Activity Theory Based Ontology Model for Efficient Knowledge Sharing in eHealth  [PDF]
Yang Guo, Guohua Bai, Sara Eriksén
E-Health Telecommunication Systems and Networks (ETSN) , 2017, DOI: 10.4236/etsn.2017.62003
Abstract: Knowledge sharing has become an important issue that challenges the efficient healthcare delivery in eHealth system. It also rises as one of the most demanding applications with reference to dynamic interactivities among various healthcare actors (e.g. doctors, nurses, patients, relatives of patients). In this paper, we suggest an activity theory based ontology model to represent various healthcare actors. The goal of the suggested model is to enhance interactivities among these healthcare actors for conducting more efficient knowledge sharing, which helps to design eHealth system. To validate the feasibility of suggested ontology model, three typical use cases are further studied. A questionnaire based survey is carried out and the corresponding survey results are reported, together with the detailed discussions.
Health communication in primary health care -A case study of ICT development for health promotion
Mahmud Amina,Olander Ewy,Eriksén Sara,Haglund Bo JA
BMC Medical Informatics and Decision Making , 2013, DOI: 10.1186/1472-6947-13-17
Abstract: Background Developing Information and Communication Technology (ICT) supported health communication in PHC could contribute to increased health literacy and empowerment, which are foundations for enabling people to increase control over their health, as a way to reduce increasing lifestyle related ill health. However, to increase the likelihood of success of implementing ICT supported health communication, it is essential to conduct a detailed analysis of the setting and context prior to the intervention. The aim of this study was to gain a better understanding of health communication for health promotion in PHC with emphasis on the implications for a planned ICT supported interactive health channel. Methods A qualitative case study, with a multi-methods approach was applied. Field notes, document study and focus groups were used for data collection. Data was then analyzed using qualitative content analysis. Results Health communication is an integral part of health promotion practice in PHC in this case study. However, there was a lack of consensus among health professionals on what a health promotion approach was, causing discrepancy in approaches and practices of health communication. Two themes emerged from the data analysis: Communicating health and environment for health communication. The themes represented individual and organizational factors that affected health communication practice in PHC and thus need to be taken into consideration in the development of the planned health channel. Conclusions Health communication practiced in PHC is individual based, preventive and reactive in nature, as opposed to population based, promotive and proactive in line with a health promotion approach. The most significant challenge in developing an ICT supported health communication channel for health promotion identified in this study, is profiling a health promotion approach in PHC. Addressing health promotion values and principles in the design of ICT supported health communication channel could facilitate health communication for promoting health, i.e. ‘health promoting communication’.
Discharge planning: Narrated by nursing staff in primary healthcare and their concerns about using video conferencing in the planning session – An interview study
Malin Hofflander,Lina Nilsson,Sara Eriksén,Christel Borg
Journal of Nursing Education and Practice , 2013, DOI: 10.5430/jnep.v3n1p88
Abstract: Background/Objective: This paper sets out to describe experience-based reflections on discharge planning as narrated by nursing staff in primary healthcare, along with their concerns about how the introduction of video conferencing might influence the discharge planning situation. Methods: Interviews were conducted with nursing staff working at a primary healthcare centre in South East Sweden. Each interview took place was conducted on a one-to-one basis in dialogue form, using open questions and supported by an interview guide. It was then analysed using a phenomenological hermeneutic method. Participants were eligible for the study if they had given their informed consent and if they worked with discharge planning and home-based healthcare provision. In total, 10 of the 30 persons working at the primary healthcare centre participated in the study. Results: It was found that nursing staff in primary healthcare regarded the planning session as stressful, time-consuming and characterised by a lack of respect between nursing staff at the hospital and nursing staff in primary healthcare. They also described uncertainty and hesitation about using video conferences where patients might probably be the losers and nursing staff the winners. Conclusions: It is suggested that there is a need for improvement in communication and understanding between nursing staff at the hospital and nursing staff in primary healthcare in order to develop discharge planning. There is also a need for the nursing staff in primary healthcare to obtain more information about how Information Technology (IT) solutions could support their work and help them to find ways to collaborate.
Recent Advances in Chemical Modification of Peptide Nucleic Acids
Eriks Rozners
Journal of Nucleic Acids , 2012, DOI: 10.1155/2012/518162
Abstract: Peptide nucleic acid (PNA) has become an extremely powerful tool in chemistry and biology. Although PNA recognizes single-stranded nucleic acids with exceptionally high affinity and sequence selectivity, there is considerable ongoing effort to further improve properties of PNA for both fundamental science and practical applications. The present paper discusses selected recent studies that improve on cellular uptake and binding of PNA to double-stranded DNA and RNA. The focus is on chemical modifications of PNA's backbone and heterocyclic nucleobases. The paper selects representative recent studies and does not attempt to provide comprehensive coverage of the broad and vibrant field of PNA modification. 1. Introduction Peptide nucleic acid (PNA) is a DNA analogue that has the entire sugar-phosphodiester backbone replaced by a pseudopeptide linkage built of 2-aminoethylglycine residues (Figure 1) [1]. PNA is highly stable chemically and, because of the unnatural backbone, highly resistant to enzymatic degradation, which makes it an excellent candidate for in vivo applications as an oligonucleotide analogue. The neutral pseudopeptide backbone eliminates electrostatic repulsion (a factor that negatively affects oligonucleotide binding) and PNA binds to DNA and RNA with excellent affinity. PNA binds to double helical DNA via two competing binding modes, triple helix (PNA?:?DNA, 1?:?1), and strand invasion, where PNA displaces one of the DNA strands, typically followed by a triplex formation (PNA?:?DNA, 2?:?1) [1]. PNA also forms exceptionally strong and sequence-specific Watson-Crick duplexes with single-stranded DNA and RNA [2]. Interestingly, the sequence specificity of duplexes involving PNA is substantially higher than that of unmodified nucleic acids. Because of these superior qualities, PNA has become a powerful tool in chemical biology and biotechnology [3–5]. The main applications of PNA are as hybridization probes and molecular diagnostics of high affinity and selectivity for single-stranded DNA and RNA. PNA also holds a promise of becoming a novel gene therapy agent for targeting specific RNA molecules [3, 4]. Figure 1: Structures of DNA and PNA repeating units. Although PNA binds single-stranded DNA and RNA with superior affinity and selectivity, there are other properties of PNA that can be further improved. Most importantly, in vivo applications of unmodified PNA are hindered by poor cellular uptake and endosomal entrapment [6]. Current methods to enhance the cellular uptake of PNA, such as conjugation with cell penetrating peptides (CPP) [7,

