Pre-Service Teachers' Internet Usage a Function of Demographic Factors: the Case of a Nigerian College of Education

With the overreaching acceptance of ICT in education and access to Internet occasioned by advancement in technology, this paper investigates pre-service teachers' use of Internet in a college of education. The study was a descriptive survey. Data was collected using a researcher designed instrument tagged “Student Internet Use Scale” (SIUS). The population comprised of all NCE pre-service teachers in Alvan Ikoku Federal College of Education Owerri Nigeria. Findings show that mobile phones remains the most widely used mode of internet access with social networking, searching for information on school assignments, chatting forming the major reasons why they surf the net. Social networking is the major purpose for Internet use by female pre-service teachers while school related activities are of priority to males. The difference in purpose of internet use according to gender is however not statistically significant; similarly, there is no statically significant difference between male and female pre-service teachers in the frequency of Internet USAge. The result has far reaching implication for provision and use of Internet facilities to enhance teaching and learning in the College and colleges of education in Nigeria

Women Abuse Screening Tool: A Validation Study on Nigerian Pregnant Women

Domestic violence is identified across the globe as a menace as it poses a threat to the mental health of its victims, the significant others of the victim and the security of a nation at large. In some cases, the victim of domestic violence is a pregnant woman and harm is caused not only to a woman but her fetus also and this calls for urgent psychological assessment and intervention. Although there is no doubt that psychological tests are effective in the assessment of domestic violence, using the psychometric properties obtained from a different population may produce generate inaccurate findings. This paper therefore attempts the validation study of Women Abuse Screening Tool (WAST) using a sample of 379 pregnant women attending antenatal clinic at the State Specialist Hospital, Osogbo, Osun State, Nigeria. The study derived a Cronbach’s Alpha Reliability of 0.758, p \u3c.05 and a Guttman split-half coefficient of 0.683, p \u3c.05. Furthermore, concurrent validity of Women Abuse Screening Tool (WAST) and Ongoing Abuse Screen (OAS) was established as 0.29, p\u3c.05. The norms of the instrument were given as 2.38 for tolerable level of domestic violence and 5.79 for severe and pathological level of domestic violence. Authors conclude that Women Abuse Screening Tool has acceptable psychometric properties to justify its usage for the assessment of level of domestic violence among pregnant women in Nigeria and other nations with similar socio-cultural backgrounds

Testing the Design of a Library Information Gateway

In autumn of 1999, librarians at Appalachian State University and Georgia Southern University had decided to revise their Web sites. Each institution’s site had been in place for more than a year, and experience with library users had shown that there were certain aspects of the sites’ designs that were confusing. Previous efforts to improve these library sites had involved the pooling of criticisms from the librarians and users, and then a small group of library faculty and staff would attempt to create new designs that avoided the weaknesses of the old designs

An ArcGIS Tool for Modeling the Climate Envelope with Feed-Forward ANN

This paper is about the development and the application of an ESRI ArcGIS tool which implements multi-layer, feed-forward artificial neural network (ANN) to study the climate envelope of species. The supervised learning is achieved by backpropagation algorithm. Based on the distribution and the grids of the climate (and edaphic data) of the reference and future periods the tool predicts the future potential distribution of the studied species. The trained network can be saved and loaded. A modeling result based on the distribution of European larch (Larix decidua Mill.) is presented as a case study

Testing the Design of a Library Information Gateway

In autumn of 1999, the library World Wide Websites at Appalachian State University and Georgia Southern University had been in place for more than a year, and many library users reported that certain aspects of the sites’ designs were confusing. In order to alleviate the confusion, librarians from the two universities decided to redesign the sites by determining the greatest sources of confusion. To do this, we studied how patrons used the web sites by way of user-centered usability testing

Improving breeding performance of fingerlings of Clarias gariepinus through intraspecific hybridization

The scarcity of genetically improved fish seed is a major constraint to rapid development of aquaculture in Nigeria due to inbreeding. The study was conducted to monitor breeding indices from intra-specific mating combinations of wild stocks of Clarias gariepinus. Broodstock of C. gariepinus were collected from Lokoja (LK), Makurdi (MK), Agenebode (AG) and Onitsha (ON) and compared with domesticated strain. 16 mating combinations of parental and intraspecific mating combinations were conducted in triplicates. Results were subjected to one way analysis of variance (ANOVA) (α= 0.05). The results showed collection from Onitsha had highest values of fertilization (95.2%), hatchability (87.6 %) and survival (66.0 %), followed by crosses from female from Onitsha : ♀ON X ♂LK, ♀ON X  ♂MK and ♀ON X  ♂AG having 95.8 %, 91.1 % and 88.8 % (fertilization), 68.7 %, 61.9 % and 60.7 % (hatchability) and 61 %, 57 % and 63 % (survival) respectively. Domesticated strain had least values (81.9 %, 59.4 % and 51 %) fertilization, hatchability and survival respectively. ANOVA (α< 0.05) showed variation in fertilization, hatchability and survival. The better performing strains could be explored for genetic development. However, protein and gene profiling of these natural populations may be necessary to identify the proteins and genes responsible for these variations in breeding performances.Key Words: Breeding, performance, Clarias gariepinus, hybridizatio

Meseron Therapy and Christian Counselling: A Synergy

Christian Counselling (CC) is the practice of talking with individuals, couples, and families to increase their understanding of emotional and religious conflicts and to help resolve problems using Christian religious injunctions and other related resources.  Meseron Therapy (MT) was developed in accordance with the Nigerian belief in the power, potency and meaning of spoken words and its consequences. MT entails rejecting negativities and accepting the positives, with the techniques of MT reflecting a cognitive orientation. MT and CC approaches have several common grounds. The basic assumptions of MT such as the power of the spoken words to sensitize action, the ignition of man’s inherent potential for change, replacement of a negative status quo with constructive actions and the view of man as a striving creature all have Biblical support. Also, MT’s views on human nature and the causes of psychological disturbance agree with Christian teachings and beliefs. Application of Meseron therapeutic techniques and procedures to CC can be done by using Biblical teachings to enable clients sustain good health, encouraging the good use of endowments, assisting client in mental restructuring through motivation to strive, building and encouraging possibility thinking, enabling the clients to reject distractions from goal accomplishments and getting clients to say it right and synergize their thoughts, words and actions.

Contribution of cultural heritage values to steppe conservation on ancient burial mounds of Eurasia

The cultural legacies of ancient and lostcivilizations are rarely considered in the conservation of the Eurasian steppe biome. Weused a data set containing more than 1000 records on localities, land cover, protectionstatus, and cultural values related to ancient steppic burial mounds (kurgans); we evaluatedhow these iconic and widespread landmarks can contribute to grassland conservation in the Eurasian steppes, which is one of the most endangered biomes on Eart
