e-Government development: Benchmarking Ghana and Tanzania

Using time-series data from the United Nations e-government Surveys, this paper presents the comparative assessment of e-government (e-gov) in Ghana and Tanzania over the last two decades. The findings confirm tremendous progress in e-government development in bothnations. However, while Ghana has made significantly moreprogress, the indicators for both countries are below th eworld averages, suggesting the need for strategies to boost e-gov development. Furthermore, to accelerate e-gov implementation, both nations need to go beyond systematizing existing procedures by engineering new practices to transform the relationship between government and citizens

Management Practices to Enhance the Effectiveness of Substance Use Disorder Treatment

Managers of substance use disorder (SUD) treatment organizations face significant challenges to improve treatment effectiveness. The field has paid significant attention to the delivery of pharmacological and psychosocial treatment interventions, and the effectiveness of these interventions, with little consideration for the role of management practices that enhance the delivery of such evidence-based practices (EBPs). This chapter describes evidence-based management practices (EBMPs) that may support the effective and consistent delivery of EBPs in SUD treatment. Drawing from a socio-technical and cultural framework, we propose a management approach that relies on policies, human resources, and culturally responsive practices to directly and or indirectly facilitate the delivery of EBPs. In particular, this chapter describes EBMPs that could be widely implemented to respond to the cultural, linguistic, and service needs of racial and ethnic minority groups. We discuss implications for funding and support of management training to improve standards of care and include a case example to promote reflection

Evaluation Of Four Local Materials As Backfill To Achieve A Low Earth Electrode Resistance

In this study, the efficiency of materials available for free, namely palm kernel oil cake, tyre ash, wood ash and powdered cocoa shell, as conductive backfill for reducing earth electrode resistance was evaluated. Earth rod of 30-cm length and 14-mm diameter was installed for each backfilling material at a site and their performance compared with that of a reference earth rod also installed at the same site. The results show that tyre ash provides a stable earth electrode resistance in both dry and wet weather conditions and improves it to about 16%

What drives me there? The interplay of socio-psychological gratification and consumer values in social media brand engagement

The social behavioral perspective is under-researched in the extant literature. This hinders the holistic understanding of social media brand engagement. This study examines the interplay of socio-psychological gratification variables (perceived homophily, perceived critical mass, and self-status seeking) and consumer values (personal, interpersonal, and fun) on consumer participation in social media brand engagement. The conceptual model in this study is situated on the principles of Uses and Gratifications, Critical Mass, Homophily, and Values theories. Based on an online survey of 713 Facebook users, we examine the model using structural equation modeling (with Amos 23.0). The analysis disclosed insights on the interplay of motivational factors that underlie social media brand engagement. Our findings suggest that socio-psychological gratification variables (perceived homophily, perceived critical mass, and self-status seeking) drive consumers’ engagement with brand pages and brand communities on social media. This relationship is strengthened by the consumer values. These insights serve as an important basis for researchers and practitioners to understand social media brand engagement and its outcomes

Stochastic Modeling Of Decarbonizing Strategy, Policy, And Market-induced Incentives For The US Electricity Sector

In line with the global pursuit of achieving net-zero carbon emissions, integrating carbon capture and storage (CCS) and renewable energy (RE) technologies is important in power production. This study evaluates the profitability of CCS and RE technologies as alternative ways of achieving climate change goals. While past research focused on costs, technological advancements, and capture methods, there is a need for more studies on assessing the financial feasibility of these climate change solutions under uncertain conditions, alongside specific performance goals and strategies to entice power producers. Using a comprehensive framework featuring deterministic and stochastic modeling approaches, this research explores the impact of policy and market incentives on CCS and RE investments within the U.S. power sector. It analyzes the interactions of variables such as market uncertainties, technical factors, and policy dynamics on the financial viability of adopting CCS and RE for targeted CO2 reductions. The results reveal that, given the status quo of policies, RE and CCS exhibit annualized net present values of $4.62 and$1.76, respectively, for each metric ton (MT) of CO2. Uncertainties in policy incentives emerge as a primary hindrance to achieving cost-effective carbon reduction mandates using CCS, while changes in the green electricity price premium cause high variability in RE returns. The study proposes a hypothetical market, featuring the sale of CCS-linked net-zero electricity at a distinctive premium price of $0.03/kWh. The study\u27s findings underscore the importance of both policy and market incentives to enable power producers to deploy carbon management technologies at a large scale

Exploring the role of traditional authorities in managing the public as stakeholders on PPP projects: a case study

Previous research indicates that involving representatives of the public in stakeholder management increases the likelihood of obtaining successful outcomes when managing the public as stakeholders on PPP projects. Relatively little is however known about the exact roles played by traditional authorities, who are powerful public representatives and significantly influence the public and the stakeholder management process on PPP projects worldwide. A case study of a PPP was conducted to explore this question. Through a thematic analysis of data collected from multiple sources, four main roles of traditional authorities were identified: mediation; project monitoring; community representation; and custody management of community culture and physical resources. These roles and their associated outcomes make traditional authorities a crucial link between project executors and the public during stakeholder management. This study provides a step towards developing strategies for collaborating with traditional authorities for better stakeholder management of the public on PPP projects

