    Vegetables and fruits are an important part of a healthy food diet, however, the eco-sustainability of the production of these can still be significantly improved. European farmers and consumers spend an estimated €15.5 billion per year on inorganic fertilizers and the production of N-fertilizers results in a high carbon footprint. We investigated if fertilizer type and medium constituents determine microbial nitrogen conversions in organic growing media and can be used as a next step towards a more sustainable horticulture. We demonstrated that growing media constituents showed differences in urea hydrolysis, ammonia and nitrite oxidation and in carbon dioxide respiration rate. Interestingly, mixing of the growing media constituents resulted in a stimulation of the function of the microorganisms. The use of organic fertilizer resulted in an increase in amoA gene copy number by factor 100 compared to inorganic fertilizers. Our results support our hypothesis that the activity of the functional microbial community with respect to nitrogen turnover in an organic growing medium can be improved by selecting and mixing the appropriate growing media components with each other. These findings contribute to the understanding of the functional microbial community in growing media and its potential role towards a more responsible horticulture. © 2016 The Authors.

    Full Text Available Due to globalization new media strongly impacts organizations and management approaches. Access to social media platforms, open source movement, online collaboration, rapid communication and increasing power of consumers push hierarchical organization towards flexibility and adaptability. New media offers a wide range of channels for information on competitors, for brand promotion and to new markets. But competitors have also access to the same instruments. Globalization in terms of communication on collaborative platforms, determines organizations to adopt cross-cultural and cross-organizational approaches to ensure sending the right message to the right market at the right time. Maintaining organization globally competitive implies top human resources with a trans-disciplinary background and knowledge of using the new media infrastructure sustained by a right organizational structure. This paper aims at demonstrating, with some examples too, how new media is leading decision making process to a new level for protecting organization’s image setting new norms and principles for organization and people in order to achieve best results.

    Uranyl peroxide capsules are a recent addition to polyoxometalate (POM) chemistry. Ten years of development has ensued only in water, while transition metal POMs are commonly exploited in aqueous and organic media, controlled by counterions or ligation to render the clusters hydrophilic or hydrophobic. Here, new uranyl POM behavior is recognized in organic media, including (1) stabilization and immobilization of encapsulated hydrophilic countercations, identified by Li nuclear magnetic resonance (NMR) spectroscopy, (2) formation of new cluster species upon phase transfer, (3) extraction of uranyl clusters from different starting materials including simulated spent nuclear fuel, (4) selective phase transfer of one cluster type from a mixture, and (5) phase transfer of clusters from both acidic and alkaline media. The capsule morphology of the uranyl POMs renders accurate characterization by X-ray scattering, including the distinction of geometrically similar clusters. Compositional analysis of the aqueous phase post-extraction provided a quantitative determination of the ion exchange process that enables transfer of the clusters into the organic phase. Preferential partitioning of uranyl POMs into organic media presents new frontiers in metal ion behavior and chemical reactions in the confined space of the cluster capsules in hydrophobic media, as well as the reactivity of clusters at the organic/aqueous interface.

    Social Media studies tend to focus on either internal (Friedl & Verčič, 2011; Huang et al, 2013) or external communication (Briones et al, 2011; Hanna et al, 2011; Saschi, 2012; Byrd, 2012; Kilgour et al, 2015) , rather than addressing social media across the organization. This is problematic...... because of the diversity in perspectives about how social media should be deployed among competing department perspectives in an organization are generally not explicitly considered when internal and external communication are dealt with separately.

    Full Text Available Organizations with activities of all kinds are influenced by environmental conditions, and external environment is in fact the beginning point of the strategy. Strategic management is an approach resulting from fast changing age and can consider it as a view and a technique for flexible planning to fast changes, and balanced score card is regarded as one of the strong instruments in this zone. Balanced score card can truly plays an important role in all stages of strategic management and the efficiency of this model is considerably regarded in management performance evaluation in different organizations. However, strong instrument such as balance score card is hardly used because of long term dominance of political approaches in the management of Iran media organizations. This paper conceptualizes administrational trend of strategic planning by implementing balanced score card and we draw strategy map and determine performance indexes in a written media organization (Hamshahri Newspaper.

    Contrary to TV programs projecting awareness about organ donation in society, concrete evidence exists about adverse influence of negative broadcasts on organ donation rates. We sought to determine the effect of mass media on public opinion toward organ donation and the efficacy of public campaigns and novel social media attempts on donation rates. We conducted a systematic review of relevant literature and national campaign results. Hoaxes about brain death and organ transplantation adversely affect organ donation rates in both Western and Eastern societies. Scientifically controversial and exaggerated press conferences and institutional advertisements create mistrust in doctors, thus reducing organ donation. The overall effect of public education campaigns in promoting organ donation is a temporary 5% gain. Increments in organ donation rates is expected with novel applications of social media (Facebook effect). Communication, based on mutual trust, must be established between medicine and the media. Continuing education programs with regard to public awareness on organ donation should be conducted over social media. Copyright © 2015 Elsevier Inc. All rights reserved.

    Mass media campaigns are widely and successfully used to change health decisions and behaviors for better or for worse in society. In the United States, media campaigns have been launched at local offices of the states' department of motor vehicles to promote citizens' willingness to organ donation and donor registration. We analyze interventional studies of multimedia communication campaigns to encourage organ-donor registration at local offices of states' department of motor vehicles. The media campaigns include the use of multifaceted communication tools and provide training to desk clerks in the use of scripted messages for the purpose of optimizing enrollment in organ-donor registries. Scripted messages are communicated to customers through mass audiovisual entertainment media, print materials and interpersonal interaction at the offices of departments of motor vehicles. These campaigns give rise to three serious concerns: (1) bias in communicating information with scripted messages without verification of the scientific accuracy of information, (2) the provision of misinformation to future donors that may result in them suffering unintended consequences from consenting to medical procedures before death (e.g, organ preservation and suitability for transplantation), and (3) the unmanaged conflict of interests for organizations charged with implementing these campaigns, (i.e, dual advocacy for transplant recipients and donors). We conclude the following: (1) media campaigns about healthcare should communicate accurate information to the general public and disclose factual materials with the least amount of bias; (2) conflicting interests in media campaigns should be managed with full public transparency; (3) media campaigns should disclose the practical implications of procurement as well as acknowledge the medical, legal, and religious controversies of determining death in organ donation; (4) organ-donor registration must satisfy the criteria of informed

    Organ transplantation is the optimal treatment for end-stage organ diseases. The demand for organs has exceeded the available supply, which becomes a major obstacle worldwide. Identifying the factors affecting this gap will help in overcoming this obstacle. The purpose of the work was to study the knowledge, attitudes, and beliefs of organ donation and to determine the knowledge of brain death among social media users. A cross-sectional study was conducted among social media users living in Saudi Arabia. A pre-designed self-administrated questionnaire was distributed online randomly on social media networks in 2015. Of the total 1368 participants, only 913 met the criteria. Most respondents were between 18 and 29 years of age (61.2%) and living in the central region of Saudi Arabia (64.5%). The majority of respondents received their information from television (57%) and social media (50%) networks; 46.4% of respondents knew that the religious fatwa allowed organ donation; 51% of respondents were willing to donate their organs; 46.5% considered the brain-dead to be deceased, whereas 37.7% considered it a coma; 33.3% did not know if someone who was brain-dead would ever wake up; on the other hand, 323 (35.4%) said yes. Our study showed that the vast majority of our sample had enough information about organ donation. On the contrary, they had minimal knowledge about brain death. Moreover, a fair percentage of the participants had positive attitudes toward organ donation. Also, the media had a significant effect on the information about organ donation and brain death.

    2013-11-01

    We respond to Morgan and Feeley's critique on our article "Mass Media in Organ Donation: Managing Conflicting Messages and Interests." We noted that Morgan and Feeley agree with the position that the primary aims of media campaigns are: "to educate the general public about organ donation process" and "help individuals make informed decisions" about organ donation. For those reasons, the educational messages in media campaigns should not be restricted to "information from pilot work or focus groups" but should include evidence-based facts resulting from a comprehensive literature research. We consider the controversial aspects about organ donation to be relevant, if not necessary, educational materials that must be disclosed in media campaigns to comply with the legal and moral requirements of informed consent. With that perspective in mind, we address the validity of Morgan and Feeley's claim that media campaigns have no need for informing the public about the controversial nature of death determination in organ donation. Scientific evidence has proven that the criteria for death determination are inconsistent with the Uniform Determination of Death Act and therefore potentially harmful to donors. The decision by campaign designers to use the statutory definition of death without disclosing the current controversies surrounding that definition does not contribute to improved informed decision making. We argue that if Morgan and Feeley accept the important role of media campaigns to enhance informed decision making, then critical controversies should be disclosed. In support of that premise, we will outline: (1) the wide-spread scientific challenges to brain death as a concept of death; (2) the influence of the donor registry and team-huddling on the medical care of potential donors; (3) the use of authorization rather than informed consent for donor registration; (4) the contemporary religious controversy; and (5) the effects of training desk clerks as organ

    Weak complexes between pentavalent and hexavalent actinyl cations have been reported to exist in acidic, non-complexing high ionic strength aqueous media. Such ''cation-cation complexes'' were first identified in the context of actinide-actinide redox reactions in acidic aqueous media relevant to solvent extraction-based separation systems, hence their characterization is of potential interest for advanced nuclear fuel reprocessing. This chemistry could be relevant to efforts to develop advanced actinide separations based on the upper oxidation states of americium, which are of current interest. In the present study, the chemical behavior of pentavalent uranyl was examined in non-aqueous, aprotic polar organic solvents (propylene carbonate and acetonitrile) to determine whether UO{sub 2}{sup +} cations generated at the reducing working electrode surface would interact with the UO{sub 2}{sup 2+} cations in the bulk phase to form cation-cation complexes in such media. In magnesium perchlorate media, the electrolyte adsorbed onto the working electrode surface and interfered with the uranyl reduction/diffusion process through an ECE (electron transfer/chemical reaction/electron transfer) mechanism. In parallel studies of uranyl redox behavior in tetrabutylammonium hexafluorophosphate solutions, an EC (electron transfer/chemical reaction) mechanism was observed in the cyclic voltammograms. Ultimately, no conclusive electrochemical evidence demonstrated uranyl cation-cation interactions in the non-aqueous, aprotic polar organic solvent solutions, though the results reported do not completely rule out the presence of UO{sub 2}{sup +}.UO{sub 2}{sup 2+} complexes.

    Highlights: • A crosslinked plastic scintillatior for radioactivity measurement was developed. • The effect of C-PS composition in the detection efficiency was evaluated. • C-PS permits the measurement of radioactivity in organic and aggressive media. • C-PS exhibits high detection efficiency in water and even higher in organic media. • C-PS exhibits good reproducibility under different polymerisations with elevated yield. - Abstract: The measurement of radioactive solutions containing organic or aggressive media may cause stability problems in liquid and plastic scintillation (PS) techniques. In the case of PS, this can be overcome by adding a crosslinker to the polymer structure. The objectives of this study are to synthesise a suitable crosslinked plastic scintillator (C-PS) for radioactivity determination in organic and aggressive media. The results indicated that an increase in the crosslinker content reduces the detection efficiency and a more flexible crosslinker yields higher detection efficiency. For the polymer composition studied, 2,5-diphenyloxazole (PPO) is the most adequate fluorescent solute and an increase in its concentration causes little change in the detection efficiency. The inclusion of a secondary fluorescent solute 1,4-bis-2-(5-phenyloxazolyl) benzene (POPOP) improves the C-PS radiometrical characteristics. For the final composition chosen, the synthesis of the C-PS exhibits good reproducibility with elevated yield. The obtained C-PS also displays high stability in different organic (toluene, hydrotreated vegetable oil (HVO) and methanol) and aggressive media (hydrochloric acid, nitric acid and hydrogen peroxide). Finally, the C-PS exhibits high detection efficiency both in water and in aggressive media and can also be applied in organic media showing similar or even higher detection efficiency values

  19. Cultural carrying capacity: Organ donation advocacy, discursive framing, and social media engagement.

    2016-09-01

    Social media sites such as Facebook have become a powerful tool for public health outreach because they enable advocacy organizations to influence the rapidly increasing number of people who frequent these forums. Yet the very open-ness of social media sites creates fierce competition for public attention. The vast majority of social media messages provoke little or no reaction because of the sheer volume of information that confronts the typical social media user each day. In this article, I present a theory of the "cultural carrying capacity" of social media messaging campaigns. I argue that advocacy organizations inspire more endorsements, comments, and shares by social media users if they diversify the discursive content of their messages. Yet too much diversification creates large, disconnected audiences that lack the sense of shared purpose necessary to sustain an online movement. To evaluate this theory, I created a Facebook application that collects social media posts produced by forty-two organ donation advocacy organizations over 1.5 years, as well as supplemental information about the organization, its audience, and the broader social context in which they interact. Time series models provide strong evidence for my theory net of demographic characteristics of social media users, the resources and tactics of each organization, and broader external factors. I conclude by discussing the implications of these findings for public health, cultural sociology, and the nascent field of computational social science. Copyright © 2016 Elsevier Ltd.

    Efforts to promote organ donation have traditionally relied on mass-mediated or interpersonal communication to promote donor registration. Despite its popularity, the use of online media has yet to be carefully evaluated as a platform to promote organ donation. To describe results of an intervention to promote donor registration that relies solely on online media to communicate to target audiences. For 3 years, 6 campaigns were implemented in 3 different online media formats. Online media formats included (1) traditional online advertising, (2) student seeders' social networking sites campaigns, and (3) challenge campaigns. Online media campaigns primarily targeted college-aged individuals.Intervention-Each campaign directed individuals to the dedicated project website, where they could access educational material about donation and request a donor registration card. Unique website visitors, webpages viewed per site visit, time spent on site, and organ donor cards requested/received were tracked in relation to each online media format. Traditional online advertising offered greater message exposure but failed to result in a higher proportion of website visitors who registered their donation intentions. Use of student seeders (ie, motivated students who promote donation by using social networking sites) and challenge campaigns resulted in greater attention to the project website, donor card requests, and subsequent returns. Additional research is recommended to reveal the effect of combining 2 or more varying online media formats within a single campaign.

    Full Text Available This article outlines an analysis of the ethical organization of digital media and social and individual space in everyday life. This is made from a perspective of an ‘ethics of the ordinary’, highlighting the mundane negotiations and practices conducted to maintain a ‘good life’ with the media. The analysis shows a sensorial organization of space is conducted in relation to social space, as well as individually. The interviewees use facilities provided by media technologies in order to organize space, as well as organize their media devices spatially in order to construct space for specific purposes, and maintain a good life. These results call for a deepened analysis of the sensorial dimensions of everyday space, in order to understand the ethical struggles of a life with digital media. It is important to include the full spectrum of sensorial experiences in our approach to everyday life and to take the sensorial experiences of ordinary media users into account in our analysis of space as part of an everyday ethics.

    The analysis of approaches to modeling of vibrational processing by granulated media is carried out. The vibroprocessing model which provides effective finishing of the surfaces of the parts due to the stone fruit organic media granules is developed. The model is based on the granule flow energy impact on the surface being treated. As the main characteristic of the organic media processing, a specific volumetric metal scrap is used, the physical meaning of which is the increase rate in the thickness of the material removed from the surface at a given velocity and pressure of the medium. It is shown that the metal scrap depends on the medium flow velocity, the height of the loading column of the granular medium, and the conditions for the formation of a medium stationary circulation motion. Based on the analysis of the results of experimental studies of the influence of amplitude-frequency characteristics on the removal of metal in the process of vibroprocessing with abrasive granules, the dependence of the specific volume metal removal is proposed for organic media processing, taking into account the threshold amplitude and frequency of oscillations of the working chamber, at which the effect of surface treatment is observed. The established set of relationships describing the effective conditions for vibroprocessing with stone organic media was obtained using experimental data, which allows us to assume that the model obtained is valid.

    As the organ shortage continues to grow, the creation of social media communities by transplant hospitals and the public is rapidly expanding to increase the number of living donors. Social media communities are arranged in myriad ways and without standardization, raising concerns about transplant candidates' and potential donors' autonomy and quality of care. Social media communities magnify and modify extant ethical issues in deceased and living donation related to privacy, confidentiality, professionalism, and informed consent, and increase the potential for undue influence and coercion for potential donors and transplant candidates. Currently, no national ethical guidelines have been developed in the United States regarding the use of social media to foster organ transplantation. We provide an ethical framework to guide transplant stakeholders in using social media for public and patient communication about transplantation and living donation, and offer recommendations for transplant clinical practice and future research. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Full Text Available Despite the increasing and ubiquitous use of social media for business activities, scholar research on social media marketing strategy is scant and companies deploy their social media marketing strategies guided by intuition or trial and error. This study proposes a comprehensive framework that identifies and classifies social media marketing strategic actions. The conceptual framework covers actions that support both transactional and relationship marketing. This research also positions social media marketing strategy and strategic actions in the context of the marketing organization theory, and discusses the impact of the incorporation of social media on the concept of marketing organization. The study offers valuable theoretical insight on social media marketing actions and the deployment of social media marketing strategies in companies. The investigation also provides hints about how to maximize the benefits from social media marketing for customer-oriented, market-driven organizations.

    2018-02-15

    Despite the increasing prevalence of social media usage, the activity of dermatology journals and professional and patient-centered organizations on top social media platforms has not been investigated since 2012. We investigated a total of 124 dermatology journals, 242 professional organizations, and 78 patient-centered organizations to assess their presence and popularity on social media. Searches were conducted to identify journals and organizations on Facebook and Twitter. Similar searches were done for organizations on LinkedIn. The number of Facebook likes, Twitter followers, and LinkedIn followers of the dermatological entities were quantified. There were 22 (17.7%) dermatology journals active on Facebook and 21 (16.9%) on Twitter. Amongst the professional organizations, 114 (47.1%) were on Facebook, 69 (28.5%) on Twitter, and 50 (20.7%) on LinkedIn. In comparison, 68 (87.2%) patient-centered organizations were on Facebook, 56 (71.8%) on Twitter, and 56 (71.8%) on LinkedIn. Our results demonstrate that the popularity of dermatology journals and professional and patient-centered organizations on top social networking sites has grown markedly since 2012. Although the number of dermatology journals on social media has increased since 2012, their presence continues to trail behind professional and patient-centered dermatological organizations, suggesting underutilization of a valuable resource.

  9. Empathy, social media, and directed altruistic living organ donation.

    In this article we explore some of the ethical dimensions of using social media to increase the number of living kidney donors. Social media provides a platform for changing non-identifiable 'statistical victims' into 'real people' with whom we can identify and feel empathy: the so-called 'identifiable victim effect', which prompts charitable action. We examine three approaches to promoting kidney donation using social media which could take advantages of the identifiable victim effect: (a) institutionally organized campaigns based on historical cases aimed at promoting non-directed altruistic donation; (b) personal case-based campaigns organized by individuals aimed at promoting themselves/or someone with whom they are in a relationship as a recipient of directed donation; (c) institutionally organized personal case-based campaigns aimed at promoting specific recipients for directed donation. We will highlight the key ethical issues raised by these approaches, and will argue that the third option, despite raising ethical concerns, is preferable to the other two. © 2018 The Authors Bioethics Published by John Wiley & Sons Ltd.

    Full Text Available The article is devoted to the social media analysis, as an important tool of the mass media in the youth non-governmental organizations activity. The article is about special popularity of social media among youth because of the rapid information technologies development. The author emphasizes that social media is a main online channel of communication among young generation, that should be taken into the consideration during the external communication creation. Youth organizations often use social media for target audience involvement, information dissimilation and exchange, service promotion and online dialogue. The author analyses different social media tools, such as: blogs, microblogs (Twitter, social networking sites (Facebook, VKontakte, video-sharing websites (YouTube and others. All these tools are easy in use, do not need any special skills and resources, they are low-cost as well. The author considers that it would be useful to include the organization’s Internet addresses on all social media websites and in traditional media publications, to make it as easy as possible for customers to find the youth non-governmental organizations they are looking for among the broad range of social media communities and services.

    This report focuses on the University of Wisconsin Hospital and Clinics organ procurement organization's efforts to increase deceased organ and tissue donation by using social media and personalized messages targeting members of university student organizations, their families, and their friends. A grant from the US Department of Health and Human Services funded a 2-year study to (1) identify barriers/opportunities for increasing awareness, attitudes, and behaviors related to organ and tissue donation; (2) implement an intervention using social media and personalized message to increase knowledge, support, and donor registrations; (3) measure impact on awareness and attitudinal and behavioral changes within the organization; and (4) assess behavioral measures across a host of social media analytics and organ donor registrations. The results show increases in knowledge about and support for organ donation, including a 20% increase in donor registration. As a result, funding was secured to continue the project for an additional 2 years.

    Community-based organizations (CBOs) are critical channels for the delivery of health promotion programs. Much of their influence comes from the relationships they have with community members and other key stakeholders and they may be able to harness the power of social media tools to develop and maintain these relationships. There are limited data describing if and how CBOs are using social media. This study assesses the extent to which CBOs engaged in health promotion use popular social media channels, the types of content typically shared, and the extent to which the interactive aspects of social media tools are utilized. We assessed the social media presence and patterns of usage of CBOs engaged in health promotion in Boston, Lawrence, and Worcester, Massachusetts. We coded content on three popular channels: Facebook, Twitter, and YouTube. We used content analysis techniques to quantitatively summarize posts, tweets, and videos on these channels, respectively. For each organization, we coded all content put forth by the CBO on the three channels in a 30-day window. Two coders were trained and conducted the coding. Data were collected between November 2011 and January 2012. A total of 166 organizations were included in our census. We found that 42% of organizations used at least one of the channels of interest. Across the three channels, organization promotion was the most common theme for content (66% of posts, 63% of tweets, and 93% of videos included this content). Most organizations updated Facebook and Twitter content at rates close to recommended frequencies. We found limited interaction/engagement with audience members. Much of the use of social media tools appeared to be uni-directional, a flow of information from the organization to the audience. By better leveraging opportunities for interaction and user engagement, these organizations can reap greater benefits from the non-trivial investment required to use social media well. Future research should

    The use of various contrast media is essential for examination of the pelvis with computed tomography (CT) because there is little fat between the organs and structures and because bowel may be misinterpreted as mass. Routine opacification of the distal small bowel and colon is achieved using dilute oral and rectal contrast medium, and all patients are scanned with a full bladder. A tampon is used to outline the vaginal vault. Intravenous contrast medium may be required to opacify the urinary tract or to distinguish vessels from a suspected space-occupying lesion. Pelvic masses may show tissue enhancement following injection of intravenous contrast medium but further studies are required to determine the diagnostic value of the information obtained. (Auth.)

    2017-09-08

    Social media hold enormous potentials as a communication tool for health care due to its interactive nature. However, prior research mainly focused on contingency interactivity of social media, by examining messages sent from health care organizations to audiences, while little is known about functional interactivity, which refers to social media's presence of functions for facilitating communication between users and its interface. That is, how health care organizations use interactive features on social media to communicate with the public. Thus, with a general basis of the functional interactivity framework proposed by Waters et al. (Engaging stakeholders through social networking: how nonprofit organizations are using Facebook. Pub Relat Rev 2009;35:102-106), the current study investigated three aspects of functional interactivity in microblogging, and its subsequent effects. Specifically, this study analyzed 500 Chinese hospitals' profiles on Sina Weibo, the most popular microblogging platform in China. The results showed that the most common functional interactivity feature was organization disclosure, followed by information dissemination, and audience involvement. These interactive features all positively predicted the number of followers. Also, Chinese private hospitals scored significantly higher than public hospitals to use interactive features offered by social media. The findings of this study provide important implications for health care organizations to understand new communicative functions available on social media, incorporate more functions into their profiles and thus provide audiences with greater opportunity to interact with them via social media. © The Author 2017.

    Full Text Available L'environnement naturel des enzymes étant de nature aqueuse, leurs applications industrielles se sont en général limitées à des réactions mettant en jeu des substrats solubles dans l'eau. Depuis quelques années, la possibilité de faire fonctionner des enzymes dans des milieux hydrophobes (hydrocarbures, solvants organiques a été mise en évidence, engendrant ainsi de nombreux travaux visant, d'une part à mieux comprendre les mécanismes permettant aux enzymes de rester actives dans un tel environnement et, d'autre part à explorer les nouvelles applications envisageables. Les produits pétroliers constituant par excellence le domaine des molécules hydrophobes, le présent article se propose de faire le point sur ces deux aspects, compréhension et intérêt de la catalyse enzymatique en milieu organique. Nous détaillerons ainsi les vues actuelles sur le fonctionnement des enzymes dans des solvants organiques, les différents modes de mise en oeuvre possibles et, à travers une revue de leurs applications potentielles, les principaux systèmes enzymatiques utilisés. The extension of enzymatic catalysis, classically carried out in aqueous media, to organic media can be first ascribed to the possibility of using substrates that are poorly soluble or insoluble in water. In biphasic media consisting of an aqueous phase containing the enzyme in solution and of a non water-miscible organic solvent, the enzyme is kept in a suitable aqueous environment. A variant biphasic system consists in creating reverse micelles by the addition of a surfactant in order to increase the interfacial area and thus to improve the transfers between the aqueous phase where the enzyme is located and the organic phase. In these two cases, the partition coefficient of the different reactants plays a crucial role by governing the rates and yields of reaction. Microaqueous media constitute a new system for biocatalysis in organic media. In this case, a solid enzyme

    Full Text Available The subject of this research is how spokespersons can be used in campaigns of non-profit organizations, with a goal to increase their visibility and gain public support. Namely, many companies employ celebrities for their media campaigns as protagonists and promoters of brand values. With their appearance and engagement, celebrities transfer part of their image and credibility to the brand, which widens and enriches the field of associations which brands trigger in consumers' conscience. Non-profit organizations could get similar benefits out of these campaigns. In a society where there is a certain level of fascination with celebrities, i.e. celebrity culture, their influence can be used not only to attract attention to the goods, but also to ideas. The goal of the paper is to show how spokespersons can influence behavior and attitudes of the public by participating in media campaigns, and also the important aspects of choosing a spokesperson. The paper is supposed to be a starting point for practitioners,so they can design creative ideas based on this technique on the non-profit organizations market, especially in Serbia.

    Full Text Available Despite the emergence of social media in many aspects of Vietnamese lives, including marketing and promotional activities, Vietnamese organizations have used little social media in their crisis communication efforts. The organizations are hesitant to adopt social media in crisis communication and prefer to use traditional media because of its controllability and professionalism. However, with the increasing number of organizational crises that started on social media in the past years, it is arguably that Vietnamese stakeholders use social media as one of their main communication channels during crises. Should the organizations use social media in response? Through a series of interviews to PR practitioners and stakeholders in Vietnam, this research aims to find out the similarities and gaps in the perception of social media use for crisis communication between these two groups, and to guide a crisis communication practice that is appreciated by stakeholders.   Bahasa Indonesia Abstrak: Meskipun munculnya media sosial dalam banyak aspek kehidupan Vietnam, termasuk kegiatan pemasaran dan promosi, organisasi Vietnam telah menggunakan sedikit media sosial dalam upaya komunikasi krisis mereka.

    The diffusion coefficient is one of the parameters necessary for the obtention of the extraction exponential coefficients, that are contained within the H.T.U. (height of transfer unity) calculation expression, when operating with continuous organic phase. The organic phase used was tri-n-butyl-phosphate (TBP) and varsol in the 35% and 65% proportions respectively. After each experiment, the uranium content present in each compartment was spectrophotometrically determined and the quantities contained in the aqueous phases were determined by means of volumetric titration. It was found out that the uranyl ion diffusion coefficient is two and one half times less in organic phase, this just being attributed to the greater interactions of the uranyl ions in organic than in aqueous medium

    To examine the use and impact of social media on 2-way communication between consumers and public organizations in the food safety and nutrition area. In-depth qualitative study conducted between October, 2012 and January, 2013, using semi-structured interviews in the United Kingdom and Ireland. Sixteen professionals worked on the public interface within 5 national organizations with a role in communicating on food safety and nutrition issues in this thematic analysis. Five main themes were identified: gradual shift toward social media-based queries and complaints; challenges and limitations of social media to deal with queries and complaints; benefits of using social media in query and complaint services; content redesign driven by social media use; and using social media to learn more about consumers. Social media penetrated and brought new opportunities to food organizations' interactions with the public. Given the increasing use of social media by the public, food organizations need to explore such new opportunities for communication and research.

    Social media sites are rapidly becoming one of the most important forums for public deliberation about advocacy issues. However, social scientists have not explained why some advocacy organizations produce social media messages that inspire far-ranging conversation among social media users, whereas the vast majority of them receive little or no attention. I argue that advocacy organizations are more likely to inspire comments from new social media audiences if they create "cultural bridges," or produce messages that combine conversational themes within an advocacy field that are seldom discussed together. I use natural language processing, network analysis, and a social media application to analyze how cultural bridges shaped public discourse about autism spectrum disorders on Facebook over the course of 1.5 years, controlling for various characteristics of advocacy organizations, their social media audiences, and the broader social context in which they interact. I show that organizations that create substantial cultural bridges provoke 2.52 times more comments about their messages from new social media users than those that do not, controlling for these factors. This study thus offers a theory of cultural messaging and public deliberation and computational techniques for text analysis and application-based survey research.

