Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
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

Studying high-z galaxies with [C II] intensity mapping
No full textWe investigate the [C II] line intensity mapping (IM) signal from galaxies in the Epoch of Reionization (EoR) to assess its detectability, the possibility to constrain the LC II-SFR relation, and to recover the [C II] luminosity function (LF) from future experiments. By empirically assuming that log LC II = log A + γ SFR ± σL, we derive the [C II] LF from the observed UV LF, and the [C II] IM power spectrum. We study the shot noise and the full power spectrum separately. Although, in general, the shot-noise component has a much higher signal-to-noise ratio than the clustering one, it cannot be used to put independent constraints on log A and γ . Full power spectrum measurements are crucial to break such degeneracy and reconstruct the [C II] LF. In our fiducial survey S1 (inspired by CCAT-p/1000 h) at z ∼ 6, the shot-noise (clustering) signal is detectable for two (one) of the five considered LC II-SFR relations. The shot noise is generally dominated by galaxies with LC II > 108-109 L☉ (MUV ∼ −20 to −22), already at reach of ALMA pointed observations. However, given the small field of view of such telescope, an IM experiment would provide unique information on the bright end of the LF. The detection depth of an IM experiment crucially depends on the (poorly constrained) LC II-SFR relation in the EoR. If the LC II-SFR relation varies in a wide log A-γ range, but still consistent with ALMA [C II] LF upper limits, even the signal from galaxies with LC II as faint as ∼107 L☉ could be detectable. Finally, we consider the contamination by continuum foregrounds (cosmic infrared background, dust, cosmic microwave background) and CO interloping lines, and derive the requirements on the residual contamination level to reliably extract the [C II] signal
Radio signals from early direct collapse black holes
No full textWe explore the possibility to detect the continuum radio signal from direct collapse black holes (DCBHs) by upcoming radio telescopes such as the SKA and ngVLA, assuming that after formation they can launch and sustain powerful jets at the accretion stage. We assume that the high-z DCBHs have similar jet properties as the observed radio-loud AGNs, then use a jet model to predict their radio flux detectability. If the jet power Pjet Z 1042-1043 erg s-1, it can be detectable by SKA/ngVLA, depending on the jet inclination angle. Considering the relation between jet power and black hole mass and spin, generally, jetted DCBHs with mass ≥ 105M⊙ can be detected. For a total jetted DCBH number density of ∼2.5 × 10-3 Mpc-3 at z = 10, about 100 deg-2z-1 DCBHs are expected to be above the detection threshold of SKA1-mid (100-h integration). If the jet 'blob' emitting most of the radio signal is dense and highly relativistic, then the DCBH would only feebly emit in the SKA-low band, because of self-synchrotron absorption (SSA) and blueshift. Moreover, the free-free absorption in the DCBH envelope may further reduce the signal in the SKA-low band. Thus, combining SKA-low and SKA-mid observations might provide a potential tool to distinguish a DCBH from a normal star-forming galaxy
Grammatical diversity across the yue dialects
No full textThere is a general belief that Yue constitutes a highly uniform dialect group, with its members sharing a good number of structures and lexica with the regional prestige dialect, Cantonese. Based on our first hand data collected from the field, this paper∗ describes the lesser known grammatical diversity across the Yue dialects, which can be illustrated by the different uses of the following features: (a) ideophonic suffixes; (b) diminutive suffixes and tone sandhi; (c) perfective aspect markers and their position in the VP, and (d) neutral question forms. The survey includes nine dialects from different subgroups, most of which are spoken far away from the Pearl River Delta where Cantonese dominates. Our study reveals that while Cantonese has obvious influence over other members of Yue, the grammatical diversity neutral question forms. The survey includes nine dialects from different subgroups, most of which are spoken far away from the Pearl River Delta where Cantonese dominates. Our study reveals that while Cantonese has obvious influence over other members of Yue, the grammatical diversity across Yue cannot simply be overlooked.</p
Pragmatic Case Studies as a Source of Unity in Applied Psychology
No full textTo unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe
How can one be perfected by music?—contemporary educational significance of Chinese pre-Qin Confucian thought on Yue Jiao (music education)
No full textMy dissertation project is an examination of aesthetic thought of Chinese pre-Qin Confucians with a focus on the idea of Yue Jiao (Music Education). Confucius, the founder of the Confucian School is regarded as the first educational philosopher in Chinese history both chronologically and in importance. A central theme in his aesthetics is that the final perfection of one’s personhood as an integrated whole is accomplished by the study of music. In this project, I will analyze key aspects in Confucian notion of music and education, and the links between those two and harmonized social relations. In my project, I propose to argue that education of a personhood as a whole is central to be a human being in today’s world. I suggest that aesthetic education, music education in particular, has an indispensible role in developing a harmonious balance between our rational intelligence and emotional sensibilities. Music education provides an ideal for living in the world today when unity is achieved without eliminating diversities.
My discussion of the contemporary educational significance of Yue Jiao contains two dimensions: (a) cultural, educational communications and mutual learning between the East and West; and (b) a reflective dialogue on education between history and the present. In the first dimension, I find considerable resonance and significant differences between Confucian aesthetics and key issues in ancient Greek aesthetics. Both traditions have a long history of the important role of music in human development and education. But they differ in their understanding of the foundation of musical value: for the ancient Chinese, it is emotive and social; for the ancient Greece, it is mostly rational.
With the second dimension, I argue that a close examination of Confucian thought on Yue Jiao will contribute to the reflection on the nature and role of education in today’s world. For how we educate a student to develop her personhood as a whole in a modern world of fragmentation and over specialization is the most critical question that educational philosophers must address. For this purpose, this project will discuss how ancient Chinese aesthetic traditions may bring new ways for us to understand contemporary educational problems and work on solutions, in ways that bear some relation to Western aesthetic traditions but also diverge in significant ways.Item withdrawn by Mark Zulauf ([email protected]) on 2012-06-26T14:12:08Z

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
