A survey of ampullectomy practices
Stacy B Menees, Philip Schoenfeld, Hyungjin Myra Kim, Grace H Elta
World Journal of Gastroenterology , 2009,
Abstract: AIM: To investigate the endoscopic ampullectomy practices of expert biliary endoscopists.METHODS: An anonymous survey was mailed to 79 expert biliary endoscopists to assess ampullectomy practices.RESULTS: Forty six (58%) biliary endoscopists returned the questionnaire. Of these, 63% were in academia and in practice for an average of 16.4 years (± 8.6). Endoscopists performed an average of 1.1 (± 0.8) ampullectomies per month. Prior to ampullectomy, endoscopic ultrasound was “always” utilized by 67% of respondents vs “sometimes” in 31% of respondents. Empiric biliary sphincterotomy was not utilized uniformly, only 26% “always” and 37% “sometimes” performed it prior to resection. Fifty three percent reported “never” performing empiric pancreatic sphincterotomy prior to ampullectomy. Practitioners with high endoscopic retrograde cholangiopancreatography volumes were the most likely to perform a pancreatic sphincterotomy (OR = 10.9; P = 0.09). Participants overwhelmingly favored “always” placing a prophylactic pancreatic stent, with 86% placing it after ampullectomy rather than prior to resection (23%). Argon plasma coagulation was the favored adjunct modality (83%) for removal of residual adenomatous tissue. Practitioners uniformly (100%) preferred follow-up examination to be within 6 mo post-ampullectomy.CONCLUSION: Among biliary experts, there is less variation in ampullectomy practices than is reflected in the literature.
How Important Is ‘Accuracy’ of Surrogate Decision-Making for Research Participation?
Scott Y. H. Kim, H. Myra Kim, Kerry A. Ryan, Paul S. Appelbaum, David S. Knopman, Laura Damschroder, Raymond De Vries
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0054790
Abstract: Background There is a longstanding concern about the accuracy of surrogate consent in representing the health care and research preferences of those who lose their ability to decide for themselves. We sought informed, deliberative views of the older general public (≥50 years old) regarding their willingness to participate in dementia research and to grant leeway to future surrogates to choose an option contrary to their stated wishes. Methodology/Principal Findings 503 persons aged 50+ recruited by random digit dialing were randomly assigned to one of three groups: deliberation, education, or control. The deliberation group attended an all-day education/peer deliberation session; the education group received written information only. Participants were surveyed at baseline, after the deliberation session (or equivalent time), and one month after the session, regarding their willingness to participate in dementia research and to give leeway to surrogates, regarding studies of varying risk-benefit profiles (a lumbar puncture study, a drug randomized controlled trial, a vaccine randomized controlled trial, and an early phase gene transfer trial). At baseline, 48% (gene transfer scenario) to 92% (drug RCT) were willing to participate in future dementia research. A majority of respondents (57–71% depending on scenario) were willing to give leeway to future surrogate decision-makers. Democratic deliberation increased willingness to participate in all scenarios, to grant leeway in 3 of 4 scenarios (lumbar puncture, vaccine, and gene transfer), and to enroll loved ones in research in all scenarios. On average, respondents were more willing to volunteer themselves for research than to enroll their loved ones. Conclusions/Significance Most people were willing to grant leeway to their surrogates, and this willingness was either sustained or increased after democratic deliberation, suggesting that the attitude toward leeway is a reliable opinion. Eliciting a person’s current preferences about future research participation should also involve eliciting his or her leeway preferences.
Representation of Linguistic Information Determines Its Susceptibility to Memory Interference
Myra A. Fernandes,Jeffrey D. Wammes,Janet H. Hsiao
Brain Sciences , 2013, DOI: 10.3390/brainsci3031244
Abstract: We used the dual-task paradigm to infer how linguistic information is represented in the brain by indexing its susceptibility to retrieval interference. We measured recognition memory, in bilingual Chinese-English, and monolingual English speakers. Participants were visually presented with simplified Chinese characters under full attention, and later asked to recognize them while simultaneously engaging in distracting tasks that required either phonological or visuo-spatial processing of auditorily presented letters. Chinese speakers showed significantly greater memory interference from the visuo-spatial than phonological distracting task, a pattern that was not present in the English group. Such a pattern suggests that retrieval of simplified Chinese characters differentially requires visuo-spatial processing resources in Chinese speakers; these are compromised under dual-task conditions when such resources are otherwise engaged in a distracting task. In a secondary analysis, we showed the complementary pattern in a group of English speakers, whose memory for English words was disrupted to a greater degree from the phonological than visuo-spatial distracting task. Together, these results suggest the mode of representation of linguistic information can be indexed behaviorally by susceptibility to retrieval interference that occurs when representations overlap with resources required in a competing task.
Determinants of Individual Trust in Global Institutions: The Role of Social Capital and Transnational Identity  [PDF]
Harris H. Kim
Sociology Mind (SM) , 2012, DOI: 10.4236/sm.2012.23036
Abstract: The focus of this paper is to examine the determinants of individual-level trust in global institutional actors, namely the World Bank, the World Trade Organization, and multinational corporations (MNCs). This study is guided by two lines of inquiry. First, consistent with the social capital theory, it investigates the role of social or generalized trust in creating institutional trust. Second, in keeping with the extant literature on economic and cultural globalization, it also probes into how and to what extent transnational identity shapes people’s perception and evaluation of international organizations. Based on the Asian Barometer Survey (2003), a cross-national dataset covering 10 Asian countries (N = 8086), this study finds that both factors significantly shape the level of institutional trust, while controlling for a host of relevant variables. More specifically, logistic regression analyses reveal that the tendency to trust generalized others has a positive association with the degree of trust placed in institutional actors. Transnational identity, on the contrary, has the reverse effect. The implications of the empirical findings and the suggestions for future research are discussed.
How Do Network Size, Voluntary Association, and Trust Affect Civic Engagement? Evidence from the Asian Barometer Survey  [PDF]
Harris H. Kim
Advances in Applied Sociology (AASoci) , 2012, DOI: 10.4236/aasoci.2012.24033
Abstract: This study examines the role of social capital in shaping the individual likelihood of “civic engagement” defined specifically as informal and formal political participation. Based on a subset of the Asian Barometer Survey of Democracy, Governance and Development (2006), a representative cross-national dataset, it examines how and to what extent network size, voluntary association, generalized trust, and particularized trust differentially influence the political behaviors of the survey participants in Korea. The dependent variable is measured in terms of first, discussing political topics in an informal social context and, second, getting together with others in order to raise a political issue or sign a petition. Four independent variables are measured: 1) the size of egocentric network; 2) the membership in voluntary organizations and formal groups; 3) the degree of trust placed in generalized others (i.e., strangers); and 4) the extent to which survey respondents place their trust in particularized others (those with whom one has a personal relationship). Quantitative analyses show that, ceteris paribus, network size and voluntary association have a strong causal impact on both outcome variables. Generalized trust is found to be a non-significant factor, however, while particularized trust has a contingent effect. Along with the interpretation of statistical results, their broad theoretical implications are also discussed.
What Do Teachers Desire in Music Digital Textbook for Leaner-Centered Curriculum?  [PDF]
Sahoon H. Kim
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.32001
Abstract:

