- Description: The aim of this study was twofold: 1) to educate and inform the student population about sexual harassment, and 2) to evaluate which one of two different training programs would be more effective in increasing awareness of sexual harassment on campus. A pre-test post-test group design was implemented. A sample of students (N=132) living in 14 different Rhodes university residences participated in the study on a voluntary basis. Subjects were divided into two groups. Group 1, participated in a workshop based upon a video entitled One man's meat is another man's poison, produced by the University of Cape Town. Group 2, was subjected to a more passive educational method where the video was played from beginning to end without any interruption. Awareness of sexual harassment was operationalised in terms of the subjects' attitudes towards sexual harassment, their perceptions of sexual harassment, and their sexual harassment myths. Results suggested a significant relationship between participation in the training programs and a change in awareness of sexual harassment, as measured by the changes in the pre-test and post-test scores. Results also suggested that males benefit most by simply viewing the video, while females benefit most by workshopping the same video. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This research project is about infant-observation, that is looking at, observing, and studying parent-infant interactions and relationships within the first year of life. The principle intention of the study is to illustrate and shed light upon human infant development and how the newborn becomes a fully functioning member within the family. The study provides a context in which to consider parent-infant interaction beginning in utero, expanding to the birthing process, and continuing through the infant's first year. It focuses on specific themes of parent-infant interaction. The following situations are explored: the role of the mother; the mother as a container; the infant's experience of containment; the internalisation of experience; the symbolic meaning of food; dealing with distress and the development of concrete communication; the growth of a sense of ego; and, the infant's internal world. The study concludes by addressing various implications for further psychotherapy and compares the therapist-client relationship to the mother-infant relationship. The research outlines one particular psychoanalytic theoretical orientation of mental and emotional development. It is a model derived predominantly from The Developmental School Theorists and Object Relations Theorists, namely, Bowlby, Klein, Mahler and Winnicott. This model looks at the infant's earliest relationships and the processes these set up within the infant's developing mind. Infant observation, asa research method proposed by Bick and Sidoli, links method and theory, and serves as the methodological approach utilised in the present study. A video, based on the parent-infant interaction of three families, provides observational data and may be viewed in conjunction with this research. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Sewage effluents disposed into the marine environment from De Beers Marine Namibia diamond mining vessels have the potential to cause endocrine disruptive effects in marine organisms. Endocrine disruption refers to the alteration of the normal functioning of the endocrine system and various chemicals have the ability to mimic hormones, effecting endogenous hormone synthesis, transport, receptor interaction and intracellular signaling. The potential endocrine disruptive effects, caused by the release of different types of sewage effluents into the ocean, on fish species is a concern due to the commercial importance of fish species found in the mining area e.g. hake, sole, horse mackerel. Increased awareness of marine environmental degradation due to the presence of chemical contaminants has resulted in research being done on early warning systems, in the form of biomarkers. Cytochrome P450 monooxygenase 1A (CYP1A) and vitellogenin (vtg) are important proteins found in fish liver and blood, that have been used as biomarkers for the detection of pollutants in fish. CYP1A is a subfamily of the P450 superfamily of enzymes and catalyzes the oxidation, hydrolysis and reduction of exogenous and endogenous compounds (phase I reactions) and thus has the capacity to regulate the metabolism of several organic contaminants. CYP1A expression is altered by exposure to planar xenobiotic compounds e.g. polyaromatic hydrocarbons. Vtg is an important precursor for egg yolk proteins and plays a role in the growth and development of an oocyte. Expression of this protein is altered upon exposure to estrogenic compounds. The aim of this project was to isolate CYP1A from fish liver by differential centrifugation and optimize conditions for the CYP1A-mediated ethoxyresorufin-Odeethylase (EROD) assay and western blot analysis (to assess CYP1A expression). Another aim of this study was to evaluate the potential effects of biologically disruptive chemicals from sewage effluents, discharged into the marine environment, on the expression of CYP1A in two species of hake, Merluccius capensis and M. paradoxus (Cape hake). CYP1A in Cape hake is approximately a 60 kDa protein and the highest EROD activity was detected in the microsomal fraction after differential centrifugation. Optimal EROD assay conditions were observed at pH 7.5, a temperature of 25 °C, 10 μl of sample and a reaction time of 30 seconds. Enzyme stability assays indicated a drastic decrease in enzyme activity after 30 seconds. The EROD assay was not NADPH dependent but was limited by NADPH supply, with an increase of 300% in EROD activity being observed with the addition of 0.1 M exogenous NADPH. The addition of dicumarol (40 μM), a phase II enzyme inhibitor, showed a 232% increase in EROD activity. This is because dicumarol inhibited enzymes with the capacity to metabolize the product (resorufin) of the EROD reaction. With regard to western blot analysis, the optimal primary (rabbit antifish CYP1A peptide) and secondary (anti-mouse/rabbit antibody-horseradish peroxidase conjugate (POD)) antibody dilutions were determined to be 1:1000 and 1:5000, respectively. The comparison of CYP1A