Perceptions of Early Childhood Development practitioners regarding professionalisationNcube, Gugulethu January 2017 (has links)
Utilising a case study design in the Gauteng Province of South Africa, this study explores the perceptions of ECD practitioners regarding the professionalisation of the ECD sector. With a purposive sample of fifteen ECD practitioners teaching children aged between birth and four years this study sought to find out what is exactly happening in the sector regarding the birth of the new qualification for ECD teachers in the South African education system; which attempts to standardise a B.Ed. curriculum for new teachers in the ECD sector. Adopting the Uncertainty Reduction Theory (URT) as a lens, the study revealed that the Government and the Non-Governmental Organisations (NGOs) were not giving adequate support to the sector while parents viewed ECD centres as places of play and sleep rather than educational. The study concludes that the ECD sector is indispensable for the South African Education system to perform on par with other world countries and recommends that everyone; not only government; should come to the party to fix this challenge of the education system. / Dissertation (MEd)--University of Pretoria, 2017. / Early Childhood Education / MEd / Unrestricted

Pandemic Partnering: COVID-19's Impact on College Students' Dating PracticesWanzer, Claire Victoria 28 June 2022 (has links)
This thesis seeks to explore if and how college students' dating practices have changed amid the COVID-19 pandemic. Through eight focus group interviews (n=51), participants discussed their dating practices, use of online dating platforms, and navigation of health and safety protocols. A thematic analysis was used to identify and define major themes from the focus groups. Findings revealed four themes in how college students define dating, which were relational investment, exclusivity labels, dating progression, and the role of hookup culture. When addressing how the pandemic has changed the way college students date, six themes were identified: importance of communication, technology as a tool, impact of family, violating safety norms, negative affect expression, and gaining perspective. This thesis extends academic research on how dating is defined and how uncertainty in the COVID-19 pandemic has impacted dating practices of college students at a large U.S. university in the mid-Atlantic region. / MACOM / This thesis explores the impacts of the COVID-19 pandemic on college students dating practices. It uses focus group interviews of undergraduate college students at a large university in the mid-Atlantic region of the United States. Participants discussed their definition of 'dating,' use of technology and dating apps, and navigation of health and safety practices during a dating climate characterized by high uncertainty. Findings revealed four themes in how college students define dating, which were relational investment, exclusivity labels, dating progression, and the role of hookup culture. When addressing how the pandemic has changed the way college students date, six themes were identified: importance of communication, technology as a tool, impact of family, violating safety norms, negative affect expression, and gaining perspective. These findings have implications in how we understand dating, especially during a global health crisis.

Wrongful Convictions as a Result of Public Defender Representation.Ross, Annie Elizabeth 18 December 2010 (has links)
Our criminal justice system works very hard to prevent criminals from harming other individuals; however, unfortunately mistakes happen. One wrongful conviction is one too many. There are multiple factors that can be assumed to be the cause of wrongful convictions. However, due to the lack of directly related research, the determents are not well established. The following research addresses wrongful convictions as a result of public defender representation. Through the process of theory construction, the research uses critical race theory and social disorganization theory to show the relationship between court appointed representation and wrongful convictions. A new theory is also established that is referred to as the partial load reduction theory. This theory establishes the relationship that exists between wrongful convictions and public defender representation and provides solutions as well as new avenues for future research.

Nature’s Impact on Mental and Physical Wellbeing : A study of the mental and physical health in Greek Immigrants to SwedenGiouvanaki, Asimina January 2021 (has links)
In the past Man coinhabited harmoniously with nature only to have the balance disturbed with the advent of the Industrial Revolution replacing the green habitat with urban concrete settlements Consequently, the characteristics of the contemporary city pose a set of serious threat to man’s physical and mental health. Crowdedness, lack of apt infrastructure, pollution, noise pollution and rise in temperature are all contributing factors to the Man’s demised health and detachment from previous amicable coexistence with nature. For the past 30 years, extensive research has been conducted studying the correlation between man and nature, and nature’s impact on man’s health. The theory of “Biophilia,” by Edward, O. Wilson, Rachel and Stephen Kaplan’s “Attention Restorative Theory,” and Roger Ulrich’s “Stress Reduction Theory,” have been innovating and contributing towards gaining more understanding of the importance of a green environment in man’s everyday life. As a corollary the above-mentioned theories gave rise to the following quantitative study conducted over a 4-month period, including 81 respondents, in Spring 2020, focusing on whether a natural green environment in Sweden had impacted the mental and physical health in Greek immigrants to Sweden. The findings suggest that comparing the respondents’ life in Greece and respectively in Sweden there was indeed an improvement in the mood and health of the sample groups taking into consideration: how healthy they are, how healthy they feel, how happy they feel in relation to work, time spent in Sweden, marital status and of course the parameters that focus on the part of the natural environment at home and in their neighbourhood in Sweden. There seem to have been a statistically significant improvement in their health compared to when they lived in Greece but there is insufficient evidence to support that some of the parameters examined are responsible for this. Happiness on the other hand seem to possess a statistical important role due to their marital status among others along with the green surrounding environment having an impact on their mental well-being but not their physical health. Therefore, a more sustainable green environment seems to have impacted the overall psychological and physical state of the respondents, but further extensive research is recommended to investigate in depths others factors i.e., psychosomatics, environmental psychology along with nature related theories and studies.

