The necessity and utility of a hierarchical approach to model building in ecology is discussed. Some of the basic properties of hierarchies are described and criteria to discern subsystems are shown. A new approach of measuring the resilience in terms of natural probability of occurrence of a certain perturbation has been suggested, together with a stochastic definition of stability.

THE IMPORTANCE with which graduate training is regarded was shown by the fact that over 300 delegates attended the two‐day symposium held by the Institution of Mechanical Engineers on 22nd–23rd March. The representatives came from all interested fields — industry, the universities and technical colleges.

The purpose of this paper is to assess whether any meaningful lessons can be learned from South Africa's early twentieth century experience of White poverty and to what extent such lessons can be applied in order to combat Black poverty today.

This paper uses quantitative measures to assert the scale of poverty for both White and Black poverty in the two periods. An extensive discussion of the causes of poverty in both periods concludes with specific policy implications for today. Because of the unique characteristics and history of South Africa, this paper provides a unique dimension to poverty analysis.

The paper suggests that three key policy lessons can be learned from the twentieth‐century effort to combat White poverty and applied to Black poverty as it exists in South Africa today: an improvement in the quality of education, an improvement in the property right ownership of the poor, and policies to eliminate the constraints on economic growth, by investment, for example, in infrastructure and new technological industries.

Caution is advised when comparing past eras with the present; in comparing two periods that differ widely, only tentative recommendations is possible.

Since many areas of the world are faced with the difficult task of eradicating poverty, attempts that, to any extent, are successful are of interest and contribute positively to the development of the available knowledge base. The time‐span and design of this paper offers a unique perspective on poverty eradication efforts.

This chapter explores the implications of patrimonial politics in the Dutch East India Company empire in the context of establishing a settlement at the Cape of Good Hope in southern Africa in the mid-seventeenth century. The Cape extended the reach of Company patrimonial networks with elite Company officials circulating throughout the Indian Ocean empire and consolidating their familial ties through marriage both within the colonies and in the United Provinces. These patrimonial networks extended to the Cape as elite Company officials created families locally or married Cape-born women. As the colony grew, the Company created a class of free-burghers some the wealthiest of whom were tied directly into elite Company patrimonial networks. But from the early eighteenth century onwards these elite Company networks came into conflict with the evolving free-burgher patrimonial networks with which they were in direct competition. This paper argues that local patrimonial networks can evolve in a settler colony that challenge the elite patrimonial networks of the imperial elite.

To test this proposition a comparison was made between online and CD‐ROM costs in several heavily used databases. Among other factors considered were funding methods, staff investment, end‐user training, user access and cost recovery. The case of one South African academic library was examined in detail; the approaches of some other South African academic libraries were briefly touched on. Finally, although CD‐ROM was found to be more economic than online searching in the long term, the real problem would appear to be that South African academic libraries, in acquiring CD‐ROM, would be forced to choose, not between CD‐ROM and online, but between CD‐ROM and hard‐copy databases.

This study serves a dual purpose. First, it aims to explore the phase-wise progression that small and medium-sized enterprises (SMEs) and startups must undertake to become successful ecosystem partners, supporting large industrial firms in their circular transition. Second, it seeks to examine how these small firms manage change and foster collaborative cultures through strategies enabled by positive organizational scholarship (POS) during their phased evolution.

This study provides empirical evidence through a multiple case study-based approach involving 12 born-circular SMEs/startups from 5 diverse Indian industrial sectors. Insights were gathered by conducting two rounds of semi-structured interviews with 24 participants and one validatory seminar with eight participants.

This research identified three distinct and complementary phases – compare, compete and collaborate – that SMEs/startups can undergo to emerge as successful ecosystem partners. Each phase encompasses specific business practices, including various circular activities. These activities serve as clear indicators of the smaller firms’ potential competence in aiding larger firms during their circular transitions.

This paper contributes to the theoretical understanding of the circular economy by outlining a trajectory for SMEs/startups to establish successful partnerships. Another contribution is the application of POS as a positive change management paradigm to facilitate circularity. Additionally, the study highlights the context of developing nations, which remain underexplored compared to their developed counterparts in circularity initiatives.

Schooling in South Africa represents a history of gains and losses for sections of the society. The colonial, missionary, and apartheid political systems made schooling a weak instrument for mobility for the majority within society. Post-apartheid, although school reform has provided greater access to formal education, it continues to crystallize socioeconomic inequalities. A relatively small number of the previously disadvantaged receive education that facilitates economic and social mobility. The authors examine the new funding system and equity rhetoric that is employed to justify education access to different types of schools and argue that coupling the rhetoric of social transformation with the funding system for schools and thus class, continues the unequal historical education provision. School reform fails to compensate for the adverse effects of apartheid education and is largely reproductive rather than socially transformative. The conclusion is that unless South Africa overcomes the appeasing semantic trap in its policies, historical trends that make the constitutional ideal of equal rights unrealizable are likely to be entrenched.
