The influence of albumin on the pasting and rheological properties of rice flour was investigated. Albumin was removed from the flour of three rice cultivars (Amaroo, Opus, and Langi) by water extraction and the pasting profile of the albumin‐depleted flour was analyzed using the Rapid ViscoAnalyser (RVA). Removal of albumin resulted in a significant (P < 0.5) decline in all the pasting parameters measured. When the extracted albumin was added to pure rice starch, exactly opposite trends occurred. The concentration of albumin in rice starch had a positive linear relationship with all pasting parameters measured. When the gels formed after RVA analyses were analyzed using the TA‐TX2 texture analyzer, the concentration of albumin had a positive linear relationship with hardness, but a near linear negative relationship with adhesiveness. The presence of albumin in rice starch slowed the uptake of water by starch in the initial stages of cooking, but the water uptake accelerated in later stages, and the final water absorption was higher in the samples containing albumin than in pure starch. The water‐soluble nature of albumin suggests that protein‐water‐starch interactions could be responsible for its effect on the physical properties of rice.
Abstract:This paper details the results of a Masters project investigating attitudes amongst decision-makers in the European Parliament to the role of information in their work, and their ability to identify, access and evaluate that information most relevant to their needs. The main aims of the research were to elicit data regarding levels of satisfaction amongst MEPs in relation to information retrieval, and to identify areas of information need which were not being addressed. The research methodology consisted of a postal survey of United Kingdom MEPs, achieving a 34% response rate. The results included: the wide range of subjects that are of interest to MEPs; that all MEPs have research assistants to help in their work, with an average of 3.5 assistants per MEP; the majority of these assistants are based in the UK and are employed full-time; and that the most popular sources were unofficial, informal contacts and MEPs own files, as opposed to the official European Union databases and services. The main problems faced by MEPs in information retrieval are pressure of time and the overwhelming number and variety of information sources available. Recommendations are made for further research into the information needs of MEPs and information management practices within the European Union.
This paper describes the results of an observational study of the information seeking behaviour of Members of Parliament. It is argued that political life functions on a flow of information and that information itself is a prime resource. The study sought to determine the characteristics that impact upon the manner in which information is sourced and used by parliamentarians. For this project a shadowing methodology was adopted. The conclusions drawn include that UK Members of Parliament are subject to a range of triggers of information seeking, in an information rich environment where the amount of information presents decision makers with difficulties. Public accountability results in demands from a wide variety of individuals, groups and associations. MPs are also expected to be knowledgeable about a wide variety of issues, while information need is frequently unpredictable and reactive. Members must be efficient information gatherers and managers and they must be flexible in their attitudes to information seeking, while retaining the capacity to critically appraise the quality of sources.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
