Influence Of Automated Cataloguing System On Manual Cataloguing System In The Library: A Case Study Of Selected Academic Libraries In South-West, Nigeria

This study examied the automation of cataloguing and classification practices in academic libraries in South-West Nigerian and what effect the automated cata/o~uin~ systme has on manual catalo~uin~ in the the libraries. The stifdv population 1 comprised II 0 library professional and paraprofessional personnel working in the cataloguing section oft he {en jetJeral and state university libraries in South-West Nigeria. Total enumeration technique was used to randomly se,fect the study population for this study. Data for this study was collected using questionnaire. A 5-point Likert scale were' used with 1-5 representing 'strongly agree', 'agree', 'undecided', . 'disagree' and 'strongly disagree ' respectively, ·to e/idit information .from the respondents. A total of II 0 copies of the questionnaires were distributed to the respondents. 85 copies of the questionnaires were retrieved and valid for analysis. Data were analysed using charts, table, frequencies, percentage, mean and standard deviation. The result of the study find out that automation is. changing positively the way bibliographic details are being created and displayed. Cataloguing is now quicker with the automated system and that automated system is preferred to the manoa/ system. The study highlighted various benefits of cataloguing automation such as automation · improve inter-personal relationship, saves time, easy feedback/rom library user, etc.The study recommends that libraries should not be satisfied with the little benefits derived from the partial automation of the cataloguing and other sections of the libraries but should fully automate the systems and continuously upgrade the automated systems especially as technology unfol

Fabrication characteristics and mechanical behaviour of rice husk ash – Alumina reinforced Al-Mg-Si alloy matrix hybrid composites

AbstractThe fabrication characteristics and mechanical behaviour of Al-Mg-Si alloy matrix composites reinforced with alumina (Al2O3) and rice husk ash (RHA, an agro-waste) was investigated. This was aimed at assessing the viability of developing high performance Al matrix composites at reduced cost. Al2O3 particulates added with 0, 2, 3, and 4 wt% RHA were utilized to prepare 10 wt% of the reinforcing phase with Al-Mg-Si alloy as matrix using two-step stir casting method. Density measurement, estimated percent porosity, tensile testing, micro-hardness measurement, optical microscopy, and SEM examination were used to characterize the composites produced. The results show that the less dense Al-Mg-Si/RHA/Al2O3 hybrid composites have estimated percent porosity levels as low as the single Al2O3 reinforced grade (< 2.3% porosity). The hardness of the hybrid composites decreases slightly with increase in RHA content with a maximum reduction of less than 11% observed for the Al-4 wt% RHA-6wt% Al2O3 composition (in comparison with the Al-10 wt% Al2O3 single reinforced composition). Tensile strength reductions of 8% and 13%, and specific strengths which were 3.56% and 7.7% lower were respectively observed for the 3 wt% and 4 wt% RHA containing hybrid composites. The specific strength, percent elongation and fracture toughness of the 2 wt% RHA containing hybrid composite was however, higher than that of the single Al2O3 reinforced and other hybrid composite compositions worked on. RHA thus has great promise to serve as a complementing reinforcement for the development of low cost-high performance aluminum hybrid composites

Evaluation of physical characteristics of chevon as affected by post-mortem carcass dressing and freezing preservation

This study was conducted to investigate the effects of post-mortem dressing methods and freezing preservation on the physical characteristics of chevon. Twenty-seven Red-Sokoto male goats between 10 and 12 months of age weighing 18–20 kg were purchased, stabilized and slaughtered. The carcasses were randomly allotted to three post-mortem dressing procedures (scalding, skinning and singeing) and meat from thigh cuts was frozen for 0, 7, 14 and 21 days. Meat samples were excised each day after thawing for physical analysis and data collected were subjected to analysis of variance (ANOVA) in a completely randomized design experiment with 3x4 factorial arrangement. The significant means were separated with the Duncan multiple range test at p&lt;0.05. The results showed that the post-mortem dressing methods and freezing affected Red-Sokoto chevon significantly with the singeing method exerting the highest detrimental effects on physical attributes of meat with the exception of color, yield and pH, while the skinning method exerted the least detrimental effects. Also, cold, cooking and drip losses as well as thermal shortening, cold shortening and pH values increased between the 14th and 21st day, while color, yield, water holding capacity, texture and shear force values decreased across the three treatments during freezing periods. The effects were more significant in singed and scalded meat than in skinned chevon. It was recommended, therefore, that skinning method be encouraged if meat from Red-sokoto male goats is to be frozen and the period of freezing be limited to 14 days for wholesome meat

