Analyzing Effects of Institutional Quality on Banking Stability: Evidence from Asean Countries
Purpose: The aim of this study is to examine the effect of institutional quality on bank stability using bank-level data from 2010 to 2020.
Theoretical framework: The study considers institutions from the perspective of governance institutions. Accordingly, the concept of government institutions is related to the country's organizational foundation in terms of governance, implying institutional quality.
Design/methodology/approach: The study uses GMM method and also choose the Zscore as the primary variable for bank stability.
Findings: The results show that institutional quality increases the stability of banks. Moreover, with the threshold model, the results show that countries with institutional quality above the threshold will increase the stability of banks. In addition, macroeconomic and banking characteristics variables such as total assets, income diversification, quality of control, inflation, and GDP growth rate have a high significance in the model.
Research, Practical & Social implications: The study shows The study's empirical results have specific policy implications for the Government in implementing policies related to institutional quality to improve bank stability.
Originality/value: there are not many researches done to investigate institutional quality to improve bank stability. Moreover, from economic crisis, the matter of banking stability is among main concerns of many researches. Second, previous researches just focus on the aspect of corruption and ignore other aspects or other factors. That’s why authors conduct this research
A Murnaghan-Nakayama rule for Grothendieck polynomials of Grassmannian type
We consider the Grothendieck polynomials appearing in the K-theory of
Grassmannians, which are analogs of Schur polynomials. This paper aims to
establish a version of the Murnaghan-Nakayama rule for Grothendieck polynomials
of the Grassmannian type. This rule allows us to express the product of a
Grothendieck polynomial with a power sum symmetric polynomial into a linear
combination of other Grothendieck polynomials.Comment: 10 pages, 7 figure
Super Bound States in the Continuum on Photonic Flatbands: Concept, Experimental Realization, and Optical Trapping Demonstration
In this work, we theoretically propose and experimentally demonstrate the
formation of a super bound state in a continuum (BIC) on a photonic crystal
flat band. This unique state simultaneously exhibits an enhanced quality factor
and near-zero group velocity across an extended region of the Brillouin zone.
It is achieved at the topological transition when a symmetry-protected BIC
pinned at merges with two Friedrich-Wintgen quasi-BICs, which arise from
destructive interference between lossy photonic modes of opposite symmetries.
As a proof-of-concept, we employ the super flat BIC to demonstrate
three-dimensional optical trapping of individual particles. Our findings
present a novel approach to engineering both the real and imaginary components
of photonic states on a subwavelength scale for innovative optoelectronic
devices
De novo ChIP-seq analysis
Methods for the analysis of chromatin immunoprecipitation sequencing (ChIP-seq) data start by aligning the short reads to a reference genome. While often successful, they are not appropriate for cases where a reference genome is not available. Here we develop methods for de novo analysis of ChIP-seq data. Our methods combine de novo assembly with statistical tests enabling motif discovery without the use of a reference genome. We validate the performance of our method using human and mouse data. Analysis of fly data indicates that our method outperforms alignment based methods that utilize closely related species
Chemical composition and antibacterial activities of the ethanol extracts from the leaves and tubers of Amorphophallus pusillus
Amorphophallus pusillus is a rare species which is found only in Binh Chau-Phuoc Buu Nature Reserve. In this study, we determined 7 flavonoid compounds in tuber and leaf of A. pusillus, including of vitexin, orientin, vitexin 2?-O-glucoside, cyanidin 3-O-rutinoside, pelargonidin 3-O-glucoside, schaftoside, and peonidin 3-O-rutinoside via liquid chromatography-mass spectrometry (LC-MS). Furthermore, we have proved the antibacterial activities of ethanol extracts obtained from A. pusillus leaves and tubers in the first time. The data revealed that ethanol extracts could inhibit the growth of 6 tested microorganisms, such as Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa, Salmonella enteritidis, Salmonella typhimurium, and Staphylococcus aureus. These data suggested the potential application of ethanol extracts isolated from this species as natural antimicrobial agents for treatment of infection caused by bacteria, especially in dermatologic and enteric infections
ANTECEDENTS OF TOURISTS’ LOYALTY: THE ROLE AND INFLUENCE OF TOURISM PRODUCTS, DESTINATION IMAGE IN HOIAN WORLD CULTURAL HERITAGE SITE
The study’s aim is to examine the antecedents of destination loyalty, and considers the role and influence of tourism
products and destination image to international tourisms’ loyalty in case of HoiAn World Cultural Heritage Site. The study
suggested an integrated approach to understand tourists’ loyalty model and investigate the empirical evidence about the
relationship among tourism products, destination image, risk perception, tourist experience, destination satisfaction and tourists’
loyalty. This study also mentions important questions concerning how tourism products, destination image, tourist experience,
risk perception, and tourists’ satisfaction affect tourists’ loyalty. Smart PLS3 is used to estimate and test the relationships in the
research model. Mediation analysis and importance performance matrix analysis are also used to consider clearly the relationship
between the constructs of research model. The study’s results indicate that tourism products, destination image, tourism
experience, risk perception, and satisfaction are antecedents of international tourists’ loyalty in Hoi An World Cultural Heritage
Site. And in them, tourism products affect significantly positively to destination imagine and satisfaction, beside destination
image and satisfaction hold the role of mediator in this relationship. Implementing IPMA to identify the predecessors that have
relatively high importance for loyalty but also a relatively low performance. The results pointed out that the constructs as
satisfaction, tourism product, risk perception and image have a high importance for the tourist loyalty. The study added the
antecedent of tourism products and risk perception to the model and could enrich the literature, pointing to be possibility of a
destination loyalty model that can be applied to various contexts, especially after COVID- 19 pandemic. The study also discussed
theoretical and managerial implications for marketing tourism
EVALUATION OF CITIZENS' SATISFACTION WITH THE QUALITY OF PUBLIC ADMINISTRATIVE SERVICES IN THE MEKONG DELTA, VIETNAM
Citizen satisfaction is one of the essential factors reflecting the quality of public administrative services provided by
state administrative agencies. The study aims to assess citizens' satisfaction with the quality of public administrative services in
the Mekong Delta, Vietnam. Research data were collected from survey results using questionnaires from 792 survey samples in
the Mekong Delta, Vietnam. Research results have shown that citizens are satisfied with the quality of public administrative services
in the Mekong Delta, Vietnam. At the same time, there are six factors affecting citizens' satisfaction with the quality of public
administrative services, including (1) Reliability; (2) Service capacity of staff; (3) Service attitude of staff; (4) The service level of
staff; (5) Infrastructure; (6) Administrative procedures. Research results show no difference in citizen satisfaction in gender, age
and education groups. Besides, the survey area group has a difference in citizen satisfaction. The research results have theoretical
and practical significance for public administration in Vietnam. From the research results, several contents are discussed and
proposed to improve citizens' satisfaction with the quality of public administrative services in the Mekong Delta, Vietnam
