The cumulative environmental challenge of sustainable development in the twenty-first century is larger than anything humanity has ever had to deal with in the past. The good news is that solid progress is being reached in the understanding of issues in scientific terms and understanding what needs to be done. The bad news is twofold. First, although many of the environmental problems of earlier centuries are now being confronted, a new generation of difficulties is eclipsing what were the older difficulties. Secondly, much of the progress is being achieved by the wealthier parts of the planet, rather than the developing world. From population growth to climate change to unprecedented habitat and species loss, whether environmental sustainability can be achieved in the twenty-first century is an open question.

During the past two decades, there has been a significant growth of sociological studies into the ‘body pedagogics’ of cultural transmission, reproduction and change. Rejecting the tendency to over-valorise cognitive information, these investigations have explored the importance of corporeal capacities, habits and techniques in the processes associated with belonging to specific ‘ways of life’. Focused on practical issues associated with ‘knowing how’ to operate within specific cultures, however, body pedagogic analyses have been less effective at accounting for the incarnation of cultural values. Addressing this limitation, with reference to the radically diverse norms involved historically and contemporarily in ‘vélo worlds’, I develop Dewey’s pragmatist transactionalism by arguing that the social, material and intellectual processes involved in learning physical techniques inevitably entail a concurrent entanglement with, and development of, values.

Abstract The science associated with mineral nutrition is evolving at an accelerated pace. Some topics of investigation have persisted for decades; typical examples include clarification of mineral requirements, evaluation of mineral sources, definition of mineral bioavailability and physiological and metabolic interactions among minerals, to name a few. The fact that these topics have endured for so long serves to illustrate their importance to our craft, as well as the increasing sophistication of the science available to delve more deeply into our understanding of mineral nutrition. Newer topics that involve minerals directly and/or indirectly are attracting increasing attention – and for good reason. As one example, there is a growing body of data pointing to oxidative stress as a relevant issue in modern pork production. As another, the interaction of minerals with fiber has received considerable interest in the past, but recently, the topic has been further elevated by health and environmental concerns. While the above might be considered typical classical nutrition topics, mineral nutrition can also be viewed in a more holistic manner. To what extent is mineral nutrition involved in the observed increase in sow mortality in the past decade? How can and should mineral nutrition be included in precision feeding programs? What further roles of mineral nutrition might be involved in environmental sustainability? Where do we stand on the involvement of mineral nutrition in acid-base balance and does it have greater value in production today than previously considered? This presentation will consider current examples of how mineral nutrition impacts applied swine nutrition as well as overall pork production.

The past, or the perception of the past, plays a pivotal role in the formation of modern policies on land-use, since the rhetoric of conservation favours the protection of ‘ancient’ or ‘pristine’ landscapes, whilst the focus on economic or environmental sustainability has led to the endorsement of apparently long-lived ‘indigenous’ practices, especially where these appear to have permitted extended periods of cultivation whilst conserving local soil, water, and forest resources. Focusing on examples of locally developed intensive agriculture from Kenya and northern Tanzania, this chapter aims to highlight how the history of landscape management in these areas—although still poorly understood—continues to be cited within developmental and conservationist debates. It will outline how a combination of archaeological, historical, and palaeoenvironmental research might be employed to produce a more complete understanding of these agronomies, and argues that work of this kind is essential to qualify the historical assumptions that have been used to justify external intervention. The invocation of historical arguments in support of either economic intervention or wildlife conservation is not a recent phenomenon, but the critical appraisal of such arguments has gained momentum over the last two to three decades. It is by no means a coincidence that this is also the period that has seen a rise in interest in the precepts of ‘historical ecology’ (e.g. Balée 2006; Crumley 1994) and in resilience theory (e.g. Walker et al. 2004), both of which emphasize the need to study social, economic, and environmental factors from a long-term historical perspective in order to fully understand the relationships between them in any given place or time, and both stress the importance of seeing modern landscapes and resource exploitation strategies as legacies of former periods of land-use. More recently, a resurgence in interest in world systems theory—itself formerly influential on developmental thinking via dependency theory (e.g. Frank 1969)—raises similar themes through the notion that most if not all local economies have been influenced by their interaction with broader webs of trade relations at regional and global scales for several centuries (e.g. Hornberg and Crumley 2007).

