This paper extends the dialogue of educational philosophy to the experience of beginners entering the teaching profession. Rather than impose the ideas of any specific philosopher or theorist, or indeed official standard, the exploration presented here owes its origins to phenomenology and the use of grounded theory. Working from a narrative data base and focussing on the knowing of name in the first instance, the authors develop their emergent ideas on self and identity in relation to children taught, through connection (...) to a wider literature that includes reference to Giddens, Illeris, Deleuze and Heidegger, for example. The paper is thus also an exercise in suggesting that research on practice by academics working in professional education, who are non-philosophers, can lead to constructive and relevant engagement with philosophy in developing theory from and about about practice, even though the approach, in the initial stages, may well be serendipitous and eclectic in nature.

Works by authors of the Romantic period have often been viewed primarily as expressions of escapism, disillusionment, or apostasy on the part of the writer. In contrast, Hoagwood shows that political repression had important effects on the production of Romantic texts. Far from disengaging from the political world, works by Wordsworth, Coleridge, Blake, Shelley, Hays, and Smith, written at a time when overt expression was dangerous, express their author's contentions with political repression through duplicitous meaning and figural terminology. By (...) emphasizing the material textuality of Romantic writing, Hoagwood provides a new model for interpretation in the tradition of countering "Romantic ideology." Hoagwood demonstrates how political pressures and the institutions of publishing helped to shape the meanings of Romantic texts. He argues for the importance of a book's historically specific and material form in influencing the way critics and scholars view a given work. Literary theory and textual criticism come together in this book to show the new ranges of significance that can emerge when a poetic work is studied as a material artifact. The study concludes with a comparative analysis of critical theory in the Romantic period and in our own, addressing ways in which the differences between modernity and romanticism have affected interpretations of Romantic works. Hoagwood suggests that the political forces shaped the formulations of philosophic questions concerning interpretation and fictionality in much the same way they influenced the writing of Romantic literature.

Contemporary policymakers, as their predecessors, continue to view nomadic people as a weak minority, and their way of life and raising livestock as a backward and inefficient paradigm. Wherever nomads are not the dominant group, the trend to settle them continues even today as in the past. This book describes the changes forced upon formerly nomadic groups and how they still attempt to maintain their traditional, social, and cultural practices in their new settings. The book deals with the several modes (...) of livelihood of these communities, including entrepreneurship, and demonstrates the impact of investment-oriented urbanization policies leading to eviction from ancestral lands, and hurdles for nomadic mobility, ultimately threatening their survival. The book illustrates how some groups like the Borana and the Maasai practice livelihood diversity and raise productive livestock, and how other groups migrate to urban centers in search of employment and remit money to family members left in the rural areas. The book aims to raise awareness among the research community, especially those who work on regional and demographic labor policies. It helps in understanding why society needs to help build business and livelihood strategies without harming the values of nomadic groups. (shrink)

Identification of non-coding RNAs (ncRNAs) has been significantly enhanced due to the rapid advancement in sequencing technologies. On the other hand, semantic annotation of ncRNA data lag behind their identification, and there is a great need to effectively integrate discovery from relevant communities. To this end, the Non-Coding RNA Ontology (NCRO) is being developed to provide a precisely defined ncRNA controlled vocabulary, which can fill a specific and highly needed niche in unification of ncRNA biology.

This contribution grapples with the question: Is there a relationship between Steve Biko’s ‘quest for a true humanity’ or, differently put, his search for South Africa’s ‘human face’ and Vuyani Vellem’s quest for an African spirituality? Our proposition is that there is such a relationship. This discussion is framed overall by two other questions: What is the relevance of this ‘quest’ within the present South African context, what is its contribution to the global situation and, fundamentally, what is the contribution (...) black liberation theology can make to these discourses? In the course of this exploration, we engage the concepts of Africanisation and Afrocentricity, colonisation, coloniality and decoloniality, and we ask whether a true Afro-pluralism is possible without a true African indigeneity. These concepts, we shall argue, are tools of struggle, not only in confronting colonisation and coloniality but also in battling imperialism, in the form I discuss here: the politics of vulgarity. I contend that an African spirituality, Biko’s ‘gift’ from Africa to the world, is the most appropriate vessel for that very gift.Contribution: This article serves as commemoration of the contribution the late Professor Vuyani Vellem made to the qualitative substantiation of black theology liberation in South Africa. It demonstrates the powerful way in which Afro-pluralism enhances the contra-narrative of imperialism and colonialism. (shrink)

