Nutrition in pregnancy: the argument for including a source of choline
No full textSteven H Zeisel Nutrition Research Institute at Kannapolis, Department of Nutrition, University of North Carolina at Chapel Hill, Kannapolis, NC, USA Abstract: Women, during pregnancy and lactation, should eat foods that contain adequate amounts of choline. A mother delivers large amounts of choline across the placenta to the fetus, and after birth she delivers large amounts of choline in milk to the infant; this greatly increases the demand on the choline stores of the mother. Adequate intake of dietary choline may be important for optimal fetal outcome (birth defects, brain development) and for maternal liver and placental function. Diets in many low income countries and in approximately one-fourth of women in high income countries, like the United States, may be too low in choline content. Prenatal vitamin supplements do not contain an adequate source of choline. For women who do not eat foods containing milk, meat, eggs, or other choline-rich foods, a diet supplement should be considered. Keywords: pregnancy, choline, birth defects, brain development, liver function, placent
Analysis of Molar Substitution of Hydroxybutyl Group by Zeisel Reaction in Starch Ethers
No full textA new etherified starch, δ-hydroxybutyl starch (δ-HBS), was prepared by utilising 4-chlorobutan-1-ol as the etherifying reagent. The method of Zeisel gas chromatography for the determination of the molar substitution was described. This technique offers a simple and rapid method for quantitative analysis with reproducible results. Meanwhile, the mechanism of the Zeisel reaction was also investigated
Judge-Jury Agreement in Criminal Cases: A Partial Replication of Kalven and Zeisel\u27s The American Jury
No full textThis study uses a new criminal case data set to partially replicate Kalven and Zeisel\u27s classic study of judge-jury agreement. The data show essentially the same rate of judge-jury agreement as did Kalven and Zeisel for cases tried almost 50 years ago. This study also explores judge-jury agreement as a function of evidentiary strength (as reported by both judges and juries), evidentiary complexity (as reported by both judges and juries), legal complexity (as reported by judges), and locale. Regardless of which adjudicator\u27s view of evidentiary strength is used, judges tend to convict more than juries in cases of middle evidentiary strength. Judges tend to acquit more than juries in cases in which judges regard the evidence favoring the prosecution as weak. Judges tend to convict more than juries in cases in which judges regard the evidence favoring the prosecution as strong. Rates of adjudicator agreement are thus partly a function of which adjudicator\u27s view of evidentiary strength is used, a result not available to Kalven and Zeisel, who were limited to judges\u27 views of the evidence. We find little evidence that evidentiary complexity or legal complexity help explain rates of judge-jury disagreement. Rather, the data support the view that judges have a lower conviction threshold than juries. Local variation exists among the sites studied. The influences of juror race, sex, and education are also considered
Fondy kolektivního investování a ETF
No full textZeisel, J. Collective investment funds and ETFs. Bachelor thesis. Brno: Mendel Uni-versity in Brno, 2024. This bachelor thesis compares the cost of investment life insurance products with investing in ETFs. Firstly, the documents associated with each product were ana-lytically evaluated and their shortcomings were described. Then, two model examples were modeled, drawing information from the insurance modeling and investment documents. The investments were compared according to the cost impact of the investment. Finally, recommendations for investment providers we-re formulated to improve the clarity of investments for customers and recom-mendations for consumers to improve their ability to evaluate the merits of the investment on offer
L'école viennoise des recherches de motivation
No full textHans Zeisel : Die Wiener Schule der Motivforschung.
In den Jahren zwischen den Weltkriegen, unter den bedeutsamen Einfluessen jener Wiener Epoche (Вuehlег, Freud und Adler — die sozialistischen Bemuehungen um neue Lebensformen — der Wiener Kreis der Philosophen — das Beispiel amerikanischer Studien) gruendete eine Gruppe junger Akademiker und Studenten das erste Europaeische Institut fuer sozialpsychologische Studien. Von dort kam Marienthal, die erste Studie ueber die Arbeitslosigkeit, und eine Reihe neuer methodologischer Einsichten auf dem Gebiete der Motivforschung.Ганс Цейзель : Венская школа теории мотивации.
Первый в Европе институт психологических исследований был основан в междувоенные годы в Вене группой молодых ученых и студентов, использовавших исключительно благоприятную интеллектуальную обстановку, царившую тогда в столице Австрии (Бюлер, Фрейд, Адлер; усилия социалистов создать новые формы жизни; философы венской школы; пример американских исследователей). Этому Институту мы обязаны работами Мариенталя, первым опытным исследованием о безработице, а также рядом методологических достижений в области изучения мотивации.Hans Zeisel : The Vienna School of motivation research.
During the years between the world wars, a group of young scholars and students, under the unique intellectual ferment of these Vienna years (Bühler, Freud and Adler ; the socialist concern with new modes of life ; the Vienna Circle of philosophers ; the example of American research), founded the first European institute for social-psychological research. Out of it grew Marienthal, the first study of un-employment, and a number of methodological advances in motivation research.Hans Zeisel : La escuela vienese de las buscas de motivación.
El primer Institute europeo de estudios psicosociológicos fué fundado en Viena entre ambas guerras por un grupo de jóvenes universitarios y estudiantes que habían aprovechado el ambiante intelectual excepcional que caracterizaba Viena en aquella época (Bühler, Freud, Adler ; las preocupaciones de los socialistes para crear formas nue vas de vida ; filosofos de la escuela vienesa ; el ejemplo de los trabajos americanos). A ese instituto se debe Marienthal, la primera investigación empírica sobre el paro forzoso, tal como una serie de progresos metodológicos en el dominio de los estudios de motivaciones.Zeisel Hans.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Non-Coding RNAs and Hepatitis C Virus-Induced Hepatocellular Carcinoma
No full textHepatitis C virus (HCV) infection is a worldwide health problem and is one of the main causes of chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma (HCC). Despite recent improvements, effective treatments for HCC are still missing and new tools for early detection are needed. Non-coding RNAs (ncRNAs) have emerged as important regulators of gene expression and key players in human carcinogenesis, including HCC. Aberrant expression of ncRNAs is associated with HCC metastasis, invasion, dissemination, and recurrence. This review will focus on the recent advances in ncRNA expression profiles, their dysregulation in HCV-related HCC, and the clinical perspective of ncRNA signatures for the early detection of HCC
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
