Gelegenheit macht Liebe - die Wege des Kennenlernens und ihr Einfluss auf die Muster der Partnerwahl
Full text linkIn zahlreichen Studien wurde nachgewiesen, dass die Partnerwahl in der heutigen modernen Gesellschaft - auch wenn sie formal als freie Wahl angesehen wird - keineswegs zufällig ist, sondern bestimmte Muster erzeugt. In den meisten Fällen finden Partner zueinander, die sich in Bezug auf sozialstrukturell relevante Merkmale wie Herkunft, Bildung, Alter oder Konfession gleichen. Während in der Suche nach Erklärungen für die Selektivität der Partnerwahl verschiedene Theorieansätze herangezogen werden, sind die äußeren Umstände des Zusammentreffens potentieller Partner, d.h. die Frage des "wo" und des "wie", bisher kaum erforscht. Der vorliegende Beitrag untersucht vor diesem Hintergrund die Wege des Kennenlernens zukünftiger Partner, wobei die Wege durch Schule und Ausbildung, Arbeit und Beruf, Freunde und Bekannte bzw. Verwandte im Mittelpunkt stehen. Es werden Datensätze der Konstanzer Partnerwahlstudie 1992 und der Regionaluntersuchung 1996 (als Nachfolge der Erhebungen der "Kommission für die Erforschung des sozialen und politischen Wandels in den neuen Bundesländern") zugrundegelegt. Die Autoren gehen der Frage nach, inwieweit die bildungs- und die altersbezogene Partnerwahl von den Wegen des Kennenlernens beeinflusst werden. Die Bildungs- und Altersunterschiede werden ferner im Zusammenhang der Machtstruktur in der Familie und der Stellung der Frau betrachtet. Als wichtigstes Ergebnis wird festgehalten, dass Freunde und Bekannte sowie die Bildungsinstitutionen von Schule und Ausbildung seit mehr als drei Jahrzehnten die häufigsten Wege des Kennenlernens darstellen, wohingegen Verwandte nur eine sehr untergeordnete Bedeutung für die Partnerwahl haben.

The Influence of Bordetella Pertussis Vaccination of CFW Mice on Platelet Aggregation and Cyclic Amp Levels in Response to ADP, Aminophylline, Various Biogenic Amines and Prostaglandin E1
No full textThe injection of certain strains of mice and rats with living or killed Bordetella pertussis organisms is followed by altered responses of the host to various stimuli including histamine, serotonin, endotoxin, anaphylaxis and cold stress (65, 69). One of these, which has received the attention of a number of investigators, is the marked increase in histamine sensitivity that develops in pertussis-vaccinated hosts. Initially, attempts were made to define the underlying mechanism of this hyperreactive state in terms of either an increased histidine decarboxylase activity (142) or a reduced histaminase activity (66, 83). However, the proposed primary role of these enzyme malfunctions in amine sensitivity was placed in doubt by subsequent evidence (99, 141, 160).ProQuest Traditional Publishing Optio
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
