Selected AbstractsTHE FACE OF MONEY: Currency, Crisis, and Remediation in Post-Suharto IndonesiaCULTURAL ANTHROPOLOGY, Issue 1 2009KAREN STRASSLER ABSTRACT In the period of transition following Suharto's resignation as president of Indonesia in 1998, the image of the 50,000Rp bill bearing his face became a visual shorthand for the corruption and abuse of power that had characterized his regime. Accessible, decentralized consumer technologies enabled people to alter money's appearance, transforming it from a fetish of the state into a malleable surface available for popular reinscription. As the medium of money was "remediated",absorbed into other media, refashioned, and circulated along new pathways,it became a means by which people engaged questions of state power, national integrity, political authenticity, and economic relations opened up by the crisis of Reformasi (Reform). The essay argues that remediations of public forms play a crucial role in times of political transition by enabling people to materialize alternative visions of political authority and authenticity. Moreover, remediated forms have become a characteristic modality of political communication in the post-Suharto period under conditions of democratization and an increasingly diversified media ecology. [source] Book and Media ReviewsADDICTION BIOLOGY, Issue 4 2000David Ball Books reviewed in this article: Book reviews in this column will primarily be of titles focusing completely, or in part, on biological aspects of addiction. However, significant titles of general relevance to the addictions field will also be included, even if they are not "biological", as will titles of general methodological and clinical relevance, even if they are not on "addictions". Similar considerations will apply to other media (software, audio tapes and CDs, videos, etc). However, specific "addictions" software applications seem to be relatively uncommon and, as these items are rarely reviewed elsewhere, we will endeavour to include reviews of some of the older programmes that are still useful, as well as new titles that appear. I would appreciate suggesti ons of any items suitable for reviews, but especially software and other media of specifi c relevance to the addictions.

S. de Lemos Convective heat-transfer coefficients in foam-like materials, modelled as an array of elliptic rods, are numerically determined. An incompressible fluid is considered, flowing through an infinite foam-like material with an arbitrary solid temperature. A repetitive cell is identified and periodic boundary conditions are applied. Turbulence is handled with both low and high Reynolds number formulations. The interfacial heat-transfer coefficient is obtained by volume integrating the distributed variables obtained within the cell. The results indicate that, for the same mass-flow rate, materials formed by elliptic rods have a lower interfacial heat-transfer coefficient compared to other media modelled as staggered arrays of square rods. [source] Influence of storage regime prior to abrasion on surface topography of restorative materialsJOURNAL OF BIOMEDICAL MATERIALS RESEARCH, Issue 2 2003Cecilia Pedroso Turssi Abstract This investigation was carried out to evaluate the effect of storage conditions prior to brushing simulation on surface texture of restorative materials. One resin-modified glass ionomer (Fuji II LC Improved/GC Corp.), one polyacid-modified composite resin (Dyract AP/Denstply), one microfill composite (Durafill VS/Kulzer), and one hybrid (Filtek,Z250/3M) composite were tested. Forty-five standardized cylindrical specimens of each material were made and randomly divided into three groups according to their subsequent storage conditions: distilled deionized water, artificial saliva, or pH-cycling regime. After 24 h, the experimental units were finished and polished and the surface roughness was measured to obtain Ra baseline values (Bv). Samples were subjected to their assigned storage regime and brushed afterwards. By the end of 10 repetitions of this protocol, final surface roughness readings (Fv) were taken. The analysis of covariance (, = 0.05), considering the covariate Bv showed a significant interaction between restorative material and storage condition (pvalue = 0.0002). Tukey's test revealed that the pH-cycling model provided a significantly lower surface roughness for Fuji II LC and Dyract AP than did the other media. For both composites no significant difference among storage regimes was detected. Under a condition simulating dynamic variation in pH prior to abrasion, the resultant surface texture may be either smoothed down or unchanged, depending on the restorative material, when compared to the effect provided by artificial saliva and distilled deionized water. © 2003 Wiley Periodicals, Inc.

