Agilität als Chance für einen neuen Anlauf zum demokratischen Unternehmen?

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.     

Meeting Cheikh Anta Diop on the Road to African Resurgence

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.     

Estimation of age from epiphyseal union at the wrist and ankle joints in the capital city of India

Various studies conducted in and outside India for estimation of age from long bone joints revealed that unlike other vital parameters no uniform pattern exists for epiphyseal union of long bones in different countries of the world and also in different parts of the same country. A radiological study was conducted in 180 boys and girls of the capital city of India, Delhi, between the age group of 14-20 years to find out the age at which epiphyseal union at wrist and ankle joint takes place. The result of the study showed that the wrist joint epiphyseal union is completed in all cases in the age group of 19-20 years in males and 18-19 years in females. In the ankle joint, 17-18 years was the age group in males and 16-17 years the age group in females which showed complete epiphyseal union in all cases.     

In- and out-flows of elements in bones embedded in reference soils

Possible exchanges of elements between bone and the surrounding soil after being embedded underground for 2 years were estimated. Bone pieces were samples from human vertebrae without any treatments after resection. Sixteen elements were determined by atomic emission mass spectrometry. These were divided into three types; Type I, an in-flow in which elements increased, as in Fe, Al and Ba; type II, a balanced decrease in which changes were found in S, Mg and Zn; and type III, an out-flow in which elements, such as Ca and P, entered into bones from embedded soils. These exchanges depended on the varying nature of soils and also on the time underground. The exchanges were progressed in duration of the time after burial. Data obtained are possible references to judge the time-lapse after burial of bones in relating to characters of soils embedded, and to identify proper bone elements from containment elements.     

Handedness identification from intertubercular sulcus of the humerus by discriminant function analysis

The accurate determination of skeletal handedness is a critical requirement in physical anthropology and forensic science. To differentiate handedness, discriminant function analysis is applied using the parameters of right and left intertubercular sulci. A total of 200 matched unpaired adult humeri (100 right and 100 left), collected from the Department of Anatomy, were used to measure four parameters of the intertubercular sulcus namely, width (X1), depth (X2), angle of medial wall (X3) and angle of lateral wall (X4) and to note the presence of supratubercular ridge of Meyer (X5). The discriminant function obtained with the significant variables, angle of medial wall (X3), angle of lateral wall (X4) and presence of the supratubercular Meyer (X5) is: Y = 0.093X3 + 0.056X4 + 0.775X5 - 13.46. The accuracy of correct classification using the discriminant function is 89% which is the best starting point for handedness determination approach. The methodology of using discriminant function can be crucial for medicolegal jurisprudence.
