This chapter describes an approach to estimate reservoir productivity during the active exploration and development of a geothermal prospect. This approach allows a reservoir model to be updated by overcoming the severe time limitations associated with accessing sites for drilling and well testing under snowy and mountainous conditions. Performed in parallel with the conventional standard approach, the new approach enables us to obtain a first estimate of the reservoir productivity at an early time and to make successful project management decisions. Assuming a practical geothermal field, the procedures of the new approach are demonstrated here in detail. Finally, frequency distributions for the expected production rates and changes in the reservoir pressure at an arbitrary time are obtained during an assumed operational period.

Recent issues around reproducibility, best practices, and cultural bias impact naturalistic observational approaches as much as experimental approaches, but there has been less focus on this area. Here, we present a new approach that leverages cross-laboratory collaborative, interdisciplinary efforts to examine important psychological questions. We illustrate this approach with a particular project that examines similarities and differences in children’s early experiences with language. This project develops a comprehensive start-to-finish analysis pipeline that is publicly available for use, sensitive to cultural differences, and flexible to address a variety of research questions.

Producing accessible content for the Web is a rather complex task. Standards, rules and principles that offer largely useful recommendations for accessible content do indeed exist, but they are not adequately enforced and supported by actual implementations. It is fairly frequent for content authors to produce material that ends up not being accessible without even noticing it, even when using additional tools and services. Yet, most of the existing recommendations for accessible web resources center around the addition of reasonably simple markup with a clear declarative purpose in their design. How therefore is it possible that producing truly accessible content is such a rare occurrence? In this paper, we posit that an important justification of this, in addition to well-known lack of interest and lack of awareness, is the difficulty of evaluating and perceiving the correctness or wrongness of the generated assistive markup by non-disabled content authors and tool designers. Designers have serious difficulties when evaluating the effectiveness and correctness of the accessibility of their works, and existing tools do little or nothing to reduce the "handicap". Under these assumptions, we aim to describe an innovative approach based on declarative markup to improve the design and evaluation the accessibility of web pages. In particular, our strategy encompasses the combined usage of a declarative framework of accessible web components, capable of enforcing best-practices and conformance to accessibility standards, as well as automated tools to test for the accessibility of web content and, in addition, a new approach to manual tools to let developers and content creators examine visually the accessibility issues so that they can make sense of their impact on people with disabilities.

In a recent article, Salganik et al. describe a new approach to managing survey data in service of the Fragile Families Challenge, which they call “treating metadata as data.” Although the approach that they present is a good first step, a more ambitious proposal could improve survey data analysis even more substantially. I recommend that data collection efforts distribute an open-source set of tools for working with a particular data set that I call data-specific functions. The goal of these functions is to codify best practices for working with the data in a set of functions for commonly used statistical software. These functions would be jointly developed by the users and distributers of the data. Building such functions would both shorten the learning curve for new users, and would improve the quality of the data, by making tacit knowledge about problems with the data explicit and easy to act on.

The article is devoted to the study of the leading foreign countries practice in the state regulation of eco-innovation financing and the opportunity analysis of its use in Kazakhstan. The author analyzes the main sources and ways to organize financing of eco-innovations, as well as international programs for sustainable public procurement. International practice shows that investing financial resources to resolve environmental and climate problems is an essential component of sustainable development. The author identifies the main barriers to the development of “green” Finance in Kazakhstan. The recommendations on financing eco-innovations in Kazakhstan were developed based on the best practices studied.

The creation of a digital archive database system for the Pitjantjatjara and Yankunytjatjara people in Central Australia has been a challenging information technology (IT) project requiring unique thinking about database design, implementation and deployment. What might seem like sound, standards-based IT practice in a typical urban or academic location becomes unworkable in the physical realities of remote Australia and in the context of indigenous Australian cultural sensitivities. Based on the experience of the Ara Irititja Project, this chapter outlines the central issues facing the development of archive databases for indigenous peoples in remote Australia and points towards the need for a new approach to IT best practices in this context.

AbstractGas lift optimization has been a classic problem since its inception. The problem with currently practiced optimization, the gas lift performance curve (GLPC), was the sole requirement for exhaustive calculation that has to be performed every time changes to the reservoir are acknowledged. The approach of mechanistic modeling has been proven to be a powerful tool to complement the analysis of GLP curves, especially in complex, multi-well gas lift system. This publication offers a new approach in modeling the progression of flow pattern map (FPM) in case of reservoir pressure decline. The findings presented in this publication encourage the hypothesis that FPM can be used with minimum alteration should there be any changes in reservoir pressure.

The quality of data produced by citizen science (CS) programs has been called into question by academic scientists, governments, and corporations. Their doubts arise because they perceive CS groups as intruding on the rightful opportunities of standard science and industry organizations, because of a normal skepticism of novel approaches, and because of a lack of understanding of how CS produces data. I propose a three-pronged strategy to overcome these objections and improve trust in CS data. Develop methods for CS programs to advertise their efforts in data quality control and quality assurance (QCQA). As a first step the PPSR core could incorporate a field that would allow programs to point to webpages that document the QAQC practices of each program. It is my experience that many programs think carefully about data quality, but the CS community currently lacks an established protocol to share this information. Define and implement best practices for generating biodiversity data using different methods. Wiggins et al. 2011 published a list of approaches that can be used for QCQA in CS projects but how these approaches should be implemented has not been systematically investigated. Measure and report data quality. If one takes the point of view that citizen science is akin to a new category of scientific instruments, then the ideas of instrument measurement and calibration can be applied CS. Scientists are well aware that any instrument needs to be calibrated before its efficacy can be established. However, because CS is new approach, the specific procedures needed for different kinds of programs are just now being worked out for the first time.

If one takes the point of view that citizen science is akin to a new category of scientific instruments, then the ideas of instrument measurement and calibration can be applied CS. Scientists are well aware that any instrument needs to be calibrated before its efficacy can be established. However, because CS is new approach, the specific procedures needed for different kinds of programs are just now being worked out for the first time. The strategy outlined above faces some specific challenges. Citizen science biodiversity programs must address two important problems that standard scientific entities encounter when sampling and monitoring biodiversity. The first is correctly identifying species. For citizens this can be a problem because they often do not have the training and background of scientist teams. Likewise, it may be difficult for CS projects to manage updating and maintaining the taxonomies of the species being investigated. A second set of challenges is the diverse kinds of biodiversity data collected by CS programs. For instances, Notes from Nature decodes that labels of museum specimens, Snapshot Serengeti identifies species of large mammals from camera trap photographs, iNaturalist collections images of species and then has a crowdsource identification processs, while eBird collects observations of birds that are immediately filtered with computer algorithms for review by the observer and if, subsequently flagged, reviewed by a local expert. Each of these programs likely requires a different set of best practices and methods to measure data quality.
