This paper aims to apply a robust methodology to establish relationships between user-configurable process parameters of commercial desktop stereolithography (SLA) printers and dimensional accuracy of a custom-designed test artifact.

A detailed response surface methodology study, Box–Behnken incomplete factorial design of four factors with three levels, was carried out to evaluate process performance of desktop SLA printers. The selected factors were as follows: printing orientation angle in x-direction, printing orientation angle in y-direction, position on build platform in spatial x-coordinate, position on build tray in spatial y-coordinate and layer thickness. The proposed artifact was designed to include 12 feature groups including thin walls, holes, bosses, bridges and overhangs. Two responses were associated with the features: the dimensional deviation according to the designed value and the minimum feature size.

Layer thickness was the most significant factor in 70% of the analyzed responses. For example, measurement deviation was reduced about 90% when cylindrical holes were printed with the lowest layer thickness. Further, in many cases, dimensional deviation was minimized for features at the center of the platform, where the beam cures the resin in a straight line. However, at distant positions, accuracy could be improved by compensating for beam deviation by changing the object orientation angle.

The findings of this study can serve, both generally and specifically, for SLA designers and engineers who wish to optimize printing process variables and feature location to achieve high-dimensional accuracy and further understand the many coupled considerations among part design, build configuration and process performance.

The deadhead subculture – centered around the band Grateful Dead – has been active for 50+ years. Despite its longevity, academic work is sparse compared to other music subcultures. Given its durability and resilience, this subculture offers an opportunity to explore subcultural development and maintenance. I employ a contemporary, symbolic interactionist approach to trace the development of deadhead subculture and subcultural identity. Although identity is a basic concept in subculture research, it is not well defined: I suggest that the co-creation and maintenance of subcultural identity can be seen as a dialectic between collective identity and symbolic interactionist conceptions of individual role-identity.

It is widely agreed that transformation processes that are triggered by crisis events can challenge conventional behavioural norms and stimulate new ideas and innovations that can assist in the preparations for future challenges. This impetus for transformation processes not only applies to the COVID-19 pandemic, but has also been seen in many other instances, such as the Global Financial Crisis in 2008 or the 2011 Fukushima nuclear disaster, which have sparked significant socio-political change processes often with a global reach. The multitude of wicked tourism policy problems discussed in our book often occur in parallel, are of growing complexities, are often not well understood and indistinguishable from one another and exert pressure on the resilience of vulnerable political, economic and community-based systems. These circumstances often present as tipping points which can trigger necessary long-term transformations. However, this process of long-term change must be well planned and strategically implemented. Thus, future transformative destination management should be built on a holistic approach, underpinned by adaptive political leadership in which tourism is not only seen as a driver for economic growth and employment, but as a strategy which successfully integrates social, cultural and ecological goals.

In this chapter, we consider the fundamental importance of social identity both in terms of how people think about others and for personal well-being. The chapter reviews how social categorization and social identity impact people's responses to others and, drawing on our own work on the Common Ingroup Identity Model, examines how identity processes can be shaped to improve intergroup relations. This model describes how factors that alter the perceptions of the memberships of separate groups to conceive of themselves as members of a single, more inclusive, superordinate group can reduce intergroup bias. The present chapter focuses on four developments in the model: (1) recognizing that multiple social identities can be activated simultaneously (e.g., a dual identity); (2) acknowledging that the meaning of different identities varies for different groups (e.g., racial or ethnic groups); (3) describing how the impact of different social identities can vary as a function of social context and social and personal values; and (4) outlining how these processes can influence not only intergroup attitudes but also personal well-being, interms of both mental and physical health.

This study aims to empirically indicate that environment-friendly products may be used as a consumption strategy for improving the environmental well-being of a sizable consumer base and show that there are great possibilities and opportunities available for companies to come up with the right marketing mix for consumers in the rural market. There is a great dearth of empirical research on consumer behavior facets on environment-friendly products for rural market in India.

Conclusive cross-sectional descriptive research design has been used to study the environmentally concerned consumer behavior (ECCB) for environment-friendly products with the help of a survey instrument relevant for empirical research. This paper adds to the existing literature by developing one model in the Indian context for the rural market. The research study used exploratory factor analysis and confirmatory factor analysis with structural equation modeling approach to analyze the collected data from consumers.

The major finding of the study is that consumers living in rural areas are aware about the environmental movement, but marketers have probably not fully explored the potential for environment-friendly products. The study strongly argues that organizations should leverage on the rural market opportunity in India. It confirms the need to tailor marketing mix for rural markets for determining behavioral dimensions of consumer decision-making.

This empirical research paper is developed and applied in the Indian context, with special reference to the rural market of the country. Results may change when applied to different rural locations in the same country and/or different countries depending on their demographic variables, psychosocial factors and socioeconomic conditions. The findings of this study need to be viewed within the context of certain limitations of location, social and economic issues. The study provides the initial base for further research on the theme, as there are no such studies available on environment-friendly products.

This research study is highly useful for the business firms deciding on marketing mix variables for environment-friendly products in rural market scenario in India, and it provides inputs for formulating major policy decisions in marketing. The study provides insights for managers, policymakers and organizations operating in rural markets and working on different facets of environmental protection issues in different forms.

It has been investigated across global markets that human activities have altered the natural ecosystem, so to make natural resources available for the future generation, there is a greater need to achieve more sustainable forms of development. The study provides insights from the rural Indian market for better adoption of environment-friendly products and will motivate marketers to explore the rural market horizon.

The study has been conducted with consumers who are residents of one small town in India. So far, no study has been conducted, and it is first such attempt to analyze the rural Indian market for environment-friendly products and consumer behavior ever since such products were launched in the country. This study provides an early glimpse into the workings of marketing practitioners who work on consumer strategy formulation and rural marketing decision-making for environment-friendly products.

Over the past two decades, the application of most-favoured-nation (MFN) clauses in international investment agreements (IIAs) to dispute settlement matters has generated controversy. The purpose of this paper is to help resolve some of the controversies by examining the rule of law issues that may arise from such application of MFN.

The study describes controversies regarding the application of MFN to dispute settlement as per the extant literature on the subject. It explores the elements of rule of law in investor-state arbitration. The paper then analyses the implications of applying MFN to dispute settlement matters for the elements of rule of law. Based on such analysis, the study argues that the application of MFN to dispute settlement matters undermines certain elements of rule of law.

The paper has outlined the relevant elements of rule of law in investor-state arbitration as access to dispute settlement; judicial (or tribunal) independence, fairness and impartiality; consistency and predictability of law and decisions; transparency; accountability and subjection of dispute forums and systems to law. It found that the application of MFN undermines various components of rule of law, in particular of consistency and predictability and the requirement of tribunals to adjudicate within the limits of the law.

The findings of this study will help future investor-state arbitral tribunals to decide on the application of MFN to dispute settlement matters.
