A study of nonlocal fractional neutral stochastic integrodifferential inclusions of order 1<α<21<\alpha<2 with impulses

This paper considers a class of nonlocal fractional neutral stochastic integrodifferential inclusions of order $1<\alpha<2$ with impulses in a Hilbert space. We study the existence of the mild solution for the cases when the multi-valued map has convex and non-convex values. The results are obtained by combining fixed-point theorems with the fractional order cosine family, semigroup theory, and stochastic techniques. A new set of sufficient conditions is developed to demonstrate the approximate controllability of the system. Finally, an example is given to illustrate the obtained results

Optimal controllability for multi-term time-fractional stochastic systems with non-instantaneous impulses

In the present paper, we study the existence and optimal controllability of a multi-term time-fractional stochastic system with non-instantaneous impulses. Using semigroup theory, stochastic analysis theory, and Krasnoselskii's fixed point theorem, we first establish the existence of a mild solution. Further, we obtain that there exists an optimal state-control pair of the system. Some examples are given to illustrate the abstract results

Prevalence Of Parafunctional Habits And Temporomandibular Disorder Symptoms In Young Individuals Reporting To Watim Dental Hospital

Objective: This study aims to identify the prevalence of parafunctional habits and common symptoms of temporomandibular disorders in young individuals reporting to the Watim Dental College Materials and methods: This cross-sectional study was carried out by a survey and clinical examination over a period of six months from September 2021 to February 2022. Data from 103 patients, who fulfilled the inclusion criteria, were collected using a structured questionnaire and clinical examination regarding their parafunctional habits and temporomandibular joint symptoms. Informed consent was filled out by all the participants. Data were analyzed using SPSS version 23. A descriptive analysis was calculated for both quantitative and qualitative variables. Results: The prevalence of oral parafunctional habits among the study sample was quantified on a binary scale (yes/no) where nail-biting was observed to be highly prevalent (38%), followed by mouth breathing (27%). The most frequently reported temporomandibular joint symptom was noise (clicking or crepitation)  which was 66%. Difficulty in mouth opening was the least common (20%) of all the symptoms noted. Conclusion: It may be concluded from our study that amongst parafunctional habits nail biting is the most common habit amongst young individuals and amongst the temporomandibular joint disorder clicking and crepitation is the most common symptom persistent with the condition. Keywords: clicking, nail-biting, parafunctional habits, temporomandibular joint symptom

A study of nonlocal fractional delay differential equations with hemivariational inequality

In this paper, we study an abstract system of fractional delay differential equations of order 1 < q < 2 with a hemivariational inequality in Banach spaces. To establish the existence of a solution to the abstract inequality, we employ the Rothe technique in conjunction with the surjectivity of multivalued pseudomonotone operators and features of the Clarke generalized gradient. Further, to show the existence of the fractional differential equation, we use the fractional cosine family and fixed point theorem. Finally, we include an example to elaborate the effectiveness of the findings

Transcultural identity and Bangla heritage language teaching

The new waves of immigrants in Canada have exciting linguistic resources that need to be harnessed for personal, professional, and national interests. While prior studies have investigated the opportunities and challenges of heritage language (HL) community programs, few have explored the negotiation of transcultural identity in HL teaching, particularly with reference to the growing Bangladeshi community. Drawing on a two-year qualitative case study from September 2020 to December 2022, at the community-based Vancouver Bangla School (VBS), this research sought to address this gap by investigating a broad research question: How did Bangla HL teachers navigate their transcultural identity to promote student investment in the learning of Bangla? The study conceptualizes HL teachers’ transcultural identity using four key constructs: identity and investment (Darvin & Norton, 2015), translingual practices (Garcia & Li Wei, 2014), multimodal practices (Kress, 2014), and emotion labor (Benesch & Prior, 2023). The broad research question gave rise to three central research questions: (i) What is the identity of the Bangla HL teacher? (ii) How did VBS teachers leverage show-and-tell tasks to promote student investment in online Bangla HL learning? and (iii) How did volunteer teachers navigate emotion labor, identity, and investment in Bangla HL teaching? Data sources included participant classroom observations, field notes, interviews, a focus group discussion, questionnaires, and educational resources, which were analyzed using thematic analysis. Seven volunteer teachers participated in the study. Findings indicate that teachers were deeply invested in promoting Bangla as a mother tongue in multicultural Canada, with a strong ideological belief in the importance of HL maintenance for cultural continuity. They also embraced the transcultural relationship between Bangladeshi and Canadian culture. Teachers leveraged students’ translingual and multimodal resources using innovative activities like show-and-tell tasks to help students negotiate their transcultural identities. Teachers’ investment in promoting students’ transcultural identities was powerful, enabling them to navigate and manage the emotion labor associated with volunteer teaching and limited resources. The study found that the conceptualization of transcultural identity resists binaries and embraces hybridity. The research contributes to a growing body of literature exploring the complexity of teacher identity and transculturalism in heritage language education.Education, Faculty ofLanguage and Literacy Education (LLED), Department ofGraduat

