- Description: The title, "'n Intertekstuele studie: Die werfbobbejaan van Alexander Strachan", refers to an analysis of the way in which intertextual processes generate meaning in this text. It is analysed with specific regard to the way in which it enters into signifying and detennining relationships with other texts, notably texts by the same author. A significant part of the intertexts that are reassembled, refined, restated, amplified, contradicted or diffused throughout Die werfbobbejaan are located in other works in the Strachan oeuvre: n Wereld sonder grense (1984) and Die jakkalsjagter (1990). These three texts are related as a triptych of intertextual association, and the boundaries between them are not hermetically sealed. Intertextual activity in Die werfbobbejaan involves an intricate network of interfigural relationships. The identities of numerous characters in the text start to coincide with those of other characters to which they are linked intertextually. Characters travel across the boundaries supposedly separating "different" texts. The doubling and displacing of characters alert us to the fact that the text is not fixed within stable boundaries. Codes, scenes, snippets of dialogue and even moods also penetrate the boundaries between "different" texts and recur in the form of mirror images or ghostly transformations of themselves. These intertextual patterns mobilise an active reading process and unify the act of reading with that of writing in "a single signifying process" (Barthes 1979: 79). The narrator in Die werfbobbejaan is a woman writing a biography about an author. Reading his novels and unpublished manuscript she finds that the manuscript of her subject anticipates and later even dictates "extra-textual" reality and inserts her into the fiction. The way in which the biography is taken up in the play of intertextuality leads to the perception that the fictional author is an intertextual mirror image of the real author, who belongs to the extra-textual world outside the book. In this way intertextual activity in Die werfbobbejaan destabilizes the frame between fiction and reality. No reading of Die werfbobbejaan can be complete without taking into account the plurality of simultaneously perceived meanings triggered by intertextual activity in the text.

- Description: The study period saw a significant increase in the urbanisation of whites and blacks in Port Elizabeth induced by droughts and coercive legislation, but also by burgeoning industrialisation. Industry had been given great stimulus by World War 1 and maintained by protectionist legislation in the 1920s which the local state and industrialists came to endorse. The ethos of the town was overwhelmingly British in terms of the population, the composition of the local council, business interests and the prevailing culture. Whites formed the largest component of the population in Port Elizabeth during the inter-war years. The majority of white women lived in the North End, the industrial hub and a major working class area of the city. Although the provision of housing was initially neglected, economic and subeconomic housing in the 1930s helped to create both racial separation and a sense of community between sectors of the working class. Yet, white working class women did not form a homogenous group, but rather consisted of different ethnic groups, occupations and classes. The Afrikaans speaking sector, formed a significant component of the industrial labour force especially in the leather, food and beverage and clothing industries. In a centre where white labour was favoured and marketed as an advantage to outside investors, they rapidly displaced coloured women. The female workforce was basically young, underpaid (especially in comparison to wages on the Rand) and temporary. While white women were still in evidence in other occupations such as domestic work and in the informal sector, their numbers here steadily diminished as both racial segregation and municipal regulation, were implemented. Against a background of chaotic social conditions, large slum areas and the spread of infectious diseases, the local council did much to improve health services particularly for women and children. Poor relief instituted in 1919 was, however, less forthcoming and female - headed households were often left to rely on the services of local welfare organisations. The extended family, however, was the norm affording support against atomization. Although pressurised by social ills throughout the period, the family was increasingly buttressed by state assistance. Prevailing morality was likewise actively constructed in terms of legislative repression and racial division. This often lead to social aberrations such as infanticide which was only reduced by the increase of state assistance and, in the longer term, social mobility of the whites.

