Online Calibration Via Variable Length Computerized Adaptive Testing
Authors: Chang Yuan-chin Ivan , Lu Hung-Yi
Published: July 2009

Item calibration is an essential issue in modern item response theory based psychological or educational testing. Due to the popularity of computerized adaptive testing, methods to efficiently calibrate new items have become more important than that in the time when paper and pencil test administration is the norm. There are many calibration processes being proposed and discussed from both theoretical and practical perspectives. Among them, the online calibration may be one of the most cost effective processes. In this paper, under a variable length computerized adaptive testing scenario, we integrate the methods of adaptive design, sequential estimation, and measurement error models to solve online item calibration problems. The proposed sequential estimate of item parameters is shown to be strongly consistent and asymptotically normally distributed with a prechosen accuracy. Numerical results show that the proposed method is very promising in terms of both estimation accuracy and efficiency. The results of using calibrated items to estimate the latent trait levels are also reported.
Community-Acquired Methicillin-Resistant Staphylococcus Aureus in the Suburban Hand Surgery Patient Population

Published: July 2009

Methicillin-resistant Staphylococcus aureus (MRSA) is a frequent cause for patients to present to a physician's office or emergency department. We observed increasing numbers of community-acquired MRSA infections in patients admitted to the hand surgery service at our suburban academic center. It is an important issue as unsuspected community-acquired MRSA hand infections can be admitted to the hospital, inadequately treated, and allowed for nosocomial spread. This study was performed to examine the trend in the incidence of community-acquired MRSA infections in patients admitted to the hand surgery service in order to sensitize practitioners to have a high index of suspicion for this entity and promote early recognition and treatment of this organism. A multihospital retrospective chart review was undertaken to compare the total number of community-acquired MRSA infections in our hospital as well as the number in patients admitted to the hand surgery service with community-acquired MRSA from 2000 through 2008. Statistical analysis was provided by linear regression. Two community-acquired hand MRSA infections were treated in 2000, as compared to three in 2001 and 2002, four in 2003, five in 2004, six in 2005, 14 in 2006, 13 in 2007, and ten in 2008. This increase was statistically significant ( p=0.038). This retrospective review documents a rapidly rising number of community-acquired MRSA hand infections in the suburban environment. The hand surgeon must be aware of the increased prevalence of this entity to adequately combat this organism and prevent prolonged hospital stays, expanded morbidity, and inflated treatment costs.
Medical conditions in autism spectrum disorders
Authors: Bolton Patrick F.
Published: July 2009

Autism spectrum disorder (ASD) is a behaviourally defined syndrome where the etiology and pathophysiology is only partially understood. In a small proportion of children with the condition, a specific medical disorder is identified, but the causal significance in many instances is unclear. Currently, the medical conditions that are best established as probable causes of ASD include Fragile X syndrome, Tuberous Sclerosis and abnormalities of chromosome 15 involving the 15q11-13 region. Various other single gene mutations, genetic syndromes, chromosomal abnormalities and rare de novo copy number variants have been reported as being possibly implicated in etiology, as have several ante and post natal exposures and complications. However, in most instances the evidence base for an association with ASD is very limited and largely derives from case reports or findings from small, highly selected and uncontrolled case series. Not only therefore, is there uncertainty over whether the condition is associated, but the potential basis for the association is very poorly understood. In some cases the medical condition may be a consequence of autism or simply represent an associated feature deriving from an underlying shared etiology. Nevertheless, it is clear that in a growing proportion of individuals potentially causal medical conditions are being identified and clarification of their role in etio-pathogenesis is necessary. Indeed, investigations into the causal mechanisms underlying the association between conditions such as tuberous sclerosis, Fragile X and chromosome 15 abnormalities are beginning to cast light on the molecular and neurobiological pathways involved in the pathophysiology of ASD. It is evident therefore, that much can be learnt from the study of probably causal medical disorders as they represent simpler and more tractable model systems in which to investigate causal mechanisms. Recent advances in genetics, molecular and systems biology and neuroscience now mean that there are unparalleled opportunities to test causal hypotheses and gain fundamental insights into the nature of autism and its development.