Face-to-face (FtF) and telephone communication were used more frequently than written media, but all were used fairly frequently. Communication using all media was more frequent when the grandparent or grandchild initiated interaction as opposed to the parent. Relationships in which the grandparent initiated contact featured more use of written media (letters, e-mail, cards). Frequency of communication using all media was positively associated with relational quality. Telephone communication best predicted relational quality when use of other media was controlled. In this paper, I discuss implications for media richness theory, the communication predicament of aging model, and future research on grandparent-grandchild relationships. [source] Fluctuating asymmetry of sexual and nonsexual traits in stalk-eyed flies: a poor indicator of developmental stress and genetic qualityJOURNAL OF EVOLUTIONARY BIOLOGY, Issue 1 2000Bjorksten It has been proposed that females use fluctuating asymmetry (FA) in sexual ornaments to assess male quality. FA of sexual traits is predicted to show greater sensitivity to stress than FA of nonsexual traits, and to be heritable. We used a half-sib mating design and manipulation of larval food environment to test these predictions on stalk-eyed flies, Cyrtodiopsis dalmanni, in which females prefer males with larger eyespans. We measured size and FA of eyestalks and of two nonsexually selected characters, wing length and width. We found no evidence of an increase in FA under larval food stress in any of the individual traits, although trait size decreased under stress. We combined FA across traits into a single composite index, and found that males reared in the most benign larval environment had significantly higher composite FA than males reared on other media. There was no such effect in females. Heritability of FA was not significantly different from zero in any of the traits, in any of the environments, although trait sizes showed high heritability. We conclude that FA in sexual and nonsexual traits is a poor indicator of developmental stress and genetic quality. [source] Microemulsion copolymerization of styrene and acrylonitrile with n -butanol as the cosurfactantJOURNAL OF POLYMER SCIENCE (IN TWO SECTIONS), Issue 1 2005Yuanchang Shi Abstract The microemulsion copolymerization of styrene and acrylonitrile in an n -butanol/cetyltrimethylammonium bromide/oil/water microemulsion system was studied. The solubilization sites of the two monomers were determined with an NMR technique. The results showed that the solubilization behaviors of the two monomers were quite different. Most of the styrene was solubilized in the palisade layer of the microemulsion, whereas the acrylonitrile had an equilibrium distribution in the aqueous phase and palisade layer of the microemulsion. The reactivity ratios of styrene and acrylonitrile in the microemulsion system were different from those in other media. The effect of the monomer feed composition on the copolymerization kinetics was investigated, and the mechanism of nucleation of the latex particles was examined. The experimental results showed that the copolymerization loci were changed from the microemulsion droplets to the aqueous phase when the concentration of acrylonitrile in the monomer feed reached approximately 80%; this could be further proved by the effect of the monomer feed composition on the copolymerization kinetics. © 2004 Wiley Periodicals, Inc.

The perceived relative advantage of the Internet over other media is its cost-effectiveness and interactivity, which in turn contribute to its persuasive capabilities. Ironically, despite its potential, we are nowhere nearer understanding how interactivity affects processing of health information and its contribution in terms of health outcomes. An experiment was conducted to examine the effects of Web interactivity on comprehension of and attitudes towards two health Web sites, and whether individual differences might moderate such effects. Two sites on skin cancer were designed with different levels of interactivity and randomly assigned to 441 undergraduate students (aged 18,26) at a large southeastern university. The findings suggest that interactivity can significantly affect comprehension as well as attitudes towards health Web sites. The article also discusses insights into the role of interactivity on online health communications, and presents implications for the effective design of online health content. [source] Report of the Council for the session 2006,2007JOURNAL OF THE ROYAL STATISTICAL SOCIETY: SERIES A (STATISTICS IN SOCIETY), Issue 4 2007Council Report President's foreword., This year's annual report shows another very successful year for the Society. The range of the Society's new initiatives bears testament to our vigour and to the energy and enthusiasm of Fellows and staff. It is difficult to summarize all of these but I offer a brief overview of some of the highlights. This year we have awarded the first annual prize for ,Statistical excellence in journalism'. It is too easy to bemoan the general quality of coverage of statistical issues in the press and other media. But simply moaning does not improve the situation. As a positive step, on the instigation of Sheila Bird and Andrew Garratt, the Society decided to initiate an award for the best