- Description: Societal trends have changed more in the last decade than they have in the last century. This is particularly prevalent in the education environment. Concepts such as Lifelong Learning (the continued learning/educating of an individual throughout his/her lifetime), New Competencies (technology that is now part of almost every skill in the workplace) and Telecommuting (more people working from home rather than traditional offices) have become common-place today (Twigg, 1996, pp. 1-2). Education delivery needs to provide for these societal changes in order to ensure competent individuals pass on to the next level of education and ultimately to the work force. With key trends in technology such as Digitization, Maturation and Disintermediation becoming common in the workplace, education delivery must address the ―Digital Divide. (Twigg, 1996, pp. 2-3). Historically, schools in South Africa have used traditional teaching methods that have stayed the same for the last century. Educational institutions in South Africa, in particular, the previously disadvantaged schools of the Eastern Cape, face various challenges such as the dwindling ability to collect school fees from parents of scholars and declining financial support from the government. In Chapter Seven of the Draft White Paper on e-Education, which was gazetted on 26 August, 2004, the DoE, as part of its implementation strategies, urged the private sector to respond by implementing ICT initiatives nationwide. Phase 1 of the strategy advocated that ―Institutions are connected, access the internet and communicate electronically. (Department of Education, 2004, pp. 37-40). This dissertation shows that it is feasible to create a communications’ network among South African schools. It is believed that such a network can add great value to the education system in South Africa. The potential for this network to address the gap in the Digital Divide is enormous. This dissertation examines various ICT communications’ technologies and isolates wireless communications’ technology as best suited for this purpose, due to the speeds offered by the technology and the cost structure associated with it. A case study examines a pilot installation of the network and endeavours to prove the concept.

- Description: The study was undertaken as the first cycle of an action research project. It presents a case study that explores the potential of the combined use of self-, peer-, and tutor-driven assessment in enhancing students’ learning in a professionally orientated postgraduate media management course. The study also explores how such a process can contribute to students developing the skills and dispositions required by autonomous learners and professionals. In approaching these questions the study draws directly on students’ own accounts of their experiences and contrasts these accounts with the growing body of literature on participative assessment in higher education that has emerged over the past decade. The study begins by exploring how action research can aid in the development of valuable insights into educational practice. It draws on educational theorists’ use of Habermas’s (1971, 1972 and 1974 in Grundy, 1987: 8) theory of knowledge constitutive interests in developing a conceptual framework against which assessment practice can be understood and argues against instrumental approaches to assessment. Set against a background of outcomes-based education, the study presents an argument for privileging the role of assessment in promoting learning above its other function. It contends that this function is undermined if students are excluded from direct involvement in assessment practice. Informed by research into participative assessment, the study presents a thick description of a particular approach used during the action research cycle and explores how students experienced this process. The findings of the study support theories favouring the involvement of students in their own assessment and suggest that such processes can contribute to meeting students’ present and future learning needs.

