On the detection of emotional facial expressions: Are girls really better than boys?
Authors: LoBue Vanessa , DeLoache Judy S.
Published: October 2009

One facet of Vigil's socio-relational framework of expressive behaviors (SRFB) suggests that females are more sensitive to facial expressions than are males, and should detect facial expressions more quickly. A re-examination of recent research with children demonstrates that girls do detect various facial expressions more quickly than do boys. Although this provides support for SRFB, further examination of SRFB in children would lend important support this evolutionary-based theory.
Sex differences in emotion expression: Developmental, epigenetic, and cultural factors
Authors: Izard Carroll E. , Finlon Kristy J. , Grossman Stacy R.
Published: October 2009

Vigil's socio-relational framework of sex differences in emotion-expressive behavior has a number of interesting aspects, especially the principal concepts of reciprocity potential and perceived attractiveness and trustworthiness. These are attractive and potentially heuristic ideas. However, some of his arguments and claims are not well grounded in research on early development. Three- to five-year-old children did not show the sex differences in emotion-expressive behavior discussed in the target article. Our data suggest that Vigil may have underestimated the roles of epigenetic and cultural factors in shaping emotion-expressive behavior.
Biofeedback mechanisms between shapeable endogen structures and contingent social complexes: The nature of determination for developmental paths
Authors: Ferber Sari Goldstein
Published: October 2009

Biofeedback mechanisms (a) between individuals, (b) between the individual and the society structures which shape individual cognitions, and (c) within the individual genetic biochemical circulation, may explain the diversity of trustworthiness potential and the option of mutual trust for every individual in any given society.
When organization meets emotions, does the socio-relational framework fail?
Authors: Basso Frédéric , Oullier Olivier
Published: October 2009

We suggest that the framework proposed by Vigil is useful in laboratory contexts but might come up short for in vivo social interactions. Emotions result from cost-benefits trade-offs but are not solely generated at the individual level to establish emotional social spheres. In organizational contexts, emotion expression can be a constitutive part of a professional activity, and observed sex differences might vanish.
The socio-relational framework of expressive behaviors as an integrative psychological paradigm
Authors: Vigil Jacob Miguel
Published: October 2009

This response shows how the socio-relational framework of expressive behaviors may be used to understand and predict social psychological processes, beyond sex differences in the expression of emotion. I use this opportunity to elaborate on several key concepts on the epigenesis of evolved social behaviors that were not fully addressed in the target article. These are: evidence of a natural history of masculine and feminine specialization (sect. R1); phenotypic plasticity and range of reactivity of social behaviors (sect. R2); exploitive and protective functions of social behaviors (sect. R3); and the role of cognition in some affective responses (sect. R4). I conclude by highlighting (in sect. R5) future directions for psychological research from a socio-relational basis.
On the richness and limitations of dimensional models of social perception
Authors: Todorov Alexander
Published: October 2009

The two-dimensional model of social relations outlined in the target article has striking convergence with empirically derived dimensional models of interpersonal perception, inter-group perception, and face evaluation. All these models posit two-dimensional structures related to perceptions of valence/affiliation and power/status. Although these models are parsimonious, they may be insufficient to account for behaviors in specific contexts.
Smiling reflects different emotions in men and women
Authors: Vazire Simine , Naumann Laura P. , Rentfrow Peter J. , Gosling Samuel D.
Published: October 2009

We present evidence that smiling is positively associated with positive affect in women and negatively associated with negative affect in men. In line with Vigil's model, we propose that, in women, smiling signals warmth (trustworthiness cues), which attracts fewer and more intimate relationships, whereas in men, smiling signals confidence and lack of self-doubt (capacity cues), which attracts numerous, less-intimate relationships.
A socio-relational framework of sex differences in the expression of emotion
Authors: Vigil Jacob Miguel
Published: October 2009

Despite a staggering body of research demonstrating sex differences in expressed emotion, very few theoretical models (evolutionary or non-evolutionary) offer a critical examination of the adaptive nature of such differences. From the perspective of a socio-relational framework, emotive behaviors evolved to promote the attraction and aversion of different types of relationships by advertising the two most parsimonious properties ofreciprocity potential, or perceived attractiveness as a prospective social partner. These are the individual's (a)perceived capacityor ability to provide expedient resources, or to inflict immediate harm onto others, and their (b)perceived trustworthinessor probability of actually reciprocating altruism (Vigil 2007). Depending on the unique social demands and relational constraints that each sex evolved, individuals should be sensitive to advertise “capacity” and “trustworthiness” cues through selective displays of dominant versus submissive and masculine versus feminine emotive behaviors, respectively. In this article, I introduce the basic theoretical assumptions and hypotheses of the framework, and show how the models provide a solid scaffold with which to begin to interpret common sex differences in the emotional development literature. I conclude by describing how the framework can be used to predict condition-based and situation-based variation in affect and other forms of expressive behaviors.
The role of emotions in adaptations for exploitation
Authors: Buss David M.
Published: October 2009

