    When two different odorants are presented simultaneously to the two nostrils, we experience alternations in olfactory percepts, a phenomenon called binaral rivalry. Little is known about the nature of such alternations. Here we investigate this issue by subjecting unstable and stable olfactory percepts to the influences of visual perceptual or semantic cues as participants engage in simultaneous samplings of either two different odorants (binaral) or a single odorant and water (mononaral), one to each nostril. We show that alternations of olfactory percepts in the binaral setting persist in the presence of visual perceptual and semantic modulations. We also show that perceptual cues have a stronger effect than semantic cues in the binaral case, whereas their effects are comparable in the mononaral setting. Our findings provide evidence that an inherent, stimulus-driven process underlies binaral rivalry despite its general susceptibility to top-down influences

    Nostril-Specific Olfactory Modulation of Visual Perception in Binocular Rivalry

    It is known that olfaction and vision can work in tandem to represent object identities. What is yet unclear is the stage of the sensory processing hierarchy at which the two types of inputs converge. Here we study this issue through a well established visual phenomenon termed binocular rivalry. We show that smelling an odor from one nostril significantly enhances the dominance time of the congruent visual image in the contralateral visual field, relative to that in the ipsilateral visual field. Moreover, such lateralization-based enhancement extends to category selective regions so that when two images of words and human body, respectively, are engaged in rivalry in the central visual field, smelling natural human body odor from the right nostril increases the dominance time of the body image compared with smelling it from the left nostril. Semantic congruency alone failed to produce this effect in a similar setting. These results, taking advantage of the anatomical and functional lateralizations in the olfactory and visual systems, highlight the functional dissociation of the two nostrils and provide strong evidence for an object-based early convergence of olfactory and visual inputs in sensory representations

    A dual cloud point extraction (dCPE) off-line enrichment procedure coupled with a hydrodynamic-electrokinetic two-step injection online enrichment technique was successfully developed for simultaneous preconcentration of trace phenolic estrogens (hexestrol, dienestrol, and diethylstilbestrol) in water samples followed by micellar electrokinetic chromatography (MEKC) analysis. Several parameters affecting the extraction and online injection conditions were optimized. Under optimal dCPE-two-step injection-MEKC conditions, detection limits of 7.9-8.9 ng/mL and good linearity in the range from 0.05 to 5 mu g/mL with correlation coefficients R (2) a parts per thousand yenaEuro parts per thousand 0.9990 were achieved. Satisfactory recoveries ranging from 83 to 108 % were obtained with lake and tap water spiked at 0.1 and 0.5 mu g/mL, respectively, with relative standard deviations (n = 6) of 1.3-3.1 %. This method was demonstrated to be convenient, rapid, cost-effective, and environmentally benign, and could be used as an alternative to existing methods for analyzing trace residues of phenolic estrogens in water samples.A dual cloud point extraction (dCPE) off-line enrichment procedure coupled with a hydrodynamic-electrokinetic two-step injection online enrichment technique was successfully developed for simultaneous preconcentration of trace phenolic estrogens (hexestrol, dienestrol, and diethylstilbestrol) in water samples followed by micellar electrokinetic chromatography (MEKC) analysis.

    Taiwan is located in the Circum-Pacific Seismic Zone; therefore, this island nation is destined to encounter recurrent cataclysmic earthquakes as what has been witnessed in the previous centuries. Taipei City, which is recognized as the most populous and densest city of Taiwan, has a series of push factors which lead herself standing with massive quakes. Besides, with old buildings, disordered urban pattern and lack of open space not only makes the city expose in an extremely dangerous situation but an uncomfortable living environment. Based on the descriptions above, the research objective of this thesis is focused on the following main question: “What are the landscape interventions that can create a safe and livable city?” As a result, in this thesis, it is mainly developed into two layers, emergency and living quality layers, and then combine them as a complete landscape design in Taipei for a safer and better living quality environment.Flowscapes StudioArchitecture, Urbanism and Building Sciences | Landscape Architectur

    To Redefine, Not Reinforce: A Spatial Decision Support System with Generative Design Model for Exploring Optimal Improvements to Existing Street Networks for Enhancing Equity of Accessibility

    Transport decision-making determines people’s level of accessibility and deeply influences an individual’s access to social and economic opportunities and the quality of life. Socially vulnerable populations are highly dependent on yet often more likely to have less access to transport services and experience lower accessibility. This creates and reinforces social and spatial inequalities by trapping people in disconnected neighborhoods and segregated areas that continue to be deprived of access to opportunities. This research aims to develop a Spatial Decision Support System (SDSS) to explore how re-purposing existing streets for walking and biking could influence the accessibility of vulnerable neighborhoods to support decision-making in enhancing equity of accessibility. In the SDSS, equity of accessibility is formulated as a generative design (GD) problem, named the Street Allocation Decision Problem (SADP), a single-objective optimization problem that searches for generated designs with the maximum weighted improvement in accessibility per unit of its cost. A GD model is built to solve SADP. Lastly, an operational framework is developed to guide prospective users in tuning and operating the SDSS for their specific context, problem, and objective. The SDSS is tested on a toy problem, a 0.09km2 area in The Hague, The Netherlands. The toy problem is small in scale, easy and fast to implement and useful for initial testing of the model. Preliminary results have demonstrated the feasibility of the model. This is the first and humble attempt at developing an SDSS for enhancing equity of accessibility with a GD model. However, there are shortcomings in methodology and result quality, which compromise the practicality of the model and the interpretability of results. Although, only a proof of concept at the moment, the SDSS is a valuable starting point due to its advantages, such as transparency, modularity, humane-ness, and flexibility. This SDSS is built to involve decision-makers in the design process, which could serve as a useful learning experience for questioning and understanding what is the problem, what is considered equitable, and what are possible solutions. The SDSS has the potential to facilitate learning during transport decision-making in experimental settings or as explorative aids in early design stages.Industrial Ecolog

    [[abstract]]This research aimed to explore the present situation and the consideration of the lesbians to participate in sports, their identity, their volition to come out and the willingness to participate in sport.. Data collected through the use of a specially designed paper and internet questionnaire of 282 lesbians, and in depth interviews from 11 of them, were analyzed by means of descriptive statistics, one-way ANOVA, F-test, scheffe, Pearson's correlation, and stepwise regression, and concluded from the results of the contents of the statistic data and the interview : 1. The sports environment in Taiwan was considerably friendly to lesbians, and lesbians were rather active in sports fields. The salary per month, record of normal schooling, sports skill level, and frequency of sports-taking of these lesbians is sports were also comparably higher than females and other lesbians in Taiwan in general. Lesbians of different sex belongings present life styles in great variety in sports. 2. Two major factors of the lesbians participating in sports were "sports demands" and "identity and activity of the lesbian ". They thought participation in sports had a positive influence on their identity of the lesbians. They had the most willingness to come out in sports gatherings, however, had the least willingness to come out in usual sports occasions. 3. This study confirmed the positive correlations among the consideration to participate in sports, identity, and the occasions to come out. These three factors also affect the willingness and behaviors of the lesbians to participate in sports. The most predictive factors of the willingness of the lesbians to participate in sports were "sports demands", "identity and activity of lesbians", "social identity", and "the situation for the lesbians to come out in sports gatherings".
