A rational path towards a Pareto optimum for reforms of large state-owned enterprise in China, past, present and future

Since Deng Xiaoping’s historic move towards a market economy in post-Mao China during the 1980s, by far, the most challenging task in China’s reforms has been that related to the moribund state-owned sector due to a range of ideological, political, as well as economic reasons. Such reforms have so far been slow and hesitant, moving forward and backward with mixed results. This paper tackles the pros and cons of such reforms and aims to square a rational strategy based on what has been done so far in the state sector. Unlike a narrow approach currently prevailing in the literature, this paper establishes a partial equilibrium model which incorporates the principal-agent problem into a mixed oligopoly model to explore an optimal strategy for state-owned enterprise reforms in China. We argue that ceteris paribus the current illnesses of low efficiency and rent-seeking commonly suffered by China’s state-owned sector can be cured by a two-pronged strategy in which the importance of property rights holds the key. We have identified two ‘Coase Property Right Points’ in the commonly known choices of institutional changes in a reforming Soviet economy to firstly, make it more efficient, and then Pareto optimal. One institutional change is a ‘joint-stock reform’; the other, a ‘full privatisation reform’. In particular, this study regards ‘social-extra policy burdens’ as the main obstacle to improve much needed efficiency in the state sector. Coase Property Right Points show the necessity for a reduction of the social-extra policy burdens vis-à-vis the state sector’s true comparative advantag

Performance and mechanisms of the Maoist economy: a holistic approach, 1950-1980

This article probes performance and mechanisms of the Maoist economy from 1950 to 1980, a period commonly regarded as a turning point that ushered in a bumpy but new path for China’s new economic fortune, including industrialisation and modernisation. Mao and his government have often been regarded as a developer and moderniser for China. This study questions it. To that end, the Maoist economy is re-conceptualised, re-examined, and re-assessed with qualitative and quantitative evidence including empirical modelling. The key findings suggest that the Maoist economy was a closed one with industrial dependence on agriculture in an urbanrural zero-sum. In the end, despite the official propaganda agriculture declined, industrial workforce stagnated, and the population was poor. This gloomy performance justified the post-Mao reforms and opening up, a game changer that put China on a very different trajectory of growth and development

Using iPads in the Reading Room

In 2010, Boise State University began integrating mobile technology into teaching and learning environments on campus. Albertsons Library Special Collections and Archives (ALSCA) at the university soon followed; as an experiment in November 2012, we gave patrons access to four iPads in our reading room. We asked researchers to use them and share their experiences. Although the iPads were available for only six weeks, we quickly realized the benefits of making iPads a permanent addition to our reading room

Walk This Way: The Effects of Wearing a Knee Brace on Gait

Gait is defined as the way a person walks; the manner of his or her steps taken. Walking is a simple concept that can be taken for granted until it is lost. When a movement in the gait cycle is limited due to injury, changes in biomechanical and neurological factors occur. The purpose of this study was to measure and evaluate gait patterns of subjects walking with and without a Breg T Scope Premier Post-Op Knee Brace. Twenty-two Texas Lutheran University students were tested using the Dartfish Software program in the Kieffer Laboratory. Seven females and fifteen males, ranging in ages 18 to 28 years, completed two five meter walks. The first recording was of the subjects walking without the Post-Op Knee Brace and the second recording was of the subjects walking with the Post-Op knee brace. The knee brace was set to limit the subject twenty degrees of full knee extension, not allowing full range of motion. Each subject was recorded from the front view and from the side view; the videos were then analyzed through Dartfish Software. Eight reflective markers were applied to the subject prior to walking to distinguish boney landmarks for angle measurement. Using a Paired Two Sample t-Test, a significant difference was found for hip flexion and extension, hip abduction, dorsiflexion, and plantar flexion. Hip Flexion, hip extension, plantar flexion, and dorsiflexion decreased with the addition on the Post-Op Knee Brace and hip abduction increased, resulting in gait abnormalities

A connected autonomous vehicle testbed: Capabilities, experimental processes and lessons learned