Emotion expression serves functions in exploitative resource-acquisition strategies that may not include relationship reciprocity. These include rendering victims more exploitable and signaling one's status as non-exploitable. A comprehensive theory of emotion expressions must explain their role in adaptations for exploitation, as well as evolved defenses against those pursuing a strategy of exploitation.
Challenges in Music Education Facing the New South Africa
Authors: Oehrle Elizabeth
Published: October 2009

South Africa is undergoing dynamic changes affecting all aspects of life, and legacies of the previous regime have a bearing on these changes. Music educators informal institutions face many challenges. Music-making in the informal sector is extensive, ongoing and relevant. Today, one of the greatest challenges for music educators in the formal sector is to realise the importance and value of developing a philosophy and process of music education that emanates and evolves from musics and musical practices existing in southern Africa.
Missing Messages: Lessons from Tanzania
Authors: Floyd Malcolm
Published: October 2009

How can music help to create a culture of tolerance when there are fundamental problems in decoding the messages in the musk of others? There is quite good access in British and other schools to musical materials from Africa, and use has been made of them, but there is a question as to whether this use is appropriate and acceptable. The concept of ownership of such music is briefly discussed, and the relative effectiveness of its transmission. This is then set in the contexts of Music Education and the strength of Christianity in contemporary Tanzania, including some of the problems perceived by Tanzanian students and teachers. These contexts have to be acknowledged, and the article concludes with two suggestions for making the inclusion of African music in British schoob a more transformative experience, ideally through direct links with sources of African music in Africa.
Curricular Innovations in Traditional Music: A Case Study of Zimbabwean Music Teacher Education
Authors: de Lowerntal Elizabeth
Published: October 2009

The attainment of Zimbabwean independence in 1980 resulted in a variety of pressures on the curriculum for the education of music teachers. These pressures included dissatisfaction with the Eurocentric bias of the existing curriculum and demands for shifting the bias of education towards the promotion of previously marginalised aspects of Zimbabwean culture. This paper outlines the effects of these pressures on curricular innovations in Zimbabwean traditional music at Hillside Teachers' College, Bulawayo, and explores the possibilities for the future development of traditional music curriculum.
Popular Music in Nigeria: Patronising Attitude or Benign Complacency?
Authors: Okafor Richard
Published: October 2009

The development of musicians and the continuity of the musical art should be the main thrust of music education. The institutions of education should therefore be equipped to mould the development of music in society and to make the strongest input into musical expressions that are fashionable, acceptable and available. Formal music education came to Nigeria by way of Western institutions, drawing from the cultural traditions of Western societies. On the other hand, the media and other agencies have brought in other types of music acceptable in Western societies outside their academic sectors. Musical and cultural contact has given birth to the contemporary popular music of Nigeria that integrates Nigerian and non-Nigerian elements. With the growth of city life, commerce, industry and communication, this music has grown in popularity, in some cases sweeping every other thing aside. The attendant ‘pop phenomenon’ also means that cultural intrusion from outside Nigeria has grown more menacing. Who controls the popular music in Nigeria today? This paper tries to answer this question and in addition presents some data on the prevailing perspectives in the hope that the Nigerian Government and all music educators should range plans and solutions against them.
The Identification of Needs for the Provision of In-service Training in Music Education in Botswana
Authors: Phuthego Mothusi
Published: October 2009

This study investigates the in-service training needs of the primary school generalist teacher in Botswana. The findings established that singing is a major cross-curricular activity in schools. Dance on the other hand, despite being the most popular form of entertainment in and outside school, is not regarded as an aspect of music education. Instrumental teaching is virtually non-existent. Teachers' interests in further musical training are influenced by a misconception that singing should be the main activity in music lessons. As a result most are only interested in improving their skills in areas that will improve their singing, such as theory of music to aid sight reading.
Teaching Culture: Thoughts from Northern Ghana
Authors: Wiggins Trevor
Published: October 2009

This article considers ideas and issues raised by an examination of the function of education, particularly music education in Ghana. There are many musical traditions in Ghana that the people want to pass on to the younger generation. How are these to be taught or learned? Where are the duties and boundaries of formal education to be drawn? What can be expected of parents and family? What is the situation for the teacher, given that few teachers return to their native area after training at a centralised institution? The article is based around an interview with the Paramount Chief (Naa) Puoure Puobe Chiir VII of Nandom in the Upper West Region of Ghana. He is one of twenty-five members of the National Council of State of Ghana (a non-elected Upper Chamber) and, as mentioned in the interview, vice-president of the National House of Chiefs and Chairman of its Research Committee.
Cost-effectiveness of Misoprostol in Sweden
Authors: Jönsson Bengt , Haglund Ulf
Published: October 2009