- Description: The Southern African Development Community (SADC) declared a Free Trade Area on 17 August 2008. The Free Trade Area is the ultimate objective of the Trade Protocol on trade cooperation in SADC, signed in 1996. The Protocol is supported and complemented by the ambitious Regional Indicative Strategic Development Plan (RISDP). The idea behind the SADC Trade Protocol was to counter the developmental challenges facing SADC member states and to improve the productive and trade capacity of SADC countries. The implementation of the SADC Free Trade Area has been guided by the WTO/GATT regulatory framework on regional trade agreements, particularly GATT Article XXIV, the Understanding on the Interpretation of GATT Article XXIV, as well as the Decision on Differential and More Favourable Treatment, Reciprocity and Fuller Participation of Developing Countries (Enabling Clause). This research seeks to analyse the SADC Trade Protocol's provisions and the implementation of such provisions. To facilitate an understanding of factors that affect the implementation of the SADC Trade Protocol, SADC's institutional and operational framework is discussed from a legal-historical perspective. The provisions of the Trade Protocol are analysed for compliance with WTO/GA TT rules as well as for applicability within the SADC context. The provisions of the WTO/GA TT regulatory framework on regional trade agreements are also analysed with a view to determining whether they are applicable in developing country situations such as SADC. The Free Trade Area is seen as the first step towards regional economic integration in the region and is to be followed by a Customs Union, a Common Market and then eventually an Economic Community with its own central bank and regional currency. It is envisaged that the region will proceed through all these traditional theoretical phases of economic integration between 2008 and 2018. The implementation of the Trade Protocol has been beset with institutional, administrative and infrastructural challenges which pose obstacles to the attainment of the other stages of economic integration in the time frames prescribed in the RISDP. These challenges are assessed for impact on the regional economic integration of SADC by evaluating the progress towards implementing the Trade Protocol provisions and the implementation of measures taken towards the launch of the Free Trade Area. Emerging issues are also identified and analysed for their effect on the Free Trade Area and the general economic agenda of SADC. Of particular note is the Economic Partnership Agreements (EPAs) being negotiated with the European Union where SADC countries are negotiating in four different configurations. An analysis of this EPA situation reveals that it compounds a pre-existing problem: that of overlapping membership of regional trade agreements. Prior to the EPAs and the intensified drive towards the creation of the Customs Union, there was largely no need to rationalise the overlap in regional trade agreement memberships, but it is now a matter of urgency. The overlap in membership has complicated EPA negotiations and places serious doubts on the prospects of complete regional integration in SADC.This research concludes with observations on South Africa's complicated relationship with her SADC neighbours. South Africa's trade policies, as regards both the SADC region and the world, are discussed. Because of its political and economic dominance, South Africa's policies have a ripple effect on the rest of SADC; hence the need for South Africa to be vigilant in formulating and implementing its trade policies.

- Description: Despite high rates of unemployment in South Africa, there is little consensus about its origins and solutions to the problem. Job search (how and when people search for work)is one aspect of the unemployment problem. Job search is shown to be a complex process strongly linked to the endogenous structure of the labour market. The flaws in traditional methods (theoretical and measurement) highlight this. Using data from a tailor-made survey in Duncan Village (a peri-urban area in Buffalo City, South Africa) the research examines factors that influence the effectiveness of job search. The results show that mode of search (how people look for work) is used as a signal by employers. Degrees of success are stratified amongst searchers using either ‘word of mouth’, place-to-place or formal modes of search. The thesis provides a method-test to reveal a complex body of evidence that has yet to be fully explored by practitioners in this field.

- Description: The syntheses and characterization of 2,3-octakis-(3-pyridyloxyphthalocyaninato) indium(III) and quaternized 2,3-octakis-(3-pyridyloxyphthalocyaninato) indium(III) are described. The ground state electronic absorption spectra, photophysics and photochemistry of both dyes in DMSO as well as that of the quaternized compound in aqueous solution are also presented. A comparison of the photophysical and photochemical parameters of the two dyes revealed that quaternized 2,3-octakis-(3-pyridyloxyphthalocyaninato) indium(III) was a better photosensitizer than its unquaternized counterpart. The quantum yield values of fluorescence (ΦF), triplet state formation (ΦT) and singlet oxygen formation (ΦΔ) for the cationic dye were found to be 0.03, 0.68 and 0.66 respectively in DMSO; these values were higher than those for 2,3-octakis-(3-pyridyloxyphthalocyaninato) indium(III), which exhibited values of 0.02, 0.66 and 0.63, respectively in DMSO. The values for the cationic dye in aq. solution were 0.02, 0.59 and 0.56 respectively, suggesting that the water-soluble quaternized 2,3-octakis-(3-pyridyloxyphthalocyaninato) indium(III) offers potential as a photosensitizer in photodynamic therapy treatment.

