Personalo mokymas(is) valstybinėse įmonėse / Personal education in government institutions

Vilkelionok, Liudmila 26 June 2014 (has links)
SANTRAUKA Personalo mokymas/is valstybinėje įmonėje Pagrindinė problema, kurią sudaro tyrimo „Personalo mokymas/is valstybinėje įmonėje“ pagrindą – besikeičiantis (tobulėjantis) gyvenimas ir tam nepasiruošusi visuomenė (valstybės įmonės „Visagino energija“ darbuotojai). Įsigilinama ir analizuojama – kodėl būtent žmonės, dirbantys valstybinėje įmonėje „Visagino energija“, nėra visapusiškai pasiruošę pasikeitimams, kurie reikalauja pastovaus mokymo/-si (tobulėjimo) – nors būtent šiuo metu valstybės įmonėje „Visagino energija“ vykdoma rekonstrukcija (tobulinamos technologijos, diegiamos naujos aptarnavimo įrangos). Tyrimo metu atlikta anoniminė apklausa, pateikiant įmonės „Visagino energija“ darbuotojams anketą. Išanalizavus tyrimo metu gautus duomenis, paaiškėjo rezultatai, kurie galėtų palengvinti, o gal ir išspręsti iškeltą problemą. Tyrimo metu buvo gaunami pakankamai teigiami rezultatai. Vienas iš svarbiausių gautų rezultatų – dauguma apklaustų įmonės darbuotojų turi teigiamą požiūrį į poreikį mokytis visą gyvenimą, taipogi mano, kad keistis yra būtina (mokytis, tobulėti). Apklausos metu išaiškėjo respondentų nuomonė, kad iniciatyva mokytis (tobulėti) turi būti skleidžiama pačių darbuotojų. Paraleliai buvo išanalizuotos priežastys, kodėl respondentai, norintys tobulinti savo kvalifikaciją, to nedaro. Tik trečdalis apklaustų darbuotojų įsitikinę, kad mokymai valstybės įmonėje „Visagino energija“ buvo organizuojami gerai. / SUMMERY Personnel Education in State Institution A basic problem being the study object of the thesis entitled Personnel Education in State Institution is our ever changing (improving) life and the unprepared community (the employees of the State Company VISAGINO ENERGIJA). In other words, here one gets insight into and examines why it is precisely the persons who are employed at the State Company VISAGINO ENERGIJA have not been comprehensively prepared for the changes that require a continuous training (improvement), meanwhile, it is precisely nowadays that a reconstruction (improvement of technologies and installation of new equipment) of the divisions at the State Company VISAGINO ENERGIJA is taking place. An anonymous quiz has been carried out during the study with the help of a questionnaire. After having analysed the obtained data, factors that might facilitate or perhaps even solve the raised problem are presented. Also, during the study one has obtained sufficiently positive results. One of the most important obtained results is that most questioned company's employees have a positive attitude to the need of training during one's whole life and also believe that it is indispensable to change (train and improve) themselves. During the quiz a respondents' opinion that an initiative for training (improving) must arise from employees themselves has become clear. In parallel, the reasons why some respondents are willing to improve their qualifications, but do not do so... [to full text]

Intensional infrastructure for collaborative mapping.

Mancilla, Blanca, Computer Science & Engineering, Faculty of Engineering, UNSW January 2004 (has links)
This thesis presents the Anita Conti Mapping Server, a Web interface and infrastructure for the creation and presentation of maps using an active, pervasive,multidimensional, global context. For each user, the context contains the parameterizations for every component of the system. In addition, parts of a user???s context may be shared with other users, so that the actions of one user directly affect the look, feel and content of another user???s system, thereby giving new meaning to the term collaborative computing. The mapping server consists of a Web interface, the GMT mapping tools, a database and the Omega typesetting system. Instead of the components being directly attached to each other through point-to-point communication, they are brought together by the context. This approach provides much more flexbility, since new components and new parameters can be more easily added to the overall system, with little or no change to the components already present. The whole infrastructure is built using intensional programming, a form of programming in which software entities are considered to be intensions (in the logical sense), i.e. mappings from contexts to ordinary entities, called extensions. The thesis presents a comprehensive overview of the development of intensional programming, and highlights its relevance for current work in the areas of electronic documents and distributed software configuration management. The mapping server is the most significant intensional application to date: it contains the most number of lines of intensional code ever written with the biggest context space implemented in a real, working system. The thesis focuses on the parameterization of the Web interface, the mapping engine and the generation of correctly typeset labels for maps to create a parameter space that accurately describes these components, and how this parameter space as a whole can be browsed by a user independently or as a member of a collaborative group. This thesis is just the beginning of a new way to look at mapping and proves that focusing on the context allows the creation of powerful extensible software.