- Description: This study is a critical analysis of selected works of the playwright Maishe Maponya namely, The Hungry Earth, Jika and Gangsters. The main thrust of the analysis of the thesis is centred on questions around what 'Commitment' might mean in literature and drama. This concept has appeared in many names and guises. In theatre, it has assumed names like Theatre of Commitment, Theatre of the Dispossessed, Theatre ofthe Oppressed, Theatre of Resistance, as well as Theatre of Radicalization (Bentley 1968; Boal 1974; Mda 1985; Maponya 1992). These names came into existence as a result of a concerted effort to refrain from the use of the traditional conventional theatre, which does not appear to address itself to societal problems - the preoccupation of Theatre of Commitment. Chapter One is principally concerned with the concept of Commitment and its implications in art and literature, more specifically in theatre. Further, the following interacting elements in South African theatre are highlighted: censorship, banning, detention and other restrictions, as well as DET education and religious institutions. Finally, Maponya is introduced, with his political inclinations and his views on art, together with the issue of theatricality in his plays. Chapter two initiates the proposed critical analysis with a focus on The Hungry Earth. The focus is on Theatre of Commitment and the background events that inspired Maponya's response. Chapter three concerns itself with the critical analysis of Jika, "a play about the making of revolutionaries in South Africa ... and serves a political purpose - as a recording of pivotal moment in South African history ... " (Haysom, 1988: 1). An attempt is made to assess the extent to which the playwright has succeeded or failed to strike a chord harmonious with the pronouncements quoted. Chapter four ends the critical analysis with the treatment of Gangsters. Here an observation is made on the fusing of the three personas, namely Rasechaba, Biko and Maponya, into one symbolic whole representing the image of Jesus Christ on the cross - the Saviour who sacrificed His life for the salvation of sinners. Maponya is seen to have sacrificed his time and energy for the liberation of the downtrodden. The conclusion summarizes the study by placing the selected works in their suitable perspective in respect of the notion of Commitment in literature, with particular reference to theatre. Maponya is seen to have played a commendable role in the liberation of his peoples' minds by teaching them the business of organizing revolutions, as well as by championing the liberation struggle.

- Description: The diet of Cygnodraco mawsoni Waite 1916 and Gymnodraco acuticeps Boulenger 1902 (Pisces: Bathydraconidae) was studied in the Cooperation and Cosmonaut seas in the depth range 200–400 m during the summer 1988. Stomach content analysis showed that both species are piscivorous predators but with different feeding habits. Cygnodraco mawsoni fed mostly on young notothenioid fish, regularly complementing these with pelagic, Euphausia superba, and benthic crustaceans, such as amphipod gammarids and mysids. In contrast, G. acuticeps relied mostly on mesopelagic fish of the family Myctophidae. Although C. mawsoni and G. acuticeps occupy similar depths in the Cosmonaut Sea, different feeding habits appear to limit the probability of interspecific competition for food.

- Description: For the purpose of this study tbe child witness in the accusatorial system will be viewed as a source of information. When a witness gives evidence in court, the function of the witness is to provide the court with certain information. A number of crucial questions arise when the witness is a child. Do children bave the ability to remember and relate an event accurately? Are children prone to suggestion and fantasy? What effect, if any, does the court environment have on a child 's ability to convey information? What perceptions do children have about the legal process, and how do these perceptions affect their ability to testify? Do adults influence the information which children impart by the techniques they employ to obtain such information? Accepting the hypothesis that child witnesses are sources of information, the purpose of this study is to evaluate all aspects of the criminal justice system relating to child witnesses as well as available research on children to determine whether it is possible to obtain reliable and accurate information from children. Proposals will be formulated regarding the most successful methods of obtaining reliable and accurate information from children, and how these can be adapted for use by the legal system. The purpose of the study is to develop an approach to children in the legal system that will be fair to children while at the same time protecting the rights of the accused, and which will lead to a successful method of obtaining accurate information.

