This paper develops a statistical framework to analyze the effectiveness of vegetation management at reducing power outages during storms of varying severity levels. The framework was applied on the Eversource Energy distribution grid in Connecticut, USA based on 173 rain and wind events from 2005–2020, including Hurricane Irene, Hurricane Sandy, and Tropical Storm Isaias. The data were binned by storm severity (high/low) and vegetation management levels, where a maximum applicable length of vegetation management for each circuit was determined, and the data were divided into four bins based on the actual length of vegetation management performed divided by the maximum applicable value (0–25%, 25–50%, 50–75%, and 75–100%). Then, weather and overhead line length normalized outage statistics were taken for each group. The statistics were used to determine the effectiveness of vegetation management and its dependence on storm severity. The results demonstrate a higher reduction in damages for lower-severity storms, with a reduction in normalized outages between 45.8% and 63.8%. For high-severity events, there is a large increase in effectiveness between the highest level of vegetation management and the two lower levels, with 75–100% vegetation management leading to a 37.3% reduction in trouble spots. Yet, when evaluating system reliability, it is important to look at all storms combined, and the results of this study provide useful information on total annual trouble spots and allow for analysis of how various vegetation management scenarios would impact trouble spots in the electric grid. This framework can also be used to better understand how more rigorous vegetation management standards (applying ETT) help reduce outages at an individual event level. In future work, a similar framework may be used to evaluate other resilience improvements.

This chapter illustrates a few things people need to know to live well in rural Canada, especially those who are aging. It emphasizes the need for a reliable vehicle and knowledge on what to do and prepare for emergencies, such as power outages, snowstorms, ice buildup, and vehicle and machine breakdowns. It also points out how the small size of rural communities can lead to social isolation, especially for someone who is new to the area. the chapter reviews observations and knowledge of aging experiences, challenges, and opportunities in two communities in rural New Brunswick. It starts with an overview of each community in New Brunswick, followed by a summary of the unique barriers and opportunities to aging well in rural areas.

<p>Twenty rivers have been estimated previously to account for almost 70% of global plastic emissions to the marine environment. Of these, the Ganges River was second only to the Yangtze River. Yet, scale and complexity of the Ganges River network make assessing microplastic contamination along the watercourse, including the attribution of suspected pollution sources challenging. Here we analyse post-monsoon spatial variation of microplastics along a 2500km length of the Ganges. River sediments and surface water were sampled during Nov/Dec 2019 at 81 locations that covered a variety of hydrological conditions, morphological attributes and land-use categories (e.g., downstream of large urban areas, rural areas with agriculture, major tributaries). Sediment samples were collected from the riverbank (waterline) and stored in glass jars while 100L water samples were filtered on-site through a 63µm sieve. Plastic particles between 63 and 5000µm were extracted by means of density separation followed by organic matter digestion with Fenton reagent. Extracts were subsequently stained with Nile red to improve detection of ambiguous particles. Physical and chemical properties such as shape, size, and polymer type where characterised using Fluorescence microscopy, Confocal Raman, and FT-IR imaging to understand differences along the river continuum. Our findings were analysed in relation to other key water quality parameters, various land-use descriptors and hydrogeomorphological characteristics, which allowed us to better understand the main drivers of microplastic transport and fate. Our survey results reveal an increasing downstream trend in sediment microplastic concentrations. The existence of distinct microplastic pollution hotspots in areas of high population density as well as areas of high cultural and spiritual relevance are detected. Interestingly, longitudinal concentration profiles in sediment and surface water samples do not match, hinting at differences in source attributions as well as transport, accumulation and long-term storage mechanisms, which is especially important in light of the variations seen in microplastic shape and size distribution patterns. Our results can be used as a springboard for future research assessing local microplastic contamination and aid in the refinement of medium and large-scale models estimating microplastic export.</p>

Abstract Ice storms have a variety of negative effects on society. Through an analysis of newspaper accounts of nine exceptional ice storms, the most widespread and longest lasting impact is the loss of electrical power. Power outages also cause secondary effects, such as carbon monoxide poisoning and fire, and they can force people to leave their homes because of a lack of heat. Other impacts of ice storms are transportation disruptions, school and business closings, and economic losses to agriculture and some business sectors. However, some businesses, such as those associated with the hospitality sector, actually benefit from ice storms. Modern power outages have a longer duration than those associated with earlier storms. Rural areas are most likely to suffer from long power outages because utilities prioritize areas with greater numbers of customers and because fallen trees may limit accessibility. Several suggestions for reducing electrical disruption, such as aggressive tree-trimming programs and burial of lines, are analyzed. While these may help, less reliance on electricity for lighting and heating systems could also provide a benefit.

This report deals with an effort to begin the process of effectively identifying children in rural areas with speech and language problems using existing school personnel. A two-day competency-based workshop for the purpose of training aides to conduct a large-scale screening of speech and language problems in elementary-school-age children is described. Training strategies, implementation, and evaluation procedures are discussed.

Telepractice technology allows greater access to speech-language pathology services around the world. These technologies extend beyond evaluation and treatment and are shown to be used effectively in clinical supervision including graduate students and clinical fellows. In fact, a clinical fellow from the United States completed the entire supervised clinical fellowship (CF) year internationally at a rural East African hospital, meeting all requirements for state and national certification by employing telesupervision technology. Thus, telesupervision has the potential to be successfully implemented to address a range of needs including supervisory shortages, health disparities worldwide, and access to services in rural areas where speech-language pathology services are not readily available. The telesupervision experience, potential advantages, implications, and possible limitations are discussed. A brief guide for clinical fellows pursuing telesupervision is also provided.
