Inscribing the Other, Inscribing the Self: Hindu-Muslim Identities in Pre-Colonial India
Authors: Talbot Cynthia
Published: June 2009

The nature of medieval Hindu-Muslim relations is an issue of great relevance in contemporary India. Prior to the 200 years of colonial subjection to the British that ended in 1947, large portions of the Indian subcontinent were under Muslim political control. An upsurge of Hindu nationalism over the past decade has led to demands that the state rectify past wrongs on behalf of India's majority religion.' In the nationalist view, Hindu beliefs were continually suppressed and its institutions repeatedly violated during the many centuries of Muslim rule from 1200 C.E. onward. The focal point of nationalist sentiment is the most visible symbol of Hinduism, its temples. As many as 60,000 Hindu temples are said to have been torn down by Muslim rulers, and mosques built on 3,000 of those temples' foundations. The most famous of these alleged former temple sites is at Ayodhya in North India, long considered the birthplace of the Hindu god Rama. The movement to liberate this sacred spot, supposedly defiled in the sixteenth century when the Babri Masjid mosque was erected on the ruins of a Rama temple, was one of the hottest political issues of the late 1980s and early 1990s. Tensions reached a peak in December 1992, when Hindu militants succeeded in demolishing the mosque.
Race-Class-Gender Ideology in Guatemala: Modern and Anti-Modern Forms
Authors: Smith Carol A.
Published: June 2009

More often than not, women bear the burden of displaying the identifying symbols of their ethnic identity to the outside world, whether these be items of dress, aspects of language, or distinctive behavior. Men of the same ethnic group, especially when filling lower-order positions in the local division of labor, usually appear indistinguishable from men of a different ethnicity but in similar class positions. Thus in Guatemala, for example, one readily identifies a Maya Indian woman by her distinctive and colorful dress, her tendency to speak only the local dialect of a Maya language, and her modest demeanor when in public settings, especially those involving non-Maya. Most Maya men, in contrast, are not so easily distinguished from non-Maya (that is, Ladino) men of equivalent class in Guatemala.
Entrepreneurs and Democratization: Iran and the Philippines
Authors: Parsa Misagh
Published: June 2009

The relationship between social structure and the emergence of democracy has long intrigued social scientists. In an early statement of the modernization perspective on this topic, Lipset (1960) postulated that a strong association exists between the degree of socioeconomic development and democracy. As economic development rose, so did wealth, income, and education, but income inequality declined, resulting in a population of moderate upper and lower classes and an expanding middle class, all of which favored the development of democratic political institutions. Subsequent quantitative studies found that a strong correlation can indeed be demonstrated between socioeconomic development and democratic institutions (Bollen 1983; Bollen and Jackman 1985). Despite significant contributions, these studies have not paid sufficient attention to either social agency or the mechanism of democratization during transitional periods. This essay will examine both of these factors by focusing on the role played by entrepreneurs in ousting dictatorial regimes.
Making Sense of Modernity: Changing Attitudes toward the Immigrant and the Gaucho in Turn-of-the-Century Argentina
Authors: Delaney Jeane
Published: June 2009

The experience of modernity is one that cuts across national boundaries. Regardless of where it occurs, modernization—defined here as the nexus of changes that includes technological innovation, economic rationalization, demographic change, the bureaucratization of the state, and the triumph of science—has certain inevitable consequences. To live in a modern society means to live in a constantly changing world, in which the forces of modernity have dissolved old forms of community, altered traditional notions of work, undermined social hierarchies, produced new social spaces, and transformed the sights, sounds, and even smells of everyday life. Modernization also engenders its own response. Societies in the throes of rapid modernization inevitably have their critics: individuals who for a variety of reasons object to the myriad of changes that accompany this process. Recoiling from the present, these antimodernists take refuge in an often idealized past, longing for what they believe to be a simpler, purer way of life.
Fruit Trees and Family Trees in an Anthropogenic Forest: Ethics of Access, Property Zones, and Environmental Change in Indonesia
Authors: Peluso Nancy Lee
Published: June 2009

Landscapes are culture before they are nature; constructs of the imagination projected onto wood and water and rock. … But once a certain idea of landscape, a myth, a vision, establishes itself in an actual place, it has a peculiar way of muddling categories, of making metaphors more real than their referents; of becoming, in fact, part of the scenery (Simon Schama 1995:61).

Nature is seen by humans through a screen of beliefs, knowledge, and purposes, and it is in terms of their images of nature, rather than of the actual structure of nature, that they act. Yet, it is upon nature itself that they do act, and it is nature itself that acts upon them, nurturing or destroying them.

