Strategic implications of e-business in the construction industry

Chen, Yong J. January 2012 (has links)
Electronic Business (e-Business) is recognised as being able to help organisations in the construction industry to achieve competitiveness and substantial benefits. However, the uptake of e-business in the construction industry has been relatively limited and ineffective. Previous research covers the body of knowledge about how to identify the value of e-business once it has been created or how to identify the capabilities that can create value. There is no guidance available to help organisations to maximise their leverage by investing intelligently and matching the size of their demand for e-business solutions to the size of the market they plan to supply. This research aims to identify the strategic e-business needs and requirements of organisations in the construction industry; it helps them to scan or position their current situation, and provide a holistic approach to assist them in developing an executable e-business strategy. In order to achieve the aim and the formulated objectives, a multi-methodological research design and a pragmatic mixed-methods approach, involving a combination of both quantitative and qualitative datasets, were adopted to investigate the e-business practices of organisations in the industry. These include an exploratory investigation (an industry survey with 250 industry organisations), and an explanatory investigation (four case studies with specific industry end-user companies). The collected data was analysed and problems were identified; the elements for a holistic approach to manage e-business implementation emerged. Subsequently, a Strategic e-Business Framework was developed to provide a holistic approach for organisations in the construction industry to plan, execute and review their e-business strategies. The Framework enables organisations to consider the medium term (three to five years), long-term (over five to ten years), and emergent needs to derive business value. The key features of the Framework include six phases and phase gates, five functional factors, and 23 activities. The six phases include Analyse Situation, Establish Vision, Define Critical Success Factors (CSFs), Develop Action Plan, Implement Action Plan, and Review Strategy. The phases were defined to guide the IT leaders in carrying out consistent e-business planning. The outputs of each phase (phase gates) were defined to assist IT leaders in the review of procedures during their e-business implementation. The functional factors include management, people, process, technology and external environment. The factors were identified to address every facet of an organisation, and obtain collaboration efforts from both internal and external. They also ensure organisations have the opportunities to improve capabilities in these areas, and make them ready for immediate e-business implementation. Five groups of people or teams were assigned to the activities. The five groups were the Senior Management Board, IT Managers and their teams, Middle Level Management, Lower Level Management and other End-users, and external collaborators. The activities were categorised in order to provide a basis for organisations to utilise their resources, specifically human resource. Finally, a feedback loop was defined to enable the Framework to act as a cycle for going through repeatedly, which makes the continuous improvement of e-business implementation possible within organisations and provides a learning and feedback function that ensures lessons to be learned from past e-business implementation. The evaluation of the Framework was conducted via six structured interviews with industry practitioners. The findings indicated that the industry practitioners welcomed the Framework and considered it as a positive step towards e-business management.

The role of internal stakeholders and influencing factors during the phases of e-government initiative implementation

Al-Rashidi, Hajed January 2013 (has links)
Governments around the globe were actively implementing e-government initiatives in the past two decades. However, the majority of e-government initiatives fail in achieving their objectives before, during or after implementation. This study is addressing the problem, e-government initiatives are still more failure than success. Literature indicates differing models that analyse various stages, stakeholders and factors influencing e-government implementation in the public sector. Yet, these models do not explore in particular the important roles and responsibilities of internal stakeholders and influencing factors during different phases of the implementation cycle of the e-government initiative. There is a need for a framework that guides the e-government initiative implementation internally. To achieve the aim of this research, this study should empirically investigate "managing e-government initiative implementation." Consequently, this thesis results in research that contributes towards successful e-government initiative implementation based on empirical data derived from three case studies. The practical parts of the research are three case studies on e-government initiative implementation, which are analysed using an interpretive and qualitative research approach. Besides document analysis and observation, interview was the main method to collect empirical data for this study. For an accurate result, only managers and above level are selected and interviewed. The study examines the proposed framework in three government organizations in the State of Kuwait by using a qualitative, interpretive, multiple case study research strategy. As a result, this thesis is proposing a framework that can be used to enhance the implementation process of e-government initiative throughout the different phases of the implementation cycle, and contributes to the body of knowledge by extending the literature. The stakeholders, factors and implementation phases are mapped together to ease understanding the implementation process of e-government initiative implementation across the public organizations. The study concludes by identifying internal stakeholders, factors, and providing a holistic framework for e-government initiative implementation. The findings of this research are useful for internal stakeholders in the field, as it enables them to gain a better understanding of their own roles and responsibilities. Moreover, researchers in similar fields may find this work useful as a way to approach the study of e-government initiative implementation.

