Visual representation in the work of Joseph Roth, 1923-1932
No full textThrough an examination of Joseph Roth’s reportage and fiction published between 1923 and 1932, this thesis seeks to provide a systematic analysis of a particular aspect of the author’s literary style, namely his use of sharply focused visual representations, which are termed Heuristic Visuals. Close textual analysis, supplemented by insights from reader-response theory, psychology, psycholinguistics and sociology illuminate the function of these visual representations. The thesis also seeks to discover whether there are significant differences and correspondences in the use of visual representations between the reportage and fiction genres. Roth believed that writers should be engagiert, and that the truth could only be arrived at through close observation of reality, not subordinated to theory. The research analyses the techniques by which Roth challenges his readers and encourages them to discover the truth for themselves. Three basic variants of Heuristic Visuals are identified, and their use in different contexts, including that of dialectical presentations, is explored. There is evidence of the use of different variants of Heuristic Visuals according to the respective rhetorical demands of particular thematic issues. It has also been possible to establish synchronic correspondences between the different genres, and diachronic correspondences within genres. Although there are examples within the reportage where the entire article is based on an Heuristic Visual, the use of Heuristic Visuals cannot be seen as a key organizing principle in Roth’s work as a whole. As his mastery of the technique reaches its highest point in the early 1930s, Heuristic Visuals are often incorporated into the reconstruction of a complete sensory experience. Analysis of Roth’s heuristic use of visual representations has led to important insights, including a reinterpretation of the endings of Roth’s two most famous novels: Hiob and Radetzkymarsch
Methodologies for identification of drainage structures: space filling vs. hydrodynamics
No full textThe concept of slope scaling with contributing area proposed by LaA Barbera and Roth [this volume] is used as an indicator of channel initiation and for channel maintenance. This concept is shown to be a useful criterion for the identification of the effective drainage structure of the basin; existing Digital Terrain Models (DEMs) are used for the purpose. Integral properties of the single DEM pixel are introduced in order to reduce
the noise due to a possible DEM low accuracy, e.g. in the estimation of the local slope value from the elevation data set. The resulting network is characterized by a non unifonn drainage density

No full textIn the contemporary academic world, dominated by “ready-made receipts” for explaining psychological processes, Roth and Jornet took upon themeselves the hard task of revising Vygotsky legacy on the basis of Spinoza’s relevance in his thinking. The authors focused on the Russian scholar’s “later years”, almost still unknown worldwide to both the large audience and serious specialists in educational psychology and adjacent areas. The book greatly contributes to the consolidation of a cultural psychology’s perspective in education to restore the relevance of a general theoretical elaboration against the flattening of present-day educational psychology

The effect of sodium butyrate on growth and intestinal microflora of weanling pigs (Einfluss von Na-Butyrat auf Wachstum und intestinale Mikroflora von Absetzferkeln). G. Biagi*, E. Vezzali, A. Piva and F.X. Roth – Bologna/Freising-Weihenstephan
The period of five to eight weeks after weaning is a critical stage in most pork production systems. In the recent past, these problems were counteracted with widespread use of antibiotic substances and auxinic agents that may select antibiotic-resistant genes in intestinal pathogens with the possibility of a cross spread to human pathogens. Adding organic acids to piglet diets has been reported to be helpful in overcoming problems of the post-weaning period (1). Butyric acid is known to be the main energy source of the hindgut mucosa and has shown positive effects on growth when fed to weaned pigs (2). Aim of this study was the evaluation of the effect of feeding sodium butyrate (SB) on piglet growth and intestinal microflora.
Methods: Immediately after weaning, 48 piglets were divided into four groups (12 animals per group, housed in individual cages) for a six week trial. Treatments were a commercial diet with a) no addition (control diet) or with b) 0.1%, c) 0.2%, and d) 0.4% of SB. Feed and water were provided ad libitum. Animals were weighed every week and feed consumption was recorded. At the end of the trial, six animals per group were killed. Samples of jejunum and caecum content were cultured for viable bacteria and pH, ammonia and short-chain fatty acids (SCFA) were determined.
Results: Feeding SB at 0.4% improved piglet growth (P < 0.10). Intestinal bacterial counts and pH did not show any differences; lactobacilli in jejunum and lactobacilli, coliforms and clostridia in caecum averaged 6.1, 8.5, 6.6, and 6.2 log cfu/ml, respectively. Feeding 0.4% SB resulted in higher caecal ammonia than control (23.0 vs 15.9 mmol/l; P < 0.10) while ammonia in jejunum was not influenced by treatment. Iso-butyric acid in the jejunum was reduced by SB (-47%; P < 0.10). Interestingly, caecal iso-butyric acid was reduced by SB at 0.1% (-24%; P < 0.10) but increased by SB at 0.4% (+40%; P < 0.05). The other SCFA in jejunum and caecum were not affected by SB.

