Positioning, temporality, and emancipation in social research in projects for (or with?) forced migrants : some ethical implications.
Full text linkIn this proposal, we will reflect on some ethical implication of research involved in the co-construction of pilot experiences to support vulnerable persons – in particular asylum seekers and refugees – in their emancipating inclusion in the new countries of arrival. As researchers we have been members of research teams and partners in different EU projects; here we propose to draw on the experience of two European projects, which invested in building pilot experiences to support the inclusion of asylum seekers and refugees at several levels. Both the two projects are still ongoing, and in their final temporal phase.
When being part of a projecting process as researchers we deal with our ethical positioning: when constructing the proposal, when interacting with the different target groups, when giving back what has been experienced and analysed, when facing limits and constrains of potential successful pilots’ experiences. For this reason, in the design of multidisciplinary European research, a need to reflect upon and problematize several significant variables arises, and it involves both the resources, times, and vulnerabilities/criticalities of research, as well as the resources, times, and vulnerabilities/criticalities of the target subjects involved. Indeed, although these two planes should ideally align in terms of intentions and ethical considerations, sometimes they conflict. For instance, concerning the aspect of temporality, it is recognized that time represents a key issue in the experience of refugees. Simultaneously, it is acknowledged that time is a crucial factor for the success of the objectives that constitute the research project’s framework. Despite this, the timing of research projects is not always a guarantee for the formation of a new – and better – conception of the temporality of projects aimed at this target group. That being stated, we question how the research timeline is integrated with the migrants’ projects’ temporality and what ethical implications and questions arise from the convergence of these dimensions. Alongside the temporality notion, we also aim to reflect on how to foster the effective promotion of emancipatory change of migrants when research deals with the capitalization of project results. Overall, this contribution aims at investigating the deep interplay between the ethical principles of transformation, the social realities of refugees and migrants, and the actively involved subjectivities within the projects

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
CO2 sorption and diffusion in fluorinated polymers for carbon capture and transport application
No full textStudy on ammonia transport and separation in Aquivion® perfluoro sulfonated acid membranes
Full text linkThe present study reports the results of a series of sorption and permeation tests of pure ammonia as well as
nitrogen and hydrogen carried out on Aquivion C87-05 (short-side chain perfluoro sulfonic acid ionomer). Such
material is indeed of interest for possible applications in sustainable processes for ammonia production, either as
base material for polymer electrolyte membranes in low-temperature electrochemical ammonia synthesis or as a
membrane for effective product separation.
NH3, N2, and H2 permeation tests are performed at different temperatures (20, 35, and 50 ◦C) and both in dry
and humid conditions (R.H. up to 80%), aiming to assess the influence of these parameters on the resulting
permeabilities, while ammonia sorption is inspected at the same temperatures, and pressures up to near saturation conditions.
Pure ammonia permeability reached outstanding values around 7000 Barrer in dry Aquivion membranes,
revealing an increasing trend with upstream pressure, while it decreased with temperature. The same behavior is
recorded for NH3 solubility, indicating that sorption drives the ammonia transport through the membrane.
The obtained separation performances are found to be significantly better than those of other polymeric
membranes proposed for the same separations, as compared to a permeability-selectivity plot.The present study reports the results of a series of sorption and permeation tests of pure ammonia as well as nitrogen and hydrogen carried out on Aquivion C87-05 (short-side chain perfluoro sulfonic acid ionomer).

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