Based on an American multicenter study, an economic evaluation of prophylactic misoprostol was undertaken in Sweden. The study included 420 patients with osteoarthritis and nonsteroidal anti-inflammatory drug (NSAID)-associated abdominal pain, but no gastric ulcer at inclusion. The frequency of ulcer development with and without prophylactic misoprostol was assessed at 21.7% and 5.6%, respectively, for a 3-month period. All costs for drugs, ambulatory care, hospital care, loss of production, as well as other factors such as dosage and compliance, were transferred to Swedish conditions. It was concluded that in patients with osteoarthritis and NSAID-induced abdominal pain, prophylaxis with misoprostol is cost-effective in Sweden, which is similar to what is found for other countries. A prerequisite for this result is a frequency of ulcer development of 15%. A patient compliance to prophylactic treatment of more than 60% is also presupposed (79% was observed in the above study). Due to the high age of the osteoarthritis patient population, the cost-effectiveness is influenced to only a minor extent by whether indirect costs are included in the calculation.
Nonexperimental Evaluation of the Effectiveness of a Screening Program for Lung Cancer
Authors: Ebeling K. , Nischan P.
Published: October 2009

The effectiveness of screening to control lung cancer was examined in the German Democratic Republic by analyzing data from a cancer registry and incidence and mortality rates for lung cancer relative to different screening policies, and by two case-control studies. Mortality from lung cancer did not appear to be affected by the screening programs studied. The high cost of mass screening, combined with uncertainty about the benefits of early treatment of lung cancer, outweigh the vague advantages of such screening.
Health Care Technology Transfer in Latin America and the Caribbean
Authors: Coe Gloria A. , Banta David
Published: October 2009

The greatest problem concerning health care technology for developing countries is that they are dependent upon the industrialized world for technology. The only short-term solution to this problem is to improve the choices that are available to them. This goal will require changes in the structure and processes of policy making. A particular difficulty for these countries is the lack of trained personnel in fields related to technology assessment.

Published: October 2009

Hospital-based “firms” provide a means for combatting the fragmentation experienced by both patients and caregivers in the modern teaching hospital environment. A “firm” is an academic group practice that includes attending physicians, physician trainees, nurses, other staff, and patients. Each person's relationship with a firm lasts throughout his or her association with a particular institution. This article describes the firm system that was recently implemented on the Medical Service of the Cleveland VAMC. This system incorporates both inpatient and outpatient general medical services and provides for unbiased assignment of patients, physicians, and nurses.
Quality Assessment of Medical Research and Education
Authors: Eriksson Håkan
Published: October 2009

Different aspects of the process of evaluating research and education are discussed, using the discipline of medicine as a model. The focus is primarily on potential problems in the design of an evaluation. The most important aspects of an assessment are: to create confidence in the evaluation among scientists and/or teachers who are being assessed before beginning; to find experts for whom the scientists and/or teachers have professional respect; to choose assessment methods in relation to the focus, level, and objectives of the evaluation; and to make the report of the evaluation's findings short and explicit.
Economic Evaluation of Hypertension Treatment
Authors: Johannesson Magnus
Published: October 2009

A computer simulation model shows that the cost-effectiveness of treating hypertension is highly sensitive to different assumptions about the effectiveness of treatment, the outcome measure, the cost concept, the discounting of effects, and the duration of therapy. Cost-effectiveness analysis should be supplemented by another approach–cost-benefit analysis based on the contingent valuation (CV) method (the measurement, by survey, of willingness to pay). The CV method is tested in two empirical applications that indicate that it is possible to use the method in this area. Its results should be interpreted with caution, however, since the reliability and validity of the method is not yet established.
The Use of Risk-adjusted Complication Rates to Compare Hospitals Performing Coronary Artery Bypass Surgery or Angioplasty
Authors: Hartz Arthur J. , Kuhn Evelyn M. , Green Robert , Rimm Alfred A.
Published: October 2009

A hospital's quality of care is generally assessed by a review of individual records. This study used unadjusted and risk-adjusted complication rates to measure the quality of care for hospitals that perform coronary artery bypass surgery or angioplasty. Hospitals differed greatly in their complication rates. Only a small percentage of this difference was due to differences in the risks that patients faced.
The Global Capacity for Manufacturing Vaccines: Prospects for Competition and Collaboration Among Producers in the Next Decade
Authors: Robbins Anthony , Arita Isao
Published: October 2009

