Techniques to measure sorption and migration between small molecules and packaging. A critical review
2015
The mass transfer parameters diffusion and sorption in food and packaging or between them are the key parameters for assessing a food product's shelf-life in reference to consumer safety. This has become of paramount importance owing to the legislations set by the regulated markets. The technical capabilities that can be exploited for analyzing product–package interactions have been growing rapidly. Different techniques categorized according to the state of the diffusant (gas or liquid) in contact with the packaging material are emphasized in this review. Depending on the diffusant and on the analytical question under review, the different ways to study sorption and/or migration are present…
Traditional Enterprise Business Intelligence Software Compared to Software as a Service Business Intelligence
2016
IntroductionBusiness Intelligence is a broad field of study. The major thrust of business intelligence theory analyzes certain factors to make highquality decisions. These factors include customers, competitors, business partners, economic environment and internal operations. Business Intelligence has the power to change the way people work, so that enterprises can compete more effectively and efficiently.A successful business intelligence solutions and successful implementation holds the key to the technological innovations together with the people, processes and culture of an organization to achieve a competitive and profitable BI strategy.Business Intelligence (BI) is the process of acqu…
Handling Evolving Data Warehouse Requirements
2015
A data warehouse is a dynamic environment and its business requirements tend to evolve over time, therefore, it is necessary not only to handle changes in data warehouse data, but also to adjust a data warehouse schema in accordance with changes in requirements. In this paper, we propose an approach to propagate modified data warehouse requirements in data warehouse schemata. The approach supports versions of data warehouse schemata and employs the requirements formalization metamodel and multiversion data warehouse metamodel to identify necessary changes in a data warehouse.
Evolution-Oriented User-Centric Data Warehouse
2011
Data warehouses tend to evolve, because of changes in data sources and business requirements of users. All these kinds of changes must be properly handled, therefore, data warehouse development is never-ending process. In this paper we propose the evolution-oriented user-centric data warehouse design, which on the one hand allows to manage data warehouse evolution automatically or semi-automatically, and on the other hand it provides users with the understandable, easy and transparent data analysis possibilities. The proposed approach supports versions of data warehouse schemata and data semantics.
Fuzzy subgroup mining for gene associations
2004
When studying the therapeutic efficacy of potential new drugs, it would be much more efficient to use predictors in order to assess their toxicity before going into clinical trials. One promising line of research has focused on the discovery of sets of candidate gene profiles to be used as toxicity indicators in future drug development. In particular genomic microarrays may be used to analyze the causality relationship between the administration of the drugs and the so-called gene expression, a parameter typically used by biologists to measure its influence at gene level. This kind of experiments involves a high throughput analysis of noisy and particularly unreliable data, which makes the …
“Heaven and Hell on Earth” A critical discourse analysis of religious terms in Norwegian autobiographies describing personal experience of mental hea…
2013
This article explores the use of religious terms in six Norwegian autobiographies written between 1925 and 2005 by people who themselves have been patients in the mental health services. Through a critical discourse analysis, we discuss the functions of religious discourse in the texts and its position in contrast to the medical discourse predominant in today's mental health services. It was found that religious (predominantly Christian) terms were used to varying degrees in all autobiographies as a means to capture the immensity and inherent ambivalence characteristic of mental health problems. Despite the “medical turn” in professional mental health discourse, there is no clear evidence o…
From Mood to Meaning: The Changing Model of the User in Entertainment Research
2015
In recent years, entertainment theory has undergone a paradigmatic shift: The traditional conceptualization of entertainment as an exclusively pleasurable affective state has been significantly extended by recent two-factor models. These models have introduced a second dimension of entertainment that incorporates more complex nonhedonic experiences, such as the search for meaning or intrinsic need satisfaction. They have not only crucially altered the way communication scholars conceptualize the audience of media entertainment but also our discipline's view on the effects of entertaining media content. The present article discusses the implications of this changing model of the media user b…
MADE – A Groupware Application to Support Real-Time Activities of Distributed and Cooperating Communities
2003
Abstract. Distributed work has increased during the last few years. Employees travelling around in different countries still need access to information and must be reachable by their colleagues. A variety of mobile devices have been utilised for this purpose. However, often, when using multiple devices, the information is available to the appropriate device only. Transferring data between the devices is not always an intuitive or easy thing to do – not while conversing at least. This paper presents a groupware application to support real-time actions of distributed communities. The problem of separate devices is addressed by combining multiple tools, media, into a platform independent aggre…
Packing a Trunk
2003
We report on a project with a German car manufacturer. The task is to compute (approximate) solutions to a specific large-scale packing problem. Given a polyhedral model of a car trunk, the aim is to pack as many identical boxes of size 4 × 2 × 1 units as possible into the interior of the trunk. This measure is important for car manufacturers, because it is a standard in the European Union.
A Note on Symmetry in Job Contact Networks
2007
Since the seminal work of Granovetter (1995), the sociological literature highlighted the importance of social relationships, like friends, relatives and acquaintances, as sources of information on jobs in labor markets. Such importance is also confirmed by a number of empirical studies.3 More recently, economists have devoted considerable attention to this topic,4 so that the study of individual and aggregate economic outcomes produced by the presence of social relationships in labor markets is becoming a fruitful research area in economics.
