Determinants of e-government diffusion in Nigeria

While Nigeria began its e-government initiatives in the early 2000s, the country is still in the early stages of e-government development, with very low e-government diffusion among its population. Through the administration of survey questionnaires, this paper first identifies the benefits of e-government, and then examines factors of e-government diffusion in Nigeria via three theoretical models of innovation diffusion (Technology Acceptance Model, Diffusion of Innovation theory, and the Unified Theory of Acceptance and Use of Technology). Results of the study suggest that the anticipated benefits of e-government in Nigeria are similar to those found in other studies in the e-government literature. Prominent factors of e-government diffusion found in the study capture the dimensions of the three theories. However, due to the unique nature of the Nigerian context, two factors (trust in government and reliable electricity supply) of e-government diffusion identified in the study are not within the dimensions of the theoretical models. The paper suggests that the Nigerian government should address the factors identified in the study (such as reliable electricity supply, perceived usefulness, perceived ease of use, relative advantage, etc.) in order to facilitate e-government diffusion in the country. The study therefore provides a basis within which policy makers should aim to improve the deployment and diffusion of e-government in Nigeria.
The Effects of Separation and Divorce on Parent–Child Relationships in Ten European Countries

Numerous studies have demonstrated a negative long-term effect of divorce on father–child relationships. Compared to married fathers, divorced fathers see their adult children less frequently, receive less instrumental support from them in old age, and their children evaluate the relationship more often as poor (Lye 1996). There are several reasons for this. First, after divorce, mothers usually gain custody which reduces the father’s role in the upbringing of the children (Seltzer 1991). As a result, the father has fewer opportunities to invest in his children and this may have negative effects on what he receives from the children when they are older (Spitze and Logan 1989). Second, divorced fathers may see their adult children less frequently because of sex-role specialisation during marriage. Hence, when gender roles are divided along traditional lines, married men benefit from a wife who takes care of family matters, for instance, by arranging visits from children and buying presents for the children’s birthday (Hagestad 1986; Rosenthal 1985). When men divorce, they not only lose a spouse, they also lose a kinkeeper, which may explain part of the decline in intergenerational contact (Kalmijn 2007). A third possible reason for reduced contact is that divorced fathers may exhibit more behavioural problems. Research has shown that behavioural problems on the part of fathers are often a reason for divorce. Examples are mental health problems, substance abuse and aggressive behaviour (Kitson 1992; De Graaf and Kalmijn 2005). While many divorced fathers will not display such problems, some do, and if they do, this may have negative effects on the relationship they have with the children. Although there are many arguments pointing in the direction of a negative effect for fathers, there are also reasons to believe that there will be a
Make-Believing Animated Films Featuring Digital Humans: A Qualitative Inquiry Using Online Sources

A qualitative inquiry of reviews of films featuring digital humanlike characters was performed by sampling user comments from three online reviewer aggregator sites: the Internet Movie Database, Rotten Tomatoes and Metacritic. The films chosen for analysis were: Final Fantasy: The Spirits Within (dir. Hironobu Sakaguchi and Motonori Sakakibara, 2001), The Polar Express (dir. Robert Zemeckis, 2004), and Beowulf (dir. Robert Zemeckis, 2007), all produced using CGI animation, together with A Scanner Darkly (dir. Richard Linklater, 2006) whose visuals are depicted by rotoscoping using Bob Sabiston’s Rotoshop software. The authors’ analysis identified individual differences in the viewing experience, particularly in relation to the uncertain ontology of the humanlike characters created using CGI (CGI-Humans). They found examples of reviews indicating an inability to distinguish between real and CGI-Human actors, observations of characters transiently exhibiting realism before returning to their artifice, and of characters being viewed as eerie (analogous to the uncanny valley), thus illustrating a complex and dynamic response to this phenomenon. In some situations, character uncanniness was related to the presence of an atypical feature such as movement of the eyes. Whilst specifically for Beowulf, perceptions became more problematic when there was familiarity with the actor playing the CGI-Human character, with some reviewers describing difficulties in categorizing the character as either real or animated. CGI-Human performances were also characterized by a lack of, or inappropriate, social interaction. Online reviewers did not perceive characters depicted using Rotoshop (Rotoshop-Humans) as eerie; rotoscoping was found to preserve, and possibly enhance, the natural social interactions between actors recorded from the live-action film which was used as the source material for the animation. The authors’ inquiry also identified user motivations for viewing these films and the importance placed by reviewers on the form of display when viewing the CGI films. They situate their interpretation of these findings in relation to Walton’s make-believe theory (Mimesis as Make-Believe: On the Foundations of the Representational Arts, 1990).

