The Cost

Although the textile industry has many products to offer to humanity, it consumes a lot of energy and indirectly causes greenhouse gas emissions. With increasing environmental awareness, parameters such as the cost and performance of each industrial activity to society, as well as the use of natural resources and the possibility of causing global environmental problems to have become more frequently considered factors. In the denim bleaching process, the desired effect is usually obtained with the help of sodium hypochlorite. Sodium metabisulfite is then used for the neutralization process. Since these processes are carried out at high liquor ratios, the waste load resulting from the consumption of necessary chemicals and water is also high. In this study, ecological bleaching methods have been developed as an alternative to the conventional sodium hypochlorite bleaching method by reducing the use of water and chemicals with low liquor and spraying bleaching methods. Denim garments subjected to bleaching with low liquor and spraying methods were compared with denim garments applied to sodium hypochlorite bleaching in industrial washing machines according to exhaustion method. In the spraying method, the mixture coming out of the narrow nozzle is mixed with the compressed air by means of a specially designed spray gun and sprayed in very small droplets. Thus, a good atomization is ensured, and a low liquor ratio water cloud is created.

Green Human Resource Management

Environmental conservation has been a concern to many international, local organizations and individuals for Centuries. Green management initiatives become an important factor in forward-thinking business around the world as a means of combating environmental degradation caused by organizations. Industrialization has contributed to the global environmental problems we are witnessing today and Tanzania industrialization drive cannot ignore this fact. Research is one of best ways for investigating, understanding and solving problems.  Although number of researches has been done on Green Human Resource Management (Green HRM), still there is no sufficient literature on the subject. To bridge this gap this study investigated the role of green recruitment and selection on performance of Processing Industries in Tanzania by using Tanzania Tobacco Processors Limited (TTPL) as a case study. The study sough to specifically assess the application of green recruitment and selection at TTPL, determining whether green recruitment and selection attract more and better job candidates, and establishing the relationship between green recruitment and selection and organizational performance. It was found that green recruitment and selection practices are in place and they contribute in attracting more qualified job candidates. The study also found a linear relationship between green recruitment and selection and performance. Further, the study recommends institutionalization of green recruitment and selection and other green HRM practices in order improve organizational performance. Regulatory and statutory bodies are recommended to ensure that green practices are put in place by organizations for organizational and environmental sustainability.

Abstract The main objective of this work is to develop a numerical analysis of a shredder machine to generate rubber particulate material for its implementation in different sectors such as construction, artisanal, and road as aggregates in the raw material. As part of the methodology, modern design theories were considered to select the materials for the different elements of the crushing machine; for this purpose, the SolidWorks design software was used to obtain a conceptual design model of the prototype. The mathematical and numerical results indicate that the prototype of the crushing machine will work in good conditions, always guaranteeing high levels of safety and performance based on the mechanical and physical properties of the materials selected through the design theories. Likewise, this machine will be low-cost to promote growth and competitive capacity for studies of different products with rubber aggregates to solve global environmental problems. Finally, the physical behavior of the new materials can be obtained with rubber particles aggregate will allow evaluating and optimizing a different kind of products that can be used in different sectors aiding sustainability sources.

Two Alternatives

It is now widely acknowledged that global environmental problems raise pressing social and political issues, but relatively little philosophical attention has been paid to their bearing on the concept of liberty. This must surprise us, because the question of whether environmental policies are at odds with individual liberty is bound to be controversial in the political arena. First, this article explains why a thorough philosophical debate about the relation between liberty and environmental constraints is needed. Second, based on Philip Pettit’s typology of liberty, it assesses how different conceptions of liberty fare in a context of stringent ecological limits. Indeed, a simple conceptual analysis shows that some conceptions of liberty are more compatible than others with such limits, and with the policies necessary to avoid overshooting them. The article concludes that Pettit’s conception of liberty as non-domination is more compatible with the existence of stringent ecological limits than the two alternatives considered.

The Impact

The quality of the software can be measured by its return on investment. Factors which may affect the return on investment (ROI) is the tangible factors (such as the cost) dan intangible factors (such as the impact of software to the users or stakeholder). The factor of the software itself are assessed through reviewing, testing, process audit, and performance of software. This paper discusses the consideration of return on investment (ROI) assessment criteria derived from the software and its users. These criteria indicate that the approach may support a rational consideration of all relevant criteria when evaluating software, and shows examples of actual return on investment models. Conducted an analysis of the assessment criteria that affect the return on investment if these criteria have a disproportionate effort that resulted in a return on investment of a software decreased.

