Protic Ionic Liquid as Reagent, Catalyst, and Solvent: 1‐Methylimidazolium Thiocyanate

AbstractWe propose a new concept of the triple role of protic ionic liquids with nucleophilic anions: a) a regenerable solvent, b) a Brønsted acid inducing diverse transformations via general acid catalysis, and c) a source of a nucleophile. The efficiency of this strategy was demonstrated using thiocyanate‐based protic ionic liquids for the ring‐opening of donor‐acceptor cyclopropanes. A wide variety of activated cyclopropanes were found to react with 1‐methylimidazolium thiocyanate under mild metal‐free conditions via unusual nitrogen attack of the ambident thiocyanate ion on the electrophilic center of the three‐membered ring affording pyrrolidine‐2‐thiones bearing donor and acceptor substituents at the C(5) and C(3) atoms, respectively, in a single time‐efficient step. The ability of 1‐methylimidazolium thiocyanate to serve as a triplex reagent was exemplarily illustrated by (4+2)‐annulation with 1‐acyl‐2‐(2‐hydroxyphenyl)cyclopropane, epoxide ring‐opening and other organic transformations.

The Role of Value Co-Creation in ICT-based Service Innovation within Tourism Context

The rapid development of technology has shifted the conventional tourism industry towards the digitalization of the tourism sector. The emergence of travel booking platforms, as a form of technology-based service innovation, is able to simplify traveling activities and previous works of literature have indicated a positive relationship towards customer satisfaction. However, tourist’s behavior has change become more demanding to involve in the creation of value in accordance with their needs and wants. The concept of value co-creation elaborates this issue, offering a new concept of value creation and new roles between service providers and tourists. This study aims to examine value co-creation as mediating variable between IT-based service innovation and customer satisfaction, using DART measurements and SEM-PLS is used to assess the model. The findings prove that IT-based service innovation positively influences value co-creation between users, which can increase customer satisfaction. However, IT-based service innovation does not have a direct impact on customer satisfaction, which indicates that value co-creation fully mediating the relationship between service innovation and customer satisfaction. Thus to enhance customer satisfaction, service providers need to propose service innovation that facilitates customer involvement in value creation, which can be supported by technology. Keywords: Customer satisfaction, Service innovation, Tourism, Travel booking platform, Value co-creation.

The cyber-work performance of managers in education

PurposeThis study addresses the perspective of N = 273 school principals as related to technology role in performing managerial roles.Design/methodology/approachIn the context of this study, the concept of technology only refers to digital office tools such as microcomputers, email and administrative software. The concept of managerial roles is understood and used herein in relation to the definition provided by Mintzberg (2013) in his managerial typology. Moreover, a survey method was used to collect data from the aforementioned managerial employees. The managerial typology of Mintzberg was applied as a theoretical lens to collect and interpret survey data.FindingsThe findings suggest that surveyed school principals believe that technology use improves their ability to perform informational and decisional roles at work. Arguably, these managerial employees are satisfied with using technology as a labor tool for administrative and managerial work.Research limitations/implicationsThis study is limited because its sample size does not allow the findings to be generalized to all Canadian school principals. Nevertheless, the findings are significant because they suggest that similar to the positive technology-related attitude of managerial employees in business organizations, those in school organizations also perceive technology as an organizational asset. For that reason, management scholars should not only limit their studies of the intersection between technology and managerial roles or work to business organizations. They also need to extend their research studies and fieldwork to school organizations.Originality/valueThe originality of this study lies in the fact that in management literature, the intersection between technology and the managerial roles of school principals is underresearched. As such, this study represents a step forward toward the need to study the technology-related behaviors of school principals to better understand how technology use enables their workflow system.

Women's Liberation in Meiji Japan: Ruptures in Cultural Conceptions of Female Education, Social Roles, and Political Rights

In 1872, the Meiji government issued the Education Act aiming to provide basic public education for boys and girls. The clash between Confucian ideals of women and the recently introduced Western literature on female liberation divided opinions among scholars. Having been influenced by the writings of British thinkers such as John Stuart Mill or Herbert Spencer, Japanese male and female thinkers proceeded to enlist various arguments in favor of female schooling and equal rights. Despite their advocating the right of women to attend schools, as well as their general agreement regarding the favorable results that girls’ education could bring to the nation, it is possible to identify key differences among scholars concerning the content of girls’ education and the nature of women’s rights. This paper focuses on Kishida Toshiko, an important female figure in Meiji politics who fought not only for female education but emerged at the forefront of activism in her advocacy of women’s political rights and universal suffrage, showing the clear influence of British suffragette Millicent Garret Fawcett.

