邢台南小汪周代遗址西周遗存的发掘

<正> 南小汪遗址位于邢台市市区西北部。这是一处范围很大的周代遗址,经初步调查,大致在今京广铁路以西,小黄河以北,达活泉以南,因南小汪村位于遗址北部而得名(图一)。 南小汪遗址南与曹演庄、南大郭等殷商遗址相连,西北与南大汪战国墓区相望。五十年代调查试掘的西关外西周遗址,实际上即是南小汪遗址的一部分。近年来,邢台市市政建设发展迅速,南小汪遗址绝大部分已被建筑所压。在施工过程中,时有周代遗物出土,如在郭守敬大街左右两侧的市一中附近、中华路宿舍区、团结路南侧等地,均曾发现大量的周代陶器鬲、盆、豆、罐等,有的地方还发现马坑和小型墓葬等。这些都表明南小汪遗址是一处规模较大、埋藏丰富的周代遗址。

When Studies Collide*

Environmental epidemiology increasingly is being used as a foundation for environmental health policy. Since environmental epidemiologic studies have increased dramatically in number, approaches are needed to interpret them. Two approaches used in epidemiology are rules of evidence and meta-analysis. Rules of evidence pertain to the consistency, strength, uniqueness, and medical basis of the relationship between disease and risk factors such as chemicals. Meta-analysis is a systematic and rigorous approach to comparing studies and understanding their heterogeneity. Dioxins, benzene, and formaldehyde are three chemicals that are at the forefront of health policy debates. These chemicals illustrate some of the conditions under which researchers are drawn or are not drawn to approaches to compare studies. A meta-analysis was not conducted for dioxins or benzene, but was conducted for formaldehyde. Rather than addressing study comparisons, epidemiologic studies of dioxins are focusing on expanding the number of health effects studied and obtaining greater specificity for exposures, whereas studies of benzene are focusing on effects at low dose exposures. In the case of formaldehyde, meta-analysis has strengthened the evidence for some health effects beyond what individual studies could provide. Thus, whether rules of evidence and meta-analysis approaches to synthesizing information are used can depend upon where the debates are focused.

Some New Methods of Topologic Classification of Channel Networks

Some new methods for the topologic classification of channel networks are proposed. These methods are all based on the concept of topologic path length, or number of links from the network outlet to a junction or source. Two parameters, the total path length (sum of all path lengths) and the diameter (largest path length) are shown to be useful in network analysis. Some advantages of these parameters are that they are easy to measure, have straightforward topologic interpretations, and are closely related to important geometric measures. Moreover, they are capable of explaining various empirical geomorphic “laws,” such as the 0.6 power relation between mainstream length and area.

The environmental aspects of reterritorialization: Environmental facets of Israeli–Arab agreements

Reterritorialization processes change the demarcation and function of boundaries and create new realms of authority. As political and natural boundaries rarely coincide, such processes increase the discrepancies between spheres of control and natural systems, thereby increasing the externalization of environmental problems and raising the transaction costs of addressing them. The actual environmental implications of reterritorialization processes are a function of both the direct barrier effects of boundaries and the role of boundaries as separators between management regimes. In contrast to environmental agreements, which focus on a very limited set of issues, agreements that are negotiated as part of reterritorialization processes may address a wide array of environmental issues. This paper asks which environmental issues are addressed in such agreements, and what are the factors that affect the range of issues that are addressed, and the extent to which they are addressed. To this end, the three agreements signed between Israel and her neighbors, Egypt, Jordan and the Palestinians, are analyzed. This analysis shows that the issues that tend to be addressed are either high profile issues (such as water in the Middle East) or those that do not impinge on ‘high politics’. This finding suggests that there is a latent contradiction between political and environmental considerations in negotiating such agreements. While management regime effects are, arguably, more important than direct barrier effects from an environmental perspective, they are largely viewed as internal issues, and hence they are not likely to be addressed in such agreements.     

Iron Age Ferrous Hammerheads from Britain

There are more than thirty iron hammerheads known from the pre-Roman Iron Age in Britain, the majority of which are assigned to the first centuries BC and AD. They include specialised tools, such as set hammers and a swage sledge-hammer which are blacksmiths' tools. The hand-hammers are more numerous and many of these are probably also metalworkers' tools. Fourteen have been examined by metallography showing that at least ten are quench hardened at one or both faces and some may have been tempered.     

Extraction of Hierarchical Surface Networks from Bilinear Surface Patches

Surface networks capture the topological relations between passes of a continuous surface, the paths of steepest descent and ascent starting at the passes, and the pits and peaks where the steepest paths end. Surface networks represent the topology of surfaces in a compressed form and allow fast investigation of the surfaces' convex and concave shapes. They are applied, for instance, for enhancing algorithms for surface analysis, for surface model simplification, and for surfaces visualization. Furthermore, they are themselves subjects of analysis as they are closely coupled to the intrinsic geometrical concepts and rules of continuous surfaces.
This article extends the topology of surface networks in four ways: (i) objects at the edge of the surface model are introduced; (ii) intersections between valley and ridge lines are found to be possible, and such intersections are incorporated into the topology; (iii) horizontal areas may represent passes, pits, or peaks, and therefore must be detected and explicitly incorporated; and (iv) valley and ridge line hierarchies are recognized as inherent components of the surface network. They are extracted and explicitly represented.
To ensure consistency and completeness of the surface network, a zero-order continuous surface is specified from the raster data prior to the extraction. This article presents a method to represent and derive valley and ridge line hierarchies. The results are illustrated with two examples. The extracted networks are found to be consistent and complete. However, the extraction method tends to produce spurious pits, peaks, and passes, which form a drawback if the surface data are affected by noise.