The assassination of Martin Luther King Jr, 50 years ago on 04 April 1968, has been recalled in the United States with memorial services, conferences, public discussions and books. In contrast, the commemoration in 2017 of the death of Albert John Mvumbi Luthuli, 50 years ago on December 1967, passed almost unremarked. That is to our detriment. Yet, these two Christian fighters for freedom, in different contexts, did not only have much in common, but they also left remarkably similar and (...) equally inspiring legacies for South Africa, the United States and the world in the ways they lived their lives in complete faith commitment to ideals and ways of struggle that may guide us in the ongoing struggles to make the world a more just, peacable and humane place. For South African reflections on our ethical stance in the fierce, continuing struggles for justice, dignity and the authenticity of our democracy, I propose that these two leaders should be considered in tandem. We should learn from both. This article engages Martin Luther King Jr’s belief in the ‘inescapable network of mutuality’, applies it to the struggle for freedom in South Africa and explores the ways in which South Africans can embrace these ethical ideals in facing the challenges of post-liberation.

This article examines the manner and method of resistance against patriarchal power and privilege. Two types of power are contrasted. One is the violent, war-like and hierarchical power of an empire, and the other is the faithful resistance of Israel's prophets. A further distinction is made between violent male power and non-violent female power. It is argued that Miriam was a prophet of the people and her prophetic witness is an example of the power and outcome of non-violent resistance. Her (...) theology explicitly and specifically praises God not as a warrior. Hers is not a muscular, masculine God whose power seeks to match the power of empire. Her God has a power that through radical love for a slave people and taking sides with the enslaved overcomes the power of the slaveholder. In her theology, Miriam recalls the God of the exodus, who begins the acts of liberation with the women, to whose faithfulness, courage and defiant obedience, the freedom of the people is entrusted. From a feminist perspective it is argued that this style of non-violent, faithful prophetic witness has a greater impact than violent resistance associated with an empire-like power. It is suggested that black liberation theology should adopt this paradigm in its witness of and resistance against oppression. (shrink)

This book examines some of the deepest questions in philosophy: What is involved in judging a belief, action, or feeling to be rational?

"The Blackwell Guide to Philosophy of Education" is state-of-the-art map to the field as well as a valuable reference book.

Choices can be wise or foolish, and feelings can be apt or off the mark. So we judge, and it would be good to know what content these normative judgements carry. Gibbard offers an answer, and elaborates it. His theory explores what is at issue in narrowly moral questions, and in questions of rational thought and conduct in general.

Classic voltaic batteries of the silver/zinc and copper/zinc types are the ancestors of today's primary cells, and facilitated the development of many aspects of electrical technology. Nevertheless, they appear never to have been studied and evaluated in a quantitative manner, with results recorded in terms of volts, amps, ohms, and watts. Research of this nature is reported here, and has been conducted for the most part with copper/zinc cells. Log–log graphs of voltage versus load and current, and power versus load, (...) are presented for many electrolyte systems. It has been shown that, although the textbook electrolyte of dilute sulphuric acid does work, it is an order of magnitude inferior to a solution containing some additional nitric acid. The latter diminishes the current‐limiting phenomenon of polarization, and was in fact used by Davy, Faraday, and other early investigators. A quantitative consideration of Nicholson and Carlisle's discovery of the electrolysis of water with a silver/zinc voltaic pile is followed by examination of the electrolysis of pure water, trough batteries, and Davy's isolation of potassium and sodium. Every battery gives maximum power when its resistance is adjusted to match the resistance of the load: the maximum output of the ‘Great Battery’ of the Royal Institution is assessed at no more than 3 kW. The paper concludes with a note on the recognized hazard of long‐term exposure to mercury vapour and its possible relevance to the health of Michael Faraday. (shrink)

