Prudential liquidity standards in Asia
Since the outbreak of the global financial crisis, regulators have increased their focus on the ability of banks to measure and manage liquidity risk. In December 2009, the Basel Committee on Banking Supervision (the Basel Committee) identified ineffective liquidity management as a key characteristic of the crisis and highlighted the lack of attention that liquidity risk received relative to other risks prior to the crisis. Recognizing the key role of illiquidity in the crisis, the Basel Committee included two global minimum liquidity standards as part of the recently announced Basel III supervisory framework to be implemented over the next seven years. Notably, regulators in a number of Asian economies have had prudential liquidity standards in place for many years. This Asia Focus report defines liquidity and liquidity risk, examines some common prudential liquidity standards in key Asian economies, and briefly considers the potential impact of the proposed Basel III standards on global liquidity risk management.Liquidity (Economics) - Asia ; Bank supervision
Banking reform in Vietnam
Vietnam’s banking sector is expected to have one of the highest growth rates in Asia during the next few years due to the country’s continued economic expansion, rising household incomes, and relatively low penetration of existing banking services. Over the past two decades, the Vietnamese government has undertaken a series of reforms to strengthen and modernize the sector as part of the country’s move towards a more open and marketoriented economy. Many of these reforms have also been motivated by Vietnam’s growing participation in international agreements and ongoing efforts to adopt international standards such as the Basel capital framework. Key reforms include a restructuring of the banking system, a gradual opening to foreign investment, the partial privatization of state-owned banking institutions, and measures to strengthen the capitalization of Vietnamese banks. This Asia Focus report provides an overview of Vietnam’s banking sector, reviews significant developments since the mid 1980s, and highlights key challenges to reform implementation.Banks and banking - Vietnam
An O(n^5) algorithm for MFE prediction of kissing hairpins and 4-chains in nucleic acids
Efficient methods for prediction of minimum free energy (MFE) nucleic secondary structures are widely used, both to better understand structure and function of biological RNAs and to design novel nano-structures. Here, we present a new algorithm for MFE secondary structure prediction, which significantly expands the class of structures that can be handled in O(n^5) time. Our algorithm can handle H-type pseudoknotted structures, kissing hairpins, and chains of four overlapping stems, as well as nested substructures of these types
The organisational lifecycle of a family business and the crafting of its business strategy over time – A Malaysian case study
The role of family social, human and financial capital in family business sustainability - A Malaysian case study
This paper aims to explore the nature of family capital in the form of family social, human and financial capital in the family business. It looks at the contribution of these three forms of family capital as inputs into the business over the stages of the business life-cycle and how they operate to build and sustain the business in that time

Dust continuum and Polarization from Envelope to Cores in Star Formation: A Case Study in the W51 North region
We present the first high-angular resolution (up to 0.7", ~5000 AU)
polarization and thermal dust continuum images toward the massive star-forming
region W51 North. The observations were carried out with the Submillimeter
Array (SMA) in both the subcompact (SMA-SubC) and extended (SMA-Ext)
configurations at a wavelength of 870 micron. W51 North is resolved into four
cores (SMA1 to SMA4) in the 870 micron continuum image. The associated dust
polarization exhibits more complex structures than seen at lower angular
resolution. We analyze the inferred morphologies of the plane-of-sky magnetic
field (B_bot) in the SMA1 to SMA4 cores and in the envelope using the SMA-Ext
and SMA-SubC data. These results are compared with the B_bot archive images
obtained from the CSO and JCMT. A correlation between dust intensity gradient
position angles (phi_{nabla I}) and magnetic field position angles (phi_B) is
found in the CSO, JCMT and both SMA data sets. This correlation is further
analyzed quantitatively. A systematically tighter correlation between
phi_{nabla I} and phi_B is found in the cores, whereas the correlation
decreases in outside-core regions. Magnetic field-to-gravity force ratio
(Sigma_B) maps are derived using the newly developed polarization - intensity
gradient method by Koch, Tang & Ho 2012. We find that the force ratios tend to
be small (Sigma_B <= 0.5) in the cores in all 4 data sets. In regions outside
of the cores, the ratios increase or the field is even dominating gravity
(Sigma_B > 1). This possibly provides a physical explanation of the tightening
correlation between phi_{nabla I} and phi_B in the cores: the more the B field
lines are dragged and aligned by gravity, the tighter the correlation is.
