Characterization of inkjet printed silver-graphene films for health monitoring applications
No full textDigital manufacturing-based flexible and wearable strain sensors have gained much interest. Herein, inkjet-printed graphene/Ag nanoparticle piezoresistive strain sensors were experimentally investigated for human health monitoring applications. Initially, rectangular patterns were printed on polyethylene terephthalate (PET) substrate, and based on rectangular patterns dimensions, meander patterns design was implemented for sensing applications. Further, characterization and testing of samples were performed. The current-voltage characterization shows the ohmic behavior of hybrid ink-printed samples. The tensile test revealed sensitivity of printed samples fluctuates for applied strain range from 0.01-0.1 percent. However, the change in resistance measured during applied strain is diminutive. Meander pattern sensors demonstrated the ability to detect elbow joint movement and respiratory rate. This inkjet-printed, low-cost, flexible, and wearable sensor has the potential to monitor respiratory rate and bone joint movements continuously and can be explored for biocompatible health applications
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
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
Psychosocial risks experienced by international students in the security industry of New Zealand : a thesis presented in partial fulfilment of the requirements of the Master of Business Studies (specialisation in HRM), Massey University, Auckland, New Zealand
Full text linkMany international students in New Zealand are employed under non-standard work arrangements as part-time/casual security guards in the security industry. The literature on the experiences of international students indicates that they often work irregular schedules, are paid minimum wages and benefits, and tend to be exploited by employers due to their limited knowledge about employment rights. Similarly, the literature concerning work in the security industry worldwide suggests that security guards generally work under unsafe and hazardous working conditions and are provided with limited equipment and training, which tends to have negative repercussions for their psychosocial wellbeing. However, there is sparse literature at both the national and global level discussing the experiences of international students working as security guards in the security industry. Thus, the present research was designed to qualitatively explore the experiences of international students engaged in non-standard work arrangements in the security industry of New Zealand and investigate their psychosocial wellbeing. Seven international students working as casual security guards within the broader Auckland region were interviewed. Three main overarching themes were identified in the analysis. Theme 1 highlighted ‘accessibility issues’ identified as workers’ inaccessibility to adequate provisions such as Personal Protective Equipment (PPE), kitchen and toilet facilities, sufficient training, adequate income and benefits, regular working hours, and knowledge about employment rights; all of which had negative consequences for their wellbeing. Relatedly, theme 2 ‘threats to psychosocial wellbeing’ presented a picture of the vulnerability of international student security guards in the industry by illuminating their exposure to physical and psychosocial harm, such as physical abuse and racial harassment, during their work. Additional stressors due to this group’s extended engagement with both studies and part-time work were also explored. In theme 3, the ‘unprofessional practices’ of both international students and employers (subcontractors) in relation to New Zealand employment law were outlined. Here, sub-themes of exploitation and self-exploitation were further investigated. Overall these findings emphasised the need for vigorous policy initiatives focussed on improving the working standards of the security industry and wellbeing of international students working as security guards, through collaborative efforts on the part of the regulatory agencies, main- contractors and subcontractors