    1987-01-01

    Effect of organic solvents (ethanol, acetone, acetonitrile) on change in kinetic parameters of the anion exchange process (anion-exchange column chromatography) of r.e.e. (europium and gadolinium) in complexing nitric acid media has been studied. It is established that complex LnA 4 anion is the only sorbing form of europium and gadolinium on anionite. When the organic component content of the solution being the same, the dynamic parameters of lanthanide exchange have higher values in aqueous-acetonitrile and aqueous-acetone media in comparison with aqueous-enthanol solutions of nitric acid. Lesser mobility of complex lanthanide anions in aqueous-alcoholic solutions can be explained by stronger solvation in the presence of solvents with higher acceptor properties

    This research examined public opinion toward genetically modified plants and animals for food, and how trust in organizations and media coverage explained attitudes toward these organisms. Nationally representative samples (N=8821) over 10 years showed Australians were less positive toward genetically modified animals compared to genetically modified plants for food, especially in years where media coverage was high. Structural equation modeling found that positive attitudes toward different genetically modified organisms for food were significantly associated with higher trust in scientists and regulators (e.g. governments), and with lower trust in watchdogs (e.g. environmental movement). Public trust in scientists and watchdogs was a stronger predictor of attitudes toward the use of genetically modified plants for food than animals, but only when media coverage was low. Results are discussed regarding the moral acceptability of genetically modified organisms for food, the media's role in shaping public opinion, and the role public trust in organizations has on attitudes toward genetically modified organisms. © The Author(s) 2014.

    The pharmaco-kinetics of angiographic contrast media in the extra-vascular space, which are largely unknown, were investigated experimentally in dogs. As part of a basic study, using radio-active contrast media, it was possible to determine the concentration and rate of elimination in practically all organs and tissues. Measurements were carried out first after prolonged infusion of contrast under conditions of balanced flow, and secondly six hours after the end of the infusion. It was therefore possible to determine the inflow and loss of contrast medium in various organs, or organs systems. The most commonly used angiographic contrast media in Germany were investigated. Their kinetic behaviour is largely identical, their pattern of distribution and elimination depended principally on the organ or tissue. (orig.) [de

    In today's high technological world, scientific discoveries contribute remarkable development to human life, but it could also have an adverse impact on mankind. Among all these advancements, media is one of the inventions which aims at capturing a countless group of viewers and transmit information via various mediums. Media violence is considered one of the hampering determinants which harms an individual psychologically. The primary goal of a health professional is to work for the maintenance of mental health. Therefore, it is imperative to create an understanding about the impact of media violence on mental health, particularly in the Pakistani context. Violence has become a major public health problem in Pakistan. The main cause of violence seems to be anger and frustration due to poverty, political conflicts, lack of education, and the overall governance approach in the country. Therefore, there is a prime need to think and work on this neglected area like conducting research and increasing public awareness, and to curb media violence.

    The object of this study is to show that the application of radioactivation analysis to the determination of iodine in biological media makes it possible to measure iodine concentrations of the order of 0.0001 μg. After a review of the chemical methods with a mention of the difficulties they present, the optimum conditions for the determination of iodine in biological liquids are given. Three methods are described: - the first consists of a chemical treatment which liberates the protein bound iodine in an inorganic form. After distillation this iodine is irradiated in a flux of thermal neutrons. The induced radioactivity is compared to that of a standard sample irradiated in the same conditions by γ spectrometry. - the second method which is of more general application consists in irradiating the sample and then extracting the iodine; its induced radio-activity is then measured by β-counting. - the third method measures the iodine directly in the thyroid tissue by anti-compton spectrometry. The sensitivity, the reproducibility and the accuracy are discussed. Some applications are described: determination of iodine in its various organic forms in serum, determination of iodine in urines, in food-stuffs, etc., in the thyroid tissue, etc. (author) [fr

    To identify genetic and environmental risk factors for otitis media in an indigenous Filipino population. Cross-sectional study. Indigenous Filipino community. Clinical history and information on breastfeeding, tobacco smoke exposure, and swimming were obtained from community members. Heads of households were interviewed for family history and personal beliefs on ear health. Height and weight were measured. Otoscopic findings were described for the presence and character of perforation or discharge. An A2ML1 duplication variant that confers otitis media susceptibility was Sanger sequenced in all DNA samples. Co-occurrence of middle ear bacteria detected by 16S rRNA gene sequencing was determined according to A2ML1 genotype and social cluster. The indigenous Filipino population has a ~50% prevalence of otitis media. Young age was associated with otitis media (4 age strata; P = .004); however, age was nonsignificant as a bistratal or continuous variable. There was no association between otitis media and sex, body mass index, breastfeeding, tobacco exposure, or deep swimming. In multivariate analyses, A2ML1 genotype is the strongest predictor of otitis media, with an odds ratio of 3.7 (95% confidence interval: 1.3-10.8; P = .005). When otitis media diagnoses were plotted across ages, otitis media was observed within the first year of life, and chronic otitis media persisted up to adulthood, particularly in A2ML1-variant carriers. Among indigenous Filipinos, A2ML1 genotype is the primary risk factor for otitis media and main determinant of disease progression, although age, the middle ear microbiome, and social clusters might modulate the effect of the A2ML1 genotype. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    The media affects individuals' behaviors, especially by means of news and advertisements. In this study, we evaluated health content of organ donation and transplantation news in the printed media and on television programs for a 1-year period in Turkey. We examined 2449 news items in 230 newspapers and magazines; 1179 news programs on 45 television channels, all concerning organ donation and transplantation. The news obtained from the Media Pursuit Center were transferred to an electronic file to evaluate the format and content of the news. Nine variables were examined about the scope and the formal characteristics of the news: the publication name, its type, the province, the date, the headline, the title length, the presence of a photograph, or its kind, the news size, and the page number. In the content analysis of the news, we also examined 9 variables: the topic, the message of the headline, the property of the words in the title, the identification of photographs in the news, the age, gender of actors in the news, as well as donor or recipient. In a summary, print media and television channels, failed to show sufficient information about organ donation and transplantation. The percentage of news about organ donation and transplantation was small and mostly negative items in the media. On television channels, sufficient place was not given to organ donation and transplantation. The news in printed media and on television channels was not about motivated or altruistic behavior. The pattern of organ donation and transplantation news is important in terms of perception and comment by the public. Furthermore it directly affects the perception of the news by the reader.

    Highlights: Black-Right-Pointing-Pointer Applicability of surfactants in constant-current coulometry is shown for the first time. Black-Right-Pointing-Pointer Reactions of antioxidants with electrogenerated titrants in surfactant media are investigated. Black-Right-Pointing-Pointer Water insoluble antioxidants can be determined in water media with addition of surfactants. Black-Right-Pointing-Pointer Coulometric determination of antioxidants in pharmaceutical dosage forms using surfactants media is developed. - Abstract: Effect of surfactant presence on electrochemical generation of titrants has been evaluated and discussed for the first time. Cationic (1-dodecylpyridinium and cetylpyridinium bromide), anionic (sodium dodecyl sulfate) and nonionic (Triton X100 and Brij{sup Registered-Sign} 35) surfactants as well as nonionic high molecular weight polymer (PEG 4000) do not react with the electrogenerated bromine, iodine and hexacyanoferrate(III) ions. The electrogenerated chlorine chemically interact with Triton X100 and Brij{sup Registered-Sign} 35. The allowable range of surfactants concentrations providing 100% current yield has been found. Chain-breaking low molecular weight antioxidants (ascorbic acid, rutin, {alpha}-tocopherol and retinol) were determined by reaction with the electrogenerated titrants in surfactant media. Nonionic and cationic surfactants can be used for the determination of antioxidants by reaction with the electrogenerated halogens. On contrary, cationic surfactants gives significantly overstated results of antioxidants determination with electrogenerated hexacyanoferrate(III) ions. The use of surfactants in coulometry of {alpha}-tocopherol and retinol provides their solubilization and allows to perform titration in water media. Simple, express and reliable coulometric approach for determination of {alpha}-tocopherol, rutin and ascorbic acid in pharmaceuticals using surfactant media has been developed.

    1981-01-01

    Various aspects of the synergistic extraction and separation of actinides and lanthanides from mixed aqueous-organic solutions (polar media) have been reviewed. Notable recent developments as well as its current status in solvent extraction systems where the aqueous acidic phase contains an organic solvent which is completely miscible with water, are presented briefly. In general, extraction increases in the presence of an organic component. The less polar the additive, the higher is the tendency to form neutral metal complexes which ultimately brings about an increase in the extraction. In a polar media, synergism has mostly been observed, though antagonism is not uncommon. An attempt has been made to classify the factors that play an important role in polar phase extractions. Also, their influence particularly on the extractability of actinides and lanthanides is discussed. The discussion is limited to the factors affecting the extraction equilibria, effect of dielectric constant of the polar medium, solvation of the extracting agent and to the composition and stability of the metal complex in the organic phase. Hydroxyl (OHsup(-)) bearing organic additives, e.g. alcohols, and solvents not containing the hydroxyl group such as acetone, dimethylsulphoxide, tetrahydrofuran, amides and acetonitrile etc. are the two major classes of organic additives considered in these studies. Generally, synergistic effect in extraction of the ion-association (TBP, TOPO, sulphoxides etc.) or anion exchange (amines etc.) type is relatively more pronounced compared to other extractions. A tabular summary concerning extraction of actinides and lanthanides from polar media is appended for ready reference. (author)

    The behaviour of polycrystalline fluoride membrane electrode (RFME) in aqueous-organic media has been studied when the content of the organic component (methanol, ethanol, acetone, dioxane) has been changed from 20 to 80 mass%. Since LaF 3 is the base of the membrane, its solubility has been studied depending on the organic component content in the solution. It has been established that LaF 3 solubility decreases with increasing content of of the organic component. This explains the effect of the composition of an aqueous-organic solvent on the electrode sensitivity. The electrode sensitivity rises with increasing content of the organic component in an aqueous-organic solvent. A greater decrease of LaF 3 solubility in aqueous-organic solvents as compared with that of LaCl 3 , La(NO 3 ) 3 , and La 2 (SO 4 ) 3 causes a higher selectivity of RFME with respect to the anions under study

    Cagigal, Elena Fernández-Miranda; Sánchez, Abelardo Casares

    2017-09-01

    The genus Paxillus is characterized by the difficulty of species identification, which results in reproducibility problems, as well as the need for large quantities of fungal inoculum. In particular, studies of Paxillus ammoniavirescens have reported divergent results in the in vitro growth while little is known of its capacity to degrade organic matter. For all the above, and assuming that this variability could be due to an inappropriate culture media, the aim of this study was to analyse growth in different culture media (MMN, MS, and 1/2 MS) and in the case of MMN in presence/absence of two types of organic matter (fresh litter and senescence litter) to probe the saprophytic ability of P. ammoniavirescens . We also evaluated the effects of pH changes in the culture media. Growth kinetics was assessed by weekly quantification of the area of growth in solid culture media over 5 wk, calculating the growth curves and inflection points of each culture media. In addition, final biomass after 5 wk in the different culture media was calculated. Results showed that best culture media are MS and 1/2 MS. Moreover, an improvement in growth in culture media containing decomposing fall litter was observed, leading to confirm differences in the culture media of this species with others of the same genus. Further, we established that all growth media suffered a significant acidification after fungal growth.

    To determine compositions of commercial single-step culture media and test with a murine model whether differences in composition are biologically relevant. Experimental laboratory study. University-based laboratory. Inbred female mice were superovulated and mated with outbred male mice. Amino acid, organic acid, and ions content were determined for single-step culture media: CSC, Global, G-TL, and 1-Step. To determine whether differences in composition of these media are biologically relevant, mouse one-cell embryos were cultured for 96 hours in each culture media at 5% and 20% oxygen in a time-lapse incubator. Compositions of four culture media were analyzed for concentrations of 30 amino acids, organic acids, and ions. Blastocysts at 96 hours of culture and cell cycle timings were calculated, and experiments were repeated in triplicate. Of the more than 30 analytes, concentrations of glucose, lactate, pyruvate, amino acids, phosphate, calcium, and magnesium varied in concentrations. Mouse embryos were differentially affected by oxygen in G-TL and 1-Step. Four single-step culture media have compositions that vary notably in pyruvate, lactate, and amino acids. Blastocyst development was affected by culture media and its interaction with oxygen concentration. Copyright © 2017 American Society for Reproductive Medicine. Published by Elsevier Inc.

    Public media reports about suicide are likely to influence the population's suicidal attempts and completed suicides. Irresponsible reports might trigger copycat suicidal behaviors, while responsible reports may help reduce suicide rates. The World Health Organization (WHO) released recommendations to encourage responsible suicide reports in 2008. However, little is known about whether these recommendations are reflected in the suicide news for most countries, including China. In this study, we assessed the responsibility of suicide stories published in the most influential newspaper and Internet media sources in China from 2003 to 2015, using the media reporting recommendations by the World Health Organization (WHO). In total, 3965 and 1836 eligible stories from newspaper and Internet-based media, respectively, were included in the study. Newspapers and Internet-based media performed similarly in applying WHO recommendations to report suicide news. Three recommendations were applied in over 88% of suicide stories. However, four recommendations were seldom applied, including offering information about where to seek help and linking the suicide event to mental disorders. Government and the journalism industry should work together to improve media reporting of news about suicide in China.

    We examine how presentations of organ donation cases in the media may affect people's willingness to sign organ donation commitment cards, donate the organs of a deceased relative, support the transition to an "opt-out" policy, or donate a kidney while alive. We found that providing identifying information about the prospective recipient (whose life was saved by the donation) increased the participants' willingness to commit to organ donation themselves, donate the organs of a deceased relative, or support a transition to an "opt-out" policy. Conversely, identifying the deceased donor tended to induce thoughts of death rather than about saving lives, resulting in fewer participants willing to donate organs or support measures that facilitated organ donation. A study of online news revealed that identification of the donor is significantly more common than identification of the recipient in the coverage of organ donation cases-with possibly adverse effects on the incidence of organ donations.

    Batch and column experiments were conducted with eucalyptus mulch and commercial compost to evaluate suitability of highly organic natural media to support anaerobic decomposition of trichloroethylene (TCE) in groundwater. Experimental data for TCE and its dechlorination byproducts were analyzed with Hydrus-1D model to estimate the partitioning and kinetic parameters for the sequential dechlorination reactions during TCE decomposition. The highly organic natural media allowed development of a bioactive zone capable of decomposing TCE under anaerobic conditions. The first order TCE biodecomposition reaction rates were 0.23 and 1.2d(-1) in eucalyptus mulch and compost media, respectively. The retardation factors in the eucalyptus mulch and compost columns for TCE were 35 and 301, respectively. The results showed that natural organic soil amendments can effectively support the anaerobic bioactive zone for remediation of TCE contaminated groundwater. The natural organic media are effective environmentally sustainable materials for use in permeable reactive barriers. Copyright © 2012 Elsevier Ltd. All rights reserved.

    2015-03-01

    Full Text Available We employ public management relationship theory to examine how nonprofits can effectively engage social media stakeholders in two-way communication. Though many nonprofit organizations have a social media presence, there is variance in how well organizations use social media to engage stakeholders. Simply having a social media presence is not enough to engage stakeholders.  We examine Facebook posts of a stratified random sample of youth development organizations to determine what predicts stakeholder engagement. We find the type of Facebook post is a significant predictor of stakeholder engagement.  Longer posts also significantly predict increased stakeholder engagement.  At the organizational level, having many posts is a significant negative predictor of stakeholder engagement, indicating that users may feel bombarded and are less likely to engage.  Increased organizational spending on advertising as a proportion of total budget is positively associated with stakeholder engagement.

    2018-01-01

    Background In the recent years, social networking sites (SNSs, also called social media) have been adopted in organ donation campaigns, and recruiting opinion leaders for such campaigns has been found effective in promoting behavioral changes. Objective The aim of this paper was to focus on the dissemination of organ donation tweets on Weibo, the Chinese equivalent of Twitter, and to examine the opinion leadership in the retweet network of popular organ donation messages using social network analysis. It also aimed to investigate how personal and social attributes contribute to a user’s opinion leadership on the topic of organ donation. Methods All messages about organ donation posted on Weibo from January 1, 2015 to December 31, 2015 were extracted using Python Web crawler. A retweet network with 505,047 nodes and 545,312 edges of the popular messages (n=206) was constructed and analyzed. The local and global opinion leaderships were measured using network metrics, and the roles of personal attributes, professional knowledge, and social positions in obtaining the opinion leadership were examined using general linear model. Results The findings revealed that personal attributes, professional knowledge, and social positions predicted individual’s local opinion leadership in the retweet network of popular organ donation messages. Alternatively, personal attributes and social positions, but not professional knowledge, were significantly associated with global opinion leadership. Conclusions The findings of this study indicate that health campaign designers may recruit peer leaders in SNS organ donation promotions to facilitate information sharing among the target audience. Users who are unverified, active, well connected, and experienced with information and communications technology (ICT) will accelerate the sharing of organ donation messages in the global environment.

  7. Two media method for linear attenuation coefficient determination of irregular soil samples

    International Nuclear Information System (INIS)

    Vici, Carlos Henrique Georges

    2004-01-01

    In several situations of nuclear applications, the knowledge of gamma-ray linear attenuation coefficient for irregular samples is necessary, such as in soil physics and geology. This work presents the validation of a methodology for the determination of the linear attenuation coefficient (μ) of irregular shape samples, in such a way that it is not necessary to know the thickness of the considered sample. With this methodology irregular soil samples (undeformed field samples) from Londrina region, north of Parana were studied. It was employed the two media method for the μ determination. It consists of the μ determination through the measurement of a gamma-ray beam attenuation by the sample sequentially immersed in two different media, with known and appropriately chosen attenuation coefficients. For comparison, the theoretical value of μ was calculated by the product of the mass attenuation coefficient, obtained by the WinXcom code, and the measured value of the density sample. This software employs the chemical composition of the samples and supplies a table of the mass attenuation coefficients versus the photon energy. To verify the validity of the two media method, compared with the simple gamma ray transmission method, regular pome stone samples were used. With these results for the attenuation coefficients and their respective deviations, it was possible to compare the two methods. In this way we concluded that the two media method is a good tool for the determination of the linear attenuation coefficient of irregular materials, particularly in the study of soils samples.

    Full Text Available Advocacy organizations rely on social media services, such as Facebook and Twitter, to engage their supporters. These services increasingly influence how citizens and advocacy organizations engage politically online through the technical features and policies they choose to implement—a phenomenon that can sometimes disrupt the work of advocates. Interviews with digital strategists at several US advocacy organizations revealed low levels of awareness of this phenomenon, despite its potential impact on their work; substantial dependence on these services for advocacy work; and a shared sense of necessity to embrace these tools, despite their potential downsides. Implications for the scholarship and practice of Internet governance and digitally mediated advocacy are discussed.

    To determine the composition of commercially available culture media and test whether differences in composition are biologically relevant in a murine model. Experimental laboratory study. University-based laboratory. Cryopreserved hybrid mouse one-cell embryos were used in experiments. Amino acid, organic acid, ions, and metal content were determined for two different lots of media from Cook, In Vitro Care, Origio, Sage, Vitrolife, Irvine CSC, and Global. To determine whether differences in the composition of these media are biologically relevant, mouse one-cell embryos were thawed and cultured for 120 hours in each culture media at 5% and 20% oxygen in the presence or absence of protein in an EmbryoScope time-lapse incubator. The compositions of seven culture media were analyzed for concentrations of 39 individual amino acids, organic acids, ions, and elements. Blastocyst rates and cell cycle timings were calculated at 96 hours of culture, and the experiments were repeated in triplicate. Of the 39 analytes, concentrations of glucose, lactate, pyruvate, amino acids, phosphate, calcium, and magnesium were present in variable concentrations, likely reflecting differences in the interpretation of animal studies. Essential trace elements, such as copper and zinc, were not detected. Mouse embryos failed to develop in one culture medium and were differentially affected by oxygen in two other media. Culture media composition varies widely, with differences in pyruvate, lactate, and amino acids especially notable. Blastocyst development was culture media dependent and showed an interaction with oxygen concentration and presence of protein. Copyright © 2014 American Society for Reproductive Medicine.

    In the past decade, social media has become an integral part of our everyday lives, but research on how this tool is used by public health workers and organizations is still developing. Budget cuts and staff reduction in county departments have required employees to take on more responsibilities. These reductions have caused a reduction in the time for training or collaborating with others in the field. To make up for the loss, many employees are seeking collaboration through social media sites but are unable to do so because state departments block these Internet sites. This study sought to highlight the key considerations and decision-making process for a public health organization deciding whether to implement a social media presence for their organization. Using 3 structured interviews, 15 stakeholders were questioned on their personal experience with social media, experience within the context of public health, and their thoughts on implementation for their center. Interviews were coded using constant comparative qualitative methods. The following themes emerged from the interviews: (1) personal experience with technology and social networking sites, (2) use of social networking sites in public health, (3) use of social networking sites in work environments, (4) social networking sites access, (5) ways the Rural South Public Health Training Center could use social networking sites, and (6) perceived outcomes of social networking site usage for the Rural South Public Health Training Center (positive and negative). The collective voice of the center showed a positive perceived perception of social media implementation, with the benefits outweighing the risks. Despite the benefits, there is a cautious skepticism of the importance of social networking site use.

    This article analyzes three crowdfunded media organizations in three different countries—Krautreporter (Germany, Direkt36 (Hungary, and Colta (Russia. Using qualitative, in-depth interviews, it demonstrates that journalism practices in a crowdfunded newsroom are very different from those in other media. The study concludes that direct funding from the audience is a burden in a practical sense: this business model is financially unstable and increases the amount of work that journalists have to do. At the same time, participants claim to be more satisfied with their work now than they ever were before.

    In the recent years, social networking sites (SNSs, also called social media) have been adopted in organ donation campaigns, and recruiting opinion leaders for such campaigns has been found effective in promoting behavioral changes. The aim of this paper was to focus on the dissemination of organ donation tweets on Weibo, the Chinese equivalent of Twitter, and to examine the opinion leadership in the retweet network of popular organ donation messages using social network analysis. It also aimed to investigate how personal and social attributes contribute to a user's opinion leadership on the topic of organ donation. All messages about organ donation posted on Weibo from January 1, 2015 to December 31, 2015 were extracted using Python Web crawler. A retweet network with 505,047 nodes and 545,312 edges of the popular messages (n=206) was constructed and analyzed. The local and global opinion leaderships were measured using network metrics, and the roles of personal attributes, professional knowledge, and social positions in obtaining the opinion leadership were examined using general linear model. The findings revealed that personal attributes, professional knowledge, and social positions predicted individual's local opinion leadership in the retweet network of popular organ donation messages. Alternatively, personal attributes and social positions, but not professional knowledge, were significantly associated with global opinion leadership. The findings of this study indicate that health campaign designers may recruit peer leaders in SNS organ donation promotions to facilitate information sharing among the target audience. Users who are unverified, active, well connected, and experienced with information and communications technology (ICT) will accelerate the sharing of organ donation messages in the global environment. Medical professionals such as organ transplant surgeons who can wield a great amount of influence on their direct connections could also effectively

    The influence of targeted strategies implemented to increase member engagement on a social media page of a professional pharmacy organization was studied. The Ohio Society of Health-System Pharmacists (OSHP) implemented posting strategies to increase member engagement with its social media page in late 2013. Data were collected retrospectively for a nine-month period in 2013 (preimplementation) and a matching nine-month period in 2014 (postimplementation). The primary endpoint was reach (as provided by the social media website). Data regarding reach were reported to OSHP page administrators on a weekly basis. Posts during the study period were characterized by the day of week, time of day, type of post, and corresponding reach. Continuous variables were represented using means and standard deviations or medians and interquartile ranges (IQRs); categorical data were represented by percentages. The total reach of posts during the nine-month study period increased postimplementation, from 10,826 to 32,338. Further, the median reach per post on the OSHP Facebook page was higher postimplementation (214; IQR, 107-380) versus preimplementation (152; IQR, 89-224; p = 0.035). Evening posts had significantly greater reach compared with nonevening posts. The median reach for evening posts was 232 (IQR, 143-378) versus 131 (IQR, 77-200) for nonevening posts (p system pharmacy organization's social media page.

    2015-12-01

    Full Text Available Social networks such as Facebook and Twitter have recently become very popular and turned to be an effective instrument for achieving political goals. However, the social networks’ impact is rather ambivalent: on the one hand, social media form specific political actors and support self-organization and civil movements; on the other hand, social media reinforce destructive and aggressive manifestations with the pronounced criminal purposes, e.g. social media ability to disseminate information among large groups is used to organize mass riots. The article analyzes one of the recent and significant events largely provoked by the social networks - mass riots in the United Kingdom in August 2011 that were originally a reaction to the murder of M. Diggan by a police officer who tried to arrest him as a suspect in drug trafficking and possession of weapons. The way events developed into mass riots was the result of discussions in social media and use of social networks to coordinate joint actions of mass riots participants. The article provides a detailed description of the events and authorities’ actions to overcome the crisis and prevent such riots in the future, thus making some conclusions about the nature of social media impact on the politics.

    2012-01-01

    The purpose of this volume is to shape conceptual tools to understand the impact of new information and communication technologies (ICTs) on the organization of universities. Traditional research-based universities, the most typical representatives of the higher education system, find themselves challenged by the speed and the wide range of technical innovations, but also by a vast array of implicit assumptions and explicit promises associated with the distribution of digital media.  The author observes that as universities increasingly use digital media (computers and the Internet) to accomplish their tasks, a transformation takes place in an evolutionary rather than in a revolutionary way.  Using the University of Klagenfurt as an in-depth case study, he explores such dynamic issues as how digital media affect the practice of research, the preservation and dissemination of knowledge (for example, through publishing and archiving), and delivery of education at universities.  More broadly, he considers iss...

    Full Text Available This paper aims to identify and analyze the extent to which new media have penetrated the Romanian organizations’ internal communication and have influenced the leadership. We intend also to consider how social media becomes a tool for organizational communication and contributes to the creation of a new kind of leadership associated with open communication. We start from the premise that new media and social media can contribute to the leader’s mission to create around him a vision and makes others to share this vision. In terms of open communication, the external image of organization reflects, in part, leadership practices within the organization. It is about the exercise of the shared collective leadership (Don Tapscott, 1996 that should strengthen the organization position.

    Full Text Available One of the features of democratic political systems is the accountability against their own performances. Media, one of the powerful elements of civil society and effectual on public thought, plays an important role in making the government responsive. To achieve this goal, the present study tries to investigate the effect of media on the improvement of the accountability level of the government agencies. The statistical society of this research includes all male students of Azad Ghaemshahr University where 320 students were selected through purposive sampling method based on Kerjesy and Morgan table. Applied research method is used in this survey. A researcher-made questionnaire was used to collect the required data. In order to validate the instrument, appropriate questions related to each variable were extracted from valid sources and finally approved by authorities. In order to calculate the reliability of the questionnaire, Cronbach’s alpha was calculated to be 89. Since the distribution of the data was normal, parametric statistical tests were used to testify the hypotheses. The findings of the study show that the media could be effective in terms of making public organizations responsive, through leading and training the public, unifying demands, and monitoring and broadcasting. However, the findings reveal that if the media were free and independent, they would better perform their responsibilities. Finally, the study at hand concludes that in comparison to other media, television is much more powerful in terms of pushing the public sector to be responsive.

    Present investigation describes the development of a spectrophotometric method for trace level determination of U(VI) encountered during the process of nuclear fuel fabrication and reprocessing industries. A chromogenic reagent, 2-(5-bromo-2-pyridylazo-5-diethylaminophenol) (Br-PADAP) is used to complex with U(VI) under optimized solution conditions. The absorption maxima of the uranyl Br-PADAP complex at 578 nm is computed to be 73540 ± 1438 for U-Br-PADAP solution containing 20% ethanol (in aqueous sample media) and 58216 ± 1208 for U-Br-PADAP solution containing 80% ethanol (for organic sample media). Employing suitable sample treatment methods, the scope of analytical method has been widened to permit accurate determination of U(VI) in the samples with variation in the relative compositions of Th(IV), Pu(IV) and Fe(III). The method is applicable to samples matrices with, acidic, alkaline highly salted media. Effect of commonly associated ionic species on the optical density of U-Br-PADAP is determined. Depending on the extent of the interfering impurities present, the method permits estimation of U(VI) either direct or after its selective extraction into tri-octyl phosphine oxide dissolved in cyclohexane. The method is precise with <5% standard error and can be used for the estimation of uranium in organic as well as in aqueous samples. The method has been validated for quantitative determination of uranium extracted in the organic phase comprising of heavy metal extractants like TBP, HDEHP, PC-88A and Aliquot 336. (author)

  10. Revenue Sources and Social Media Engagement Among Environmentally Focused Nonprofits

    2017-12-01

    Full Text Available This study examines social media efforts among environmentally focused nonprofits. A survey of environmentally focused nonprofits revealed that more than half of these organizations receive government funding. Prior research demonstrates social media is an efficient medium in which to simultaneously communicate with multiple stakeholders. However, stakeholder engagement is likely tied with the need to raise funds. From that basis, we discuss social media use among nonprofits and develop hypotheses about differences in social media use among organizations receiving government funds and those not receiving government funds. Our hypotheses are rooted in resource dependency theory (RDT and dialogic communication theory (DCT. We test our hypotheses on data from environmentally focused nonprofits by comparing the levels of social media engagement with varying levels of their total funding provided by government grants to determine if there is a correlation with the level of public engagement via social media. We find the level of engagement on the social media site Facebook is lower for government-funded environmental nonprofits than privately funded ones. The findings of reduced social media engagement and the dependence upon government funding versus private funding supports the precepts of resource dependency theory.

    2016-09-01

    The ability of Campylobacter to grow aerobically in media supplemented with fumarate-pyruvate or with dairy, meat, or soy extracts or peptones was examined. Optical densities (OD) of Campylobacter cultured in basal media, media supplemented with fumarate-pyruvate or with 1.0, 2.5, 5.0, or 7.5% beef extract was measured. Growth was also compared in media supplemented with other extracts or peptones. Finally, cfu/mL of Campylobacter recovered from basal media or media supplemented with fumarate-pyruvate, casamino acids, beef extract, soytone, or beef extract and soytone was determined. Results indicated that OD of cultures grown in media supplemented with fumarate-pyruvate or with 5.0 or 7.5% beef extract were higher than OD of isolates grown in basal media or media supplemented with lower concentrations of beef extract. Highest OD were produced by isolates grown in media supplemented with beef extract, peptone from meat, polypeptone, proteose peptone, or soytone. Also, more cfu/mL were recovered from media with fumarate-pyruvate, beef extract, soytone, or beef extract-soytone than from basal media or media with casamino acids. Findings indicate that media supplemented with organic acids, vitamins, and minerals and media supplemented with extracts or peptones containing these metabolites can support aerobic growth of Campylobacter.