Correlates of HIV testing and receipt of test results in addiction health services in Los Angeles County

Background HIV testing and receipt of HIV test results among individuals with substance use disorders is less than optimal. We examined rates and correlates of HIV testing and receipt of test results in one of the largest public addiction health services systems in the United States. Methods The study included 139,516 adult clients in treatment between 2006 and 2011. We used logistic regression models to examine associations between predisposing, enabling, and need factors and two dependent variables, HIV testing rates and receipt of test results. Associations were considered statistically significance at p < .01. Results We found that 64 % of clients reported being tested for HIV, of whom 85 % reported receiving their test results. Likelihood of being tested was positively associated with being female, a minority, homeless, employed, having prior treatment episodes, comorbidities, injection drug use, or a history of mental illness. It was negatively associated with alcohol or marijuana as primary drug. Receipt of test results was more likely among clients on medication (methadone or buprenorphine) or whose method of drug use was smoking, inhalation, or injecting; it was less likely among older clients and those with more outpatient psychiatric visits. Conclusions Findings from this study may inform strategies and targeting of population groups to improve HIV testing practices and ultimately increase awareness of infection status among clients of addiction health services

Awareness and knowledge of glaucoma among adult patients at the eye clinic of a teaching hospital

Background: Primary open angle glaucoma (POAG) is an irreversible blinding disease that often presents late because it is symptomless in the early stages. Prognosis depends on early diagnosis and treatment and patient understanding of their condition. Many patients present late because of poor awareness and knowledge. This study was conducted to assess patient’s awareness and knowledge of glaucoma in a referral Teaching Hospital.Methods: Descriptive cross-sectional study conducted among glaucoma patients aged 40 years and above attending the Komfo Anokye Teaching Hospital (KATH). Patients were selected by simple random sampling. They were recruited after informed consent had been given. A questionnaire on demographics, socio-economics and awareness of glaucoma was administered.Results: There were a total of 117 participants, 61 males and 56 females. The median and modal age group was 50 and 59 years. Amongst the participants, 74% were aware of glaucoma. There were no significant statistical difference in the various age groups, sex, ethnic group or religion and their awareness of glaucoma (P&gt;0.05).There were statistically significant differences between those who had higher education and their awareness of glaucoma (P&lt; 0.001). Yet only 27% of these had accurate knowledge of glaucoma.Conclusion: Glaucoma awareness in patients attending Komfo Anokye Teaching Hospital is high. Higher education was associated with higher awareness yet this was not translated into accurate knowledge as there were significant misconceptions .There is the need to review the contents of health education with the aim of reducing dangerous misconception of glaucoma and targeting the lower socioeconomic population.Key words: Glaucoma, Primary Open Angle Glaucoma, Knowledge, Awareness, Blindnes

Stabilizing contributions of sulfur-modified nucleotides: crystal structure of a DNA duplex with 2′-O-[2-(methoxy)ethyl]-2-thiothymidines

Substitution of oxygen atoms by sulfur at various locations in the nucleic acid framework has led to analogs such as the DNA phosphorothioates and 4′-thio RNA. The phosphorothioates are excellent mimics of DNA, exhibit increased resistance to nuclease degradation compared with the natural counterpart, and have been widely used as first-generation antisense nucleic acid analogs for applications in vitro and in vivo. The 4′-thio RNA analog exhibits significantly enhanced RNA affinity compared with RNA, and shows potential for incorporation into siRNAs. 2-Thiouridine (s(2)U) and 5-methyl-2-thiouridine (m(5)s(2)U) are natural nucleotide analogs. s(2)U in tRNA confers greater specificity of codon–anticodon interactions by discriminating more strongly between A and G compared with U. 2-Thio modification preorganizes the ribose and 2′-deoxyribose sugars for a C3′-endo conformation, and stabilizes heteroduplexes composed of modified DNA and complementary RNA. Combination of the 2-thio and sugar 2′-O-modifications has been demonstrated to boost both thermodynamic stability and nuclease resistance. Using the 2′-O-[2-(methoxy)ethyl]-2-thiothymidine (m(5)s(2)Umoe) analog, we have investigated the consequences of the replacement of the 2-oxygen by sulfur for base-pair geometry and duplex conformation. The crystal structure of the A-form DNA duplex with sequence GCGTAT*ACGC (T* = m(5)s(2)Umoe) was determined at high resolution and compared with the structure of the corresponding duplex with T* = m(5)Umoe. Notable changes as a result of the incorporation of sulfur concern the base-pair parameter ‘opening’, an improvement of stacking in the vicinity of modified nucleotides as measured by base overlap, and a van der Waals interaction between sulfur atoms from adjacent m(5)s(2)Umoe residues in the minor groove. The structural data indicate only minor adjustments in the water structure as a result of the presence of sulfur. The observed small structural perturbations combined with the favorable consequences for pairing stability and nuclease resistance (when combined with 2′-O-modification) render 2-thiouracil-modified RNA a promising candidate for applications in RNAi