Rhizochalin [(2R,3R,26R,27R)‐2,27‐diamino‐3‐hydroxy‐26‐[(2R,3R,4S,6R)‐3,4,5‐trihydroxy‐6‐(hydroxymethyl)tetrahydro‐2H‐pyran‐2‐yloxy]octacosan‐11‐one], an antimicrobial and cytotoxic marine two‐headed sphingolipid‐like natural product, isolated from the sponge Rhizochalina incrustata, and some related compounds were studied as anticarcinogenic and proapoptotic agents. The corresponding effects were tested on the mouse skin epidermal JB6 P+ Cl 41 cell line, its stable transfectants, THP‐1, HeLa, and SNU‐C4 human tumor cells using a variety of assessments, including cell viability (MTS), flow cytometry, anchorage‐independent soft agar, and luciferase assays. At 5–10 μM concentrations, rhizochalin was effective as an inhibitor of the malignant transformation of JB6 P+ Cl 41 cells or colony formation of human tumor cells, which exerted its action, at least in part, through the induction of p53‐dependent apoptosis. Structure–activity relationship study showed aglycon of rhizochalin to be the most active while peracetylated aglycon was the least active among the compounds studied.
Docosahexaenoic Acid Activates Some SREBP‐2 Targets Independent of Cholesterol and ER Stress in SW620 Colon Cancer Cells

Published: July 2009

The SREBP‐2 transcription factor is mainly activated by low cellular cholesterol levels. However, other factors may also cause SREBP‐2 activation. We have previously demonstrated activation of SREBP‐2 by the polyunsaturated fatty acid docosahexaenoic acid (DHA) in SW620 colon cancer cells. Despite activation of SREBP‐2, only a few target genes were induced and cholesterol biosynthesis was reduced. In the present study, gene expression analysis at early time points verified the previously observed SREBP‐2 target gene expression pattern. Activation of SREBP‐2 using siRNAs targeting Niemann Pick C1 protein (NPC1) led to increased expression of all SREBP target genes examined, indicating that activation of some SREBP‐2 target genes is inhibited during DHA‐treatment. Cholesterol supplementation during DHA treatment did not abolish SREBP‐2 activation. We also demonstrate that activation of SREBP‐2 is independent of ER stress and eIF2α phosphorylation, which we have previously observed in DHA‐treated cells. Thapsigargin‐induced ER stress repressed expression of SREBP‐2 target genes, but with a different pattern than observed in DHA‐treated cells. Moreover, oleic acid (OA) treatment, which does not induce ER stress in SW620 cells, led to activation of SREBP‐2 and induced a target gene expression pattern similar to that of DHA‐treated cells. These results indicate that DHA and OA may activate SREBP‐2 and inhibit activation of SREBP‐2 target genes through a mechanism independent of cholesterol level and ER stress.
Mirror foot: Treatment of three cases and review of the literature
Authors: Fukazawa Hodaka , Kawabata Hidehiko , Matsui Yoshito
Published: July 2009

Purpose

To describe three cases of mirror foot and to develop a new classification of the mirror feet with an emphasis on their treatment.

Methods

Surgical treatment was performed on three patients with mirror foot. Mirror feet in the English literature were surveyed and cases found in PubMed as well as our three cases were classified according to a new classification that was an analogy of the mirror hand classification proposed by Al-Qattan et al. (J Hand Surg Br 23:534–536, 1998).

Results

All three cases obtained satisfactory outcome after the treatment. In addition to these cases, 28 mirror feet were well described in the English literature, among which only seven cases have been documented for their treatment. All of the cases could be assigned to one of the categories of the proposed classification.

Conclusion

Mirror foot is a very rare congenital deformity of the foot. We successfully treated three novel cases of mirror feet. A classification of the mirror feet proposed in this article was useful in order to understand its nature and obtain a guideline for its treatment.

Published: July 2009

Human fibroblasts produce ceramide from sialyllactosylceramide on the plasma membranes. Sialidase Neu3 is known to be plasma membrane associated, while only indirect data suggest the plasma membrane association of β‐galactosidase and β‐glucosidase. To determine the presence of β‐galactosidase and β‐glucosidase on plasma membrane, cells were submitted to cell surface biotinylation. Biotinylated proteins were purified by affinity column and analyzed for enzymatic activities on artificial substrates. Both enzyme activities were found associated with the cell surface and were up‐regulated in Neu3 overexpressing cells. These enzymes were capable to act on both artificial and natural substrates without any addition of activator proteins or detergents and displayed a trans activity in living cells.
Human directed aggression in Brazilian domestic cats: Owner reported prevalence, contexts and risk factors
Authors: Ramos Daniela , Mills Daniel Simon
Published: July 2009

