Crowdbreaks: Tracking Health Trends using Public Social Media Data and Crowdsourcing

In the past decade, tracking health trends using social media data has shown great promise, due to a powerful combination of massive adoption of social media around the world, and increasingly potent hardware and software that enables us to work with these new big data streams. At the same time, many challenging problems have been identified. First, there is often a mismatch between how rapidly online data can change, and how rapidly algorithms are updated, which means that there is limited reusability for algorithms trained on past data as their performance decreases over time. Second, much of the work is focusing on specific issues during a specific past period in time, even though public health institutions would need flexible tools to assess multiple evolving situations in real time. Third, most tools providing such capabilities are proprietary systems with little algorithmic or data transparency, and thus little buy-in from the global public health and research community. Here, we introduce Crowdbreaks, an open platform which allows tracking of health trends by making use of continuous crowdsourced labelling of public social media content. The system is built in a way which automatizes the typical workflow from data collection, filtering, labelling and training of machine learning classifiers and therefore can greatly accelerate the research process in the public health domain. This work introduces the technical aspects of the platform and explores its future use cases

Analysis of EEC Regulation 2092/91 in relation to other national and international organic standards

This Deliverable 3.2 report presents an analysis of differences between EEC Regulation 2092/91 and other organic standards and their implementation, using a specially developed database (www.organicrules.org). It further reports on database development. The work was carried out as part of the “EEC 2092/91 (Organic) Revision” STREP project (No. SSPE-CT- 2004-502397) within the EU 6th Framework Programme. The main objective was to identify differences in organic standards in relation to Regulation (EEC) 2092/91 and to analyse selected national governmental and private organic standards with the aim of identifying specific areas in the (EEC) 2092/91 where revision in terms of harmonisation, regionalisation or simplification may be possible

Latent Dirichlet Allocation (LDA) for improving the topic modeling of the official bulletin of the spanish state (BOE)

Since Internet was born most people can access fully free to a lot sources of information. Every day a lot of web pages are created and new content is uploaded and shared. Never in the history the humans has been more informed but also uninformed due the huge amount of information that can be access. When we are looking for something in any search engine the results are too many for reading and filtering one by one. Recommended Systems (RS) was created to help us to discriminate and filter these information according to ours preferences. This contribution analyses the RS of the official agency of publications in Spain (BOE), which is known as "Mi BOE'. The way this RS works was analysed, and all the meta-data of the published documents were analysed in order to know the coverage of the system. The results of our analysis show that more than 89% of the documents cannot be recommended, because they are not well described at the documentary level, some of their key meta-data are empty. So, this contribution proposes a method to label documents automatically based on Latent Dirichlet Allocation (LDA). The results are that using this approach the system could recommend (at a theoretical point of view) more than twice of documents that it now does, 11% vs 23% after applied this approach

Do Consumers Want More Nutritional and Health Information on Wine Labels? Insights from the EU and USA

The global strategy to reduce the harmful use of alcohol launched in 2010 by the World Health Organization includes, amongst several areas of recommended actions, providing consumer information about, and labelling, alcoholic beverages to indicate alcohol-related harm. Labelling requirements worldwide for alcoholic drinks are currently quite diverse and somewhat limited compared to labelling on food products and on tobacco. In this context, the current paper contributes to the academic and political debate on the inclusion of nutritional and health information on wine labelling, providing some insights into consumer interest in, and preferences for, such information in four core wine-producing and -consuming countries: Italy, France, Spain, and the United States of America. A rating-based conjoint analysis was performed in order to ascertain consumer preferences for different formats of additional information on wine labels, and a segmentation of the sample was performed to determine the existence of homogeneous groups of consumers in relation to the degrees of usefulness attached to the nutritional and health information on wine labels. Our results highlight the interest expressed by European and United States consumers for introducing nutrition and health information on wine labels. However, the results of conjoint analysis show some signi\ufb01cant differences among stated preferences of the information delivery modes in different countries. In addition, segmentation analysis reveal the existence of signi\ufb01cant differences between consumer groups with respect to their interest in receiving additional information on wine labels. These differences are not only linked to the geographic origin of the consumers, or to socio-demographic variables, but are also related to wine consumption habits, attitudes towards nutritional information, and the degree of involvement with wine. This heterogeneity of consumer preferences indicates a need for a careful consideration of wine labelling regulations and merits further investigation in order to identify labelling guidelines in terms of the message content and presentation method to be used

