Understanding Midlife Career Renewal: Implications for Counseling

The thesis of this article is that sufficient and convincing research evidence has accumulated to indicate that a sixth stage of career development—career renewal—occurs for many people between the end of the establishment stage and the beginning of the maintenance stage. This article explains why a renewal stage was overlooked in the 1940s and 1950s, clarifies the meaning of renewal as it applies to career development, compares the transitions of men and women in their early 40s, and offers suggestions for the counseling of clients who are dealing with the task of career renewal.     

Benefit Analysis for Natural Hazards

The objective of this paper is to develop the ex ante perspective for benefit analysis with natural hazards. It defines an ex ante evaluation of the economic benefits that arise from policies designed to reduce either the risk of or the detrimental effects associated with a natural hazard. In the process the paper compares the ex ante and ex post perspectives and discusses the prospects for implementing the framework by measuring the valuation concepts that are developed.     

Estimation of parameters in survey sampling: Optimality

Some recent works on estimation in survey sampling are analyzed and extended from the perspective of the theory of optimal estimating functions.     

The Relationship between Economic Development and Social Welfare: A New Adjusted GDP Measure of Welfare

Existing literature focuses on the issue ofpreparation of social welfare measurements onthe basis of an unadjusted Gross DomesticProduct (GDP). This paper extends this methodto incorporate cost-benefit analysis ofeconomic growth in a growing economy incalculating the adjusted GDP, termed as thecost-benefit (CB)-adjusted GDP. This approachis empirically applied to Thailand. There arestark differences between GDP per capita and CBadjusted GDP per capita rates for this period.This paper concludes that GDP can be used as anindicator of social welfare if the GDPestimates are undertaken within a cost-benefitanalysis framework.     

Statistical approaches for the reliability of structural designs

The Construction Industry Research and Information Association (CIRIA) has produced some guidelines for the assessment of the reliability of components and/or structures. The methods of analysis suggested by these guidelines are far from adequate and, in certain cases, contain some imperfections. In this paper, some of the weaknesses of the guidelines are identified. The shortcomings are mainly in the ease of calculations and the feasibility of the assumptions which are imposed. Three alternative methods aimed at tackling some of the weaknesses are introduced. A simulation study is used to compare these methods.     

Modelling age variation in survival and reporting rates for recovery models

In this paper, we focus on models for recovery data from birds ringed as young. In some cases, it is important to be able to include in these models a degree of age variation in the reporting probability. For certain models this has been found, empirically, to result in completely flat likelihood surfaces, due to parameter redundancy. These models cannot then be fitted to the data, to produce unique parameter estimates. However, empirical evidence also exists that other models with such age variation can be fitted to data by maximum likelihood. Using the approach of Catchpole and Morgan (1996b), we can now identify which models in this area are parameter-redundant, and which are not. Models which are not parameter-redundant may still perform poorly in practice, and this is investigated through examples, involving both real and simulated data. The Akaike Information Criterion is found to select inappropriate models in a number of instances. The paper ends with guidelines for fitting models to data from birds ringed as young, when age dependence is expected in the reporting probability.     

A comparative study on detection of influential observations in linear regression

A large number of statistics are used in the literature to detect outliers and influential observations in the linear regression model. In this paper comparison studies have been made for determining a statistic which performs better than the other. This includes: (i) a detailed simulation study, and (ii) analyses of several data sets studied by different authors. Different choices of the design matrix of regression model are considered. Design A studies the performance of the various statistics for detecting the scale shift type outliers, and designs B and C provide information on the performance of the statistics for identifying the influential observations. We have used cutoff points using the exact distributions and Bonferroni's inequality for each statistic. The results show that the studentized residual which is used for detection of mean shift outliers is appropriate for detection of scale shift outliers also, and the Welsch's statistic and the Cook's distance are appropriate for detection of influential observations.     

New patterns of delivering service in British Columbia.

A new approach to social services, including services to children, is being taken by the government of the New Democratic Party that assumed office in British Columbia in 1972.
