Role of Spillover in the Repeated Interaction Model of Tax Competition

2005-05This paper generalizes the model of Cardarelli et al. (Journal of Public Economic Theory, 2002, 4(1), 19-38) by adding the benefit spillover of local public goods. Traditional public finance literature suggests that a benefit spillover is ‘harmful’ since it causes the choices of local governments to be inefficient from the viewpoint of society as a whole. This paper, however, shows that the spillovers can act as a beneficial factor in achieving an efficient outcome.departmental bulletin pape

Analysis of learners' states and stumbling blocks using biometric information in Scratch programming learning

プログラミング教育の必修化に伴い，ビジュアルプログラミング言語であるScratchを用いたプログラミング授業の導入が広がっている．しかし，教育現場では教員の人数が不足しているため，学習者全員の状態を把握した指導が容易ではない．そこで本研究では，教員の指導を支援するため，生態情報を活用することで，学習者の状態と躓きの関係を明らかにする．具体的には，集中力および手の動きに着目し，測定および分析を行なう．With the introduction of compulsory programming education, the introduction of programming classes using Scratch, a visual programming language, is spreading. However, due to the shortage of teachers in the field, it is not easy to provide instruction that grasps the state of all learners. In this study, we clarify the relationship between learners' states and stumbling blocks by using ecological information to support teachers' instruction. Specifically, we will measure and analyze concentration and hand movements.application/pdfdepartmental bulletin pape

Positive effects of virtual window into worker's personal space

執務者の生産性や集中力の向上のためには，個人スペースが重要な役割を果たすとされている． しかし，個人スペースは壁や仕切りによって閉塞感が生じる． そこで，本論文では，個人スペースに擬似窓を導入することの有効性を検証する． 実験結果より，擬似窓に適切な映像を映写することで，窓の効用を得るだけでなく，WELL認証に良い影響を与えることがわかった．Improving the productivity and concentration of workers, it is reported that personal space plays an important role. However, a worker feels confined in many cases, as walls and partitions usually surround these areas. In this paper, we verify the effectiveness of introducing the Virtual Window into personal space. From the experimental results, it was found that projecting an appropriate image on the Virtual Window not only obtains the utility of the window but also has positive effects on WELL authentication for office workers.application/pdfdepartmental bulletin pape

BINOL-Catalyzed Highly Enantioselective Terminal Alkyne Additions to Aromatic Aldehydes

The readily available BINOL ligand in combination with Ti(OiPr)4 was found to catalyze the highly enantioselective reaction (92−98% ee) of terminal alkynes with aromatic aldehydes that contain a variety of substituents and substitution patterns. After the preparation of the zinc acetylide reagent, the catalytic asymmetric addition to aldehydes proceeded at room temperature with excellent stereocontrol. This simple catalyst system is practical for the asymmetric synthesis of chiral propargylic alcohols

Simultaneous Printing of Two Inks by Contact Lithography

Microcontact printing (μCP) is a valuable technique used to fabricate complex patterns on surfaces for applications such as sensors, cell seeding, self-assembled monolayers of proteins and nanoparticles, and micromachining. The process is very precise but is typically confined to depositing a single type of ink per print, which limits the complexity of using multifunctionality patterns. Here we describe a process by which two inks are printed concomitantly in a single operation to create an alternating pattern of hydrophobic and hydrophilic characteristics. The hydrophobic ink, PDMS, is deposited by evaporation on the noncontact region, while the hydrophilic polyelectrolyte is transferred on contact. We demonstrate that there is no gap between the two patterns using an optical–electrochemical method. We describe some potential applications of this method, including layer-by-layer deposition of polyelectrolytes for sensors and creation of a scaffold for cell culture
