Asynchronous event-driven encoder with simultaneous temporal envelope and phase extraction for cochlear implants
No full textConventional cochlear implants using periodic sampling are power consuming and incapable of capturing the amplitude and phase of the input acoustic signal simultaneously. This paper presents an asynchronous event-driven encoder chip for cochlear implants capable of extracting the temporal fine structure. The chip architecture is based on asynchronous delta modulation (ADM) where the signal peak/trough crossing events are captured and digitized intrinsically, which has the advantages of significantly reduced power consumption, reduced circuit area, and the elimination of dedicated data compression circuitry. An 8-channel prototype chip was fabricated in 0.18 μm 1P6M CMOS process, occupying an area of 0.125 × 1.7 mm2 and has a power consumption of 36.2 μW from a 0.6V supply. A 16-channel stimulation encoding system was built by integrating two test chips, capable of processing the entire audible frequency range from 100 Hz to 10 kHz. Experimental characterization using the human voice is provided to corroborate functionality in the application environment
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

ABSTRACT
The primary purpose of this study was to investigate the factors on different parental background variables and related to circumstance in the parent-teacher cooperation, parent’s educational attitude and parent-teacher class cooperation participating satisfaction which happened when the parents engaged in the parent-teacher cooperation in junior high school classes in Taoyuan Country. The research subjects were participating in parent-teacher class cooperation in public junior high schools of Taoyuan country. The researcher designed the ‘Taoyan Parent-teacher Cooperation in class Questionnaire’ （TPCCQ） as the research tool. The questionnaire included personal information, scale of the parent’s educational attitude and parent-teacher class cooperation satisfaction. 520 participants were selected and asked to complete questionnaires and 501 of them were returned. The returning rate is 96.3%. Among them, 484 were valid. The valid rate reached 93%. The returning questionnaires were analyzed through descriptive statistics, factor analysis, chi-square, independent sample t-test, one-way ANOVA and product-moment correlation. The results were as follows:
1.Almost ninety percent of parents of junior high school students casually or rarely participate in the parent-teacher class activities.
2. parent-teacher contact approaches are mainly based on parent-teacher meeting, class meetings for parents, sports meet, parent-child activities, and celebration meetings of special festivals, together with other approaches.
3.When the parents contact the teachers, they often concern about bothering the teachers.
4.On parenting interaction attitude, frequent and casual participants are higher than rare participants in the class activities.
5.On the whole parent’s educational attitude, highly educated parents are higher than lower educated ones. Casual participants are higher than rare participants in the class activities.
6.On self-development satisfaction, frequent and casual participants are higher than rare ones in the class activities.
7.On the whole participating satisfaction of parent-teacher cooperation, casual participants are higher than rare ones in the class activities.
8.As for the correlation between parent’s educational attitude and parent-teacher class cooperation satisfaction, the result reveals that there are ‘positive’ correlations between the parents’ educational attitudes in junior high schools of Taoyuan and parent-teacher class cooperation participating satisfaction. The higher the parent’s educational attitude, the higher the parent-teacher class cooperation satisfaction.

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