    2015-01-01

    A recent trend among health care professionals is the use of social media for professional purposes. These rapidly expanding media allow for timely and efficient access to health information, but they also carry the potential for increased liability. There is a paucity of research detailing how health care professionals, specifically pharmacists, use social media. To characterize the use of social media by pharmacists in the Canadian province of Alberta and to identify independent determinants of and perceived barriers to using social media for professional purposes. Data for this mixed-methods study were collected by an online survey in March and April 2014. Alberta pharmacists were invited to participate via e-mail distributed by 2 professional organizations. The survey had 273 respondents. Of these, 226 (82.8%) stated that they had a social media account for either personal or professional purposes, and 138 (61.1%) of these reported using social media for professional purposes, although most respondents used social media predominantly for personal reasons. The most commonly reported social media applications were Facebook and Twitter, accessed primarily via smartphones. Of the 273 respondents, 206 (75.5%) had a Facebook account, and 101 (49.0%) of these used Facebook to some extent for professional purposes. Twitter users (104 [38.1%] of respondents) had a higher rate of professional utilization (57/104 [54.8%]). The most commonly identified barrier to using social media for professional purposes was concern over liability. Positive predictors of use of social media for professional purposes included younger age and fewer years of professional experience. Participants perceived the most beneficial aspect of social media (in professional terms) as connecting with pharmacist colleagues. More than 80% of pharmacists in Alberta reported that they had a social media account, and over half of them reported using their accounts for professional purposes. Although

    The choice of soilless growing medium for plant nutrition, growth and support is crucial for improving the eco-sustainability of the production in horticultural systems. As our current understanding of the functional microbial communities inhabiting this ecosystem is still limited, we examined the microbial community development of the two most important growing media (organic and mineral) used in open soilless horticultural systems. We aimed to identify factors that influence community composition over time, and to compare the distribution of individual taxa across growing media, and their potential functionality. High throughput sequencing analysis revealed a distinctive and stable microbial community in the organic growing medium. Humidity, pH, nitrate-N, ammonium-N and conductivity were uncovered as the main factors associated with the resident bacterial communities. Ammonium-N was correlated with Rhizobiaceae abundance, while potential competitive interactions among both Methylophilaceae and Actinobacteridae with Rhizobiaceae were suggested. Our results revealed that soilless growing media are unique niches for diverse bacterial communities with temporal functional stability, which may possibly impact the resistance to external forces. These differences in communities can be used to develop strategies to move towards a sustainable horticulture with increased productivity and quality.

    Full Text Available The widespread adoption of social media by users and organizations has generated an exponential increase in data and content that offer opportunities to be processed into information and knowledge. However, dealing with such data is considered a challenge and requires the use of adequate resources. Considering this scenario, the aim of this study was to present a social media monitoring model to support decision making by DMOs. The model proposed has been tested before and during the 2014 FIFA World Cup, using Curitiba and Foz do Iguaçu (Paraná State as destinations, having a structured of seven stages. The results of the period were composed of about 50,000 messages, tours and associated ontology application. A large part of the frequency relations, between attractions or between host cities, have been com-patible with their reality in the tourist trade.

    The particle size and heaped methods of exhalation media have important effects on physical parameters, such as the free radon production rate, porosity, permeability, and radon diffusion coefficient. However, existing methods for determining those parameters are too complex, and time-consuming. In this study, a novel, systematic determining method was proposed based on nuclide decay, radon diffusion migration theory, and the mass conservation law, and an associated experimental device was designed and manufactured. The parameters of uranium ore heap and sandy soil of radon diffusion coefficient (D), free radon production rate (α), media permeability (k), and porosity (ε) were obtained. At the same time, the practicality of the novel determining method was improved over other methods, with the results showing that accuracy was within the acceptable range of experimental error. This novel method will be of significance for the study of radon migration and exhalation in granulated porous media. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Not only is locative media one of the fastest growing areas in digital technology, but questions of location and location-awareness are increasingly central to our contemporary engagements with online and mobile media, and indeed media and culture generally. This volume is a comprehensive account of the various location-based technologies, services, applications, and cultures, as media, with an aim to identify, inventory, explore, and critique their cultural, economic, political, social, and policy dimensions internationally. In particular, the collection is organized around the perception that the growth of locative media gives rise to a number of crucial questions concerning the areas of culture, economy, and policy.

  6. Kinetics of acyl transfer reactions in organic media catalysed by Candida antarctica lipase B.

    Martinelle, M; Hult, K

    1995-09-06

    The acyl transfer reactions catalysed by Candida antartica lipase B in organic media followed a bi-bi ping-pong mechanism, with competitive substrate inhibition by the alcohols used as acyl acceptors. The effect of organic solvents on Vm and Km was investigated. The Vm values in acetonitrile was 40-50% of those in heptane. High Km values in acetonitrile compared to those in heptane could partly be explained by an increased solvation of the substrates in acetonitrile. Substrate solvation caused a 10-fold change in substrate specificity, defined as (Vm/Km)ethyl octanoate/(Vm/Km)octanoic acid, going from heptane to acetonitrile. Deacylation was the rate determining step for the acyl transfer in heptane with vinyl- and ethyl octanoate as acyl donors and (R)-2-octanol as acyl acceptor. With 1-octanol, a rate determining deacylation step in heptane was indicated using the same acyl donors. Using 1-octanol as acceptor in heptane, S-ethyl thiooctanoate had a 25- to 30-fold lower Vm/Km value and vinyl octanoate a 4-fold higher Vm/Km value than that for ethyl octanoate. The difference showed to be a Km effect for vinyl octanoate and mainly a Km effect for S-ethyl thiooctanoate. The Vm values of the esterification of octanoic acid with different alcohols was 10-30-times lower than those for the corresponding transesterification of ethyl octanoate. The low activity could be explained by a low pH around the enzyme caused by the acid or a withdrawing of active enzyme by nonproductive binding by the acid.

    Raphael, Dennis

    2011-06-01

    This article explores the dearth of coverage of the social determinants of health by the Canadian mainstream media. It is argued that this neglect is primarily a reflection of political and economic societal structures that has been associated with increasing corporate control of the mainstream media. Applying a critical political economy lens, it is argued that the barriers to having the Canadian mainstream media report on the social determinants of health are so numerous that it may indeed be 'time to call it a day' in regard to having them assist in the dissemination of social determinants of health findings. Recognizing this reality should spur the development of alternative means of communicating with the public in order to develop a citizens' movement to create health-promoting public policy. Recent dissemination efforts related to the Social Determinants of Health: The Canadian Facts provide an example of how this might be accomplished.

    Full Text Available The development of the internet and the expansion of digitalization changed the way society works, especially mass-media. The question is if the internet was an advantage or a disadvantage for mass-media? Apparently, on one hand digitalization determined the reduction of production and distribution costs but also content diversification. At the same time, social media and rapid documentation brought an accession in the quality of journalistic product as well as the entering on the market of multiple actors, in consequence, more ideas more carefully selected. On the other hand, it is possible that the internet may have increased the volume of information, detrimental to its credibility. In other words, the quality of the journalistic act and its results have been altered or at least crippled. Methodologically, starting from the observation of the actual situation in mass-media industry and economy, we propose to make a content analysis. We will talk about aspects concerning the challenges and the opportunities from media industry in the digital context, analyzing the opinions of other researchers about the topic. We are trying to present the concepts that we sustain in the light of some reference works and to give examples from the reality of Romanian and international mass-media economy. The mass-media sector in the digital world is confronting with opportunities and challenges. The change isn’t simple and without risks but is expensive and may be the only way of survival for each of the societies in this sector. In order to build successful businesses in media industry just like in any other sectors, sustainable growth has to be the main characteristic. Sustainable development, predictability and upward economic growth are possible only taking into account the context in which the organization operates.

    Although it has been widely demonstrated that surfactants can efficiently control the size, shape and surface properties of micro/nanocrystals of metal–organic frameworks (MOFs) due to the strong interactions between surfactants and crystal facets of MOFs, the use of surfactants as reaction media to grow MOF single crystals is unprecedented. In addition, compared with ionic liquids, surfactants are much cheaper and can have multifunctional properties such as acidic, basic, neutral, cationic, anionic, or even block. These factors strongly motivate us to develop a new synthetic strategy: growing crystalline MOFs in surfactants. In this report, eight new two-dimensional (2D) or three-dimensional (3D) MOFs have been successfully synthesized in an industrially-abundant and environmentally-friendly surfactant: polyethylene glycol-200 (PEG-200). Eight different coordination modes of carboxylates, ranging from monodentate η{sup 1} mode to tetra-donor coordination µ{sub 3}-η{sup 1}:η{sup 2}:η{sup 1} mode, have been founded in our research. The magnetic properties of Co-based MOFs were investigated and MOF NTU-Z6b showed a phase transition with a Curie temperature (T{sub c}) at 5 K. Our strategy of growing crystalline MOFs in surfactant could offer exciting opportunities for preparing novel MOFs with diverse structures and interesting properties. - Graphical abstract: Surfactants have been used as reaction media to grow MOF single crystals for the first time.

    2014-04-01

    Debates and controversies have shaped the understanding and the practices related to death determined by neurological criterion (DNC). Confusion about DNC in the public domain could undermine this notion. This confusion could further jeopardise confidence in rigorous death determination procedures, and raise questions about the integrity, sustainability, and legitimacy of modern organ donation practices. We examined the depictions of 'brain death' in major American and Canadian print media to gain insights into possible common sources of confusion about DNC and the relationship between expert and lay views on this crucial concept. We gathered 940 articles, available in electronic databases, published between 2005 and 2009 from high-circulation Canadian and American newspapers containing keywords 'brain dead' or 'brain death'. Articles were systematically examined for content (eg, definitions of brain death and criteria for determination of death) using the NVivo 8 software. Our results showed problematic aspects in American and Canadian media, with some salient differences. DNC was used colloquially in 39% (N=366) of the articles and its medical meaning infrequently defined (2.7%; N=14 in the USA and 3.6%; N=15 in Canada). The neurological criterion for determination of death was mentioned in less than 10% of the articles, and life support in about 20% of the articles. Organ donation issues related to DNC were raised more often in Canadian articles than in American articles (33.5% vs 21.2%; p<0.0001). Further discussion is needed to develop innovative strategies to bridge media representations of DNC with experts' views in connection with organ donation practices.

    Research suggests that the representation of scientific and medical issues in the traditional media such as newspapers, TV and radio is an important determinant of public opinion and related public policy outcomes, particularly with regard to attitudes toward stem cell research. With the emergence of social media, the discursive space around public policy issues has expanded to include a new demographic of media consumer who is directly involved in political action. However, little is known about the influence of social media on scientific public policy conversations. We analyzed Twitter posts on two topics relating to stem cell science and policy according to the originator and tone of the tweet, and whether the tweet was intended to be neutral or to further a stated policy position. This analysis provides a means for clarifying the role of social media in influencing public opinion of policy issues such as stem cell research and offers organizations a better understanding of how to more effectively apply social media to advancing their stem cell policy positions.

    2016-11-01

    The growth of social media presents opportunities for public health to increase its influence and impact on the social determinants of health and health equity. The National Collaborating Centre for Determinants of Health at St. Francis Xavier University conducted a survey during the first half of 2016 to assess how public health used social media for knowledge translation, relationship building, and specific public health roles to advance health equity. Respondents reported that social media had an important role in public health. Uptake of social media, while relatively high for personal use, was less present in professional settings and varied for different platforms. Over 20 per cent of those surveyed used Twitter or Facebook at least weekly for knowledge exchange. A lesser number used social media for specific health equity action. Opportunities to enhance the use of social media in public health persist. Capacity building and organizational policies that support social media use may help achieve this.

    2015-09-01

    Full Text Available Through an analysis of European newspapers, human rights organization reportage, and United Nations documents and websites, this article examines how public discourse regarding education, human rights, poverty, child rearing, and child labour manufactures a dangerous, implausible childhood for Romani children. These discourses, perpetrated by human rights organizations and news media, leverage the languages of intervention, cultural difference, nationalism, and social justice to simultaneously victimize and vilify Romani children, rendering them incapable of experiencing humane childhoods. Employing critical discourse analysis and systemic functional grammar analysis, the proposed article seeks to disentangle the discourses of human rights for Roman children from the assimilationist arguments aimed at compulsory schooling and Eurocentric family and labour practices rooted in access to middle class dominant labor markets.

  9. The effect of organic contaminants on the spectral induced polarization response of porous media - mechanistic approach

    Science.gov (United States)

    Schwartz, N.; Huisman, J. A.; Furman, A.

    2012-12-01

    In recent years, there is a growing interest in using geophysical methods in general and spectral induced polarization (SIP) in particular as a tool to detect and monitor organic contaminants within the subsurface. The general idea of the SIP method is to inject alternating current through a soil volume and to measure the resultant potential in order to obtain the relevant soil electrical properties (e.g. complex impedance, complex conductivity/resistivity). Currently, a complete mechanistic understanding of the effect of organic contaminants on the SIP response of soil is still absent. In this work, we combine laboratory experiments with modeling to reveal the main processes affecting the SIP signature of soil contaminated with organic pollutant. In a first set of experiments, we investigate the effect of non-aqueous phase liquids (NAPL) on the complex conductivity of unsaturated porous media. Our results show that addition of NAPL to the porous media increases the real component of the soil electrical conductivity and decreases the polarization of the soil (imaginary component of the complex conductivity). Furthermore, addition of NAPL to the soil resulted in an increase of the electrical conductivity of the soil solution. Based on these results, we suggest that adsorption of NAPL to the soil surface, and exchange process between polar organic compounds in the NAPL and inorganic ions in the soil are the main processes affecting the SIP signature of the contaminated soil. To further support our hypothesis, the temporal change of the SIP signature of a soil as function of a single organic cation concentration was measured. In addition to the measurements of the soil electrical properties, we also measured the effect of the organic cation on the chemical composition of both the bulk and the surface of the soil. The results of those experiments again showed that the electrical conductivity of the soil increased with increasing contaminant concentration. In addition

    The authors discuss a new unsteady-state method proposed for determining the moisture transport properties in wet porous media. It is based on measurement of the change in moment of gravity caused by the moisture migration. In addition to its high-speed performance, this method may get rid of the difficulty in determination of a changing moisture content or moisture distribution. On this basis, two particular procedures are contrived: a constant heat source method for determining the thermal mass diffusivity and an instantaneous moisture source method for determining the moisture diffusivity

    Spiro, Emma S; Monroy-Hernández, Andrés

    2016-01-01

    In this paper we examine two protests characterized by substantial social media presence and distributed participation frameworks via two core questions: what roles did organizations and individuals play, and how did participants' social interactions change over the course of the protests? To answer these questions, we analyzed a large Twitter activity dataset for the #YoSoy132 student uprising in Mexico and Brazil's "bus rebellion." Results indicate that individuals initially took prominence at the protests but faded in importance as the movements dwindled and organizations took over. Regarding the dynamics and structure of the interactions, we found that key time points with unique social structures often map to exogenous events such as coordinated protests in physical locations. Our results have important consequences for the visibility of such social movements and their ability to attract continued participation by individuals and organizations.

    2011-02-01

    Full Text Available The article examines different methods for determining organic matter and colour in water. Most of organic compounds in water have a humic substance. These substances frequently form complexes with iron. Humic matter gives water a yellow-brownish colour. Water filtration through conventional sand filters does not remove colour and organic compounds, and therefore complicated water treatment methods shall be applied. The methods utilized for organic matter determination in water included research on total organic carbon, permanganate index and the bichromate number of UV absorption of 254 nm wave length. The obtained results showed the greatest dependence between water colour and permanganate index. However, UV adsorption could be used for organic matter determination during the operation of a water treatment plant and the start-up of plants as easy and fast methods.Article in Lithuanian

    2009-11-01

    Folic acid, hypoxanthine, mycophenolic acid, nicotinic acid, riboflavin, and xanthine are widely used as cell culture media components in monoclonal antibody manufacturing. These components are subsequently removed during the downstream purification processes. This article describes a single MEKC method that can simultaneously determine all the listed compounds with acceptable LOD and LOQ. All the analytes were successfully separated by MEKC using running buffer containing 40 mM SDS, 20 mM sodium phosphate, and 20 mM sodium borate at pH 9.0. The MEKC method was compared to the corresponding CZE method using the same running buffer containing no SDS. The effect of SDS concentration on separation, the pH of the running buffer, and the detection wavelength were studied and optimal MEKC conditions were established. Good linearity was obtained with correlation coefficients of more than 0.99 for all analytes. Specificity, accuracy, and precision were also evaluated. The recovery was in the range of 89-112%. The precision results were in the range of 1.7-4.8%. The experimentally determined data demonstrated that the MEKC method is applicable to the determination of the six analytes in in-process samples from monoclonal antibody manufacturing processes.

  16. METHODS FOR THE DETERMINATION OF TOTAL ORGANIC ...

    Science.gov (United States)

    Organic matter in soils and sediments is widely distributed over the earth's surface occurring in almost all terrestrial and aquatic environments (Schnitzer, 1978). Soils and sediments contain a large variety of organic materials ranging from simple sugars and carbohydrates to the more complex proteins, fats, waxes, and organic acids. Important characteristics of the organic matter include their ability to: form water-soluble and water- insoluble complexes with metal ions and hydrous oxides; interact with clay minerals and bind particles together; sorb and desorb both naturally-occurring and anthropogenically-introduced organic compounds; absorb and release plant nutrients; and hold water in the soil environment. As a result of these characteristics, the determination of total organic carbon (a measure of one of the chemical components of organic matter that is often used as an indicator of its presence in a soil or sediment) is an essential part of any site characterization since its presence or absence can markedly influence how chemicals will react in the soil or sediment. Soil and sediment total organic carbon (TOC) determinations are typically requested with contaminant analyses as part of an ecological risk assessment data package. TOC contents may be used qualitatively to assess the nature of the sampling location (e.g., was it a depositional area) or may be used to normalize portions of the analytical chemistry data set (e.g., equilibrium partitioning).

    Highly sensitive and interference-free sensitized spectrophotometric method for the determination of Ni(II) ions is described. The method is based on the reaction between Ni(II) ion and benzyl dioxime in micellar media in the presence of sodium dodecyl sulfate (SDS). The absorbance is linear from 0.1 up to 25.0 μg mL -1 in aqueous solution with repeatability (RSD) of 1.0% at a concentration of 1 μg mL -1 and a detection limit of 0.12 ng mL -1 and molar absorption coefficient of 68,600 L mol -1 cm -1. The influence of reaction variables including type and amount of surfactant, pH, and amount of ligand and complexation time and the effect of interfering ions are investigated. The proposed procedure was applied to the determination of trace amounts of Ni(II) ion in tap water, river water, chocolate and vegetable without separation or organic solvent extraction.

    Screen media usage, sleep time and socio-demographic features are related to adolescents' academic performance, but interrelations are little explored. This paper describes these interrelations and behavioral profiles clustered in low and high academic performance. A nationally representative sample of 3,095 Spanish adolescents, aged 12 to 18, was surveyed on 15 variables linked to the purpose of the study. A Self-Organizing Maps analysis established non-linear interrelationships among these variables and identified behavior patterns in subsequent cluster analyses. Topological interrelationships established from the 15 emerging maps indicated that boys used more passive videogames and computers for playing than girls, who tended to use mobile phones to communicate with others. Adolescents with the highest academic performance were the youngest. They slept more and spent less time using sedentary screen media when compared to those with the lowest performance, and they also showed topological relationships with higher socioeconomic status adolescents. Cluster 1 grouped boys who spent more than 5.5 hours daily using sedentary screen media. Their academic performance was low and they slept an average of 8 hours daily. Cluster 2 gathered girls with an excellent academic performance, who slept nearly 9 hours per day, and devoted less time daily to sedentary screen media. Academic performance was directly related to sleep time and socioeconomic status, but inversely related to overall sedentary screen media usage. Profiles from the two clusters were strongly differentiated by gender, age, sedentary screen media usage, sleep time and academic achievement. Girls with the highest academic results had a medium socioeconomic status in Cluster 2. Findings may contribute to establishing recommendations about the timing and duration of screen media usage in adolescents and appropriate sleep time needed to successfully meet the demands of school academics and to improve

    Full Text Available Implementing social media in the workplace may make it easier for employees to participate in knowledge sharing activities such as Q&A and ideation. However, vetting the quality of answers and ideas becomes more complex when anyone in the company can contribute. Research on the use of social media for Q&A has shown that certain characteristics and reputation algorithms can help determine the best answers. Less is known about the ideation process and the way it plays out in social media. This paper explores the use of enterprise social media (ESM for ideation by employees in a large Russian organization distributed across nine time zones. In particular, we explore which characteristics of both ideas and their contributors predict whether ideas get accepted or rejected. Our analysis is based on logistic regression analysis of a sample of 488 ideas contributed in an ESM tool used in the organization as well as a content analysis of the types of ideas generated. Our results suggest that rather than being truly democratic and decentralized, ideation in ESM is driven by those in (or proximate to positions of organizational power.

    1999-01-01

    Amines with long hydro carbonic strength and principally Trioclkylamines, are characterised by an important complexation mechanism for certain metals. This is the case for trioctylamine (TOA) which is very used in purification and uranium recovery from certain ores (1,2). This substance is generally found mixed with mono and di-octyl amines in commercial products and in synthesis mixtures. The purpose of this work is to develop a pH titration method in an organic media for a mixture consisted of mono, di and tri octyl amines (MOA, DOA et TOA). Adequate operating analysis condition have been proposed, based on intrinsic chemical properties for each precipitated substances (3,4). The obtained results show that this technique is recommended for qualitative and quantitative analysis of precipitated amines mixtures. The method is reproducible and the detection limit can reach 0,0001 molar

    Media advocacy is the strategic use of mass media and community organizing as a resource for advancing a social or public policy initiative. Across the United States, communities are using media advocacy to promote healthier public policies and environments. The U.S. Center for Substance Abuse Prevention commissioned numerous case studies of media advocacy on alcohol and tobacco issues in a diverse array of communities, including efforts in African-American and Latino communities or using computer-based electronic communication systems. The paper describes these efforts briefly, and summarizes lessons learned, including: media advocacy can lead to larger victories when used as a complement to community organizing in the context of a larger strategic vision for policy change; like policy advocacy, media advocacy is best done in the context of clear long-term goals; conscious framing, guiding the choice of spokespeople, visuals, and messages, can alter media coverage and public debate of health policies; advocates need to respect the media but also remember that they have power in relation to the media; and media advocacy is often controversial and not suited to every situation. The case studies show that media advocacy is a potent tool for public health workers, making an important contribution to campaigns to promote healthier public policies.

    Traditional measures of the impact of published research, such as citation counts, are limited to measuring academic impact. The use of social media and other online tools as alternative measures of research impact is gaining popularity and used by leading medical journals. MEDLINE was searched for articles published with subject headings relating to solid organ transplantation between August 1, 2011, and July 31, 2012. Citation data were retrieved from SCOPUS, and statistics regarding mentions in social media, social bookmarking sites, news outlets, and expert recommendation sites were retrieved from the data at www.altmetric.com. Data were analyzed for associations between alternative metric data and citation rates. The search retrieved 6,981 publications. Sixty-six percent of the articles had at least one citation. Mentions in social media were 19.3%, 13.1% had social bookmarks, 0.9% had expert recommendations, and online news outlets picked up eight articles. Significantly higher citation rates were associated with mention in social media, expert recommendation, social bookmarking, and for articles identified as meta-analyses, multicenter studies, randomized controlled trials, and reviews (all Psocial media (odds ratio, 2.58; Psocial media are more likely to relate to the more controversial and emotive areas of transplantation. Social media and online attention act as early predictors of the impact of transplant research as measured by later citation rate. Blogging and expert recommendation, in particular, are associated with higher citation rates.

    Agrochemicals such as the insecticide Fipronil that bear fluoro groups are generally fat-soluble and nearly insoluble in water, so that their photodegradation in a heterogeneous aqueous gallium oxide dispersion presents some challenges. This article examined the photodegradation of this insecticide by solubilizing it through the addition of organic solvents (EtOH, MeOH, THF, 1,4-dioxane and ethylene glycol) to an aqueous medium and then subjecting the insecticide to 254 nm UVC radiation under photocatalytically inert (Ga2O3/N2) and air-equilibrated (Ga2O3/O2) conditions, as well as photochemically in the absence of Ga2O3 but also under inert and air-equilibrated conditions. Defluorination, dechlorination, desulfonation and denitridation of Fipronil were examined in mixed aqueous/organic media (10, 25 and 50 vol% in organic solvent). After 3 h of UVC irradiation (50 vol% mixed media) defluorination with Ga2O3/N2 was ∼65% greater than in aqueous media, and ca. 80% greater than the direct photolysis of Fipronil under inert (N2) conditions; under air-equilibrated conditions both Ga2O3-photocatalyzed and photochemical defluorination were significantly lower than in aqueous media. Dechlorination of Fipronil was ∼160% (Ga2O3/N2) and 140% (photochemically, N2) greater than in aqueous media; under air-equilibrated conditions, both photocatalyzed and photochemical formation of Cl(-) ions in mixed media fell rather short relative to aqueous media. The photocatalyzed (Ga2O3/N2) and photochemical (N2) conversion of the sulfur group in Fipronil to SO4(2(-)) ions was ca. 20% and 30% greater, respectively, in mixed media, while under air-equilibrated conditions photocatalyzed desulfonation was nearly twofold less than in the aqueous phase; direct photolysis showed little variations in mixed media. Denitridation of the nitrogens in Fipronil occurred mostly through the formation of ammonia (as NH4(+)) under all conditions with negligible quantities of NO3(-); again mixed media

    To accomplish the aims of public health practice and policy today, new forms of communication and education are being applied. Social media are increasingly relevant for public health and used by various actors. Apart from benefits, there can also be risks in using social media, but policies regulating engagement in social media is not well researched. This study examined European public health-related organizations' social media policies and describes the main components of existing policies. This research used a mixed methods approach. A content analysis of social media policies from European institutions, non-government organizations (NGOs) and social media platforms was conducted. Next, individuals responsible for social media in their organization or projects completed a survey about their social media policy. Seventy-five per cent of institutions, NGOs and platforms had a social media policy available. The primary aspects covered within existing policies included data and privacy protection, intellectual property and copyright protection and regulations for the engagement in social media. Policies were intended to regulate staff use, to secure the liability of the institution and social responsibility. Respondents also stressed the importance of self-responsibility when using social media. This study of social media policies for public health in Europe provides a first snapshot of the existence and characteristics of social media policies among European health organizations. Policies tended to focus on legal aspects, rather than the health of the social media user. The effect of such policies on social media adoption and usage behaviour remains to be examined. © The Author 2014.

    Culturing microorganisms is a critical step in understanding and utilizing microbial life. Here we map the landscape of existing culture media by extracting natural-language media recipes into a Known Media Database (KOMODO), which includes >18,000 strain–media combinations, >3300 media variants and compound concentrations (the entire collection of the Leibniz Institute DSMZ repository). Using KOMODO, we show that although media are usually tuned for individual strains using biologically common salts, trace metals and vitamins/cofactors are the most differentiating components between defined media of strains within a genus. We leverage KOMODO to predict new organism–media pairings using a transitivity property (74% growth in new in vitro experiments) and a phylogeny-based collaborative filtering tool (83% growth in new in vitro experiments and stronger growth on predicted well-scored versus poorly scored media). These resources are integrated into a web-based platform that predicts media given an organism's 16S rDNA sequence, facilitating future cultivation efforts. PMID:26460590

    Full Text Available Computerization, digitalization and datafication are by far no neutral or self-dependent occurrences. They are, to a large degree, co-determined by heterogeneous actors who reflect about, construct, configure, manipulate or even control media. The contributors to this issue put the spotlight on these actors and investigate how they influence, shape and (reconfigure broader social constellations. Instead of exploring what people do with media, the articles focus on the many ways individuals, civil society initiatives, corporations and social movements act on media. The notion of acting on media denotes the efforts of a wide range of actors to take an active part in the molding of media organizations, infrastructures and technologies that are part of the fabric of everyday life. Therefore, by conceptualizing acting on media as a form of political action, the issue aims to contribute to ongoing discussions on the media practice paradigm.