On operational properties of quantitative extensions of lambda-calculusAlberti, Michele 05 December 2014 (has links)
Cette thèse porte sur les propriétés opérationnelles de deux extensions quantitatives du λ-calcul pur : le λ-calcul algébrique et le λ-calcul probabiliste.Dans la première partie, nous étudions la théorie de la β-réduction dans le λ-calcul algébrique. Ce calcul permet la formation de combinaisons linéaires finies de λ-termes. Bien que le système obtenu jouisse de la propriété de Church-Rosser, la relation de réduction devient triviale en présence de coefficients négatifs, ce qui la rend impropre à définir une notion de forme normale. Nous proposons une solution qui permet la définition d'une relation d'équivalence sur les termes, partielle mais cohérente. Nous introduisons une variante de la β-réduction, restreinte aux termes canoniques, dont nous montrons qu'elle caractérise en partie la notion de forme normale précédemment établie, démontrant au passage un théorème de factorisation.Dans la seconde partie, nous étudions la bisimulation et l'équivalence contextuelle dans un λ-calcul muni d'un choix probabliste. Nous donnons une technique pour établir que la bisimilarité applicative probabiliste est une congruence. Bien que notre méthode soit adaptée de celle de Howe, certains points techniques sont assez différents, et s'appuient sur des propriétés non triviales de « désintrication » sur les ensembles de nombres réels. Nous démontrons finalement que, bien que la bisimilarité soit en général strictement plus fine que l'équivalence contextuelle, elles coïncident sur les λ-termes purs. L'égalité correspondante est celle induite par les arbres de Lévy-Longo, généralement considérés comme l'équivalence extensionnelle la plus fine pour les λ-termes en évaluation paresseuse. / In this thesis we deal with the operational behaviours of two quantitative extensions of pure λ-calculus, namely the algebraic λ-calculus and the probabilistic λ-calculus.In the first part, we study the β-reduction theory of the algebraic λ-calculus, a calculus allowing formal finite linear combinations of λ-terms to be expressed. Although the system enjoys the Church-Rosser property, reduction collapses in presence of negative coefficients. We exhibit a solution to the consequent loss of the notion of (unique) normal form, allowing the definition of a partial, but consistent, term equivalence. We then introduce a variant of β-reduction defined on canonical terms only, which we show partially characterises the previously established notion of normal form. In the process, we prove a factorisation theorem.In the second part, we study bisimulation and context equivalence in a λ-calculus endowed with a probabilistic choice. We show a technique for proving congruence of probabilistic applicative bisimilarity. While the technique follows Howe's method, some of the technicalities are quite different, relying on non-trivial "disentangling" properties for sets of real numbers. Finally we show that, while bisimilarity is in general strictly finer than context equivalence, coincidence between the two relations is achieved on pure λ-terms. The resulting equality is that induced by Lévy-Longo trees, generally accepted as the finest extensional equivalence on pure λ-terms under a lazy regime.

Grönstrukturens funktion och betydelse för studenternas återhämtning (under covid-19 restriktioner) / Green structure's function and importance for students' recovery (during Covid-19 restrictions)Ahmad, Doaa January 2020 (has links)
Tidigare forskning har visat att exponering för grön miljö tillhandahåller hälsofördelar. Dessa fördelar indikerar bland annat återhämtningseffekt av stress, trötthet och uppmärksamhetsutmattning, vilket är särskilt viktigt för universitetsstudenter. Därför syftade denna studie att undersöka om det finns en koppling mellan universitetsstudenters kontakt med grönstruktur i/nära studiemiljö och studenternas upplevelse av sin studiemiljö under covid-19 restriktionerna. Detta med hjälp av en dagbokundersökning som förstudie och telefonintervjuer. Analysverktyget bestod av teoretiska ramverk, Attention Restoration Theory (ART) och Stress Reduktion Theory (SRT). Resultat och analys har bekräftat Attention Restoration Theory (ART), där det uppges att gröna naturliga miljöer ger återhämtningseffekt och väcker uppmärksamhet efter en mental trötthet. Därtill bekräftade den även Stress Recovery Theory (SRT), där det uppges att gröna naturliga miljöer ger positiva effekt på stressminskning, -bearbetning och -återhämtning. Slutsatsen till denna undersökning är att grönstruktur har en stor betydelse för universitetsstudenterna, detta då alla väljer att vistas eller komma i kontakt med gröna naturen på ett eller annat sätt, till exempel gå en promenad i naturen eller åka till en stuga i skogen. Att naturen är en del av studenternas vardag verkar vara framför allt en omedveten upplevelse för de flesta och sker utan erkännande eller bearbetning av miljön. Dock framkommer det att processen kan vara medveten för vissa studenter. / Previous research has shown that exposure to the green environment provides health benefits. These benefits indicate among other things, recovery effect of stress, fatigue and attention-exhaustion, which is especially important for university students. Therefore, this study aimed to investigate whether there is a connection between university students' contact with the green structure in / near the study-environment and the students' experience of their study environment during the covid-19 restrictions. This with the help of a diary-survey as a pilot-study and telephone interviews. The analysis tool consisted of theoretical frameworks, Attention Restoration Theory (ART) and Stress Reduction Theory (SRT). Results and analysis have confirmed Attention Restoration Theory (ART), where it states that green natural environments have a recovery effect and attracts attention after a mental fatigue. In addition, it also confirmed the Stress Recovery Theory (SRT), which states that green natural environments have a positive effect on stress reduction, processing and recovery. The conclusion of this study is that green structure is of great importance to university students, as everyone chooses to reside or get in touch with green nature in one way or another, for example going for a walk in a green environment or staying in a cottage in the forest. That nature is a part of the students' everyday life seems to be above all an unconscious experience for most and takes place without recognition or processing of the environment. However, it appears that the process may be conscious for some students.
