Engineering in Transition. Approaches, strategies and technologies for implementing system innovation towards sustainability

With the aim to provide people with sustainable options, engineers are ethically required to hold the safety, health and welfare of the public paramount and to satisfy society's need for sustainable development. The global crisis and related sustainability challenges are calling for a fundamental change in culture, structures and practices. Sustainability Transitions (ST) have been recognized as promising frameworks for radical system innovation towards sustainability. In order to enhance the effectiveness of transformative processes, both the adoption of a transdisciplinary approach and the experimentation of practices are crucial. The evolution of approaches towards ST provides a series of inspiring cases which allow to identify advances in making sustainability transitions happen. In this framework, the thesis has emphasized the role of Transition Engineering (TE). TE adopts a transdisciplinary approach for engineering to face the sustainability challenges and address the risks of un-sustainability. With this purpose, a definition of Transition Technologies is provided as a valid instruments to contribute to ST. In the empirical section, several transition initiatives have been analysed especially at the urban level. As a consequence, the model of living-lab of sustainability has crucially emerged. Living-labs are environments in which innovative technologies and services are co-created with users active participation. In this framework, university can play a key role as learning organization. The core of the thesis has concerned the experimental application of transition approach within the School of Engineering and Architecture of University of Bologna at Terracini Campus. The final vision is to realize a living-lab of sustainability. Particularly, a Transition Team has been established and several transition experiments have been conducted. The final result is not only the improvement of sustainability and resilience of the Terracini Campus, but the demonstration that university can generate solutions and strategies that tackle the complex, dynamic factors fuelling the global crisis.

Comparative Analysis of Educational Attainment in Transition Economies

The project compared several indicators of educational attainment across various groups of transition economies, and between transition economies and others. The indicators of education reflected both the quantity of schooling (e.g. average years of schooling, percentage not attending school at all, and adult literacy rates) and schooling quality (e.g. public expenditure on education, pupil-teacher ratios, repetition rates, dropout rates, and international test scores). The basic test used in the project was a t-test on differences in sample means. Among the transition economies, the indicators examined were most favourable for central European, high-income and advanced transition countries, although the differences between these countries and the remaining transition countries were not usually statistically significant. When compared with other world economies, the transition countries typically showed significantly better indicators than developing countries, but differences between transition and developed countries were not statistically significant. The project also examined the behaviour of the correlation coefficient between indicators of education and income, which, as expected, were usually positive.

Changes in the Social Status of Women in Societies in Transition: Russia and Armenia

The project studied the way the post-communist transition has affected the position of women in society and two post-Soviet states, Armenia and Russia, were chosen for a comparative study. Although in many respects the two countries show rather similar tendencies, there are important differences. The most dramatic of these lie in the field of the women's movement and state support, in family lifestyles and public thinking, and in the perception of female roles in society by both women and men in both countries. Whereas in Russia, at least in large cities, it is possible to speak of a movement concerned with equality and women's rights, in Armenia there are few women's organisations and those that exist are most focused on support for children and poor families. In Russia, many post-Soviet changes can be described as a shift towards 'Western' rather than 'Eastern' values, while in Armenia this tendency is much weaker and exists alongside a relapse into traditional attitudes. Iskandarian suggests possible explanations for this, both intrinsic (tradition. motivation) and external (influences, neighbouring countries, involvement in wars, the economic situation, migrations, political regimes). Nevertheless, for both societies it is possible to speak of a growing awareness of women's needs and of the birth of a new tradition in family and public life brought by the post-Soviet winds of change.

Rhetorics and Practices of Modernisation in Russian Industry: a Reflective Analysis of Organisational Cultures in Transition

This research was based on the results of a case study of a large confectionery factory in the Russian city of Samara. The concept of paternalism is clear in many features of the life of Russian enterprises, including the rhetoric and strategy of the management, relationships within the labour force and the stereotypical expectations of workers. The concept also has a much wider bearing, embracing the spheres of state policy, the social, and family relationships, that is every sphere of social life in which the patriarchal, communal, stereotyped way of thinking of the Soviet people is reproduced. A substantial proportion of the state's role in providing social protection for the population is carried out through enterprises. In spite of low salaries and the absence of career opportunities, female workers were as strongly attached to the enterprise as to their homes. Romanov's research showed how the development of capitalism in industries in Russia is destroying the cultural and social identities of female workers and is contributing to gender inequality. Interpersonal relations are becoming increasingly utilitarian and distant and the basic features of the patriarchal type of administrative control are becoming blurred. This control is becoming more subtle, but gender segregation is preserved in the new framework and indeed becoming more obvious, being reproduced both at the departmental level and in the hiring policy of the enterprise as a whole.

