"No Artist has Ethical Sympathies": Oscar Wilde, Aesthetics, and Moral Evolution

“There is no mode of action, no form of emotion, that we do not share with the lower animals” (137). This evolutionary claim is not attributable to Darwin, but to Oscar Wilde, who allows Gilbert to voice this bold assertion in “The True Function of Criticism.” While critics have long wrestled with the ethical stance and coherence of Wilde's writings, they have overlooked a significant influence on his work: debates concerning the evolution of morality that animated the periodicals in which he was writing. Wilde was fascinated by the proposition that complex human behaviours, including moral and aesthetic responses, might be traced back to evolutionary impulses. Significantly, he also wrote for a readership already engaged with these controversies.

Preparing medical students for normal birth: an interactive workshop by pre-registration midwifery students.

There is an increasing recognition of the need to improve inter professional relationships within clinical practice (DoH, 2001). Evidence supports the assertion that health care professionals who are able to communicate and work effectively together and who have a mutual respect and understanding for one another’s roles will provide a higher standard of care (McPherson et al, 2001; Begley, 2008). Providing inter professional education within a University setting offers an opportunity for a non-threatening learning environment where students can develop confidence and build collaborative working relationships with one another (Saxell et al, 2009).
An inter-professional education initiative was developed in Queen’s University Belfast within the Schools of Nursing and Midwifery and Medicine and piloted in 2014. The aim of the collaboration was to introduce concepts of normal labour and birth to fourth year medical students prior to their obstetric and gynaecological placement in hospital. The teaching staff felt this would be an excellent opportunity for final year pre-registration midwifery students to demonstrate their knowledge and understanding on normality in labour and birth by preparing interactive workshops with the medical students. The midwifery students were provided with an outline agenda in relation to content for the workshop, but then were allowed creative licence with regard to delivery of the workshop. The workshops consisted of approximately 4 midwifery students to 12 medical students. Resources such as birthing balls, birth mannequins, dolls and pelvises were available to the students to increase interactivity. Significant emphasis was placed upon the importance of relationship building with women in labour and the concept of being ‘with woman’ was core to all elements of teaching. Midwifery students undertook acting roles such as the labouring woman, partner or a midwife role and acted out mini scenarios such as contacting for advice about early labour; positions for labour or positions for birth. Medical students were prompted to vocalise about their feelings towards labour and birth and encouraged to think about their role within the birth setting.
Preliminary evaluations of the workshops have been extremely positive from both the midwifery students and the medical students. The midwifery students have commented on the enjoyable aspects of team working for preparing for the workshop and also the confidence gained from teaching the medical students. The medical students have evaluated the teaching by the midwifery students positively and felt that it lowered their anxiety going into the labour setting. A number of midwifery and medical students have subsequently worked with one another within the practice setting which has been recognised as beneficial. Both Schools have recognised the benefits of this form of inter professional education and have subsequently made a commitment to embed it within each curriculum.

Innovative interprofessional teaching session on labour and childbirth for undergraduate medical and midwifery students

