The influence of African migrant parents on their children's career choices in a new culture

Peter Akosah-Twumasi explored the acculturation strategies and perceived parental influences on career constructions among Sub-Saharan African youth migrants in Australia. He developed three theoretical models, which provided in-depth understanding of the positive parental roles and identified challenges with reconciling personal interests with parents' expectations. His results could foster development of more inclusive counselling interventions

Investigation and Synthesis of Novel Aromatic Azo Inhibitors of LMW-PTP Isoform B

The goal of this investigation was to synthesize novel aromatic azo inhibitors based on an aromatic azo inhibitor discovered from in silico screening against Low Molecular Weight Protein Tyrosine Phosphatase (LMW-PTP). These inhibitors were then tested in vitro aginst LMW-PTP Isoform B. The synthesis of the inhibitor of interest was achieved via a Sandmeyer reaction, utilizing p-aminobenzoic acid. The nucleophile used in the synthesis, 3-hydroxy-2-naphthoic acid, was linked with p-aminobenzoic acid, and the final product was purified via recrystallization. Characterization techniques included 1H-NMR, 13C-NMR, COSY, and HMQC. This newly synthesized product was an analogue to a previously synthesized competitive inhibitor, 156563, which had an inhibitor dissociation constant of 33.5μM. By synthesizing an analogue to inhibitor 156563, our group hopes to probe the carboxylic acid chain length as a function of inhibition

A Cross-Disciplinary Study of Citation Types in the Literature Review Section of MPhil Theses

Citation practices are inevitable in academic writing, but different disciplinary communities have different preferences. This study is a cross- disciplinary study of citation types in the literature review section of MPhil theses. Employing a qualitative approach, textual analysis of thirty theses selected from the disciplines of English and Curriculum Studies was carried out in addition to an analysis of interview data from lecturers and MPhil students of the selected disciplines. A key finding of the study was that while students of the Department of English used more integral citations, students of Curriculum Studies preferred non-integral citations. Integral citation was found with active sentences, S-genitive forms, and multiple forms of citations. Non-integral citation, however, was realised in numerical, single sources, sources with and without pages. While integral citation was used when the information was central to the discussion, non-integral citation was used when the information was peripheral and assumes the status of a general knowledge. The study adds to existing literature on disciplinary variation

Osmotic potential of Zinnia elegans plant material affects the yield and morphology of tracheary elements produced in vitro

The Zinnia elegans cell suspension culture is excellent for xylogenesis studies at the cellular and molecular level, due to the high and synchronous in vitro differentiation of tracheary elements (TEs). The percentage TE differentiation (%TE) in the culture is, however, influenced by a number of factors before and during cell differentiation. One of the factors that is potentially important but has not gotten much attention is the initial osmolarity of the plant material. To examine whether the growth conditions that determine leaf osmolarity (LO) affect the final %TE, we used three light intensities (50, 70 and 100 mu mol.m(-2)s(-1)) and three electrical conductivity (EC) levels (EC 2, 4 and 6 dS.m(-1)) in hydroponic systems to induce different osmolarities in leaf materials from two cultivars (cvs) of Z. elegans, Envy and Purple Prince. The isolated leaf mesophyll cells were subsequently cultured in a liquid medium (300 mOsm extracellular osmolarity) containing alpha-naphthalene acetic acid (NAA) (1 mg.l(-1)) and benzylaminopurine (BA) (1 mg.l(-1)). The LO increased in both Zinnia cvs with increasing light intensity and increasing EC during growth. Mesophyll cell size correlated negatively with EC, but the correlation was positive with light intensity in both Zinnia cvs. There was an overall positive correlation between % TE and LO although the degree of % TE change versus LO differed between light and EC treatments and also between the two Zinnia cvs. Envy cv is the best known Z. elegans cv for establishing xylogenic cultures. However, it turned out that by subjecting the plants to different growth conditions, the Purple Prince cv produces a higher % TE as compared to the Envy cv. At EC4 the TE differentiation for the Purple Prince cv was 75%, a level that is 25 to 60% higher than those earlier reported. We conclude that light intensity and EC of the root environment affect the LO of Z. elegans which in turn influences the development and therefore dimensions of TEs in an in vitro xylogenic culture. Thus, proper optimization of the growth conditions for the Zinnia plants prior to establishment of xylogenic cultures leads to enhancement of in vitro TE formation