A Framework Supporting Development of Ontology-Based Web Applications

Tankashala, Shireesha 17 December 2010 (has links)
We have developed a framework to support development of ontology based Web applications. This framework is composed of a tree-view browser, an attribute selector, the ontology persistence module, an ontology query module, and a utility class that allows the users, to plug-in their own customized functions. The framework supports SPARQL-DL query language. The purpose of this framework is to shield the complexity of ontology from the users and thereby ease the development of ontology based Web applications. Having high quality ontology and using this framework, the end-users can develop Web applications in many domains. For example, a professor can create highly customized study guides; a domain expert can generate the Web forms for data collections; a geologist can create a Google Maps mashup. We have also reported three ontology-based Web applications in education, meteorology and geographic information system.

Scraping Dynamic Websites for Economical Data : A Framework Approach

Legaspi Ramos, Xurxo January 2016 (has links)
Internet is a source of live data that is constantly updating with data of almost anyfield we can imagine. Having tools that can automatically detect these updates andcan select that information that we are interested in are becoming of utmost importancenowadays. That is the reason why through this thesis we will focus on someeconomic websites, studying their structures and identifying a common type of websitein this field: Dynamic Websites. Even when there are many tools that allow toextract information from the internet, not many tackle these kind of websites. Forthis reason we will study and implement some tools that allow the developers to addressthese pages from a different perspective.

Development and evaluation of a professional development framework for pharmacy undergraduate students to support their learning in professional practice

Stupariu, Ioana January 2012 (has links)
The roles of pharmacists have changed in the last decades requiring pharmacists to keep up with, and even anticipate, the changes in practice to continue to be competent healthcare professionals. Competency or professional development frameworks have been developed and validated to support pharmacists with their learning and development. However, such a tool has not been developed for pharmacy undergraduate students and it is sensible to think that such a framework might also help pharmacy students in their learning and competency development. Thus, the aim of this research was to identify competencies required of pharmacy undergraduate students and to develop, and evaluate the use of, a professional development framework for these students. A mixed methods approach was adopted in the two-phased study. A cross-sectional design was employed in the first phase. Literature on pharmacy students’ competencies was reviewed and a series of workshops, focus groups and interviews with pharmacy students and academics, and stakeholders in pharmacy were conducted to identify the competencies required of pharmacy students during their degree and to develop the framework. The findings of previous rounds of data collection fed into the subsequent rounds. After five iterations 17 competencies were identified and divided in two clusters: Professional; and Delivery of Patient Care Competencies. A longitudinal design was used in the second phase. The use of the framework was evaluated with third and fourth year pharmacy students who self-assessed their competencies three times in two schools of pharmacy over the academic year of 2009-2010. The students’ self-assessed competencies increased over the year and correlated positively with their examination results and perceived self-directedness towards learning. This research provides evidence that the framework captures pharmacy undergraduate students’ development of their competencies during the academic year based on their self-assessed competence. Thus, the framework can be used as a self-assessment tool to support their learning.