journalistic coverage of a statistical issue. This year first prize was awarded to Ben Goldacre of The Guardian. I hope that these annual awards will offer a positive focus on good coverage and help us to promote best practice. This year, also, we have set up the Professional Development Centre to act as a focus for statistical training both for statisticians and for others who use statistical methods as part of their work. It thus reflects our support for continuing professional development for our Fellows and at the same time provides outreach to members of the statistical user community who want to improve their statistical skills. We welcome Nicola Bright as the Director of the Centre and wish her every success. I am pleased to say that it is not just the Society centrally that has taken new activities this year. The Manchester Local Group have initiated a prize for final year undergraduates from any higher education institute in the north-west. At a time when there are concerns about the number of well-qualified graduates coming into the statistics profession this seems an excellent way to attract the attention of final year undergraduates. I wish this initiative every success. Another development to which the Society has contributed is the Higher Education Funding Council for England project ,more maths grads' which is designed to promote participation in undergraduate degrees in the mathematical sciences. A good supply of mathematically trained graduates is essential to the UK economy in general and to the health of the statistics discipline in particular. It is good that the Society is involved in practical developments that are aimed at increasing participation. The final new initiative that I shall draw attention to is the ,first-in-man' report which is concerned with the statistical design of drug trials aimed at testing novel treatment types. The working party was set up as a result of the adverse reactions suffered by healthy volunteers to a first-in-man trial of monoclonal antibodies and who were subsequently admitted to Northwick Park hospital. The report makes a series of recommendations about the design of such trials and will, I hope, contribute to the safety of future trials. I would like to thank Stephen Senn and the members of the working party for their considerable efforts. As well as these new initiatives there were, of course, many other continuing activities that are noteworthy. The annual conference in Belfast was a great success with many lively sessions and a good number of participants. In particular it was good to see a high number of young statisticians participating in the conference, reflecting the continuing impact of the Young Statisticians Forum on which I commented in the previous annual report. Another continuing activity for the Society is the statistical legislation going through Parliament as I write. The Society has long campaigned for legislation for official statistics. The issue now is to try to get good legislation which will have the required effect and will help the Government Statistical Service and other statistical producers to produce high quality, authoritative statistics in an environment that commands public confidence. As first published, the Society was disappointed with the Bill but we have worked to build support for amendments that, in our view, are essential. Time alone will tell how effective the final legislation will be in meeting our aims. I would like to draw attention to the success of the Membership Services team. We, although with other statistical Societies, have experienced a decline in membership in recent years but the team have turned this round. They are helping to recruit new Fellows and to retain the commitment of existing Fellows. This is a fine achievement and I would like to thank Nicola Emmerson, Ed Swires-Hennessy and the whole team. Finally we have, at last, reached a conclusion in our dealings with the Privy Council and will implement the second phase of constitutional changes. In future our business year, financial year and year for elected appointments will all coincide on a calendar year basis. There will be transitional arrangements but in due course all our administrative arrangements will coincide and will improve efficiency and co-ordination. This has been a long journey, steered effectively by our Director General, Ivor Goddard, and I congratulate him for a successful outcome on your behalf. As you read this report, I hope that you will share my impression of a Society that is lively and spawning many new programmes. We have a dual commitment: to the well-being of statistics as a discipline and to the promotion of statistical understanding and practice to the benefit of Society at large. In both respects I feel that the Society is in good health. This is due to the unstinting efforts of a large number of individual volunteers, including in particular our Honorary Officers and also, of course, the staff at Errol Street. On behalf of all Fellows, I wish to express my thanks to everyone involved. Tim Holt [source] Human and other faeces as breeding media of the trachoma vector Musca sorbensMEDICAL AND VETERINARY ENTOMOLOGY, Issue 3 2001P. M. Emerson Abstract. The fly Musca sorbens Wiedemann (Diptera: Muscidae) apparently transmits Chlamydia trachomatis, causing human trachoma. The literature indicates that