Action research : the use of enterprise resource planning system in construction engineering and project management

Although information communication technology (ICT) is long regard as very useful tool in today’s construction engineering and project management environment, organizations must not only operate based upon its original setting, but also requires on-going observation, additional features and fine is a very common phenomenon that organizations purchase the licensed “off their own business need. Due to the incapability of such software and inefficient customization, the possible result is making that ICT tool not user-friendly and sometimes the whole system becomes obsolete.

The purpose of this paper is to review and report those action organization to enhance the performance of its Enterprise Resource Planning (ERP) system launched in December 2002. Such actions include: improving data inputting method; removing the tran the organization’s “Delegation and Limits of Authority”; publishing the “League Table” amongst users; integrating the 3D Mode into the system and upgrading hardware.

Whilst the ultimate goals of such system are well beyond the time limit of this research study, an obvious interim result, achieved by this case studied organization, was winning a landmark project worth US$500 million after the ERP system was functioned prope and effectively. Their experience and success becomes an exemplar which can be borrowed by those companies, from managerial perspectives and as a roadmap, planning to adopt information technology (IT) strategy and use ICT tool in the construction engineering and project management framework. Singapore, where public housing provisions have been a major concern of their citizens as the building stock gets older.

Using multi-criteria decision analysis in natural resource management

The proposed volume aims to provide useful insights on the use of Multi-criteria Decision Analysis (MCDA) in natural resource management by examining a number of empirical applications for several countries and natural resources. There is increasing interest among researchers and policy makers in using MCDA to evaluate complex management issues and problems. While several books with empirical applications have been published, these applications are very recent. Evidence from major studies suggests that MCDA approaches to the management of water, forestry, wetland and other natural resources have substantially improved the design and implementation of natural resource and environmental policies. Using innovative approaches, such as MCDA, to manage complex natural systems will enhance our understanding and management of those systems. Stakeholder involvement is an important determinant of successful resource management, and MCDA provides a useful and effective framework for getting stakeholders involved in resource management decisions. Despite the general acceptance of the role of MCDA in natural resource management, problems remain in applying these techniques. Problems include difficulties in applying the techniques, eliciting required information, lack of suitable measures for environmental variables, and development of innovative methods to simplify the use of MCDA. The proposed book examines several applications of MCDA for several countries (Australia, USA and Europe) and natural resources, including forestry, water resources and vegetation.

Game theory applications in natural resource management : review of evidence, problems and potential

Game theory is a rapidly advancing approach to structure and understand complex management problems in the natural resources sector in both the developed and developing countries. Many natural resource problems are complex due to common property and public goods characteristics. Despite these limitations many researchers have used game theory to analyze water shed management, irrigation water management, grazing land management, and managing other ecological resources. The prisoner’s dilemma game has been widely used. The work of Runge shows that collective action is feasible if a critical mass of people can cooperate. The use of game theory is hindered by lack of information, paucity of empirical applications and the lack of interest by policy makers who wish quick answers to critical policy issues. The potential still remains high for game theory to be productively used both in developing and developed countries.

Building social capital in groups : facilitating skill development for natural resource management

Analysis of the experiences of four farmer groups set up to learn how to jointly manage local natural resource issues shows that the groups are going though two simultaneous processes. One builds technical competency in natural resource management and the other is the underpinning social process that allows the groups to make decisions and work collectively, which builds social capital. Natural resource management practitioners and farmers are practical people. They are likely to be more comfortable with a process that develops monitoring tools and benchmarks for natural resource management than a process of group development and social capital formation. Yet the two are intrinsically linked. This paper reflects on and analyses the experience of establishing and working with farmer groups as they go through a process of identifying environmental issues, setting and monitoring environmental benchmarks and identifying and implementing sustainable farming practices to meet the benchmarks.

Two questions emerged from the analysis. First, how do the four groups compare to other measures of effective natural resource management groups? Second, what are the characteristics of the groups that make them more or less effective and what has occurred in the groups (either before or during this project) to make them more or less effective? Social capital emerges as a key determinant of group effectiveness. Social capital is most effective when it comprises a balance of bonding and bridging networks, and includes shared values in relation to the purpose of the group.

Policy makers and extension workers need to understand the link between the two simultaneous processes occurring as people come together in groups to define and implement best practice at a local level, and how to use knowledge of social processes when designing the more concrete process of developing and implementing best practice monitoring and benchmarking with groups. An understanding of how people build social capital as they work in groups will assist with designing and facilitating group projects in a range of contexts, not only natural resource management.