    Highlights: • New soil remediation process using phase transition of partially miscible solvents. • Design and synthesis of new bio-degradable, organic soluble chelating agents. • Feasibility tests of the process on authentically polluted sediments and sludge. • Simultaneous removal of toxic metals and organic pollutants was demonstrated. -- Abstract: Advanced biodegradable and non-toxic organic chelators, which are soluble in organic media, were synthesized on the basis of the S,S-ethylenediamine-disuccinate (S,S-EDDS) ligand. The modifications suggested in this work include attachment of a lipophilic hydrocarbon chain (“tail”) to one or both nitrogen atoms of the S,S-EDDS. The new ligands were designed and evaluated for application in the Sediments Remediation Phase Transition Extraction (SR-PTE) process. This novel process is being developed for the simultaneous removal of both heavy metals and organic pollutants from contaminated soils, sediments or sludge. The new chelators were designed to bind various target metal ions, to promote extraction of these ions into organic solvents. Several variations of attached tails were synthesized and tested. The results for one of them, N,N′-bis-dodecyl-S,S-EDDS (C24-EDDS), showed that the metal-ligand complexes are concentrated in the organic-rich phase in the Phase Transition Extraction process (more than 80%). Preliminary applications of the SR-PTE process with the C24-EDDS ligand were conducted also on actually contaminated sludge (field samples). The extraction of five toxic metals, namely, Cd, Cu, Ni, Pb and Zn was examined. In general, the extraction performance of the new ligand was not less than that of S,S-EDDS when a sufficient ligand-to-extracted ion ratio (about 4:1 was applied

    Full Text Available What should be the media of a modern education institution? How is the educational organization supposed to be represented in social media? What methods of increasing the level of media literacy of teachers and students should optimally use?As the purpose of this study the authors can see in the development and presentation of an optimal model of media space for modern educational institutions which will take into account not only the changes in the education process, but also the needs of the modern audience – teachers, students, parents, and educational partners. The resources of “Moscow e-school” become part of the educational media sphere of modern educational organizations.Resources and methods: resources of an educational institution, namely, social media, blogs and microblogs, users’ accounts, channels, educational platforms, which present the work of educators. The importance of analyzing media of the modern educational institution is that media-education serves as a pedagogical system, allowing the use of modern techniques and technologies through the development of critical thinking, which occurs under the influence of information flows. In this regard, there is a need for the comprehensive approach to the media organization in the modern school. An integral element of the complex approach is the creation of conditions for the development of media literacy for teachers and learners.The result of this research is the optimal model of media space for the modern school, which includes social networking profiles, microblogging, blogs, users’ accounts, and web resources, each of which has its own purpose and functional features.As a conclusion we can note that one of the core values of the media model is the development of creative and critical thinking, the acquisition of experience and tools of media, independent search, the ability to use information flows for the effective communication, solving educational and cognitive

    Niedz, Randall P

    2016-01-01

    ARS-Media for Excel is an ion solution calculator that uses "Microsoft Excel" to generate recipes of salts for complex ion mixtures specified by the user. Generating salt combinations (recipes) that result in pre-specified target ion values is a linear programming problem. Excel's Solver add-on solves the linear programming equation to generate a recipe. Calculating a mixture of salts to generate exact solutions of complex ionic mixtures is required for at least 2 types of problems- 1) formulating relevant ecological/biological ionic solutions such as those from a specific lake, soil, cell, tissue, or organ and, 2) designing ion confounding-free experiments to determine ion-specific effects where ions are treated as statistical factors. Using ARS-Media for Excel to solve these two problems is illustrated by 1) exactly reconstructing a soil solution representative of a loamy agricultural soil and, 2) constructing an ion-based experiment to determine the effects of substituting Na+ for K+ on the growth of a Valencia sweet orange nonembryogenic cell line.

    ARS-Media for Excel is an ion solution calculator that uses “Microsoft Excel” to generate recipes of salts for complex ion mixtures specified by the user. Generating salt combinations (recipes) that result in pre-specified target ion values is a linear programming problem. Excel’s Solver add-on solves the linear programming equation to generate a recipe. Calculating a mixture of salts to generate exact solutions of complex ionic mixtures is required for at least 2 types of problems– 1) formulating relevant ecological/biological ionic solutions such as those from a specific lake, soil, cell, tissue, or organ and, 2) designing ion confounding-free experiments to determine ion-specific effects where ions are treated as statistical factors. Using ARS-Media for Excel to solve these two problems is illustrated by 1) exactly reconstructing a soil solution representative of a loamy agricultural soil and, 2) constructing an ion-based experiment to determine the effects of substituting Na+ for K+ on the growth of a Valencia sweet orange nonembryogenic cell line.

    2014-01-01

    Given the high rate of social media use by the public, organizations are compelled to engage with key audiences through these outlets. Social media engagement requires organizations to actively participate with public groups, and this highly-interactive exchange raises a new set of ethical concerns for communicators. In this rapidly changing communications environment, the long-term implications of social media are uncertain, and this book provides the much needed research to understand its impact on audiences and organizations.Through an examination of a broad range of ethics concepts includi

    To use ecological momentary assessment techniques to measure the association of major depressive disorder (MDD) with media use. Data were collected using an ecological momentary assessment protocol with cellular telephone-based brief interviews. Participants received as many as 60 telephone calls from a trained staff member during 5 extended weekends in an 8-week period. One hundred six adolescent participants who were part of a larger neurobehavioral study of depression in Pittsburgh from January 1, 2003, through December 31, 2008. At each call, participants were asked whether they were using the following 5 types of media: television or movies, music, video games, Internet, and print media, such as magazines, newspapers, and books. We developed multivariable models to determine the independent association of each type of media use with MDD, controlling for sociodemographic variables. Of the 106 participants, 46 were diagnosed as having MDD. In multivariable models controlling for age, sex, and race, each increasing quartile of audio use was associated with an 80% increase in the odds of having MDD (odds ratio, 1.8; 95% confidence interval, 1.1-2.8; P = .01 for trend). Conversely, each increasing quartile of print media use was associated with a 50% decrease in the odds of having MDD (odds ratio, 0.5; 95% confidence interval, 0.3-0.9; P = .009 for trend). Major depressive disorder is positively associated with popular music exposure and negatively associated with reading print media such as books. Further research elucidating the directionality and strength of these relationships may help advance understanding of the relationships between media use and MDD.

    Scholars have expressed concern that the introduction of substantial coverage of "medical genetics" in the mass media during the past 2 decades represents an increase in biological determinism in public discourse. To test this contention, we analyzed the contents of a randomly selected, structured sample of American public newspapers (n=250) and magazines (n=722) published during 1919-95. Three coders, using three measures, all with intercoder reliability >85%, were employed. Results indicate that the introduction of the discourse of medical genetics is correlated with both a statistically significant decrease in the degree to which articles attribute human characteristics to genetic causes (P<.001) and a statistically significant increase in the differentiation of attributions to genetic and other causes among various conditions or outcomes (P<. 016). There has been no statistically significant change in the relative proportions of physical phenomena attributed to genetic causes, but there has been a statistically significant decrease in the number of articles assigning genetic causes to mental (P<.002) and behavioral (P<.000) characteristics. These results suggest that the current discourse of medical genetics is not accurately described as more biologically deterministic than its antecedents. PMID:9529342

    2010-01-01

    As a fundamental research on the optimization of electrolyte composition in practical electrochemical capacitor device, double-layer capacitance at Glassy Carbon (GC) and Boron-doped Diamond (BDD), as typical smooth-surface carbon electrodes, has been studied as a function of the electrolyte composition in organic media. Specific capacitance (differential capacitance: F cm -2 ) determined by an AC impedance method, in which no contribution of mass-transport effects is included, corresponded well to integrated capacitance evaluated by conventional cyclic voltammetry. The specific capacitance at the GC electrode varied with polarized potential and showed clear PZC (potential of zero charge), while the potential dependence of the capacitance at BDD was very small. The effects of the solvent and the electrolytic salt on the capacitance behavior were common for both electrodes. That is, the sizes of the solvent molecule and the electrolytic ion (cation) strongly affected the capacitance at these smooth-surface carbon electrodes.

  11. Representing Canadian Muslims: Media, Muslim Advocacy Organizations, and Gender in the Ontario Shari’ah Debate

    Directory of Open Access Journals (Sweden)

    Meena Sharify-Funk

    2009-01-01

    Full Text Available This paper analyzes a highly public conflict between two Muslim non-profit organizations, the Canadian Islamic Congress (CIC and the Muslim Canadian Congress (MCC, as it played out on the pages of Canadian newspapers and Internet websites. Sparked by profoundly divergent convictions about gender norms and fuelled by contradictory blueprints for “being Muslim in Canada”, this incendiary conflict was fanned by Canadian media coverage. Focusing especially, but not exclusively, on the 2003-2005 debate over Shari’ah-based alternative dispute resolution in Ontario, I will argue that the media have played a role in constructing internal Muslim debates and identity negotiations concerning what it means to be genuinely Canadian and authentically Muslim through controversy-driven journalism that has highlighted opposing ends of a liberal/progressive versus conservative/traditional axis in a search for “point/counter-point” views. Through short stories and commentaries on controversial topicsthat juxtapose two increasingly antagonistic organizational voices, the media have not merely reflected Muslim realities, but also helped to shape them and, more often than not, reinforce polarization between a “majority Muslim” culture seeking to secure space for itself within Canadian society and a “dissident Muslim” culture that seeks to consolidate external support for internal change.

  12. Media, journalism, objectivity

    Directory of Open Access Journals (Sweden)

    Vlajki Emil

    2013-01-01

    Full Text Available This is the text around the themes: Media and Journalism, are confronted two directions of opinions: humanism and elitism. Humanism believes that media and journalism must be metaphysically objective: able to tell the truth regardless of time, place and terms of events. Another approach, elitism, is connected with Hegel's philosophy of history. Hegel's conceptual apparatus includes: Idea, History dialectic, 'cunning mind,' self- development and self-realization. In this context, media and journalism are considered as organic unity, an inseparable part of some dialectical totality. More specifically media and journalism can be objective only if they defend concrete ideological assumptions of society to which they belong. Any other understanding of these two concepts is non-objective, mere moralizing and / or demagoguery.

  13. Determination of optical properties in heterogeneous turbid media using a cylindrical diffusing fiber

    For interstitial photodynamic therapy (PDT), cylindrical diffusing fibers (CDFs) are often used to deliver light. This study examines the feasibility and accuracy of using CDFs to characterize the absorption (μ a ) and reduced scattering (μ′ s ) coefficients of heterogeneous turbid media. Measurements were performed in tissue-simulating phantoms with μ a between 0.1 and 1 cm −1 and μ′ s between 3 and 10 cm −1 with CDFs 2 to 4 cm in length. Optical properties were determined by fitting the measured light fluence rate profiles at a fixed distance from the CDF axis using a heterogeneous kernel model in which the cylindrical diffusing fiber is treated as a series of point sources. The resulting optical properties were compared with independent measurement using a point source method. In a homogenous medium, we are able to determine the absorption coefficient μ a using a value of μ′ s determined a priori (uniform fit) or μ′ s obtained by fitting (variable fit) with standard (maximum) deviations of 6% (18%) and 18% (44%), respectively. However, the CDF method is found to be insensitive to variations in μ′ s , thus requiring a complementary method such as using a point source for determination of μ′ s . The error for determining μ a decreases in very heterogeneous turbid media because of the local absorption extremes. The data acquisition time for obtaining the one-dimensional optical properties distribution is less than 8 s. This method can result in dramatically improved accuracy of light fluence rate calculation for CDFs for prostate PDT in vivo when the same model and geometry is used for forward calculations using the extrapolated tissue optical properties.

The paper is based on two explorative studies: A multiple case study in ten Danish organizations and a single case study in a Danish bank. Based on the two...... studies it is proposed that it is possible to distinguish between three different types of communication arenas created by internal social media: A quiet arena, a knowledge sharing arena and a participatory communication arena. Internal social media does not in itself introduce participatory communication....... Different levels of communication might be reached in different types of organizations, and it is only when coworkers perceive a license to critique that organizations will actually develop participatory communication that has the ability to move the organization....

    2015-11-01

    Full Text Available Organic amendments have been widely used to stimulate the populations of predatory nematophagous fungi (PNF in soil; however, the use of organic amendments has produced inconsistent results in the control of parasitic nematodes. The inconsistencies have been partially attributed to the chemical composition of the organic amendments, specifically to carbon and nitrogen contents. Therefore, to know the carbon preferences of these fungi could be helpful to promote the predatory phase of the PNF in soil. The aim of this study was to determine the growth of native PNF strains from Costa Rica in diverse carbon sources. The PNF Arthrobotrys oligospora and Candelabrella musiformis were grown in artificial culture media containing the following carbon sources: cellulose, chitin, pectin, starch, and skim milk. The growth rate developed by the PNF in each one of the culture media was determined and compared. The growth rates developed by both fungal species followed the next order: cellulos e>chitin>pectin>starch>skim milk. Significant differences in the growth rates developed by the fungal strains were detected only in culture medium containing cellulose, in comparison with culture media containing other carbon sources. In culture medium containing cellulose both A. oligospora and C. musiformis grew faster with respect to the other culture media, but A. oligospora strains grew faster in comparison with C. musiformis strains. Both fungal species developed the lowest growth rates in culture media containing starch and skim milk.

    Most organizations have an existing policy for interactions with the media. This policy often requires that interactions be with or through a professional group of public information officers or the Office of Public Affairs. This policy tends to give individual members of an organization the belief that they are not responsible or in some instances, even allowed to interact with the media. To achieve good media relationships and/or coverage, individual interactions are necessary and required. The guidelines for media interactions provided in the Federal Emergency Management Agency (FEMA) sponsored Radiological Emergency Response course are relatively straightforward and simple to adopt

    Full Text Available The community of endophytic fungi associated with Acer ginnala, a common tree in northeastern China, was investigated. Four media, PDA, Czapek's, WA and Sabouraud's, were used to inoculate explants from seeds, annual twigs and perennial twigs (xylem and bark. Media strongly affected the isolated species number, but not colonization frequency (CF or isolation frequency (IF. To investigate media effect further, a Principal Component Analysis (PCA was done. As a result, two components accounted for 86.502% of the total variance were extracted. These two components were named as PDA-determined factor (accounted for 45.139% of the total variance and Czapek's-determined factor (accounted for 41.363% of the total variance, respectively. This result suggested that only two media, PDA and Czapek's, could be used instead of all four media in this study without affecting the isolation results significantly. In total, ten taxa were isolated in this study. Alternaria sp., Phomopsis sp., Neurospora sp. and Phoma sp. were dominant endophytes while Pleosporales Incertae Sedis sp., Cladosporium sp., Trichoderma sp. and Epicoccum sp. were rare taxa. Different tissues/organs had different endophyte assemblages. All tissue/organ pairs had low Bray-Curtis indices (<0.3 except for bark and annual twigs (0.63. Compared to perennial twigs, annual twigs had a lower taxon number, lower isolate number, lower endophyte dominance and diversity indices. Seeds had distinct assemblage, lower similarity and similar low diversity indices to annual twigs. These results suggested that tissue type determines the endophyte assemblage while age determines the diversity.

    The complexity of governing has increased with the Internet's introduction of social media. Boards need to be aware of social media impact upon external stakeholder relations, as well as legal responsibilities within the organization. This paper outlines the various implications of social media that a board needs to consider. A governance framework is used to help put the issues in perspective. The conclusion is that boards need to take social media seriously and ensure that their organization has a social media risk mitigation strategy for external communications, as well as eDiscovery. Various other strategies and tactics are suggested to help boards address the challenge.

    2013-01-01

    The main focus of this study was to investigate spectroscopic properties, stoichiometric ratios, physicochemical parameters, polarity and photostability behaviors of newly synthesized chalcone dye in organized media. The chalcone dye, 1-(2,5-Dimethyl-thiophen-3-yl)-3-(9-etnyl-9H-carbazol-3-yl)-propenone (DTEP), was prepared by the reaction of carbazole aldehyde with 3-acetyl-2,5-dimethythiophene. Data obtained from FT-IR, 1 H-–NMR, 13 C-NMR and elemental analysis were consistent with chemical structure of newly prepared DTEP. Increases in fluorescence intensities of DTEP with cetyltrimethyl ammonium bromide (CTAB) were observed. In comparison of fluorescence intensities for DTEP with CTAB, reductions in fluorescence intensities for DTEP with sodium dodecyl sulfate (SDS) were noticed under the same experimental and instrumental conditions. Additionally, Benesi–Hildebrand method was applied to determine stoichiometric ratios and association constants of DTEP with CTAB and SDS. Stern–Volmer plot was used in order to further confirm the stoichiometric ratio and association constant of DTEP with SDS. Physicochemical parameters such as singlet absorption, molar absorptivity, oscillator strength, dipole moment and fluorescence quantum yield of DTEP were also determined. Fluorescence polarity study displayed that DTEP was sensitive to the polarity of the microenvironment provided by different solvents. Finally, fluorescence steady-state measurements revealed that DTEP has high photostability against photobleaching. -- Highlights: ► Mechanistic understanding of molecular structure of newly synthesized chalcone dye. ► Exploring spectral behaviors and physicochemical parameters of chalcone dye. ► Determination of stoichiometric ratios and association constants of chalcone dye. ► Determination of fluorescence quantum yield in different solvents. ► High photostability against photobleaching of chalcone dye was observed

    Vapours of organic matters were determined qualitatively employed with ultraviolet-visible absorption spectroscopy. Vapours of organic matters were detected using ultraviolet-visible spectrophotometer employing polyethylene film as medium, the ultraviolet and visible absorption spectra of vegetable oil vapours of soybean oil, sunflower seed oil, peanut oil, rapeseed oil, sesame oil, cotton seed oil, tung tree seed oil, and organic compound vapours of acetone, ethyl acetate, 95% ethanol, glacial acetic acid were obtained. Experimental results showed that spectra of the vegetable oil vapour and the organic compound vapour could be obtained commendably, since ultra violet and visible spectrum of polyethylene film could be deducted by spectrograph zero setting. Different kinds of vegetable oils could been distinguished commendably in the spectra since the λ(max), λ(min), number of absorption peak, position, inflection point in the ultra violet and visible spectra obtained from the vapours of the vegetable oils were all inconsistent, and the vapours of organic compounds were also determined perfectly. The method had a good reproducibility, the ultraviolet and visible absorption spectra of the vapours of sunflower seed oil in 10 times determination were absolutely the same. The experimental result indicated that polyethylene film as a kind of medium could be used for qualitative analysis of ultraviolet and visible absorption spectroscopy. The method for determination of the vapours of the vegetable oils and organic compounds had the peculiarities of fast speed analysis, well reproducibility, accuracy and reliability and low cost, and so on. Ultraviolet and visible absorption spectrum of organic vapour could provide feature information of material vapour and structural information of organic compound, and provide a novel test method for identifying vapour of compound and organic matter.

    Full Text Available Emotions importance increases even more in the context of the national security agencies. Since their mission is to protect and defend the citizens against attacks and also to provide leadership and justice services to other agencies and partners, the aim of the information they post on social media should be twofold: on the one hand, it should reflect the attitudes, values and beliefs, supported by the institution, and on the other hand, it should have an impact on citizens feeling of security. But, do they manage to meet these demands? Are they focusing on impressing the audience or they concentrate on sharing specific emotions? Is it a marketing strategy or a knowledge strategy? Starting from these, the purpose of this research is to set a nexus between emotions and the use of social media by the national security organizations. In other words, we aim (i to determine the main types of emotions, (ii to establish whether these are shared within the social media platforms, (iii to identify the purpose for which the national security organizations use social media, (iv to determine whether social media could serve as Ba for the national security organizations. In order to achieve these objectives, we employ an ethic approach and develop a longitudinal study based on quantitative and qualitative content analysis. The results prove that social media platforms may serve as Ba since they appear as a shared space which fosters individual and collective knowledge creation and sharing. The national security agencies  use social media platforms for combining the classical four types of Ba: originating Ba (it shares its emotions, feelings and thoughts through its posts, interacting Ba (through the generated reactions and comments, it ensures the development of shared models and the conversion of tacit knowledge into explicit knowledge, cyber Ba (by fostering the virtual interaction among its followers and exercising Ba (by facilitating the creation of

    In the event of an emergency, media relation should be considered as one of the most important functions in emergency management. Individuals should be trained to be able to provide factual information to the media and the citizens during nuclear emergencies. Media can be also acquainted with the scope, ways and means of providing information related to nuclear emergencies during the predefined and regular media training or workshops, or as a part of regular training routine of involved organizations and institutions. This paper is through various approaches trying to present one of the possible ways that media and public relation can be treated during the emergencies and inside the developed emergency plans and procedures. It also represents an idea, based on the authors' experience, on a way in which things can be organized in the Croatian Technical Support Center when it comes to the media/public relation issue.

    We aimed to determine the characteristic adverse events (AEs) of iodinated contrast media (IOCM) and to compare the safety profiles of different IOCM. This study used the database of AEs reports submitted by healthcare professionals from 15 Regional Pharmacovigilance Centers between June 24, 2009 and December 31, 2010 in Korea. All reports of IOCM, including iopromide, iohexol, iopamidol, iomeprol, ioversol, iobitridol and iodixanol, were analyzed. Safety profiles were compared between different IOCM at the system organ level using the proportional reporting ratio (PRR) and 95% confidence interval (95% CI). Among a total of 48,261 reports, 6,524 (13.5%) reports were related to the use of IOCM. Iopromide (45.5%), iohexol (16.9%), iopamidol (14.3%) and iomeprol (10.3%) were identified as frequently reported media. 'Platelet, bleeding & clotting disorders' (PRR, 29.6; 95%CI, 1.9-472.6) and 'urinary system disorders' (PRR, 22.3; 95% CI, 17.1-29.1) were more frequently reported for iodixanol than the other IOCM. In conclusion, the frequency of AEs by organ class was significantly different between individual media. These differences among different IOCM should be considered when selecting a medium among various IOCM and when monitoring patients during and after its use to ensure optimum usage and patient safety.

    Polarization-sensitive optical coherence tomography (PS-OCT) was used to characterize completely the polarization state of light backscattered from turbid media. Using a low-coherence light source, one can determine the Stokes parameters of backscattered light as a function of optical path in turbid media. To demonstrate the application of this technique we determined the birefringence and the optical axis in fibrous tissue (rodent muscle) and in vivo rodent skin. PS-OCT has potentially useful applications in biomedical optics by imaging simultaneously the structural properties of turbid biological materials and their effects on the polarization state of backscattered light. This method may also find applications in material science for investigation of polarization properties (e.g., birefringence) in opaque media such as ceramics and crystals. copyright 1999 Optical Society of America

    The dissolution of Ag (citrate, gelatin, polyvinylpyrrolidone and chitosan coated), ZnO, CuO and carbon coated Cu nanoparticles (with two nominal sizes each) has been studied in artificial aqueous media, similar in chemistry to environmental waters, for up to 19 days. The dissolved fraction was determined using DGT (Diffusion Gradients in Thin films), dialysis membrane (DM) and ultrafiltration (UF). Relatively small fractions of Ag nanoparticles dissolved, whereas ZnO dissolved nearly completely within few hours. Cu and CuO dissolved as a function of pH. Using DGT, less dissolved Ag was measured compared to UF and DM, likely due to differences in diffusion of organic complexes. Similar dissolved metal concentrations of ZnO, Cu and CuO nanoparticles were determined using DGT and UF, but lower using DM. The results indicate that there is a need to apply complementary techniques to precisely determine dissolution of nanoparticles in aqueous media. - Highlights: • Three different techniques used simultaneously to measure NPs dissolution. • ZnO-NPs are the most soluble, followed by CuO-NPs, carbon coated Cu-NPs and Ag-NPs. • Dissolution is an important process affecting the fate of nanoparticles. • Complementary techniques are needed to precisely determine dissolution of NPs. - Dissolution of several types of nanoparticles was examined in aqueous media using three complementary techniques

    The occurrence of aquatic pollution is an inevitable environmental impact resulting from human civilization and societal advancement. Either from the natural or anthropogenic sources, the aqueous contaminants enter the natural environment and aggravate its quality. To assure the aquatic environment quality, the attached-growth biological degradation is often applied to removing organic contaminants by introducing contaminated water into a porous media which is covered by microorganism. Additionally, many natural aquatic systems also form such similar mechanism to increase their self-purification capability. To better understand this transport phenomenon and degradation mechanism in the biofilm for future application, the mathematic characterization of organic contaminant diffusion within the biofilm requires further exploration. The present study aimed to formulate a mathematic representation to quantify the diffusion of the organic contaminant in the biofilm. The BOD was selected as the target contaminant. A series of experiments were conducted to quantify the BOD diffusion in the biofilm under the conditions of influent BOD variation from 50 to 300 mg/L, COD:N:P ratios of 100:5:1 and 100:15:3, with or without auxiliary aeration. For diffusion coefficient calculation, the boundary condition of zero diffusion at the interface between microbial phase and contact media was assumed. With the principle of conservation of mass, the removed contaminants equal those that diffuse into the biofilm, and eq 1 results, and the diffusion coefficient (i.e., eq 2) can be solved through calculus with equations from table of integral. ∂2Sf- Df ∂z2 = Rf (1) --(QSin--QSout)2Y--- Df = 2μmaxxf(Sb + Ks ln-Ks-) Sb+Ks (2) Using the obtained experimental data, the diffusion coefficient was calculated to be 2.02*10-6 m2/d with influent COD of 50 mg/L at COD:N:P ratio of 100:5:1 with aeration, and this coefficient increased to 6.02*10-6 m2/d as the influent concentration increased to

  3. Social Media and Bullshit

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available To understand the role of social media in society, we have to understand how social media are understood. We need to analyze how different actors and organizations see and think about technology, the forms of knowledge that people draw on as they make sense of, develop, and use social media. Central among these is bullshit. This short essay discusses bullshit as defined by the philosopher Harry Frankfurt as statements made with little or no concern for their truth-value or justification and argues that social media are accompanied by unusually large amounts of bullshit for two reasons. First, they confront us with epistemological problems and are hard to understand. Second, there is a large demand for knowledge about what they mean, a powerful political economy that generates a lot of statements about social media, including substantial amounts of bullshit. Given the rapid development of social media and their growing importance, this is unlikely to change in the near future. Bullshit is here to stay, and we need to take it seriously intellectually and analytically to understand social media.

    Presented are calculated dependences for adiabatic compressibility, isoentropy coefficient and thermodynamic sound velocity of a two-phase media with homogeneous disperse structure being in a state of equilibrium. The character of the change of the values mentioned for vapor water media at the change of vapor mass composition in the mixture from zero to 1 is shown. Comparison of the calculated data as to dependences obtained with the experimental ones for critical regimes of vapor-water flow outflow through short and long cylindrical channels with sharp entrance rims. The calculation error does not exceed approximately 12%. Analysis of the results obtained showed that at outflow through short channels of metastable vapor liquid flow the main characteristics, like at outflow through long channels, are determined by the pressure in the exit cross section, mass vapor content and specific volume of the mixture, which are calculated with account for real overheating of the liquid to the exit cross section. At critical regime of outflow through the very long channels, when one can not neglect hydraulic resistance in the channel and the process is not isoentropic, the pressure and mass vapor content in the exit cross section also unambiguously determine the value of adiabatic compressibility of two-phase media, sound velocity and isoentropy coefficient in the cross section. Conclusion is made that the dependences obtained can be used with sufficient for practical purposes accuracy when solving different engineering problems, as well as for the calculations of the mixture consumption at flow of the reactor contours NAI with WWR

    Focusing on stochastic porous media equations, this book places an emphasis on existence theorems, asymptotic behavior and ergodic properties of the associated transition semigroup. Stochastic perturbations of the porous media equation have reviously been considered by physicists, but rigorous mathematical existence results have only recently been found. The porous media equation models a number of different physical phenomena, including the flow of an ideal gas and the diffusion of a compressible fluid through porous media, and also thermal propagation in plasma and plasma radiation. Another important application is to a model of the standard self-organized criticality process, called the "sand-pile model" or the "Bak-Tang-Wiesenfeld model". The book will be of interest to PhD students and researchers in mathematics, physics and biology.

It is a community engagement project conducted in the Tshwane community. Community engagement (CE as a planned process with the specific purpose of working with identified groups of people in the community to address issues affecting their well-being. The CE project SME skills transfer workshops are aimed at expanding involvement with the community. The benefits of social media seem to be ignored by most SMEs however; challenges prevent SME owners from using the tool effectively. A survey study method of research design has been selected for the research. The sample for the study comprised 200 SME owners who currently manage small businesses in the Tshwane area. The conducted research recommends that social media can be cost effective if the SMEs make use of their social networks and use best practises that enable them to get their adverts or posts shared across social networks. The conducted research also recommends that SMEs with limited resources start with social media and YouTube as a marketing tool, as the learning curve is low and cost involved is almost nil.

    The Eustachian tube (ET) is responsible for the ventilation, protection, and cleaning of the middle ear. ET dysfunction plays an important role in the pathogenesis of otitis media cases, and thus the treatment and prognosis of these cases is extremely dependent on adequate ET function, which can ultimately affect the success rate of middle ear reconstruction practices. Data research on the ET’s ventilation function is needed to ensure the success of therapy and surgery treatments in the case of Chronic Suppurative Otitis Media (CSOM) patients. This study aims to investigate ET ventilation functioning in benign type CSOM and non-otitis media subjects and to develop another modality to measure ET ventilation functioning in patients with intact and perforated tympanic membranes. A comparative cross-sectional study of 36 benign type CSOM patients and 80 non-otitis media subjects will be conducted using sonotubometry and the rated parameter measurements of ET opening frequency, amplitude and ET opening duration. Malfunctioning ventilation of the ET is more common among benign type CSOM subjects (47%) than among non-otitis media subjects (18.75%). There is a significant difference (p = 0.002) between the ET ventilation functioning of benign type CSOM subjects and non-otitis media subjects—benign type CSOM subjects have rates of malfunctioning ET ventilation that are 3.88 times higher than those of non-otitis media subjects. Patients with benign type CSOM are more likely to experience malfunctioning ET ventilation than are non-otitis media subjects.

    2018-06-01

    Taking into account that a key determinant in public approval of vaccinations is how the media constructs and frames messages about vaccination programmes, our aim is to review communication studies exploring media coverage of vaccines within traditional media venues. Using a registered protocol (PROSPERO: 42017072849), a systematic review was conducted that searched in three international electronic databases (PubMed, Scopus, and the International Bibliography of Social Science) for articles published between 2007 and 2017 following content-analysis methods. The characteristics and outcomes were systematically identified and described. The search yielded 24 eligible studies that were further analysed in the review. Media coverage of vaccines has been largely studied during the last decade. Findings revealed that 62% ( n = 15) of studies analysed the human papillomavirus vaccine, 87% ( n = 21) examined newspapers, and 62% ( n = 15) examined North American media. In relation to media content analyses, 75% found negative messages on vaccines and 83% identified a lack of accurate information. This systematic review suggests an agenda for further research. There is a significant need to analyse other types of traditional media beyond newspapers. Future studies should focus on other geographical areas such as low-income countries and on analysing visual materials and digital media. We found that negative messages and inaccurate information are common in media coverage on vaccines; therefore, further research focusing on these topics is needed. Officials in public health organizations should develop a close collaboration with the media to improve public communication on vaccines.

