This article is aimed at examining the causes of insecurity and violence in Nigeria and around the world. It discusses the active roles libraries play in promoting peace and security in different countries. It highlights the fact that several threats to lives, ranging from terrorism, communal and tribal clashes, kidnapping, pollution, health, physical and environmental hazards, and economic crisis among others, can be curbed through information and intelligence services. Premised on these, this article seeks to analyze and make recommendations for the promotion of literacy by libraries, build collaborative relationships between librarians and security operatives, and provide suggestions for the provision of current information against terrorism and security of lives and properties. It also seeks to provide current news on terrorism and intelligence services in Nigeria and around the world, and on social and national security for peaceful co-existence in communities.  相似文献

Objective

The aim of the current study was to evaluate the effect of ultraviolet (UV) photofunctionalization of dental titanium implants with exposure to the oral cavity on osseointegration in an animal model.

Methods

Forty-eight titanium implants (Camlog® Conelog® 4.3 mmx9.0 mm) were placed epicrestally into the edentulous jaws of three minipigs and implant stability was assessed by measuring the implant stability quotient (ISQ). Prior to implantation half of the implants were photofunctionalized with intense UV-light. After three months, the implants were exposed and ISQ was measured again. After six months of implant exposure, the minipigs were sacrificed and the harvested specimens were analyzed using histomorphometric, light, and fluorescence microscopy.

Main results

Forty-two of 48 implants osseointegrated. The overall mean bone-implant contact area (BIC) was (64±22)%. No significant differences were found in BIC or ISQ value (multivariate analysis of variance (MANOVA), P>0.05) between implants with and without exposure to UV photofunctionalization.

Conclusions

No significant effects were observed on osseointegration of dental titanium implants nine months after exposure of UV photofunctionalization.

Pupils’ attitudes influence both learning and teaching processes and affect the way pupils will engage with art as adults. This article introduces an attitude scale, the Attitude Scale for Art Experienced in School (ASAES), which comprises four subscales: enjoyment, confidence, usefulness, and support. A three-step procedure was followed for the construction and validation of the scale which was administered to 420 primary school pupils in Cyprus. The scale's psychometric properties are evaluated through Confirmatory Factor analysis. The findings indicate that teachers’ art specialisation and attitudes towards art teaching, pupils’ perceived competence and pupils’ gender are three important variables that influence the formation of pupils’ attitudes. Important interactions between these variables are also reported.  相似文献

The present study investigated whether young children are gullible and readily deceived by another's lies. Specifically, this study examined whether young children believe a lie teller's statement when the statement violates their developing knowledge of a distinction between reality and fantasy. In the first three experiments 3- to 6-year-olds (N = 293) were presented with either a story or a live staged event in which an individual made an implausible statement about a misdeed (claiming that a ghost jumped out of a book and broke a glass). A significant age effect was obtained: 5- and 6-year-olds tended to report that the individual who made the implausible statement had actually committed the misdeed, whereas 3- and 4-year-olds tended to accept the claim of the protagonist. Experiment 4 revealed that 5- and 6-year-olds (N = 43) not only disbelieved an individual's implausible statement but also inferred that the individual was lying and had a deceptive intent. In contrast, Experiment 5 revealed that 3- and 4-year-olds (N = 41) had difficulty disbelieving an individual's implausible claim about an inanimate object (i.e., the claim that a chair came alive and broke the glass). The findings suggest that 5- and 6-year-olds are not so gullible as previously thought, and that they use their well-developed real-world knowledge to detect scapegoating lies. In contrast, many younger children tend to believe another's implausible lies, perhaps due to the fact that the knowledge needed to detect such lies has not yet been consolidated.  相似文献

Ethical standards for counselor training require remediation of students with professional performance deficiencies. However, standards fail to specify the type or extent of remediation necessary to safeguard students' legal rights or justify dismissal if remediation is unsuccessful. Critical assessment of remedial practices in counselor preparation has occurred primarily in the courts when the constitutionality of specific practices was challenged. Prompted by a recent court challenge and its implications for curricular and policy change (C. R. McAdams, V. A. Foster, & T. J. Ward, 2007), this article examines court‐tested methods of student remediation and presents them as a guide for developing just and fair student remediation policies.  相似文献

The now late great Max Velthuijs was filmed in April 2004 discussing his work with Victoria de Rijke and Howard Hollands, who began the interview expecting Max to be working under certain artistic and cultural influences, none of which seemed to be the case! Max describes what brought him home to Andersen Press, the freedom of children’s picturebooks and his particular way of working, the irony of the white canvas, his attachment to certain symbolic motifs such as apples and blackbirds, and his affinity with the creatures that make up the universally popular and internationally acclaimed Frog series.This piece draws on many voices: those of Max Velthuijs, (represented here in italics), the interview questioners Victoria de Rijke, Howard Hollands & camerawoman Rebecca Sinker (in bold type), and comments (in ordinary type) drawing upon Joke Linders’ biography Ik Bof dat ik een Kikker Ben (Glad to be a Frog) Leopold, 2003, kindly translated into English by Lena Winter.  相似文献

In post‐industrial societies saturated with the multimodal texts of consumer culture—film, computer games, interactive toys, SMS, email, the internet, television, DVDs—young people are developing literacy skills and knowledge in and for a world significantly changed from that of their parents and educators. Given this context, this paper seeks to demonstrate the necessity of rethinking and extending traditional notions of text and literacy, and consider the social and cultural implications of such a shift.  相似文献
