Knowledge Sharing Barriers in Vietnamese Higher Education Institutions (HEIS)
Publisher: IGI Global
Date: 2018
Abstract: This article explores the barriers for sharing knowledge effectiveness in Vietnamese higher education institutions (HEIs). Data were analyzed and triangulated from interviews, and focus groups from different universities and from government and university websites. Three significant factors were identified: bureaucratic management causing a lack of autonomy in decision-making, poor knowledge management systems, and weak in idual absorptive capacity. The results demonstrate these three factors as a significant influence on academic staff to share absorb and create new knowledge measured by journal publication output, and graduate quality. The research findings provide insights on the Vietnamese higher education landscape in the transition from a centralized economy to a market economy.

A MnII4cubane and a novel MnII10MnIII4cluster from the use of di-2-pyridyl ketone in manganese acetate chemistry
Publisher: Royal Society of Chemistry (RSC)
Date: 2009
DOI: 10.1039/B810835H
Abstract: The employment of di-2-pyridyl ketone, (py)2CO, in manganese(II) acetate chemistry is reported. The syntheses, crystal structures and magnetochemical characterisation are described for [MnII4(O2CMe)4{(py)2C(OH)O}4] () and [MnII10MnIII4O4(O2CMe)20{(py)2C(OH)O}4] (), where (py)2C(OH)O- is the monoanion of the gem-diol form of the ligand. The reaction of Mn(O2CMe)(2).4H2O with one equivalent of (py)2CO in Me2CO gives . Complex was obtained from the 1:1 reaction, in EtOH, between Mn(O2CMe)(2).4H2O and (py)2CO in the presence of NEt3. The tetranuclear molecule has a cubane topology with the MnII and the deprotonated oxygen atoms from the eta1:eta3:eta1:micro3 ligands occupying alternate vertices of the cube. The core of consists of two mixed valence cubane {MnII2MnIII2(micro3-O)2(micro3-OR'')2}4+ subunits that are linked through an unusual {MnII6(eta1:eta2:micro-O2CMe)6(eta2:eta2:micro3-O2CMe)2}4+ moiety via twelve eta1:eta1:micro MeCO2- groups. Some suggestions have been made concerning the possible assembly of from . The magnetic properties of in the 300-5 K range have been modelled with two J values, which reveal weak antiferromagnetic interactions within the molecule. Complex has a low spin ground state. This work demonstrates the flexibility, versatility and synthetic potential of combining (py)2CO with carboxylate ligands.

Critical Knowledge-Sharing Barriers and Knowledge Governance in Vietnamese Higher Education Institutions
Publisher: IGI Global
Date: 2021
DOI: 10.4018/978-1-7998-5772-3.CH011
Abstract: This research reveals the Vietnamese higher education institution (HEI) environment to examine knowledge sharing issues in developing countries. It compares knowledge management (KM) governance mechanisms in HEIs in a developing country with KM governance mechanisms used widely in developed countries. The authors position this research in the contextual of management capacity, infrastructure, and training issues. This chapter considers how strategies to develop and implement knowledge transfer are both led and governed in Vietnamese HEIs. Data were analyzed and triangulated from interviews, focus groups from different universities, and government and university websites in Vietnam. Four significant factors are identified in the KM process—bureaucratic management, hierarchical governance patterns, lack of autonomy, and underdeveloped KM systems—as contributory factors. The results are compared with extant KM governance literature and finds that knowledge is managed through bureaucratic mechanisms. Vietnamese academics rarely share their knowledge critical to research and research-led teaching.

Hybrid Germanium Iodide Perovskite Semiconductors: Active Lone Pairs, Structural Distortions, Direct and Indirect Energy Gaps, and Strong Nonlinear Optical Properties
Publisher: American Chemical Society (ACS)
Date: 22-05-2015
DOI: 10.1021/JACS.5B01025
Abstract: The synthesis and properties of the hybrid organic/inorganic germanium perovskite compounds, AGeI3, are reported (A = Cs, organic cation). The systematic study of this reaction system led to the isolation of 6 new hybrid semiconductors. Using CsGeI3 (1) as the prototype compound, we have prepared methylammonium, CH3NH3GeI3 (2), formamidinium, HC(NH2)2GeI3 (3), acetamidinium, CH3C(NH2)2GeI3 (4), guanidinium, C(NH2)3GeI3 (5), trimethylammonium, (CH3)3NHGeI3 (6), and isopropylammonium, (CH3)2C(H)NH3GeI3 (7) analogues. The crystal structures of the compounds are classified based on their dimensionality with 1–4 forming 3D perovskite frameworks and 5–7 1D infinite chains. Compounds 1–7, with the exception of compounds 5 (centrosymmetric) and 7 (nonpolar acentric), crystallize in polar space groups. The 3D compounds have direct band gaps of 1.6 eV (1), 1.9 eV (2), 2.2 eV (3), and 2.5 eV (4), while the 1D compounds have indirect band gaps of 2.7 eV (5), 2.5 eV (6), and 2.8 eV (7). Herein, we report on the second harmonic generation (SHG) properties of the compounds, which display remarkably strong, type I phase-matchable SHG response with high laser-induced damage thresholds (up to ∼3 GW/cm(2)). The second-order nonlinear susceptibility, χS(2), was determined to be 125.3 ± 10.5 pm/V (1), (161.0 ± 14.5) pm/V (2), 143.0 ± 13.5 pm/V (3), and 57.2 ± 5.5 pm/V (4). First-principles density functional theory electronic structure calculations indicate that the large SHG response is attributed to the high density of states in the valence band due to sp-hybridization of the Ge and I orbitals, a consequence of the lone pair activation.

Using ERG Theory as a Lens to Understand the Sharing of Academic Tacit Knowledge
Publisher: IGI Global
Date: 2013
DOI: 10.4018/978-1-4666-4679-7.CH010
Abstract: This chapter provides a direct view of the higher education environment in a transition economy. It reports research findings on barriers to sharing knowledge among Vietnamese academic and managerial colleagues, focusing on three factors: time, capital, and management capacity. It draws on data from focus groups and from in-depth interviews of Vietnamese members of faculty from six major universities. A key finding of this study is that work-overload leaves little time for collaborative research. Together with insufficient English skills and bureaucratic management, it contributes to measurable levels of cheating and corruption in education that in turn lead to low quality and quantity of international academic publications and of patents. This finding indicates that there is a strong link with both Existence, Relatedness, and Growth (ERG) theory and Maslow’s theory of need with both the quality and quantity of international publications produced by Vietnamese academics.
