Digitalno vladovanje, ki se razvija v državah članicah EU kot odgovor na izzive avtomatiziranega in algoritmiziranega komuniciranja ob ujetosti državne in evropske medijske regulacije v analogne ...koncepte in rešitve, je zaradi kompleksnosti redko predmet celostne obravnave. Predlagan metodološki pristop, utemeljen na konceptu vladovanja in splošni teoriji sistemov, ki povezuje družbene, ekonomske in tehnične koncepte, ter obseg primerjalne raziskave, ki vključuje 24 držav članic EU, omogočata celovit vpogled v stanje vladovanja v EU. Rezultati raziskave so predstavljeni v kontekstu procesov transformacije regulacije in vladovanja ter širših medijskih in družbenih sprememb, pri katerih se zdi, da je regulacija vedno nekaj korakov za tehnološkimi podjetji, zdaj že pomembnimi globalnimi političnimi akterji, kot v igri mačke in miši, v kateri bi morale države pokazati več spretnosti, odločnosti in sodelovanja, korporacije pa več družbene odgovornosti.
Cilj ovog istraživanja bio je utvrditi koje su strategije kognitivne emocionalne regulacije najzastupljenije na uzroku adolescena-ta, na koji su način one povezane sa indikatorima mentalnog zdravlja ...adolescenata, te da li se veza između strategija kog-nitivne regulacije emocija i globalnog subjektivnog blagostanja ostvaruje direktno, ili preko pozitivnog i negativnog afektiviteta. Istraživanje je obavljeno na uzorku 206 učenika prosečnog uz-rasta 16 godina. Rezultati su pokazali da su kod adolescenata najzastupljenije strategije pozitivna reformulacija i stavljanje u perspektivu, koje su, zajedno sa planiranjem i pozitivnim refokusiranjem, povezane sa pozitivnim merama mentalnog zdravlja (globalnim subjektivnim blagostanjem adolescenata i pozitivnim afektivitetom). Ruminacija, katastrofiziranje, samookrivljavanje, i u manjoj meri prihvatanje, su povezane sa negativnim afektivitetom. Analizom medijacije izdvojile su se dve strategije kognitivne emocionalne regulacije koje značajno predviđaju subjektivno blagostanje: pozitivna preformulacijai samo-okrivljavanje. Utvrđeno je da se veza između pozitivne preformulacije i subjektivnog blagostanja ostvaruje delimično direktno, a delimično je posredovana pozitivnim afektivitetom kao medijatorom. Rezultati istraživanja takođe su pokazali da se veza između samookrivljavanja i globalnog subjektivnog blagostanja ostvaruje isključivo indirektno - preko negativnog afektiviteta kao medijatora. U svetlu dobijenih rezultata, formulisane su neke praktične implikacije za preventivni i in-terventni rad sa adolescentima u cilju povećanja subjektivnog blagostanja.
Pandemija bolesti COVID-19 utjecala je na sve segmente društva pa tako i na medije. Narušavanje ukupne ekonomije utjecalo je na ekonomsko poslovanje medija, ali i na kvalitetu programskih sadržaja ...jer su društvene aktivnosti reducirane uslijed niza mjera kojima se sprječava širenje virusa. Mediji gotovo da nisu imali o čemu izvještavati ako to nisu bile teme vezane za pandemiju i, dakako, političke teme. Cilj je ovog rada procijeniti koliko je pandemija utjecala na ukupno poslovanje elektroničkih medija u Republici Hrvatskoj. Prije svega, u teorijskom je dijelu rada bilo riječi o samoj medijskoj regulaciji općenito te u Hrvatskoj, kao i aktivnostima koje su poduzete kako bi negativan utjecaj pandemije na hrvatske elektroničke medije bio što manji. U drugom dijelu rada predstavljeni su rezultati istraživanja koje su proveli autori ovog rada u okviru Agencije za elektroničke medije upravo kako bi se dobila jasnija slika o utjecaju pandemije. Kvantitativno istraživanje, online anketa, provedeno je u siječnju 2021. godine među pružateljima različitih elektroničkih medija koji su upisani u Upisnik pružatelja medijskih usluga, elektroničkih publikacija i neprofitnih proizvođača audiovizualnog i radijskog programa, a koji vodi Agencija za elektroničke medije. Istraživanjem su prikupljeni podaci o financijskom utjecaju pandemije, ali i o njezinu utjecaju na kvalitetu programa pružatelja medijskih usluga. Isto tako, autori su istraživanjem dobili informacije o broju zaposlenika u ispitanim medijima koji su bili zaraženi virusom COVID-19 te broju preminulih, kao i podatke tj. ocjenu medija o načinu kako su sami mediji informirali javnost o pandemiji i kako su mjerodavne institucije informirale medije o pandemiji.
