Optimal and Long-Term Dynamic Transport Policy Design: Seeking Maximum Social Welfare through a Pricing Scheme

This article presents an alternative approach to the decision-making process in transport strategy design. The study explores the possibility of integrating forecasting, assessment and optimization procedures in support of a decision-making process designed to reach the best achievable scenario through mobility policies. Long-term evaluation, as required by a dynamic system such as a city, is provided by a strategic Land-Use and Transport Interaction (LUTI) model. The social welfare achieved by implementing mobility LUTI model policies is measured through a cost-benefit analysis and maximized through an optimization process throughout the evaluation period. The method is tested by optimizing a pricing policy scheme in Madrid on a cordon toll in a context requiring system efficiency, social equity and environmental quality. The optimized scheme yields an appreciable increase in social surplus through a relatively low rate compared to other similar pricing toll schemes. The results highlight the different considerations regarding mobility impacts on the case study area, as well as the major contributors to social welfare surplus. This leads the authors to reconsider the cost-analysis approach, as defined in the study, as the best option for formulating sustainability measures.

Towards the social inclusion of youth: Tools for analysis and policy design

The integration of youth into development processes is crucial in order to advance towards more egalitarian societies. Over the past few years, the Economic Commission for Latin America and the Caribbean (ECLAC) has regarded equality as the horizon for development, structural change as the way to achieve it, and policy as the instrument to reach that horizon. Equality is viewed as going beyond the distribution of means, such as monetary income, to include equal opportunities and capacities. This implies understanding equality as the full exercise of citizenship, with dignity and the reciprocal recognition of actors. Progress in this direction requires policies that promote the autonomy of subjects and pay attention to their vulnerabilities.

A probabilistic switch model of information flow in social networks: Application for virtual circuits to organizational design

Network building and exchange of information by people within networks is crucial to the innovation process. Contrary to older models, in social networks the flow of information is noncontinuous and nonlinear. There are critical barriers to information flow that operate in a problematic manner. New models and new analytic tools are needed for these systems. This paper introduces the concept of virtual circuits and draws on recent concepts of network modelling and design to introduce a probabilistic switch theory that can be described using matrices. It can be used to model multistep information flow between people within organisational networks, to provide formal definitions of efficient and balanced networks and to describe distortion of information as it passes along human communication channels. The concept of multi-dimensional information space arises naturally from the use of matrices. The theory and the use of serial diagonal matrices have applications to organisational design and to the modelling of other systems. It is hypothesised that opinion leaders or creative individuals are more likely to emerge at information-rich nodes in networks. A mathematical definition of such nodes is developed and it does not invariably correspond with centrality as defined by early work on networks.

Product design in the context of the social needs in less industrialised economies

This thesis is related to the subject of technical innovation, specifically to the activity of design in microenterprises operating in less industrialised economies. Design here is understood as a process, which is not the sole domain of formally trained categories such as engineers, architects or industrial designers. The 'professional boundary' discussion in this investigation is perceived as secondary as, in this context, products are designed, copied or adapted by workers, entrepreneurs themselves, or directly by the poor community. Design capacity at this level is considered to be important both in relation to the conception of capital and consumer goods and to the building up of technical knowledge. Although professional design emerged in Latin America little over three decades ago, this activity has remained marginalised throughout industry. Design activity tends to be concentrated in some product categories in the formalised industrial sector. For microenterprises operating informally, industrial design appears to be unknown. The existing literature pays little attention to 'informal design' capacity. Other areas of knowledge, such as development economies, recognise the importance of microenterprises and technological capability but neglect the potential role of industrial design in small manufacturing units. The management literature, though it focuses on technical innovation and design, has also paid little attention to 'informal design'. In less industrialised economies this neglect is felt by the lack of programmes specifically tailored to create or stimulate 'informal design'. There is a need for recognition of 'informal design' capacity and for the implementation of programmes which specifically target design as a central activity in the manufacturing firm, independent of their size and technological capability. Addressing 'design by the poor for the poor', requires a down-to-earth approach.

