You are where you e mail: using e mail data to estimate international migration rates
Venue: WebSci '12
Year: 2012

International migration is one of the major determinants of demographic change. Although efforts to produce comparable statistics are underway, estimates of demographic flows are inexistent, outdated, or largely inconsistent, for most countries. We estimate age and gender specific migration rates using data extracted from a large sample of Yahoo! e mail messages. Self reported age and gender of anonymized e mail users were linked to the geographic locations (mapped from IP addresses) from where users sent e mail messages over time (2009 2011) The users' country of residence over time was inferred as the one from where most e mail messages were sent. Our estimates of age profiles of migration are qualitatively consistent with existing administrative data sources. Selection bias generates uncertainty for estimates at one point in time, especially for developing countries. However, our approach allows us to compare in a reliable way migration trends of females and males. We document the recent increase in human mobility and we observe that female mobility has been increasing at a faster pace. Our findings suggest that e mail data may complement existing migration data, resolve inconsistencies arising from different definitions of migration, and provide new and rich information on mobility patterns and social networks of migrants. The use of digital records for demographic research has the potential to become particularly important for developing countries, where the diffusion of Internet will be faster than the development of mature demographic registration systems.
CHLORINE CONSUMPTION MODELING AND TRIHALOMETHANE FORMATION POTENTIAL: KODIAT MDAOUAR DAM (BATNA, ALGERIA)
Year: 2013

Humic substances are the most widely distributed organic products of surface water, they are known by their strong reactivity with chlorine, producing trihalomethanes (THM) THM are classified as carcinogenic compounds that are regulated by the world health organization and other government organizations (CEE, US EPA) After a succession of operations: filtration, softening and concentration with reverse osmosis, Hydrophobic and transphilic fractions of natural organic matter (NOM) were isolated from water supplies (Koudiat Medaour dam Batna) using no polar XAD 7HP and XAD 4 resin. Under standard conditions (pH 7.0 0.2, 25deg C) hydrophobic (HPO) and transphilic (TRS) fractions, are chlorinated with an excess of sodium hypochlorite, then chlorine consumption and UV254 variation are followed. The obtained results were modeled by nonlinear regression using XLStat pro 7.5 software. After seven days of chlorination, the trihalomethanes formation potential (THMFP) was analyzed using gas chromatography LLE GC ECD. The results show that the chlorine consumption of HPO and TRS fractions are practically similar and their values are 1.106 and 1.235 mg Cl2/mg C respectively. On the other hand, the formation of THMFP of TRS fraction (59.62 mg THM/mg C) was more important than that of HPO fraction (32.817mg THM/mg C) The chlorine consumption model confirms the first order with two speeds, the fast speed from 0 to 2 hours and the slow speed from 2 to 168 hours. The characterization of functional groups by infrared (FTIR) shows more important carboxylic and phenolic functions in the transphilic fraction than in hydrophobic fraction, this is in correlation with the strong reactivity of the transphilic fraction compared to that of hydrophobic fraction.
The Impact of COVID 19 Crisis on Medium sized Enterprisesin Serbia
Year: 2020

The research objective is to empirically assess the impact of the COVID 19 crisis on the operation of medium sized enterprises in Serbia. The main research question is how the COVID 19 crisis has affected the operation of medium sized enterprises in Serbia with focus on major problems faced by these enterprises in times of the state of emergency over the epidemic. Also, considerable research attention is on policy measures to alleviate the negative impact of the COVID 19 outbreak with comparison of measures between Serbia and selected countries. To empirically assess the impact of the COVID 19 crisis on medium sized enterprises in Serbia, an online survey research was conducted during the period of March and April 2020. The survey results show that the COVID 19 crisis has affected the daily business of medium sized enterprises in different ways and with varying intensity. Due to the COVID 19 outbreak, 20% of the surveyed enterprises have moved their employees to work from home, while a decline in liquidity and in business capacity utilization, as well as supply chain disruptions have occurred in 16% of enterprises each. Less than 10% of enterprises expressed other problems such as payment of wages, insufficient workforce utilization, reduction in business hours, production disruptions, limited access to resources etc.
Proposal for the integration of the semantic structure of Wikipedia categories into Wikidata using SKOS
Year: 2018

