Writing to make a difference : discursive analysis of writer identity in research articles on management

Our purpose in this research is to quantitatively analyse how the communication of managerial knowledge is realised in research articles written by experienced writers for publication and those produced by graduate students as a course grade requirement. Specifically, we look at the ways these writers construct their authorial identities (textually conveyed in ‘voice’). To do so, we combine Hyland’s (2008) interactional model of voice with Lehman's (2018) and Lehman and Sułkowski's (2021) conceptualisation of ‘writer identity.’ The study results reveal important differences with regard to the expression of interaction in written discourse, with novices employing more interpersonal features to involve readers and experienced authors making linguistic choices to establish authority in their texts. We show that the use of interpersonal metadiscourse renders academic texts more accessible, reader engaging and interesting. This enables us to work towards the development of more effective writing instruction which is particularly relevant for English for Academic Purposes pedagogy

An unusual 'shovel-billed' dinosaur with trophic specializations from the early Campanian of Trans-Pecos Texas, and the ancestral hadrosaurian crest

We describe a new genus and species of hadrosaurid dinosaur, Aquilarhinus palimentus, from the lower shale member of the Aguja Formation (lower Campanian) of Big Bend National Park, south-western Texas. This species is characterized by several autapomorphies of the facial skeleton and mandible, including a crest composed of broadly arched nasals. Notably, the symphyseal processes of the dentary are elongated and reflected dorsally, causing the dentaries to meet with a 'W'-shaped anterior profile. A hypothesized shovel-shaped 'bill', associated with widening of the skull, in A. palimentus might have been used in shovelling out and scooping up semiaquatic vegetation. This animal is otherwise superficially similar to kritosaurins like Gryposaurus but differs in the retention of key plesiomorphic character states in the maxilla and jugal. Phylogenetic analysis reveals Aquilarhinus to be a non-saurolophid hadrosaurid allied to Latirhinus from the late Campanian of Mexico, which bears a similar broadly arched nasal. The recognition of this lineage adds to the diversity of non-saurolophid hadrosaurids and points to the existence of a hitherto unknown diversity of 'duck-billed' dinosaurs outside of the saurolophine-lambeosaurine radiation. Cranial crests were ancestral for early hadrosaurids and evolved before the saurolophid radiation. Ancestrally, crests were 'solid', and consisted of arched nasals. These were retained among kritosaurins and subsequently modified into the diverse crest morphologies observed among derived saurolophines. Lambeosaurine 'hollow-crested' crest morphology departed from the ancestral, 'solid-crested' pre-saurolophid condition early following the origin of that clade

Differential projections of the anterior and posterior regions of the medial amygdaloid nucleus in the syrian hamster

The medial nucleus of the amygdala is important for the neural control of reproductive behavior in the adult male Syrian hamster. Two types of signals are essential for this behavior, chemosensory stimuli and gonadal steroids; these signals appear to be received in different parts of the medial nucleus. The anterior region receives input from olfactory and vomeronasal systems, both of which are required for this behavior, whereas the posterior region receives gonadal hormone inputs. Behavioral studies have also suggested a functional differentiation of these two areas; electrolytic lesions of the anterior, but not the posterior, part eliminates normal sexual behavior. In this study, the efferent projections of the anterior and posterior divisions of the medial nucleus of the amygdala in the Syrian hamster were analyzed throughout the forebrain after injections of the anterograde neuronal tracer, Phaseolus vulgaris -leucoagglutinin. Neurons of the anterior, but not the posterior, medial nucleus, were found to project to numerous olfactory bulb projection areas and to the ventral striatopallidal complex. Within areas of the chemosensory circuitry that control reproductive behavior, the anterior region of the medial nucleus projects to the intermediate part of the posterior bed nucleus of the stria terminalis and the lateral part of the medial preoptic area, whereas the posterior region of the medial nucleus projects to the medial parts of these areas. Differences in targets were also observed in the ventromedial nucleus of the hypothalamus where the anterior region projects to the core while the posterior part projects to the shell of this nucleus. Furthermore, reciprocal projections between the anterior and posterior regions of the medial nucleus were observed. Taken together, these studies support the hypothesis that the anterior and posterior regions of the medial amygdaloid nucleus provide substantially different contributions to the control of reproductive behaviors.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/50051/1/903170208_ftp.pd

Avaliação das diferenças de gênero nas estratégias de enfrentamento da dor lombar