expression in Cape hake samples from De Beers Marine mining area and reference sites showed higher EROD activity (16.29 ± 0.91 pmol/min) in fish samples from the mining area in comparison to the reference site (10.42 ± 2.65 pmol/min). Western blot analysis was in agreement with the EROD assay results and a higher CYP1A expression was observed in fish from the mining sites. The increased CYP1A expression observed in fish from the mining area is not definitively an indication of a pollutant effect in the environment, as several environmental and biological factors (e.g. photoperiod and age) must also be considered before reaching this conclusion. Another aim of this study was to purify vtg from Cape hake blood samples. Cape hake vtg was purified from fish plasma by selective precipitation with MgCl2 and EDTA. Precipitated sample was subjected to anion exchange chromatography using fast protein liquid chromatography (FPLC). Vtg eluted as two broad peaks and had a molecular weight above 200 kDa. SDS-PAGE analysis also resolved smaller molecular weight proteins below 70 kDa, which were thought to be vitellogenin cleavage proteins, lipovitellin and phosphovitins. Western blot analysis was performed; however, it did not produce any conclusive results. The purification of vtg enables further studies in characterizing this protein and developing assay aimed at detecting estrogenic pollutants in the marine environment

- Description: The quality of the Bender-Gestalt performance of 22, normal, white South African male adolescents and 22, normal, Xhosa male adolescents, aged between 17 and 22 years, was investigated. The Pascal-Suttell scoring system was used. The mean score of the white adolescents was significantly below that of the Xhosa adolescents. It was found that while the mean score of the Xhosa adolescents was within one standard deviation of Pascal and Suttell's normative 'high school' mean, the mean score of the white adolescents was below that of the normative mean and not within one standard deviation of the mean. The results lend support to the findings that Bender performance is related to cultural background. It is suggested that the Pascal-Suttell tables may be in need of revision. The advisability of standardising tables, which are culture specific, for clinical use· in the Southern African context, is indicated. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The effects of repeated mild concussive head injury on professional rugby players were examined. Data were collected for rugby players (n=26) and cricket player controls (n=21) using a comprehensive neuropsychological test battery comprising five modalities (Verbal Memory, Visual Memory, Verbal Fluency, Visuoperccptual Tracking and Hand Motor Dexterity) and a self-report Postconcussive Symptomology Questionnaire. Group statistical comparisons of the percentage of individuals with deficit were carried out for (i) rugby versus cricket; (ii) rugby forwards versus rugby backs; and (iii) rugby forwards versus cricket. Rugby players performed significantly poorer than controls on SA W AIS Digit Symbol Substitution subtest and on the Trail Making Test. On Digits Forward and Digit Symbol Incidental Recall, the results approached significance with the rugby players showing a tendency toward impairment on these tests. Rugby players exhibited impairment in areas of visuoperceptual tracking, speed of information processing and attention, and there are tendencies of impairment in verbal and/or visual memory. Results obtained on the self-report questionnaire strongly reinforced cognitive test results and a significant proportion of rugby players reported difficulties with sustained attention, memory and lowered frustration tolerance as well as symptoms of anxiety and depression. It was consistently noted that players in the more full contact positions (rugby forwards) were most susceptible to impairment, confirming that these players, who are exposed to repeated mild head injuries, are at greater risk of exhibiting postconcussive sequelae , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This thesis explores the meaning and experience of the bodily states associated with the condition referred to as myalgic encephalomyelitis (ME). It uses as a theoretical point of departure an understanding of the body as a socially constructed phenomenon and, in so dOing, offers an interpretation of illness that is seen to differ markedly from those offered by the medical and behavioural sciences. Using descriptive narrative research analysis, the thesis attempts to elicit personal trajectories of illness experience. In contrast to biomedical and social trajectories of illness, in which the interpretation and meaning given to the condition are imposed externally, personal trajectories are seen to provide unique subjective accounts of illness experience. And the value of using narrative accounts of illness is seen to lie in their ability to bring to light these individualised versions of illness experience. It is shown, in addition, that these narrative accounts of illness are also valuable in exposing the culturally shared knowledge that is employed in the process of assigning meaning to illness experiences. The aim of the thesis, then, in employing the descriptive narrative research method is to describe these shared cultural schemas. It is suggested that this approach leads to an interpretation of illness experience which sheds light on important links between the body, self and society. It is argued, more specifically, that Western capitalist society is associated with the creation of an "unnatural" environment and social context which is perceived to be inherently damaging and threatening to the well·being of those living in it; and that this assumption is pivotal to the interpretation of the illness experiences narrated and analysed for the thesis. This sociological reading of embodiment provides a basis for understanding the experience of illness, as not one simply embedded in the body or mind of the individual, but as one laden with personal meaning assimilated from, and hence revealing of, the social context in which the illness is experienced. As such, an attempt is made to provide an account of illness experience distinct from the dominant biomedical and behavioural accounts of ME.

