This article is concerned with the specification and estimation of relationships whose dependent variable is qualitative in nature (such as "yes" or "no"). It discusses logit equations with and without interaction, and the estimation procedure is generalized least squares. Part I deals with dependent variables that take only two values, part II with variables taking more than two values, and part III describes informational measures for the explanatory power of the determining factors. The discussion of more advanced technical matters is contained in various appendixes.
In this chapter we develop an agenda for future research on the personalization of politics. To do so, we clarify the propositions of the personalization hypothesis, critically discuss the normative standard on which most studies base their evaluation of personalization, and systematically summarize empirical research findings. We show that the condemnation of personalization is based on a trivial logic and on a maximalist definition of democracy. The review of empirical studies leads us to question the assumption that personalization has steadily increased in all areas of politics. Finally, our normative considerations help us develop new research questions on how personalized politics affects democracy. Moreover, this review also makes clear that another weakness of today's empirical research on the personalization of politics lies in methodological problems and a lack of analysis of the impacts of systemic and contextual variables. Consequently, we suggest methodological pathways and possible explanatory factors for the study of personalization.
One of the byproducts of World War II of which society is hardly aware is the new stage of development which the social sciences have reached. This development indeed may prove to be as revolutionary at the atom bomb. Applying cultural anthropology to modern rather than "primitive" cultures, experimentation with groups inside and outside the laboratory, the measurement of sociopsychological aspects of large social bodies, the combination of economic, cultural, and psychological fact-finding, all of these developments started before the war. But, by providing unprecedented facilities and by demanding realistic and workable solutions to scientific problems, the war has accelerated greatly the change of social sciences to a new development level. The scientific aspects of this development center around three objectives: (1) Integrating social sciences. (2) Moving from the description of social bodies to dynamic problems of changing group life. (3) Developing new instruments and techniques of· social research. Theoretical progress has hardly kept pace with the development of techniques. It is, however, as true for the social as for the physical and biological sciences that without adequate conceptual development, science cannot proceed beyond a certain stage. It is an important step forward that the hostility to theorizing which dominated a number of social sciences ten years ago has all but vanished. It has been replaced by a relatively wide-spread recognition of the necessity for developing better concepts and higher levels of theory. The theoretical development will have to proceed rather rapidly if social science is to reach that level of practical usefulness which society needs for winning the race against the destructive capacities set free by man's use of the llatural sciences. I should like to survey certain concepts and theories which have emerged mainly from experimental research. They concern: (a) Quasi-stationary social equilibria and social changes. (b) Locomotion through social channels. (c) Social feedback processes and social management. The last two of these will be dealt with in a later article. A cursory introductory discussion of certain aspects of the present state of affairs in social science is included here for those readers who are interested in the general background of these concepts and in the problems from which they have sprung.

Agglutinated foraminiferal assemblages from the Oligocene section of an exploration well drilled in the distal part of the Congo Fan are fully documented and interpreted for palaeoenvironment. A total of 65 ditch cutting samples were analysed at 10 m intervals, from 3630 to 4270 m below rotary table. An average of 170 specimens were extracted per sample, with over 100 species being documented and described using SEM and light photography. The results reveal the most taxonomically diverse deepsea Oligocene fauna yet described. Six assemblages have been defined and analysed with Correspondence and 'Morphogroup' Analysis. These are 1. Nothia robusta / Reticulophragmium Assemblage (4110-4270 m), 2. Nothia robusta / Scherochorella congoensis / Discammilloides sp. 1 Assemblage (4000-4100 m), 3. High diversity Reticulophragmium Assemblage (3870-3990 m), 4. Portatrochammina profunda Assemblage (3790-3860 m), 5. Nothia latissima Assemblage (3730-3780 m) and 6. Low abundance Assemblage (3630-3720 m). Palaeobathymetric estimates range from middle -lower bathyal based on comparison with living taxa and morphogroup distributions. These results extend the known stratigraphic range (last occurrences) of Reticulophragmium amp/eetens into the Oligocene in the Atlantic, and possibly also Paratrochamminoides gorayskii, Paratrochamminoides olszewskii, Trochamminoides