There is an increasing recognition of the need to improve interprofessional relationships within clinical practice (Midwifery 2020, 2010). Evidence supports the assertion that healthcare professionals who are able to communicate and work effectively together and who have a mutual respect and understanding for one another’s roles will provide a higher standard of care (McPherson et al, 2001; Miers et al, 2005; Begley, 2008). The joint Royal College of Obstetrics & Gynaecologists(RCOG) / Royal College of Midwives (RCM) report (2008 Page 8) on clinical learning environment and recruitment recommended that “Inter-professional learning strategies should be introduced and supported at an early stage in the medical and midwifery undergraduate students' experience and continued throughout training.” Providing interprofessional education within a University setting offers an opportunity for a non-threatening learning environment where students can develop confidence and build collaborative working relationships with one another (Saxell et al, 2009).Further research supports the influence of effective team working on increased client satisfaction. Additionally it identifies that the integration of interprofessional learning into a curriculum improves students’ abilities to interact professionally and provides a better understanding of role identification within the workplace than students who have only been exposed to uniprofessional education (Meterko et al, 2004; Pollard and Miers, 2008; Siassakos, et al, 2009; Wilhelmsson et al, 2011; Murray-Davis et al, 2012). An interprofessional education indicative has been developed by teaching staff from the School of Nursing and Midwifery and School of Medicine at Queen’s University Belfast. The aim of the collaboration was to enhance interprofessional learning by providing an opportunity for medical students and midwifery students to interact and communicate prior to medical students undertaking their obstetrics and gynaecology placements. This has improved medical students placement experience by facilitating them to learn about the process of birth and familiarisation of the delivery suite environment and it also has the potential to enhance interprofessional relationships. Midwifery students benefit through the provision of an opportunity to teach and facilitate learning in relation to normal labour and birth and has provided them with an opportunity to build stronger and more positive relationships with another profession. This opportunity also provides a positive, confidence building forum where midwifery students utilise teaching and learning strategies which would be transferable to their professional role as registered midwives. The midwifery students were provided with an outline agenda in relation to content for the workshop, but then were allowed creative licence with regard to delivery of the workshop. The interactive workshops are undertaken within the University’s clinical education centre, utilising low fidelity simulation. The sessions are delivered 6 times per year and precede the medical students’ obstetric/gynaecology placement. All 4th year medical and final year midwifery students have an opportunity to participate. Preliminary evaluations of the workshops have been positive from both midwifery and medical students. The teaching sessions provided both midwifery and medical students with an introduction to inter professional learning and gave them an opportunity to learn about and respect each other’s roles. The midwifery students have commented on the enjoyable aspects of team working for preparing for the workshop and also the confidence gained from teaching medical students. The medical students have evaluated the teaching by midwifery students positively and felt that it lowered their anxiety levels going into the labour setting. A number of midwifery and medical students have subsequently worked with one another within the practice setting which has been recognised as beneficial. Both Schools have recognised the benefits of interprofessional education and have subsequently made a commitment to embed it within each curriculum.

Invention and uninvention in nuclear weapons politics

If there is one uncontroversial point in nuclear weapons politics it is that uninventing nuclear weapons is impossible. This article seeks to make this claim controversial by showing that it is premised on attenuated understandings of invention and the status of objects operative through familiar but problematic conceptual dualisms. The claimed impossibility of uninvention is an assertion that invention is irreversible. Drawing on “new materialism” this article produces a different understanding of invention, reinvention, and uninvention as ontologically similar practices of techno-political invention. On the basis of empirical material on the invention and re-invention of nuclear weapons, and an in-depth ethnography of laboratories inventing a portable radiation detector, both the process of invention and the “objects” themselves (weapons and detectors) are shown to be fragile and not wholly irreversible processes of assembling diverse actors (human and non-human) and provisionally stabilizing their relations. Nuclear weapons cannot be uninvented! Why not?

‘At First I Saw It as a Toy’: Life Stories, Social Consciousness and Music Ethnography

This article examines the role of life narratives as discursive spaces for the performance of individual resistance. Through the inspection of three interviews with professional musicians in Athens, the essay will illustrate how the recounting of nodal events in their lives and careers facilitates an assertion of their current social ideology and their disillusionment with the popular music industry in which they operate. Ultimately, what follows will suggest a mode of listening to individual utterances and narratives as discursive forms of resistance that need to be appreciated as social acts as opposed to mere ethnographic data.