    Health campaigns have struggled to gain traction with young adults using social media, even though more than 80% of young adults are using social media at least once per day. Many food industry and lifestyle brands have been successful in achieving high levels of user engagement and promoting their messages; therefore, there may be lessons to be learned by examining the successful strategies commercial brands employ. This study aims to identify and quantify social media strategies used by the food industry and lifestyle brands, and health promotion organizations across the social networking sites Facebook and Instagram. The six most engaging posts from the 10 most popular food industry and lifestyle brands and six health promotion organizations were included in this study. A coding framework was developed to categorize social media strategies, and engagement metrics were collected. Exploratory linear regression models were used to examine associations between strategies used and interactions on Facebook and Instagram. Posts from Facebook (143/227, 63.0%) and Instagram (84/227, 37.0%) were included. Photos (64%) and videos (34%) were used to enhance most posts. Different strategies were most effective for Facebook and Instagram. Strategies associated with higher Facebook interactions included links to purchasable items (beta=0.81, 95% CI 0.50 to 1.13, PInstagram (beta=0.50, 95% CI 0.05 to 0.95, P=.03). Instagram interactions were negatively associated with weight loss (beta=-1.45, 95% CI -2.69 to -0.21, P=.02) and other content (beta=-0.81, 95% CI -1.57 to -.06, P=.04) compared with food content. Health promotion professionals and organizations can improve engagement using positive messaging and tailoring posts appropriate for different social media channels. ©Karen Michelle Klassen, Emily S Borleis, Linda Brennan, Mike Reid, Tracy A McCaffrey, Megan SC Lim.

    Full Text Available The demand for organic products is growing, however in Turkey although the interest to organic products has grown; the growth of demand is relatively low. So it is important for producers of organic products to understand who the organic customers are, and what are their attitudes and behaviors regarding organic food products as well as why people do not prefer them. This is the main aim of this article. This study presents the results of a survey regarding consumer perceptions of organic foods in Turkey. The survey was conducted to determine consumer attitudes towards organic foods and the reasons for consumption or non-consumption of organic foods. A total of 882 consumers that makes food shopping for their families, living in İzmir participated the research. The results of the survey revealed that health issue is an important consideration in the consumption of organic products, however respondents stated that they find organic products expensive and hard to find everywhere, and they have some doubts about the reliability of the organic foods. Also five types of behaviour regarding organic food consumption behavior have been identified. The findings have practical implications especially for governments. More support and education should be given to organic producers so that supply of organic food products would increase, and there should be strict control on those products as to reduce consumers’ negative attitudes.

    Full Text Available It has previously been proposed that agency theory (principal-agent approach might be applied to media organizations to understand how media owners make sure that their companies are managed according to their wishes. Thus, the purpose of the present study was to investigate: a whether agency theory is applicable to three Icelandic media companies, and b how the theory manifests itself in the management practices of these companies. The media companies that were examined were: the Icelandic National Broadcasting Service (RÚV ohf., 365 miðlar ehf. and Árvakur hf. Qualitative interviews were conducted with three editors-in-chief, two CEOs/publishers, the director general of RÚV and the news director of RÚV in May of 2012. Two of the interviewees were also part- owners of the media companies. The results indicated that it is, indeed, possible to analyze management practices of media organizations from the perspective of agency theory. However, it varies how much the companies are driven by profit maximization, for instance – on which agency theory places an optimum emphasis. The media house 365 miðlar ehf. turned out to be the best example of how the underlying constructs of agency theory are incorporated into the management practices of a media organization.

    The present qualitative study explores advocates' opinions of misinformation about human trafficking in the media and describes advocates' strategies to counter the misinformation presented by the media. Thus, 15 advocates who work against human trafficking in Chicago-based nonprofit organizations participated in semistructured interviews about their opinions and strategies. Data were analyzed using thematic content analysis. The present study identifies specific misperceptions of human trafficking in the media, highlights advocates' opinions of this misinformation, and discusses advocates' strategies to counteract inaccurate media, adding support to the role of media advocacy. Advocates note how media images shape and perpetuate stereotypes of trafficking through glamorizing sex work and sensationalizing stories that are most often international depictions of trafficking. Advocates report media generally shares only a piece of the story, simplifying the stories of survivors and the issue of human trafficking. Advocates critique media perpetuating these misperceptions for how they may contribute to policies and programs which fail to address structural factors that create vulnerabilities to be trafficked and the multisystem needs of survivors. However, advocates also note misperceptions can be counteracted by producing sensitive, informed media through social platforms. Advocates share their strategies counteracting misinformation through engaging in informative conversations, utilizing social media to educate, and promoting media messages of survivor agency. Research, clinical, and policy implications are also discussed. The present study emphasizes the importance of decision makers and service providers being critical consumers of media and to assess how media portrayals may (or may not) inform their understanding and response to the issue.

    BACKGROUND: To increase the available pool of organ donors, Ontario introduced donation after circulatory determination of death (DCD) in 2006. Other jurisdictions have reported a decrease in donations involving neurologic determination of death (NDD) after implementation of DCD, with a drop in organ yield and quality. In this study, we examined the effect of DCD on overall transplant activity in Ontario. METHODS: We examined deceased donor and organ transplant activity during 3 distinct 4-year eras: pre-DCD (2002/03 to 2005/06), early DCD (2006/07 to 2009/10) and recent DCD (2010/11 to 2013/14). We compared these donor groups by categorical characteristics. RESULTS: Donation increased by 57%, from 578 donors in the pre-DCD era to 905 donors in the recent DCD era, with a 21% proportion (190/905) of DCD donors in the recent DCD era. However, overall NDD donation also increased. The mean length of hospital stay before declaration for NDD was 2.7 days versus 6.0 days before withdrawal of life support and subsequent asystole in cases of DCD. The average organ yield was 3.73 with NDD donation versus 2.58 with DCD (p organs from DCD donors were successfully transplanted. From the pre-DCD era to the recent DCD era, transplant activity in each era increased for all solid-organ recipients, including heart (from 158 to 216), kidney (from 821 to 1321), liver (from 477 to 657) and lung (from 160 to 305). INTERPRETATION: Implementation of DCD in Ontario led to increased transplant activity for all solid-organ recipients. There was no evidence that the use of DCD was pre-empting potential NDD donation. In contrast to groups receiving other organs, heart transplant candidates have not yet benefited from DCD. PMID:28947546

    Web 2.0 media (eg, Facebook, Wikipedia) are considered very valuable for communicating with citizens in times of crisis. However, in the case of infectious disease outbreaks, their value has not been determined empirically. In order to be able to take full advantage of Web 2.0 media in such a situation, the link between these media, citizens' information behavior, and citizens' information needs has to be investigated. The goal of our study was to assess citizens' Web 2.0 media use during an infectious disease outbreak and to determine which Web 2.0 medium is used for which goal. With this information, we wanted to formulate recommendations for health organizations that consider using Web 2.0 media as part of their communication strategy during an infectious disease outbreak. A total of 18 student participants kept an information diary for 4 weeks during the 2011 enterohemorrhagic E. coli (EHEC) outbreak in Germany. Of them, 9 lived at the epicenter of the outbreak and 9 of them at some distance. The diaries were supplemented by a qualitative pre-survey (demographics) and postsurvey (questioning their satisfaction with information provision during the outbreak). The Internet appeared to be the most popular medium for passively receiving EHEC-related information, with news websites and websites of newspapers as the most consulted sources. Twitter was used for receiving information to a small degree, while Facebook played virtually no role. Participants indicated that they thought information posted on Twitter or Facebook was not reliable or was out of place. When actively seeking information, online newspapers and wikis were important sources. Several causes for (dis)satisfaction with information provision were uncovered: source credibility, contradicting messages, and a need for closure. During an infectious disease outbreak, our small sample of students did not see social media (like Facebook and Twitter) as suitable or reliable sources for communicating

  10. Social Media Rhetoric of the Transnational Palestinian-led Boycott, Divestment, and Sanctions Movement

    Directory of Open Access Journals (Sweden)

    Jennifer Hitchcock

    2016-02-01

    Full Text Available This article uses rhetorical analysis to determine the effectiveness and characteristics of social media usage by the Boycott, Divestment, and Sanctions (BDS movement targeting Israel. Hundreds of local student, community, and religious groups in the United States use social media platforms such as Twitter and Facebook to promote BDS discourse and organize local BDS-related events. Even though social media platforms are important for an international movement composed of a very dispersed population, with millions of Palestinians also living under military occupation, the history of traditional media use during the First Intifada also suggests that social media are not necessary for mobilizing Palestinians at the local level. A preliminary rhetorical analysis of several BDS-related Facebook pages and Twitter accounts reveals that the BDS movement’s social media usage functions similarly in some ways to other contemporary mass movements by facilitating on-the-ground actions and delivering useful information to supporters. BDS movement social media discourse, however, does not establish the same level of emotional connection or interactivity with audiences as some other recent movements have, but these limitations can be partly explained by the unique political, material, and rhetorical constraints of the situation.

    2008-12-01

    The main purpose of the International Atomic Energy Agency (IAEA) Public Awareness Strategies for Tissue Banks is to provide guidance on organizing and running awareness campaigns, in order to consolidate tissue banking activities. Within the IAEA Public Awareness Strategies for Tissue Banks, there are two important topics, which need to be singled out due to their importance for a successful public and professional awareness campaign. These are the selection of the audiences and the organization of media events within a Communication Strategy. The experience in the field of tissue banking in several countries has shown that interaction between the public, the professional health care staff, the media and the tissue bank personnel is essential if the activities of the banks are to be successful. It must be emphasized however, that any public and professional awareness strategy will not be successful, unless it is considered as part of an integrated system that is adopted by the concerned Government.

    2016-06-01

    Full Text Available The deeply engrained nature of social media in modern life have provided ease of access to information and speed of use within almost every aspect of a person’s life. These same benefit are also available to terrorists and their organizations. The same technology that allows for a globalized world to interact without regard for distance or physical location is also utilized, exploited and adapted to by terrorist organizations to conduct operations, reach candidates and ensure organizational longevity. This article takes the position of observer of these advancements with the end goal of informing counter-violent extremism strategists of the advances that terrorist groups have already made in digital technology; and where the priority of intervention strategies should be aimed. Further, this is intended to guide policy makers to embrace and utilize digital technologies as a mechanism to carry counter-radicalization and counter-violent extremism interventions through the same digital potential and reach the same audiences as terrorist organizations. What appears strongly apparent is that social media will not abate from its intrinsic position graphed into daily life. This means that counter-terrorism, counter-radicalization and counter-violent extremism strategies must take up the same technology in order to effectively discredit and nullify extremist groups – a digital problem needs a digital solution.

    The fluorescent property of the aqueous solution of a metal organic framework (MOF) of Mn(II), having a sedimentary rocks like microstructure in solid-state, has been investigated. The luminescent feature of the the aqueous solution of MOF has been employed for studying the interactions of MOF with different surfactants including neutral, cationic, and anionic types in water medium. Interestingly, the MOF can very selective sense Triton X-100 based micelle in water medium. During the sensing process the fluorescent monomer of the MOF gets accommodated at the palisade layer of Triton X-100 in water medium and this has also been justified by simple fluorescence spectral and FE-SEM microstructural analysis. Thus, a MOF of Mn(II) can act as a selective fluorescent sensor for Triton X-100 based organized medium in water. - Highlights: • Microstructural and crystallographic studies of a water-soluble MOF are performed. • The luminescent property of MOF in water medium is explored. • The interaction between Triton X-100 and the MOF in water medium is studied by fluorometric and microstructural analysis. • The MOF acts as a selective fluorometric sensor for the Triton X-100 based organized media in water. • The monomer of MOF presents in the Triton X-100 micelle in water.

    Social media and electronic news media activity are an important source of information for the general public. Yet, there is a dearth of research exploring the use of Twitter and electronic news outlets during significant worldly events such as the recent Ebola Virus scare. The purpose of this article is to investigate the use of Twitter and electronic news media outlets in communicating Ebola Virus information. A cross-sectional survey of Twitter data and Google News Trend data from 30 September till 29 October, 2014 was conducted. Between 30 September and 29 October, there were approximately 26 million tweets (25,925,152) that contained the word Ebola. The highest number of correlated activity for Twitter and electronic news outlets occurred on 16 October 2014. Other important peaks in Twitter data occurred on 1 October, 6 October, 8 October, and 12 October, 2014. The main influencers of the Twitter feeds were news media outlets. The study reveals a relationship between electronic news media publishing and Twitter activity around significant events such as Ebola. Healthcare organizations should take advantage of the relationship between electronic news media and trending events on social media sites such as Twitter and should work on developing social media campaigns in co-operation with leading electronic news media outlets (e.g. CNN, Yahoo, Reuters) that can have an influence on social media activity. © The Author(s) 2015.

    We describe a fast, accurate method for determination of the optical coefficients of 'semi-infinite' and 'infinite' turbid media. For the particular case of time-resolved reflectance from a biological medium, we show that a single Monte Carlo simulation can be used to fit the data and to derive the absorption and reduced scattering coefficients. Tests with independent Monte Carlo simulations showed that the errors in the deduced absorption and reduced scattering coefficients are smaller than 1% and 2%, respectively. (author)

    Matikainen, Janne; Huovila, Janne

    Social media has brought about a major change in communication. Besides ordinary people, the change applies to organizations and public authorities. In the social media, the public becomes an active player and content provider. With social media, communication will become increasingly media-centered. The change in communication scenery has challenged traditional expertise. On the other hand, social media also opens up many possibilities for the establishment of expertise and health communication. Within the social media, communities can become significant sites for the production of knowledge and expertise. They may generate useful activity as regards the combination of health information activities and everyday life, but sometimes they can also become a cradle of false information. In its various forms, social media provides a versatile forum for health communication, where people can be met interactively.

    Kushner, Mark Jay [University of Michigan

    2014-07-10

    In this research project, the interaction of atmospheric pressure plasmas with multi-phase media was computationally investigated. Multi-phase media includes liquids, particles, complex materials and porous surfaces. Although this investigation addressed fundamental plasma transport and chemical processes, the outcomes directly and beneficially affected applications including biotechnology, medicine and environmental remediation (e.g., water purification). During this project, we made advances in our understanding of the interaction of atmospheric pressure plasmas in the form of dielectric barrier discharges and plasma jets with organic materials and liquids. We also made advances in our ability to use computer modeling to represent these complex processes. We determined the method that atmospheric pressure plasmas flow along solid and liquid surfaces, and through endoscopic like tubes, deliver optical and high energy ion activation energy to organic and liquid surfaces, and produce reactivity in thin liquid layers, as might cover a wound. We determined the mechanisms whereby plasmas can deliver activation energy to the inside of liquids by sustaining plasmas in bubbles. These findings are important to the advancement of new technology areas such as plasma medicine

    The purpose of this review paper is to explore the impacts of social media on healthcare organizations, clinicians, and patients. This study found that healthcare organizations, clinicians and patients can benefit from the use of social media. For healthcare organizations, social media can be used primarily for community engagement activities such as fundraising, customer service and support, the provision of news and information, patient education, and advertising new services. The study also found that the most widely used social media venues for physicians were online communities where physicians can read news articles, listen to experts, research new medical developments, network, and communicate with colleagues regarding patient issues. Patients can benefit from the use of social media through education, obtaining information, networking, performing research, receiving support, goal setting, and tracking personal progress. Future research should further examine other financial, technological, informational, ethical, legal, and privacy issues surrounding the use of social media in healthcare.

    2014-02-01

    Full Text Available Gas in scattering media absorption spectroscopy (GASMAS has been extensively studied and applied during recent years in, e.g., food packaging, human sinus monitoring, gas diffusion studies, and pharmaceutical tablet characterization. The focus has been on the evaluation of the gas absorption pathlength in porous media, which a priori is unknown due to heavy light scattering. In this paper, three different approaches are summarized. One possibility is to simultaneously monitor another gas with known concentration (e.g., water vapor, the pathlength of which can then be obtained and used for the target gas (e.g., oxygen to retrieve its concentration. The second approach is to measure the mean optical pathlength or physical pathlength with other methods, including time-of-flight spectroscopy, frequency-modulated light scattering interferometry and the frequency domain photon migration method. By utilizing these methods, an average concentration can be obtained and the porosities of the material are studied. The last method retrieves the gas concentration without knowing its pathlength by analyzing the gas absorption line shape, which depends upon the concentration of buffer gases due to intermolecular collisions. The pathlength enhancement effect due to multiple scattering enables also the use of porous media as multipass gas cells for trace gas monitoring. All these efforts open up a multitude of different applications for the GASMAS technique.

    Full Text Available The continuity and the success of organizations appear increasingly associated with the incorporation of social media. The success depends of the structural and procedural changes that the organization has to make. Today, social media are the new digital marketing tools that help in the processes of communication. Companies need to understand that they are no longer the exclusive owners of the relation of consumers with their products/services; instead, the survival of the organizations depends of the effective utilization of the social media. Creative and innovative solutions are not necessarily too expensive and the internet ends up being one of the best marketing tools available for the organizations. In a more transparent and dynamic world, consumers trust other people to provide advice and recommendations about products and services more and more through social media and it is important to know how and why social media influence organizations. This study analyzes through a literature review the current importance of social media for digital marketing communication and shows a case study on traditional shops that use social media to obtain competitive advantages over shopping centers in Funchal (Madeira, Portugal. To finish, the study proposes a new model of business for successful marketing strategies. Also, the article explains how to manage the changes associated and how collaborators need to get used to working in a wider and more dynamic community.

    Full Text Available The consumption of organic milk is increasing rapidly. However, the behaviour of organic milk consumers is still not enough investigated. The purpose of this study was to determine variables which influence the attitude towards organic milk consumption, as well as variables which influence the buying intention of organic milk. Thereat, factors such as positive opinion toward organic milk and food related lifestyle, as well as level of trust in home as in EU organic food label, objective knowledge and gender of respondents showed to have a significant influence on organic milk buying intention. More precisely, a significant and positive influence on buying intention of organic milk was observed considering the belief in positive aspects of organic milk, subjective knowledge, objective knowledge, and attitude towards buying organic milk. According to the results of this study recommendations for marketing practice and especially for communication policy might be created. Communication directed to female population should use classic advertising based on functional information, while the one directed to male population should use more emotional advertising. By using classic advertising education of consumers should be performed in order to promote benefits of organic milk in regards to conventional milk.

  3. Evaluation of Advertising Campaigns on Social Media Networks

    2018-03-01

    Full Text Available As the virtual environment is constantly changing, not only users’ informational and knowledge needs but also the means and channels of communication with customers applied by organizations change. There is a noticeable trend to move more and more advertising campaigns to social media networks because of the opportunities they provide to organizations and users, which results in the ever-increasing popularity of social media networks and a number of their users. Such a transition is explained by one of the main objectives organizations have: to inform their customers in an appropriate way and receive feedback on social media networks, which is difficult when traditional advertising channels and means are applied. Since advertising campaigns on social media networks are evolving rapidly, their assessment factors and methods, which receive controversial opinions in both scientific literature and practice, change too. Researchers assess and interpret the factors that influence the effectiveness of advertising campaigns on social media networks differently. Thus, a problem arises: how should we evaluate which approach is more capable of accurately and fully reflecting and conveying reality? In this research, this problem is studied by connecting approaches of different researchers. These approaches are linked to the effectiveness assessment of advertising campaigns on social media network aspects. To achieve the objective of this study, such research methods as analysis of scientific literature, multiple criteria and expert assessment (a structured survey and an interview were applied. During the study, out of 39 primary assessment factors, eight primary factors that influence the effectiveness of advertising campaigns on social media networks were identified: sales, content reach, traffic to website, impressions, frequency, relevance score, leads and audience growth.

    In the present contribution, the porous material modeling and micro-structural material parameters determination are scrutinized via the micro-dilatation theory. The main goal is to take advantage of the micro-dilatation theory which belongs to the generalized continuum media. In the first stage, the thermodynamic laws are entirely revised to reach the energy balance relation using three variables, deformation, porosity change and its gradient underlying the porous media as described in the micro-dilatation theory or so-called void elasticity. Two experiments over cement mortar specimens are performed in order to highlight the material parameters related to the pore structure. The shrinkage due to CO2 carbonation, porosity and its gradient are calculated. The extracted values are verified via 14C-PMMA radiographic image method. The modeling of swelling phenomenon of Delayed Ettringite Formation (DEF) is studied later on. This issue is performed via the crystallization pressure application using the micro-dilatation theory.

  7. Proton surface charge determination in Spodosol horizons with organically bound aluminum

    Skyllberg, Ulf; Borggaard, Ole K.

    1998-05-01

    Net proton surface charge densities were determined in O, E, Bh, and Bs horizons of a sandy till, Spodosol from Denmark, by means of acid-base titration combined with ion adsorption in 0.005 M Ca(NO 3) 2 and independent permanent charge determination. The release of organic anions exceeded the adsorption of NO 3-, resulting in a desorption of anions in all horizons. Data were found to obey the law of balance between surface charges and adsorbed ions only when charges pertaining to Al and organic anions released during the titration experiments were accounted for, in addition to charges pertaining the potential determining ions (PDI) H + and OH - and the index ions Ca 2+ and NO 3-. It was furthermore shown that the point of zero net proton charge (PZNPC) in soils highly depends on the concentration of organically bound Al. Approaches previously used in soils, in which adsorbed Al n+ has been ignored (i.e., considered equivalent to nH + as a PDI), resulted in a PZNPC of 4.1 in the Bs horizon. If instead organically bound Al was accounted for as a counter-ion similar to 3/2Ca 2+, a PZNPC of 2.9 was obtained for the same Bs horizon. Based on PZNPC values estimated by the latter approach, combined with a weak-acid analog, it was shown that organic proton surface charges buffered pH with a similar intensity in the O, E, Bh, and Bs horizons of this study. Because the acidity of Al adsorbed to conjugate bases of soil organic acids is substantially weaker than the acidity of the corresponding protonated form of the organic acids, the point of zero net proton charge (PZNPC) will increase if the concentration of organically adsorbed Al increases at the expense of adsorbed H. This means that PZNPC values determined for soils with unknown concentrations of organically adsorbed Al are highly operational and not very meaningful as references.

    2018-01-01

    Introduction Many societies and organizations are using social media to reach their target audience. The extent to which parents of patients with craniofacial anomalies use social media has yet to be determined. The goal of this study is to characterize and describe the use of social media by the parents of children with cleft lip and palate as it pertains to the care of their child. Materials and Methods Parents or guardian of all patients presenting for initial consultation regarding a child's congenital cleft anomaly were contacted by phone or mail to complete a survey regarding their use of social media vis-à-vis their child's cleft anomaly. Participants were asked to answer a 19-question survey. Results Thirty-two families were contacted and 25 surveys were completed. Ninety-two percent of respondents used social media to learn about their child's diagnosis. Facebook (76%) and blogs (24%) were the most commonly accessed social media outlets, followed by Instagram (8%). Education about the diagnosis and treatment of cleft pathology (87%) was the most common reason for accessing social media, followed by companionship and support (56%), and advice about perioperative care (52%). Almost half (43%) of parents used social media to obtain information on their caregiver and treatment team, and 26% of parents used information gained on social media to guide their decision on where to seek care. Conclusion Social media is a readily available resource, one that will certainly shape the experiences of our patients and families for years to come.

    1984-01-01

    In two long-term studies, the BACTEC radiometric system for detection of bacteremia was evaluated with three culture media each: (i) BACTEC media 6A (for aerobes) and 7B (for anaerobes) plus a thioglycolate medium and (ii) BACTEC media 6A, 7B, and 8A (hypertonic). In study 1, clinically significant isolates were identified in 1,873 (13.9%) of 13,432 blood cultures with all three media. The thioglycolate medium revealed 143 (1.1%) organisms not recovered from the 6A and 7B media. In study 2, isolates were identified in 1,135 (12.9%) of 8,759 cultures with all three media; 104 (1.2%) organisms were isolated only from the hypertonic medium. The increased yield of positive cultures in the three-medium system is likely due to the larger volume of blood cultured

    2014-08-01

    Full Text Available Several methods exist for determining soil organic carbon, and each one has its own advantages and limitations. Consequently, a comparison of the experimental results obtained when these methods are employed is hampered, causing problems in the comparison of carbon stocks in soils. This study aimed at evaluating the analytical procedures used in the determination of carbon and their relationships with soil mineralogy and texture. Wet combustion methods, including Walkley-Black, Mebius and Colorimetric determination as well as dry combustion methods, such as Elemental and Gravimetric Analysis were used. Quantitative textural and mineralogical (kaolinite, goethite and gibbsite analyses were also carried out. The wet digestion methods underestimated the concentration of organic carbon, while the gravimetric method overestimated. Soil mineralogy interfered with the determination of carbon, with emphasis on the gravimetric method that was greatly influenced by gibbsite.

    2010-01-01

    Full Text Available By accessing the content analysis of media archives, available both on the Internet presentations of the most significant and most influential media, press agencies, web search engines, and official public institutions, international government and non-government organizations, we will make an attempt to point to political conditioning, appearances and uses, as well as political etymology of the term Western Balkans. The attention will also be called to the fact that the term has its origin in Anglo-Saxon political and historiographical tradition, through the examples of its use, as well as to the similarities of political relations which bring to its applicability. By analyzing the content of media inscriptions, reports, documents, official announcements, authorial reviews and analyses, it came to a conclusion that Western Balkans occurs as a regional reference in particular historical and political circumstances and that geographical frames it is being used within, could be located outside the time frames and there are specified the particularities of its use. We will demonstrate that through the analysis of the political context and media usage, Western Balkans could be interpreted on more than one level. Western Balkans can at the same time represent both a terminological construction and a regional reference which expresses the indecisiveness of the West on social and cultural properties of the Balkans and the founding of Balkan cultures as immanently European, but at the same time the means of measurement, which is not only the determination of regionalism, but the determination of historical and political moment likewise. Besides, Western Balkans could also be interpreted as a mean of practical methodology and classification of naming the societies on the Balkans, which are the only outside the European Union frames, but also stand for the synchronization of the Balkanistic discourse with current political and historical circumstances and

    Objective: To diagnose common organisms causing Chronic Suppurative Otitis Media (CSOM) and their in vitro sensitivity. Methodology: This descriptive study was carried out at Ear Nose and Throat (ENT) Department, Combined Military Hospital (CMH) Multan from July 2014 to June 2015. A total of 140 patients with active CSOM were included in this study. Ear swabs were collected from the discharging ear and sent for aerobic cultures only. Antibiotic sensitivity testing was done with standard antibiotic discs using Kirby Bauer disk diffusion method. Results: Pathogens were isolated in all except 13 ears. Pseudomonas aeruginosa was the most common organism isolated alone in 76 ears and in combination with other micro-organisms in 18 ears, followed by staphylococcus aureus in 23 and MRSA in four ears. Mixed organisms were found in 20 patients. Antibiotic sensitivity of Pseudomonas aeruginosa showed that 100% isolates were sensitive to imipenem and meropenem while Staphylococcus aureus was 100% sensitive to Chloramphenicol. Conclusion: Pseudomonas aeruginosa and staphylococcus aureus were commonest organism isolated in CSOM. Similar studies should periodically be conducted in various regions to have a current knowledge of the offending organisms and their sensitivity patterns against various antibiotics before commencing treatment of CSOM.

  1. Efficacy Coefficients Determined Using Nail Permeability and Antifungal Activity in Keratin-Containing Media Are Useful for Predicting Clinical Efficacies of Topical Drugs for Onychomycosis.

    Directory of Open Access Journals (Sweden)

    Yoshiki Matsuda

    Full Text Available Onychomycosis is difficult to treat topically due to the deep location of the infection under the densely keratinized nail plate. In order to obtain an in vitro index that is relevant to the clinical efficacy of topical anti-onychomycosis drugs, we profiled five topical drugs: amorolfine, ciclopirox, efinaconazole, luliconazole, and terbinafine, for their nail permeabilities, keratin affinities, and anti-dermatophytic activities in the presence of keratin. Efinaconazole and ciclopirox permeated full-thickness human nails more deeply than luliconazole. Amorolfine and terbinafine did not show any detectable permeation. The free-drug concentration of efinaconazole in a 5% human nail keratin suspension was 24.9%, which was significantly higher than those of the other drugs (1.1-3.9%. Additionally, efinaconazole was released from human nail keratin at a greater proportion than the other drugs. The MICs of the five drugs for Trichophyton rubrum were determined at various concentrations of keratin (0-20% in RPMI 1640 medium. The MICs of ciclopirox were not affected by keratin, whereas those of efinaconazole were slightly increased and those of luliconazole and terbinafine were markedly increased in the presence of 20% keratin. Efficacy coefficients were calculated using the nail permeation flux and MIC in media without or with keratin. Efinaconazole showed the highest efficacy coefficient, which was determined using MIC in media with keratin. The order of efficacy coefficients determined using MIC in keratin-containing media rather than keratin-free media was consistent with that of complete cure rates in previously reported clinical trials. The present study revealed that efficacy coefficients determined using MIC in keratin-containing media are useful for predicting the clinical efficacies of topical drugs. In order to be more effective, topical drugs have to possess higher efficacy coefficients.

    Scholarship in public relations seems to be overly positive about social media. The dominant discourse in public relations is that using social media is “good”, because social media can help organizations in developing dialogs and relationships with publics and in engaging with them. Yet empirical...... evidence in public relations is mostly case-dependent and limited to the realm of understanding current organizational practices, with limited understanding of the concrete value for organizations or for publics. In this paper I question the utility of social media for publics, organizations and public...... relations, and I argue that the positive view of social media held by the majority of public relations scholars is grounded on the profession’s need to reconcile the two sides of public relations identity—the rhetorical and the relational.

