  • Description: The history of South Africa has been shaped by the dictatorial laws of the apartheid regime which ushered an order of domination and segregation, ostensibly to perpetuate social inequality along racial lines. In the process the white minority intended to stifle the potential of the black communities and render them subservient and unable to question or stand against white domination. To this effect the white minority instituted discriminatory laws such as The Native Land Act of 1913, among others, in a bid to give impetus to the dispossession of black communities of their land. The dispossessed people were eventually forcefully removed from their land and posted to the middle of nowhere, at the so-called Ciskei and Transkei territories. In these homelands, as these states were called, the black South Africans started to feel the pinch of apartheid more. The worst of all, these people were impoverished since they had no jobs. It is only after the emergence of the democratic dispensation, in 1994, that the transformative action was taken even though it failed to deliver as expected. In the process, the Department of Rural Development and Land Reform was established with a mission to transform and redress the evils of the past by either giving the dispossessed back their land, alternative land or financial compensation, among other arrangements. However, since it was difficult to give people back their land, the most popular option became financial compensation. This choice, it has been argued, was influenced by the high levels of poverty, high unemployment rate, low rural household incomes and poor levels of education – instances which may have led to the beneficiaries attaching little or no value towards land ownership and other possible means of land restitution. As such, ii the majority of the community thought that financial compensation would lead to sustainable livelihood and would, therefore, not allow such opportunity to slip off their hands. However, more than two decades after the emergence of the democratic dispensation, the popular financial compensation has not yielded the expected results. Yet there is a Cata community which, being among the first members of the society to successfully claim for land restitution opted for land restoration and financial compensation award was given to claimants to pay for houses that were demolished during the betterment process. Out of the award, the Cata community took a calculated risk and invested 50% of the compensation money towards the development and improving the livelihood of the Cata community. This being the case, the study sought to explore to what extent the restitution programme (with the financial compensation option) could succeed in improving the livelihoods of the Cata community. In a way, while this statement is the main objective of the study, it also satisfies the key question of the study. It will ensure that the Cata community, in their attempt to lead sustainable livelihoods, will become creative and ensure that people have good paying jobs, they budget and rationalise before using money; and that they are even prepared to take calculated risks in order to succeed, just as the Cata communities have done. No doubt this would ensure that every member of the society enjoys and is regaled by the fruits and transformative actions of the new democratic dispensation. Qualitative research methodology has been selected to conduct research of this study because it requires a researcher to dig deep to the research problems and give out rich research findings with insight because community experiences can only be understood qualitatively not through the statistics. The main findings of this study among others are that financial compensation should be linked with iii development in order to sustain livelihoods of the rural poor as the case has been with Cata community. A number of communities who opted financial compensation did not lead a sustainable livelihood instead they either became poorer or fell victims of poverty because they fail to use their financial compensation award wisely.

