Letter, Prince Albert Ansah, Coomassie, Gold Coast, West Africa, to American Boy Scout Friend, 1915
No full textThe Boy Scouts organization was founded in 1908 in England by Robert Baden-Powell, soon became popular around the world. Troops were founded in Britain, America and, and as this letter shows, the Gold Coast of Africa, then a British colony, and now the nation of Ghana. This letter, which may have been part of an international pen-pal program, covers scouting topics like hiking and camping, but also dips into the political arena. The author asks, at the end, �Please how do you think of the war which is so terrible and rageous? Is there nobody in your country who is going to cease them?� This item was included in the Scrawl and Order exhibit, http://lib.msstate.edu/exhibits/past/.https://scholarsjunction.msstate.edu/mss-herring-collection/1017/thumbnail.jp
China's National Image: the Analysis of Chinese Tourists on New Media in Thailand
No full textThis article comparatively analyzes the images of Chinese tourists on the news websites of Bangkok Post (E-Newspaper) and Channel 7 (E- media), to examine the tone of images of Chinese tourists on the websites of selected mainstream media in Thailand. The results showed a variety of discovery data of Chinese tourists' images happening in Thailand. When studying the national image of each country, it is regarded as a normal problem that the result came out both in a positive and negative way. Through the content analysis approach, this article reveals the basic framework of Chinese tourist behavior within and outside the national image, highlights the close relationship between tourism and national image-building. According to the findings, the frequent keywords that were mostly used and often appeared in news are negative words. The media agenda presented highly in Bangkok Post and Channel7 was the social agenda. Also, the political news received the lowest coverage in both Bangkok Post and Channel7 in regard to the chosen timeframe for the study. Overall, the social agenda was the most presented media agenda in both Bangkok Post and Channel7 To cite this article (7th APA style):Tuzov, V., Ansah, P. O. and Boonanant, C. (2020).

Investigations into Ghana's Macroeconomics Relationship between Inflation and Unemployment. Quantitative Analysis Based on Time Series in the Years 1990-2014
No full textIndicators of a country's economic well-being include the unemployment rate and inflation rates. The empirical relationship between inflation and unemployment in Ghana's economy is explained and analyzed in this paper. It appears that the most hotly debated statistics in Ghana are the rate of inflation and the rate of unemployment, yet there is lack of knowledge about the connection between unemployment and inflation, it is imperative that we gain this understanding. In addition, the tax rate, compensation for employees, participation in the labor force, and enrolment in tertiary education are all indicators of unemployment. A quantitative framework is used to explain the empirical relationship between inflation and unemployment in Ghana and determine the sensitivity of unemployment to changing inflation levels using co-integration regression, causality, correlation, and sensitivity analyses. The Augmented Dickey-Fuller test of stationarity was adopted, after which the Granger causality method was used to determine causation between inflation and unemployment The study relied on World Bank data from 1990 to 2014 and found a strong correlation between unemployment and inflation in the Ghanaian economy which is also consistent with Haug and King (2011), whereas Onwioduokit (2006) found a negative correlation. The model's variables are stationary, and the findings of the causality test point to a link between Ghana's high unemployment rate and its high inflation rate. The unemployment will rise by 3.2795 percent if inflation rises by 1 percent. I therefore recommend that the Ghanaian economy maintain a low and stable inflation rate in order to reduce unemployment, equivocally, thanks to the findings of this research. There is evidence to suggest that inflation has a long-term positive impact on and is a direct cause of unemployment in Ghana, so policymakers and the government should put more effort into keeping inflation low in order to address this problem. Since inflation levels can be used to measure unemployment levels to some extent and the R-squared is significantly low in the regression result, the measurement of inflation should be done more accurately to avoid errors. Ghana's Statistical Service must devote more resources to ensuring that the CPI basket includes only relevant items and should be given the appropriate weights. Real-world impact should be reported in relation to other indicators or factors to make it more comprehensible. For example, an increase in unemployment of z percentage points could be explained by an increase in the price of an item purchased on the market rising by y percentage points. Finally, the researcher recommends that other economic indicators, such as employee compensation, tax rate, labor force participation rate, and tertiary school enrollment, be taken into consideration as potential indicators of unemployment in African economies
International Debts and Implications on Ghana's GDP Growth. Annual time series data (1980-2014)
No full textDevelopment projects are at the heart of government borrowing, with the goal of transforming the economy. However, excessive borrowing has resulted in a massive debt for Ghana. As a result, this research aims to examine, using annual time series data, the trends and effects of Ghana's external debt and service on GDP growth from 1980 to 2014. Aside from GDP, the variables that were analyzed included gross domestic investment, population, foreign direct investment, openness to trade, and the ratios of external debt to GDP and the percentage of GDP used to service that debt. Exogenous Solow growth models were used to examine the effects of external debt burden on GDP growth separately from those of the standard Solow growth model. Two different models are being used, one to look at what is causing an increase in the country's external debt and how that will affect GDP, and the other to look at how servicing that debt will affect GDP growth. OLS estimation method was used, backed by Bruesch-Godfrey test, Koenker-Basset (KB) test statistics, Cobb Douglass estimation function, and STATA statistical package (version 