AbstractBy using X-ray powder diffraction to identify the crystalline constituents of ceramics, especially porcelains, a considerable amount of information can be obtained from a very small sample. The characteristic mineral in hard-paste porcelains, stonewares and highfired earthenwares is shown to be mullite, an aluminium silicate, 3Al2O3. 2SiO2, (A.S:T.M. 15–776); where there is a high calcium content aluminium silicates may occur e.g. anorthite, CaO. Al2O3. 2SiO2, (A.S.T.M.10–379) and gehlenite 2CaO. Al2O3. SiO2, (A.S.T.M.9–216). Among the soft-paste porcelains, whitlockite, β calcium orthophosphate, Ca3(PO4)2, (A.S.T.M. 9–169), is typical of those containing bone-ash, and enstatite, magnesium meta silicate, MgO. SiO2 (A.S.T.M.7–216) is typical of those containing soapstone. The glassy-frit porcelains generally contain a calcium silicate, wollastonite or pseudowol1astonite, CaO. SiO2, (A.S.T.M.10–487 and 10–486). In addition, silica–either as α quartz or cristobalite–may occur in varying proportions in all these bodies. 相似文献

Americans are increasingly concerned about video games, presumably due to the amount and graphicness of violence they contain. Social Cognitive Theory suggests that people are more likely to imitate characters they see as attractive or similar to self. To date, however, little research has examined attributes of violent characters in video games related to this issue. This content analysis examined 10 minutes of play from 60 of the most popular video games. Adapting the coding scheme from the National Television Violence Study (Smith et al., 1998; Wilson et al., 1997, 1998), various demographic and contextual features of violent characters and violent interactions were assessed. The results show that violent game characters have attributes that are likely to increase the extent to which some players perceive them as attractive and similar. Moreover, these violent characters engage in aggression that is presented as justified or graphic. 相似文献

For the agriculturist, weather-talk performs two significant rhetorical acts that display cynicism toward nature: first, a faith in technology; and second, a conviction in the cultural myths associated with stewardship toward nature. This study explores these two themes by discussing the results of ethnographic interviews conducted with farmers. Whereas Aldo Leopold (1949) articulated a need for a moral relationship with nature, this study illustrates that contemporary weather-talk amends stewardship with rhetorical cynicism. The stewardship ethic embodied by agriculture is transcended into a cynicism whereby nature is distrusted and elusive. 相似文献

Abstract This study explores the validity of Meyer's (2004) influence model in the cable news network environment. The influence model proposes that news media organizations' profitability is linked to their societal influence, which depends on audiences' perceptions of their credibility and news quality. The results show a good fit between a structural equation model of the influence model and data from a survey probing respondents' opinions of CNN and Fox News Channel. The study also examines audience members' attitudes toward the two cable news networks and found that their opinions of CNN are significantly more positive. 相似文献

AbstractThe treatment of two silver bangles found at Rojdi and dated c. 2000 b.c. is described. The bangles were separated by removing the hard incrustations with a 20% sodium hexametaphosphate solution and 15% acetic acid. Silver chloride was removed with a 25% solution of 0.88 ammonia and a 20% aqueous solution of ammonium thiosulphate.Silver sulphide was removed in a 20% formic acid bath. Polyvinyl acetate was used for consolidation, and a coating of polymethyl methacrylate was applied. The silver was found to contain copper and lead. The causes of embrittlement and the manufacturing technique are discussed. 相似文献

