Comparative Difficulties with Non-Scientific General Vocabulary and Scientific/Medical Terminology in English as a Second Language (ESL) Medical Students

Objectives: Medical education requires student comprehension of both technical (scientific/medical) and non-technical (general) vocabulary. Our experience with “English as a second language” (ESL) Arab students suggested they often have problems comprehending scientific statements because of weaknesses in their understanding of non-scientific vocabulary. This study aimed to determine whether ESL students have difficulties with general vocabulary that could hinder their understanding of scientific/medical texts. Methods: A survey containing English text was given to ESL students in the premedical years of an English-medium medical school in an Arabic country. The survey consisted of sample questions from the Medical College Admission Test (USA). Students were instructed to identify all unknown words in the text. Results: ESL students commenced premedical studies with substantial deficiencies in English vocabulary. Students from English-medium secondary schools had a selective deficiency in scientific/medical terminology which disappeared with time. Students from Arabic-medium secondary schools had equal difficulty with general and scientific/medical vocabulary. Deficiencies in both areas diminished with time but remained even after three years of English-medium higher education. Conclusion: Typically, when teaching technical subjects to ESL students, attention is focused on subject-unique vocabulary and associated modifiers. This study highlights that ESL students also face difficulties with the general vocabulary used to construct statements employing technical words. Such students would benefit from increases in general vocabulary knowledge

Towards Avatars with Artificial Minds: Role of Semantic Memory

he first step towards creating avatars with human-like artificial minds is to give them human-like memory structures with an access to general knowledge about the world. This type of knowledge is stored in semantic memory. Although many approaches to modeling of semantic memories have been proposed they are not very useful in real life applications because they lack knowledge comparable to the common sense that humans have, and they cannot be implemented in a computationally efficient way. The most drastic simplification of semantic memory leading to the simplest knowledge representation that is sufficient for many applications is based on the Concept Description Vectors (CDVs) that store, for each concept, an information whether a given property is applicable to this concept or not. Unfortunately even such simple information about real objects or concepts is not available. Experiments with automatic creation of concept description vectors from various sources, including ontologies, dictionaries, encyclopedias and unstructured text sources are described. Haptek-based talking head that has an access to this memory has been created as an example of a humanized interface (HIT) that can interact with web pages and exchange information in a natural way. A few examples of applications of an avatar with semantic memory are given, including the twenty questions game and automatic creation of word puzzles

Is race medically relevant? A qualitative study of physicians' attitudes about the role of race in treatment decision-making

<p>Abstract</p> <p>Background</p> <p>The role of patient race in medical decision-making is heavily debated. While some evidence suggests that patient race can be used by physicians to predict disease risk and determine drug therapy, other studies document bias and stereotyping by physicians based on patient race. It is critical, then, to explore physicians' attitudes regarding the medical relevance of patient race.</p> <p>Methods</p> <p>We conducted a qualitative study in the United States using ten focus groups of physicians stratified by self-identified race (black or white) and led by race-concordant moderators. Physicians were presented with a medical vignette about a patient (whose race was unknown) with Type 2 diabetes and untreated hypertension, who was also a current smoker. Participants were first asked to discuss what medical information they would need to treat the patient. Then physicians were asked to explicitly discuss the importance of race to the hypothetical patient's treatment. To identify common themes, codes, key words and physician demographics were compiled into a comprehensive table that allowed for examination of similarities and differences by physician race. Common themes were identified using the software package NVivo (QSR International, v7).</p> <p>Results</p> <p>Forty self-identified black and 50 self-identified white physicians participated in the study. All physicians - regardless of their own race - believed that medical history, family history, and weight were important for making treatment decisions for the patient. However, black and white physicians reported differences in their views about the relevance of race. Several black physicians indicated that patient race is a central factor for choosing treatment options such as aggressive therapies, patient medication and understanding disease risk. Moreover, many black physicians considered patient race important to understand the patient's views, such as alternative medicine preferences and cultural beliefs about illness. However, few white physicians explicitly indicated that the patient's race was important over-and-above medical history. Instead, white physicians reported that the patient should be treated aggressively regardless of race.</p> <p>Conclusions</p> <p>This investigation adds to our understanding about how physicians in the United States consider race when treating patients, and sheds light on issues physicians face when deciding the importance of race in medical decision-making.</p

