Keeping the high-tech region open and dynamic: the organizational networks of Taiwan's integrated circuit industry

This paper aims to bridge the literatures of industrial districts and organizational networks by studying the development of organizational relationships in Taiwan's integrated circuit (IC) industry. Firms of the IC industry in Taiwan are highly concentrated in the Hsinchu Science-based Industrial Park (HSIP). They not only have contributed the most to the combined sales for the HSIP compared to other industries for half a decade, but also have made Taiwan the country with the fourth-largest IC industry in the world today. Along with the creation and maintenance of global competitiveness in this industry, the means of developing organizational relationships and geographical linkages are examined in this paper. The empirical findings are based on analysis of data regarding the organizational connections for Taiwan's IC industry during 1976 to 1996, collected at the individual firm level. It is found that a concurrent process of intensifying the internal as well as external linkages has occurred in the HSIP, a young high-tech region. It indicates that not only is the ``regional advantage' sufficiently sustained, but also the global industrial networks are continuously expanded to maintain the openness and dynamics of the region.     

广州飞龙世界游乐城关闭的原因与启示

广州番禺“飞龙世界游乐城”是广州市首座主题公园，在1995年元月开业前后，各种新闻媒体普作过大量宣传，实际景点建设、经营运作声势浩大，一度名扬粤港澳，但在营业4年后，却被广州番禺法院封闭停业了。文中从旅游科学和旅游业实践的角度，通过实地调查研究，认为其失败的主要原因是：（1）景点建设背离主题，贪大求全；（2）市场定位盲目乐观，大量设施空置；（3）经营管理上未能扬长避短，蛇系列产品未能适销对路进入园国际市场；（4）投资机制上靠贷款建设，经营严重亏损，并从中得到几点启迪，供今后创办主题公园借鉴。     

Recent large-magnitude floods and their impact on valley-floor environments of northeastern Yellowstone

The Lamar River watershed of northeastern Yellowstone contains some of the most diverse and important habitat in the national park. Broad glacial valley floors feature grassland winter range for ungulates, riparian vegetation that provides food and cover for a variety of species, and alluvial channels that are requisite habitat for native fish. Rapid Neogene uplift and Quaternary climatic change have created a dynamic modern environment in which catastrophic processes exert a major influence on riverine–riparian ecosystems. Uplift and glacial erosion have generated high local relief and extensive cliffs of friable volcaniclastic bedrock. As a result, steep tributary basins produce voluminous runoff and sediment during intense precipitation and rapid snowmelt. Recent major floods on trunk streams deposited extensive overbank gravels that replaced loamy soils on flood plains and allowed conifers to colonize valley-floor meadows. Tree-ring dating identifies major floods in 1918, ca. 1873, and possibly ca. 1790. In 1996 and 1997, discharge during snowmelt runoff on Soda Butte Creek approached the 100-year flood estimated by regional techniques, with substantial local bank erosion and channel widening. Indirect estimates show that peak discharges in 1918 were approximately three times greater than in 1996, with similar duration and much greater flood plain impact. Nonetheless, 1918 peak discharge reconstructions fall well within the range of maximum recorded discharges in relation to basin area in the upper Yellowstone region. The 1873 and 1918 floods produced lasting impacts on the channel form and flood plain of Soda Butte Creek. Channels may still be locally enlarged from flood erosion, and net downcutting has occurred in some reaches, leaving the pre-1790 flood plain abandoned as a terrace. Gravelly overbank deposits raise flood-plain surfaces above levels of frequent inundation and are well drained, therefore flood-plain soils are drier. Noncohesive gravels also reduce bank stability and may have persistent effects on channel form. Overall, floods are part of a suite of catastrophic geomorphic processes that exert a very strong influence on landscape patterns and valley-floor ecosystems in northeastern Yellowstone.     

The role of resource recycling

Resource recycling reduces the amount of waste discharged into the global environment. The waste reduction achieved by thorough recycling is substantial. Recycling is thus an inseparable part of global environmental protection.We human beings have used mineral resources since the birth of our species. The quantities and increasingly complex forms in which mineral resources have been used at different times in our prehistory and history serve as indices of civilization's advancement. But on the eve of the 21st century, environmental pollution and global warming stemming from spiraling resource and energy consumption pose serious dilemmas for humanity. The rapidity with which our resource consumption has increased approximates exponential growth.The worsening condition of the earth's environment because of massive resource and energy consumption is the result of activity at many stages of production, from the mining of mineral resources to the manufacture of finished products; the culmination of the process is the disposal of products as waste after their use. As we shall see from examples given in this paper, efforts are being made to solve this problem through recycling; but in many areas the problems remain incompletely solved or unsolved altogether.

Industrial sulfur demand: Analysis and prospect

Weak growth in industrial (nonagricultural) U.S. sulfur demand has slowed the growth of total sulfur demand. Evaluating prospects for trend reversal is hampered by inadequate detailed data published by industry, and the lack of an easily measured demand component that reliably depicts total demand. In this article, I try to overcome this data deficiency by constructing an industry-by-industry breakdown of published data on total industrial sulfur consumption. Industrial sulfur consumptions were estimated from data on consuming industry activity, characteristics of relevant industrial processes, and analyses of the conditions affecting choice among alternative industrial processes. Subjective projections of the industry detail data are presented.In addition to cyclical factors, past declines in industrial sulfur demand were due to replacement of sulfur-using industrial processes with alternative processes that use less or no sulfur to achieve production cost economies. In some, but not all, cases, changeovers of process were in response to impositions of environmental-related requirements. The demand for industrial sulfur has good prospects for positive growth as shrinkage of some markets reaches natural limits and total market growth comes increasingly to be dominated by markets with positive growth prospects. Positive growth has been generated by environmentally related regulation in several markets, such as petroleum alkylation and copper production.

Cavernous weathering in the Capitol Reef Desert,Utah

Tafoni and honeycomb weathering are abundant in sandstones at Capitol Reef National Park. Cavities are particularly common in talus blocks resting on alkali-rich soil, in vertical walls of desert washes, and in sandstones containing calcareous cement. Chemical analyses, X-ray diffraction data, and field observations suggest that salt weathering is the most important cause of disintegration, but dissolution of calcite cement also occurs in calcareous sandstones. Cavernous weathering at Capitol Reef produces cavities similar in appearance to features found in arkose outcrops along the coast of northwest Washington, even though the environmental conditions at these two locations are very different.     

Coincidence of cadmium and antibiotic resistance in New York Bight apex benthic microorganisms

Microorganisms resistant to 1–500 ppm cadmium were isolated over an 11 month period from sediments at the sewage sludge, dredge spoils and industrial acid waste disposal sites, as well as at an estuarine outflow to the New York Bight apex. Tests for antibiotic resistance in these isolates revealed that 94% of the isolates were resistant to one or more antibiotics and that 91% of the original isolates could be characterized by multiple drug resistance. Different selective pressures may account for the various genera and antimicrobial resistance patterns observed. The possibility of extrachromosomal linkage of cadmium and streptomycin resistance is discussed.
