A staggering number of clinical trials fail to meet recruitment goals, which leads to delays, early trial termination, or inability to draw conclusions at trial completion due to loss of statistical power. There can be ethical implications when research participants are exposed to risk but the research does not result in gains in scientific knowledge even though some participants may have had personal benefit. Many potential explanations have been offered, including patient lack of awareness of clinical trials that may be of interest to them and recruitment methods that have not kept pace with advances in communications and other technologies. The Clinical Trials Transformation Initiative CTTIa public-private partnership whose mission is to increase the quality and efficiency of clinical trials, launched the Recruitment Project to identify and propose possible solutions to barriers in clinical trial recruitment.
Kentaro Toyama There are no technology shortcuts to good education. For primary and secondary schools that are underperforming or limited in resources, efforts to improve education should focus almost exclusively on better teachers and stronger administrations.
Information technology, if used at all, should be targeted for certain, specific uses or limited to well-funded schools whose fundamentals are not in question. But, the conclusions are relevant for a broad class of primary and secondary schools in developed countries, as well.
The history of electronic technologies in schools is fraught with failures. Computers are no exception, and rigorous studies show that it is incredibly difficult to have positive educational impact with computers. Technology at best only amplifies the pedagogical capacity of educational systems; it can make good schools better, but it makes bad schools worse.
Technology has a huge opportunity cost in the form of more effective non-technology interventions. Many good school systems excel without much technology. The inescapable conclusion is that significant investments in computers, mobile phones, and other electronic gadgets in education are neither necessary nor warranted for most school systems.
In particular, the attempt to use technology to fix underperforming classrooms or to replace non-existent ones is futile. And, for all but wealthy, well-run schools, one-to-one computer programs cannot be recommended in good conscience. All of the evidence stands on its own, but I will tie them together with a single theory that explains why technology is unable to substitute for good teaching: Quality primary and secondary education is a multi-year commitment whose single bottleneck is the sustained motivation of the student to climb an intellectual Everest.
Though children are naturally curious, they nevertheless require ongoing guidance and encouragement to persevere in the ascent. Caring supervision from human teachers, parents, and mentors is the only known way of generating motivation for the hours of a school day, to say nothing of eight to twelve school years.
While computers appear to engage students which is exactly their appealthe engagement swings between uselessly fleeting at best and addictively distractive at worst. No technology today or in the foreseeable future can provide the tailored attention, encouragement, inspiration, or even the occasional scolding for students that dedicated adults can, and thus, attempts to use technology as a stand-in for capable instruction are bound to fail.
With respect to sustaining directed motivation, even the much-maligned rote-focused drill-sergeant disciplinarian is superior to any electronic multimedia carnival.
The author retracts this statement and agrees with BonTempo, as his articles actually suggest that even this is not possible if neither teachers nor students are motivated to begin with. Subscribe now to follow this Educational Technology Debate via email updates sent to your inbox.

There are three reasons why I’m looking forward to next week’s July Sentiment Analysis Symposium in . Business and government should work more closely together to reduce inequality and foster inclusive growth.
To help achieve this, at the Paris Peace Forum, Gabriela Ramos, OECD Chief of Staff, G7/G20 Sherpa and leader of the OECD’s Inclusive Growth Initiative, and Emmanuel Faber, Chairman & CEO of Danone, launched the Business for Inclusive Growth (B4IG) Platform.
Document Level Sentiment analysis is performed for the whole document and then decide whether the document express positive or negative sentiment.
 Entity or Aspect Level sentiment analysis performs finer-grained analysis. The goal of entity or aspect level sentiment analysis is to find sentiment on entities and/or aspect of those entities. Sentiment analysis provides the capability to extract information and trends from textual data, giving an overview of the level of customers' satisfaction and it allows determining strategies to improve product quality (Prabowo & Thelwall, ).