  • Description: Biochar is being promoted as an amendment to improve soil properties, crop productivity, and carbon sequestration. In Africa, biochar adoption is hindered by production systems which include technology and feedstocks availability. However, little research has been published on the influence of biochar incorporation on soil chemical properties and early crop establishment. The aim of this study was to characterize biochar from cattle, goat, sheep and poultry kraal manures and their effect on soil properties and crop growth. This was guided by the following specific objectives, (i) to explore the mixed-farming system of Raymond Mhlaba Municipality on availability and utilization of livestock kraal manures (ii) to characterize biochar samples produced from cattle, goat, sheep and poultry kraal manures (iii) to determine the nutrient release patterns of biochars amended in a degraded soil (iv) to determine the effectiveness of converting manure to biochar and cattle manure on maize early development and, (v) to determine the effects of biochar type and application rate on early maize development. The farming system was surveyed to identify quantities of livestock manure, its availability and utilization for soil fertility amendment in cropping in the Raymond Mhlaba Municipality. The emerging results across all the villages revealed that, the mean livestock numbers were, 9.24±8.21 sheep, 9.37±8.15 goats, 7.95±7.66 cattle and 9.02±9.47 chickens. The findings revealed that 94 (82.4percent) of the respondents had access to cropland allocations in the form of outfields and homegardens. However, only 55 (48.2percent) of the respondents were currently cropping their fields. Maize was the most common crop grown followed by butternuts and potatoes. The application of manure by the respondents currently cropping their lands was only 40 (35.1percent) and the quantities used ranged from 210-1450 kg ha-1. The results further showed that the estimated total manure production was 2.9 t year-1, 0.82 t year-1, 0.04 t year-1, and 0.8 t year-1 from cattle, goats, chicken, and sheeps respectively. Drum retort method of slow pyrolysis at a temperature of 400°C was used to produce biochar from cattle, goat, sheep and poultry manure feedstocks. The biochar yields were 63percent, 72percent, 61percent and 83percent on a weight basis for the different feedstocks. The chemical properties of the biochar were significantly different from those of the manure from which they were made. Biochars that were high in Ca and K such as poultry manure biochar and sheep manure biochar indicated higher pH and electrical conductivity values. For instance, sheep manure biochar was (8.1 mS cm-1) and poultry manure biochar was (9.2 mS cm-1). The scanning electron microscopy (SEM) revealed that, the biochars had porous structures ranging from 1.23um to 5.23um in diameter which are important for water conductance and holding capacity. The target soil carbon level to determine the effects of biochar soil incorporation was 2percent and the soil had 0.7percent. Therefore, it was treated with four livestock manure biochars at application rates of 0; 53.2 t ha-1 (CMB); 48.1 t ha-1 (GMB); 50.7 t ha-1 (SMB); and 40.2 t ha-1 (PMB) based on their carbon content to supplement the soil carbon difference. The effect on soil pH was such that SMB increased to 6.44, PMB (6.45), CMB (6.54), and GMB (6.53) relative to the control which did not show any changes. An increase was also observed on Olsen P concentrations (mg P kg-1) which varied with biochar treatments: PMB (6.22), GMB (6.37), SMB (6.44) and CMB (6.44) and were significantly higher than the control. Ammonium-N(NH4+) concentrations (mg NH4+-N) were increased in biochar treatments but, no significant differences were obtained with sampling time. SMB released 7.95 mg kg-1, CMB 7.50 mg kg- 1, PMB 7.46 mg kg-1 and GMB 7.05 mg kg-1, compared to the control 3.23 mg kg-1. Maize growth in soil sampled from farmers fields in cultivation and abandoned treated with biochar without application of inorganic fertilizer did not differ with control (soil only) treatments. However, maize growth in soil treated with biochar and inorganic fertilizer was comparative to manure treatments. This resulted in a follow up study to elucidate the effects of biochar alone and was carried out with cattle, goat, sheep and poultry biochars at five application rates (0, 100, 200, 300, and 400 kg C ha-1) applied to a sandy loam and a clayey loam soil of the Oakleaf and Tukulu soil forms respectively. Post-harvest soil pH, electrical conductivity and Olsen P showed improvements in biochar treatments relative to the control. Improvements in the chemical parameters and plant growth increased simultaneously with biochar application rate. Maize growth was not affected by biochar application at different rates.

  • Description: Immigrants, in whatever country they settle, have always been involved in entrepreneurial activities mainly for survival, remittance and other purposes. Globally, immigrant entrepreneurship has significantly contributed to the economy of host nations. The aim of this research study is to investigate the business strategies, challenges and socio-economic contribution of immigrant entrepreneurship in the Buffalo City Metropolitan Municipal (BCMM) area, Eastern Cape, South Africa. This study builds upon fieldwork undertaken within the Buffalo City Metropolitan Municipal area situated in the Eastern Cape Province of South Africa. A Case Study research design was utilised, and it encompassed three kinds of data collection methods – indepth interviews, focus groups and direct observation. The key finding of this study indicated that as a consequence of the challenges they encounter, immigrant entrepreneurs in the Buffalo City Metropolitan Municipal area had devised different business strategies to ensure that their businesses remain afloat and profitable. Another key finding of the study is that immigrant entrepreneurs in the BCMM Area make significant socio-economic contributions to their host communities. In addition to other positive contributions, immigrant entrepreneurs add to the revitalization of neighbourhoods and provide employment to their respective communities.

