Pengendalian Kerja Amali dan Cabaran Pembelajaran Abad Ke-21 dalam Mata Pelajaran Kimia
No full textKajian mengenai amalan pengajaran guru terhadap aplikasi Pembelajaran Abad Ke-21(PAK-21) telah dijalankan secara meluas. Namun, kajian yang sedemikian terhadap guru tingkatan enam masih terbatas. Malah kajian terhadap pelaksanaan kerja amali, khususnya mata pelajaran Kimia amat terhad. Oleh itu, kajian ini bertujuan meneliti cara guru Kimia tingkatan enam mengendalikan kerja amali terhadap pelajar dan memahami isu dan cabaran PAK-21 yang dihadapi oleh guru Kimia tingkatan enam dalam proses pelaksanaan kerja amali. Reka bentuk kajian melibatkan kaedah kualitatif ke atas guru mata pelajaran Kimia tingkatan enam di sekolah menengah kebangsaan dan kolej tingkatan enam di negeri Kedah yang dipilih secara persampelan bertujuan. Data kualitatif dikumpulkan dengan menggunakan protokol temu bual semi struktur ke atas enam guru. Seterusnya data kualitatif ini dianalisis secara analisis tematik dan menggunakan perisian Atlas.ti versi 9. Dapatan kajian ini memberi input tentang pengendalian kerja amali melalui tema perancangan dan pelaksanaan. Guru menghadapi cabaran dari segi infrastruktur, masa, kewangan dan kesediaan guru dalam menerapkan PAK-21 dalam kerja amali. Implikasi kajian ini akan menjadi rujukan dan panduan kepada guru dalam merancang PdPc yang berkesan
Hubungan minat dan penglibatan pelajar dalam kerja amali dengan pencapaian mata pelajaran pengeluaran tanaman
Get PDFMinat dan penglibatan pelajar dalam kerja amali pertanian memainkan peranan yang penting dalam Mata Pelajaran Aliran Vokasional Pengeluaran Tanaman di Sekolah Menengah Teknik Pertanian dalam menentukan pencapaian mereka kerana proses penilaian dalam peperiksaan Sijil Pelajaran Malaysia (SPM)
yang dilaksanakan berasaskan kerja amali pertanian, ini berbeza dengan proses penilaian pendidikan sewaktu mereka di sekolah akademik harian.
Data daripada kajian korelasi deskriptif ini dikumpul melalui soal selidik yang dibina berdasarkan literatur. Ujian pencapaian pula dibina sendiri oleh penyelidik. Dengan menggunakan formula pengiraan saiz sampel Crochran
pada paras keyakinan 95% (Crochran, 1977), bilangan sampel (n) yang digunakan adalah seramai 210 orang pelajar dengan menggunakan kaedah persampelan rawak berlapis. Stastistik deskriptif yang digunakan dalam menganalisa data dengan menggunakan frekuensi, min, sisihan piawai, ujian-t
dan ANOVA. Analisis stastistik inferens yang digunakan ialah Pekali Pearson,Ujian-t dan ANOVA. Dapatan kajian menunjukkan min bagi tahap minat pelajar dan tahap penglibatan pelajar yang diperolehi dalam kerja amali Pengeluaran Tanaman adalah sederhana tinggi. Dalam kajian ini didapati tidak terdapat hubungan yang signifikan antara minat dan pencapaian pelajar dalam mata pelajaran Pengeluaran Tanaman, juga tidak terdapat hubungan yang signifikan antara penglibatan pelajar dalam kerja amali dengan pencapaian dalam mata pelajaran Pengeluaran Tanaman. Bagaimanapun terdapat hubungan positif yang sederhana dan signifikan antara minat dan penglibatan pelajar dalam
kerja amali Pengeluaran Tanaman. Tahap pencapaian pelajar dalam ujian pencapaian adalah rendah dimana bilangan pelajar yang mendapat cemerlang adalah 0.5 % dari bilangan pelajar dan 60% pelajar cuma berada pada tahapyang lulus. Hasil kajian mendapati faktor Sekolah Menengah Pertanian adalah signifikan dan mempunyai hubungan sederhana dengan ujian pencapaian MPAV Pengeluaran Tanaman. Faktor demografi lain tidak signifikan dengan minat, penglibatan dan pencapaian
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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 vanishing author in computer-generated works: a critical analysis of recent Australian case law
Get PDFAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Poly(<scp>l</scp>-Lysine)–pyranine-3 coacervate mediated nanoparticle-assembly: fabrication of dynamic pH-responsive containers
No full textCounter-ion condensation of Poly(l-Lysine) in the presence of pyranine-3 generates spherical coacervates, which then template the assembly of silica nanoparticles to form microcapsule structures that dynamically control the optical ratiometric sensing of both the change in pH and release of the probe molecule.Amali AJ, 2008, CHEM COMMUN, P4165, DOI 10.1039-b807736c; Amali AJ, 2011, ANGEW CHEM INT EDIT, V50, P1318, DOI 10.1002-anie.201005619; Anker JN, 2008, NAT MATER, V7, P442, DOI 10.1038-nmat2162; Bagaria HG, 2011, J MATER CHEM, V21, P9454, DOI 10.1039-c1jm10712g; Bailey RC, 2003, J AM CHEM SOC, V125, P13541, DOI 10.1021-ja035479k; Barnadas-Rodriguez R, 2009, J PHYS CHEM B, V113, P1972, DOI 10.1021-jp806808u; Desmonts L.

Dissipative Range Scaling of Higher Order Structure Functions for Velocity and Passive Scalars
No full textDifferently to Kolmogorov's second similarity hypothesis, we find that the 2n-th order velocity and scalar structure functions scale with n-th order moment of the energy dissipation and the scalar dissipation, respectively. The origins of this scaling are analyzed by the transport equations of the fourth order velocity and scalar increment moments and by direct numerical simulations