HIV remains a significant health concern entering the fourth decade of the epidemic [Centers for Disease Control and Prevention. 2014. HIV basics. Retrieved from http://www.cdc.gov/hiv/basics/index.html], and people living with HIV continue to grapple with stigma. This study uses Leary and Schreindorfer's [1998. The stigmatization of HIV and AIDS: Rubbing salt in the wound. In V. J. Derlega &; A. P. Barbee (Eds.), HIV and social interaction (pp. 12–29). Thousand Oaks, CA: Sage] conceptualization of stigma to explore prior stigmatization on reasons for and against future disclosures. We interviewed HIV+ individuals (N?=?59) and used a combination of deductive and inductive coding to analyze participants’ responses. Deductive codes consisted of four stigma characteristics (pose a threat to others’ health and safety, deviate from group standards, create negative emotional reactions in others, and failure to contribute), experiences of feeling stigmatized due to HIV status (yes or no), and the degree to which HIV stigma was a concern (major, minor, or no concern). Inductive coding identified examples of perceived and experienced stigma and stigma concerns on future disclosure decision-making. Practical implications discuss individual, institutional, and societal stigma-reduction interventions and programs. 相似文献

This article documents the 30‐year history of communication network research at Michigan State University (M.S.U.), providing a case study of the evolution and diffusion of an academic innovation. Three past and continuing issues for network scholars are identified: a lack of professional reward for developing user‐friendly computer programs, unresolved methodological problems, and a need for better theoretical and conceptual frameworks. The narrative also illustrates the difficulty communication as a discipline has in impacting broader intellectual traditions. The story begins with the first doctoral dissertation (Schwartz, 1968) and the first network analysis software program in 1970 (Richards’ Negopy), continuing to the last dissertation (Susskind, 1996), and ending in 1998 when J. David Johnson left the M.S.U. faculty. Other major players in the M.S.U. network tradition included David K. Berlo, Eugene Jacobson, Everett M. Rogers, Vincent Farace, Peter Monge, and Erwin Bettinghaus. Ironically, Schwartz and Susskind met in 1998 while Schwartz was preparing to retire from Cornell University and Susskind was starting as an Assistant Professor in a different department, thus providing closure to the M.S.U. network. 相似文献

ABSTRACTWith the proliferation of free and easy-to-use tools to make online tutorials, many libraries have been creating online tutorials for their users. These cover everything from showing users how to navigate the databases to covering issues like copyright and evaluation. While the tutorials range from entertaining to rather dry, many of them, regardless of their entertainment value, do not employ the methods that can lead to deeper learning. Mayer (2014a) has explored the concepts and research around online tutorials in The Cambridge Handbook of Multimedia Learning. The principles covered in the handbook and in the related research can be quite counterintuitive for those of us who create online tutorials. This article explores these principles as they relate to tutorials created for library instruction. Additional research to expand on and support Mayer's principles will be discussed to provide evidence-based strategies for deepening learning and reducing elements that detract from learning. 相似文献

Exemplification theory (Zillmann, 1999, 2002; Zillmann &; Brosius, 2000) suggests exemplar representations in media content may cause people to make overestimated judgments about phenomena included in this content. The current study sought to examine the role telepresence plays in increasing this exemplification effect. Two-hundred and seventeen participants viewed a news story about Hurricane Katrina using one of three channels: HDTV, NTSC, or on an iPod. Data were consistent with predictions as participants who experienced greater spatial presence and perceptual realism while watching this news story reported increased judgments of the severity of hurricanes and also reported a greater likelihood to engage in behaviors associated with hurricanes. Theoretical and practical implications of these findings are discussed. 相似文献

AbstractBorobudur was constructed around 800 a.d. and abandoned in the 10th century. The history of its rediscovery in the early 19th century and subsequent restoration are discussed. An outline is given of various factors leading to the present preservation programme. The structure of the monument is described. Borobudur recalls the most elementary form of a stupa but is also a replica of the universe in Buddhist cosmology.The monument measuring 123 meters at its base is c. 31 meters high and has 504 statues and eleven series of bas-reliefs consisting of 1460 scenes; the total length of the sculptured surface is c. 3 km. The foot of the monument with the lowest series of reliefs was hidden by the ancient builders by a stone encasement. The significance and function of Borobudur are discussed from an historical point of view. 相似文献

