The reliability of thick film multilayer systems, based on palladium‐silver conductors, and obtained from several suppliers, is evaluated. A test structure is presented and the impact of different parameters, such as humidity, temperature, voltage bias and presence of overglaze, on the data is discussed. A SEM analysis of the failed samples allows identification of the failure mechanisms as due to flaws (pinholes and inclusions) in the dielectric.

Among developing countries, the Republic of China in Taiwan (hereinafter Taiwan) has been experiencing economic growth accompanied by improving income distribution. Between 1964 and 1980, the average annual growth rate of the real gross national product was 9.92 per cent (Council for Economic Planning and Development (CEPD), 1982, p. 23). In the same period, the income ratio between the top 20 per cent and the bottom 20 per cent of families dropped from 5.33 to 4.17 and the Gini coefficient decreased from 0.36 to 0.30 (CEPD, 1982, p. 54; Directorate‐General of Budget Accounting and Statistics, 1980, (DGBAS), p. 44). To put it somewhat dif‐ferently, in 1964 the lowest fifth of households received 7.71 per cent of total personal income, and the highest fifth 41.07 per cent. But in 1980, the income share of the lowest fifth increased to 8.82 per cent while that of the highest fifth decreased to 36.80 per cent. The condition of greater equality in income distribution appears more obvious in the capital city of Taipei. In 1981, for instance, its Gini coefficient was estimated to be only 0.28 (Taipei Bureau of Budget, Accounting and Statistics, 1981, (TBBAS), P. 24).

Schmoller reserves his admiration for those entrepreneurs who succeeded in the acquisition of wealth but whose primary goal was the promotion of the public interest. Such individuals as List, Steiner, Geibel, Abbe and von Mevissen are of this sort. Schmoller is lavish in his praise of them. Schmoller is critical of the natural economy of Adam Smith where each individual is activated by his own self‐interest. Schmoller sees in the higher law a guide to human behaviour. Moneymakers are not necessarily men of great talent. For this reason Schmoller prefers the man who is driven by the pursuit of idealistic goals. Schmoller′s historical approach to the political economy, one shared by some in the Western world, is to be contrasted with the view that the best type of social order permits the individual to pursue his self‐interest and that such a pursuit is in keeping with the social interest.

This chapter provides an understanding of the state of social protection mechanisms in the Southern African Development Community region and gives reference to two cases from the same region in relation to their social protection response during the COVID-19 pandemic. Secondary data were used to provide an understanding of social responsive measures to mitigate poverty during the COVID-19 pandemic in the region. Existing literature, policies and programmes relative to the social measures to mitigate poverty during the COVID-19 in South Africa and Zimbabwe were reviewed. The study highlighted the importance of preparedness of governments to respond to shocks in order to provide social protection to citizens. It further highlighted the need to adopt more sustainable strategies to help mitigate the effects of pandemics and the need to cushion citizens from the socio-economic effect of future pandemics.

A study conducted by UN Habitat (2020) revealed that financing of investment in African growing cities has become an impediment amid the COVID-19 pandemic. Close to USD 93 billion is needed to finance urban development in Africa. The prevalence of COVID-19 pandemic impacted negatively on the independence of African cities to raise revenue or incur long-term debt to finance their development. Several local governments in African cities are not positioned enough to ensure quality standards of living for their people. This is because many local authorities in African cities cannot intervene in various emergencies or crises which pose a danger to people given the COVID-19 pandemic era where strategic government interventions are essential to save the lives of the people. Burdened by the need to respond to COVID-19, many African governments have diverted their attention from the smart city ideology which demands stable financial revenues and redirected their efforts towards mitigating the scourge of the pandemic. Drawing from this background, therefore this chapter reports on the three selected African cities (Johannesburg, Lagos and Accra) because of their experiences regarding COVID-19, and their responses to the pandemic towards achieving a smart city in Africa. The chapter is guided by the following specific objectives: To examine the unintended consequences of COVID-19 on the achievement of Smart Cities in three African Cities; to assess the opportunities and challenges of achieving smart cities amid COVID 19 in three African Cities; and to determine how rapid urbanisation affects the achievement of Smart Cities amid COVID-19 in three African Cities. Qualitative thematic analysis was used to analyse data acquired from secondary sources.

This paper aims to explore the responses of households in the informal economic sector to the Cameroon Government strategy against Covid-19 in Yaounde, Cameroon between March and May 2020.

