ABSTRACT:In a two-year study, aqueous seed extracts of the neem tree Azadirachta indica A. Juss (Meliaceae) and Bacillus thurigiensis (Bt) were evaluated in the field for the management of pests of okra, Abelmoschus esculentus (L.) Moench. The aqueous neem seed extracts were applied at the rate of 30, 50, 75 and 100 g/l and B.thurigiensis was applied at the rate 1.0 g/l of water. Actellic 25 EC, a synthetic insecticide, was applied at the rate of 2 ml/l as standard check. Arthropod fauna on okra were sampled using traps, sweep nets, aspirators and handpicking. The nature of damage caused to the stems, leaves, flowers and fruit was assessed by visual observation. The major insect pests of okra collected were Podagrica uniformis Jac, Aphis gossypii Glov, Sylepta derogata (F.), Spodoptera litoralis Boisd, Prodenia litura (F.), Dysdercus superstitiosus (F.), Epilachna similis (F.), Bemisia tabaci (Genn.) and Zonocerus variegatus (F.). These pests were observed attacking mainly the leaves of okra. Some of the minor pests identified were Lagria villosa (F.), L. cuprina Thoms, Mylabris temporalis Wellni, M. trifasciata (Thumb.), Lapidognatha sp and Empoasca devastans (D.). Actellic, neem seed extract and Bt significantly reduced the population and damage caused by the major insect pests of okra recorded at Legon, Ghana compared to the untreated. Actellic and aqueous neem seed extracts were equally effective against the pests of okra and caused a significant reduction in insect damage to the leaves, flowers and fruit of the crop. There were no significant differences among the different dosages of neem seed extract on all the parameters assessed, with the exception of the final fruit yield. Actellic, neem extracts or Bt produced higher yield of marketable fruit of okra than untreated plants. Neem seed extract applied at the rate of 30 g/l of water to okra plants produced lower fruit yield than those treated with 50 g or more. Aqueous neem seed extracts and Bt can be used effectively by farmers as a component of integrated management of pests of okra in Ghana.

a b s t r a c tManagerial women experience a number of work-related stressors which produce strain symptoms that function as predictors of their ill-health in organizations. This finding is made from a study that examined the existing relationships among job characteristics symptoms of stress, and the development of health outcomes (depression, anxiety and physical symptoms) among women in lower and middle management positions in some organizations in Ghana. The stratified and simple random sampling procedure was used to select the study participants which numbered 170 female managers. Data was collected using both questionnaires and interviews, and analyzed using the Occupational Stress Indicator, the Depression, Anxiety and Stress Scale, and the Beck's Anxiety Inventory. It is concluded that since work-related stressors are predictors of women managers' ill-health in the work environment, organizations should be aware of the stressors in order to be able to guard against the deterioration of job performances of their women managers. Relevance to Industry: This study highlights the high prices organizations pay for the work-related stresses their women managers experience at the workplace, which impact negatively on their mental health, and by implication their productivity. Recommendations made can be used to enhance the managerial capacity and productivity of female managers at the workplace.

Social Capital is a concept that describes good quality social relations that can lead to mutual benefit. The fundamental proposition of social capital theory is that networks of relationships grant access to resources, especially information benefits not available to non-members of the network. This study assessed the functions of social capital within Ghanaian organizations, described the patterns and determinants of social capital use within organizations and explored how social capital contributes to firm performance using a sample frame of firms listed in the Ghana Club 100. A questionnaire field survey supplemented by personal interviews was chosen as the most appropriate design for this investigation. Employees were sampled across the organizational hierarchy based on their responsibilities held, positions, type of relationship held with others within the organisation. Data was also collected on the demographic characteristics and organisational dynamics. The results showed that social capital is critical to knowledge sharing in the Ghanaian organization; that it helps to get things done and helps in the attainment of organisational objectives. The findings also suggested that three determinate variables of social capital: reciprocity, trust and institutional ties, have the most significant positive relationship with organisational performance. In view of that, the study recommends that firms take a proactive approach towards promoting, building and maintaining viable social networks within their structures in order to derive maximum benefit from it.

The aim of this paper is to address entrepreneurship and ethics from the perspective of the Ghanaian entrepreneur in small and medium-size enterprises to extend our understanding of issues influencing entrepreneurial behavior in developing economies such as Ghana. Our study specifically addresses three typical situations in which business ethics are challenged: (1) When applying for business information and permits, (2) When competing for business contracts and financing and (3) When dealing with tax authorities. Relying on in-depth case-study data from 22 entrepreneurs, the paper conceptualizes entrepreneurial behavior related to business ethics and identifies several important challenges to overcome to enable economies to build a more effective market economy.

This study investigated the question of how culture and activity can be explored towards understanding the professional career development of married women and the relative constraints associated with such development in the Ghanaian environment. Guided by the cultural-historical activity theory (CHAT) framework, data was collected from a sample of 141 married Ghanaian women professionals engaged in white collar jobs in the public and private institutions located in Accra. It is established that the acceptance by the Ghanaian traditional society of the married professional woman as a capable person who can equally perform in an organization and thus need to be trusted, supported and recognized is of relevance to her career development. This observation provides learning on the impact of the inflow of socio-cultural dynamics into a gender-oriented organizational life and the complexities that it generates in understanding the constraints to the professional career development of married women.
