The Impact

Danwei (working unit) and Xiaoqu (residential community) are two typical and unique structural urban elements in China. The interior roads of Danwei and Xiaoqu are usually not accessible for the public. Recently, there is a call for opening these interior roads to the public to improve road network structure and optimize traffic flow. In this paper we investigate the impact of Danwei and Xiaoqu on their neighbouring traffic quantitatively. By taking into consideration of origins and destinations (ODs) distributions and route selection behaviours (e.g., shortest paths), we propose an extended betweenness centrality to investigate the traffic flow in two scenarios 1) the interior roads of Danwei and Xiaoqu are excluded from urban road network, 2) the interior roads are integrated into road network. A Danwei and a Xiaoqu in Shanghai are used as the study area. The preliminary results show the feasibility of our extended betweenness centrality in investigating the traffic flow patterns and reveal the quantitative changes of the traffic flow after opening interior roads.

The Impact

The purpose of this research is to address the impact of traffic networks on the supply-demand balance of tourism and to determine if it is necessary to incorporate the traffic flow data for nodes to determine the significant influences and impacts of traffic networks on tourism. For this purpose, a road network was established for Jiangsu province, and the topological parameters of this network and the tourism degree of coordination among each prefectural city were calculated as well. The results demonstrate that the inclusion of the spatial structure of the traffic network was not necessary for determining the supply-demand balance for tourism; thus, the collection of traffic flow data is required to perform further research. As a side result, it has been determined that the circuit routes are relatively absent from the Jiangsu traffic network, which might hinder tourism, and tourism resources are undersupplied to most prefectural cities in Jiangsu.

The Impact

The lack of a systematic definition of intermittency in the power sector blurs the use of this term in the public debate: the same power source can be described as stable or intermittent, depending on the standpoint of the authors. This work tackles a quantitative definition of intermittency adapted to the power sector, linked to the nature of the source, and not to the current state of the energy mix or the production predictive capacity. A quantitative indicator is devised, discussed and graphically depicted. A case study is illustrated by the analysis of the 2018 production data in France and then developed further to evaluate the impact of two methods often considered to reduce intermittency: aggregation and complementarity between wind and solar productions.

Ustadz Evie Effendi was a public figure who is known by the public as a modern ustadz that use the Sundanese language when do Da’wah. The perceptions given by the society particularly of ustadz Evie Effendi Da'wah pilgrims are positive until ultimately ustadz Evie exposed "misinterpretation" case in August 2018 when he misinterpreted a verse in the Sura in the Quran. The occurrence of a case of "misinterpretation" had a significant impact for ustadz Evie Effendi, one of them is a lot of pilgrims from ustadz Evie Effendi in Bandung which is no longer a loyal following lectures activities conducted by him. The existence of the impact that occurs from the "misinterpretation" case encourages researchers to see how the changes in perception that occurred in ustadz Evie Effendi Da'wah worshipers in Bandung. This study used a qualitative approach through the case study method uses the concept of Yin (2015). The results of this research show that changes in perception that occurred in Ustadz Evie Effendi Da'wah worshipers in Bandung is different for adult ages (40 – 50 years) and adolescents (20 years) as well as temporary caused culture society Indonesia which is permissive.Ustadz Evie Effendi merupakan seorang publik figur yang dikenal oleh masyarakat sebagai ustadz kekinian yang menggunakan bahasa Sunda ketika ceramah. Persepsi yang diberikan masyarakat khususnya jamaah dakwah ustadz Evie Effendi positif sampai pada akhirnya ustadz Evie terkena kasus “salah tafsir” pada bulan Agustus 2018 ketika ia salah menfasirkan ayat dalam suatu surat di Al-Quran. Terjadinya kasus “salah tafsir” memberikan dampak yang cukup besar bagi ustadz Evie Effendi salah satunya adalah banyak dari jamaah dakwah ustadz Evie Effendi di Kota Bandung yang tidak lagi setia mengikuti kegiatan ceramah yang dilakukan ustadz Evie Effendi. Adanya dampak yang terjadi dari kasus “salah tafsir” mendorong peneliti untuk melihat bagaimana perubahan persepsi yang terjadi pada jamaah dakwah ustadz Evie Effendi di Kota Bandung. Penelitian ini menggunakan pendekatan kualitatif melalui metode studi kasus menggunakan konsep Yin (2015). Hasil penelitian ini menunjukkan bahwa perubahan persepsi yang terjadi pada jamaah dakwah ustadz Evie Effendi di Kota Bandung berbeda untuk kalangan usia dewasa (40 – 50 tahun) dan remaja (20 tahun) serta bersifat sementara yang disebabkan kultur masyarakat Indonesia yang permisif.

