The article presents titles and abstracts of papers submitted at a meeting held in Cambridge, Massachusetts in 1938. The paper "The Sequent Occupance of a Boston Suburban Community," presented by Edward A. Ackerman focuses on areas surrounding the Boston metropolitan district. The proximity of a large city market, plots of level land and fertile soil determine the existence of these suburban fanning communities. The article "The Recession of Victoria Falls," by Wallace W. Atwood. The world famous falls on the Zainbesi have had a strange and remarkable history in recession. The gorge is serpentine with many curious off-shoots, and located on the floor of a broad and much older flat-bottomed valley. Today the water tumbles over a ledge, fully a mile in length, and into a very narrow chasm 350 ft. deep.

The article focuses on four papers by the geographer, Ralph H. Brown. The writings of Brown in historical geography of the U.S. are among the notable contributions to American geography. His many articles, as well as his two major works, "Mirror for Americans," and "Historical Geography of the United States," demonstrate his concept of historical geography with eminent clarity and with scholarly regard for the origins of that concept. He observed existing geographic facts and he searched historical records.

The article presents a brief outline of papers presented at the thirteenth annual meeting of The Society for Psychophysiological Research that was held between October 25 and 28, 1973 at the Galvez Hotel and Motel in Galveston, Texas. Members of the program committee were professors Peter J. Lang, Hiram E. Fitzgerald and David T. Graham. Some of these papers include "Heart Rate Variability and Heart Rate Conditioning in Human Newborns," by L.E. Stamps, "Habituation and Dishabituation of Cardiac Orienting in Human Newborns," by C.D. Adkinson and W.K. Berg and "Developing Changes in Response Recovery," by E. Scott and M. Lewis.

The article presents abstracts of the papers presented at the 63rd annual meeting of the Association of American Geographers, Saint. Louis, Missouri. The meeting took place in April 1967. The paper "Defense and the Morphology of Certain Settlements in the Western Mediterranean," discusses economic growth. Another paper "Approach to a Generating Model for Climatic Statistics," discusses a set of probability models for generating climatic statistics. After a brief review of previous work on this subject, a model based on moving waves superimposed, on standing waves in the zonal winds is outlined.

The article presents abstracts of papers presented at the 61st Annual Meeting of the Association of American Geographers, Columbus, Ohio on April 18-21, 1965. The paper on the "The Use of Fodder and Livestock Units in Agricultural Geography: A Case Study of Soviet Land Use Policy," by John Anderson focuses on the need for better research tools in agricultural geography. The fodder unit, a concept development by livestock nutritionists, while having some limitations, appears to have some potential for research in agricultural geography.

The article presents a collection of abstracts of the research papers presented at the 57th annual meeting of the Association of American Geographers, which was held in Miami Beach, Florida in April, 1962. The papers listed here includes "The Campus Fringe--A Landscape Phenomenon," by John Alexander. This paper analyses the problems related to the expansion of universities including that of campus fringe, the area which surround a college or university. What are the problems of campus fringes, How have these problems been faced by different schools, are there any principles which research geographers might discover which would be useful to campus authorities facing decisions regarding expansion problems, all these points have been considered by the researcher.

The article presents titles and abstracts of papers related to geography. In the paper Outlines of Some Foreign Settlements in Nebraska the author holds that Nebraska was settled principally by people form groups called settlements. latter tended to form groups called settlements. The paper shows for a few of these the origin, development and changes in form. Careful mapping shows this to be somewhat in error. In the article The Place of Geodesy in Scientific Geography the article holds that Geodesy is one of the important branches of geography and is essential in the determination of the shape and size of the earth, a knowledge of which is necessary in geographic research and investigations.

This article presents abstracts of papers presented at the twelfth annual meeting of the Society for Psychophysiological Research, which was held at the Hotel Sheraton-Plaza in Boston, Massachusetts on November 9-12, 1972. The paper presented by J.C. Jackson and F.K. Graham of the University of Wisconsin cites threshold intensity effects on two orienting response components. Sokolovian theory suggests that the orienting response should be large near psychophysical threshold, fall to a minimum around 10-20 decibels and then rise again until it is depressed by competition with the defense reflex.

