No full textIdentification of suitable sites for managed aquifer recharge under semi-arid conditions employing a combination of numerical and analytical techniques
No full textAbstract
Overpumping or overexploitation of groundwater is one of the major threats for aquifer systems in arid and semi-arid areas. Managed aquifer recharge (MAR) has been suggested by many researchers as a sustainable and effective method to alleviate negative impacts of overpumping. Optimizing artificial recharge considers the selection of suitable MAR sites in terms of surface and subsurface characteristics. While surface characteristics at potential MAR sites could be modified (e.g. slope, soil texture, etc.), subsurface characteristics cannot be changed through engineering work. Characteristics of the aquifer, such as depth to groundwater, play an important role in determining the capability of an aquifer to store a specific volume of infiltrated water. Currently, only a limited number of quoted researches are available that consider factors related to aquifer characteristics and the range of these factors to identify optimal MAR sites. In this study, a new approach is presented, that employs numerical groundwater modeling to generate MAR suitability maps considering sub-surface characteristics, such as depth-to-groundwater, aquifer transmissivity and specific yield. Multiple model-runs are conducted to simulate groundwater table response with respect to the volume of infiltrated water. Simulation results are used to calibrate a groundwater mound empirical equation that calculates the groundwater level increase as a function of the transmissivity and infiltrated water volume for a given value of aquifer’ specific yield, range of vertical hydraulic conductivities and a specific design and operation conditions of the MAR system. The empirical equation is employed in GIS to spatially calculate the height of groundwater mound beneath a hypothetical MAR site and to generate, based on that, suitability maps for MAR implementation. Assuming that MAR structures capture the median of monthly surface runoff rates at the respective wadi (catchment area), suitability maps are generated for different configurations/scenarios of aquifer hydraulic conductivity in a parameter study. The results highlight the importance of integrating aquifer characteristics (geometry and hydraulic parameters) and expected magnitudes and fluxes of infiltration water in delineating suitable sites for MAR.Georg-August-Universität Göttingen (1018

An Integrated Approach of Analyzing Management Solutions for the Water Crisis in Azraq basin, Jordan
Full text linkNatural groundwater replenishment in (semi-) arid areas is low and can be sometimes negligible as a result of low precipitation rates and high evapotranspiration. Therefore, groundwater resources in these areas can be considered as non-renewable. Due to increasing demand for water, aquifer systems have been subject to an over-abstraction depleting fossil water resources and causing numerous negative impacts; declining groundwater table and aquifer storage, salt water intrusion, land subsidence and other problems. Additionally, the disappearance of wetlands in many areas in the world has been associated with groundwater over-abstraction which constitutes a significant ecological lost. The Azraq oasis located in the heart of the desert in Jordan is an example of the degradation of an important ecosystem as a result of groundwater over-abstraction.
Azraq basin is characterized by high heterogeneity in groundwater recharge, where the main recharge area is in the north of the basin. The central part of the basin is covered by wetland known as the Azraq Oasis containing a wealthy biodiversity. Abstraction for agricultural and domestic purposes occur mainly around the oasis area, leading to drastic decline of groundwater table. In this study different management solutions for the basin including pumping strategies and application of Managed Aquifer Recharge are analyzed.
A groundwater model is first built and calibrated for the Azraq basin in order to understand the response of groundwater table at the oasis area to pumping practices as well as to remote groundwater recharge, and predict its behavior under possible future scenarios and management alternatives.
The application of Managed Aquifer Recharge (MAR) is then discussed with a focus on the analysis of subsurface characteristics which play the main role in determining the ability of an aquifer to accommodate a specific amount of infiltrated water. A new approach of employing numerical groundwater modeling in the generation of MAR suitability maps in terms of sub-surface characteristics is presented. A number of model-runs are conducted to simulate groundwater table’s response at different locations of the aquifer for different scenarios of infiltration water volumes. Simulation results are employed to calibrate an empirical equation that calculates the height of groundwater mound as a function of aquifer transmissivity and volume of infiltrated water, for a certain value of aquifer’ specific yield, a certain range of vertical hydraulic conductivity, and fixed design and operation conditions of MAR structure.