Marcas portuguesas: uma metodologia para a afirmação e avaliação dos seus impactos

O processo de criação de marcas – branding – decorre da intervenção de um diversificado número de especialistas de áreas científicas distintas como são: a da comunicação, da publicidade, do marketing e das relações públicas. O designer, apesar de ser um dos mais significantes actores no processo de construção da marca é, geralmente, relegado para o plano de fazedor das coisas esteticamente úteis. As razões deste facto podem ser encontradas neste estereótipo que constrange o entendimento sobre a vocação do designer, desvalorizando- se o seu papel de conceptualizador e não respeitando os seus argumentos. A flexibilidade do seu pensar analítico, criativo e sistémico associado à acção direccionada para a mudança leva à consideração de que o Designer é um agente multifacetado e, numa equipa, é um membro agregador de diversas sensibilidades. A síntese que opera através do desenho permite ao designer colocar-se numa posição de dinamização e, porventura, de liderança de carácter identitário. Tendo em conta o exposto o designer necessita de metodologias de apoio ao seu desempenho que lhe permitam realizar o trabalho para o qual está vocacionado. Enquadrado pela lógica sistémica da comunicação institucional, essas metodologias potenciam a observação, análise e avaliação da marca, uma vez que está focalizada na recolha das orientações dos destinatários da marca – cidadãos e consumidores. Conhecer como percepcionam a marca, qual a relação que mantêm com ela e como reagem à forma como a marca comunica é o desafio da metodologia criada. Deste modo, o designer poderá contribuir para a desconstrução dos estereótipos referidos, reforçar a sua posição no mercado de trabalho e afirmar a sua diferença face aos especialistas das áreas complementares com quem intervém. A tese que se apresenta tem por finalidade elaborar uma metodologia para a afirmação e avaliação dos impactos da marca, no sentido de conhecer as orientações de quem melhor sabe lidar com a marca - o público-alvo. E, integrar toda a informação no processo decisão que o designer protagoniza.

Formação cívica e formação de professores: limites e potencialidades

A reorganização curricular do Ensino Básico de 2001 representou uma mudança de paradigma: uma aposta na flexibilidade, na integração e na autonomia. Uma das principais inovações desta reforma foi a criação de áreas curriculares não disciplinares, entre elas a Formação Cívica. Uma década volvida qual o impacto desta decisão? Estudos anteriores revelaram o uso administrativo e burocrático da Formação Cívica, ao serviço do Diretor de Turma e das suas responsabilidades de gestão da turma e resolução de conflitos. Num cenário de defraudamento das expetativas iniciais depositadas neste domínio não disciplinar e convencidos que estávamos da importância de potenciar espaços reais de promoção da Cidadania nas escolas desencadeámos um estudo de modelização dupla investigação-formação que nos permitisse compreender qual o papel da formação de professores neste domínio e os respetivos limites e potencialidades da Formação Cívica. Com base no pressuposto de que a ação de qualquer professor em contexto de sala de aula depende do conhecimento profissional que possui acerca de um determinado domínio curricular e reconhecendo a ausência de mecanismos de formação específica para a concretização dos tempos letivos de Formação Cívica, estruturámos o nosso trabalho com o intuito de contribuir para a construção de conhecimento sobre a natureza da formação de professores em Formação Cívica. Realizado no contexto da formação contínua de professores, o presente estudo desenvolveu-se em duas etapas fundamentais que se foram interligando entre momentos de investigação, reflexão, formação, recolha e análise de dados. A abordagem metodológica que se delineou para todas as fases assumiu um cariz qualitativo e crítico-interpretativo. Numa primeira fase, realizámos um estudo exploratório que nos permitiu identificar conceções, práticas e contextos no domínio da Formação Cívica. Selecionámos uma escola no distrito de Aveiro e entrevistámos 10 professores do 3.º CEB, coordenação e direção da escola, analisámos documentos oficiais e observámos aulas. Concluímos que a operacionalização da Formação Cívica está refém de um conjunto de condicionalismos, entre eles: a ausência de orientações curriculares; a sobreposição de funções do Diretor de Turma; o não reconhecimento das funções pedagógicas de uma área não disciplinar; a ausência de preparação científica e pedagógica dos professores responsáveis por este tempo letivo. A segunda fase do estudo contemplou a conceção, desenvolvimento, implementação e avaliação de um percurso formativo projetado com base nos resultados do estudo exploratório e da revisão da literatura realizada para o efeito. O percurso formativo, desenvolvido na modalidade de Oficina de Formação (OF), envolveu e alicerçou-se no potencial das tecnologias (participação numa comunidade online; criação de blogues; desenvolvimento de recursos digitais) e envolveu sete professores. Dos professores participantes na OF, foram analisados em detalhe o percurso formativo de três professoras de diferentes escolas do ensino básico e com diferentes níveis de experiência letiva em Formação Cívica. A realização deste percurso formativo permitiu-nos: i) identificar processos de reconstrução do conceito de cidadania e do lugar da Formação Cívica; ii) identificar uma visão mais alargada e transformadora da Formação Cívica ao invés de abordagens restritas de cariz administrativo; ii) analisar a importância da partilha de experiências, do feedback, do suporte e da reflexão no processo formativo para o desenvolvimento das práticas pedagógico-didáticas; iv) conceptualizar o conhecimento profissional docente associado à Formação Cívica. Consideramos que este estudo contribui para a necessária reflexão sobre o espaço e o papel da Educação para a Cidadania no sistema educativo Português, assim como para o debate da afirmação da Formação Cívica (com esta ou outra designação mas necessariamente com novos contornos), em particular no currículo do ensino básico. Sustentamos ainda a importância fundamental da formação contínua (de carácter ativo e reflexivo) e da construção partilhada do conhecimento para o desenvolvimento profissional dos professores de Formação Cívica, necessário para dar resposta aos desafios da Educação para a Cidadania.

