Transforming Curriculums For An Age Of Multi-Modal Education: A 5-Phase Approach

The pandemic has accelerated the trend towards online and hybrid learning with many educational institutes pivoting their education to online learning environments and has subsequently transformed societal expectations. There have been many benefits associated with these changes (e.g., multi-dimensional interactions, flexibility and deep learning). As we move into more online education due to changing needs and demands from students, how best to adapt our education for multi-modal learning environments can be a challenge. Getting our education ready for a multi-modal age is bringing about disruptive changes forcing us to rethink what we teach and how we teach it. Thus, the objective of this paper is to present a framework that will allow for the evaluation of curriculums and enable educators to create sustainable, flexible educational environments relevant for multimodal learning environments while remaining at the forefront of educational needs. In this paper, we present the 5-phase approach that we used to assess our programme and redesign our curriculum. The five phases include: Inventory, Analysis, Evaluation, Design and Implementation. We will present the highlights from our experience and the challenges we have had to overcome. The framework that we present is applicable to different computer science, spatial and data engineering programmes that require a mix of theoretical and hands-on practicals

Tweeting and Tornadoes

ABSTRACT Social Media and micro-blogging is being used during crisis events to provide live up-to-date information as events evolve (before, during and after). Messages are posted by citizens or public officials. To understand the effectiveness of these messages, we examined the content of geo-located Twitter messages ("tweets") sent during the Moore, Oklahoma tornado of May 20 th , 2013 (+/-1day) to explore the spatial and temporal relationships of real-time reactions of the general public. We found a clear transition of topics during each stage of the tornado event. Twitter was useful for posting and retrieving updates, reconstructing the sequence of events as well as capturing people's reactions leading up to, during and after the tornado. A long-term goal for the research reported here is to provide insights to forecasters and emergency response personnel concerning the impact of warnings and other advisory messages

Downscaling reveals diverse effects of anthropogenic climate warming on the potential for local environments to support malaria transmission

The potential impact of climate warming on patterns of malaria transmission has been the subject of keen scientific and policy debate. Standard climate models (GCMs) characterize climate change at relatively coarse spatial and temporal scales. However, malaria parasites and the mosquito vectors respond to diurnal variations in conditions at very local scales. Here we bridge this gap by downscaling a series of GCMs to provide high-resolution temperature data for four different sites and show that although outputs from both the GCM and the downscaled models predict diverse but qualitatively similar effects of warming on the potential for adult mosquitoes to transmit malaria, the predicted magnitude of change differs markedly between the different model approaches. Raw GCM model outputs underestimate the effects of climate warming at both hot (3-fold) and cold (8-12 fold) extremes, and overestimate (3-fold) the change under intermediate conditions. Thus, downscaling could add important insights to the standard application of coarse-scale GCMs for biophysical processes driven strongly by local microclimatic conditions.</p

PAPERS OF PRACTICE, TECHNICAL REPORTS AND INDUSTRY NOTES Improving Cadastre: Development of a Workflow Prototype Utilizing ESRI’s Parcel Fabric

Abstract: The Rapid City/Pennington County, South Dakota, GIS Division has continuously maintained a parcel dataset that was originally created in 1989. Advances in technology and the desire to expand the use of land-based information, requiring highly accurate data, highlighted the need to improve the cadastre. Technical obstacles, such as incorporating and maintaining survey information as well as easily updating related layers, previously hindered this effort. The Environmental Systems Research Institute (ESRI) parcel fabric data model purports to have resolved many of these issues and was the focus of this project. A workflow was developed and an accuracy assessment performed during this study to test these claims. The project successfully addressed the following key factors: (1) conversion of the existing data, (2) maintaining and improving the integrity of the cadastre data over time, and (3) integrating these data with related data layers. Although the workflow was developed for Rapid City, it is scalable and it can be applied by any organization that maintains land records

Pedal Power: Explorers and commuters of New York Citi Bikesharing scheme.

