Effects of Reward Systems on Performance of Construction Workers in Ghana

One major problem facing organizational managers all over the world and in all sectors of every economy, be they private or public, is how to obtain optimum performance from employees. This is possible when an employee on individual and/or group level is highly recognized and rewarded for performance. It is therefore relevant to explore the effects of reward systems on the performance of construction workers in Ghana. This is what has been done and reported in this paper. Contractors with D1K1 classification, working or undertaking projects in the Northern part of Ghana and had elaborate and distinct system of rewarding employees were involved in the survey. A combination of interview and questionnaire administration was used to gather data. Respondents were chosen, based on their level of exposure to site administration of construction projects, and involvement] of the construction project. Through hypothesis testing, the Pearson chi-square results indicate a significant positive association between reward systems and performance with asymptotic significance level of less than 0.05. The findings indicate non-financial rewards were as important as financial rewards to improve the performance of employees. This paper recommends a multiple function and integration of framework which seeks to attract, retain and motivate employees to induce higher performance. Keywords: financial rewards, non-financial rewards, performance, construction industry

Kankakee River Basin in Illinois: hydraulics, hydrology, river geometry, and sand bars interim report

This interim report summarizes the work completed within the first nine months of the project. This report summarizes all of the existing streamflow records for Illinois and for two stations from Indiana, lists the available literature, and describes the field trip to the site. Analyses of the bed and bank material samples collected during the field trip also are included. Maps of the bank lines from the Route 30 Bridge in Indiana to the confluence of the Kankakee River with the Des Plaines River have been completed and will be available with the final report. Bank conditions of the entire main stem of the Kankakee River from the Route 30 Bridge in Indiana to its confluence with the Des Plaines River are also summarized. This includes general bank conditions, shoreline stability, erosion sites and severity, pumping stations, log and tree jams, and other features. Additional work on the surveying of the river and sand bar geometries is now being done. A final report will be prepared that summarizes all of the existing and newly collected data on hydraulics, hydrology, sediment transport, bed and bank material distributions, and sedimentation patterns

Hydraulics of Flow in the Kaskaskia River, Illinois

The hydraulics of flow was investigated at two reaches in the Kaskaskia River. The discharge varied from 58 to 4000 cfs and the flow frequency varied from 5 to 88 percent. The head loss varied from 0.96 ft/ mile for high flows to 1.98 ft/mile for low flows. The vertical velocity distribution was found to follow a logarithmic distribution. A theoretical distribution predicted the lateral velocity distribution in the bends reasonably well. In all, 79 isovels were developed for all flow conditions. The average value of the energy coefficient was 1.45 for straight reaches and 1.43 for bends. Similarly, the average value of the momentum coefficient was 1.22 for straight reaches and 1.18 for bends. Manning’s roughness coefficient varied from 0.039 to 0.053. During low flows. the river flows through a series of pools and riffles. The median diameter of bed materials varied from 40 mm in the riffle to 0.04 mm in the pool, whereas the Froude number changed from 0.7 to 0.01. During high flows, the effect of the pool and riffle on the flow condition is minimal or nonexistent.publishedpeer reviewedOpe