- Description: The introduction of Information and Communication Technologies (ICTs) for rural development in rural marginalized societies is vastly growing. However, the success of developing and deploying ICT related services is still in question as influential factors such as adaptability, scalability, sustainability, and usability have great effect on the rate of growth of ICTs in rural environments. The problem is that these ICT services should be maintained and sustained by the targeted communities. The main cause for rural marginalization is the fact that some communities situated in rural settings are educationally challenged and computer illiterate or semiliterate in comparison with urban communities. An ICT for development (ICT4D) intervention in the form of an e-Commerce platform that targets the social and economic growth of rural marginalized communities has been developed and field tested at Dwesa, a rural community located on the Wild Coast of the former homeland of Transkei in the Eastern Cape Province. The e-Commerce platform is known as “buy at Dwesa” and can be visited at this URL, http://www.dwesa.com. The aim of the e-Commerce platform is to motivate small entrepreneurs in rural areas to market their products and themselves to the global market as they lack the skills and resources for marketing their art and crafts. Virtual stores are created for a small group of entrepreneurs who will maintain and sustain the stores on their own. These entrepreneurs are often elderly women with limited education and little to no computer literacy - meaning that sustaining the stores may prove difficult for them. In this research we discuss the re-design and re-development of the virtual shop-owner interfaces of the e-Commerce platform to make them more culturally and linguistically localized. The virtual shops allow shop-owners to upload their artifacts to advertise and sell on the customer’s end of the e-Commerce platform. For multilingual and multicultural communities, adoption of the software interfaces to the user’s cultural and linguistic needs and modes of expression is important as failure to do so may reduce the level of benefits of e-Commerce initiatives.

For multilingual and multicultural communities, adoption of the software interfaces to the user’s cultural and linguistic needs and modes of expression is important as failure to do so may reduce the level of benefits of e-Commerce initiatives.

- Description: The article presents a model for formulating and planning treatment for post-traumatic stress disorder (PTSD) in South Africa derived from the existing literature and in conjunction with a review of a series of studies of cases treated using the guidelines of Ehlers and Clark's cognitive therapy. It is argued that the construction of psychotherapies (or even components of psychotherapy) for PTSD in terms of traditional categories ("psychodynamic", "cognitive-behavioural", "narrative" etc.) is misleading and unhelpful. Instead, superordinate concepts derived from thinking about evidence-based practice provide a more grounded focus on the practical issues faced by therapists treating PTSD. These concepts, which include competences and metcacompetences, therapist responsiveness, stages of therapy and case formulation, provide a basis for a genuinely integrative approach. The proposed model suggests seven broad areas of clinical focus for work with PTSD which can be arranged at three levels of priority: level 1 crisis intervention and stabilization; level 2 promoting engagement with treatment, and level 3 selection, sequencing and timing of active treatment interventions. Material from the case series is used to illustrate the application of the model.

- Description: Since the 1970s, two distinct leadership styles have been recognised in the fields of business and organisational research - transactional and transformational leadership. Transactional leadership is seen to resemble managerial-type leadership where followers fulfil their duties in return for rewards that satisfy their self-interest, such as pay or promotion. Transformational leadership, as the label suggests, is leadership that is seen to transform followers from their everyday selves to their better selves (Yukl 1998). Transformational leaders motivate followers by appealing to their higher-order needs, offering incentives for compliance such as feelings of personal empowerment, a sense of moral self-actualisation and an emphasis on the individual's contribution to the community at large (Harvey 2004). These leaders have been observed to emerge and thrive within contexts fraught with socio-political and economic turbulence, where they maximise the uncertainty of the environment to instigate change. Transformational leaders are seen to be especially adept at using discourse to foster strong, persuasive interpersonal relations with their followers. This research reports on, particularly, the interpersonal dimension of Clem Sunter's transformational discourse; he being a prominent South African scenario planner and business leader. It is essentially a qualitative study that describes Sunter's discourse in three of his texts written in 1996. The end to Apartheid in 1994 and transition from White to Black governance meant that the socio-political climate of 1996 South Africa was conducive to the rise of a transformational leader like Sunter. Although the country was, ostensibly, a democracy in 1996, much social transformation was still needed at the time Sunter produced his texts. The analysis are grounded mainly in Systemic Functional Linguistics, specifically APPRAISAL theory and, to some extent, Critical Discourse Analysis theory. However, the analyses do not follow a classic CDA analysis approach, but draw rather from more recent CDA work (cf. Fairclough 2003), such as the analysis of value assumption types within the texts. This analysis clearly demonstrates that Sunter's discourse is congruent 11 with the principal insights of transformational leadership. More than this, it is argued that these findings suggest a close link between transformational leadership and the goals of the latest social order of new capitalism, a link not made in the relevant research to date. The analysis of modes of operation of ideology in the texts (cf. Thompson 1990), also deriving from CDA, reinforces this, indicating that Sunter's transformational discourse promotes and maintains the kinds of power inequalities that underpin new capitalism. The APPRAISAL analysis of Affect choices in the text reveals a high frequency of disquiet, i.e. Sunter's discourse is seen to generate feelings of insecurity and fear. This feature, interestingly, is completely inconsistent with current transformational leadership theory, but would have been an effective motivational technique given the instability of the South African socio-political context in 1996. In addition, the APPRAISAL analysis of Judgement reveals that Sunter evokes high levels of tenacity and appeals to readers' morality, ethics and feelings of group-efficacy - all higher-order needs. The argument here too is that the socio-political context enabled Sunter to stimulate disquiet and tenacity in an effective configuration to mobilise change in his reader and promote the goals of new capitalism. The thesis concludes with a reflection on the limitations of the study and makes various recommendations for future research.

