Department of Water Resources and Environmental Engineering, Ahmadu Bello University, Zaria, Nigeria.

 

Abstract

This paper aimed at demonstrating the application of water security assessment framework at national scale for sustainable national development. Water security dimensions in the literature were reviewed and identified as household water security, economic water security, urban water security, environmental water security and resilient water-related disaster security. It was discussed that national water security implied overall water security and it’s a composite measure of the indices of the stated five water security dimensions. Also, water security is central to all other form of security, including national security. It is recommended that nations should apply the water security assessment framework to assess their level of water security and hence national security for sustainable development.

Keywords:    Water security index, national security, sustainable development.

 

 

ASANTE INDIGENOUS KNOWLEDGE SYSTEMS: REPOSITORIES OF CONSERVATION ETHICS FOR GHANA’S BIODIVERSITY

 

DICKSON ADOM

Abstract

The indigenous knowledge systems of the Asantes handed down to them by their past, but active forebears carries a lot of weight in biodiversity conservation discussions. This is promulgated by the numerous conservation ethics hidden in the cultural and artistic practices of the people. Using the Asante Bekwai Traditional Area and its Protected Areas as a case study, the researcher accentuates the enormous conservation ethics in the Asante indigenous knowledge particularly cosmological beliefs, taboos and totems. The Data analysis spiral was implemented for the interpretation of the data accrued via focus group interviews and non- participant observations. The study revealed that the Asante indigenous knowledge systems were and is still instrumental in conserving the biodiversity resources by regulating the residents’ behaviours towards the biodiversity resources in the environment. The research contends that the conservation ethics of Asante indigenous knowledge transcend time and must be utilized in contemporary conservation strategies for biodiversity. The study advocates for a renaissance and factorization of Asante indigenous knowledge in various developmental projects in Ghana. It tasks developers of conservation strategies and projects in Ghana to tactfully synergize the Asante indigenous knowledge with the Western scientific knowledge to aid in conserving and arresting the deficiencies in Ghana’s biodiversity.

Abstract

In the contemporary global world, the up-shoot of graduate unemployment has become an all reaching concern. The stack reality is that for university graduates and other professionals, job competition and unemployment are becoming stiffer and tougher. The only genuine channel of restoration is entrepreneurship characterized by sustained job and wealth creation. Entrepreneurial Education into curriculum of tertiary education institutions is very important so as to equip graduates with entrepreneurial skills and abilities to make them become self reliant upon graduation. This paper examined the concepts of entrepreneurship, Entrepreneurship Education, objectives of Entrepreneurship Education, importance of Entrepreneurship Education, curriculum for entrepreneurship education, concept of unemployment, how tertiary institution graduates can develop entrepreneurial skills so as to become self reliant, and support of Government and Non- Governmental Organizations towards entrepreneurship development in Nigeria. It was recommended among others that; a new and workable education policy should be provided that favour the smooth implementation of Entrepreneurship Education at all levels of education; an Entrepreneurial Education Programme (EEP) should be formalized and integrated fully into the National Youth Service Corps (NYSC) scheme in the same spirit of weekly Community Development (CDS) of the NYSC. This if applied will in turn assist graduates with ideal job generation, creation and development ability.