aff. proteus, Trochamminoides subcoronatus, Haplophragmoides horridus and Haplophragmoides walteri, although reworking is documented with these species. Results also extend the known first occurrences of Recurvoides azuaensis, Spiropsammina primula, Cyclammina aff. orbicularis, Discamminoides sp. and Glaphyrammina americana into the Oligocene. Large scale variations within faunas are largely assigned to documente d variations in sand content, where higher proportions of sand generally coincide with reduced diversity and abundance along with a dominance of opportunistic species such as Nothia robusta, Nothia latissima and Ammodiscus latus. A major excursion in the infaunal morpho group, suspension-feeding morpho group and diversity and abundance within Assemblage 2 is termed the 'Scherochorella Event', and does not correlate with an increase in sand. This fauna is thought to be the result of lower oxygen conditions allowing the dominance of the low oxygen morphotype Scherochorella congoensis and the opportunistic species Nothia robusta. Deep-water circulation in the Atlantic at this time is generally thought to have been strong, and this event suggests that there may have been a temporary expansion of the oxygen minimum zone during the Late Oligocene, coinciding with increased benthic 8180 values, global cooling, and increased upwelling associated with a stronger polar front. The otherwise high diversity of the fauna in the well supports the interpretation of well-oxygenated conditions.

Several types of symbolic weapons are portrayed in the hands of divinities on the most diverse artistic works of the third millennium, such as maces or sceptres, daggers, spears. hows and arrows. There is also a weapon which has a form similar to a sickle. Data referring to it may be found - in addition to the representations - in written sources. We learn from the Cy1. «A» of Gudea that the king, the en-priest of Ningirsu, was the first to reach the cedar mountains and fell the cedars with his big axe. He then made the SAR.UR, the «Floodstorm Weapon» of his god, the right hand of Lagas. The inscription of statue «B» tells us the Same. When Gudea built the temple of Ningirsu, the god aided him in reaching the cedar mountains from which he took gigantic logs to make a weapon for his god: the SAR.UR, having the power ofa flood storm and the SAR.GAZ, a mace with seven copper knobs.
This study is part of a larger work whose aim is to examine the historical significance of the tens of thousands of Islamic silver coins or dirhams which appeared in Eastern Europe during the pre-Mongol era. The first part of this work explored the questions of when and how dirhams first reached European Russia. Very briefly, this initial study led to the following conclusions: 1. Dirhams first reached Eastern Europe about 800 A.D., as R. Fasmer (Vasmer) argued a half-century ago. 2. The earliest dirham hoards from Eastern Europe are almost identical in composition with contemporaneous Near Eastern hoards (both contain a predominance of 'Abbasid coins struck after 769 in Iraq and North Africa). This suggests that the earliest Eastern-European hoards were composed from the Near-Eastern coin stock of the time. 3. The earliest dirham hoards from Eastern Europe are completely different in composition from the contemporaneous hoards found in Transoxiana indicating that the earliest dirhams to reach Eastern Europe did not come via Central Asia. 4. An analysis of the early Caucasian dirham hoards revealed that the composition of some of these hoards differs from that of Eastern-European and Near-Eastern hoards in that the Caucasian hoards contain a higher percentage of dirhams from South-Caucasian mints and a lesser percentage of coins from North-African mints. This suggests that these hoards were composed of dirhams imported from the Near East which had circulated in the Southern Caucasus for some time before being deposited. 5. Other early dirham hoards from the Caucasus, however, are very similar in composition to contemporaneous Near-Eastern and Eastern-European dirham hoards. This suggests that these hoards were composed of coins which were apparently being transported to Eastern Europe from the Near East and were buried accidentally while in route through the Caucasus. In short, the first segment of this research concluded that dirhams began to reach Eastern Europe around the year 800 and that they were imported by the Caucasus or Caspian route from the Near East. The purpose of this study is to investigate the historical circumstances which would explain why dirhams were first brought by the Caucasus or Caspian route to Eastern Europe in the early ninth century. It is pertinent to note that, to the best of my knowledge"no one has yet addressed this fundamental question in any depth. Consequently, in discussing this issue, it is not our intention to claim that the thesis which will be put forward is irrefutable or that no other thesis could explain the available data. Rather, the objective is to raise the question of why dirhams first reached Eastern Europe around 800 A.D. by the Caucasus-Caspian route and to suggest a possible solution. This study should thus be considered as the presentation of a working hypothesis which will hopefully inspire others to examine a basic question of medieval Eurasian history which has been too long ignored.
