Studies on N,N'-bis(8-acetyl-7-hydroxy-4- methylcoumarin)ethylenediamine complexes of trivalent lanthanides

922-923Complexes having the composition LnL(H2O)Cl.(where Ln = trivalent lanthanides and H2L= schiff base derived from the condensation of 8-acetyl-7-hydroxy-4-methylcoumarin with ethylenediamine) have been prepared and characterized by elemental analysis, conductance, magnetic moment, TG and DT, electronic and infrared spectral measurements. The conductivity measurements show non-electrolytic nature of the complexes. The schiff base behaves as a dibasic tetradentate ligand with O:N:N:O donor sequence

Relativistic segnificance of curvature tensors

In thi paper new curvature tensors have been defined on the lines of Weyl's projective curvature tensor and it has been shown that the distribution (order in which the vectors in question are arranged before being acted upon by the tensor in question) of vector field over the metric potentials and matter tensors plays an important role in shaping the various physical and geometrical properties of a tensor viz the formulation of gravitational waves, reduction of electromagnetic field to a purely electric field, vanishing of the contracted tensor in an Einstein Space and the cyclic property

Joint Moderating Effect of Perceived Equity and Supervisor Support on the Relationship between Employee Compensation and Employee Performance in Kenyan Chartered Public Universities

Compensation is essential to the functioning of the relationship between the employee and employer and close to the heart of both the employer and the employee.  Perceived unfairness in compensation can be harmful to an organization. When employees believe that they are not paid equitably they will be dissatisfied with work which can lead to voluntary employee turn-over, regular absence from work, non-commitment to the organization and low-trust employee relations. Lack of clear criteria and unfairness in distributing incentives to academic staff and supportive supervisors could influence academic staff motivation and performance. There is need to consider fairness in distributing incentives and to have supportive supervisors who will motivate the academic staff and in turn improve their performance. The main objective of this study was to establish the joint effect of perceived equity and supervisor support on the relationship between employee compensation and employee performance in Kenyan chartered public universities. The study was based on three theories: Expectancy Theory, Equity Theory and Social Exchange Theory.  The study adopted positivist research philosophy. Descriptive cross-sectional design was adopted to enable the researcher discover the relationship between different variables. The study targeted academic staff in 23 Kenyan chartered public universities.  Multistage sampling technique was used to identify respondents from Kenyan Chartered Public Universities. The number of Faculties/Schools/Institutes sampled was 43 out of 246. A sample size of 370 academic staff was selected from a population of 2011 using easy sample size calculator. Data was collected on employee compensation, employee motivation, perceived equity, supervisor support and employee performance using a questionnaire. A pilot study was carried out at one university to validate the data collection instrument. Reliability results indicated a Cronbach Alpha value of 0.920. Out of 370 questionnaires administered, 247 were returned and analyzed, thus a response rate of 69 percent. Test of normality, linearity, multicollinearity and homoscedasticity revealed that the data was normally distributed, linear and independent of errors. Quantitative technique was used to analyze data. The study established that employee compensation and employee performance in Kenyan chartered public universities is jointly moderated by perceived equity and supervisor support (R2=0.37, p<0.05). The study concluded that the relationship between employee compensation and employee performance is jointly moderated by perceived equity and supervisor support. The study recommended in enhancing employee performance through employee compensation, perceived equity and supervisor support are crucial since they moderate the underlying relationship. Keywords: Employee compensation, perceived equity, supervisor support, employee performance, academic staff, Kenyan chartered public universities

THE INFLUENCE OF FIRM-LEVEL FACTORS ON THE RELATIONSHIP BETWEEN STRATEGIC PLANNING AND PERFORMANCE OF ORGANIZATIONS

This study was based on conceptualized relationship between strategic planning (SP),firm-level factors and performance. Some researchers have argued that strategicplanning influences performance positively while others contend that the influence isnegative. Therefore, the past empirical studies have produced many contradictoryfindings and there is a need for further studies to fix this empirical conundrum. Otherresearchers have posited that the central tenet in strategic management is that a matchbetween firm resources and capabilities are critical to performance, and that astrategist’s job is to find or create this match. Hence, there was need for more researchon the moderating influence of firm-level factors on the relationship between strategicplanning and performance. These variables were contextualized in the manufacturingfirms in Kenya. The current study had one objective, to establish the influence of firmlevelfactors on the relationship between strategic planning and performance ofmanufacturing firms in Kenya. A corresponding hypothesis, firm-level factors have amoderated influence on the relationship between strategic planning and performance ofmanufacturing firms in Kenya, was formulated and tested at 95 percent confidence level.Through a cross-sectional descriptive survey, data was obtained using a structuredquestionnaire from 72 manufacturing firms representing 52.17 percent response rate.Data obtained were analyzed using both descriptive and inferential statistics.Hypothesis was tested using both simple and multiple regression analysis. StatisticalPackage for Social Sciences (SPSS) was used to analyze the data. The findingsestablished that firm-level factors had a significant moderating influence on therelationship between strategic planning and performance. The independent influencesof the firm-level factors’ indicators used were all significant. The study suggested thatthe managers of the manufacturing firms in Kenya need to synchronize the strategicplanning and firm-level factors for superior performance. Current study’s findingshave theory, policy, managerial practice and methodological implications. The findingssupport resource based view theory. On policy and managerial practice, manufacturingfirms’ management should be motivated to attract valuable resources anto attract valuable resources and capabilitieswhich are valuable, rare, not easily imitated, and cannot be substituted as they create sustainable competitive advantage hence propel organizations to better performance.The use of regression method in analysis made it very easy to test the hypothesis which  was developed to attain research objective

STRATEGIC PLANNING AND PERFORMANCE OF ORGANIZATIONS

This study was based on conceptualized relationship between strategic planning andperformance. Some researchers have argued that strategic planning influencesperformance positively while others contend that the influence is negative. Therefore,the past empirical studies have produced many contradictory findings and there is aneed for further studies to fix this empirical conundrum. These variables werecontextualized in the manufacturing firms in Kenya. Current study’s objective was todetermine the relationship between strategic planning and performance ofmanufacturing firms in Kenya. A corresponding hypothesis, there is a relationshipbetween strategic planning and performance of manufacturing firms in Kenya, wasformulated and tested at 95 percent confidence level. Through a cross-sectionaldescriptive survey, data were obtained using a structured questionnaire from 72manufacturing firms representing 52.17 percent response rate. Data obtained wereanalyzed using both descriptive and inferential statistics. Hypothesis was tested usingboth simple and multiple regression analysis. Statistical Package for Social Sciences(SPSS) was used to analyze the data. The findings established that strategic planninghad a strong positive relationship with performance of manufacturing firms in Kenyaand the influence was statistically significant. However there were mixed results asregards the independent influence of various strategic planning indicators onperformance. But when combined, they have strong positive relationship withperformance and influence was statistically significant. The study suggested thatmanufacturing firms in Kenya should practice strategic planning for superiorperformance. For further study, it was suggested that the relationship to be moderatedwith organizational variables, external environment dynamics and also to try differentstrategic planning steps. Current study’s findings have theory, policy, managerialpractice and methodological implications. The current study findings added to theexisting body of literature by empirically corroborating that strategic planning andperformance had a positive relationship. Manufacturing firms should have policieswhich enforce various accreditations which for