2012) for the regression analysis. Tests for autocorrelation and heteroscedasticity were passed by the models. For both models, the R2 value and F-statistic (Prob>F 0.000 is less than 0.05) indicate that the independent variables account for approximately 99.51 percent of the GDP variation. For the sake of comparison, we can see that all but one parameter in both models is statistically significant (the population coefficient in the second model). According to Simon (1987), Todaro and Smith (1990), and others, GDP and population (POP) have a positive and significant relationship, as do gross domestic investment (INV) (2012). Foreign direct investment (FDI), the external debt ratio (EXD), and the debt service on the country's external debt are all positive, as predicted a priori; however, all four of these variables are negative. Despite this, the coefficient of external debt to GDP is higher than the coefficient of debt service on external debt. An increase in external debt of 1 percent of GDP results in a 0.2285 percent reduction in GDP, whereas an increase in external debt servicing costs results in a 0.069669 percent reduction in GDP. This means that Ghana's external debt should be constantly monitored by the government, and debt should not be allowed to exceed a maximum limit in order to avoid overhanging debt. The government must properly monitor funds to ensure that they are used only for the intended purpose. As a second step, the government of Ghana should concentrate on other strategic economic areas. Because of their high multiplier effect, investments in infrastructure, agriculture, and other sectors should be prioritized. As a result, the total amount of debt owed will be reduced. Finally, Ghana's economy can't solely rely on its external, or foreign, debts, which are always a drag on growth. To determine whether or not they need additional financing, the government should compare their economy's health to fiscal discipline, which governs fiscal policy
Preliminary assessment of hydrophobic-hydrophilic separation for pre-concentration of ree from coal tailings and alike material
No full textAll over the world, the primary economic deposits of rare earths are being exhausted. Finding new sources and methods for the concentration, coupled with a cost-effective extraction of rare earth elements (REEs) is imperative. Alternate and innovative strategies for the extraction and concentration of minerals are being developed continuously. Out of the many physical concentration processes available, the hydrophobic hydrophilic separation (HHS) process has yielded the best result for the pre-concentration of rare earth minerals (REMs).
This study explores the possibility of using HHS as a novel process used to physically concentrate REMs of US coals (from 300 ppm to 2 % on ash basis) on BC coals. First, a set of three samples (roof, floor, and parting) were carefully chosen based on the outcome of their correlation coefficient from a study conducted in 2021 to characterize BC coals. A tailings sample (CT) from the plant was also selected to study in this thesis. The results on the roof, floor, and parting showed little to no concentration of REEs. Further investigations were carried out on the CT as most of the roof, floor, and partings would eventually end up as tailings due to processing at the coal preparation plant.
The HHS process was affected by pH levels ranging from 7.5 to 9.5, and the results revealed a slight improvement in the final concentrate grade. An increase in collector dosage showed a direct correlation with the increase in concentrate grade, calculated on an ash basis. The reduction of the particle size (P80) of the tailings sample from 20 microns to 8.5 microns also resulted in an increase in the final concentrate grade. The mineralogical examination found that the rare-earth-bearing minerals were monazite, xenotime, and some smaller traces of REEs encapsulated in zircon. The majority of the sample was predominantly composed of quartz and illite/muscovite with minor traces of kaolinite and carbonates with slight traces of monazite and xenotime minerals.Applied Science, Faculty ofMining Engineering, Keevil Institute ofGraduat
Long-term immunity against yellow fever in children vaccinated during infancy: a longitudinal cohort study
No full textThe data represent the concentrations of specific neutralizing antibodies following infant immunization against yellow fever. We used a microneutralization assay to measure protective antibodies against yellow fever virus in 587 Malian and 436 Ghanaian children vaccinated around age 9 months, and followed for 4.5 years (Mali), or 2.5 and 6 years (Ghana). We standardized antibody concentrations with reference to the yellow fever WHO International Standard.
The serum samples used in this study, and the sample metadata included in the present dataset originate from trials of the meningococcal group A conjugate vaccine, MenAfriVac, namely the PsATT-004 (phase II) and Pers-004 (phase IV) studies in Ghana, and the PsATT-007 (phase III) and Pers-007 (phase IV) studies in Mali (clinical trial registry numbers ISRCTN82484612, ISRCTN10763234, PACTR201110000328305, and ISRCTN37623829). MenAfriVac was developed by PATH and Serum Institute India Pvt. Ltd. (SIIPL).
This dataset consists of three files:
1. Ghana group data | Tab-delimited text file: Yellow_fever_nAb_Ghana.csv
2. Mali group data | Tab-delimited text file: Yellow_fever_nAb_Mali.csv
3. Data dictionary | PDF file: Yellow_fever_nAb_Data_Dictionary.pd
R code for independent- and paired-samples permutation tests
No full textThe R script in this upload implements permutation tests to compare two sets of antibody concentrations or titres. Two types of tests are provided: independent-samples tests on the difference or the log-ratio of geometric mean concentrations, and a sign-test for paired samples. All the tests output two-tailed p-values. The function can be tested on the simulated data provided in the accompanying pseudodata.RData file.
The earlier version (1.0.0) of the code was intended as a supplement to the manuscript Long-term immunity against yellow fever in children vaccinated during infancy: a longitudinal cohort study by Domingo and coll., to be published in The Lancet Infectious Diseases on 20 September 2019. The main impulse for this update was to tidy up the R code and make it safer to use by others by including checks on the function arguments, but it ended up as a thorough rewriting of the original code.