Carbon dioxide absorption in metal organic frameworks

Gao, Min January 2015 (has links)
With the emission of carbon dioxide (CO2) becoming an international worry due its role in climate change, solutions such as CO2 capture and storage technologies are needed to decrease the emissions. The main proportion of CO2 gas emissions is from fossil fuel combustion in a range of industries, including power generation. To develop the CO2 capture system for these operations, new materials are needed for CO2 capture. Metal-organic framework (MOF) materials have porous crystal structures containing organic molecules (organic ligands) linked to each other by metalcontaining nodes. The large internal surface area can be exploited for the adsorption of small gas molecules, and for this reason MOFs may be ideal candidate materials for CO2 capture and gas separations. Thousands of MOF materials have been reported, with different combinations of the ligands and metals and with the capability of forming many different network topologies. Experimentally it is very difficult to study the gas absorption dynamics, interaction and gas adsorption capacity for the large number of materials. This problem can be solved by simulations. The aim of the thesis is to develop a systematic simulation method to screen the MOF properties and CO2 adsorption capacity and interaction dynamics at different environment. The molecular dynamics (MD) method with parameterised force fields was used to study the interactions between CO2 molecules and one class of the MOFs, zeolitic imidizolate frameworks (ZIFs) with zinc as the metal cation. To develop the model, the atom charges have been developed by using the distributed multipole analysis (DMA) method based on ab initio DFT calculations for molecules and clusters. The intermolecular forces were developed by fitting against the MP2 calculations of small clusters of the metal cations and molecular ligands. In order to evaluate the models I simulated the gas-liquid coexistence curve of CO2 and showed that it is consistent with experiments. I also simulated the pure ZIF structures on changing both temperature and pressure, demonstrating the stabilities of the structures but also showing the existence of displacive phase transitions. I have used this approach to successfully study CO2 absorption in a number of ZIFs (from ZIF-zni, ZIF-2, ZIF-4, ZIF-8 and ZIF-10) using MD. The gas absorption capacity and dynamics have been investigated under 25 bar and 30 bar, 200 , showing a promising uptake of CO2. The results have shown that CO2 capacity is mainly determined by the pore sizes and pore surfaces, in which a higher capacity is associated with a higher pore surface. The intermolecular distance of CO2 inside the pores and channels have been investigated in the saturation state. It has been shown that the distance is approximately 4 Å. The attraction force is from the interaction between CO2 and the imidazolate ligands. In addition, the systematic studies of the saturated ZIF system gave the minimum diameters for CO2 adsorption which is approximately 4.4 Å. This interaction has caused the gate opening effects, with the imidazolate ligands being pushed to be parallel to the CO2 molecules and opening up to allow more gas molecules go through the channels that connect the pore structures. This gate opening effect also explains the phase transition in ZIF-10 caused by CO2 molecules in our simulation, and can be applied to predict phase transitions in other materials with similar structure such as ZIF-7 and ZIF-8. The dynamics have also shown that the gas diffusion velocity is determined by the pore structure as well and by the accumulated layers of CO2 on the surface prior to being pushed in toward the centre of the material layer by layer. The de-absorption processes have also been studied in these materials by decreasing the pressure from 25 bar to 1 bar under at same temperature. The results indicate that the de-absorption is a reverse process of absorption. The structure of ZIF-10 went through a phase transition induced by CO2 recovered after the guest molecules had been released. The de-absorption can be accelerated by increasing the temperature.

Consumer protection in the banking sector : the need for reform to protect bank consumers in Nigeria

Uzokwe, Henry Chilewubeze January 2017 (has links)
The protection of consumers of financial services has attracted a lot of debates following the global financial crisis of 2007 to 2009. As a result, there have been series of reforms in a number of jurisdictions across the globe. Despite this development some countries still lag behind and Nigeria is no exception. This study examines the problems of consumer protection in Nigeria, with specific reference to the bank consumers. The aim is to consider whether the Nigeria consumer protection regime provides "sufficient protection to bank consumers and whether it should be reformed". The study also focuses on the role of the Central Bank of Nigeria (CBN) in consumer protection, its dispute resolution mechanism and the practical challenges. The test of sufficiency will be analysed and discussed, using 'consistency', 'efficiency' and 'accessibility' in order to illustrate the existing weaknesses in resolving consumer dispute. The approach in this study is doctrinal analysis. In all, the findings suggest that there is need, to reform the consumer protection regime in the banking sector and enforce laws which will address issues highlighted in the study to enable the users of banking services in Nigeria to obtain an appropriate level of protection through regulatory processes. This study, therefore, also provides a comparative analysis between United Kingdom and Nigeria, using current consumer protection framework in the United Kingdom in making proposals for the needed reforms in Nigeria. The study thus concludes with the recommendation that the current Nigerian consumer protection regime does not offer adequate protection; hence protecting consumers require a holistic approach which includes effective consumer protection framework, enforcement, coordination and cooperation from different stakeholders.