Sodium butyrate 0.4% 28.85 ± 2,64* 528 ± 53* 835 ± 97 1.58 ± 0.05
*Different from control by P < 0.10.
Conclusion: The present results show an improvement of animal growth when SB is fed at 0.4%. At the same time, SB at 0.4% increased caecal ammonia and iso-butyric acid concentrations, the both being metabolites resulting from bacterial proteolysis, but this effect was not observed when SB was fed at lower doses. Feeding SB to weaned pigs seems to have a positive effect on animal growth but further studies will be needed to better understand how SB influences animal performances and health.

Marsico, G., (2019). Overcoming Dichotomies. Transaction as a Core Issue in Educational Processes. In W-M., Roth, Transactional Psychology of Education. Toward a strong version of the social, Cultural Psychology of Education, 9, (pp.v-vii), Cham, CH: Springer;
No full textWhen Wolff-Michael Roth sent me the first proposal of this book Transactional Psychology of Education. Toward a strong version of the social I was positively surprised. Little time had passed since he had published his previous volume in my series, titled Understanding Educational Psychology (Roth & Jornet, 2016). He was again ready with another interesting editorial project. The book “smelled” good even before reading it. In fact, after reading few lines of the proposal, I was fully convinced of the relevance of Roth’s line of argumentation. There was something intriguing. Hereafter, the book went through all the long procedures of double-blind review, which allows this book series to be indexed in Scopus. Roth received many good feedbacks and some criticisms that helped him to develop his ideas even further.
The volume, eventually ready, kept the initial promise and offers the reader a refined synthesis of theoretical and empirical aspects of inquiry into education. Transactional Psychology of Education indeed combines the historical roots with the contemporary educational practice

The collection date for this lot is unknown, but it was catalogued at ANSP between 1915 and 1919 (P. Callomon, personal communication, January 2003). Alameda County: SBMNH 0 3696 (11), collector unknown; USNM 30484 (4), Oakland, A. W. Crawford coll.; USNM 30485 (3), Oakland, A. W. Crawford coll. The latter two lots are undated, but A. W. Crawford was a resident of Oakland and active as a mollusk collector around the 1870 's (Pilsbry 1939: 63; Hanna and Smith 1954; Pressley 1983). Distribution: Alameda and Contra Costa counties, central California, U.S.A. Diagnosis: A mediumsized, thinshelled, setose Vespericola with base of shell produced and somewhat excavated around umbilicus, inner quadrant of base with small shelf set off by spiral sulcus behind basal lip, inner part of basal lip angled forward, and dilation of inner end of lip weakly impinging on umbilicus. Description: Shell diameter 11.715.4 mm; height 7.810.3 mm; heightdiameter ratio 0.570.74. Shell thin. Periphery broadest at or just above middle of whorl; tightly rounded (sometimes with a trace of angulation, especially on early body whorl near aperture), convexly sloping toward base. Whorls 5.56.2. Coiling tightness 2.052.42. Spire conical; apical angle approximately 130 °; whorls of spire flattened; suture moderately impressed to strongly impressed. Embryonic whorls 1.51.75; smooth for first 0.2 whorl, thereafter with crowded, irregular, papillose, radiating rugae. Early postembryonic sculpture of retractive collabral striae and minute, overall granulation; granules axially elongated, closeset, parallel to growth striae, giving way after about third whorl to irregular collabral wrinkling. Spiral sculpture absent. Surface of periostracum radially wrinkled, pebbly to scaly on first four whorls, smoother on whorls 56. Periostracal setae present; borne in distinct rows, oblique to coiling direction; rows of setae descending at approximately 4045 ° with respect to whorl trajectory; density of setae 1220 per mm ². Setae on spire and shoulder of body whorl 0.20.4 mm long; curving away from direction of coiling to mostly askew, and readily lost by abrasion; bases of setae not conspicuously broadened or forked at base. Finlike, abapertural basal extensions of setae absent. Tips of setae not recurved. Setae on base about as long as those on spire; setation extending into umbilicus. Base of shell produced and somewhat excavated around umbilicus; inner quadrant of base with small shelf set off by spiral sulcus behind basal lip. Inner quadrant of base not spirally corrugated behind basal lip. Umbilicus of moderate width; contained 1320 times in diameter. Body whorl behind aperture not deflected downward prior to preapertural constriction. Last quarterturn (approximately) of body whorl not compressed apicobasally. Aperture broadly earshaped. Peristome in lateral view shallowly concave; at angle of approximately 30 degrees to shell axis. Lip turned outward and expanded above periphery, reflected below periphery; face of expanded lip concave; basal lip not markedly more thickened than rest of peristome; inner part of basal lip angled forward; inner end of lip scarcely dilated; dilation of inner end of lip covering from less than 10 % to 50 % of umbilicus. Parietal callus extending only slightly to left of columella in basal view; with shallow sinus below upper limb of peristome. Parietal lamella absent. Color of fresh shell not known, museum specimens yellowish brown; lip whitish. Dimensions of holotype: Diameter 14.5 mm; height 9.7 mm; 6.1 whorls Etymology: Ohlone, a culture of Native American people who inhabited the San Francisco Bay area prior to the arrival of Europeans (cf. Margolin 1978). Remarks: Vespericola ohlone, sp. nov., differs from Vespericola pilosus (Henderson, 1928) in having its base produced and somewhat excavated around the umbilicus rather than tumid and solidlooking. The inner quadrant of the base has a small shelf set off by a spiral sulcus behind the basal lip, not found in V. p i l o s u s. The inner part of the basal lip is angled forward toward the front of the umbilicus, whereas that of V. p i l o s u s is straight or gently curved forward (see Roth & Miller, 1993: 136, figs. 13). The new species differs from Vespericola marinensis Roth & Miller, 1993, in having its base produced and somewhat excavated around the umbilicus rather than tumid and solidlooking. The inner quadrant of the base has a small shelf set off by a spiral sulcus behind the basal lip, not found in V. marinensis. The inner part of the basal lip of V. m a r i n ensis is gently curved forward, rather than angled as in V. o h l o n e (see Roth & Miller, 1993: 140, figs. 1416). Vespericola armiger (Ancey, 1881), to which Cooper (1887) referred this species, differs in that its umbilicus is a minute, oblique perforation, nearly or completely covered by dilation of the inner lip; the inner end of the basal lip is briefly angled forward then angled backward over the umbilicus (see Pilsbry, 1940: 910, fig. 521 a). A parietal lamella is present in V. armiger but is absent in V. ohlone.Published as part of Roth, Barry, 2003, Polygyrid land snails, Vespericola (Gastropoda: Pulmonata), 4.