Caracterização ecológica e serviços ambientais prestados por salinas tropicais

O presente trabalho aborda aspectos da Ecologia e serviços ambientais prestados pelas salinas solares tropicais. Estes importantes ecossistemas artificiais adquirem uma relevância ecológica, económica e cultural nestas zonas do globo por se manterem produtivos durante todo o ano. O estudo foi realizado em 02 salinas da região Nordeste do Brasil, no Estado do Rio Grande do Norte, produtor de 97% o sal marinho nacional. Nestas salinas, verificou-se que existe uma lacuna de conhecimento acerca do histórico de exploração no Brasil, assim como da sua caracterização ambiental. Foi ainda aplicada uma abordagem sistêmica integrando os serviços ecossistêmicos aplicados à conservação das salinas solares. Portanto, teve-se como objetivo central desta investigação realizar a caracterização das salinas solares no litoral semiárido do Brasil, analisando os serviços ambientais prestados por estes importantes ecossistemas, assim como as potencialidades alternativas para a sua gestão. Através de análises de parâmetros físico-químicos da salmoura e dos sedimentos foram caracterizados os diferentes tipos de habitats identificados ao longo do gradiente espacial da salinidade. Concomitantemente, também foram identificados os principais serviços ambientais prestados pelas salinas solares tropicais, os quais permitiram a realização de uma análise sobre quais desses serviços poderiam ser interrompidos em função das diferentes pressões antrópicas. A partir desta análise, verificou-se que as salinas são sistemas integrados, representando ecossistemas com dinâmicas biogeoquímicas diferenciadas, as quais estão associados ao manejo para a atividade econômica de produção de sal. Essa afirmativa é observada pois, de um lado tem-se o ecossistema hipersalino, composto por um mosaico de habitats, cuja salinidade é um dos principais agentes reguladores da biodiversidade encontrada em cada habitat. Por sua vez, é exatamente a logística da produção de sal marinho que determina o gradiente espacial da salinidade, o qual influencia na segmentação dos diferentes habitas encontrados nas salinas. Assim, percebe-se que quando corretamente manejado, um sistema biológico típico de uma salina é uma ferramenta de auxílio à produção de sal, configurando-se neste caso como o principal serviço ecossistêmico voltado exclusivamente ao importante mercado do Brasil: a produção de sal marinho por evaporação solar.