  • Description: Exploring student drinking, this research provides an in-depth investigation into how “beer goggles” is constructed discursively and what implications that has within the South African university context. In doing so, research attempted to: 1) map out the discursive resources operating in the empirical research literature, public domain texts and individual talk; 2) identify the subject positions and action orientation of these constructions, and 3) to establish what gendered subjectivities are reproduced within that framework. With a qualitative and social constructionist background, this study utilised a Foucauldian discourse analytic method that included ideas from discursive research. Data collection involved five mainstream videos, three focus groups and three interviews. Along with the research literature, the videos represented the wider social constructions around “beer goggles” that are played out in the micro contexts displayed by the latter participant material. Based on their popularity on YouTube, consideration was given to videos that were the most relevant and theoretically interesting to the research project. The focus groups and interviews involved current, full time, male and female, Rhodes University students over the age of 18. Analysis revealed a common sense construction of the phenomenon that has various discursive implications. While embarrassing and sometimes out of control; “beer goggles” is constructed as a socially profitable altered state of mind that is deemed a normal and heterosexual experience in the university drinking culture. Highlighting the importance of a discursive investigation, this study provided new and alternative information that can assist further research and shed light on the debates surrounding the phenomenon. Additional research is recommended.

  • Description: The study uses domestication of technology and Cultural Studies theories to investigate how youth in three institutions of tertiary learning in Harare, Zimbabwe are accessing health-related information online using their smart phones. The study critically examines how youths deploy these digital media technologies to construct their identities in a context where social and political power is unevenly distributed. To understand these issues, the study uses a triangulated research design comprising a social survey, in-depth individual interviews and field observation for data collection. Results from this data gathering showed that the use of digital media technologies differ across gender, at least in terms of the distribution of online health seeking practices between male and female youths. According to the survey results, more women tend to use their mobile phones to access health-related information. Data from the individual in-depth interviews showed that the most significant site of social change (social disruption) relates to how digital media facilitates emerging new identities (i.e. identity in the broader sense as well as health-related and sexual health identities). For both young men and young women, mobile phones are used precisely for image management, peer acceptance and the desire to define respective feminities and masculinities within their social networks. Both male and female youths assert they are able to access a variety of information online, and some of this information would not easily accessible when sought from traditional structures such as their parents. This way, youth feel that digital media technologies allow them to cultivate their own preferred identities outside the purview of parental authority and social control. Drawing on postmodern literature, such emerging identities are predicated on cultural volatility, unpredictability, decentralisation and refusal to fixation and conformity to socially constructed identities about being a youth, or being a young Zimbabwean woman or man, for example. Thus, the use of mobile phones and mobile Internet by youths in Zimbabwe to access health-related information has sociopolitical significance, because it allows young people to fashion preferred identities that resists entrenched regimes of social power. For young people in Zimbabwe, online health seeking practices precisely reflects attempt towards negotiating with and circumvent the structural limitations of either an expensive health care system or the general curiosity associated with growing up. That way, it is arguable that youth use digital media technologies to help them exercise some level of social autonomy and agency in dealing with everyday life. Individual in-depth interviews demonstrated that mobile phones and mobile Internet can thus be seen as opening up more spaces for youth to learn more about issues about growing up, sexuality and adolescents that a conservative society such as Zimbabwe traditionally consider as ‘inappropriate’ for youth consumption. They argued that the inability of parents to discuss with them issues about growing up often result in them “finding out on our own” using digital media technologies to satisfy the desire to wean themselves from what they view as arbitrary and asymmetrical social power. The study demonstrated that youth use the mobile phone to challenge the social world of adults and to show resistance to it, thereby strengthening a subculture as well as constructing an identity. However, despite the positive attributes of social capital, connectivity and personalised experience afforded by the mobile phone, the mobile phone is sometimes a source of conflict in relationships between young men and women; that is, between unmarried partners. Young women reported that their boyfriends often force them to disclose who they communicate with using their mobile phones. They also reported that their boyfriends often did some random surveillance of their social media contacts and activities. Thus, whilst one of the mobile phone’s most powerful attribute is its ability to offer personalised experience, as well as offer synchronised and unlimited access to distant connections, results from in-depth interviews showed that some unwritten expectations and norms dictated that young men closely watch their ‘girlfriends’ social media activities, including their online search activities. As a result, privacy as well as the much touted relationship between mobile phone and women’s autonomy becomes contested arenas. Even at young ages, and before marriage, women are socialised to show subservience to their partners by allowing them access to their mobile phones.