    Nd 3+ -doped yttrium oxide nanoparticles (Y 2 O 3 :Nd) with cubic phase were obtained successfully by a glycine-nitrate solution combustion method. The results of Fourier transform infrared spectra (FTIR) showed that the -OH groups residing on the nanoparticles surfaces were reduced effectively by modifying with capping agent. The modified Y 2 O 3 :Nd nanoparticles displayed good monodispersity and excellent luminescence in N,N-dimethylformamide (DMF) solvent. Some optical parameters were calculated by Judd-Ofelt analysis based on absorption and fluorescence spectra. A relative large stimulated emission cross section, 1.7 x 10 -20 cm 2 , of the 4 F 3/2 → 4 I 11/2 transition was calculated. Theses results show that the modified Y 2 O 3 :Nd nanoparticles display good luminescence behavior in organic media. (orig.)

    2009-03-01

    Metallothioneins (MTs) are a family of low molecular weight, cysteine-rich and metal-binding functional proteins. Transgenic MT mushroom can be used as functional food additives, but its zinc-enriching ability has not been studied systemically until now. The zinc contents in mycelia of transgenic MT mushroom (Pleurotus ostreatus) and wild type mushroom mycelia cultivated in different zinc concentration media were analyzed by ICP-OES. The growth status, zinc-enriching ability and degree of zinc in organic form (DZOF) were also analyzed. Results showed that MT mushroom mycelia grew rapidly, but the growth was inhibited when the zinc content in solid media was higher than 1.6 mmol x L(-1). MT mushroom mycelia could enrich more zinc than that of wild type, and the zinc content in MT mushroom mycelia could be 2.56-27.49 mg x kg(-1) when it was cultivated in a liquid media with 0.6-1.2 mmol x L(-1) zinc. DZOF of MT mushroom mycelia in a liquid media with 0.6 mmol x L(-1) zinc at 7 d was significantly higher (88.7%) than that in the wild type (82.1%, alpha = 0.05), but there was no significant difference in DZOF when the MT mushroom mycelia was cultivated in a liquid media with different zinc content at 7 d.

    The clear, timely communication of natural hazards information is critical to providing the public with the tools and information they need to make informed decisions before, during, and after events such as earthquakes, tsunamis, and volcanic eruptions. For the geohazards community, this is a multi-sector collaboration involving partners from national, state, and local governments, businesses, educational organizations, non-profit groups, and scientific institutions, for the benefit and participation of the whole community. Communications channels must be clear, consistent, and unified for the sake of maximum reach. One method of public communication that has proven to be particularly effective in disseminating hazards-related information is social media. The broad social and geographic reach of social media coupled with its ubiquitous use in all age groups makes it a powerful way to reach large segments of the population. Social media is already widely used by mass media and scientific organizations to communicate science and hazards. However, it is important that science organizations present a united and clear message, particularly about hazards preparation and response. The Southern California Earthquake Center (SCEC), UNAVCO, and the Incorporated Research Institutions for Seismology (IRIS) have created a Joint Social Media Task Force. The objective of this collaboration is 1) to build social media communities and improve the reach of science messaging, 2) to create and present consistent and clear messaging across social media platforms and regional facilities, 3) to promote outstanding products and educational information , 4) to assist and collaborate in regional, national and international efforts (TweetChats, Reddit fora, ShakeOut, etc.) and 5) to assist and support the efforts of FEMA, the USGS and other partner organizations during crisis situations. Here, we outline the difficulties and successes of creating such an alliance and provide a road map

    In nonaqueous enzymology, control of enzyme hydration is commonly approached by fixing the thermodynamic water activity of the medium. In this work, we present a strategy for evaluating the water activity in molecular dynamics simulations of proteins in water/organic solvent mixtures. The method...... relies on determining the water content of the bulk phase and uses a combination of Kirkwood−Buff theory and free energy calculations to determine corresponding activity coefficients. We apply the method in a molecular dynamics study of Candida antarctica lipase B in pure water and the organic solvents...

    Wramsten Wilmar, Maria; Ahlborg, Gunnar; Jacobsson, Christian; Dellve, Lotta

    2014-01-07

    Over the last decade healthcare management and managers have increasingly been in focus in public debate. The purpose of the present study was to gain a deeper understanding of how prolonged, unfavorable media focus can influence both the individual as a person and his or her managerial practice in the healthcare organization. In-depth interviews (n = 49) with 24 managers and their superiors, or subordinate human resources/information professionals, and partners were analyzed using a grounded theory approach. The conceptual model explains how perceived uncertainties related to the managerial role influence personification and its negative consequences. The role ambiguities comprised challenges regarding the separation of individual identity from the professional function, the interaction with intra-organizational support and political play, and the understanding and acceptance of roles in society. A higher degree of uncertainty in role ambiguity increased both personification and the personal reaction to intense media pressure. Three types of reactions were related to the feeling of being infringed: avoidance and narrow-mindedness; being hard on self, on subordinates, and/or family members; and resignation and dejection. The results are discussed so as to elucidate the importance of support from others within the organization when under media scrutiny. The degree of personification seems to determine the personal consequences as well as the consequences for their managerial practice. Organizational support for managers appearing in the media would probably be beneficial for both the manager and the organization.

    Filtration technology is well established in the water sector but is limited by inability to remove targeted contaminants, found in surface and groundwater, which can be damaging to human health. This study optimises the design of filters by examining the efficacy of seven media (fly ash, bottom ash, Bayer residue, granular blast furnace slag (GBS), pyritic fill, granular activated carbon (GAC) and zeolite), to adsorb nitrate, ammonium, total organic carbon (TOC), aluminium, copper (Cu) and phosphorus. Each medium and contaminant was modelled to a Langmuir, Freundlich or Temkin adsorption isotherm, and the impact of pH and temperature (ranging from 10 °C to 29 °C) on their performance was quantified. As retention time within water filters is important in contaminant removal, kinetic studies were carried out to observe the adsorption behaviour over a 24h period. Fly ash and Bayer residue had good TOC, nutrient and Cu adsorption capacity. Granular blast furnace slag and pyritic fill, previously un-investigated in water treatment, showed adsorption potential for all contaminants. In general, pH or temperature adjustment was not necessary to achieve effective adsorption. Kinetic studies showed that at least 60% of adsorption had occurred after 8h for all media. These media show potential for use in a multifunctional water treatment unit for the targeted treatment of specific contaminants. Copyright © 2015 Elsevier B.V. All rights reserved.

    2018-04-01

    This paper describes a method of detecting organic compounds in water using an ultraviolet LED (280 nm) spectroscopy system and a photodetector. The LED spectroscopy system showed a high correlation between the concentration of the prepared potassium hydrogen phthalate and that calculated by multiple linear regression, indicating an adjusted coefficient of determination ranging from 0.953-0.993. In addition, a comparison between the performance of the spectroscopy system and the total organic carbon analyzer indicated that the difference in concentration was small. Based on the close correlation between the spectroscopy and photodetector absorbance values, organic measurement with a photodetector could be configured for monitoring.

    Social media can support people with communication disability to access information, social participation and support. However, little is known about the experiences of people with traumatic brain injury (TBI) who use social media to determine their needs in relation to social media use. To determine the views and experiences of adults with TBI and cognitive-communication disability on using social media, specifically: (1) the nature of their social media experience; (2) barriers and facilitators to successful use; and (3) strategies that enabled their use of social media. Thirteen adults (seven men, six women) with TBI and cognitive-communication disability were interviewed about their social media experiences, and a content thematic analysis was conducted. Participants used several social media platforms including Facebook, Twitter, Instagram and virtual gaming worlds. All but one participant used social media several times each day and all used social media for social connection. Five major themes emerged from the data: (1) getting started in social media for participation and inclusion; (2) drivers to continued use of social media; (3) manner of using social media; (4) navigating social media; and (5) an evolving sense of social media mastery. In using platforms in a variety of ways, some participants developed an evolving sense of social media mastery. Participants applied caution in using social media, tended to learn through a process of trial and error, and lacked structured supports from family, friends or health professionals. They also reported several challenges that influenced their ability to use social media, but found support from peers in using the social media platforms. This information could be used to inform interventions supporting the use of social media for people with TBI and directions for future research. Social media offers adults with TBI several opportunities to communicate and for some to develop and strengthen social relationships

    In this report, three new metal-organic frameworks (MOFs), [Co 3(μ3-OH)(HBTC)(BTC)2Co(HBTC)]·(HTEA) 3·H2O (NTU-Z30), [Co(BTC)] ·HTEA·H2O (NTU-Z31), [Co3(BTC) 4]·(HTEA)4 (NTU-Z32), where H3BTC = 1,3,5-benzenetricarboxylic acid, TEA = triethylamine, and NTU = Nanyang Technological University, have been successfully synthesized under surfactant media and have been carefully characterized by single-crystal X-ray diffraction, powder X-ray diffraction, thermogravimetric analysis, and IR spectromtry. NTU-Z30 has an unusual trimeric [Co3(μ3-OH)(COO) 7] secondary building unit (SBU), which is different from the well-known trimeric [Co3O(COO)6] SBU. The topology studies indicate that NTU-Z30 and NTU-Z32 possess two new topologies, 3,3,6,7-c net and 2,8-c net, respectively, while NTU-Z31 has a known topology rtl type (3,6-c net). Magnetic analyses show that all three materials have weak antiferromagnetic behavior. Furthermore, NTU-Z30 has been selected as the heterogeneous catalyst for the aerobic epoxidation of alkene, and our results show that this material exhibits excellent catalytic activity as well as good stability. Our success in growing new crystalline cobalt 1,3,5- benzenetricarboxylate MOFs under surfactant media could pave a new road to preparing new diverse crystalline inorganic materials through a surfactant-thermal method. © 2014 American Chemical Society.

    Full Text Available During the past few years, there has been growing interests in reducing cost of products and services among developing countries. Privatization is believed to be one of the most important techniques to increase relative efficiencies of publically held organizations. In this paper, we study important barriers on privatization of television (TV media industry in Iran. The proposed study of this paper designs and distributes a questionnaire using a sample of 234 out of 600 graduate students who were enrolled in media communication studies and examined six hypotheses based on one-side t-student. The survey considers different factors influencing privatization of TV media industry. The results of the investigation indicate that the cost of TV production, short and long-term investment security, people's interest on investing on TV media industry, building appropriate culture, cultural obstacles and economic barriers influence media privatization, significantly.

    Potting media and organic fertilizers (OFs) are commonly used in agricultural systems. However, there is a lack of studies on the efficiency of culture-based techniques in assessing the level of fungal diversity in these products. A study was conducted to investigate the efficiency of seven culture-based techniques and pyrosequencing for characterizing fungal diversity in potting media and OFs. Fungal diversity was evaluated using serial dilution, direct plating and baiting with carrot slices, potato slices, radish seeds, cucumber seeds and cucumber cotyledons. Identity of all the isolates was confirmed on the basis of the internal transcribed spacer region of the ribosomal RNA (ITS rRNA) sequence data. The direct plating technique was found to be superior over other culture-based techniques in the number of fungal species detected. It was also found to be simple and the least time consuming technique. Comparing the efficiency of direct plating with 454 pyrosequencing revealed that pyrosequencing detected 12 and 15 times more fungal species from potting media and OFs respectively. Analysis revealed that there were differences between potting media and OFs in the dominant phyla, classes, orders, families, genera and species detected. Zygomycota (52%) and Chytridiomycota (60%) were the predominant phyla in potting media and OFs respectively. The superiority of pyrosequencing over cultural methods could be related to the ability to detect obligate fungi, slow growing fungi and fungi that exist at low population densities. The evaluated methods in this study, especially direct plating and pyrosequencing, may be used as tools to help detect and reduce movement of unwanted fungi between countries and regions. © 2015 The Society for Applied Microbiology.

    Mask, Lisa; Blanchard, Céline M

    2011-04-01

    Women's responses to 'thin ideal' media pending their level of general self-determination (GSD) were examined. High and low GSD women (N = 99) viewed a 'thin physique salient' (TPS) video or a 'thin physique non-salient' (TPNS) video. Following exposure to the TPS video, perceptions of pressure from the media to be thin, body dissatisfaction, and concerns over quantity of food were greater for low but not high GSD women. However, high GSD women reported greater concerns over the quality of food they eat following exposure to the TPNS video. Prevention efforts aimed at enhancing GSD are discussed.

    Streptomyces rimosus is an oxytetracycline (OTC) antibiotic producing bacteria that exhibited activities against gram positive and negative bacteria. OTC is used widely not only in medicine but also in production industry. The antibiotic production of streptomyces covers a very wide range of condition. However, antibiotic producers are particularly fastidious cultivated by proper selection of media such as carbon source. In present study we have optimised conditions of OTC production (Composition of production media, p H, shaking and temperature). The results have been shown that bran barley is the optimal media for OTC production at 28C pH5.8 at 150rpm for 5 days. For antibiotic determination, OTC was extracted with different organic solvent. Thin-layer chromatography system was used for separation and identification of OTC antibiotic. High performance liquid chromatographic (HPLC) method with ultraviolet detection for the analysis of OTC is applied to the determination of OTC purification. (Author). 24 refs

    Dual media filter (DMF) is being used as a primary pretreatment to remove particulate foulants at seawater desalination plants. However, many plants experience organic and biological fouling. The first part of this paper focuses on the monitoring of organic and biological foulants using advanced analytical techniques to optimize functioning of DMF at Perth Seawater Desalination Plant (PSDP) in Western Australia. In addition, microbial community analysis in DMF filtered seawater, and on DMF media (DMF-M) and cartridge filter (CF) was conducted using terminal restriction fragment length polymorphism (T-RFLP) and 454-pyrosequencing. In the full-scale DMF system, the bacterial community structure was clustered along with the filtration time and sampling positions. For the DMF effluent samples, the bacterial community structure significantly shifted after 4 h of filtration time, which corresponded with the permeability reduction trend. The dominant bacterial communities in the DMF effluent were OTU 13 (Phaeobacter) and OTU 19 (Oceaniserpentilla). The different biofilm-forming bacteria communities were found in the biofilm samples on DMF-M and CF. In the second part of the study, semi-pilot scale DMF columns were operated on-site under same operating conditions used in PSDP. It demonstrated the advantage of operating DMF at the biofiltration mode for improving the reduction of biofoulants. © 2016 Elsevier B.V.

    Chronic otitis media is described as a tympanic membrane perforation and ear discharge for more than six weeks duration. Ascending infection from the nasopharynx into the middle ear cleft has been attributed to prevent resolution of chronic otitis media. This research aims to determine the association between the microbiological flora of the nasopharynx with that of the middle ear in patients suffering from chronic (active) mucosal otitis media. Methods: Our study is a hospital-based cross-sectional survey. It was conducted from December 2015 to February 2017 at the Department of ENT, Combined Military Hospital, Abbottabad. Ear and nasopharyngeal swabs were obtained from 65 patients of chronic active mucosal otitis media and sent for microbiological analysis. Microbiological culture and sensitivity test was performed to identify the microbial spectrum of each specimen. Performa bearing the result of otoscopy, aspirate and swabs were completed for middle ear and the nasopharyngeal culture with reference to each patient. Descriptive statistics and Pearson's chi square analysis were performed using SPSS-22. Results: Staphylococcus aureus and Pseudomonas aeruginosa are foremost micro-organisms found in otorrhea culture isolated from patients of chronic active mucosal otitis media. Majority of the cultures from nasopharynx of these patients did not reveal any growth after incubation for 48 hours. Conclusion: A statistically insignificant association exists between the microbiological spectrum of the middle ear and the nasopharynx of patients suffering from chronic active mucosal otitis media. Micro organisms' exposure from a perforated tympanic membrane remains leading cause of persistent otorrhea, rather than ascending infection through the Eustachian tube. (author)

    2014-01-01

    Weibo media, known as the real-time microblogging services, has attracted massive attention and support from social network users. Weibo platform offers an opportunity for people to access information and changes the way people acquire and disseminate information significantly. Meanwhile, it enables people to respond to the social events in a more convenient way. Much of the information in Weibo media is related to some events. Users who post different contents, and exert different behavior or attitude may lead to different contribution to the specific event. Therefore, classifying the large amount of uncategorized social circles generated in Weibo media automatically from the perspective of events has been a promising task. Under this circumstance, in order to effectively organize and manage the huge amounts of users, thereby further managing their contents, we address the task of user classification in a more granular, event-based approach in this paper. By analyzing real data collected from Sina Weibo, we investigate the Weibo properties and utilize both content information and social network information to classify the numerous users into four primary groups: celebrities, organizations/media accounts, grassroots stars, and ordinary individuals. The experiments results show that our method identifies the user categories accurately.

    This study has successfully identified ion exchanger media suitable for decontaminating the 5500-gallon organic layer in Tank 241-C-103. Decontamination of radionuclides is necessary to meet shipping, incinerator site storage, and incineration feed requirements. The exchanger media were identified through a literature search and experiments at the Russian Institute for Physical Chemistry. The principal radionuclides addressed are Cs-137 and Sr-90. Recommendations for an experimental program plan conclude the discussion. The experimental program would provide the data necessary for plant design specifications for a column and for ion exchange media to be used in decontaminating the organic layer

  3. Multi-criteria media mix decision model for advertising multiple product with segment specific and mass media

    Full Text Available Judicious media planning decisions are crucial for successful advertising of products. Media planners extensively use mathematical models supplemented with market research and expert opinion to devise the media plans. Media planning models discussed in the literature largely focus on single products with limited studies related to the multi-product media planning. In this paper we propose a media planning model to allocate limited advertising budget among multiple products advertised in a segmented market and determine the number of advertisements to be given in different media. The proposed model is formulated considering both segment specific and mass media vehicles to maximize the total advertising reach for each product. The model also incorporates the cross product effect of advertising of one product on the other. The proposed formulation is a multi-objective linear integer programming model and interactive linear integer goal programming is discussed to solve the model. A real life case study is presented to illustrate the application of the proposed model.

  4. From voice to voices: identifying a plurality of Muslim sources in the news media.

    2017-03-01

    This article identifies a qualitative change in the diversity of actors who represent Muslims in British news media. Hitherto, the literature discussing Muslims and the media has tended to characterize media organizations as institutions which portray Muslims in an essentialized, monolithic way. In contrast, I propose in this article that the process of representation is more complex, including greater agency and engaging a wider diversity of Muslims than the prevailing literature suggests. Sociological studies distinguish between official and unofficial sources who help determine the representations that journalists employ in their texts, and I apply this to Muslim communities in Glasgow. Using qualitative methods drawn from media production analysis, including participant-observation and ethnographic interviews, I identify a shift from a 'gatekeeper' model of representing the community to that of a plurality of sources, which reveals and insists on the diversity of Muslim communities and voices. I will show why a wider range of actors emerged to speak publicly, what differentiates them and how they position themselves as representatives of Muslims. This focus on producers and on source strategies brings fresh insights into a field dominated by content analysis and a 'media-centric' approach.

    Tritium atoms can replace hydrogen atoms in organic compounds, forming Organic Bound Tritium. Therefore, exposure of the body to tritium may lead to binding of tritium in tissue molecules, retaining it in the body longer than HTO, and causing higher doses. Ignoring this effect when evaluating inner exposures, may lead to under-estimation of tritium exposures. It was published, that tritium bound to some organic molecules has the potential to accumulate in organisms at higher levels as in the surrounding media. In order to investigate this effect and to identify physiological factors, OBT production in human malignant MG-63 osteoblast cells was studied. The purpose of the present work was to investigate the influence of the ionic extracellular potassium concentration on the amount of tritium in cells. Potassium is known as an ionic compound present in the body, which has the potential to cause cells swelling. Therefore, cells were exposed to isotonic and hypotonic media, supplemented with different concentrations of KCl, and the tritium accumulations were determined after incubation with HTO. An increase in the total Organic Bound Tritium production was observed, as well as an increase of the intracellular HTO content when increasing the KCl concentration. (author)

    1988-08-01

    Ion-exchange media, both bead resins and powdered filter media, are used in nuclear power plants to remove radioactivity from process water prior to reuse or environmental discharge. Since the ion- exchange media are made from synthetic hydrocarbon-based polymers, they may be susceptible to damage from biological activity. The purpose of this study was to investigate some of the more basic aspects of biodegradation of ion-exchange media, specifically to evaluate the ability of microorganisms to utilize the ion-exchange media or materials sorbed on them as a food source. The ASTM-G22 test, alone and combined with the Bartha Pramer respirometric method, failed to indicate the biodegradability of the ion-exchange media. The limitation of these methods was that they used a single test organism. In later phases of this study, a mixed microbial culture was grown from resin waste samples obtained from the BNL High Flux Beam Reactor. These microorganisms were used to evaluate the susceptibility of different types of ion-exchange media to biological attack. Qualitative assessments of biodegradability were based on visual observations of culture growths. Greater susceptibility was associated with increased turbidity in solution indicative of bacterial growth, and more luxuriant fungal mycelial growth in solution or directly on the ion-exchange resin beads. 21 refs., 9 figs., 18 tabs

    Social media has emerged as a popular mode of communication, with more than 73% of the teenage and adult population in the United States using it on a regular basis [Lenhart et al., 2010]. Young people in particular (ages 12-29) are deeply involved in the rapidly evolving social media environment and have an expectation of communication through these media. This engagement creates a valuable opportunity for scientific organizations and programs to use the wide reach, functionality, and informal environment of social media to create brand recognition, establish trust with users, and disseminate scientific information.

    2014-07-01

    The purpose of the study was to identify and understand social media usage behaviour of dentists in South Africa, in general and in particular as part of their marketing strategy and to consider the potential determinants associated with these behaviours. Dentists who are members of the South African Dental Association were requested to anonymously complete an online questionnaire. Apart from demographic information, respondents were asked to report on their use of social media and their adoption of social media marketing. One-on-one interviews were also conducted with three dentists, to gain a deeper understanding of their adoption of this marketing option. South African dentists have started to embrace social media and 50.2% interact through these channels at least once a day. The most popular social media platforms are GooglePlus and Facebook. Respondents use social media mainly for personal purposes, including staying connected to family and friends.. Only 13.2% of those responding currently use social media as a marketing tool, but the majority (83.5%) predict that such usage will increase in future. Social media marketing is a growing trend and will become more significant in future. Although respondents used social media regularly for personal purposes, most are only now starting to use it as a marketing tool.

    Organically produced spices and herbs were analyzed for determination of aflatoxin B1 (AFB1) by ELISA using immunoaffinity column. For this purpose 93 organic spices and 37 organic herbs were randomly selected from organic markets and organic shops in Turkey. AFB1 was detected in 58 organic spice and 32 organic herb samples. Among organic spice samples, the maximum value was detected in cinnamon sample (53 μg/kg). AFB1 was not detected in thyme samples. AFB1 levels of 41 organic spice samples were above the EU regulatory limit (5 μg/kg). Among organic herb samples the highest concentration of AFB1 (52.5 μg/kg) was detected in a rosehip sample. AFB1 levels of 21 organic herb samples were above the regulatory limits of the European Union. These results showed that more stringent measures must be taken for the prevention of mold contamination in the production of organic spices and herbs. PMID:23766719

    An improved method for the simultaneous determination of 20 amino acids and 7 carbohydrates using one-valve switching after injection, ion chromatography, and integrated pulsed amperometric detection is proposed. The resolution of the amino acids and carbohydrates in the cation trap column was investigated. In addition, parameters including flow liquid type, flow rate, concentration, and valve-switch timing were optimized. The method is time-saving, effective, and accurate for the simultaneous separation of amino acids and carbohydrates, with a mean correlation coefficient of >0.99 and repeatability of 0.5-4.6% for eight replicates. The method was successfully applied in the analysis of amino acids and carbohydrates in aseptic media and in extracellular culture media of three phenotypes of Clostridium thermocellum.

    Schiff bases are an important class of ligands in coordination chemistry and find extensive application in different fields. Recently, increased interest in organic thin film materials has arisen due to their extensive applications in the fields of mechanics, flexible electronics and optics. Optoelectronics is the area in which organic films and organic-inorganic nanostructures have found their main applications in the last decade. These organic thin films have been also used in a wide variety of applications such as Schottky diodes, solid state devices and optical sensors. The optical constants (refractive index, n; extinction coefficient, k and dielectric constant, e) of some organic thin films were determined using reflectance and transmittance spectra. Analysis of the basis absorption spectra was also carried out to determine optical band gap (Eg) and Urbach parameter (E0). A surface observation of these thin films was also carried out by an Atomic Force Microscope.

  19. Social media as marketing tool for SMEs: opportunities and challenges

    Full Text Available Social media is a phenomenon that has transformed the interaction and communication of individuals throughout the world. Especially, social networking websites are very popular and have become daily practice in a lot of people’s lives. These sites have made significant impact on the individual’s life. However, social media is not only a communication tool for amusement, but it is also an important part of marketing strategies in business life. There is a constant rise in social networking and therefore impact of social networks is becoming stronger every day, into each kind of business. Social media are often used as a source of information and spread of knowledge changing people’s views and opinions. They belong among very important business marketing tactics and help to create new business opportunities, develop a stronger market position or modify consumer’s behaviour. Therefore, in developed countries, social media are gaining popularity and are increasingly used in regular operations of many companies, including start-ups, small, medium-sized, and large organizations. But it seems that in emerging economies such as Kosovo, Albania and other neighbour countries, marketing over social media is not taken that seriously, especially by SMEs. There are some companies who have shown interest and have created their presence, yet there is no serious focus in this innovative marketing tool. The study deals with the issue of social media and its influence on SMEs. It classifies social media and explores the possibilities and challenges of social networks in business. The authors describe features and the evolution of social media, including major social networking sites that came into existence during the 21st century. The purpose of the paper is to review the academic literature on the opportunities and challenges of using social media from SMEs, as well as identifying factors that drive social media marketing adoption and usage in SMEs.

  20. Humanitarian crises: what determines the level of emergency assistance? Media coverage, donor interests and the aid business.

    Science.gov (United States)

    Olsen, Gorm Rye; Carstensen, Nils; Høyen, Kristian

    2003-06-01

    This paper proposes a basic hypothesis that the volume of emergency assistance any humanitarian crisis attracts is determined by three main factors working either in conjunction or individually. First, it depends on the intensity of media coverage. Second, it depends on the degree of political interest, particularly related to security, that donor governments have in a particular region. Third, the volume of emergency aid depends on strength of humanitarian NGOs and international organisations present in a specific country experiencing a humanitarian emergency. The empirical analysis of a number of emergency situations is carried out based on material that has never been published before. The paper concludes that only occasionally do the media play a decisive role in influencing donors. Rather, the security interests of Western donors are important together with the presence and strength of humanitarian stakeholders, such as NGOs and international organisations lobbying donor governments.

    A discussion on how nurse leaders are using social media and developing digital leadership in online communities. Social media is relatively new and how it is used by nurse leaders and nurses in a digital space is under explored. Discussion paper. Searches used CINAHL, the Royal College of Nursing webpages, Wordpress (for blogs) and Twitter from 2000-2015. Search terms used were Nursing leadership + Nursing social media. Understanding the development and value of nursing leadership in social media is important for nurses in formal and informal (online) leadership positions. Nurses in formal leadership roles in organizations such as the National Health Service are beginning to leverage social media. Social media has the potential to become a tool for modern nurse leadership, as it is a space where can you listen on a micro level to each individual. In addition to listening, leadership can be achieved on a much larger scale through the use of social media monitoring tools and exploration of data and crowd sourcing. Through the use of data and social media listening tools nursing leaders can seek understanding and insight into a variety of issues. Social media also places nurse leaders in a visible and accessible position as role models. Social media and formal nursing leadership do not have to be against each other, but they can work in harmony as both formal and online leadership possess skills that are transferable. If used wisely social media has the potential to become a tool for modern nurse leadership. © 2016 John Wiley & Sons Ltd.

  2. Determination of the transport levels in thin films of organic semiconductors

    2009-07-27

    The approach of using the combination of Ultraviolet (UPS) and Inverse Photoemission (IPS) to determine the transport levels in thin films of organic semiconductors is the scope of this work. For this matter all influences on the peak position and width in Photoelectron Spectroscopy are discussed with a special focus on organic semiconductors. Many of these influences are shown with experimental results of the investigation of diindenoperylene on Ag(111). These findings are applied to inorganic semiconductors silicon in order to establish the use of UPS and IPS on a well-understood system. Finally, the method is used to determine the transport level of several organic semiconductors (PTCDA, Alq3, CuPc, DIP, PBI-H4) and the corresponding exciton binding energies are calculated by comparison to optical absorption data.

    This work was made with the purpose to complete information about the hydrolysis constants of Europium (III) in high ion strength media. So it was determined at a ion forces media 4, 5 and 6 M of sodium perchlorate at 303 K. The method used was the potentiometric with the aid of the Super quad computer program. In high ion strength media, the measurements of p H do not correspond directly to negative logarithm of the concentration of hydrogen ions, by this it is necessary to calibrate the electrode in these conditions. The Europium was hydrolized at pC H values greater 6 in all cases. The potentiometric method used under the described experimental conditions is adequate to determine the hydrolysis constants of Europium (III). According to the results and diagrams of chemical species of Europium obtained we can conclude that the hydrolysis constants, differ by its distribution but not in its identity. (Author)

  6. The Role of Multimedia Content in Determining the Virality of Social Media Information

    Directory of Open Access Journals (Sweden)

    Paolo Giacomazzi

    2012-07-01

    Full Text Available The paper provides empirical evidence supporting the assumption that content plays a critical role in determining the virality, i.e., the influence, of social media information. The analysis focuses on multimedia content on Twitter and explores the idea that links to multimedia information increase the virality of posts. In particular, we put forward the following three main hypotheses: (1 posts with a link to multimedia content (photo or video are more retweeted than posts without a link; (2 posts linking a photo are more retweeted than posts linking a video, and (3 posts linking a video raise more sentiment than posts linking a photo. Hypotheses are tested on a sample of roughly two million tweets posted in July 2011 including comments on Berlin, London, Madrid, and Milan relevant from a tourism perspective. Findings support our hypotheses and indicate that multimedia content plays an important role in determining not only the volumes of retweeting, but also the dynamics of the virality of posts measured as speed of retweeting.

