To overcome this issue, we designed an experiment in which EEG’s temporal dynamics and spatial information are evaluated together to improve the performance of brain-computer interface (BCI) for classifying finger movement directions. Six volunteers participated in the study. We examined their EEG using decoding analyses. Independent components (ICs) that represented brain-source signals successfully classified the directions of the finger movements with higher rates than chance level. The weight analyses of the classifiers revealed that maximal performance of the classification was recorded at the latencies prior to the onset of finger movements. The weight analyses also revealed the relevant cortical areas including the right lingual, left posterior cingulate, left inferior temporal gyrus, and right precuneus, which indicated the involvement of the visuospatial processing. We concluded that combining spatial distribution and temporal dynamics of the scalp EEG may improve BCI performance.</span>展开更多

The death of Hung Chung-Chiu, along with a series of events, including the Referendum of Lungmen Nuclear Power Plant and Dapu Incident, triggered the White Shirt Movement led by Citizen 1985. The movement, as the local harbinger of Internet-organized demonstration, performed a novel form of citizen activity, teasing out a protesting guerrilla that tactically networked disempowered and dispossessed subjects. The guerrilla utilized local mediascapes in reacting to official force with its flowing tactics, which signify the ceaseless negotiation, battle, and play between government and citizens. Extending Sue-Ellen Case＇s notion of horizontal practice of politics and the performative, this paper focuses on the various theatrical elements used in its activities, including environmental theater and social networking, in order to delineate the traumatic imaginaries and flowing tactics embodied by the White Shirt Movement. Working within and against one another, imaginaries and tactics travel back and forth between physical and virtual spaces, constituting the mobility and structure of contemporary protest events.展开更多

More than 50% of these spoonbills winter regularly on the southwestern coast of Taiwan. From 2007 to 2019, the rate of increase of the Black-faced Spoonbill population was only 10.5%, which is lower than the rate of 12.0% per year reported between 1991 and 2004. Black-faced Spoonbills have experienced several bottlenecks, and problems may exist in their breeding and/or in wintering habitats. Understanding the ecological environment of their habitats in Taiwan is an important issue, including the current use of water birds, the water depth of their habitats and even the aquatic plants. A total population of 93,614 birds of 88 species was recorded in a survey of the Cigu salt pan from October 2017 to October 2018. The biodiversity H' (loge) of the total birds was 2.67. Dunlin (Calidris alpina) was the most dominant species with a population of 21,053 (22.5%), followed by Kentish Plover (Charadrius alexandrinus) with a population of 20,350 (21.7%). The largest area of terrain elevation at -1.0 to -0.2 m was 685.4 ha (38.5%) and at -0.2 to -0.1 m was 320.4 ha (18.0%). Between 2017 and 2018, the similarity in water depth classification was 47.2%, reflecting climate change, a degree of water accumulation, and the wader utilization situation. A strategy for maintaining biodiversity in the Cigu salt pan wetland and conserving spoonbills is therefore proposed in this paper.展开更多
