Homosexual men (and lesbian men) in a heterosexual genre: three gangster films from Hong Kong.

Of the East Asian film genres that have captured the attention of film goers internationally, it should be of little surprise that martial and heroically masculine genres have been the most popular, for violent action translates well into any language. Although it has been no secret that male martiality often leaks into homoerotic desire (on the part of the audience, too), three Hong Kong films from 1998 have finally explicated the generic homosexuality that the action genre has been (defensively) ashamed to admit all along. However, rather than posit this textual homosexuality as transgressive, the generic forces under which these films operate rewrite their homosexualities, both gay and lesbian, into generic modes fashioned around regressive oppositions of gender, and not progressive liberations of sexuality.

Is integer arithmetic fundamental to mental processing?: the mind's secret arithmetic.

Unlike the ability to acquire our native language, we struggle to learn multiplication and division. It may then come as a surprise that the mental machinery for performing lightning-fast integer arithmetic calculations could be within us all even though it cannot be readily accessed, nor do we have any idea of its primary function. We are led to this provocative hypothesis by analysing the extraordinary skills of autistic savants. In our view such individuals have privileged access to lower levels of information not normally available through introspection.

Providing independent recreational activities to reduce stereotypic vocalizations in chronic schizophrenics.

We evaluated the effects of minimally supervised, independent recreational activities on stereotypic vocal behavior in two chronic schizophrenic patients. In baseline sessions, subjects were observed during unstructured free time in the psychiatric ward. In treatment sessions, therapists presented preferred recreational materials (magazines, models, and art projects), verbally prompted on-task behavior every 20 min, and, in one condition, administered contingent tokens. Independent recreational activities reduced medium-rate self-talk in one subject and high-rate mumbling in a second subject by 60%-70%. Results were the same with or without contingent tokens. Apparent self-maintaining characteristics of these vocal responses are discussed.

Protein structures and information extraction from biological texts: the PASTA system.

MOTIVATION: The rapid increase in volume of protein structure literature means useful information may be hidden or lost in the published literature and the process of finding relevant material, sometimes the rate-determining factor in new research, may be arduous and slow. RESULTS: We describe the Protein Active Site Template Acquisition (PASTA) system, which addresses these problems by performing automatic extraction of information relating to the roles of specific amino acid residues in protein molecules from online scientific articles and abstracts. Both the terminology recognition and extraction capabilities of the system have been extensively evaluated against manually annotated data and the results compare favourably with state-of-the-art results obtained in less challenging domains. PASTA is the first information extraction (IE) system developed for the protein structure domain and one of the most thoroughly evaluated IE system operating on biological scientific text to date. AVAILABILITY: PASTA makes its extraction results available via a browser-based front end: http://www.dcs.shef.ac.uk/nlp/pasta/. The evaluation resources (manually annotated corpora) are also available through the website: http://www.dcs.shef.ac.uk/nlp/pasta/results.html.

The revolution that wasn't: a new interpretation of the origin of modern human behavior.

Proponents of the model known as the "human revolution" claim that modern human behaviors arose suddenly, and nearly simultaneously, throughout the Old World ca. 40-50 ka. This fundamental behavioral shift is purported to signal a cognitive advance, a possible reorganization of the brain, and the origin of language. Because the earliest modern human fossils, Homo sapiens sensu stricto, are found in Africa and the adjacent region of the Levant at >100 ka, the "human revolution" model creates a time lag between the appearance of anatomical modernity and perceived behavioral modernity, and creates the impression that the earliest modern Africans were behaviorally primitive. This view of events stems from a profound Eurocentric bias and a failure to appreciate the depth and breadth of the African archaeological record. In fact, many of the components of the "human revolution" claimed to appear at 40-50 ka are found in the African Middle Stone Age tens of thousands of years earlier. These features include blade and microlithic technology, bone tools, increased geographic range, specialized hunting, the use of aquatic resources, long distance trade, systematic processing and use of pigment, and art and decoration. These items do not occur suddenly together as predicted by the "human revolution" model, but at sites that are widely separated in space and time. This suggests a gradual assembling of the package of modern human behaviors in Africa, and its later export to other regions of the Old World. The African Middle and early Late Pleistocene hominid fossil record is fairly continuous and in it can be recognized a number of probably distinct species that provide plausible ancestors for H. sapiens. The appearance of Middle Stone Age technology and the first signs of modern behavior coincide with the appearance of fossils that have been attributed to H. helmei, suggesting the behavior of H. helmei is distinct from that of earlier hominid species and quite similar to that of modern people. If on anatomical and behavioral grounds H. helmei is sunk into H. sapiens, the origin of our species is linked with the appearance of Middle Stone Age technology at 250-300 ka.

