Studies of some cocondensations of nickel atoms with unsaturated organic ligands and with mixed ligand systems

The cocondensation of nickel with a number of unsaturated ligands was studied, as was the cocondensation with a number of mixed ligand systems. Enamines were found not to react with nickel while acrylonitrile was polymerized. In the mixed ligand syst.ems different products were obtained than when the ligands were cocondensed individually. Cocondensations of benzyl halide/allyl halide mixtures gave unstable products that were not observed when the halides were cocondensed individually. The effect of Kao-Wool insulation on nickel/benzyl halide cocondensations was found to be significant. Kao-Wool caused the bulk of the benzyl halide to be polymeri zed to a number of poly-benzylic species. An alkali metal reactor was designed for the evaporation of sodium and potassium atoms into cold solutions of metal halide and an or ganic substrate. This apparatus was used to synthesize Ni(P¢3 )3' but proved unsuccessful for synthesizing a nickel-enamine compound.

Teachers' perceptions of effects of terminal examinations on teaching and learning at the secondary school level in Zimbabwe

This study was particularly aimed at the examinations and the effect they have on schooling at the secondary school level in Zimbabwe. The views and opinions of teachers on the use of terminal examinations for certification and the influence they are seen to have on teachers' approach to the curriculum were examined. The literature has shown that there is widespread criticism of the justice and effects of terminal examinations. It is argued that they lead to an over-emphasis of that which is measured, knowledge and intellectual ability, at the expense of that kind of education progress which is almost impossible to measure in an end-of-the-course assessment. Three hundred and six secondary school teachers responded to a survey which asked for teachers' perceptions of examinations and the curriculum. The findings of this study indicated that teaching is structured towards examinations. Although teachers are trying to teach and develop reasoning skills and other activities, the pressure of examinations and the importance of doing well in them force teachers to restrict themselves to examination requirements.

Therapeutic Recreation Education in Canada: A Review of the Current Curriculum

Abstract This descriptive study sought to identify the similarities and differences between the various educational institutions offering therapeutic recreation curriculum across Canada. The study utilized mixed methods, including open and closed-ended questions on a survey and document analysis. The research participants were from 14 educational institutions located across the nation. Results from this study identify similarities and differences in the curriculum used to prepare students pursuing a career in the TR field. Core competencies and standards of practice for the field of therapeutic recreation were defined and discussed. Accreditation and the accrediting bodies in the field of TR are reviewed because of their significant impact on curriculum. Implications regarding certification and regulation pertaining to the education for therapeutic recreation practitioners were discussed along with suggestions for future research.

Global Education in the Shifting Classroom: Refocusing the Teacher Lens Through Study Abroad

Academic exchange programmes provide opportunities for teacher candidates to study at educational institutions abroad wherein they are able to learn more about different cultures, teaching practices, and build cross-cultural relationships. This paper is an exploration into my teacher candidate experience abroad. The relevant research on this topic indicates that teacher certification should take an active role in creating opportunities for teacher candidates to participate in educational experiences abroad because of their benefits. The knowledge that a teacher gains through abroad experiences is one of the strongest factors in helping to build authentic global classrooms. In addition, these programmes allow for fuller understanding of a global context and the chance to understand someone else’s story. This review and synthesis of literature and research findings prepares a foundation for how teacher candidates, and hopefully, how policy makers can work toward creating a more inclusive global classroom for students.

An Analysis of Minor Hockey Officials and Perceived Organizational Support

Recent research suggests organizational factors should be considered in order to better understand the attrition of minor hockey. Consequently, the purpose of this quantitative study was to examine the extent to which minor hockey officials perceive organizational support (POS) from the minor hockey system, and to compare POS among minor hockey officials according to demographics. A total of 261 minor hockey officials were surveyed with the Survey of Perceived Organizational Support (SPOS). Results indicated significant differences according minor hockey official experience, certification level and extra-role performance. The findings are discussed in relation to POS and human resource management literature, and recommendations are made as to how administrators can better support these officials.

Identification and characterization of a Catharanthus roseus mutant altered in monoterpenoid indole alkaloid biosynthesis

The Madagascar periwinkle [Catharanthus roseus (L.) G. Don] is a commercially important horticultural flower species and is the only source for several pharmaceutically valuable monoterpenoid indole alkaloids (MIAs), including the powerful antihypertensive ajmalicine and the antineoplastic agents vincristine and vinblastine. While biosynthesis of MIA precursors has been elucidated, conversion of the common MIA precursor strictosidine to MIAs of different families, for example ajmalicine, catharanthine or vindoline, remains uncharacterized. Deglycosylation of strictosidine by the key enzyme Strictosidine beta-glucosidase (SGD) leads to a pool of uncharacterized reaction products that are diverted into the different MIA families, but the downstream reactions are uncharacterized. Screening of 3600 EMS (ethyl methane sulfonate) mutagenized C. roseus plants to identify mutants with altered MIA profiles yielded one plant with high ajmalicine, and low catharanthine and vindoline content. RNA sequencing and comparative bioinformatics of mutant and wildtype plants showed up-regulation of SGD and the transcriptional repressor Zinc finger Catharanthus transcription factor (ZCT1) in the mutant line. The increased SGD activity in mutants seems to yield a larger pool of uncharacterized SGD reaction products that are channeled away from catharanthine and vindoline towards biosynthesis of ajmalicine when compared to the wildtype. Further bioinformatic analyses, and crossings between mutant and wildtype suggest a transcription factor upstream of SGD and ZCT1 to be mutated, leading to up-regulation of Sgd and Zct1. The crossing experiments further show that biosynthesis of the different MIA families is differentially regulated and highly complex. Three new transcription factors were identified by bioinformatics that seem to be involved in the regulation of Zct1 and Sgd expression, leading to the high ajmalicine phenotype. Increased cathenamine reductase activity in the mutant converts the pool of SGD reaction products into ajmalicine and its stereoisomer tetrahydroalstonine. The stereochemistry of ajmalicine and tetrahydroalstonine biosynthesis in vivo and in vitro was further characterized. In addition, a new clade of perakine reductase-like enzymes was identified that reduces the SGD reaction product vallesiachotamine in a stereo-specific manner, characterizing one of the many reactions immediately downstream of SGD that determine the different MIA families. This study establishes that RNA sequencing and comparative bioinformatics, in combination with molecular and biochemical characterization, are valuable tools to determine the genetic basis for mutations that trigger phenotypes, and this approach can also be used for identification of new enzymes and transcription factors.

Chemical, biochemical, and molecular characterization of a low vindoline Catharanthus roseus mutant.

The Madagascar periwinkle (Catharanthus roseus) is the sole source of the anticancer drug vinblastine, which is formed via the coupling of monoterpenoid indole alkaloids (MIAs) catharanthine and vindoline. A mutant line of C. roseus (M2-1865) with an altered MIA profile was identified in a screen of 4000 M2 lines generated by ethylmethanesulfonate (EMS) chemical mutagenesis. While this line did not accumulate vinblastine due to reduced levels of vindoline within the leaves, significant levels of 2,3-epoxide derivatives of tabersonine accumulated on the leaf surface. Detailed nucleotide, amino acid, and enzyme activity analyses of tabersonine 3-reductase in the M2-1865 line showed that a single amino acid substitution (H189Y) diminished the biochemical activity of T3R by 95%. Genetic crosses showed the phenotype to be recessive, exhibiting standard Mendelian single-gene inheritance. The usefulness of EMS mutagenesis in elucidating MIA biosynthesis is highlighted by the results of this study.