Aggression by cats towards humans is a serious behavioural, welfare and public health problem, although owners may believe it is an inevitable part of cat ownership. There has been little scientific investigation of the risk factors associated with this problem. One hundred and seven owners in the Sao Paulo region of Brazil, took part in a survey aimed at investigating the perceived prevalence of the problem, defining the most common contexts of human directed aggression and identifying associated potential risk factors. Human directed aggression occurred in 49.5% of cats and was most commonly associated with situations involving petting and play, followed by protection of a resource, when startled, when observing an unfamiliar animal and least commonly when unfamiliar people were present. Pedigree status, neuter status, a history of early trauma, sensitivity to being stroked, the absence of other cats in the home, relationship with other animals, level of background activity at home, access to the outside and tendency to be alone (meaning tendency to staying far from the family members) were all associated with an increased risk in one or more context. However, sex, age, age when acquired, source of pet, attachment to a specific household member, type of domestic accommodation, relationship with another cat if present and contact with other animals did not appear to increase the risk. The results suggest sensitivity to being stroked and background levels of stress in the home are the most pervasive risk factors, and future research should aim to investigate these factors further. These data are of relevance when advising owners about the risk and development of this problem.
Feline herpesvirus 1 and feline calicivirus infections in a heterogeneous cat population of a rescue shelter
Authors: Zicola Angélique , Saegerman Claude , Quatpers Dominique , Viandier Julie , Thiry Etienne
Published: July 2009

Feline herpesvirus 1 (FeHV-1) and feline calicivirus (FCV), associated with upper respiratory tract disease, are highly prevalent in cats worldwide. With the aim to investigate the importance of feline respiratory viruses in a heterogeneous population of cats, samples were taken in a rescue shelter in Liège, Belgium, between March 2005 and August 2006. Reverse transcription polymerase chain reaction (RT-PCR) and polymerase chain reaction (PCR) were performed to diagnose FCV and FeHV-1 infection in the sampled cats. The prevalence rate (33.1%) was higher for FCV than for FeHV-1 (20.1%) whereas prevalence rate of co-infection with both viruses was 10%. Gingivitis was more common in FCV infections (odds ratio (OR)=2.83) whereas respiratory signs were more often observed with FeHV-1 infections. The average age was significantly higher in FCV positive cats (38 months) than in FeHV-1 positive cats (29.9 months). The second and the fourth quarters of the year and the two first quarters were significantly more at risk than the others in the case of FeHV-1 and FCV infection, respectively. Age was found to be a confounding factor. High prevalence of both infections strengthens the importance of applying hygienic and preventive measures in rescue shelters where cats with an unknown status of vaccination are introduced.
DIAGRAMS OF AN ABELIAN GROUP
Authors: FATICONI THEODORE G.
Published: July 2009

In this paper, we characterize quadratic number fields possessing unique factorization in terms of the power cancellation property of torsion-free rank-two abelian groups, in terms of Σ-unique decomposition, in terms of a pair of point set topological properties of Eilenberg–Mac Lane spaces, and in terms of the sequence of rational primes. We give a complete set of topological invariants of abelian groups, we characterize those abelian groups that have the power cancellation property in the category of abelian groups, and we characterize those abelian groups that have Σ-unique decomposition. Our methods can be used to characterize any direct sum decomposition property of an abelian group.

Sudden deafness in a patient with secondary syphilis
Authors: Ibrahim F W , Malu M K
Published: July 2009

Objectives:

To emphasise the importance of considering a diagnosis of early acquired syphilis in all sexually active adults, and to review the ENT manifestations and treatment of acquired syphilis.

Case report:

A 24-year-old woman presented with sudden hearing loss, and subsequently developed clinical features suggestive of secondary syphilis. She was seen in the departments of ENT, dermatology, rheumatology and infectious diseases before a correct diagnosis was made. Treatment resulted in only partial recovery of hearing.

Conclusions:

With the exponential rise in syphilis cases in the UK, there has been a re-emergence of presenting manifestations that had previously become rare. Early syphilis should be considered in all sexually active adults who present with deafness, as prompt diagnosis and treatment are crucial for maximum recovery.
Mobile, one stage, bilateral ear surgery for chronic otitis media patients in remote areas
Authors: Homøe P , Sørensen H C Florian , Tos M
Published: July 2009

Objectives:

We evaluated the results of mobile, one stage, bilateral ear surgery conducted in Greenland, where chronic otitis media with and without suppuration is prevalent. The study aimed to increase the number of operations conducted and to reduce the cost of ear surgery in remote areas.

Materials and methods:

The study was longitudinal and prospective, with a two-year follow up. Seventeen East Greenlandic patients with bilateral chronic suppurative otitis media or chronic otitis media were selected. Their median age was 16 years; 53 per cent were female and 47 per cent male. Hearing was assessed using median air conduction pure tone average gain, and the ‘take rate’ (i.e. the percentage of total ears with a closed perforation) was evaluated.