Can the world respond to the demands of the Children's Vaccine Initiative (CVI) to produce large quantities of affordable vaccines that have never been manufactured previously? Vaccines for the world's birth cohort of 150 million will continue to be produced in the countries that use the greatest part of the global vaccine supply. Thus, the CVI will rely on increased self sufficiency in vaccine production in the developing world and “shared development” of new and improved vaccines. The CVI's goal is to direct product development to meet the needs of immunization programs, but it must not neglect production. Thus, from the start, investment at the front end of the development and production sequence requires attention to the ultimate production capacity.
New Challenges in Quality Control and Licensure: Regulation
Authors: Brown Kenneth R. , Douglas R. Gordon
Published: October 2009

The Children's Vaccine Initiative (CVI) will result in profound changes in immunization practice. Before the CVI is fully developed, it will present numerous challenges to regulatory practice that will require new applications of existing ideas and innovative solutions to practical issues, especially in combining existing vaccines.
Adjuvants and Immune Enhancement
Authors: Allison Anthony C.
Published: October 2009

Adjuvants increase cell-mediated and humoral immune responses to specific antigens. Used with recombinant viral antigens, they can elicit the production of T lymphocytes that lyse target cells, expressing the antigen in a genetically restricted fashion. Adjuvants can augment the production of interferon-gamma, thereby favoring the production of protective antibody isotopes, such as immuno-globulin G2a in the mouse. Modern adjuvants display the efficacy of Freund's complete adjuvant without its side effects. One such adjuvant is Syntex adjuvant formulation, a synthetic analogue of muramyl dipeptide in a microfluidized squalane/squalene-in-water emulsion. Monophosphoryl lipid A in a similar lipid emulsion is also effective. Immune-stimulating complexes of saponin and antigens elicit potent cell-mediated and humoral responses. A purified saponin component has adjuvant activity with reduced side effects; liposomes also can have adjuvant activity. Administering antigens in adjuvants can overcome low responsiveness in very young and old experimental animals and in those that are genetically low responders. Adjuvants are likely components of a new generation of recombinant and subunit vaccines.
Novel Approaches to Controlled-Release Antigen Delivery
Authors: Cohen Smadar , Alonso Maria J. , Langer Robert
Published: October 2009

Two strategies for vaccine-delivery systems, both relying on concepts of controlled-release technology, are described in this review. The first strategy involves using biodegradable polymer microspheres for parenteral and oral delivery of antigens. The other strategy combines two technologies, the encapsulation of antigen within liposomes and liposome encapsulation in hydrogels, to protect them from a rapid degradation in vivo. Both strategies have shown promise in terms of increasing the immunogenicity of poorly immunogenic peptides and protein vaccines. The microencapsulation process, antigen stability, mechanism of antigen release, and optimal release kinetics for vaccine delivery are reviewed, and the strengths and weaknesses of each approach are discussed.
Live Attenuated Vaccine Vectors
Authors: Mekalanos John J.
Published: October 2009

Several different live attenuated vaccine vectors currently are under development. These vaccines are composed of living viruses or bacteria that are innocuous to the host but can replicate in host tissues and induce immune responses. The genes encoding foreign antigens can be inserted into these vectors to produce multivalent vaccines that promise to induce immunity to more than one target disease after the administration of a single dose of vaccine.
Immunization of the Neonate
Authors: Lawton Alexander R.
Published: October 2009

The generation of diversity of T and B cells begins early in gestation. Selective restrictions in expression of V genes occur in fetal life, but insufficient clonal diversity is not likely to limit newborn immune capabilities. The functional immaturity of neonatal T and B cells is beginning to be defined. Virgin T cells lack the capacity to produce diverse lymphokines, whereas neonatal B cells are less responsive to the lymphokines that promote terminal differentiation to plasma cells.
Synthetic Peptides and Purified Antigens as Vaccines
Authors: Brown Fred
Published: October 2009

Molecular biology and, in particular, knowledge of the immune response at the molecular level provide the research community with the opportunity to design vaccines that will elicit the appropriate responses for many diseases. The critical issue is to identify the immune response that correlates with protection. It is remarkable how well the empirical approach has worked; it is essential, therefore, not to ignore the lessons to be learned from these successes. It is particularly essential that each disease and the immune response that affords protection be studied individually so that the appropriate responses can be induced.
Combination Vaccines
Authors: Ellis Ronald W. , Douglas R. Gordon
Published: October 2009

The availability of new vaccines for pediatric use provides an unprecedented opportunity to prevent serious infectious diseases and their associated morbidity and mortality. However, each new product entails the need for additional injections that could become so numerous as to discourage the administration of new vaccines. This challenge can be overcome by mixing individual vaccines before delivery such that multiple vaccines are administered as single combination vaccines. Technical, clinical, manufacturing, regulatory and marketing issues relative to combination vaccines in general are the major challenges for ongoing and future development.
Conclusion: A New Technologic Synthesis: The Children's Vaccine Initiative
Authors: Ramachandran Suryanarayan , Russell Philip K.
Published: October 2009

