The present thesis examines questionnaire responses regarding optimal environmental attributes of public outdoor spaces for Chinese grandparents who are taking care of their grandchildren within selected urban residential communities in Shanghai, China. This thesis also assesses the needs of these grandparents providing childcare against the environmental attributes of urban public spaces. It uses the results to formulate design recommendations that will facilitate increased social interaction between grandparents with grandchildren and other persons in open public spaces of residential communities. Public spaces are often excellent locations for social interaction between grandparents with other persons within communities. Recently, there has been an increase in the number of Chinese grandparents providing childcare for their grandchildren, and many choose to spend time with grandchildren in these public open spaces. However, the needs and preferences of this demographic do not necessarily align with those of the general population. The current literature has identified five primary environmental attributes (access, comfort, opportunities of meeting, potential sensory elements, visibility) related to social interaction, each composed of a variety of landscape elements and characteristics. A framework was constructed based on these five environmental attributes and a variety of landscape elements and characteristics, and used to formulate a questionnaire for 46 grandparents, who take care of their grandchildren and live in high-rise buildings were surveyed. The selected participants were witnessed watching over their grandchildren in open spaces or the accompanying facilities and were asked to express a level of preference for a series of landscape elements presented in a questionnaire. The survey also included questions regarding demographic information. Descriptive and inferential analysis were then carried out through the survey data. The intended result of the study involved establishing a set of landscape architectural design recommendations that could be used in order to meet the preferences of this portion of society. Ideally, the findings will assist those involved in designing and managing outdoor environments in identifying the most salient environmental attributes for this growing sector of the Chinese community. The study could also help to prioritize interventions aimed at improving the use of open spaces and promoting social interaction among grandparents or grandparents with other neighbors. The approach also identified which landscape elements were most likely to attract grandparents to visit and stay in neighborhoods' open spaces longer with their grandchildren. Ideally, an outdoor public space designed following this set of design recommendations would contain the preferred environmental attributes and landscape elements of grandparents and their grandchildren and would provide more opportunities for social interaction. / Master of Landscape Architecture

No / The purpose of this paper is to utilize the existing theories and knowledge surrounding information systems (IS) evaluation and Green information technology (IT)/IS investments to develop a conceptual model for helping decision makers to overcome and reduce the impacts from Green IT/IS investment related to cost overruns or under-optimized budgets. The paper is discursive, based on the analysis and synthesis of literature pertaining to IS evaluation, Green IT/IS adoption and Sustainable/Green/CSR within an aviation context. Gaps in the preceding research have been identified, and a conceptual model is proposed. Additionally, further research and a methodology are suggested. The paper proposes a conceptual model that can identify factors including external factors derived from institutional theory, internal organizational factors, and a list of indirect costs associated with Green IT/IS investments for an aviation organization. As a conceptual paper, the study is limited to literature, identifying gaps, and proposing a model. The paper recommends further empirical validation of the proposed conceptual model. The conceptual model is helpful for decision makers within the aviation industry to enhance their understanding of the identification and management of indirect costs within the aviation context, which results in effective management of Green IT/IS indirect costs. The paper fills gaps in the knowledge of IS evaluation, Green IT/IS adoption/evaluation within aviation context through helping decision makers to understand, identify, and manage the associated indirect costs.

Syfte:Syftet med denna uppsats har varit att jämföra Aftonbladets nyhetsrapportering om IS i Sverige med den kunskap och de erfarenheter informanten besitter. Studien har även inkluderat ett genusperspektiv, detta för att reda ut hur vida kvinnor och män gestaltas olika i Aftonbladet. Metod:Det empiriska materialet i studien består av insamlad kvalitativ data genom en semikonstruerad intervju samt artiklar från Aftonbladet. Med framing som metod har ett ramverk skapats detta för att identifiera vad som står i de utvalda artiklarna samt för hur jag valt att gå tillväga i analysen av artiklarna. Slutsats:Resultatet av studien visar att Aftonbladet gestaltar IS och IS-krigare från Sverige negativt samt att informantens erfarenheter och kunskaper inom ämnet skiljer sig markant från hur tidningen beskriver det. Studien har också kommit fram till att kvinnor och män porträtteras olika i Aftonbladet när det handlar om IS i Sverige. / Purpose:The purpose of this study is to compare the news report from the swedish newspaper Aftonbladet about IS and IS-warriors with the knowledge and the experiences that the informant has. The study does also include a gender perspective, this to investigate how women and men frames differently. Method:The emperical material in this study comprises in gathering qualitative data existing of a semi constructed interview together with articles from Aftonbladet. I used the created framework as a method for analysing the articles. Conclusion:The result of the study show that Aftonbladet portrays IS and IS-warriors from Sweden in a negative way and also that the informants experiences and knowledge within the subject differ significantly from how the newspaper describes it. The study also shows that man and women are portrayed differently in Aftonbladet when the subject is IS in Sweden.

Masters's thesis deals with the assessment of driving school information system design and its changes.

