associations are also being investigated using A-domain deletion mutants, atToc159GM and atToc132GM as well as A-domain swapped mutants 159A132GM and 132A159GM. This investigation has revealed that the mechanisms governing TOC GTPase interactions in Arabidopsis may be dictated by the A-domain of atToc132 and the G-domain of atToc159, thereby giving insight into how key TOC components are assembled into distinct TOC complexes at the chloroplast surface. Distinct complexes are responsible for the critical identification and import of different subsets of preproteins, all of which are necessary for plant growth and development.

The DMA adsorption kinetic data showed fast and slow rates, consistent with the formation of more than one type of adsorbed DMA complex. Apparent pseudo adsorption and pseudo desorption rate constants were extracted from the dependency of the initial adsorption rates on [DMA(aq)]. Desorption rate constants were also extracted from desorption experiments using hydrogen phosphate and chloride solutions, and were found to be higher by 1- 2 orders of magnitude than those using chloride.

The phosphate adsorption kinetic data showed adsorption rate constants of phosphate on Fe-(oxyhydr)oxide films increase in this order: arsenate-covered < DMA-covered £ freshly-prepared. Also, desorption rate constants of DMA complexes were 7 times higher than arsenate using phosphate as a desorbing agent. When these results are combined with earlier work on the thermodynamics, kinetics, and structure of surface complexes, this data suggests that, within minutes to 1 hr of surface interaction, increasing organic substitution on arsenate increases the proportion of relatively weakly-bonded complexes (ie. monodentate and outer-sphere).

We also synthesized a series of discotic compounds based on substituted dibenzo[a,c]tetracenedione, dibenzo[a,c]pentacenedione and tetrabenze[a,c,d,f]pentacenedione, with 4, 4 and 8 aliphatic side chains, respectively, using similar methodologies to that of the dibenz[a,c]anthracene compound. These compounds were also found to exhibit columnar mesophases. The mesophase temperature range suggests that the larger aromatic core stabilizes both the crystalline and liquid crystalline phases. The dione functional groups also give a synthetic handle for further synthetic modifications to probe the structure-property relationships of these PAHs.

To elicit EBE, students serving as Es administered Ss Rosenthal’s Photo Rating Test (RPRT), a series of photographed faces which Ss rate on an ordinal “success-failure” scale. Some Es were led to expect that their Ss would perceive “success” in the faces; other Es expected their S to perceive “failure.”

In a preliminary study RPRT was examined by having students rate the pictures on two occasions under neutral, i.e., “no-expectancy” conditions. Only 11 out of the 20 pictures received near-zero ratings, and a large rating dispersion was found. Consequently, results were calculated separately for all the pictures and for the most “neutral” ones.

Focussing on S personality variables, Experiment One tested the hypothesis that Ss who were more submissive to authority were also more susceptible to EBE. Ss selected for either high or low dominance were given RPRT by medium dominant Es were led to expect high ratings and others to expect low ratings from their Ss.

Simultaneously, focussing on E variables, Experiment Two tested the hypothesis that dominance and submission in E affected S’s susceptibility to EBE. The task and the expectancies given to Es were the same as in Experiment One.

In both experiments E and Ss were classified as dominant, medium dominant or submissive if they scored within the upper, middle, or lower range of their sample’s distribution on Gold’s Dominant-Submission Scale. The interaction between dominance and experimental situation responses was examined bya hidden observer, recording smiles, glances and test duration, and by post-test questionnaires.

No EBE was found in either experiment, yet submissive Ss reported a significantly higher pressure to rate the pictures in a certain way than dominant Ss.

The results of both studies were interpreted in terms of problems surrounding this area of research. Finally, a proposed model of personality and situational variables which can be expected to elicit EBE was presented.

Four hypotheses were formulated. The first one stated that there existed a negative relationship between perception of Gentiles’s attitudes (GA) and positive attitudes toward Israel (AI). That hypothesis was supported.

The second hypothesis stated that there existed a negative relationship between self esteem (SE) and positive attitudes toward Israel (AI). That hypothesis was also supported.

the third hypothesis stated that when high positive attitudes toward Israel (HPAI) are found, there will also be found low self esteem (LSE) and perception of Gentiles’ negative attitudes (NGA) in the same subject. This hypothesis was not supported.

