HeartBeat - An interactive installation to reflect the sentiments of Canadians during pandemics like Covid-19

Social media has given citizens an avenue to express their views on various subjects in their personal lives, policies, and even a way to communicate with each other about their sentiments and emotions. This is key during a pandemic such as Covid-19 where the world is facing a global impact and the need for a pandemic-related public art framework has been sought globally by art societies and researchers to revitalize the society. However, due to the pace of this pandemic, most city art strategy papers require a framework for pandemic related public art especially in Toronto which has an agenda of moving towards becoming a smart city and public art should reflect that. This thesis investigates how might public art installations reflect the sentiment of smart communities in a pandemic. I designed 'HeartBeat', an interactive installation and visualization to reflect the emotions of citizens during the pandemic using Research Through Design and user-centered design approaches. The goal is to reflect the sentiment of Canadians during the current pandemic. HeartBeat uses tweets from Canada and visualizes the popular emotion groups during the pandemic period in an interactive installation. To evaluate HeartBeat, I conducted case study evaluation for various time periods and semi-structured interviews by selecting experts such as artists, designers, curators, policymakers, and data journalists. The contributions from HeartBeat could provide designers and artists exploring the pandemic to consider these design choices and methodologies; discussion shows the ways available to understand emotions of citizens during a pandemic in a smart city; detailed process design and technology stack architecture for pandemic related public art which could be used as public art frameworks during pandemics

Ependymal tumors with oligodendroglioma like clear cells: Experience from a tertiary care hospital in Pakistan

Background: Ependymal tumors with oligodendroglioma like clear cells have never been reported from Pakistan. We aimed to see the features and outcomes of this rare entity.Methods: It was retrospective cohort conducted at the Department of Neurosurgery, Aga Khan University from 2003 to 2013. The medical records and radiology of patients with proven histopathology were reviewed. Analysis was done on SPSS 20.Results: Eleven cases of ependymal tumors with clear cells were found, which equated to 1.5% of the total tumor burden in 11 years. The median age was 49 years. Most common presenting symptom was headache 54.5%. Out of 11 patients, 9 patients had a supratentorial tumor. Magnetic resonance imaging showed hypointense signals on T1 and hyperintense signals on T2-weighted images in all cases. Contrast enhancement was found in 9 patients (77.8%), necrosis and hemorrhage was found in 4 (36%) and 3 (27%) patients, respectively. Immunohistochemistry showed glial fibrillary acidic protein and epithelial membrane antigen positivity in all cases. Ki-67 showed high proliferative index in 6 patients. According to the World Health Organization grading of ependymal tumors, 2 patients had Grade II tumors, and 9 patients had Grade III tumors with clear cells. Gross total resection was achieved in 6 (54.5%) and subtotal resection in 5 patients (45.4%). Recurrence was observed in 9 patients. Six patients died of the disease. Median progression-free survival and overall survival was 8 months and 10 months, respectively.Conclusion: Ependymal tumors with clear cells presented more commonly in Grade III lesions and were more aggressive in behavior with poorer outcome compared to similar studies

Carrot and Stick Approach: The Exploitative Leadership and Absenteeism in Education Sector

Utilizing the conservation of resources theory, this study investigates serial mediation of facades of conformity and depression between exploitative leadership and absenteeism. A total of 211 education sector employees using the convenient sampling technique took part in the survey with data collected in a time-lagged research design. Findings of the study reveal that facades of conformity and depression mediate the independent paths and play a serial mediating role between EL and absenteeism path. This study suggests that EL works as a workplace stressor, under which employees try to protect their valuable resources from further loss in the form of facades of conformity, in doing so, it leads to depression; thus, employees ultimately use absenteeism as an active coping strategy to cope with workplace stressors

Computational Seismic Analysis of Dry-Stack Block Masonry Wall

In this research the computational modeling of Dry-Stack Block Masonry (DSM) walls subjected to cyclic monotonic loading testing is done. The analytical results were compared with experimental test results of the unreinforced and unconfined DSM cantilever walls subjected to lateral loading along with a constant axial load. ABAQUS has been used for Finite Element Modeling and analysis of the wall. Various material properties are defined for the wall in the software and modeled as a homogeneous material. The proposed numerical models had a good correlation with the experimental data. The test results discussion includes failure moods, load displacement curves, and stress/strain profile. Doi: 10.28991/cej-2021-03091668 Full Text: PD

Organ preservation for advanced laryngeal cancer: Experience with concurrent chemoradiation therapy