Senior management leadership, social support, job design and stressor-to-strain relationships in hospital practice

Purpose: The purpose of this paper is to examine the effect of the quality of senior management leadership on social support and job design, whose main effects on strains, and moderating effects on work stressors-to-strains relationships were assessed. Design/methodology/approach: A survey involving distribution of questionnaires was carried out on a random sample of health care employees in acute hospital practice in the UK. The sample comprised 65,142 respondents. The work stressors tested were quantitative overload and hostile environment, whereas strains were measured through job satisfaction and turnover intentions. Structural equation modelling and moderated regression analyses were used in the analysis. Findings: Quality of senior management leadership explained 75 per cent and 94 per cent of the variance of social support and job design respectively, whereas work stressors explained 51 per cent of the variance of strains. Social support and job design predicted job satisfaction and turnover intentions, as well as moderated significantly the relationships between quantitative workload/hostility and job satisfaction/turnover intentions. Research limitations/implications: The findings are useful to management and to health employees working in acute/specialist hospitals. Further research could be done in other counties to take into account cultural differences and variations in health systems. The limitations included self-reported data and percept-percept bias due to same source data collection. Practical implications: The quality of senior management leaders in hospitals has an impact on the social environment, the support given to health employees, their job design, as well as work stressors and strains perceived. Originality/value: The study argues in favour of effective senior management leadership of hospitals, as well as ensuring adequate support structures and job design. The findings may be useful to health policy makers and human resources managers. © Emerald Group Publishing Limited.

Nvidia, matrox, paper? - Undergraduate game design tools in the humanities and social sciences

Eschewing costly high-tech approaches, this paper looks at the experience of using low-tech approaches to game design assignments as problem based learning and assessment tool over a number of years in undergraduate teaching. General game design concepts are discussed, along with learning outcomes and assessment rubrics in line with Blooms Taxonomy based on evidence from students who had no prior experience of serious game play or design. Approaches to creating game design based assessments are offered.

Design as Symbolic Violence. Design for Social Justice.

Design embeds ideas in communication and artefacts in subtle and psychologically powerful ways. Sociologist Pierre Bourdieu coined the term ‘symbolic violence’ to describe how powerful ideologies, priorities, values and even sensibilities are constructed and reproduced through cultural institutions, processes and practices. Through symbolic violence, individuals learn to consider unjust conditions as natural and even come to value customs and ideas that are oppressive. Symbolic violence normalises structural violence and enables real violence to take place, often preceding it and later justifying it. Feminist, class, race and indigenous scholars and activists describe how oppressions (how patriarchy, racism, colonialism, etc.) exist within institutions and structures, and also within cultural practices that embed ideologies into everyday life. The theory of symbolic violence sheds light on how design can function to naturalise oppressions and then obfuscate power relations around this process. Through symbolic violence, design can function as an enabler for the exploitation of certain groups of people and the environment they (and ultimately ‘we’) depend on to live. Design functions as symbolic violence when it is involved with the creation and reproduction of ideas, practices, tools and processes that result in structural and other types of violence (including ecocide). Breaking symbolic violence involves discovering how it works and building capacities to challenge and transform dysfunctional ideologies, structures and institutions. This conversation will give participants an opportunity to discuss, critique and/or develop the theory of design as symbolic violence as a basis for the development of design strategies for social justice.

I Stood Up: Social Design in Practice

Through practice-based research, we explore how interdisciplinary design projects can function to address social issues concerning environmental and social problems. Using two case studies developed between London in the United Kingdom, and Delhi and Ahmedabad in India, we discuss the importance of engagement with the people who the design ultimately serves. Finally, we argue that design concerned with complex social problems require equally complex, multidimensional responses, informed by bodies of knowledge, practices and approaches that lie outside of traditional design approaches.

