Pre-entry Decisions and New Venture Survival in China

This research paper applies the Resource Based View (RBV) to investigate the impacts of pre-entry decisions made by foreign investors on the survivability of new Foreign Invested Enterprises (FIEs) in China. Using a sample of 4,764 new ventures with the Cox survival model, we found that factors including the CATA (Current Assets to Total Assets) ratio, firm size, and technology status of the industries are positively related to new venture survival, and that factors like the inland area dummy variable are negatively related to new venture survival. The result for having a state-owned firm as a partner is not significant in our study. By identifying the key factors mentioned above as unique resources for FIEs, based on the RBV, the results of our research have the potential to help foreign investors to improve their firms? chances of success before they establish their new ventures in the Chinese market

Spatial Determinants of Import Traffic Distribution At Port Harcourt (Nigeria)

ABSTRACT This paper highlights the result of a study carried out to examine the Geographic determinants of import traffic distribution at the Port Harcourt Port. A substantial aspect of the study involved building a regression model to estimate import distribution from the Port. The import function was specified in log-linear form. The adequacy of the model was then testedthis, involved statistical experiments to obtain the R-squared, as well as t and f values. Further test on the adequacy of the nwdel was conducted through diagnostic exercises designed to check for inulticollinedrity and heteroscedasticity, in the data used. Results obtained show that road distance and manufacturing industries are significant Geographic determinants of import Cargo distribution at the study Port. It is therefore important to lake the two variables into account in any policy or planning exercise at Port Harcourt Port

The unreasonable effectiveness of equilibrium-like theory for interpreting non-equilibrium experiments

There has been great interest in applying the results of statistical mechanics to single molecule experiements. Recent work has highlighted so-called non-equilibrium work-energy relations and Fluctuation Theorems which take on an equilibrium-like (time independent) form. Here I give a very simple heuristic example where an equilibrium result (the barometric law for colloidal particles) arises from theory describing the {\em thermodynamically} non-equilibrium phenomenon of a single colloidal particle falling through solution due to gravity. This simple result arises from the fact that the particle, even while falling, is in {\em mechanical} equilibrium (gravitational force equal the viscous drag force) at every instant. The results are generalized by appeal to the central limit theorem. The resulting time independent equations that hold for thermodynamically non-equilibrium (and even non-stationary) processes offer great possibilities for rapid determination of thermodynamic parameters from single molecule experiments.Comment: 6 page

Miller–Urey spark-discharge experiments in the deuterium world

We designed and conducted a series of primordial-soup Miller-Urey style experiments with deuterated gases and reagents to compare the spark-discharge products of a “deuterated world” with the standard reaction in the “hydrogenated world”. While the deuteration of the system has little effect on the distribution of amino acid products, significant differences are seen in other regions of the product-space. Not only do we observe about 120 new species, we also see significant differences in their distribution if the two hydrogen isotope worlds are compared. Several isotopologue matches can be identified in both, but a large proportion of products have no equivalent in the corresponding isotope world with ca. 43 new species in the D world and ca. 39 new species in the H world. This shows that isotopic exchange (the addition of only one neutron) may lead to significant additional complexity in chemical space under otherwise identical reaction conditions

Vitamin B12 and Folate deficiency in Megaloblastic Anaemia diagnosed morphologically at the University Teaching Hospital, Lusaka, Zambia

Vitamin B12 and folate deficiency a well-known health problem world-wide.Background: Vitamin B12 and folate deficiency is a well-known health problem world-wide. Deficiencies of folic acid and vitamin B12 are known to cause megaloblastic anaemia, which is characterised by presence of abnormally large erythrocyte precursor cells, megaloblasts, in the bone marrow and macrocytic red cells in the peripheral blood. These megaloblasts arise because of impaired deoxyribonucleic acid (DNA) synthesis followed by ineffective erythropoiesis. However, vitamin B12 or folate levels have not been described in Zambia, whether normal levels or in relation to anaemia. The study aimed to determine vitamin B12 and folate levels in megaloblastic anaemia, diagnosed morphologically, in patients at the University Teaching. Methods: This was a cross sectional study which was undertaken at the University Teaching Hospital (UTH) in Lusaka, Zambia. Full blood count (FBC), Peripheral smears and ELISA were assessed on blood samples received from megaloblastic anaemia and non-anaemic patients. Vitamin B12 and folate concentrations were compared between groups using t-test. Results: The age range was between 18 – 54 years (Mean age-31 years). Among the 40 megaloblastic patients, 35% (14/40) were male and 65% (26/40) were female with a male to female ratio of 1:1.9. Full blood count and peripheral smear findings revealed that bicytopenia was present in 22.5% (9/40) and pancytopenia in 72.5% (29/40) patients. Furthermore, the megaloblastic anaemia participants had statistically significant lower median vitamin B12 concentration 175(150-333) pg/ml than non-anaemic control participants 299.5 (238-571) pg/ml p=0.0001. Megaloblastic anaemia participants also had a statistically significant lower folate concentration (12.32± 2.28 ng/ml) than non-anaemic control participants (19.28 ± 2.84 ng/ml) p=0.029. Of the megaloblastic anaemia patients, vitamin B12 deficiency was in 60% (24/40), pure folate deficiency in 30% (12/40) and combined deficiency was observed in 15% (6/40) patients. Conclusion: This study shows that majority of patients with megaloblastic anaemia, diagnosed morphologically at the University Teaching Hospital have a deficiency of vitamin B12 deficiency which further implicates vitamin B12 and folate in the disease process of megaloblastic anaemia.Office of the Global AIDS/US Department of stat

Discovery of the actinium, thorium, protactinium, and uranium isotopes

Currently, 31 actinium, 31 thorium, 28 protactinium, and 23 uranium isotopes have so far been observed; the discovery of these isotopes is discussed. For each isotope a brief summary of the first refereed publication, including the production and identification method, is presented.Comment: Accepted for publication in Atomic Data Nuclear Data Table
