Police witness intelligence stated a murdered adult male “Fred” had been vertically buried in wooded hilly terrain 30 years ago in the Midlands, U.K. Conventional search methods were unsuccessful; therefore, the police requested a geophysical investigation to be undertaken to determine whether “Fred” could be detected. A multiphased geophysical approach was conducted, using bulk ground conductivity and metal detectors, then follow‐up magnetics and ground penetrating radar (GPR) survey profiles on electromagnetic (EM) anomalous areas. A tight grid pattern was used to account for the reduced target size. Relatively high‐resolution EM and GPR techniques were determined optimal for this terrain and sandy soil. Geophysical anomalies were identified and the most promising intrusively investigated, and this was found to be a large boulder and tree roots. Study implications suggest careful multiphase geophysical surveys are best practice and give confidence in cold case searches. This study yielded a no‐body result, effectively saving police time and costs from further investigations. 相似文献

ABSTRACT Recently, states have enacted teacher-carry laws. While controversial, little scholarship has tapped public attitudes toward such reforms. Because public opinion shapes policy, the public is an important stakeholder in this debate. Thus, we investigated three questions. First, how supportive is the public of arming teachers? Second, what demographic and social divides exist, if any, for reform approval? Finally, do crime-related perceptions, concerning views about public safety, and criminogenic influences shape policy preferences? We test these questions using a 2018 poll of Virginia residents (N = 521). Overall, approval for teacher-carry is split. Crime-related perceptions mediate some of the initial social and demographic divides in opinion but other correlates, such as parental status, remain salient predictors of views. Implications are discussed. 相似文献

There has been a long-standing discussion since the 1980s about the question whether new production models harbor a potential for extended employee participation and involvement, in most cases with disillusioning results. This paper is concerned with so called “agile methods”, which play an important part in the area of knowledge work in the course of the digital transformation. On the basis of two case studies from software development and industrial R&D, the paper examines the concrete implementation of these methods and the employees’ perspective upon them and their consequences. The result is that agile methods present a potential for extended employee participation and involvement; however, the realization of this potential depends on the concrete way how the agile concept of “empowerment” is implemented. 相似文献

The African people's relentless struggle to tell their own stories and take charge of their own historical languages is a prerequisite for achieving an African Renaissance. This argument, informed by Afrocentricity—a theoretical framework which advances the view that any examination of African issues must be informed by African history and culture—takes its cue from the great Senegalese Pan-Africanist and African Renaissance advocate, Cheikh Anta Diop. The year 2018 marks 70 years since Diop, at a tender age of 25, wrote his essay When will we be able to speak of an African Renaissance? On the occasion of the 70th anniversary of this article, it is appropriate that the African Renaissance project advocates take a moment and deeply reflect on how they can take African scholarship to higher levels and intensify and consolidate the struggle to liberate Africa from being preoccupied with the Eurocentric trajectory of privileging Europe and Europeans in all aspects of life—the intellectual, political, cultural, social and material. This article argues that embracing Africology—the Afrocentric approach to scholarship—is the first step towards the liberation of a scholarship project. Diop dedicated his life to using sciences—both the natural and social sciences for the liberation of Africa and humankind—to liberate Africans from inferiority complex, and Europeans from superiority complex. Although Diop recognised both the importance of science and ideology in the service of humanity, he drew a line between them. 相似文献