The article presents abstracts of papers presented at the tenth annual meeting of Society for Psychophysiological Research, which was held at Roosevelt Hotel in New Orleans, Louisiana, from November 19-22, 1970. Some abstracts of papers that were presented at the meeting are "Response Imperativeness and the Cardiac Wave-Form During the Preparation of a Motor and "Mental" Reaction Response," by Gary E. Schwartz and J. Higgins and "Respiration and Heart Rate Indices of Reaction Time," by Stephen W. Porges.

This article presents abstracts of papers presented at the seventh annual meeting of Society for Psychophysiological Research held at the Vacation Village Hotel in San Diego, California from October 19-22, 1967. One of the papers explored monocular visual evoked potentials as an index of maturity of human neonates. Another paper focused on habituation differences to tactile stimulation for waking and sleeping infants. In this paper the role of state in determining a psychological or physiological response is not disputed.

The article presents summaries of papers delivered at the 125th annual meeting of the American Statistical Association. The meeting took place on September 1965 in Philadelphia, Pennsylvania. In the paper "On the Construction of Stochastic Working Life Tables," by Haskel Benishay, stochastic working life tables are constructed and evaluated. The essence of the construction of stochastic rather than the traditionally deterministic working life tables is in the utilization of the realistic assumptions that the number of births, the number of entries into the labor force, the duration of life, and the duration of working life, are random variables. The end result is a working life table with a double entry in each cell rather than the single traditional one. The implications of this approach for the evaluation of fluctuations in various subcomponents of the labor force are evaluated. Another paper "Measuring Elasticities of Air Travel," by Samuel L. Brown, summarizes research on the response of demand for air travel to differences of fares, incomes, and elapsed travel time. There are three kinds of studies. Multiple regression studies of time series of air traffic, fares and income in the national domestic market yield short-period fare elasticities and income-elasticities. A quarterly first-difference model stands well the usual statistical tests.

The article presents an alphabetical list of abstracts and titles of abstracts submitted for papers presented at meetings of the American Statistical Association and Biometric Society in Washington D.C., in December 1967. The abstract "Indians and Smudges on the Census Schedule," by Donald S. Akers and Elizabeth A. Larmon, is an explanation of how certain anomalies in the reported characteristics of American Indians in the 1960 Census are to be explained by systematic smudging of the census schedules. The abstract "Input-Output and the Economy," by Clopper Almon explains that input-output and regression analysis were once considered rival tools for analysis of the economy. In those days, the constancy of the coefficients seemed a crucial issue in deciding whether or not to use input-output. Today, thanks to the progress in computer hardware and model building technique, regression analysis and input-output complement one another and the constancy of coefficients need be assumed only where we know of no better assumption.

Screening of filter paper urine specimens for metabolic and transport disorders has been conducted in Massachusetts for the past few years. Disorders not identifiable by blood screening are detectable by this program. Specimens are obtained routinely by the parents on 3- to 4-week-old infants and mailed to a central laboratory. Testing is performed on discs punched directly from each specimen utilizing several methods of paper chromatography. Cystinuria, histidinemia, Hartnup disease, and iminoglycinuria (Group I) is each approximately as frequent as is phenylketonuria (PKU) in Massachusetts (1:14,219). Other disorders identified, including the hyperglycinemias, argininosuccinic aciduria, hyperlysinemia, hyperornithinemia, and the Fanconi syndrome (Group II) each has a frequency that seems to be no greater than 1:200,000 of the population. Transient abnormalities, such as tyrosinuria-tyrosyluria, generalized hyperaminoaciduria, iminoglycinuria, cystine-lysinuria, and others have been noted. Also diaper creme or fetal contamination of specimens as well as the ingestion of formulas supplemented with DL-methionine, of ampicillin, or of n-acetylcysteine may result in unusual amino acid patterns. A program such as this requires multiple testing procedures, access to proper evaluative and investigative facilities, and cooperation among the various participating groups. The total expense of this program is about $80,000 per year or approximately $1.00 per infant tested.