Finally, we propose a schematic scenario for the magnetic field in W51 North to
interpret the four polarization observations at different physical scales.Comment: Accepted for publication in ApJ. 10 pages. 7 figure
IFU observations of luminous type II AGN - I. Evidence for ubiquitous winds
We present observations of 17 luminous (log(L[O III]/L_Sun) > 8.7) local (z <
0.11) type II AGN. Our aim is to investigate the prevalence and nature of AGN
driven outflows in these galaxies by combining kinematic and ionization
diagnostic information. We use non-parametric methods (e.g. W80, the width
containing 80% of the line flux) to assess the line widths in the central
regions of our targets. The maximum values of W80 in each galaxy are in the
range 400 - 1600 km/s, with a mean of 790 +- 90 km/s. Such high velocities are
strongly suggestive that these AGN are driving ionized outflows. Multi-Gaussian
fitting is used to decompose the velocity structure in our galaxies. 14/17 of
our targets require 3 separate kinematic components in the ionized gas in their
central regions. The broadest components of these fits have FWHM = 530 - 2520
km/s, with a mean value of 920 +- 50 km/s. By simultaneously fitting both the
H{\beta}/[O III] and H{\alpha}/[N II] complexes we construct ionization
diagnostic diagrams for each component. 13/17 of our galaxies show a
significant (> 95 %) correlation between the [N II]/H{\alpha} ratio and the
velocity dispersion of the gas. Such a correlation is the natural consequence
of a contribution to the ionization from shock excitation and we argue that
this demonstrates that the outflows from these AGN are directly impacting the
surrounding ISM within the galaxies.Comment: 37 pages, 30 figures. Accepted for publication in MNRA
The circumstellar disk of AB Aurigae: evidence for envelope accretion at late stages of star formation?
The circumstellar disk of AB Aurigae has garnered strong attention owing to
the apparent existence of spirals at a relatively young stage and also the
asymmetric disk traced in thermal dust emission. However, the physical
conditions of the spirals are still not well understood. The origin of the
asymmetric thermal emission is unclear.
We observed the disk at 230 GHz (1.3 mm) in both the continuum and the
spectral line ^12CO J=2-1 with IRAM 30-m, the Plateau de Bure interferometer,
and the Submillimeter Array to sample all spatial scales from 0.37" to about
50". To combine the data obtained from these telescopes, several methods and
calibration issues were checked and discussed.
The 1.3 mm continuum (dust) emission is resolved into inner disk and outer
ring. Molecular gas at high velocities traced by the CO line is detected next
to the stellar location. The inclination angle of the disk is found to decrease
toward the center. On a larger scale, based on the intensity weighted
dispersion and the integrated intensity map of ^12CO J=2-1, four spirals are
identified, where two of them are also detected in the near infrared. The total
gas mass of the 4 spirals (M_spiral) is 10^-7 < M_spiral < 10^-5 M_sun, which
is 3 orders of magnitude smaller than the mass of the gas ring. Surprisingly,
the CO gas inside the spiral is apparently counter-rotating with respect to the
CO disk, and it only exhibits small radial motion.
The wide gap, the warped disk, and the asymmetric dust ring suggest that
there is an undetected companion with a mass of 0.03 M_sun at a radius of 45
AU. Although an hypothetical fly-by cannot be ruled out, the most likely
explanation of the AB Aurigae system may be inhomogeneous accretion well above
or below the main disk plane from the remnant envelope, which can explain both
the rotation and large-scale motions detected with the 30-m image.Comment: 17 pages, 13 figures, accepted for publication in A&A journal. Typos
