Public transportation can be viewed as a key determinant and consequence of the social and spatial formation and development of contemporary cities and regions. Transportation policy generally combines four categories of instruments, i.e., investment, pricing, regulation and subsidy, to generate viable alternatives. Capital investment in public transportation supports the purchase of equipment and facilities including rolling stock, tracks, control equipment, and the construction of terminals, stations, parking lots, maintenance facilities and power generating facilities. Risk governance for public transportation investments looks at how risk-related decision-making unfolds when a range of actors is involved, requiring co-ordination and possibly reconciliation between a profusion of roles, perspectives, goals and activities. In this paper, a two-phased multicriteria methodology is proposed to select the best investment alternative for public transportation with respect to the predetermined criteria. In the first phase, a selection among transportation types is made, and in the second phase, a selection among transportation modes of the selected transportation type is made. A case study for Istanbul is given in the application section.

29 oriented and 10 nonoriented coal samples are collected in the study from three different regions of the Huaibei coalfield, eastern China, and their vitrinite reflectance indicating surface (RIS) parameters are systematically calculated and analyzed. Using the available methods, Kilby’s transformations and RIS triaxial orientations are obtained. The magnitudes and orientations of the RIS axes of the three regions were respectively projected on the horizontal planes and vertical sections. The results show that the samples in high deformed region have significant anisotropy magnitudes (higher Bw/Rmax and Ram values) with a biaxial negative style, whereas the samples in the slightly deformed area have unimpressive anisotropy magnitudes with a biaxial negative style. Thermal metamorphism superposed might enhance the complication and variation of RIS style. RIS projection analysis deduced that the RIS orientation is mainly controlled by regional tectonic stress, and likely influenced by deformation mechanisms of coal.

Purpose – This paper aims to investigate how dynamic capabilities enabled survival in a select group of brewers, during one of the lengthiest and most severe industry consolidations in history. In doing so, we advance Abell’s (1978) theory of strategic windows through integration with the resource-based view of the firm. Design/methodology/approach – Using a mixed method approach, we first apply case study methods to develop hypotheses around the timing and level of operational capability required for survival. In the second phase, we test these hypothesized estimations on the USA Brewing population. Findings – Indicate that brewers which had advanced distribution and manufacturing operational capabilities before the strategic window of opportunity closed had higher survival rates. Practical implications – This study reinforces the importance of making timely strategic investments in capabilities. Originality/value – The integration of strategic window and capability theories advances our understanding of the roles that capabilities and time play in determining firm survival.

Back lanes are ubiquitously found in every city as they are a required component according to the by-laws. The intention of back lane is to serve as a service road and consequently society tends to neglect and had led to a forgotten public space due to its lack of maintenance. Thus, this has discouraged the pedestrian movement as it is unsafe because the laneway is mainly hidden from public eye. Therefore, it became a space for undesirable activities to be taken place especially for hoodlums. In line with the Kuala Lumpur Tourism Master Plan 2015-2025, that gives emphasise to revitalise forgotten spaces, this research looks into the issues of back lanes in Petaling Street with the aims to unlock its potentials. The study adopted a qualitative approach through 2 phases. The first phase is through literature review to study and understand its historical background follows by site observation through photographs and recording of the site existing conditions. The second phase is through interviews with urban planning experts and business owners to discuss the historical value, issues and parameters to revitalize the back lane. The outcome of the research divulges that revitalization of back lane and shifting the front façade to the back lane or adapting to a double façade are able to greet the public with new urban social spaces and that tenants are able to utilize and give it a new meaning.

Open access (OA) publications play an important role for academia, policy-makers, and practitioners. Universities and research institutions set up OA policies and provide authors different types of support for engaging in OA activities. This paper presents a case study on OA publishing in a scholarly community, drawing on qualitative and quantitative data gained from workshops and a survey. As the authors are the managing editors of the OA eJournal for eDemocracy and Open Government (JeDEM), the aim was to collect data and insights on the publication choices of authors interested in OA publishing and other crucial factors such as personal attitudes to publishing, institutional context, and digital literacy in order to improve the journal. In the first phase, two workshops with different stakeholders were held at the Conference for e-Democracy and Open Government (CeDEM) held in Austria and in South Korea in 2016. In the second phase, an online survey was sent to all the users of the e-journal JeDEM in October 2019. From the workshops, key differences regarding OA perception and strategies between the stakeholder groups were derived. Participants strongly perceived OA publishing as a highly individualist matter embedded within a publishing culture emphasizing reputation and rankings. The survey results, however, showed that institutional support differs considerably for authors. Factors such as visibility, reputation, and impact play the biggest role for the motivation to publish OA. The results from both inquiries provide a better understanding of OA publishing attitudes and the relevant digital literacies but also suggest the need to investigate further the enablers or difficulties of scholarship, particularly in a digital context. They clearly point to the potential of regularly addressing the users of the journal as well as communicating with them the more nuanced aspects of OA publishing, non-traditional metrics, or respective digital literacies, in order to reduce misconceptions about OA and to support critical stances.

Abstract Virtual polymeric materials were created and used in computer simulations to study their behavior under uniaxial loads. Both single-phase materials of amorphous chains and two-phase polymer liquid crystals (PLCs) have been simulated using the molecular dynamics method. This analysis enables a better understanding of the molecular deformation mechanisms in these materials. It was confirmed that chain uncoiling and chain slippage occur concurrently in the materials studied following predominantly a mechanism dependent on the spatial arrangement of the chains (such as their orientation). The presence of entanglements between chains constrains the mechanical response of the material. The presence of a rigid second phase dispersed in the flexible amorphous matrix influences the mechanical behavior and properties. The role of this phase in reinforcement is dependent on its concentration and spatial distribution. However, this is achieved with the cost of increased material brittleness, as crack formation and propagation is favored. Results of our simulations are visualized in five animations.

This paper describes how the Shack Dwellers Federation of Namibia developed the capacity to undertake enumerations and mapping of informal settlements and, with support from the national government and a local NGO, developed the Community Land Information Programme. Through this initiative, the federation has profiled and mapped all of the informal settlements in Namibia, covering more than 500,000 people without secure land tenure and setting a significant precedent in terms of the ability of the federation to work at scale. For each settlement, a profile was developed by the residents that stimulated discussions of their priorities and also discussions with government. In the second phase, the residents of informal settlements were supported to undertake more detailed enumerations and mapping to identify development priorities and provide the information needed for development initiatives. The paper describes how this was done in a case study of an informal settlement in Swakopmund municipality and ends with a discussion of what has been learned, especially with regard to keeping the process rooted in the concerns and priorities of the residents of each settlement.
