A computer assisted study of science education in Australian primary schoolsAllen, L. R., n/a January 1982 (has links)
It is a well documented fact that primary teachers as a group
are quite lacking in their enthusiasm for science, a subject
of constant concern for those committed to its role as a component
of the primary school curriculum.
In order to test the effects of various treatments on groups of
teachers and pre-service trainees, a 21 item questionnaire was
developed to measure attitudes towards science in the primary
school curriculum, towards improving expertise in the area, and
in the traditional "escientific attitudes and values"e.
A new group of pre-service students provided one group and the
pilot population, students in their final semester of a Diploma in
Teaching programme another group, and teachers attending residential
schools for UG2 conversion and PGl teacher education courses provided
several other groups based on teaching location.
Items were selected from the pilot instrument on their ability
to discriminate between high scoring and low scoring groups
measured with the Mann-Whitney U test.
Analyses in the main survey between groups, were carried out using
Mann-Whitney U test and Kruskal-Wallis one way analysis of variance,
and between items, using Wilcoxon matched-pairs signed-ranks test.
All manipulation and analysis of data was carried out with the
assistance of two computer programs, written in PASCAL by the
author specifically for this study � one for item analysis, the
other, a statistical package for analysing the main survey data.
Findings include 'support for prediction in the literature that
change in education is a slow process, demanding ongoing support
by the system and teacher education institutions, for teachers
committed to the change.
Also, the value of computer support, and advantages of tailoring
a statistical package to the study, rather than the study to
analyses readily accessible, are clearly demonstrated.

Developing a new transformatory cultural tourism experience model / Milena IvanovicIvanovic, Milena January 2014 (has links)
The research question addressed by this thesis is: To what degree the results of the statistical
analysis will corroborate the main theoretical assumptions of the proposed theoretical model of
new authentic transformatory cultural tourism experience as transmodern phenomenon of
equality of two Cartesian levels of reality, material (objective authenticity) and experiential
(constructive authenticity) in informing the intrapersonal existential authenticity as outcome
transformatory tourist experience.
The main reason for undertaking this study is to resolve the evident crisis of postmodern
authenticity discourse arising from a failure of postmodern theoretical framework to integrate
three social authenticity theories into a coherent authenticity discourse. The research design
adopted in the study is theory-testing theory-building paradigm which incorporates both
deductive and inductive logic and was applied in three successive phases. In the first phase the
new theoretical model of transformatory cultural tourism experience was proposed, underpinned
by transmodern flat ontology and philosophy of the Speculative Realism. In the second phase
the main theoretical assumptions of equal contribution of objective and constructive authenticity
as independent variables in informing the transformatory experience as dependent variable
were empirically tested by standard multiple regression analysis. In the last deductive phase the
results of all empirical tests were inferred onto initial theoretical assumptions of the original
model and new modified model of transformatory cultural tourism experience has been
proposed with an addition of two newly identified transmodern experiential constructs,
epistemological and ontological authenticity.
For a primary data collection the instrument was a self-administered questionnaire and the
sampling strategy was a non-probability sampling. The data was collected during the period 01st
and 18 April 2011 at two sites, Constitution Hill and Hector Peterson Memorial in Johannesburg.
The sample size from two sites was N=406. The scales of measurements were already
developed in the earlier questionnaire and the confirmatory factor analysis was used to confirm
the variables contained in each factor, namely objective and constructive authenticity as
independent variables and transformatory experience as the dependent variable. The results of
a standard multiple regression analysis confirmed the importance of the model as independent
variables explained 30.7% of the variances (R2=.307) in the model. An unexpected result was
that objective authenticity explained 34.5% of the variance in the model (β = .345) which is
significantly higher than 30.5% of variance explained by constructive authenticity (β = .305). The
results of standard multiple regression analysis confirmed the main theoretical assumption of
the model of equality of material and experiential levels of Cartesian duality in informing the new
transformatory experience regarded as a transmodern phenomenon. The standard, stepwise
and hierarchical multiple regression tests were further conducted to establish if any moderating
variables should be added into the original model containing two independent variables. The
tests included five demographic variables (gender, place of residence, connection with culture,
and two items of education (pre-tertiary education and Bachelors degree) and none of the
variables explained a level of variability which warranted their inclusion into the model.
Consequently, the results of the retests of the model did not change its initial conceptualisation.
Finally, the t-test and Mann-Whitney U tests identified a significant difference between the two
groups in the level of authenticity of their experience derived from two sites. A group having
stronger inclination for authenticity is identified as Cultural Creatives, who are known as the
forerunners of transmodernism.
Based on the results of all statistical tests the final model was modified to reflect the important
theoretical findings pertaining to two new types of transmodern authenticity. Epistemological
authenticity denotes combined effects of objective and constructive authenticity in feeding the
ontological authenticity of transformatory experience. The ontological authenticity is further
identified as a confirmation of authentic-self which is required by Cultural Creatives. With
proposition of new modified model the theory-testing theory-building research design came to its
conclusion.
The importance of research findings presented in this study lies not only in resolving the current
crises of authenticity discourse in tourism but in the proposed New theoretical and conceptual
model of transformatory cultural tourism experience underpinned by objective ·and constructive
authenticity which will open a whole new field in tourism research arising from new transmodern
experiential paradigm. / PhD (Tourism Management), North-West University, Potchefstroom Campus, 2014