Expanding the Split Labor Market Theory: Between and Within Sectors of the Split Labor Market of Mandatory Palestine
Authors: Bernstein Deborah S.
Published: June 2009

Palestine, under British mandatory rule since the end of the First World War, was an arena of confrontation between Arabs and Jews over land, immigration, and political power, as well as over place and position in the labor market. This article will deal with the split labor market of mandatoryPalestineand the actors within it. The analysis will make use of the split labormarket theory of Edna Bonacich. In her theory she posits a situation in whichtwo groups of labor, belonging to different ethnic and national origins, meet in the same labor market. The more advantageous ethnic group has been able, due to its past history and its more advantageous position within world capitalist development, to ensure a higher value for its labor but considers itself threatened by the presence of the less advantageous groups, whose labor has lower value and thus greater attraction to employers who aim to maximize their profits. The theory then goes on to develop the different ways in which cheaper labor might serve to displace and substitute higher-priced labor and the strategies pursued by the latter in recurring attempts to maintain its relative advantage.
The Consequences of the Military Revolution in Muscovy: A Comparative Perspective
Authors: Poe Marshall
Published: June 2009

What has been called the early modern military revolution may be described most simply as the replacement of small cavalry forces by huge gunpowder infantry armies. The revolution was a diffusionary process with a relatively well-understood chronology and geography. The innovations at its core began in northern Italy in the later fifteenth century and spread throughout central, northern, and eastern Europe in the three centuries that followed. Seen in this way, it was a unique and unitary phenomenon. Thus we speak ofthemilitary revolution, an episode in world history, instead of several different revolutions in the constituent parts of Europe. Nonetheless, the course and impact of the revolution were different in the regions it eventually affected.
Global Violence and Nationalizing Wars in Eurasia and America: The Geopolitics of War in the Mid-Nineteenth Century
Authors: Geyer Michael
Published: June 2009

The histories of Germany and the United States became deeply entangled in the century of total war. After (re)unification on the battlefield in the midnineteenth century, both countries underwent rapid transformations through national programs of industrialization based on new products and technologies and emerged as great powers with global pretensions at the beginning of the twentieth century. An initial, and somewhat hesitant, confrontation in World War I was followed by a period of oscillation and confusion during the 1920s and 1930s, as leading elements in the two economies sought grounds for collaboration even as the political development of the two nations diverged, one moving toward fascism, the other toward a liberal democratic renewal. This produced the deeply ideological collision of the Second World War, which resulted in an equally dramatic turnabout, as the Germans endured what Americans then most feared, a grim (albeit partial) communist takeover, and the United States became the staunch ally of the German west in its faceoff with the east. Recently this close partnership has turned into a more perplexed and occasionally suspicious friendship, as the familiar terrain of the cold war is ploughed up. This is a history of extreme reversals is tied inextricably to war and preparations for war.
Transition between vegetative phases in maize: genetic effects and variances and associated markers
Authors: ORDÁS B. , SERRANO L. , ORDÁS A. , BUTRÓN A. , REVILLA P.
Published: June 2009

Transition from juvenile to adult vegetative phase in maize is associated with pest and disease resistance. However, reports are not consistent on the significance and relative importance of additive or dominance genetic effects and variances. The purpose of the present research was to elucidate the genetic effects and variances and to identify molecular markers associated with phase transition. Three cycles of divergent selection were carried out in a maize synthetic accelerating and delaying phase transition. Three and four inbred lines were released from the third cycles of late phase transition (LPT) and early phase transition (EPT), respectively. Generation mean analyses were performed from two LPT×EPT crosses in order to calculate genetic effects and variances. Markers associated with vegetative phase transition were identified by contrasting simple sequence repeat (SSR) alleles between LPT and EPT inbreds and selection cycles, and by testing whether drift could explain the allelic changes observed in the respective third cycles of selection. Juvenile traits are mainly regulated by additive genetic effects and variances, whereas adult traits have a complex regulation involving dominance and epistatic effects. Based on error variances, EPT improves phenotypic stability. The SSRsphi028,phi112andumc1725were associated with selection for phase transition, suggesting that these genome regions are involved in the regulation of vegetative phase transition of maize, although none of the genes previously associated with phase transition has been located in those regions.
Identification of sea bass (Dicentrarchus labrax) nursery areas in the north-western Mediterranean Sea
Authors: Dufour V. , Cantou M. , Lecomte F.
Published: June 2009