Introduction: The larynx is a part of the upper respiratory tract that performs many essential functions including breathing, speaking, and swallowing. For this reason, the quality of life is significantly affected by laryngeal cancer and its treatment. Therefore, the focus of management for the last few decades has been on preserving the function of a larynx without compromising survival. This study was done with the purpose of reviewing our experience of organ preservation approach with concurrent chemoradiation therapy (CCRT) for locally advanced cancers of larynx.Methods: A retrospective chart review was carried out for the data of pathology reports and clinical notes of the patients who were diagnosed with laryngeal squamous cell carcinoma and primarily treated with CCRT at our tertiary care institute from November 2010 to June 2015.Results: Of 25 patients included in the study, there were 19 males and six females. The mean age was 56 years. On comparison of post-treatment CT scan following eight weeks of completion of therapy, 21 patients showed complete resolution of the disease and four patients had persistent disease who were later treated with salvage laryngectomy. The speech was understandable in 18 patients and poor or not understandable in seven patients. Three patients had chronic aspiration and breathing difficulties necessitating permanent tracheostomy. Three patients required permanent gastrostomy due to chronic dysphagia, one of them belonged to those who were also tracheostomized.Conclusions: Our experience with CCRT as an organ preservation approach for advanced laryngeal cancers was promising. When considering the functional organ preservation, the proportion of success is remarkably less; however, the overall impression is worthy enough to uphold the sentiment in favor of non-surgical organ preservation. The debate is ongoing in the quest of finding a balanced approach with acceptable toxicity and decent functional outcome with adequate speech, breathing, and swallowing

Optimizing Conservation of Nili Ravi Buffaloes in Southern Region of Khyber Pakhtunkhwa: A Comprehensive Evaluation of Phenotypic, Morphometric, and Productive Traits

In Pakistan, Nili Ravi buffalo is highly valued breed due to its high milk yield. Native to Punjab province, the breed is now extensively distributed throughout the country. To assess and optimize the conservation strategies for Nili Ravi buffaloes in southern Khyber Pakhtunkhwa by evaluating their phenotypic, morphometric, productive, and reproductive characteristics. Buffaloes were maintained at Livestock Research and Development Station in Paharpur, Dera Ismail Khan from 2010-2023, under breed conservation program. A sum of 298 records Nili Ravi buffaloes were used for the investigation. The research examined physical attributes such as coat color, horn morphology, and other qualitative characteristics. In addition to body weight, body length, withers height, chest circumference, and hip breadth, morphometric measurements were recorded. Mean body weight of Nili Ravi buffaloes was recorded was 677 + 213 Kg, produced 1387.12 + 32.87 liters milk during their lactation period of 292.87 + 32.40 days that was substantially impacted by year (p \u3c 0.05) and calving season. Calving interval was 480.18 + 22.09 days, whereas parity year and calving season bear considerable (p \u3c 0.05) impact on their characteristic. Dry period was 181.2 + 18.01 days. This research aided in the development of conservation and enhancement strategies for Nili Ravi buffalo in the region. Nili Ravi buffaloes in the region have excellent milk yield but the study disclosed morphometric variations within the breed, demonstrating the need for targeted breeding and management practices

Affective organizational commitment in global strategic partnerships: The role of individual-level microfoundations and social change

The roles and commitment of employees within global strategic partnerships are imperative to their success. Whilst previous studies have addressed certain individual-level microfoundations and social change in an interpretivist manner, this study first proposes a theoretical framework consists of individual-level microfoundations, social change and affective organizational commitment—interlinked with social identity theory. We then validate the 16-item scale for individual-level microfoundations and the 24-item scale for social change based on data collected from global strategic partnerships. For testing of our conceptualization, path modeling finally confirms significant relationships between the constructs. Our findings further present the partial mediating role of social change between individual-level microfoundations and affective organizational commitment. Therefore, the study provides a new pathway in advancing our understanding of global strategic partnerships. It also validates two new constructs directly relevant to managing global strategic partnerships. We discuss theoretical and practical implications of these linkages and contributions, and conclude by providing suggestions for future research

Idiopathic Perforated Intussusception in Adult – Case Report

Adult intussusception is typically less common as compared to paediatric population.  Adult intussusception makes 5% of all the cases of intestinal obstruction and it may be primary or secondary in nature. Mostly patients present with abdominal pain in emergency department. CT scan is the preferred diagnostic imaging modality. Unlike in the pediatric population, where conservative management is often attempted, surgical intervention with formal resection is the preferred treatment approach in adults with intussusception because of high incidence of some associated pathology. We present a case report of a middle-aged woman who presented with signs and symptoms of intestinal obstruction and was diagnosed with intussusception and peritonitis. Exploratory laparotomy and formal resection of the affected bowel segment with ileostomy was performed, and no underlying pathology was identified that makes this case an unusual one
