C square-wave pulse inverter controlled by DSP was introduced. TMS320-serial DSP produced by Texas Instruments Corp., its developing environment and program flow, and the use of the software CCS were also introduced. According to the requirement of output waveform, the main program of control system, interruption service routine, and subroutines were designed by using modularized software design method.

‘A Pioneer in the Struggle for Social Justice’: Manuel Larraín and Transnational Catholic Activism in Latin America in the 1950s and 1960s

This article explores the development of inter-American Catholicism during the 1950s and 1960s. It analyses the role of the Chilean Catholic bishop Manuel Larraín (1900–1966) in his efforts to disseminate his diagnosis of underdevelopment in Latin America and to establish links with the Catholic world in the United States. Based on a review of his writings, the American press and documentation from Catholic organisations, it is suggested that the Chilean bishop advocated the implementation of social reforms and American collaboration to prevent the advance of communism and strengthen Catholicism on the continent.     

Strategies and hybrid dynamics of soy transnational companies in the Southern Cone

Economical liberalization, market globalization and soy expansion stimulated the advance of big transnational companies in the Southern Cone countries (Brazil, Argentina, Paraguay and Uruguay). Currently, the main corporations acting on the last links of the productive chain are ADM (Archer Daniels Midland), Bunge, Cargill and Dreyfus (the ABCD firms), global leaders in the soy trade. The objective of this contribution is to analyze the different strategies these companies articulate in the Southern Cone, and their dynamics in local space through market relations with local producers. The results show the rapid and intense process of denationalization of the firms in the soy productive chain as well as the high level of market internationalization and company concentration. In spite of this, this study shows that all transnational power of ABCD firms, which seems so abstract and intimidating when seen in the global scale, depends on its basis of the formation, maintenance and exploration of relations of proximity, trust and reciprocity with local actors (especially rural producers), including family friendship linkages.     

Psychologists as ‘the quiet ones with the power’: understanding indeterminate sentenced prisoners’ experiences of psychological risk assessment in the United Kingdom

ABSTRACT

Prisoners serving indeterminate sentences in the United Kingdom do not know when or if they will be released from prison. Release and progression decisions are determined by the risk the ISP presents of reoffending. This makes the assessment of risk a high stakes business for ISPs. Whilst there is a large body of literature focused on prisoners’ general experiences of prison, there is an absence of specific empirical exploration of prisoners’ experiences of risk assessment. This paper aims to address this gap by reporting the results of a qualitative exploration of ISPs’ experiences of psychological risk assessment. Interviews with 10 ISPs were conducted and analysed using Grounded Theory methods. Analysis indicated that prisoners experienced the prison environment as characterised by violence, volatility and suffering. Psychological risk assessment is embedded within this emotionally and physically challenging context but also contributes to the experience of suffering. Within this context, prisoners felt stuck, powerless and out of control in relation to risk assessment, and experienced psychologists as untrustworthy yet powerful. Understanding prisoners’ experiences is the first step in resolving some of the long-reported difficulties in working relationships between psychologists and prisoners as well as making the process more procedurally just.
