Abstract

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.

Abstract

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.

Abstract

Purpose

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.

Design/methodology/approach

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).

Findings

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.

Originality/value

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.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Research limitations/implications

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.

Originality/value

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.

Abstract

Xavier University of Louisiana has a national reputation for producing science, technology, engineering, and mathematics (STEM) graduates who go on to obtain MD and PhD degrees. According to a 2013 National Science Foundation report, Xavier is ranked first in producing African American graduates who go on to receive life sciences PhD degrees, fifth in the nation in producing African American graduates who go on to receive science and engineering PhD degrees, and seventh in producing African American graduates who go on to receive physical sciences PhD degrees. Xavier is currently third among the nation’s colleges and universities in the number of African American graduates enrolled in medical school, according to data compiled by the Association of American Medical Colleges, and ranked first in the number of African American alumni who successfully complete their medical degrees. The success of Xavier’s graduates is due to a combination of university-based student support initiatives and externally funded programs, in particular, the Building Infrastructure Leading to Diversity (BUILD), Maximizing Access to Biomedical Research Careers (MARC) U*STAR, and Research Initiative in Scientific Enhancement (RISE) programs. These three programs, funded by the Training, Workforce Development, and Diversity (TWD) Division at the National Institutes of Health (NIH), offer select trainees undergraduate research opportunities, support mechanisms, and a variety of activities designed to improve their potential for success in graduate school. The BUILD, MARC U*STAR, and RISE programs work closely together and with the University to leverage the resources provided by each in order to provide the best experience possible for their students with a minimum of redundancy of effort. This chapter focuses on the program components and how the programs work together.

Abstract

Corporate foundations – entities established to regularize corporate giving at an arm’s length removed from the firm – command substantial resources, root companies in the nonprofit sectors of their host communities, indirectly augment perceptions of corporate responsibility, and help firms to deflect controversies in an attentive global media environment. Despite these important roles, relatively little research has examined the institutional and strategic factors that influence such proximate charitable giving by firms. Using systematic data on foundations linked to S&P 3000 firms in the health sector – a growing domain in which public trust in high-stakes products and services is critical – fixed-effects models illustrate the primary role of network influences on giving: corporate foundations give substantially more in years following higher contributions by other (noncorporate) foundations in the health sector in a firm’s headquarters locality and also following increased contributions by industry peers through their corporate foundations. Giving also appears to reflect strategic reputational concerns, in that foundation contributions increase significantly following controversies associated with the corporate parent’s products and/or services. By contrast, giving tends to decline as the presence of outside directors on a firm’s board increases, as well as when firms carry heavier debt loads. Combined, these findings suggest that corporate foundations serve as a strategic proxy for the firm, reflecting both a company's position in community and interfirm networks while also mitigating the threat of reputational challenges.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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

Research limitations/implications

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.

Practical implications

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.

Originality/value

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