Uso delle informazioni, decision making e strategie pubbliche: stato dell'arte e nuove traiettorie / INFORMATION USE, DECISION MAKING AND PUBLIC STRATEGIES: PUSHING KNOWLEDGE FORWARD / Information use, decision making and public strategies: pushing knowledge forward.

NOTARNICOLA, ELISABETTA 01 April 2019 (has links)
La tesi affronta il tema dell’utilizzo delle informazioni in ambito pubblico sulla scia di quanto avviato dalle teorie di (bounded) rationality, e di diversi filoni di (public) management che si sono occupati nel tempo di indagare i meccanismi attraverso i quali le informazioni vengono identificate, selezionate e utilizzate nei processi decisionali. Attraverso l’analisi delle politiche sociali nei comuni italiani, la tesi si occupa di indagare tre specifiche situazioni: la presentazione delle strategie e politiche pubbliche; la costruzione di piani strategici; la risoluzione di situazioni critiche e di trade-off complessi. La tesi mostra che le informazioni sono usate per presentare le decisioni tramite meccanismi di razionalità ed altri legati alla creazione di consenso per l’innovazione dei contenuti, governance e contesto di riferimento delle politiche sociali. Nella pianificazione strategica le informazioni vengono spesso solamente raccolte oppure utilizzate in modo strumentale. Nel caso di situazioni complesse e caratterizzate da trade-off, le informazioni di accounting hanno sia una valenza manageriale che politica di costruzione del consenso e delle motivazioni ad agire. / The PhD thesis deals with the issue of information use in the public sector. Building on (bounded) rationality theories and (public) management studies focusing on mechanisms through which information is identified, gathered and used in decision making processes, the thesis analysed what happens in Italian Municipalities, in the field of social care policies. Three different situations are analysed: public presentation of social care policies; social care strategic plans; wicked problems resolutions and trade off discussion. The thesis shows that information is used to present public strategies through rationality or by building consensus towards innovation in contents, governance and context of social care policies. In the case of strategic plans, information is often only presented or used instrumentally. In the case of trade-offs and wicked situation information is used both in a managerial perspective and in a political fashion so to build consensus and motivation for action.

Information Demand and Use : Improving Information Flow within Small-scale Business Contexts

Lundqvist, Magnus January 2007 (has links)
<p>Whilst the amount of information readily available to workers in information- and knowledge intensive business- and industrial contexts only seem to increase with every day, those workers still have difficulties in finding relevant and needed information as well as storing, distributing, and aggregating such information. Yet, whilst there exist numerous technical, organisational, and practical approaches to remedy the situation, the problems seem to prevail.</p><p>This publication describes the first part of the author’s work on defining a methodology for improving the flow of work related information, with respect to the information demand of individuals and organisations. After a prefatory description of the perceived problems concerning information flow in modern organisations, a number of initial conjectures regarding information demand and use in small-scale business contexts are defined based on a literature study. With this as the starting point the author sets out to, through an empirical investigation performed in three different Swedish organisations during 2005, identify how individuals within organisations in general, and these three in particular, use information with respect to such organisational aspects as roles, tasks, and resources as well as spatio-temporal aspects. The results from the investigation are then used to validate the conjectures and to draw a number of conclusions on which both a definition of information demand, as well as the initial steps towards defining a methodology for information demand analysis, are based. Lastly, a short discussion of the applicability of the results in continued work is presented together with a description of such planned work.</p>