A brief presentation of iron chemistry is made with emphasis on those aspects relevant to siderophore biochemistry. Siderophore structure and biosynthesis is described. The underlying chemistry associated with, 1, the movement of iron(ill) complexes across membranes and 2, the removal of iron from such complexes is discussed in detail. The ability of siderophores to interact with other metals is considered. Finally, the role of siderophores in infection and their clinical potential as iron scavenging molecules are reviewed.

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.
The results of the pre:lent investigation may be summarized as follows: (1) The heat content of carbon steels at high temperatures was determined by the mixture method, while the oxidation of the specimen was prevented by passing a purified hydrogen gas through the furnace. The specimens were twelve kinds of steels with different carbon contents from 0.09 % to 2.84 % and the range of temperature was 23~250°C. (2) According to A. Meuthen, the specific heat is constant below the A1 point, but the present writer showed that the specific heat is only constant above the A3 point, and that below this point, it increases with the rise of temperature. (3) The quantity of heat for the dissolution of pearlite in iron was determined by measuring the heat content above and below the A1 point. This heat increases proportionally with the content of carbon, reaches a maximum at 0.9 percent and ends at 6.7 percent. For the dissolution of I gr. of carbon in iron, a heat of 1760 calories is required, while, 16.1 calories are necessary for the dissolution of 1 gr. of pearlite in iron. (4) From the heat content-concentration curve, it was found that, the mean specific heat of cementite increases with the rise of temperature; it is 0.149 at 150°C and 02.20 at 850°C. (5) It was observed that the specific heat of the carbon poles with 98 %C increases almost linearly up to 700°C, and afterwards its rate of increase gradually diminishes. (6) It is confirmed by experiments that the A1 transformation is a function of temperature and time, but that the A2 transformation is a definite function of temperature only. (7) From the heat content-concentration curves, the heat of transformation from martensite to pearlite was obtained and found to be proportional to the carbon content. (8) The heat of transformation from austenite to martensite, or that from martensite to pearlite, increases proportionally with the content of eutectoid carbon. The heat of transformation from austenite to martensite for a eutectoid steel amOlmts to 5.9 calories.
The Asian financial crisis of 1997-98 was one of the most dramatic economic events of recent times, which raised many questions regarding the appropriate policy response to financial crises. This paper reviews the experience of this crisis, focusing on the overall strategy of crisis management and the way that strategy was implemented including, with regard to official and private financing, structural reforms, and monetary and fiscal policies.
This article examines the type of economic analyses of capitalism presented by leading exponents of the neoclassical, marxian, Austrian and institutionalist schools of economic thought. Although each school has something to offer, it is argued that all except the institutionalist school are largely insensitive to different types of structure within capitalism and are blind to the cultures and institutions which characterize different kinds of capitalism. This conclusion is reached by addressing three issues: the problem of universal and specific assumptions in economic analysis; the question of "necessary impurities" in an economic system; and the relationship between actor and structure. It is concluded that institutional economics is most sensitive to the immense actual and potential variety within capitalism itself, and recognizes that the development of different capitalist systems can be divergent rather than convergent.
