Abstract:
Drought is a repetitive phenomenon in different continents and its effects are not limited only to dry and semidry areas, but they could also be seen in areas with high rates of precipitation and in any season of the year. One of the most important stages in monitoring the drought is to determine indices in order to analyze its intensity, continuity and frequency. The data related to the overall monthly precipitation collected from synoptic stations of the area during the statistical period of 1976-2005 have been used for monitoring drought in Guilan and analyzing its characteristics.

Abstract:
AbstractIn order to examine equivalent axles load with dynamic load taken into account, pavement roughness test is carried out with a Vehicle Axle-tire Dynamic Load Tester, where axle-tire vertical acceleration of heavy trucks and light trucks are tested, respectively. Dynamic load is considered as a series of static loads following a normal distribution, and equivalent axles load is calculated according the Asphalt Pavement Design Specification. The results show that equivalent axles load time increase accordingly based on highway class. when tensile strain at bottom of surface is taken as design index, on high class highway equivalent standard load increases 8.3–14.9% for heavy truck, 3.6–5.4% for light truck; on low class highway, it increases 6.8–17.3% for heavy truck, 3.2–12.5% for light truck; when tensile stress at the bottom of semi-rigid base is taken as checking index. On a high class highway, it increases 34.2–64.9% for a heavy truck, 14.2–21.8% for a light truck; on a low class highway, it increases 27.5–77.1% for a heavy truck, 12.6–53.2% for a light truck. These research findings provide in-depth understanding regarding vehicle axle load conversion in dynamic load environment.

Abstract:
AbstractUrban greenspaces can affect the physical and mental health of city residents and they can also contribute to improving urban environmental quality in ways that can benefit human health. Dhaka, a megacity with over 22.4 million residents, has progressively lost its greenspace over the past decade as the city has grown and urbanised. This study evaluates the availability and accessibility of greenspace considering its population and residential areas, as well as assessing the changes to greenspace in the last 30 years throughout the city. We utilized secondary data from the 2011 Census and areal imagery to perform the analysis for city wards, the smallest administrative unit, using ArcGIS software. We generated geospatial maps of greenspace distribution and accessibility as well as vegetation, land surface temperature and humidity in different years. Accessibility to greenspace was measured with 100-meter and 300-meter buffer zones, and a total of 56.5 square kilometers area of 77.47 square kilometers of residential area fell under these territories. Changes in vegetation were obtained using Normalized Difference Vegetation Index (NDVI) for the years 1990, 2000, 2010, and 2020, and a high level of loss in vegetation was observed. Land Surface Temperature (LST) and Normalized Difference Moisture Index (NDMI) were used to assess the temperature and humidity for the same years. We measured that Dhaka has 2.24% greenspace coverage and only 2 wards out of 110 have greater than 20% greenspace coverage. A highest estimate of 0.003207 square meter per capita greenspace was found at ward-46, which does not even meet the minimum health standard. Increased temperature and decreased humidity were observed in Dhaka city from 1990 to 2020, in a level that may adversely impact on the city population’s public health. We found a high correlation between NDVI with LST and NDMI. In 49% of wards, vegetation and humidity decreased, whereas temperature increased. This study provides noteworthy information on the lack of greenspace throughout Dhaka city. The spatial distribution of greenspace provided in the study has the potential to be useful in taking measures for improving sustainable greenery management in the city area and the health of Dhaka’s growing population.

Abstract:
AbstractWe wrote this book with the central goal of documenting patterns and trends of racial and ethnic segregation across communities and over time in the United States using refined methods of measurement analysis, which can sometimes be expected to change what we thought we knew from past research and at other times add more to our understanding of established patterns. In making this our goal, we produced several contributions that happily build continuity with past research and set a foundation for future research, which we can expect to come in waves each time there is a decennial census data release. First and foremost, by using measures of segregation that are free of index bias and specifically employing the separation index, a measure of evenness that can dependably signal when prototypical patterns of segregation are occurring, we were able to reanalyze and describe patterns and levels of racial and ethnic residential segregation across the United States and over time. We are not the first to describe patterns of segregation, here operationalized as the uneven distribution of two groups across neighborhood-level spatial units, across communities and over time in the United States. But we are the first to simultaneously use measures that are corrected for index bias, measure segregation of households rather than persons, and expand our analysis to not only metropolitan areas but also micropolitan areas and noncore counties. Our findings should be viewed as reliable benchmarks for descriptive analyses of racial and ethnic residential segregation across a broad range of communities moving forward and should also be taken instructively, as they demonstrate the application of the methodological changes that we recommend should be the standard for residential segregation measurement. We also use Fossett’s (2017) difference-of-means calculation of segregation indices to demonstrate new approaches for linking locational attainments to residential segregation patterns, situating segregation quantitatively as a stratification outcome. In this final chapter, we describe how this study establishes continuity with past research and sets the path for residential segregation research in the future.

Abstract:
In order to better understand Extreme Fire Event conditions at the regional level in Portugal, a preliminary analysis on drought conditions and forest fires considering NUT III administrative organization was performed and is presented in this work. This analysis will support a more comprehensive study on the relation between weather-climate conditions (drought, heat, wind) and forest fires (occurrences and burned areas). To classify the drought, two drought indices were considered – PDSI (Palmer Drought Severity Index) and SPI (Standardized Precipitation Index), the last one for 3- and 6 months time scales. The computation was based on weather station observations for the period 1981 - 2019 in mainland Portugal, with aggregation in 23 NUT III on a monthly basis. To analyse the forest fires distribution per NUT III a monthly dataset of fire occurrences and burned areas during the period was used. The exploratory analysis was carried out in the STATISTICA software, using two clustering methods (K-Means and tree clustering). Since the results of those methods are subjective, before applying them, in the case of drought, the ideal number of clusters was calculated, making a sensibility analysis using the R tool NbClust. The results from clustering are presented through maps in which the groups of NUT III regions with the same behaviour are identified.