These programs are social networks in which the functions of production and consumption of scientific information are intrinsic. The research assumes that students of a program suffer intellectual influence, directly or indirectly, through interactions with their teachers, especially when there is a closer relationship, such as research groups, for example. Thus, we have as aim the analysis of quotes for teachers in the area of Information Science and characteristics of these productions, from dissertations of students of PPGCI / UFPB in the period 2009/2011. This is a documentary research, in which we use bibliometric techniques for data analysis, extracted from 34 dissertations, stored in the program´s site. There are 18 of line "Memory, Organization, Access and Use of Info" (Line 1) and 16 of the line "Ethics, Policy and Management Info" (Line 2). In three years (2009-2011) we find 195 references to 14 of the 18 faculty members of the current frame PPGCI / UFPB, eight and six of Line 1 and Line 2, respectively. Of the total, 98 are articles, 35 books, 11 book chapters, 17 theses, four dissertations, 23 in communication events, and 13 corresponding to the sum of research projects, reports research, summaries, and references that do not allow us to identify the medium used for communication. The transmission ratios, sharing and use of scientific information in the academic and more specifically in the context of PPGCI / UFPB were evident in references and quotes for teachers program, contained in dissertations analyzed. The intellectual influence faculty on the students was proven. / Os programas de pós-graduação brasileiros são responsáveis por mais de 90% da produção científica nacional.

Oliveira, Glicia Lany Couto de 25 March 2013 (has links)
Made available in DSpace on 2015-04-16T15:23:24Z (GMT). No. of bitstreams: 1 ArquivoTotal.pdf: 2954210 bytes, checksum: ef1b4fe8f0e6f0f1a375e83510e7a8ac (MD5) Previous issue date: 2013-03-25 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / The use of information is an indispensable practice to any individual and as such, it is also essential to the professionals of education, especially teachers. Hence the importance of the issue here exposed being made clear by the fact of these professionals need of information for the development of their teaching practices. The present research on "Needs and use of information in the practice of science teachers" aims to analyze the needs and use of information of teachers from the urban area of the municipality of Santa Rita - PB. In that sense, the following question arises: What are the needs and use of information for science teachers in their teaching practices? An alternative approach of the Users´ Studies was used in this research, and the Sense-Making model was prioritized for offering through universal categories of cognitive metaphor, the situation (need for information), gap (cognitive emptiness), and use (informational help to bridge the cognitive emptiness), the logical way for meeting the research objectives. This is a descriptive field research, with a propositional nature. The population is consisted of 28 science teachers, distributed in schools in the urban areas of the municipality of Santa Rita. As an instrument of data collection, the mixed questionnaire was used. Data analysis, of qualitative and quantitative basis, shows that the study group is composed of qualified teachers who prioritize the post-graduation demonstrating interest in being updated for the practice of teaching. Although acknowledging the difficulties of the profession, most teachers manifest satisfaction and teach for pleasure in self-fulfillment. With emphasis on the categories of the Sense-Making, situation-gap-use, the situation reveals that teachers are constantly seeking to meet their information needs through the Internet, books, and educational videos, among others. In the gaps, barriers of time, language, terminology and quality of information were the most displayed, but they developed strategies that minimized the difficulties and could make use of the information. The use of information was centered on the development of teaching activities and the teachers were satisfied with it because it solved their informational problem. Actions to contribute to a better performance of the studied teachers about those questions in their teaching and pedagogical practices were proposed. We conclude that the development of the research contributed to the basis of the Science of Information, which is to provide information and impart knowledge to those who need it, making this the social responsibility in this area of knowledge, as well as in Education, when it makes itself responsible for the challenge of educating a society. Studying the teachers´ information needs and how they guide the search process and the use of information to satisfy their informational needs towards teaching practice, was assigned as a process of great value. / O uso da informação é uma prática indispensável a qualquer indivíduo e não poderia deixar deser aos profissionais da educação, sobretudo, os professores, logo, a importância da temáticaem questão evidencia-se pelo fato desses profissionais necessitarem, de informação para odesenvolvimento de suas práticas docentes.

Princípios para análise do uso de sistemas de informação / Principles for analyzing the use of information systems.

