With the success of CSP technology in the last years more players are active in the market, inducing the need for harmonization of technical terms and methodologies. The mission of the SolarPACES “guiSmo” project which was started in 2010 is to develop a guideline for CSP yield analysis [1]. Activities carried out so far have shown that people have different understandings of many terms used in daily CSP practice. Especially for the development of guidelines, the essential terms need to be clearly defined in order to avoid inconsistencies within the same project. A first version of a nomenclature has been compiled by the “guiSmo” team and will undergo final discussion. The aim is to come to a harmonized version by Summer 2013 which will then be presented at the ASME Energy Sustainability conference. The compilation so far includes essential definitions of terms like direct normal irradiance, incident angles, heat flows, and efficiencies on a system level. The definitions presented will be discussed together with existing standards like the ISO 80000 (physical quantities and units of measurement), the ISO 9488 (Solar energy-vocabulary) and other relevant sources. Although the list of terms is primarily put together for the work in the “guiSmo” project, it might serve as a basis for standardization in the official councils. An international group of solar experts is involved in the preparation of the document in order to ensure high quality and international support for the results.

This chapter distinguishes between fallibilism and infallibilism by appeal to entailment: infallibilists hold that knowledge that p requires evidence which entails that p; fallibilists deny that. It outlines some of the recent motivations for infallibilism, including the infelicity of concessive knowledge attributions, the threshold problem, closure, and the knowledge norm of practical reasoning. Further, we see how contemporary infallibilists attempt to avoid scepticism by appeal either to a generous conception of evidence or a shifty view of knowledge, such as contextualism. The chapter explains the book’s focus on non-shifty versions of infallibilism which defend a generous conception of evidence. It ends by defending the entailment definition of infallibilism over other potential definitions, and outlining the chapters to come.

This chapter summarizes the main parameters of coalitional presidentialism and the key concepts, definitions, explanatory frameworks, indicators, and propositions. It summarizes our understanding of coalitional presidentialism; the distinction between coalition formation and maintenance; the definition of coalitions; the multidimensional understanding of coalition management (the ‘presidential toolbox’); and an analytical framework that emphasizes the motivation of presidents to achieve cost minimization under constraints determined by system-level, coalition-level, and conjunctural factors. It also summarizes our main empirical findings: (1) the characteristics of presidential tools, (2) the substantive patterns of their deployment, (3) the factors that shape the costs of using these tools, (4) the actual (observed) costs of using them, and (5) the potential for imperfect substitutability of these tools. Finally, it concludes with some reflections on the current state of the research on comparative presidentialism.

The kingdom of God in the Old Testament: A brief survey. The kingdom of God is a central concept in the teaching of Jesus, but the question posed by this article is the following: What does the Old Testament say about the kingdom of God? Several Old Testament terms convey the concept of kingdom, kingship and rule of God. This article focuses on the Hebrew and Aramaic ‘technical’ terms for kingdom: mamlākâ, malkût, mělûkâ and malkû. One finds only a few Old Testament references where these terms are directly connected to God, most of them in the post-exilic literature: 1 Chronicles 17:14; 28:5; 29:11; 2 Chronicles 13:8; Psalm 22:29; 103:19; 145:11–13; Daniel 2:44; 3:33 (4:3); 4:31 (4:34); 6:27; 7:14, 18, 27; Obadiah 21. A brief study of these specific references leads to a few preliminary conclusions: The kingdom of God refers to a realm and the reign of God, the God of the kingdom is depicted in different ways, God’s kingdom is eternal and incomparable with earthly kingdoms, the scope of the kingdom is particularistic and universalistic, the Old Testament testifies about a kingdom that is and one that is yet to come, et cetera. It seems that there is no real difference when comparing the ‘kingdom of God’ with the ‘God is King’ passages. One cannot unequivocally declare that ‘kingdom of God’ is the central concept in the Old Testament. However, we must acknowledge that Jesus’s teaching about the kingdom of God did not evolve in a vacuum. His followers probably knew about the Old Testament perspective on the kingdom of God.Contribution: The concept ‘kingdom of God’ is relevant for the church in South Africa, especially congregations who strive to be missional. Unfortunately, the Old Testament perspective was neglected in the past. The purpose of this brief survey is to stimulate academics and church leaders in their further reflection on the kingdom of God.