Abstract

The study is focused on Performance Management Practices Among Small and Medium Scale Electronic Enterprises in Federal Capital Territory, Abuja, Nigeria. Two objectives and Two research questions guided the study. Mixed method of research design was adopted. The Population of the study comprises of Four Hundred and Twenty-one (421) Technical Personnel and One Hundred and Seventy-Nine (179) Managers of the major electronics SMEs in Abuja, Nigeria, this includes those located in Wuse, Kubwa, Garki, and Abuja Municipal Area. This amount to 74 enterprises that are registered with the Cooperate Affairs Commission (CAC). Simple random sampling technique was used to sample a total of Ninety-three (93) managers and one hundred and fifty-six (156) technical personnel for the study. The total sample population is, therefore, two hundred and forty-nine (249) respondents. Quantitative data was obtained from descriptive survey research design which involves the use of questionnaire while qualitative data was obtained from interviews of Managers and Technicians. Copies of the drafted instruments was validated by three experts two from the Department of Industrial and Technology Education, Federal University of Technology, Minna and one from SMEDAN. Data collected was analyzed using mean and standard deviation to answer the research questions and Z-test to test the hypothesis at 0.05 level of significance. It was thus found among others that; Employees are rarely train on the main purpose of performance management as well as to improve their capacity, employees are rarely involved in the planning process and that their work progress is seldom monitored. Thus, it was recommended that Electronic SMES owners should organize a series of workshops and training for all staff at all levels on the main purpose of the performance management system. Performance management is associated with the creation of a shared vision and aims of the organization and that Organizations should ensure active participation of staff in target setting for the performance management system at all department levels depending on job profiles, strengths of employees and resource availability.

Abstract

The intractability of several community conflicts across the different geo-political zones of  Nigeria have significantly hampered peace and overall social development within affected communities and the nation as a whole. Although conflicts have become part of our social existence that we must live with, nevertheless some of these conflicts which predate our amalgamation in 1914 still emerge with flames that seem uncontrollable. Giving the vitality of having strong communities as a way of emerging with a more stable and virile society of our dream, this paper therefore x-rays the causes and manifestation of community conflicts in Nigeria. As a way of capturing the severe consequences that community conflict poses to our collective development, this paper using secondary data analysis method shall discuss some significant community conflict as they have occurred in different communities in Nigeria and the violence that have erupted from them. Thus the need to proffer holistic approaches to addressing community conflicts as a way of remedying their negative consequences become very important. The paper therefore submits that some vital actions needs to be taken by Government and stakeholders to seriously pay attention to empowering communities to emerge with better resolves and actions that make them committed to threading pathways that lead to peace and transformation for their communities and the nation at large.

Abstract

Physical processes or activities are usually affected by enormous number of small external fluctuations whose resulting action would be natural to consider as random disturbance. The stability of dynamical systems with respect to random perturbations comes into the picture. It is paramount to investigate the role of random disturbance such as System perturbation on the qualitative characterization of two interacting dynamical systems. To achieve this, we have used ode45 and ode23 solvers to carry out the simulation under 0.1, 0.2 and 0.3 degrees of random noise to investigate the role of system perturbation on the stabilization of two interacting investors in the Niger Delta financial market. The results of this contribution are clearly presented and discussed in this paper. System perturbation on the qualitative characterization of two interacting dynamical systems is a formidable mathematical problem that requires sound numerical analysis reasoning. We have utilized two Matlab standard solvers for ordinary differential equations ODE45 and ODE23 under 0.1, 0.2 and 0.3 degrees of random noise to investigate the impact of system perturbation otherwise called random fluctuation on the stabilization of two interacting investors in the Niger Delta financial market. The results of this novel contribution are clearly presented and discussed in this paper.

Abstract

Video streaming has received a lot of attention from industry and academia due to an explosive growth of the internet and increasing demand for multimedia information on the web. However, the current best effort service does not guarantee effective utilization of bandwidth. One of the challenges which still remains a bottleneck to researchers is redundancy. Reducing or eliminating redundancies in live video streaming can significantly improve the Quality of Service (QoS). This paper presents the various types of redundancies that exist in videos and the ways in which they can be exploited so as to achieve optimal utilization of bandwidth. Thus, factors such as delay in delivery, frame loss and resolution degradation that adversely affect the QoS of video streaming can be reduced to the barest minimum even at low bandwidth.