- Description: "Organisation development is a planned, systematic process in which applied behavioral science principles and practices are introduced into ongoing organisations toward the goal of increasing individual and organisational effectiveness. " [French and Bell] This study describes and analyses the implementation of Organisation Development (OD) to an Anglican Church theological seminary, The College of the Transfiguration (Cott), in the Anglican Church of the Province of Southern Africa (ACSA). The origins of OD are business related, emerging in the late 1950s and early 1960s. Over the years, and recently in South Africa, OD has been applied in educational change initiatives. Unlike more traditional change strategies, OD promotes collaboration in organisational change processes through the inclusive participation of all stakeholders. This study is unique in the sense that OD is applied to an Anglican Church theological institution in Southern Africa. The goal of theological institutions, particularly Cot!, is to "form, inform and transform" (Cot! Prospectus, 2011) those who feel called to ordained ministry. Personal experience in this practice has confirmed that organisational emphasis is placed more on product than process; on results rather than the leadership and management of the organisation. This study was an attempt to introduce a process of planned change to such an organisational context. OD was introduced to The College of the Transfiguration in the form of action research using the Survey Data Feedback (SDF) strategy. Data gathered was interpreted and analysed, followed by action planning and implementation of agreed plans. The process had a positive impact on both stakeholders and the organisation despite the challenges associated with the unpredictable world of organisations. Ultimately, I propose tentative recommendations which could help Cott and other educational institutions to achieve long-term improvement in organisational leadership and management.

- Description: The demand for systems i·ntegration has become more and more significant in higher education as institutions want systems that provide coherent information with data that is up to date and not redundant and can seamlessly support the end user experience. Institutions have become more reliant on information systems to support both administrative functions and those involved in teaching, learning and research, but because each department supports a diverse array of computing platforms and applications, it becomes very difficult to integrate these systems. SOA is classified as an innovative approach to integrating existing systems involving the use of independent services that can be accessed without knowledge of the underlying platform implementation. Unfortunately, the SOA initiative will not be success if it is not understood and used correctly by various applications and systems throughout the organisation. SOA introduces complexity and challenges in systems integration, acceptance, governance, data, development planning, security and external opportunities. If an organisation does not embrace or enable change in each of these areas, it is not ready for the adoption of SOA. This research investigates the systems integration challenge in selected South African universities and explores factors for SOA adoption. The framework for the adoption of SOA comprises seven factors, of which Systems Integration is the most significant and represents an efficient starting point for institutions considering SOA adoption. Acceptance, Governance, Data, Development Planning, Security and External Opportunities are other factors of SOA adoption that require careful and thorough consideration before an institution can successfully adopt SOA. The results of this research emphasise the importance of being able to embrace change and innovation and modify strategies in order to reflect the constant changes required for the adoption of SOA. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Despite a wealth of literature on the aetiology of somatic distress or somatization, somatic theory has failed to expand beyond a dualistic epistemology of causation. Within the primary health context where medically unexplained symptoms are characteristically articulated as literal, symbolic gestures of internal psychological processes, individuals' subjective accounts of somatic distress are reduced to objective phenomena and thus articulated on the grounds of absence. Within this context, the body as a lived, meaningful, perceiving subjectivity is silenced in favour of the corpse, thus rendering the somatizing individual's lived and subjective experience, expression and knowledge of somatic distress inaccessible. Instead, the somatizing individual is positioned within a domain of perturbed silence - a domain in which the professional's turning away or retreat from engaging somatization on the grounds of unique, subjective and corporeal experience, positions the patient/client as a passive, silent recipient whose somatic expressions as lived are overlooked. This study attempts to initiate a theoretical focus of departure from existing articulations of somatic distress through the development of a theoretical and epistemological framework that addresses some of the tensions inherent to contemporary somatic theory. In so doing, it employs embodiment philosophy and narrative methodology as a basis for a preliminary and critical investigation into a relatively neglected area of somatization research. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This study investigates the impact of the Times of Zambia gender policy on journalistic practices. The policy was formulated to address issues of representation of women both in news coverage and at an institutional level. In spite of the implementation of the editorial gender policy, no change in gendered representation is evident. As a media practitioner and a Zambian woman concerned with social justice, I set out to investigate the impact of this policy on journalistic practices. The study is informed by a Cultural Studies approach to media studies, specifically drawing on the 'circuit of culture' (du Guy et ai, 1997) and focused on two specific 'moments', namely representation and production. Data was collected using two qualitative methods, namely document analysis and semi-structured in-depth interviews. The document analysis established that this policy is informed by a liberal feminist approach to media and identified the weaknesses in its formulation. The subsequent semi-structured in-depth interviews probed the practices and perceptions of male and female journalists and editors in relation to the degree of change in gendered representation in the news. This study finds that the editorial gender policy at the Times of Zambia has not had any significant impact on the journalistic practices and it probed the reason for this lack of effectiveness. It argues that this can be partially attributed to the orientation of the policy within a liberal feminist paradigm which neglects the internal and external factors that influence the representation of women and men in news production. Further, this position ignores the societal structures and power relations which impact, albeit unintentional, on the treatment of news. Inter-organisational factors such as profit maximisation, political interference, the use of news values and news beats are identified as leading to the exclusion of representations of women in hard news. At an intra-organisational level, lack of importance attached to the policy by senior staff and their attitudes to news production in general have meant that the policy was not enacted or ensured in any meaningful way. The study also established that the patriarchal values that characterise Zambian society influence journalists ' and editors' treatment of news, thus making the implementation of the policy ineffective. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Malaria continues to be an enormous health-threat in the developing world and the emergence of drug resistance has further compounded the problem. The parasite-specific enzyme, 1-deoxY-D-xylulose-S-phosphate reductoisomerase (DXR), has recently been validated as a promising antimalarial drug target. The present study comprises a combination of synthetic, physical organic, computer modelling and bioassay techniques directed towards the development of novel DXR inhibitors. A range of 2-heteroarylamino-2-oxoethyl- and 2- heteroarylamino-2-oxopropyl phosphonate esters and their corresponding phosphonic acid salts have been synthesised as analogues of the highly active DXR inhibitor, fosmidomycin. Treatment of the heteroarylamino precursors with chloroacetyl chloride or chloropropionyl chloride afforded chloroamide intermediates, Arbuzov reactions of which led to the corresponding diethyl phosphonate esters. Hydrolysis of the esters has been effected using bromotrimethylsilane. Twenty-four new compounds have been prepared and fully characterised using elemental (HRMS or combustion) and spectroscopic (1- and 2-D NMR and IR) analysis. A 31p NMR kinetic study has been carried out on the two-step silylation reaction involved in the hydrolysis of the phosphonate esters and has provided activation parameters for the reaction. The kinetic analysis was refined using a computational method to give an improved fit with the experimental data. Saturation transfer difference (STD) NMR analysis, computer-simulated docking and enzyme inhibition assays have been used to evaluate the enzyme-binding and -inhibition potential of the synthesised ligands. Minimal to moderate inhibitory activity has been observed and several structure-activity relationships have been identified. In silica exploration of the DXR active site has revealed an additional binding pocket and information on the topology of the active site has led to the de novo design of a new series of potential ligands. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Since the study on the Port Alfred/Kenton-on-Sea/Boknes linefishery by Hecht and Tilney (1989) there have been substantive changes to the linefish management environment in South Africa. Using the Port Alfred linefishery as a model, the aim of this study was to evaluate the effectiveness of the linefish management regulations that were implemented by Marine and Coastal Management (MCM) since 1992, and to assess the behaviour and 'status' of the fishery in response to these changes. Changes to both the licensing structure and catch regulations have had a significant effect on the functioning of many aspects of the Port Alfred linefishery (fishing effort, catch composition, cpue) as well as on the structure of the fishery and its socio-economic profile. Overall commercial cpue decreased from 1985 to 1998. Since 1998 there has been a significant increase in cpue (from 2.3 Kg.fisher⁻¹ hour⁻¹ to a peak of 4.8 Kg.fisher⁻¹.hour⁻¹ in 2005. This was attributed to good catches of geelbek, particularly in 2005, 2007 and 2008 (during these years geelbek contributed an average of 35% to the total landings in comparison to a mean contribution of II % between 1985 and 2004). However, size spectra