Despite the importance of layoffs in affecting individuals' socio-economic life chances, few sociological studies have been concerned with how this phenomenon is determined within the workplace. This study attempts to identify determinants of individual chances of layoff. Two diverse processes of layoff are investigated: one is"involuntary layoff", in which the employee offers to leave the organization; the second is"voluntary layoff", in which the employer decides whom is to be laid off. The probability of layoff is conceptualized as a function of both organizational properties and employee characteristics, and the two layoff processes are modeled as separate but related phenomena. The analysis is guided by hypotheses drawn from the economic and sociologicalliterature on quitting and layoff, and organizational literature on power, institutions and transaction costs. The data are from Brazilian public sector organization which was required by the government to lay off personnel in 1990. The results show that, first, voluntary layoff is a function of the higher utility of leaving compared to staying, given the job opportunities in the labor market. The results are similar to those found in studies of job quitting, but also show how organizational properties are important determinants of the decision to stay or leave. Second,concerning involuntary layoff, the main findings are: a)individual characteristics are a more relevant group of determinants of involuntary layoff thanorganizational properties; b)among the...

Os pomares de citrus das principais regiões do Estado de São Paulo vem sendo prejudicados pela cochonilha pardinha Selenaspidus sp. que suga a seiva das folhas e provoca a queda dos frutos. O uso indiscriminado de defensivos químicos vem contribuindo para a destruição dos inimigos naturais e consequente proliferação da praga. Com o objetivo de estudar a frequência ou a porcentagem de parasitismo dessa cochonilha, foram feitas coletas de folhas de laranjeira para valência de um pomar de 500 alqueires localizado em Brotas - SP, em 4 épocas diferentes dos anos de 1989/90. As folhas infestadas foram examinadas ao microscópio estetoscópio para contagem das carapaças com perfurações de saída dos parasitóides. Foram colocadas algumas folhas em placas de Petri para observacao da emergência dos parasitóides. As maiores porcentagens de parasitismo foram observadas nos meses de abril/90 (21,9%) e outubro/89 (21,4%) e a menor, (2,11%) em julho/89. Os parasitóides emergidos foram identificados preliminarmente por ROBBS como sendo Aphytis sp. |