Abstract

A multilayer dielectric optical notch filters design is estimated using TiO2 and SiO dielectric materials. Titanium dioxide (TiO2) is used as higher refractive index value (2.5) and Silicon dioxide (SiO2) as a lower refractive index layer (1.5). These filters are proposed for overpowering of powerful laser beams of light in the experimental research, in order to obtain very good signal-to-noise ratios in Raman laser spectroscopy applications. This is can be achieved by inserting a notch filter in between the within the beam of a design. In addition to spectroscopy, notch filters are also suitable in laser-based florescence instrumentation and biomedical laser systems. This Designed filter shows a very high quality with the transmission of more than 95% in 200 -1000 nm bandwidths. And a stop band region between 345-436 nm shows a transmission of 3% only with an optical density of greater than 3, which makes it a capable element to be used as a notch filter.

Abstract

The study evaluated the influence of globalisation on sustainable socio-economic development within the context of micro, small and medium-scale enterprises (MSMEs) in the contemporary Nigerian society. The central thrust of the study was to assess the influence of globalization on MSMEs’ growth vis-à-vis sustainable socio-economic development in the most populous African country. In the process, it was revealed that globalisation has served as the final conquest of capitalism all over the world despite its purported benefits to humanity. In addition, it was discovered that globalisation aimed at the transcendental homogenization of socio-economic theories across the globe has put to an end the hitherto order of marginalization and re-colonization in the 21st century Nigeria. It was recommended that Nigeria’s economy requires both micro–and–macroeconomic restructuring and realignment to survive the challenges of the twenty first century in a globalised world.

Abstract

Value Management (VM) has played a broad role in supporting effective decision making to construction projects, increased project performance and quality, balance project objectives, and manage community expectations in many countries around the world. But applicability of VM in Nigeria especially in Abuja construction industry has experienced a set back as compared with rest of the world. It is on this basis that the study examined the factors responsible for the set back with a view to recommending sustainable solutions. Therefore, the study sampled 235 professionals across the construction firms in Abuja through simple random sampling technique. The study employed descriptive (mean) and inferential (factor analysis) methods of data analysis. The  result revealed that through factor analysis technique, six most highly emphasized factors were identified which constituted about 65.690% variance in the original factors hindering value management application, which include technical and public policy factors,  professional negligence, non- complacency and management defects, human factor and inflexibility, lack of manpower and project focus, and poor knowledge. The study recommends that project managers should be proactive in addressing the aforementioned factors as they posed critical set back to value management implementation among Nigerian construction companies.

Abstract

Insurgency has for some time now, been a big threat to our lives in Nigeria. Poverty, corruption, unemployment and lack of proper education represent some of the major causes of insecurity in any society today. These issues have in many ways, affected national security and economic growth mostly in the Northern and Southern parts of the country. This study therefore identified strategies for combating insecurity via TVET with the aim of shaping the future of Nigerians for sustainable development. Two research questions were formulated to guide the study. Survey research design was employed for the study. The study was carried out in Kano state, Nigeria. The targeted population for the study was 233 (30 Air force personnel, 37 Armies, 25 Police men, 15 TVET teachers, 50 Entrepreneurs, 43 Industrialists and 33 Computer scientists) in Kano State. A purposive sampling technique was employed to arrive at the population for the study. A 49 strategic item questionnaire was the instrument used for data collection. Two hundred and thirty-three (233) copies of the questionnaire were administered to the respondents while one hundred and ninety-one (191) copies of the questionnaire were retrieved and analyzed using percentages (%), weighted mean (Ẋ) and standard deviation(SD). Cronbach Alpha reliability method was used to determine internal consistency of the instrument which yielded reliability coefficient of 0.82. Findings from the study revealed that the use of technology is a key enabler for counter-insurgency; the application of basic technology tools and solutions would go a long way in combating insurgency in the country. Also, education is an important prerequisite for a country’s social and sustainable development and TVET plays a special role in this regards amongst others. It was recommended amongst others the establishment of a functional National Security Database, for online access at every point of transaction, a technology driven database that enables the agency detect crime, forming a proactive employment and social security policies.

