In Japan, the disruption of ecosystems caused by alien fish in lakes and ponds is a major issue. To address this problem, we propose that the robotic fish COMET can assist in alien fish extermination by adding the function of spear shooting. The way of extermination is that when COMET finds an alien fish, let COMET approach an alien fish without being wary it and spear it. In this study, we investigated the spear shooting process under different movement conditions to determine the impact on the accuracy of the trajectory of the spear. The results confirmed that a certain set of conditions can improve the accuracy of hitting the target with a spear using specific movements of the robotic fish.

Job (Ayyūb) is a byword for patience in the Islamic tradition, notwithstanding only six Qur'anic verses are devoted to him, four in Ṣād (vv.41-4), and two in al-Anbiyā' (vv.83-4), and he is mentioned on only two other occasions, in al-Ancām (v.84) and al-Nisā' (v.163). In relation to the space devoted to him, he could be accounted a ‘lesser’ prophet, nevertheless his significance in the Qur'an is unambiguous. The impact he makes is achieved in a number of ways. One is through the elaborate intertext transmitted from the Companions and Followers, and recorded in the exegetic tradition. Another is the way in which his role and charisma are highlighted by the prophets in whose company he is presented, and the shifting emphases of each of the sūras in which he appears. Yet another is the wider context created by these sūras in which key words and phrases actualize a complex network of echoes and resonances that elicit internal and transsūra associations focusing attention on him from various perspectives. The effectiveness of this presentation of him derives from the linguistic genius of the Qur'an which by this means triggers a vivid encounter with aspects of the rhythm of divine revelation no less direct than that of visual iconography in the Western Tradition.

Judaism is often understood as the way of life defined by the Torah of Moses, but it was not always so. This book identifies key moments in the rise of the Torah, beginning with the formation of Deuteronomy, advancing through the reform of Ezra, the impact of the suppression of the Torah by Antiochus Epiphanes and the consequent Maccabean revolt, and the rise of Jewish sectarianism. It also discusses variant forms of Judaism, some of which are not Torah-centered and others which construe the Torah through the lenses of Hellenistic culture or through higher, apocalyptic, revelation. It concludes with the critique of the Torah in the writings of Paul.

Subject. In this article we analyze how machinery, science and technologies influence the sociocultural environment that engenders the teacher's paradigm of values and views of life. Objectives. We herein outline guidance to predict the way teachers' views of life might evolve in corresponding sociocultural periods more precisely. The article analyzes making more precise forecasts of oncoming economic crises, which will cause some changes in teachers' mindset. Methods. The study involves learning methodologies, methods of prediction and forecasting, including foresight. Results. We propose and analyze the theory holding that the human civilization passes cycles during its sociocultural development in terms of a new set of values in contemporary teachers' views of life. The article sets forth our recommendations on innovation-driven views of life, mindset and thinking and, consequently, the development of intellectual qualities, knowledge, skills, cognitive activity, positive motivation to the professional activity of a teacher and alumni during more elevated periods, which requires to more precisely predict the way teachers’ mindset may change in certain sociocultural periods. Conclusions and Relevance. As the human civilization enters the innovation-driven sociocultural period, teachers and social relationships should demonstrate more innovative and environmentally-friendly attitudes and views of life.

Technology in education is a global phenomenon affecting learners of all ages. The breadth and variety of available tools make it difficult to implement a standardized method for assessing the impact of technology on learning. The lack of a consensus on good and bad practices results in inconsistent application and mixed learning results.   This article takes a look at the adaptation of technology to education and examines the various tools used to enhance learning. We discuss the advantages and disadvantages of using technology, as well as review methodologies for evaluating the impact.   The essay concludes by identifying several problems with the way technology is evaluated and offers suggestions for further research to address those problems.

The present paper aims at examining the extent to which Moroccan cinema could establish a diasporic visual discourse that cements national identity and contests the impact of westernization on migrants. Moreover, through the analysis the way in which independent identities are constructed in the host land, the article tries to incorporate a feminist discourse to highlight the role of the female subject in retrieving its own agency by challenging patriarchal oppression. Therefore, we argue that Mohammed Ismail’s feature-length film Ici et là (Here and There) has partially succeeded in creating a space for its diasporic subjects to build up their own independent identities beyond the scope of westernization and patriarchy.

