- Description: The first six months of 1989 has proved to be as busy as predicted, and the demand for mediation and arbitration services has increased steadily during this period. Year on year, whereas there were some 120 mediations and 75 arbitrations during the first six months of 1988, there were 195 mediations and 117 arbitrations during the first six months of 1989. This increase in demand may be attributed to a number of factors. In the first place, with the ever increasing unionisation of workers in South Africa a wider range of parties are resorting to third party intervention to resolve disputes. Secondly, labour and management who have had experience of mediation and arbitration, have continued to use third party neutrals to assist them in the process of dispute resolution. And thirdly, given the current political climate and the attitude of the major trade union federations to the recent amendments to the Labour Relations Act, it is apparent that parties are turning with greater frequency to independent third party neutrals to assist them resolve conflict. There are, for example, an increasing number of recognition agreements which require that conflicts of right be adjudicated through private arbitration under the auspices of IMSSA. Some German multinationals have, in accordance with the IG Metaal Code of Conduct for German investors in South Africa, agreed to refer disputes of right to private arbitration. IMSSA has for some time now been cited in the disputes procedures of many recognition agreements as the source of mediators.

- Description: Claude Le Jeune (born at Valenciennes , ca. 1528; died at Paris, 1600) was a towering figure in French Renaissance music. In spite of this, few biographical details have survived the turmoils of his time , which was marked primarily by the Wars of Religion, the last years of the reign of the Valois, and the struggle of Henry IV for the crown of France. In order, therefore, to attain a more complete picture of Le Jeune's life and work, the general historical and spiritual background, circumstantial evidence, is considered more implicating much intensely than usual. The two dominating beacons in Le Jeune's life are his allegiance to the Reformed Faith , involving close connections to leading Huguenot figures, and his inclination towards Humanism, confirmed by his association, from 1570 onwards, with the Academie de Poesie et de Musique of Jean-Antoine De Baïf. The present study is concerned with the initial years of Claude Le Jeune, covering the thirty- seven years of his life from 1528 (the assumed year of birth) intil 1565. In terms of publications, this period includes his "youthful" works : four early chansons from 1552, the Dix Pseaumes with a dialogue for seven voices , Mais qui es-tu,of 1564, and a single motet à 3, Nigra sum sed formosa, published in 1565. The background of his northern homeland is screened with particular attention to the involvement of the members of the Le Jeune family in the religious affairs of the time. Also the general cultural and musical milieu of the Netherlands is investigated within this and Le Jeune's first published works are considered biographical framework. These works still bear the stodginess and gaucheness of an apprentice. The probability of a sojourn in Italy is explored with positive findings. This visit most likely brought Le Jeune within the circle of the ageing Willaert at Venice, Major focus is placed upon the Dix Pseaumes, the first comprehensive collection to appear entirely under Le Jeunes ' s own name and dominating the initial period of his creative life. Detailed analyses reveal the hand of a now asserted composer. well-versed in technical matters and in possession of a fine perception for both the tenets of Calvinism and the aspirations of musical Humanism . As far as the latter is concerned. pertinent attention is given to its roots in the rhetorical and philosophical traditions. and how Le Jeune accommodated issues which sprouted from these and occupied the theorists of his time. Musical text expression holds. since the Dix Pseaumes. a central place in Le Jeune's works in which he maintains a fresh and subtle approach steering clear of the dogmatism of some contemporary theorists. Using various musical devices (modes, chiavette, melody, rhythm, harmony, texture, and even structure) to serve text expression. Le Jeune' s parlance gradually develops a currency in its own right. often expressing the meaning or implication of a text more comprehensively than can be attained by means of a linguistic medium. Appropriate to this particular trait of development in language. recognition is given Le Jeune's musical language. Included into the discussion are concordances of works by other composers where these exist as well as references to the relevant musical topography. A concluding summary of the moulding forces in the initial years of Claude Le Jeune's life as well as the gradual formulation of his distinct musical language concludes this study which can be regarded as an introduction to a more comprehensive programme of research on the life, times and works of Claude Le Jeune, Huguenot and Musical Humanist.