Linking water-resource models to ecosystem-response models to guide water-resource planning -- an example from the Murray--Darling Basin, Australia

Objectively assessing ecological benefits of competing watering strategies is difficult. We present a framework of coupled models to compare scenarios, using the Coorong, the estuary for the MurrayDarling River system in South Australia, as a case study. The framework links outputs from recent modelling of the effects of climate change on water availability across the MurrayDarling Basin to a hydrodynamic model for the Coorong, and then an ecosystem-response model. The approach has significant advantages, including the following: (1) evaluating management actions is straightforward because of relatively tight coupling between impacts on hydrology and ecology; (2) scenarios of 111 years reveal the impacts of realistic climatic and flow variability on Coorong ecology; and (3) ecological impact is represented in the model by a series of ecosystem states, integrating across many organisms, not just iconic species. We applied the approach to four flow scenarios, comparing conditions without development, current water-use levels, and two predicted future climate scenarios. Simulation produced a range of hydrodynamic conditions and consequent distributions of ecosystem states, allowing managers to compare scenarios. This approach could be used with many climates and/or management actions for optimisation of flow delivery to environmental assets.

Flood forecasting in large rivers with data-driven models

Results from the application of adaptive neuro-fuzzy inference system (ANFIS) to forecast water levels at 3 stations along the mainstream of the Lower Mekong River are reported in this paper. The study investigated the effects of including water levels from upstream stations and tributaries, and rainfall as inputs to ANFIS models developed for the 3 stations. When upstream water levels in the mainstream were used as input, improvements to forecasts were realized only when the water levels from 1 or at most 2 upstream stations were included. This is because when there are significant contributions of flow from the tributaries, the correlation between the water levels in the upstream stations and stations of interest decreases, limiting the effectiveness of including water levels from upstream stations as inputs. In addition, only improvements at short lead times were achieved. Including the water level from the tributaries did not significantly improve forecast results. This is attributed mainly to the fact that the flow contributions represented by the tributaries may not be significant enough, given that there could be large volume of flow discharging directly from the catchments which are ungauged, into the mainstream. The largest improvement for 1-day forecasts was obtained for Kratie station where lateral flow contribution was 17 %, the highest for the 3 stations considered. The inclusion of rainfall as input resulted in significant improvements to long-term forecasts. For Thakhek, where rainfall is most significant, the persistence index and coefficient of efficiency for 5-lead-day forecasts improved from 0.17 to 0.44 and 0.89 to 0.93, respectively, whereas the root mean square error decreased from 0.83 to 0.69 m.

The four national taps of Singapore: a holistic approach to water resources management from drainage to drinking water

 Water resources in Singapore are managed following the principles of a closed loop hydrologic cycle by one agency, the Public Utility Board (PUB), which promotes its management philosophy through the Four National Taps of Singapore program. The four national taps are: water from local catchment areas; imported water (from Malaysia); reused water (known as NEWater); and desalinated water. Given the uncertainty of water imports, the remaining three national taps have become increasingly important and this paper begins with a general overview of the innovative programs implemented by PUB in support of these three taps. Stormwater runoff is captured from two-thirds of Singapore’s land area and stored in reservoirs for subsequent use. Stormwater management is an important component of the catchment area tap and extensive low impact development (LID) implementation has become a priority through the ABC (Active, Beautiful, Clean) Waters Program. Examples of several ABC Waters projects are discussed. NEWater currently supplies 30% of the country’s demand and this is projected to increase to 50% by 2060. NEWater plants take treated wastewater through the additional steps of microfiltration, reverse osmosis and ultraviolet treatment for use primarily in industry, although a portion also is blended into the municipal reservoirs. Singapore’s single desalination plant currently meets 10% of its demand, with a second plant to be completed in 2013 that will more than double production. Also discussed are the results of recently completed pilot projects related to stormwater management including testing of E. coli in runoff from high density residential areas, a blind taste test and survey on acceptance of NEWater, and a survey of Singaporean understanding about stormwater management issues.Water resources in Singapore are managed following the principles of a closed loop hydrologic cycle by one agency, the Public Utility Board (PUB), which promotes its management philosophy through the Four National Taps of Singapore program.