Users' trust in information resources in the Web environment: a status report

This study has three aims; to provide an overview of the ways in which trust is either assessed or asserted in relation to the use and provision of resources in the Web environment for research and learning; to assess what solutions might be worth further investigation and whether establishing ways to assert trust in academic information resources could assist the development of information literacy; to help increase understanding of how perceptions of trust influence the behaviour of information users

New Tasks in Old Jobs: Drivers of Change and Implications for Job Quality

This overview report summarises the findings of 20 case studies looking at recent changes in the task content of five manufacturing occupations (car assemblers, meat processing workers, hand-packers, chemical products plant and machine operators and inspection engineers) as a result of factors such as digital transformations, globalisation and offshoring, increasing demand for high quality standards and sustainability. It also discusses some implications in terms of job quality and working life. The study reveals that the importance of physical tasks in manufacturing is generally declining due to automation; that more intensive use of digitally controlled equipment, together with increasing importance of quality standards, involve instead a growing amount of intellectual tasks for manual industrial workers; and that the amount of routine task content is still high in the four manual occupations studied. Overall, the report highlights how qualitative contextual information can complement existing quantitative data, offering a richer understanding of changes in the content and nature of jobs

Characterisation framework of key policy, regulatory and governance dynamics and impacts upon European food value chains: Fairer trading practices, food integrity, and sustainability collaborations. : VALUMICS project “Understanding Food Value Chains and Network Dynamics” funded by EU Horizon 2020 G.A. No 727243. Deliverable D3.3

The report provides a framework that categorises the different European Union (EU) policies, laws and governance actions identified as impacting upon food value chains in the defined areas of: fairer trading practices, food integrity (food safety and authenticity), and sustainability collaborations along food value chains. A four-stage framework is presented and illustrated with examples. The evidence shows that European Union policy activity impacting upon food value chain dynamics is increasing, both in terms of the impacts of policies upon the chains, and, in terms of addressing some of the more contentious outcomes of these dynamics. A number of policy priorities are at play in addressing the outcomes of food value chain dynamics. unevenness of the distribution of profit within food value chains, notably to farmers. Regulation of food safety and aspects of authenticity has been a key focus for two decades to ensure a functioning single market while ensuring consumer health and wellbeing. A food chain length perspective has been attempted, notably through regulations such as the General Food Law, and the rationalisation of the Official Controls on food and feed safety. However, there are still gaps in the effective monitoring and transparency of food safety and of food integrity along value chains, as exemplified by misleading claims and criminal fraud. This has led to renewed policy actions over food fraud, in particular. EU regulations, policies and related governance initiatives provide an important framework for national-level actions for EU member states and for EEA members. The more tightly EU-regulated areas, such as food safety, see fewer extra initiatives, but where there is a more general strategic policy and governance push, such as food waste reduction or food fraud, there is greater independent state-level activity. Likewise, there is much more variation in the application of both national and European (Competition) law to govern unfair trading practices impacting upon food value chains. This report presents the findings of a survey of members from the VALUMICS stakeholder platform, that were policy facing food value chain stakeholders across selected European countries, including both EU and EEA Member States. The survey was conducted to check the significance of the main policies identified in the mapping exercise at EU and national levels and so to incorporate the views of stakeholders in the research. The responses suggest the policy concerns identified in EU and national-level research resonate with food value chain stakeholders in participating nations. The report concludes by exploring in more detail how the themes of fairness and of transparency are being handled in the policy activities presented. Highlighted are the ways that both fairness and transparency can be extended within the existing frameworks of EU policy activity. The findings in this report provide an important context for further and detailed research analysis of the workings and dynamics of European food value chains under the VALUMICS project