If the visionary goals of the Children's Vaccine Initiative (CVI) are to be achieved, it will have to be an initiating, integrating, and propelling force in the development, manufacturing, and use of vaccines. Success in solving the major technological challenges may depend first on solving the problem of incorporating the major players into the CVI. Today's relationship between private vaccine manufacturers and publicsector purchasers must give way to a new era of cooperation and coordination.
Problem solving methods and knowledge systems: A personal journey to perceptual images as knowledge
Authors: Chandrasekaran B.
Published: October 2009

I was among those who proposed problem solving methods (PSMs) in the late 1970s and early 1980s as a knowledge-level description of strategies useful in building knowledge-based systems. This paper summarizes the evolution of my ideas in the last two decades. I start with a review of the original ideas. From an artificial intelligence (AI) point of view, it is not PSMs as such, which are essentially high-level design strategies for computation, that are interesting, but PSMs associated with tasks that have a relation to AI and cognition. They are also interesting with respect to cognitive architecture proposals such as Soar and ACT-R: PSMs are observed regularities in the use of knowledge that an exclusive focus on the architecture level might miss, the latter providing no vocabulary to talk about these regularities. PSMs in the original conception are closely connected to a specific view of knowledge: symbolic expressions represented in a repository and retrieved as needed. I join critics of this view, and maintain with them that most often knowledge is not retrieved from a base as much as constructed as needed. This criticism, however, raises the question of what is in memory that is not knowledge as traditionally conceived in AI, but can support theconstructionof knowledge in predicate–symbolic form. My recent proposal about cognition and multimodality offers a possible answer. In this view, much of memory consists of perceptual and kinesthetic images, which can be recalled during deliberation and from which internal perception can generate linguistic–symbolic knowledge. For example, from a mental image of a configuration of objects, numerous sentences can be constructed describing spatial relations between the objects. My work on diagrammatic reasoning is an implemented example of how this might work. These internal perceptions on imagistic representations are a new kind of PSM.
Neurodevelopmental factors associated with schizotypal symptoms among adolescents at risk for schizophrenia
Authors: Hans Sydney L. , Auerbach Judith G. , Nuechterlein Keith H. , Asarnow Robert F. , Asarnow Joan , Styr Benedict , Marcus Joseph
Published: October 2009

Schizophrenia has come to be viewed as a neurodevelopmental disorder that is characterized by genetic vulnerability, stressors during the prenatal period that may be marked by minor physical anomalies and neurobehavioral deficits that emerge in early development. Less is known about the neurodevelopmental origins of schizotypal personality symptoms. The present study examines schizotypal symptoms in Israeli adolescents (mean age = 16.79 years) who have not yet reached the developmental period during which first schizophrenic episode is most likely to emerge: 39 adolescent offspring of parents with schizophrenia, 39 offspring of parents with other psychiatric disorders, and 36 offspring of parents with no history of mental illness. The Semi-Structured Kiddie Interview for Personality Syndromes was used to assess cognitive–perceptual, interpersonal, and disorganized schizotypal symptoms. Interpersonal schizotypal symptoms were more prevalent in the schizophrenia offspring group than in the no-mental-illness offspring group. Among the schizophrenia offspring group, interpersonal, but not cognitive–perceptual, schizotypal symptoms were associated with minor physical anomalies, fine motor dyscoordination, and deficits in executive functioning during adolescence. Among young people whose parents did not have schizophrenia, cognitive–perceptual schizotypal symptoms were correlated with deficits in executive functioning. Adolescent schizotypal symptoms were associated with neurobehavioral symptoms measured during middle childhood in a subgroup of the sample that had been assessed prospectively. Finally, young people who had genetic risk for schizophrenia, minor physical anomalies, and neurobehavioral signs together were at markedly increased risk for symptoms of interpersonal schizotypal symptoms, compared to young people with one or none of these risk factors.
What makes narcissists bloom? A framework for research on the etiology and development of narcissism
Authors: Thomaes Sander , Bushman Brad J. , Orobio de Castro Bram , Stegge Hedy
Published: October 2009

Narcissism is a dynamic form of personality characterized by a pervasive sense of grandiosity and self-importance, and by a need to obtain continuous self-validation from others. Very little is known about its etiology and development. What factors (e.g., temperament, parenting experiences) and processes (e.g., transactions between these factors over time) cause some children to become more narcissistic than others? When does narcissism first emerge, and how does narcissism develop over time? This article describes a framework for research on the etiology and development of narcissism, and recommends ten research priorities. This research should yield fundamental knowledge and should inform intervention efforts to minimize the negative impact narcissistic individuals have on themselves and on others.
A prospective investigation of the development of borderline personality symptoms
Authors: Carlson Elizabeth A. , Egeland Byron , Sroufe L. Alan
Published: October 2009