Aplikace statistické analýzy řeči pacientů s Parkinsonovou nemocí / Application of statistical analysis of speech in patients with Parkinson's diseaseBijota, Jan January 2016 (has links)
This thesis deals with speech analysis of people who suffer from Parkinson’s disease. Purpose of this thesis is to obtain statistical sample of speech parameters which helps to determine if examined person is suffering from Parkinson’s disease. Statistical sample is based on hypokinetic dysarthria detection. For speech signal pre-processing DC-offset removal and pre-emphasis are used. The next step is to divide signal into frames. Phonation parameters, MFCC and PLP coefficients are used for characterization of framed speech signal. After parametrization the speech signal can be analyzed by statistical methods. For statistical analysis in this thesis Spearman’s and Pearson’s correlation coefficients, mutual information, Mann-Whitney U test and Student’s t-test are used. The thesis results are the groups of speech parameters for individual long czech vowels which are the best indicator of the difference between healthy person and patient suffering from Parkinson’s disease. These result can be helpful in medical diagnosis of a patient.

GRAVIDA KVINNORS INTAG AV KOSTTILLSKOTT : En kvantitativ studie med fokus på järn och probiotika / PREGNANT WOMEN´S INTAKE OF DIETARY SUPPLEMENT : A quantitative study focusing on iron and probioticsLange Bålman, Miriam January 2019 (has links)
Sammanfattning Bakgrund Vitamin- och mineralbrister hos gravida kvinnor kan leda till missfall och allvarliga störningar i barnets utveckling. Moderns tarmflora överförs med stor sannolikhet till barnet under förlossningen och kan därför innebära ett viktigt steg i utvecklingen av barnets tarmflora. En tänkbar lösning för att säkra ett adekvat intag kan vara konsumtion av kosttillskott och probiotika. I dagsläget finns osäkra uppgifter om hur många gravida kvinnor som intar tillskott. Syfte Att undersöka hur många gravida kvinnor i Västerbottens län som valde att inta kosttillskott, främst järn och probiotika, samt om det fanns en skillnad mellan olika faktorer och intag. Metod En kvantitativ tvärsnittsstudie där gravida kvinnor (n=1473) från Northpop-studien i Västerbottens län svarade på ett frågeformulär gällande intag av kosttillskott och faktorer som ålder, utbildning, kostregim etc. De statistiska tester som användes var Chi-2-test, oberoende t-test och Mann Whitney U-test. Materialet analyserades i SPSS. Signifikansnivån sattes till p<0,05. Resultat Majoriteten av deltagarna svarade att de intog kosttillskott. Faktorer som ökade intaget av kosttillskott hos gravida kvinnor var högre ålder (p=0,030) jämfört med lägre ålder, högre utbildningsnivå (p=0,006) jämfört med lägre utbildningsnivå och vegetarisk/vegansk kost (p=0,021) jämfört med blandkost. Femtiofem procent uppgav att de intog järntillskott. De faktorer som ökade intaget av järntillskott hos gravida kvinnor var vegetarisk/vegansk kost (p=0,001) jämfört med blandkost. Probiotika intogs av 2 procent. Ett högre intag av probiotika sågs hos personer boende i stadsområde (p=0,024) jämfört med övriga boenderegioner samt de som åt vegetarisk/vegansk kost (p=0,001) jämfört med blandkost. Slutsats Majoriteten av deltagarna intog någon typ av kosttillskott, hälften intog järntillskott och en liten andel intog probiotika. Lågutbildade, yngre, de som äter blandkost och bor utanför stadsområde verkar vara i riskgruppen för att inte inta kosttillskott. / Abstract Background Vitamin and mineral deficiencies in pregnant women can lead to miscarriage and serious disturbances in children’s development. The intestinal flora of the mother is most likely transmitted to the child during childbirth and may lay the foundation for the child's health. One possible solution to ensure an adequate intake may be the consumption of dietary supplements and probiotics. At present, there is insufficient data on supplement consumption among pregnant women. Objective The purpose of the study was to examine how many pregnant women in Västerbotten County chose to consume dietary supplements, mainly iron and probiotics, and whether there was a difference between different factors and intake. Method A quantitative cross-sectional study where pregnant women (n=1473) from the Northpop-study in Västerbotten County responded to a questionnaire regarding consumption of dietary supplements and factors such as age, education, diet etc. The material was analyzed in SPSS with Chi-2-test, independent T-Test and Mann-Whitney U-Test. Using significance level <0.05. Results The majority of participants, 90 percent, responded that they consumed dietary supplements. The factors that increased the intake of dietary supplements in pregnant women were higher age (p=0.030), higher education (p=0.006) and vegetarian/vegan diet (p=0.021). Iron was reported to be consumed by 804 people, 55 percent. The factors that increased the intake of iron supplement in pregnant women were vegetarian/vegan diet (p=0.001). Probiotics were consumed by 25 people, 2 percent. Living in urban areas (p=0.024) and eating vegetarian/vegan diet (p=0.002) increased consumption of probiotics. Conclusion The majority of participants chose to consume some type of dietary supplement, half of the participants consumed iron supplements and a small part consumed probiotics. It appears that pregnant women who are low educated, younger, eating an omnivorous diet and living outside urban areas are in the risk zone for not consuming dietary supplements. / Northpop
