Abstract:
We developed and validated the Conceptual Assessment of Natural Selection (CANS), a multiple-choice test designed to assess how well college students understand the central principles of natural selection. The expert panel that reviewed the CANS concluded its questions were relevant to natural selection and generally did a good job sampling the specific concepts they were intended to assess. Student interviews confirmed questions on the CANS provided accurate reflections of how students think about natural selection. And, finally, statistical analysis of student responses using item response theory showed that the CANS did a very good job of estimating how well students understood natural selection. The empirical reliability of the CANS was substantially higher than the Force Concept Inventory, a highly regarded test in physics that has a similar purpose.

Concerns about the anthropogenic ecological degradation of the planet—deforestation, species endangerment, pollution, and an increasing carbon footprint—have prompted numerous studies calling for wide-ranging, comprehensive global programs. In this regard, Tim Flannery's effort in Here on Earth to enlist Alfred Russel Wallace, a nineteenth-century naturalist, in the service of a twentieth-century idea falls prey to presentism on the grounds of a conceptual misunderstanding and incomplete or interpolated primary data.

Abstract. The Montesinho Natural Park (MNP), with an area of about 750 km2, is one of the largest protected areas in Portugal. Since its inauguration as a natural park in 1979, geological and geomorphological aspects have not been taken into consideration in its nature conservation policies. Over the last few years, this deficit has been compensated with an assessment of its geomorphological heritage. The assessment was made possible due to a research project on the geological heritage of the natural parks of north-eastern Portugal.The assessment method propagated herein proposes a clear definition of three types of geomorphosites: Single places, geomorphological areas or panoramic viewpoints. Further, it proposes as two-staged approach to assessment with inventory compilation followed by quantification of value. Inventory compilation, for example, involves the identification and qualitative assessment of potential geomorphosites and, therefore, the selection and characterization of geomorphosites. The quantification stage includes the numerical assessment of sites and their final ranking. The values are numerically assessed using selected criteria. The implementation of this approach in the MNP led to the identification of 154 potential geomorphosites, of which only 26 were selected after the qualitative assessment or characterisation process. The numerical assessment of the sites and their ranking allowed a final selection of 13 sites for public use.

Abstract:
Selection as a mode of causation is central to operant psychology. Response variation and selection by consequences corresponds to phenotypic variation, to differential survivability, and to reproduction of variants. In natural selection, genes code for phylogenic history but no analogous processes exists for coding behavioral history. Neuroscience suggests potential processes but the conceptual status of these events requires clarification.

Abstract:
Science teachers and researchers note that students must correctly understand the role of natural selection in evolution to make sense of biology. The level of understanding of natural selection can be assessed using the Conceptual Inventory of Natural Selection (CINS) which is a 20-item multiple-choice test that incorporates student misconceptions as distractors. In the present study, Item Response Theory (IRT) was used to analyze the occurance of misconceptions on the CINS among 1192 students in an introductory non-majors biology course. The four most difficult topics in the CINS are: (a) how change occurs in a population; (b) origin of variation; (c) heritability of variation; and (d) the origin of species. Students with an average level of understanding of natural selection favored Teleological explanations for why organisms adapt to their environment, namely that organisms change because they need or want to change. These same students favored the Lamarckian explanation for how organisms adapt, namely by passing on acquired traits to offspring. Presence of such misconceptions in students with an average understanding of natural selection highlights the need for biology teachers to make an added effort to create dissatisfaction with teleological and Lamarckian explanations in the minds of their students.

Abstract:
This study examined what effects, if any, cultural factors have on conceptual knowledge of evolutionary theory through natural selection. In particular, the study determines if Latino and non-Latino students differ in their misconceptions of natural selection and, if so, whether or not cultural factors could be the reason why such differences exist. A total of 1179 college students attending eight Hispanic-Serving Institutions in Texas participated in the study. The results revealed that the top two challenging natural selection concepts for students to comprehend were causes of phenotypic variation, i.e., mutations are intentional, and selective survival based on heritable traits. In addition, no statistical significant differences were found between the Latino and non-Latino students and the top four natural selection misconceptions between the groups were similar. Not even religion was found to directly contribute to evolutionary misconceptions; even though, it serves as the core of an individual’s beliefs system. However, traditional teaching methods, inadequately trained biology school teachers, lessons poor in content, insufficient teaching time, and lack of age appropriate tasks, as well as, poorly defined evolutionary terms are actually the main causes for evolutionary misconceptions.