An attempt has been made in this article to critically survey the field of low Reynolds number flows, with particular regard to the hydrodynamic resistance of particles in this regime. A remarkable burgeoning of interest in such problems has occurred wlthin the past decade. Significant advances have been recorded on both the theoretical and experimental sides, with the former gains far outdlstancing the latter m scope. Problems which would have been impossible to solve rigorously before the advent of singular perturbation techniques are now being regularly solved, though hardly in a routine fashion; insight, intuition, inspiration, and ingenuity are still the order of the day. For those interested in direct engineering applications of the material covered by this review, the perspective from which many of the more general results set forth here should be viewed is, perhaps, best illustrated by an example: The resistance of any solid particle to translational and rotational motions in Stokes flow may be completely calculated from knowledge of a set of 21 scalar coefficients (Section II,C,l). While it seems highly improbable to expect that all these coefficients could be experimentally measured in practice, except perhaps in the trivial case of highly symmetrical bodies for which many of the coefficients vanish identically, this does not detract from the conceptual advantages of knowing exactly how much one does not know. Having an ideal goal against which the extent of present knowledge can be gaged permits a rational decision as to how to optimize one's investment of time, effort, and money in the pursuit of additional data. Furthermore, with the development of high-speed digital computers it may soon be possible to calculate all these coefficients for any given body (O 1 b). The general theory provides a rigorous framework into which such knowledge may be embedded. Use of symbolic" drag coefficients" (Section II,C,2) and symbolic heat- and mass-transfer" coefficients" (Section IV,A) furnishes a unique method for describing the intrinsic, interphase transport properties of particles for a wide variety of boundary conditions. Here, the particle resistance is characterized by a partial differential operator that represents its intrinsic resistance to vector or scalar transfer, independently of the physical properties of the fluid, the state of motion of the particle, or of the unperturbed velocity or temperature fields at infinity. Though restricted as yet in applicability, the general ideas underlying the existence of these operators appear capable of extension in a variety of ways. A recurrent theme arising throughout the analysis pertains to the screwlike properties of particles and of their intrinsic right- and left-handedness (Sections II,C, 1; II,C,2; III,C and IV,B). Such properties reflect an inseparable coupling between the translational and rotational motions of the particle. Helicoidally isotropic particles furnish the simplest examples of bodies manifesting screw-like behavior. These particles are isotropic, in that their properties are the same in all directions. Yet they possess a sense, and spin as they settle in a fluid. These id eas are likely to be of interest to microbiologists, biophysicists, geneticists, and others in the life sciences for whom handedness and life are intimately intertwined. The microscopic dimensions of the objects of interest to them insures ipso Jacto that the motion takes place at very small Reynolds numbers. Readers interested in an elementary but broad survey of sense in the physical and biological sciences are referred to Gardner's delightful book "The Ambidextrous Universe" (01). First-order corrections to the Stokes force on a particle, arising from wallor inertial-effects, can be directly expressed in terms of the Stokes force on the body in the absence of such effects. Thus, with regard to wall-effects in the Stokes regime, Eq. (135) expresses the force experienced by a particle falling in, say, a circular cylinder, in terms of the comparable force experienced by the particle when falling with the same velocity and orientation in the unbounded fluid. Equation (139) expresses a similar relationship for the torque on a rotating particle in a circular cylinder, as does Eq. (166) for the first-order interaction between two particles in an unbounded fluid in terms of the properties of the individual particles. Analogously, Eq. (234) expresses the inertial correction to the Stokes drag force in terms of the Stokes force itself. A comparable relationship exists (Section IV, A) between the heat-transfer coefficient at small, nonzero Peelet numbers and the heat-transfer coefficient at zero Peelet number-that is, the coefficient for conduction heat transfer. Finally, Eqs. (78)-(79) (or their symbolic operator counterparts) permit direct calculation of the Stokes force and torque experienced by a particle in an arbitrary field of flow solely from knowledge of the elementary solutions of Stokes equations for translation and rotation of the particle in a fluid at rest at infinity. The utility of already available knowledge is thus greatly extended by the existence of such relations. It permits one whose interests lie entirely in the macroscopic manifestation of the motion, e.g., the force and torque on the body, to bypass the oftentimes difficult problem of obtaining a detailed solution of the equations of motion, and to proceed directly to the computation of the force and torque on the body from the prescribed boundary conditions alone. The calculation is thereby reduced to a quadrature. The contents of this review may be read simultaneously from two different points of view. First and foremost it may be regarded as a compendium of recent advances in low Reynolds number flows. Secondly, from a pedagogic viewpoint it may be profitably used to illustrate the direct application of invariant techniques, that is, vector-polyadic and tensor methods, to a class of physical problems. Because of the relative simplicity and rich variety of physical problems associated with low Reynolds number motions, intuitive arguments may be employed to gain insight into the nature of polyadics and tensors; the role played by the concept of direction as a primitive entity is brought out here to a degree not usually found in standard works on tensor analysis.