A novel visualisation paradigm for three-dimensional map-based mobile services

After several years where 3D maps were only possible to visualise with the powerful desktop computers, the Location-Based Mobile Services (LBMS) technology has finally reached a maturity level that enables the development of 3D map-based Graphical User Interfaces. Nowadays, there is already a vast range of commercial LBMS products available to the masses, mainly in the form of Personal Navigation Assistants (PNAs) and mobile phones featuring GPS functionality and mobile 3D maps. Motivated by commercial interests, many of these products promise to offer the “best visualisation experience ever”, in search for a differentiating factor from the competition. Given the complete disparity of ideas and a visible disorientation in the Mobile Industry, it becomes of uttermost importance to study the visualisation aspects that are concerned with user performance and experience in the exploration of urban environments using 3D maps. In this work, a generic conceptual framework is proposed, whose main purpose is to unify and to objectively evaluate all the relevant visualisation elements (feature vectors) that influence user performance and experience. With this conceptual framework in mind, an online questionnaire was developed and administered to 149 test subjects, in order to measure the real impact of the most important visualisation features. The results clearly demonstrated that, just by displaying buildings with a 3D appearance, subjects were able to match more accurately the real environment with the one presented on a mobile map. Moreover, users were able to perform the tasks entrusted to them faster, if they were provided imagery with a superior level of realism (e.g., Photo-realism). This work proposes a visualisation paradigm of 3D maps for urban environments, by specifying the high-level requirements for generic LBMS, which maximise user performance and experience. The possible conflicts that may arise between these requirements are discussed, and several solutions and alternatives are suggested. To evaluate the applicability of the proposed visualisation paradigm, an automotive navigation system prototype was developed, using the current mobile technology.
Research and Implementation of PCA Face Recognition Algorithm Based on Matlab

This paper researches the theory of PCA (Principle Component Analysis) algorithm and the fea- ture extraction elements in the process of face recognition, summarizes application procedures of PCA algorithm in the process face recognition, and realizes the application of PCA algorithm in the process face recognition in the matlab software. The research content and realization results show that: PCA algorithm is a kind of algorithm which is very suitable for programming and realization of matlab software; the key factor to realize PCA algo- rithm is the selection of the number of feature vectors, which affects the recognition rate and training time of the space sample subset. The higher recognition rate indicates better results in the algorithm implementation; the shorter training time of the space sample subset indicates more excellent algorithm implementation. In the pro- cess of selection of the number of feature vectors, on one hand, there is a need to protect the recognition rate; on the other hand, there is a need to control training time of the space sample subset, in which the recognition rate is a rigid target. The shortest training time of the subset of samples is selected on the premise of meeting the recog- nition rate.
Scoring Rubric Development: Validity and Reliability.

In Moskal (2000), a framework for developing scoring rubrics was presented and the issues of validity and reliability were given cursory attention. Although many teachers have been exposed to the statistical definitions of the terms "validity" and "reliability" in teacher preparation courses, these courses often do not discuss how these concepts are related to classroom practices (Stiggins, 1999). One purpose of this article is to provide clear definitions of the terms "validity" and "reliability" and illustrate these definitions through examples. A second purpose is to clarify how these issues may be addressed in the development of scoring rubrics. Scoring rubrics are descriptive scoring schemes that are developed by teachers or other evaluators to guide the analysis of the products and/or processes of students' efforts (Brookhart, 1999; Moskal, 2000). The ideas presented here are applicable for anyone using scoring rubrics in the classroom, regardless of the discipline or grade level.