- Description: Not unlike Spain after Franco in the 1970s, post-Apartheid South Africa in the 1990s, is a state whose democracy is built on a broad based effort to manage a transformation towards constitutionalism and the open rule of law. In what is still an ongoing process towards the transformation of public life, a democratising South Africa remains a prime example of one of the most hopeful democratic orders in the Southern hemisphere. How this state, engaged in transformation at home, projects itself in its relations with other, largely less democratic states abroad, represents a test for the evolution of a foreign policy which pays heed to both economic need as well as its newly won democratic credentials. In the country's relations with Asia, the attempt to strike a balance between the two concerns, is something which points, more than anything else, to the ongoing, evolving nature of South African foreign policy.

- Description: Several camphor and pinane derivatives have been synthesised and evaluated for use as chiral auxiliaries in asymmetric synthesis. Various blocking groups have been attached to the camphor skeleton in attempts to improve stereofacial selectivity; these include α-methoxybenzyl and xylyl groups, and novel stereoisomeric ketal moieties derived from meso- and (R,R)-(-)-2,3-butanediol. Benzylation reactions carried out on the lithium enolates of ester derivatives of the camphor-derived chiral auxiliaries afforded α-benzylated products in 5-60% diastereomeric excess. Stereochemical aspects have been explored using high resolution NMR, X-ray crystallographic and computer modelling techniques, and hydrolysis of selected α-benzylated products has permitted the diasteroselective bias to be confirmed. Opposite configurations at the new stereogenic centre are clearly favoured by the xylyl and ketal blocking groups - an observation rationalised in terms of the presence or absence of chelating potential in the blocking group. Baylis-Hillman reactions carried out on a series of specially prepared camphor-derived acrylic esters containing the ketal blocking group exhibited both low diastereoselectivities (0-30% d.e.) and very long reaction times. Chiral silyl enol ethers, synthesised using both pinane and camphor derivatives as chiral auxiliaries, showed up to 20% diastereomeric excess in MCPBA oxidation, alkylation and Mukaiyama reactions. Attempts to bring the prochiral centre in the silyl enol ether substrates closer to the chiral auxiliary, and thus improve the stereofacial selectivity, proved unsuccessful. The silyl enol ether derivatives, however, display interesting fragmentation patterns in their electron impact mass spectra, which were investigated using a combination of high resolution MS, comparative low resolution MS and metastable peak analysis.

- Description: The amino acid, tryptophan, obtained through dietary means, is metabolised by the enzymes tryptophan 2,3-dioxygenase (TDO), indoleamine 2,3-dioxygenase (IDO) and tryptophan hydroxylase. All the enzymes have an effect on circulating tryptophan levels, especially TDO, since it is the major site of tryptophan catabolism in the liver and results in the production of kynurenine metabolites, viz. kynurenine, kynurenic acid, 3-hydroxyanthranilic acid and quinolinic acid. Extrahepatically, IDO is responsible for the synthesis of the kynurenine metabolites. Tryptophan 2,3-dioxygenase and IDO activity is increased by hormones or substrates such as tryptophan, and inflammation, in the case of IDO. Tryptophan availability for serotonin (5-HT) synthesis by the enzyme tryptophan hydroxylase is primarily dependent on TDO activity. A study was attempted in order to ascertain whether any of the endogenous metabolites of the kynurenine and serotonergic pathways would be able to inhibit TDO activity. Results showed that although the kynurenines had no effect, the indoleamines, except for the indoleacetic acids, were able to reduce TDO activity. 6-Methoxy-2-benzoxazolinone (6-MBOA), a structural analogue to melatonin, was the most potent inhibitor with a reduction in activity of 55 % compared with the control. The pineal gland in the rat brain has been shown to have the highest IDO activity. With induction, the kynurenine metabolite concentrations of kynurenic acid and quinolinic acid are increased. The effects of both compounds were determined on the serotonergic pathway. Although kynurenic acid produced no significant effect, quinolinic acid significantly reduced N-acetylserotonin and melatonin synthesis at concentrations of lOJLM and 100 JLM respectively. Many authors have implicated oxygen derived species as causative agents in the important neurodegenerative disorders such as Parkinson's and Huntington's disease. Increased radical generation and lipid peroxidation have been suggested to be responsible for the toxic destruction of neurons, especially in the brain because of its high lipid content and oxygen demand. The brain is therefore vulnerable to oxidative attack. During inflammatory diseases, IDO is induced with a resultant increase in kynurenines. This study was also an attempt at determining the effect of kynurenines on lipid peroxidation. All metabolites of the kynurenine pathway were able to induce lipid peroxidation significantly. The antioxidative potential of various tryptophan analogues, viz. serotonin, melatonin and 6-methoxy-2-benzoxazolinone, was determined using quinolinic acid-induced lipid peroxidation. Serotonin, melatonin and 6-MBOA were able to significantly reduce quinolinic acid-induced lipid peroxidation.

