    An Appraisal of GSM Telecommunications Services Delivery in Lagos and Oyo States of Nigeria
    (2015-03-17) Abdul – Hameed, Taofeek Adekunle
    The study appraised the quality, volume and the capacity of the telecommunications facilities of the GSM Service Providers in Lagos and Oyo States of Nigeria. This was with a view to developing strategies for improved service delivery in the industry. The study covered all areas of operation of MTN, CELTEL, GLOBACOM and M - TEL in Lagos and Oyo states. Data were collected on Key Performance Indicators (KPIs) such as conversational voice quality, call setup success ratio, call retention ratio, and short message service (SMS) transmission success ratio using questionnaires. International Telecommunications Union (ITU) specifications were used for evaluation. One thousand (1,000) respondents (500 MTN; 250 CELTEL; 150 GLOBACOM and 100 M - TEL subscribers) from each state were randomly selected. Secondary data such as type and location of Base Transceiver Stations (BTS) and other transmitting and receiving facilities were collected from the Service Providers' websites. In addition, physical inspection of the facilities was made. Data were analysed using descriptive statistics. The study showed that 100% of the BTS of all the Providers used Macro Cell Antennae with no one using Micro, Pico and Umbrella Cell types; making the mobility management operations of the GSM Service Providers abysmally poor. Also, about 60% of the Macro Cell Antennaes were concentrated in the residential areas. The results showed that CELTEL had the best score in Oyo State (1.96), and M-TEL in Lagos State (2.55) for voice quality measured on a 5-point mean opinion scale. Furthermore, the interconnectivity call setup success ratio was low (CELTEL = 17.1% in Oyo State; GLOBACOM = 19.2 % in Lagos State) as against the international minimum standard of 98% of attempted calls. However, the interconnectivity call setup success ratio was fair (CELTEL = 36.5% in Oyo State; 47.7 % in Lagos State) compared to minimum standard of 99% of attempted calls. The call retention ratio was above average (CELTEL = 66.6% in Oyo State; 69.3 % in Lagos State) compared to the minimum standard of 98% of successful setups. Furthermore, the short message services delivery efficiency was the best with CELTEL having 72.1% and 74.3 % in Oyo and Lagos States, respectively, as against the minimum standard of 98 % of attempted transmissions. The number of subscribers for MTN increased by 1,582 % between year 2001 and 2006 without a matching increase in the facilities provided. The forecast results also showed the increment to be 6,125 % by the end of 2011. The study concluded that in both states, the quality of voice and message services provided were below International Standards due to inadequate capacity of the telecommunication facilities to match the growth in service demand and inappropriate blend of cell antennaes.

    The Impact of Technological Innovative Entrepreneurial Development Programmes on the Performance of Small Scale Businesses in Ondo State, Nigeria
    (2015-08-25) Aribaba, Foluso Olugbenga
    This study identified the technological development programmes available to entrepreneurs in Ondo state and evaluated the effectiveness of these programmes on the performance of small - scale businesses in the state. The study also assessed the constraints of implementing the programmes. This was with a view to improving on the quality of the entrepreneurial development programmes and fast tracking the development of small scale businesses in the state. One hundred and sixty of 200 small-scale industrialists on the register of the National Association of Small Scale Industrialists (NASSI), Ondo State Chapter, were randomly selected for this study. Data were collected from 95 firms that had participated in the entrepreneurship development programmes and 65 firms that had not participated in the entrepreneurship development programmes through the use of questionnaire, interview schedule and personal observation. The instruments elicited information on the socio-demographic background of the entrepreneurs, level of awareness of the entrepreneurs about the entrepreneurial development programmes and the performances of their businesses. Descriptive statistics were employed for data analysis. The results of the study showed that six entrepreneurship development programmes were operational in Ondo state were: (1) work for yourself programme, (2) start your business programme, (3) improve your business programme, (4) the EMPRETEC entrepreneurship development programme, (5) technological business incubator programme and (6) work improvement for small enterprises programme. The entrepreneurship development programmes were rated average in terms of content ( X = 3.59), quality of trainers ( X = 3.69), cost in terms of benefit and affordability (X= 3.46) and location (X= 3.34). The results also showed monthly value added of N232,052.64 growth rate of 0.02% and rate of networking of 5.90% for proprietors who participated in the programmes. Those who did not participate had monthly value added of N159,333.34, rate of growth of 0.01% and rate of networking of 0.02%. In addition, the respondents regarded accessibility to the programmes (28.10%) and finance (24.20%) as the major limiting factors on the implementation of the programmes, and lack of awareness of the programmes (3.80%) as the least factor militating against the implementation of the entrepreneurship development programmes. In conclusion, the study showed that in general, participation in technological innovative entrepreneurial development programmes had a positive impact on the performance of small-scale businesses in Ondo state.

    An Assessment of the Transfer and Commercialization of Research and Development Results from Research Institutes in Southwestern Nigeria
    (2015-09-23) Adeyemo, Felicia Solayide
    The study assessed the extent of utilization of research and development (R&D) results in research institutes in southwestern Nigeria. It also examined the methods of transferring R&D results and the factors affecting the commercialization of R&D results. This was with a view to improving utilization of R&D results in Nigeria. Primary data were collected from 9 research institutes and 79 entrepreneurs identified by research institutes as users of R&D results. Two separate sets of questionnaire were administered one for the research institutes and the other for the entrepreneurs. The sets of questionnaire were used to elicit information such as the level of R&D activities, methods of transferring R&D results to investors, and factors militating against the commercialization of research results. Secondary data obtained from available publications included the research reports and published articles of research institutes. The data obtained were analyzed using descriptive and inferential statistics, such as Analysis of Variance (ANOVA) and Duncan Multiple Range Test. A total of 104 research results were generated, out of which 54.81% had been transferred to practicing and prospective investors. Out of the R&D results transferred, 56.14% were commercialized by the institutes themselves while 29.82% were commercialized by the investors. In addition, various methods of transfer used by the research institutes include seminar (3.13), workshop (3.63), trade fairs/exhibitions (3.13), technical assistance service (3.50) and feasibility studies (3.50), on a Likert scale of 1-4. There was significant difference in the effectiveness of the methods of transferring R & D results by the research institutes (F = 16.147, p ≤ 0.05). However, seminar, trade fairs, technical assistance services, feasibility studies and workshops (3.13 - 3.63) had the same degree of effectiveness. The study further showed that the major factors affecting commercialization of R&D results were lack of funds by investors (4.88), unsustainable government policy (4.50), lack of infrastructural facilities (3.88) and apathy to local R&D results adoption (3.63) on a Likert scale of 1-5. There was significance difference in the degree of severity of the factors affecting commercialization of R & D results (F = 6.704, p≤ 0.05). Factors with high rating affecting commercialization of R & D results with the same significant were lack of funds and unsustainable government policy (4.50 - 4.88), while other factors with similar significance were lack of facilities for demonstration, lack of government and institutional support for SMEs and apathy to local R & D results adoption (3.00 - 3.50). The study concluded that the utilization of R&D results by the research institutes and investors were low. Workshop was the most effective method of transferring R&D results, while the greatest limiting factor for R&D results commercialization was lack of fund by investors.
