Rent-sharing, hold-up, and manufacturing wages in Cote d'Ivoire
No full textLabor costs in Francophone Africa are considered high by the standards of low-income countries, at least in the formal sector. Are they a brake on industrialization, or the result of successful enterprise development? Are they imposed on firms by powerful unions, or government regulations, or a by-product of good firm performance? The authors empirically analyze what determines manufacturing wages in Cote d'Ivoire, using an unbalanced panel of individual wages that allows them to control for observable firm-specific effects. They test the rent-sharing, and hold-up theories of wage determination, as well as some aspects of efficiency-wage theories. Their results lean in favor of both rent-sharing, and hold-up, suggesting that workers have some bargaining power, and that in Cote d'Ivoire workers can force renegotiation of labor contracts, in response to new investments.Economic Theory&Research,Public Health Promotion,Health Monitoring&Evaluation,Labor Policies,Environmental Economics&Policies,Economic Theory&Research,Environmental Economics&Policies,Health Monitoring&Evaluation,Health Economics&Finance,Statistical&Mathematical Sciences

Cracking of Some Polytropic Models Via Local Density Perturbations
No full textIn this paper, we have checked the stability of some anisotropic charged generalized polytropic models by using the concept of cracking, founded by Nasim and Azam [29]. The process of cracking is intuitive and results at the points where the dispensation of radial forces appears in the system on account of perturbation and carried the system out of its equilibrium state. We have employed the local density perturbation technique to hydrostatic equilibrium equation and on all the physical parameters engaged in the models. We concluded that under the local density perturbation scheme all the generalized polytropic models are potentially stable.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

A study on the maintenance management of food courts / Azam Mohamad.
No full textThere is a growing need and demand in food and beverage service in Malaysia. This can be seen from the emerging of eating venues that come in the form of restaurant, food court and stalls. The study focuses on the Klang Valley area only in order to limit the scope of the study. To support this research, four numbers of food courts were selected as case studies. The primary and secondary data were gathered from questionnaire surveys, observation and interviews conducted as well as references to the published reports, seminars papers and published books. It can be summarized that the maintenance management of food courts are not being progressively undertaken and performed due to non-existence of a quality standard guideline for the maintenance works, programme and the failure to set up an appropriate maintenance management to oversee the implementation of the maintenance works. Lack of supervision and inspection is another contributing factors on the failure of carrying out appropriate and standardized maintenance works. Maintenance management of a food court in Malaysia is carried out in a general manner rather than intuitive and progressive schedule. In addition, the opinions of maintenance management implementation and quality standard were gathered through structured interview and the results were then critically analyzed. From the findings, the author hopes that the research would give clear perception to the reader on the current practice of maintenance management and its implementation in the local market. It is recommended that a research on the same topic to be undertaken on other municipalities. In addition to this, detailed studies on the frequency of maintenance works, procedures on the maintenance works carried- out and quality assurance or inspection (QA/QC) to be also included