This empirical equation is applied in GIS to spatially calculate the height of groundwater mounding beneath a hypothetical MAR structure, and generate based on that suitability maps for MAR implementation. Suitability maps are generated for different scenarios of aquifer’s hydraulic conductivity and assuming MAR structures capture the 50th and 80th percentile of monthly amount of surface runoff at the respective wadi in the study area.
Three surface factors are investigated in the basin for their suitability for MAR implementation; slope, soil texture and soil thickness, to generate a MAR suitability map in terms of surface factors where a new decision system is proposed for the integration of factors.
Based on MAR suitability map three MAR structures were proposed in the basin. MAR scenarios along with a number of pumping scenarios were tested using the calibrated groundwater flow model. The calibrated model was also used to define the safe yield of the aquifer and predict the behavior of the aquifer under scenarios of climate change.
The results show that by the year 2045 groundwater decline will range between 15 and 25 meters if current pumping practices continue. The safe yield of the aquifer where the groundwater table stabilizes was found to be 70% less than current pumping rates, indicating that the aquifer is being exploited largely beyond its limits. Two scenarios of future groundwater recharge, where recharge rates were reduced 25% and 50%, were tested. Under these two scenarios, negligible impacts on the groundwater table in the oasis area were realized indicating that the aquifer can be considered as non-renewable.
The results show that the application of MAR in the basin doesn’t contribute greatly to increasing the safe yield. Under MAR scenario where the capacity of MAR dam is designed based on the 50th and 80th percentiles of monthly surface runoff, groundwater head will increase 0.7 and 1 m by the year 2045 respectively.
Finally, a multi-criteria analysis was conducted for choosing abstraction rate in the basin based on conflicting environmental and socio-economic criteria under two scenarios of the future development of economic and other demographic issues.
the safe yield scenario was found to be the alternative that contributes the most to the goal of choosing the abstraction rate in the basin for the scenario of future economic prosperity, while keeping the current pumping rate was found to be the best alternative under a scenario of poor economic and social awareness
Barriers and overcoming strategies to supply chain sustainability innovation
Full text linkThis study identifies a list of barriers that hinders adoption, implementation and upscaling of sustainable supply chain innovation in the manufacturing industry. It further proposes overcoming strategies that seek to aid management decision to dealing with these barriers systematically. A multi-criteria decision analysis method, the Best-Worst Method (BWM), is adopted to aid in the evaluation and prioritisation of the barriers and their overcoming strategies within the Indian manufacturing industry, an emerging economy. The results depict that, “lack of technical expertise and training”, “lack of R&D and innovation capabilities”, “popularity of traditional technology”, “high initial investment in latest technology” and “fear of extra workload and loss of flexibility” are the top five barriers that confronts the Indian manufacturing companies in their quest for adopting and implementing sustainable supply chain innovation practices. In addition, the overcoming strategic pathway for dealing with these barriers are provided. The findings provide managerial and policy insights for guiding the formation of strategic operations framework and resource allocation if these Indian manufacturing firms seeks to build sustainability into their supply chain innovations
CONTRASTING NARRATIVES OF RELIGIOUS CONVERSION: STUDY OF “KISAH MUALAF” VERTIZONE TV AND LOG IN HUSEIN JAFAR
Full text linkWith the increasing trend of religious mediatization, the topic of religious conversion has gained significant attention in the media, both as news content and as part of Islamic dakwah narratives in Indonesia. This narrative has been widely disseminated through new media and the internet, where religious conversion stories are frequently featured in Islamic dakwah videos that attract a large audience. This article examines the “Kisah Mualaf” segment on the Vertizone TV channel and the “Log In” program on Deddy Corbuzier’s channel. “Kisah Mualaf`” presents narratives of dramatic transformation of the converts, biblical validation, and the perceived mutual threat between Islam and Christianity, shaping a dakwah content formula that represents a new generation of convert preachers. On the other hand, “Log In”, hosted by Husein Jafar, frames religious conversion narratives through comedic gimmicks while emphasizing Indonesian pluralism, reflecting the perspectives of moderate Islamic groups. Through this study, the author explores the contrasting discourses on religious conversion as a prominent narrative within Indonesia’s digital dakwah sphere. Employing content analysis, netnography, and a review of existing literature, the author argues that two dominant religious conversion narratives have emerged among digital preachers, constituting not only a competition for audience engagement but also a contestation of discourse within Indonesia’s Islamic digital dakwah landscape.