  • Description: Tridentate benzimidazole-based ligands, bis((1H-benzimidazol-2-yl)methyl)sulfide (BNSN) and bis((1H-benzimidazol-2-yl)methyl)amine (BNNN), along with dinonylnaphthalene sulfonic acid (DNNSA) as a synergist, were investigated as potential selective extractants for Ni2+ from base metals in a solvent extraction system using 2-octanol/Shellsol 2325 (8:2) as diluent and modifier. However, extraction studies show a lack of pH-metric separation of the later 3d metal ions with bis((1-octylbenzimidazol-2-yl)methyl)sulfide (BONSN) and bis((1- decylbenzimidazol-2-yl)methyl)amine (BDNNN) as extractants, but extractions occurred in the low pH range with an opportunity for back extraction. This investigation suggested that tridentate ligands (at least those of the nature investigated here) are not feasible extractants for separation of base metal ions due to their lack of stereochemical “tailor-making.”

  • Description: This qualitative study, focussing on the way in which values and valuing processes might strengthen social learning in water stewardship practices in South Africa, is located within the broader global narrative that describes the scale of human impact on our Earth systems and that is setting humanity on a trajectory that threatens to place us beyond the safe operating spaces called planetary boundaries. For humanity to live within planetary boundaries – one of which is global freshwater use –will take a new way of relating to the environment called Earth stewardship, which calls for a new ethic of responsibility towards Earth systems. It is at the local level of stewardship within a global approach to water resources management called integrated water resources management that this qualitative study is contextually bound. Two case studies, located in the catchment management forums (CMFs) of the Upper Vaal catchment of Gauteng, South Africa, are used in an exploration of the way in which values and valuing processes might strengthen social learning in water stewardship practices in South Africa. The meta-theory of critical realism is used to help explore this relationship between values, practice and social learning. The study uses document analysis, interviews and observation of selected water stewardship practices to identify held and assigned values, and valuing processes and their influence on social learning, and the framing and de-framing processes that occur in social learning oriented towards water stewardship practices. The study differentiates between held and assigned values and identifies a strong altruistic-held values tendency that characterises forum participants who practice water stewardship in the two case study sites. Most water stewardship practice, identified in the case study sites, manifests as compliance activities in the public – or forum – space, while private-sphere environmentalism is mostly left to the confines of the individual’s private household. Lastly, the CMFs seem to have the potential to provide a space for social learning that is not yet maximised. Drawing from these key findings, the study’s major recommendation is that forums that facilitate learning, either using the current CMF structure or creating new opportunities, need to be provided as a conduit for social learning and reflexivity to make the existing boundaries between private and public forms of water stewardship more porous. This social learning may expand social practice and thus strengthen social change processes that expand water stewardship practices.