Ecological Science

Robert May's seminal book has played a central role in the development of ecological science. Originally published in 1976, this influential text has overseen the transition of ecology from an observational and descriptive subject to one with a solid conceptual core. Indeed, it is a testament to its influence that a great deal of the novel material presented in the earlier editions has now been incorporated into standard undergraduate textbooks. It is now a quarter of a century since the publication of the second edition, and a thorough revision is timely. Theoretical Ecology provides a succinct, up-to-date overview of the field set in the context of applications, thereby bridging the traditional division of theory and practice. It describes the recent advances in our understanding of how interacting populations of plants and animals change over time and space, in response to natural or human-created disturbance. In an integrated way, initial chapters give an account of the basic principles governing the structure, function, and temporal and spatial dynamics of populations and communities of plants and animals. Later chapters outline applications of these ideas to practical issues including fisheries, infectious diseases, tomorrow's food supplies, climate change, and conservation biology. Throughout the book, emphasis is placed on questions which as yet remain unanswered. The editors have invited the top scientists in the field to collaborate with the next generation of theoretical ecologists. The result is an accessible, advanced textbook suitable for senior undergraduate and graduate level students as well as researchers in the fields of ecology, mathematical biology, environmental and resources management. It will also be of interest to the general reader seeking a better understanding of a range of global environmental problems.

Neoliberal Restructuring

Distinguished by extreme, systematized rationalism, Weber argued, bourgeois culture makes the social world in some ways more predictable and more comfortable but precludes a widely shared good life and social justice. He stressed emphatically that free-market capitalism, by maximizing formal rationality oriented to capital accounting and profitability, produces substantively “irrational” consequences that undermine the sociocultural and material fabric needed to sustain it. More than forty years of neoliberal restructuring, designed to accelerate capital accumulation at almost any cost, has generated massive corporate scandals, extreme economic inequalities, and global environmental problems that threaten its political legitimacy and social and ecological foundations. This chapter explores how Weber anticipated the types of substantive irrationalities suffered by today’s neoliberal regimes.

Setting the stage for the special forum, this introduction points to the centrality of science diplomacy activities within many current foreign policy concepts around the world. It also points to the lack of historical perspective within many current academic debates about science diplomacy. Suggesting the value of such a perspective, the introduction then draws attention to a number of fruitful contributions that histories of science diplomacy may make to contemporary history. These include: a better understanding of how entanglements between science, foreign policy, and international relations evolved over the twentieth century; a refined understanding of the workings of foreign relations and diplomacy that sheds light on the role of science as an arena of foreign relations; new insights into the Cold War; a globalizing of perspectives in the writing of contemporary history; a new international focus on widely under-researched actors like universities, science movements, science organizations, and science academies; a focus on new themes that range from global environmental problems to issues like cultural heritage. The remainder of the introduction then delineates some of the shared assumptions and findings of the essays and then briefly introduces each contribution to the special section.

The Relationship

In light of increasing concerns about global environmental problems, environmental moral education is assumed to have a significant influence on the pro-environmental behaviour of students. Within the past decade, several higher education institutes have acknowledged the importance of integrating sustainability into the educational curriculum to have a focused and explicit impact on society. The current study investigated the relationship between environmental moral education and pro-environmental behaviour while drawing upon insights from the conservation of resource theory. The relationship among the aforementioned variables was studied for the mediating role of psychological empowerment and the moderating effect of Islamic religiosity. Data were collected from 429 university students with a cross-sectional approach. The data were analysed using “structural equation modelling” and “PROCESS” analytical techniques. The results of the study followed the predicted conceptual model, that is, environmental moral education was positively related to pro-environmental behaviour. Furthermore, psychological empowerment partially mediated the aforementioned relationship, while Islamic religiosity moderated the relationships between environmental moral education and pro-environmental behaviour as well as between environmental moral education and psychological empowerment. These findings reinforce the importance of environmental moral education and Islamic religiosity in understanding the Muslim student’s ecological behaviours.