Infodemiological data of high-school drop-out related web searches in Canada correlating with real-world statistical data in the period 2004–2012
Full text linkAbstractThe present data article describes high-school drop-out related web activities in Canada, from 2004 to 2012, obtained mining Google Trends (GT), using high-school drop-out as key-word. The searches volumes were processed, correlated and cross-correlated with statistical data obtained at national and province level and broken down for gender. Further, an autoregressive moving-average (ARMA) model was used to model the GT-generated data. From a qualitative point of view, GT-generated relative search volumes (RSVs) reflect the decrease in drop-out rate. The peak in the Internet-related activities occurs in 2004 (56.35%, normalized value), and gradually declines to 40.59% (normalized value) in 2007. After, it remains substantially stable until 2012 (40.32%, normalized value). From a quantitative standpoint, the correlations between Canadian high-school drop-out rate and GT-generated RSVs in the study period (2004–2012) were statistically significant both using the drop-out rate for academic year and the 3-years moving average.Examining the data broken down by gender, the correlations were higher and statistically significant in males than in females. GT-based data for drop-out resulted best modeled by an ARMA(1,0) model. Considering the cross correlation of Canadian regions, all of them resulted statistically significant at lag 0, apart from for New Brunswick, Newfoundland and Labrador and the Prince Edward island. A number or cross-correlations resulted statistically significant also at lag −1 (namely, Alberta, Manitoba, New Brunswick and Saskatchewan)
Piecewise linear value functions for multi-criteria decision-making
No full textMulti-criteria decision-making (MCDM) concerns selecting, ranking or sorting a set of alternatives which are evaluated with respect to a number of criteria. There are several MCDM methods, the two core elements of which are (i) evaluating the performance of the alternatives with respect to the criteria, (ii) finding the importance (weight) of the criteria. There are several methods to find the weights of the criteria, however, when it comes to the alternative measures with respect to the criteria, usually the existing MCDM methods use simple monotonic linear value functions. Usually an increasing or decreasing linear function is assumed between a criterion level (over its entire range) and its value. This assumption, however, might lead to improper results. This study proposes a family of piecewise value functions which can be used for different decision criteria for different decision problems. Several real-world examples from existing literature are provided to illustrate the applicability of the proposed value functions. A numerical example of supplier selection (including a comparison between simple monotonic linear value functions, piecewise linear value functions, and exponential value functions) shows how considering proper value functions could affect the final results of an MCDM problem.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport and Logistic

No full textMultimediju komunikācijaInformācijas un komunikācijas zinātnesMultimedia CommunicationInformation and Communication SciencesŠogad februārī tika atbrīvots Irānā prettiesiski ieslodzītais disidents Džafars Panahi, kura filmām uz politiskā režīma likto šķēršļu fona ir nozīmīga loma irāņu kino. Bakalaura darba “Autorkino iezīmes irāņu režisora Džafara Panahi filmās un sociālpolitiskais konteksts” mērķis bija noskaidrot raksturīgākās autorkino iezīmes Panahi kinodarbos, ņemot vērā kinodarbu sociālpolitisko kontekstu. Galvenie teorētiskie ietvari bija autorkino teorija, kino valoda (naratīvs, mizanscēna, operatora māksla, montāža, skaņa), irāņu kino (arī politika, sociālie procesi) un Panahi biogrāfija, filmogrāfija. Izmantojot kvalitatīvo kontentanalīzi, kvantitatīvo kontentanalīzi un kontekstuālo analīzi, darbā pētītas filmas “Baltais balons”, “Spogulis”, “Aplis”, “Tumšsarkanais zelts”, “Aizmugurē”, kā arī darbi, kas tapuši laikā, kad režīms autoram bija aizliedzis veidot filmas, proti, “Šī nav filma”, “Aizvērtais aizkars”, “Taksometrs” un “Trīs sejas”.