The impact of strategic alignment on the performance of public organisations

Al Khalifa, Muneera Mohamed January 2016 (has links)
Today, technology is a key component in resolving a range of strategic issues; organisations are becoming increasingly dependent on Information Technology (IT) to improve their performance. In order to make the most out of the available technology, the continuing need to integrate IT strategies with business strategies remains evident. As illustrated from the extant literature, strategic planning and IT appear to present positive correlations with improved performance of organisations. Whilst there has been a range of research that has attempted to apply concepts such as strategic alignment, it remains that there are very few empirical findings centred on the overall effectiveness and usefulness of this approach. The aim of this study is to examine the impact of strategic alignment between business and IT on organisational performance of public organisations and depicts factors affecting this alignment. The development of the conceptual model, which guided this study, was based on prior research conducted in the field of strategic alignment, organisational performance, Information Systems (IS) success and IT acceptance. The rationale here is that previous research on strategic alignment has mainly focused on the development of models and frameworks and examines them in a suitable context or explores the relationships between the variables of the models. Research has shown the need for further investigation on the impact of strategic alignment on organisational performance. Hence, This study expands the knowledge in this field by examining the impact of the strategic alignment of business and IT on the performance of public organisations using quantitative method approach. Following to the development of the conceptual model, a web survey examines this relationship was sent to 413 executives of Bahrain public organisations. Data was collected using a web-based questionnaire from a sample of 163 participants, i.e. some of whom were IT executives, business executives or both. The results of this study imply a positive impact of strategic alignment on organisational performance of public organisations. It also suggest that IT acceptance and prior IS success significantly influence the strategic alignment in public organisations of Bahrain.

Website Success: An Integrated Theoretical Model

Schaupp, Ludwig Christian 04 May 2005 (has links)
As evidenced by the sheer number of websites presently on the Internet and the exorbitant amount of dollars that are spent on maintaining corporate websites determining the successfulness of these websites is of the utmost importance. In building a successful website the design must match the organization's objectives and these objectives need to be clearly defined. However, the objectives of a website differ depending upon the website type. As a result, from the user perspective, this results in varying ideas of satisfaction as well as success. Thus, from the user perspective determining success across websites is both goal and context specific. This dissertation investigated five variables which were believed to impact website satisfaction: information quality, system quality, perceived effectiveness, social influence, and trust. Theories in information systems success and information technology adoption provided theoretical foundations for this dissertation. The research was conducted by surveying multiple respondents, who were regular users of two different websites, each fitting into a different category within the taxonomy of websites. Structural equation modeling techniques were used to build the models of determinants of satisfaction for each website. The research results indicate that depending upon the type of website being evaluated different determinants of satisfaction were present. Four variables were found to be significant determinants of website satisfaction in the online community website: information quality, perceived effectiveness, social influence, and trust. However, in the information specific search website only three variables were found to significantly predict website satisfaction: information quality, system quality, and perceived effectiveness. Thus, this dissertation has shown that website users' determinants of satisfaction and overall successfulness is dependent upon the context of the website being evaluated and that determinants of satisfaction are goal specific. Several contributions were made by this study. In particular, this research is one of the first to empirically measure determinants of satisfaction, from the user perspective, in varying website contexts. / Ph. D.

An enterprise systems perspective to GRC IS implementation process

Spanaki, Konstantina January 2014 (has links)
Governance, Risk and Compliance (GRC) Information Systems (IS) as an integrated technology has been introduced recently to facilitate the demanding operational and financial environment of the enterprises. The implementation process and the adoption of such systems is considered as a significant parameter influencing the success of operational performance and financial governance and could support the competitive advantage practices within the organisations. However, GRC literature is limited regarding the analysis of the implementation and adoption success. Therefore, there is a need for further research and contribution about these systems and more specifically their implementation process. Consequently, this investigation and analysis can provide an insight of this process by examining the aspects of the implementation, the lifecycle phases followed and the enterprise value drivers in each of these phases. Therefore, a framework was developed for structuring the analysis of this implementation including all these three elements as these were provided by the theoretic background. The empirical context of this research includes three field investigation studies based on the experience of key implementation stakeholder groups as participants. These investigation studies were analysed using thematic techniques following an interpretative qualitative analysis approach. It was proved that organisations have, directly or indirectly, followed specific lifecycle phases when they implement GRC systems as these are also described in the framework. Also they should consider specific aspects about the GRC systems and enterprise value drivers for the different lifecycle phases but also for a holistic approach of the implementation process. Hence new GRC implementation projects can use the phases and the analysis of these elements to facilitate and ease their decision-making and strategic planning before launching the implementation project. The analysis of the GRC implementation proved that a strict GRC environment can be established in the organisations through the successful implementation of a GRC technology. The implementation process of such technologies would require a preparation for the organisational environment in order the implementation project to succeed the GRC goals and the system to be integrated and optimised harmoniously within the enterprise environment. This study provides insight of how this implementation projects could be planned and developed and gives a directive blueprint for preparing organisations hosting such technological initiatives. The results of all field investigation phases, which can be considered as the contributions to theory and practice of this research, can have twofold implications: initially the development of a theoretical framework based on enterprise systems theories, and also an analysis of the GRC implementation process in specific. The framework is designed to structure the analysis of the GRC implementation aspects, the lifecycle phases and the enterprise value drivers of the GRC implementation process. This framework is used for visualising and structuring a specific analysis of the GRC adoption and success, and therefore this analysis can be used by practitioners and researchers to further evaluate and analyse this process. Furthermore, organisations can use this analysis for decision-making processes; as this analysis can provide a primary view for the implementation projects.

