  • Substituent Effects in Benz[<i>a</i>]anthracene Carbocations:  A Stable Ion, Electrophilic Substitution (Nitration, Bromination), and DFT Study

    computed relative energies by DFT. Charge delocalization paths in the resulting carbocations were deduced based on the magnitude of Δδ13C values. For the thermodynamically more stable C-12 protonated carbocations, the charge delocalization path is analogous to those derived based on computed NPA charges for the benzylic carbocations formed by 1,2-epoxide (bay-region) and 5,6-epoxide (K-region) ring opening

  • Partnering for e-government: Challenges for public administrators
    作者:John Langford、Yuonne Harrison
    DOI:10.1111/j.1754-7121.2001.tb00898.x

    Abstract: Governments around the world are spending huge sums of money implementing electronic government. Public‐private partnerships with information and communication technology firms have emerged as the vehicle of choice for implementing e‐government strategies. Concerns are raised about the capacity of governments to manage these complex, multi‐year, often multi‐partner relationships that involve considerable sharing of authority, responsibility, financial resources, information and risks. The management challenges manifest themselves in the core partnering tasks: establishing a management framework for partnering; finding the right partners and making the right partnering arrangement; the management of relationships with partners in a network setting; and the measurement of the performance of e‐government partnerships. The article reviews progress being made by governments in building capacity to deal with these core partnering tasks. It concludes that many new initiatives at the central agency and departmental/ministry level seem designed to centralize control of e‐government projects and wrap them in a complex web of bureaucratic structures and processes that are, for the most part, antithetical or, at best, indifferent to the creation of strong partnerships and the business valuethat e‐government public‐private partnerships promise.
