Sumažintos viešųjų pirkimų išlaidos, konkurencijos tarp tiekėjų padidėjimas, pagreitinti viešųjų pirkimų procesai, skatinimas naudoti įvairesnius pirkimų būdus, perkančiųjų organizacijų žmogiškųjų išteklių optimizavimas, pagerintos viešųjų pirkimų apskaitos ir kontrolės galimybės ir padidintas viešųjų pirkimų skaidrumas – tai pagrindiniai siekiniai, kuriuos užsibrėžė teisėkūros institucijos, inicijavusios viešųjų pirkimų perkėlimą į elektroninę erdvę. Tačiau ar iš tiesų teisėkūros organų siekiamybės atitinka realius rezultatus? Itin retai suteikiama galimybė tiesiogiai su viešaisiais pirkimais dirbantiems specialistams - praktikams pareikšti išankstines pastabas ar pasiūlymus, tokiu būdu užkertant kelią nenumatytų praktinių probleminių situacijų atsiradimui. Atsižvelgiant į tai ir buvo suformuluotas šio darbo tikslas - išanalizuoti viešųjų pirkimų vykdymo elektroninėmis priemonėmis teisinį ir praktinį reglamentavimą bei nustatyti, ar problemas, su kuriomis susiduria viešųjų pirkimų specialistai – praktikai, organizuodami viešuosius pirkimus elektroninėmis priemonėmis, galima išspręsti tik tikslinant (tobulinant) teisinį ir praktinį reglamentavimą. Darbe išanalizuotas esamas viešųjų pirkimų vykdymo elektroninėmis priemonėmis teisinis ir praktinis reglamentavimas, išskirti keturi elektroninių viešųjų pirkimų vykdymo etapai bei tyrimo metu, panaudojus interviu metodą ir apklausus viešųjų pirkimų srityje dirbančius praktikus, identifikuoti teisinio bei praktinio reglamentavimo...

But are these strivings of the legislative institutions meets the actual results? Very rarely opportunities to make preliminary comments or suggestions are given to specialists – practitioners working directly with public procurement, thus preventing unintended practical problem situations from occurring. Taking this into consideration was formulated the goal of this paper work – to analyze legal an practical regulation of the performance of public procurement by electronic means and to determine whether the problems faced by public procurement professionals – practitioners, organizing public procurement procedures by electronic means, can be solved only by revising (improving) the legal and practical regulation. Paper work analyze the existing legal and practical regulation of public procurement performance by electronic means, identifies four phases of public procurement performed by electronic means, and by interviewing public procurement practitioners using interview method identifies problematic factors of the legal and...

While modeling electronic service systems application quality parameters are always relevant. Future system must be reliable in operating, flexible enough in different situations and to have good efficiency. Price is important for system builder. Integrated quality parameter is defined for measuring and evaluation of all other quality parameters. In this work Petri nets architecture is picked as projecting methodology. electronic service information system - E-Government, is created and modeled theoretically. While studying information security methods in every projecting and modeling step we try to valuate these parameters: a) flexibility b) reliability c) performance d) price. While analyzing Petri nets it is required to make and describe information system theoretically. It is analyzed how to find the best way to reach optimal information security features. Application quality parameters are used for that.

In a time of rapid development of technologies, new forms of contracting online emerge. Two of these are analyzed in this thesis: click-wrap agreements (where an offer is accepted by way of clicking on an icon “I agree”) and browse-wrap agreements (where the offeree supposedly accepts the offer by browsing on a website, while the terms to the contract are accessible through an inconspicuous hyperlink). Click-wrap agreements are formed, they are accepted in a manner recognized as binding and the offeree knows the terms she assents to. Browse-wrap agreements are generally not formed. Even though the action of browsing on a website could indicate assent, the offeree must know that the act of browsing will be construed as acceptance. But the offeree is generally not made aware of the terms to the contract and thus cannot assent to what she is not aware of. However, if the offeree is in fact aware of the terms to the contract and still knowingly performs the action of browsing, a contract is formed and the offeree is bound. There are some doctrinal problems with an element of an offer – intent to be bound. E-contracting involves a great deal or recklessness by the offerors as well as offerees, leading to the conclusion that the action of clicking “I agree” does not really indicate the intent of the party who performs the act, to actually agree. There is no adequate answer to this problem presently. To sum up, the enforceability of click-wrap contracts is settled in courts, it is a...

Prie to turi prisitaikyti ir teisinė aplinka, todėl šiame magistro darbe yra aptariamos dvi sąlyginai naujos sutarčių sudarymo formos. Viena jų – spragtelėjimu sudaroma sutartis (angl. – click-wrap agreement). Čia oferentas akceptuoja sutarties sąlygas, paspausdamas monitoriaus ekrane ikoną „Sutinku“ ar pan. O situacija, kai sutartis turėtų būti sudaroma naršymu (angl. – browse-wrap agreement) – kiek sudėtingesnė, čia oferentas turėtų išreikšti savo sutikimą vien naršydamas internetinėje svetainėje, tačiau informacija, apie tai, jog naršymas bus laikomas sutikimu galima rasti spragtelėjus ant saito (angl. – hyperlink), kuris neretai būna pateikiamas puslapio apačioje, bet apie nuorodą su sutarties sąlygomis ir akceptavimo būdu oferentas nėra informuojamas, dažnai apie ją net nežino. Šiame darbe spragtelėjimu ir naršymu sudaromos sutartys analizuojamos kaip abstrakčios teisės koncepcijos, aptariamas jų pagrįstumas, tinkamumas. Lietuvos ir Jungtinių Amerikos Valstijų nacionalinės teisės sprendimai darbe aptariami lyginamuoju aspektu. Pirmiausia privalu išsiaiškinti ar galima sudaryti sandorius elektroninėmis (ne tik ryšio) priemonėmis. Nors elektroninėmis ryšio priemonėmis perduodama informacija prilyginama rašytiniams dokumentams (taigi, taip sudaromos sutartys tikrai galioja), spragtelėjimu ar naršymu sudaromų sutarčių atveju, ši teisinė...

Offering of electronic public services has become one of the principal parts of strategy of many governments all over the world. One of the 20 public services envisaged in program documents of the European Union is a service designated for citizens “Public libraries (availability of catalogues, search tools)”, that has to ensure open access to regional and global information resources. However taking into account the tasks that emerge when academic libraries start to create knowledge society it is very important to evaluate the spectrum of electronic public services provided exactly by academic libraries, possibilities of their quality and effectiveness improvement, and perspectives of their development.