- Description: The aims of the project were twofold. The initial objective of the study, based on previous results, was to develop an economically viable methodology for immobilizing yeast cells for the treatment of heavy metal-laden waste water. The non-viable yeast cross-linked by 13% (w/v) formaldehyde/1N HNO₃ exhibited satisfactory mechanical strength and rigidity in a continuous-flow column operation. No apparent disruption of the biomass after repeated use was observed. The cost of immobilizing 1kg dry yeast pellets was estimated at less than US$I. Zn uptake capacity of FA-cross-linked pellets, on batch trials, remained similar to that of raw yeast, reflecting that the immobilizing procedure did not hinder its metal removing capacity. In column studies, cation metals were effectively removed by the yeast pellets from aqueous solution at natural pHs, and then recovered completely by washing the pellets in situ with O.1M HCl. The recovered metals were concentrated in such small volumes that recycling or precipitation of them was facilitated. The metal uptake capacity of the regenerated biomass remained constant in comparison with cycle 1, indicating that reuse of the yeast would be possible. In the case of Cr⁶⁺, a gradual breakthrough curve of Cr in the column profile was noted, with a simultaneous reduction of Cr⁶⁺ to Cr³⁺. However, Cr⁶⁺ in the effluent can be markedly minimised either by accumulation onto the biomass or reduction to its trivalent form. Desorption of bound Cr⁶⁺ with either alkali or salt could not accomplish the regeneration of the biomass. A combination of reduction and desorption with FA/HNO₃ appeared promising in regeneration of the saturated biomass at 4°C. The metal sorption capacities of the yeast pellets, on a batch or a fixed-bed system are relatively lower than that of documented sorbents. Apparently more of the yeast pellets would be required for treating a certain volume of waste effluent, than with other sorbents. Therefore Azolla filiculoides was examined as a suitable sorbent for this purpose. This constitutes the second part of the project. Azolla filiculoides, a naturally-abundant water fern, was screened for its metal sorption and recovering capacities, mechanical stability, flow-permeability and reusability. The azolla biomass appeared to have fulfilled the required mechanical criteria during the repeated sorption-desorption column operations. It is water-insoluble and appears flexible under pressure when rinsed with water. These characters are of crucial importance in a continuous-flow system since a column can be operated at high flow rates without apparent compact of the biomass and pressure loss. Therefore, immobilization of the biomass can be avoided. The sorption isotherm data, obtained from batch removal of Cr⁶⁺, showed that the sorption process was effective, endothermic and highly pH dependent. Considerable amounts of Cr⁶⁺ were accumulated at the optimum pHs of 2-2.5. Column sorption of Cr⁶⁺ at a low flow rate and pH of 2.5 showed optimum performance with a total Cr uptake of 50.4mg/g at 60% saturation of the biomass. Removal of Cr⁶⁺ from an electroplating effluent using an azolla column was deemed reasonably satisfactory, although the uptake declined slightly. Desorption of bound Cr⁶⁺ with various desorbents was incomplete, which resulted in a low regeneration efficiency of about 50%. However, removal and recovery of Cr³⁺ using the azolla column was than that of Cr⁶⁺. Desorption of Cr³⁺ from the spent biomass column was accomplished with the recovery of 80% using O.5N H₂SO₄, The regeneration efficiencies for Cr³⁺ removal were up to 90% and demonstrated that the biomass is reusable. Cation metal uptake capacities of azolla, obtained either from batch or column experiments, are reasonably high in comparison with other sorbents. The uptake of Ni or Zn ions from solution is pH dependent showing the optimum pH of around 6 to 6.5, under the current experimental conditions. The sorption kinetics for cation metals was rapid with about 80% of the bound Ni ions being taken up in the first 10 min. The character of rapid binding is extremely important in a column sorption process, especially on a large scale since it favours an optimum uptake of metals at high flow rates. The Ni or Zn uptakes in column sorption were not markedly affected when the flow rates were increased from 80mllh up to 800ml/h for the 5g biomass used. The cation heavy metals removed from waste effluents were recovered in a concentrated solution of small volume. The desorption of bound Ni and Zn ions from the saturated biomass was accomplished with either O.2N HCl or H₂SO₄ that resulted in recoveries of more than 95%. The metals recovered, in the case of Ni and Zn, are identical to that of plating agents ego nickel sulphate or chloride, so that recycling of the metals is possible. An effluent-free, closed loop of Ni or Zn treatment system was proposed, whereby the Ni or Zn ions can be recycled to the plating bath whilst the purified water is fed back to the rinse tanks. Ca and Mg ions, commonly present in the electroplating effluents, appeared to affect sorption of heavy metals by azolla when metal concentrations were relatively low, presumedly through its competitive binding for the shared sites on surfaces of azolla. The data obtained from column sorption of Ni and Zn follows the BDST model well, enabling the application of the model to predicting design parameters for scale-up of the biosorption column system. It is interesting that the values of metal uptake, expressed in molar quantities, obtained on respective single-metal solutions and the multiple metal system, are similar, implying that the mechanisms involved in the sorption of all metal cations are similar and that the binding sites on surfaces of azolla are probably shared by all cation metals. The surface of the biomass provides sites for metal binding estimated in the range of 0.45-0.57mmol/g, based on the current experiments. The biomass has a surface area of 429 m²/g and water retention of 14.3 ml/g. The functional groups on the surface of azolla were partially identified using chemical modification and metal binding comparison. Among the functional groups examined, carboxyl groups, provided by amino acids and polysaccharides, appeared to play an important role in metal cation binding. The infrared spectra of the samples support this conclusion.

