Investment in ICT in Developing Countries: the effect of FDI: Evidences from Sultanate of Oman

Foreign direct investment (FDI) is a crucial tool developing the economy of any country if it is employed in a proper manner. Moreover, foreign direct investment has many effects; and one of them is thriving the information and communication technology (ICT) sector as a pivotal sector which includes four sub-sectors according to the World Bank (ICT Service Exports, ICT Goods Imports, High-Technology Exports and ICT Goods Exports). Hence, the aim of this paper is to identify the influence of foreign direct investment in thriving the sub-sectors of information and communication technology, as one of the drivers to develop the economy. To accomplish this purpose the statistical data on direct foreign investment and exports and imports of information and communication technology about Sultanate of Oman were collected from 2000-2014 published by the World Bank. descriptive statistics and Simple regression model were used to analyze the collected data and test the hypotheses of the study. The findings show that the planning for foreign direct investment is ad-hoc, therefore there should be a obvious view of how to exploit foreign direct investment in economy development, especially in transferring of information and communication technology. The paper contributed to the literature by being the first study that attempted to interpret the role of foreign direct investment  on exports and imports of information and communication technology in Sultanate of Oman.  Keywords: Foreign direct investment (FDI), ICT, High-Technology Exports, ICT Goods, ICT Service Exports, ICT Goods Imports, Oman.

Comparison of Very Low Energy Diet Products Available in Australia and How to Tailor Them to Optimise Protein Content for Younger and Older Adult Men and Women

Very low energy diets (VLED) are efficacious in inducing rapid weight loss but may not contain adequate macronutrients or micronutrients for individuals with varying nutritional requirements. Adequate protein intake during weight loss appears particularly important to help preserve fat free mass and control appetite, and low energy and carbohydrate content also contributes to appetite control. Therefore, the purpose of this study was to compare the nutritional content (with a focus on protein), nutritional adequacy and cost of all commercially-available VLED brands in Australia. Nutritional content and cost were extracted and compared between brands and to the Recommended Dietary Intake (RDI) or adequate intake (AI) of macronutrients and micronutrients for men and women aged 19–70 years or >70 years. There was wide variability in the nutritional content, nutritional adequacy and cost of VLED brands. Most notably, even brands with the highest daily protein content, based on consuming three products/day (KicStart™ and Optislim®, ~60 g/day), only met estimated protein requirements of the smallest and youngest women for whom a VLED would be indicated. Considering multiple options to optimise protein content, we propose that adding pure powdered protein is the most suitable option because it minimizes additional energy, carbohydrate and cost of VLEDs

Vitamin B12 in Health and Disease

Vitamin B12 is essential for DNA synthesis and for cellular energy production.This review aims to outline the metabolism of vitamin B12, and to evaluate the causes and consequences of sub-clinical vitamin B12 deficiency. Vitamin B12 deficiency is common, mainly due to limited dietary intake of animal foods or malabsorption of the vitamin. Vegetarians are at risk of vitamin B12 deficiency as are other groups with low intakes of animal foods or those with restrictive dietary patterns. Malabsorption of vitamin B12 is most commonly seen in the elderly, secondary to gastric achlorhydria. The symptoms of sub-clinical deficiency are subtle and often not recognized. The long-term consequences of sub-clinical deficiency are not fully known but may include adverse effects on pregnancy outcomes, vascular, cognitive, bone and eye health

Challenges and Opportunities in Scaling-Up Nutrition in Healthcare

Healthcare continues to be in a state of flux; conventionally, this provides opportunities and challenges. The opportunities include technological breakthroughs, improved economies and increasing availability of healthcare. On the other hand, economic disparities are increasing and leading to differing accessibility to healthcare, including within affluent countries. Nutrition has received an increase in attention and resources in recent decades, a lot of it stimulated by the rise in obesity, type 2 diabetes mellitus and hypertension. An increase in ageing populations also has meant increased interest in nutrition-related chronic diseases. In many middle-income countries, there has been an increase in the double burden of malnutrition with undernourished children and overweight/obese parents and adolescents. In low-income countries, an increased evidence base has allowed scaling-up of interventions to address under-nutrition, both nutrition-specific and nutrition-sensitive interventions. Immediate barriers (institutional, structural and biological) and longer-term barriers (staffing shortages where most needed and environmental impacts on health) are discussed. Significant barriers remain for the near universal access to healthcare, especially for those who are socio-economically disadvantaged, geographically isolated, living in war zones or where environmental damage has taken place. However, these barriers are increasingly being recognized, and efforts are being made to address them. The paper aims to take a broad view that identifies and then comments on the many social, political and scientific factors affecting the achievement of improved nutrition through healthcare

