Sopa, Sopa, SOPA! : En studie om curling på en kraftplatta
No full textSyfte Detta arbete skall illustrera vilka vertikala och horisontala krafter samt impulser som finns inom curling sopad med borste på en artificiell yta. Frågeställningen är följande: • Vilken kraft i Newton och Newtonsekund skapar en sopande curlingspelare? • Vilket förhållandet av samband mellan högt antal sopcykler och hög impuls vid sopning i curling råder? • Finns en signifikant skillnad mellan tre set av maximalsopning i form av sjunkande impuls? Metod Testgrupp bestod av nio curlingspelare, tre kvinnor och sex män deltog (m=30,7+5,7år, 76,667+8,43kg). En uppvärmning genomfördes med tio minuters cykling på en ergometercykel, Monark 318, och 15 armhävningar. Testet bestod av tre delar, del ett maximalt tryckförsök, del två sopning 10 sekunder, del tre sopning 25 sekunder i tre set. Avslutande test var tre upprepningar på 25 sekunder med maximal sopning. Vila på 60 sekunder mellan set. Sopningen utfördes på en polyetenplatta som var fastskruvad på en kraftplatta (Type 9281 BII, Kistler Instrumente AG, Winterthur, Schweiz). Polyeten har en friktionsegenskap för att kunna återskapa känslan av is. De impulser som skapades under försöket överfördes till en PC där data lagrades för analysering och beskådning i diagramform. Resultat prövades med Pearmans rangkorrelationkoefficient och Students t-test. Varje försöksgrupp gjorde ett besök när samtliga försök genomfördes. Sopcykler användes för beräkning av frekvenser från försöksunderlaget. Resultat Det maximala vertikalkraftens medelvärde för alla försökspersoner är på 682= +119N. Impulsvärdet låg på medelvärde 185+103Ns . Under tio sekunder kan en curlingspelare skapa en vertikal kraft 221=+52N, en horisontal kraft 54+16N samt en vertikal impuls 2 240+454Ns med ett antal sopcykler mellan 35 och 49 stycken (m= 39,444+4,61). Under 25sekunder sopning kan en curlingspelare skapa en vertikal kraft 195+39N, en horisontal kraft 46+15N samt en vertikal impuls 5 172+739Ns med sopcykler mellan 82 och 104 89,667+7,14Ns. Inget signifikant samband fanns mellan hög vertikal eller horisontal impuls och högt antal sopcykler. Uttröttning gav ingen signifikant skillnad i sjunkande impuls med ett parat t-test mellan de medelvärden som beräknats mellan de tre avslutande maximala sopningar under vardera 25sekunder med alfa-niva 0.05. Slutsats Studien har gett en referensram för framtida studier vad gäller kraft och impuls. Inget förhållandet kunde ges mellan högt antal sopcykler och hög impuls. Inga signifikanta skillnader mellan tre set av maximal sopning fanns.Specialidrottstränarprogrammet 2001-200
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
Variations on the Author
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
The Effect of Instructional Leadership School Principles, Teacher Innovation and Supervision in The Quality of Learning Management at Muhammadiyah Jakarta Senior High School
Full text linkThis study aims to determine the effect of instructional leadership, teacher innovation and supervision on the quality of learning management at SMA Muhammadiyah Jakarta. The location of the research was carried out at SMA Muhammadiyah South Jakarta. The research method used in this study was a survey method, with a population of 178 teachers with a sample of 123 teachers. The research instruments consist of learning management quality instruments, instructional leadership instruments, teacher innovation instruments and supervision instruments. The research results obtained (1) there is a positive direct effect of instructional leadership on the quality of learning management, (2) there is a positive direct effect of teacher innovation on the quality of learning management, (3) there is a positive direct effect of supervision on the quality of learning management, (4) there is a positive direct effect of instructional leadership on supervision, (5) there is a positive direct effect of teacher innovation on supervision, and (6) ) there is a positive direct effect of instructional leadership on teacher innovation. The implication of this research is that if you want to improve the quality of learning management, you must strengthen instructional leadership, teacher innovation and supervision. Suggestions that the quality of learning management is increased, all parties, namely the education office, school principals and the Muhammadiyah organization provide support for the research results that have been obtained
Implementation of the New MABIMS Crescent Visibility Criteria: Efforts to Unite the Hijriyah Calendar in the Southeast Asian Region
Full text linkThis paper discussed the implementation of the new MABIMS hilāl visibility criteria in the unification of the Hijriyah calendar in member countries (Malaysia, Brunei, Indonesia and Singapore). This research uses the approach of Astronomy and Grindle's theory of policy implementation. The data source comes from the MABIMS Muzakarah results document and related articles. The research results indicate that the new MABIMS moon crescent visibility criteria are part of a public policy that, in its implementation, requires two mutually supportive variables. First, the content of the policy in the form of the moon crescent visibility criteria (3⁰; 6.4⁰) was accepted by all member countries through the signing of an ad referendum on 8 December 2021. This acceptance will receive public support if it is beneficial to time management. Second, the context of implementation is carried out in stages by taking into the characteristics of the institutions involved in preparing the Hijriyah calendar. At the practical level, the policy can be well received by the public, except in Indonesia, which still faces obstacles. This is due to the policy in the three countries being carried out on a top-down basis, while in Indonesia, it is carried out on a bottom-up basis. Furthermore, determining of Ramadan, Shawwal, and Zulhijjah are still waiting for confirmation of the sighting of the moon (ru’yah). It related to the domination of ru’yah, and a strong distinction between the function of the calendar in civil administration and worship practice. Abstrak Makalah ini membahas penerapan kriteria baru visibilitas hilalMABIMS dalam penyatuan penanggalan Hijriyah di negara-negara anggota(Malaysia, Brunei, Indonesia dan Singapura). Penelitian ini menggunakanpendekatan penerapan kebijakan Astronomi dan teori Grindle. Sumber databerasal dari dokumen hasil Muzakarah MABIMS dan artikel terkait. Hasilpenelitian menunjukkan bahwa kriteria baru visibilitas hilal MABIMS merupakanbagian dari kebijakan publik yang dalam pelaksanaannya membutuhkandua variabel yang saling mendukung. Pertama, isi kebijakan berupa kriteriavisibilitas bulan sabit (3⁰; 6.4⁰) diterima oleh seluruh negara anggota melaluipenandatanganan referendum pada 8 Desember 2021. Penerimaan ini akanmendapat dukungan publik jika bermanfaat hingga manajemen waktu. Kedua,konteks pelaksanaannya dilakukan secara bertahap dengan memperhatikankarakteristik lembaga yang terlibat dalam penyusunan penanggalan Hijriyah.Pada tataran praktis, kebijakan tersebut dapat diterima dengan baik olehmasyarakat, kecuali di Indonesia yang masih menghadapi kendala. Hal inidisebabkan kebijakan di ketiga negara dilakukan secara top-down, sedangkan diIndonesia dilakukan secara bottom-up. Selanjutnya, penentuan awal Ramadan,Syawal dan Zulhijah masih menunggu konfirmasi penampakan hilal (rukyah).Ini terkait dengan dominasi ru’yah, dan perbedaan yang kuat antara fungsipenanggalan dalam administrasi sipil dan praktik ibadah.</jats:p
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
