Palic and Ludas lakes are located in the northern part of Vojvodina, Serbia near the town of Subotica, just a few kilometers south of the Hungarian border. While Palic lake has a long history as a tourist attraction and a nice recreational setting, Ludas lake and the surrounding steppe plains are habitats of international importance and protected by the Ramsar convention on wetlands. The lakes are connected through the Palic-Ludas canal. Thus Ludas lake is fed partially from Palic lake, but also supplied by the Körös river. The majority of the catchment area of the Körös river is in Hungary, this way the water supply problems related to the lakes are transboundary. The lake system is also drained by the Körös, which finally enters the Tisza river. Water quality problems and water quantity decrease are both identified and are escalating threatening factors at the lake system in the past decades. Several studies have been carried out in the past about the possible reasons and solutions. The authors have studied the previously published results and have been participating in a cross-border cooperation project funded by the IPA, in frame of which a comprehensive survey and measurement program has been carried out in order to develop, among others, a rainfall-runoff model of the catchment for the investigation of water supply scenarios of the lake system in order to substantiate a monitoring network and program for the sustainable management of the lakes. In our article we introduce the area, the problem, the field surveying and measurement methodologies and results, the modeling process and the model itself, concluding transboundary responsibility for water supply to the lake system, with a possible complex connection to one of Hungary’s major water management issues.

Residual Malaria Transmission

Despite dramatic reductions in malaria cases in the catchment area of Macha Hospital, Choma District, Southern Province in Zambia, prevalence has remained near 1–2% by RDT for the past several years. To investigate residual malaria transmission in the area, this study focuses on the relative abundance, foraging behavior, and phylogenetic relationships of Anopheles squamosus specimens. In 2011, higher than expected rates of anthropophily were observed among “zoophilic” An. squamosus, a species that had sporadically been found to contain Plasmodium falciparum sporozoites. The importance of An. squamosus in the region was reaffirmed in 2016 when P. falciparum sporozoites were detected in numerous An. squamosus specimens. This study analyzed Centers for Disease Control (CDC) light trap collections of adult mosquitoes from two collection schemes: one performed as part of a reactive-test-and-treat program and the second performed along a geographical transect. Morphological identification, molecular verification of anopheline species, and blood meal source were determined on individual samples. Data from these collections supported earlier studies demonstrating An. squamosus to be primarily exophagic and zoophilic, allowing them to evade current control measures. The phylogenetic relationships generated from the specimens in this study illustrate the existence of well supported clade structure among An. squamosus specimens, which further emphasizes the importance of molecular identification of vectors. The primarily exophagic behavior of An. squamosus in these collections also highlights that indoor vector control strategies will not be sufficient for elimination of malaria in southern Zambia.

AbstractOver the past decade, electric vehicles (EVs) have been considered in a growing number of models and methods for vehicle routing problems (VRPs). This study presents a comprehensive survey of EV routing problems and their many variants. We only consider the problems in which each vehicle may visit multiple vertices and be recharged during the trip. The related literature can be roughly divided into nine classes: Electric traveling salesman problem, green VRP, electric VRP, mixed electric VRP, electric location routing problem, hybrid electric VRP, electric dial-a-ride problem, electric two-echelon VRP, and electric pickup and delivery problem. For each of these nine classes, we focus on reviewing the settings of problem variants and the algorithms used to obtain their solutions.

Purpose – The aim of this paper is to present a comprehensive survey of workplace productivity key performance indicators used in the office context. Academic literature from the past ten years is systematically reviewed and contextualized through a series of expert interviews. Design/methodology/approach – The authors present a systematic review of literature to identify Key Performance Indicators (KPIs) and methods of workplace productivity measurement, complemented by insights semi-structured interviews to inform a framework for a benchmarking tool. 513 papers published since 2007 were considered, of which 98 full-length papers were reviewed, and 20 were found to provide significant insight and are summarized herein. Findings – Currently, no consensus exists on a single KPI suitable for measuring workplace productivity in an office environment, though qualitative questionnaires are more widely adopted than quantitative tools. The diversity of KPIs used in published studies indicates that a multidimensional approach would be most appropriate for knowledge-worker productivity measurement. Expert interviews further highlighted a shift from infrequent, detailed evaluation to frequent, simplified reporting across human resource functions and this context is important for future tool development. Originality/value – This paper provides a summary of significant work on workplace productivity measurement and KPI development over the past ten years. This follows up on the comprehensive review by B. Haynes (2007a), providing an updated perspective on research in this field with additional insights from expert interviews.