- Description: The southern African yellowfish (Barbus aeneus, B. capensls, B. kimberleyensis, B. natalensis and B. polylepis) are very similar, which limits the utility of traditional taxonomic methods. For this reason yellowfish similarities were explored using multivariate analysis and karyology. Meristic, morphometric and Truss (body shape) data were examined using multiple discriminant, principal component and cluster analyses. The morphological study disclosed that although the species were very similar two distinct groups occurred; B. aeneus-B. kimberleyensis and B. capensis-B. polylepis-B. natalensis. Karyology showed that the yellowfish were hexaploid, B. aeneus and B. kimberleyensis having 148 chromosomes while the other three species had 150 chromosomes. Because the karyotypes of the species were variable the fundamental number for each species was taken as the median value for ten spreads. Median fundamental numbers were B. aeneus = 196, B. natalensis = 200, B. kimberleyensis = 204, B. polylepis = 206 and B. capensis = 208. The lower chromosome number and higher fundamental number was considered the more apomorphic state for these species. Silver-staining of nucleoli showed that the yellowfish are probably undergoing the process of diploidization. Southern African Barbus and closely related species used for outgroup comparisons showed three levels of ploidy. The diploid species karyotyped were B.anoplus (2N=48), B. argenteus (2N=52), B. trimaculatus (2N=42-48), Labeo capensis (2N=48) and L. umbratus (2N=48); the tetraploid species were B. serra (2N=102), B. trevelyani (2N=±96), Pseudobarbus afer (2N=96) and P. burgi (2N=96); and the hexaploid species were B. marequensis (2N=130-150) and Varicorhinus nelspruitensis (2N=130-148). The taxonomic implications of polyploidy for the African cyprinids were considered, and its effect on species was discussed.

- Description: The kinetic behaviour of anhydrous CrCl₃ in gaseous oxidising atmospheres has been examined in the temperature range 350 to 630°C in order to identify optimum reaction conditions and to establish the mechanism by which the reaction is controlled. The reaction under consideration is CrCl₃ (s) + ¾ O₂ (g) → ½ Cr₂O₃ (s) + ³/₂ Cl₂ (g). The main experimental techniques used were isothermal and programmed-temperature thermogravimetry, supplemented by scanning electron-microscopy, surface-area determinations and porosity measurements. The effects of sample pelletisation, gas flowrate, temperature, oxygen partial pressure, pellet porosity and the addition of other oxide species on the rate and extent of reaction have been studied. The reaction is shown to occur in a single step, starting at -350°C under non-isothermal conditions, and exhibiting a deceleratory rate over most of the reaction. Isothermal thermogravimetric curves were fitted to a number of kinetic rate expressions, and a series of statistical analyses used to identify the rate equation which best describes the experimental data. Supporting evidence was provided by scanning electron-microscopic examination of partially-reacted samples. It is concluded that the reaction is under chemical control, and that reaction occurs by means of a linearly-advancing reactant-product interface. The reaction kinetics can be described by a contracting-geometry rate expression. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

The life and times of Ethel Tawse Jollie : a case study of the transference and adaptation of British social and political ideas of the Edwardian era to a colonial society

