Die Stadt Troki (54O38,5' N. Br. und 24O 56' E. L. von Greenwich) liegt auf einer Halbinsel, die im S. mit dem Lande verbunden, nach E. an den Bernardyny-See grenzt, dessen Hinterland ein grosses Seebecken bildet, das versumpft und mit verwachsenden Seen bedeckt ist; im W. grenzt die Halbinsel mit dem See Tataryszki, hinter dem sich auch ein, wenn auch weniger deutliches, Seebecken erstreckt. Beide Becken sind durch den Lauf der Isohypse von 154 m. an die topographische Karte im Masstab 1:100000 bezeichnet. Im N. grenzt die Halbinsel an den See Galwe (s. S. 3). Die Troker Halbinsel besteht zum grössten Teil aus Os, der nach NW. abbiegend, durch den See Tataryszki geht und in seinem weiteren Laufe den See Galwe (149 m. ü. d. M.) von dem höher gelegenen See Okmiany (153 rn. ü. d. M.) trennt. Nach S. geht der Os noch über die Halbinsel hinaus sich in zwei Nebenose teilend, die bald im Gelände verschwinden. Nach W. vom Kulminationspunkte des Os erstreckt sich auf der Halbinsel eine abflusslose, versumpfte Vertiefung, die den Osgraben bildet. Die Stadt Troki breitet sich im nördlichen Teil der Halbinsel aus, lange Zungen nach S. und NW. längs der hier laufenden Wege ausbreitend. In dem von mir betrachteten geographischen Gebiet der Stadt, dienen als Grenzen die Seen: Tataryszki, Galwe und Bernardyny, nach S. hingegen die Äquidistante, die in der Entfernung von 50 m. von den am weitesten zur Peripherie vorgeschobenen Wohngebäuden geführt worden ist. ...

This paper integrates elements from the theory of agency, the theory of property rights and the theory of finance to develop a theory of the ownership structure of the firm. We define the concept of agency costs, show its relationship to the "separation and control" issue, investigate the nature of the agency costs generated by the existence of debt and outside equity, demonstrate who bears these costs and why, and investigate the Pareto optimality of their existence. We also provide a new definition of the firm, and show how our analysis of the factors influencing the creation and issuance of debt and equity claims is a special case of the supply side of the completeness of markets problem.
A new method of measuring compressibility and thermal expansions of liquids has been developed, in which the liquid is enclosed in a sylphon, which is then exposed to external hydrostatic pressure, and the volume change determined from the change of length of the sylphon. This method has been applied to 18 liquids at 0°, 50°, and 95° up to a pressure of 12000 kg, or to the freezing pressure, and the results are collected into extensive tables giving the volume as a function of pressure aand temperature over this range. In the discussion it is shown that small scale differences in the volumes of various isomers persist to high· pressures, and there is no simple connection between the relative densities at atmospheric pressure and at high pressure, The compressibility falls off rapidly with rising pressure, as was found in a preceding investigation. Two liquids are found to have the abnormally low compressibility of water. Thermal expansion also drops off by a large factor with increasing pressure, but not as much as the compressibility, as was also found before. The "pressure coefficient" (δp /δt) , is not a function of volume only, as has often been supposed, and suggestions are made as to the theoretical significance of this.
In the Maizuru zone nearly whole the Triassic successions are developed. The Scythian to Aniso-Ladinian strata make a continuous sequence, in which are distinguished three faunizones, Neoschizous-"Bakevellia", Hollandites-"Danubites" and Monophyllites, corresponding to Scythian, lower Anisian and Aniso-Ladinian, respectively. Main portion of the Ladinian series is lacking in this region. The earliest Carnian or Ladino-Carnian Arakuran age is newly proposed founded on the palaeontological and stratigraphical studies on the Arakura formation. In the next Sakawan (not Carnian) Nabae group, two and probably one more, faunizones are recognizable, Palaeopharus-Lima yataensis, Tosapecten-Pseudolimea, and Pleuromya-Neoschizodus. The Sakawan age is classified into two subages better than the three formerly proposed by K. ICHIKAWA. The Norian sediments are probably represented by the Nakaiso conglomerate bed, although barren in fossil. The Rhaetic strata are not found at all like other regions in Japan. From the facies-analysis, the Palaeo-Maizuru Bay during the Scythian to Aniso-Ladinian epochs and the Palaeo-Maizuru Inland Sea during the Carnian epoch are assumed. Finally, the orogenic history of the Triassic period in this zone is briefly stated.
