A Selective Bibliography on the Evolution of CATV 1950–1970

A full bibliography on one of the most active areas of broadcasting —CATV—is long overdue. Don Le Duc originally prepared this compilation while working on his doctorate at the University of Wisconsin. It is based on an extensive clipping file collected by Kenneth Lichty of India, California, and by the author's major professor, Lawrence W. Lichty of the University of Wisconsin. Support for completing the collection came, in part, through a fellowship awarded by the Department of Communication Arts and a travel grant from the Graduate School of Arts and Sciences of the University of Wisconsin. Dr. Le Duc is a member of the State of Wisconsin and United States Supreme Court Bars, and is on the publications committee of the Federal Communications Bar Association and the communications committee of the American Bar Association. Formerly on the faculty of the University of Maryland, he will be assistant professor in the Department of Speech at the Ohio State University starting this fall.

A history of the book trade in the south

Long known as a difficult market for books, the South has become more receptive, largely through the efforts of booksellers. This article reviews the history of some of the South's book retailers and their role in their communities. The often strained relations between booksellers and publishers are discussed, including the role of the publisher's rep. The establishment of regional booksellers associations is described. The impact of wholesalers on retail business practices is reviewed, and the current state of the book trade in the South is assessed. Philip M. Pfeffer has served since 1978 as chairman of the board and chief executive officer of Ingram Distribution Group Inc. of La Vergne, Tennessee. Ingram Distribution Group Inc. is the parent company of Ingram Book Company, the world's largest wholesaler of trade books. Mr. Pfeffer also holds the position of executive vice president and is on the board of directors of Ingram Industries Inc. of Nashville, Tennessee. He holds bachelor's and master's degrees from Southern Illinois University in Carbondale.

Investigating salt decay of stone materials related to the environment,a case study in the St. James church in Liège,Belgium

Salt crystallization is recognized as a major cause of damage to porous building materials, threatening the sustainable preservation of our valuable built heritage. Unfortunately, the crystallization behavior of the detected salt mixtures is complex and not fully understood. While the deliquescence points of single salts are well documented, this is not the case for salts in a mixture where one is confronted with the presence of different cations and anions. In this paper the salt content of the murals and the limestone tracery of the main entrance porch from the sixteenth century church of St. James in Liège, Belgium is investigated and related to the climatic conditions of its environment. Concerning the salt load, the research consists of hygroscopic moisture content measurements, quantitative ion analyses, and the prediction of phase equilibria using the thermodynamic model ECOS/RUNSALT. This model can predict the salt crystallization sequences of a particular ion mixture. The output is mathematically evaluated with collected temperature and relative humidity data, which enables the calculation of the number of salt crystallization–deliquescence cycles. The results show that even small amounts of salts can cause damage over a long period of time when the environment causes frequent cycles of crystallization–deliquescence over time. It is shown how a mixture of small amounts of (double) salts, including hygroscopic ones, can have a significant effect on the decay of historic building materials in the case of daily changing climatic conditions and periods of extreme drought. As a result, the crystallization of double salts and hygroscopic salts such as calcium nitrate cannot be ignored. The scientific method and the results are described.     

三重视角下出版物鉴定的反思

为切实做好出版物鉴定工作,有必要从类型界分、行为性质、鉴定主体三重视角对出版物鉴定重新审视。发现出版物鉴定的类型界分存在漏洞,需要明确出版物鉴定的类型界分实质上是对出版物能否合理或合法存在的判断,可以考虑从“鉴定类型”到“鉴定方法”的模式转换;出版物鉴定的性质认识存有分歧,需要明确出版物鉴定的性质仍属于行政鉴定,可以考虑转变出版物鉴定意见的解读视角;出版物鉴定主体的公正性面临挑战,而出版物鉴定机构的非独立建构与公正性之间没有必然联系,可以考虑提升出版物鉴定委员会的专业化构造。     

Predicting the number of coauthors for researchers: A learning model

Predicting the number of coauthors for researchers contributes to understanding the development of team science. However, it is an elusive task due to diversity in the collaboration patterns of researchers. This study provides a learning model for the dynamics of this variable; the parameters are learned from empirical data that consist of the number of publications and the number of coauthors at given time intervals. The model is based on relationship between the annual number of new coauthors and time given an annual number of publications, the relationship between the annual number of publications and time given a historical number of publications, and Lotka's law. The assumptions of the model are validated by applying it on the high-quality dblp dataset. The effectiveness of the model is tested on the dataset by satisfactory fittings on the evolutionary trend of the number of coauthors for researchers, the distribution of this variable, and the occurrence probability of collaboration events. Due to its regression nature, the model has the potential to be extended to assess the confidence level of the prediction results and thus has applicability to other empirical research.

论宋儒疑经与文献学发展的关系

疑经是指古代儒生对儒家经籍作者和文本真实性、合理性、完整性的怀疑，往往出于经学的视角和思路，与重客观真实的文献学有交叉但并不等同。宋儒疑经尤为显豁，对宋代文献学的影响主要体现在成果、思路和发展轨迹三个方面；宋代文献学对宋儒疑经也有促进和阻碍的反作用。宋儒疑经对后世尤其是清代文献学的发展也有影响，探讨宋儒疑经与文献学发展的关系对研究传统文化有一定的启发意义。

A universal metadata system for the characterization of nanomaterials

This paper presents a detailed analysis of a newly developed system for the identification of nanomaterials and nanostructures of an arbitrary nature. The system has been created as a result of the joint work of the Committee on Data for Science and Technology (CODATA) and the International Council for Science (ICSI). It is shown that at its core the developed system is an extended set of metadata that reflect the conceptual framework of a scientific discipline. Their features include a wide coverage of the sum of the properties and characteristics, as well as the possibility of adding new headings, i.e., support for the evolution of the conceptual scheme that meets the requirements of the subject field. Limitations in the possibilities of the representation of certain categories of nanomaterials, especially of macroscopic objects, are found. It is shown that it is possible to overcome them by the active use of existing ontologies in the field of materials science.     

法律法规中档案及其属概念界定方法探讨

梳理法律法规中档案及文件、记录、数据等属概念界定的方法,认为现行《档案法》《档案法实施办法》中的档案与档案属概念及其具体所指事物之间的范围并不契合,而《〈中华人民共和国档案法〉修订草案（送审稿）》界定档案的方法较好地解决了这一问题。事实证明,法律法规中运用举例型档案概念界定方法比运用定义式档案概念界定方法更为符合立法技术规范和社会现实需要。同时,不应要求其他法律法规中的档案概念与《档案法》中的档案概念完全相同,而应采取归纳、提炼和概括的方法,使其更加符合规范对象的实际,从而不断丰富档案法律体系中档案概念的内涵。     

Conservation strategy for food-based perishable art: preservation versus reconstruction illustrated by Piece in Ghent by Jason Rhoades (1994)

The aim of this paper was to discuss the role of food preservation science and technology in the conservation of complex food-based installations. By introducing the principles of food science and food preservation into the decision-making process for the conservation of contemporary art, more insight on conservation and presentation possibilities was created. Considering the installation Piece in Ghent (P.I.G.) by Jason Rhoades, which contains French fries, the principles of food preservation science were evaluated. The preservation of the original foods was discussed against the potential of a reproduction of the foods. The context for conservation was determined by analysing the artist's intention, the production method of the artwork, and the degradation processes of the food materials. From the results obtained, guidelines to preserve the ‘original’ foods were proposed, as well as guidelines to reproduce foods that can last longer. The study demonstrated that food preservation science contributed to the development of effective strategies for the conservation of contemporary food-based art.