  • Description: In the contemporary business environment, a plethora of retail literature exists which examine the influence of CSR on the business. However, literature that explores Corporate Social Responsibility (CSR) in the liquor retail sector has been relatively sparse. This study explored CSR in Small to Medium Enterprise (SME) liquor retail outlets in the Buffalo City Metropolitan Municipality, Eastern Cape, South Africa. The objectives of the study were to investigate the engagement of SME liquor retailers in CSR practices, to ascertain whether a relationship exists between providing employee training on responsible retailing of alcohol and CSR practices by SME liquor retailers, to investigate whether employee involvement in decision making influences CSR practices by SME liquor retailers, to ascertain whether a relationship exists between the practical actions to reduce alcohol-related harm and CSR practices by SME liquor retailers, to investigate whether SME liquor retailers do social good as an expression of CSR as well as to determine whether SME liquor retailers are influenced by stakeholders to engage in CSR initiatives. Both primary and secondary data sources were used in this study. A quantitative research design was used in conducting this research. Convenience sampling, a non-probability sampling technique, was used to select a sample of 94 from the sample frame of 123 SME liquor retailers. The survey method, by way of a self-administered questionnaire was used to collect primary data. The statistical Package for Social Sciences (SPSS) as statistical software was used to analyse data. The Chi-square test, Pearson correlation, and descriptive statistics were used to analyse data. The findings of this research revealed that Stakeholder influence, employee involvement in decision making and employee training in responsible retailing of alcohol have an influence on the CSR practices of SME liquor retailers. The study also identified the safety and practical measures that SME liquor retailers are practicing as a way of reducing alcohol related-harm. A recommendation to stakeholders, such as suppliers and government to find more strategies of influencing SME liquor retailers to practice CSR, was made. Lastly, recommendations were made to SME liquor owners and managers on how to improve their CSR practices.

  • Description: Breast cancer is a leading cause of cancer death in Africa. Hsp90 has been identified as a target for anti-cancer treatments as its inhibition results in the disruption and ubiquitin–proteasome degradation of activated oncoproteins. Currently, there are no US Food and Drug Administration approved Hsp90 inhibitor drugs and existing Hsp90 inhibitors such as geldanamycin and novobiocin are hepatotoxic and display a low affinity for Hsp90, respectively. Therefore, there is a need for the development of Hsp90 inhibitors with improved inhibitory properties. In this study twelve natural compounds bearing a quinone nucleus were screened and characterised for the modulation of Hsp90. The compounds analysed formed three series; the sargaquinoic acid (SQA), naphthoquinone, and pyrroloiminoquinone alkaloid series. Certain compounds exhibited half maximal inhibitory concentrations of between 3.32 μM and 12.4 μM, while others showed no antiproliferative activity at concentrations of up to 500 μM in the MDA-MB-231 breast adenocarcinoma cell line. Immunofluorescence and Western analyses indicated that the modulation of Hsp90 and partner proteins by SQA was more similar to that of novobiocin. Isothermal titration calorimetry analyses suggested that SQA interacted with Hsp90β with a low affinity, and saturation-transfer difference nuclear magnetic resonance confirmed that this interaction with Hsp90β occurred through the methyl moiety bound to 1, 4 benzoquinone of SQA. Pulldown assays indicated SQA disrupted the association between Hsp90 and Hop dose-dependently, more similarly to novobiocin. Immunofluorescence and Western analyses performed on naphthoquinone and pyrroloiminoquinone alkaloid compounds indicated modulation of Hsp90 and Hsp90 partner proteins by the compounds. Naphthoquinone compounds were prioritised for analysis for binding to Hsp90β over the pyrroloiminoquinone alkaloid compounds. Lapachol interacted with Hsp90β with a low affinity however; this interaction was thought to be too weak to disrupt the association of Hsp90 and Hop. The remaining naphthoquinone compounds showed no interaction with Hsp90β, thus allowing the determination of a preliminary structure-activity relationship for these compounds. To the best of our knowledge, this is the first study to describe a systematic subcellular analysis of the effects of geldanamycin and novobiocin in comparison to sargaquinoic acid and compounds of the naphthoquinone and pyrroloquinoline scaffold on Hsp90 and its partner proteins. , Microsoft� Word 2010 , Adobe Acrobat 9.54 Paper Capture Plug-in

