Stance-taking and participation framework in museum commenting platforms: On subjects, objects, authors, and principals

The realization of subjectivity through language use is a key concern of sociolinguistic research. We argue for examining it by juxtaposing Goffman’s participation framework and Du Bois’ stance triangle. We focus on museums’ commenting platforms as ‘stance-rich’ media (Du Bois 2007:151) by examining the communicative affordances of a visitor book at the Florida Holocaust Museum and analyzing museumgoers’ texts (3,064). These texts are homogeneous in their morally indignant evaluation of the Holocaust and their alignment with the museum, but heterogeneous in positioning and participation framework. Museumgoers’ texts are highly responsive to the setting and previous discourses of the museum and include patterns of shared authorship and principalship. These patterns allow museumgoers to construct shared, institutionally mandated, subjectivities while maintaining personal commitment. These findings contribute to our understanding of the construction of subjectivity as inherently dialogic, and as involving the purposeful use of a multiplicity of contextual resources. (Participation framework, stance triangle, repetitions, principalship, commitment, Holocaust, museums, visitor books) I N T R O D U C T I O N The construction, performance, and realization of subjectivity through language use is a key concern of sociolinguistic research. In the present study we aim at furthering our understanding of the practices and resources employed in these processes by juxtaposing two ubiquitous sociolinguistic concepts—participation and stance. Both concepts have proven to be compelling for examining the intricate ways in which events, contexts, relationships, and identities—indeed, social reality—are dynamically constructed and negotiated through language use. Studies informed by each of these concepts underscore the inherently dialogic and intersubjective nature of roles, attitudes, and utterances (C. Goodwin & M. Goodwin 2004; Kockelman 2004; Du Bois 2007).

THE NEED FOR UPPER BOUNDS ON SEISMIC GROUND MOTION

The usual representation of ground-motion variability using the unbounded lognormal distribution causes the hazard at very long return periods to be driven by uncertainty rather than physical parameters, which has led to extremely high ground-motion amplitudes in some important recent seismic hazard assessments. Therefore a truncation of the ground-motion probability distribution is required. To be meaningful, the definition of the truncation level has to be based on considerations related to the physical processes responsible for the bounded character of ground motion. Additional constraints on the form of the upper bound have to be included to allow a practical implementation.
Elucidation of the Mode of Action of a New Antibacterial Compound Active against Staphylococcus aureus and Pseudomonas aeruginosa

Nosocomial and community-acquired infections caused by multidrug resistant bacteria represent a major human health problem. Thus, there is an urgent need for the development of antibiotics with new modes of action. In this study, we investigated the antibacterial characteristics and mode of action of a new antimicrobial compound, SPI031 (N-alkylated 3, 6-dihalogenocarbazol 1-(sec-butylamino)-3-(3,6-dichloro-9H-carbazol-9-yl)propan-2-ol), which was previously identified in our group. This compound exhibits broad-spectrum antibacterial activity, including activity against the human pathogens Staphylococcus aureus and Pseudomonas aeruginosa. We found that SPI031 has rapid bactericidal activity (7-log reduction within 30 min at 4x MIC) and that the frequency of resistance development against SPI031 is low. To elucidate the mode of action of SPI031, we performed a macromolecular synthesis assay, which showed that SPI031 causes non-specific inhibition of macromolecular biosynthesis pathways. Liposome leakage and membrane permeability studies revealed that SPI031 rapidly exerts membrane damage, which is likely the primary cause of its antibacterial activity. These findings were supported by a mutational analysis of SPI031-resistant mutants, a transcriptome analysis and the identification of transposon mutants with altered sensitivity to the compound. In conclusion, our results show that SPI031 exerts its antimicrobial activity by causing membrane damage, making it an interesting starting point for the development of new antibacterial therapies.
Design research and the complexity encountered in people ’ s critical thoughts

This study focuses on the concept of “Critical Design”, which describes the development and use of design objects for the discussion of social and technological problem areas. “Critical Design” provokes or puzzles the consumer. Instead of offering people merely optimized and constraint action patterns, open situations and questions are created. The arising reactions provide valuable insights for innovative product development and basic design research. This paper assesses the potential of “Critical Design” approaches to be utilized as novel research tools for future challenges to design. The main contributions of this paper are threefold. Firstly, it reviews various ways of user engagement to design that reinterprets the conventional relationship of user and designer. Secondly, it selects and evaluates specific qualitative research methodologies that accept and support the active involvement of the researcher as well as the importance of letting theories "emerge" out of data, in order to develop a methodological research framework specific and original to design. Finally, the study offers an assessment of “Critical Design’s” potential, to understand and deal with people in a novel and richer way and to test it as a research tool that supports complex approaches. “Critical Design” illustrates the need for design researcher to deal with complexity encountered in the general dynamic of actors and in people's critical thinking.
A Risk-Scoring Feedback Model for Webpages and Web Users Based on Browsing Behavior