Abstract

The migration from rural to urban areas is an important part of the urbanization process in Damaturu town (Daura et al., 2006). This research focused on geographical studies of rural urban migration in Damaturu town. Data were collected from both primary and the secondary sources, Questionnaire was the instrument tool used during the data collection. Each set of questionnaire is composed/consist of two main sections (A and B). Section A contains demographic data of the respondents. While section B deals with question on causes and consequence of rural-urban migration in Damaturu town. Therefore, the simply random sampling technique was employed to select the respondents. A total number of 80 questionnaires have been used for data presentation, discussion and analysis from the four wards. Descriptive statistics like frequencies table no percentages, as well as inferential statistics line chi-square analysis is the tools applied for this research. Findings revealed that”. Majority of the migrants are young adult, while men migrates more than women. The young adults in the rural areas are migrate to urban area in order to improve their economic conditions. They (young adults) are pushed out from their origin (rural) because of the relative non-availability of employment opportunities. The research also found that the desire for gainful employment is the ultimate factor behind rural-urban migration. However other less compelling motivator such as the desire to enjoy the social amenities service likes electricity, good roads, and good drinking water.

Abstract

It has been observed by several authors that students entering teacher education programs have preconceptions about teaching Mathematics based on their prior experiences as students. These experiences as it were create the intending teachers self-efficacy and belief about Mathematics which will eventually have a powerful impact on the practice of teaching, learning and over all achievement of their students in Mathematics. Therefore, this study is aimed at investigating self-efficacy, locus of control, self-assessment of memory ability and study habit as a predictor of pre-service teachers’ achievement in Mathematics. The design employed in this study is an ex-post facto type. The sample consists of 147 pre-services teachers purposively selected from two colleges of education within Oyo State. Four standardized instrument were used to collect data on Mathematics teaching efficacy belief, locus of control, memory self-efficacy and study habits. The reliability coefficients of each instrument used are stated thus: 0.69, 0.86, 0.90 and 0.88. Three research questions were proposed in the study and the data collected were analyzed with multiple regression. The study revealed that positive significant correlation (.427) exists between achievement in Mathematics and Locus of Control while a negative correlation (.-467) exists between Achievement in Mathematics and Study Habit. Similarly it was observed that no significant correlation exist between self-efficacy, self assessment of memory ability and achievement in Mathematics respectively. Furthermore the regression analysis of the data revealed that the four predictor variables contributed 36.90% to achievement in Mathematics. The analysis of variance also yielded an F-ratio of 20.764 which was significant at 0.05 levels. Hence they are good predictors of achievement in Mathematics. In addition, the study also revealed the relative contributions of each of the independent variables to the prediction of achievement in Mathematics thus; self-efficacy (b=.146), Locus of control (b=.345), Study habit (b=.-458) and each was significant at 0.05 level, while self assessment of memory ability (b=.018) was not significant. Implications for pre-service Mathematics teacher education were also discussed.

Abstract

Agricultural biomass residues are sources of renewable energy and sustainable biofuels which can contribute significantly to mitigate the effect of greenhouse gas (GHG) emissions if properly managed and utilized. However, biomass in its natural form is bulky, loosed and dispersed. Briquetting is therefore employed to improve the qualities of the residues such as density, stability, durability and heating or calorific value. Controlling densification system variables can be important to achieving the desired density, durability and quality. In this study, the effect of some densification parameters, namely; particle size, binder ratio and compaction pressure on the physicomechanical (maximum density, relaxed density, density ratio, compaction ratio and durability of sawdust briquettes was investigated. The results of the physicomechanical characteristics of the sawdust briquettes obtained compared favourably well with those obtained by previous researchers. However, not all the densification variables had significant effect (p<0.05) on the physicomechanical characteristics of the sawdust briquettes. This implied that some of the densification (predictor) variables contributed more than others on the predictor variables (physicomechanical characteristics).

