No full textThis study investigated the use of inquiry teaching method in Social Studies to curb illicit drug usage among upper basic school students in Anambra Metropolis. Three research questions guided the study. The study examined the factors militating against curbing of the vices among students of the upper basic schools. A descriptive survey and quasi-experimental research using standardized achievement test and questionnaire was employed for the study. The achievement test questions were adapted from National Examination Council (NECO) past questions. The questionnaire items were developed by the researcher, but validated by experts. The reliability of the instruments was determined using test and re-test method and the coefficients of reliability obtained were 0.75 and 0.78 for achievement test and questionnaire respectively. The target population included all Upper Basic 9 students in three randomly selected local government areas in Anambra State, Nigeria. The sample was made up of 87 students, 58 in control group and 29 in experimental group. The data collected were analysed using mean and standard deviation to answer the research questions. The findings of the study revealed that inquiry teaching method is capable of curbing illicit use of drugs among Upper basic students. Based on the finding of this study, it was recommended among others that teachers should always use student-centred methods such as inquiry method which will engage the students deeply with mental work capable of distracting them from taking illicit drugs. Also, government should provide in-service training for teachers to keep them up to date with happenings in education world
THE MODIFIED RANDOM WALK DISTRIBUTION
No full textThis study presents a modification to a two-parameter distribution, yielding a discrete distribution termed the modified random walk distribution. This modification is derived from the random walk distribution and falls within the family of Lagrangian probability distributions. Comprehensive investigations are conducted on both the random walk distribution and its modified counterpart to discern and analyze their respective properties. Furthermore, a recursive formula for generating probabilities associated with this distribution is proposed. This research contributes to the understanding of the random walk distribution and provides insights into the implications of its modification
X-raying Foreign Direct Investment and Innovation Capability of SMEs in Lagos State
Get PDFIn the 21st century, socio-economic development has largely depends on the success of small and medium enterprises (SMEs). However, the sector has not been able to fully take advantage of FDI to enhance innovation capability of the ventures particularly in developing countries like Nigeria. The study, therefore, leverages dynamic capability theory to x-raying the influence of foreign direct investment on innovation capability of SMEs in Lagos State. A cross-sectional and random sampling techniques were employed to gather data from 382 SME owners/operators in Lagos State from the population of 8,395 out of which 365 were validly filled and returned via snowballing approach representing 95.6% response rate. The primary data were further subjected to statistical analysis using frequency, Pearson Product Moment correlation coefficient, and regression. The study found out that foreign direct investment has significant and positive effects on innovation capability of SMEs in Lagos State in the areas of idea management, service quality delivery, and competiveness. However, the findings of this study demonstrated that FDI has more effect on idea management than service quality delivery and competiveness. The study further proposes that the CEOs or managers in the space of SMEs should engage policymakers to ensure improved infrastructure and resources are in place to support FDI-SMEs intervention arrangement for the purpose of enhancing innovative ideas of the players towards global competiveness
INFLUENCE OF MARCIA’S MORATORIUM AND FORECLOSURE EGO IDENTITY STATUSES ON READING ATTITUDE OF STUDENTS IN SECONDARY SCHOOLS IN TANGAZA AND NEIGHBOURING AREAS IN SOKOTO STATE, NIGERIA
No full textThe paper studied how identity statuses of moratorium and foreclosure influenced the reading attitude of adolescent students in secondary schools in Tangaza and neighbouring areas. Correlational descriptive research design was used for the study. Six research questions and two hypotheses were formulated. A total of six sub-hypotheses were tested on Microsoft Excel software and www.statskingdom.com. The eleven senior secondary schools located in Tangaza, Silame, and Binji local governments formed the population of the survey. A three--stage sampling technique was used, consisting of stratified, purposive, and simple random sampling techniques. The sample for the study was 164 generated from three randomly selected schools; Instruments used in the research were the 16-item Ego Identity Scale (Short) (Greg, 2008) and the Reading Attitude Questionnaire adapted by Akhmetovaa, Imambayevab, and Csapo (2022). Pearson Product Moment Correlation (PPMC) was used to test the hypotheses. Results showed there was no significant relationship between moratorium and foreclosure ego identity statuses and reading attitude of the samples. The study recommended among others that parents, guardians and teachers should consistently guide and encourage adolescents to explore various options in different aspects of life and be committed to such according to their goals and aspirations as they develop into adults; students however should be encouraged by their teachers and parents to develop positive reading attitude as that is part of what lead to identity achievement
MARKOV SWITCHING DYNAMIC REGRESSION MODEL: APPLICATION TO FINANCIAL DATA