Results:

All patients attended for follow up. Eighty-two per cent had at least one perforation closed, and the overall take rate was 65 per cent of the 34 ears. The median air conduction pure tone average gain after two years was 18 dB and 13 dB for the right and left ears, respectively. Fourteen patients (82 per cent) obtained an air conduction pure tone average hearing level of ≤25 dB in at least one ear. In total, 71 per cent of the patients were satisfied. There were no hearing hazards.

Conclusions:

The results of mobile, one stage, bilateral ear surgery conducted in Greenland for long-lasting chronic suppurative otitis media and chronic otitis media were acceptable and safe, and more ears underwent surgery at reduced cost compared with unilateral ear surgery.
Ossicular chain reconstruction with a titanium prosthesis
Authors: Roth J A , Pandit S R , Soma M , Kertesz T R
Published: July 2009

Objective:

Ossicular chain damage from chronic ear disease is a significant problem in the Australian population. The ideal ossicular chain reconstruction prosthesis has yet to be defined. This paper examines, for the first time, the use of a titanium prosthesis for ossicular chain reconstruction in Australian patients.

Study design:

Retrospective chart review.

Subjects and methods:

All patients undergoing ossicular chain reconstruction with a titanium prosthesis between 1 February 2002 and 31 March 2007.

Results:

Results showed a low complication rate, with only one extrusion out of 55 cases (1.8 per cent). Successful rehabilitation of conductive hearing loss (i.e. to ≤20 dB air–bone gap) was obtained in 85 per cent of the partial ossicular chain reconstruction group and 77 per cent of the total ossicular chain reconstruction group. Pure tone thresholds improved by an average 18 dB in the partial reconstruction group and 25 dB in the total reconstruction group.

Conclusion:

Titanium is an ideal material for ossicular chain reconstruction due to its ease of insertion, low rate of extrusion and good functional results.
The construction of multiple identities in elderly narrators' stories
Authors: NORRICK NEAL R.
Published: July 2009

Elderly storytellers are often at pains to represent multiple past identities even within the scope of a single account. Some of these identities may be incompatible, as when the teenage hell-raiser straightens out to become the perfect home-maker, and then after her husband dies becomes a successful business woman. Retrospective reassessment follows from long and varied experience, and hence becomes a natural resource for storytellers old enough to have had the time to re-evaluate events. Further, comments about people and places from the past automatically force a shift between the telling frame and the narrative frame; they create the impression that the teller's present identity is not representative of all aspects of the narrator's projected identity. In addition, elderly narrators insert others' perspectives into their stories, as when a widow explicitly introduces the perspective of her deceased husband into a story in progress. Elderly tellers convey multiple identities beyond what they project, and their listeners form opinions of them based both on what they reveal about their pasts and how they reflect on them from their current perspectives, and this also results in the construction of multiple and on occasion conflicting identities. This article reports an analysis of such discourse practices in stories told about themselves by people aged 80 or more years living in Indiana.
Writing about age, birthdays and the passage of time
Authors: BYTHEWAY BILL
Published: July 2009

How do we experience ageing, how do we interpret changes in our lives and what do we say about the passage of time? The aim of this paper is to present longitudinal evidence about the personal and social significance of birthdays in adult life and, in particular, how birthdays contribute to a sense of ageing. The primary source of data is the Mass-Observation Archive at the University of Sussex. Members of its panel of ‘ordinary’ people living in the United Kingdom were in 1990 invited to write anonymously about celebrations, and in 2002 they were invited to write more specifically on the topic of birthdays. A total of 120 accepted both invitations and 55 included accounts of their last birthday in both submissions. As a consequence, it is possible to compare what they wrote on the two occasions and how this reflects their unfolding experience and changing feelings about age. The analysis reveals the personal salience of the date of a birthday and of continuity in how birthdays are celebrated. Who remembers birthdays and who participates in their celebration reflect the generational structure of families and age-related patterns of friendship. Birthdays are used to celebrate collective continuity more than individual change.
Time, the body and the reversibility of ageing: commodifying the decade
Authors: COUPLAND JUSTINE
Published: July 2009

Contemporary popular culture proposes new ideological associations between time, ageing, the body and personal identity projects. In a range of magazine texts, television shows and associated websites, several commercialised discourses equate ageing, and women's ageing in particular, with the ‘look’ of ageing. They project a version of personal ageing that is reversible and repairable, on the presumption that looking younger is universally a desirable goal and one that can be reached through regimes of control operating on skin, body shape and weight, hair and clothing. Different moral stances are established in these discourses. One set offers magazine readers putative control over acknowledged risks and threats deemed inherent to ageing. Such texts invoke personal responsibility for maintaining and indeed for re-claiming a youthful appearance in middle and old age. Another set shames and vilifies people who ‘look older than they should’. In those cases, visible ageing needs to be urgently dealt with, on the gerontophobic assumption that the look of ageing renders the individual progressively less socially desirable or even less acceptable. Different frames of mediation, such as the keying of personal censure and humiliation as play, complicate the moral critique of these discourses, even though their ageist orientations are often stark. The decade is constructed as an important unit of bodily ageing, when the target is to look or in some ways to be ‘ten years younger’.
Discourse, identity and change in mid-to-late life: interdisciplinary perspectives on language and ageing
Authors: COUPLAND JUSTINE
Published: July 2009