The fourth hypothesis stated that when low positive attitudes toward Israel (LPAI) are found, there will also be found high self esteem (HSE) and perception of Gentiles’ positive attitudes (PGA) in the same subject. That hypothesis was not supported.

Three main effects were examined. Firstly, it was found that the oldest people had the most favorable attitude toward Israel, while the youngest people had the least favorable attitude towards Israel. Secondly, no significant difference was found between males and females in their attitudes toward Israel. Finally, religious affiliation was found to be an important factor in Jewish attitudes toward Israel. The more orthodox the people are, the more favorable are their attitudes toward Israel.

The findings were discussed in the context of intergroup relations, reactions to prejudice and discrimination, as well as minority-majority relationships.

Implications were drawn for improving the relationship between the Israeli Government and Jewry in Canada. Suggestions were also made for future research.

The results were supportive of the general hypothesis. Stepwise regression analysis revealed that a warm, organized classroom was significantly positively related to peer self-concept, family self-concept, and student satisfaction with teacher and peers. A supportive, innovative teaching style was also significantly positively related to student peer self-concept. Competition was found to relate negatively to student scholastic self-concept.

With respect to teacher satisfaction, no relationship was found between teacher satisfaction and student self-concept. However, a significant relationship was found between teacher satisfaction with students’ performance and students’ satisfaction with teacher. Competition related positively to teacher satisfaction with students’ performance and a supportive, innovative teaching style was negatively related to teacher satisfaction with him/herself as a teacher.

Significant positive relationships were also found between self-concept, happiness, and student satisfaction. Finally, gender was found to be a significant predictor of peer, scholastic, and family self-concepts, happiness, and students’ satisfaction with peers, with girls scoring significantly higher on these variables than boys.

The results were discussed in terms of their implications for existing educational theory and practice and for the creation of growth-producing environments in classrooms.

The research approach is described and is supplemented by an explanation of the role of the researcher as a part of the setting. The researcher’s entry and effort to gain a sense of legitimation in the setting is also discussed. A specific community project was used as the vehicle for this study and community characteristics and project history are illustrated as background for the researcher’s involvement. A model of community development was developed and illustrated through specific activities. The value of a community needs assessment in the community development process is highlighted and illustrated by the researcher’s work in the community.

Finally, this study provides a consideration of the importance of community development, both for its initiators and participants. Based on the research findings and a discussion of their importance, conclusions were made about the value of local community efforts to individual and community health. Insights into community organization practice are presented.

The results of this study will indicate to medical social workers when and in what areas treatment around discharge to home situations should begin. This would be preventative social work, following the identification of a potential problem-solving situation. There might be a use for family therapy here in fostering some husband/father role retention and in preparing all members of the family to deal with the necessary adjustment in accommodating the long absent family member. Treatment of patient groups might be a method of helping the men foresee their problems and motivate their resources to deal with them as effectively as possible.

A sediment texture comparison between modern and ancient environments indicates that higher energy pervailed in the ancient environment relative to the present day environment. The cobble and gravel sediments as well as an extensive belt of foredunes preserved in the ancient environment are evidence of this high energy.

Sediment textural parameters of mean, standard deviation, skewness, and kurtosis were combined in bivariate plots to test their reliability for discriminating between environments. Results from four combinations of those parameters were not totally favourable. Only a plot of standard deviation versus skewness proved useful.

Component populations are useful discriminators of depositional environments. Inferred environments of beach, fluvial, and dune as well as modern lacustrine sediments could be identified by the characteristics of their component population curves. Moreover, characteristic curves that represent various subenvironments for the modern near shore zone are evident. These have been assimilated into a grain size distribution facies indicator.

Provision of a facies model for a barred-lacustrine bayhead was made possible by an examination of preserved bedforms and primary sedimentary structures. High energy bedforms of parallel laminae and massive bedding are always preserved to low energy ripple cross-laminae. The sequence of ripple cross-laminae that forms in response to increasing energy as as follows: symmetrical, assymetrical, oscillatory, and combined flow. An examination of such preserved features yields information that can be used to decipher flow directions, energy gradients, and flow characteristics within specific subenvironments.
