A 10 Years Review and Classification of the Geographic Information Systems Impact Literature (1998-2008)

Our objective in this paper is to review the literature on the impact of geographic information systems (GIS) in governmental and non-governmental organizations by analyzing 53 articles published between 1998 and 2008. The impacts of GIS are categorized in a taxonomy which designates GIS contributions to efficiency, effectiveness and societal well-being. According to this taxonomy, 38 articles are examined in-depth and their results reported. The focus of GIS impact research efforts in terms of research philosophies, methodologies and geographic focus is also presented. We suggest that the appropriate use of theories, concepts and testing of existing GIS evaluation frameworks could serve as building blocks for more rigorous studies on the impact of GIS, including Land Information Systems (LIS) and Spatial Data Infrastructure (SDI)

PLASMID PROFILE OF ANTIBIOTIC RESISTANT BACTERIA IN SACHET WATER SAMPLES SOLD IN ABEOKUTA, SOUTHWEST, NIGERIA

Antibiotic sensitivity pattern of bacterial isolates obtained from sachet water from Abeokuta, Ogun State, Nigeria was investigated.ª¤? A total of 300 sachet water samples were collected during the dry and rainy season of 2011 to 2012. Selected physicochemical analysis of the sachet water showed a pH range of 5.5-6.5, turbidity of 1.0 «¤??1.5 NTU and temperature of 28-300C. The mean aerobic mesophilic bacterial count of the sachet water samples ranged from 13.4 x 103 «¤?? 18.7 x 103 CFU/mL, while the mean total coliform count ranged from 0.153 - 0.163 x 103 CFU/mL. The physicochemical parameters of the sachet water samples were within the WHO standard for potable water. Bacteria isolated from sachet water samples include Escherichia coli, Klebsiella sp, Enterobacter sp and Pseudomonas aeruginosa. Most of the isolates were highly sensitive to Levoxin and Ceftazidime. Plasmid analyses revealed that there were detectable plasmids in 7.1% of the 14 multi-drug resistant isolates. Cured plasmid encoded resistant isolates were susceptible to Ceftazidime, Ceftriaxone, Gentamycin, Augmentin and Streptomycin

Access to water in the countries of the former Soviet Union.

BACKGROUND: During the Soviet period, authorities in the USSR invested heavily in collective farming and modernization of living conditions in rural areas. However, many problems remained, including poor access to many basic amenities such as water. Since then, the situation is likely to have changed; economic decline has coincided with migration and widening social inequalities, potentially increasing disparities within and between countries. AIM: To examine access to water and sanitation and its determinants in urban and rural areas of eight former Soviet countries. METHODS: A series of nationally representative surveys in Armenia, Belarus, Georgia, Moldova, Kazakhstan, Kyrgyzstan, Russia and Ukraine was undertaken in 2001, covering 18,428 individuals (aged 18+ years). RESULTS: The percentage of respondents living in rural areas varied between 27 and 59% among countries. There are wide urban-rural differences in access to amenities. Even in urban areas, only about 90% of respondents had access to cold running water in their home (60% in Kyrgyzstan). In rural areas, less than one-third had cold running water in their homes (44% in Russia, under 10% in Kyrgyzstan and Moldova). Between one-third and one-half of rural respondents in some countries (such as Belarus, Kazakhstan and Moldova) obtained their water from wells and similar sources. Access to hot running water inside the homes was an exception in rural households, reflecting the lack of modern heating methods in villages. Similarly, indoor access to toilets is common in urban areas but rare in rural areas. Access to all amenities was better in Russia compared with elsewhere in the region. Indoor access to cold water was significantly more common among rural residents living in apartments, and in settlements served by asphalt roads rather than dirt roads. People with more assets or income and living with other people were significantly more likely to have water on tap. In addition, people who had moved in more recently were more likely to have an indoor water supply. CONCLUSIONS: This was the largest single study of its kind undertaken in this region, and demonstrates that a significant number of people living in rural parts of the former Soviet Union do not have indoor access to running water and sanitation. There are significant variations among countries, with the worse situation in central Asia and the Caucasus, and the best situation in Russia. Access to water strongly correlates with socio-economic characteristics. These findings suggest a need for sustained investment in rebuilding basic infrastructure in the region, and monitoring the impact of living conditions on health

