Unique Amino Acid

Silk fibroin is a widely and commercially available natural protein derived from silkworm cocoons. Thanks to its unique amino acid composition and structure, which lead to localized nanoscale pockets with limited but sufficient hydration for protein interaction and stabilization, silk fibroin has been studied in the field of enzyme immobilization. Results of these studies have demonstrated that silk fibroin offers an important platform for covalent and noncovalent immobilization of enzymes through serving as a stabilization matrix/support with high retention of the biological activity of the enzymes of interest. In the hope of providing suggestions for potential future research directions, this review has been written to briefly introduce and summarize key advances in silk fibroin-based materials for immobilization of both enzymes/biocatalysts (including alkaline phosphatase, β-glucosidase, glucose oxidase, lipase, urease, uricase, horseradish peroxidase, catalase, xanthine oxidase, tyrosinase, acetylcholinesterase, neutral protease, α-chymotrypsin, amylase, organophosphorus hydrolase, β-galactosidase, carbonic anhydrase, laccase, zymolyase, phenylalanine ammonia-lyase, thymidine kinase, and several others) and non-enzymatic catalysts (such as Au, Pd, Fe, α-Fe2O3, Fe3O4, TiO2, Pt, ZnO, CuO, Cu2O, Mn3O4, and MnO2).

Scholarly Attention

Management from Islamic Perspectives (MIP) is an emerging field that has begun to attract scholarly attention. However, the research undertaken so far has been rather fragmented and lack a clear agenda. This paper presents a literature review of the field and the areas of current focus. Although the field has a huge growth potential, I argue that it faces several challenges and problems as it develops further. I outline these potential pitfalls, suggest how to develop MIP as a formal discipline, and explain how to integrate it within real-life business practices. The article closes with a call for research to be conducted in a more organized fashion through an international consortium of researchers as well as recommendations for future research directions.

With the growth of cannabis tourism, destinations such as the Netherlands have begun to offer cannabis-related products and services to visitors, including tourists from countries where all drugs are strictly prohibited. Yet limited research has sought to understand cannabis-oriented tourists' efforts to neutralize deviant connotations, namely by justifying or rationalizing misbehavior, when deciding to participate in cannabis tourism. This research note proposes a framework of deviant consumption behavior (DCB) constructed of geographic shifting, self-identity shifting, and moral identity shifting from the perspective of cannabis-oriented tourists to delineate tourists' decision-making process around engaging in deviant behaviors. The proposed framework suggests that previously developed DCB frameworks in the marketing and consumer behavior literature should be adapted for use in outbound tourism research. This research note also highlights areas for debate and investigation regarding cannabis tourists' deviant behavior. Future research directions are provided based on the proposed framework as it applies to deviant tourism research.
