Electric field aligned growth of single-walled carbon nanotubes
캠벨,J.Svensson,S. Dittmer 한국물리학회 2004 Current Applied Physics Vol.4 No.6
Electric eld aligned, single-walled carbon nanotubes are grown between electrodes using thermal chemical vapour deposition(CVD) of methane. The growth occurs on a thin lm layered catalyst of aluminium, iron and molybdenum patterned on top of electrodes. The nanotubes bridge 10l m sized electrode gaps and have a typical diameter of less than 2 nm as measured by Ramanspectroscopy and atomic force microscopy. We present electrical transport measurements on a directly grown nanotube whichshows p-type semiconducting behaviour.
Public Participation and Trust in Government: Results From a Vignette Experiment
제시 캠벨 서울대학교행정대학원 2023 The Korean Journal of Policy Studies Vol.38 No.2
Securing the trust of citizens can facilitate the delivery of high-quality public services and government has a duty to act in a trustworthy manner. However, even if public service quality is high and policy sound, if decisions are made without accountability, trust in government may suffer. Public participation can contribute to the legitimacy of the exercise of government power. Using a two-by-two vignette-based experiment embedded in a survey conducted in South Korea, I test the impact on trust in government of public participation in the policymaking process under conditions of both good and poor policy performance. The results suggest that participatory policymaking marginally increases citizen trust in government. However, they also suggest that performance is the critical factor, and that participation alone cannot reverse the trust-damaging effect of poor performance. Although this research has limitations, it also has practical implications for public managers considering involving the public in the policymaking process, particularly when the costs of doing so are non-trivial.
From Social Control to Social Instability
Colin Campbell(콜린 캠벨) 한국라틴아메리카학회 2010 라틴아메리카연구 Vol.23 No.3
This article examines the evolving nature of the 'war on drugs' and its connections to US-Mexican bilateral security relations, seeking to enable the reader to understand the socio-political context of the on-going war on drugs in Mexico. The article discusses the changing nature of the US and Mexican responses to the 'war' as vested interests of the respective elite classes evolve. This is particularly evident in post-1980s Mexico, as the ruling PRI lost its grip on the reigns of power both at local and state level in the North of the country to the PAN (Partido Accion Nacional). It was during this period that the flow of narcotics, notably cocaine increased via Mexico into its North American neighbour. This combined with an increased readiness by drug cartels to use violence both amongst themselves and against agents of the Mexican state. As a result, from the 1980s to the present day, the level of violence experienced in the North of the country has steadily increased as its ties to the corporate model implemented by the PRI are severed and Mexico moves towards a more democratic model of governance. However, the states failure to provide a dominant reason d'etat and implement law and order has led to increased level of violence, which has moved from the northern border region and now is present throughout the country. Having previously been reliant on the Mexican military to abate the problem, the Mexican state is struggling to contain the threat posed by the drug cartels.
