WHY CAN HUNTER-GATHERER GROUPS BE ORGANIZED SIMLARLY FOR RESOURCE PROCUREMENT, BUT THEIR KINSHIP TERMINOLOGIES ARE STRIKINGLY DISSIMILAR: A CHALLENGE FOR FUTURE CROSS-CULTURAL RESEARCH

Cross-cultural research involves explanatory arguments framed at the meta-level of a cohort of societies, each with its own historical development as an internally structured and organized system. Historically, cross-cultural research on hunter-gatherer groups initially was in accord with the general anthropological interest in determining the ideational basis for differences in systems of social organization, but more recent work has shifted emphasis to the phenomenal level of factors affecting the mode of adaptation to an external environment. This has left a major lacuna in our understanding of the reasons for cross-cultural differences among ideational systems such as kinship terminologies in hunter-gatherer societies. I address this lacuna in this article through cross-cultural comparison of hunter-gatherer kinship terminologies at an ideational, qualitative level. The means for so doing is first worked out using the kinship terminology of the Hadza, an East African hunter-gather group. Next, comparison of the Hadza and their kinship terminology with two other hunter-gatherer groups prominent in the anthropological literature, along with their kinship terminologies, makes evident a major disjunction between, on the one hand, the similarity of hunter-gatherer societies at the phenomenal level of activities such as food procurement and, on the other hand, striking differences among the same groups at the ideational level of the structural organization of their kinship terminologies. The reason for the striking differences between the ideational and the phenomenal levels is not immediately evident and remains a topic to be addressed in future cross-cultural research

Silent emergency alarm system for schools and the like

An emergency alert system is described. In a school each classroom (or other area) is instrumented with a hidden microphone and receiver tuned to a non-audible frequency. The receivers' outputs are connected to a central display unit in the school's administrative office. Each instructor is provided with a small concealable transmitter which, when hand activated by the instructor upon the occurrance of any emergency, generates a non-audible signal at the receiver's tuned frequency

Tool for use in lifting pin supported objects

A tool for use in lifting a pin-supported, electronic package mounted in juxtaposition with the surface of an electronic circuit board is described. The tool is configured to be received beneath a pin-supported package and is characterized by a manually operable linkage, including an elongated, rigid link is supported for axial reciprocation and a pivotal link pinned to the body and supported for oscillation induced in response to axial motion imparted to the rigid link. A lifting plate is pivotally coupled to the distal end of the pivotal link so that oscillatory motion imparted to the pivotal link serves to move the plate vertically for elevating the plate into lifting engagement with the electronic package positioned thereabove

BACK TO KINSHIP III: A GENERAL INTRODUCTION

Back to Kinship III is the third Special Issue of the e-journal, Structure and Dynamics sponsored by the group, Kinship Circle. Each issue is dedicated to current kinship research.There are 5 articles in this Special Issue, covering a wide range of kinship research questions and topics The first two articles, by William Young and Warren Shapiro, respectively, employ ethnographic evidence as the reason for revising previous kinship ideas. The next two articles, by Robert Parkin and Dwight Read, respectively, focus on kinship terminology and revisit theoretical issues. The last article, by Alain Matthey de l’Etang, discusses theorizing by Dwight Read challenging the “received view” of kin terms being derived through a genealogical framework and proposing, in its place, that kin terms are structurally organized through a generative logic for the terminolog

Vorticity imbalance and stability in relation to convection

A complete synoptic-scale vorticity budget was related to convection storm development in the eastern two-thirds of the United States. The 3-h sounding interval permitted a study of time changes of the vorticity budget in areas of convective storms. Results of analyses revealed significant changes in values of terms in the vorticity equation at different stages of squall line development. Average budgets for all areas of convection indicate systematic imbalance in the terms in the vorticity equation. This imbalance resulted primarily from sub-grid scale processes. Potential instability in the lower troposphere was analyzed in relation to the development of convective activity. Instability was related to areas of convection; however, instability alone was inadequate for forecast purposes. Combinations of stability and terms in the vorticity equation in the form of indices succeeded in depicting areas of convection better than any one item separately

Development and verification of design methods for ducts in a space nuclear shield

A practical method for computing the effectiveness of a space nuclear shield perforated by small tubing and cavities is reported. Performed calculations use solutions for a two dimensional transport code and evaluate perturbations of that solution using last flight estimates and other kernel integration techniques. In general, perturbations are viewed as a change in source strength of scattered radiation and a change in attenuation properties of the region
