Abstract

Purpose

The desired retirement age (DRA) becomes more important because some countries adapt their strict retirement regulations to it. A process is tested for how psychological empowerment influences the DRA mediated by psychological and physical strain and how the DRA is connected to the expected retirement age (ERA). The paper aims to discuss these issues.

Design/methodology/approach

Structured interviews with 1,485 German employees (55 years and older) were conducted via telephone.

Findings

Psychological and physical strain mediated both the relationship between psychological empowerment and the DRA. DRA and ERA were positively associated. The control variables – age, net income, and organizational size – also significantly affected the DRA.

Research limitations/implications

The results are only valid for the German job market. All variables were collected at one measurement point.

Practical implications

The strengthening of psychological empowerment can be one measure to motivate older employees to delay their retirement and finally keep them longer in the labor force.

Originality/value

A large sample was collected and interviewed via telephone, which helps to overcome some limitations of questionnaire research. The process model helps to understand how job characteristics are connected with the DRA and the ERA.

Abstract

This article is supplied by Alison, a long‐time member of Dual Recovery Anonymous (DRA), about the aims and principles of their 12‐step programme. DRA's 12‐step programme helps members to recover from both a drug or alcohol dependency and emotional or psychiatric illness (dual diagnosis) by focusing on relapse prevention and actively improving the quality of their lives.

Abstract

Purpose

This paper aims to traitted the combined effects of ferromagnetic particles and magnetic field on mixed convection in the Falkner Skan equation using analytical solution by the Duan–Rach method.

Design/methodology/approach

Visualization and grouping of effects of various physical parameters such as electrical conductivity of ferro-particles (electrical conductivity calculated using Maxwell model), ferro fluid volume fraction for Magnetite-Fe3O4-water and magnetic field represented by the Hartmann number in a set of third- and second-order nonlinear coupled ordinary differential equations. This set of equations is analytically processed using the Duan–Rach Approach (DRA).

Findings

Obtained DRA results are validated using a numerical solution (Runge–Kutta–Fehlberg-based shooting method). The main objective of this research is to analyze the influence of physical parameters, in particular electrical conductivity, Ferrofluid volume fraction in the case of Magnetite-Fe3O4-water, in addition to the types of solid nanoparticles and Hartmann number on dynamic and thermal distributions (velocity/temperature). Results of the comparison between the numerical solution (Runge–Kutta–Fehlberg-based shooting method) and the analytical solution (DRA) show that the DRA data are in good agreement with numerical data and available literature.

Originality/value

The study uses Runge–Kutta–Fehlberg-based shooting method) and the analytical solution (DRA) to investigate the effect of mixed convection, in the presence of Ferro particles (Magnetite-Fe3O4) in a basic fluid (water for example) and subjected to an external magnetic field on the Falkner–Skan system.

Abstract

Gives an in depth view of the strategies pursued by the world’s leading chief executive officers in an attempt to provide guidance to new chief executives of today. Considers the marketing strategies employed, together with the organizational structures used and looks at the universal concepts that can be applied to any product. Uses anecdotal evidence to formulate a number of theories which can be used to compare your company with the best in the world. Presents initial survival strategies and then looks at ways companies can broaden their boundaries through manipulation and choice. Covers a huge variety of case studies and examples together with a substantial question and answer section.

Abstract

Flying has long been considered a safe means of travel, although 100 per cent safety can never be guaranteed. The Defence Research Agency's (DRA's) Spectrometric Oils Analysis Programme, SOAP, helps to ensure aircraft stay fault‐free for as long as possible by providing an accurate, rapid spectrometric service, analysing wear metals in engine and gear‐box lubricants. The DRA enables the RAF to make significant improvements in safety, through optimizing machine uptime and decreasing routine maintenance. Annual savings of several million pounds in service and failure costs are also achieved.

Abstract

In December 1988, the Los Angeles County Public Library entered into an agreement with the Security Pacific Merchant Bank of Los Angeles for the five‐year lease/purchase of a $5.3 million Automated Circulation System (ACS) from Data Research Associates (DRA) of St. Louis. The previous June, the Public Library had entered into a cash contract with DRA, but shifted its position after determining that it was to the County's advantage to lease/purchase the system rather than using available cash fund balances needed for other budgetary priorities. The June 1988 contract with DRA included a clause allowing the assignment of ownership for financing purposes. After negotiating the best possible agreement to purchase the computer system, the County, on behalf of the library, leased/purchased the system from the bank which in turn issued Certificates of Participation to raise the cash from persons and corporations who wanted to purchase relatively short term income tax free investments.

Abstract

In September 1990, the U.S. Department of Education's Library Technology and Cooperation Grants Program awarded a three‐year grant to the Florida Center for Library Automation (FCLA), an agency of the Florida State University System, to develop software adhering to the ANSI Z39.50 Information Retrieval protocol standard. The Z39.50 software was to operate over the Open Systems Interconnect (OSI) communications protocols and be integrated with FCLA's NOTIS system, which is shared by all nine state universities in Florida. In order to test the correctness of its Z39.50 software, FCLA sought out other library software developers who would be willing to develop Z39.50 systems of their own. As part of this process, FCLA helped to found the Z39.50 Implementors' Group (ZIG), which has since gone on to improve the standard and promote Z39.50 implementations throughout much of the North American library systems marketplace. Early on in the project, it became apparent that TCP/IP would be a more heavily used communications vehicle for Z39.50 messages than OSI. FCLA expanded its design to include TCP/IP and, by the end of the grant in September 1993, will have a working Z39.50 system that can communicate over both OSI and TCP/IP networks.

Abstract

The verbal protocol method is used extensively in computer usability studies. This study was designed to test the feasibility of using the verbal protocol method as a means of conducting field research on the online catalogue. Ten undergraduate students conducted their own research on DRA’s Infogate. As they searched, they talked aloud about what keys they were pressing, what was happening on the screen, and their reactions. Transcripts of sessions were analyzed. A total of 65 different problems or comments were noted during search sessions, with 11 problems or comments noted in three or more sessions. This supports the hypothesis that the verbal protocol method is a valuable means of identifying common problems for users. It is suggested that the verbal protocol method offers great potential as a research tool in librarianship, for example in the area of interface design.