Nursery areas of European sea bass (Dicentrarchus labrax, L.) were investigated from spring 2005 to summer 2006 in areas along the French Mediterranean coast of the Gulf of Lion. Nurseries were identified by the presence of settling individuals of sea bass and young juveniles. These nurseries represent different types of sheltered shallow habitats, both natural such as coastal lagoons, estuaries, and artificial such as marinas. Settlement occurred from April to June during both years. The number of settling individuals varied between sites from just a few individuals to several thousand. In one given site, settlement also varied between 2005 and 2006. The size distribution of sampled individuals revealed that several pulses arrived in each nursery. At this stage, sea bass already exhibited a strong orientation capacity but a limited swimming ability. The magnitude of sea bass settlement in marinas requires better environmental management of such artificial areas.
The social organization of sperm whales in the Gulf of California and comparisons with other populations
Authors: Jaquet Nathalie , Gendron Diane
Published: June 2009

Intra-specific variation in social organization provides valuable insights into the selective forces driving social evolution. Sperm whales are distributed globally and live far from shore, thus obtaining large sample sizes on social organization in multiple areas is logistically challenging and few comparative studies exist. In order to address how ecological factors influence sociality, we investigated the social organization of sperm whales in the Gulf of California (GoC) using a long-term study (1998–2004) and compare our results to other published studies. Standard photo-identification and behavioural observation techniques were used. Group size was calculated from photographic mark–recaptures using a Petersen estimator. Social organization was investigated using SocProg 2.3. Mean typical group sizes in the GoC were similar to those in the Galápagos Islands, Chile and Seychelles (24.7, 24.8, 30.4 and 18 individuals respectively), but substantially larger than in the Sargasso Sea, Caribbean and northern Gulf of Mexico (12.0, 6.4 and 6.9 individuals respectively). Sperm whale social organization in the GoC best fitted a constant companion/casual acquaintance model, where permanent units sizes were 12.5 individuals and two units usually associated together to form a group. This structure is similar to the situation in the Galápagos Islands and Chile areas. However, groups were more stable in the GoC than in the South Pacific, as groups stayed together for periods of about 80 days versus about ten days in the Galápagos Islands and Chile. It is likely that differences in the social organization between the study areas in the Pacific and Atlantic Oceans were due to differences in predation pressure and/or food resources. We suggest that, site-specific ecological factors are likely to influence fundamental aspects of sperm whale social organization.
Symposium 1: Joint BAPEN and British Society of Gastroenterology Symposium on ‘Coeliac disease: basics and controversies’ Dietitians are better than clinicians in following up coeliac disease
Authors: Stuckey Claire , Lowdon Jacqui , Howdle Peter
Published: June 2009

It seems obvious to healthcare professionals that patients with coeliac disease should receive regular follow-up. Surprisingly, there is little evidence that patients benefit in terms of reduced morbidity or mortality. However, several authoritative bodies have published guidelines on the management of coeliac disease that recommend regular follow-up. There is good evidence that compliance with a gluten-free diet reduces the risk of complications such as osteoporosis or small bowel lymphoma. Compliance is enhanced particularly by education about the disease and the gluten-free diet and by support from peers or professionals. Such input can be provided by regular follow-up, which thereby should improve compliance and hence long-term health. The consensus of the recommendations for follow-up suggests an annual review by a physician and dietitian. At annual follow-up the disease status can be checked and nutritional advice can be given, including checking the adequacy of, and the compliance with, the gluten-free diet. Complications and associated medical conditions can be sought, genetic risks explained and support and reassurance given. Specialist dietitians have particular expertise in relation to diet and nutritional management; specialist clinicians have a broader range of expertise in many aspects of management of the disease. A team approach for providing follow-up is the ideal, with a clinician and dietitian, both with expertise in coeliac disease, being involved. No one particular group of healthcare professionals is necessarily better than the other at providing follow-up.
Symposium 4: Hot topics in parenteral nutrition Current evidence and ongoing trials on the use of glutamine in critically-ill patients and patients undergoing surgery
Authors: Avenell Alison
Published: June 2009

The amino acid glutamine has numerous important roles including particularly antioxidant defence, immune function, the inflammatory response, acid–base balance and N economy. The present systematic review of randomised controlled trials of nutrition support with glutamine up to August 2008 has found that parenteral glutamine in critical illness is associated with a non-significant reduction in mortality (risk ratio 0·71 (95% CI 0·49, 1·03)) and may reduce infections. However, poor study quality and the possibility of publication bias mean that these results should be interpreted with caution. There is no evidence to suggest that glutamine is harmful in terms of organ failure and parenteral glutamine may reduce the development of organ failure.
Session on ‘Obesity’ Adipose tissue development, nutrition in early life and its impact on later obesity
Authors: Budge H. , Sebert S. , Sharkey D. , Symonds M. E.
Published: June 2009