Behaviour of Shear-Critical Reinforced Concrete Beams Strengthened with Fiber Reinforced Cementitious Mortar
No full textExtensive research has been conducted on strengthening of shear-critical reinforced concrete (RC) beams, particularly using fiber reinforced polymer (FRP) strengthening systems. This previous research has helped to better understand the behaviour of shear strengthening systems and has improved the performance of existing shear strengthening systems. However, there is still a potential to further improve upon the performance of existing shear strengthening systems. A cement-based composite system is an innovative strengthening system that has similar benefits (such as light weight, ease of installation and non-corroding) to FRP systems, but overcomes some of the draw backs (such as poor compatibility with concrete substrate, lack of vapour permeability and fire resistance) of using epoxy as bonding agent in FRP systems. A cement-based composite replaces the epoxy with cementitious mortar and the fiber sheets with fabric or grids.
The current study presents the results of an experimental study conducted to investigate the effectiveness of cement-based composite systems in comparison to an existing epoxy-based system (carbon fiber reinforced polymer, CFRP) to strengthen shear-critical RC beams. Two types of cement-based systems were investigated in this study: carbon fiber reinforced polymer (CFRP) grid embedded in mortar (CGM) and carbon fabric reinforced cementitious mortar (CFRCM).
The experimental study consisted of two phases. Phase I focused on flexural testing of seven medium-scale shear-critical reinforced concrete (RC) beams. The objective of this phase was to evaluate the potential of FRCM shear strengthening. The test variables included the type of FRCM (carbon FRCM or CFRCM and glass FRCM or GFRCM) and the strengthening scheme (side bonded vs. U-wrapped). Phase II was designed based on results of Phase I study, and it consisted of flexural testing of twenty (20) large-scale shear-critical RC beams strengthened with cement-based systems. The objective of this phase was to evaluate the effectiveness of the two types of cement-based strengthening systems in comparison to the existing epoxy-based FRP system. The test variables included: the shear span to depth ratio (slender and deep beams), amount of internal transverse steel reinforcement and type of strengthening system (CFRCM, CGM and CFRP).
The results showed that the cement-based systems (CFRP grid in mortar and CFRCM) performed better compared to the epoxy-based system (CFRP sheet) in terms of the increase in shear capacity relative to the ultimate strength of the strengthening systems. The results also showed that the bond of cement–based system with the concrete substrate was sufficient that u-wrapping may not be required; the studied side-bonded systems did not exhibit signs of premature debonding. This is in contrast to most FRP fabric strengthening systems were u-wrapping is required for adequate bond. In addition, cement-based systems exhibited a better ability to control diagonal (shear) crack widths compared to the epoxy-based system tested, providing a greater reduction in diagonal crack width despite the relative lower ultimate strength and stiffness of the cement-based systems. Shear strengthening resulted in reduced shear strength contribution from stirrups. The strengthened beams with stirrups exhibited steeper shear cracks compared to control unstrengthened beams with stirrups. Similarly, the presence of stirrups reduces the shear strength contribution from strengthening. Again, the addition of stirrups results in steeper shear cracks which intersect fewer fibers tows in the strengthening system which results in a reduced shear strength contribution from strengthening layer. Lastly, the existing models to predict the ultimate load of strengthened shear-critical RC beams were evaluated and modifications to these methods were proposed
Behaviour of Shear Critical RC Beams with Corroded Longitudinal Steel Reinforcement
No full textThis thesis discusses the results of an experimental program designed to investigate the effect of corrosion on the behaviour of shear critical reinforced concrete (RC) beams. The results of twenty RC beams (ten deep beams and ten slender beams) are described and discussed. The test variables included: corrosion level (2.5%, 5% and 7.5%) and existence of stirrups (beams without stirrups and beams with stirrups). The feasibility of repairing the corroded shear critical RC beams with CFRP laminates was also investigated.
Sixteen specimens were corroded using an accelerated corrosion technique whereas four specimens acted as control un-corroded. Following the corrosion phase, all specimens were tested to failure under three point bending. Test results revealed that the corrosion does not adversely affect the behaviour of shear critical RC beams rather it improves their behaviour. It was found that corrosion changed the failure mode of the corroded beams. The control un-corroded deep beams (beams with and without stirrups) failed in shear-compression failure whereas corroded deep beams (beams with and without stirrups) failed by splitting of the compression strut. The control un-corroded slender beams (beams with and without stirrups) failed in diagonal tension failure whereas the corroded slender beams failed in anchorage failure (beams without stirrups) and flexural failure (beams with stirrups).
The analysis of the results showed that corrosion changed the load transfer mechanism and the change of failure mode was associated with the mechanism. The load transfer mechanism changed from a combination of beam and arch action in the control un-corroded deep beams to pure arch action in the corroded deep beams. The load transfer mechanism changed from pure beam action in the control un-corroded slender beams to pure arch action in the corroded slender beams.
Two strut and tie models are proposed: one for corroded deep beams and one for corroded slender beams. The ultimate loads of the corroded beams were predicted using these struts and tie models and compared with the experimental results. A very good correlation was found between predicted and experimental results