Human mimicry
(2009)
Human mimicry is ubiquitous, and often occurs without the awareness of the person mimicking or the person being mimicked. First, we briefly describe some of the major types of nonconscious mimicry -verbal, facial, emotional, and behavioral- and review the evidence for their automaticity. Next, we argue for the broad impact of mimicry and summarize the literature documenting its influence on the mimicry dyad and beyond. This review highlights the moderators of mimicry as well, including the social, motivational, and emotional conditions that foster or inhibit automatic mimicry. We interpret these findings in light of current theories of mimicry. First, we evaluate the evidence for and against mimicry as a communication tool. Second, we review neuropsychological research that sheds light on the question of how we mimic. What is the cognitive architecture that enables us to do what we perceive others do? We discuss a proposed system, the perception-behavior link, and the neurological evidence (Le., the mirror system) supporting it. We will then review the debate on whether mimicry is innate and inevitable. We propose that the architecture enabling mimicry is innate, but that the behavioral mimicry response may actually be (partly) a product of learning or associations. Finally. we speculate on what the behavioral data on mimicry may imply for the evolution of mimicry.
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.
Neither classical scholars nor medical bibliographers have yet given adequate attention to Renaissance Latin translations of Galen. The German editors of the Corpus Medicorum Graecorum have concluded that detailed study of these versions will seldom aid materially in the reconstruction of the Greek text. Mediaeval Latin translations on the other hand, which are both literal and based On manuscripts some two to three centuries older than those used by the editors of the Aldine editio princeps, have been diligently studied by textual critics. The classical specialist tends therefore to underestimate the interest oflater versions for the historian ofideas, the medical historian and the professional bibliographer. Nevertheless, these translations provide material for the treatment of several topics not yet fully investigated: the rise and fall of Galen's reputation in the Renaissance; the relative importance attached to his works and their place in the contemporary medical curriculum, the attitude of the scholar-physicians to the task of translation, and their contribution towards the new medical terminology. A necessary task preliminary to any such investigation is the exhaustive listing of printed translations and editions, for the existing bibliographies are far from adequate. It is hoped that the present census, based on the holdings of just under a hundred libraries.
This article examines the negotiating process between the Brazilian state and transnational auto companies. It argues against dichotomous frameworks that emphasize either economic or political variables in shaping foreign direct investment and in favor of a more complicated bargaining framework that takes into account the strategic objectives of state policy as well as the form and timing of firm investment. Using archival evidence and interviews, the article documents the implantation of the industry; it concludes that the process of finn entry into Brazil must be understood in light of the policies and institutions that made the threat of market closure and the deadlines credible and made it costly for firms not to participate on schedule.