It has been claimed that many security breaches are often caused by vulnerable (naïve) employees within the organization [Ponemon Institute LLC 2015a]. Thus, the weakest link in security is often not the technology itself but rather the people who use it [Schneier 2003]. In this article, we propose a machine learning scheme for detecting risky webpages and risky browsing behavior, performed by naïve users in the organization. The scheme analyzes the interaction between two modules: one represents naïve users, while the other represents risky webpages. It implements a feedback loop between these modules such that if a webpage is exposed to a lot of traffic from risky users, its “risk score” increases, while in a similar manner, as the user is exposed to risky webpages (with a high “risk score”), his own “risk score” increases. The proposed scheme is tested on a real-world dataset of HTTP logs provided by a large American toolbar company. The results suggest that a feedback learning process involving webpages and users can improve the scoring accuracy and lead to the detection of unknown malicious webpages.
Laminar distribution of the cells of origin of the descending tectofugal pathways in the pigeon (Columba livia)

The horseradish peroxidase (HRP) technique was used to investigate the laminar distribution of the cell bodies of origin of the two major descending pathways from the avian tectum to the hindbrain, the crossed tectobulbar pathway (CTB) and the ipsilateral tectopontine‐tectoreticular pathway (ITP). The CTB, which projects to the contralateral paramedian reticular formation of the hindbrain, was found to arise mainly (80–95%) from the large multipolar neurons characteristic of layer 13 of the tectum. In addition, multipolar neurons of layers 14 and 15 of the dorsal tectum contribute to rostrally terminating portions of the CTB. Neurons of layers 11–12, particularly at rostroventral tectal levels, were also found to contribute to the CTB. The ITP, which projects to the ipsilateral lateral pontine nucleus and the overlying reticular formation, was found to arise chiefly from neurons of layers 9–10, 13, and 14–15, with some slight contributions from neurons of tectal layers 8, 11, and 12. Cells of layers 8–10 that contributed to the ITP tended to be of two general types: (1) small‐mediumsized fusiform neurons with vertically disposed processes, and (2) medium‐large‐sized multipolar neurons whose processes showed no consistent orientation from neuron to neuron. The lateral pontine nucleus apparently receives input from tectal layers 8–15 inclusive, while the reticular formation overlying the lateral pontine nucleus appears to receive input only from tectal layers 13–15. Injections of HRP into the CTB and ITP also resulted in labeled cells in subtectal sites within the optic lobe (nucleus intercollicularis and the lateral mesencephalic reticular formation).
Changes in Incidence and Survival of Ewing Sarcoma Patients Over the Past 3 Decades: Surveillance Epidemiology and End Results Data

Purpose The US population-based cancer registry Surveillance, Epidemiology, and End Results (SEER) database provides an opportunity to evaluate the incidence and survival rates of Ewing sarcoma (ES) for the past 3 decades. This analysis reflects trends for the diagnosis of localized versus metastatic disease and changes in ES survival in a setting of wide-ranging cancer care institutions across the United States, which is expected to be different from clinical trials published to date. Materials/Methods Data from the SEER public-access database were reviewed for the diagnosis of ES of the bone among patients of 1 to 19 years of age between 1973 and 2004. Age-adjusted incidence was analyzed for the entire group and for localized and metastatic disease separately over the past 3 decades. Actuarial survival rates were examined for 3 intervals: 1973 to 1982, 1983 to 1992, and 1993 to 2004. Results The overall incidence of ES seemed to remain unchanged with an average of 2.93 cases/1,000,000 reported annually between 1973 and 2004. The proportion of patients with distant metastasis among all ES cases remained in the 26% to 28% range, whereas the percent of localized cases slightly increased from 57% in 1973 to 1982 to 67% in 1993 to 2004 and the proportion of unstaged cases decreased from 17% to 5%. The 5-year survival of localized disease increased from 44% in the first study decade to 68% in the period after 1993, whereas 5-year survival of metastatic disease increased from 16% to 39%. The corresponding 10-year survival increased from 39% to 63% for localized disease and from 16% to 32% for metastatic ES. Conclusions The incidence of ES has not increased appreciably over the last 30 years. A marked decrease in the proportion of unstaged cases may be reflective of diagnostic improvement or changes in reporting. There is a clear improvement in survival for both localized and metastatic disease. Poorer outcome of metastatic patients still warrants intensification of therapy, which is currently being tested in several ongoing trials.
Prevalence and risk of gingival enlargement in patients treated with anticonvulsant drugs