Factors Affecting Brand Relationship Quality of Halal Food and The Mediating Role of Halal Literacy

Purpose: Brand relationship is anemerging phenomenon and companies are giving it a lot of importance. Islamic marketing is gaining grounds everywhere in the world and capturing a lot of attention in the countries where Muslims are in majority and even in minority. Present research aims to evaluate factors like brand experience, religiosity, price and role of halal literacy as a mediator to the brand relationship quality of halal food brands. Methodology: Survey research method has been conducted in Kuching and Kota Samarahan cities of Sarawak State, Malaysia. 270 respondents took part in this research. The partial least square method (PLS-SEM) has been used for data analysis. Findings: The findings of the research suggest that experiential value, price, and religiosity have effect on brand relationship quality of halal food brands. The role of halal literacy as a mediator has been found significant in respect of experiential value and religiosity, while it remained unchanged in determining the price. Research Limitation: The research has been conducted by applying cross sectional data method. The study is limited to the state of Sarawak, Malaysia and it concerns only the food products. Practical Implication: The findings of this research can be considered as a help by brand managers in formulating their marketing and business strategy. Originality/Value: This research endeavoured to explore the importance of religiosity in customer-brand relationship of halal food brands. Moreover, the concept of the mediation role of price transparency has been investigated for the first time. It indicates that this area has never been explored before in research.

Myosteatosis in NAFLD patients correlates with plasma Cathepsin D.

Previously, we have shown that hepatic lipid accumulation induces the secretion of cathepsin D (CTSD), and that plasma CTSD levels are associated with increased inflammation and disease severity in nonalcoholic fatty liver disease (NAFLD). Although it is clear that the liver is a major source of plasma CTSD, it is unknown whether other metabolically active organs such as the muscle, also associate with plasma CTSD levels in NAFLD patients. Therefore, the aim of this study was to explore the relation between lipid accumulation in the muscle (myosteatosis) and plasma CTSD levels in forty-five NAFLD patients. We observed that hepatic steatosis positively associated with plasma CTSD levels, confirming the previously established link between plasma CTSD and the liver. Furthermore, a positive association between myosteatosis and plasma CTSD levels was observed, which was independent of sex, age, BMI, waist circumference and hepatic steatosis. By establishing a positive association between myosteatosis and plasma CTSD levels, our findings suggest that, in addition to the liver, the muscle is also linked to plasma CTSD levels in NAFLD patients. The observed link between myosteatosis and plasma CTSD levels supports the concept of a significant role of the skeletal muscle in metabolic disturbances in metabolic syndrome-related disorders.

The first part discusses the theoretical background of the problem in the literature of the subject: the definitions of volunteering, sources of motivation, legal issues and qualifications and competences to the concept of volunteer role. The next part presents and discusses the results of our own research focused on the forms of volunteering carried out by students of special pedagogy.

Olfactory receptor Olfr78 (prostate-specific G protein-coupled receptor PSGR) expression in arterioles supplying skeletal and cardiac muscles and in arterioles feeding some murine organs

The olfactory receptor Olfr78 (prostate-specific G protein-coupled receptor PSGR) is a member of the G protein-coupled receptor family mediating olfactory chemosensation, but it is additionally expressed in other tissues. Olfr78 expressed in kidney participates in blood pressure regulation, and in prostate it plays a role in the development of cancer. We here screened many organs/tissues of transgenic mice co-expressing β-galactosidase with Olfr78. X-gal-positive cells were detectable in smooth muscle cells of numerous arterioles of striated muscles (heart ventricles and skeletal muscles of various embryological origin). In addition, in most organs where we found expression of Olfr78 mRNA, X-gal staining was restricted to smooth muscle cells of small blood vessels. The dominant expression of Olfr78 in arteriolar smooth muscle cells supports the concept of an important role in blood pressure regulation and suggests a participation in the fine tuning of blood supply especially of striated muscles. This should be considered when targeting Olfr78 in other contexts such as prostate cancer.