Arnaldo Alves Ferreira Júnior 07 April 2017 (has links)
Há anos, os estudos e avaliações de uso de produtos e/ou serviços disponibilizados em ambientes digitais ganharam importância, objetivando produtos e/ou serviços que ofereçam facilidade de uso e experiências agradáveis aos usuários destes. Ocorre, entretanto, que os usuários compreendem o mundo de maneira diferente e, consequentemente, suas necessidades de informação também são diferentes. Assim, partindo desta premissa, o principal objetivo desta pesquisa foi buscar a identificação e caracterização de princípios norteadores para análise do uso de sistemas de informação em ambientes digitais. A pesquisa foi conduzida com base nos estudos de redes de relacionamentos conceituais. Para tanto, utilizou-se uma infraestrutura (framework) conceitual e, partir das formas e comportamentos apresentados pelas conexões conceituais, foram observados e extraídos princípios para análise de uso dos sistemas informação. Trata-se, portanto, de uma pesquisa qualitativa, baseada no Método Bibliográfico e Levantamento (survey) em fóruns eletrônicos de discussão e, de modo complementar nas análises, foram utilizados métodos, técnicas e medidas dos estudos de redes, para identificação e caracterização dos princípios para avaliação de sistemas de informação. Como resultado, destaca-se que os princípios identificados representam elementos norteadores para a composição de parâmetros e criação de procedimentos que auxiliam na análise dos usos de sistemas de informação em geral. Não se trata de substituição dos métodos e técnicas amplamente utilizados nas áreas de Interface Humano Computador (IHC), Usabilidade, Análise de Sistemas e/ou Engenharia de Requisitos, contudo, os referidos princípios representam contribuições ao estudo das interações entre pessoas e sistemas de informação, considerando-se os relacionamentos entre os conceitos que estas pessoas ativam e/ou mobilizam para interpretar estes contextos de uso. / For years, studies and evaluations of the use of products and / or services made available in digital environments have gained importance, aiming products and / or services that offer ease of use and pleasant experiences to users of these. It occurs, however, that users understand the world differently and therefore their information needs are also different. Thus, based on this premise, the main objective of this research was to identify and characterize guiding principles for the analysis of the use of information systems in digital environments. The research was conducted based on the studies of networks of conceptual relationships. For that, a conceptual framework was used and, from the forms and behaviors presented by the conceptual connections, principles were observed and extracted for analysis of the use of information systems. It is therefore a qualitative research, based on the Bibliographic Method and Survey in electronic discussion forums and, in a complementary way in the analyzes, were used methods, techniques and measures of the networks studies, for identification and characterization of the Principles for evaluation of information systems. As a result, it is highlighted that the identified principles represent guiding elements for the composition of parameters and creation of procedures that help in the analysis of the uses of information systems in general. It is not a question of replacing the widely used methods and techniques in the areas of Computer Human Interface (IHC), Usability, Systems Analysis and / or Requirements Engineering, however, these principles represent contributions to the study of the interactions between people and information systems , Considering the relationships between the concepts that these people activate and / or mobilize to interpret these contexts of use.

Customer Information in New Service Development : Case Study in the Swedish Gaming Industry

Mulkova, Karolina, Meyer, Melanie January 2017 (has links)
The power of digital technology serves developers of new services as an access funnel to the vast amount of customer behavioural information. The utilization of this information is forecasted to differentiate the winners from the losers in the market and benefit the new service development process. This study explores the phenomenon of customer information in new service development empirically by looking at the industry at the forefront, the gaming industry. By conducting three case studies with leading Swedish game developers, it challenges the previous research assumptions that acquired and disseminated customer information is implicitly used. This study has made significant contributions by investigating the broader context of customer information use and differentiating among three types of use. The findings show that behavioural information is used to backup own decisions or to enhance the developers understanding, but is not directly applied to the decision task. Despite the great potential, this advanced type of customer information is only used in the post-launch stages of new service development, for service iterations. To further validate the findings and explore information use in new service development more in-depth, future research generating contextual detailed realtime data is needed.