A generic framework for the development of standardised learning objects within the discipline of construction management

E-learning has occurred in the academic world in different forms since the early 1990s. Its use varies from interactive multimedia tools and simulation environments to static resources within learning management systems. E-learning tools and environments are no longer criticised for their lack of use in higher education in general and within the construction domain in particular. The main criticism, however, is that of reinventing the wheel in order to create new learning environments that cater for different educational needs. Therefore, sharing educational content has become the focus of current research, taking e-learning into a whole new era of developments. This era is enabled by the emergence of new technologies (online and wireless) and the development of educational standards, such as SCORM (Sharable Content Object Reference Model) and LOM (Learning Object Metadata) for example. Accordingly, the broad definition of the construction domain and the interlocking nature of subjects taught within this domain, makes the concept of sharing content most appealing. This paper proposes a framework developed to describe the various steps required in order to enable the application of e-learning metadata standards and ontology for sharable learning objects to serve the construction discipline. The paper further describes the application of the proposed framework to a case study for developing an online environment for learning objects that are standardised, sharable, transparent and that cater for the needs of learners, educators and curricula developers in Construction Management. Based on the framework, a learning objects repository is developed incorporating educational and web standards. The repository manages objects as well as metadata using ontology and offers a set of services such as storing, retrieving and searching of learning objects using Semantic Web technologies. Thus, it increases the reusability, sharability and interoperability of learning objects

Safety of medication use in primary care

© 2014 Royal Pharmaceutical Society.BACKGROUND: Medication errors are one of the leading causes of harmin health care. Review and analysis of errors have often emphasized their preventable nature and potential for reoccurrence. Of the few error studies conducted in primary care to date, most have focused on evaluating individual parts of the medicines management system. Studying individual parts of the system does not provide a complete perspective and may further weaken the evidence and undermine interventions.AIM AND OBJECTIVES: The aim of this review is to estimate the scale of medication errors as a problem across the medicines management system in primary care. Objectives were: To review studies addressing the rates of medication errors, and To identify studies on interventions to prevent medication errors in primary care.METHODS: A systematic search of the literature was performed in PubMed (MEDLINE), International Pharmaceutical Abstracts (IPA), Embase, PsycINFO, PASCAL, Science Direct, Scopus, Web of Knowledge, and CINAHL PLUS from 1999 to November, 2012. Bibliographies of relevant publications were searched for additional studies.KEY FINDINGS: Thirty-three studies estimating the incidence of medication errors and thirty-six studies evaluating the impact of error-prevention interventions in primary care were reviewed. This review demonstrated that medication errors are common, with error rates between 90%, depending on the part of the system studied, and the definitions and methods used. The prescribing stage is the most susceptible, and that the elderly (over 65 years), and children (under 18 years) are more likely to experience significant errors. Individual interventions demonstrated marginal improvements in medication safety when implemented on their own.CONCLUSION: Targeting the more susceptible population groups and the most dangerous aspects of the system may be a more effective approach to error management and prevention. Co-implementation of existing interventions at points within the system may offer time- and cost-effective options to improving medication safety in primary care.Peer reviewe

Reading before buying - exploring consumer attitudes toward informative function of packaging

Oftentimes, packaging is the first and only marketing tool consumers encounter before a purchase, therefore it is considered to be the most important communication and informative tool (Behaegel, 1991; Peters, 1994). The aim of the research is to better understand food label usage of consumers. To make the identification of behaviour patterns possible and to understand the way consumers use labels on packaging netnography has been chosen as the research method. We identified market factors in our research which result in label use. Based on our results, two large consumer segments were identified: conscious and non-conscious consumer behaviours. Reading information on packaging can be classified in two ways, according to method of use (superficial, conditional, incidental) and place (home, or point of sale)