Industrial espionage has been raised to a sophisticated level today, but pirating labor is still the quickest and surest way to get at a competitor's trade secrets. The loss of trade secrets through changes in employment was a principal topic of discussion at the eighth annual conference of the Patent, Trademark, and Copyright Research Institute of George Washington University held in Washington in July 1964. Conferees agreed that losses occur because employers put a price on their ethics and employees on their loyalty. As professor Richard B. Morris has made clear, pirating of workers and interference with contract relations in American history goes back to the colonial period, when both bound servants and hired workers were enticed away from their employers for their labor and their skills. Stolen manufacturing processes were the basis for the establishment of the textile industry in this country. The seduction of workers by pirates of manufacturing processes was a real and present danger to a community of manufacturers along Brandywine Creek in northern Delaware in the early nineteenth century.

There is an urgent need to examine the range of ecosystems that is currently protected in national parks and reserves, to point out those examples that are unprotected and to establish a rational programme of priorities for protecting as complete a series as possible. The International Biological Programme has pioneered the field of large-scale survey work for the collection of data of relevance to this need and has contributed to the development of information retrieval techniques for handling the data. The first part of the paper discusses the rationale of the development of the data base and its modus operandi. The system is illustrated by two examples of retrieval and analysis for specific enquiries; the distribution of four species of Pinus, and the occurrence of grazing, logging and burning in national parks and equivalent reserves in the United States. The second part of the paper deals with system design, details of programming for the data base, and retrieval strategy. It is intended as an independent section which may be skipped if the reader has no interest in the finer points of the data base itself. [ABSTRACT FROM AUTHOR]

The article presents proceedings of the Annual meeting of the Phycological Society of America at the University of Minnesota, Minneapolis, Minnesota, held between August 27-September 1, 1972. All sessions of the program at which contributed papers are presented were joint sessions of the Phycological Society of America and the Phycological Section of the Botanical Society of America. Various research papers were presented at the annual meeting. Section one was on Nuisance Algae and Bloom Phenomena. Section two was on Physiology and Biochemistry.

The paper presents comparison between the associations of British and American voluntary associations. The development of postwar research on the structure and functioning of voluntary associations has been uneven, and there have been marked differences between British and American research in this field. This paper offers a narrow definition of voluntary associations. It defines voluntary associations as groups in which membership is in no sense obligatory, which have a formal constitution, but which do not have paid officials at the local level. The next section of this paper places the subsequent analysis in context by pointing briefly to the very substantial similarities between research in Great Britain and the U.S. The third section discusses differences in the research environments of the two countries, and suggests their relevance to the main problem. The fourth section assesses the differences in research orientations between the two countries, as it has influenced the study of voluntary associations. The final section considers the effect of these differences upon the functional analyses that have been made.

The article presents information on the 1965 issue of the journal "Sociological Inquiry." The 1954 and 1955 Supreme Court decisions on desegregation are the force that set in motion vast changes that are restructuring the very nature of race relations in the United States. This volume contain recent developments relating to race relations in the United States. Its nine essays touch on several of the major areas in which change occurs or in which old blemishes remain. The paper by Robin Williams, with which this issue begins attempts an overview of what has happened in the last two decades. Most of the papers in this set are themselves reports of research appropriate to Williams' contention that intergroup relations are part of the basic dynamics of modem social systems. Richard Lamanna's doctoral dissertation is concerned in part with the response of the Negro public school teacher to desegregation. Lewis Killian turns his attention to the negotiations between representatives of the white and Negro communities.

The article reports that the U.S. Supreme Court, in Times-Picayune Publishing Co. versus United States, upheld a tying arrangement for newspaper advertising as not violative of the Sherman Act, while enunciating criteria which may make it easier to eliminate tying arrangements under the Clayton Act. The defendant, publisher of the only morning daily newspaper in New Orleans, the Times- Picayune, and one of the two evening papers, the States, adopted a unit system requiring that classified and national display advertisements be placed in both papers. The Supreme Court reversed the District Court's finding that the unit system was a tying arrangement violating Sections 1 and 2 of the Sherman Act.