The pandemic caused by the COVID-19 virus has affected all segments of society, including the media. The threat to the overall economy likewise endangered the economic operations of media, but it has also affected the quality of their programme contents since social activities were reduced by a series of measures undertaken to prevent the spread of the virus. Media had almost nothing to report on except for pandemic-related topics and, obviously, political topics. The aim of the present paper is to analyse the impact of the pandemic on the overall business of electronic media in the Republic of Croatia. First, in the theoretical part of the paper, we discussed media regulation in general and in Croatia as well as the activities undertaken to minimize the negative impact of the pandemic on Croatian electronic media. The second part of the paper presents the results of a research conducted by the paper’s authors as a part of their work in the Agency for Electronic Media. The aim of the research was to get a better understanding of the pandemic’s impact. The quantitative research, an online survey, was conducted in January 2021 among providers of various electronic media, registered in the Registry of Media Service Providers, Electronic Publications and Non-profit Producers of Audio-visual and Radio Programmes, kept by the Agency for Electronic Media. The research collected data on the financial impact of the pandemic, as well as on its impact on the quality of media service providers’ programme contents. The authors also obtained data on the number of employees of the media which participated in the research who were infected by the COVID-19 virus, including the number of the deceased, as well as the information i.e. assessment of the media on how media themselves informed the public about the pandemic as well as how the relevant institutions informed media about the pandemic.
Nova euroatlanska civilizatorska misija u hrvatskom prostoru objašnjava se nesposobnošću hrvatske političke vlasti da sama upravlja svojim prostorom, s obzirom na unutarnje etničke netrpeljivosti i ...nejedinstvo te posljedični manjak samosvijesti zbog koje joj je nužna zaštita Europske unije i NATO-a. Sistemska regulacija međudržavnih odnosa u hrvatskom prostoru tako se je ponovno zatekla u škripu hrvatskog identitarnog bipolarizma, koji počiva na dvama naizgled oprečnim hrvatskim idealima (vjerskom i nacionalnom). Stoga se dobiva dojam da dvije hrvatske tendencije, pripadnost oksidentalnoj vjerskoj, ali slavenskoj zajednici naroda, ne mogu djelovati simultano, nego samo naizmjenično. Iako je upravo jednostrana, naizmjenična eksploatacija hrvatskog dualnog identiteta izvor je svih tragedija Hrvata modernog doba.
Iako je ovaj članak namijenjen svim dionicima supervizijskog procesa, kao što su to supervizanti i donositelji odluka o provođenju supervizije na različitim organizacijskim razinama, prvenstveno je ...namijenjen supervizorima. Kao i drugdje u svijetu, zbog korona epidemije, supervizori u Hrvatskoj trenutno su suočeni s nužnosti provođenja različitih oblika podržavajuće supervizije namijenjene stručnjacima i volonterima koji rade s ranjivim skupinama stanovništva. Istodobno, specifično za Hrvatsku, supervizori se suočavaju s nužnosti korištenja supervizije “na daljinu” koja je novina u nas. Polazeći od analize međunarodnih iskustva te naših početnih iskustava, ponuđene su prve u smjernice za “početnike” za planiranje i provođenje online supervizije. Problematizirani su etički i pravni aspekti zaštite supervizanata i njihovih klijenata/korisnika, IT aspekti i praktični aspekti supervizijskog rada online. Također su opisana obilježja podržavajuće supervizije, uključujući emocionalnu regulaciju u supervizijskom procesu, koji je u doba korona epidemije nužno online.

