AbstractIn the field of scientometrics, the principal purpose for author co-citation analysis (ACA) is to map knowledge domains by quantifying the relationship between co-cited author pairs. However, traditional ACA has been criticized since its input is insufficiently informative by simply counting authors’ co-citation frequencies. To address this issue, this paper introduces a new method that reconstructs the raw co-citation matrices by regarding document unit counts and keywords of references, named as Document- and Keyword-Based Author Co-Citation Analysis (DKACA). Based on the traditional ACA, DKACA counted co-citation pairs by document units instead of authors from the global network perspective. Moreover, by incorporating the information of keywords from cited papers, DKACA captured their semantic similarity between co-cited papers. In the method validation part, we implemented network visualization and MDS measurement to evaluate the effectiveness of DKACA. Results suggest that the proposed DKACA method not only reveals more insights that are previously unknown but also improves the performance and accuracy of knowledge domain mapping, representing a new basis for further studies.

The implementation of todays forest management that based on formal-scientific knowledge and technical knowledge seems to fail to protect the forest from deforestation and the environmental damage. Decolonialisation of western knowledge could give an opportunity to identify and find the knowledge and practices of indigenous people in sustainable forest management. Forest management based on the indigenous knowledge and practices is believed easy to be accepted by the indigenous community due to the knowledge and practice is known and ‘lived’ by them. The Atoni Pah Meto from West Timor has their own customary law in forest management that is knows as Bunuk. In the installation of Bunuk, there is a concencus among the community members to protect and preserve the forest through the vow to the supreme one, the ruler of the earth and the ancestors, thus, bunuk is becoming a le’u (sacred). Thus, the Atoni Meto will not break the bunuk due to the secredness. Adapting the bunuk to the modern forest management in the Atoni Meto areas could be one of the best options in protecting and preserving the forest.

In the present day scenario prime need of Ayurveda is practical applicability of Ayurvedic fundamental principles and research should be more focused on all aspects where scientific inputs should confirm Ayurveda’s principles and philosophy. In Ayurveda, Gunas are described as the way of presentation of action without which no Karma (action) can be possible. Ayurveda has provided significance to every Guna so that they become useful in clinical practice. Clinical practice or research is a continuous process including a series of events which need to be performed in a sequential manner. Though there are many factors on which accomplishment of treatment depends, among these Charaka has given prime importance to Paradi Gunas. In clinical practice, Guna which are to be with Bhishak are mainly the Paradi Gunas which can also be called as miscellaneous Gunas. As rightly quoted by Acarya Charaka, for getting success in the treatment Paradi Gunas are the best. The Sutra quotes "Sidhyupaya Chikitsayam" which means that Chikitsa i.e. Dhatusamya will be done mainly with the help of Paradi Gunas. Knowledge of Paradi Gunas are required to be present in pharmacists, physicians and Researchers. Acharya Charaka says that Chikitsa Siddhi i.e. successful management of disease is not possible without the knowledge of Paradi Gunas. Paradi Gunas play an important role in selection, adaption and manifestation of drug as per condition of the disease and the patient in particular Desha and Kala. The ultimate goal of any clinical activity is to contribute in the knowledge domain and to improve professional practice. Thus this literary review of Paradi Gunas serves to explore the subject of the clinical practice.

Contrary to the conventional belief that social movements cannot engage the state without becoming co-opted and demobilized, this study shows how movements can advance their struggles by strategically working with, in, through, and outside of state institutions. The success of Brazil’s Landless Workers Movement (MST) in occupying land, winning land rights, and developing alternative economic enterprises for over a million landless workers has made it an inspiration for progressive organizations globally. The MST’s educational initiatives, which are less well known but equally as important, teach students about participatory democracy, collective work, agroecological farming, and other practices that support its socialist vision. This study details how MST activists have pressured municipalities, states, and the federal government to implement their educational proposal in public schools and universities, affecting hundreds of thousands of students. Based on twenty months of ethnographic fieldwork, Occupying Schools, Occupying Land documents the potentials, constraints, failures, and contradictions of the MST’s educational struggle. A major lesson is that participating in the contentious co-governance of public education can help movements recruit new activists, diversify their membership, increase practical and technical knowledge, and garner political power. Activists are most effective when combining disruption, persuasion, negotiation, and co-governance into their tactical repertoires. Through expansive leadership development, the MST implemented its educational program in local schools, even under conservative governments. Such gains demonstrate the potential of schools as sites for activists to prefigure, enact, and develop the social and economic practices they hope to use in the future.

The emergence of practice-centered computing (e.g., Computer-Supported Cooperative Work, or CSCW) raises the crucial question: How can we conceptualize the practices into which the prospective technology is to be integrated? How can we, reasonably, say of two observed activities or events that they are, or are not, instances of the same type? These are crucial questions. This chapter therefore attempts to clarify the concepts of “practice” and “technique.” First, since our ordinary concepts of “practice” and “technique” developed as part of the evolution of modern technology, as tools for practitioners’ and scholars’ reflections on the role of technical knowledge in work, the chapter outlines the major turning points in the evolution of these concepts, from Aristotle (via the scholastics), to enlightenment thinkers such as Diderot and Kant, and finally to Marx and Marxism. The chapter thereafter moves on to analyze the concepts as we use them today in ordinary discourse.

AbstractThis paper examines the multilingual translation efforts of a group of university student volunteers during the COVID-19 outbreak in Shanghai. Data were collected through semi-structured interviews of the volunteer team leader, team members, and a local community health worker. Findings identified time constraints, limited language proficiency, and limited technical knowledge as the major challenges confronting the university volunteers. In order to overcome the challenges, they worked in close collaboration and used translingual and network strategies to facilitate prompt and high-quality crisis translation. Findings suggest that foreign language university students in local universities may serve as readily available multilingual resources and can be mobilized in prompt response to the grassroots multilingual needs of the local community in times of crisis. The paper ends with implications for measures and strategies to enhance effective emergency language service and crisis communication for global multilingual cities.