Effects of age on the distribution of specific life events experienced during the past year by community-based adults were examined controlling for sex, race, education, marital status, and place of residence. The controlled analyses were done using logistic regression. Data were gathered via personal interview from 3,798 respondents ages eighteen years and over who participated in the Epidemiologic Catchment Area (ECA), community survey from North Carolina. Respondents were placed in one of four age groups. The percentage of respondents reporting each of the nineteen events examined ranged from 0.5 percent for death of spouse to 19.1 percent for death of loved one. Age was an important predictor in the controlled analysis for thirteen of the seventeen life events examined. A majority of differences occurred between the youngest and oldest age groups. Age differences were not found for illness of one week or more involving activity limitation.

Prior to Manila Water's entry into the East Zone as MWSS's concessionaire in 1997, the water supply and distribution system was characterized by low service coverage, high levels of leakage due to pilferage and deteriorating pipes, limited water availability and poor operating efficiencies. This presentation details how the MWSS PPP framework, coupled with Manila Water's multi-pronged, corporate approach, has been key to reversing the sorry state which Metro Manila's East Zone found itself in before 1997. Crucial to the success of Manila Water was the adoption of a multi-pronged corporate strategy composed of five interrelated variables: (1) Profit Model, (2) Market/Customer, (3) Resources, (4) Systems and Processes and (5) Talent and Organization. The presentation explains how these factors have come together to bring out the “virtuous cycle” in the East Zone. The numerous achievements of Manila Water over the past thirteen years, which are highlighted in the last section of the presentation, have been directly attributed to the successful corporate strategy employed by Manila Water.

Abstract Adverse effects of future climate change on water supply systems are of concern. High turbidity caused by abrupt flood, and drought caused by continuous dry days are the major risks. To assess such risks, a comprehensive method to simulate hydrology with high spatiotemporal resolution should be developed. In this study, a series of methods from parameter estimation to future simulation using the Soil and Water Assessment Tool (SWAT) was demonstrated for Sagami Dam reservoir, which is a typical water supply reservoir in Japan. A proposed parameter calibration method by optimizing percent bias followed by optimizing Nash–Sutcliffe efficiency gave good performance of model prediction of the daily average reservoir inflow in the past. Using this model, the changes in inflow under expected climate change were simulated. Three predicted daily climates by the Model for Interdisciplinary Research on Climate version 5 (MIROC5) under three representative concentration pathways, i.e., RCP 2.6, 4.5, and 8.5, in 2081–2100 were used for the simulation, whereas observed daily climate during 1981–2000 was used as the past reference. The risks were discussed by considering their seasonality, indicating increases in flood and drought in June and July, and in February and April, respectively.

Insufficient Knowledge

The relevance of the presented research is determined by insufficient knowledge from the historical and legal standpoint of conducting operational and preventive measures, such as a week (decade, month) of road safety, but at the same time their high significance and effectiveness. In this paper, on the basis of previously unknown archival documents and materials, organizational and legal measures are considered for the first in domestic practice decade of road safety in the territory of Donbass. The attention is focused on the key areas of preparation and implementation of the Decade plan by local authorities and public organizations. The nature of the preparation and implementation of the planned road safety decade plan does not lose its relevance at the present stage. Today, the road safety week has gained international importance and is being implemented with the support of the United Nations. At the regional level, as in the past, a week (decade, month) of road safety is actively being held, while the nature of the activities and their intended purpose, for the most part, have remained unchanged, but at the same time, the urgent problem is the lack of a unified procedure for carrying out these events.

The potential threat of a landfill projected on a high karst plateau in southwest Montenegro is investigated with respect to the subjacent nearby springs. The locality is called Duboki do. As the springs are used for drinking water supply this investigation is urgently needed. For the springs exist two hypotheses concerning their catchment area: I) from the high karst plateau, or II) from a topographically lower area. The stable H- and O-isotope ratios of water samples from the springs are compared with precipitation isotope data, to reveal the catchment area of the springs. The isotope results indicate that the catchment area of the springs is at higher altitude fitting to, and in good agreement with, winter precipitation from the high karst plateau of the planned land-fill locality.
