Can a temporary economic shock to an important local industry influence long-run city population? To answer this question I study the large temporary shock to British cities caused by the U.S. Civil War (1861-1865), which reduced cotton supplies to Britain’s important cotton textile industry. I show that this event temporarily reduced the growth rate of cities specialized in cotton textile prod...

Pangola digitgrass (Digitaria decumbens Stent.) can be used as a pasture grass or it can be harvested as hay. I t originated in Africa and has been in t roduced to other tropical and subtropical areas of the world. Winchester and Haysl ip (5) repor ted that the grass e l iminated populat ions of the root&not nematode, Meloidogyne incognita acrita Chitwood and Oteifa, 1952. Overman (3) sampled 7...

In this paper, we propose an analytical and methodological comparison between two of the most known distance-based methods in the evaluation of the geographic concentration of economic activity. These two methods are Ripley’s K function, a cumulative function popularised by Marcon and Puech (2003) that counts the average number of neighbours of each point within a circle of a given radius, and ...

This paper aims to present Friedrich Nietzsche’s critique of Christianity as a Western example that reconfirms the necessity for man’s inner development up to the stage of the Completest Self (nafs-i safiyya). With the advent of Christianity and the resultant triumph of its “morality of slave” (1886, sec. 260), the “death of God” (1882) becomes the “fundamental event of Western history” and its...

Industrial agglomeration is a highly prominent geographical feature of economic activities, and it an important research topic in geography. However, mechanism-based explanations industrial often differ due to failure distinguish properly between the spatial distribution industries stages agglomeration. Based on micro data from three national censuses, this study uses Duranton-Overman (DO) inde...

W e have examined the binding of the oligonucleotide ~ T ( P T ) ~ ~ to the Escherichia coli SSB protein as a function of NaCl and MgC12 concentration (25 OC, pH 8.1) by monitoring the quenching of the intrinsic protein fluorescence. We find two binding sites for ~ T ( P T ) ~ ~ per single strand binding (SSB) protein tetramer, with each site possessing widely different affinities depending on ...

From the last line Gaines and Davidson (I9~3) derived the formula, F C M = M (.4q-.I5 f) or F C M = . 4 M-+-I5 F, in which FCM is milk energy in terms of pounds of natural whole cows' milk of 4 percent fat content, M is milk in pounds and F is milk fat in pounds. Recently, Bonnier, Hansson and Jarl (I946) report that the regression of milk energy per unit milk on fat percentage is not linear an...

Tetrodotoxin, a toxic principle of puffer fish poisoning, is one of the most famous marine natural products because of the complex structure having many functional groups and its potent biological activity leading to death. Since the structure elucidation in 1964, this toxin has been recognized as a formidable target molecule for total synthesis. We have recently achieved the first asymmetric t...

Can temporary initial input cost advantages have a long-run impact on the spatial distribution of production and trade? I study this question in the context of the international shipbuilding industry during the transition from wood to metal ship production (1850-1912). Input price advantages gave Britain an early lead in metal shipbuilding, while the U.S. and Canada specialized in wood ship pro...