Historical origins of schizophrenia: two early madmen and their illness.

Schizophrenia is a serious mental illness with a remarkably short recorded history. Unlike depression and mania, which are recognizable in ancient texts, schizophrenia-like disorder appeared rather suddenly in the psychiatric literature of the early nineteenth century. This could mean that the illness is a recent disease that was largely unknown in earlier times. But perhaps schizophrenia existed, embedded and disguised within more general concepts of madness and within the arcane languages and cultures of remote times. Both possibilities present major challenges to historical and psychiatric scholarship. These challenges are explored in this paper by presenting two "new" cases of schizophrenia, one from the eighteenth and one from the fourteenth century. The cases suggest that the illness may have existed as early as the medieval period. However, establishing the population prevalence of schizophrenia in earlier times--and therefore resolving the permanence-recency debate--may not be a feasible enterprise.

Knowledge-based educational systems.

In knowledge-based educational systems, the key concept is that information and procedures are represented in the same data structure. These structures can search for each other in flexible and, consequently, very robust ways. At the Air Force Human Resources Laboratory (AFHRL), our researchers are building computer environments that know what they know, know how people can best use them, and know how to draw inferences about their state--self-referential electronic tutors. In September 1986, artificial intelligence researchers participated in AFHRL's Research Planning Forum for Intelligent Tutorial Systems (ITS). This essay reviews the state of the philosophy, art, and science of artificial intelligence (AI) approaches to education. Then it summarizes the research issues which were presented, discussed, and better defined in this Forum--namely the nature and representation of 1) expertise modules, 2) student diagnostic modules, 3) adaptive instructional and curriculum modules, 4) instructional environments, and 5) man-machine interfaces. Advances in artificial intelligence, cognitive science, and instructional discourse have provided a means for investigating human learning, for representing an individual's own "knowledge processing." Research and development in knowledge-based educational systems seems promising, not only for helping people learn how to perform complex tasks, but also for explicitly expressing how people learn to learn. Therefore, would it not be wise to establish a scientific legacy for the development of effective knowledge-based tutorial systems which is informed by the best studies of mind and meaning, language and thought, purpose and paradox?

An intelligent interactive system for delivering individualized information to patients.

This paper is a report on the first phase of a long-term, interdisciplinary project whose goal is to increase the overall effectiveness of physicians' time, and thus the quality of health care, by improving the information exchange between physicians and patients in clinical settings. We are focusing on patients with long-term and chronic conditions, initially on migraine patients, who require periodic interaction with their physicians for effective management of their condition. We are using medical informatics to focus on the information needs of patients, as well as of physicians, and to address problems of information exchange. This requires understanding patients' concerns to design an appropriate system, and using state-of-the-art artificial intelligence techniques to build an interactive explanation system. In contrast to many other knowledge-based systems, our system's design is based on empirical data on actual information needs. We used ethnographic techniques to observe explanations actually given in clinic settings, and to conduct interviews with migraine sufferers and physicians. Our system has an extensive knowledge base that contains both general medical terminology and specific knowledge about migraine, such as common trigger factors and symptoms of migraine, the common therapies, and the most common effects and side effects of those therapies. The system consists of two main components: (a) an interactive history-taking module that collects information from patients prior to each visit, builds a patient model, and summarizes the patients' status for their physicians; and (b) an intelligent explanation module that produces an interactive information sheet containing explanations in everyday language that are tailored to individual patients, and responds intelligently to follow-up questions about topics covered in the information sheet.

Multicentre research and the WISECARE experience. Workflow Information Systems for European Nursing Care.

