    Genre Taxonomy: A Knowledge Repository of Communicative Actions

    In this paper, we propose a genre taxonomy as a knowledge repository of communicative structures or "typified actions" enacted by organizational members. The Genre taxonomy aims at helping people to make sense of diverse types of communicative actions, and has three features to achieve this objective. First, the genre taxonomy represents the elements of both genres and genre systems, sequences of interrelated genres, as embedded in a social context considering the "5W1H" questions (Why, What, Who/Whom, When, Where, and How). In other words, the genre taxonomy represents the elements of both genres and genre systems in terms of purpose, contents, participants, timing of use, place of communicative action, and form including media, structuring devices and linguistic elements. Second, the genre taxonomy represents both widely recognized genres such as a report and specific genres such as a technical report used in a specific company, because the difference between a widely recognized genre and a specific variant based on the more general genre sheds light on the context of genre use. Third, the genre taxonomy represents use and evolution of genre over time to help people to understand how a genre is relevant to a community where the genre is enacted and changed. We have constructed a prototype of such a genre taxonomy using the Process Handbook, a process knowledge repository developed at MIT. We have included both widely recognized genres such as the memo and specific genres such as those used in the Process Handbook itself. We suggest that this genre taxonomy may be useful in the innovation of new document templates or methods for communication because it helps to clarify different possible uses of similar genres and explicates how genres play a coordination role among people and between people and their tasks.

    We demonstrate that the parafermions appear in the rr-th root of unity limit of qq-Virasoro/WnW_n algebra. The proper value of the central charge of the coset model sl^(n)rsl^(n)mnsl^(n)mn+r \frac{\widehat{\mathfrak{sl}}(n)_r \oplus \widehat{\mathfrak{sl}}(n)_{m-n}}{\widehat{\mathfrak{sl}}(n)_{m-n+r}} is given from the parafermion construction of the block in the limit.Comment: 13 pages, 1 figure; v2: references added, minor corrections mad

    A-D hypersurface of su(n)su(n) N=2\mathcal{N}=2 supersymmetric gauge theory with Nf=2n2N_f = 2n-2 flavors

    In the previous letter, arXiv:2210.16738[hep-th], we found a set of flavor mass relations as constraints that the β\beta-deformed An1A_{n-1} quiver matrix model restores the maximal symmetry in the massive scaling limit and reported the existence of Argyres-Douglas critical hypersurface. In this letter, we derive the concrete conditions on moduli parameters which maximally degenerates the Seiberg-Witten curve while maintaining the flavor mass relations. These conditions define the A-D hypersurface.Comment: 6 page

    Arginine Vasopressin-Independent Mechanism of Impaired Water Excretion in a Patient with Sarcoidosis Complicated by Central Diabetes Insipidus and Glucocorticoid Deficiency

    A 28-year-old man was admitted to our hospital because of reduced livido and increased fatigability. Four months before admission, he noticed polyuria, which was gradually relieved by admission. Magnetic resonance imaging revealed enhancing lesion centrally in the pituitary stalk. Biopsy from the skin revealed noncaseating granuloma composed of epithelioid cells, and a diagnosis of sarcoidosis was made. Although plasma arginine vasopressin (AVP) was undetectable after administration of hypertonic saline, urinary output was within normal range (1.5 to 2.2 L/day). The urine osmolality became above plasma levels during the hypertonic saline test. Hormonal provocative tests revealed partial glucocorticoid deficiency. Soon after the glucocorticoid therapy was begun, moderate polyuria (from 3.5–4.0 liters daily) occurred. At this time, plasma AVP was undetectable, and urine osmolality was consistently below plasma levels during the hypertonic saline test. In conclusion, we showed in human study that masked diabetes insipidus could be mediated by AVP-independent mechanisms

    Assessing patterns of T2/T1rho change in grade 1 cartilage lesions of the distal femur using an angle/layer dependent approach.

    PURPOSE:To assess changes in the patterns of T2 and T1rho values within grade 1 cartilage lesions of osteoarthritis (OA) patients compared to healthy controls. MATERIALS AND METHODS:Twenty healthy knees and 25 OA knees were examined on a 3 T scanner. Areas of signal heterogeneity within the cartilage of the distal femur were identified using fat suppressed proton density-weighted imagines. T2 and T1rho values in each OA patient with grade 1 lesions were compared to average T2 and T1rho values of the corresponding areas in healthy subjects. RESULTS:A total of 28 areas including grade 1 lesion were identified. Compared to normal cartilage, the majority of grade 1 cartilage lesions demonstrated either no significant change or a statistically significant increase in both T2 values (18/28, 64%) and T1rho values (23/28, 82%). Compared to T2, T1rho demonstrated a greater proportion of statistically significantly higher values in OA patients than those from the normal controls. However, T2 and T1rho values in grade 1 lesions can be decreased, or demonstrate mixed patterns compared to those in healthy cartilage. CONCLUSION:Our results suggest that early degenerative cartilage lesions can demonstrate various patterns of T2 and T1rho changes