It is now apparent that one key factor determining the current obesity epidemic within the developed world is the extent to which adipose tissue growth and function can be reset in early life. Adipose tissue can be either brown or white, with brown fat being characterised as possessing a unique uncoupling protein (uncoupling protein 1) that enables the rapid generation of heat by non-shivering thermogenesis. In large mammals this function is recruited at approximately the time of birth, after which brown fat is lost, not normally reappearing again throughout the life cycle. The origin and developmental regulation of brown fat in large mammals is therefore very different from that of small mammals in which brown fat is retained throughout the life cycle and may have the same origin as muscle cells. In contrast, white adipose tissue increases in mass after birth, paralleled by a rise in glucocorticoid action and macrophage accumulation. This process can be reset by changes in the maternal nutritional environment, with the magnitude of response being further determined by the timing at which such a challenge is imposed. Importantly, the long-term response within white adipocytes can occur in the absence of any change in total fat mass. The present review therefore emphasises the need to further understand the developmental regulation of the function of fat through the life cycle in order to optimise appropriate and sustainable intervention strategies necessary not only to prevent obesity in the first place but also to reverse excess fat mass in obese individuals.
Symposium 1: Joint BAPEN and British Society of Gastroenterology Symposium on ‘Coeliac disease: basics and controversies’ Coeliac disease in the twenty-first century
Authors: Dickey William
Published: June 2009

Coeliac disease (CD), traditionally perceived as a rare childhood condition presenting with malabsorption, is instead an autoimmune multisystem disorder usually presenting in adulthood, affecting ⩾1% of the population and linked to the genetic expression of human leucocyte antigens (HLA) DQ2 and DQ8. Presentation occurs most often in the 40–60 years age-group, but potentially at any age. Symptoms attributable to the gut or to malabsorption may be mild, non-specific or absent; under one-third of patients have diarrhoea and almost half are overweight. Histological diagnosis no longer requires small intestine villous atrophy. The Marsh classification recognizes increased intraepithelial lymphocytes and crypt hyperplasia with intact villi as part of the gluten enteropathy spectrum, while some individuals have more subtle abnormalities identified only on electron microscopy. Serological testing for CD autoantibodies (to endomysium and tissue transglutaminase) has revolutionized diagnosis, shifting the process towards primary care. However, a substantial number of patients with CD are seronegative, particularly those without villous atrophy. The autoantibody to endomysium may be produced before histological change. The immune response to transglutaminase is crucial to the disease process. An exciting new development is the link between antibodies to organ-specific transglutaminases and clinical presentation; transglutaminases 2 (gut), 3 (skin) and 6 (nervous system). Negative testing for CD does not preclude its development later and HLA testing may allow ‘once and for all’ exclusion. In conclusion, an increasing proportion of patients with CD do not meet the ‘classic’ picture of malabsorption, positive serological testing and villous atrophy. Insisting on all these criteria for diagnosis will result in under diagnosis.
Change in teachers' ratings of attention problems and subsequent change in academic achievement: a prospective analysis
Authors: Breslau N. , Breslau J. , Peterson E. , Miller E. , Lucia V. C. , Bohnert K. , Nigg J.
Published: June 2009

Background

Recent research has documented a link between attention problems at school entry and later academic achievement. Little is known about the association of change in attention problems during the early school years with subsequent change in academic achievement.

Method

A community-based cohort was followed up and assessed for attention problems at ages 6 and 11 (Teacher Report Form; TRF) and for academic achievement in math and reading at ages 11 and 17 (Woodcock–Johnson Psycho-Educational Battery). Complete data were available on 590 children (72% of the initial sample). Ordinary least squares regressions were used to estimate change in academic achievement from age 11 to age 17 in relation to change in TRF-attention problems from age 6 to age 11. Children's IQ and family factors were statistically controlled.

Results

Change in teachers' ratings of attention problems from age 6 to age 11 was negatively associated with change in math and reading from age 11 to age 17, controlling for children's IQ and family factors. Externalizing problems had no significant association with change in math or reading, when added to the multivariable model.

Conclusions

Increases in teacher-rated attention problems from age 6 to age 11 were followed by declines in academic achievement from age 11 to age 17; decreases were followed by gains. The results underscore the need for research on the course of attention problems, the testing of interventions to address children's early attention problems and the evaluation of their effects on subsequent academic achievement.
Is the antidepressive effect of second-generation antidepressants a myth?
Authors: Bech P.
Published: June 2009