    Velavendan, P.; Pandey, N.K.; Kamachi Mudali, U.; Natarajan, R.

    2011-01-01

    In the present work a method for the determination of Di-n-butyl phosphate in organic streams using Ion Chromatography technique is developed and described here. The method involves the separation of Di-n-butyl phosphate (DBP) from 30% TBP-NPH (Tri-n-butylphosphate diluted in Normal Paraffin Hydrocarbon) and uranium/nitric acid matrix by an extraction of DBP in alkaline medium and subsequent ion-exchange separation in ion chromatography column followed by suppressed conductivity detection. Direct determination of DBP in lean/loaded organic solvent will lead to in accurate determination of DBP due to organic interference. DBP is quantified to lower limit of 1 ppm with 3% RSD. The results obtained with ion chromatographic technique are compared with those obtained by standard gas chromatographic technique. The developed method is much faster and total analysis can be completed within two hours. (author)

    To analyze specific patterns of Twitter usage using common references to hearing loss, and characterize the virtual public that comprises the hearing loss community to inform hearing loss stakeholders for opportunities for engagement and outreach. Social media network analysis. Twitter tweets were sampled from July 2016 to September 2016 using #hearing, #hearingloss, #deaf, #hearingimpairment, #hardofhearing, #deafness, #hearingmatters, #hearinghealth, and #hearingimpaired tags. User and Twitter social community metrics were examined including temporal trends, tweet content, user activity, tweet reach, and an analysis of the tweets' social network. We identified and analyzed 49,208 tweets from July 2016 to September 2016 with tags relevant to hearing loss. Of the 100 most active Twitter accounts, organizations owned 67% compared to 33% owned by individuals. Commercial/for profit and informational organizations were the most common organization account owners (26% and 16%, respectively). Five unique tweets were identified as each having a reach of over 100,000 Twitter users, with the greatest reach exceeding 250,000 users. Temporal analysis identified marked retweet outliers (>300 retweets per hour) that corresponded with a widely publicized event involving the dismissal of a deaf employee from a fast-food chain store. Twitter accounts owned by organizations outnumbered individual accounts, and commercial/for profit user accounts were the most frequently active organization account type. Tweets pertaining to hearing loss may have a broad reach to a large community base. Analyses of social media use can be helpful in discovering issues of interest to the hearing loss community, as well as determining which users and organizations are dominating social network conversations.

    Vervaart, Peter

    2012-07-01

    Since the advent of the Internet, and in particular the development of the interactive version of the web, Web 2.0, use of Social Media has developed into a major strategy for businesses and organizations such as the IFCC to use for the purposes of Public Relations and Education. The early Internet 'Web 1.0' was a largely static environment which did not allow interaction between organizations and their customers and/or members and as such was mainly used as an information repository rather than a dynamic environment for the exchange of ideas and active marketing and education. Since the development of Web 2.0 we have seen a massive increase in web based traffic which could be loosely called 'social networking' which initially was mainly networking between individuals but more recently has developed into a major marketing resource allowing networking between organizations and individuals on the web. It follows then that by developing a Social Media presence on platforms such as Facebook, LinkedIn, Twitter and other social media sites organizations can use this networking for the purposes of marketing, public relations, and in the case of IFCC, education of members and other interested individuals across the globe.

    2013-09-01

    This article focuses on social media and interactive challenges for emergency organizations during a bioterrorism or agroterrorism incident, and it outlines the dual-use dilemma of social media. Attackers or terrorists can use social media as their modus operandi, and defenders, including emergency organizations in law enforcement and public and animal health, can use it for peaceful purposes. To get a better understanding of the uses of social media in these situations, a workshop was arranged in Stockholm, Sweden, to raise awareness about social media and animal bioterrorism threats. Fifty-six experts and crisis communicators from international and national organizations participated. As a result of the workshop, it was concluded that emergency organizations can collect valuable information and monitor social media before, during, and after an outbreak. In order to make use of interactive communication to obtain collective intelligence from the public, emergency organizations must adapt to social networking technologies, requiring multidisciplinary knowledge in the fields of information, communication, IT, and biopreparedness. Social network messaging during a disease outbreak can be visualized in stream graphs and networks showing clusters of Twitter and Facebook users. The visualization of social media can be an important preparedness tool in the response to bioterrorism and agroterrorism.

    It's tempting to jump on the social media bandwagon and insist your organization needs Facebook, twitter, etc. But, when funds are limited, social media and related publicity must be carefully thought out. The NASA Night Sky Network, which is managed by the Astronomical Society of the Pacific, has developed widgets for websites and blogs, an iPhone app, and a Facebook presence. This is all to attract, inform, and reach the next generation of amateur astronomers, with no additional work needed from the amateur astronomy community who are members of the Night Sky Network. Outreach professionals will gain valuable insight from our experience, and may replicate this model to design their own social media and technology plan.

    The purposes of the current study were to assess the feasibility of post-auricular microinjection of lentiviruses carrying enhanced green fluorescent protein (EGFP) into the scala media through cochleostomies in rats, determine the expression of viral gene in the cochlea, and record the post-operative changes in the number and auditory function of cochlear hair cells (HCs). Healthy rats were randomly divided into two groups. The left ears of the animals in group I were injected with lentivirus carrying EGFP (n=10) via scala media lateral wall cochleostomies, and the left ears of the animals in group II were similarly injected with artificial endolymph (n=10). Prior to and 30 days post-injection, auditory function was assessed with click-auditory brainstem response (ABR) testing, EGFP expression was determined with cochlear frozen sections under fluorescence microscopy, and survival of HCs was estimated based on whole mount preparations. Thirty days after surgery, click-ABR testing revealed that there were significant differences in the auditory function, EGFP expression, and survival of HCs in the left ears before and after surgery in the same rats from each group. In group I, EGFP was noted in the strial marginal cells of the scala media, the organ of Corti, spiral nerves, and spiral ganglion cells. Lentiviruses were successfully introduced into the scala media through cochleostomies in rats, and the EGFP reporter gene was efficiently expressed in the organ of Corti, spiral nerves, and spiral ganglion cells.

    Full Text Available The analysis of the international legal framework for media in a real structural form is a challenge that needs to be scientifically proven because of the exceptional role of media in general and its constant and substantial impact on the democratic processes taking place in the world. If we analyze media through the eyes of history, we cannot ignore the impression of the exceptional importance of freedom of expression as the source and promoter of many substantive changes and valuable components in the overall functioning of social and political settings. In this regard, special attention is given to the impact of media on contemporary trends related to the EU integration process, the development of democracy and the rule of law. It particularly emphasizes the freedom of expression, respect for values and standards principles, human rights and freedoms. The purpose of this paper is to analyze the international legal framework for the media and to show the determination of the most important covenants which represent a source of media law containing rules for the creation and implementation of media freedom, the expressive quality of ideas and definitely and inevitably this paper stresses the power of the media.

  17. Municipal Communication Strategies and Ethnic Media: A Settlement Service in Disguise

    Directory of Open Access Journals (Sweden)

    April Lindgren

    2015-12-01

    Full Text Available The Canadian Federation of Municipalities has declared cities as the “unofficial welcome wagon” for new Canadians. Research suggests, however, that they embrace settlement and integration policies to varying degrees. While scholarly examinations of municipal policies include analyses of corporate communications strategies, efforts by city governments to reach residents through ethnocultural news media have received little attention. To address that gap, this study investigates why the suburban community of Brampton, Canada adopted one of the most proactive ethnic media strategies in the country in 2015 when, just a decade earlier, it was for the most part unresponsive to the needs of its burgeoning immigrant population. As a starting point, the case study uses the determinants of municipal responsiveness identified by Kristin R. Good (2009 in Municipalities and Multiculturalism: The Politics of Immigration in Toronto and Vancouver. Employing a mixed methods approach, it concludes that rapid demographic change, the emergence of an activist political leadership, and efforts to reduce friction between newcomers and other residents influenced Brampton’s communications policy over time. The case study identifies challenges associated with adopting an ethnic media strategy, including issues related to translation and the relative lack of sophistication of some ethnic media outlets. Furthermore, it demonstrates that reaching out to ethnocultural communities via ethnic media requires more than just distributing news releases in English. Translation of these releases has the potential to increase municipal news coverage in ethnic media, the paper suggests, if only because it makes it easier for smaller news organizations to report on such matters.

    2016-01-01

    Over the last few years, the global market of organic vegetables has grown. This is due to increased consumer concern regarding environmental and health issues, especially for food products. This study aims to examine factors that influence consumer behavior in purchasing organic vegetables. In this study, data were obtained from household surveys conducted in the Jabodetabek region (Greater Jakarta) from February to March 2015. Descriptive analysis, factor analysis, and a binary logit model were used to analyze the data. Subsequently, the results show that consumers with fewer family members and have a higher income, and are price tolerant, are more likely to purchase organic vegetables. Meanwhile, female consumers are less likely to buy organic vegetables. Another important finding is that positive attitude towards organic products, safety and health, environmental concerns, as well as degree of trust in organic attributes, are the determinants of organic vegetable purchasing among consumers. Therefore, based on the study results, the following recommendations are needed for organic vegetable development in Indonesia: (a) implementing an appropriate pricing strategy; (b) encouraging organic labeling and certification for vegetables; and (c) intensively promoting organic food with respect to consumers’ motives and concerns on health, safety, as well as environmental sustainability.

  1. Time trends in organ donation after neurologic determination of death: a cohort study

    Science.gov (United States)

    Kramer, Andreas H.; Baht, Ryan; Doig, Christopher J.

    2017-01-01

    Background: The cause of brain injury may influence the number of organs that can be procured and transplanted with donation following neurologic determination of death. We investigated whether the distribution of causes responsible for neurologic death has changed over time and, if so, whether this has had an impact on organ quality, transplantation rates and recipient outcomes. Methods: We performed a cohort study involving consecutive brain-dead organ donors in southern Alberta between 2003 and 2014. For each donor, we determined last available measures of organ injury and number of organs transplanted, and compared these variables for various causes of neurologic death. We compared trends to national Canadian data for 2000-2013 (2000-2011 for Quebec). Results: There were 226 brain-dead organ donors over the study period, of whom 100 (44.2%) had anoxic brain injury, 63 (27.9%) had stroke, and 51 (22.6%) had traumatic brain injury. The relative proportion of donors with traumatic brain injury decreased over time (> 30% in 2003-2005 v. 6%-23% in 2012-2014) (p = 0.004), whereas that with anoxic brain injury increased (14%-37% v. 46%-80%, respectively) (p organs transplanted per donor was 3.6 with anoxic brain injury versus 4.5 with traumatic brain injury or stroke (p = 0.002). Interpretation: Anoxic brain injury has become a leading cause of organ donation after neurologic determination of death in Canada. Organs from donors with anoxic brain injury have a greater degree of injury, and fewer are transplanted. These findings have implications for availability of organs for transplantation in patients with end-stage organ failure. PMID:28401114

    A sensitive, multi-residue method using solid-phase extraction followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed to determine a representative group of 35 analytes, including corrosion inhibitors, pesticides and pharmaceuticals such as analgesic and anti-inflammatory drugs, five iodinated contrast media, β-blockers and some of their metabolites and transformation products in water samples. Few other methods are capable of determining such a broad range of contrast media together with other analytes. We studied the parameters affecting the extraction of the target analytes, including sorbent selection and extraction conditions, their chromatographic separation (mobile phase composition and column) and detection conditions using two ionisation sources: electrospray ionisation (ESI) and atmospheric pressure chemical ionisation (APCI). In order to correct matrix effects, a total of 20 surrogate/internal standards were used. ESI was found to have better sensitivity than APCI. Recoveries ranging from 79 to 134 % for tap water and 66 to 144 % for surface water were obtained. Intra-day precision, calculated as relative standard deviation, was below 34 % for tap water and below 21 % for surface water, groundwater and effluent wastewater. Method quantification limits (MQL) were in the low ng L(-1) range, except for the contrast agents iomeprol, amidotrizoic acid and iohexol (22, 25.5 and 17.9 ng L(-1), respectively). Finally, the method was applied to the analysis of 56 real water samples as part of the validation procedure. All of the compounds were detected in at least some of the water samples analysed. Graphical Abstract Multi-residue method for the determination of micropollutants including pharmaceuticals, iodinated contrast media and pesticides in waters by LC-MS/MS.

  3. Mass transfer of nonvolatile organic compounds from porous media

    Science.gov (United States)

    Khachikian, Crist Simon

    This thesis presents data pertaining to the mass transfer of nonvolatile organic compounds from porous media. Physical properties of porous solids, including surface and pore areas, are studied. Information from these studies, along with dissolution data, are used to develop correlations relating the Sherwood Number to the Peclet Number. The contaminant used in this study is naphthalene; the solids used are Moffett Sand (MS), Borden Sand (BS), Lampblack (LB), and Silica Gel (SG). Surface area results indicate that contamination at 0.1% reduces the area of MS and SG by 48 and 37%, respectively, while contamination at 1.0% reduces the area of MS, BS, and SG by 59, 56, and 40%, respectively. Most of the reduction in area originates in the reduction of pore areas and volumes, where the contaminant precipitates. After long-term storage, surface areas did not recover to their original values due to an "irreversible" fraction of naphthalene. Treatment with heat or solvent or both was necessary to completely remove the contamination. For lampblack, treatment at 100°C decreased areas while treatment at 250°C increased them. Treatment at 250°°C probably opened pores while that at 100°C may have blocked more pores by redistributing the tar-like contaminant characteristic of lampblack. Contaminated MS and SG solids are packed in columns through which water is pumped. The effluent began at a relatively high concentration (˜70% of solubility) for both samples. However, SG column concentrations dropped quickly, never achieving steady state while the MS samples declined more gradually towards steady state. The high pore areas of the SG samples are believed to cause this behavior. The steady state portion of the MS dissolution history is used to develop mass transfer correlations. The correlation in this study differs from previous work in two major ways: (1) the exponent on the Pe is three times larger and (2) the limiting Sh is 106 times smaller. These results suggest that

    Given the demand for authentic personal interactions over social media, it is unclear how much firms should actively manage their social media presence. We study this question empirically in a health care setting. We show that active social media management drives more user-generated content. However, we find that this is due to an incremental increase in user postings from an organization's employees rather than from its clients. This result holds when we explore exogenous variation in socia...

    Social media, a resource largely untapped in the healthcare field, presents opportunities and advantages and, if used properly, can innovate healthcare and create a competitive advantage for adopters. Many organizations have considered social media but dismissed its advantages as fleeting products of the new generation entering the workforce: the millennials. However, the millennial generation has assumed a greater presence in clinical and administrative positions as the baby boomer generation prepares for retirement. This article advocates the adoption of social media in healthcare organizations as a strategic advantage in connecting with their patient population and recruiting and retaining millennial staff amid the generational shift of the healthcare workforce.

    2012-05-01

    Full Text Available Along with the evolution of the Internet and with its growing capacity to impose itself on the population, the consumer has become stronger through the simplification of access to information. Thus, 24 hours out of 24 hours, Internet users from all around the world are searching for relevant information about the product they desire. This is also the reason why organizations are striving to be as present as ever in the online medium, interacting with their consumers, monitoring the information dissipated by them on the Internet about their products, and measuring the effects they have produced. The media available to an organization is represented by: paid media, owned media and earned media. The problem that is raised is that of a correct management by the marketers so that the investment in one type of media will also pursue the conversion in another type of media, thus resulting, through the help of consumers, a chain. When a consumer wants to buy a product, he needs relevant information in order to make a decision. The information about the product is analyzed based on source credibility, which is seen as a perception of the degree of the consumer’s trust. The present study tries to investigate the level of trust the young Romanian consumer has in paid media and earned media during the buying process. The study is conducted on a group of young Romanian people, with ages ranging from 18 to 24 years, from urban backgrounds. In order to observe if there exists a difference in the perception of media based on the type of medium the subject finds himself in, the survey has been conducted online, as well as offline.

    2014-01-01

    Full Text Available Weibo media, known as the real-time microblogging services, has attracted massive attention and support from social network users. Weibo platform offers an opportunity for people to access information and changes the way people acquire and disseminate information significantly. Meanwhile, it enables people to respond to the social events in a more convenient way. Much of the information in Weibo media is related to some events. Users who post different contents, and exert different behavior or attitude may lead to different contribution to the specific event. Therefore, classifying the large amount of uncategorized social circles generated in Weibo media automatically from the perspective of events has been a promising task. Under this circumstance, in order to effectively organize and manage the huge amounts of users, thereby further managing their contents, we address the task of user classification in a more granular, event-based approach in this paper. By analyzing real data collected from Sina Weibo, we investigate the Weibo properties and utilize both content information and social network information to classify the numerous users into four primary groups: celebrities, organizations/media accounts, grassroots stars, and ordinary individuals. The experiments results show that our method identifies the user categories accurately.

  17. Mass Media and Cultural Memory: Idealization of Values

    Directory of Open Access Journals (Sweden)

    Liljana Siljanovska

    2014-12-01

    Full Text Available The theoretical approach in defining the means for mass communication expressed in functionalist theory, especially in John Riley’s model, determines mass media as a social subsystem which is functionally connected with other systems in society that arises from their mutual conditionality and their causative and consequential connection with politics, economy, education, socialization and culture. The functions of articulating opinion by themselves problematize the creation of creative-thinking public because the imposition of topics, representation of individuals, values and norms of a culture, a space, a time is mediated by the ideological and functional mechanism of an organized structuring and transfer of messages simultaneously to as big an audience as possible. The vastness of the audience simply cannot by itself be understood as democratization of the culture in its broadest sense or simply because it is not a high, elite culture intended solely for a certain number of users.  It is that exact media reality, which almost always and exclusively is created through the selection of facts and values in relation to the audience and the factor of time, which simultaneously problematizes individual and collective memory. In the era of postmodernism and globalization of societies, media shaped content, in different mass media, especially on TV and the Internet, stimulate cultural development and pluralism of ideas in intercultural communication. However at the same time the setting of the stage for a media product, imposed by market logic of supply and demand erases the borders of difference, restructures the modalities of cultural identifiers and relativizes the dimensions of cultural identity through the unification of values transformed in surpassed or modern collective memories and concepts, such as – Balkanization, Americanization, Europeanization, civil society.

    Background The use of social media by health care organizations is growing and provides Web-based tools to connect patients, caregivers, and providers. Objective The aim was to determine the use and factors predicting the use of social media for health care–related purposes among medically underserved primary care patients. Methods A cross-sectional survey was administered to 444 patients of a federally qualified community health center. Results Community health center patients preferred that their providers use email, cell phones for texting, and Facebook and cell phone apps for sharing health information. Significantly more Hispanic than white patients believed their providers should use Facebook (P=.001), YouTube (P=.01), and Twitter (P=.04) for sharing health information. Use and intentions to use social media for health-related purposes were significantly higher for those patients with higher subjective norm scores. Conclusions Understanding use and factors predicting use can increase adoption and utilization of social media for health care–related purposes among underserved patients in community health centers.

    A prior randomized controlled trial of social media exposure at Circulation determined that social media did not increase 30-day page views. Whether insufficient social media intensity contributed to these results is uncertain. Original article manuscripts were randomized to social media exposure compared with no social media exposure (control) at Circulation beginning in January 2015. Social media exposure consisted of Facebook and Twitter posts on the journal's accounts. To increase social media intensity, a larger base of followers was built using advertising and organic growth, and posts were presented in triplicate and boosted on Facebook and retweeted on Twitter. The primary outcome was 30-day page views. Stopping rules were established at the point that 50% of the manuscripts were randomized and had 30-day follow-up to compare groups on 30-day page views. The trial was stopped for futility on September 26, 2015. Overall, 74 manuscripts were randomized to receive social media exposure, and 78 manuscripts were randomized to the control arm. The intervention and control arms were similar based on article type (P=0.85), geographic location of the corresponding author (P=0.33), and whether the manuscript had an editorial (P=0.80). Median number of 30-day page views was 499.5 in the social media arm and 450.5 in the control arm; there was no evidence of a treatment effect (P=0.38). There were no statistically significant interactions of treatment by manuscript type (P=0.86), by corresponding author (P=0.35), by trimester of publication date (P=0.34), or by editorial status (P=0.79). A more intensive social media strategy did not result in increased 30-day page views of original research. © 2016 The Authors.

    Full Text Available The paper deals with the system of services that social media management can offer to a variety of users. As social media systems are emerging, social media management can strengthen teams in social media and help to manage numerous social channels and distribution of social information from one place. Social media management is a system of procedures that are used to manage the flow of information in the environment of social media. This involves connecting with social media like Facebook, Twitter, LinkedIn, Plaxo, Ecademy, YouTube and many others, then the aggregation and management of social data. Social media management services are analysed through various fields, such as managing multiple social media profiles, mail scheduling and filtering, reporting and analytics. Social media management enables managing personal business through social media, which contributes to a significant reduction in expenditures. The paper also discusses the importance of social media management in marketing activities and various forms of social promotion, which allow companies to easily reach their customers.

    One aspect of environmental degradation in coastal areas is pollution from toxic metals, which are persistent and are bioaccumulated by marine organisms, with serious public health implications. A conventional monitoring system of environmental metal pollution includes measuring the level of selected metals in the whole organism or in respective organs. However, measuring only the metal content in particular organs does not give information about its effect at the subcellular level. Therefore, the evaluation of biochemical biomarker metallothionein may be useful in assessing metal exposure and the prediction of potential detrimental effects induced by metal contamination. There are some methods for the determination of metallothioneins including spectrophotometric method, electrochemical methods, chromatography, saturation-based methods, immunological methods, electrophoresis, and RT-PCR. In this paper, different methods are discussed briefly and the comparison between them will be presented.

    1983-12-01

    To learn more about the use of the mass media for agricultural extension, the World Bank has considered the efforts of 2 units: INADES-formation in West Africa and the Extension Aids Branch of Malawi. The INADES-formation study focuses on Cameroon but also considers work in Rwanda and the Ivory Coast. Some general conclusions emerge from a comparison of the 2 organizations. Malawi operates an extension service which reaches farmers through extension agents, through farmer training centers, and through mass media. The Extension Aids Branch (EAB) has responsibility for its media work and broadcasts 4 1/2 hours of radio each week. Its 6 regular radio programs include a general program which interviews farmers, a music request program in which the music is interspersed with farming advice, a farming family serial, and a daily broadcast of agricultural news and information. The 17 cinema vans show some agricultural films, made by EAB, some entertainment films, and some government information films from departments other than the ministry of agriculture. EAB also has a well-developed program of research and evaluation of its own work. INADES-formation, the training section of INADES, works towards social and economic development of the population. It teaches peasant farmers and extension agents and does this through running face-to-face seminars, by publishing a magazine, "Agripromo," and through correspondence courses. In 1978-79 INADES-formation enrolled some 4500 farmers and extension agents as students. Both of these organizations work to teach farmers better agriculture techniques, and both were created in response to the fact that agricultural extension agents cannot meet all the farmers in their area. Despite the similarity of objective, there are differences in methods and philosophy. The EAB works in a single country and uses a variety of mass media, with print playing a minor role. INADES-formation is an international and nongovernmental organization and its

    Raman spectroscopy has a broad range of applications across numerous scientific fields, including microbiology. Our work here monitors the influence of culture media on the Raman spectra of clinically important microorganisms (Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis and Candida albicans). Choosing an adequate medium may enhance the reproducibility of the method as well as simplifying the data processing and the evaluation. We tested four different media per organism depending on the nutritional requirements and clinical usage directly on a Petri dish. Some of the media have a significant influence on the microbial fingerprint (Roosvelt-Park Institute Medium, CHROMagar) and should not be used for the acquisition of Raman spectra. It was found that the most suitable medium for microbiological experiments regarding these organisms was Mueller-Hinton agar.

    When introducing innovations to health care, it is important to gain insight into determinants that may facilitate or impede the introduction, in order to design an appropriate strategy for introducing the innovation. To obtain an overview of determinants of innovations in health care organizations, we carried out a literature review and a Delphi study. The Delphi study was intended to achieve consensus among a group of implementation experts on determinants identified from the literature review. We searched 11 databases for articles published between 1990 and 2000. The keywords varied according to the specific database. We also searched for free text. Forty-four implementation experts (implementation researchers, programme managers, and implementation consultants/advisors) participated in the Delphi study. The following studies were selected: (i) studies describing innovation processes, and determinants thereof, in health care organizations; (ii) studies where the aim of the innovations was to change the behaviour of health professionals; (iii) studies where the health care organizations provided direct patient care; and (iv) studies where only empirical studies were included. Two researchers independently selected the abstracts and analysed the articles. The determinants were divided into four categories: characteristics of the environment, characteristics of the organization, characteristics of the user (health professional), and characteristics of the innovation. When analysing the determinants, a distinction was made between systematically designed and non-systematically designed studies. In a systematic study, a determinant analysis was performed and the innovation strategy was adapted to these determinants. Furthermore, the determinants were associated with the degree of implementation, and both users and non-users of the innovation were asked about possible determinants. In the Delphi study, consensus was defined as agreement among 75% of the experts on

    To discuss opportunities and challenges for pharmacists' use of social media to affect health care. Not applicable. Evolutions in social media (e.g., Facebook, Twitter, YouTube) are beginning to alter the way society communicates. These new applications promote openness, user-generated content, social networking, and collaboration. The technologies, along with patient behaviors and desires, are stimulating a move toward more open and transparent access to health information. Although social media applications can reach large audiences, they offer message-tailoring capabilities that can effectively target specific populations. Another powerful aspect of social media is that they facilitate the organization of people and distribution of content-two necessary components of public health services. Although implementing health interventions via social media poses challenges, several examples exist that display the potential for pharmacists to use social media in health initiatives. Pharmacists have long played a role in educating patients on matters influencing health care. Social media offer several unique features that may be used to advance the role of pharmacy in health care initiatives. Public familiarity with social media, the economical nature of using social media, and the ability to disseminate information rapidly through social media make these new applications ideal for pharmacists wanting to provide innovative health care on both an individual and public level.

    A theoretical and experimental study of the plasma volume expansion consequent on the hyperosmolality of contrast media is presented. In the case of the ratio 1.5 media theory and experiment coincide closely but in the case of the ratio 3 media the observed changes exceed the predicted. It is proposed that this is due partly to the slower diffusion of the ratio 3 media out of the intravascular space and partly due to the fact that the osmotic load presented by these media is greater than would be expected from a study of their commercial solutions in which osmolality is reduced by molecular aggregation. The implications for the relative haemodynamic effects of different contrast media are discussed. The osmotic effects of contrast media also play a part in determining the image quality achievable in intravenous digital subtraction angiography (IV-DSA). It is predicted that ratio 3 contrast media will give better quality images in IV-DSA than ratio 1.5 media. (orig.)

    Families and children are in the midst of a media revolution. Television, Internet access, instant messaging, cell phones, and interactive video games are delivering more information for more hours than ever in history. Exposure is occurring at younger and younger ages, often without parental oversight or interpretation. The impact on children is just beginning to be studied. Does media exposure prepare children for the world in which they live or deprive them of critical developmental opportunities? Does the steady display of violence contribute to violent behavior? This article presents a developmental context, discusses the research conducted to date, reviews the recommendations of major organizations, and tries to take a balanced perspective in the midst of a rising tide of media, technology, commercialism, and controversy.

How did the American media system become dominated by a few corporations, and why are structural problems like market failures routinely avoided in media policy discourse? By tracing the answers to many of these questions back to media policy battles in the 1940s, Victor Pickard explains how this happened and why it matters today. Drawing from extensive archival research, the book uncovers the American media system’s historical roots and normative foundations. His book charts the rise and fall of a forgotten media reform movement to recover alternatives and paths not taken. As much about the present and future as it is about the past, the book proposes policies for remaking media based on democratic values for the digital age.

    We sought to evaluate the caliber of education mainstream media provides the public about brain death. We reviewed articles published prior to July 31, 2015, on the most shared/heavily trafficked mainstream media websites of 2014 using the names of patients from two highly publicized brain death cases, "Jahi McMath" and "Marlise Muñoz." We reviewed 208 unique articles. The subject was referred to as being "alive" or on "life support" in 72% (149) of the articles, 97% (144) of which also described the subject as being brain dead. A definition of brain death was provided in 4% (9) of the articles. Only 7% (14) of the articles noted that organ support should be discontinued after brain death declaration unless a family has agreed to organ donation. Reference was made to well-known cases of patients in persistent vegetative states in 16% (34) of articles and 47% (16) of these implied both patients were in the same clinical state. Mainstream media provides poor education to the public on brain death. Because public understanding of brain death impacts organ and tissue donation, it is important for physicians, organ procurement organizations, and transplant coordinators to improve public education on this topic. © 2016 John Wiley & Sons A/S.

    Coal combustion by-products (CCB) include fly ash and bottom ash and are generated nationally at rates of 10{sup 8} Mg yr{sup -1}. Land applications of CCB have improved physicochemical properties of soil, yet inherent bulkiness and trace metal content of CCB often limit their use. Likewise, utilization of biosolids and manure as fertilizer can be problematic due to unfavorable nutrient ratios. A 2-yr field study evaluated environmental and technical parameters associated with CCB-organic waste utilization as growth media in turfgrass sod production. Experimental growth media formulated with CCB and organic waste and a sand-compost control mixture were uniformly spread at rates from 200 to 400 m{sup 3} ha{sup -1} and sprigged with hybrid bermudagrass (Cynodon dactylon (L.) Pers. x C. transvaalensis Burtt-Davy). Leaf clippings were collected and analyzed for total elemental content each year. In Year 2, growth media samples were collected during establishment 47 and 84 days after planting (DAP) and viable Escherichia coli organisms were quantified. At harvest (99 or 114 DAP), sod biomass and physicochemical properties of the growth media were measured. During sod propagation, micronutrient and metal content in leaf clippings varied by growth media and time. After 47 d of typical sod field management, viable E. coli pathogens were detected in only one biosolids-amended plot. No viable E. coli were measured at 84 DAP. In both years, sod biomass was greatest in media containing biosolids and fly ash. Following installation of sod, evaluations did not reveal differences by media type or application volume. Using CCB-organic waste mixes at the rates described herein is a rapid and environmentally safe method of bermudagrass sod production.

