Dreaming of Data: The Library's Role in Supporting e-Research and Data Management

The increasing focus on eResearch comes with an increasing focus on data management, data use, data sharing and data re-use. This presents a challenge to research institutions as they decide where the responsibility for all of this data lies. Libraries have long had a role in managing text-based materials in the digital environment, as can be seen by the rapid take up of institutional repositories and many library ventures into electronic publishing of different kinds. There are many who see that the library has a significant role to play here, and several Australian university libraries are already actively engaged in data management in its broadest sense, as are state libraries, the National Library and others. This paper examines the capabilities and skills required within research institutions as they implement the organisational and cultural change which will be needed. It is based on two surveys conducted in 2007. The Skills for eResearch Project undertaken by APSR included interviews and surveys of a range of people associated with the eResearch agenda. The findings suggest that the provision of appropriately skilled personnel will be key factor in moving forward, and that the skills required go far beyond the technical. At the same time, there are currently many barriers to the conduct of eResearch and these will need to be addressed in order to develop new services supporting institutional capability. The Data Management Survey was conducted by three Australian universities in late 2007 and looked at the data management practices of researchers. The results show both positives and negatives, and point towards areas for improvement

The Eigenvalue Spectrum of the Fermion Matrix in Lattice Higgs Systems

In the first part of this thesis we consider the performance of various block algorithms for the inversion of large sparse matrices. By computing the eigenvalue spectra of the matrices under consideration we are able to directly relate the performance of the algorithms to the difficulty of the calculation. We find that the block Lanczos algorithm is superior to all others considered for the inversion of the Kogut Susskind fermion matrix. Furthermore we investigate the performance of the block Lanczos algorithm on matrices constructed to have specific eigenvalue spectra. From this study we are able to make quantitative predictive statements about the number of iterations that the algorithm will take to converge given the form of the eigenvalue spectrum of the matrix whose inversion is attempted. The rest of this thesis is concerned with lattice Higgs systems. Specifically we study a model where staggered fermions are coupled to Ising spins via an on-site Yukawa term with coupling constant y. This is a very simple model that seems to embody most of the relevant phenomena observed in more complicated systems. Most importantly there are two symmetric regions PM1 and PM2 where the renormalised fermion mass my is non-zero for large y in the PM2 region despite the scalar field having zero expectation value. We study the model in the quenched approximation and by examining the distribution of the eigenvalues of the fermion matrix M in the complex plane we qualitatively explain the features of the model as being due to the transition of eigenvalues from the imaginary to the real axis via the origin as y is increased. An approximate method for calculating mf from the value of a fermion condensate is developed and we reproduce the values for mf obtained by other authors who calculate it using the standard method involving the fermion propagator. However, our method has the advantage that it is applicable on very small volumes where the propagator definition breaks down. We investigate the behaviour in the quenched infinite volume limit by evaluating the low lying eigenvalues of the matrix A+M. We show that the small eigenvalues observed in the spectrum of M at intermediate y on finite lattices imply that there is a finite density of zero modes in the infinite volume limit. By performing dynamical simulations on a small lattice we determine the phase diagram of the model and demonstrate the validity of mean field calculations of the phase boundaries. From calculations of mf we identify the PM1 and PM2 phases. It is shown that the inclusion of fermion dynamics eliminates the small eigenvalues of M present in the quenched model and as y is increased the eigenvalues now transfer from the real to imaginary axis via a path avoiding the origin. It is only by using the block Lanczos algorithm that simulations in certain regions of the phase plane are feasible, and only by our method of considering a fermion condensate can we calculate mf on such a small volume

Pomerons and Lattices: a Progress Report

We report on some attempts to use lattice QCD to investigate topics in strong interactions phenomenology which are usually interpreted in terms of soft Pomeron exchange.Comment: Talk presented at LAT96, 3 pages, Latex, one style file and 2 PostScript pictures include

PENGARUH MOTIVASI DAN KOMPENSASI TERHADAP KEPUASAN KERJA PADA KARYAWAN PRODUKSI DI PT. GALIC ARTABAHARI

ABSTRACT Henty Retris Pangesti, 2015; The Influence Of Motivation And Compensation To Production Employee Job Satisfaction At PT. Galic Artabahari. Skripsi: Jakarta, Human Resource Management Concentration, Management Study Program, Department of Management, Faculty of Economics, State University of Jakarta. The purpose of the research are:.. 1)To describe about motivation, compensation and production employee job satisfaction PT. Galic Artabahari. 2)To determine whether there is an influence of motivation on production employee job satisfaction PT. Galic Artabahari. 3)To determine whether there is an influence of compensation on production employee job satisfaction PT. Galic Artabahari. 4)To determine whether there is influence between motivation and compensation on production employee job satisfaction PT. Galic Artabahari. 5)To find about how far the contribution from motivation and compensation to production employee job satisfaction PT. Galic Artabahari. This research is taken 110 production employee in PT. Galic Artabaharii. The techniques of data collection used survey method by distributing questionnaires, which are then processed using SPSS 21.0. The research using descriptive and explanatory analysis. Data account which used is SPSS 21.0. The results of the regression indicate that there is positive influence and significant between motivation to job satisfaction and there is positive influence and significant between compensation to job satisfaction. Motivation and compensation simultaneously positive influence and significant to job satisfaction through Fcount >F (44.601>3.08) and significance value (0.000 < 0.05). This research has figured out the score of motivation and compensation on job satisfaction is 0,443 or 44,3% through the result of R2 value while the rest is 55,7 % is influenced by the other factors. Keywords: Motivation, Compensation and Job Satisfactio