- Description: This study examines the notion of universal human rights in the context of the importance of social and economic rights for the agency and dignity of human beings. It argues that the recognition of basic rights to what is necessary for physical well-being is essential to any adequate theory of human rights, and that rights of the civil and political variety depend on the recognition of social and economic rights if they are to be exercised. Therefore the secondary status which is usually accorded to social and economic rights results in an imbalanced ideal of human rights both in theory and in practice. This study is an attempt to place second generation rights in their proper context and to argue for them as human rights of equal status and importance. It focuses on the derivation of human rights in general, and shows that second generation rights may be accommodated within this structure. It further supports this position by showing that the categorical differences which are asserted to exist between first and second generation rights are based on a mistaken conception of positive and negative rights and duties, as well as an inadequate conception of liberty. The thesis shows that all rights generate a variety of duties, both positive and negative, and that an adequate theory of rights has to be able to accommodate the inevitability of conflicts of rights at the level of their enforcement. Consequently, this study argues there is no reason to give either class of right primary importance, as both first and second generation human rights are essential to the agency and dignity of a human being, and they are thus interdependent. Furthermore, the thesis shows that human rights can be balanced at the level of the obligations which they generate without compromising the deontological nature of such rights. This thesis argues that a theory of rights which is rooted in the liberal democratic notion of rights, such as that characterised by the choice theory of rights, is inadequate. It therefore argues that a benefit theory of rights must be adopted in order to accommodate conflicts of rights when they arise. The thesis argues that as such conflicts of rights are" most common in cases involving the assertion of social and economic rights, this balancing of rights is of special significance for the enforcement of second generation rights. Furthermore, this thesis argues for a theory of minimal interdependence of first and second generation rights, in order to accommodate the notion of first and second generation rights of equal status and importance, as well as to prevent an inflation of rights claims which would compromise the balancing of rights. It is argued that a reordering of values is necessary to take account of material well-being, as well as civil freedom, as both of these generate fundamental rights of equal status and importance.