The book is a comprehensive examination of John Cage’s seminal Concert for Piano and Orchestra. It places the piece into its many contexts, examining its relationship with Cage’s compositional practice of indeterminacy more generally, the importance of Cage’s teacher, Arnold Schoenberg, on the development of his structural thought, and the impact of Cage’s (mis)understanding of jazz. It discusses, on the basis of Cage’s sketches and manuscripts, the compositional process at play in the piece. It details the circumstances of the piece’s early performances—often described as catastrophes—its recording and promotion, and the part it played in Cage’s (successful) hunt for a publisher. It examines in detail the various ways in which Cage’s pianist of choice, David Tudor, approached the piece, differing according to whether it was to be performed with an orchestra, alongside Cage delivering the lecture, ‘Indeterminacy’, or as a piano solo to accompany Merce Cunningham’s choreography Antic Meet. It demonstrates the ways in which, despite indeterminacy, the instrumental parts of the piece are amenable to analytical interpretation, especially through a method which exposes the way in which those parts form a sort of network of statistical commonality and difference, analysing, too, the pianist’s part, the Solo for Piano, on a similar basis, discussing throughout the practical consequences of Cage’s notations for a performer. It shows the way in which the piece played a central role, first, in the construction of who Cage was and what sort of composer he was within the new musical world but, second, how it came to be an important example for professional philosophers in discussing what the limits of the musical work are.

This chapter contrasts the way that the political settlement in both countries shaped the pattern of redistribution, reform, and corruption within public finance and the implications that this had for economic transformation. Differences in the impact of corruption on economic transformation can be explained by the way that their political settlements generated distinct patterns of competition and collaboration between economic and political actors. In Vietnam corrupt activities led to investments that were frequently not productive; however, the greater financial discipline imposed by lower-level organizations led to a higher degree of investment overall in Vietnam that supported a more rapid economic transformation under liberalization than in Tanzania. Individuals or small factional networks within the VCP at the local level were, therefore, probably less able to engage in forms of corruption that simply led to capital flight as happened in Tanzania, where local level organizations were significantly weaker.

The Conclusion returns to the guiding questions introduced in the Introduction, looking at the way in which the book’s chapters answered them. As such, it identifies recurring themes, experiences, structures, motives, and trends over time. By summarizing the result of the chapters’ research into the interaction between the Secretaries-General and the Security Council, some lessons are identified on the changing calculus of appointments, the conditions and relevance of the international context, the impact of different personalities in that interaction, the changes in agenda and composition of the Council as well as different formats of interaction and different challenges to be met in the realm of peace and security, administration, and reform, as well as concepts and norms. Taken together, they also illustrate the potential and limitations of UN executive action.

This article looks at Engels’s writings to show that his ideas about the role of labour in the evolution of human beings in a dialectical relationship between human beings and nature is a crucial starting point for understanding human society and is correct in its essentials. It is important for understanding that we developed as a species on the basis of social cooperation. The way human beings produce and reproduce themselves, the method of historical materialism, provides the basis for understanding how class and women’s oppression arose and how that can explain LGBTQ oppression. Although Engels’s analysis was once widely accepted by the socialist movement, it has mainly been ignored or opposed by academic researchers and others, including geographers, and more recently by Marxist feminists. However, anthropological research from the 1960s and 1970s as well as more recent anthropological and archaeological research provide overwhelming evidence for the validity of Engels’s argument that there were egalitarian, pre-class societies without women’s oppression. However, much remains to be explained about the transition to class societies. Engels’s analysis of the impact of industrial capitalism on gender roles shows how society shapes our behaviour. Engels’s method needs to be constantly reasserted against those who would argue that we are a competitive, aggressive species who require rules to suppress our true nature, and that social development is driven by ideas, not by changes in the way we produce and reproduce ourselves.
