How University Departmens respond to the Rise of Academic Entrepreneurship? The Pasteur's Quadrant Explanation

This paper examines how universities can develop a new organizational structure to cope with the rise of academic entrepreneurship. By deploying the Pasteurian quadrant framework, knowledge creation and knowledge utilization in universities are measured. The relationships between university antecedents, Pasteurian orientation, and research performance are analyzed. A survey of university administrators and faculty members collected 634 responses from faculty members in 99 departments among 6 universities. The findings indicate that university antecedents of strategic flexibility and balancing commitment contribute to a greater Pasteurian orientation in university departments. The higher degree of Pasteurian orientation has significantly positive impacts on the performance both of knowledge creation and knowledge utilization. Moreover, the Pasteurian orientation acts as a mediator between university antecedents and research performance. Using cluster analysis, the departments are categorized into four groups. The differences between university- and department- factors in these four groups are examined and discussed. We conclude that not all university departments should move toward the Pasteurian group, and there are specific organizational and disciplinary factors resulting in mobility barriers among groups. Policies to encourage academic entrepreneurship should consider these mobility barriers, along with this new governance of science.Academic entrepreneurship, Pasteur’s quadrant, research excellence, research commercialization

High expression FUT1 and B3GALT5 is an independent predictor of postoperative recurrence and survival in hepatocellular carcinoma.

Cancer may arise from dedifferentiation of mature cells or maturation-arrested stem cells. Previously we reported that definitive endoderm from which liver was derived, expressed Globo H, SSEA-3 and SSEA-4. In this study, we examined the expression of their biosynthetic enzymes, FUT1, FUT2, B3GALT5 and ST3GAL2, in 135 hepatocellular carcinoma (HCC) tissues by qRT-PCR. High expression of either FUT1 or B3GALT5 was significantly associated with advanced stages and poor outcome. Kaplan Meier survival analysis showed significantly shorter relapse-free survival (RFS) for those with high expression of either FUT1 or B3GALT5 (P = 0.024 and 0.001, respectively) and shorter overall survival (OS) for those with high expression of B3GALT5 (P = 0.017). Combination of FUT1 and B3GALT5 revealed that high expression of both genes had poorer RFS and OS than the others (P < 0.001). Moreover, multivariable Cox regression analysis identified the combination of B3GALT5 and FUT1 as an independent predictor for RFS (HR: 2.370, 95% CI: 1.505-3.731, P < 0.001) and OS (HR: 2.153, 95% CI: 1.188-3.902, P = 0.012) in HCC. In addition, the presence of Globo H, SSEA-3 and SSEA-4 in some HCC tissues and their absence in normal liver was established by immunohistochemistry staining and mass spectrometric analysis

Preliminary Neotectonic Map of Onshore-offshore Taiwan

International audienceThe diversity of the research in earth sciences leads to a multisource approach to investigate the surroundings of Taiwan. Various data sets combined by a Geographical Information System (GIS) enable us to propose an intergrated neotectonic map of onshore-offshore Taiwan. Several technical problems arise during the compilation of this map, such as the homogeneity of scales, projections and geodetic systems used, the validity and precision of each data set (line and pixel) and document, and the integration of qualitative and quantitative documents.Various types of information are taken into account in this approach, such as topography and bathymetry, geology (lithology, structure), geophysics (gravimetry, magnetism, etc.), geodesy (levelling, GPS, etc.), remote sensing and field works. This multisource approach has been applied to data sets both onland and offshore Taiwan, and has resulted in a preliminary neotectonic map of onshore-offshore Taiwan. This map provides a better comprehension of the geodynamic phenomena that affect Taiwan, and contributes significantly to the relations of the offshore structures and their corresponding reactivated extensional structures onshore (for instance, the Tainan, Taihsi, Okinawa, and Huatung basins).This document should benefit both academic research (structural and active fault maps) as well as the applied geological implications (such as natural hazards mapping and evaluation of geotechnic works)

Thermal and angular dependence of next-generation photovoltaics under indoor lighting

Next-generation photovoltaic technologies such as dye-sensitized solar cells, organic thin-film photovoltaics and perovskite solar cells are promising to efficiently harvest ambient light energy. However, more and deeper understanding of their photovoltaic characteristics is essential to create new applications under room light illumination. In this study, for the first time, the difference in temperature coefficients and angular dependence of photovoltaic parameters for the large-area devices are investigated systematically under the compact fluorescent lamp and light-emitting diode light. These emerging photovoltaic devices, compared with the single crystalline silicon solar cells, not only have higher open-circuit voltage (up to approximate 1 V) and better power conversion efficiency (in the range of 9.2% ~ 22.6%) but also exhibit less temperature dependent voltage and output power (< −0.6% °C−1), as well as broader angular response (over 75 degrees). The state-of-the-art dye-sensitized and organic thin-film devices also show advantageously positive temperature coefficients of current, and the latter even has positive thermal dependence of fill factor. These features suggest the next-generation photovoltaic devices are more favorable than the conventional crystalline silicon solar cells for real-life indoor applications

Ten-year epidemiology and risk factors of cytomegalovirus infection in hematopoietic stem cell transplantation patients in Taiwan

Background: Cytomegalovirus (CMV) can cause infection and critical diseases in hematopoietic stem cell transplantation (HSCT) recipients. This study aimed to explore the cumulative incidence and risk factors for CMV infection and disease among HSCT recipients in Taiwan. Methods: This retrospective cohort study using the Taiwan Blood and Marrow Transplantation Registry (TBMTR) included HSCT recipients between 2009 and 2018 in Taiwan. The primary outcome was cumulative incidence of CMV infection or disease at day 100 after HSCT. Secondary outcomes included day 180 cumulative incidence of CMV infection or disease, infection sites, risk factors for CMV infection or disease, survival analysis, and overall survival after CMV infection and disease. Results: There were 4394 HSCT recipients included in the study (2044 auto-HSCT and 2350 allo-HSCT). The cumulative incidence of CMV infection and disease was significantly higher in allo-HSCT than in auto-HSCT patients at day 100 (53.7% vs. 6.0%, P < 0.0001 and 6.1% vs. 0.9%, P < 0.0001). Use of ATG (HR 1.819, p < 0.0001), recipient CMV serostatus positive (HR 2.631, p < 0.0001) and acute GVHD grades ≥ II (HR 1.563, p < 0.0001) were risk factors for CMV infection, while matched donor (HR 0.856, p = 0.0180) and myeloablative conditioning (MAC) (HR 0.674, p < 0.0001) were protective factors. Conclusion: The study revealed a significant disparity in terms of the incidence, risk factors, and clinical outcomes of CMV infection and disease between auto and allo-HSCT patients. These findings underscore the importance of considering these factors in the management of HSCT recipients to improve outcomes related to CMV infections

High efficiency nondoped deep-blue organic light emitting devices based on imidazole-π-triphenylamine derivatives

High-performance deep-blue emitting phenanthroimidazole derivatives with a structure of donor-linker-acceptor were designed and synthesized. By using different linkers and different linking positions, four deep-blue emitters were obtained and used as emitters or bifunctional hole-transporting emitters in OLEDs. Such devices show low turn-on voltages (as low as 2.8 V), high efficiency (2.63 cd/A, 2.53 lm/W, 3.08%), little efficiency roll-off at high current densities, and stable deep-blue emissions with CIE y < 0.10. Performances are among the best comparing to recently reported deep-blue emitting devices with similar structures. The results suggest that the combination of the phenanthroimidazole and the donor-linker-acceptor structure can be an important approach for developing high performance deep-blue emitters in particular for lighting applications. © 2011 American Chemical Society
