Structural analysis in transit system using network theory case of Guadalajara, Mexico

Structural analysis in a transit network is a key aspect used to evaluate in a planning process. In this sense, the use of network science was applied in this work to generate a framework of the main structural features of a transport network. In this case, an alternative transport network in Guadalajara, Mexico was taken as an example. The network properties selected were grade of accessibility, spatial friction, and vulnerability. In the case of the grade of accessibility, this propriety makes reference to the efficiency of the travel time that the network gives due to its structural features. The spatial friction measures how direct in terms of distance the trips that the network provides are, and the vulnerability relates to the ease with which the network can comprise its performance by affectations to their nodes or links. In this sense, this work presents a detailed methodology and a set of open-source tools that can be used to measure these key structural elements for decision making.This research was funded by Mexican National Council for Science and Technology (CONACYT), grant number 641618.Peer ReviewedPostprint (published version

Evaluation of Health Information on the Web

There is a growing number of websites containing patient or consumer health information. The assumption is that patients should be able to become knowledgeable about their health conditions and become more involved in the management of their own health, but there are concerns about the validity of the information to be found on the Web. The goal of this research is to develop a system that evaluates websites containing educational information about Inflammatory Bowel Disease (IBD) to determine their quality and appropriateness for consumers. A small number of websites on IBD were evaluated manually by experts in the field. A number of different approaches based on machine learning algorithms evaluate websites as Excellent, Informative or Not Useful. Results of this approach are promising, but inconclusive as the dataset of websites for training and testing was not sufficiently large for any real conclusions to be made

ETIOLOGY, PATTERNS AND TREATMENT MODALITIES FOR MAXILLOFACIAL FRACTURES

Background: Over the years, the epidemiology of maxillofacial fractures keeps changing and new trends in etiology, pattern of presentation and management are constantly evolving. This, therefore, necessitates a constant appraisal of these fractures injuries in order to keep abreast with recent developments and changing pattern of their management. The aim of this study was to determine the frequency, etiology, patterns and different treatment modalities for maxillofacial fractures in patients treated at Lahore Medical and Dental College/Ghurki Trust Teaching Hospital (LMDC/GTTH). Methods: This cross sectional descriptive study was carried out at Lahore Medical and Dental College/Ghurki Trust Teaching Hospital (LMDC/GTTH) from February 2014 to October 2017.A total of 161 patients having maxillofacial fractures were included in the current study. Data on patients, including age, gender, cause of injury, fracture site, pattern and treatment modalities were collected and analyzed using SPSS version 20. Results: The age range was 3 to 62 (mean/SD, 26.42±11.24) with peak frequency occurring in age group 21-30 years. The male to female ratio was 5.2:1. The most common cause of maxillofacial fractures was road traffic accident (RTA) in 134 (83.23%) of patients, followed by in fall 12 (07.46%) and assault in 09 (05.59%) patients. The most frequent bone fractured was the mandible, which accounted for 117 (72.67%) cases and parasymphysis (43.22%) was the most frequent site affected, followed by 67 (41.61%) cases of zygomatic complex fracture and 56 (34.78%) cases of maxillary fractures. Open reduction and internal fixation (ORIF/ORIF with IMF) was performed in 127(78.88%) of patients while closed reduction and indirect fixation (IMF with eyelet wiring/arch bar elastics & splint fixation) was done in 34 (21.12%) of patients. Conclusion: As evidenced by the present study, majority of fractures were caused by RTA in 21-30 age group with male predominance. Mandible was the predominant fractured bone followed by the zygomatic complex area. ORIF was treatment of choice in the current study. According to present study, it seems reasonable to recommend that road traffic legislation enforcement and continuous public education towards the use of restraining devices and helmets should be encouraged by relevant authorities

Motivation and Attitude of BDS Students and House Officers in Their Postgraduate Career Selection

Objective: The objective of this research was to explore the motivational factors among BDS students and house officers for post graduate career selection. Study Design: Descriptive cross-sectional study. rd th Place and Duration of Study: The research was conducted from 3 October to 19 December 2022 at Lahore Medical and Dental College. Materials and Methods: A total of 226 participants (77 from third year BDS, 84 from 4 year BDS and 65 House Officers) were asked to fill a questionnaire in which the first part consisted of biodata and the second part was based on questions related to motivation of students for post-graduation and their preferred field of choice either clinical sciences or basic sciences. Descriptive statistical analysis was done and significance testing between the variables was done using chi-square test. Significance level was set at 0.05. Results: Results of the study showed a significant difference (p=0.018) between the groups in reasons for choosing dentistry as a profession where majority 51.3% were internally motivated. It was found that 61% students were motivated for post-graduation and majority (68.5%) wanted to choose clinical subjects as compared to 13.2% for basic sciences. There was significant difference between the groups (p=0.00) as a clear majority (71.6%) believed that there were not enough options for post-graduation in Pakistan and 85.3% wanted the institute to conduct seminars for career counselling (p=0.048). Conclusion: The dental students were motivated to do post-graduation out of which a clear majority opted to pursue clinical studies. The students wanted the institute to conduct career counselling sessions to help them plan their career choices

Forging connections: anthologies, arts collectives, and the politics of inclusion

The changing social and political landscape of twentieth-century Britain catalysed a remarkable rise in collaborative activity by artists and activists of black and Asian heritage. Creative communities began to gather in both local and regional contexts, with the aim of sharing resources and securing an audience. This chapter records some of these many activities, tracing the groups’ genesis, manifest objectives, and key contributions. It argues that anthologising should be understood as a specifically motivated activity. Literary anthologies of poetry and fiction served to showcase the diversity of contemporary writing, while also suggesting its coherence. Drawing on the concept of “strategic essentialism” elucidated by Gayatri Chakravorty Spivak, I show that the anthology acts to ensure the visibility of a group, bannered as a unified and singly-titled selection of texts, while also insisting on the differences within: the heterogeneous multiplicity of black and Asian British experiences and creative practices