- Description: This is an appraisal of the career of Ethel Tawse Jollie (1876-1950), the first woman parliamentarian in Southern Rhodesia, and the British Empire overseas, prolific writer and leading intellectual of her political generation who played a key role in the achievement of responsible government in Southern Rhodesia in 1923. As the founder and principal organiser of the Responsible Government Association she imported from Britain a singular political philosophy which made a lasting impression on Rhodesia's political character and social identity. She was an influential figure in British imperialist circles and in the women's suffrage controversy. No other Rhodesian politician had achieved such prominence in the metropole, or possessed such a thoroughly formed, comprehensive ideology, and the propaganda skills necessary to give it effect. The study traces the formation of her ideas within the intellectual milieu of pre-1914 Britain and - through her - its subsequent adaptation in Rhodesia; how, through her marriage to Archibald Colquhoun - explorer, writer and Cecil Rhodes's first Administrator of Mashonaland - she became steeped in the ideology of the Edwardian Radical Right - that reaction to imperial decline denoted by the slogan 'National Efficiency'. By 1915. when she arrived in Rhodesia, she had come to believe that by 1915, when she arrived in Rhodesia, she had come to believe that the salvation of the Empire lay in its 'patriotic' periphery where it was possible to create new societies on Radical Right principles. Both in and out of parliament she gave to Rhodesian public policy and identity a distinct Radical Right hue, which she further enhanced by her involvement in various extra parliamentary pressure groups. It is a life and times study and considerable use is made of contemporary ballads and novels in the belief that immersion in the atmosphere of the period is particularly useful in an intellectual biography of this kind. Comparisons are also made with other British peripheries notably Ulster, Canada and New Zealand. The study challenges the traditional view of Rhodesia as a neo-Victorian intellectual backwater; seeing it rather as a society which continued to import selectively ideas from elsewhere in the Empire. It should interest Commonwealth and - because of its central character - women's historians.

- Description: Few students of History understand the derivation and/or origin of the Gqunukhwebe oath "Ndifung' uChungw' efel' ennyameni: I swear by Chungwa who is lying dead at Mnyameni (Alexandria)." A desire to eludicate this point and other related facts inspired me to undertake a close examination of the history of the Gqunukhwebe people, selecting as my main theme the life-work of Chief Kama. In the first chapter I am discussing the creation of the Gqunukhwebe Chiefdom under Khwane by the Xhosa King, Tshiwo. The central theme here is the Black-White confrontation of the 17th - 18th centuries on the Cape Eastern Frontier. As a result of the collision the Gqunukhwebe people were forced to make a home on the banks of the Thwecu River along the east coast. It was here that Kama reached early manhood. The second chapter describes the establishment of Wesleyville Missionary Station by William Shaw in 1823, the first Methodist Missionary Institution in all Xhosaland. In chapter three the discussion centers on the significance of Kama's conversion. An unforeseen outcome of his public profession of the Christian faith was that it not only stigmatized the latter religion as a force destructive of the old order in Xhosa society, but it also reshaped Kama's political image for the good of his religious life. He not only fled from the neighbourhood of his relations and sojourned in a strange land, but also reinforced the Colonial forces in the contemporary frontier struggles. His integrity, self-sacrifice and pro-Colonial inclination eventually won him Middledrift. Chapter four opens with Kama's settling in Middledrift. The theme here is two-pronged. It presents the 'Cattle-Killing' delusion as a source of new trials for the 'priest-chief', and at the same time exposes the Colonial Government's efforts to gain ascendancy above the Xhosa chiefs. Kama's land was the first testing ground in this respect, and the Chief was initially agreeable to the scheme. Chapter five alludes to instances of Chief Kama's unco-operative attitude as signs that his compromising spirit had its limits. An atmosphere of disregard towards Kama pervades the period. But the adversities that threatened to dominate his later life did not by any means shake his Christian principles and convictions. The traces of his good works may to this day be seen in Middledrift, the traditional home of the Kamas.

