Student nurse-educators’ at a nursing school in the Western Cape, perceptions of teacher identity from a personal knowledge perspective

Teacher identity is regarded as an important disposition when it comes to training wouldbe teachers, irrespective of the field of study. It is during the teaching practice experience that student nurse-educators transit from their preconceived identity as a student to accepting the teacher identity. It is expected that for student to acquire this identify they require profound knowledge in subject content, pedagogy and didactic knowledge, so as to perform their professions effectively. Although the focus of teaching is the student teachers, attention is sometimes focused more on the nursing facilitators rather than on the nursing student teachers who are becoming teachers. However, good nursing training should also take into consideration the perceptions of nurse student teachers on the teacher identity. This study sought to describe student nurse-educators’ perception of teacher identity with respect to the subject matter, pedagogy, and didactic expertise at a School of Nursing, University of the Western Cape. The quantitative research approach, using the descriptive design was employed to guide the study. Data was collected by means of a self-administered questionnaire using a five point Likert scale. A list of students in master’s education programme was utilised as the sampling frame. The sample included the Masters students in nursing education programme who have completed their theoretical courses and teaching practice. The Statistical Package for Social Science software (SPSS) version 22 was used in the analysis of the survey.
Formative exploration of students’ perception about Community Medicine teaching at Mahatma Gandhi Institute of Medical Sciences, Sewagram, India

Objective: The objectives of the present formative research were to explore the medical undergraduates’ study problems and their perceptions about various teaching approaches in currently practiced teaching curriculum of Community Medicine. Material and Methods: The present formative research was undertaken at Dr. Sushila Nayar School of Public Health incorporating Department of Community Medicine, Mahatma Gandhi Institute of Medical Sciences, Sewagram. The respondents were 17 (26.5%) conveniently selected final year exam appearing medical undergraduates from 2004 regular batch of 64 students. A triangulation of qualitative research methods like free listing, pile sort exercise and a Focus Group Discussion (FGD) were used. A two dimensional scaling and hierarchical cluster analysis was completed with the pile sort data. The data was analyzed by using software Anthropac 4.98. 1/X software. Results: The medical undergraduates could understand the topics like Integrated Management of Neonatal and Childhood (IMNCI), Primary Health Care (PHC), cold chain system for vaccines, immunization and health education, dietary survey and cluster survey method taught in the community based camp approaches. Students found it difficult to comprehend the core of subject from the scattered lecture series over a long teaching period, especially using lengthy over head projector/liquid crystal display presentations. The major problems encountered in studying the subject of Community Medicine were difficulty in understanding the concepts of biostatistics, confusions due to apparently similar text in National Health Programs and difficulty to recall disease statistics due to vast syllabus. Conclusions: Students perceived the community based camp approach of teaching as a best method to understand the subject, which is an integration of task oriented assignments, integration of social sciences within medical domain and active community involvement. Hence, the community based camp approach can be scaled up as a best Community Medicine teaching approach. The active learning methods could be used to improve the lectures and the clinics which should be more concentrated in final year of teaching
A system for evaluating the effect of keyboard design on force

The purpose of this study was to develop a system to determine the effectiveness of an alternative keyboard design which aimed to reduce fingertip force and awkward wrist postures. A prototype alphanumeric keyboard, adjustable in four ways, was developed for this study. Four measurements were chosen to determine the effectiveness of each keyboard configuration: fingertip impact force; wrist position; productivity; and comfort and ease of use. Fingertip force was measured using instrumented keys that had strain gauges located between the key cap and the key switch. Wrist position was measured using electronic goniometers attached to the forearms and hands of the test subjects. A computer program was developed to measure productivity, and a questionnaire based on the Borg rating scale was developed to measure comfort and ease of use. The system was tested to ensure its accuracy. Linearity, repeatability, strike position sensitivity, and natural frequency of the instrumented keycap assembly were assessed. Ou.
Modulation of the RNAi pathway by chemically modified siRNA molecules