The benefits of collaborative research are becoming recognized increasingly within the profession of nursing due to the associated increased likelihood of funding, variety of practice settings and increased access to resources that collaboration brings. While such benefits have made collaborative research one of the most desirable strategies for achieving the goals of research, the potential problems of language and communication, culturally sensitive instruments, access to subjects, availability of technology and lack of research resources have complicated collaborative international research initiatives. Review of the literature, although encouraging such initiatives, does little to provide information regarding the processes involved in multinational collaboration or the associated advantages and disadvantages to guide those embarking on such large scale, multinational, cross-cultural studies. The diverse meanings of collaboration within research initiatives further hamper this understanding. Positive definitions focus on aspects such as sharing expertise, making a valuable contribution to the research and ultimately shared ownership of the accomplishments of the research. One such research project led by nurses was the WISECARE project. WISECARE (Workflow Information Systems for European Nursing Care) was funded by the European Commission and aimed to improve cancer nursing practice and ultimately patient outcomes through the integration and utilization of state of the art information technology. Such a project was developed as a result of nursing's apparent invisibility within health care delivery and the problems experienced by nurses in articulating their worth within an increasingly cost-conscious health care system. Oncology care was selected as the domain for the project not only because this speciality of nursing already has an established network of nurses throughout Europe in the European Oncology Nursing Society (EONS) but also because the practice of cancer nursing encompasses all aspects of nursing care. This paper will address the advantages and disadvantages associated with collaboration, using the WISECARE project as an example.

Automatic term list generation for entity tagging.

MOTIVATION: Many entity taggers and information extraction systems make use of lists of terms of entities such as people, places, genes or chemicals. These lists have traditionally been constructed manually. We show that distributional clustering methods which group words based on the contexts that they appear in, including neighboring words and syntactic relations extracted using a shallow parser, can be used to aid in the construction of term lists. RESULTS: Experiments on learning lists of terms and using them as part of a gene tagger on a corpus of abstracts from the scientific literature show that our automatically generated term lists significantly boost the precision of a state-of-the-art CRF-based gene tagger to a degree that is competitive with using hand curated lists and boosts recall to a degree that surpasses that of the hand-curated lists. Our results also show that these distributional clustering methods do not generate lists as helpful as those generated by supervised techniques, but that they can be used to complement supervised techniques so as to obtain better performance.

Deception, catholicism, and hope: understanding problems in the communication of unfavorable prognoses in traditionally-catholic countries.

The doctor's use of deception in appropriate circumstances has commonly been considered a necessity of the medical art. Resistance to full and frank communication is typical of many traditionally Catholic countries, and particularly of Italy, a western country where Catholicism remains particularly influential. The Catholic teaching on truth and lies, and the problem of telling the truth to a severely ill patient is discussed. It is suggested that the contemporary Catholic model of gradually telling a terminal patient the truth, which looks reasonable and feasible in theory, is rarely followed in practice, as in the majority of cases the truth is not told tout court. Problems stem from the way in which medicine is currently practiced in Italy; from the synergism between Catholicism and the medical tradition's grounded paternalism; and from the ambiguity of the term 'hope'. Catholic ethics in fact recommends that the truth must be told without destroying hope, but the Catholic meaning of 'hope' is very different from its meaning in current language.

Evaluation of a classroom program of creative expression workshops for refugee and immigrant children.

OBJECTIVE: This evaluative study assessed the effect of a creative expression program designed to prevent emotional and behavioral problems and to enhance self-esteem in immigrant and refugee children attending multiethnic schools. METHOD: The 12-week program involved 138 children, aged 7 to 13, registered in both integration classes designed for immigrant children and regular classes at two elementary schools. Pretest and posttest data were collected from the children themselves and from their teacher. Teachers used Achenbach's Teacher's Report Form to assess the emotional and behavioral symptoms of their pupils whereas children self-reported their symptoms with the Dominic, a computerized questionnaire. Self-esteem was measured with the Piers-Harris Self-Concept Scale administered by interviewers to the children. RESULTS: At the end of the program, the children in the experimental groups reported lower mean levels of internalizing and externalizing symptoms and higher mean levels of feelings of popularity and satisfaction than the children in the control groups, when controlling for baseline data. In integration classes, the effect on self-esteem was especially notable in boys. The intervention's effect on internalizing and externalizing symptoms was not modified by gender, age or fluency in the mainstream language. CONCLUSION: The study provides some evidence that creative workshops in the classroom can have a beneficial effect on the self-esteem and symptomatology of immigrant and refugee children from various cultures and backgrounds. These quantitative results support previous qualitative analysis showing that the workshops participate in the reconstruction of a meaningful personal world while simultaneously strengthening the link of the child to the group. They also transform the teachers' perceptions of newcomers by placing an emphasis on their strength and their resilience, while not negating their vulnerabilities.

