The article presents abstracts of all research papers presented during a meeting held as of March 1, 1972 that focused psychophysiological issues. A study on cardiac-somatic relationships in operant and Pavlovian conditioning was conducted by researchers. Comparisons of heart rate and foot flexion responses in dogs during classical and avoidance shock conditioning revealed no difference in heart rate conditional responses during avoidance or classical conditioning. Another study conducted by researchers focused on mean rate correlates of good and poor differential eyelid conditioning. The role of orienting responses in acquiring a differential conditioned eyelid response was studied by comparing a group of good conditioners with a group of poor conditioners.

The article presents a reprint of the research paper which appeared in the Tweed Commissioners Annual Report for 1972 released in April 2, 1973. The paper reflects the results of the study on the growth of the 500 hatchery reared tagged brown trout with an average fork length of 25.0 centimeters which were released into the River Tweed, Scotland on March 29, 1972.

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 focuses on research papers of clinical psychology. It informs that the same definition of research was applied in culling these journals; papers were included in the survey if they presented systematic investigation of a specifically described group of subjects and the derivation of normative or comparative data from psychometrics, case histories, or therapeutic interviews; or analysis of administration, scoring, and interpretation of a given instrument. It further informs that it is necessary to recognize, however, that changes in editorial policy of certain of the journals have resulted in the acceptance for publication of a larger number of shorter papers.

The article presents the research paper which summarizes the major ecological effects and draws conclusions concerning weed-control which are of relevance in managing such bodies of water. It focuses on the applications, effects, and usage of the Paraquat, a poisonous yellow solid used in solution as a herbicide in the management of bodies of water.

The article presents the research paper which reflects on methods used by the Freshwater Biological Association to reduce the number of pike in Lake Windermere, England. Pikes reduced the food for the trouts, which are the most important fishes in the lake. The study found out that the long lining method caught more pikes but also eels and trout which could not be returned alive.

The article presents the program for the annual meeting of the Phycological Society of America at the Arizona State University, Tempe, Arizona. The meeting will be held from June 16-22, 1974. The chairman of the program is Norma J. Lang. A field trip is scheduled on June 15, 1974. Researchers Dean W. Blinn and Gerald W. Prescott will lead the field trip. All sessions of the program at which contributed papers are presented are joint sessions of the Phycological Society of America and the Phycological Section of the Botanical Society of America.

This article examines some theoretical aspects of information transfer and the possibility of distortion in the retransmission process in India. The data from the study demonstrate that there is cleavage in perception of innovations between change agents and their clients, especially those with whom they interact most frequently. These data support propositions derived from studies of serial transmission, suggesting that message distortion occurs. Furthermore, one can infer from these data that distortion may be most severe at an early stage in a series of transmissions and this is also consisted with much serial transmission research. The data indicate that professional change agents disagree in some important respects with their primary clientele with regard to innovations being advocated for further adoption in the study area. It is apparent from these data that any distortion which may occur in this field situation is not systematic in a particular direction. If cleavages of the kind described in the paper are more general in other planned contexts, in agriculture or family planning, or whatever the objectives of the program, then it may well be that further research on message distortion should have a high priority.

This paper presents the basics of digital logic operations, discusses the functional operation of electronic circuits which accomplish these operations and analyzes the operation of complexes of these circuits which may be used for counting, timing, and amplitude registration of the phenomena of interest in psycho-physiological research.

The article presents reports of combined Annual Meeting of Canadian Academy of Endodontics and the American Association of Endodontists. The first day of the meeting featured the research seminar. The first paper was on a study concerning "Change in Dentine Brittleness Relative to Dehydration," by Douglas Stewart and Herbert Schilder of Boston University. Again from Boston University, Herbert Schilder and Roger Czarnecki reported on a "Histological Evaluation of the Human Dental Pulp in Teeth with Varying Degrees of Periodontal Disease."

This paper describes a new equipment for investigating the density properties of minerals and rocks. A description is given of the principle and operation of a gravitation gradient tube, of density standards and of a device for the precise density determination and separation of minerals. The possibility of using the method described for geological and mineralogical studies is discussed. [ABSTRACT FROM AUTHOR]

