The aim of the study is to examine professional social workers experiences of legitimacy in conducting social work in Ghana’s capital Accra and to discuss possible sources of legitimacy. The idea is to problematize social work as a profession developed and constructed in Western contexts and exported to Ghana during the British colonization. The issue of legitimacy is examined from Ghanaian professional social workers subjective experiences of their meetings with clients and traditional authorities that historically been conducting social work in Ghana. The study is structured around three broad themes intending to explore the Ghanaian social workers experienced legitimacy as professionals in different sequences of the social work; the social workers experiences of legitimacy to (1) classify social problems, (2) to reason about social problems and (3) to take action on social problems. These themes are also basis for the fourth theme that provides a more explanatory discussion of the social workers experiences; (4) possible sources of legitimacy. The analysis conclude that the social workers experiences of legitimacy differ between whether the social work is conducted on an individual level or a community level, towards nuclear families or extended families and whether it is conducted in a social domain or institution that historically and traditionally been in the jurisdiction of traditional authorities or if it is a domain or institution that is recently introduced in the Ghanaian contexts due to modernization.

Detta är en kvalitativ studie, och syftet är att undersöka och få en djupare förståelse för Kinas skolsystem. Resultat från internationella jämförande studier, exempelvis PISA-undersökningen och TIMSS-studien, visar att kinesiska studenter har de högsta matematiska poängen. Detta väckte vårt intresse och ledde till början av denna studie. Forskningsmaterialet kommer från observationer vid tre skolor och intervjuer med aktiva lärare, blivande lärare och en rektor i Hohhot, Kina. Resultaten och slutsatsen av denna studie visar att innehållet i den kinesiska läroplanen är omfattande och ger inte mycket tid att individualisera lektionerna. Det kinesiska skolsystemet är mycket provorienterat, och tillsammans med pressen från samhället och deras föräldrar, är eleverna tvungna att tillbringa en hel del tid att studera.En annan slutsats till denna studie är att blivande lärare i Kina inte har mycket praktik på skolor, men de studerar en hel del matematik och metodik vid universitetet. / This is a qualitative study, and the purpose is to examine and gain a deeper understanding of China’s school system. Results from international comparative studies, such as the PISA survey and the TIMSS study, show that Chinese students have the highest mathematical scores. This evoked our interest and led to the beginning of this study. The research material comes from observations at three schools and interviews with in-service teachers, pre-service teachers and a head teacher in Hohhot, China. The results and the conclusion of this study shows that the content in the Chinese curriculum is comprehensive and does not give much time to individualize the lessons. The Chinese school system is very exam-oriented, and together with the pressure from the society and their parents, the students are forced to spend a lot of time to study. Another conclusion to this study is that pre-service teachers in China do not have much teacher practice at schools, but they study a lot of mathematics and methodology separately at the university.

The combination of water and surface active compounds found naturally in commercially refined vegetable oils have been postulated to form physical structures known as association colloids. This research studied the ability of 1,2-dioleoyl-sn-glycerol-3-phosphocholine (DOPC) and water to form physical structures in stripped soybean oil. Interfacial tension and fluorescence spectrometry results showed the critical micelle concentration (CMC) of DOPC in stripped soybean oil was 650 and 950 microM, respectively. Light scattering attenuation results indicated that the structure formed by DOPC was reverse micelles. The physical properties of DOPC reverse micelles were determined using small-angle X-ray scattering (SAXS) and fluorescence probes. These studies showed that increasing the water concentration altered the size and shape of the reverse micelles formed by DOPC. The impact of DOPC reverse micelles on the lipid oxidation of stripped soybean oil was investigated by following the formation of primary and secondary lipid oxidation products. DOPC reverse micelles had a prooxidant effect, shortening the oxidation lag phase of SSO at 55 °C. It also was not able to change the lipid oxidation of stripped soybean oil compared with DOPC reverse micelles at same concemtration ( i.e., 950 microM). 1,2-dibutyl-sn-glycerol-3-phosphocholine (DC4PC) which has the shorter fatty acid than DOPC was not able to form association colloids and did not impact lipid oxidation rates. This indicated that the choline group of the phospholipid was not responsible for the increased oxidation rates and suggested that the physical structure formed by DOPC was responsible for the prooxidant effect. The impact of the DOPC reverse micelles on the effectiveness and physical location of the antioxidants, alpha-tocopherol and Trolox was also studied. Both non-polar (alpha-tocopherol) and polar (Trolox) were able to inhibit lipid oxidation in stripped soybean oil in the presence of DOPC reverse micelles. Trolox was a more effective antioxidant than alpha-tocopherol. Fluorescence steady state and lifetime decay studies suggested that both alpha-tocopherol and Trolox were associated with DOPC reverse micelle in bulk oil. Trolox primarily concentrated in the water pool of reverse micelle since it quenched NBD-PE fluorescence intensity with increasing concentrations. A portion of alpha-tocopherol was also associated with the aqueous phase of the DOPC reverse micelles but this was likely at the oil-water interface since alpha-tocopherol is not water soluble. The addition of ferric chelator, deferoxamine (DFO) to stripped soybean oil significantly prevented the lipid oxidation caused by DOPC reverse micelles as the lag phase was extended from 2 to 7 days. DFO was also found to increase the antioxidant activity of both Trolox and alpha-tocopherol. Trolox and alpha-tocopherol were found to be rapidly decomposed by high-valence Fe(III) while low-valence-state (Fe (II) was much less reactive. Fe(III) was also consumed by both hydrophilic Trolox and lipophilic alpha-tocopherol presumably though reduction to Fe (II). DOPC reverse micelles were able to decrease antioxidants-iron interactions as evidence by a decrease in antioxidant depletion by iron and a decrease in iron reduction by the antioxidants. These results suggested that the ability of DFO to increase the antioxidant activity of alpha-tocopherol and Trolox was due to its ability to decrease free radical production and not its ability to decrease direct iron-antioxidant interactions. Overall, the results presented in this dissertation show phospholipids and water can form reverse micelles in edible oils. These reverse micelles increase lipid oxidation rates by increasing the prooxidant activity of iron. Free radical scavenging antioxidants can inhibit oxidation promoted by the reverse micelles with polar Trolox being more effective than non-polar alpha-tocopherol presumably because Trolox is more highly associated with the reverse micelle. The reverse micelles produced by DOPC protected alpha-tocopherol and Trolox from direct degradation by iron. The knowledge gained from this study will improve our understanding of the mechanism of lipid oxidation in bulk oils which will hopefully provide new technologies to improve the oxidation stability of edible oils. For example, it may be able to use oil refining technologies to remove prooxidative minor components that for physical structure in bulk oils.