- Description: The biosynthesis of ABA from R-[2-¹⁴C]-MVA was demonstrated in Persea americana cv. Fuerte mesocarp and in mature seeds of Hordeum vulgare cv. Dyan and cv. Himalaya. Radioactivity from R-[2-¹⁴-C]-MVA was also incorporated into the 1',4'-trans ABA diol in Persea americana mesocarp and a possible role for this metabolite as a precursor of ABA in plants is discussed. The biosynthesis of ABA from MVA could not be demonstrated in either turgid and waterstressed Hordeum vulgare cv. Dyan, Pisum sativum cv. Black-eyed Susan and Phaseolus vulgaris cv. Top-crop or in immature seeds of Pisum sativum and Phaseolus vulgaris. (R,S,)-[2-¹⁴C]-ABA was catabolised to PA, DPA and aqueous conjugates in leaves and mature seeds of Hordeum vulgare cv. Dyan, seedlings and immature seeds of Pisum sativum and Phaseolus vulgaris and in mesocarp from ripening fruits of Persea americana. PA and DPA were identified by either microchemical methods and/or capillary GC-MS. 7'-Hydroxy ABA was characterised as a novel ABA catabolite in light-grown and etiolated leaves of Hordeum vulgare by capillary GC-MS. Circular dichroism analysis revealed that it was derived predominantly from the (R)-enantiomer of ABA. This catabolite was absent in similar studies using the dicotyledons Pisum sativum and Phaseolus vulgaris. Refeeding studies with [¹⁴C]-PA, [C]-DPA and [¹⁴C]-7'-hydroxy ABA were used to confirm the metabolic interrelationship between ABA and its catabolites in both vegetative and non-vegetative tissues from monocotyledonous and dicotyledonous species. The methyl ester of (R,S,)-ABA was hydrolysed efficiently by light-grown leaves of Hordeum vulgare. Older, vegetative tissues catabolised (R,S,)-ABA more efficiently than their younger counterparts. In contrast, small, immature seeds of Pisum sativum catabolised (R,S,)-ABA more effectively than larger, immature seeds of this species. Light did not appear to influence ABA biosynthesis but markedly enhanced ABA catabolism. Light stimulated the overall rate of ABA catabolism in both vegetative and non-vegetative tissue. Water stress reduced ABA catabolism in Hordeum vulgare leaves but had little effect on this process in Phaseolus vulgaris seedlings. Pretreatment of tissues with (R,S,)-ABA retarded the catabolism of (R,S,)-[2-¹⁴C]-ABA, negating ABA-induced conversion to PA. Cycloheximide inhibited ABA biosynthesis and catabolism but did not affect ABA conjugation. Chloramphenicol and lincomycin had little or no effect on ABA metabolism suggesting that the enzymes involved were labile and cytoplasmic in origin. Ancymidol and cycocel inhibited ABA biosynthesis while AM01618 stimulated this process. The cytokinins, benzyladenine, kinetin, isopentenyl adenine and zeatin also inhibited ABA biosynthesis. These results are discussed in relation to the possible involvement of carotenoids in ABA biosynthesis. AM01618, ancymidol andcycocel did not significantly influence the conversion of ABA to PA and DPA while cytokinins appeared to enhance this process only in vegetative tissue. The information derived from these studies was then used in attempts to develop a cell-free system from higher plants capable of metabolising ABA. A cell-free system prepared from imbibed Hordeum vulgare cv. Dyan embryos biosynthesized and catabolised ABA. This is the first demonstration of a cell-free system from non-vegetative tissue capable of metabolising ABA and could prove useful for elucidating its biosynthetic route. This cell-free system generated the terpenyl pyrophosphates IPP, FPP and GGPP from MVA. ABA was produced from both MVA and IPP in the presence of 0₂ and NADPH. The biosynthesis of ABA was stimulated by the addition of the squalene 2,3-oxide cyclase and kaurene synthetase inhibitor, AM01618 and a "cold-pool trap" of (R,S,)-ABA. Ancymidol, cycocel and cytokinins reduced incorporation of label from MVA into ABA. Similar cell-free preparations, in the absence of AM01618, converted (R,S,)-[2-¹⁴-C]-ABA into PA, 7'-hydroxy ABA and water-soluble conjugates. Although the methyl ester of (R,S,)-ABA was efficiently hydrolysed in this cell-free system no DPA was generated. The possible involvement of mixed function oxidase activity and soluble oxidases is discussed in relation to ABA metabolism. While cell-free preparations from Persea americana cv. Fuerte mesocarp and immature seeds of Pisum sativum and Phaseolus vulgaris were unable to synthesize ABA from MVA, these tissue homogenates converted ABA into more polar acidic products. PA and DPA were identified as products of ABA catabolism in extracts from immature seeds of Phaseolus vulgaris and the l',4'-cis diol of ABA in extracts from Pisum sativum immature seeds

