Introduction
No full textWe are proud to present this volume on Femininity and Psychoanalysis. It is an unruly collection, covering a vast area of thought. It is controversial no doubt because of the contributors’ choice of topics and the inevitably difficult decisions we had to make as editors in terms of whose voices we include in this volume, what is going to be discussed and put forward and what to leave for another occasion – simply at times for reasons of space. The book continues from the volume that Agnieszka edited in 2015 (Embodied Encounters) and Psychoanalysis and the Unrepresentable (2017), which we both edited, as we have done with this volume. It is interesting to observe how some debates continue and develop: one of them is the discussion about the importance of (or not) of sexual difference and its representations in culture and the clinic
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

No full textShort-term effects of olive mill waste water (OMW) on chemical and biochemical properties of a semiarid Mediterranean soil
No full textOlive mill waste water (OMW), a by-product of the olive mill industry, is produced in large amounts in Mediterranean countries. Olive mill waste water contains a high organic load, substantial amounts of plant nutrients but also several compounds with recognized toxicity towards living organisms. Moreover, OMW may represent a low cost source of water. Thus, the use of OMW for soil fertigation is a valuable option for its disposal, provided that its impact on soil chemical and biochemical properties is established. Investigations were performed on the short-term influence of OMW on several chemical and biochemical properties of a soil from a continental semi-arid Mediterranean region (Morocco). The soil was amended with 0, 18 and 36 ml 100 g-1 soil of OMW (corresponding to a field rate of 0, 40 and 80 m3 ha-1, respectively) and changes in various functionally related properties such as microbial biomass, basal respiration, extractable C and N, and soil hydrolases and oxido-reductases activities were measured over time. The variations of the main physical and chemical properties as well as the residual phytotoxicity of OMW amended and non-amended soils as assessed by tomato seed germination tests were also monitored. Temporary and permanent changes in several chemical and biochemical soil properties occurred following OMW application, thus being these properties varied in sensitivity to the applied disturbance. A sudden increase of total organic C, extractable N and C, available P and extractable Mn and Fe contents were measured. Simultaneously, a rapid increase of soil respiration, dehydrogenase and urease activities and microbial biomass (at 14 day incubation) of OMW amended soils occurred. In contrast, the activities of phosphatase, b-glucosidase, nitrate reductase and diphenol oxidase decreased markedly. The soil became highly phytotoxic after OMW addition (large decline of soil germination capability), mainly at 80 m3 ha-1 OMW. After 42 days’ incubation, however, a complete recovery of the soil germination capability and a residual phytotoxicity of about 30% were observed with 40 and 80 m3 ha-1 OMW, respectively. These findings indicate that the impact of OMW on soil properties was the result of opposite effects, depending on the relative amounts of beneficial and toxic organic and inorganic compounds present. The toxic compounds contained in OMW most likely counteracted the beneficial effect of organic substrates provided, which promoted the growth and activity of indigenous microorganisms
Changes in soil chemical and biochemical properties following amendment with crude and dephenolized olive mill waste water (OMW)
No full textOlive Mill Wastewater (OMW), a C-rich organic waste with high contents of both toxic phenols and valuable
nutrients, is yearly produced in large amounts in the Mediterranean area. A possible recycling option is to
spread it on agricultural land, provided that phytotoxic effects are neutralized. Research studies were
performed on the use of OMW for soil fertigation in a laboratory model system. It consisted of a soil,
representative of lands with dramatic water deficiency and very poor in organic matter content, supplied with
a given amount (80 m3 ha−1) of OMW as such (crude OMW, c-OMW) and after the removal of its toxic
phenolic compounds (dephenolized OMW, d-OMW). Dephenolized OMW was produced in a soil-slurry
stirred reactor containing an agricultural soil as catalyst. Several biochemical properties as well as the residual
phytotoxicity of the soil with and without the two OMW amendments were monitored over time (0–
42 days).
The tested enzymes, as well as the microbial and chemical soil properties, showed different patterns in
response to both crude and dephenolizedOMWaddition and time of incubation. As a general response several
properties of the soil, mainly biological, changed suddenly or at the most within 0–14 days after the addition
of the both kinds of OMW. Thereafter, most of them returned to their original values, showing the soil's
resilience capability. As compared to c-OMW amendment, the addition of d-OMW to the soil resulted in a
smaller impact onto soil performance as attested by the complete recovery of the soil germination capability, a
less inhibitory effect of some enzymatic activity (urease) and higher values of the respiratory quotient qCO2.
The application of OMW, mainly after removal of its phenolic components, may be suggested as a good
strategy for restoring soils in semiarid area and poor in organic matter
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