Abstract:
DARWIN’S THEORY OF EVOLUTION ranks among the most influential of modern scientific theories. Applying the methodology of COGNITIVE SEMANTICS , this study investigates how metaphors based on domains of JOURNEY, STRUGGLE, TREE and HUMAN AGENCY serve to conceptualize key concepts of Darwin’s theory — such as evolutionary change, natural selection, and relationships among organisms. At the outset the author identifies original metaphors in The Origin of Species, to turn to their realizations in modern discourse on evolution in later chapters. Thus, the study uncovers how metaphors contribute to structuring the theory by expressing it in a coherent and attractive way, and how they provide mental tools for reasoning. As the first comprehensive study of conceptual metaphors that underlie Darwin’s theory and affect the way we talk and think about evolution, it may be of interest not only to linguists and evolutionary biologists but also to anyone interested in the interconnection between thought and language.

Abstract:
Since its origin in the early 20th century, the modern synthesis theory of evolution has grown to represent the orthodox view on the process of organic evolution. It is a powerful and successful theory. Its defining features include the prominence it accords to genes in the explanation of development and inheritance, and the role of natural selection as the cause of adaptation. Since the advent of the 21st century, however, the modern synthesis has been subject to repeated and sustained challenges. In the last two decades, evolutionary biology has witnessed unprecedented growth in the understanding of those processes that underwrite the development of organisms and the inheritance of characters. The empirical advances usher in challenges to the conceptual foundations of evolutionary theory. Many current commentators charge that the new biology of the 21st century calls for a revision, extension, or wholesale rejection of the modern synthesis theory of evolution. Defenders of the modern synthesis maintain that the theory can accommodate the exciting new advances in biology, without forfeiting its central precepts. The original essays collected in this volume—by evolutionary biologists, philosophers of science, and historians of biology—survey and assess the various challenges to the modern synthesis arising from the new biology of the 21st century. Taken together, the essays cover a spectrum of views, from those that contend that the modern synthesis can rise to the challenges of the new biology, with little or no revision required, to those that call for the abandonment of the modern synthesis.

This chapter proposes a conceptual roadmap to homology, with the goal of supporting the research program of developmental evolution that seeks to explain the patterns of phenotypic diversity. It offers a mechanistic developmental and evolutionary explanation of the evolution of body plans and the origin of character identities. It also examines the difference between the origin of homologs (that is, novelties) and their modification by natural selection (that is, adaptation); the limits of homology, focusing on the lack of individuality of body parts; homologous genes; characters and character states; variational modalities; character identity and repeated body parts; and character swarms. Finally, it considers alternative conceptualizations of homology, conceptual liberalism, and how to sort patterns of morphological variation.

Abstract:
This chapter considers a general description of natural selection: the Price equation. Developed by George Price in the late 1960s, the Price equation can be applied to the change of any quantity under any selective regime. It is thus not limited to considering simple haploid single-locus traits, unlike the replicator dynamics, and indeed it is not even limited to considering evolutionary selection. The Price equation provides an instantaneous description of selection in action. The simplicity of the equation makes it a useful conceptual tool for understanding selective processes such as natural selection. The chapter first describes the general Price equation before discussing its use to understand genetic selection. It then shows how the Price equation can be used to derive two classical results from population and quantitative genetics: Fisher's “fundamental theorem of natural selection” and the breeder's equation.

This chapter presents the overview of concurrent design process of green composite products with special focus on conceptual design stage of natural fiber composites product development. Design of green composites product especially during the early product development stage requires three main aspects in product design which are materials, design and manufacturing process to satisfy lower cost, high quality and fast development time requirements in order to ensure successful product launch into the market. In this chapter, the concurrent design process of green composite products are discussed involving several main stages in product development such as green composite materials selection for both natural fiber and matrix constituents, conceptual design development and concept design selection of green composite products, and green composites manufacturing process selection. In addition, discussion on life cycle assessment of green composites is also included in order to provide further insight of the sustainability design requirements to the overall product development process.