- Description: The African Union’s prioritisation of inland fisheries as an investment area for poverty alleviation and regional economic development will require the development of management plans. These should be based on sound knowledge of the social dynamics of the resource users. In South Africa the social dynamics of resource users of inland fisheries have never been assessed. The purpose of this study was to assess the human dimensions of the anglers utilising the fishery in Lake Gariep, South Africa’s largest impoundment. The study was based on 357 first-time interviews conducted on the lakeshore between October 2006 and December 2007. Anglers were categorised as recreational (39%) or subsistence (61%) based on their residency, occupation, primary motivation for angling, mode of transport and gear use. Subsistence anglers were local (99%), residing within 10 km of the place where they were interviewed, while recreational anglers included both local resident and non-resident members. The racial composition of anglers was dependent on user group and differed significantly (p ≤ 0.05) from the demographic composition of the regional population. Recreational anglers were predominantly White (≥ 60% of interviews) and Coloured (≥ 25%), while 84% of subsistence anglers were Coloured and 16% Black African. Most recreational anglers had permanent employment or were pensioners while <30% of subsistence anglers were permanently employed. Most recreational users (82%) accessed the lake with their own vehicle while subsistence anglers mainly walked (63%) or used a bicycle (28%). Recreational interviewees either consumed (59%), sold (11%), gave away (10%) or released (20%) some of their catch. Subsistence anglers either ate their catch (53%) and/or sold (41%) their catch. Within the subsistence sector no anglers released fish after capture or gave some of the catch away. We conclude that this inland fishery contributes to the livelihood of the rural poor who use the lake on a subsistence basis and that recreational-angler based tourism may contribute to increased income and employment opportunities through related service industries.

