    Towards Secure and Legal E-Tendering

    Get PDF
    Tendering processes are considered to be a suitable mechanism for governments to fairly assign contracts for construction projects and procurement. The demand for efficiencies to be created in the process has resulted in a significant number of governments implementing e-tendering systems. E-tendering systems generally involve the submission of tender offer documents to a secure system hosted by the government (principal). An electronic environment presents obvious opportunities for collusion between principal and certain tenderers, fraud by tenderers and a minefield of legal uncertainties for fuelling protracted disputes. Critical examination of the security and legal requirements for e-tendering systems does not appear in the current literature. This paper identifies key security and legal issues to be addressed in the design of e-tendering systems, which may be included in e-procurement software, and proposes a new e-tendering architecture, using distributed trusted third parties which may be suitable for secure large scale operations such as the construction industry

    E-tendering in construction: time for a change?

    E-tendering is one of the information technology tools that has been highlighted by construction industry experts to assist in changing the industry’s culture and improving its processes. However the emergence of e-tendering in construction in the UK has been slow. This paper documents a questionnaire survey of quantity surveyors in northern England, identifying their views on different aspects of e-tendering, and providing an analysis of the perceived drivers and barriers to its implementation. Using a relative importance index, time and cost are confirmed as the two most significant perceived drivers in implementing e-tendering, while sustainability benefits are also recognised as important. The lack of experience and precedence in the legal realm is one of the main perceived barriers. The paper explores the impact of personal characteristics on attitudes towards e-tendering. Age and experience are particularly significant, with older and more experienced surveyors being more critical and negative than younger surveyors towards e-tendering. The analysis also identifies that the size and type of company affects attitudes with regard to electronic sharing of information and the related aspects of infrastructure and security. Smaller companies have more concerns with regard to security, while contractors’ quantity surveyors have much more concern over sharing information than clients’ consultants. Prior use also affects attitudes, with inexperienced users expressing more concerns over the use of e-tendering. The conclusion is that, amongst quantity surveyors, there is recognition of the benefits that e-tendering can bring about but that there are a number of barriers currently acting as a brake on the uptake of e-tendering

    Kesan pembelajaran koperatif terhadap pencapaian pendidikan alam sekitar dalam kalangan pelajar sekolah menengah rendah

    Get PDF
    Pembelajaran koperatif merupakan satu teknik pembelajaran yang melibatkan pelajar bekerjasama dalam satu kumpulan untuk mencapai matlamat tertentu. Dalam topik Pendidikan Alam Sekitar, pelajar didapati agak lemah dalam memahami sesuatu istilah dan tidak dapat mengaitkan topik dengan pengalaman serta persekitaran mereka. Sebelum ini, pengajaran dan pembelajaran lebih berpusatkan guru. Pembelajaran koperatif pula hanya melibatkan mata pelajaran yang menggunakan makmal atau bengkel. Kajian ini bertujuan untuk meninjau kesan pembelajaran berkumpulan terhadap pencapaian pelajar dalam Pendidikan Alam Sekitar melalui mata pelajaran Geografi. Bentuk kajian yang digunakan ialah kuasi-eksperimen yang dijalankan dengan menggunakan ujian pra dan ujian pasca ke atas kumpulan eksperimen dan kumpulan kawalan. Sampel kajian adalah dua kumpulan pelajar tingkatan 1 dari Sekolah Menengah Kebangsaan Luar Bandar di negeri Johor. Sampel kajian terdiri daripada 37 orang pelajar kumpulan eksperimen dan 35 orang pelajar kumpulan kawalan. Kumpulan eksperimen merupakan kumpulan yang menggunakan kaedah pembelajaran koperatif manakala kumpulan kawalan diajar tanpa pembelajaran koperatif. Instrumen kajian ialah ujian pencapaian, borang soal selidik, jadual pemerhatian dan temubual. Hasil kajian mendapati min pencapaian kumpulan eksperimen adalah tinggi iaitu 18.16 berbanding dengan min kumpulan kawalan, iaitu 13.91. Dapatan kajian menunjukkan terdapat peningkatan pencapaian bagi pelajar yang menjalani pembelajaran koperatif berbanding dengan pelajar yang tidak mengamalkan kaedah pembelajaran tersebut. Pelajar juga dapat menerima penggunaan pembelajaran koperatif dalam proses pengajaran dan pembelajaran. Kesimpulannya, pembelajaran koperatif bukan sahaja dapat meningkatkan hasil malah dapat meningkatkan kualiti proses pengajaran dan pembelajaran

    Critical success factors for e-tendering implementation in construction collaborative environments : people and process issues

    Get PDF
    The construction industry is increasingly engulfed by globalisation where clients, business partners and customers are found in virtually every corner of the world. Communicating, reaching and supporting them are no longer optional but are imperative for continued business growth and success. A key component of enterprise communication reach is collaborative environments (for the construction industry) which allows customers, suppliers, partners and other project team members secure access to project information, products or services they need at any given moment. Implementation of the stated critical success factors of the project is essential to ensure optimal performance and benefits from the system to all parties involved. This paper presents critical success factors for the implementation of e-tendering in collaborative environments with particular considerations given to the people issues and process factors

    Library purchasing consortia in the UK: activity, benefits and good practice.