Notre travail de recherche a consisté à examiner : comment l’E—Banking affecte la performance des agences commerciales ? Et quel rôle joue le SI bancaire, notamment le SI des processus commerciaux, par rapport à l’E-Banking ? Nous nous positionnons dans le courant de recherche de l’t-Évaluation en nous basant sur la théorie de ressources, l’appr0che processuelle et le modèle ISSM. 161 responsables d’agences, œuvrant dans dix banques tunisiennes, ont évalué les actifs, les valeurs (d’usage et d’échange) de leur Sl ainsi que les fonctionnalités de l’E Banking. Des outils de mesure ont été élaborés et validés : fonctionnalités E-banking, qualité des actifs SI (information, services et système informatique), valeurs du SI(usage : GRC et Marketing ventes ; échange avec : les clients, les fournisseurs et les partenaires). Notre approche processuelle en cinq étapes assure une bonne explication de nos construits latents : actifs SI, valeurs d’usage, valeurs d’échange, contribution du SI à la performance individuelle et organisationnelle).Notre modèle structurel explique 17% de la performance des agences avec un GoF de 46%.Les liens entre les fonctionnalités E—Banking et le SI bancaire soulèvent plusieurs dilemmes auxquels des recherches futures devraient pouvoir répondre. / Our research consists in examining: How does the E-Banking affects the performance of commercial agencies? And what role does the banking SI, including the SI business processes with respect to the E—Banking? We position ourselves in the field of research assessment based on the theory of resources, process- based approach and the ISSM model. 161 heads of agencies, working in ten Tunisian banks have valued the assets, values (usage and exchange) of their IT as well as the functionality of the E-banking. Measurement tools have been developed and validated: E—banking functionality, asset quality IS (information services and computer system), the values of IS (usage: GRC and Marketing & sales; exchange with: customers, suppliers and partners). Our five-step process approach provides a good explanation of our latent constructs: active IS usage values, exchange values, IS contribution to individual and organizational performance).Our structural model explains 17% of the performance of the agencies with GoF 46%. The links between the E-Banking features and bank IS raises several dilemmas for which future research should be able to respond.

The interest in studies with this naftoimidazole refers to synthetic possibilities for the imidazole ring of this molecule unsubstituted at positions 1,2 and 3, capable of undergoing nucleophilic substitution reactions with aliphatic and / or aromatic electrophiles. Furthermore, this which is the simplest naftoimidazole which can be obtained from ?-lapachone, has shown antitripanosomal activity, although not as significant as some aryl-substituted ?-lapachone derived naphthoimidazoles. This work reports the preparation of a series of compounds obtained by alkylation of BLI-H and the significant inhibitory activity on the growth of methicillin-resistant Staphylococcus aureus, Cryptococcus neoformans, Escherischia colii, Candida albicans, as well as Trypanosoma cruzi, achieved with these compounds. In addition to the products of alkylations, the search for derivatives with different substituents at carbon 2, led to the synthesis of two new ?-lapachone-derived naphthoimidazoles with acyl, amine and bromine groups respectively, in that carbon / N?cleos imidaz?licos est?o presentes nas estruturas de muitas subst?ncias com atividades farmacol?gicas, para diferentes finalidades.

