Neuronal aggregates involved in conscious awareness are not evenly distributed throughout the CNS but comprise key components referred to as the neural network correlates of consciousness (NNCC). A critical node in this network is the posterior cingulate, precuneal, and retrosplenial cortices. The cytological and neurochemical composition of this region is reviewed in relation to the Brodmann map. This region has the highest level of cortical glucose metabolism and cytochrome c oxidase activity. Monkey studies suggest that the anterior thalamic projection likely (...) drives retrosplenial and posterior cingulate cortex metabolism and that the midbrain projection to the anteroventral thalamic nucleus is a key coupling site between the brainstem system for arousal and cortical systems for cognitive processing and awareness. The pivotal role of the posterior cingulate, precuneal, and retrosplenial cortices in consciousness is demonstrated with posterior cingulate epilepsy cases, midcingulate lesions that de-afferent this region and are associated with unilateral sensory neglect, observations from stroke and vegetative state patients, alterations in blood flow during sleep, and the actions of general anesthetics. Since this region is critically involved in self reflection, it is not surprising that it is similarly a site for the NNCC. Interestingly, information processing during complex cognitive tasks and during aversive sensations such as pain induces efforts to terminate self reflection and result in decreased processing in posterior cingulate and precuneal cortices.

The origin and the development of scientific disciplines has been a topic of reflection for several decades. The few extensive case studies support the thesis that scientific disciplines are not monolithic structures but can be characterized by distinct social, organizational and scientific–technical practices. Nonetheless, most disciplinary histories of genetics confine themselves largely to an uncontested account of the content of the discipline or occasionally institutional factors. Little attention is paid to the large number of researchers who, by their joint efforts, (...) ultimately shaped the discipline. We contribute to this aspect of disciplinary historiography by discussing the role of women researchers at the Institute for Heredity Research, founded in 1914 in Berlin under the directorship of Erwin Baur, and the sister of the John Innes Institute at Cambridge. This paper investigates how and why Baur built a highly successful research programme that relied on the efforts of his female staff, whose careers, notably Elisabeth Schiemann's, are also assessedin toto. These women undertook the necessary ‘technoscience’ and in some cases innovative work and helped increase the prestige of the institute and its director. Together they played a pivotal role in the establishment of genetics in Germany. Without them the discipline would have developed much more slowly and along a divergent path. (shrink)

The Theory of Multidimensional Reality is the latest development of this information theory of existence by the Author. The book applies the theory to explain what causes light, gravity, time, Planck's constant, and other phenomena found in physics. The Theory provides a foundation philosophy for all of science to explain some of the hardest phenomenon found.

Research into child language reveals that it takes a long time for children to learn the correct mapping of colour words. Steels & Belpaeme's (S&B's) guessing game, however, models fast learning of words. We discuss computational studies based on cross-situational learning, which yield results that are more consistent with the empirical child language data than those obtained by S&B.

This new edition of Introduction to Lattices and Order presents a radical reorganization and updating, though its primary aim is unchanged. The explosive development of theoretical computer science in recent years has, in particular, influenced the book's evolution: a fresh treatment of fixpoints testifies to this and Galois connections now feature prominently. An early presentation of concept analysis gives both a concrete foundation for the subsequent theory of complete lattices and a glimpse of a methodology for data analysis that is (...) of commercial value in social science. Classroom experience has led to numerous pedagogical improvements and many new exercises have been added. As before, exposure to elementary abstract algebra and the notation of set theory are the only prerequisites, making the book suitable for advanced undergraduates and beginning graduate students. It will also be a valuable resource for anyone who meets ordered structures. (shrink)

Georgians' acquaintance with Islam was with the first Arab raids. From the first Muslim Arab domination, Georgians started to become Muslims with cultural interaction. Islam spread especially in Eastern Georgia during the time of Muslim Arabs, Seljuks and Mongols. The spread of Islam in Western Georgia started with the Ottomans. The Ottoman Empire's contact with Georgia begins with the conquest of Trabzon by Fatih Sultan Mehmed. When the Ottomans contacted the region, the geography of Georgia was divided into small kingdoms. (...) With the conquest of Trabzon, the Georgian border was reached and in 1479, Acaristan, Borcka and Maçahel surroundings joined the Ottoman lands. On the one hand, Sukhumi was captured from the north. Then, continuing to advance in the region, Yavuz Sultan Selim paid tribute to the Kingdom of Güryel and Imeret (Açıkbaş) in 1508 during his governorship of Trabzon. Thus, the Ottoman borders had reached beyond the Black Sea coast into Western Georgia. As a result of the increasing relations around Adjaria, which came under Ottoman rule, Islamization began to spread rapidly among the people. Contrary to what is claimed, the spread of Islam in the region did not spread from the ruling strata to the lower, but from the popular strata to the ruling strata. This process was surprisingly fast. In the process of Islamization, many mosques, masjids and schools were built in Adjara, especially with the help of the people. The foundations operating in the region and the mosques and masjids serving under them show that, contrary to the claims of Russian and Georgian historians, Islamization took place rapidly at the beginning of the 17th century in Adjara. In this process, many mosques, masjids and schools were built in the region. In this research, based on the numerous Hurufat records belonging to Adjara, Batumi, Gönye, Çürüksu and Maçahel, the Islamization process will be evaluated by making a social reading with the data obtained from the religious structures established in the rural settlements of the Adjara geography and their officials. Evaluations were made on the Islamization process in Adjara by making a social reading. (shrink)

Sections R1 to R3 attempt to take the sting out of hostile commentaries. Sections R4 to R5 engage Berlin and Kay and the World Color Survey to correct the record. Section R6 begins the formulation of a new theory of colour as an engineering project with a technological developmental trajectory. It is recommended that the colour space be abandoned.

In this target article the following hypotheses are discussed: (1) Colour is autonomous: a perceptuolinguistic and behavioural universal. (2) It is completely described by three independent attributes: hue, brightness, and saturation: (3) Phenomenologically and psychophysically there are four unique hues: red, green, blue, and yellow; (4) The unique hues are underpinned by two opponent psychophysical and/or neuronal channels: red/green, blue/yellow. The relevant literature is reviewed. We conclude: (i) Psychophysics and neurophysiology fail to set nontrivial constraints on colour categorization. (ii) Linguistic (...) evidence provides no grounds for the universality of basic colour categories. (iii) Neither the opponent hues red/green, blue/yellow nor hue, brightness, and saturation are intrinsic to a universal concept of colour. (iv) Colour is not autonomous. (shrink)
