Drawing on the literature on entrepreneurship and competitive dynamics, we investigate how technological overlap between spinouts and parent firms influences corporate investors’ decisions regarding investments in spinouts. We suggest that a high level of technological overlap between a spinout and its parent firm deters potential corporate investors from making an investment in the spinout because of competitive tension arising from anticipated hostile actions by the parent firm. We further sug

Using a unique dataset on U.S. publicly listed firms that experienced sudden deaths of CEOs during the 1979–2002 period, this paper investigates the relationship between founder CEOs and innovation in public firms. Our main results show that the exogenous change from a founder CEO to a professional CEO is associated with a 41 percent decrease in a firm’s citation-weighted patent count, even when controlling for R&D expenditures, suggesting that founder CEOs are better managers of innovations tha

Abstract Research Summary We investigate why a corporate investor makes more corporate venture capital (CVC) investments in certain areas than in others. Focusing on firms' different technological capabilities across distinct technology domains, we argue that a corporate investor's technological capabilities in a given domain affect its likelihood of investing in (1) ventures within the domain in an inverted U‐shaped manner and (2) ventures operating in other technologically complementary domain

We investigate how the size of the geographic cluster in which a firm is located influences its governance choice between equity and non‐equity alliances and subsequent innovation performance. We argue that firms located in larger clusters tend to form non‐equity alliances rather than equity alliances because the communication and control benefits of cluster membership, which increase with cluster size, reduce in‐cluster firms' need to form equity alliances. We also claim that the effect of this

As machine learning (ML) became more relevant to our lives, ML education for college students without technical background arose important. However, not many educational games designed to suit challenges they experience exist. We introduce an educational game Classy Trash Monster (CTM), designed to better educate ML and data dependency to non-major students who learn ML for the first time. The player can easily learn to train a classification model and solve tasks by engaging in simple game acti

Prior studies on R&D alliances have assumed that technological complementarity is a subset of or a moderate level of technological similarity. This study suggests that technological similarity and complementarity are two distinct concepts and affect firms’ decision-making in R&D alliance formation differently. While firms conduct local searches to identify alliance partners that possess similar areas of technological knowledge, they also conduct relatively distant searches to identify al

Korean folk painting (minhwa) is built from a small vocabulary of auspicious symbols, a tiger for protection, a pair of birds for marital harmony, a peony for wealth, that recur across many of its painted genres. This suggests an obvious computational approach, identify which symbols appear in a painting and read the genre from the inventory. Working with a public corpus that pairs whole paintings, eight-field bilingual curatorial captions, and a separate set of expert object crops, we find that

The automated piano enables note densities, polyphony, and register changes far beyond human physical limits, yet the three dominant traditions for composing such textures--Nancarrow's tempo canons, Xenakis's stochastic distributions, and L-system grammars--have developed in isolation. This paper presents Amanous, a hardware-aware composition system for Yamaha Disklavier that unifies these methodologies through distribution-switching: L-system symbols select distinct distributional regimes rathe

Prior studies on R&D alliances have assumed that technological complementarity is a subset or a moderate of technological similarity. In this article, we argue that they are distinct concepts and affect firms’ decisions in R&D alliance formation with different mechanisms. We distinguish technological similarity and complementarity both theoretically and empirically and investigate their effects on the likelihood of R&D alliance formation between firms in the biopharmaceutical industry. We furthe

Piano fingering shapes how a passage can be played, yet it is difficult to label after a performance. An annotator must decide which finger produced each note while reconciling the score, timing, video, and hand motion. We present PiAnnotate, a web-based pipeline for adding expert fingering annotations to the FurElise performance dataset. The tool brings together a piano-roll view, performance video, and a 3D MANO hand mesh so that reviewers can inspect each assignment in musical and physical co

이 연구는 일본의 해양전략과 이를 구현하는 일본의 해군력, 즉 해상자위대 전력운용의 변화양상을 분석하였다. 이를 위해 냉전기와 탈냉전기, 그리고 미·중 패권경쟁기를 분석대상으로 하였다.냉전기 일본의 해양전략은 해상자위대가 미 해군과 연합하여 일본 주변해역에서의 제해권을 확보하여 일본 본토에 대한 해상으로의 침략을 억제 및 차단하는 것이었다. 이후 구소련의 대외팽창 정책이 가시화되면서 일본은「1,000해리 해상교통로 방위」와 「3해협 봉쇄」를 표명하고, 대잠전 능력 강화 및 해상방공체계 구축을 위해 해상자위대 호위함대 예하의 4개 호위대군을 8함 8기 체제로 편성하여 운용하였다.탈냉전기 일본의 해양전략은 해상자위대의 임무와 활동범위 확대라는 전략적 방향성을 보였다. 역내에서는 북한과 중국의 위협이 증대되고, 역외에서는 자위대의 역할 확대가 요구되는 상황에서 해상자위대의 임무와 활동범위가 확대되었다. 이에 따라 해상자위대는 원해작전능력 확보를 위해 콘고급 이지스함 4척 운용체제를 구축하