Knowledge Externalities and Knowledge Spillovers in Social Networks: The Case of Izmir Metalwork Industrial District

Social networks are the networks based on relationships between social entities. Since social interactions are directly associated with externalities, these relationships are assumed to create opportunities for the network members by providing especially knowledge flows. In this context, the main objective of this study is to show the role of knowledge externalities in social networks. By following this aim, some theoretical derivations are delivered and survey results in a small-world network are explained. Consequently, after a brief introduction, the first section of this study consists of a theoretical model derived by including knowledge externalities in social networks. In the second section, a survey applied in Izmir Metalwork Industrial District is explained. Finally, in the third section, survey results are presented and then conclusions and discussions for further research are revealed. Contributions of this study to the related literature are three-fold. Firstly, knowledge externalities are added to the models of knowledge flows in social networks explicitly. Secondly, a questionnaire trying to measure knowledge spillovers and knowledge externalities separately is introduced and applied for the first time in the literature. Finally, such an analysis is the first for Izmir which is the third metropolitan city of Turkey.     

A TECHNIQUE FOR CLASSIFYING URBAN PLACES IN TERMS OF DEVELOPMENT REQUISITES (with particular reference to Smolensk Oblast)

On the basis of a number of socio-economic and physical requisites, the prospects of future development are examined for all 28 urban places of Smolensk Oblast as of early 1973. The requisites are the economic-geographic (transport) situation, availability of water resources, labor resources, economic base, industrial terrain and housing. The urban places are assigned point scales combining these factors and are assigned to three categories (with very favorable, favorable and unfavorable prospects of development). The allocation of places to particular development classes is then tested statistically by association with two additional variables: population size and functional characteristics, and the corrections introduced by the procedure are analyzed. The prospects for further development are found to be most favorable for the six largest towns—Smolensk, Roslavl', Vyaz'ma, Safonovo, Yartsevo and Gagarin. (The study was completed before the founding in 1973–74 of two new urban places that are associated with major power stations under construction and are thus endowed with growth prospects: Desnogorsk, on the site of the Smolensk nuclear power station, and Ozernyy, on the site of the Smolensk peat-fired power station.)     

PRICE UNCERTAINTY,FACTOR SUBSTITUTION,AND THE LOCATIONAL BIAS OF BUSINESS TAXES*

Consideration of the integrated production-location problem is extended to include several types of business taxes. Many of these taxes are technologically and spatially neutral under certainty, but are shown to be nonneutral when factor prices are stochastic and the firm is risk averse, even when the tax is spatially uniform. Consequently, even a nationally uniform tax can have regional biases and can encourage migration of plants. When factor prices are uncertain, the effects of taxes on output rates, input ratios, and plant location vary with the form of the tax imposed as well as the amount to be paid. Income taxes involve the taxing authority in sharing the risk with the firm and are shown to promote risk taking by the firm and induce the expansion of output. Locational incentives which are mutually beneficial to firms and the government are presented.

Poor people on the move: county-to-county migration and the spatial concentration of poverty

Poverty rates in high-poverty and low-poverty rural counties, and, thus, the spatial concentration of poverty, are affected by poverty-specific differences in in-migration and out-migration patterns. These patterns are investigated using 1985–90 county-to-county migration data from the decennial census. Effects on poverty rates of four migration flows (in- and out-migration of poor, in- and out-migration of nonpoor) are quantified, and their impacts on spatial concentration of poverty are assessed. The effect of selected county characteristics on the migration of the poor and nonpoor in nonmetro counties are estimated. The poor are as mobile as the nonpoor, and the migration patterns of both poor and nonpoor generally maintain and reinforce the pre-existing spatial concentration of poverty.

THE ROMAN DENARIUS UNDER THE JULIO-CLAUDIAN EMPERORS: MINTS, METALLURGY AND TECHNOLOGY

Summary. The results of the chemical analysis of 78 silver denarii issued by the Julio-Claudian emperors are presented and interpreted against the available numismatic, archaeological and historical information. Earlier surface analyses are found to be incorrect, especially for the coinage of Nero, and the reasons for this are investigated. The new elemental data are augmented by a subset of coins being subjected to lead isotope analysis and the results of this are found to complement these data in unexpected ways.     

Transcending the fixity of jurisdictional scale

In this commentary I argue that the case study of the Hanford Reservation illustrates that local interests are not coterminous with the scale of local government. Hanford is an example of a decentralized land-use decision-making process, whereby multiple government jurisdictions and diverse interest groups are involved in the negotiations. While the governments are fixed by scale, the other actors are not, and their interests are fluid across scales. Interest groups are most concerned with land-use outcomes, whereas Morrill presents local governments as most interested in their authority over land use. Analysis of land-use conflicts, therefore, must involve examination of both scale-bounded government autonomy as well as the power struggles and cross-scale alliances of the multiple interests and social identities expressing concern about the outcome.
