The rhetorical construction of efficiency: Restructuring and industrial democracy in Mondragón,Spain

This paper examines the tension between the struggle to survive in a competitive economy and efforts to create more democratic workplaces in the Basque worker cooperative complex in Mondragón, Spain. Data from archival research, participant observation, and interviews are used to outline the historical context of structural change and policy-making in the complex. Language used in internal policy discussions is analyzed to explore the way in which arguments about efficiency have shaped interpretations of structural change and these organizations' policy responses. It is argued that in these cooperatives, the concept of efficiency does not operate as a neutral, objective benchmark of organizational performance, but is socially and rhetorically constructed. The predominant approach to efficiency that is emerging in Mondragón aims to make the cooperatives more competitive, but also facilitates a gradual displacement of collectively established organizational objectives such as relative equality, job security, and favorable work conditions for ones that privilege institutional interests of profitability and stability. More importantly, it has helped usher in important changes in the policy-making process itself, limiting the range of legitimate participation and weakening broad-based control over the identification of appropriate objectives and means. The paper suggests that reframing an existing rhetorical strategy to highlight more clearly the link between efficiency and any given set of objectives would stimulate a broader discussion of policy issues and help balance more effectively the diverse interests at stake in Mondragón's restructuring.An earlier version of this paper was presented at the 1992 annual meetings of the American Sociological Association in Pittsburgh, Pennsylvania.     

Extending pension coverage in Cambodia: The governance and investment challenges of the Social Security Investment Fund

Rapid economic growth, declining fertility and changes in family structures have encouraged the Kingdom of Cambodia to reform its old-age pension system. The Government of Cambodia reached an important milestone in 2019, when the Law on Social Security was promulgated. The Law includes provisions for a compulsory defined benefit pension scheme, establishing a sound framework for extending compulsory pension coverage beyond the public sector to formal private-sector workers. As a future step, the compulsory pension scheme should be extended to informal workers. To accompany the reform, the investment policy for the pension scheme’s reserve funds, including the supervisory regime and investment strategy, will be essential for the modernization of the Cambodian social security system. In this regard, Cambodia has successfully sought policy advice. However, the country should continue to seek further advice, and to act on this. Otherwise, the necessary and increasingly pressing policy ambitions of Cambodia to develop an adequate and sustainable social protection system may not be fully realized.     

Expanding social health protection in Cambodia: An assessment of the current coverage potential and gaps,and social equity considerations

The Royal Government of Cambodia recently launched its National Social Protection Policy framework to strengthen and expand social security and assistance. To inform social health protection policy, we examine socio-economic survey data and administrative coverage data to assess the coverage potential of existing coverage mechanisms and current gaps; and compare equitable contribution rates. Over 53 per cent of the population currently has no social health protection coverage mechanism, and about 16 per cent of the population who do have access to a mechanism are not yet enrolled. Current expansion efforts focus on the formal employee scheme, primarily benefiting individuals from higher income households. In addition, recent coverage expansion to some informal workers leaves significant gaps, particularly among the informal sector. We find out-of-pocket health care expenditure to be an excessive share of income among lower wealth quintile individuals and conclude they are financially vulnerable. Finally, we illustrate that an equitable approach to individual, monthly health care contributions among the lower three quintiles has a severely limited potential for revenue generation, and collection costs could exceed the amount collected. Therefore, we recommend that vulnerable groups should be exempted from contribution payments as social health protection is expanded.     

Employer‐oriented labour market policies in Sweden: Creating jobs and the division of labour in the public sector

In many European countries, greater importance is accorded to labour market policies in which employers are involved in activating unemployed people. Such employer‐oriented policies target employers’ demand for labour and attempt to influence their willingness to hire, train or guide (often disadvantaged) unemployed groups. Using data from a qualitative interview study of an employer‐oriented programme in a medium‐size city in Sweden, the present article aims to develop knowledge about how these policies are used to influence employers to hire unemployed workers and how jobs created in this context differ from regular jobs. The article argues that creating jobs through new arrangements for the division of labour, with the promise of relieving regular staff of unskilled tasks, may influence employers’ willingness to hire the unemployed when used alongside other kinds of policy instruments. However, the article also shows that this new division of labour, with programme participants performing mainly unskilled tasks, has been difficult to realize, as new staff gradually come to perform an increasing number of regular working tasks.     