Given the recency of Covid-19, the exploratory design was used to collect and analyse information for the study. Empirical data was obtained through personal observations and questionnaires, whereas grey data were sourced from official sources in government and international agencies in Yaounde. The mode of the ordinal data generated from the questionnaire was used to characterise the attitudes of respondents to quarantine measures and bar charts were used to illustrate the distribution of responses.

The government’s strategy against Covid-19 was largely ignored in Yaounde between March and May 2020 because of the influence of the predominantly informal economy on household’s ability to allocate scarce resources between the competing needs of protecting their health on the one hand, and their livelihoods on the other hand. Poor households had to walk a difficult line between shutting down their businesses to protect their health or risking Covid-19 infections to protect their livelihoods. Over 53.1% of respondents thought quarantine measures were unsuccessful as over 63% ignored them. Quarantining and Social distancing were also difficult in informal settlements because of structural congestion.

Perhaps, the greatest limitation of this study was the use of non-probability sampling. As such, sampling error could not be estimated, blurring the ability to ascertain the degree of similarity between the sample and the study population. This made sample generalisability difficult.

There are short-term and long-term policy implications of these findings. Basic comprehensive measures including food and water distribution, as well as rent holidays, must be implemented in informal neighbourhoods to ensure more successful quarantines in future pandemics. In the long run, investments in urban social housing must be carried out to reduce slums, an ever-present risk factor in the rapid propagation of infections.

The originality of this study is first, in its level of analysis which is the household. By measuring household responses to quarantine measures within defined neighbourhoods, the study deviates from most that have adopted a theoretical approach and conducted analysis at country or regional levels. Few studies have attempted to investigate the failure of quarantine measures against Covid-19 from the viewpoint of the occupational characteristics of the populations involved.

The purpose of this paper is to summarize the main findings and conclusions of four separate studies on treatment in therapeutic communities (TCs) for addictions.

The first two studies address the core characteristics of the TC approach: a study on the workable and destructive elements of the Synanon model; and a comparative study on the essential elements of TCs for addictions in Europe and in the USA. The final two studies highlight clients’ perceptions of the TC treatment process in relation to retention: a study on clients’ first month perceptions of the TC treatment process and the influence of fixed and dynamic client factors; and a longitudinal study on changes in clients’ perception of the TC treatment process and the impact of motivation, psychological distress and cluster B personality traits.

The first study showed that Synanon’s therapeutic and pedagogical methods are still highly valued despite its negative reputation. The results of the second study suggest that while traditional TCs operate as concept-based TCs in Europe, modified TCs might differ in the extent to which they apply the core principles and elements of the TC approach. The third study provides evidence that suitability for treatment is a very important predictor for clients’ first month perceptions of the community environment. The fourth study shows that with time in treatment clients develop more profound perceptions regarding the essence of TC treatment.

Finally, implications for clinical practice, general limitations and some concrete recommendations for future research are presented in this paper.

The PhD summary study contributes to the existing literature on TC treatment.

With rising public concern over animal welfare, food safety and GM crops, Europe’s farmers, breeders and food processors are caught in the eye of a storm. While some are “returning to the soil” with traditional organic methods, others are breeding crops and animals using biotechnology, for markets as diverse as power generation and pharmaceuticals. For Europe’s policymakers social and ecological sustainability are paramount, but public information is also a prerequisite for meaningful debate.

Most contemporary economists feel ill at ease with respect to big topics — national economic organisation, interpretation of economic history, relations of economic and political power, origins and functions of economic institutions. The terrain is unsuitable for our tools. We find it hard to frame meaningful questions, much less to answer them. (James Tobin, Nobel Laureate)

This article discusses the possibility of the automation of sophisticated subject indexing of medical journal articles. Approaches to subject descriptor assignment in information retrieval research are usually either based upon the manual descriptors in the database or generation of search parameters from the text of the article. The principles of the Medline indexing system are described, followed by a summary of a pilot project, based upon the Amed database. The results suggest that a more extended study, based upon Medline, should encompass various components: Extraction of ‘concept strings’ from titles and abstracts of records, based upon linguistic features characteristic of medical literature. Use of the Unified Medical Language System (UMLS) for identification of controlled vocabulary descriptors. Coordination of descriptors, utilising features of the Medline indexing system. The emphasis should be on system manipulation of data, based upon input, available resources and specifically designed rules.