Abstract

Transportation systems play a vital role in urbanisation, mobility, and economic growth of societies, regions, nations, and even continents. Transportation of people and goods from one location to another is necessary. No country will thrive if it lacks adequate, well maintained and managed transportation facilities. As such, provision of efficient, environmentally friendly and sustainable transportation system/facilities are considered as the index of social, economic and commercial development. However, with the growing population in major cities of the world, there is also an increase in traffic congestion, traffic accidents, and environmental pollutions. These problems have generated so much concern among the key players in the transportation sector. Provision of new transportation facilities that may solve some of the problems require huge capital investment. Therefore, it has become imperative to manage transportation facilities right from the planning stages to the expected service live of the facilities and also maintain the existing ones.

Abstract

Over the years, the professional accountant writes up books, balances books, prepares final accounts, conduct investigations, audit accounts and prepare tax returns among many other services. These accounting services by the accountants were traditionally based on clerical reliance systems without any interactions with the computer systems. In order to facilitate prompt and accurate delivery of appropriate services to business enterprises, accounting firms require dynamism to keep abreast of development in their profession because it is assumed that the accounting industry is far behind in adopting new technologies. Therefore, this study investigated the impact of technological innovation on the performance of accounting firms in Nigeria. A descriptive survey research designed method was adopted. Data were collected through a survey, using a structured questionnaire validated by experts and yielding 0.771cronbach alpha. The top ten accounting firms in Nigeria were selected for the study and a non-probabilistic sample included 200 respondents of which 102 copies of the structured questionnaire were completed and returned. The data analysis was carried out to determine the Pearson product moment correlation coefficient (r) and the coefficient of determination (R2) of the variables with the aid of SPSS. Findings revealed that technological innovation significantly affects performance of the accounting firms in Nigeria. It was concluded that IT strengthened and improved the quality and reporting standards of the Nigerian accounting firms while it was recommended that accounting firms should be more efficient and timely in their responsibilities with a view to meet up with the needs of their clients.

Abstract

Roads dominate the transport sector in most African countries, carrying 80 to 90 percent of passenger and freight traffic. Moreover, they are the only means of access to most rural communities. This dominance is achieved even though the density of the region’s network is lower, both per person and per square kilometer of land area, than that of other world regions. The condition of the road system is also poor by international standards. Africa has huge infrastructure gaps due to tight government funding and scarce resources hence the way forward is to explore the private sector investment through PPP. In these difficult circumstances, the provision of secure funding for road maintenance and efficient implementation are critical to the effectiveness of the sector and to identify specific capacity constraints that have hindered the private sector’s participation in road infrastructure financing. The transport sector in sub-Sahara Africa requires spending of approximately $18 billion a year, half for maintenance, to build sufficient regional, national, rural, and urban road connectivity. Several literatures were review in a bid to Annalise and suggest possible alternatives to the burden and shortfall of private involvement in road infrastructure development in Sub-Sahara Africa. Today PPPs have emerged as an important mode of financing infrastructure projects in several developing countries. PPPs are “cooperative arrangements between governments and multinational corporations that are created to finance, construct and manage infrastructural projects.

Abstract

The Thermal decomposition behaviours of poly (vinyl pyrrolidone) (PVP) was successfully studied using thermogravimetric analysis in the range of 30–1000 °C under different atmospheric condition of nitrogen, oxygen, air and finally at normal condition without passing any gas. Under all the conditions, it was found that the main decomposing agent in PVP is the volatile product from the ester group and the C–C in the polymeric chain. The decomposition under nitrogen atmosphere offers the lowest temperature of 500 °C, while the highest decomposition temperature of 625 °C was observed when the analysis was conducted under normal atmospheric condition. The decomposition under O2 and air atmosphere recorded final stage at 514 and 568 °C, respectively. The amorphous structure of the PVP was confirmed by the XRD analysis while the FT–IR and Raman analyses were used to confirm the presence of several polymer bonds in the PVP.