Stimulus equivalence, generalization, and contextual stimulus control in verbal classes

Stimulus generalization and contextual control affect the development of equivalence classes. Experiment 1 demonstrated primary stimulus generalization from the members of trained equivalence classes. Adults were taught to match six spoken Icelandic nouns and corresponding printed words and pictures to one another in computerized three-choice matching-to-sample tasks. Tests confirmed that six equivalence classes had formed. Without further training, plural forms of the stimuli were presented in tests for all matching performances. All participants demonstrated virtually errorless performances. In Experiment 2, classifications of the nouns used in Experiment 1 were brought under contextual control. Three nouns were feminine and three were masculine. The match-to-sample training taught participants to select a comparison of the same number as the sample (i.e., singular or plural) in the presence of contextual stimulus A regardless of noun gender. Concurrently, in the presence of contextual stimulus B, participants were taught to select a comparison of the same gender as the sample (i.e., feminine or masculine), regardless of number. Generalization was assessed using a card-sorting test. All participants eventually sorted the cards correctly into gender and number stimulus classes. When printed words used in training were replaced by their picture equivalents, participants demonstrated almost errorless performances.     

Effects of differential reinforcement and rules with feedback on preference for choice and verbal reports

We evaluated the effects of differential reinforcement and accurate verbal rules with feedback on the preference for choice and the verbal reports of 6 adults. Participants earned points on a probabilistic schedule by completing the terminal links of a concurrent-chains arrangement in a computer-based game of chance. In free-choice terminal links, participants selected 3 numbers from an 8-number array; in restricted-choice terminal links participants selected the order of 3 numbers preselected by a computer program. A pop-up box then informed the participants if the numbers they selected or ordered matched or did not match numbers generated by the computer but not displayed; matching in a trial resulted in one point earned. In baseline sessions, schedules of reinforcement were equal across free- and restricted-choice arrangements and a running tally of points earned was shown each trial. The effects of differentially reinforcing restricted-choice selections were evaluated using a reversal design. For 4 participants, the effects of providing a running tally of points won by arrangement and verbal rules regarding the schedule of reinforcement were also evaluated using a nonconcurrent multiple-baseline-across-participants design. Results varied across participants but generally demonstrated that (a) preference for choice corresponded more closely to verbal reports of the odds of winning than to reinforcement schedules, (b) rules and feedback were correlated with more accurate verbal reports, and (c) preference for choice corresponded more highly to the relative number of reinforcements obtained across free- and restricted-choice arrangements in a session than to the obtained probability of reinforcement or to verbal reports of the odds of winning.     

General Outcome Measures for Verbal Operants

A general outcome measure (GOM) can be used to show progress towards a long-term goal. GOMs should sample domains of behavior across ages, be sensitive to change over time, be inexpensive and easy to use, and facilitate decision making. Skinner''s (1957) analysis of verbal behavior may benefit from the development of GOM. To develop GOM, we conducted a review of the literature on mands, tacts, echoics, and intraverbals. The four areas reviewed included (a) an examination of the participant''s response form (i.e., vocal or nonvocal), (b) the type of prompt used, (c) types of materials used, and (d) timing of responses or sessions. Based on the review of the literature, we developed GOM for mands and tacts. This paper attempts to bridge the concept of GOMs with Skinner''s analysis of verbal behavior.     

“We have to take these guys out”: Motivations for Assaulting Incarcerated Child Molesters

We know very little about how incarcerated men justify assaults against at‐risk inmates such as child molesters. For this article, we fill this gap in the literature by examining how men describe these assaults as a way to align their own violent behavior with more conventional mores. We find that formerly incarcerated men justify violence as a way to raise their own social status and promote cultural norms against child abuse. When inmates attack someone convicted of child molestation, they do so to punish him and provide a “service” to their community. Furthermore, they elevate their own social status and distance themselves from these offenders. Theoretically, this work broadens our understanding of verbal justifications for violent action.