The evolutionary ecology of animal information use and social dominance

Lee, Alexander January 2015 (has links)
Organisms are frequently faced with uncertainty regarding how best to exploit vital resources, and may benefit from collecting information about their distribution through space and time. However, the ways in which competition over resources might systematically facilitate or constrain an individual's ability to use information has been largely overlooked. In this thesis, I develop a conceptual framework for considering how the distribution of limited resources might underpin interdependencies between competition and information use. I focus on the evolutionary ecology of relationships between social dominance and social information use. I begin with an observational study of wild chacma baboons (Papio ursinus) suggesting that, when resources can be monopolised, individuals with low competitive ability are limited in their ability to use social information. Building on these findings, I then develop a general model exploring selection on social information use in a competitive context across three axes of 'resource ecology' (scarcity, depletion rate, monopolisability). This study makes predictions regarding the resource conditions under which competitive ability might constrain social information use, and the potential importance of social information use in the evolution of social dominance. I go on to test these predictions in chacma baboons using a field experiment. This experiment also explores whether the predictability of resource distribution might facilitate the decoupling of social information use from the competitive context in which it was collected. Taken together, these findings provide general insights into the combinations of ecological conditions and behavioural mechanisms that should underpin the benefits of social dominance. I end by building a simple population matrix model to study social dominance using an eco-evolutionary approach, in which feedback loops between ecological and evolutionary processes are considered. By modelling relationships between dominance rank and survival, reproduction, inheritance, and development, I am able to derive estimates of long-term fitness associated with dominance. Using these estimates, I generate predictions regarding how dominance hierarchies should impact the dynamics of group stability, viability, and fission.

Informed habitat choice in the heterogeneous world: ecological implications and evolutionary potential

Tolvanen, J. (Jere) 08 May 2018 (has links)
Abstract Animals live in a heterogeneous world where threats and abundance and quality of resources vary across space and time. Heterogeneity induces uncertainty in decisions that animals must make, e.g., where to breed. Adaptive decisions may be facilitated by personally collecting information on the quality of the environment and by observing the behaviour and success of other individuals. Such social information use is common in nature. I investigate information use in relation to ecological threats (brood parasites, nest predators) and long-term information use in breeding site choice in the wild. Moreover, I examine the genetic basis of social cue use in breeding site choice. I demonstrated experimentally that open-nesting hosts of a brood parasite, the common cuckoo (Cuculus canorus), can cue on cuckoo vocalizations to estimate cuckoo abundance and avoid breeding sites with high perceived parasitism risk. Another experiment showed that pied flycatchers (Ficedula hypoleuca) derive predation risk information from the fates of heterospecific nests, can associate the information with