Abstract:
Uplift and erosion scenarios must be analysed since these natural phenomena are expected to be inevitable at most districts in Japan. It is increasingly important to enhance the confidence in uplift and erosion scenarios even if these processes occur far into the future, since performance assessment cut-off times have not yet been defined. In this context, this study specifies uplift and erosion scenarios considering uplift and fluvial erosion based on Japanese geological and topographical characteristics and describes a conceptual model focused on a comprehensive fluvial erosion process that were based on generalisations of field observations. A series of bounding analyses have been carried out to define parameter conditions to satisfy hypothetical dose criteria considering various uplift and erosion rates and transmissivities. The results based on the conservative assumptions show that there are some cases that satisfy the hypothetical dose criterion in each phase for the likely scenario (base scenario: 10 μSv/y), which is a targeted dose suggested by the Nuclear Safety Commission for sub-surface disposal. All cases are below 300 μSv/y, which is the targeted dose for the less-likely scenario (variant scenario) as well as the dose constraint for radioactive waste disposal by the International Commission on Radiological Protection. The discussion also provides that a loss of inventory in the engineered barrier system by accelerating release of nuclides does not significantly decrease the doses in later phases due to inherent attributes of the repository system, i.e. multiple barriers and multiple safety functions. In principle, the influence of uplift and erosion should be reduced by appropriate site selection and design, to the extent possible; to ensure that sufficient nuclides decay while the repository is deep underground.

Full text
Abstract:
When a buried pipeline is exposed in the middle of a river, the need of a mitigation action immediately arises. Lowering the pipeline by natural flexion is sometimes chosen after competing in magnitude, complexity and cost with other alternatives such as river bank and bed erosion control protections. Although simple in its conceptual design, its implementation requires taking into consideration several factors that can affect its successful outcome in terms of the final position of the pipeline and the remediation measures needed to restore the terrain and environment to its original situation. Five different field cases are presented: Río Colorado, Río Santa María, Río Negro and Río Suquía, all of them located at northern Argentina, and a fifth one placed at the Patagonian desert. For each of them references are made regarding the following issues: reasons for the selection of this option, in or out of service movement operation, depth of burial, design of the lowering curve based on pipe allowable tensions, topographic reference system, ditch design, drainage and stabilization, need for river diversion, lowering equipment, ditch interceptors design, ditch filling and soil compaction procedure, and ROW remediation. Finally, a set of recommendations are included as a way to share this experience and provide a guideline for future works.

Abstract Based on global search/optimization techniques called genetic algorithms, a new approach to the conceptual design of mechanisms is proposed. Emulating “natural” genetics and selection, competing types of mechanisms are treated as species and different dimensions are evaluated for each type simultaneously. The problem formulation is straight-forward, similar to an optimization problem. The result may be a spectrum of similar or different mechanisms, depending on whether multiple optimal solutions exist. The computational power required to utilize this approach is acceptable for most conceptual design problems.