We propose addressing an organization’s adoption of an environmental certification as a multicriteria problem considering environmental sustainability as well as economic and strategic aspects. Our methodological approach uses the Analytical Hierarchy Process (AHP), which we use in an empirical application to analyze the adoption decision of several Costa Rican firms and institutions. Firstly, we select a set of economic, strategic, and environmental criteria that seem relevant for the organization’s direction. We select these criteria according to our literature review and a series of face-to-face interviews with scholars and companies’ managers. As an environmental certification, we focus on Carbon Neutral (CN), which is a domestic certification aimed at reducing or offsetting carbon emissions. For the sake of comparison, we also consider ISO 14001, which is a well-known international standard aimed at compliance with environmental norms. We conduct the AHP analysis using the answers given by 24 companies and institutions, which in aggregate terms, give CN a higher score than ISO 14001. This result is mainly due to the fact that CN ranks above ISO 14001 when attending to environmental sustainability, although ISO 14001 tends to be preferred in economic and strategic terms.

Green Computing has attracted concerns in the past few decades, with the sole concern for the procedures involve in the designing, manufacturing, usage and disposal of information and communication technology (ICT) basically for environmental sustainability. The importance of human factor in green computing has not received the deserved attention. The social, moral and ethical decadence resulting from the use of ICT has reduced the quality of human in modern time. This study advocates the importance of peopleware as essential aspect of green computing which equalling demands concern. Thus the adoption of peopleware in green computing practices will invariably improve sustainability of the physical and spiritual environment.

The European Green Deal (EGD), launched by the European Commission in December 2019, is a major policy package addressing climate change and aiming at a “just and inclusive” transition. Several shortcomings can be identified in the EGD: it lacks a vision of a just, post-carbon economy for Europe; available resources are inadequate to reach stated objectives; and implementation tools are limited. We argue that making Europe’s production systems carbon neutral would require a broader range of “green” industrial policies that need to jointly address environmental sustainability, structural change, and fairness of economic outcomes in Europe.

The adsorption of proteins at the solid-liquid interface is a process of fundamental importance in nature. Extensive reviews (MacRitchie, 1978; Andrade & Hlady, 1986; Norde, 1986) testify to the strong interest which has been shown in the problem during the past few decades. Norde & Lyklema (1978) have rightly pointed out that protein adsorption is scientifically intriguing; the phenomenology is complicated and includes many presently apparently irreconcilable observations.

The addition of essential amino acids to all-vegetable diets, so as to raise the biological value of their proteins to the level of animal-protein concentrates, has often been advocated in the past by animal nutritionists. This aim was frustrated in practice since it was impossible, until recently, to secure the necessary supplies at prices that would make such additions economical. Feeding stuffs with added amino acids are now being sold commercially. This is possible following the manufacture of synthetic DL-methionine and crude L-lysine monochloride.It seemed desirable, therefore, to carry out investigations into the potential value of these amino acids to the pig feeder. This paper deals with the effect on growth, food utilization and retention of nitrogen of adding small amounts of lysine and methionine to the diet. An attempt is made to correlate the amino acid composition of the pig's diet with its rate of growth, the energy supply being adequate.

Purpose – The purpose of this paper is to identify three critical ingredients that are necessary to support the upcoming Green Paradigm. Existing research indicates the uprising of Green Paradigm through emergence of Green products and services. Extant literature discusses critical questions such as “what” and “how” in silos. Each of the ingredients is anchored in literature, highlighting the past, showcasing the gap and proposing future direction. Design/methodology/approach – Fundamentally, a combination of literature review and qualitative technique is used to achieve the main objective of the paper. Findings – Gaps in the literature support and suggest the need to focus on three different perspectives: corporate, management research and management education, which needs to be looked from a long range to support Green Paradigm. This finding is substantiated through qualitative research. Research limitations/implications – The limitation of the research is, only a 10 year period is considered for key word search in journals. The journals are restricted to top journals as given by UT Dallas research rankings, 2011. It is quite possible that there are other journals that focus more heavily on green perspective. Originality/value – This paper introduces a holistic perspective that fits all major lenses of the society to foster Green Paradigm, in turn, environmental sustainability.
