Istraživanje je sprovedeno s ciljem izdvajanja uloga učesnika u elektronskom maltretiranju, posebno uloge svedoka koja je u prethodnim istraživanjima često zanemarivana. Drugi cilj je bio ispitivanje ...nekih faktora rizika od uključenosti u elektronsko maltretiranje, a s obzirom na pripadnost određenoj ulozi u elektronskom maltretiranju. Uzorak je obuhvatio 285 učenika iz Sremske Mitrovice (141 mladić, 144 devojaka), uzrasta od 15 do 19 godina. U istraživanju je korišćen Revidiran inventar elektronskog maltretiranja (RCBI), zajedno sa kratkim upitnikom kojim se meri način i dužina vremena provedenog na internetu i roditeljska uključenost u vreme provedeno na internetu. Pored toga, primenjena je i kratka forma inventara Velikih pet plus dva za ispitivanje bazičnih dimenzija ličnosti. Na osnovu skorova na RCBI, ispitanici su podeljeni u pet grupa, odnosno uloga: oko 40% ispitanika ne učestvuje u maltretiranju ni na koji način, 14.7% ispitanika su svedoci, a za oko 45% ispitanika se može reći da su uključeni u maltretiranje kao nasilnici (6%), žrtve (13%) i nasilnici-žrtve (26%). U cilju predikcije pripadnosti nekoj od sačinjenih grupa, na osnovu određenih karakteristika ponašanja na internetu, roditeljske kontrole i osobina ličnosti, primenjena je multinominalna logistička regresija. Iako je model značajan, sve grupe se međusobno značajno ne razlikuju po ispitivanim varijablama. U odnosu na grupu adolescenata koji nisu uključeni u elektronsko maltretiranje, grupa nasilnika većinu vremena za računarom provodi na društvenim mrežama, uz višu roditeljsku kontrolu vremena provedenog na internetu. Grupa žrtava se ne razlikuje značajno od grupe neuključene u maltretiranje po ispitivanim varijablama, dok grupa svedoka izveštava o nižoj kontroli i interesovanju roditelja za vreme provedeno na internetu. Grupu nasilnika-žrtava karakteriše veći broj mladića, viša negativna valenca, niži neuroticizam i veća roditeljska kontrola/ograničavanje vremena provedenog na internetu.
Der wachsende Einfluss der Internetplattformen des 21. Jahrhunderts in wirtschaftlicher, gesellschaftlicher und politischer Hinsicht hat eine Diskussion über die angemessene Regulierung dieser ...Konzerne ausgelöst. Im Zentrum dieser Debatte steht das Kartellrecht – das Rechtsgebiet, das zur Kontrolle marktbeherrschender Unternehmen geschaffen wurde. Die Bestimmung des im Kartellrecht fundamentalen Begriffes der marktbeherrschenden Stellung steht in der Rechtsanwendung bei Internetplattformen vor zahlreichen Herausforderungen, von der Unentgeltlichkeit der Leistungen bis hin zur Mehrseitigkeit der Geschäftsmodelle. Die vorliegende Arbeit zerlegt den Begriff der marktbeherrschenden Stellung in seine Teile und zeigt auf, inwiefern die Methodik einer Anpassung an die digitale Wirtschaft bedarf. Dies geschieht unter Einbeziehung der Erkenntnisse der Rechtsökonomie sowie der Rechtsordnungen Deutschlands, der Europäischen Union und der USA.
Wohin entwickelt sich die Konsumgesellschaft? Wie ändern sich die Einstellungen und Verhaltensweisen der Verbraucherinnen und Verbraucher? Zeichnet sich ein Wandel vom industriellen Massenkonsum zum ...individualisierten Digitalkonsum ab? Diesen Fragen widmete sich die dritte Jahrestagung des bundesweiten Netzwerks Verbraucherforschung, deren Ergebnisse der vorliegende Band dokumentiert. Tiefgreifende Transformationen in der Geschichte des Konsums, wie sie die Industrielle Revolution und die Digitalisierung darstellen, können nur durch disziplinübergreifende Forschungsanstrengungen verstanden werden. Neben den klassischen Fächern der Verbraucherwissenschaften wie Wirtschafts-, Rechts-, Politik- und Sozialwissenschaften kommen daher in diesem Band auch historiografische und kulturwissenschaftliche Perspektiven zum Tragen. Die Veröffentlichung hat zum Ziel, den Austausch aktueller Ergebnisse der verbraucherbezogenen Forschung in Wissenschaft und Politik zu fördern und den Wissenstransfer zu stärken.

