The senior author has elsewhere argued [8] that foreign exchange earned by the export of West Pakistan-manufactured goods has a high domestic cost. Much the same contention has been advanced by Hecox [7], Islam [9] and MacEwan [11]. In these papers the relationship between costs and earnings is usually based on fairly abstract assumptions. The purpose of this note is to reduce the calculations to a "plain man" level. Specifically, we try to calculate how many rupees of indigenous resources are expended to earn each extra rupee of foreign exchange which is received from exporting cotton textiles and leather goods rather than their primary ingredients, namely raw cotton and hides and skins i. Since this note was written, the Board of Economic Inquiry, Lahore, at the request of the West Pakistan Planning and Development Department, has undertaken a wider study applying the same general approach used here.

The incompleteness of Victorian census returns of marriage and birth records for England and Wales, and the high costs of using civil and church records, have greatly restricted research into the timing and character of the decline in marital fertility in the second half of the 19th century. This article argues that, in spite of these limitations, the census returns provide enough data to allow the well-known the 'Own-children method of fertility estimation', when used within Bongaarts' framework for analysing the proximate determinants of fertility, to derive estimates of total and age-specific marital fertility for women 15 to 49 years of age. It uses data from the census returns for the town of Rawtenstall, a small cotton textile manufacturing town in north-east Lancashire, to generate these estimates and to test their credibility against other well respected measures of marital fertility for England and Wales.

Objective: The cotton textile industry, as a competitive industry in China's international competition, is confronting new opportunities and challenges brought by the growing process of mechatronics. To further improve the traditional drive control of combing machines made in China and the automatic level of machines as a whole, some of our cotton textile enterprises have undertaken necessary technical transformations on the combing machines so as to raise the operational efficiency and production technology of domestic textile equipments. Methods: This paper focuses on the basic status and dynamic characteristics of the drive part of the domestic new comber, and analyzes the operation process of the comber and the prominent problems from the production practice. Results: The technically improved drive control system uses an industrial control computer (IPC) as the core of the system, which effectively improves the overall working efficiency of the comber, and improves the production accuracy and production efficiency. Conclusion: The combers that are textile machinery equipments with comprehensive application of machines, electricity, gases and instruments, play a vital role in enhancing product quality and production efficiency. Highly intelligent and integrated process control, real-time monitoring and accurate data acquisition and data analysis have become the mainstreams in the development of auto-control. Therefore, the commitment of high technology to transform the traditional production mode has also been an important research.
