Effect of Public Spending on Economic Growth in Kenya

This study aimed at examining the relationship between public spending and economic growth and how the composition of government expenditure affects economic growth in Kenya using time series data from 1980 to 2014. To achieve the objectives, modified Granger causality and Autoregressive Distributed Lag model (ARDL) were used. The results revealed both short term and long term causality from economic growth to government expenditure but only short run causality from government expenditure to economic growth. Based on the economic classification, the long run ARDL regression results showed development expenditure promotes economic growth while government purchases have no significant effect on GDP. Other control variables such as inflation and unemployment had negative effect on economic growth. In terms of functional classification, the regression results showed that expenditure on education and infrastructure are important drivers of economic growth. The positive effect of health expenditure was not significant.  Further, the regression results indicated that domestic savings and trade openness had significant positive effect on economic growth. Based on the empirical findings this study therefore recommends resources to be directed towards financing public infrastructure investment to improve economic performance. The study also recommends increasing resource allocation in the education sector to improve efficiency and support skills and human capital development that are important in promoting economic growth through increases in labor productivity. The study also recommends policymakers to enhance domestic resource mobilization and pursue favorable trade policies aimed at fostering robust economic growth.

Plasmid Profile Analysis of Pseudomonas aeruginosa Isolated from Wound Infections in a General Hospital in Southern Nigeria

Background/Purpose: Open wound infection is a serious problem especially with extended-spectrum beta lactamase (ESBL) producing Gram negative bacteria such as P. aeruginosa. The purpose of this research was to identify open wound infections due to Pseudomonas aeruginosa and also determine their plasmid profile.

Methods:  A total of 50 Pseudomonas aeruginosa isolates were obtained from clinical wound swabs in a secondary health care facility. Pseudomonas aeruginosa isolates were identified using Microbact 24E system kit. Pseudomonas aeruginosa were isolated and subjected to antibiotic susceptibility testing by disc diffusion method. ESBL production was detected using Double Disk Synergy Test (DDST) and CHROMagar ESBL (France). Six different antibiotic discs were used to determine the susceptibility pattern of the isolates. Plasmids were extracted using ZR plasmid Miniprep classic extraction Kit. Electrophoresis of the DNA was carried out on 0.8% w/v agarose gel.

Results: The prevalence of Pseudomonas aeruginosa was 63%. The antibiotic resistance pattern showed that Pseudomonas aeruginosa was highly resistant against cefotaxime (90%), ofloxacin (80%), ceftazidime (55%), azetronam (60%), imipenem (25%), amoxicillin clavulanic acid (35%) and amikacin (30%). Plasmid profile was carried out on 20 selected multidrug resistant isolates; those resistant to three or more classes of antibiotics. Plasmid content of the isolates were found to be 90%. All isolates that had plasmid were resistant to cefotaxim, ceftazidime, azetronam, ofloxacin and amikacin.

Conclusion: Antibiotic resistance by P. aeruginosa is increasingly high in wound infections and appears to be linked to the presence of plasmid and ESBL enzymes.

Me, Myself and Us? The Relationship between Ethnic Identity and Hope, Resilience and Family Relationships among Different Ethnic Groups

For ethnic minority populations, ethnic identity is associated with an increase in psychological well-being while also being recognized as a protective factor against discrimination and family distress. The aim of this study is to determine the association between ethnic identity and resilience, hope, social connectedness, experiences of discrimination and family relations in a diverse group of ethnicities. This study is correlational in nature and took place at Mount Royal University, located in Calgary, Alberta, Canada, between January and April 2019. We included 326 introductory psychology students ranging in age from 17 to 48 with participants identifying as White, Asian, South Asian, Mixed, Black, Latino, First Nations, Metis, Inuit, and Middle Eastern. Participants were asked to complete six questionnaires measuring ethnic identity, resilience, hope, social connectedness, experiences of discrimination and family relations. Results revealed a significant relationship between ethnic identity and hope (r = .14, p = .01). Additionally, family relationships were a significant moderator of the relationship between ethnic identity and resilience (F(1, 322) = 4.98, p < .05). Finally, White participants had a significantly weaker ethnic identity when compared to the Asian, South Asian and Black participants (Welch’s F(7,41) = 9.39, p = .001,η 2= .22). Ethnic identity is associated with higher levels of hope, while strong family relationships moderate the relationship between ethnic identity and resilience. Furthermore, individuals who identify as White have a weaker ethnic identity compared to individuals who identify as Asian, South Asian and Black. More research is required to understand ethnic identity in the White population to help bring awareness to the power and privilege associated with Whiteness and to find ways in which this awareness can help reduce systemic racism and discrimination.