DBpedia is the most prominent dataset in Linked Open Data ecosystem. Wikidata is a Wikimedia movement initiative to represent knowledge as data, structured, defined and maintained collaboratively. Both are cross domain Open Knowledge Graphs. WikiData is intended to change the way in which data is used by the Wikimedia editors, and it will probably have influence in how DBpedia data is collected. So, improving the semantic of Wikipedia Categories in Wikidata will have a deep impact in Knowledge Organization. In this work we propose a methodology for the SKOS integration into de WikiData data model of the Wikipedia Category semantic structure. An analytic comparative report of how Wikipedia categories are treated in DBpedia and WikiData is conducted, including not only the terms itself, but also their relationships and correspondences. Equivalence patterns between the objects or entities of the three sources Wikipedia, DBpedia and Wikidata are identified. Other content elements, such as articles, participation records or external links are also take in consideration. Then, keeping in mind the autodescriptive nature of WikiData infrastructure a set of entities and properties that allow the use of SKOS to represent semantic relationships are suggested. Last, we have designed and tested a methodology for the automatic design of an automatic process of reuse of semantic representation of semantic relations in Dbpedia. The proposal details the SKOS properties and classes that should be included as WikiData entities, in order to represent categories semantic relationships and its mappings and cross references with other SKOS datasets. Technical advice of how obtain and adapt DBpedia categories RDF statements in order to be incorporated in WikiData is exposed. This methodology, whose results are a kind of alignment between DBpedia and WikiData categories, is built upon the matching between their different representations. A bunch of tasks, procedures and tools are developed, that allow manage not only concepts, but also SKOS labels and semantic relationships existing in Dbpedia. Adding semantic relationships of Wikipedia categories in Wikidata is viable, and DBpedia is a worthy tool for do this. Including semantic relationships in Wikidata improve its quality as a Knowledge Organization resource. Wikidata categories, whose source is Wikipedia, may be used as an element to align thesauri, subject headings, taxonomies, etc. Due this reason, apply SKOS in category representation could be the first step for Wikidata not only to be a factual database, but also a knowledge organization platform.
Automatic Synthesis of Robust and Optimal Controllers An Industrial Case Study
Venue: HSCC
Year: 2009

In this paper, we show how to apply recent tools for the automatic synthesis of robust and near optimal controllers for a real industrial case study. We show how to use three different classes of models and their supporting existing tools, Uppaal TiGA for synthesis, phaver for verification, and Simulink for simulation, in a complementary way. We believe that this case study shows that our tools have reached a level of maturity that allows us to tackle interesting and relevant industrial control problems.
Virtual Radicalisation: Challenges for Police
Year: 2007

Recent advances in communications technology are providing a medium for individuals or groups to subscribe to extremist worldviews and form networks, access training and obtain information, whilst remaining virtually undetected in the online world. Whilst the Internet is facilitating global virtual communities like Second Life, MySpace and Facebook it is also providing an anonymous meeting place for disenfranchised individuals to gather, share ideas, post and exchange information regarding their particular ideology. This virtual community provides a sense of belonging to a global cause in which the actions of an individual can be aligned to, and seen to contribute towards something more significant than their own lives. Membership of this virtual community can facilitate the indoctrination of individuals, thereby negating psychological barriers that would normally inhibit particular types of behaviour. Terrorist groups operate as amorphous, fluid networks providing them significant advantages over rigidly structured state and nation based law enforcement agencies. In addition terrorist groups are exploiting the combination of rapidly evolving technology and incommodious legislation to prevent detection.
Highly luminescent N doped carbon dots as a fluorescence detecting platform for Fe3+ in solutions and living cells.
Venue: The Analyst
Year: 2020

Iron (Fe3+ is one of the most essential elements in the human body; deficiency or overdose of Fe3+ may have adverse effects on human health and immunity. Hence, it is essential to establish a sensitive and selective method for ion detection. In this study, novel green fluorescent N doped carbon dots (N CDs) were prepared with caffeic acid as the carbon source via a simple hydrothermal method. The solution of the as prepared N CDs exhibits 21.5% quantum yield, good salt stability, excellent water solubility, low cytotoxicity and good photobleaching resistance. The N CDs can be used as a fluorescent probe for the detection of Fe3+ ions in aqueous solutions and bioimaging in living cells.
Posture verbs A multilingual contrastive study
Year: 2013