- Description: This thesis explores the effect of some parameters on the breaking strain, strength and the shape of the stress-strain curve of bovine leather as revealed by uniaxial tensile tests. The parameters explored are fatliquoring, moisture content, strain rate and cyclic stressing. A basic mechanical model of a simple two-dimensional weave is created and used to describe the effect of such a weave on the shape of the stress-strain curve. It is found that fatliquoring lubricates and opens up the fibre structure and thereby makes the weave more extensible. The increase in the extensibility depends on the direction in which samples are cut and therefore the manner in which the fibres are orientated. Patliquoring is observed to increase the degree to which fibres pull out at break. There are indications that the strength of fatliquored leather decreases with time of storage, while the extensibility increases. The effect of the strain rate on the breaking strain, the tensile strength and the shape of the stress-strain curve is not very clear. The stressing and releasing leather decreases the strength of leather when the fibres are orientated preferentially along the direction of the applied stresses, but has an insignificant effect in the transverse direction. It is concluded that the degree of lubrication in a weave and the orientation of the fibre bundles significantly influence the performance of leather in a test. Both moisture and fatliquoring lubricate the weave. In both the cases the degree of fibre adhesions in a weave is decreased. A well lubricated weave allows its constituent fibres to slide and align along the direction of the applied stresses, and this tends to occur before the fibres themselves areextended. Cyclic testing, at low strains, ruptures fibre adhesions and as a result induces permanent set and makes a hide softer. Most of the work done in breaking the fibre adhesion is done in the first cycle.

In a review of the cognitive aging literature, the implications of a differential perspective were drawn out in order to establish a theoretical and methodological basis for an investigation into variability. A number of regularly occurring patterns, identified on the basis of available reports in the literature, were used to develop a model of variability (the shuttle model). The empirically-based model was located broadly within a neuropsychological framework, and derived explanatory power from the tenets of brain reserve capacity (BRC) theory. It served to describe the bulge in interindividual variability due to aging (the shuttle bulge), and the shifting occurrence of the bulge in relation to the age axis due to cohort and task-related influences (the shuttle shift). A two phase research study was conducted in order to test hypotheses derived from the model. Phase 1 comprised between-groups analyses of normative data covering a broad range of neuropsychological tests in the domains of attention, memory, language, visual and hand motor skills, in order to examine the progression of variability effects across the adult age range. Phase 2 constituted between and within-groups analyses of normative data from a more limited number of neuropsychological tests. It included the examination of raw score distributions and the characteristics of outliers, and was undertaken to explore more closely the nature of the variability phenomena detected in the first phase of the analysis. Taken together, the results of both phases of the investigation revealed statistically significant variability effects in support of the shuttle model. There was a consistent pattern of increased variability in association with older age regardless of functional modality; frequently, in association with later old age, there was also a subsequent decrease in variability (the shuttle bulge). The age of onset of the initial increase in variability occurred earlier or later (the shuttle shift) as a function of four factors: education, gender, task challenge and age-sensitivity of task. The finding of an earlier onset of variability effects for low education, male gender, high task challenge and high age-sensitivity of task was interpreted in terms of BRC threshold theory. The clinical and social implications of the outcome were discussed with special emphasis on the need for a differential perspective on aging, as a complement to the prevailing normative tradition. It was concluded that the shuttle model has considerable heuristic value. It presents an integrative framework for understanding existing variability data and provides clear indications for future research.

