Commerce,class and ethnicity: Cape Town at the advent of the mineral revolution (c.1875)

This paper is about economic activity, social structure and ethnicity in the Cape Town of the 1870s. In an attempt to combine quantative methodology with insight gained from written records, I have made extensive use of the Census of1875. Cape Town in that year displayed many similarities with Stedman Jones’ Outcast London. In both cities economic power lay with “those whose income derived from rent, banking and commerce.” Seasonality of production, types of casual occupations and a strong artisanal sector characterised both labour markets. Units of production were small. There was in both cities a notable absence of one of Marx and Engels’ fundamental classes, the industrial proletariat. Instead, amongst a sea of casual labour there was the strong presence of the self‐employed resisters of proletarianisation. I have attempted to show how the white ethnicity of dominant class consciousness both conformed to, and confirmed, class position. This white ethnicity differed from white racism in that it did not condemn people it defined as “Other than White” to perpetual inferiority or cultural difference. The nature of economic activity in the city, together with the reality of both white and coloured? Capetonians in almost all gradations of the under classes, made a rigidly ethnically ordered society or ethnically hierarchical division of labour unlikely.     

ERP implementation: An integrated process of radical change and continuous learning

This paper seeks to develop management theory that can be used to increase the likelihood of ERP implementation success. The paper argues and demonstrates that an ERP implementation can be understood as an intended radical change that can be managed to some extent. But during the use of the system, incremental changes are bound to take place, which are unintended and difficult to manage. Using, therefore, and combining positivist and constructivist viewpoints, six different propositions on ERP implementation are developed. The paper reasons that organizations that understand these propositions are more likely to implement and use ERP successfully. The findings of a longitudinal case study of the implementation and use of BaaN in a Danish company support the propositions put forward in the paper.     

The State of the Social Work Profession: A Systematic Review of the Literature on Antigay Bias

Antigay bias delimits the rights of sexual minorities. Given that the social work profession promotes social justice values, understanding the extent to which antigay bias exists within the profession is important. Two social work specific populations were included in this systematic literature review to capture the breadth of the profession: professionals and students. A total of 31 empirical articles met our inclusion criteria. Across the samples, social workers and students were found to have mostly positive attitudes toward gays and lesbians. The sociodemographic factors used to explain the variance in attitudes are reported, and suggestions for future research are provided.     

Telling it like it was. Audio-taping stories told by mental health service users and carers

This paper begins by claiming that the telling and hearing of stories is intrinsic to the social work task. Examples of the value of hearing stories in a variety of social work roles are provided, as are examples of the theoretical underpinnings which substantiate the importance of enabling service users and carers to tell their stories. The main focus of the paper is on relating how audio-taping the experiences of service users and carers evolved as part of the author's work. With the permission of those interviewed, examples are quoted from accounts of three different family members attempting to deal with a relative's progressive deterioration into severe dementia. These accounts are followed by the memories of a woman who took an overdose and was subsequently ‘ectioned’ under The Mental Health Act 1983. An interview with two parents attempting to respond to the needs of their schizophrenic son is discussed. Some of the unexpected positive repercussions of recording interviews with these service users are described and some cautions are also highlighted. The paper concludes with suggestions of how audio-taping the stories of service users can be used to benefit social workers engaged in various aspects of social work today.     

On-shift and daily variations in self-report and performance measures in rotating-shift and permanent night nurses

Abstract

An intensive study was conducted of the influence of type of shift system, type of shift, and time-into-shift on a battery of on-shift and daily measures obtained from 61 female nurses over a 28-day period. Thirty-two rotating-shift nurses and 28 permanent night nurses recorded data on a hand-held computer at the start and end of each day, and every 2-h during their shifts. The measures included a sleep diary, self-ratings of mood, workload, and personal disruption, and two cognitive performance tasks. These results suggest that the permanent night nurses were no worse off and for some measures were actually better off than the rotating-shift nurses after controlling for differences in age and shiftwork experience; the night-shift was problematic for the rotating-shift nurses but so was the early shift; mood deteriorated and reaction time got slower over the course of the night-shift but extra long responses (which may correspond to lapses of attention) and rated workload were lower on the night-shift. The relatively large number of consecutive night-shifts worked by the rotating-shift nurses, the uneven distribution of workload between shifts, and the long night-shift may have contributed to these results.

Group work is … powerful! This stuff changes … lives: training on group processes for facilitators of curriculum-based groups

ABSTRACT

This article describes a four-year group work training project conducted with facilitators of curriculum-based parenting groups who had not been trained in group work or group processes. A total 14 group facilitators and 144 group members from 34 groups were involved in the training and the mixed method evaluation. Participants described how the training modified their group facilitation, helping them understand that the groups themselves as well as the curricula were informative and transformative, and that group members as well as group facilitators had roles. Further, facilitators indicated that the training resulted in fundamental change in their self-perceptions from being simply purveyors of a parenting curriculum to empathic agents of change as well.     

Interdependent Network Recovery Games

Recovery of interdependent infrastructure networks in the presence of catastrophic failure is crucial to the economy and welfare of society. Recently, centralized methods have been developed to address optimal resource allocation in postdisaster recovery scenarios of interdependent infrastructure systems that minimize total cost. In real-world systems, however, multiple independent, possibly noncooperative, utility network controllers are responsible for making recovery decisions, resulting in suboptimal decentralized processes. With the goal of minimizing recovery cost, a best-case decentralized model allows controllers to develop a full recovery plan and negotiate until all parties are satisfied (an equilibrium is reached). Such a model is computationally intensive for planning and negotiating, and time is a crucial resource in postdisaster recovery scenarios. Furthermore, in this work, we prove this best-case decentralized negotiation process could continue indefinitely under certain conditions. Accounting for network controllers' urgency in repairing their system, we propose an ad hoc sequential game-theoretic model of interdependent infrastructure network recovery represented as a discrete time noncooperative game between network controllers that is guaranteed to converge to an equilibrium. We further reduce the computation time needed to find a solution by applying a best-response heuristic and prove bounds on ε-Nash equilibrium, where ε depends on problem inputs. We compare best-case and ad hoc models on an empirical interdependent infrastructure network in the presence of simulated earthquakes to demonstrate the extent of the tradeoff between optimality and computational efficiency. Our method provides a foundation for modeling sociotechnical systems in a way that mirrors restoration processes in practice.     

Simultaneous Search

We introduce and solve a new class of “downward‐recursive” static portfolio choice problems. An individual simultaneously chooses among ranked stochastic options, and each choice is costly. In the motivational application, just one may be exercised from those that succeed. This often emerges in practice, such as when a student applies to many colleges or when a firm simultaneously tries several technologies. We show that such portfolio choice problems quite generally entail maximizing a submodular function of finite sets—which is NP‐hard in general. Still, we show that a greedy algorithm finds the optimal set, finding first the best singleton, then the best single addition to it, and so on. We show that the optimal choices are “less aggressive” than the sequentially optimal ones, but “more aggressive” than the best singletons. Also, the optimal set in general contains gaps. We provide some comparative statics results on the chosen set.
