Identification of non-technical skills from the resilience engineering perspective: a case study of an electricity distributor

Training in non-technical skills (NTS) does not usually question the design of the work system, and thus focuses narrowly on workers as the unit of analysis. This study discusses how the identification of NTS, a major step for developing an NTS training program, might be re-interpreted from the perspective of resilience engineering (RE). This discussion is based on a case study of identifying NTS for electricians who perform emergency maintenance activities in an electricity distribution power line. The results of the case study point out that four data analysis procedures might operationalize the RE perspective: (a) identifying factors that make the work difficult and which could be integrated into NTS training scenarios; (b) identifying recommendations for re-designing the system, in order either to reduce or eliminate the need for NTS; (c) classifying the NTS into pragmatic categories, which are meaningful for workers; and (d) regarding the identification of NTS as an opportunity to give visibility to adaptations carried out by workers.     

Productivity,performance and project management in the scientific instrument industry

Scientific instruments have short product lifecycles and a lengthening of the time between design and application has serious financial implications. This paper reports on research aimed at obtaining a greater understanding of the factors which influence this interface. Interviews were conducted at 32 companies in two countries, the United Kingdom (UK) and the Federal Republic of Germany (FRG). The study showed that there are statistically significant differences between the two countries and that in the FRG there are also differences between projects led by people with different qualifications and background experience. These differences are analysed and discussed and factors identified which influence productivity and performance in the scientific instrument industry.     

Marriage, divorce, and legal change: new evidence from England and Wales

In this article, we explain the evolution of divorce rates in England and Wales over the post-war period. Following the approach of the predominantly North American literature in this area, we focus on the liberalization of divorce law and socioeconomic factors as determinants of the divorce rate. In line with the development of the literature, we find that the introduction of liberalized, no-fault divorce law had a significant effect on the divorce rate in England and Wales. The finding that the law affects the divorce rate is consistent with the view that marriage is characterized by indivisibilities that inhibit Coasian bargaining.     

Characterizing complexity in socio-technical systems: a case study of a SAMU Medical Regulation Center

Complexity theory has been adopted by a number of studies as a benchmark to investigate the performance of socio-technical systems, especially those that are characterized by relevant cognitive work. However, there is little guidance on how to assess, systematically, the extent to which a system is complex. The main objective of this study is to carry out a systematic analysis of a SAMU (Mobile Emergency Medical Service) Medical Regulation Center in Brazil, based on the core characteristics of complex systems presented by previous studies. The assessment was based on direct observations and nine interviews: three of them with regulator of emergencies medical doctor, three with radio operators and three with telephone attendants. The results indicated that, to a great extent, the core characteristics of complexity are magnified) due to basic shortcomings in the design of the work system. Thus, some recommendations are put forward with a view to reducing unnecessary complexity that hinders the performance of the socio-technical system.     

The effects of macroeconomic developments on individual companies' flows of funds

A system of models is described which traces the impact on individual companies' finances of changing the macroeconomic environment. This system comprises models of individual firms integrated with Cambridge's large-scale disaggregated model of the UK economy. Illustrative projections are provided for the period 1980–1988 for three companies under alternative exchange rate and interest rate assumptions; a balance sheet, income appropriation account and funds flow statement is generated for each company-year and each assumption. These case studies illustrate how sensitive companies' finances can be to changes in the macroeconomic environment and also how dissimilar can be the response of different companies' flows of funds to the same macroeconomic change.