    Orodispersible films possess a great potential as a versatile platform for nanoparticle-loaded oral dosage forms. In this case, poorly water-soluble organic materials were ground in a stirred media mill and embedded into a polymer matrix. The aim of this study was the shortening of this manufacturing process by the integration of several process steps into a stirred media mill without facing disadvantages regarding the film quality. Furthermore, this process integration is time conserving due to the high stress intensities provided in the mill and applicable for high solids contents and high suspension viscosities. Two organic materials, the model compound Anthraquinone and the active pharmaceutical ingredient Naproxen were investigated in this study. Besides the impact of the film processing on the crystallinity of the particles in the orodispersible film, a particle load of up to 50% was investigated with the new developed processing route. Additionally, a disintegration test was developed, combining an appropriate amount of saliva substitute and a clear endpoint determination. In summary, high nanoparticle loads in orodispersible films with good particle size preservation after film redispersion in water as well as a manufacturing of the film casting mass within a few minutes in a stirred media mill was achieved.

    1995-07-01

    To gain insight on the controlling mechanisms for VOC transport in porous media, the relations among sorbent properties, sorption equilibrium and intraparticle diffusion processes were studied at the level of individual sorbent particles and laboratory columns for soil and activated carbon systems. Transport and sorption of VOCs and water vapor were first elucidated within individual dry soil mineral grains. Soil properties, sorption capacity, and sorption rates were measured for 3 test soils; results suggest that the soil grains are porous, while the sorption isotherms are nonlinear and adsorption-desorption rates are slow and asymmetric. An intragranular pore diffusion model coupled with the nonlinear Freundlich isotherm was developed to describe the sorption kinetic curves. Transport of benzene and water vapor within peat was studied; partitioning and sorption kinetics were determined with an electrobalance. A dual diffusion model was developed. Transport of benzene in dry and moist soil columns was studied, followed by gaseous transport and sorption in activated carbon. The pore diffusion model provides good fits to sorption kinetics for VOCs to soil and VOC to granular activated carbon and activated carbon fibers. Results of this research indicate that: Intraparticle diffusion along with a nonlinea sorption isotherm are responsible for the slow, asymmetric sorption-desorption. Diffusion models are able to describe results for soil and activated carbon systems; when combined with mass transfer equations, they predict column breakthrough curves for several systems. Although the conditions are simplified, the mechanisms should provide insight on complex systems involving transport and sorption of vapors in porous media.

    Community-based participatory media projects form a promising new strategy for mental health promotion that can help address the mental health-gap identified by the World Health Organization. (2008b) mhGAP, Mental Health Gap Action Programme: Scaling Up Care for Mental, Neurological and Substance Use Disorders. World Health Organization, Geneva. In this article we present an ethnographic study about a participatory media project that was developed to promote mental health in selected Dutch low socio-economic status neighborhoods. Through narrowcastings (group film viewings), participant observation and interviews we mapped the ways in which the media project effected and facilitated the collective sense-making process of the audience with regard to sources of stress impacting mental health and opportunities for action. These determinants of mental health are shaped by cultural dimensions, since the cultural context shapes everyday experiences of stress as well as the resources and skills to manage them. Our analysis shows that the media project engaged cultural resources to challenge stressful social scripts. We conclude that more attention should be paid to cultural narratives in a community to understand how health promotion strategies can support social resilience. © The Author 2015.

    As social media continues to grow as a way to communicate with the public about science missions, data and other STEM related topics, there has become a need for more organized and regimented Social Media programs and plans. In the Heliophysics science division at Goddard Space Flight Center we have been working on creating a template for social media programs which incorporates not just the goals for the program, as well as identifying an audience, but also deals with concerns about messaging, collaboration with other organizations, controversial topics, and evaluation. We hope that through creating a more unified approach we can develop a social media program that not only meets the needs of the audience but incorporates the needs of all of the different entities including the scientists, EPO Professionals and Office of Communications.

  14. Determining Citizens’ Opinions About Stories in the News Media

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available We describe a method whereby a governmental policy maker can discover citizens’ reaction to news stories. This is particularly relevant in the political world, where governments’ policy statements are reported by the news media and discussed by citizens. The work here addresses two main questions: whereabouts are citizens discussing a news story, and what are they saying? Our strategy to answer the first question is to find news articles pertaining to the policy statements, then perform internet searches for references to the news articles’ headlines and URLs. We have created a software tool that schedules repeating Google searches for the news articles and collects the results in a database, enabling the user to aggregate and analyse them to produce ranked tables of sites that reference the news articles. Using data mining techniques we can analyse data so that resultant ranking reflects an overall aggregate score, taking into account multiple datasets, and this shows the most relevant places on the internet where the story is discussed. To answer the second question, we introduce the WeGov toolbox as a tool for analysing citizens’ comments and behaviour pertaining to news stories.  We first use the tool for identifying social network discussions, using different strategies for Facebook and Twitter. We apply different analysis components to analyse the data to distil the essence of the social network users’ comments, to determine influential users and identify important comments.

    2011-01-01

    Public engagement in nanotechnology media products can lead to a greater interest in understanding of nanotechnology. A study was undertaken to determine middle school student engagement in Nanooze, a magazine featuring nanotechnology research that has been developed for a young adult audience. Teachers at 116 Detroit middle schools distributed two issues of the magazine to their students, and surveys were collected from 870 students after reading the magazines. Results suggest that the majority of students liked reading the magazine and learned something about nanotechnology. Engagement in nanotechnology led to understanding of nanotechnology. The Nanooze magazine was an effective medium for engaging middle school students in learning about nanotechnology.

    Social media is playing an ever-increasing role in informal science education due to its broad and ubiquitous reach, low overhead costs and versatility. However, to fully capitalize on the educational potential and dissemination capabilities of social media platforms, science organizations with a social media presence must move forward with an effective strategy that clearly outlines their audience, goals, messaging, content and growth objectives. It is also imperative that organizations perform a regular, rigorous evaluation of social media platform performance and conduct user engagement surveys and that they utilize this information to improve online performance and engagement. Here, we examine the IRIS EPO Facebook and Twitter platforms before and after the adoption of a more formal and detailed social media strategy. Some of the most effective growth tools thus far have been the content posting schedule, content media type guidelines and periodic platform performance evaluation. We also examine the results of a user survey assessing the efficacy of the IRIS social media presence. In the 8 months since the implementation of the new, more rigorous social media strategy the IRIS Facebook page following has grown by more than 90% and the Twitter page following has increased by almost 75%. This is a significant increase in growth as compared to the preceding years, which corresponds to significant increase in reach (Figure 1). By implementing a defined strategy with clear goals, scientific organizations can fully harness the educational potential offered by social media networks. [Figure 1: Facebook provided metrics showing the reach of the IRIS EPO Facebook page between 7/21/2014 and 7/22/2016. Although there are spikes in post reach in 2015 corresponding to newsworthy earthquake events, a significant increase in sustained reach occurred beginning in Dec of 2105 when the IRIS social media strategy was implemented.

    Kaja Žuran

    2013-12-01

    Full Text Available We live in a post-modern society, an information society, a society based around knowledge and participation, and above all in a media society. In a media culture where media holds a dominant position, we cannot overlook the emerging idea of a ‘media divide’ within the frame of media education, media literate individuals and the expansion of the traditional concept of media literacy. Firstly, we are in an era of technological revolution, and it is time to consider the meaning and function of media and how we experience it in our everyday life. Secondly, as a society we are subject to intense media invasion and we all need to learn how to use it to our benefit and apply a critical and autonomous perspective towards selecting media content. Otherwise the media divide between the media literate and illiterate will widen; but is there even a chance to overcome the supposed divide between those who are formally media educated and those who are not?

  6. Transport of oxidized multi-walled carbon nanotubes through silica based porous media: influences of aquatic chemistry, surface chemistry, and natural organic matter.

    Yang, Jin; Bitter, Julie L; Smith, Billy A; Fairbrother, D Howard; Ball, William P

    2013-12-17

    This paper provides results from studies of the transport of oxidized multi-walled carbon nanotubes (O-MWCNTs) of varying surface oxygen concentrations under a range of aquatic conditions and through uniform silica glass bead media. In the presence of Na(+), the required ionic strength (IS) for maximum particle attachment efficiency (i.e., the critical deposition concentration, or CDC) increased as the surface oxygen concentration of the O-MWCNTs or pH increased, following qualitative tenets of theories based on electrostatic interactions. In the presence of Ca(2+), CDC values were lower than those with Na(+) present, but were no longer sensitive to surface oxygen content, suggesting that Ca(2+) impacts the interactions between O-MWCNTs and glass beads by mechanisms other than electrostatic alone. The presence of Suwannee River natural organic matter (SRNOM) decreased the attachment efficiency of O-MWCNTs in the presence of either Na(+) or Ca(2+), but with more pronounced effects when Na(+) was present. Nevertheless, low concentrations of SRNOM (organic carbon) were sufficient to mobilize all O-MWCNTs studied at CaCl2 concentrations as high as 10 mM. Overall, this study reveals that NOM content, pH, and cation type show more importance than surface chemistry in affecting O-MWCNTs deposition during transport through silica-based porous media.

  7. Transport Gap and exciton binding energy determination in organic semiconductors

    The transport gap of an organic semiconductor is defined as the energy difference between the HOMO and LUMO levels in the presence of a hole or electron, respectively, after relaxation has occurred. Its knowledge is mandatory for the optimisation of electronic devices based on these materials. UV photoelectron spectroscopy (UPS) and inverse photoelectron spectroscopy (IPES) are routinely applied to measure these molecular levels. However, the precise determination of the transport gap on the basis of the respective data is not an easy task. It involves fundamental questions about the properties of organic molecules and their condensates, about their reaction on the experimental probe, and on the evaluation of the spectroscopic data. In particular electronic relaxation processes, which occur on the time scale of the photo excitation, have to be considered adequately. We determined the transport gap for the organic semiconductors PTCDA, Alq3, DIP, CuPc, and PBI-H4. After careful data analysis and comparison to the respective values for the optical gap we obtain values for the exciton binding energies between 0.1-0.5 eV. This is considerably smaller than commonly believed and indicates a significant delocalisation of the excitonic charge over various molecular units.

    2014-01-01

    Objective Conduct a social media content analysis of COPD patient education videos on YouTube. Methods A systematic search protocol was used to locate 223 videos. Two independent coders evaluated each video to determine topics covered, media source(s) of posted videos, information quality as measured by HONcode guidelines for posting trustworthy health information on the Internet, and viewer exposure/engagement metrics. Results Over half the videos (n=113, 50.7%) included information on medication management, with far fewer videos on smoking cessation (n=40, 17.9%). Most videos were posted by a health agency or organization (n=128, 57.4%), and the majority of videos were rated as high quality (n=154, 69.1%). HONcode adherence differed by media source (Fisher’s Exact Test=20.52, p=.01), with user-generated content (UGC) receiving the lowest quality scores. Overall level of user engagement as measured by number of “likes,” “favorites,” “dislikes,” and user comments was low (mdn range = 0–3, interquartile (IQR) range = 0–16) across all sources of media. Conclusion Study findings suggest that COPD education via YouTube has the potential to reach and inform patients, however, existing video content and quality varies significantly. Future interventions should help direct individuals with COPD to increase their engagement with high-quality patient education videos on YouTube that are posted by reputable health organizations and qualified medical professionals. Patients should be educated to avoid and/or critically view low-quality videos posted by individual YouTube users who are not health professionals. PMID:24659212

    Determine the incidence of ear infections in cochlear implant patients, evaluate the contribution of otitis media to complications, describe the bacteriology of otitis media in the cochlear implant population, the treatment provided at our center, and the long term outcome. Data collected included age at implantation, history of otitis media or ear tubes, etiology of hearing loss, inner ear anatomy, postoperative infections, time to infection, route of antibiotic administration, and interventions for infections. Categories of infection were acute otitis media, otitis media with effusion, tube otorrhea, meningitis, scalp cellulitis, and infection at the implant site. Middle ear infections were diagnosed in 37% of implanted ears. Extension of middle ear infections into the implant site occurred in 2.8% of all implants (n = 16). Of the 16 infected devices, 10 were successfully treated with antibiotic therapy and did not require explantation. The retained implant group and explanted group both included some middle ear microbes such as Haemophilus influenzae and Streptococcus pneumoniae, as well as skin flora such as Staphylococcus aureus. Otitis media in pediatric cochlear implant patients is a common event and usually does not lead to complications of the cochlear implant. However, when the ear infection spreads to the scalp and the implant site, it is still possible to eliminate the infection using antibiotic therapy, particularly when treatment is directed to the specific organism that is recovered from the infected space and the duration and route of antibiotic treatment is carefully considered.

LMTK32 was produced from modification of culture media Yeast Extract Mannitol Broth (YEMB with the aim of increasing the number of viable cells with the ability to promote the germination of maca seeds pelleted with the bacteria and reduce production costs. In the optimization process, the yeast extract and mannitol components of the LMC culture media were replaced by commercial sources of sucrose and glutamate, whose concentrations were determined in flasks by statistical design from Box-Behnken; in addition, the effect of the inoculum percentage on the time of biomass production was determined. Subsequently, it was determined at the bioreactor level that 28.57 h-1 was the adequate value of the volumetric oxygen transfer coefficient (kLa at 600 rpm, producing 1.28 x 10 11 CFU / mL. In the LMC M1 modified media, using 12.06 g / L-1 of sucrose, 11.50 g / L-1 of sodium glutamate and 10.9% of inoculant obtained 15x108 CFU / mL, increasing in 48% the number of viable cells with respect to the YEMB control treatment (7.8x10 8 CFU / mL. At the in vitro level, the pelleting of maca seeds with Pseudomonas sp. LMTK32 produced in bioreactor and in the modified media M1 favored its germination. From commercial organic substrates, efficient bacterial inoculants can be produced in the development of maca crops, without altering their ability to promote plant growth.

  5. LINGUISTIC FEATURES OF NATO’S MEDIA IMAGE (THE CASE STUDY OF BRITISH ONLINE PUBLICATIONS

    Directory of Open Access Journals (Sweden)

    Valuyskaya Olga Ruslanovna

    2014-12-01

    Full Text Available The paper investigates linguistic specific means of NATO's image making in online British leading newspapers. The case study involves news reports and analytical articles that represent explicit and implicit evaluation of the North Atlantic Treaty Organization. The investigation is based on the principles of the media linguistic approach and suggests the structural peculiarities of a media image that can be analyzed as a three-sided unit including positive, negative and neutral structural elements of image introduction into a media text. The NATO's image can be viewed as that of a geopolitical actor, creating its Natoland. Certain media topics are analyzed as creating positive and negative images of the NATO as a military organization. A finite list of positive and negative constituents to the Alliance's image is presented in the paper. It is assumed that the simplistic writer-reader model of interaction shapes certain elements of a media image that can be interpreted by a reader. The author distinguishes in the paper the principle constituents of an international organization in general, and the NATO in particular. Findings of the study demonstrate that the NATO's media image is interpreted by the readers as the conceptual entity of two key images: a peacemaker and a hawk that are restored on lexical and intertextual levels.

    . Strategic communication implicitly, perhaps even unintentionally, continues to rely on a classical understanding of organizations as “social units (or human groupings) deliberately constructed and reconstructed to seek specific goals” (Etzioni, 1964, p. 3). Assuming rather than exploring who...... the organization is, we argue, hinders a full explanation of how strategic communication works. Aiming to tackle this issue, we first present three ways in which the classical understanding of organizations is being theoretically challenged by organization studies and empirically challenged by new media, arguing...... that organizations are networked, sociomaterial, and contingent processes of meaning formation. Then we examine how the reconceptualization of the organization influences the concept of strategic communication, advocating that strategies should be seen as collaborative and networked flows (the how) of shared...

    2013-12-01

    Full Text Available The article is devoted to the problem of destructive trends in modern Russian mass media as well as to the information component in the activities of extremist and terrorist organizations. The destructive trends in the mass media manifest themselves in the escalation of animosity, aggression, creation of the cult of violence and xenophobia moods. Terrorist organizations use the mass media for their own purposes: they create the atmosphere of fear and tension in society, recruit new followers, mainly among the youth, which is a serious problem. It is important to use the positive potential of the mass media to counteract extremism and terrorism.

    2014-01-01

    The main aim of our study was to establish the prevalence of social networking accounts among a group of second-level students (aged 15-18 years), to determine whether they used privacy settings, and to examine their attitudes to various aspects of social media use in medicine. A descriptive study design was employed. The questionnaire was constructed specifically to address the attitudes of students to social media. No similar suitable validated questionnaire could be identified. The questionnaire consisted of 20 questions with a mixture of open answer, yes/no, and Likert scale response options. Participation was voluntary and anonymous. Second-level school children interested in studying medicine and aged between 15 and 18 years took part. An annual open day organized by the School of Medicine in University College Cork, Ireland, formed the setting. The day comprised a mixture of lectures, demonstrations, and practical sessions designed to give the students insight into life as a medical student. A total of 96 students attended, and all were handed the questionnaires. Of them, 88 students completed the survey. Overall, 90.9% of students had Facebook accounts and 53% had Twitter accounts. Of those with social media accounts, 14.8% reported having no privacy settings. Most respondents felt that unprofessional behavior on social media sites should be a factor considered in admission to medical schools. Serious consequences can result from lapses in best practice relating to social media behavior. Dedicated reflective learning modules need to be incorporated into undergraduate and postgraduate training programs as a matter of urgency. © 2013 Published by Association of Program Directors in Surgery on behalf of Association of Program Directors in Surgery.

    Social media data can provide valuable information regarding people's behaviors and health outcomes. Previous studies have shown that social media data can be extracted to monitor and predict infectious disease outbreaks. These same approaches can be applied to other fields including physical activity research and forensic science. Social media data have the potential to provide real-time monitoring and prediction of physical activity level in a given region. This tool can be valuable to public health organizations as it can overcome the time lag in the reporting of physical activity epidemiology data faced by traditional research methods (e.g. surveys, observational studies). As a result, this tool could help public health organizations better mobilize and target physical activity interventions. The first part of this paper aims to describe current approaches (e.g. topic modeling, sentiment analysis and social network analysis) that could be used to analyze social media data to provide real-time monitoring of physical activity level. The second aim of this paper was to discuss ways to apply social media analysis to other fields such as forensic sciences and provide recommendations to further social media research.

  11. Quantitative Determination of Organic Semiconductor Microstructure from the Molecular to Device Scale

    KAUST Repository

    Rivnay, Jonathan

    2012-10-10

    A study was conducted to demonstrate quantitative determination of organic semiconductor microstructure from the molecular to device scale. The quantitative determination of organic semiconductor microstructure from the molecular to device scale was key to obtaining precise description of the molecular structure and microstructure of the materials of interest. This information combined with electrical characterization and modeling allowed for the establishment of general design rules to guide future rational design of materials and devices. Investigations revealed that a number and variety of defects were the largest contributors to the existence of disorder within a lattice, as organic semiconductor crystals were dominated by weak van der Waals bonding. Crystallite size, texture, and variations in structure due to spatial confinement and interfaces were also found to be relevant for transport of free charge carriers and bound excitonic species over distances that were important for device operation.

    Abstract: Political agenda-setting research has shown that policy makers are responsive vis-à-vis media priorities. However, the mechanisms behind this effect have remained understudied so far. In particular, agenda-setting scholars have difficulties determining to what extent politicians react to media coverage purely because of the information it contains (information effect), and to what extent the effect is driven not by what the media say but by the fact that certain information is in th...

    As social media continues to grow as a way to communicate with the public about science missions, data and other STEM related topics, there has become a need for more organized and regimented Social Media programs and plans. In the Heliophysics science division at Goddard Space Flight Center we have been working on creating a template for social media programs which incorporates not just the goals for the program, as well as identifying an audience, but also deals with concerns about messaging, collaboration with other organizations, controversial topics, and evaluation. We hope that through creating a more unified approach we can develop a social media program that not only meets the needs of the audience but incorporates the needs of all of the different entities including the scientists, EPO Professionals and Office of Communications.

    Full Text Available Manufacturing organizations have become more complex in recent time as a result of technological advances. Communication among production workers operating in an environment marked by increased organizational complexity may require planning for the economically appropriate selection of network channels/media with enhanced productivity. This paper examines traditional and modern communication channels (media and their comparative advantages over one another in their adoption in manufacturing organizations. In this framework, six media (human messengers, mobile-phones, intranet, fixed-internet, mobile-internet, and private branch exchange [PBX] phone systems were subjected to analyses using five identified network patterns (all-channel, chain, Y, wheel, and circle of interactions in manufacturing organizations. Costs, benefits, and the utility of the channels were integrated into the model and utilized to determine the most sustainable media that could enhance productivity in industry. The developed model was implemented using expert data/information collected from the plastic production industry. The results of an availability assessment showed that the enhancement of productivity could be fully achieved by utilizing mobile phones and internet networks, but when considering overall utility, only mobile phones could bring about the desired productivity with 0.59 probability. The findings suggest that the system developed is robust in revealing how productivity might be affected by means of communication among industrial workers.

The findings indicated that digital media literacy remains low because of inadequate education, lack of opportunities and the patriarchal system in Indonesia.

  2. Determination of organ doses and effective doses in radiooncology

    International Nuclear Information System (INIS)

    Roth, J.; Martinez, A.E.

    2007-01-01

    Background and Purpose: With an increasing chance of success in radiooncology, it is necessary to estimate the risk from radiation scatter to areas outside the target volume. The cancer risk from a radiation treatment can be estimated from the organ doses, allowing a somewhat limited effective dose to be estimated and compared. Material and Methods: The doses of the radiation-sensitive organs outside the target volume can be estimated with the aid of the PC program PERIDOSE developed by van der Giessen. The effective doses are determined according to the concept of ICRP, whereby the target volume and the associated organs related to it are not taken into consideration. Results: Organ doses outside the target volume are generally < 1% of the dose in the target volume. In some cases, however, they can be as high as 3%. The effective doses during radiotherapy are between 60 and 900 mSv, depending upon the specific target volume, the applied treatment technique, and the given dose in the ICRU point. Conclusion: For the estimation of the radiation risk, organ doses in radiooncology can be calculated with the aid of the PC program PERIDOSE. While evaluating the radiation risk after ICRP, for the calculation of the effective dose, the advanced age of many patients has to be considered to prevent that, e.g., the high gonad doses do not overestimate the effective dose.

    2016-04-01

    Nowadays, there is an important trend in Europe for peat replacement with biochar in growing media formulation in order to reduce the environmental impact of peat exploitation. Hydrothermal carbonization (HTC) is a thermochemical process of converting organic feedstock into a high carbon rich solid product named hydrochar. It is performed in water mild temperature (180-260°C) under pressure conditions (2-6MPa) for 5-250 min. The reaction pressure is not controlled in the process and is autogenic with the saturation vapour pressure of water corresponding to the reaction temperature. In recent years, the possibility of subjecting organic wastes to HTC has attracted the scientific community attention due to their interesting advantages over other thermal treatments such as pyrolysis, torrefaction or gasification. The aim of the present paper is to study the possible use of two hydrochars produced by Ingelia (Spain) from sewage sludge and urban waste treatment as growing media material in horticulture. For this, thermal, chemical and hydrophysical properties were determined and compared with that of brown commercial peat.

    Nyhan, L; Begley, M; Mutel, A; Qu, Y; Johnson, N; Callanan, M

    2018-09-01

    The aim of this study was to develop a model to predict growth of Listeria in complex food matrices as a function of pH, water activity and undissociated acetic and propionic acid concentration i.e. common food hurdles. Experimental growth curves of Listeria in food products and broth media were collected from ComBase, the literature and industry sources from which a bespoke secondary gamma model was constructed. Model performance was evaluated by comparing predictions to measured growth rates in growth media (BHI broth) and two adjusted food matrices (zucchini purée and béarnaise sauce). In general, observed growth rates were higher in broth than in the food matrices which resulted in the model over-estimating growth in the adjusted food matrices. In addition, model outputs were more accurate for conditions without acids, indicating that the organic acid component of the model was a source of inaccuracy. In summary, a new predictive growth model for innovating or renovating food products that rely on multi-hurdle technology was created. This study is the first to report on modelling of propionic acid as an inhibitor of Listeria in combination with other hurdles. Our findings provide valuable insights into predictive model design and performance and highlight the importance of experimental validation of models in real food matrices rather than laboratory media alone.

    1984-01-01

    U(VI) determination by D.C. and differential pulse polarography was studied in the organic solutions derived from tributyl phosphate - diluent extracts (after separation from nitric acid media) along with a selected aprotic solvent (i.e.: propylene carbonate and N,N-dimethylacetamide). Miscibility of the TBP-diluent (e.g. cyclohexane, n-hexane, kerosene, n-dodecane) phase with nitric acid as supporting electrolyte, either by addition or already present in the extract was larger in DMA than in PC. In the DMA organic mixture, U(VI) exhibited a DPP peak due to a one electron step, with Esub(p)=-0.4 V (position connected with H 2 O and HNO 3 concentrations). This peak which was proportionnel to the U(VI) concentration from 5x10 -6 to 10 -3 M can be used to determinate directly hexavalent uranium in the industrial organic extraction phases TBP-diluent.

  13. Identifying ideology: media representations of the Irving Oil Refinery strike, 1994-1996

    Energy Technology Data Exchange (ETDEWEB)

    Steuter, E.C.

    1998-07-01

    Media coverage of a strike at the Irving Oil Refinery in Saint John, New Brunswick which began in 1994 and lasted until 1996 is used as a background for the examination of ideology, used here in the more inclusive sense, one in which the term suggests a frame of mind without the coherence and easily recognized label usually associated with political ideology. Central issues such as monopoly ownership of the New Brunswick media by the Irving Group of Companies (also owners of the refinery) , the ideological presentation of strikes in general, and the representation of changing labour relations in a post-industrial, globally-oriented society are analyzed to show how these issues influenced media coverage. Four New Brunswick dailies as well as selected English-language dailies from other parts of Canada have been scrutinized in an effort to determine their ideological stand. It was found that restrictive ideologies such as liberalism or conservatism are on the decline; instead, more inclusive ideologies like defeatism and individualism were prominently featured especially by the St. John Telegraph-Journal in New Brunswick and other papers outside the province. The most striking finding was that if the media coverage of the Irving Refinery strike is representative of public opinion, the current organization of the provincial political economy is accepted as 'natural' by a majority of New Brunswickers.

    Acute otitis media is the most common bacterial disease in children under five years; therefore, is one of the most common causes of pediatric consultation. Our objective was to determine the feasibility to consider this disease as a sentinel factor of medical attention. All the new cases of acute otitis media registered between 2008 and 2011 were collected and analyzed. Proportions, ratios, and incidence rates were determined. Also, the limits for proportions were calculated using mid P exact test. In children under five years, we observed 20 % of the cases of non-suppurative otitis media, and suppurative otitis media in 17 %. The reason for acute respiratory infection in relation to cases of otitis media in children of this age increased from 87:1 in 2008 to 53:1 in 2011. The reason of suppurative otitis media decreased in children under five years, even in 2009, when it was registered the highest number of new cases of acute respiratory infection. It was not feasible to determine if acute otitis media is a sentinel indicator; however, we could monitor medical attention indirectly.

  15. Studies on determination of stable elements in sea water and organisms

    International Nuclear Information System (INIS)

    Anon.

    1974-01-01

    The existing conditions of stable elements including Co, Zn, Cs, Ce and Eu in sea water were determined by adding radioactive tracers, and determination methods were discussed. 60 Co added to sea water revealed to be kept in solution in 93 per cent of non-filtrated sea water, and in 98 per cent of filtrated sea water. 65 Zn also added to sea water showed to be kept in solution in 97 per cent of both non-filtrated and filtrated sea water. Both elements seemed to exist as particle or ion smaller than 0.45 μ, which solved in sea water. On the other hand, in both Ce and Eu of rare earth elements, about 80 per cent of them presented in the residue, but the treatment of sea water by hydrochroric acid solubilized 80 to 90 per cent of them in filtrated sea water. One of the instrumental analysis, irradiation analysis by nuclear reactor, was applied: each of preconcentration procedure by ion exchange method for Co and Zn in sea water and drying up sample marine organisms to ash content combined with irradiation analysis. Chemical recovery of both 60 Co and 65 Zn in sea water by preconcentration procedure reached more than 95 per cent. As to marine organisms, Co, Zn, and Cs could be determined with only 100 to 200 mg. of ash content obtained from sample marine organisms showing 80 per cent of chemical yield of the carrier through whole the procedure of analysis in almost all the samples. The chemical recovery of Ce and Eu in sea water and marine organisms by the preconcentration procedure reached about 85 per cent, and chemical yield through whole the procedure of analysis was more than 60 per cent. Concentration factor of Co and Zn in fishes and shells, especially that of muscles, obtained by stable elements determination method was almost 10 times that by RI tracer method. The difference of chemical forms between RI tracer and stable isotope affected not only to physiological metabolism but also to food chains. (Kanao, K.)

    Atomic media have played a major role in studies of fast light. One of their attractive features is the ability to manipulate experimental parameters to control the dispersive properties that determine the group velocity of a propagating light pulse. We give an overview of the experimental methods, based on both linear and nonlinear atom–light interaction, that have produced superluminal propagation in atomic media, and discuss some of the significant theoretical contributions to the issues of pulse preservation and reconciling faster-than-light propagation and the principle of causality. The comparison of storage of light, enhanced Kerr nonlinearity and efficient wave mixing processes in slow and fast light atomic media illustrates their common and distinct features.

    polar solvents [15-18]. Hence, surfactants offer the possibility for organic reactions to occur in aqueous media, and from the viewpoint of green chemistry, water is safer, harmless and environmentally benign [19]. However, there has been limited work on the use of chiral micellar media to catalyze Diels-. Alder reactions.
