Impact of E-Government on Governance Service Delivery in Nigeria

E-government has become an important practice among public sector in Nigeria. The introduction of E-government services such as IT usage and other web-based telecommunication technologies enhance improvement in the efficiency and effectiveness of service delivery in the public sector, It was in line with this that the study aim at examine the influence of e-government on governance service delivery in Nigeria. The study were carried out in Ogun state with One hundred and fifty (150) Questionnaires administered and distributed to both senior & junior staff of the Three selected Ministry, fifty (50) staff each was picked from the three (3) selected government parastatal (Ministries). One hundred and Twenty five (125) Questionnaires were found useful for the purpose of the study. Data collected was analyzed using frequency table and percentage analysis while the non-parametric statistical test Chi- square was used to test the formulated hypothesis using STATA 10 data analysis package/software. Findings show that Electronic system of Operation help government workers to display technological skills and connect them with other world and also reduce the stress of queue in government ministries and department by citizens dealing with government . the result of tested hypothesis buttress that E-government improve service delivery by the public sector in a form of transactional convenience, savings of time and save of service cost which has recuperate customer’s relationship and satisfaction. To this end, it is recommended that Government should create awareness to the public about the benefit on the e-government services, skilled manpower and computer wizard should be employed by every government parastatals in order to meet up with the digital world or economy. Finally Government should establish a commission on ICT to regulate the sector and to see to the full implementation of e-government.

Regulation of Cation-Coupled High-Affinity Phosphate Uptake in the Yeast Saccharomyces cerevisiae

ABSTRACT Studies of the high-affinity phosphate transporters in the yeastSaccharomyces cerevisiae using mutant strains lacking either the Pho84 or the Pho89 permease revealed that the transporters are differentially regulated. Although both genes are induced by phosphate starvation, activation of the Pho89 transporter precedes that of the Pho84 transporter early in the growth phase in a way which may possibly reflect a fine tuning of the phosphate uptake process relative to the availability of external phosphate.
A Machine Learning Approach to SDL

Security Risk Assessments (SRA) play a key role in the Security Development Lifecycle (SDL). At an early stage of the project, the SRA helps allocate security resources and identifies SDL requirements and activities. In this paper, we present key findings from a machine learning approach toward the SRA that seeks to learn from a database of previous product security risk assessments and associated requirements and activities. This approach has been implemented and adopted by product teams across our organization.
Identifying the characteristics of and quality indicators for associate degree culinary arts programs: A survey of educators and industry

Identifying the Characteristics of and Quality Indicators for Associate Degree Culinary Arts Programs: A Survey of Educators and Industry by Jean Louise Hertzman Dr. Robert Ackerman, Examination Committee Chair Associate Professor of Educational Leadership University of Nevada, Las Vegas Since 1981, the number of associate degree culinary arts programs in the United States increased from four to 261. Little academic literature exists about these programs and their diversity makes clear comparisons of culinary programs difficult. This study addresses the research question; What are the common characteristics of associate degree culinary arts programs and to what extent can each of these characteristics be used as indicators for evaluating the quality of the programs? The researcher performed content analysis o f232 associate degree culinary arts program requirements worksheets to determine the typical curriculum. She analyzed information from guidebooks and websites to develop a database of the characteristics of 261 programs. The researcher conducted a thorough literature review of quality assessment theories and ranking and accreditation systems. Using Dillman’s (2002) Tailored Design Method, she developed a survey to assess culinary educators’ and industry chefs’ perceptions of the importance of teaching specific professional and general education subjects in
Performance assessment of cascade control systems based on LQG benchmark

Given that the LQG benchmark is closer to the actual production, performance assessment of cascade control system based on LQG benchmark has been proposed. The joint input and output subspace identification algorithm was used to estimate the process model, noise transfer function, the inner loop controller and the outer loop controller. And three possible cases could be considered to evaluate cascade control systems. First, none of the inner and outer controllers were known and the goal was to design both controllers to get the global optimum. Second, the outer controller was considered to be fixed and one was looking for the best achievable performance by designing the inner controller. Third, the inner controller was considered to be fixed and one was looking for the best achievable performance by designing the outer controller. These three scenarios were used to evaluate the performance of the global, the inner controller performance and the outer controller. According to the simulation results, performance assessment of cascade control systems based on the LQG benchmark not only get the global performance of the system, but also show how much improvement may be achieved by designing inner and outer controllers.
10 W GaInP/GaAs power HBTs for base station applications