VENTURER was one of the first three UK government funded research and innovation projects on Connected Autonomous Vehicles (CAVs) and was conducted predominantly in the South West region of the country. A series of increasingly complex scenarios conducted in an urban setting were used to: (i) evaluate the technology created as a part of the project; (ii) systematically assess participant responses to CAVs and; (iii) inform the development of potential insurance models and legal frameworks. Developing this understanding contributed key steps towards facilitating the deployment of CAVs on UK roads. This paper aims to describe the VENTURER Project trials, their objectives and detail some of the key technologies used. Importantly we aim to introduce some informative challenges that were overcame and the subsequent project and technological lessons learned in a hope to help others plan and execute future CAV research. The project successfully integrated several technologies crucial to CAV development. These included, a Decision Making System using behaviour trees to make high level decisions; A pilot-control system to smoothly and comfortably turn plans into throttle and steering actuation; Sensing and perception systems to make sense of raw sensor data; Inter-CAV Wireless communication capable of demonstrating vehicle-to-vehicle communication of potential hazards. The closely coupled technology integration, testing and participant-focused trial schedule led to a greatly improved understanding of the engineering and societal barriers that CAV development faces. From a behavioural standpoint the importance of reliability and repeatability far outweighs a need for novel trajectories, while the sensor-to-perception capabilities are critical, the process of verification and validation is extremely time consuming. Additionally, the added capabilities that can be leveraged from inter-CAV communications shows the potential for improved road safety that could result. Importantly, to effectively conduct human factors experiments in the CAV sector under consistent and repeatable conditions, one needs to define a scripted and stable set of scenarios that uses reliable equipment and a controllable environmental setting. This requirement can often be at odds with making significant technology developments, and if both are part of a project’s goals then they may need to be separated from each other

Investigating the Nature of and Methods for Managing Metroplex Operations

A combination of traffic demand growth, Next Generation Air Transportation System (NextGen) technologies and operational concepts, and increased utilization of regional airports is expected to increase the occurrence and severity of coupling between operations at proximate airports. These metroplex phenomena constrain the efficiency and/or capacity of airport operations and, in NextGen, have the potential to reduce safety and prevent environmental benefits. Without understanding the nature of metroplexes and developing solutions that provide efficient coordination of operations between closely-spaced airports, the use of NextGen technologies and distribution of demand to regional airports may provide little increase in the overall metroplex capacity. However, the characteristics and control of metroplex operations have not received significant study. This project advanced the state of knowledge about metroplexes by completing three objectives: 1. developed a foundational understand of the nature of metroplexes; 2. provided a framework for discussing metroplexes; 3. suggested and studied an approach for optimally managing metroplexes that is consistent with other NextGen concept

From state resource allocation to a 'low-level equilibrium trap': re-evaluation of economic performance of Mao's China, 1949-78

This paper provides a full picture of how Maoist economy actually performed. We argue that Mao’s China neither undertook a structural change towards industrialisation nor generated a sustainable growth from 1949 to 1978.2 With fatal shortcomings of a planned economic system imported from the Soviet Union – the ‘principle-agent’ problem and information asymmetry for the bureaucracy, and disincentives for producers – China’s economy remained not only deliberately unbalanced but also predominantly rural until the 1980s. More importantly, the Maoist economy was not designed to enrich and empower the masses in society. Instead, all key consumer goods including food, clothing and housing were strictly rationed. The material life of ordinary citizens in China saw no improvement. This paper aims to reveal the harsh reality of the Maoist economy with solid evidence and theoretical explanation

A Critical Appraisal of the UK’s Regulatory Regime for Combustible Façades

The Grenfell Tower fire has brought the regulatory system that permitted combustible materials on high-rise buildings in England into question. At the heart of that system is the BS 8414 test, and the BR 135 criteria used to demonstrate compliance with the Building Regulations. The test is empirical and the criteria arbitrary: there is no scientific link between test performance and how a building will perform in the event of a fire; nor any detailed analysis of why fires spread through façade systems which have passed the test. Following the Grenfell tragedy, the UK government commissioned a series of tests on Grenfell Tower-type facades, using BS 8414. This paper critically analyses BS 8414, the BR 135 criteria and the government tests. It shows that important aspects of the standard are poorly defined: the heat flux imposed on the façade is not measured and the fire load can vary by at least a factor of 2; the ambient ventilation has a significant impact on the thermal attack but is not adequately controlled; judicious location of the cavity barriers can confer compliance or failure on a façade system. As the vehicle for allowing combustible products on tall buildings, the test does not specify the extent of cavity barrier deployment, while ignoring features present in real buildings, such as windows, vents or other openings, despite a test rig height of more than 8 m. There is no restriction on debris, or molten or burning droplets falling from the façade during the test. The BR 135 criteria only specify that the test must run for the full 60 min duration without flames reaching the top, and the temperature rise at thermocouples 5 m above the fire chamber must only remain below 600°C for the first 15 min. It is unclear how the fire safety of the occupants behind the façade system can be ensured, when the criteria specify such a high temperature for such a short period, so early in the test. There is no direct connection between the façade system in the test and the actual façade system the results deem compliant. Worse, “desktop studies”, using large-scale test data, have been allowed to confer compliance on systems which have never been subject to the test. The UK government tests used heavy-duty welded aluminium “window pods”, preventing flames from entering the cavity within the façade. They also used a disproportionately large number of vertical and horizontal cavity barriers of a higher specification than required by statutory guidance. These aids to meeting the criteria are not proscribed by BS 8414-1 but are not commonly found in actual rainscreen system designs