- Description: A large sportfishery that targets both smallmouth (Labeobarbus aeneus) and largemouth (Labeobarbus kimberleyensis) yellowfish exists in South Africa. Both species have high conservation priority, and no assessments documenting the effect of angling on L. aeneus and L. kimberleyensis have been undertaken. The overall aim of this study was to provide an assessment of the impact of angling on L. aeneus and L. kimberleyensis. The specific objectives of this study were to characterise the sectors utilising Lake Gariep, document catch, effort and total catch for the fishery as well as the locality specific biology of L. aeneus and L. kimberleyensis. The study was undertaken on Lake Gariep, South Africa's largest impoundment, situated on the Orange River system in central South Africa. Subsistence fishers were the dominant user group, constituting 60 % of the fishery, the remainder constituted recreational anglers. Angler catches were dominated by carp (Cyprinus carpio; 74 %), followed by mudfish (Labeo capensis; 13 %) and smallmouth yellowfish (8 %). Catches of largemouth yellowfish contributed < 0.5 % to the total catch. The relative abundance of species by weight differed by area (χ² test of independence: χ² = 182, df = 4, p ≤ 0.05). On any sampling day time fished was the best predictor for differences in probability of capture (PC) (Wald X²(1) = 7.169, p = 0.007). The probability of capturing L. aeneus differed significantly between month (Wald X²(5) = 20.690, p = 0.000) and region (Wald X²(3) = 46.755, p = 0.000). The single best predictor of differences in log abundance and non-zero CPUE was region (Factorial ANOVA p ≤ 0.05). Mean CPUE ranged from 0.21 ± 0.06 kg. man⁻¹.hr⁻¹ to 0.82 ± 0.11 kg. man⁻¹.hr⁻¹ in the OV region and 0.42 ± 0.10 kg. man⁻¹.hr⁻¹ to 1.17 ± 0.24 kg. man⁻¹.hr⁻¹ in the GD region. Angler effort was higher in OV than in GD and ranged from 17 ± 3 anglers/day to 45 ± 9 anglers/day and 6 ± 1 anglers/day to 41 ± 8 anglers/day, respectively. Total catch was higher in the GD 46.0 [95 % CI = 15:102.6] t. period⁻¹ than the OV region 40.0 [95 % CI = 13.9:89.6] t. period⁻¹. The total catch from the Lake Gariep fishery between March and December 2007 was estimated to be 86.0 [95 % CI = 40.4:154.8] t. period⁻¹. Age and growth was determined using whole otoliths. The growth of L. aeneus was best described by the von Bertalanffy growth model as Lt = 481.80 (1- e⁻°·²²⁽t⁺°·⁶¹⁾). Gonadal development for L. aeneus was seasonal, with the gonadosomatic index peaking in January, revealing a distinct spawning season. The length at 50 % maturity for female L. aeneus was attained at a fork length of 354.7 mm. Natural mortality (M) was estimated at 0.55 year⁻¹. The growth of L. kimberleyensis was described by the von Bertalanffy growth model as Lt = 763.22 (1- e⁻°·¹¹⁽t⁺°·⁶³⁾). Only 6 mature female and 15 mature male L. kimberleyensis were recorded during the study period. The smallest mature female was a 390 mm FL stage four female and the earliest recorded mature male was a 337 mm FL, ripe running male. Natural mortality (M) was estimated at 0.08 year⁻¹ for L. kimberleyensis. Per recruit analysis indicated that current fishing mortality reduces the L. aeneus spawner biomass by 7 %, which is considered negligible. Labeobarbus kimberleyensis forms an insignificant proportion of anglers catches and stock status is currently considered pristine.

- Description: Using a pooled panel data set from nine developing countries within the SADC region from 1992 to 2004, this paper empirically examines; firstly, the relationship between stock market development and long-term economic growth, and secondly, the macroeconomic determinants of stock market development, particularly market capitalisation as a percentage of GDP. The results suggest that there is a strong link between stock market development and economic growth, particularly through the liquidity provided by the market. The evidence obtained lends support to the view that a well-developed and functioning stock market can boost economic growth by enhancing faster capital accumulation and allowing for better resource allocation, particularly in developing countries. In terms of the macroeconomic determinants of stock market development, the results support those of Garcia and Liu (1999), in that we found the indicators of financial intermediary development, the value of shares traded as a percentage of GDP and the macroeconomic instability variable to be important determinants of stock market development.

- 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: Much research work has assessed the construction process and discovered that the process is ineffective and besieged with problems. Analysis of these problems has shown that a major part of them are related to the state and workings of the supply chains. Prior research justifies that waste and problems in construction supply chains are extensively present and persistent. This anomaly may be ascribed to the nature of the industry. Horizontal integration that is common place in the construction industry tends to fragment the supply chain, resulting in an unstable production environment occasioned by high unpredictability, much rework, low profits and eventual low level of value creation in the process. Therefore, an increased level of integration of interfaces and processes has been canvassed. The purpose of supply chain management is to achieve the expected increased level of integration of the whole supply chain. Supply chain management is a concept that has flourished in the manufacturing industry through Just in Time production and logistics. Supply chain management represents an autonomous managerial tool, though still largely dominated by logistics. Supply chain management has long been advocated as a means of improving the performance of supply chains in construction. This research study reports on an investigation into the impact of supply chain management on value creation in the South African construction industry. The research discovered that collaborative working is already in the industry and contractors consider supply chain management important for project success. Here construction supply chains were approached from the relationship view point. All issues are encouraged to be viewed and resolved in the supply chain from the relationship perspective.

