    The House of Kwee Sik Poo an Indonesian-Chinese Merchant From Pasuruan

    Full text link
    The Kwee family is an old Indonesian-Chinese family from Pasuruan, in East Java, and one of a few merchant families of either Chinese or Arab ethnic origin which led successful lives in this small town in the nineteenth century. From their Chinese ancestral village, Liu Chuan in Fujian province, China, a Kwee ancestor travelled to Southeast Asia and settled in Pasuruan, probably in the eighteen century. As with many families who held important positions in the ethnic Chinese community, it also owned large homes, mostly in a mixed architectural style, called ā€œeclecticismā€ and later in what was known as ā€œthe Indies-empire styleā€. The early family history is still clouded in mystery, as not much concrete information has survived. Its descendants worked hard and prospered and dealt among economic undertakings such as sugar production, opium sales, buying and selling of property and land as well as running pawnshops

    OBJECTIVE. The purpose of this study is to investigate the frequency of funded research published in major radiology journals and to determine whether funding is associated with the article citation rate. MATERIALS AND METHODS. A total of 600 consecutive original research articles published in three journals-AJR, Radiology, and European Radiology-were included. Linear regression analysis was performed to determine the association between research funding and the article citation rate, as adjusted for journal, continent of origin of the first author, subspecialty, study findings included in the article title, number of authors, immediate open access publication, and time since publication online. RESULTS. Funding was declared for 286 of 600 included articles (47.7%). Sources of funding were as follows: federal sponsorship (29.4%), a nonprofit foundation (16.4%), both federal sponsorship and a nonprofit foundation (16.1%), private industry (10.1%), intramural institutional research funding (9.8%), and other funding sources (18.2%). Articles with first authors whose continent of origin was Europe (p <0.001), vascular and interventional radiology articles (p <0.001), and articles published in AJR (p <0.001) were significantly more frequently unfunded than funded. Articles published in Radiology were significantly more frequently funded (p <0.001). The citation rate was not significantly different between funded and unfunded articles (p = 0.166). In adjusted linear regression analysis, funding was not significantly associated with the citation rate (beta coefficient,- 0.31; 95% CI,-3.27 to 2.66; p = 0.838). CONCLUSION. Almost half of the research articles published in major radiology journals declared funding, a proportion that has increased compared with findings from previous studies (17% of articles in a study from 1994 and 26.9% of articles in a study of literature published between 2001 and 2010). Most funded articles received support from federal sponsors or nonprofit foundations, whereas only a minority of funded articles were supported by private industry. Funding was not associated with a higher citation rate

    Objective: To investigate whether there is a difference in citation rate between open access and subscription access articles in the field of radiology. Methods: This study included consecutive original articles published online in European Radiology. Pearson Ļ‡2, Fisherā€™s exact, and Mann-Whitney U tests were used to assess for any differences between open access and subscription access articles. Linear regression analysis was performed to determine the association between open access publishing and citation rate, adjusted for continent of origin, subspeciality, study findings in article title, number of authors, number of references, length of the article, and number of days the article has been online. In a secondary analysis, we determined the association between open access and number of downloads and shares. Results: A total of 500 original studies, of which 86 (17.2%) were open access and 414 (82.8%) were subscription access articles, were included. Articles from Europe or North America were significantly more frequently published open access (p = 0.024 and p = 0.001), while articles with corresponding authors from Asia were significantly less frequently published open access (p < 0.001). In adjusted linear regression analysis, open access articles were significantly more frequently cited (beta coefficient = 3.588, 95% confidence interval [CI] 0.668 to 6.508, p = 0.016), downloaded (beta coefficient = 759.801, 95% CI 630.917 to 888.685, p < 0.001), and shared (beta coefficient = 0.748, 95% CI 0.124 to 1.372, p = 0.019) than subscription access articles (beta coefficient = 3.94, 95% confidence interval 1.44 to 6.44, p = 0.002). Conclusion: Open access publishing is independently associated with an increased citation, download, and share rate in the field of radiology. Key Points: ā€¢ A minority of articles are currently published open access in European Radiology. ā€¢ European and North American authors tend to publish more open access articles than Asian authors. ā€¢ Open access publishing seems to offer an independent advantage in terms of citation, download, and share rate

    Purpose: To investigate gender diversity in editorial boards among a wide range of radiology-related journals, the trend in time, and its association with the journal's impact factor (IF). Method: The Journal Citation Reports website was searched for radiology-related journals journals with IF>2.0. Gender of the editor-in-chief and all editorial board members as listed on each journal's official website were determined. Mann-Whitney U test and Spearman's rho test were used for statistical analyses. Current data were compared to historical data. Results: Fifty-seven radiology-related journals were included. The names of 4176 persons were extracted. A woman was in charge as the only editor-in-chief in 5 of 57 journals (8.8%). Median percentage of female editorial board members was 21.5% (range 3.2%-52.0%). Female editorial board members were in the majority in only two journals, with proportions of 51.4% and 52.0%. IFs between journals with female and male editors-in-chief were not significantly different (median 3.00, range 2.21-7.82 vs. median 3.31, range 2.02-10.98; P = 0.951). There was no significant association between percentage of female editorial board members and a journal's IF (Spearman's rho = -0.019, P = 0.889). The proportion of women has increased compared to historical data. Conclusion: Women are underrepresented in a wide range of radiology-related journals. Comparison with historical data shows that the proportion of women on editorial boards has increased. Nevertheless, gender composition of the editorial board shows no association with IF. This suggests similar gender bias exists across a broad spectrum of high impact factor journals, with no added bias in journals with higher IF

