- ItemOpen AccessAbout Crawling Scheduling Problems.(CEUR Workshop Proceedings, 2017-09) Pechnikov, A.A; Chernobrovkin, D.I; Nwohiri, A.MThis paper investigates the task of scheduling jobs across several servers in a software system similar to the Enterprise Desktop Grid. One of the features of this system is that it has a specific area of action –collects outbound hyperlinks for a given set of websites. The target set is scanned continuously (and regularly) at certain time intervals. Data obtained from previous scans are used to construct the next scanning task for the purpose of enhancing efficiency (shortening the scanning time in this case). A mathematical model for minimizing the scanning time for a batch mode is constructed; an approximate algorithm for the solution of the model is proposed. A series of experiments are carried out in a real software system. The results obtained from the experiments enabled to compare the proposed batch mode with the known round robin mode. This revealed the advantagesand disadvantages of the batch mode
- ItemOpen AccessAbstracts Of International Conference And ExhibitionN On Obesity & Weight Management(2012-12-05) Bolajoko, A.; Ogbo, P.UObesity and type 2 diabetes mellitus constitute major public health issues in modern societies worldwide. They have been linked in several ways. Obesity is involved in the pathologic process that culminates in the development of type 2 diabetes. The aim of this study was to assess the frequency of obesity in known type 2 diabetic patients and also to determine the presence of comorbidities associated with these two conditions. The study was carried out at Lagos University Teaching hospital and was designed as a retrospective review of the medical records of type 2 diabetic patients undergoing treatment at the Hospital for the year 2011. Seventy six case notes were accessed. Out of the 76 case notes only 63 were used in analysis. Assessment included weight, height, age, sex, comorbidities present, genetic factors and duration of diabetes. Forty six patients (73%) were either obese (34.9%) or overweight (38.1%) while 23.8% were of normal weight. The majority of diabetic patients were in the age groups 50-59 and 60-69. Average BMI for obese and overweight patients were 32.73+ 3.73 and 26.61+ 1.88 respectfully. Comorbidities such as hypertension, dyslipidaemia, retinopathy, neuropathy, renal impairment and ulcer were found present. The study revealed high prevalence of obesity/overweight among the diabetic patients. Hypertension and retinopathy were common in these patients. Health care professionals should encourage patients to adopt preventive measures or life style that will lead to weight loss as weight loss by 5% is enough to reduce the incidence of comorbidities which affect mortality and morbidity.
- ItemOpen AccessAbuse of Office and Neglect of Duty: Ethical Issues in Staff-Student Relations.(2003-07) Bammeke, FThis paper argues that a close analysis of staff-student relations within institutions of higher learning shows that rather than both parties upholding the ethics guiding their institutions, or justifying the confidence reposed in them, some of them exhibit behaviour capable of undermining the merit system and questioning the rationale of the institutions' claim to the production and preservation of knowledge. The paper suggests that a commitment to core ethical values can help individuals in their relationship with others and ultimately help institutions to uphold values which are central to their continued relevance.
- ItemOpen AccessAcademia-Government- Industry Relations: A Case for the Engineering Discipline in Nigeria(2002-09-23) Ajayi, TNigeria has for long been a developing nation without much progress. An observation of some of the countries of the world reveals a strong interplay between the quality of engineering education and the technological advancement of such country. This paper succinctly examines the practice of engineering education in Nigeria and shows that not much attention is given to the various components that make for quality engineering education. There is the need for academia - the trainer of the manpower for technological advancement, and industry - the user of such manpower, to come together in an interactive partnership. It is the synergy achieved by such interaction that technologically advances a country. The government has been identified as the facilitator of such a partnership and the engineering professional body as the umbrella under which all three - academia, government and industry can meet and strategize.

- ItemOpen AccessAn adaptive sampling procedure for estimating heavy metal pollutants of ground water from soil(2008) Adeleke, I. A; Okafor, R; Esan, E. O; Opara, A. I; Olayinka, O. K; Oyeyiola, A. OWe consider an adaptive cluster sampling procedure for assessment of contaminant risk to ground water from soil at Owode-Onirin, Lagos, Nigeria. This method provides a more efficient way of sampling sparse but highly clustered population, and exploits the advantage of spatial clustered population to yield more efficient estimates of the concentrations of heavy metals pollutants of ground water from soil. A model-assisted estimation approach that incorporates models into the design-based estimation frame work was considered.