The papers in this special issue contribute to the growing body of research on sociolinguistic and discursive interpretations of mid and later life by investigating some of the identity affordances and constraints associated with ‘being middle-aged’ or ‘being old’. The papers here offer qualitative, contextually based analyses of a broad range of data and use various methodological and theoretical perspectives: narrative theory, critical pragmatics, social theory and discursive psychology. The main focus is on the ways in whichchangeimpacts on the ageing individual, and how this change is discursively interpreted and negotiated bothbyandfororaboutindividuals in diverse social frames. We examine age and change as they interact with personal and social identity in personal diary accounts, in print, on the television and web media, in conversations amongst friends and acquaintances, in interviews and during storytelling. Language and communication are examined as resources for making and interpreting the meanings of ageing, at both the macro (societal) and micro (individual and inter-personal) levels.
Dealing with life changes: humour in painful self-disclosures by elderly Japanese women
Authors: MATSUMOTO YOSHIKO
Published: July 2009

This paper examines the ways in which older people depict verbally the life changes that accompany old age. It reports a study of Japanese elderly women's casual conversations with their friends, during which they talked about their husbands' deaths and illnesses. A frequently observed discourse practice among old people is ‘painful self-disclosure’ (PSD), in which unhappy personal information on one's ill health, immobility or bereavement is revealed and speakers describe themselves using negative stereotypes of old age. During the observed conversations, however, the PSD accounts were frequently accompanied by humour and laughter. This paper examines the complex structure of the PSDs. To exemplify, a simple statement of death and illness given early in a conversation is later elaborated with descriptions of unremarkable domestic events, e.g. complaints about the husband's behaviour. Through shifting the frame of the narrative to quotidian normality, the elderly speakers convert painful life events to everyday matters that they can laugh about. Furthermore, it was found that the humour is sustained through interactions during which the hearers often laughed with the speaker. The study suggests that the disclosure of age-related negative experiences is not necessarily uniformly gloomy, but rather is combined with expressions of personal and social identities and nuanced and modulated through a complex resolution of the speaker's intentions and social expectations.
Doing change and continuity: age identity and the micro–macro divide
Authors: NIKANDER PIRJO
Published: July 2009

This paper is a study of the discursive management of notions of change and continuity in interview talk. It presents selected short empirical examples from interviews with 22 Finnish baby-boomers, and discusses the methodological and theoretical issues that arise. Following a review of the major approaches to the study of age identity, the analytic intersection between qualitative gerontology and discursive psychology is explored. The analysis identifies how the frequent use of a ‘provisional continuity device’ enables speakers simultaneously both to acknowledge and to distance themselves from factual notions of physical or psychological lifespan change. The key methodological argument is that the discursive analysis of age-in-interaction cannot necessarily be achieved through the myopic micro-study of discursive strategies, but rather two suggestions are made. First, it is argued that analytically-anchored and rigorous discursive gerontology that both systematically draws on and contributes to the broad field of discursive research provides a means by which to test empirically post-modern conceptualisations of age identity. Second, it is suggested that analyses of age-talk in everyday and institutional settings provide an analytical and theoretical middle-ground between the macroversusmicro or ‘microfication’ debate in gerontology.
Egalitarian challenges to global egalitarianism: a critique
Authors: BARRY CHRISTIAN , VALENTINI LAURA
Published: July 2009

Many political theorists defend the view that egalitarian justice should extend from the domestic to the global arena. Despite its intuitive appeal, this ‘global egalitarianism’ has come under attack from different quarters. In this article, we focus on one particular set of challenges to this view: those advanced by domestic egalitarians. We consider seven types of challenges, each pointing to a specific disanalogy between domestic and global arenas which is said to justify the restriction of egalitarian justice to the former, and argue that none of them – both individually and jointly – offers a conclusive refutation of global egalitarianism.
International justice and the reform of global governance: a reconsideration of Michael Walzer's international political theory
Authors: SUTCH PETER
Published: July 2009