  • Description: Suboptimal preparation for the Ironman triathlon can have detrimental effects on mental and physical condition. The purpose of this longitudinal investigation was to examine the relationship between a number of performance changes and fatigue markers during training for an Ironman as well as immediately after the event, in an attempt to better understand the effects of ultraendurance training. Eighteen athletes training for the Ironman; South Africa, 2009 were recruited for the study. Over the 6 month data collection period body mass, training load (TRIMP and Session x RPE methods), physiological responses (waking heart rate, postural dizziness, sleep ratings), changes in psychological state (profile of mood states - POMS), reported immunological responses (symptoms of illness), biochemical changes (salivary cortisol and alpha amylase) and performance (8 km submaximal running time trial (TT) and race day performance) were measured. These responses were compared to a control sample (n=15). Results show a significant increase (p<0.05) in training load (3899.4 ± 2517.8) four weeks prior to the event. Fatigue scores significantly increased (p<0.05) concurrently with this significant increase (p<0.05) in training. TT performance did not significantly (p<0.05) alter during the time course of training. It was however strongly correlated to training load (R2=0.85) and modestly related to race performance (R2=0.65). The signs and symptoms of upper respiratory tract infections (URTI) were prevalent during the training period, decreasing during the taper and race period. Large standard deviations were found within the majority of the responses. During the final two weeks of preparation, tension scores were significantly increased (p<0.05) while training load significantly decreased (p<0.05) during the final week of preparation. Cortisol increased significantly (p<0.05) immediately post race (0.507±0.15

  • Description: A range of chromone-2-carboxylic acids has been prepared by condensing suitably substituted 2-hydroxyacetophenones with diethyl oxalate. pK₂ Studies of these acids revealed that 6- or 7-methoxy substituents decreased acidity while the 6-nitro group enhanced acidity; the strongest acid was the 3-chloro derivative, the increase in acidity being attributed to steric inhibition of acid-weakening delocalisation between the carboxyl group and the chromone system. Various chromone-2-carboxamides, derived from acid chloride precursors, were converted to polysubstituted acrylamides by nucleophilic ring-opening with selected amine nucleophiles. The main fragmentation patterns exhibited by these acrylamides were elucidated using a combination of low resolution, high resolution and meta-stable peak analysis, while the effect of substituents on the simultaneous internal rotation involving the carboxamide and enamine moieties were studied using dynamic NMR spectroscopy. Rotational barriers of ca. 67.1 kJmol ̄¹ and ca. 102 kJmol ̄¹ were found for the enamine and amide rotors, respectively. Several synthetic pathways were followed to prepare a series of 2-(N,N-dialkylamino)chromones which were subjected to detailed mass spectral analysis. In addition to substituent-specific fragmentations , the 2-aminochromones appear to fragment via 3 major pathways. The effect of substituents on the internal rotation of the amino moeity was investigated by variable temperature ¹H NMR spectroscopy and the resulting DNMR data was used to calculate the rotational barriers. Examination of the data reveals that the electron-releasing 6- and 7- substituents reduce the C-NMe₂ rotational barrier to ca. 43.5 kJmol ̄¹ , while the nitro analogue has the largest rotational barrier (ca. 46.1 kJmol ̄¹) because of the electron-withdrawing effect of this substituent.

  • Description: In medical anthropology there has been a tendency to dichotomize western biomedical . healtb services, on the one hand, and traditional health care practices on the other. Much attention has been focused on the comparison between these two approaches in the hope that they might be reconciled. The problem with this approach is twofold. In the first place, it has not always acknowledged the local, historic~1, political and economic contexts in which different approaches to health care have evolved and in the second place, health care services which belong to neither the western nor traditional healing spheres and which are driven by commercial interests have been almost completely neglected because they fall outside of the basic dichotomy. Amayeza stores have been a feature of South African towns and cities for many years. They mayor may not be run by Africans, but their clientele is almost exclusively African in this region. They deal in a bewildering variety of products and remedies, from untreated herbal and animal products to pharmaceuticals specially prepared for the African market, to Dutch and Indian Remedies. These stores both reflect transfonnations in indigenous perceptions of health care and, by virtue of the choices they offer, generate change. In this empirical study three stores in the Eastern Cape are selected for detailed study - two in King William's Town, the regional capital, and one in the small town of Peddie. The approach is holistic, emphasizing the social, political and economic context, the business histories and running of each shop, and, in particular, the perceptions and choices of a sample of the customers in each case. The success of the amayeza phenomenon derives from its eclecticism and syncretism. These stores impose neither a western nor a traditional model of health care on their clients, but offer them a range of choices that reflects the complex multicultural history of their own South African society.

