Autobiographism of Agnieszka Graff. Between essay, column and conversation
No full textAgnieszka Graff jest autorką tekstów akademickich i pozaakademickich. Podstawą artykułu jest analiza drugiej grupy tekstów, na którą składają się zbiory esejów, felietonów i rozmowy. Drugim czynnikiem wyznaczającym porządek artykułu jest chronologia. Kamieniami milowymi są tytuły książek Graff. Dzięki takiej konstrukcji zaobserwować można autokomentarze i nawiązania, motywy i wątki, do których wraca autorka. Tu najciekawsze są te, które traktować można jako znaki autobiograficznej postawy: autocytaty, pierwszoosobowa narracja, autotematyzm, czyli sygnały, które czytelniczka zdekoduje jako autobiograficzne oraz te, które składają się na autobiograficzną strategię (wstępy, posłowia, zawierające sugestie interpretacyjne). Celem artykułu jest próba odpowiedzi na pytanie o funkcje (auto)biografistyki u Agnieszki Graff. Analiza tekstów wynika z pytania o to, dlaczego Graff sięga po autobiograficzne narzędzia oraz jak i do czego je wykorzystuje.Agnieszka Graff is an author of academic and non-academic texts. An analysis of non-academic texts constitutes a basis for an article which includes sets of essays, columns and conversations. The second factor which determines the order in an article is chronology. The titles of her books are the mile stones. This structure allows to observe self-commentary, references and aspects, which she returns to. The most interesting are those which can be seen as the signs of autobiographism – self-citations, first-person narrative, mise en abyme. These are signs which the reader decodes as autobiographism and which constitute the autobiographic strategy (prefaces, afterwords which include interpretative hints). The aim of the article is an attempt to answer a question about the functions of (auto)biographism of Agnieszka Graff. Analysis of texts is a result of a question why Graff reaches for autobiographic instruments and in which way she uses these tools
Amphiscolops blumi Achatz, Hooge & Tyler, 2007, sp. nov.
No full textAmphiscolops blumi sp. nov. (Figs. 1–3) Amphiscolops sp.: Hooge & Tyler 2005 (p. 102). Diagnosis. Amphiscolops with seminal bursa filled with dense parenchymal tissue, 2–4 curved bursal nozzles, each measuring 80–120 µm in length. Male copulatory organ consists of a ciliated, glandular male antrum and a ciliated ejaculatory duct. A penis sac is absent, but numerous parenchymal muscles run through dense parenchymal tissue, which surrounds the antrum and the ejaculatory duct, and attach to the body wall. A caudal fold, or sperm guide (sensu Hyman 1937) covers the opening of the ejaculatory duct to the antrum. Setting the total body length to 100 units (100 U), the distance from the anterior tip of the body are as follows: st 11 U, m 48 U, fgp 73 U, mgp 77 U. Type Material. Holotype: USNM 1096735, one set of 1.5 -µm-thick serial sagittal sections of epoxyembedded specimen stained with toluidine blue. Paratype: USNM 1096736, one set of 1.5 -µm-thick serial sagittal sections of epoxy-embedded specimen stained with toluidine blue. Type Locality. In medium grained sand at the waterline on the northeast side of Carrie Bow Cay, Belize (16 ° 48 ’ 9.4 ” N, 88 °04’ 54.1 ” W). Other Material Examined. Living specimens in squeeze preparations, two complete sets of serial sections of epoxy-embedded specimens stained with toluidine blue, one partial set of epoxy-embedded specimen stained with Heidenhain’s hematoxylin, one whole-mount for fluorescence microscopy. Etymology. The species is named in honor and memory of Adolf Blum, Austria. Description. Mature animals are ~ 2 mm long and ~ 0.5 mm wide (Fig. 1 A). Cilia, ~ 7 µm long, occur on the entire body surface. The dorsal epidermis contains concrements that appear black in transmitted light, white in reflected light. The concrements are arranged in anastomosing starshaped patterns (Fig. 1 C) over the whole surface and form a spot in front the statocyst (Fig. 1 A). The epidermal nuclei are sunken beneath the body-wall musculature, which consists of outer circular muscles, crossover muscles, and longitudinal muscles. Body color is green-brown due to the presence of numerous, 20–24 µm wide zooxanthellae, which are scattered throughout the parenchyma (Fig. 1 B). Rhabdoid gland cells and mucous gland cells occur on the entire surface, rhabdoid gland cells most numerous dorsally and in the anterior part of the body, mucous gland