a nest site characteristic and generalize the association to own nest site choice. However, apparently only young females that made their choice quickly used the information in nest site choice. Pied flycatchers were further observed to collect habitat quality information based on the old nest contents during the post-breeding period. Use of the information in breeding site choice in the following spring varied between sex and age groups as well as geographically. Some birds integrated the post-breeding period information with the information available during settlement suggesting sequential social information use. Finally, quantitative genetic analyses revealed low additive genetic variances and genetic heritabilities of social cue use in breeding site choice in a collared flycatcher (Ficedula albicollis) population. These results demonstrate new aspects of informed habitat choice in wild animals which have important implications for species coexistence and community ecology, parasite-host coevolution, between-species niche dynamics and evolution. Between-individual variation in information use is highlighted throughout the thesis and warrants further research. The evolutionary potential of information use appears low, but more studies in other populations and species are needed. / Tiivistelmä Eläimet elävät ympäristössä, jossa resurssit ja uhat vaihtelevat ajallisesti ja alueellisesti. Tämä vaihtelu aiheuttaa epävarmuutta eläinten päätöksentekoon, kuten pesimäpaikan valintaan. Hyödyllisten päätösten tekoa voi edesauttaa keräämällä tietoa ympäristön laadusta itsenäisesti tai seuraamalla muiden yksilöiden käytöstä ja menestystä. Tällainen sosiaalisen informaation käyttö on yleistä eläinkunnassa. Tutkin informaation käyttöä ekologisten uhkien (pesäloiset, -pedot) suhteen ja pitkäaikaista informaation käyttöä pesimäpaikan valinnassa luonnonpopulaatioissa. Lisäksi selvitän pesimäpaikan valintaan liittyvän informaation käyton geneettistä periytyvyyttä. Selvitin kokeellisesti, että pesäloisen, käen (Cuculus canorus), isäntälajit voivat käyttää käkien ääntelyä vihjeenä alueellisesta loisintauhasta ja siten välttää korkean uhan alueita pesimäpaikan valinnassa. Toisessa kokeessa havaittiin kirjosieppojen (Ficedula hypoleuca) keräävän tietoa pesäpetouhasta toisen lajin pesätuhojen kautta, kykenevän yhdistämään tiedon erilliseen pesäpaikan ominaisuuteen ja käyttämään tätä assosiaatiota omassa pesäpaikan valinnassa. Kuitenkin vain nuoret naaraat, jotka tekivät valintansa nopeasti, käyttivät kyseistä informaatiota valinnassaan. Lisäksi havaitsin kirjosieppojen keräävän tietoa ympäristön laadusta pesinnän jälkeen vanhojen pesäsisältöjen avulla. Kyseisen tiedon käyttö pesimäpaikan valinnassa seuraavana keväänä vaihteli lintujen sukupuolen ja iän suhteen, kuin myös alueellisesti. Osa linnuista yhdisti pesimäpaikan valinnassaan aikaisempaa, pesinnän jälkeen kerättyä tietoa ja keväällä saatavilla olevaa sosiaalista informaatiota. Geneettinen analyysi viittasi pesimäpaikan valintaan liittyvän informaation käytön alhaiseen additiivisen geneettisen varianssin määrään ja siten alhaiseen geneettiseen periytyvyyteen sepelsiepolla (Ficedula albicollis). Väitöskirjani tulokset kuvaavat uudenlaisia informaation käytön muotoja eläinten pesimäpaikan valinnassa. Havainnot auttavat ymmärtämään pesälois-isäntä rinnakkaisevoluutiota, lajien välisiä vuorovaikutuksia, lajiyhteisöjen toimintaa ja evoluutiota. Yksilöiden välinen vaihtelu informaation käytössä näyttää olevan yleistä, ja lisätutkimuksen tarpeessa. Informaation käytön evolutiivinen potentiaali näyttää rajalliselta, mutta lisätutkimukset eri populaatioilla ja lajeilla ovat tarpeen.

