Congestion problems can be approached from the viewpoint of system dynamics theory. The relationship between road capacity and congestion can be explained by the 'relative control' archetype among four system archetypes suggested by Wolstenholme. There is a balancing feedback loop between road capacity and road congestion. However, there is another balancing loop between road congestion and car traffic volume, which keeps disrupting the equilibrium of the former loop. A system dynamics model, which is based on a partial adjustment model of induced traffic in the literature, is built to simulate three road building scenarios: 'Expanding investment', 'Balancing investment' and 'Frozen road investment' scenarios. The 'Expanding investment' scenario manages to drop congestion levels by 9% over 30 years, however, causing much higher emissions of $CO_2$ than other scenarios. The trade-off relationship between congestion levels and environmental costs must be taken into consideration for road investment policies.

This study investigates what effects employment flexibility have on the business performance in the computer programming, system consultancy and related services. An analysis of the effects of employment flexibility on outcomes of human resource management revealed that companies which had a higher proportion of temporary agency workers and adjusted employment more frequently had higher turnover rates. The study also showed that the higher the proportion of non-regular workers, outsourcing and the easier it was to adjust working hours, the higher the absence rate. Meanwhile, companies that made employment adjustments more often showed higher defect rates and lower customer satisfaction. It was also found that in companies with a higher proportion of outsourcing and higher possibility of employment adjustments, workers were less interested in new technologies.

Nigeria like many other developing countries' eagerness to accelerate socio-economic development has prompted her to adopt several approaches over the years since independence. These have ranged from the import substitution scheme, the indigenisation policy, and structural adjustment programme to the national economic empowerment development strategy. Nigeria has sought to widen her economic base by engaging in increased cross-border trade and investment activities. This is with a view to spurring the process of industrialization and ultimately lowering the level of poverty in the country. This has led to the formulation of various industrial policies and processes, all geared towards integration into the world economy. Using secondary sources, this paper seeks to analyze Nigeria's journey towards industrial development especially within the context of globalization. It concludes by explaining the impact of the new economic paradigm on the country's quest to industrialize and recommends alternative path towards development and growth.

Compared to the specialist program, the advanced general dentistry program (AGD) is designed to guarantee that dentists dealing with primary care services possess overall dental care proficiency and contribute to offering better care to customers. This program is also believed to help resolve the imbalance among the number of candidates for specialization, which came to the authorities' attention throughout the implementation of the dental specialist program. KDA will continue to implement AGD while pushing for the establishment of the program by complementing it with adjustment measures and regulations provided the dental community agrees to such actions.

Product quality of perishable food is significantly affected by the environment. Technological approaches for tracking and tracing such products have attracted increasing attentions in both research and practice. This paper studies how supermarket can maximize profits of selling perishable food through price adjustment based on real-ime product quality and values. This can be achieved by tracing the value of the perishable food based on an automatic product identification technology Radio Frequency Identification(RFID). With the support of the RFID, an optimization model can be developed to enable product tracking and tracing. The analysis of the model shows promising benefits of applying a dynamic pricing policy and obtains the optimal ordering decision in the respect of deterministic demand function.

Recently, elevator inspection and self-examination were strengthened through the revision of the Elevator Safety Management Act, but there have been no significant reduction in serious accidents and major failures. Therefore, the government intends to lay the foundation for reflecting the safety quality rating system, which adjusts the elevator inspection cycle, as a policy to induce safety management of preemptive and active management entities. This study systematically reviewed and classified the safety quality rating system for elevator inspection cycle adjustment in previous studies, collected expert opinions, and reconstructed the key items into realistic evaluation items, and evaluated and scored the relative importance of each factor through the AHP technique.