This paper examines the various types of small, portable heliostat which maintain a beam of sunlight in a constant direction. Used mainly in the second half of the nineteenth century, these instruments were intended for optical demonstrations and the illumination of microscopes and similar apparatus, rather than for astronomical applications. Three basic patterns are distinguished: polar heliostats , biaxial single-mirror heliostats, and coelostats. The theory and geometry of each type is explained, followed by a consideration in chronological order of the (...) corresponding working instruments. Heliostats by Fahrenheit, Meyerstein, 's Gravesande, Gambey, Silbermann, Foucault, Stoney and others are illustrated, and extensive references given. (shrink)

The true form of the seasonal-hour sundial, in both vertical and horizontal planes, has been calculated by spherical trigonometry and displayed with the aid of computer graphics. These grids are presented, and show that the hour lines are in fact shallow curves at sites not on the equator. The curvature becomes very apparent at latitudes exceeding 50°. The true seasonal-hour pattern for a vertical dial at a latitude of 52·6°N is compared with the equiangular scratch dial.

In the early 1800s galvanometers could be constructed with the fine gauges of silk-covered copper or silver wires produced for decorative purposes, but when Faraday was making his classic electrical experiments in 1831 he needed a sturdier gauge of copper wire. Bare copper wire was available in many diameters for mechanical applications, but coils for electromagnetic investigations had to be insulated with string and calico. It was soon realized that the cotton-covered springy iron wire then used to hold out the (...) brims of ladies' bonnets showed how copper wire might be similarly wrapped to provide a flexible insulation. The simple manual machines used by the bonnet-wire makers were readily adapted and improved, and a six-head version was built by William Henley. This craftsman's vision of the growing importance of insulated copper wire was abundantly justified, and he built up a large—but poorly organised—empire in the wire and cable trade. Henley's original multiple-head wrapping machine has been located in the Science Museum, London, and the associated silk-covered copper wire subjected to physical, chemical, and electrical testing. For comparison, the electrical conductivity of the ‘mechanical grade’ copper wire used by Faraday has also been determined. (shrink)