Background Predictors of gingival enlargement in patients treated with anti‐epileptics have not been previously assessed. This study was conducted to determine, with the aid of two indices that score vertical and horizontal overgrowth, the prevalence and risk factors for gingival enlargement in patients treated with phenytoin and other anticonvulsant drugs.
Extraction of manganese ( II ) from acidic buffer medium using D 2 EHPA and Cyanex 272 as extractants

Extraction of Mn(II) from an acetic acid-acetate bu ffer medium was investigated using D2EHPA and Cyane x 272 in kerosene. The effect of different parameters such a s equilibrium pH, extractant concentrations, metal ion concentration, sodium acetate concentration and tem perature on the extraction system was studied. The percentage extraction of manganese was 96% with 0.1M D2EHPA co rresponding to equilibrium pH 4.52 whilst it was 76 % with 0.1M Cyanex 272 corresponding to equilibrium p H 4.86. Quantitative extraction of manganese was ac hieved with 0.8M D2EHPA. The loading capacities of both th e extractants were found out. On the basis of slope analysis results, the species extracted into the organic pha ses were proposed to be MnA 2.2HA and MnA2.4HA for both D2EHPA and Cyanex 272.When a ternary mixture contai ning 0.02M Mn(II), 0.01M Cu(II) and 0.01M Co(II) wa s extracted with D2EHPA, the order of extraction of metal ions is Mn(II)>Cu(II)>Co(II). Highest separa tion factors of 52.5(βMn⁄Cu) and 280.3( βMn⁄Co) was obtained from aqueous solution having pH 5.0 and extractant concentration of 0.05M D2EHPA in kerosene.
Rare Adnexal Tumor of the Breast: Poroid Hidradenoma

likely a multifactorial process, this Sampson’s theory is considered to be most widely accepted theory at present. Perhaps endometrial cells had seeded this patients’ umbilicus following her previous surgeries. Over 70% of cutaneous endometriosis is described secondary to prior surgeries and the surgeries appeared to be most commonly laparoscopic procedures. However, this secondary form of cutaneous endometriosis presented markedly late with no obvious stimulus. In addition, she did not present with typical symptoms of endometriosis, such as cyclical pain or bleeding. Postmenopausal endometriosis is typically found as a side effect of postmenopausal replacement hormone use. Paradoxically, our patient had been taking anastrozole (aromatase inhibitor) which blocks estrogen from being made. There have been several successful treatments with aromastase inhibitors but long-term responses have been variable. This suggests there is a complex multifactorial pathology underlying endometriosis, not yet completely understood. There have been case reports of malignant transformation in cutaneous endometriosis, particularly in patients with long-standing endometriosis. Hence, it is important to continue to follow-up this patient. Clear cell carcinoma is a common malignant differential, which can appear similarly. Such pathologies should be considered if presented with growing cutaneous abdominal masses. Histology is the key for diagnosis of benign cutaneous endometriosis.
Determination of Probability Distribution Function for Modelling Path Loss for Wireless Channels Applications over Micro-Cellular Environments of Ondo State , Southwestern Nigeria

In this research, the most appropriate probability distribution function for modelling RF signal path loss values in both wet and dry season months over urban, suburban and rural environments of Ondo State are presented. The data used consist of a drive test measurement campaign carried out in a typical urban, suburban and rural areas of Ondo State, South-western Nigeria in both wet and dry season months. The received signal strength (RSS) values were collected and recorded in log files alongside other environmental parameters using TEMS investigation tools. Path loss values were deduced from the measured RSS values. Some selected probability distribution function namely: gamma, lognormal, extreme value, logistic, Weibull and normal distributions function were fitted to the measured path loss values and the best suited one determined using three different metric measures. Results obtained show that normal distribution presents the best probability distribution curve for modelling the RF signal path loss over different micro-cellular environments of Ondo State. A typical result of the rural environment indicates that in wet season months, the normal distribution has RMSE of 7.060 dB, Relative Error of 12.480 % and R of 0.988, in dry season months, the RMSE is 9.060 dB, Relative Error of 13.450 % and R of 0.985. When compared with other distribution models, the same trend could be seen in other environments, although with different values of RMSE, Relative error and R. The mean and the standard deviation parameters for the normal distribution estimated, vary seasonal-wise and are environment dependent. However, the rural environment exhibited a wider seasonal variations when World Scientific News 118 (2019) 74-88 -75compared with the other environments. The results of this research is useful as a first-hand information in the planning of future wireless propagation channels in the studied environments.
Deep subsurface shear wave velocity investigation in south of Tehran , using large aperture ambient noise array measurement