Passivity, being-with and being-there: care during birth

This paper examines how to best be with women during birth, based on a phenomenological description of the birth experience. The first part of the paper establishes birth as an uncanny experience, that is, an experience that is not only entirely unfamiliar, but even unimaginable. The way in which birth happens under unknowable circumstances (in terms of when, how, with whom…) creates a set of anxieties on top of the fundamental anxiety that emerges from the existential paradox by which it does not seem possible for a body to give birth to another body. Would homebirth provide a remedy to the uncanniness? The result yielded by medical studies is confirmed by the phenomenological perspective taken here: homebirth might be reassuring for some, but not for everybody; choice of birth place is important. Once the birth process starts happening, another layer of strangeness is added: it turns out to be an experience of radical passivity and waiting, normally. The question thus becomes how to best care for somebody who is exposed to uncanniness, passivity, and waiting. Martin Heidegger’s concepts of care and discourse prove useful in examining how to facilitate rather than interrupt this process. It becomes necessary to think beyond verbal communication towards a wider concept of communication that involves silence and intercorporeality. Birth requires a special kind of being-with as being-there

A contagious living fluid: objectification and assemblage in the history of virology

This article deals with the birth of `the virus' as an object of technoscientific analysis. The aim is to discuss the process of objectification of pathogen virulence in virological and medical discourses. Through a short excursion into the history of modern virology, it will be argued that far from being a matter of fact, pathogen virulence had to be `produced', for example in petri-dishes, test-kits and hyper-real signification-practices. The now commonly accepted objective status of `the virus' has been an accomplishment of a complex ensemble of actors. Indeed, this illustrates why objectification rather than objectivity has become the main focus of science and technology studies. The objectification of `the' virus was by no means a smooth process. It involved more than five decades of highly speculative and fragmented research projects before it became actualized as a separate discipline under the heading of virology. The specific objectification of viruses took place through an inter-disciplinary de-differentiation of research questions, methodologies, techniques and technologies. The main argument of this article is that viruses only became intelligible after the establishment of a virology-assemblage. Its inauguration in the early 1950s was radical and sudden because only then could the various substrands of virological technoscience affect each other through deliberate enrolment, and engender a universal intelligibility

The "unknown territory" of goal-setting: Negotiating a novel interactional activity within primary care doctor-patient consultations for patients with multiple chronic conditions.

Goal-setting is widely recommended for supporting patients with multiple long-term conditions. It involves a proactive approach to a clinical consultation, requiring doctors and patients to work together to identify patient’s priorities, values and desired outcomes as a basis for setting goals for the patient to work towards. Importantly it comprises a set of activities that, for many doctors and patients, represents a distinct departure from a conventional consultation, including goal elicitation, goal-setting and action planning. This indicates that goal-setting is an uncertain interactional space subject to inequalities in understanding and expectations about what type of conversation is taking place, the roles of patient and doctor, and how patient priorities may be configured as goals. Analysing such spaces therefore has the potential for revealing how the principles of goal-setting are realised in practice. In this paper, we draw on Goffman’s concept of ‘frames’ to present an examination of how doctors’ and patients’ sense making of goal-setting was consequential for the interactions that followed. Informed by Interactional Sociolinguistics, we used conversation analysis methods to analyse 22 video-recorded goal-setting consultations with patients with multiple long-term conditions. Data were collected between 2016 and 2018 in three UK general practices as part of a feasibility study. We analysed verbal and non-verbal actions for evidence of GP and patient framings of consultation activities and how this was consequential for setting goals. We identified three interactional patterns: GPs checking and reframing patients’ understanding of the goal-setting consultation, GPs actively aligning with patients’ framing of their goal, and patients passively and actively resisting GP framing of the patient goals. These reframing practices provided “telling cases” of goal-setting interactions, where doctors and patients need to negotiate each other’s perspectives but also conflicting discourses of patient-centredness, population-based evidence for treating different chronic illnesses and conventional doctor-patient relations

