Alcohol imagery on popularly viewed television
- in the UK. J Public Health 2014;36:426–34
"... A B S T R AC T Background Exposure to alcohol consumption and product imagery in films is associated with increased alcohol consumption among young people, but the extent to which exposure also occurs through television is not clear. We have measured the occurrence of alcohol imagery in prime-time ..."

-time broadcasting on UK free-to-air television channels. Methods Occurrence of alcohol imagery (actual use, implied use, brand appearances or other reference to alcohol) was measured in all broadcasting on the five most popular UK television stations between 6 and 10 p.m. during 3 weeks in 2010, by 1-min interval
The R*-tree: an efficient and robust access method for points and rectangles
- INTERNATIONAL CONFERENCE ON MANAGEMENT OF DATA
, 1990
"... The R-tree, one of the most popular access methods for rectangles, is based on the heuristic optimization of the area of the enclosing rectangle in each inner node. By running numerous experiments in a standardized testbed under highly varying data, queries and operations, we were able to design the ..."

From Few to many: Illumination cone models for face recognition under variable lighting and pose
- IEEE Transactions on Pattern Analysis and Machine Intelligence
, 2001
"... We present a generative appearance-based method for recognizing human faces under variation in lighting and viewpoint. Our method exploits the fact that the set of images of an object in fixed pose, but under all possible illumination conditions, is a convex cone in the space of images. Using a smal ..."

illumination cone (based on Euclidean distance within the image space). We test our face recognition method on 4050 images from the Yale Face Database B; these images contain 405 viewing conditions (9 poses ¢ 45 illumination conditions) for 10 individuals. The method performs almost without error, except
MATRIX FACTORIZATION TECHNIQUES FOR RECOMMENDER SYSTEMS
- IEEE COMPUTER
, 2009
"... As the Netflix Prize competition has demonstrated, matrix factorization models are superior to classic nearest-neighbor techniques for producing product recommendations, allowing the incorporation of additional information such as implicit feedback, temporal effects, and confidence levels. Modern co ..."

Amazon.com and Netflix have made recommender systems a salient part of their websites. Such systems are particularly useful for entertainment products such as movies, music, and TV shows. Many customers will view the same movie, and each customer is likely to view numerous different movies. Customers
The moral economy of inequality: popular views on income differentiation, poverty and wealth
"... This article asks how ordinary people in Germany perceive and legitimize economic disparities in an era of rising income inequality. Based on in-depth qualitative interviews with respondents from higher and lower social classes, the paper reconstructs the 'moral economy' that underlies po ..."

popular views of inequality. While respondents agree with abstract inegalitarian principles-i.e. income differentiation based on merit-they are concerned with specific instances of inequality, especially poverty and wealth. These are criticized because they are seen to imply intolerable deviations, both
Constrained K-means Clustering with Background Knowledge
- In ICML
, 2001
"... Clustering is traditionally viewed as an unsupervised method for data analysis. However, in some cases information about the problem domain is available in addition to the data instances themselves. In this paper, we demonstrate how the popular k-means clustering algorithm can be pro tably modi- ed ..."

Similarity estimation techniques from rounding algorithms
- In Proc. of 34th STOC
, 2002
"... A locality sensitive hashing scheme is a distribution on a family F of hash functions operating on a collection of objects, such that for two objects x, y, Prh∈F[h(x) = h(y)] = sim(x,y), where sim(x,y) ∈ [0, 1] is some similarity function defined on the collection of objects. Such a scheme leads ..."

We show that rounding algorithms for LPs and SDPs used in the context of approximation algorithms can be viewed as locality sensitive hashing schemes for several interesting collections of objects
I Tube, You Tube, Everybody Tubes: Analyzing the World’s Largest User Generated Content Video System

How should substance use problems be handled? Popular views in Sweden, Finland, and Canada

Abstract Purpose -Although the way in which, for example, substance use problems are conceived and reacted to (by experts and treatment professionals but also by the environment), can have vast consequences for those directly or indirectly concerned, there is little systematic knowledge about how various preferred approaches differ between types of problems and sociocultural settings. In an ambition to at least partly mend this gap, this paper aims to compare how the general public in Sweden, Finland, and Canada appraise four generically different approaches to dealing with substance use problems, as these are applied to problem use of alcohol, cannabis, heroin, and cigarettes. Design/methodology/approach -The paper uses data from three national surveys, aimed at uncovering how representative population samples from Sweden, Finland, and Canada perceive and understand the character of, and the proper way of handling, various addictive problems. Data from these surveys have been used to discern and operationalize four basic "models of helping and coping" as these have been outlined by
BGP Routing Stability of Popular Destinations
, 2002
"... The Border Gateway Protocol (BGP) plays a crucial role in the delivery of traffic in the Internet. Fluctuations in BGP routes cause degradation in user performance, increased processing load on routers, and changes in the distribution of traffic load over the network. Although earlier studies have r ..."

Our results suggest that operators can engineer their networks under the assumption that the BGP advertisements associated with most of the traffic are reasonably stable.