- Description: Temporary rivers in dryland regions are subject to highly variable and unpredictable rainfall and flow, and are considered unstable systems relative to perennial rivers of temperate zones. Little is known of the ecology of South Africa's temporary rivers, despite their abundance. The research presented focusses on the aquatic invertebrates inhabiting intermittently-flowing rivers in the 'arid corridor' of the Eastern Cape, South Africa. The major aims of the work were: to investigate which invertebrates inhabit these rivers, how the fauna is affected by environmental variability at various spatial and temporal scales, whether or not a characteristic fauna can be associated with these rivers or the hydrological phases which characterise them, and to establish to what extent faunal overlap occurs between different temporary rivers and between natural and modified temporary and perennial rivers. Research results indicate that the fauna of the Eastern Cape temporary rivers shows little structure at the scales of investigation, and that communities are generally non-equilibrial in character. The major forces shaping the biota are considered to be physical rather than biological, and the most important of these are: present and antecedent hydrological conditions and their duration; time of year; and biotope character, extent and heterogeneity. Three groups of fauna were identified as inhabitants of the temporary rivers: 'residents', 'facultative taxa' and 'opportunist colonists'. Taxa were tentatively allocated to these groups. Faunal resemblance was fairly high in Eastern Cape temporary rivers at the level of family, but not at more detailed taxonomic levels. A comparison between faunas of temporary and perennial rivers in different regions of South Africa illustrated the influence of geographical location on diversity. Within regions, however, there was no indication that perennial rivers were more diverse than intermittent rivers. The relatively high diversities in temporary rivers in this study are attributed at least in part to the heterogeneity in surface water conditions over time. A conceptual framework envisioning a continuum between perennial and temporary rivers is proposed as a basis for ongoing research into these rivers. A supporting terminology for the range of river flow types in South Africa is presented.

- Description: This study discusses the extent to which Charles Sturridge's Where Angels Fear to Tread, Merchant Ivory's Howards End, and David Lean's A Passage to India have aimed at, and succeeded in, exploring the thematic concerns of E.M. Forster's novels. A brief introductory chapter explains the motivation behind this research, and the choice of critical methodologies used. It concludes with an outline of some of the problems confronting film-makers wishing to explore the concerns of novels. The first chapter, which is devoted to Where Angels Fear to Tread, reveals that while Sturridge is "faithful" to Forster's novel at a superficial level, basing most of his scenes on, and taking most of his dialogue directly from, the text, he does not explore Forster's themes. The facility with which film tells stories proves to be a treacherous trap for Sturridge. His version of Where Angels Fear to Tread is totally vacuous because he failed to develop anything beyond the story -- Forster's "tapeworm" of time (Aspects of the NoyeI41). The causality that Forster calls plot seemed beyond Sturridge's comprehension, leaving his film little more than an endless progression of "and then[s]" (Forster, Aspects 87). Characters are not given their full weight; symbols and leitmotifs are overlooked; the allegorical elements he did recognize, he failed to understand, and thus misplaced, so that the epiphanic moments of the novel are lost. There is no possibility of thematic concerns emerging from a film in which plot, characterization, symbol and rhythm are ignored. Sturridge's apparent inability to understand his source is in stark contrast to Merchant Ivory's sensitivity to Howards End, and their evident familiarity with literary criticism on the work. Chapter two explores the way in which their adaptation smooths out putative flaws in characterization and plot, and uses filmic rhythm and camera work to suggest comments made by the novel's narrator. Almost wholly successful in developing the novel's themes, Merchant Ivory's Howards End does not, however, successfully explore the spiritual dimensions of Forster's novel. Film is a medium capable of great subtlety, but its strength lies in its ability to capture the seen; the unseen tends to evade its grasp. It is in dealing with the unseen that Lean's A Passage to India misses greatness, for in virtually every other respect his version of Forster's masterpiece is superb. Chapter three explores Lean's creative and flexible approach to adaptation, his acute sensitivity to the differing demands of film and novel, and his confident technical mastery. It also explores, however, the emptiness at the heart of his film, an emptiness that is the result of his trivialization of the spiritual concerns of Forster's novel.