M. sorbens breeds predominantly in isolated human faeces on the soil surface, but not in covered pit latrines. We sought to identify breeding media of M. sorbens in a rural Gambian village endemic for trachoma. Test breeding media were presented for oviposition on soil-filled buckets and monitored for adult emergence. Musca sorbens emerged from human (6/9 trials), calf (3/9), cow (3/9), dog (2/9) and goat (1/9) faeces, but not from horse faeces, composting kitchen scraps or a soil control (0/9 of each). After adjusting for mass of medium, the greatest number of flies emerged from human faeces (1426 flies/kg). Median time for emergence was 9 (inter quartile range = 8,9.75) days post-oviposition. Of all flies emerging from faeces 81% were M. sorbens. Male and female flies emerging from human faeces were significantly larger than those from other media, suggesting that they would be more fecund and live longer than smaller flies from other sources. Female flies caught from children's eyes were of a similar size to those from human faeces, but significantly larger than those from other media. We consider that human faeces are the best larval medium for M. sorbens, although some breeding also occurs in animal faeces. Removal of human faeces from the environment, through the provision of basic sanitation, is likely to greatly reduce fly density, eye contact and hence trachoma transmission, but if faeces of other animals are present M. sorbens will persist. [source] Development and validation of an electronic version of the Rhinoconjunctivitis Quality of Life QuestionnaireALLERGY, Issue 9 2007E. F. Juniper Background:, As clinicians and pharmaceutical companies move from paper versions of health status questionnaires to electronic versions, it cannot be assumed that adaptations to other media will produce valid data. Aims:, The aims of this study were to (1) adapt the Rhinoconjunctivitis Quality of Life Questionnaire [RQLQ(S); standardized version], for the Palm Treo 650, (2) test the device for ease and accuracy of understanding and (3) examine the validity of the electronic version by comparing it with the original paper version of the RQLQ(S). Methods:, Seventy adults with current rhinoconjunctivitis symptoms completed the electronic and paper versions of the RQLQ(S). They were randomized to complete either the paper or the electronic version first. After a 2-h break, they completed the other version. Results:, Concordance between paper and electronic versions for the overall RQLQ(S) score was acceptable with an intraclass correlation coefficient of 0.95 and there was no evidence of bias (P = 0.13). Concordance for the seven individual domains ranged from 0.86 to 0.94. A small but significant bias was observed in the activity and sleep domains (P = 0.02). Completion times were quicker with paper (4.1 vs 4.9 min, P < 0.0001). About 51% of patients preferred electronic, 17% preferred paper and 31% had no preference. Conclusions:, This electronic version of the RQLQ(S) was easy for patients to use and the concordance between paper and this version on the Palm Treo 650 provides evidence of the validity of this electronic version. [source] POTS, HOUSES AND METAL: TECHNOLOGICAL RELATIONS AT THE BRONZE AGE TELL AT SZÁZHALOMBATTA, HUNGARYOXFORD JOURNAL OF ARCHAEOLOGY, Issue 2 2006JOANNA SOFAER Summary. At the Bronze Age tell of Százhalombatta, Hungary, techniques used for making pottery echo those used in other media. Pottery and architecture have a close relationship. Not only were both made of clay, but methods of making pots echo those used for building. Similarly, pottery and metalwork share common themes and technologies for working with clay and bronze. Since choices made by potters are not solely confined to the environment, raw materials and tools, but are also socially and culturally defined, by implication the transfer of know-how must be situated within social networks between people. This paper considers how the identification of technical relationships between different media at Százhalombatta can be used to explore social relations in Bronze Age society, thereby suggesting relationships that work on both technical and social levels. [source] Regeneration potential of CIMMYT durum wheat and triticale varieties from immature embryosPLANT BREEDING, Issue 4 2001N. E. Bohorova Abstract Twenty-five durum wheat elite advanced lines and released varieties, and five triticale varieties were evaluated for their ability to produce embryogenic callus using three different media. For callus initiation and maintenance there were basal Murashige and Skoog (MS) medium containing double strains of macroelements and 2.5 mg/l 2,4D (DW1), basal MS medium containing 2.0 mg/l 2,4D (DW2), or basal MS medium supplemented with 1.0 mg/l 2,4 D and coconut milk (DW3). Plant regeneration was achieved on basal MS medium with indoleacetic acid and 6-benzylaminopurine, and plants rooted on MS with 1-naphthale-neacetic acid. DW3 medium proved better than the other media tested for embryogenic callus initiation and maintenance. Regeneration rates varied widely with both genotype and initiation medium, with values ranging from no regeneration to 100% regeneration; the plantlets produced per embryo ranged from five to 20. Fourteen of the durum wheat genotypes showed 63,100% regeneration from DW3 callus formation medium, four