Livelihoods in Transition: Changing Land Use Strategies and Ecological Implications in a Post Soviet Setting (Kyrgyzstan)

The sudden independence of Kyrgyzstan from the Soviet Union in 1991 led to a total rupture of industrial and agricultural production. Based on empirical data, this study seeks to identify key land use transformation processes since the late 1980s, their impact on people's livelihoods and the implication for natural resources in the communes of Tosh Bulak and Saz, located in the Sokuluk River Basin on the northern slope of the Kyrgyz Range. Using the concept of the sustainable livelihood approach as an analytical framework, three different livelihood strategies were identified: (1) An accumulation strategy applied by wealthy households where renting and/or buying of land is a key element; they are the only household category capable of venturing into rain fed agriculture. (2) A preserving strategy involving mainly intermediate households who are not able to buy or rent additional agricultural land; very often they are forced to return their land to the commune or sell it to wealthier households. (3) A coping strategy including mainly poor households consisting of elderly pensioners or headed by single mothers; due to their limited labour and economic power, agricultural production is very low and hardly covers subsistence needs; pensions and social allowances form the backbone of these livelihoods. Ecological assessments have shown that the forage productivity of remote high mountain pastures has increased from 5 to 22 per cent since 1978. At the same time forage productivity on pre-mountain and mountain pastures close to villages has generally decreased from 1 to 34 per cent. It seems that the main avenues for livelihoods to increase their wealth are to be found in the agricultural sector by controlling more and mainly irrigated land as well as by increasing livestock. The losers in this process are thus those households unable to keep or exploit their arable land or to benefit from new agricultural land. Ensuring access to land for the poor is therefore imperative in order to combat rural poverty and socio-economic disparities in rural Kyrgyzstan.

Distance education in transition

In his most recent publication, Against the Tide: Critics of Digitalisation, Otto Peters brings together some of the most formidable and critical voices and compelling perspectives on the potential hazards of digitalization. The viewpoints presented range from personal, anthropological, and pedagogical to more scientific and technical, and arise from multiple disciplines. Peters has long been a respected scholar in the field of distance education, and while Peters’ earlier work has advocated the affordances of digitalization, this latest book is an abrupt shift to the darker side of digitalization. The assembly of critics Peters has gathered come from around the world and different walks of life: journalists, educators, scientists, philosophers, lawyers, mathematicians, and computer scientists, to name a few. Their one shared bond is a deep-seated belief that digitalization will have a profound and lasting impact on humankind – and not only in positive ways. ...

Hepatic gene expression involved in glucose and lipid metabolism in transition cows: effects of fat mobilization during early lactation in relation to milk performance and metabolic changes.

Insufficient feed intake during early lactation results in elevated body fat mobilization to meet energy demands for milk production. Hepatic energy metabolism is involved by increasing endogenous glucose production and hepatic glucose output for milk synthesis and by adaptation of postcalving fuel oxidation. Given that cows differ in their degree of fat mobilization around parturition, indicated by variable total liver fat concentration (LFC), the study investigated the influence of peripartum fat mobilization on hepatic gene expression involved in gluconeogenesis, fatty acid oxidation, ketogenesis, and cholesterol synthesis, as well as transcriptional factors referring to energy metabolism. German Holstein cows were grouped according to mean total LFC on d 1, 14, and 28 after parturition as low [<200mg of total fat/g of dry matter (DM); n=10], medium (200-300 mg of total fat/g of DM; n=10), and high (>300 mg of total fat/g of DM; n=7), indicating fat mobilization during early lactation. Cows were fed total mixed rations ad libitum and held under equal conditions. Liver biopsies were taken at d 56 and 15 before and d 1, 14, 28, and 49 after parturition to measure mRNA abundances of pyruvate carboxylase (PC); phosphoenolpyruvate carboxykinase; glucose-6-phosphatase; propionyl-coenzyme A (CoA) carboxylase α; carnitine palmitoyl-transferase 1A (CPT1A); acyl-CoA synthetase, long chain 1 (ASCL1); acyl-CoA dehydrogenase, very long chain; 3-hydroxy-3-methylglutaryl-CoA synthase 1 and 2; sterol regulatory element-binding factor 1; and peroxisome proliferator-activated factor α. Total LFC postpartum differed greatly among cows, and the mRNA abundance of most enzymes and transcription factors changed with time during the experimental period. Abundance of PC mRNA increased at parturition to a greater extent in high- and medium-LFC groups than in the low-LFC group. Significant LFC × time interactions for ACSL1 and CPT1A during the experimental period indicated variable gene expression depending on LFC after parturition. Correlations between hepatic gene expression and performance data and plasma concentrations of metabolites and hormones showed time-specific relations during the transition period. Elevated body fat mobilization during early lactation affected gene expression involved in gluconeogenesis to a greater extent than gene expression involved in lipid metabolism, indicating the dependence of hepatic glucose metabolism on hepatic lipid status and fat mobilization during early lactation.