Reports on GaInP/GaAs HBTs suitable for high voltage operation as required for base station amplifiers. The high breakdown voltages are achieved by adjusting thickness and doping level of the collector layer. Record BV/sub cbo/ and BV/sub ceo/ values of 80 V and 47 V, respectively, are obtained for a 3.5 /spl mu/m thick collector doped to 4 /spl times/ 10/sup 15/ cm/sup -3/. In order to realize the very high transistor mesa of more than 5 /spl mu/m reliably, the standard HBT process was modified. HBT operation at 2 GHz for high supply voltages up to 32V is demonstrated. Good RF performance is confirmed by f/sub T/ values higher than 20 GHz and usable current densities in excess of 1 /spl times/ 10/sup 4/ A/cm/sup 2/. Power HBTs with an emitter area of up to 5000 /spl mu/m/sup 2/ deliver 10 W of output power at 2 GHz with high efficiencies (PAE=50-79%) and 8-13 dB gain. Compared to LDMOS devices, these power HBTs exhibit a much larger output impedance (e.g., 20 /spl Omega/ for a 4000 /spl mu/m/sup 2/ device), which facilitates combining to very large power amplifiers. Heat-sinking strategies for high power HBTs are discussed based on power results and thermal simulations.
Report: Improving CNN by Reusing Features Trained with Transductive Transfer Setting

The behavioral neuroscientist believe that the knowledge gained to distinguish an apple becomes useful when one tries to distinguish a orange or a pear. The study of transfer learning is inspired by this ability of human to a learn from a problem and able to reuse on a different but related problem. Reusing the knowledge of a network trained on source problem S to improve performance of target problem T to attain its goal function is called transfer learning and we use “⇒” symbol to denote transference. The various types of transfer learning approaches and settings are discussed in [1][2]. In Inductive transfer learning solves a more general problem before solving a more specific problem. In this case, distributions from source and target problems are related, P (XS) ≈ P (XT ). In transductive transfer the machine trains on a specific problem to solve another specific problem. In this paper we are interested in transductive transfer problems with arbitrary distribution but not necessarily related to the distribution of the source problem P (XS) 6= P (XT ). In this paper we are interested in transductive transfer setting as it performs better than inductive transfer settings from Vladmir Vapnik et al. [12] and Chetak et al. [1]. Let design data set Xds = {x1, x2, . , xn} has nds distinct training instances. These nds instances are assumed to be random samples with probability distribution P (X) from the classifier input X. The label set Ω = {1, . , c} has c distinct class labels. The source and target problems may have complete or partial or no information about labels. Even when the information is available, the label set for the source ΩS and target ΩT may be same or different. Similarly the number of instances for the source nS and target nT may be equal or different. The features (or filters) corresponds to a vector of weights and biases of neural network. The feature set w = { w, w, . , w } represent features of K
Assessment of Aspergillus‐specific PCR as a screening method for invasive aspergillosis in paediatric cancer patients and allogeneic haematopoietic stem cell recipients with suspected infections

Invasive aspergillosis (IA) remains difficult to diagnose in immunocompromised patients, because diagnostic EORTC/MSG criteria are often not met. As biomarkers might elucidate the pathogen, we analysed the performance of an Aspergillus PCR assay in blood for diagnosis of IA in immunocompromised paediatric patients with suspected infections. Ninety‐five haemato‐oncological paediatric patients were included over a period of 3 years, the underlying diseases consisting of acute leukaemia, solid tumours, non‐malignant immunocompromising disorders and haematopoietic stem cell transplantation recipients. We retrospectively analysed 253 consecutive episodes of suspected infections. Thirty‐eight patients had possible IA, none of the patients fulfilled EORTC/MSG criteria of probable/proven IA. PCR positivity was observed in 97/967 analyses. Sensitivity, specificity, positive and negative predictive value of the PCR per episode were 34%, 78%, 31% and 81% using possible IA as endpoint. Taken together, an undirected blood screening by Aspergillus‐specific PCR is of little diagnostic value in a heterogenous paediatric patient cohort. Harnessing PCR for diagnosis of IA should thus be focused on blood analyses of more homogenous high‐risk patients and/or analyses of bronchoalveolar lavage, tissue or cerebrospinal fluid specimens.
Complementation and Epistasis in Viral Coinfection Dynamics

