Religious Poetry and Musical Performance under King HammurÄpi of Babylon and His Successors
Mit Beginn des 2. Jt. v. Chr. erlebt Mesopotamien einen historischen Wandel auf politischer, sozialer und religiöser Ebene. Aus dem Westen einwandernde so genannte amurritische Dynastien ĂŒbernehmen die politische Macht in Zentralbabylonien, wo sie ihr eigenes ,akkadi-schesâ Erbe begrĂŒnden. UrsprĂŒngliche sumerische Traditionen SĂŒdmesopotamiens werden dabei entweder aufrechterhalten, ĂŒberlagert oder aufgegeben. Vermehrt sind Neuerungen unter König HammurÄpi und seinen Nachfolgern zu verzeichnen. Basierend auf der keilschriftlichen Ăberlieferung werden in diesem Kapitel Wandlungsprozesse mit Auswirkungen auf die Tempel- und Hofmusik identiïŹziert und analysiert. Hierbei wird auch der Frage nach den Initiatoren solcher Prozesse und ihrer politischen wie kulturellen Motivation nachgegangen
Specimen poetics: botany, reanimation, and the Romantic collection
This essay argues that the modern literary anthologyâand specifically its aspiration to delimit both aesthetic merit and historical representativenessâemerged as a response to changes in eighteenth-century botanical collecting, description, and illustration. A dramatic upsurge in botanical metaphors for poetic collections around 1800 was triggered by shifts in the geographies, aims, and representational practices of botany in the previous century. Yoking Linnaean taxonomy and Buffonian vitalism to Hogarthâs line of beauty, late eighteenth-century botanical illustrations imbued plucked, pressed specimens with a new vitality. Erasmus Darwinâs Botanic Garden (1789, 1791) translated the aesthetic reanimations of visual art into a collection of poetic specimens, spurring compilations that promote a vitalist standard of literary value. By rejecting aesthetic reanimation as the figurative ground for poetic collecting, Charlotte Smith and Robert Southey forward an alternative historical model of literary merit, one grounded in the succession and continuity of representative literary types. These competing metrics for selection and valuation underwrite the anthology as we know it today
Worlds apart: Pictorial semantics in the left and right cerebral hemispheres
The dominant view in neuropsychology fails to consider that the
hemispheric "functional division of labor" in terms of language versus
non-language reflects but one dimension of hemispheric differences.
That is, specialization of language in the left hemisphere and of
spatial orientation in the right represent only specific aspects of the
general underlying hemispheric meaning systems. Indeed, we have found
that there can be two full-blown meaning systems, one in the left and
one in the right, which can operate separately and simultaneously in
the normal brain.
The case for a relationship between human memory, hippocampus and corpus callosum
Unilateral brain damage which includes the hippocampus leads to memory impairments consistent with hemispheric specialization on the same side. Damage to the corpus callosum, the major connecting pathway between the left and right hemispheres, also leads to memory impairments. This suggests both hemispheric specialization on the hippocampal level and a critical role for the corpus callosum in memory functions. A complete hippocampal formation is present on either side of the brain but traditionally only one is studied. However, a comparison between the neuronal populations in the hippocampus on both sides revealed asymmetry in connectivity among hippocampal subfields. The profile of memory impairments of commissurotomy (Âsplit-brainÂ) patients is described. The results are discussed in terms of a relationship between hippocampus and corpus callosum in humans. As hemispheric specialization evolved, inter-hippocampal connections became less important and the corpus callosum became prominent in memory functions
Quantitative morphology of human hippocampus early neuron development
Background: Previous findings in adults revealed significant hemispheric asymmetry in size of neuronal somata in hippocampal subfield CA2 (the Âresistant sectorÂ) with no age-related changes. Paucity of quantitative data on the developmental status of these Âprotected neurons has led to the investigation of their morphology in comparison to neurons in adjacent subfield CA3, bilaterally. Methods: Bilateral coronal sections from postmortem hippocampus, 24 and 76 weeks postmenstrual age (gestational age plus postnatal age) were studied. The neurons were digitized and measured on a computer. Results: Soma size correlated positively and significantly with age in CA2 and CA3, bilaterally. CA2 somata were significantly larger (left 34%, right 32%) than adjacent CA3 somata. Variability in soma form or size increased appreciably with age, in both subfields, bilaterally, while variability in soma orientation was weakly correlated with brain growth. Conclusions: The results suggest that in early development there are similarities in hemispheric growth patterns in CA2 and CA3. Large CA2 soma size implies axonal connectivity to distantly located targets very early in development. The results have functional implications, including memory, to brain developmen
A view of the world from a split-brain perspective
The extent to which observed behavior in the complete commissurotomy
patients is supported by only one hemisphere would depend on individual
differences interacting with a variety of factors such as genetics,
intelligence, and so on. The lesson imparted here is that there is
sufficient functional redundancy in the neocortex so that the capacity
to maintain a wide range of abilities is within the control of one
hemisphere. And, yet, as seen in what is missing in the patients'
behavior, one hemisphere is not quite enough. Nature seems to have
intended that the two hemispheres complement each other, that the full
range of human behavior be best accomplished through interaction
between the left and right hemispheres

Optimal Gossip with Direct Addressing
Gossip algorithms spread information by having nodes repeatedly forward
information to a few random contacts. By their very nature, gossip algorithms
tend to be distributed and fault tolerant. If done right, they can also be fast
and message-efficient. A common model for gossip communication is the random
phone call model, in which in each synchronous round each node can PUSH or PULL
information to or from a random other node. For example, Karp et al. [FOCS
2000] gave algorithms in this model that spread a message to all nodes in
rounds while sending only messages per node
on average.