    Following a brief introduction in Section 1, Section 2 sets out the operational context of library purchasing consortia. A range of key factors have shaped recent developments in the four LIS sectors under consideration (FE, HE, health and public libraries); some have exerted a common influence over all (e.g. information technology, European Commission purchasing directives, new central government, decline in bookfunds); some are sector-specific (e.g. purchasing arrangements, regional administrative frameworks, collaborative partnerships). The structure and markets of the book and periodical publishing industry in the UK are reviewed, with attention paid to historical as well as more recent practice that has had an impact on library supply. Although each component of the LIS purchasing consortia jigsaw displays individual characteristics that have evolved as a response to its own environment, the thread that links them together is constant change. Section 3 presents the results of a survey of identified library purchasing consortia in the four library sectors. It treats common themes of relevance to all consortia arising from information gathered by seminar input, questionnaire and interview. These include models of consortium operation, membership and governance, ‘typical’ composition of consortia in each sector, and links to analogous practice in other library sectors. Common features of the tendering and contract management process are elicited and attention paid to any contribution of procurement professionals. Finally, levels of consortium expenditure and cost savings are estimated from the published statistical record, which readily demonstrate in financial terms the efficiency of the consortial purchase model for all types of library in the United Kingdom. Section 4 presents the results of a survey of suppliers to libraries in the United Kingdom of books and periodicals, the two sectors most commonly represented in current contracts of library purchasing consortia. It sets out in some detail the operating context governing the highly segmented activities of library booksellers, as well as that pertaining to periodicals suppliers (also known as subscription agents). Detailed responses to questions on the effects of library purchasing consortia on suppliers of both materials have been gathered by questionnaire survey and selected follow-up interviews. Results are presented and analysed according to supply sector with attention given to the tendering process, current contracts under way, cross-sectoral clientele, and advantages and inhibitors of consortia supply. Further responses are reported on issues of how consortia have affected suppliers’ volume of trade, operating margins and market stability as perceived in their own business, the library supply sector and the publishing industry. Finally, overall conclusions are drawn and projections made as to future implications for both types of library suppliers. Section 5 synthesises findings, details enabling and inhibiting factors for consortia formation and models of best practice amongst consortia. The scope for cross-sectoral collaboration is discussed and found to be limited at present. Pointers are given for future activity

    Journal tendering for societies: a brief guide

    Get PDF
    Hundreds of societies publish journals in collaboration with publishers. Some may be considering how and whether to renegotiate or go out to tender. Some may be considering whether they can/should/wish to change the business model of the journal (e.g. by a move to Open Access). Other societies may be considering using an external publisher for the first time. This guide, based on our experience, is written for all of these. In their negotiations with publishers learned societies – especially smaller ones – may have difficulty articulating their requirements and assessing the publishers’ offerings. This is true where they wish to compare the newer models with typical "conventional" models, or simply compare different conventional offerings. The reasons are complex and include: * lack of knowledge of the publishing industry on the part of the society's executive staff (who cannot always find the time to acquire the knowledge); * the "author/research funder pays" models, which, whilst becoming more prevalent in the domains of science, technology, engineering and mathematics (STEM), appear (but may not actually be) rather less feasible in other domains. This guide draws on the experience of one learned society, the Association for Learning Technology (ALT), in reviewing the publishing arrangements for its journal Research in Learning Technology, between September and December 2010

    Relocalising the food chain: the role of creative public procurement

    Get PDF
    The conventional food chain presents a challenge to sustainable development, containing hidden costs such as health bills, environmental damage and economic costs to the rural economy. This report argues for the development of local food chains, which would bring the 'multiple dividend' of healthier diets, local markets for local producers, lower food miles and better understanding between producers and consumers. Barriers to the growth of local food chains include EU procurement regulations and UK local government legislation that prohibit explicit 'buy local' policies, health auditing conventions which neglect the health gains of nutritious food; catering cultures that are biased to a few large firms; tendering procedures that are too complex for small suppliers; and lack of logistical and marketing capacity on the part of local producers. Schools and hospitals should be the focus for a concerted local food campaign in the UK. A local food action plan is required to reform the regulatory regime, balance demand and supply, and make it easier for consumers, especially parents and children, to buy nutritious local food, including organic food

    Setting the market free: deregulation of the bus industry. 4th Smeed Memorial Lecture, 29th October 1987.

    [FIRST PARAGRAPH]Though he was not himself an economist, Reuben Smeed is well known to transport economists as the chairman of a committee which, in the early sixties, examined the use of congestion charges to obtain a rational use of scarce urban road capacity. (1) The Smeed report showed that in the absence of a proper road congestion pricing system there would be an excessive use of the private car, and, by implication, a sub optimum level of use of public transport. Although, to the best of my knowledge, Reuben never turned his mind to the issues of public transport regulation, the ready acceptance of public transport regulation and subsidy as second best proxies for road pricing in the late sixties and seventies was, I believe, founded on the Smeed logic