Para dirigir el silenciamiento genico post-transcripcional, la maquinaria de RNAi explota la formacion de pares de bases entre la hebra guia cargado y el ARNm complementario. La proteina Ago2 (Argonauta 2) es la "maquina de cortar" del complejo RISC y dirige la rotura endonucleolitica solo cuando la hebra guia del siRNA esta completamente apareada con su homologa de ARN. Ago2 es capaz de incorporar una molecula de duplex de siRNA, desenrolla la doble helice y mantiene una hebra mientras se descarta la otra cadena. Ago2 cargada con la hebra guia se define "activa" y puede guiar multiples reacciones de escision contra los ARNm complementarios. El analisis estructural del proceso de ensamblaje de Ago2 ha llevado a la conclusion de que las primeras interacciones entre el siRNA y la proteina Ago2 se basa en el reconocimiento especifico por el dominio PAZ. Por lo tanto, el correcto reconocimiento de dominio PAZ contribuye a la incorporacion especifica y productiva de los siRNAs en el Ago2. La hebra guia con su extremo 3' protuberante que tiene 2-nt esta implicada en la mayoria de los contactos entre la cavidad presente en el dominio PAZ. En principio, las modificaciones en los extremos protuberantes se introdujeron para proteger la integridad del duplex de ARN. Solo despues de la comprension de la arquitectura de Ago2, se penso en la utilizacion de las modificaciones en los extremos protuberantes para mejorar la potencia y especificidad de los siRNAs. Para explorar las caracteristicas estructurales criticas para la interaccion entre la cavidad PAZ, modificamos los extremos protuberantes de los siRNA con varias modificaciones. Especificamente, 2 unidades de un beta-L-nucleosido como la L-timidina (imagen especular de la timidina), de 2'-desoxiribitol, de GNA (glycerol nucleic acids)- timina y del derivado aciclico L-treoninol se introdujeron a los extremos protuberantes y se midio la potencia de silenciamiento (IC50). Tales modificaciones pueden proporcionar pistas fundamentales sobre el requisito estructural necesario para el reconocimiento y carga de la cadena del dominio PAZ de Ago2.
Preliminary studies on the local names, prevailing beliefs and treatment practices of some common parasitic diseases in rural areas of Sokoto, Kebbi and Zamfara States, Nigeria

A study was conducted to determine the local names, prevailing local beliefs and treatment practices of some common parasitic disease in rural areas of Sokoto, Kebbi and Zamfara State. The identified common parasitic diseases were Malaria, Intestinal helminthiasis, schistosomiasis, Dracunculiasis, and Amoebic dysentery. The people have several names for each of the parasitic diseases. The use of plants extract is the most common treatment practices. The result revealed a general ignorance of the causes and treatment of the parasitic disease in the area. The implication of the findings to the global efforts of parasitic diseases control is discussed. The Nigerian Journal of Parasitology Vol. 24 2003: 103-108
A quest for selfhood : deconstructing and reconstructing female identity in Doris Lessing's early fiction

A prolific, anti-conformist, rebellious and provocative writer, Doris Lessing has been considered by critics as the forerunner of feminism, communism, anti-colonialism and anti-aparteid. By attributing to her the Nobel Price for Literature in 2007, the Swedish Academy rewarded an « epicist of the female experience, who, with skepticism, fire and visionary power subjected a divided civilization to scrutiny ». Reducing her work, however, to political issues means overlooking a crucial and omnipotent theme related to the quest for selfhood and the desire for self-knowledge animating the female subject, In order to gain this goal, it is first important to go through the experience of deconstruction. This is why this work will analyse Doris Lessing's deconstructive approach to the female identity. This deconstruction is not to be understood in the strict Derridian sense but in a broader persepective residing in the writer's universal and prophetic vision. In fact, Doris Lessing endeavors to deconstruct an essentialist conception which would lead to a universal apprehension of the female identity. She denies all logocentric thinking and questions fixed and unified identities, and by the same token, the universality of the quest. This reveals a nomadic thought, which in Deleuzian sense, entails that the female identity is fluid, changing, without frontiers, open to all possibilities and with a great potential to re-construct and re-define itself.

