OBNOXIOUS FACILITY LOCATION IN THE INTERIOR OF A PLANAR NETWORK*

ABSTRACT. The problem of locating a point that is as far as possible from arcs and nodes of a network is investigated. Each arc or node may have a different multiplicative factor (weight) for its distance. A graphical solution approach, as well as a computational algorithm, is presented.     

Memories of Kings of Israel and Judah within the Mnemonic Landscape of the Literati of the Late Persian/Early Hellenistic Period: Exploratory Considerations

This article explores, from a perspective informed by Social Memory studies, memories of kings of Judah (/Israel) in three different corpora (the Deuteronomistic Historical Collection, the Prophetic Book Collection and Chronicles). It draws attention to the interdependence between memories of kings and other characters populating the world of memory evoked by each of these corpora and explores the ways in which the worlds of memory evoked by each of them interacted, informed and balanced each other within what we may call the “comprehensive mnemonic system” of the literati. The article sheds light on generative grammars governing systems of preferences and dis-preferences for certain types of memories of kings in each of the corpora and across them, and at times, even across cultures, and highlights that the world of memory of the Yehudite literati of the late Persian/early Hellenistic period was shaped by a consistency of inconsistency, and an overall coherence manifested through a seeming lack thereof that served well the social reproduction of the group.     

Phytolith-rich layers from the Late Bronze and Iron Ages at Tel Dor (Israel): mode of formation and archaeological significance

The presence of many phytolith-rich layers in late Bronze and Iron Age deposits at Tel Dor, Israel, are indicative of specific locations where plants were concentrated. Detailed studies of six of these phytolith-rich layers and associated sediments from Tel Dor show that the phytoliths were derived mainly from wild and domestic grasses. The most common domestic grass was the cereal Triticum aestivum (bread wheat). Three of these layers have a microlaminated microstructure, associated dung spherulites and phosphate nodules; characteristics that all point to the phytolith-rich layers having formed from dung in animal enclosures. In two of the layers, the microlaminated structure is absent while dung spherulites and phosphate nodules are present, suggesting that these too originate from dung that was not deposited in an enclosure. The sixth layer is microlaminated but does not contain spherulites. We thus cannot suggest a parsimonious explanation of its observed properties. Concentrations of burnt phytoliths are present in three locations, implying that dung was either burnt in situ or the ashes from burnt dung were redeposited. The transformation of dung accumulations into phytolith-rich layers involves a loss of organic material and hence a significant reduction in sediment volume, which is clearly apparent in the stratigraphy of some of the locations examined. The volume reduction can be observed in the macrostratigraphy and has important implications with regard to macrostratigraphic interpretation. The presence of abundant phytolith-rich layers on the tell has significant implications for the concept of ‘urbanism’ during these periods.     

The construction of an ideological curriculum: The study of Emunah in the Har Hamor Yeshiva

Beginning in 1997, the Har Hamor Yeshiva, a leading Jerusalem-based institute for Torah learning, has become the center of a unique stream of thought in religious Zionist philosophy. This article examines how religious Zionist yeshivas have developed an educational curriculum that translates theological beliefs and values into political action. The article seeks to evaluate to what extent this ideology and curriculum will be able to survive in a political reality in which the rift between religious and secular Zionism is constantly increasing.     

RECENT DEMOGRAPHIC AND MIGRATORY TRENDS AMONG SOVIET JEWS: IMPLICATIONS FOR POLICY

A prominent authority on the Jewish population of the former USSR focuses on demographic trends and migration behavior (both within the former USSR and abroad), while also addressing the effect of Soviet state policy toward the Jewish population. Among the factors whose effects on population dynamics are examined, emphasis is placed on the Jewish population's concentration in large urban areas, the effects of emigration on age structure of the remaining population, self-identification as a method in census enumeration, ethnic intermarriage and family characteristics, and the outlook and prospects for emigres in Israel and the United States.     

A Note on Applying the Gravity Rule to the Airline Hub Problem

In this note we propose a new model for the airline hub selection problem. Passengers use a hub on the way to their destination. We apply the objective of minimizing the total miles traveled by passengers. This formulation can be used as the basis for other objectives also.