The antecedents and developmental course of borderline personality disorder symptoms were examined prospectively from infancy to adulthood using longitudinal data from a risk sample (N= 162). Borderline personality disorder symptom counts were derived from the Structured Clinical Interview forDSMDisorders diagnostic interview at age 28 years. Correlational analyses confirmed expected relations between borderline symptoms and contemporary adult disturbance (e.g., self-injurious behavior, dissociative symptoms, drug use, relational violence) as well as maltreatment history. Antecedent correlational and regression analyses revealed significant links between borderline symptoms in adulthood and endogenous (i.e., temperament) and environmental (e.g., attachment disorganization, parental hostility) history in early childhood and disturbance across domains of child functioning (e.g., attention, emotion, behavior, relationship, self-representation) in middle childhood/early adolescence. Process analyses revealed a significant mediating effect of self-representation on the relation between attachment disorganization on borderline symptoms. The findings are discussed within a developmental psychopathology framework in which disturbance in self-processes is constructed through successive transactions between the individual and environment.
Stability, change, and heritability of borderline personality disorder traits from adolescence to adulthood: A longitudinal twin study
Authors: Bornovalova Marina A. , Hicks Brian M. , Iacono William G. , McGue Matt
Published: October 2009

Although personality disorders are best understood in the context of lifetime development, there is a paucity of work examining their longitudinal trajectory. An understanding of the expected course and the genetic and environmental contributions to these disorders is necessary for a detailed understanding of risk processes that lead to their manifestation. The current study examined the longitudinal course and heritability of borderline personality disorder (BPD) over a period of 10 years starting in adolescence (age 14) and ending in adulthood (age 24). In doing so, we built on existing research by using a large community sample of adolescent female twins, a sensitive dimensional measure of BPD traits, an extended follow-up period, and a longitudinal twin design that allowed us to investigate the heritability of BPD traits at four discrete ages spanning midadolescence to early adulthood. Results indicated that mean-level BPD traits significantly decline from adolescence to adulthood, but rank order stability remained high. BPD traits were moderately heritable at all ages, with a slight trend for increased heritability from age 14 to age 24. A genetically informed latent growth curve model indicated that both the stability and change of BPD traits are highly influenced by genetic factors and modestly by nonshared environmental factors. Our results indicate that as is the case for other personality dimensions, trait BPD declines as individuals mature from adolescence to adulthood, and that this process is influenced in part by the same genetic factors that influence BPD trait stability.
Is there a Prehistory of Linguistics?
Authors: Renfrew Colin , Bynon Theodora , Ruhlen Merritt , Dolgopolsky Aron , Bellwood Peter
Published: October 2009

There are few aspects of human behaviour more fundamental than our ability to use language. Language plays a key role in the study of any living human society, and of all historical communities which have left us written records. In theory it could also throw enormous light on the development and relationships of prehistoric human communities. But here there is a huge and obvious problem: what evidence can there be for human languages in the pre-literate, prehistoric age? In other words, what hope is therefor a prehistory of linguistics? There is no easy answer, yet it is hard to accept that any account of human prehistory can be considered adequate without some knowledge of prehistoric languages and linguistic relationships, if only at the broadest scale.

The list of questions we might wish to pose stretches back to the period of the very earliest hominids. When did our human ancestors first begin to talk to each other? Was language acquisition sudden or gradual? Did human language arise in one place, and then spread and diversify from- that point? Or did it emerge independently, among separate groups of early humans in different parts of the world?

Leading on from this is the study of ethnicity and ethnogenesis. Since the end of the nineteenth century one of the biggest problems facing prehistoric archaeologists has been the identification and interpretation of archaeological cultures and cultural groups. Do these have any social or ethnic reality? Is it right to speak of a Beaker ‘folk’? Was the Bandkeramik colonization the work of one people or of many? These questions would be so much easier to resolve if only we could trace the prehistory of languages, and could establish, for instance, whether all Bandkeramik and Beaker users spoke the same or a related language.