Bike share schemes are increasing in popularity. During 2013, New York City (NYC) launched a bike sharing scheme, Citi Bike, to provide users with the ability to cycle around the city. How these bikes are used is useful for understanding sustainability and infrastructure needs in urban cities. In this study spatial analysis methods were used to analyze space and time usage patterns during a 12 month period. We found that bike usage varied over the months with the lowest number of rentals occurring during the winter months (N = 200,000) and highest during the summer months (N > 1 million trips). Bike use varied spatially and temporally by user type (customer vs subscriber) and gender (male vs female). Over 100,000 unique routes (origin-destinations) were identified with the top five most popular routes starting and ending at the same station location. When comparison of existing bike distributions were made with bike use patterns, supply gaps were identified. The findings are useful for enhancing infrastructure needs and provide a basis for future comparisons to be made as the system changes over time

The Sociospatial Network: Risk and the Role of Place in the Transmission of Infectious Diseases.

Control of sexually transmitted infections and blood-borne pathogens is challenging due to their presence in groups exhibiting complex social interactions. In particular, sharing injection drug use equipment and selling sex (prostitution) puts people at high risk. Previous work examining the involvement of risk behaviours in social networks has suggested that social and geographic distance of persons within a group contributes to these pathogens' endemicity. In this study, we examine the role of place in the connectedness of street people, selected by respondent driven sampling, in the transmission of blood-borne and sexually transmitted pathogens. A sample of 600 injection drug users, men who have sex with men, street youth and homeless people were recruited in Winnipeg, Canada from January to December, 2009. The residences of participants and those of their social connections were linked to each other and to locations where they engaged in risk activity. Survey responses identified 101 unique sites where respondents participated in injection drug use or sex transactions. Risk sites and respondents' residences were geocoded, with residence representing the individuals. The sociospatial network and estimations of geographic areas most likely to be frequented were mapped with network graphs and spatially using a Geographic Information System (GIS). The network with the most nodes connected 7.7% of respondents; consideration of the sociospatial network increased this to 49.7%. The mean distance between any two locations in the network was within 3.5 kilometres. Kernel density estimation revealed key activity spaces where the five largest networks overlapped. Here, the combination of spatial and social entities in network analysis defines the overlap of vulnerable populations in risk space, over and above the person to person links. Implications of this work are far reaching, not just for understanding transmission dynamics of sexually transmitted infections by identifying activity "hotspots" and their intersection with each social network, but also for the spread of other diseases (e.g. tuberculosis) and targeting prevention services

It’s a long, long walk: accessibility to hospitals, maternity and integrated health centers in Niger

BACKGROUND: Ease of access to health care is of great importance in any country but particularly in countries such as Niger where restricted access can put people at risk of mortality from diseases such as measles, meningitis, polio, pneumonia and malaria. This paper analyzes the physical access of populations to health facilities within Niger with an emphasis on the effect of seasonal conditions and the implications of these conditions in terms of availability of adequate health services, provision of drugs and vaccinations. The majority of the transport within Niger is pedestrian, thus the paper emphasizes access by those walking to facilities for care. Further analysis compared the change in accessibility for vehicular travel since public health workers do travel by vehicle when carrying out vaccination campaigns and related proactive health care activities. RESULTS: The majority of the roads in Niger are non-paved (90%). Six districts, mainly in the region of Tahoua lack medical facilities. Patient to health facility ratios were best in Agadez with 7000 people served per health facility. During the dry season 39% of the population was within 1-hours walk to a health center, with the percentage decreasing to 24% during the wet season. Further analyses revealed that vaccination rates were strongly correlated with distance. Children living in clusters within 1-hour of a health center had 1.88 times higher odds of complete vaccination by age 1-year compared to children living in clusters further from a health center (p < 0.05). Three key geographic areas were highlighted where access to health centers took greater than 4 h walk during the wet and dry season. Access for more than 730,000 people can be improved in these areas with the addition of 17 health facilities to the current total of 504 during the dry season (260,000 during the wet season). CONCLUSIONS: This study highlights critical areas in Niger where health services/facilities are lacking. A second finding is that population served by health facilities will be severely overestimated if assessments are solely conducted during the dry season. Mapped outputs can be used for future decision making processes and analysis