It was established that this need was not adequately filled by conventional university teacher-training methods. The literature about computerised simulation of role-playing and teaching activities was investigated and the investigation indicated that such simulations had been relatively successful. A published American computer simulation, TENURE, in which the student plays the role of a first-year teacher, was selected for modification to meet the needs of South African students. This program is implemented in the TUTOR computer language and runs on the Control Data South Africa PLATO system. In order to determine the needs of South African students, two groups of Rhodes University students worked through the simulation as it was being modified. The modifications were adapted according to the students' responses to a questionnaire. The simulation has been tested by 72 H.D.E. students and several educationists and the response has been positive

Yet Francis Bacon believed that "the suffering of people and the differences between people are what have made great art, and not egalitarianism ... " (Brighton and Morris, ' 1977: p.234 and 235). If it is true that art was once an integral part of society and reflected the aspirations of the whole community, its effect on society today has become marginal. Throughout history, especially since the emergence of Romanticism in the nineteenth century, the relationship between art, the artist and the public has become more and more tenuous. The spread of capitalism has resulted in widespread changes in methods of production, literacy, and industrial and technical development. Societies have become so diversified that today art no longer expresses the values and spiritual concerns of a unified society, but rather the individual or the small group. Given this, it has become impossible to return to a system of shared values and beliefs. To preserve some kind of 'truth', art has become a self-evolving activity, autonomous from political, social and economic concerns, and the term 'art for art's sake' is synonymous with many artists working in western capitalist societies.

- Description: Values education in geography can be seen as a way of educating pupils to think critically and independently on matters to which they can readily relate. It also involves the relating of facts and concepts of a subject area to the pupils ' own lives. There is, therefore, a need to introduce values education in geography at our schools. The DET geography syllabuses offer many topics of social and environmental concern. Valuing processes, based on values analysis and values clarification, can be used to teach these topics. Through values education, geography pupils can become more purposeful, more enthusiastic and positive in their learning. This study investigates the effectiveness of valuing strategies in the teaching of geography. A broad overview of the literature on valuing in general and valuing in geographical education in particular, was analysed. Three teaching units were then devised and tried out in KwaZulu schools. The responses of pupils to these units were then investigated through questionnaires. Teachers were also interviewed to find the extent to which valuing approaches were being used. The principal findings of the study are, firstly, that the pupils responded well to the valuing units. Secondly, that teachers were not using valuing strategies in schools and, lastly, that the units in the research could be effective in teaching values geography. From the findings of this research, it is evident that values geography has an important place in the South African school curriculum

- Description: Palaeoenvironmental reconstruction of the late Pleistocene and Holocene geological periods for central and southern Africa has been hampered by the erratic distribution of suitable sites, incomplete and inaccurately dated sequences and the limited nature of published data. One geomorphological feature which has supplied valuable evidence for fluctuations in past environmental conditions, is the vlei or dambo. The type-site of these waterlogged features is in south central Africa, but similar features have been described on other continents. The clastic and organic sediments contained within these features are affected by, and therefore reflect to some degree, the environment under which they were formed. The characteristics of the sediments supply information as to their transport and mechanisms of deposition. From these processes, the environmental conditions at the time of vlei formation can be inferred. The environmental history of the Eastern Cape region has been considerably neglected, and is far less well understood than other countries such as Malawi, Zambia and Zimbabwe. A study site in the Winterberg Range (Eastern Cape) was selected which permitted the comparison of two vleis, the objective being to establish an accurate late Pleistocene sediment chronology for the entire plateau area. Radiocarbon dates from organic layers indicate that these sediments span the last 12 000 years BP, suggesting that organic accumulation at this site began at roughly the same time as at sites further afield. The vlei sediments are analysed in terms of their morphology, particle slze distribution, and other physical and chemical characteristics. These data facilitate the construction of detailed stratigraphic diagrams and a chronological summary of sediment accumulation, from which the period and governing processes of vlei development under changing environments may be described. It is found that the Winterberg vleis contain sediments which respond to changes in the prevailing environment. This makes these sediments useful indices from which to trace such changes during the late Pleistocene and Holocene times. These features are found to be similar in many respects to those described elsewhere in Southern Africa. The study attempts to provide greater understanding of contemporary vlei processes and emphasises the necessity of their preservation, as finite and valuable resources, by future generations