Imitation as a social norm that influences the choice of career and labor participation of women

In Latin America, labor market indicators still show large gender gaps in access to opportunities and rights. These inequalities persist despite various policy efforts because they emanate from a social system that reproduces stereotypes and gender roles. This contradicts the development vision of the United Nations and the ILO: “Without gender equality, sustainable development is neither development nor sustainable”. This contribution focuses on the impact of social norms on women's decisions, regarding career choice and labor participation. To this end, we have built and simulated an agent-based model. The model assumes that gender roles are acquired and reproduced through the environment that surrounds women. The results of this social simulation suggest that the environment greatly influences the perception of women about the roles they must assume and the areas in which they must play, so it is pertinent to design policies aiming to change the conceptions of identity and traditional gender roles, since the construction and adoption of new and more equitable values is in part acquired through the imitation of the behavior observed in a woman's environment.

The Linguistic Creation of a City in the 16th-century Polish Accounts from Travels to the Holy Land

The article tries to describe the linguistic creation of a city in Polish 16th-century diaries from journeys to the Holy Land. During long trips, the authors visited many exotic, for the Polish traveller, cities and towns to whom they devoted a lot of space in their diaries. The analysis is based on findings of theory of linguistic image of a world and on the concept of linguistic creation and semiotic role. The author outlines the set of linguistic means used by the diarists to indicate various roles. He concludes that the image of a city presented in the analysed texts oscillates between traditional frame that has its source in the classical antiquity and modern perspective significant for the man of the Renaissance.

Історіософські концепти Русі і їх роль у синтезі сучасної національної ідеї сучасної України

Кризові явища всередині України, значною мірою випливають з відсутності об’єднуючої, ціннісної, світоглядної моделі яка б спрямувала існуючі ідеологічні вектори в одному, конструктивному для нації напрямку. Вирішення цієї проблеми можливе засобами філософського дослідження оскільки підвалини національної ідеї ґрунтуються на метафізичних ідеях і цінностях, що не можуть бути охоплені методами емпіричних наук. Автор аналізує концепти Київської Русі, які можуть виконати об’єднавчу роль у синтезі нової національної ідеї для українців. Серед них розглянуто концепт «Святої Русі», норманського походження державності Русі і концепт її посередницької ролі між Цивілізаціями Сходу, країнами Заходу і Скандинавії. Автором показано перспективи застосування цих концептів у сучасних умовах.

The Lasting Impact of a First Impression: An Exercise for the First Day of Class

This article details an exercise for the first day of class in an introductory sociology course. Students in two sections of Introduction to Sociology taught by the same professor and covering the same content, with the exception of the exercise on the first day of class, were surveyed at the end of the semester regarding the first day. Student responses in the section with the experiment reveal that students believe that the activity is useful in making them think deeper, recalling and applying sociological concepts to their own lives, and challenging their conceptions of roles of students and professors in the college classroom. These students also report positive recollections of the first day and of the professor. Additionally, the future trajectory of students in each section (in terms of their decision to major, minor, or take further classes in sociology) reveals surprisingly different paths.

COMMUNICATIVE ROLE OF A JUDGE: STRATEGIES AND TACTICS OF SPEECH BEHAVIOR IN JUDICIAL DISCOURSE

The article is devoted to the review of scientific concepts of judicial discourse as a kind of legal discourse, analyzes the main communicative roles of a judge in judicial discourse, clarifies the main strategies and tactics of speech behavior characteristic of the communicative role of a judge in judicial discourse. The concept of communicative role is thoroughly characterized by such a scientist as J. Sternin, who divides the communicative role into standard and initiative, and initiative, in turn, is also divided into two groups: short-term (short-term, situational) and long-term (long-term). The main views of modern linguists on the problem of defining judicial discourse are reviewed, in particular, the linguistic aspects of communication in court are thoroughlypresented. The degree of research of the problem in linguistics on studying the problems of legal discourse is analyzed, for example the works of such scientists as N. V. Artykutsa, S. V. Dordy, Yu. F. Pradid, O. L. Dotsenko, O. O. Kobzeva are presented.The focus is on the problem of legal terminology, various aspects of the language of legislation, linguistic issues of legal expertise and features of speech genres of legal discourse.