Although the suburb of the civitasof Dubrovnik has been a frequent scho-larly topic since the middle of the twentieth century, current researchers are still faced with numerous doubts and ...obscurities. Dating of the city’s expansi-on north of the Strossmayer Street, location of the muro novo civitatis versus montem, as well as the regulation of streets by the Statute of Dubrovnik of 1272 are merely some of the issues discussed in this article. The area of the civitas as described by Constantine Porphyrogenitus (Ca-strum, St. Peter and Pustijerna), which existed on the peninsula in the middle of the tenth century, was being gradually joined to the opposite mainland - to-day’s Prijeko - by filling a deep, partly swampy bay. Filling of the marshland was an essential precondition for the city’s expansion to the north. By 1255, plots and houses north of the Strossmayer Street were already protected by the new city wall. Archival documents offer evidence for its ubication along today’s GučetićStreet. The position of the city gates determined the layout of some streets that had existed even before 1272, when they were regulated by the Statute (Ulica od Domina, St. Joseph’s, Miho Pracat’s, Lučarica). Certain con-troversies surrounding the interpretations of Book V, Chapter XLI and Book VIII, Chapter LVII of the Statute of Dubrovnik of 1272, and its amendment of 1296 by which the streets south of the Placa were regulated, prompted the authors of this article to a detailed analysis of the provisions and their interpre-tations to date. This has led to a new interpretation of some provisions, but also to an assumption of the existence of several streets which became void over time. Documents published in the Spisi dubrovačke kancelarijehave allowed a precise location of the plots and houses mentioned in the Statute.
An insightful look at how to reform our broken financial systemThe financial crisis that unfolded in September 2008 transformed the United States and world economies. As each day's headlines brought ...stories of bank failures and rescues, government policies drawn and redrawn against the backdrop of an historic Presidential election, and solutions that seemed to be discarded almost as soon as they were proposed, a group of thirty-three academics at New York University Stern School of Business began tackling the hard questions behind the headlines. Representing fields of finance, economics, and accounting, these professors-led by Dean Thomas Cooley and Vice Dean Ingo Walter-shaped eighteen independent policy papers that proposed market-focused solutions to the problems within a common framework. In December, with great urgency, they sent hand-bound copies to Washington. Restoring Financial Stabilityis the culmination of their work.Proposes bold, yet principled approaches-including financial policy alternatives and specific courses of action-to deal with this unprecedented, systemic financial crisisCreated by the contributions of various academics from New York University's Stern School of BusinessProvides important perspectives on both the causes of the global financial crisis as well as proposed solutions to ensure it doesn't happen againContains detailed evaluations and analyses covering many spectrums of the marketplaceEdited by Matthew Richardson and Viral Acharya, this reliable resource brings together the best thinking of finance and economics from the faculty of one of the top universities in world.
The southern periphery area appeared in the city government’s development plans in the late 19th century, and was envisioned as an industrial and recreative area that would include a port on the ...river Sava. Its value as a residential area was foreseen only in the Main Regulatory Plan of 1930/31, which was approved in 1940. The lack of a regulatory basis for this area was the consequence of the unregulated flow of the Sava, whose annual flooding remained a threat, and also of the railway to the north, which cut the area off from the Lower Town and city centre. This so-called ‘Railway Question’ burdened the city government for decades after the erection of the Main Railway Station building in 1892, though it was somewhat ameliorated by the construction of an underpass on Miramarska Road in 1913. The separation of the southern periphery from the city due to the railway and the unregulated Sava prevented the development of the city in the north-south direction, so it developed longitudinally. The regulation of the Sava began in 1899, and by 1918 the river was consolidated into a single riverbed, its branches were cut off, and it was set into a characteristic bend with a centreline perpendicular to the medieval city core. However, the threat of flooding continued until the 1930s, when the Trnje embankment was completed, providing at least some protection for the southern border of the southern periphery.An urban population boom, characteristic of cities across the globe after World War I, took place in Zagreb. Most of the growth was due to people moving in from Zagreb’s rural surroundings and northern Croatia. One of the first problems that were detected was the lack of housing, especially that which would be affordable to the newly arrived immigrants. Although many of them found employment in the city or the factories that had by then developed on its periphery, their limited and modest incomes soon drove them out of the city centre and towards the periphery. There they built houses and had space for gardens and domestic animals, mostly on rented lots. The most pronounced characteristic of the population of the southern periphery was illegal construction; between 5,000 and 6,000 such buildings were erected in the interwar period. This phenomenon naturally led the new citizens into conflict with the city government.Even though Marxist historiography accused the ‘bourgeois government’ of deliberately ignoring the population of the periphery, this seems to be an exaggerated interpretation, though these citizens were often treated as ‘little people’. Various city governments, especially in the 1930s, had a pronounced social dimension, especially in regard to basic social benefits, but also in the construction of a limited number of dwellings for the poorer strata of the population. It seems more accurate to say that the city authorities ignored the southern periphery area. The city government lacked the funds to properly deal with the less-than-ideal area that was literally cut off from the city due to the railway and also exposed to flooding, which reinforced the mutual feeling of isolation.In this entire period, the population of the southern periphery was addressed as ‘little people’ and they never reached the level of ‘citizens’, marking this area a sort of ‘non-city’. In this sense, it is no wonder that, after the flood of 1923, only around 75 Zagreb citizens donated (mostly useless) clothing and footwear to victims from the periphery. Their relationship was problematic and full of mutual accusations. However, these ‘non-citizens’ and ‘little people’ actually forced the city government to begin addressing the southern periphery. Positive changes can be detected from the 1930s, during the mandate of Ivo Krbek. Following the mass immigration after World War I and until 1928, the inhabitants of the southern periphery reached a critical mass, i.e. they had sufficient numbers to allow them to remain in this area. The ideal plan of the city government was to buy houses from illegal builders or to offer them land in the regulated parts of the city, and thus free up this space for some future urban development. However, the chronic lack of funds and lots as well as the inadequate utility infrastructure hindered these efforts and widened the gap between ‘city’ and ‘periphery’.