cells most numerous ventrally. A frontal organ is absent. The nervous system consists of a brain positioned ventral to the statocyst, one ventro-lateral pair and two dorsal pairs of prominent longitudinal nerve cords. The statocyst lies ~ 200 µm behind the anterior tip. Two red ocelli lie lateral to it. The mouth lies slightly behind the middle of the body. The digestive syncytium is often filled with crustaceans (Fig. 2 A). The paired testes lie lateral and dorsal to the paired ovaries. Testes and ovaries originate behind the statocyst. The germative zone of the testes reaches back to the edge of the mouth. Sperm migrate to the copulatory organ and accumulate lateral and posterior to it (Fig. 1 B). Female follicles develop into oocytes or abortive eggs. Oocytes are flat, lobulated, and incorporate abortive eggs and algae. The female gonopore lies ~ 500 µm behind the mouth and ~ 100 µm in front of the male gonopore (Fig. 2 A). The short vagina opens into the seminal bursa caudally. Both are lined with parenchymal tissue. The seminal bursa is filled with dense parenchymal tissue and clusters of sperm (Fig. 2 B), which accumulate at the proximal end of the bursal nozzles. In mature animals, 2–4 curved bursal nozzles are present, each measuring 80–120 µm in length (Fig. 3 A). The male gonopore is positioned 250–300 µm in front of the posterior end (Fig. 2 A). It opens into a glandular male antrum dorsally and an ejaculatory duct caudally (Fig. 2 B). The antrum is a ~ 220 µm-wide, transverse slit, lined with the distal necks of gland cells, which contain granular cyanophilic secretions (Figs. 1 B, 2 B, C, 3 A). The antrum and the ejaculatory duct are both ciliated (Figs. 2 C, D). A caudal fold, or sperm guide (sensu Hyman 1937) covers the opening of the ejaculatory duct to the antrum (Figs. 2 B, 3 A). In some specimens sperm could be seen protruding into the proximal part of the ejaculatory duct. Beneath the ciliated epithelium of the ejaculatory duct lies a layer of circular muscles, which is constituted by parenchymal muscles and beneath this a layer of longitudinal muscles (Fig. 3 B). Numerous parenchymal muscles run through the dense parenchymal tissue, which surrounds the antrum and the ejaculatory duct, and attach to the body wall (Fig. 3 A). Remarks. Of the 12 known species of Amphiscolops (see Tyler et al. 2006), Amphiscolops blumi is most similar to Amphiscolops langerhansi (Graff, 1882) and Amphiscolops carvalhoi Marcus, 1952. All three species have a spherical seminal bursa filled with parenchymal cells, multiple bursal nozzles, which are long and curved, and a male copulatory organ with a large glandular antrum and an ejaculatory duct. We found tissue identical with the frontal gland cells (Stirndrüsen) shown by Graff (1904) in figures 1, 2 and 3 of plate 12. Contrary to his interpretation we found this tissue to be nervous tissue. Consequently the three species are additionally united by the absence of a frontal organ. Like A. carvalhoi, A. blumi is about half the size of A. langerhansi (2 mm in length vs. 4–5 mm in length of A. langerhansi) and has similar number of bursal nozzles (2–4 compared to 2–6 in A. carvalhoi), fewer than in A. langerhansi (which has 6–11). Patterns of coloration are somewhat different in these three species as well. The epidermal concrements are white in both, A. blumi and A. langerhansi, golden in A. carvalhoi. The pattern of their distribution in A. blumi is similar to that of A. langerhansi (compare figure 1 A with Graff’s (1904) figure 6, plate 11 of A. langerhansi), including a dense aggregation of concrements in front of the statocyst and, in some specimens, aggregations into longitudinal stripes as has been described also for some specimens of A. langerhansi (Graff 1904). A. carvalhoi lacks these aggregations, and it also has two post-cerebral spots bare of concrements. Graff (1904) did not discern in A. langerhansi the star-like shape of concrements Marcus (1952) and we noted in A. blumi and A. carvalhoi, respectively, perhaps because he used lower magnifications in his investigation. A. blumi and A. langerhansi are oviparous, A. carvalhoi is viviparous. In having a ciliated epithelium lining both the male antrum and the ejaculatory duct, A. blumi is similar to A. langerhansi as Graff (1904) described it. Hyman’s (1937) account of copulation in specimens of A. langerhansi from Bermuda, however, describes her specimens as lacking ciliation in both