From a typological perspective, the verbs of sitting, standing and lying have been described relatively extensively. Against this background, the present paper provides a contrastive study of the lexical semantics of the Swedish posture verbs sitta 'sit' sta 'stand' and ligga 'lie' based on the Multilingual Parallel Corpus (MPC) which contains extracts from Swedish novels and their published translations into English, German, French and Finnish. Since the corpus is a very rich data source, the study is focused on the use of posture verbs as locative verbs. It turns out that it is possible to arrange the languages along a continuum with respect to the use of posture verbs versus the copula to describe the location of inanimate objects. In Finnish the copula dominates completely, in English there is more of a balance (in this kind of written text) whereas the posture verbs dominate in German and Swedish. French stands out as a completely different type in this comparison, since the copula is used very little and posture verbs hardly at all. Actually, there is a tension in French between the use of a small number of verbs with a general locative meaning as translations and the use of a large variety of reflexive verbs and resultative constructions with past participles (e.g. etre fixe 'be attached' which convey fine grained information about the placement. Among the languages that use posture verbs as locative predicates, there is a general similarity with respect to the factors that condition the choice between lie and stand, whereas even closely related Germanic languages differ with respect to the semantic factors that condition the choice of sit as a locative predicate.
Fabrication and environmental assessment of photo assisted Fenton like Fe/FBC catalyst utilizing mealworm frass waste
Year: 2020

The massive generation of dye wastewater and mealworm waste has shown potential dangers. In this study, an innovative method was developed to fabricate an efficient photo assisted Fenton like heterogeneous catalyst, namely, iron (Fe) loaded mealworms (the larvae of Tenebrio molitor Linnaeus) frass based biochar (Fe/FBC) The physico chemical properties were characterized by X ray powder diffraction, scanning electron microscopy, energy dispersive X ray spectroscopy, X ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, Brunsuer Emmett Teller, Raman spectroscopy, inductively coupled plasma spectroscopy, and N2 sorption desorption isotherms. The results revealed the successful loading of Fe(III) on Fe/FBC surface with a loaded content of 6.0 wt% and increased graphitization degree with high surface area (90.65 m2 g 1) appeared in Fe/FBC. Excellent removal efficiency toward malachite green (MG) dye (67% TOC within 5 min) and good recycling performance of Fe/FBC were observed in photo assisted heterogeneous Fenton like system, indicating that the aid of light irradiation may accelerate the heterogeneous Fenton like reaction and realize the synergistic effect of enhanced MG degradation. Three key possible MG degradation pathways, involving N de methylation, hydroxylation, and destruction of the conjugated chromophore, were proposed based on the results of ultra performance liquid chromatography tandem mass spectrometry. Life cycle assessment study was applied to evaluate the environmental impacts of the following two disposal strategies for frass wastes: Fe/FBC catalyst facilitation (scenario A) and composting treatment (scenario B) at midpoint level. Regarding ten impact categories, scenario A produced lower environmental footprint compared to scenario B, indicating that the facilitation of Fe/FBC is a financially and environmentally viable strategy for relieving the greenhouse effect, energy crisis, water toxicity, and eutrophication.
In The Moment Dissociation, Emotional Numbing, and Sexual Risk: The Influence of Sexual Trauma History, Trauma Symptoms, and Alcohol Intoxication.
Venue: Psychology of violence
Year: 2016

Prior research on the effects of sexual trauma has examined dissociation but not emotional numbing during sex and has relied exclusively on retrospective surveys. The present experiment examined associations among distal factors of childhood sexual abuse (CSA) adolescent/adult sexual assault (ASA) and trauma symptoms and the proximal factor of acute alcohol intoxication on in the moment dissociation, emotional numbing, and sexual risk intentions.  Young adult female drinkers (N 436) at elevated sexual risk were randomized to receive alcohol (target peak breath alcohol concentration .10% or no alcohol. They then read an eroticized sexual scenario and reported on their dissociation and emotional numbing experiences, unprotected sex refusal self efficacy, and unprotected sex intentions.  Path analysis revealed that CSA was indirectly associated with increased unprotected sex intentions through increased ASA severity, increased trauma related symptoms, increased emotional numbing, and decreased unprotected sex refusal self efficacy. Further, alcohol intoxication was indirectly associated with increased unprotected sex intentions through increased emotional numbing and decreased unprotected sex refusal self efficacy.  Emotional numbing, but not dissociation, was associated with unprotected sex intentions and may be one potential target for interventions aimed at reducing HIV/STI related risk among women with a history of sexual trauma.
A decentralized lightweight blockchain based authentication mechanism for IoT systems
Venue: Cluster Computing
Year: 2020

The Internet of Things (IoT) is an emerging paradigm branded by heterogeneous technologies composed of smart ubiquitous objects that are seamlessly connected to the Internet. These objects are often deployed in open environments to provide innovative services in various application domains such as smart cities, smart health, and smart communities. These IoT devices produce a massive amount of confidentiality and security sensitive data. Thus, security of these devices is very important in order to ensure the safety and effectiveness of the system. In this paper, a decentralized authentication and access control mechanism is proposed for lightweight IoT devices and is applicable to a large number of scenarios. The mechanism is based on the technology of the fog computing and the concept of the public blockchain. The results gained from the experiments demonstrate a superior performance of the proposed mechanism when compared to a state of the art blockchain based authentication technique.
Digital capitalism and the e health revolution
Year: 2021