Walzer has recently updated his just war theory to take account of terrorism, humanitarian military intervention and new interpretations of the doctrine of self-defence, pre-emptive and preventative warfare The ethical considerations that underwrite Walzer's most recent work invite us beyond the routine citation of his work to a proper consideration of the moral parameters of international politics. Beyond Just and Unjust Wars Walzer has a wealth of insight into the key questions of international theory. His work on toleration, the nature of universality or on the role of social criticism has always been the basis of his insight in to the hard questions of international ethics. Despite being heavily criticised for being communitarian or conservative (both charges that need serious re-evaluation) Walzer's ideas offer a real alternative to the dominant neo-Kantian cosmopolitan tradition and a workable ethical framework for thinking about the challenges of contemporary international politics and international law. Nowhere is this more apparent than in the final essay of Arguing About War. The essay, entitled ‘Governing the Globe’ offers a radical vision of a reformed international society inspired by the principles that underpin Walzer's development of his just war theory and it is vital that we take notice.
A haunted past: requesting forgiveness for wrongdoing in International Relations
Authors: LÖWENHEIM NAVA
Published: July 2009

This article examines why states ask for forgiveness from other states or peoples that they have harmed. Asking for forgiveness has significant political, legal, and moral implications. But beyond these, the subject concerns how states confront their history and their collective responsibility for wrongdoing. My focus on the reasons states have for asking forgiveness could also improve our understanding of conflict resolution. The article introduces an innovative typology of requests for forgiveness by presenting important conceptual distinctions in the terminology currently employed in the field. Apologies, regrets, and expressions of sorrow are conceptualised as distinct avenues of asking forgiveness with varying degrees of significance and meaningfulness. I assert that the type of request for forgiveness is influenced by the degree of severity attributed to a wrongdoing and by the extent to which a state perceives its image as threatened by its wrongful act. The article analyses the important 1951 statement of West Germany's Chancellor Adenauer regarding the Jewish Holocaust as an example of a type of request for forgiveness.
A post-liberal peace: Eirenism and the everyday
Authors: RICHMOND OLIVER P.
Published: July 2009

The ‘liberal peace’ is undergoing a crisis of legitimacy at the level of the everyday in post-conflict environments. In many such environments; different groups often locally constituted perceive it to be ethically bankrupt, subject to double standards, coercive and conditional, acultural, unconcerned with social welfare, and unfeeling and insensitive towards its subjects. It is tied to Western and liberal conceptions of the state, to institutions, and not to the local. Its post-Cold War moral capital, based upon its more emancipatory rather than conservative claims, has been squandered as a result, and its basic goal of a liberal social contract undermined. Certainly, since 9/11, attention has been diverted into other areas and many, perhaps promising peace processes have regressed. This has diverted attention away from a search for refinements, alternatives, for hybrid forms of peace, or for empathetic strategies through which the liberal blueprint for peace might coexist with alternatives. Yet from these strategies a post-liberal peace might emerge via critical research agendas for peacebuilding and for policymaking, termed here, eirenist. This opens up a discussion of an everyday ‘post-liberal peace’ and critical policies for peacebuilding.
Reclaiming the Utopian imaginary in IR theory
Authors: BRINCAT SHANNON
Published: July 2009

This article aims to reinvigorate the utopian imagination as a vital and necessary component in IR theory. Since the First Great Debate between the Realists and the Utopianists (or more accurately, the Liberal-Internationalists) the utopian tradition has been viewed as being both subjective and arbitrary, leading to its dismissal as vain idealism in world politics. This article re-interrogates the arguments of Carr and Morgenthau and finds that they have relevance today only as against closed systems of utopia and have little bearing against the open-dialectical utopianism which is advocated here as a viable alternative to the sterility of realism. The article also examines the historical nexus between realism's dismissal of utopianism and the wider movements in political philosophy via a critical engagement with the works of Popper, Berlin and Arendt. Finally, after exploring the limitations of Booth's idea of ‘Utopian Realism’, the article argues that utopianism should no longer be assumed to be a blueprint for a future, perfect society, a tradition fraught with the danger of proto-totalisation, but as a critical imaginary that acts as a heuristic device to reveal the fissures in existing reality and as an ideational motivating force for progressive change in world politics.
Feminist fatigue(s): reflections on feminism and familiar fables of militarisation
Authors: STERN MARIA , ZALEWSKI MARYSIA
Published: July 2009

