- Description: This study explored the phenomenon of juvenile delinquency in grandparent headed families in Hill Crest, Alice township, Eastern Cape. The study endeavoured to achieve the following specific objectives: (I) to determine the factors associated with juvenile delinquency in grandparent headed family environments; (ii) to ascertain the experiences encountered by grandparent headed families due to juvenile delinquency. (iii) to establish the support system provided by the relevant stakeholders (probation officers, police, school officials and grandparents) to address juvenile delinquency in grandparent headed families. The study was premised on theoretical lenses of the social bond theory, social learning theory and general strain theory. Methodologically, the study used the qualitative approach guided by the exploratory-descriptive research design and phenomenology was adopted as the specific research design. The data was collected through in-depth one-on-one interviews, focus group discussions and key informant method. Also, the study used non-probability method sample selection, specifically purposive sampling technique was used. Using this technique, nineteen (19) participants were selected comprised of five (5) grandchildren, eighty (8) grandparents, two (2) probation officers, two (2) police officers, one (1) community committee member and one (1) school official. Data were analysed through thematic analysis. The study revealed the following findings: the grandparent household have unique factors that are contributing to juvenile delinquency these include old age, overprotection, backgrounds of grandchildren to mention but just a few; delinquency by grandchildren has spill over effects that are adversely affecting the lives of grandparents for instance health deterioration, victimisation and loss of property; ii grandparents have their own means of addressing juvenile delinquency such as corporal punishment, emotional attachment and religion; the department of social development has programmes in place to assist grandparents, however, they are facing some challenges in effectively execute them; relevant stakeholders such as police and schools shown reluctance in addressing juvenile delinquency in grandparent headed families. Based on the evidence gathered, this study made the following recommendations: development of programmes to assist grandparent headed households on parenting; mentoring programmes for vulnerable children; the appointment and active involvement of youth workers; social development need to need to regard probation as a specialised area and policies should be developed protecting old aged persons from taking full custody of children. The study concluded that grandparent headed households are contributing to juvenile delinquency and old age was determined to be the central key factor giving birth to this quagmire.

- Description: Inadequate quantity is a major impediment to the industrial application of peroxidase and other industrial enzymes. Consequently, efforts are geared towards increasing peroxidase production by searching for new microbes with enhanced production capacity. In this study, three novel ligninolytic bacteria: Raoultella ornithinolytica OKOH-1 (KX640917), Ensifer adhaerens NWODO-2 (KX640918) and Bacillus sp. FALADE-1 (KX640922) were optimized for peroxidase production and their peroxidases characterized using molecular and biochemical approaches. Molecular analysis confirmed the presence of peroxidase genes in the three bacteria. BLAST result and phylogenetic analysis of the deduced amino acid sequences suggested that Raoultella ornithinolytica OKOH-1 peroxidase (RaoPrx) belongs to a DyP-type peroxidase family while peroxidases from Ensifer adhaerens NWODO-2 and Bacillus sp. FALADE-1 are catalase-peroxidases. The peroxidase genes are available in the GenBank with MF370527, MF374336 and MF407314 as respective accession numbers. Upon optimization, Raoultella ornithinolytica OKOH-1 exhibited the highest peroxidase production at pH 5, 35 oC and 150 rpm. Biochemical characterization showed that RaoPrx had a wide substrate specificity as it was able to oxidize all the tested substrates in this study (ABTS, veratryl alcohol, guaiacol and pyrogallol), except 2, 6-Dimethoxyphenol. However, highest activity by the enzyme was recorded with pyrogallol as substrate. The enzyme had an optimum activity at pH 6 and 50 oC and was very stable at high temperatures (50 oC – 70 oC). Its pH stability was over a pH range of 5.0 – 7.0. Moreover, RaoPrx activity was significantly enhanced by Ag+, Cu2+, Zn2+and Fe2+ while Ca2+, Mg2+, Ba2+, Al3+, Co2+, NaN3 and EDTA inhibited the activity of the enzyme. Nevertheless, RaoPrx exhibited a remarkable dye-decolourizing activity on congo red and melanin, indicating the biotechnological potential of the enzyme in dye decolourization and development of cosmetic agent. Generally, the results from this study suggest that ligninolytic bacteria hold a great potential for enhanced peroxidase production that could meet the increasing industrial demand.

- Description: African countries have become synonymous with policy drafters and abortive policy implementers. After independence from long period colonialism, slavery and apartheid, African states policy administrators began putting in place policies to improve either the living conditions of citizens or the inequities emanating from the administration of colonial governments. However, these policies do little to naught to meet the aforementioned goals. The Free Education Systems in Nigeria and Ghana, and the Indigenization Policy in Zimbabwe are examples of policies that experienced miscarriage of policy implementation in the past. This study therefore, aspires to explore the Broad Based Black Economic Empowerment policy implementation in the forest sector and specifically identify bottlenecks in the implementation processes in South Africa. Qualitative approach was used in order to meet the primary and secondary objectives of the study. Semi structured interview questions were administered to relevant companies, institutions and the municipality which were purposely sampled to capture the processes of the BBBEE implementation. The study revealed that measured entities are complying with the prescript of the policy but that finance and a continuous policy amendment presents a bottleneck in the implementation dynamics. Lastly, labour intensive measured entities find it impossible to meet the skills development element due to high cost of training. These results suggest that the value envisaged is not being met. The study also found that verification agencies are effectively providing their watchdog function in the implementation of the policy however the use of technology is non-existent in monitoring the process. Finally the study found that agencies are hired by measured entities to verify their BBBEE status which presents a huge inducement for both parties to collude. It also found that the policy is implemented in a top-down approach hence municipalities have been relegated from the implementation process. The study recommends decentralization of the policy in a strategy called Local Economic Equity for the Disadvantaged (LEED) which involves the expertise of white South Africans and permanent resident people in order to build truly inclusive society envisaged by the Constitution of South Africa. Additionally, it recommends the use of technology dubbed e-BBBEE to implement the policy.