analysis suggests that the increase in overall cpue since 1998 misrepresents the actual status of the fishery. If geelbek is excluded from the analysis on the grounds that it is the only species in the fishery that is highly migratory, susceptible to recruitment fluctuations and it does not contribute to the catches on a year round basis, then the results suggest that the fishery is still in a declining phase despite the 80% reduction in commercial effort and numerous stricter catch regulations (e.g. size/bag limits). Furthermore, the cpue of silver kob, which has been the "mainstay" species of the fishery, has consistently declined over the last 23 year period (from 1.69 Kg.fisher⁻1 .hour1 in 1986 to 0.86 Kg.fisher⁻1.hour⁻1in 2007). The substantial reduction in commercial effort in the fishery from 33 vessels in 2001 to 13 in 2002 resulted in a shift from commercial to recreational fishing. The number of active commercial vessels in Port Alfred alone decreased from 29 in 1989 (Hecht 1993) to four in 2008. During the same timeframe, the number of regularly active recreational vessels had almost doubled (16 in 1989 to 26 in 2008). Despite the greater number of recreational boats in the fishery they only landed approximately half the average yearly tonnage of the commercial vessels (21,5 and 44,7 tonnes,annum-I , respectively) between 2006 and 2008, This was ascribed to the differences in catch regulations for the two sectors, Furthermore, it was speculated that increasing operating costs and narrowing profit margins have contributed to lower levels of compliance in both the commercial and recreational sectors since 2006, For example, 16% of silver kob landed during 2006-08 were under the minimum size, Despite the changes made to the regulations since 1998 and the 60,6% reduction In legislated commercial effort in the fishery between 2001 and 2002 it was concluded that the fishery has continued to decline, Except for the good recruitment of geelbek (which may be due to regulatory changes made in 1992) the changes in the management environment have had no measurable positive effect on this fishery, It is recommended that commercial effort should not be allowed to increase beyond the current number of active boats, that there should be an area restriction on all commerciallinefish vessels, that the current recreational bag limit for silver kob should be re-assessed, there should also be a concerted and nationally funded effort to educate recreational anglers about the merits of catch and release, and the frequency of catch inspections of both sectors should be increased, , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The study sets out to examine the television coverage of the 2002 presidential campaign in Zimbabwe by examining the extent to which the Zimbabwe Broadcasting Corporation fulfilled the mandate of public service broadcasting. The primary objective of this study is to assess how ZBC television newscasts mediated pluralistic politics in the coverage of the country's presidential election campaign, in line with the normative public sphere principles. The thesis comprises seven chapters organized, first, with an introductory chapter, which provides the general background of the study. The chapter offers the rationale for the focus on TV rather than other media fomls . There are two theoretical and contextual chapters in which the use of both qualitative and quantitative methods is explained and findings are presented. Finally, the conclusion offers recommendations about the form broadcasting might take to fulfil a public service mandate and these include the strengthening of the public service broadcasting model along normative public sphere principles. The findings of the analysed election newscasts confirm that ZBC television election news was constructed in favour of ZANU PF at the expense of voices from other social and political constituencies. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The general aim of this study was to determine the experiences of a sample of terminally ill patients in using spiritually focused psychotherapy. This was a qualitative study conducted to a sample of 2 terminally ill patients from hospice in Grahamstown, South Africa. The research was conducted in 3 phases: an initial in-depth interview conducted to determine the participants' level of spirituality as well as the extent to which their terminal illnesses had affected their functioning. This was followed by a minimum of 6 spiritually focused therapy (SFT) sessions as a second phase of the research. To determine the participants' experiences of SFT, 2-3 in-depth interviews were conducted during the 3m phase of the research study. The research revealed that a belief in a higher power helps terminally ill patients cope better with their illness and that social disconnectedness is related to HIV / AIDS stigma. It also revealed that terminal illness is co-morbid with other psychiatric symptoms such as depression, evokes existential concerns, results in a change in the level of spirituality and affects the whole family. Participants blamed themselves for their illness, but found that engaging in the process of forgiveness of self and others brought about psychological healing for them. They experienced SFT as a coping resource that assisted them to deal with the fear of death as well as increased insight into the development of psychopathology and spiritual blockages. It is recommended that a comprehensive and holistic assessment during intake be undertaken so that where spiritual needs are available, therapy can be spiritually augmented to ensure that such needs/ struggles are addressed. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This research aims to open up for critical discussion the effects of the discourses employed by mental health professionals in relation to the diagnosis of BPO, with a view of questioning the discursive practices available within a South African context. This discussion will situate identified discourses in relation to the subjects and objects to which it refers in an attempt to identify and interrogate dominant discourses which circulate to oppress and discriminate against female 'others' within the mental health setting. This discussion will serve to challenge mainstream, traditional psychology by questioning the utility of deploying these concepts within a South African context as well as the effects this deployment may have. A discourse analytic methodology is employed to identify the constructions of BPO by five mental health professionals working within a government setting. The analysis aims at interrogating the broader role of the identified discourses in supporting institutions, preserving power relations and transmitting ideological practices. Ultimately the aim of the research is to open up for critical debate, through the example of psychology and psychiatry's treatment of BPO; constituted as 'other', the possibility that there may be deleterious consequences for the wholesale acceptance of traditional psychological understandings by mental health professionals working within a South African context. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This study examines the American Dollar (USD) denominated currency returns of five developing market currencies for the presence of the day-of-the-week effect. Daily data from January 1995 to February 2008 is examined, and is split into two subperiods, SP1 (1995 - 2002) and SP2 (2003 - February 2008). Currency returns are non-normally distributed across the full data set and SP1 , but tend towards normality in SP2. As such non-parametric tests are used to test the equality of the first four moments across days of the week. Tests on the first moment show that two of the currencies do not show any evidence of the day-of-the-week effect. However, evidence of the day-of-the-week effect is found in the other three currencies in SP1, although the effect disappears or weakens significantly in SP2. Little evidence of the day-of-the-week effect is found in tests on the second moment. The hypothesis of equal higher moments across currency returns is rejected for almost all of the weekday pairs for all five currencies in SP1 , but in SP2 the hypothesis of equal higher moments can only be rejected for a single pair of weekdays for one currency. This indicates the disappearance of the day-of-the-week effect across higher moments in SP2. Thus, the study finds that the day-of-the-week effect is present across the first moment and higher moments in the returns to most currencies in SP1 , but has disappeared for all five currencies in SP2. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Parental Alienation Syndrome (PAS) is a childhood disorder that arises almost exclusively in child custody disputes. Its primary manifestation is the unjustified rejection of a once-loved parent by a child due to a combination of the 'programming' parent's alienating techniques and the child's own contributions to the vilification of the targeted parent. Parental Alienation (PA) is differentiated from PAS as in the case of the former the child's rejection is justified and may be explained either by normal developmental behaviours or by child abuse that involves no form of programming. The purpose of this study is to develop a preliminary interview protocol to aid in the detection of PAS, with a special emphasis on differentiating false allegations of abuse, which usually accompany severe PAS, from true abuse. The aim of the study is to develop a protocol to enhance diagnostic clarity and facilitate appropriate custody-related recommendations. The interview protocol is based on an extensive thematic literature analysis in conjunction with existing guidelines for conducting a child custody and visitation interview. The interview protocol comprises a child and parent section, which both have their own reference tables with supporting corresponding information. The protocol 's administration instructions are outlined in a covering information page. Rigour was added to the protocol by having it assessed for clarity and accessibility by four medico-legal professionals with custody-related experience, and their opinions regarding the protocol's structure, sections, questions and reference tables were taken into consideration in the revision of the protocol. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Cosmopolitan and For Him Magazine (FHM) are, at present, both the most widely read and, therefore, the most popular "white" consumer magazines in South Africa. They both appeal to young audiences of between 18 and 34 years of age, approximately, and target middle-class, educated groups of readers. My interest in Cosmopolitan and FHM lies in their ability to influence and shape their readers' actions, values, identities and relationships, in particular with the other gender. My analysis is focused on the cover pages and the Editor's letters of six copies of each magazine, ranging from April to September 2003, providing me with a corpus of 12 cover pages and 12 Editor's letters. I adopt a critical perspective through the use of Fairclough's (1989) Critical Discourse Analysis, supported by Mills (1995) Feminist