Automatic annotation of digital photos

Content-based image retrieval searches for an image by using a set of visual features that characterize the image content. This technique has been used in many areas, such as geographical information processing, space science, biomedical image processing, target recognition in military applications and bioinformatics. Many approaches have been proposed to reduce the gap between the low-level visual features and high-level contents. In this thesis, a multi-class automatic annotation system is developed to bridge the semantic gap. Given an image, the proposed system will automatically generate keywords corresponding to the image contents. The system is evaluated using a large image database consisting of over 16000 images collected from various online repositories. The proposed multi-class annotation system is based on salient features and support vector machines (SVMs). A new feature called gradient direction histogram is proposed for image classiﬁcation. Instead of relying on a single feature, the SVMs in our system can automatically select the most suitable features from a pool of six MPEG-7 visual descriptors and the proposed gradient direction histogram. Multi-class SVMs are constructed using two-class SVMs in di ﬀ erent combinations. We have examined several multi-class support vector machines including one-versus-all SVMs, pair-wise SVMs and decision directed acyclic graph SVMs. The results conﬁrm that the pair-wise and decision directed acyclic graph SVMs are suitable for multi-class applications. In pair-wise SVMs, we propose a voting scheme named conﬁdence score voting. Our results show that, compared to majority voting, conﬁdence score voting improves the classiﬁcation accuracy. Combining salient features leads to a signiﬁcant improvement in the classiﬁcation rate. The proposed system is compared to k -nearest neighbours and neural networks using the same dataset. The results show that the proposed system outper-forms these two classiﬁers in the four-class classiﬁcation problem. The research project also investigates the system performance when the input image is cropped, resized or rotated.
Information Flow in R & D Laboratories

When the carton is erected, the handle can be pivoted from a substantially flat stored position on the top wall to an upright use position for carrying the carton. The handle is formed from three overlapping panels after the blank is folded to provide a handle having superior strength.
A design methodology for fuzzy controllers and comparison with an optimal PD controller for a nonlinear control system

This paper presents a method for designing fuzzy logic controllers by using the experience of human operators and/or control engineers. This five-step method, involving a fuzzy logic controller, uses a modified fuzzy associative memory (FAM) approach. The Magnetic Ball Suspension Problem (a nonlinear system problem) is used for illustrative purposes. Comparisons with an optimal PD controller in the linearized and nonlinear cases are made with the result that not only is the fuzzy logic controller more robust than the optimal PD controller in the sense of stability, but it also provides better performance for a given performance index. <<ETX>>

An experimental evaluation of the effectiveness of random testing of fault-tolerant software

Results of a fault-tolerant software (FTS) experiment are used to show deficiencies of the simple random testing approach. Testing was performed using randomly generated test cases supplemented with extremal and special value (ESV) cases. Error detection efficiency of the random testing approach, with emphasis on correlated errors, was compared to the error detecting capabilities of the ESV data and found deficient. The use of carefully designed test cases as a supplement to random testing, as well as the use of structure based testing are recommended.
Mental Models in Groups

Groups commonly engage in reasoning but the topic is scarcely studied in comparison to individual reasoning. This thesis aims to further the understanding of group reasoning by studying mental models within a distributed cognition framework. This extends current mental model theory by accounting for cognitive systems larger than the individual, including groups. To do this a theoretical proposal is outlined in which the mental model itself is adopted as the unit of analysis. Mental models which are divided between group members such that each holds a part of the whole are referred to as `distributed mental models'. They are contrasted with groups in which each of the group members has all of the mental model, referred to as shared mental models, in which they use an independent rather than a distributed reasoning process. A task was developed to study the effect of the distribution of information within a group on reasoning. This involved conditional inference, but the inferences used had several conjunctions and were couched in a problem solving task to increase the amount of information required for the task and so facilitate the effective distribution of information. Differences in the division of mental models between people are possible in groups that do not exist in individuals. Two factors were studied, the extent to which the parts of the model held by a group member were shared within the group and the extent to which the parts formed autonomous modules that could be used independently by group members. It was found that both of these affected the collaboration of groups but mostly led to similar performance levels. In further experiments sources of difficulty were manipulated which targeted parts of the collaboration which the different divisions of the model had affected. As a result these had differential effects on the collaboration and performance of groups with shared and distributed mental models and also between groups and individuals. Overall, these findings suggest that group reasoning is an area of research with features distinct from individual reasoning and the distributed cognition approach to mental models used here proved fruitful in studying it.