A transition process from information systems acceptance to infusion behaviour in online brand communities : a socialization process perspective

Lim, Jaehoon January 2012 (has links)
Social media such as Facebook, Youtube, Twitter, and online communities plays an important role for knowledge production and diffusion as well as discussions among people. Among social media, online brand communities (OBCs) have recently received attention from both academics and practitioners due to the practical benefits of OBCs for consumers and companies. For consumers, knowledge sharing and its collective activities help them to make purchase decisions and to protect themselves against firms’ monopoly and oligopoly or collusion and anticompetitive actions. For companies, new ideas and feedback on brand products created by OBC members are useful input to develop new products and enhance existing product lines. Therefore, active content generation by community members is one of the critical success factors of OBCs. However, many scholars argue that only a few members who are more devoted to a community are tending to engage in OBC activities and many community members tend to remain in the periphery (sometimes called ‘lurkers') of the community by using OBCs merely for gathering information without any contributions. Therefore, it is important to make members in the periphery of the community transit to the core to increase members’ intentions and ‘devoted members’ to produce more valuable benefits for both consumers and firms. In spite of its importance, the literature is lacking in efforts to explain how and when community members in the periphery transit to the core of the community in a long-term perspective. This study aims to reveal how and why OBC members transit from the periphery to the core of the community and how to increase their intention to use OBC from a long-term perspective. OBC use behaviour is classified into, largely, two categories according to the purposes of an OBC: behaviour with a brand product consumption purpose; and behaviour with a social relationship building purpose. This study classifies OBC members as three clusters by social identity theory: tourists, minglers, and devoted members (devotees and insiders). The devoted members have valuable consumption knowledge of brand and strong social bonds in the OBC and the OBC members become a devoted member by accumulated brand knowledge and experiences through long-term OBC use. Therefore, from a socialisation aspect, this study adopts organisational socialisation theory as the theoretical lens to explain how and why the members evolve from novice members as tourist to devoted members in OBC contexts. Socialisation theories argue that there are usually three sequential stages for a member to gain full membership in a community: pre-entry, accommodation, and affiliation. In addition, this study adopts IS implementation theory to understand OBC user behaviours from an IS use behaviour perspective: acceptance in the pre-entry stage and routinisation in the accommodation stage and infusion in the affiliation stage. By reviewing socialisation theory and IS implementation theory, this study finds four significant motivations, those of information quality, trust, sense of belonging, and brand loyalty for intention of OBC use from the acceptance (pre-entry) to infusion (affiliation) stages. To integrate the socialisation perspective with the IS use perspective, this study adopts a technology acceptance model (TAM) as a theoretical framework to link to motivators in different OBC use behaviour from the acceptance to infusion stages. As a result, this study proposes a conceptual framework to explain the OBC members’ transition process from acceptance (pre-entry) to infusion (affiliation). The aim of this study is to predict and explain the transition of motivators for OBC use from pre-entry to affiliation and how to improve members’ intention of OBC use from a long-term perspective ultimately to foster ‘devoted members’. This study adopts an online survey targeting 518 participants who belong to 17 OBCs in South Korea and the conceptual framework is validated. The results show that all factors (i.e. information quality, trust, sense of belonging, brand loyalty) are significant determinants to increase intention to use OBCs and the factors have a causal relationship with each other to form a transition process from the acceptance (pre-entry) to infusion (affiliation) stages. This study also reveals that brand loyalty has a significant role to explain the transition process and directly influence user intention to use OBCs. The sense of belonging also directly affects members’ intention to use OBCs but has less impact than brand loyalty. In addition, the results indicate that TAM is an appropriate model to predict user behaviours in a long-term perspective to explain the change of OBC use behaviour from the acceptance to infusion stage and confirms that perceived usefulness and perceived ease of use have significant impact on the intention to use OBCs as in other IS studies. Understanding the transition process within OBCs has theoretical and practical implications. Theoretically, it will extend our understanding of how IS end users transit from acceptance behaviour to continued use and extended use of information systems in virtual community contexts. For managers, this study will provide them with insight on how to retain potential consumers in OBCs and facilitate their activities to gain consumer feedback on existing and new products.