Full text
Abstract:
Abstract For years the drilling industry has used sour service drill pipe within a narrow set of specifications and industry guidelines. That left room for original equipment manufacturers (OEM) to have customization on an iterative basis, which resulted in a wide product offering to fulfill operator needs. While this method worked, it did not lead to building the product in the most efficient and economical manner. As a result of this product diversity, drilling engineers could specify the best product to deliver their projects when running drilling models, only to have to redesign it around what is effectively available on rigs or for rental. This disconnect puts pressure on the industry players and is the result of a lack of standardization. We wiped the board to provide a simple solution that is more suited to allow alignment between operators, contractors, and rental companies. The new philosophy is based on the National Association of Corrosion Engineers (NACE) MR0175-2015 severity diagram, where environmental severity is defined in regions (1, 2, and 3), which have been used by oil companies’ engineers for their oil country tubular goods (OCTG) product selection. Even though the drill string will not be exposed to the well fluid for the same extended time and is surrounded by a more forgiving medium, the drilling fluid, the diagram allows a segmentation of customer's needs. This framework helped define targeted product properties. A research and development (R&D) and industrialization test campaign could then be started to confirm that sound product configurations could be offered with targeted properties. The study also explored the limitations imposed on connection make-up torque in a sour gas environment relative to the NACE severity diagram. Emphasis was given on methods to increase the make-up torque, which is needed to deliver the most extended reach wells that are now commonplace. The result of this two-year development campaign is a short list of grades with an optimized balance between pipe subcomponents strength and sulfide stress cracking (SSC) resistance. Region 1 (mild severity) products will offer as much tension and torque as possible, matching or exceeding these of API products, including excellent resistance to SSC, thus making drilling operation safer. Region 2 (medium severity) will offer products with medium to high strength and enhanced SSC resistance. Finally, region 3 (high severity) products will be aligned with the industry specifications for maximized SSC resistance and lower strength. This paper discusses a proactive approach that contrasts with a historical, more reactive one. As the drill stem technology leader, we saw an opportunity to drive this initiative that will benefit the drilling industry by offering a more natural way to select drill stem products. For the first time a sour service product range aligns with the needs of drilling engineers and the inventory of their selected service companies.

Abstract:
The potential risk of an offshore processing facility is the major important part in the oil and gas industry due to its limited space causing difficulties in evacuation. An offshore processing facility is normally exposed to flammable oil and gas in the operating phase. Especially, uncontrolled hydrocarbon leaks or ruptures of the equipment present main threats. These failures can lead to fire and explosion disaster. Some studies have proposed fire and explosion assessment methodologies and made fire and explosion assessment tools. These tools can provide risk assessments result using physical effect modelling software and following the related standards or engineering practices according to accident scenarios. Nevertheless, existing fire and explosion assessment procedures are still not comprehensive enough to applicate a specific process due to its complexity and are not clear which stage in a project is appropriate for applying it. This paper focuses only on explosion accidents and discusses the development of an explosion risk analysis procedure possible to apply at process flow diagram (PFD) level. The explosion risk analysis procedure using PFD has 6 steps; modelling of a process, scenario selection, inventory calculation, frequency calculation, consequence modelling and risk estimation. It starts at modelling of a specific process using process simulation software, HYSYS. The process modelling can be optimized by the existing methods and finally provide the PFD for the specific process. In the scenario selection step, the information required to perform a risk analysis is identified. The inventory calculation conducts to calculate the inventory of a defined segment after sizing of the equipment in the PFD. The frequency calculation consists of leak frequency and ignition probability. The leak frequency can be calculated with historical database and the ignition probability can be calculated with a specific ignition probability model. The consequence modelling is conducted by using physical effect modelling software, PHAST. It can provide the distance to specified overpressure. Finally, at the risk estimation step, the risk results are evaluated. This procedure can help to applicate a specific process easily and provide explosion risk assessment tool at PFD level. This paper conducts the case study for a liquefied natural gas floating production storage offloading (LNG-FPSO) which is one of the representative offshore processing facilities. Especially, a natural liquefaction process in a LNG-FPSO, which liquefies the processed natural gas to store in a storage tank of a LNG-FPSO, is the most important process in terms of cost and risk. In the situation the most of ongoing or prospective projects for LNG-FPSO adopt dual mixed refrigerants (DMR) liquefaction process, the representative configurations of the DMR liquefaction processes are evaluated and compared. It can help decision making through providing which configuration has an advantage in terms of explosion accidents.

