Foreign Direct Investment in Manufacturing Sector in Malaysia

This paper analyses the determinants of foreign direct investment (FDI) in the manufacturing sector in Malaysia from eleven countries during the period 1988 to 2000. The empirical results indicate that gross domestic product, lending interest rate, labour productivity, exports to home country and imports from home country significantly influenced the level of FDI inflows into Malaysia. However, exchange rate, exchange rate variation, wage and openness index were not important in influencing FDI.foreign direct investment, manufacturing sector, International Relations/Trade,

Minimal Position-Velocity Uncertainty Wave Packets in Relativistic and Non-relativistic Quantum Mechanics

We consider wave packets of free particles with a general energy-momentum dispersion relation $E(p)$. The spreading of the wave packet is determined by the velocity v = \p_p E. The position-velocity uncertainty relation $\Delta x \Delta v \geq {1/2} ||$ is saturated by minimal uncertainty wave packets $\Phi(p) = A \exp(- \alpha E(p) + \beta p)$. In addition to the standard minimal Gaussian wave packets corresponding to the non-relativistic dispersion relation $E(p) = p^2/2m$, analytic calculations are presented for the spreading of wave packets with minimal position-velocity uncertainty product for the lattice dispersion relation $E(p) = - \cos(p a)/m a^2$ as well as for the relativistic dispersion relation $E(p) = \sqrt{p^2 + m^2}$. The boost properties of moving relativistic wave packets as well as the propagation of wave packets in an expanding Universe are also discussed

Polygenic risk score-based phenome-wide association study identifies novel associations for Tourette syndrome

Tourette Syndrome (TS) is a complex neurodevelopmental disorder characterized by vocal and motor tics lasting more than a year. It is highly polygenic in nature with both rare and common previously associated variants. Epidemiological studies have shown TS to be correlated with other phenotypes, but large-scale phenome wide analyses in biobank level data have not been performed to date. In this study, we used the summary statistics from the latest meta-analysis of TS to calculate the polygenic risk score (PRS) of individuals in the UK Biobank data and applied a Phenome Wide Association Study (PheWAS) approach to determine the association of disease risk with a wide range of phenotypes. A total of 57 traits were found to be significantly associated with TS polygenic risk, including multiple psychosocial factors and mental health conditions such as anxiety disorder and depression. Additional associations were observed with complex non-psychiatric disorders such as Type 2 diabetes, heart palpitations, and respiratory conditions. Cross-disorder comparisons of phenotypic associations with genetic risk for other childhood-onset disorders (e.g.: attention deficit hyperactivity disorder [ADHD], autism spectrum disorder [ASD], and obsessive-compulsive disorder [OCD]) indicated an overlap in associations between TS and these disorders. ADHD and ASD had a similar direction of effect with TS while OCD had an opposite direction of effect for all traits except mental health factors. Sex-specific PheWAS analysis identified differences in the associations with TS genetic risk between males and females. Type 2 diabetes and heart palpitations were significantly associated with TS risk in males but not in females, whereas diseases of the respiratory system were associated with TS risk in females but not in males. This analysis provides further evidence of shared genetic and phenotypic architecture of different complex disorders

Differences between pharmacists’ perception of counseling and practice in the era of prescription drug misuse

Objective: This study was conducted to assess pharmacists\u27 practices when counseling patients on their prescription medications, and their preferences for training. Methods: Five focus group discussions of community pharmacists (n=45, with seven to eleven participants in each group) were conducted in a major metropolitan city in the southern United States. Participants were recruited via email using a list of community pharmacists provided by the Texas State Board of Pharmacy. All focus group discussions were structured using a moderator guide consisting of both discrete and open-ended questions. Qualitative analysis software was used to analyze the data with a thematic analysis approach. Results: The participants in this study had a high self-efficacy regarding their ability to counsel on both new and opioid prescriptions. Many pharmacists experienced the same barriers to counseling and agreed on the components of counseling. However, the themes that emerged showed that the participants exhibited only a partial understanding of the components of counseling. The themes that emerged in the thematic analysis were perceived confidence and discordant counseling practices, inadequate infrastructure, lack of comprehensive counseling, inconsistent use of the Prescription Drug Monitoring Program (PDMP), and pharmacists\u27 desired training/assistance. Conclusions: Community pharmacists are in a unique position to help combat the opioid crisis; however, there has been very little research on the pharmacist-patient interaction in this context. With policy changes, such as the PDMP mandate, going into effect across the country, it is important to capitalize on the potential community pharmacists have in ameliorating the opioid crisis in the United States

Modeling atmospheric effects of the September 1859 Solar Flare

We have modeled atmospheric effects, especially ozone depletion, due to a solar proton event which probably accompanied the extreme magnetic storm of 1-2 September 1859. We use an inferred proton fluence for this event as estimated from nitrate levels in Greenland ice cores. We present results showing production of odd nitrogen compounds and their impact on ozone. We also compute rainout of nitrate in our model and compare to values from ice core data.Comment: Revised version including improved figures; Accepted for publication in Geophys. Res.