SUMMERY The seismic hazard in southern part of Tehran is very high due to its vicinity to the active faults, in one hand and the high amplifying characteristics of local geological condition on the other hand. Beside these 2 factors the high density of housing and huge number of inhabitants in this part of the city resulted in very high seismic vulnerability and risk. The previous experimental studies, using weak motions and single station ambient noise recordings, revealed a very high amplification especially for low frequencies (0.31 Hz) despite to the existence of stiff to hard alluvial deposits near to the ground surface. The interpretation of this amplifying characteristic cannot be achieved without recognition of deep profile of the subsurface condition and the depth of the geological bedrock. This problem conducted us to perform a series of ambient noise array measurement with the aim of identification of deep shear wave velocity profile. The small aperture arrays, have been done in 2007 did not give us the satisfying results, so some large aperture arrays are tested. This paper discussed the results obtained by the large aperture measurements.
Clinical Characteristics of Gastrointestinal Lymphomas Associated with AIDS (GI-ARL) and the Impact of HAART

Abstract Purpose: The gastrointestinal (GI) tract is the most common site of extranodal disease in patients with systemic non-Hodgkin’s lymphoma (NHL). Patients with systemic NHL and GI involvement associated with AIDS (GI-ARL) have a significantly worse prognosis than those without AIDS. We studied whether the introduction of HAART is associated with improved survival in patients with GI-ARL. Patients and Method: 36 patients with GI-ARL were identified from the tumor registries of a large municipal hospital in New York City and a tertiary care facility in western New York State. Of these, 28 patients did not receive HAART and 8 were treated with HAART. The primary endpoint was survival, which was defined as time from date of diagnosis of NHL until death from any cause. Results: Patients were analyzed based on whether or not they were treated with HAART. Kaplan-Meier analysis showed significantly better survival in patients with GI-ARL who were concurrently treated with HAART (p = .014). Median survival was 5 months for the no-HAART group and 30 months for the HAART group. Conclusion: In patients with GI-ARL who were treated with chemotherapy, concurrent therapy with HAART therapy was associated with improved survival.
In-Line Rheological Measurements of Complex Model Fluids using an Ultrasound UVP-PD Based Method

In this work, a new in-line and non-invasive rheological instrument and measurement technique was evaluated and tested in an experimental flow-loop. The concept of the new rheometer is based on the Ultrasound Doppler Velocity Profile technique (UVP), in combination with a pressure difference method, (PD). Complex model fluids such as highly shear-thinning viscoelastic surfactant solutions, and non-Newtonian suspensions containing cellulose fibres or corn starch particles in a water or water-glucose matrix, were tested in the flow-loop. INTRODUCTION The rheological behaviour of the in general, non-Newtonian, highly concentrated and non-transparent fluids used in industry have so far been analysed using commercially available instruments, such as conventional rotational rheometers. Most of these commercially available instruments are usually not suitable for in-line rheological measurements and quality control as they are based on invasive methods, and have geometries that can affect and disturb the flow. Real flow situations can almost never be obtained using these instruments and they may also cause severe bio-safety problems due to contamination, which also limits their applicability in many situations. The research in the present study, continued the work made by Ouriev in a previous Ph.D project, using a modified experimental flow-loop at ETH – Institute of Food Science and Food Process Engineering in Zurich, Switzerland. The main objective of this research work was to expand and evaluate the UVP-PD methodology for non-invasive (no contact) rheological characterisation of nontransparent highly concentrated model fluids and shear thinning, viscoelastic, multiphase surfactant solutions. Aiming the adaptation of the UVP-PD method towards complex water-cellulose fibre suspensions introduced a new interesting field of application. UVP-PD IN-LINE MEASURING PRINCIPLES The principle of the Ultrasound Doppler Velocity Profile technique (UVP) is described extensively in previous work, e.g. by Takeda, and the combination with a pressure difference method, (PD) by Ouriev. Only a brief description of the method is given here. The rheological flow properties were derived from the simultaneous recording of the velocity profiles and the corresponding pressure drop within the pipe, using a new flow-adaptor with housing for an ultrasonic transducer and two pressure sensors. A schematic representation of the inline adaptor is given in figure 1.
Seismic robustness assessment of code compliant steel moment resisting frame under seismic triggered sequences of events

Earthquakes cannot be seen as isolated hazard events. High intensity earthquakes usually lead to secondary hazard events, such as fire, blasts, aftershocks and tsunamis, whose consequences have significant impact on life safety in post-mainshock risk scenarios. These secondary events that follow major earthquakes are not considered in codes. In this study, a probabilistic framework for evaluation of the structural safety under sequences of events is presented. After quantifying the structural safety, considering two specific seismic triggered sequences of events, and comparing it to that associated with the mainshock alone, a measure of the structural robustness to cascading events can be defined, independently of current life safety requirements present in codes. A newly designed steel frame building to be located in Lisbon, Portugal, is used as a case study. A nonlinear finite element model accounting for cyclic deterioration is developed in OpenSees. Code spectra compatible ground motions are used through spectrum matching of historical earthquake records using a wavelet-based transformation method.