This paper presents the main trends in epigenetic research in the U.S.S.R. in the last. years: (1) Study of epigenetic zonality in thick series of sedimentary rocks of various ages and tectonic regions, (zones of unaltered clay matrix, of altered clay matrix, of quartizitic structures and hydromica-chloritic cement, and of prick-like structures and phyllite-like schists). (2) Principals of stadial analysis and mineral indicators of different epigenetic stages (clay minerals, organic matter, zeolites, feldspars, sulfides). (3) Facies of regional epigenesis connecting the main petrographic families or unaltered terrigenic rocks (quartz sandstones with kaolinitic matrix and the same composition of associated clays, acidic arkoses with hydromicaceous clays lithoclastic sands with several matrix components and associated clays, and volcanogenic greywackes) with ’related’ facies of regional metamorphism. (4) Some practical aspects of epigenesis are: for petroleum geology: maximum depth of burial according to porosity, interruption of quartz, feldspar, sphene, epidote, carbonate, biotite, and clay mineral epigenesis by oil migration; and for ore geology: (a) initial epigenesis: ore impregnation (e.g., volkonskoite of rock fragments; (b) deep epigenesis: e.g., galena impregnations due to release of trace elements during dissolution of rock forming minerals e.g., feldspars; and (c) metagenesis: ’Alpine’ veins across and along bedding, filled, e.g., with copper ores.

The paper discusses the wing-patterns of genus undersides of the two genera in question are dealt with. The fact is that the uppersides of many exotic genera of butterflies show some singular types of the wing-patterns which are so to say super-generic as the same type may occur in several genera and vice versa one genus may show several types. On the other hand no exact dependence is established of those upperside patterns upon those of the underside. To elucidate the indicated very complicate interrelations a special extensive research is necessary which has not been done.

The article focuses on research papers related to hermaphroditism in viviparous ophiurids. The statement of researcher Wyville Thomson that the eggs and embroys of Ophiacantha vivipara Ljungman species are found lying free in the body cavity in the interbranchial spaces is, evidently, due to the fact that the bursae of Ophiurids were unknown at that time. Amphiura magellanica Ljungman is hermaphroditic. The arrangement of the gonads is quite different from that known to occur in Amphipholis squamata.

The article presents a paper-and-pencil test that could discriminate the normal from manic and depressed states, a list of items was obtained which described behavior believed to be characteristic of these states. The test was ad- ministered routinely each week to patients on a research ward concerned with the manic-depressive illness. After five months, test scores were available from 9 patients who had been judged as clinically manic and 15 who had been judged as clinically depressed for various lengths of time.

This article focuses on research done on freshwater algae as of September 1968. Man's interest in freshwater algae undoubtedly extends back to prehistoric times. Many of early researchers were remarkably accurate in recording details of structure and reproduction. In 1847, professor Jacob W. Bailey published a short paper on the freshwater algae, mostly of the Catskill Mountains. He described two species of triploceras, a freshwater algae. Three Britishers who are important in this research are researchers William West, G.S. West and Felix Fritsch. The early work of Felix Fritsch was on the algal flora and ecology of Britain, Africa and Ceylon but he soon turned to morphology.

Leeson and C.C. Wilks, "Utilization of the Mandibular Premolars of the Dog for Endodontic Research," by B.C.W. Barker and B.C. Lockett, "Pulp Lability and Repair: Effect of Restorative Procedures," by L. Zach, "Endodontic Therapy Involving a Taurodontic Tooth," by F. Widerman and T. Serene and "Apical Closure of Nonvital Teeth," by J.J. Dylewski.

The article presents information on the possibilities and limitations of cross-national and cross-regional research. In approaching cross-national and cross-regional research, the author has taken for granted the fundamental rationale of comparative study as such, and disregarded general problems of its validity. This is so, as the last Congress considered this issue, and the main points of these deliberations are on record. Instead, the author has tried to focus on more specific topics of conceptualization, methodology and organization, as they bear directly upon rural social study. Accordingly, the papers included have two major foci and fall into two groups; in each of which the author has tried to secure a discussion of both theoretical as well as applied and practical aspects. The first group, focuses on problems of the proper meaning or nature of comparative research and on the essential qualities it must have to be effective. The second group is related to problems attending the execution of comparative projects. The first of the two deals mainly with major questions of methodology: firstly, with problems of interpersonal relations, including those of political clearance, of tackling cultural variations and of stereotyping; and secondly, with technical ones, chiefly the comparability of secondary data, the utilization of and relationship to theoretical models and the standardization of field procedures.

The article presents discusses that the paper "Reliability, Chance and Fantasy in Inter-Judge Agreement Among Clinicians" published in the July 1954 issue of the periodical deserves the most careful attention from all experimenters using small sample statistical because it points up grave inadequacies which are overlooked frequently in uncritical research design. Any person with long experience with games of chance will be aware of certain vagaries in statistical tendencies, which may grossly distort the characteristics of small samples of data taken in isolation from the long-term trends of the factors under study. Every elementary textbook in statistics contains illustrations of the apparent skewing which may occur with sampling inadequacies but which are smoothed out with collection of a sufficiently large sampling of data to eliminate atypical samplings.
