    MYANMAR MEDIA AND INFORMATION NEEDS SURVEY MYANMAR MEDIA AND INFORMATION NEEDS SURVEY Good morning/afternoon/evening. My name is __________. I am here on behalf of MSR, a Research Agency in Myanmar. I am here to learn about how people in this neighbourhood feel about some important social matters and current affairs and also to understand people’s media habits and needs. We would like to talk to you and other people in your neighbourhood about these matters. You were chosen randomly, and your help in answering our questions is important and voluntary. If you agree to take part, I will ask you questions about your media usage and your opinion about social and economic matters. The information will be used to improve radio/TV programmes. There are no right or wrong answers to these questions, I am only interested in your own view or experiences. We intend to use your responses for research purposes only. Your identity will be kept confidential and your responses will not be credited to you, which means we will remove anything that is likely to identify you as taking part in this study, such as names and villages. Your answers to my questions will be combined with answers from many other people, to avoid your responses being identified as yours. Although there is no direct benefit to you for participating, the answers that you provide may help to develop better radio/TV programmes for people in this and other communities in Myanmar. The combined information that we collect from people in Myanmar will be shared and used to improve social matters in your community.

  • A Comparison of Approaches to Advertising Measurement: Evidence from Big Field Experiments at Facebook∗
    A Comparison of Approaches to Advertising Measurement: Evidence from Big Field Experiments at Facebook∗ Brett R. Gordon Florian Zettelmeyer Kellogg School of Management Kellogg School of Management Northwestern University Northwestern University and NBER Neha Bhargava Dan Chapsky Facebook Facebook April 12, 2018 Abstract Measuring the causal effects of digital advertising remains challenging despite the availability of granular data. Unobservable factors make exposure endogenous, and advertising's effect on outcomes tends to be small. In principle, these concerns could be addressed using randomized controlled trials (RCTs). In practice, few online ad campaigns rely on RCTs, and instead use observational methods to estimate ad effects. We assess empirically whether the variation in data typically available in the advertising industry enables observational methods to recover the causal effects of online advertising. This analysis is of particular interest because of recent, large improvements in observational methods for causal inference (Imbens and Rubin 2015). Using data from 15 US advertising experiments at Facebook comprising 500 million user-experiment observations and 1.6 billion ad impressions, we contrast the experimental results to those ob- tained from multiple observational models. The observational methods often fail to produce the same effects as the randomized experiments, even after conditioning on extensive demo- graphic and behavioral variables. We also characterize the incremental explanatory power our data would require to enable observational methods to successfully measure advertising effects. Our findings suggest that commonly used observational approaches based on the data usually available in the industry often fail to accurately measure the true effect of advertising. Keywords: Digital Advertising, Field Experiments, Causal Inference, Observational Methods, Advertising Measurement.

  • UK Magazine ABC Review
    UK Magazine ABC Review January-June 2009 13 th August, 2009 Weeklies report declines across most sectors Overall Market: -2% POP Aggressive price promotions and increased TV investment are standard marketing tactics used to buoy figures in this hugely competitive market. Increasingly publishers such as Bauer and Northern and Shell are using the breadth of their portfolios to help drive circulation in the form of multipack offers. HIGHS OK! Magazine is back in the number one spot in celebrity market (+18% pop). The “Jade effect”, heavy TV investment and multi pack promotions across other Northern and Shell titles have all helped OK! recoup circulation lost in the previous ABC result. Taking a closer look, the bumper sales of Jade Goody issues show huge circulation spikes which have greatly buoyed the overall circulation figures. LOWS Now Magazine posted dismal results (-11% pop). IPC’s celebrity flagship title is hoping to win back readers through its recent re-design delivering a more upbeat take on celebrity news and increased fashion coverage. Celebrity The right editorial mix and heavy cut pricing pays off for Reveal (+17% pop) Heat Magazine’s editorial stance continues to show signs of fatigue despite Bauer’s multipack offers with Closer (-5% pop) Hello magazine suffers its biggest decline, driven mainly by the lack of top-end celebrity exclusives that usually help spike circulations (-6% pop) Fashion Look’s unique High Street shopping coverage continues to hit the right note in these times (static pop) Once again, up market weekly

  • OFA Workshop 2021 Session Abstracts
    OFA Workshop 2021 Session Abstracts Keynote Evolution of Interconnects and Fabrics to support future Compute Infrastructure Debendra Das Sharma, Intel Corporation High-performance workloads demand heterogeneous processing, tiered memory architecture including persistent memory, and infrastructure accelerators such as smart NICs to meet the demands of emerging applications in Artificial Intelligence, Machine Learning, Analytics, Cloud Infrastructure, Cloudification of the Network and Edge, communication systems, and high-performance Computing. Interconnect is a key pillar in this evolving computational landscape. Recent advances in I/O interconnects such as PCI Express and Compute Express Link with its memory and coherency semantics has made it possible to pool computational and memory resources at the rack level using low latency, higher throughput and memory coherent access mechanisms. We are already at a point where networking fabrics and tightly coupled load- store interconnects have overlapping coverage with some common attributes like standardized fabric manager for managing resources, low-latency message passing across nodes, and shared memory across multiple independent nodes. The traditional I/O interconnects are making changes to their load-store semantics to provide efficient access mechanisms for fabrics with advanced atomics, acceleration, smart NICs, persistent memory support etc. In this talk we will explore how synergistic evolution across interconnects and fabrics can benefit the compute infrastructure of the future.

The eight reports presented represent different dimensions of science education. Each provides a review of a given dimension and/or a goal of science teaching and suggests ways that current knowledge might affect practice. Reports focus on:(1) a review of some major studies in instruction, with suggestions for applications to science/mathematics curricula (J. Stallings);(2) information-processing psychology and a brief description of a science project using its methodology (J. Larkin); (3) role of instruction in the development of problem-solving skills in science (R. Ronning and D. McCurdy); (4) developing creativity as a result of science instruction (J. Penick); (5) deriving classroom applications from Piaget's model of intellectual development (D.
