In the industrial engineering community, it’s a well-known adage that focusing on process can help achieve better results. In this second of a series of papers, we’ll focus on the process of simulation testing and outline how improving your testing process can lead to better results for your projects. We’ll consider model building as a software development exercise, and discuss how best practic...

In his 1981 Baseball Abstract [8], Bill James posed the following problem: suppose two teams A and B have winning percentages a and b, respectively, having played equally strong schedules in a game such as baseball where there are no ties. If A and B play each other, what is the probability p(a, b) that A wins? This question is perhaps more relevant to other sports, because in baseball the outc...

James Tanner spent much of his childhood abroad, in the baggage train of the British Army; when he was 9 years old the family returned to their home in east Devon and he began his schooling. He attended Marlborough College from 1934 to 1938 on a scholarship reserved for the sons of Army officers. Having specialised first in modern languages and then in mathematics and engineering, he found hims...

Hamilton begins his criticism by stating that there is a philosophical distinction between the two methods for dating cycles and concludes that the method we use “leaves vague and intuitive exactly what this algorithm is intended to measure”. Nothing is further from the truth. Ask yourself, what is a recession? Common usage suggests that it is a decline in the level of economic activity that la...

The idea that geography affects economic performance is an old one. Easterly and some other economists have taken a particular position about the relationship between geography and development. They too have recognized the high correlation of a country’s poverty with being in a malaria-transmission region, or being landlocked, or being in an ecological zone leading to low food productivity. Tho...

Multidimensionality of concepts in multidisciplinary domains is a problem terminographers have to deal with. We apply Corpus Pattern Analysis (CPA; Pustejovsky, Hanks, & Rumshisky, 2004) to extract conceptual dimensions according to context. The dynamic nature of these concepts is exemplified with the case study of SAND. On the other hand, knowledge patterns (KPs) often convey different concept...

The paper presents a prototype lexicalist Machine Translation system (based on the so-called ‘Shake-and-Bake’ approach of Whitelock (1992)) consisting of an analysis component, a dynamic bilingual lexicon, and a generation component, and shows how it is applied to a range of MT problems. Multi-Lexeme translations are handled through bi-lexical rules which map bilingual lexical signs into new bi...

This paper reports on my replication of the 1997 Sachs and Warner resource curse working paper. Exact pure replication is achieved. A test for statistical replication shows that some of the Sachs and Warner results attempting to determine the cause of the resource curse are not robust to the country sample. A test for scientific replication shows that findings of the resource curse are not sens...