Abstract:
Abstract Novi Han Repository is the only existing repository in Bulgaria for the disposal of radioactive waste from nuclear applications in industry, medicine and research. The repository was constructed in the early sixties according to the existing requirements. It was operated by the Institute for Nuclear Research and Nuclear Energy for more than thirty years without any accident or release of radioactivity to the environment, but without any investment for upgrading. As a consequence, the Bulgarian Nuclear Safety Authority temporarily stopped the operation of the repository in 1994. The measures for upgrading Novi Han Repository, supported by the IAEA with TC Project BUL/4/005 “Increasing Safety of Novi Han Repository”, are presented in this paper. They consist of: assessment of radionuclide inventory and future waste arisings, characterization of disposal vaults, characterization of the site, safety assessment, upgrading of the monitoring system, option study for the selection of treatment and conditioning processes and the development of a conceptual design for low and intermediate level waste processing and storage facility, immediate measures for improvement of the existing disposal vaults and infrastructure, and construction of above-ground temporary storage structures. The outstanding activities for re-opening of the Novi Han Repository and implementation of the measures for reconstruction of the Novi Han Repository are discussed.

Abstract:
Cheboksary reservoir impact to the coast is manifested in the geophysical impact associated with abrasion activities. Geomorphological area of influence at the moment reaches a width of about 40 m, where are the coasts reformation (erosion, collapse, slumping, sliding, transfer or accumulation of sediments, waterlogged processes). Hydrogeological impact is effect on the level of groundwater. We have proposed the conceptual foundations of functional zoning of the reservoir banks that will help to optimize its operation. Selection zones came in accordance with the principles of landscape planning: 1. The zone of strict water protection: the main purpose – preservation of needing special protection areas. 2. The zone of moderate restrictions: preservation extensively used landscapes. 3. The zone of partial restrictions: improving the pre-emptive particularly vulnerable areas and changing intensity or type of use. 4. The zone of conservation of natural components in agricultural landscapes: ensuring health of the natural environment in the habitats used in agricultural economy. 5. The zone of preservation of vacant space and the natural environment in the settlements: to maintain the required quantity and quality of available green space in the large towns. 6. The zone of improving heavily used areas: elimination of harmful stress and environmental sanitation in the countryside where economic activities and the lack of measures to reduce their risks lead to degradation natural system.

Abstract:
Abstract Automation has enabled design of increasingly complex products, services, and systems. Advanced technology enables designers to automate repetitive tasks in earlier design phases, even high level conceptual ideation. One particularly repetitive task in ideation is to process the large concept sets that can be developed through crowdsourcing. This paper introduces a method for filtering, categorizing, and rating large sets of design concepts. It leverages unsupervised machine learning (ML) trained on open source databases. Input design concepts are written in natural language. The concepts are not pre-tagged, structured or processed in any way which requires human intervention. Nor does the approach require dedicated training on a sample set of designs. Concepts are assessed at the sentence level via a mixture of named entity tagging (keywords) through contextual sense recognition and topic tagging (sentence topic) through probabilistic mapping to a knowledge graph. The method also includes a filtering strategy, the introduction of two metrics, and a selection strategy for assessing design concepts. The metrics are analogous to the design creativity metrics novelty, level of detail, and a selection strategy. To test the method, four ideation cases were studied; over 4,000 concepts were generated and evaluated. Analyses include: asymptotic convergence analysis; a predictive industry case study; and a dominance test between several approaches to selection of high ranking concepts. Notably, in a series of binary comparisons between concepts that were selected from the entire set by a time limited human versus those with the highest ML metric scores, the ML selected concepts were dominant.

Abstract:
This report presents detailed histograms of data from the Regulated Substances Library (RSL) developed by the Illinois Department of Transportation (IDOT). RSL data are provided for state and IDOT region, IDOT district, and county spatial subsets to examine the spatial variability and its relationship to thresholds defining natural background concentrations. The RSL is comprised of surficial soil chemistry data obtained from rights-of-way (ROW) subsurface soil sampling conducted for routine preliminary site investigations. A selection of 22 inorganic soil analytes are examined in this report: Al, Sb, As, Ba, Be, Cd, Ca, Cr, Co, Cu, Fe, Pb, Mg, Mn, Hg, Ni, K, Se, Na, Tl, V, and Zn. RSL database summary statistics, mean, median, minimum, maximum, 5th percentile, and 95th percentile, are determined for Illinois counties and for recognized environmental concern, non-recognized environmental concern, and de minimis site contamination classifications.