the antrum and the duct; confounding identification of these specimens, however, is that they had fewer bursal nozzles (2–8) than originally described for A. langerhansi. Marcus (1952) reported cilia in only the male antrum of A. carvalhoi. Conceivably, however, the numerous gland cells of the male antrum in A. carvalhoi could have obscured ciliation here. From several masses of floating Sargassum sp. gathered near Carrie Bow Cay, we collected acoels similar in appearance to A. blumi. Although some of these specimens had eggs, none had male copulatory organs, and as such, we were unable to determine if they were conspecific to A. blumi.Published as part of Achatz, Johannes G., Hooge, Matthew D. & Tyler, Seth, 2007, Convolutidae (Acoela) from Belize, pp. 35-66 in Zootaxa 1479 on pages 37-41, DOI: 10.5281/zenodo.17682
Ramiellona lasiura Graff 1957
No full textRamiellona lasiura (Graff, 1957) Howascolex (Graceevelynia) lasiurus Graff, 1957: 129. Figs. 16-19 Ramiellona lasiura: Gates 1962: 215. Gates (1962) transferred this species to Ramiellona, considering that it has only meronephridia and lacks holonephridia. This author pointed out that in the original description several characters were not indicated or wrongly placed. Thanks to the kindness of Dr. J. Römbke, in 1987 the first author of this paper had the opportunity to briefly see the holotype of this species (Naturmuseum Senckenberg, Frankfurt, Cat No. 2783). Accordingly, with respect to the original description the species diagnosis should be modified as follows: One gizzard in segment 5 (not in 6 as in the original description). Calciferous glands in segments 8–12 (9–13 in o.d.). Only one pair of seminal vesicles in segment 12 (doubtful in 11 in o.d.) and one pair of iridescent male funnels in 11 (not seen in o.d.). It was not possible to assert the position and number of hearts because they had been removed; however, since the position of the gizzard is in 5 and not in 6 as originally described, it is highly probable that also the hearts are located one segment more anteriorly, i.e. not in 9–13 but in 8–12. As Gates (1962) already suggested, we found that R. lasiura is a metandric species with its gizzard placed in the usual position for this genus and with last hearts probably in segment 12.Published as part of Fragoso, Carlos & Rojas, Patricia, 2014, New species and records of the earthworm genus Ramiellona (Annelida, Oligochaeta, Acanthodrilidae) from southern Mexico and Guatemala, pp. 549-572 in Zootaxa 3753 (6) on page 568, DOI: 10.11646/zootaxa.3753.6.3, http://zenodo.org/record/22429

Changes in coping strategies among women receiving treatment for alcohol use disorders (AUDs)
No full textThis study examined coping and change in coping among a sample of 158 women entering a randomized clinical trial of cognitive-behavioral therapy (CBT) for an alcohol use disorder (AUD). This is a secondary analysis of data collected as part of a larger two-armed trial of different models of individual and couples therapy for women with AUDs. Study aims were to describe the initial coping strategies -- including demographic, psychological, and substance use correlates -- of women entering treatment, examine change in coping during and following treatment, examine change in coping as a function of treatment attendance and engagement, and explore the relationship between coping and change in coping as predictive of longer-term drinking outcome. Participants were recruited from the community and were: at least 18 years old, in a stable relationship with a male partner, met DSM-IV AUD criteria, and had used alcohol in the 30 days prior to recruitment. Coping was assessed with the Coping Behaviours Inventory (CBI) (Litman et al., 1983) administered at four time points: at baseline, after 12 weeks of treatment, and at follow-up assessments six and twelve months after treatment. Women entered treatment with a comparatively high degree of cognitive versus behavioral coping strategies, and total coping followed a quadratic shape and increased during treatment. Attendance was positively associated with change in coping during treatment, while homework completion was not. Coping and change in coping was predictive of fewer drinking days at follow-up as well as greater likelihood of abstinence. However, for a portion of women still drinking, coping was also associated with greater drinks per drinking day. Implications and next steps are discussed.Psy.