This paper analyzes the manner in which ethnicity has affected the course of American and Canadian party politics. Specifically, the paper tries to demonstrate that although the social processes involved in the migration of large numbers of ethnics have been relatively similar in both societies, the manner in which the social reality of ethnicity has affected the political structures therein has been quite different. Thus, although successive immigrant groups became the chief political resource of the great American urban party machines, they were able to use the existing political structures for their own purposes. Ethnic groups have derived psychological and more tangible benefits, such as public and party office positions, and have strongly affected the foreign and domestic policy positions of the two major parties. In contrast, Canadian party leaden historically have been able to exploit ethnic cleavages, but rarely have had to play the game of ethnic politics in the maimer of their American counterparts. In fact, ethnicity continues to strongly affect American political structures even as it moves into the realm of an index of more important social facts, while Canadian political structures have remained relatively impervious to ethnic groups despite the fact that ethnicity continues to be a factor of major importance in Canadian social organization.

The article presents a bibliography of periodicals and papers on the history of the American labor. According to the author the scope of this bibliography is, in fact, somewhat narrower than the title suggests, as it has been confined, with one or two exceptions, to learned periodicals. The list of papers on the period of labor development in the U. S. includes "Labor and the Federal Government: 1850-1933," by Albert A. Blum, , "Labor and the Radical Republicans: a Study of the Revival of the American Labor Movement, 1864-1868," by David Montgomery, "Cooperative Community in the North: Brigham City, Utah," by Leonard J. Arrington, "The Experimental Utopia in America," by Maren Lockwood, "The Failure of the Movement by the Unemployed for Public `Works in 1873," by Herbert G.

This paper presents the motivation for the construction of a digital computer simulation of the American military's strategic airlift system, the author's analysis of that system preparatory to the simulation design, and the currently anticipated application of the model to studies of strategic mobility. Emphasis is placed on the estimation of the airlift productivity function for its subsequent utilization in appropriate strategic mobility models employed by the Joint Chiefs of Staff and by the Office of the Assistant Secretary of Defense (Systems Analysis). Those variables suspected of being primary contributors to gains in marginal airlift productivity are delineated in a description of the modules constituting the model. Finally, a sketch of an hypothetical experimental design, permitting the systems analyst to specify sequentially model iterations so as to obtain valid statistical estimates of desired marginal productivities, serves as a conclusion to the paper.

This paper seeks to assess the utility of the transactional model of individual stress. According to the logic of the model, whether persons manifest stress is a multiplicative function of both situational and individual characteristics. The paper briefly discusses possible advantages of the perspective over other frames of reference. Then it describes a pilot study designed to determine whether hypotheses based on the transactional model could be supported empirically. Utilizing interview data from a small probability sample of all adults in the state of Missouri, scales were constructed by an improved method of item analysis for use as indicators of variations in stress and the situational and individual factors. Comparing stress scores by situational and individual variables produced results indicative of a multiplicative relationship and thus supportive of theories derived from the transactional perspective.

Minority groups differ from one another, among other things, in the extent to which they are integrated into or apart from the societies to which they belong. The extent of this integration or apartness is reflected in the various ways in which the minorities differ from the rest of the population, such as in the effect of economic class upon voting. No minority group is ever completely integrated into its society, for complete integration is tantamount to the extinction of group identity. No minority group is ever completely apart, for the term "minority" implies the existence of a majority with which the minority forms a common society. The dimension of integration-apartness is related to but not identical with the dimension of assimilation. Assimilation refers to the replacement or modification of group characteristics as a consequence of out-group contacts. Integration refers to the extent a minority actually forms a part of the body politic of its society. Thus, German "non-Aryan" Christians were fully assimilated but, in the Third Reich, certainly not integrated into the German society. In general, the term "integration" is applicable at various levels of analysis. We talk of the integration of individuals into groupings, the integration of these groupings into further units, and the integration of these into larger units in turn. In the case of our study, individuals are more or less integrated into their respective minority groups, and these in turn are more or less integrated into their respective societies. We are concerned in this paper with developing a measure for the degree of integration of minority groups into their societies. The basic proposition of this paper is: The more apart a minority group is from its society, the more will it differ from that society as a whole in the effect of economic class upon voting. An analysis of the voting of two minorities in Central Europe illustrates the above proposition. This is followed by comments on minority group voting in the United States and Canada.