Recently, Avin and Els\"asser [DISC 2013], studied the random phone call
model with the natural and commonly used assumption of direct addressing.
Direct addressing allows nodes to directly contact nodes whose ID (e.g., IP
address) was learned before. They show that in this setting, one can "break the
barrier" and achieve a gossip algorithm running in
rounds, albeit while using messages per node.
We study the same model and give a simple gossip algorithm which spreads a
message in only rounds. We also prove a matching lower bound which shows that this running time is best possible. In
particular we show that any gossip algorithm takes with high probability at
least rounds to terminate. Lastly, our algorithm can be
tweaked to send only messages per node on average with only
bits per message. Our algorithm therefore simultaneously achieves the optimal
round-, message-, and bit-complexity for this setting. As all prior gossip
algorithms, our algorithm is also robust against failures. In particular, if in
the beginning an oblivious adversary fails any nodes our algorithm still,
with high probability, informs all but surviving nodes
Guidance on the principles of language accessibility in National Curriculum Assessments : research background
This review accompanies the document, which describes the principles which should guide the development of clear assessment questions. The purpose of the review is to present and discuss in detail the research underpinning these principles. It begins from the standpoint that National Curriculum assessments, indeed any assessments, should be:
- appropriate to the age of the pupils
- an effective measure of their abilities, skills and concept development
- fair to all irrespective of gender, language, religion, ethnic or social origin or disability. (Ofqual, 2011)
The Regulatory Framework for National Assessments: National Curriculum and Early Years Foundation Stage (Ofqual, 2011) sets out a number of common criteria which apply to all aspects of the development and implementation of National Assessments. One of these criteria refers to the need for assessment procedures to minimise bias: âThe assessment should minimise bias, differentiating only on the basis of each learnerâs ability to meet National Curriculum requirementsâ (Section 5.39, page 16). The Framework goes on to argue that: âMinimising bias is about ensuring that an assessment does not produce unreasonably adverse outcomes for particular groups of learnersâ (Annex 1, page 29). This criterion reinforces the guiding principle that any form of assessment should provide information about the knowledge and understanding of relevant content material. That is to say that the means through which this knowledge and understanding is examined, the design of the assessment and the language used should as far as possible be transparent, and should not influence adversely the performance of those being assessed.
There is clearly a large number of ways in which any given assessment task can be presented and in which questions can be asked. Some of these ways will make the task more accessible â that is, easier to complete successfully â and some will get in the way of successful completion. Section 26 of the Fair Access by Design (Ofqual, 2010) document lists a number of guiding principles for improving the accessibility of assessment questions, although the research basis for these principles is not made completely clear in that document. The aim of the current review is to examine the research background more closely in order to provide a more substantial basis for a renewed set of principles to underpin the concept of language accessibility.
In the review, each section will be prefaced by a statement of the principles outlined in Guidance on the Principles of Language Accessibility in National Curriculum Assessments and then the research evidence underpinning these principles will be reviewed
Extreme empiricism: John Howard, poetry, and the thermometrics of reform
This essay examines an outpouring of printed poems and biographical publications in the 1780s and 1790s that sought to shape the public image of the celebrated prison reformer John Howard. These materials, we argue, reveal the ways in which reform, empiricism, and Christian charity reinforced each other in late eighteenth-century popular imagination, and how this conjunction provoked a new vision of Britainâs empire and a backlash against mixing the scientific and the miraculous. As we show, Howard used the language of temperature to turn empirical data into evidence for the necessity of prison reform. This same thermometric language underwrote panegyric poems that represented Howard as global emissary of British benevolenceâthe icon of a new kind of empire whose power was symbolized by nearly miraculous capacity to temper inhospitable climates. This body of exuberant poetry transmuted data-based reform and technological advances in ventilation into proselytical triumph, a conjunction that was met, after Howardâs dramatic, self-inflicted death, with charges of overheated religious enthusiasm. As a result, Howardâs medical acquaintance and collaborators posthumously defended the temperateness of Howardâs empirical methods while also labeling him an amateur data collector, the lowly helpmeet of the professional man of science. By tracing Howardâs appearance in printed poetry and periodical writing, this essay illuminates the uneasy yet potent imbrication of reform culture, colonialism, medicine, and discipline formation in the final decades of the eighteenth century