- ItemOpen AccessAdministrators Leadership Skills and Employees Job Engagement in Tertiary Educational Institutions in Ogun State Nigeria(AT THE FLORA GRAND HOTEL, DEIRA, DUBAI, UNITED ARAB EMIRATES, 2017-10) Adekunle, A.AThe study examined the influence of administrators' leadership skills on employees' job engagement in tertiary educational institutions is Ogun State, Nigeria. The study was guided by three research questions. A descriptive survey research design was adopted for the study. The sample comprises 415 employees (academic and non-teaching staff) selected from six out of the 12 public tertiary institutions in Ogun State, Nigeria, using multi-stage sampling technique. A researcher-designed 30 item 4 point modified Likert rating scale instrument entitled "Administrators Leadership Skills and Employees' Job Engagement Questionnaire" (ALSEJEQ) was used for data collection. The instrument was subjected to reliability test using the Crombach Alpha method and a reliability coefficient of 0.89 was obtained. Data obtained were analysed statistically using multiple Regression Analysis to answer all the research questions at 0.05 level of significance. The results show that, though low, the overall model of the three administrators' leadership skills indicators significantly predicted employees' job engagement in tertiary educational institutions in Ogun State (F(3, 411) = 47.195, P < 0.05) ; that, though low, the overall model of the administrators' leadership skills indicators significantly predicted employees' job engagement in tertiary educational institutions in Ogun State (F(3, 411) = 47.195, P < 0.05); and that although, administrators' analytical skills significantly contributed to the model, the contribution was negative ~ = - .284, t (411) = -3.028, P < 0.05. The third variable, administrators' conceptual skills did not significantly contribute to the model ~ = -.048, t (411) = -.496, P = .620. It was therefore recommended that appointment of Administrators of tertiary educational institutions should be hinged on evidence of haven undergone training at the National Institute for Educational Planning and Administration (NIEPA, Nigeria), and that serving institutional Administrators should as a matter of policy be required to engage in Mandatory Continuing Professional Education which serves as a refresher course from time to time so as to be kept abreast of contemporary theories and practices in educational management.

- ItemOpen AccessAfrica within Global Cities: What do we know and how to proceed?(2018) Odekunle, D.M; Alabi, A.OIncreasing globalization, unprecedented urbanisation, environmental consciousness and technology development has redirected global cities' focus towards strategic and smart solutions to solve issues changing city dynamics through a smart city agenda, African cities included. The smart city agenda has been globally debated via varying perspectives but most of the concept's ideology has been limited to the diffusion of technology; excluding social, human, economic, environmental capital and city networks that determine city progress and smartness. Also, despite Africa's incessant dysfunctional land and housing systems,inadequate basic services and infrastructure and poor environmental performances; less research exist in the continent to understand this concept, its application and the continent's position amongst world smart cities. This paper investigates the concept of smart cities within the spectrum of these identified gaps. The research begins by providing an array of relevant literature on smart city. It then assesses global smart cities with specific attention on the position of African cities amongst these cities. The research methodology included a quantitative data analysis based on an ordered probit regression model to examine the relationship between a city's characteristics and its smartness. The study revealed that for a city, especially African cities to achieve a high level of smartness and prosperity, the city needs to have a long term and global vision beyond the domain of leT. The study concludes by critically re-examining development policy agendas and integrating elements of a smart city into a particular city's vision, policy makers in Africa will discover requisite information on attaining smart, sustainable and integrated development in their cities.

- ItemOpen AccessAfrican Syntactic Structure not a Function of Cartesian Logique. A Study of Malinke Interference in the Works of Ahmadou Kourouma(2004-04-01) Ariole, V.CAhmadou Kourouma is an Ivoirien writer of Malinke origin. He has written FOUR novels, THREE children novel and a drama. His French is acclaimed to be original and reflects a lot of Malinke idiolects. His syntactic construct has both French and Malinke features. Using functionalist approach, we analysed his works for translation purposes. We found out that beyond ordinary "significant" his constructs demand the consideration of "significant superieur" or super significant that is, meaning derived from syntagmatic chain of more than a word. For example: "il est fini", "Les solei Is des independances' e.t.c. are syntactic constructs that are very specific to the Malinke though they conform to French structure. His works thrive also in the recognition of nucleus elements as against virtual identities or features. In all, we established the fact that his works or each of the novels has three in-built components, universal admissible component, alternative admissible component and, component peculiar to the Malinke and calls for Malinke sensitivity for its understanding and appreciation. His works debunk partially a universal grammar as proposed by Chornsky but align totally with functionalist approach of "noyau" (nucleus elements of syntactic construct
- ItemOpen AccessAfrican Theory of Forces and the Extended Family Relations:a Deconstruction(1999-09-13) Unah, J.IAfrican ontology, for the most part, has been premised on an ancient theory of forces hierarchicized in an inseparable continuum. The basic assumption that forces interact, intermingle and interpenetrate one another informed the extended family relations which stresses the brotherhood of man and the communion of souls from which architects of African societies in the post-colonial era constructed primitive socialism(s) and primitive capitalism( s). The purist school of thought in African philosophy had eulogized every intellectual attempt to relive naive experience from the African past which strengthened the communality and the extended family relations. As we move into the new millennium with most of black Africa embroiled in social, economic and political turmoil, the hierarchicized theory of forces and the resultant extended family system are overdue for a phenomenological baptism of fire. What is envisaged in such a baptism of fire is the destruction of ancient African ontology with a view to allowing the transcendental ego or, rather, the intersubjective ego to emerge. The net result would be that the existent individual is assisted to extricate itself from petty, partisan, parochial, considerations to ascend the pedestal of global humanism. Only on such a pedestal (global humanism) could African societies attain authentic egalitarianism.