At the request of readers, the Cape Action League decided to publish the series as a booklet. The book is written in easy English in order for it to be used by workers and their allies as an instrument for active struggle against all forms of oppression and exploitation. The story of Jane G has its roots in the daily experiences of an ordinary black working mother living in South Africa/Azania. She is the mother you meet at the bus stop, meet in the taxi, talk to at the corner shop or prayer meeting. In this series, Jane G’s struggle is typical of the millions of workers suffering a similar fate in our country. Jane speaks of the hardship she faces under the exploitative cycle of earning low wages and paying high rents. The burden of working long hours and paying high prices for basic food in order to look after her family. She finds relief by joining the Clothing Workers’ Union which organises workers at the Rex-Tex factory where she works.

- Description: Excess thermodynamic properties have been determined for several binary liquid mixtures with the aim of testing various thermodynamic theories and postulates. Excess molar enthalpies, HEm, have been determined using an LKB flow microcalorimeter and excess molar volumes, VEm, have been determined using an Anton Paar vibrating tube densitometer. The activity coefficients at infinite dilution ƴ∞₁₃, have been determined using an atmospheric pressure gas-liquid chromatograph. The excess molar enthalpies and the excess molar volumes have been measured at 298.15 K for systems involving the bicyclic compounds decahydronaphthalene (decalin), 1,2,3,4-tetrahydronaphthalene (tetralin), bicyclohexyl, or cyclohexylbenzene mixed with 1- hexene, 1-hexyne, 1-heptene, 1-heptyne, cyclohexene, 1,3-cyclohexadiene, 1,4- cyclohexadiene, or benzene. These excess properties have also been measured for systems where the bicyclic compound has been replaced with benzene, cyclohexane or n-hexane. The results show defmite trends related to the size, shape, and the degree of unsaturation of the component molecules. The Flory theory has been used to predict excess molar enthalpies and excess molar volumes for {(a bicyclic compound or benzene or cyclohexane or n-hexane) +(an n-alkane or a 1-alkene or a 1-alkyne or a cycloalkane or cyclohexene or a cycloalkadiene or benzene)}. The one parameter equations offer reasonably good correlations between the predicted and the experimental results. More insight into the origins of the contnbutions to the excess thermodynamic properties for these systems has been gained by considering the approximate equations of Patterson and co-workers, which separate the interactional and the free volume contributions to the excess molar enthalpy and the excess molar volume. The one parameter equations have adequately rationalized a good deal of the observed behaviour for HEm and VEm. The theory of Liebermann and co-workers, which does not employ any adjustable parameters, has not been as successful at predicting the excess thermodynamic properties for the above systems. The activity coefficients at infinite dilution have been measured at 278.15 K, 288.15 K and 298.15 K for n-bexane, 1-bexene, 1-hexyne, n-heptane, 1-heptene, 1-heptyne, cyclohexane, cyclohexene, 1,3-cyclohexadiene, 1,4-cyclohexadiene, and benzene, in decalin, tetralin, bicyclohexyl, and cyclohexylbenzene. Solvent losses from the column have been accounted for by an extrapolation procedure. The activity coefficient results together with the HEm and VEm values have been used to calculate the partial molar excess thermodynamic properties of mixing at infinite dilution. The partial molar excess properties at infinite dilution for decalin mixtures are similar to those for bicyclohexyl mixtures. There is also a similarity between the properties of the tetralin mixtures and the cyclohexylbenzene mixtures. The cycloalkadienes, benzene and the 1-alkynes exhibit a strong dissociation effect on being mixed with the saturated solvents, decalin and bicyclohexyl, but associate strongly with tetralin and with cyclohexylbenzene. The Flory theory bas been used to predict activity coefficients at infinite dilution from the experimentally determined HEm results for { (n-bexane or 1-hexene or 1-hexyne or naheptane or 1-heptene or 1-beptyne) + (a bicyclic compound)}. The theory is much better at predicting values for mixtures where both components are either saturated molecules or are unsaturated molecules than for {saturated + unsaturated} mixtures.

