Teaching publishing in the United States     

Albert N. Greco 《Publishing Research Quarterly》1990,6(1):12-19

What must a college professor know and do in order to teach about the diverse and constantly changing publishing field? The author discusses some theoretical and practical ideas about teaching publishing, including (1) establishing an advisory board of industry leaders; (2) creating a comprehensive publishing curriculum that draws upon the academic resources of other departments and/or schools within a university; (3) recruiting, developing, and maintaining a faculty; (4) developing an effective internship and job placement program; (5) establishing and maintaining contacts with regional and national publishing trade associations; and (6) discussing the need for more scholarly studies on the eclectic international publishing industry.  相似文献   

U.S. book returns, 1984–1989     

Albert N. Greco 《Publishing Research Quarterly》1992,8(3):46-61

Between 1984 and 1989, the U.S. book industry drowned in a recorded $7.88 billion of returns: 23.87 percent of all books published during those years were returned to publishers by wholesalers and booksellers for full credit. This massive return of books undermined the stability of the book industry, causing many publishers to question the efficacy of a system that failed to operate successfully during a period of exceptionally stable business conditions, free from high rates of interest and inflation, recession, or a war. In this study the author addresses the book return phenomenon by: (1) analyzing statistics about the U.S. book industry and its twelve key market segments; (2) evaluating possible causes of the increase in returns; and (3) proposing some suggestions to reduce returns. Albert N. Greco also serves on the board of directors of the Book Industry Study Group, publisher ofBook Industry Trends, 1991.  相似文献   

The first amendment,freedom of the press,and the issue of “harm”: A conundrum for publishers     

Albert N. Greco 《Publishing Research Quarterly》1995,11(4):39-57

Does strict adherence to the principles of the First Amendment and opposition to any forms of censorship inflict “harm” on women and American society? In this article, the author surveys the published literature, U.S. Supreme Court decisions, and substantive issues raised by “tabsolutist” defenders of the First Amendment as well as by feminists opposed to pornography. He argues that the “Mill-Paul hypothesis” should be adopted by society to confront the censorship morass that has deeply divided American society. Namely, if an image or a printed work causes harm to anyone, it should be prosecuted under existing legal codes.  相似文献

Counselor educators maintain a responsibility for providing site supervisors with professional development opportunities (Council for Accreditation of Counseling and Related Educational Programs. 2009 ). The goal of this study was to evaluate a model for providing preparation to site supervisors. Significant differences were observed from pretest to posttest on the Supervisory Self‐Efficacy Scale (Johnson & Stewart, 2008 ).  相似文献   

Microfluidic impedance cytometry of tumour cells in blood     

Daniel Spencer  Veronica Hollis  Hywel Morgan 《Biomicrofluidics》2014,8(6)

The dielectric properties of tumour cells are known to differ from normal blood cells, and this difference can be exploited for label-free separation of cells. Conventional measurement techniques are slow and cannot identify rare circulating tumour cells (CTCs) in a realistic timeframe. We use high throughput single cell microfluidic impedance cytometry to measure the dielectric properties of the MCF7 tumour cell line (representative of CTCs), both as pure populations and mixed with whole blood. The data show that the MCF7 cells have a large membrane capacitance and size, enabling clear discrimination from all other leukocytes. Impedance analysis is used to follow changes in cell viability when cells are kept in suspension, a process which can be understood from modelling time-dependent changes in the dielectric properties (predominantly membrane conductivity) of the cells. Impedance cytometry is used to enumerate low numbers of MCF7 cells spiked into whole blood. Chemical lysis is commonly used to remove the abundant erythrocytes, and it is shown that this process does not alter the MCF7 cell count or change their dielectric properties. Combining impedance cytometry with magnetic bead based antibody enrichment enables MCF7 cells to be detected down to 100 MCF7 cells in 1 ml whole blood, a log 3.5 enrichment and a mean recovery of 92%. Microfluidic impedance cytometry could be easily integrated within complex cell separation systems for identification and enumeration of specific cell types, providing a fast in-line single cell characterisation method.  相似文献   

Children's Conceptions About the Origin of Species: A Study of Italian Children's Conceptions With and Without Instruction     

Anna Emilia Berti  Laura Toneatti  Veronica Rosati 《学习科学杂志》2013,22(4):506-538

Investigations of people's understanding of the evolution of species have focused mainly on secondary school and university students. Very few investigations have taken into consideration younger students, and none have related children's ideas about the origin of species to formal instruction on this topic. To help fill this gap, the present study examines the effect of this instruction in elementary school children by comparing Italian second graders (n = 21; age = 7 years, 1 month, to 8 years, 7 months) with third graders (n = 18; age = 8 years, 1 month, to 9 years, 4 months) who had been taught about “the earth before humans” for several months in keeping with the Italian National Syllabus for this grade level. Semistructured interviews were used to examine children's thoughts about speciation. The majority of second graders used a creationist framework, whereas most third graders used a mixed framework (referring to both creation and evolution) or an evolutionary framework. However, children did not know about the mechanism of evolution and considered it to be the result of the passage of time, the use and disuse of body parts, or the need to adapt to a changing environment, as suggested by their teacher and textbooks.  相似文献

Narratives of agency: the experiences of Braille literacy practitioners in the Kha Ri Gude South African Mass Literacy Campaign     

Veronica I. McKay 《International Journal of Inclusive Education》2013,17(4):435-456

In this article, we locate the Kha Ri Gude South African Mass Literacy Campaign within the context of the problem of illiteracy and exclusion in South Africa, while concentrating on various post-apartheid initiatives designed to give visually challenged adults the opportunity to become literate. We shall provide a detailed account of focus group sessions organised in 2012; the aim of these sessions was to explore the experiences of blind literacy practitioners who were charged with the supervision and coordination of Braille literacy classes for blind, illiterate adults. We suggest that the way the practitioners expressed what being involved in the Campaign meant for them for an extended period (three years or more) gives us a glimpse of how, through their roles as literacy organisers, they were able to engender agency among blind adult literacy learners and themselves.  相似文献   

Shaping the future: Mergers,acquisitions, and the U.S. publishing,communications, and mass media industries, 1990–1995     

Albert N. Greco 《Publishing Research Quarterly》1996,12(3):5-15

Between 1990 and 1995, a substantive reconfiguration took place within the publishing, communications, and mass media industries in the United States. These changes were triggered primarily by five pivotal developments: (1) the direct impact of strategic planning theories and practices on a relatively small number of U.S. and foreign media executives; (2) a dramatic technological convergence within the entire communications industry; (3) a quest to gain hegemony over the creation, production, and distribution of electronic and print information and entertainment products and services in the United States and the global marketplace; (4) a sharp increase in media usage and expenditures in the United States; and (5) the impending passage of a massive, revolutionary telecommunications bill. This legislation (the Telecommunications Act of 1996) changed drastically the ground rules created by the Communications Act of 1934, lifted restrictions on the ownership of media properties, allowed media companies to enter formerly forbidden markets, and reduced or eliminated governmental controls over the burgeoning communications business. The deeply etched lines separating “newspapers” from “books” and “magazines”, or “television” from “telephone”, “radio”, “film”, and “video” became hazy, and, in some instances, disappeared. Media scholars and industry experts realized that the communications landscape had to be viewed as a totally interconnected industry, albeit a rather diverse one.  相似文献