Curini-Galletti leg. (Genbank accession MF185684 -96). Type locality ITALY: Gulf of Naples, Tyrrhenian Sea. Deposition not recorded. Habitat Marine, sublittoral phytal in algae (e.g., Sargassum sp.) or benthal on shells, fine sand and mud. Distribution Ireland: New Harbor, Galway, 1–2 m; Malahide Inlet, Dublin, 2 m (Southern 1936). England: Wembury (Meixner 1938). Faroe Islands: Vaagfjord, Suderø, 10 m (Steinböck 1931). France: Concarneau (von Graff 1913). Iceland: North of Ísafjörður, 1–2 m (Steinböck 1938). Sweden: Gullmar Fjord, Fiskebäckskil, 1–2 m (Westblad 1953; pers. obs. by author). Norway: Herdla (Westblad 1934; Karling 1953). Population description Microstomum with field of bright red pigmentation spots on each well-developed zooid; length of pigmentation stretches from just below the anterior tip to halfway to the brain, width of pigmentation somewhat variable: either predominately at the lateral margins and thinning toward the middle or, most frequently, a band that encircles the entire body (Fig. 4A). Other small orange-red droplets may be scattered within the parenchyma of some specimens, particularly around the anterior and pharynx (Fig. 4B–C). Body otherwise colorless, clear and reflective of intestine. Vegetative chains to four zooids long; maximum animal/zooid body length 2000/1400 µm. Body width generally consistent, accepting slight constrictions between zooids and at the level of the ciliary pits; slightly tapering toward the rounded anterior end. Posterior end bluntly rounded. Posterior rims of welldeveloped zooids with many 5–6-µm-long posterior adhesive papillae (Fig. 5). Epidermis uniformly covered with cilia. Bundles of 3–8 nematocysts present, scattered in the parenchyma (Karling 1966); each nematocyst 4–6 µm long (Fig. 4C). According to Westblad (1953), expelled nematocysts along the lateral body margins may resemble papillae. Mouth slit-like at rest, but able to distend to encompass very large food. Pharynx spherical to elliptical, encompassing up to the length of the second quarter of the zooid. Preoral gut extending to brain or slightly anterior. Intestine yellow-brown or tinged with red or pink; may contain ingested prey. Male reproductive system with paired testes located anterolaterally to male copulatory apparatus and gonopore (Figs 4D, 5). Testes round, average diameter 47 µm, containing little or no sperm. Vasa defferentia connect individually to circular vesicula seminalis. Numerous prostatic glands insert anteriorly in vesicula seminalis and extend ventrally around the center of stylet (Fig. 4D–E). Stylet a single, wide spiral bent around a 90° angle, terminating in a ~10-µm-long fingerlike hook (Figs 4E, 5C–D); average length 95 µm (range 75–112 µm); width largest at the base, ~12 µm, tapering only slightly towards the distal end, ~5 µm at the base of the hook; opening subterminal. Stylet projects into a ciliated antrum masculinum (Fig. 4A, D). Female reproductive system typical for the genus (Figs 4D, 5). Single ovary situated mid-body, ventral to intestine, leading to ciliated female antrum. Female gonopore separate. Eggs develop caudally. Remarks Collected specimens generally appeared morphologically similar to the type description (von Graff 1882) and to previous accounts of M. rubromaculatum from Fiskebäckskil. Westblad (1953) recorded M. rubromaculatum from Fiskebäckskil with vegetative chains up to four zooids long, yet all currently collected specimens except one were composed of either two weakly developed zooids separated by a faint fission plane or one or two well-developed zooids only. This follows other patterns found in species of Microstomum in which slender chains of multiple, short zooids dominate during the asexual reproductive phase of the lifecycle while larger single or double zooid animals dominate during periods of sexual reproduction (Bauchhenss 1971). The amount of eyespot pigmentation in M. rubromaculatum can greatly vary between individuals. Specimens from Fiskebäckskil generally agreed with the original description