    Sensemaking handoff: When and how?

    Full text link
    Computer support helpdesks often engage in sensemaking while working on atypical problems. Handoffs are common in these sensemaking situations due to shift changes, because a different skill or perspective is needed or simply because the current sensemaker may be exhausted. Though handoff may be needed, it may not always be successful. This could be true because sensemaking involves non-routine activities for which no structural support for handoff may exist, or because sensemakers may not be sure what to handoff if sensemaking is not complete. This study examined the issues related to sensemaking handoff in computer support helpdesks. Existing theories of sensemaking (Russell et al, 1993 and Weick, 1996 ) were used as a framework. Semi-structured interviews were conducted with two different computer helpdesk personnel groups at a large mid-western university. Successful handoffs occurred either very early or very late in the sensemaking process. This choice of handoff time as well as other aspects of handoffs are discussed using the principles of least collaborative effort [13] and mindfulness [18].Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/63060/1/1450450234_ftp.pd

    Artifact usefulness and usage in sensemaking handoffs

    Full text link
    The complexities of sensemaking suggest that collaboration should be difficult, requiring a rich ecology of collaboration support. This can be a problem for handoff sensemaking, where one person must continue where another has left off, sometimes with only material artifacts as the basis of the handoff. A detailed analysis of essential attributes of sensemaking tasks, and elements identified in the computer supported collaborative work literature were combined to yield insight into handoff sensemaking and guide empirical work. A lab-study showed that handoffs relying only on artifacts from previous sensemaking could be successful. The lab studies also indicated timing and quality affects on the sensemaking handoffs, with different quality materials used differently, and early efforts possibly being particularly difficult to hand off. Design of support for sensemaking handoffs will have to take such effects into account.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/78323/1/1450460219_ftp.pd

    Background: Assessment of the tear film is necessary in routine clinical practice because an unstable tear film can hamper the quality of life by causing vision-related problems and compromising the ocular surface. One of the major concerns related to an unstable tear film is dry eye. Many of dry eye patients suffer from a lack of meibum which forms the lipid layer of the tear film. The lipid layer can be graded and interpreted by using interferometry. However, interpretation and grading of this dynamic layer may be inconsistent in terms of inter- and intra- observations. This study investigated the difficulty of consistent, subjective grading of clinical findings, in general.Methods: The interferometry images of 30 subjects captured from different equipment were analyzed subjectively. The agreement between intra-observer repeatability was also measured.Results: A positive Spearman’s correlation of 0.81 was found among different grading patterns observed using the Tearsope to compare right and left eyes. Similarly, a positive Spearman’s correlation of 0.63 was found among different grading patterns observed under interferometer in right and left eye. Correlations were statistically significant, p<0.001. The agreement between intra-observer repeatability calculated using Cohen’s kappa values were also statistically significant, p<0.001.Conclusions: A correlation between the findings of different equipment could not be made due to the differences in wavelengths of incident light and the image details. However, a new grading pattern has been proposed to describe the thickness of various lipid layer patterns observed under Doane’s interferometer

    AbstractAimSpontaneous coronary artery dissection (SCAD) is a less recognized cause of ST elevation myocardial infarction (STEMI) in clinical practice. The aim of this communication is to describe a case series in South Asian population and highlight on the long-term clinical outcomes on conservative management.MethodsA retrospective analysis of data of five patients (6 instances) of SCAD managed in a tertiary care center during January 1994 to June 2015 was done. Clinical, angiographic, therapeutic, and follow-up data till end of June 2015 are analyzed.ResultsAll patients were young (mean – 33 years) and predominantly male. Etiology of SCAD was diverse and included peripartum state, vigorous activity and atherosclerosis. Left anterior descending (LAD) coronary artery was predominantly involved and the majority had angiographic type 1 SCAD. Medical treatment provides excellent long-term benefits. Coronary stenting provided symptomatic benefit in a patient with favorable anatomy.ConclusionsClinical recognition of SCAD is difficult. It should be suspected in peripartum state, young females and in presence of other precipitating factors. Coronary angiography is essential for establishing the diagnosis. Medical treatment provides favorable long-term survival.Implications and practiceThe awareness of SCAD is important for all clinicians involved in STEMI care. A prompt suspicion can avoid administration of thrombolytic therapy. Early coronary angiography will provide an accurate diagnosis and help in deciding appropriate therapy. Percutaneous intervention can be challenging

    Overcoming Barriers to Skill Injection in Language Modeling: Case Study in Arithmetic

    Full text link
    Through their transfer learning abilities, highly-parameterized large pre-trained language models have dominated the NLP landscape for a multitude of downstream language tasks. Though linguistically proficient, the inability of these models to incorporate the learning of non-linguistic entities (numerals and arithmetic reasoning) limits their usage for tasks that require numeric comprehension or strict mathematical reasoning. However, as we illustrate in this paper, building a general purpose language model that also happens to be proficient in mathematical reasoning is not as straight-forward as training it on a numeric dataset. In this work, we develop a novel framework that enables language models to be mathematically proficient while retaining their linguistic prowess. Specifically, we offer information-theoretic interventions to overcome the catastrophic forgetting of linguistic skills that occurs while injecting non-linguistic skills into language models.Comment: NeurIPS 2022: Math-AI Worksho

    A biometric system is used for recognition of individual based on their physical or personal characteristics. Biometric system includes face recognition, fingerprint recognition, voice recognition , the Iris recognition etc. various study has shown that iris recognition is the most efficient biometrics. hence the work presented here involved designing a user friendly GUI based efficient and optimal iris recognition system using MATLAB® GUI. So that one with least knowledge of technology can use it. in order to generate the base templates of iris, we have used Masek and Kovesi’s algorithm with some necessary changes. We have used the Image processing toolbox and GUIDE toolbox of MATLAB, to make the GUI for iris recognition system. There are so many methods to design an Iris recognition system having their own pros and cons. Some methods are calculation intensive but they lead in performance while other are less calculation intensive but they lack in performance. To design the iris recognition system we have focused on both the sides i.e. calculation intensity and performance, to make the system efficient and optimal. In order to use this GUI based iris recognition system first, one need to just select an input eye image that one want to recognize from the iris image database and then just click on recognize button in GUI. now you are done. After the recognition process is complete it shows all the results related to that particular recognition process. like the name or number of the recognized person, segmented eye image, noise template etc and MATLAB’s output window shows the hamming distance related to the matching process of the recognition system. We have used the IIT Delhi’s iris image dataset for the verification and testing of our GUI based iris recognition system. DOI: 10.17762/ijritcc2321-8169.150512

Usage and distribution for commercial purposes as well as any distribution of modified material requires written permission.We report a case of prostatic lymphoma of the Walden-ström's macroglobulinemia subtype in a 64-year-old gentleman who underwent a robotic-assisted laparoscopic prostatectomy following lower urinary tract symptoms and high grade adenocarcinoma on transperineal prostate biopsy's. Histopathological and immunohistochemistry analysis at the time of surgery was consistent with a CD5-negative small B-cell lymphoma. To our knowledge this is the first reported prostatic lymphoma identified following robotic-assisted laparoscopic prostatectomy and the first documented case of lymphoplasmacytic lymphoma involving prostate. Lymphoma of the prostate is an uncommon entity in surgical practice and their diagnosis often poses considerable difficulty as they often mimic carcinoma. We discuss this rare diagnosis and review the literature for current considerations and prognosis.Peer reviewedFinal Published versio