In this article we critically consider the idea that feminism has performatively failed within the discipline of International Relations. One aspect of this failure relates to the production of sexgender through feminism which we suggest is partly responsible for a weariness inflecting feminist scholarship, in particular as a critical theoretical resource. We reflect on this weariness in the context of the study and practice of international politics – arenas still reaping the potent benefits of the virile political energies reverberating since 9/11. To illustrate our arguments we re-count a familiar feminist fable of militarisation – a story which we use to exemplify how the production of feminist IR is ‘set’ up to ‘fail’. In so doing we clarify our depiction of feminism as seemingly haunted by its inherent paradoxes as well as explaining why it matters to discuss feminism within the locale of the academic study of international politics. We conclude with a consideration of the grammar of temporality that delimits representations of feminism and move to recast feminist failure as aporetic and concomitantly implicated in the process of intervening politically.
The laws of war and the state of the American exception
Authors: RALPH JASON
Published: July 2009

This article examines the US response to the 9/11 terrorist attacks using Carl Schmitt's concept of the exception. It argues that the Bush administration's response is consistent with Schmitt's view, which argued that US policy continued the historical practice of drawing lines that separated ‘civilisation’ from zones of exception where the normal laws governing warfare did not apply. This suggests that the state of exception declared after 9/11 is not contingent on the rise and fall of the terrorist threat, rather it is the latest manifestation of ‘global linear thinking’ and therefore a permanent feature of American hegemony. However, the article does not accept this pessimistic conclusion. US policy since 9/11 fits squarely with a Schmittian explanation only because conservative nationalists have used the war on terror to help reconstruct a sense of American ‘exceptionalism’. An alternative reading of how American liberalism should respond to terrorism can be found in the manner in which the Bush administration's policy was rejected by the US Supreme Court.
Related powers of the United Nations: reconsidering conflict management of international organisations in Ontological light
Authors: PIIPARINEN TOUKO
Published: July 2009

The mainstream literature on the UN has been underlain by a methodological individualist philosophy, according to which all social phenomena, and particularly the functioning of all social institutions, should always be seen as resulting from the decisions of individual actors, as if the whole (organisation) was never more than the sum of its parts (members of an organisation). Such a fallacy has been denounced by social constructivist approaches which account for the existence of certain emergent properties of the UN, such as collective identity, which cannot be reduced to its constituent units, namely, states. These accounts, however, have offered a partial picture of the holistic understanding of the UN, as they have failed to comprehend, or perhaps simply ignored the causal powers of such emergent properties. This article enhances constructivist approaches by dint of the critical realist models of Synchronic Emergent Powers Materialism and Transformational Model of Social Activity. The value added of these two models in comprehending the powers associated with the UN Security Council lies in their ability to function as instructive metaphors; they allow for the independent and irreducible existence of certain mechanisms by which the Council controls international conflicts but nevertheless recognises that these can only emerge from the mutual interaction between agents (states) and structure (UN institutions).

One of the insights of Constructivism is that our world is, in part, made by what we say about it. We make things what they are by saying what they are. One way is through the use of metaphor; by asserting that one thing is another thing. Does our saying that a state is a person make it a person?

A way to intervene in this discussion is by addressing it not in the abstract, but guided by a cognate question: Can states commit crimes, a uniquely human act? If states can commit and be liable for crimes, they must be able to form intents. If they are indeed persons in the relevant sense, this is no problem; if their personality is trope, however, attribution of criminal responsibility becomes tenuous.

To analyse the issue, I trace the development of the trope of speaking of a group as if it were an individual from Roman Law, through to Hobbes, corporate law and IR Theory. Much hinges on Hobbes' elision of ‘body’ and ‘person’. I conclude that it is too much to expect of a metaphor that it act, that it have reasons, beliefs, and desires, and that these sum to intentions.

Unknotting sequences for torus knots
Authors: BAADER SEBASTIAN
Published: July 2009

The unknotting number of a knot is bounded from below by its slice genus. It is a well-known fact that the genera and unknotting numbers of torus knots coincide. In this paper we characterize quasipositive knots for which the genus bound is sharp: the slice genus of a quasipositive knot equals its unknotting number, if and only if the given knot appears in an unknotting sequence of a torus knot.
Were Cities Built as Images?