Abstract

The paper clearly spelled out the meaning of the word “Dhimmah,” which is an Arabic word to mean the ability to acquire rights and obligations by a mukallaf (the subject of law) which is not just left without conditions or hindrance it also stated the life circle of any human being is categorized in to four. From the time an embryo is conceived in it’s mother’s womb to it’s delivery, from delivery to Tamyiz (which is seven years according to Islamic Jurists), from Tamyiz to maturity and from maturity until death. Therefore after attaining legal capacity, sometimes ability of certain people to engage in contractual relationship is curtailed. The factors include but not limited to natural circumstances and man affected or acquired causes like sleeping, infancy, in coercion/duress, mistake and ignorance on the other side.

Key Words:

  • The life circles of human beings are divided into four (4) stages.
  • In the first three (3) stages one is not criminally liable, but liable in tort.
  • Upon reaching the fourth stage, one is both criminally responsible and the liable in tort.
  • There are two (2) factors that affect the legal capacity even after maturity.
  • Natural circumstances and man acquired are two (2) factors that affect the legal capacity.

Research Methodology:

The methodology followed in this research work is through having research in many Islamic books and manuscripts.

Department of Science Laboratory Technology Federal Polytechnic Bauchi, Bauchi State Nigeria.

 

Abstract

Optical coating is one of the process of deposition one or more thin films of materials of alternative layers on optical components such as mirrors or lenses, which changes the direction in which light in the components reflect or transmit. Objective: This paper aims to study the effect of increasing number of layers in optical filter design using the optical matrix approach method. MATLAB program version 8.1 was used to model the designs. Result: The reflection of a glass substrate of refractive index = 1.5 was enhanced by adding successive dielectric layers of alternating high refractive index ( = 4.7) from MoS2 material and low refractive index ( = 3.2) from Si material respectively. The reflectance increased as the number of layers increasing or vice versa. Therefore, the maximum reflectance is achieved by adding a successful layer depending on the design (glass 12|LH|air) the reflectance and transmittance. Conclusions: The reflectance and transmittance of the glass increased by increasing the number of layers and the high reflectance and transmittance achieved by putting the layer of high refractive index as outer layer. It is observed that the bandwidth of the reflectance and transmittance is affected by increasing the number of layers.

Abstract

A topologically conjugate map that is equivalent to the well known logistic map  with  and  is constructed. This constructed map’s domain is defined to be the integer domain [0, 2n). This domain has a one to one correspondence to the points in the interval [0, 1] with  n-bits precision. The topological conjugacy of the two maps and the dynamics of the constructed map were found to define the same dynamics as that of the logistic map with very similar lyapunov exponents. With a view to be applied in cryptography as a Pseudo-Random number generator (PRNG), the complexity of the constructed map as a source of randomness is determined using both the Permutation entropy (PE) and the Lempel-Ziv (LZ-76) complexity measures, and the results are compared with numerical simulations.

Abstract

Various theories of genetic, biological, neurological, evolution any and environmental factors attributed to handedness have been x-rayed in this paper. It also attempted to highlight types of handedness and the use of dominant hand in some selected cultures across the globe, particularly, in the United States of America, Europe, Asia, Caribean and African countries. The paper further presented stigmatization attached to dominant hand, most especially, the left –handedness. Psychological implications of stigmatizing the left handedness have also been highlighted. Conclusion and recommendations were proffered for necessary adjustment and adaptation. In this premise, parents were advised to train their children towards the use of right hand, particularly, when eating or giving something to someone during childhood so as to inculcate the cultural value of the society. However, if this strategy fails, parents should encourage their children towards the use of dominant hand that is more convenient for their children, so as to make use of their potentials to the fullest, and to attain the hallmarks of noble personalities in life.

Keywords:     Theories, Handedness, Dominant Hand, Stigmatization, Psychological implications.