We analyzed the possibility of introducing a single stochastic scaling parameter a to describe the spatial variability of soil hydraulic properties, using the soil hydraulic properties of the Hamra field (Russo and Bresler 1981) and the Panache field (Nielsen, Biggar, and Erh 1973). In the traditional approach (Peck, Luxmoore, and Stolzy 1977; Russo and Bresler 1980; Warrick, Mullen, and Nielsen 1977), sets of scaling factors are estimated from the h(s) and K(s) functions. For "perfectly similar media," the two sets of a should be identical. Even though the sets of a in these studies were found to be correlated (table 2), they possessed different statistical properties, and were not identical. Results of structural analyses of the sets of a from the two fields suggested that the spatial structures of the two a-sets are quite distinct, reflecting the different spadal behavior of the h(θ) and the K(θ) functions. Moreover, there was poor correlation between the uncorrelated residuals of the a-sets, indicating that part of the high correlation between the a-sets found in earlier work must stem from the presence of an undetected drift and from correlation between nearby measurements. Under field conditions, the saturated hydraulic conductivity is controlled by the flow of water through large structural voids (macropores), which drain at very small negative values of water pressure. Because of this, we tried eliminating Ks by using relative hydraulic properties instead of the hydraulic properties themselves to estimate the scaling factor sets. For the Hamra field, for which we assumed that the hydraulic properties could be described by the model of Brooks and Corey (1964), we found the resultant sets of scaling factors to be highly correlated (R2 = 0.996) with the same spatial structure, but with slightly different variance. By examining the relationships between the two a-sets implied by the Brooks and Corey (1964) model we saw that (1) in general, both sets will be functions of the range of water saturation values used to estimate them, (2) the correlation between the two sets can be improved for media with broad pore-size distributions, and (3) the two sets will be identical if and only if the relative hydraulic conductivity function K,.(hr) is described by the deterministic function Kr(hr) = hy -2 ("strictly similar media"). This analysis suggests that, for media that are not well described by Kr = hr -2, a scaling factor would be required in addition to a in order to achieve agreement between scaled values of hr(θ) and Kr(θ) at all points. A general model Kr = hr -η was proposed, with η as a second stochastic scaling factor for media that do not obey the restrictive assumptions of macroscopic Miller similitude. In the Hamra field, this modified scaling procedure produced perfect agreement between the scaling hydraulic properties. In the Panache field, with values of η determined from linear regression analysis of the logarithmic transformations of Kr and h,., agreement was improved considerably between the scaled hydraulic properties as compared to the more restrictive scaling procedure. In contrast to the Hamra field, however, there remained some significant differences between the scaled properties. These differences may have been artifacts of the different methods used to estimate the hIs) and the K(s) functions for the Panache field. The results of our analysis suggest that in any transient transport problem involving both K(s) and h(s), the description of their spatial variability requires the use of at least three stochastic variates-Ks , α, and η-not a alone.

Aboriginal migration from South East Asia is the beginning of Australian economic history. Prehistorians have tended to focus on means to sea travel rather than opportunity and motive to migrate. American and Australian measures of sea depth contours throw new light on possible migration paths and the conditions that might have prompted Aboriginal ancestors to move through island SE Asia to Australia. Interpretation of the data depends on a reconsideration of palaeodemography and the introduction of some economic and historical analysis. Several scenarios suggest possible conditions influencing trends and fluctuations in Aboriginal migration over the past 60,000 years.
If the Bosnian crisis of 1908-9 may properly be described as the dress rehearsal for 1914, the Austrian project, announced early in 1908, to construct a railway from the Bosnian border through the Sandjalc of Novibazar helped to set the stage. Part of the original program to link up the Ottoman realm with central Europc by iron highways, this line had been overlooked for decades as finance, engineering, and diplomacy spent themselves on the great trunk line, the Orientbahn, running like a backbone down the Balkans to Constantinople, with a branch connecting Nish with Salonica via Uskub. From Uskub a spur penetrated northward to Mitrovitza; another linked Salonica with Monastir. Though small in itself, the reappearance of the Novibazar scheme heralded the revival of the perennial Austro-Russian rivalry over the Near East in an acute form, sharpened international animosities generally, strengthened latent dreads of Teutonic hegemony over the Balkans, and gave an impetus to a plethora of competing railway projects. In spite of Austria's renunciation of her rights in the Sandjak as part of the settlement attendant upon the annexation of Bosnia-Herzegovina, the railway plan was not abandoned, and until well along in 1909 hopes were cherished that the Sandjak road - even today unconstructed - would be built.
