A revision of the Upper Jurassic-Lower Cretaceous dragonfly family Tarsophlebiidae, with a discussion on the phylogenetic positions of the Tarsophlebiidae and Sieblosiidae (Insecta, Odonatoptera, Panodonata)

The Upper Jurassic-Lower Cretaceous dragonfly family Tarsophlebiidae is revised. The type species of the type genus Tarsophlebia Hagen, 1866, T eximia (Hagen, 1862) from the Upper Jurassic Solnhofen Limestones, is redescribed, including important new information on its head, legs, wings, anal appendages and male secondary genital apparatus. The type specimen of Tarsophlebiopsis mayi Tillyard, 1923 is regarded as an aberrant or unusually preserved Tarsophlebia eximia. One new species of Tarsophlebia and three new species of Turanophlebia are described, i.e. Tarsophlebia minor n. sp., Turanophlebia anglicana n. sp., T mongolica n. sp., and T. vitimensis n. sp. A new combination is proposed for Turanophlebia neckini (Martynov, 1927) n. comb. The phylogenetic relationships of the Mesozoic Tarsophlebiidae are discussed on the basis of new body and wing venation characters. The present analysis supports a rather derived position for the Tarsophlebiidae, as sister group of the the Epiproctophora rather than of (Zygoptera + Epiproctophora). Also, through the present discussion, the Oligo-Miocene family Sieblosiidae seems to be more closely related to the Epiproctophora than to the Zygoptera. But the present study and previous analyses suffer of the lack of informations concerning the more inclusive groups of Odonatoptera, viz. Protozygoptera, Triadophlebiomorpha, Protanisoptera, etc. The significance of the tarsophlebiid secondary male genital apparatus for the reconstruction of the evolution of odonate copulation is discussed.

Governmentality, subject-building, and the discourses and practices of devolution in the UK

This paper uses a Foucauldian governmentality framework to analyse and interrogate the discourses and strategies adopted by the state and sections of the business community in their attempts to shape and influence emerging agendas of governance in post-devolution Scotland. Much of the work on governmentality has examined the ways in which governments have developed particular techniques, rationales and mechanisms to enable the functioning of governance programmes. This paper expands upon such analyses by also looking at the ways in which particular interests may use similar procedures, discourses and practices to promote their own agendas and develop new forms of resistance, contestation and challenge to emerging policy frameworks. Using the example of business interest mobilization in post-devolution Scotland, it is argued that governments may seek to mobilize defined forms of expertise and knowledge, linking them to wider political debates. This, however, creates new opportunities for interests to shape and contest the discourses and practices of government. The governmentalization of politics can, therefore, be seen as more of a dialectical process of definition and contestation than is often apparent in existing Foucault-inspired writing.

Too much information? : Drama teachers’ perceptions of the value of subject knowledge

This paper reports on research into what drama teachers consider they really need to know as drama specialists. In the first instance the very concept of knowledge is discussed as it pertains to education in the arts as is the current situation in England regarding the extent to which new drama teachers’ subject specialist knowledge has been formally accredited and what the implications of this may be to an evolving curriculum. The research itself initially involved using a questionnaire to investigate the way in which drama teachers prioritised different aspects of professional knowledge. Results of this survey were deemed surprising enough to warrant further investigation through the use of interviews and a multiple-sorting exercise which revealed why the participants prioritised in the way they did. Informed by the work of Bourdieu, Foucault and Kelly, a model is proposed which may help explain the tensions experienced by drama teachers as they try to balance and prioritise different aspects of professional knowledge.

Resilience or resistance? The value of subject knowledge for drama teachers

This paper reports on research undertaken by the author into what secondary school drama teachers think they need to possess in terms of subject knowledge in order to operate effectively as subject specialists. ‘Subject knowledge’ is regarded as being multi faceted and the paper reports on how drama teachers prioritise its different aspects. A discussion of what ‘subject knowledge’ may be seen to encompass reveals interesting tensions between aspects of professional knowledge that are prescribed by statutory dictate and local context, and those that are valued by individual teachers and are manifest in their construction of a professional identity. The paper proposes that making judgements that associate propositional and substantive knowledge with traditionally held academic values as ‘bad’ or ‘irrelevant’ to drama education, and what Foucault has coined as ‘subjugated knowledge’ (i.e. local, vernacular, enactive knowledge that eludes inscription) as ‘good’ and more apposite to the work of all those involved in drama education, fails to reflect the complex matrices of values that specialists appear to hold. While the reported research focused on secondary school drama teachers in England, Bourdieu’s conception of field and habitus is invoked to suggest a model which recognises how drama educators more generally may construct a professional identity that necessarily balances personal interests and beliefs with externally imposed demands.

C---H local modes in cyclobutene, part I: FTIR studies, 600 to 10000 cm–1

The vibrational structure of C---H stretching states in gas-phase cyclobutene was studied using FTIR spectroscopy in the range 700–9000 cm−1. The structure was modelled using two effective vibrational Hamiltonians, one for each type of C---H bond present, consisting of local mode basis functions subject to coupling with symmetrically equivalent bonds and to Fermi resonances with suitable low frequency vibrations. Best-fit model parameters were determined using least-squares routines and the model predictions are compared to the observed band positions and intensities. Some discussion is given of the relevance of the observed couplings to intramolecular vibrational redistribution (IVR) which results in the observation of statistical behaviour in cyclobutene isomerization induced by excitation of C---H stretching overtones in the visible region.

Antecedent priming at trace positions in children's sentence processing

The present study examines whether children reactivate a moved constituent at its gap position and how children's more limited working memory span affects the way they process filler-gap dependencies. 46 5-7 year-old children and 54 adult controls participated in a cross-modal picture priming experiment and underwent a standardized working memory test. The results revealed a statistically significant interaction between the participants' working memory span and antecedent reactivation: High-span children (n = 19) and high-span adults (n = 22) showed evidence of antecedent priming at the gap site, while for low-span children and adults, there was no such effect. The antecedent priming effect in the high-span participants indicates that in both children and adults, dislocated arguments access their antecedents at gap positions. The absence of an antecedent reactivation effect in the low-span participants could mean that these participants required more time to integrate the dislocated constituent and reactivated the filler later during the sentence.

Objects and positions in visual scenes: effects of perirhinal and postrhinal cortex lesions in the rat

The authors assessed rats' encoding of the appearance or egocentric position of objects within visual scenes containing 3 objects (Experiment 1) or I object (Experiment 2A). Experiment 2B assessed encoding of the shape and fill pattern of single objects, and encoding of configurations (object + position, shape + fill). All were assessed by testing rats' ability to discriminate changes from familiar scenes (constant-negative paradigm). Perirhinal cortex lesions impaired encoding of objects and their shape; postrhinal cortex lesions impaired encoding of egocentric position, but the effect may have been partly due to entorhinal involvement. Neither lesioned group was impaired in detecting configural change. In Experiment 1, both lesion groups were impaired in detecting small changes in relative position of the 3 objects, suggesting that more sensitive tests might reveal configural encoding deficits.
