Effects of state dependent correlations on nucleon density and momentum distributions

The proton momentum and density distributions of closed shell nuclei are calculated within a model treating short--range correlations up to first order in the cluster expansion. The validity of the model is verified by comparing the results obtained with purely scalar correlations with those produced by finite nuclei Fermi Hypernetted Chain calculations. State dependent correlations are used to calculate momentum and density distributions of 12C, 16O, 40Ca, and 48Ca, and the effects of their tensor components are studied.Comment: 16 pages, latex, 8 figures, accepted for publication in Phys.

A unitary correlation operator method

The short range repulsion between nucleons is treated by a unitary correlation operator which shifts the nucleons away from each other whenever their uncorrelated positions are within the replusive core. By formulating the correlation as a transformation of the relative distance between particle pairs, general analytic expressions for the correlated wave functions and correlated operators are given. The decomposition of correlated operators into irreducible n-body operators is discussed. The one- and two-body-irreducible parts are worked out explicitly and the contribution of three-body correlations is estimated to check convergence. Ground state energies of nuclei up to mass number A=48 are calculated with a spin-isospin-dependent potential and single Slater determinants as uncorrelated states. They show that the deduced energy- and mass-number-independent correlated two-body Hamiltonian reproduces all "exact" many-body calculations surprisingly well.Comment: 43 pages, several postscript figures, uses 'epsfig.cls'.

Disaster Management Education through Higher Education – Industry Collaboration in the Built Environment

Effectively responding to the current and dynamic construction labour market requirements is a major responsibility of higher education institutions (HEIs). HEIs aim to reduce the mismatch between what they deliver and what is required by the industry. Built environment professionals require continuous update of knowledge and education in order to effectively contribute to disaster management. However, the complex and multidisciplinary nature of disaster management education pose a challenge to the higher education institutions to make them more responsive to the industrial needs and to prepare the students for careers in disaster resilience. Adopting a lifelong learning approach would be appropriate for HEIs to maintain a through-life studentship and to provide disaster related knowledge and education on a continuous basis to respond to the labour market requirements. However, incorporating lifelong learning approach within the system of higher education is not easy and straightforward for HEIs. This is mainly because of the formal and bureaucratic nature of HEIs that acts as a barrier for providing effective lifelong learning education. In resolving this issue, HEIs are increasingly relying on the benefits associated with fostering close collaboration with external organisations such as industries, professional bodies and communities. In this context, this paper discusses the role of HEIs in providing disaster management education, the challenges associated with it, and the way of addressing the challenges through the higher education industry collaboration

Two-nucleon emission in the longitudinal response

The contribution of the two-nucleon emission in the longitudinal response for inclusive electron scattering reactions is studied. The model adopted to perform the calculations is based upon Correlated Basis Function theory but it considers only first order terms in the correlation function. The proper normalization of the wave function is ensured by considering, in addition to the usually evaluated two-point diagrams, also the three-point diagrams. Results for the 12C nucleus in the quasi-elastic region are presented.Comment: 7 pages, 4 Postscript figure

Factors in organisational environmental management system implementation – Developed vs. Developing country contexts

Country specificities and national cultures influence Environmental Management Systems (EMS) implementation and pro-environmental behaviour in organisations. Previous studies have focused on organisations in developed or emerging economies, creating a need to establish the extent to which findings are applicable to developing counterparts. This paper presents EMS implementation from a developing country perspective, reporting on EMS implementation factors (drivers, benefits, barriers) affecting Nigerian organisations’ pro-environmental behaviour, by analysing questionnaire responses from 136 Nigerian organisational respondents. Most commonly cited drivers were ‘environmental concern’ and ‘desire for improved organisational efficiency’. Key barriers were ‘cost of implementation/budget barriers’ and ‘regulatory agency bureaucracy’. Key benefits were ‘reduced environmental accidents and improved site safety’, ‘enhanced corporate image’ and ‘more efficient resource use’. To situate findings within a global construct, results were compared with previous studies in more developed economies. EMS implementation factors differed from those in more developed economies. Plausible explanations for differences are discussed

Relativistic Green's function approach to charged-current neutrino-nucleus quasielastic scattering

A relativistic Green's function approach to inclusive quasielastic charged-current neutrino-nucleus scattering is developed. The components of the hadron tensor are written in terms of the single-particle Green's function, which is expanded on the eigenfunctions of the nuclear optical potential, so that final state interactions are accounted for by means of a complex optical potential but without a loss of flux. Results for the (neutrino_mu, mu-) reaction on 16O and 12C target nuclei are presented and discussed. A reasonable agreement of the flux-averaged cross section on 12C with experimental data is achieved.Comment: 7 pages, 4 figure

Spectroscopy of formaldehyde in the 30140-30790cm^-1 range

Room-temperature absorption spectroscopy of formaldehyde has been performed in the 30140-30790cm^-1 range. Using tunable ultraviolet continuous-wave laser light, individual rotational lines are well resolved in the Doppler-broadened spectrum. Making use of genetic algorithms, the main features of the spectrum are reproduced. Spectral data is made available as Supporting Information

Editorial: work-life balance: a matter of choice?

Work–life balance has come to the forefront of policy discourse in developed countries in recent years, against a backdrop of globalization and rapid technological change, an ageing population and concerns over labour market participation rates, particularly those of mothers at a time when fertility rates are falling (Organization for Economic Co-operation and Development [OECD], 2004). Within the European Union the reconciliation of work and family has become a core concern for policy and encouraged debate and policy intervention at national levels

Electroinduced two-nucleon knockout and correlations in nuclei

We present a model to calculate cross sections for electroinduced two-nucleon emission from finite nuclei. Short-range correlations in the wave functions and meson-exchange contributions to the photoabsorption process are implemented. Effects of the short-range correlations are studied with the aid of a perturbation expansion method with various choices of the Jastrow correlation function. The model is used to investigate the relative importance of the different reaction mechanisms contributing to the A(e,e$'$pn) and A(e,e$'$pp) process. Representative examples for the target nuclei $^{12}$C and $^{16}$O and for kinematical conditions accessible with contemporary high-duty cycle electron accelerators are presented. A procedure is outlined to calculate the two-nucleon knockout contribution to the semi-exclusive (e,e$'$p) cross section. Using this technique we investigate in how far semi-exclusive (e,e$'$p) reactions can be used to detect high-momentum components in the nuclear spectral function.Comment: 51 pages, Latex, uses epsf.sty and elsart.sty, 17 figures (in eps format