U ovom je radu predstavljena metoda upravljanja pogonom dva sinhrona motora s paralelno povezanim trajnim magnetom, napajana jednim pretvaračem. Ovdje primijenjeni matrični konverter omogućuje ac-ac ...konverziju u jednom stupnju. Model matričnog konvertera i d-q model dvostrukih PMSMs izvode se u Matlab/Simulink-u. U industrijskim primjenama s dvostrukim motorima napajanim iz jedinstvenog pretvarača, smanjuje se volumen i težina pogonskog sustava, reduciraju se energetsko elektronički prekidači i druge komponente i smanjuju instalacijski troškovi. Zbog ovih su prednosti razvijene mnoge metode za upravljanje dvostrukim motornim pogonom. U ovom se istraživanju upravljanje motorom izvodi primjenom metode prosječne brzine. Upravljanje sinhronim motorima s dvostrukim permanentnim magnetom s jednim pretvaračem provodi se s neuronskim fuzzy regulatorima na bazi ANFIS-a. Svi se parametri motora smatraju jednakima budući da se razmatraju dva identična sinhrona motora s permanentnim magnetima. U simulaciji se istražuju dva različita uvjeta rada. U prvom slučaju, jedan od identičnih motora radi bez opterećenja, a drugi s nazivnim opterećenjem. U drugom slučaju, svaki motor radi s različitim momentima opterećenja koji variraju s vremenom. Prikazani su odgovarajući rezultati simulacije kako bi se pokazala učinkovitost pogonskog sustava.
Istraživački radovi o sustavima obnovljivih izvora energije za elektrifikaciju sela vrlo su intenzivni posljednjih godina. U udaljenim područjima neka su sela još uvijek izvan dosega električne ...energije jer je nemoguće povezivanje mrežnog sustava. U svijetu oko dvadeset posto svjetske populacije živi bez struje. Za poboljšanje ruralnog življenja, uporaba zelenih izvora energije obuhvaća veću mogućnost zapošljavanja, energetsku sigurnost i smanjenje učinaka staklenika. Konvencionalna metoda lokalne proizvodnje koristi dizel generator koji nije prihvatljiv za okoliš. Biogoriva su optimistični izbor za ispunjavanje ovog zahtjeva. Biodizel je obnovljivi izvor koji ima gotovo jednaku učinkovitost kao i konvencionalni petrodizel. Ovaj rad pokusno istražuje mješavine biodizela (dizel + biodizel) dobivene od nejestivih ulja kao alternativni izvor energije za pogon dizelskog generatora. U ovoj studiji se uzima u obzir sedam metilnih estera ekstrahiranih iz nejestivih ulja pongamije (indijske breze), jatrobe (jatrophe), mahuae, mesua ferrae (nageškara), sjemenki lana, neema (nim drveta) i sjemenki pamuka. Performanse generatora kao što su regulacija napona, frekvencija, potrošnja goriva, učinkovitost i emisijske značajke nalaze se u različitim uvjetima opterećenja. Na temelju opažanja, nađeno je da je ulje pongamije dobro alternativno gorivo za proizvodnju električne energije.
