

In this paper we applied twinning algorithm for product that are sold via e-commerce platform. To establish relatively homogenous product groups that were on sale on this e-commerce platform during the last year, it was necessary to form predictive mathematical model. We determined set of relevant variables that will represent group attributes, and we applied K-means algorithm, Market Basket model and Vector Distance model. Based on analysis of basic and derived variables, fixed number of clusters was introduced. Silhouette index was used for the purposes of detecting whether these clusters are compact. Using these cluster separations, we created models that detect similar products, and try to analyze probability of sales for each product. Analysis results can be used for planning future sales campaigns, marketing expenses optimization, creation of new loyalty programs, and better understanding customer behavior in general.

Pengaruh Model Pembelajaran Jigsaw Terhadap Peningkatan Kemampuan Drible Bola Basket

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran jigsaw terhadap pengingkatan kemampuan drible bola basket. Model penelitian yang digunakan adalah menggunakan metode eksperimen dengan desain one group pre test post test desaign. Sampel yang digunakan adalah siswa kelas VIII. Hasil penelitian menujukan bahwa moel pembelajaran jigsaw dapat meingkatkan hasil drible dalam permainan bola basket. Peningkatakan ini dilandaskan pada model pembelajaran kooperatif Jigsaw, dimana setiap siswa menjadi anggota kelompok asal (home group) dan juga sebagai kelompok ahli (expert group) Siswa dalam kelompok ahli bertanggung jawab terhadap penguasaan materi yang menjadi bagian yang dipelajari dan berkewajiban mengajarkan kepada siswa lain dalam kelompoknya. Selain itu, siswa bekerja dengan sesama siswa dalam suasana kooperatif dan mempunya banyak kesempatan untuk mengolah informasi dan meningkatkan keterampilan berkomunikasi Dengan asumsi ini maka hasil drible dalam permainan bola basket akan meningkat, hal ini di tunjukan dengan hasil penghitungan uji-t diperoleh nilai t-hitung sebesar 6,31.

UPAYA MENINGKATKAN KETERAMPILAN DRIBBLE DENGAN PENERAPAN MODEL LATIHAN KELINCAHA

Penelitian ini bertujuan meningkatkan keterampilan dribble bola basket dengan penerapan model latihan kelincahan. Jenis penelitian yang digunakan untuk menjawab tujuan penelitian tersebut adalah Classroom Action Research atau penelitian tindakan kelas (PTK). Subjek penelitian ini adalah siswa kelas VIII B SMPN 10 Kota Bengkulu yang berjumlah 24 orang. Yang terdiri dari 12 siswa putra dan 12 siswa putri. Hasil penelitian pada pra-siklus diketahui bahwa sebagian besar siswa belum memahami teknik dribble, sehingga hasil tes keterampilan dribble yang diperoleh siswa sebesar 20.8% kategori baik, 16.6% kategori cukup, 62.5% kategori kurang. Pada siklus pertama dengan penerapan model latihan kelincahan, siswa memperoleh nilai rata-rata sebesar 54.2% kategori baik, 25% kategori cukup, 20.8% kategori kurang. Pada siklus kedua terjadi peningkatan keterampilan dribble siswa sebesar 79.2% kategori baik, 16.6% kategori cukup, 4.2% kategori kurang. Meningkatnya keterampilan dribble siswa dalam permainan bola basket sebagai pengaruh dari penerapan model latihan kelincahan. Berdasarkan hasil di atas maka disimpulkan bahwa penerapan model latihan kelincahan terbukti dapat meningkatkan keterampilan dribble dalam permainan bola basket.Kata kunci: Keterampilan Dribble Bola Basket, Model Latihan Kelincahan

Basket-Type Catheters: Diagnostic Pitfalls Caused by Deformation and Limited Coverage

Whole-chamber mapping using a 64-pole basket catheter (BC) has become a featured approach for the analysis of excitation patterns during atrial fibrillation. A flexible catheter design avoids perforation but may lead to spline bunching and influence coverage. We aim to quantify the catheter deformation and endocardial coverage in clinical situations and study the effect of catheter size and electrode arrangement using an in silico basket model. Atrial coverage and spline separation were evaluated quantitatively in an ensemble of clinical measurements. A computational model of the BC was implemented including an algorithm to adapt its shape to the atrial anatomy. Two clinically relevant mapping positions in each atrium were assessed in both clinical and simulated data. The simulation environment allowed varying both BC size and electrode arrangement. Results showed that interspline distances of more than 20 mm are common, leading to a coverage of less than 50% of the left atrial (LA) surface. In an ideal in silico scenario with variable catheter designs, a maximum coverage of 65% could be reached. As spline bunching and insufficient coverage can hardly be avoided, this has to be taken into account for interpretation of excitation patterns and development of new panoramic mapping techniques.