Scientific Journal of Riga Technical University. Environmental and Climate Technologies , 2011, DOI: 10.2478/v10145-011-0031-1
Abstract: Ecotourism is able to contribute to biodiversity and to ensure the ecosystem function in Latvia through a complicated process of fulfilment of the established criteria for a valid ecotourism. The tourism flow in protected nature territories should be monitored, and the appropriate environmental management, education and a code of conduct need to be introduced. Ecotourism will serve for reducing the social and economic pressures on biodiversity and will promote responsible actions in support of environmentally friendly technologies and approaches. The areas selected for this study are the Natura 2000 territories that have undertaken the development of ecotourism facilities.

Eriks Aleksejevs, Janis Birzaks
Scientific Journal of Riga Technical University. Environmental and Climate Technologies , 2011, DOI: 10.2478/v10145-011-0022-2
Abstract: Changes in the ichthyofauna of Latvia's inland waters and their causes have been analyzed. Information about the distribution and occurrence of fish, obtained from various sources of literature, official reports, "BIOR" data bases on fishery statistics, as well as field research done from 1990 to 2010, has been collected and compared. Anthropogenic activity in the 20th century, such as rivers blocking by dams and fish introduction and acclimatization, has affected ichthyofauna more significantly.

Reflexiones morales sobre los animales en la filosofía de Martha Nussbaum
Martín Blanco,Sara;
Revista de Bioética y Derecho , 2012, DOI: 10.4321/S1886-58872012000200006
Abstract: the main question about moral treatment to non-human animals is not anymore a matter of applied ethics, assumed by some intellectuals, but a social demand which urges for its resolution. as a response to this requirement, martha nussbaum, offers -opposite to the proposals by peter singer, richars m. hare or tom regan- a new perspective to abord the speciesist problem: the capabilities approach. in this article we expose the main ideas in the nussbaum iniciative, and question, as a discussion, some aspects on her capacities focus.
Understanding poverty persistence in Spain
Sara Ayllón
SERIEs , 2013, DOI: 10.1007/s13209-012-0089-4
Abstract: The aim of this paper is to study the mechanisms behind poverty persistence in Spain. We examine the importance of past poverty experiences for explaining current poverty as opposed to observed and unobserved individual heterogeneity. Our results are based on the model proposed by Cappellari and Jenkins (J Appl Econometr 19:593–610, 2004a) that estimates poverty transitions while simultaneously controlling for attrition and initial conditions. We find that about 50% of aggregate state dependence is genuine: poverty in a given year increases in itself the chances of experiencing poverty again in the future. The remainder is explained, among other characteristics, by living with a head of household who has no educational qualifications, being an immigrant or cohabiting with teenagers. Our findings call for a comprehensive and coordinated strategy against poverty that should focus equally on income-support policies and on enhancing those characteristics that best protect against economic hardship. From a methodological point of view, we learn that unobservables affecting initial conditions and sample retention are exogenous to those related to poverty transience. However, results prove to be sensitive to the choice of poverty line.
