A dangerous but powerful idea - counter acceleration and speed with slowness and wholeness
No full textThe dangerous idea is that school reform, in India in particular, but across the world too, is impossible. Changing education, at the systemic level or at the institutional or school level, or educating teachers and school leaders in change can be classified as largely first order change - that of school improvement, which involves doing more of the same but doing it better (where the focus is on efficiency) and that of school re-structuring, which involves re-organising components and responsibilities (where the focus is on effectiveness). Geetha Narayanan is Principal Investigator with Project Vision at the Centre for Education Research Training and Development (CERTAD) within the Srishti School of Art Design and Technology in Bangalore, India. She has dedicated her career to finding and establishing new models of education that are creative, synergistic and original in their approach to learning.

Sexuality Beyond Consent: Risk, Race, Traumatophilia: A Conversation Among Artemis Christinaki, Amrita Narayanan, and Avgi Saketopoulou
No full textThis transcribed conversation of an online dialogue between Artemis Christinaki, Amrita Narayanan, and Avgi Saketopoulou introduces readers to Saketopoulou’s recently published book, Sexuality Beyond Consent: Risk, Race, Traumatophilia. With astute questions and through a series of probing observations, Christinaki and Narayanan engage the author, opening up crucial dimensions of psychoanalysis, gender and sexuality studies, and politics. The exchange tracks the three main signifiers of the book, risk, race, and traumatophilia, and articulates Saketopoulou’s critical concern with the traumatophobic logics rippling through the field. What emerges is a rich discussion of how Saketopoulou’s three terms work within psychoanalysis and the risks, opportunities, and challenges they unfurl in the clinic and in the broader field of psychosocial and psychoanalytic studies.<br/

Hypothermia due to limbic system involvement and longitudinal myelitis in a case of Japanese encephalitis: a case report from India
No full textSanthosh Narayanan,1 NK Thulaseedharan,1 Gomathy Subramaniam,2 Geetha Panarkandy,1 VK Shameer,1 Arathi Narayanan1 1Department of General Medicine, 2Department of Radiodiagnosis, Government Medical College, Kozhikode, Kerala, India Abstract: Japanese encephalitis (JE) is an infectious encephalitis prevalent in Asia. It usually presents with fever, headache, convulsions and extrapyramidal symptoms. Limbic system involvement and hypothermia though common in autoimmune encephalitis have never been reported in JE. We report a case of an 18-year-old girl with no previous comorbidities who presented to us with a history of fever and headache for 1 week duration. She developed bilateral lateral rectus palsy and asymmetric flaccid weakness of all four limbs, after 2 days of admission, which was followed by altered sensorium and intermittent hypothermia. Neuroimaging revealed longitudinal myelitis extending from pons till the L1 level along with bilateral thalamic hemorrhage in brain. Cerebrospinal fluid (CSF) was positive for IgM antibody to JE virus. She was treated with supportive measures, but she developed intractable hypothermia and seizures and succumbed to illness after 2 weeks of admission. Keywords: Japanese encephalitis, hypothermia, limbic syste
Cytomegalovirus retinitis occurring as a complication of HyperCVAD chemotherapy: Report of two cases
No full textCytomegalovirus (CMV) retinitis is usually diagnosed in patients with acquired immunodeficiency syndrome and in solid organ and hematopoietic stem cell transplant recipients. It produces a characteristic necrotizing retinitis which is a sight-threatening condition in these patients. CMV retinitis occurs rarely in patients undergoing only chemotherapy, and very few cases have been reported during the maintenance phase of acute lymphoblastic leukemia (ALL) in children. We report two patients, one with ALL and the other with Burkitt's lymphoma on HyperCVAD chemotherapy developing CMV retinitis during the course of treatment. Both patients were treated with intravenous ganciclovir, oral valganciclovir and intravitreal ganciclovir. Both patients are alive in remission at 60 and 40 months, respectively, with preservation of normal vision
Exploring image recognition: applying convoluted neural networks and learning to recognize safe cyclists
No full text"Today, there is a need to focus on the mobility revolution that is currently taking place. With the advent of more intelligent data gathering, there is also a growing need for using existing technology and infrastructure to achieve this goal, without incorporating expensive, complicated systems. As single-occupancy give way to shared mobility solutions, combined with regular mass transit and pedestrian-aware street infrastructure (traffic lights, crosswalks etc.), there is a large ""networked mobility system'' that has the potential to be tapped. Moreover, autonomous cars will be here soon, to add to the mix.
With statistics showing an increase in bicyclist related crashes over the last decade and an increase in bicycle-borne road users, there is a necessity for cities and autonomous vehicles to build bicycle safety into their adaptation to the ""driverless future"". This paper is an exploration into the use of a Convolutional Neural Network (CNN) based Machine Learning (ML) algorithm to identify bicycle-borne road users, who wear helmets.
We use a pre-made CNN framework-YOLO (You Only Look Once), and built around it further. After a brief proof-of-concept test on a publicly available dataset (including extraction, parsing and detection), the algorithm was modified. Some important features were added, such as identifying license plates, faces and encrypting them. Further, there is also a detailed account of using the ML capabilities that the framework is built with, and training it to identify bicycle-borne road users wearing a helmet."Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2019-08-01The student, Ramakrishnan Narayanan, accepted the attached license on 2017-07-21 at 13:17.The student, Ramakrishnan Narayanan, submitted this Thesis for approval on 2017-07-21 at 13:34.This Thesis was approved for publication on 2017-07-21 at 13:47.DSpace SAF Submission Ingestion Package generated from Vireo submission #11580 on 2018-03-02 at 13:03:11Made available in DSpace on 2018-03-02T20:02:40Z (GMT).