Street slang and schizophrenia

We report the case of a 26 year old streetwise young postman who presented with a six month history of reduced occupational and social function, low mood, and lack of motivation. He complained of feeling less sociable and less interested in his friends and of being clumsy and finding it harder to think. He was otherwise fit and healthy, with no physical abnormalities, neurological signs, or objective cognitive impairments. There was no history of a recent stressor that might have precipitated his symptoms. He was referred to a specialist service for patients in the prodromal phase of psychotic illness for further assessment after he had seen his general practitioner and the local community mental health team. The differential diagnosis at this stage was depression, the prodrome of schizophrenia, or no formal clinical disorder. His premorbid occupational and social function had been good. There was no history of abnormal . social, language, and motor development and he left school with two A levels. After three years of service at the post office he had been promoted to a supervisory role. He had a good relationship with his family and had six or so good friends. There has been a number of previous heterosexual relationships, although none in the past year. Aside from smoking cannabis on two occasions when he was 19, there was no history of illicit substance use. Detailed and repeated assessment of his mental state found a normal affect, no delusions, hallucinations, or catatonia, and no cognitive dysfunction. His speech, however, was peppered with what seemed (to his middle class and older psychiatrist) to be an unusual use of words, although he said they were street slang (table).Go It was thus unclear whether he was displaying subtle signs of formal thought disorder (manifest as disorganised speech, including the use of unusual words or phrases, and neologisms) or using a "street" argot. This was a crucial diagnostic distinction as thought disorder is a feature of psychotic illnesses and can indicate a diagnosis of schizophrenia. We sought to verify his explanations using an online dictionary of slang (urbandictionary.com). To our surprise, many of the words he used were listed and the definitions accorded with those he gave (see table). We further investigated whether his speech showed evidence of thought disorder by examining recordings of his speech as he described a series of ambiguous pictures from the thematic apperception test, a procedure that elicits thought disordered speech. His speech was transcribed and rated with the thought and language index, a standardised scale for assessing thought disorder. Slang used in a linguistically appropriate way is not scored as abnormal on this scale. His score was 5.25, primarily reflecting a mild loosening of associations. For example, he described a picture of a boat on a lake thus: "There’s a boat and a tree. There seems to be a reflection. There are no beds, and I wonder why there are no beds. There’s a breeze going through the branches of the tree." His score was outside the normal range (mean for normal controls 0.88, SD 1.15) and indicates subtle thought disorder, equivalent to that evident in remitted patients with schizophrenia (mean in remitted patients 3.89, SD 2.56) but lower than that in patients with formal thought disorder (mean 27.4, SD 8.3). Over the following year his social and occupational functioning deteriorated further, and he developed frank formal thought disorder as well as grandiose and persecutory delusions to the extent that he met DSM-IV criteria for schizophrenia. His speech was assessed as before, and the thought and language index score had increased to 11.75. This mainly reflected abnormalities on items comprising "positive" thought disorder, particularly the use of neologisms such as "chronocolising" and non-sequiturs. To our knowledge this is the first case report to describe difficulties in distinguishing "street" argots from formal thought disorder. It is perhaps not surprising that slang can complicate the assessment of disorganised speech as psychotic illnesses usually develop in young adults, whereas the assessing clinician is often from an older generation (and different sociocultural background) less familiar with contemporary urban slang. Online resources offer a means of distinguishing street argot from neologisms or a peculiar use of words, and linguistic rating scales may be a useful adjunct to clinical assessment when thought disorder is subtle. Differentiating thought disorder from slang can be especially difficult in the context of "prodromal" signs of psychosis, when speech abnormalities, if present, are usually subtle. Nevertheless, accurate speech assessment is important as subtle thought disorder can, as in this case, predate the subsequent onset of schizophrenia, and early detection and treatment of psychosis might be associated with a better long term clinical outcome

Application of Qualitative Methods in Health Research: An Overview

Qualitative research is type of formative research that includes specialized techniques for obtaining in-depth responses about what people think and how they feel. It is seen as the research that seeks answer to the questions in the real world. Qualitative researchers gather what they see, hear, read from people and places, from events and activities, with the purpose to learn about the community and to generate new understanding that can be used by the social world. Qualitative research have often been conducted to answer the question “why” rather than “what”. A purpose of qualitative research is the construction of new understanding. Here, we present an overview of application of qualitative methods in health research. We have discussed here the different types of qualitative methods and how we and others have used them in different settings/scenarios; sample size and sampling techniques; analysis of qualitative data; validity in qualitative research; and ethical issues