  • Description: The role of the queen in wax secretion and comb building was studied in the the Cape honeybee, Apis mellifera capensis (Escholtz). The percentage of bees bearing wax and the amount of wax borne by these bees did not differ between the experiments. This meant that the queenless and queenright colonies had the potential to construct equal amounts of comb as the amounts of wax available for comb building was the same. Contrary to this prediction, queenright colonies constructed 8 times more comb than their queenless counterparts. Queenright Apis mellifera scutellata colonies constructed 4 times more comb than their queenless counterparts. The increased amount of 9-oxo-2-decanoic acid (90DA) in the A.m.capensis mandibular gland secretions could not alone account for this difference. In fact, A.m.capensis and A.m.scutellata colonies constructed similar amounts of comb when they were given their own queens or queens from the other race. Worker bees need to have direct contact with their queen for comb building to be enhanced. Even when the queen had her mandibular glands extirpated and tergite glands occluded large amounts of comb were constructed than when access to the queen was limited. Direct access to the head of a mated queen proved to be the stimulus enhancing comb building. No comb was constructed when the workers had access to the abdomen of the queen. Virgin queens did not stimulate comb building. The relatively large amounts of 90DA and 9HDA from the mandibular glands of Cape virgin queens had not influenced comb building. Worker sized cells were generally constructed. These cells were slightly smaller than those constructed by European honeybees, but were indicative of African bees. A few queen less colonies constructed cells that were of an intermediate drone and worker size. Four mandibular gland pneromones were measured by gas chromatography. No correlations between these pheromones and the comb construction measurements were found. It is unlikely that the mandibular gland pheromones are the only pheromones that stimulate comb building. Pheromones from other glands on the head may contribute towards the enhancement of comb building, and they are not present in virgin queens

Towards a spirituality for authentic liberation in South Africa

  • Description: A spirituality which facilitates authentic liberation is one which intuits the evolutive nature of human development. Justice and compassion are biblical descriptions of a liberation effected by the Holy Spirit in and through persons. The development of persons towards being able to embrace such qualities is set within three interconnected paradigms: a theological paradigm, a psychological paradigm, and a socio-historical paradigm. The theological paradigm sees the creative process as continuing an evolutive movement towards the wholeness of persons, society and the cosmos. Within this, persons are defined as created co-creators with God, and are given the responsibility of participating in the process which will achieve this goal. This paradigm is reflected in the works of Pierre Teilhard de Chardin concerning the evolution of consciousness within each material form, towards union in God. The psychological paradigm suggests that the evolution of consciousness within persons gives rise to the probability of the emergence of levels of consciousness capable of initiating and sustaining the manifestation of justice and compassion. In this evolutive process a boundary is perceived by persons between the ego-body as 'self' and the environment as 'not-self'. This boundary prohibits the emergence of the qualities of justice and compassion in human consciousness. The developmental process is constituted by the integration of the 'not-self' into the 'self' at each stage, facilitating the emergence of a consciousness which takes responsibility for the environment as 'self'. The socio-historical paradigm is defined by the perspectives on the world held by the poor. The spirituality emerging from within this paradigm is initiated through encounter with Jesus. It is concretized in a preferential option for the empowerment of the poor, which facilitates and sustains the integration of 'self' and the environment. An examination of the Latin American base Christian communities shows the characteristics of Church life and structure which facilitate the Church becoming the locus of development towards authentic personal and social liberation. The structure of the Church of the Province of Southern Africa is evaluated in this light, in order to encourage clergy and laity to rise towards their full personhood in God.

  • Description: From Introduction: In the middle of the eighteenth century, when Haydn began composing his first string quartets, violin writing was highly advanced and the violin an established solo instrument, its supremacy already firmly endorsed by the Italian Violin Schools of the seventeenth and early eighteenth centuries. The pace of development of the cello, however, was not comparable to that of the violin, despite the fact that the first cello known to us was made in 1572.

