Abstract:
Innovative Design Thinking (IDT) is a systematic design framework for product development. In this talk, the conceptual design framework of IDT will be introduced. The framework includes concept generation phase and concept improvement phase. In concept generation, there are three steps- formation, organization, and selection. In concept improvement, it suggests an approach integrating sequencing and modularization methods. IDT guides innovators to design and develop innovative product and its family and ensures the product is logically-feasible, functionally-simple, and physically-certain in an ideal as well as practical way.

Abstract:
For next-generation integrated circuits, photonics may take over electronics to provide fast-speed, low-loss devices. Among all potential materials, Silicon is one of the best candidates owing to its natural abundance and well-established fabrication technique.

The foundation of silicon electronics lies in the nonlinear response from pn junctions, so similar to that, the key element in silicon photonics is optical nonlinearity. However, the optical nonlinearity of silicon is not particularly large. There have been various methods to enhance silicon’s nonlinear response, including microring resonator and photonic crystal, both based on light confinement. In addition, it is also well known that photothermal effect provides the largest third-order nonlinearity in general.

In this work, we show that by amalgamating light confinement based on nanostructure engineering and photothermal effect, seven-order enhancement of nonlinear coefficient over bulk silicon is demonstrated, with mode volume. The experimental nonlinearity from scattering measurement agrees well with photothermal simulation. The exceptionally large nonlinearity not only enables all-optical control with large modulation depth and small footprint, but also paves the way towards integrated silicon nanophotonic circuits.

請注意：本週演講時間調整至週日 (US) / 週一 (TW)
01/13 (Sun.) 6 pm PST, 7 pm MST, 8 pm CST, 9 pm EST
01/14 (Mon.) 10 am Taiwan

Keywords:
Criminology and Criminal Justice, Corrections, Rehabilitation, Re-entry, Correction Programming, Punitive Attitude

Abstract:

The primary purpose of this research is to examine different Ban the Box legislation in six states. This research uses a systematic literature review with three significant components as examination strategy. This presentation mainly focuses on the criminal record system and Ban the Box policy in the US. In the beginning, the presenter will introduce the production of criminal records and the impacts of incarceration, particularly in the labor market. Next, a brief historical background regarding Ban the Box campaign will be introduced. Finally, a detailed examination of the six states’ Ban the Box laws will be presented. Relevant policy implications will be discussed as well.

本研究的主要目的是檢視六個州的 Ban the Box 法律，該研究使用系統性文獻分析搭配三個重要的分析策略。本次演講主要聚焦在美國的犯罪紀錄系統與 Ban the Box 政策。講者將會介紹犯罪紀錄的產出過程，監禁對於就業市場所造成的影響，Ban the Box 社會運動的歷史背景，以及對於六個 Ban the Box 州法的檢視結果。相關的政策建議也會一併被討論。
