Abstract
Purpose – The purpose of this chapter is to propose a cross-assessment model as an analytical tool for developing sustainable urban transport and land-use strategies for a low-carbon society.
Methodology – A cross-assessment model is developed based on demand and supply models of transport services. The model is able to generate a set of the optimal service levels in public transport reflecting selected target strategies. It is applied to an impact analysis of public transport and land-use strategies in 2030 for all of Japan's 269 urban areas,with outcomes – including the financial balance of public transport operation, user benefits and CO2 emissions reduction – compared among strategies and urban areas.
Findings – The analytical results show that three value factors of efficiency, equity and the environment do not necessarily conflict with each other. In particular, it is clarified that CO2-emission reduction targets can contribute to the improvement of both financial balance and user benefits at the national level. In addition, the results of comparative analysis among the land-use and transport integration (LUTI) scenarios demonstrate that a combination of urban transport strategies and land-use control in the form of ‘corridors and multi-centres’ provides greater emission reduction and increased user benefits.
Implications – The cross-assessment model developed in this chapter could serve as an analytical tool for strategic transport planning. The results in this chapter underlinethe benefit of LUTI strategies particularly in China.

Abstract
Purpose – The purpose of this chapter is to project the global emergence of megacities through the 21st century using population scenarios consistent with the Special Report on Emissions Scenarios (SRES) of the Intergovernmental Panel on Climate Change (IPCC).
Methodology – A dynamic urban growth model is developed based on a scale-independent theory of growing networks taking into consideration the geographical and climatic suitability of the location of cities. The model is able to generate a series of megacity projections consistent with an experimental city size distribution based on a national urban population scenario consistent with Zipf's law. The model is applied to population projections for 45,316 cities around the world using three population scenarios from SRES.
Findings – All of the projections indicate that a large number of megacities will be generated in developing regions towards 2100, although the range is wide and depends on the population assumed in the scenarios. Some results indicate an extreme population concentration in megacities; this might be undesirable for national security, quality of life, and sustainable development. Transport policies affect urban growth and national land development through changes in mobility and accessibility across the nation.
Implications – The results presented in this chapter could serve to stimulate discussions on urban and national transport policies and planning, particularly in China.

Abstract
Studies in psychology have long revealed that making personal choice involves multiple motivational consequences. It has only been recent, however, that the literature on neuroscience started to examine the neural underpinnings of personal choice and motivation. This chapter reviews this sparse, but emergent, body of neuroscientific literature to address possible neural correlates underlying personal choice. By conducting the review, we encourage future systematic research programs that address this topic under the new realm of “autonomy neuroscience.” The chapter especially focused on the following motivational aspects: (i) personal choice is rewarding, (ii) personal choice shapes preference, (iii) personal choice changes the perception of outcomes, and (iv) personal choice facilitates motivation and performance. The reviewed work highlighted different aspects of personal choice, but indicated some overlapping brain areas – the striatum and the ventromedial prefrontal cortex (vmPFC) – which may play a critical role in motivational processes elicited by personal choice.

Abstract
Purpose
This study aims to propose a novel viscoelastic–viscoplastic combined constitutive model for glassy amorphous polymers within the framework of thermodynamics at finite strain that is capable of capturing their rate-dependent inelastic mechanical behavior in wide ranges of deformation rate and amount.
Design/methodology/approach
The rheology model whose viscoelastic and viscoplastic elements are connected in series is set in accordance with the multi-mechanism theory. Then, the constitutive functions are formulated on the basis of the multiplicative decomposition of the deformation gradient implicated by the rheology model within the framework of thermodynamics. Dynamic mechanical analysis (DMA) and loading/unloading/no-load tests for polycarbonate (PC) are conducted to identify the material parameters and demonstrate the capability of the proposed model.
Findings
The performance was validated in comparison with the series of the test results with different rates and amounts of deformation before unloading together. It has been confirmed that the proposed model can accommodate various material behaviors empirically observed, such as rate-dependent elasticity, elastic hysteresis, strain softening, orientation hardening and strain recovery.
Originality/value
This paper presents a novel rheological constitutive model in which the viscoelastic element connected in series with the viscoplastic one exclusively represents the elastic behavior, and each material response is formulated according to the multiplicatively decomposed deformation gradients. In particular, the yield strength followed by the isotropic hardening reflects the relaxation characteristics in the viscoelastic constitutive functions so that the glass transition temperature could be variant within the wide range of deformation rate. Consequently, the model enables us to properly represent the loading process up to large deformation regime followed by unloading and no-load processes.

Abstract
Purpose
The Greater Mekong Sub-region (GMS) is noted as an investment destination recently. However, there are few surveys about this region. In particular, direction of the regional disparity and economic linkage cannot be found, although it is inevitable to formulate economic or business policies. The paper aims to discuss these issues.
Design/methodology/approach
First, the author calculated the regional GINI coefficient of the GMS, converting the per capita GDP using the purchasing power parity. Then, the trend of intra-regional trade was calculated by using the data of Direction of Trade Statistics of IMF. In addition to that, to consider the trade structures, bilateral trades of Thailand with Vietnam, Laos and Myanmar were analyzed.
Findings
This paper made clear that the regional disparity of the GMS has been gradually shrinking from serious level to moderate in recent years, although it is still larger than the disparity of ASEAN original members. Two Chinese districts and Vietnam played an important role to improve the disparity. As for the intra-regional trade, it used to be very poor in the early 1990s, but is increasing in these years. There may be some signs of starting of the intra-industrial trade between Thailand and Vietnam, although trades with lower developed countries such as Laos and Myanmar are led by natural resources-related products.
Originality/value
This paper is the first survey to calculate the regional disparity of the GMS with time series data. The analysis of the intra-trade among the GMS members expresses the current situation of the economic linkage of this area.

Abstract
This chapter focuses on ways libraries can ensure the services and collections they provide do not exclude bisexual people and indulge in the “bi erasure” that is otherwise so prevalent in society. The authors share best practices for public, academic, and school libraries to add bisexual/pansexual titles to their collections, as well as provide programmatic tips that include the larger bisexual/pansexual community. Most importantly, the authors highlight community partners, advocacy organizations, or non-profits that can serve as potential collaborators as librarians brainstorm programming for bisexual/pansexual patrons. This chapter also contains staff training guidelines and resources for creating a more welcoming environment for bisexual/pansexual patrons. The chapter concludes with a list of resources that will help librarians make more inclusive collections’ decisions and resource guides. It’s purpose is to help libraries better serve bisexual/pansexual patrons who are undoubtedly already library users.

Abstract
This chapter explores what video games can teach us in light of the ongoing sixth mass extinction in the history of our planet, allegedly caused by global warming and the over-consumption of vital resources. Games made and played by nonhuman actors can shed light on the situatedness and partiality of our knowledge regarding the boundaries that separate and differentiate human and nonhuman, interactivity and passivity, entertainment and boredom, and life and death. Nonhuman games help us to articulate the space and time in-between these dualisms and have the potential to re-route gaming (and game studies) from false myths of agency, interactivity, and instrumentalism, and the masculinism inherent in these notions. Nonhuman games are companions for earthly survival, and as such they can be taken as useful references when considering a more ethical approach to the ecological crisis of the Anthropocene. The chapter investigates notions of posthumanism, interpassivity, and contemporary critiques of the early assumptions of game studies on the agency of human players. It looks at video games that play by themselves, idle and incremental games, and the emergence of nonplaying characters in ludic and open-world simulations. It explores forms of automatic play and the use of bots and Artificial Intelligence (AI) in online role-playing games, procedurally generated virtual environments, and games that far exceed the lifespan of their players.