Two recent meta-analyses on second-generation antidepressants versus placebo in mild to moderate forms of major depression, based on data on all randomized clinical trials using the Hamilton Depression Scale (HAMD) submitted to FDA, have shown an effect size of ∼0.30 in favour of antidepressants in the acute therapy of major depression. The clinical significance of an effect size at this level was found to be so poor that these meta-analyses have subscribed to the myth of an exclusively placebo-like effect of second-generation antidepressants. A re-allocation of HAMD items focusing on those items measuring severity of clinical depression, the HAMD6, has identified effect sizes of ⩾0.40 for second-generation antidepressants in placebo-controlled trials for which even a dose–response relationship can be demonstrated. In the relapse-prevention phase during continuation therapy of patients with major depression, the advantage of second-generation antidepressants over placebo was as significant as in the acute therapy phase. To explore a myth is not to deny the facts but rather to re-allocate them.
Efficacy and effectiveness of individual family intervention on social and clinical functioning and family burden in severe schizophrenia: a 2-year randomized controlled study
Authors: Girón M. , Fernández-Yañez A. , Mañá-Alvarenga S. , Molina-Habas A. , Nolasco A. , Gómez-Beneyto M.
Published: June 2009

Background

Empirical evidence of the efficacy and effectiveness of psychosocial family intervention and of the specificity of its effects on the course of schizophrenia is limited. The aim was to study the efficacy and effectiveness of psychosocial family intervention with regard to clinical and social functioning and family burden after controlling for compliance and several prognostic factors.

Method

A 2-year randomized controlled trial with blind assessments. Fifty patients with DSM-IV schizophrenia and persistent positive symptoms and/or previous clinical relapse were allocated to psychosocial family intervention, individual counselling and standard treatment versus individual counselling and standard treatment.

Results

Family intervention was associated with fewer clinical relapses, hospitalizations and major incidents, and an improvement in positive and negative symptoms, social role performance, social relations, employment and family burden. The reduction in hospitalizations in the family intervention group was significantly greater than that observed in the group of patients who refused to participate but this was not the case for the control group. The effects of family intervention were independent of compliance and prognostic factors.

Conclusions

Family intervention is effective in severe schizophrenia independently of compliance and prognostic factors.
Totalitarianism Revisited
Authors: Brooks Jeffrey
Published: June 2009

“Totalitarianism” is a powerful word rich in historical associations and rebounding in current political usage. The four books under review reflect both the term's range of usage and the enduring fascination with the phenomena it described. Totalitarianism's initial terminological siblings, “nazism” and “communism,” are applied chiefly to the original historical subjects that generated them. A close political cousin, “fascism,” long ago escaped its close ideological family and is applied to everything from brutal police to road hogs. In contrast, “totalitarianism,” formerly confined to a narrow political as opposed to a cultural context, is suddenly in play. In recent issues of the New York Times, David Brooks excoriates Iraqi proponents of “totalitarian theocracy” (5/16/2004); President Bush deplores the terrorists’ “totalitarian ideology” (5/29/05), and Condoleezza Rice abhors Iran as a “totalitarian state” (5/29/2005). A Central Asian despot is characterized as a “fragile totalitarian” in a feature by David E. Sangler (5/29/2005), and the group of army officers (the Military Council for Justice and Democracy) that overthrew President Maouya Sidi Ahmed Taya in Mauritania in August 2005 defend their decision “to put an end to the totalitarian practices of the deposed regime.” Totalitarianism is back, but what does it mean?
Early metalinguistic awareness of derivational morphology: Observations from a comparison of English and French
Authors: DUNCAN LYNNE G. , CASALIS SÉVERINE , COLÉ PASCALE
Published: June 2009

This cross-linguistic comparison of metalinguistic development in French and English examines early ability to manipulate derivational suffixes in oral language games as a function of chronological age, receptive vocabulary, and year of schooling. Data from judgment and production tasks are presented for children aged between 5 and 8 years in their first, second, or third school year in the United Kingdom and France. The results suggest that metamorphological development is accelerated in French relative to English. The French advantage encompasses knowledge of a broader range of suffixes and a markedly greater facility for generalizing morphological knowledge to novel contexts. These findings are interpreted in relation to the word formation systems of English and French, and the educational context in each country.
Role of working memory in children's understanding spoken narrative: A preliminary investigation
Authors: MONTGOMERY JAMES W. , POLUNENKO ANZHELA , MARINELLIE SALLY A.
Published: June 2009

The role of phonological short-term memory (PSTM), attentional resource capacity/allocation, and processing speed on children's spoken narrative comprehension was investigated. Sixty-seven children (6–11 years) completed a digit span task (PSTM), concurrent verbal processing and storage (CPS) task (resource capacity/allocation), auditory–visual reaction time (AVRT) task (processing speed), and the Test of Narrative Language. Correlation and regression analyses examined the association between the memory variables and comprehension. The main findings were (a) CPS and AVRT correlated with comprehension and (b) after accounting for age, CPS accounted for a significant 7.9% of unique variance and AVRT accounted for another significant 5.2%. The results indicate that resource capacity/allocation and processing speed are important to children's ability to understand spoken narrative.
Experimental evaluation of open-loop swimming control for a robotic fish using electrostatic film motors
Authors: Yamashita Norio , Zhang Zu Guang , Yamamoto Akio , Gondo Masahiko , Higuchi Toshiro
Published: June 2009

