Indigenous Time,Colonial History: Sami Conceptions of Time and Ancestry and the Role of Relics in Cultural Reproduction

The role of the past in prehistoric societies is a frequently occurring topic in recent archaeological literature. It is proposed that prehistoric societies were concerned with the construction of an ancient past, and that relics were actively used as mnemonic devices in recalling the past. This paper comments on the significance of historicity in cultural reproduction on the basis of indigenous Sami conceptions of time and ancestry. It is a personal reflection from an archaeologist's point of view. The indigenous Sami concept of time, life and death implies that distances in the past were not ascribed any significant value and that there was no chronological or genealogical scale against which events in the past were measured. It is argued that relics were not ascribed a discursive value, and that they were not used as mnemonic devices in recalling an ancient past. By the example of Sami conceptions of time and ancestry, the author advocates great caution in promoting relics as carriers of collective memories in ancient societies.     

A Mississippian Mace at Iroquoia's Southern Door

Abstract

This paper documents a Mississippian chipped stone mace, found by Lyle Edger, an amateur collector, in an agricultural field in Nichols, NY, along the Susquehanna River. This crown-form mace is made out of Dover chert and was probably produced by Mississippian people who lived in Middle Tennessee, circa A.D. 1200–1400. We argue that the Nichols Mace could have been acquired by Iroquoian people as the result of either a gift or diplomatic negotiations. We conclude that the meanings the mace held for Iroquoian people were likely tied to how they acquired it.     

SIMPLE EXPRESSION OF THE DYNAMIC STIFFNESS OF GROUPED PILES IN SWAY MOTION

A simplified expression is derived for the dynamic stiffness of grouped piles subjected to lateral loading. A computer program, based on the Thin Layered Element Method, is used for this purpose. The results of the program are compared with rigorous solutions. The simplified expression of the dynamic stiffness of grouped piles, where the mass, damping and stiffness parameters are frequency invariant, will be particularly useful for an equivalent linear analysis of the interaction between nonlinear soil and grouped piles in real time.     

SHAKING TABLE DYNAMICS: RESULTS FROM A TEST-ANALYSIS COMPARISON STUDY

This paper presents the results of a comprehensive comparison study between the analytically predicted and experimentally identified dynamics of the shaking table system built recently in the Structural Engineering Laboratory at Rice University in Houston, Texas. The primary objectives of the research presented here are two-fold: (1) to shed light into the dynamic performance of asmall-tc-medium size, uni-axial, servo-hydraulic, displacement-controlled shaking table system, and (2) to validate a linearised dynamic model of the system (in the form of the total shaking table transfer function) developed earlier by the authors from basic principles. The analytical model incorporates the inherent dynamic characteristics of the various components of the shaking table system (i.e. controller, servovalve, actuator, test specimen, and reaction mass) and their dynamic interaction.

The test-analysis correlation study performed over a wide range of operating and payload conditions provides useful information on the sensitivity of the shaking table transfer function to control gain parameters and how it can be used to tune the shaking table controller for optimum performance under various payload conditions. The good test-analysis correlation results obtained validate the analytical shaking table model, show its robustness, and provide keen insight into the underlying coupled dynamics of a shaking table system. In order to achieve this good test-analysis correlation, it was crucial to include a time delay in the analytical model of the shaking table system (innovative feature of the model to account for the time lag in the response of the servovalve-actuator system). The expected significant dynamic interaction between payload and shaking table is also confirmed by this study.

近代旅美华侨华人与中美文化的双向交流

鸦片战争强制性地拉开了中西文化交流的序幕。1848年以后,随着北美至中国航线的开通,一部分居住在珠江三角洲的广东人在多种原因的驱使下,远渡重洋来到北美。在美国西部形成了一个又一个的华侨华人社区,使中国的古老文明渐次播散到美国西部各州。随着北美华侨华人的不断扩展,不同类型的华侨华人在不同的领域里(商业、建筑、科技教育、宗教伦理、风俗习惯等许多文化领域里)对中华传统文化进行了被动和主动传播。被动的传播形成了美国多元文化的文化飞地,主动的传播使中国传统文化在美国文化的大熔炉里形成了一种鲜明的、交叉式的边缘文化。文化的传播是一个双向互动的过程。随着大批旅美华侨华人陆续返回故乡,他们也把西方文明带回侨乡。它们与本土文化发生碰撞、冲突、融合,从而在珠江三角洲一带的侨乡形成了新鲜的、西方式的边缘文化。     

Displacement Ductility Limits for Pile Foundations in Cohesionless Soils

The displacement ductility limit for seismic design of concrete piles is determined for the range of cohesionless soils expected in practice. The curvature ductility capacity associated with specified performance limit states, namely, the “serviceability” and “damage-control” limits, is determined based on the current provisions for confining steel. An analytical model is applied to assess the displacement ductility factor at the specified curvature ductility level. The investigated parameters include the soil stiffness, pile diameter, longitudinal reinforcement ratio, axial force level, and pile above-ground height. A set of design displacement ductility factors is recommended and verified to ensure the satisfactory seismic performance.     

Using historically informed archaeology: Seventeenth and eighteenth century Hueda/European interaction on the coast of Bénin

The period of the Atlantic slave trade between Africa and European colonies is relatively well documented compared with the historic records of many regions of precolonial Africa. However, this documentation necessarily presents a perspective distilled through European eyes. This paper suggests a methodology influenced byAnnales history for critically analyzing documentary sources in conjunction with a critical interpretation of archaeological remains. Archaeological evidence from recent excavations at the site of Savi, capital of the Hueda kingdom, is contrasted with documentary evidence, facilitating an interpretation of motivations guiding Hueda interaction with European traders and structuring their spatial relationship.     

Prehistoric exchange and interaction in southeastern southern africa: Marine shells and ostrich eggshell

The spatiotemporal distribution of seashells and ostrich eggshell in the Later Stone Age of southeastern southern Africa is used to infer several areas of social interaction. The inferred patterns are supported by comparisons with preferences for lithic raw materials and the distribution of bifacial stone arrows. Plusiers zones de l'interaction sociale sont déduites des distributions chronologiques et spatiales de la coquillage et de la coquille de'autruche de l'Age de la Pierre Récent au sud- est de l'Afrique australe. Ces distributions sont soutenues des préférences pour des matières premières lithiques et de la distribution des flèches bifaciales de la pierre. Provincial names and boundaries are as given on May 1, 1994     

Diagenesis and elemental geochemistry under varying reservoir oil saturation in the Junggar Basin of NW China: implication for differentiating hydrocarbon‐bearing horizons

In this paper, we attempt to differentiate hydrocarbon‐bearing reservoir horizons of the Junggar Basin of NW China based on the characteristics of diagenesis and associated elemental geochemistry. Reservoirs at this site have varying levels of oil saturation that correlate with the degree of dissolution in minerals (e.g., calcite and feldspar). Four different horizons with varying diagenetic mineral assemblages were observed, including (i) kaolinite‐rich, oil‐dominated horizons, (ii) kaolinite–pyrite–hematite‐rich, oil–water‐dominated horizons, (iii) siderite–chlorite‐rich, water‐dominated horizons, and (iv) chlorite‐rich horizons with negligible hydrocarbon production. The mean MnO content of the representative diagenetic mineral (e.g., calcite) in each of the above horizons is >2.5, 2.0–2.5, 1.5–2.0, and <1.0 wt%, respectively. We propose that the above methodology can be used for the identification of reservoir hydrocarbon‐bearing horizons. We argue that the indicators presented here can be applied in oil exploration across the Junggar Basin.