Biochemical Changes in the Malnourished Rats Serum and Liver Exposed to Dietary Monosodium Glutamate

Monosodium glutamate (MSG) is a flavor enhancer. Its toxicity in a malnourished state appears not to have been fully investigated. This study was carried out to determine the effects of MSG on malnourished rats. Rats were randomly assigned into four groups of five rats/group. Group 1 rats were fed with malnourished feed; Group 2 rats received malnourished feed with dosed 1.6 mg/g MSG per body weight; Group 3 rats were fed with normal feed and dosed 1.6 mg/g MSG per body weight and Group 4 rats served as the control group (normal healthy rats) and were fed with normal feed for 28 days. After 28 days, the rats were sacrificed with the liver harvested and blood samples collected. Results from the study showed that malnourished rats had significantly lower levels of oxidative stress biomarkers including, anti-oxidants compared with the control. The levels of malondialldehyde concentration and xanthine oxidase activity were high in malnourished fed rats. Aspartate aminotransferase and alanine transaminase levels of malnourished and normal rats administered MSG were significantly low compared to the normal healthy suggesting that labialization occurs in liver leading to leakage of these enzymes from the liver to the serum. Malnourished rats showed significant decrease in body weight losing 48 grams after 28 days compared to malnourished and normal rats fed with MSG which recorded significant increase in body weight after 28 days adding 26 g and 42 g respectively.

Feasibility Study for a Biogas Plant in Jordan

This research was conducted to estimate the economic feasibility of establishing biogas plant from dairy farms manure in Al-Dlail district (Zarqa governorate). Biogas is a mixture of gas consisting of 50-70% of methane and carbon dioxide 30-45%, and other gases and water that resulted from the digestion of the biomass process with the absence of oxygen. It is used as a fuel source in many countries for the purposes of lighting and cooking. Biogas is a clean and renewable form of energy that can be sustainable solutions of large organic waste produced in animal farms and reduces the harmful environmental pollution. Also, it can be an opportunity to invest and make profits. Data for this research was collected by desk research, survey and interviews. The respondents were 31 dairy farmers; the interview included the Jordan Biogas plant manager, owners of manure plants, heads of cattle breeders associations and stakeholders in government organization. The collected data were analyzed by using SPSS, 5P's analysis, PESTEC Analysis and Canvas model to come up with a clear picture about the feasibility of biogas utilization in Zarqa governorate. The study showed the tremendous environmental pollution that happened in Al-Dlail and Al-Khaldiah areas due to the poor management of cattle farms manure, causing air, soil ground and surface water pollution. As a solution to this problem, the study showed that the most appropriate solution to this problem is to exploit these manure in the production of energy from biogas as a sustainable, and environment-friendly project. The research also included the size of the feedstock of the manure produced from cattle farms, the availability of the necessary technology to build a project of this plant, the availability of markets for its products and the legislative framework governing the renewable energy projects represented by the Ministry of Energy. The study concluded that it is possible to establish a medium-sized biogas plant.

Floral Biology and Pollen Viability of Passiflora edulis Sims

Yellow passion fruit is a native tropical fruit tree whose cultivation has evolved very rapidly in Brazil; therefore, studies on the ecology of reproduction are needed. The study of pollen viability is an important tool to observe the male potential of the species. The objective of this study was to estimate pollen viability, pollen/ovule ratio and floral biology of Passiflora edulis Sims in organic cultivation located in Bananeiras, PB, and Brazilian. The study was developed in a completely randomized design, using ten flower buds in the pre-anthesis. The analyses performed in the biology laboratory of the Center of Human, Social and Agrarian Sciences of the Federal University of Paraiba. For the pollen viability analysis, all the anthers of the ten flower buds were used, five anthers per flower, which were crushed on a glass slide and with the aid of Alexander dye, the purple pollen grains were considered viable and the green ones unviable. To measure flower morphology and biometrics, a digital pachymeter, analytical balance and ruler were used. Five stamens form the androecium; the fillets are of short length inserted below the ovary. The flowers have three stigmas with an average height of 16.5mm, an average of 32,136 viable pollens, 58 unviable pollen grains and 140 ovules per ovary, having a pollen viability of 99.8% and a pollen/ovule ratio of approximately 95/1 pollen grains per ovule. Their structures are uniform, with no biometric variations in the amount of petals, sepals, anthers and stigma length. Alexander's reactive dye was effective in staining the pollen grains of yellow passion fruit. The pollen/ovule ratio indicates that this species performs facultative autogamy as well; however, this classification alone is not sufficient to affirm its reproductive system.

The Health Implication of Enterohaemorrhagic Escherichia coli (EHEC) 0157:H7: A Review on Haemolytic Uraemic Syndrome

Consumption of foods, water, vegetables, fruits, undercooked/ground/raw meat, unpasteurized milk or milk products contaminated with the bacterium strain Escherichia coli 0157:H7 has become a serious public health concern. This strain naturally inhabits the digestive tract of healthy cattle, and is released into the environment through the faeces of the animal. This strain cause haemorrhagic enterocolitis or gastroenteritis, and then haemolytic uraemic syndrome (HUS). HUS is a disorder characterised by haemolytic anaemia, low platelet count and acute kidney failure, and this disorder is a consequence of the production and action of Shiga-like toxin produced mainly by this bacterial strain (accounting for 90 percent of all cases), and occurs mainly in children less than five (5) years of age, but also occurs in the elderly. After infection with this bacterial strain, the disorder begins with intestinal perforation and ulceration leading to bloody diarrhoea, and consequently acute kidney injury, thrombocytopenia and microangiopathic haemolytic anaemia. In conjunction with clinical manifestations, several laboratory investigations (haematological, biochemical and microbiological assays) are implicated in the diagnosis of HUS. There is currently no specific treatment for HUS; however, supportive care (such as treatment of hypertension, fluid and electrolyte imbalance, haemodialysis, blood transfusion, etc) happens to be the only ameliorative measure for this disorder.