We have developed an underwater robotic fish using a unique three-layer electrostatic film motor. In the robotic fish, the unique motor actuates a flexible caudal fin to propel the robot via an elaborate power transmission system. In the present study, we describe the major disadvantages of the previous prototype of the robotic fish and improvements of the prototype. In addition, we present experimental evaluations related to the control parameters and locomotion performance of the robotic fish. These control parameters include the frequency and initial phase of AC voltage, and the amplitude and period of frequency sweeping. A simple theoretical model concerning the power transmission system of the robotic fish is also analyzed to provide a possible explanation for the unique swimming control. By appropriately adjusting these control parameters, we achieve cruising, emerging, submerging, and turning of the robotic fish even though only the caudal fin is active. Finally, we show smooth human-operated turn-around motion similar to that seen in real fish. Based on these experimental results, we further clarify the relationships between the open-loop motor pattern and motion parameters.
Teaching composing in secondary school: a case study analysis
Authors: Bolden Benjamin
Published: June 2009

This article reports a case study of an experienced teacher of composing working with secondary school students in a large urban centre in Ontario, Canada. Results suggest authentic assignments connect student composing to the ‘real world’, and so have meaning and life beyond the music classroom. Teachers can facilitate the development of theoretical music knowledge by supporting and enhancing the experiential learning that students accomplish on their own, through composing. Offering suggestions for change to compositions-in-progress, and cultivating a classroom ethos where students exchange this service amongst themselves, serves to enhance composing potential. By helping students infuse their work with personal knowledge, experiences, and interests, teachers can increase students’ meaningful involvement in classroom composing.
Children's graphical notations as representational tools for musical sense-making in a music-listening task
Authors: Reybrouck Mark , Verschaffel Lieven , Lauwerier Sofie
Published: June 2009

This article tries to answer two related questions: (i) what do children hear while listening to and making sense of music? and (ii) what kind of representational tools can be used to assess this sense-making? To answer these questions, we set up two empirical studies in which 89 children – 8–9-year-olds and 11–12-year-olds (first study) – and 331 children – 8–10-year-olds and 11–13-year-olds, with and without extra music training (second study) – were exposed to a music listening task. The aim of the studies was to get an overall picture of the variety of children's musical representations by means of their graphical notations, and to investigate the impact of age, formal musical training and the characteristics of the musical fragment on these notations. A major finding of the first study was the emergence of two main categories of notations, namely ‘global’ and ‘differentiated’ notations, with a very strong dominance of global over differentiated ones and a negligible impact of subject and task variables. The second study, in which we presented researcher-generated instead of existing musical fragments, yielded a larger number of differentiated notations, and a considerable impact of age and formal musical education as well as of the musical characteristics on these notations. Both studies were ascertaining studies with the aim to describe and analyse the development of children's graphical notations under given instructional conditions. To account for some of the limitations of these studies, some additional design-based research is suggested. Extensive findings/exemplars of both studies can be found on the Cambridge University Press website.
Processes of alienation: Marx, Orff and Kodaly
Authors: Benedict Cathy
Published: June 2009

Using Marx as a lens through which to interrogate music methodology, in particular those espoused by Orff and Kodaly, this article suggests that rather than the free play and creativity Orff and Kodaly intended, the implementation of these methods in a strict and unmindful manner, often alienates both teacher and student from musicking. Thus these methods have become more real than the music itself and as such, music making within them is abstracted from the use-value of musicking and consequently exchanged as a commodity. The article explains how methods become a form of production that serves to reproduce systems of domination as well as a very particular form of cultural capital. This lens also allows us to realise that, as we move farther away from the process of inquiry originally embedded in the conception and construction of these musical engagements, the educative process becomes more and more myopic. This, in turn, determines, delineates and narrows possibilities of and for meaningful learning.
INTEGRATED MARKOV-SWITCHING GARCH PROCESS
Authors: Liu Ji-Chun
Published: June 2009

This paper investigates stationarity of the so-called integrated Markov-switching generalized autoregressive conditionally heteroskedastic (GARCH) process, which is an important subclass of the Markov-switching GARCH process introduced by Francq, Roussignol, and Zakoïan (2001,Journal of Time Series Analysis22,197–220) and a Markov-switching version of the integrated GARCH (IGARCH) process. We show that, like the classical IGARCH process, a stationary solution with infinite variance for the integrated Markov-switching GARCH process may exist. To this purpose, an alternative condition for the existence of a strictly stationary solution of the Markov-switching GARCH process is presented, and some results obtained in Hennion (1997,Annals of Probability25, 1545–1587) are employed. In addition, we also discuss conditions for the existence of a strictly stationary solution of the Markov-switching GARCH process with finite variance, which is a modification of Theorem 2 in Francq et al. (2001).
A BIAS-CORRECTED NONPARAMETRIC ENVELOPMENT ESTIMATOR OF FRONTIERS
Authors: Bădin Luiza , Simar Léopold
Published: June 2009

In efficiency analysis, the production frontier is defined as the set of the most efficient alternatives among all possible combinations in the input-output space. The nonparametric envelopment estimators rely on the assumption that all the observations fall on the same side of the frontier. The free disposal hull (FDH) estimator of the attainable set is the smallest free disposal set covering all the observations. By construction, the FDH estimator is an inward-biased estimator of the frontier.

