The smooth-to-rough colony morphology shift in Mycobacterium abscessus has been implicated in loss of glycopeptidolipid (GPL), increased pathogenicity, and clinical decline in cystic fibrosis (CF) patients. However, the evolutionary phenotypic and genetic changes remain obscure. Serial isolates from nine non-CF patients with persistent M. abscessus infection were characterized by colony morphology, lipid profile via thin-layer chromatography and matrix-assisted laser desorption ionization-time o

The community is one of the key concepts recently rising in the field of local regeneration in Korea. It is also related to a big paradigm shift the Korean local development has experienced over the past decade. In the new paradigm, local communities play a key role as a main body leading the efforts and as an energy source powering development. This paper aims to examine the changed circumstances that require the paradigm shift in local regeneration policies, and to suggest a normative model of

ABSTRACT This paper expands the literature on agglomeration economies in three ways. It disentangles amenity and productivity effects of agglomeration; it decomposes aggregate scale effects into agglomeration factors of interest to policy makers; and it estimates own effects and spillovers to neighbors. It proposes a spatial simultaneous equations model in a spatial equilibrium framework with three agents—workers, consumers, and producers of traded-goods and housing. Results for Ohio counties es

As the Chinese economy grows, Chinese people’s environmental behavior enormously affects the environment of neighboring countries as well as China. Many studies have related environmental behavior to personal characteristics such as environmental knowledge and attitude or to national policies such as environmental taxes and regulations. Few studies have looked at how regional factors affect residents’ environmental behaviors, particularly for China. This is a substantive gap in the literature re

Community gardens (CGs) are gaining popularity as an alternative use for vacant lots in communities that struggle to address the negative effects of property abandonment. A pressing issue for these communities is to determine which vacant lots are most appropriate for community gardening. Therefore, this study aimed to identify the determinants of vacant lot conversion into CGs. We looked at existing CGs and vacant lots in the City of Philadelphia and identified CGs converted from vacant lots. A

It is well acknowledged that agglomeration economies contribute to knowledge production, which is crucial in the current knowledge-based economy. The literature on evolutionary agglomeration stresses that the effects of agglomeration economies may vary depending on the industry life cycle. But much is not known about what sources of agglomeration economies play an important role in knowledge production at each stage of the life cycle: industrial localization versus diversification, and leadershi

A way to simulate circuits associated with power electronics and perform HIL (Hardware In the Loop) controller testing by the simulation using a real time digital simulator is described in this paper. The benefit of using a real time simulation environment for such testing is explained. The demonstration of HIL capability of the real time simulation with an external controller is illustrated in this paper as well. The simulation results as well as certain observations such as time delay between

This study expands on the literature of residential abandonment by considering five types of industrial and commercial properties and three levels of explanatory variables – parcel, neighbourhood, and city. Using data for Cleveland, Ohio, it shows that tax policies have a limited impact on abandonment. Instead, two categories of variables not previously modelled are significant and policy relevant. First, the more specialised a property and the greater the cost of conversion to alternative uses,

근래 들어 발생한 용산참사와 마을공동체 만들기 사업은 서울의 시민사회를 둘러싼 권력관계의 양면성을 보여준다. 한편에서는 국가-시민사회의 관계가 억압-저항의 관계로, 다른 한편에서는 협력-참여의 관계로 완전히 상반되게 나타난다. 이연구는 이러한 양면성의 근원을 찾기 위해 지난 20여 년간 변화해온 시민사회의저항과 대안의 공간 및 운동의 변화를 국가-시장-시민사회 삼각관계라는 틀을 이용하여 분석한다. 특히 우리는 민주주의의 확대와 신자유주의의 확산이라는 모순적 계기가 한국의 국가-시장-시민사회의 관계의 변화를 규정해왔고, 이러한 모순적 계기가 시민사회를 둘러싼 권력관계의 양면성을 초래하고 있음을 규명한다. 그리고 국가의 기회주의적 행태, 서울의 도시사회운동의 제도화, 지방정치체제의보수와 진보 사이에서의 동요, 참여적·저항적 운동방식의 공존 등의 현상은 이러한 모순적 계기의 산물임을 밝혀낸다. 이러한 발견들로부터 우리는 서울시민의운동에 대한 실천적 의미를 도출한다.

The recent emergence of the “urban commons” is associated with the “exclusion” problems of modern cities, which are enmeshed in the mechanism that spatially excludes those who are incapable of paying the market prices. Cities are also tightly regulated by various government regulations that control people’s actions, and creative practices are often stifled. The excluded not only resist commercialization, privatization, and state laws but also crave and pursue their own space and lifestyle. This

This study derives the economic development effects of sanctuary city (SC) policies at the US county level using data from close to 3,000 counties between 2013 and 2017. A county is taken to provide sanctuary to undocumented immigrants if county jails do not accept ICE detainer requests, i.e. do not hold detainees beyond their original release dates. Endogeneity problems and fixed effects in the panel data are fully accounted for by combining coarsened exact matching with the fixed effects instr

This paper presents a method to interconnect and synchronize two instances of real time simulation. A Bergeron transmission line model is utilized as interface between two simulation instances. Communication to transfer the necessary transmission line model quantities is implemented by utilizing TCP/IP socket communication. Part of the real time simulator includes the hardware communication facility. In regards to the necessary synchronization, an external precision clock source is used at the b