<em>Abstract</em>.—Studies demonstrating the mechanisms regulating biodiversity are uncommon. Streams and rivers worldwide display a longitudinal gradient in fish biodiversity, and most prior research has used correlative evidence to infer that higher downstream diversity is produced by factors facilitating greater niche separation. We combine 20 years of fish abundance samples from a representative southern Appalachian stream with critical swimming velocity experiments to provide direct evidence that a shifting hydrodynamic barrier affects this gradient in Coweeta Creek. We observed increased diversity in multiple sites, produced by species immigrating upstream during periodic droughts (1985–1988, 1999–2002) and a highly significant positive relationship (<em>r<sup></em>2</sup> = 0.77) between drought (Palmer index) and Shannon-Weiner diversity. Resident fish generally had smaller standard lengths during drought periods. Critical velocity measurements showed that residents could tolerate faster water velocities than drought immigrants and that upstream velocities in nondrought years were faster than those in some downstream sites. These data support the hypothesis that local fish diversity in this system is limited by the ability of drought immigrants to pass an upstream hydrodynamic barrier. Alternative hypotheses such as temperature differences between sites, increased capture efficiency during droughts, and increased productivity during droughts were not supported by the data. The relationship between drought and diversity in this system is counterintuitive because drought should reduce resource availability and produce lower rather than higher diversity. These results highlight the important relationship between natural flow variation and maintenance of local diversity and demonstrate the need for long-term ecological data.

Abstract:
Abstract When the variance of a population of random variables is non stationary, the population kurtosis is greater than the kurtosis of the probability distribution of the individual random variables. Therefore, the high kurtosis observed in the distribution of security prices can be explained by high kurtosis in the individual price changes, non stationarity in the variances of the price changes, or any combination of these two causes. For a 100-year series of monthly changes in the Standard & Poor’s Composite Index, fluctuations in variance as forecasted by a two-parameter model explain 70 percent of the deviation of the sample kurtosis from normality. The results suggest that increments in the logarithms of security prices obey a normal distribution with predictably fluctuating variance.

This research aims to study a change of rainfall and indicate levels of agricultural drought in the Southwest monsoon period of the northern region of Thailand by using the GMI. The rainfall data from June to September of the year 1987 to 2019 were collected from 21 meteorological stations over the northern region of Thailand. The data were used to create the maps of agricultural drought levels and to analyze the distribution of agricultural drought on the study period. Then, the distribution of total rainfall maps of each month and the trend of rainfall over the past 33 years were examined. T

Abstract:
Drought is a complex and challenging weather-related disaster with significant economic, social, and environmental impacts. Traditional drought monitoring, which primarily relies on ground observations, often falls short due to limited spatial coverage and data scarcity. Most existing drought indices focus on a single variable, which may not adequately capture the full scope of drought conditions. To address this, integrating multiple parameters from remote sensing data presents a promising approach, providing spatially distributed and real-time information for a more accurate and comprehensiv

Abstract:
In the United States, investors leave large amounts of money on the table when investing in index funds. I show that even though high fees strongly predict poor performance, investors have little sensitivity to fees. This can be explained by fund intermediation in the retail sector and the legal standard of care that intermediaries have towards their clients. Net inflows to high-fee funds are higher when brokers and financial advisors receive sales commissions from the investment management company. When funds are sold through intermediaries held to higher standard of care, such as those sold

Abstract:
As cities densify to meet environmental and economic goals, the equitable distribution of urban green spaces (UGS) becomes critical for fostering community well-being, promoting environmental justice, and enhancing climate resilience. This report presents a synthesis study conducted by the Swedish University of Agricultural Sciences (SLU) in collaboration with Nilsson Landscape, aimed at understanding the relationship between socio-economy and accessibility to UGS, to assess and enhance green equity in urban environments. The research focuses on Malmö specifically, and have involved Region Skå

Abstract:
Achieving the Sustainable Development Goals (SDGs) of poverty and inequality reduction through redistribution have indeed become critical concerns in many low- and middle-income countries, including Nigeria. Although redistribution results from the effect of tax revenue collections, micro household-level empirical analyses of the distributional effect of personal income tax (PIT) and value added tax (VAT) reforms in Nigeria have been scarcely carried out. This study for the first time quantitatively assessed both the equity and redistributive effects of PIT and VAT across different reform scen

Abstract:
With the proliferation of Free Trade Agreements (FTAs) over the past decade, demand for quantitative analysis of their likely impacts has surged. The main quantitative tool for performing such analysis is Computable General Equilibrium (CGE) modeling. Yet these models have been widely criticized for performing poorly (Kehoe, 2002) and having weak econometric foundations (McKitrick, 1998; Jorgenson, 1984). FTA results have been shown to be particularly sensitive to the trade elasticities, with small trade elasticities generating large terms of trade effects and relatively modest efficiency gain

Abstract:
Objectives. Diagnostic errors are a known patient safety concern across all clinical settings, including the emergency department (ED). We conducted a systematic review to determine the most frequent diseases and clinical presentations associated with diagnostic errors (and resulting harms) in the ED, measure error and harm frequency, as well as assess causal factors. Methods. We searched PubMed®, Cumulative Index to Nursing and Allied Health Literature (CINAHL®), and Embase® from January 2000 through September 2021. We included research studies and targeted grey literature reporting diagnosti