Many ancient city sites display a remarkable regularity in their plan which has led to considerable debate on the symbolism and intentionality which may lie behind these arrangements. Grid plan cities of the Greek and Roman world were discussed by Haverfield almost a century ago, but it was above all the cities of South and East Asia analyzed by Wheatley in his influential Pivot of the Four Quarters (1971) which has given new emphasis to the potential of meaning and significance. Such planned cities necessarily incorporate an essential tension between praxis — the practical day-to-day needs of the urban community — and idealism, the desire to impose on those practical concerns a city-plan which expresses a symbolic or cosmological image. Contemporary texts, where they exist, may help towards an answer, but the physicality of the city plan itself provides the crucial ground for argument as to whether symbolic or ideological imperatives governed the actual outcome. Cities may be conceptualized in ideal terms without ever taking on the physical attributes of any ideal form. The contributors to this Viewpoint approach the issue from a diversity of standpoints and with reference to different geographical areas. Were cities built as images? Did powerful belief systems combined with strong centralized control give rise to cities where the moat represented the encircling sea and the raised cathedral the mountain-dwelling of the gods? Or are such readings more the product of Western analysis and wishful thinking than the original intentions of their builders? The discussion here is opened by an architectural historian, who places city-planning firmly within the Western intellectual tradition, and considers it in particular as a product of Greek geometry. A series of regional specialists then take up the baton and assess the evidence for symbolic city planning in Egypt, the Roman world, South and Southeast Asia, and Mesoamerica. How far did cities of the Classical world conform to ideas set out by Aristotle and Vitruvius? Were the regulations of the Artashastra really adopted as a practical guide for city lay-out in South Asia? The balance of evidence — of what may have been intended, against what was actually laid out on the ground — provides fertile ground for a stimulating diversity of opinions.
Introduction

The question today is the same as that of twenty years ago: what do we call the events that transformed eastern Europe in 1989? Our improved perspective has not necessarily generated better answers. The most popular term is ‘revolution’, but many observers still hesitate to apply it to largely non-violent change. Can there be a ‘liberal revolution’? Timothy Garton-Ash's evocative neologism ‘refolution’ (meaning ‘revolution’ and ‘reform’) captures well the ambivalence many feel about describing a gradual transition to democracy as ‘revolutionary’. The processes of civil society formation he observed in the 1980s by no means concluded with 1989; in south-eastern Europe in particular the transition to democracy has not been revolutionary but slow and painful. Perhaps ‘democracy’ is not even the right word.
What Have We Learned since 1989?
Authors: MAIER CHARLES S.
Published: July 2009

This paper is a frankly subjective effort to return to questions posed about the nature of communist rule and the sudden collapse of communism in the light of the intervening two decades. It asks, first, why feelings of elation about the transformations of 1989 faded relatively quickly, second, why the communist system collapsed so clamorously, and, third, how might we best describe its earlier operation. The paper suggests that there will always be a sense of let-down after intensely hopeful political activity. It endeavours to provide a model of social complexity that communist rule with its Marxist archetypes of social development could not really master. But it also rejects the idea that ‘society’ under communism can be judged autonomously apart from the regime that sustained and structured it. Efforts to do so will trivialise the degrees of repression and surveillance. Finally the paper proposes that the nature of communist rule in the decades after Stalin must be described in terms of a ‘life cycle’ metaphor, such as the idea of ‘late style’ provides for artistic creation. It is fruitless to describe an ideal type of transformative political regime that makes no allowance for change over time. Hence, returning to the first enquiry, the paper argues that efforts to reclaim communal fulfilment will always exist or revive alongside efforts at individual emancipation.
The Revolutions of 1989: Causes, Meanings, Consequences
Authors: TISMANEANU VLADIMIR

The events of 1989 had world-shattering revolutionary consequences. They brought about a new vision of the political based upon a rediscovery of democratic participation and civic activism. The upheaval in the east, and primarily in the central, European countries, represented a series of political revolutions that led to the decisive and irreversible transformation of the existing order. When explaining 1989, one needs to focus on three major themes: the deep-seated meanings of the collapse of state socialist regimes in east central Europe, the nature of revolutions at the end of the twentieth century, and the role of critical (public) intellectuals in politics. There is no single factor that explains the collapse of Leninism: economics as much as politics, and culture as much as insoluble social tensions converged in making these regimes irretrievably obsolete. The aftermath of 1989 generated a fluidity of political commitments, allegiances and affiliations that signalled a general crisis of values and authority. There is a need for ‘social glue’ and the existing political formations have failed to imagine such ingredients for the consensus needed in order to generate constitutional patriotism. A fundamental source for reinforcing democracy in east central Europe is the synthesis between the history and the memory of communism with the purpose of achieving moral justice.
1989 as a Lens for the Communist Past and Post-communist Future
Authors: KOPSTEIN JEFFREY
Published: July 2009

Political scientists have documented significant variation in political and economic outcomes of the 1989–91 revolutions. Countries bordering on western Europe have become relatively democratic and economically successful, with both democracy and wealth dropping off as one moves east and south. Explanations for this variation and the replication of an older pattern on the Eurasian landmass have moved farther and farther into the past. Yet in moving to thelongue durée, more proximate events such as the revolutions of 1989, the demise of communism and even the communist experience itself recede into the background and are themselves accounted for by antecedent conditions. The article discusses how two more proximate factors helped to change older patterns in central and eastern Europe: the impact of communist modernisation and the prospect of European integration.