- ItemOpen AccessAge and Driving Experience as Predictors of Driving Error among Work-related Drivers in Lagos Metropolis(2014-11-29) Malomo, B.IThe loss of lives from road traffic crashes is still occurring at an unacceptable level on Nigerian roads. Observers and commentators have in several cases implicated driver error as the major factor in traffic crashes. Furthermore, some demographic variables have been cited in traffic literature as predictors of driving error among drivers. However, this has not been empirically determined in Nigeria. Therefore this study examines age and driving experience of drivers as predictors of driving errors on Nigerian roads. Utilising ex post facto and survey research designs, responses were obtained from 547 drivers selected using a multistage sampling technique in Lagos metropolis who responded to self-report measures of driving errors. Findings reveal that age and driving experience did not significantly and independently predict driving error rates. However, age and driving experience significantly and jointly predicted driving error (β = 16.84; df = 544, F = 1.340, p < .005) rates of participants. The results are indicative of policy measures that will be relevant to the reduction of road accidents. Recommendations are offered to corporate and private entities that require the services of drivers who are less prone to driving errors.

- ItemOpen AccessAn Alternative Approach for Computing the Union and Intersection of Fuzzy Sets: A Basis for Design of Robust Fuzzy Controllers(2008-02-20) Olunloyo, V.O.S; Ajofoyinbo, A.M; Badiru, A.BThe capability of fuzzy sets to express gradual transition from membership to non-membership and vice versa has broad utility. The overlap between two or more adjoining fuzzy sets create very important fuzzy “patch” that deserves special attention. In the existing literature, Zadeh, Mamdani and TagakiSugeno have established that the Min- and Max- operators can effectively be used for fuzzy interpolative inference. But what has not been done is to define an explicit expression for determining membership function in the overlap region. This paper addresses that concern, as it proposes an alternative approach to determination of membership function based on the Fourier series representation of the envelope of the fuzzy “patch”.
- ItemOpen AccessAnalysis of a Phonological Variation in Oraukwu Dialect of Igbo: A Case of the Phoneme /l/ for /r/(Faculty of Arts. University of Lagos, 2005-05) Okafor, E. E.This paper is an analysis of the use of the phoneme IV for III in Oraukwu dialect of Igbo. It takes into cognizance the phonetic - phonological variability of ordinary speech. Oraukwu speakers virtually do not use the phoneme /l/ in their speech. Rather, the use phoneme I I where the phoneme /r/ should occur. For instance, /Oraukwu/ is spelt /Oraukwu/ but it is called /Olaukwu/ by Oraukwu community. Quite important to this work is the fact that the researcher interacted with a number of people that make up the various villages in Oraukwu. Among the people interviewed are the older living generation ranges from age 51-80, who have lived a greater proportion of their lives in Oraukwu, and therefore have less formal education. They also have not as heavily influenced by cross-linguistic/cultural contacts and have not worked in highly hierarchical organisation. On the other hand. she interviewed lite younger living generation. ranges from age 20- 50, who have lived a lesser proportion of' their lives in Oraukwu, precisely from childhood to adolescent. They have more formal education both in Oraukwu and in cities. They also have more cross-linguistic/cultural contact, and are working in highly formal hierarchical organization. To determine the use of the phoneme /l/ for /r/ in Oraukwu community, oral interview was administered to them. It was discovered that Oraukwu speakers use the phoneme /l/ for /r/ in their speech. but in writing they use the phoneme /r/. The paper however. adduces all analytical explanation based on. phonetic-phonological reasons for the occurrence of both phenomena. The work starts with the introduction: the Igbo language, a brief history of Oraukwu dialect; and the concept of phonology. It examines the phonemes /l/ and /r/ as phonetic and phonological segments, as well as their feature matrixes. It finally analyses data collected [rom Oraukwu speakers and draws the logical conclusion.