Prior research justifies that waste and problems in construction supply chains are extensively present and persistent. This anomaly may be ascribed to the nature of the industry. Horizontal integration that is common place in the construction industry tends to fragment the supply chain, resulting in an unstable production environment occasioned by high unpredictability, much rework, low profits and eventual low level of value creation in the process. Therefore, an increased level of integration of interfaces and processes has been canvassed. The purpose of supply chain management is to achieve the expected increased level of integration of the whole supply chain. Supply chain management is a concept that has flourished in the manufacturing industry through Just in Time production and logistics. Supply chain management represents an autonomous managerial tool, though still largely dominated by logistics. Supply chain management has long been advocated as a means of improving the performance of supply chains in construction. This research study reports on an investigation into the impact of supply chain management on value creation in the South African construction industry. The research discovered that collaborative working is already in the industry and contractors consider supply chain management important for project success. Here construction supply chains were approached from the relationship view point. All issues are encouraged to be viewed and resolved in the supply chain from the relationship perspective.

- Description: The study analysed the management of disciplinary approaches to classroom management in selected Northern Areas schools in Port Elizabeth, South Africa. The South African education system has historically promoted corporal punishment as a means of maintaining discipline. As a result corporal punishment was an integral part of schooling for most educators and learners in twentieth century South African schools (Morrel, 2001b:292). Since 1994, however, the South African government has implemented principles of equity, redress and social empowerment in broader society and education. Consequently, corporal punishment was banned in schools and new methods of managing discipline were introduced. The study followed a qualitative investigation, which is explorative, descriptive and contextual, using interviews with educators and questionnaires with learners to collect data at selected schools. The study’s aim was to investigate and explore the perceptions and experiences of learners and educators regarding discipline and to make recommendations regarding proactive, positive disciplinary approaches so as to guide educators to facilitate learners towards self-discipline. However, it was discovered that educators were unable to facilitate self-discipline or guide learners as they themselves had not learnt to practise and demonstrate the values and principles of self-discipline. This study thus has as its intention to challenge educators to review and refocus their ways, motives and expected outcomes as they demonstrate and exercise discipline.

- Description: This research study addressed the importance of succession planning for the organisations’ survival, which depends on the continuous supply of competent, experienced and well trained managers. It addresses the problem of determining the strategies that can be used by SARS Enforcement Port Elizabeth to manage succession planning effectively. To achieve this objective a comprehensive literature study was performed to determine the views on various succession planning models. The literature review serves as a model in the development of a guideline for SARS Enforcement Port Elizabeth management to manage succession planning. An interview was conducted with the Human Resource Manager and Middle management from the various departments who were requested to complete a questionnaire in order to determine the current practices of succession planning. The questionnaire was developed in accordance with the findings from the research. A pilot study was conducted to evaluate the relevance of the study to the problem questions and to evaluate whether the questionnaire will be easily understood. The answers of the respondents were analysed and compared to the findings of the literature study. The information obtained from the literature study and from the respondents resulted in various recommendations and conclusions.

- Description: The syntheses and spectral, photophysical and photochemical properties of some zinc phthalocyanine derivatives – {2, (3)-tetra(quinoxalinyl)phthalocyaninato zinc(II), (β-ZnPc) and 1, (4)-tetra(quinoxalinyl)phthalocyaninato zinc(II), (α-ZnPc)} – are presented. The β-substituted complex is more fluorescent and exhibits lower tendencies to undergo intersystem crossing than its α-substituted counterpart, as judged by the former's higher fluorescence quantum yield (ΦF) and lower triplet quantum yield (ΦT) than the latter's in three solvents (DMSO, DMF and toluene). Singlet oxygen quantum yield (ΦΔ) values show the same trends as ΦT values. The differences in the spectral and photophysical properties of α-ZnPc and β-ZnPc are partly attributed to greater molecular distortions in the former. Studies of the interaction of the triplet states of α-ZnPc and β-ZnPc with triplet oxygen showed that α-ZnPc is more vulnerable to oxygen quenching than β-ZnPc. Also, the smallest quenching rate constants were observed in DMSO, which is attributed to the higher viscosity of DMSO than DMF and toluene.