Abstract Increasing information systems (IS) security breaches require investments in terms of IS security techniques/practices or personnel. Prior research on IS security investment has provided economic models based on neoclassical economics to assess how much to invest in IS security. These models assume that the goal of IS security investment is only benefit maximization, and that all of the actors involved are unbiased rational actors with complete information. It is argued in this thesis that these prior models for IS security investment are flawed for two reasons. First, benefit maximization is not an appropriate goal for IS security investment, because the benefits and costs of IS security investment cannot be reliably calculated. Second, decision makers are not unbiased rational actors, because they do not have enough information to make IS security investment decisions. To address these concerns, this thesis outlines a framework for IS security investment, which is based on behavioral economics. This framework makes new assumptions about IS security investment decision makers, and redefines the contextual nature of IS security investment. As an example of how to operationalize this framework in IS research, this thesis examines IS security investment decision-making by using a theoretical model drawn from reputational herding theory. A field study for empirical testing of the model was conducted, which involved surveying 88 information security experts in Finland. The results of the field study not only confirm the new framework, but also identify several motives that strongly predict IS security investment. In this thesis the assumptions proposed for the framework have also been also tested in a different research setting: the unauthorized uploading behavior of digital goods. This study involves 220 respondents, and the findings suggest that the proposed assumptions for the framework are also applicable in that new research setting. Overall, this doctoral thesis contributes to IS research by providing a framework to increase the overall understanding of how IS security managers make decisions with regard to IS security investment; moreover, this thesis presents empirically-grounded implications for how practitioners can improve the quality of their IS security investments. / Tiivistelmä Jatkuvasti lisääntyvät tietoturvaloukkaukset edellyttävät investointeja tietoturvatekniikoihin/käytänteisiin tai henkilöstöön. Aikaisempi tietoturvainvestointitutkimus on kehittänyt neoklassiseen taloustieteeseen perustuvia taloudellisia malleja tietoturvainvestointien määrän arvioimiseksi. Nämä mallit olettavat, että tietoturvainvestointien tavoitteena on ainoastaan hyötyjen maksimointi ja että kaikki toimijat ovat täydellisen tiedon pohjalta toimivia, puolueettomia ja rationaalisia. Tässä väitöskirjassa esitetään, että aikaisemmat tietoturvainvestointimallit ovat puutteellisia kahdesta syystä. Yhtäältä hyödyn maksimointi ei sovellu hyvin tietoturvainvestointien tavoitteeksi, koska sen hyötyjä ja kustannuksia ei voida luotettavasti laskea. Toisaalta päätöksentekijät eivät ole puolueettomia rationaalisia toimijoita, koska heillä ei ole käytettävissään tarpeeksi tietoa tietoturvainvestointipäätösten tekemiseksi. Nämä asiat huomioidaan tässä väitöskirjassa kehittämällä käyttäytymistaloustieteeseen perustuva tietoturvainvestointien viitekehys. Viitekehys esittää uusia olettamuksia tietoturvainvestointeja tekevistä päätöksentekijöistä ja tietoturvainvestointien kontekstuaalisesta luonteesta Väitöskirjassa havainnollistetaan kehitetyn viitekehyksen soveltamisesta tietojärjestelmätieteen tutkimuksessa tarkastelemalla tietoturvainvestointeihin liittyvää päätöksentekoa maineeseen perustuvan laumateorian (reputational herding theory) pohjalta laaditun teoreettisen mallin näkökulmasta. Kenttätutkimuksessa mallin testaamiseksi empiirisesti laadittiin kysely, johon vastasi 88 tietoturva-asiantuntijaa Suomessa. Kenttätutkimuksen tulokset sekä vastasivat uutta viitekehystä että toivat esiin useita tietoturvainvestointeja vahvasti ennustavia motiiveja. Väitöskirjassa kehitetyn viitekehyksen olettamuksia testattiin myös toisentyyppisessä tutkimusasetelmassa: digitaalisten hyödykkeiden luvaton lataaminen. Tähän tutkimukseen osallistui 220 vastaajaa, ja löydökset osoittavat esitettyjen olettamusten olevan hyödynnettävissä myös tässä uudessa tutkimusasetelmassa. Kaiken kaikkiaan tämän väitöskirjan kontribuutio tietojärjestelmätieteelle on sen tarjoama viitekehys, joka lisää ymmärrystä siitä, kuinka tietoturvapäälliköt tekevät tietoturvainvestointeihin liittyviä päätöksiä. Väitöskirja esittää myös empiiriseen tutkimukseen pohjautuvia käytännön implikaatioita tietoturvainvestointien laadun parantamiseksi.

International Telemetering Conference Proceedings / October 18-21, 2004 / Town & Country Resort, San Diego, California / A new class of precision timing and frequency reference is introduced that indirectly receives GPS timing and frequency information via TIA/EIA Standard IS-95 Code Division Multiple Access (CDMA) mobile telecommunications base station transmissions. Like cell phones, these products operate indoors without external antennas and provide accuracy, low cost and ease of installation. The technology fits particularly well in IP network synchronization and quality-of-service monitoring applications where rooftop antenna installation is often impossible. The salient characteristics of the IS-95 CDMA signals that make them suitable for this purpose and a general CDMA timing receiver architecture are described. Performance data versus similar references that use conventional GPS reception are also presented.

I denna undersökning har vi tittat på aktiva svenska nautiska befäls erfarenheter och åsikter om isnavigering i Östersjön. Vi har genom en kvantitativ undersökning försökt bilda oss en uppfattning om hur deras kompetensnivå är i denna speciella miljö, hur de anser attisvintrarna i Östersjön har påverkat deras arbete och om det finns ett behov av en vidareutbildning i isnavigering, samt i så fall vilka moment en sådan kurs skulle behövainnefatta. Vi har även undersökt om de anser att en renodlad isnavigeringskurs borde ingå idagens sjökaptensutbildning i Sverige. Undersökningen visar en varierande egenupplevd kompetens utifrån respondenternas erfarenhet av isvintrar. Undersökningen visar även att de som genomgått en kurs i isnavigering, oberoende av befattning och tidigare erfarenhet, anser sin kompetens vara tillräcklig. Behovet och viljan att genomgå en isnavigeringskurs är högt enligt respondenterna. Mer än hälften av de tillfrågade ville se en renodlad isnavigeringskurs redan under sjökaptensutbildningen. / The aim for this research has been to find out Swedish nautical officers’ thoughts of and their personal opinions on their competence when navigating in ice infested waters in the Baltic Sea. Through a quantitative research method we have tried to build us an understanding on how the nautical officer appreciates his or her competence in this very special environment, how they think that earlier ice winters have effected their duties at work as well as if there is a need for further training in ice navigation and which elements should be included in such training. We have also wanted to investigate active nautical officers’ opinion on including an ice navigation course, in full scale, at the Master Mariner Program in Sweden. The results show that nautical officers’ appreciation of their competence varies on the basis of their experience in years but also that attending a course in ice navigation gives officers, with little experience the appreciation of high competence in navigating ice infested waters. The will and need for a course in ice navigation, according to the results, is relatively high as well as the officers’ opinion on adding a ice navigation course to the curriculum at the Master Mariner Program in Sweden.