Co-cultural theory provides a theoretical framework that examines the ways that members of co-cultural groups communicate when interacting with members of a dominant culture (Orbe, 1998a). The tenants of the theory were inductively derived via phenomenological analyses of focus group and interview data. Two of the central theoretical components, preferred outcome and communication approach, have been conceptualized as general tendencies that influence communication practices by co-cultural group members within interactions with members of dominant cultural groups. This article reports on the design of a self-report measure of these two components of co-cultural theory and provides evidence from two studies for the construct validity and reliability of the co-cultural theory scales (C-CTS). 相似文献

ABSTRACT We live in a time of great change, an increasingly global society, knitted together by pervasive communications and transportation technologies and driven by the exponential growth of new knowledge. It is a time of challenge and contradiction, as an ever-increasing human population threatens global sustainability; a global, knowledge-driven economy places a new premium on workforce skills through phenomena such as off-shoring; governments place increasing confidence in market forces to reflect public priorities even as new paradigms such as open-source technologies challenge conventional free-market philosophies; shifting geopolitical tensions driven by the great disparity in wealth and power about the globe, national security, and terrorism. (Friedman, 2005) Yet it is also a time of unusual opportunity and reason for optimism as these same technologies enable the formation of new communities and social institutions, better able to address the needs of our society. 相似文献

Female friendships are significant to many Black females because they represent a homeplace, or a safe space. This study uses Baxter and Montgomery's (1996, 1998) relational dialectics theory and Collins’ (2000) Black feminist thought to understand the interplay of contradictions in the stories that Black females tell in their friendship groups. The contradictions embedded in the stories were finances (spending/saving), language (“good”/“bad” English), appearance (satisfaction/dissatisfaction), and race (acceptance/rejection of otherness). The interaction of these tensions showed that the friends engaged in group segregation and integration, which ultimately enabled them to freely express their culturally based truths without fear of marginalization. 相似文献

Oblinger and Oblinger (2005) described the Net Generation or Net Gen, who have never known life without the Internet. They note the incremental nature of change: “One generation's technology is taken for granted by the next” (p. 2.1). In a world increasingly dominated by technology, the academic library has become a place to learn that is constantly adapting and changing, reflecting “what the student does” (Biggs, 2007). Pathfinder funding from the Higher Education Academy has enabled Bournemouth University (BU) to explore the pedagogies of learning in a hybrid environment and consider how Web 2.0 technologies within a virtual learning environment contribute to the acquisition and development of academic literacy skills. Good library design demonstrates agility and adaptability in the use of space (Heppel et al., 2004). Virtual environments enable integration of resources within the unit of study. Subject librarians, academics, and learning technologists are developing new ways of working together to deliver resources. The rate of change is exponential but is full of opportunity (“Libraries Unleashed,” 2008). In 2009 Bournemouth University will open a new library for postgraduate business students without any books, but with each student equipped with an e-book reader. This article will discuss the academic skills and learning spaces students will need to read for a degree in an environment that is predominantly electronic. 相似文献

This article extends the discussion of McDonald (2005) concerning the use of shadowing as a research technique for studying actions in organizational contexts. It addresses McDonald's observation that the few studies that refer to this technique do not make any attempt to discuss their methodological choices or their epistemological standpoints. In this paper, we intend to contribute to this emerging debate in two ways. First, we explore and discuss some contrasting applications of shadowing in the organizational literature in order to render explicit the researcher's ontological and epistemological standpoints. Second, we present our own application of shadowing starting with the redefinition of organization as a plenum of agencies (Cooren, 2006) that emerges from communication (Taylor & Van Every, 2000). Considering these theoretical grounds we propose, inspired by Latour's (2005) motto “follow the actors,” to shadow the hybrid character actions. This implies, from a methodological point of view: 1) documenting the flows that compose these actions, over the course of which a set of objects are mobilized in series of interactions, (2) applying an equivalent analytical strategy to whatever actor we are studying, and (3) grasping both the material and discursive dimension of communication as action. 相似文献
