This will be particularly disastrous if the grid is unprepared for the climate-induced shifts in electricity demand that will result from increased temperatures. Recently, the use of data-driven modeling has emerged as a way to predict these climate-induced changes in electricity demand, however, much of the work has focused on entire sectors or regions. Here, we focus on the impact of climatic variables on hourly household electricity use for air conditioning. Our goal was to determine the best model for predicting the air conditioning use based on climate variables, as well as use that model to extract insights related to the household-level climate-electricity nexus. Using smart meter data from three US cities (Austin, Texas, Ithaca, New York, and San Diego, California), we tested seven different models of varying complexity. Ultimately, Bayesian additive regression trees (BART) was selected as the best model across all three cities (NRMSE ranged between 0.085 and 0.250). Additionally, we found that while the majority of the climate variables were important, relative humidity was the most important variable in each city. Given that air conditioning tends to drive non-base electricity demand in the summer, understanding these nuances in the climate-electricity nexus as it applies to air conditioning is critical for building a resilient grid.</p></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"89 ","pages":"Article 101664"},"PeriodicalIF":6.1,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44943795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study develops an efficient and comprehensive gauging system, which combines criteria importance through the intercriteria correlation (CRITIC), preference ranking organization method for enrichment evaluation (PROMETHEE II), and principal component analysis (PCA), namely CRITIC–PROMETHEE II–PCA, to provide the G20 countries with a tool for quantifying transport safety success. Comparisons of the results with those derived from other classical approaches confirm the robustness and feasibility of the proposed methodology across different socioeconomic and demographic backgrounds. This will allow policymakers to formulate corresponding reform measures and allocate investments rationally. This tool will notably enable the G20 to monitor road safety progress, set short- and long-term reform goals, introduce relevant regulations, and distribute investment and resources in a quick and timely manner.

Incorporating real conditions and the perspective of decision-makers in the analysis is crucial to enhance the practical value and managerial implications. Although it is known that implementation can be hindered by the lack of practitioner input in the structure of the model, its priorities, and the practicality of solution times, the way these aspects have been introduced in humanitarian optimization models has not been investigated. This study looks at the way research has involved practitioners in different aspects of the design of optimization models to promote implementation. It investigates the aspects affecting the implementation of the models and opportunities to guide future optimization contributions. The article introduces a systematic literature review of 105 articles to answer the research questions. The results are contrasted with a multi-criteria decision analysis using responses from Mexican practitioners. The study found that only 10% of the articles involved practitioners for modelling decisions, which was confirmed by a major gap between the objectives used in the literature and the priorities of Mexican practitioners. In terms of swift decision-making, fewer than 22% of the articles surveyed introduced new solution methods to deliver results in a sensible time. The study also identified very limited inclusion of environmental concerns in the objective functions even though these are a priority in the global agenda. These findings are discussed to propose research directions and suggest best practices for future contributions to promote the implementation of humanitarian logistics models.</p></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"89 ","pages":"Article 101669"},"PeriodicalIF":6.1,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46927830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We provide evidence that the presence of organised crime at local level significantly decreases the scores achieved by primary school students, undertaking the INVALSI test for literacy in Southern Italy.