Tailoring health communication:the perspective of information users' health information behaviour in relation to their physical health status

Enwald, H. (Heidi) 25 November 2013 (has links)
Abstract The aim of this thesis was twofold: firstly, to increase understanding about the user of health information; namely about differences of users´ characteristics of health information behaviour, and secondly, to contribute to the research on factors that could be used as bases to tailor health information. Health information behaviour was scrutinised as information needs and seeking and information use in particular. It was also studied in relation to individuals´ physical health status. More studies on information use are needed, because understanding individual characteristics in issues related to information use has been considered critical for promoting healthy behaviours. Moreover, the thesis addressed the gap in research on the relationship between health information behaviour and tailoring health information. The thesis consists of three empirical studies and a literature review. The empirical research environments were provided by an intervention study aiming to prevent type&#160;2 diabetes among a high risk population and by a population-based study among military conscription aged men. The setting was the City of Oulu in Northern Finland with the University of Oulu and the Oulu Deaconess Institute as the main operators of the studies. The empirical data were collected through questionnaires as well as through physiological and biochemical measurements during years 2010 and 2011. The data were analysed with statistical methods. Moreover, a literature review of tailored interventions studies using a computer as the medium of delivery in the context of physical activity, nutrition and weight management, was conducted. The findings indicate differences in health information users´ characteristics related to their information use as such and in relation to the indicators of their physical health status. It is suggested that, for example, health information presentation could be tailored on the basis of found differences and different message strategies and tactics could be used for different kinds of individuals. In addition, in the literature review the biases of tailored intervention studies stood out as influential on their outcomes. The thesis contributes to the current field of research on both health information behaviour and tailoring health communication. Moreover, the findings can support the development of more effective health promotion programs and intervention studies. / Tiivistelmä Väitöskirjatutkimukseni tavoitteena on lisätä ymmärrystä terveystiedon käyttäjistä ja erityisesti heidän terveysinformaatiokäyttäytymiseensä liittyvistä ominaisuuksista. Tutkimukseni tuottaa tietoa tekijöistä, joita voidaan käyttää terveystiedon räätälöinnin lähtökohtana. Terveysinformaatiokäyttäytymistä tarkastelen tiedontarpeiden ja -hankinnan sekä erityisesti tiedon käytön näkökulmasta. Informaatiokäyttäytymistä tutkitaan myös suhteessa tiedon käyttäjän fyysiseen terveydentilaan. Tutkimukseni vastaa tarpeeseen tutkia tiedon käyttäjiä, sillä tiedon käyttöön liittyvien yksilöllisten ominaisuuksien ymmärtäminen on keskeistä terveyden edistämisessä. Väitöskirja tuottaa uutta tietoa myös informaatiokäyttäytymisen ja terveystiedon räätälöinnin välisestä suhteesta. Väitöskirjani käsittää neljä osajulkaisua: kolme empiiristä tutkimusta ja kirjallisuuskatsauksen. Empiiriset tutkimukset toteutettiin tyypin&#160;2 diabeteksen ehkäisyyn tähtäävän interventiotutkimuksen (PreDiabEx) ja väestöpohjaisen tutkimuksen (MOPO) tarjoamissa tutkimusympäristöissä. Tutkimusten kohteina olivat miehet ja naiset, joiden riski sairastua tyypin&#160;2 diabetekseen oli korkea sekä kutsuntaikäiset miehet. Tutkimukset toteutettiin Oulussa ja päätoteuttajia olivat Oulun yliopisto ja Oulun Diakonissalaitos. Empiirinen aineisto kerättiin kyselyillä sekä fysiologisilla ja biokemiallisilla terveydentilaa ilmaisevilla mittareilla vuosien 2010 ja 2011 aikana. Aineisto analysoitiin tilastollisesti. Kirjallisuuskatsauksessa analysoidaan fyysisen aktiivisuuden, ravitsemuksen ja painonhallinnan interventiotutkimuksia, joissa tarkastellaan terveystiedon räätälöinnin vaikuttavuutta silloin, kun tiedonvälitykseen käytetään tietokonetta. Empiiristen tutkimusten tulokset viittaavat siihen, että niin terveystiedonkäyttäjien ominaisuuksissa informaatiokäyttäytymisessä kuin sen suhteessa heidän fyysisen terveydentilaansa on eroja. Terveystietoa tulisikin esittää eri tavoin erilaisille ihmisille, muun muassa erilaisia viestistrategioita ja -taktiikoita käyttäen. Kirjallisuuskatsauksen tulokset lisäsivät ymmärrystä siitä, miten tutkimusasetelman vinoumat voivat vaikuttaa interventiotutkimusten tuloksiin.

Organizational Social Capital and Performance Information Use: Analyzing the Link and Its Implications for Public Management

Tantardini, Michele 20 June 2016 (has links)
The use of performance information is the backbone of performance management. Performance information use refers to the willingness of public managers or other relevant stakeholders to incorporate quantitative or qualitative data in their decision-making. Both routine and nonroutine performance information is considered essential in managers’ decision making. Understanding the organizational factors that motivate public managers to use performance information is an important topic in the literature and practice of performance management. Although the number of studies on information use is growing, little is known about the impact of Organizational Social Capital (OSC). OSC is composed of the sub-dimensions of social interaction, trust, and shared goals. The main argument of this study is that OSC fosters performance information use in public administrations. It is expected that departments with high levels of organizational social capital are more likely to use both routine and nonroutine performance information. To test the hypothesized effect, department heads, middle managers, and other individuals with a supervisory role from 513 Florida County Government departments were surveyed. Furthermore, interviews, focus groups, and analysis of secondary data were performed to provide the context and the narrative surrounding the hypothesized effect. Analysis of the survey data reveals evidence in support of the hypothesized effects. Furthermore, the comparative case study analysis shows the existence of substantial differences in the history, background, organizational culture, and management between the two counties. The main findings show how reorganization processes as well as a lack of leadership may have detrimental effects to organizational social capital. Organizational social capital could be considered a relevant predictor of performance information use and thus deserves further attention from both researchers and practitioners.