The article presents abstracts of various papers related to the civil and common law. One of the paper discussed is "Death by Wrongful Act in the Civil Law," issued by the Common Law Technique and Civil Law Authorities. In Panama R. R. Co. v. Rock, the U.S. Supreme Court, reversing the judgment of the Circuit Court of Appeals for the Fifth Circuit, holds that a husband cannot maintain an action for wrongfully causing the death of his wife in the Canal Zone. This proposition, sufficiently startling of itself in the year 1924, becomes more surprising when one turns to the opinion of the majority of the court and perceive its presuppositions. Another paper discussed is "Promise to Discharge Promisee's Debt to a Third Party: Effect of a Suretyship Relation Between Promisor and Promisee Upon Promisee's Rights."

The article presents information on various amendments to the Constitution of the U.S., and different laws related to searches and seizures of property and papers. The Fourth Amendment to the Constitution of the U.S. discusses about the right of people to be secure in their persons, houses, papers and effects, against unreasonable searches and seizures and issue of warrants. Constitutional provisions more or less similar to this one exist in all the states, except in New York where such a limitation appears in the Civil Rights Law. It is well known that the adoption in 1791 of the first ten amendments resulted from the agitation for a Bill of Rights which attended the ratification of the Constitution.

The article presents abstracts of various papers related to legislation of the U.S. One of the papers discussed is "The Constitutionality of the Pipe-Line Amendment." By an amendment to the Interstate Commerce Act adopted in 1906 all persons engaged in the transportation of oil by interstate pipelines are placed on the footing of common carriers. A recent decision of the Commerce Court holding this amendment invalid because it applies to pipelines, which have never professed to carry for the public, presents a constitutional question of considerable importance. Another paper discussed is "Martial Law." Military jurisdiction is of three kinds. The universal demand for security to person and property, which has everywhere, expressed itself in the form of constitutional guarantees against interference with individual rights.

This article presents a study, discusses the trends in fertility of Mexican Americans. The present paper will examine trends in Mexican American fertility in comparison to Anglo American fertility from 1950 to 1970 in the southwestern states. Attention will be devoted primarily to cumulative fertility rather than current fertility since the former measure is the only one available for all the time periods and areas studied. The principal obstacle to investigation of the dynamics of the Mexican American population is the inconsistency in definition and identification of the population over a substantial time span. The Mexican American population has been variously defined operationally by race in the 1930 Census, by Spanish mother tongue in the 1940 Census, by Spanish surname in the 1950 and 1960 Censuses, and by questions on origin or descent in the November 1969 Current Population Survey. Information compiled in the 1970 Census will allow tabulations of data according to varying combinations of mother tongue, Spanish surname and Spanish origin or descent. At the time this paper went to press, the materials published from the 1970 Census relating to the Mexican American population consisted only of data for the population of Spanish language or Spanish surname.

The paper is concerned with testing an application of a theory of investment behavior based on the neo-classical theory of optimal capital accumulation. The demand for capital is determined to maximize net worth under the neo-classical conditions of production. With the assumption of a lag in the completion of investment projects, gross investment is a distributed lag function of period-to-period changes in desired capital stock. The investment process is divided into a series of separate stages, the first stage being a change in the demand for capital services, intermediate stages being for letting contracts, and so on, and the final stage the actual investment expenditure. To extend the theory to include anticipated investment expenditures, these are treated as a special kind of intermediate stage. The purposes of the paper are to test hypotheses about the internal structure of the investment process when viewed in this way, and to investigate whether forecasting actual investment expenditures by treating the investment process in this way can improve upon the method used by the OBE-SEC. [ABSTRACT FROM AUTHOR]

The article presents information about Samuel S. Wilks, a great contributor to statistics. Wilks' behavior toward applications was peculiarly split, he encouraged his students to work on applications, not always an easy thing to do in a strongly theoretical mathematics department; he often told students about applications that he regarded as "neat" or "cute" or "clever"; the statistical colloquium he guided often had speakers on practical applications of mathematical statistics; he himself wrote some practical papers in statistics, but in the classroom he rarely discussed applications. Repeatedly, however, practical problems explicitly influenced both his own publications and those of his students and Wilks often used applications as motivation for the discussion of distribution theory, usually going well beyond the needs of the original problem. The papers to be discussed exhibit incompletely and fragmentarily a major influence on the work of the man and his students. Wilks watched the development of the statistical theory of order statistics closely. Indeed he wrote a masterful summary of the literature. The general area involves the study of the statistical properties of ordered measurements.