Pētījumā izdarīti vairāki secinājumi par Panahi kino raksturīgajām iezīmēm un filmu sociālpolitisko kontekstu. Par pirmo - kā piemērus var minēt viņa sarežģītos naratīvus, fikcijas un realitātes mijiedarbi, “ceturtās sienas” laušanu, Irānā aktuālo problēmu atspoguļojumu, kas balstīts reālās pieredzēs, notikumos, atvērtos finālus, simbolus, metaforas, alegorijas, cikliskumu, intertekstualitāti (t.sk. vizuālos citātus), marginalizētos varoņus, kas nav ļaunprātīgi un pastāvīgi tiek pakļauti sociālās vides ietekmei, filmēšanu reālās lokācijās, videokameras dieģetizēšanu, vardarbības klātbūtni bez nosakāma vardarbības avota, varoņu radītu inscenējumu, izmantojot mizanscēnu, neprofesionālos aktierus, kas tēlo sevi, garos plānus un augsto ASL (31 sekunde), apļveida kameras kustību, filmējumu ar dažāda veida kamerām lieguma laikā, nedieģētiskos iestarpinājumus u.c. Analizējot otro, atklāti sociālpolitiskie notikumi, kas klātesoši filmēšanas procesā vai iezīmēti filmās, sākot ar bērnu aktieriem, dzimumu un ekonomisko nevienlīdzību un beidzot ar represijām pret radošās industrijas pārstāvjiem.In February of this year, Jafar Panahi, a dissident illegally imprisoned in Iran, was released from prison. His films, made against the backdrop of obstacles imposed by the political regime, play an important role in Iranian cinema. The aim of the bachelor’s thesis “Features of auteur cinema in the films of Iranian director Jafar Panahi and socio-political context” was to find out the most characteristic features of auteur cinema in Panahi’s films, considering the socio-political context of these films. The main theoretical frameworks were auteur theory, the language of film (narrative, mise-en-scene, cinematography, montage, sound), Iranian cinema (also politics, social processes) and Panahi’s biography, filmography. By using qualitative content analysis, quantitative content analysis and contextual analysis, the thesis examines the films “The White Balloon”, “The Mirror”, “The Circle”, “Crimson Gold”, “Offside”, as well as works created when the author was banned from making films by the regime, namely “This Is Not a Film”, “Closed Curtain”, “Taxi” and “3 Faces”.
The research draws several conclusions about the characteristic features of Panahi’s cinema and the socio-political context of the films. About the former - as examples can be mentioned his complex narratives, interactions between fiction and reality, breaking of the fourth wall, representation of current issues in Iran based on real experiences, events, open endings, symbols, metaphors, allegories, cyclicality, intertextuality (including visual quotations), marginalized characters who are not evil and are constantly exposed to the influence of their social environment, filming in real locations, diegetization of the video camera, the presence of violence without an identifiable source, staging created by characters using mise-en-scene, non-professional actors playing themselves, long takes and high ASL (31 seconds), circular camera movement, filming with different types of cameras during the ban, nondiegetic inserts etc. By analyzing the latter, the socio-political events present in the filming process or marked in the films, starting with child actors, gender inequality, economic inequality and ending with repression against representatives of the creative industry, were revealed