Bangla and the identity of the heritage language teacher

Research on language teacher identity in the field of heritage language (HL) teaching has received little attention, although identity is a central concern in HL education. Our research seeks to address this gap in the research on language teacher identity. Drawing on the Darvin and Norton’s (2015) conceptual framework of identity and investment, we investigate the extent to which Bangla HL teachers are invested in teaching Bangla, and how their investment provides insight into their identity as heritage language teachers. The study was conducted at the community-based Vancouver Bangla School, and the data, which focuses on our focal participant, Mili, were drawn from a year-long qualitative case study. Data sources include participant classroom observations, field notes, interview transcripts, a questionnaire, and educational resources used in the class, which were analyzed using thematic analysis. Findings indicate that Mili’s investment in teaching Bangla was deeply rooted in her ideological belief in the importance of HL maintenance for cultural continuity. However, she was also interested in the transcultural relationship between Bangla and English, and between Bangladeshi culture and Canadian culture. Her investment in teaching Bangla as a heritage language suggests that an HL teacher may serve as a cultural mentor, collaborator, innovator, and active community member. As a member of both the Canadian and Bangladeshi cultural community, she valued students’ Canadian cultural practices and helped students in negotiating their new transcultural identities as Bangladeshi-Canadians. Our study suggests that the identity of the HL teacher could be expressed as a transcultural identity that resists binaries and embraces hybridity.Education, Faculty ofLanguage and Literacy Education (LLED), Department ofReviewedOpen access funding provided by the UBC Open Access Fund for Humanities and Social Sciences Research.FacultyGraduat

Our Multilingual Village Symposium and Storybooks Canada Public Launch November 2, 2018

The symposium on “Our multilingual village: Supporting refugee children and families in BC” and the public launch of Storybooks Canada (storybookscanada.ca) were held on November 2, 2018, at the University of British Columbia (UBC), Vancouver, Canada. The event was organized by Dr. Janet Jamieson (EPSE & CECER) and Dr. Bonny Norton (LLED).This event gathered an interdisciplinary group of professionals, including academics, researchers, administrators, practitioners, and policy-makers working to support refugee and immigrant children and families in BC. This report summarizes and documents the important conversations of the refugee symposium (35 participants) and the public launch (over 100 participants) to promote ongoing discussion and connection. It is hoped that this report will be useful for scholars, educators, students, researchers, and policymakers interested in supporting immigrant and refugee children and families.

Effect of nutritional status on wound healing after coronary artery bypass graft (CABG) surgery

Objective: To assess the pre-operative nutritional status and its effect on wound healing of patients having undergone coronary artery bypass graft surgery. Method: The hospital-based prospective study was conducted at the Armed Forces Institute of Cardiology/National Institute of Heart Disease, Rawalpindi, Pakistan, from October 2017 to March 2018, and comprised patients who underwent coronary artery bypass graft surgery. Sternal wound healing as an outcome measure was assessed with nutritional status. Investigation of dietary data focussed on various food groups and their impact on wound healing. Data was analysed using SPSS 21. Results: Of the 330 patients, 16 (4.8%) died within hospital. The final sample, as such, comprised 314(95.2%) patients; 273 (86.9%) males and 42 (13.1%) females, with an overall mean age of 56.6±8.3 years. The mean body mass index was 26.9±4.3kg/m². There was non-significant relationship between body mass index and wound healing (p>0.05). Significant relationship was observed between albumin, blood glucose and wound healing (p<0.05). Conclusion: Low levels of albumin and poor blood glucose control before surgery was found to be associated with delayed wound healing. Nutritional intervention prior to coronary artery bypass graft surgery may lead to reduced risk and complications during / after surgery

Efficacy of Flaxseed and Fish Oils on Adults with Rheumatoid Arthritis

Objective: To assess the relative efficacy of flaxseed and fish oils in the management of rheumatoid arthritis. Methods: The comparative study was conducted in the outpatient department of Rheumatology at Fatima Memorial Hospital, Shadman, Lahore, Pakistan, from July to December 2017, and comprised rheumatoid arthritis patients who were divided into group A receiving 3g/day of flaxseed oil and group B receiving 3g/day of fish oil for 90 days. Blood samples were taken at baseline and post-intervention to note the difference on biochemical parameters. Data was analysed using SPSS 21. Results: Of the 60 patients, there were 30(50%) in each of the two groups. Overall, there were 8(13.3%) males and 52(86.7%) females. Both groups showed significant change in all biochemical parameters compared to baseline values (p<0.05). Intergroup comparison showed that flaxseed oil treatment was significantly more effective than fish oil treatment (p<0.05). Conclusion: While both forms of intervention were found to be effective, flaxseed oil was significantly more effective than fish oil in reducing the inflammation of joints in rheumatoid arthritis patients.