Provider: - Institution: - Data provided by Europeana Collections- E-learning is a complex system which includes distance learning, lectures,
and classroom materials in various electronic forms; both ...individual and
group learning process, tutor and interactive work. A significant and rapid
increase in the number of users, services, educational content and resources
required, face educational institutions and their e-learning systems with new
challenges of optimization of singling resources out, with the demands of
dynamic competitiveness and with the control of expenses of such systems. All
this leads to the fact that the demands for development and implementation of
IT infrastructure for e-learning systems are becoming more complex. By
applying modern information and communication technologies, it is possible to
increase efficiency, flexibility and cost-effectiveness of e-learning
systems. Through introducing models of IT infrastructure for e-learning based
on a contemporary IT concept of Cloud Computing, the reliability, scalability
and cost-effectiveness of a system of educational processes could be
improved. Insufficient development of scientific support in the application
of the Cloud Computing concept in modeling the IT infrastructure of higher
education of the Republic of Serbia and the strategic importance of this
concept indicates the need to establish theoretic support for its more
efficient development and application. With regards to this, the subject of
the dissertation research is presented, based on defining and development of
plans and activities of higher education institutions, related to the
development of IT infrastructure model for e-learning by means of Cloud
Computing concept. Through examining the existing and searching for new ways
of providing services to students and scientific research staff, higher
education institutions are faced with a significant number of challenges,
mainly regarding digital identity and access management. The first and
probably the greatest challenge is to prompt adoption and implementation of
digital identity management systems. Successful IT infrastructure for digital
identity management requires systematic thinking about identities and
interdependence which exists between them. The second challenge is to provide
support for a system which would be able to use all advantages of federation
systems for digital identities management. The development of such
federations among educational institutions enables mobility of users, content
and services. The main hypothesis devised and proven within the doctoral
thesis is that the application of a developed IT infrastructure model can
influence the efficiency and cost-effectiveness of e-learning systems. The
experimental part of the doctoral thesis is consisted of a research, directed
towards the validation of the proposed IT infrastructure model for
e-learning. Research was conducted in the Laboratory for E-Business at the
Faculty of Organizational Sciences. The results of the research showed that
the implemented model of IT infrastructure enabled the system of e-learning
to be more efficient, flexible and more economical.- Elektronsko obrazovanje je kompleksan sistem koji uključuje učenje na
daljinu, predavanja na daljinu, nastavne materijale u raznim elektronskim
formama, individualni i grupni proces učenja, tutorski i interaktivni rad.
Ogroman i brzi rast broja korisnika, usluga, obrazovnih sadržaja i potrebnih
resursa, suočavaju obrazovne ustanove i njihove sisteme elektronskog
obrazovanja sa izazovima optimizacije izdvajanja resursa, zahtevima dinamičke
konkurentnosti i sa kontrolom troškova ovakvih sistema. Sve ovo dovodi do
toga da su zahtevi za projektovanje i implementaciju IT infrastrukture
sistema za elektronsko obrazovanje sve kompleksniji. Primenom savremenih
informaciono-komunikacionih tehnologija moguće je doprineti povećanju
efikasnosti, fleksibilnosti i ekonomičnosti sistema za elektronsko
obrazovanje. Uvođenjem modela IT infrastrukture za elektronsko obrazovanje,
zasnovanog na savremenom IT konceptu Cloud Computing-a, mogu se unaprediti
obrazovni procesi sa stanovišta pouzdanosti, skalabilnosti i ekonomičnosti
sistema. Nedovoljno razvijena naučna podrška primene koncepta Cloud
Computing-a u modelovanju IT infrastrukture u visokoškolskom obrazovanju
Republike Srbije i strateška važnost ovog koncepta, ukazuje na potrebu
postavljanja teorijske podrške njegovog efikasnijeg razvoja i primene. U tom
smislu je i predstavljen predmet istraživanja disertacije, koji se bazira na
definisanju i razvijanju planova i aktivnosti visokoškolskih ustanova,
vezanih za razvoj modela IT infrastrukture za elektronsko obrazovanje pomoću
Cloud Computing koncepta. Preispitujući postojeće i tražeći nove načine
pružanja usluga studentima i naučno-istraživačkom osoblju, visokoškolske
ustanove se suočavaju sa velikim brojem izazova uglavnom oko digitalnog
identiteta i upravljanja pristupom. Prvi i možda najveći izazov je kako da se
podstakne usvajanje i implementacija sistema za upravljanje digitalnim
identitetom. Uspešna IT infrastruktura za upravljanje digitalnim identitetom
zahteva celovito razmišljanje o identitetima i međuzavisnostima koje između
njih postoje. Drugi izazov je izgradnja podrške za sistem koji će moći da
iskoristi sve prednosti saveza sistema za upravljanje digitalnim
identitetima. Stvaranjem ovakvih saveza između obrazovnih ustanova obezbeđuje
se mobilnost korisnika, sadržaja i usluga. Glavna hipoteza koja je razvijena
i dokazana u okviru doktorske disertacije je da se primenom razvijenog modela
IT infrastrukture može uticati na efikasnost i ekonomičnost sistema za
elektronsko obrazovanje. U eksperimentalnom delu doktorske disertacije
realizovano je istraživanje usmereno ka validaciji predloženog modela IT
infrastrukture za elektronsko obrazovanje. Istraživanje je sprovedeno u
Laboratoriji za elektronsko poslovanje Fakulteta organizacionih nauka.
Rezultati istraživanja pokazali su da implementirani model IT infrastrukture
omogućava da sistem za elektronsko obrazovanje bude efikasniji, fleksibilniji
i ekonomičniji.- All metadata published by Europeana are available free of restriction under the Creative Commons CC0 1.0 Universal Public Domain Dedication. However, Europeana requests that you actively acknowledge and give attribution to all metadata sources including Europeana
