After the fall of the soviet union: the changing status of local governments in the republic of latvia

1999

When the Republic of Latvia gained its independence from the Soviet Union in 1991, one of Latvia's first priorities was to rebuild its system of local government. This article describes many of the problems local governments in Latvia faced after 50 years of communist rule. The article also discusses the new Latvian laws which changed the structure of local government in that country. Also discussed are Latvian central government institutions which impacted on local governments in general and local government finances in particular. The unique status of the Capitol City of Riga, Latvia's largest municipality is also reviewed in detail.

Short-duration rainfalls in Sicily

1990

The Italian Hydrographic Service publishes yearly maximum rainfall depths with 1-, 3-, 6-, 12-, and 24-hr duration, recorded by recording rain gauges. It also publishes selected short-duration (t<1 hr) rainfall amounts. It is impossible to carry out a statistical analysis of the short-duration rainfalls for each recording rain gauge because the published data correspond to different record durations and to different recording rain gauges from year to year. Therefore, there is a practical need to derive empirical relationships between the 1-, 3-, 6-, 12-, and 24-hr duration amounts and shorter duration (t<1 hr) rainfall amounts. Such a relationship has been proposed by Bell and has been veri…

Honouring the opening: Unfolding the rich ground between the philosophical thinking of Martin Heidegger and practice-based empirical work

2021

The aim of this article is to bring philosophical thinking closer to practice-based empirical work. Using Martin Heidegger’s philosophy, it offers a bridge between these two worlds, attempting to provide philosophical depth to the findings of a hermeneutic phenomenological study. This process unfolded through the appearance of three intertwined, potential, meaningful modes of being in the lifeworld: space as a condition for being and being for worlding the world; temporal and spatial self-being, the existence of multiple selves in time and space; and suffering and thriving as modes of being. The article extends the dialogue and concludes with key reflections and insight for research practic…

Uso de medicamentos associados ao risco de quedas em idosos não institucionalizados

2018

RESUMEN Objetivo: Determinar qué número de medicamentos consumidos diariamente es influyente en el riesgo de caídas en ancianos no institucionalizados y con historial de caídas en el último año. Método: Estudio descriptivo mediante muestreo aleatorio con la utilización de los siguientes instrumentos de medida: cuestionario de la OMS para el estudio de caídas en el anciano, escala de marcha y escala depresión geriátrica y escala de marcha y equilibrio. El análisis univariante, bivariante con prueba no paramétrica de Chi-cuadrado y regresión logística binaria se ellevó a cabo con el programa estadístico SPSS versión 21.0. Resultados: Participaron del estudio 213 personas. El consumo ≥ a 4 med…

This paper presents a mathematical model for robust production planning. The model helps fashion apparel suppliers in making decisions concerning allocation of production orders to different production plants characterized by different lead times and production costs, and in proper time scheduling and sequencing of these production orders. The model aims at optimizing these decisions concerning objectives of minimal production costs and minimal tardiness. It considers several factors such as the stochastic nature of customer demand, differences in production and transport costs and transport times between production plants in different regions. Finally, the model is applied to a case study.…

How to formulate an accident prediction model for urban intersections.

2009

Several safety prediction models and methods have been developed to eliminate the relationship between the expected accident frequency and various urban intersection geometry and operational attributes. It is generally accepted that accident rates tend to be higher at intersections than on through sections of a road. This is particularly frequent in urban area where roads are characterized by intersections in close succession; moreover, the safe and effective operations of the urban road system can be significantly affected by safety conditions at intersections. In this paper models and methods designed to understand and to predict the accident process at urban intersections are reviewed. I…

Effects of soil management techniques on soil water erosion in apricot orchards.

2016

Soil erosion is extreme in Mediterranean orchards due to management impact, high rainfall intensities, steep slopes and erodible parent material. Vall d'Albaida is a traditional fruit production area which, due to the Mediterranean climate and marly soils, produces sweet fruits. However, these highly productive soils are left bare under the prevailing land management and marly soils are vulnerable to soil water erosion when left bare. In this paper we study the impact of different agricultural land management strategies on soil properties (bulk density, soil organic matter, soil moisture), soil water erosion and runoff, by means of simulated rainfall experiments and soil analyses. Three rep…

The influence of rainfall time resolution for urban water quality modelling

2010

The objective of this paper is the definition of a methodology to evaluate the impact of the temporal resolution of rainfall measurements in urban drainage modelling applications. More specifically the effect of the temporal resolution on urban water quality modelling is detected analysing the uncertainty of the response of rainfall–runoff modelling. Analyses have been carried out using historical rainfall–discharge data collected for the Fossolo catchment (Bologna, Italy). According to the methodology, the historical rainfall data are taken as a reference, and resampled data have been obtained through a rescaling procedure with variable temporal windows. The shape comparison between ‘true’…

Runoff initiation, soil detachment and connectivity are enhanced as a consequence of vineyards plantations.

2017

[EN] Rainfall-induced soil erosion is a major threat, especially in agricultural soils. In the Mediterranean belt, vineyards are affected by high soil loss rates, leading to land degradation. Plantation of new vines is carried out after deep ploughing, use of heavy machinery, wheel traffic, and trampling. Those works result in soil physical properties changes and contribute to enhanced runoff rates and increased soil erosion rates. The objective of this paper is to assess the impact of the plantation of vineyards on soil hydrological and erosional response under low frequency - high magnitude rainfall events, the ones that under the Mediterranean climatic conditions trigger extreme soil ero…

An automatic tool for reconstructing monthly time-series of hydro-climatic variables at ungauged basins

2017

Abstract Integrative information models for filling/reconstructing hydro-climatic time-series are required for a variety of practical applications. A GIS-based model for a rapid and reliable assessment of monthly time-series of several key hydro-climatic variables at the basin scale, is here developed as plug-in and applied to the entire region of Sicily (Italy). The plug-in, once the desired basin outlet section and time-window are selected, uses appropriate spatial techniques and algorithms to identify its drainage area and estimate the corresponding mean areal rainfall and temperatures time-series. A recent regional regressive rainfall-runoff model is successively applied for the assessm…