- Description: Excess thermodynamic properties have been determined for several binary liquid mixtures with the aim of testing various thermodynamic theories and postulates. Excess molar enthalpies, HEm, have been determined using an LKB flow microcalorimeter and excess molar volumes, VEm, have been determined using an Anton Paar vibrating tube densitometer. The activity coefficients at infinite dilution ƴ∞₁₃, have been determined using an atmospheric pressure gas-liquid chromatograph. The excess molar enthalpies and the excess molar volumes have been measured at 298.15 K for systems involving the bicyclic compounds decahydronaphthalene (decalin), 1,2,3,4-tetrahydronaphthalene (tetralin), bicyclohexyl, or cyclohexylbenzene mixed with 1- hexene, 1-hexyne, 1-heptene, 1-heptyne, cyclohexene, 1,3-cyclohexadiene, 1,4- cyclohexadiene, or benzene. These excess properties have also been measured for systems where the bicyclic compound has been replaced with benzene, cyclohexane or n-hexane. The results show defmite trends related to the size, shape, and the degree of unsaturation of the component molecules. The Flory theory has been used to predict excess molar enthalpies and excess molar volumes for {(a bicyclic compound or benzene or cyclohexane or n-hexane) +(an n-alkane or a 1-alkene or a 1-alkyne or a cycloalkane or cyclohexene or a cycloalkadiene or benzene)}. The one parameter equations offer reasonably good correlations between the predicted and the experimental results. More insight into the origins of the contnbutions to the excess thermodynamic properties for these systems has been gained by considering the approximate equations of Patterson and co-workers, which separate the interactional and the free volume contributions to the excess molar enthalpy and the excess molar volume. The one parameter equations have adequately rationalized a good deal of the observed behaviour for HEm and VEm. The theory of Liebermann and co-workers, which does not employ any adjustable parameters, has not been as successful at predicting the excess thermodynamic properties for the above systems. The activity coefficients at infinite dilution have been measured at 278.15 K, 288.15 K and 298.15 K for n-bexane, 1-bexene, 1-hexyne, n-heptane, 1-heptene, 1-heptyne, cyclohexane, cyclohexene, 1,3-cyclohexadiene, 1,4-cyclohexadiene, and benzene, in decalin, tetralin, bicyclohexyl, and cyclohexylbenzene. Solvent losses from the column have been accounted for by an extrapolation procedure. The activity coefficient results together with the HEm and VEm values have been used to calculate the partial molar excess thermodynamic properties of mixing at infinite dilution. The partial molar excess properties at infinite dilution for decalin mixtures are similar to those for bicyclohexyl mixtures. There is also a similarity between the properties of the tetralin mixtures and the cyclohexylbenzene mixtures. The cycloalkadienes, benzene and the 1-alkynes exhibit a strong dissociation effect on being mixed with the saturated solvents, decalin and bicyclohexyl, but associate strongly with tetralin and with cyclohexylbenzene. The Flory theory bas been used to predict activity coefficients at infinite dilution from the experimentally determined HEm results for { (n-bexane or 1-hexene or 1-hexyne or naheptane or 1-heptene or 1-beptyne) + (a bicyclic compound)}.

- Description: The principal intention of this study was to explore the heuristic value of the story of the alchemical vessel in understanding borderline conditions and pursuing their psychotherapy. It establishes the pertinence of the case study as a method of exploring the content and process of psychotherapy. The essential nature of story-telling is examined and the hypothesis is made that psychotherapy, borderline conditions, the myth of the alchemical vessel and the case study all reflect instances of story-telling. Towards the end of examining their mutual reflection, and thus heuristic value, elements of Jungian theory, the phenomenology of borderline conditions and case material are examined. Through the examination of certain shared themes which emerge from the story of the alchemical vessel and the material of psychotherapy it is established that there is indeed a metaphoric resonance between the different stories. Furthermore this resonance is useful in that it provides a secure vantage point as well as guidance towards effecting transformation for the client. The validity of the metaphoric resonance is examined and areas of weakness highlighted. Some suggestions are made concerning further research.