El dolor lumbar puede ser visto como un gran problema de salud pública. Las diferencias de género son importantes factores que influyen en los síntomas y en las respuestas del comportamiento. El objetivo de este estudio fue investigar las diferencias de género en los comportamientos de dolor y en el manejo del dolor lumbar crónico. La muestra estuvo conformada por 158 participantes (66,5% mujeres), con edades entre los 30 y 88 años que fueron diagnosticados con artrosis lumbar. Los instrumentos utilizados fueron: la Escala Visual Analógica, el Cuestionario de Calidad de Vida y un cuestionario para evaluar las actividades de ocio y distracción del dolor. Los resultados del MANOVA demostraron que las mujeres presentaron mayor percepción del dolor que los hombres. También fue posible observar frecuencias más altas de actividades sociales en las mujeres, así como correlaciones significativas entre las actividades sociales y los dominios psicológicos, sociales y medio ambientales. En conclusión, las mujeres presentan un mayor número de estrategias de afrontamiento para el dolor, lo cual puede influir positivamente en su calidad de vida.A dor lombar pode ser vista como um grande problema de saúde pública.

Gender differences are important factors that influence symptoms and behavioral responses. This research aimed to investigate gender differences in pain behaviors and pain management of chronic low back pain. The sample consisted of 158 participants (66.5% female), aged 30-88 who were diagnosed with Lumbar Osteoarthritis. The instruments used were the Visual Analogue Scale, the Quality of Life Questionnaire and a questionnaire to assess leisure and distraction activities from pain. Results of MANOVA showed that women have significant greater pain perception than men. Higher frequencies of social activities were also observed for women as well as significant correlations between social activities and psychological, social and environmental domains. In conclusion, women presented a greater number of coping strategies for pain than men, which probably tend to have a positive influence in their life quality

Pancreas divisum and duodenal diverticula as two causes of acute or chronic pancreatitis that should not be overlooked: a case report

<p>Abstract</p> <p>Introduction</p> <p>Pancreas divisum is a congenital anatomical anomaly characterized by the lack of fusion of the ventral and dorsal parts of the pancreas during the eighth week of fetal development. This condition is found in 5% to 14% of the general population. In pancreas divisum, the increased incidence of acute and chronic pancreatitis is caused by inadequate drainage of secretions from the body, tail and part of the pancreatic head through an orifice that is too small. The incidence of diverticula in the second part of the duodenum is found in approximately 20% of the population. Compression of the duodenal diverticula at the end of the common bile duct leads to the formation of biliary lithiasis (a principal cause of acute pancreatitis), pain associated with biliary lithiasis owing to compression of the common bile duct (at times with jaundice), and compression of the last part of Wirsung's duct or the hepatopancreatic ampulla (ampulla of Vater) that may lead to both acute and chronic pancreatitis.</p> <p>Case presentation</p> <p>We describe the radiological findings of the case of a 75-year-old man with recurrent acute pancreatitis due to a combination of pancreas divisum and duodenal diverticula.</p> <p>Conclusion</p> <p>Magnetic resonance cholangiopancreatography is advisable in patients with recurrent pancreatitis (both acute and chronic) since it is the most appropriate noninvasive treatment for the study of the pancreatic system (and the eventual presence of pancreas divisum) and the biliary systems (eventual presence of biliary microlithiasis). Moreover, it can lead to the diagnostic suspicion of duodenal diverticula, which can be confirmed through duodenography with X-ray or computed tomography scan with a radio-opaque contrast agent administered orally.</p

On Hilberg's Law and Its Links with Guiraud's Law

Hilberg (1990) supposed that finite-order excess entropy of a random human text is proportional to the square root of the text length. Assuming that Hilberg's hypothesis is true, we derive Guiraud's law, which states that the number of word types in a text is greater than proportional to the square root of the text length. Our derivation is based on some mathematical conjecture in coding theory and on several experiments suggesting that words can be defined approximately as the nonterminals of the shortest context-free grammar for the text. Such operational definition of words can be applied even to texts deprived of spaces, which do not allow for Mandelbrot's ``intermittent silence'' explanation of Zipf's and Guiraud's laws. In contrast to Mandelbrot's, our model assumes some probabilistic long-memory effects in human narration and might be capable of explaining Menzerath's law.Comment: To appear in Journal of Quantitative Linguistic