The univariate extreme values representation of the FDH allows us to derive a bias-corrected estimator for the frontier. The presentation is based on a probabilistic formulation where the input-output pairs are realizations of independent random variables drawn from a joint distribution whose support is the production set. The bias-corrected estimator shares the asymptotic properties of the FDH estimator. But in finite samples, Monte Carlo experiments indicate that our bias-corrected estimator reduces significantly not only the bias of the FDH estimator but also its mean squared error, with no computational cost. The method is also illustrated with a real data example. A comparison with the parametric stochastic frontier indicates that the parametric approach can easily fail under wrong specification of the model.
The genetic basis of male infertility
Authors: Chandley Ann C
Published: June 2009

Amongst men who attend fertility problems clinics, just over 10% are diagnosed to be oligospermic (< 5 × 106sperm per ml) or azoospermic, with no known aetiological explanation. Amongst the many possible causes of impaired sperm production there is a genetic component, a pointer to the possible location of some of the responsible genes being found in 1976 when Tiepolo and Zuffardi discovered six azoospermic individuals with a deleted Y chromosome. In each individual, the long arm of the Y chromosome had lost its distal fluorescent segment as well as part of the nonfluorescent euchromatin lying proximal to it (Figure 1). They hypothesized that factors important in spermatogenesis might lie at the interface between fluorescent and nonfluorescent material. The locus, AZFor ‘azoospermia factor’, was subsequently mapped, using collections of deleted Y chromosomes, to interval six of the long arm and it lies within cytological band Yq11.23 (Figure 2).

In an effort to summarize the potential risks of therapeutic insemination by donor (TID), including a review of cases of disease attributed to donor semen, a MEDLINE literature search was conducted to identify all published case reports of transmissible diseases occurring in donor semen recipients published in English between 1975 and 1992. The reference list for each article was reviewed to locate additional published case reports. Pertinent case reports were compiled according to disease agent and classified into viral, bacterial and other categories.
Integrins in the endometrium
Authors: Lessey Bruce A , Castelbaum Arthur J
Published: June 2009

The endometrium expresses many of the same integrins displayed by other tissues. Endometrial epithelial cells maintain the ‘classic’ epithelial integrins, including α2, α3, α6, and β4, while the stroma expresses the fibronectin receptor, α5β1. During the menstrual cycle, the endometrium undergoes dynamic changes in morphology in preparation for implantation. With these histological changes are concomitant alterations in integrin expression that appear to ‘frame’ the window of implantation, by the co-expression of glandular αvβ3 and α4β1 during days 20 to 24 of the menstrual cycle. The changes in integrin expression shift from epithelial to stroma predominance late in the menstrual cycle, extending into early pregnancy. Decidual integrins that appear upregulated in pregnancy include α1β1, α3β1, α6β1 and αvβ3. Markers of uterine receptivity hold promise for a better understanding of the implantation process and may help to explain many different types of infertility. These markers will be essential for monitoring and improving infertility therapies. The importance of integrins in the human endometrium now seems well established and promises to be an area of great clinical and basic science activity in the future.
Experiences with intracytoplasmic sperm injection
Authors: Lanzendorf Susan E
Published: June 2009

Mammalian fertilization, whether it takes place within the female reproductive tract or within a laboratory dish, is comprised of many processes which must follow a specific sequence. The spermatozoon must bind to and pass through the zona pellucida, fuse with the oolemma and become incorporated into the cytoplasm of the oocyte. Fusion of the two gametes triggers oocyte activation, resulting in exocytosis of the cortical granules and completion of the second meiotic division of the oocyte. A block in one or more of these processes, due either to abnormalities in the spermatozoon or oocyte, may result in fertilization failure.
Cytokines and embryo/endometrial interactions
Authors: Sharkey Andrew
Published: June 2009

