No full textABSTRACT: The development of inquiry learning has been performed on Chemistry Analytic II Practicum at Chemistry Analyst Department. This study is a classroom action research using 68 students of semester 2nd. Inquiry learning development that has been implemented in general has given the results of innovation learning in vocational education programs. Development of learning innovation is particularly relevant to the competency certification systems that have been developed in Professional Certification Agency (LSP UII). The lesson plan has been done contributed to improvements in the design of learning that refers to the Indonesian National Competency Standards in 2015.The development of inquiry learning can help the achievement of student competence. Achievement of competence from the knowledge aspect is done by using written test response test data, while from the attitude and skill aspect is measured from test practice test value. Mean of achievement of knowledge competence is 57.34 and mean of attainment of competency from attitude and skill aspect is 72.06. Competence is an assessment of knowledge, attitudes and skills that can be measured. Chemical Practicum Learning Analysis II is a process of inquiry learning conducted through a series of experiments so that the learning process should be supported by the understanding of the theory concepts that get in the classroom. Practicum learning is focused on achieving the competence of work attitude which gives birth to a standardized work culture and skills must be supported with sufficient knowledge.Data supporting the achievement of student competence can be measured through self assessment in three competency units, that is MSL973002A prepare work solution, MSL974001A prepare, standardize, and use solution and MSL974003A perform testing and chemical procedure that is in accordance with this course with SKKNI Field Laboratory Testing Services from Australian Laboratory Operations Training Package (MSL09). Assessment is done after the students follow the learning process inquiry with the development of learning video. Achievement of students' average student competency Semester 2nd of Chemical Analyst Department at three units of competence is 78.52%. During the learning process practicum, students are given learning tasks in preparing work solutions including preparing, standardizing and using the solution. Achievement rates on these units were 77.30% and 79.51%.The result of the learning development that has been done can give the improvement of the learning result according to the expected target. Learning outcomes can be obtained grades A was 70.74%. Assessment of students in learning practicum is an accumulation of the value of knowledge of pre-test and test responses of writing, the value of skills and attitudes of practicum activities, preparation of reports, seminars and practice test exams. Based on the results of the study showed that inquiry learning can help the achievement of learning outcomes.</jats:p

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