We are living in the 21st century that requires us to know how to integrate paper based curricula into interactive media. The purpose of the study is to provide exemplary cases that music teachers hope for their music classes through using Digital Textbook. For this purpose, two times of interviews with ten music teachers in South Korea were conducted. Case study and grounded theory methodology were adopted as a tool for analyzing the data. As a result, the teachers’ desires for Digital Textbook were categorized into two perspectives: learner-centered learning, and collaborative learning & connection with open sources.

Swimming upstream: navigating ethical practices in the creation of a participatory youth media workshop
Myra Margolin
Les Ateliers de l’éthique , 2009,
Abstract: Despite the growing popularity of participatory video as a tool for facilitating youth empower- ment, the methodology and impacts of the practice are extremely understudied. This paper des- cribes a study design created to examine youth media methodology and the ethical dilemmas that arose in its attempted implementation. Specifically, elements that added “rigor” to the study (i.e., randomization, pre- and post-measures, and an intensive interview) conflicted with the fun- damental tenets of youth participation. The paper concludes with suggestions for studying par- ticipatory media methodologies that are more in line with an ethics of participation.

Revista chilena de infectología , 2003, DOI: 10.4067/S0716-10182003000100001
Abstract: a retrospective study by means of indirect immunofluorescence was carried out to detect igm antibodies against chlamydia pneumoniae and mycoplasma pneumoniae in seronegative patients for hantavirus, with characteristics symptoms of atypical pneumonia. the final results indicate that the prevalence of c. pneumoniae reaches 8,6% and m. pneumoniae is equivalent to 17,1% of the patients studied. by this we can be aware of the importance of these agents in our media, and the necessity of having rapid laboratory techniques that allow an opportune differential diagnosis in pulmonary syndrome for hantavirus and other pathologies that cause similar symptoms, mainly atypical pneumonia

Revista chilena de infectología , 2008,
Abstract: La susceptibilidad in vitro de Staphylococcus aureus adquirido, tanto en el ambiente hospitalario como en la comunidad, debe ser monitorizada periódicamente por su continua evolución. Objetivos: Conocer la susceptibilidad antimicrobiana de cepas de S. aureus aisladas en Valdivia, determinar la prevalencia de cepas resistentes a meticilina y sus respectivos patrones de resistencia, analizar la evolución de esta susceptibilidad a través de los a os. Material y Métodos: Se evaluaron 278 cepas de S. aureus: 136 obtenidas de pacientes hospitalizados, 50 de pacientes ambulatorios y 92 de portadores. Los antimicrobianos ensayados fueron: penicilina, oxacilina, vancomicina, gentamicina, ciprofloxacina, lincomicina y eritromicina In vitro susceptibility of nosocomial and community acquired strains of Staphylococcus aureus must be periodically evaluated because of its continuous evolution. Aim: To know the antimicrobial susceptibility of S. aureus isolated in Valdivia, to determine the prevalence of methicillin resistance and global patterns of resistance and to compare the evolution of the susceptibility along the years. Material and Methods: A total of 278 S. aureus strains were evaluated: 136 obtained from hospitalized patients, 50 belonged to outpatients and 92 to healthy carriers. Antimicrobial agents tested were: penicillin, oxacillin, vancomycin, gentamycin, ciprofloxacin, lincomycin and erythromycin. Results: Thirty three, 28 and 1.1% of strains isolated from hospitalized, outpatients and carriers, respectively, were methicillin-resistant. Six resistance patterns were found. No vancomycin resistant strain was isolated. Comment: It is worrisome that 2% of S. aureus strains obtained from hospitalized patients showed intermediate resistance to vancomycin