The Pan-African Film and Television Festival of Ouagadougou (FESPACO) was founded in 1969. It began as an intimate week-long gathering of filmmakers and enthusiasts in the capital of what is now Burkina Faso to watch contemporary films made by African filmmakers. At its peak in the 1990s, it attracted hundreds of thousands of spectators, both local and international. Since the 2000s, iterations have been smaller affairs, significantly impacted by both changes of government in Burkina Faso and wider political instability in West Africa, as well as ongoing debates about what films it should be showcasing. Despite such challenges (and with only one exception in the mid-1970s), however, FESPACO has remained a constant on the African continent, faithfully screening films by African and diaspora filmmakers every two years for more than half a century. FESPACO was conceived in the age of decolonization by a group of men and women who are considered to be the pioneers of African cinema, including the Senegalese writer and filmmaker Ousmane Sembène. It was established as the first sub-Saharan showcase of African filmmaking, an emergent and significant field in the era of independence when cinema was prized for its ability to make visible African realities and to (re)constitute national histories eclipsed by colonial rule. The concept of a distinctly “African” cinema was articulated most extensively by filmmaker and scholar Paulin Soumanou Vieyra and referred to films made by Africans, telling African stories, principally for African audiences. For Vieyra, Sembène, and their contemporaries, it was essential to take back control of the art of cinema on the African continent, where it had predominantly been deployed as a colonial tool; FESPACO was conceived as the regular forum for those committed to its development to come together and share their work. Through the course of its development, FESPACO has been confronted with a number of challenges regarding its form and its evolution. Its strong connections with the Burkinabe state have been seen as both a significant factor for its growth and its success, and, particularly in the era of Blaise Compaoré, as a source for concern regarding freedom of expression. Since the turn of the 21st century, questions about where video filmmaking—an industry that has proliferated on the African continent in a manner unprecedented internationally—fits within FESPACO’s definition of cinema have been consistent. The festival has, over the years, been accused of being both outdated and elitist in its commitment to celluloid, but also of straying from its original remit to showcase African stories for African audiences, accusations it has responded to by the creation of new prize categories and requirements for submission. The year 2019 was one of reflection, but many critics felt that after some difficult years the festival was showing signs of rejuvenation. Though it is now one of many film festivals on the continent committed to showcasing African cinema, there remains significant appreciation for the historic status of FESPACO as a preeminent sub-Saharan cultural institution.

For millennia, mankind has dreamed of creating an artificial creature capable of thinking and acting “like human beings”. These dreams are gradually starting to come true. The trends in the development of modern so-ciety, taking into account the increasing level of its informatization, require the use of new technologies for information processing and assistance in de-cision-making. Expanding the boundaries of the use of artificial intelligence requires not only the establishment of ethical restrictions, but also gives rise to the need to promptly resolve legal problems, including criminal and proce-dural ones. This is primarily due to the emergence and spread of legal expert systems that predict the decision on a particular case, based on a variety of parameters. Based on a comprehensive study, we formulate a definition of artificial intelligence suitable for use in law. It is proposed to understand artificial intelligence as systems capable of interpreting the received data, making optimal decisions on their basis using self-learning (adaptation). The main directions of using artificial intelligence in criminal proceedings are: search and generalization of judicial practice; legal advice; preparation of formalized documents or statistical reports; forecasting court decisions; predictive jurisprudence. Despite the promise of using artificial intelligence, there are a number of problems associated with a low level of reliability in predicting rare events, self-excitation of the system, opacity of the algorithms and architecture used, etc.

Although delusion is one of the central concepts of psychopathology, it stills eludes precise conceptualization. In this paper, I present certain basic issues concerning the classification and definition of delusion, as well as its ontological status. By examining these issues, I aim to shed light on the ambiguity of the clinical term ‘delusion’ and its extension, as well as provide clues as to why philosophers are increasingly joining the ranks of psychiatrists, psychologists, and neuroscientists in the effort to come to a comprehensive understanding of delusion.

This paper addresses the question of the definition of compounding from a terminological perspective. In terminology, concepts are defined by a selection of properties shared by prototypical cases. For scientific terminology, the selection is validated by the strength of the theories that can use the definition. It is shown that morphophonological criteria often adduced in the delimitation of compounding are not adequate in a universal definition. In order to come up with a better definition, a two-step procedure is proposed. In the first step, a universal definition is used to determine for constructions in a particular language whether they belong to compounding. In the second step, language-specific properties are used to identify instances of these constructions. A definition is proposed that takes a compound as a word with a binary, headed structure, a relation between the elements that is not determined by compounding and a non-head that is not introduced as an entity in the discourse. The use of this definition is illustrated with a number of constructions in different languages. It is shown that expressions commonly called exocentric and copulative compounds are generally not compounds in this definition, but that some expressions that have been labelled as such are in fact compounds. The two-step procedure demonstrated here for compounding can also be used for other linguistic terms.

The article attempted to analyse critically the definition of trauma as it is used in the Western medical and psychiatry contexts in order to come up with an appropriate African definition. This was undertaken with the view to demonstrate that the Western worldview is different from the African worldview. Superimposing solutions or providing pre-packed answers to unique African problems will lead only to re-traumatisation, whereas cultural sensitivity and the right diagnosis will lead to the correct treatment. The driving force behind this article was therefore to aim to be relevant, effective and contextual in all African-based pastoral care.
