The use of medicinal plants as natural antimicrobial agents is gaining popularity. Sorrel (Hibiscus sabdariffa) is widely used for the treatment of diseases. The objective of this study was to investigate the antimicrobial activity of sorrel on Escherichia coli O157:H7 isolates from food, veterinary, and clinical samples. Phenolics of the calyces were extracted from 10 g of ground, freeze-dried samples using 100 mL of 80% aqueous methanol. Concentrations of 10%, 5%, and 2.5% methanol extract of sorrel were investigated for its antimicrobial activity. Inhibition zones were indicated by a lack of microbial growth due to inhibitory concentrations of sorrel diffused into semisolid culture medium beneath the sorrel-impregnated disk. The results of this experiment showed that the most potent sorrel concentration was 10%, then 5%, and finally 2.5%. The overall mean zone of inhibition for the sorrel extract was 12.66 mm for 10%, 10.75 mm for 5%, and 8.9 mm for 2.5%. The highest inhibition zones (11.16 mm) were observed in veterinary samples, and the lowest (10.57 mm) in the food samples. There were significant (P<.05) differences among mean zones of inhibition found in the food, veterinary, and clinical sources. Based on the source of samples and concentration of sorrel extract, the lowest mean inhibition was 7.00±0.04 mm from clinical samples, and the highest was 15.37±0.61 mm from a food source. These findings indicated that sorrel was effective at all levels in inhibiting E. coli O157:H7; thus it possesses antimicrobial activity and hold great promise as an antimicrobial agent.

Environmental Investment and Policy with Distortionary Taxes and Endogenous Growth
Don Fullerton,Seung-Rae Kim 한국재정학회(구 한국재정·공공경제학회) 2006 한국재정학회 학술대회 논문집 Vol.2006 No.2
Recent studies consider public R&D spending that affects abatement knowledge and endogenous growth, distortionary taxes that affect physical and human capital formation, pollution taxes that affect environmental degradation, and regeneration that restores natural capital. Our model combines all of those elements. We show how the combination affects results from each prior model, focusing on two parameters that represent the need for distorting taxes, and the productivity of abatement knowledge relative to pollution. First, either of these two extensions can reverse the prior finding that pollution tax revenue is more than enough to pay for public abatement R&D. Second, tax distortions and externalities substantially alter prior findings that the ratio of public to private capital is based only on output elasticities. Third, our dynamic model affects prior static findings about how other public spending “crowds out” provision of the environmental public good. Fourth, we show whether a greater need for public spending leads to greater increases in the distorting tax or pollution tax. Fifth, while prior research is optimistic that environmental regulation can boost economic growth, we show how it may increase or decrease the growth rate – even if it raises welfare.

Identifying the conceivable diplomatic outcomes of Sport Diplomacy initiatives
Abdi Kambiz,Fullerton Jami,Deheshti Mohammad,Kavand Reza,Monibi Hamidreza,Talebpour Mahdi 한국외국어대학교 국제지역연구센터 2022 International Area Studies Review Vol.25 No.4
Although studies around Sport Diplomacy (SD) are expanding rapidly, there is no specific agreement on the outcomes of SD initiatives. The purpose of this study is to identify the conceivable diplomatic outcomes of SD from the perspective of international public diplomacy and sport experts. Researchers used a fuzzy Delphi method, which is an advanced version of the qualitative Delphi method that employs statistics to determine the distance between the levels of consensus within the expert panel. Thirty online surveys were completed by the experts, who were selected through targeted sampling. The statistical population included public diplomacy and sports scholars, and the researchers identified about 200 individuals who qualified for the sampling population because of their academic studies in the fields of public, cultural, and sport diplomacy. After running two rounds of fuzzy Delphi, the SD outcomes were classified into two categories of explicit/specific outcomes and implicit/general outcomes. The results showed that the outcomes of “cross-cultural communication,” “mutual understanding,” “trust building,” “nation branding,” “country reputation,” “attraction,” and “co-option” were the most possible explicit/specific outcomes of SD initiatives undertaken by countries’ ministries of foreign affairs and related agencies. “Sport industry development,” “sport tourism development,” and “socio-economic development” were the most possible outcomes of the implicit/general efforts of SD initiatives undertaken by the sport federations, private sector, NGOs, and other institutions outside the formal diplomacy system. Co-option-A term derived from Nye's theory of soft power as the ultimate goal/outcome of SD endeavors is manifested in “Peace Building (Conflict Conciliation)” between hostile states/nations and “Peace Development” between friendly states/nations.