Prevalence and correlates of dieting in college women : a cross sectional study

Background: Dieting is a common practice among young women, irrespective of age, race, ethnicity, and weight. We aimed to determine the prevalence of dieting and its relationship with eating behavior, body weight, and body mass index (BMI) in college women. Methods: This was a cross-sectional survey of female students aged 18-35 years (n = 308). Measures included BMI, restraint, disinhibition, hunger, dieting, weight loss, and perceived weight. Results: A high percentage of college females consider themselves overweight or obese, despite having a BMI in the normal range. Dieting was practised by 43%, and 32% were avoiding weight gain, despite 78% having a healthy BMI. Women classified themselves as overweight or obese (27%), while only 11% were actually in these categories. Exercise was a common method of weight loss and positive associations were observed between dieting and BMI. Assessment of eating behavior showed that 27% were classified as high-restraint. Restraint and disinhibition were positively correlated with BMI. Conclusion: Despite the widespread availability of nutrition information, there is incongruity in measured and perceived BMI in young educated women. Dieting practices and BMI are associated with restraint and disinhibition. Nutrition professionals should consider educating college women about healthy body weight regardless of their clients' BMI.7 page(s

Zinc Status and Risk of Cardiovascular Diseases and Type 2 Diabetes Mellitus—A Systematic Review of Prospective Cohort Studies

Zinc is an essential trace element with proposed therapeutic effects in Type 2 diabetes mellitus (DM), however, the associations between zinc status and the prospective risks of cardiovascular diseases (CVD) and Type 2 DM have not been evaluated. The current systematic review aims to determine the relationships between zinc intake or plasma/serum zinc levels and prospective incidence of CVD and Type 2 DM. Fourteen papers describing prospective cohort studies were included, reporting either CVD (n = 91,708) and/or Type 2 DM (n = 334,387) outcomes. Primary analyses from four out of five studies reported no association between zinc intake and CVD events, when adjusted for multiple variables. Higher serum zinc level was associated with lower risk of CVD in three out of five studies; pronounced effects were observed in vulnerable populations, specifically those with Type 2 DM and patients referred to coronary angiography. The limited evidence available suggests no association between zinc status and Type 2 DM risk. Further investigations into the mechanisms of zinc’s action on the pathogenesis of chronic diseases and additional evidence from observational studies are required to establish a recommendation for dietary zinc in relation to the prevention of CVD and Type 2 DM

Effects of zinc on plasma lipoprotein cholesterol concentrations in humans : a meta-analysis of randomised controlled trials

Background: Studies in humans and animals suggest that zinc has the potential to affect lipoprotein metabolism and hence impact cardiovascular disease risk. Methods: A meta-analysis of controlled clinical trials was conducted to determine the effect of zinc supplementation on plasma cholesterol and triglyceride concentrations in humans. Potentially relevant studies were identified from a literature search covering the period 1980–2008 (inclusive), and additional citation searches. Results: Thirty three interventions (n = 14,238 subjects) were included in the random effects meta-analysis. No overall significant effects of zinc supplementation were observed for plasma cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol or plasma triglyceride concentrations. Plasma zinc concentrations increased significantly (+2.42 ± 0.25 μmol/L, P < 0.001; n = 14,047). Secondary analyses in individuals classified as healthy revealed that zinc supplementation is associated with a significant decrease in plasma HDL cholesterol concentrations (−0.10 ± 0.02 mmol/L, P < 0.001; n = 13,215), equivalent to a 7% decrease from baseline. Conclusion: No effect of zinc supplementation on plasma lipoproteins was detected in the overall analysis. In individuals classified as healthy, zinc supplementation is associated with a decrease in HDL cholesterol concentrations and thus contributes to an increased risk of coronary heart disease.9 page(s

Immediate effects of aerobic exercise on plasma/serum zinc levels : a meta-analysis

Background: Zinc is involved in numerous metabolic roles, including energy metabolism, immunity, and antioxidative effects. Zinc losses during exercise, in particular through sweat, are well documented. However, conflicting results have been reported for changes in circulating and tissue zinc concentration as a result of exercise. The purpose of this article is to quantify the immediate effect of aerobic exercise on plasma or serum zinc levels, in healthy participants. Methods: We conducted a systematic review of peer-reviewed articles published up to December 20, 2014, to identify studies that investigated the acute effects of exercise on selected indices of zinc status. Meta-analyses were conducted to determine the change in serum zinc concentration immediately after a bout of aerobic exercise. Results: Forty-five studies were included in the systematic literature review. Of the included studies, sufficient data were available from 34 studies (providing 46 comparisons) to quantify the change in serum zinc concentration after exercise. Serum zinc concentration was significantly higher immediately after exercise (0.45 ± 0.12 µmol·L⁻¹, P < 0.001; mean ± SE). Secondary analyses showed greater increase in serum zinc for untrained individuals and exercise sessions that involved running or maximal intensity. Insufficient data were available to determine the effects of exercise on urinary, sweat, and erythrocyte zinc. Conclusions: The present systematic review and meta-analysis indicated significant increase in serum zinc concentration immediately after an aerobic exercise session, suggesting acute perturbations in zinc homeostasis. Further research is required to ascertain the long-term effects of exercise on zinc metabolism and potential consequences for dietary zinc requirement for physically active populations.8 page(s