  • Description: 1. The external morphology of all stages in the life cycle of B. decoloratus is described with the aid of scanning electron micrographs. 2. The biological activities of B. decoloratus during its parasitic cycle are examined with special reference to the course of feeding of all stages, and to the influence of the pharate nymph and adult conditions in accelerating the completion of the cycle. 3. The pattern of dropping of replete females is considered in relation to their weight and their time of drop-off. 4. The adult male population structure is described. Two distinct weight groups are reported and the taxonomic significance of these is discussed. 5. The preoviposition period duration of B .decoloratus was studied under laboratory conditions and found to be temperature dependent and humidity independent. Female size, as implied by their engorged weights, influenced the duration of the oviposition period: ticks weighing less than 20 mg possessed longer preoviposition periods. 6. The preoviposition period of B.decoloratus females under fluctuating macroclimatic conditions was studied and found to be long in duration. The implications of this are discussed in relation to laboratory findings and the summer build-up of this species in nature. 7. The duration of the oviposition period of B. decoloratus and the number of eggs produced during this period were studied under laboratory and field conditions. Both these parameters were found to be temperature dependent and uninfluenced by humidity. The significance of a temperature dependent oviposition period is discussed. 8. The minimum amount of 'blood' required by female ticks for oviposition of eggs was found to be approximately 16 mg. under laboratory conditions. 9. The oviposition behaviour of B. decoloratus females has been described and the water relations of ovipositing and non-ovipositing females were examined and discussed . 10. The effects of handling female ticks during their oviposition period was studied and females which were handled were found to produce significantly fewer eggs. The significance of this is discussed. 11. During preliminary experiments on the incubation period of B. decoloratus it was found that the viability of eggs laid during the first half of the oviposlting period was greater than for eggs laid in the second half of the period. The critical temperature of the 'wax' coating of eggs was found to be 42⁰C while the critical humidity was approximately 70% R.H. (7,53 mmHg) at 26⁰C. The implications of these findings are discussed. 12. The development of eggs, traced throughout the incubation period by monitoring the build-up of guanine spectrophotometrically, was studied under different humidity conditions . Successful development was found to be dependent on the water content of the eggs at the time of laying. As eggs were also found to be unable to take up water vapour from the atmosphere this finding is important evidence to support the suggestion that the survival of the egg stage largely determines the spacial distribution of larvae in the field. 13. Results of work done at constant, alternating and naturally fluctuating temperatures and humidities demonstrated that the duration of the incubation period of B.decoloratus is temperature dependent and humidity independent. The significance of this is discussed in relation to the findings of previous workers and to the biology of the species. 14. Egg viability (percentage hatch) was found to be humidity dependent and temperature independent. The implications of these findings are discussed. 15. Some of the problems associated with the assessment of the effects of climatic conditions on ticks are discussed. Special reference has been made to the advocation of using saturation deficit instead of relative humidity as the parameter indicative of environmental humidity in any biological study involving fluctuating humidity conditions. 16. The problems associated with having three variables (e.g. temperature, saturation deficit and incubation period duration) are discussed and reasons given for why contour diagrams have been used in this investigation. 17. A model of the interactions between the main abiotic factors of the environment (temperature and humidity) and the biological parameters studied during the second part of this investigation is presented. 18. The effects of climatic conditions on the life cycle and distribution of B.decoloratus are discussed. Special reference has been made to the available evidence explaining the summer build-up in tick numbers known to occur in nature and the way in which the present findings have helped in an understanding of the spacial distribution of B.decoloratus in the field.

  • Description: It would indeed have been a difficult matter for anybody possessing a taste for self-expression, a facility with words and an insatiable imagination to avoid becoming involved in political controversy in England during the early part of the Eighteenth Century. For one who, in addition, was confident in his ability to solve problems of state of whatever complexity it was clearly an impossibility. Daniel Defoe's close connection with politics during the first years of the Eighteenth Century involved him in numerous hardships. In later years it brought him much less fame than his excursions into fiction; but it was the means of providing him, albeit sparsely at times, with sufficient money to keep his creditors at bay. On more than one occasion the protection he gained helped to rescue him from imprisonment. Intro., p. 1.
