Optimal Color Range Reporting in One Dimension
Color (or categorical) range reporting is a variant of the orthogonal range
reporting problem in which every point in the input is assigned a \emph{color}.
While the answer to an orthogonal point reporting query contains all points in
the query range , the answer to a color reporting query contains only
distinct colors of points in . In this paper we describe an O(N)-space data
structure that answers one-dimensional color reporting queries in optimal
time, where is the number of colors in the answer and is the
number of points in the data structure. Our result can be also dynamized and
extended to the external memory model
Modelling workplace contact networks: the effects of organizational structure, architecture, and reporting errors on epidemic predictions
Face-to-face social contacts are potentially important transmission routes
for acute respiratory infections, and understanding the contact network can
improve our ability to predict, contain, and control epidemics. Although
workplaces are important settings for infectious disease transmission, few
studies have collected workplace contact data and estimated workplace contact
networks. We use contact diaries, architectural distance measures, and
institutional structures to estimate social contact networks within a Swiss
research institute. Some contact reports were inconsistent, indicating
reporting errors. We adjust for this with a latent variable model, jointly
estimating the true (unobserved) network of contacts and duration-specific
reporting probabilities. We find that contact probability decreases with
distance, and research group membership, role, and shared projects are strongly
predictive of contact patterns. Estimated reporting probabilities were low only
for 0-5 minute contacts. Adjusting for reporting error changed the estimate of
the duration distribution, but did not change the estimates of covariate
effects and had little effect on epidemic predictions. Our epidemic simulation
study indicates that inclusion of network structure based on architectural and
organizational structure data can improve the accuracy of epidemic forecasting
models.Comment: 36 pages, 4 figure
International Research Symposium on Talent Education, Part 4: The joys and benefits of Suzuki group class
This is the fourth article in a series reporting the findings of a large-scale demographic study of Suzuki teachers in Canada and the United States. Previous articles introduced the research, reporting on basic demographic statistics, teacher training, studio size, and structure of group classes. In this article we report on the results of an open-ended response question regarding the benefits of student participation in Suzuki group class
Improving Performance in Practice: Rx for Primary Care
Summarizes the structure of a state-based, RWJF-funded program designed to help small primary care practices improve performance in diabetes or asthma care through measurement, reporting, and analysis. Presents early outcomes and lessons learned
Ensuring Trust in One Time Exchanges: Solving the QoS Problem
We describe a pricing structure for the provision of IT services that ensures
trust without requiring repeated interactions between service providers and
users. It does so by offering a pricing structure that elicits truthful
reporting of quality of service (QoS) by providers while making them
profitable. This mechanism also induces truth-telling on the part of users
reserving the service
Comment on "Under-reported data analysis with INAR-hidden Markov chains"
In Fernandez-Fontelo et al (Statis. Med. 2016, DOI 10.1002/sim.7026) hidden
integer-valued autoregressive (INAR) processes are used to estimate reporting
probabilities for various diseases. In this comment it is demonstrated that the
Poisson INAR(1) model with time-homogeneous underreporting can be expressed
equivalently as a completely observed INAR(inf) model with a geometric lag
structure. This implies that estimated reporting probabilities depend on the
assumed lag structure of the latent process.Comment: This is the pre-reviewing version of a letter published in Statistics

Best practice in undertaking and reporting health technology assessments : Working Group 4 report
[Executive Summary] The aim of Working Group 4 has been to develop and disseminate best practice in undertaking and reporting assessments, and to identify needs for methodologic development. Health technology assessment (HTA) is a multidisciplinary activity that systematically examines the technical performance, safety, clinical efficacy, and effectiveness, cost, costeffectiveness, organizational implications, social consequences, legal, and ethical considerations of the application of a health technology (18). HTA activity has been continuously increasing over the last few years. Numerous HTA agencies and other institutions (termed in this report “HTA doers”) across Europe are producing an important and growing amount of HTA information. The objectives of HTA vary considerably between HTA agencies and other actors, from a strictly political decision making–oriented approach regarding advice on market licensure, coverage in benefits catalogue, or investment planning to information directed to providers or to the public. Although there seems to be broad agreement on the general elements that belong to the HTA process, and although HTA doers in Europe use similar principles (41), this is often difficult to see because of differences in language and terminology. In addition, the reporting of the findings from the assessments differs considerably. This reduces comparability and makes it difficult for those undertaking HTA assessments to integrate previous findings from other HTA doers in a subsequent evaluation of the same technology. Transparent and clear reporting is an important step toward disseminating the findings of a HTA; thus, standards that ensure high quality reporting may contribute to a wider dissemination of results. The EUR-ASSESS methodologic subgroup already proposed a framework for conducting and reporting HTA (18), which served as the basis for the current working group. New developments in the last 5 years necessitate revisiting that framework and providing a solid structure for future updates. Giving due attention to these methodologic developments, this report describes the current “best practice” in both undertaking and reporting HTA and identifies the needs for methodologic development. It concludes with specific recommendations and tools for implementing them, e.g., by providing the structure for English-language scientific summary reports and a checklist to assess the methodologic and reporting quality of HTA reports
The implications of new financial reporting standards on New Zealand charities
This research aims to analyse the impact of new reporting standards on NZ charities. The research specifically focuses on the implications of new reporting standards of charities in areas like transparency, convenience for practitioners and accounting costs under new reporting standards. The research covers transparency aspects by trying to find the difference in truthful and accurate representation of charities in their annual financial reports after the introduction of new standards, compared to when charities were self-regulated under Generally Accepted Accounting Principles. The research also covers the aspect of practitioners’ convenience, by investigating whether new reporting standards made accounting practices for charities easier and clearer, or more complicated. Lastly, research was conducted to ascertain the increase or decrease in accounting cost for charities to comply with new financial reporting standards. The study used qualitative methodology for research. The data was collected through semi-structured interviews to gain in-depth knowledge of the impact of new reporting standards on charities. There were four participants in total, accountants working for different charities. The duration of each interview was approximately 20 minutes, and were conducted at the charity organisation’s premises. The method of analysis used for the research was content analysis.
The findings of the research suggest that the new reporting standards and statutory audit requirements have generally increased transparency within the charity sector in New Zealand. On the other hand, accounting costs have gone up for charities, especially Tier 2 and tier 3 charities. Charities that previously complied with IFRS have to face minimal effect on accounting cost. The convenience for practitioners has decreased since smaller charities are finding it difficult to comply with new reporting requirements and preparation of service performance reports which are now part of annual reporting. New financial reporting standards have provided a much-needed reporting structure, especially to Tier 3 and Tier 4 charities. Charities that complied with IFRS for their annual reporting found it easy to make the transition to the new reporting standards. In conclusion, the new reporting standards are a step in a right direction. However charities services need to hold regular workshops in every region for charities in order to provide more awareness about new reporting requirements to help charities through this transition phase. Small charities usually operate on a very limited budged, so templates and training for service performance reporting should be provided these are now a part of annual reports for Tier 3 and Tier 4 charities
