Dispelling the Myths Behind First-author Citation Counts
No full textWe 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

Quantitative Interpretation of Gravity Anomaly Data in Geothermal Field Seulawah Agam, Aceh Besar
No full textSurvei metode Gravitasi telah dilakukan di lapangan panas bumi Seulawah Agam, Aceh Besar, Provinsi Aceh untuk menentukan struktur bawah permukaan daerah tersebut. Distribusi percepatan gravitasi telah diukur dengan menggunakan instrumen Gravitimeter Scintrex CG-5. Pengukuran dilakukan pada dua lintasan. Lintasan pertama sepanjang 10 km dan lintasan kedua sepanjang 5,5 km dengan total panjang lintasan 15,5 km. Data diukur secara berturut-turut pada 33 titik dan 21 titik untuk lintasan pertama dan kedua. Untuk mendapatkan nilai Anomali Bouguer Lengkap, beberapa standar koreksi data diterapkan termasuk koreksi drift, koreksi pasang surut, koreksi lintang, koreksi udara bebas, koreksi Bouguer, dan koreksi medan. Data nilai Anomali Bouguer Lengkap sepanjang profil digunakan untuk pemodelan maju (forward modeling) 2D menggunakan software Grav2DC. Model menunjukkan bahwa struktur bawah permukaan daerah penelitian terdiri dari tiga lapisan. Lapisan paling atas ditafsirkan sebagai lapisan tufa pasiran (ρ = 2,09 g/cm3), dan diikuti oleh lapisan lempung dibawahnya (ρ = 2,02 g/cm3). Lapisan terbawah diduga sebagai breksi vulkanik (ρ = 2,17 g/cm3). Breksi vulkanik dapat dianggap sebagai lapisan reservoir dan lapisan clay sebagai lapisan penutup (cap rock) pada sistem panas bumi di Gunung Api Seulawah Agam.Kata Kunci: Metode Gravitasi, Densitas, Grav2DC, Sistem Panas Bumi, Seulawah Agam
Survey on gravity method has been done in Seulawah Agam geothermal field, Aceh Besar, Aceh Province to determine the subsurface structure of the area. We have measured distribution of acceleration gravity using Gravitimeter Scintrex CG-5 instrument. The measurements were carried out along two profiles. Length of the first profile is 10 km and the second profil is 5,5 km with the total profile length is 15,5 km. The data were measured at 33 and 21 stations for the first and the second profile respectively. In order to obtain a Complete Bouguer Anomaly value, some standard data corrections were applied including drift correction, tidal correction, latitude correction, free air correction, Bouguer correction and terrain correction. Complete Bouguer Anomaly value data along the profile were use for 2D forward modeling using Grav2DC software. The models show that subsurface structure of the area consist of 3 layers. The upper most layer is interpreted as sandyceous tuffastones (ρ = 2,09 g/cm3), and followed by underlaying clay layer (ρ = 2,02 g/cm3). The lowest layer is expected as volcanic breccias (ρ = 2,17 g/cm3). The volcanic breccias can be considered as reservoir and the clay layer as a cap rock in geothermal system of Seulawah Agam vulcano.

Effect of prolonged phenytoin administration on rat brain gene expression assessed by DNA microarrays
No full textPreliminary clinical trials have recently shown that phenytoin, an antiepileptic drug, may also be beneficial for treatment of bipolar disorder. To examine molecular mechanisms of action of phenytoin as a potential mood stabilizer, DNA microarrays were used to study the effect of phenytoin on gene expression in the hippocampus and frontal cortex of Sprague-Dawley rats. While our particular interest is in bipolar disorder, this is the first DNA microarray study on the effect of phenytoin in brain tissue, in general. As compared with control rats, treated rats had 508 differentially expressed genes in the hippocampus and 62 in the frontal cortex. Phenytoin modulated the expression of genes which may affect neurotransmission, e.g. glutamate decarboxylase 1 (Gad1) and gamma-aminobutyric acid A receptor, alpha 5 (Gabra5). Phenytoin also exerted an effect on neuroprotection-related genes, namely the survival-promoting and antioxidant genes v-akt murine thymoma viral oncogene homolog 1 (Akt1), FK506 binding protein 12-rapamycin associated protein 1 (Frap1), glutathione reductase (Gsr) and glutamate cysteine ligase catalytic subunit (Gclc). The expression of genes potentially associated with mechanisms of mood regulation such as adenylate cyclase-associated protein 1 (Cap1), Glial Fibrillary Acidic Protein (Gfap) and prodynorphin (Pdyn) was also altered. Some of the above genes are regarded as targets of classical mood stabilizers and their modulation supports the clinical observation that phenytoin may have mood-stabilizing effects. The results may provide new insights regarding the mechanism of action of phenytoin and genes found differentially expressed following phenytoin administration may play a role in the pathophysiology of either bipolar disorder or epilepsy

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
No full textAnswering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