Such possibilities may seem exciting and hopeful to some, irredeemably optimistic to others. Whatever view we take, they clearly merit serious discussion. In the present Viewpoint, our third in the series, we have asked five writers — two archaeologists (Renfrew & Bellwood), three linguists (Bynon, Ruhlen & Dolgopolsky) — to give their own, personal response to the key question ‘Is there a prehistory of linguistics?’ Can we, from the evidence of archaeology, linguistics (and now DNA studies), say anything positive about langtiage in prehistory?
Communication and Material Culture: Pleistocene Tools as Action Cues
Authors: Byers A. Martin
Published: October 2009

The gesture-call practices of early hominids were of a different order from those of their primate relatives, the ancestors of present day apes. The Tool-Cue Model postulates how our ancestors might have used tools both as functional instruments and as icons. The central thesis of the model treats communication as action systems mediated by signs, the central communicative action being the action cue: a communicative act that requires further behaviours to be satisfied. Tools are interpreted as framing devices, promoting the emergence of pragmatic/semantic duality. This latter feature is based on grammatical structures that include pragmatic and semantic meanings in the same utterance. Human language, i.e. symbolic pragmatics, appropriated the action cue meaning of tools and, simultaneously, transformed tools into symbolic ‘warrants’ by which modern humans transform both their speech and material behaviours into the types of social activities we intend. Post-Oldowan Lower and Middle Pleistocene lithics serve as empirical evidence in support of the Tool-Cue Model.
Food, Sex and Death: Cosmologies in the British Iron Age with Particular Reference to East Yorkshire
Authors: Pearson Mike Parker
Published: October 2009

The British Iron Age had an enduring set of traditions involving the east– west axis of the sun's path, the sunwise progression of movement and the classification of animals. Although these traditions were manifested regionally in slightly different ways and were modified, contested and restructured during the Iron Age, they provide us with a key to unlock aspects of the symbolism and practices of daily life. The significance of westerly orientations and of pigs in embodying and expressing associations of high status and other social differences were principal features of a strongly hierarchical society whose social differences were otherwise largely muted in terms of material culture distinctions. The cemeteries of East Yorkshire provide a detailed insight into the ordering of these social differences which were, even then, only rarely expressed through grave goods and mortuary elaboration. The burials of the Yorkshire elite are suggestive of a conception of sacred leadership or kingship, which included the symbolic spearing of certain individuals. Animal offerings were used in the structuring of social differences, with pig portions and sheep bones marking thedead of elite and commoner groups respectively.
Re-Reading the Landscape: Place and Identity in NE Australia During the Late Holocene
Authors: David Bruno , Wilson Meredith
Published: October 2009

Through an examination of land use during the late Holocene, this article explores the changing nature of place and identity in what is today Djungan country (NE Australia). We begin with the notion that use of place is mediated by historically positioned systems of meaning. We further contend that through praxis (as social practice), experience of place participates in the structuring and construction of identity. By examining changes in the way a distinctive mountain — Ngarrabullgan (Mt Midligan) — has been incorporated within the broader socio-cultural landscape through time, we conclude that major alterations took place in peoples’ relations to their surroundings, and by implication in the construction of landscapes, life experiences and identity, around the fourteenth century AD. This has implications for the way we project ethnographic details, attuned to Dreaming-based ontological views of the world, into the more distant past.
Figurines as Representations and Products at Paso de la Amada, Mexico
Authors: Lesure Richard
Published: October 2009

It is useful to view ceramic figurines from the Early Formative site of Paso de la Amada, Mexico, as both representations and products. That analysis links changes in a tradition of small, solid figurines to the rise of a novel social discourse concerning the elaboration and beautification of the human body. An increasing symbolic emphasis on the body may have been an important backdrop to the emergence of chiefly ideologies in the region.

The days are long gone when archaeologists would automatically interpret any major prehistoric monument as evidence of a hierarchically organized society. Faced with a Stonehenge or a Silbury Hill, the evident deployment of large labour forces might naturally lead to thoughts of social élites and stratified societies. The task facing archaeologists today, however, is to interpret such monuments not as programmatic products of parallel social processes but as elements in unique and dynamic configurations of social, political and ideological interactions. This is the approach which the present volume seeks to exemplify, taking as its focus the famous site of Cahokia in the Mississippi valley. Cahokia itself is the greatest monument complex of prehistoric North America, marked by 120 mounds spread over an area of 13 square kilometres across the Mississippi river from the modern city of St Louis. During the twelfth century AD this was a settlement with a population estimated to have numbered in the thousands if not tens of thousands. What does such a phenomenon represent in social and political terms?

In this book, Thomas Emerson considers not just the monuments of Cahokia themselves but the evidence for ideology and the power relationships which might have supported a hierarchical society, and the mechanisms which may have connected Cahokia with its rural hinterland. The wealth of detailed information available from the sites in and around Cahokia — some of them excavated by Emerson himself — allows a detailed analysis at a level which is rarely possible in archaeological cases of this kind. Drawing on concepts of individual agency, power and ideology as forces for social change, Emerson interprets the rise of Cahokia as the successful manipulation of ideology by élites, an ideology in which the subordinate layers of society are compelled to participate.