‘To me, it's like a little box of tricks’: Breaking the depressive interlock as a programme participant in mindfulness-based cognitive therapy

Objectives. Mindfulness meditation practices have become increasingly popular in clinical therapies, changing patterns of depressogenic thinking for individuals who experience consecutive episodes of depression. We were interested in finding out how Mindfulness Based Cognitive Therapy (MBCT) worked for programme participants by focussing on how meditative practices changed their relationships to their thoughts. Design. Data for the study came from six semi-structured research interviews carried out with individuals who had taken part in an 8 week MBCT programme Methods. We used Interpretative Phenomenological Analysis (IPA) to analyse the experiential accounts. Results. We report on two superordinate themes – Engaging the Neutral Mind (with subordinate themes ‘breaking the paralysis of worry’ and ‘choosing to think differently’) and Experiencing the Neutral Mind (with subordinate themes of ‘reflection on previous thinking styles’ and ‘becoming psychologically self-reliant’). Conclusions. Themes from the present study offer support to the assertion that mindfulness meditation helps facilitate a different mode of meta-cognitive processing with which to handle depression-related cognitions. Practitioner Points Participants reported that they experienced an enhanced capacity to differentiate between their thought processes, experiencing an ability to tolerate some more uncomfortable thoughts and experiencing a/more choice in how to respond to thoughts Participants recognised that ruminating over negative thoughts was related to depressive states and experienced a shift in meta-cognitive processes that actively challenged depressogenic cognitions Participants became more psychologically self-reliant and therapeutically independent following MBCT Integrating mindfulness based practices in therapy may be a mediating factor in sustaining psychological wellbeing and may help clients develop self-compassion Future research looks to examining exit cases to understand elements of MBCT which are experienced as less successful by clients

Microstructural and geochemical investigation of North American lower-middle Paleozoic trilobites and recent arthropods

Trilobites ¥tere collected from Ordovician and Devonian formations of Ontario} New York} Ohio} Oklahoma} and Indiana. Diversity was generally low} but 19..?telllS and Ph..~tY>ps ¥tere the most abundant species from the Ordovician and Devonian} respectively. Recent marine arthropods ¥tere collected from the Atlantic shore of the middle Florida Keys} and from the Pacific and lagoonal waters at Cape Beale} B. C. Fresh-water arthropods were collected along the shore of the Severn River in northcentral Ontario. Cuticles ¥tere analyzed for major} minor and trace elements, 180 and 13C isotopes, as ¥tell as examined by scanning electron micr?scope to identify original and diagenetic fabrics. Examination of trilobite cuticles by scanning electron microscope revealed several microstructures consistent with those observed in Recent arthropods. Microstructures} such as setae and tegumental gland duct openings} in like sized Lim/IllS and Isoteline trilobites may indicate common ancestral origins for these organisms, or simply parallel cuticle evolutions. The dendritic microstructure, originally' thought to be a diagenetic indicator, was found in Recent specimens and therefore its presence in trilobites may be suggestive of the delicate nature of diagenesis in trilobites. The absence of other primary microstructures in trilobites may indicate alteration, taxonomic control} or that there is some inherent feature of S EM examination which may' not allow detection of some features} while others are apparently visit·le onl~1 under SH.·1. The region of the cuticle sampled for examination is also a major influence in detecting pristine microstructures, as not all areas of trilobite and Recent arthropod cuticles will have microstructures identifiable in a SEM study. Subtleties in the process of alteration, however} ma~·· leave pristine microstructures in cuticles that are partial~/ silicified or do 10m itized, and degree and type of alteration may vary stratigraphically and longitudinally within a unit. The presence of fused matrices, angular calcite rhombs, and pyrite in the cuticle are thought to be indicative of altered cuticles, although pyritization may not affect the entire cuticle. t-~atural processes in Recent arthropods, such as molting, lead to variations in cuticle chemistries, and are thought to reflect the area of concentration of the elements during calcification. The level of sodium in Recent arthropods was found to be higher than that in trilobites, but highly mobile when sUbjected to the actions of VY'€'athering. Less saline water produced lovy'€'r magnesium and higher calcium values in Recent specimens .. and metal variations in pristine Ordovician trilobite cuticle appears to follow the constraints outlined for Recent arthropods, of regulation due to the chemislry of the surrounding medium. In diagenetic analysis, sodium, strontium and magnesium proved most beneficial in separating altered from least altered trilobites. Using this criterion, specimens from shale show the least amount of geochemical alteration, and have an original mineralogy of 1.7 - 2.4 mole % MgC03 (8000 t(> 9500 ppm magnesium) for both /s>..?/e/11S lJA'i.riff!11S and PseIAit'11J17ites I..itmirpin..itl/~ and 2.8 - 3.3 mole % MgC03 (5000 to 7000 ppm magnesium) for Ph.i{).?PS This is Slightly lower than the mineralogy of Recent marine arthropods (4.43 - 12.1 mole % MgC03), and slightly higher than that of fresh-water crayfish (0.96 - 1.82 mole % MgC03). Geochemically pristine trilobites were also found to possess primary microstructures. Stable isotope values and trends support the assertion that marine-meteoriclburial fluids were responsible for the alteration observed in a number of the trilobite specimens. The results of this stUdy suggest that fossil material has to be evaluated separately along taxonomic and lithological lines to arrive at sensible diagenetic and e nvironmenta I interpretations.

