Relationship between Volatility of Economics Variables and Economics Growth

Economic growth of an economy is defined as the steady state path through which the productivity of an economy is improved and increases the levels of national output and income. The government consumption expenditures and investment play a key role in the process of investigating the macroeconomic performance of an economy and determinants of economic growth. The countries which grow quickly, invest a substantial fraction of their GDP for consumption expenditures as well for the sources which encourage private investment. The objective of this study to calculate the volatility in economics growth in Pakistan. The annual time series data are used from 1975 to 2014 from WDI, Economics survey of Pakistan and Hand Book of Statistics. GARCH model has been used to measure volatility of all variables. The empirical results of the study confirmed that the volatility of the different variables (volatility of inflation, volatility of interest rate, volatility of political instability, volatility of GDP, and volatility of foreign direct investment) significant affect the government consumption expenditures and private investment in the economy of Pakistan. The study analyzed data by using the autoregressive distributive lag model which is mainly used in time series data Econometrics to estimate the non-stationary models with mix order of integration. The estimated results of the study evaluated that volatility of the inflation lead to uncertainty which is also suggested by the Able (1980) and negatively affect the economy consumption expenditures as well as private investment in the economy of Pakistan. Because uncertainty directly affects the cost of capital as well as reduce private investor confidence

Elucidation of physico-chemical characteristics and mycoflora of bovine milk available in selected area of Karachi, Pakistan.

ISO 14000 has opened the field for enhancing the awareness towards healthy environment and gives the ideology of regular assessment of threshold values not only of nutrients but contaminants as well. Under this statement microbiological studies in terms of mycoflora followed by physical characteristics and level of some essential elements Mg, Fe, Cu and Zn, and deleterious metal Cd were analyzed in fresh milk samples (FMS) and tetra pack milk or UHT processed milk samples (PMS) available in Gulshan-e-Iqbal Town, Karachi for the residents. Samples were collected in the morning time during winter season. Physical parameters like pH, conductivity, density, viscosity, surface tension and refractive index were observed very soon after sample collection. Percentage of ash and total dissolved solids (TDS) were also measured. For fungal flora studies PDA (Potato Dextrose Agar) and Sabourouds Agar were used for the fungal growth. The concentrations of metals considered were estimated after wet digestion of samples using atomic absorption spectroscopy. The ranges of average concentration of Mg, Fe, Cu and Zn were found to be 77.120 \u2013 141.915mg/l, 0.580 \u2013 7.320mg/l, 0.004 \u2013 0.070mg/l and 2.574 \u2013 4.872mg/l. The level of Cd was estimated in the samples between 0.0050 \u2013 0.053mg/l, but was not observed in most of the samples. Among the fungi, the highest diversity was that of Aspergillus spp. that produces aflatoxins. \ua9JASE

Documenting response to COVID-individual and systems successes and challenges: A longitudinal qualitative study

Background: This study aimed to document the evolution of perceptions of frontline healthcare workers (FHCW) regarding their well-being and the quality of health systems\u27 response to the COVID-19 pandemic over four months in Pakistan.Methods: We conducted this prospective longitudinal qualitative study during the four months (June-September 2020) coinciding with the peak and trough of the first wave of Pakistan\u27s COVID-19 pandemic. We approached frontline healthcare workers (physicians and nurses) working in emergency departments (ED) in two hospitals using the WhatsApp group of the Pakistan Society of Emergency Physicians (PSEM). Participants were asked to self-record their perception of their wellness and their level of satisfaction with the quality of their hospitals\u27 response to the pandemic. We transcribed, translated, and analysed manually using MAXQDA 2020 software and conducted the thematic analysis to identify themes and sub-themes.Results: We invited approximately 200 FHCWs associated with PSEM to participate in the study. Of the 61 who agreed to participate, 27 completed the study. A total of 149 audio recordings were received and transcribed. Three themes and eight sub-themes have emerged from the data. The themes were individual-level challenges, health system-level challenges, and hope for the future. Sub-themes for individual-level challenges were: fear of getting or transmitting infection, feeling demotivated and unappreciated, disappointment due to people\u27s lack of compliance with COVID-19 protocols, physical exhaustion, and fatigue. For the healthcare system, sub-themes were: Infrastructure, logistics, management, and communications response of the hospital/healthcare system and financial stressors. For sub-themes under hope for the future were the improved disease knowledge and vaccine development. The overall perceptions and experiences of FHCWs evolved from fear, grief, and negativity to hope and positivity as the curve of COVID-19 went down.Conclusion: This study shows that the individuals and systems were not prepared to deal with the challenges of the COVID-19 pandemic. The findings highlight the challenges faced by individuals and health systems during the wake of the Covid-19 pandemic. The healthcare workers were emotionally and physically taxed, while the health systems were overwhelmed by COVID-19. The overall perceptions of FHCWs evolved with time and became negative to positive as the curve of COVID-19 went down during the first wave of COVID-19 in Pakistan