Coinfection in RNA virus populations results in two important phenomena, complementation and recombination. Of the two, complementation has a strong effect on selection against deleterious mutations, as has been confirmed in earlier studies. As complementation delays the purging of less-fit mutations, coinfection may be detrimental to the evolution of a virus population. Here we employ both deterministic modeling and stochastic simulation to explore the mechanisms underlying the interactions between complementation and other evolutionary factors, namely, mutation, selection, and epistasis. We find that strong complementation reduces slightly the overall fitness of a virus population but substantially enhances its diversity and robustness, especially when interacting with selection and epistasis.
Largeur de seuil dans les lois du Zéro-Un

Ce travail de these prolonge les developpements recents, dus a Talagrand, Friedgut et Kalai de l'etude des conditions generales assurant l'existence d'un phenomene de seuil. Dans une premiere partie, nous apportons une contribution a l'unification du cadre theorique des phenomenes de seuil, d'une part en reliant rigoureusement le cadre originel des ``fonctions seuils'' introduit par Erdos et Renyi, celui des travaux de Friedgut et Kalai et la concentration du temps d'atteinte de la propriete qui suit le phenomene de seuil; d'autre part en initiant une recherche sur la stabilite des phenomenes de seuil par trois types d'operations: l'union, l'intersection et le produit tensoriel. On obtient ainsi un moyen simple de construire des largeurs de seuil d'ordres varies. Dans une seconde partie, on optimise la majoration generale de la largeur de seuil d'une propriete croissante et symetrique, a l'aide de l'inegalite de Sobolev logarithmique sur l'hypercube discret.
Motivations of R&D team participating in knowledge collaboration : A game analysis and empirical study

Abstract The study on motivation internal knowledge collaboration(KC) is of great importance to the better management and motivating team members to participate in the KC in a more positive way. Firstly, this paper studies on the signaling game analysis of knowledge heterogeneity in the community based on a two-period reputation model. The results show that knowledge providers have enough driving force to participate in collaborative activities. Then, we explored the motivating factors that affect R&D team members’ participation in KC and constructs the theoretical model, which shows that personal reputation, sharing willingness and group identification have different effects on the motivations of knowledge providers involved in organizational learning; exploitative learning and explorative learning have significant impacts on collaborative innovation performance, and the impact of the former is bigger than the latter; and the team motivation has regulating effect on the relationship between organizational learning and innovation performance of KC.
The relation between amino acids and potassium in isolated rat muscle.

principally lysine. Furthermore, an extensive series of experiments from Christensen's laboratory had demonstrated an intimate relation between amino acid and potassium metabolism in Ehrlich ascites tumor cells (4). Consideration of these data led us to investigate the effect of cationic amino acids on potassium metabolism in our in vitro mammalian muscle preparation.
Running head : AGE PATTERNS IN RISK TAKING ACROSS THE WORLD Age Patterns in Risk Taking Across the World Revised

Epidemiological data indicate that risk behaviors are among the leading causes of adolescent morbidity and mortality worldwide. Consistent with this, laboratory-based studies of age differences in risk behavior allude to a peak in adolescence, suggesting that adolescents demonstrate a heightened propensity, or inherent inclination, to take risks. Unlike epidemiological reports, studies of risk taking propensity have been limited to Western samples, leaving questions about the extent to which heightened risk taking propensity is an inherent or culturally constructed aspect of adolescence. In the present study, age patterns in risk-taking propensity (using two laboratory tasks: the Stoplight and the BART) and real-world risk taking (using self-reports of health and antisocial risk taking) were examined in a sample of 5,227 individuals (50.7% female) ages 10-30 (M = 17.05 years, SD = 5.91) from 11 Western and non-Western countries (China, Colombia, Cyprus, India, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the US). Two hypotheses were tested: (1) risk taking follows an inverted-U pattern across age groups, peaking earlier on measures of risk taking propensity than on measures of real-world risk taking, and (2) age patterns in risk taking propensity are more consistent across countries than age patterns in real-world risk taking. Overall, risk taking followed the hypothesized inverted-U pattern across age groups, with health risk taking evincing the latest peak. Age patterns in risk taking propensity were more consistent across countries than age patterns in real-world risk taking. Results suggest that although the association between age and risk taking is sensitive to measurement and culture, around the world, risk taking is generally highest among late adolescents.
Low Voltage Ride Through(LVRT) control strategy of grid-connected variable speed Wind Turbine Generator System