No full textHidden Markov Models are used to study occurrences where a portion of the phenomenon is observable while the rest is unobservable. The model consists of two sets of random variables, namely, unobservable and observable random variables. Markov models are usually used to model the unobservable variable part of the hidden Markov model; a time-series regression model is used to model the observable part of the model. Then, the two random variables produce a regime-switching model known as the Markov-switching dynamic regression model with a distinct probability distribution. The parameters of this resulting model can be estimated using the maximum likelihood estimation method, and the characteristics of the regression model vary with the presiding regime of the model. The regression objective of this work is to explain the variability in the Nigerian monthly inflation rates using the variability in the average monthly United States dollar exchange rates. The correlation between the two datasets is determined using the least squares regression model and the Markov switching dynamic regression model. The Markov switching regression (Regime 2) model represents the high-variance regime. It explains the regression objectives more than the OLS regression model, as shown in the results. Consequently, it shows that when the Markov state model is in the high variance regime, Nigeria's economy shows a recession. The results depict that the regime-switching model outperformed the single regime model in capturing the properties of the data from the comparative analysis
IMPULSIVE SALE-PROFIT MODEL
No full textThis paper considers optimization problems that arise from mathematical economics involving the impulsive sale-profit model of a company producing some items in a mechanically independent non-competitive market situation. The sale and profit profiles of the company are analyzed using a variable allocation of funds for sales promotions, minimizing the cost functional subject to impulsive control and Lyapunov Functional. We formulate the sales projection of the company using the `parasitic control measure' and the impulsive-averaging technique. The result shows that the sale is bounded in a redundant market situation if some sale parameters are finite. The approximate solution and the error of approximation of the model exist
Leadership Framework for Sustainable Housing Production in South Africa
No full textA primary objective of the United Nation's Sustainable Development Goals (SDG-9) is providing quality, affordable, reliable, sustainable and resilient infrastructure, for every part of the global community by 2030. This is also a fundamental principle in the New Urban Agenda by the UN-Habitat. Studies have shown lack of adequate and affordable housing in many African cities, evident in slums such as Kyelitsha in Cape Town, Makoko in Lagos, and Kibera in Nairobi which house millions of urban dwellers. In South Africa, Section 26 of the constitution establishes the citizens' right to have access to adequate housing as incontrovertible. In order to achieve this, the South African government put in place several policies to ensure the attainment of the right. However, scholars acknowledge the poor rate of housing delivery by the government and view it as a symptom of an inadequate response to urban populism and a lack of leadership in the housing sector. This paper examines how leadership failures have impeded housing policy and practice implementation in South Africa. The study employs a systematic literature review and case studies in showing how lack of leadership affects the attainment of adequate housing provision. The paper proposes a leadership framework for sustainable housing provision and good governance in the housing sector
Office Sustainability Assessment for Endearing Resilience in an Academic Environment
No full textOffice conditions are crucial to assessing the sociocultural, economic, environmental and public health of the majority of the urban population. The office is a built environment that takes up the bulk of the time and energy of society's elite. As such, the quality of office spaces has a significant effect on the health, comfort, satisfaction and productivity of office workers. No doubt, inadequate indoor environmental quality will impede workers' productivity and well-being. Sustainability in the office addresses the interface through which resilience in both the biotic and abiotic components of the indoor working micro-environment can be measured and transformed for full productivity. In the light of this, this article evaluates the factors driving infrastructural, health and economic resilience in academic institutions. The study reviews the literature on the theory of human behaviour, with a view to establishing the link between key concepts in infrastructural, health and economic resilience and office sustainability within an academic environment. It identifies office sustainability as a major determinant in the effective measurement and development of resilience in academic environments. It was observed that the dimensions of infrastructural, health and economic resilience are in-built features which academic institutions should adopt to achieve overall resilience in the academic environment. This assessment should bring about major social and economic benefits, given the quantum of time that members of the university staff spend in their office
Drug Supply Chain Management in Public Secondary Health Facilities in Lagos State Nigeria
Get PDFThis study was conducted to analyze the drug supply chain at nineteen selected public secondary health centers (SHC) commonly referred to as General Hospitals, in Lagos State. Data was collected from both primary and secondary sources. The primary data were collected through a well-structured questionnaire while the secondary data were sourced from journals, Lagos State Ministry of Health, Lagos Bureau of Statistics (LBS), National Agency for Food and Drug Administration and Control (NAFDAC), etc. A descriptive statistical method was employed for data analysis using the statistical package for Social Science (SPSS) version 2.0 and ArcGIS 10.8 version. Maps, frequency counts, percentages, and analysis of variance (ANOVA) were also used to test the hypothesis The study contributed to the existing body of knowledge by establishing the Euclidean distance of SHC from Central Medical Store (CMS) Oshodi, the residences within and outside the buffer zone of 2km radius around the SHC in Lagos state and the distribution and accessibility of patients to essential drugs in the study area. Findings confirmed that 79.6% of Pharmacists have received training on supply chain practices. The respondents also said that SHC in Lagos gets about 75% of their drug supplies from Central Medical Store. The result also revealed there is a significant relationship between the number of dispensing outlet and the amount paid for drug by patients. Also, 57.5% of the patients preferred to have their drugs delivered at home and 49.5% were willing to pay extra cost for home delivery. The study suggests strong regulation and strict enforcement of National Drug Distribution Guidelines of 2012 (NDDG) by the regulator. The study concludes that effective supply chain will deliver safe, efficient, and quality drugs to meet the health need of the patients