Ninety participants were equally divided into an experimental (n = 45) and a control group (n = 45). Both groups were instructed in dietary control and exercise, and received routine care at their respective antenatal clinics. The experimental group members also were trained in self-regulation skills. Instruments for data collection included the: a) Personal Information Questionnaire, and b) Daily Diet Control, Exercise and Two-hour Postprandial Blood Glucose Record Sheet. The Chi-square test revealed the rate at which the experimental group subjects controlled their diet, exercise and two-hour postprandial blood glucose levels, at weeks two, four and six of the program, to be significantly greater than in the control group. Moreover, relative risk analysis (risk ratio) showed the subjects, in the experimental group, could control their diet, exercise and two-hour postprandial blood glucose levels better than those in the control group at weeks two, four and six of the program. These findings illustrate the self-regulation program was effective in helping the experimental group subjects control their diets, exercise and blood glucose levels.

Weber-Christian Disease with Visceral Involvement

It is now recognized, as a result of absorption studies, that there is defective vitamin-Bu absorption after total gastrectomy and in many instances after partial gastrectomy. It is therefore important that the vitamin should be administered intramuscularly to certain patients after these operations have been performed. Similar remarks apply to patients with ulcerative colitis and certain types of ileitis. In view of the fact that large oral doses of vitamin B12 lead to appropriate absorption in the absence of intrinsic factor it is probably sufficient to administer massive dosage of the vitamin by mouth. This could apply to the treatment of pernicious anaemia, but remains to be proved by prolonged clinical trials. In any case, it is important to realize that patients who have developed megaloblastic anaemia as a result of defective absorption will have severe depletion of their vitamin-Bu stores. It is impossible to restore this to normal by intestinal absorption alone, and it is therefore important, in the first place, to give vitamin B1R in relatively large doses intramuscularly.
The NICHD Study of Early Child Care.

According to previous research, internalizing and externalizing problems tend to be comorbid or co-occur at different ages in development (Angold, Costello, & Erkanli, 1999). The question that this dissertation addresses is how and why internalizing and externalizing problems, two disorders that represent separate forms of psychopathology, co-occur in children. This is an important question for the developmental psychopathology perspective because an appreciation of the concept of co-occurrence is essential for explaining the development and taxonomy of internalizing and externalizing psychopathology, and for understanding the etiology and course of these symptoms (Achenbach, 1990). Attempts to explain co-occurrence have proposed that co-occurring psychopathology might represent distinct, meaningful syndromes (Angold & Costello, 1992; O’Connor et al., 1998), and in support of this idea, evidence of the existence of pure and co-occurring internalizing and externalizing problems has been found (Keiley et al., 2003). However, no previous study has identified heterogeneous developmental patterns of pure or combined internalizing and externalizing problems within a dynamic framework by taking trajectories of change into account. This dissertation uses data from the NICHD study of Early Child Care to explore the cooccurrence between internalizing and externalizing problems from age 2 to 12 with the use of Latent Class Growth Analysis. The sample included 1232 children (52% male). Different groups of children exhibiting low/normative, pure internalizing, pure externalizing, and co-occurring internalizing and externalizing problems across the 10 year period were identified. The higher risk groups deviated from the low/normative group in terms of antecedents, SES risk, medical risk, difficult temperament, and home environment. Moreover, children who exhibited pure moderate externalizing problems, and children who exhibited chronic externalizing problems, with and without co-occurring internalizing problems, engaged in more risky behaviors and were more likely to have friends who also engaged in risky behaviors. Furthermore, the pure chronic externalizing group and the groups scoring high on internalizing problems, with and without cooccurring externalizing problems, were more asocial with peers. Finally, children exhibiting chronic co-occurring externalizing and internalizing problems were more excluded by peers in comparison to the rest of the sample’s population.