Algumas considerações em torno ao imbroglio Posada: quando as imagens não ilustram os textos

A impressionante obra gráfica do gravurista mexicano José Guadalupe Posada (1852-1913) – dentro da qual se destacam as famosas calaveras alegres e dançantes – tem chamado a atenção de estudiosos há décadas. Umas das questões mais controversas nesses estudos diz respeito às relações do artista com a política, sendo que existe uma espécie de imbroglio envolvendo, de um lado, a visão de um Posada revolucionário e precursor da Revolução Mexicana e, de outro, a imagem de um Posada reacionário e porfirista. O objetivo deste trabalho é matizar essas duas versões dicotômicas e propor um novo olhar sobre as relações da obra de Posada com o universo político de sua época partindo da análise de algumas de suas gravuras publicadas na imprensa popular mexicana, principalmente a partir do acirramento da oposição à ditadura de Porfirio Díaz até as últimas obras do artista, falecido em 1913. A análise toma como base a proposta de Guillermo Sunkel (2016 [1985]) sobre as “matrizes culturais” e as concepções de Mikhail Bakhtin (1993 [1965]) a respeito do papel subversivo do “riso popular”. 

Indigenous Health Workforce: exploring how roles impact experiences in Higher Education

Indigenous people have an integral role to play in improving Indigenous health outcomes by leading and being a part of the health workforce. Educating Indigenous health professionals is hence of great importance. Indigenous health students are not always acknowledged for their multiple professional and community roles and how these can affect their university education experience and success. This paper hence examines the experiences of 27 Indigenous health students and their lecturers at one Australian university around the concept of roles. The study used an Indigenous Research Methodology combined with theory driven thematic analysis. Results identified both positive and negative experiences of roles that significantly affect Indigenous health students. The study showed that students’ roles in family and community are complex and can come into conflict with student and future professional roles when students attend university. Academics interviewed for the research showed little to no understanding of Indigenous students’ complex existing roles. This research may assist universities and educators to support Indigenous health students to transition from community to university and achieve success.

A Negotiative Theory of Journalistic Roles

Abstract In probing how journalists negotiate the perceived discrepancy between their social role orientation and role performance, we arrive at a negotiative theory of roles. The theory is based on an inductive study where we combine classic theoretical frameworks of role theory with conceptual approaches of discursive institutionalism and Hochschilds’ theory of feeling rules. We examined journalists’ narratives from qualitative in-depth interviews with 20 Swiss newspaper journalists, who were asked to interpret the perceived gap—found in previous studies—between journalism ideals and journalism practice. The results compelled us to revisit role theories and to consider a number of overlooked or under-utilized analytic features of social roles to propose refinements to the concepts of journalistic roles and role performance. This resulted in a negotiative theory of roles that focuses attention on intra- and interpersonal discourse as well as what we call “role work.”

Uterine Sandwich Suture: The Concept of “Role Sharing” Is Important

Uterine compression suture and intrauterine hemostatic balloon are important procedures to achieve hemostasis for obstetric hemorrhage. A combined use of these two, with B-Lynch suture + Bakri balloon being the most often employed ones, is referred to as a “uterine sandwich”, which is an effective hemostatic procedure. Fundamentally, the former and latter stop bleeding from the uterine body and lower uterine segment, respectively. This represents the concept of “role sharing” for hemostasis. Recognizing this concept is of practical importance.

A flexible fine-grained dynamic access control approach for cloud computing environment

As a pioneering surge of ICT technologies, offering computing resources on-demand, the exceptional evolution of Cloud computing has not gone unnoticed by the IT world. At the same time, security stands as a most prior concern for this new progressive computing capability of on-demand services over the Internet. Hence, access control substantiates one of the fundamental conditions to fortify the information and Cloud system against illegitimate access among all the security requirements of Cloud computing. Although diverse access control models have been proposed and implemented for the Cloud computing paradigm, the models may fail to accomplish the dynamic and scalable requirements of the Cloud system adequately. Therefore, we propose a dynamic authorization system for a Cloud computing environment that employs the concept of role, task, and trustworthiness of the user. In this paper, a framework has been proposed that offers characteristics of both passive and active access control along with the trusted computing, thereby, blending the model into a more fine-grained and dynamic for the Cloud computing environment. Subsequently, the implementation of the propounded scheme is reported to provide the proof-of-concept. Additionally, the evaluation and use case scenario of the propounded system has been carried out to proclaim its effectiveness over other conventional models.