This study explores an intricacy between cultural character and consumer ethics. The study investigates the South Korean public’s perceptions of a set of 12 scenarios describing ethically questionable consumer actions. The scenarios include illegal actions such as fraudulently inflating one’s losses when filing an insurance claim and legal, but questionable actions such as showrooming. The 12 scenarios exhibited a wide range of mean responses, supporting the commonly-stated premise that consumer ethics is situational in nature. Furthermore, the results document a relationship between the acceptance of ethically questionable behaviors and the extent of monetary loss incurred by the victimized organization.

Converting sports diplomacy to diplomatic outcomes: Introducing a sports diplomacy model
Kambiz Abdi,Mahdi Talebpour,Jami Fullerton,Mohammad Javad Ranjkesh,Hadi Jabbari Nooghabi 한국외국어대학교 국제지역연구센터 2018 International Area Studies Review Vol.21 No.4
As sport has become an integral part of society, it has also become a tool for diplomacy around the world. The purpose of this study is to introduce a sports diplomacy model and identify “the critical abilities” for converting sport soft power tools into resources for diplomatic outcomes. The data for this research comprise 30 online surveys completed by international experts in the fields of sports and public diplomacy. The responses were qualitatively analyzed using the fuzzy Delphi method (FDM). After running two rounds of fuzzy Delphi, two main strategies for sports diplomacy emerged—maintaining “official and sports diplomacy solidarity” and using sport figures as “competent cultural ambassadors.” The proposed model includes the most applicable sports diplomacy resources, the most expected diplomatic outcomes, and the major conversion tools (skillful strategies) in the viewpoint of sports and public diplomacy experts. The application of the model finds that states can expect diplomatic outcomes if appropriate sports diplomacy resources and conversion strategies are implemented in an orderly, innovative and accurate manner.

<P>Building upon the success and relevance of the 2014 Magnetism Roadmap, this 2017 Magnetism Roadmap edition follows a similar general layout, even if its focus is naturally shifted, and a different group of experts and, thus, viewpoints are being collected and presented. More importantly, key developments have changed the research landscape in very relevant ways, so that a novel view onto some of the most crucial developments is warranted, and thus, this 2017 Magnetism Roadmap article is a timely endeavour. The change in landscape is hereby not exclusively scientific, but also reflects the magnetism related industrial application portfolio. Specifically, Hard Disk Drive technology, which still dominates digital storage and will continue to do so for many years, if not decades, has now limited its footprint in the scientific and research community, whereas significantly growing interest in magnetism and magnetic materials in relation to energy applications is noticeable, and other technological fields are emerging as well. Also, more and more work is occurring in which complex topologies of magnetically ordered states are being explored, hereby aiming at a technological utilization of the very theoretical concepts that were recognised by the 2016 Nobel Prize in Physics.</P> <P>Given this somewhat shifted scenario, it seemed appropriate to select topics for this Roadmap article that represent the three core pillars of magnetism, namely magnetic materials, magnetic phenomena and associated characterization techniques, as well as applications of magnetism. While many of the contributions in this Roadmap have clearly overlapping relevance in all three fields, their relative focus is mostly associated to one of the three pillars. In this way, the interconnecting roles of having suitable magnetic materials, understanding (and being able to characterize) the underlying physics of their behaviour and utilizing them for applications and devices is well illustrated, thus giving an accurate snapshot of the world of magnetism in 2017.</P> <P>The article consists of 14 sections, each written by an expert in the field and addressing a specific subject on two pages. Evidently, the depth at which each contribution can describe the subject matter is limited and a full review of their statuses, advances, challenges and perspectives cannot be fully accomplished. Also, magnetism, as a vibrant research field, is too diverse, so that a number of areas will not be adequately represented here, leaving space for further Roadmap editions in the future. However, this 2017 Magnetism Roadmap article can provide a frame that will enable the reader to judge where each subject and magnetism research field stands overall today and which directions it might take in the foreseeable future.</P> <P>The first material focused pillar of the 2017 Magnetism Roadmap contains five articles, which address the questions of atomic scale confinement, 2D, curved and topological magnetic materials, as well as materials exhibiting unconventional magnetic phase transitions. The second pillar also has five contributions, which are devoted to advances in magnetic characterization, magneto-optics and magneto-plasmonics, ultrafast magnetization dynamics and magnonic transport. The final and application focused pillar has four contributions, which present non-volatile memory technology, antiferromagnetic spintronics, as well as magnet technology for energy and bio-related applications. As a whole, the 2017 Magnetism Roadmap article, just as with its 2014 predecessor, is intended to act as a reference point and guideline for emerging research directions in modern magnetism.</P>