Heidegger's tragic Greeks : the relation between presence and deinon

Martin Heidegger's interpretation of the ancients was born out of something like a crisis in the interpretation of the Greeks, which can be characterized as nothing other than the realization of the idea that the Greek philosophers put a serious question mark over existence. This idea, which had its germination in Prussia with Jakob Burckhart and his teacher, but first came to be seriously cultivated in the Philosophy of Friedrich Nietzsche, was the first in depth investigation into whether the Greeks, on the one hand, questioned existence or, on the other hand, put a question mark over existence. To question existence is rather innocuous, since it amounts to little more, in the end, than a child looking up at the stars and asking what it all means. To put a question mark over existence, however, is another business entirely. For the Greeks, as the life work of Martin Heidegger amply demonstrates, the nature of Greek thinking and the objects towards which it is directed follows so absolutely from the tragic view of the human person that, in a certain sense, philosophy is Greek and could only have developed in Greece. Perhaps stating it a little less categorically, philosophy could have developed elsewhere at least to the extent that something like they way the Greeks understood life was at the forefront: presence, in other words. This thesis deals with the problem ofHeidegger's relation to the Greeks, specifically in terms of his understanding of the Greeks and presence. It is the position of this dissertation that the Greek notion of presence is, as Heidegger understands it, the homeliness of the hearth that radiates through all the things that humans concern themselves with. This is thought by Heidegger, as the Greeks did, specifically in contrast with the uncanninesslunhomeliness of the hqrnan apart from his or her concern with things. Therefore, the thesis is an attempt at exposing the relation between presence and the unhomely by situating it withing Greek existence and the meaning of the Greek Philosopher. In order to support this position, the thesis has been divided into five parts. The first two chapters deal with Heidegger's explanation of the relation between Greek notion of physics (Phusis), metaphysics (specifically in relation to an analysis of time and motion in Greek thought), and what Heidegger calls the fundamental attunement of Dasein (boredom). More exactly, it deals with these issues only so far as they allow us to bring out something like the notion of 'presence' in relation to things and homelessness or restlessness in relation to the human being. The rationale for these two chapters in relation to the central problem of the paper is that in Heidegger's elucidation of physics and metaphysics, he conducts his analysis in such a way that he explicitly uncovers that dimension of human existence that he calls the fundamental attunement of Dasein. This fundamental attunement is, in tum, similar to what the Greeks understood as the deinon, the uncanninesslunhomeliness of the human. The third and fourth chapters take as their explicit themes the problem of the Greek understanding of the assertion and the ways in which the person can comport himlherself toward things, two issues which are not separable. The rationale for these two chapters in relation to the central theme of the paper is that Heidegger's analysis of these two areas in Greek thought brings out precisely why the philosopher and the philosophical way of life is the highest mode of existence for the Greeks and how this is thought specifically in tenns of the uncanniness of humans. The final cijapter gives a complete elucidation of presence as the homeliness of the hearth and shows specifically how this is thought of in contradistinction to the uncanny/unhomely for the Greeks. 1I1 This last chapter also explains Martin Heidegger's reaction to the Greek's interpretation of the highest mode of existence, and what he posited as a counter-thought. The essay as a whole is an attempt to fully concertize an important dimension of Heidegger' s understanding of the Greeks, that is, the relation between presence and the deinon or Greek notion ofunhomely, which, to my la)owledge, has not been offered anywhere in commentaries on Heidegger.