Angkor Wat's "Churning of the Sea of Milk" bas-relief masterpiece is unique among "Churning" depictions for its naturalistic presentation of fishes and other aquatic animals. Their behavior clearly indicates that they have been poisoned, as related in the myth of the Churning. The poisoned fish are being cut in two by the sword of Suryavarman II as Vishnu. Also notable is the inclusion of the mythical beast known as gajasimha. The little known Angkor Wat bas-relief called the "Fete nautique des Dvaravati", also a masterpiece, realisticany portrays people making music, playing chess, fishing, hunting, and engaged in other aeti vities, in the midst of a forested wetland filled with birds, fish, crocodiles and other animals. The scene also portmys two royal pleasure boats, one with Garuda on its prow and the other with a gajasimha. Gajasimha is an Indian and Khmer makara associated in Khmer iconography with the Hindu god Vishnu. Suryavarman II was one of the few Khmer kings to be identified with Vishnu. Garuda and gajasimha were employed repeatedly to symbolize this relationship. This symbolism is employed in several significant innovations in Khmer iconography. These include replacement of the naga Ananta or Sesha by a gajasimha in representations of Vishnu Anantasayin; the distinctive "Garuda-gajasimha" balustrades, and use of the head of gajasimha or its elephantine trunk as the apical finials (dong chivea. Iliya, or chota) on Cambodian, Laotian, and Thai Buddhist temples. Fish figure importantly in numerous Bayon bas-reliefs. Many of these depict ordinary people engaged in activities such as cooking, gambling, cockfighting, and fishing. Others apparently depict events or incidents in the life of Jayavarman VII including his military victories, building activities, and apotheosis as Jayahuddha or Buddha-King, as well as his tolerant attitude towards other religions. There are also indications that he had an abiding interest in natural history.

The study adressed 4 basic issues: (1) What are the substantive contents of human values? (2) Can we identify a comprehensive set of values? (3) To what extent is the meaning of particular values equivalent for different groups of people? (4) How are the relations among different values structured? These issues required resolution before the antecedents and consequences of value priorities, or cross-cultural differences in such priorities, could be studied effectively. Substantial progress has been made toward resolving each of these issues.
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.
Northern Chile, which includes the extremely arid Atacama Desert and the semiarid Andean Highlands, has more than 100 basins with interior drainage; most contain salars (salt-ilncrusted playas). The area of interior drainage totals more than 38,000 square miles, within which salara and clay playas extend over a total area of about 2,800 square miles. In addition, hills and valleys in the Atacama Desert are extensively covered either with a thin hard saline crust, chiefly salt-cemented soil, or with a powdery soil that has a high content of saline material, chiefly anhydrite and gypsum. The region has an exceptional variety of types of hard saline crusts that are generally rare in other deserts, and many morphological and structural salt features, some of which may be unique. Soft saline crusts and clay playas, more characteristic of arid regions elsewhere, are also present. Hard salar crusts have formed by deposition of saline material in open water or by capillary migration and evaporation of near-surface ground water. Such crusts generally range from a few inches to several feet in thickness. Locally, crusts may attain thicknesses of several tens of feet, and one salar, Salar Grande, is a basin filled with high. purity rock salt to a local depth of at least 560 feet. Six general types of hard salar crusts are distinguished: (1) layered massive rock salt with a rugged surface, (2) slabby or nodular silty rock salt, (3) rugged gypsum or anhydrite, (4) massive coarsely crystalline rock salt, (5) smooth rock salt, and (6) silty nitrate-bearing saline crust. Soft surfaces or crusts include moist gypsum-bearing crusts, which commonly contain nodules and layers of ulexite in Andean salars, and moist to dry puffy soils and crusts that contain gypsum, thenardite and mirabilite as the principal saline constituents. An unusual chemical feature of the salars and the desert soils of northern Chile is the general paucity of carbonate minerals (for example, trona, calcite, and aragonite) which are widespread in other desert regions. Among the many morphological and structural features that can be recognized in and near salars of northern Chile, the most unusual occur in hard rock-salt crusts, which in themselves are scarce in other arid regions. Included are features due to corrosion of rock-salt crusts by windblown water or free-flowing surface water, such as: (1) salt cusps and crenulate margins of salars, (2) salt channels, (3) salt pseudobarchans, and (4) salt tubes. Constructional features in the salars include: (1) gypsum buttresses at borders of saline ponds, (2) salt veins, (3) salt stalactites, and (4) salt cones. In some salars, new fresh-water springs have formed steep-walled brine pools in thick rock-salt crusts. Prominent salt cascades and constructional salt terraces have been built up in one Andean valley by springs that are fed by brine from a nearby salar (Salar de Pedernales). Sag basins and prominent scarps occur along faults that cut through the salt mass of Salar Grande. Of, the 67 closed basins in the Andean Highlands of northern Chile, at least 35 show shorelines or deltas of former perennial lakes. Today only flve perennial lakes occur in this area. The former lakes probably formed at one or more times during the Pleistocene and perhaps continued to form into Holocene time. They indicate a climate that was either more rainy or cooler, or both, during the time of their formation. However, the absence of glacial features throughout most of the northern Chilean Andes indicates that the climate during the Pleistocene glacial stages was not greatly different from today's climate. It is estimated that perennial lakes would form in nearly all thil Andean basins if the mean annual rainfall of the region above 10,000 feet in altitude were increased to 15 inches from its present 8 inches, and if the mean annual temperature were about 2° F. less than it is at present.
