The Data Journalism Handbook

The Data Journalism Handbook: Towards a Critical Data Practice provides a rich and panoramic introduction to data journalism, combining both critical reflection and practical insight. It offers a diverse collection of perspectives on how data journalism is done around the world and the broader consequences of datafication in the news, serving as both a textbook and a sourcebook for this emerging field. With more than 50 chapters from leading researchers and practitioners of data journalism, it explores the work needed to render technologies and data productive for journalistic purposes. It also gives a “behind the scenes” look at the social lives of data sets, data infrastructures, and data stories in newsrooms, media organizations, start-ups, civil society organizations and beyond. The book includes sections on “doing issues with data,” “assembling data,” “working with data,” “experiencing data,” “investigating data, platforms and algorithms,” “organizing data journalism,” “learning data journalism together” and “situating data journalism.

International collaboration schemes in earth and environmental sciences : IGEC programmes and UNESCO IHP

There is a lack of studies that investigate how internationalization of science can effectively contribute to the globalization of environmental knowledge. Two cases of international collaboration programmes are analyzed from a science and innovation research perspective: (1) The organizational scheme of the International Global Environmental Change (IGEC) programmes in the ICSU tradition, and (2) the International Hydrological Programme (IHP). led by the UNESCO. The paper draws on two analytical distinctions: Firstly, following Turner et al. (1990), systemic global change is distinguished from local or regional environmental change that becomes global by worldwide accumulation. Secondly, collaboration programmes that belong to the social system of science are distinguished from programmes at the intersection of scientific and political spheres. Both cases are compared in terms of their (a) rationales for international collaboration, (b) their organisational structure and fundings, (c) international participation and (d) linkages between problem structure and collaboration. Representative and contrasting examples, their juxtaposition illustrates actual strategies and various constraints faced by scientific and intergouvernmental agencies promoting international collaboration in S & T for sustainability and capacity development. The paper reports research of my ongoing dissertation project under the working title Internationalization in environmental research: The case of freshwater. --

Selection of Secondary School Teachers: Perceptions of School Adminstrators Concerning Criteria, Procedures, and Problems

Tills study of secondary teacher selection ascertained which selection criteria administrators regarded as important and which criteria were used, ascertained which procedures administrators regarded as important and which procedures were used, and ascertained which problems administrators encountered in selecting secondary teachers. An Analysis of Variance procedure was conducted to ascertain whether differences existed in administrators\u27 perceptions related to the size of school, to the location of the school, and to administrative role. Data were collected by securing responses to a questionnaire mailed to a stratified (by enrollment size) random sample of 768 public school administrators in North Dakota, South Dakota, and northwestern Minnesota. Demographic questions were included. The most valued criteria were ability to relate to students and ability to get along with others, while the most utilized criteria were ability to relate to students and ability to control students. The most valued procedures were phone call to previous employer and principals involved in interview, while the most utilized procedures were personal references and letter of application. The highest ranked problems were inadequate salary or benefits and too few good applicants. The demographic differences were analyzed by examining clusters of similar items. A numDer of significant differences were found between different-sized schools regarding which criteria clusters and procedures clusters were regarded as important and reportedly used. Larger schools placed more value and reported greater utilization in all the criteria clusters and almost all of the procedures clusters. Problems clusters grew in seriousness as the size of the school decreased. No differences were found between variously located schools regarding which criteria clusters and procedures clusters were regarded as important or reportedly used. The problems clusters grew in seriousness as the distance of the school from a community of 25,GOO increased. Superintendents placed greater value on and reported higher utilization of all criteria clusters than did secondary principals. Superintendents placed more emphasis on the procedures clusters of examinations and background, while secondary principals placed greater value on interviews. There were no significant differences between superintendents and principals regarding the perceived seriousness of the various problems clusters

Effective Resource and Workload Management in Data Centers

The increasing demand for storage, computation, and business continuity has driven the growth of data centers. Managing data centers efficiently is a difficult task because of the wide variety of datacenter applications, their ever-changing intensities, and the fact that application performance targets may differ widely. Server virtualization has been a game-changing technology for IT, providing the possibility to support multiple virtual machines (VMs) simultaneously. This dissertation focuses on how virtualization technologies can be utilized to develop new tools for maintaining high resource utilization, for achieving high application performance, and for reducing the cost of data center management.;For multi-tiered applications, bursty workload traffic can significantly deteriorate performance. This dissertation proposes an admission control algorithm AWAIT, for handling overloading conditions in multi-tier web services. AWAIT places on hold requests of accepted sessions and refuses to admit new sessions when the system is in a sudden workload surge. to meet the service-level objective, AWAIT serves the requests in the blocking queue with high priority. The size of the queue is dynamically determined according to the workload burstiness.;Many admission control policies are triggered by instantaneous measurements of system resource usage, e.g., CPU utilization. This dissertation first demonstrates that directly measuring virtual machine resource utilizations with standard tools cannot always lead to accurate estimates. A directed factor graph (DFG) model is defined to model the dependencies among multiple types of resources across physical and virtual layers.;Virtualized data centers always enable sharing of resources among hosted applications for achieving high resource utilization. However, it is difficult to satisfy application SLOs on a shared infrastructure, as application workloads patterns change over time. AppRM, an automated management system not only allocates right amount of resources to applications for their performance target but also adjusts to dynamic workloads using an adaptive model.;Server consolidation is one of the key applications of server virtualization. This dissertation proposes a VM consolidation mechanism, first by extending the fair load balancing scheme for multi-dimensional vector scheduling, and then by using a queueing network model to capture the service contentions for a particular virtual machine placement
