Market timing is an investment technique that tries to continuously switch investment into assets forecast to have better returns. What is the likelihood of having a successful market timing strategy? With an emphasis on modeling simplicity, I calculate the feasible set of market timing portfolios using index mutual fund data for perfectly timed (by hindsight) all or nothing quarterly switching between two asset classes, US stocks and bonds over the time period 1993-2017. The historical optimal timing path ...
Considerable research has been done on the complex stock market, however, there is very little systematic work on the impact of crisis on global stock markets. For filling in these gaps, we propose a complex network method, which analyzes the effects of the 2008 global financial crisis on global main stock index from 2005 to 2010. Firstly, we construct three weighted networks. The physics-derived technique of minimum spanning tree is utilized to investigate the networks of three stages. Regional clustering ...
Substandard and falsified medical products are a public health threat, primarily associated with low- and middle-income countries. Today, the phenomenon also exists in high-income countries. Increased Internet access has opened a global market. Self-diagnosis and self-prescription have boosted the market for unregulated websites with access to falsified medicines.
The interaction between different trivalent lanthanides and a synthetic acrylate based PCE-superplasticizer (52IPEG4.5) is investigated by using a combination of laser- and synchrotron based spectroscopic techniques. Time-resolved laser fluorescence spectroscopy (TRLFS) is used to obtain thermodynamic data (stability constants (log β'(T)), reaction enthalpy (ΔH) and entropy(ΔS)) of the complexation reaction of Eu(III) and 52IPEG4.5 as a function of the temperature (20-80 °C) and ligand concentration (
We report an in silico method to predict monomers suitable for use in polymerization-induced self-assembly (PISA). By calculating the dependence of LogPoct/SA on the length of the growing polymer chain, the change in hydrophobicity during polymerization was determined. This allowed for evaluation of the capability of a monomer to polymerize to form self-assembled structures during chain extension. Using this method, we identified five new monomers for use in PISA via reversible addition-fragmentation chain ...
We detail the lessons learned, challenges, achievements, and outlook in building a chemistry research center in Vietnam. Through the principles of 'global science', we provide specific insight into the process behind establishing an internationally-competitive research program - a model that is scalable and adaptable to countries beyond Vietnam. Furthermore, we highlight the prospects for success in advancing global science education, research capacity building, and mentorship.
The global trade system can be viewed as a dynamic ecosystem in which exporters struggle for resources: the markets in which they export. We can think that the aim of an exporter is to gain the entirety of a market share (say, car imports from the United States). This is similar to the objective of an organism in its attempt to monopolize a given subset of resources in an ecosystem. In this paper, we adopt a multilayer network approach to describe this struggle. We use longitudinal, multiplex data on trade ...
BRICS, the acronym for Brazil, Russia, India, China and South Africa, is the first multilateral group created and run by non-western developed countries. The group aims to influence world geopolitics and market based on the right of developing and emerging countries to participate equitably in development. The social issue lies at the core of the group's justifications to achieve its goals. In this regard, this paper aims to analyze how the social issue has been addressed by BRICS. The methodology was based...
The objective of the current study was to determine the effects of market type (super market - SM, indoor market - IM, open market - OM) and sampling time (at the opening - T0 and 4 h after the opening - T4) on antioxidant capacity, lipid oxidation, and descriptive sensory attributes of beef in Vietnam. Values of FC and TEAC were greater in OM beef than IM and SM (P
Medication non-adherence is a worldwide problem. The aim of this study was to assess the global research output, research trends and topics that shaped medication adherence research.
This paper reports research exploring how trends in local labour market conditions during the period 2007-2011 (early stages of the 'great recession') relate to reported mental illness for individuals. It contributes to research on spatio-temporal variation in the wider determinants of health, exploring how the lifecourse of places relates to socio-geographical inequalities in health outcomes for individuals. This study also contributes to the renewed research focus on the links between labour market trends...
Rheumatic heart disease (RHD) is an avoidable disease of poverty that persists predominantly in low resource settings and among Indigenous and other high-risk populations in some high-income nations. Following a period of relative global policy inertia on RHD, recent years have seen a resurgence of research, policy and civil society activity to tackle RHD; this has culminated in growing momentum at the highest levels of global health diplomacy to definitively address this disease of disadvantage. RHD is ine...