lines from DW1 medium, and two lines from DW2. Four of the triticale varieties had regeneration of 48,100% from DW3 medium. After six subcultures, over a 6-month period, genotypes lost their ability to regenerate plants. Only 10 lines retained some plant regeneration potential but regeneration was at reduced levels. Successful regeneration of durum wheat and triticale varieties will be used as an integral part of the transformation process. [source] Competing interests: Toronto's Chinese immigrant associations and the politics of multiculturalismPOPULATION, SPACE AND PLACE (PREVIOUSLY:-INT JOURNAL OF POPULATION GEOGRAPHY), Issue 2 2007J. Salaff Abstract Social service agencies and advocacy groups have played an integral role in mediating between the Asian ethnic populations. In the Canadian institutional setting, associations become a means of political expression. Canada incorporates new immigrants into its national institutions. However, these neo-liberal institutions and policies have not redressed major problems arising in the settlement process. Under Canada's discourse of enlightened multiculturalism, social service agencies are funded to help to integrate diverse peoples. The policy of multiculturalism meshes well with the liberal ideology underlying loose coupling, encouraging people to retain their cultural identities while settling and participating in national processes. These policies are designed to be sensitive to clients' cultural backgrounds; however, there are unforeseen consequences. In this system, different groups are granted different amounts of social, cultural and economic capital along with differential access to this capital, which affects their position and potential for action in other arenas. In particular, we find that the social service approach treats new Chinese immigrants as similar, thereby fostering competition between subgroups over leadership, funds and representation. Our data come from interviews with key figures in the Chinese-Canadian community and associations, and reviews of press and other media. Copyright © 2006 John Wiley & Sons, Ltd. [source] Geographers Mobilize: A Network-Diffusion Analysis of the Campaign to Free Ghazi-Walid Falah1ANTIPODE, Issue 2 2010Mark De Socio Abstract:, In summer 2006, Professor Ghazi-Walid Falah, a political geographer and editor-in-chief of the journal,Arab World Geographer, was arrested by Israeli police after taking photographs of rural landscapes in Northern Galilee. Falah was subsequently held for 23 days,,incommunicado,,and without charge. An international campaign to "Free Ghazi" was launched by his family, friends and colleagues, largely over academic listservs and other media. Utilizing social network analysis and contextualizing the campaign within structures of telecommunications technologies, the purpose of this paper is to assess the various factors that contributed to the campaign's coalescence, its rapid development, and its global reach. [source] Comparison of Growth and Recombinant Protein Expression in Two Different Insect Cell Lines in Attached and Suspension CultureBIOTECHNOLOGY PROGRESS, Issue 4 2001R. A. Taticek Culture conditions required for obtaining maximum recombinant protein concentrations from two cell lines, Spodoptera frugiperda (IPL,-Sf21-AE) and Trichoplusia ni (Tn 5,-1,4), were determined in this work. Conditions studied include mode of culture (suspended vs attached), agitation rates, inoculum sizes, cell concentration at the time of infection, and various serum-free media (SFM). Results were compared with the performance of attached cultures in TnM-FH with 10% fetal bovine serum. Growth rates in the different culture media tested were similar, but the cell numbers achieved (i.e., yield) improved 2 to 2.7-fold in SFM over cultures in TnM-FH. Agitation rates of 150,160 rpm were necessary for maximum growth of suspended Tn 5,-1,4 cells compared to 125,150 rpm for Sf-21 cells. An inoculum size of 5 × 105 cells/mL gave good growth rates and optimum biomass yields for both cell lines. Cultures of both cell lines were infected with viruses encoding for ,-galactosidase or human secreted alkaline phosphatase (seAP). Protein expression in TnM-FH in attached culture showed that Tn 5,-1,4 cells are 2,4.5 times more productive on a per cell basis than Sf-21 cells grown under similar conditions. Production of ,-galactosidase in Sf-21 cells increased 50% in suspension cultures with SFM compared to attached cultures in TnM-FH, but seAP expression was essentially unchanged by culture techniques. The Tn 5,-1,4 cells produced 2.6,4.4 and 2.7,3 times more ,-galactosidase and seAP, respectively, in SFM in suspension compared to Sf-21 cells. EX-CELL 401 and Sf900-II were formulated as optimized SFM for Sf cell lines. However, in Sf-21 cultures EX-CELL 400 performed better than the other two media, as it increased the ,-galactosidase yield up to 25%. Surprisingly, EX-CELL 401 was the best medium for the production of ,-galactosidase by Tn 5,-1,4 cells, resulting in 25% and 69% higher volumetric and specific yields, respectively, compared to EX-CELL 405 which was formulated for this specific cell line. These results show that even when culture media are designed for maximal growth of a specific cell line, other media may provide the best conditions for protein production. [source] | ||||||||||||||||
