A Meta-Analytic Study of Downsizing: Behaviors and Attitudes Prevalent Among Supervisors

Current research into the effect of downsizing, restructuring, and force reduction on employees has approached the issue many possible vantage points it has focused on the victims, the survivors, and sometimes both. Researchers in management science and psychology explain responses we can expect from survivors of such a corporate upheaval. These effects are of particular interest to supervisors, because they will inevitably face a workforce, at least partially staffed with such survivors. To clarify possible attitudes and behaviors in tomorrow’s work environment, our study tied together, through meta- analysis, results of studies on survivors of a downsized organization. The completed analysis enables managers to preview in the aggregate sense a certain set of downsizing survivor responses. A questionnaire was used to gather added data on survivor’s reactions to and feelings about their organization. The results were incorporated into the meta-analysis statistics, and credibility intervals established. This interval will serve to identify the true population correlations for the variable relationships presented in the current research literature

Induction of sterility in Anastrepha fraterculus (Diptera: Tephritidae) by gamma radiation

In relation to the application of the sterile insect technique (SIT) for the South American fruit fly Anastrepha fraterculus (Wiedemann), we analyzed the effect on adult fertility of different doses of gamma irradiation and the age of pupae at the time of irradiation. In a first experiment, we applied doses of 50, 70, and 90 Gy to pupae at 24, 48, 72, and 96 h before adult emergence. In a second experiment we irradiated pupae 48 h before emergence with 20, 40, and 60 Gy and estimated male and female fertility and sperm transfer by irradiated males. The results indicated pupal age at irradiation does not significantly affect male fertility. If males irradiated with 60 Gy are crossed to non-irradiated females the fertility is about 1%. Females irradiated with 40 Gy did not lay eggs independently of the male to which they mated. No significant effects of radiation were observed with respect to the ability of males to transfer sperm. A dose of 70 Gy applied 48 h before adult emergence induces 100% sterility in both males and females.Fil:Vilardi, J. Universidad de Buenos Aires. Facultad de Ciencias Exactas y Naturales; Argentina
