Penelitian ini bertujuan untuk: (1) mengetahui gambaran pelaksanaan
pembelajaran Teaching Factory, (2) mengetahui gambaran kemampuan
beradaptasi siswa, (3) mengetahui gambaran prestasi siswa, (4) mengetahui
pengaruh pembelajaran Teaching Factory terhadap kemampuan adaptasi siswa,
(5) mengetahui pengaruh pembelajaran Teaching Factory terhadap prestasi belajar
siswa.
Penelitian ini menggunakan pendekatan Expost Facto karena variabel bebas
tidak diperlakukan khusus melainkan hanya mengungkap fakta berdasarkan
pengukuran gejala yang telah ada pada diri responden. Penelitian dilakukan di SMK
Kristen 2 Surakarta pada kelas XII program studi Teknik Mesin dengan responden
sebanyak 86 siswa. Pengambilan data penelitian menggunakan instrumen angket, dan
dokumentasi nilai praktikum. Instrumen angket terdiri dari 2 kategori, yaitu untuk
mengungkap data penerapan pembelajaran Teaching Factory dan kemampuan
beradaptasi. Dokumentasi nilai praktikum digunakan untuk mengungkap prestasi
belajar siswa. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif.
Uji validitas instrumen dilakukan dengan analisis korelasi Product Moment. Uji
reliabilitas instrumen dianalisis dengan teknik belah dua, Split Half Spearman Brown.
Uji persyaratan analisis menggunakan uji normalitas data dengan Chi Kuadrat.
Teknik analisis yang digunakan dalam menguji hipotesis adalah teknik uji regresi
linier sederhana.
Hasil penelitian menunjukkan bahwa: (1) pelaksanaan pembelajaran Teaching
Factory sebesar 48,84%, termasuk kategori cukup, (2) kemampuan adaptasi siswa
sebesar 38,37%, termasuk kategori cukup, (3) masing-masing harga mean untuk
nilai prestasi belajar siswa pra dan pasca pembelajaran Teaching Factory adalah
sebesar 7,35 dan 8,73, selisih kedua rataan sebesar 1,38 dengan peningkatan
persentase sebesar 8,61%, (4) tidak ada pengaruh pembelajaran Teaching Factory
terhadap kemampuan adaptasi siswa karena hasil uji regresi diperoleh nilai F uji
(1,878) < nilai F tabel (3,90), namun terdapat hubungan positif, sangat kuat serta
signifikan sebesar 0,99143 antara pembelajaran Teaching Factory dan
kemampuan adaptasi siswa (5) tidak ada pengaruh pembelajaran Teaching Factory
terhadap prestasi belajar siswa karena hasil uji regresi diperoleh nilai F uji (0,686)
< nilai F tabel (3,90). Walaupun demikian terdapat hubungan positif, sangat kuat
serta signifikan sebesar 0,992184 antara pembelajaran Teaching Factory dan
prestasi belajar sisw

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
Probabilistic ecotoxicological risk assessment of imidazolium ionic liquids with amino acid and halide anions
No full textIonic liquids (ILs) are chemical substances with good solubility and low vapor pressure because they are ionized and therefore charged. ILs may damage ecosystem due to their good water solubility. Toxicological studies for individual ILs. Major constraint in ILs ecotoxicology is that risk cannot be quantified by risk quotient methods because of unavailability of exposure assessment data. At present, only limited information is available about the impacts of ILs to aquatic ecosystems. The main objective of the current work is to use statistical methods to available literature on acute toxicity data of ILs to assess potential ecotoxicological risks when the ILs do come into industrial use. Probabilistic ecotoxicological risk assessment (PETRA) method was adopted by using Chemical Toxicity Distributions (CTDs) and Species Sensitivity Distributions (SSDs). SSDs has been used to derive threshold values below which the ecosystem and its biotic components could be protected from the adverse effect of ILs. CTDs has been used to estimate the probability of finding ILs with an effect below a calculated concentration which is considered to be safe environmental concentration. Acute toxicity data were collected from the literature on the acute toxicity of four bacterial pathogens Aeromonas hydrophila, Escherichia coli, Listeria monocytogenes and Staphylococcus aureus. CTD method was applied to assess the distribution of toxicities of group of IL to individual species. The SSD method was applied to estimate guideline values (GVs) to estimate different level of protection of bacterial species from ILs. Imidazolium chloride and bromide ILs were reported to pose more than 5 % risk towards bacteria. Out of the four bacterial strains, E coli was reported to be potentially at higher risk because of highest sensitivity when exposed towards ILs. The risk posed was five percent which is acceptable level of risk
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