    Purpose There has been no recent investigation on nuclear medicine research funding. Our purpose was to investigate the frequency of funded nuclear medicine research and whether funding is associated with citation impact. Methods Original articles published in three major nuclear medicine journals were assessed for funding. Results 337 (56.2%) of 600 articles declared funding, which included federal sponsoring (47.6%), non-profit foundations (22.5%), intramural institutional foundations (16.0%), and private industry (13.9%). In linear regression analysis (adjusted for journal, continent of origin, mentioning of study findings in the article title, number of authors, open access publishing, and time since online publication), funding was significantly associated with citation impact (beta coefficient = 5.111, 95% CI, 1.005-9.217, P = 0.015). Conclusions More than half of research in major nuclear medicine journals declared funding. The far majority were supported federally, followed by non-profit foundations, intramural institutional foundations, and private industry. Funding was associated with higher citation impact

    Pion Form Factors in Holographic QCD

    Full text link
    Using a holographic dual model of QCD, we compute the pion electromagnetic form factor F_pi(Q^2) in the spacelike momentum transfer region, as well as pion couplings to vector mesons g_rho^(n) pi pi. Spontaneous and explicit chiral symmetry breaking are intrinsic features of this particular holographic model. We consider variants with both ``hard-wall'' and ``soft-wall'' infrared cutoffs, and find that the F_pi(Q^2) data tend to lie closer to the hard-wall model predictions, although both are too shallow for large Q^2. By allowing the parameters of the soft-wall model (originally fixed by observables such as m_rho) to vary, one finds fits that tend to agree better with F_pi(Q^2). We also compute the pion charge radius for a variety of parameter choices, and use the values of f^(n)_rho, g_{rho^(n) pi pi} and m^(n)_rho to observe the saturation of F_pi(0) by rho poles.Comment: 17 pages, 2 figures, revised fits using consistent normalization of f_pi.

    AdS/QCD and Light Front Holography: A New Approximation to QCD

    Get PDF
    The combination of Anti-de Sitter space (AdS) methods with light-front holography leads to a semi-classical first approximation to the spectrum and wavefunctions of meson and baryon light-quark bound states. Starting from the bound-state Hamiltonian equation of motion in QCD, we derive relativistic light-front wave equations in terms of an invariant impact variable zeta which measures the separation of the quark and gluonic constituents within the hadron at equal light-front time. These equations of motion in physical space-time are equivalent to the equations of motion which describe the propagation of spin-J modes in anti--de Sitter (AdS) space. Its eigenvalues give the hadronic spectrum, and its eigenmodes represent the probability distributions of the hadronic constituents at a given scale. Applications to the light meson and baryon spectra are presented. The predicted meson spectrum has a string-theory Regge form M2=4Īŗ2(n+L+S/2){\cal M}^2 = 4 \kappa^2(n+L+S/2); i.e., the square of the eigenmass is linear in both L and n, where n counts the number of nodes of the wavefunction in the radial variable zeta. The space-like pion and nucleon form factors are also well reproduced. One thus obtains a remarkable connection between the description of hadronic modes in AdS space and the Hamiltonian formulation of QCD in physical space-time quantized on the light-front at fixed light-front time. The model can be systematically improved by using its complete orthonormal solutions to diagonalize the full QCD light-front Hamiltonian or by applying the Lippmann-Schwinger method in order to systematically include the QCD interaction terms.Comment: Invited talk, presented by SJB at the Fifth International Conference On Quarks and Nuclear Physics (QNP09), 21-26 Sep 2009, Beijing, China.

    Conversion of brain cytosol profile from fetal to adult type during the perinatal period: Taurine-NAA exchange

    Get PDF
    Mammals face drastic environmental changes at birth. Appropriate adjustments of various systems must take place rapidly to accommodate this once in a life time event. The brain undergoes significant adjustments as well, the most obvious of which is in its need to meet the drastic increase in energy consumption at the neuronal cell membrane due to the explosive increase in neural activities after birth. Actual changes were found to be taken place in two systems, namely, acid base balance control and cytosolic energy transport. The adjustments are accomplished by converting cytosol microenvironment from a taurine rich fetal type environment to an N-acetyl-aspartate (NAA) rich adult type environment during the post-natal period. High concentrations of taurine are necessary to provide effective buffering in the fetal brain, because the fetus cannot utilize the adult type of pCO2 dependent acidā€“base balance control system, namely respiration driven pCO2 changes. To accommodate the significantly higher demand of energy consumption at the membrane due to the increased neuronal activities, taurine has to be replaced by NAA, since the latter facilitates HEP transport from mitochondria to the membrane by passive diffusion