Redemption the life of Henry Roth
No full textHenry Roth (1906-1995), author of the great immigrant novel Call It Sleep, is one of the giants of American literature. After completing his first book in 1934, Roth lapsed into a legendary six-decade silence, only to reemerge with Mercy of a Rude Stream, hailed as "a landmark of the American literary century." In following Roth's tortured life from his childhood on the Jewish Lower East Side to his twilight years in New Mexico, literary critic Kellman has uncovered FBI files, spoken with family members and friends, and gained access to the tape in which Roth discussed the long-buried incest of his youth. Redemption is the saga of a great writer doomed to a life of psychological torment, but saved in the end by his search for deliverance.--From publisher description
Darstellung de Frau Bei Joseph Roth
No full textThe endeavor of this thesis is to throw light on the portrayal of women by the
Austrian-Jewish writer Joseph Roth. Roth’s women are regarded as highly negative and
thus the author has increasingly been judged a male chauvinist and misogynist. This
opinion seems particularly questionable since hardly any studies on his fictitious
women have ever been conducted. The present study aims at filling that void and
thereby presenting Roth’s views in a more differentiated manner. A new approach to
Roth is thus called for. The analysis draws from the socio-historic background in which
Roth’s work is situated. In his journalism as in his fiction, Roth strived to demonstrate
and deal with the challenges of the times he lived in. His work frequently revolves
around the “damaged” post-war generation in the 1920s and 30s, the feeling of being
literally and metaphorically homeless. His later works are mostly set in the past,
although this should not be viewed as escapism but as an attempt to come to terms
with present reality. The worlds he portrays are dominated by men who are neither
whole nor strong. But although women are few and it is said they are depicted only in
crude stereotypes, the study shows that Roth does address their problems and plights.
By observing women within established types, modern and traditional, it is revealed
that Roth indeed shows depth when characterizing women, and that his interest in
them is to use them as examples to illustrate fundamental aspects of the human
condition. Rather than portraying them subservient to man, Roth demonstrates their
common humanity. His understanding for the condition of women in his times often
becomes apparent only when the narrative perspective is isolated from the
protagonists. Simultaneously his work presents a valuable literary contribution for
Gender Studies.(D. Litt. et Phil.) (German)Classics and Modern European Language