The impact of socially responsible human resource management on employees' organizational citizenship behaviour: the mediating role of organizational identification

Based on insights from social exchange and social identity theories, this paper examines the influence of three dimensions of socially responsible human resource management (SR-HRM), namely legal compliance HRM, employee-oriented HRM and general CSR facilitation HRM, on employees' organizational citizenship behaviour (OCB). Structural equation modelling of dyadic data collected from Chinese employees and their direct supervisors in three phases revealed that whilst organizational identification fully mediated the relationship between employee-oriented HRM and employee OCB, general CSR facilitation HRM had a direct effect on employee OCB. In contrast, legal compliance HRM neither influenced employee OCB directly, nor indirectly through organizational identification. The findings highlight the important but complex role played by SR-HRM in eliciting positive employee work outcomes, and contribute to our knowledge of the mechanisms underlying this relationship.

Potential for water-resource infrastructure to act as refuge habitat

Permanent sources of natural water are expected to decline in Mediterranean-climate regions under future climate change. Therefore, stable water bodies that act as refuge habitats will become increasingly important to the maintenance of freshwater biodiversity. Man-made water bodies such as those associated with water-resource infrastructure could contribute to the available refuge habitat but little is known about fish, zooplankton and frog assemblages in such water bodies. We quantified the diversity and abundance of fish, zooplankton and frogs that reside within raw water storages and water reclamation plants and compared them to assemblages from nearby natural water bodies over a total of 19 water bodies.Overall, the faunal assemblages within the man-made water bodies showed similarities to the nearby natural water bodies with very few differences found among the three water body types. Diversity of available substrates and of submerged and emergent macrophytes were the habitat variables best correlated with diverse faunal assemblages. This study suggests that the faunal assemblages within raw water storages and water reclamation plants resemble those found within nearby natural water bodies and that there is therefore potential for water-resource infrastructure to act as an important refuge habitat during drought. Furthermore, small changes in the management of these storages to maximise habitat diversity could increase the value of the refuge, complementing their role in water-resource delivery.

Control layer resource management in SDN-IoT networks using multi-objective constraint

Software Defined Networking (SDN) and Internet of Things (IoT) integration has thrown many critical challenges. Specifically, in heterogeneous SDN-IoT ecosystem, optimized resources utilization and effective management at the control layer is very difficult. This mainly affects the application specific Quality of Service (QoS) and energy consumption of the IoT network. Motivated from this, we propose a new Resource Management (RM) method at the control layer, in distributed SDN-IoT networks. This paper starts with reasons that why at control layer RM is more complex in the SDN-IoT ecosystem. After-that, we highlight motivated examples that necessitate to investigate new RM methods in SDN-IoT context. Further, we propose a novel method to compute controller performance. Theoretical analysis is conducted to prove that the proposed method is better than the existing methods.

Integrated natural resource management in Australia: the opportunity offered by a national coastal policy

Under the Australian Constitution the management (and planning) of Crown Land is a State and Territory Government responsibility. When this is considered in conjunction with the Offshore Constitutional Settlement, which affirmed that coastal waters out to three nautical miles (in general) offshore were also the responsibility of State and Territory Governments, then clearly coastal management in Australia is largely a State/Territory responsibility.

Beyond three nautical miles it is a different story. Under the United Nations Law of the Sea Convention (UNCLOS), which Australia ratified in October 1994, Australia claims jurisdiction out to 200 nautical miles and beyond (Wescott, 2000). These waters cover an area including the Antarctic claim of over 15 million square kilometres or twice the land area of Australia.

Hence in marine and coastal terms we have the national (Commonwealth) Government managing the oceans and seven State and Territory governments largely in charge of coastal management (coastal land and coastal waters). Heading "up river", State and Territory Governments plan and manage catchments.

Given the uncoordinated relationships between Australian coastal management policy and both catchment management policy and Australia's Ocean Policy (Commonwealth of Australia, 1998a and b), the Commonwealth Government's commitment to a "National Coastal Policy" presents an opportunity to progress the integration of natural resources management for the first time in decades.

The role of human resource management (HRM) in Australian-Malaysian joint ventures

This article examines human resource management (HRM) for successful Australian-Malaysian joint ventures (JVs), on the basis of survey data and case studies. The findings suggest that each phase of JV development had its own pattern of HR practices. Three phases of development were distinguished - initiation, transitional, and maturational. The first phase involved selecting, recruiting and training a skilled workforce and formulating rudimentary human resource policies. Cultural differences were most marked in this phase. The second phase, after three years of operation, involved evolution of human resource policies better suited to local conditions, and more polycentric management staffing. The final phase, after six years of operation, saw the development of a distinctive human resources system, and the minimisation of cultural differences as an operational issue. In this phase there was also a move to more geocentric management staffing.
