Is There an Association between β-Carotene and Breast Cancer? A Systematic Review on Breast Cancer Risk
2020
It is suspected that diet influences the risk of developing breast cancer. Several β-carotenoids have been inversely associated with breast cancer risk, but association by type of tumor and participant characteristics remain nuclear. The objective of this review of epidemiological studies is to investigate the relationship between β-carotenoids and breast cancer. This review covers the 2014-2020 period and was carried out using the PubMed and EMBASE databases. Only epidemiological studies carried out on β-carotenoids and breast cancer were included. The initial keyword search yielded 1559 results and finally a total of 28 studies were included. The quality of the articles and the risk of bi…
Semantic retrieval: an approach to representing, searching and summarising text documents
2011
Nowadays, the internet is the major source of information for millions of people. There are many search tools available on the net but finding appropriate text information is still difficult. The retrieval efficiency of the presently used systems cannot be significantly improved: ‘bag of words’ interpretation causes losing semantics of texts. We applied the functional approach to represent English text documents. It allows taking into account semantic relations between words when indexing documents and use ordinary English sentences as queries to a search engine. The proposed retrieval mechanisms return only highly relevant documents. They make it possible to generate content-aware summarie…
Word search sequences in teacher-student interaction in an English as medium of instruction context
2019
This study explores the ways students in a higher education setting engage in word searches. The investigation draws on 30-hour video recordings of content classes in an English as a medium of instruction university in Turkey. Using conversation analysis, the study focuses on the interactionally accomplished functions of vocal and visual practices deployed by the students in the course of a word search. We revealed that word searches are constructed through publicly visible resources (i.e. gaze, body orientation, gestures) and explicit formulaic expressions (i.e. how can I say it?), and accomplished via bilingual resources. It was also observed that the teacher does not orient to word searc…
Classifying Economics for the Common Good: Connecting Sustainable Development Goals to JEL Codes
2020
How does economics research help in solving societal challenges? This brief note sheds additional light on this question by providing ways to connect Journal of Economic Literature (JEL) codes and Sustainable Development Goals (SDGs) of the United Nations. These simple linkages illustrate that the themes of SDGs have corresponding JEL classification codes. As the mappings presented here are necessarily imperfect and incomplete, there is plenty of room for improvements. In an ideal world, there would be a JEL classification system for SDGs, a separate JEL code for each of the 17 SDGs.
On the use and value of new media and how medical students assess their effectiveness in learning anatomy.
2004
The new media have become widely used tools in medical instruction today. But are they regarded as useful by students training to become medical doctors? What are students' most important criteria for a good CD-ROM or valuable Internet resources? To answer these questions, and to obtain definite data on the use of new media, we distributed a questionnaire to preclinical medical and dental students of the Johannes Gutenberg University in Mainz, Germany. The evaluation of 397 questionnaires demonstrates that 94.9% of the students use personal computers; 91.6% of the 85.8% who own a computer have access to the Internet. The Internet is used at least once a week by 70.1% of students for private…
Classifying economics for the common good : a note on the links between sustainable development goals and JEL codes
2021
Purpose This brief note sheds light on the links between Journal of Economic Literature (JEL) codes and the Sustainable Development Goals (SDGs) of the United Nations. Design/methodology/approach Three alternative methods based on keyword overlap to establish links between SDGs and JEL codes are presented. Findings These simple linkages illustrate that the themes of SDGs have corresponding closely related JEL classification codes. Research limitations/implications The mappings presented in this note are based on simple keyword overlap and are therefore necessarily imperfect and incomplete. There is plenty of room for further development. Practical implications Despite the demonstrated possi…
TB-Structure : Collective Intelligence for Exploratory Keyword Search
2017
In this paper we address an exploratory search challenge by presenting a new (structure-driven) collaborative filtering technique. The aim is to increase search effectiveness by predicting implicit seeker’s intents at an early stage of the search process. This is achieved by uncovering behavioral patterns within large datasets of preserved collective search experience. We apply a specific tree-based data structure called a TB (There-and-Back) structure for compact storage of search history in the form of merged query trails – sequences of queries approaching iteratively a seeker’s goal. The organization of TB-structures allows inferring new implicit trails for the prediction of a seeker’s i…