Our current understanding of autism and other developmental disorders is primarily based on research conducted in high-income countries, predominantly in North America and Europe. Even within high-income countries, White participants are overrepresented in autism research. There is now increased recognition that a more global and diverse research representation is warranted. This paper argues that in order for global and diverse research efforts to be effective, it is essential to collaborate and engage wit...
Unlike different types of Lewis pairs as polymerization catalysts for acrylic monomers, we herein report on organometallic aluminum(III) compounds, which show a surprisingly high polymerization activity even without an additional Lewis base. DFT calculations, end group analysis and kinetic investigations clearly suggest a main group element (MGE) group transfer polymerization (GTP) mechanism analogous to the known metal-mediated GTP mechanism. The novel catalysts perform a precision polymerization of a broa...
This paper presents results of an artificial stock market and tries to make it more consistent with the statistical features of real stock data. Based on the SFI-ASM, a novel model is proposed to make agents more close to the real world. Agents are divided into four kinds in terms of different learning speeds, strategy-sizes, utility functions, and level of intelligence; and a crucial parameter has been found to ensure system stability. So, some parameters are appended to make the model which contains zero-...
To mitigate global carbon dioxide (CO) emissions in an effective manner, it is essential to identify the driving forces and estimate the reduction potential of changes to CO emissions. Using an extended logarithmic mean Divisia index (LMDI) method, this study decomposes the changes in global emissions between 1980 and 2015 with consideration of different income levels; it also reports on scenario analysis of the global emissions reduction potential up to the year 2030 to explore feasible mitigation pathways...
The global plight of stillbirths and neonatal mortality is concentrated in low- and middle-income countries. The ambitious targets introduced by the World Health Organization in the Every Newborn Action Plan demand a commitment to research that promotes equitable perinatal outcomes.
The need for increased expertise in evidence-based medicine and concerns about the decreasing numbers of physician-scientists have underscored the need for promoting and encouraging research in medical education. The critical shortage of physician-scientists has assumed a dimension demanding a coordinated global response. This systematic review examined the perceptions of medical students regarding research during undergraduate medical school from a global perspective.
Research and history have largely shown the covert billion-dollar global market of single-use medical device (SUD) reprocessing and reuse to be a safe endeavor, but awareness and perceptions of the practice both within and outside of healthcare have received limited attention.
BACKGROUND The aim of this study was to evaluate the elution of BisGMA, UDMA, TEGDMA, and HEMA monomers from flowable bulk fill composite resins with different resin matrix compositions, polymerized in 4-mm-thick layers, into 3 elution media. MATERIAL AND METHODS Three bulk-fill (SDR® (SDR), X-tra base (XB) and BEAUTIFIL-Bulk Flowable (BF)) resin-composites were tested. Cylindrical samples were immersed in 100% ethanol, 75% ethanol, and distilled water. The concentrations of the monomers were measured usin...
Lignin is a highly abundant polymer in plant cell walls that is essential for land plants' ability to stand upright and transport water. Inside plant cells, lignin monomers, called monolignols, are made from phenylalanine via a multistep pathway. In the cell wall, monomers move freely, until they encounter stationary oxidative enzymes that determine where the lignin polymer forms. However, it remains unclear how lignin monomers are trafficked from inside the cell to the cell wall. Although multiple lines of...
The purpose of this study was to quantify relationships between stuttering and labor market outcomes, determine if outcomes differ by gender, and explain the earnings difference between people who stutter and people who do not stutter.
Magnetic shielding constants for an isolated fullerene C, cucurbituril CB, and the host-guest complex C@CB were calculated as a function of separation of the monomers. Our results in the gas phase and water indicate a significant variation of the magnetic properties for all atoms of the monomers in the complex and after liberation of fullerene C from the interior of the CB cavity. The interaction between the two monomers results in a charge transfer that collaborates with a redistribution of electr...
Biocompatibility of adhesives is important since adhesives may be applied on dentin near the pulp. Accurate knowledge of the quantity of monomers reaching the pulp is important to determine potential side effects. The aim of this study was to assess the transdentinal diffusion of residual monomers from dental adhesive systems using an in-vitro pulp chamber model.
