Policies And Programs

Agriculture is in critical state in Nigeria with domestic food production being less than the growing population. The chapter analyzes the ongoing transformation of subsistence agriculture to commercial in Nigeria and the attendant effects of large-scale land acquisition on small-scale farmers. It uses both theoretical and empirical research designs with direct interviews of relevant stakeholders and case studies. It reviews past and present policies and programs aimed at transforming agriculture from subsistence to commercial in Nigeria. The results reveal that large-scale land acquisition and farming is not new in Nigeria. Acquisitions of land by foreigners has always been with the help and consent of government, unlike the case when it involves indigenous investors. Acquisitions have in most cases been characterized by conflicts between the landowners or tillers and investors. To transition successfully from subsistence to commercial agriculture, there is a need for strong collective actions between the depraved land owners, government, and investors.

We have been long involved in large-scale computational fluid dynamics (CFD) simulations in aerospace research. These days, as the computer power grows, output data from the simulations becomes larger and larger, and we feel that the current visualization methodology has its limitation in understanding. Thus, with the target concepts of reality, collaboration, and communication, we has built an immersive and interactive visualization system with a large-sized wall-type display. The system, which has been in operation since April 2001, is driven by a SGI Onyx 3400 server with 32 CPUs, 64Gbytes memory, and 6 IR3 graphics pipelines, and comprises a 4.6×1.5-meter (15×5-foot) rear projection screen with 3 high-resolution CRT projectors, supporting stereoscopic viewing, easy color/luminosity matching, and accurate edge-blending. The system is mainly used for visualization of large-scale CFD simulations. This paper will describe the new visualization system introduced at the National Aerospace Laboratory of Japan, and the features of the system are discussed while illustrating some typical visualized examples.

Decades of work have illuminated the influence interpersonal networks exert on voting behavior, political participation, the acquisition of political knowledge, tolerance, ambivalence, and attitude polarization. These central findings have largely been grounded in examinations of political discussion and have remained robust to measurement differences of key concepts like disagreement, various data collection methods, and multiple research designs ranging from the cross-sectional to large-scale field experiments. By comparison, scholars understand considerably less about individuals’ motivation to approach their social contacts when it comes to politics, and about why networks produce the outcomes that they do; this calls researchers to reflect on and revisit previous research, but also to consider new paths of research. Although there is a growing body of promising work focused on “whole,” or complete, networks, much can also be gained by better integrating social psychology into the study of egocentric, or “core,” political networks. Answering these (and other) questions will help connect current findings, emerging methods, and nascent theory. Such connections should advance dialogues between research on group influence, discussion networks, and individual political behavior.

The Individual

Although the last 20years have seen a focus upon evidence-based therapies, there are arguments that much of the so-called “evidence” produced is, in fact, irrelevant to the mental health practitioner in the field, principally because of the use of large-scale group designs in clinical controlled studies of the effectiveness of one therapy over another. By contrast, and with particular relevance to the practitioner who is both scientist and therapist, single subject research designs and methodologies for data analysis can be applied in ways that allow for generalisation to everyday practice. To inform the readership, the rationale underlying n = 1 studies is described, with some explanation of the major designs and their application to typical cases in guidance and counselling. Issues of inferential deductions from data, variations of design, data analysis via visual and statistical procedures, and replication are discussed. Finally, a case is argued for the introduction of n = 1 reports within the Australian Journal of Guidance and Counselling to better inform the readership about clinical research findings relevant to their practices.

In this paper, the authors present the OpenWebGlobe project (http://www.openwebglobe.org). The authors also discuss the OpenWebGlobe SDK. OpenWebGlobe SDK is an open source framework for creating massive 3D virtual globe environments and interactively exploiting them in web browsers using HTML5 and WebGL, allowing for the creation of large scale virtual 3D globes with detailed contents and their interactive visualization directly within a broad spectrum of Web browsers.
