Economic Efficiency and Takeover Bid Regulation

In recent years a number of scholars have debated the economic efficiency of takeover-bid legislation and of permissible defensive tactics taken by the management of takeover target corporations. This article reviews and comments on this literature and draws attention to a number of empirical questions raised by the debate. It concludes that the important outstanding issues are: i) the degree to which takeover rules interfere with the deterrence of management inefficiency, and ii) the cost of allocating assets to their most highly-valued uses through competitive bidding as opposed to the likelihood and cost of retransfers of assets after takeovers without competitive bidding

Apollo experience report: Lunar module environmental control subsystem

A functional description of the environmental control subsystem is presented. Development, tests, checkout, and flight experiences of the subsystem are discussed; and the design fabrication, and operational difficulties associated with the various components and subassemblies are recorded. Detailed information is related concerning design changes made to, and problems encountered with, the various elements of the subsystem, such as the thermal control water sublimator, the carbon dioxide sensing and control units, and the water section. The problems associated with water sterilization, water/glycol formulation, and materials compatibility are discussed. The corrective actions taken are described with the expection that this information may be of value for future subsystems. Although the main experiences described are problem oriented, the subsystem has generally performed satisfactorily in flight

Green investment strategies: a positive force in cities

Deterioration of urban neighborhoods is known to induce out migration, but how well do public investments to reverse decline actually work? To evaluate Philadelphia’s greening investment, researchers measured property buyers’ willingness to pay more—and found that greening works.Community development

A systematic literature review of university-industry partnerships in engineering education

Over the last few decades, a wide range of works have featured studies documenting successful pedagogic collaborations in the form of university-industry partnerships in engineering education. In light of this, we conducted a systematic literature review of these studies centred around five key research questions: (a) purposes of universityindustry collaborations, (b) theories used to guide such work, (c) types of methods employed, (d) evidence-based best practices identified and (e) areas of future work to be explored. Publications were selected for inclusion by screening and appraising results obtained from databases and keywords refined through a scoping study. We conclude from our findings that future studies would benefit from better alignment with literature or theoretical frameworks and specific robust methods. Additionally, early and middle years of undergraduate engineering programs offer underutilised opportunities for partnership, in line with designing a more futures-focused educational curriculum

Study of CeO2 and its native defects by density functional theory with repulsive potential

We investigated the native point defects in CeO2 by the density functional (DFT) +U method, and using a non-linear core-corrected norm-conserving Ce pseudopotential. We find the neutral oxygen vacancy (VO 0) in CeO2 to have a very low formation energy of only 0.39eV in the Opoor limit. It is a deep donor with negative U behavior, only stable in its neutral and doubly positive states. The anion Frenkel defect is found to be the lowest energy disorder defect, with a formation energy of only 2.08eV per defect site. These low formation energies arise from the improved transferability of our Ce pseudopotential for its +3 and +4 valence states. The negative U behavior of VO leads to excellent photo-catalytic behavior, while the low formation energy of the anion Frenkel defect leads to a superior oxygen storage-and-release capability.All computing facilities and calculation resources receive funding from the Research Grant Council, University Grants Committee of the HKSAR government.

The screening effects of the screened exchange hybrid functional in surface systems: A case study on the CO/Pt(111) problem

The screened exchange (sX) hybrid functional has been widely used in computational material science. Although it has widely been studied in bulk systems, less is known about its functional behavior in surface systems which are crucial to many technologies such as materials synthesis and nano-electronic devices. Assessing the screening dependent functional behaviors in the surface systems is therefore important for its application in such systems. In this work, we investigate the screening effects of the sX in CO adsorption on Pt(111) surface. The differences between the sX and Heyd-Scuseria-Ernzerhof (HSE06) hybrid functionals, and the effects of screening parameters are studied. The screening has two effects: first, the HOMO-LUMO gap is screening dependent. This affects the site preference most significantly. In this work, atop adsorption of CO/Pt(111) is predicted by the hybrid functionals with screened exchange potential. The sX(1.44) gives the largest HOMO-LUMO gap for the isolated CO molecule. The adsorption energy difference between the atop and fcc site is also the largest by the sX(1.44) which is explained by the reduced metal d states to the CO 2π* state back-donation, with stronger effect for the fcc adsorption than for the atop adsorption; second, the adsorption energy is screening dependent. This can be seen by comparing the sX(2.38) and HSE06 which have different screening strengths. They show similar surface band structures for the CO adsorption but different adsorption energies, which is explained by the stronger CO 5σ state to the metal d states donation or the effectively screened Pauli repulsion. This work underlines the screening strength as a main difference between sX and HSE06, as well as an important hybrid functional parameter for surface calculation.The author J.R. and H.L. thank EC project GRAFOL, CP-IP 285275 and EPSRC (grant reference no.

Towards Identifying Core Computational Literacy Concepts for Inclusion in a First-year General Engineering Course

In this paper, we describe an exploratory study to support efforts in revising first-year courses required for engineering students. It is common to include some form of introductory programming or spreadsheet computation topics in first-year courses. The inclusions of these topics is ostensibly to provide foundational computational skills needed in later courses. However, there are many challenges associated with teaching and learning these skills, the least of which is selecting which skills to include in the finite time allotted for a first-year introductory course that may also be tasked with teaching foundational problem solving and professional skills. This study is the first stage towards identifying a core set of skills for inclusion that would be relevant for most first-year students