Emerson's study raises key questions about the rise and fall of complex societies, and the role of ideology and agency in that process. That these questions remain open to debate, the contributions to this review feature amply demonstrate. How hierarchical was Cahokia, how effective was élite ideology, and, above all, how can we go about analyzing this kind of question from the archaeological evidence? The results have a bearing on archaeological interpretation at the very broadest level.
Duplication of the right coronary artery in a patient with hypertrophic cardiomyopathy and myocardial bridging

Hypertrophic cardiomyopathy is a genetic myocardial disorder. In such patients, myocardial bridging is the most frequent encountered coronary arterial anomaly. Patients may, however, on occasion, present with other much rarer malformations of the coronary arteries. Duplication of the right coronary artery is a very rare anomaly. We have now encountered a patient with hypertrophic cardiomyopathy in whom we found myocardial bridging of the anterior interventricular coronary artery and duplication of the right coronary artery. To the best of our knowledge, this association has not previously been described.

Parents of children with congenitally malformed hearts can suffer from stress as a result of the medical condition of their child. In this cross-sectional study, we aimed to describe levels of parental stress, and perceived vulnerability, in parents of children who underwent major cardiac surgery, by using both generic and disease-related measures for assessment. We included parents of children who underwent open-heart surgery over the period 2002 through 2007 in the Center for congenital Anomalies Heart Amsterdam/Leiden, abbreviated to provide the acronym CAHAL. In total, we assessed 114 mothers and 82 fathers of 131 children, using the Pediatric Inventory for Parents, short form, General Health Questionnaire, Parental Stress Index-Short Form, State-Trait Anxiety Index and the Child Vulnerability Scale. Compared to the reference groups of the instruments used, parents of children with congenitally malformed hearts did not report higher generic nor disease-related stress scores, and parenting levels of stress were also comparable to reference groups. State anxiety levels, however, were higher in mothers of children with congenitally malformed hearts. Both fathers and mothers reported significantly higher rates of perceived vulnerability than did parents of healthy children. Risk factors for increased anxiety and perceived vulnerability were found in the number of surgical procedures, the time past since the last procedure, and ethnicity. Severity of the lesion did not influence parental levels of stress, but parents of children with hypoplastic left heart syndrome did report higher levels of stress than other parents. Psychosocial screening of parents of children with congenitally malformed hearts is important in order to provide appropriate counselling to those parents most in need.
Arctic sea ice velocity field: General circulation and turbulent‐like fluctuations

Using buoy trajectories of the IABP data set, we analyze the Arctic sea ice velocity field as the superposition of a mean field and fluctuations. We study how the mean field can be objectively defined, using appropriate spatial and temporal averaging scales depending on the season considered: 400 km and 5 months for winter (i.e., approximately all the polar winter duration), and 200 km and 2 months for summer (i.e., approximately all the polar summer duration). The mean velocity field shows a strong intra‐annual (between winter and the following summer) as well as interannual variability. The fluctuations, i.e., the remaining part of the velocity field after subtracting the mean field, are analyzed in terms of diffusion properties. Although the Arctic sea ice cover is a solid, we show that the fluctuations follow the same diffusion regimes as the ones predicted for turbulent flows, as observed in geophysical fluids like the ocean or the atmosphere. We found that the integral time and the diffusivity of sea ice are in the same ranges as those estimated for the ocean, i.e., 1.5 days in winter and 1.3 days in summer and 0.44 × 103 m2/s for winter and 0.45 × 103 m2/s in summer, respectively. However, the statistics of the sea ice fluctuating velocity deviate from classical turbulence theory, as they show exponential instead of Gaussian distributions. Sea ice velocity and acceleration are intermittent, and both are characterized by a multifractal scaling. The oceanic and atmospheric dynamic forcing cannot explain solely the statistical properties of sea ice kinematics and dynamics. We argue that sea ice dynamic is significantly influenced by the interplay of multiple fractures that are activated intermittently within the ice pack.
Deep mantle forces and the uplift of the Colorado Plateau

We introduce a quantitative model of global mantle convection that reconstructs the detailed motion of a warm mantle upwelling over the last 30 Ma towards the interior of the southwestern USA from observed present‐day mantle heterogeneity. The onset and evolution of uplift in the central Basin and Range province and Colorado Plateau during this time is determined by tracking the topographic swell due to this mantle upwelling. We show that: (1) the extension and basaltic volcanism (post 25 Ma) in the central Basin and Range coincides with the arrival and eastward progression of this upwelling, and (2) dynamic uplift of the southern Colorado Plateau, totaling about 1 km, transpired in the last 20 Ma. Since 10 Ma, the center of uplift continued northeastward from the southwestern rim of the plateau consistent with a young Grand Canyon model and eastward sweep of magmatism in the western Colorado Plateau.
