How does the supervision effect affect the firm's performance in Taiwanese stock market?

This paper explores the impact of the CEO's supervisory role as an independent director on firm performance, utilizing measures such as Return on Equity (ROE) and Tobin's Q. The supervisory effect is assessed through the remuneration of directors and supervisors. Empirical findings indicate a significant supervisory role when the CEO also serves as an independent director.

Entrapment of horseradish peroxidase in sugar-modified silica monoliths: toward the development of a biocatalytic sensor.

A miniaturized HRP-entrapped bioreactor was prepared by a one-step enzyme immobilization method using a biocompatible sol-gel processing method employing either diglycerylsilane (DGS) or sodium silicate (SS) as precursors and a covalently tethered sugar, N-(3-triethoxysilylpropyl)gluconamide (GLS) as a silica modifier. Factors such as leaching, catalytic efficiency and long-term stability were examined to assess the role of the precursor and modifier in influencing enzyme performance. The results showed that sodium silicate derived materials modified with covalently bound sugars at a level of 10 mol% were optically transparent and provided the highest catalytic turnover rate for entrapped HRP.

Determination of volatile organic compounds in workplace air by multisorbent adsorption/thermal desorption-GC/MS.

Investigation of volatile organic compounds (VOCs) was first conducted in the air of class-100 cleanrooms at liquid crystal display (LCD) fabrication facilities. Air samples were collected on multisorbent tubes (including Carbopack B, Carbopack C, and Carbosieve S-III) and analyzed using adsorption/thermal desorption coupled with gas chromatography-mass spectrometry (GC-MS). Optimal conditions lead to average recoveries in the range of 96.