[Artistic dream reconstructions of the Wolf Man in the light of experimental findings].

The authors take the famous dream picture by the "wolf-man" as the starting-point for experimental research of their own and relate the one to the other. They see the significance of pictorial representations of dreams less in the supplementary information they convey about the "text" of dreams than in the fact that they give separate expression to motility-based "gesture-associated" memories and ideas. These need to be distinguished from "language-associated" memories as there are dissociated modes of encoding experience underlying verbal and pictorial representation. The splitting of these modes into different part-codes is an important component of repression. In addition, the pictorial representation of dreams enables the patient to re-associate part-codes and thus achieve a "deferred" reconstruction and complementation of significant experiences. In the authors view, pictorial representation is favorable to the discovery of repressed material; it is as yet however impossible to say exactly what relationship there is between verbalized and pictorial representation in the context of analysis.

Jung, the trickster writer, or what literary research can do for the clinician.

This paper aims to show how literary scholarship can contribute to clinical debates by offering different methods of reading and interpreting works by Jung. Firstly, as texts form much of the means by which Jungian ideas are transmitted and worked upon, literary research offers methods of examining the way we read for authority and orthodoxy. Secondly, it is invaluable to look at the way in which Jung actually wrote. Jung portrays a dynamic psyche in action in his writings. His works are not only about a creative archetypal psyche, they enact and perform this creativity in the way in which he uses words. The rich playfulness demonstrated in The Collected Works is an example of a writer as a mythmaker of the psyche, one who absorbs unconscious creative energies into his writing in ways that dissolve modernity's cultural boundaries of science and art. In addition, the aesthetic component in Jung's writing is not a decoration of his ideas. Rather, his 'literary' qualities are themselves forms of argument about the fragile state of modern subjectivity. Using his essays on 'Synchronicity', and the 'Trickster', the paper will show these works to be responses to three related crises that still face clinicians and scholars today: the problematic role of the hero myth as an individuation narrative, the nature of 'science', and the crisis of western modernity itself in desperate need of psychic healing. The paper will show that where writing on synchronicity aims to individuate science by adding a 'feminine' Eros to its Logos biases, the Trickster essay is designed to ameliorate modernity by providing frameworks to make visible marginal or excluded material. In these works Jung tries to rejuvenate the modern world by re-connecting traditional symbolic systems with the psyche through myth as a language of psychic relating.

Nearest neighbors by neighborhood counting.

Finding nearest neighbors is a general idea that underlies many artificial intelligence tasks, including machine learning, data mining, natural language understanding, and information retrieval. This idea is explicitly used in the k-nearest neighbors algorithm (kNN), a popular classification method. In this paper, this idea is adopted in the development of a general methodology, neighborhood counting, for devising similarity functions. We turn our focus from neighbors to neighborhoods, a region in the data space covering the data point in question. To measure the similarity between two data points, we consider all neighborhoods that cover both data points. We propose to use the number of such neighborhoods as a measure of similarity. Neighborhood can be defined for different types of data in different ways. Here, we consider one definition of neighborhood for multivariate data and derive a formula for such similarity, called neighborhood counting measure or NCM. NCM was tested experimentally in the framework of kNN. Experiments show that NCM is generally comparable to VDM and its variants, the state-of-the-art distance functions for multivariate data, and, at the same time, is consistently better for relatively large k values. Additionally, NCM consistently outperforms HEOM (a mixture of Euclidean and Hamming distances), the "standard" and most widely used distance function for multivariate data. NCM has a computational complexity in the same order as the standard Euclidean distance function and NCM is task independent and works for numerical and categorical data in a conceptually uniform way. The neighborhood counting methodology is proven sound for multivariate data experimentally. We hope it will work for other types of data.