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.
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.
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.

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.
The Tanzawa mountainland consists of a pyroclastic complex chiefly of basic composition which is intruded by a large mass of quartz-diorite at the center. This complex, well-known as the Misaka series, is the products of largescale geosynclinal volcanisms which took place during the period from the latest Oligocene to the middle Miocene in age. As compared with other geologic units, the present complex is characterized by its unusually thick accumulation of pyroclastic rocks, and by the intense hydrothermal alteration of the rocks, furnishing us an excellent section of the so-called green tuff series in the southeastern region of the Fossa Magna. Also the development of the products of interesting metamorphism of the quartz-diorite to the surrounding pyroclastic rocks is a feature uncommon in the other green tuff series of the above region. The crustal movement occurring during the volcanisms, however, make the structure of this complex highly complicate. In addition, the topographically unfavourable condition of this mountainland causes great hindrance to the geological investigation of this complex. Accordingly, the true natures of the complex remain unknown both stratigraphically and petrographically. Since 1948, the writer has been studying on the complex distributed in the eastern region of the Tanzawa massif from the volcano-stratigraphical point of view, some of the results of which have been published as miscellaneous reports. The main scope of this paper is to describe the stratigraphy, petrography, and the tectonic history of this complex. In this paper are also discussed the characteristics of the volcanic activities and the alterations represented by the same complex.
In addition to a series of questions closely associated with the spatial structure of the Sanctuary of Artemis, from where our work had started, the research has also raised, due to continuous confrontation, matters of greater complexity relating to the structure of the whole city´s layout. Here a brief account is given of the progress made and of the working hypothesis inferring from.

Der Verfasser untersucht die formalen und materialen Voraussetzungen der Messung in der Physik. Insbesondere sucht er zu zeigen, daß die üblichen Formulierungen, die etwa besagen, daß eine Messung eine Korrelation zwischen Zahlen und nichtnumerischen Gebilden bedeute, oder daß eine Messung im Grunde auf die Feststellung einer raumzeitlichen Koinzidenz hinauslaufe, zum mindesten recht unvollständige Charakterisierungen des physikalischen Verfahrens darstellen; in der Arbeit wird eine genauere Analyse versucht. Diese geht aus von den formalen Eigenschaften der Größenordnung, die jeder Messung zugrunde liegt. Eine geeignete Formulierung dieser Eigenschaften bietet sich dem Verfasser in den zwölf "Axiomen der Quantität" die in der S. 315 angegebenen Gestalt von Hölder aufgestellt worden sind. ...

The present paper deals mith the results of an environniental isotopic study in western Thessaly valley, carried out during the period 1968 - 1971. The isotopes used are 18O, D, Tritium, 18C and 14C. By the interpretation and evaluation of these resiilts useflil informations as regards the soiirce of recharge, the recharge mechanisrn and the dynamics of the flow system of the valley are provided.
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.
