Urban development patterns in Indonesia

The author examines recent urban development in Indonesia. "Analysis of urban developments in Indonesia has been hampered in the past by weak data. Recently, the National Urban Development Strategy (NUDS) project has generated a set of improved data. This paper aims at elaborating and supplementing the NUDS study. After a discussion of definitional problems, an analysis is carried out of urban growth rates at the provincial level. Private investment is shown to be a principal determinant of urban growth rates. Other significant determinants are rural immigration and the present level of urbanisation. Private investment is shown to be strongly biased towards provinces with large urban areas. In addition, polarisation is studied at the level of individual cities. It is found that a period of rapidly increasing polarisation has come to an end during the last decade."     

The CEO as organizational architect: an interview with Xerox's Paul Allaire. Interview by Robert Howard

As chairman and CEO of the Xerox Corporation, Paul Allaire leads a company that is a microcosm of the changes transforming American business. With the introduction of the first plain-paper copier in 1959, Xerox invented a new industry and launched itself on a decade of spectacular growth. But easy growth led Xerox to neglect the fundamentals of its core business, leaving the company vulnerable to low-cost Japanese competition. Starting in the mid-1980s, Xerox embarked on a long-term effort to regain its dominant position in world copier markets and to create a new platform for future growth. Thanks to the company's Leadership through Quality program, Xerox became the first major U.S. company to win back market share from the Japanese. Allaire describes his efforts to take Xerox's corporate transformation to a new level. Since becoming CEO in 1990, he has repositioned Xerox as "the document company" at the intersection of the worlds of paper-based and electronic information. And he has guided the company through a fundamental redesign of what he calls the "organizational architecture" of Xerox's document processing business. Few CEOs have approached the process of organizational redesign as systematically and methodically as Allaire has. He has created a new corporate structure that balances independent business divisions with integrated R&D and customer operations organizations. He has redefined managerial roles and responsibilities, changed the way managers are selected and compensated, and renewed the company's senior management ranks. And he has articulated the new values and behaviors Xerox managers will need to thrive in a more competitive and fast-changing business environment.     

Integration in the mortgage market

The deregulatory trend and advances in technology during the 1980s removed many restrictions on the ability of U.S. depository financial institutions to obtain and redistribute funds across diverse geographical markets. This pervasive deregulation and innovation should have increased the degree of integration between different geographical financial markets. Yet there is little empirical evidence available on the validity of this expectation. It is important to provide such evidence since much of the U.S. depository institution regulatory policy is predicated on the assumption of highly localized, segmented financial markets. Considering alternative breakpoints at 1980 (DIDMCA) and at 1982 (Garn-St Germain), the current study tests the hypothesis that the degree of geographical financial integration after this period exceeded that prior to this period. Mortgage markets are focused on due to their historical importance in the regulation of funds flows. The study finds a significant increase in the mean contemporaneous correlation among FHLB districts' mortagage rate residuals in a vector-autoregressive system between two test periods. Further analysis shows that the distance between FHLB districts' headquarters and their respective pairwise interdistrict correlation coefficients are negatively related in the prior period but not significantly related in the later period. Economic booms and busts alternated among the districts over the two sample periods in a manner consistent with the reallocation of capital among more integrated financial markets. Individual districts' mortgage rates have been more sensitive to variations in national credit market conditions since deregulation was legally recognized by DIDMCA in 1980. Thus, the collective empirical evidence found in this study indicates that mortgage markets have responded to deregulation and marked technological advances by moving toward a national, highly integrated market. Regulators' preoccupation with highly localized, segmented markets must consequently be reexamined.     

Couple's literacy level and acceptance of family planning methods: Lorenz curve analysis

The authors study the acceptance of family planning methods according to the level of couple's literacy in 14 states in India during 1986-87, using the Lorenz curve. The Gini Concentration Ratio and Index of Dissimilarity were calculated by level of couple's literacy for vasectomy, tubectomy, IUD, and all method combined. Firstly, analysis found literates to have accepted vasectomy and IUD more than tubectomy. Secondly, among the 3 methods, a high Gini Concentration Ratio was found for vasectomy when the wife was literate. Moreover, when the wife was literate, the Gini Concentration Ratio of IUD acceptance was higher than the acceptance of IUD by the wife whose husband was literate. Thirdly, the same trend was observed when the husband was illiterate. It is therefore clear that the level of a woman's literacy is a key factor in securing the acceptance of male or female methods of family planning. Planners should therefore concentrate on literacy programs for females independently of their age. Increasing the level of female literacy may ultimately help improve the understanding of family planning methods, while these women may also motivate their husbands to undergo vasectomy which will ultimately foster the success of the family planning program.     

Operational Research and the environment

The discipline of Operational Research (OR) is primarily concerned with improving the effectiveness and efficiency of decision processes. These processes take place everywhere in society: industry, banking, agriculture, government, politics. Frequent use of mathematical optimization models is typical of OR. Since the early '80s these models are increasingly packaged in a user-friendly way, as Decision Support Systems. In the following we will illustrate how OR can be used to describe and solve a number of environmental problems.     

The relationship between wellness participation and health care benefit utilization

To examine the relationship between participation in a wellness program and the amount of absenteeism and medical claims, seven years of retrospective absenteeism and medical claims records were collected for 207 employees (pre- and postwellness intervention) and entered into a database. A proportional stratified random sample of workers by wellness participation was selected. While there was no significant change in the amount of sick leave taken over time, a log transformation revealed a significant increase in the dollar amount of medical claims over time, particularly for the middle-aged group of employees. This confirms that wellness intervention slowed the rate of increasing claims among middle-aged participants after just three years of wellness intervention.     

Creating a global health care company

Global pharmaceutical mergers have spread the huge costs of research and enabled companies to sell their products in countries where they previously lacked a presence. Here's how the Beecham-SmithKline Beckman marriage was developed to propel the organization into a position as a worldwide player in the drug industry.
