Analyzing the Effects of Car Sharing Services on the Reduction of Greenhouse Gas (GHG) Emissions
sustainability Article Analyzing the Effects of Car Sharing Services on the Reduction of Greenhouse Gas (GHG) Emissions Jiyeon Jung 1 and Yoonmo Koo 1,2,* 1 Technology Management, Economics and Policy Program, College of Engineering, Seoul National University, 1 Gwanak-ro, Gwanak-gu, Seoul 08826, Korea; [email protected] 2 Graduate School of Engineering Practice, Seoul National University, 1 Gwanak-ro, Gwanak-gu, Seoul 08826, Korea * Correspondence: [email protected]; Tel.: +82-2-880-2269 Received: 7 February 2018; Accepted: 9 February 2018; Published: 17 February 2018 Abstract: This study examines the environmental impacts of roundtrip car sharing services by investigating transportation behavior. Car sharing should contribute to reduced greenhouse gas GHG emissions; however, such schemes include both positive and negative environmental effects, including: (1) reduced CO2e (carbon dioxide equivalent) from substituting private vehicle use for more fuel-efficient car sharing vehicles, (2) increased CO2e as car-less individuals switch from public transit to car sharing vehicles and (3) reduced CO2e due to fewer vehicles. This study examines the impacts of this modal shift on greenhouse gas (GHG) emissions using three types of models: a mixed logit model to analyze car sharing service preferences; a binary logit model to analyze whether individuals are willing to forgo vehicle ownership or planned purchases to use car sharing services; and a linear regression to determine how much private vehicle or public transportation use would be replaced by car sharing and the resulting effects on mobility. Total emissions from the current car sharing market equal 1,025,589.36 t CO2e/year. -

The Foreign Office and Policy-Making in China 1945-1950
THE FOREIGN OFFICE AND POLICY-MAKING IN CHINA 1945-1950. ANGLO-AMERICAN RELATIONS AND THE RECOGNITION OF COMMUNIST CHINA. ROBERT EMMERSON WATSON ~- Submitted in accordance with the requirements for the degree of Ph.D. THE UNIVERSITY OF LEEDS INSTITUTE FOR INTERNATIONAL STUDIES MAY 1996 The candidate confirms that the work submitted is his own and that appropriate credit has been given where reference has been made to the work of others. 11 ABSTRACT. The thesis contributes to the broad body of literature which examines the role of Great Britain in the origins of the Cold War. In particular it focuses on the Foreign Office attitude towards the course of the Chinese Civil War, and ultimately the establishment of a Communist government in China between 1945 and 1950. It is a revisionist interpretation of cold war history drawn from a study of Anglo-American relations with regard to Chinese politics during this period. Traditional interpretations have emphasised the unchallenged nature of American involvement in China after the war. The thesis argues that during this period Britain actively sought to compete for such a predominant position, and specifically that the Foreign Office sought to replace the United States with Britain as the pre eminent Western influence in post-war Chinese politics. To this end, Britain gradually moved its policy from one of co operation with the United States to one of competition. Whilst originally seeking collaboration with Washington, the Foreign Office became increasingly frustrated with the problems within the American policy making machinery, and ultimately pursued a unilateral position in China. This was most evident after 1948 when the rapid collapse of the Kuomintang position forced Western states to closely consider their relationship with the Chinese communists. -