Stylistics, McLoughlin's (2000) textual analysis of cover pages and Kress & van Leeuwen's (1996) visual analysis tools. By combining these different methodologies my research falls into what is newly termed Feminist Critical Discourse Analysis (Lazar 2005). The cover page analyses used primarily McLoughlin and Kress & van Leeuwen and provides an element of pure genre analysis, while the analysis of the Editor's letters were subject to Fairclough's three inter-related stages of analysis, namely: a Description of the formal textual elements of the letters, an Interpretation which analyses the processes of text production and interpretation, and lastly an Explanation of the socio-historical context. Through an analysis of these magazines, whose interests are being served and how the readers are shaped and positioned by the magazines can be identified. My analyses revealed conflicting discourses within each magazine, however it was Cosmopolitan that revealed more tension and conflict in terms of identifying and representing women, while FHM subscribed, for the most part, uniformly to the "new lad" ideology. However, while Cosmopolitan attempted to show a forward-thinking and emancipatory view of the roles of men and women in society, both magazines covertly sustain patriarchal dominance and hegemonic masculinity. In conclusion, I reveal the need for consumers of the mass media to become more critically aware of the ideologies that are promoted through the differing tools of the media and that only through this critical awareness can any further movement towards equal relations between men and women be made. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: rhe research study investigated the factors necessary for the development of an organizational retention ;trategy for a financial organization pertaining to key equity employees. Equity employees are those employees jescribed as such in the Employment Equity Act 55 of(1998). Bussin's (2002) Total Rewards Model was used as the theoretical framework for the study. The investigation was conducted within an interpretive paradigm and employed a qualitative methodology. Thematic analysis was used in the interpretation of the three data sources gained access through the data collection process. A previously completed employee relationship audit's findings, and the data derived from nine exit interviews formed the basis for the twenty-four semi-structured individual interviews, which were conducted with a sample ofthe employees. A purposive sampling technique enabled the identification of particular employees, who were the equity participants in the study. An additional component of the Total Rewards Model, namely Talent Management was identified from an analysis of the results. Six salient factors were highlighted in the investigation. The factors identified were: A need for a short-term incentive plan, which would provide recognition above and beyond an employee's monthly salary. The need for career development opportunities. The utilization of new skills from the training initiated by the organization. The representation of women and Black people in senior management positions. The need for formal performance support. The standardization of the recruitment process, the management of unrealistic or unattainable expectations and listening to employees' concerns. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Pelargonium reniforme is currently divided into two subspecies, P. reniforme subsp. reniforme and P. reniforme subsp. velutinum. The species falls into section Reniformia along with the closely-related P. sidoides. Observations of the section showed some discrepancies in the current taxonomy; mainly floral variation that was not recorded in the descriptions of the subspecies of P. reniforme, particularly the differences in hypanthium lengths. Patterns of variability were analysed using both morphometrics and inter simple sequence repeat (ISSR) data for P. reniforme (both subspecies), and P. sidoides. Results showed no support for the current subspecific division of P. reniforme but also no support for the current status of P. sidoides as a separate species. However, both morphometric and ISSR data show some evidence for the existence of two distinctly separate groups within P. reniforl1le subsp. velutinum as two distinct types have been recognized: those with bright pink flowers with long tubes (up to 70mm), and those with pale pink flowers with shorter tubes (as little as 8mm). These two forms have been found in a single population (Grahamstown), where they occur sympatrically, as well as in monomorphic populations. Analyses of the processes thought to be responsible for the observed patterns were conducted on the Grahamstown population. Observations of pollinators suggest that long-tongued insects (Butterflies, Nemestrinid flies) pollinate the long-tubed flowers and short-tongued insects (Bombyliid flies, long-tongued bees) pollinate short-tubed flowers. However, analysis of selection gradients in the population, indicate no directional selection is occurring for hypanthium lengths. The results of this thesis show that selection is occurring within Pelargonium reniforme, but at this time, selection is not strongly directional and floral differences are maintained, even when floral forms occur sympatrically. It is suggested that a review of the taxonomy be undertaken as well as additional pollination and selection studies to confirm suspected taxonomic groupings and relationships between the floral forms respectively. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in