Upbeat nystagmus as the initial clinical sign of Creutzfeldt–Jakob disease

one infratentorial lesion, as well as that of one juxtacortical lesion, if appropriate. In addition, a variety of different combinations exist between the most restrictive interpretation (A) and the most liberal one (C). We recently performed a study in which MRI evidence of spinal cord pathology was evaluated in a cohort of 104 patients, who had been newly diagnosed with MS. Here, we report additional analyses in which we applied interpretations A, B, and C to the data collected. If only the brain scan was analyzed, 79 patients fulfilled the criteria for dissemination in space. This number increased to 82 using the most restrictive interpretation (A), to 93 with interpretation B, and to 98 with the most liberal interpretation (C). These data show that application of spinal cord MR in this population increases the percentage that fulfils the criteria for MRI dissemination in space, varying from 79 to 94% depending on the interpretation applied. In conclusion, it is evident that the current implementation of MRI for the assessment of dissemination in space is ambiguous and not always based on scientific evidence. Specifically, the substitution of (missing) brain lesions by spinal cord MRI findings should be studied in a systematic (and prospective) fashion, both for their diagnostic accuracy and their interobserver reliability.
Analysis of acoustic correlates of British, Australian and American accents

This paper presents an analysis of the acoustic correlates of the differences of British, Australian and American English accents. The structures of the differences that characterise accents in speech can be divided into two parts: (a) phonetic differences; and (b) acoustic differences. The focus of this paper is on the analysis of acoustic correlates of accents including formants and their trajectories, pitch trajectory, pitch accent, pitch nucleus, duration and speaking rate. The acoustics of accents are modelled and estimated using 2D HMMs of formants and a model of pitch such as the rise/fall/connect (RFC) model. The differences between the accents are discussed. The Australian accent has a lower 1/sup st/ formant (F1) but higher 2/sup nd/ formant (F2) compared to British and American. The 2/sup nd/ formant in speech is considered as the most sensitive to accent identity. British speakers have the largest pitch frequency range and the largest initial pitch rise and final pitch fall rates in utterances. Australian accent exhibits significant elongation of vowels and the lowest speaking rate compared to other two accents. The differences in acoustic correlates across accents are used to morph the accent of a source speaker towards a target accent.
The importance of stop word removal on recall values in text categorization

Given a data set and a learning task such as classification, there are two prime motives for executing some kind of data set reduction. On one hand there is the possible algorithm performance improvement. On the other hand the decrease in the overall size of the data set can bring advantages in storage space used and time spent computing. Our purpose is to determine the importance of several basic reduction techniques on Support Vector Machines, by comparing their relative performance improvement when applied on the standard REUTERS-21578 benchmark.
Problems in doctor-patient communication: The case of younger women with breast cancer

Communication between physicians and patients is considered to be a core component in the provision and receipt of appropriate medical care. However, previous research indicates that doctor-patient relationships can be problematic, with negative consequences for patients including higher levels of anxiety, distrust of medical providers, dissatisfaction with healthcare and lower quality of life. This research utilizes data collected from a series of focus groups involving 19 women with breast cancer aged 50 and under to examine the nature of problems that may arise in communication between physicians and younger patients concerning the detection, diagnosis and treatment of this life-threatening disease. Conducted according to the general principals of grounded theory generation, this analysis identified four central themes: (1) women's realization of medical uncertainty, (2) their rejection of physician paternalism, (3) women's desire for information, and (4) their preference for a greater role in decision making. Qualitative data are presented in the context of social influences and cohort experiences that help to explain these difficulties. The results suggest that communication problems may be a consequence of incongruity between medical practice and patient expectations. Medical uncertainty regarding breast cancer in pre-menopause can lead to recognition of physician fallibility and rejection of expert authority. Socialized in an era of increasing patient autonomy and medical consumerism, results indicate that this cohort of women tends to prefer an active partner to passive patient role in the diagnostic and treatment decision-making process.
Possible Statistics of Two Coupled Random Fields: Application to Passive Scalar

We use the relativity postulate of scale invariance to derive the similarity transformations between two coupled scale-invariant random elds at different scales. We nd the equations leading to the scaling exponents. This formulation is applied to the case of passive scalars advected i) by a random Gaussian velocity field; and ii) by a turbulent velocity field. In the Gaussian case, we show that the passive scalar increments follow a log-Levy distribution generalizing Kraichnan's solution and, in an appropriate limit, a log-normal distribution. In the turbulent case, we show that when the velocity increments follow a log-Poisson statistics, the passive scalar increments follow a statistics close to log-Poisson. This result explains the experimental observations of Ruiz et al. about the temperature increments.
