Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
Polyaniline/Cobalt Nanoparticle Composite Films
Get PDFPolymer nanocomposites have been gaining attention because of the enhanced properties of the element materials it can offer. These composites have been used in biological sector as well as quantum computing and memory devices. These are also used as different kind of sensors. Polymer composites incorporated with magnetic nanoparticles can modify the magnetic property of the nanoparticles and that has huge potential to be used in different sort of applications.
This work aims to develop a polymeric nanocomposite incorporating a conducting polymer and magnetic nanoparticles. The influence of the conducting polymer on the magnetic property of the nanoparticles was investigated. A composite film comprised of two different kinds of polymers was developed by using spin coating method. The nanoparticles were deposited on the film then. Different routes for deposition of the nanoparticles were investigated. Magnetic property of the film was investigated. Some changes in the composite should be made to make it suitable for many potential applications.

Education As Capital: Educated Bangladeshi Immigrant Women in 21st Century Britain
Get PDFThis thesis examines education within a transnational capital movement framework, investigating the experiences of first-generation educated Bangladeshi immigrant women arriving in Britain between 1999 and 2007. Pierre Bourdieu’s sociology of education (1973, 1990 [1977]), his notions of forms of capital (1986), and a feminist perspective on these theories are utilized to explain the interplay of class and gender in educating middle-class Bangladeshi women, the economic and social value of these academic qualifications in migration, and the gendered dimension of social reproduction in their diaspora. In the discussion of Bangladeshi women in Britain, this thesis for the first time deals with educated women from that background (as opposed to the majority Sylheti community that has been the subject of much research). Its primary data are in-depth interviews with twenty-eight highly-educated Bangladeshi women across England. In my methodology chapter I discuss, inter alia, the problematic of researching social equals, and the possibilities and limitations of ‘partial knowledge’ within that context. My in-depth analysis of the narratives around the participants’ family, upbringing, education and gender structure establishes the theoretical relevance of Bourdieu’s concept of education as cultural capital in post-colonial, resource-poor Bangladeshi society. In discussing gender and the internationalization of higher education in this context, I revise Bourdieu’s definition of ‘academic capital’, proposing three main categories that operate in my participants’ lives: namely ‘elite’, ‘standard’ and ‘general’ academic capital. This thesis challenges the argument that human movement and capital movement are similar and equal by analysing the differentiated values of academic qualifications and academic capital in the advanced, neoliberal labour market of Britain where the host country’s specific ‘cultural capital’ is at play. Finally, my thesis extends knowledge about immigrant women’s involvement in the developing diasporic ‘middle class’ with an investigation of these educated Bangladeshi women’s social lives and ‘mother work’ in the framework of social reproduction. This thesis develops an original and new dialogue between skilled migration, the Bangladeshi community in Britain, and the dynamic of gender and social class across borders, inviting further debates within and beyond feminist thoughts around educated middle-class women’s migration and its far-reaching consequences in the contemporary transnational world.

Electrical and Morphological Investigation of a Fe(II) Based Spin Crossover Complex and Its Composite
Get PDFSpin crossover (SCO) complexes have unique properties of switching their spin state upon perturbations like temperature, pressure, light, etc. Along with the spin state, different properties vary like structural, electrical, magnetic, optical properties. This enables these materials to be potentially used in various applications like molecular electronics, memory devices, switching devices, sensors and many more. To incorporate spin crossover materials into devices with efficient performance, the electrical behavior needs to be understood. This dissertation aims to investigate the effect of crystal structure on the electrical properties of iron(II) triazole spin crossover complex and how it can be modified for better performance.
In chapter two, materials for the experiments and various experimental methods are discussed. The third chapter of this dissertation reports two polymorphs of iron(II) triazole- nanoparticles and nanorods, and their crystallographic investigation. It also contains electrical conductivity studies on polymorphs. It was observed that conductivity changes with morphology and crystal properties.
The fourth chapter emphasizes how the conductivity changes with localized strain application on one of the polymorphs and it establishes a relationship between applied strain and conductivity. It was found that conductivity increases up to a certain strain and then it decreases with increasing strain. To manipulate this strain-dependent conductivity, the polymorph was incorporated with piezoelectric PVDF film to make a layer-by-layer composite film, which is reported in chapter five. It was found that the spin crossover couples with the piezoelectricity of the PVDF film, and the conductivity of the system increases. This will make the layer-by-layer film potential for future applications in different sensors and switches.

Poverty, Migration and Literature from below: Bangladeshi Labour Migrants’ Literary Expressions in Singapore
Get PDFIn neoliberal global economy, poverty is often theorised as an eradicable economic issue, partly depending on a poor country’s domestic and bilateral policies and partly on poor people’s initiatives (Kiely 2005). An individual’s migration to sell labour in a relatively rich country is considered a powerful personal strategy to make a leap from ‘poverty to prosperity’, affecting the migrant’s both local and national economy (The World Bank Report 2018). Labour migration is intricately linked with a person’s wider context of collective histories of aspirations, struggles and resistance. Using literary materials published in English (translated from Bangla) by Bangladeshi labour migrant poets and writers in Singapore, this paper analyses the centrality of these written texts to recreate migrants’ personal histories within their individual journey of poverty eradication. In such narratives, amigrant often appears as a precarious self being caught in a myriad of uncertainties in a foreign land. Thus, their narratives become a tool to destabilise the binary categories of a migrant’s home country as poor and the host country as rich. Instead, a labour migrant’s perception of poverty and material inequalities is expressed through what I call ‘literature from below’ where creative words become a political tool to resist any a-historical categorisation of labour migrant, poverty and its eradication. The words emerging from labour migrants’ lived experiences represent them both as agencies of eradicating poverty and workers living in an uncertain condition of economic and social precarity