Phe Ihesis examines the evolution of the -policies of the People fs Jtenublie of China towards J?hail°nd, PTal ysia, Singapore, Iidonesia pad the Philip-pines, organised in the Association of Southeast Asian Nations from 1969 to 1975• 2ze first central point of this study is an *ir sumption that the foreign relations of The People's Tepublic of Chi la Towards Southeast ^sia have been motivated by a dynamic interplay of t^o main factors: (1) Farxist-Leninist ideology and ICao J^e-tung Ph^ught, which dictate to China to behave as a revolutionary Dover vhich must assist the insurgent movements in the area in their strug fle to overthrow the local governments; (2) national interest, vhich demands of China to safeguard the southern flank of her territory bordering on Southerst 'sia through Friendly relations, trade and ot*»er conventional inrtniments of diplomacy. hile the tvo main motive factors are nuTually antagonistic and exclusivet the Chinere leaders are nevertheless at te mi ting to oring them iirco a coherent policy under Mao's theory of tve {hniity of op-nosites," vhich believes that it is -possible to reconcile these co-posing tendencies into a dynamic enuibrium through vhich both opnosites could be promoted at the same time although not to the same extent* la other words, the Chinese leaders conceive the dynamic equilibrium as a continuum between them in a mix in which one or the other orientation predominates in different •periods* Bins we might see China1 s conduct motivated in one period by mostly ideological considerations at the expense of the staire-to-state relations, then ve might see her policy in the middle of the continuum and suf ering from immo bill sine and just muddling through, or finally ?fe might see her emphasising friendly ties at the expense of support of revolutionary movements at the other extreme -point of the spectrum* !fhe mechanism vhich enables Peking to move from one pole to the other of the spectrum is activated by the following elementsJ (1) the result of an internal power struggle within the leadership in Peking between ideologically radical and moderate elements, which enables the victorious faction to initiate nev policies; (2) Peking's assessment of the changing intentions and capabilities of the major powers in the area; (3) internal changes within the countries of the area and the changing attitudes of their governments towards China; (4) changing fortunes of revolutionary movements operating in the area* 'Phe second major point of this study is an assertion that while China's conduct toward Southeast *lsia after her foundation in 1949 was primarily based upon ideological considerations, the beginning of the seventies saw the national interest reasserting itself as the leading motive factor* Thus China talks with her neighbours in Southeast asia in terms of relevance of fllong historical ties," casting herself into the role of a benevolent "older brother11 who is entitled to reopect and deference in exchange for patronage and protection* Hence the traditional echoes of the past are emerging ever stronger and influencing her postures towards the region, while the open support to revolutionary moevments is underplayed at the moment.