Elaborating the Project Management System
No full textThis chapter elaborates on the perspective of project management as an organizational capability, crucial for strategy execution and hence necessitating the attention of senior management. The author builds on the work on Project Management System (PMS) by Narayanan and DeFillippi, who developed the PMS concept to describe the context created for project managers by the senior management of a firm in response to strategy shifts. This chapter develops this concept further by detailing how PMS influences the conduct of project managers: their competencies, successful resource acquisition practices, ways to access information and knowledge, behavioral challenges, and career opportunities. The chapter also indicates some key practical implications for project managers: the need to be aware of the organizational context, understanding the strategic logic of projects, the need to speak the language of senior management, and mapping information networks. </jats:p
The "black evil" affecting patients with diabetes: a case of rhino orbito cerebral mucormycosis causing Garcin syndrome
No full textSanthosh Narayanan,1 Geetha Panarkandy,1 Gomathy Subramaniam,2 Chandni Radhakrishnan,1 NK Thulaseedharan,1 Neeraj Manikath,1 Sreejith Ramaswamy,1 Suma Radhakrishnan,3 Danish Ekkalayil1 1Department of General Medicine, 2Department of Radiodiagnosis, 3Department of Otorhinolaryngology, Government Medical College, Kozhikode, Kerala, India Abstract: Mucormycosis is a life-threatening infection affecting patients with diabetes. It is an angioinvasive disease often resistant to treatment with a debilitating course and high mortality. Here, we report a case of a 45 year old woman with type 2 diabetes mellitus who presented to us with history of right-sided ptosis and facial palsy, and subsequently developed loss of vision and palatal palsy. She was in diabetic ketoacidosis. Nervous system examination revealed involvement of right second, third, fourth, sixth, seventh, ninth, and tenth cranial nerves, suggestive of Garcin syndrome. The hard palate had been eroded with formation of black eschar. Computed tomography of paranasal sinuses revealed right maxillary and ethmoid sinusitis, with spread of inflammation to infratemporal fossa and parapharynygeal neck spaces. Debridement of sinus mucosa was done, and culture of the same yielded growth of rhizopus species. Histopathological examination of the tissue showed angioinvasion and fungal hyphae suggestive of mucormycosis. She was treated with amphotericin B, posaconazole, and periodic nasal sinus debridement, but her general condition worsened after 8 weeks due to secondary sepsis and she succumbed to death. Keywords: diabetes, rhinoorbitocerebral, mucormycosis, garcin syndrom