SHARED MOBILITY SYSTEMS GILBERT LAPORTE, FRED´ ERIC´ MEUNIER, AND ROBERTO WOLFLER CALVO Abstract. Shared mobility systems for bicycles and cars have grown in popularity in recent years and have attracted the attention of the operational research community. Researchers have investigated several problems arising at the strategic, tactical and operational levels. This survey paper classifies the relevant literature under five main headings: station location, fleet dimensioning, station inventory, rebalancing incentives, and vehicle repositioning. It closes with some open research questions. Key words: survey, shared mobility systems, bicycle and car sharing, fleet dimensioning, inventory rebalancing, vehicle repositioning. 1. Introduction The world of transportation has witnessed a mini-revolution in June 2007 with the launch- ing of the V´elib'bicycle sharing system in Paris. -
Testing Demand Responsive Shared Transport Services Via Agent-Based Simulations
TESTING DEMAND RESPONSIVE SHARED TRANSPORT SERVICES VIA AGENT-BASED SIMULATIONS Giuseppe Inturri, Nadia Giuffrida, Matteo Ignaccolo, Michela Le Pira, Alessandro Pluchino, Andrea Rapisarda University of Catania Abstract Demand Responsive Shared Transport (DRST) services take advantage of Information and Communication Technologies (ICT), to provide “on demand” transport services booking in real time a ride on a shared vehicle. In this paper, an agent-based model (ABM) is presented to test different the feasibility of different service configurations in a real context. First results show the impact of route choice strategy on the system performance. Keywords: shared mobility, flexible transit, dynamic ride sharing, demand responsive transport, agent-based model Introduction This paper focuses on the potential contribution of innovative Demand Re- sponsive Shared Transport (DRST) services provided by a fleet of vehicles, booked by users via mobile device applications and scheduled in real-time to pick up and drop off passengers in accordance with their needs [1]. The system stands between an expensive conventional exclusive-ride door-to-door service (like a conventional taxi) and a flexible system where a dynamic sharing of trips makes users experiment longer travel distances and times while the vehicles drop off and pick up other pas- sengers (like a conventional transit). From the operator’s point of view, it is important to select the optimal strat- egy to assign vehicles to passengers’ requests, so to perform high load factor and low driven distance (to reduce operation costs), while minimizing the additional time and distances travelers have to experience (to assure the expected level of ser- vice). -
An Analysis of the Factors Influencing the Sustainable Use Intention Of
sustainability Article An Analysis of the Factors Influencing the Sustainable Use Intention of Urban Shared Bicycles in China Peng Shao * and Jie Liang School of Management, Xi’an Polytechnic University, Xi’an 710048, China; [email protected] * Correspondence: [email protected]; Tel.: +86-137-0914-2830 Received: 5 April 2019; Accepted: 6 May 2019; Published: 14 May 2019 Abstract: Bicycle sharing services have played an active role in building a green travel system in China, but this trend has also caused problems, such as users arbitrarily stopping on the roads or the destruction of shared bicycles. Based on data collected by means of a survey that we designed, a regression analysis is used to test the influence of use perception and consumer characteristics on the intention to sustainably use shared bicycles by measuring the intention to: continue using the service, park the bicycles in an orderly manner, and care and protect the bicycles. We find that: (1) perceived usefulness, perceived ease of use, consumer innovation, and standardized use behavior have a significantly positive impact on the intention to continue using and park shared bicycles in an orderly manner; (2) perceived usefulness, perceived ease of use, and consumer innovation also have a significantly positive impact on the intention to care and protect shared bicycles; and, (3) standardized use behavior has no significant impact on the intention to care and protect shared bicycles. Moreover, urban air quality plays a positive regulatory role in the relationship of perceived usefulness, perceived ease of use, and consumer innovation with the intention to sustainably use the service. -

The evaluation results showed that the eastern region of China has the highest level of sustainable development, with its two municipalities directly under the central government, Beijing and Shanghai, achieving the full score of 1.0000 in all evaluations, both ranking first among all the provinces. There were significant differences in the level of sustainable development across provinces in the central region, which were comparatively weaker in terms of environmental sustainability and science and technology sustainability, with four provinces’ evaluation scores below 0.5000. -
US-China Strategic Competition in South and East China Seas
U.S.-China Strategic Competition in South and East China Seas: Background and Issues for Congress Updated September 8, 2021 Congressional Research Service https://crsreports.congress.gov R42784 U.S.-China Strategic Competition in South and East China Seas Summary Over the past several years, the South China Sea (SCS) has emerged as an arena of U.S.-China strategic competition. China’s actions in the SCS—including extensive island-building and base- construction activities at sites that it occupies in the Spratly Islands, as well as actions by its maritime forces to assert China’s claims against competing claims by regional neighbors such as the Philippines and Vietnam—have heightened concerns among U.S. observers that China is gaining effective control of the SCS, an area of strategic, political, and economic importance to the United States and its allies and partners. Actions by China’s maritime forces at the Japan- administered Senkaku Islands in the East China Sea (ECS) are another concern for U.S. observers. Chinese domination of China’s near-seas region—meaning the SCS and ECS, along with the Yellow Sea—could substantially affect U.S. strategic, political, and economic interests in the Indo-Pacific region and elsewhere. Potential general U.S. goals for U.S.-China strategic competition in the SCS and ECS include but are not necessarily limited to the following: fulfilling U.S. security commitments in the Western Pacific, including treaty commitments to Japan and the Philippines; maintaining and enhancing the U.S.-led security architecture in the Western Pacific, including U.S. -

Received: 22 June 2014; in revised form: 19 August 2014 / Accepted: 20 August 2014 / Published: 1 September 2014 Abstract: In the past 30 years, China’s economy has experienced rapid development, which led to a vast increase in energy consumption and serious environmental pollution. Among the different types of pollution, heavy metal pollution has become one of the major environmental issues in China. A number of studies show that high level of heavy metal exposure is a frequent cause of permanent intellectual and developmental disabilities. In recent years, some traditional pollutants, such as sulfur dioxide and carbon dioxide, have been put under control in China. However, heavy metal pollution, which poses even greater risks to public health and sustainable development, has yet to gain policymakers’ attention. The purpose of this paper is to explore effective countermeasures for heavy metal pollution in China. The present study reviews the current status of China’s heavy metal pollution and analyzes related public policies and countermeasures against that pollution.