Experimental animal models have shown that thein vitroembryo culture involved in many treatments for infertility results in a dramatic reduction in embryo viability. Recent advances in methodology such as RT-PCR for localization and quantitation of cytokines and their receptors, are revealing the role that this group of growth factors plays in the basic physiology of embryo development and the process of implantation itself. These studies offer the likelihood of dramatically improvingin vitroembryo culture in humans and other species by supplementation of culture medium with growth factors or antagonists to improve embryo viability and hence implantation rates.
Molecular biology of sperm maturation in the human epididymis
Authors: Kirchhoff Christiane
Published: June 2009

Male infertility is a frequent cause of childlessness, and, indeed, a comparison of the contributions to conception failure made by male and female factors shows them to be equally frequent. In practice, male infertility appears to be resistant to most treatments. However, the major reason for this may be that often attempts are carried out without knowing the cause of the problem. Unlike in women, obstructions and hormonal disorders are rare in male infertility. Rather, it would appear that sperm disorders are the most common cause, reflecting a variety of pathogenetic mechanisms. Defects in sperm morphology, defective sperm movement, deficient development or functional failure of the acrosome, and the excessive generation of reactive oxygen species are changes that are often seen in infertile semen, but little is known about their aetiology. In 5–10% of men being treated for infertilty, an autoimmune reaction against spermatozoa is observed. Although the correlation between the presence of systemic antisperm antibodies and fertility potential is poor, the appearance of sperm-bound antibodies of immunoglobulin class IgA in semen seems to be closely associated with infertility. Studies in laboratory animals and humans have shown that complementary adhesion molecules are located on the surface of oocytes and spermatozoa. These molecules interact and lead to gamete fusion. Abnormalities in these molecules on the sperm surface might be expected to contribute to male infertility. However, their clinical significance has not yet been documented, and the molecular basis of human gamete interaction is far from being understood. Therefore, the key to understanding male infertility may lie in basic research which directly targets the fundamental cellular and molecular biology of the human spermatozoon.
The epididymal influence on sperm maturation
Authors: Cooper Trevor G
Published: June 2009

Consideration of the function of the epididymis has undergone profound changes over the last century during which it has moved from a largely neglected male reproductive organ to one that is an increasingly exploited source of sperm for assisted reproduction strategies. From histological studies in the lizard1 it was considered that, ‘…the cells lining the epididymal canal produce a material necessary for the spermatozoa during their passage through the organ …’ whereas a fertility study with guinea-pigs stated boldly that, ‘… changes undergone [by spermatozoa in the epididymis] are not conditioned by some specific action of epididymal secretion …’. The former view found favour in a review of the literature which concluded that, ‘… there are specific epididymal secretions necessary for sperm maturation and survival …’, although the nature of the secretions were not then known. However, this concept, currently held by most of those studying the epididymis of animals, was again contradicted on the basis of clinical work: ‘… it certainly is possible for sperm that have never passed through any length of the epididymis at all to mature on their own …’.
Pathogenesis and treatment of hirsutism in late-onset congenital adrenal hyperplasia
Authors: Carmina E
Published: June 2009

Late-onset or nonclassic hyperandrogenic congenital adrenal hyperplasia (CAH) is an attenuated deficiency of 21-hydroxylase, 3β-ol-hydroxysteroid dehydrogenase or 11β-hydroxylase which presents during childhood or adolescence and leads to an increased secretion of adrenal androgens. Many reviews of the genetic or hormonal characteristics of these syndromes have been published, but relatively little attention has been paid to the pathogenesis and treatment of hirsutism which, in most young women, is the main complaint. In fact, it is generally assumed that the hirsutism is strictly related to the increased secretion of adrenal androgens and that glucocorticoids are the treatment of choice. However, some recent studies have shown that the ovary contributes to the hyperandrogenism of these patients and some alternative therapies have been proposed. This forms the matter of the present review.
Cigarette smoking as a cause of delay in conception
Authors: Zenzes Maria Teresa
Published: June 2009

Epidemiological studies relating cigarette smoking to the ability to conceive and maintain a pregnancy provide information on the clinical significance of smoking on reproductive health. Cigarette smoking by females has significantly increased in the decades after World War II, and now has an average initiation at ages 18–20 years. Maternal smoking is a hazard to the general health, the reproductive health and the life of both mother and child. Gestational smoking renders the fetus a passive smoker. This can result in fetal and neonatal death and in reduced fecundity of adult daughters.
The value of salpingoscopy in tubal infertility
Authors: Brosens Ivo A
Published: June 2009

Tubal factors are estimated to account for 15–20 per cent of infertility. The incidence not only depends on the patient population but is probably also underestimated since evaluation of tubai function is largely restricted to the appraisal of its patency. Consequently the treatment of tubai infertility is primarily focused on the restoration of tubai patency. That infertility frequently persists in spite of successfully restored patency and that tubal pregnancy frequently occurs after infertility surgery suggest that underlying disease has not been diagnosed.