This paper discusses the challenges posed by the advent of e health. To contextualise the phenomenon, it defines the environment in which it arises: digital capitalism. The predatory dynamics of this social structure are likely to transform medical practice. Contemporary medicine seems to be poised between a renewed attention to the patient and their dignity perspective of the medical humanities and the reduction of the patient to a mere object of study and discipline biomedicine. By favouring the quantification of the patient and a depersonalising approach, digital medicine risks breaking the bond between these two sides of medicine. At the same time, the development of medical technologies in a capitalist environment poses other risks that need to be weighed up: from the gratuitous appropriation of personal data to the creation of a discriminatory and classist healthcare system. Only by openly addressing these problems will it be possible to integrate these new technologies in a democratic way that promotes the common good.
Sensory evaluation of a body lotion formulated with hot spring water from Deokgu, Korea
Year: 2019

The purpose of this study was to evaluate hot spring water (HSW) from Deokgu as a cosmetic ingredient in the preparation of a body lotion. The HSW was tested for its suitability as an aqueous phase main component. Microbiological and chemical stability tests of the HSW were carried out. Microorganisms including E. coli were not detected or detected below the detection limits, and no harmful heavy metals were found. The cytotoxicity of the HSW was also considered, and its pH determined over a period of three months. Further, sensory characteristics were assessed for consumer acceptance by performing sensory tests on body lotions formulated using either Deokgu HSW or distilled water. Skin moisturization, irritation and tension reinforcement were found to be enhanced when using the HSW lotion rather than that formulated with distilled water. Taken together, the results of this study show that the use of HSW in cosmetic formulations contributes to the efficacy of these products. yo yag iyeonguyimogjeogeunbadirosyeonjejosihwajangpumceomgajeroseoyideogguonceonsureulpyeonggahagiwihamida. juyosuyongseongguseongseongbuneu roseoyi onceonsuyi jeoghabseongeul siheomhayeossda. onceonsuyi misaengmul mic hwahagjeog anjeonseong siheomi suhaengdoeeossda. daejanggyuneul biroshan misaengmuleun geomculdoejianhassgeonageomculhandoiharogeomculdoeeosseumyeo, yuhaehanjunggeumsogeunjeonhyeogeomculdoejianhassda. onceonsuyisepodogseongipyeonggadoeeosseu myeo, onceonsuyi pH byeonhwareul 3daldonganceugjeonghayeossda. ddohandeogguonceonsumicjeungryusurojejodoenbadirosyeonedaehaeseogwanneungsiheomeulsuhaenghameu rosseo sobijayi jeoghabseongeul gwanneungteugseong bunseogeul tonghayeo pyeonggahayeossda. jeungryusuro jejodoen badirosyeonboda onceonsureul sayonghan badirosyeoneul pibue jeogyonghayeosseulddae, pibuboseub, pibuteureobeulmic pibu jangbyeogganghwaga jeungjindoeeossda. jonghabhae boasseul ddae, i yeonguyi gyeolgwaneun hwajangpum jejoe isseoseo onceonsureul sayonghaneun geoseun hwajangpumyi hyoneungeul jeungjinsikil su isseumeul boyeo junda.

This interactive panel will consist of five short presentations from each of the panelists and a moderated Q&A led by moderator, Jenna Hartel. The panelists each share some examples of their recent work studying fun life contexts, reflect on their experience researching in a new domain, and develop themes and questions that should be addressed in future work.
Multiple UAVs as Relays: Multi Hop Single Link Versus Multiple Dual Hop Links
Venue: IEEE Transactions on Wireless Communications
Year: 2018

Unmanned aerial vehicles (UAVs) have found many important applications in communications. They can serve as either aerial base stations or mobile relays to improve the quality of services. In this paper, we study the use of multiple UAVs in relaying. Considering two typical uses of multiple UAVs as relays that form either a single multi hop link or multiple dual hop links, we first optimize the placement of the UAVs by maximizing the end to end signal to noise ratio for three useful channel models and two common relaying protocols. Based on the optimum placement, the two relaying setups are then compared in terms of outage and bit error rate. Numerical results show that the dual hop multi link option is better than the multi hop single link option when the air to ground path loss parameters depend on the UAV positions. Otherwise, the dual hop option is only better when the source to destination distance is small. Also, decode and forward UAVs provide better performances than the amplify and forward UAVs. The investigation also reveals the effects of important system parameters on the optimum UAV positions and relaying performances to provide useful guidelines.
