This document consists of four papers presented during a symposium on career development moderated by David Bjorkquist at the 1996 conference of the Academy of Human Resource Development (AHRD). "A Mentoring Model for Career Development" (Mary Finnegan) describes a study that created a model based on the assumption that mentoring is an essential tool for career development and beneficial to the organization, mentor, and protege. "Enhancing New Employee Development: A Longitudinal Examination of Socialization Processes and Turnover" (Elwood F. Holton, III, and Craig J. Russell) reports results that suggest aspects of newcomer preemployment anticipation, feedback seeking behavior, and adaptation difficulty predict voluntary turnover. "Developing the Portfolio Career" (Mary Mallon) considers a contemporary career transition from a successful position in an organizational hierarchy to the looser and more volatile world of building a career from a variety of working arrangements--a "portfolio career.""A Longitudinal Study of the Career Development and Aspirations of Women Managers in Business Firms (Second Phase)" (Rose Mary Wentling) analyzes interviews with 30 women managers who participated in the first phase 5 years ago. It reports the following findings: the majority had not attained the position to which they ultimately aspired; factors that assisted them in progressing were demonstrated competency, good interpersonal skills, perseverance, and company support; and barriers were being a woman, lack of opportunity, family obligations, and lack of boss's support. Papers contain references. (YLB)
