How do public-sector workers assess their prospects for retirement? This article examines retirement planning at a public university in South Florida, where contemporary demographics mirror the nation's expected demographics in 2010. Like their private sector counterparts, our respondents believe quality of life at retirement will be favorable. Yet many respondents appear to be under-saving for retirement and fail to recognize that part-time employment is likely to be an integral part of their retirement experience. As expected, socioeconomic factors, particularly education, gender, and ethnicity, play a significant role in determining retirement planning and perceived quality of life in the “Golden Years.” Investment literacy is limited among many of our respondents, particularly females and minorities. This is critical in light of increased reliance on defined contribution pensions and possible reforms in Social Security.

Surveys, from an American perspective, the existing literature on economic explanations of the behaviour of universities and scholars. The modern literature is put in historical perspective introduced by a brief discussion of the positions of two of the earliest and most distinguished contributors to the literature: Adam Smith and Max Weber. Discusses the human capital and implicit contracts literatures of the behaviour of scholars, the latter elaborated in terms of the issue of tenure. The most common theoretical economic analysis of the university is the view that it is best thought of as a non‐profit organization. Discusses variants of this view, with special attention to the literature on rent‐seeking in academe. Goes on to the empirical literature on the economics of academe in the areas of academic institutions, academic earnings functions, the earnings and status of minority scholars and academic production functions. Briefly considers the relevance of the current literature to the Althoff system, suggesting that Althoff′s able, trusted advisers, and his system of institutes, may have allowed him to avoid several inefficiences that have been identified by economists as present in other academic institutions. Although the centralization of decision making in the hands of one decision maker may be efficient if the decision maker is exceptionally able, more commonly the most efficient system will be a decentralized system that allows for greater diversity and competition. Concludes with a discussion of how hypotheses on the efficiency (and fairness) of various aspects of the Althoff system could, in principle, be tested.

The purpose of this paper is to extend the penalty concept to treat partial slip, free surface, contact and related boundary conditions in viscous flow simulation.

The penalty partial‐slip formulation is analysed and related to the classical Navier slip condition. The same penalty scheme also allows partial penetration through a boundary, hence the implementation of porous wall boundaries. The finite element method is used for investigating and interpreting penalty approaches to boundary conditions.

The generalised penalty approach is verified by means of a novel variant of the circular‐Couette flow problem, having partial slip on one of the cylindrical boundaries, for which an analytic solution is derived. Further verificationis provided by consideration of viscous flow over a sphere with partial slip on the surface, and comparison of numerical and classical solutions. Numerical studies illustrate the versatility of the approach.

The penalty approach is applied to some different boundaries: partial slip and partial penetration with no/full slip/penetration as limiting cases; free surface; space‐ and time‐varying boundary conditions which allow progressive contact over time. Application is made to curved and inclined boundaries. Sensitivity of flow to penalty parameters is an avenue for continued research, as is application of the penalty approach for non‐Newtonian flows.

This is the first work to show the relation between penalty formulation of boundary conditions and physical boundary conditions. It provides a method that overcomes past difficulties in implementing partial slip on boundaries of general shape, and which handles progressive contact. It also provides useful benchmark problems for future studies.

H₂O, CO₂ and CO are three main species in combustion systems which have high volume fractions. In addition, soot has strong absorption in the infrared band. Thus, H₂O, CO₂, CO and soot may take important roles in radiative heat transfer. To provide calculations with high accuracy, all of the participating media should be considered non-gray media. Thus, the purpose of this paper is to study the effect of non-gray participating gases and soot on radiative heat transfer in an inhomogeneous and non-isothermal system.

To solve the radiative heat transfer, the fluid flow as well as the pressure, temperature and species distributions were first computed by FLUENT. The radiative properties of the participating media are calculated by the Statistical Narrow Band correlated K-distribution (SNBCK), which is based on the database of EM2C. The calculation of soot properties is based on the Mie scattering theory and Rayleigh theory. The radiative heat transfer is calculated by the discrete ordinate method (DOM).

Using SNBCK to calculate the radiative properties and DOM to calculate the radiative heat transfer, the influence of H₂O, CO₂, CO and soot on radiation heat flux to the wall in combustion system was studied. The results show that the global contribution of CO to the radiation heat flux on the wall in the kerosene furnace was about 2 per cent, but that it can reach up to 15 per cent in a solid fuel gasifier. The global contribution of soot to the radiation heat flux on the wall was 32 per cent. However, the scattering of soot has a tiny influence on radiation heat flux to the wall.

This is the first time H₂O, CO₂, CO and the scattering of soot were all considered simultaneously to study the radiation heat flux in combustion systems.

The purpose of this paper is to present a new approach of evaluation of the absorption line black body distribution function (ALBDF) for a mixture of gases. Currently published correlations, which are used to reproduce the ALBDF, treat only single gases.

A discrete form of the ALBDF is generated using line by line (LBL) calculations. The latest spectroscopic database HITEMP 2010 is used for the generation of the absorption coefficient histogram, which is cumulated later in order to produce a tabulated form of the ALBDF. The proper orthogonal decomposition (POD) statistical method is employed for the reproduction of the ALBDF. Interpolation property of the POD allows to reproduce the ALBDF for arbitrary gas mixture parameters.

POD proved to possess optimal interpolation properties. Results obtained by using POD are in very good agreement with LBL integration.

One have to be aware that the model generated with the POD method can be used only within the range of parameters used to build the model. The POD does not perform any property extrapolation. The model is limited to a mixture of two gases, namely CO₂ and H₂O. Expanding the number of gases used in the mixture may lead to a relatively large matrix system, which is difficult to process with the POD approach.

The presented approach can be used to produce absorption coefficients values and their weights, which can be applied in the gas radiative properties description using the weighted sum of gray gas (WSGG) concept. The proposed model can be used with any radiative transfer equation solver which employs the WSGG approach.

For the first time, radiative properties of gas mixtures are reproduced using the POD approach.

Policy requires that those with complex long‐term needs be offered case management, a primary care led service dependent on local health and social care resources. This paper explores the arrangement of networks for a number of case management services, using data from a postal questionnaire.

Since the appearance of Simon Rottenberg's seminal paper on the baseball players' labour market in the Journal of Political Economy (1956), the literature on the economics of professional team sports has increased rapidly, fuelled by major changes in the restrictive rules which had pervaded these sports, themselves a consequence of battles in the courts and the collective bargaining arena. These changes have not been limited to North America, to which most of the literature relates, but also apply to Western Europe and Australia in particular. This monograph surveys this literature covering those various parts of the world in order to draw out both theoretical and empirical aspects. However, to argue that the existence of what is now an extensive literature “justifies” such a survey on professional team sports clearly begs a number of questions. Justification can be found in at least two major aspects.

The Florida electorate passed Amendment One on January 29th, 2008. The portability provision of this Amendment allows homestead owners to transfer the difference between assessed value and estimated market value of their current homestead property to their new property. Since passage, there has been limited and declining utilization of the portability provision. This paper explores whether the accrued tax savings due to the property assessment limit provide sufficient incentive for homesteaders to move by examining aggregated utilization of the portability provision among counties. Based on a panel regression using 67 counties from 2008 to 2012, our findings indicate the portability provision has had limited impact on Florida's depressed housing market and only a small number of well-educated and white homesteaders have availed themselves of this mechanism.

Function libraries, and indeed the majority of organisations, especially those operating on a commercial basis or utilising public funds, consist of material and human structures. The leaders of the human structure utilise personnel and materials in the pursuit of certain goals. Brech itemises four main elements in this process of planning and regulating enterprise activities.