of Graff (1882): paired, lateral eyespots composed of an accumulation of red pigmentation that extends medially to form a ring around the anterior end. However, pigmentation spots in four of the observed specimens remained clearly distinct, a phenomenon that has been recorded in other populations of M. rubromaculatum (von Graff 1913; Steinböck 1931). COI sequences were identical between specimens with two distinct eyespots and those with a circular band, which indicates amount of pigmentation is not necessarily a systematically important character. Rather, accumulation of eyespot pigmentation may be more “correlated with light intensity”, as in, e.g., Microstomum lineare (Bauchhenss 1971). Steinböck (1938) reported a single specimen of M. rubromaculatum from Iceland with a large central pigment spot that thinned toward the body margins. However, such a pattern was not observed in any of our specimens, nor otherwise recorded in any other population. Red-orange droplets (Fig. 4B–C), that have not been previously documented in M. rubromaculatum, were observed in 18 of the 20 live specimens. The droplets ranged in size from a diameter of ~2–10 µm and were most often located anteriorly, especially around the pharynx. The droplets were most likely lipid deposits whose presence and coloration stems from ingested food. While such deposits have not been recorded before in Microstomum, colored lipid droplets are known to occur in other species of Macrostomorpha (Rieger et al. 1991). The distribution of Microstomum rubromaculatum is wide, with populations reported from the Mediterranean, the North Sea and the Baltic. Although such patterns do occur for other macrostomorphs (e.g., Macrostomum pusillum, M. rubrocinctum, Paramalostomum dubium – see Ax 1956; Karling 1974; Armonies 1988), including other species of Microstomum (e.g., M. lineare, M. papillosum – see Steinböck 1931; Karling 1974), the distribution may still be considered surprising giving the large geographic distances and differences in salinity and temperature (Boyer & Levitus 1994). Evidence has increasingly shown that widespread taxa previously thought to represent a single species are in fact morphologically indistinct complexes. However, all our specimens were collected from a single location in west Sweden, and thus different populations of M. rubromaculatum could not be compared at this time. Sexually mature specimens of M. rubromaculatum have not been recorded from any other populations, including those inhabiting the type locality, and therefore further research may be necessary to confirm the identity of M. rubromaculatum from Fiskebäckskil, Sweden before sexual anatomy can be included in the description of the species as a whole. Phylogeny The maximum likelihood analysis found four moderately or highly supported clades of Microstomum (Fig. 6). M. rubromaculatum was sister to M. edmondi sp. nov. with moderate support and further formed a clade with an unidentified species of Microstomum (species “D” in Janssen et al. 2015; see Table 1) and M. laurae sp. nov. The other three species of Microstomum represented in the analysis (species “B” in Janssen et al. 2015, M. lineare, M. papillosum) individually comprised the remaining three clades. Patristic distances are presented in Table 2. A true understanding of the evolutionary relationships within Microstomum would require multiple nuclear and mitochondrial gene sequences as well as a much greater species representation (Maddison 1997). However, the results of the ML analysis and patristic distances presented here clearly separate specimens of M. edmondi sp. nov., M. laurae sp. nov. and M. rubromaculatum into three distinct lineages representing the three species.Published as part of Atherton, Sarah & Jondelius, Ulf, 2018, Microstomum (Platyhelminthes, Macrostomorpha, Microstomidae) from the Swedish west coast: two new species and a population description, pp. 1-18 in European Journal of Taxonomy 398 on pages 10-15, DOI: 10.5852/ejt.2018.398, http://zenodo.org/record/116048
