A trip down memory lane and a lesson on scientific integrity.

The book contains essays on current issues in Social and Political Sciences, such as the issues of governance and social order; social development and community development; global challenges and inequality; civil society and social movement; IT-based community and social transformation; poverty alleviation and corporate social responsibility; and gender issues. Asia and the Pacific are the particular regions that the conference focuses on as they have become new centers of social and political development. Therefore, this book covers areas that have been traditionally known as the social and political areas such as communication studies, political studies, governance studies, criminology, sociology, social welfare, anthropology and international relations. The book will help shed light on what social and political scholars in Asia and the Pacific have done in terms of research and knowledge development, as well as the new frontiers of research that have been explored and opening up, which can connect the two regions with the rest of the globe.

Public choice approaches have revolutionized contemporary political science, particularly in the United States, where a "new right" political movement has developed. This book develops a critique of new right views through its coverage of aspects of the public choice/new right literature.

The study was conducted to assess the capacity building needs of Agricultural Science teachers for innovative instructional delivery in secondary schools in Rivers State, Nigeria. Descriptive survey research design with a sample of 28 Agricultural Science teachers drawn through purposive sampling from a population of 244 teachers in secondary schools drawn from both Andoni and Opobo/Nkoro Local Government Areas of Rivers State was used. Three research questions guided the study. A 20-item research instrument entitled "Capacity Building Needs of Agricultural Science Teachers Questionnaire (CBNASTQ)" was developed and used for the study. Likert 5-point mean rating scale was adopted. Cronbach's Alpha reliability method was used to determine the internal consistency of the CBNASTQ and a reliability coefficient of 0.81 was obtained. Mean and standard deviation were used to answer the research questions. The study revealed amongst others that Agricultural Science teachers need to improve on the skills acquired through continuous professional development. Based on the findings, it was recommended amongst others that Government should ensure the continuous capacity building of teachers through the organization of workshops, seminars, symposia, and conferences to enable them to interact with one another and acquire new skills.

Use of computer simulated games among children/students is common and science students are not left out. Whereas poor performance and dwindling enrolment in science subjects have been observed among students in Nigeria, not much evidence has emerged at solving the problems from computer simulation mode of teaching. This study was designed to determine the effects of computer simulation package (CSP) on academic performance of senior secondary school students on the concepts of pollution and energy. Using multi-stage purposive and simple random sampling technique, six hundred (600) Senior Secondary (SS) class two students were selected from twelve co-educational schools consisting of four (4) schools in each of the senatorial districts of the State and fifty (50) students participated. Three hundred (300) students each were used for experimental and control groups. A validated Students' Achievement Test (SAT) instrument, having 30 multiple choice items was used to generate pre-test and post-test data. Analysis of Covariance (ANCOVA) was used to test each of the hypotheses at 0.05 level of significance. Findings showed that the use of computer simulation package (CSP) has significant effect on students' academic performance (F-cal 955.93, P = 0.00*< 0.05) while gender showed no significant influence on students' performance (F-cal 1.03, P = 0.312 >0.05). Thus, science teachers should be trained and retrained in seminars, workshop and conferences on the use of computer simulation packages in order to encourage personalized learning among science students.

AbstractAchieving more sustainable land and water use depends on high‐quality information and its improved use. In other words, better linkages are needed between science and management. Since many stakeholders with different relationships to the natural resources are inevitably involved, we suggest that collaborative learning environments and improved information management are prerequisites for integrating science and management. Case studies that deal with resource management issues are presented that illustrate the creation of collaborative learning environments through systems analyses with communities, and an integration of scientific and experiential knowledge of components of the system. This new knowledge needs to be captured and made accessible through innovative information management systems designed collaboratively with users, in forms which fit the users' 'mental models' of how their systems work. A model for linking science and resource management more effectively is suggested. This model entails systems thinking in a collaborative learning environment, and processes to help convergence of views and value systems, and make scientists and different kinds of managers aware of their interdependence. Adaptive management provides a mechanism for applying and refining scientists' and managers' knowledge. Copyright © 2003 John Wiley & Sons, Ltd.