La accesibilidad universal y el diseño para todas las personas factor clave para la inclusión social desde el design thinking curricular

En este artículo se presenta el diseño de la nueva formación en intervención social para todas las personas desde la accesibilidad universal, en concreto el caso de las profesiones sociales, a través de la metodología del design thinking curricular. En el mismo se trata la relación íntima que surge de vincular dos conceptos, por un lado la inclusión –que responde positivamente a la diversidad de las personas y a las diferencias individuales, entendiendo que la diversidad no es un problema, sino una oportunidad para el enriquecimiento de la sociedad, a través de la participación activa en la vida familiar, en la educación, en el trabajo y en general en todos los procesos sociales, culturales y en las comunidades (UNESCO, 2005)– y, por otro, la accesibilidad, como nuevo paradigma de la integralidad en la intervención de los/as nuevos/as profesionales dedicados al sector social, haciendo realidad el concepto de ciudadanía en sentido amplio.

SMART social science? Examining the nature and role of social scientific expertise in institutional design

Daniel Bromley argues against Oran Young’s FIT model as a basis for environmental governance, on the grounds that humans cannot manage nature and that attempts to do so are based on a scientistic, modernist conceit. At issue is the role of natural and social scientists in adjudicating questions about what we ought to do to close governance gaps and address unsustainable behaviors. If Bromley is right, then the lessons of the American pragmatist tradition recommend against attempts to “fit” social institutions to the natural world. The first objective of this paper is to argue that Bromley’s view is not in keeping with the pragmatism of C. S. Peirce and John Dewey, which actually places a high value on natural and social scientific modes of inquiry in the service of social ends. I argue that Young’s proposal is in fact a development of the pragmatist idea that social institutions must be fit in the sense of fitness, i.e., resilient and able to navigate uncertainty. Social institutions must also evolve to accommodate the emerging values of the agents who operate within them. The second objective of this paper is to examine the role of social science expertise in the design of social policies. Governance institutions typically rely on the testimony of natural scientists, at least in part, to understand the natural systems they operate within. However, natural systems are also social systems, so it seems pertinent to ask whether there is a role for social systems experts to play in helping to design environmental governance institutions. I argue that social scientists can make a unique contribution as experts on social institutions, and as such, are necessary to bring about a transformation of the unsustainable institutions that are preventing us from achieving stated sustainable development goals.

ADVERTISEMENT ALLOCATION AND TRUST MECHANISMS DESIGN IN SOCIAL NETWORKS

Social network sites (SNS), such as Facebook, Google+ and Twitter, have attracted hundreds of millions of users daily since their appearance. Within SNS, users connect to each other, express their identity, disseminate information and form cooperation by interacting with their connected peers. The increasing popularity and ubiquity of SNS usage and the invaluable user behaviors and connections give birth to many applications and business models. We look into several important problems within the social network ecosystem. The first one is the SNS advertisement allocation problem. The other two are related to trust mechanisms design in social network setting, including local trust inference and global trust evaluation. In SNS advertising, we study the problem of advertisement allocation from the ad platform's angle, and discuss its differences with the advertising model in the search engine setting. By leveraging the connection between social networks and hyperbolic geometry, we propose to solve the problem via approximation using hyperbolic embedding and convex optimization. A hyperbolic embedding method, \hcm, is designed for the SNS ad allocation problem, and several components are introduced to realize the optimization formulation. We show the advantages of our new approach in solving the problem compared to the baseline integer programming (IP) formulation. In studying the problem of trust mechanisms in social networks, we consider the existence of distrust (i.e. negative trust) relationships, and differentiate between the concept of local trust and global trust in social network setting. In the problem of local trust inference, we propose a 2-D trust model. Based on the model, we develop a semiring-based trust inference framework. In global trust evaluation, we consider a general setting with conflicting opinions, and propose a consensus-based approach to solve the complex problem in signed trust networks.