In a joint enterprise, the ground water supplies in some Oases in UAR (namely El Kharga, El Dakhla, El Baharia and Siwa), in Wadi El Natrun (to the west of the Nile Delta), in Ayoun Mousa (West Sinai) and in some places along the Mediterranean Littoral, have been investigated. According to the dating of the water by the C14 method, the age of the artesian water from the Oases is between 25,000 and 40,000 years and the origin is obviously from rain water which fell and infiltrated within the "Nubian Sandstone" layers, occupying almost entirely the southern portion of the western Desert (the water underwent some evaporation before it disappeared in the subsurface as indicated from the loss of the 016). This process took place during one or more of the Pluvial periods which followed (and were not coincident with) the last "Würm" eustatic lowering of the Mediterranean. No infiltration water have presumably recharged the layers in question, so almost entirely fossil water reserves are tapped at present. The quantities of such reserves are unknown. More ancient waters, however, may be expected to the north of El Kharga and El Dakhla Oases. Such waters may- to their greater portions - enter these two oases from that direction. On the other hand, little or almost no water is expected to feed the reservoir from the opposite direction.

Bilingual education is the use of the native tongue to instruct limited Englishspeaking children. The authors read studies of bilingual education from the earliest period of this literature to the most recent. Of the 300 program evaluations read, only 72 (25%) were methodologically acceptable - that is, they had a treatment and control group and a statistical control for pre-treatment differences where groups were not randomly assigned. Virtually all of the studies in the United States were of elementary or junior high school students and Spanish speakers; The few studies conducted outside the United States were almost all in Canada. The research evidence indicates that, on standardized achievement tests, transitional bilingual education (TBE) is better than regular classroom instruction in only 22% of the methodologically acceptable studies when the outcome is reading, 7% of the studies when the outcome is language, and 9% of the studies when the outcome is math. TBE is never better than structured immersion, a special program for limited English proficient children where the children are in a self-contained classroom composed solely of English learners, but the instruction is in English at a pace they can understand. Thus, the research evidence does not support transitional bilingual education as a superior form of instruction for limited English proficient children.
Since the study of economic development began in earnest at the close of the Second World War, academics and policymakers have debated the appropriate role of public policy in developing economies. East Asia has a remarkable record of high and sustained economic growth. From 1965 to 1990 its 23 economies grew faster than those of all other regions. Most of this achievement is attributable to seemingly miraculous growth in just eight high performing Asian economies (HPAEs)-Japan; the "four tigers": Hong Kong, the Republic of Korea, Singapore, and Taiwan; and the three newly industrializing economies (NIEs) of Southeast Asia, Indonesia, Malaysia, and Thailand. The East Asian economies provide a range of policy frameworks-extending from Hong Kong's nearly complete laissez faire to the highly selective policy regimes of Japan and Korea. The coexistence of activist public policies and rapid growth in some of the East Asian economies-especially Japan, Korea, Singapore, and Taiwan-has raised complex and controversial questions concerning the relationship between government, the private sector, and the market. This essay looks at four public policy lessons of the East Asian miracle. Section 1 argues that the eight HPAEs can be grouped together and distinguished from other low- and middle-income countries on the basis of their rapid, sustained, and shared growth. Section 2 examines the controversy over the sources of growth in the HP AEs and presents evidence on the relative roles of accumulation and total factor productivity (TFP) change. Section 3 discusses two aspects of public policy in East Asia that conform to the conventional wisdom concerning good development policy-macroeconomic management and broad-based educational policies. Section 4 examines two more controversial issues -the significance of the HPAEs' export push strategies and industrial policies for TFP change. It concludes that export orientation rather than selective intervention played the dominant role in increasing economywide TFP growth rates.