The lodestone is an extremely rare form of the mineral magnetite that occurs naturally as a permanent magnet. It therefore attracts metallic iron as well as fragments of ordinary ‘inert’ magnetite. This ‘magic’ property was known to many ancient cultures, and a powerful lodestone has always commanded a high price. By the eleventh century AD the Chinese had discovered that a freely suspended elongated lodestone would tend to set with its long axis approximately north–south, and utilized this property in the (...) magnetic compass. They also appear to have discovered that this invaluable characteristic could be handed‐on to a steel needle if the latter were contacted with, or stroked by, a lodestone.The magnetism of the lodestone was scientifically investigated by William Gilbert in the sixteenth century, when he defined its ‘poles' and the well‐known rule that ‘like poles repel, unlike attract’. He also studied ‘inclination’ and ‘variation’, and means to aid the preservation of magnetic power. How to concentrate it by ‘arming’ the lodestone with caps or pole‐pieces of soft iron was discovered in the same century. These methods have been repeated, confirmed, and improved. The lodestone occupies a vital place in the history of magnetism, but little beyond Gilbert's work can be reached by historical studies because vastly improved steel or alloy permanent magnets, and electromagnets, replaced it before quantitative measurements were developed. These techniques have therefore been applied retrospectively to both museum specimens and contemporary natural lodestones. A good source of the latter was found to be the igneous complex known as Magnet Cove, Arkansas, and this material has been used as the ‘type example’. All specimens were discrete, well‐rounded, rusty brown pebbles found near the surface. Their unweathered interiors were black titanomagnetite. No significant trace element or crystallographic differences could be found between the lodestones and the magnetically inert material that always accompanied them. The magnetic moment per unit volume of the ‘as‐found’ Magnet Cove lodestones varied between 6.5 and 11.6 emu cm−3, which compares poorly with the hundreds of units characteritzing modern permanent magnets. Hysteresis loops gave a saturation intensity of 27–51 emu cm−3, suggesting that intensity has diminished since formation. This agrees with general experience of magnets, especially in the absence of a ‘keeper’. The initial volume susceptibility of Magnet Cove magnetite was about 0.18 for low fields, and always remained <1. This means that a normal terrestrial magnetic field with a maximum vector <1 Oe is unable to induce even the low magnetic moments we see today, while a field approaching 1000 Oe is required for saturation. These parameters, and the rare occurrence of lodestones as near‐surface fragments, support suggestions that they are the product of a lightning strike upon an exposure of a suitable magnetite. Transient currents averaging 30 000 A have been measured. This would give rise to a zone of potential magnetic saturation at least 12 cm in diameter, to which some of the ejected fragments would be exposed. An attempt to determine the period elapsed since formation of the Magnet Cove lodestone was made by annealing magnetically saturated specimens at temperatures up to 500°C, and measuring J v at weekly intervals for 100 days. The decay curves visually resembled exponential functions, but mathematical tests proved that they were not strictly so. Interpretation was therefore difficult, but a pragmatic procedure involving excessive extrapolation suggested an ‘age’ of about 3500 years. (shrink)

This article demonstrates that Tacitus, who coined the term interpretatio Romana, used this concept differently than today's historians of religion. Tacitus differentiated between universal and local gods. It is also shown that this differentiation fits the author's structuring of "Germania", which he divides into a general and a specific part. This carries far-reaching consequences because for instance the cult of the Semnones is a local superstitio in tacitean terms, and the common identification of Roman with ”Germanic“ gods since J. Grimm (...) must be abandoned. Finally, the article establishes that G. Wissowa's seminal work on interpretatio Romana, which assumes the deity cults of Germania superior and inferior, fails to take into account that Tacitus, as a historian of religion, merely dealt with "authentic" and "original" Germania.

The following article shows what Tacitus Ann. 15,44 thought of the role of the Chrestiani at the burning of the Roman capital A.D. 64 and why they themselves as punishment of their,,crime“ were crucified and burned. In order to demonstrate this the textus receptus is first analysed linguistically and its content interpreted in its historical and sociological context. It is ethnohistorically established as a fact that Tacitus counted the Chrestiani as a minority of the Iudaei. Linguistically it is proved that (...) the words aut flammandi atque ubi are corrupt and have to be emended ad flammas dati, ut, cum why some of the Chrestiani as part of their punishment were given to the flames, i.e. Latine: ad flammas dati.

A brief self-report scale was developed to assess everyday performance failures arising directly or primarily from brief failures of sustained attention . The ARCES was found to be associated with a more direct measure of propensity to attention lapses and to errors on an existing behavioral measure of sustained attention . Although the ARCES and MAAS were highly correlated, structural modelling revealed the ARCES was more directly related to SART errors and the MAAS to SART RTs, which have been hypothesized (...) to directly reflect the lapses of attention that lead to SART errors. Thus, the MAAS and SART RTs appear to directly reflect attention lapses, whereas the ARCES and SART errors reflect the mistakes these lapses are thought to cause. Boredom proneness was also assessed by the BPS, as a separate consequence of a propensity to attention lapses. Although the ARCES was significantly associated with the BPS, this association was entirely accounted for by the MAAS, suggesting that performance errors and boredom are separate consequences of lapses in attention. A tendency to even extraordinarily brief attention lapses on the order of milliseconds may have far-reaching consequences not only for safe and efficient task performance but also for sustaining the motivation to persist in and enjoy these tasks.