In this paper, a Low Voltage Ride Through (LVRT) control strategy for variable speed full scale Wind Turbine Generator System (WTGS) is proposed. Grid-connected wind power system should satisfy LVRT requirement when grid fault occur, and the variable speed full scale WTGS has advantage of satisfying LVRT compared with the fixed speed WTGS. The proposed LVRT control strategy satisfies not only LVRT requirement but also stabilizing a DC link voltage regardless of reduced DC link capacitance. During the grid faults, especially three phase to ground fault, the grid side converter cannot control the DC link voltage because it is impossible to control grid side power. In this situation, the DC link voltage can be controlled by the generator side inverter using the proposed DC link voltage control scheme. The proposed control scheme can keep the power balance between grid and generator side power in any case of grid fault condition for LVRT. The compliance to Grid Codes has been evaluated by computer simulations. Though the experimental results, it is verified that the proposed method has satisfied the LVRT requirements and DC link voltage control specification simultaneously.
Mapping local pH in live cells using encapsulated fluorescent SERS nanotags.

Understanding uptake and processing of nanomaterials by cells has implications for therapeutics and diagnostics. Although nanoparticle agents have been developed as proven imaging agents and promising drug-delivery vehicles, much remains to be learned regarding their internalization as local environmental sensors, even for the relatively simple case of pH determination at the nanoscale. Strategies for in vitro cell culture have been reported that use cargo-containing or dyelabeled nanoparticles with a cationic agent, which promotes binding to the cell membrane through an electrostatic interaction, inducing the cell membrane to wrap around the particle, which is then internalized through endocytosis. Nutrients and molecules that are not able to cross the membrane through active transport or diffusion and inorganic particles bigger than a few nanometers use this route. This complex process is also exploited in the uptake of nucleic acids, drugs and peptides, and of polymers for drug delivery, sensing and biocompatibility applications. Although promising efforts to monitor the interior pH in a cell after endocytosis of pHsensitive dual-color fluorescent polymers have been reported, issues of photostability and wavelength optimization remain. An ideal nanoprobe would be photostable, sensitive, and excitable with near-infrared (NIR) wavelengths at which cells and tissues are somewhat transparent and autofluorescence is minimized. A wide range of fluorescence-based materials have been developed as imaging agents and as local probes of the presence of specific biomarkers or of local environmental conditions. For example pH-sensitive fluorescence probes have been used to determine the time-dependent acidity of endosomes through a comparison of the intensity ratio between two
Condensin but not cohesin SMC heterodimer induces DNA reannealing through protein–protein assembly

Condensin and cohesin are chromosomal protein complexes required for chromosome condensation and sister chromatid cohesion, respectively. They commonly contain the SMC (structural maintenance of chromosomes) subunits consisting of a long coiled‐coil with the terminal globular domains and the central hinge. Condensin and cohesin holo‐complexes contain three and two non‐SMC subunits, respectively. In this study, DNA interaction with cohesin and condensin complexes purified from fission yeast was investigated. The DNA reannealing activity is strong for condensin SMC heterodimer but weak for holo‐condensin, whereas no annealing activity is found for cohesin heterodimer SMC and Rad21‐bound heterotrimer complexes. One set of globular domains of the same condensin SMC is essential for the DNA reannealing activity. In addition, the coiled‐coil and hinge region of another SMC are needed. Atomic force microscopy discloses the molecular events of DNA reannealing. SMC assembly that occurs on reannealing DNA seems to be a necessary intermediary step. SMC is eliminated from the completed double‐stranded DNA. The ability of heterodimeric SMC to reanneal DNA may be regulated in vivo possibly through the non‐SMC heterotrimeric complex.
Kiosk: An Innovative Client Centric Approach to Tuberculosis Prevention and Care

Kiosk is a client centric drop-in centre for TB information and services established in urban and peri-urban (slum) settings to provide outreach services under project Axshya. The main objective of the study was to demonstrate the efficacy and feasibility of scaling-up of the model to provide TB services. The assessment was carried out with the help of project recording and reporting formats used to document the information and services provided in the Kiosk from April 2016 to March 2017. The results from retrospective data analysis for services provided at 20 kiosks benefited 16,871 clients; of these 11,252 (66.7%), 1339 (7.9%), 848 (5%), 2911 (17.2%), (1.4%), 273 (1.6%) benefited with TB information, Flexi-DOT, sputum-collection-transportation (SCT), counselling, and domiciliary care respectively. Through active case finding (ACF); 126,893 households were visited and 3593 presumptive-TB-patients received SCT services. A total of 329 TB patients were identified and linked to treatment services of national TB programme. “Kiosk” as a client centric approach would be a novel concept to ensure TB information, TB related services and contribute to ongoing efforts of TB case finding.