Previous research has shown that cutbacks in public spending often impact the range and quality of the public services delivered, leading to negative behaviors on the part of public servants. This article examines how sudden cutbacks caused by a major state financial crisis have an impact on interpersonal trust within a special police unit. We present the results of a longitudinal case study using a combination of qualitative methods. The lack of foreseeability and reliability caused by drastic changes resulting from cutbacks has a negative effect on members’ trust in their capacity to perform.

Additional opinions—that is, dissenting opinions, separate opinions, and declarations—are, by definition, the primary institutional mechanism through which judges can express their individual views on a particular decision, as distinct from the judgment or decision proclaimed on behalf of the institution. Therefore, within the public sphere they are the principal institutional manifestation of the individual—and thus the individuality—of the judge. Consequently, for those who seek to understand the impact of certain personal characteristics upon how a judge discharges their professional functions and, in turn, the wider institutional and systemic implications of the participation of individuals bearing those characteristics, the study of additional opinions would seem a useful analytical enterprise. Using gender diversity at the International Court of Justice as a case study, the purpose of this chapter is twofold: first, to explain the relationship between diversity and additional opinions, and second, to explore the methodological potential, and challenges, that the study of additional opinions entails.

Based on a case study in Rennes, the article presents how a group of urban public actors re-uses methods and technology from citizen sciences to raise the urban air quality issue in the public debate. The project gives a group of inhabitants the opportunity to follow air quality training and proceed PM2.5µm measurements. The authors question the impact of the ongoing hybridisation between citizen science and urban public action on participants' commitment. The authors present how the use of PM2.5-sensors during 11 weeks led to a disengagement phenomenon, even if the authors observe a strong participation to workshops. These results come from an interdisciplinary methodology using observations, interviews, and data analyses.

Planar Networks

The street network is an important aspect of cities and contains crucial information about their organization and evolution. Characterizing and comparing various street networks could then be helpful for a better understanding of the mechanisms governing the formation and evolution of these systems. Their characterization is however not easy: there are no simple tools to classify planar networks and most of the measures developed for complex networks are not useful when space is relevant. Here, we describe recent efforts in this direction and new methods adapted to spatial networks. We will first discuss measures based on the structure of shortest paths, among which the betweenness centrality. In particular for time-evolving road networks, we will show that the spatial distribution of the betweenness centrality is able to reveal the impact of important structural transformations. Shortest paths are however not the only relevant ones. In particular, they can be very different from those with the smallest number of turns—the simplest paths. The statistical comparison of the lengths of the shortest and simplest paths provides a nontrivial and nonlocal information about the spatial organization of planar graphs. We define the simplicity index as the average ratio of these lengths and the simplicity profile characterizes the simplicity at different scales. Measuring these quantities on artificial (roads, highways, railways) and natural networks (leaves, insect wings) show that there are fundamental differences—probably related to their different function—in the organization of urban and biological systems: there is a clear hierarchy of the lengths of straight lines in biological cases, but they are randomly distributed in urban systems. The paths are however not enough to fully characterize the spatial pattern of planar networks such as streets and roads. Another promising direction is to analyze the statistics of blocks of the planar network. More precisely, we can use the conditional probability distribution of the shape factor of blocks with a given area, and define what could constitute the fingerprint of a city. These fingerprints can then serve as a basis for a classification of cities based on their street patterns. This method applied on more than 130 cities in the world leads to four broad families of cities characterized by different abundances of blocks of a certain area and shape. This classification will be helpful for identifying dominant mechanisms governing the formation and evolution of street patterns.

The Impact

COVID-19 could affect the global and local economy mainly by directly affecting production, by creation of disruption in supply chains and markets, as well as through its financial impact on firms and markets and organizations. However, the extent to which the impact is felt depends a great deal on the how governments and the public react to the disease. Here, a model is proposed to investigate the effect of the spread of corona virus infection and the consequent measures taken in response to its spread to lessen its impacts on the society and the economy. The interaction between the number of infected individuals and the variations in the national Growth Product, GDP, is modeled by a system of impulsive non-linear difference equations with delays. We are specifically interested in how different lock down measures effect business recovery as reflected by the national GDP. The model is analyzed to obtain valuable insights as to the factors that could yield different successes in the pandemic control and business recovery in various scenarios. Based on data of newly infected cases and cumulative cases weekly in Thailand, the model is simulated in a variety of scenarios to illustrate how different strategies and lockdown measures may give rise to different recovery rates.