A methodology and implementation for annotating digital images for context-appropriate use in an academic health care environment.

Use of digital medical images has become common over the last several years, coincident with the release of inexpensive, mega-pixel quality digital cameras and the transition to digital radiology operation by hospitals. One problem that clinicians, medical educators, and basic scientists encounter when handling images is the difficulty of using business and graphic arts commercial-off-the-shelf (COTS) software in multicontext authoring and interactive teaching environments. The authors investigated and developed software-supported methodologies to help clinicians, medical educators, and basic scientists become more efficient and effective in their digital imaging environments. The software that the authors developed provides the ability to annotate images based on a multispecialty methodology for annotation and visual knowledge representation. This annotation methodology is designed by consensus, with contributions from the authors and physicians, medical educators, and basic scientists in the Departments of Radiology, Neurobiology and Anatomy, Dermatology, and Ophthalmology at the University of Utah. The annotation methodology functions as a foundation for creating, using, reusing, and extending dynamic annotations in a context-appropriate, interactive digital environment. The annotation methodology supports the authoring process as well as output and presentation mechanisms. The annotation methodology is the foundation for a Windows implementation that allows annotated elements to be represented as structured eXtensible Markup Language and stored separate from the image(s).

Temperamental commonalities and differences in euthymic mood disorder patients, creative controls, and healthy controls.

OBJECTIVE: Understanding of mood disorders can be enhanced through assessment of temperamental traits. We explored temperamental commonalities and differences among euthymic bipolar (BP) and unipolar (MDD) mood disorder patients, creative discipline graduate student controls (CC), and healthy controls (HC). METHODS: Forty-nine BP, 25 MDD, 32 CC, and 47 HC completed self-report temperament/personality measures including: The Affective Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS-A); the Revised NEO Personality Inventory (NEO-PI-R); and the Temperament and Character Inventory (TCI). RESULTS: Euthymic BP, MDD, and CC, compared to HC, had significantly increased cyclothymia, dysthymia and irritability scores on TEMPS-A; increased neuroticism and decreased conscientiousness on NEO-PI-R; and increased harm avoidance and novelty seeking as well as decreased self-directedness on TCI. TEMPS-A cyclothymia scores were significantly higher in BP than in MDD. NEO-PI-R openness was increased in BP and CC, compared to HC, and in CC compared to MDD. TCI self-transcendence scores in BP were significantly higher than in MDD, CC, and HC. LIMITATIONS: Most of the subjects were not professional artists, and represented many fields; temperament might be different in different art fields. CONCLUSIONS: Euthymic BP, MDD, and CC compared to HC, had prominent temperamental commonalities. However, BP and CC had the additional commonality of increased openness compared to HC. BP had particularly high Cyclothymia scores that were significantly higher then those of MDD. The prominent BP-CC overlap suggests underlying neurobiological commonalities between people with mood disorders and individuals involved in creative disciplines, consistent with the notion of a temperamental contribution to enhanced creativity in individuals with bipolar disorders.

Balint reassessed: the doctor, his patient, and the illness: a reappraisal.

Psychoanalytical theories seek to explain human behaviour. I believe that they are not scientific, whereas it appears that Balint thought they were. I suggest instead that they are better regarded as myths and part of an artistic discipline. Whereas most of the problems brought by patients to general practitioners can be understood in scientific terms, others can be understood only in artistic terms.These two terms reflect fundamentally different kinds of problems, and different language must be used to discuss them. Neither the two sets of terms nor the two kinds of problem can be confused without giving rise to error. I argue that Michael Balint came to a false conclusion about the nature of the general practitioner's task, about the way the problems posed by his difficult patients may be identified, and about some of the training doctors should receive.Balint's main contribution remains. He showed us that scientific skills alone are not enough if we are to understand our patients fully. He also showed us how a descriptive science of human behaviour in the consulting room was possible.To these insights must be added new understanding. Popper (1963) has provided us with a clear line of demarcation between science and the rest of our knowledge. This idea suggests that general practitioners should reaffirm the importance to them of the intellectual discipline of science. If they wish their understanding and practice to be comprehensive they must also affirm the importance of the arts. What they must not do is to confuse one with the other.