Resistant plasmid profile analysis of multidrug resistant Escherichia coli isolated from urinary tract infections in Abeokuta, Nigeria

Background: Multi-drug resistant Escherichia coli has become a major threat and cause of many urinary tract infections (UTIs) in Abeokuta, Nigeria.Objectives: This study was carried out to determine the resistant plasmids of multidrug resistant Escherichia coli isolated from (Urinary tract infections)UTIs in Abeokuta.Methods: A total of 120 Escherichia coli isolates were obtained from urine samples collected from patients attending inpatient and outpatient clinics presenting UTI; with their biodata. Antibiotics susceptibility was performed and multi-drug resistant isolates were selected for plasmid profiling. Plasmids were extracted by the alkaline lysis method, electrophoresed on 0.8% agarose gel and profiled using a gel-photo documentation system gel.Results: Escherichia coli isolates obtained shows high resistance to cloxacillin (92.5%), amoxicillin (90.8%), ampicillin (90.8%), erythromycin (75.8%), cotrimoxazole (70.0%), streptomycin (70.0%) and tetracycline (68.3%) while 85.8% and 84.2% were susceptible to gentamycin and ceftazidime respectively. Sixteen Escherichia coli strains were observed to be resistant to more than two classes of antibiotics. The resistant plasmid DNA was detectable in 6(37.5%) of the 16 multidrug resistant Escherichia coli having single sized plasmids of the same weight 854bp and were all resistant to erythromycin, cefuroxime, cloxacillin, amoxicillin, ampicillin and cotrimoxazole.Conclusion: This study has highlighted the emergence of multidrug resistant R-plasmids among Escherichia coli causing urinary tract infections in Abeokuta, Nigeria. There is a high level of resistance to many antimicrobials that are frequently used in Abeokuta, Nigeria.Keywords: Escherichia coli, UTI, R-plasmid, multidrug resis

Satisfaction and perceived impact of virtual learning during COVID-19 lockdown: A case study of an online nursing research conference

Aim This study aimed to assess nurses' satisfaction and perceptions of the impact of virtual learning. Design A descriptive cross-sectional survey. Method 236 nurses attending an online conference from several parts of Nigeria participated in the study. Analysed data were summarized and presented in tables and graphs, while linear regression was used to measure the associations. Results Most of the respondents perceived the programme as highly impactful. All three domains: learner-content interaction (p?=?0.020), learner?instructor interaction (p?=?0.000) and learner?learner interaction (p?=?0.000), were found to be statistically significantly associated with the perceived impact of the programme, and thus statistically significant predictors of the effects of online learning (p?=?0.02), (F?=?5.471). Conclusively, the Interaction of learners with learning content, lecturers and other learners was seen as determinants of an effective and impactful online education. It is recommended that nursing training institutions embrace online learning either as the leading platform or as an adjunct to a face-to-face method

Evaluation of equity in informal land development systems in two Nigerian cities

The informal land development system in Sub-Saharan Africa (SSA) is perceived to promote equity and could be leveraged to support sustainable urban development and management. However, scanty empirical evidence exists on the extent of the system’s provision of equity to support policy formulation and practice in the region. Based on stakeholder workshops, focus group discussions and questionnaire surveys, this study analyses the system’s provision of equity in Nigeria. The study finds all categories of people undertake informal developments. Consistent with literature, this finding reflects wide patronage of the informal land development system and its relevance. Nevertheless, contrary to the existing perception, the system’s provision of equity is low. The study recommends for the institution of pro-poor and gender sensitive land development and management policies and programmes to increase the levels of equity to support the achievement of the country’s sustainable urban development and management agenda

Detection of Low-Avidity Immunoglobulin G in Oral Fluid Samples: New Approach for Rubella Diagnosis and Surveillance

Low-avidity rubella immunoglobulin G (IgG) was detected in oral fluid samples from 30 of 32 rubella IgM-positive patients (sensitivity, 94%) and from 4 of 34 IgM-negative patients (specificity, 88%). Measuring IgG avidity in oral fluid samples could improve the reliability of rubella surveillance when the incidence of the disease and the positive predictive value of IgM tests are low