Assessment of Rural – Urban Migration in South – Western Nigeria

The study examines rural urban migration in south – western Nigeria. Population of the study is the rural households of southwestern Nigeria Multi Stage random sampling technique was used to select two out of the six states that make up the south – western Nigeria. Five Local Government Areas were also randomly selected from each of the state while one rural community was randomly selected from each of the Local Government Area making a total of ten communities used for the survey. Twelve respondents were selected from each community making a total of one hundred and twenty (120) respondents for the study. Data collected were analyzed using Descriptive Analytical tools while Chi-square were used to establish relationship that existed between respondents’ socio – economic characteristics and their annual income among others. Findings revealed that there are more male (62.2%) than the female (37.8%) migrants, that income was one of the major determinant of migration (23.300, p = 0.000). Also majority migrated as a result of lack of social amenities such as health facilities (69.2%), and job opportunities (65.0%) coupled with higher standard of living in urban areas (74.2%) than rural areas

Effect of Information Utilization on Decision-Making by Senior Managers : A Case Study

organisations for competitive edge. While many Nigerian government establishments have continued to invest on information systems and technologies little is known on the effect of such systems on the organisation. The study therefore, investigated the effects of information utilisation on decision-making of senior managers in two federal government establishments in Abuja, Nigeria. Descriptive survey research design was used for the study; the questionnaire was the instrument used while the managers in two selected federal government establishments in Abuja constituted the population for the study and the simple random sampling technique was made use of. Out of the two hundred (200) copies of questionnaire distributed in the two federal government establishments, one hundred and fifty-seven (78.5%) were returned with valid responses. Data were analyzed using descriptive statistic, specifically frequencies, mean, cross tabulation as well as percentages and standard deviation. The findings revealed that 115 (73.2%) use information at least weekly, administrative information and planning, monitoring and evaluation information were the most frequently information utilized by managers for decision making. 148(94.3%) agreed that information enhances effective decision-making, 118(75.1%) managers agreed that the major challenge was the scarcity of factual information The on-site assessment revealed that a very high number of senior managers do not visit the library, one of the establishments did not have a library as at when this study was carried out. On the overall, it was revealed that the managers faced challenges in the use of information to support decision making. The study recommends that government/organization should establish an information center and stock it with relevant resources in all Federal Government Establishments to equip the senior managers and all staff with quality information to enhance their decision making effectivenes

Abstract

Information sources for decision making by senior managers in two Federal Government parastatals in Nigeria

This paper focused on information sources used for decision making by managers in the National Sport Commission (NSC) and Corporate Affair Commission (CAC) Abuja, Nigeria. Information is widely believed as the raw materials upon which decisions are made. It is also a critical resource that affects individual as well as organization. Senior managers shoulder the responsibility of formulating policies that organization needs for the smooth running of their individuals establishments. The quality of decision made is also dependent on how current the sources of information utilized to make it. Much of policies formulated for national development have little or no positive impact today, as a result of sources of information consulted to make such a decision. The descriptive survey design was used for the study. Simple random sampling technique was used to select the population for the study. The study found that 53.5% of the sampled population falls between the ages of 41-50. Male respondents were more than their female counterpart. The larger percentages of the respondents are degree holder. The sources of information mostly used for decision making by the senior managers includes reports, minutes of meetings, internal memoranda, policies files among many others, while newsletters, library and information centers, textbooks, official bulletins and journals are sparingly consulted. Senior manger also uses information to carry out day-to-day routines, for decision making effectiveness, appointments and promotion issues and to stay up-to-date with current affair issues. It was also noted that senior manager are not enjoying library services in their various establishments. The study recommends that library services be improved upon in Federal parastatal