<p> A textural and mineralogical study of the magnetite, hemoilmenite and minor sulfide phases of the Whitestone anorthosite, Dunchurch, Ontario, was carried out. The composition of magnetite and hemo-ilmenite was determined by chemical analysis, X-ray diffraction and electron probe microanalysis. A modification of the solvus shape in the hematite-ilmenite system consistent with the composition of hemo-ilmenite lamellae, as well as a mechanism for formation of metamorphic magnetite porphyroblasts from ferrianilmenite is proposed. Buddington and Lindsley's experimental data cannot be used directly to obtain f02 and T of formation of the anorthosite because compositions fall in the highly oxidizing and as yet undetermined portion of their diagram. </p> / Thesis / Master of Science (MSc)

In this thesis one can see footwashing from different perspectives even though the focus is from a liturgical and patristic perspective. Using the liturgical dialectical method, I put the liturgical text in a dialectical relationship with the wider patristic context. Footwashing in this thesis is approached from four angles. Chapter Two: An historical overview and a background regarding. Chapter Three: The Syriac Orthodox Footwashing rite. Chapter Four:The Commentary of Bar Salibi on Foot Washing. Chapter Five: A comparison between the Syriac Orthodox ordo and the commentary. In the second chapter one explores the development of footwashing, both in the west and the east in patristic and canonical sources.The ongoing discussion in the west seems to be whether the footwashing is considered as a sacrament or not, while the fathers in the east interprets footwashing as explicitly revealing the cross for his disciple. In this chapter one gets to know the views of the fathers such as Augustine, Ambrose, John Chrysostom etc. The Syrian fathers make the same connection as the eastern fathers but connects it however to baptismal theology which is found in Rom 6:4.The fathers of the Syrian Orthodox tradition presents also an allegorical and symbolic interpretations of the footwashing, especially during the early Middle Ages and later Middle Ages. The canonical sources presents two views 1. Canonical. 2. Monastic. The canonical sources are Elvira 305-6. And Toledo 694, Elvira does not encourage the practice of the footwashing due to it being practiced after the baptism. In Toledo footwashing is encouraged and it seems that this praxis was discouraged according to the canon itself, the monastic was seen all through the subchapter. It was the custom for the brothers to greet a guest by washing their feet. The third chapter is about the footwashing rite and its theological contrasts and the contemplation which makes it a rite itself. Chapter Four is divided in three commentaries. The three different gospel narratives exist in 1. Jn 12:1-11. 2. Lk 7:36-50. 3. Jn13:1-20. The different use of this commentary reveals for the reader how Bar Salibi conducted biblical theology and how these different biblical stories reveal his view on the footwashing in contrast with John 13. The Fifth chapter concern the differences and similarities between the footwashing rite and the patristic by comparing the structures and the main focus of the texts, differences and similarities between the theologies of the two texts become clearer. The two main questions in this thesis is 1. Is the first-hand source (footwashing rite) compatible theologically with the second-hand source (Dionysius Bar Salibi`s biblical commentaries The second question is how much Greek influence has influenced the footwashing rite in contrast to the biblical commentaries?
